Description

Technical Field

[0001] This invention belongs to the field of fitness equipment technology, specifically relating to a multi-unit integrated fitness device that is installed on walls and columns, can be adjusted in multiple heights, can be rotated and folded for storage, and can be assembled in a modular manner. It is suitable for use in homes, balconies, corridors, and other fragmented urban "golden corners and silver edges" scenarios. Background Technology

[0002] With the implementation of the national fitness strategy, utilizing scattered and idle urban spaces to install fitness equipment has become the mainstream direction of industry development. At present, most outdoor public fitness equipment adopts an independent floor-standing column structure. A single column can only be equipped with a single fitness function unit. If two or more upper limb exercise functions are to be integrated, multiple independent columns need to be erected, resulting in a large consumption of steel materials and high construction and installation costs.

[0003] Conventional wall-mounted fitness equipment generally suffers from defects such as fixed and unadjustable height, non-lockable swing angle, and lack of folding and storage structure. Equipment installed outdoors is also susceptible to seasonal shutdowns due to rain, snow, and frost. Rotary wheel fitness equipment has fixed arm length and non-adjustable grip width, resulting in a single exercise mode. Traditional pendulum equipment has a single swing trajectory, making it impossible to switch between multiple exercise postures and difficult to adapt to the personalized usage needs of different groups such as elderly rehabilitation exercises, youth strength training, and adult body shaping and fitness.

[0004] Currently, there is a lack of integrated fitness devices on the market that share a single support column, allow multiple fitness units to be independently raised and lowered, can be rotated and folded for storage, can switch between multiple exercise modes, and are easy to assemble and disassemble. Summary of the Invention

[0005] (a) Purpose of the invention

[0053] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0054] Example 1: Basic Double-Unit Column-Attached Installation Structure

[0055] like Figure 1 Figure 2 As shown, in this embodiment, an independent vertical column (1) is selected as the installation base. The vertical column (1) is locked and fixed to the wall surface by the fixing parts (1.1) at both ends. The column body is provided with a number of pin positioning holes (1.2) at equal intervals along the vertical direction.

[0056] The first adjustment component (2), the second adjustment component (8), and the safety protection component (9) are sequentially installed on the outside of the vertical column from top to bottom. All three components are fitted onto the outside of the vertical column (1) by means of sliding sleeves. The first adjustment component (2) includes a first sliding sleeve (2.1) and a first positioning pin (2.2). The first sliding sleeve (2.1) has a sleeve pin hole (2.4) on its side wall. During daily adjustment, the first positioning pin (2.2) is pulled out, and the first sliding sleeve (2.1) can slide vertically along the column to adjust the height, or rotate around the column axis. After rotating the sleeve 90°, the swing arm fitness unit is close to the column and the wall, and the unit is stored. The first positioning pin (2.2) is then inserted again to lock the sleeve height and circumferential position simultaneously.

[0057] The outer wall of the first sliding sleeve (2.1) is hinged to the swing arm linkage fitness unit (2A) via the first connecting shaft (2.3).

[0058] Combination Figure 4 Figure 5 As shown, the swing arm linkage fitness unit (2A) is composed of a first swing arm assembly and a second swing arm assembly hinged together. The first swing arm (3) is sleeved with the first swing arm telescopic tube (4) to form a telescopic sleeve structure, and the second swing arm (5) is sleeved with the second swing arm telescopic rod (6) to form another set of telescopic sleeves; spring positioning pin holes (3.3, 5.3) are opened on the side walls of both sets of sleeves, and spring pins are used to form a rod length locking assembly. Pulling out the spring pin can freely extend and retract the length of the swing arm, and inserting the spring pin can fix the arm length, thereby changing the swing amplitude.

[0059] The first pendulum (3) is fitted with a first pendulum limit bolt (3.4) at its end, and the two sets of pendulums are hinged together by the pendulum shaft (5.4).

[0060] This unit has three operating conditions:

[0061] Condition 1: The limit bolts are loosened, and the two swing rods move freely together, swinging back and forth synchronously to the left and right.

[0062] Condition 2: The limit bolt abuts and locks the first swing arm (3) in a horizontal position, while only the second swing arm (5) swings up and down;

[0063] Condition 3: The limit bolt is locked and the first swing arm (3) is in a vertical position, while the second swing arm (5) is raised and lowered for training.

[0064] A plastic handle (6.1) is installed at the end of the second swing arm telescopic rod (6) to improve grip comfort. The first swing arm pipe thread cap (3.2) and the second swing arm pipe thread cap (5.2) are used to limit the movement and prevent it from falling off, and the locking nut (5.1) is used to tighten the hinge position.

The plate body has a central rotating shaft hole (8.41) and a ring of stop pin holes (8.42).

[0067] A U-shaped hinge plate (10.1) is welded to the root of the rocker arm (10). The U-shaped hinge plate (10.1) is hinged by passing through the central rotating shaft hole through the fixed pin (8.43). The detachable angle pin (8.44) is inserted into the pin hole (8.42) of different gears to fix the rocker arm (10) at different pitch angles, which can be adapted to different training modes of high and low positions.

[0068] The rocker arm (10) is equipped with a handle shaft guard (10.2) at its outer end, and a telescopic handle assembly (11) is mounted on its outer side. The telescopic handle assembly (11) consists of an outer tube (11.5) and a telescopic inner rod (11.6). The telescopic length is locked by a self-locking spring ball (11.7) and a spring pin hole (11.3). The handle shaft (11.1) is axially fixed with a locking nut (11.2). The anti-slip handle (11.9) is fixed at the end of the right handle (11.4). The eye bolt (11.8) can be connected to external tension accessories.

[0069] Combination Figures 9-12 A reversing locking unit (12) is provided at the root of the telescopic rocker assembly. The reversing locking unit consists of a plunger spring positioning pin (12.1) and a rotating connecting sleeve (12.2).

[0070] Press down the plunger spring locating pin (12.1) and rotate the rotating connecting sleeve (12.2) to switch the locking positions: Locking position one ( Figure 9 The crank handle rotates in the opposite direction, simulating a rowing and lifting motion; Position two ( Figure 10 The crank rotates in the same direction, simulating the flat-push training of the rotating wheel. The two modes are easy to switch between, and the structure is stable and durable.

[0071] Example 3 Safety Protection Components
