Definitions

  • the invention relates to an electric scissor lattice lamp.
  • Electric lights are known in which a light source is attached to one end of a scissor lattice, the other end of which is fixed, possibly pivotable. The position of the lamp in the room can be changed by pushing or pulling it apart and by pivoting the scissor grid.
  • the illuminant is connected to a power source via a cable that runs along the scissor lattice.
  • Scissor lattice lights are also known, which are designed as horizontally extendable hanging lights.
  • a lamp is attached to several links of a horizontally extending scissor lattice, which form a compact lamp arrangement when the scissor lattice is pushed together and form a straight row of lamps when the scissor lattice is pulled apart.
  • an extendable table are always illuminated evenly.
  • the invention is to remedy the situation and improve an electric scissor lattice lamp so that an extendable lamp with reduced manufacturing costs few visible electrical connection elements is created.
  • an electric scissor lattice lamp in that it has two identical scissor lattices made of electrically conductive material which run parallel to one another and are each connected to one of the poles of a low-voltage source and the articulation points of which are opposite each other, with at least two articulation points opposite one another being provided with sofa connections and are connected to each other by a small incandescent lamp.
  • a scissor lattice lamp designed according to the invention is easy to produce owing to its relatively simple construction and, apart from the two scissor lattices themselves and their connection to a low-voltage source, has no further electrical connection means which have to be routed to the individual lamps. Therefore, with this scissor lattice luminaire, no cables running along the scissor lattices disturb the visual impression. Because two parallel scissors grids made of electrically conductive material are used, the supporting structure of the lamp can also be used as its electrical conductor in order to supply the lamps with current. There is no safety risk for users of the luminaire because the scissor lattices are only connected to a low voltage source.
  • the parallel scissor lattices are arranged so that their hinge points are opposite each other and can be used to connect lamps. It is envisaged to provide those articulation points that are intended to receive lamps with Sofitten connections and to connect them with each other by means of Sofitten incandescent lamps, which enables an equally simple and inexpensive installation of lamps. But it is also possible to replace the Sofitten incandescent lamps with other, similar lamps.
  • the scissor lattices preferably consist of electrically conductive metal. With the use of this inexpensive material, the manufacturing costs can be reduced even further.
  • the articulated points lying opposite one another and not connected to one another by Sofitten incandescent lamps are connected to one another via electrically insulating spacers.
  • the stability of a scissor lattice light according to the invention from the scissor lattice level is considerably increased, and at the same time unscheduled stresses of Sofitten incandescent lamps are greatly reduced due to a possible lateral migration of the scissor lattice when it is pushed together or pulled apart.
  • a number of articulation points located one behind the other in the pull-out direction of the scissor lattices are connected to the articulation points located opposite each other by means of soft incandescent lamps. This makes it possible to change the length of the illuminated area by pushing or pulling apart the scissor lattice to the changing circumstances, such as. B. the length of an extendable table, easy to adjust.
  • a row of articulation points lying on the outside in the plane of the scissor lattice is particularly preferably connected to the articulation points located opposite each other by means of Sofitten incandescent lamps.
  • the electric scissor lattice lamp is connected to a 12 volt voltage source.
  • This allows common 12-volt lamps, such as. B. 12 volt halogen bulbs, as a lamp can be used for the electric scissor lattice light according to the invention.
  • the scissor lattices are advantageously part of the supporting structure of the scissor lattice lamp. With this configuration, the scissor lattice lamp can be designed in a particularly cost-effective and structurally simple manner.
  • the electric scissor lattice lamp 1 shown in FIG. 1 has two identical scissor lattices 2, 3 running parallel to one another and made of electrically conductive metal.
  • the scissor lattices 2, 3 consist of individual flat, flat bars 4, which are articulated in the middle 5 and at their two ends 6 to the adjacent bars 4.
  • Each scissor lattice 2, 3 is provided at its two ends with a short rod 4a which connects the middle 5 of the last or end rod 4 b with one end of the penultimate rod 4 of the same orientation in an articulated manner. This leaves one end 6a of the end bar 4b free.
