Abstract

walk Light shaft cover consisting of a plane, translucent Plastic surface (1), preferably made of acrylic glass, consists, at the plastic surface (1) any vent (3) and at the bottom of the plastic surface (1) is reinforced by machined profiles (4) characterized in that the machined profiles (4) are made of metal, and that the machined profiles (4) do not interfere with the plastic surface (1) are connected, and that the machined profiles (4) in the end rest on the light shaft fold (8).

Description

The The invention relates to a walk-in light well cover for covering of light shafts, such as basement light shafts.

conventional Light well covers usually consist of a Metal mesh that works for dirt, insects and moisture does not constitute a barrier.

moreover the metal meshes impair the incidence of light the light shaft.

Previous Solutions for light shaft covers, the one Plastic surface include, are usually additional attached to the conventional shaft grid. These solutions provide no improvement in terms of light incidence.

Light shaft covers in which the entire surface / construction consists of plastic (see Utility Model DE 20 2005 001 011 U1 ), however, often have significant deficiencies in statics and in the tightness against moisture. Among other things, because either no reinforcing bars are provided (see. DE 102004038963 A1 ), or the reinforcement strips do not rest on the light shaft frame.

task this invention is to provide a light well cover, which has a high load capacity, offers better light transmission as a grid-shaped light well cover, the light well largely against the ingress of moisture, dirt and insects protects, without the air circulation through the light shaft to prevent, and the largely weather and UV resistant is.

According to the invention achieves this object with the main claim 1. More before some variants are defined in claims 2 to 8.

The Construction properties ensure a high load capacity the light shaft cover according to the invention and provide low surface area for moisture, in other inventions in joints and joints of the construction can penetrate.

The Light shaft cover consists of a flat plastic surface, for example made of acrylic glass. On the bottom is the plastic plate on machined metal profile tubes or metal profiles on the the entire width or length of the light shaft cover run and at the ends with on the light shaft frame. The machined profile tubes are not connected to the plastic plate, about the different thermal expansion of the materials not to hinder. The plastic plate of the invention Light shaft cover is at the bottom with a circumferential ridge strip made of the same plastic as the plastic surface, and which is firmly bonded to it with an adhesive. Depending on where the machined profile tubes run are the corresponding ones Make the circumferential ridge strip with a cutout provided that receives the machined profile tubes. These design features ensure optimal static properties.

Around ventilation of the rooms adjoining the light shaft to ensure the inventive Light shaft cover with one or several ventilation openings be provided. The opening can be through a ventilation grille be covered with integrated insect screen to prevent penetration to prevent dirt, insects and small animals.

At The machined profile tubes can be installed an anti-burglar become.

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

1 a view from above of the light shaft cover according to the invention,

2 a top view from below of the light shaft cover according to the invention,

3 a side view of the light shaft cover according to the invention,

4 a cross section of the support / fold ( 8th ) at the light shaft with inserted light shaft cover,

5 a profile tube ( 4 )

6 a commercial ventilation grille ( 2 ).

In the 1 to 4 a light shaft cover is shown whose walk-in area ( 1 ) consists mainly of plastic, preferably acrylic glass. Acrylic glass has advantageous optical and mechanical properties. The glass-like visual appearance and translucence make it a suitable material to achieve the objective of the invention optimal light incidence through the light shaft.

Among the advantageous mechanical properties include hardness and stiffness, which in turn serves the claim of the invention to achieve optimum static properties of the light shaft cover. In addition, they make the Lichtschachtabab Cover resistant to scratches and cracks.

From the plastic surface ( 1 ) can be a ventilation opening ( 3 ), which allows sufficient air circulation through the light shaft. The ventilation opening ( 3 ) can be used with a commercially available ventilation grille ( 2 ) are made of metal with integrated insect screen. Thus, the penetration of leaves, dirt and small animals is largely prevented.

At the bottom is the light shaft cover with a circumferential ridge ( 5 ) made of the same plastic. This raise bar ( 5 ) forms the contact surface with which the light shaft cover on the support / fold ( 8th ) of the light shaft rests. With the strength of the elevation bar ( 5 ), the light shaft cover can be adapted to the individual light shaft so that light shaft and light shaft cover are flush with the surface. In addition, plastic frames ( 5 ) and plastic plate ( 1 ) stick together perfectly. The problems that often arise when bonding different materials and thus form a target for wet and weather conditions, can be eliminated.

2 shows the machined profile tubes attached to the underside of the light shaft cover ( 4 ) made of metal, which serve to reinforce the static. These can be arranged either longitudinally or transversely, depending on the requirements of the light shaft. At the ends go the machined profile tubes ( 4 ) into flat strips which are loosely cut into a cutout ( 7 ) in the encircling listening bar ( 5 ) einliegen. Through the connectionless storage of the processed profile tubes ( 4 ) is an unimpeded expansion or contraction of the different materials of the machined profile tubes ( 4 ) and the plastic surface ( 1 ), as well as the circumferential increase bar ( 5 ).

At least one of the machined profile tubes ( 4 ) has two holes ( 6 ) to allow the installation of burglar alarms.

Instead of profile tubes ( 4 ), other profiles such as double-T-profiles (I-profiles) or U-profiles can be used.
