Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate device.

[0002]

2. Description of the Related Art Conventionally, in a gate device used at a large entrance in a large-scale facility such as a factory, a school, a hospital, or the like, the length of a single gate body is relatively long in order to open and close a plurality of compound gates. Because of the length and the necessity of laying a dedicated rail for each gate, a storage space of the same length as the effective opening of all gates was required, and the burden of construction costs was large.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a device for opening and closing a plurality of gates, which can reduce the storage space for all the gates by half. .

[0004]

SUMMARY OF THE INVENTION According to the present invention, a single gate is housed inside a single main gate which moves a pair of rails installed at a predetermined place, and the single main gate is housed in the rail and the main gate alone. This is a gate device configured to move rails provided on left and right inner portions.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, when a sliding door-shaped main door that has been moved separately on the left and right sides when the large doorway is opened is moved when the doorway is closed, From the left fence on the front of the figure, the other main gate door moves the door wheel inward via the rail and stops at point A, and one main gate single unit from the right fence rails the door wheel. , And stops at point B, then pulls out the single-gate that has moved along the rail by its own door wheel in the state of being housed inside. Then, the door wheel at the rear end moves on the rail inside the main gate, and the door wheel at the front end moves on the rail at the threshold, and stops at the point A of the other main gate. (See Fig. 3)

[0006] Withdrawal movement of the single child gate is performed by first moving the single child gate from the inside of one main gate from the right wall.
It may be handled such that the child gate is pulled out to the point, the child gate alone moves continuously to pull the parent gate alone, and stops at the point A.

As a result, the entire triple door is used and the entire large entrance is closed.
(See Fig. 4)

When the entrance is opened, the operation opposite to the above-mentioned operation may be performed, so that even a triple-type gate can be smoothly opened.

The operation is the same even if the left and right main gates are all single-gate doors in a quadruple type in which the sub-gates are housed.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a sill section provided with a suitable width in a lateral direction of a predetermined place, and a pair of rails 2 and 2 are installed at an appropriate interval on this sill section.

Reference numeral 3 denotes a main gate unit having a total length of, for example, 4900 mm. The main gate unit has upper and lower frame members 4 and 4, vertical frame members 4 'and 4' and upper frame members 5 and 4 on both front and rear sides thereof. 5 is constituted.

6 is the front horizontal frame 4 of the main gate unit 3
And an inner rail 7 of a channel steel to be described later with an appropriate distance therebetween.

Reference numerals 7 and 7 denote inner rails made of channel steel connected between the lower ends of the vertical frame members 4 ', 4', 4 'and 4' on both front and rear sides of the main gate unit 3. The inwardly facing channel steel becomes a rail on which the door rollers 14, 14 of the child gate unit 10 described later move.

8, 8 are inner rails 7, 7 of the main gate unit 3;
The door wheel is provided on brackets 9, 9 installed at the lower end of the door, and the door wheel moves right and left in contact with the rails 2, 2 of the sill 1.

Reference numeral 10 denotes a single gate unit which is installed in the main gate unit 3 so as to be freely inserted into and removed from the main gate unit 3. The length of the single gate unit is, for example, 4600 mm.

The child door unit 10 has upper and lower frame members 11 and 11, vertical frame members 11 'and 11', and upper frame members 12 and 12 between the upper and lower frame members on both front and rear sides.

Reference numeral 13 denotes a fence rod provided at an appropriate interval between the front horizontal frame 11 of the gate unit 10 and the inner rail 7 of the channel steel.

Reference numerals 14 and 14 are attached to outer portions of base portions 17 and 17 provided between both lower end portions of the vertical frame members 11 ', 11', 11 'and 11' on both front and rear sides of the gate unit 10. The door wheel provided on the provided brackets 15, 15 is adapted to move right and left in contact with the inner rails 7, 7 of the main gate unit 3.

Doors 20, 20 are provided below the left and right projecting ends 19, 19 of the front base 18 provided between the front ends of the bases 17, 17 on the left and right sides. The door wheels 20, 20 move on the rails 2, 2.

The left and right protruding ends 19 of the front base 18 of the door unit 10 serve as stoppers for the outer ends of the main door unit 3 of the door unit 10 to be stored.

Reference numeral 16 denotes another main gate unit which is installed at a position opposite to the one main gate unit 3 (left side in FIG. 4). The structure of the other main gate unit 16 is the one main gate unit. The structure is the same as that of the single unit 3. The length of the other main gate unit 16 is, for example, 4900 mm as in the case of the one main gate unit 3.

Even in the case of the other main gate unit 16, a structure in which the other main gate unit can be housed and installed inside the main gate unit 16 can be provided, whereby a four-gate system can be configured. .

Reference numeral a denotes a fence on both left and right sides of the entrance. When the entrance is opened, each of the gates is entirely located inside the fence. The gate unit 10 is stored.

[0024]

As described above, the present invention is a gate device having such a structure, so that even in a facility having a large entrance / exit, the storage space for the gate can be greatly reduced and the operation of the gate can be extremely reduced. It can be easily and quickly, and the equipment is of a concisely structured structure, so that the overall construction cost can be relatively low,
The effect as a gate device in a large entrance where a plurality of long sliding doors must be prepared and installed is extremely large.
