Magnetic threshold construction

Claim 2

A threshold assembly comprising: a. a horizontally extending leg member, b. a vertically extending leg member formed integrally with said horizontally extending leg member, c. means for attaching said vertically extending leg member to a vertically extending surface of a door, d. means defining a channel in said horizontally extending leg member, e. a mounting flange received in said channel, f. resilient connecting members extending from said mounting flange, g. means defining an elongated pocket attached to said connecting members and extending in spaced, substantially parallel relationship to said mounting flange, h. a threshold plate formed of a nonferrous material, i. means for attaching said threshold plate to a door sill in opposition to said leg member, j. means defining a groove extending longitudinally of said threshold plate, and k. magnetic and magnetically attracted means mounted in said pocket and slot in opposition to each other when said leg member is positioned over said threshold plate, l. said channel in said horizontally extending leg member being angularly disposed with respect to the horizontal whereby said pocket is free of substantial contact with said threshold until said pocket pivots into engagement with said threshold when brought into position thereover.

Claim 3

The assembly of claim 1 wherein: a. said magnetic means is mounted in said pocket, and b. said magnetically attracted means is mounted in said slot.

Claim 4

The assembly of claim 1 wherein: a. said magnetic means is mounted in said slot, and b. said magnetically attracted means is mounted in said pocket.

Claim 5

The assembly of claim 1 wherein: a. a strip of ferrous material is positioned in laminar relationship to said magnetic means.

Claim 6

The assembly of claim 1 wherein: a. said resilient connecting members comprise a pair of reversely pleated members extending between and interconnecting said mounting flange and said pocket.

Claim 7

A threshold assembly comprising: a. a door having a substantially horizontally extending lower edge, b. a substantially horizontally extending leg positioned beneath said lower edge in substantially paralLel relationship thereto, c. an upstanding vertical leg extending from one edge of said horizontally extending leg, d. means attaching said vertical leg to said door, e. a pair of downwardly and inwardly extending, oppositely facing, substantially L-shaped members defining a substantially T-shaped channel having a base angularly disposed with respect to said horizontally extending leg, f. a substantially planar mounting flange snugly received within said channel, g. means defining an elongated pocket extending in spaced, substantially parallel relationship to said mounting flange, h. an elongated, flexible magnet received in said elongated pocket with a strip of ferrous material positioned in overlying, laminar relationship thereto, i. a pair of resilient, reversely pleated connecting members extending between and interconnecting said mounting flange and said pocket, j. a doorsill positioned beneath said lower edge of said door, k. a stationary threshold plate attached to said doorsill, l. a pair of downwardly, inwardly and oppositely facing flanges extending beneath an upper surface of said threshold plate and defining a longitudinally entending groove, and m. an elongated strip of ferrous material received in said groove, n. said channel in said horizontally extending leg member being angularly disposed with respect to the horizontal whereby said pocket is free of substantial contact with said threshold until said pocket pivots into engagement with said threshold when brought into position thereover.

Claim 8

A threshold assembly comprising: a. a door having a substantially horizontally extending lower edge, b. a substantially horizontally extending leg positioned beneath said lower edge in substantially paralLel relationship thereto, c. an upstanding vertical leg extending from one edge of said horizontally extending leg, d. means attaching said vertical leg to said door, e. a pair of downwardly and inwardly extending, oppositely facing, substantially L-shaped members defining a substantially T-shaped channel having a base angularly disposed with respect to said horizontally extending leg, f. a substantially planar mounting flange snugly received within said channel, g. means defining an elongated pocket extending in spaced, substantially parallel relationship to said mounting flange, h. an elongated, flexible magnet received in said elongated pocket with a strip of ferrous material positioned in overlying, laminar relationship thereto, i. a pair of resilient, reversely pleated connecting members extending between and interconnecting said mounting flange and said pocket, j. a doorsill positioned beneath said lower edge of said door, k. a stationary threshold plate attached to said doorsill, l. a pair of downwardly, inwardly and oppositely facing flanges extending beneath an upper surface of said threshold plate and defining a longitudinally entending groove, and m. an elongated strip of ferrous material received in said groove, n. said channel in said horizontally extending leg member being angularly disposed with respect to the horizontal whereby said pocket is free of substantial contact with said threshold until said pocket pivots into engagement with said threshold when brought into position thereover.
