Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a defroster duct, and more particularly, to a mounting structure for mounting a defroster duct in which a nozzle and a hose are integrally molded to an instrument panel.

Generally, cars have a defroster system that connects an air conditioner and an air outlet formed in the instrument panel with a defroster duct to prevent the windshield and side windows from fogging up due to the warm air sent out from the air conditioner. is provided.

By the way, conventionally, as a structure for connecting the nozzle of the defroster duct to the air outlet of the instrument panel, a flange with an engagement groove is provided on the outer periphery of the nozzle, as seen in, for example, Japanese Utility Model Publication No. 48-2829. The connection can be made by fitting the engagement groove of this flange to the edge of the air outlet, or by providing a wide flange around the outer periphery of the tip of the nozzle and directly fixing this flange to the panel with screws. However, with the former structure, there is a risk that the nozzle may separate from the air outlet or the installation position may shift due to the tensile action caused by the piping of the defroster duct; Particularly in places where the working space is narrow, it is difficult to accurately place the nozzle on the outlet and screw the screw onto the flange, and therefore it takes time and effort to connect the nozzle to the outlet.
Furthermore, when the defroster nozzle is formed by blow molding, it is difficult to form a wide flange on the outer periphery of the nozzle, and it is not possible to adopt a structure in which the flange is directly screwed to the panel as described above. There isn't.

The present invention was devised in view of these circumstances, and the purpose is to create a defroster nozzle that has an extremely simple configuration, allows the nozzle to be easily connected to the instrument panel, and does not shift its mounting position. We are trying to provide a mounting structure for this.

More specifically, a flange is provided at the tip of the nozzle, and a protrusion that protrudes toward the hose is provided, and a presser plate is formed that has an engagement hole that engages with the protrusion, and the presser plate holds the flange. By pressing the defroster into the instrument panel and fixing the holding plate, the defroster is attached to the instrument panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A defroster duct mounting structure according to the present invention will be described below based on embodiments shown in the drawings.

In the figure, 1 is an instrument panel, 2 is a front pillar, and near the corners of both sides of the instrument panel 1, air outlets 11 constituting a side defroster are bored.

3 has a nozzle 32 at one end of the bellows-shaped hose 31.
This is a defroster duct that is integrally formed with the following, and is blow molded from synthetic resin material. In the defroster duct 3 shown in the figure, the opening of the nozzle 32 is opened in a diagonal direction with respect to the length direction of the hose 31 to the nozzle 32.
An air conditioner with one end of 1 installed in the car (not shown)
Furthermore, the nozzles 32 are respectively connected to the air outlet 11 to guide the warm air supplied from the air conditioner to the air outlet 11, and the nozzles 32 are connected to the air outlet 11, and the nozzle 32 is connected to the air outlet 11, and the nozzle 32 is connected to the air outlet 11, and the hot air supplied from the air conditioner is guided to the air outlet 11. The air is blown out toward a side window (not shown).

Therefore, the present invention provides a flange 33 at the tip of the nozzle 32 and a protrusion 34 that protrudes toward the hose 31 side, in other words, the opposite side to the opening of the nozzle 32, and engages with the protrusion 34. Engagement hole 40
A frame-shaped presser plate 4 is formed, and the presser plate 4 presses the flange 33 onto the instrument panel 1. By fixing the presser plate 4, the nozzle 32 of the defrost duct 3 is attached to the instrument panel 1. I attached it to 1.

That is, in the embodiment shown in the figure, an outward flange 33 is provided around the outer periphery of the tip of the nozzle 32, and a hemispherical protrusion 34 is formed near the base of the flange 33.

The holding plate 4 shown in the figure has a claw piece 42 protruding from one side of a frame-shaped main body 41 in which the insertion hole 41a of the nozzle 32 is provided, and the other side of the frame-shaped main body 41 is extended to form an extended portion. A pin hole 43 is provided in the through hole 41a, and a surrounding wall 44 surrounding the outside of the nozzle 32 is integrally formed on three sides of the insertion hole 41a.
4, and a guide piece 4 for guiding the nozzle 32 at the free end of the surrounding wall 44.
5 is provided.

In order to connect the nozzle 32 to the air outlet 11 of the instrument panel 1, first, the presser plate 4 is fitted onto the nozzle 32, and the frame-shaped main body 4 is
1 is applied to the back surface of the flange 33 formed on the nozzle 32, and the protrusion 34 is fitted into the engagement hole 40.

Then, align the opening of the nozzle 32 with the air outlet 11, engage the claw piece 42 with the engagement groove 12 provided on the back surface of the instrument panel 1, and insert the tatu pin screw 10 into the pin hole provided on the panel 1. (not shown) is screwed into a pin hole 43 formed in the presser plate 4 to fix the presser plate 4 to the back surface of the instrument panel 1. Flange 33 of nozzle 32
By holding down the nozzle 3 by the frame-shaped main body 41 of the holding plate 4 and the instrument panel 1, the nozzle 3
2 is attached to the instrument panel 1.

In the present invention, the nozzle 32 of the defroster duct 3 is attached to the instrument panel 1 as described above. The nozzle 32 is held between the instrument panel 1 and the frame-shaped main body 41 of the presser plate 4 fixed to the panel 1.
Since the protrusion 34 formed in is fitted into the engagement hole 40 of the presser plate 4, the mounting position of the nozzle 32, in other words, the opening of the nozzle 32 is aligned with the air outlet 1.
There is no deviation from 1.

As explained above, according to the present invention, the nozzle of the defroster duct can be fixed to the instrument panel by simply fixing the presser plate to the instrument panel by pressing the flange of the nozzle against the instrument panel. It can be easily and securely installed on the instrument panel, and even if tensile force is applied to the nozzle part due to the piping of the defroster duct, the installation position of the nozzle will not shift or the nozzle will be removed from the instrument panel. There is no leaving.
