Stand for electrical apparatus.

The present invention relates to a stand for electrical apparatus, preferably lamps for workplaces.

Stands for workplace lamps, especially table lamps, often consist of an arm with articulated parallelograms and exposed springs to balance the weight of the lamp is provided. A disadvantage of such tripods is that the work on the workplace requires every precise setting of the Lamp has to be interrupted, and that the same are often unstable after a short time, especially when wearing electrical apparatus that are relatively heavy. Besides that parallelogram stands are usually sensitive to shock, and difficult to keep clean.

The present invention provides to eliminate the above-mentioned disadvantages and to produce a tripod that is easy and accurate is adjustable with a handle that remains in the set position that is robust, to a modem equipped Workplace fits and can be easily kept clean.

These advantages become main in accordance with the invention achieved in that a stand can be moved up and down Has runner which is provided with an arm supporting the electrical apparatus and its weight with a balancing device is balanced, the runner from external parts and a balance weight of the balancing device be guided by internal parts of the stand. "

The invention is described in more detail below with reference to the accompanying drawings, wherein

Figure 1 is a side view of the subject of the invention shows;

FIG. 2 shows a part of the subject matter of the invention in an enlarged manner Scale shows;

FIG. 3 shows a section along the line III-III in FIG shows;

FIG. 4 shows an upper part of the subject matter of FIG Rear shows;

FIG. 5 shows the upper part of the subject matter of the invention from the front shows;. . .

Jligur. 6 schematich the course of fine electrical conduction for an electrical apparatus carried by a tripod.

_; The. Figures show a stand which has a stand Ϊ on which a runner 2 is arranged so as to be movable up and down. At

an arm 3 is arranged on the rotor 2 and extends horizontally carries an electrical device, preferably a fluorescent tube lamp. About the weight of the runner 2, the arm 3 and the lamp to balance * a balancing device 5 is arranged, with a balancing weight 6 of the balancing device 5 from the inside Parts and the runner are guided by outer parts of the stator 1.

A simple and stable device is achieved in that the stand 1 has two opposing guides la, Ib has engage in the rollers 2a, 2b, 2c of the rotor 2, wherein the rotor 2 has at least two rollers 2b, 2c behind the stand 1 and in front of it in relation to the lamp 4 the stand 1 has at least one roller 2a. The one behind the stand 1 arranged roller 2b is higher than that Connection parts of the arm 3, the other roller 2c behind the stand 1 is lower than the connection point and the one in front of the Stand 1 arranged roller is at the same or mainly the same height as the connection point.

In order to make the rotor 2 light and nevertheless stable, it consists of a rear housing 2d with the two Castors 2b, 2c and a forwardly projecting housing 2e with the front castor 2a.

The rotor 2 can be arranged on the stand 1, or removed from the stand, particularly easily. this will achieved in that the runner 2 is placed from above on the stand 1 and a Unroll.sdes runner 2 is achieved by a Cover 15, which is placed on the stand 1, prevents.

To arm 3 on the runner at any time with a simple

Attaching and removing the handle without the need for a connecting line extending through the arm 3 and the runner 2

7 of the lamp 4 prevents this, is a plug contact device

8 which is automatically connected when the arm 3 is attached and disconnected when the arm 3 is removed. The plug contact device 8 consists of a socket 8a on the rotor 2 \ and a matching plug 8b on the arm 3. The plug 8b is automatically controlled into the socket 8a and this is achieved by attaching the arm 3 to the rotor 2. For attaching the arm 3 on the rotor 2, a threaded sleeve 9 is arranged on the arm 3, which is threaded onto a; the end part 2n of the rotor 2 is screwed and the arm 3 | holds on to rotor 2. The sleeve 9 also serves, together with the axes 2h, 2k and 2m, to hold together two rotor halves 2f, 2g, which form the rotor 2. 2k serve as screws. "-:" ¹

In the illustrated subject matter of the invention, the up and down j

ι movable device consisting of the runner 2, the arm 3 and j 4 lamp not with fluorescent heavy ballast; tube loaded, but the throttle is used as a counterweight 6 j used or connected to the counterweight 6, the counterweight via a line part 7a, which is via a roller la runs in the stator 1 and is connected to the rotor 2. Here, the lines run over from a power source 11 a switch 10 and via the choke 6 to the lamp 4 according to FIG. 6.

In order to be able to extend arm 3 as desired, the same exists of at least two intermeshing slidably

Pipes 3b and 3c wherein the part lying in the pipes 3b, 3c 7b of the line 7 runs in a spiral to enable the arm extension without the line 7 being able to be damaged.

The stand 1 preferably has a clamping device 12 in order to attach the stand 1 to a table top 13 can, wherein the stand 1 is rotatably mounted on the clamping device 12. This allows the lamp 14 in different Positions in relation to the table top 13 can be set and the lamp 14 can also be in different positions be adjustable in relation to arm 3. This is made possible by a hinge device 14 known per se, through which the lamp is arranged on the arm 3.

The subject matter of the invention can vary within the following claims. For example, the fluorescent tube lamp may consist of an incandescent lamp, or the arm 3 may carry an electrical apparatus other than a lamp,
E.g. electrically powered devices that are fixed or detachable on the arm.
