[0053] Figures 1 to 8 show an embodiment of an adjustable pressure bar for training provided by this utility model.

[0054] The adjustable pressure bar for training includes a support 1, a pressure bar 2, a reset device 3, and a first adjustment component 4.

[0055] The bracket 1 is used to support the pressure rod 2. The pressure rod 2 is provided with a connecting part 21. The connecting part 21 is hinged to the bracket 1 through a rotating shaft 22. The pressure rod 2 can rotate around the rotating shaft 22 to the open position or the use position. The connecting part 21 is provided with a positioning structure 211.

[0056] The reset device 3 is movably connected between the bracket 1 and the pressure rod 2, and is used to drive the pressure rod 2 to rotate to the open position.

[0057] The first adjustment assembly 4 includes a guide 41 and a pin 42. The guide 41 is disposed on the bracket 1, and the pin 42 is slidably engaged with the guide 41. When the pin 42 is subjected to a pushing or pulling force, it can slide along the guide 41. The pin 42 is used to slide to a position locked with the positioning structure 211 when the pressure rod 2 is rotated to the use position, thereby fixing the pressure rod 2 in the use position.

[0058] Adjustable pressure bars for training can be applied to training equipment. Taking a leg strength trainer with a seat 6 as an example, the pressure bar 2 is close to the seat 6 when in use and away from the seat 6 when in the open position. When the user is training in a seated position on the seat 6, the pressure bar 2 is rotated to the use position and then locked in place by the pin 42. At this time, the pressure bar 2 can press down on the user's thigh, assisting the user in performing leg flexion and extension movements.

[0059] After completing the training, the user pulls the pin 42 to disengage from the positioning structure 211 and releases the lock on the pressure rod 2. At this time, the reset device 3 can drive the pressure rod 2 to automatically rotate from the use position to the open position. The user does not need to push the pressure rod 2 himself. The operation is quick and simple, more labor-saving, more convenient, and provides a better user experience.

[0060] In some embodiments, the reset device 3 includes an air spring 30. The air spring 30 has high stability and non-linear elasticity, allowing the pressure rod 2 to rotate smoothly. One end of the air spring 30 is movably connected to the bracket 1, and the other end is movably connected to the pressure rod 2 and close to the connecting part 21. Specifically, one end of the air spring 30 is movably connected to the bracket 1 via a ball joint 31, and the other end is movably connected to the pressure rod 2 via a ball joint 31.

[0061] In other embodiments, the reset device 3 may also be a helical spring, elastic rope, or other elastic device.

[0062] In one specific embodiment, a mounting base 10 is provided at the top of the bracket 1, and a connecting part 21 is provided at one end of the pressure rod 2. The mounting base 10 and the connecting part 21 are hinged together by a rotating shaft 22. A guide member 41 can be fixedly connected to the mounting base 10. The connecting part 21 is configured as a bushing with a cylindrical structure. The rotating shaft 22 is installed in the connecting part 21, and a bearing 23 can be provided between the rotating shaft 22 and the connecting part 21 to allow relative rotation. The opposite ends of the rotating shaft 22 are respectively connected to the mounting base 10. The opposite ends of the rotating shaft 22 can be fixedly connected to the mounting base 10 by fasteners 24.

[0063] Specifically, as shown in Figure 4, the pressure rod 2 includes a mounting rod 25 and a leg pad 26. The connecting part 21 is provided at one end of the mounting rod 25, and the leg pad 26 is sleeved on the mounting rod 25 and fixedly connected to the mounting rod 25 by fasteners.

[0064] In some embodiments, the pivot 22 is arranged laterally, and the pin 42 is arranged laterally and perpendicular to the pivot 22. The lever 2 is in a lateral position when in use, and can rotate upwards around the pivot 22 from the use position to the open position. The user can unlock the lever 2 by pulling the pin 42 laterally outwards.

[0065] In other embodiments, the guide 41 and pin 42 can be arranged vertically or at an angle, and the rotating shaft 22 can also be arranged vertically or at an angle. The pressure rod 2 rotates around the rotating shaft 22 between the open position and the use position, which can restrict the user's legs when in the use position and move away from the user's legs when in the open position.

