The inclination angle is determined so that the vehicle can be overcome.

Reference numeral 30 is a leaf spring made of metal or non-metal such as plastic and having a substantially U-shaped cross section.
0 and the support wall 20 are mounted from the distal end side so as to sandwich the connection wall 10 and the support wall 20, and the outer surface of the connection wall 10 and the inner surface of the support wall 20 are elastically attached in a direction in which they approach each other. I am energetic. The leaf spring 30 is prevented from being displaced with respect to the support wall 20 by fitting and fixing a fixing claw 31 formed on the tip end portion of the support wall 20 side into a fixing hole 23 formed in the support wall 20. And is always held in place.

Since the leaf spring 30 urges the outer side surface of the connecting wall 10 and the inner side surface of the support wall 20 to approach each other, they project at the same height as shown in FIG. The tips of the moving projection 12 and the fixed projection 22 are elastically pressed and abutted against the outer surface of the support wall 20 and the outer surface of the connecting wall 10, respectively.

Next, the operation of the grill mounting mechanism of the air conditioner of the present embodiment constructed as described above will be described.

The grill 2 in the closed state shown in FIG. 3 is pulled toward the front side to open the grill 2, and the connecting wall 10 is moved to the rotating shaft 1.
When the grill 2 is rotated in the opening direction around the center, the contact surface 12a of the moving projection 12 is moved by the elastic force of the leaf spring 30 on the front side where the grill 2 is opened to a predetermined angle. It elastically contacts the contact surface 22a of the portion 22. When the connecting wall 10 is further rotated slightly in the opening direction, the contact surface 12a of the moving projection 12 resists the elastic force of the leaf spring 30 and the leaf spring 3
0 is deformed and slides on the contact surface 22a of the fixed projection 22 to get over. When the connecting wall 10 is further rotated in the opening direction, the leaf spring 30 returns to its original shape as shown in FIG. 4, and the engaging surface 12b of the moving projection 12 is elastically moved by the leaf spring 30. The grill 2 is held in an open state at a predetermined angle by elastically abuttingly locking the locking surface 22b of the fixed protrusion 22. When the grill 2 is open, the leaf spring 3
0 urges the connecting wall 10 and the supporting wall 20 toward each other, so that the locking surface 12b of the moving projection 12 is stably locked to the locking surface 22b of the fixed projection 22 and the grill 2 The moving protrusion 12 does not separate from the fixed protrusion 22 and the grill 2 is not closed abruptly during the replacement of the filter with the filter.

When the grill 2 is closed from the open state, the grill 2 is pressed toward the panel 1 and the connecting wall 10 is rotated in the closing direction.
However, the leaf spring 30 is deformed against the elastic force of the leaf spring 30,
By sliding over the locking surface 22b of the fixed protrusion 22 to get over and further rotating the connecting wall 10 in the closing direction, the grill 2
Is attached to the panel 1. It should be noted that, with the grill 2 mounted on the panel 1 and the panel 1 completely covered, the tips of the moving projection 12 and the fixed projection 22 are moved to the inside of the support wall 20 by the elastic force of the leaf spring 30. Since the side surface and the outer side surface of the connecting wall 10 are pressed and come into contact with each other to exert a supporting force, the grill 2 does not open suddenly when the air conditioner is used.

During the opening / closing operation of the grill 2 described above,
Due to the elastic force of the leaf spring 30, the connecting wall of the grill 2 is connected.
10 and the supporting wall 20 of the panel 1 are urged to move the moving projection 12
And the fixed protrusions 22 are always elastically abutted against each other.
It Therefore, the grill 2, the connecting wall 10, or the panel 1
And some dimensional errors and variations in the support wall 20 are absorbed.
At the same time, the opening / closing force of the grill 2 becomes constant. Also,
When the moving protrusion 12 gets over the fixed protrusion 22, a predetermined resistance is applied.
It gives a feeling and serves as a guide when opening and closing the grill 2. Change
In the leaf spring 30, the fixing claw 31 is attached to the panel 1 side,
That is, it is fitted and fixed in the fixing hole 23 of the support wall 20 provided on the fixed side.
Since the connection wall 10 is rotated,
It will not be done.

As described above, in the grill mounting mechanism of the air conditioner of the above-described embodiment, the fixing projection 22 is provided as a panel side locking portion at a predetermined position on the inner side surface of the support wall 20 of the panel 1, and the panel 1 is provided on the panel 1. A movable projection 12 provided on the outer surface of the connecting wall 10 of the grill 2 which can be rotated and opened / closed as a locking portion on the grill side.
Can be engaged with the fixed projection 22 in a concave-convex relationship with the grill 2 opened to the panel 1 by a predetermined angle, and the leaf spring 30 as the urging means serves to secure the support wall 20 of the panel 1. The inner side surface and the outer side surface of the connecting wall 10 of the grill 2 are urged toward each other.

