Abstract
A weather strip in particular for window and door frames having a base portion (2) arranged to be engaged in a respective anchoring area (3) of a first bearing frame (4). A head portion (5) of the weather strip is arranged to act against an abutment area (6) associated with the a second bearing frame (7). A band of magnetic material (8) is associated with the head portion, and there is an intermediate connecting portion (9) formed, in transverse section, by a single fillet element connecting the head portion with the base portion.
Claims15
A weather strip for window and door frames, comprising:
- a base portion (2) arranged to be engaged in an anchoring area (3) of a first bearing frame (4);
- a head portion (5) having at least one operating holding area (5b) to act against and abutment area (6) associated with a second bearing frame (7);
- a band of magnetic material (8) in a longitudinal seat (5a) formed in said head portion (5);
- and
- a non-tubular intermediate connecting portion (9) between said base and head portions, said intermediate portion (9) in section is defined by a single fillet element having at least one unstraight bendable portion (9a) in the form of an arc and a substantially straight portion (9b), said bendable portion extending substantially centrally from said head portion, said straight portion extending from only one side of said base portion, said straight portion has a gradually decreasing thickness away from said base portion, said fillet elements is capable of bending and extending to move the head portion (5), along any direction, from a rest position to a plurality of operating positions located at a given distance from said rest position and the magnetic charges of said band are disposed in such a manner that the opposite poles are located at the opposite ends of said operating holding area (5b) and are adapted to act on a magnetic element arranged on the abutment area (6), said head portion and said base portion being interconnected only by said fillet element.

A weather strip for window and door frames comprising:
- a base portion (2) adapted to be engaged in an respective anchoring area (3) of a first bearing frame (4);
- a head portion (5) having at least one operating holding area (5b), said holding area (5b) adapted to act against an abutment area (6) on a second bearing frame (7);
- a band of magnetic material (8) connected to said head portion (5);
- and
- a non-tubular intermediate connecting portion (9) between said base portion and said head portions, said intermediate portion (9) having a single first terminal area integral to only one side of the base portion and a single second terminal area integral to only a central portion of the head portion, said intermediate portion in transverse section being a single fillet element extending between said first and second terminal areas on said element having at least one unstraight bendable portion (9a) in the form of an arc and a substantially straight portion (9b), said bendable portion extending substantially centrally from said head portion, said straight portion extending from only one side of said base portion, said straight portion has a gradually decreasing thickness away from said base portion, said bendable portion providing movement of said head portion (5), along any direction, from a rest position to a plurality of operating positions located at a given distance from said rest position and the magnetic charges of said band being disposed in such a manner that opposite magnetic poles of said band are located at the opposite ends of said operating holding area (5b) to act on a magnetic element on the abutment area (6), said head portion and said base portion being reciprocally connected by only said intermediate portion (9).
