Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mooring device for a chain for preventing a cylinder from falling.

[0002]

2. Description of the Related Art In order to prevent gas cylinders, etc., from falling over, it has been conventionally practiced to surround them with a chain. At this time, since the cylinder is usually installed with the immovable portion such as a wall of the building as a back, a mooring tool for mooring the chain is fixedly arranged on the wall portions diagonally rearward of both sides of the cylinder. And, as this mooring tool, L
A screw member having a mooring portion that is bent in a shape, a semi-annular shape, or a substantially annular shape is used.

[0003]

However, the L-shaped or semi-annular type has a drawback that the ring constituting the chain is easily hooked, but is easily detached. That is, when the cylinder leans due to an earthquake or the like and the weight of the cylinder is added to the chain, the chain is immediately disengaged, and the cylinder eventually falls. Further, when the mooring portion is bent in a substantially annular shape, it is less likely to come off than the L-shaped or semi-annular shape, but on the other hand, there is a problem that it is difficult to hook the ring constituting the chain. That is, since the chain cannot be hooked once it is bent in an annular shape, the chain must be hooked and then bent in an annular shape.

The present invention has been made in order to solve the above problems, and provides a mooring tool for a cylinder fall prevention chain which has a shape that is easy to catch the ring constituting the cylinder fall prevention chain and which is hard to come off. With the goal.

[0005]

In order to achieve the above object, a mooring tool for a cylinder fall prevention chain according to the present invention is a mooring tool for a cylinder fall prevention chain that is arranged so as to surround the cylinder. A mounting plate portion for fixing to the portion, and a mooring plate portion projecting forward substantially perpendicularly to the mounting plate portion, wherein the mooring plate portion has a predetermined distance from the outer peripheral edge when viewed from one surface of the mooring plate portion. In order to insert the mooring groove formed with and the ring forming the chain into the mooring groove, an inlet is formed at a position near the mounting plate portion on the outer peripheral edge of the mooring plate portion, and an outlet is formed in the mooring groove. It has an insertion path facing it, and the mooring groove is formed in a shape with deep groove parts that bite in the direction of the mounting plate on both sides of the exit of the insertion path, and the insertion path is curved with a predetermined width from the entrance to the exit. Notched to form an insertion path And anchoring plate portion Earl is formed near the entrance of at least the front side edge of the edge that is characterized by having a.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the embodiments shown in the drawings. 1 to 3 show an embodiment of the present invention, in which 1 denotes a mooring tool of this embodiment, which is provided with a mounting plate portion 2 and a mooring plate portion 3.

The mounting plate 2 is an arbitrary immovable part, usually a cylinder (not shown) is installed with the wall of a building or the like as the back, and therefore the present embodiment is mounted on the wall behind this cylinder. It is provided to fix the mooring tool. The shape is not particularly limited as long as it can perform such a function,
In this embodiment, it is formed in a substantially rectangular shape. Note that 2a, 2
Reference numeral b is an insertion hole for a bolt or screw (not shown) for attaching and fixing to the immovable portion.

The mooring plate portion 3 is provided so as to protrude substantially perpendicularly to the mounting plate portion 2, that is, in the direction opposite to the immovable portion to which the mounting plate portion 2 is fixed. The projecting position may be near the central portion of the mounting plate portion 2, but it is easier to manufacture the mounting plate portion 2 and the mooring plate portion 3 integrally, and the strength is excellent. Therefore, the metal plate material forming the mounting plate portion 2 and the mooring plate portion 3 is bent from the middle, that is, is protruded forward from the side edge of the mounting plate portion 2.

