Definitions

  • the reflector and the holder carrying the lens and the diaphragm are inserted into the tubular housing from the rear.
  • a rubber cap is placed on the tubular housing from behind.
  • the end of the tubular housing pointing in the light exit direction has an outward-facing flange and surrounds it in its transition area to its outer flange, the lens at a short distance.
  • the outer dimensions of the lens are adapted to a predetermined rectangular body opening.
  • the long sides of the rectangular lens run horizontally when the headlight is installed.
  • the lens is placed from the front onto the flange, which is adapted to the size and shape of the lens, and glued to it.
  • the flange of the housing rests with its edge area on the back of an annular support for the fixed or adjustable pivot points.
  • the ring-shaped carrier is screwed to a frame placed on the front of the lens by means of fastening screws, so that the ring-shaped carrier and the frame clamp the flange and the lens firmly between them.
  • the ring-shaped carrier projects above and below the rectangular flange and has in each of these two sections a fastening point on the side for a pivot point supporting the housing.
  • a pivot point is used in three of the four possible attachment points. The three pivot points form two mutually perpendicular axes about which the headlight can be pivoted.
  • the pivot points are at least in the vicinity of the plane passing through the pivot point of the optical block consisting of the housing, reflector and lens, which is at a small distance from the flange due to the relatively large weight of the lens.
  • the optical block is connected to a fixed receiving part via the fixed or adjustable pivot points. Such or similar attachment of the optical block is often common in sealed beam applications for the USA.
  • the carrier which receives the pivot points would have to, if it should not protrude beyond the outer edge of the flange, very stable with the back be connectable of the flange and have a relatively small distance from the rear of the flange so that the position of the pivot points means that the optical block is at least approximately in the state of equilibrium.
  • Such socket-like approaches can be removed from the mold by means of radially outwardly adjustable tool parts.
  • This makes it possible to design the tubular housing in such a way that it tapers conically and / or in stages in the light exit direction. With such a solution, the outer flange widens, so that the bush-like approaches and consequently their connection to the flange can be made longer.
  • the axes of the bush-like projections which are arranged on one side of the tubular housing, run parallel to one another.
  • the design of the tool is relatively simple, since fewer adjustable tool parts are required for the demolding of the housing than if the axes of the bush-like extensions are at an angle to one another.
  • This also simplifies the assembly of the carrier, since the pin-shaped fastening elements can be inserted into the socket-like approaches from one direction.
  • the bush-like attachments are formed directly or indirectly through supporting walls on the back of the flange.
  • the socket-like lugs can be arranged at any desired distance from the rear of the flange without reducing the stability of the connection between the socket-like lugs and the flange.
  • the socket-like projections which are formed directly on the rear of the flange and the walls which support the socket-like projections are formed with their side facing the tubular housing on the lateral surface of the tubular housing.
  • a further advantage is if the bush-like projections formed directly on the rear of the flange have a section adjacent to the lateral surface of the tubular housing, which section is open towards the front of the flange. As a result, even very long socket-like approaches are very easy to demold.
  • connection between the support element and the bush-like lugs has a high strength if screws, which pass through bores of the carrier receiving the pivot points, serve as pin-shaped fastening means which engage in the bush-like lugs. It is also advantageous if the pivot points can be fixed on one or more supports. In this case, it is expedient for a carrier to be arranged on the diametrically opposite sides of the flange surrounding the tubular housing and for each carrier to have two fastening points for a respective pivot point. Such a solution is not only space-saving compared to an annular carrier, but also reduces the weight of the headlight.
  • the ellipsoidal reflector (2) and the holder (5) carrying the lens (3) and the diaphragm (4) are inserted into a tubular housing (1) made of plastic. used.
  • the reflector (2) has an opening (6) at the apex, which is surrounded on the back of the reflector (2) by an annular socket (7).
  • the bulb (8) with its glass bulb is inserted through the opening (6) of the reflector (2) until it comes into contact with the outer flange surrounding the base on the face of the socket.
  • the flange (9) of the base of the incandescent lamp (8) is fixed to the socket (7) by means of a wire spring (not shown).
  • the tubular housing (1) tapers as seen in the light exit direction through a peripheral step (15) in its central section.
  • pointing lugs (16) are formed, the end faces of which serve as a contact surface for the edge region (10) of the reflector (2). Screws (17) which fix the reflector (2) on the housing (1) engage in holes in the lugs (16).
  • a rubber cap (18) is placed on the back of the tubular housing (1).
  • an outwardly directed peripheral flange (19) is molded onto the tubular housing (1).
  • the tubular housing (1) surrounds the lens in its transition region (20) to the outer flange (19) at a small distance.
  • the flange (19) is of rectangular design and has a circumferential groove (21) on the front side at its edge area, into which the lens (22) covering the flange (19) and the lens (3) is inserted and fixed in this by gluing is.
  • the narrow sides (23) of the rectangular flange (19) run vertically. Between the narrow sides (23) and the tubular housing (1), four socket-like projections (24) and (25) are molded onto the rear of the flange (19).
  • the axes of the bush-like lugs (24 and 25) run horizontally and parallel to the main surface of the flange (19).
  • an opening is made in the center, into which the socket (27) for parking lights is inserted like a bayonet.
  • the opening for the socket can also be made in the other side of the flange (19).
  • the four bush-like lugs (24 and 25) are each arranged symmetrically to the horizontal central plane (28) of the headlamp.
  • the two bush-like lugs (24), which are at a smaller distance from the center plane (28) of the headlamp, are formed directly on the back of the flange (19) and extend from the narrow side (23) of the rectangular flange (19) to the outer surface of the tubular one Housing (1). So that these relatively long bush-like projections (24) can be easily removed from the mold, their sections (29) adjoining the lateral surface of the tubular housing are open towards the front of the flange.
  • a bracket (31) which is made of sheet metal and has a Z-shaped cross section, is formed on the four lugs (24 and 25) by means of fastening screws (32 ), which pass through bores in the free end sections (33) and (34) of the Z-shape and engage in the bush-like projections (24 and 25).
  • the two mounting brackets have a recess (35) opening in the middle of the lateral surface of the tubular housing (1), through which the socket (27) for parking lights inserted into the opening of the flange (19) passes.
  • Openings are made in the Z-shaped mounting brackets on both sides of the recess (35) in the central section of the Z-shape, which act as mounting points serve for the pivot points (36) of the headlamp.
  • the pivot points (36) are formed by plastic parts which are inserted into the openings in the fastening bracket and in which a spherical shell is inserted.
  • the ball of an adjusting element connected to a fixed receiving part or of a stationary element can be inserted into these spherical shells in a self-locking manner (not shown in the drawing).
  • the pivot points form two axes (37 and 38) perpendicular to one another, about which the headlight can be pivoted.
