Description

Technical Field

[0001] This utility model relates to a pull-up assist device. It belongs to the field of pull-up assist technology. Background Technology

[0002] Pull-up assistive devices are fitness equipment specifically designed to help users complete pull-ups, especially suitable for those who lack the strength to perform a standard pull-up. These devices provide an effective training tool for those who want to increase their upper body strength but struggle to perform pull-ups independently. By using these devices properly, users can gradually improve their strength and coordination, ultimately achieving the goal of performing pull-ups independently.

[0003] Currently, various pull-up assistive devices are available on the market. These devices primarily reduce the difficulty by providing assistance, enabling beginners or those with weaker strength to perform pull-ups. Existing assistive devices typically use multiple weight blocks for counterweighting. Users adjust the number of fixed weight blocks according to their desired weight, then kneel on a platform. The platform is pulled down by ropes, and during the pull-up, the weight blocks help pull the platform up, thus assisting in the pull-up. However, in practice, the weight blocks need to be manually adjusted, which is cumbersome. Furthermore, sometimes users forget to adjust the weight blocks, and kneeling on the platform in this situation can cause them to slip quickly, posing a safety hazard. Utility Model Content

[0006] A pull-up assist device includes a ground support assembly, which includes a main ground support frame and a vertical ground support frame. The vertical ground support frame is rotatably connected to a first crossbar and a second crossbar at its upper and lower ends, respectively. The first crossbar is connected to a pedal that assists the user in performing pull-ups and rotates with the first crossbar via a pedal connecting rod. There are two pedals, a first crossbar, and a second crossbar.

[0007] The grounding main crossbeam is rotatably connected to a gas spring. The piston rod at the upper end of the gas spring is connected to a second U-shaped connecting piece. The inner side of the second U-shaped connecting piece is coaxially connected to a switch wrench that matches the upper contact switch of the gas spring.

[0008] An adjustment plate is installed at the lower end of the second crossbar, and the adjustment plate has multiple adjustment positions.

[0009] The second U-shaped connecting piece is coaxially connected to the outer side of the first U-shaped connecting piece. One end of the first U-shaped connecting piece is connected to an adjusting rod that matches the adjustment gear. The upper end of the first U-shaped connecting piece is provided with an adjusting handle for adjusting the position and distance of the gas spring lever arm. By adjusting the position of the gas spring lever arm, the magnitude of the auxiliary force can be adjusted to meet the needs of different users at different training stages.

[0010] The second U-shaped connecting piece is connected to two limiting support wheels via a fourth rotating shaft, and the inner side of the second crossbar is provided with a slide rail that matches the limiting support wheels.

[0011] A spring is connected between the fourth rotating shaft and the adjusting rod, which is used to adjust the first U-shaped connecting piece and the second U-shaped connecting piece.

[0012] The lower end of the ground-mounted vertical support is rotatably connected to a first horizontal bar via a first pivot, and the upper end of the ground-mounted vertical support is rotatably connected to a second horizontal bar via a second pivot. The opposite ends of the first and second horizontal bars are connected by a vertical bar.

[0013] Multiple reinforcing tubes are provided between the two second crossbars to enhance the connection strength between them.

[0014] One end of the main grounding crossbeam is equipped with a grounding support, which is in the shape of an "eight".

[0015] This utility model has the following advantages and beneficial effects:

[0016] This utility model relates to a pull-up assist device, comprising a ground support component and an assistive device. The assistive device provides support force through a gas spring. Adjustable plates, adjustable gears, and adjustable handles adjust the magnitude of the gas spring's assist force. Changing the lever arm length adjusts the magnitude of the assist force to adapt to the needs of different training stages, offering a wide range of functions. The entire device assists in completing pull-ups, providing additional support force to help users overcome their own body weight and complete pull-up movements more easily. It achieves multi-muscle group training: the pull-up assist device can effectively train the biceps, triceps, wrist muscles, forearm muscles, shoulders, back muscles, core muscles, and hand muscles. Adjustable resistance: some pull-up assist devices allow users to adjust the assist force according to their own body weight to adapt to the needs of different training stages.
