Definitions
- the technology described herein relates to a rigging system for suspension exercise training.
- Suspension exercise training is a form of bodyweight resistance exercise using a rigging system with ropes or straps to support the user while performing a variety of movements to increase strength and flexibility.
- Various forms of rigging systems have been designed to aid a user in performing suspension exercises.
- the rigging systems need to be able to attach to a fixed point above the user and be strong enough to support the user's weight plus additional force caused by the user when pulling on or moving while supported by the rigging system.
- Rigging systems for suspension exercise training also often include handles for ease of holding and grasping the device opposite the fixed end.
- the straps, cords, or ropes used in such rigging systems are often adjustable to accommodate different heights and relative locations for fixed points and different sizes of users. Due to the desire for adjustability, design challenges arise. For example, excess strap length can impede the user when performing an exercise. Further, connection to different types of fixed points can require multiple additional attachment components.
- a rigging system for use in performing suspension exercises.
- the rigging system includes a first strap, an first buckle, and a handle.
- the first buckle forms a distal end of the rigging system through which a first end portion of the first strap is threaded and in which the first strap is selectively secured.
- the first buckle further includes a first buckle body including a span and two sidewalls positioned on opposing sides of the span and connected to the span. The sidewalls are defined by respective perimeter edges.
- a resilient bumper surface is formed on the perimeter edges of the sidewalls.
- a retention structure is joined to the body that releasably secures the first strap within and with respect to the first buckle at a variety of positions.
- a handle is operatively associated with a second end of the first strap.
- a rigging system for use in performing suspension exercises.
- the rigging system includes a first strap and a second strap connected to each other by a lower buckle.
- a handle is further connected to an end of the second strap by a third strap.
- the lower buckle is connected to a first end of the first strap.
- the lower buckle includes a lower buckle body that defines a slot through which the second strap passes and a bulkhead around which the second strap loops whereby a length of the second strap is located below a length of the first strap when a second end of the first strap is joined to a fixed point located above the second strap such that the first and second straps hang vertically from the fixed point.
- a retention structure is joined to the lower buckle body that releasably secures the second strap within and with respect to the lower buckle at a variety of positions.
- the third strap is connected at both ends to an end of the second strap.
- the handle is supported by a length of a portion of the third strap.
- a rigging system for use in performing suspension exercises.
- the rigging system includes a first strap of a first length; a second may strap of a second length, a first buckle, a second buckle, and a handle.
- the first buckle may form a distal end of the rigging system through which the first length of the first strap is selectively secured.
- the second strap may be fixed at a first end to a first end of the first strap.
- the second length of the second strap is thus located below the first length of the first strap when a portion of the first strap between the first end and a second end is joined to a fixed point located above the second strap such that the first and second straps hang vertically from the point.
- the second length of the second strap may be selectively secured through the second buckle.
- the handle may be connected to a second end of the second strap in a fixed position such that a distance between second end of the second strap and the handle is constant.
- a rigging system for use in performing suspension exercises.
- the rigging system includes a first strap of a first length, a second strap of a second length connected to an end of the first strap, an elongate handle, and an ankle strap.
- the elongate handle may be connected to the second strap in an orientation normal to the first length of the first strap when the first strap is under tension.
- the ankle strap is formed as a resilient, self-supporting stirrup connected to the elongate handle, wherein lateral ends of the ankle strap are connected to lateral ends of the elongate handle.

- FIG. 15 is an isometric view of an alternate embodiment including two rigging systems without ankle straps and further including a connector bar that connects the handles of the two rigging systems together.
- a rigging system for use in performing suspension exercises are disclosed herein.
- the rigging system is configured for selective attachment to a fixed-point mount (e.g., a beam, a bar, a tree limb, or a door jamb), typically located at a position above the user's head.
- a handle on the opposite end of the rigging system hangs from this fixed point and is grasped by the user to support a portion of the user's weight while the user performs resistance exercises against a reduced portion of the user's body weight.
- the fixed point may be a doorjamb above the top of a door.
- a height adjustment buckle of the rigging system is designed to be positioned generally distal from a structure forming the handle during use of the rigging system. This is in contrast to other suspension exercise trainers in which the adjustment buckle is fixedly joined to the handle structure, thus locating the buckle in a position generally closer to the forearm during use of the rigging system.
- the height adjustment buckle can press against the arm, which is uncomfortable.
- adjusting the handle up and down becomes a two-step process, because after adjusting the height, the user must then manage the excess webbing to minimize interference of the webbing with the user's motion during a training exercise.
- the free end of the strap extending away from the height adjustment buckle will generally not come into contact with the user during the exercise. Since the excess webbing at the free end of the strap may be allowed to hang down freely during an exercise as it will generally not interfere with the user's motion, it does not need to be adjusted separately.
- An upper buckle which may also be referred to as a height adjustment buckle, can serve as a door anchor, or can cinch over a pull-up bar.
- a rubber outside edge helps to protect the doorframe from damage, and helps to grip a pull-up bar when cinched tight.
- the upper buckle also provides adjustability for positioning the lower buckle, allowing easy access for people of different heights, or for different ceiling heights.
- FIGS. 1A, 1B, and 1C depict an embodiment of a rigging system 100 for exercise training.
- Primary components of the rigging system 100 may include an upper buckle 102 , an upper strap 104 , a lower buckle 106 , a lower strap 108 , a handle 110 , an ankle strap 112 , a handle strap 114 , and a handle link 116 .
- the upper strap 104 joins the upper buckle 102 to the lower buckle 106 .
- An end portion of the upper strap 104 which for convenience may be referred to herein as the first end portion of the upper strap 104 , may be threaded through the upper buckle 102 and adjustably engaged therewith.
- Another end portion of the upper strap 104 which for convenience may be referred to herein as the second end portion of the upper strap 104 , may be connected to the lower buckle 106 preferably via a loop 105 formed in the second end of the upper strap 104 extending around a structure of the lower buckle 106 .
- the loop 105 in the upper strap 104 may be fixed in size and position as shown or it may alternatively be adjustable as further described herein.
- the upper buckle 102 may be attached to an optional fixed-point mount 260 via a mount strap 262 as further described below.
- the upper buckle 102 may also be attached to other fixed-point structures (e.g., bars, tree limbs, poles, etc.) via the mount strap 262 , another strap, or the upper strap 104 .
- the upper buckle 102 may provide a resistance stop for placement between a door and a doorjamb and function as the fixed point.
- a first end portion of the lower strap 108 may be adjustably connected to the lower buckle 106 on an opposite side of the lower buckle 106 from the attachment of the upper strap loop 105 .
- a second end portion of the lower strap 108 may be attached to the handle link 116 .
- the lower strap 108 has a fixed connection to the handle link 116 via a loop 109 .
- the loop 109 may be adjustable as further described herein below.
- a first end portion of the handle strap 114 may be connected to the handle link 116 via a handle strap loop 115 a formed in the first end.
- a similar handle strap loop 115 b may be formed in a second end portion of the handle strap 114 to similarly connect the second end to the handle link 116 .
- a middle section of the handle strap 114 supports or otherwise connects to the handle 110 as further described herein.
- the ankle strap 112 also attaches to the handle 110 and may be attached in a fixed position relative to the handle 110 as further described herein.
- the upper buckle 102 is shown in greater detail from multiple perspectives in FIGS. 2A-4C .
- the upper buckle 102 may be constructed around an upper buckle body 122 that provides a framework for other components of the upper buckle 102 .
- the upper buckle body 122 may be a monolithic piece formed of plastic, e.g., by injection molding.
- the plastic may be a high strength, abrasion and impact resistant, thermoplastic polyamide (nylon) formulation (e.g., Zytel® 43% glass-filled nylon to 30% glass-filled nylon, or carbon-filled nylon).
- the upper buckle body 122 may be formed from a stamped metal such as aluminum.
- the upper buckle body 122 and other components of the upper buckle 102 may be made of die cast steel to increase the strength of such components.
