Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a container connecting fitting related to container loading technology.

[Conventional technology and its problems]

For example, when loading a large number of containers on a ship, there is a risk that the cargo may collapse due to the shaking of the ship if they are simply stacked on top of each other. Various metal fittings for positioning or lashing are interposed between them.

However, as a type of lever fitting, conventionally, a fitting cone with a substantially cone-shaped tip is protruded from one side of the support plate, and a fitting cone with a sharply pointed tip is provided on one side of the support plate, and a fitting cone is provided at one diagonal corner of the support plate parallel to each other over the entire height. and an engaging cone with an engaging piece provided at an appropriate distance from the support plate is provided protruding from the other diagonal corner,
The engaging cone is inserted into the cone sockets fixed to the four corners of the lower surface of the container lifted by a crane, etc., and after rotating and engaging, the container is lowered and the engaging cone is placed on the ship floor or a lower layer that has been fixed to the floor in advance. It is known that the container is positioned and connected by fitting into cone sockets fixed to the four corners of the top surface of the container, but according to this conventional example, before the container is lowered and placed on the floor or lower container, There is a risk that the entire fitting may rotate and change direction due to an accidental collision, and the engaging cone may come off from the cone socket, causing the fitting to fall out of the container.

[Means for solving problems]

In view of the above points, the purpose of the present invention is to provide a connecting fitting that can be securely attached to a container that is lifted and loaded by a crane or the like without falling, and to achieve this purpose. An inset cone with a substantially cone-shaped tip is bored on one side of the support plate, and on the other side, sloped surfaces that are parallel to each other over the entire height are formed at one diagonal corner. In a container connecting fitting comprising an engaging cone provided with an engaging piece at an appropriate distance from the support plate at a diagonal corner, at least one of the diagonal corners on one side of the support plate In a position facing one side,
A locking portion at one end of a locking member that swings about a fulcrum is protrusively and retractably provided, and an operating portion at the other end is located in a horizontal hole formed in the fitting cone, and the locking member is arranged so that the fulcrum is a boundary between the locking member and the fulcrum. To provide a connecting fitting for a container whose posture is controlled by the weight balance of a lock part and an operating part.

[Effect]

In other words, the connecting fitting of the present invention prevents the return rotation of the engaging cone that has been inserted into and engaged with the cone socket through the interposition of the locking member that protrudes so as to come into contact with the inner edge of the engaging hole of the cone socket, thereby preventing the entire fitting from rotating and falling out. This is to prevent

Next, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 indicates a support plate formed into a flat plate shape with a required thickness, and a fitting cone 2 is integrally fixed to the lower surface of the support plate 1, and an engaging cone 5 is integrally fixed to the upper surface. ing.

The fitting cone 2, which has a substantially rectangular plan view and has a guide slope 4 formed by sharpening the lower end of a prismatic base 3 into a conical shape, has a center line 2a extending in the longitudinal direction of the rectangle that is connected to the supporting cone 2. It is arranged in a direction aligned with the center line 1a of the board 1. At the other diagonal corner of the engaging cone 5, which is based on the same rectangular plane as the rectangular plane of the base 3 of the engaging cone 2, and has sloped surfaces 6, 7 parallel to each other over the entire height at one diagonal corner. In this case, engaging pieces 8, 8 are formed at an appropriate distance l from the upper surface of the support plate 1, and when tracing the inclined surfaces 6, 7 and the outer edges of the engaging pieces 8, 8, the rectangle is rotated by about 30 degrees. It becomes a planar shape.

