DE202011101192U1 - Folding mechanism for mounting the house wall side of light shaft covers - Google Patents

Abstract

Folding mechanism for attaching light shaft covers to building walls, which consists of two hollow profile rails (1) with an insertion opening and a double-edged strip (2) drawn into it and in which one hollow profile rail (1) is attached to the building wall and to the light shaft cover.

Description

The invention relates to a folding mechanism for flexible attachment of surfaces, in particular oblique covers or flat-fitting covers made of plastic or glass, as they come as a rain protection on basement light wells used.

Previously known fastening methods in this area are sometimes not flexible, since the covers are fixed with screws on the building wall, or on the inset in the light shaft grid.

Known movable mounting types are very massive and expensive to manufacture, provided that they are made of metal components. Other systems use only plastics, which are lighter, but do not permanently withstand a load caused by opening and closing the manhole cover, as material fatigue and consequent breakage of the joint can quickly occur. In DE 20 2010 0047 33 U1 is presented a hollow profile with sliding mechanism, but rather goes in the direction of a curtain attachment, is not hinged and is not suitable for the attachment of surfaces on vertical walls.

In addition, the wall connection in such light shaft covers and wall connecting elements is always a Eintrittsfuge for outflowing precipitation.

Object of this invention is to provide a folding mechanism for attaching surfaces, especially slanted covers, or other covers for basement light wells, which is permanently flexible, easy to assemble and easy to clean for cleaning purposes, which looks visually light and attractive, its components weatherproof and whose wearing parts are easily and inexpensively exchangeable, and which effectively protects the wall connection against penetrating precipitation.

According to the invention this object is achieved with the main claim. Further advantageous embodiment are defined in claims 2 to 6.

The folding mechanism according to the invention consists of two hollow-section tubes made of aluminum, whose shape is designed in approximately P-shaped, wherein the profiles are not completely closed on one side, but offer an opening for introducing a Kederbandes.

The attachment of the folding mechanism is such that a rail is fastened to the building wall by screw or adhesive connection, in such a way that the opening of the rail facing down. In this case, the gap between the building wall and rail can be sealed with a sealant.

The second rail is also secured by an adhesive or screw on the movable surface to be stored of any material and with any inclination, wherein the opening of the rail facing the edge of the surface to be stored.

Another component of the attachment mechanism is an elastic double-edged ribbon. The two Kederwülste have so large a diameter that they can easily move into the rails, but can not slip out through the opening of the rails. The piping cord is thereby anchored safely and yet flexible in the rail, without additional fasteners are needed.

The two Kederwülste the Doppelkederbandes are so far apart that the flat bridge between them is sufficient to fold the cover up without the two rails can block each other.

The double-edged strip can, for example, consist of material also used in the camping area and is therefore very weather-resistant. When worn, it can be easily and inexpensively replaced.

The invention will be explained in more detail by way of example with reference to the drawings. Show it:

1 an overall view of the folding mechanism according to the invention,

2 a cross section through the folding mechanism according to the invention,

3 the cross section of a possible hollow profile rail ( 1 )

4 an advantageously executed double feathered strip ( 2 ).

1 shows a possible embodiment of the folding mechanism according to the invention for attaching covers, in particular light shaft covers, to building walls. The mechanism according to the invention is composed of two hollow profiled rails ( 1 ) and a double elastic band ( 2 ).

2 shows schematically the interlocking of the individual components. The two preferably equal length hollow profile rails ( 1 ) are in the desired mounting height on the building wall ( 4 ) or on the building wall ( 4 ) surface to be fastened ( 3 ) appropriate. The building-side hollow profile rail is mounted so that the open side faces down. This has the advantage that at this point no drainage wetness can penetrate. The on the surface ( 3 ) attached hollow profile is placed so that the open side at the edge of the surface to be fastened ( 3 ) lies. The connecting double-feathered band ( 2 ) can be easily pulled into both rails and removed for cleaning purposes. Should there be a wear of the double Cedar strip ( 2 ), this can be exchanged at very low cost.

3 shows a possible cross section of the hollow profile rail ( 1 ), which consists of stable, weather-resistant material, preferably of aluminum. The hollow profile rail ( 1 ) is formed so that it has a flat rail web ( 1b ), with which they plan on the building wall ( 4 ) or the surface to be fastened ( 3 ) rests and can be fixed there. On this bridge is the actual hollow profile in the form of a piping rail ( 1a ), which for receiving the Kederwulstes ( 2a ) serves.

4 shows the double feathered ribbon ( 2 ), which in both hollow profile rails ( 1 ) and is made of an elastic, weather-resistant material. The Kedersteg ( 2 B ) between the two Kederwülsten is so wide that the two hollow profile rails ( 1 ) when folding up the surface ( 3 ) do not block each other.
