FIG. 11 shows end portions of an example elastic cord with spaced apart cross sectional enlargement features positioned for attachment to handles or the front edge of the example abdominal exercise device of FIG. 2. In this example, two end portions of a single cord, or end portions of two different cords may be attached to either receptacles A and B on the exercise device handles; or to receptacles C and D on the edge of the device platform.
In this example, the first end portion is shown positioned to be attached at position "A" to the left handle of the exercise device by inserting one of the first end portion's tapered stops 513, 514, or 515 into a left handle cord retention feature. The cord attachment is made by inserting a cord section below the selected tapered stop through the cord retention slot so that the tapered stop is positioned above the tapered receptacle; and then pulling the cord so that the tapered stop nests in the receptacle of the left handle cord retention feature. Since the tapered stop is larger than the tapered receptacle, the tapered stop cannot be pulled through the receptacle. A second cord end portion is shown positioned to be attached at "B" to the right handle of the exercise device by inserting one of the tapered stops 523, 524, or 525 into to the right handle cord retention feature in a similar manner.
In an alternative configuration, selected tapered stops on the first and second end portions of the cord may be attached to the exercise device front edge cord retention features as shown at "C" and "D" respectively. In this example, the front edge cord retention features are show as parallel to the front edge. In other examples, the cord retention features are provided orthogonal, or at other angles relative to the front edge.
In this example, the cross sectional enlargement features are formed by tapered stops created by inserting a tapered plug in a hollow cord, and then securing a tapered cover over the plug portion. FIG. 12A is a side perspective detailed view of an example tapered stop 523. In this example, the tapered stop has a tapered cover 550 with an engraved indicia 563. An upper lip 567 on the cover 550 prevents the cover from slipping down the cord. A pair of slots 568 are provided on the lip to permit the cover to be positioned over the plug. In this example, the lip is a reduced diameter circumferential slotted lip. FIG. 12B is a side perspective detailed view of the tapered stop 550 of FIG. 12A showing a hidden line view of a plug 540 with a larger upper portion 542 than lower portion 544.
In this example, three tapered stops are shown as being formed integral to each end of a single elastic cord. In other examples, two cords or bands may be used rather than a single band or cord. In other examples, other numbers of tapered stops may be provided on one or both ends of a cord.
In other examples, more than two cross sectional enlargement features may be provided on one or both ends of a cord or band, and those features can be formed integral to the elastic band or cord, or provided in another manner such as by tying knots in the band or cord, attaching end elements to an elastic band or cord where the end elements provide enlargement features, or by clamping or adhering beads or other elements to the band or cord at desired locations.
Example- Kit with abdominal exercise device, adjustable resistance cord, and removable handles FIG. 13A is a side perspective view of an example handle 601 with a cord retention housing 610 configured to accept a portion of an adjustable resistance elastic cord. FIG. 13B is a top view of the handle of FIG. 12A. In this example, the handle 601 has a grip 640 with a central strap channel 644. A strap 630 has a first end 632 and a second end 634 secured to the cord retention housing 610, and a middle portion of the strap 630 is routed through the grip channel 644. In this example, the cord retention housing 610 has a single cord retention element 620 with a cord retention slot 622 and a tapered receptacle 626. The cord retention housing 610 also has an extra cord retention slot 616 so that when a tapered stop, such as 514, 515, or 516 is inserted into the tapered receptacle 626, a portion of the cord located between the selected the tapered stop and the end of the cord, may be wrapped over the cord retention housing 610 and inserted into the extra cord retention slot 616.
FIG. 13C is a detailed front perspective view of a cord retention housing 610 for the handle of FIG. 13 A. In this example, the cord retention housing 610 includes a cord retention slot 622 and tapered receptacle 626. An extra cord retention slot 616 on the rear of the cord retention housing is not visible in this view. The first end 632 of strap 630 has been routed trough strap slot 628a and stitched, glued or otherwise secure to the strap; and the second end 634 of the strap has been routed trough strap slot 628b and secured to the strap. The cord retention housing 610 may be used in other cord retention devices such as a foot retention element or attachment clamp.
In other examples, the cord retention housing 610 may include a pair of cord retention elements 620 so that a single handle may secure tapered stops from two end portions of an elastic cord.
In other examples, the handle may be formed with a rigid material rather than a strap. adjustable resistance elastic cord
FIG. 15A is a side view of an example adjustable resistance elastic cord 501 with a first end portion 511 and a second end portion 521. FIG. 15B is a detailed side view of the first end section 511 of the adjustable resistance elastic cord 501 of FIG. 15 A. A first end of the cord is secured to a first handle 601a by inserting tapered stop 513 into the handle as described below. Other tapered stops 514, 515, and 516 are provided in the first end portion in order to permit the user to adjust the working resistance of the cord 501. In this example, a second end of the cord is secured to a second handle 601b by inserting tapered stop 523 into the handle. Other tapered stops 524, 525, and 526 are
provided in the second end portion in order to permit the user to adjust the working resistance of the cord 501.
FIG. 14 is a detailed side view of the first end of the adjustable resistance elastic cord 501 of FIG. 15A showing a pair of tapered stops 513 and 514 with tapered covers 550a and 550b offset from the tapered plug portions for illustration. In this figure, the presence of the tapered plugs is shown by the expansion of the tubing over the tapered plugs at positions 540a and 540b so that the top portion 542 of the tapered plug has expanded the tubing wall more than the bottom portion 544 of the tapered plug. The tapered covers are secured over the tapered plug portions by moving the tapered covers toward the first end of the cord so that the top portion 552 of the tapered cover fits over the top portion 542 of the tapered plug; and the bottom portion 554 of the tapered cover fits over the tapered bottom portion 544 of the tapered plug.
In this example, the tapered covers have lips 567a and 567b which hold the sleeves over the tapered plug portions so that the sleeves do not slip down the cord. In this example, the tapered covers have indicia to permit a user to readily distinguish between the tapered stops. In this example, the tapered cover lips each have a pair of slots which permit the lips to be pulled over the plug portions of the cord.
Kxample- Single \ ariablc resistance exercise cord w ith four tapered stops on eacli end
In the example of FIGs. 15A, 15B, and 14, a vailable resistance exercise cord has two end portions 511 and 512 with four spaced apart tapered stops on each end portion. Each tapered stop 513, 514, 515, 516, 523, 524, 525, and 526 has a tapered plug and a tapered cover with their narrower tapered portions of the internal plugs and tapered covers oriented toward the middle portion of the cord. This orientation permits tapered receptacles 626 on a handle, bar, abdominal exercise device, or other cord restraint device to secure the tapered stop as the cord is expanded; but to permit the tapered stop to be easily removed from the tapered receptacle when there is no tension on the cord. Insertion of the tapered stop is accomplished by positioning a downstream portion of the cord into the cord retention slot 622 and the tapered receptacle 626, and then pulling the cord until the tapered stop is seated in the tapered receptacle. Removal of the tapered stop is accomplished by relaxing cord tension, and then pushing or pulling the tapered stop until an un-stretched cord portion is positioned in the tapered receptacle 626, and then removing the un-stretched cord portion through the cord retention slot 622. In this example, adjacent tapered stop have the same spacing of about 6 inches (15.2 cm). In other examples, a variable spacing may be used, such as increasing the spacing of the tapered stop closer to an end of a cord.
In other examples, a different number of tapered stops may be placed on the variable resistance exercise cord.
In other examples, a plurality of tapered stops may be provided on first end of an adjustable resistance elastic cord, and a fixed handle may be provided on a second end of the cord.
