Roofing laminate fastener assembly

Claim 2

A fastener assembly comprising: a flanged cap nut; a keeper nut, and a toggle bolt, wherein said toggle bolt comprises a threaded stem component, and a toggle nut component threaded thereon; and wherein said cap nut is provided with a longitudinal bore hole adapted to receive and threadably connect with said stem component, said cap nut also being provided with a shaped recess in the top thereof having a shape complementary to, and adapted to receive said keeper nut such that when said keeper nut is inserted therein, rotation of said keeper nut independent of said cap nut is prevented; and wherein further, the lower end of said keeper nut is provided with means adapted to engage the top end of said toggle stem and to prevent the rotation thereof independent of said keeper nut, while the top end of said keeper nut is fitted with torquing means; and wherein still further the lower end of said toggle stem component is modified so that the toggle nut threaded thereon cannot be threaded past the lower end of said toggle stem component.

Claim 3

A roof structure in which insulation is fastened onto a roof deck by means of a fastener assembly according to claim 1.

Claim 4

A fastener assembly according to claim 1 wherein the engagement means and torquing means, respectively, comprise recesses having hexagonally shaped horizontal cross-sections, and the top end of said toggle stem has a hexagonal shape complementary, to and designed to fit into the recess of said engagement means.

Claim 5

A fastener assembly according to claim 3 in which, however, the recess of the engagement means is located in the top end of said toggle stem, while the lower end of the keeper nut is fitted with a hexagonal shape thereon complementary to the shape of a recess in the top end of said toggle stem, and designed to fit therein.

Claim 6

A fastener assembly according to claim 1 in which the threadable connection between said threaded stem component and the cap nut is provided by means of threads located in at least a portion of said bore hole, in contact with the threads of said stem component.

Claim 7

A fastener assembly according to claim 5 in which said cap nut is fabricated from plastic.

Claim 8

A fastener assembly according to claim 6 in which the threads located in said bore hole are provided by a threaded retainer nut incorporated in said cap nut.

Claim 9

A fastener assembly according to claim 1 in which the engagement means comprises the interconnection between a blade component and complimentary slot component, said blade component being attached to the top end of the toggle stem, and the complimentary slot component being recessed in the lower end of said keeper nut, or wherein the blade component is attached to the lower end of the keeper nut, and the complimentary slot component is recessed in the top end of the toggle stem.

Claim 10

A fastener assembly according to claim 1 in which said torquing means comprises a slot recessed in the top of said keeper nut adapted to receive a complementary blade member.

Claim 11

A fastener assembly according to claim 1 in which said keeper nut either has a hexagonal or a square horizontal cross-section.

Claim 12

A roof structure in which insulation is fastened onto a roof deck by means of a fastener assembly comprising: a plastic, flange cap nut; a plastic keeper nut, and a toggle bolt, wherein said toggle bolt comprises a threaded stem component and a toggle nut component threaded thereon; and wherein said cap nut is threadably connected to said stem component, and is also provided with a shaped recess in the top thereof, complimentary to, and adapted to receive said keeper nut such that when said keeper nut is inserted therein, rotation of said keeper nut independent of said cap nut is prevented; and wherein further, the lower end of said keeper nut is provided with engagement means adapted to engage the top end of said toggle stem, and to prevent the rotation thereof, while the top end of said keeper nut is fitted with torquing means; and wherein still further, said engagement means comprises a recess and a complimentary shaped member adapted to fit into said latter recess, wherein said latter recess is located in the top end of said toggle stem, while said shaped member is located on the lower end of said keeper nut, or where said latter recess is located in the lower end of said keeper nut, while said shaped member is located on the top end of said toggle stem; and said torquing means comprises a recess, the last two mentioned recesses having hexagonally shaped, horizontal cross-sections; and wherein even further, the lower end of toggle stem component is modified so that the toggle nut threaded thereon cannot be unthreaded past the lower end of said toggle stem component.

Claim 13

A roof structure in which insulation is fastened onto a roof deck by means of a fastener assembly comprising: a plastic, flange cap nut; a plastic keeper nut, and a toggle bolt, wherein said toggle bolt comprises a threaded stem component and a toggle nut component threaded thereon; and wherein said cap nut is threadably connected to said stem component, and is also provided with a shaped recess in the top thereof, complimentary to, and adapted to receive said keeper nut such that when said keeper nut is inserted therein, rotation of said keeper nut independent of said cap nut is prevented; and wherein further, the lower end of said keeper nut is provided with engagement means adapted to engage the top end of said toggle stem, and to prevent the rotation thereof, while the top end of said keeper nut is fitted with torquing means; and wherein still further, said engagement means comprises a recess and a complimentary shaped member adapted to fit into said latter recess, wherein said latter recess is located in the top end of said toggle stem, while said shaped member is located on the lower end of said keeper nut, or where said latter recess is located in the lower end of said keeper nut, while said shaped member is located on the top end of said toggle stem; and said torquing means comprises a recess, the last two mentioned recesses having hexagonally shaped, horizontal cross-sections; and wherein even further, the lower end of toggle stem component is modified so that the toggle nut threaded thereon cannot be unthreaded past the lower end of said toggle stem component.
