Description

Exercise equipment

Technical Field

The present invention relates to exercise equipment, and more particularly to a barbell bar stop that can quickly and stably lock a barbell disc to both ends of a barbell bar.

Background

Barbells are a popular type of exercise equipment used in weight training, weight lifting training, and fitness. Existing barbells typically include a barbell bar and a plurality of barbell plates selectively attached to both ends of the barbell bar, respectively, to selectively adjust the total weight of the barbell. The barbell further includes two straps removably attached to the ends of the barbell bar to prevent the barbell disc from sliding off the barbell bar. However, existing barbells have some drawbacks.

Each strap includes an annular clamp that is removably clamped to the barbell bar when the disc is slid in. The gripping strength of the strap may diminish over time due to unwanted sliding action of the weight plate along the bar. Once the gripping force of the strap is reduced, the disc cannot be stably positioned along the barbell bar. Furthermore, when the cuff is broken or lost, the barbell cannot be used. It is worth mentioning that the strap can slide along the barbell bar at any position while blocking the outward sliding motion of the barbell plates. In other words, the weight lifter or trainer will experience gripping the strap on the barbell bar to maintain the barbell discs evenly on the barbell bar. However, small differences in the relative positions of the straps on the barbell bar can cause uneven application of force to the weight lifter.

As shown in FIG. 1, an exercise machine of a first embodiment of the present invention is illustrated, wherein the exercise machine includes a barbell bar assembly and a plurality of barbell plates 10. The barbell bar assembly includes a barbell bar 20 and a barbell bar stopper 30, wherein the barbell plates 10 are slidably connected to both ends from both free ends of the barbell bar 20, respectively.

In one embodiment, the barbell bar stop 30 is built into the end of each barbell bar 20 to increase the peripheral dimension of the end of the barbell bar 20 to slide out of the end of the barbell bar 20 when the barbell disc 10 is placed thereon. As the barbell bar stop 30 is actuated to adjust the peripheral dimensions of the barbell bar 20 back to their original dimensions, the barbell discs 10 are allowed to slide in and out of the ends of the barbell bar 20. Thus, the overall weight of the exercise apparatus of the present invention can be selectively adjusted.

According to the preferred embodiment, each of the barbell plates 10 has a central channel 11, wherein the end of the barbell bar 20 is slidably disposed through the central channel 11 of the barbell plate 10 to connect the barbell plate 10 to the end of the barbell bar 20. Accordingly, when the barbell disc 10 is attached to both ends of the barbell bar 20, the exercise device forms a barbell, and the user can control the exercise device with one hand. The barbell disc 10 is loaded into the barbell bar 20 by sliding in from the free end of the barbell bar 20 in a loading direction of the end. The barbell disc 10 exits the barbell bar 20 by exiting the free end of the barbell bar 20 in an unloading direction at the end, which is opposite the loading direction.

The barbell bar stopper 30 is actuated to a pass position to replace the barbell disc 10 from the barbell bar 20 and a stop position to lock the barbell disc 10 to the barbell bar 20. In particular, in the pass position, the barbell bar stop 30 is aligned along the center axis of the barbell bar 20 to allow the barbell disc 10 to be slid in and out of the end of the barbell bar 20 so that the barbell disc 10 can be removed from the barbell bar 20 and a new one of the barbell discs 10 can be attached. In the blocking position, the barbell bar blocker 30 is raised radially from the barbell bar 20 to block the barbell disc 10 from sliding out of the ends of the barbell bar 20, so as to lock the barbell disc 10 to each of the ends of the barbell bar 20. It is worth mentioning that two or more of the barbell plates 10 can be attached to one of the free ends of the barbell bar 20 and locked by the barbell bar stop 30.

