[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cone lock according to a technology for securing and securing a container.

[0002]

2. Description of the Related Art Corn locks are used, for example, on ships.
It is used between two containers when two containers are stacked one on top of the other and is used for connecting and securing the two containers. The usual usage is a lower cone socket of the upper container (upper cone socket). After being hanged together with the upper container by a crane and attached to the upper cone socket (lower cone socket) of the lower container, as a special usage,
Conversely, it may be attached to the upper cone socket of the lower container and then attached to the lower cone socket of the upper container suspended by the crane.
However, the conventional cone lock has a disadvantage in that, in the latter special use, the operation lever must be manually operated for engagement of the upper cone.

In addition, with the recent change of the ISO standard, the mounting of the cone lock in the upside down direction is prohibited, and the operation lever is located on the left side (left end) of the swing range. Position (lock position), and the right (right end) position indicates that the lower cone is at the disengagement position (open position). It is necessary to adapt the structure and operation of this to this standard.

[0004]

Therefore, the present invention enables the upper and lower cones to be automatically engaged with each other regardless of the above-mentioned normal use and special use, and conforms to the ISO standard. It is an object to provide a cone lock with structure and operation.

In the conventional cone lock, the case is divided into two parts for assembling the parts, and the position of the division may be just over the periphery of the opening of the case. The strength of the periphery of the part is insufficient, which may cause the following inconvenience.

That is, when loading and unloading a container, a situation in which the cone lock erroneously collides with the vicinity of the engagement hole of the lower cone socket of the lower container while the cone lock is suspended by the crane occurs. Then, the impact due to the collision acts on the case directly or via the cone, whereby the periphery of the opening of the case may be damaged at the split position.

Accordingly, it is another object of the present invention to provide a cone lock capable of increasing the strength of the periphery of the opening of the case and preventing the case from being damaged at the periphery of the opening.

A lock, wherein when the upper fitting portion is aligned with the engagement hole of the upper cone socket and the upper cone is pressed against the upper cone socket, the upper cone automatically moves to the upper cone socket by the operation of the cam surface and the spring means. In this state, when the lower fitting portion is aligned with the engaging hole of the lower cone socket and the lower cone is pressed against the lower cone socket, the lower cone has its cam surface and spring means. When the lower cone is pressed against the lower cone socket by automatically engaging the lower cone socket by the operation of the lower cone socket, the lower fitting portion is aligned with the engagement hole of the lower cone socket, and the lower cone is pressed against the lower cone socket. The cone automatically engages with the lower cone socket by the operation of the cam surface and the spring means. In this state, the upper fitting portion is aligned with the engaging hole of the upper cone socket. When the side cone is pressed relatively to the upper cone socket, the upper cone automatically engages with the upper cone socket by the operation of the cam surface and the spring means, and when both the upper and lower cones are at the engagement stop position, the operation lever is moved. When pivoted to the manual disengagement position, the upper cone maintains the engaged state, the lower cone moves to the disengaged position, and when the lower cone is manually rotated in this state, the upper cone is rotated. It is characterized by shifting to the disengaged position.

A cone lock according to a second aspect of the present invention is provided with a case having an upper and lower fitting portion which is fitted into the engaging hole of the upper and lower cone sockets in a state of being prevented from rotating, and is rotatably inserted through the case.

Further, a cone lock according to a fourth aspect of the present invention includes a case in which a shaft provided with upper and lower cones is rotatably mounted and an operation lever for rotating the shaft is swingably mounted in an opening. Wherein the case has a split structure so as to be divided into a case body having the opening peripheral edge over the entire circumference thereof and a case divided body combined with the case body. When the case body is combined with the notch, a bolt groove is provided in the case body and the case body to be an insertion part into which an assembly bolt is inserted when the case division body is combined. When the assembly bolt is inserted into the insertion part, the assembly bolt The case is engaged with an edge of a bolt groove of the main body and is prevented from falling off in a combination direction of the case main body and the case divided body. Waritai is characterized in that the edge of the bolt groove the assembly bolt engaged with the case body is prevented from coming off the combination direction of the case body and the case split body engages.

The cone lock according to the first or second aspect of the present invention having the above configuration operates as follows with the above configuration.

