Description

The invention relates to a glass roof, in particular a conservatory, with a shading element which can be pulled over the glass surface, wherein the shading element is arranged in the non-extended state down in the region of the eaves in a box or hollow profile and the shading element can be pulled up over the glass surface ,

Shades for the top of a glass roof, in particular a winter garden, are known with a cloth ( DE 38 41 139 A . FR-A-2 577 606 ), where the cloth shaft sits at the highest point of the glass roof, so that the cloth is pulled down over the sloping glass surface. In order to accommodate the fabric shaft, a cloth shaft box is required in the top glass roof area, which is visually unattractive and takes away a part of the upper glass surface or unnecessarily shaded.

From the EP-A-0 670 109 is a shading according to the preamble of claim 1 is known.

From the DE 299 07 300 U1 is a drainage channel for conservatories known in which the inclusion of rolled or folded sun protection elements has been integrated.

From the post-published EP 0 994 221 A2 is a shading for the outside of a glass roof, in particular a conservatory with a roll on a roll cloth which is pulled over the glass surface, wherein the fabric shaft is arranged below the eaves in a box or hollow profile and the cloth up over the glass surface can be pulled, known, in which the fabric shaft by means of a, attached to the front edge of the cloth drop rail in guide rails, which simultaneously fulfill the function of the support of the glass surface or the function of the glass clip strip, can be pulled up over the glass surface.

The object of the invention is to improve a glass roof with a shading element of the type mentioned above so that the shading receiving box is not visible, and also the glass surfaces are not reduced or shaded, and to simplify the construction of the glass roof and the shading device, wherein the shading device has a long service life.

This object is achieved by a glass roof, in particular a conservatory, according to claim 1.

As a result, the shading element is arranged in the non-extended state, in particular the shaft of the shutter in a region of the glass roof, which provides sufficient space for the shading without reducing the glass surface of the roof. This leads to a visually particularly beautiful and elegant system. It can be used optimally in winter garden roof systems in particular. Always the required profiles of relatively small external dimensions.

A very long life is achieved in that the shading element slats or a roller shutter has.

A structurally particularly simple and effective design with a long service life is created by the fact that the shading element can be pulled upwards over the glass surface by means of a drop-down strip fastened to the front edge of the shading element in guide rails which at the same time fulfill the function of the carriers or the function of the glass clip strip ,

It is particularly advantageous if the shading element / box surrounds the rain gutter when the box / hollow profile is not extended. Here, the shading element by pulling elements in particular by ropes can be pulled upwards, which is fixed in the side of the shading element on a profile with two-sided roles especially on a carriage and the profile or the carriage is pulled by the tension elements / cables.

It is preferably proposed that the rollers run in rafter profiles arranged laterally of the shading element.

Furthermore, it is advantageous if the other end of the tension elements is fixed in each case to a force storage device, in particular to springs such as gas pressure springs. In this case, the clamping system, which pulls up the shading element, have a force accumulator, in particular with gas pressure springs. Also can be attached to the Gasdruckfedem ropes whose other ends are fixed to the shading element or, the shading element final profile, Also, it is advantageous if the ropes parallel to the Gasdruckfedemvedaufen and with end pulleys form a pulley.

It is particularly advantageous if the hollow profiles of the rafters in the longitudinal hollow spaces of the hollow profiles are inserted in a form-fitting axial manner for reinforcement.

In the illustrated embodiments are not embodiments of the invention, but to examples that facilitate the understanding of the invention.

The upper surface of a glass roof, in particular a winter garden has inclined rafters 1, which carry the glass sheets 2 therebetween. In the region of the eaves the rafters 1 are connected to each other by at least one profile 3, which forms a gutter in the form of a box 4 or hollow profile.

In box 4 or in the hollow profile, a cloth shaft 5 is mounted, on which the cloth 6 is wound to shade the overlying glass sheet 2. In the cloth shaft 5, a motor is arranged, through which the cloth 6 is wound onto the shaft 5 against the train of a force accumulator 8 described below.

The cloth 6 is attached to the upper horizontal end of a front rail 9, at its two end sides in each case a roller 10 is fixed, which projects laterally beyond the cloth.

Profile 9 and rollers 10 thus form a carriage 11, with which the cloth is pulled up over the glass pane 2 away. Here, the rollers 10 each run in a guide groove 12 of a profile 13, which in addition the glass clip strip 13 and the glass clip strip 13 is thus the edge of the glass pane 2 in the rafters 1 attached.

