Technical area

The invention relates to a switch, in particular for mounting on a bicycle handlebar, comprising a fixed part and a, between at least a first switching position and a rest position relative to the stationary part movable switching element. Furthermore, the invention relates to a handlebar comprising such a switch. State of the art

Electronic switches for bicycles for shifting electronic bicycle transmissions such as multi-speed hubs or derailleurs are known in the art. For example, there are electronic switches, which are equipped with push buttons. The pushbuttons are actuated by pushbuttons or shifters, which are held by springs in the neutral position or returned to the neutral position. By pressing the push button, a signal for an electric motor is generated, which moves, for example, the derailleur or the derailleur of a derailleur. The electronic switches for bicycles for switching electronic or electromechanical bicycle transmissions such as multi-speed hubs or derailleurs are also known from the prior art with two push buttons. To switch an electronic or electromechanical element such as rear derailleur, front derailleur or gearbox typically requires a minimum of two pushbuttons. By actuating the first push-button, the element moves in one direction and, by actuating the second pushbutton, the element moves in the other direction opposite to the first one. If a bicycle is equipped with derailleur and derailleur, it needs two switches, each with two push buttons, which are usually attached to the bicycle handlebar. A switch is typically mounted in the grip area of the right hand and the other switch in the grip area of the left hand. Because the rear derailleur is often operated as the derailleur and switch with only one push button are known. These are often mounted in addition, with a switch in the handle area of the right hand and the second switch are mounted in the grip area of the left hand. In this way, switches are provided which can move the element to be moved only in one direction. If the element to be moved is a derailleur, it is possible, for example, to shift to a larger sprocket with the right hand and a smaller sprocket with the left hand.

The known pushbuttons are sensitive to water, dirt and dust and are mechanically stressed, so their life is limited. Water, dirt and dustproof pushbuttons are comparatively expensive. Since these switches manufactured with the corresponding electrical components are elaborately constructed, they are expensive to procure or expensive to manufacture.

Such shakers are for example! from EP 1 958 862 A2. A lever-operated switch for mounting on a handlebar of a motorcycle or snowmobile comprises a housing having an annular part mounted on the handlebar, the latter comprising pressure switches. The pressure switches are coupled to lever elements, which can be transferred via permanent magnets in a rest position and via which a micro-switch is actuated. Known further from the prior art rotary handle switch for bicycles, which are mounted in the grip area of a handlebar tube of a handlebar. These consist of a fixed housing connected to a handlebar and a second rotatable housing, a rotary member which contains a cable coil. By turning the rotary member by hand, the cable is wound up or unwound, whereby a derailleur or a derailleur is operated.

Such a rotary handle switch is disclosed, for example, by US 8,402,664 B1. This relates to a control device for a bicycle, in which magnets are used to generate an input for a control device. The switching device which can be arranged on a straight bicycle handlebar comprises a rotating part which comprises a magnetic element and a part which is fixedly arranged to the handlebar and which likewise comprises magnets. The device further comprises a sensor for detecting the magnetic field of one of the plurality of magnets. The rotational positions are defined by two intermeshing, coaxial gears with axially aligned teeth.

The US 2004/02 16550 A I further discloses a throttle grip for a motorcycle handlebar, in which a rotation of the throttle grip is determined by means of a Hall sensor. The restoring force is provided by a spring.

The known switches all have the disadvantage that a maximum of two pushbuttons can be used, otherwise the switches are too big and can not be ergonomically mounted on the handlebars. In addition, switches with more than two push buttons confusing and could no longer be operated intuitively. In addition, pushbuttons are dirt, dust and wasserempfindüch and must be carefully sealed or the switch must be designed consuming, which can be expensive and less robust. The known Drehg iffschalter have the disadvantage that they can be implemented only with great effort as electronic switches for electronic circuits. The twist grip switches are mechanically stressed, exposed to water, dirt and dust and thus prone to defects. The rotary element or control element is typically not sufficiently defined and precisely movable. Often leaves the feel of the rotary element to be desired, especially if they are not worked well enough, it can lead to unwanted switching operations or the scarf tvorgä ^' nge can not be performed precisely and promptly. Because of these high demands, rotary handle switches for electronic circuits are either barely built or very expensive. Presentation of the invention

The object of the invention is to provide the aforementioned technical field associated electronic switch, which are simple in construction, robust in operation and inexpensive to manufacture.

The solution of the problem is defined by the features of claim 1. According to the invention, the switching element in the first switching position can be detected by means of a proximity switch and the switching element can be transferred from the first switching position by means of magnetic force in the rest position.

By realizing the restoring force as a magnetic force with the simultaneous use of proximity switches, which are influenced by the Schaitteil, particularly simple, robust, shift-proof, intuitively operable and cost-effective electronic switches with two or more, for example four, switch positions can be realized. Hereinafter, these switches are referred to inter alia as a rotary handle switch or four-position switch. As proximity switches, also referred to as proximity switches or proximity switches, inductive proximity switches, capacitive proximity switches, magnetic proximity switches, optical proximity switches, ultrasonic proximity switches, electromagnetic proximity switches and other proximity switches known to those skilled in the art may be used.

In a preferred variant, magnetic proximity switches, such as reed switches, reed contacts, also referred to as reed relays, or Hall sensors are used. These magnetic proximity switches are inexpensive to procure and robust in operation. In a particularly preferred variant reed switches, which are open without agneteinwirkung and close by magnet action, used as a proximity switch. Another particular advantage is that a provided for the reed switch magnet can be used simultaneously for the transfer of the switching element from the switching position to the neutral position. This allows a particularly cost-effective switch can be achieved because components can be saved. In variants, the switching element for the return of the switching element from a switching position to the neutral position and for the activation of a reed switch also have separate magnets.

Alternatively, however, it is also possible to use the above-mentioned proximity switches or further proximity switches known to the person skilled in the art. The restoring force achieved with magnetic force, as well as the detection of a switching position with a proximity switch are characterized by the contactless mode of action. The magnetic return of the switching element only requires a mechanical mobility of the switching element. In particular, this makes it possible to dispense with mechanically prone return mechanisms with, for example, elastic elements such as springs and the like, so that a robust construction of the switch is achieved. Due to the choice of a proximity switch can be dispensed with prone mechanical parts as known in commercial switches. The use of a proximity switch thus also requires in addition to the movable switching element no other mechanical parts, such as electronic pressure switch and the like. In combination, a synergetic effect is now achieved, since in addition to the movement of the switching element itself, no further mechanically moving parts such as springs or switches must be provided, which could influence the robust operation of the switch. As a result of the design according to the invention, the switching element can thus be made water and gas tight in a particularly simple manner, for example. This opens up a wide range of applications for the Schaker in demanding work areas, for example in environments with flammable (eg gasoline, flammable gases, etc.) or aggressive substances (eg acids, bases, solvents, etc.) and the like. Through the contactless return to the neutral position or rest position and the contactless detection of the switching position and possibly additional detection of the rest position can thus be provided a switch, which may be provided with a protective sheath and so gas- respectively fluid-tight and, depending on the choice of material, resistant to arbitrary Media can be trained. For this purpose, the fixed part and the switching element can be completely enclosed separately with a protective layer (eg plasticized, painted or otherwise protected), without having to include a movable element under the protective layer. Such switches are therefore characterized by the simple and inexpensive construction, since they essentially do without sealing element or without tight connections between relatively moving parts. Particularly advantageously, the switch is used in a handlebar of a bicycle, electric bicycle, motorcycle or the like. Particularly preferred switches are mounted on classic road handlebars, triathlon handlebars, Zeitfahrradlenkern, Mountainbikelenkern, straight or curved handlebars for everyday bicycles and electric bicycles. However, it is clear to those skilled in the art that such switches are also suitable for electrical appliances, for example in construction, such as motor saws, manual mixers for concrete, drills, etc. Furthermore, such switches can also be used in vehicles, for example on a steering wheel of a car, a forklift or on a control stick of an aircraft, helicopter, excavator, crane, a lathe, etc. A switch of this kind can also be used as a switching element for an electrical device, such as a Stereo system, a light switch, a mixer, etc. be formed. Furthermore, such switches can also be used in industry for the operation of pumps, processing tools, mills, conveyor belts, etc. The person skilled in any other possible applications of the inventive switch are known. In a particularly advantageous embodiment of the invention, the switch is designed as a four-position switch. The four positions can be achieved in different ways. For example, a toggle switch which can be tilted in four spatial directions can be used. Further, a rotary switch can be used, which can be rotated in four positions (for example, at a distance of 90 °). Further, a rotary switch can be used, softer both axially displaced and can be rotated. Specific embodiments of the four-shift position estimator will be discussed in more detail below.