- Other components e.g., the lower buckle 106 and the handle link 116 ) may be similarly formed.
- the upper buckle body 122 may have opposing sidewalls 123 a, 123 b that are arranged parallel with respect to each other and are connected together by an upper buckle span 126 which holds the upper buckle sidewalls 123 a, 123 b in a position spaced apart from each other.
- the upper buckle sidewalls 123 a, 123 b may be formed as oval or oblong shapes as shown in the embodiments of FIGS. 2A-2C . However, the upper buckle sidewalls 123 a, 123 b may be formed in various other shapes as desired.
- the top edges of the upper buckle sidewalls 123 a, 123 b may be formed with corresponding symmetric depressions in positions adjacent to span 126 .
- the span 126 may be contoured from a front edge to a back edge to form a concave trough therein.
- a number of vanes 128 a, 128 b, 128 c may further extend between the upper buckle sidewalls 123 a, 123 b to hold the upper buckle sidewalls 123 a, 123 b together and maintain the desired separation distance.
- a grip wall 125 may be formed on and extend between the inner edges of the vanes 128 a, 128 b, 128 c .
- the surface of the grip wall 125 may be knurled, fluted, grooved, or otherwise tooled or formed with a surface treatment to provide a high friction or gripping surface against the upper strap 104 as further described herein.
- a pair of retention bulkheads 124 a, 124 b may extend normally inward from the interior sides of the upper buckle sidewalls 123 a, 123 b on an opposite end of the upper buckle 102 from the vanes 128 a, 128 b, 128 c .
- the retention bulkheads 124 a, 124 b define a gap 154 between them and thus do not extend as a single piece to connect the upper buckle sidewalls 123 a, 123 b together.
- the span 126 is thus positioned between the grip wall 125 connecting the vanes 128 a, 128 b, 128 c on one side and the retention bulkheads 124 a, 124 b on the other side.
- a span wall 138 may extend normally from a base of one edge of the span 126 on the side closest to the retention bulkheads 124 a, 124 b .
- a rear slot 150 is thereby defined between the span wall 138 and the retention bulkheads 124 a, 124 b .
- a front slot 152 is defined between a front edge of the span 126 and the grip wall 125 .
- the upper buckle bumper 140 may be formed of a thermoplastic elastomeric material, for example, rubber. In some embodiments the upper buckle bumper 140 may be formed as a separate piece and fitted onto the upper buckle body 122 . In other embodiments the upper buckle bumper 140 may be formed by an injection over mold process and directly molded onto the upper buckle body 122 . In the embodiments shown in FIGS. 2A, 2B, and 2C , the upper buckle bumper 140 is formed with two sidewall bumpers 142 a, 142 b connected together by a span bumper 144 .
- the sidewall bumpers 142 a, 142 b are sized and shaped to fit around an edge perimeter of the upper buckle sidewalls 123 a and 123 b .
- the span bumper 144 may be sized and configured to seat on top of the span 126 and connect the sidewall bumpers 142 a, 142 b together.

- the lower strap loop 109 is a permanent loop with opposing pieces of the lower strap 108 permanently fixed together, for example, by stitching, adhesive, or other fixation technique.
- the lower strap loop 109 could pass through the V-shaped slot 180 and then be threaded through one or both of the lower strap slots 186 a, 186 b in order to securely fasten the lower strap 108 to the handle link 116 .
- a steel D-ring 116 ′ as shown in FIG. 8B may be used in place of the handle link 116 in the rigging system 100 in order to increase the strength of the link structure connecting the handle strap 114 to the lower strap 108 .
- the D-ring 116 ′ may be formed of 6 mm- 8 mm diameter steel rod and bent into a triangular or D-shaped form as shown in FIG. 8B .

- the transverse ribs 194 a, 194 b on the cylindrical surface 192 of the handle core 190 form a structure that bites against the handle grip 198 to prevent the handle grip from sliding or spinning around the handle core 190 when gripped by a user.
- the end flanges 196 similarly resist longitudinal movement of the handle grip 198 along the handle core 190 .
- FIGS. 9A and 9B show the open ends of the handle core 190 as shown in FIGS. 9A and 9B .
- FIGS. 11A, 11B, and 11C show the structure of the end caps 200 in greater detail.

- the structure of the ankle strap 112 is depicted in greater detail in FIG. 12 .
- the ankle strap 112 is composed of an inner length of ankle web 220 that is surrounded, covered, or coated by a web cover 224 .
- the web cover 224 may be formed as a U-shaped stirrup with eye rings 226 on each end defining ring apertures 228 .
- the web cover 224 may be made of an elastomeric material, for example, rubber and encase a majority of the ankle web 220 . In one embodiment the web cover 224 may be over molded by injection molding over the ankle web 220 .
- the web cover 224 may be formed and define a seam 232 on an inner wall thereof to provide access for insertion of the ankle web 220 within the web slot 234 .
- the web cover 224 forms and exoskeleton over the ankle web 220 and supports the ankle strap 112 in a resilient form that, while pliable, is self-supporting and retains a stirrup shape that allows a user to more easily insert a foot through the opening.
- a middle length of the ankle web 220 extends through a sleeve portion 225 along the length of the web cover 224 .
- the two free ends of the ankle web 220 extend from the sleeve portion 225 of the web cover 224 out of web slots 234 into the ring apertures 228 defined by the eye rings 226 .
- a locking tab 230 may be formed as part of the web cover 224 and extend from the ankle strap rings 226 inward into the ring apertures 228 to form a semi-circular section opposite the free ends of the ankle web 220 .
- the free ends of the ankle web 220 may further be folded over in order to form web tabs 222 a, 222 b.
- the web tabs 222 a, 222 b seat within the upper band slot 206 and the lower band slot 208 of the end caps 200 .
- the web tabs 222 a, 222 b seat in the wider upper band slots and the end edges of the ankle web 220 abut the retention ledges 218 at the point of transition of thickness between the upper band slot 206 and the lower band slot 208 .
- the lengths of the ankle web 220 extending from the web tabs 222 a, 222 b extend through the thinner lower band slot 208 to exit the end caps 200 .
- the ankle strap rings 226 fit over and around the circumference of the cap heads 202 of the end caps 200 .
- the locking tabs 230 within the ring aperture 228 of the ankle strap ring 226 also seat within the upper band slots 206 above the web tabs 222 a, 222 b in order to ensure retention of the web tabs 222 a, 222 b within the end caps 200 .
- the ends of the ankle web 220 may be inserted through the lower band slot 208 and extended through the upper band slot 206 in the respective end caps 200 .
- the ends of the ankle web 200 may then be folded over to form the web tabs 222 a, 222 b which are sewn together.
- the web tabs 222 a, 222 b may then be pulled back into the upper band slot 206 to wedge the web tabs 222 a, 222 b within the upper band slot 206 against the retention ledge 218 .
- the web cover 224 may then be pried open along the cover seam 232 running length-wise along the middle and slipped over the ankle web 220 .
- the cap heads 202 of the end caps 220 may then be inserted into the ring apertures 228 at the lateral ends of the ankle strap 112 and the locking tabs 230 may be inserted into the upper band slots 206 .
- the ankle strap 112 may be removed from the handle 110 by pulling the end caps 200 out from their friction fit interface with the handle core 190 .
- the cap channels 214 and handle strap slots 210 and the end caps 200 align with the ends of the handle strap 114 exiting the handle core 190 .
- the cap channels 214 allow the handle strap 114 to be received within the cap sleeve 204 and ultimately seat within the handle strap slot 210 .
- the handle strap 114 fixes the ankle strap 112 in an obtuse angular position with respect to the longitudinal orientation of the handle strap and prevents the ankle strap from rotating with respect to the handle 110 .
- the interface between the locking tabs 230 and the upper band slots 206 and the end caps 200 prevent the ankle strap 112 from rotating with respect to the end caps 200 .
