Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair-type pine-surgery machine, and particularly to a chair-type pine-surgery machine having a backrest portion that is comfortable to lean on and has a simple structure.

The backrest of a conventional chair-type pine surge machine has a cushion body attached to the backrest frame, and a bag-shaped exterior sheet is attached to it and fastened with hooks or fasteners. Since it is not shaped to follow the curve of the back, it is uncomfortable to lean on and does not look good.

Another conventional 7-chair pine surge machine has a separate backrest, and some are individually attached to the backrest frame so that the shape follows the curve of the back of the human body. There is a problem that the installation work becomes troublesome and expensive. Furthermore, there is also the problem that the outer sheet placed over the cushion does not cover the cushion body closely, causing the central portion to sag.

The present invention was developed in view of the above-mentioned problems of the prior art, and its purpose is to provide a chair-type pine surgery machine with a simple structure and a backrest shaped to conform to the back force of the human body. It is about providing.

To achieve this purpose, the chair-type pine surge machine of the present invention has a box-shaped backrest frame attached to the backrest frame whose front side, that is, the side on which a person leans, is shaped to follow the curve of the back of the human body. The front frame has an elongated cut-out window on the front surface of the front frame to actuate the massaging balls that are built into the back frame, and the front H A plurality of protrusions protruding toward the back side of the front surface of the human body are provided at predetermined intervals. A bag-shaped exterior sheet having a curved surface has a window cut out at a position and shape that matches the cutout window of the front frame, and this window is flanked by another exterior sheet,
A flange portion is provided along the entire circumference inside the seam of these exterior sheets, and a flange portion is provided on the flange portion at the same interval as the protrusion of the front rest frame, for hooking onto the protrusion. A plurality of are attached, the exterior sheet is placed over the front sr2*rest frame body, the mounting tool is hooked on the front 6 body protrusion, and the exterior sheet has a backrest portion which is fixed to the backrest frame body. This is expressed as a percentage.

The chair-type pine surge machine of the present invention will be explained in detail below based on the drawings. FIG. 1 is a perspective view of an embodiment of the chair-type pine surge machine of the present invention.

In this figure, 1 is a seat part, 2 is an armrest part, 3 is a backrest part, 4 is an armrest for reclining the backrest part 3, that is, changing the tilt angle to the rear, and 5 is a part for each of the above parts. This is the seat frame on which it is placed. Numeral 6 and 6' are massage balls for massaging the back muscles of the human body, and the massage balls 6 and 6' are built into the backrest portion 3 together with mechanical parts such as an electric motor and a screw shaft for operating them. The above are the parts that generally make up a chair-type pine surge machine. Next, the configuration of the backrest portion 3, which is directly related to the present invention, will be explained. 12 is a backrest frame, 11 is a main part constituting the backrest part 3, which is a box-shaped backrest frame that is attached to the backrest frame 12 with screws or nuts, and 8 is the front side of the backrest frame 11, that is, the side on which a person leans back. 7 is a backrest frame 11 which constitutes a surface and has a curved surface shaped along the back curve of the human body;
In the center of the front side, there is an elongated cut-out window formed in order to allow the massaging balls 6.6' to act on the back muscles of the human body, 9 is a headrest part on which the head is placed, and 10 is a receptacle in which the end of the seat part 1 is housed. The back support part 8, the headrest part 9, and the waist part 10 integrally constitute a box-shaped backrest frame 11. Cushion bodies 13 and 13' each having a uniform thickness are attached to the surfaces of the back support part 8 and the head rest part 9, and serve as cushioning bodies for the back and head. Reference numeral 14 denotes an exterior sheet made to have substantially the same shape as the backrest frame 11 and to be placed over the backrest frame 11. This Gaitetsu notebook has a curved surface 15 on the front that is almost the same as the back support 8.
At the top of this front surface, there is a bag-shaped exterior sheet 17 in which a window is cut out in a position and shape that matches the recess for the nose rest 9 and the cutout window 7, and this window is inserted into the exterior sheet 18.
It is made by sewing with. 19 is the exterior sea) 17
．． 18 This is a bead that is interposed at the seam to improve the appearance of the seam. FIG. 2 is a perspective view of the backrest frame 11 of the chair-type pine surge machine shown in FIG. 1, as seen from the back side. In this figure, reference numeral 24 indicates a protrusion provided over the entire inner circumference of the frame of the cutout window 7, 23 indicates the second part of the 7 run, and the protrusion 24 protrudes toward the back side of the front surface of the backrest frame 11. ing.

FIG. 3 is a perspective view of the exterior sheet 14 of the chair-type pine sage shown in FIG. 1, as seen from the rear, and FIG. FIG. 3 is a sectional view of main parts in a combined state.

In FIGS. 3 and 4, 20 indicates the exterior sheets 17 and 18.
The flange portion 20 is provided over the entire inner circumference of the seam, and the flange portion 20 is sewn with a bead 19 interposed therebetween. Reference numeral 21 denotes a plurality of fittings, for example, fittings, which are attached to the flange 820 at the same intervals as the projections 24 (FIG. 82) of the backrest frame 11. 22 is the exterior sheet 17
A stop provided at the rear of the holder, for example 7 asuna.

In each component configured as above, the cushion body 13
．． 13' is attached to the backrest frame 11, the exterior seam)
14 is covered, and the mounting bracket 21 attached to the front layer side of the exterior/-) 14 is attached to the protrusion 2 provided on the backrest frame 11.
It is fixed by hooking it on each of 4 and fastening 2.
2 is closed and the extranuclear g/-) 14 is fixed. Therefore, the W-weeping portion 3 of the girder-type pine serge machine of the present invention is configured such that all of the medium heat fnk of the exterior seam 14 is fixed to the backrest frame 11 by the clamping fittings 21. Exterior sheet 14 without sagging fire part
can be fitted into the cushion body 13.13'.

As described above, in the chair-type pine surge machine of the present invention, the backrest portion is formed in a shape that follows the back of the human body, so that the comfort of leaning back can be improved and the appearance can be improved. In addition, since the structure of this backrest portion is very simple, it is possible to improve the assembly workability, and it can be manufactured at a much lower cost than ever before. Furthermore, without sagging the exterior sheet, 2773
It can be brought into close contact with 7 bodies. As described above, the effects of the present invention are remarkable.
