Definitions
- the invention relates to a lighting device, in particular for bicycles.
- a disadvantage frequently described in the prior art is the unreliable energy supply of conventional lighting systems by means of side dynamos.
- This type of dynamo often slips when it is wet, snow or dirty on the road, and there is a failure or a strong decrease in the performance of the dynamo, which is associated with a high safety risk, especially in the dark.
- the disadvantage is also known that the current lighting systems for two-wheelers only identify the central or longitudinal axis of the vehicle in the form of front lighting and rear lighting.
- a brake light on a bicycle is known from DE 298 23 608 U1, which also works as a battery-operated rear light.
- Such battery-operated taillights are attached to the bicycle or to the rider himself, for example, with special holding devices and enable failure-free operation, even when the bicycle is at a standstill.
- DE 201 09 031 U1 an integrated bicycle electrical system with direction indicator and automatic lighting system is known, which contains a battery to overcome the unreliable energy generation by means of a dynamo, which supplies the front and rear lights of the bicycle with electricity.
- the known battery-operated illuminations or additional set illuminations for bicycles also have a disadvantage, namely that these illuminating devices have to be designed by means of special holding devices on the driver or on the bicycle using clamps or clamps.
- a reliable fastening device for two-wheel vehicle parts is disclosed, which allows the fastening of lighting devices to the bicycle via a modular structure.
- a disadvantage of this construction is that different fastening clamps for different types of bicycles or handlebars have to be provided in order to use the lighting device on each bicycle.
- a signaling device for bicycles is disclosed which, by means of flexible arms and a central fastening, enables the free positioning of two display means within the scope of the circumference of the flexible arms. These flexible arms are connected to a box for receiving the electrical energy source and are attached to a holder, for example on the handlebar, by means of fastening means.
- the lighting devices for bicycles cited in the prior art have in common that the lighting means are arranged in each case in the vicinity or on the longitudinal axis of the vehicle, as a result of which lighting of the vehicle is marked forwards and backwards. With the known lighting devices, it is not possible to make the width of the vehicles recognizable to road users in the dark.
- Another disadvantage of the prior art is that the operational readiness of the lighting devices, in particular with regard to the rear lighting, is not easily ascertainable for the driver. For example, it is more common for the rear lighting to fail without the driver noticing and this creates a safety risk.
- the object of the invention is to improve the lighting situation in bicycles and, furthermore, to make the operational readiness of the lighting device continuously checkable.
- the object is achieved by a lighting device which is designed as a handlebar plug with integrated lighting.
- the lighting device according to the invention is designed to be insertable and attachable to the handlebar ends on both sides of the handlebar body.
- the lighting device essentially consists of a Base body and a lighting cap protruding beyond the handlebar end, an electrical energy source being arranged in the base body, which supplies the illuminants arranged in the lighting cap with electrical energy.
- High-power LEDs which are arranged in the lighting cap, are preferably used as the illuminant.
- the lighting cap itself is connected to the base body with a locking mechanism, a bayonet lock being preferably used, via which the lighting cap is rotatably connected to the base body.
- the connection is carried out as a rotary switch via sliding contacts and at the same time serves to start up the lamps or the lighting device as a whole.
- the lighting cap is also connected to the base body with a locking mechanism, which is designed as a lobster clasp, as a result of which an anti-theft connection can be formed, since the lobster clasp can only be released with a special tool, in particular with a mandrel.
- the base body is connected to a slat body, which has holding slats for fixing the side of the lighting device facing away from the handlebar end.
- a cap receptacle is provided on the base body of the lighting device, which is pushed onto the handlebar base body.
- the holding slats are formed radially over the entire circumference of the slat body.
- the holding lamellae are designed to have different lengths to compensate for different inner diameters of handlebar base bodies.
- the tension of the larger slats can decrease due to excessive deformation during assembly and the resulting transition from the elastically deformed area to the plastically deformed area of the slat. The result would be a possibly inadequate fixation of the lighting device in the handlebar base.
- the formation of holding slats of different lengths enables the lighting device to be used for a wide range of applications in relation to the inside diameter of the handlebar base body.
- slat bodies with three or four different slat lengths can be implemented in order to further increase the universality of the lighting device, if necessary.
- the lighting cap In order to make the lighting cap mechanically stable, reinforcing lamellae are arranged in the lighting cap. This takes into account the special mechanical stress to which the lighting cap is exposed, for example by leaning the bicycle against a wall and the resulting contact of a handlebar end with the wall.
- the lighting cap is made of translucent polycarbonate and the base body and the slat body are made of polypropylene.
- illuminants of different colors are arranged in the lighting cap of the lighting devices, which signal the direction of travel when the orientation is determined.
- the solution according to the invention of the above-described object ensures that the lighting device is always ready for operation even when stationary, for example when stopping at a traffic light.
- the high-performance LEDs used according to the invention ensure minimal use of energy with maximum luminous efficiency.
- the system is also largely maintenance-free and wear-free and is characterized by a low weight and easy handling.
- the lighting situation of the bicycle is significantly improved by the lighting device according to the invention, and the maximum lateral extent of the bicycle transverse to the direction of travel is also better recognized by the other road users in the sense of position lights, which can more reliably recognize the distance to the bicycle to be maintained, for example, when overtaking ,
- the lighting is always ready for use.