(1) During normal use: This normal use is
As described above, the cone lock is first attached to the lower-side cone socket (upper cone socket) of the upper container, and then suspended with the upper container by a crane,
The cone lock of the present invention is retrofitted to the upper cone socket (lower cone socket) of the lower container, and operates as follows.

[0014] First, when holding the cone lock in hand, aligning the upper fitting portion of the case with the engaging hole of the upper cone socket of the upper container, and pressing the upper cone against the upper cone socket, the upper cone is pressed. By the operation of the cam surface and the spring means, it automatically engages with the upper cone socket (pre-setting). Next, the cone lock is hung by the crane together with the upper container, the lower fitting portion of the case is aligned with the engagement hole of the lower cone socket, and the lower cone is pressed against the lower cone socket. The cone automatically engages (retrofits) the lower cone socket by actuation of its cam surface and spring means. Therefore, fully automatic mounting is possible in the sense that there is no need to manually operate the operation lever.

The fact that the automatic mounting is possible as described above means that the operation lever is never located at the manual disengagement position due to engagement with the stopper means during the above operation. Therefore, by setting this position to the right (right end) of the swing range according to the ISO standard, the operation of the cone lock can be made to conform to the ISO standard.

Further, in the present invention, when the operating lever is at the engagement stop position, the upper and lower cones are both located at the engagement stop position, and the lower cone is located at the automatic release position. Since the shaft can be displaced relative to the operation lever so as to be in a state, the operation lever does not swing at all when retrofitted. Also, since the upper cone is displaced in the engagement direction more than the lower cone, the operation lever slightly swings at the time of initial attachment, but the swing angle is set to the manual disengagement position. Not big enough to reach. Therefore, the control lever automatically returns to the engagement stop position without engaging with the stopper means at the time of retrofitting and pre-attaching, and does not stop at this position without reaching the manual disengagement position. Therefore, if the engagement stop position is on the left side (left end) of the swing range and the manual disengagement position is on the right side (right end) of the swing range, there is no stop at the above operation. The operation is also described in the ISO
It becomes possible to conform to the standard.

(2) Special use: This special use is
As described above, the cone lock is attached to the upper cone socket (lower cone socket) of the lower container, and then retrofitted to the lower cone socket (upper cone socket) of the upper container suspended by the crane. Yes, the cone lock of the present invention operates as follows.

That is, first, holding the cone lock in hand, aligning the lower fitting portion of the case with the engagement hole of the lower cone socket of the lower container, and pressing the lower cone against the lower cone socket. The lower cone is automatically engaged with the lower cone socket by actuation of the cam surface and the spring means (pre-setting). Next, the upper container is hung by a crane, the engagement hole of the upper cone socket is aligned with the upper fitting portion of the case, and the upper cone socket is pressed relatively to the upper cone. Automatic engagement with the upper cone socket by actuation of the cam surface and the spring means (retrofit). Therefore, fully automatic mounting is possible in the sense that it is not necessary to manually operate the operation lever.

The fact that the automatic mounting is possible as described above means that the operation lever is never located at the manual disengagement position due to engagement with the stopper means during the above operation. Therefore, by setting this position to the right (right end) of the swing range according to the ISO standard, the operation of the cone lock can be made to conform to the ISO standard.

In the present invention, when the operating lever is at the engagement stop position, the upper and lower cones are both at the engagement stop position and the lower cone is at the automatic release position. Since the shaft can be relatively displaced with respect to the operation lever so as to be in a state, the operation lever does not swing at all at the time of pre-assembly. Also, since the upper cone is displaced in the engagement direction more than the lower cone, the operating lever slightly swings when retrofitted, but the swing angle is set to the manual disengagement position. Not big enough to reach. Therefore, the control lever automatically returns to the engagement stop position without engaging the stopper means at the time of pre-attachment and post-attachment, and does not stop at this position without reaching the manual engagement release position. Therefore, if the engagement stop position is on the left side (left end) of the swing range and the manual disengagement position is on the right side (right end) of the swing range, there is no stop at the above operation. The operation is also described in the ISO
It becomes possible to conform to the standard.

