Definitions

  • the invention relates to a headlight for vehicles consisting of a Housing element, in which a lighting element is arranged, with an opening, which is covered by a translucent lens that a Edge web of the lens or the housing element in at least one partially filled with an adhesive or sealant groove of the housing element or the lens is arranged.
  • the invention further relates to a method for fastening a translucent Cover plate on a housing element of a lamp, in particular a vehicle headlight, with a free edge web of the lens or the housing element is inserted into a groove that the groove before or after inserting the edge web with a sealant or adhesive is at least partially filled and that during a curing period of the Edge web is set in the groove.
  • a headlight for vehicles in which a translucent lens on a housing or support element is attached in that a pin-shaped locking means transverse to the direction of assembly the lens through the edges of the End plate or the housing element is driven.
  • the free one The edge of the cover plate is located while the locking means is being driven in preferably in one with a sealant or adhesive filled groove of the housing element.
  • a disadvantage of the known method is that for the predetermined positioning of the edge of the lens an additional one in the groove when the locking means is driven in Work step is required. Furthermore, additional measures, such as Preheating etc. required to drive the pin-shaped Locking agent is guaranteed.
  • a headlight for vehicles in which an edge web of a lens in a groove filled with an adhesive a housing element is used. So that the edge web for curing of the adhesive remains in a predetermined position, the circumferential Edge of the housing element on the inside oriented spring elements press the edge web inwards.
  • the edge web has a bulbous end on that is offset laterally from the edge web, so that the end of the edge web is positioned approximately in the middle of the adhesive bed.
  • a disadvantage of the known Headlight is that the spring element is visible from the outside. Further the spring element acts only in one direction, so that further measures are necessary to enable a central positioning of the edge web.
  • the object of the present invention is a headlight for vehicles and a method for attaching a translucent lens to specify on a housing element of a lamp, so that simple and a safe way of centering an edge web of the cover lens or the housing element is guaranteed without the agent for positioning from the outside is recognizable.
  • the headlight is in connection with the generic term of patent claim 1, characterized in that the edge web Has positioning aid element that the edge web in an unchangeable Holds position within the groove.
  • the particular advantage of the headlight according to the invention is that that an edge web of the lens or the housing element Training of the same with a positioning aid element automatically in a groove positioned and during the curing time of a sealant or adhesive is immovably stored in the same.
  • the edge webs and the walls of the groove can be structurally simple just be trained.
  • the shape of the edge web is determined by the positioning aid set that by pushing the same force or is positively connected to the edge web.
  • the positioning aid element formed in brackets and demonstrates on an inside Internal cutting elements that protrude when the positioning aid element is pushed open be driven into the side of the edge web. In this way there is a firm connection between the positioning aid element and the edge bridge.
  • the positioning aid element on an outside at least two opposite, outside protruding wing-like spring elements, which change when the Nest the edge web into the groove against the side walls of the groove and a central one Allow storage of the edge web in the groove, with a return movement is counteracted from the mounting position.
  • the spring elements protrude against the Assembly direction at an acute angle from the edge web, so that a ensures safe positioning of the edge web in the assembly position is.
  • the spring elements and / or the Cutting elements in pairs symmetrically to a central plane of the Edge web arranged. In this way, a clear position of the positioning aid element relative to the edge webs on the one hand and to the groove on the other hand allows.
  • the advantage of the method according to the invention is in particular that only through the formation of the positioning aid element a predetermined Relative position of the edge web is achieved in a groove.
  • Both the edge bridge as well as the groove can be simple geometric. Larger too Groove widths can be compensated for by the positioning aid element. On this way, a central storage of the edge web is always independent of the width of the groove or the edge web are guaranteed.
  • the positioning aid element is advantageously clamped onto the edge web.
  • the clamping can be done by cutting a cutting element, by latching or by the positioning aid element bracketed to form an inward-pointing mechanical Voltage is executed.
  • the edge web inserted in the groove by clamping external spring elements. Because the positioning aid element made of a harder material exists as the groove or the edge web, an undesirable automatic Prevents moving back from the moniter position.
  • a vehicle headlight 1 as can be seen from FIG. 1, essentially exists from a pot-shaped housing 2, in which, for example, a not shown Light source and a reflector is arranged, and one of the opening the cover plate 3 covering the housing 2.
  • the housing 2 has a encircling housing element 4, which as a groove 5 with upright side walls 6 and a base surface 7 connecting the same is provided.
  • the housing element 4 can also be designed as a support element on which the lens 3 is attachable.
  • the support element is on in this case an outer edge region of a body of the vehicle.
  • the lens 3 has a peripheral edge web 8, which is essentially is flat and spaced its longitudinal surfaces in the groove 5 can be used. So that a correct, central positioning of the Edge web 8 are positioned in the groove 5 filled with an adhesive 16 can, is a positioning aid element 9 according to a first embodiment 3 to 5 provided that at a certain distance the edge web 8 is applied.
  • the positioning aid element 9 is essentially formed in brackets and essentially has two legs 10 on, which are connected to each other via a head surface 11.
  • the head surface 11 extends perpendicular to a central plane 12 of the positioning aid element 9 or to the extension of the edge web 8.
  • the legs 10 are bat-wing-like trained, see Figure 4.
  • the cutting elements 14 are in pairs arranged symmetrically to the central plane 12 and extend in one middle region of the legs 10.
  • wing-like spring elements 15 projecting outwards close each on.
  • the spring elements 15 each extend in a corner region of the Leg 10 and cause the edge web 8 non-positively and centrally in the Nut 5 is held.
  • the spring elements 15 each press against the side walls 6 of the groove 5. Because the spring elements 15 in oriented at an acute angle against the direction of movement of the edge web 8 are, an undesired moving back of the edge web 8 from the Groove 5 prevented.
  • the positioning aid element 9 is in the assembly direction 13 pushed onto the edge web 8 until the top surface 11 of the Positioning aid element 9 on the free narrow side of the edge web 8 to the system comes. Unwanted loosening of the positioning aid element 9 will by barb-like cutting of the cutting elements 14 in the Edge web 8 prevented.
  • the groove 5 is preferably already provided with a sealant or filled with adhesive.
  • the field elements 15 press during the insertion against the side walls 6 of the groove 5, so that specified in the later Mounting position a clear positioning of the edge web 8 in the groove 5th can be maintained.
  • FIGS. 6 to 8 show a second embodiment of a positioning aid element 20 is shown, in the area near a head surface 21 spring elements 22 projecting outwards are arranged. That too Positioning aid element 20 in the form of a clamp has the same position with the preceding positioning aid element 9 opposite legs 23, but at their free ends in pairs in corner areas arranged triangular cutting elements 24 are formed. The difference to the previous embodiment allows the positioning aid 20 that the adhesive bed or groove provided in the groove 5 5 can have a smaller depth overall. For this purpose, the Spring elements 22 are arranged in an area close to the head surface 21. However, the prerequisite for using the positioning aid element 20 is that the edge web 8 has a greater length than that of the positioning aid element 9 associated edge web 8.
  • the adhesive or sealant can also be used with a Positioning aid element 9 or 20 provided edge web 8 in the groove 5 become. It is essential that through the formation of the positioning aid element 9, 20 a clear and reliable relative position of the edge web 8 in the groove 5 ensures at least during the curing time of the adhesive is.
  • the positioning aid elements 9, 20 each consist of a sheet metal material.
  • the housing elements and the edge webs each consist of one Plastic material, preferably made of a thermoplastic.
  • the wing-like spring elements 15, 22 are preferably as resilient Cutting elements formed.
