Description

Technical field

The invention relates to a clamping device, in particular a lamp or a wall lamp, such as chandeliers and similar lighting fixtures.

*

BACKGROUND OF THE INVENTION

Ceiling lamps, such as chandeliers and similar devices, are suspended from the ceiling hooks and are connected to the power via various electrical couplings. These are mostly different types of terminal blocks with screws. It is also known to have a drawer in the ceiling next to the ceiling hook and the ceiling lamp is provided with forks. In all these cases it is therefore necessary to install a ceiling hook and an electrical conductor with a terminal block in the ceiling.

A disadvantage of the known solutions mentioned above is the complicated suspension of the ceiling lamps and their subsequent connection to the electric conductor. Removing the ceiling light can cause damage to the ceiling light or cause an electric shock. Another disadvantage is the aesthetic appearance of protruding electrical conductors when the luminaire is removed and the risk of electric shock, such as painting. Another disadvantage is the necessity of using the steps when detecting the luminaire and the subsequent connection of the electric conductors in a too stable position.

Wall lamps are usually connected using different holders, which are non-aesthetic and single-purpose, ie for another lamp it is necessary to use a different holder. When the sleeve is removed, electrical conductors protrude from the wall.

Another disadvantage is the risk of electric shock

-2current when removing the luminaire.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are largely eliminated by the clamping device, in particular the ceiling or wall lamp, according to the invention. Its essence is that it consists of a drawer part formed by an installation box provided with a drawer and stops, and a fork part formed by a cover provided with forks and latches for contact with the stops. The latches are connected via a gear mechanism with an actuating rod _T, a cover made of the forked portion. The latches are preferably rotatably mounted on a cross member within the housing, one end of which is provided with a tooth and a compression spring for contacting the stop in the installation box, and the other end is in contact with the control rod. The control rod is T-shaped. Its shorter arms are in contact with the latches and its longer arm is equipped with a tension spring.

The advantage of this device is above all the easy and safe suspension of luminaires. The drawer part can be fully concealed in the ceiling or wall. If necessary, it can be covered with a suitable cover so that the ceiling or walls, that is, rooms and several sockets that can be used as needed. The luminaire can be suspended simply by sliding the fork part onto the drawer part. By holding these two parts, not only the mechanical contact and the secure suspension of the luminaire are ensured, but also the necessary electrical contact. Enough if necessary! just pull the control rod and the luminaire can be removed. The control rod can be extended so that the luminaire can be removed from the ground without the need for steps. The whole device is relatively simple and can be of a high aesthetic level. V does not disturb the external appearance that it may be in the respective parts at different locations.

- Finally, the safety aspect is also important.

Overview of the drawings

FIG. 1 shows a cross-sectional side view of a fixture of a ceiling lamp according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

The ceiling fixture device consists of a drawer part 1 formed by a circular installation box 11 provided with a drawer 12 at its center. In the wall of the installation box 11 two stoppers 13 in the form of rectangular slots and two shoulder 15 for guiding the fork part are formed.

2. The bottom of the installation box 11 is provided with holes 14 for mounting screws. The circular installation box 11 is supported by a fork portion 2 formed by a cylindrical cover 21 in the center of which are the forks 22 corresponding to the socket 12 and a protrusion 31 is provided on the inner wall of the cylindrical cover 21. One end of the latch 24 is provided with a tooth 30 for contacting the stopper 13 in the wiring box 11 and the other end of the latch 24 is in contact with the control rod 25. The latch 24 is secured by a compression spring 26 positioned between the latch 24 and the central portion of the crossbar 23. The control rod 25 is formed by a T-shaped jig, wherein the ends of its shorter sides are intended to contact the pivot latches 24 and the long arm is slidably mounted on the rod 27 and is provided with a tension spring 28. At its free end the rod 27 is provided with a suitable grip. 29.

In an exemplary embodiment, the socket portion X is secured to the ceiling by screws, the socket 12 being connected to an electrical conductor 16. The luminaire is provided with a fork portion 2 in which the plugs 22 are connected to the light

-4Source. When connecting the luminaire, it is sufficient to simply place the fork part 2 on the drawer part i. The forks 22 fit into the socket 12 and the catches 24 of the fork part 2 engage in the stops 13. Mutual rotation is prevented by insertion of the projection 31 into the shoulder 15. This ensures a secure contact of the electrical conductors, whereby the connection of the socket part with the fork part 2 is sufficiently strong.

If it is necessary to remove the luminaire, it is sufficient to simply move the control rod 25, thereby releasing the latches 24 and the luminaire can be easily removed. If necessary, the rod 25 can be extended to the luminaire itself or under it, allowing the luminaire to be removed and removed without steps. The opening in the drawer part 1 can be easily covered temporarily and permanently. This avoids the risk of injury and the ceiling surface is not disturbed by non-aesthetic hooks and protruding electrical conductors. The shape of the fork part 2 can be adapted to the luminaire or other requirements, while using various construction materials while maintaining safety.

Industrial applicability

The clamping device, especially the ceiling or wall light fixture, will find a wide application especially in the illumination of flats, offices and public spaces.
