Definitions

  • the invention relates to an electric lamp with a frame which carries a light source and consists of arms which are connected to one another via double joints with parallel pivot axes directed transversely to the arms.
  • an electric lamp of this type is known from DE-OS 32 14 651.
  • the arms from which the lamp frame is composed consist of tubes which are connected to one another at their ends, which can be bent at right angles, by means of mounting parts.
  • the ends of the adjacent tubes are inserted parallel to one another into cylindrical openings in the associated holding part, so that they can be pivoted relative to one another.
  • the bracket parts consist of half shells that are clamped together by screws.
  • the electrical lines for supplying the current to the light source run inside the tubes, connecting plugs being arranged in the holding parts.
  • a lamp with two parallel hinge pins is also described in DE-OS 26 27 514.
  • the arms of the The lamp frame is only connected to one another by the one hinge pin, whereas the second hinge pin is provided for the articulation of a spring compensation rod.
  • the lamp frames with compensating springs are complex and bulky. They also look ugly, as additional springs are provided in the area of the joints to hold the arms and power lines bridging the joints.
  • the invention has for its object to improve the previously known electric lamps with pivotally connected arms so that the adjustment options of the lamp frame and thus the light source are significantly expanded and still get a lamp with an attractive shape, the spatial shape can be changed many times .
  • each double joint consists of its own hinge pins, each anchored at the end of an arm transversely and symmetrically to its longitudinal axis and connected to one another via lamellae.
  • This design and arrangement of the double joint ensures that it does not lie laterally next to the arms of the lamp frame, but rather is largely integrated into the lamp frame.
  • the individual double joints are therefore inconspicuous and enable the lamp to be designed aesthetically without restricting the functional variation possibilities of the lamp given by the joints.
  • this double joint it is possible to pivot the arm equipped therewith or the adjacent arms connected thereto by an angle of up to 360 ° with respect to one another.
  • the lamp frame can be completely folded due to this design, so that the lamp can be accommodated in the smallest space, for example when it is not being used.
  • Double joints and joints with a plurality of joint pins arranged parallel to one another are known per se.
  • a joint for a folding chair is described in US Pat. No. 4,684,278 in which three adjoining arms pass through a total of four parallel pivot pins are pivotally connected to each other.
  • From DE-OS 23 12 315 a hinge connection of a linkage to a lever is known, in which a hinge pin is mounted in a U-shaped fork head, which is fastened with the aid of a threaded nut to the end of a linkage.
  • a presentation frame for displaying goods is known in which adjacent wall parts are connected to one another by double joints, lamella-like connecting plates being used.
  • a preferred embodiment of the lamp according to the invention consists in that, with arms of the same width, the distance between the pivot axes formed by the pivot pins of a double joint corresponds to the arm width.
  • the arms of the lamp frame can be folded in parallel next to one another and adjoining one another. When folded, the lamp forms a package of arms lying parallel one above the other.
  • an advantageous embodiment of the double joint consists of joint pins, each with their ends are held in a joint carrier with fork-shaped legs connected to an arm of the frame and do not have openings between the fork-shaped legs in the slats and in the busbars.
  • the pivot pins and the fork-shaped legs of the joint supports can be electrically insulated from the slats and the busbars by plastic washers and bushings inserted between the individual parts. The manufacture and assembly are made considerably easier if the joint supports are divided in a plane perpendicular to the pivot pins.
  • the hinge pins can be fastened to the hinge supports by means of nuts which are arranged at least partially countersunk in recesses in the legs of the hinge supports and are preferably cylindrical.
  • This configuration also facilitates the assembly of the double joints, which are merely screwed together. Through the screw connection, the lamellae, busbars and insulating washers lined up on the pivot pins are pressed against one another and against the joint carrier, so that the internal friction of the joints can be changed and adjusted by appropriately tightening the nuts. By countersinking the nuts, protruding parts that could hinder the adjustment of the arms and also look ugly are avoided.
  • Counter nuts can also be provided, which are also expediently countersunk in depressions in the main nuts.
  • the busbars of successive double joints can be connected to one another by power lines running in a conventional manner inside the hollow arms of the frame.
  • the busbars can be provided with connecting lugs to which the power lines can be connected or soldered.
  • the lamp and in particular of the frame are possible, which consists of adjoining arms which are connected to one another by double joints. If the swivel axis of all double joints between the arms of the frame in the all arms can be swiveled in one plane. It is then possible to fold the lamp frame in such a way that all the arms lie parallel to one another.
  • the pivot axes of the double joints which are formed by the pivot pins and are anchored at the ends of the same arm, run in different directions, preferably they cross each other at right angles.
