Description

Field of the invention

[0001] The invention relates to a headlight for a bicycle and a bicycle equipped with the headlight. Furthermore, the invention relates to a set comprising a headlight for a bicycle and at least two different mounts for attaching the headlight to the bicycle. Background of the invention

[0002] Bicycle headlights, as is common practice, can be mounted at various points on the bike. For example, some headlights include a bracket with a clamp that allows the headlight to be attached to the handlebar. These headlights are usually battery-powered.

[0003] There are also headlights that are attached, for example, to a frame part or the front mudguard.

[0004] Depending on the mounting system used, the bracket is attached to a different location on the headlight housing. For example, the product range from the manufacturer Supernova® is a good example. This manufacturer offers headlights with a bracket attached to the side with a clamp for the handlebar, as well as other models where the bracket is attached to the bottom or top of the headlight housing for attaching it to the frame.

[0005] This comes with the disadvantage that, depending on the mount, the headlight housing has a different mounting point. Therefore, different headlight housings must be provided depending on the mount.

[0006] The document FR 811 978 A shows a headlight for a bicycle. Object of the invention

[0007] The invention is based on the object of providing a headlight for a bicycle which can be used flexibly in conjunction with various holders. Summary of the invention

[0008] The object of the invention is achieved by a headlight according to claim 1 and by a bicycle equipped with the headlight.

[0009] Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

[0010] The invention relates to a headlight for a bicycle. A bicycle, as defined by the invention, also includes a bicycle with an electric auxiliary drive (e-bike, pedelec) as well as a multi-track pedal-driven vehicle.

[0011] The headlight can be designed either as a battery-powered headlight or as a headlight that can be connected to the bicycle's power supply.

[0012] The headlight comprises a housing with at least two attachment points on the side of the housing. In particular, at least one lateral attachment point, i.e., on the right or left, as well as an upper and / or lower attachment point can be provided.

[0013] The mounting points are used for connecting to a holder. The mounting points can be designed, in particular, as internal threads. Preferably, the internal thread is designed as a blind hole. This prevents moisture from penetrating the housing.

[0014] According to the invention, the housing comprises a rotatable ring which, in one position, exposes a first fastening point and conceals a second fastening point.

[0015] For this purpose, the ring can in particular comprise a through hole.

[0016] By turning the ring, one of the attachment points becomes accessible, to which the holder can then be attached.

[0017] The unused attachment point(s) are covered by the ring and thus protected from the elements.

[0018] Furthermore, the ring is preferably fixed to a main housing of the headlight by attaching the holder.

[0019] The housing can, in particular, have at least three fastening points. These can, in particular, be arranged at 90° to each other around the circumference of the housing.

[0020] The headlight can, in particular, have an upper attachment point, a lower attachment point, and at least one lateral attachment point. "Upper," "lower," and "lateral" within the meaning of the invention each refer to the intended installation position.

[0021] The mounting hole can be designed as an elongated hole, particularly a longitudinally extending elongated hole. This compensates for shape tolerances and facilitates installation.

[0022] In one embodiment of the invention, the ring extends around a main housing and adjoins a front housing section of the main housing designed as a collar.

[0023] The main housing acts as a front stop for the ring.

[0024] Preferably, the ring should be flush with the collar of the main housing. This avoids a step between the ring and the collar of the main housing.

[0025] The ring preferably completely encloses the side wall of the main housing with the exception of the collar.

[0026] The main housing can have a conical rear section that protrudes from the ring. This section can, in particular, include cooling fins for the headlight. According to one embodiment of the invention, cooling fins distributed around the rear circumference protrude beneath the ring. This allows air to cool the heat sink even beneath the ring.

[0027] Furthermore, according to one embodiment of the invention, a vapor-permeable membrane is inserted into the main housing of the headlight, which is arranged under the ring.

[0028] This allows water vapor to escape from the headlight. At the same time, the ring protects the vapor-permeable membrane from the elements. In particular, it prevents the vapor-permeable membrane from becoming wet with water.

[0029] In conjunction with cooling fins extending beneath the ring, water vapor can escape between the cooling fins.

[0030] The headlight may comprise at least one holder which is attached to one of the attachment points.

[0031] The holder may in particular comprise a clamp for attachment to the handlebar, a section connectable to the handlebar clamp or a screw-on tab.

[0032] Depending on the type of holder used, it can be attached to a different mounting point.

[0033] The invention further relates to a set with a headlight for a bicycle as described above.

[0034] The set comprises a headlight with a housing which comprises at least one side attachment point and a lower and / or upper attachment point.

[0035] The set also includes a first holder that can be attached to the side attachment point and a second holder that can be attached to the lower and / or upper attachment point.

[0036] The invention further relates to a bicycle equipped with the headlight described above. The headlight can be attached, for example, to the handlebar by means of a clamp, to the handlebar clamp by means of a specially designed holder, or to a frame component or mudguard by means of a mounting bracket.

Detailed description of the drawings

[0038] Fig. 1 shows a perspective view of a headlight 1.

[0039] The housing of the headlight comprises a main housing 10, which is surrounded by a rotatable ring 20, and a front part 30.

[0040] Furthermore, the headlight 1 comprises the light exit element 40 at the front, which can comprise a lens.

