Abstract

A fastening assembly for attaching a ferrous metal baking pan to a baking rack, the baking rack having a plurality of bars, the fastening assembly including an “E” plate having a stem and a plurality of arms, a pair of bar receiving channels, the channels consisting of the arms'"'"' interstices; at least a first permanent magnet; and a concavity and seal combination interconnecting the at least first permanent magnet and a medial arm among the “E” plate'"'"'s plurality of arms.

Claims

1. A fastening assembly for attaching a ferrous metal baking pan to a baking rack, the baking rack having a plurality of bars, the fastening assembly comprising:

(a) an “

E”

plate having a stem and a plurality of arms, the arms defining at least a first interstitial space;

(b) at least a first bar receiving channel, said channel comprising the arms'"'"' at least first interstitial space;

(c) at least a first permanent magnet; and

(d) attaching means interconnecting the at least first permanent magnet and an arm among the “

E”

plate'"'"'s plurality of arms.

2. The fastening assembly of claim 1 wherein the “

E”

plate'"'"'s arms define a plurality of interstitial spaces, the arms further defining a second bar receiving channel.

3. The fastening assembly of claim 2 wherein plurality of arms includes a medial arm, and wherein the attaching means comprises a concavity opening at the medial arm, the concavity being fitted for receiving the at least first magnet.

4. The fastening assembly of claim 3 wherein the concavity'"'"'s opening is positioned at the medial arm'"'"'s distal end.

5. The fastening assembly of claim 4 wherein the attaching means further comprises sealing means adapted for closing the concavity'"'"'s opening.

6. The fastening assembly of claim 5 wherein the sealing means comprises a plug or a hardened epoxy resin deposition.

7. The fastening assembly of claim 3 wherein each of the arms has a proximal end, a distal end, and a longitudinal extension, and further comprising a plurality of cross bar retaining ridges, each ridge among the plurality of cross bar retaining being fixedly attached to or wholly formed with the “

E”

plate, and each such ridge being positioned to extend from one of the arms'"'"' distal ends and into one of the bar receiving channels.

8. The fastening assembly of claim 7 wherein the arms'"'"' distal extensions distally oblongated bar receiving channels.

9. The fastening assembly of claim 8 wherein the “

E”

plate comprises a longitudinal extrusion of a thermo-setting material selected from the group consisting of plastics, aluminum, aluminum alloys, copper, copper alloys, brass, and steel.

10. The fastening assembly of claim 4 further comprising a second permanent magnet, and wherein the concavity is further fitted for receiving the second permanent magnet.

11. The fastening assembly of claim 10 wherein the at least first and second permanent magnets are oriented antipodally with respect to each other and further comprising a magnetic armature, the concavity being further fitted for receiving the magnetic armature.

12. The fastening assembly of claim 11 wherein the at least first and second permanent magnets'"'"' orientations distally extend a pair of opposing magnetic poles, and wherein the magnetic armature is positioned to span between said poles.
