DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat and chair used in a house, particularly at an entrance.

[0002]

2. Description of the Related Art In Japan, the population structure is rapidly aging, and with this, barrier-free houses without steps have been recently developed. However, at the entrance, there are problems such as intrusion of rainwater and the like, and it is difficult to eliminate a step. Therefore, it is troublesome and painful for the elderly to put on or take off shoes at the entrance when going out or going home.

[0003] In some cases, a sitting chair or stool is provided at the entrance so that the elderly can sit and change their shoes. In order to provide a seating chair at the entrance, the entrance must be wide enough, but in view of the housing situation in Japan, it is often difficult to secure enough space as described above. .

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems by installing a foldable seat chair described below at the entrance.

[0005]

The present invention will be described with reference to the drawings. FIG. 1 is a perspective explanatory view of a foldable seat chair according to the present invention. FIG. 3 is an explanatory view of the external appearance of a state in which it is folded and stored. 2 and 4 are cross-sectional explanatory diagrams. However, FIG. 2 does not show the mat for covering the surface of the seat plate and the pulling metal fittings of the double door, and FIG.
The mat is not shown. In the figure, F is a frame member that covers the left and right side surfaces and the upper surface of the inner surface of the opening provided on the wall surface. On the lower surface of the inner surface of the opening, the floor material Y may be extended, or another plate material may be laid. When the opening is provided between the entrances, the floor material Y is usually a tile or a concrete mortar.

The inner surface of the opening is closed by an outer wall or a wall material of an adjacent room. If the back surface of the wall material is not visible from the opening and is not visually appealing in design, it is covered with an interior material such as a plywood or a decorative board. do it.

A door D has a double-opening structure in which two right and left doors open toward the user. A is a seat plate of the chair of the present invention. The seat plate A is attached to the shelf plate E by a hinge K, and rotates forward with the hinge K as a rotation axis. 1 and 2 show a state in which the seat plate A can be used as a chair, while FIGS. 3 and 4 show a state in which the seat plate is stored in a wall.

When the seat plate A is used as a seat chair from the state shown in FIG. 3 or FIG. 4, first, the two double doors D are opened to the front side by 90 degrees and fixed at that position. Next, the seat plate A is rotated forward by 90 degrees to the front side, and the left and right sides thereof are supported by the upper side surface of the door D. When the chair is folded and stored in the wall from the state shown in FIG. 1 or FIG. 2, the above procedure may be reversed. That is, the seat plate A is rotated 90 degrees upward and closed. Subsequently, the left and right doors D are closed. The door D is attached to the frame member F via a hinge having a maximum opening angle of 90 degrees so as to open from a closed state to a maximum of 90 degrees.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention mainly comprises athletic ability,
It is intended for the elderly or disabled, whose attention is lower than that of ordinary people, so it is desirable to consider the following points in implementation.

First, from the viewpoint of safety, the seat plate A, the door D, the shelf plate E, the hinge K, and the like must be sufficiently strong. Since the seat plate A needs to be fixed horizontally when it is used, the hinge K is suitably a slide hinge. In combination with the slide hinge, the left and right frame members F and the seat plate A may be connected by a crossing bracket to assist the rotation of the seat plate A. In particular, the plow with a brake can gently rotate the seat plate A forward, so that it is safer and easier to handle.

A reinforcing material U is provided on the back surface of the shelf E,
It is desirable to reinforce the shelf E over its entire length or to support the center of the span with a support from below.

In the structure for supporting the seat plate A by the door D, the hinge of the door D should be one that can be opened only up to 90 degrees at the maximum so that the seat plate A is shifted laterally and does not come off from the support of the door D. desirable. The opening angle of the door D is a predetermined angle, for example, 3
Beyond 0 degrees, the hinge springs open all at once to 90 degrees, and if a hinge with a spring fixed at that position is used, handling becomes easy.

As shown in FIGS. 3 and 4, a knob pull Q is attached to the upper corner of the seat plate A, and a hole into which the knob pull Q of the seat plate A fits is provided on the upper surface of the door D. H, and the hole H
Alternatively, the handle Q may be fitted to prevent the lateral displacement of the seat plate A.

In FIG. 1 and FIG. 3, the puller handle P or the knob puller Q is attached to the door D and the seat plate A, respectively, but the knob puller Q of the seat plate A is pulled as described above. This is to prevent the seat plate A from coming off the support of the door D in addition to the original purpose of the hand.

