[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table set having a table and a chair, wherein the chair is fixed at a relative position with respect to the table.

[0002]

2. Description of the Related Art Conventionally, as a table set of this type, a chair is fixed in a posture with respect to a desk so that a normal person can easily and stably take a seat. It has been known. Such a table set is convenient for positioning a chair as a table dedicated to a person, and is used, for example, in a park facility or the like, for the purpose of enabling a large number of people to use the table fairly and comfortably.

[0003]

However, the above-mentioned table set is configured for use by a healthy person. However, once a wheelchair user uses the table set, the seating space of the table is limited by the chair. I was not able to use my wheelchair as a chair and sit down. Therefore, considering that the above-mentioned table set is used by a wheelchair user, the wheelchair user must go down the wheelchair and move to the chair. For this reason, a heavy burden is imposed on the wheelchair user, or the work of the caregiver is increased, which is not preferable in terms of the burden on the user. The seat plate simply occupies an obstructive space, such as the necessity of providing a separate table.

Accordingly, it is an object of the present invention to make it possible to use a wheelchair as it is as a chair for sitting on the chair, and to easily use the chair itself of a table set.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a feature of the present invention for achieving the above object is to provide a table 1 and a chair 2, and to move the chair 2 relative to the table 1. In the table set fixed in position, the seat plate portion 22 of the chair 2 is placed on a seating space S for a person to sit on a table.
And a second position that is located beside the seating space S and allows the wheelchair C to enter the seating space S, and is configured to be switchable between the first position and the second position.
A first fixing state for fixing the position of the plate portion 22, and the first posture
In the unlocked state where the position can be switched from
The operation section 3 for switching operation is operated from above the seat plate section 22.
A chair leg 21 fixed to the desk 1 in a relative position with respect to the desk 1 is provided beside the sitting space S so that the seat plate 22 can be freely operated. The operation unit 3 is swingably provided around the chair leg 21 , and the
The second fixed state in which the position of the seat plate portion 22 is fixed in two positions.
Fixed position switchable from the second position to the first position.
The position switching operation may be freely performed in the fixed release state .

Although the drawings have been referred to to describe the characteristic configuration, the drawings are used merely for reference and the present invention is not limited to the drawings.

[Effects] In other words, when the seat plate portion of the chair is in the first position located in the seating space, a healthy person can easily and stably take a seat similarly to a conventional table set. Further, when the seat plate portion of the chair is in the second position located beside the sitting space,
Since the seating space is in an open state to allow the wheelchair to enter, the wheelchair user can sit on the desk without getting off the wheelchair. At this time, the wheelchair user can be seated in the same seating space as the seating space of a healthy person, so, for example, when a plurality of seating spaces are provided adjacent to the table, Less likely to have adverse effects. As a result, the seat plate portion is formed such that the two positions can be freely switched, so that the seat plate portion can be properly used according to the needs of the seated person, and a large number of people can enjoy the play fairly and comfortably. It was possible to provide a table set suitable for use in a highly public use that can be used. Then, the seat plate is positioned in the first posture.
The first fixed state to be fixed and the second posture from the first posture.
Switch the position to the fixed release state where the position can be switched to the posture
If the operation unit is provided and configured, do not maintain the functions described above.
Also, stabilize the posture of the seat plate portion in the first posture.
When a healthy person uses it, the seat plate becomes unstable and
It is possible to prevent a situation in which the user feels uncomfortable.

[0008] Here, a chair leg fixed relative to the desk is provided beside the seating space, the seat plate is swingably provided around the chair leg, and the operating part is provided. ,Previous
The second fixed state in which the position of the seat plate is fixed in the second posture.
Fixed position switchable from the second position to the first position.
If it is configured to be able to switch the position to the fixed release state,
In the second position, the seat plate is disposed beside the seat space.
Seated in the seating space,
Can be used as a carrier for placing luggage. this
Normally, the wheelchair user moves with his luggage on his lap.
The luggage tends to get in the way when you move and sit down
Because it is easy for the inconvenience to occur on the bed where the luggage is placed
This is also intended to be convenient for wheelchair users to sit down.
Is preferred.

In the present invention, the desk may be used indoors or outdoors, and does not depend on the presence or absence of drawers and other functions. Also, to sit down,
Refers to a person sitting at a predetermined position relative to the desk in a sitting position toward the desk, and the space including the predetermined position is called a sitting space, and the side of the sitting space is a state in which a person is sitting on the sitting space. Assuming that the person is facing the table, it points to the side. Further, in the present invention, the term “relative position fixing” refers to a state in which the position is fixed so that the position cannot be changed independently of each other, and it does not matter whether the posture can be changed.

1) and the legs of the chair 2 (chair legs 21) are both fixed to the cement-paved ground G.

The table is constituted by supporting a substantially square top plate portion 12 with a table leg portion 11, and forms a seating space S at four places facing four sides of the top plate portion 12. Chair 2 is provided. In addition, a C-shaped recess 13 is provided at each of the four corners of the top plate portion 12 to form an umbrella stand so as to be usable as a hook for the bag B (see FIG. 7).

The chair 2 has a single chair leg 2
A first posture in which a seat plate portion 22 is provided so as to be swingable around the chair leg portion 21 with respect to the chair 1 and the seat plate portion 22 of the chair 2 is located in a sitting space S for a person to sit on a table. When,
It is located beside the sitting space S, and is formed so as to be freely switchable to a second posture that allows the wheelchair C to enter the sitting space S. Further, an operation unit 3 is provided for switching the position of the seat plate 22 between the first fixed state in which the seat plate 22 is not swingable with respect to the chair leg 21 and the swingable fixed release state in the first posture. .

As shown in FIGS.
The rotary shaft 21d is fixed to a cylindrical support frame 21a fixed to the ground via a bearing 21b so as to be rotatable around the axis. The seat plate 22 is fixed to the rotary shaft 21d. The chair 2 can be formed. The support frame 21a
A circular flange 31 is provided at the upper end of the pair of upper and lower holes, and the flange 31 has a pair of upper and lower through holes 31 in the 0 o'clock direction and the 3 o'clock direction in plan view with the table 1 side up.
a and 31b, and a fan-shaped notch 31d from 6:00 to 9:00 (see FIG. 4).
The seat plate portion 22 is provided on the seat plate member 22a with the rotation shaft 21d.
And a pair of flange-shaped projections 33, 34 at the lower end of the attachment 22b.
And a through hole 33a is provided in one of the protrusions 33, and the seat plate member 22a is connected to the rotating shaft 21d.
