Description

[Detailed Description of the Invention] The present invention relates to a telescoping gate having a diagonal rod.

In conventional telescoping gates, the diagonal rods are connected by bolts or rivets, but this can cause rattling in the diagonal rods, or rainwater can enter through the gaps between the bolts and cause rust. It had the following drawbacks.

Therefore, when bolting, etc., a method was used to fit a resin material into the through hole of the diagonal rod to prevent wobbling and gaps from occurring, but the resin material also rotated as the gate expanded and contracted. This caused the resin material to be cut at the cut end of the through hole, and there was a risk that rattling or gaps would occur after a short period of use.

In order to prevent this drawback, some systems have been found in which the through hole is made into a non-circular hole and the fitting resin material is shaped to fit the non-circular hole (Utility Model Application No. 52-69837). Compared to a simple circular hole shape, this required more work and was unavoidable due to its high cost.

The present invention has been devised in view of this point, and one embodiment of the present invention will be explained below with reference to the drawings. 1 and 1' are diagonal rods arranged front and back at appropriate intervals, and are opposite to each other. tilted at the same angle in the direction.

2 are through holes provided at opposite positions of the diagonal rods 1 and 1';3;
is a tube fitted into the through hole 2, and has a length that is half or less than the thickness of the diagonal rods 1, 1';
It has the shape of a wing piece 4 that hugs the outer wall surface of the wing.

In the drawing, the oblique rods 1 and 1' have an oval cross section, and the tip of the wing piece 4 is bent, but the shapes of the oblique rods 1 and 1' and the shape of the wing piece 4 are limited to those in the drawing. It is not something that will be done.

Reference numeral 5 denotes an intervening member such as a collar that maintains the distance between the diagonal rods 1 and 1', and is provided with an insertion hole 6.

7 is a shaft tube inserted into the hole of the tube body 3 and the insertion hole 6 of the inclusion 5, and 8 is a fastening member such as a blind rivet for fixing the shaft tube 7 and the outer wing piece 4.

Then, the tube body 3 is inserted into the through hole 2 of the diagonal rods 1, 1' from the front and rear sides, and the tube body 3 is inserted into the intervening rod with the wing pieces 4 holding the diagonal rods 1, 1'. The shaft tube 7 is inserted into the object 5, and the shaft tube 7 and the outer wing pieces 4 are fastened together at both ends by fastening members 8 to connect the diagonal rods 1 and 1'.

The present invention is constructed as described above, the through holes 2 of the diagonal rods 1, 1' may be circular holes, the work efficiency is high, and the tube body 3 holds the diagonal rods 1, 1'. Since the wing pieces 4 are provided, the tube body 3 fitted into the through hole 2 is connected to the oblique rods 1, 1'.
The tube body 3 is prevented from rotating due to the expansion and contraction operations, and therefore the tube body 3 can withstand use for a long period of time without fear of cutting wear etc., and there is no corrosion of the diagonal rods 1, 1' due to the occurrence of gaps. This not only makes it possible to more smoothly extend and retract the diagonal rods 1 and 1', but also simplifies the assembly structure of the extendable gate.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention, with Figure 1 being a front view and Figure 2 being a front view.
The figure is an exploded perspective view of the main part, and FIG. 3 is a cross-sectional view of the main part. 1 and 1' are oblique rods, 2 is a through hole, 3 is a tube body, 4 is a wing piece,
5 is an inclusion, 7 is a shaft tube, and 8 is a fixing member.
