BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic handle used for assembling in a cardboard box for packing and the like, particularly to a handle which can be automatically assembled in a packing operation.

[0002]

2. Description of the Related Art When packing home appliances such as VTRs using a cardboard box, various handles are assembled and used in the packing cardboard box for the purpose of facilitating individual handling and transportation of the packing box. ing.

[0003] As a typical handle used for handling and transporting such a packing cardboard box, there are various straps which are attached so as to be able to be pulled out from the packing cardboard box. However, such straps require a lot of labor for connecting to the cardboard box to which the straps are attached, and it is difficult to store the straps once pulled out again in the cardboard box, so that they were pulled out. There has been an inconvenience that the straps are left hanging on the outer surface of the cardboard box.

From such a point, a plastic handle as shown in FIGS. 8 to 10 has recently been assembled and used in a packing cardboard box. This kind of handle can be easily and reliably packed by simply inserting and locking both sides of the handle into the mounting holes provided in the packing cardboard box due to the elasticity and flexibility of the synthetic resin material. In addition to having the feature that it can be assembled to the box, the unique elasticity of this handle makes the handle part always protrude from the surface of the packing cardboard box to the projecting side,
The handle can be easily and smoothly handled and handled using the handle, and has a feature that the cardboard box is securely pushed into the cardboard box while being deformed when stacked.

[0005]

However, the handle A shown in FIG. 8 has the handle A itself formed in a curved strip shape, and has both sides of the curved side facing each other. The locking projection piece a is provided facing the locking projection piece a. The locking projection piece a is inserted into the slit b provided in the box B while being deformed, and the locking projection piece a is inserted into the box B. Since the handle A is held on the box B by elastically returning the handle A, it is necessary to insert and lock the handle A one by one while elastically deforming the handle A one by one. In addition, since the insertion angles are different from each other, there is a disadvantage that a large-scale device having complicated operation contents is required to automatically assemble them by mechanical operation.

Further, since the handle A of this kind has a curved portion having a flexible elasticity, the handle A is deformed when it is caught by a mechanical operation and is assembled to the box B, so that it is always deformed. The L dimension tends to be different, and it is difficult to smoothly insert the locking projection a into the slit b of the box B by mechanical operation. Also, the variation in L dimension of such a handle A is
Since the handle A has a curved portion having a flexible elasticity, it also occurs as a shrinkage strain at the time of forming the handle A, and the shrinkage of the formed handle A changes with time, and the handle A is stacked during storage. This is caused by deformation or the like, and makes accurate catching by mechanical operation of the handle A and reliable insertion and locking of the box B into the slit b difficult.

[0007] In view of the inconvenience of such a conventional handle, the present invention requires that the length of the handle itself be large even when the handle is formed.
It is another object of the present invention to provide a handle that can be stably maintained during storage or handling operations, and that can be easily, smoothly, and accurately assembled by mechanical operation of the handle box.

[0008]

The handle according to the present invention achieves the above-mentioned object, and the handle A is provided with a long plate-shaped seat plate 1 and a longitudinal direction of the seat plate 1. A slit formed in the width direction of the seat plate portion 1 as an integral plastic molded product comprising an elastically deformable grip piece portion 2 that stands up from one side and extends while bending to the other side. 3 is attached to the tip of the grip piece 2 which is bent and inserted from the side opening 3a of the slit 3 and is inserted into the grip piece 2
The locking piece 4 is provided so as to engage with the surface of the seat plate portion 1 of the slit edge 3b on the side opposite to the side where is provided.

[0009]

The handle A according to the present invention has an elastically deformable grip piece 2 with one end thereof standing upright from the seat plate 1 and the other end of the grip piece 2 as a free end. In addition, since the seat plate 1 is inserted and locked in the slit 3 of the seat plate 1 so as to be elastically deformable, the length of the seat plate 1, which is the length of the handle A, may be reduced when the handle A is assembled. It works to keep it even.

[0010]

The grip piece 2 is inclined toward the front end thereof so as to gradually separate from the seat plate 1 facing the tip end, and the grip piece 2 is located on the side of the seat plate 1 from the inclined top 2c. And a downwardly inclined portion 2d bent close to
The lower end of the downwardly inclined portion 2d is an upright portion 2e orthogonal to the locking piece 4 provided at the free end 2a, and is sufficiently elastically deformable at the bent portion 2b. The configuration is flexible. The locking piece 4 at the tip of the gripping piece 2 is provided in a shape orthogonal to the upright portion 2e over the width side of the gripping piece 2 having a strip shape. The grip 2 protrudes from the band-shaped portion of the portion 2 e in the length direction of the grip piece 2.

The grip piece 2 which stands upright from the seat plate 1 has a good clipping property when operating the machine and also has good grip characteristics when used for gripping. It is preferable that the locking piece 4 has the same width as the width of the slit 3 from the viewpoint that the locking piece 4 has a reasonable locking property with respect to the slit 3. Since it is necessary to provide the slit 3 to be locked, it is preferable that the slit 3 is provided on one side of the width side of the seat body 1, that is, on a side where the side opening 3 a of the slit 3 is provided. The grip piece 2 which is integrally erected from the seat plate 1 is erected from a position where the contact plate 1a is left on one side D in the length direction of the seat plate 1.
