EMBODIMENT

[0014] Cooperation Figures 1 to 6 As shown, the present application discloses an adjustable handrail for fitness equipment, which is installed on a support 1 of the fitness equipment and comprises a handrail 2 and an adjusting assembly 3. The handrail 2 is slidably installed on the support 1 through the adjusting assembly 3. The support 1 is provided with a guide rail 11. The adjusting assembly 3 comprises a sliding seat 31, a lock set 32, a handle 33 and an upper seat 34. The sliding seat 31 is slidably installed on the guide rail 11. The sliding seat 31 is provided with a lock groove 311, a rotating hole 312 and a lower groove 313 which are in communication with each other and are used for mounting the handrail 2. The lock set 32 is arranged in the lock groove 311. The handle 33 is rotatably installed in the rotating hole 312 through a rotating part 35 and cooperates with the lock set 32. The upper seat 34 is installed on the sliding seat 31 and is provided with an upper groove 341 which is symmetrical to the lower groove 313 and forms a frame hole for mounting the handrail 2. The sliding seat 31 is locked on the guide rail 11 and the handrail 2 is locked in the frame hole through the lock set 32. The handle 33 is rotated to drive the lock set 32 to unlock the sliding seat 31, so as to adjust the position of the handrail 2 and the adjusting assembly 3.

[0015] The lock set 32 comprises an upper pressing piece 321, an upper elastic sheet 322, a lower pressing piece 323, a lower elastic sheet 324 and an adjusting sleeve 325. The sliding base 31 is provided with an upper mounting portion 314 at the top and a lower mounting portion 315 at the bottom. The upper pressing piece 321 is arranged at the upper portion of the lock groove 311 and is connected with the upper elastic sheet 322 and the upper seat 34 by screws respectively. The upper elastic sheet 322 is arranged at the upper mounting portion 314 and is connected by screws. The lower pressing piece 323 is arranged at the lower portion of the lock groove 311 and is connected with the lower elastic sheet 324 by screws. The lower elastic sheet 324 is arranged at the lower mounting portion 315 and is connected by screws. The adjusting sleeve 325 is sleeved on the rotating piece 35 and is arranged between the upper pressing piece 321 and the lower pressing piece 323. The outer wall of the adjusting sleeve 325 is provided with a cam 326. The adjusting sleeve 325 is not concentric with the rotating piece 35 and has a diameter larger than that of the rotating piece 35. When the handle 33 is rotated, the rotating piece 35 and the adjusting sleeve 325 are driven to rotate, and the cam 326 is driven to rotate. The rotating range of the cam 326 is 0-90 degrees. When the cam 326 is at 90 degrees, the adjusting assembly 3 is in an unlocked state. The lower pressing block is flush with the lock groove 311 at the bottom of the sliding base 31 and is not in contact with the guide rail 11. The adjusting assembly 3 is pushed to slide along the guide rail 11 to adjust the position of the adjusting assembly 3 and the handrail frame 2. When the cam 326 is at 0 degrees, the adjusting sleeve 325 pushes the lower pressing block to protrude downwardly out of the lock groove 311 and press the guide rail 11 to limit the movement of the adjusting assembly 3.

[0016] The upper seat 34 and the sliding base 31 are provided with aligned screw holes and are fixed by screws. The tightness of the upper seat 34 and the sliding base 31 is adjusted by adjusting the tightness of the screws, so that the angle of the handrail frame 2 is adjusted. The inner diameter of the frame hole of the upper seat 34 and the sliding base 31 is not limited and is matched with the diameter of the handrail frame. The two are clearance fit to ensure that the handrail frame can rotate flexibly in the frame hole. The abutting surface of the upper seat 34 and the sliding base 31 is provided with four M8 screw holes and is connected by hexagonal screws. When the screws are tightened, the abutting surface of the upper seat and the sliding base generates pressure, extruding the inner wall of the frame hole and fixing the handrail frame by friction force.

[0017] The adjusting sleeve 325 and the rotating piece 35 are provided with aligned screw holes and are fixed by screws. The upper pressing piece 321 and the lower pressing piece 323 are arranged on the upper and lower sides of the adjusting sleeve 325 respectively. The upper pressing piece 321 is clamped by the upper elastic sheet 322 and the lower pressing piece 323 is clamped by the lower elastic sheet 324, so that the adjusting sleeve 325 is limited without external force.

[0018] The adjusting assembly 3 further comprises a top cover 36. The top cover 36 covers the upper seat 34.

[0019] The handrail frame 2 of the embodiment is rotatably installed on the adjusting assembly 3, and the position of the adjusting assembly 3 on the guide rail 11 is locked and unlocked by the handle 33 cooperating with the lock set 32. After being unlocked and loosened, the position of the adjusting assembly 3 on the guide rail can be adjusted, and after being locked, the movement of the adjusting assembly 3 is limited, so that the user can continuously use and quickly adjust.

[0020] The upper pressing piece 321 and the lower pressing piece 323 clamp the outer wall of the adjusting sleeve through the elastic force of the upper elastic sheet 322 and the lower elastic sheet 324. When the handle is not rotated by external force, the adjusting sleeve is limited from rotating by itself due to the clamping force, so that the handle is prevented from being unlocked due to vibration and the like.

[0021] In the unlocked state, the user rotates the handle 33 counterclockwise by 90 degrees, and the adjusting sleeve 325 is synchronously rotated through the rotating piece 35. The cam 326 on the adjusting sleeve is switched to the "minimum radius end downward", and the elastic force of the upper elastic sheet 322 and the lower elastic sheet 324 causes the upper pressing piece 321 and the lower pressing piece 323 to clamp the outer wall of the adjusting sleeve. The lower surface of the lower pressing piece 323 is flush with the bottom of the lock groove 311 of the sliding seat 31, and the lower pressing piece does not contact the guide rail 11, so that the sliding seat can freely slide along the guide rail.

[0022] In the locked state, the user rotates the handle 33 clockwise, i.e., rotates back to 0 degrees, and the cam 326 is switched to the "maximum radius end downward", and the cam surface presses the upper surface of the lower pressing piece 323. The lower pressing piece is moved downward by the pushing force of the cam, breaks through the elastic force of the lower elastic sheet 324, and protrudes the lower surface of the sliding seat lock groove 311 and presses the guide rail 11. The adjusting assembly 3 is completely locked and cannot slide along the guide rail.

[0023] The upper pressing piece 321 is connected to the upper elastic sheet 322 through a screw, and is connected to the screw hole at the bottom of the upper seat 34 through a screw, so as to realize the linkage and fixation of the "upper pressing piece-upper elastic sheet-upper seat". The lower pressing piece 323 is connected to the lower elastic sheet 324 through a screw, and the lower elastic sheet is fixed to the lower mounting portion 315 through a screw, so as to form the fixation of the "lower pressing piece-lower elastic sheet-sliding seat".

[0024] The bottom of the sliding seat 31 of the embodiment is provided with a groove matched with the T-shaped guide rail, and the sliding seat slides along the length direction of the guide rail.

[0025] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical range disclosed by the present application can be easily thought by those skilled in the art, and should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