The mooring plate portion 3 is viewed from one side, that is, from the side surface in the direction of arrow X in FIG. 1 (corresponding to FIG. 2),
A mooring groove 31 having a predetermined size is formed at a predetermined distance from the outer peripheral edge 33. The insertion path 32 for inserting the chain into the mooring groove 31 has an outer peripheral edge 33.
2 is cut out at a position near the mounting plate portion 2 at a predetermined width, and this portion is used as an inlet 32a so as to bend downward while facing downward in FIG. 2 so that the outlet 32b faces the mooring groove 31. Has been formed. The width of this insertion path 32 is formed to be wider than the diameter of the rod-shaped or linear member that constitutes each ring of the chain, in order to insert the ring of the chain. It is preferable that the diameter is slightly wider than the diameter of the rod-shaped or linear member forming the ring. Further, among the edges of the mooring plate portion 3 forming the insertion path 32, a radius 33a on the front side near the inlet 32a is formed to facilitate insertion of the chain ring.

Further, the mooring groove 31 is formed in a generally elliptical shape as a whole, and is diagonally upward or diagonally downward toward both sides of the outlet 32b of the insertion path 32 in FIG. Two deep groove portions 31a and 31b formed so as to bite into are provided. Conversely speaking, the deep groove portions 31a and 31b cause the edge of the insertion path 32 forming the outlet 32a to project toward the mooring groove 31. With this structure, the mooring groove 31
Even if the ring of the chain inserted in the above is attempted to be removed through the insertion path 32, it will be caught by the deep groove portions 31a and 31b, so that it can be easily prevented from being removed.

In the present embodiment, the bulging portion 31c is formed by slightly bulging the inner edge of the mooring plate portion 3 forming the mooring groove 31, the edge substantially facing the outlet 32b. This is because shallow groove portions 31d and 31e are formed on both sides of the bulging portion 31c so that the chain ring engages with the shallow groove portions 31d and 31e.

The mooring tools 1 of this embodiment are usually used as a set of two, and are attached to an immovable part such as a wall part on the rear side of both sides of the cylinder. When installing, first attach the mounting plate 2
A bolt is inserted through the insertion holes 2a and 2b and fixed to the immovable portion. Next, as shown in FIG. 3, the ring 41 forming the chain 4 is passed through the insertion path 32 formed in the mooring plate portion 3. At this time, as shown by an imaginary line in FIG. 3, since a radius is formed on the front edge 33a near the entrance 32a,
Easy to insert. The ring 41 passes through the insertion path 32 and exits the exit 32.
It penetrates into the mooring groove 31 from b. After being inserted into the mooring groove 31, the chain 4 is pulled in the arrow Y direction shown in FIG. 3, and the ring 41 engages with the shallow groove portion 31e below the bulging portion 31c of the inner edge forming the mooring groove 31. To do. on the other hand,
Even if the chain 4 loosens for some reason and the ring 41 tries to move in the direction opposite to the Y direction, it is caught in the deep groove portion 31a or 31b and is not easily separated.

In the case of a gas cylinder or the like, a gas discharge preventer (not shown) is provided which operates a valve in response to shaking or falling of the cylinder due to an earthquake or the like to shut off gas discharge. There are cases. Therefore, a chain (not shown) is separately attached to the member that controls the operation of the valve of this type of gas release preventer, and this chain is also engaged with the mooring plate portion 3 together with the chain 4 described above. May be. Like the chain 4, the separate chain is usually arranged so as to be slightly pulled in the direction of the arrow Y in FIG. 3, so that it engages with the other shallow groove portion 31d. When the cylinder falls down, one end of this separate chain is attached to the mooring tool 1 of this embodiment, so the member controlling the operation of the valve attached to the other end is the gas release preventer body. The valve closes and the valve closes.

FIGS. 4 and 5 show a mooring tool 5 according to another embodiment of the present invention, and like the above-mentioned embodiment, the mooring plate having the mounting plate portion 6, the mooring groove 71 and the insertion path 72. Part 7
And is configured. It should be noted that, except that the mounting plate portion 7 is formed in a substantially semi-annular shape instead of a substantially rectangular shape, and the shape of the mooring groove 71 is slightly different, it has the same configuration and function as those of the above-described embodiments.
