Description

[Detailed Description of the Invention] The present invention relates to the structure of a telescoping gate having a pantograph-type link mechanism.

Conventionally, pantograph-type telescopic gates have a pair of vertical bars 1 and 2 facing each other at a certain interval, and a plurality of vertical bars 1 and 2, as illustrated in FIGS. 1 and 2. A pair of connecting rods 3, 4 are arranged in pairs and are placed next to each other between the vertical bars A, A1, A2...
are spanned in a criss-cross pattern, and these intersections A are pivoted, and an auxiliary vertical beam 5 is attached to the pivot intersection A. And connecting rods 3 and 4
For the case, assemble the lower part B of one connecting rod 3 and attach it to the vertical bar A.
Pivotally attach it to the vertical bar 1 of 1, and attach the upper end C to the adjacent vertical bar A.
The other connecting rod 4 is slidably engaged in a groove 6 formed in the vertical bar 1 of the assembly A, and the other connecting rod 4 has its lower end 2 pivoted to the vertical bar 2 of the adjacent assembled vertical bar A, and its upper end H is It is slidably engaged in a groove 7 formed in the vertical bar 2 of the assembled vertical bar A1. The engagement of this connecting rod 4 with the vertical bars 1 and 2 is carried out by the support shaft 8.
This is carried out by rollers 9, 9 attached to the support shaft 8, and the upper end of a connecting rod 3a, which spans between the vertical assembly beams A1, A2, is fitted into the support shaft 8. or,
The lower end 2 of the connecting rod 3 is mounted on a support shaft that is stretched between the vertical bars 1 and 2, and the connecting rod 4 that is stretched between the assembled vertical bars A1 and A2 is attached to this support shaft.
The lower end of a is fitted.

In this way, the pair of connecting rods 3, 4... are successively spanned, and the upper ends of each connecting rod 3, 4... move up and down along the grooves of the vertical bars 1, 2 through the rollers. , the telescopic gate can be opened and closed.

Generally, the connecting rods 3, 4... of a telescopic gate based on this structure are as shown in Fig. 2.
When viewed from above, they are lined up in a straight line.

However, such connecting rods 3 arranged in a straight line,
If 4 is a simple slender rod, the entire gate can be reduced to a smaller size without interfering with each other, but if the connecting rods 3 and 4 are designed with consideration as shown in If the gates are wide, they interfere with each other when opening the gates, making it impossible to shorten them to a smaller size, making it difficult to open the doorway wide.

The purpose of this invention is to make the doorway wide open by contracting it to a small size even if a wide connecting rod is used in a telescoping gate with such a pantograph-type link mechanism. It is an elaborate version.

That is, in the present invention, a plurality of connecting rods extending between each set of vertical bars and tilting in the same direction are mutually shifted in the projected direction with respect to the adjacent connecting rods by at least a dimension corresponding to the wall thickness of the connecting rods. It is characterized by the fact that it is arranged in a planar staggered manner.

The illustrated embodiment will be described below. Third
In the figures and FIG. 5, one of the connecting rods 10, which is connected between the assembled vertical beams A and A1, is closer to the vertical beam 1, and has an insertion portion 13 at its upper end through which the support shaft 12 for attaching the roller 11 is inserted. The insertion portion 13 has a length that reaches the center line l of the telescopic gate. Further, a shaft insertion portion 15 that projects toward the auxiliary vertical beam 14 is integrally formed at the shaft attachment intersection portion A of the connecting rod 10. The lower end B of this connecting rod 10 is the assembled vertical bar A.
It is inserted into a support shaft (not shown) installed between each of the vertical bars 1 and 2 of 1, but its insertion part (not shown) is located at the center of the telescopic gate, similar to the insertion part 13 at the upper end. It has a length that reaches line l.

This connecting rod 10 is spanned in a state close to the vertical bars 1, 1 of the assembled vertical bars A, A1.

On the other hand, the connecting rod 10a adjacent to the connecting rod 10 is spanned between the assembled vertical bars A1 and A2, and the connecting rod 10a is connected to the upper end of the assembled vertical bar A1 that moves up and down along the vertical bars 1 and 2. has an insertion part 18 through which the mounting shaft 17 of the roller 16 is inserted,
This insertion part 18 is composed of a protruding part 18a facing the vertical beam 1 and a protruding part 18b reaching the center line l of the telescoping gate.

The lower end 4 of this connecting rod 10a is also provided with a shaft insertion portion made of a similar protrusion.

Since the protrusion 18a facing the vertical bar 1 has at least a dimension corresponding to the wall thickness of the connecting rod 10, the connecting rod 10a is separated from the vertical beam 1 by the above dimension with respect to the connecting rod 10. They are arranged in a staggered manner.

In this way, the connecting rods 10, 10a, . As a whole, they are arranged in a staggered pattern on a plane.

In addition, it is stretched between the assembled vertical bars A and A1, and the vertical bars 2,
A support shaft 17 that is inserted into the insertion portion 18 of the connecting rod 10a is attached to the upper end E of the connecting rod 19 located toward the 2nd side.
The insertion part 20 is composed of a protruding part 20a facing the vertical bar 2 and a protruding part 20b extending to the center line l, and the protruding part 20a has an insertion part 20 for inserting at least the connecting rod 19. , 19a... are formed with a length corresponding to the wall thickness. The lower end 2 of this connecting rod 19 also has an insertion part made of the same protrusion as the above-mentioned protrusions 20a and 20b.

That is, this connecting rod 19 has the same shape as the connecting rod 10a, and the connecting rod 19 has the same shape as the connecting rod 10a.
0a, it is spanned from the vertical bars 2, 2 by the above-mentioned dimension.

On the other hand, it is stretched between the vertical crosspieces A1 and A2,
The connecting rod 19a adjacent to the connecting rod 19 has an insertion portion 23 at its upper end that moves up and down along the vertical assembly A2, through which the mounting shaft 22 of the roller 21 is inserted. The lower end 23 has an insertion portion through which a fixed support shaft (not shown) is inserted, and each insertion portion 23 is formed with a length that reaches the center line l, and furthermore, A shaft insertion portion 24 that projects toward the auxiliary vertical beam 14a is provided at the shaft attachment intersection portion A of the connecting rod 19a.

That is, this connecting rod 19a is the aforementioned connecting rod 10.
It has the same shape as , and is spanned close to the vertical bars 2, 2. The connecting rods 19a are offset from the connecting rods 19 by the thickness of the connecting rods 19, 19a, and are arranged in a staggered manner.

In this way, the connecting rods 19, 19a... located on the other vertical beam 2 side of each set of vertical bars A, A1, A2... As a whole, they are arranged in a staggered pattern on a plane.

The above embodiment shows a case where the shape of the pair of connecting rods 10, 19 is different, but FIG. 4 shows an example where the shape of the pair of connecting rods 25, 26 is the same, and in this case , adjacent connecting rods 25,
In order to make the 25a, 26, and 26a staggered so as to have a staggered plane as a whole, spacers 27 having corresponding lengths are used.

As described above, in the present invention, adjacent connecting rods are arranged alternately in a staggered manner on the plane as a whole, so when the gate is opened as shown in Figure 6, each connecting rod is arranged in a staggered manner. There will be no collision,
Therefore, even if the width of the connecting rods is large, the connecting rods do not interfere with each other, and the gate can be made smaller by bringing the vertical bars of each set closer together.

In other words, if the contraction width is the same as that of a conventional telescoping gate equipped with a link device consisting of a slender rod, the link device will be designed with more consideration than the conventional rod. This makes it possible to provide a retractable gate with an excellent aesthetic appearance.
