DE19623917A1 - Glass gable blind used in buildings for protection against sun, radiation, light and heat - Google Patents

Abstract

The blind is a two-articulated arm blind which is not horizontal or slanted downwards, but vertically retractable in parallel, relative to the glass gable towards the top. The cloth cover does not have the traditional rectangular shape, but a triangular one, pointing upwards. Alternatively, the cloth cover may have a trapezoidal shape, with the smallest parallel side, pointing upwards. The link arms that stretch the blind cloth do not elbowing inwards as in the traditional manner, but outwards.

Description

In the area of shading buildings, terraces, shop windows, street cafes, etc. There is a wide range of ways known to get too much sunbeam prevention and the associated disadvantages.

It is also known that shading within a room (e.g. curtains, Blinds, roller blinds, etc.) reduce the further penetration of the radiation, but hardly their heat production, since the radiation is almost unhindered by the Glass panes have penetrated inside and here the air between the window and the Be shaft element and thus heats the entire interior by means of circulating air thermals.

It is far more effective in retaining radiation and heat Shading from the outside, i.e. before the sun reaches the glass and penetrates inside.

For the glass gables that are becoming increasingly common in new construction areas the possibilities of such shading are severely limited. The bigger the the coherent surface of a glass gable to be shaded, the rarer, more expensive and the previous technical solutions for external shading are becoming more complicated tung.

Who also on vertical guide rails, tension wires, etc. as a necessary Wants to do without the addition of roller shutter and blind concepts, which from the outside disruptive foreign objects cause the image of the large triangular or trapezoidal glass gable design and also hinder the window cleaner, there is nothing in the specialist for him del, which is firstly functional, secondly permanent, thirdly easy to use, fourthly effective from the outside, fifth elegant, sixth technically elegant and seventh protects inexpensively against solar radiation and the associated disadvantages.

The size of this gap in the market becomes clear when you see the large number in new development areas who perceives houses with modern glass gables where there is no possibility of shading there is.

This not only affects those glass gables that, for example (see sketch zen 1 to 3) have glass panel divisions with appropriate framing, in which vertical construction lines are largely missing, but also those where only one Large-sized disc in triangular or trapezoidal shape (completely without surface contact division) is present (see sketches 4 and 5).

To avoid misunderstandings: the object of the invention is not the shading relatively small glass surfaces, which can also be darkened sufficiently from the inside if necessary could, but rather it is about large, triangular and trapezoidal Sunshine areas of several meters in width and height, their heat production in the event of sunshine at best or only approximately by large dimensions, in which Acquisition and expensive air conditioning systems could be compensated for, whereby  the radiation itself would still not have been banned from the room (glare and Health hazard for humans, animals and plants).

Another object of the invention is to exi in as many details as possible to use stable, tried and tested technologies, assemblies and systems in order to Saving development time and costs and risks of a complete undesirable development to minimize lung.

By analyzing and comparing all known external shading options the awning shows itself as the system from which by means of necessary ideas and changes the inventive task of developing a "glass gable shading "is best solved in a trapezoidal or triangular shape.

In the further course of the description, the structure and function of a "normal" Articulated arm awning including the technical system of the articulated arms for the off driving, tensioning and positioning of the cloth provided as known.

The task of the invention requires two basic ideas for the solution finding:

• 1. the conventional (two) articulated arm awning for patio and window seating shading not only for the horizontal or inclined downwards (inclination distributable) to use, but for a movement (almost) vertically insert upwards;
• 2. to modify the "normal" arrangement and kinematics of the articulated arms so that the to be extended, too exciting and in (almost) vertical, upper Cloth to be held in position not only the conventional rectangular shape (extension length × Cloth width) can have, but that the modified system is able to all symmetrical = isosceles triangular and trapezoidal shapes of modern glass gables to be executed, to take their forms and to shade them.

