Abstract A magneto-responsive composite molding comprising an elongate casing adapted for operative association with a closure such as a door edge. The casing includes a pair of opposing faces one of which is adapted to contact and be concealed by the a closure or door edge and the other of which is adapted to be exposed relative to the closure or door edge. The composite molding furthermore includes at least one metallic strip which is encapsulated within the casing between the pair of opposing faces of the latter. The metallic strip is constituted of magnetically responsive material for responding to a magnetic force or magnetic forces of a magnetic field provided by a magnetic element mounted in the door frame across which the door edge may be swung.
A composite molding as claimed in claim 1, wherein said second metallic strip is also constituted of magnetically responsive material.
Claim 2
Dependent Claim
19 words
A composite molding as claimed in claim 1, wherein each of said metallic strips is co-extensive with one another.
Claim 3
Dependent Claim
38 words
A composite molding as claimed in claim 3, wherein said metallic strips have a combined width transversely of said opposing faces of said casing substantially greater than that portion of the thermoplastic wherein said exposed other face extends.
Claim 4
Dependent Claim
25 words
A composite molding as claimed in claim 1, wherein said casing is generally U-shaped in cross-section and defined by a pair of integrally interconnected limbs.
Claim 5
Dependent Claim
26 words
A composite molding as claimed in claim 5, wherein one of said limbs has an extent substantially greater than that of the other of said limbs.
Claim 6
Dependent Claim
50 words
A composite molding as claimed in claim 5, in combination with a door edge and door frame across which said door edge may be swung, said limbs being adapted to fixedly embrace said door edge, said door frame including a magnetic element for operative association with said first metallic strip.
Claim 7
Dependent Claim
32 words
A composite molding as claimed in claim 7, wherein said magnetic element extends in said door frame at a position against which the door edge upon which said molding is supported engages.
Claim 8
Dependent Claim
20 words
A composite molding as claimed in claim 8, wherein said casing and said door edge are co-extensive with one another.