In variants, however, the switch can also have more or less than four switching positions, for example two, three, five, six etc. rotary switches

Preferably, the switching element is formed as a rotary switching element, starting from the rest position, the first switching position by rotation of the rotary switching element in a first Drehn ^' ment about an axis of rotation is reached and wherein the rest position, starting from the first switching position by a rotation of the rotary switch in a second to the first opposite direction of rotation about the axis of rotation can be converted by magnetic force. The rotary switching element is preferably a component substantially rotationally symmetrical about the axis of rotation. The rotary switching element may for example have the shape of a circular cylinder, wherein it preferably has a corrugation or indentations on the shell side for a better feel. Similar rotary switching elements are known for example in amplifiers of stereos. In variants, the rotary switching element but also have a different shape, for example rectangular. Rotary switching elements in the form of elongated rectangles are known, for example, in light switches in industrial or outdoor use. In variants, the switching element can also be designed as a rotary switching element with only one switching position. Furthermore, the switching element can also be designed as a tilting switching element (see below), as a pushbutton switch or other switching elements known to the person skilled in the art. The rotary handle switch for electronic circuit has the advantages that it is simple and robust and preferably has a good feel of the rotary member or the rotary switching element (rotary member and rotary switching element are used synonymously below) on. This allows further precise and timely switching operations are triggered. Next, the rotary handle switch with inexpensive electrical components can be built and is easy and inexpensive to manufacture.

Preferably, the rotary member or the rotary switching element is held by magnetic force in the neutral position or returned to the neutral position during rotation in the switching positions. When the rotary switch element is rotated to the shift positions, the proximity switch responds to the rotary switch element. By realizing the restoring force as a magnetic force with the simultaneous use of proximity switches, which are influenced by the rotating part, particularly simple, robust, shift-proof and cost-effective electronic rotary handle switch for switching electronic bicycle transmissions such as multi-speed hubs or derailleurs can be realized. The provision of the rotary member in the neutral position is also here not a classic mechanical element, such as a torsion spring, a tension spring or the like, but in turn on magnetic effect. The magnetic effect has the advantage that no mechanical elements such as springs or resilient elements are required, which are sensitive to dust and dirt. The realization of the rotary handle switch with magnetic force also has the advantage that the rotary member is well fixed in the neutral position by the maximum attraction. Bumps and vibrations do not cause the rotating part to move causing unpleasant rattling noises. This is in the realization of a restoring force by springs or resilient elements like the case because in the Neutral position, the springs have a little or no force effect, which stabilize or fix the moving part. The same advantages may also arise with other switches, which are held in the neutral position by magnetic force, such as a toggle switch (see below). With the Rückstei / force as a magnetic force rotary handle switch can be realized with excellent feel, because the magnetic effect in the neutral position is greatest and smallest in the switching position, must be used when pressing the Drehgriffschaiter to overcome the neutral position, the greatest force, which then, the farther the rotating part rotates, decreases sharply until the rotating part strikes in a stop point. This behavior causes the actuator of the rotary handle switch to receive clear feedback when the rotary member reaches the stop point. In classic springs or springy elements, the force is reversed. In the neutral position, a spring has the smallest force and the greatest force in the shift position. As a result, in the neutral position, an actuating element often has to be additionally stabilized or fixed in order to create a pressure point or the impact point must be specially designed so that it is clearly noticeable. These properties also result in a to below explained in more detail toggle switch in an analogous manner.

Proximity switches respond to approach, i. non-contact without direct contact. They are not mechanically stressed and have a very long service life.

The combination of magnetic force and proximity switch resetting enables extremely robust and long-lasting rotary handle switches to be realized. In this way, Drehgriffschaiter realized are not dust, water or dirt sensitive and therefore need not be laboriously protected. Therefore, very small, compact and aesthetic Drehgriffschaiter can be built. In addition, the so-designed Drehgriffschaiter are stabif and robust against the effects caused by falls of the bicycle.

In addition, magnets and proximity switches are devices that are inexpensive to procure, especially because they react without contact. Furthermore, cost-effective, durable and low-maintenance rotary handle switches can be produced with such proximity switches.

The magnets are preferably commercially available permanent magnets or permanent magnets. These usually consist of metallic alloys of iron, nickel, aluminum with additives of cobalt, manganese and copper, or with additions of barium, or strontium hexaferrite. Furthermore, magnets made of bismanol, that is, of iron, bismuth and manganese can be used. However, preference is given to using strong magnets made of samarium cobaft or neodymium iron ferrule, in particular for the production of higher-quality rotary grip switches.

The twist grip switch can be mounted on classic road handlebars, triathlon handlebars, time handlebars, mountain bike core, straight or curved handlebars for everyday bikes and electric bicycles. The rotary handle switch is preferably mounted in the grip region of a handlebar tube of a handlebar and is used for switching electronic bicycle transmissions such as multi-speed hubs or derailleurs.

Alternatively, the rotary handle switch can also be mounted at other locations than in the grip area of a handlebar tube of a handlebar. In principle, a rotary handle switch can be designed such that it can be attached to any point on a bicycle which can be reached with the hands.

In a preferred variant of the rotary handle switch is integrated in the brake lever for mounting on classic curved road handlebars. In this way, a rotary handle switch brake lever unit is provided, which is fastened in the bow of a classically curved road handlebar. In this preferred variant, the brake handle acts as a fixed housing.

Alternatively, a consumer other than an electronic bicycle transmission can be operated with a twist grip switch. It is particularly suitable consumers with an on / off function or consumers, which can be regulated in stages and be operated electrically. Suitable consumers are light, horn, connecting an electric motor, control of an electric motor, etc.

The rotary handle switch is preferably made of a connected to a handlebar or a support rod fixed housing and from an axially fixed to this housing fixed second housing, a rotating part, wherein this rotary part is manually rotatable. The rotary member is preferably formed as a rotary handle. The rotary member may be encapsulated with a rubber-elastic material, resulting in a variety of design options as a rotary handle. The rotary member is preferably rotatable in a first and in a, the first opposite, second switching position.

In a preferred variant, the fixed housing is constructed such that the rotary part can be pushed on and that the stationary housing forms a bearing point for the rotary part.

Preferably, a magnet is firmly anchored in the stationary housing. The field lines of the magnet preferably extend axially to the rotary handle switch. The second hand twistable Drehtei! preferably includes a second magnet, wherein in the neutral position, the two magnets are opposed to opposite poles and there is an attraction force between the two magnets. The rotary member is preferably fixed by the magnetic force on the fixed housing.

While in the preferred embodiment, both the fixed housing and the tappet comprise a magnet, in other embodiments it may be sufficient to provide only one magnet and one magnetic element. Further, other pairs of magnetic elements may be provided, wherein a first magnet with the fixed part and a second magnet are connected to the rotary switching element, wherein the two magnets are aligned so that they face each other in a switching position with the same poles. This will be in the switching position reaches an increased restoring force. Next can thus be overcome even a larger switching path. However, it should be noted that these magnets do not adversely affect a trained as a reed switch proximity switch. In variants, it is also possible to provide exactly one pair of magnets for providing a restoring force from a switching position.

Preferably, the distance of the two magnets in the neutral position is significantly smaller than in the first or second switching position. This optimum force effect is achieved and the rotary handle switch can be kept compact. By turning the rotary part by hand, the magnet anchored in the rotary part is correspondingly deflected. The rotary member may preferably be rotated up to a defined stop. The stop is preferably selected so that when you release the rotating part in the switching position, the Drehtei! is returned to the neutral position by the attraction of the anchored in the stationary housing magnet.

If the rotating part is in the stop position in the first switching position, the magnet anchored therein has the maximum distance to the anchored magnet in the stationary housing. In the first switching position, a proximity switch is now positioned so that it reacts reliably. That is, in the first switching position, the distance of the magnet in the rotating part to the proximity switch is the smallest. Now, when the rotary part is released from the hand, the rotating part rotates due to the attraction of the anchored magnet in the stationary housing in the neutral position. The distance of the magnet in the rotating part to the proximity switch is greater, the force of the magnet on the proximity switch decreases and the proximity switch goes back to its position, which he has no magnetic force. In the neutral position, the magnetic force of the magnet in the rotating part and the magnetic force of the anchored magnet in the fixed housing are too small for the proximity switches to react. In the second position, a proximity switch is mounted analogously to the first switching position. The reed switches are preferably dimensioned and positioned such that in the neutral position of the rotary member they are exposed to a too small magnetic field than they would close. That is, while the rotating part is in the neutral position, the reed switch is open and no current flows. If the rotary part is rotated to the stop of the first switching position, the magnet in the rotary part approaches the corresponding reed switch, which is positioned near the first switching position, the magnetic field increases, the reed switch closes and a current flows. The same happens when the rotary member is rotated to the second switching position. The reed switch, which is close to the second switching position, closes and a current flows. This power can be consumed directly by the consumer. By closing the reed switch but only one signal can be output, which is evaluated by a higher-level control. A higher level controller may be, for example, a bicycle computer.