Therefore, in the above embodiment, when the grill 1 is pulled toward the front to open it, the elastic force of the leaf spring 30 causes the fixed projection 22 of the support wall 20 to the outer surface of the connection wall 10 and the connection. When the moving projections 12 of the wall 10 move on the inner surfaces of the support wall 20 elastically in contact with them and open the grill 2 by a predetermined angle, the moving projections 12
Is elastically locked to the fixed protrusion 22, and the grill 2 is held in an open state with a predetermined angle. As a result, some dimensional errors and variations are absorbed, the opening / closing force of the grill 2 is constant, the opening / closing operation can be performed easily and smoothly, and stable quality can be secured in the opening / closing operation of the grill 2.

By the way, the moving projection 12 and the support projection 22 of the above-mentioned embodiment are formed so as to project from the connecting wall 10 and the support wall 20 at the same height. It is not limited, and it may be any as long as it engages with each other due to the concavo-convex relationship and functions as a locking portion that can hold the grill 2 with respect to the panel 1 in a state of being opened at a predetermined angle. For example, the projecting heights of the moving projection 12 and the fixed projection 22 may be different, and the panel 1
It is also possible to adopt a structure in which one of the locking portion on the side and the locking portion on the side of the grill 2 is a protrusion and the other is a recess so that the protrusion is locked in the recess when the grill 2 is opened at a predetermined angle. is there. Further, the moving projection 12 and the fixed projection 22 are respectively provided with contact surfaces 12a and 22a and locking surfaces 12b and 22.
However, the movable protrusion 12 and the fixed protrusion 2 are included.
It is also possible to make 2 a substantially hemispherical projection, or to make one of them a substantially hemispherical projection and the other a substantially hemispherical recess capable of locking the projection. However, changing the protruding height
Example was the when implemented as moving the projection 12 and the fixing protrusion portions 22, since the connecting wall 10 and the support wall 20 is supported at one point of the mobile projection 12 and the fixing protrusion portions 22, to the support wall 20 The friction of the rotation of the connecting wall 10 is reduced, and the opening / closing operation of the grill 2 is further facilitated.

Further, the leaf spring 30 of the above-mentioned embodiment is the connecting wall 1
0 and the supporting wall 20 are sandwiched, but the present invention is not limited to this, and the outer surface of the connecting wall 10 and the inner surface of the supporting wall 20 are close to each other. And functions as a biasing means for stably and elastically abutting the moving projection 12 and the fixed projection 22 on the inner side surface of the support wall 20 and the outer side surface of the connecting wall 10. I wish I had it. However, when the biasing means is implemented as the leaf spring 30 as in the above embodiment, the biasing means is less likely to be damaged, and the structure of the biasing means is simplified. .

The urging means can be configured as shown in FIGS. 5 and 6, for example. FIG. 5 is an enlarged cross-sectional view of an essential part of a grill mounting mechanism for an air conditioner according to a second embodiment of the present invention, and FIG. 6 is an enlarged longitudinal cross-sectional view of an essential part of a grill attachment mechanism for an air conditioner according to a third embodiment of the present invention. It is a figure.

In the figure, the rotary shaft 11 has an end protruding from the shaft hole 21 of the support wall 20, and a housing groove 11a is formed over the entire circumference of the protruding end. A C-shaped ring 41 is fitted and housed in the housing groove 11a, the inner surface of which elastically abuts the outer surface of the support wall 20, and the connecting wall 10 and the support wall 2
0 and 0 are urged toward each other.

In the case of the second embodiment of the present invention, since the urging means is composed of the C-shaped ring 41 fitted in the accommodation groove 11a of the rotary shaft 11, the urging means is downsized and the air pressure is reduced. The grill attachment mechanism of the harmony machine can be made more compact.

Further, in the third embodiment of the present invention, instead of providing the accommodating groove 11a in the rotary shaft 11 and fitting the C-shaped ring 41 therein, a stopper means such as a flange is provided at the tip of the rotary shaft to provide a stopper. A biasing means having an elastic force in the axial direction, such as a disc spring or a coil spring, is interposed between the means and the outer surface of the support wall 20 so that the connecting wall 10 and the support wall 20 approach each other. It is also possible to adopt a configuration in which
