Abstract

dormer with a standing skylight whose outwardly upstream parapet the Tilt and cover the broken roof area absorbs and continue characterized in that the roof window with a downwards extended Window section forms an emergency exit, with one of the corresponding French window (2) upstream parapet part (4), with its pivotally mounted, tilted outwards underframe (7) a tread (5) and if necessary supplemented by steps (8).

Description

The The invention relates to a Dachgaupe, in particular a Fledermausgaupe and / or Schleugggaupe, which undergoes an enlargement and so as an emergency exit for expanded Attic is suitable.

To meet fire safety regulations, top floor apartments must have an emergency exit. This must have a size of at least 120 × 90 cm ^{2 in} order to provide the fire brigade personnel with sufficient access options and to serve as a refuge for residents.

What at flats above the window is feasible, puts in the expansion of attics because of the small dimensions Dachgaupen and thus the window a structural problem This is exacerbated by the fact that an increase in the Dachgaupe often for the sake of Monument protection or other town planning reasons the changed view associated with it excretes.

Is known from the DE 87 07 653 U1 a roof garden apartment window. Here, for the purpose of using the roof space for residential purposes, the roof surface is formed by lamellar body, which are erectable and forward, ie away from the window. In this case, the usual design of blinds is used, namely the tiltability of the slats and the pushing together of the slats. As a result, an accessible free usable area in front of the standing window is created. Accepting the replacement of the tiles is precisely by lamellae with the necessary complex construction of the lamellar movement mechanisms including the sealing problem. Inevitably with the lamellar arrangement whose displacement is also provided within the roof flight or parallels thereto.

These solution is an alternative to the known Dachgaupe, which without building permission not is feasible to look at.

Furthermore, from the EP 0212001 A2 a side opening horizontally or in the direction of the roof inclination approximately parallel to the plane of the roof skin boundary opening and retractable cover known. This solution will not expose any exit surface that meets the requirements for an emergency exit.

Further details concerning dormers are in the DE 1804327 B . US 2004/0103597 A1 and US 52 09 030 A described.

task The invention is a technical solution for the field of tension between economic interest in the attic, fire safety To provide provisions and conservation protection views.

Is solved this object with the features of claim 1, advantageous embodiments, Subject of the dependent claims.

According to the invention is at a Dachgaupe with a standing roof window, the outwardly upstream parapet absorbs the inclination and the coverage of the broken roof area and continue provided that the skylight extended with a downwards Window section forms an emergency exit, with one of the corresponding French window upstream parapet part, with its pivotally mounted, tilted outwards underframe a tread releases and if necessary supplemented by steps.

The parapet part takes in an advantageous embodiment in the for the emergency exit erected position opposite a vertical angle of attack (α), the angle of attack a fire ladder comes close or corresponds.

Further remains with tipped base between the French window and the Leading edge of the parapet otherwise continuing the roof passage a clear distance.

When tread So a section of the cornice can be used.

On this way it is possible comply with the fire safety regulations and the original z. B. required by the monument protection view is preserved.

In a preferred embodiment the underframe is designed as a frame. Next is on or in the tread a substantially parallel to Dachtraufe extending tilt axis arranged over the the composite of the underframe and the mounted parapet part can be tilted and tilted, after tilting the now erected underframe for the Emergency exit a parapet forms, at the upper end substantially parallel to the tilt axis a folding axis is arranged over the upstream parapet section can be folded outwards at a defined angle.

These Wegklappbewegung can additionally with coupled a sliding movement of the parapet part be.

To get from one to the other parking position, the base tilts over the tilting axis from one to the other support frame, where when the roof is tilted to the roof, the undercarriage approaches the French window, while when it is tilted outwards it moves away from the French window to raise the parapet for the emergency exit.

there preferably serves at least one leading away from the tilt axis Section of the underframe as a support of the undercarriage on the tread.

The Undercarriage has an or an advantageous embodiment several treads, which stand in upright parapet for the emergency exit in a horizontal position.

of course is it makes sense if the base and / or the parapet part each over Locking devices in the two parking positions.

The intended training of Dachgaupe should be based on the drawings explained become. Show it:

1 Dachgaupe with enlarged window,

2 Dachgaupe with parapet part closed, in the roof view

3 Dachgaupe with parapet part closed in the sectional view and

4 Dachgaupe with unfolded parapet part.

1 shows a bat rooster 1 with an enlarged roof window, leaving a French window 2 arises. This would comply with fire safety regulations. The view does not correspond in any way to our aesthetic taste. That's why, in front of the French window 2 the previous roof 3 essentially optically preserved, but as outwardly tiltable parapet 4 embody. This is shown by the 2 to 4 , once as Dachgaupe with closed parapet part 4 in the roof view and in section and once with unfolded parapet 4 ,

Out 2 it can be seen that through the parapet part 4 the view of the roof 2 preserved in its original form.

Such a parapet part 4 may consist of a frame with battens, the roof tiles are firmly mounted on the roof battens.

In 3 is the superior, in the roof of the roof 3 lying parapet part 4 on a base 7 arranged. Between the French window 2 and the leading edge of the otherwise the roof escape continuing parapet part 4 there remains a free space. This does not change the roof view from the outside, but increases the light entering through the lower window section of the French window 2 ,

The parapet part 4 rests on the base 7 off and the undercarriage 7 is on the tread 5 stored.

In the illustrated embodiment is on or in the tread 5 a substantially parallel to Dachtraufe extending tilt axis 9 arranged over which the composite from the undercarriage 7 and the supported parapet section 4 can be tilted in and out. After tipping the then formed upright frame 7 for the emergency exit a parapet, at the upper end substantially parallel to the tilt axis 9 a folding axis 11 is arranged, over which the upstream parapet part 4 can be folded outwards at a defined angle.

The lower edge of the parapet part 4 is supported in the gutter by a support and / or sliding and / or pivot bearing, so that the parapet part 4 is guided over the gutter when unfolding.

The undercarriage 7 is preferably designed as a frame. Two parallel racks 7 in this frame form ensure optimal storage and management of the parapet part 4 ,

As shown, the underframe 7 over one or more treads 8th which are in the unfolded. Position of the parapet part 4 in a horizontal position.

The undercarriage 7 and / or the parapet part 4 each have locking devices in the two parking positions.

4 shows the Dachgaupe with unfolded parapet part 4 , The parapet part 4 was with the undercarriage 7 tilted outwards to the folding axis 11 unfolded while slidably guided and supported in the gutter. The parapet part 4 points in this erected for emergency exit position against a vertical 6 an angle of attack (α), which comes close to or corresponds to the angle of attack of a fire ladder.

The undercarriage 7 , designed as a frame, has two treads 8th on, which are in the position shown in a horizontal position. As a stepping surface 5 serves a section of the cornice.

In the two parking positions of the undercarriage 7 by tilting over the tilt axis 9 be reached from one to the other support frame, wherein in the tilted roof to the position of the base frame 7 the French window 2 approaching while tilting outward again from the French window 2 removed to erect a parapet for the emergency exit, one serves each of the tilt axis 9 wegführender section of the undercarriage 7 as a support of the undercarriage 7 on the tread 5 ,

With the proposed solution becomes cost effective and universally applicable a roof girder design offered that corresponds to the economic interests in the loft conversion, guarantees compliance with fire safety regulations and monument protection claims enough.