(3) Removal: When the cone lock mounted between the upper and lower containers is to be removed from both containers, the cone lock is lifted together with the upper container by a crane, and the cone lock is first removed from the lower container (lower cone). Socket) and then from the upper container (upper cone socket). This is common for normal and special use.

That is, first, when the operating lever is manually operated to swing to the manual engagement releasing position by engagement with the stopper means, the upper cone maintains the engagement state although the engagement angle becomes shallower. The lower cone moves to the disengaged position prior to the upper cone. Therefore, when the upper container is lifted by the crane, the cone lock is first detached from the lower cone socket of the lower container while being suspended from the upper container. Next, when the lower cone of the cone lock suspended in the upper cone socket of the upper container is manually rotated in the disengagement direction, the upper cone shifts to the disengagement position. Therefore, the cone lock is removed from the upper cone socket of the upper container so that the entire cone lock is received by hand. During this detaching operation, the operating lever is first shifted to the manual disengagement position. Therefore, by setting this position to the right (right end) of the swing range according to the ISO standard, the operation of the cone lock can be made to conform to the ISO standard.

In the present invention, when the operating lever is at the manual disengagement position by the stopper means, the lower cone is at the manual disengagement position and the upper cone is at the disengagement position. Since the shaft can be displaced relative to the operating lever so that it is positioned, the lower cone of the cone lock suspended in the upper cone socket of the upper container is manually disengaged in the disengagement direction. When the upper lever is rotated to the disengaged position, the upper cone can be disengaged from the upper cone socket, and thus the operating lever is moved to the manual disengaged position at one end of the swing range. The fact that the upper cone can be further rotated in the disengagement direction after the movement is a unique operation because the shaft and the operation lever can be relatively moved in the rotation direction.

Further, the present invention has the above-mentioned structure.
In the cone lock according to the present invention, the split structure of the case is set so as to be divided into a case main body having an opening peripheral edge over the entire circumference and a case divided body combined with the case main body. The peripheral edge of the opening can be integrated over the entire circumference, thereby increasing the strength of the peripheral edge of the opening. Note that the two-part case structure according to the present invention does not divide the case into two parts as in the conventional case, but rather divides the case into a relatively large part and a relatively small part. Is referred to as a case main body, and the latter is referred to as a case divided body, and the former case main body includes the entire periphery of the opening.

In addition to the above, in the cone lock according to the fourth aspect of the present invention having the above-described configuration, when the case split body is combined with the cutout of the case body divided into two as described above, the assembly bolt is inserted. A bolt groove serving as an insertion portion is provided in each of the case body and the case divided body, and when the assembly bolt is inserted into the insertion portion, the assembly bolt engages with an edge of the bolt groove of the case body, so that the case body is And the case divided body is prevented from falling off in the mounting direction, and the case divided body is engaged with the assembly bolt engaged with the case body with the edge of the bolt groove. It is configured so that it does not come off in the case Also, it is possible to assemble the case, Warikata depending on, it is possible to reduce the necessary number of assembly bolts.

Also, the engagement end portion 8a protrudes clockwise outward from the planar outer shape of the lower fitting portion 5 of the case 2 by a predetermined angle, and is also at the lock position. However, as described above, the upper cone 7 and the lower cone 8 are mutually displaced in the rotational direction and are arranged in a plane x-shape, and the upper cone 7 protrudes at a larger angle than the lower cone 8. ing. This initial movement posture is also a locked state at the time of completion of mounting the cone lock 1.

(B) Mounting work 1 in normal use From the initial movement posture of the above (a), the cone lock 1 is connected to the lower surface cone socket (upper cone socket) 31 of the upper container.
In order to mount the cone lock 1 on the hand, the upper cone 7 is pressed against the upper cone socket 31 from below without holding the cone lock 1 in a hand and manually operating the operation lever 9. Then, since the upper cone 7 is provided with the cam surface 7b having a twisted slope in advance, the rotational moment generated by pressing the cam surface 7b against the edge of the engagement hole 31a of the upper cone socket 31 causes The upper cone 7 rotates counterclockwise against the elasticity of the elastic means 10,
As shown in FIG. 5, it is possible to pass through the engaging hole 31a at the same time as the plane outer shape of the upper fitting portion 4 is overlapped.
1a, is inserted into the upper cone socket 31,
At the same time as having passed through the engagement hole 31a, it is pulled back by the elastic means 10 and returned to the lock position shown in FIG. At this time, the operation lever 9 swings rightward from the initial movement position A in FIG. 4 to the position B in FIG. 5, and then automatically returns leftward from the position B in FIG. 5 to the position A in FIG. I do.

