Accordingly, when the projection 2b ₂ is displaced in accordance with the undulation of the backrest 2b, the rotation axis of the potentiometer 11 is rotated via the two-stage link 12, so that the resistance value changes in accordance with the undulation angle of the backrest 2b. Therefore, by detecting the change in the resistance value, the undulation angle of the backrest 2b can be detected.
[0019]
13 stretched been backrest return spring between the pin 4d attached to the connecting plate 14 and the seat substrate 4 is supported by a protrusion 2b ₂ in the backrest 2b, 15 is of the extruded links 10 is formed in the slide rod 10b a shaft 10b ₁ and in the apron return spring which is stretched between the connecting plate 14, the when moving the Fuku倒direction and upright direction of the apron of the backrest 2b springs 13, 15 operates. The springs 13 and 15 are shown only in FIG. 1 to simplify the drawing.
[0020]
Next, the operation will be described based on the above-described configuration. In FIG. 1, the backrest 2b and the front hanging member 3 which are the initial states are in the upright state, and the seat 2a is at the lowest position. In this state, the subject is seated and the treatment is performed. However, in transition to a state in which the subject is laid down by shaving or the like, that is, a state in which the backrest 2b and the forward slant 3 fall down, It is necessary to set the length of the push-out link 10 in advance depending on whether there is a sufficient distance from the front plumbing device or the wall.
[0021]
By changing the length of the push-out link 10, as described later in detail, the falling angle of the hang 3 changes, so that the amount of protrusion of the hang 3 forward changes. It can be adapted to the length of the gap with the wall.
[0022]
First, a case will be described in which there is a sufficient space between the front hanging 3 shown in FIG. 3 and the plumbing device or the wall surface, and the front hanging 3 can fall down to a substantially horizontal state with the seat 2a.
In this case, the pin 10d is inserted into the hole 10a ₁ (the _one closer to the front sag 3) on the distal end side of the cylindrical link 10a of the push-out link 10. As a result, the amount of protrusion of the slide rod 10b inserted into the cylindrical link 10a from the cylindrical link 10a increases, and the length of the push-out link 10 becomes the maximum length.
[0023]
When the oil in the hydraulic unit 5 is discharged from the chair set in this manner, the spring force of the spring 13 and the weight of the backrest, and the spring force of the spring 15 until the slide rod 10b comes into contact with the pin 10d, are used. The piston in the unit 5 contracts, and the backrest 2b is rotated in a counterclockwise direction. The projection 2b ₂ moves the pushing link 10 rightward with the counterclockwise rotation of the backrest 2b, so that the guide 2b is guided via the projection 10c pivotally supported by the tip of the slide rod 10b in the pushing link 10. Since a turning force acts on the metal fitting 6, the guide metal fitting 6 rotates counterclockwise about the shaft 6a to rotate the front hanging 3 horizontally.
[0024]
When the protrusion 10c of the push-out link 10 moves in the long hole 7a of the connecting link 7 and comes into contact with the tip of the long hole 7a, the connecting link 7 is rotated in a counterclockwise direction. By moving to the right, the guide plate 8 is moved along the guide rail 6b toward the lower end of the front hanging 3. As a result, the front hanging 3 is rotated in the horizontal direction while moving forward.
[0025]
When the projection 2b _{2 of the} backrest 2b is rotated, the potentiometer 11 is rotated via the two-stage link 12, so that a change in the resistance value of the potentiometer 11 is detected by a control circuit (not shown). When the resistance value of the potentiometer 11 reaches the set value, the control of the hydraulic unit 5 is stopped, so that the backrest 2b and the hang-down 3 stop falling. In this state, the front hanging portion 3 is substantially flush with the seat portion 2a, and the leading end projects most.
[0026]
In order to displace the backrest 2b and the front hanging member 3 from the down state to the upright state, when oil is supplied to the hydraulic unit 5, the spring force of the spring 13, the weight of the backrest, and the guide plate 8 abuts against the vertical portion 2e ₁ of the stand 2e, the slide rod 10b is backrest 2b against the spring 15 when away from the pin 10d is is rotated in the standing direction. Further, since the cylindrical link 10a of the push-out link 10 moves rightward with the rotation of the backrest 2b in the rising direction, the slide rod 10b moves into the cylindrical link 10a by the spring force of the spring 15, Therefore, the drooping 3 is displaced in the rising direction by the operation opposite to the above-described operation, and finally the supply of oil to the hydraulic unit 5 from the control circuit that has detected the output from the potentiometer 11 is stopped, It returns to the position (initial position) in FIG. 1 and stops.
