2. Description of the Related Art Conventionally, as this kind of telescopic gate, FIG.
The following are known. The conventional telescopic gate shown in FIG. 8 includes a plurality of vertical bars (each having a pair of front and rear bars) 2, 2,. The gate body 1 is formed by connecting the right-downward oblique crosses 32, 32,... With telescopic links (upper and lower pairs) 3, 3 which are assembled in a pantograph shape, and the gate main body 1 is opened and closed in the left-right direction. I am getting it.

[0003] Further, in the conventional telescopic gate, each of the upper right-hand oblique crosspieces 31 and 31 and the right-downward oblique crosspieces 32 and 32.
For one vertical bar (having a pair of front and rear bars) 2, upper, middle, and lower sections are provided with intersections 21, 22, and 23, which intersect back and forth, respectively, while being adjacent to the left and right. It is assembled in a state where crossing portions 34 and 35 which cross each other in the upper and lower directions are provided between the two vertical bars 2 and 2 respectively. The telescopic link 3 and each of the vertical rails 2, 2,... Pivotally connect the middle intersection 22 to the vertical rail 2 with a fixed shaft 4 (indicated by a white circle) so as not to be vertically slidable. 21 and the lower intersection 23 with respect to the vertical rail 2
5 (indicated by black circles) guides vertically slidably.
Further, the upper crossing portion 34 and the lower crossing portion 35 located between the vertical bars 2 and 2 in the telescopic link 3 are pivotally connected with axes 6 and 6, respectively (in other conventional examples, the vertical bar 2 , 2 in which one of the upper intersection 34 and the lower intersection 35 is in the non-axial state).

[0004]

However, as in the conventional telescopic gate shown in FIG.
When the middle intersection 22 is pivotally mounted on the fixed shaft 4 so that it cannot slide up and down, the upper intersection 21 and the lower intersection 23 at the upper and lower positions are used to link the front and rear oblique beams 31 and 32. The shafts (in this case, sliding shafts) 5 and 5 need to be pivotally connected, and as a result, the shafts ( 4, 5, 5) is required, and there is a problem that the number of parts and the number of assembling steps increase (the cost increases).

In view of the above-mentioned problem of the conventional telescopic gate, the present invention intersects the upper right oblique crossing and the right lower oblique crossing of the telescopic link with the vertical cross at three places of upper, middle and lower. An object of the present invention is to simplify the assembly structure of the telescopic link and each of the vertical rails in the telescopic gate assembled as described above, so that the number of parts and the number of assembly steps can be reduced.

[0006]

According to the present invention, a plurality of vertical rails are connected by a telescopic link formed by assembling a plurality of upper right slant crossbars and a plurality of right lower slant crossbars in a pantograph shape. In the telescopic gate that can be opened and closed in the left-right direction, each of the upper right and lower right ramps has an intersection at each of three vertical, upper, middle and lower sections. On the other hand, it is assembled with two upper and lower intersections provided between two adjacent vertical rails, and one of the upper and lower intersections corresponding to the vertical rails is vertically aligned. The upper shaft and the lower cross corresponding to the vertical bar are pivotally attached to the vertical bar by the sliding shaft. It is pivoted freely, and the middle intersections corresponding to the other vertical rails except for the vertical rails at both ends are not pivoted. It is characterized in that the pivoted by a shaft at least one of the intersections of the intersections of the upper portion and the lower portion of the respective longitudinal 桟間 side.

[0007]

According to the telescopic gate of the present invention, one end of each of the upper right inclined crossbar and the right lower inclined crossbar of the telescopic link is vertically moved with respect to every other two adjacent vertical crossbars. Assemble in a state where the other is not slidable and the other is slidably linked up and down. Further, at least one of the upper and lower intersections intersecting between the vertical rails is pivotally attached to the shaft to assemble. When the telescopic gate is opened and closed, the upper right and lower right ramps pivot up and down about a fixed shaft that is pivotally attached to the vertical rail (sliding). The driving shaft slides up and down with respect to the vertical rail). Therefore, even when the middle crossing part corresponding to the vertical cross between the upper right diagonal cross and the right downward diagonal cross is set to the non-axial state, the telescopic gate can be opened and closed without any trouble.

[0008]

According to the telescopic gate of the present invention, by adopting the above configuration, even if the middle intersection of the telescopic link corresponding to the vertical bar is in the non-axial state, the gate does not obstruct. It can be opened and closed without any extension. Further, since the shaft is omitted at the middle intersection, the number of parts and the number of assembling steps can be reduced, and the production cost can be reduced.

