Description

[Detailed description of the invention] This invention relates to a horizontally pulling type hanger door that connects a foldable seat door to a hanger door whose width is narrower than the opening width of a building. The purpose of this system is to enable the door to open and close at a faster speed, thereby minimizing the amount of time the door is open, thereby preventing wasted energy due to indoor and outdoor ventilation.

Conventionally, when a single-piece hanger door is used for a large opening as shown in Figure 1, the storage space required is equal to the width of the opening, and the weight of the door is also large, making it difficult to open and close manually. In the case of an electric type, there are drawbacks such as the need for a large motor, and the structure is not suitable for increasing the opening/closing speed.

In addition, as a method to overcome the disadvantage of increasing the storage space, there have been cases in which several doors are divided (see Fig. 2), but this structure requires parallel upper and lower rails equal to the number of doors. Especially when electric
The drawback was that the drive device was complicated.

Therefore, a door with only a seat can be considered,
Opening and closing is unstable if only the upper part is driven.
In addition, problems such as strength against wind pressure and warping due to wind pressure remained, making it impossible to use it as a door with a wide opening.

None of these conventional doors require a fast opening/closing speed, and a large amount of thermal energy is wasted due to indoor/outdoor ventilation.

The present invention solves the above-mentioned problems all at once, and in particular provides an energy-saving door that can open and close at a faster speed, thereby preventing ventilation between indoor and outdoor areas as much as possible. An example of this will be described below. In FIGS. 3 to 5, 1 is a hanger door, and 2 is a seat door connected to the rear of the hanger door 1. One end of the sheet 4 forming the seat door 2 is fixed to the side edge of the hanger door 1 with a bolt or the like via a sheet presser bar 7, and the other end is a tension device 27 made of an elastic body 27a such as rubber or a spring. is fixed. The seat door 2 has a plurality of reinforcing ribs 3 attached at regular intervals.
It is held between the front and back of the sheet 4 by. The reinforcing bone 3 is made of two square pieces 3a, 3 as shown in Fig. 4.
A hanger roller 5 is attached to one end of one of the two square pieces 3a, and a lower guide roller 6 is attached to the other square piece 3b. Although this example shows the case of a single sheet, a divided sheet may also be used (the fifth
figure).

10 is a roller support bracket, angle 12
A cylindrical boss 11 is fixed to the outside of one side of a. The boss 11 is provided with a female thread, into which the spindle 5a or 6a of the hanger roller 5 or the lower guide roller 6 is screwed. Further, a rubber roller 15 is attached to the outer periphery of the boss 11 with a retaining ring 17 via a flat washer 16. When the seat door is opened and the seat is folded, this rubber roller 15 is attached to the front and rear reinforcing ribs 3.
This is to prevent them from coming into contact with each other and causing damage or noise. The hanger roller 5 is screwed onto such a roller support bracket 10,
Attach this to the upper end of the square piece 3a. Similarly, a lower guide roller 6 is screwed and attached to the lower end of the square timber 3b. These square pieces 3a and 3b constitute a pair of reinforcing ribs 3, and the sheet 4 is held between the square pieces 3a and 3b from the front and back and fixed with screws 9.
In this case, the center of the hanger roller 5 and the center of the guide roller 6 are made to coincide with each other, and a plurality of reinforcing ribs 3 made of these square pieces 3a and 3b are attached at a constant pitch suitable for folding the seat door.

The hanger roller 5 runs guided by a square-shaped seat door hanger rail 18 attached to the lower part of the upper I-shaped beam 24, and the guide roller 6 runs along the groove of the lower rail 19. Hanger roller brackets 2 are installed on the left and right sides of the hanger door 1.
1 and 21 are attached (FIG. 4), and a hanger roller 22 is pivotally supported on this bracket 21 and runs on an upper rail 23 for the hanger door. The hanger door upper rail 23 is provided by fixing something such as flat steel to the upper I-shaped beam 24.

A chain bracket 31 is attached to the center of the hanger roller brackets 21, 21. The tip of the chain bracket 31 is, for example, the first
By the mechanism shown in FIG. 1, it is wound around a sprocket 25 and fixed to a chain 26 driven by a drive motor (not shown). Further, two guide pieces 32 (front and rear) are attached to the lower part of the hanger door 1, which travel guided by the lower rail 19 to prevent the hanger door 1 from swinging.

FIG. 12 shows another embodiment of the tensioning device 27.
This has a coil spring 29 installed vertically between two upper and lower chains 28, 28, and the chain 28 is installed between the reinforcing bone 3 at the rear end and the frame 30. Chain 28 when door is fully closed
By making the seat door V-shaped, tension is applied to the seat door in the closing direction when the door is fully closed, thereby preventing the seat door from sagging.

With the above configuration, only the preceding hanger door 1 in the horizontal sliding door is driven via the chain 26, and the seat door connected and reinforced by the reinforcing rib 3 is connected to the rear of the hanger door 1. Only. Therefore, 1. When the hanger door is driven and closed, the seat door is folded, so the storage size can be small.

2. Since only the hanger door needs to be driven, it is mechanically and dynamically advantageous.

3 The hanger door and seat door are connected, but only one lower rail is required.

4. Since the overall weight of the horizontal sliding door is lighter, it is suitable for high-speed opening and closing and is easy to drive.

5. By increasing or decreasing the number of sheets 4 and reinforcing bones 3, it is possible to easily accommodate openings of various sizes, making it particularly suitable for large openings.
