Description

Background of the invention

[0001] The invention relates to bicycle control systems. In particular, the invention is directed to systems comprising wirelessly activated controls for bicycle gear shifters and / or bicycle suspensions and other bicycle components and systems.

[0002] Electronic devices and wireless communication are widespread in modern society. Operating such devices during activities requiring concentration and control, such as riding a bicycle, can be dangerous. This is because the user input for the controls is traditionally located on the handlebars of a bicycle. In some cases, with well-designed controls, the rider's hands are close to the controls, so activating them poses little risk. However, if the rider's hands are located further away from the controls, the rider must move one hand towards the controls and temporarily steer the bicycle with the remaining hand.Furthermore, should the driver wish to activate the control switch during braking, the driver would have to remove his hands from the brake lever and temporarily interrupt braking in order to activate the control switch.

[0003] WO 2003 / 012 615 A2 discloses a glove with integrated sensors that can be activated by the wearer. Activating the sensors triggers signals that control another device, such as a watch. The signals can be transmitted wirelessly.

[0004] DE 60 2005 001 339 T2 discloses a switching arrangement and a gear position sensor integrated into a brake assembly. The gear position sensor can wirelessly transmit information about the gear position to a display unit.

[0005] DE 102 52 557 A1 discloses a suspension fork for a bicycle which can be controlled wirelessly.

[0006] There is a need to provide a way to control remotely operated electronic devices on a bicycle while allowing the rider to maintain contact with the handlebars and a visual connection to the road ahead. The present invention provides a means for wirelessly controlling multiple devices without requiring the rider to change their hand position on the handlebars.

[0007] Prior art controls are typically mounted on the bicycle's handlebars. US Patent 2008 / 0168856A1 shows shift buttons integrated into the brake lever assembly and shift buttons mounted directly on the handlebars. This requires a structure to mount the switches to the handlebars, increasing weight. Mounting the switches on the handlebars requires the rider to reach for specific positions to activate a shift. If alternative positions are desired, additional, separate switches must be mounted on the handlebars. The switches can all be connected by cables or wires, increasing complexity and weight. Alternatively, they can all be designed wirelessly, requiring separate power sources for each device, again increasing weight and complexity. Summary of the invention

[0008] According to embodiments of the present invention, control devices, which may be shift control devices, can be worn by or attached to a rider and thus follow the rider to alternative hand positions. A single power source is required when all shifting is performed with one hand, and only two when both hands are used. The shift control devices are easy to transport from bicycle to bicycle, and only one set is needed. Furthermore, the shift control devices do not need to be removed from the handlebars for recharging, as they are not attached to the handlebars.

[0009] Aspects of the present invention relate to a bicycle shifting system in which the front and rear derailleurs are wirelessly controlled by a wireless shifting control device or devices located not on the handlebars but on the rider. In one embodiment, the rider carries the shifting control device on their hands and performs shifting by a specific movement of the finger or fingers of that hand. Such movements or actions should not occur during normal cycling to avoid unintentional shifting.

[0010] Some examples of these movements include: 1. Flicking the index finger; 2. simultaneous touching of the thumb and any of the other fingers, possibly with a threshold force; 3. Hyperextension of any of the five fingers beyond the normal range of motion; 4. Compression of the fingertips instead of the ball of the finger; and 5. any combination of the foregoing actions.

[0011] Alternatively, the invention relates to a system with control devices for controlling suspension components or systems or other wirelessly controllable components or systems of the bicycle.

[0012] The invention also benefits from single-button shifting. With single-button shifting, each hand requires an actuator, button, switch, or similar device connected to the shifting control unit. For example, a right-hand actuator would cause the rear derailleur to shift in one direction, a left-hand actuator would cause the rear derailleur to shift in the other direction, and simultaneous activation of both actuators would cause the front derailleur to switch from its current inner or outer position.

[0013] The invention comprises a means for shifting the front and rear derailleurs of a bicycle from the rider's hands instead of from the bicycle's handlebars. In this way, the user input for controlling the shifting follows the hands, regardless of their position.

[0014] Other embodiments of the invention relate to arranging the switching control device in a different wearable position than on the rider's gloves. For example, the control device could be attached to other textiles or accessories worn by the rider. In a further embodiment, the sensor could be a microphone, and the commands to trigger the generation of a control signal could be auditory rather than physical movement.

[0015] In some embodiments, a battery may be provided for each individual switching control device to eliminate wires or connectors.

[0016] One aspect of the invention is a control device wearable by a cyclist, wherein the control device comprises at least one wearable switching control sensor that generates input signals when activated. A control processor connected to the at least one switching control sensor generates control signals in response to the input signals. A wireless transmitter is responsive to the processor for sending the control signals. A power source is connected to the control processor and the wireless transmitter.