As shown in FIGS. 1 and 2, the barbell bar 20 includes two retaining edges 21 that are spaced apart and formed outwardly to define the barbell bar 20 as two outer portions and a middle portion. The outer portion of the barbell bar 20 is the end portion, and the middle portion of the barbell bar 20 is used as a hand grip. In other words, the end of the barbell bar 20 is defined between the stopper edge 21 and the free end. The diameter of each of the limiting edges 21 is greater than the diameter of the central through slot 11 of the barbell plate 10, such that when the barbell plate 10 is slid along the end of the barbell bar 20, the barbell plate 10 is blocked by the corresponding limiting edge 21 to prevent the barbell plate 10 from sliding into the hand grip of the barbell bar 20.

In one embodiment, each end of the barbell bar 20 has a non-circular cross-section defining an outer surface plane 22, and the barbell bar stop 30 is formed on the outer surface plane 22 of the barbell bar 20, wherein the outer surface plane 22 extends from the corresponding limiting edge 21.

The barbell bar stopper 30 includes a plurality of receiving cavities 31 respectively indented at intervals from the outer surface plane 22 of the barbell bar 20, and a plurality of stoppers 32 respectively movably received in the receiving cavities 31. In the pass position, the stoppers 32 are respectively received in the receiving cavities 31 and aligned along the barbell bar 20, thereby allowing the barbell plates 10 to be slid in and out of the end of the barbell bar 20. In the blocking position, the blocking member 32 is raised from the receiving cavity 31 to block the barbell disc 10 from sliding out of the end of the barbell bar 20.

As shown in FIG. 2, the receiving cavities 31 are communicated with each other to form a receiving channel recessed from the outer surface 22 of the barbell bar 20, wherein the blocking members 32 are supported at intervals along the receiving channel.

Each of the blocking members 32 is pivotally connected within the corresponding accommodating cavity 31, wherein each of the blocking members 32 is pivotally moved in and out of the corresponding accommodating cavity 31. Each of the stop members 32 has a stop surface 321 positioned in a manner that conceals the stop surface 321 when the stop member 32 is moved within the cavity 31, the barbell disc 10 being adapted to be slidably attached to the end of the barbell bar 20. When the stop 32 is moved out of the cavity 31 to protrude beyond the stop surface 321, the disc 10 is adapted to be locked to the end of the bar 20.

According to the preferred embodiment, each of the stop members 32 has a guide surface 322 opposite the stop surface 321 to guide the sliding motion of the weight plate 10 along the end of the barbell bar 20. Accordingly, when the blocking member 32 is received in the receiving cavity 31, the guide surface 322 of the blocking member 32 is aligned with the outer surface plane 22 of the barbell bar 20, and the blocking surface 321 of the blocking member 32 is hidden. As the stop 32 is pivotally moved away from the receiving cavity 31, the stop surface 321 of the stop 32 is raised from the outer planar surface 22 of the barbell bar 20 to stop the barbell disc 10 from sliding out of the end of the barbell bar 20.

In one embodiment, each of the blocking members 32 has a triangular shape defining the blocking surface 321 of the blocking member 32 perpendicular to the outer surface plane 22 of the barbell bar 20, and the guiding surface 321 of the blocking member 32 is inclined to the outer surface plane 22 of the barbell bar 20 when the blocking member 32 is raised from the accommodating cavity 31. In other words, the guide surface 321 of the blocking member 32 is inclined downwardly toward the free end of the barbell bar 20.

The blocking member 30 further includes a plurality of elastic members 33 respectively supported by the accommodating cavities 31 to be biased toward the blocking member 32 such that the blocking surfaces 321 pushing the blocking member 32 are protruded from the outer surface 22 of the barbell bar 20. As shown in fig. 2, each of the elastic members 33 is a coil spring having a bottom end connected to the bottom wall of the accommodating chamber 31 and a top end connected to the blocking member 32, wherein a middle portion of the elastic member 33 is connected to a pivot point of the blocking member 32, so that the elastic member 33 is arranged to provide an elastic force to the blocking member 32 to pivotally push the blocking member 32 away from the accommodating chamber 31, so that the blocking member 32 is located at the blocking position.