- the ankle strap 112 protrudes at a 120 degree angle from the vertical handle straps 114 (i.e., a plane containing an entire length of the ankle strap forms an angle of substantially 120 degrees with respect to the length of the first strap), thus extending the ankle strap 112 below the elevation of the handle 110 .
- This position allows a user to insert a foot through the ankle strap and under the handle 110 without having to use hands to hold the ankle strap 112 in place.
- the ankle strap 112 further radiates outward from a center axis of handle 110 (i.e., the ankle strap 112 extends in a plane containing a center axis of the tubular handle 110 when viewed from the side).
- the lateral protrusions of the end caps 200 and the ankle strap 112 beyond the separation distance of the handle strap 114 at the ends of the of the handle core 190 are very slight.
- This slim profile may be beneficial when doing exercises such as horizontal scissor kicks (i.e., essentially running in place horizontally, face down or face up with the foot straps on), because the user's feet can move in a more natural running movement without the handles 110 or ankle straps 112 hitting each other.
- the ankle strap 112 is removable, it may be desirable to provide a permanent attachment option in order to prevent removal and possible loss of the ankle strap 112 once removed.
- the cap sleeves 204 on the end caps 200 could be made without the cap channel 214 such that a tight friction fit of the end caps 200 in the handle core 190 would be achieved by wedging the handle strap 114 between the cap sleeves and the inner surface of the handle core 190 .
- cap sleeves 204 on the end caps 200 could again be made without the cap channel 214 , but the a perimeter of an area of the cap sleeve 204 conforming to the placement of the cap channel 214 on each end cap 200 could be scored or otherwise weakened such that a user could easily remove part of the cap sleeves 204 to create the cap channels 214 and thus convert otherwise fixed end caps into removable end caps 200 .
- the rigging system 100 may be mounted to a variety of fixed points in a number of different ways.
- the rigging system 100 may be mounted to a fixed-point mount 260 such as shown in FIG. 1A .
- the fixed-point mount 260 may hold a steel pin 264 , preferably in a horizontal orientation.
- a mount strap 262 may loop around the steel pin 264 and provide a connection loop end 266 freely hanging from the steel pin 264 .
- connection loop end 266 may be fitted around the retention bulkheads 124 a, 124 b of the upper buckle 102 by slipping an edge of the web of the connection loop end 266 through the gap 154 between the retention bulkheads 124 a, 124 b to place the part of connection loop end 266 in the rear slot 150 and around the retention bulkheads 124 a, 124 b .
- the rigging system 100 may be held from the fixed point mount 260 by the interface between the mount strap 262 and the retention bulkheads 124 a, 124 b as shown in FIG. 1A .
- the rigging system 100 may be mounted directly to any, preferably mostly cylindrical, bar 268 or post at any orientation as indicated in FIG. 10 .
- the upper strap 104 may be removed from the front slot 152 , wrapped around the bar 268 , and then threaded back through the front slot 152 and pulled tight such that around the bar 268 .
- the upper strap restraint 118 at the free end of the upper strap 104 is highly pliable and can easily be inserted through the front slot 152 in either direction.
- the concave trough formed in the upper buckle span 126 generally conforms to the curvature of the bar 268 .
- the loop formed between the two lengths of the upper strap 104 extending above the upper buckle 102 similarly wrap around and conform to the bar 268 to hold the rigging system snugly in position.
- the upper buckle clip 130 firmly biases the upper strap 104 against the grip wall 125 in the front slot 152 preventing the upper strap 104 from slipping or loosening.
- the span bumper 144 covering the span 126 and the sidewall bumpers 142 a, 142 b adjacent the span bumper 144 provide a high-friction, non-slip surface that further prevents slippage of the upper buckle 102 with respect to the bar 268 and holds the rigging system in a fixed point position.
- the rigging system 100 may be mounted in a doorjamb not shown) to provide a fixed point mounting location.
- the upper strap 104 may be pulled tight against the span 126 , thereby removing the loop from the prior configuration that fit around the bar 268 .
- the upper buckle 102 may then be positioned on one side of a door, both lengths of the upper strap 104 extending from the upper buckle 102 may be placed over the top of the door, and the door may be closed against the door jamb such that the lengths of the upper strap 104 extend through the crack between the door and the door jamb.
- the upper buckle 102 may be oriented on the opposite side of the door such that the flat, bottom edge of the upper buckle 102 seats against the door and the door jamb, thus preventing the upper strap 104 from pulling through the crack.
- the rubber sidewall bumpers 142 a, 142 b provide both a non-slip surface and a non-scuff surface against the door and the door jamb, thereby preventing damage to the door and frame when a door is used as a fixed point anchor for the rigging system 100 in this manner.
- the user to change its length to accommodate for the height of the fixed point, the size of the user, the type of exercise to be performed, or any combination of these needs may easily adjust the rigging system 100 .
- the primary adjustment to a length of the rigging system 100 may be made using the lower buckle 108 .
- the lower strap 108 can freely slide within the lower slot 164 around the lower buckle bulkhead 161 , thus changing the distance between the lower buckle 108 and the handle 110 .
- the lower buckle 108 can remain a pre-determined distance from the upper buckle 102 while changing the location of the handle 110 relative to the fixed-point mount.
- the lower buckle 108 can remain at a predetermined distance from the fixed-point mount during adjustment of a vertical position of the handle 110 .
- this predetermined distance between the upper buckle 102 and lower buckle 108 can be selectively changed by adjusting the distance between the lower buckle 108 and the upper buckle 102 using the adjustment feature of the upper buckle clip 130 .
- the paddle may be released, allowing the torsion spring 174 on the lower buckle 106 to bias the grip surface on the lower buckle clip 170 toward the grip wall 165 and pressing against the lower strap 108 to hold it there between.
- the lower strap restraint 120 may be used to hold the free end of the lower strap 108 against the length of lower strap 108 under tension in order to avoid possible interference of the free end of the lower strap 108 with the user when performing exercises.
- the lower strap restraint 120 may be a length of hook and loop fastener material affixed to the free end of the lower strap 108 that extends laterally to form tab structures. The tabs may be long enough to fold around the width of the opposing length of the lower strap 108 and hook together around the portion of the lower strap 108 under tension.
- the length of the upper strap 104 can likewise be adjusted in combination.
- the upper buckle clip 130 can be manipulated to release the bias force on the upper strap 104 , allowing the length to be adjusted to a new position, which changes the distance between the lower buckle 104 and the upper buckle 102 .
- the upper buckle clip 130 can be released after appropriate adjustment of the upper strap 104 to reassert the bias force of the upper buckle clip 130 on the upper strap 104 to hold it firmly in position.
- the upper strap restraint 118 may be used to hold the free end of the upper strap 104 against the length of upper strap 104 under tension in order to avoid possible interference of the free end of the upper strap 104 with the user when performing exercises.
- the upper strap restraint 118 may be a length of hook and loop fastener material affixed to the free end of the upper strap 104 that extends laterally to form tab structures. The tabs may be long enough to fold around the width of the opposing length of the upper strap 104 and hook together around the portion of the upper strap 108 under tension.
- the free ends of the upper strap 104 and lower strap 108 are less likely to interfere with the user when performing an exercise. For example, if the lower buckle 106 was located adjacent to the handle straps 114 rather than the handle link 116 , the free end of the lower strap 108 would fall downward toward the handle 110 and ankle strap 112 and possibly interfere with the user when performing exercises. By placing the lower buckle 106 away from a connection point with the handle straps 114 , the likelihood of the free end of the lower strap 108 interfering with the handle 110 or the ankle strap 112 is averted or minimized. Positioning the lower buckle 106 away from connection adjacent to the handle straps 114 also prevents the possibility of discomfort of the lower buckle 106 pressing into a user's forearm when performing exercises.
- FIG. 14 depicts an alternate embodiment of a rigging system for suspension exercise training in which the lower strap 108 is provided with a series of measurement markers 240 spaced along the length of the lower strap 108 .
