Definitions

  • the present invention relates to a device for the sealed closure of the body of a lamp and to a lamp provided with said device.
  • closing members are formed by means of bodies of varying shapes which are mechanically retained on the lamp body by hook parts which are resiliently deformable in order to ensure a force for holding together the two parts.
  • these closing means nevertheless have certain drawbacks in that the separate distributed arrangement of the hooks results in reduced gripping of the parts of the closing member which are furthest away from the said hooks, resulting in the need to provide for a greater resistive force of the hooks in order to compensate for the loss of tensile force at points situated further away; this need to provide for greater resilient forces needed to ensure an adequate grip along the entire length of the closing body results, however, in a high likelihood of breakage of the parts in direct contact with the hooks at the mounting points where the latter act.
  • the need to provide greater retaining forces makes opening of the hooks more difficult, in particular in the case of ceiling lamps where the operations are performed standing on a ladder.
  • the technical problem which is posed, therefore, is to provide a device for closing the body of a lamp which is able to ensure an optimum seal against the infiltration of condensation, moisture or the like from the outside to the inside of the body and a simultaneous reduction in the forces needed to obtain such a hermetically sealed closure.
  • this device should have small dimensions, be simple and inexpensive to produce and assemble and be able to be easily used also by non-expert users, being moreover such that it does not interfere with the basic form of the lamp so as not to alter the aesthetic appearance thereof, creating a discontinuity in the extension of the surfaces which can be visually perceived by the user.
  • a sealed closing device for lamps comprising at least one lamp body and a glass element, comprising a pair of covers extending continuously in the longitudinal direction, along the two opposite sides of the lamp body, and concealingly housed inside a respective seat formed along the longitudinal sides of the lamp body, there being envisaged resilient means for recalling each cover against said lamp body.
  • the lamp according to the present invention comprises a body 10, which is elongated in the longitudinal direction X-X and which has, arranged inside it, the technical/functional and circuit components which are necessary for operation thereof and which, being conventional per se, will not be described in detail; a flat glass element 11 for closing and protecting the lamps is moreover mounted on the body 10, being hinged therewith in the example shown in the figure; the glass 11 may pass from a position where it closes the lamp, substantially parallel to the longitudinal direction X-X ( Fig. 1 ), into a position for opening the lamp ( Fig. 5 ) rotated downwards through a suitable obtuse angle for allowing access to the inside of the lamp body.
  • the member 30 for sealed closure and retention of the glass 11 comprises a continuous profiled cover 31 extending substantially along the whole length of the body 10 of the lamp and being shaped substantially in the form of a C, the bottom flange 32 of which is designed to form a base for supporting and retaining the glass 11 and the top flange 33 of which has a recess 33a designed to allow insertion of the user's finger tips, as well as an end projection 33b which is designed to co-operate with a corresponding seat 13 of the body 10 so as to cause locking in position of the said cover 31.
  • the cover 31 has a hollow seat 31a facing inwards and designed to form the female thread of a screw 41a for fixing to the cover 31 a first bracket 41 supporting the first end of a spring 40, the other end of which is attached to a second bracket 42 fastened to the lamp body 10 by means of a corresponding screw 42a.
  • the bottom flange 32 has a tooth 32c designed to interfere in the transverse direction Y-Y with a corresponding folded end flange 42c of the second bracket 42.
  • the closing member according to the invention it is also possible to achieve uniform distribution of the retaining loads along the longitudinal surfaces, thus reducing drastically the possibility of localised breakage or cracking of the glass; moreover it has compact dimensions, is simple and inexpensive to produce and assemble and can be easily used, in safe conditions, also by non-expert users and is such that it does not interfere with the basic form of the lamp, being incorporated in its profile without altering the aesthetic appearance thereof and without creating discontinuity in the extension of the surfaces which can be visually perceived by the user.
  • the opening/closing operation is performed without the need for particular force, thus ensuring more rapid and safer operation by the user.
