Definitions
- the invention relates to an anti-theft device for bicycles, which have a bicycle frame and a steering column mounted on the bicycle frame for steering the bicycle, which is provided for a rotationally fixed coupling of a bicycle handlebar with a fork for a front wheel, with a separating means for releasing the rotationally fixed coupling.
- Such anti-theft devices are known.
- the aforementioned anti-theft device enables the bike to be further secured against theft, since the thief, even if he is is ready to use force, can not cancel the effectiveness of the theft protection without damaging the bicycle.
- a classic locking principle is used, which consists in bringing relatively movable parts on the object to be secured into a more or less fixed or stationary position, so that the mobility of the parts is restricted and the object is in the locked position is not usable.
- the object to be secured is a bicycle
- it is known to become a free one Rotation of the rear wheel is prevented, for example, by placing the U-lock both around a tube of the bicycle frame and around a section of the rim of the rear wheel and then locking it.
- the U-lock can also be placed around the tube of the bicycle frame and around a stationary object such as a lamppost, in order to prevent the mobility of the bicycle as a whole.
- WO 92/10392 discloses a handlebar locking device for bicycles.
- the device has a locking mechanism in a handlebar stem, which either brings the handlebar stem into engagement with the front fork in the unlocking position or separates it from the locking position in such a way that the steering support and the front fork are freely rotatable relative to one another.
- a steering column fastened to the front wheel fork and a pipe section fastened to the handlebar stem are rotatably connected to one another in the unlocking position and rotatable together in a bicycle frame section.
- a cam actuated by means of a key moves a roller lock arranged in the steering column radially outward and introduces it into a socket in the pipe section for unlocking, so that the bicycle is controllable.
- the cam also allows the roller lock to be inserted into an opening which is provided for separating the front wheel fork from the handlebar stem, so that the bicycle cannot be steered and is therefore secured against theft.
- the known anti-theft device thus works in reverse of the above-described security principle, namely that a fixed connection required for operating the bicycle between two parts is canceled in the security position.
- the known anti-theft device does not offer any practical possibility of releasing the lock using force.
- the known anti-theft device is nevertheless disadvantageous in that a skillful thief can pick it up to unlock the bike without destroying it. This is a problem, particularly with regard to securing high-quality bicycles, which are naturally particularly interesting for the thief and in which, in order to maintain their resale value, the use of brute force for the conscientious thief is out of the question, so that the thief is ready to unauthorized unlocking of the anti-theft device in detail and to learn.
- the invention has for its object to provide an anti-theft device for bicycles, the unlocking of which presents a thief with a considerably more difficult task than known anti-theft devices.
- a coupling piece or a connecting element is provided as a separating means, which interrupts the steering column in two parts and produces the rotationally fixed coupling of these steering column parts in a first state and cancels them in a second state ,
- an anti-theft device is obtained which is significantly more difficult to unlock than known anti-theft devices when the coupling piece or the connecting element is removed from the bicycle by a user in a securing position.
- the anti-theft device according to the invention is highly integrated into the bicycle.
- the coupling piece or the connecting element is essentially mirror-symmetrical or point-symmetrical. On both sides of the plane of symmetry, it has recesses and / or shoulders which, in the first state, are in engagement with complementary means formed on the steering column parts and thereby enter into a positive and / or non-positive connection and are released from the complementary means in the second state.
- the coupling piece is formed with a column piece which is inserted between the parts of the steering column in the first state and is flush with it and which is completely removed from the parts of the steering column in the second state.
- the bike In the first state, the bike is unlocked.
- the inserted between the parts of the steering column column enables a rotationally fixed connection of the parts of the steering column with each other, so that the steering column with the coupling piece according to the invention is practically not restricted in its function compared to a conventional steering column.
- the bike is secured.
- the parts of the steering column are coaxially spaced from each other.
- the coupling piece which was completely removed in the second state, is required in order to restore a connection between the parts of the steering column and thus the functionality of the steering column. Unless a suitable coupling piece is inserted between the parts of the steering column, the use of the bicycle is excluded and therefore uninteresting for a thief. Furthermore, the coupling piece has two coupling sleeves arranged axially next to one another. The pillar piece is received in the coupling sleeves. The coupling sleeves have external threads which are provided for engagement with an internal thread in the respectively adjacent section of the bicycle frame. In the locking position, the coupling sleeves are axially adjacent, in the unlocking position they are spaced apart.
- the coupling sleeves are screwed into the adjacent section of the bicycle frame. If the coupling sleeves have the same thread, the direction of rotation of the coupling sleeves is opposite to each other when screwing in and out. It is advantageous if the coupling sleeves have threads running in opposite directions to one another, because then the directions of rotation of the two coupling sleeves match when screwing in and out.
- the pillar piece is preferably coaxially rotatable about its longitudinal axis in the coupling sleeves and furthermore axially displaceable.
