Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device which can be opened and closed by sliding a single large panel. 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. The opening / closing operation is not easy due to the large turning radius. 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. As a device to be mounted on a large wide frontage, there is known a folding door device in which two or three panels are connected to form a folding door, and the frontage can be opened by folding these panels. Have been. Fig. 5 shows a conventional general folding door, but two panels (a),
(B) is connected so that it can be bent by a joint (c), and a hanging frame (d) is provided on the hanging side, and a pulling frame is provided on one door side.
(E) are connected to each other. [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 or 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, guide rails must be laid on the floor surface to guide the lower end of the panel, but there are cases where the floor surface has a groove and becomes an obstacle. Therefore, as a door device which can be easily opened and closed even if the width of the frontage is large, a device in which one large door panel is slid while rotating is known. This is a sliding door device as shown in FIG. That is, this is a door device in which the door panel (f) can move while rotating to open and close the frontage, and an upper rail (g) is provided at the upper part of the frontage, and the upper rail (g) is provided.
A door panel (f) is hung on a hanging truck (h) that moves the wing, and a U-shaped frame (r) is attached to one side of the frontage so as to be pivotable, and the upper and lower arms ( (G) A slide type door device in which the tip is connected to the upper and lower ends of a door panel (f) via shafts (e) and (e). [0007] The use of this sliding door device is not particularly limited, but when the frontage is opened, the door panel moves to the frame side so that the hanging wheel hits a stopper located at one end in the upper rail. . If the frontage frame is fitted in the frontage as shown in FIG. 6, it is relatively tough, but if it is used for the entrance of a toilet or the like partitioned by the partition panel, a hanging vehicle with a large door panel hung. The upper rail and the sash to which the upper rail is attached are twisted based on the impact when the door hits the stopper, while the lower end of the door panel is bent and deformed by inertia and swings. [0008] In the case where a strong frontage frame cannot be fitted to the frontage as described above, for example, a large slide-type opening / closing door device is installed at the entrance of a toilet, as described above. There is. The problem to be solved by the present invention is this problem. To provide a sliding-type opening / closing door device in which an upper rail or a cap is not twisted by an impact when the door panel is opened, and the door panel is not bent. . [0009] The sliding door device of the present invention is constructed so that one large door panel can be mounted on the frontage and can be opened and closed. The basic structure is as follows. Common to conventional ones. In this case, a partition panel is installed at a predetermined distance from the frontage, and a cap is stretched over the upper end between both panels. The upper rail on which the hanging vehicle that hangs the door panel travels is attached to the lower side of the casket. The U-shaped frame body which is connected to the upper and lower ends of the door panel and rotated is attached to the inner end of the partition panel via a hinge or the like so as to be swingable. Therefore, an L-shaped reinforcing material is fixed to the corners of the upper rail and the inner end of the panel so that the upper rail and the coping are not twisted by an impact when the door panel is opened,
Fix the upper rail directly to the partition panel. On the other hand, a stopper is attached to the lower end of the partition panel so that the lower end of the opened door panel contacts the stopper. Therefore, the hanging vehicle hits the upper stopper attached so as to be located in the upper rail, and stops when the lower stopper attached to the lower end of the partition panel hits the lower end of the door panel, thereby eliminating the bending due to the inertia of the door panel. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. 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 drawing, reference numeral 1 denotes a door panel, 2 denotes a frame, 3 denotes an upper rail, and 4 denotes a suspension car. The frontage is made of left and right partition panels 5, 5 at predetermined intervals. This frontage is an entrance in the case of a toilet booth, and the door panel 1 is attached to close the entrance. The upper rail 3 is attached to the lower side of the upper panel 3 between the two partition panels 5 and 5. The sliding-type opening / closing door device shown in FIG. 1 does not have a front frame as shown in FIG. 6, the U-shaped frame 2 is directly attached to the inner end of the partition panel 5, and the upper rail 3 is also a skirting. 6 is attached directly. The hanging vehicle 4 can move on the upper rail 3, and the door panel 1 is suspended from the hanging vehicle 4, and the hanging vehicle 4 is positioned substantially on the center axis of the door panel 1, and the door panel 1 is moved relative to the hanging vehicle 4. Can rotate. Although the type of the hoisting wheel 4 is not particularly limited, a roller which can be rolled on the traveling piece of the upper rail 3 is supported by a shaft, and a door shaft is provided on a hanging shaft extending downward from the main body of the hoisting vehicle. 1 is connected. The frame 2 has a U-shape, and an upper arm 8 and a lower arm 9 extend horizontally at upper and lower ends of a vertical member 7. And the tip of the upper and lower arms 8, 9 is the shaft 10,
The door panel 1 is connected to the upper and lower ends of the door panel 1 through 10, so that the door panel 1 and the upper and lower arms 8 and 9 can bend each other through the shafts 10 and 10. In a state where the door panel 1 is completely closed, a part of the door panel 1 fits into the frame 2, and the door panel 1 rotates to separate from the frame 2 to open the frontage as shown in FIG. 1. Here, the door panel 1 rotates around a suspension shaft extending downward from the suspension vehicle 4, and the one frame 2 pivots around an axis of a hinge joint attached to the vertical member 7. Can be done. 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 suspension wheel 4, the frame 2 pivots around the hinge axis,
Further, the turning radii of the upper and lower arms 7 and 8 and the distance between the arm tip shaft 10 and the hanging vehicle 4 are substantially equal so that the hanging vehicle 4 can move along the upper rail 3. FIG. 2 shows a longitudinal section and a transverse section of the apparatus. The hanging wheel 4 supports rollers 12, 12 on both sides of the main body 11, and these rollers 12, 12 are connected to the running piece 1 of the upper rail 3.
