Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gap adjustment device for adjusting the gap between a beam and a lateral movement stopper of a deck such as a work stage or a bridge.

(Prior art) In the past, this type of gap adjuster was
It is publicly known in No. 52280 etc.

This adjuster is made of hard synthetic resin material such as vinyl chloride or rubber.

Regarding the former, the latter is desirable since the cost of the mold is high, but vulcanization during molding takes time and poses a problem in mass production.

(Problems to be Solved by the Invention) The object of the present invention is to solve the above-mentioned conventional problems and to provide a deck gap adjustment tool that does not require much time for vulcanization and is excellent in mass production.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a block-shaped main body made of a rubber material and a reinforcing material built into the rubber material, and a block-shaped main body that protrudes from the front of the main body and has an outer circumferential surface. The present invention proposes a deck gap adjustment tool comprising a protrusion with a groove formed therein and a retaining ring that is easily attached to and detached from the protrusion groove of the protrusion.

(Function) The adjuster of the present invention has the structure described in the claims for utility model registration, and in particular, since the reinforcing material is built into the rubber material of the main body, vulcanization during molding does not take much time, making it easy to mass-produce. Are better.

The adjuster of the present invention has the same structure as above, and in particular, since the reinforcing material is built into the rubber material of the main body, the amount of rubber used can be reduced.

(Example) The deck gap adjuster of the present invention will be described below according to an example shown in the drawings.

FIG. 1 shows an example of a deck in which the gap adjuster of the present invention is used.

That is, the deck 3 has a gap between its lateral movement stopper 4 and the beam 1 as it is.

2 and 3 show an adjustment device 7, which has a block-shaped body 8. FIG.

A protrusion protrudes from the front surface of the main body 8, and the protrusion is a columnar body with a protrusion groove 14 formed on its outer peripheral surface.

In the illustrated embodiment, the projection head 15 is tapered distally.

Next, the main body 8 consists of a rubber material 8a and a reinforcing material 8b built into the rubber material 8a.

The reinforcing member 8b is made of, for example, a steel pipe, a steel rod, a wood rod, or the like.

The thickness of the rubber material 8a on the outer periphery of the reinforcing member 8b is made thin.

Next, a retaining ring 16 is provided which is attached to the protrusion groove portion 14.

The retaining ring 16 has a body 17 in which an elongated fitting hole 18 is provided.

A substantially V-shaped guide groove 20 that reaches the fitting hole 18 is provided at the tip of the main body 17 .

Next, in the illustrated embodiment, the thickness of the hem 19 at the tip of the main body 17 is tapered.

The retaining ring 16 is made of elastic hard synthetic resin.
Made of elastic hard material such as hard rubber.

The function of the deck gap adjuster of the present invention shown in the above embodiments is as follows.

That is, when manufacturing the main body 8 of the adjuster 7, the reinforcing material 8b is used therein, so the thickness of the rubber material 8a is thin.

Therefore, when the main body 8 is molded, the rubber material 8a is rapidly vulcanized starting from its surface.

As a result, the adjustment tool 7 can be vulcanized in a short time and can be mass-produced.

Next, a method of using the adjuster 7 manufactured as described above will be explained.

That is, the protrusion of the adjuster 7 is inserted into the hole 5 of the front lateral movement stopper 4 which places the deck 3 on the beam 1.

If the projection head 15 is tapered, insertion into the hole 5 is easy.

Next, attach the retaining ring 16 to the guide groove 2 at its tip.
0 to the protrusion groove portion 14.

Since the guide groove 20 at the tip is approximately V-shaped, it is widened and the protrusion groove 14 is fitted into the fitting hole 1 of the retaining ring 16.
8 as shown in FIG.

If the wall thickness of the head 19 is tapered, it will slide smoothly into the protrusion groove 14.

As a result, the adjuster 7 is installed in the gap between the lateral movement stopper 4 of the deck 3 and the beam 1, as shown in FIG.

Next, when removing the retaining ring 16, since the retaining ring 16 is a long hole, by hooking a bar material to the fitting hole 18 and pulling it, the fitting hole 18 will open naturally and be removed.

(Effects of the invention) The embodiments of the deck gap adjuster of the invention are as described above, and the effects thereof are listed below.

(1) The adjuster of the present invention has the structure described in the claims for utility model registration, and in particular, since the reinforcing material is built into the rubber material of the main body, vulcanization during molding does not take much time, making it easy to mass-produce. Are better.

(2) The adjuster of the present invention has the same structure as above, and in particular, the amount of rubber used can be reduced because the reinforcing material is built into the rubber material of the main body.