There are two mounting options to consider:

• a) For houses without or with a minimal gable canopy up to approx. 30 cm sensible to arrange the glass gable awning so that the articulated arms to the outside and that Cloth facing the glass gable front, then the articulated arms from inside the room are not visible from (see sketch 6).
• b) In the case of houses with a gable canopy from approx. 30 cm, it makes sense to use the Glass gable awning to be arranged so that the articulated arms between the extendable Cloth and the glass front, so not visible from the outside, are arranged. Here is that Consider the thickness of the interference contour of the articulated arm kinematics,  which, depending on their extension length, has a defined minimum distance between the fabric and glass front is required (see sketch 7).

If you look at an extended "normal" (two) articulated arm awning from above, then one can see an articulated arm arrangement according to sketch 8.

The articulated arms are mounted quite far out; the elbows of the articular artery me point inside. Your lateral distance from each other must be at least as follows be large that the elbow joints are not in the retracted state of the awning touch.

Would you like a glass gable from this "normal" awning with a rectangular cloth? Make an awning with a trapezoidal or triangular fabric, then this is a kinematic arrangement unsuitable because the outer articulated arms over the trapezoidal cloth area (dashed line) and protrude beyond the triangular scarf area (dash-dotted line), which lead to it would that they come up against the eaves from below or if the roof is missing protrude laterally over the roof (see description below) Point 5.).

The following changes are therefore necessary:

• 1. swap the two articulated arms with each other, so that their cubits point the bow joints outwards (see sketch 9),
• 2. Remove the valance from the outer cloth holding element (e.g. profile tube) as it is neither necessary nor sensible with the glass gable awning,
• 3. Ver the articulated arms so far on the square mounting tube towards the center slide, as dictated by the shorter trapezoidal side, and the outer fastening corresponding element for the cloth (e.g. aluminum profile tube) correspondingly short (see sketch 9),
• 4. Move the articulated arms all the way to the middle if a triangular shawl is required and the outer fastening element for the cloth accordingly to a minimum reduce (see sketch 10),
• 5. If necessary, the outer bearing points of both articulated arms at a pivot point unite and thereby completely the outer holding element for the cloth (aluminum profile) make redundant (see sketch 11).

Only points 1 to 5 ensure that the articulated arms are in every position Always remain in the driving position within the outer contour of the cloth. This requirement results not only from optical, safety-related and acceptance reasons, but when installing a glass gable awning within an eaves the cloth as close as possible to the eaves around the glass gable to shade as closely as possible. If here the articulated arms over the cloth contour  would protrude, then they would extend (almost) vertically collide with the roof structure or over if there is no roof overhang extend the roof sideways.

• 6. The wall mounting or mounting on the square mounting tube is by rotating it by at least 90 ° so that the articulated arms do not move outside or diagonally downwards (as with a patio shading), but (almost) Drive vertically upwards and thus guide the cloth directly in front of the glass gable, tension and position.

Both the transverse stiffness of the fabric and the usual articulated arm prestresses are sufficient to ensure the linear movement for the right angle to the cloth as with a normal awning - to guarantee and hold in the desired position.

The tilt adjustment, which is included in a normal awning, can be done with the vertical arrangement of the glass gable awning can be completely saved.

Should there be a terrace and / or a window or a below the glass gable The glass gable awning offers windows that are also to be shaded at the same time the possibility on the correspondingly rigid square mounting tube additionally the articulated arms for another "normal" awning that extends outwards record, so that a special arrangement shown in the sketches 12) and 13) of "two in one" arises in the following essential assemblies the second Awning can be saved:

• a) square fastening tube,
• b) wall mounting,
• c) cloth shaft,
• d) cloth shaft bearing,
• e) manual or electric drive,
• f) wind and sun guard,
• g) tilt adjustment,
• h) Rain and dirt cover.

From sketch 12) it is also clear that in this, through the glass gable awning enabled special awning pairing both fabrics on a shaft up and down be handled, and that you practically the vast majority of technical effort two separate awnings only needed once (partially reinforced accordingly).

This will shade the entire house gable including earth and The upper floor including the terrace in front is particularly inexpensive, technically elegant and "from a single source" (the same cloth pattern, the same technique).
