Definitions

  • the present invention relates to a reversible snap fixing device for a lighting apparatus to be encased in a support panel such as a false ceiling.
  • a well-known, popular system of this kind for small encased apparatuses uses at least one pair of arms elastically connected to the apparatus body and extending from it on diametrically opposed sides.
  • the arms are forced against the front flange of the apparatus body so that the elastic reaction must be overcome by turning them approximately by 180° to make them pass through the opening in the false ceiling for mounting.
  • the arms Once the apparatus has been inserted, the arms are released and they push against the inner surface of the false ceiling, whereas the front flange forces the outer surface, thus locking the apparatus in its encased position.
  • To remove the apparatus it must be pulled out, to overcome the reaction of the elastically connected arms.
  • This system is unsuitable for larger and heavier apparatuses, as the springs (which, for safety reasons, must be capable of supporting at least five times the weight of the apparatus) would require excessive pre-loading. Mounting and removal would therefore require too much effort.
  • Another system used for large encased apparatuses provides a cylindrical frame on which the apparatus body is mounted. At least two supports for flexible laminar elements are provided on the lateral surface of the frame, these elements being fixable by means of sliders moving along said supports and abutting against the inner surface of the false ceiling.
  • This is a rather expensive system and mounting is difficult and uncomfortable, as first the frame has to be inserted in its hole, then, while holding it still in its position, the flexible laminar elements must be mounted and locked with the slider and, finally, the apparatus body has to be fixed by means of a screw or similar. It should be pointed out that the use of tools, as required in this case, makes mounting even more uncomfortable, considering that the installer has to work at a certain height above the ground.
  • the flexible fastening arms can be retracted into the frame of the apparatus, allowing its insertion into the opening.
  • the use of tools is required in this case too to fix the arms, and the apparatus body must be fixed to the frame.
  • a further fastening system provides flexible arms (usually three) which extend tangentially from the apparatus body. To mount the apparatus, the arms are drawn near the apparatus body and then released, once the apparatus is inserted. This solution is actually limited for use with a false ceiling which has the thickness for which the apparatus has been designed; in addition, removal is difficult and may damage the false ceiling.
  • Another object of the invention is to provide a device of the type mentioned above, which does not impair the exterior appearance of the lighting apparatus.
  • a further object of the invention is to provide a device of the type mentioned above, which automatically fits various thicknesses of panels in which the lighting apparatus has to be encased.
  • the reversible snap fixing device comprising a first arm pivotally connected to the apparatus body near its front opening and extending from it laterally; a second arm made of a flexible material, which extends from the free end of the first arm, angled with respect to it so that its free end points towards the apparatus body.
  • the latter free end is bent substantially perpendicular with respect to the development of the second arm, on an intermediate section of which a projecting part is provided.
  • a hole is made in which the second arm is slidingly engaged, so that it can be placed in a first or mounting position wherein the first arm substantially flanks the apparatus body and the second arm extends inside said body, and a second or locking position, wherein the first arm is turned by approximately 90° with respect to the previous position and the second arm is forcibly engaged against the lighting apparatus body by means of its projecting part, thus elastically forcing the first arm against the inner surface of the panel.
  • the second arm acts as a resilient strut between the lighting apparatus body and the panel in which it is encased, the panel being therefore placed between the first arm of said device and the perimetric external flange of the apparatus itself.
  • the first arm and the second arm of the device consist of one single elongated laminar element, made of steel of suitable resiliency, bent to form substantially a "V" around an abutment block by means of which the thrust of the second arm is transferred to the panel.
  • Two radial fins 5 protrude from the external surface of body 1 near opening 2, and support a pivot 6 around which is mounted the end of a first arm 8, bent to form an eyelet 8a, of an elongated laminar steel element, generically indicated with 7, suitably flexible and substantially bent to a V-shape, to form first arm 8, which extends laterally from body 1, and a second arm 9 pointing towards body 1 and sliding in a slot 10 provided therein.
  • the free end 9a of second arm 9 is bent substantially perpendicular with respect to arm 9 itself, whereas from an intermediate point of arm 9 a tab 11, elevated with respect to the arm profile and obtained for example by shearing the latter, extends axially, substantially near the bent part 9a.
  • a substantially cylindrical block 12, abutting on the inner surface of panel 3, is placed in correspondence of the bending point of laminar element 7, this point corresponding to the ends of first arm 8 and of second arm 9.
  • the apparatus body 1 is introduced in hole 4 of panel 3, while the elongated laminar element 7, as shown in Figure 5, is arranged so that its first arm 8 flanks the external surface of body 1 and second arm 9 is completely housed inside body 1.
  • the perimetric flange la of body 1 is held against the external surface of panel 3, while arm 9 is simultaneously slid in slot 10, so that it gets out from body 1 until element 12 abuts on the inner surface of panel 3.
  • a force in a radial direction must then be exerted upon bent end 9a of arm 9, the thrust being transferred to panel 3 through pressing element 12, thus causing arm 9 to bow progressively as shown in figure 1.
  • the bent end 9a is kept pushed until tab 11 is completely out of slot 10, being tripped and abutting against the external surface of body 1, whereas arm 9 abuts on the edge bordering slot 10. This operation must be repeated on the other devices the apparatus is provided with, until it is completely fastened. In this way, two opposing forces act on panel 3, one exerted by the perimetric flange la of body 1 on its external surface and the other exerted by the pressing element 12 on its internal surface, thus the apparatus being firmly fastened to panel 3.
  • the surface of the spotlight can be provided with a special, substantially concealed seating 13 in which the bent end 9a is housed, once the apparatus has been fixed, preventing that the bent end 9a impairs the apparatus appearance.
  • this end is embodied in a small plastic block 14 with the same shape of seat 13 which is, therefore, practically filled up to the level of the spotlight surface when tab 11 is engaged with the external surface of body 1.
  • the fixing device As the fixing device according to this invention is pivotally connected with the lighting apparatus body, it automatically fits the thickness of the panel within a relatively wide range and does not require specific models for each thickness or group of thicknesses.
