Therefore, for example, a telescopic gate is constructed by rotatably connecting the front and rear diagonal beams and does not have a vertical beam, or even if it is equipped with a vertical beam, it may only be for decorative purposes or if it is not equipped with wheels. For telescoping gates, etc., which are located in inappropriate positions for installation, even if various previously known wheel mounting structures are applied as is, the diagonal beam will rotate as it expands and contracts. I had a problem with not being able to install it.

A plurality of front and rear diagonal beams each having a bent end at least on the lower side are rotatably connected at at least one intersection thereof, and
In order to solve the above-mentioned problems in a telescoping gate, the upper and lower ends of which are opposed to each other are rotatably connected, a telescoping door body is provided, and wheels are attached to this telescoping door body. As a means of the present invention, the wheel holder to which the wheel is attached is formed with a link engagement part and a fitting part separated above or below this, and the fitting part of the wheel holder is formed by: The wheel holder is rotatably fitted to arbitrary lower bent ends of the front and rear diagonal rails that are rotatably connected to face each other, and the wheel holder is installed across these lower bent ends; In addition, one end of two links of the steady rest mechanism consisting of four links provided in a substantially rhombic shape are respectively fixed to the lower bent end to which the wheel holder is attached, and each of these two links is One end of two other links is rotatably connected to the other end, and the other ends of the other two links are vertically movably engaged with the link engaging portion of the wheel holder. It is something.

When the telescoping door body of this telescoping gate is extended or contracted, the lower bent ends of the diagonal beams are rotated in opposite directions. However, since the wheel holder is rotatably fitted to these bent ends, the bent ends are allowed to rotate in opposite directions, allowing the telescopic door body to expand and contract. Does not interfere with operation. At the same time, the four links of the steady rest mechanism are linked by the rotation of the bent end, and the ends of two of the links are aligned along the link engagement part of the wheel holder. Move up and down. In this case, one rotatably connected upper and lower link and the other upper and lower link are rotated in opposite directions, so that the wheel holder receives forces in opposite directions from both sides thereof. Therefore, although the wheel holder can freely rotate relative to the bent end, the wheel holder itself cannot freely rotate around the bent end.
The wheel holder to which the wheels are attached will not fall, as this is prevented by the steady rest mechanism made up of the above-mentioned links.

Then, the front and rear diagonal beams at one end on the gatepost side are approximately 1/2 in length, and their tips are connected by a pivoting means, and this pivoting section is connected to the gatepost, fixed support, etc. In addition, in the above embodiment, the diagonal beam was formed into a substantially U-shape, but instead, a diagonal beam having a substantially L-shape with a bent end only at the lower end may be used. In this case, the upper opposing ends are connected via a pivot passing through them, as in the conventional case. Moreover, the link engaging portion of the wheel holder may be formed by a shaft, and a long hole extending in the vertical direction may be provided in the lower part of the lower link, and these may be slidably engaged. Further, contrary to the above embodiment, the upper link may rotate downward when the telescoping door body is extended, and the upper link may rotate upward when the telescoping door body is retracted. Further, in the present invention, the fitting part may be provided above and apart from the link engaging part, and in this case, the steady rest mechanism is of course provided upward, contrary to the above embodiment.
Furthermore, the present invention can be applied to a telescopic gate in which the intermediate portions of the front and rear diagonal beams intersect at multiple points.
