This new type relates to adjustable resistance sports equipment.

Sports equipment typically employs a weight stack that is actuated by a user pulling the cable.

Figures 1 through 5 depict the vertical starting orientation, but by modifying the rotational orientation of the actuation hinge cover 142 relative to the respective lever cover 148, any fixed or variable starting orientation can be achieved. Furthermore, the starting orientation can be a pre-tensioned position. As shown, the lever arm 124 is fixedly coupled to the actuation hinge cover such that any rotation of the lever arm 124 is transferred to the actuation pivot cover 142 and thus to the resistance lever arm 152 of the resistance system 150. The lever arm 124 can be actuated by a user applying a force to the input of the user engagement member 122. In accordance with the embodiment depicted in FIGS. 1 through 5, the user engagement member 122 is disposed on the end of the lever arm 124 with the user engagement member 122 oriented generally perpendicular to the lever arm 124.

In accordance with an embodiment, a plurality of abutment bushings 160 are formed on the resistance selection housing 158 relative to the selector actuator 156. As shown, the abutment bushing 160 engages a flex member 170 that is secured to the resistance motion system 100. According to the embodiment shown in Fig. 6, the flex member 170 is attached to the vertical support 130 at the lower end by the first holder 174, and the flex member 170 is attached to the upper end by the second holder. The 174 is attached to the hub housing 146. In addition, a plurality of optional frame bushings 172 are attached to the vertical supports 130 as shown, which can engage the flex members 170. Further details of the structure and operation of the resistance system 150 are provided below with reference to Figures 7-9.

FIG. 7 depicts an expanded view of the resistance system 150, in accordance with an embodiment. As shown, the resistance lever arm 152 includes a main center post 700 that is coupled to the actuation member 120 along with a resistance lever arm 152 to transfer a force input by the user to the resistance lever from the actuation member. arm. A resistance lever arm 152 rotatably coupled to the hub housing 146 extends from the main center post 700, the main center post defining a plurality of adjustment apertures 154, thereby allowing the resistance lever arm to be an index lever for the purpose of The position of the outer casing 158 is selected to be modified relative to the flex member 170. As shown, the resistance lever arm 152 includes a body having a generally rectangular cross-sectional shape and a rounded edge. Moreover, as shown in FIG. 7, the lever arm 152 defines a plurality of adjustment apertures 154 that are sized to selectively receive the selection pin 705, thereby securing the resistance selection housing 158 relative to the resistance lever arm 152. And the location of the adjacent flex member 170. Although the adjustment aperture 154 is depicted as traversing the front body of the lever arm 152, the adjustment aperture 154 can take any suitable alignment direction. Moreover, although a pin and orifice engagement system is depicted in FIG. 7, any of a variety of alternative adjustment mechanisms can be used to selectively secure the position of the resistance selection housing 158 relative to the resistance lever arm 152, including ratcheting. Systems, pinning systems, gear systems, and the like of the above systems, but are not limited thereto.

Continuing with Figure 7, the resistance lever arm 152 is sized to be slidably received in the resistance selection housing 158. In particular, the resistance selection housing 158 includes a body that defines a lever arm receiving aperture 730 that is sized to slidably receive the resistance lever arm 152. The resistance selection housing 158 further includes a selection pin housing 710 formed on a front surface of the resistance selection housing defining a selection pin aperture 720. As shown, the selection pin aperture 720 is sized to receive a selection pin 705 having an insertion stop 707 formed therein. The pin is selected and the selection pin has a selection actuator attached to the selection pin. According to an embodiment, the selection pin 705 is spring loaded into the selection pin aperture 720 to maintain the selection pin 705 in the engaged position until the retention position is overcome by applying a pulling force on the selection actuator 156. Elastic, to disengage.

In accordance with the embodiment illustrated in Figure 7, the lever arm receiving aperture 730 is further sized to align the direction of the resistive lever arm 152 within the resistance selection housing 158 such that the housing is selected to slide up and down the resistance lever arm 152 with the resistance. The selection pin is aligned with the adjustment aperture 154. Since the resistance selection housing has a different position, the user can pull the selection actuator 156, thereby disengaging the selection pin 705 from the adjustment aperture 154 to allow the resistance selection housing 158 to slide along the resistance lever arm 152 until The selection pin 705 engages the desired orifice, thereby locking the position of the resistance selection housing.

