Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION Field of the Invention The present invention is usually covered, and the cover is detached when necessary, and is used in a place where various functions and the like in the cover are used. Device.

2. Description of the Related Art A conventional detachable cover device of this type has a structure as shown in FIG. 5, such as a battery case cover of a remote control box.

That is, the battery case cover 2 is fixed to the remote control box 1 by the fitting claws 2e and 2f.

However, with such a structure, the fitting claw 2e
In order to realize such a shape, the battery case cover 2 must be a molded part by a mold, and the remote control box 1 for mounting the battery case cover 2 is also a complex mold using side cores in the mold. There is a problem that an extremely expensive investment is required even if a shape is required and a mold investment amount is taken as an example.

Therefore, the present invention can realize a detachable cover device at a very low price without impairing easy detachability, by making the battery case cover a very simple flat plate shape.

Means for Solving the Problems The technical means of the present invention for solving the above problems includes a cover that can be attached to the opening of the cabinet, and upper and lower ends of the cover provided at the upper and lower ends of the opening. First and second notches into which a portion can be inserted, and cover holding ribs provided on the left and right of the opening and having a tapered portion,
The second notch is such that, when the cover is pressed into the innermost position of the tapered portion and is bent along the cover holding rib, the tip of the lower end of the cover is located outside the second notch. The cover is provided such that the tip of the lower end of the cover is located inside the second cutout when the cover is pressed upward with the cover attached to the opening.

Operation The operation of this technical means is as follows.

That is, when the cover is attached to the cabinet, one end of the cover is inserted along the taper of the rib for holding the cover of the cabinet, and the other end of the cover is bent at the two cutouts of the opening of the cabinet while bending the cover. Fit the claws on both ends and attach.

When removing the cover, the tabs at both ends of the cover are fitted with the tabs of the cover of the cabinet by pressing one end of the cover, which has the tapered portion of the cover holding rib in the opening of the cabinet. The cover is removed from the cabinet by removing the cover from the notch.

As a result, the cover can be easily attached to and detached from the cabinet with a cover having a simple shape having only claws on either the left or right or upper and lower ends of the flat plate.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 to 3 show cross-sectional views when the cover is inserted into the cabinet.

 FIG. 4 is a perspective view of a cabinet and a cover.

In FIG. 1, when the flat-plate-shaped flexible cover 1 is attached to the opening of the cabinet 2, first, the claws 1 a at the upper end of the cover 1 are provided on the left and right sides of the opening of the cabinet 2. Along the tapered rib 2a having a tapered portion whose side is inclined toward the depth direction, it is pushed in the direction of the arrow to the depth of the tapered portion.

Next, as shown in FIG. 2, the upper end of the cover 1 is bent along the tapered rib 2a while being pushed into the innermost position of the tapered portion, and the claw 1b at the lower end of the cover 1 is cut out of the cabinet 2. Insert into 2d.

As a result, as shown in FIG. 3, the claws 1a and 1b at the upper and lower ends of the cover 1 fit into the notches 2c provided at the upper end of the opening of the cabinet 2 and 2d provided at the lower end. The cover 1 is attached to the cabinet 2 by the horizontal portion of the tapered rib 2a, which is held from the back side of the opening.

As described above, when the cover 1 is attached, as shown in FIG. 2, the entire length of the cover 1 is shortened because the cover 1 is bent. As a result, since the tip of the claw 1b at the lower end of the cover 1 is located outside the notch 2d, the claw 1b can be inserted into the notch 2d.

However, after the cover 1 is attached, the entire length returns to the original length since the bending is eliminated as shown in FIG.
As a result, even if the cover 1 is slid in the vertical direction, the tips of the claws 1a and 1b of the cover 1 are located inside the cutouts 2c and 2d, and therefore do not come off naturally.

Conversely, when removing the cover 1 from the cabinet 2, by pushing the cover 1 in the direction of the arrow shown in FIG. 3, the claws 1 a and 1 b at both ends of the cover 1 are removed from the notches 2 c and 2 d of the cabinet 2. Remove cover 1 from cabinet 2.

Advantageous Effects of the Invention The present invention includes notches provided at the upper end and lower end of an opening of a cabinet, and cover holding ribs having tapered portions provided on the left and right of the opening, and the cover is pushed into the tapered portion. When bent in the state, the tip of the lower end of the cover is located outside the notch, and when pressed upward with the cover attached to the opening, the tip of the lower end of the cover is By providing the cover inside, the cover does not come off naturally, and the cover can be easily attached to and detached from the cabinet.

Further, the cover has a simple flat plate shape, and can be manufactured easily and at low cost without using a mold having a complicated shape.
