[0002] A bath chair is a chair that allows users to sit and take a bath. It is mainly used by older people or frail patients. Most of the earlier bath chairs were fixed after splicing and installation. This type of chair cannot be folded for storage, so it occupies a large space in the bathroom or toilet, which is not conducive to storage. It needs to be installed by yourself when you buy it, which is more troublesome.

[0003] With the development of society, existing bathing chairs have a folding function. The commonly used structure is that the rear leg tube assembly is directly fastened to the backrest tube assembly, and the seat plate and the backrest tube assembly are connected by a plastic connecting rod. This structure is still relatively troublesome when folding and there is still room for improvement. Summary of the Invention

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0024] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0025] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0026] Reference Figure 1-7 A self-folding bathing chair comprises a front foot assembly 1, a rear foot assembly 2, and a seat cushion 3. The upper end of the front foot assembly 1 is bent with a transverse tube 4 toward the rear foot assembly 2. The end of the transverse tube 4 is bent upward to form a backrest bracket 5. The upper end of the rear foot assembly 2 is hinged on the transverse tube 4. The bottom of the seat cushion 3 is equipped with a rotatable first linkage bracket 6 and a second linkage bracket 7. The two ends of the first linkage bracket 6 are installed on the rear foot assembly 2, and the two ends of the second linkage bracket 7 are installed on the front foot assembly 1. The first linkage bracket 6 and the seat cushion 3 are connected. A hinge 8 is installed in between, which is reset and unfolded by an energy storage torsion spring (when this product is unfolded, the two side leaves of the hinge 8 form an angle less than 180°, and when this product is folded, the two side leaves of the hinge 8 are fully unfolded to 180°). Gently lift the front end of the seat cushion, and the hinge is driven to unfold by the energy storage torsion spring, so that the seat cushion passes through the first linkage bracket and rotates upward with the rear foot assembly as the fulcrum. At the same time, the front foot assembly is driven to rotate through the second linkage bracket and move closer to the rear foot assembly, thereby realizing the automatic folding effect of the bath chair, which can save a lot of effort and is easy to operate even for elderly people.

[0027] Two first rotating seats 9 are symmetrically provided at the bottom of the rear end of the seat cushion 3, and the first linkage bracket 6 is rotatably installed in the first rotating seat 9. The first linkage bracket 6 is located between the first rotating seats 9 and is bent to form a mounting position 10. A fixing part 11 is provided at the bottom of the seat cushion 3 corresponding to the mounting position 10, and both sides of the hinge 8 are respectively installed on the mounting position 10 and the fixing part 11.

[0028] A mounting seat 23 is fixed to the mounting position 10 by welding or the like, and one side of the hinge 8 is fixed to the mounting seat 23 by screws.

[0029] Both ends of the first linkage bracket 6 are bent toward the mounting position 10 to form a first connecting end 12, which is mounted on the rear foot assembly 2. The position of the first connecting end 12 is much lower than that of the mounting position 10. Its function is to increase the length of the lever arm when the first connecting end 12 rotates, thereby increasing the torque when it rotates. The lever arm length between the hinge 8 and the fixing portion 11 is relatively short, and the seat cushion 3 can be more easily tilted up with the rear foot assembly 2 as a fulcrum (if the lever arm at the first connecting end 12 is relatively short, the torques applied to the rear foot assembly 2 and the seat cushion 3 are close, and when the rear foot assembly 2 does not move as a fulcrum, the seat cushion 3 will not move either, that is, the seat cushion 3 will not flip upward).

[0030] The second linkage bracket 7 includes a rotating rod 13 and a mounting rod 14. The mounting rod 14 is mounted on the front foot assembly 1. Two second rotating seats 15 are symmetrically provided at the bottom of the middle end of the seat cushion 3. The rotating rod 13 is rotatably mounted in the second rotating seat 15, and one end of the rotating rod 13 is fixed to the transverse tube 4, and the other end is bent toward the mounting rod 14 to form a connecting rod 16. The end of the connecting rod 16 is fixedly connected to the mounting rod 14 (for example, by welding).

[0031] The function of the mounting rod 14 and the connecting rod 16 is also to increase the length of the lever arm, thereby making the folding of the product smoother (this is common sense in physics and will not be explained here).

[0032] A first fixing buckle 17 is provided at the bottom front end of the seat cushion 3, and a first clipping groove 18 with a bottom opening is provided on the bottom surface of the first fixing buckle 17. The diameter of the first clipping groove 18 matches the outer diameter of the mounting rod 14, and the opening size of the first clipping groove 18 is slightly smaller than the outer diameter of the mounting rod 14. When the first clipping groove 18 is installed on the mounting rod 14, it plays a certain fixing role. When it needs to be folded, the seat cushion 3 is lifted to disengage the first clipping groove 18 and the mounting rod 14. Driven by the hinge 8, the seat cushion 3 continues to flip upward.

[0033] In addition, a clamping block 24 is provided in the first clamping slot 18 . When the first clamping slot 18 is installed on the mounting rod 14 , the clamping block 24 clamps the mounting rod 14 .

[0034] A pad 19 is installed at the bottom of the transverse tube 4, and the bottom surface of the pad 19 is provided with a semicircular groove 20 that matches the pipe diameter of the rear foot assembly 2. The semicircular groove 20 is clamped on the rear foot assembly 2. The function of the pad 19 is to ensure that the seat cushion 3 is in a horizontal state when the product is unfolded. In addition, the semicircular groove 20 and the rear foot assembly 2 also have a positioning and fixing effect. In conjunction with the first clamping groove 18 and the mounting rod 14 (the axis center line of the semicircular groove 20 and the axis center line of the first clamping groove 18 are perpendicular to each other), it can effectively ensure that the seat cushion 3 will not move, thereby further improving the safety of use.

[0035] The backrest bracket 5 is symmetrically provided with rotatable and foldable armrests 21 to further reduce the volume after folding and the space occupied when stored.

[0036] The backrest bracket 5 is provided with a height-adjustable pillow 22 , which can better fit people of different body shapes.
