DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved telescopic gate having a two-row pantograph mechanism.

[0002]

2. Description of the Related Art Conventionally, there is a telescopic gate installed at an entrance of a garage or the like, which is provided with two rows of pantograph mechanisms vertically. The pantograph mechanism employs link mechanisms of various shapes and structures, and by appropriately selecting the link mechanism, various types of extendable doors are provided.

In this kind of telescopic gate, if the upper and lower pantograph mechanisms interfere with each other at the time of the telescopic operation, the telescopic mechanism cannot be expanded or contracted. Therefore, conventionally, in both the extended state and the contracted state of the gate body, both the pantograph mechanisms are enlarged vertically so that the upper pantograph mechanism and the lower pantograph mechanism are always separated vertically. They are spaced apart.

[0004]

In a conventional telescopic gate,
Since the upper and lower pantograph mechanisms are always arranged vertically apart, the minimum length of the vertical frame material will be regulated by the vertical distance between each pantograph mechanism,
It is difficult to shorten the length of the vertical frame material.

That is, since it is necessary to secure a predetermined interval between each pantograph mechanism, in order to shorten the length of the vertical frame member, the length of each link member constituting each pantograph mechanism must be reduced. No. However, if the vertical frame members are shortened, the interval between the vertical frame members becomes narrower, and the number of link members and vertical frame members increases for a certain width, resulting in an extremely large number of parts. Will be. The present invention has been made in view of such conventional problems, and can reduce the length of the vertical frame material,
An object of the present invention is to provide a telescopic gate that can greatly reduce the number of parts.

[0006]

According to the present invention, both end frames 7, 7 are provided.
8 A plurality of vertical frame members 9 and 10 arranged between them are expanded and contracted by two upper and lower rows of pantograph mechanisms 11 and 12 which connect a plurality of link members 11a, 11b, 12a and 12b in a crossed manner. In a freely connected telescopic gate, a pair of adjacent link members 11a,
One pantograph mechanism connecting 11b, 12a, 12b in a chevron
11 and 12 and a pair of adjacent link members 11a and
The other pantograph mechanism that connects 11b, 12a, 12b in a valley shape
The two pantograph mechanisms 11 and 12 are provided so that the valleys 28 and 27 of the pantograph mechanisms 12 and 11 correspond to the top and bottom, respectively. The two pantograph mechanisms 11 and 12 are arranged close to each other vertically so as to fit into the valleys 28 and 27 of the eleventh and eleventh.

[0007]

According to the present invention, a pair of adjacent link members 11 is provided.
a, 11b, 12a, and 12b are connected in a chevron, and the crests 25 and 26 of one of the pantograph mechanisms 11 and 12 and a pair of adjacent link members 11
a, 11b, 12a, and 12b are connected to form a valley, and the two pantograph mechanisms 11, 12 are provided so that the valleys 28, 27 of the other pantograph mechanism 12, 11 correspond to the up and down directions. The two pantograph mechanisms 11, 12 are arranged close to each other so that the peaks 25, 26 of the pantograph mechanisms 11, 12 fit into the valleys 28, 27 of the other pantograph mechanism 12, 11, The vertical spacing between the pantograph mechanisms 11, 12 is reduced, and the length of each of the vertical frame members 9, 10 can be made shorter.

Further, since the distance between the pantograph mechanisms 11 and 12 is reduced, the length of each of the link members 11a, 11b, 12a and 12b constituting the pantograph mechanisms 11 and 12 can be increased. Therefore, since the interval between the pair of adjacent vertical frame members 9 and 10 can be made wider, even if the number of the vertical frame members 9 and 10 is reduced, the entire length of the entire gate can be sufficiently secured and the vertical frame members 9 and 10 can be secured. , 10 and link members 11a, 11b, 12a, 12b can be reduced, so that the manufacturing cost can be reduced by reducing the number of parts.

On the other hand, the lower pantograph mechanism 12 is also constructed in substantially the same manner as the upper pantograph mechanism 11, intersects each short vertical frame member 10 at one point, and each long vertical frame member 9.
A large number of the inner link members 12a and the outer link members 12b are respectively arranged obliquely in the diagonal direction so as to intersect at two places in the vertical direction, and are sequentially arranged in an intersecting manner, and the respective link members 12a, 12b Are provided inside and outside of the vertical U-shaped vertical frame members 9 and 10, respectively.

The lower pivot 22 of the upper and lower two pivots 22 corresponding to the long vertical frame member 9 has both ends fixedly connected to the long vertical frame member 9, and the upper pivot 22 has both ends of the long vertical frame member 9. 9 is slidable up and down and is irremovably supported. In addition, both ends of the pivot 23 corresponding to the short vertical frame member 10 are fixedly connected to the short vertical frame member 10.

Each of the vertical frame members 9 and 10 is formed of a C channel material whose inside is open. In addition, each axis 20, 21,
22, 23, the vertical frame members 9, 10 and the link members 11
Spacers are respectively inserted between a, 11b, 12a, and 12b.

