Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to electronic devices, musical instruments, tools, etc., which are composed of a hollow double-walled case body and a plate-shaped lid body.
This relates to plastic cases for storing various items.

[Prior Art] A plastic case which forms a storage part by closing a case body and a lid body and stores various articles such as electronic devices, musical instruments, tools, etc.
This is already known as described in Japanese Patent No. 18748.

[Problems to be solved by the invention] Generally, a plastic case for storing this type of item has a lid connected to the case body by a hinge, and the lid is connected to the case body on the opening side of the case. It has a latch to hold it closed.

By the way, especially in portable cases, the wall thickness of the case tends to be thinner because it is desired to be lightweight, but cases formed in this way tend to be easily deformed and the latch has a tongue-like shape. In cases where the case is attached to the wall of the case, even if the case is closed and the latch is engaged, there is a risk that the latch may come off due to deformation of the case, causing the case to open inadvertently.

Therefore, even if the lid of the latch is plate-shaped and lightweight, the latch on the case body side is passed through the latch hole on the lid side and then folded back to engage the locking step on the case body. By locking the case, even if the case is deformed, there is no risk that the latch will come off and the case will open accidentally, especially for electronic devices, musical instruments,
The object of the present invention is to provide a plastic case that is excellent for storing, safely carrying, and storing various articles such as tools.

[Means for Solving the Problems] The plastic case according to the present invention is a plastic case composed of a hollow double-walled case body and a plate-shaped lid covering the opening surface of the case body, and includes:
A mounting piece that can be raised and lowered freely through a hinge is formed on the rear wall end face of the case body, and a latch that can be raised and lowered freely through a hinge is formed on the front wall end face of the case body, and a mounting piece is integrally formed on the lower part of the front wall end face where the latch is formed. forms a locking step for the latch, and the lid also has an engagement hole for the mounting piece at its rear end, a latch hole for passing the latch at its front end, and a mounting hole on the case body side. The latch is attached to the engaging hole of the lid, and the latch on the case body side is passed through the latch hole of the lid, turned outward, and locked to the locking step.

[Function] The case body and the lid body are separate bodies, and when the lid body is placed over the opening of the case body, attach the mounting piece on the case body side to the rear end of the lid body, and attach the latch hole at the front end of the lid body. put it back through the latch,
It locks onto the locking step on the case body.

In this way, when the lid is closed and latched, the latch on the main body is passed through the latch hole in the lid, then folded back and latched to the main body, so the case body cannot be moved inside or outside. Even if it is considerably deformed,
The latch does not come off, so there is no risk of the case opening accidentally.

[Example] An embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a case body, and this case body 1 has a hollow double-walled structure with an open top surface. 2
is a plate-shaped lid, and this lid 2 covers the opening surface of the case body 1. Above case body 1
Attachment pieces 3, 3 are integrally formed on the end face of the rear wall of the case body 1, and a latch 4 is integrally formed on the end face of the front wall of the case body 1. The mounting piece 3 is formed integrally with the opening surface of the case body 1 via a hinge 5 so as to be able to rise and fall freely.
A protrusion 6 is provided for attachment to. The latch 4 connects the press plate 7 and the locking part 8 with a hinge 9 in a flexible manner, and further connects the press plate 7 with the hinge 1.
It is integrated with the case body 1 so as to be able to bend freely by the latch 4, and locking steps 11, 11 of the locking portion 8 of the latch 4 are formed on the outer side of the end surface of the case body 1. A finger rest concave portion 12 is formed between the stop portions 11, 11. Positioning protrusions 13, 13 are formed on the left and right edges of the opening surface of the case body 1.

The lid body 2 has a projection 6 of the mounting piece 3, 3 at one end thereof.
A latch hole 15 through which the latch 4 is inserted is formed at the other end, and a positioning protrusion 1 is formed at the left and right ends.
Notches 16, 16 are formed to engage with the holes 3, 13.

Note that a handheld handle 17 is integrally formed or attached to the case body 1 via hinges 18, 18. This handbag handle 17 has hinge 1
8 and 18, it can be folded freely.

The case body 1 and the lid body 2 are made of thermoplastic plastic, and the case body 1 is manufactured by blow molding, and the lid body 2 is manufactured by punching and pressing.

In the case configured as described above, in order to cover and fix the lid body 2 on the opening surface of the case body 1,
The lid body 2 is closed from the rear end side to the front end side, so that the notches 16, 16 are engaged with the protrusions 13, 13. Then, the mounting pieces 3, 3 are pushed down toward the opening side, their protrusions 6, 6 are engaged with the engagement holes 14, 14, and then the latch 4 is passed through the latch hole 15 of the lid body 2, folded back to the outside, and then The locking part 8 is connected to the locking step part 1
1 and 11, both ends of the lid body 2 are locked and fixed by the mounting pieces 3, 3 and the latch 4.

To remove the lid 2 from the case body 1, first remove the latch 4 and open the lid 2 in the reverse order of the installation procedure described above.

Note that the means for attaching the lid 2 to the mounting pieces 3, 3 is to make holes in the mounting pieces 3, 3 as well.
It is also possible to fix the lid body 2 with rivets or screws. If the lid 2 is made of a transparent plastic plate such as acrylic or polyvinyl chloride, the stored items can be visually recognized even when the lid 2 is closed.

[Effects of the invention] Since the invention has the above-mentioned technical means and works, even if the lid of the case is plate-shaped and lightweight, the latch on the case body side By passing the latch through the latch hole on the lid side, folding it back, and locking it to the locking step on the case body, even if the case is deformed, there is no risk that the latch will come off and the case will open accidentally. In particular, it is possible to obtain a plastic case that is excellent for storing, safely carrying, and storing various articles such as electronic devices, musical instruments, and tools.
