Description

[Detailed description of the invention] Industrial application field The present invention is a plastic device with a handle, which consists of a pair of halves, such as a case body and a lid, in which one half can be opened and closed with respect to the other half. It's about the case.

BACKGROUND ART Conventionally, plastic cases with handles that can store and carry various articles have been widely used, and this type of plastic case is described in, for example, Japanese Utility Model Publication No. 46-35409.

Problems to be Solved by the Invention The handle of the plastic case described in the above publication can be rotated freely by simply fitting the protrusions formed at both ends of the shaft into the fitting holes on the case side. Since the handle is attached, there is a risk that the handle may come off if there is even a slight distortion in the fitting hole of the handle or the case, such as when storing and carrying a heavy object.

In addition, in this handle attachment structure, in order to reliably prevent the handle from coming off, the protrusion of the handle may be made long, but in this case, attachment of the handle is not easy.

Therefore, in view of the problems of the conventional products, the present invention aims to provide a plastic case with a handle that allows the handle to be easily attached to the case and prevents the handle from accidentally coming off. This is the purpose.

Means for Solving the Problems The present invention has the following technical means for achieving the above object. In other words, it consists of a pair of halves, one half of which can be opened and closed, the other half having a handle and legs at both ends, and one leg having a tapered bulge. and a handle having a protrusion having a flat bulge on the other leg,
One half is formed with a handle attachment part having a pair of fitting holes that are larger than the diameter of the protrusion of the handle and smaller than the diameter of the bulge, and the protrusion having the tapered bulge of the handle is fitted into one of the halves. A plastic case with a handle, characterized in that a handle is attached by fitting into a fitting hole and then fitting a protrusion having a flat bulge into the other fitting hole.

That is.

In the plastic case with a handle according to the present invention, in order to attach the handle to the case, first fit the protrusion having the tapered bulge of the handle into the fitting hole on one side of the handle attachment part, as described above. However, since this bulging portion is tapered, it is easy to press fit into the fitting hole. When the tapered bulge is press-fitted into the fitting hole, the protrusion is rotatable in the fitting hole and is also slidable to some extent in the axial direction. Therefore, when fitting the other protrusion with a flat bulge into the fitting hole, by shifting the handle in that direction, the flat bulge can be fitted with just a slight deformation of the handle. Pressure can be applied to the hole, and the protrusion is rotatably supported in the fitting hole.

The handle attached in this way has bulges on both of its protrusions, and the fitting hole of the handle attachment part has a smaller diameter than the bulges, so the bulges are larger than the protrusions of the handle. Provides a reliable stop. Therefore, even when carrying heavy items stored in the case, there is no fear that the handle will come off, making it safe.

Embodiment An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a handle, and the handle 1 is formed into a substantially U-shape having a handle portion 2 and legs 3, 3 at both ends. Both legs 3 of the handle 1,
3 has protrusions 4, 4' protruding from the inside of its ends, one of the protrusions 4 has a tapered bulge 5 at its tip, and the other protrusion 4' has a flat bulge. 5' are formed respectively. The tapered bulge 5 has a flat bulge 5' due to its shape.
It is longer than . Reference numeral 6 denotes one half of the plastic case, and a handle mounting portion 7 is formed on the upper surface of the plastic case, and the handle 1 is fitted onto both end surfaces of the handle mounting portion 7. It has matching holes 8, 8'. The above-mentioned one half 6 has a hollow double wall structure, and the handle attachment part 7 is formed to bulge above the weld part 6a where the outer wall is welded to the inner wall, and is hollow and has a handle attachment part. The strength has been improved. The other half 9 also has a hollow double wall structure, and the one half 6
The upper mating surfaces of the two halves 9 are each formed with engaging step portions 10 and 11 such that the one half 6 side engages with the bottom of the other half 9 side, and this configuration This prevents the mating surfaces from deforming during transportation. Note that the handle 1 is also made of plastic. One half 6 and the other half 9 are
For example, they are a case body and a lid body, and one half 6 of the pair of halves is the other half 9.
can be opened and closed freely. 12 and 12 are latches.

To attach the handle 1 to the handle attachment part 7, first press fit the tapered bulge 5 of the handle 1 into one fitting hole 8, fit the protrusion 4, and then attach the handle 1. Pull it in the other direction to shift it to one side, press fit the flat bulge 5' into the other fitting hole 8 of the handle attachment part 7, and fit the protrusion 4'.
The handle 1 is rotatably attached to the handle attachment part 7.

By the way, in the handle 1 attached to the handle attachment part 7 as described above, since both protrusions 4 and 4' have bulges 5 and 5', the handle 1 is not subjected to a large load in the axial direction. Even if it is received, the protrusions 4, 4'
will not come off from the fitting holes 8, 8'. Also,
When attaching the handle 1, the tapered bulge 5 is first press-fitted into the fitting hole 8, and since its shape is tapered and elongated, attachment is easy. The other bulge 5' is flat and short, so
When it is press-fitted into the fitting hole 8', the handle 1 only needs to be deformed very slightly, and its installation is easy.

Effects of the invention The present invention has the above-mentioned technical means and works, so the handle can be easily attached to the case, and the attached handle cannot be accidentally pulled out. Therefore, it is possible to obtain effects such as safety even when storing and carrying heavy objects.