- the external threads on the coupling sleeves and the associated internal threads in the respectively adjacent section of the bicycle frame are individually matched to one another. Due to the individual coordination of the threads to be brought into engagement with one another, only the external threads located on the associated coupling pieces can be screwed into the respectively adjacent section of the bicycle frame.
- a coupling piece other than the individually provided coupling piece has coupling sleeves whose external threads cannot be brought into engagement with the internal thread of the respectively adjacent section of the bicycle frame.
- the threads are preferably multi-start, so that a relatively large axial movement of the coupling sleeves is possible with one rotation of the coupling sleeves. It is particularly preferred that only one rotation of the coupling sleeves around the pillar piece is sufficient to achieve an axial movement about a predetermined insertion length of the respective coupling sleeves. In this preferred embodiment of the invention, a simple rotation of the coupling sleeves is sufficient to secure or unlock the bicycle.
- the pillar piece and the coupling sleeves are received in a protective tube.
- the protective tube can be detached from the bicycle frame and has axially displaceable drivers.
- the drivers take the coupling sleeves when the Protection tube relative to the bike frame with.
- the drivers are preferably designed as radial pins which project outwards through at least one axial elongated hole in the protective tube and of which one of the pins is in engagement with one of the coupling sleeves.
- the protective tube protects the user from soiling, such as that caused by lubricants emerging from the connection between the coupling sleeves and column pieces.
- the protective tube also protects the column piece and the coupling sleeves against the ingress of contaminants and moisture, which in particular provides effective protection against corrosion.
- the protective tube When the device is in the unlocking position, the protective tube also protects the adjacent portions of the bicycle frame from the ingress of contaminants and moisture. For the user, the protective tube reduces the risk of injury, since it preferably closes smoothly with the bicycle frame, so that the operation of the anti-theft device is particularly simple. Because the protective tube fits into the bicycle frame, the anti-theft device according to the invention is arranged particularly inconspicuously in the bicycle. Alternatively, the protective tube can be conspicuously designed to highlight the anti-theft device on the bicycle and to present it to the user as a desirable product.
- the connecting element is designed in the form of a ping or frame. It has engagement brackets which are provided for engagement with claws of the steering column parts in the first state. In the first state, the unlocking position, each engagement bracket is gripped by the claw of the associated steering column part. The engagement brackets move from the first state into the second state by a first rotary movement of the connecting element about its central axis in a preferably right angle to the axis of the steering column. In the second state, the securing position, the connecting element is freely supported between the steering column parts. The connecting element can be transferred from the second state, the securing position, into the first state, the unlocking position, by means of a second rotational movement opposite to the first.
- the connecting element In the second state, the connecting element can be removed from or inserted into the steering column through an opening in the wall of the bicycle frame section with the steering column.
- the securing is particularly effective when the connecting element is completely removed from the steering column. It is a very difficult task for the thief to make the connection between the steering column parts if the suitable connecting element is not available to him.
- the connecting element preferably has an individual profile or fitting profile on a section of the engagement bracket facing the central axis, which can be brought into engagement with a complementary profile or fitting profile on the claws. Because of the complementary profile on the claws, the individual profile must be formed on the assigned section of the connecting element to unlock the anti-theft device according to the invention. This makes unauthorized unlocking even more difficult.
- the engagement brackets of the connecting element are optionally separated from one another in the plane of symmetry and are arranged so as to be radially displaceable with respect to the central axis.
- the engagement brackets can be brought into engagement with locking recesses in the steering column parts.
- the axial sections of the locking bracket can be brought into engagement with recesses in the end faces of the steering column parts. If, in the unlocking position, the spreader frame halves are respectively engaged in the end faces of the steering column parts, it is ensured that an uncontrolled turning back from the unlocking position, in which the steering column parts are non-rotatably connected, to the securing position, with the steering column parts separated from one another and freely rotatable with respect to one another are excluded. This ensures the operational safety of the bicycle when the anti-theft device is in the unlocking position.
- the engagement brackets form an inner ring which is surrounded by an outer ring.
- the outer ring has locking brackets which are separated from one another to form end faces, preferably in the plane of symmetry of the connecting element.
- the locking brackets are each slidably mounted on the associated engagement bracket of the inner ring.
- the locking brackets are biased against each other.
- the outer ring also has one or more expansion elements for pushing apart the locking brackets against the bias.
- the spreading elements are each rotatably mounted about the central axis between the end faces of the locking bracket. The locking brackets can be pushed apart by rotating the expansion elements.
- the operational safety is particularly high because the connecting element in the unlocking position is gripped both positively and / or positively by the claws and in the corresponding recesses in the steering column parts when the locking brackets are pushed apart.
- the cross-sectional profile of the expansion element in a plane penetrated at right angles by the central axis is essentially rectangular with two broad and two narrow sides, which are opposite each other. If the connecting element is inserted between the steering column parts in the securing position, the spreading elements are arranged between the locking brackets of the outer ring in such a way that they press with the end faces of their free ends against the broad side faces of the spreading element.
