DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid mounting structure for opening and closing an opening of a molded casing of an apparatus using an FD (floppy disk) or the like.

In this type of device, an opening for inserting and removing the FD, an operation button for a power supply, and the like are provided in the opening of the housing. Open to perform operations. It is desired that the lid can be easily opened and closed.

[0003]

2. Description of the Related Art Conventionally, a claw is provided inside a mold lid,
The claw is hooked on the locking portion on the housing side to lock the lid. When the lid is opened, the nail is bent by pulling the lid, whereby the nail is released from the locking portion and the lid is opened.

[0004]

However, in this conventional method, an extra force is required because the direction in which the claws come off and the direction in which the lid is opened are perpendicular to each other.

It is an object of the present invention to provide a lid mounting structure that can easily open a lid without requiring extra force.

[0006]

According to the present invention , a cover for opening and closing an opening of a housing is provided with a pin provided at a lower portion on one of the housing side and the cover side, and the other side is provided for the pin. In the lid mounting structure for holding openably and closably by engaging with a hole provided, the hole is an elongated hole extending vertically, and is connected to an upper back surface of the lid and a lower surface of an opening of the housing.
While protruding a claw for stopping , the claw, which is inclined downward and protrudes from the upper back surface of the lid , is provided on the housing.
An elastic locking piece provided with an inclined portion for guiding at the tip of the horizontal locking portion is integrally provided, and the position of the elastic locking piece is such that when the lid is closed, the horizontal locking portion is in contact with the lower surface of the claw. engage, and set configured to urge the lid upwardly locking the said pin at one end of the elongated hole.

[0007]

When the lid is closed, the lower surface of the pawl is engaged with the horizontal locking portion of the elastic locking piece, and the lid is urged upward by the locking piece.
As a result, the pin is locked at one end of the elongated hole, and the lid closed state is maintained. When the pin is provided on the housing side, the pin is locked at the lower end of the elongated hole, and when the pin is provided on the lid, the pin is locked at the upper end of the elongated hole.

When the lid is opened, the lid is pushed down. As a result, the locking piece is elastically deformed downward and the pin is locked to the other end of the elongated hole, and at the same time, the pawl slides on the inclined portion of the locking piece and the lid is easily opened.

Thereafter, when closing the lid again, the lid is pushed in. By this operation, the pawl slides on the inclined portion to elastically deform the locking piece downward, and finally the lower surface of the pawl is engaged with the horizontal locking portion and the lid is closed. In this state, the pin is locked at one end of the elongated hole, and the door is kept closed.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing a lid mounting structure of the present embodiment. In the figure, reference numeral 1 denotes a front cover of a molded casing, and 2 denotes a mold lid for opening and closing an opening 1a of the front cover 1. On the back surface of the lid 2, a claw 3 is provided at an upper portion and a rib 4 is provided at a lower portion, and a pin 5 is provided at the rib 4. The claws 3 and the ribs 4 are provided one by one so as to be opposed to the paper surface of the drawing in the vertical direction. Also, front cover 1
A pair of elastic locking pieces 6 engageable with the claws 3 and a pair of elongated holes 7 extending in the vertical direction are formed in the partition wall 1b. ing. The locking piece 6 is a cantilevered shape in which an inclined portion 6b that is inclined downward is integrally provided at the tip of the horizontal locking portion 6a. Although not shown, the partition wall 1b is provided with holes for inserting and removing the FD, operation buttons such as a power supply, and the like.

FIG. 1 shows a state in which the lid 2 is closed, and the lower surface of the claw 3 is engaged with the horizontal locking portion 6 a of the locking piece 6. In this state, the lid 2 is urged upward by the urging force of the locking piece 6, the pin 5 is locked at the upper end of the elongated hole 7, and the lid closed state is maintained. Next, the procedure for opening the lid 2 will be described with reference to FIG.

When the lid is opened, first, as shown in FIG. 2A, the lid 2 is pushed down from the state shown in FIG. 1 to lock the pin 5 at the lower end of the elongated hole 7. In this process, CFC
The pawl 3 locked on the lower surface of the opening 1a of the cover 1
The lower surface of the claw 3 slides down the inclined portion 6b while elastically deforming the locking piece 6 downward . FIG. 2 (B) shows a state where the lid 2 begins to open, the lid 2 from the state shown in FIG. 2 (A)
2B around the pin 5 in the direction of the arrow shown in FIG.
Open. The force to open the lid ( press the lid
Although the illustration is omitted, a concave portion or the like is provided on the outer surface of the lid 2 , for example , in the center of the upper portion , and this is operated by a finger or the like.
Can be given.

Thereafter, when closing the lid 2 again, the lid 2 is pushed in. Due to this operation, the pawl 3 elastically deforms the locking piece 6 downward while sliding on the inclined portion 6b, and finally the lower surface of the pawl 3 is engaged with the horizontal locking portion 6a and the lid 2 is closed. In this state, the pin 5 is locked on the upper end of the elongated hole 7 and the lid closed state is maintained.

In the above description, an example has been described in which a pin is provided on the lid side and an elongated hole is provided on the front cover side.
This may be reversed, in which case the pin locks to the lower end of the slot when the lid is closed. However, it is better to provide a pin on the lid side.
This is advantageous because the lid can be processed (exchanged, etc.) when the pin is broken. In the above description, both the front cover and the lid are made of a mold. However, the present invention can be applied to a case where these are made of an iron plate or the like. However, it goes without saying that the mold is more advantageous in manufacturing (the pin and the elongated hole can be integrally formed).

[0016]

As described above, according to the present invention, the following various excellent effects can be obtained. (1) Since the direction in which the claws come off is the same as the direction in which the lid is opened, the lid can be easily opened only by a downward force applied to the spring portion (elastic locking piece) to remove the claws. (2) In the conventional method, a convex or concave hooking portion is provided on the outer surface of the lid, and a force is applied to the hooking portion to pull the hooking portion. . However, in the method of the present invention, it is only necessary to push down the lid, and the pushing-down force does not need to be so large, so that the recesses and the like for operation can be small, which is advantageous in appearance.