  • the successive arms can be pivoted in different planes that are inclined towards each other. With swiveling axes crossing each other at right angles, the arms of the lamp frame can be folded together to form a package in which the arms lie side by side and against one another in two or more layers.
  • the arms of the frame can be curved between two double joints, e.g. be circular arc-shaped.
  • the arms of the frame are rotated between two double joints in each case about an axis running in their longitudinal extent, preferably by an angle of rotation of 90 °. This has practically the same effect as with training with double joints, the pivot axes of which run in different directions.
  • the variety of the design possibilities of the lamp frame created by the invention can also be increased in that a plurality of double joints directly adjoin one another without the interposition of arms. This results in an articulated chain between the adjacent arms of the frame, which not only makes multiple adjustments possible, but is also advantageously suitable for the aesthetic design of the lamp.
  • the light source can be integrated into the lamp according to the invention.
  • the light source is preferably designed in the form of an arm of the frame or installed recessed in an arm.
  • the lamp frame can then be folded into a package without being obstructed by a bulky light source.
  • Another design option for the lamp according to the invention results from the fact that the two joints of the double joint can be of different sizes. Even with this, the appearance of the lamp can be changed without impairing the function.
  • the lamp frame 1 consists of an elongated base 1, on which a lamp frame 2 is anchored via a simple joint 3.
  • the lamp frame 2 consists of three rod-shaped arms 4, which are each connected to one another via a double joint 5.
  • a light source 6 is integrated in the arm 4, which can be rotated about the longitudinal axis of the arm 4 within a range delimited by a lock. With 7 the power cable for the energy supply to the light source 6 is designated.
  • Each double joint 5 consists of two joint pins 8 and 9, each of which is fastened at its ends in a joint carrier 10 and 11 connected to an arm 4 of the frame 2.
  • the articulated supports 10, 11, which can be separated into two parts perpendicular to the articulated pins 8, 9, have legs 12, 13 arranged in the form of a fork, in which bearing bores are provided for the articulated pins 8, 9. Between the legs 12, 13, each pivot pin 8, 9 passes through two fins 14, 15 and two associated busbars 16, 17. Each lamella 14, 15 bears against a busbar 16, 17 and is therefore in an electrically conductive connection with the latter.
  • the busbars 16, 17 are fixed by holding frames 27 made of insulating plastic, which are inserted into the joint supports 10, 11, and are kept at a distance from the joint supports 10, 11.
  • the arms 4 of the frame 2 can be pivoted against one another by an angle of approximately 360 ° by means of the double joints 5 provided between them.
  • the arms 4 can be pivoted into any position in one plane, so that it is possible to give the lamp different shapes.
  • the arms 4 can be folded so that they run parallel to each other, and all the arms 4 can be folded in parallel on the base 1. In this collapsed state, the lamp takes up only a small space, so that it can be easily stored and transported.
  • the frame 2 also consists of arms 4, which are connected by double joints 5.
  • the pivot axes of the double joints 5 which follow one another over the length of the frame 2 run there in such a way that they cross one another at right angles.
  • the arms 4 can be pivoted not only in a vertical plane, but also horizontally and in inclined planes.
  • the possibilities of varying the shape of the lamp frame 2 are thereby multiplied. Nevertheless, this lamp can also be folded into a small space, as shown in FIG. 5, where the individual rods run side by side in two rows.
  • the lamp shown in FIGS. 6, 7 and 8 is designed similarly to the embodiment according to FIGS. 4 and 5. Also in this variant, the successive arms 4 are alternately connected to one another by double joints 5, the pivot axes of which cross each other approximately at right angles.
  • the lamp consists only of the frame 2 formed from the arms 4, the lower end of which can be shaped in such a way that it forms a base for setting up the lamp, as shown in FIG. 6.
  • the lamp frame 2 is shown on a dot-dash line Box 24 suspended, the successive arms 4 are aligned with each other so that they lie securely on the box 24 and the lamp frame 2 is firmly anchored.
  • Fig. 8 shows the same lamp in a folded state to form a package, the individual arms 4 with the double joints 5 lying parallel and one above the other.
  • the 9 has arms 4, which run between the double joints 5 in a circular arc.
  • the base 1, on which the lowermost arm 4 of the frame 2 is fastened via the simple joint 3, has a correspondingly curved shape.
  • the frame 2 can be folded down on the curved base 1 due to the double joints 5, the arms 4 lying parallel above one another.
  • the frame 2 can also consist of several arms 4 which connect to one another via double joints 5, as shown in the drawings.
  • the exemplary embodiments show that the design of the lamp according to the invention enables practically unlimited variations in the shape of the lamp, whereby for all training variants practically the same few and simple components are used.
