Description

  The present invention relates to a side breath in which an arm is placed when a user sits down on a seat and relaxes.

When you sit down and sit down on a chair, you can relax and relax by staying flat on the side of your body without hanging your arms. A side breath has been used as a tool for that purpose.
The side breath must always be located at a certain distance from the side of the seat portion of the seat in terms of its usage. Otherwise, if the user sits on a seat and puts his arm on the side breath, the side breath will be pushed outward or forward and away from the body.

The means taken so far to solve this problem has been to place the side breath in association with the seat or its seat. Patent Document 1 shows an example thereof.
However, seats of various sizes and shapes are made so as to suit the size of the person's body. Therefore, various types of seats that match each of the various seats were selected for the side breath.

The two main techniques used in the past to arrange the side breath in association with the seat or the seat are the following two.
One of them is a combination of various side chairs with special side breaths that are combined together. The other is one in which a pair of side breaths are arranged on the left and right sides and the two are connected by a horizontal plate or the like, as can be seen in the above-mentioned document (in particular, see FIG. 2).

  However, in the former technique, a mechanism for integrally connecting the seat and the side breath becomes complicated, which increases the weight and increases the manufacturing cost. In the latter technique, since the side breath is not fixed to the seat portion of the seat, it cannot be prevented that the side breath moves in the front-rear direction during use. Further, in order to correspond to seats having different widths, it is necessary to be able to expand and contract the length of the horizontal plate, and if a mechanism capable of expanding and contracting is added, it becomes a factor that increases the manufacturing cost. Furthermore, when the user is a disabled person without one hand, a pair of side breaths is not necessary, and the other side breath that is not used becomes useless long.

  The technical problem of the present invention is to solve various problems of the prior art, and with a simple mechanism, there is no production cost, the side breath does not move in the front-rear direction during use, and the seats with different widths If the user is a handicapped person without one hand, it is sufficient to use only one side breath without buying two side breaths. The purpose is to be able to handle seats of seats with various thicknesses.

In order to solve the above technical problem, in the present invention, the side portion of the seat portion of the seat is sandwiched between the upper holding plate and the lower support plate from above and below.
In other words, the lower support plate is extended inwardly from the base of the side breath, the upper holding plate is disposed above the lower support plate, and the height position adjustment is performed by setting the base end of the upper holding plate upright on the base. Connected to the mechanism. Note that “connected” means that two members are connected or the connection is released.

In the present invention, the height of the upper holding plate can be freely changed by using a block that can move up and down along the support pillar.
That is, the height position adjusting mechanism is configured by a support column established on a base and a block that can move up and down along the support column, and the base end of the upper holding plate is connected to the block.

In the present invention, the side breath base and the height position adjusting mechanism can be manufactured separately.
That is, the height position adjusting mechanism is composed of a screw hole provided in the base, a screw rod screwed into the screw hole, a lower support nut and an upper holding wing nut screwed into the screw rod, The base end was provided with a through hole that was loosely fitted to the screw rod.

In addition, the present invention employs the following means so that the lower support plate can be easily separated from the base of the side breath.
A recess in which the base end portion of the lower support plate is fitted is formed in the bottom surface of the side breath base, and the base end portion is screwed to the base.

  In the present invention, the lower support plate is provided on the base of the side breath, and the upper holding plate connected to the height position adjusting mechanism is disposed above the lower support plate. If the height is adjusted by placing the side part and holding it with the upper holding plate from above, it is possible to firmly hold the seat with various widths and widths between the lower supporting plate. Therefore, the seat and the position of the side breath of the seat chair are fixed so that they do not move, and the side breath moves forward, backward, left and right with respect to the seat chair without connecting the left and right side breaths with a horizontal plate etc. Will not occur, and as a result, even if the sigh is only on one side, the function can be fully exerted. Moreover, since the whole structure is simple, it is lightweight and easy to carry.

  In the present invention, the height of the upper holding plate is composed of a support column established on the base and a block that can move up and down along the support column, so it can be moved and stopped along the column. Anything can be used as long as it is present, and it becomes possible to produce the inventive device using commercially available blocks.

