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

ATTACHMENT MEANS FOR LIGHTING EQUIPMENT

Technical Field The invention relates to attachment means for lighting equipment, especially means for attachment of a lighting equipment to a ceiling or a wall.

Background of the Invention

Lighting equipment utilised for illumination of theatre or show stages, platforms and catwalks, especially equipment of the kind for light effects, are very often mounted on ceilings to avoid obstructions of a view of spectators. The equipment turning and tilting, light beam intensity, or exchange of colour filters or shown images are remote controlled. Mounting of a complete unit, including also control mechanisms and electronics, no matter how miniaturised ones, is very strenuous and takes a great deal of muscle. Maximum strength and effort is need until the unit is attached to the desired place and there is no more danger it falls downs and becomes damaged before being put into operation. Physically less arduous is mounting of a unit of the kind on a wall, but the above presented problems exist here as well and the more effort is to be put in the higher the equipment is to be mounted. Similar problems are to be faced when the equipment is removed for checking, maintenance or repairs.

It is an object of the invention to facilitate mounting and dismounting of lighting equipment on and from ceilings and walls.

Disclosure and Object of the Invention (Summary of the Invention) The foregoing problems are removed by an attachment means for lighting equipment, in accordance with the present invention, the said means comprising a mounting base and an auxiliary base. On the mounting base there are arranged at least three spikes, which are mutually spaced apart and each of them has a head wider than the spike trunk. The auxiliary base, carrying the lighting unit, is provided with cut-outs, the shape of which in its first part corresponds to a size of the spike head and in its following part, extending at least from one side of the cut-out first part, corresponds to a size of the spike trunk. All the cut-outs have the same orientation and their number and arrangement at the auxiliary base correspond to the number and arrangement of the spikes at the mounting base. Further in accordance with the present invention the auxiliary base is provided with at least one quick-clamping element for fixing the lighting unit position at the mounting base. The quick-clamping element may be provided for by a wing-head screw or by a pivot having a cross-pin at its free end, the cross-pin being retractable into a shaped recess in both bases. In a preferred embodiment the mounting base has a shape of one field of a panel-type ceiling. According to the above aspect of the invention there are provided means facilitating any mounting of a lighting unit on a ceiling or on a wall. At first there is mounted only a light mounting base and consequently, very simply by a mere pushing in place and twisting there is attached a complete lighting unit including all accessories as the case may be. The position may be fixed by special means. By dismantling the whole procedure is performed in a reversed order of the above steps. Both the mounting and the dismounting of a lighting unit is a very simple and a very fast process.

Brief Description of the Drawings

By way of examples the invention will be now described with reference to the accompanying drawing. Fig. 1 presents axonometric view of a lighting equipment with a detached mounting base, Fig. 2 shows an A-part of the auxiliary base according to Fig. 1 , the auxiliary base being in the initial mounting position when just pushed on the mounting base and on Fig. 3 there is the A-part of the auxiliary base according to Fig. 1 , the base being in the final mounting position, when fixed to the mounting base by the quick clamping element. Description of a Preferred Embodiment

Referring to Fig. 1 , there is shown a lighting equipment with a remote control of direction of the light beam, designed for applications in TV or theatres and the like. The purpose and the lighting system of the equipment is unimportant for illustration of the invention. A lighting unit 1 comprising a drive 2 and an electronic package 3, are fixed on an auxiliary base 4. By means of the auxiliary base 4 the lighting unit 1 with the accessories is attached at a mounting base 5 which is fixed at a groundwork like a ceiling or a wall. The illustrated embodiment is designed for mounting on a panel-type ceiling. As shown on Fig. 2 and Fig. 3 the attachment means according the invention comprise the mounting base 5 which is adapted for mounting on a ceiling of a panel-type and has therefore a shape of one field of the said ceiling. Dimensional and a peripheral shape of the mounting base 5 depends upon an application and such details with respect to the invention are unimportant. On the mounting base 5 there are mutually spaced apart arranged three spikes 7, each of them having a head 6 wider than a trunk 8. The auxiliary base 4 of the lighting unit 1 is provided with four cut-outs 9 the shape of which combines oval and circular shapes. In its first part the shape of each cut-out 9 corresponds to a size of the spike 7 head 6. In the presented embodiment this cut-out 9 first part has a circular shape with a diameter allowing the spike 7 head 6 to pass through. A following part, being of an oval shape and extending at least from one side of the cut-out 9 first part, has a profile corresponding to a size of the spike 7 trunk 8. Number and arrangement of the cut-outs 9 at the auxiliary base 4 correspond to the number and arrangement of the spikes 7 at the mounting base 5. The oval part may be located only at one or on both sides of the out-out 9 circular part, but the design as well as their orientation are the same by all the cut-outs 9. By the same orientation of all the cut-outs 9 one has to understand that having the auxiliary base 4 with all above described components placed on the mounting base 5 and spike 7 heads 6 protruding through the cut-out 9 circular part, it is sufficient just to turn the auxiliary base 4 slightly in one direction. The spike 7 heads 6 are then in a position within the cut-out 9 oval parts thus preventing unprompted release of the auxiliary base 4 from the mounting base 5. To improve their mechanical strength the cut-outs 9 are reinforced by fixed packing pieces 12 of the same shape as the cut-outs 9. To secure the position of the lighting unit 1 on the mounting base 5 the auxiliary base 4 is furnished with at least one quick-clamping element 10. In the presented embodiment there are applied two such elements. Each quick-clamping element 10 comprise a pivot having a cross-pin at its free end, the cross-pin being retractable into a shaped recess H located in both bases 4,5. The quick-clamping element 10 may be also provided for by a wing-head screw.

The above described design may be used also for mounting of a lighting equipment on a wall with any inclination.

Industrial applications

The present invention is designed for mounting of lighting equipment in theatres, show halls and the like.
