Description

Technical Field

[0001] The present application relates to an auxiliary tool for bathing, in particular to a bathing chair with a wall-mounted design that can be quickly folded and attached to the wall when not in use, occupying little space and being convenient for storage. Background Art

[0002] A "bathing assistance component" is proposed in a Chinese Taiwan new patent (certificate number M625458) that has been approved. Its structure includes a wheelchair frame, a support frame, and a seat frame. The wheelchair frame includes a first bearing part and a first connecting part. The support frame includes a second bearing part and a second connecting part. The seat frame is configured to be carried on the first bearing part and detachably connected to the first connecting part. Alternatively, the seat frame is configured to be carried on the second bearing part and detachably connected to the second connecting part. The wheelchair frame includes a frame body and a plurality of rollers. The frame body includes a plurality of legs. The legs are connected to the first bearing part. The rollers are rotatably connected to the legs. However, this bathing assistance component is basically assembled by connecting many frame bodies to each other and cannot be folded, which is not conducive to storage and requires a large storage space.

[0003] In addition, a "bathing chair" is proposed in a Chinese Taiwan new patent (certificate number M513694) that has been approved. A seat part is pivotally connected to the backrest of the chair body of the chair, and the rear chair legs are fixedly connected to the backrest. The front chair legs are pivotally connected to the seat part, and an armrest is pivotally connected to the side of the backrest. A flushing unit is attached to the chair body and connected to a water supply unit. When a person with limited mobility or slow movement wants to take a bath, they can sit on the seat part, and then the control unit provided on the chair body drives the water supply unit to discharge water through the flushing unit for cleaning. After taking a bath, the armrest can be turned up to the side of the backrest, the front chair legs can be turned to lean against the bottom side of the seat part, and the seat part can be turned up to be attached to the backrest. In this way, the armrest, seat part, and front chair legs are concentrated and folded at the backrest, effectively reducing the overall volume and achieving the effect of not occupying space and being convenient for storage. Although the above bathing chair is equipped with a flushing unit and the armrest, seat part, and front chair legs can be folded at the backrest to effectively reduce the overall volume, it is inconvenient to use because the armrest, seat part, and front chair legs need to be folded one by one.

[0004] In addition, a "bathing flushing device group" is proposed in a Chinese Taiwan design patent (certificate number D226940) that has been approved. A bathing chair fixed to the wall is proposed, and its armrest and seat surface can be folded and attached to the wall. However, when folding, the armrest and seat surface still need to be folded separately one by one, which is inconvenient to use. Summary of the Utility Model

[0053] In the following implementation manners, the positional relationships described include: up, down, left, and right. Unless otherwise specified, they are all based on the directions in which the components are shown in the drawings.

[0054] First, please refer to Figure 1 and Figure 2, showing a schematic structural diagram and an exploded view of a preferred embodiment of the bathing chair of the present application. The bathing chair of the present application can be installed on the wall surface W or an upright surface and can be folded and leaned against the wall surface W or the upright surface when not in use (see Figure 5 ), which can reduce the storage space occupied by the bathing chair.

[0055] The structure of a preferred embodiment of the bathing chair of the present application basically includes: a fixing plate 10, a movable seat surface 20, a chair leg 30, and a chair leg connecting rod 40. Among them, the fixing plate 10 is installed at a fixed position on the wall surface W or the upright surface through a plurality of connecting components 11 (such as expansion screws, see Figure 7 ).

[0056] The movable seat surface 20 is pivotally connected to the fixing plate 10 through a rotating shaft mechanism at the rotation point A (see Figure 5 ), and the movable seat surface 20 freely rotates around a rotation axis at a rotation point A to a use position (see Figure 1 and Figure 8 ) and a non-use position (see Figure 9 ). When in the use position, the user can sit on the movable seat surface 20. When in the non-use position, the movable seat surface 20 is leaned against the wall surface W or the upright surface, which can reduce the storage space occupied by the bathing chair.

[0057] Please refer to Figure 1 , Figure 6 and Figure 7 . A preferred embodiment structure of the rotating shaft mechanism includes: a non-circular shaft 50 (see Figure 6 ), and a non-circular shaft tube 60 (see Figure 7 ); in an exemplary structure shown in Figure 1 and Figure 6 , the non-circular shaft 50 is fixedly installed on the fixing plate 10 in a non-rotatable manner, and the non-circular shaft tube 60 is fixedly arranged on one side edge of the movable seat surface 20; in a preferred embodiment, a shaft seat 12 is fixedly arranged on the upper edge of the fixing plate 10. In a preferred implementation manner, there are two shaft seats 12 respectively fixedly arranged on both sides of the upper edge of the fixing plate 10. The shaft seat 12 is a kind of non-circular tube, the inner diameter of the shaft seat 12 engages with the non-circular shaft 50, and the non-circular shaft 50 passes through the shaft seat 12, and the non-circular shaft 50 is fixedly installed on the fixing plate 10 in a non-rotatable manner through the shaft seat 12.

