It is.

According to a second aspect of the present invention, there is provided a chair comprising: a seat;
It is composed of a leg for supporting the seat, and a backrest and handrail provided on two sides perpendicular to the outer periphery of the seat in an L-shape in plan view.

[0010] The chair according to the third aspect of the present invention provides the chair according to the first aspect.
Or the chair of the present invention described in 2 above, wherein the backrest and the handrail has a size having a leg function.

According to a fourth aspect of the present invention, there is provided a chair comprising: a seat;

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram relating to an example of a chair according to the present invention. The illustrated chair 1 includes a seat 2, legs 3 supporting the seat 2, and a backrest and handrail 4 provided on the seat 2. , And 5.

The seat portion 2 is covered with a cover 6 made of cloth, synthetic leather, resin sheet material or the like with a cushion material inside. The seat 2 in this example is made of urethane vinyl leather. Further, this seat portion 2 has two sides 7 and 8 of the outer periphery orthogonal to each other,
It is a substantially square in plan view in which the front corner 9 is formed in an arc shape. Needless to say, the seat portion 2 can be freely designed so that the two sides 7 and 8 of the outer periphery intersect at right angles as shown in the figure, or can be changed to a shape that intersects at an obtuse angle or an acute angle. In this case, the backrest and handrails 4, 5 described later are provided at a right angle, an obtuse angle, or an acute angle with respect to the seat 2. In the present invention, the above-mentioned predetermined angle on two sides intersecting at a predetermined angle on the outer periphery of the seat 2 is a right angle as in this example, an appropriate acute angle or an appropriate obtuse angle.

The leg 3 is a columnar member made of wood, metal, hard resin, or the like. The leg 3 is provided at the bottom of the seat 2 near the front corner 9 to support the seat 2 at an appropriate height.

In this example, the backrest rails 4 and 5 each have a leg function and are formed in such a size that the lower ends 11 and 12 abut on the ground plane 10 similarly to the leg 3 described above. In the illustrated example, the two sides 7 and 8 of the outer periphery of the seat 2 are
Are perpendicular to each other, backrests and handrails 4 and 5 are provided on the seat 2 in an L-shape in plan view. Of course, if the legs (not shown) are shaped so that they do not fall down when sitting on the seat 2 and leaning on the backrests and handrails 4 and 5, the backrest and handrails 4 and 5 can function as leg portions. , That is, a size in which the lower ends 11, 12 do not abut against the ground plane 10.
It may be of a shape.

Each of the backrests and handrails 4 and 5 has a rectangular shape and has a plurality of vertical bars 11 and an open portion 12 at an upper portion. Also, the handrail unit 13 is configured such that a part 13a is
3b to make it easier to hold.

The above-mentioned chair 1 is effective when used mainly for beds for the handicapped, sick, elderly, etc., chaise lounges, porches and the like. That is, as shown in FIGS. 2 and 3, for example, near the bed 14, one end 4
The chair 1 is placed so that a contacts. Then, feet are put on the floor so as to descend from the bed 14, for example, the right hand is the backrest and the handrail portion 13 of the handrail 5 and the left hand is the backrest and the handrail portion 13 of the handrail 4. Next, the left hand is moved toward the handrail portion 13 of the backrest / handrail 5. As a result, the body is naturally turned over, and it is possible to safely sit down by sitting down on the seat 2 in the state as it is. When grasping the handrail portion 13, particularly in the case of the above example, the thin portion 1 of the backrest / handrail 5 with the right hand is used.
By grasping 3a (see FIG. 1), the backrest and handrail 5 can be grasped more strongly, and the body can be reliably supported.

Further, as another method of sitting on the waist (see FIG. 3),
A disabled person or the like who has risen from the bed 14 can be safely and easily moved to the seat 2 by sliding his / her lower back and holding the backrest / handrail 4 with the left hand to further move the body to the seat 2. Chair 1 next to 14
You can sit down.

The chair of the present invention is not limited to the above example,
What does not have the leg part 3 may be sufficient. In this case, the backrest dual-purpose handrail supports the seat 2 as a leg. Therefore, the backrest and handrail must have a shape and structure that will not cause the balance to fall and fall down even when the user sits down on the seat 2.

Further, the shapes of the seat 2, the leg 3, the backrest and the handrails 4, 5 are not limited to the illustrated shapes.
The design can be freely changed to another shape.

Further, the chair of the present invention may have a structure in which the height of the seat 2 can be adjusted. In this case (see FIG. 4), as an example, the leg 3a is divided into two,
Is provided with a bolt 16 protruding from the upper end. At the lower end of the other leg 17 fixed to the bottom of the seat 2 (see FIG. 1), a bolt hole 18 into which the bolt 16 can be screwed is provided. Then, the bolt 16 of the leg portion 15 is screwed into the bolt hole 18 of the leg portion 17 and the leg portion 15 is turned clockwise or counterclockwise to shorten or lengthen the entire length of the leg portion 3a. 2 can be adjusted to any height. The seat 2 (see FIG. 1) is provided with a plurality of holes (shown by phantom lines in FIG. 1) at predetermined intervals in the vertical direction of the backrests and handrails 4, 5 to adjust the expansion and contraction of the leg 3a. At the same time, the mounting height position of the seat 2 with respect to the backrest / handrails 4 and 5 is changed, and a screw or a bolt is passed through the hole at a desired height position.
And the seat 2 can be fixed at a desired height position.

[0025]

As is apparent from the above description, the chair of the present invention is provided with a backrest and a handrail on two sides intersecting the outer periphery of the seat at a predetermined angle, so that a disabled person, an elderly person, a sick person, etc. When the user gets up from a bed or the like and sits in this chair nearby, the handrail portion of the backrest and handrail can be safely turned over with the movement of the body, and the user can easily sit down. Therefore, the help of an attendant is not required, and the burden on the attendant such as a family can be reduced.

Further, by providing a backrest and a handrail in an L-shape in plan view on two orthogonal sides of the outer periphery of the seat portion, a handicapped person, an elderly person, a sick person, and the like can use the handrail when sitting on a nearby chair after getting up from a bed or the like. With the backrest and handrail that is open each time, it is easier to grasp, and it is possible to turn the body more safely and sit down on the seat.
