Description

[Detailed Description of the Invention] The present invention relates to a running device for a door car that enables smooth opening and closing of folding storm doors.

As houses become more Western-style, so-called folding shutters, which have a hinge structure in which multiple shutters are folded and attached to a wall, are becoming more popular, instead of the conventional type that is stored in a door pocket. By the way, in conventional folding storm doors, a separate member with a groove called a turntable is connected to the end of the rail, and a guide block is attached to the bottom of the door plate to allow the door plate to be folded and stored. . However, with this structure, the guide block simply slides into the groove, which often makes it difficult for the door roller to run at the rail joints, or makes it difficult to open and close the shutters. Therefore, the present inventor completed a seamless rail structure by fitting a one-piece rail with a curved end at the end as described later into the storm door rail section of a ready-made one-piece frame sash. The present invention provides a running device for a door roller installed at the tip of a storm door that enables smooth opening and closing in such a rail structure.

The structural features of the door-to-door vehicle running device of the present invention are as follows. That is, the door roller running flat part 26, the rising edge 10 provided substantially perpendicularly from the flat part, the hanging edge 11 hanging down from the rising edge 10 at a predetermined interval, and the area between the hanging edge and the rising edge. A lower rail 9 consisting of a door roller guide portion 12 formed therein.
The door wheel for a folding storm door is attached to a rail section 8 for a folding storm door, which is provided with a bearing block having a substantially square cross section and rotatably attached to the lower part of a vertical stile at the tip of the storm door with a mounting pin 24. , is cantilever-supported by a horizontal shaft on the inner surface of the bearing block, and the door roller running flat portion 26 of the lower rail is inserted through a loop hole 28 in the bottom side 27.
A folding rain door comprising a door roller 21 that looks upward, and two door roller guide rollers 23 that are rotatably supported by a vertical shaft to the end of the bottom surface 27 of the bearing block and roll within the door roller guide section 12. This is a door-to-door vehicle running device.

This will be explained in detail below with reference to the drawings.

Figure 1 is a front view of a double folding storm door using the door door vehicle running device of the present invention, and Figure 2 is a front view of a double folding storm door using the door door vehicle running device of the present invention.
An enlarged cross-sectional view of A-A in the figure, Figure 3 is B-B of Figure 1.
It is an enlarged cross-sectional view. FIG. 4 is a perspective view of the door wheel according to the embodiment of the present invention.

As is clear from these figures, this double-opening folding rain door has four door panels 1a to 1d attached to a conventional integral frame sash 2 . The four door panels can be opened both ways from the center to the left and right. For this purpose, the two door panels 1a and 1b on the left side of the center are foldably connected by hinges 3 and 3, and the leftmost end is rotatably supported using upper and lower pivot pins 4, 4. . The two door panels 1c and 1d on the right have a similar structure,
The hinges 5, 5 and pivot pins 6, 6 allow for folding and rotation in the right direction. Of course, by using the moving device for the door car of the present invention, it is possible to create a storm door with a structure in which two door panels can be folded only in either the left or right direction, and it is also possible to optionally increase the number of door panels to create multiple folding shutters. It can be implemented.

If the specially constructed lower rail 9 as described above is used for such a storm door, it will be easy to open and close and will have good durability. The rail structure can be seen in FIGS. 2 and 3. This lower rail 9 has a structure that can be fitted into the shutter rail part 8 of the lower frame 7 of the integral frame sash used for ready-made sliding shutters, and has a flat part 26 for running the door roller, and a flat part 26 for running the door roller. The cross section consisting of a rising edge 10 provided substantially perpendicularly from the flat part and a hanging edge 11 hanging down from the rising edge 10 at a predetermined interval is approximately 0-shaped, and the rising edge 10 and the hanging edge 11 are Thus, a door roller guide portion 12 is formed, and the end portions are made to protrude to the left and right of the frame and are curved outward to form curved end portions 13. As shown in FIG. 3, the upper rail 14 is provided at the upper part of the door plate and has a structure on which a guide roller 15 rolls, and is also fitted and attached to the shutter rail part 17 of the upper frame 16. The curved end 1 of the lower rail 9
It is curved so that it is parallel to 3. There is also a known door roller guide section 12 that is formed integrally with the window lower frame, as described in, for example, Japanese Utility Model Application No. 167230/1983.

Here, the door front door wheel 18 of the present invention will be explained. As shown in Fig. 1, the door wheel 18 is attached to the lower part of the end panels 1b and 1c of the shutter, which is made up of a plurality of panels connected by hinges, and supports the weight of the panels when they are opened and closed. , has the function of moving on the lower rail to move the door forward or backward. The door wheel 18 of the present invention has a special structure that has not been seen before, and examples thereof are shown in FIGS. 3 and 4. As seen in these figures, the door wheel 18 of the present invention has a door wheel 21 cantilevered by a horizontal shaft 20 on the inner surface of a bearing block 19 having a substantially square cross section, and a bottom surface 2.
The door roller 21 is mounted so as to look through the loop hole 28 of the lower rail onto the door roller traveling flat portion 26 of the lower rail, and two door roller guide rollers 23 are pivotally supported to the end of the bottom surface 27 of the bearing block 19 by a vertical shaft 22. , 23 was installed. A mounting pin 24 for attaching to the lower part of the door frame of the storm door is inserted upward into the upper part of the square bearing block 19 equipped with the door roller 21 and the door roller guide roller 23. The bearing block is rotatable.

The door-to-door vehicle of the present invention has the structure as described above.
As shown in FIG. 3, when the two door roller guide rollers 23 are attached to the lower part of the door frame of the shutter, fitted to the door roller guide section 12 provided on the lower rail 9 , and run on the lower rail, Unlike conventional guide rollers, the door roller 21 rotates while supporting the weight of the storm door to enable easy movement of the door plate, and the two door roller guide rollers 23 move in the left and right (horizontal) direction within the door roller guide section 12. Since they move together while their movement is restricted, they move stably within the lower rail and faithfully follow the shape of the lower rail. Therefore, folding or stretching of the door panel can be smoothly performed not only at the straight section but also at the curved end of the lower rail. The effect of installing two door roller guide rollers is not only to restrict the horizontal movement of the door plate when opening and closing, but also to prevent vibrations caused by the wind when the shutter is closed, noise prevention, It also contributes to improving the strength of shutters. In addition,
The present invention is also significant in that it makes it possible to easily attach folding shutters to existing one-piece frame sashes.
