Description

75647

The present invention relates to a window bench / which is intended to be fixed to the inner wall of a building under a window 5.

In residential and office buildings, the window surface is usually colder than the wall surface in winter, as a result of which traction is created in the interior. In addition to being uncomfortable, the traction causes unnecessary energy consumption, as the radiators often have to be kept unnecessarily hot considering the room temperature, so that the traction can also be largely eliminated. Strain relief with conventional radiators does not always work satisfactorily, as there are often various obstacles above the radiators, such as window sills or benches.

In the renovation of houses, it is very common to place a thermal insulation layer on the inner surface of the wall. As a result, the radiators are moved away from the windows, which reduces their anti-traction effect.

It is an object of the present invention to provide a device by means of which traction can be effectively prevented. The invention is characterized in that the window sill has heating elements.

By equipping the window sill with heating elements, the traction caused by the windows can be effectively prevented, because there are no obstacles of any kind between the flow of warm air between the window-25 bench and the lower edge of the window.

In order for the window sill to heat the air as efficiently as possible, it is preferred that the heating means are located in the cavity of the bench with air inlets and outlets.

30 In a window bench constructed in this way, air can flow through the bench.

If the heating effect of the window sill is to be as even as possible, a plate of heat-storing material can be placed above the cavity. If, on the other hand, it is desired to prevent the upper surface of the window bench 35 from heating up, it is preferred that the panel be a heat insulating material.

The strain relief effect of the window bench can be enhanced by the air inlets being located at the bottom of the bench at least at the edge remote from the window and by the air outlet being located close to the window at the edge of the bench.

The window sill according to the invention will now be described in more detail with reference to the accompanying drawing, in which Fig. 1 shows a window sill according to the invention seen from the front, Fig. 2 shows the window sill as a side view, Fig. 3 and Fig. 5 shows a section according to Fig. 4 of a second embodiment.

The drawing shows a window bench 1, which is fastened to the wall of the building at the window 4 and to a lower level by means of brackets 2 and 3.

According to the invention, the window sill has heating elements formed in the heating cable 5. The heating cable 5 is fixed by fastenings 6 to the inner surface of the base plate 7 of the window sill and is connected to the network via a plug or switch.

As can be seen in particular from Figure 4, the window sill is box-shaped with the heating cable 5 located in the cavity 8 of the bench. The upper part of the bench is formed by a cover plate 9.

In order to provide air flow through the window bench cavity 8, the bench base plate 7 is narrower than the cover plate 30 9 / U-shaped in cross section, with air inlets 10 and 11 formed at the bottom edges of the bench. , which act as air outlets. The openings can be replaced by a uniform gap.

The window sill according to the invention is installed in place, for example, as shown in Figure 2. Figure 2 shows an additional insulating layer attached to the inner surface of the wall. When the power is connected to the heating cable 5, the air in the cavity 8 5 heats up, as a result of which warm air begins to flow out of the openings 12 and colder replacement air flows inside the slots 10, 11. The warm air flow effectively prevents the window draft.

Figure 5 shows an alternative embodiment 10 in which the cavity 8 is relatively small and the cover plate 9 is replaced by a plate 13, which may be a heat storage substance known per se or alternatively a heat insulating substance. In the former case, the window sill dissipates heat relatively evenly even when the heating-15 cable is not connected to the mains. In the latter case, the insulating material prevents the upper surface of the window sill from heating up.

In addition, the embodiment according to Figure 5 has only one cold air inlet slot, namely a slot 10 remote from the window.

By way of derogation from the above, the heating cable 5 can be placed in a homogeneous casting mass and the cavity 8 can be omitted.
