Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a telescoping gate suitable as an exterior fence for a garage entrance or the like.

(Prior art) A plurality of horizontal link members are arranged in the left and right direction so that the upper and lower parts intersect in an X-shape. The telescopic gate, which has a horizontal link member pivoted by inserting a pipe-shaped vertical beam into the position, was developed in 1973.
It is widely known as disclosed in Japanese Patent Publication No. 44363, Japanese Patent Publication No. 57-43716, etc.

In this type of telescopic gate, the horizontal link member and the pipe-shaped vertical frame are fixed or rotatably fixed,
Insert a threaded shaft into the vertical frame and screw it in, or
The horizontal link member is fixed by fitting the horizontal link member into the pipe-shaped vertical bar and expanding the pipe from the inside of the vertical bar.

(Problem to be solved by the invention) However, when the horizontal link member and the vertical frame are fixed with screws, when the door body is repeatedly opened and closed, the screw part becomes loose and there is considerable wobbling. On the other hand, when expanding the vertical crosspiece from the inside and attaching the horizontal link, it is necessary to accurately position the pressurizing part of the vertical crosspiece, and the assembly work is extremely complicated, which is not suitable for mass production.

(Means for Solving the Problem) This proposal is to arrange multiple horizontal link members in the left and right direction that intersect in the shape of an In a telescopic gate door in which a horizontal link member is pivotally supported by inserting a pipe-shaped vertical beam into the intersection position of the end of the link member,
The horizontal link member is constituted by a bearing having a protruding piece on the side and a hollow horizontal crosspiece having an engagement groove into which the protruding piece fits, and the protruding piece of the bearing is fitted to the end of the horizontal crosspiece, The intended purpose was achieved by caulking and integrating the two.

(Example) In the drawing, a plurality of horizontal link members 1, 1... which are crossed in an X-shape at the upper and lower parts are arranged in the left and right direction, and the central intersection of the upper and lower horizontal link members 1, 1 is A pipe-shaped vertical beam 2 is inserted into the intersection of the ends of adjacent horizontal link members 1, 1, a bush 3 is interposed between the upper and lower horizontal link members 1, 1, and a pipe is attached to the top of the vertical beam. A horizontal link member is rotatably supported by an end protection cap 4, and the horizontal link member is a hollow shaft having bearings 6, 6 having projecting pieces 5 on the sides and an engaging groove 7 into which the projecting pieces fit. The horizontal bars 8 are combined, and the projecting piece 5 of the bearing 6 is fitted to the end of the horizontal bar 8 and integrally caulked to form the horizontal link members 1, 1...
, and one horizontal link member 1, 1 located in the same direction at the upper and lower parts is integrated with the vertical bar 2 by fixing the vertical bar 2 and the bearing 6 with a set screw. It is something.

In carrying out the present invention, the bearing 6 having the projecting piece 5 is formed by cutting an aluminum profile into pieces, and a hollow shape having convex engagement grooves 7, 7 on the upper and lower parts, which is made by aluminum molding, is used. The horizontal bar 8 is fitted into the protruding piece 5 of the bearing 6, and the engaging grooves 7, 7 of the protruding piece 5 and the horizontal bar 8 are fitted.
The overlapping position may be plastically deformed using a press machine. Moreover, at this time, if necessary, a notch can be provided in advance in the protruding piece 5 at the pressing position to make the fit between the two firm.

The telescoping gate shown in the figure has horizontal link members 1, 1 pivoted at their center intersection points using a pin shaft, and this center intersection point is attached to a pipe-shaped vertical beam that passes through the upper and lower horizontal link members. Therefore, in case of pivoting, a bearing with two protrusions symmetrically provided on the vertical crosspiece is used, one on the vertical crosspiece at the side end and one on the central vertical crosspiece. A horizontal beam may be constructed between them, and both ends of the horizontal beam may be caulked.

(Function) The telescoping gate according to the present invention has a bearing 6 having a protrusion 5 on the side.
and a hollow horizontal bar 8 having engaging grooves 7, 7 into which the protruding pieces fit, and fitting the protruding piece 5 of the bearing 6 into the end of the horizontal bar 8, so that the engaging groove and the protruding piece overlap. The bearings 6, 6 of the horizontal link members 1, 1... are formed by caulking the horizontal link members 1, 1...
By inserting ... into the pipe-shaped vertical bars 2, 2... and positioning the horizontal link members 1, 1... and the vertical bars 2, 2..., the main parts of the door body can be assembled extremely easily. Since the horizontal link member 1 and the vertical bar 2 are in contact with the bearing 6 and the vertical bar over a considerable distance in the vertical direction, the door body can operate extremely smoothly without rattling.

(Effects of the invention) According to the present invention, when fixing the horizontal link member 1 to the pipe-shaped vertical beam 2, there is no need to use fastening fittings such as through bolts, and it is possible to expand the vertical beam from the inside. Since the main part of the door body can be assembled simply by caulking without requiring complicated processes, productivity can be significantly increased.
