Abstract

For attachment of a lighting equipment to a ceiling or a wall, especially for applications at theatre and show stages, there are designed attachment means comprising a mounting base (5) and an auxiliary base (4). On the mounting base there are arranged at least three spikes (7) which are mutually spaced apart and have a head (6) wider than the spike trunks (8). The auxiliary base (4) carrying the lighting unit (1) is provided with cut-outs (9), the shape of which in its first part corresponds to a size of the spike (7) head (6) and in its following part, extending at least from one side of the cut­out first part, corresponds to a size of the spike trunk (8). All the cut-outs (9) have the same orientation and their number and arrangement at the auxiliary base (4) correspond to the number and arrangement of the spikes (7) at the mounting base (5). The auxiliary base (4) is also provided with at least one quick-clamping element (10) for fixing the lighting unit (1) position at the mounting base (5).

Description

MEANS FOR ANCHORING THE LIGHTING BODY

Technical field

The invention relates to means for anchoring a lighting device, in particular on a ceiling or on a wall.

BACKGROUND OF THE INVENTION! Lighting devices used to illuminate stages and stages, especially bodies used for lighting effects, are often mounted on ceilings where they do not obstruct the viewers' view. These devices are controlled remotely, both their filming and inclination, as well as the intensity of illumination, or exchange of color filters or projected images. Assembly of the whole assembly, incl. control mechanisms and electronics, however miniaturized, are very laborious and require considerable physical strength. The most effort is to be made until the whole unit is fixed so that it no longer falls to the ground and thus damage before commissioning. It is physically less demanding to mount the lighting fixtures on the wall, but here too, this is essentially the same problem, and the installation of a complete unit requires considerable effort, the greater the amount of fixation. Similar problems relate to the dismantling of lighting equipment for inspection, maintenance or repair.

The purpose of the invention is to facilitate and simplify the assembly and disassembly of lighting fixtures mounted on ceilings or walls.

SUMMARY OF THE INVENTION

The aforementioned purpose is achieved by means of anchoring an illumination device according to the invention, characterized in that they are provided with an assembly base on which at least three darknesses are spaced apart with a head wider than the darkness shank and further auxiliary a base which carries the lighting fixture itself and is provided with cut-outs whose shape in the first section corresponds to the size of the head of darkness and in the next section, at least on one side adjoining the first section of the cutout; · ·:: ..

The slots are oriented in the same direction and their number and area distribution on the auxiliary base corresponds to the number and area distribution of the mandrels on the assembly base.

Further, according to the present invention, the auxiliary base is provided with at least one quick-release element for locking the position of the lighting body relative to the mounting body. The quick-clamping element may be a thumbscrew or a pivot with a transverse pin at the free end, which can be inserted into the shaped recess in both bases or other means known per se. In a preferred embodiment, the mounting base is in the form of a single coffered ceiling array.

The advantage of the present invention is to significantly simplify the assembly of the lighting device, in which the mounting base itself is first fixed to the ceiling and the entire lighting body, incl. accessories, if any. The position can then be secured by the locking means. The reverse procedure is then used for dismantling. The installation or removal of the lighting unit itself is not only simple but also very quick.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an axonometric view of an illumination device with a separate mounting base; FIG. 2 shows a section A of the auxiliary base of FIG. 3 is a section A of the auxiliary base of FIG. 1, in its final position after being fitted to the mounting base and secured with a quick-release element.

Exemplary embodiment

Giant. 1 shows an illumination device whose purpose and technical solution is not essential to illustrate the present invention. In the present case, it is a lighting device with a remote control which allows the light beam to be directed. The light body 1 itself, together with the accessories including the drive 2 and the electronics block 3, is fixed to the auxiliary base 4 by means of which it is fastened to the mounting base 5 anchored to the base. The shown embodiment is intended for ceiling mounting, on a cassette-type ceiling.

As shown in FIGS. 2 and 3, the means for anchoring the lighting device are constituted by a mounting base 5 which is adapted to be mounted on a ceiling of a cassette of said type and therefore has the shape of a single field of said ceiling. The particular embodiment of the base 5 depends on the application and its details are not essential to the present invention. On the mounting base 5 are spaced apart four darknesses 7 with a head 6 wider than the shank 8 of darkness 7. The auxiliary base 4 of the illumination body 1 is provided with four cut-outs 9, the shape of which consists of an oval and circular profile. The shape of each slot 9 in its first section corresponds to the size of the head 4 of darkness 7.

In the present case, it is a circular shape with a diameter allowing the head 4 to pass through darkness.

In a further, oval section, at least on one side adjacent to the first section of the cutout 9, its profile corresponds to the size of the shaft 8 of darkness 7. The number and area of the cuts 9 corresponds to the number and area of the mandrels 7. The same orientation of the slots 9 means that after the attachment of the auxiliary base 4 with the accessories to the mounting base 5, when the heads 6 of the mandrels 7 have passed through the circular section of the slots 9, the auxiliary base turn base 4 in one direction. The heads 6 of the mandrels 7 are then in the position defined by the oval section of the slots 9 and spontaneously prevent the auxiliary base 4 from moving away from the mounting base 5. To increase the strength, the slots 9 are reinforced with an equally shaped shim 12.

To secure the position, the auxiliary base 4 is provided with at least one quick-release element 10 for arresting the position of the illumination body 1 with respect to the mounting base 5. In this case two quick-release elements 10 are used. both bases 4.5.

The quick-clamping element 10 may also be a thumbscrew.

A similar solution can be well used for wall mounted lighting fixtures.

Industrial applicability

The invention is intended for the installation of lighting devices on ceilings, in particular for the installation of lights intended for the lighting of stages and stages.
