Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a synthetic resin louver equipped with a mesh body, which can be attached to an outside air inlet into a car interior to remove dust, powdered snow, etc. from inside the car interior. It is used mainly in the automobile industry.

<Prior Art> There is already a concept of attaching a net to the louver that introduces outside air into the interior of an automobile. The conventional means for attaching the net to the louver is, for example, Nos. 4A and 4.
As shown in Figures B and 4C, the frame-shaped resin louver body 1 is provided with a grid 2 that allows small foreign objects to pass through, and is provided with a locking piece 6 for attachment to the outside air inlet, and a grid on the air discharge side. The entire circumference of the net body 7 was welded to the top.

<Problems to be Solved by the Invention> In the conventional device as described above, the ends of the net are welded all around, resulting in poor processing efficiency, time consuming, and high assembly costs.

When the net body was assembled to the resin louver body, the cut ends of the net were visible, resulting in an unsightly appearance.

When the mesh body is made of wire mesh, the terminal may protrude from the product and may become stuck if the wire mesh is held by hand, which is dangerous.

When the mesh was welded to the louver body, resin was visible in the melted mesh due to welding, resulting in an unsightly appearance.

<Means and actions for solving the problem> In order to eliminate or improve the above-mentioned defects, ribs are provided on the frame-shaped synthetic resin louver body so as to surround the edges of the mesh, and the mesh is also placed inside the ribs. A shelf was provided to support the end periphery, welding bosses were provided at appropriate positions on the shelf, and the net was attached to the shelf at appropriate locations on the shelf so as to be surrounded by ribs.

Because of the ribs, the mesh body could be easily positioned during installation, and the periphery of the mesh body could be prevented from protruding from the louver body. In addition, since the mesh is welded by bosses placed on the shelf at appropriate intervals, installation efficiency is higher than by welding all the way around, and the shelf prevents molten resin from flowing out and functions as a support surface for the mesh. .

<Example> As shown in FIGS. 1A, 1B and 2, a rectangular louver main body 1 has locking pieces 6 at approximately four corners of a picture frame and has a grid of approximately 15 mm in size through which small foreign objects can pass through the picture frame. is made of synthetic resin, and on the mesh attachment surface (air release surface) of the main body, a lattice section 2 and a shelf 5 surrounding it are placed, and ribs 3 are set upright on the shelf 5.
Welding bosses 4 approximately 10 mm long were provided as strips parallel to the ribs 3 at 30 mm intervals. The mesh 7 used has a mesh size of about 1 mm, which is much finer than a stainless steel grid.

As shown in FIGS. 3a to 3e, the mesh body 7 is positioned within the rib 3 of the louver body 1 (Figure a), and then brought into contact with the welding boss (Figure b) to heat-fuse the boss, As shown in Figure c, the mesh body 7 was attached to the air discharge side of the grid 2 so as to be in contact with it.

The obtained louver has ribs 3 all around the edge of the net 7.
Since the net 7 is surrounded by the main body 1, the net 7 does not protrude beyond the main body 1, and the unsightly appearance of uneven edges of the net can be hidden.

The molten flow from the boss 4 could be received by the shelf 5, and the shelf surface could support the edge of the net without any functional problem, even though it was partially bonded.

The stainless steel mesh has a rust-preventing effect, conforms well to the shape of the main body, and exhibits mechanical strength and shape retention.
In addition to being able to paint with any color, it was also possible to attach it to the louver body using ultrasonic caulking.

In the above embodiment, the ribs 3 and shelves 5 are applied all around the main body 1, but even if the present invention is implemented by applying these only to the main part of the louver main body, the same effect will be achieved. It will be obvious to those skilled in the art that even if the shape of the welding boss is appropriately modified (for example, into an uneven shape or a prismatic shape), the same effect can be achieved and the same is within the scope of the present invention.

<Effects of the invention> Since the welding boss is used to firmly weld, there is no need to glue the entire periphery of the mesh, streamlining the welding process.

Furthermore, due to the presence of the shelf, even if the welding boss melted and flowed, the louver did not have any problem, and the edge of the mesh which was intermittently bonded could be stably supported. Since the edges of the net were protected by ribs, there was no danger of holding the louver body in the hand, and the appearance of the edges of the net was improved.
