Additional equipment for bicycle lighting systems

The currently known additional devices for bicycle lighting { DE 28 21 853, DE 35 43 718 ) have blatant functional limitations which only allow partial operation of the lighting system under certain circumstances or lead to the failure of the lighting.

If a bicycle equipped with a conventional lighting system is brought to a stop, the lights go out. This situation poses many risks for the cyclist and other road users.

This version presented here has the following features that solve this problem and the features

- a power-enhanced direct current dynamo (4) that ensures the power supply

- a built-in voltage regulator (12) that regulates the current flow

- an automatic switching element (8) which, depending on the power supply of the dynamo, decides between battery or dynamo operation of the lighting

- Safety circuit against possible self-discharge of the battery by means of a blocking diode (13)

- Key switch (7) for commissioning and as protection against unauthorized switching on of the lighting

- mounting unit {2} firmly connected to the bicycle frame, which has a receiving device with a locking lock (24) for the battery and control unit (2) which is intended to prevent unauthorized removal of the battery and control unit (2)

- Switch (17) on the holder unit (2) equipped with connection contacts (5, 6, 15, 18) for the possibility of charging the battery while driving using a dynamo (4) without the lights switched on (19, 20)

- Possibility of connecting an external power source to charge the battery (14) to socket (21)

- optionally an integrated power supply unit (25) for charging the battery (14), the removed unit (3), at a 220V socket

for which I request protection.

The lighting system is designed in this way, and provided it is handled correctly, it is guaranteed to be fully functional at all times. The security measures provided to prevent tampering or removal are a prerequisite for the bike to function at all times.

The components can be retrofitted to any commercially available bicycle simply by self-assembly.

An example of this additional device is shown in Figure 4, which shows the holder unit (2) with the battery and control unit (3) mounted on the bicycle frame.

Figure 3 shows a schematic of the lighting system without the battery and control unit in operating state.

Claims (1)

Reference number: G 94 20 459.4 Protection claims: 1. Additional devices for bicycle lighting systems (Fig. 1) which have a battery and control unit (3) which can be removed from a holder (2) and recharges itself during the ride, which ensures the uninterrupted operation of the lighting system (19, 20) and has a reinforced direct current dynamo (4) as a power source, whereby an external power source for charging the battery can also be connected to the socket (21) and is composed of -key switch (7) which has two separate switching contacts, the first between the plug connection (6) and the input side of the blocking diode (9) with a connection for controlling the switching element (8) and the second between the output side (8b) of the switching contact on the switching element (8) and the plug contact (15), -Blocking diode (9) which is connected on the input side to the key switch at the output of the first switching contact (7b) and on the output side to the
-Resistance (10) Connection has the second Connection with
-Capacitor (11) whose line is connected to the input of the -Fixed voltage regulator (12) which is also connected on the input side to the output side of the blocking diode (22) and whose output current is directed to the input side of the -blocking diode (13) which has a conductive connection on the output side to the positive pole of the -battery (14) which is connected on the positive pole side to contact (8a) on the -switching element (8) which has a connection via connection (8b) to the key switch (7) on the contact (7c - 7d) with plug contact (15), -Holder unit (2) with built-in blocking diode (16) which is connected on the input side to the terminal (5), plug contact (6) and on the output side to the plug contact (15) and connection (17a) on the -Switch (17) which has a conductive connection to terminal (18) at connection (17b), -Lock (24) and -Cable connections to the housing on the components battery (14), fixed voltage regulator (12), capacitor (11), switching element (8) and plug contact (23). Additional devices (Fig. 2) according to claim 1 - wherein the battery and control unit (3) has a power supply unit (25) and a blocking diode (26) which has a connection to the power supply unit (25) on the input side and to the positive pole of the battery (14) on the output side.
