Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a defroster nozzle formed by injection molding of synthetic resin for use in automobiles and the like.

Conventional technology The conventional defroster nozzle
As stated in the publication (especially Figure 5),
The defroster is constructed by forming rivet locking portions at both ends of one longitudinally long defroster body that is formed into two parts, and forming rivet locking holes at both ends of the other longitudinally long defroster body. There is one in which the locking parts at both ends of the main body are locked into the locking holes.

Another conventional defroster nozzle was developed in 1978.
As described in Japanese Utility Model Application No. 56-194329 (specification and drawings), there is a rib (support protrusion) inside the air outlet of one longitudinally long defroster body formed in two parts. At the same time, a locking recess is formed at the upper end of the air outlet, and an elongated piece (locking piece) is formed at the upper end of the air outlet of the other defroster body which is long in the longitudinal direction. There is one in which a long strip is locked in a locking recess.

Problems to be Solved by the Invention In the former conventional defroster nozzle in which both ends of the defroster body are locked with a locking part and a locking hole, the upper air outlet is long in the longitudinal direction. The drawback is that molding deformation and thermal deformation easily occur at the top air outlet, so there is a gap at the abutment part of the wind direction adjustment plate, especially the middle part that is long even if only both ends of the defroster body are long in the longitudinal direction. In this case, molding deformation and thermal deformation occur more greatly,
There was a drawback that a large gap was created by the abutment part of the wind direction adjustment plate.

And in the latter conventional defroster nozzle,
This is because the air-conditioning air blown out from the rib (supporting protrusion) formed inside the outlet rather than at the upper end of the outlet hits the strip of locking strip formed at the upper end of the outlet, creating turbulence. However, it has the disadvantage that it reduces the ability to clear the windshield of a vehicle.

This invention eliminates the above-mentioned drawbacks of conventional defroster nozzles, corrects the deformation of the top outlet of the defroster nozzle before assembly, and prevents the top outlet from deforming after assembly. The purpose of this is to prevent gaps from forming at the abutting portion of the wind direction adjustment plate, and to improve the ability to clear the windshield of a vehicle.

Means for Solving the Problem The defroster nozzle of this invention has the upper end of the defroster main body and the upper end of the airflow direction adjusting plate at the same height on one side or both sides of the nozzle part of the defroster main body which is divided vertically into two along the longitudinal direction. At the same time, a connecting member is integrally formed on the side end surface of at least one part of the wind direction adjusting plate, and a connecting member is integrally formed on the side end surface of at least one part of the wind direction adjusting plate, and a corresponding one on the other side of the nozzle part is formed. An insertion hole is formed at a location, and a connecting member is inserted into the insertion hole and locked with a locking part provided at the tip of the connecting member, and then both ends of one defroster main body, which is formed into two parts. A locking portion is formed in the defroster body, a locking hole is formed in both ends of the other defroster main body, and the locking portion is fitted into the locking hole to be assembled and integrated.

Function The defroster nozzle of this invention has a connecting member formed protruding from the side end surface of the air direction adjusting plate integrally formed on one or both sides of the nozzle part of the defroster body divided into two parts, and the connecting member is inserted into the insertion hole on the other side of the nozzle part. Insert and lock with the locking part provided at the tip of the connecting member, and then form the locking parts at both ends of one defroster body formed in two parts, and form the locking parts at both ends of the other defroster body. By forming a locking hole and locking the locking part into the locking hole and assembling it into one piece, the upper surface outlet of the defroster nozzle is corrected if it has already been deformed before assembly, and the defroster nozzle To prevent deformation of the upper surface air outlet part of the windshield, to eliminate gaps at the abutting part of the wind direction adjustment plate, and to improve the clearing performance of the windshield of the vehicle.

Rear defroster body 3 on the other side of nozzle part 4
An insertion hole 8 is formed at a corresponding location on the upper side wall of the housing. Locking pawls 10 are provided at both ends of the front defroster body 2, and locking holes 12 are provided at both ends of the rear defroster body 3. Furthermore, locking claws 10 are provided at predetermined locations on the edge 2' of the front defroster body 2 and on the mating flange portion 9, and at predetermined locations on the edge 3' of the rear front defroster body 3 and on the mating flange portion 11. A locking hole 12 is provided.

Connect the locking claws 10 provided at both ends of the front defroster body 2 to the rear defroster body 3.
The two divided defroster bodies 2 and 3 are inserted into locking holes 12 provided at both ends of the defroster main body 2 and 3, and are assembled into one body at both ends. At the same time, the locking portions 7 of the connecting members 6 formed on every other wind direction adjusting plate 5 provided on the front defroster body 2 are inserted into the insertion holes 8 formed in corresponding locations on the upper side wall of the rear defroster body 3. This is a defroster nozzle 1 that is integrated with the flange so that the connecting part is hidden under the flange.
