DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer hose device for an automobile, which is mounted on a cowl cover of an automobile and transfers a washer fluid to a washer nozzle.

[0002]

2. Description of the Related Art Conventionally, as a technique related to this kind of device,
JP-A-9-175435 or JP-A-11-30
One disclosed in Japanese Patent No. 1425 is known.

In the technique disclosed in the former publication, as shown in FIG. 11, a washer hose insertion portion d is formed by bending a mounting piece c of a cowl top cover b mounted on an upper portion of a cowl top panel a of an automobile. A washer hose e formed separately is inserted through the washer hose insertion portion d, and one end of the washer hose e is fitted to the washer nozzle f attached to the cowl top cover b, and the other end is not shown. It is connected to the connection pipe on the washer tank side, and is intended to reliably and easily position and fix the washer hose d with respect to the cowl top cover b.

In the technique disclosed in the latter publication, as shown in FIG. 12, a washer hose g is integrally formed on a cowl top cover b by a gas injection injection molding method, and the washer hose g is formed. One end is connected to the washer nozzle e and the other end is connected to the connection pipe h on the washer tank side, and is intended to provide a transfer path for the washer liquid with a reduced number of parts.

[0005]

However, both technologies have the following problems, respectively.

That is, in the technique of inserting the washer hose e into the washer hose insertion portion d integrally formed with the mounting piece c of the cowl top cover b of the former publication, the other end of the washer hose e is connected to the washer tank. After fitting into the connecting pipe on the side, the one end side of the washer hose e, which is flexible and hard to locate, is connected to the washer nozzle f while snapping on to the cowl top cover b attached later. This causes the operator to handle the washer hose e which is flexible and difficult to position, and thus complicates the operation.

In the latter publication, the washer hose e is formed integrally with the cowl top cover b using the gas injection molding method because the washer hose e is made of the same material as the cowl top cover b. In addition, due to the nature of the gas injection injection molding method, the molded product becomes a closed hollow body except for the gas injection part, and the washer hose e
Is open at one end, but is closed at the other end, so that there is a problem that it is not easy to attach to the washer nozzle f.

SUMMARY OF THE INVENTION In view of the foregoing, an object of the present invention is to provide a washer hose device for an automobile intended to facilitate a washer hose mounting operation.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a washer hose device for an automobile which is mounted on a cowl cover of an automobile and transfers window washer fluid to a washer nozzle. A tube member made of a flexible soft material and a mounting piece made of a hard material for attaching the tube member to the cowl cover are formed by integral molding.

According to the present invention, the washer hose composed of the pipe member made of a soft material can be connected to the washer nozzle while being integrally formed and supported on the mounting piece made of the hard material. Positioning is reliably performed in the vehicle body assembling process, and the mounting operation is simplified.

Further, the present invention is characterized in that the tube member is separable from the mounting piece after molding, and the separated portion is configured as a mounting portion for the washer nozzle.

According to the present invention, the pipe member constituting the washer hose is partly separated from the mounting piece after molding, so that the pipe member is adjusted to the proper position while adjusting the length thereof in accordance with the mounting position of the washer nozzle. And a pair of washer hoses are usually used in accordance with the washer nozzles installed at two places separated in the vehicle width direction. , And can be used after being cut to an appropriate length after molding, which is advantageous in terms of molding dies and manufacturing costs.

Further, the present invention is characterized in that a seal member for sealing between the cowl cover and the engine hood is formed integrally with the mounting piece portion. Preferably, the seal member extends in the vehicle width direction, for example, so as to fit the engine hood.

According to the present invention, at the same time that the mounting piece is mounted on the cowl cover, the seal member is also mounted on the vehicle body, so that the assembling workability can be improved.

Further, the present invention is characterized in that it is formed by extrusion molding.

According to the present invention, since the pipe member constituting the washer hose is formed by extrusion molding, both ends of the washer hose can be opened, unlike the case where the pipe member is formed by gas injection molding. Therefore, the attachment to the washer nozzle or the washer tank side can be performed as it is without needing another reworking operation, and from this point, the attachment operation can be simplified and the efficiency can be improved.

FIG. 7 is a plan view showing a state where both ends of the washer hose are attached to the washer tank side and the washer nozzle side, respectively. FIG. 7 is a sectional view taken along the line BB of FIG.

First, in FIGS. 1 and 2, a cowl cover 3 is mounted on a cowl top 2 of a vehicle body 1 of an automobile, and a pair of washer hoses 4 and 4 are attached to the cowl cover 3 by mounting pieces 5. It is mounted by mounting using double-sided adhesive tape 15.

The washer hoses 4, 4 are connected at one end to a connecting pipe 8 connected to a washer tank 7.
The other end is mounted on a pair of washer nozzles 9, 9 of the cowl top 2, which are mounted separately from each other in the vehicle width direction of the body 1.

Then, as shown in FIG.
Is mounted on the cowl top 2 with a clip 3a or the like. A wind seal member 11 extends in the vehicle width direction at one end side in the front-rear direction of the vehicle body 1 to form a seal structure with the wind glass 10. At the other end, a mounting piece 5 integrally formed with the washer hose 4 is mounted.

The washer nozzle 9 is attached to the cowl cover 3 by clipping or the like, sprays a washer liquid 12 onto the window glass 10 and operates the wiper blade (not shown) to wipe the window glass 10. .

As shown in FIG. 7, the washer hose 4 is composed of a pair of tubular members molded using a soft and flexible olefin-based elastomer resin. A washer hose 4 is integrally formed on a side wall 5a on the rear side of the vehicle body, and a soft and flexible olefin-based elastomer resin is formed on the upper wall 5b so as to be tubular. The seal member 6 is integrally formed.

The seal member 6 forms a seal structure between the cowl cover 3 and an engine hood (not shown).

As described above, the washer hose 4 is formed integrally with the mounting piece 5, and the seal member 6 is also formed integrally with the mounting piece 5, so that the washer hose 4 is formed. The seal member 6 and the seal member 6 are integrally formed via the mounting piece 5.
