Description

Technical Field

[0001] This utility model relates to the field of sports equipment, and in particular to a pull-up training device. Background Technology

[0002] Pull-ups, as a typical closed-chain resistance exercise of the upper limbs, are one of the basic training methods for back and upper limb strength. Most of the existing pull-up equipment are simple horizontal bars or power towers. Although they can standardize the grip and posture, they lack effective assistance for beginners in the concentric lifting phase. For those with weak upper limb strength, they often cannot complete the exercise independently because they cannot overcome their own body weight. Existing devices generally lack mechanisms to provide controllable upward assistance, making it difficult to meet the needs of beginner and progressive training. Utility Model Content

[0003] The purpose of this invention is to provide a pull-up trainer that provides stable and graded foot pedal assistance through lateral multi-stage pedals, while the telescopic upright and detachable pedals are adaptable to different heights and stages, effectively improving motion control and meeting the training needs of beginners.

[0004] This utility model is achieved through the following measures: A pull-up trainer includes a base, with adjustable height telescopic columns vertically arranged on the left and right sides of the base, and a gripping crossbar between the tops of the telescopic columns on both sides. The feature is that it also includes a foot pedal assist component disposed on one side of the telescopic columns and on the base. The foot pedal assist component includes support columns disposed on the left and right sides of the base, and a foot pedal frame is disposed between the two support columns.

[0005] The specific features of this utility model also include: The base includes left and right support legs extending in the front-to-back direction and a bottom crossbeam connecting the two support legs. The telescopic column is provided on both support legs.

[0006] The footrest frame includes at least two parallel footrests, which are covered with anti-slip coverings or have anti-slip textures.

[0007] The gripping crossbar is provided with mounting sleeves at both ends, and the mounting sleeves are provided at the corresponding ends of the telescopic column.

[0008] A reinforcing link is provided between the telescopic column and the supporting column on the same side.

[0009] The bottom of the support foot is equipped with an anti-slip component.

[0010] The beneficial effects of this invention are as follows: This device provides stable and graded pedal assistance through lateral multi-stage pedals, while the telescopic column and detachable pedals are adaptable to different heights and stages, effectively improving motion control and meeting the training needs of beginners.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] See Figure 1-4 A pull-up trainer includes a base, with adjustable height telescopic columns 3 vertically arranged on the left and right sides of the base, and a gripping crossbar 4 between the tops of the telescopic columns 3 on both sides. It also includes a foot pedal assist component arranged on one side of the telescopic column 3 and on the base. The foot pedal assist component includes support columns 6 on the left and right sides of the base, and a foot pedal frame is provided between the two support columns 6.

[0018] The base includes left and right support legs 1 extending in the front-to-back direction and a bottom crossbeam 2 connecting the two support legs 1. Telescopic columns 3 are provided on both support legs 1.

[0019] The telescopic column 3, the support column 6, and the base are all detachably connected for easy transportation and storage. Preferably, the telescopic column 3 is a telescopic tube structure with inner and outer sleeves. The inner tube 302 has multiple rows of positioning holes along the height direction, and the outer tube 301 has positioning parts 303 that cooperate with the positioning holes to adjust and lock the column height in stages. At the same time, the top side wall of the outer tube 301 is also provided with an independent threaded hole, in which a fastening bolt 304 is provided. The end of the fastening bolt 304 passes through the threaded hole and abuts against the inner tube 302, further enhancing the stability of the telescopic column 3.

[0020] The footrest frame includes at least two parallel footrests 7, which are covered with anti-slip coverings or have anti-slip textures.

[0021] Preferably, the two ends of the pedal 7 are detachably connected to the two side support columns 6 respectively. The support columns 6 are provided with mounting holes or slots. The pedal 7 is assembled and disassembled by mounting parts (such as pins, elastic buckles or threaded ends). The number and installation height of pedals 7 can be adjusted according to the training stage, and unused pedals 7 can be removed and stored.

[0022] The two ends of the gripping crossbar 4 are provided with mounting sleeves 5, which are set at the ends of the corresponding telescopic columns 3.

[0023] Mounting sleeve 5 can be installed and removed around the top of telescopic column 3 and positioned using pins or bolts.

[0024] A reinforcing link 8 is provided between the telescopic column 3 and the supporting column 6 on the same side.

[0025] The reinforcing link 8 is connected at one end to the support column 6 and at the other end to the corresponding telescopic column 3, thereby integrating the base, support column 6 and telescopic column 3 into one unit, thus reinforcing the support column 6 and ensuring the stability of the pedal 7 during pedaling.

[0026] The bottom of the support foot 1 is equipped with anti-slip components, which can be pads or suction cups.

[0027] When performing pull-up exercises, the height of the grip bar 4 is adjusted and locked by the telescopic column 3 according to the user's height and training goals. During the pull-up, the user grips the grip bar 4 with both hands and begins to pull up, while simultaneously placing one or both feet on the appropriate height of the footrest 7. By stepping down with the feet, some of the weight is distributed, thereby achieving controllable lower limb assistance. As training progresses, the height of the footrest 7 can be changed or the footrest dependence can be reduced to gradually decrease the assistance.

[0028] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
