Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container connecting tool for connecting stacked upper and lower containers.

[0002]

2. Description of the Related Art Generally, in the case of transporting a large number of containers by ship, a container connecting tool is installed between corner metal fittings facing each other at the top and bottom of containers stacked in multiple stages, and the upper and lower corner metal fittings are connected by the container connecting tool. The container is secured with a fastener to stabilize the container.

As a container connector, a flange is provided on the connector body between the corner fittings of the upper and lower containers, and a pair of projecting portions that are fitted almost exactly into the engaging holes of the respective corner fittings. A shaft insertion hole penetrating from the upper surface of the lower part to the lower surface of the lower protruding part is formed, and cones are provided at the upper and lower ends of the rotatable rotary shaft inserted in the shaft insertion hole. It is conventionally known that the lower cone is engaged with the peripheral portion of the engaging hole, and the lower cone is engaged with the peripheral portion of the engaging hole of the lower corner fitting to connect the upper and lower containers.

In the above container connector, the spring is elastically deformed by the rotation of the rotating shaft, and the restoring elasticity causes the rotating shaft to rotate to a position where the upper and lower cones are in the engaged state.

When connecting the containers using the above-mentioned container connecting tool, a rotating force is applied to the lower cone to rotate the rotating shaft, and the upper cone is held in the disengaged state so that it is contained in the outer peripheral surface of the upper protrusion. Insert the upper protrusion into the engaging holes of the corner metal fittings at the four corners of the lower surface of the container that are suspended and supported, and rotate the rotating shaft by the restoring elasticity of the spring with the flange abutting against the lower surface of the corner metal fitting, The container connector is connected to each of the corner fittings by engaging one end of each of the upper cones with the peripheral edge of the engaging hole. When the container is placed on the container previously stacked in the connected state of the container connecting tool and the lower cone is inserted into the engaging holes of the corner fittings provided at the four corners of the upper surface of the lower container, When the lower cone is rotated to the disengagement position by contact with the inner peripheral edge of the engagement hole and the lower cone is inserted to the position where it passes through the engagement hole, the elastic force of the spring rotates the rotating shaft to rotate the lower cone. Is returned to the engaged state, and the one end portions of the lower cone are engaged with the peripheral edge portion of the engagement hole.

When loading and unloading containers,
The lower cone is disengaged by rotating the rotating shaft by an external operation, and the upper container is pulled up while keeping the disengaged state, and the lower cone is pulled out from the engaging hole of the corner fitting in the lower container. I try to pull it up.

Here, as an operating mechanism for rotating the rotary shaft by an external operation, as shown in FIGS. 9 (I) to (III), a rotary shaft 72 having an upper cone 70 and a lower cone 71 at both ends thereof. The wire 73 is connected to, and an operation portion 74 is provided at an end portion of the connector main body (not shown) that faces the outside from the outer periphery of the flange, and the operation portion 74 is engaged with an engagement fitting provided at the tip of the operation rod. It is known that the operation part 74 is pulled down to pull the wire 73 out of the connector body, and the wire 73 is pulled out to rotate the rotary shaft 72 in a direction in which the lower cone 71 is disengaged.

In an operating mechanism using a wire, a protruding portion 75 having a wire insertion groove is provided on the outer periphery of a flange formed on the connector main body, and the wire 73 is pulled out by the engagement of the protruding portion 75 and the operating portion 74. The lower cone 71 is temporarily held in the disengaged state.

[0009]

By the way, in the container connector using the wire for the operation mechanism, when the container connector is connected to the corner fitting of the lower portion of the suspended container, the rotational force is applied to the lower cone 71. When applied and rotated in the disengagement direction of the upper cone 70, the wire 73 is pushed out of the connector body and hangs downward, and the upper protrusion is inserted into the engaging hole H of the corner fitting and the hand is pushed from the lower cone 71. When the wire is released, the wire 73 may be drawn into the connector main body in a hanging state, and the operation portion 74 may be engaged with the protruding portion 75 during the drawing and the lower cone 71 may be held at the disengaged position. .

