Description

Handle mounting structure of plastic molded case

The present invention relates to a handle mounting structure for a plastic case composed of two pieces connected by a hinge. Background art

Some plastic molded cases are fitted with handles for easy carrying. These handles can be broadly classified into two types: the movable type, which has a movable mechanism, and the fixed type, as functions of the handle itself.

The movable eight handle improves unnecessary protrusion of the handle when not being carried, and has features that are superior to the fixed one.

For example, there are a movable handle having a side-down type in which the handle is turned sideways, and a movable handle in which the left and right sides of the handle are slid to form a handle.

When using the handle, the sideways handle must be raised from the body in order to reach the handle. On the other hand, with a sliding handle, it is only necessary to handle the handle because the handle is already formed. Therefore, for convenience, the sliding handle is superior to the side-down handle.

The sliding handle is further provided on one side of the two-piece case body (for example, Registered Utility Model No. 3005683), and the two pieces are combined to completely close the case. Some can function as a handle when they are in place.

However, the handle provided on one side of the case requires a plurality of separate parts for attaching the handle to the case, and the number of manufacturing steps for the plastic molded case increases because the handle is locked to the case with parts. Had risen.

Therefore, a case was considered in which a separate member was unnecessary and only the handle portion was attached. I However, this handle was easily detached from the case when the case was open.

An object of the present invention is to provide a mounting structure in which a separate function is unnecessary and a function as a handle can be obtained by simply mounting the handle on one side of a case. Disclosure of the invention

In order to solve the above-mentioned problems, a handle mounting structure for a plastic molded case according to the present invention includes a handle post opposed to a top of a peripheral edge of a plastic molded case main body at a predetermined interval. A tongue piece is erected from the top of the peripheral edge of the main body, extends in parallel with the top of the peripheral edge, and a flange portion is protruded downward at the end thereof. Protrusions are provided at corresponding positions so that a gap is formed between the tongue and the flange, and at least one side of a space formed between the tongue piece and the peripheral top is closed. The handle is provided with an opening for preventing the escape of the handle at the top of the peripheral edge corresponding to the one part. On the other hand, locking projections are provided at both ends of the handle, and the locking projection is projected downward. A guide projection is provided so as to be slidably fitted into the escape preventing groove. The handle end configured as described above is guided into the handle bost, and the handle is suspended when the handle is suspended. It is characterized in that the locking projection at the handle end is configured to be loosely fitted by the flange and the protruding sound [5].

The tongue piece and the top edge of the case body are integrally connected by a vertical plate that is erected between the rising end of the tongue piece and the handle escape prevention groove at the top of the case body periphery. The tongue can be configured to prevent outward bending.

Horizontal guide projections are provided on both sides of the locking projections provided on both ends of the handle, and the open side of the handle post, which protrudes from the handle body closing side at the top of the case body and the top of the case lid. Horizontal guide on the inner surface with side plate for closing By providing a groove and abutting the horizontal guide protrusion piece against the slide guide member, the movement of the handle end portion in the handle post when the handle is suspended is smooth. A rim is protruded along the open side edge of the tongue piece, and a fitting groove for accommodating the rim is also provided on the side plate on the lid, so that the open side of the handle boss and the lid are provided. Adhesion with the body top side plate can be enhanced. BRIEF DESCRIPTION OF THE FIGURES
