Description

  The present invention relates to a folding door support structure for folding doors composed of two panels.

  FIG. 3 is an external view of a folding door device to which the present invention is directed. (A) is a folding door (A), (B) is folded and (i) is opened, and (b) is a folding door (A), (B ) Is extended and the window is closed. The folding door (b) is composed of two panels, a door side panel (b) and a suspension side panel (c). The folding doors (b) and (b) form a pair to form a frame (d) Installed.

  Here, the door side panel (b) and the suspension side panel (c) are connected via a joint (e) so that they can be folded, and connected to the suspension side of the suspension side panel (c) The hanging hooks connected to the frame (d) can be slid along the upper and lower bars of the frame (d). Therefore, the window can be opened and closed by sliding the tip of the door-end side panel (b).

  By the way, the upper and lower ends of the suspension hook connected to the suspension base side of the suspension side panel (c) are connected to the frame body (d), but connected to the tip of the door side panel (b). There is a case where the door toe is hung on the upper rail provided on the upper rail by a hanging car, or the lower door car is placed on the lower rail provided on the lower rail. In general, there are many cases where a suspension car is attached to hang the door toe. However, in the structure in which the upper rail is provided on the upper rail and suspended, the strength of the upper rail is required. However, the strength of the upper rail provided on the frame body may not be sufficiently obtained due to the structure of the building.

  4A and 4B show a cross section of a folding door device provided with a suspension wheel, wherein FIG. 4A is a transverse sectional view when the folding door (A) is extended, and FIG. 4 (B) is a crossing when the folding door (I) is folded. A top view and (c) are the longitudinal cross-sectional views showing the front-end | tip part of the door-end side panel (b). As shown in (c) of the figure, a suspension wheel (f) is attached to the upper end of the front door rod (chi) and can move on the upper rail (g).

  The door-end rod (H) and the door-end side panel (B) are connected via a joint, but when the folding door (a) is folded, if it extends in the opposite direction, the moment is centered on the joint. Occur. FIG. 5 shows a moment generated when folding the folding door (A), and for this purpose, the suspension wheel (F) mounted on the upper rail (G) is guided so as not to derail. In the case of a suspension wheel (f), the structure is provided with rollers on both sides, so that it can resist the moment. However, in the case of the folding door (a) provided with a lower door as a lower support structure, a special structure is required so as not to remove the wheel.

  The “folding door” according to Japanese Patent Application Laid-Open No. 2002-242517 is provided with a door pulley and has a support structure, and can reliably prevent the door wheel from being removed from the guide rail. In view of this, a door pulley device including a door roller and a guide roller that can come into contact with the interior and exterior surfaces of the guide rail is provided on the lower side of the folding door. For this reason, even if a large rotational force is applied to the summoning bowl, such as when a heavy weight shoji connected to the summoning bowl is folded vigorously, the guide roller contacts the guide rail against this rotational force. This can definitely be countered. Therefore, the door wheel only needs to support a vertical load, and the door wheel does not escape from the guide rail with such a rotational force.

When the folding door (I) opens and closes, the tip of the door end side panel (B) slides along the upper and lower rails and rotates. That is, it slides while rotating. Therefore, there is a possibility that the undercarriage may come off from the lower rail (guide rail), and a structure that can prevent this is required. The “folding door” according to Japanese Patent Application Laid-Open No. 2002-242517 includes a guide roller that can sandwich a guide rail.
"Folding door" according to JP-A-2002-242517

  As described above, the folding door provided with the undercarriage cannot be removed from the guide rail by having the guide roller. However, the guide roller requires a total of four guide rollers, front and rear and left and right, to sandwich the guide rail. This necessarily increases the cost. Also, dust accumulates in the corners of the guide rail that stands up from the base, and it is troublesome to remove it. The problem to be solved by the present invention is this problem, and provides a folding door support structure capable of smoothly opening and closing the folding door even if the number of guide rollers is reduced.