Accordingly, each of the barriers 32 is driven individually. Two or more of the stops 32 are provided on the outer surface 32 along the end of each barbell bar 20. One of the blocking elements 32 can be driven to move from its blocking position into the passage position, while the other blocking element 32 is held in the blocking position. In other words, the blocking member 32 may be held in different positions. In one embodiment, three such stops 32 are provided at the end of each of the barbell bars 20, with a first such stop 32 being located proximate the free end of the barbell bar 20, a third such stop 32 being located proximate the limiting edge 21 of the barbell bar 20, and a second such stop 32 being located between the first and third such stops 32. When the weight plate 10 is slid into the end of the weight bar 20 in the loading direction, the inner annular wall of the central channel 11 of the weight plate 10 slides on the guide surface 322 of the first stop 32, pivotally urging the first stop 32 from the blocking position to the passing position. Once the barbell plate 10 passes the first blocking member 32, the first blocking member 31 is pivotally moved from the passage position back to the blocking position by the elastic member 32. Thus, the barbell plate 10 is stopped by the stop surface 321 of the first stop 32, and the barbell plate 10 is prevented from slipping out of the end of the barbell bar 20 in the unloading direction. Accordingly, the barbell plate 10 can be slid further past the second and third stops 32 until the barbell plate 10 is stopped by the stop edge 21 of the barbell bar 20. The position of the barbell plate 10 can be selectively adjusted by the stopper 32. More, two or more of the barbell plates 10 may be locked to one of the ends of the barbell bar 20. To remove the barbell disc 10 from the barbell bar 20, the user can press the stopper 32 to pivotally move the stopper 21 in the accommodating cavity 31. Once the stop 32 is received in the receiving cavity 31 to conceal the stop surface 321 of the stop 32, the barbell disc 10 can be slid out from the free end of the barbell bar 20 in the unloading direction.

FIG. 3 illustrates one possible implementation of the barbell bar blocker 30A, wherein the barbell bar blocker 30A includes a plurality of receiving cavities 31A separately indented from the outer surface 22 of the barbell bar 20, and a plurality of blocking members 32A movably received in the receiving cavities 31A, respectively. Each of the blocking members 32A is moved between the passing position and the blocking position. In the pass position, the blocking members 32A are respectively received in the receiving cavities 31A and aligned along the central axis of the barbell bar 20 to allow the barbell disc 10 to be slid in and out of the end of the barbell bar 20. In the blocking position, the blocking member 32A is raised from the receiving cavity 31A to block the barbell disc 10 from sliding out of the end of the barbell bar 20.

In the above-described manner, each of the blocking members 32A is slidably attached to the barbell bar 20. Specifically, the blocking member 32A is extended perpendicular to the exterior spellings 22 of the barbell bar 20. In addition, each of the blocking members 32A has a triangular shape defining a guide surface 322A and a blocking surface 321A. When the blocking member 32A is received in the receiving cavity 31A, the guide surface 322 of the blocking member 32A is aligned with the exterior arrangement 22 of the barbell bar 20 to hide the blocking surface 321A of the blocking member 32A. When the stop 32A slides out of the receiving cavity 31A, the stop surface 321A of the stop 32A is raised from the outer surface plane 22 of the barbell bar 20 to stop the barbell disc 10 from sliding out of the end of the barbell bar 20.

The barbell bar stopper 30A further includes a plurality of elastic members 33A respectively supported in the accommodating cavities 31A to be biased toward the stoppers 32A so that the stopper surfaces 321A pushing the stoppers 32A are protruded from the outer surface 22 of the barbell bar 20. As shown in fig. 3, each of the elastic members 33A is a compression spring having a bottom end connected to the bottom wall of the accommodating chamber 31A and a top end connected to the blocking member 32A to hold the blocking member 32A in the blocking position, so that the elastic member 33A is arranged to provide an elastic force to the blocking member 32A to push the blocking member 32A upward away from the accommodating chamber 31A, so that the blocking member 32A is in the blocking position. Accordingly, each of the blocking members 32A is individually driven to push the blocking member 32A downward from the blocking position to the passing position.