3, 13 can be rolled and moved. A guide roller 14 is rotatably supported at the upper part of the main body 11, and a suspension shaft extends downward so that the door panel 1 is connected and suspended. The upper arm 8 and the lower arm 9 are connected to the upper and lower ends of the door panel 1 to rotate the door panel 1. Although the door panel 1 is suspended from the suspension vehicle 4, the door panel 1 is connected to the upper and lower arm tip shafts 10, 10 at a predetermined distance from the suspension vehicle 4, so that a stable opening and closing operation is performed. That is, the door panel 1 does not swing by itself, and the door panel 1 moves along the upper rail 3 while rotating. Here, the lower arm 9 can also function to support a part of the weight of the door panel 1. FIG. 2B shows a case where the door panel 1 is completely closed. The front end of the door panel 1 hits a door stop 15 a provided at the inner end of the partition panel 5, and the door panel 1 also contacts the side end of the door panel 1. The door stop 15b is also in contact with the vertical member 7 of the frame 2. Reference numeral 16 in the figure denotes a stopper, and the partition panel 5
The stopper 16 is attached to the lower end of the. This is a stopper for contacting the lower end when the door panel 1 is opened. The upper end is adapted to hit a stopper (not shown) provided by the suspension vehicle 4 in the upper rail. Conversely, a cushioning material may be attached to the suspension vehicle 4 itself. FIG. 3 shows a locus when the door panel 1 is opened. As described above, the door panel 1 moves while rotating, and the frontage is opened. When the door panel 1 is completely opened, the hanging wheel 4 hits the stopper disposed in the upper rail 3 and the lower end of the door panel 1 is connected to the stopper 16. Abut. On the other hand, the door panel 1 can stop by contacting both stoppers. However, the door panel 1 is pulled by the frame 2 by the movement of the U-shaped frame 2 and acts as an external force on the side surface of the upper rail 3. Therefore, although the upper rail 3 is attached to the coping 6, since the upper rail 3 is rolled and is not stable, the L-shaped reinforcing member 17 is fixed as shown in FIG. 4 in the present invention. The L-shaped reinforcing member 17 fixes the upper piece 18 to the upper rail side and fixes the vertical piece 19 to the inner end of the partition panel 5. Therefore, the upper rail 3 is supported by the partition panel 5 and does not roll. As described above, the sliding-type opening / closing door device of the present invention has a door panel suspended from a suspension vehicle which moves on an upper rail attached to a lower side of a casket, and is pivotally attached to one side of the frontage. Connect the upper and lower ends of the door panel to the arm of the U-shaped frame body, provide a stopper for the hanging rail on the upper rail, and a stopper for the lower end of the door panel on the lower end of the partition panel, and at the corner of the upper rail and the inner end of the partition panel. Is a fixed L-shaped reinforcement,
The following effects can be obtained. According to the sliding type opening / closing door device of the present invention, the door panel is hung by the hanging vehicle moving on the upper rail, and the upper and lower arms of the U-shaped frame are connected to the upper and lower ends of the door panel. Further, if the surface of the door panel is pressed, the door panel rotates with the rotation of the frame, and the door panel slides by the rotation of the frame to open the frontage. Therefore, even for a large door panel, a large force is not required for opening and closing the door panel. For example, even a physically handicapped person in a wheelchair can easily open and close the door. When the large door panel is opened, the hanging vehicle hits a stopper provided on the upper rail, and the lower end of the door panel comes into contact with a stopper provided at the lower end of the partition panel, whereby the door panel shakes or bends due to inertia. Open without any. Also, when opened, it will be pulled by the arm of the frame and will push the hanging car in the lateral direction,
Since the end of the upper rail is fixed to the inner end of the partition panel by the L-shaped reinforcement, the upper rail does not roll or twist.