Therefore, if another prevention means is adopted, the knob puller Q is not always necessary. As will be described later, when an open catch is employed as a means for fixing the seat plate A in a closed state, the original function cannot be exhibited even if the knob puller Q is attached.

The puller fitting P of the door D is attached so as to cover the lower part of the seat plate A from the front side of the door D when the seat plate is stored. Apart from the original purpose of the puller, door D
If the seat plate A is not opened, the seat plate A cannot be rotated forward. In other words, it is dangerous to use the seat plate A as a seating chair without opening the door D by erroneous use. Therefore, the seat plate A is attached to cover the lower portion of the door D in consideration of safety. . Therefore, if another mechanism is employed such that the seat plate A cannot be tilted forward and forward unless the door D is opened, the pull fitting P does not need to cover the lower portion of the seat plate A. If another means such as an open catch is used for opening and closing D as described later, the pull fitting itself is not required.

The catch fitting with the door D closed is preferably an open catch. Lightly press door D to open,
When the door is closed, it can be closed by lightly pressing the door D, which is easy for the handicapped and elderly. Similarly, the catch of the seat plate A may be an open catch, but as soon as the catch is released, the seat plate A falls forward by its own weight, which may be dangerous for the handicapped or elderly. . Therefore, as described above, it is desirable to use the hinge K and the lashing fitting with the brake together to rotate the seat plate A.

When the door D is opened, if the door D comes into direct contact with the floor surface, the floor surface will be damaged. Therefore, a roller R is attached to the lower part of the door D to prevent the door D from damaging the floor surface. At the same time, the door D may be smoothly opened and closed.

In order to make the seat plate A easy to sit down, it is desirable to cover the seat plate A with a mat in which a cushion material such as urethane foam is placed, like the seat surface of an ordinary seat chair. In this case, on the seating surface near both sides of the seat plate, a material that is slightly higher than the height of the puller fitting P of the door D and that does not become dented even when human weight is applied, such as wood, is provided. Is desirable. By doing so, the puller fitting P of the door D does not interfere when the user sits on the seat. As shown in FIG. 1, when the seating surface is thickened, the space above the shelf board cannot be used for storage, but this space originally has a small depth and poor storage capacity.

Since the chair according to the present invention is installed so that it can be stored on the wall, the depth of the shelf plate E is almost equal to the wall thickness, and is about 10 cm in a normal house. The state when the door D is housed in the wall is shown in FIG. 3, and the door D is not particularly uncomfortable even when installed at the entrance. In addition, this appearance has various appearances depending on the shape of the puller fitting P and the knob puller Q.

Since the folding chair of the present invention is particularly convenient to be installed at the entrance of the entrance, it may be used in such a manner as to be straddled between the dirt of the entrance and the floor of the entrance as shown in FIG. Is considered to be the most frequently used form. That is, since the rotation range of one door of the double door D is on the entrance floor and the rotation range of the other door is on the front entrance, the double door is not symmetrical. 1
4 to FIG. 4, there is no difference in the method of using and storing the chair from those in FIGS. 1 to 4.

[0022]

The chair according to the present invention can be stored in a wall when not in use, so that it can be installed in a narrow entrance.
Further, since the maximum opening angle of the hinge for rotating the door D is set to 90 degrees, there is no danger that the seat plate A comes off from the supporting material of the door D, and the safety is ensured.

According to the second aspect of the present invention, since the forward tilting rotation of the seat plate A is assisted by the lashing fitting with the brake, the seat plate A tilts gently forward and is excellent in safety. According to the invention of claim 3, when the hinge of the door D opens at a predetermined angle or more,
Because it is a hinge with spring that opens to 90 degrees at a stretch, door D
When the is opened to a predetermined position, for example, 30 degrees, it is immediately opened at 90 degrees and fixed at that position, so that it is not necessary to adjust the opening angle of the hinge, and it is easy to handle for the elderly and the disabled. is there. The invention of claim 5 is an invention in which the seat plate A is securely fixed to the door D so that the seat plate A does not come off from the support of the door D. The invention according to claim 6 takes safety into consideration so that the seat plate A cannot be used as a seat chair unless the door D supporting the seat plate A is opened. The invention of claim 7 applies the present invention to the most convenient position when an elderly person or a disabled person changes shoes.