- the measurement markers 240 may be positioned at even increments of a particular unit of measure (for example, inches).
- the measurement markers 240 may be marks woven within the web of the lower strap 108 , marks screen printed onto the web of the lower strap 108 , labels adhered or sewn to the web of the lower strap 108 , or formed on the lower strap 108 in any other fashion. As shown in FIG.
- the lower buckle may be formed with a recess in the lower buckle bulkhead 161 that creates a marker window 176 to frame or highlight the present selected measurement on the lower strap 108 .
- a measurement system may be a significant aid to the user when changing a length of the lower strap 108 to accommodate different exercises during an exercise program.
- FIG. 15 depicts an alternate embodiment of a rigging system for suspension exercise training, wherein two separate rigging systems 100 are used in conjunction and connected together by a connector bar 250 .
- the ankle straps 112 are removed from the handles 110 on each of the rigging systems 100 .
- the connector bar 250 may then be connected between two opposing ends of the handles 110 ; for example, by use of friction fit inserts (not shown) extending from the connector bar 250 into the handle cores 190 of each of the handles 110 .
- Such a configuration may provide a user with an alternate rigging system for the performance of different exercises.
- the wider handle surface provided by the connector bar 250 may provide a simplified or easier platform for users new to suspension exercise training to complete appropriate exercises.

Abstract
Description
- This application claims, under 35 U.S.C. §119(e), the benefit of U.S. Provisional Patent Application No. 62/352,372, filed on Jun. 20, 2016, entitled “Rigging System for Suspension Exercise Training,” which application is hereby incorporated by reference in its entirety.
- The technology described herein relates to a rigging system for suspension exercise training.
- Suspension exercise training is a form of bodyweight resistance exercise using a rigging system with ropes or straps to support the user while performing a variety of movements to increase strength and flexibility. Various forms of rigging systems have been designed to aid a user in performing suspension exercises. The rigging systems need to be able to attach to a fixed point above the user and be strong enough to support the user's weight plus additional force caused by the user when pulling on or moving while supported by the rigging system. Rigging systems for suspension exercise training also often include handles for ease of holding and grasping the device opposite the fixed end. The straps, cords, or ropes used in such rigging systems are often adjustable to accommodate different heights and relative locations for fixed points and different sizes of users. Due to the desire for adjustability, design challenges arise. For example, excess strap length can impede the user when performing an exercise. Further, connection to different types of fixed points can require multiple additional attachment components.
- The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded subject matter by which the scope of the invention as defined in the claims is to be bound.
- In one implementation, a rigging system is disclosed for use in performing suspension exercises. The rigging system includes a first strap, an first buckle, and a handle. The first buckle forms a distal end of the rigging system through which a first end portion of the first strap is threaded and in which the first strap is selectively secured. The first buckle further includes a first buckle body including a span and two sidewalls positioned on opposing sides of the span and connected to the span. The sidewalls are defined by respective perimeter edges. A resilient bumper surface is formed on the perimeter edges of the sidewalls. A retention structure is joined to the body that releasably secures the first strap within and with respect to the first buckle at a variety of positions. A handle is operatively associated with a second end of the first strap.
- In another implementation, a rigging system is disclosed for use in performing suspension exercises. The rigging system includes a first strap and a second strap connected to each other by a lower buckle. A handle is further connected to an end of the second strap by a third strap. The lower buckle is connected to a first end of the first strap. The lower buckle includes a lower buckle body that defines a slot through which the second strap passes and a bulkhead around which the second strap loops whereby a length of the second strap is located below a length of the first strap when a second end of the first strap is joined to a fixed point located above the second strap such that the first and second straps hang vertically from the fixed point. A retention structure is joined to the lower buckle body that releasably secures the second strap within and with respect to the lower buckle at a variety of positions. The third strap is connected at both ends to an end of the second strap. The handle is supported by a length of a portion of the third strap.
- In a further implementation, a rigging system is disclosed for use in performing suspension exercises. The rigging system includes a first strap of a first length; a second may strap of a second length, a first buckle, a second buckle, and a handle. The first buckle may form a distal end of the rigging system through which the first length of the first strap is selectively secured. The second strap may be fixed at a first end to a first end of the first strap. The second length of the second strap is thus located below the first length of the first strap when a portion of the first strap between the first end and a second end is joined to a fixed point located above the second strap such that the first and second straps hang vertically from the point. The second length of the second strap may be selectively secured through the second buckle. The handle may be connected to a second end of the second strap in a fixed position such that a distance between second end of the second strap and the handle is constant.
- In yet another implementation, a rigging system is disclosed for use in performing suspension exercises. The rigging system includes a first strap of a first length, a second strap of a second length connected to an end of the first strap, an elongate handle, and an ankle strap. The elongate handle may be connected to the second strap in an orientation normal to the first length of the first strap when the first strap is under tension. The ankle strap is formed as a resilient, self-supporting stirrup connected to the elongate handle, wherein lateral ends of the ankle strap are connected to lateral ends of the elongate handle.

FIG. 15 is an isometric view of an alternate embodiment including two rigging systems without ankle straps and further including a connector bar that connects the handles of the two rigging systems together. - Various embodiments of a rigging system for use in performing suspension exercises are disclosed herein. The rigging system is configured for selective attachment to a fixed-point mount (e.g., a beam, a bar, a tree limb, or a door jamb), typically located at a position above the user's head. A handle on the opposite end of the rigging system hangs from this fixed point and is grasped by the user to support a portion of the user's weight while the user performs resistance exercises against a reduced portion of the user's body weight. In some embodiments, the fixed point may be a doorjamb above the top of a door. In the disclosed embodiments, a height adjustment buckle of the rigging system is designed to be positioned generally distal from a structure forming the handle during use of the rigging system. This is in contrast to other suspension exercise trainers in which the adjustment buckle is fixedly joined to the handle structure, thus locating the buckle in a position generally closer to the forearm during use of the rigging system. There are some potential downsides to this position. First, the height adjustment buckle can press against the arm, which is uncomfortable. Second, adjusting the handle up and down becomes a two-step process, because after adjusting the height, the user must then manage the excess webbing to minimize interference of the webbing with the user's motion during a training exercise. By positioning the height adjustment buckle in a selectively changeable position that is typically away from the handle straps, the free end of the strap extending away from the height adjustment buckle will generally not come into contact with the user during the exercise. Since the excess webbing at the free end of the strap may be allowed to hang down freely during an exercise as it will generally not interfere with the user's motion, it does not need to be adjusted separately.
- An upper buckle, which may also be referred to as a height adjustment buckle, can serve as a door anchor, or can cinch over a pull-up bar. A rubber outside edge helps to protect the doorframe from damage, and helps to grip a pull-up bar when cinched tight. The upper buckle also provides adjustability for positioning the lower buckle, allowing easy access for people of different heights, or for different ceiling heights.

