In the closed condition of the respective doors adjacent in the direction of site inside and outside, the door bodies are successively moved so as to be the inside or the outside of the site, and also one holding frame 1b of the door A1 out of the doors being adjacent to each other in the open/close direction is positioned in the middle of the two holding frames 1c, 1d of the door A2 on the other side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking gate, that is, when one door travels to open and close, the other doors sequentially connected also interlock to travel and open and close.

[0001]

2. Description of the Related Art A conventional interlocking gate will be described with reference to FIGS. 8 is a perspective view showing the doors that make up the interlocking gate in a separated state, FIG. 9 is a perspective view of the doors connected to each other, and FIG. 10 is a front view of the interlocking gate being open.
Similarly, it is the side view seen from the front end side.

A conventional interlocking gate is composed of one leading door A to which a force is applied when opening and closing, and one or a plurality of succeeding doors B connected to the leading door. The wheels 6 attached to the lower end of the holding frame 1 framed in the shape of a rectangular door are placed on rails 7 laid on the road surface and run along the rails.

More specifically, the leading door A is the door body 2
A is supported and fixed in the front and rear gate-shaped holding frames 1a and 1b at the site outside portion of the holding frame, and the door body 2A and the holding frame 1
An accommodation space 3 for accommodating the door body 2B of the subsequent door B is formed in the site inside of the a and 1b. The leading door A can stand up and run independently by itself, whereas the trailing door B has the door body 2B only at the rear holding frame 1c and is located closer to the inside of the site than the leading door body 2A. In the front position of the door main body 2B, the rollers 4B projecting from the upper and lower sides of the door main body 2B are guided to the upper and lower frames 5A of the door main body 2A of the leading door A on the inside surface of the site. The leading door A is movably supported by being rotatably fitted in the groove.

As shown in FIG. 10, when the other subsequent doors C to E are to be added, the frames 5B above and below the door body 2B of the subsequent door B existing outside the site of the additional door to be added are also added. ,
A guide groove formed on the inner surface of the site is provided so that the roller attached to the front portion of the door body of the subsequent door to be added can be rotatably fitted. 10 and 11 are a front view and a side view in a fully opened state of a 5-link interlocking gate having four subsequent doors B to E, respectively.

[0005]

Since the conventional interlocking gate has the above-mentioned structure, in the leading door, the load of the door main body is evenly divided by the front and rear holding frames and the load is applied. In the door, half of the load is applied to the front roller shaft, so especially when the gate length is long, the roller shaft is not horizontal and smooth rotation of the roller is hindered. There is a problem in that the interlocking gate cannot be opened and closed smoothly only by pulling out or pushing in. Further, in the fully opened state of the interlocking gate, as illustrated in FIG. 10, since the loads of the front portions of all the subsequent doors are applied to the holding frame of the leading door, it is necessary to increase the strength of the holding frame of the leading door. It is also necessary to increase the connection strength between the door body and each holding frame. Therefore, there is also a problem that the holding frame becomes large. Further, the leading door and the trailing door have different structures and have a master-slave relationship, and it is necessary to install the leading door so that it is always located at the beginning of the closing direction of the interlocking gate, and the trailing door is used as the leading door. Is impossible. Therefore, there is no construction convenience, and it is not possible to arbitrarily determine the opening / closing direction of the interlocking gate.

The present invention has been made in view of the problems of the conventional interlocking gates described above, and solves the problem of unsmoothness of opening and closing due to the unbalanced load of each door main body, and the holding frame has a minimum necessary amount. It is an object of the present invention to provide an interlocking gate in which the size of the interlocking gate can be arbitrarily determined, the master-slave relationship between the doors can be eliminated, and construction can be easily performed, and the opening / closing direction of the interlocking gate can be arbitrarily determined.

[0007]

In order to achieve the above object, the interlocking gate according to the present invention is composed of a plurality of doors all having substantially the same structure. That is, the door body is supported and fixed in a holding frame that is framed in a rectangular shape before and after the door body, and wheels that roll along rails are provided at the lower end portions of all the holding frames. Each of the doors that are adjacent to each other in the inward / outward direction has the door body sequentially displaced toward the inside or outside of the premises, and one holding frame of one of the doors that are adjacent to each other in the opening / closing direction is one of the two doors of the other door. It is characterized by being located in the middle of one holding frame.