The person skilled in the art is still aware of other higher-level controllers. In the rotary handle switch, for example, induction or piezo elements can be used. These electrical components can be used for batteryless rotary handle switch. In this case, the signal is transmitted by radio. By induction or piezoelectric elements, the energy required for this is made available.

Preferably, the axis of rotation is coaxial with a circular cylindrical portion of a bicycle part, in particular oriented to a portion of a steering tube. Thus, the rotary switching element can be mounted coaxially with the steering tube. The Drehschalteement can thus be particularly elegantly integrated into the bicycle handlebars, since the rotary switching element can be regarded as a kind of part of the bicycle handlebars. In a triathlon handlebar, the rotary switching element may be arranged, for example, in the end region of the steering tube. In a straight handlebar, the rotary switching element can also be arranged between the handlebar grips, preferably immediately adjacent to the handlebar grips. For mounting the rotary switch element in the end region of the handlebar tube, the switch preferably has a fixed area, which can be pushed into the handlebar tube, pushed over the steering tube. Next, the fixed area also have a circular ring groove into which the steering tube can be inserted.

If the switching element is designed as a toggle switch, the pivot axis of the toggle switch is preferably oriented at right angles to the axis of the steering tube section. Particularly preferably, the toggle switch is arranged in the end region of the steering tube, wherein the tilt lever is aligned axially in the rest position to the steering tube section.

In variants, the axis of rotation can also be oriented elsewhere, for example at right angles to an axis of a steering tube.

Preferably, starting from the rest position, a second shift position can be achieved by a rotation of the rotary switching element in the second rotational direction, wherein the rest position between the first shift position and the second shift position and wherein in particular the rotary switching element from the second switching position by magnetic force in the rest position can be transferred.

In variants, the switch can also be designed such that the second switching position can be reached starting from the first switching position by a rotation in the first direction of rotation. Thus, switching sequences can be defined in an advantageous manner, which represent, for example, the switching positions of a derailleur, a derailleur or a light setting (high and low beam). In further variants, more than two switching positions can be provided, in particular, for example, when used for a derailleur.

Preferably, the rotary switching element is displaceable along a longitudinal direction of the axis of rotation between a first stop position and a second Anschfagposition, wherein within the first stop position, the first switching position and the second switching position can be achieved by a rotation of the rotary switching element about the axis of rotation. This can be achieved in a simple manner further switching positions. The first and the second shift position may represent, for example, the derailleur and the derailleur of the derailleur, while in a rotation of the rotary switching element in the one direction of rotation, for example, the first direction, is switched up and switched in the other direction down. A Movement of the rotary switching element in the longitudinal direction of the axis of rotation would thus correspond to a switching between the derailleur and the rear derailleur, while a rotation of the rotary switching element about the axis of rotation corresponds to a Hochschatten respectively down switching. In variants, more than two positions in the longitudinal direction may be provided, wherein the third, etc., longitudinal position are preferably provided between the two stop positions. In this case, it may be of advantage if a latching device or a holding device can respectively lock the rotary switching element in a longitudinal position - this in turn can be achieved by means of magnetic force. Alternatively, it is also possible to dispense with the stop positions.

Preferably, the rotary switching element is traceable from the second stop position to the first stop position by means of magnetic force. Thus, the rest position is preferably provided in the first stop position. The return of the rotary switching element from the second stop position has the advantage that the rotary shaft element is in each case in the same rest position. This is particularly advantageous when riding a bicycle, since when gripping the rotary switching element this is defined in each case and can be operated so accurately. The return by magnetic force in turn has the advantage that no vulnerable elements such as springs and the like must be used, which can affect the robust operation.

In variants, two rest positions can be provided, which are each in a stop position, so that there is no return of the rotary switching element in the other stop position of the one stop position.

Preferably, the second stop position forms a fifth switching position. This can be achieved with the rotary switching element arranged in a T-shape three switching positions. More preferably, however, more than three switching positions are achieved.

The rotary switching element is particularly preferably in the second stop position by means of a rotation of the rotary switching element in the first direction of rotation in a third switching position and by means of a rotation in the second direction of rotation in a fourth Switching position can be transferred. This can be achieved with the rotary switching element four switching positions.

In variants, the switch may also be provided with more or less than four shift positions. Preferably, a movement space between the DrehschaJteJement and the fixed element is determined by a slotted guide. Thus, in a particularly simple manner, the movement of the rotary switching element on the one hand limited and on the other hand also out. This achieves a particularly simple operation of the switch. In variants can also be dispensed with a sliding guide.

Preferably, the fixed element comprises a guided in a gate of the rotary switching element pin. Thus, the backdrop can be formed in a simple manner on the rotary switching element. If the switch is mounted on a steering tube end, the rotary switching element may be formed substantially as a circular cylindrical cap, wherein in the lateral surface of the slotted guide is cut out. For a particularly cost-constructed slotted guide is achieved.

Alternatively, the rotary switching element may include the pin, which is guided in a backdrop of the fixed element.

Preferably, the magnetic force and the scenery are coordinated so that the rotary switching element from each switching position due to the magnetic force in the rest position is traceable. For a switch is achieved, which is particularly easy to use, since the rotary switching element is always in the same rest position. Such a design can be achieved, for example, that between the rest posi ^' tion and the third and the fourth shift position, the backdrop forms a ramp towards the rest position.

In variants, it may be advantageous if the four-position switch is designed such that in the two stop positions each have a separate rest position is provided. This training is particularly advantageous if in the application longer sequences are performed in each case a specific stop position, that is, if, for example, in certain sections more likely to work with the derailleur and in other sections with the rear derailleur, in this case it can Be advantageous if the rotary switch element can be held in both stop positions.

Preferably, the groove of the gate has a shape of a double-T with a first transverse groove and a second transverse groove parallel to the first transverse groove and a connecting groove connecting the two grooves. This backdrop form ideally reflects the four switching positions.

In variants, the backdrop may also have a square or rectangular shape, which is freely movable over the pin of the fixed element.

Preferably, end regions of the first transverse groove form the first and second damper positions, and end regions of the second transverse groove form the third and fourth switch positions. Preferably, the connecting groove widens in the direction of the second transverse groove. The widening transverse groove has the advantage that the rotary switching element located in the third or fourth switching position can be returned to the rest position in a ramp-like manner.

In variants, the widening transverse groove can also be dispensed with. The scenery may otherwise have a waisted shape, for example, an hourglass-like shape.

toggle switch

In a further preferred embodiment, the switching element is designed as a toggle switch. This embodiment has the additional advantage over the rotary switch, in particular, that a toggle switch can already be easily operated with just one finger. In principle, the rotary switch can be operated with a finger, but typically the rotary switching element for the switching operation is gripped with two fingers. The training as toggle switch is further particularly advantageous due to the simple design. Preferably, the toggle switch comprises a lever arm, which is pivotable about a pivot axis, wherein the lever arm is formed on one side of the pivot axis as an actuating element and on the opposite side of the pivot axis comprises a magnetic element, via which the toggle switch can be held in a neutral position. In variants, the switching element can also be designed as a rotary switch, as stated above. Next, the switching element can also be designed as a slide switch, wherein a switching element can be performed in a linear guide.

Preferably, a separate reed switch is activated in the fixed part with the magnet of the toggle switch in each switching position. Thus, the magnet can be used in the toggle switch after a switching both for the adoption of the neutral position and during the switching operation to activate the reed switch.

In variants, instead of a reed switch and another proximity switch may be provided. Furthermore, the toggle switch can also have separate magnets for returning the toggle switch from a switching position to the neutral position and for activating a reed switch.

Preferably, the toggle switch on four switching position, which lie in particular in distal ends of a cross shape, wherein the neutral position is arranged centrally to the cross shape. This achieves a particularly ergonomic four-position switch. In variants, the toggle switch can also have only two, three or more than four switching positions.

Preferably, the fixed element is designed for receiving in a steering tube, that the toggle switch oriented in the neutral position coaxial with the steering tube. The handlebar is particularly preferably one with a pipe section which is aligned in the direction of travel of the front wheel, for example a triathlon handlebar. In this case, in the grip position, the index finger is automatically at the front end of the steering tube to which the toggle switch is attached. An actuation of the toggle switch is done in a particularly ergonomic manner. Of the Toggle switch can also be mounted on other links or other parts of the bicycle, but which are preferably reachable during driving by hand.

In variants of the toggle switch but can also be used elsewhere. The toggle switch can be used due to the use of magnets to return the switch to the neutral position and due to the use of proximity switches in the same areas as the twist grip switch. While the switches are preferably used in bicycles, they can also be provided in other areas. Toggle switches are used in many different areas - the present toggle switch is suitable for example for demanding environments, such as for the control of construction equipment (eg excavators, circular saw, etc.), industrial equipment (eg control box for equipment in the chemical industry) but also for different motor vehicles (eg motorcycle, car, helicopter, aircraft, etc.), household appliances (eg mixers, cutting machines, electric stove, etc.) or leisure electronics (eg remote control, amplifiers, etc.). The person skilled in any other fields of application are known.

