Definitions

the present invention relates to a reflector for vehicles.
the present invention relates to a reflector for vehicles, of the type comprising a forwardly open reflecting body having a rear axial hole, a lamp mounted in the axial hole and having an intermediate flange, an annular socket connected to the rear end of the reflecting body and comprising a collar co-axial with the axial hole and co-operating with the said flange, and resilient fixing means associated with the collar and cooperating with the flange to fix the lamp axially, in a releasable manner, with respect to the reflecting body, the resilient fixing means including resilient thrust means co-operating with the said flange and means for engaging the resilient thrust means to the collar.
the first known type of resilient thrust means comprise a leaf spring pivoted at one of its ends on to the said collar and rotatable with respect to the collar itself between an open position and a closed operative position. When disposed in its closed operative position the leaf spring is engaged in a releasable manner at its second end, to related engagement means associated with a portion of the collar diametrically opposite that hingedly coupled to the first end of the spring itself.
the second known type of said resilient thrust means comprise a resilient ring deformable in an axial sense which is inserted into the interior of the collar and in contact with the flange of the lamp, which has radial projections which, by means of rotation of the ring itself, engage in bayonet fashion with respective engagement means associated with the collar thereby axially fixing the lamp on to the rear socket of the reflector.
a reflector for vehicles of the type comprising a forwardly open reflecting body and having a rear hole, a lamp mounted in the said hole and having an intermediate flange, an annular socket connected to the rear end of the reflecting body and including a collar co-axial with the said hole and co-operating with the said flange, and resilient fixing means associated with the collar and co- operating with the flange to fix the lamp axially, in a releasable manner, with respect to the reflecting body, the resilient fixing means, including resilient thrust means co-operating with the said flange and means for engaging the said resilient thrust means to the collar, characterised by the fact that the said engagement means comprise a pair of identical engagement brackets coupled to diametrically opposite portions of the collar; each bracket extending in a direction substantially parallel to an axis of the said hole, and having at least one associated lateral slot extending transversely of the said axis; each slot communicating with the outside through a respective opening formed in the said collar and including an inlet
the said resilient thrust means comprise a leaf spring in turn comprising at least one curved arm a first end section of which engages rotatably in the said cavity to provide the hinged coupling between the leaf spring itself and the collar, and a second end section of which is coupled in a releasable manner to the second of the said brackets and engages the said hollow terminal portion of the associated said slot.
the said resilient thrust means are coupled to the said collar by means of a bayonet coupling, and comprise an annular body resiliently deformable in an axial sense and disposed within the said collar and in contact with a rear surface of the said flange, and two projections extending radially out from the annular body and through an associated said slot; each projection being coupled to the associated slot by means of a respective said bayonet coupling.
the reference numeral 1 indicates a reflector for vehicles, comprising a reflecting body 2 of generally parabolic form which has an optical axis 3, and is provided with a rear axial hole 4 to allow passage for a lamp 5 disposed on the optical axis 3 and having an intermediate flange 6 for coupling to the reflecting body 2.
the reflector 1 further includes an annular rear socket 7 which is preferably made of moulded plastics material and comprises, in turn, an annular plate 8 limited at the front by a parabolic surface 9, which is coupled to a portion of the reflecting body 2 surrounding the hole 4.
the socket 7 further includes a generally cylindrical collar 10 co-axial with the axis 3.
the collar 10 projects rearwardly from a rear surface of the plate 8 and has at its front end an internal flange 11.
the collar 10 is rearwardly limited by an edge 12 having a plurality of axial reference cavities 13 for receiving projections 14 extending radially outwardly from the flange 6, and four further axial recesses 15 defining, on the collar 10, two diametrically opposed projections 16.
Each projection 16 is engaged by a respective substantially U-shape bracket 17 which is preferably made of punched and folded sheet metal, and is force fitted on to the projection 16 itself.
the brackets 17 extend in a direction substantially parallel to the optical axis 3, are identical to one another, and each comprises two arms 18 and 19 parallel to one another, the first extending inwardly and the second outwardly of the associated projection 16 parallel to the optical axis 3, and a cross piece 20 for connecting and joining the rear ends of the arms 18 and 19.
Each of the arms 18 and 19 has, in plan, a substantially T-shape form and comprises a crosspiece 21 adjacent to the crosspiece 20, and a stem 22 extending from an intermediate portion of the associated crosspiece 21 and of width at least equal to the width of the associated projection 16.
each stem 22 merges with the outer profile of the associated crosspiece 21 forming two semi-circular seats 23.
each stem 22 of each arm 18 carries, connected to its free end, an intermediate portion of a further crosspiece 24, a portion of which is clenched to the flange 11 to prevent accidental separation of the associated bracket 17 from the associated projection 16.
the crosspiece 24 defines, together with the crosspiece 21, two slots 25 and 26 extending transversely of the optical axis 3.
the slots 25 and 26 are disposed on opposite sides of the stem 22 and define an entrance, through the respective recesses 15, to the associated seats 23 each of which constitutes a terminal portion of the associated slot 25, 26.
each arm 18 From a free end of the crosspiece 21 of each arm 18 extends a projection 27 which is substantially parallel to and faces the associated crosspiece 24, and is limited on the side facing the crosspiece 24 itself, by a cam face 18 having an intermediate cusp facing towards the crosspiece 24 and constituting a rear edge of an entrance portion 28a of the associated slot 25.
the brackets 17 constitute a part of a fixing device 29 which further includes a first or second resiliently deformable element, respectively indicated 30 and 31, each of which is coupled to the brackets 17 alternatively to the other to fix the flange 6 of the lamp 5 with the associated projections 14 in contact with the bottom of the associated recess 13.
the element 30 is constituted by a double leaf spring preferably made of metal wire bent in such a way as to define two curved arms 32 substantially parallel to one another, one end of each of which is fixedly connected to a corresponding end of the other arm 32 by means of a crosspiece 33, and an opposite end section which is folded to form a loop 34.
the crosspiece 33 is fitted in a rotatable manner, through a cavity 35 ( Figure 4) defined between the crosspiece 20 of a first of the brackets 17 and the edge 12 of the collar 10, in such a way as to form a hinge 35a coupling the element 30 to the said first bracket 17 and, therefore, to the collar 10, and to permit the element 30 itself to rotate about the axis of the crosspiece 33 between an open position (illustrated in broken outline in Figure 1) and an operative closed position, to reach which a portion of each loop 34 is inserted, by resilient deformation of the associated arm 32, into contact with the flange 6 of the lamp 5 within the slot 25 or 26 of the second of the brackets 17, and laterally displaced until it snap-engages with the associated seat 23.
the resilient element 31 comprises an annular body 36 defined by two diametrically opposite annular portions 37 ( Figure 9) joined together by two further offset annular portions 38 disposed in contact with an upper surface of the flange 6 of the lamp 5.
Each portion 37 has an associated axial projection 39 and an associated projection 40 extending radially outwardly.
the dimensions of the annular body 36 and the projections 40 are such that the annular body 36 can be fitted axially within the collar 10 carrying the projections 40 so that each engages a respective recess 15 communicating with an associated slot 25.
