Description

[Detailed description of the invention] [Industrial application field] The present invention relates to industrial vehicles such as forklifts that use LP gas as fuel, and more specifically relates to an improvement of an annular band for tightening cylinders constituting an LPG cylinder support device. .

[Prior Art] Several types of LPG cylinder support devices for industrial vehicles have already been proposed, and one of the devices that has been suitably implemented is a device having the structure shown in FIG. 2. This device uses the rear support of the head guard, and the cylinder holder 10 has a pair of left and right side plates 12a, 12b, and both side plates 12a, 12.
It consists of two support rods 14, 14 that connect b.
A hinge bracket 16 fixed to one side plate 12a is rotatably attached to a fixing bracket 20 provided on one rear column 18a of the head guard via a pivot shaft (not shown), and the hinge bracket 16 is attached to the other side plate 12.
The locking piece 22 extending from b is connected to the other rear strut 18.
It is configured to be locked to a fixing bracket 24 provided at b via a removable locking pin (not shown).

and installed on the cylinder holder 10.
A lower half ring 28b of an annular band 28 is provided on the cylinder holder 10 as a mounting and tightening means for the LPG cylinder 26, and an upper half ring 28a of the annular band 28 is expandable via a hinge member.
is fixed so that the hook 30 pivoted on the support rod 14 can be fitted into the expanded end of the upper half ring 28a, and the lower end of the cam piece 32 pivoted on the upper side of the hook 30 is fixed. , engages with the locking curved edge 28c extending at the expanded end and pushes it down, and the upper half ring 28
It is configured to tighten the LPG cylinder 26 by elastic deformation of a.

In order to stably tighten the cylinder, a cushioning material of a predetermined thickness made of rubber or flexible resin is glued to the inner circumference of the annular band, which is usually made of flat steel. It is attached by an agent.

[Problems to be solved by the invention] However, since the annular strap of the above-mentioned form is manufactured to match the outside diameter of the cylinder to be loaded, it is not possible to use cylinders of different sizes. In addition to this inconvenience, the above-mentioned cushioning material is easily peeled off by repeated attachment and detachment of the cylinder, and if a cylinder is attached without noticing that the cushioning material has peeled off, remove the slack equivalent to the thickness of the cushioning material. There is even a danger that the cylinder may fall off.

The technical problem to be solved by the present invention is to create an annular band that can easily accommodate the use of cylinders of different sizes and that does not cause problems such as peeling of the cushioning material.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a structure in which the lower half ring is fixed to a cylinder holder supported on the vehicle body, and the paired upper half ring is expandable via a hinge member. The annular band has a cross-sectional shape in which the center part is bent toward the outer circumference, leaving both side edges, and the annular band is removably fitted to the both side edges. A new structure is adopted in which the elastic band is covered with an elastic band that has a holding part and an adjustment buffer part that bulges at the center of the inner circumference.

[Function] Therefore, the annular band is significantly strengthened due to the cross-sectional shape in which the central portion is bent and protruded toward the outer circumference, and the elastic body covered with the annular band has the elastic opening of the holding portion. It can be easily attached to and detached from both side edges of the annular band using the legs, and it can also be easily adapted to cylinders of different diameters by selecting the thickness of the adjustment buffer section bulging at the center of the inner circumferential side.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. Note that parts that are the same as those of the conventional device are given the same reference numerals, and some of the illustrations are omitted.

FIG. 1 is a partially cutaway perspective view of the annular band 280, in which the annular band 280 is attached to the cylinder holder 10.
It consists of a lower half ring 280b fixed by welding or the like on the two support rods 14 constituting the structure, and an upper half ring 280a deployably connected to the lower half ring 280b via a hinge member 29, which will be described later. A cylinder (not shown) is held between these half rings 280a and 280b. The above circular band 280
has a cross-sectional shape in which the center part is bent and protrudes outward 280e leaving both side edges 280d, and the lower half ring 280b has a receiving metal fitting 29a constituting the hinge member 29 at the connecting end of the lower half ring 280b, and an upper half ring 280a. The collars 29b are fixed to the joint ends by welding or the like, and the upper half ring 280a can be expanded about the hinge pin 29c co-inserted therewith. The locking curved edge 28
A lip portion (not shown) is provided for mating with optional cylinder fastening means such as c. Almost the entire area of the upper half ring 280a and the lower half ring 280b, excluding the hinge member 29 portion and the edge portion engaging with the cylinder tightening means, is covered with an elastic band 40, respectively.

The elastic band 40 has holding portions 40a formed in opposing U-shapes that fit with the both side edges 280d of the annular band 280, and an adjustment portion 40a that bulges out at the center of the inner circumferential side of the annular band 280 in the covered state. A buffer section 40b is provided. The elastic band 40 is molded using rubber or flexible resin, and its flexibility is such that it can be attached to and detached from both side edges 280d of the annular band 280 due to the artificial elastic legs of the holding portion 40a. It is made to the extent that it can be fitted. The annular band 280 is adjusted so that it can hold the maximum diameter of the applicable cylinder when the adjustable buffer portion 40b is covered with the elastic band 40 made to have the minimum thickness. Therefore, when a cylinder with a somewhat smaller diameter is to be loaded on board, the existing elastic band 40 is removed and the thickness of the adjustment buffer part 40b is increased in advance by the difference in radius between the large and small cylinders. By covering the elastic band 40 with the elastic band 40, the cylinder support device including the annular band 280 can be easily adapted to the use of cylinders of different diameters.

[Effects of the invention] As explained in detail above, since the present invention has the configuration described in the claims for utility model registration, there is no risk of the elastic band falling off unless it is destroyed, and By simply replacing and removing elastic bands with different thicknesses from the adjustment buffer part prepared in advance, it is possible to easily accommodate the use of cylinders of different diameters on board, and in particular, it is possible to unify the annular band into one type. It exhibits an excellent ability to help streamline production and eliminate assembly errors. Furthermore, since the center portion of the annular strap has a cross-sectional shape that bends and protrudes, the strength of the annular strap is dramatically improved, and this effect is hard to overlook in terms of ensuring safety.
