Description

Technical Field

[0001] This utility model relates to the field of shower chair technology, specifically to a shower chair designed to prevent accidental falls. Background Technology

[0002] A shower chair is an assistive device designed for people with limited mobility (such as the elderly, people with disabilities, or people recovering from surgery) to provide safety support while showering or taking a bath and prevent slipping or falling.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] Although the existing technology has a strut structure, the strut structure does not have a limiting function, which causes the strut to rotate too much. In daily use, when the chair seat is pulled down, the strut tends to tilt forward, causing one end of the strut to fail to contact the wall and fail to form a triangular support structure. This causes the chair seat to tilt, making it easy for people to fall off the chair. Utility Model Content

[0005] The purpose of this invention is to provide a shower chair that prevents accidental falls, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shower chair designed to prevent accidental falls, comprising a chassis, bolt holes through the side of the chassis, a protective cover movably fitted over the chassis, a first connecting rod hinged to one side of the chassis, an extension rod fitted to one end of the first connecting rod, a chair cover fitted over the extension rod, and a bent tube fitted to the other end of the extension rod. The chassis, protective cover, first connecting rod, extension rod, and bent tube are symmetrically distributed about the horizontal center line of the chair cover, and support rod assemblies are fitted to the opposite sides of the two bent tubes.

[0007] The support rod assembly includes a handle, which has a T-shaped structure. One end of the handle is fitted with a support rod, and one end of the support rod is fitted with a rotary damper, which also has a T-shaped structure. One end of the rotary damper is rotatably connected to a connecting rod.

[0008] A limiting groove is provided on one inner wall of the rotary damper, and a limiting block is provided on the outer wall of the sleeve rod near the rotary damper. The outer wall of the limiting block is movably sleeved with the inner wall of the limiting groove. The limiting block and the limiting groove are symmetrically distributed about the end face of the sleeve rod.

[0009] The beneficial effects of this utility model are as follows: With the combination of handle, support rod, rotary damper and connecting rod, the shower chair can be quickly unfolded and form a stable triangle with the wall and support rod. The entire device is installed at a height where the chair cover is perpendicular to the wall and the handle is stably against the wall, thereby improving the stability of the entire device to prevent the user from falling. With the cooperation of the limiting groove and limiting block, the angle of rotation of the support rod can not exceed 90 degrees. During the process of flattening the shower chair, the support rod hangs down naturally so that the support rod, chair cover and wall can form a stable triangle, preventing the chair surface from tilting and the person from falling.

[0010] To ensure that the struts can form a stable support surface with the chair cover:

[0011] The grip, strut, and rotary damper are further configured such that their lengths are greater than the lengths of the first connecting rod, extension rod, and bend assembly.

[0012] By adopting the above technical solution, the chair cover can be kept perpendicular to the wall when the handle and support rod are rotated at a certain angle.

[0013] To ensure that the bottom of the support rod has sufficient support surface and that the structure formed by the support rod, rotation damper, and bend is sufficiently stable:

[0014] The grip, support rod, rotary damper, and bend form an I-shaped structure, and the entire assembly of the grip, support rod, and rotary damper is aligned with the horizontal center line of the chair cover.

[0015] By adopting the above technical solution, the overall structure of the handle, support rod, rotation damper and bend tube is stabilized, and the chair cover can stably support the human body when unfolded.

[0016] To allow the shower chair to be lowered or placed against the wall as needed:

[0017] The following configuration is further provided: the first connecting rod can rotate around the chassis in the vertical direction so that the chair cover is perpendicular to the mounting wall, and the support rod can rotate around the rotation damper at a certain angle so that the handle abuts against the mounting wall.

[0018] By adopting the above technical solution, the first connecting rod can rotate around the chassis, which can realize the flat placement of the shower chair and its operation against the wall, making it convenient to use and not taking up too much space.

[0019] To achieve an ergonomic design for the shower chair and facilitate drainage:

[0020] The chair cover is further configured such that a number of drainage holes are provided through the top of the chair cover, and the cross-section of the chair cover is an arched structure.