In this case, although the upper cone 70 is engaged with the peripheral portion of the engaging hole H and the container connecting tool is held in the connected state, the lower cone 71 is in the disengaged state, so that in the lower container. Even if the lower cone 71 is inserted into the engaging hole H of the corner fitting, the lower cone 71 does not enter the engaged state, and the upper and lower containers are transported in a non-connected state, and the container collapses due to the shaking of the vessel. There is a risk of

In the conventional container connector, when the lower cone 71 is engaged, the amount of engagement with the peripheral portion of the engaging hole H is small, so that the container connector is used upside down. There is a risk of dropping if the container connector is impacted while it is connected to the lower corner fitting of the suspended container.

An object of the present invention is to provide a container connector having excellent safety that can reliably connect upper and lower containers.

[0013]

In order to solve the above-mentioned problems, according to the present invention, a substantially oval engagement formed on the corner metal fittings above and below a flange disposed between the corner metal fittings of the upper and lower containers. A pair of protrusions that are fitted almost exactly into the holes is provided, and a shaft insertion hole that opens at the end faces of the pair of protrusions and a lever storage hole that communicates with the shaft insertion hole and opens at a part of the outer periphery of the flange are formed. And a rotary shaft that is inserted into the shaft insertion hole and has a cone that is engaged with the peripheral edge of the engagement hole at the upper and lower ends, and an operating portion at one end. A lever member that is incorporated in the lever housing hole so that its operating portion is located outside, and is swingably supported in a direction in which both end portions move up and down about a substantially central portion in the length direction thereof; Lever part by pulling down the operation part When swinging, the cam mechanism that presses the cam projection provided on the outer periphery of the rotating shaft at the other end to rotate the rotating shaft toward the disengagement position where the lower cone is within the outer peripheral surface of the lower protruding portion. And a temporary locking mechanism for temporarily locking the operating part of the lever member in a pulled-down state, and elastically deformed by the rotation of the rotary shaft, and the restoring elasticity causes one side at both ends of the cone to move outward from both side surfaces of the protruding part. A pair of cones are provided with the phases thereof shifted in the circumferential direction of the rotary shaft so as to be disengaged by the rotation of the rotary shaft in different directions. The adopted structure was adopted.

Here, the lever member has a guide hole extending in both end directions in a lever main body supported swingably around a substantially central portion in the length direction, and a wire insertion hole communicating from the one end to the guide hole. And an operating portion is provided at one end of the wire slidably inserted into the wire insertion hole, and a retaining projection is provided at the other end of the wire located in the guide hole. Alternatively, the rear end of the operation portion may be brought into contact with one end of the lever body.

Alternatively, a lever body supported so as to be swingable about a substantially central portion in the longitudinal direction is provided with a guide hole extending long in both end directions, and a wire insertion hole communicating from the one end to the guide hole. An operating portion is provided at one end of the wire slidably inserted in the wire insertion hole, and a retaining projection is provided at the other end of the wire located in the guide hole,
The protrusion may be pressed by a spring so that the rear end of the operating portion is brought into contact with one end of the lever main body.

In the container connector using such a lever member, wire insertion grooves are formed above and below the inner circumference at one end opening of the lever accommodating hole as a temporary fixing mechanism, and the wire insertion grooves are operated on the outer circumference of the end of each wire insertion groove. It is possible to employ a structure in which a rear end surface of the portion is formed with an inclined engagement surface that can be engaged.

Further, the lever member has a structure in which an operating portion having a larger diameter than the shaft body is integrally provided at one end of a cylindrical shaft body which is swingably supported about a substantially central portion in the longitudinal direction. Can be adopted. In this case, as the temporary fixing mechanism, it is possible to adopt a structure in which an arcuate recess is formed at the end of the inclined cam surface of the cam projection so that the tip of the shaft body can be engaged.

As described above, by shifting the phase in the circumferential direction of the rotary shaft so that the pair of cones provided at both ends of the rotary shaft are disengaged in different rotation directions of the rotary shaft,
It is possible to prevent the inconvenience that the lower cone is held in the disengaged state when the upper cone is rotated from the disengaged state back to the engaged state.

