Description

Fitness apparatus, weight adjustment device, method for adjusting weight on fitness apparatus, and weight adjustment ring

Technical Field

The present invention relates to an exercise apparatus or series of exercise apparatuses which has a simple construction, comprises few elements and allows the actual adjustment of its exercise load while occupying a significantly reduced space with respect to apparatuses used for conventional exercises, since no weight tower or weight plate needs to be used.

The present invention also contemplates a weight adjustment device (or weight adjustment device) suitable for use with exercise apparatus that promotes simplicity and practicality in its use, a reduction in space and cost required to implement the apparatus, and greater precision and flexibility in adjusting the load of the apparatus.

The invention also relates to an exercise apparatus using the above device, a method for weight adjustment of the apparatus and a weight adjustment ring suitable for use with a weight element.

Background

It is known from prior art fitness apparatus to utilize a counterweight tower integrally associated with the apparatus to allow for the addition/adjustment of a counterweight to be functional in the various series of exercises possible with the apparatus. Counterweight towers integral with the equipment typically include a plurality of posts (e.g., metal rods) in which the counterweights are aligned, and adjustment is typically performed by securing a portion of the counterweights in a metal bar (typically by pins) that carries a metal cable and pulley that transfer the load of the counterweights to a portion of the equipment being manipulated by the user.

That is, the manner in which the required weight is adjusted in prior art exercise apparatus requires the user to manually insert or remove the pin into or from the tower until the required weight is reached, which is inconvenient from a practical standpoint in view of the need to manipulate the pin as an additional element and separate from the tower assembly itself. This situation is exacerbated when a user is accompanied by another user to alternately exercise on the same machine and one user uses a different load than the other user, which requires constant manipulation of the tower pins during the rotation.

In addition, it can be observed that the prior art apparatuses occupy a considerable space inside the structure (gymnasium) thanks to the counterweight towers, and their manufacture/realization/maintenance implies high costs thanks to the presence of their towers, whose structure is relatively complex and involves a plurality of elements (cables, individual counterweights, bars, pins, etc.).

Another parallel problem is that if the exercise machine uses weight plates (or weight rings), several support stations for the rings are required at all locations where the machine is used so that the user can either store unused rings or look for rings to supplement the required weight.

Still considering the problems of the prior art related to rings, it is known that the rings known from the prior art also present a number of problems in their application and use, in particular with regard to their insertion in the profile of the fitness apparatus, by inserting them in the longitudinal shaft of the apparatus from one of its longitudinal ends (which implies discomfort and difficulty in its insertion in the profile) or by stacking them in the cross section of the profile (which implies a significant variation in the geometric axis of the profile, with consequent load imbalance, which may cause damages to the apparatus, especially in the case of exercises based on the rotation of the profile with respect to the fixed point of the apparatus).

Furthermore, the prior art discloses some attempts to overcome the above problems, but without absolute success. Document W02006023179 discloses an exercise machine comprising a pivotable profile relative to any point of the machine, which is slidable along the profile to adjust the load felt by the user, allowing the weight to be adjusted by adjusting the moment acting on the profile. However, such machines use a counterweight that is manually inserted and fixed by the user in a sliding base, which considerably hinders the adjustment of the movement load and therefore does not solve the inconveniences of the prior art. Furthermore, such an apparatus from W02006023179 uses cables, pulleys and a large number of bars to allow the transmission of the user's actions in the movement of the counterweight profile, which implies a high complexity of manufacture, maintenance and implementation of the apparatus as a whole.

Another document that may be mentioned is US 2015/014.8200, which discloses an exercise machine comprising resistance elements applied to pivotable profiles of the machine, which are able to slide along the profiles to increase the difficulty of exercise. However, it is observed that the counterweight causing the exercise load of the equipment disclosed in this document is completely arranged in the counterweight tower, i.e. the equipment in the document concerned still needs to work correctly using the counterweight tower and does not propose to eliminate the counterweight tower itself, bringing about the same prior art problems described above.

Detailed Description

Figures 1 to 4 disclose the apparatus of the invention in what is considered to be a preferred embodiment and some of its other possible embodiments. Figures 5 to 12 show the device of the invention in its preferred embodiment. Figures 13 to 15 show the apparatus of the present invention in alternative embodiments thereof and other possible configurations thereof. Fig. 16 to 26 show the device of the present invention in its alternative configuration. Fig. 27-50 show several possible embodiments of the apparatus 2 of the present invention for certain types of exercises, paired for comparison with known prior art apparatus for such same type of exercises. Fig. 45 and 46 show the weight adjustment ring in the embodiment considered to be preferred. Fig. 53-66 show illustrative representations of users of the apparatus of the invention in use in a number of possible embodiments of the invention.

