[Title of Invention:] bicycle lock

[Description]

The invention relates to a lock for bicycles,

[State of the art]

Bicycles are secured against theft using special locks, where absolute security can not be achieved. Even the most stable and most complicated locks are in enough time and effort to be opened by unauthorized persons. Against spontaneous theft, however, most locks offer good protection.

In the German Offenlegungsschrift DE 42 32 540 Al a lock for single-track vehicles is described which consists of a tubular container in which a centrally mounted drum is arranged, on which a rope is wound, wherein the one end of the rope on the drum is attached indissolubly and the other end of the cable carries a safety lock half which is for the purpose of locking insertable in a second at the top of the container inextricably fastened safety lock half.

The disadvantage of this bicycle lock and all other known bike locks is that it - if at all - is secured with a special holder on the bicycle and that the seat post and the saddle connected thereto are not included in the protection. [Object of the invention]

The invention has for its object to provide a bicycle lock which is to ATTACHING without special holder on the bike and are secured with both the bike and the seat post and the saddle connected thereto.

The object is achieved by an invention having the features of the main claim. Advantageous embodiments are specified in the subclaims.

[Examples]

The invention using an exemplary embodiment is explained, game.

Figure 3 shows an inventive bicycle lock, combined with a tail lamp,

Figure 4 shows an inventive bicycle lock, combined with an acoustic signal transmitter and a transmitter.

1 shows an inventive bicycle lock 1, consisting of a housing 2 and a rotatably mounted in the housing 2 drum 3 on which a rope 4 is completely wound up. The housing 2 has an opening 6, through the the rope 4 is guided to the outside. The rope 4 is fastened at one end to the drum 3 and carries at the other end guided towards the outside a lock half 5a, which is connected to the arranged in the housing 2 lock half 5b and (not shown) there by means of a safety lock can be fixed.

The safety lock 5 is preferably a combination lock that is opened via a net adjusted combination. The locking and unlocking of the lock 5 can also, for example via a radio signal.

Between the housing 2 and the drum 3 a helical spring 7 is arranged, which spans by the rotation of the drum 3 when pulling of the rope 4 and the omission of the

Load the drum 3 to rotate back until the rope 4 Celtic aufgewik- or stretched.

The housing 2 has a centrally arranged cylindrical opening 8 in which a sleeve 9 is arranged. The outer diameter of the sleeve 9 corresponds to the diameter of the aperture 8 and the inner diameter of the sleeve 9 corresponds to the diameter of the seat post 10th

The sleeve 9 is rotatably connected to the housing. 2 This can be done so that the sleeve has at least at one end a circumferentially arranged nose 11 which engages in a corresponding recess of the shape of the nose 12 of the housing second

The sleeve 9 is fixed to the seat post 10 in order to ensure a defined position of the bicycle lock. 1 The fixing of the sleeve 9 is effected in this embodiment by a nut 13, which the over the length of the thread slotted end (not shown) of the sleeve 9 presses against the seat post 10, thus creating a positive connection between seatpost 10 and sleeve. 9 At the same time the mother pushes the housing 2 13 against the tabs 11 of the sleeve. 9

As shown in Figure 2, the sleeve 9 can be dispensed with and be implemented as part of the housing 2, in which only one of the threads and the nut element 13 corresponding fastening is to be arranged, which ensures the firm connection between the housing 2 and seatpost 10th The connection between the housing 2 and the sleeve 9 and seat post 10 is not limited to the illustrated shape, but may be effected by means of other known fasteners. The use of fertil sleeves 9 but has the advantage that the bicycle lock according to the invention 1 can be adapted to seat posts 10 having different diameters or cross-sectional shapes by the use of sleeves 9 having different inner diameters or inner cross-sections.

According to a further embodiment, the bicycle lock 1 of the invention is combined with a reflector fourteenth The location of the bicycle lock 1 to the seat post 10 and its defined position offer optimum conditions for the arrangement of retro-reflector on the bicycle lock 1. Figure 3 shows the connection of the bicycle lock 1 according to Figure 1 with a rear reflector 14. The reflectors 14 consists of a transparent hood 15 which is connected to the housing second Under the hood, 15 light-emitting diodes 16 are arranged, which are powered by a battery 17th The electrical connection is produced or interrupted by a switch 18th

The bicycle lock 1 of the invention is according to a further embodiment (Figure 4) with an acoustic signal transmitter 19 combined, which is then activated when the rope 4 is severed. The signal generator is powered by the battery 17 and is adjusted so that the acoustic signal for about 30 seconds when in such a volume that the signal can be heard up to a distance of 300 m. The acoustic signal generator can be additionally provided with a motion sensor (not shown) can be connected, the already then triggers an alarm when the bicycle within a certain time of a certain number of movements is exposed.

Another embodiment of the bicycle lock according to the invention provides that the acoustic signal generator 19 is connected to a transmitter 20, which - once the switch is triggered - a message is transmitted to the mobile phone of the owner and / or broadcasting a radio signal of a localization bicycle lock (and thus of the bicycle) via positioning systems, such as GPS, possible.

The reflex reflector 14 is electronically connected to the security lock 5 in such a way that it can be activated only when the safety lock is not closed. This prevents that the battery 17 is discharged, with the aim to prevent the triggering of an alarm.

The bicycle lock according to the invention may be designed such that its operation (locking and unlocking of the lock 5, the turning of the reflector; stopping the alarm, etc.) via a radio remote control, the remote control may be self-secured by a PIN , This has the advantage that only the owner of the remote control is capable of serving the bicycle lock. 1 [LIST OF REFERENCE NUMBERS]
