Description

[Detailed explanation of the idea] The present invention relates to a device for fixing a front panel at the front.

For example, when the main parts of a wall-mounted air conditioner consist of a main body and a front panel, the front panel must generally be fixed to the main body by some method.

In appearance, it is generally fixed on the side.

FIG. 1 schematically shows this, where 1 is a main body equipped with a heat exchanger, blower, etc., 2 is a front panel having an outlet grille 3, and is fixed on both sides with fixing devices 4, respectively.

5 is a suction grill, which is fixed to the vehicle body 1 after the front panel 2 is attached.

6 is a suction port.

A conventional example of this front panel fixing device 6 is shown in FIG.

7 is a lock plate connected to the front panel 2;
A U-shaped groove 7a is provided that protrudes parallel to the side surface 1a of the main body 1.

8 is a fixing screw that tightens the U-shaped groove 7a of the lock plate, 8a is a knurled groove provided on the outer periphery of the fixing screw 8,
8b is a slot provided in the head of the fixing screw 8.

In such a configuration, in order to fix the front panel 2, after hooking the upper part of the front panel 2 to the main body, insert the U-shaped groove 7a of the lock plate 7 between the side plate 1a of the main body 1 and the fixing screw 8, Tighten the fixing screw 8 with your fingers using the knurled groove 8a, and then tighten the slotted groove 8a of the fixing screw 8.
Insert a screwdriver, hard tool, etc. into the lock plate 7 and tighten it to the extent that the lock plate 7 does not move in the 1-open direction as shown in FIG.

In addition, when releasing the front panel 2, perform the operation opposite to the above-mentioned fixing operation.

In this case, in order to fix the front panel 2 to the main body 1, it is necessary to push the front panel 2 in the 1-closed direction in Fig. 2 and tighten the fixing screws 8.
The relative position of the front panel 2 and the front panel 2 cannot be determined accurately.

Further, in order to tighten the fixing screw 8, it is necessary to turn it one or two revolutions, which is not easy to operate, and furthermore, a screwdriver or a hard tool is required for final tightening.

This is a similar phenomenon when releasing the front panel 2, except that the operation is reversed.

Furthermore, the final tightening mentioned above depends on the force being applied,
In this case, the holding force of the lock plate 5 tightened between the main body 1 and the fixing screw 7 may not be stable, and the front panel 2 may move in the 1-open direction shown in FIG.

This invention is intended to improve the above-mentioned drawbacks, and includes a fixing device made of synthetic resin that has the three functions of guiding, locking, and unlocking the lock plate. This combination allows the front panel to be fixed (released) to the main body easily and reliably.

The present invention will be explained with reference to an embodiment shown in FIGS. 3 to 6.

In FIG. 3, 10 is a square hole provided in the lock plate 5 connected to the front panel 2, and 11 is a fixture made of synthetic resin that is press-fitted into the square hole 12 provided in the side plate 1a.
Fixed.

The fixing device 11 is like a normal bushing in FIG.
It is fixed in the square hole 12 by being press-fitted from the upper surface of the side plate 1a by the flange 13, the groove 14, and the claw 15 that is press-fitted into the square hole.

These form the fixed part of the fixture.

Reference numeral 16 denotes a projection that engages with the square hole 10 of the lock plate 5, and is connected to the flange 13 only at that end so as to bend at the end on the lock plate 5 side.

17 is a hinge portion.

18 is a protrusion for unlocking. Reference numeral 19 denotes a guide plate of the lock plate 5, which is connected to the flange 12 on the opposite side to the hinge.

In this configuration, when fixing the front panel 2 to the main body 1, when the front panel 2 is pushed in the direction of 1 close as shown in FIG. 3, the lock plate 5 connected to the front panel is It is guided by the guide plate 19 and guided between the plate guide 19 and the locking protrusion 16.

At this time, the tip of the lock plate 5 hits the inclined part 16a of the locking protrusion 16 shown in FIG. do.

Subsequently, the lock plate 5 locks the lock protrusion 16.
is pressed and when the square hole 10 reaches the position of the locking protrusion 12, the elasticity of the hinge 17 causes the locking protrusion 12 to enter the square hole 10 as shown in FIG.
The vertical portion 16b of 6 hits one side of the square hole 10 and is completely locked.

When removing the front panel 2 from the main body 1, press the lock release protrusion 18 with your finger in the direction of the arrow shown in FIG.
Deforms inward from the hinge 17 and locking protrusion 16
is pulled out from the square hole 10 and the lock is released.

Next, in this state, the front panel 2 can be removed by pulling it in the 1-open direction shown in FIG.

The position of the front panel 2 in the front direction is determined by the vertical part of the locking protrusion 16 hitting the square hole, and the position in the depth direction is determined by, for example, the front panel 2 hitting the front piece 1b of the side plate 1a in FIG. It is something.

As described above, according to the front panel fixing device according to the present invention, the lock plate 5 is simply connected to the front panel 2.
simply by pushing it into the fixture 11 attached to the main body 1, it will be automatically locked and positioned, and the front panel 2
When removing the lock from the main body 1, the lock is released by simply pressing the finger rest such as the lock release projection 18, and the lock can be easily fixed and released.