First of all, it should be noted that the term "preferred" should not be understood as mandatory or mandatory and merely characterize embodiments of the specific efficacy of the invention.

The present invention envisages an exercise apparatus of simple and practical construction and use, equipped with a reduced number of elements, easily operable by the user through a single movement (including with one hand), and not requiring a counterweight tower or column to adjust your exercise load, the adjustment being performed on the section bar on which the counterweight rests, i.e. on the same section bar that generates the exercise load performed by the user.

That is, the fitness apparatus 2 comprises a profile 100 provided with a coupling section 100A in which the weighted element 1 can slide selectively along a linear portion of the coupling section. The profile 100 may have any shape, wherein at least a part of its longitudinal extension is able to receive a weight element 1, for example a tube having any transverse shape (square, circular, etc.), which may or may not have an angled portion. It should be noted that the apparatus 2 and its components may be constructed of a wide range of materials, and in particular stainless steel and poured concrete, which are suitable even for outdoor applications.

Said coupling segment 100A can be understood as at least a portion of a profile 100 capable of receiving the weighted element 1. In one possible embodiment, the coupling segment embodiment 100A may be a portion of the profile 100 whose outer surface is linear and flat and which allows the weight element 1 to slide along its length. The weight element 1 may be any element capable of exerting a lateral load on the coupling section 100A when resting on the coupling section 100A. For example, the weight element 1 may be a device 1 as further described, or any other device or element capable of exerting a load on the profile 100 as described above.

It should be noted that the support of the weight element 1 on the profile 100 can be done directly or indirectly. For example, the weight element 1 may be supported directly on the surface of the coupling section 100A of the profile 100, or it may be supported on another element (for example a nylon or rubber cover) which in turn supports or covers the profile 100.

For the sake of clarity, the term "linear portion" may be understood as "longitudinally extending portion", "linear segment", or other synonyms. Also for clarification, the term "selectively slide" should be understood as sliding by a deliberate action, command or manipulation of the weight element 1 by a user. For example, the user can move the weight element 1 laterally along the profile 100 with one or both hands. It is also possible to use mechanical and electrical elements to facilitate the sliding.

That is, the coupling segment 100A of the profile 100 can be pivoted directly by the user at any point relative to the exercise machine 2 to perform the exercise. In this sense, the term "directly pivotable" should be understood as being able to pivot due to a direct user action on the profile 100, that is, the user exerts a force directly on the profile 100 without the use of cables, pulleys, bars or the like. Such action may be performed in a variety of ways, such as lateral, radial, rotational movement, and the like. Such action may also involve indirect user commands, whether electrical or mechanical in nature (e.g., button presses that generate electrical commands or manipulation of a wand that generates movement of a mechanical part), possibly involving a mechanism or not included in the weight element 1.

It should also be noted that the profile 100 can be hinged to impart an angular movement with respect to any point of association between itself and the apparatus 2, whether it be a structural point of the apparatus (for example, a beam, a column, etc.) or any other point of its structure. Furthermore, selective sliding of the weight element 1 along the linear portion of the coupling segment 100A in the first or second direction constitutes an increase or decrease, respectively, in the pivoting load of the profile 100. In this way, for example, sliding of the weight element 1 to the point on the coupling section 100A furthest from the pivot point of the profile 100 will result in an increase in the load required for pivoting of the profile 100, and sliding of the weight element 1 to the point closer to the pivot point of the profile 100 reduces the load required for pivoting of the profile 100. This allows the adjustment of the movement load felt by the user by a simple sliding of the single weight element 1 along the profile 100 in one or the other direction, without the need to adjust the weight tower, for example by means of a pin.

In order to facilitate the pivoting of the profile 100 by the user, it is possible to use support means 100B whose purpose is merely to facilitate the access of the user to the profile 100. For example, the support means 100B may be a handle or a support extension extending from the profile 100. It should be noted, however, that the support means 100B transmits the force applied by the user directly to the profile 100 and therefore not through cables, pulleys or grouped bar constructions.

This is because machine 2 in this way allows resting and sliding on it a weighted element 1 to allow adjusting the kinematic load, profile 100 is identical to the profile 100 that the user directly actuates during the execution of his exercise, thus ensuring that machine 2 is absolutely compact and allows both its adjustment and its use to carry out the exercise, without using counterweight towers, pulleys, cables, trusses, etc. That is, the stack of metal weights arranged in the tower is replaced by a single element that utilizes the distance between its position and the pivotable axis for load adjustment, advantageously reducing the cost and complexity of the equipment, among other advantages.