(C) Mounting work 2 for normal use Next, when the container in which the cone lock 1 is suspended by the above work b is stacked on another container by a crane or the like, the operation lever 9 is manually operated. Without pressing the lower cone 8 against the upper cone socket (lower cone socket) 32 of another container from above. Then, since the lower cone 8 is provided with the cam surface 8b in the form of a twisted slope in advance, the rotational moment generated when the cam surface 8b is pressed against the edge of the engagement hole 32a of the lower cone socket 32. As a result, the lower cone 9 rotates counterclockwise against the elasticity of the elastic means 10, and can pass through the engaging hole 32a at the same time as overlapping with the planar outer shape of the lower fitting portion 5 as shown in FIG. Actually, it is inserted into the lower cone socket 32 through the engaging hole 32a, and at the same time as having passed through the engaging hole 32a, pulled back by the elastic means and returned to the lock position shown in FIG. At this time, the operation lever 9 is assembled so as to be relatively rotatable with respect to the shaft 6 as described above, and the relative rotatable range is made to coincide with the rotation angle of the lower cone 8 from FIG. 4 to FIG. Does not move at all or hardly from the initial movement position A. The initial movement position A is a lock display position that indicates that the cone lock 51 is at the lock position. By the above operations B and C, the cone lock 1 is connected to the upper and lower cone sockets 31 and 32, respectively.

(D) Removal work 1 Next, when the upper container of the vertically stacked containers is lifted by a crane or the like and lowered from above the lower container, the operation is performed using a working bar prior to this. The lever 9 is moved from the initial movement position A in FIG. 4 to the manual open position C in FIG. That is, the operating lever 9 is swung rightward from the initial movement position A in FIG.
The operating lever 9 is brought into contact with a projection-shaped swing regulating stopper 12 provided in advance at the upper and lower edges of the opening 2a, and at this position, the operating lever 9 is opposed to the elasticity of the second elastic means 13 such as a spring provided at the base end thereof. Then, the lever is further swung to the right in this state so that the engaging portion 11 gets over the swing restricting stopper 12. When the force that has been pulled out toward the user is released and elastic return is performed in the proximal direction, the operating lever 9 engages with the swing restricting stopper 12 in the engaging portion 11 in the left swing direction, and the swing lever Unless the lever 9 is pulled out again intentionally, the swing lever 9 does not swing freely, and at this time, the lower cone 8 is moved to the lower fitting portion 5 at an angle position deeper than the automatic open position in FIG. Located within the planar outline. Therefore, after this operation is completed, the upper container is lifted by a crane or the like, and the lower cone 8 is pulled out from the lower cone socket 32. The stopper means 21 includes the engaging portion 11 and the swing regulating stopper 12 on the assumption that the operation lever 9 can be pulled out. The stopper means 21 is a means for preventing the cone lock 1 from falling in the sense that the upper cone 7 does not shift to the disengagement position C unless the operation lever 9 is manually moved over intentionally. .

(E) Removal work 2 In order to remove the cone lock 1 from the upper cone socket 31 following the above work d, hold the lower cone 8 in the hand and manually rotate it to the left, The cone 7 is rotated leftward from the locked state in FIG. 7 to the open position in FIG. 5, and the upper cone 7 is pulled out of the upper cone socket 31 in this state. Therefore, the cone lock 1 is removed from the upper and lower cone sockets 31 and 32 by the above operations C and D.

Also, the cone lock 1 was originally developed for the purpose of eliminating work at height,
Depending on the situation, the cone lock 1 may be mounted on a container stacked in several stages, and a container suspended by a crane or the like may be mounted on the container lock. The work is special as follows.