The lower door apparatus constituting the folding door support structure according to the present invention is constituted by one lower door car and two guide rollers, and is easily and accurately attached to the lower end of the door-end fence and the lower end of the suspension base fence. It has a structure that can. Here, the basic form of the folding door to which the undercarriage device is attached is configured so that the suspension side panel and the door end side panel can be folded via a joint, and the suspension side panel is suspended on the suspension side of the suspension side panel. The main shaft is connected and fixed to the frame body, and the door-end rod is attached to the tip of the door-end side panel via a joint.

  By the way, the lower door cart is rotatably supported at the center bottom of the substrate, and a guide roller is axially supported in the front and rear (moving direction) of the lower door cart. A side plate rises at the front end of the substrate, and a lower door cart device is attached to the lower ends of the door toe and the suspension base with the substrate and the side plate. In other words, the substrate is brought into contact with the lower ends of the door toe and the hanging base and the side plates are fixed to the side surfaces of the door toe and the hanging base. This undercarriage device is configured as an independent part that is completely separated from the folding door, and can be attached to a door-end fence and a suspension base fence via a substrate and a side plate.

  On the other hand, the lower rail is integrally formed as a part of the lower rail of the frame, and is continuous through the inner guide wall and the inclined portion. The outer guide wall has a guide groove having a predetermined width between the outer guide wall and the inner guide wall, and the guide roller is loosely fitted in the guide groove. That is, the lower door carriage is placed on the lower rail, and both guide rollers can be fitted in the guide grooves. And the drain hole is provided in the lower part of the outer guide wall in some places.

The undercarriage device constituting the folding door support structure of the present invention has guide rollers in the front and rear (moving direction) of the undercarriage, so that the undercarriage rests on the lower rail and the two guide rollers are guide grooves. Loosely fitted. Therefore, the lower door cart does not fall off the lower rail. In the case of the present invention, in order to prevent the undercarriage from being removed, two guide rollers that fit into the guide groove may be used. Therefore, the structure is simple and the cost is low.

  The undercarriage device of the present invention is configured independently of the folding door, and has a board and a side plate standing at its tip, so that it is correctly positioned at the lower ends of the door toe and the suspension base and can be easily removed. I can wear it. On the other hand, the lower rail has guide walls on both sides thereof, and a guide groove into which a guide roller fits is formed between both guide walls. Furthermore, the inner guide wall and the lower rail are connected by an inclined wall, and therefore, dust does not accumulate on the lower rail and does not hinder the traveling of the lower door cart. That is, the dust collects in a space provided below the lower rail, and the dust collected in this space flows out from a drain hole formed in the lower portion of the outer guide wall together with rainwater.

FIG. 1 is a specific example showing an undercarriage apparatus constituting a folding door support structure according to the present invention. In the figure, 1 is a substrate, 2 is a side plate, 3 is a lower door wheel, and 4 is a guide roller. The substrate 1 has a rectangular shape, and a side plate 2 stands upright from the tip of the substrate 1, and the side plate 2 has a U-shaped cross section. Both ribs 5 and 5 extending downward from both sides of the substrate 1 are provided, and the lower door wheel 3 is rotatably supported by a horizontal shaft 6 provided on the ribs 5 and 5. On the other hand, the guide rollers 4 and 4 are rotatably supported on vertical axes provided in the front and rear (moving direction) of the lower door cart 3. Moreover, in order to absorb the impact at the time of folding a folding door, the cushion material 7 is attached to the back end.

  Thus, in the present invention, the undercarriage device can be configured as a part independent of the folding door, and can be attached to the tip of the folding door via the substrate 1 and the side plate 2. It can also be attached to a hanging lantern at the rear end of a folding door. FIG. 2 shows an embodiment of the support structure of the door toe according to the present invention, in which the lower door car device is attached to the lower end of the door toe 8 and is supported on the lower rail 9. The undercarriage 3 is attached to the lower end of a door-end fence 8 connected to the tip of the door-end side panel 10 via a joint. In this case, the substrate 1 abuts on the lower end of the door-end fence and the side plate 2 is a door. It is screwed into a hole formed in the tip 8.