It is important to note that the apparatus 2 of the present invention has a significantly reduced size compared to currently known exercise apparatus. The elimination of the need for a counterweight tower and a counterweight ring allows a considerable reduction in the space occupied by the apparatus 2 of the invention, observed in a reduction of between 10% and 40%, and in particular between 20% and 30%, and more particularly between 25% and 35%. For example, a reduction of approximately 35% has been observed for exercise devices commonly referred to as "cross-Pull machines" (Yaw Pull). For the exercise machine, commonly referred to as a "shoulder press," a reduction of approximately 28% is observed.

To illustrate the size reduction allowed by the machine 2 presented herein, figures 27-50 disclose several possible embodiments of the machine 2 of the present invention for certain types of exercises, paired with known space technology machines for such same type of exercises, for comparison. Figures 27 to 50 show the overall dimensions of length a, width B and height C of each possible illustrated embodiment of the device 2 of the invention, as defined more fully (in centimeters) for each figure in the following table, compared with the same overall dimensions of length a ', width B ' and height C ' taken from a device of the prior art:

apparatus	A	A'	B	B’	C	C’
							Biceps curl machine (fig. 27-30)	1378	1509	918	1346	1691	1707
Hip lifting machine (fig. 31 to 34)	1413	1510	1045	1329	1344	1709
							Leg lifting machine (fig. 35-38)	1925	2337	1101	1398	1392	2157
Pull-down machine (fig. 39 to 42)	1863	1693	954	1591	1849	1887
							Shoulder lifter (fig. 43-46)	1659	2096	1371	1529	1165	1710
Lying pushing machine (fig. 47 to 50)	1845	2134	1240	1529	764	1710

It is observed that the embodiment of the apparatus 2 of the present invention is always smaller in one or more dimensions than the previous apparatus, which demonstrates the weight reduction it guarantees.

Optionally, the apparatus 2 may further comprise at least one counterweight 100D, which counterweight 100D is arranged on the profile 100 to assist the movement of said profile 100 during the exercise. Counterweight 100D may be an integral part (single piece) of profile 100, or an element associated with profile 100 in any suitable manner, such as by snapping. The counterweight 100D can be arranged at any point of the profile 100 suitable for compensating the weight of the weight element 1 and facilitating the movement of the profile 100 by the user. For example, the counterweight 100D may be arranged at a longitudinal end of the profile 100, which is opposite to the longitudinal portion of the profile 100 in which the device 1 is intended. An example of the use of the counterweight 100D in the apparatus 2 can be seen in fig. 1 and 3.

The invention also envisages an exercise apparatus 2 comprising a profile 100 on which a weight element 1 is supported, the weight element 1 being selectively attachable to the profile 100 when a user performs an action of moving at least a part of the weight element 1.

The user action to move a portion of the weight element 1 may be any action that allows moving a portion, part or element of the weight element 1, such as lateral, radial, rotational movement, etc. Such action may also involve indirect user commands, whether electrical or mechanical, with or without mechanisms that may be incorporated in the weight element 1. The movement of at least a part of the weight element 1 is a function of the action performed by the user. For example, the rotating action may produce a rotation of a portion of the weight element 1, which in turn will configure the selective fixing of the weight element 1 on the profile 100.

It is important to note that the user action is performed on a part of the weight element 1, and not on any other component unrelated to the weight element 1. This is because the adjustment of the load of the apparatus 2 by a user action directly on a portion of the weight element 1 allows to be carried out in a compact, simple and practical manner by a simple and quick movement and can even be performed with one hand, without the need for intermediate elements such as weight towers, sets of rods, cables, pulleys or others. To illustrate the use of the apparatus 2 in its various possible embodiments, fig. 53-66 present representative illustrations of the use of the apparatus 2 by a user in several of its possible embodiments in respective first and second stages of an exercise.

In a possible embodiment, the weight element 1 can be selectively detached from the profile 100 by repeating this action, or by performing this action in the opposite direction to the direction in which the action for fixing the weight element 1 to the profile 100 is performed. For example, the action performed by the user for selectively fastening the weight element 1 on the profile 100 may be a button press. In this case, the action performed for removing the weight element 1 in the profile 100 may be a new button press, i.e. a repetition of the original action. In another example, the action for clamping may be a rotation of a portion of the weight element 1 in a first direction, and the action for unclamping may be a rotation of the same portion in the opposite direction. Other forms of disassembly action may be used, the above being merely possible examples.