In principle, only electronic switches for bicycles with a function limited to two switching positions are known from the prior art. These are used for switching electronic or electro-mechanical bicycle transmissions such as multi-speed hubs or derailleurs. These known switches do not provide any additional functions for switching or regulating other consumers, such as switching on / off the humidification, controlling an electric motor, operating a horn, switching both the derailleur and the derailleur with the same switch, etc. The switches offer no added benefit in this regard and are exclusively capable of switching electronic or electro-mechanical bicycle transmissions with two functions, typically up and down shifting.

In such a switch, in particular for switching electronic or electromechanical bicycle transmissions such as multi-speed hubs or derailleurs, which can be moved between a neutral position and four shift positions, the RückstelJkraft is preferably designed as a magnetic force and in the switching positions Proximity switches are mounted, which respond to the located in one of the four switching positions switching part.

Preferably, magnetic proximity switches are used in the rotary handle switch. Reed switches are particularly preferably used in the rotary handle switch. Preferably, piezo elements are additionally used in the switch in order to enable wireless operation. About the piezo elements enough energy, in a switching operation are generated to the Schalttnformati ^'on kabeilos, for example via radio, infrared, etc. to the rear derailleur, but also to send to another facility or the derailleur.

Such an electronic switch, in particular for electronic or electromechanical bicycle transmissions such as multi-speed hubs or derailleurs with preferably four switching functions, can be constructed simply and robustly. Furthermore, the operation is intuitive, as toggle switches are well known from daily life. Toggle switches can simply be designed such that they have a good feel and can trigger switching operations precisely and in a timely manner. Toggle switches include inexpensive electrical components or are simple and inexpensive to manufacture. The switching member is held in the neutral position by magnetic force, or returned to the neutral position after being shifted to one of the four shift positions, with proximity switches responding to the shift member which is moved to one of the four shift positions. It is preferably a switch, in particular for bicycles, in which a switching part between a neutral position and four switching position is movable, wherein the switching part is acted upon in the switching positions with a restoring force, which returns the switching part in the neutral position and proximity switch on the switching part respond, which is moved to one of the switching positions. Because four shift positions can be covered with a four shift position switch, only one switch can be mounted in a bicycle in which, for example, a derailleur and a derailleur need to be moved. A four-position switch covers all functions. Or it can, as in a further preferred arrangement, mounted two four-position switches on the handlebars A four-position switch in the grip area of the right hand and a second four-position switch in the grip area of the left hand, in this case, eight switching positions are available. That is, in the case of a bicycle with derailleur and derailleur four switching positions are available for switching or controlling other consumers.

As additional consumers or in other words as an additional function or as a sole function, which can be controlled with the four-position switch, the following additional functions come into consideration. The additional functions or expansions are subdivided into the following groupings: Additional functions for the lighting: turn signals, lighting (on / off, regulation of the light intensity), warning light (indicate danger on the road), emergency light.

Additional bicycle functions: suspension adjustments (switch to different modes that regulate the combination of spring systems such as suspension fork and damper), control of suspension forks (on / off, lowering / raising, adjustment of spring characteristics), control of dampers (on / off, setting damper characteristics), lowering / raising the seat post electric motor drive (on / off, regulation of the support), control of the chain guide (always optimal chain line between derailleur and derailleur), theft protection, movement and position measurement of the fork, vibration measurement of the bicycle, measurement of the road surface, Position measurement of the wheels.

Peripheral devices: additional functions; Control and regulation of: Velocomputers, smartphones, movie cameras, cameras, power meters, cadence gauges, GPS.

Acoustic additional functions: horn, warning signals, voice radio (on / off or regulation of the contact to accompanying vehicle or companion / passenger),

Intercoms.

Trainings Additional functions: Switching on special modes such as constant cadence (automatic switching). The person skilled in the art is aware of other consumers, extensions or additional functions which can be regulated, controlled or switched on / off.

The return of the moving switching part, such as shift lever or rotary handle or the like from the four shift positions to the neutral position does not take place via a classical mechanical element, such as a torsion spring, a tension spring or the like, but via magnetic action. The magnetic effect has the advantage that no mechanical elements such as springs or resilient elements are required, which are sensitive to dust and dirt. The realization of a four-position switch with magnetic force also has the advantage that the moving Schaltteii is well fixed in the neutral position by the maximum attraction. Bumps and shocks are less likely to cause the movable switch member to move, causing unpleasant rattling noises or misfires. This is in the realization of a restoring force by springs or resilient elements like the case, because in the neutral position, the springs have little or no force effect, which stabilize or fix the movable part.

With the restoring force as a magnetic force can be four-position switch with excellent feel, because the magnetic effect in the neutral position and the smallest in the respective switching position is smallest, when pressing the switching part to overcome the neutral position, the greatest force must be spent, but then, depending further moves the movable switching member, decreases sharply until the movable switching member strikes in a stop point. This behavior causes the actuator of the four-position switch to receive clear feedback when the movable switch reaches the snub point. In classic springs or springy elements, the force is reversed. In the neutral position a spring has the smallest force effect and in the shift position the greatest force effect. As a result, in the neutral position, an actuating element, such as a switching part, often additionally needs to be stabilized or fixed in order to create a pressure point or the point of attachment must be specially designed so that it is clearly noticeable.

Proximity switches react to approach, ie without direct contact without contact. They are not mechanically stressed and have a very long service life. In the combination of resetting by magnetic force and detection of the switching part by proximity switches extremely robust and durable four-position switches can be realized. In this way, realized four-position switches are not dust, water or dirt sensitive and therefore need not be laboriously protected. Therefore, very small, compact and aesthetic four-position switches can be built. In addition, the so constructed four-position switches are stable and robust against the effects caused by falls of the bicycle.

In addition, magnets and proximity switches are components that can be procured inexpensively and because they respond without contact, cost-effective, durable and low-maintenance four-position switches can be made.

The magnets are preferably commercially available permanent magnets or permanent magnets. These usually consist of metallic alloys of iron, nickel, aluminum with additives of cobalt, manganese and copper, or with additions of barium, or strontium hexaferrite. Next magnets also from Bs can ^'smanol, that ^is' sst be used iron, bismuth and manganese. However, strong magnets made of samarium cobalt or neodymium-iron-boron are preferably used, in particular for higher-quality four-position switches,

As a proximity switch, also called proximity switch or proximity switch, inductive proximity switches, capacitive proximity switches, magnetic proximity switches, optical proximity switches, ultrasonic proximity switches or electromagnetic proximity switches can be used.

In a fixed housing, ie a housing which is anchored to a handlebar rod or handlebar tube of a handlebar so as to be slip-proof and rotationally fixed, a magnet is anchored. A manually movable switching member includes a second magnet fixedly secured therein. The manually movable switching member is preferably movably mounted or attached to the stationary housing. This movable attachment of the switching part may correspond in form or function of a plain bearing, spherical plain bearings, ball bearings or heat / z / ager. The movable shaft part can also be attached to other parts such as the handlebar tube of a handlebar. The person skilled in the art is aware of other types and locations, such as where the movable switching part can be mounted or applied.

In a preferred variant, recesses or guides are incorporated in the stationary housing. These recesses or guides safely guide the movable switching part into one of the four switching positions, provide the switching part with a secure stop and hold in the switching positions, and in turn safely return it to the neutral position.

In the neutral position, the magnets of the fixed housing and the switching part are opposite to opposite poles and an attraction force exists between the two magnets. The switching part is easily fixed by the magnetic force on the fixed housing. In a preferred embodiment, magnets may also be provided, which face each other in a switching position with the same poles in order to promote a transfer to the neutral position.

Preferably, the distance of the two magnets in the neutral position is significantly smaller than in the four switching positions. Thus, an optimal force effect is achieved and the four-position switch can be kept compact.

The movable switching part is movable so that four positions, so-called switching positions, can be assumed. The switching positions must be selected so that the magnet of the switching part by the attraction of the magnet in the fixed housing, the switching part safely and promptly returned to the neutral position.

Preferably, to increase the deflection of the switching part or the sprung deflection or guidance of the switching part, adjacent to the magnet in the stationary housing or adjacent to the magnet of the switching part, a further magnetic element along the movement path between the SchaStposition and the neutral position is arranged. The magnetic element is preferably made of nickel, iron, cobalt, ferrite or an alloy thereof. Alternatively, the magnetic element may be formed as a permanent magnet, but which has a smaller force on the Magnets of the switching part exerts as the magnet in the fixed housing, so that the switching part does not get caught in the magnetic element.

