Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a sleeve that accommodates a pivot shaft that passes through a pivot portion of a diagonal beam of a telescoping gate.

BACKGROUND ART There is a telescopic gate door in which a plurality of vertical vertical bars are connected by intersecting diagonal bars so that the entire gate can be expanded and contracted in the horizontal direction.

In such a telescopic gate, a pivot shaft is attached to the pivot portion of the crossed diagonal bars by penetrating the two diagonal bars, but the diagonal bars may come into contact with each other or the pivot shaft may In order to prevent the diagonal beams from coming into contact with each other and causing unpleasant metallic sounds, the pivot shaft was housed inside a synthetic resin sleeve to prevent contact.

Problems to be solved by this invention When using the pivot shaft sleeve of such a telescoping gate as the pivot at the top end of the diagonal beam, the cap and sleeve that fit on the top end must be made separate, or the sleeve must be attached to the top end. Only the sleeve was used as a cap, and a separate member was used for the sleeve used in the middle. Therefore, manufacturing costs have been high due to the use of a large number of members.

Furthermore, with the conventional sleeve, when the telescoping gate is folded, it has not been possible to prevent the parallel diagonal bars from coming into contact with each other and causing a metallic sound.

Means for Solving the Problems The pivot shaft sleeve of the telescoping gate according to this invention is formed into a U-shaped cross section by a rectangular base plate and two clamping plates extending in parallel from the left and right ends of the base plate. However, a cylindrical insertion portion that penetrates through each other is provided on the back surface of the opposing side surfaces of the two holding plates.

By covering the end face of the diagonal beam with the substrate, it can be used as a sleeve that also serves as a cap.

Further, at the intermediate portion of the diagonal beams, the side surfaces of the diagonal beams are covered with a substrate to prevent the diagonal beams from coming into contact with each other.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, A denotes a sleeve according to this invention, which is made of synthetic resin such as vinyl chloride.

The sleeve A is formed into a U-shaped cross section by a rectangular substrate 1 and clamping plates 2, 2 extending in parallel from the left and right ends of the substrate 1. The width w ₁ between the clamping plates 2, 2 is approximately the same as the width w ₂ of the diagonal bar 4, which will be described later. Cylindrical insertion portions 3, 3 are respectively provided protrudingly provided on the back surfaces of opposite side surfaces of the clamping plates 2, 2, and the insertion portions 3, 3 penetrate through each other. The inner diameter of the insertion portions 3, 3 is approximately the same as the outer diameter of the pivot shaft 10, which will be described later.

Next, a telescopic gate assembled using the sleeve A having the above structure will be explained.

The diagonal bar 4 includes a long diagonal bar 4a and a short diagonal bar 4b, both of which are hollow members with a square cross section. Diagonal beam 4
A through-hole 5 is bored horizontally at the upper and lower ends or at the middle portion, which is to serve as a pivot point.

The sleeve A is attached to the diagonal beam 4 so that the through hole 5 and the insertion portions 3 communicate with each other. That is, the diagonal crosspiece 4 is attached so that its side surfaces are held in two pieces by the holding plates 2, 2. When the sleeve A is attached to the end of the diagonal bar 4, the end face of the diagonal bar 4 is covered by the substrate 1, and when it is attached to the middle part, the side surface is covered by the substrate 1.

By using the diagonal bar 4 as described above, a plurality of vertical bars 6
Concatenate. The vertical bar 6 consists of a hollow part 7 and a lip groove 8 formed on the side surface of the hollow part 7, and the two vertical bars 6, 6 are integrated with a predetermined distance apart so that the lip grooves 8, 8 face each other. ing. That is, the fitting portions of the connecting block 9 having fitting portions on the left and right lower surfaces are respectively fitted into the hollow portions 7 of the vertical bars 6, and the two vertical bars 6, 6 are integrated in parallel.

A plurality of vertical bars 6, 6 integrated in this way are connected using a long diagonal bar 4a and a short diagonal bar 4b. The diagonal bar 4 is the insertion part 3 of the sleeve A of the pivot part,
3, insert the pivot shaft 10 into the through hole 5 of the diagonal bar 4,
The two are rotatably crossed. Long diagonal beam 4a
The pivot shaft 10 in the intermediate part is fixed to the vertical bars 6, 6 by a pin 11 penetrating the hollow part 7, and the short diagonal bar 4
b, the upper end pivot shaft 10 is fixed. The pivot shafts 10 fitted in the lip grooves 8, 8 of the other vertical bars 6, 6 are housed in the sleeve A, and are able to slide within the lip grooves 8, 8. Long diagonal beam 4
The pivot shaft 10 of the pivot portion of the short diagonal bar 4b is prevented from detaching from the inside of the sleeve A by means of a split pin or the like.

As described above, the pivot shaft 10 fitted into the lip grooves 8, 8 of the diagonal bar 4 slides along the vertical bar, and supports the pivot parts of the long diagonal bar 4a and the short diagonal bar 4b. axis 10
moves up and down, the crossing angle of the diagonal bars 4, 4 changes,
The entire structure can be slid horizontally.

When the telescopic gate is folded, the board 1 of the sleeve A attached to the middle part of the diagonal bar 4 covers the side surface of the diagonal bar 4, so the sleeve A board 1 is attached to the side surface of the adjacent diagonal bar 4 that is parallel to it. There will be no unpleasant metallic noise or scratches caused by contact.

Effects of the invention This invention has the above-mentioned configuration, and is formed into a U-shaped cross section by a rectangular substrate and two clamping plates extending in parallel from the left and right ends of the substrate. Cylindrical insertion portions that penetrate through each other are provided on the back surfaces of the opposing sides of the clamping plates.

Therefore, since the end face of the diagonal beam can be covered by the substrate, it can be used as a sleeve that also serves as a cap, there is no need to increase the number of parts, and the telescopic gate can be manufactured at low cost.

If the sleeve is installed in the middle of the diagonal beam so that the board covers the side surface of the diagonal beam, the parallel diagonal beams will not come into contact with each other, which will prevent unpleasant metal noises and damage. There is no.