Furthermore, the profile 100 (and more particularly the coupling segment 100A) may comprise at least one type of visual marking in its linear portion, to allow the position of the weight element 1 along the profile 100 to be identified. For example, the tag may be a location tag represented numerically by distance units (cm, mm, etc.) or by any other suitable visual representation. Such markings are intended to allow the user to identify the position of the weight element 1 in the profile 100 of the apparatus 2, which is useful for the user to follow the progress of his exercise, or to ensure that if the apparatus 2 has more than one profile 100 (for example, two profiles 100, each manipulated by one arm of the user), the user is able to adjust the position of each weight element 1 appropriately to set the same load on each profile 100.

That is, fig. 1 discloses the apparatus 2 of the present invention in its preferred configuration, associated with a pair of devices 1 of the present invention also in its preferred configuration. The form of apparatus 2 shown in figure 1 is merely an example of an embodiment of exercise apparatus in which the device 1 of the present invention may be applied and the form or function of apparatus 2 need not be that shown. Those skilled in the art will appreciate that the apparatus 1 may be applied to a plurality of different machines dedicated to different types of exercises. It will be further appreciated by those skilled in the art that the device 1 is merely an example of a weight element 1 suitable for use in the apparatus 2 of the present invention, and that the apparatus may be implemented using other types of weight elements 1.

However, the device 1 of the present invention is configured to be selectively slidable along the linear portion of the coupling section 100A of the profile 100 of the apparatus 2, the profile 100 being pivotable with respect to any point of the apparatus 2, the device 1 being configured to be selectively clamped along the linear portion of the coupling section 100A via the clamping element.

That is, the device 1 is configured to selectively attach or detach any longitudinal portion of the profile 100 of the exercise apparatus 2 from any longitudinal portion of the profile 100 of the exercise apparatus 2 by friction between the fastening element of the device 1 and the profile 100. In this sense, the term "longitudinal portion" is understood to mean any portion of at least one surface of the profile 100 that can be contacted by at least one element of the device 1. As an example, the profile 100 of the exercise apparatus 2 may comprise a substantially rectangular geometry (e.g., as seen in fig. 1-4). In this exemplary case, the device 1 may be configured to be attached to or detached from any one of the four lateral surfaces of the rectangular profile 100. In one possible embodiment, the device 1 may be configured to be attached to or detached from a pair of opposite lateral surfaces or even three or four surfaces of the profile 100. Of course, other attachment configurations are possible depending on the desired application, and are not limited to the above examples.

As regards the fastening elements of the device 1, this can be any element suitable for fastening at least the parts of the device 1 to the profile 100. Possible embodiments of the fastening elements are, for example, elements that generate friction between the parts of the device 1 and the profile 100, elements that generate a magnetic field for magnetic attraction between the parts of the device 1 and the profile 100, and any other element that can selectively fix the parts of the device 1 and the profile 100, whether or not they are assisted by other elements such as a combination of holes and pins. Other embodiments of the fastening element will be described later.

In this sense, it is first of all clarified that, advantageously with respect to the prior art, the device 1 of the invention can be fixed at any point of the section bar 100 of the gymnastic apparatus 2, without being restricted with respect to the fixing point. This is mainly due to the fixing or dismounting between the elements of the device 1 relative to the profile 100 by means of fixing elements, which eliminates the need to use pins or holes in the profile 100 to set the weight adjustment. In this way, the user can easily detach the device 1 from the apparatus 2 and move it along the profile 100 to adjust the moment acting in the profile 100 and therefore the load felt during exercise.

It will also be clarified that such adjustment is facilitated by simple operation of the device 1 with the apparatus 2, without the need to add/replace rings or manoeuvring pins/weights, which facilitate and enable user adjustment of the apparatus. In addition, it eliminates the need for a counterweight tower to be used in conjunction with counterweight equipment, which not only reduces the space required to implement the equipment in the gym, but also reduces the cost of the equipment as a whole. However, the use of additional loops may optionally supplement the application of the device 1, as will be explained later.

In a possible embodiment, the attachment or detachment of the device 1 with respect to the profile 100 can be configured by a rotational movement of the device 1 with respect to the profile 100. Moreover, in another possible embodiment, the detachment of the device 1 with respect to the profile 100 allows the longitudinal sliding of the device 1 with respect to the profile 100, and the fixing of the device 1 in the profile 100 interrupts this sliding freedom.

That is, fig. 5 and 6 disclose exploded views of the device 1 of the present invention in its preferred configuration, the device 1 being applied to an apparatus 2 as shown in fig. 1-4. As can be seen, in a possible embodiment, the device 1 comprises a support 10, which support 10 is sheet-like in one possible embodiment and has a substantially circular profile. There is also a bar 20 concentrically and rotatably associated with the support 10 and at least one plate 30 eccentrically and rotatably associated with the support 10. In a possible embodiment, the support 10 comprises a pair of plates 30 associated therewith.

