Abstract
Description
- The present invention relates to a lamp-holder for vehicle headlights.
- In particular, the present invention relates to a lamp-holder capable of being fitted through a rear aperture in a reflector of a headlight to keep in position, on the said reflector, a conventional halogen lamp, in other words a lamp comprising a bulb, a socket and an intermediate flange interposed between them, of generally circular shape and provided with a lateral cut-out and axial centring pins, designed to be received in and bear on a supporting seat of the lamp-holder provided with reference holes for the centring pins.
- Known lamp-holders of the type mentioned above have the disadvantage of generally having projections in the form of springs or of orientating teeth or pins, which form part of the lamp-holder or the lamp, and which easily catch, when replacing the lamp, on other projections of the headlight or of the lamp-holder elements designed to be fixed securely to the headlight reflector. This situation may cause incorrect positioning of the lamp and, ultimately, possible distortion of the projecting elements (which are usually formed from thin sheet) with consequent difficulties in the insertion and removal of the lamp.
- The object of the invention is to provide a lamp-holder of the type described above, which is capable of facilitating the fitting of a corresponding lamp in its correct position, and, in particular, the replacement of the said lamp in cases where the headlight is disposed, as is frequently the case, in a position where access is difficult, while simultaneously reducing to a minimum the risks of catching on any projecting elements of the lamp-holder and/or of the lamp.
- On the basis of the present invention, a lamp-holder for vehicle headlight lamps is produced, the lamp comprising a bulb, a socket and a flange disposed between the bulb and the socket and provided with axial centring pins, the lamp-holder being characterised in that it comprises a cup which may be housed securely in a collar of a reflector of the headlight and provided with a through aperture for the passage of the lamp bulb, a frame element supporting the lamp in such a way that it may be released, and a bayonet connection by means of which the frame element is inserted into and connected to the cup in such a way that it may be released; the frame element comprising a transverse plate which is disposed to face the cup and through an aperture in which the lamp bulb is made to pass, the said plate having a first face, which is completely flat and free of projections, facing the cup and capable of interacting with an end wall of the cup by bearing on it, and a second face, opposite the first, capable of receiving the flange of the lamp to bear on it and provided with recesses to receive the said axial centring pins of the flange; the lamp-holder further comprising an elastic pressure element to secure the flange of the lamp by pressure, in such a way that it may be released, against the second face of the plate.
- To enable the invention to be more clearly understood, a non-restrictive description of a preferred embodiment of the invention will now be given, with reference to the figures of the attached drawings, of which

rectilinear grip bar 17, a pair of longitudinal arms orside members bar 17, and atransverse plate 20 which joins theside members bar 17; the side members extend substantially parallel to thebar 17, but are shaped with a non-rectilinear form when seen from above (Figure 2), so that the distance between them at the position of theplate 20 is greater than in the proximity of thebar 17, where theside members - The
plate 20 is disposed to face thecup 13 and is provided with an aperture 21 (Figure 4) through which thebulb 7 of thelamp 5 is made to pass when in use (Figure 12); theaperture 21, of generally rectangular shape, has, at its edge nearer the outside of theplate 20, a flared V-shaped portion 22 delimited by opposite radialoblique edges 23 and extending to form a gap which interrupts aperimetric edge 24 of theplate 20, substantially in a position opposite a prominence orprojection 25 shaped so that it can interact with the cut-out 9 of theflange 8 of thelamp 5 by bearing on it, in a way which is known and which, for simplicity, is not illustrated. - According to the invention, the
plate 20 has afirst face 26 which faces thecup 13 and is completely flat and free of projections, and asecond face 27, opposite theface 26, which is capable of receiving theflange 8 of thelamp 5 so that it bears on it, and which is provided with thesaid projection 25 towards the inside of theframe element 14, the projection being made to project from theface 27 from theedge 24 towards theaperture 21. Theface 27 is also provided with appropriate recesses to receive thepins 10, the recesses consisting of a pair of reference throughholes 28 formed to pass completely through theplate 20 and capable of receiving thepins 10, andcorresponding guide channels 29 to facilitate the insertion of thepins 10 into theholes 28, the channels forming, on theface 27, shallow grooves which extend from theedges 23, interrupting theedge 24, to the positions of theholes 28. - With reference to Figures 1, 7, 8 and 12, the
cup 13 comprises anend wall 30 facing the reflector 1, this wall being provided with athrough aperture 31 for the passage of thebulb 7 of thelamp 5, and a substantially cylindricallateral wall 32, which extends orthogonally to theend wall 30 and is connected to the internal lateral wall of the collar 3; thecup 13 is preferably formed in one piece from pressed sheet and is fixed securely to the body 2 of the headlight 1 inside the collar 3 by means of self-tapping screws 33 (or other suitable fixing means) inserted throughcorresponding holes 34 formed so that they pass through correspondingterminal lugs 35, bent at 90 °, of thelateral wall 32. A hole for theearth connection 36 is also formed on one lug. - An
