Description

[Detailed Description of the Invention] This invention relates to an extrusion molded product made of a synthetic resin or the like that can be V-cut and easily rounded at the bent corner.

In the extrusion molded product 6 made of synthetic resin etc. as shown in FIG. 1, the extruded product material 1
A sheet 2 made of vinyl chloride or the like is affixed to the outer surface of the frame, and a core material 3 is adhered to fill the hollow space inside the frame, and this is V-cut to form corners such as frames. When the bending is performed, the corner portion 5 is as shown in FIG.
Even if you adjust the remaining thickness when constructing the V-cut, you can only create a radius of about 2 mm or less, and if you try to create a radius larger than this, it may cause the V-cut to break, or the corner 5 There were many cases in which the appearance of the product was significantly deteriorated, resulting in defective products, such as gaps appearing in the material, or whitening of the resin surface caused by forced bending.

This idea was made in view of the current situation, and involves attaching a soft material in advance to the part that will be left unfilled by V-cutting the material, then attaching a sheet, and filling the inside with core material. By providing an extrusion molded product, the purpose is to make it easier to round corners during bending by V-cut construction.

3 and 4 are perspective explanatory views showing an embodiment of this invention. First, the extrusion molded product 7 shown in FIG. After adhering a soft material in advance to the area that will become the remaining flesh, a sheet 2 of vinyl chloride or the like is pasted on the outer surface of the material, and the core material is glued and filled into the hollow space inside. be.

Therefore, the extrusion molded product 7 according to this invention has V.
When cutting and bending, as shown in FIG. 4, if a V-cut is made in the soft material 4 that has been bonded in advance so as to leave the remaining thickness, then the bending is performed on that part. Due to the bending resistance of the soft material 4 bonded to the outside of the material, the corner portion 5 is obtained which is bent while maintaining a gentle large radius without causing the remaining part of the material to bend sharply. Because of this, there are no defects such as cuts, gaps, or whitening that occur with conventional extrusion molded products.

As described above, this invention has the effect of easily forming a large radius by disposing the soft material in advance on the extruded product material, and can prevent the product from becoming defective.