FIGS. 1A, 1B, and 1C depict an embodiment of a riggingsystem 100 for exercise training. Primary components of the riggingsystem 100 may include anupper buckle 102, anupper strap 104, alower buckle 106, alower strap 108, ahandle 110, anankle strap 112, ahandle strap 114, and ahandle link 116. Theupper strap 104 joins theupper buckle 102 to thelower buckle 106. An end portion of theupper strap 104, which for convenience may be referred to herein as the first end portion of theupper strap 104, may be threaded through theupper buckle 102 and adjustably engaged therewith. Another end portion of theupper strap 104, which for convenience may be referred to herein as the second end portion of theupper strap 104, may be connected to thelower buckle 106 preferably via aloop 105 formed in the second end of theupper strap 104 extending around a structure of thelower buckle 106. Theloop 105 in theupper strap 104 may be fixed in size and position as shown or it may alternatively be adjustable as further described herein. - The
upper buckle 102 may be attached to an optional fixed-point mount 260 via amount strap 262 as further described below. Theupper buckle 102 may also be attached to other fixed-point structures (e.g., bars, tree limbs, poles, etc.) via themount strap 262, another strap, or theupper strap 104. Alternatively, theupper buckle 102 may provide a resistance stop for placement between a door and a doorjamb and function as the fixed point. A first end portion of thelower strap 108 may be adjustably connected to thelower buckle 106 on an opposite side of thelower buckle 106 from the attachment of theupper strap loop 105. A second end portion of thelower strap 108 may be attached to thehandle link 116. In one embodiment thelower strap 108 has a fixed connection to thehandle link 116 via aloop 109. In other embodiments theloop 109 may be adjustable as further described herein below. - A first end portion of the
handle strap 114 may be connected to thehandle link 116 via ahandle strap loop 115 a formed in the first end. A similarhandle strap loop 115 b may be formed in a second end portion of thehandle strap 114 to similarly connect the second end to thehandle link 116. A middle section of thehandle strap 114 supports or otherwise connects to thehandle 110 as further described herein. Theankle strap 112 also attaches to thehandle 110 and may be attached in a fixed position relative to thehandle 110 as further described herein. - The
upper buckle 102 is shown in greater detail from multiple perspectives inFIGS. 2A-4C . Theupper buckle 102 may be constructed around anupper buckle body 122 that provides a framework for other components of theupper buckle 102. Theupper buckle body 122 may be a monolithic piece formed of plastic, e.g., by injection molding. In exemplary embodiments, the plastic may be a high strength, abrasion and impact resistant, thermoplastic polyamide (nylon) formulation (e.g., Zytel® 43% glass-filled nylon to 30% glass-filled nylon, or carbon-filled nylon). Other subcomponents of theupper buckle 102 or other plastic components of theriggings system 100 such as thelower buckle 106, thehandle link 116, and thehandle 110 may be made of the same or similar plastics with similar qualities. In alternate embodiments, theupper buckle body 122 may be formed from a stamped metal such as aluminum. In other embodiments, theupper buckle body 122 and other components of theupper buckle 102 may be made of die cast steel to increase the strength of such components. Other components (e.g., thelower buckle 106 and the handle link 116) may be similarly formed. - The
upper buckle body 122 may have opposingsidewalls upper buckle span 126 which holds the upper buckle sidewalls 123 a, 123 b in a position spaced apart from each other. The upper buckle sidewalls 123 a, 123 b may be formed as oval or oblong shapes as shown in the embodiments ofFIGS. 2A-2C . However, the upper buckle sidewalls 123 a, 123 b may be formed in various other shapes as desired. In the exemplary embodiment shown, the top edges of the upper buckle sidewalls 123 a, 123 b may be formed with corresponding symmetric depressions in positions adjacent to span 126. Similarly, thespan 126 may be contoured from a front edge to a back edge to form a concave trough therein. In addition to theupper buckle span 126, a number ofvanes - A
grip wall 125 may be formed on and extend between the inner edges of thevanes grip wall 125 may be knurled, fluted, grooved, or otherwise tooled or formed with a surface treatment to provide a high friction or gripping surface against theupper strap 104 as further described herein. A pair ofretention bulkheads upper buckle 102 from thevanes retention bulkheads gap 154 between them and thus do not extend as a single piece to connect the upper buckle sidewalls 123 a, 123 b together. Thespan 126 is thus positioned between thegrip wall 125 connecting thevanes retention bulkheads - A
span wall 138 may extend normally from a base of one edge of thespan 126 on the side closest to theretention bulkheads rear slot 150 is thereby defined between thespan wall 138 and theretention bulkheads front slot 152 is defined between a front edge of thespan 126 and thegrip wall 125. - A number of the surfaces of the
upper buckle 102 may be covered or coated with anupper buckle bumper 140. Theupper buckle bumper 140 may be formed of a thermoplastic elastomeric material, for example, rubber. In some embodiments theupper buckle bumper 140 may be formed as a separate piece and fitted onto theupper buckle body 122. In other embodiments theupper buckle bumper 140 may be formed by an injection over mold process and directly molded onto theupper buckle body 122. In the embodiments shown inFIGS. 2A, 2B, and 2C , theupper buckle bumper 140 is formed with twosidewall bumpers span bumper 144. Thesidewall bumpers span bumper 144 may be sized and configured to seat on top of thespan 126 and connect thesidewall bumpers upper buckle bumper 140 may also be formed to follow the depressions in the upper buckle sidewalls 123 a, 123 b and the concave form of thespan 126 to provide acontour surface 146 along the length of thespan 126 and through to the outer surfaces of the upper buckle sidewalls 123 a, 123 b. - As shown in
FIGS. 3, 4A, 4B, and 4C , a top surface of thespan 126 may define a number ofgrooves 127. A bottom surface of thespan bumper 144 may be formed with a number ofbumper ribs 148 sized, spaced, and configured to seat within theretention grooves 127 on the top surface of thespan 126. Similarly theupper buckle body 122 may be formed with a pair ofgrooves 147 that are inset from and follow the perimeter of the upper buckle sidewalls 123 a, 123 b. Thesidewall bumpers lips 145 on outer and inner edges in order to define achannel 143 there between. Thus when theupper buckle bumper 140 is placed on theupper buckle body 122, aninner lip 145 of each of thesidewall bumpers grooves 147 in theupper buckle body 122; theouter lips 145 of each of thesidewall bumpers channels 143 in thesidewall bumpers upper buckle bumper 140 securely attaches to and is held in place on theupper buckle body 122. - An
upper buckle clip 130 is retained within theupper buckle body 122 by ashaft 132. Theupper buckle clip 130 is shown to best advantage inFIGS. 4A, 4B, and 4C and may be made of the same material as theupper buckle body 122. Theupper buckle clip 130 may include apaddle portion 156 that extends from a number ofhinge bosses 160 arranged adjacent to and separated from each other along a width of theupper buckle clip 130. Agrip surface 158 may be formed on theupper buckle clip 130 opposite thehinge bosses 160. Thegrip surface 158 may be knurled, notched, grooved, fluted, or provided with any other appropriate high friction surface texture or feature. Each of thehinge bosses 160 may define ahinge aperture 162 arranged along a common center axis. The hinge apertures 162 may be sized to receive aclip shaft 132. - A
torsion spring 134 may seat between two of thehinge bosses 160 such that theclip shaft 132 additionally passes through a center of the windings of thetorsion spring 134. A pair ofspring arms torsion spring 134 and define a separation angle between them. Afirst spring arm 136 a may seat within an aperture in thepaddle 156. Thesecond spring arm 136 b may seat within anotch 139 formed within a bottom edge of thespan wall 138. A pair ofshaft apertures 129 may be defined within the upper buckle sidewalls 123 a, 123 b below the front edge of thespan 126. Theshaft apertures 129 may be sized to receive theclip shaft 132. Theupper buckle clip 130 may thus be positioned within a well in theupper buckle body 122 beneath thespan 126 with theclip shaft 132 extending through theshaft aperture 129 in the firstupper buckle sidewall 123 a, then through thehinge apertures 162 and thehinge bosses 160 of theupper buckle clip 130, including through thespring 134, and then extending through theshaft aperture 129 in the secondupper buckle sidewall 123 b to hold theupper buckle clip 130 in place in theupper buckle body 122. Theupper buckle clip 130 may be arranged such that thegrip surface 158 on theupper buckle clip 130 is positioned opposite thegrip wall 125 of theupper buckle body 122. - As shown in
