[0001]

[Technical field to which the device belongs]

 The present application relates to a lifting jig used when a resin box is used to store materials, parts, etc. in a factory, a warehouse, etc., when the box is moved.

[0002]

[Problems to be solved by the device]

 For example, the finished small parts during pressing work are put in a box of an appropriate size and wait for the next process, but when moving, if it is obviously small amount and light weight, it can be carried by one person. There is no particular problem. However, when heavier than expected, it was also seen that labor accidents such as a back injury occur.

[0003]

[Means for Solving the Problems]

 In order to solve the above problems, in the present application, a lifting jig is used that securely holds a resin component box with a simple operation and does not disengage the grip even while the hoist is moving. Solves the problem.

[0004]

[Prior art]

 Conventionally, the parts box is too heavy for one person to move alone, or if the weight is not clear, use a rope with hooks at both ends as shown in Fig. 8 and hang it on the handles on both sides of the box, However, the rope connected to the hook on the handle is loose until the hoist winds up, and the hook may come off before the rope is tensioned, making it difficult to handle. Dangerous conditions could occur.

[0005]

[Form of actual state of invention]

 Therefore, the present application mainly discloses a jig for lifting a resin component box by a simple operation. The resin box is formed by projecting a wide width around the opening to improve the strength of the box itself and to improve stability when stacked. There is. There is also a handle with a horizontally long opening at the upper position on both sides to allow the hand to be put in when carrying. Whichever type is used, ribs R are provided outwardly around the upper end. In the present application, by utilizing this rib R, the locking hooks are simultaneously rotated from both sides of the box to abut against the lower side surface of the rib R, and at the same time as this rotation action, the inner surface of the box is Insert the inner support piece 5 that extends downward so that the side of the resin box is sandwiched at the tip of the hook so that the resin box is deformed by the pressure applied from the outside of the hook, and the hook is rib R when lifted. To prevent disengagement. Therefore, a rib that protrudes between the tip of the locking hook 7 and the inner support piece 5 is sandwiched, and the weight inside the box, that is, the lifting weight, provides a stable pressing force from the side surface of the locking hook. To be adopted.

The above-described operation is such that the locking hooks 7 are rotatably provided at both ends, and the operating members 4 fixedly provided with the inner support pieces 5 at both ends are pushed up, whereby the locking hooks 7 are continuously provided. The elongated hole 8 provided in the L-shaped rotating member 9 is controlled by the guide shafts 3 at both ends of the hanging member 2 at the upper position so that the locking hook 7 is rotated outward. Then, in this state, position the hoist connected to the suspension ring 1 of the hanging member 2 onto the specified box and release the hand attached to the operating member 4, causing the operating member 4 to fall due to its own weight and the inner support piece. 5 is provided along the inside of the box, and at the same time, the locking hook 7 is rotated to come into contact with the vicinity of the rib R. If the hoist's hoisting force is applied in this state, the rib R can be securely held and the hoist can be safely hoisted.

【Example】

 An example of the present application will be described. A strip of steel of approximately the same length as between the side walls of the box is piled up, the shafts 6 are bridged at both ends, and inner fulcrums 5 are placed inside the shafts 6, respectively. Since the inner support side is arranged in the direction orthogonal to the steel strip, it is welded to the tip of the inner support piece 51 sandwiched between the steel strips, and the lower ends are bent inward and face each other. , The upper end is bent outward at a right angle. This downward bending is for smooth insertion when it is inserted into the component box, and the upward bending is to prevent the present application from falling to the left or right when placed on the rib of the box. belongs to. In addition, the inner support member 51 serves as a spacer of polymerized steel strip and maintains a predetermined distance on the shaft 6. A rotating member 9 is arranged on both end shafts 6 of the operation member 4 having the above-mentioned configuration.

The rotating member 9 is provided with a locking hook portion 7 downward with the shaft support hole 91 as the center. Since it is desirable for the locking hook 7 to come into contact with the rib over a wide range, the locking hook 7 is bent substantially at a right angle by a plate material so that the tip of the hook is arranged parallel to the rib. Therefore, both locking hooks 7 are arranged symmetrically with the ends of the hooks facing each other. Upward from the shaft support hole 91, inverted L-shaped plate members are arranged in a row in a direction orthogonal to the plate member of the locking hook 7 so as to be symmetrical to the left and right, and a lateral elongated hole 8 is formed at the tip. Set up. A guide shaft 3 of a suspending member 2 described below passes through the elongated hole 8 and is arranged in a freely movable state.

A suspending member 2 is provided above the operating member 4. The hanging member 2 is also made by superposing two strips of steel at a predetermined interval, and the hanging ring 1 is arranged as a spacer in the center part, and the L-shaped part of the rotating member 9 is placed between both ends of the overlapping part. The part where the long hole 8 is arranged is clamped. The guide shaft 3 is fixed between the strip steels by penetrating the overlapped elongated hole and restricts the movement of the rotating member 9. As shown in FIG. 4, the guide shaft 3 is located at the inner end of the elongated hole 8 when the locking hook 7 is closed and in contact with the inner support piece 5, and when it is at the outer end, This is when the locking hook 7 is open. A stopper 10 provided with an operation piece bent in an L shape is provided on both sides of the suspension ring of the suspension material 2 so as to pivot between the overlapped steel strips, and the locking hook 7 is closed. By making contact with the end of the L-shaped portion of the rotating member 9 in the state, the movement thereof is restricted so that the closed state can be maintained.

As another embodiment, as shown in FIG. 6, pipe members are used for the operating member 4 and the hanging member 2, and U-shaped shaft frames 22 and 42 are fixed to both ends, By bridging the shaft in the meantime, the elongated holes 8 provided in the rotating member 9 are provided with an upward slope toward the inside, respectively, so that the rotation of the rotating member 9 can be smoothly rotated. A notch 92 is provided at the L-shaped tip of the material 9, and a pin 11 that can be inserted and removed is provided at the suspension member. When the pin 11 is inserted, it abuts the notch 92 to limit the rotation of the rotating member 9, The configuration in which the locking hook is maintained in the closed state is suitable when the lifting weight is large, and has the same effect as that of the first embodiment.

Further, as shown in FIG. 7, by configuring the intermediate portion between the operating member 4 and the suspending member 2 so that the length can be freely changed, it becomes possible to cope with various boxes having different sizes.

In use of the present application, the present invention suspended by a hoist is positioned at the upper part of the parts box, and the operating member 4 is pushed up. Then, while the long hole 8 of the rotating member 9 is restricted in movement by the guide shaft 3, the L-shaped member rotates about the shaft 6 as a fulcrum, and the continuous locking hooks 7 move left and right. Open. In that state, insert the inner support piece 5 along the inner wall of the parts box, and release the hand attached to the operating material 4 at the position where the open locking hook 7 seems to engage with the rib of the parts box. The clasp 7 is closed, and the rib is sandwiched between the end of the clasp 7 and the inner support piece 5 so that the rib can be lifted. When this suspension load is applied, the force with which the locking hook portion 7 presses the rib increases in proportion to the weight of the component box. Also, when the guide shaft 3 is located at the inner end of the slot 8, the locking hook 7 and the inner support piece 5 are in contact with each other. Since it tries to rotate in the direction of biting into the box, it can be firmly held together with the inner support piece 5 that supports it from the inside of the box.

[0013]

[Effect of device]

 As described above, by using the present invention, it is possible to easily lift and move the resin-made component box, and the operation thereof is simple and reliable operation can be expected.
