Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem: a conventional interlocking sliding door has an interlocking device of a large vertical length, and therefore an inspection window exhibits a conspicuously large length, to thereby fail in exhibiting a good appearance of the sliding door. <P>SOLUTION: There is provided a new interlocking sliding door which is improved in the following two points. Firstly, the new interlocking sliding door has a horizontally arranged rack-and-pinion structure in place of a vertically arranged rack-and-pinion structure of the conventional interlocking sliding door, and a pinion (6) is horizontally arranged on an upper end face of a sliding door 2(2), followed by engaging a rack with the same. Secondly, the interlocking sliding door is hung directly from a slide rail (11) in place of hanging of the conventional interlocking sliding door from the rail via a sash roller attached to an upper edge of the sliding door. By virtue of the above-mentioned two improved points, the vertical length of the interlocking device is reduced. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an interlocking sliding door that is attached to a doorway of a building or a room and opens the second sliding door in conjunction with the opening of the first sliding door.

As shown in Fig. 2, the conventional interlocking sliding door has a car (3) attached to the upper part of the sliding door 1 (1) and the sliding door 2 (2), and these are mounted on the two rails (4) and suspended. Yes. At this time, the movable rack (5) is attached to the sliding door 1, the pinion (6) is attached to the sliding door 2, and the fixed rack (7) is attached to the upper frame (8). The fixed rack is engaged with the pinion and the movable rack is engaged with the lower part.
See above (Patent Document 1)

  Next, as shown in FIG. 3, the interlocking sliding door includes a sliding door 1 (1), a sliding door 2 (2), and a fixed door (9) that are roughly divided into three. Therefore, when the sliding door 1 is opened, the sliding door 2 starts to move simultaneously. At this time, the moving distance of the sliding door 2 moves only half of the moving distance of the sliding door 1. Accordingly, the state shown in FIG. 4 is obtained when the half is opened, and the state shown in FIG. Such an interlocking sliding door is characterized by a wide entrance.

Further, this interlocking mechanism will be described with reference to FIG. 6. A is in a state where the interlocking sliding door is closed,
B is a half-open state, and C is a closed state. When the sliding door 1 is moved, the moving rack (5) attached to the sliding door 1 moves while rotating the pinion (6). At this time, the moving distance of the pinion is half of the moving distance of the moving rack. Since the pinion is attached to the sliding door 2, the moving distance of the sliding door 2 always moves only half of the moving distance of the sliding door 1.

The conventional interlocking sliding door has a large vertical width at the interlocking device part, so that only the width of the inspection window (10) in FIG. 2 is conspicuously large, and it cannot be said that the appearance is good.
For this reason, the present invention aims to provide an interlocking sliding door having a good appearance by reducing the vertical width of the interlocking device portion and narrowing the width of the portion having the inspection window.

  First, a conventional interlocking sliding door has a rack and pinion arranged vertically as shown in FIG. 2, whereas in the present invention, it is arranged horizontally as shown in FIG. Then, the pinion was attached horizontally to the upper surface of the sliding door 2, and the rack was meshed with this.

  Here, a case where the rack and pinion is horizontally arranged has been filed, and among them (utility model document 1), as shown in FIG. 8, the pinion (6) is connected to the upper end of the sliding door 2 (2). A cutout is provided in the part, and it is dropped and attached to a position lower than the upper surface of the sliding door. When mounted in this manner, the rack and pinion must be mounted in a narrow space, and the tooth shape of the rack and pinion can only be attached to a small tooth shape.

  Therefore, in the present invention, the pinion is attached to the upper surface of the sliding door 2 as shown in FIG. In this way, since the rack and pinion can be mounted in a wide area, the tooth shape of the rack and pinion can be attached to a large tooth shape.

To explain this in more detail, the thickness of the sliding door is usually 40 mm, and the distance between the sliding doors is 5.5 mm. For this reason, the width (b) for mounting the rack and pinion (utility model document 1) is 51 mm. The rack and pinion attached to this 51 mm width can only be attached to the module 2 tooth profile.
On the other hand, in the present invention, the width (a) for attaching the rack and pinion is 70 mm. When the width is 70 mm, the rack and pinion is attached with the tooth shape of the module 3.
7 shows the module 3 and FIG. 8 shows the pinion of the module 2.

  Therefore, the difference between the module 2 and the module 3 pinion will be described. First, the rack and pinion of the tooth shape of module 2 has a shallow engagement, so if an excessive pulling force is applied to the sliding door, the sliding door will inevitably have a backlash. Things happen.

On the other hand, the tooth-shaped rack and pinion of the module 3 does not disengage even if an excessive pulling force is applied to the sliding door because the engagement is deeper than the backlash of the sliding door. When the pinion is further increased, it is possible to insert a bearing into the pinion to increase durability.
This has been experienced by the Applicant previously making a rack and pinion of the module 2 tooth profile and then succeeding in changing to the module 3 tooth profile.

Secondly, the conventional interlocking sliding door is hung on the rail by attaching a car to the upper part of the sliding door, whereas it is hung on the slide rail (11) in the present invention. This slide rail is as shown in FIG. 1, and can be constructed as a whole with a vertical width much smaller than that of a car.
See above (Patent Document 2)

  Thus, according to the present invention, firstly, the pinion is horizontally attached to the upper end portion of the sliding door 2 and the fixed rack and the movable rack are engaged with each other, and secondly, the sliding door is suspended from the slide rail. As a result, it was possible to reduce the vertical width of the interlocking device part to less than half of that of the conventional device, so that the interlocking sliding door with good appearance could be invented.

  An embodiment of the present invention will be described with reference to FIG.

  First, two slide rails (11) are attached in parallel to the upper frame (8) made of aluminum. Next, the joining member (12) is attached to the upper part of the sliding door 1 (1) and the sliding door 2 (2), respectively, and the joining member is attached to the slide rail and suspended. At this time, a pinion (6) into which a bearing is inserted is attached horizontally to the end of the upper surface of the sliding door 2, and a movable rack (5) meshing with the pinion is attached to the upper part of the sliding door 1. Further, a fixed rack (7) meshing with the pinion is attached to the upper frame. Finally, a fixed door (9) is attached to form an interlocking sliding door.

  As described above, the interlocking sliding door of the present invention is used as a sliding door having a wide entrance and exit, and is therefore used in a building or room.

The side view of this invention interlocking sliding door. The side view of the conventional interlocking sliding door. When the interlocking sliding door is closed, A is a plan view and B is a front view. When half of the interlocking sliding door is opened, A is a plan view and B is a front view. A is a plan view and B is a front view when an interlocking sliding door is opened. FIG. 4 is an explanatory diagram of an interlocking sliding door using a rack and pinion, where A is closed, B is half opened, and C is a plan view showing opened. In the rack and pinion mounting view of the present invention, A is a plan view and B is a side view. (A utility model literature 1) rack and pinion attachment drawing, A is a plan view, B is a side view.