FIGS. 1A, 1B, 10 andFIG. 3 , theupper strap 104 is releasably engaged within theupper buckle 102 and connects theupper buckle 102 to thelower buckle 106. The upper strap 102 (as well as all of the other straps forming embodiments of the riggingsystem 100 disclosed herein) may be formed of webbing, for example, 38 mm nylon or nylon-polypropylene webbing with test strengths between 1300 lb. and 2000 lb. or greater. In other embodiments, the webbing may include a Kevlar® weave for added tensile strength and durability. A first end of theupper strap 104 may be arranged in theupper buckle 102 with one length of theupper strap 104 positioned in therear slot 150 between theretention bulkheads span wall 138. Theupper strap 104 may fold on itself to create a loop above thespan 126 and direct a second length of theupper strap 104 through thefront slot 152 and between thegrip wall 125 and thegrip surface 158 on theupper buckle clip 130. A free end of theupper strap 104 may extend from thefront slot 152 beneath theupper buckle 102 parallel and adjacent to an opposing length of theupper strap 104. Anupper strap restraint 118 may be attached to the free end of theupper strap 104 in order to secure the free end of theupper strap 104 to the length of theupper strap 104 extending between theupper buckle 104 and thelower buckle 106. - As shown in
FIGS. 5A-6C , thelower buckle 106 may connect theupper strap 104 to thelower strap 108. Thelower buckle 106 may be formed in a similar manner as theupper buckle 102 whereby two lower buckle sidewalls 163 a, 163 b are spaced apart from each other in parallel and are held together by alower buckle bulkhead 161 and alower buckle span 167. Note, in the case of thelower buckle 106, thelower buckle bulkhead 161 is a single piece and extends entirely between the lower buckle sidewalls 163 a, 163 b. An interior wall of thelower buckle bulkhead 161 is formed as agrip wall 165 similar in form to thegrip wall 125 of theupper buckle 102. Thegrip wall 165 is spaced apart from an edge of thelower buckle span 167 thereby defining alower slot 164 there between. Ahasp portion 159 is formed between the lower buckle sidewalls 163 a, 163 b on an opposite end of thelower buckle 106 from thelower buckle bulkhead 161. Thehasp portion 159 defines aretention slot 168 there through. Anupper slot 166 is further defined between thehasp portion 159 and thelower buckle span 167. Aspan wall 178 extends downward from an edge of thelower buckle span 167 to further define theupper slot 166 in a similar manner as thespan wall 138 of theupper buckle 102. Aspring arm notch 179 is formed within a bottom edge of thespan wall 138. - Two
shaft apertures 169 are defined, respectively, within the lower buckle sidewalls 163 a, 163 b substantially below thelower buckle span 167. Alower buckle clip 170 that is identical in form to theupper buckle clip 130 seats within a well in thelower buckle 106 beneath thelower buckle span 167 and pivots on alower buckle shaft 172 that seats within theshaft apertures 169 in the lower buckle sidewalls 163 a, 163 b. A lowerbuckle torsion spring 174 also seats around theshaft 172 to bias the lower buckle clip against thegrip wall 165. As noted, the form of thelower buckle clip 170 and its configuration within thelower buckle 106 are substantially the same as the form and configuration of theupper buckle clip 130 and, therefore, the description above with respect to theupper buckle 102 is equally applicable with respect to thelower buckle 106 and no further description need be provided. - The
upper strap 104 passes through theupper slot 166 and wraps around thehasp portion 159 to form anupper strap loop 105 and connect to thelower buckle 106. In some embodiments, theupper strap loop 105 may have a fixed connection such that two opposing portions of the upper strap are sewn, adhered, or otherwise fixed to each other in order to form a permanent loop. In other embodiments anupper strap loop 105 may be formed by passing a free end of theupper strap loop 105 through theupper slot 166 and then passing the free end through theretention slot 168 to create a loop that cinches theupper strap 104 to thehasp portion 159 of thelower buckle 106. Thelower strap 108 may pass through thelower slot 164 defined between thelower buckle bulkhead 161 and thelower buckle span 167 and pass between a grip surface of thelower buckle clip 170 and thegrip wall 165 on the interior side of thelower buckle bulkhead 161. Thetorsion spring 174 may hold thelower buckle clip 170 in a biased position to pinch thelower strap 108 against thegrip wall 165. Alower strap restraint 120 may be attached to the free end of thelower strap 106 in order to secure the free end of thelower strap 106 to the length of thelower strap 106 extending between thelower buckle 106 and thehandle link 116. - As shown in
FIGS. 1A, 1B, 1C , a lower portion of thelower strap 108 extends downward and terminates at alower strap loop 109 that is secured around ahandle link 116. As shown inFIG. 8A , thehandle link 116 may be a monolithic piece (e.g., an injection molded plastic part or a stamped metal piece) defining atop bar 182 connected to a V-shapedbar 184 and defining a V-shapedslot 180 there between. Thetop bar 182 may further define twolower strap slots bar 184 may further define two pairs (i.e., four total) handlestrap slots bar 184 and two adjacent slots are formed in the second leg of the V-shapedbar 184. In one embodiment thelower strap 108 passes through the V-shapedslot 180 and wraps around thetop bar 182 to form thelower strap loop 109 connected to thehandle link 116. In the exemplary embodiment shown, thelower strap loop 109 is a permanent loop with opposing pieces of thelower strap 108 permanently fixed together, for example, by stitching, adhesive, or other fixation technique. In an alternative embodiment, thelower strap loop 109 could pass through the V-shapedslot 180 and then be threaded through one or both of thelower strap slots lower strap 108 to thehandle link 116. - In an alternate embodiment, a steel D-
ring 116′ as shown inFIG. 8B may be used in place of thehandle link 116 in the riggingsystem 100 in order to increase the strength of the link structure connecting thehandle strap 114 to thelower strap 108. The D-ring 116′ may be formed of 6mm-8mm diameter steel rod and bent into a triangular or D-shaped form as shown inFIG. 8B . The bent rod material may form a straighttop bar 182′ and a bent or V-shapedbar 184′ beneath thetop bar 182′ and thereby define atriangular slot 180′. Thelower strap loop 109 would wrap around thetop bar 182′ and thehandle strap loops bar 184′. - As shown in
FIG. 7 , thehandle strap 114 extends downward from thehandle link 116 to connect with thehandle 110 and theankle strap 112. The free ends of thehandle strap 114 may be passed through the V-shapedslot 180 and around respective legs of the V-shapedbar 184 in order to formhandle strap loops handle strap 114 to thehandle link 116. Thehandle strap loops bar 184 positioned within thehandle strap loops slot 180 in thehandle link 116 and then threaded through one or both of the slots in respective pairs ofhandle strap slots - Before the
handle strap 114 is secured to thehandle link 116, thehandle strap 114 passes through a core of thehandle 110 as depicted inFIGS. 9A and 9B . Thehandle 110 may be composed of several components including ahandle core 190, ahandle grip 198, and twoopposing end caps 200.FIG. 10 depicts the construction of thehandle core 190 in greater detail. As shown inFIG. 10 , thehandle core 190 is formed as a cylindrical tube of generally constant diameter. Each of the lateral ends of thehandle core 190 flare outward circumferentially to formend flanges 196. A grid oftransverse ribs outer surface 192 of thehandle core 190. Thehandle core 190 and the features thereof may be formed monolithically, for example, by a plastic injection molding process. Thehandle grip 198 may be formed on thehandle core 190 by overmolding an elastomeric material. Theend flanges 196 may provide a boundary to the spread of the elastomeric material as it cures and thetransverse ribs handle core 190. - In another implementation, the
handle grip 198 may be sleeved over thehandle core 190 and seat between theend flanges 196. In this implementation, thehandle grip 198 may be formed as a tube of a foam or elastomeric material to provide a cushioned grip to the user. Thetransverse ribs cylindrical surface 192 of thehandle core 190 form a structure that bites against thehandle grip 198 to prevent the handle grip from sliding or spinning around thehandle core 190 when gripped by a user. Theend flanges 196 similarly resist longitudinal movement of thehandle grip 198 along thehandle core 190. - The open ends of the