[0066] Those skilled in the art can set the rotation direction of the pressure bar 2 according to the structural settings of the training equipment or the space limitations of the site.

[0067] In some embodiments, as shown in FIG5, the first adjusting component 4 further includes a first elastic element 43, which engages between the pin 42 and the guide 41 and drives the pin 42 to slide toward the connecting portion 21. The pin 42 can abut against the arcuate surface of the connecting portion 21 under the driving action of the first elastic element 43. When the user rotates the pressure rod 2 to the operating position, the positioning structure 211 rotates to the position corresponding to the pin 42 and can be locked by the pin 42. The first elastic element 43 includes, but is not limited to, a coil spring, a spring sheet, etc.

[0068] In some embodiments, as shown in Figures 4 and 5, one end of the pin 42 near the connecting portion 21 is a locking end 420, and the other end is provided with a handle 44. The locking end 420 is used to lock the positioning structure 211. When the pressure rod 2 is rotated to the working position, the positioning structure 211 corresponds to the locking end 420 of the pin 42. The handle 44 allows the user to pull the pin 42 to unlock the positioning structure 211.

[0069] The connecting part 21 is a bushing for mounting the rotating shaft 22, and the positioning structure 211 is a pin hole. The locking end 420 of the pin 42 is used to insert into the pin hole. The pin 42 slides along the guide member 41, and can be inserted into the pin hole to lock the connecting part 21, or disengage from the pin hole to unlock the connecting part 21. During the rotation of the pressure rod 2 from the open position to the use position, the locking end 420 of the pin 42 slides along the arc-shaped surface of the connecting part 21.

[0070] When the user rotates the pressure rod 2 to the working position, the pin hole rotates to the position corresponding to the locking end 420, and the pin 42 automatically inserts into the pin hole under the driving action of the first elastic element 43, locking the pressure rod 2. The operation is quick and convenient.

[0071] After completing the training, the user pulls the handle 44 outwards. The handle 44 causes the pin 42 to slide, disengaging the locking end 420 from the pin hole and unlocking the lever 2. After unlocking, the lever 2 automatically rotates from the used position to the open position under the drive of the reset device 3, eliminating the need for the user to manually rotate the lever 2. This simple and convenient operation further enhances the user experience.

[0072] Specifically, as shown in Figures 4 and 5, the guide member 41 includes a sleeve 411 and a nut 412. A pin 42 is slidably fitted within the sleeve 411. The sleeve 411 has openings at both ends, with one end facing the connecting portion 21, allowing the locking end 420 of the pin 42 to extend from that end. The other end of the sleeve 411 is used to install the nut 412, and this end has an internal thread. The outer wall of the nut 412 has a matching external thread. The nut 412 has a through hole in the center, through which the pin 42 and the handle 44 are connected.

[0073] The pin 42 includes a guide portion 421 and an extension 422 forming a stepped shaft. The diameter of the guide portion 421 is larger than the diameter of the extension 422, and a stepped surface is formed between the guide portion 421 and the extension 422. The guide portion 421 slides against the inner wall of the sleeve 411, and the locking end 420 is located at the end of the guide portion 421 away from the extension 422. The end of the extension 422 away from the extension 422 extends out from the nut 412 and is connected to the handle 44.

[0074] The first elastic element 43 is a compression spring and is disposed on the extension 422. One end of the first elastic element 43 abuts against the stepped surface formed between the guide portion 421 and the extension 422, and the other end abuts against the nut 412.

[0075] In some embodiments, as shown in Figures 6 and 7, the bracket 1 includes a support frame 11 and an adjusting frame 12. The support frame 11 is provided with a vertically extending slide rail 111, and the adjusting frame 12 is slidably fitted in the slide rail 111. The rotating shaft 22 is connected to the adjusting frame 12, and the reset device 3 is movably connected between the support frame 11 and the pressure rod 2.

[0076] The support frame 11 is fixed in position, and the adjustment frame 12 is located above the support frame 11. The top of the adjustment frame 12 is connected to the pressure rod 2, and the bottom of the adjustment frame 12 extends into the slide rail 111. The adjustment frame 12 slides along the slide rail 111, which can adjust the height position of the pressure rod 2 to accommodate users of different body types.