Each of the pantograph mechanisms 11 and 12 has a pair of ridges 25 and 26 for connecting a pair of adjacent link members 11a, 11b, 12a and 12b into a ridge projecting up and down, and between the ridges 25 and 26. The valleys 27, 28 of the upper pantograph mechanism 11 and the ridges 26 and valleys 28 of the lower pantograph mechanism 12 are located on the left and right sides, respectively. The direction is shifted by a half pitch in the direction.

The two pantograph mechanisms 11, 12
When the gate body 4 is contracted to the minimum length, the upper ends of the vertical frame members 9 and 10 are configured to be substantially at the same height as shown in FIG. The peaks 25, 26 of one of the pantograph mechanisms 11, 12 are fitted to the valleys 28, 27 of the other pantograph mechanism 12, respectively, and approached in the vertical direction so as to overlap left and right by a predetermined length L. It is arranged in the state where it was.

That is, when the gate body 4 is contracted, the lower crest 25 of the upper pantograph mechanism 11 is located on the upper valley 28 of the lower pantograph mechanism 12 and the upper pantograph mechanism 12 is located on the upper side of the lower pantograph mechanism 12. The peaks 26 fit into the lower valleys 27 on the lower side of the pantograph mechanism 11 on the upper side, respectively.
1, 22 are arranged to enter the pantograph mechanisms 11, 12 at substantially the same height and upside down.

The telescopic gate of this embodiment is configured as described above, and if the handle 14 of the door stop side end frame 8 is gripped and operated in the telescopic direction, the gate body 4 expands and contracts, and the entrance 5
Can be opened and closed. Then, when the gate body 4 is contracted to the minimum length, as shown by phantom lines A and B in FIG.
It can be turned around 13.

In the extended state in which the gate body 4 is extended to the maximum length, the pantograph mechanisms 11 and 12 are vertically separated from each other. The fall in the front-rear direction can be reliably prevented, and the rigidity of the gate body 4 in the front-rear direction can be secured.

When the gate body 4 is contracted, the door stop side end frame 8 is moved to the hanging column 2 side, and in the upper pantograph mechanism 11, the pivot 20 of the long vertical frame member 9 and the short vertical frame member 10 are moved. Since the upper pivot 21 is fixed, the link members 11a and 11b intersecting at the pivot 20 rotate around the pivot 20 so as to push up the short vertical frame members 10 on both sides. At this time, the lower pivot 21 of the short vertical frame member 10 slides downward along the short vertical frame member 10.

On the other hand, in the lower pantograph mechanism, since the lower pivot 22 of the long vertical frame member 9 and the pivot 23 of the short vertical frame member 10 are fixed, each link member 12a, 12b is pivoted about the pivot 22. Rotate so as to push up the short vertical frame members 10 on both sides. At this time, the upper pivot 22 of the long vertical frame member 9 slides upward along the long vertical frame member 9.

Accordingly, as the gate body 4 is contracted, the lower crest 25 of the upper pantograph mechanism 11 is moved along the short vertical frame member 10 into the upper valley 28 of the lower pantograph mechanism 12.
The upper ridge 26 of the lower pantograph mechanism 12 moves along the long vertical frame member 9 to the upper valley 27 side of the lower pantograph mechanism 11.

When the gate body 4 contracts to the minimum length, as shown in FIG. 1, the vertical frame members 9 and 10 come into contact with each other, and one of the pantograph mechanisms 11 and 12 becomes one of the pantograph mechanisms 11 and 12. 12 peaks 25 and 26 are the other pantograph mechanism
Fits in the valleys 28,27 of 12,11.

As described above, when the gate body 4 is in the contracted state, the upper and lower ridges 25 and 26 on the corresponding sides of the two pantograph mechanisms 11 and 12 are fitted to the other valleys 28 and 27 so that the two pantograph mechanisms 11 and 12 fit together. Since the two rows of pantograph mechanisms 11 and 12 are arranged close to each other in the vertical direction, the distance between the two pantograph mechanisms 11 and 12 should be reduced despite the two rows of pantograph mechanisms 11 and 12. Can be. Therefore, regulation of the minimum length of each of the vertical frame members 9 and 10 can be relaxed, and the length of the vertical frame members 9 and 10 can be made shorter than before.

If the link members 11a, 11b, 12a and 12b constituting the pantograph mechanisms 11 and 12 are long, the distance between the pair of adjacent vertical frame members 9 and 10 can be increased, so that the gate Even if the number of vertical frame members 9 and 10 in the entire body 4 is reduced,
The same overall length as before can be secured. Therefore, vertical frame material 9,
Number of ten, number of each link member 11a, 11b, 12a, 12b, pivot
The number of components such as 20, 21, 22, and 23 can be greatly reduced, and the reduction in the number of components can greatly reduce manufacturing costs.

Moreover, since the peaks 25, 26 and the valleys 27, 28 on the corresponding sides of the respective pantograph mechanisms 11, 12 are shifted by a half pitch, one of the peaks of both pantograph mechanisms 11, 12 is shifted.
Despite the fact that 25, 26 fits into the other valleys 28, 27, the ridges 25, 26 on the corresponding side do not interfere with each other, and the gate body 4 smoothly expands and contracts. Can be done.
