Abstract

A window of a residential roof with a window wing (a folding skylight shutter) which is supportably relieved of weight by an accumulator and which swings open about an upper axis of the blind window frame, the wing after decoupling additionally being able to be turned over about an axis lying substantially in the longitudinal center line, the axial pins of the last-mentioned axis being seated on carrier arms which are articulated in the vicinity of the upper transverse leg of the blind window frame and extend in the direction of the longitudinal legs of the blind window frame. The longitudinal legs of the window wing and the blind frame lie flushly aligned one above the other and the carrier arms including the accumulators which load the arms are arranged in the open angle or corner between the wing and the blind window frame, whereby the free ends of the carrier arms in the open position of the window wing are movable out to a distance with respect to the blind window frame, which distance corresponds approximately to half the length of the longitudinal leg of the wing.

Claims

1. A roof window of a residential roof comprising

a blind window frame adapted to be secured to a roof and defining an upper axis, said window frame having first longitudinal legs and a first upper and a first lower transverse leg connected together,

carrier arms being articulated to said blind window frame at said upper axis in a vicinity of said upper transverse leg of said blind window frame and extending in the direction of said first longitudinal legs of said blind window frame,

said blind window frame and said carrier arms constituting members,

a window wing including second longitudinal legs and a second upper and a second lower transverse leg connected together, said window wing being pivotally mounted, about a central axis lying substantially in a longitudinal center line thereof, to said

at least one means for decoupleably connecting said window wing at at least one decoupleable connection point to one of said members such that said window wing is swingable open about said upper axis of said blind window frame defining an open angle between said window wing and said blind window frame, and such that only after decoupling said means said window wing is swingable relative to said carrier arms about said central axis and said second lower transverse leg of said window wing is then tiltable into said open angle above said blind window frame and said window wing is free to be turned upside down,

axial pins disposed at said central axis being seated on said carrier arms and pivotally connecting said window wing to said carrier arms,

said longitudinal legs of said window wing and said blind window frame lie flushly aligned one above the other,

at least one accumulator means for loading said carrier arms and operatively relieving said window wing of load,

said carrier arms and said at least one accumulator means being disposed in the open angle between said window wing and said blind window frame,

said carrier arms defining free ends, respectively, the free ends in an open position of said window wing being swingable out to a distance with respect to said blind window frame, which distance corresponds approximately to half the length of one of said second longitudinal legs of said window wing.

2. The roof window as set forth in claim 1, wherein

said second longitudinal legs of said window wing define rearwardly opening chambers,

said carrier arms are disposed in said chambers of said second longitudinal legs of said window wing.

3. The roof window as set forth in claim 1, wherein

said at least one accumulator means includes a compression spring,

said carrier arms are U-shaped opening downwardly,

said at least one accumulator means pivots in said carrier arms, respectively.

4. The roof window as set forth in claim 1, wherein

said second upper transverse leg in part defines a rearwardly opening chamber,

means comprising detachable coupling bolts are arranged in said chamber for forming a rigid unit between said carrier arms and said window wing constituting said at least one means and said at least one decoupleable connection point.

5. The roof window as set forth in claim 1, wherein

said first upper transverse leg defines a head side,

additional axial pins pivotally connect said carrier arms to said blind window frame at said upper axis for exposure opening movement of said window wing,

said additional axial pins lie in front of said head side of said first upper transverse leg of said blind window frame.

6. The roof window as set forth in claim 1, wherein

said carrier arms are articulated to said blind window frame at respective articulation points which lie in the range of said open angle between said window wing and said blind window frame.

7. The roof window as set forth in claim 6, wherein

said window wing has an end adjacent the vertex of the angle formed by said articulation points,

said at least one means for decoupleably fixing said end of said window wing to said blind window frame constituting said at least one decoupleable connection point.

8. The roof window as set forth in claim 7, wherein

said blind window frame has an angle formed with an opening,

said at least one means includes withdrawable rod means for decoupling said window wing from said blind window frame at said at least one decoupleable connection point whereby said window wing is swingable about said central axis relative to said carrier arms, said rod means has a rearward end decoupleably inserted in said opening of said angle of said blind window frame yet such that said window wing is pivotal relative to said blind window frame with the rearward end inserted in said opening of said angle.

9. The roof window as set forth in claim 8, further comprising

said at least one means further includes exposure bars pivotally connected to said window wing and releaseably engageable on said blind window frame constituting another of said at least one decoupleable connection point.

said rod means are coupled with said exposure bars such that a movement of said exposure bars which is directed opposite to an opening swinging of said exposure bars decouples said rod means from said angle, said opening swinging of said exposure bars decoupling the latter from said blind window frame.

10. The roof window as set forth in claim 9, wherein

said rod means are concealed in the profile of said window wing.

11. The roof window as set forth in claim 1, wherein

said at least one accumulator means is formed as a tension spring which is disposed in said carrier arms, respectively, operatively engaging said blind window frame and said window wing.

12. The roof window as set forth in claim 11 further comprising

said carrier arms are articulated to said blind window frame at respectively articulation points which lie in the range of said open angle between said window wing and said blind window frame,

bearing blocks secured to said blind window frame adjacent said first upper transverse leg,

said articulation points are on said bearing blocks, said carrier arms articulated to said bearing blocks, respectively,

cable lines connect one of the ends of said tension springs with said bearing blocks, respectively at other points on said bearing blocks such that said cable lines pass above said articulation points.

13. The roof window as set forth in claim 1, wherein

said carrier arms are each formed in two parts, said two parts are pivotally connected together in a rearward portion of said carrier arms, whereby the latter are able to be bent in said rearward portion.

14. The roof window as set forth in claim 1, wherein

said at least one accumulator means constitutes two accumulators at least pivotally connected to said carrier arms, respectively, and to said blind window frame.