[0077] One end of the reset device 3 is movably connected to the support frame 11, and the other end is movably connected to the pressure rod 2, enabling the adjustment frame 12 to be driven by the pressure rod 2. The reset device 3 is used to provide an upward sliding force to the adjustment frame 12 through the pressure rod 2.

[0078] A sliding member 123 can be provided between the adjusting frame 12 and the slide rail 111 to assist the adjusting frame 12 in sliding in the slide rail 111.

[0079] In some embodiments, as shown in Figures 6, 7, and 8, a second adjustment assembly 5 is provided on the bracket 1. The second adjustment assembly 5 includes an adjustment handle 51 and a second elastic member 52. The adjustment handle 51 is hinged to the support frame 11, and the second elastic member 52 is disposed between the adjustment handle 51 and the support frame 11.

[0080] The adjustment handle 51 is provided with a limiting protrusion 511, the slide rail 111 is provided with a clearance through hole 112, and the adjustment frame 12 is provided with multiple limiting holes 121, which are arranged along the extension direction of the slide rail 111.

[0081] The adjusting handle 51 is located on the outside of the support frame 11, and the position of the limiting protrusion 511 corresponds to the position of the clearance through hole 112. When the adjusting frame 12 slides along the slide rail 111, the multiple limiting holes 121 can pass through the clearance through hole 112 in sequence.

[0082] The second elastic element 52 drives the adjusting handle 51 to rotate around the hinge shaft 53 until the limiting protrusion 511 extends into the clearance through hole 112. The limiting protrusion 511 engages with the corresponding limiting hole 121 through the clearance through hole 112, thereby locking the position of the adjusting frame 12. The second elastic element 52 can be a torsion spring, compression spring, spring sheet, or other conventional elastic components.

[0083] The user can rotate the adjustment handle 51 to disengage the limiting protrusion 511 from the limiting hole 121, thereby unlocking the adjustment bracket 12.

[0084] Users can adjust the pressure rod 2 and the adjusting bracket 12 to a suitable height as needed, and then release the adjusting handle 51. Under the driving action of the second elastic element 52, the adjusting handle 51 automatically inserts into the corresponding limiting hole 121 to fix the position of the adjusting bracket 12.

[0085] After the adjustment handle 51 unlocks the adjustment frame 12, the user can adjust the height of the pressure rod 2 and the adjustment frame 12 more easily because the reset device 3 provides an upward sliding force to the adjustment frame 12.

[0086] In one specific embodiment, as shown in FIG8, the adjusting handle 51 can be configured as a pressure plate structure, with the hinge shaft 53 connecting the two ends of the adjusting handle 51. One end of the adjusting handle 51 is the operating end 512, and the limiting protrusion 511 is provided at the other end of the adjusting handle 51. Under the driving action of the second elastic member 52, the operating end 512 of the adjusting handle 51 tilts up, and the user can press the operating end 512 to disengage the limiting protrusion 511 from the limiting hole 121.

[0087] Furthermore, as shown in Figure 8, the limiting protrusion 511 is provided with a guide slope 5111, which slopes downward along the direction from the clearance through hole 112 to the limiting hole 121. The guide slope 5111 is used to cooperate with the limiting hole 121.

[0088] With the limiting protrusion 511 locking the adjusting frame 12, a downward pressure is applied to the adjusting frame 12. The inner wall of the limiting hole 121 exerts force on the limiting protrusion 511 through the guide inclined surface 5111, causing the limiting protrusion 511 to overcome the elastic force of the second elastic member 52 and disengage from the limiting hole 121, thus unlocking the adjusting frame 12. If the downward pressure is continued to be applied to the adjusting frame 12, the adjusting frame 12 can overcome the force of the reset device 3 and slide downward along the slide 111.

[0089] When the height of the pressure rod 2 needs to be adjusted, the user can directly press down the pressure rod 2 or the adjusting bracket 12. After the adjusting bracket 12 descends to the appropriate height, the force is stopped, and the second elastic element 52 can drive the limiting protrusion 511 to automatically insert into the limiting hole 121 corresponding to the position of the clearance through hole 112, locking the position of the adjusting bracket 12. The guide slope 5111 makes the limiting protrusion 511 form a tip, making it easier to insert into the limiting hole 121.

