Description

[Detailed Description of the Invention] The present invention relates to a seat reinforcement structure for a seat door in a horizontal sliding door in which the seat door is connected to a hanger door.

In particular, the sheet is sandwiched between front and back sides using reinforcing square pieces of the same shape, and a hanger roller can be attached to the top of one square piece, and a lower guide roller can be attached to the bottom of the other square piece, so that the reinforcing bones of the sheet can be attached at the same time. This relates to a reinforcing structure that also serves as upper and lower roller mounting members.

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 ventilation between the interior and exterior.

The applicant has previously devised a horizontal sliding door that can solve the above-mentioned problems all at once, and filed an application at the same time as the present application. According to this, the opening and closing speed can be increased,
This makes it possible to provide an energy-saving door that can prevent indoor and outdoor ventilation as much as possible. The present invention relates to a seat connection structure for a seat door in a horizontal sliding door, and embodiments thereof will be described in detail below.

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. Fixed. The seat door 2 is held between the front and back of the seat 4 by a plurality of reinforcing ribs 3 attached at regular intervals. The reinforcing bone 3 is made of two square pieces 3 as shown in Fig. 4.
It is composed of a and 3b, but the square timber 3 of these two
A hanger roller 5 is attached to one end of the block a, and a lower guide roller 6 is attached to the other square piece 3b. The sheet may be a single sheet or divided sheets connected together with reinforcing square members as shown in FIG. 12.

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, causing damage and 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 reinforcing frame 3 as a pair, 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 guide roller 6
These square pieces 3a and 3
A plurality of reinforcing ribs 3 made of B 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 upper 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
It is wound around a sprocket 25 by the mechanism shown in FIG. 1, and is driven by a drive motor (not shown). It is fixed to the chain 26. 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.

With the above configuration, only the preceding hanger door 1 of the horizontal sliding door is driven via the chain 26, and the rear of the hanger door 1 is connected with the reinforcing frame 3 and the reinforced seat door is connected. There is only one.

As explained above, the seat door connected to the hanger door is reinforced by the reinforcing rib according to the present invention and can be opened and closed rapidly without any problems, and has the following effects. be.

1. The square timbers constituting the reinforcing bones 3 can be exactly the same on the front and back.

2. When several doors of different heights are delivered to the site, it is possible to prepare a square piece with the largest opening height as a spare with a roller support bracket attached, so that it can be replaced in case the reinforcing bone is damaged. If necessary, all opening heights can be accommodated by cutting down the side opposite to the boss.

3. Composition of the reinforcing bone Since the square timbers can be assembled regardless of their dimensions, any square timber or flat bar can be used as the reinforcing bone component in consideration of wind pressure resistance.

4 No special processing is required for the sheets used. Assembly is easy as only drilling is required.