Proximity switches are placed near the four switch positions and respond to the shift in each of the four shift positions. The proximity switches give a signal to the consumer or to a higher-level controller, such as a bicycle computer.

The person skilled in the art is still aware of other higher-level controllers.

In a preferred variant, magnetic proximity switches, such as reed switches, reed contacts, also referred to as reed relays, or Hall sensors are used. These magnetic proximity switches are inexpensive to procure and robust in operation.

In a particularly preferred variant, reed switches, which are open without magnet action and close by the action of magnets, are used as proximity switches. The reed switches are in the neutral position of the switching part subjected to a too small magnetic field, as they close. That the reed switches are open and no electricity is flowing. If the switching part is moved by hand to the stop in one of the four switching positions, the magnet in the switching part approaches the corresponding reed switch, which is positioned in the vicinity of this switching position, the magnetic field increases, the reed switch closes and a current flows. This power can be consumed directly by the consumer. By closing the reed switch but only one signal can be output, which is evaluated by a higher-level control. When the movable switching part is released again, it moves back into the neutral position by the attractive forces exerted by the magnet in the stationary housing on the magnet in the switching part and the reed switch opened in the respective switching position closes again.

In the four-position switch also induction switch or piezo elements can be used. These electrical components can be for batteryless Four-position switch can be used. In this case, the signal is transmitted by radio. By induction or by piezo elements, the energy required for this is made available.

The four-position switch can be mounted on classic road handlebars, triathlon handlebars, time-trial handlebars, ountainbike, straight or curved handlebars for everyday bicycles, and electric bicycles. The four-position switch is preferably mounted in the grip area of a handlebar tube of a handlebar.

Alternatively, the four-position switch can also be mounted in other places than in the grip area, a handlebar tube of a handlebar. It can be built a four-position switch, which can be attached anywhere on the bike, which is accessible with your hands. In a preferred variant, the four-position switch is integrated in the brake lever for mounting on classically curved road handlebars. In this way, a four-position shift lever brake lever unit is provided, which is fixed in the bow of a classically curved road handlebar. In this preferred variant, the brake handle acts as a fixed housing.

Instead of the four switching positions, a four-position switch can also have only three or two switching positions, which are equipped with proximity switches.

In another preferred embodiment, data representing a switching operation is transmitted wirelessly. For this purpose, the switch preferably comprises a radio module with an antenna or another transmitter known to those skilled in the art. The energy required for the radio module is preferably provided by the switch itself, for example via piezoelectric elements or by induction. In the latter case, for example, a coil can be coaxially arranged in a rotary switch, in which, upon rotation of the rotary switch, a magnet is moved in the coil, thus inducing a current. Alternatively, a battery for the power supply may be provided. Preferably, the antenna is connected via a CPU or a processor with the various consumers and / or with a provider.

In variants, the data transmission can also be done via cable. From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Figure 1 shows a schematic representation of an aerobar, as is typical of time bicycles and triathlon, with two mounted rotary handle switches.

The two rotary handle switches 1 are switches as they are preferably mounted on aerobars 10, which are used for time or triathlon bikes. The rotary handle switch 1 are in the grip area of the Armauflagenstangen 1 1 mounted and can thus be operated in an aerodynamic posture. The aerobar 10 is connected by the stem 12 to the steerer of a bicycle fork (not shown).

2 shows a schematic representation of a ountainbikelenkers with two mounted rotary handle switches 1. 1.

The two rotary handle switches 1. 1 are switches as they are preferably mounted on Mountainbikelenkem 20. The Drehgriffsch age be mounted between the brake handles 21 and the handlebar ends. The Mountainbikelenker 20 is connected by the stem 12 with the steerer tube of a bicycle fork (not shown). FIG. 3a shows a schematic illustration of the upper side of a respective top view of a rotary handle switch 1 in the neutral position.

The rotary handle switch 1 is mounted on the Armauflagenstange 1 1 of an aerobar according to Figure 1. The rotary handle switch 1 consists of a firmly anchored to the Armauflagenstange 1 1 end cap 30, an axially to Armauflagenstange 1 1 rotatable rotary handle 31 and a fixedly anchored to the Armauflagenstange 1 1 fixing ring 32nd

An end cap magnet 33 is anchored in the end cap 30, and a twist grip magnet 34 is anchored in the twist grip 31. The twist grip switch 1 is in the neutral position in the present Figure 3a, the end cap magnet 33 and the twist grip magnet 34 are opposite and are oriented so as to attract each other. The rotary handle 31 is fixed vibration resistant by the attraction of the two magnets. In the neutral position, the twist grip magnet 34 has a minimum clearance with the end cap magnet 33, so that the neutral position is a stable state.

3b shows a diagrammatic representation of the underside of a rotary handle switch in neutral position The rotary handle switch 1 is mounted on the arm support rod 1 1 of an aerobar The rotary handle switch 1 is in the neutral position The end cap 30 has a recess and the rotary handle 31 has a The pin protruding into the recess So it can only be rotated so far until the pin strikes the end cap 30. The recess of the end cap 30 thus serves as a stop for the pin of the rotary handle 3 1. In variants, the end cap 30 may include the pin while the rotary handle 31 includes the recess. FIG. 3c shows a schematic sectional representation of the upper side of a twist grip switch in the neutral position, viewed from the underside.

The end cap 30 is slipped by the fixing screw 35 and rotationally connected to the Armauflagenstange 1 1. The fixing screw 35 is screwed radially into an internal thread of the jacket of the end cap 30. In the end cap 30 two Reedscha! Ter 3ό are poured. The two reed switches 36 are connected by the electric cables 37 to a superordinate controller which controls a bicycle circuit. The twist grip switch 1 is in the neutral position, the end cap magnet 33 and the twist grip magnet 34 are vis-à-vis. The two reed switches 36 are open, the distance to the two magnets is too large, or the magnetic force too small to react. The fixing ring 32 with the Fixiersch robe 35 firmly anchored to the Armaufiagenstange 1 1 and prevents the rotary handle 31 can be removed.

The reed switches are spaced from each other by approximately 30 ° with respect to the axis of rotation of the rotary handle 31. In the neutral position, the end cap magnet 33 lies exactly between the two reed switches 36 and the rotary handle magnet 34 is in the neutral position opposite the end cap magnet 33 and thus also exactly between the two reed switches 36. The end cap magnet 33 is so far away from the reed switches 36 in this orientation, that the latter are not influenced by the Endkappenmagnet 33 or the Drehgriffmagnet 34. A rotation of the rotary handle 31 in one of the two directions of rotation now causes the rotary handle magnet 34 approaches one of the two reed switch 36 and causes a circuit of the reed switch 36.

The rotary handle magnet 34 thus has in the present first embodiment, a dual function - on the one hand, by the magnetic action between the rotary handle magnet 34 and the end cap magnet 33 of the rotary handle 31 from a Switched position each transferred to the neutral position. On the other hand, by the rotary handle magnet 34 and the circuit of the reed switch 36th

Under certain circumstances, this double function can be disadvantageous, in particular if the reed switches 36 and the two magnets 34, 33 are arranged in a small space. In this case, can be triggered by the two magnets 34, 33 faulty circuits. To exclude such problems, it may therefore be advantageous if in a second embodiment, the two magnets 34, 33 are positioned as far away from the reed switch in the neutral position, at an angular distance between the reed switches 36 of 30 °, for example straight in one 165 ° angle (centered on the two reed switches 36, but on the back of the end cap 30).

FIG. 3d shows a schematic sectional representation of the twist grip switch in neutral position, wherein the twist grip switch is shown in the rotation axis. The figure 3d corresponds to the first embodiment.

The two reed switches 36 are cast in the end cap 30 and are within the Armauflagenstange 1 1. The two reed switch 36 have the same distance from the rotary handle magnet 34 which is anchored in the rotary handle 31.

FIG. 3e shows the illustration according to FIG. 3d in the second embodiment. The difference is that a separate magnet 43 is provided for the circuit of the reed switch 36, which is arranged at the same location as the rotary handle magnet 34 in the figure 3d - the latter is now arranged exactly opposite the rotary handle 31. Not apparent in the present Figure 3e as well as in the preceding figure 3d, the end cap magnet 33, which is arranged in the longitudinal direction behind the twist grip magnet 34.

FIG. 4a shows a schematic representation of the upper side of a twist grip switch in a first switching position according to the first and the second embodiment, respectively.

The rotary handle 31 is rotated by hand in the direction of travel to the left. The handle magnet 34 turns away from the fixed end cap magnet 33. 4b shows a schematic representation of the underside of a rotary handle switch in a first switching position according to the first embodiment.

