In particular, it relates to a nozzle that is useful for attaching a nozzle to the rear window of an automobile.

[Conventional technology]

As a conventional device of this kind, for example,
There is a washing nozzle mounting device for an automobile described in Japanese Patent No. 9053.

As shown in FIG. 3, this washer nozzle attachment device is attached to a tailgate or other vehicle body member 3 consisting of an inner plate 1 and an outer plate 2, with a liquid supply port 4 fitted and connected to the inner plate 1. and an injection nozzle 5 that is fitted and connected to the outer plate 2, the hermaphroditic portion extending longitudinally of the liquid supply port 4 and the injection nozzle 5 outwardly and inwardly, respectively. 4a and 5a are fitted together.

[Problem that the invention attempts to solve]

However, in such a washer nozzle mounting device, the liquid supply port 4 and the injection nozzle 5 are fitted inside the tailgate 3, so if the washing liquid leaks from the fitting part, the washing liquid will leak into the tailgate. There is a risk of rust forming inside the tailgate.

An object of the present invention is to provide a washer nozzle mounting device that can prevent rust from forming inside a window frame member (tailgate) formed in a box structure.

[Means for solving problems]

A washer nozzle attachment device according to the present invention is a washer nozzle attachment device for attaching a nozzle to a hinged window body, and includes a washer nozzle attachment device that is integrally molded from an elastic material to a window frame member that is a part of the window body and is formed in a box structure. A joint member is disposed to pass through the pair of opposing walls of the window frame member, and a pair of grommets are formed on the outer periphery of the joint member so as to fit into the through holes in both walls. The nozzle is fitted to a molding member of the window body, and is also fitted to and connected to one end of the joint member.

[Effect]

According to the above-mentioned means, since the nozzle is fitted to one end of the joint member on the outside of the window frame member formed in a box structure, it is possible that the cleaning liquid leaks from the fitting part between the nozzle and the joint member. Even so, the cleaning liquid will not accumulate inside the window frame member, and the occurrence of rust due to this will be prevented.

〔Example〕

FIG. 1 is a side sectional view showing a wash nozzle attachment device which is an embodiment of the present invention, and FIG. 2 is an enlarged partial sectional view taken along the line - in FIG.

In this embodiment, this washer nozzle attachment device is configured to attach the nozzle to the rear window of an automobile.
The window 12 is disposed at the rear of the roof panel 11 of the automobile body so as to open and close in the vertical direction, and is rotatably supported by a hinge portion (not shown). The rear window 12 includes a tailgate 13 as a window frame member, and the tailgate 13 is formed into a box shape with an inner plate 14 and an outer plate 15 as a pair of opposing walls placed together. A roof molding 16 formed in a band shape using resin or the like is arranged along the upper edge of the tailgate 13, and this roof molding 16 is fixed to the tailgate 13 with a clip (not shown). It's becoming like that.

In the figure, reference numeral 17 denotes a rear window glass, which is supported by the tailgate 13 and decorated by the roof molding 16. Further, 18 is a sealing member which is sandwiched between the tailgate 13 and the roof panel 11 when the rear window 12 is closed.

Inner plate 14 of tailgate 13 according to the above configuration
A pair of mounting holes 19 and 20 are provided in the outer panel 15.
Mounting holes 20 (hereinafter referred to as outer mounting holes) formed in the outer panel 15 are arranged concentrically to face each other at approximately the center in the left-right direction on the upper end side of the tailgate 13. The inner diameter is set to be larger than the inner diameter of a mounting hole (hereinafter referred to as an inner mounting hole) 19 formed in the inner plate 14.

A nozzle is fluidly connected to the tailgate 13, and a joint member 21 for holding the nozzle is fitted from the outside into both mounting holes 19, 20 and is fixedly attached. The joint member 21 is integrally molded into a generally cylindrical shape using an elastic member such as rubber or resin, and the joint member 21 has an insertion opening 22 at the outer end thereof in a hollow portion 21a of the joint member 21.
The liquid supply tube (not shown) is provided with an elbow-shaped fitting opening 23 at its inner end. A pair of grommets 24 and 25 are disposed on the outer periphery of the intermediate portion of the joint member 21 at positions corresponding to the height positions of the inner plate 14 and outer plate 15 of the tailgate 13, respectively, and protrude in a circular ring shape. Both grommet portions 24 and 25 are fitted into the inner attachment hole 19 and the outer attachment hole 20, respectively.

The inner grommet portion 24 is an inner flange 24a.
, an outer flange 24b, and an annular groove 24c formed between both flanges 24a and 24b, and these 24a, 24b, and 24c are arranged concentrically. Further, the outer diameter of the inner flange 24a is slightly larger than the inner diameter of the inner mounting hole 19, and the root diameter of the groove bottom of the annular groove 24c is approximately equal to the inner diameter of the inner mounting hole 19.
The outer diameter of the inner flange 24b is larger than the outer diameter of the inner flange 24a. Therefore, when the inner grommet portion 24 is fitted into the inner mounting hole 19 from the outside, the inner flange 24a passes through the inner mounting hole 19, but the outer flange 24b cannot pass through the inner mounting hole 19, so both flanges 24a and 24b are the opening edges of the inner mounting hole 19 which are sandwiched from the inside and outside.
This ensures reliable sealing and fixes the joint member 21 to the inner plate 14. Further, in this state, the annular groove 24c is fitted into the inner periphery of the inner attachment hole 19 at the groove bottom periphery in a compressed and deformed state.

