Description

[Detailed Description of the Invention] Large telescopic gates used for wide entrances and exits in factories, etc. are formed wide to prevent them from collapsing due to wind pressure, etc., so cross-chain rods are required to serve as tension rods. The shaft round pipes at the upper and lower ends need to be thick round pipes that do not deform, but if thin cross-chain rods are used for aesthetic reasons, the shafts must be thin round pipes. By connecting and integrating a strong pipe rod between the round pipes on the shaft of the cross chain rod, it is reinforced and prevented from deforming the shaft pipes, and the cross chain rod operates smoothly to open and close the telescopic gate. The purpose is to make it better.

The details will be explained below with reference to the drawings. A long rod is bent at approximately the center to form a vertical rod and a curved rod, and the curved rod is formed to have an inclination of a required angle up to the center.
Frame rods 1 whose lower portions from the center portion are parallel to the vertical rods are arranged in parallel, and X-shaped intersecting chain rods 2 and 3 are opposed to the wide-spaced portions at the lower portions of the vertical rods and the curved rods.
In order to operate, the upper and lower ends of the X-shaped cross chain rods 2 and 3 are supported by thin upper and lower round pipes 4 and 5, one end of each of the round pipes 4 and 5 is expanded and a synthetic resin 6 is attached, The other ends of the round pipes 4, 5 are fitted into a cover member 9 having a flange 11 in the opening, and this cover member 9 is connected to the frame rod 1.
One end is press-fitted via the synthetic resin 6 into both the left and right openings of the connecting rod 7 of the thick pipe, respectively, and an enlarged diameter protrusion 10 is provided oppositely in the center of the round pipes 4 and 5 to form the flange 11. Cross chain rods 2 and 3 are mounted between the connecting rod 7 and the expanded diameter projection 10, and between the left and right ends of the connecting rod 7 and the expanded diameter projection 10.

Since the present invention is constructed as described above, the round pipes 4 and 5 that pivot the ends of the cross-linked rods 2 and 3 are connected by a strong pipe connecting rod 7, which is connected to the straight rod of the frame rod 1. Frame rod 1 because it becomes a strong tension rod with curved rod
will not be distorted or deformed by external pressure. Therefore, since the opening and closing operations of the cross-chain rods 2 and 3 are made smooth, the expansion and contraction of the gate can be improved. or,
Shaft round pipes 4, 5 at the upper and lower ends of the crossed chain rods 2, 3
The opposing connecting ends of the pipe are expanded to form a stop edge, and a synthetic resin 6 is attached to this, and both ends of the connecting rod 7 of the pipe are press-fitted, so the connection can be made robust without using rivets at that part. You won't be able to leave because of it. Also,
The other ends of the round pipes 4 and 5 are fitted into a cover member 9 having a flange 11 in the opening.
Since the round pipes 4 and 5 are connected to the frame rod 1, the cover member 9 prevents the other ends of the round pipes 4 and 5 from being damaged. Furthermore, since the enlarged diameter protrusions 10 are disposed opposite to each other at the central portions of the round pipes 4 and 5, the structure is simple and manufacturing is easy. Then, diameter-expanding protrusions 10 are provided oppositely in the central portions of the round pipes 4 and 5, and the flange 11 and diameter-expanding protrusions 1
0 and both the left and right mouths of the connecting rod 7 and the enlarged diameter protrusion 1
Since the cross-linked rods 2 and 3 are mounted on the round pipes 4 and 5, the cross-linked rods 2 and 3 can be easily mounted on the round pipes 4 and 5, and their positions can be maintained correctly. Therefore, the connection work can be done easily and quickly, and labor can be saved. In addition, the cross-chain rods 2 and 3 can be made of thin materials due to the connection of the connecting rod 7, and the round shaft pipes 4 and 5 can also be made of thin round pipes, making them lightweight, easy to handle, and aesthetically pleasing. It is an invention.