As shown in fig. 4 and 5, a barbell bar assembly of the exercise machine according to the second embodiment is illustrated, which is another possibility of the first embodiment. The barbell bar assembly includes a barbell bar 20B and a barbell bar stop 30B, wherein the barbell discs 10 are slidably attached to both ends of the barbell bar 20B from the free ends.

According to the second embodiment, the barbell bar 20B includes two retaining edges 21B formed at intervals and outwardly to define the barbell bar 20B as two ends and the hand grip. The end of each of the barbell bars 20B has a circular cross-section defining a plurality of outer circular surfaces 22B, and the barbell bar stoppers 30B are formed on the outer circular surfaces 22B of the barbell bars 20B.

The barbell bar stop 30B includes at least two receiving cavities 31B oppositely indented from the outer circular surface 22B of the barbell bar 20B, at least two stops 32B respectively movably received in the receiving cavities 31B to allow sliding movement of the barbell plates 10 in and out of the end of the barbell bar 20B, and a push drive 33B operatively connected to the free end of the barbell bar 20B. As the push driver 33B is pushed and actuated, the stops 32B are respectively radially raised from the pockets 31B in a synchronized manner to stop the barbell plates 10 from sliding out of the ends of the barbell bars 20B.

As shown in FIG. 5, the receiving cavities 31B are located on opposite sides of the barbell bar 20B and are aligned with each other, with the openings of the receiving cavities 31B facing each other. Each of the blocking members 32B is slidably connected to the barbell bar 20B within the corresponding receiving cavity 31B, wherein each of the blocking members 32B is slidably movable into and out of the corresponding receiving cavity 31B. Specifically, the stop 32B extends radially to the outer circular surface 22B of the barbell bar 20B. Preferably, the stop 32B is provided to each end of the barbell bar 20 proximate the free end.

Each of the blocking members 32B has a blocking end 321B as a free end, and is positioned in such a manner that when the blocking member 32B is moved within the receiving cavity 31B to conceal the blocking end 321B, the weight plate 10 is adapted to be slidably attached to the end of the weight bar 20B. When the blocking member 32B is moved out of the receiving cavity 31B to protrude beyond the blocking end 321B, the barbell disc 10 is adapted to be locked to the end of the barbell bar 20B.

The blocking member 30B further includes a plurality of elastic members 33B respectively supported in the accommodating cavities 31B to be biased toward the blocking member 32B so as to push the blocking ends 321B of the blocking member 32B to protrude from the outer circumferential surface 22B of the barbell bar 20B. As shown in fig. 5, each of the elastic members 33B is a compression spring having an inner end connected to the bottom wall of the accommodating chamber 31B and an outer end connected to the blocking member 32B to hold the blocking member 32B in the blocking position, so that the elastic member 33B is arranged to provide an elastic force to the blocking member 32B to push the blocking member 32B upward away from the accommodating chamber 31B, so that the blocking member 32B is located in the blocking position. Accordingly, each of the blocking members 32B is individually driven to push the blocking member 32B downward from the blocking position to the passing position.

The push drive 33B is provided at the free end of the barbell bar 20B to unlock the blocking member 32B in a simultaneous manner such that the blocking member 32B is released from the passage position to the blocking position. To load the barbell disc 10 onto the barbell bar 20B, the user can move the blocking member 32B from the blocking position to the passing position by depressing the push driver 33B into the receiving cavity 31B to conceal the blocking end 321B of the blocking member 32B from the receiving cavity 31B. The barbell disc 10 is slidable along the loading direction from the free end to the end of the barbell bar 20B. Once the disc 10 is loaded by the barbell bar 20B, the push driver 33B is pushed to drive the stop 32B in the pass direction. The stops 32B project radially from the cavities 31B, respectively, in a synchronized manner to stop the barbell plates 10 from sliding out of the ends of the barbell bars 20B.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are given by way of example only and are not limiting of the utility model. The objects of the utility model have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
