The present invention relates to a telescoping gate having a freely formed telescoping door body.

This invention is a telescoping gate that has a simple structure and can increase its rigidity, and can also be extended and contracted without vertical movement of the vertical frame, while also reducing costs. Our goal is to provide the following.

An embodiment of the present invention shown in the drawings will be described below.

In the figure, 1 is a gate post on the hanging side whose lower end is buried in the ground A, and one end of a telescopic door body 2 is attached and supported to the hanging side gate post 1 via a mounting mechanism 3. This is a telescoping gate according to an embodiment.

The telescopic door body 2 includes a plurality of link mechanisms 4, 4 provided spaced apart from each other in the vertical direction, and a large number of vertical bars that are connected by the link mechanisms 4, 4 and move toward and away from each other. 5... and 6, 7.

In addition, in this invention, the vertical beam 6 is not necessarily necessary,
This may be omitted and the hanging side gatepost 1 may also be used as the vertical beam 6.

Further, in the present invention, the plurality of link mechanisms 4, 4 are arranged in a vertically symmetrical pattern in this embodiment, but the arrangement is not limited to this, and as shown in FIG.

At these intersections, the diagonal columns are pivotally connected to each other so as to be freely rotatable.

In this embodiment, as shown in FIG. 6, these pivot joints are formed by providing a fixture 15 on a metal connecting shaft 14 that passes through a synthetic resin intervening material 13 between each diagonal pillar. be.

In addition, in the figure, 16 is a synthetic resin cap, 17 is a door wheel such as a caster attached to the lower end of an optional vertical beam 5, 7, as necessary, to support the extendable door body 2 and to extend and retract it. It is used to make it more stable.

Furthermore, all members other than those specifically designated as materials in the above description are made of extruded materials such as iron, aluminum alloy, or synthetic resin.

Although this embodiment has been constructed as described above, the implementation of the present invention is not limited to one embodiment of the present invention, and vertical bars, guide portions, diagonal pillars, and The specific structure, shape, position, etc. of the link mechanism, the pivot connection part between the diagonal columns, the pivot fixing part between the diagonal column and the vertical beam, and the sliding structure between the upper and lower ends of the diagonal column and the vertical beam are as follows. Of course, the present invention can be implemented with various configurations, and can also be implemented on double-swing type telescoping gates and telescoping gates with a multiple link mechanism structure in which a plurality of link mechanisms are arranged so as to overlap in the thickness direction of the telescoping door body. Needless to say.

The present invention described above has the following advantages because it has the configuration described in the claims of the above-mentioned utility model registration.

In an extendable door body having a plurality of link mechanisms spaced apart from each other in the vertical direction, the diagonal pillars of the link mechanisms are arranged across only three adjacent vertical bars, excluding the end diagonal pillars, and intersect with the vertical bars. Either one of the central portion of the diagonal column and the inclined upper and lower ends of the diagonal column is slidably engaged with the guide part, and the other of the inclined upper and lower ends of the diagonal column is rotatably pivoted to the vertical beam. By fixing it, the central part of the diagonal pillar tilts in one direction on the vertical beam,
It is possible to restrain three locations, the sloping upper end and the sloping lower end of two adjacent slanted pillars that are slanted in the other direction.

At the same time, the diagonal columns tilted in opposite directions are pivotally connected only between the vertical bars.

Therefore, with this restraining structure of the slanted pillars, the external force can be distributed to the three adjacent vertical bars, and by connecting the slanted pillars to each other, it is distributed over the entire telescopic door body via the link mechanism, and also by multiple link mechanisms. As a result, the rigidity of the telescoping door body can be significantly increased to prevent twisting, and stable telescoping operation can be achieved.

During the expansion/contraction operation, either the central part or the inclined upper and lower ends of the diagonal column slides in the vertical direction along the guide part of the vertical beam, and the other of the inclined upper and lower ends of the diagonal column is attached to the vertical beam. Since the telescopic door body can be extended and contracted by being fixedly fixed to the door body, the vertical beam does not move up and down during the telescopic operation, despite having a plurality of link mechanisms.

Furthermore, each of the diagonal columns of the link mechanism crosses each other at only one place between the vertical bars and is pivotally connected, and each of these pivotally connected portions is arranged along the expansion and contraction direction, so that unlike the conventional method, Unlike a structure in which the link mechanism has a rhombus shape continuous in the lateral direction, the number of pivot connections between the diagonal pillars can be reduced, and the number of diagonal pillars used can be reduced by not forming a continuous rhombus shape.

Therefore, the structure is simple and can be easily assembled, and the weight can be reduced.Moreover, due to the reduction in assembly cost, it can be manufactured at low cost and has high feasibility.