In addition, a plurality of bushing shafts 740 are attached to the back surface of the resistance selection housing 158. As shown, the bushing shafts 740 are each configured to receive and secure the abutment bushings 160 by inserting the bushing shafts 740 into the bearing eyelets 750 defined in each of the seat bushings. According to an embodiment, the bushing shaft 740 is secured to the bearing eye 750 of the seat bushing 160 by any fastening system including an interference fit, an adhesive, a mechanical seal The firmware and the like of the above fastening system are not limited thereto. FIG. 7 also depicts a flex member passage 760 formed on each of the abutment bushings 160. In accordance with an embodiment, the flex member passages 760 formed on each of the abutment bushings 160 are sized to engage and place the flex members 170 in the flex member passages 760. This reduces wear on the flex member 170 during use. The inner surface of the flex member passage 760 can have any kind of surface treatment, including, but not limited to, a smooth or rough surface. According to an embodiment, the flex member Channel 760 can be formed from any type of polymer, metal, or synthetic material including nylon.

FIG. 7 further depicts a fixture 174 that couples flexure member 170 to the resistance motion system 100. The flex member 170 and the retainer 174 form the resistive element of the system. As shown, each fixture 174 includes a body that is coupled to a vertical support 130 or a hub housing 146, respectively. As shown, each of the retainers 174 defines a flexure member receiving bore 770 that is sized to receive the flexure member 170. According to an embodiment, once the flex member passes through the flex member bearing hole 770, a kink can be formed in the end of the flex member to increase the size of the end of the flex member 170 to maintain the flex member at the fixture 174. In the middle position, the flexure member is prevented from passing through the flexure member receiving hole 770. Alternatively, a fastener or other flared member can be attached to the end of the flex member 170 to secure the position of the flex member in the fixture 174. The holder 174 is shown to secure the position of the flex member 170, and any number of fastening systems can be used to secure the flex member, including the struts and eyelets, fasteners, adhesives, molds, and fastening systems described above. Analogs, but are by no means limited to them.

The flex member 170 forming the resistance component of the resistance motion system 100 is shown as having a single cylindrical flex member. The flex member is joined by the abutment bushings and flexed laterally to bend or lengthen the flex member 170, depending on the modulus of elasticity exhibited by the flex member 170 to resist motion, and when the transverse bend is applied The flex member is returned to its original position when the force is removed, as will be described in further detail below. FIG. 7 depicts a single flex member 170 that provides the resistance to the resistance motion system 100. However, any of the flex members 170 having different characteristics can be added to the system to selectively modify the resistance to the user's actions. force. Further, the flex member 170 of FIG. 7 is depicted as a column, but the flex member can be of any geometric shape. According to an embodiment, the flex member 170 can be formed of any material that exhibits flexibility and particularly elastic deformation in response to lateral force, including plastic, elastomer, metal, fiber material, Weaving materials, synthetic materials and the like of the above materials, but are not limited to this. According to an embodiment, the flex member is an elastomer member. The elastomer member may be latex rubber, natural rubber, styrene-butadiene rubber, isoprene rubber, butadiene rubber, ethylene propylene rubber, butane rubber, chloroprene rubber, nitrile rubber, ruthenium Oxygen rubber and combinations of such rubbers, but are not limited to this.

In accordance with the present system, selectively changing the position of the resistance selection housing 158 and the associated abutment bushing 160 relative to the resistance lever arm 152 allows the user to controllably modify the experienced resistance during motion. According to an embodiment, the flex member 170 generally follows Hooke's law of elasticity: F=-kx

That is, the resistance (F) applied by the spring or the elastic member is equal to the elastic constant or coefficient (k) multiplied by the negative value of the displacement (x) of the spring or the elastic member.

As shown in Fig. 8, when the resistance selecting outer casing is fixed to the bottom of the resistance lever arm 152, the biasing force input by the user causes the rotation amount R of the resistance lever arm 152, so that the resistance lever arm 152 is opposed to the vertical support. The piece 130 is rotated by an angle θ. As shown in Fig. 8, the flex member 170 is displaced by a relatively large number in this configuration, and thus the flex member 170 exerts a relatively large resistance to the user.

