Abstract

PURPOSE:To draw out an air-conditioning case body with both hands easily and without impairing it by contriving a fitting device in such a way that a lock-releasing slide plate is pressed by inserting a screwdriver or the like into the gap between louver boards and by depressing an elastic locking part for unlocking it, so that even if the screwdriver is unhanded, the unlocked condition can be maintained as it is. CONSTITUTION:A U-shaped slit 2 is formed on at least one surface out of the upper and lower surfaces of an air-conditioning case body 1, and making a boundary of this U-shaped slit 2, a pair of elastic locking parts 3 capable of being vertically moved are formed in the side thereof, and both are integrally connected to a connecting plate. The air-conditioning case body 1 fitting device is constituted in such a way that the elastic locking parts 3 are detachably locked to the rear part of the opening edge 5 of an instrument panel, and a lock-releasing slide plate 6 for displacing the connecting plate downwards is fitted on the upper surface of the air-conditioning case body 1 situated opposite to the connecting plate so as to be slidable in the front-and-rear direction, and on the undersurface thereof an operational projection 7 is provided so as to be projected toward the inside of the air-conditioning case body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device in which an air conditioning case body is detachably attached to an instrument opening edge.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, one end of a mounting spring bent into a mountain shape is fixed to the upper and lower surfaces of an air-conditioning case body, the tip is projected inward, and the mounting spring is locked to the rear portion of the instrument opening edge. However, an attachment device for an air conditioning case body is known in which a driver or the like is inserted through the louver gap on the front surface of the air conditioning case body to remove it, the tip of the attachment spring is pushed downward, and in this state, the tip is pulled out from the instrument opening edge.

[0003]

In the above prior art, when the air conditioning case body is removed, the locking spring that is locked at the rear portion of the instrument opening edge is moved downward by the tip of the driver inserted through the louver gap. There is a problem that it is difficult to work because both hands cannot be used because it is pressed to release the lock and pulled out, and it is easily scratched. The present invention aims to solve the above problems.

[0004]

In order to achieve the above object, the present invention forms a U-shaped slit on at least one upper and lower surface of an air-conditioning case body, and a pair of U-shaped slits are formed inside the air-conditioning case. Forming an elastic locking part that moves up and down, integrally connecting both by a connecting plate, and the elastic locking part is detachably locked to the rear part of the instrument opening edge, and the connecting plate is displaced downward. The lock releasing slide plate is slidably attached to the front and rear directions of the upper surface of the air conditioning case body facing the connecting plate, and the operating protrusion is provided on the lower surface of the sliding plate for projection inside the air conditioning case body.

[0005]

Operation: The tip of a driver or the like presses the lock releasing slide plate to displace the elastic locking portion locked at the rear portion of the instrument opening edge downward, remove it, and pull out from the instrument.

[0006]

[Example] On at least one of the upper and lower surfaces of the air conditioning case body 1,
A U-shaped slit 2 is formed, and a pair of elastic locking portions 3 are formed on both sides inside the U-shaped slit 2 as a boundary, and both opposing side portions are integrally connected by a connecting plate 4, and this connection is performed. A tapered surface 4a is formed on the upper surface of the plate 4 so that the elastic locking portion 3 is locked to the rear portion 5a of the instrument opening edge 5. Reference numeral 6 denotes a lock releasing slide plate that presses the taper surface 4a of the connecting plate 4, and an operating protrusion 7 that protrudes inside the air conditioning case body 1 is projectingly provided on the lower surface thereof.
It is fitted in the groove 8 by a locking claw so as not to come out, and can slide back and forth.

Next, the operation will be described. When the air conditioning case body 1 is incorporated into the instrument opening edge 5, the lock release slide plate 6 is pushed from the front side of the instrument opening edge 5 while being separated from the taper surface 4a of the connecting plate 4, and elastically locked to the rear portion 5a of the instrument opening edge. Lock the part 3. When removing the air conditioning case body 1 from the instrument opening edge 5, insert a screwdriver or the like into the louver gap on the front surface of the air conditioning case body 1 and push the operating protrusion 7 at its tip to push the tapered surface 4a of the connecting plate 4 inward. The elastic locking portion 3 is removed from the rear portion 5a of the instrument opening edge 5. Since this state is maintained even when the driver releases his / her hand, the air conditioning case body 1 is pulled out from the instrument opening edge 5 with both hands.

[0008]

According to the present invention, a U-shaped slit is formed on at least one of the upper and lower sides of the air conditioning case body, and a pair of vertically movable elastic locking portions are formed inside the U-shaped slit as a boundary. Then, the both are integrally connected by a connecting plate so that the elastic locking portion is detachably locked to the rear part of the instrument opening edge, and the lock releasing slide plate for displacing the connecting plate downward is opposed to the connecting plate. The air-conditioning case body is slidably mounted in the front-back direction, and the lower surface of the air-conditioning case body is provided with an operating protrusion so that a screwdriver or the like can be inserted through the louver gap on the front of the air-conditioning case body to unlock the slide. The plate can be pressed to release the elastic locking portion, and the state can be maintained even if the hand is released, so both hands can be used, and it can be easily removed without damaging it.
