Definitions

  • the present invention relates to a support for lamp holders, especially for halogen lamps.
  • a drawback is due to the fact that the coupling of the lamp holder to the support is not perfectly irreversible and it may involve safety risks when the illumination devices provided with such supports for lamp holders are employed.
  • a further drawback is due to the production cost of the known supports for lamp holders, which is too high with respect to the low safety level.
  • the main object of the present invention is to overcome the above drawbacks.
  • the present invention makes it possible to considerably increase the safety level, given the perfectly irreversible coupling of the lamp holder to the support. Furthermore, the present device is relatively simple to make, cost-effective and reliable even after a prolonged service life.
  • a support for lamp holders according to the present invention is made by a hollow body (1) having a substantially cylindrical shape, which is destined to receive in its cavity (10) a lamp holder (2) for halogen lamps, for example a ceramic lamp holder.
  • said body (1) is provided with a base portion (11) and a mouth (12) through which the lamp holder (2) is inserted, said base (11) being provided with a through hole (110) for the electric supply cords (3), the said hole being, at least in correspondence of the base (11), narrower with respect of the lower base (20) of the lamp holder (2), so that it is allowed the positioning of the lamp holder (2) into the cavity of the body (1), through the mouth (12), but it is avoided the passage of the lamp holder (2) through the base (11); furthermore, the body (1) is provided with two appendixes or fins (13) protruding towards the inner side of said cavity (10), the free ends (130) of said appendixes or fins being oriented towards the said base (11). Said appendixes (13) protrude from the inner side wall of the body (1), the base portion of each appendix (13) being in proximity of the mouth (12).
  • the hole for the passage of the cords (3) may be internally threaded to permit the screwing of the body (1) onto a tige (not shown in the drawings).
  • the external side wall of the body (1) may be threaded, as shown in the drawings, to allow the screwing of a locknut (not shown in the drawings) on the body (1) so as to lock thereon an object such as a lampshade or the like, in analogy with the conventional supports for lamp holders.
  • two or more appendixes (14) protrude from side of the base (11) of said body (1) facing the mouth (12), said appendix being apt to act as spacer elements to avoid the direct contact of the lamp holder (2) with the base (11).
  • the side wall of said body (1) may be provided with two openings or windows (15) for a better ventilation of the cavity (10).
  • the body (1) is advantageously made in a single element, including the appendixes (13) and the spacer elements (14), by molding of per se known plastic material (for example, PPS-RVM).
  • the lamp holder In order to couple the lamp holder with the support (1), it is sufficient to position the lamp holder coaxially with the body (1) in correspondence of the mouth (12), as shown in Fig.5A, and then push the lamp holder towards the base (11) until the ends (130) contact the step (21) of the lamp holder (2). In this way, the lamp holder is irreversibly coupled with the body (1), because it cannot pass through the base (11), from the side of the cords (3), and it cannot pass through the mouth (12) due to the presence of the appendixes (13).
  • the base portion (11) is also provided with two holes (100) which are on opposite sides with respect to the aforementioned hole (110) and may be used for fixing the body (1) to a fixed part of the illumination device to which the support is destined, with screw means (not shown in the drawings) passing through the holes (100).
  • the lamp holder (2) is of a type commonly available on the market.