The fitting cone 2 has a horizontal hole 9 that penetrates through the left and right side walls of the base 3, and vertical holes 10a and 10b extend from the upper surface of the engaging cone 5 through the support plate 1 to the inner wall of the horizontal hole 9. It is set up. On one side of the base 3 of the fitting cone 2, an accommodation recess 11 is formed extending from the horizontal hole 9 to one end in the longitudinal direction and for attaching the locking member 14.
A shaft hole 12 parallel to the horizontal hole 9 is penetrated from the inner wall of the base 3 toward the other side surface of the base 3. The locking member 14 is fixed to the tip of the shaft pin 13 inserted into the shaft hole 12, and is rotatable together with the shaft pin 13. The other end is an operating part 16, and the former lock part 15 is configured to swing and rotate within a range that allows it to be projected and retracted above the support board 1 through a notch 18 in the support board 1 that is connected to the accommodation recess 11. . In the state of protruding from the upper surface of the support plate 1, the lock portion 15 is located near one of the inclined surfaces 6 of the engaging cone 2, and is housed within the rectangular plane of the base portion 3 of the fitting cone 2 when viewed from above. It is being

to operate the rocking of the lock member 14 (that is, the protrusion and retraction of the lock portion 15). In this lock member 14, the weight of the lock part 15 and the operating part 16 are balanced with respect to the fulcrum attached to the shaft pin 13, so that when the lock part 15 is projected above the support plate 1 ( The structure is such that it does not easily move from one direction to the other (solid line in FIG. 2) and when retracted (identical dotted line) unless there is an intentional swinging operation by the operator.

Next, a procedure for loading containers using the above-mentioned connecting fittings will be explained. As shown in FIGS. 7 to 9, a lower end cone socket 22 and an upper end cone socket 24 are provided at the corners of the container 21, each having engagement holes 23 and 25 on three sides.
Four metal fittings are fixedly installed at each of the upper and lower corners, and the metal fittings are used as a set of four to connect the lower end cone sockets 22 of the upper layer containers 21A and the upper end cone sockets 24 of the lower layer containers 21B, which are opposed to each other. Then, the containers 21A and 21B are loaded. The lower surface engaging hole 23 of the lower end cone socket 22 and the upper surface engaging hole 25 of the upper end cone socket 24, with which the cones 2 and 5 of the metal fitting directly engage, are formed by aligning rectangles of the same shape and size in the same direction. On the other hand, the metal fitting is attached so that the center line 1a of the support plate 1 is aligned with the center lines 23a, 25a extending in the longitudinal direction of the engagement holes 23, 25. The operation and procedure will be explained in bullet points below.

[Effects of the invention] As explained above, the container connecting fitting of the present invention has a fitting cone with a substantially conical tip formed on one side of the support plate, and one diagonal corner on the other side. For containers, in which inclined surfaces parallel to each other over the entire height are formed at the corners, and an engaging cone with an engaging piece provided at an appropriate distance from the support plate is bored at the other diagonal corner. In the connecting fitting, a lock portion at one end of the lock member that swings around a fulcrum is provided in a protruding and retractable manner at a position facing at least one of the one diagonal corner on one surface of the support plate; The operation part is located in a horizontal hole formed in the fitting cone, and the lock member is characterized in that its posture is controlled by a weight balance between the lock part and the operation part with the fulcrum as a boundary, The locking part of the locking member, which can be freely protruded and retracted from the top surface of the support plate, comes into contact with the inner edge of the engagement hole of the cone socket to prevent the metal fitting from rotating and falling off, so that it is securely attached to the container and also prevents it from falling off. This can prevent the occurrence of unforeseen accidents. Also, its structure is
Only a locking member with a locking part that can be protruded into and retracted from the support plate is attached in a swingable manner, so it is not significantly more complicated than horizontal hole products, and has fewer failures and is highly reliable. products can be provided. The other end of the locking member is positioned in a horizontal hole formed in the fitting cone, and the locking member can be operated from two directions of openings at both ends of the horizontal hole.
The posture is controlled by the weight balance of the locking part and the operation part with the fulcrum as the border, and it is configured so that it does not move unless there is an intentional rocking operation by the operator. It also has the ability to maintain its own posture even during periods.
Therefore, when removing the metal fittings from the container,
The operator only needs to momentarily touch the locking member to swing it, and there is no need to keep pressing the locking member.
