Description

[Detailed explanation of the invention] This invention is a defroster that is installed at the bottom of the window glass of a car to remove or prevent fogging that occurs on the inner surface of the window glass during winter or rainy weather and to prevent snow, etc. from freezing in cold regions. Regarding nozzles.

The defroster nozzle is usually disposed inside the instrument panel, and has an air outlet opening on the top surface of the instrument panel toward the front windshield.

For this reason, there is a risk that foreign matter may fall from the air outlet into the nozzle, and as a countermeasure for this, conventionally the air outlet C of the defroster nozzle b is located on the top surface of the instrument panel a, as shown in Figures 1 to 3. A wire mesh d can be tightened with screws e to the part, a wire mesh d can be glued or heat-sealed f to the air outlet e of the defroster nozzle b molded from plastic, or a wire mesh d can be attached to the air outlet e of the defroster nozzle b. Opening g of instrument panel a provided
The wire mesh d was glued from the inside, but fixing the wire mesh with screws spoils the appearance, and gluing or heat-sealing requires adhesive or special heating equipment, and in either case, it is difficult to fix the wire mesh. This requires a lot of man-hours and is unavoidably disadvantageous in terms of cost.

This idea was made in view of the above points, and its purpose is to create a net that prevents foreign objects from falling into the nozzle without damaging the appearance and without requiring adhesive or special heating equipment. To provide a defroster nozzle which can be extremely easily fixed.

The embodiment of this invention will be explained in detail with reference to the drawings below.
As shown in FIG. 4, the defroster nozzle 1 has a cylindrical lower part and a fan shape with a flat upper part, and has a defroster duct connection port 2 at the lower end and an air outlet 3 at the upper end.

This defroster nozzle 1 is made of plastic material and is divided into front and rear parts, which are molded separately, and then assembled together after molding.

For this purpose, a pair of separately molded defroster nozzle front plate 1a and defroster nozzle rear plate 1b have flanges 4a and 4 on both side peripheries, respectively, as shown in FIGS. 5 and 6.
b, and one flange 4a is provided with an appropriate number of locking pawls 5, and the other flange 4b is provided with a locking hole 6 in which the locking pawl 5 can be locked at a location corresponding to the locking pawl 5. establish.

One of the defroster nozzle front plates 1a and 1b includes a seventh defroster nozzle in the vicinity of the air outlet 3.
As shown in the figure, a plurality of upper and lower lips 7.8 are provided protruding from the inner surface of one defroster nozzle front plate 1a toward the opposing inner surface of the other defroster nozzle rear plate 1b.

The lip 7.8 is spaced so that a mesh body 11, which will be described later, can be inserted between the lips 1 and 8, and the length of the lip 7.8 is such that when the defroster nozzle front plate 1a and rear plate 1b are assembled, the tip of the lip 7.8 is The length is such that it almost reaches the other opposing defroster nozzle rear plate 1b.

In this embodiment, a pair of upper and lower lips 7°8 are provided at five locations near the air outlet 3 on the front plate 1a of the defroster nozzle, of which three in the center are provided on the upper side as shown in FIGS. 8 and 9. A locking pawl 9 is further provided at the tip of the lip 7, and a locking hole 10 into which the locking pawl 9 can be locked is provided in the defroster nozzle rear plate 1b opposite to this at a location corresponding to the locking pawl 9.

Therefore, a pair of upper and lower lips 7 of the defroster nozzle front plate 1a
．． 8, insert a metal mesh body 11 that matches the cross-sectional shape of the air outlet 3 of the defroster nozzle 1, then align the front and rear plates 1a and 1b of the defroster nozzle, and insert the locking pawl 5 of the flange 4a into the locking hole 6 of the flange 4b. The defroster nozzle front plate is fitted and locked using the elasticity of plastic, and the locking claw 9 provided at the tip of the lip 7 is similarly fitted and locked into the locking hole 10 of the defroster nozzle rear plate 1b. The defroster nozzle 1 is formed by assembling the rear plate 1a and the rear plate 1b, and at the same time a mesh body 1 is installed so as to block the air outlet 3.
1 can be fixed.

That is, the pair of upper and lower lips 7.8 clamp the net body 11 and restrict its movement in the vertical direction, and the movement in the front, rear, left, and right directions is restricted by the defroster nozzle front plate la and rear plate 1b themselves.
This holds the mesh 11 securely in place.

This makes it possible to reliably prevent foreign matter from falling into the defroster nozzle 1.

A locking pawl 9 provided at the tip of the lip 7 prevents deformation of the air outlet 3 of the defroster nozzle 1, particularly in the expansion direction.

In this invention, the locking pawl 9 is not necessarily required.

In the above embodiment, the defroster nozzle front plate 1a and the rear plate 1b
A pair of upper and lower lips 7 are attached to one defroster nozzle front plate 1a.
．． 8 is shown as protruding, but the present invention is not limited to this. For example, as shown in FIG. Lips 8 may be provided separately on the defroster nozzle front plate 1a, and as shown in FIG. The defroster nozzle front plate 1a and the rear plate 1b may be provided with short upper lips 7a and 7b facing each other, in other words, the defroster nozzle front plate 1a and the rear plate 1b are assembled. Any material may be used as long as it can hold the net body 11 when combined.

Of course, the upper and lower pairs of lips 7.8 can also be shifted in position in the left-right direction.

Furthermore, in the assembly of the defroster nozzle front plate 1a and rear plate 1b, the respective flanges 4a and 4b are generally It can also be assembled by adhesive or mechanical bonding means.

The defroster nozzle of this invention can be widely used as a defroster nozzle not only for automobile front windshields, but also for side window glasses, rear window glasses, etc.

As described above, this invention is based on a defroster nozzle for an automobile that is formed by assembling a front plate and a rear plate that are formed separately into two parts, and a pair of upper and lower lips are installed on the inner surface near the air outlet of the defroster nozzle. A plurality of these are provided on one or both of the front plate and the rear plate, protruding from one inner surface toward the opposite surface of the other, and a net body that matches the cross-sectional shape of the air outlet is sandwiched between the upper and lower lips. Before assembling the defroster nozzle front plate and rear plate, the mesh body can be simply inserted into the gap between the upper and lower lips or placed on the top surface of the lower lip to assemble both. By attaching it, the net body is held fixed.

Furthermore, since the lip is provided inside near the air outlet, the outlet does not bulge outward and its external shape is minimized, so that the installation space in the vehicle interior can be reduced.

Furthermore, unlike conventional methods, adhesives and special heating devices are not required for fixing the net, and the net can be extremely easily fixed at the same time as the assembled pair of defroster nozzle plates. The number of man-hours required for fixing is almost nil, and the resulting mesh body only needs to be processed into a simple external shape, which can significantly reduce costs and further improve the appearance.

In addition, when the length of the lip provided on one of a pair of defroster nozzle plates is set to reach the other defroster nozzle plate as in the example, it is necessary to prevent the air outlet of the defroster nozzle from being deformed by hot air. can be prevented,
Similar effects can be obtained when a highly rigid metal net is used as the ordinary net.
