Abstract
Abstract An expansion joint cover for effectively sealing the joint between two shiftable roof sections while permitting the natural expansion and contraction of the latter which employs a cover plate resiliently mounted on one of a pair of support members on opposite sides of the joint with a bolt and coil spring therearound so as to bias the cover into a sealing position on both supports, the bolt and spring being positioned proximal to the joint between the two sections and providing a balanced sealing action on the respective supports.

Total Claims: 16
Claim 1
Independent Claim
229 words
A roof joint cover assembly for structural sections cooperable to present a roof for a building and including a pair of spaced sections defining a joint therebetween, said assembly comprising: a first component adapted to be secured tO one of the structural sections adjacent the joint defined thereby and including a first part configured to generally complementally engage a surface portion of said one structural section, and a second part joined to said first part and extending away from the latter in a direction toward the joint; a second component adapted to be secured to the other structural section of the pair thereof and having a segment extending away therefrom, said segment being provided with a terminal edge remote from the other structural section terminating in substantial alignment with said second part of the first component; a cover plate overlying said parts of the first component in spaced relationship therefrom and engaging the terminal edge of said segment of the second component and the first part of said first component; connector means on the cover plate and extending through the second part of said first component for pivoting movement relative thereto; and resilient means on the connector and engaging said second part of the first components for biasing the cover plate into tight engagement with said first part of the first component and the segment of said second component.
Claim 2
Dependent Claim

A roof joint cover assembly for structural sections cooperable to present a roof for a building and including a pair of spaced sections defining a joint therebetween, said assembly comprising: a first component adapted to be secured tO one of the structural sections adjacent the joint defined thereby and including a first part configured to generally complementally engage a surface portion of said one structural section, and a second part joined to said first part and extending away from the latter in a direction toward the joint; a second component adapted to be secured to the other structural section of the pair thereof and having a segment extending away therefrom, said segment being provided with a terminal edge remote from the other structural section terminating in substantial alignment with said second part of the first component; a cover plate overlying said parts of the first component in spaced relationship therefrom and engaging the terminal edge of said segment of the second component and the first part of said first component; connector means on the cover plate and extending through the second part of said first component for pivoting movement relative thereto; and resilient means on the connector and engaging said second part of the first components for biasing the cover plate into tight engagement with said first part of the first component and the segment of said second component.
Claim 3
Dependent Claim
47 words
The invention of claim 1, wherein said cover plate is channel-like in configuration with the skirts on opposite sides thereof extending generally downwardly toward said roof in overlying relationship with corresponding portions of the segment of said second component and the first part of said first component.
Claim 4
Dependent Claim
57 words
The invention of claim 1, wherein said first and second components are of generally inverted T-shape configuration and are each provided with an integral flashing member on their respective extremities remote from said joint, said flashing members extending generally downwardly toward said roof and outwardly from said joint along corresponding structural sections in spaced overlying relationship therewith.
Claim 5
Dependent Claim
51 words
The invention of claim 1, wherein said second part of the first component is provided with a surface remote from said one structural section in substantial parallelism with the latter and with said outer edge of the segment of said second component, said surface being adapted to engage said cover plate.
Claim 6
Dependent Claim
52 words
The invention of claim 4, wherein said surface of the second part of the first component and said terminal edge of the segment of said second component are each provided with a compressible sealing member extending along their respective lengths and disposed to engage said cover plate and effect a seal therebetween.
Claim 7
Dependent Claim
57 words
The invention of claim 1, wherein said connector means includes a bolt having a head thereon and a nut threaded on said bolt below said second part of said first component, said resilient means on the connector means including a coil spring surrounding said bolt and engaging said nut and said second part of the first component.
Claim 8
Dependent Claim
39 words
The invention of claim 1, wherein both of said components and said cover plate are elongated and extend along the length of the joint, said connector means being provided at spaced intervals along the length of the cover plate.

The invention of claim 1, wherein said first component is generally L-shaped and is provided with a finger unit extending generally outwardly from said first part of said first component toward said joint and downwardly toward said second part of said first component, said finger unit and said first part defining a channel within said first component.
Claim 10
Dependent Claim
53 words
The invention of claim 8, wherein said second component is generally of inverted T-shaped configuration and provided with an integral flashing member on an extremity remote from said joint, said flashing member extending generally downwardly toward said roof and outwardly from said joint along its corresponding structural section in spaced overlying relationship therewith.
Claim 11
Dependent Claim
107 words
The invention of claim 9, wherein said cover plate is generally of Z-shape configuration with a first skirt on one of the extremities of said Plate extending generally downwardly toward said roof in overlying relationship with a portion of the segment of said second component and with a second skirt on another extremity of said plate extending generally upwardly into said channel between said finger unit and the first part of said first component with the terminal end of said second skirt engaging the inner surface of said first component at the point of juncture of said finger unit with the first part of said first component.
Claim 12
Dependent Claim
93 words
The invention of claim 10, wherein said second skirt is provided with a bead on the terminal end thereof adapted to be complementally received within a corresponding bead-shaped slot provided within the inner surface of said first component at the point of juncture of said finger unit with the first part of said first component, the distance across the opening of said slot being smaller than the cross-sectional diameter of said bead in order to secure the terminal end of said second skirt to said first component while permitting pivotal movement relative thereto.
Claim 13
Dependent Claim

The invention of claim 10, wherein said first part of said first component is provided with compressible sealing means extending along the length thereof and adapted to engage said one structural section and effect a seal between the latter and said first component
Claim 14
Dependent Claim
39 words
The invention of claim 12, wherein said terminal edge of the segment of said second component is provided with compressible sealing means extending along the length thereof and disposed to engage said cover plate and effect a seal therebetween.
Claim 15
Dependent Claim
57 words
The invention of claim 10, wherein said connector means includes a bolt having a head thereon and a nut threaded on said bolt below said second part of said first component, said resilient means on the connector means includes a coil spring surrounding said bolt and engaging said nut and said second part of the first component.
Claim 16
Dependent Claim
39 words
The invention of claim 10, wherein both of said components and said cover plate are elongated and extend along the length of the joint, said connector means being provided at spaced intervals along the length of the cover plate.
