Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, specifically to a treadmill handrail folding device. Background Technology

[0002] Currently, a treadmill is a type of exercise and fitness equipment. Its general structure consists of a running platform housing a motor, a running belt, and shock absorption. A vertical or inclined support column is installed at the front of the running platform, and a handrail frame with an electronic display and handrails is mounted on top of the column. The overall shape is L-shaped, with the running belt at the back and the electronic display at the front. Users can stand on the treadmill and adjust the speed and incline to perform aerobic exercises such as running, walking, or brisk walking, thus engaging in indoor aerobic exercise.

[0003] The folding parts of existing folding treadmills are mostly located at the uprights and base frame, as shown in Chinese patent publications (CN202920889U and CN202569298U). Although this solves the transportation and storage problems to some extent, the handrails need to be removed to save transportation space, which makes transportation and assembly inconvenient and causes parts to loosen after multiple reassemblies. Utility Model Content

[0004] The purpose of this utility model is to provide a folding device for treadmill handrails. Users can make the treadmill more compact when not in use, reducing the space occupied, according to their own needs or space constraints. At the same time, it increases the flexibility and convenience when using the treadmill, effectively solving the problem of excessively long treadmill handrails occupying too much space, and making it easier to move and store the entire treadmill.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A treadmill handrail folding device includes a switch handle, a connecting rod, a movable limit block, a fixed limit seat, and a mounting base. The mounting base is rotatably connected to one side of the bottom of the fixed limit seat. One end of the switch handle and one end of the movable limit block are rotatably connected to the mounting base, with the movable limit block located below the switch handle. Both ends of the connecting rod are movably connected between the switch handle and the movable limit block. The fixed limit seat has a limiting surface on the side facing the movable limit block that eccentrically contacts and engages with the end of the movable limit block. When the treadmill is in use, the fixed limiting seat is locked to the treadmill column and the mounting seat is locked to the treadmill handrail. After operating the switch handle, the movable limiting block is rotated around the pivot point between itself and the mounting seat through the connecting rod. The movable limiting block locks and unlocks the limiting surface between the movable limiting block and the fixed limiting seat through the rotation action.

[0006] Preferably, a retaining member is also connected between the mounting base and the switch handle, the retaining member causing the switch handle to drive the movable limit block to remain in a locked state.

[0007] Preferably, the retaining member is a tension spring, the mounting base has a second rod protruding, the switch handle has a first rod protruding in the middle, the mounting base has a through hole corresponding to the position of the first rod, the first rod slides through the through hole, and the two ends of the tension spring are respectively hooked onto the first rod and the second rod.

[0008] Preferably, a support member is provided on one side of the bottom of the fixed limiting seat corresponding to the rotation path of the mounting seat. When the mounting seat rotates around the pivot point of the fixed limiting seat to the position of the support member, the support member abuts against the mounting seat.

[0009] Preferably, the support member is a column, and the mounting base is provided with an arc surface that matches the outer contour of the support member at the position corresponding to the support member.

[0010] Preferably, the mounting base above the pivot point between the mounting base and the fixed limiting base is provided with a clearance opening, which allows the mounting base to avoid the treadmill column when rotating.

[0011] Preferably, the clearance opening has a U-shaped opening structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model relates to a handrail folding device used between a handrail frame and a column. It includes a fixed limiting seat fixed to the column and a mounting seat fixed to the handrail frame and connected to the fixed limiting seat. The handrail frame can be flipped forward and backward via a pivot point between the mounting seat and the fixed limiting seat. Flipping forward folds the handrail closer to the column, while flipping backward maintains its functional state. To enable locking and unlocking of the handrail frame, a switch handle and a movable limiting block are rotatably mounted on the mounting seat and connected by a connecting rod. The movable limiting block engages with the fixed limiting seat. Operating the switch handle causes the movable limiting block to rotate around its pivot point with the mounting seat via the connecting rod. This rotation locks and unlocks the movable limiting block with the limiting surface of the fixed limiting seat.

[0013] According to the user's needs or space constraints, the folding device of this utility model allows the treadmill handrail frame to be folded forward and close to the column when not in use, making it more compact and reducing space occupation. At the same time, it also increases the flexibility and convenience of folding it backward to maintain the handrail function when in use. It effectively solves the problem of the treadmill handrail frame being too long and taking up too much space, and facilitates the transportation and storage of the entire treadmill.

Detailed Implementation

[0021] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0022] like Figures 1-6 As shown, this embodiment provides a treadmill handrail folding device for installation between the handrail frame 100 and the upright column 200 of the treadmill. Users can use this folding device to allow the handrail frame 100 to be folded forward and close to the upright column 200 when not in use, making it more compact and reducing space occupation. It also increases the flexibility and convenience of folding the handrail frame 100 backward to maintain its handrail function when in use. This effectively solves the problem of the treadmill handrail frame 100 being too long and occupying too much space, facilitating the transportation and storage of the entire treadmill. The handrail function of the handrail frame 100 is as follows: Figure 4 As shown, the folded state of the handrail frame 100 is as follows: Figure 6 As shown.

