DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height-adjustable table adapted to eliminate a difference between a table and a chair, which is caused by a difference in physique between a wheelchair and a dining room. Things.

[0002]

2. Description of the Related Art Currently, in a nursing home for the elderly with many wheelchairs, when eating at a table in a cafeteria, the height of the tabletop at the table may be too high for some users, or the wheelchairs and armrests of the wheelchair may be too high. It is often found that it is difficult to bring the body close to the top plate. For this purpose, a table having a top plate having a different height according to the user's physique has been prepared to cope with the problem.

[0003]

However, it is not enough, however, to provide a table with different standard dimensions, which requires equipment costs, and is not enough to cope with the problem. There are also problems that require human resources. The present invention has been proposed in order to improve such a problem, and eliminates the difference between the table and the chair, which is caused by the difference in the physique between the wheelchair and the dining room, and between the user and the chair. It is an object of the present invention to provide a height-adjustable table as described above.

[0004]

In order to solve the above-mentioned problems, the present invention provides a table having a pair of legs,
A vertical and horizontal frame is interposed between these legs, and a top plate support is provided on the legs and frame to support the top plate at different heights. It has a plurality of receiving grooves adapted to be supported at different heights, and the top plate is for a wheelchair user having a gore for a wheelchair armrest formed on both sides, and for a normal user. Have , and select the top plate according to the user,
It was configured to be mounted so as to be supported at the corresponding height .

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a height-adjustable table according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a height-adjustable table 1. The height-adjustable table 1 has a leg 2 on which a top plate (described later) is adjustable by a supporting height adjusting means (described later). It is. That is, the height-adjustable table 1 includes a pair of legs 2, 2 and a vertical and horizontal frame (described later) connecting these legs 2, a top plate receiver 3a for supporting the top plate at different heights, 3b, 3c, 3d, 3e
The top plate receivers 3a to 3e are provided with 20 to receive three sides of the top plate and support the top plate at different heights.
It has a plurality of receiving grooves 4 formed at intervals of 30 mm (see FIG. 2). The top plate includes a wheelchair top plate 5 for a wheelchair and a normal top plate 6 when a normal chair is used.
In order to prevent the armrest 8 of the wheelchair 7 from interfering with the wheelchair top 5 when the wheelchair 7 is brought close to the wheelchair top 5, both sides of the front surface of the wheelchair top 5 are provided. An undercut 9 is formed.

Next, the height-adjustable table 1 having such a configuration will be described in more detail with reference to FIG.
First, the leg 2 includes a pair of columns 2a, 2a and a cross beam 2b.
And a lower beam 2c connecting the lower ends of the pair of columns 2a, 2a. In addition, these pair of legs 2
It is structured to be connected by vertical and horizontal frames 10. This frame 10 has a long frame 10a along the table longitudinal axis direction, a short frame 10b having a cross section at both ends of the long frame 10a, and a cross section having a cross section orthogonal to a middle portion of the long frame 10a. It is constituted by the short frame 10c. The two short frames 10b are connected to the legs 2
The length of the short frame 10b is substantially equal to the dimension of the lower surface side of the horizontal beam portion 2b in FIG.
And fixed by a fastening member (not shown) or the like. A plurality of receiving grooves 4 are formed on both sides of the top plate receivers 3a to 3e to support the wheelchair top plate 5 or the normal top plate 6 at different heights in the longitudinal direction. Of these, the top plate receivers 3a and 3e are respectively
And the top plate receiver 3c is fitted and mounted on the short frame 10c having a U-shaped cross section orthogonal to the middle of the long frame 10a so as to straddle the long frame 10a. . Further, the top plate receivers 3b, 3
d is designed to be mounted along the long frame 10a. When the top plate receivers 3a to 3e are mounted, the plurality of receiving grooves 4 formed respectively are at the same height for each of the receiving grooves 4. Note that the top plate receivers 3a and 3e on the upper surface of the cross beam portion 2b of the leg portion 2 may be formed integrally with the leg portion 2.

Next, on the wheelchair top plate 5 and the normal top plate 6, when mounted on the top plate receivers 3a to 3e, the front surface facing the user projects from the leg portion 2 and the short frame 10c. The dimensions are set as follows.
The width is set so as to match the width of the wheelchair 7.

As described above, according to the height-adjustable table 1 according to the present invention, it is possible to select the wheelchair top plate 5 or the normal top plate 6 depending on the physique of the user or whether the user uses a wheelchair or a normal chair. By adjusting the supporting height, it is possible to cope with the problem. Therefore, it is easy to use, there is no need to prepare a table having a special dimensional standard, and the equipment cost can be reduced.

For example, as shown in FIG. 4, for a user who uses the wheelchair 7, the wheelchair
a to 3e. At this time, in order to adjust the height of the wheelchair top plate 5 according to the physique of the user of the wheelchair 7, the wheelchair top plate 5 is inserted into the receiving groove 4 in the top plate receivers 3a to 3e having a suitable height. I do. Thereby, even if the user of the wheelchair 7 advances the wheelchair 7, the armrest 8 does not interfere with each other by entering the hole 9 so that the abdomen of the user comes close to the front of the wheelchair top 5. Can be done.

On the other hand, in the case of a normal chair user, the normal top plate 6 is inserted into the top plate receivers 3a to 3e. Also at this time, in order to adjust the height of the normal top plate 6 according to the physique of the user, the normal top plate 6 is inserted into the receiving groove 4 of the top plate receivers 3a to 3e having a suitable height (FIG. 5).

Further, the configuration shown in FIG. 6 can be used for any user regardless of whether the user uses the wheelchair 7 or a normal chair. That is, the wheelchair top plate 5 or the normal top plate 6 corresponding to each is inserted. Also at this time, it is inserted into the receiving groove 4 in the top plate receivers 3a to 3e having a height suitable for the user's physique.

[0012]

According to the present invention, it is possible to cope with this problem by selecting the top plate or adjusting the supporting height according to the user's physique, or whether the user uses a wheelchair or a normal chair. It is easy to use, there is no need to prepare a table having a special dimensional standard, and equipment costs can be reduced.
