Definitions

  • ABSTRACT The base and three elbowed sections of the lamp are rotatably and detachably secured together by a ring fixed inside the open end of one section and seated in an annular groove in the outer peripheral wall of a resisient crown fixed inside the adjacent open end of the next section.
  • a luminous device with focusing lens is secured in like manner in the outer end of the last elbowed section and air vents are provided in the various sections for the circulation of air through the sections and over the transformer mounted in the base.
  • the present invention refers to improvements applied to the manufacture of lamps, which consist in that the lamp is made up by different sections, which can be elbowed, and joinedin a revolving manner by one of their openings, which allows that each one of the sections of the body of the lamp may acquire a desired position, independent from the positions of the adjacent sections, and which sections contain a lens with advance and return motion, so that the focus of the light may be scattered or made sharp with intermediate variations, and also contain the necessary transformer so as to be able to alter the voltage.
  • FIGS. 1 and 2 are elevational views of the lamp according to the improvements, and illustrate its application on a table or on a wall.
  • FIG. 3 is a front elevation of same lamp partially sectioned, in a larger scale.
  • FIG. 4 is a sectioned side elevation of the lamp shown in FIG. 3;
  • FIG. 5 is anenlarged detailed section according to line VV of FIG. 4.
  • Thelamp of this invention is made up by several elbowed pieces or sections 1 which are rotatably joined to the adjacent sections so as to allow one section to rotate on the other.
  • the rotatable joint between adjacent sections comprises a ring 2 and a crown 3, which are placed respectively on the inside of one of the ends of the cylinder shaped sections of the lamp, and in the inside of the end part of the other adjacent cylindrical section to be coupled, the crown 3 having in one of its edges a series of resilient press fingers 4, which are arranged in a perpendicular and annular manner, said press fingers 4 having on their back part a convex ridge 5 which,when all the press fingers are in place, form a ring-like groove 5a that is disposed inwardly of the convex ridge and interrupted by separations 6 between each press finger.
  • Two adjacent cylindrical sections 1 are rotatably joined by facing the points of the press fingers 4 of one section towards the ring 2 of the other section and, by means of pressure, forcing the press finger 4 into the ring 2 and seating the ring 2 inside the groove 50.
  • the rings 2 and the crowns 3 are provided with radial tailpieces 8, 8a on the outer edge of same, which are lodged incorresponding radial grooves 9 of the interior part of the edge of the opening in which they must remain, for which purpose the back part of these radial tail pieces are also grooved, in such a manner that their grooves link in with or are seated in the projections of the grooves 9.
  • a greater fastening of the radial tailpieces 8, 8a to the grooves 9 of the interior walls of the openings of the sections 1 is desired, then, there also is a joining adhesive 10.
  • crown 3 and ring 2 respectively.
  • Improvements in the manufacture of lamps characterized by a lamp made up by several cylinder shaped sections, including a base section and elbowed sections, which are rotatably joined by coupling means to the ad:
  • said coupling means comprising a ring and a crown, which are fixed respectively on the inside of one of the ends of one of the cylinder shaped sections of the lamp, and on the inside of the opening of the other cylindrical section which is adjacent and is joined with the first; the crown, in its free edge being provided with several press fingers, arranged in an annular and perpendicular manner, said press fingers having a concave groove on their outersurface, which in a conjoint manner form an annular groove interrupted by the separation which exists between eachpress finger, the inner peripheral edge of said ring being rotatably seated in said annular groove, the top edge of the press fingers being more prominent than the concave groove thereby forming a stop piece .for the ring, whereby when a light separating traction is exerted on any of adjacent joined sections, separation will be achieved when the antagonistic action of the press fingers is surpassed.