Therefore, the upper and lower containers can be reliably connected by the container connecting tool.

Further, since the engagement area of each cone with respect to the peripheral edge portion of the engagement hole can be made large, even when the container connecting tool is used upside down, the container connecting tool is installed at the lower corner of the suspended container. Even if an impact is applied to the container connecting tool in the connected state, the container connecting tool does not drop and can be safely used even when the container connecting tool is used upside down.

Here, a stopper insertion hole that penetrates vertically is formed in the flange of the container connector, and a vertically long pin hole communicating with the shaft insertion hole is provided on the inner periphery of the stopper insertion hole, and the stopper insertion hole is formed. A pin to be inserted into the pin hole is provided on the outer periphery of the stopper inserted into the hole, and the outer periphery of the rotary shaft is opposed to the pin in the circumferential direction of the rotary shaft in a state where the pins are in contact with both ends of the pin hole. Protrusions that prevent the rotating shaft from rotating in the direction in which the upper cone disengages are provided on the stopper when the container connector is connected to the corner metal fittings at the four corners of the lower surface of the suspended container. This prevents the upper pin from rotating in the disengaging direction of the upper cone by facing the protrusion provided on the rotating shaft in the circumferential direction, so that the container connecting tool can be securely held in the connected state. It is possible to further enhance the safety.

The protrusion 17 is pressed by the spring 18 supported by the wire 15 so that the rear end of the operating portion 16 is pressed against one end of the lever body 12.

A pusher 19 is provided at the other end of the lever body 12.
And a fulcrum pin 20 is provided on both side surfaces of the lever main body 12 at substantially central portions in the longitudinal direction. The fulcrum pin 20 is a pin hole 21 formed on both sides of the lever housing hole 5.
The fulcrum pin 20 is rotatably supported by being inserted therein.
The lever body 12 is swingable in the direction in which both ends move up and down.

The operating portion 16 is composed of a round shaft, and a flange 16a is provided at one end thereof.

The lever member 11 swings around the fulcrum pin 20 by engaging a hook f provided at the tip of the operating rod B with the operating portion 16 and pulling it down. At this time, the wire 15 is pulled out from one end of the lever body 12.

The rocking motion of the lever member 11 is caused by the cam mechanism 2
It is converted into a rotary motion of the rotary shaft 6 via 2. At this time, the rotating shaft 6 is rotated in the direction in which the lower cone 7b is disengaged.

The cam mechanism 22 is provided with a cam projection 23 on the outer circumference of the rotary shaft 6, and when the other end of the lever body 12 swings upward, the pusher 19 provided on the other end of the lever body 12 is moved. The inclined cam surface 23a of the cam projection 23 is pressed by.

Here, the cam projection 23 is the lever member 11
When the container is in a neutral state where it is substantially horizontal, it is provided on the upper side of one side and the lower side of the other side of the pusher 19, and even when the container connector is used upside down, the rotary shaft 6 is moved upward by pulling down the operating portion 16. The cone 7a can rotate in the disengaging direction.

The operating portion 16 is held in the pulled-down state by the temporary fixing mechanism 24. The temporary fixing mechanism 24 has an operation portion insertion hole 25, which is a tapered hole into which the operation portion 16 is inserted, at one end of the lever housing hole 5, and a wire insertion groove 26 above and below the inner circumference of the operation portion insertion hole 25. An inclined engagement surface 27 is formed on the outer periphery of the end portion, and the operation portion 16 is formed on the engagement surface 27.
The end faces of are engaged.

