Description

[Detailed explanation of the idea] The present invention relates to an improvement of a retractable gate.

Conventionally, this type of gate has wheels that run on rails, and in order to run on rails, the rails must be installed on the ground, which requires a lot of effort.

When the wheels of a retractable gate are run directly on the ground, the ground is made flat with cement, concrete, etc., and in many cases the cement, concrete, etc. slopes downward from the indoor side to the road side. The object of the present invention is to provide a telescoping gate that can be sufficiently adapted and run stably not only when the ground is horizontal but also when the ground has a slope.

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a telescoping gate, and the telescoping gate 1 includes a large number of diagonal bars 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, . A vertical bar 5 is vertically disposed on a selected pivot portion 4 of the interconnecting link mechanism 3, and a pair of front and rear wheels 6 are installed at the bottom of the selected vertical bar 5.
In this embodiment, in order to further stabilize the running of the wheels 6 and 7, two wheels are mounted at a distance in the direction of expansion and contraction of the link mechanism 3. The pair of front and rear wheels 6, 7 are arranged so that their mounting positions can be changed in the vertical direction with respect to the vertical beam 5, respectively.

In this embodiment, the pair of front and rear wheels 6, 7 are supported by support frames 8, 9, respectively, and their mounting positions can be changed in the vertical direction to mounting members 10 fixed to the lower part of the vertical beam 5, respectively.

In this embodiment, the bolts 11 protruding from the support frames 8 and 9 are connected to elongated holes 1 formed in the mounting member 10.
2 is inserted and tightened with the nut 13, the wheel 6,
7 can be independently changed in the mounting position within the range of the elongated hole 12 in the vertical direction with respect to the vertical beam 5.

One embodiment of the present invention is constructed as described above, but unless it goes against the gist of the present invention, the structure, shape, material of the link mechanism, vertical beam, wheel, means for mounting the wheel in the vertical direction, etc. are the same as in the above embodiment. It goes without saying that the invention is not limited and can be modified in various ways.

In this invention, a vertical bar is vertically arranged at a selected pivot point of a link mechanism formed by connecting a large number of diagonal bars that are arranged at inclinations in opposite directions. It is a telescoping gate equipped with a pair of wheels, and the front and rear wheels can be independently changed in their mounting positions in the vertical direction with respect to the vertical beam. When traveling on the ground, it can be fully adapted not only when the ground is horizontal, but also when it has a slope, by changing the mounting position of one of the front and rear wheels in the vertical direction, and only one wheel is required. It has various practical effects such as effectively preventing the telescopic gate from tilting due to contact with the ground and providing stable running.
