Description

[Detailed Description of the Invention] The present invention provides a so-called back seat, that is, a chair.
It was developed to be adapted for shampooing by rotating 180 degrees, then raising the underseat, and tilting the backrest to place the customer in a supine position, with the nape of the customer's neck resting on the neck of the shampoo bowl. This invention relates to a hairdressing chair for bathing.

The above-mentioned backrest is performed in order to allow the customer to sit in a comfortable supine position without forcing the customer to bend forward. The lower part of the seat was hinged directly to the rear of the underseat, and the seat could be tilted and raised using the hinge as a fulcrum. However, in this type of hairdressing chair, when the backrest is tilted, the technician must support it with his hands, and when the backrest is tilted, the back of the customer's clothes are pulled, causing discomfort to the customer. Furthermore, due to the difference in height, there were inconveniences such as the inability to fit into the shampoo bowl.

The present invention has been developed to eliminate the above-mentioned inconveniences, and its purpose is to allow the customer to move into a supine position without the back of their clothes being pulled when the backrest is tilted, and thus without causing any discomfort to the customer. Our goal is to provide you with a hairdressing chair for your bathroom.

Another object of the present invention is to provide a hairdressing chair for shampooing that can softly fit the nape of a customer's neck to the neck portion of a shampoo bowl regardless of height differences, and another object of the invention is to provide a hairdressing chair for shampooing. To provide a hairdressing chair for a bath chair which can raise and lower a footrest at the same time as the chair is tilted.

Still another object of the present invention is to provide a hairdressing chair for shampoos that is mechanically reasonable, can be constructed simply, can be made at a correspondingly low cost, and has a long service life.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a base plate, 1a is a leg for height adjustment provided at the bottom of the base plate 1, 2 is a support plate erected on the base plate 1, and 3 is raised from the support plate 2 via a shaft 4. a hydraulic cylinder provided to be tiltable; 3a is a plunger of the hydraulic cylinder; 5 is a main link in the form of a tilted channel whose base end is pivotally connected via a shaft 6 to be tiltable; 7; indicates a connecting member fixed to the back surface near the tip of the main link 5 (note: to the back surface of the upper plate forming the inverted channel shape);
The connecting member 7 and the tip of the plunger 3a described above are connected via a rotation shaft 8.

Reference numeral 9 indicates a sub-link whose base end is pivotally connected to the support plate 2 via a shaft 10, 11 indicates an undersheet board having an armrest board 12, and a bracket 1 is provided on the rear surface of the undersheet board 11.
3 is fixed to the bracket 13, and the tip of the main link 5 is connected to this bracket 13 via a rotation shaft 14. (See especially Figure 3 in the drawings) Also, sublink 9
A rising plate portion 9a is provided at the tip of the bracket 11.
It is pivotably attached to the lower part of 3.

Thus, the spacing between the axes 6 and 14 is made equal to the spacing between the axes 10 and 15, and the spacing between the axes 6 and 10 is made equal to the spacing between the axes 14 and 15.
5 to form a parallel link mechanism, and the undersheet substrate 11 can be moved up and down and moved forward and backward without changing its posture.

Reference numeral 16 indicates a backrest base plate having a projecting plate 16a at the lower part of the front surface; 17 indicates a footrest rotatably provided on the front part of the underseat base plate 11 via a shaft 19; The shaft 18 is attached to the fixed protrusion 12a.
It is pivoted so that it can be raised and lowered via.

Reference numeral 20 denotes a reciprocating plate, and 21 denotes an arcuate plate. The tip of the arcuate plate 21 is rotatably attached to the upright plate 9a of the sub-link 9 via a shaft 23, and the rear end of the arcuate plate 21 is rotatably attached to the projecting plate 16a of the backrest base plate 16 via a shaft 24. It is pivoted so that it can move.

Next, to explain its function, when the backrest base plate 16 is upright and the footrest 17 is hanging down as shown in FIG. , the main link 5 is tilted slightly upward through the connecting member 7 and the rotation shaft 8, with the shaft 6 as a fulcrum as shown in FIG. That is, it rotates steplessly in a clockwise direction about the shaft 6 as a fulcrum, and assumes a nearly vertical state as shown in FIG.

As the plunger 3a moves forward, the undersheet substrate 11 goes through the state shown in FIG. 2 via the bracket 13 fixed to the undersheet substrate 11 and the rotating shaft 14, and then rises without changing its posture as shown in FIG. 3. and moves forward to the right in the drawing, and on the other hand, as the sub-link 9 rises, the rising plate portion 9a moves toward the shaft 10.
The rising plate portion 9a rotates clockwise using the fulcrum.
The arcuate plate 21 and the reciprocating plate 20, which are pivotally connected to the upper end of the shaft 23, are displaced to the right.

Due to the rightward displacement of the arcuate plate 21, the backrest board 16, which is pivotally attached to the arcuate plate 21, tilts rearward about the shaft 18 as a fulcrum.

Further, as the reciprocating plate 20 is displaced to the right, the footrest 17 pivoted to the reciprocating plate 20 rotates upward about the shaft 19 as a fulcrum.

Thus, the plunger 3 of the hydraulic cylinder 3
At the stroke end of a, the shape shown in FIG. 3 is maintained and stopped.

By further retracting the plunger 3a, the plunger 3a operates in the opposite manner to the above and returns to its original position. Further, the base plate 1 is moved up and down by rotating the legs 1a to the right and left according to the height of the shampoo bowl.

Since the present invention is constructed as described above, the backrest rises and falls as the undersheet board moves up and down and advances and retreats, so that the back of the customer's clothes is not pulled unilaterally as if the backrest were to fall down by itself. In addition, by allowing the backrest to recede and fall down in synchronization with the upward movement of the underseat, differences in height can be well absorbed, and the footrest can be softly fitted to the neck of the shampoo bowl, and in this case, the footrest naturally rises. As a result, the posture becomes even more comfortable, and furthermore, it is mechanically reasonable and can be constructed simply, resulting in lower costs and a longer service life.
