Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an electrical appliance storage case, and more particularly to an electrical appliance storage case in which a single-opening front plate can be locked with a single touch to the case.

(Prior Art) Conventional casings of this type, particularly those applied to elevator operation panels, are shown in Figs. 6 to 12.
This will be explained based on the diagram. FIGS. 6 and 7 show an example of this, and in the figures, the cover 1 is configured to be closed and engaged with the case 2 by an engagement device to be described later. Cover 1 is on the case side 2a.
A seat 3 is attached along the side surface 2a of the case. The part of the seat 3 that runs along the cover 1 has a female screw 3a.
is formed, and when the cover 1 is closed, the cover 1 is closed off from the case 2 by passing the screw 4 through the hole 1a of the cover 1 and screwing it into the female screw 3a.

FIGS. 8 and 9 show other examples, and the difference between the above example and this example lies in the locking method. According to this example, a pair of stud bolts 5, 5 are attached to the back surface of the cover 1, and a substantially L-shaped leaf spring 6 is fastened to the stud bolt 5 with a nut 7. However, when the cover 1 is closed, the leaf spring 6
is in elastic contact with the case side 2a, and the cover 1 is brought into contact with the case 2.
It is designed to engage with.

Further, FIGS. 10 and 11 show examples other than the above, and according to the figures, there is a
A pair of stud bolts 5, 5 are attached, and a mounting plate 8 having a substantially L-shaped side surface is attached to the stud bolts 5, 5.
is installed. However, in this example, a U-shaped notch 8a is formed in the approximate center of the mounting plate 8 along the case side surface 2a from the tip toward the back surface of the cover 1, and when the cover 1 is closed, the case side surface 2a
It is adapted to receive a protrusion 9 attached to a. Further, a wire spring 10 bent in a dogleg shape is attached to one of the stud bolts 5 together with a mounting plate 8 so as to reciprocate in a notch 8a of the mounting plate 8. Therefore, when closing the cover 1, the notch 8a of the mounting plate 8 allows the protrusion 9 on the case side surface 2a to enter, and when the cover 1 is pushed further, the protrusion 9 resists the elasticity of the wire spring 10. When the cover 1 is entered and closed, the protrusion 9 reaches a position surrounded by the wire spring 10 and the notch 8a, thereby locking the cover 1 to the case 2.

[Problem that the invention attempts to solve]

However, in the first example, the cover 1 had to be attached to or removed from the case 2 using a tool such as a screwdriver, and since the screws 4 were exposed on the surface of the cover 1, the appearance was not good.

In addition, in the second and third examples, although the cover 1 has no screw holes on the surface and looks good, the cover 1 is only fixed to the case 2 by the plate spring 6 and the wire spring 10. First, the cover 1 can be opened freely, which causes various problems.

The present invention has been made to solve the above-mentioned problems, and aims to provide an electrical appliance storage case that allows the cover to be locked to the case with a single touch and has a good appearance.

[Means for solving problems]

The electrical appliance storage casing according to the present invention includes an engagement device that closes and engages a top plate with respect to a case for storing an electrical appliance, and the engagement device includes a rear surface of the top plate along a side surface of the case. A protrusion protruding from the protrusion, a plate spring member attached to either the protrusion and the side surface of the case substantially parallel to the protrusion, and a plate spring member attached to either the case side or the plate spring member on the other side. a hole formed in either the plate spring member or the protrusion piece so that the protrusion fits into the protrusion and locks the plate; It includes a gap formed in the plate, and an unlocking piece that is inserted into the gap and presses the pressing part of the plate spring member to elastically deform the plate spring member so that the protrusion comes out of the hole and unlocks the lock. It is something.

[Effect]

According to the present invention, the top plate can be engaged and locked with the case with a single touch, and the top plate can be removed by unlocking the engaging device by simply inserting an unlocking piece between the two.

〔Example〕

Hereinafter, the present invention will be explained based on the embodiment shown in FIGS. 1 to 5, with the same reference numerals assigned to parts that are the same as or corresponding to the conventional ones. In each figure, FIGS. 1 to 3 show the first embodiment. According to the figures, a projection piece 11 along the case side surface 2a is attached to the back surface of the cover 1 at a distance from the case side surface 2a. Furthermore, a hinge 12 is attached to the protruding piece 11. The support shaft of the hinge 12 is located on the tip end side of the protrusion, and a wire spring 13 is attached to the support shaft so that the hinge 12 can expand and contract elastically. Hinge 12
As is clear from FIGS. 2 and 3, at the center of the open end on the opposite side of the
is formed, and the protrusion 12a enters into a groove 1b as a gap formed at the edge of the cover 1.

Then insert the unlocking piece (not shown) into the groove 1b of the hinge 1.
When the cover 1 is inserted against the elasticity of the cover 1 as described below,
The case 2 can be opened from the case 2. That is, a pair of holes 12b, 12b are formed on both side edges of the hinge 12 on the side of the case side 2a, and a pair of holes 12b, 12b are provided with claws 15, which are attached to the case side 2a via mounting plates 14, 14, respectively. 1
5 is configured to fit therein. The claw 15 has a right triangular side surface as shown in FIG.
It is attached to 4.

Therefore, when cover 1 is pushed into case 2, claw 1
5 and 15 resist the elasticity of hinge 12 while hinge 1
2 and fit into the holes 12b, 12b to lock the cover 1 to the case 2. In other words,
In this state, even if you lose the unlocking piece and try to remove the cover 1, the sides of the claws 15, 15 vertically rising from the mounting plates 14, 14 intersect with the holes 12b, 12b, making it impossible to remove it. . To remove the lock, push the unlocking piece into the groove 1b of the cover 1, elastically deform the hinge 12, and insert the claws 15 into the hole 12.
It must be done after it is engaged and disengaged from b and 12b.

FIGS. 4 and 5 show another embodiment of the present invention, in which the cover 1 is constructed so as to be attached to the panel 16 on the same plane via a narrow diameter δ. On the back surface of the cover 1, a protrusion piece 11 is screwed onto a stud bolt 5 with a nut 7, as in the above embodiment. On the other hand, there is a hinge 1 on the bottom of case 2.
2 is attached to one side of the hinge 12, and a leaf spring 17 extending between the protrusion piece 11 and the case side surface 2a is attached to one side of the hinge 12.
is installed. Further, the tip of the leaf spring 17 is bent into a substantially dogleg shape so as to face the protruding piece 11, and the cover 1 is further formed with a narrow .delta. so as to face the inclined surface of the tip. Therefore, when an unlocking piece (not shown) is inserted through the narrow δ, the leaf spring 17 is elastically inclined toward the side surface 2a of the case. In addition, a claw 15 is provided on the protruding piece 11 side of the leaf spring 17 via the mounting plate 14 as in the above embodiment.
is attached, and the protruding piece 11 has a hole 11a into which the claw 15 fits when the case 2 is closed with the cover 1.
is formed. Therefore, when the cover 1 is pressed against the case 2, the tip of the protruding piece 11 comes into contact with the inclined surface of the claw 15, and when the cover 1 is pushed further, the leaf spring 17 is elastically tilted toward the side surface 2a of the case, and finally the claw 15
will fit into the hole 11a of the protrusion piece 11.
Therefore, in this embodiment as well, the case 2 can be closed and locked with the cover 1 with a single touch, as in the first embodiment, and cannot be unlocked in that state. It can be easily unlocked using a lock piece.
