[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back washer for easily washing the back in the bathroom.

[0002]

2. Description of the Related Art Up to now, towels, hand towels, nylon scrubs, sponges, etc. have been used as tools for washing the entire body and back when taking a bath.

[0003]

Conventionally, in the case of a towel-like cleaning tool, a method of holding both ends of the cleaning tool and rotating it around the back to wash the back has been widely used. However, even with such a method, when washing the entire back, the arm has to be repeatedly moved in the left and right directions while tilting the arm obliquely upward or downward, or while maintaining the height, and twisting and muscle strength of each joint of the arm are required. For this reason, for the elderly with a stiff body or the disabled or injured who cannot move their arms freely,
Such a washing method is also unreasonable, and there is a problem that these persons cannot wash their backs easily and sufficiently with the conventional washing tools.

[0004]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention proposes a swing lever (22) having a base end portion swingable left and right on the back side of a bath bowl (1). A cleaning mat (26) made of a water-resistant elastic member is attached to the upper front side of the rocking lever (22), and the operating lever (2) for rocking the rocking lever (22) is attached. It is characterized in that the base end is axially supported on the side surface of the bath (1).

[0005]

In the back washing device of the present invention, the bather seated in the bath chair 1 facing forward grasps the operation lever 2 located on the side and manually swings back and forth to swing the swing lever. 22 swings in the left-right direction about the fulcrum shaft 8 at the base end, and the mat 26 also swings in the left-right direction. For this reason, a bather who sits on the bath chair 1 and has his back on the front of the mat 26 simply operates the operation lever 2
It becomes possible to wash the entire back surface only by performing the rocking motion of.

[0006]

EXAMPLES The examples shown below will be described in detail below. A hollow box-shaped bath using a plastic material is used.
The base ends of the operation levers 2 and 2 are pivotally supported on the side walls 1b and 1b by shafts 3 and 3 so that the operation levers 2 and 2 are connected to the shaft tube 4 via the shafts 3 and 3. The shaft tube 4
A gear 6 is fitted to the shaft tube 4 so as to rotate integrally therewith. A gear 7 that meshes with the gear 6 and rotates at the same time is fitted and supported at the tip of the fulcrum shaft 8 so as to rotate integrally with the fulcrum shaft 8. The fulcrum shaft 8 has a bearing 10 and a rear surface. It is rotatably supported by the wall 1a. on the other hand,
A fulcrum shaft 9 is rotatably supported by a fulcrum shaft 8 side by side with the fulcrum shaft 8 via a bearing 11 on the back wall 1a of the chair. The arm 14, on the upper surface of the peripheral wall on the inner side of the chair of the fulcrum shafts 8 and 9,
14 are attached in the vertical direction, and both ends of a stay 15 in the left-right direction are rotatably supported on the upper ends of the arms 14 by a shaft 18, a washer, and a nut.
The stay 14 and the stay 15 are structured to swing while forming a tuning link.

The fulcrum shafts 8 and 9 projecting outward from the back wall 1a of the chair have pivotally supported base ends of vertically oriented lever holders 20 and 20, respectively. The lever holders 20 and 20 are provided at their upper end portions with lever-like insertion openings 21 and 21 which are open in a cylindrical shape.
The lower ends of the rocking levers 22, 22 are inserted into and fitted into the Nos. 1, 21 from above, respectively, to be supported. Swing lever 22,
Both ends of a left-right stay 23 are rotatably supported by shafts 24, 24 and washers and nuts on the front side of the upper end of 22, and the lever holders 20, 20 and the swing levers 22, 22 constitute parallel links. And swing left and right together. Further, a rectangular plate-shaped mat base 25 is fixed to the front side of the stay 23, and a mat 26 having a constant thickness and made of a water-resistant foam material having elasticity is fixed to the front side of the mat base 25. A rubber rubber 28 having a large number of spherical protrusions 27 is attached to the surface of the mat 26 while being attached to the entire surface. The groove 30 is provided as a recess and the peripheral surface of the groove 30 is the mat 2
A rod-shaped submerged material 31 made of a water-containing elastic material such as a sponge is removably housed so as to project from the front surface of 6.

With such a structure, the fulcrum shafts 8, 9 and the lever holder 20, via the shaft tube 4, the gear 6, the gear 7 and the tuning link, as the operating levers 2, 2 swing in the longitudinal direction.
The mat 26 repeats the left-right swinging motion by interlocking the respective parts of the swing lever 20 and the swing levers 22, 22.
The surface of the mat 26 moves left and right while being pressed against the back of the bather, so if water and detergent are soaked in the submersible material 31 formed of the impregnating material beforehand, Through the friction between the submerged material 31 and the surface of the mat 26, the detergent is dispersed on the entire surface of the mat 26. Matte 26
Since the spherical projections 27 formed on the surface make the surface of the mat 26 uneven, the foaming of the detergent is improved, the cleaning ability when the mat 26 slides is improved, and the stimulus received by the user is also comfortable. Becomes

In the present invention, the gears 6 and 7 can be provided with a gear shifting function in order to change the rocking speed of the mat with respect to the rocking of the operation levers 2 and 2 at a constant speed. Further, in the present embodiment, the case where both the operation lever 2 and the swing lever 22 are described has been described, but it is possible to use one operation lever 2 or one swing lever 22. is there. When the number of rocking levers 22 is one, it is desirable to attach the mat base 25 to the rocking levers 22 at two locations. Also, the bath board 1 and the bottom plate 3
2 can also be attached. In addition, the mat part has the swing lever 22 of the insertion type as described above,
When it is not used as a cleaning tool, it can be used as an ordinary bath chair by removing the mat part.

[0010]

[Effect of the Invention] Since the present invention is constructed as described above, a bather seated in a bath chair can hold his / her operating lever on the side while seated and swing it back and forth on a mat located behind him. There is an advantage that the entire back can be washed easily and surely just by pressing. Therefore, towels, hand towels,
Compared to washing your back with nylon scrubbing or sponge, you do not have to twist or twist your arms, but you also need to bend both arms diagonally upward or downward, and bend them. The effect of being able to wash the entire back surface evenly while eliminating the need to move it from side to side while wearing it.