The association between the support 10 and the bar 20 or the pair of plates 30 can be made, for example, by means of axles or fixed pins. In a possible embodiment, a pair of plates 30 is associated with support 10 by means of pins 30' and rod 20 is associated with support 10 by means of a central shaft 20', central shaft 20' being possibly assisted by a concentric pin or any other suitable element for fastening. Preferably, the lever 20 comprises a pair of folds 22, the folds 22 being provided at the longitudinal ends thereof and being configured to engage at least partially with the pair of slots 12 of the support 10. Further, the pair of folded portions 22 can slide within the pair of slots by rotating the lever member 20, and the pair of slots 12 serve as stoppers for the rotation of the lever member 20. Preferably, each plate 30 comprises a cylindrical portion 32 for receiving a pin, a shaft or any other element for fastening to the support 10, and a flat or contact portion 31 associated with this cylindrical portion 32 for other purposes that will be detailed below.

Rod 20 can be selectively rotated. As already stated, the term "selectively" should be understood as "capable of being effected by action, manipulation or command of a user, control system or any other entity", i.e. performing a certain action (in this case, rotation of the lever 20) in a selective, commanded manner. Preferably, the selectivity of the rotation of lever 20 is configured by manipulation of lever 20 by a user in a first or second rotational direction, as will be seen in more detail below.

In addition, the lever 20 is configured to rotate the plate 30 when it is rotated by itself. In a possible configuration, plate 30 or a pair of plates 30 are disposed adjacent to rod 20 such that at least a portion of a pair of plates 30 is pushed by at least a portion of rod 20 as rod 20 rotates. Since the association of the plate 30 is eccentric to the centre of the support 10, the rotational movement constituted by the plate 30 is also eccentric.

The plate 30 is configured to attach itself to the profile 100 of the exercise apparatus 2 or detach itself from the profile 100 by its own rotation. In this sense, in a possible configuration, the fastening element of the device 1 is a plate 30 comprising at least one fastening means 33, the fastening means 33 being configured to fix the plate 30 to the profile 100 of the apparatus 2. Preferably, but not necessarily, a plurality of fastening means 33 is used. Such fastening means 33 are preferably any suitable means capable of fastening to the profile 100. In a first example, the fastening between the plate 30 and the profile 100 is made possible by means of friction between the fastening means 33 and the profile 100. More preferably, the fastening means 33 are made of a material capable of generating high friction on any part of the surface of the profile 100. For example, if the profile 100 is composed of a metallic material or coated with a flexible material such as rubber, the fastening means 33 may be composed of rubber. However, the fastening means 33 may be, for example, a set of elements capable of generating a magnetic field to configure a magnetic attraction between the fastening means 33 and the profile 100. The person skilled in the art will understand that other forms of fastening means 33 may be used for fixing with the profile 100, as long as they allow immobility between the device 1 and the profile 100.

Even more preferably, the fastening means 33 is a combination between a pin and a set of friction elements consisting of a material that generates high friction on the surface of the profile 100, such as rubber. More preferably, the fastening of the fastening means 33 to the profile 100 is performed by a combination of fitting a pin into the hole 101 of the profile 100 (as seen for example in fig. 11 and 12) and friction between the surface of the profile 100 and the friction element. The use of pins is absolutely preferential and can optionally be used to supplement the fixing of the device 1 to the profile 100. It is also important to note that the holes 101 suggested here are not necessarily through holes, as the end use fixation pins are a complementary rather than primary form of fixation. Therefore, the use of apertures (not through) which involve only one of the surfaces of the profile 100 is sufficient to allow the correct fixing of the fastening means 33 to the profile 100.

Still preferably, the profile 100 of the apparatus 2 is of the type comprising a thin longitudinal format, such as an arm or a bar of the support device 1. Those skilled in the art will appreciate that other embodiments of the friction element are possible to achieve the objectives of the present invention and are not limited to the possible configurations described above.

In a possible embodiment, the attachment or detachment of the plate 30 to the profile 100 is done by rotating the plate 30, which in turn is configured by the rotation of the rod 20. In this sense, as best seen in fig. 7 to 10 and in particular in fig. 8, upon rotation by the user in a first direction, the lever 20 pushes a pair of plates 30, which in turn also rotate, but eccentrically to the support 10. This rotation of a pair of plates 30 (or alternatively a single plate 30) detaches the plate 30 from the profile 100. In this preferred configuration, the rotation of the pair of plates 30 raises the pins and the friction means, disconnecting them from the surface 102 and the holes 101 of the profile 100. Also, the use of pins and holes for attaching the device 1 to the profile 100 is absolutely optional.