The upper cone 7a is held in the engaged state by the stopper mechanism 28 shown in FIGS. The stopper mechanism 28 has a stopper insertion hole 29 that vertically penetrates the flange 2, and a vertically long pin hole 30 that communicates with the shaft insertion hole 4 is provided on the inner periphery of the stopper insertion hole 29. Stopper 31 inserted in 29
A pin 32 is provided on the outer periphery of the pin 32, and the pin 32 is attached to the pin hole 3
0, while the pin hole 30
When the pins 32 are in contact with both ends of the
2 is provided with a pair of protrusions 33 that face each other in the circumferential direction of the rotary shaft 6, and prevents the rotary shaft 6 from rotating in the direction in which the upper cone 7a is disengaged by the contact of the pin 32 with each of the protrusions 33. ing.

The container connector shown in the embodiment has the above structure, and when connecting the containers A ₁ and A ₂ ,
The container A ₁ is suspended, and the container connecting tool A is attached to the corner metal fittings C at the four corners of the lower surface of the container A ₁ which is suspended and supported.
After connecting _0s , the container A ₁ is placed on the previously stacked container A ₂ .

Container connector A ₀ for the corner fitting C
At the time of coupling, the stopper 31 is pushed up, the pin 32 provided on the stopper 31 is displaced in the axial direction of the rotary shaft 6 with respect to the projection 33 provided on the outer periphery of the rotary shaft 6, and the stopper 31 is removed. The upper cone 7a is held in the pushed-up state, a rotational force is applied to the lower cone 7b, and the upper cone 7a is brought into the disengaged state in which the upper cone 7a is accommodated in the outer peripheral surface of the upper protrusion 3a by the rotation of the rotating shaft 6.

When the rotary shaft 6 rotates, the spring 10 is elastically deformed, and a restoring rotational force is applied to the rotary shaft 6 by its restoring elasticity.

After the upper cone 7a is in the disengaged state, the state is maintained, and the upper projecting portion 3a is inserted into the engaging holes H of the corner fittings C at the four corners of the lower surface of the container A ₁ which is suspended and supported. After the flange 2 is brought into contact with the lower surface of the corner fitting C, the holding of the cone 7b is released.

By releasing the holding of the lower cone 7b, the rotary shaft 6 is returned and rotated by the restoring elasticity of the spring 10, and the upper cone 7a rotates together with the rotary shaft 6 so that one side of both ends engages with the peripheral edge of the engaging hole H. And the container connector A ₀ is connected to the corner fitting C by the engagement.

After connecting the container connecting tool A ₀ , the stopper 3
When the push-up of 1 is released, the stopper 31 moves down to the position where the pin 32 is supported by the lower end of the pin hole 30 by its own weight. Due to this lowering, the stopper 31 is held in a state where its lower portion projects below the stopper insertion hole 29, and the pin 32 has a protrusion 33 provided on the outer periphery of the rotary shaft 6.
In the circumferential direction of the rotary shaft 6, and the engagement of the protrusion 33 with the pin 32 prevents the rotary shaft 6 from rotating in the direction in which the upper cone 7a is disengaged.
a is held in the engaged state.

Therefore, the container connector A ₀ does not fall off the corner fitting C, and the suspended container A ₁ can be safely moved.

The container A ₁ to which the container connecting tool A ₀ is connected is moved to above the lower side container A ₂ previously stacked, and the lower cones 7b are engaged with the corner metal fittings C at the four corners of the upper side of the lower side container A _2. When the container A ₁ is lowered so as to be inserted into the fitting hole H, when the lower cone 7b is inserted into the engagement hole H, the lower cone 7b is disengaged by contact with the inner circumference of the engagement hole H. Rotate towards position.

At this time, the spring 10 is elastically deformed. Further, the upper cone 7a rotates together with the rotating shaft 6, but the upper cone 7a rotates in the direction in which the area of engagement with the peripheral portion of the engagement hole H increases, and therefore the engagement is not released.

The protrusion 33 of the rotary shaft 6 is formed by the stopper 3
Since it rotates in the direction away from the pin 32 of No. 1,
2 does not hinder the rotation of the rotary shaft 6.