[0008] Preferably, a pair of rollers for sandwiching and guiding the upper frame of the door main body of the door of the next rank is provided on the upper part of the rear holding frame of the door of the preceding rank in the direction of closing the gate.

[0009]

Next, an embodiment of the present invention will be described. As shown in FIG. 1, the interlocking gate according to the present invention is formed by connecting a plurality of doors A1 and A2 having substantially the same structure in a predetermined intersecting state. Each door A1, A2
Are the front and rear rectangular holding frames 1a, 1b; 1c, 1 respectively.
The front and rear ends of the door bodies 2a and 2b are supported and fixed in d. In the closed state, the door bodies 2a and 2b of the doors A1 and A2 that are adjacent to each other in the in-site and out-of-site directions are sequentially displaced in the out-of-site direction or the in-site direction. At the upper part of the rear holding frame (1b in the example of FIG. 1) of the first order door (A1 in the example of FIG. 1) in the gate closing direction, the next order door (A in the example of FIG. 1)
It is provided with a pair of rollers 4r for nipping and guiding the upper portion of the door body 2b of 2), the upper frame 5b in the illustrated example.

With the above structure, the load of each door is dispersed and supported by the front and rear holding frames of the respective doors, and the respective holding frames stand up independently and one holding frame is located before and after the adjacent doors. The wheels 6 attached to the lower ends of the respective holding frames can travel and move within a range in which they can move. Therefore, when the holding frame (1a in the example of FIG. 1) of the leading door (A1 in the example of FIG. 1) is moved in the closing direction (left direction in the example of FIG. 1) or the opening direction, the following door (in the example of FIG. 1) A2) are sequentially interlocked and closed or opened. In the case where a pair of rollers 4r for sandwiching and guiding the upper frame 5b of the door body 2b of the next-order door is provided on the upper portion of the rear holding frame of the first-order door in the gate closing direction, the upper portions of the respective doors are connected together. The individual fall of each door due to strong wind is prevented, and the stability of the entire interlocking gate is improved.

[0011]

Embodiments of the present invention will now be described with reference to the drawings starting from FIG. 1 is a perspective view showing an example of a double-type interlocking gate, FIG. 2 is a vertical sectional view between the holding frames 1b and 1b of FIG. 1, FIG. 3 is a front view in an open state, and FIG. 4 is the same plan view.
5 is a side view of the same, FIG. 6 is a side view of a closed state, and FIG. 7 is a plan view of the same.

FIG. 1 shows two doors A which form an interlocking gate.
1, A2 are shown. Both doors have almost the same structure. That is, the door A1 on the left side of FIG. 1 has front and rear holding frames 1a and 1b and a door body 2a. Also,
The door A2 on the right side includes front and rear holding frames 1c and 1d and a door body 2
b.

Each of the holding frames 1a to 1d has the same structure as the holding frame in the conventional interlocking gate, and the upper frame 11 and both vertical frames 12 and 13 on the outside of the site are connected in a U-shape. A rectangular holding frame is configured by connecting the lower end of the to the lower frame 14. The wheels 6 attached to both ends of the lower frame 14 are rotatably mounted on rails 7 laid parallel to the road surface. The point to be noted is that the front holding frame 1c of the other door A2 is provided between the front and rear holding frames 1a and 1b of the one door A1.
Is the point where the two doors intersect.

Door bodies 2a and 2b in the respective doors A1 and A2
Are held inside the front and rear holding frames 1a, 1b; 1c, 1d, and are fixed to the upper frame 11 and the lower frame 14 of the holding frame using brackets 15 on the upper and lower frames of the door body.
The bracket 15 is connected to the holding frame and the door body by a bolt nut 16. FIG. 2 shows a state in which one door is mounted on the upper frame of the door body.

The difference between the two doors A1 and A2 is that
This is the position where the door body is attached to the holding frame. That is, in one of the doors A1, the mounting position of the door body 2a is set to a position closer to the outside of the site in the holding frames 1a and 1b, and the vertical frame inside the site of the door body 2a and the holding frames 1a and 1b is set. 12
While the accommodation space 3 capable of accommodating the door body 2b of the other door A2 is formed between the above and the other door A2, the mounting position of the door body 2b in the other door A2 is the door body in the one door A1. The door main body 2b and the door main body 2a are movably installed in parallel with each other closer to the inside of the site than the mounting position of 2a.