handle core 190 are covered byend caps 200 as shown inFIGS. 9A and 9B .FIGS. 11A, 11B, and 11C show the structure of the end caps 200 in greater detail. Each of the end caps 200 has acap head 202 on one end and acap sleeve 204 that extends from an inside base surface of thecap head 202. Thecap head 202 may be formed as a circular disc of a diameter commensurate with the diameter of theend flanges 196 of thehandle core 190. Thecap sleeve 204 may be of smaller diameter than thecap head 202 and have an outer diameter generally congruent with an inner diameter of thehandle core 190 in order to provide a friction fit between thecap sleeve 204 and an inner wall of thehandle core 190. - The
cap head 202 may define anupper band slot 206 and alower band slot 208 that align with each other within thecap head 202 to define a continuous passageway there through. The thickness of thelower band slot 208 may be greater than the thickness of theupper band slot 206 such that aretention ledge 218 is formed as a step between theupper band slot 206 and thelower band slot 208 in the middle of thecap head 202. The cylindrical wall forming thecap sleeve 204 defines acap cavity 212 and an interior side of thecap head 202 forms a base of thecap cavity 212. Acap channel 214 is formed in a portion of the sidewall of thecap sleeve 204. Ahandle strap slot 210 is formed in a portion of thecap head 202 axially offset from the positions of theupper band slot 206 and thelower band slot 208 and adjacent the interior wall of thecap head 202 forming the base of thecap cavity 212. Thehandle strap slot 210 is wider than and is centered on thecap channel 214 such that thecap channel 214 and thehandle strap slot 210 form a continuous T-shaped opening. - A
guide wall 216 is formed as a cord panel within thecap cavity 212 extending normally from the interior base wall of thecap head 202 and parallel to the opening defined by thecap channel 214. Theguide wall 216 may extend for only a portion of the length of thecap sleeve 204 as depicted in the figures or it may extend the entire length of thecap sleeve 204 in other embodiments not shown. A middle portion of the handle strap extends through thehandle core 190 and further through thecap cavities 212 of each of the end caps 200 adjacent theguide walls 216 to exit out of thehandle strap slots 210 and extend upward toward thehandle link 116 as show inFIGS. 9A and 9B . - The structure of the
ankle strap 112 is depicted in greater detail inFIG. 12 . Theankle strap 112 is composed of an inner length ofankle web 220 that is surrounded, covered, or coated by aweb cover 224. Theweb cover 224 may be formed as a U-shaped stirrup with eye rings 226 on each end definingring apertures 228. Theweb cover 224 may be made of an elastomeric material, for example, rubber and encase a majority of theankle web 220. In one embodiment theweb cover 224 may be over molded by injection molding over theankle web 220. In another embodiment theweb cover 224 may be formed and define aseam 232 on an inner wall thereof to provide access for insertion of theankle web 220 within theweb slot 234. By this sleeved or over molded construction, theweb cover 224 forms and exoskeleton over theankle web 220 and supports theankle strap 112 in a resilient form that, while pliable, is self-supporting and retains a stirrup shape that allows a user to more easily insert a foot through the opening. - A middle length of the
ankle web 220 extends through asleeve portion 225 along the length of theweb cover 224. The two free ends of theankle web 220 extend from thesleeve portion 225 of theweb cover 224 out ofweb slots 234 into thering apertures 228 defined by the eye rings 226. Alocking tab 230 may be formed as part of theweb cover 224 and extend from the ankle strap rings 226 inward into thering apertures 228 to form a semi-circular section opposite the free ends of theankle web 220. The free ends of theankle web 220 may further be folded over in order to formweb tabs - As depicted in
FIG. 9B , theweb tabs upper band slot 206 and thelower band slot 208 of theend caps 200. Theweb tabs ankle web 220 abut theretention ledges 218 at the point of transition of thickness between theupper band slot 206 and thelower band slot 208. The lengths of theankle web 220 extending from theweb tabs lower band slot 208 to exit theend caps 200. The ankle strap rings 226 fit over and around the circumference of the cap heads 202 of theend caps 200. The lockingtabs 230 within thering aperture 228 of theankle strap ring 226 also seat within theupper band slots 206 above theweb tabs web tabs end caps 200. - To assemble the
ankle strap 112 with the sleeved form of theweb cover 224 and connect it to thehandle 110, the ends of theankle web 220 may be inserted through thelower band slot 208 and extended through theupper band slot 206 in therespective end caps 200. The ends of theankle web 200 may then be folded over to form theweb tabs web tabs upper band slot 206 to wedge theweb tabs upper band slot 206 against theretention ledge 218. Theweb cover 224 may then be pried open along thecover seam 232 running length-wise along the middle and slipped over theankle web 220. The cap heads 202 of the end caps 220 may then be inserted into thering apertures 228 at the lateral ends of theankle strap 112 and the lockingtabs 230 may be inserted into theupper band slots 206. - As depicted in
FIG. 13 , theankle strap 112 may be removed from thehandle 110 by pulling the end caps 200 out from their friction fit interface with thehandle core 190. As may be understood when viewingFIG. 13 in combination withFIG. 9B , when the ankle straps 112 are connected to thehandle 110, thecap channels 214 and handlestrap slots 210 and the end caps 200 align with the ends of thehandle strap 114 exiting thehandle core 190. Thecap channels 214 allow thehandle strap 114 to be received within thecap sleeve 204 and ultimately seat within thehandle strap slot 210. It should also be noted that once thehandle strap 114 seats within thehandle strap slot 210, thehandle strap 114 fixes theankle strap 112 in an obtuse angular position with respect to the longitudinal orientation of the handle strap and prevents the ankle strap from rotating with respect to thehandle 110. Similarly the interface between the lockingtabs 230 and theupper band slots 206 and the end caps 200 prevent theankle strap 112 from rotating with respect to theend caps 200. - In one exemplary embodiment, the
ankle strap 112 protrudes at a 120 degree angle from the vertical handle straps 114 (i.e., a plane containing an entire length of the ankle strap forms an angle of substantially 120 degrees with respect to the length of the first strap), thus extending theankle strap 112 below the elevation of thehandle 110. This position allows a user to insert a foot through the ankle strap and under thehandle 110 without having to use hands to hold theankle strap 112 in place. Theankle strap 112 further radiates outward from a center axis of handle 110 (i.e., theankle strap 112 extends in a plane containing a center axis of thetubular handle 110 when viewed from the side). Additionally, the lateral protrusions of the end caps 200 and theankle strap 112 beyond the separation distance of thehandle strap 114 at the ends of the of thehandle core 190 are very slight. This slim profile may be beneficial when doing exercises such as horizontal scissor kicks (i.e., essentially running in place horizontally, face down or face up with the foot straps on), because the user's feet can move in a more natural running movement without thehandles 110 orankle straps 112 hitting each other. - While in the exemplary embodiment shown in the figures the
ankle strap 112 is removable, it may be desirable to provide a permanent attachment option in order to prevent removal and possible loss of theankle strap 112 once removed. In one embodiment, thecap sleeves 204 on the end caps 200 could be made without thecap channel 214 such that a tight friction fit of the end caps 200 in thehandle core 190 would be achieved by wedging thehandle strap 114 between the cap sleeves and the inner surface of thehandle core 190. In another exemplary embodiment,cap sleeves 204 on the end caps 200 could again be made without thecap channel 214, but the a perimeter of an area of thecap sleeve 204 conforming to the placement of thecap channel 214 on eachend cap 200 could be scored or otherwise weakened such that a user could easily remove part of thecap sleeves 204 to create thecap channels 214 and thus convert otherwise fixed end caps intoremovable end caps 200. - As noted above the rigging
system 100 may be mounted to a variety of fixed points in a number of different ways. In one implementation, the riggingsystem 100 may be mounted to a fixed-point mount 260 such as shown inFIG. 1A . The fixed-point mount 260 may hold asteel pin 264, preferably in a horizontal orientation. Amount strap 262 may loop around thesteel pin 264 and provide aconnection loop end 266 freely hanging from thesteel pin 264. Theconnection loop end 266 may be fitted around theretention bulkheads upper buckle 102 by slipping an edge of the web of theconnection loop end 266 through thegap 154 between theretention bulkheads connection loop end 266 in therear slot 150 and around theretention bulkheads system 100 may be held from the fixedpoint mount 260 by the interface between themount strap 262 and theretention bulkheads FIG. 1A . - In an alternative configuration, the rigging
