Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a retractable gate used for the frontage of a garage, etc.

(Problems to be Solved by the Invention) However, in the conventional structure described above, the geometric pattern composed of diagonal and vertical beams tends to be relatively monotonous and without accents. In view of this, various methods have recently been proposed to add accents and prevent monotony by incorporating auxiliary members, but this results in a complicated structure and is extremely difficult to assemble and manage parts. There was a problem that the process became complicated, and together with the increase in material costs, the cost became high.

(Means for Solving the Problems) The telescoping gate of the present invention is capable of opening and closing in the horizontal direction by pivoting a link mechanism consisting of a number of diagonal beams to a vertical beam. The mechanism consists of a first diagonal strut that goes down to the right and a second diagonal strut that goes up to the right, intersecting each other in an X-shape, and these cross the lower part of the first diagonal strut and the upper part of the second diagonal strut. A first link unit having a first slant and a second link unit in which an upper part of a first slant and a lower part of a second slant are cross-coupled are arranged alternately in the left and right direction, and in the link mechanism, an appropriate A main vertical beam is arranged at the bending part of the link, an auxiliary vertical beam is arranged at the link intersection part, and each end of the adjacent diagonal beam is pivoted so as to be freely bendable. It is said that

(Function) The telescoping gate of the present invention can obtain a varied geometric pattern and improve the sense of design by attaching each diagonal beam at a point other than the equal dividing point in at least one link mechanism. .
