Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a rope anchoring device for containers, and is used to secure wires and ropes to prevent various types of cargo loaded and transported within the container from moving within the container. This invention relates to a plurality of rope anchors installed on the inner wall of a container in order to lock the wires and ropes when lashing the container.

Prior Art First, a conventional example of a rope anchor for a container will be explained with reference to FIGS. 1 and 2.

Figure 1 shows how the rope anchorage is installed on the inner wall of a container. An outer wall 1 made of corrugated board or the like is welded onto a bottom rail 2, and the inside of the outer wall 1 is made of plywood etc. A lining 3 consisting of is attached. Further, a floor wall 4 is welded to the bottom rail 2. The rope anchor 5 is welded to the inner surface of the outer wall 1, and the inner lining 3 is provided with an opening 6 for exposing the rope anchor 5 to the inside.

Details of the rope anchor 5 are shown in FIGS. 2 to 4, and an upper closing plate 10 and a lower closing plate are attached to the upper and lower open ends of the groove 9 of the main body 8, which is formed by pressing a metal plate into a substantially groove shape. 11 are welded in a horizontal state and a downwardly inclined state, respectively, a recess 12 is formed on the front side of the groove 9, and a rod-shaped body 13 is welded to cross the recess 12 in a flat state.

The rope anchoring device 5 is inserted into the groove 15 of the outer wall 1 inside the outer wall 1, and the left and right ear plate portions 8a of the main body 8 are attached to the outer wall 1 by welding, and the cargo inside the container is attached to the outer wall 1 using the wire. When securing the wire or rope 16 using the recess 12, as shown in FIGS.
I use it by locking it on 3.

At this time, if the wire or rope 16 is strongly pressed directly onto the peripheral edge 6a of the opening 6 of the lining 3 made of plywood or the like, the peripheral edge 6a will be easily damaged. Therefore, as shown in FIG. 2, a protector 17 made of a thin metal plate having an approximately gate-shaped cross section and an L-shaped cross section is stacked inside the opening peripheral portion 6a of the lining 3 in a sandwich pattern as shown in FIGS. 3 and 4. The left and right ear plate portions 8a of the main body 8 and the ear plate portion 1 of the upper closing plate 10 having an L-shaped cross section are connected by a plurality of rivets 18 and the like.
0a, so that the wire or rope 16 is not directly crimped onto the inner lining 3.

Problems to be solved by the invention However, this conventional example had the following defects.

(1) The rope locking device 5 is made by welding three press-formed parts: a main body 8, an upper closing plate 10, and a lower closing plate 11, and a rod-shaped body 13 is welded to these. Also, it requires a lot of welding man-hours and is extremely costly, making it unsuitable for mass production.

(2) In order to protect the opening periphery 6a of the lining 3, an extra protector 17 must be installed.

(3) Lining 3 was attached to the inner wall of the container because
It is originally used to transport various types of powder and granular materials. When the granular material is loaded, the granular material naturally enters the recess 12 of the rope locking portion 5 and flows from the upper and lower open ends of the groove 9 of the main body 8 into the gap between the lining 3 and the outer wall 1. Since this occurs, the upper and lower opening ends are closed with upper and lower closing plates 10 and 11. In addition, the lower blocking plate 1 is arranged so that the powder and granules contained in the recess 12 can naturally slide out of the recess 12 when the powder and granular material is discharged to the outside of the container.
1 is welded at a downward slope, but an angular step is formed at the welded portion 19, especially at the sloping upper end of the lower closing plate 11 shown in FIG. 4, and powder particles tend to get stuck there. Each time, the stuck powder had to be manually removed using a brush or the like, making the work extremely troublesome.

The present invention has been devised in view of the above-mentioned circumstances, and aims to provide a rope anchor for a container that is easy to manufacture, does not require the installation of an extra protector, and is less likely to cause powder or granules to stick inside the recess. That is.

Means for solving the problems The rope anchoring device for the container of the present invention has the following features:
A recess projecting toward the back side of a metal plate and an annular bulge for a protector formed around the recess on the front side of the metal plate are integrally formed by press working. The lower end of the recess is formed into an inclined surface that slopes downward toward the front side of the metal plate, and the rod-shaped body is installed to cross within the recess.

Function According to the rope anchor for a container of the present invention, the recess for attaching the rod-shaped body and the annular bulge for the protector are integrally pressed into one metal plate, and the lower end of the recess itself By tilting the lower closing plate downward toward the front side of the metal plate, there is no need to tilt and weld the lower closing plate to the lower end of the recess, which significantly reduces the number of processing steps, number of parts, and welding steps. I can do it. In addition, since the annular bulge for the protector is integrally provided on the front side of the metal plate, there is no need to attach an additional separately processed protector to the metal plate. Furthermore, since there is no need to tilt and weld the lower closing plate into the recess,
No angular steps or the like are formed within the recess. Therefore, the granular material that has entered the recess naturally and reliably slides out of the recess along the slope of the lower end of the recess, making it difficult for the granular material to stick inside the recess. Furthermore, the annular bulge for the protector formed around the recess also serves as a reinforcing rib for the metal plate.