When the container A ₁ is lowered to a position where the flange 2 of the container connecting tool A ₀ is supported by the upper surface of the corner metal fitting C of the lower container A ₂ , the lower cone 7b is engaged with the engaging hole of the lower corner metal fitting C. After passing through H, the rotating shaft 6 is rotated by the restoring elasticity of the spring 10 and the lower cone 7b rotates toward the engaging position to engage with the peripheral portion of the engaging hole H. As shown in FIGS. 4 to 4, the upper and lower containers A ₁ and A ₂ are connected.

In the connecting operation of the containers A ₁ and A ₂ as described above, when the rotary shaft 6 rotates in the direction of disengaging the upper cone 7a, the cam projection 23 presses the pressing element 19 of the lever member 11. However, since the pressing amount is extremely small, the lever member 11 is held in a substantially horizontal neutral state by only slightly swinging.

Therefore, the operating portion 16 of the lever member 11 does not engage the engaging surface 27, and the lower cone 7b is not held in the disengaged state.
b can be securely engaged with the peripheral portion of the engagement hole H,
It is possible to reliably connect the upper and lower containers A ₁ and A ₂ .

When loading and unloading the upper container A ₁ , the hook f provided at the tip of the operating rod B is pulled down to the operating portion 16 of the lever member 11. When the operating portion 16 is pulled down, the wire 15 is pulled out and the lever body 1
2 swings around the fulcrum pin 20, and the pusher 19 at the other end of the lever main body 12 causes the inclined cam surface 23 of the upper cam projection 23 to move.
Press a. By the pressing of the inclined cam surface 23a, the rotary shaft 6 rotates in the direction in which the lower cone 7b is disengaged.

Further, when the wire 15 is pulled out to the position where the operating portion 16 is pulled out from the operating portion insertion hole 25, the wire 15 enters the wire insertion groove 26, and the operating portion 16 moves downward along the outer periphery of the flange 2. Move in the direction. As shown in FIG. 5, when the operation unit 16 is pulled down to a position where the wire 15 collides with the end of the wire insertion groove 26, the operation unit 1
The rear end surface of 6 engages with the engagement surface 27, and the engagement keeps the lever member 11 in a swinging state and the lower cone 7b in the disengaged state. Then, when the upper container A ₁ is pulled up, the lower protruding portion 3b and the lower cone 7b are pulled out from the engaging holes H of the lower corner metal fitting C, and the container connector A ₀ becomes the upper container A ₁
It is loaded with.

The container connecting tool A ₀ remaining in the upper container A ₁ pushes up the operating portion 16 to release the engagement with the engaging surface 27, and the spring 18 pulls the wire 15 and the operating portion 16 to move the lever. The member 11 is swung toward the neutral position, and the rotary shaft 6 is returned and rotated by the elastic force of the spring 10 to move the lower cone 7b.
To the engaged position.

After the return rotation of the lower cone 7b, a rotational force is applied to the lower cone 7b to rotate the upper cone 7a toward the disengagement position. When the upper cone 7a is returned to the disengaged position, the container connecting tool A ₀ descends by its own weight, the upper projecting portion 3a and the upper cone 7a slip out from the engaging hole H, and the container connecting tool is removed from the container A _1. Be done.

In the container connector shown in FIGS. 1 to 5, when the upper cone 7a is connected to the corner metal fittings C at the four corners of the lower surface of the suspended container A ₁ , the lower cone 7a is connected.
Since b is not held in the disengaged state, the upper and lower containers A ₁ and A ₂ can be reliably connected by the container connecting tool.

When the container connector is connected to the corner metal fitting C of the container which is suspended and supported, the stopper 31
Since the pin 32 provided on the upper surface of the rotary shaft 6 faces the protrusion 33 provided on the outer periphery of the rotary shaft 6 in the circumferential direction, the upper cone 7a is prevented from rotating in the disengaging direction.
It is possible to securely hold ₀ in the connected state, and to move the container A ₁ safely without the risk of dropping the container connecting tool when the suspended supported container A ₁ is moved.