[0027]
In the case where an external force opposite to the rising direction is applied to the hanging 3 due to the presence of foreign matter on the back side of the hanging 3 during the return to the initial position, the rising direction of the hanging 3 Is returned only by the spring force of the spring 15, that is, since the slide rod 10b can move within the cylindrical link 10a, the forward slant 3 stops at the position where the external force is applied. .
[0028]
The above-described operation has been described in the case where there is a sufficient space between the hang 3 and the plumbing device or the wall surface. However, when the space is not so large, the pin 10d is connected to the cylindrical link 10a as shown in FIG. by inserting the middle hole 10a _1, since the length of the extrusion link 10 is shortened, Fushimi tilt angle of the apron 3 is smaller than the position of FIG. 3 described above, therefore, the amount of protrusion of the apron 3 is reduced Therefore, it does not come into contact with plumbing equipment or wall surfaces.
[0029]
Further, FIG. 5 shows the case where the narrow gap between the apron 3 and plumbing equipment and walls, the length of the extrusion link 10 by inserting the pin 10d on the rear end side of the hole 10a ₁ of the tubular link 10a FIG. 6 shows a case in which the distance between the hanging 3 and the plumbing device or the wall surface is smaller than that in FIG. 5, and the slide rod 10b is connected to the cylinder without inserting the pin 10d. It is located at the innermost end of the shape link 10a, and the length as the push-out link 10 is further reduced. The operation is the same as the operation in FIG.
[0030]
By reducing the length of the push-out link 10 as described above, the falling angle of the front hanging 3 becomes smaller as shown in the respective drawings (FIGS. 4, 5 and 6). The distance between the tip of the device and the plumbing device or wall surface can be widened.
[0031]
In the embodiment described above, the position of the holes 10a ₁ formed in a cylindrical shape link 10a in the extrusion link 10, but in which the length of the extrusion link 10 has been determined, fine adjustment of more long 7, the screw 16 is screwed into the tip of the slide rod 10b which is inside the cylindrical link 10a, and the length of the slide rod 10b is changed by changing the amount of protrusion of the screw 16 as shown in FIG. Therefore, the falling angle of the forward slump 3 can be freely adjusted. The description of the operation is the same as that of FIG.
[0032]
In any of the above-described embodiments, the push-out link 10 allows the slide rod 10b to be freely inserted into and removed from the cylindrical link 10a, and when the external hanging force is applied to the vertical hanging-back 3 in the rising direction, the vertical hanging-down of the vertical hanging-down 3 is performed. The rotation cannot be performed, thereby preventing the foreign matter or the like from being damaged. However, since such an external force is rarely applied, the length of the push-out link 10 is adjusted. Is possible, but may be integrated at the time of return of the front hanging 3 in the rising direction.
[0033]
FIGS. 8 and 9 show such an embodiment. FIG. 8 shows a case where the cylindrical link 10a of the push-out link 10 in the previous embodiment is a screw rod 17a and the slide rod 10b is a shaft rod 17b. , in which is screwed a screw 17a ₁ of the threaded rod 17a into the screw hole 17c ₁ of the rotatable threaded tube 17c relative to the shaft rod 17b. With such a configuration, the screw 17a ₁ rotates a screw tube 17c is increased as the extrusion link 17 if so enters the screw tube 17c, also screw 17a ₁ on the contrary to protrude from the screw tube 17c By doing so, the pushing link 17 becomes longer. In addition, with this structure, the length of the push-out link 17 can be adjusted steplessly.
[0034]
In the embodiment of FIG. 9, the shaft rod 17b in the embodiment of FIG. 8 is also replaced by a screw rod 17d, and the direction of the screw is opposite to that of the screw rod 17a. Then, those screwed to the threaded rod 17a, each screw _17a 1, 17d screw tube 17e which screws _17e 1, 17e ₂ formed on both sides to _one 17d. With such a configuration, by rotating the screw pipe 17e, the length of the push-out link 17 changes, and the length can be adjusted steplessly.
[0035]
The structure for changing the length of the push-out link is not limited to the above-described embodiment, and any structure having a structure capable of adjusting the length can be used for the push-out link of the present invention. Of course.
[0036]
