DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device which is mounted between an upper frame and both vertical frames to open and close.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional sliding door device.
The two sliding doors (a) and (b) are mounted between the lower frame (b) and the upper frame (c) so that they can slide. In other words, the front door is slid to open and close,
The rail (d) is embedded in the upper surface of (b), and the door (e) attached to the lower end of the sliding door (a) is embedded in this rail (d).
There is. The cross-sectional shape of the rail (d) is various and is not limited to the case shown in the figure, but the upper surface of the rail (d) forms a V shape so that the door (e) does not come off.

A guide groove is provided on the lower surface of one of the upper frames (Kamoi).
(F) is formed, and a guide piece formed at the upper end of the sliding door (b)
(G) is loosely fitted. The sliding door (a) is slidable by being restricted by the rail (d) and the guide groove (c). In this case, the upper frame (c) has a thickness H to form the guide groove (f). ₁ is larger than the thickness H ₂ of the bottom rail (b).
Therefore, the lower frame (b) and the upper frame (c) cannot be manufactured by using the same size of timber, and the upper frame (c) uses the thicker timber, and the guide grooves (f), (f) Must be processed.

Further, the sliding door device is provided with vertical frames on both sides of an upper frame (c), and the thickness of the vertical frames is almost the same as the lower frame. Therefore, since only the upper frame has a large thickness, the same square member cannot be used. However, depending on the sliding door device, the frame may be constituted only by the upper frame and both the left and right vertical frames without using the lower frame. In this case, the rail is attached to the base plate surface.

[0005]

As described above, since the guide groove is formed in the upper frame of the conventional sliding door device, the rectangular frame is thicker than the lower frame and both vertical frames in order to prevent the strength from being reduced. Must be used. The problem to be solved by the present invention is this problem, and provides a sliding door device using a square material having substantially the same thickness as a lower frame and a vertical frame as an upper frame.

[0006]

The sliding door device of the present invention comprises a frame having a lower frame, an upper frame, and both vertical frames, and a sliding door is mounted on the frame and slides to open and close the frontage. Can be done. Rails are buried in the lower frame to slide the sliding door, and rails are also mounted in the upper frame. That is, the rail is used in the same manner as the lower frame without forming a guide groove in the upper frame, but is mounted in a state protruding from the lower surface without being embedded in the upper frame.

The rail attached to the upper frame is for guiding the upper end of the sliding door. For this purpose, a concave guide groove is formed on the upper surface of the sliding door, and the rail fits into this guide groove. . The rail has an anchor-shaped fastening portion at the upper part thereof, and the fastening portion is fitted and attached to a narrow groove formed on the lower surface of the upper frame. In this case, the upper frame uses a timber having substantially the same thickness as the lower frame and the vertical frame. On the other hand, in the sliding door device of the present invention, a gate-shaped frame may be constituted by the upper frame and both vertical frames without using the lower frame, and in this case, a rail is attached to the main plate. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 is an embodiment showing a sliding door apparatus according to the present invention. The basic structure is the same as that shown in FIG. 3, and the upper frame 1, lower frame 2 and both vertical frames (not shown)
A sliding body 3 is mounted on the frame. The upper and lower frames 1, 2 are square members having a rectangular cross section, and the thickness H is the same for both the upper and lower frames and the vertical frame. Two lower rails 4 are buried on the upper surface of the lower frame 2 and are parallel to each other, and a V groove is formed on the upper surface of the lower rail.

One upper frame 1 has two upper rails 6, 6 attached in parallel to a lower surface 5 thereof. The upper rail 6 is not embedded in the upper frame 1 but protrudes from the lower surface 5, and a fastening portion 7 formed on the upper rail 6 is fitted into a narrow groove formed on the lower surface 5 of the upper frame 1. . FIG. 2 shows a case where the upper rail 6 is represented alone, and the fastening portion 7 protrudes above the rail body 8 having a square cross section. The fastening portion 7 has a squid-shaped shape so that it does not come off when fitted in the groove.

The sliding door 3 has a door wheel 9 attached to the lower end thereof. The door wheel 9 is positioned by fitting into the V groove of the lower rail 4, and the upper end of the sliding door 3 is positioned by the upper rail 6. A concave guide groove 10 is formed on the upper end surface of the sliding door 3, and the upper rail 6 is fitted into the guide groove 10.

Here, the groove formed on the upper surface of the lower rail 4 is not limited to the V-shaped groove, and as shown in FIG.
Can also be provided. Therefore, the shape of the door wheel attached to the lower end of the sliding door in this case is the concave groove 1 in which the convex portion 11 is fitted.
2 will be formed.

Although the sliding door device shown in FIG. 1 constitutes a frame having upper and lower frames and both vertical frames, a portal frame may be used without using the lower frame. In this case, the lower rail 4 supporting the sliding door is directly attached to the main plate, and is arranged on substantially the same surface as the floor plate bonded to the main plate surface. As described above, the sliding door device of the present invention has the upper rail attached to the upper frame as well as the lower frame, and the following effects can be obtained.

[0013]

According to the sliding door apparatus of the present invention, the sliding door is mounted on the frame composed of the upper and lower frames and both vertical frames, or the gate frame composed of the upper frame and both vertical frames. Has no guide groove as in the prior art, and has an upper rail attached. Therefore, the strength of the upper rail is not reduced by the guide groove, and the upper frame can be made of the same thickness as the lower frame or the vertical frame. This saves material and also reduces the man-hours required for fabrication because no large guide grooves need to be machined. In addition, since the upper rail is made of resin, the sliding with the guide groove formed at the upper end of the wooden sliding door is improved, and the sliding door can be opened and closed smoothly. On the other hand, in the sliding door device of the present invention that guides the upper end of the sliding door by the upper rail attached to the upper frame, the vertical cross section is symmetrical,
Since the appearance is the same from either side, it can be constructed without considering the direction of the entrance.
