Definitions
- the invention relates to a headlight for vehicles and in particular the attachment of the lens to the housing, according to the preamble of claim 1 and the EP 1 637 801 ,
- the EP 1 637 801 deals with the problem of the invention, which arises in particular when large-area lenses, as they are currently required in vehicle construction, must be mounted on the housing of the headlight.
- the glass-fiber lenses had bent edges that were substantially cylindrical, though not circular, to the headlight axis and thus to the main beam direction, and it was possible to insert these edges into groove-shaped receptacles in the face of the housing and either glued or fixed by screws, clamps or the like.
- Corresponding prior art is in the DE 28 46 990 and the EP 589,189 to find.
- the lens is provided in an injection molding or a foaming with a mounting edge made of plastic, which either has a cylinder jacket-like end portion, which preferably substantially parallel to Headlight axis extends and allows the mounting in the direction of the headlight axis in a circumferential end groove of a housing part, or has an end portion having an end-side groove into which a seal against a housing part is inserted.
- this connection may be a non-releasable adhesive bond, but it may also be a releasable connection held together by means of screws, clips or other fasteners.
- the Fig. 1 shows a lens 1a, which is fixedly connected by means of injection molding or foaming along its periphery with a mounting edge 1b made of plastic, such as polyurethane, to a cover 1.
- the mounting edge 1b has an end portion 7, which has a substantially cylindrical shape, although not circular cylindrical shape and in each axial section, such as him too
- Fig. 1 shows, parallel to the light direction L, usually coincident with the headlight axis, runs. It is the course in the direction of L is not mandatory but depends on the direction during demolding during manufacture and on the direction of assembly of the headlamp, for the skilled person this is easy to adapt to the shape of the entire headlamp.
- This end portion 7 can now, as in the previous headlamps bent edge thereof, inserted into a circumferential groove 8 on the front side of a housing part 2 and there permanently, for example by an adhesive 3, for example silicone, hot melt adhesive or an adhesive based on polyurethane and be tightly connected to the housing part 2.
- an adhesive 3 for example silicone, hot melt adhesive or an adhesive based on polyurethane
- the Fig. 2 shows a variant with detachable connection between the cover plate 1 and the housing portion 2, wherein the mounting edge 1b on its end face directed to the housing has a circumferential groove 8, in which a seal 5 is inserted or glued.
- This seal 5 presses on an end face 9 of the housing section 2 and is held pressed against this end face by screws 6, which are provided at the appropriate distance from one another along the circumference of the mounting edge 1b.
- screws 6 and brackets udgl as they are known from the prior art, as mentioned above, can be used. It is also essential here that a circumferential groove is provided in an end face, and that the seal is made in the groove.
- the solution according to the invention makes the assembly of the cover 1, consisting of the glass 1 a and their mounting edge 1b as simple, safe and reliable, as was the case originally with the cup-shaped glass and avoids all the disadvantages of the prior art, although large and flat or curved flat glass sheets 1a are used.
- the size of the glass pane 1a can be kept smaller than in the case of the otherwise comparable dimensions by the design of the mounting edge 1b that comprises the pane mentioned above document with the disc-shaped adhesive edge, in which the glass had to reach to the edge, and that achieved by the molding or encapsulation or foaming high bonding strength between glass pane 1a and mounting edge 1b the extension of the entire structure in the direction of the light rays L and at a right angle to this can be kept much lower than in the prior art.
