Definitions

  • the present invention relates to an anchoring device for lamp holders.
  • EP 141021 discloses a lamp holder, consisting of a one-part holder body which is formed as a plastic injection-moulded part.
  • US 2108632 discloses a lamp socket assembly with a socket enclosure of insulating material comprising an upper portion provided with a transverse opening and a lower portion cooperating with the upper portion to form a socket enclosure provided with a longitudinal opening, a nipple positionable in said transverse opening and provided with legs and an opening connecting with the longitudinal opening, a separable lamp receiving means rigidly positionable within said longitudinal opening, and means cooperating with said legs and with both portions of the enclosure for assembling the enclosure and nipple into a rigid, unitary structure.
  • the main aim of the present invention is to drastically reduce the above drawbacks.
  • a device according to the invention is easy to make, cost-effective and reliable even after a prolonged use.
  • an anchoring device for lamp-holders is constituted by a substantially annular element or ring (1) which is provided with two couples of flexibly elastic appendixes (2) diametrically opposed, that are disposed on opposite sides with respect to the symmetry axis (x-x) of the same element (1).
  • Each of said appendixes (2) forms a single body with the annular element (1) and is longitudinally developed along a direction parallel to said axis (x-x).
  • each of said appendixes (2) is shaped like a claw, with its tip (20) oriented towards the symmetry axis (x-x) of the annular element (1).
  • the two appendixes (2) protruding from a same edge (10) of the ring (1) are oriented perpendicularly to the two appendixes (2) protruding from the opposed edge of the same ring.
  • said element (1) has a radial hole (3) provided within a substantially cylindrical portion (30) thereof, said portion (30) emerging from the external surface (11) of the element (1) and being internally threaded.
  • Said hole (3) is used, as said below, for the passage of the electrical supply wires, and the internal threading of said portion (30) allows the screwing of the element (1) onto a corresponding supporting tige (not shown).
  • Said portion (30) of the element (1) is provided with a hole (31) whose axis is orthogonal to the longitudinal axis of the same portion (30), said hole (31) allowing a screw (not shown) to be screwed therein in order to prevent the rotation of the element (1) on the supporting tige when mounted.
  • each of said wings protrude, disposed on opposite sides with respect to the cylindrical appendix (30) and developed along a plane which is substantially orthogonal to the symmetry axis (x-x) of the element (1), each of said wings being provided with an orthogonal hole (33).
  • Said wings (32) serve to fix the element (1) by utilizing screws passing through the hole (33), on a bracket instead of a tige.
  • Said element (1) can be produced with a conventional moulding technique, in a electrical insulating material, for example nylon glass reinforced (type PA66RV).
  • a electrical insulating material for example nylon glass reinforced (type PA66RV).
  • the cylindrical bodies (4) shown in the drawings on the internal lateral surface of the element (1) are simply service pins which serve to allow the intervention of the extractors normally used in the moulds for producing the element (1).
  • the lamp holders (6) are connected to the element (1), in such a way that the tips (20) of the appendixes (2) are inserted in the base windows (61) of the lamp holders (6).
  • the appendixes (2) bend slightly outwardly during this step.
  • the apparatus thus obtained comprises two lamps (5) which result coaxial and opposed with respect to the element (1) . The latter is then fixed on a tige or on a bracket as previously said.
