Fastening device

Claim 2

A construction fastening device of the type which would engage a mating device upon application of engaging means, comprising: (a) a cam device, further comprising: i) a half-circle plate having a front and back side, said plate being rigidly mounted upon an axle; ii) a flange rigidly connected to and extending from both sides of said plate along the full circumference of the plate; iii) a magnetic slug which is rigidly attached to said plate at one end of said flange; (b) a first housing in which said cam device is contained, said housing having two broad sides separated by four narrower sides, one of said narrower sides being opened such that said cam device can extend therefrom when operated, each of said broad sides having a round opening centrally located such that said axle fits loosely thereinto and having a gasket fitted between said axle and opening; (c) means for securing said half-circle plate against said first housing when cam device and mating device are in either the engaged or disengaged position.

Claim 3

A construction fastening device, comprising: (a) a cam device, further comprising: i) a half-circle plate having a front and back side, said plate being rigidly mounted upon an axle; ii) a flange rigidly connected to and extending from both sides of said plate along the full circumference of the plate; iii) a magnetic slug which is rigidly attached to said plate at one end of said flange; (b) a first housing in which said cam device is contained, said housing having two broad sides separated by four narrower sides, one of said narrower sides being opened such that said cam device can extend therefrom when operated, each of said broad sides having a round opening centrally located such that said axle fits loosely thereinto and having a gasket fitted between said axle and opening; (c) a mating locking element; (d) means for rotating said cam device so that said flange may engage or disengage said mating locking element; (e) means for securing said half-circle plate against said first housing when cam device and mating element are in either the engaged or disengaged position.

Claim 4

A construction fastening device, comprising: (a) a cam device, further comprising: i) a half-circle plate having a front and back side, said plate being rigidly mounted upon an axle; ii) a flange rigidly connected to and extending from both sides of said plate along the full circumference of the plate; iii) a magnetic slug which is rigidly attached to said plate at one end of said flange; (b) a first housing in which said cam device is contained, said housing having two broad sides separated by four narrower sides, one of said narrower sides being opened such that said cam device can extend therefrom when operated, each of said broad sides having a round opening centrally located such that said axle fits loosely thereinto and having a gasket fitted between said axle and opening; (c) a mating locking element; (d) means for rotating said cam device so that said flange may engage or disengage said mating locking element; (e) means for securing said half-circle plate against said first housing when cam device and mating element are in either the engaged or disengaged position.

Claim 5

A construction fastening device according to claim 2, wherein said plate, axle, flange, gasket and first housing are made of non-magnetic materials.

Claim 6

A construction fastening device according to claim 3, wherein said plate, axle, flange and housing are made of injection-molded glass impregnated nylon.

Claim 7

A construction fastening device according to claim 3, wherein said rotating means is a positioner device, comprising: (a) a position marker; (b) a magnet; (c) a rotatable ring upon which said position marker and magnet are affixed; (d) means for turning said ring about an axial position; (e) a second housing in which said ring, position marker and magnet are contained, and which has an opening into which said turning means may be applied to turn the ring about a perpendicular central axis.

Claim 8

A construction fastening device according to claim 5, wherein said securing means comprises: (a) a plurality of nubs located on the inside face of one of said broad sides of said first housing; (b) a plurality of indents located on one side of said half-circle plate corresponding to said nubs, whereby said nubs fit snuggle, into said indents when said cam device is in either a fully open (disengaged from mating locking element) or fully closed (engaged to mating locking element) position, and whereby said indents are lifted out and away from said nubs so that cam device may be rotated to its opposite position by placing said positioner device in the proximity of said first housing on the side opposite said nubs and indents and allowing the operation of a magnetic force of said magnet upon said magnetic slug so that said half-circle plate is drawn toward the magnetic force.

Claim 9

A construction fastening device according to claim 6, further comprising a first building panel in which said first housing is contained.

Claim 10

A construction fastening device according to claim 6, further comprising a first building structural element in which said first housing is contained.

Claim 11

A construction fastening device according to claim 7, further comprising a second building structural element in which said mating locking element is contained.

Claim 12

A construction fastening device according to claim 8, further comprising a second building panel in which said mating locking element is contained.

Claim 13

A construction fastening device according to claims or 10, wherein said first and second building panels are composed of non-magnetic material.

Claim 14

A construction fastening device according to claims or 9, wherein said first and second building structural elements are composed of non-magnetic material.

Claim 15

A construction fastening device according to claims or 9, wherein said first and second building structural elements are composed of pultruded high strength fiberglass.
