Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a sliding door installed in a building opening, and in particular, a guide rail for guiding a shutter curtain up and down is provided on a vertical frame of the sliding door to simplify the mounting of the shutter device. It concerns the structure of sliding doors.

[0002]

[Prior art]

 Conventionally, when attaching a shutter device to an existing building opening equipped with a sliding door, a guide device is installed upright on both sides of the opening, and a shutter device in which a shutter curtain is housed above the opening is used. The arrangement is generally known. However, in this type, since the guide rail is attached to the inside of the opening frame part that constitutes the opening part, the opening width is inevitably narrowed, and the effective opening area decreases when the sliding door is opened. Not only that, but also during the installation work of the shutter device, the standing position of the guide rail must be erected without inducing interference between the shutter curtain and the sliding door, which is troublesome to adjust. It had a drawback that it would become a thing.

[0003]

[Problems to be solved by the present invention]

 The present invention has been made in view of the above circumstances in order to eliminate the conventional drawbacks, and the purpose thereof is to have an extremely simple structure, but to install a guide rail separately. The shutter device can be easily attached to the building opening, the installation of the shutter device can be simplified, and the open area of the existing opening can be effectively used while maintaining the crime prevention function. It aims to provide a sliding door structure.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the technical means adopted by the present invention is to form guide rails for vertically guiding a shutter curtain on a vertical frame of a sliding door installed at an opening of a building such as a window and a doorway. In addition, the shutter curtain can be moved up and down when the sliding door is fully closed.

[0005]

[Action]

 Therefore, according to the present invention, the shutter device can be easily attached without reducing the open area of the sliding door, and the security of the opening provided with the sliding door can be improved. it can.

[0006]

【Example】

 The configuration of the present invention will be described in detail with reference to one embodiment shown in the drawings. In FIG. 1, reference numerals 1 and 1 denote double-sliding sliding doors installed in a building opening 2. The sliding doors 1 and 1 have lighting windows 3 and 3 on top of door panels 1a and 1b, respectively. The sliding doors 1 and 4 are fitted together, and the pull tabs 4 and 4 are provided on the door end side, and the vertical rails 5 and 5 on the door end side are integrally provided with guide rails 6a and 6b having a U-shaped cross section. 1 is configured to come into contact with the vertical frames 2a, 2a of the opening 2 when the chain is closed.

On the other hand, a storage case 8 in which the shutter curtain 7 is wound and stored is horizontally provided above the opening 2 in the width direction of the opening, and the shutter curtain feeding port 8a has a shutter. Delivery guide portions 9, 9 are provided so as to transfer both ends of the curtain 7 to the guide rails 6a, 6b on the sliding doors 1, 1 side. In addition, 10 and 10 are running rails of the sliding doors 1 and 1.

When the sliding door 1 on the left side is pulled in the above-mentioned configuration, the door panel 1a moves on the traveling rail 10 in the direction of arrow A as shown in FIGS. 2 (a) and 2 (b). Suru At this time, the guide rail 6a attached to the door end side vertical frame 5 of the door panel 1a also moves in the same manner, and the opening 2 is opened. In this state, the open opening 2 has a wide open area between the vertical frames 2a and 2a as the guide rails 6a and 6b move together with the sliding doors 1 and 1, so that the opening 2 is limited. The part 2 can be effectively used.

When lowering the shutter curtain 7 to the opening 2, as shown in FIGS. 5A and 5B, first, the opening 2 is closed by the sliding doors 1 and 1, and the sliding doors are closed. The door end side vertical frames 1, 5 are brought into contact with the vertical frames 2a, 2a of the opening 2. Next, when an elevating switch (not shown) is operated to move down, the shutter curtain 7 moves between the shutter curtain feeding port 8a of the storage case 8 and the guide rails 9 and 9 between the guide rails 6a and 6b via the feeding guide portions 9 and 9. Then, the opening 2 is closed and the opening 2 is closed. By closing the opening 2 with the shutter curtain 7, the sliding doors 1 and 1 are kept in a locked state without separately providing a locking device. It becomes possible to do.

In addition, even when the shutter device is retrofitted to the existing opening 2, the storage case 8 accommodating the shutter curtain 7 is laid horizontally over the opening 2 to replace the conventional sliding door. By simply installing the sliding doors 1 and 1 of the present invention in the opening 2, it is possible to equip the shutter device without requiring a particularly large installation work. In addition, in this embodiment, the guide rails 6a and 6b are integrally provided on the door-end vertical frames 5 and 5 of the sliding doors 1 and 1, but the present invention is not limited to this, and the door tips are not limited thereto. Locking hooks are provided at predetermined intervals in the longitudinal direction of the side vertical frames 5 and 5, and guide holes 6a and 6b are provided with locking holes corresponding to the locking hooks. The rails 6a and 6b may be detachably mounted.

Next, FIG. 4 shows a structure in which the sliding doors 1 and 1 of the present invention are used in the bay window 10, and the bay window 10 has a shutter curtain 7 wound around the window opening 11. A storage case 8 that has been stored is provided, and a sliding door 1, 1 made of transparent glass formed in an arc-shaped cross section is mounted between the storage case 8 and the window frame 12 to form a bay window 10. ing. As shown in FIGS. 5 (a) and 5 (b), the sliding doors 1 and 1 are provided with guide rails 6a and 6b each having a U-shaped cross-section on the door side vertical sides 13 and 13, respectively. When the sliding doors 1 and 1 are closed, the guide rails 6a and 6b come into contact with the frame-side vertical frames 14 and 14 of the window opening 11 in the circumferential direction by pulling the sliding doors 1 and 1. Since the guide rails 6a and 6b move integrally with each other, the window opening 11 can be opened, and the limited opening area of the bay window 10 can be effectively used.

[0012]

[Effect of device]

 In short, the present invention forms guide rails for vertically guiding the shutter curtain on the vertical frames of the sliding doors installed in the openings of the building such as windows and doorways, and at the same time, Since the shutter curtain can be moved up and down when fully closed, the guide rail can be accurately installed without causing interference between the shutter curtain and the sliding door during the installation work of the shutter device. The installation of the shutter device can be simplified and the effective opening area of the sliding door can be used to the maximum, and the shutter curtain can be easily installed in the existing opening while maintaining the security function in the opening. It has a very useful practical effect that it can be retrofitted.
