L E U C H T E N HÄ N G E R A U S L E G E R Type LHA STU HA File number G 7625709.5

The suspension of the headlights to illuminate the decorations in the Film and television studio has so far been fixed, in the horizontal Fixed level, unchangeable fixed points, which are specified by the arrangement of the lamp lifting equipment on the studio ceiling. Here it is unavoidable that in particular large, homogeneous decorative surfaces (Brochures) have shades of brightness in the illumination, which are undesirable.

With the development of the "luminaire hanger ^{bracket i!"} Swivel range of 360 °. By moving the lights to any point, a uniform illumination of the prospectus can now be achieved (see drawing on sheet 1 - assembly drawing).

B. State of the art:

So far, there is no such device in a modified form.

C. Presentation of the deficiencies in previous statements:

The presentation of the shortcomings of the previously known versions is omitted because this device does not exist yet.

D. Task and solution;

The task was to be able to place a lamp for evenly illuminating the decoration at any desired point in the studio.

As a solution, we developed the device "lamp hanger bracket", which, in a greatly simplified manner, consists of an aluminum tube with a total length of 1.6 m, which can be pivoted through 360 °. By combining the corresponding construction parts (see drawing on pages 1 - 4 - Universal joint, weight, tube limiting device, etc.) the prerequisites have been created so that:

1) within the swivel range of 360 ° at a distance of 0 - 80 cm from the pivot point (description of a circular area with a diameter of 160 cm) either on one side with Balance weight on the opposite side or on both sides at any point on the described circular area Luminaires can be hung without inclined loads occurring at the pivot point (horizontal principle).

Would you attach it to every hoist in the studio? The circular description of this would be any point on the studio ceiling in the areas cover to offset the luminaire.

2) all safety-related requirements for use are required in public places of assembly are.

E. Description of the lamp hanger bracket:

The device consists of a 160 cm long aluminum tube (see drawings on sheet 1 and 2, part 1), which at both ends by unscrewable limiting plates (see drawings, sheets 1 and 2, part 2), which prevent the Devices or weights hanging from the pipe can slide off later in the set-up state or in the event of a defect. The pipe is in

Claims (3)

Center equipped with a universal joint suspension (see drawings on sheet and 3, part 3). The limiting sleeve limits the deviation of the aluminum tube from the horizontal to 20 cm at the outermost fastening point. The safety rope with shock absorber (see drawing on sheet 1) prevents and dampens the free fall of the device if the suspension peg is hardly conceivable, but has to be taken into account. The balance weight, which is slidable on one side of the luminaire hanger (see drawings, pages 1 and 4, part 4) ensures that the device is balanced horizontally when the luminaire is suspended on one side (balance principle). Protection claims 1. "lamp hanger boom", characterized in that the basic element part 1 (see drawings sheets 1 and 2) is an aluminum tube to the Pipe ends with limiting plate part 2 (see drawings on pages 1 and 2) is provided, the center suspension part 3 (see drawings on sheet 1 and 3) is made movable and a counterweight part 4 (see drawings on pages 1 and 4) arranged on one side of the extension arm is to use this device to offset a luminaire at any To be able to make point of the studio ceiling. 2. lamp hanger boom "according to claim 1, characterized in that the limiting plate part 2 (drawings sheets 1 and 2) made of steel ST 37, made detachable, the movable center suspension Part 3 (drawings sheets 1 and 3) made of a steel universal joint with 360 ° pivotable pin with steel limiter sleeve and eyelets for attaching the necessary safety devices, so that the device is swiveled through 360 ° in the horizontal plane and a maximum of 20 cm out of the vertical plane at the outermost end of the luminaire hanger Plumb can be lowered, a balance weight part 4 (drawings sheets 1 and 4) made of lead with a tubular steel sleeve and locking device to a to be able to make any shift on the aluminum tube part 1. 7625709 12/30/76 Protection claims 1. "lamp hanger bracket", characterized in that the basic element Part 1 (see drawings on pages 1 and 2) an aluminum pipe to which Pipe ends with limiting plate part 2 (see drawings on pages 1 and 2) is provided, the center suspension part 3 (see drawings on sheet 1 and 3) is made movable and a counterweight part 4 (See drawings on sheet 1 and 4) is arranged on one side of the bracket, so that this device can be used to offset the luminaire at any desired To be able to make point of the studio ceiling. 2.'Leuchten hanger boom "according to claim 1, characterized in that the limiting plate part 2 (drawings sheets 1 and 2) made of steel ST 37, made detachable, the movable center suspension Part 3 (drawings sheets 1 and 3) made of a steel universal joint with 360 ° swiveling pin with steel limiter sleeve and nozzles for fastening the necessary safety equipment exists so that the device is swiveled through 360 ° in the horizontal plane and a maximum of 20 cm out of the vertical plane at the outermost end of the luminaire hanger Plumb can be lowered, a balance weight part 4 (drawings sheets 1 and 4) made of lead with a tubular steel sleeve and locking device to a to be able to make any shift on the aluminum tube part 1. 76? 57Ü9 30 1? 76 3.'licht hanger boom ", according to claim 1, characterized in that a steel shock absorber spring (see drawing sheet 1) hangs in the fastening eyelets part 3 (drawing sheets 1 and 3)