[0041] The rotatable ring 20 is placed on the main housing 10 from behind and is flush with a collar 12 of the main housing.

[0042] A reflector 50 is attached to the housing of the headlight 1 at the bottom.

[0043] The rotatable ring 20 comprises a through hole 21, which is designed as a longitudinally extending elongated hole.

[0044] In this illustration, the ring 20 is adjusted so that a lateral thread 11a is accessible as a lateral fastening point.

[0045] Fig. 2 is a perspective view of the headlight 1.

[0046] The ring 20 is now adjusted such that the through hole exposes an upper thread 11b as a fastening point.

[0047] Fig. 3 shows the headlight in a perspective view, whereby the ring 20 is now adjusted so that the through hole 21 exposes a lower thread 11c as a fastening point.

[0048] The attachment point is located behind reflector 50.

[0049] Fig. Figure 4 is an exploded view of the headlight components.

[0050] The front part 30 of the housing comprises a conical section 32 which merges into a cylindrical section 31.

[0051] The front part 30 is designed as a ring. The front part 30 includes a thread 33 designed as an internal thread.

[0052] The front part 30 is screwed onto the thread 13 of the main housing 10 via the thread 33.

[0053] The light exit element 40 is fixed between the front part 30 and the main housing 10.

[0054] In this embodiment, the light exit element 40 comprises a lens 41 and a collar 42 adjacent to the lens 41. The collar 42 is pressed against the main housing 10 by the front part 30, while the lens 41 protrudes from the advantage 30.

[0055] In this embodiment, the collar 42 has lateral extensions 43, which serve as a form-locking element in a corresponding recess of the main housing 10.

[0056] The main housing 10 comprises the thread 13 designed as an external thread on the front side. A collar 12 is adjacent to this.

[0057] For assembly, the light exit element 40 is inserted into the main housing 10. The front part 30 is then screwed onto the thread 13 and thus fixes the light exit element 40 by enclosing the collar 42 between the front part 30 and the main housing 10.

[0058] Adjacent to the thread 13, the main housing 10 has a cylindrical area in which the threads 11a - 11c serving as fastening points are located.

[0059] On one side, the main housing 10 has a through hole 16 instead of a thread. A vapor-permeable membrane (not shown) is inserted into the through hole 16, through which water vapor can escape from the housing of the headlight.

[0060] The main housing 10 includes cooling fins 15 on the rear.

[0061] In the area of ​​the cooling fins 15, the main housing 10 merges into a conical section 14.

[0062] The ring 20 placed on the main housing 10 also extends over the through hole 16 for the vapor-permeable membrane when assembled.

[0063] The reflector 50 is attached to the main housing 10 by means of the screw 52.

[0064] In this embodiment, the reflector 50 is attached to the collar 12. A projection 51, which serves as an anti-twist device, engages in a corresponding recess in the collar 12.

[0065] Front part 30, main housing 10, and ring 20 can be made of metal or plastic. Preferably, however, front part 30, main housing 10, and ring 20 are made of metal, in particular aluminum or an aluminum alloy. This improves, among other things, the heat dissipation of the main housing 10 and results in a more robust design.

[0066] Fig. Figure 5 is another perspective view of the rear area of ​​the headlight 1. It shows that the main housing 10 has a cable feedthrough 17 in the area of ​​the cooling fins 15, adjacent to the ring 20, which is designed as a through-hole in the main housing 10.

[0067] The cable entry 17 is closed with a seal (not shown) through which the cable is passed.

[0068] In this embodiment, the cable entry 17 is offset laterally from the center of the headlight 1.

[0069] Fig. 6 and Fig. 7 are perspective views of the headlight 1, on which a first embodiment of a holder 60 is now mounted.

[0070] The holder 60 is designed to attach the headlight 1 to a handlebar.

[0071] The holder 60 comprises an arm 61 which is fixed by means of the screw 62 to a lateral fastening point (see Fig. 1) of the headlight or the main housing 10 of the headlight.

[0072] Furthermore, the holder 60 comprises a clamp 63.

[0073] The clamp 63 is divided into two halves by the joint 64.

[0074] As shown in the perspective view according to Fig. 7, the two halves of the clamp 63 can be pulled together by means of the screw 65 in order to fix the clamp 63 to a handlebar.

[0075] Fig. 8 shows a perspective view of the headlight 1, where now at an upper fastening point (see Fig. 2) a holder 70, for example for screwing to a frame component, is arranged.

[0076] The holder 70 comprises two upwardly projecting arms 71a, 71b.

[0077] The holder 70 is fastened by the screw 72 arranged between the arms 71a, 71b.

[0078] For fastening the headlight, the holder 70 comprises a through hole 73 which extends transversely through the arms 71a, 71b.

[0079] The holder 70 is mounted at the top on the side opposite the reflector 50.

[0080] The holder 70 can also be mounted below, in which case it sits behind the reflector 50 (not shown).

[0081] Fig. 9 shows a headlight 1 which comprises a holder 80 which is designed for attachment to the clamping shell 2 of a handlebar clamp.

[0082] The holder 80 comprises an arm 81.

[0083] The arm 81 is connected to another arm 84 via a screw 82. The arm 84 is fixed to a lower attachment point (see Fig. 3) screwed on.

[0084] After loosening screw 82, the headlight housing can be adjusted in its inclination.
