Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
A closure device for a skylight opening having a surrounding rim comprising: a sliding roof including a roof panel, a rectangular girder frame supporting the panel, and sealing strip; guiding means positioned on the rim for guiding the sliding roof for movement between open and closed positions; a metal profile positioned on said rim and having an outwardly projecting rim flange positioned on an upwardly extending portion of said profile; and wherein said girder frame includes: a girder forming at least one side of said girder frame, said girder having a vertical web with an outwardly projecting upper flange forming an inverted track for said guide means, an opposed lower flange spaced apart from said upper flange, the space between said upper and lower flanges forming a channel embracing said guide means, and an inwardly projecting flange positioned below said rim flange in the closed position to form a labyrinth seal between said sliding roof and said rim; and wherein said sealing strip comprises: a cantilever, resilient strip extending adjacent the inward side of said vertical web, one edge of said resilient strip being attached to said vertical web and the other edge engaging said rim flange in the closed position.
Claim 2
Dependent Claim
201 words
A closure device for a skylight opening having a surrounding rim comprising: a sliding roof including a roof panel, a rectangular girder frame supporting the panel, and sealing strip; guiding means positioned on the rim for guiding the sliding roof for movement between open and closed positions; a metal profile positioned on said rim and having an outwardly projecting rim flange positioned on an upwardly extending portion of said profile; and wherein said girder frame includes: a girder forming at least one side of said girder frame, said girder having a vertical web with an outwardly projecting upper flange forming an inverted track for said guide means, an opposed lower flange spaced apart from said upper flange, the space between said upper and lower flanges forming a channel embracing said guide means, and an inwardly projecting flange positioned below said rim flange in the closed position to form a labyrinth seal between said sliding roof and said rim; and wherein said sealing strip comprises: a cantilever, resilient strip extending adjacent the inward side of said vertical web, one edge of said resilient strip being attached to said vertical web and the other edge engaging said rim flange in the closed position.
Claim 3
Dependent Claim
96 words
A closure device as claimed in claim 1 wherein the labyrinth seal is provided along one of the sides extending transversely of the moving direction of the sliding roof, and further comprising on the girder frame along said one side a pivoted angular bar which is operable between a lowered position in which the angular bar projects under the projecting flange on the rim in the closed position of the sliding roof, and a raised position in which the angular bar clears the rim at the movements of the sliding roof between open and closed position.
Claim 4
Dependent Claim
72 words
A closure device as claimed in claim 1 further comprising along one of the sides extending transversely of the moving direction of the sliding roof a blade spring mounted to the lower side of the frame and sealingly engaging the rim in the closed position of the sliding roof, the spring being formed to slide to and from such engagement at the movement of the sliding roof between open and closed posItion.
Claim 5
Dependent Claim
58 words
A closure device as claimed in claim 1 further comprising on the inner side of each of the girder frame and the rim a covering heat insulating panel, the panels being mutually spaced, and further comprising in the space between the panels a flexible hose seal which is expandible by fluid to fill the space between the panels.
Claim 6
Dependent Claim
60 words
A closure device as claimed in claim 1 further comprising on the inner side of the girder frame and the rim a covering heat insulating panel, one of these panels being displaceable between a first position in which said one panel engages the other panel, and a second position in which said one panel is retracted from said other panel.
