The present invention relates to a structure for attaching a cover member to a device.

2. Description of the Related Art As a structure for attaching a cover member to the chassis of an electronic device by mechanical engagement, for example, a part of the side plate of the cover member is provided with an inward L-shaped bending piece, and this is inserted into the recess of the chassis. There is a structure in which they fit together.

Problems to be Solved by the Invention When a force is applied to the attached cover to press it or to remove the cover from the chassis, the L self-shaped bending piece receives a force in the direction of bending and becomes relatively It bends easily. When the L-shaped bent piece bends, it becomes easier to slip out of the recess of the chassis. In some cases, the L-shaped bent piece can slip out of the recessed part, causing the cover member to come off from the chassis, resulting in problems in terms of reliability. It was hot.

Means for Solving the Problems In the present invention, the front end of the cover member is engaged with the decorative frame, and the rear end of the cover member is inserted into the chassis on one of its left and right sides, and the other side is inserted into the chassis. The configuration is screwed.

As for the part to be sandwiched between the chassis, the sandwiching part is provided in the cover member, and a pair of tongues, at least one of which is inclined inward, is provided, and between the pair of tongues, the sandwiched part of the chassis is formed. It has a structure in which it is sandwiched between the two.

Function: The structure in which the front end sides of the cover members are engaged, one of the left and right sides of the rear end is sandwiched, and the other is screwed down works so that screwing can be done in one place.

The slanted tongue piece of the sandwiching part of the cover member can be used when the attached member is pushed, for example.
The force acting on the inclined tongue is in the direction of its surface, and acts so that the tongue does not bend easily. Furthermore, even if it bends, the direction in which the tongue piece bends is not in the direction in which it comes off from the clamping part, but in the direction in which it bites into the clamping part, so that the cover member acts to prevent it from coming off.

Embodiment FIG. 1 shows a part of an embodiment of the cover member mounting structure for, for example, a floppy disk device according to the present invention, and FIG. 2 shows the entire structure.

1 is a cover member, and 2 is a chassis.

The cover member 1 is comprised of a top plate part 20 and side plate parts 3 (one not shown) that hang down on both the left and right sides of the top plate part 20, and has a substantially inverted U-shape.

A head carriage and the like are provided on the chassis 2, and a decorative frame 21 is erected on the front end side of the chassis 2. An engagement groove 2 is provided on the back side of this decorative frame 21.
2 is formed.

As shown in FIGS. 3 and 4, a sandwiching portion 4 is provided on the side plate portion 3 of the cover member 1. As shown in FIGS. The sandwiching portion 4 includes a pair of tongue pieces 5 and 6 formed by cutting and raising a portion of the side plate portion 3 inward. The tongue pieces 5 and 6 are lined up in the height direction of the cover member 1. Further, the tongues 5 and 6 are inclined inward of the cover member 1 in a state similar to a double door, and their tips 5a and 6a are opposite to each other.

On the side vertical wall 7 of the chassis 2, a clamped portion 8 is provided.
is provided. This pinched portion 8 is formed relatively to the recessed portion 9 on the outer surface of the vertical wall 7, and is formed within this thickness without protruding outward from the vertical wall 7.

The distance A between the tips 5a and 6a of the tongue pieces 5 and 6 is
It is determined to be approximately equal to the height dimension B of the held portion 8.

This cover member 1 is held in an oblique position with the rear end side slightly raised above the front end side, and the front end side is engaged with the engagement groove 22 of the decorative frame 21, and then the rear end side is moved to the arrow mark E in FIG. Push down as shown in to make the pinching part 4 sandwich the pinched part 8, and finally, tighten the screw 2.
By screwing 3, it can be attached to the chassis 2 with good workability.

The cover member 1 has a decorative frame 2 on the tip side.
1, and on the rear end side,
Of the left and right sides, as shown in FIG. It is screwed and attached to the chassis 2.

