Abstract

Abstract A roof window includes support beams forming a pyramidal frame structure having an upper top roof and individually movable parallel trapezium-shaped roof or window sections. Each section can be moved between an open and a closed position, an upper guide extending between the base of a side of the pyramid and the top roof and a lower guide projecting outwardly from the said base being provided so as to cooperate with the upper and bottom portions, respectively, of the section. The guides form an angle with each other so that the section performs a combined displacing and swinging movement between its open and closed positions. Seals are provided between the sections and the frame structure. The lower guide is mounted or capable of being mounted on the roof of a building structure supporting the frame structure. The drive for the section may include a wire, a chain or the like extending along the upper guide and connected with the upper portion of the sections and passing over end wheels arranged at the base of the frame structure or in the top roof. At least one of the wheels and preferably the one in the top roof is actuated by a drive motor. The seal includes sealing strips which extend along the side edges of the sections and cooperate with corresponding strips jutting from adjacent sections, said strips being of such configuration that, when the sections are in closed position, they present both an upper and a lower contact line with an insulating space therebetween. In the top roof is arranged a ventilation line provided with a fan which prevents misting or condensation in the region beneath the top roof when the sections are in closed position.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 162 words
A roof closure comprising support beams forming a pyramidal frame structure having upwardly inclined sides, a plurality of trapezium-shaped closure members each adapted to lie parallel on and close one side of said frame structure, upper guide means extending between the base and summit of at least one side of the frame structure to guide an upper portion of a said closure member in a direction parallel to said at least one side, lower guide means projecting outwardly from said base for guiding a lower portion of said at least one closure member in a direction at an oblique angle to the first-named direction, and drive means for raising and lowering said at least one section thereby respectively to close and open said at least one side of the frame structure with said upper portion of said at least one closure member moving along said upper guide means and said lower portion of said closure member moving along said lower guide means.
Claim 2
Dependent Claim 162 words
A roof closure comprising support beams forming a pyramidal frame structure having upwardly inclined sides, a plurality of trapezium-shaped closure members each adapted to lie parallel on and close one side of said frame structure, upper guide means extending between the base and summit of at least one side of the frame structure to guide an upper portion of a said closure member in a direction parallel to said at least one side, lower guide means projecting outwardly from said base for guiding a lower portion of said at least one closure member in a direction at an oblique angle to the first-named direction, and drive means for raising and lowering said at least one section thereby respectively to close and open said at least one side of the frame structure with said upper portion of said at least one closure member moving along said upper guide means and said lower portion of said closure member moving along said lower guide means.
Claim 3
Dependent Claim 49 words
A roof closure as claimed in claim 1, and a shaft on said lower portion of said at least one closure member and movable along said lower guide means to provide a pivot for swinging movement of said at least one closure member relative to said lower guide means.
Claim 4
Dependent Claim 21 words
A roof closure as claimed in claim 2, and antifriction means on said shaft engageable with said said lower guide means.
Claim 5
Dependent Claim 26 words
A roof closure as claimed in claim 1, said lower guide means being mounted on the roof of a building structure that supports said frame structure.
Claim 6
Dependent Claim 21 words
A roof closure as claimed in claim 1, said drive means comprising an endless flexible member parallel to said first-named direction.
Claim 7
Dependent Claim 34 words
A roof closure as claimed in claim 1, said drive means comprising a rotatable screw that extends along said upper guide means and that has screw-threaded engagement with said at least one closure member.
Claim 8
Dependent Claim 34 words
A roof closure as claimed in claim 1, said drive means comprising a chain disposed parallel to said lower guide means and connected with said lower portion of said at least one closure member.
Claim 9
Dependent Claim 63 words
A roof closure as claimed in claim 1, and sealing strips that extend along the side edges of said at least one closure member and that engage sealing strips projecting from adjacent said closure members, said sealing strips in the closed position of their respective closure members having upper and lower lines of contact with each other that define an insulating space therebetween.
Claim 10
Dependent Claim 40 words
A roof closure as claimed in claim 1, said upper guide means projecting in under a lower edge of an upper portion of a roof of a building thereby to seal said at least one closure member against said roof.
Claim 11
Dependent Claim 25 words
A roof closure as claimed in claim 1, said frame structure, guide means and closure members being in unitary assembly for installation over existing buildings.