[0058] Among them, the non-circular shaft 50 has an upper stop surface 51 and a lower stop surface 52. The upper stop surface 51 and the lower stop surface 52 are an "incomplete axial section", and the shape of the "incomplete axial section" is different from the shape of the "complete axial section" of a general circular shaft. The "incomplete axial section" is located on one side of the axis, which means that the "incomplete axial section" is smaller than the "complete axial section", especially less than 1 / 2 of the "complete axial section"); the cross-sectional shape of the shaft seat 12 is consistent with the cross-sectional shape of the non-circular shaft 50. The shaft seat 12 has a first section 121 and a second section 122 (see Figure 7 ). The non-circular shaft 50 penetrates into the shaft seat 12. The upper stop surface 51 of the non-circular shaft 50 contacts the first section 121, and the lower stop surface 52 of the non-circular shaft 50 contacts the second section 122, fixedly installing the non-circular shaft 50 on the fixing plate 10 in a non-rotatable manner.

[0059] The non-circular shaft tube 60 is fixed to one side edge of the movable seat surface 20 and has a non-circular shaft hole 61 penetrating through the axis of the non-circular shaft tube 60. The non-circular shaft hole 61 has a first stop surface 611 and a second stop surface 612. When the movable seat surface 20 rotates to the use position, the first stop surface 611 contacts the upper stop surface 51 (see Figure 8 ), thereby making the movable seat surface 20 stop at the use position. When the movable seat surface 20 rotates to the non-use position (see Figure 9 ), the second stop surface 612 contacts the lower stop surface 52, thereby making the movable seat surface 20 stop at the non-use position.

[0060] A preferred embodiment of the chair leg 30 is a U-shaped tube structure; a preferred embodiment structure of the chair leg 30 includes: a horizontal tube 31 and vertical tubes 32 connected to both ends of the horizontal tube 31. The horizontal tube 31 extends in the horizontal direction. The horizontal tube 31 is rotatably pivotally connected to a pivot seat 33, and the pivot seat 33 is fixedly installed on the bottom surface of the movable seat surface 20; in a preferred embodiment, the axis of the vertical tube 32 intersects with the axis of the horizontal tube 31, for example, perpendicularly intersects, but not limited thereto. The included angle between the axis of the vertical tube 32 and the axis of the horizontal tube 31 can also be greater than 90 degrees; the chair leg 30 can freely rotate to a support position (see Figure 5 ) and a storage position (see Figure 1 ) with the pivot seat 33 as the rotation point B (see Figures 3 to 5) At the support position, the chair leg 30 is used to support the weight of the movable seat surface 20 and the human body. That is, when the chair leg 30 rotates to the support position, the vertical pipe 32 extends in the direction towards the ground, and at the storage position, the chair leg 30 is close to the bottom surface of the movable seat surface 20 in the direction towards the wall surface W or the vertical surface; A preferred embodiment structure of the chair leg 30 further includes: a movable foot pad 34, movably connected to the bottom end of the vertical pipe 32. In one embodiment, the movable foot pad 34 has a screw rod 341 screwed to the bottom end of the vertical pipe 32. By rotating the screw rod 341, the length of the movable foot pad 34 extending from the bottom end of the vertical pipe 32 can be adjusted, so that on uneven ground, the chair leg 30 can still make firm contact with the bottom surface to provide a stable and reliable support for the movable seat surface 20.

[0061] One end of the chair leg link 40 is pivotally connected to the rotation point C of the chair leg 30 (see Figure 5 ), the other end of the chair leg link 40 is pivotally connected to the rotation point D of the fixed plate 10. When the chair leg 30 rotates to the support position, it can drive the chair leg link 40 to rotate to an operative position (see Figure 1 ), and when the chair leg 30 rotates to the storage position, it can drive the chair leg link 40 to rotate to an inoperative position (see Figure 5 ); The chair leg link 40 in the operative position is used to temporarily hold the chair leg 30 in the support position, preventing the chair leg 30 from deviating from the proper support position due to the weight of the movable seat surface 20 and the human body, ensuring the safety of use; The chair leg link 40 in the inoperative position is close to the bottom surface of the movable seat surface 20 in the direction towards the wall surface W or the vertical surface.

[0062] A preferred implementation manner is that the chair leg link 40 is generally a U-shaped rod, for example, made by bending a metal rod. The structure of the chair leg link 40 includes: a cross bar 41 and arm rods 42 connected to both ends of the cross bar 41. The cross bar 41 extends in the horizontal direction. The cross bar 41 is pivotally connected to the rotation point D of the fixed plate 10. In a preferred implementation manner, the rotation point D is on the back surface of the fixed plate 10 (facing the wall surface W or the vertical surface). A groove 13 is provided at the position of the rotation point D (see Figure 5 ), and the cross bar 41 is placed in the groove 13 in a loose fit manner; The axis of the arm rod 42 intersects with the axis of the cross bar 41, for example, perpendicularly intersects, but not limited thereto. The end of the arm rod 42 is pivotally connected to the rotation point C of the chair leg 30. In a preferred implementation manner, a pivot hole 35 is provided at the rotation point C of the chair leg 30 (see Figure 2 ), and the end of the arm rod 42 is pivotally inserted into the pivot hole 35.

