DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device which can open and close a single large door panel by sliding.

[0002]

2. Description of the Related Art A door attached to a frontage can be opened and closed via a hinge provided at one end of the door. However, if the door becomes large, not only the opening and closing force but also the turning radius of the tip of the door are increased. The opening / closing operation is not easy due to the large size. In particular, it is inconvenient for a person who cannot move his / her body freely in a wheelchair to operate a large opening / closing door.

By the way, as a device to be attached to a large wide frontage, a folding door is constructed by connecting two or three panels to form a folding door, and by folding these panels, the frontage can be opened. It has been known. FIG. 3 shows a conventional general folding door, but has two panels.
(A) and (b) are connected by a joint (c) so that they can bend, and a hanging frame (d) is connected to the hanging side, and a pull frame (e) is connected to one door side. ing.

[0004] In the figure, (a) shows the front door closed with the folding door stretched, and (b) shows two panels (a) and (b).
Is bent to partially open the frontage, and a folding door indicated by a dotted line represents a case where it is completely folded.
In this type of folding door, the hanging frame (d) is attached to the hanging side, and the pull frame (e) can be moved by being guided by the rail, and the pull frame (e) slides. The two panels (a) and (b) are folded and stretched.

In order to open and close the folding door, the pull frame is slid. However, when the folding door is completely closed as shown in FIG. Can not be pushed to, so once the panel (a),
When the vicinity of the joint (c) of (b) is pressed to make the half-open state as shown in (b), the pull frame (e) can be slid and folded. Conversely, when the folding door is extended, when the pulling frame (e) is pulled to a half-open state as shown in (b), the vicinity of the joint (c) of the panels (a) and (b) is pressed. It must be closed. By using such a folding door, even if the width of the frontage becomes even larger, it can be dealt with by increasing the number of panels, but the opening and closing operation is not easy, especially the opening and closing operation in a wheelchair is not easy. . In addition, a guide rail must be laid on the floor surface so that the lower end of the panel is guided. However, the floor surface may be obstructed by grooves.

[0006]

There is a problem as described above in mounting a large door or folding door on the frontage as described above. The problem to be solved by the present invention is this problem. To provide a sliding-type opening / closing door device that can smoothly open and close using a single large door.

[0007]

The sliding door device of the present invention is constructed so that one large door panel can be attached to the frontage and can be opened and closed. Then, when opening the frontage, the user slides while rotating, and moves almost vertically to one side of the frontage. An upper rail is attached to the upper part of the frontage, and a slider provided at the upper end of the door panel is restrained to move along the upper rail. This slider functions as a guide for opening and closing the door panel, and does not support the door panel.

A U-shaped frame having a vertical member and upper and lower arms is rotatably mounted on one side of the frontage, and the ends of the upper and lower arms are rotatably connected to the upper and lower end surfaces of the door panel via shafts. Supported by arm or lower arm. Here, the door panel rotates around the slider together with the turning of the frame, and can further move to the longitudinal member side of the frame to open the frontage. Therefore, the distance between the slider and the arm tip axis is substantially equal to the turning radius of the arm. Form a triangle with the pivot axis of the frame and the distance between the slider as the base, the arm turning radius and the length between the slider and the arm tip axis on both sides, the slider moves along the upper rail, the door panel rotates, and the frame moves. Can turn. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 shows an embodiment of a sliding door apparatus according to the present invention, which can be attached to a frontage and opened and closed. In the figure, 1 is a door panel, 2 is a frame, 3 is an upper rail, and 4 is a slider. The upper rail 3 has a U-shaped cross section opened downward, and is attached to the upper part of the frontage. It can be loosely fitted on the upper rail 3 and moved. That is, the door panel 1 is restrained so as to be movable along the upper rail.

The slider 4 may be formed of a roller which can be loosely fitted on the upper rail 3 and rolled, or may be formed of a cylindrical body which does not rotate. However, the present invention limits the specific structure. is not. For example, a downwardly extending piece may be formed extending downward without forming a loosely-fitting groove having a U-shaped cross section in the upper rail, and a narrow groove in which the hanging piece is loosely fitted may be provided above the slider. However, in this case, the slider must be able to rotate. Therefore, the door panel 1 can move along the upper rail 3 when the slider 4 is loosely fitted on the upper rail 3,
It is also possible to rotate around the slider 4.