[0017] Another aspect of the invention is a shifting system for a bicycle, comprising a shift control device. The shift control device includes at least one portable shift control sensor for generating input signals when actuated, a shift control processor that communicates with the at least one shift control sensor and generates control signals in response to the input signals, a wireless transmitter that sends the control signals, and a power source connected to the shift control sensor and the wireless transmitter. The system includes an electromechanical rear derailleur, comprising a wireless rear derailleur receiver that receives the control signals, a rear derailleur motor responsive to the received control signals, and a rear derailleur power source connected to the wireless rear derailleur receiver and the rear derailleur motor.

Detailed description of the invention

[0018] Embodiments of the invention are described with reference to the drawings. It is understood that the drawings and accompanying descriptions are provided for illustrative purposes only and do not limit the invention as defined by the claims included herein, nor any and all of its equivalents. For example, the terms "first" and "second," "in front" and "behind," or "left" and "right" are used for clarity and not as limiting terms. Furthermore, these terms refer to bicycle mechanisms attached to a bicycle in a conventional manner, and the bicycle being oriented and used in a conventional manner, unless otherwise indicated.

[0019] Fig. 1 and Fig. Figure 16 shows a bicycle 20 having a frame 22 to which a front wheel 24 and a rear wheel 26 are attached in conventional positions. A handlebar 28 is attached near the front of the bicycle 22, and a pair of brake actuators 30 are attached to the handlebar. A front derailleur 32 may be attached to the frame 22 on or near a front crank / chainring assembly 34. A rear derailleur 36 is attached to the frame 22 near the rear wheel 26. A chain 38 connects the front crank / chainring assembly 34 and a set of sprockets 40, which are attached to and coupled with the rear wheel 26.

[0020] A state-of-the-art switch 42 is in Fig. Figure 2 shows the switch 42 as an example of a handlebar-mounted electronic switch. The switch 42 includes a brake lever 44 with shift buttons 46 and 48 attached to the brake lever. The brake lever 44 is attached to a housing section 50 of the switch 42, which in turn is attached to the handlebar 28. When a rider wants to initiate a shift, the rider's hand must be positioned either on the housing section 50 or on the handlebar 28 immediately below the housing in order to reach the shift buttons 46 and 48. If the rider's hand is positioned elsewhere, the controls are out of reach and the bicycle cannot be shifted.

[0021] Fig. Figure 2 also shows a shift control switch 52 independent of the housing 50. This switch 52 can be clamped to the handlebar 28 and provides a separate location from which the rider can shift the derailleurs. However, to obtain a separate shift location, cables 53 must be routed from the primary shift location, or alternatively, the second shift location must have a separate power source, processor, and wireless output means 51 independent of the first. This significantly complicates the setup, as cables are typically placed under handlebar tape, and increases the likelihood of cable or connector failure as the number of shift buttons increases.

[0022] The Fig. 3 and Fig. Figure 4 shows examples of a wireless electromechanical front derailleur 32 and a wireless electromechanical rear derailleur 36. In these examples, the power source 54 for each derailleur device 32, 36 can be attached directly to the device and can be in the form of a battery. Furthermore, each device 32, 36 is equipped with a wireless communication device 55B (which may include a receiver, a transmitter, or a combination of a transmitter and receiver) connected to a CPU 56 to enable the devices to communicate wirelessly with a remote transmitter of a control device, such as a shift control device (see Figure 4). Fig. 5) or a control device for actuating a component or system of the bicycle that is not related to gear shifting, such as a bicycle suspension component or system. Each of the wireless electromechanical front derailleurs 32 and wireless electromechanical rear derailleurs 36 is equipped with an electric motor (not shown) for triggering it, as is well known from the prior art. Referring to Fig. 16 Each of the front and rear suspension systems 86, 88 comprises a motor and a wireless communication device, like those in the preceding examples, but configured to actuate suspension components or the suspension systems.

[0023] Signals sent by the control device can include those indicating either an upshift or downshift (i.e., a type of control signal) for either the front or rear derailleur 32, 36. The control signal can also be a change in the state of the suspension system. The control signal can be sent to all derailleur devices 32, 36 or be coded to control a derailleur. Furthermore, the transmission can be encrypted to prevent anyone other than the sender of the signal from replicating or receiving it, thereby preventing others from controlling that particular device.

[0024] Fig. Figure 5 shows a glove 58 that supports or forms a substrate for the control device 57, the latter comprising control sensors 60, 62 in the finger areas 64 of the glove. The control sensors 60, 62 are connected by integrated links 66. The integrated links 66 connect the sensors 60, 62 to a processor 69 (which may also be known as a control CPU or control processor), which is any suitable microprocessor capable of generating control signals in response to input signals from the control sensors. A wireless transmitter 55A is connected to the processor 69 for transmitting the control signals. A power source 54 supplies power to the processor 69 and transmitter 55A (see Figure 5). Fig. 7).

[0025] The processor 69, transmitter 55A, and power source 54 of the control device 57 can be arranged in a combined form or provided as separate components on the glove 58. The processor 69, transmitter 55A, and power source 54 of the control device 57 can collectively be referred to as an electronic control unit 68 (ECU). The control device 57 can include an optional interface 70 by means of which the electronic control unit 68 can be detached from the glove, according to one embodiment even without the use of tools.

