Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging tool used when lifting a box with a crane or the like.

[0002]

[Prior art]

 Conventionally, as a suspending tool used for moving a box such as a container using a crane or the like, as shown in FIG. 4, a handle hole Wa of a plastic container W which is a box is provided at both ends of a long belt 101. It is known to attach a hook 102 for hanging on.

When a container W stacked in three stages is lifted by a crane using this lifting tool, as shown in the same figure, the belt 102 with the hook 102 hooked in the handle hole Wa of the container W at the lowermost stage is used. Make sure to hang the hook 103 of the crane on 101.

[0004]

[Problems to be solved by the device]

 In the conventional lifting device described above, when the containers stacked in several stages are lifted, the belts only push the both sides of the container inward, so even if it is stable in the left-right direction. It becomes very unstable in the front-rear direction, and when the heavy container is lifted, the pressing force applied to both sides of the container by the belt becomes too strong, which may deform the container and adversely affect the contents. Yes, especially when lifting something like a cardboard box instead of a plastic container, the deformation is remarkable, and it may be difficult to actually lift it.In addition, pull the belt upward with the hook in the handle hole of the container. Otherwise, the hook will come off, and you will have to hang the crane hook on the belt while pulling the belt upward.

[0005]

Means for Solving the Problems In order to solve the above problems, the present invention connects one ends of a pair of arms provided with an opening / closing lever so that the arms can be opened and closed, and urges the pair of arms to a closed state. A spring is provided, and a stopper member that regulates the opening and closing angle is provided. Further, a hook arm is attached to the other end of the pair of arms, and a lifting hook is provided at the lower part of the hook arm, and an upper part thereof is provided. Has a fall prevention hook.

Further, in the present invention, in the above-mentioned hanging device, it is possible to provide a hook guide on the upper part of the hook arm and on the upper side of the fall prevention hook so as to come into contact with the upper surface of the box.

[0007]

[Action]

 Open the pair of arms with the open / close lever, align the hook arms with the sides of the box, and then release the open / close lever to return the pair of arms to the closed state by the biasing force of the spring. Locks the lowermost box, the fall prevention hook locks the uppermost box, and the box is attached to the hanging device. Also, the hook guide provided on the upper side of the fall prevention hook is pressed against the helicopter of the uppermost box when attaching the box to the hanging tool so that the hook arm is in the vertical state. Make it easier to set the lifting hooks.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a front view of a suspender according to the present invention with a box attached thereto, FIG. 2 is a perspective view of a main part of the suspender, and FIG. 3 is a plan view of FIG.

The suspender 1 is configured such that one end of a pair of arms 2 and 2 is openably and closably connected via a pivot bush 5 which is fixed to a bolt 3 with a nut 4, and one side surface of each arm 2 and 2 is opened and closed. The levers 6 and 7 are fixed by welding, and a torsion spring 8 that biases the arms 2 and 2 in a closed state is provided between the arms 2 and 2. The pivot bush 5 of the bolt 3 is provided with a bracket 10 as a stopper member between the arms 2 and 2 via washers 11 and 11. The bracket 10 is formed at both ends of the bracket 10 at one end of the arms 2 and 2. By contacting the bent portions 2a, 2a, the opening / closing angle of the arms 2, 2 is regulated. A hook hole 10a for hooking a hook of a crane is formed on the upper end of the bracket 10.

Hook arms 14 and 14 are vertically provided at the other ends of the arms 2 and 2, and a lower portion of the hook arms 14 and 14 is a lifting hook that can be hooked in a handle hole W1a of a container W1 at the lowermost stage. 15 and 15 are provided to face each other, and hooks for preventing fall 16 and 16 that engage with the handle hole W3a of the uppermost container W3 are provided on the upper portions of the hook arms 14 and 14 so as to face each other. Hook guides 17, 17 integrally formed with the hooks 16, 16 are similarly provided on the upper sides of the hooks 16, 16.

When the three-tiered containers W1 to W3 are hoisted by the hooks of the crane using the hoisting tool 1 configured as described above, after hooking the hook of the crane to the hole 10a of the bracket 10, The open / close levers 6 and 7 are grasped to open the pair of arms 2 and 2 against the biasing force of the spring 8. At this time, since the open / close levers 6 and 7 are located near the hook of the crane and can be operated with one hand, operability is improved. The open angles of the arms 2 and 2 are restricted by the lower ends of the bent portions 2a and 2a of the arms 2 and 2 coming into contact with the bracket 10.

In this state, after the hoisting hooks 15 and 15 of the hook arms 14 and 14 are aligned so as to be positioned on the side of the handle hole W1a of the lowermost container W1, the helicopter of the uppermost container W3 is positioned. By pressing the hook guides 17 and 17, the hook arms 14 and 14 are kept in a vertical state. Therefore, when the hands are released from the opening / closing levers 6 and 7, the restoring force of the spring 8 causes the pair of arms 2 and 2 to move. After returning to the closed state, the lifting hooks 15 and 15 are inserted into and hooked on the handle hole W1a of the container W1 at the lowermost stage.

At the same time, at this time, the upper ends of the bent portions 2a, 2a of the arms 2, 2 contact the bracket 10 to regulate the closing angle of the arms 2, 2 and crush the containers W1 to W3. It is prevented from being deformed. Further, the fall prevention hooks 16, 16 of the hook arms 14, 14 are fitted in the handle holes W3a of the uppermost container W3, and when the containers W1 to W3 are lifted, the container W1 is shaken in the front-rear direction. ~ W3 is prevented from collapsing.

In the above embodiment, the fall prevention hook and the example in which the guide is fixed to the hook arm have been described, but the stacking height can be increased by providing the hook arm vertically movable. Or, even boxes with different heights can be hung, which improves versatility.

[0015]

[Effect of device]

 As described above, according to the present invention, one end of a pair of arms provided with an opening / closing lever is connected so as to be able to open and close, and a spring for biasing the arm in a closed state is provided between the pair of arms. At the same time, a stopper member that regulates the opening and closing angle is provided.Furthermore, a hook arm is attached to the other end of the pair of arms, a lifting hook is provided at the bottom of this hook arm, and a fall prevention hook is provided at the top. Since it is provided, the boxes stacked in several stages can be lifted in a stable state, the deformation of the boxes is not caused, the operability is improved, and the workability is improved.

Further, in the above-mentioned hanging device, since the hook guide which comes into contact with the upper surface (edge) of the box is provided above the hook for preventing the hook arm from collapsing, the hook arm for hanging the hook arm can be hooked. The vertical state of can be easily secured, and the workability is further improved.