Embodiment An embodiment of a rope anchor for a container to which the present invention is applied will be described below with reference to FIGS. 5 to 8.

The rope anchor 25 of the present invention is made of one metal plate 26.
As shown in FIG. 6, the metal plate 26 is formed by press working, and has a vertically elongated, substantially oval-shaped recess 27 in the center thereof that protrudes toward the back side (right side in FIG. 8) of the metal plate 26. It is molded into. The recess 27 has a substantially semicircular horizontal cross section as shown in FIG. Also, as seen in the vertical section shown in FIG. 8, both the upper and lower ends of this recess 27 are sloped surfaces 28 and 29 made of smooth curved surfaces, and in particular, the lower end slope 29 is on the front side of the metal plate 26. (Left side in FIG. 8) It is inclined downward toward 26a at a large angle and by a smooth curved surface. Further, a rod-shaped body 30 is horizontally traversed within the recess 27 and welded thereto.

An annular bulge 31 for a protector is pressed around the recess 27 on the front side 26a of the metal plate 26, and the bulge height of this annular bulge 31 is as shown in FIGS. 7 and 8. The length A is equal to or larger than the thickness B of the inner lining 32 made of plywood or the like. Further, the inner lining 32 is formed with a substantially elliptical opening 33 that fits into the outer periphery 31a of the annular bulge 31. The left and right end portions of the metal plate 26 are formed into a pair of ear plate portions 34a and 34b extending in the left and right sides, the upper end portion is formed into an upwardly inclined plate portion 35, and the lower end portion is bent at a substantially right angle. It is formed in the bending plate portion 36.

The rope anchor 25 of the present invention constructed as described above is inserted into the groove 38 of the outer wall 37 of the container, inside the outer wall 37 made of corrugated board or the like. Then, attach the bent plate part 36 to the bottom rail 3.
9, both left and right ear plate parts 34a, 34
b and the inclined plate portion 35 are welded to the outer wall 37 and attached. Then, the opening 33 of the inner lining 32 is fitted into the outer periphery 31a of the annular bulge 31.

According to the rope anchoring device 25 of the present invention attached to the inner wall of the container as described above, one metal plate 2
6 is press-worked, and a rod-shaped body 30 is welded into the recess 27 formed by the press-forming, and is composed of two parts, the metal plate 26 and the rod-shaped body 30. Therefore, the number of processing steps, the number of parts, and the number of welding steps are very small, and the manufacturing process is simple and low cost, making it suitable for mass production.

Further, the opening 33 of the lining 32 is fitted into the outer periphery 31a of the annular bulge 31, and the annular bulge 31
Since the height A of the bulge is equal to or greater than the thickness B of the inner lining 32, as shown in FIGS.
As shown in the figure, when the wire or rope 40 is locked to the rod-shaped body 30 using the recess 27, the wire or rope 40 is not directly crimped to the lining 32, and the lining 32 is attached to the wire or rope 40.
There is no possibility that it will be damaged by zero.

Further, since the lower end side inclined surface 29 of the recess 27 is inclined downward at a large angle and a smooth curved surface toward the outside of the recess 27, after the powder and granular material is loaded and transported in the container, When discharging the powder and granules out of the container, the powder and granules that have entered the recess 27 can be slid down naturally and reliably by the lower end side inclined surface 29, and the powder and granules enter the recess 27.
7. Hard to get stuck inside.

In addition, one metal plate 26 is pressed to form the recess 2.
The structure in which 7 is formed is a robust structure in itself, and the pressed annular bulge 31 constitutes a reinforcing rib, so that an extremely robust rope anchor 25 can be provided. Because of this, a thin plate can be used as the metal plate 26, which is very easy to press and is very useful for weight reduction.

Effects of the invention As stated above, the rope anchorage for containers of the present invention can significantly reduce the number of processing steps, number of parts, and welding steps, making it extremely easy to manufacture, low cost, and easy to mass produce. Very expensive. Moreover, since there is no need to additionally attach a separately processed protector to the rope anchor, the number of installation steps and number of parts can be reduced. Furthermore, since the powder particles are less likely to stick in the recesses, there is no need to manually remove the powder particles stuck in the recesses using a brush or the like. Furthermore, since the annular bulge for the protector also serves as a reinforcing rib for the metal plate, it is possible to provide a robust rope anchor even with a thin metal plate; It is also easy to process.