  In the present invention, since the side breath base and the height position adjustment mechanism can be manufactured separately, a special process is to provide a screw hole in the base and a through hole at the base end of the upper restraining plate. For the screw rod screwed into the screw hole, the lower support nut screwed into the screw rod and the upper holding wing nut, all commercially available parts can be used as they are. Therefore, the proposed product can be manufactured very easily without labor and cost.

  In the present invention, since the lower support plate is screwed to the lower surface of the base of the side breath, the lower support plate is separated by unscrewing the screw as necessary, and the original shape of the original side breath is restored. Can be used by fixing.

1 is a perspective view of an embodiment of the present invention. It is sectional drawing which shows the related structure of the low-order support plate of this invention, a high-order holding plate, a height position adjustment mechanism, and the base of a side breath.

Embodiments of the present invention will be described with reference to the reference numerals in the accompanying drawings.
The height position adjusting mechanism 3 of the present invention only needs to be able to arbitrarily determine the height of the upper restraining plate 2. From the viewpoint of minimizing the manufacturing cost, it is desirable to select one that is simple and easy to handle.
For the lower support plate 1 and the upper holding plate 2, wood, plywood, synthetic resin plate, or the like is used. However, since the seat portion 11 of the seat chair is firmly sandwiched from above and below, the seat portion 11 must have such rigidity.

  Although not shown, the support column described in claim 2 tries to bend the load generated at the base end of the upper holding plate 2, that is, the support column, when the seat 11 of the seat is firmly held from above. The thickness is selected so as to have rigidity against the force (the same applies to the screw rod 6 described later). Further, although the block is not shown in the figure, it can be appropriately selected from known parts in which the height of the upper restraining plate 2 is arbitrarily determined.

A good example of the height position adjusting mechanism 3 of the present invention is shown in FIGS.
In the case of this example, first, the upper holding wing nut 9 is screwed into the screw rod 6, the upper holding plate 2 is attached to the screw rod 6 through the through hole 12, and the lower support nut 7 is attached from below. The screw rods 6 to which the screws are attached are screwed into the screw holes 5 of the side breath base 4.
In order to further secure the connection of the upper holding plate 2 to the screw rod 6, a rubber bush 8 is provided between the upper holding plate 2 and the nuts 7 and 9 as shown in FIG. Insert it.

  Next, as shown in FIG. 2, the seat portion 11 of the seat is inserted between the lower support plate 1 and the upper holding plate 2. Finally, the upper restraint wing nut 9 and the lower support nut 7 are twisted and lowered while finely adjusting the upper restraint plate 2, and the bottom 11 of the seat is firmly placed between the lower support plate 1 and the upper restraint plate 2. Pinch.

  As shown in FIGS. 1 and 2, the depth of the recess formed in the lower surface of the side breath base 4 is preferably the same as the thickness of the lower support plate 1. By doing so, the lower surface of the lower support plate 1 and the lower surface of the side breath base 4 are flush with each other and can be brought into close contact with a flat floor surface to stabilize the entire side breath. Note that, as shown in FIG. 2, the drilling position of the recess may be a position where the lower support plate fixing screw 10 can be screwed into the screw hole 5, or may be set to another position in consideration of balance or the like. Of course, it may be.

In the figure, a side breath base 4 is shown in which two plates are stacked, but in this way, the following two merits can be obtained.
For one, if the two plates are stacked, the thickness of the base 4 increases and the depth of the screw hole 5 can be increased, so that the screw rod 6 can be screwed deeply and fixed firmly. Second, compared to the case of using a thick single plate that can obtain the same depth, the double plate can be obtained at a lower cost and also looks better.

  In addition, although two adjustment holes 13 are drawn on the upper holding plate 2 in FIG. 1, this can be achieved by replacing the through holes 12 in which the screw rods 6 are loosely fitted with the holes 13. This is to enable the inward protruding length to be arbitrarily changed according to the width of the bottom 11 of the seat. It goes without saying that elongated slits may be provided instead of the plurality of adjustment holes 13.