- the opposingly arranged end faces of the locking bracket are spaced apart from one another. which essentially corresponds to the narrow side of the rectangular cross-sectional profile of the expansion element
- the connecting element When the connecting element is inserted between the steering column parts and the expansion elements are rotated, the locking bracket and the engagement bracket follow a first quarter-circle rotation of the expansion elements.
- the engagement bracket is gripped by the claws.
- the connecting element cannot follow a second quarter-circle rotation of the spreading elements about the central axis, since the engagement ball is gripped by the claws. Therefore, the second quarter-turn means that the expansion element between the end faces of the locking bracket is rotated by 90 °.
- the locking bracket is pushed apart or spread apart by the expansion element in accordance with the length difference between the broad side and the narrow side of the cross-sectional profile of the expansion element.
- the cross-sectional profile of the expansion element preferably has rounded corners, so that the rotatability of the expansion element between the end faces of the prestressed locking ball is increased
- the sides of the cross-sectional profile of the expansion element are preferably of concave design.
- the cross-sectional profile of the locking bow in the section of the free ends is preferably of such a convex shape that the locking ball with the convex end face nestles against the concave side surface of the expansion element Ver rotation of the expansion elements is particularly low Bicycle in the unlocking position of the anti-theft device according to the invention is particularly high.
- the anti-theft device according to the invention described above is located in a bicycle with a bicycle frame and a steering column mounted on the bicycle frame for steering the bicycle, which is provided for a rotationally fixed coupling of a bicycle handlebar with a fork for a front wheel.
- the anti-theft device according to the invention described above is particularly suitable for the theft protection of bicycles, the person skilled in the art can easily open up further areas of application, such as securing motor-driven two-wheelers or other vehicles which have a steering column.

- the threads are designed in opposite directions to one another.
- the two coupling sleeves 24 of the coupling piece 8 are each a driver 30 is attached, which is designed as a pin and projects radially through an elongated hole 32 (see FIG. 5) in the wall of the protective tube 28 into the interior of the driver locking device 40.
- the coupling sleeves 24 lie against one another, while according to FIG. 4 the coupling sleeves 24 are screwed into the respectively adjacent section of the steering head tube 26 by rotating the protective tube 28
- the structure of the driver locking device 40 is shown in FIG. 5.
- the driver locking device 40 has the housing 42 integrally molded or fastened on the protective tube 28 (cf. FIGS. 2-4), a push button 44 and an abutment 46, each of which is box-shaped in this way that they can be inserted into each other in the bottom 47 of the abutment 46 there is a central elongated first locking hole 56 and two spaced apart in the longitudinal direction of the coupling piece 8 pe phere second locking holes 57th

- the drivers 30 protrude into the interior of the housing 42. If the distance between the drivers 30 corresponds to the distance between the second locking holes 57 in the bottom 47 of the abutment 46, the drivers 30 are in a first locking position and are each received by the assigned second locking hole 57. If the drivers 30 are adjacent to one another, they are in a second locking position and are received together by the central first locking hole 56 in the bottom 47 of the abutment 46.

- expansion elements 78 are each clamped between the locking brackets 72 that are prestressed against one another, there is a non-positive connection between each expansion element 78 and the legs 73 of the locking bracket 72 that press against this expansion element 78.
- the non-positive connection is supplemented by a positive-locking connection, since in each case the convexes are convex Fit the end faces 90 of the locking bracket 72 to the associated concave side faces of the expansion element 78.
- the parallelepiped-shaped spreading elements 78 abut the end faces 90 with the surface of the broad side 81, the locking balls 72 are spaced apart from one another by the length of the narrow side 80 of the spreading elements 78. If, on the other hand, the spreading elements 78 abut the end faces 90 with the face of the narrow side 80 (cf. FIG. 8), the locking balls 72 are spaced apart from one another by the length of the broad face 81.

- the torque applied by the user is sufficient to cancel the non-positive and positive connection of the expansion elements 78 to the locking brackets 72, the expansion elements 78 alone follow this further rotation of the key.
- the locking brackets 72 are pushed apart a little further than before, because the spreading elements 78 are rotated between the locking brackets 72 in such a way that the distance of the locking brackets 72 from one another is now determined by the length of the broad side 81 instead of the narrow side 80 of the expanding element 78 (see also Fig. 8).
- the locking bracket 72 are received by locking recesses 84 formed in the steering column parts 34 (see FIG. 7), so that an uncontrolled turning back of the connecting element 60 into the securing position is not possible.
- the connecting element 60 is thus reliably locked in the unlocking position.
- the user For a transition of the connecting element 60 into the securing position, the user must first turn the spreading elements 78 - according to the representation of FIGS. 9-1 12 counterclockwise - before he then rotates the connecting element 60 into the securing position and removes it from the steering head tube, whereby the rotatable coupling of the bicycle handlebar 6 with the fork 5 is completely removed.