The rotary handle 3 1 is rotated in the direction of travel to the left. The rotary handle 3 1 can be rotated until the pin abuts the edge of the recess in the end cap 30. FIG. 4c shows a schematic sectional view of the upper side of a twist-grip switch in a first switching position, viewed from the underside. This illustration corresponds to the first embodiment. According to the second embodiment, the reed switches would not be apparent since they would be opposite in the other half of the cut. The rotary handle 31 is rotated in the direction of travel to the left. The rotary handle magnet 34 moves in the direction of the reed switch 30 and closes it by the magnetic force. As a result, the signal is given to the higher-level control unit and the circuit switches. If the rotary handle 31 is released again, this rotates back to the neutral position due to the attractive force of the end cap magnet 33 and the reed switch 36 opens again.

Figure 4d shows a schematic sectional view of the rotary handle switch of the first embodiment in a first switching position, wherein the rotary handle switch is shown in the axis of rotation.

The rotary handle 31 is rotated in the direction of travel to the left. The rotary handle magnet 34 moves towards the reed switch 36 and closes it. If the rotary handle 31 is released again, the end cap magnet 33 pulls the rotary handle magnet 34 and thus the rotary handle 3 1 back into the neutral position and the reed switch 36 Opens again.

FIG. 4e shows the illustration according to FIG. 4d, but of the second embodiment, in the first shearing position. In contrast to FIG. 4 d, two magnets 43, 34 are connected to the rotary handle 31, namely the rotary handle magnet 34 for transferring the rotary handle 31 to the neutral position and, opposite, the reed magnet 43 for switching the reed switches 36. FIG. 5a shows a schematic representation of the upper side of a twist-grip switch according to the first and the second embodiment in a second switching position.

The rotary handle 31 is rotated by hand in the direction of travel to the right. The handle magnet 34- rotates away from the fixed end cap magnet 33.

FIG. 5b shows a schematic representation of the underside of a twist-grip switch according to the first and the second embodiment in a second switching position.

The rotary handle 3 1 is rotated in the direction of travel to the right. The rotary handle 31 can be rotated so far until the pin abuts the edge of the recess in the end cap 30.

FIG. 5c shows a schematic sectional illustration of the upper side of a twist grip switch according to the first embodiment in a second switching position, viewed from the underside.

The rotary handle 3 1 is rotated in the direction of travel to the right. The rotary handle magnet 34 moves in the direction of the reed switch 36 and closes it by the magnetic force. As a result, the signal is given to the higher-level control unit and the circuit switches. If the rotary handle 31 is released again, this rotates due to the attraction of the end cap magnet 33 back to the neutral position and the reed switch 36 Opens again.

FIG. 5 d shows a schematic sectional view of the rotary handle switch of the first embodiment in a second switching position, wherein the rotary handle switch is shown in the axis of rotation.

The rotary handle 31 is rotated in the direction of travel to the right. The rotary handle magnet 34 moves towards the reed switch 36 and closes it. If the rotary handle 31 is released again, the end cap magnet 33 pulls the rotary handle magnet 34 and thus the rotary handle 31 back into the neutral position and the reed switch 36 opens again. The second switching position of the second embodiment substantially corresponds to the mirror image of Figure 4e - starting from the figure 3e, the rotary handle 31 would rotate in the clockwise direction instead of in the counterclockwise direction. FIG. 6a shows a schematic sectional view of a third embodiment of the rotary switch in the neutral position viewed from above.

The rotary handle switch 1. 1 is attached to a Mountainbikelenker 20. The rotary handle 31. 1 is in the neutral position. The rotary handle magnet 34.1 is vis-ä-vis of the end cap magnet 33. 1. The end cap 30. 1 is by the fixing screw 35 with the Mountainbikelenker 20 slipping and rotationally connected. In addition to the end cap magnet 33.1 fixed to the end cap 30.1, the two reed switches 36.1 are also firmly embedded in the end cap 30.1. The reed switch 36. 1 are outside the Mountainbikelenkers 20. The rubber grip 38 is mounted on the Mountainbikelenker 20 slipping and rotationally fixed and gives the rotary handle 31. 1 a stop. The rotary handle 31 .1 can be rotated analogously to the rotary handle switch 1. The operation of the Drehgriffschaiters 1. 1 is analogous to the Drehgriffsch age 1. There are two switch positions in which the reed switch 36. 1 close and deliver a signal to a higher-level control, which switches an electronic circuit, and the rotary handle 31. 1 by the Endkappenmagneten 33.1 in the neutral position held or returned to this when the deflected handle 31.1 is released.

A variant of the third Äusführungsform shows the figure 6b. The reed switch 36.1 are in contrast to the embodiment according to Figure 6a not outside the Mountainbikelenkrohrs, but within. The reed switch 36.1 are cast in a pin 50 which is inserted into the steering tube. The pin 50 is fixed by means of the fixing screw 35, which also fixes the end cap 30.1 on the outside of the steering tube through the steering tube. As a result, the end cap magnet 33.1 and the reed switches 36.1 are aligned with each other. This training also has the advantage that on the one hand, the reed switch are better protected and on the other hand, the wiring of the reed switch (if not carried out wirelessly) do not need to be passed through the Lenkrohrwandung.

FIG. 7a shows a schematic sectional representation of a fourth embodiment of the twist grip switch in the neutral position as a side view. The rotary handle 31 .2 is integrated in a rotary handle switch 1 .2, which also includes a Bremshebei 4 1 and so can be used as a rotary handle switch brake lever unit for classic racing bikes. Such brake shift handles are mounted on classic curved road handlebars. The handle body 39 includes the therein firmly anchored handle body magnet 40, the cast reed switch 36.2 and the Bremshebei 41. The rotary handle 31.2 is in the neutral position, the Drehgriffmagnet 34.2 is vis-ä-vis of the handle body magnet 40th The fixing ring 32.2 is by the fixing screw 35.2 with the handle body 39 firmly connected. The rotary handle 31 .2 can be rotated analogously to the rotary handle switch 1. The operation of the rotary handle switch 1 .2 is analogous to the rotary handle switch. 1 There are two switch positions where the reed switch 36.2 close and give a signal to a higher-level control, which switches a circuit, and the rotary handle 31.2 is held by the handle body magnet 40 in the neutral position or returned to this when the deflected rotary handle 31. 2 is released. FIG. 7b shows a schematic representation of a fourth embodiment of the twist grip switch as a side view.

The rotary handle shift lever 1.2 shows the handle body 39, the brake lever 41, the rotary handle 31 .2 and the fixing ring 32.1. On the rotary handle 31 .2 3 handle pins 42 for better twisting of the rotary handle 31.2 are mounted. The rotary handle switch 1, in particular for switching electronic bicycle transmissions such as multi-speed hubs or derailleurs, consists of a rotary handle 31 which is rotatable between a neutral position and two switching positions, wherein the restoring force is formed as a magnetic force and in the switch positions proximity switches are mounted, which on the in react to one of the two switching positions rotary handles.

Preferably, for the twist grip switch 1, an end cap 30, a twist grip 31 and a fixing ring 32 or rubber grip 38 are used as constituents.

Preferably, the rotary handle 31 is axially attached to the end cap 30. More preferably, a magnetic proximity switch is used. Further preferred are additional Piezo elements used to enable battery-free operation. In a further preferred variant, the signals are transmitted wirelessly (via radio, Bluetooth or other techniques known to the person skilled in the art). More preferably, a brake lever 41 and a handle body 39 are components thereof. Four shift position switch

Figure 8 shows a schematic illustration of an aerobar, as is typical of time-bicycles and triathlons, equipped with a first embodiment of the four-position switch and a second embodiment of the four-position switch. In the four-position switch of the first embodiment 101 and the four-position switch of the second embodiment 101. 1 are four-position switches, as they are preferably mounted on aerobars 1 10 of time trial or triathlon. The Vierschaltpos ^{^'it'} ionsscha) ter 101 and 101.1 are mounted in the handle area of the Armauflagenstangen 1 1 1 and can be operated in an aerodynamic posture. For illustration, both embodiments are shown on the same aerobar 1 10. Preferably, an Aerofenker 1 10 is equipped each with only one embodiment. The aerobar 1 10 is connected by the stem 1 12 with the steerer tube of a bicycle fork.

FIG. 9a shows a schematic sectional view of the upper side of a first embodiment of a four-shift position switch, which is mounted axially on a handlebar tube, in the neutral position.

The four-position switch 101 is mounted on the Armauflagenstange 1 1 1 of an aerobar. The end cap 130 is anchored by the fixing screw 1 31 fixed to the Armauflagenstange 1 1 1. On the end cap 130, in turn, the housing 1 33 is screwed to the end cap screws 1 32. As a result, the housing 1 33 anchored slip-proof and rotationally. The end cap 130 and the housing 133 form a hinge bearing for the lever 1 34. The lever 134 is thereby movable in all directions. In the housing 133 of the housing magnet 1 35 and in the lever 134 of the lever magnet 1 36 is firmly anchored. The four-position switch WO is in the neutral position, the case magnet 135 and the lever magnet 136 face each other. The two magnets are aligned so that they attract each other. The lever 134 is fixed vibration resistant by the attraction of the two magnets. In the housing 133, the reed switch 137 are cast. The reed switches 137 are connected to the cables 138 with a higher-level control.