Looking at the pinching part 4 and the pinched part 8,
The cover member 1 has its displacement in the direction of arrow C limited by the tongue piece 5 and the clamped part 8, and its displacement in the direction of arrow D by the tongue piece 6 and the clamped part 8, and is restricted in the direction of arrows C and D. It is installed with its displacement regulated.

When a force in the direction of arrow C or a force in the direction of arrow D is applied to the cover member 1, the tongue pieces 5,
The forces acting on the tongues 6 act in the plane direction of the tongues 5 and 6, as shown by arrows C ₁ and D ₁ , respectively. Therefore, the tongue pieces 5 and 6 are not easily bent. Therefore, the cover member 1 is firmly attached to the chassis 2.

Further, even if the force acting on the cover member 1 is large and the tongue pieces 5 and 6 are bent, there is no problem because the direction of the bending is not in a direction in which they are removed from the clamped part 8, but in a direction in which they bite into the clamped part 8. .

In addition, in the process of pushing down the cover member 1 in the direction of arrow E in FIG. It crosses over and fits into the recess 9. That is, the engagement of the pinching part 4 with the pinched part 8 is performed in the process of pushing down the cover member 1, and no special operation is required to engage the pinching part 4 with the pinched part 8. This also improves the workability of attaching the cover member 1, in combination with the fact that only one screw is required.

When repairing an electronic device, the gripping portion 4 is disengaged from the gripped portion 8 and the cover member 1 is removed.

The engagement of the pinching part 4 (tongue piece 6) with the pinched part 11 can be easily released by expanding the rear end side of the side plate part 3 outward as shown by arrow F in FIG. That is, when the rear end side of the side plate part 3 is expanded outward, as shown in FIG. 5, the tongue piece 6 slips out from the recess 9 and comes off from the clamped part 8, and the cover member 1 becomes movable upward. .

Further, due to the presence of the opening window 10 formed in the side plate part 3, the side plate part 3 is easily flexible, and the operation of expanding the side plate part 3 outward as described above can be performed with a small force, making the operation easy.

FIGS. 6 and 7 show another embodiment of the sandwiching part, and the difference from the above embodiment is that the upper tongue piece 5 of the pair of inclined tongue pieces 5, 6 (see FIG. 3) is made into a vertical tongue piece 11. The vertical tongue piece 11 and the inclined tongue piece 6 form a sandwiching part 12.
Configure.

Since the position of the lower edge 11a of the tongue piece 11 is determined with good precision, the tip 6a of the tongue piece 6 and the lower edge 1 of the tongue piece 11 are
1a has better accuracy than the above configuration. Furthermore, the tongue piece 11 is easier to form than an inclined tongue piece.

The pinching portion 12 is in a state in which the pinched portion 8 is sandwiched between the lower edge 11a of the tongue 11 and the tip 6a of the tongue 6, as shown in FIG.

The force when the cover member 1 is pressed in the direction of arrow C acts on the tongue piece 11. At this time, tongue piece 1
The force acting on the tongue piece 11 is in the direction of its surface as shown by the arrow _C2 , and the tongue piece 11 does not bend easily. A description of the tongue piece 6 will be omitted, but it functions in the same manner as described above. As a result, the cover member 1 is firmly attached to the chassis 2 in the same manner as described above.

Further, the present invention can be applied to other electronic devices such as magneto-optical disk devices, optical disk devices, cassette decks, and radios (car stereos).

Effects of the Invention As described above, according to the cover member mounting structure for electronic equipment of the present invention, only one screw is required, and the cover member can be attached with better workability than a structure in which screws are fastened at multiple locations. I can do it.

Moreover, looking at the structure of the pinching part and the pinched part, when an external force acts on the attached member, a force in the plane direction acts on the inclined tongue piece, making it difficult for the tongue piece to bend. Moreover, even if the tongue piece is bent, this direction is the direction in which it will bite into the part to be held, so there is no risk of the tongue piece coming off from the part to be held, improving the reliability of the installation. It has the advantage of obtaining
