DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a relaxation chair according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a seat substrate on which a seat portion 2 divided in two in the front-rear direction is attached, and a guide rail 1a is attached along the front-rear direction. A side surface of the front sag 4 divided into two is attached to the seat portion 2 via a plate (not shown) attached to the back side. Reference numeral 3 denotes a decorative pipe as a design attached from the seat portion 2 along the side surface of the front sag 4.
[0012]
Reference numeral 5 denotes a frame in which a pair of rollers 5a guided by the guide rail 1a are attached to both side surfaces, and arc-shaped guide holes 5b are formed on the same side as the rollers 5a are attached. Reference numeral 6 denotes a longitudinal movement motor having a reduction gear 6a attached in front of the frame body 5, and a forward / backward movement screw shaft 7 is screwed to the reduction gear 6a. Reference numeral 8 denotes a moving plate fixed to the back surface of the seat substrate 1, and the screw shaft 7 is screwed onto the tip of the forward / backward movement screw shaft 7 in a rotatable state.
[0013]
Reference numeral 9 denotes a fixing plate having left and right upright portions 9b to which a pair of rollers 9a guided by guide holes 5b formed on both sides of the frame body 5 are attached, and 10 is fixed to a backrest side of 5 described later. A reduction plate 12 a of a tilting motor 12 is attached to the rotation plate 10 as a rotation plate that is pivotally supported by a U-shaped attachment plate 11.
[0014]
A tilt screw shaft 13 is screwed to the speed reducer 12a of the tilt motor 12, and one end of the tilt screw shaft 13 rotates with respect to a leg plate 14a fixed to a leg 14 installed on the floor surface. Although it is impossible, it is attached via the shaft attachment plate 13a so that the rotation is possible. The fixing plate 9 is also attached to the leg body 14 via a leg plate 14a. The leg body 14 is configured by bending a pipe.
[0015]
Reference numeral 15 denotes a backrest support rod obtained by bending two pipes, one end of which is attached to both ends on the back side of the frame body 5, and an upper backrest 16 that is divided vertically is attached to the tip side. In addition, the upper surface of the lower backrest 17 is rotatably attached to the lower surface of the upper backrest 16. In addition, 18 is rotatably attached to the upper surface of the backrest 17, and can be fixed at two positions on the upper and back sides of the upper backrest 16.
[0016]
Reference numeral 19 denotes a link body fixed at one end to the center of the back surface side of the seat substrate 1, and one end of an auxiliary plate 19a is rotatably attached to the other end. The other end of the auxiliary plate 19 a is pivotally supported on the lower surface of the lower backrest 17.
[0017]
Although not shown, a detecting means is provided for detecting the amount of rotation of the forward / backward movement motor 6 and the tilting motor 12, that is, the amount of movement of the forward / backward movement screw shaft 7 and the tilting screw shaft 13. The rotations of the motors 6 and 12 are stopped when the screw shafts 7 and 13 reach the preset positions.
[0018]
Next, based on the above-described configuration, the operation will be described in an initial state, that is, a state in which the person to be treated is introduced into the relaxation chair of the present invention together with FIGS.
[0019]
In the initial state, the fixed plate 8 is located at the tip of the forward / backward movement screw shaft 7, and the tilt motor 12 is located at the tip of the tilt screw shaft 13. Accordingly, the seat substrate 1 is positioned behind the leg body 14 and the lower backrest 17 is positioned in parallel with the upper backrest 16.
[0020]
In this state, since the seated patient's sitting height is high, when the person's head is above the pillow 18, the seat 2 is moved forward so that the head corresponds to the pillow 18. It is necessary to do so. Therefore, when the longitudinal movement motor 6 is driven, the longitudinal movement screw shaft 7 acts to move to the left as shown in FIGS. 9 and 10 via the speed reducer 6a.
[0021]
The movement of the forward / backward movement screw shaft 7 causes the movement plate 8 attached to the tip of the forward / backward movement screw shaft 7 to move to the left, so that the seat substrate 1 attached to the movement plate 8 becomes a frame. Since the roller 5a moves relative to the body 5 relative to the guide rail 1a, the roller 5a moves leftward (forward).
[0022]
Further, since the seat substrate 1 moves forward, the link body 19 having one end attached to the seat substrate 1 moves forward together with the seat substrate 1, so that the auxiliary plate pivotally supported by the link body 19 is supported. Since the lower backrest 17 attached to the auxiliary plate 19a is pulled forward, the lower backrest 17 is rotated clockwise with the lower surface of the upper backrest 16 as a branch, and accordingly, the lower backrest 17 attached to the auxiliary plate 19a is pulled forward. The gap between the seat portion 2 and the upper back 18 caused by the advancement of the seat portion 2 is closed, and the waist portion of the seated patient is received (see FIG. 4). Since the seat 2 and the front sag 4 are integrally attached, the front sag 4 advances together with the seat 2.
[0023]
Next, an operation of shifting the seat portion 1, the front sag 4 and the backrests 16 and 17 from the initial state to the state of relaxation in the tilted state will be described with reference to FIGS.
When the tilt motor 12 is driven in the initial state, the tilt screw shaft 13 acts to move to the right as shown in FIGS. 11 and 12 via the speed reducer 12a.
[0024]
However, since the tilt screw shaft 13 is pivotally supported on the leg 14 side and the speed reducer 12a is fixed to the rotating plate 10, the mounting plate 11 is counteracted by the action of the tilt screw shaft 13. Is applied with a rotational force in the clockwise direction due to the relationship with the rotating plate 10, and the rotational force in the clockwise direction is also applied to the frame 5 by this rotational force.
[0025]
At this time, the roller 9a attached to the fixed plate 9 moves through the arcuate guide hole 5a of the frame 5, so that the entire frame 5 is rotated clockwise and the fixed plate 11 in the clockwise direction. It will turn around the pivot point. Accordingly, since the seat substrate 1 attached to the frame 5 is rotated clockwise, the seat 2 is inclined with the waist side down and the foot side up, and the back of the frame 5 is The backrests 16 and 17 attached via the heel support rod 15 are also tilted backward while maintaining the angle with the seat 2 in the initial state since the frame body 5 is inclined, Become.
[0026]
In this state, the angle between the seat portion 2 and the backrests 16 and 17 does not change. In this state, since the lower backrest 17 does not move the seat portion 2, the lower backrest 17 does not need to be displaced and does not need to be displaced.
[0027]
Next, an operation of moving the seat 2 forward and bringing it into a relaxation state, which is a tilt state in which the seat 2 is tilted, will be described with reference to FIGS. 5, 13 and 14.
To change to this state, the seat 2 described with reference to FIGS. 7 and 8 is advanced, and then the tilt operation of FIGS. 11 and 12 is performed, or the seat 2 is tilted. Since the operation can be performed by moving the seat 2 forward after performing the above, description of the entire operation is omitted.
[0028]
【The invention's effect】
As described above, the present invention has two modes, a tilt state in which the seat portion and the backrest tilt backward, and a slide state in which the seat portion advances in relation to the tilt state, or only the seat portion in addition to the two modes. Since it can be displaced independently from the mode of advancement, it can be adapted to various modes such as rear shampoo, massage, facial esthetic and relaxation when employed in a hairdressing salon.
[0029]
Further, the backrest is divided into a plurality of parts, the lower backrest is rotatable with respect to the upper backrest, and the lower surface side of the lower backrest is displaced toward the seat portion when the seat portion is advanced. The effect of not giving the impression that the seating comfort of the person who is seated, such as a patient, is deteriorated because the gap in the backrest is eliminated.
