Definitions

  • the upper member upon which lower member the upper member is telescopically movable, that is to say, the upper one can be depressed over the lower member.
  • Thearrangement and combination of the parts is such that the fitter is enabled to eflect the fastening andthe suspension' in a very convenient manner; at the same time the above-mentioned space above the top member is no more visible, in that it is covered or closed by the top member designed according to this invention.
  • Figure 1 is a perspective representation of a top member designed according to this invention, a part of its circumferential wall being broken away in order to show the interior construction.
  • Figure 2 is a vertical section through another constructional form, and
  • Figure 3 is a sideview of still another constructional form,
  • the improved top member consists of two telescopic parts 1 and 2, of which the lower pm '(2 is intended to be alfixedto'the ri' spectlve ceiling, thatis to say,tolthe' hook screwed into a suitably located beam sameqTh'ehook (notjshownlextendsint the FOP-mem er 'througli h "tart t Ii fi .55 where there is in this part an 'eye'Skthat' iisf'to be? hung into] the hook so: as tof be coupled with the same.
  • the lower member or .part 21 is provided with a flange stand the upper member 1 is provided withfa'lower flange 7 .60
  • the upper flange 5 is formed, in the'example shown in Fig. l, by an inwardly directed anmans of a rin 'escrewed'u dnth part l, and
  • the spring '3 maybe replaced by an 'equivalent member or, members adapted tohold the part1 .in lifted position and permittingto movements'ofthe twop'arts 1 and 2 relatively to one another, as in Fig. 1.
  • bracket 13 which is rigidly connected with an eye 8. This is. the eye already mentioned in the preceding paragraphs and serving for coupling the device with the ceiling hook.
  • the bracket 13 serves at the same time as bearing for a pin 14: supporting a cord roll 9.
  • the cord. (which is indicated only by dotted lines) ex tends through bores 2 and 2 provided in the bottom 2 Attaching the top member 1, 2 to the ceiling hook is effected by depressing the part 1, downwardly over the part 2 so that the eye 8 can be hung into the hook screwed into the respective ceiling beam.
  • Fig. 2 The constructional form shown in Fig. 2 is distinguished f-romthat shown in Fig; i '1 merely by the other members by which the eye 8 is connected with the bottom 2 of the lower part.
  • theflamp is suspended by the intermediary of the current-conducting wires which extend into the top member 1, 2 through a pieceof tube 15 connected with .theflb'ottom 2 in thef'manner shown i'n'this figure
  • V the lamp is to be suspended by means of a chain 12, and that the upper end of the top member ,1, 2. isvprovided with a rosette 11 as .an'i-mprovement of the appearance of the device.-
  • a support for suspending illuminating bodies fromceilings comprising, in combination, two tubular members arranged tele- 'scopical'l'y' with respect to one another in vertical position; a compressive helical spring inserted between. said members and being 10- cated at the inner circumferential surface of the u per tubular member, and supporting the upper member elastically upon'the lower member, thus permitting movement of the upper member down 'upon and over the lower member; and means for connecting the lower member with a ceiling hook, substantially as set forth.