The rafter 1 has an upper profile 14 and a lower profile 15, which are interconnected by thermal separations 16. Between these two profiles 14 and 15, the glass sheet 2 is located. Above the profile 15 and the side of the profile 14, the glass clip 13 is snap-mounted.

Laterally of the Glasclipprofiils 13, the upper profile 14 forms a rectangular in cross-section longitudinal chamber 17, in which the energy accumulator 8 rests with gas pressure springs 18 and ropes 19.

The carriage 11 or, the dropper profile 9 is connected via cables 19 to the gas pressure springs 18, preferably two or more Gasdruckfedem coaxially connected to each other and form with the cables 19, the clamping system, which is tensioned when the cloth 6 is pulled by a motor down , In this case, the cables 19 run over deflection rollers 20, which are hinged to a block 21 which is located at the upper end of the rafter and to which also one end of a gas pressure spring 18 is attached. The rollers 20 together with the ropes 19 a pulley, within which the gas springs 18 are arranged, the gas springs, the ropes, and the rafters running parallel to each other, the gas springs and the ropes are in the chamber 17 of the rafters. The glass sheets 2 are sealed on both sides in the rafters 1 by rubber seals 2a.

The shading is thus field by field with individual slats or cloth strips between the rafters 1. The towels are on a continuous, in the Rain gutter integrated cloth shaft wound up. The tightening of the curtain is ensured by tensioning systems that are not visible from the outside in the rafters. The ropes 19 of the clamping systems - two each cloth - emerge at the upper ends of the rafters 1 from the profiles and are attached to the dropouts 9.

The clamping systems located in the rafters consist of a variable number of gas pressure springs 18, which are connected to each other as well as with two roller mounts 21. The upper roller mount 21 is fixed in the rafters, the lower counterpart is slidable in the longitudinal direction of the system, is pulled at the free end of the pulley 20 looped over steel pulley 19 (at retracting cloth), the gas springs are compressed, the lower roller support leads in the direction of upper and the pulley system releases rope. The rope end attached to the front profile can also complete the retraction movement of the shade. Due to the linear characteristic of the gas pressure springs, the cloth is always under the same tension.

If a roof system with integrated shading is desired, the rafters are supplied with clipped guide rails for the carriage rollers of the drop profiles. These clips form at the same time the glass clamping strip, If a pure roof system without shading desired, terminal strips 13a are used without guide grooves. The customer has the option of retrofitting the shading system at a later date.

Numerous other technical versions and design variants are possible. So it is conceivable, for example, to place the clamping system (power storage) also in the Glasclipleisten 13. This offers an assembly and maintenance advantage, since the entire system would be easy to replace. Also, the clamping system (power storage) can be arranged in the front rail (trolley) 9, 11 or in a bar / a profile that runs across all fields / glass surfaces horizontally and the strips / carriage 9, 11 all fields / glass surfaces entrains. Also, the drop profiles can be interconnected, so not every field has to be stretched separately. Two clamping elements at the corners of the cloth composite would be sufficient. Furthermore, the tensioning system (power storage) can be arranged in the roof ridge.

In addition to pitched roofs, derelict roofs and the resulting triangular and trapezoidal areas can also be shaded.

The embodiment shown in FIG. 8 has two glass clip profiles 13 which can be detachably fastened by swiveling on both sides of the upper rafter profile 14 in such a way that their upper side is flush with the upper side of the profile 14. The glass clip profiles 13, in turn, have guide grooves 12 LS raceways for carriages 11, which pull the cloth over the glass pane 2.

In the lower rafter hollow profile 15 and in the upper rafter hollow profile 14, a steel profile 22, 23 is axially fitted in each case in the inner cavity, which fit positively in the cavities to reinforce the profiles 14, 15. The steel profile 22 is a box hollow profile and the steel profile 23 is a band profile.

The thermal separation 16 between the two rafter profiles 14, 15 consists of a composite of two angle profiles plastic box profile 24 which is filled with a particular closed-cell plastic foam 26 and outside longitudinal ribs 25 for attachment to the profiles 14, 15 has.

In drawings not shown in the drawings, the shading and thus the shading element is formed according to the invention of a shutter or horizontal slats, which is pulled over the glass surface outside / are.
