Claims
1. Electrical connection for a roof window which makes it possible to supply electricity from the source of power supply to the electrical device installed on the sash, characterized in that it is composed of two parts, one of which is mounted to the window frame /3/ and connected by an electrical cable to the power source, while the other part is mounted to the sash frame IAI and connected by an electrical cable to the electrical device installed on the sash, whereas both parts by means of contact elements 121, /6/ come into contact when the window is being closed and remain in contact in the closed window position, conducting electric current from its source to the device installed on the sash.
2. The electrical connection according to claim 1 , characterized in that the part attached to the window frame IZI, of advantageous wedge-like shape IV, has sliders 121, while the part mounted to the sash frame IAJ has flexible contacts 16/, with the advantageous spherical contact tips IJJ on their free ends.
3. The electrical connection according to claim 1 or 2, characterized in that the contacts IQI are shielded by the guard /5/. |
Electrical connection for a roof window
The subject of the invention is an electrical connection for a roof window consisting of a frame and a swinging or tilting/swinging sash with an electrical device installed on it, in particular the driving mechanism of a roller blind or a Venetian blind. When the window is closed, the electrical connection provides a safe and reliable supply of electricity to the electrical device installed on the window sash.
There is known a solution of a roof window with a roller blind with a drive mechanism installed on its sash. The mechanism is supplied with electricity through a cable running from the power source along the window frame and to the pivoting hinge on which the sash is mounted. Then, the cable follows the frame of the sash to the drive of the roller blind. Where it crosses the gap from the window frame to the sash, in the approximate middle of the window height, a cable section sufficiently long is provided so that the window sash can be turned almost 180°. The loose section of the cable is held in a plastic casing whose one end is fixed to the window frame and the other to the sash. The casing is to protect the cable from mechanical damage by holding the cable in the correct location relative to the hinge. During window closing, the casing is folded on articulated joints into a package arranged between the window frame and the sash in the closed window position. The plastic casing has a limited durability and its multiple folding and unfolding during window use damages it, thus exposing the cable supplying power to the roller blind drive mechanism.
The purpose of this invention is to provide an electrical connection for a roof window comprising a window frame and a swinging or tilting/swinging sash with an electrical device installed on it, which connection provides a safe and reliable electrical power supply to that device when the window is closed but does not restrict the functionality of the window and makes it possible to detach the sash
from the frame without disassembling the electrical wiring that supplies electrical power to the device installed on the sash.
The electrical connection invented comprises two parts mounted, respectively, on the window frame and the frame of the sash. The connection part mounted on the window frame is connected to the power source by an electrical cable, while the part mounted on the sash frame is connected by a cable to the electrical device installed on the sash. Both parts of the connection have contact elements which are pushed against one another during window closing and remain in contact in the closed window position, allowing electric current to flow from the power supply source to the device mounted on the sash.
In the open window position, both parts of the connection are removed from each other and the electrical circuit connecting the electricity source to the device installed on the sash is broken. When the window is being closed and the sash gets close enough to the frame, both parts of the electrical connection come into contact, for example by the tight pressing of the contacts against each other, thus closing the electrical circuit and allowing electricity to flow from the power supply source to the device installed on the sash.
Embodiments of the invented electrical connection are shown in drawings. Fig. 1 shows the roof window equipped with a sliding contact connection, Fig. 2 - a fragment of the window frame with a part of the electrical connection mounted to it, Fig. 3 - the first design option of the sash fragment to which a part of the connection is attached, Fig. 4 - the cross-section of these elements, Fig. 5 - the second design option of the sash fragment to which a part of the electrical connection is attached, and Fig. 6 shows the cross-section of these elements.
Example I
The electrical sliding contact connection is composed of a wedge-shaped part 1, with two parallel sliders 2, mounted in the upper element of the window frame 3, and two parallel, flexible, convex contacts 6, with spherical contact protrusions 7 on their free ends, attached to the upper part of the sash frame 4, within the guard 5.
During window closing, the spherical protrusions 7 of contacts 6 slide onto the sliders 2 and by being flexibly pressed against them, close the electrical circwt During the slight (partial) opening of the window, the spherical protrusions 7 move along the sliders 2 so that if the opening angle is small, the electrical circuit remains closed.
Example Il
The electrical sliding contact connection is composed of a wedge-shaped part
1, with two parallel sliders 2, mounted on the window frame 3, and two parallel, telescopic, spring-loaded contacts 6, with spherical tips 7 on their free ends, attached to the sash frame 4, inside the guard 5.
During window closing, the tips 7 of contacts 6 slide onto sliders 2 and by being flexibly pressed against them, close the electrical circuit.
During the slight (partial) opening of the window, the tips 7 of contacts 6 move along the sliders 2 so that if the opening angle is small, the electrical circuit remains closed.
