Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to improvements in opening/closing devices for various storage case bodies.

(Background of the invention) In this type of storage case body, the inventors of the present invention have devised an opening/closing device shown in Japanese Utility Model Publication No. 54-9071.

As shown in FIG. 6, this opening/closing device has a claw-like locking piece b protruding from the opening of the case body a, and can be engaged with and detached from the claw-like locking piece b at the opening end of the lid body c. It has a structure in which a protruding tongue piece e having a locking hole d is provided.

However, since the tongue piece e is made of an elastic material and is formed into a flat plate shape, it bends in a curved shape when it is locked to the claw-like locking piece b, making it impossible to perform a smooth engagement operation.
Also, when removing the tongue e from the claw-like locking piece b, if you hook your finger on the tip, it will curve and press the claw-like locking piece b with your other finger to fit into the locking hole d. There were problems such as it being difficult to remove without using it.

(Purpose of the invention) In order to eliminate such problems, this invention
To provide an opening/closing device for a storage case body, which aims to enable easy opening/closing operations by smoothly engaging and disengaging a claw-like locking piece without bending a locking hole portion provided in a tongue piece. It is something.

(Structure of the invention) In order to achieve the above object, the opening/closing device of the storage case body of the present invention has a claw-like locking piece protruding from the opening end of either the case body or the lid body, and the other opening. A storage case comprising a tongue piece made of an elastic material such as rubber that protrudes from the end in correspondence with the claw-like locking piece, and a locking hole that can be engaged with and detached from the claw-like locking piece in the tongue piece. In the body opening/closing device, a peripheral wall of an appropriate height is protruded from the surface side periphery of the tongue piece from the tip to the base end so as to surround the locking hole, and the tongue piece is locked by this peripheral wall. The shape of the hole is maintained at a predetermined size, and the tongue piece is configured to be reliably bent from the proximal end portion, which is not provided with a peripheral wall, when opening and closing.

(Explanation of Embodiment) To explain an embodiment of the present invention regarding a connector storage cover for connecting electric wires, 1 is a case body having a bulging connector storage recess formed inside, and is made of synthetic resin with appropriate flexibility. The lid body 2 is molded from a material such as synthetic rubber together with the lid body whose surface has approximately the same shape.
is connected to the case body 1 so as to be openable and closable.

Reference numeral 4 denotes claw-like locking pieces that integrally protrude outward at multiple locations on the circumferential surface 1a at the open end of the case body 1.
a and an inclined curved surface 4 toward the tip.
The upper end of the end surface of the locking surface 4a and the circumferential surface 1a of the case body 1 are connected by a bendable elastic piece 4c.

Reference numeral 5 denotes a tongue piece provided at the open end of the lid body 2 so as to face each of the claw-like locking pieces 4 and protrude in a direction parallel to the claw-like locking pieces 4, and a claw-like locking piece is provided at the tip of the tongue piece. A locking hole 6 having substantially the same shape as the locking surface 4a of No. 4 is bored, and furthermore, a locking hole 6 is formed on the outer periphery of the locking hole 6 on the surface side of the tongue piece 5 so as to surround the locking hole 6. A peripheral wall 7 is integrally provided in a protruding manner.

This peripheral wall 7 is formed at the tip of the tongue piece 5 to be equal to or slightly higher than the protruding length between the tip of the claw-like locking piece 4 and the locking surface, and gradually increases in height from the tip toward both side edges. It is formed low, and the base end portion is formed into an elastically bendable flat plate portion 5a without a peripheral wall.

With this structure, after storing the connector (not shown) in the case body 1, the lid body 2 is closed, and the tip of the peripheral wall 7 of the tongue piece 5 is pressed with a finger, and the connector (not shown) is inserted downwardly through the flat plate part 5a. When the tongue piece 5 is bent, the locking hole 6 of the tongue piece 5 is inserted from the tip of the claw-like locking piece 4, and the locking hole 6 of the tongue piece 5 is inserted into the bottom surface of the tip of the inclined curved surface 4b of the claw-like locking piece 4.
When the inner circumferential surface of the distal end is brought into sliding contact with the inner circumferential surface of the distal end thereof, and further insertion is made from this state, the claw-like locking piece 4 curves upward via the elastic piece 4c and opens the locking hole 6 along the inclined curved surface 4b. When the locking hole 6 is completely inserted into the claw-like locking piece 4, the claw-like locking piece 4 closes the elastic piece 4.
It is restored to its original state by the restoring force of c, and the locking hole 6 locks into the locking surface 4a of the claw-shaped locking piece 4.

This operation is sequentially performed on each claw-like locking piece 4 and tongue piece 5 to close the lid body 2 to the case body 1.

In addition, when opening the lid body 2, by hooking your finger on the tip of the tongue piece 5 and pulling it outward, the claw-like locking piece 4 curves upward via the elastic piece 4c and engages the locking hole 6. Locking surface 4
a matches and is easily separated.

In addition, although the connector cover was explained in the above embodiment, the present invention is not limited to this, and it goes without saying that it can be adopted as an opening/closing device for other article storage case bodies.

(Effect of the invention) As described above, according to the storage case body opening/closing device of the present invention, the claw-like locking piece 4 is provided protrudingly from the open end of either the case body 1 or the lid body 2, and A tongue piece 5 having a locking hole 6 that can be engaged with and detached from the claw-like locking piece 4 is provided at the opening end, and the locking hole 6 is provided on the surface side circumference of the tongue piece 5 from the tip to the base end. Since a peripheral wall 7 of an appropriate height is protruded so as to surround the tongue piece 5, when the claw-like locking piece 4 locks the locking hole 6 of the tongue piece 5, the tongue piece 5 is attached to its base. Even when the locking hole 6 is bent, the circumferential wall 7 prevents the locking hole 6 from being curved and deforms, and the locking hole 6 always maintains a predetermined size. In addition, when releasing the lock, the tip of the tongue piece 5 has sufficient elasticity from the peripheral wall 7 and can easily move through the locking hole 6 without bending. It can be removed from the claw-like locking piece 4.
