detailed description

Referring to Figs. 1-5, the multifunctional fitness chair provided by the present invention comprises a chair-back support frame 10 capable of being supported on the ground, a seat 50 whose rear end is connected to the chair-back support frame, and two left and right Arm flexion and extension training mechanism, the arm flexion and extension training mechanism is mainly composed of an arm flexion and extension load 34, an upper stay rope 30 and an upper stay rope human body support 31, and the upper drawstring human body support is located on the chair-back support frame In the front of the back of the chair, the top of the chair-back support frame is provided with an upper stay rope support and guide mechanism 32, and the upper stay rope support and guide mechanism includes a first fixed pulley 33 for the upper stay rope matched with the upper stay rope , also includes an upper stay rope fixing device capable of fixing the upper stay rope, the upper stay rope straddles the first fixed pulley of the upper stay rope, the front end of which is located in front of the chair-back support frame and The human body supporting part is connected with the upper drawstring, and its rear end is located at the back of the chair-back support frame and connected with the flexion and extension load of the arm. Using this multi-functional fitness chair can carry out a variety of fitness training, for example, use the chair seat as an auxiliary device for squat training, use the left and right arms to perform flexion and extension training for both upper limbs, and fix it with the upper pull rope The device fixes the upper pull rope, and the upper pull rope human body support is used for various suspension training, the ring training is performed with the grip ring and the upper pull rope, and the suspension lift is performed with the chair back support frame or the chair back support frame and the grip ring. Leg training, use the chair seat to perform leg lifts and various abdominal training, use the back panel on the chair back support frame to perform back wall training, etc.

Since the stay rope will go through two 90-degree turns from the vertical state behind the chair-back support frame to the vertical state in front of the chair-back support frame or multiple turns and/or continuous turns with respect to the two 90-degree turns. Turning, in order to realize the first 90-degree turning of the upper stay rope from the vertical state behind the chair back support frame to the horizontal state above the chair back support frame, preferably, the first fixed pulley of the upper stay rope is located at The rear side of the top of the chair-back support frame, in order to realize the second 90-degree turn of the pull cord from the horizontal state above the chair-back support frame to the vertical state in front of the chair-back support frame, preferably, in the The front side of the top of the chair-back support frame is provided with the second fixed pulley of the upper stay rope matched with the upper stay rope, or a curved slide plate is set at the position corresponding to the top of the chair-back support frame and the upper stay rope, so that the upper stay The pull cord is able to make the required 90-degree turn along the chute on the curved skateboard.

Any suitable prior art can be selected for the upper stay rope fixing device. For example, two movable splints opposite to each other are set on the chair back support frame, and the two movable splints are respectively located on both sides of the upper stay rope, and there is a gap allowing the upper stay rope to pass freely between the two splints. When using the splint pushing mechanism to push the two splints to move together or push one splint to press the other splint to move until the upper drawstring between the two splints is clamped and fixed, then fix the two splints or the splint pushing mechanism; Optionally, three horizontally extending push rods located at different heights are set on the chair back support frame. The vertical distance between the rods should be slightly greater than (not less than) the diameter of the middle push rod plus twice the diameter of the upper pull rope. The synchronous push mechanism that can push the two to move synchronously and reversely in the vertical direction. When the upper pull rope needs to be fixed, the middle push rod is first moved horizontally to the other side of the upper and lower push rods through the corresponding push mechanism (while driving the corresponding parts The upper pull rope moves), and then through the corresponding push mechanism to drive the upper and lower push rods to move towards each other (while driving the corresponding parts of the upper pull rope to move), the final position of the three push rods should be exactly the upper one between the push rods The stay rope is clamped, and at the same time, the gap between the upper and lower push rods is smaller than the diameter of the middle push rod, thereby realizing the fixing of the upper stay rope, and the fixing strength is particularly high; The clamp or buckle that holds it in place acts as an upper drawcord anchorage.

Preferably, the chair-back support frame can adopt a frame structure, and is provided with four frames up, down, left, and right, and the frame is equipped with a chair back board used as a chair back, or installed with other structural parts that can be used as a chair back, Such a chair-back support has a simple structure and relatively light weight.

Preferably, the flexion and extension load of the arm adopts weights and/or springs for stretching.

Preferably, the stay cord with adjustable length is used to adapt to different training needs. The stay cord with adjustable length can be selected from any suitable prior art. For example, the stay cord is composed of several stay cord sections The end of each stay rope section is provided with a stay rope connector that can be connected to each other. When using it, it is necessary to select an appropriate number of stay rope sections to be connected to each other to form a stay rope of a suitable length. The stay rope connector can be used Any suitable existing technology (such as various connecting fasteners or connecting buckle assemblies adapted to ropes/belts); for another example, a horizontal pullcord reel that can be wound with a pullcord is provided on the chair back support frame, The upper stay cord is wound on the stay cord reel for a certain number of turns, and the actual extension length of the upper stay cord can be changed by changing the number of turns of the upper stay cord wound on the reel.

Preferably, the chair-back support frame adopts a height-adjustable structure to meet different training needs, and the chair-back support frame with a height-adjustable structure can adopt any suitable existing technology. For example, the chair-back support frame adopts a frame structure with four upper, lower, left, and right frames. The left and right frames are composed of two sections that are inserted into each other. After being fixed, the height adjustment of the chair-back support frame is realized.

Preferably, the connection mode between the rear end of the seat and the back support frame is that the rear end of the seat seat is fixed or movably connected to the back support frame, when the rear end of the seat is movably connected When on the chair-back support frame, the movable connection is a movable connection that allows the seat to rotate around the axis in the left-right direction (number 59 in FIG. 1 shows several different positions during the rotation of the seat).
