JPH08324487A - Connecting structure of chain net of pneumatic fender - Google Patents

Abstract

PURPOSE: To provide an inexpensive connecting structure of a chain net of a pneumatic fender, not using any end link, and for preventing a hull or a fender main body from being damaged. CONSTITUTION: In each shackle 11, both terminal parts (a) are twisted by 90 deg. in relation to the bent tip side of the shackle 11, and a shackle pin 12 is inserted through it. Each shackle pin 12 is arranged in the direction perpendicularly intersecting the direction of the bent tip side of the shackle 11. Accordingly, when the shackle 11 is fitted to the ring member 5 and connected to an axial chain 2 and a circumferential chain 3 through the shackle pin 12, the shackle pin 12 is made to be approximately parallel to the side surface of a tire 4, namely, be parallel to the outer front surface of a fender main body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a chain net of a pneumatic fender, and more particularly to an improvement in the shape of a shackle that connects a ring member to an axial chain and a circumferential chain. is there.

[0002]

2. Description of the Related Art Conventionally, as a chain net of a pneumatic fender, as shown in FIG.
When the plurality of axial chains 2 arranged in the axial direction of the fender body 1 and the plurality of circumferential chains 3 arranged in the circumferential direction are arranged, the axial chain 2 and the circumferential chain 3
The old tire 4 is interposed at the intersection X with and the axial chain 2 and the circumferential chain 3 are connected to each other through the ring member 5 and the end link 6 as shown in FIG. The shackle 7 having a character shape is connected horizontally by a shackle pin 8.

That is, when the shackle 7 is directly connected to the ring member 5, the shackle 7 is in a so-called standing state with respect to the surface of the fender body 1, and the protruding portion of the shackle pin 8 attached to the end portion of the shackle 7 is removed. When it comes in contact with the hull and peels off the paint of the hull or scratches it, and when the shackle pin 8 is attached with the protruding part facing downward,
There is a problem that the surface of the fender body 1 is damaged.

For this reason, conventionally, an end link 6 is further interposed between the shackle 7 and the ring member 5 so that the shackle 7 becomes horizontal and the shackle pin 8 damages the hull and the fender body 1. I try not to.

[0005]

However, the connection structure in which the end link 6 is interposed has a problem in that the number of parts is increased and the processing and man-hours are required, resulting in an increase in cost. In order to solve such a problem, a so-called submerged shackle in which the tip portion of the shackle pin 8 is submerged in the shackle 7 has been proposed, but it is wider than the chain and expensive. However, it is not practical.

The present invention has been devised in view of the above conventional problems, and does not use an end link or the like, and is an air-type fender that is inexpensive and does not damage the hull or the fender body. It is an object of the present invention to provide a connecting structure for a material chain net.

[0007]

In order to achieve the above object, the present invention has a plurality of axial chains arranged in the axial direction of the fender body and a plurality of circumferential chains arranged in the circumferential direction. A connecting structure for a chain net of a pneumatic fender, which is connected to a crossing portion with a chain via a ring member and a shackle, respectively, wherein the shackle connects the ring member to an axial chain and a circumferential chain. The gist is that the shackle pin is twisted so as to be parallel to the surface of the fender body. The shackle is constructed by twisting about 90 degrees.

[0008]

The present invention is constructed as described above and twists the shape of the shackle connecting the ring member and each chain so that the shackle pin is parallel to the surface of the fender body, that is, about By twisting 90 degrees, the shackle pin can be connected without damaging the hull or the fender body without using the conventional end links, etc. Therefore, the number of parts is also reduced. In addition to being able to reduce the number, the processing and man-hours are also small, and the cost can be reduced.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is an overall perspective view of a shackle 11 embodying the present invention, and FIG. 2 is a front view in which a ring member 5 is connected to an axial chain 2 and a circumferential chain 3 by using the shackle 11. The shackle pin 12 is inserted by twisting both ends 11a and 11b of the shackle 11 about 90 degrees with respect to the curved front end side 11A.

The shackle pin 12 is the shackle 1
1 is arranged in a direction orthogonal to the direction of the curved distal end side 11A, and as shown in FIG.
When 1 is fitted into the ring member 5 and connected to the axial chain 2 and the circumferential chain 3 via the shackle pin 12, the shackle pin 12 is substantially parallel to the side surface of the tire 4, that is, the fender body 1 Is parallel to the outer surface 1a.

As a result, the terminal portion of the shackle pin 12 does not damage the hull or the fender body 1 and can be used with peace of mind. As described above, the shape of the shackle 11 that connects the ring member 5, the axial chain 2 and the circumferential chain 3 is twisted so that the shackle pin 12 is parallel to the surface of the fender body 1, that is, about 90
By twisting once, the shackle pin can be connected without damaging the hull or the fender body without using the end links as in the past, thus reducing the number of parts. In addition to being able to do, it requires less processing and man-hours,
The cost can be reduced.

[0012]

As described above, according to the present invention, the shackle for connecting the ring member to the axial chain and the circumferential chain is twisted so that the shackle pin is parallel to the surface of the fender body. Therefore, the shackle pin can be connected without damaging the hull or the fender body without using the end links as in the past, thus reducing the number of parts and processing and man-hours. There is an effect that the amount can be reduced and the cost can be reduced.