internal face 37 of thewall 30, facing theframe element 14, is provided withappropriate retaining bosses 38 for thetransverse plate 20 of theelement 14, which can thus interact with thewall 30 by bearing on it, by having itsflat face 26, which is free of projections, bearing on thebosses 38. Thelateral wall 32 is also provided with a longitudinal semi-cylindrical reference boss 40 (Figure 4), disposed radially on the inside along the whole axial extension of the wall from theend wall 30 in a predetermined angular position, this boss being capable of interacting with one of theradial edges 23 of the flaredportion 22 of the aperture 21 (the left-hand edge in Figure 12 in the present case) to guide the insertion of theelement 14, and particularly itsplate 20, into thecup 13 and, simultaneously, to guide thebulb 7 of thelamp 5 so that it is correctly inserted into theaperture 31 of thecup 13. - Finally, the
end wall 30 of thecup 13 is also provided withapertures 41, of a known type, for the attachment of a coloured filter, for example a yellow filter, which is known and which, for simplicity, is not illustrated. - The
bayonet connection 15 comprises, according to the invention, a pair of L-shaped flanges 43 (Figures 8 and 12-14) formed by partial cuts in thelateral wall 32 and coplanar with it, each of the flanges being provided with acorresponding indentation 44 on a side facing theend wall 30 of thecup 13, and a pair ofcorresponding wings 45 capable of being inserted with a bayonet fitting into theindentations 44 of theflanges 43 and extending laterally on opposite sides from theframe element 14, parallel to thetransverse plate 20 and in a position to its rear; the wings 45 (Figures 5 and 6) are formed by correspondingrounded extensions 46 ofcorresponding metal springs 47 carried by and secured to theframe element 14, being clamped to theside members - In particular, the
springs 47 are made in the form of rectangular metal plates, each carrying at one end anextension 46, disposed substantially at a right angle and on the outside of theframe 14 with respect to theside members plate 20; thesprings 47 are also provided on their longitudinal edges with two pairs of opposing wings bent at right angles, and indicated by 48 and 49 respectively, the first being formed in intermediate positions and the second at the ends opposite thewings 45. In use (Figures 1 and 12), thewings 48 on opposite sides bear on corresponding upper andlower edges 50 and 51 (Figure 3) of theside members wings 49 are clamped to theside members bar 17 on theedges side members - According to a last characteristic of the invention, the
elastic pressure element 16 designed to retain thelamp 5 securely on theframe 14 consists of a fork-shaped element (Figures 9 and 10) carried on theframe element 14 so that it is free to swing (Figure 1), being hinged to the frame element about an axis parallel to theplate 20 and shaped, as is theframe 14, in such a way that, when thelamp 5 is secured, thesocket 6 of thelamp 5 is disposed inside theframe element 14, betweencorresponding prongs 56 of the fork-shaped element 16. - In particular, the fork-
shaped element 16 is formed in one piece from pressed sheet and has itsprongs 56 shaped, in itsterminal portion 57, to form arcs of a circumference having an axis of symmetry parallel to and eccentric with respect to the axis of hinging of theelement 16. This is defined by a pair of opposing holes 58 (only one of which is visible in Figure 10) formed through corresponding opposing lug-shapedlateral extensions 59 of theelement 16; transverse pins 60 (Figures 2 and 3) carried on opposite sides of theside members frame element 14, pass freely through theholes 58. - In this way the fork-
shaped element 16 may be moved selectively between a first operating position (Figure 12) in which theprongs 56 secure theflange 8 of thelamp 5 elastically under pressure (as a result of their elasticity and the eccentricity of their curvature with respect to the axis of rotation defined by the pins 60) against theface 27 of theplate 20, and a second operating position (Figure 11) in which theprongs 56 are disposed virtually parallel to theplate 20 as a result of a rotation of theelement 16 in the direction of the arrow A, so that (because of the cam effect due to the eccentricity of their curvature with respect to the axis of rotation) it does not interact with theflange 8. - To enable it to be moved between the said first and second positions, the fork-
shaped element 16 has anactuating arm 62 disposed parallel to and below thebar 17 and provided below, on the side opposite theprongs 56, with astrip 63 partially cut to form a Faston connector for a known earth wire 64 (Figure 12); at the free end, opposite theprongs 56, theelement 16 has anextension 66 forming a grip element for the fingers of a user's hand (not illustrated) and/or for a tool. In order to facilitate grasping, thegrip element 66 is formed so that it is disposed next to a concavity 68 (Figures 1 and 3) of thebar 40, formed in the lower edge of the said bar, in a position below a suitably shapedmilled end grip 70. Similarly, to facilitate the passage of thepower supply cable 6b to thesocket 6 of thelamp 5 when in use, theframe 14 is provided with achannel 72 at the base of the bar 17 (Figures 2 and 3). - The operation of the lamp-
holder 12 is as follows. Thelamp 5 is connected to thepower supply cable 6b and then, with the fork-shaped element 16 held in the said second operating position (Figure 11), thelamp 5 is inserted into theaperture 21 and, by following thechannels 29, thepins 10 of theflange 8 are inserted into theholes 28 in theplate 20, thus correctly positioning thelamp 5, whose cut-out 9 will bear on theprominence 25. Subsequently (Figure 12), theelement 16 is rotated so that theprongs 56 press against theflange 8, securing thelamp 5 to theframe 14, theearth wire 64 is connected to thestrip 63, and, with thegrip 70 of thebar 17 grasped in the hand, the assembly consisting of theframe 14 and thelamp 5 is inserted into theaperture 31 of thecup 13 along theboss 40. Finally (Figures 13, 14), theframe 14 is rotated (arrow B) so that thewings 45 are engaged under theflanges 43 of thecup 13. During these operations, any accidental catching of the frame and lamp assembly is prevented since there are no projecting parts, except for thewings 45, which are shielded by theflat face 26 of theflange 20. To replace thelamp 5, the operations described are performed in reverse order, theelement 16 being released by pressing theextension 66.