system 100 may be mounted directly to any, preferably mostly cylindrical,bar 268 or post at any orientation as indicated inFIG. 10 . Theupper strap 104 may be removed from thefront slot 152, wrapped around thebar 268, and then threaded back through thefront slot 152 and pulled tight such that around thebar 268. Theupper strap restraint 118 at the free end of theupper strap 104 is highly pliable and can easily be inserted through thefront slot 152 in either direction. In this configuration, the concave trough formed in theupper buckle span 126 generally conforms to the curvature of thebar 268. The loop formed between the two lengths of theupper strap 104 extending above theupper buckle 102 similarly wrap around and conform to thebar 268 to hold the rigging system snugly in position. Theupper buckle clip 130 firmly biases theupper strap 104 against thegrip wall 125 in thefront slot 152 preventing theupper strap 104 from slipping or loosening. Thespan bumper 144 covering thespan 126 and thesidewall bumpers span bumper 144 provide a high-friction, non-slip surface that further prevents slippage of theupper buckle 102 with respect to thebar 268 and holds the rigging system in a fixed point position. - In a further configuration, the rigging
system 100 may be mounted in a doorjamb not shown) to provide a fixed point mounting location. In this configuration, theupper strap 104 may be pulled tight against thespan 126, thereby removing the loop from the prior configuration that fit around thebar 268. Theupper buckle 102 may then be positioned on one side of a door, both lengths of theupper strap 104 extending from theupper buckle 102 may be placed over the top of the door, and the door may be closed against the door jamb such that the lengths of theupper strap 104 extend through the crack between the door and the door jamb. Theupper buckle 102 may be oriented on the opposite side of the door such that the flat, bottom edge of theupper buckle 102 seats against the door and the door jamb, thus preventing theupper strap 104 from pulling through the crack. Therubber sidewall bumpers system 100 in this manner. - The user to change its length to accommodate for the height of the fixed point, the size of the user, the type of exercise to be performed, or any combination of these needs may easily adjust the rigging
system 100. The primary adjustment to a length of the riggingsystem 100 may be made using thelower buckle 108. By pushing the paddle of thelower buckle clip 170 in thelower buckle 106 to remove the bias holding thelower strap 108 in a fixed position, thelower strap 108 can freely slide within thelower slot 164 around thelower buckle bulkhead 161, thus changing the distance between thelower buckle 108 and thehandle 110. By changing the distance between thelower buckle 108 and thehandle 110, thelower buckle 108 can remain a pre-determined distance from theupper buckle 102 while changing the location of thehandle 110 relative to the fixed-point mount. Thus, thelower buckle 108 can remain at a predetermined distance from the fixed-point mount during adjustment of a vertical position of thehandle 110. However, as described in more detail below, this predetermined distance between theupper buckle 102 andlower buckle 108 can be selectively changed by adjusting the distance between thelower buckle 108 and theupper buckle 102 using the adjustment feature of theupper buckle clip 130. - Once a desired length of the portion of the
lower strap 108 between thelower buckle 106 and thehandle link 116 is achieved to appropriately position the height of thehandle 110, the paddle may be released, allowing thetorsion spring 174 on thelower buckle 106 to bias the grip surface on thelower buckle clip 170 toward thegrip wall 165 and pressing against thelower strap 108 to hold it there between. - Once adjustment of the
lower strap 108 is complete, thelower strap restraint 120 may be used to hold the free end of thelower strap 108 against the length oflower strap 108 under tension in order to avoid possible interference of the free end of thelower strap 108 with the user when performing exercises. Thelower strap restraint 120 may be a length of hook and loop fastener material affixed to the free end of thelower strap 108 that extends laterally to form tab structures. The tabs may be long enough to fold around the width of the opposing length of thelower strap 108 and hook together around the portion of thelower strap 108 under tension. - If in any particular situation, manipulation of the
lower buckle 106 and the length of thelower strap 108 do not adequately achieve the desired length of the riggingsystem 100, the length of theupper strap 104 can likewise be adjusted in combination. Theupper buckle clip 130 can be manipulated to release the bias force on theupper strap 104, allowing the length to be adjusted to a new position, which changes the distance between thelower buckle 104 and theupper buckle 102. Theupper buckle clip 130 can be released after appropriate adjustment of theupper strap 104 to reassert the bias force of theupper buckle clip 130 on theupper strap 104 to hold it firmly in position. - Once adjustment of the
upper strap 104 is complete, theupper strap restraint 118 may be used to hold the free end of theupper strap 104 against the length ofupper strap 104 under tension in order to avoid possible interference of the free end of theupper strap 104 with the user when performing exercises. Theupper strap restraint 118 may be a length of hook and loop fastener material affixed to the free end of theupper strap 104 that extends laterally to form tab structures. The tabs may be long enough to fold around the width of the opposing length of theupper strap 104 and hook together around the portion of theupper strap 108 under tension. - Additionally, by locating the
upper buckle 102 and thelower buckle 106 toward the upper ends of theupper strap 104 andlower strap 108, respectively, the free ends of theupper strap 104 andlower strap 108 are less likely to interfere with the user when performing an exercise. For example, if thelower buckle 106 was located adjacent to the handle straps 114 rather than thehandle link 116, the free end of thelower strap 108 would fall downward toward thehandle 110 andankle strap 112 and possibly interfere with the user when performing exercises. By placing thelower buckle 106 away from a connection point with the handle straps 114, the likelihood of the free end of thelower strap 108 interfering with thehandle 110 or theankle strap 112 is averted or minimized. Positioning thelower buckle 106 away from connection adjacent to the handle straps 114 also prevents the possibility of discomfort of thelower buckle 106 pressing into a user's forearm when performing exercises. -
FIG. 14 depicts an alternate embodiment of a rigging system for suspension exercise training in which thelower strap 108 is provided with a series ofmeasurement markers 240 spaced along the length of thelower strap 108. Themeasurement markers 240 may be positioned at even increments of a particular unit of measure (for example, inches). Themeasurement markers 240 may be marks woven within the web of thelower strap 108, marks screen printed onto the web of thelower strap 108, labels adhered or sewn to the web of thelower strap 108, or formed on thelower strap 108 in any other fashion. As shown inFIG. 14 , the lower buckle may be formed with a recess in thelower buckle bulkhead 161 that creates amarker window 176 to frame or highlight the present selected measurement on thelower strap 108. Such a measurement system may be a significant aid to the user when changing a length of thelower strap 108 to accommodate different exercises during an exercise program. -
FIG. 15 depicts an alternate embodiment of a rigging system for suspension exercise training, wherein twoseparate rigging systems 100 are used in conjunction and connected together by aconnector bar 250. The ankle straps 112 are removed from thehandles 110 on each of the riggingsystems 100. Theconnector bar 250 may then be connected between two opposing ends of thehandles 110; for example, by use of friction fit inserts (not shown) extending from theconnector bar 250 into thehandle cores 190 of each of thehandles 110. Such a configuration may provide a user with an alternate rigging system for the performance of different exercises. Additionally the wider handle surface provided by theconnector bar 250 may provide a simplified or easier platform for users new to suspension exercise training to complete appropriate exercises. - All directional references (e.g., proximal, distal, upper, lower, upward, downward, left, right, lateral, longitudinal, front, back, top, bottom, above, below, vertical, horizontal, radial, axial, clockwise, and counterclockwise) are only used for identification purposes to aid the reader's understanding of the present devices, systems, and structures described herein, and do not create limitations, particularly as to the position, orientation, or use of the invention.