[0021] By adopting the above technical solution, the arched chair cover can better fit the curve of the human hip, and several drainage holes are provided to facilitate drainage and cleaning.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0031] Please see Figures 1 to 5 A shower chair designed to prevent accidental falls includes a chassis 1. Bolt holes are provided through the side of the chassis 1. A protective cover 2 is movably fitted over the chassis 1. A first connecting rod 3 is hinged to one side of the chassis 1. An extension rod 4 is sleeved at one end of the first connecting rod 3. A chair cover 5 is sleeved over the extension rod 4. A bent tube 6 is sleeved at the other end of the extension rod 4. The chassis 1, protective cover 2, first connecting rod 3, extension rod 4, and bent tube 6 are symmetrically distributed about the horizontal center line of the chair cover 5. Support rod assemblies 7 are sleeved on opposite sides of the two bent tubes 6.

[0032] The support rod assembly 7 includes a handle 701, which has a T-shaped structure. One end of the handle 701 is sleeved with a support rod 702, and one end of the support rod 702 is sleeved with a rotary damper 703. The rotary damper 703 has a T-shaped structure, and one end of the rotary damper 703 is rotatably connected to a sleeve rod 704.

[0033] A limiting groove 705 is provided on one inner wall of the rotary damper 703, and a limiting block 706 is provided on the outer wall of the sleeve rod 704 near the rotary damper 703. The outer wall of the limiting block 706 is movably sleeved with the inner wall of the limiting groove 705. The limiting block 706 and the limiting groove 705 are symmetrically distributed about the end face of the sleeve rod 704.

[0034] In this embodiment, as Figure 5 As shown, the lengths of the grip 701, support rod 702, and rotary damper 703 are greater than the combined lengths of the first connecting rod 3, extension rod 4, and bend 6.

[0035] In this embodiment, as Figure 3 and Figure 5 As shown, the handle 701, support rod 702, rotary damper 703 and bend 6 form an I-shaped structure, and the whole assembly of the handle 701, support rod 702 and rotary damper 703 is aligned with the horizontal center line of the chair cover 5.

[0036] In this embodiment, as Figure 4 As shown, the first connecting rod 3 can rotate around the chassis 1 in the vertical direction so that the chair cover 5 is perpendicular to the mounting wall, and the support rod 702 can rotate around the rotation damper 703 at a certain angle so that the handle 701 abuts against the mounting wall.

[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the chair cover 5 has several drainage holes, and the cross-section of the chair cover 5 is an arched structure.

[0038] The working process of this shower chair designed to prevent accidental tipping is as follows:

[0039] During installation, the support rod 702 is unfolded around the rotary damper 703 (model: Y13D0-B301). The limiting block 706 of the sleeve rod 704 rotates within the limiting groove 705 on one side of the rotary damper 703 (model: Y13D0-B301). The limiting groove 705 has a small overall curvature, which allows the support rod 702 to rotate at a small angle in the vertical direction without rotating more than 90 degrees and causing the chair cover 5 to tilt downwards. This improves the limiting and fixing ability of the shower chair itself.

[0040] Make the handle 701 press against the corner of the wall and keep the plane of the chair cover 5 perpendicular to the wall. Drill holes in the wall at the corresponding positions according to the holes reserved on the chassis 1, insert expansion tubes, fix the chassis 1 to the wall with bolts, and put on the protective cover 2 and tighten the appearance screws so that the protective cover 2 provides waterproof protection for the chassis 1 components.

[0041] A set of first connecting rods 3, extension rods 4 and bends 6 are respectively connected to the support rod assembly 7 to form a U-shaped structure, ensuring that the support rod assembly 7 is located at the center line of the structure, and a chair cover 5 is fitted between a set of extension rods 4.

[0042] When not in use, the chair cover 5 is flush with the wall, and the handle 701 and support rod 702 are in close contact with the bottom of the chair cover 5. When in use, rotate the chair cover 5 along the hinged base 1 to a position perpendicular to the wall, and rotate the handle 701 and support rod 702 around the rotation damper 703 (model: Y13D0-B301) until the handle 701 abuts against the corner of the wall, so that the whole forms a stable triangular structure. The middle of the chair cover 5 is arched to fit the curve of the human buttocks, and several drainage holes are provided through it.