FIG. 9b shows a schematic sectional view of a first embodiment of a four-shift position switch in the neutral position in the direction of the front (travel direction) parallel to the arm support rod.

The housing 133 is fixed inside the Armauflagenstange 1 1 1. The reed switches 137 are cast in the housing 133 and aligned parallel to the arm support rod 1 1 1. The lever magnet 136 and thus the lever 134 are aligned centrally. The lever magnet

136 has the greatest distance to the reed switches 137 in the neutral position. The housing 133 has recesses which securely guide the lever 134 into the respective four switching positions. FIG. 10a shows a schematic sectional representation of the upper side of a first embodiment of a four-position switch, which is mounted axially on a handlebar tube, in a first switching position.

The lever 134 is pressed by hand to the left and finds a stop in the housing 133. The lever magnet 136 has in this switching position the smallest distance to the reed switch 137, which is mounted in this switching position. This reed switch

137 reacts to the magnetic field of the lever magnet 136 and closes. Current flows or a signal is given to a higher-level control. If the lever 134 is released, this is returned by the attraction of the housing magnet 135 back to the neutral position, the magnetic field is smaller and the reed switch 137, which is mounted at this first switching position opens again.

FIG. 10b shows a schematic sectional representation of a first embodiment of a four-shift position switch in a first shift position in the direction of the front (travel direction) parallel to the arm support rod. The lever 1 34 can be pressed to the left until the lever 1 34 abuts with the lifting magnet 136 on the housing 1 33. The distance to the reed switch 137, which is mounted in the first switching position is smallest and the magnetic field strongest and this reed switch 137 closes by. Current flows to the higher level control until the lever 134 is released.

FIG. 11a shows a schematic sectional illustration of the upper side of a first embodiment of a four-position switch, which is mounted axially on a handlebar tube, in a second switching position.

The lever 134 is pressed by hand to the right. The lever magnet 1 36 is deflected and strikes the housing 133. In this position, the lever magnet 1 36 has the shortest distance to the reed switch 137, which is mounted in the second switching position and closes it. Current flows to the higher level control until the lever 134 is released.

Figure 1 1 b shows a schematic sectional view of a first embodiment of a four-position switch in a second switching position in the direction of the front (direction of travel) parallel to the arm support rod.

The lever 134 can be pushed to the right until the lever 1 34 strikes the housing 133 with the lever magnet 136. The distance to the reed switch 137, which is mounted in the second switching position, is the smallest or the magnetic field strongest and this reed switch 1 37 closes thereby. Current flows to the higher-level control until the lever 1 34 is released again.

Figure 12a shows a schematic sectional view of the top of a first embodiment of a four-position switch, which is axially mounted on a handlebar tube, in a third switching position. The lever 134 is pushed down by hand. The lever magnet 1 36 is deflected and strikes the housing 1 33. In this position, the lever magnet 136 has the shortest distance to the reed switch 1 37, which is mounted in the third Schaltposit / ^' on and close this. Current flows to the higher-level control until the lever 134 is released again.

FIG. 1b shows a schematic sectional representation of a first embodiment of a four-shifter position shifter in a third shift position in the direction of view still in front (direction of travel) parallel to the armrest rod.

The lever 134 can be pressed down until the lever 134 with the lever magnet 1 36 abuts the housing 1 33. The distance to the reed switch 137, which is mounted in the third switching position, is the smallest or the magnetic field strongest and this reed switch 137 closes thereby. Current flows to the higher-level control until the lever 1 34 is released again.

FIG. 1 3a shows a schematic sectional illustration of the upper side of a first embodiment of a four-shank position shifter, which is mounted axially on a handlebar tube, in a fourth switching position.

The lever 134 is pushed upwards by hand. The lever magnet 1 36 is deflected and strikes the housing 133. In this position, the lever magnet 136 has the shortest distance to the reed switch 137, which is mounted in the fourth switching position and closes it. Current flows to the higher level control until the lever 134 is released.

FIG. 13b shows a schematic sectional illustration of a first embodiment of a four-shifter position shifter in a fourth shift position in the direction of the front (travel direction) parallel to the arm support rod.

The lever 1 34 can be pushed upwards until the lever 134 strikes the housing 133 with the lever magnet 136. The distance to the reed switch 137, which is mounted in the fourth switching position, is the smallest or the magnetic field strongest and this reed switch 137 closes, current flows to the higher-level control until the lever 1 34 is released. It is also conceivable to equip one of the four-position switches described above only with two positions. In this case, the lever 1 34 would be formed pivotable about a single axis and only two reed switches 137 would be provided. This variant can also be installed in an aerobar 10. In particular, instead of having two different four-position position switches, the aerobar can also be equipped with two such toggle switches with only two positions, for example to operate a derailleur with one and a derailleur with the other. The housing magnet 135 could also be arranged in this case next to the lever 134, whereby a structurally simpler structure would be achieved. Figure 14a shows a schematic sectional view of the underside of a second embodiment of a four-position switch in the neutral position.

The end cap 130.1 is fixed with the fixing screw 1 31 against rotation and slipping on the Armauflagenstange 1 1 1. The rotary handle 1 39 is axially to Armauflagenstange 1 1 1 rotatable. In the rotary handle 1 39, a rotary handle magnet 140 and in the end cap 1 30.1 an end cap magnet 141 is firmly anchored. The Vierschaltpositionsschaiter 10 1. 1 is in the neutral position, the rotary handle magnet 1 0 and the Endkappenmagnet 141 face each other. The two magnets are aligned so that they attract each other. The rotary handle 139 is fixed vibration resistant by the attraction of the two magnets. In the end cap 130. 1, the four reed switches 137. 1 are encapsulated and connected by the cables 38 to a higher-level control. In the present first variant, two reed switches 137. 1 are arranged in a line one behind the other in the longitudinal direction.

FIG. 14b shows a schematic representation of the underside of the second embodiment of a four-position switch in the neutral position. On the rotary handle 1 39, a pin 142 is attached. The end cap 130. 1 has recesses which form the pin 142 stops or lead the pin. In the neutral position of the rotary handle 1 39 and consequently the pin 142 are fixed by the attraction of the two magnets. FIG. 15a shows a schematic sectional view of the underside of the second embodiment of a four-position switch in a first switching position.

The rotary handle 139 is rotated by hand to the right. The rotary handle magnet 140 is deflected maximum and has the smallest distance to the reed switch 1 37.1, which is mounted in this first switching position. The reed switch 1 37. 1 closes by the stronger magnetic field, which starts from the handle magnet 140 in the first switching position and current flows to the higher-level control. If the rotary handle 139 is released, this rotates due to the attraction of the end cap magnet 141 in the neutral position and the reed switch 1 57.1, which is mounted in the first switching position, opens again.

In the present case, with the rotation of the rotary handle 139, the distally arranged reed switches 1 37.1 are actuated.

FIG. 15b shows a schematic representation of the underside of a second embodiment of a four-position switch in a first switching position. The rotary handle 139 can be rotated so far to the right until the pin 142 abuts the edge of the recess of the end cap 1 30. 1.

FIG. 16a shows a schematic sectional representation of the underside of a second embodiment of a four-position switch in a second switching position.

The rotary handle 139 is twisted by hand to the left. The rotary handle magnet 140 is deflected maximum and has the smallest distance to the reed switch 137.1, which is mounted in this second switching position. The reed switch 137.1 closes by the stronger magnetic field, which emanates from the rotary handle magnet 140 in the first switching position and current flows to the higher-level control unit. When the rotary handle 139 is released, it rotates back to the neutral position due to the attraction force of the end cap magnet 141, and the reed switch mounted in the second switch position opens again. FIG. 16b shows a schematic representation of the underside of a second embodiment of a four-position position switch in a second switching position.

The rotary handle 139 is in the second switching position. The rotary handle 139 can be rotated so far to iinks until the pin 142 abuts the edge of the recess of the end cap 130.1.

FIG. 17a shows a schematic sectional view of the underside of the second embodiment of a four-position switch in a third switching position.

The rotary handle 139 is in the third switching position. The rotary handle 139 was turned by hand to the rear and then to the right. The rotary handle 139 is located in the fixing ring 144 a stop. The fixing ring 144 is slidably connected to the fixing screw 1 3 1 and rotationally connected to the Armauflagenstange 1 1 1. The handle magnet 1 0 is deflected maximum and has the smallest distance to Reeds switch 137.1, which is mounted in this third switching position. The ReedsSchaker 137. 1 fights through the stronger magnetic field, which emanates from the rotary handle magnet 140 in this third switching position and current flows to the higher-level control. When the rotary handle 1 39 is released, the rotary handle magnet 140 rotates first in the direction of the magnetic element 143, which is embedded in the Armauflagenstange 1 1 1 and then the rotary handle magnet 140 is attracted by the attraction of the Endkappenmagneten 141 to this. Due to the attractive force of the two magnets, the rotary handle 1 39 is fixed to the end cap 130. 1 in a vibration-proof manner.