Each of the upper and lower telescopic links 3, 3 is sequentially arranged in such a manner that a plurality of right-upward oblique bars 31, 31,... And a plurality of right-downward oblique bars 32, 32,. It is configured to be connected in the left-right direction. Each of the upper right-handed oblique beam 31 and each right-downwardly oblique beam 32 are connected to each vertical beam 2 at both ends.
While the intersections 21, 22, and 23 are provided at three places of the upper, middle, and lower tiers for each of the vertical beams 2, 2,.
It is assembled in a state where crossing portions 34 and 35 are provided at two upper and lower portions between two adjacent vertical rails 2 and 2.

In the first embodiment, each of the vertical rails 2,
2 and the upper and lower telescopic links 3, 3 are connected as follows. In each of the upper and lower telescopic links 3, 3, the lower intersection 23 located at a position corresponding to each vertical bar 2 is pivotally connected to the vertical bar 2 with the fixed shaft 4 so as not to slide vertically (see FIG. 5). The upper crossing portion 21 located at a position corresponding to the bar 2 is pivotally attached to the vertical bar 2 so as to be vertically slidable on the sliding shaft 5 (see FIG. 3).
Furthermore, the middle crossing portions 22 at the positions corresponding to the vertical rails 2 are in an unaxial state (see FIG. 4) in which they are simply crossed, and two upper and lower positions located between the adjacent vertical rails 2 are provided. Of the intersections, only the upper intersection 34 (the intersection near the sliding shaft 5) is pivotally connected with the shaft 6 (see FIG. 6). That is, the intersection (lower intersection) 23 between the lower end of the upper right oblique beam 31 and the lower end of the right downward oblique beam 32 in the telescopic link 3 cannot move vertically with respect to the vertical beam 2 with the fixed shaft 4. Pivoted,
The crossing portion (upper crossing portion) 21 of each upper end of each of the oblique bars 31 and 32 is located next to the vertical bar 2 pivotally connecting the lower ends of each of the oblique bars 31 and 32 to the right or left and is next to the next. The vertical shaft 2 is pivotally mounted on a sliding shaft 5 so as to be vertically slidable. Since the upper crossing portion 34 between the vertical bars 2, 2 is pivotally connected with the shaft 6, the vertical bars 2, 2, ... are linked so as to be able to expand and contract in the left-right direction.

As shown in FIG. 5, the fixed shaft 4 comprises two bars 12, 12 on the front and rear sides of the vertical bar 2, an upper right-hand oblique beam 31 and a right-downward oblique beam 3.

Are portions that cannot be slid up and down with respect to the vertical rail 2.

In the telescopic gate of the first embodiment, the middle crossing portion 22 of the telescopic link 3 corresponding to the vertical bar 2 is in the non-axial state, but the middle crossing portion 22 is in the non-axial state. However, the gate body 1 can be opened and closed without any trouble. Further, when the middle-stage crossing portion 22 is in the non-axial state, the number of parts and the number of assembling steps can be reduced accordingly.
In the first embodiment, the upper crossing portion 34 between the vertical rails 2 is pivotally connected with the shaft 6, but this pivoting portion is applied to the lower crossing portion 35 instead of the upper crossing portion. It is also possible,
In that case, a similar effect can be obtained. In another embodiment, both the upper and lower intersections 34 and 35 between the vertical rails 2 and 2 can be pivotally connected with the shaft 6 respectively. Further, in this embodiment, for the upper and lower telescopic links 3 and 3, the middle crossing portion 22 corresponding to the vertical rail 2 is in the non-axial state.
In another embodiment, the middle-stage intersection 22 can be set to the non-axial state only for one of the telescopic links 3.

In the telescopic gate according to the second embodiment shown in FIG. 7, the upper crossing portion 21 corresponding to the vertical crossbar 2 of the right upper crossbar 31 and the right lower crossbar 32 is opposite to the first embodiment. Is vertically and non-slidably mounted on the vertical rail 2 with the fixed shaft 4, while the lower crossing portion 23 corresponding to the vertical rail 2 is vertically slidably movable with the sliding shaft 5 with respect to the vertical rail 2. At the same time, the lower intersection 3 of the two intersections 34, 35 between the vertical beams 2, 2
Only 5 is pivoted on axis 6. Also, in the case of the second embodiment as well, the portion of the middle intersection 22 corresponding to the vertical rail 2 is in an axial state (just intersects). With the telescopic gate of the second embodiment, the same operation and effect as in the first embodiment can be achieved.