Conversely, as shown in FIG. 9, when the resistance selecting outer casing is fixed to the uppermost portion of the resistance lever arm, the biasing force input by the user causes the same amount of rotation R of the resistance lever arm 152, so that the resistance Lever arm 152 relative to vertical support 130 is still rotated by an angle θ. However, in this configuration setting, the flex member 170 is displaced by a relatively small amount and thus the flex member 170 exerts a relatively small resistance to the user. The placement of the resistance selection housing 158 relative to the pivot assembly 140 determines the relative displacement (x) of the flex member 170, and thus determines the resistance F. For example, the displacement of the abutment bushing 160 is equal to 2L*π*θ, and L is equal to the distance of the self-resistance selection housing 158 relative to the hub assembly 140, as shown in Figures 8 and 9.

As shown, the adjustment apertures of the resistance lever arm 152 are indexed to selectively position the resistance selection housing 158 from the midpoint of the flex member 170 to the uppermost portion of the flex member. Alternatively, the resistance lever arm 152 can be configured to allow the resistance selection housing 158 to be placed anywhere relative to the flex member 170 in order to maximize the possible displacement, and thus maximize the resistance of the flex member. .

Alternative embodiment

Some modifications may be made to the systems depicted in Figures 1 through 9. For example, Figures 10 and 11 depict a resistance motion system 1000 in accordance with an alternate embodiment. The alternative resistance exercise system 1000 is similar to the embodiment depicted in Figures 1 through 9, in that the system includes a base 110, a vertical support 130, a hinge assembly 140, a support handle 128, and a flex member 170. The flex member 170 is secured to the vertical support and the hub assembly. In addition, another resistance motion system 1000 includes a resistance selection housing 158 having a selection actuator 156 and a plurality of abutment bushings 160. As such, as shown, the alternate embodiment includes an actuation member 1024 coupled to the actuation pivot cover 142 that extends downwardly parallel to the vertical support 130 and that terminates in user engagement. Member 122. however, The actuation member 1024 of this alternative embodiment also has utility as a lever arm, and the actuation member 1024 includes a plurality of adjustment apertures 1054 on the sides, thereby creating a positioning lever arm to assist in selectively biasing the resistance selection housing 158 relative to the deflection The curved member 170 is positioned on the actuation member 1024. According to this embodiment, the force applied to the user engagement member 122 causes rotation of the actuation member 1024 such that the abutment bushing 160 engages and displaces the flex member, thereby inputting resistance to rotation of the actuating member 1024. . Similar to the embodiment depicted in FIGS. 1-9, the resistance and resistance selected by the flex member 170 are selected to be proportional to the displacement of the flexure member and the hub assembly 140.

The foregoing embodiments are depicted as including an actuating member 120 in the form of a drop bar that terminates in a user engagement member 122 that can be used to rotationally actuate resistance The lever arm 152 includes a rod, a handle, a cable, a belt, and the like as the above-described actuating member, but is not limited thereto. For example, another embodiment of the present resistance motion system 100 depicted in FIG. 12 includes a cable 1200 that is rotatably coupled to the resistance system 150. In accordance with an embodiment, a universal coupling device such as a lock is attached to cable 1200 to allow coupling of the desired member. According to this embodiment, any movement that imparts a linear force F on the cable 1200, whether from a handle, belt, rod or another cable connected to the cable 1200, will rotate the resistance lever arm 152, thereby bending The flexing member 170 is bent and introduced with a resisting force against the input biasing force F.

In general, the structure of the present disclosure provides an apparatus having a relatively small area and on the one hand providing the performance of several resistance-type motions. More specifically, the apparatus effectively utilizes the resistance created by a single resilient member and, on the one hand, increases flexibility by modifying the joint position of the actuated portion of the structure. This configuration minimizes the size of the system while increasing security and convenience. That is, in contrast to conventional systems that use stacking of weight plates and other resistance systems that provide resistance to muscle movement, the system does not include a heavy resistance member that is lifted up, the resistance member plus gravity provides resistance to the user. . Rather, the present system uses one or more flex members that are selectively and laterally engaged and that are replaced by actuated lever arms to create muscle sculptures for the user and/or Adjusted resistance. The convenience to the user is enhanced by integrating one or more flex members that are coupled to the motion system. The user no longer needs to add or remove discs or resistance members to modify the resistance experienced.

Moreover, by reducing the number of flex members used to provide resistance to the user, the cost of the device is reduced compared to conventional resistance exercise equipment.

What's more, this resistance sports equipment provides a wide range of resistance in small footprint equipment.