The disassembly of the plate 30 of the profile 100 allows the device 1 to be displaced along the profile 100, as seen in fig. 9. The fixing of the plate 30 to the profile 100 is performed by rotating the lever 20 (and therefore the plate 30) in a second direction, as shown in fig. 10, which lowers the fastening means and forces it to be reconnected to the profile 100 and locks the device 1. For better understanding, fig. 11 shows the unlocking of the device 1 in a lower view, while fig. 12 shows the device 1 locked on the support 100 in a lower view.

Fig. 13 to 15 disclose alternative configurations and other possible embodiments of the invention, in which the device 1 is associated with an exercise apparatus 2 in which there are two profiles 100 arranged parallel to each other. In this configuration, and according to fig. 16, the device 1 comprises a central body 1A, the central body 1A being provided with a first longitudinal end 1B and a second end 1C opposite the first end 1B. Each of the ends 1B, 1C comprises a support 10 or is associated with a support 10. In this sense, it is to be clarified that each of the sides or ends 1B, 1C of the device 1 will be associated with one of the profiles 100 of the apparatus 2 of this alternative configuration, such as each side of the device 1 in this alternative configuration will have a similar structure to the device 1 of the preferred configuration. More specifically, the device 1 of this preferred configuration comprises a bar 20 associated concentrically and rotatably with each support 10 and at least one plate 30 associated eccentrically and rotatably with each support 10. Furthermore, each lever 20 is selectively rotated according to the user's command, and each lever 20 is configured to rotate its respective plate 30 by its own rotation. In addition, each plate 30 is configured to attach or detach one of the profiles 100 of the apparatus 2 by its own rotation. In this configuration, the apparatus 2 may also comprise at least one spring element 100C connected to the device 1 and to a portion of the profile 100. Preferably, two spring elements 100c are used, one for each profile 100, and each connected to one of the longitudinal ends of the device 1. Such a spring element 100C is configured to allow the device 1 to slide more easily along the profile 100 when moving in an upward direction, thereby facilitating the adjustment of the movement load when moving the device 1 upward.

That is, it is clear that the structure of the device 1 in its alternative configuration is similar to that of the device 1 in its preferred configuration, except that the preferred configuration of the device 1 is "duplicated" for both sides of the central body 1A, to allow it to be associated with two profiles 100 instead of only one profile 100. Fig. 18 to 24 disclose the locking and unlocking procedure of the device 1 on the profile 100 in its alternative configuration, similar to the one used for the preferred configuration, except that the rotation performed by the user for unlocking acts simultaneously on the two levers 20, allowing the unlocking of the two plates 30 of the profile 100.

Some other possible embodiments applicable to the device 1 are described below.

In a possible embodiment, the support 10 is fixedly associated with the plate 40, and the association between the support 10 and the plate 40 configures an interface 50 for receiving the profile 100. As seen in fig. 5 and 16, the device 1 comprises a plate 40, which plate 40 is associated with the support 10 by means of preferably fixed axles 41 and more preferably axles arranged in the upper and lower parts of the plate 40. As seen in fig. 11, 12 and 25, 26, the association between the plate 40 and the support 10 establishes a spacing between these two elements, i.e. the interface 50. The interface 50 is configured to receive or accommodate the profile 100 of the apparatus 2, allowing the device 1 to be supported by the profile 100. Preferably, the support of the device 1 on the profile 100 is achieved by inserting the profile 100 between the upper fixing shaft 41 and the lower fixing shaft 41. In a possible embodiment, the fixed shaft 41 may comprise bearing elements (for example bushings, bearings themselves or any other suitable element) arranged along its length to facilitate the sliding of the device 1 on the profile 100.

In another possible embodiment, lever 20 includes at least one protrusion 21, and protrusion 21 is configured to displace contact portion 31 of plate 30 as lever 20 is rotated. In this sense, the protrusion 21 is preferably arranged on the lever 20 such that the contact portion 31 of the adjacent plate 30 is maintained. The projections 21 may be constituted by bushings projecting from the tabs (tab) of the rod 20 or any other possible configuration that allows the projections 21 to effectively push the contact portions 31 of their corresponding plates 30.

In another possible configuration, the support 10 comprises at least one opening 11, the opening 11 being configured for passing through at least a portion of the contact portion 31 of the plate 30. As best seen in fig. 11, 12 and 25, 26, the contact portions 31 of the plates 30 extend through the openings 11 or through their respective supports 10, such that each plate 30 is associated with its respective support 10 by its outer face and each bar 20 is associated with its respective support 10 by its inner face. This allows the interaction of the contact portion 31 of the plate 30 with the profile 100 of the apparatus 2, while keeping the assembly compact.