Further, at least a pair of abutting portions on the lower surface of the upper frame 11 of the rear holding frame 1b of the one door A1 are in contact with the inside surface and the outside surface of the site of the upper frame 5b of the door body of the other door A2. The roller 4r is rotatably supported around the shaft 17. In this way, when the two doors A1 and A2 are relatively moved along the rail, it is effective that the upper frame of the other door shakes due to the action of the pair of rollers and the upper frame of the door main body sandwiched by the rollers. To be prevented. Therefore, the smooth running of each door is maintained. Further, since the adjacent doors are supported by the rollers, it is possible to effectively prevent them from falling due to strong wind or the like.

The double-type interlocking gate shown in FIG. 1 is one door A1.
Is used as the leading door, so on the vertical frame 18 of the door A1,
A lock 19 to be locked is attached to a lock receiving portion (not shown) attached to a corresponding position of the gate pole. The vertical frame 1 of the door body 2a having the lock 19 when locked in the closed position
Since 8 must approach the gate pillar to the maximum, the attachment position of the door body to the holding frame in the door that is the leading door is, as shown in FIG. 11, the side closest to the gate pillar 20, that is, the holding frame 1a. It is desirable to be close to the vertical frame 13 outside the site or the vertical frame 12 inside the site. In FIGS. 4 and 7, reference numerals 21 and 22 are gate fences.

As described above, in the case of the double-type interlocking gate, a pair of rollers 4r may be attached to the upper frame 11 of the holding frame of one door A1, and the door body 2 of the other door A2.
It is not necessary to provide a storage space between b and the vertical frame 12 on the inside of the site, but in the case of a triple-type interlocking gate, it is between the main body of the holding frame of the first door and the vertical frame on the inside of the site. Is the second and the third
A storage space for storing the door bodies of the second two doors is formed, and the door body of the third door is stored between the door frame of the holding frame of the second door and the vertical frame inside the site. A possible storage space is formed.

The front holding frame of the third gate is arranged between the rear holding frame of the first gate and the second holding frame of the first gate, and is provided on the upper frame of the rear holding frame of the first door. A pair of rollers for the number of doors after the first door, that is, two pairs of rollers are attached. Further, a pair of rollers for guiding and sandwiching the door body of the third door is also attached to the second rear holding frame.

In the above embodiment, the first door A1 is installed as a leading door, and by moving to the left in FIG. 1, the succeeding doors A2 after the next order are interlocked to close the interlocking gate door and the reverse door. By displacing the leading door A1 to the right, the arrangement relationship of the holding frames of the respective doors is set so that the trailing door A2 is interlocked and the interlocking gate is opened.

As shown typically in FIGS. 4 and 7, in the interlocking gate according to the present invention, all the doors have basically the same structure, and the arrangement relationship of the holding frame of each door with respect to the other doors. Can be easily changed. Thus, for example, FIG.
The positional relationship between the front and rear holding frames 1a and 1b of the first door A1 and the second door A2, and the rear holding frame 1d of the second door A2 is changed to the front and rear holding frames of the first door A1. 1
Between the b and 1a, and the front holding frame 1d of the second door A2
If the leading door A1 is arranged on the outer left side, it is possible to obtain an interlocking gate that is opened when the leading door A1 is moved leftward and is closed when the leading door A1 is moved rightward. As described above, according to the interlocking gate according to the present embodiment, the same constituent members are used to change the positional relationship between the inside and outside of the site with respect to the holding frame of the door body and the crossing position relationship of the holding frames, so that the door can be opened and closed freely. Can be arbitrarily determined.

[0021]

As described above, according to the present invention, since the door body of each door is supported by the front and rear holding frames and can stand up and run independently, the load imbalance of the door body is unbalanced. The problem of smooth opening and closing due to the burden does not occur, and the holding frame can be of the minimum necessary size, and cost can be reduced.
Further, since the doors have substantially the same configuration, there is no master-slave relationship between the doors, and construction convenience can be obtained. Further, by changing the positional relationship between the inside and outside of the site with respect to the holding frame of the door body and the crossing positional relationship of the holding frames, it is possible to arbitrarily determine the left / right hand opening / closing.

When the upper frame of the door main body of the next-order door is guided by the guide roller attached to the upper frame of the rear holding frame with respect to the gate closing direction, unlike the conventional interlocking gate, the gate main body is different. Since it is not necessary to provide guide grooves in the upper and lower frames, the manufacturing is easy, the cost can be reduced, and the interlocking gate can be prevented from falling.