Further, cones 7 provided at both ends of the rotary shaft 6
The cam projections a and 7b are displaced in the circumferential direction of the rotary shaft 6 so as to be disengaged when the rotary shaft 6 is rotated in different rotation directions, and are pushed by the pusher 19 when the lever member 11 swings. 23 is provided vertically, the wire insertion grooves 26 are formed above and below the opening end of the lever accommodating hole 5, and the engagement surfaces 27 are provided on the outer circumferences of the ends of the wire insertion grooves 26, respectively. A ₀ can be inverted upside down for safe use.

In the embodiment shown in FIGS. 1 to 3, the pressing member 19 is integrally provided on the lever member 11, but a roller rotatably supported may be used as the pressing member.

6 and 7 show another example of the lever member 11. The lever member 11 shown in FIGS. 6 (I) and (II) has a pusher 41 for pushing the cam projection 23, and can swing about a fulcrum pin 47 provided on both sides of the lever body 4.
The wire 42 is connected to one end of the wire 0, and the protrusion 43 fixed to the tip of the wire 42 is inserted into the guide hole 45 provided in the flanged operation portion 44, and one end is supported by the protrusion 43. The operation portion 44 is pressed against one end of the lever body 40 by the spring 46, and when the operation portion 44 is pulled down,
Only the operation part 44 is separated from one end of the lever body 40.

Lever member 11 shown in FIGS. 7 (I) and (II)
Is provided with a flanged operation portion 52 having a larger diameter than the shaft body 50 at one end of a cylindrical shaft body 50 provided with a fulcrum pin 51 at a substantially central portion in the longitudinal direction. The lever member 11 is swingably supported by being supported by pin holes 21 formed on both sides of the lever member 5.

In the lever member 11, the operating portion 5
Since 2 is integrally provided on the shaft body 50 and cannot be moved in the axial direction, the temporary fixing mechanism 24 shown in FIG. 1 cannot be adopted.

Therefore, the inclined cam surface 23a of the cam projection 23
A recess 53 is formed at the end of the shaft, and the other end of the shaft body 50 is engaged with the recess 53 to hold the lever member 11 in a swinging state and hold the lower cone 7b in a disengaged state. I am trying to do it.

FIG. 8 shows another example of the stopper mechanism 28 which holds the upper cone 7a in the engaged state. The stopper mechanism 28 has a stopper insertion hole 29 formed in the flange 2.
Is a square prism, and a stopper 60 composed of a round shaft is housed in the stopper insertion hole 29 so that its axis intersects with the axis of the rotary shaft 6, and a penetrating hole formed on the axis of the stopper 60. A pin 62 is inserted into the hole 61, one end of the pin 62 is inserted into the pin hole 30, and the other end is inserted into a vertically long support hole 63 formed in the inner periphery of the stopper insertion hole 29. There is.

As described above, the stopper insertion hole 29 is a square hole, and the stopper 60 composed of a round shaft is installed in the stopper insertion hole 29 so that its axis intersects with the axis of the rotary shaft 6. As a result, the stopper 60 moves up and down while rotating due to contact with the inner peripheral surface of the stopper insertion hole 29, so that the stopper 60 can always be smoothly moved in the vertical direction.

[0067]

As described above, according to the present invention, since the lower cone is not held in the disengaged state when the upper cone is engaged with the corner fitting, the upper and lower containers can be securely held. It is possible to provide a highly safe container connector that can be connected.

Further, since the upper cone and the lower cone are provided with a phase shift in the circumferential direction of the rotating shaft so as to be disengaged by the rotation of the rotating shaft in different directions, the engagement of each cone with respect to the peripheral portion of the engaging hole is increased. It can take a large mating area, and even when using the container connector upside down,
The upper cone can be firmly connected to the corner metal fittings of the suspended container, and can be used even if the container connecting tool is turned upside down.

Further, when the upper cone is engaged with the corner metal fitting of the suspended container, the pin provided on the stopper faces the protrusion formed on the outer periphery of the rotating shaft to disengage the upper cone. In order to prevent the rotating shaft from rotating, it is possible to securely hold the container connecting tool in the connected state, and there is no inconvenience that the container connecting tool will drop when the suspended container is moved. It can be moved safely.