In another possible configuration, device 1 comprises a handwheel 60 fixedly associated with lever 20, this handwheel 60 being configured to be selectively rotated by the user and configuring the rotation of lever 20 by its own rotation. In this sense, the association of the handwheel with the lever 20 can be achieved by a shaft and in particular by a central shaft lever 20' such that a rotational movement of the handwheel 60 is transmitted to the lever 20. For an alternative configuration of the invention, the wheel 60 is arranged in the central body 1A so that the rotation of the wheel 60 configures the rotation of both levers 20 simultaneously.

Moreover, in another possible embodiment, the device 1 comprises a spring element 70, which spring element 70 is associated with the support 10 by one of its ends and with the plate 30 by its other opposite end. The spring element 70 is intended to force the plate 30 back to the locked position of the profile 100 after the user unlocks and moves the device 1, thereby eliminating the need for a rotational movement to lock the device 1 in the profile 100.

Preferably, the device 1 also comprises a cover 80 associated with the plate 40 for closing the components of the device 1. The cover 80 also comprises a hollow opening 81 for the passage of the profile 100 of the apparatus 2.

As is apparent from the description provided above, the present invention has a number of advantages over prior art devices and apparatus. First, it is sufficient to eliminate the use of counterweight towers for adjustment, adjusting the position of the device 1 in the profile 100 of the apparatus 2 so that a moment/torque is required for the movement/lifting of the profile 100, thereby changing the load of the movement. Moreover, the adjustment of the device 1 over the length of the profile 100 is carried out in an extremely simple manner, requiring only a user action (in the preferred embodiment, the rotation of the lever 20 in the first direction) to unlock the assembly and allow the sliding and position adjustment of the device 1 on the profile 100. It is important to note that the construction of the apparatus 2 is advantageously simpler and therefore less costly in manufacturing, implementing and maintaining it, since fewer parts are required for its operation (no counterweight tower, loop tower, cables, pulleys, etc.) and its dimensions are significantly reduced compared to the prior art apparatuses. With particular regard to the manufacture of the entire apparatus 2, a saving of 30% to 40% of the total cost is estimated with respect to the conventional apparatuses of the prior art. Furthermore, if necessary, a replacement of the weight element 1 (device 1) is necessary, which can be performed very simply without the need to remove the weight tower, pulleys, cables, bars, etc.

It is also noted that the device 1 and apparatus 2 of the present application are advantageously suitable for outdoor applications, i.e. outdoor fitness facilities. This is because, as already explained, the absence of the use of towers allows for reduced size and greater utility of use, characteristics which are advantageous for outdoor applications. At the same time, the likelihood of damage or theft of loose components such as rings and pins is reduced, as the devices and apparatus of the present invention do not necessarily make use of these components. In this sense, the fact that the apparatus 2 does not have loose parts (rings or cables, pulleys, etc.) allows its correct application in free areas, avoiding damages as well as losing and damaging the structure of the apparatus. Another feature that allows advantageous application in free areas is the fact that the apparatus has many possibilities for adjustment.

Furthermore, it is important to note that, in a possible embodiment, the apparatus 2 of the invention may comprise a locking element, such as a stop or limit switch, provided at any point of the longitudinal extension of its profile 100, which is configured to limit the sliding path of the device 1, in order to prevent the device 1 from being improperly removed from the device 2. The locking element may implement any particular means or tool for its removal to allow maintenance of the device 1 as required.

It is also important to note that the device 1 of the invention is easily adaptable to any existing fitness apparatus, strictly speaking, without requiring special adaptations to the apparatus, as long as it comprises a profile 100 for receiving the device 1, which profile 100 is generally present in many apparatuses known in the art. Furthermore, the device 1 of the invention allows to reduce the size of the existing equipment, since after its implementation, the removal of any additional elements (counterweight towers, bars, pulleys, etc.) is possible.

According to the above-described apparatus and apparatus embodiments, the present invention also provides a method of weight adjustment of an exercise apparatus 2 by a regulator device 1, the method comprising the steps of:

selectively fixing or loosening the weight element 1 of the coupling section 100A of the profile 100 of the exercise apparatus 2 by means of the fastening element of the device 1.

In a possible embodiment, the method further provides the steps of:

-manoeuvring the weight element 1 with respect to the profile 100 of the apparatus for detaching the weight element 1 from the profile 100;

-moving the weight element 1 along the linear portion of the coupling section 100A of the profile 100; and

by means of the fastening element of the weight element 1, the weight element 1 is manoeuvred with respect to the profile (100) of the apparatus to fasten the weight element 1 to the linear portion of the coupling section 100A of the profile 100.