On the other hand, a U-shaped frame 2 is provided on one side of the frontage.
Is attached and can be turned. An upper arm 6 and a lower arm 7 extend horizontally at the upper and lower ends of the vertical member 5 of the frame 2, and the ends of the upper arm 6 and the lower arm 7 are connected to the upper and lower ends of the door panel 1 via shafts 8,8. However, the door panel 1 and the upper and lower arms 6, 7 can be bent to each other via the shafts 8, 8. The door panel 1 is supported by one of the upper arm 6 and the lower arm 7, and when the door panel 1 is completely closed, a part of the door panel 1 fits into the frame 2, and as shown in FIG. Is rotated to open the frontage from the frame 2.

Here, the door panel 1 rotates about the slider 4, and the one frame 2 can turn about the axis of the hinge joint attached to the vertical member 5. Of course, it is also possible to pivotally attach via shafts provided at the upper and lower ends of the vertical member without using the hinge. Then, at the same time as the door panel 1 rotates around the slider 4, the frame 2 pivots around the hinge axis, and further, the upper and lower arms 6 and 7 pivot so that the slider 4 can move along the upper rail 3. Radius and arm tip shaft 8
And the distance between the slider 4 is substantially equal.

That is, when the slider 4 is moved to the vertical member 5 and the door panel 1 is opened, the arm pivot axis of the frame 2 and the slider 4 are positioned so that the door panel 1 is positioned substantially perpendicular to the frontage. An isosceles triangle is formed in which the distance between the base and the arm turning radius (the distance between the turning axis of the frame body and the arm end) and the distance between the arm end axis and the slider are both sides. Of course, even if the two sides are not equal, the door panel 1
There is no problem with the opening / closing operation of, but it opens fully in a state inclined to the frontage.

FIG. 2 shows a vertical section of the door device.
The door panel 1 has a shaft 8a hanging from the upper arm 6 of the frame 2.
Is suspended. Of course, it is located on the same axis as the shaft 8b provided at the tip of the lower arm 7, and can be bent around both shafts 8a and 8b. A part of the upper arm 6 is cut out, and the thrust bearing 1
The shaft 8a is attached with a zero interposed therebetween. The shaft 8
a is fixed to the upper reinforcement member 11 of the door panel 1, and the door panel 1 is suspended from the shaft 8a. And axis 8
Since a can freely rotate through the thrust bearing 10, the upper arm 6 and the door panel 1 can bend around the axis 8a.

Similarly, a shaft 8b is attached to the lower arm 7, and the shaft 8b is on the same line as the shaft 8a, and is fixed to the lower reinforcing member 12 of the door panel 1. Of course, axis 8
b can also rotate with respect to the lower arm 7. However, since the lower arm 7 does not need to support the weight of the door panel 1, its strength is small and serves only to position the lower end of the door panel 1. It is also possible to support the lower arm 7 with the door panel 1 placed thereon, but in this case, it is necessary to increase the bending strength of the lower arm 7 by making it thicker. The gap with the surface increases accordingly. Therefore, in terms of appearance, a supporting form in which the door panel 1 is suspended by the upper arm 6 as in the embodiment is more preferable.

The slider 4 is provided at the tip of a receiving base 13 attached to the upper end of the door panel 1.
Reference numeral 3 protrudes from the surface of the door panel 1, and a roller 15 is rotatably supported on a shaft 14 erected on a receiving base 13. The slider 4 configured as described above is loosely fitted to the upper rail 3 and the slider 4 is accommodated in the upper rail 3 regardless of the position where the door panel 1 is rotated.

FIG. 2 is a longitudinal sectional view when the door panel 1 closes the frontage. If the surface of the door panel 1 is pressed, the door panel 1 rotates around the slider 4 and at the same time, the frame 2
Will also be turning. Then, the door panel 1 is moved to one side and the frontage is opened with the pivotal movement of the arm of the frame 2. As described above, the sliding type door apparatus of the present invention supports the door panel by the upper and lower arms of the frame attached to one side of the frontage, and attaches the slider to the upper end of the door panel, and the slider slides on the upper rail. The following effects can be obtained.

[0018]

According to the sliding type opening / closing door device of the present invention, a U-shaped frame is pivotally mounted on one side of the frontage, and the door panel is supported by the upper and lower arms of the frame so that the door panel can be rotated. The upper end is provided with a slider, and the slider is loosely fitted to an upper rail provided at an upper part of the frontage, so that a smooth opening / closing operation can be performed even with a large door panel. That is, the door panel is rotated and moved to one side only by pressing the door panel surface, and the frontage can be largely opened. Therefore, even a physically handicapped person in a wheelchair does not have any trouble in opening and closing the door, and since there is no guide groove on the floor surface, there is no accumulation of dust and no obstacle. .