[0063] Please refer to Figure 1 and Figures 3 to 5, showing a schematic diagram of the use state of the bath chair. The fixed plate 10, the movable seat surface 20, the chair legs 30 and the chair leg connecting rod 40 are pivotally connected to each other rotatably through the rotation points A, B, C and D to form a four-bar linkage mechanism. Among them, the relative positions of the rotation points A and D are fixed. The connecting rods AB and DC of the four-bar linkage mechanism are game rods. When the user flips the movable seat surface 20 to the use position, the chair legs 30 can be linked to rotate to the support position (see Figure 1 ), and when the user flips the movable seat surface 20 to the non-use position, the chair legs 30 can be linked to rotate to the storage position (see Figure 5 ); Therefore, when the user flips the movable seat surface 20, the chair legs 30 and the chair leg connecting rod 40 can be linked to swing, which has the effects of simple operation and convenient use.

[0064] In another preferred embodiment structure of the bath chair of the present application, it further includes: a left armrest 70L and a right armrest 70R. One pivot end of the left armrest 70L and the right armrest 70R is pivotally connected to the rotating shaft mechanism rotatably. The left armrest 70L and the right armrest 70R are respectively located on the left and right outer sides of the movable seat surface 20; in a preferred implementation manner, the pivot end of the left armrest 70L is pivotally connected to the left end of the non-circular shaft 50 rotatably, and the pivot end of the right armrest 70R is pivotally connected to the right end of the non-circular shaft 50 rotatably.

[0065] Please refer to Figure 6 , in a preferred implementation manner, a left shaft sleeve 71L and a right shaft sleeve 71R are respectively fixedly arranged at the pivot ends of the left armrest 70L and the right armrest 70R. The structures of the left shaft sleeve 71L and the right shaft sleeve 71R are the same. For the convenience of description, the left shaft sleeve 71L will be taken as an example below to illustrate the structures of the left shaft sleeve 71L and the right shaft sleeve 71R. The left armrest 70L is pivotally connected to the left end of the non-circular shaft 50 rotatably through the left shaft sleeve 71L. The left armrest 70L can rotate to a first position (see Figure 1 ) and a second position (see Figures 3 to 5 ). In the first position, the left armrest 70L and the right armrest 70R are respectively located on the left and right outer sides of the movable seat surface 20 and extend forward towards the bath chair to support the user's left and right arms. In the second position, the left armrest 70L and the right armrest 70R are close to the wall surface W or the vertical surface; the user can flip the left armrest 70L and the right armrest 70R arbitrarily according to their own needs.

[0066] In a preferred implementation manner, basically the left shaft sleeve 71L can be regarded as the application of a non-circular shaft tube. Please refer to Figure 6, the inner diameter shape of the left bushing 71L is non-circular. The interior of the left bushing 71L has a first stop surface 72 and a second stop surface 73 (the same applies to the right bushing 71R). When the left armrest 70L rotates to the first position, the first stop surface 72 contacts the upper stop surface 51 of the non-circular shaft 50, thereby stopping the left armrest 70L at the first position (the same applies to the right armrest 70R). When the left armrest 70L rotates to the second position, the second stop surface 73 contacts the lower stop surface 52 of the non-circular shaft 50, thereby stopping the left armrest 70L at the second position.

[0067] In a preferred embodiment structure, the bathing chair further includes a backrest 80 to provide support for the user's back. The backrest 80 is fixedly installed on the fixed plate 10, and the back surface of the fixed plate 10 abuts against the wall surface W or the vertical surface; in a preferred embodiment structure, a plurality of cushions 81 are arranged on the back surface of the backrest 80 (the one facing the wall surface W or the vertical surface). In a preferred implementation, the cushions 81 are made of rubber or soft plastic.

[0068] In a preferred implementation, the fixed plate 10, the movable seat surface 20, and the backrest 80 are all components made by plastic injection molding technology. The movable seat surface 20 is composed of two upper components 20U and lower components 20D that can be butt-jointed. The upper component 20U and the lower component 20D are butt-jointed and then connected together by a plurality of bolts or quick buckles to form the movable seat surface 20. The upper surface of the upper component 20U is for the user to sit on. The pivot seat 33 of the chair legs 30 is assembled to the bottom surface of the lower component 20D by bolts or quick buckles; the structure of the fixed plate 10 basically includes two front components 10F and rear components 10R that are butt-jointed. The shaft seat 12 of the fixed plate 10 and the front component 10F are integrally formed by plastic injection molding technology. The front component 10F and the rear component 10R are butt-jointed and then connected together by a plurality of bolts or quick buckles to form the fixed plate 10. The front component 10F is provided with a cover 14 for covering the mounting holes of the connection assembly 11 (see Figure 7 ). The cover 14 is detachably arranged on the front component 10F by hooks, and can hide the connection assembly 11 to make the visual appearance of the fixed plate 10 have a complete beautification effect; the groove 13 on the back surface of the fixed plate 10 is located on the back surface of the rear component 10R.