  • the rods 4, 4a, 4b are provided with bores, the bores of the rods 4, 4a, 4b to be connected lying one above the other and by connecting means, such as. B. screws 7 or rivets 8 are run through to establish the articulation.
  • the interconnected rods 4, 4a, 4b touch each other so that the electrical conductivity is ensured.
  • the scissor grids 2, 3 are arranged so that their corresponding hinge points 5, 6 lie opposite one another.
  • a continuous row 9 in the pull-out direction of the scissor grids 2, 3 one behind the other and in the scissor grid plane outer articulation points 6 is provided with Sofitten connections 10 in the form of hollow rivets 8, into each of which one end of a Sofitten light bulb 11 is inserted, these opposite articulation points of the scissor grids 2 , 3 are connected to each other by Sufitten incandescent lamps 11.
  • the other mutually opposite hinge points 5, 6 of the scissor lattice 2, 3 are interconnected by electrically insulating spacers 12, so that the spatial stability of the scissor lattice lamp 1 is ensured.
  • the spacers 12 are held between the scissor grids 2, 3 by means of screws 7 which pass through the bores in the bars 4, 4a, 4b and thus simultaneously form the articulation in these articulation points 5, 6.
  • the respective free end 6a of the end bars 4b is connected via electrical connection means 13 to a low-voltage source (not shown).
  • the scissor lattices 2, 3 thus serve not only as a pull-out or collapsible support structure of an electrical light, but also as its electrical conductor, via which the lamps 11 are supplied with current.
  • the scissor lattice lamp 1 from Fig. 1 is shown as a horizontally aligned hanging lamp. It is suspended in height-adjustable manner from a fastening device 15 (only shown schematically) by cables 13 acting on the upper hinge points 6 of the end rods 4b of the scissor grids 2, 3. Overall, the scissor lattice lamp 1 is thus suspended from four cables 13, ie at both ends of each scissor lattice 2, 3, only one of the scissor lattices lying one behind the other and its two cables being visible in the side view of FIG. 2.
  • the fastening device has four rollers 15a, which are at a distance from one another in the plane of the drawing and perpendicular to it are arranged.
  • the two cables 13 of a scissor lattice 2, 3 run up to one of two rollers 15a opposite each other parallel to the plane of the drawing, and down again to a counterweight 14 which lies between the fastening device 15 and the scissor lattices 2, 3 and through which vertical shift the height of the scissor lattice lamp 1 is adjustable.
  • the rollers 15a are made of electrically conductive material and are electrically insulated from one another.
  • a low-voltage source (not shown) in the form of a transformer is arranged in the fastening device 15, two rollers 15a lying opposite one another parallel to the plane of the drawing being connected to one pole of the low-voltage source and the other two rollers 15a being connected to the other pole of the low-voltage source.
  • the four cables 13 running over the rollers 15a are bare and, by touching the rollers 15a, serve as the electrical connection means in addition to the fastening of the scissor lattice lamp 1.
  • the designed sofa connections 10 can be seen, which accommodate the sofa light bulbs 11.
  • electrically insulating spacers 12 are attached in the lower row of articulation points 6, 9 between the articulation points 6a at the ends of the scissor lattices 2, 3 and between the articulation points 5, 6 of the middle and upper rows, thereby increasing the spatial stability from the plane of the drawing is guaranteed out.
  • the luminosity of the Sofitten incandescent lamps 11 can be concentrated in a small area, whereas by pulling the scissor grids 2, 3 apart, the light emitted by the Sofitten incandescent lamps 11 is uniformly distributed over a large, elongated area.
  • Articulation points 5, 6 of a row are connected to one another by Sofitten incandescent lamps 11 or that the lamps are not arranged in the lowest articulation row 6 but in the middle or upper articulation row 5, 6 or in all articulation rows 5, 6 or are distributed as desired over these. There are no restrictions here other than practical considerations.
  • the scissor lattice can also be held vertically or at any other angle.
  • any other suitable type of fastening for. B. over supports possible.
  • a series of two or more scissor lattice lights is also conceivable.