[0090] If the user stops applying downward force to the pressure rod 2 or the adjustment frame 12, the positions of the clearance through hole 112 and the multiple limit holes 121 will not correspond. The reset device 3 can automatically adjust and drive the adjustment frame 12 to slide upward until the position of the next limit hole 121 corresponds to the limit protrusion 511. Under the driving action of the second elastic element 52, the limit protrusion 511 will automatically insert into the limit hole 121, thus avoiding the problem of the limit protrusion 511 getting stuck.

[0091] In some embodiments, as shown in Figures 7 and 8, a limiting structure is provided between the adjusting frame 12 and the slide rail 111. The limiting structure is configured to restrict the adjusting frame 12 from sliding along the slide rail 111 between a first position and a second position, with the first position being lower than the second position. The reset device 3 is used to drive the adjusting frame 12 to slide from the first position to the second position by means of the pressure rod 2.

[0092] The limiting structure includes a limiting member 113 disposed on the slide rail 111 and a limiting rail 122 disposed on the adjusting frame 12. The limiting rail 122 extends in the same direction as the slide rail 111. The limiting member 113 cooperates with the limiting rail 122 and slides within the limiting rail 122.

[0093] The limiting member 113 can be a fastening screw, the limiting track 122 can be an elongated hole, and the support frame 11 is provided with a mounting hole for installing the fastening screw. The end of the fastening screw extends into the elongated hole, limiting the sliding of the adjusting frame 12 between the first position and the second position.

[0094] Taking the adjustable pressure bar for training as an example, its usage is as follows.

[0095] When the adjustable pressure bar 2 is in the open position, it stands upright on the support 1. The user sits on the seat 6 and then presses down on the pressure bar 2, rotating it downwards around the pivot 22 from the open position, closer to the user's legs. During rotation, the pressure bar 2 compresses the air spring 30. When rotated to the use position, the positioning structure 211 on its connecting part 21 corresponds to the pin 42 of the first adjustment component 4. Driven by the first elastic element 43, the pin 42 can automatically insert into the positioning structure 211, thereby automatically locking the pressure bar 2 in the use position.

[0096] The user continues to apply force downwards to the pressure rod 2. The pressure rod 2 causes the adjusting bracket 12 of the support 1 to slide downwards along the slide rail 111 of the support frame 11, continuing to compress the air spring 30. After the pressure rod 2 descends to a suitable height, the force applied to the pressure rod 2 is stopped. Under the driving action of the second elastic element 52, the adjusting handle 51 of the second adjusting component 5 engages with the limiting protrusion 511 through the clearance through hole 112 and the corresponding limiting hole 121, thereby positioning the adjusting bracket 12.

[0097] At this time, the first adjustment component 4 locks the pressure bar 2, and the second adjustment component 5 locks the adjustment frame 12. The user's legs are fixed by the pressure bar 2, and the user can perform leg flexion and extension training with the assistance of the pressure bar 2.

[0098] After completing the training, the user pulls the handle 44 of the first adjustment component 4, causing the pin 42 to disengage from the positioning structure 211, unlocking the pressure lever 2. The air spring 30 then drives the pressure lever 2 to automatically lift, rotating it from the use position to the open position, away from the user's legs, allowing the user to leave the seat. At this time, the height of the adjustment frame 12 remains unchanged, and the same user does not need to adjust the position of the adjustment frame 12 when using the pressure lever 2 again.

[0099] When other users use the lever 2, they can press the adjustment handle 51 of the second adjustment component 5 to unlock the adjustment frame 12. The adjustment frame 12 slides upward under the drive of the air spring 3. Other users sit on the seat 6, rotate the lever 2 from the open position downward to the use position, and then continue to apply downward force to adjust the height of the adjustment frame 12 so that the lever 2 is suitable for the height of the legs.

[0100] This invention also provides a training device, including the aforementioned adjustable pressure bar for training. The adjustable pressure bar can press down on the user's legs, assisting the user in performing leg flexion and extension, sit-ups, or other training movements.