[0023] The handrail folding device includes a switch handle 30, a connecting rod 40, a movable limiting block 50, a fixed limiting seat 20, and a mounting seat 10. The fixed limiting seat 20 is locked to the treadmill column 200, and the mounting seat 10 is locked to the handrail frame 100 of the treadmill. In this way, no matter what state the handrail frame 100 is in, the fixed limiting seat 20 remains stationary on the column 200, while the mounting seat 10 will rotate back and forth synchronously with the handrail frame 100.

[0024] In this embodiment, both the mounting base 10 and the fixed limiting base 20 can be made of sheet metal. The fixed limiting base 20 can be fixedly installed at the upper opening of the column 200 by welding. The fixed limiting base 20 has an opening at the bottom front side inside the column 200 and an anti-detachment bushing is fitted in the hole. The mounting base 10 also has a rotating hole at the position corresponding to the anti-detachment bushing. The mounting base 10 is rotatably connected to the fixed limiting base 20 through the anti-detachment bushing. Flipping the mounting base 10 backward can drive the handrail frame 100 to return to the handrail function state forward, while flipping the mounting base 10 forward can drive the handrail frame 100 to fold backward and approach the column 200.

[0025] The so-called forward and backward direction refers to the treadmill belt as the backward direction and the electronic dial as the forward direction.

[0026] In order to enable the handrail frame 100 to flip forward at a large angle, in this embodiment, an avoidance opening 11 is provided on the mounting seat 10 above the turning point between the mounting seat 10 and the fixed limiting seat 20. When the mounting seat 10 rotates forward, it avoids the treadmill column 200 through the avoidance opening 11. After flipping forward to the position, the avoidance opening and the column abut against each other to limit and support the handrail frame. The avoidance opening 11 has a U-shaped opening structure.

[0027] To enhance the structural stability of the handrail frame 100 in its handrail function state, a support member 21 is provided on the bottom rear side of the fixed limiting seat 20 corresponding to the rotation path of the mounting seat 10. When the mounting seat 10 rotates around its pivot point with the fixed limiting seat 20 to the position of the support member 21, the support member 21 abuts against the mounting seat 10. The support member 21 is a column, and the mounting seat 10 at the position corresponding to the support member 21 is designed with an arc surface that matches the outer contour of the support member 21.

[0028] In this embodiment, the front end of the switch handle 30 and the front end of the movable limiting block 50 are rotatably connected to the mounting base 10 by pins, and the movable limiting block 50 is below the switch handle 30. The two ends of the connecting rod 40 are movably connected between the middle of the switch handle 30 and the middle of the movable limiting block 50 by pins. The fixed limiting seat 20 has a limiting surface 22 on the side facing the movable limiting block 50 that is eccentrically contacted and engaged with the end of the movable limiting block 50.

[0029] When the rear end of the switch handle 30 is pulled upward around the point between the switch handle 30 and the mounting base 10, the connecting rod 40 will drive the front end of the movable limit block 50 to be pulled upward around the point between the movable limit block 50 and the mounting base 10. As the front end of the movable limit block 50 is pulled upward, it gradually releases the limiting surface 22 of the fixed limit seat 20. In this way, the handrail frame 100 can be flipped forward around the point between the mounting base 10 and the fixed limit seat 20 to a folded state. Conversely, during the downward reset process of the rear end of the switch handle 30, the connecting rod 40 will drive the front end of the movable limit block 50 to push downward around the pivot point between the movable limit block 50 and the mounting base 10. As the front end of the movable limit block 50 pushes downward, due to eccentric contact, the gap will be larger when the front end of the movable limit block 50 just contacts the limiting surface 22 of the fixed limit seat 20, and then become tighter and tighter. This reduces the shaking of the handrail frame 100 and reduces the machining precision, thereby allowing the handrail frame 100 to be flipped backward around the pivot point between the mounting base 10 and the fixed limit seat 20 to the handrail function state.

[0030] To enhance the locking force between the movable limiting block 50 and the fixed limiting seat 20 in the handrail function state, a retaining member 60 is connected between the mounting base 10 and the switch handle 30 to keep the movable limiting block 50 locked. The retaining member 60 is a tension spring. The mounting base 10 has a second rod portion 12 protruding from it, and the switch handle 30 has a first rod portion 31 protruding from its middle. The mounting base 10 has a through-hole 13 corresponding to the position of the first rod portion 31. The first rod portion 31 slides through the through-hole 13, and the two ends of the tension spring are respectively hooked onto the first rod portion 31 and the second rod portion 12. When the rear end of the switch handle 30 is lifted, the restoring force of the tension spring needs to be overcome and the tension spring needs to be stretched. When the lifting force on the rear end of the switch handle 30 is removed, the restoring force of the tension spring is used to make the movable limiting block 50 engage with the limiting surface 22 of the fixed limiting seat 20.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