- the lighting is also in the driver's field of vision, which means that the driver can immediately recognize a failure of the lighting device and appropriate measures can be initiated, whereas with conventional lighting the driver cannot recognize when, for example, the rear lighting fails. If the lighting has to be put into operation due to the weather conditions, the Drivers do not have to interrupt their journey first, but can operate it while driving.
- FIG. 1 handlebar end with lighting device FIG. 2 base body with lamella body of the lighting device and FIG. 3 lighting cap of the lighting device.
- the illustration shows a handlebar end 1.
- the handlebar base body 2 receives the base body 4 of the lighting device at the handlebar end 1.
- the lighting cap 5 connected to the base body 4 forms the end of the handlebar end 1 and simultaneously closes the handlebar end 1.
- the base body 4 receives the electrical energy source 6, for example in the form of two alkaline batteries or also rechargeable batteries. Furthermore, the base body 4 is connected to a lamellar body 9 and to the lighting cap 5 via the cap receptacle 14. The lighting cap 5 preferably connects to the handlebar grip 3. The illuminants 11 are arranged in a protected manner in the lighting cap 5 and illuminate the handlebar end 1.
- the lighting cap 5 is made of translucent polycarbonate.
- the lighting cap 5 also serves to accommodate the lighting electronics 7, which is snapped into the lighting cap 5.
- the lighting cap 5 serves to scatter the light emitted by the lamps 11 in order to illuminate a large area around the handlebar end 1.
- the base body 4 is connected to the slat body 9 via a hook-shaped anchor 12.
- the separate design of base body 4 and lamellar body 9 permits the use of a plastic which is particularly suitable for the lamellas 8 and their elastic requirements and which would not be suitable or would be too expensive for a complete design of the base body.
- the slats 8 can also be arranged directly on the base body 4.
- the electrical energy sources 6 for operating the illuminants 11 are placed in the interior of the base body 4.
- the side of the base body 4 facing away from the handlebar end 1 is fixed in the handlebar base body 2 by the slat body 9 attached to it.
- the holding slats 8 of the slat body 9 are designed according to a preferred embodiment of the invention according to FIG. 2 to different extents. This makes it possible to achieve sufficient stability by tensioning the slats in the installed state even with a variable inner diameter of the handlebar base body 2.
- the cap receptacle 14 delimits the base body 4 on the side of the handlebar end 1.
- the cap receptacle 14 is advantageously designed in such a way that it is partially pushed onto the handlebar end and thus serves directly on the handlebar end 1 for stabilizing the lighting device in the handlebar base body 2. This creates two breakpoints of the lighting device at the respective ends thereof, namely once through the lamella body 9 and each other through the cap receptacle 14.
- the locking mechanisms 13 for the connection to the lighting cap 5 are also arranged in the cap receptacle 14.
- two different locking mechanisms are used. This makes it possible, on the one hand, to turn the lighting cap 5 on the base body 4 by means of a bayonet lock 13.1, which then corresponds to a switch function via sliding contacts and enables the lighting device to be switched on and off.
- a bayonet lock 13.1 which then corresponds to a switch function via sliding contacts and enables the lighting device to be switched on and off.
- the second locking system namely the karabiner lock 13.2 snaps into place when the lighting device is assembled, thereby realizing effective theft protection.
- a mandrel is used as a special tool, which bends the retaining claw (not shown) of the lobster clasp back to release the connection.
- This advantageous embodiment of the actuation of the lighting device enables the same to be put into operation while driving, since the switching mechanism is in the area of the hands, which are usually located at the handlebar end 1.
- the formation of the lamellar body 9 through the different lamellar diameters is particularly advantageous. This is necessary because the usual handlebar dimensions are standardized only in the outer diameter, but the wall thicknesses can vary.
- the slat body 9 protects the lighting from being pulled out of the handlebar.
- the lighting device in the area of the lighting cap 5 is pushed onto the handlebar via the cap receptacle 14 and is therefore very well supported on the handlebar and also withstands loads from lateral forces.
- the use of high-power LEDs ensures very high efficiency. These have the advantage of realizing a very high luminous efficiency with very low power consumption. An external power source is thus dispensed with and the necessary electrical energy sources 6 can be integrated into the base body 4. This has the further advantage that the lighting does not switch off at a traffic light when there is no power supply, but that the cyclist can also be seen with his bicycle in a standing position.
- the lighting cap 5 is shown in a top view, the formation of reinforcing lamellae 10 being recognizable.
- the reinforcing lamellae 10 are preferably designed as a fan construction and increase the mechanical resistance of the lighting cap 5 and make it insensitive to falling and impact damage when installed with the lighting device at the end of the handlebar.
- two differently colored LEDs 11.1 and 11.2 are used as illuminants 11.
- a red LED 11.1 is used to mark the back and a yellow LED 11.2 to mark the front. This means that road users can see the direction of the bike from the side at a glance.
- the lighting electronics 7 are designed in such a way that pulsed operation of the lamps 11 is possible with electrical energy and an extension of the life of the electrical energy sources 6.
- the bicycle is illuminated at its outer points, namely at the handlebar ends, which makes the actual width of the wheel and the direction of travel visible to the other road users.
- the lighting situation for bicycles is thus effectively improved.
- the operational readiness of the lighting device can be continuously checked by the driver, so that safety risks in the event of lighting failure can be recognized immediately.
