Description

Field of the invention

[0001] The invention relates to a bicycle headlight. Furthermore, the invention relates to a bicycle equipped with a bicycle headlight. Background of the invention

[0002] Bicycle headlights with a battery are known. For example, document DE 20 2018 105 194 U1 shows an angled headlight that can be clamped to the handlebars using an elastic band next to the handlebar clamp, thus positioning it centrally on the bicycle.

[0003] Battery-powered headlights are also a good alternative to flashlights. However, the disadvantage of carrying most common battery-powered headlights is that the mount for attaching them to the bike is usually part of the headlight housing. Furthermore, the headlight is difficult to grip. Object of the invention

[0004] The invention is based on the object of providing a bicycle headlight which can be easily attached to the bicycle and which can be carried in an improved manner as a flashlight. Summary of the invention

[0005] The object of the invention is already achieved by a bicycle headlight according to one of the independent claims.

[0006] Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

[0007] The invention relates to a bicycle headlight.

[0008] This comprises a main housing which is cylindrical in shape at least in sections.

[0009] The main housing is designed as an elongated handle so that the bicycle headlight can be carried as a flashlight.

[0010] At least one battery is located in the main housing.

[0011] The main housing transitions into an angled head in a transition area. The angled head preferably has a circular cross-section.

[0012] The head includes a lens. The lens is preferably designed as a projection lens. This allows for a compact spotlight.

[0013] A holder for attaching the bicycle headlight to the bicycle is arranged on the main housing, whereby the main housing can be removed from the holder without tools.

[0014] In particular, the holder encompasses the main housing.

[0015] This means that when the headlight is removed, no components of the mount protrude from the sides of the housing. This makes the bicycle headlight ideal for carrying as a flashlight.

[0016] Due to the angled head, a bicycle headlight can be provided which can be installed parallel to the stem, especially below or above the stem, and the light illuminates the road in front of the bicycle in a legally compliant manner.

[0017] Mounting it parallel to the stem also allows for a relatively large main housing with a correspondingly large battery. The mount can also wrap around the main housing close to the center of gravity.

[0018] The main housing can have an elongated cross-section, particularly a slotted hole. This makes it easy to grasp.

[0019] At the same time, two round cells can be arranged in parallel in the main housing as a battery.

[0020] In one embodiment of the invention, the head is angled relative to the main housing by 5 to 30°, preferably by 10 to 20°. The angle refers in particular to a central axis of the main housing relative to the central axis of the lens.

[0021] In a further development of the invention, the main housing can be inserted into the holder in two positions rotated 180° to each other. This allows the headlight to be mounted both below and above the stem.

[0022] In one embodiment of the invention, the main housing has a length of 40 to 100 mm, preferably 55 to 75 mm, a width of 30 to 50 mm, preferably 35 to 45 mm, and / or a height of 10 to 30 mm, preferably 15 to 25 mm.

[0023] In one embodiment of the invention, the angled head has an outer diameter approximately equal to the width of the main housing. This allows for the provision of a headlight that is compact, particularly when viewed from the front.

[0024] The invention further relates to a bicycle headlight, in particular with at least one of the features described above.

[0025] The bicycle headlight includes a holder that can be attached to the bicycle and surrounds the bicycle headlight, whereby the bicycle headlight can be pushed out of the holder without tools.

[0026] In particular, a main housing of the bicycle headlight can be pushed out of the holder without tools.

[0027] The main housing can become jammed, especially in the holder.

[0028] In one embodiment of the invention, the holder comprises a snap closure with an operating lever by means of which the main housing of the bicycle headlight can be clamped.

[0029] In particular, the holder is designed as a clamp with a snap closure.

[0030] The clamp can be pulled together using the lever of the snap lock, thus clamping the main housing in place.

[0031] Such a snap closure comprises a pivoting lever which is connected to the opposite side of the clamp via a pull rod.

[0032] When the lever is closed, a dead point is exceeded, from which point the lever is clamped into the closed position.

[0033] Such a dead center can be provided in particular by arranging the pivot axis of the lever further out on the clamp than the axis connecting the lever to the pull rod.

[0034] The clamp has a shape adapted to the cross-section of the main housing; in particular, the clamp can be designed in the shape of an elongated hole.

[0035] In a further development of the invention, the main housing comprises a rail along which the main housing can be moved in the holder.

[0036] In particular, the main housing may comprise a groove into which an extension of the holder engages.

[0037] This means the bicycle headlight can be positioned differently depending on the stem.

[0038] The rail preferably extends only part of the length of the main housing. This provides a stop in the axial direction at the front and rear.

[0039] The lever can extend from a long side of the holder into a corner or narrow side of the holder, wherein a gripping hole for grasping the lever is arranged in the corner or narrow side.

[0040] This makes it easy to grasp the lever to release the snap lock.

[0041] Preferably, the lever is recessed into the holder's housing. In particular, the lever can be flush with the main housing on the outside.

[0042] The invention further relates to a bicycle which comprises the bicycle headlights described above.

[0043] In particular, the main body of the bicycle headlight is mounted parallel to the stem of the bicycle. Brief description of the drawings

[0044] The subject matter of the invention will be described below with reference to Fig. 1a to Fig. 6 will be explained in more detail. Fig. 1a and Fig. 1b are perspective views of a bicycle headlight according to the invention together with a holder. Fig. 2a and Fig. 2b are perspective views of the bicycle headlight without holder. Fig. 3a and Fig. 3b are perspective views of the holder. Fig. 4 shows a sectional view of the holder. Fig. 5 is a perspective view of the bicycle headlight and lens. Fig. 6 is a cross-section of the main body. Detailed description of the drawings

[0045] Fig. 1a and Fig. 1b are perspective views of an embodiment of a bicycle headlight 100 and holder 200.

