ⁿ basement window light shaft "

The invention relates to a kit for a basement window light shaft.

Basement window light shafts are particularly needed if the basement windows are at least partially below the floor level surrounding the building · Up to now, such!]

Light shafts made of masonry or poured from concrete or the like. Such light shafts are relatively complex and expensive. In addition, when a new building is being built, it is often not possible to precisely predict the height at which the ground level will run. It is therefore often subsequently necessary to change the amount of light wells _s what in the known basement window light excavate is possible only with considerable difficulty.

The invention is based on the object of a basement window light shaft to create that is easy to set up and can be retrofitted without great effort, even by a non-specialist can be adjusted in height

According to the invention, this object is achieved by a new type of kit consisting of plastic parts. The kit includes a one-piece, box-shaped shaft part, which is open on one side and up and down and to the free End edges of the walls adjoining the open side laterally angled flanges for attaching the shaft part to a has a house wall surrounding a basement window, as well as a box-shaped one also made in one piece from plastic Attachment part with side walls that enclose essentially the same outline as the shaft part and form-fit in the Engage part of the manhole or overlap the manhole part, with

the upper edge of the attachment part has a circumferential, outwardly projecting flange, which is of a circumferential, the Outline of a grating adapted edge strip is surrounded.

When assembling the basement window light shaft according to the invention, the shaft part is first placed before the Soil, for example, with the help of screws and dowels in the area of the cellar window in question, attached to the masonry After the earth has been filled up, the attachment part is put on, which can be freely displaced relative to the shaft part is. The protruding flange provided on the upper edge of the attachment part rests on the specified floor level and thus adapts to the resulting floor height at. If necessary, the flange can be underlaid with a few bricks to better hold the attachment part · The The top part also adapts without any problems to a floor level that is sloping relative to the house wall. After the attachment has been installed, a grating known per se can be placed on it which is fixed in its position by the edge strip running around the flange

The attachment part will preferably be designed in such a way that it can be inserted into the shaft part «

The side of the attachment which is the open side of the shaft is partially assigned, can just as much as the shaft part itself

be open. In order to have a support for the grating in the area of the open section, the

i open side one provided with a T-profile, the length of the open one Side adapted steel rail be provided, with the opposite sides of the attachment each at its upper end a slot for receiving a flange part of the T-profile exhibit. The attachment part can act as a support surface for the web of the T-profile;) on each side of the respective Have receiving slot in the direction facing away from the open side subsequent step-shaped shoulder, so that the top of the web serving as a support is at the same height the laterally protruding flange of the attachment part

To facilitate the storage of the parts of the plan view of the box-shaped chute portion as well as deo attachment portion may be trapezoidal, wherein the longer base of the trapezium is located in the open side of the chute portion. This allows the parts to be easily plugged into one another.

If the building is surrounded by a gravel embankment, it can the lower end of the shaft can be designed as a simple layer of gravel into which the rainwater seeps. Otherwise a separate, also made of plastic, flat floor board can be provided, the outer circumference of which corresponds to the interior j outline of the shaft part is adapted and the lower Ab- ι Can form the end of the shaft. For fixing the floor board

■ suffered

in the shaft part this can be in the opposite side from the open side Side wall have at least two recesses provided at a distance at the same height, into which the retaining pegs provided on the bottom board engage. To a height adjustability To ensure the floor board, the shaft part can have several recesses provided at different heights have for optional insertion of the pegs of the floorboard. The bottom board, which i? I built-in state to the n * it the tenons provided side is inclined obliquely downwards, preferably has at least on the side provided with the retaining pin a recess through which rainwater penetrating the light shaft can seep into the ground. On the the retaining pin opposite side, the bottom board can have a stepped shoulder on its underside, with which it can be adapted to the basement window in the correct shape.

To the shaft part made of relatively thin-walled plastic To give the necessary support, the side walls of the shaft part can have reinforcing ribs running parallel to the top and bottom exhibit. So that the reinforcing ribs do not rest against each other when stacking the same parts and the To increase the stacking height unnecessarily, the reinforcement ribs can alternately rip be provided on the inside and outside of the side walls.

To prevent rainwater and dirt from getting between the mounting flanges and the masonry penetrates into the light shaft, two sealing strips can be provided the installation of the light shaft between the mounting flange and the masonry.

Furthermore, on the lower edge of the attachment and if necessary be attached to the free vertical edges of the side walls, a sealing profile, which also dirt and Keeps rainwater away from the shaft.

To attach a holder for the grating, in the side walls of the shaft part from the interior of the shaft part accessible threaded bushings are cast, which preferably are attached in the area of a reinforcement rib.

The invention is illustrated by way of example in the drawing and is described in detail below with reference to the drawing. Show it:

The shaft part 2 is essentially box-shaped and is open to one side as well as to the top and bottom. As can be seen in particular from Fig. 3, the shaft part has a trapezoidal plan, the longer base * line of the trapezoid lies in the open side of the shaft part. At the free end edges of the one adjacent to the open side Side walls 14 are provided with two laterally angled flanges 16 which each have at least two fastening holes 13.

For reinforcement, aas shaft part 2 has several circumferential ribs 2o, which alternate on the inside and outside of the Side walls are provided.

The side wall 22 opposite the open side is on

their opposite ends are provided with recesses 24 at different heights, which are provided for the optional insertion of the floor board 8. For this purpose, the bottom board 8 has corresponding retaining pins 26 which are inserted into the recesses 24. On the side provided with the retaining pin 8, the bottom board further comprising a approximately over the entire length of the floorboard extending recess 28, which in the inserted state of the od ^B <? ν retts forms a gap between the inside of the side wall 22 of the shaft part 2 and the bottom board 8 through which rainwater and dirt particles that have penetrated into the light shaft can seep

The bottom board 8, which has a stepped shoulder 3o on the side opposite the retaining pin 26, is placed flush with this on the masonry forming the lower end of a basement window, with the pin 26 in one
