[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the embodiments, by Figs. 1-3 The present invention discloses an auxiliary device for a standing device, comprising a backrest frame 1, a sliding frame 2 extending to the outside of the backrest frame 1, a slot 3 on the top of the sliding frame 2, a magnetic suction piece 4 fixedly disposed inside the slot 3, a rotating frame 5 extending to the outside of the slot 3, a support hook 6 fixedly installed on the outside of the rotating frame 5, a limiting component 7 for restricting the rotating frame 5 fixedly installed on the outside of the sliding frame 2, and a height adjusting component 8 that engages with the backrest frame 1 fixedly installed on the outside of the sliding frame 2.
[0023] The rotating frame 5 has a semi-circular groove on its outside, and the limiting component 7 limits the rotating frame 5 through the semi-circular groove.
[0024] The limiting component 7 includes a sliding sleeve 71 fixed to the outside of the sliding frame 2. A spring 72 is fixedly installed on the inner wall of the sliding sleeve 71. The other end of the spring 72 is fixedly connected to a sliding lever 73 that extends into the semi-circular groove to form a locking engagement.
[0025] When the rotating frame 5 rotates to a vertical position, the sliding lever 73 of the limiting component 7 is inserted into the semi-circular groove, and the arc edge of the semi-circular groove forms a surface contact with the lever 73.
[0026] Specifically, the rotating frame 5 is restricted to rotating only within the range of 0°-90°.
[0027] The sliding lever 73 is composed of a sliding piece and a limiting rod whose end shape and size are adapted to the shape and size of the semi-circular groove. The cross-sectional shape and size of the sliding piece are adapted to the cross-sectional shape and size of the inner wall of the sliding sleeve 71.
[0028] In normal operation, the spring 72 pushes the sliding latch 73 into the semi-circular groove. When the rotating frame 5 needs to be folded, the rotating frame 5 can be directly pushed to rotate, causing the inner wall of the semi-circular groove to push the sliding latch 73 to move, while simultaneously stretching and storing the spring 72, making it convenient to re-engage it later.
[0029] The cross-sectional shape and size of the slot 3 are adapted to the overall cross-sectional shape and size of the rotating frame 5 and the support hook 6. When the support hook 6 rotates into the slot 3, the magnetic piece 4 can be attracted to the rotating frame 5.
[0030] Specifically, the inner wall of the support hook 6 is provided with a soft support pad, which is a rubber pad or an air bladder.
[0031] The backrest frame 1 has a limiting groove on its exterior. There are multiple limiting grooves arranged in an array. The height adjustment component 8 is engaged with the backrest frame 1 through the limiting groove. The height adjustment component 8 includes a sliding sleeve 81 and a plug rod 82. The sliding sleeve 81 has a limiting groove inside. The plug rod 82 is slidably connected inside the sliding sleeve 81 and has a limiting block located in the limiting groove on its exterior. The end of the plug rod 82 extends into the limiting groove.
[0032] Press the plug rod 82 to disengage it from the current limiting groove. After sliding the sliding frame 2 to the new position, release the plug rod 82. The limiting block is guided along the limiting groove, and the plug rod 82 automatically snaps into the corresponding limiting groove.
[0033] Working principle:
[0034] The backrest frame 1 is an accessory for the sit-up device, which is connected to the seat cushion through a controllable rotation to achieve the effect of assisting in standing up;
[0035] Before assisting in getting up, the plug-in rod 82 can be pulled up to disengage it from the backrest frame 1, allowing the sliding frame 2 to slide freely. After sliding until the support hook 6 reaches the appropriate position, the plug-in rod 82 can be released to allow it to re-enter through the limiting groove and complete the position adjustment of the sliding frame 2.
[0036] After the sliding frame 2 is adjusted, the arm can be passed through the support hook 6 to complete the torso support. At this time, the backrest frame 1 can be rotated to complete the standing up. After standing up, the support hook 6 can be pushed directly into the slot 3 and the rotating frame 5 can be attracted by the magnetic piece 4, so that the support hook 6 can be well stored and will not affect human movement.
