Definitions

  • the present invention relates to a reversible fixing device for a lighting apparatus to be encased in a support panel such as a false ceiling.
  • a reversible fixing device for a lighting apparatus to be encased in a support panel, comprising a first arm, pivotally connected to the body of the apparatus near the front opening thereof and extending sideways from such opening.
  • a second arm made of a flexible material extends from the free end of the first arm and is angled with respect thereto so that its free end points towards the body of the apparatus. The latter free end of the second arm is bent substantially at right angle in relation to the lengthwise direction of such arm.
  • a protrusion is formed on an intermediate portion of the second arm.
  • a slit is formed in the body of the apparatus, for slidable engagement with the second arm, which then can be displaced between a fitting-up position and a fixing position. More precisely, in the fitting-up position the first arm substantially flanks the body of the apparatus and the second arm extends inside said body. Conversely, in the fixing position the first arm is pivoted by about 90° with respect to the previous position and the second arm forcibly engages, thanks to its protrusion, against the body of the lighting apparatus, so that the fist arm is elastically forced against the inner face of the panel. In this way the second arm acts as a flexible strut between the body of the lighting apparatus and the panel in which it is encased. Therefore, such panel remains between the first arm of the device and the external peripheral flange of the apparatus.
  • the object of the present invention is to provide, by means of an originally structured device, a further advantageous solution as far as the above raised issues are concerned.
  • Another particular object of the invention is to provide a device of the above mentioned kind in which, during the fitting up operation, no harm can be caused to the hands of the operator as a result of the abrupt release of elastic members.
  • a further particular object of the present invention is to provide a device of the above mentioned kind by means of which the fixing force exerted on the lighting apparatus can be distributed all along the connection with the false ceiling in a relatively uniform way.
  • the reversible fixing device for a lighting apparatus to be encased in a support panel such as a false ceiling characterised in that it comprises: a frame fit to be encased within a hole of the panel, defining an opening for housing the apparatus and comprising a peripheral lip extending outwards, for abutting against the outer face of the panel; sliders placed on the outside of said frame, axially slidable between a fixing position, adjacent to the lip, and a fitting-up position; means for operating the sliders from said fitting-up position to said fixing position; first elastic means co-operating between the sliders and the lip of the frame, for hindering the sliding of the sliders towards said fixing position and radially deformable owing to said sliding, whereby, when the frame is encased within the hole the first elastic means force the lip against the panel; and stop means associated to the frame, fit for engagement with the sliders in order to stop them in the fixing position.
  • the stop means comprise second elastic means for assuring a snap engagement with said sliders.
  • the first and second elastic means consist in flat springs axially co-operating between the sliders and the frame.
  • the operation means comprise ridges and/or rims protruding from the sliders.
  • reference numeral 1 indicates a frame defining an inner opening 2 for housing the body of a lighting apparatus to be encased, of a known type, not shown.
  • Frame 1 is fit to be placed within a hole, formed in a support panel, with a contour corresponding to the outer peripheral one of frame 1 itself.
  • the support panel for instance forming a false ceiling, is not shown either.
  • frame 1 comprises a generally tubular member 3, cylindrical in the depicted embodiment, defining opening 2.
  • a lip 4 extends radially from an edge of member 3, so as to be fit for abutment against the outside of the support panel, as will be explained hereinafter.
  • Two wings 6 axially extend from the other edge of tubular member 3, on diametrically opposite positions. Respective windows 6 are formed within wings 5.
  • each wing 5 externally forms a support guide for slider, by means of a couple of axial ribs 7.
  • each slider consists of a substantially quadrilateral plate 8. Only one plate 8 is represented in the figures for the sake of clarity; the following description will refer to such plate 8, and to the relevant wing 5, the diametrically opposite part of frame 1 being shaped likewise.
  • Plate 8 is slidable between two run end positions established by the abutment of two screws 9, fixed to the plate, against the longitudinal ends of respective slots 10, axially formed in tubular member 3 between lip 4 and window 6 for slidably receiving screws 9 themselves.
  • the side of plate 8 adjacent to lip 4 also provides an outwards protruding ridge 11.
  • a substantially quadrilateral passage 12 is also formed in plate 8, so that it remains over window 6 of wing 5 as plate 8 slides between the run end positions.
  • a rim 13 extends inwards, through window 6 of wing 5, from the side of passage 12 which is adjacent to the ridge 11 of plate 8. Such side is outlined so as to form a central notch, in correspondence to which rim 13 defines a U-shaped seat 14 comprising a bottom portion 14a. An aperture 15 is formed in said bottom portion 14a, adjacently to the junction with wing 5.
  • each spring 16 an end is connected to the outside of plate 8 - e. g. via rivets 22 - near the side which is opposite to that providing ridge 11, while the other end is urged against lip 4, whereby the maximum extension of springs 16 substantially correspond to the fitting-up position of plate 8.
  • a further flat spring 17 axially extends from the inside of tubular member 3, in correspondence to wing 5.
  • a junction end of such spring is fixed - e. g. by means of a screw 23 - in an intermediate point between slots 10.
  • the other end, which is free, extends towards window 6 of wing 5 and is bent inwards, so as to define a tooth 18, fit for introduction in aperture 15 of seat 14 and for snap engagement with bottom 14a. Thanks to such engagement, the sliding of plate 8 can be stopped when the latter is in the fixing position.
  • An outwards flexion of stop spring 17, preceding its snap engagement motion, is operated by bottom 14a, by thrusting an inclined portion 18a of tooth 18.
  • the flexion is allowed by a notch 19, centrally provided by the side of window 6 that is adjacent to lip 4.
  • the device according to the invention operates in the following way.
  • Frame 1 in advance connected to the body of the lighting apparatus, is partially inserted the hole of the false ceiling, the plates 8 being in the fitting-up position (see figure 3), until ridges 11 abut against on the ceiling itself.
  • the device can be removed from its location by radially pushing inclined portions 18a of teeth 18 of stop springs 17, thus triggering the release thereof from the bottoms 14a of the corresponding seats 14. Also this step may require the preliminary removal of the reflector of the lighting apparatus. plates 8, urged by the respective springs 16, move back to the fitting-up position. Since springs 16 are no longer deformed, it is possible to pull out frame 1 from the hole of the false ceiling.
  • the fitting-up procedure can be carried out very easily and rapidly.
  • Such procedure consists of a simple compressive operation, which can be accomplished with a relatively low effort and with a natural and easy movement of the hands.
  • the removal procedure is also accomplished with a simple movement, which requires a very low effort and above all does not bring about dangers for the hands of the operator, because the extension of springs 16 and the consequent abrupt motion of plates 8 do not concern the area in which said hands are at work.
  • the design parameters of the device shall be adjusted, as obvious to the skilled person.
  • a configuration like that of the depicted example makes in any case the device suitable for panels from 1 mm to 30 mm wide.