On the other hand, the outer grommet portion 25 has an inner flange 25a and an outer flange 25b adjacent thereto.
These flanges 25a, 25b
are arranged concentrically. Further, the outer diameter of the inner flange 25a is approximately equal to the inner diameter of the outer mounting hole 20, and the outer diameter of the outer flange 25b is set to be larger than the inner diameter of the outer mounting hole 20, respectively. Therefore, when the outer grommet portion 25 is fitted into the outer mounting hole 20 from the outside, the inner flange 25a is fitted into the outer mounting hole 20 in a compressed state, but the outer flange 25b is fitted into the outer mounting hole 20. Therefore, it is pressed against the outer surface of the opening edge of the outer mounting hole 20. In this state, the outer grommet portion 25 reliably seals the outer mounting hole 20, and also connects the joint member 21 to the outer plate 1.
It will be fixed at 5.

Here, as described above, since the inner diameter of the outer mounting hole 20 is set larger than the inner diameter of the inner mounting hole 19, the outer diameter of both flanges 25a, 25b of the outer grommet portion 25 is set as follows. Both flanges 24 of the inner grommet portion 24
The outer diameter is set to be larger than the outer diameter of the annular groove a, 24b and the annular groove 24c. Therefore, in the work of pushing the joint member 21 into the inner mounting hole 19 and the outer mounting hole 20, the operator must press the inner grommet portion 24.
With the side facing forward, insert the joint member 21 into the outer mounting hole 2.
0 and into the inner attachment hole 19, the work can be carried out easily and accurately.

This is particularly advantageous in the push-in operation when there is a misalignment error between the inner mounting hole 19 and the outer mounting hole 20. In such a case, the inner grommet portion 24 may When the outer grommet portion 25 is fitted into the hole 19 and the outer mounting hole 20, the joint member 21
The misalignment error between the holes 19 and 20 is absorbed by the elastic deformation of the intermediate portion. Therefore, the strictness of the processing accuracy of the inner attachment hole 19 and the outer attachment hole 20, the assembly accuracy of the tailgate 13, etc. can be relatively relaxed.

The roof molding 16 as a molding member has a nozzle mounting hole 26 that is similar to the mounting hole 1 of the tailgate 13.
9 and 20, and a nozzle 27 is fitted into this attachment hole 26 from the outside and fixedly attached. The nozzle 27 includes a main body 28 that is integrally molded using resin or the like into a roughly turret shape.
9 have been established. A nozzle tip 30 is embedded in one end surface of the main body 28 so as to communicate with the liquid supply path 29.
It is constructed so that it can be sprayed towards. A communication pipe portion 31 is arranged approximately at right angles and integrally protrudes from the lower surface of the main body 28, and a hollow portion 31a of this pipe portion 31 communicates with the liquid supply path 29. An insertion section 32 is formed at the lower end of the connecting tube section 31 in a tapered shape that gradually becomes thinner as it goes forward, and forms a locking section 33 at its upper end.

A pair of locking claws 34 are provided at the upper end of the communication pipe portion 31.
They are arranged in a symmetrical shape and protrude integrally, and both locking claws 34 are inserted into the nozzle mounting hole 26 of the roof molding 16 after passing through the hole 26 when the connecting pipe portion 31 is inserted from the outside. By expanding and engaging the lower surface of the opening edge of the mounting hole 26, the opening edge of the mounting hole 26 is held between the lower end of the nozzle body 28, and the nozzle 27 is attached to the roof molding 1.
6 is fixedly attached.

When the roof molding 16 to which the nozzle 27 is fixed is fixed to the tailgate 13 with a clip,
The communication pipe portion 31 of the nozzle 27 is inserted into the insertion opening portion 22 of the joint member 21. At this time, since the insertion port portion 22 is formed in a truss shape and the insertion portion 32 of the communication tube portion 31 is formed in a tapered shape, the communication tube portion 31 is reliably received into the insertion port portion 22. . When the insertion section 32 at the lower end of the communication pipe section 31 is inserted into the insertion opening section 22, the locking section 33 on the outer periphery of the insertion section 32 is inserted into the insertion opening section 22.
Since it bites into the inner circumferential surface, the connecting pipe portion 31 is reliably prevented from coming off by the joint member 21. In this state, the liquid supply path 29 of the nozzle 27 is connected to the hollow part 21a of the joint member 21 via the hollow part 31a of the connecting pipe part 31.
is fluidly coupled to.

Next, the action will be explained.

Cleaning liquid (not shown) supplied from a liquid supply tube connected to the attachment port 23 of the joint member 21
When the water is fed to the nozzle 27 through the hollow part of the joint member 21 and the connecting pipe part 31, it is sprayed from the nozzle tip 30 toward the window glass 17.

At this time, even if the cleaning liquid leaks from between the insertion port 22 of the joint member 21 and the insertion portion 32 of the connecting pipe portion 31, the insertion port 22 and the insertion portion 32 are Since the gate 13 is fitted to the gate 13 so as to pass through the inner mounting hole 19 and the outer mounting hole 20, it is located substantially in the external space of the tailgate 13. There will be no intrusion inside.

Furthermore, as shown by the solid line arrow in FIG.
Rainwater, etc. that entered from between the tailgate 1 and the leaked cleaning liquid leaked from between the mating surfaces of the joint member 21 and the inner mounting hole 19 and the outer mounting hole 20.
3, but as mentioned above, these mating surfaces are reliably sealed by the inner grommet portion 24 and the outer grommet 25 respectively formed on the outer periphery of the joint member 21. No flooding will occur.

In this way, according to the present embodiment, water intrusion into the tailgate 13 is reliably prevented, so that water accumulation in the tailgate 13 and rusting are prevented. .

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be modified without departing from the gist thereof.
It goes without saying that various changes are possible.

For example, the joint member is not limited to being configured to be connected to the liquid supply tube, but may be configured to be integrally formed at the tip of the liquid supply tube.