In another possible embodiment, the method further provides the steps of:

rotating at least one lever 20 of the weight-adjusting device 1 in a first direction to detach at least one plate 30 of the device 1 from at least one profile 100 of the apparatus 2 and allow the longitudinal sliding of the device 1 on the linear portion of the coupling section 100A of the profile 100;

-moving the device 1 along the linear portion of the coupling section 100A of the profile 100; and

by means of the fastening elements of device 1, rod 20 is rotated or simply released in the second direction for fastening device 1 in the linear portion of coupling segment 100A of profile 100.

In another possible embodiment, the method further provides the steps of:

turning the lever 20 of the device 1 by means of the steering wheel 60 in a first sense; and

rotating the lever 20 of the device 1 in the second direction by means of the spring element 70.

It is important to note that the rotation of rod 20 in the second direction to fix plate 30 to profile 100 does not necessarily need to be performed by the user. For example, the rotation of the rod 20 in the second direction can be performed by a traction force exerted by the spring element 70 on the rod 20 in the second direction to return the profile 100 to the initial position, as already explained above.

More specifically, and preferably, rotating the lever 20 in a first direction by the action of the user exerts a tension on the spring element 70, which spring element 70 is associated with the support 10 and with the lever 20 itself. The spring element 70 extends and establishes a pulling reaction force on the rod 20, thereby generating a moment in the second rotational direction. This moment is initially compensated by the user while he keeps lever 20 in the unlocked position. When the user reaches the desired point of the device on the profile 100 and releases the lever 20, the spring element 70 exerts its traction on the lever 20, generating a moment in the second direction which returns the support 10 to its original position, thus locking the device 1 on the profile 100 again.

In addition to the device 1 and the apparatus 2 described above, the present invention also contemplates a weight adjuster ring 90 for application to the weight adjuster device 1. The ring comprises a hollow interior portion 93 having a geometry similar to the outer geometry of the device 1, the hollow interior portion 93 being configured to receive at least a portion of the device 1 within its interior.

The term "similar geometry" should be understood as a geometry of the hollow interior portion 93 that allows the device 1 to be accommodated inside the hollow interior portion 93 of the ring 90. It should be noted that it is still clear to the person skilled in the art that the hollow inner portion 93 need not have exactly the same geometry as the outer geometry of the device 1, for example it is sufficient that a part of this geometry is similar to ensure a proper fit between the two elements.

In a possible embodiment, the ring 90 comprises at least a first portion 91 and a second portion 92 associable with each other, the association between the first portion 91 and the second portion 92 constituting a hollow inner portion 93. In this case, the ring 90 is formed of at least two pieces that can be mated together. Optionally, one of the

ring portions

91, 92 may comprise an integrity of the geometry of the hollow interior portion 93 similar to the outer geometry of the device 1, or each portion of the

ring

91, 92 may comprise a portion of the geometry of the hollow interior portion 93.

In another possible embodiment, at least a

portion

91, 92 of additional ring 90 comprises a recess 910 for fitting in profile 100 of exercise apparatus 2. Said recess 910 comprises a geometry similar to at least a part of the geometry of the profile 100, to allow it to be properly engaged in the element. Recess 910 may be formed in only one of

portions

91, 92, or it may be formed by joining smaller recesses included in

portions

91, 92.

In another possible embodiment, the first portion 91 and the second portion 92 are configured to be fitted transversely to the profile 100 of the exercise apparatus 2. In this case, the fitting of the

portions

91, 92 of the ring 90 in the device 1 and in the profile 100 is carried out transversally, so as to facilitate its assembly in the apparatus 2, without the need for longitudinal associations that would require the insertion of the first part, then of the device, and then of the second part of the grommet. In this lateral snap configuration, the snapping of the

portions

91, 92 takes place simultaneously (as seen in fig. 51, 52).

The use of the ring 90 allows to supplement, when necessary, the maximum kinematic load initially allowed by the device 1. It is important to note, however, that the use of the ring 90 with the device 1 and apparatus 2 of the present invention is optional and a possible choice, but not necessary, depending on the needs of a particular application.

In addition, the ring 90 as proposed herein can allow a sufficient balance of the weight and the geometric center of the profile 100, since it does not require transverse or longitudinal stacking in its application. Moreover, its association with the device 1 is performed quickly and conveniently by simultaneous transversal fitting, avoiding discomfort in the event of increased weight, as is typical for conventional rings.

Having described examples of preferred embodiments, it is to be understood that the scope of the invention includes other possible variations, which are limited only by the contents of the appended claims, including the possible equivalents.
