Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a supine health chair.

``Conventional technology'' A health chair has been developed in which the seat and backrest are tilted backwards to allow the user to lie down and rest his or her mind and body (Japanese Patent Application Laid-Open No.
61-103441). However, a manual drive is required to tilt and raise the backrest. This requires a driving device because the seated person's front and rear balance around the waist is poor, causing the person to lean backwards rapidly and have trouble standing up.

"Problems to be Solved by the Invention" The object of the present invention is to provide a simple and easy-to-use supine health chair that provides good front-to-back balance centering on the lumbar region when lying on the back, and therefore does not require a lifting device. It is something.

``Means for Solving the Problems'' The present invention pivots the middle of the elbow rest to the upper end of a pair of support frames provided on the machine frame so as to be tiltable, and the front part of the elbow rest and the support frame A connecting rod is swingably hung from the upper part, a seat is pivotably supported at the lower end of the connecting rod, a backrest is pivotally supported at the rear end of the arm rest, and the lower end of the backrest The above armrest is pivoted to the rear end of the above seat,
The present invention is constituted by a supine health chair, which forms an interlocking mechanism for the seat and backrest, and has stoppers at the upper end of the support frame for the horizontal and rearwardly tilted positions of the elbow rests.

``Function'' Therefore, the user can sit down on the seat 5, rest his back against the backrest 6, place his elbows on the arm rests 3, 3, and do his work while facing the desk 24. When taking a break, pull your hips behind the seat 5, grasp the elbow rests 3, 3 with both hands, and tilt your upper body backwards, and the elbow rests 3, 3, connecting rods 4, 4', seat 5, and backrest 6 will move together. The patient then leans back from the sitting position shown in FIG. 1 as shown in FIG. 3. That is, since the elbow rests 3, 3 tilt backward around the upper ends of the support frames 2, 2, and the backrest 6 falls backward, the seat 5, which is pivoted to the lower end of the backrest 6, is pushed forward and moved. The rods 4 and 4' swing forward to tilt the seat 5 backward, and the lower back is supported between the front end of the reclined backrest 6 at the rear of the rearward tilted seat 5, and in this state, the elbow rests 3, 3 is stopped by the backward tilt position stopper 8' and maintained in that state (supine state). After that, use both hands to hold the elbows 3, 3.
When you raise your upper body by grasping the
Since the elbow rests 3, 3 and the seat 5 return to their almost horizontal state and are stopped by the horizontal stopper 8, the user can work while facing the desk 24 with his or her upper body forward. As mentioned above, as the upper body leans back and stands up, the backrest 6 falls down and stands up, and the seat 5 moves towards the support frame 2.
The arm rests 3, 3 move back and forth around the upper end of the support frame 2, and the arm rests 3, 3 tilt back and forth around the upper end of the support frame 2 in conjunction with each other.

"Example" A caster 10 is provided at the tip of the spider leg 9,
An upright shaft 12 is provided on the boss portion 11 of the leg 9, and the machine frame 1 is formed on the upper part of the upright shaft 12 by supporting the center portion of a horizontal rod 13 so as to be freely rotatable in the horizontal direction. Upright support frames 2, 2 are provided at both ends of the horizontal rod, and the middle portions of the elbow rests 3, 3 are pivotably supported at the upper ends of the support frames 2, 2 by means of pins 14, and the support frames 2, 2 Backward tilt plate 1 on the top of
5 is welded and fixed, and a horizontal position stopper 8 for the elbow rests 3, 3 is provided on the upper surface of the front end of the rearward tilting plate 15, and a rearward tilting position stopper 8' is provided on the upper surface of the rear end. Above elbow rest 3,3
Connecting rods 4, 4' are swingably vertically attached to the front end and the rear inclined plate 15 by means of pins 16, and these connecting rods 4, 4'
A seat 5 is pivotally supported at the lower end of the seat 4' by a pin 17 so as to be freely tiltable. Further, the middle part of the backrest 6 is pivotally supported at the rear end of the elbow rests 3, 3 by a pin 18 so as to be able to rise and fall freely, and the lower end of the backrest 6 is pivotally connected to the rear end of the seat 5 by a pin 19. Possibly elbow rests 3, 3,
It forms an interlocking mechanism 7 for the seat 5 and the backrest 6. A pair of pipes 20, 20 are supported on the lower surface of the seat 5 in the front-rear direction, and telescopic rods 21, 21 are slidably fitted into the pipes 20, 20.
Connect the tips of 1 and 21 with the horizontal rod 22, and
Place your foot on the mat 23 and hang it down. In the figure, 3' is an arm rest mat, 5' is a mat for the seat 5, 6' is a mat for the backrest 6, and 24 is a desk.

"Effects" Since the present invention is configured as described above, by simply sitting down on the seat 5, grasping the armrests 3, 3 with both hands and tilting the upper body backward, the backrest 6 will fall backward and at the same time. Since the seat 5 is pushed forward and tilted backward, the lower back is supported between the rear part of the seat 5 and the front part of the backrest 6, that is, below the pivot part (pin 14) of the arm rests 3, 3, 3 can also support both elbows by tilting backwards around the same pin 14, and this state is stopped by the backward tilting stopper 8', so the patient can safely and comfortably shift to a supine position by simply tilting the upper body backwards. In addition, simply by grasping the elbow rests 3, 3 with both hands and raising the upper body, the backrest 6 will rise to its original position, and at the same time, the elbow rests 3, 3 and the seat 5 will return to their original positions, and the state will be horizontal. Supported by the position stopper 8, it is stable and has the effect of easily returning to the office work position.
