Description

[Detailed Description of the Invention] This invention relates to a gap shielding material, and more particularly, to a gap shielding material for filling gaps that occur at the opening and closing ends of things that are opened and closed, such as windows and doors.

Conventionally, tapes made of urethane foam or PET rubber foam have been widely used to close gaps that occur at the opening and closing edges of windows and doors, with an adhesive layer attached to the end surfaces of windows and doors. However, the above-mentioned foam tapes for gap-shielding are designed to have a certain thickness so as to be able to cope with the gaps that occur in non-uniform conditions. As mentioned above, the closed window D may open due to the restoring elastic force of the tape T between the gaps S, and the gaps S may not be completely closed.

In view of the above-mentioned drawbacks, this invention provides a gap shielding material that completely closes gaps of any shape and does not reopen due to elasticity even after closing a window. This is a soft metal elongated body formed into a thin hollow shape with a flat cross-sectional shape, and has an adhesive layer on one flat outer surface, and on the other outer circumferential surface, At least the other flat outer surface is provided with an elastic foam layer.

This invention will be explained below using examples.

Figure 2 is an enlarged sectional view of an embodiment of this invention;
The figure is a perspective view of the embodiment.

As shown in FIG. 2, the gap shielding material A of this invention adheres to the outer surface of one flat surface 1A of a long body 1 made of soft metal, e.g., soft aluminum, and formed into a thin hollow shape with a flat cross-sectional shape. The agent layer 2 is configured such that an elastic foam layer 3 is provided on at least the other outer peripheral surface of the flat surface 1B.

Although the soft metal elongated body 1 has an oval cross-sectional shape in the above embodiment, the cross-sectional shape is not limited to this, and the cross-sectional shape may be flat as shown in FIGS. 4 and 5.

To use the gap shielding material A of this invention, as shown in FIG. It closes.

At this time, the gap shielding material A is pushed by the window 5 and deformed as shown in Fig. 7, but since it is made of soft metal, it deforms easily and this deformation becomes a permanent deformation, so that it is not closed. No force is generated to push the rear window door open.

Therefore, it deforms into a shape that follows the shape of the gap, and in cooperation with the foam layer 3 provided on the outer surface, the gap is completely closed.

Since this device is constructed as described above, it can easily be permanently deformed to accommodate gaps of various shapes, so unlike urethane foam tape, the window cannot be pushed open again due to its elastic restoring force. It has practical effects such as being able to completely close the gap and being easily manufactured by continuous extrusion or the like, so that it can be provided at a low cost.