Thus, in the figure 17a and the figures described below 17b, 18a and 18b with the rotation of the rotary handle 1 39 in the second axial position, the proximally disposed reed switch 137.1 is actuated.

FIG. 17b shows a schematic representation of the underside of a second embodiment of a four-position switch in a third switching position.

The rotary handle 139 is in the third switching position. The rotary handle 139 can be rotated far enough to the rear and to the right until the pin 142 abuts the edge of the recess of the end cap 130, 1 or the rotary handle 139 strikes against the fixing ring 144. FIG. 18 a shows a schematic sectional representation of the underside of a second embodiment of a four-position switch in a fourth switching position.

The rotary handle 139 is in the fourth switching position. The handle 139 was turned by hand to the rear and anschalte left. The rotary handle 139 is located in the fixing ring 144 a stop. The fixing ring 144 is slidably connected to the fixing screw 131 and rotationally connected to the Armauflagenstange 1 1 1. The twist grip magnet 140 is maximally deflected and has the smallest distance to the reed switch 137.1, which is mounted in this fourth shift position. The reed switch 137.1 closes due to the stronger magnetic field which emanates from the rotary handle magnet 140 in this fourth switching position and current flows to the higher-level control. When the rotation handle 139 is released, the handle magnet 140 rotates first toward the magnetic member 143 embedded in the arm support rod 11, and then the handle magnet 140 is attracted thereto by the attraction force of the end cap magnet 141. Due to the attraction of the two magnets, the rotary handle 139 is fixed to the end cap 130.1 vibration resistant.

FIG. 18b shows a schematic representation of a second embodiment of a four-position switch in a fourth switching position from below.

The rotary handle 139 is in the fourth switching position. The rotary handle 139 can be rotated as far back and to the left until the pin 142 abuts the edge of the recess of the end cap 130.1 and the rotary handle 139 strikes the fixing ring 144.

Figures 19a to 19c and 20a to 20c show a further embodiment of the four-position switch 101.4 with rotary handle 139, each in a first axial stop position and rotates in a first switching position according to Figure 5a, 15b and in a second axial Anschlagpositton in a further switching position 17a, 17b. It may be disadvantageous to arrange the two reed switches 137.1 as in the previous figures 14 to 18 (ie 1 a, 14b, etc.) in alignment, since this can cause faulty circuits due to the engräumigen arrangement of the magnets and the reed switch 137.1. In the present additional advantageous embodiment, the four reed switches 137.1 are now distributed on the circumferential side and arranged in pairs offset axially. The Magnets for actuating the reed switch 137.1 are preferably arranged in the rotary handle 139 opposite in the jacket. Figures 19c and 20c show a cross-section transverse to a longitudinal direction of the switch. This clearly shows the circumferential arrangement of the reed switch 1 37.1 in the end cap 130.1. In the present case, two reed switches, which are responsible in pairs for the switching positions of an axial stop position, are arranged approximately at an angle of 60 °.

Figures 19d and 20d show the four-position switch 101.4 each in the corresponding switching position from above. In these figures, the rotary handle magnet 140 and the Endkappenmagnet 1 1 the maximum distance from each other - the magnets are so strong that when you release the knob 139, the neutral position is taken again.

In principle, it would be conceivable to detect the rotation of the rotary handle in the respective direction of rotation with two reed switches and to detect the axial position only by a single reed switch. In a further variant of the rotary handle switch can also be designed such that only three switching positions can be taken. The structure of such a switch substantially corresponds to those of Figures 14 to 20, but starting from the neutral position by pulling the rotary handle, only a third switching position is reached, in which no rotation of the rotary handle is provided. In principle, the switch can thus have three reed switches and make three different circuits. In a preferred embodiment, however, the switch has only two reed switches, which are arranged according to, for example, FIG. 3c or 3d. In such an embodiment, a larger magnet can be guided in the vicinity of both reed switch when pulling the rotary handle and so activate both reed switches together. This can save a reed switch.

Furthermore, the four-position switch according to FIGS. 1 to 20 can also be fastened to a mountain bike handlebar analogously to the rotary switch according to FIGS. 6 a and 6 b, the rotary handle being displaceable along the handlebar, preferably in FIG Direction of the handle. Likewise, the above variant could with three switch positions on one

Mountainbikenker be mounted.

The person skilled in the art also knows other variants of such switches.

FIG. 21 shows a schematic representation of a third embodiment of the four-position switch mounted on a mountain bike handlebar.

The four-position position switch 101 .3 is a type of embodiment preferably mounted on ountainbikelenkern 1 20 and described in detail with reference to FIG. 6a (external reed switch 36, FIG. 1). The four-position switch 101.3 is mounted between the brake handle 121 and the grip rubber 122. The rotary handle 139. 1 can be moved in four switching positions. The shift positions are achieved by turning to the left, turning to the right, pulling towards the grip rubber 1 22 plus turning to the left and pulling towards the grip rubber 122 plus turning to the right. The housing 33 ^ 1 is rotationally verrutsch- and m ^'connected to it a mountain bike handlebar 120 and includes the four reed switches. In contrast to the four-position switch according to Figure 6b, the reed switch are outside the handlebar tube. This is due to the further removal of the housing 133. 1 from the handlebar end. The Mountainbikelenker 120 is connected by the stem 1 12 with the steerer of a bicycle fork.

In variants, the four-shift position switch according to FIG. 6b with the inner reed switches can also be mounted in a mountain bike handlebar 120.

Figures 22a to 22d show a further embodiment of the invention. FIG. 22a shows a side view of a braking device 200 on a road handlebar, to which a two-position switch 2 10 immediately adjoins. This has a U-shaped actuating element 2 1 1, which is pivotally mounted at the lowest point 2 12. Figure 22b shows a sectional view in the direction of the pivot axis of the two-position switch 210. Center of the U-shape, starting from the pivot point 212, the actuating element within the U-shape, a switching rod 213, on which a magnet 214 is arranged. The fixed part also has a magnet 215, which is in the neutral position with the magnet 2 14 of the actuator 21 1 covers and thus keeps the actuator 2 1 1 in the neutral position. Reed switches 21 6 are arranged on both sides of the magnet 21 5 of the stationary element.

FIG. 22c shows the two-position switch 2 10 according to FIG. 22b in a first switching position in which the actuating element 2 1 1 is pivoted about the pivot axis 2 1 2. Thus, the magnet 214 of the actuating element 21 1 approaches the one reed switch 2 16 and actuates it. Analogously, FIG. 22d shows the second switching position. From both switching positions, the actuating element 2 1 1 is transferred after releasing due to the magnetic force in the neutral position. Finally, FIG. 22d shows the two-position switch 210 in the second switching position, with the actuating element 21 1 being pivoted about the pivot axis in the other direction with respect to FIG. 22c.

This two-position switch must not force to be mounted on a road handlebar, but can also be installed on other handlebar or otherwise, for example, in a steering wheel of a Motorfa rzeugs or the like, be used.

FIGS. 23a-c show a further variant of the switch according to the invention. The present switch essentially consists of a brake device 300 attached to a road handlebar with a brake lever 301, which is mounted pivotably on a pivot axis 302. The brake lever 301 has a U-shaped cross section in which a shift lever 303 is pivotally mounted on the same pivot axis 302. The operating side of the brake lever 301 is on the same side as the operating side of the shift lever 303. The operating direction of the shift lever 303 is the same as the operating direction of the brake lever 301. The shift lever 303 has a magnet 304 on the side opposite the operating side, and the brake lever 301 also has one Magnets 305, wherein the two magnets 304, 305 are positioned so that the shift lever 303 in the brake lever 301 assumes a neutral position. A fixed part 306 of the brake device finally has a reed switch 307. The shift operation may be performed when the brake lever 301 itself is in the neutral position. Now, the shift lever 303 is pressed in the direction of the brake lever 301 (this can in ergonomic manner with the thumb done), the magnet 304 of the shift lever 303 is guided to the reed switch 307, thus triggering a switching operation. After releasing the shift lever 303, the shift lever 303 pivots back to the neutral position due to the magnetic action. FIG. 23a shows the shift lever 303 and the brake lever 301 in the neutral position. In Fig. 23b, the shift lever 303 is in the shift position, and in Fig. 23c, the brake is operated, whereby the shift lever 303 can not be operated to initiate a shift.

In summary, it should be noted that is provided erf ^{'indungsgemäss} a switch which is extremely robust and more versatile.