[0046] The bicycle headlight 100 comprises a main housing 110 with an elongated, in particular slot-shaped cross-section, which merges into an angled head 130 in a transition region 120.

[0047] The head 130 has a circular cross-section and comprises a lens 131 designed as a projection lens, which acts as a light exit surface.

[0048] The main housing 110 is closed at the back with a cover 111, which can be removed to replace the battery.

[0049] The holder 200 is designed as a clamp which surrounds the main housing 110.

[0050] The holder 200 can be mounted on the bicycle via a mounting bracket 201 with a through hole 202. The mounting bracket 201 comprises two outwardly projecting arms arranged parallel to each other.

[0051] In particular, a carrier with a through hole can be mounted on the bicycle, in particular with a clamp (not shown), which is connected to the fastening tab 201, for example by means of a screw.

[0052] The head 130 comprises side windows 134, which form a lateral light exit surface and thus improve traffic safety.

[0053] The battery in the main housing 110 can be charged via a USB port 132 on the head 130.

[0054] Furthermore, the head 130 includes a switch 133 with a charge level indicator and / or status indicator. In particular, the headlight can be switched on at several brightness levels.

[0055] Pressing the switch 133 switches on the headlight 100.

[0056] According to one embodiment, the headlight 100 may have a high beam function that can be activated, for example, by pressing the switch 133 twice.

[0057] Fig. 2a and Fig. 2b are perspective views of the headlight without bracket.

[0058] The main housing 110 is provided with a groove 112 on both the top and bottom, which extends sectionally over the main housing 110.

[0059] In cooperation with the holder, a rail system is provided by means of which the headlight 100 can be displaced axially relative to the holder.

[0060] The diameter of the head 130 corresponds to the width of the main housing 110.

[0061] There are no mounting components protruding from the headlight housing of the 100 headlight for attachment to the bicycle.

[0062] Therefore, the headlight 100 can also be used as a flashlight, with the main body 110 serving as a handle.

[0063] Fig. 3a and Fig. 3b are perspective views of the holder 200.

[0064] The holder 200 is designed as a clamp.

[0065] The inner wall of the holder 200 comprises an extension 203 which, when mounted, engages in the groove of the main housing of the headlight.

[0066] In the illustrated embodiment, the extension is arranged on the opposite side of a snap closure with the lever 210.

[0067] In another embodiment (not shown), the extension is located on the same side as the snap lock. This can facilitate removal of the headlight from the holder.

[0068] Thus, the headlight can be inserted into the holder 200 in two positions rotated by 180° to each other. In particular, the headlight can be mounted using the holder 200 both above and below the stem.

[0069] In order to tighten the holder 200, which is designed as a clamp, it comprises a snap lock with a lever 210.

[0070] The lever 210 extends over the long side of the holder 200 into the rounded area of ​​the narrow side arranged in the corner.

[0071] There is a gripping hole 212 under the lever 210 to release the snap lock.

[0072] The lever 210 is pivotally mounted on the holder 200 via the axis 211.

[0073] Furthermore, the lever 210 comprises two arms 215, between which a pull rod 213 is seated, which engages in a recess 216 on the opposite side of the clamp and is connected to the clamp via the axis 214.

[0074] The axis 211, over which the lever 210 is pivotally mounted, is located further out than the connecting axis between the pull rod 213 and the lever 210 (see Fig. 4).

[0075] When the snap lock is closed, a dead point is exceeded, from which point the lever 210 is pushed into the closed position shown here.

[0076] The axle 211 is located between the axle 214 and the axle (217 in Fig. 4), with which the pull rod 213 is connected to the lever 210.

[0077] The lever 210 extends in sections over the entire height of the clamp.

[0078] When closed, the lever 210 is flush with the housing of the holder 200.

[0079] Fig. 4 is a sectional view of the holder 200.

[0080] This sectional view shows the axis 217, via which the pull rod 213, which sits between the arms 215, is movably connected to the lever 210.

[0081] The axis 217 is located at the same height as the axis 214, via which the pull rod 213 is pivotally connected to the opposite side of the clamp.

[0082] Fig. 5 is a perspective view, with the lens 131 now shown separately.

[0083] The lens 131 is formed as a substantially truncated cone-shaped solid body made of a transparent material, in particular of glass or a transparent plastic, such as polymethyl methacrylate.

[0084] The lens 131 is held in the head 130 by means of the ring 135.

[0085] Below the lens 131 there is a circuit board 136 with an LED chip 137.

[0086] Part of the light from the lens 131, which is designed as a solid body, leaves the head 130 via the side windows 134.

[0087] The lens 131 comprises a concentric ring 138, particularly designed as a ridge, which divides the projected light field into at least two zones. An inner zone forms a focused light field.

[0088] The lens 131 can be designed such that the light field is cut off at the top in order to avoid glare. This can be achieved in particular by a stepped inner zone (not shown).

[0089] The LED chip 137 is arranged coaxially to the lens 131.

[0090] Fig. 6 is a cross-section through the main housing 110.

[0091] Due to the slotted design, a battery with two round cells 113 can be used. This makes it easy to provide a battery with a large capacity while simultaneously requiring a relatively small installation space.

[0092] The invention made it possible to provide a bicycle headlight which can also be used as a flashlight in an improved way.