(F) Mounting work 1 by special use From the initial movement posture of the above-mentioned (1), when the lower cone 8 is pressed onto the lower cone socket 32 from above without operating the operation lever 9 manually, as described above. Since the lower cone 8 is provided with a cam surface 8b having a twisted slope in advance,
The cam surface 8b is provided in the engagement hole 32 of the lower cone socket 32.
6A, the lower cone 9 rotates counterclockwise against the elasticity of the elastic means 10, and the lower fitting portion 5 is rotated as shown in FIG.
At the same time as being overlapped with the outer shape of the upper surface, and can pass through the engaging hole 32a, and is actually inserted into the lower cone socket 32 through the engaging hole 32a, and at the same time as passing through the engaging hole 32a. And is returned to the lock position shown in FIG. At this time, the operation lever 9 is assembled so as to be relatively rotatable with respect to the shaft 6 as described above, and the relative rotatable range is made to coincide with the rotation angle of the lower cone 8 from FIG. 4 to FIG. Does not move at all or hardly from the initial movement position A.

(G) Mounting work 2 by special use Then, when another container suspended by a crane or the like is put on a container having the cone lock 1 mounted on the upper surface by the above work, From the initial movement position in (1) above, without manually operating the operation lever 9,
When the upper cone socket 31 is pressed against the upper cone 7, as described above, the upper cone 7 is provided with the twisted inclined cam surface 7b, and the cam surface 7b is engaged with the engagement hole 31a of the upper cone socket 31. The upper cone 7 rotates counterclockwise against the elasticity of the elastic means 10 due to the rotational moment generated by being pressed against the edge of the upper part, and at the same time as overlapping with the plane outer shape of the upper fitting part 4 as shown in FIG. The elastic means 10 can pass through the engaging hole 31a, is actually passed through the engaging hole 31a, is inserted into the upper cone socket 31, and simultaneously passes through the engaging hole 31a.
And is returned to the lock position shown in FIG. At this time, the operation lever 9 swings rightward from the initial movement position A in FIG. 4 to the position B in FIG. 5, and then automatically returns leftward from the position B in FIG. 5 to the position A in FIG. I do. By the above operations (f) and (g), the cone lock 1 is connected to the upper and lower cone sockets 31 and 32, respectively.

(H) Removal work by special use The procedure of the removal work at the time of special use by the above (f) and (g) is the same as the removal work at the time of normal use by the above (d) and (e).

The cone lock 1 according to the present embodiment is characterized in that the following effects are achieved by the above-described configuration.

That is, the upper and lower cones 7, 8 are automatically engaged with the cone sockets 31, 32 regardless of the normal use or the special use as described above. There is no need to operate. Therefore, the mounting operation can be facilitated.

The lower cone 8 is connected to the cone socket 32.
Unless the operation lever 9 is manually moved to the manual open position C at the right end of the swing range when the operation lever 9 is removed from the device, the operation lever 9 is never located at the manual open position C. Therefore, the fact that the operating lever is located to the left (left end) of the swing range indicates that the upper and lower cones 7 and 8 are both in the engaged position (locked position), and is located to the right (right end). Indicates that the lower cone 8 is at the disengaged position (open position), and the cone lock 1 has a structure and operation that conforms to the ISO standard described above.

In addition, the cone lock 1 according to the above embodiment has the following configuration with respect to the split structure of the case 2.

That is, as shown in FIG. 8, the case 2 has a split structure at a position that does not cover the periphery of the opening 2a provided in the case 2 for connecting the operation lever 9 to the shaft 6. Case body 2 by this split
A divided case (also referred to as a sheet) 2 is provided in the cutout 14 of A.
Bolt grooves 17, 18 which become lateral hole-shaped insertion portions 16 into which the assembly bolts 15 are inserted when B is combined are provided corresponding to the case main body 2 </ b> A and the case divided body 2 </ b> B, respectively. When the assembling bolt 15 is inserted into the insertion portion 16 composed of the casing body 2A, the assembling bolt 15 engages with the edge of the bolt groove 17 of the case body 2A to prevent the case body 2A and the case divided body 2B from being detached in the assembling direction. In addition, the case split body 2B is engaged with the assembly bolt 15 engaged with the case main body 2A at the edge of the bolt groove 18, and is also prevented from falling off in the assembly direction of the case main body 2A and the case split body 2B. It has a configuration.
