Description

[Detailed description of the invention] [Industrial application field] This invention has a window in the case body or lid that is covered with a plate-like transparent cover, and the items stored in the case can be checked through the window. The present invention relates to a plastic case with a window, and more particularly to a structure for attaching a plate-like cover to the edge of the window.

[Conventional technology]

Conventional plastic cases with windows of this type are disclosed in Japanese Patent Laid-Open No. 59-199478 and Japanese Utility Model Publication No. 61-5130.

Among the above conventional examples, the structure of the joint portion between the window and the cover shown in the former (Japanese Patent Application Laid-Open No. 59-199478) is as shown in FIG. An edge c is provided, the edge of the cover d placed on the edge c is pressed by the frame e, and a pin f protruding from the frame e is passed through the cover d and inserted into the pin hole b. By fitting, the cover d is fixed to the window side.

The latter (publication of Utility Model Publication No. 61-5130) is designed as shown in Figure 7, with an edge h provided on the inside of the window g, and an edge h provided opposite to this edge h. The cover d is attached to the window side by fitting the edge portion of the cover d into the groove between the protrusions i.

[Problem that the invention attempts to solve]

Among the above conventional examples, in the former one, the cover d is firmly attached to the window a, but on the other hand,
Since the frame e is required as a separate member from the case and the cover, the number of parts and the number of assembly steps increase, which is disadvantageous in terms of cost.

In addition, in the case of the latter, a separate member is not required as in the former, but since the cover only engages with a groove provided on the inside of the window, the holding of the cover d is unstable. In some cases, the cover d would fall off the window g due to slight deformation.

[Means and actions for solving problems]

The present invention was developed in consideration of the above points, and it is possible to firmly attach a cover to a window without using a separate member such as a frame, and it can be installed more easily without coming off easily. The object of the present invention is to provide a plastic case with a window, which has a window covered with a plate-like cover on the main body or lid of the case, and a frame on the inside of the window. At the same time, grooves are formed in this edge and a plurality of opposing protrusions are provided in the circumferential direction of the window, and a cutout is provided in a portion of the edge opposite to the protrusion, and a groove is formed in the edge of the protrusion. The cover is attached to the window by protruding a pin in the part facing this cutout and inserting the edge of the cover into the groove between the edge and the protrusion. The inserted part is locked with a pin, and the cover is firmly attached to the window.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 5.

In the figure, reference numeral 1 denotes a plastic case, and the plastic case 1 consists of a main body 2 and a lid 3, one side of which is connected by a hinge 4. The main body 2 and the lid 3 are formed into a hollow double wall structure by blow molding.

The lid body 3 is provided with a window 5, and this window 5 is covered with a transparent cover 6. On the inside of the window 5, an edge 7 that is stepped and lowered with respect to the outer surface of the lid 3 protrudes over its entire circumference. Further, on the outer surface side of the lid body 3 from the edge 7, a plurality of projecting pieces 9 forming grooves 8 between the edge 7 and the upper surface of the edge 7 are provided in the circumferential direction of the window 5.

A cutout 10 is provided in the edge 7 at a portion facing the protruding piece 9, and a pin 11 is provided protruding from the back side of the protruding piece 9.

A hole 12 into which a pin 11 provided on the protruding piece 9 fits is provided at the edge of the cover 6.

In the above configuration, the cover 6 covers the edge 7 of the window 5.
At the same time, the edge part of this is inserted into the groove 8 between the edge 7 and the protruding piece 9, and the hole 12 of this is inserted into the groove 8 between the edge part 7 and the protruding piece 9.
It is attached to the window 5 by engaging a pin 11 protruding from the back side of the window.

At this time, the edge part of the cover 6 is inserted into the groove 8 over the pin 11, but the part where the edge part 7 of the window 5 faces the protruding piece 9 from which the pin 11 is protruded becomes the cutout part 10. Therefore, the edge part of the cover 6 in this part is deformed by the pin 11 without being obstructed by the edge part 7, and the hole 12 in the edge part of the cover 6 is deformed by the pin 11.
easily engages with pin 11.

The cover 6 attached to the window 5 in the above state is attached without being easily detached by engagement with the pin 11.

In the above embodiment, the pin 1 is attached to the edge of the cover 6.
1 is provided, but this hole 12 is not necessarily required. Even if this hole 12 is not present,
As shown in FIG. 3, the edge portion of the cover 6' is pressed and deformed by the pin 11, and has a locking effect almost similar to pin hole engagement.

[Effect of idea]

According to the present invention, the cover 6 can be firmly attached to the window 5 without using a separate member such as a frame, and it will not come off easily, and furthermore, the installation work is not particularly difficult and has good workability. Can be installed.
