Abstract
Abstract A window or door construction for a building is shown wherein the frame carrying the glass pane or the window or door wing is not fixedly connected to the building but is "floatingly" disposed in a case. Therefore, if adequate spaces are taken into account, the frame can freely move in the case and expand and contract under thermal influences independently of the building. The invention makes it possible to realize window or door constructions of a plastic profile material which, if necessary, also withstand arctic temperatures without their weld joints cracking.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A window or door construction for a building, including a frame of a plastic profile material for receiving a single or multiple glass pane or for holding a window or door wing pivotally and/or tiltably mounted thereon, said construction comprising said frame having at its circumferential side a channel-like recess whose opposite walls preferably extend substantially parallel to each other; and said frame being disposed in a case whose inside dimensions are a few centimeters greater than the corresponding external dimensions of said frame; and said case having at the inner side of all of its legs a respective retaining rail which projects inwards and engages said channel-like recess in said frame profile and whose height is matched to the depth of said channel-like recess such that the distance between opposite retaining rails is respectively a few centimeters greater than the distance of the bottoms of two opposite channel-like recesses; said frame profile and the parts in contact therewith being sealed with respect to each other by elastic seals of profiled material, sealing strips which are adjacent said retaining rail being fastened to a free end of the frame profile.
Claim 2
Dependent Claim
190 words
A window or door construction for a building, including a frame of a plastic profile material for receiving a single or multiple glass pane or for holding a window or door wing pivotally and/or tiltably mounted thereon, said construction comprising said frame having at its circumferential side a channel-like recess whose opposite walls preferably extend substantially parallel to each other; and said frame being disposed in a case whose inside dimensions are a few centimeters greater than the corresponding external dimensions of said frame; and said case having at the inner side of all of its legs a respective retaining rail which projects inwards and engages said channel-like recess in said frame profile and whose height is matched to the depth of said channel-like recess such that the distance between opposite retaining rails is respectively a few centimeters greater than the distance of the bottoms of two opposite channel-like recesses; said frame profile and the parts in contact therewith being sealed with respect to each other by elastic seals of profiled material, sealing strips which are adjacent said retaining rail being fastened to a free end of the frame profile.
Claim 3
Dependent Claim
44 words
The construction according to claim 1, wherein said case has at least towards one side of said retaining rail a cover strip which extends parallel thereto and forms a channel for receiving a leg portion of said frame profile together with said retaining rail.
Claim 4
Dependent Claim
19 words
The construction according to claim 2, wherein said cover strip and said case are designed as a constructional unit.
Claim 5
Dependent Claim
21 words
The construction according to claim 2 or 3, wherein said retaining rail and said case are designed as a constructional unit.
Claim 6
Dependent Claim
33 words
The construction according to claim 1, wherein sealing strips which are adjacent the neighboring walls of said channel-like recess of said frame profile are fastened to the interior end of said retaining rail.
Claim 7
Dependent Claim
25 words
The construction according to claim 2, wherein as sealing strip which is adjacent said frame profile is at least fastened to the exterior cover strip.
Claim 8
Dependent Claim
20 words
The construction according to claim 2, wherein said retaining rail is provided at a higher level than said cover strip.
