Definitions

  • the above invention relates to a table lamp with a pivotable support arm for a lighting body.
  • Table lamps with a pivotable support arm for the lighting body are known from the prior art.
  • Table lamps of this type have the disadvantage that they are equipped with one or more swivel joints on the arm of the lighting body.
  • the support arm is connected to the basic body of the table lamp with the aid of additional components, such as screws or joints. This leads to a considerable construction effort. The assembly of such lamps is also time consuming.
  • the object of the above invention is to create a table lamp with a pivotable lighting body with which the disadvantages of the known table lamps can be avoided. Furthermore, the possibility should be created to enable a sensitive pivoting of the support arm without acting on adjusting devices for the lighting body, in order to bring it continuously into desired positions, which can be selected between two end positions, whereby the lighting body is given a stable positional arrangement in a selected operating position .
  • the object of the invention is achieved by means of a table lamp with the features according to the characterizing part of claim 1.
  • the table lamp can be manufactured with a minimum of components that are quick and easy to assemble. Between two end positions of the pivoting movement of the Low intermediate lamp positions are possible for the lighting body. These intermediate positions of the lighting body are properly defined by the provision of a counterweight, as well as by the provision of connecting bolts which endeavor to exert a downward force component on the arm of the lamp.
  • the support arm for the lighting body consists of two flat metal strips arranged in one plane. This allows great freedom in the design of the lamp according to the invention, both when using several flat bands and when using a single band.
  • the provision of peg-like components in the interior of the lamp housing, which act with the bent end of the band-shaped support arm, that is to say to a part of the support arm which is arranged in the interior of the lamp body, enables simple design of the base body, e.g. B. made of injection molded plastic.
  • the basic body is designed as a shell-like hollow body to which a lower cover plate is assigned.
  • Various electrical components are accommodated in the interior of the lamp body, such as a transformer, a switch and the associated components electrical wiring.
  • the cross-section of the support arms can be chosen as desired, it is only important that the arms are delimited by two opposite planes which are aligned parallel to the pivot axis of the bent piece of the lamp support arm.
  • FIGS. 1 and 2 Basic body of the lamp, along the line II-II of FIG. 1.
  • the lamp according to the invention is shown in FIGS. 1 and 2 with a continuous and with a broken line in the two end positions of the lighting body.
  • the lamp is identified as a whole by 1 and has a basic body 2 and an arm 3 for receiving an illuminating body 4.
  • the lighting body 4 can be equipped with any light source.
  • the arm 3 of the lighting body 4 is formed by two flat metal strips 3a, 3b arranged next to one another, whereby these Metal strips are arranged in a common plane.
  • the ends of the support arm 3 directed towards the base body 2 have a curvature, advantageously a semicircular curvature.
  • the curved end of the support arm 3 is mounted inside the base body 2 between two transversely arranged pins 5, 6.
  • the cross pins 5, 6 are arranged parallel to the imaginary axis of rotation A of the support arm 3.
  • the pins 5 and 6 rest on the opposite broad sides 3a, 3b of the metal strips 3.
  • the pins 5 and 6 are advantageously received by a holder 7 which is arranged in the basic body 2.
  • the base body 2 advantageously consists of a shell-shaped body 8 and a removable base plate 8a.
  • the base plate 8a accommodates a transformer 9 in the example shown.
  • a switch 10 is arranged, in the upper wall 11 of the housing 8 there is a slot 12 which forms a passage for the holding arm 3, that is to say for the flat metal bands 3a and 3b .
  • a counterweight is identified by 13, which is attached to the metal strips 3a and 3b.
  • the counterweight has the task of compensating for the force component exerted by the illuminating body 4 by a simple and accurate positional arrangement (positioning) of the lighting body 4 in any position between the two end positions.
  • the counterweight 13 also has the task of determining the two mentioned end positions of the swivel arm.
  • the counterweight 13 has a block-like shape and has a first stop surface 14 and a second stop surface 15.
  • the lower end position for the pivoting movement is determined by striking the surface 14 of the counterweight 13 on the pin 5.
  • the upper end position for the pivoting movement which is shown with dashed lines, is determined by striking the surface 15 of the counterweight on the inner wall of the front 8b of the housing 8, as shown in FIG. 1.
  • the pivoting movement of the support arm 3 thus takes place essentially along a circular arc piece of the arm mounted in the basic housing, pivoting movement which takes place about the axis A.
  • pivoting movement which takes place about the axis A.
  • a smooth and uniform pivoting movement of the support arm 3 thus occurs. Due to the geometric and constructive structure, it is possible to easily swivel any position Make lighting body 4 by a single handle. Due to the proposed embodiment, the support arm 3 automatically remains in the desired pivot position as soon as the action is interrupted by hand.
  • the arm 3 Due to the provision of a counterweight 13 and the holding effect of pins 5 and 6, the arm 3 remains in its desired position.
  • the free end 3c of the flat metal strips 3a, 3b is bent at an angle for safety reasons.
  • the pins 5 and 6 are attached to the holding part 7 in an advantageous manner by using suitable spring washers.
  • the object is achieved by the table lamp designed according to the invention.
  • the design requires a limited number of components and also enables simple and quick assembly of the table lamp.
  • the components described can be replaced by similar construction elements without leaving the scope of the invention.
  • the housing which was proposed as a shell-like plastic structure, can have one or two parts be trained.
  • the base plate 8a can be arranged in any way on the housing and the balance weight 13 can be provided as the only block-like structure which acts on both band-like metal bands 3a and 3b.
  • each metal strip 3a, 3b can also be provided for each metal strip 3a, 3b.
  • the holder 7 for receiving the sliding pins 5 and 6 can be arranged anywhere in the interior of the base body 8, the arm 3 can also be formed in one piece without thereby leaving the scope of protection of the invention.
  • the embodiment according to the invention enables the greatest possible freedom with regard to the design of the lamp, for example it can be possible to give the basic housing a different design. Even if two band-shaped components 3a, 3b are provided in the illustrated exemplary embodiment for supplying the electrical current (weak current) to the light source 4, the connection between these parts and the switch or the transformer, and the selection of the electrical components and cabling, can be the case to be chosen.
  • the dimensions and materials for the manufacture of the lamp can also be freely selected.