[0026] Detection actions performed by the user with the control device 57 can be accomplished in various ways, as described below. The integrated connections 66 can be wires, conductive fabrics, or any conductive material or composite, extending to specific points on each finger and connected to the ECU 68. As indicated above, the electronic control unit 68 can comprise any combination of circuits, a power source, a transmitter and optional receiver device, and a processor (CPU) or the like, programmable with computer code to operate and control the unit for its intended use. Optionally, the glove 58 and / or the ECU 68 can include a display of any kind or a device for generating feedback (not shown), which may be, for example, visual or audible.

[0027] Interface 70 can allow for the detachable attachment of the sensitive electronics (ECU 68), so that the glove can, for example, be washed. Similarly, the shift control sensors 60, 62 on the fingers of the glove 58 can be designed to be permanently attached to the glove, or they can be removable to allow cleaning of the glove or to allow the sensors to be transferred from one glove to another. Furthermore, the electronics can be designed separately from the driver's glove 58 itself and used as an insert [liner], for example, inside a driver's glove, as a cover over the driver's glove, or as a device attached directly to the driver's hands, connecting the shift control sensors 60, 62 to the fingers and the ECU 68 to the hand, away from the shift control sensors for use without a glove.

[0028] Fig. Figure 6 shows the control sensors 60, 62, and 72, which are arranged on the fingers 64 of a glove 58 according to an embodiment of the invention. In the illustrated example, the sensors 60, 62, and 72 can comprise conductive pads, each arranged on or near each finger area 64 of the glove. Conductive cables 66 run from the pads to the ECU 68. When a rider brings two pads into contact, a circuit is closed or the state of the circuit changes. Fig. 6. The rider's index finger and thumb touch. This specific contact combination can indicate that an upshift of the rear derailleur 36 is desired and will accordingly result in the generation and transmission of a control signal indicating this. Likewise, pressing the thumb and middle finger together can indicate that a downshift of the rear derailleur 36 is desired and will result in the generation and transmission of a control signal indicating this.

[0029] An embodiment of an electrical circuit diagram of a wireless communication system 76, which is responsive to control signals generated by the glove-bound control device 57, is described in Fig. 7 shown. The ones in the Fig. 7, Fig. 11 and Fig. The 13 systems (76, 176, 276) shown can each comprise an electromechanical front derailleur 32 and an electromechanical rear derailleur 36, each derailleur comprising a power source 54, a CPU 56, and a wireless communication device having at least one wireless derailleur receiver 55B. Optionally, the derailleurs can be provided in addition to or replace one or more suspension components or systems. The ECU 68 comprises a power source 54, a switching control processor (CPU) 69, and a wireless transmitter 55A.

[0030] To prevent unintended circuits, a specific contact time or pressure can be preset when sensors 60 and / or 62 are actuated. The switching control processor (CPU) 69 can be programmed to ignore the closed circuit if it occurs for a shorter time than required or if an input signal occurs too soon after a preceding input signal. Alternatively, the resistance of the closed circuit can be measured, and if the circuit is closed but the resistance is found to be too high, this can be suspected as an unintended input signal. Thus, the switching control processor 69 can be programmed to reject unintended input signals.

[0031] As in Fig. As shown in Figure 6, the system is not limited to switching a single device with a corresponding single control device 57. The control device 57 can be configured to have only one circuit and thus generate only one shift control signal. A right glove with a control device 57 can generate an upshift signal for a rear derailleur 36, and a left glove with a control device 57 can generate a downshift signal for a rear derailleur 36. Meanwhile, a separate circuit arranged on each glove can control the shifting of the front derailleur 32, or alternatively, the front derailleur can be caused to shift from one gear position to the next by closing both circuits in both gloves simultaneously.

[0032] Fig. Figure 8 shows an example of a shift control sensor in the form of a flexible pressure-sensitive resistor 78, sold under the trade name Flexiforce® and manufactured and distributed by Tekscan. Flexiforce® is a piezoelectric resistor sensing device in which resistance is inversely proportional to an applied force. This type of device can be used in the driving gloves 58 either in the ball of the finger ( Fig. 9) or in the fingertip areas ( Fig. 10) be integrated. A schematic representation of this system is shown in Fig. Figure 11 shows this type of pressure-sensitive switch 78. It is very thin and can be easily integrated into a glove without altering its shape or appearance. Likewise, it has no moving parts, unlike a conventional switch.

[0033] Fig. Figure 11 shows a circuit system 157 comprising a sensor 78 of the type described above. To actuate the sensor 78, the shift control processor 69 generates a voltage across the sensor 78. When no pressure is applied to the sensor 78, the detected resistance is relatively high because the current passing through the sensor 78 is negligible. When a rider wishes to shift gears, the rider presses on the sensor 78. As the force or pressure on the device increases, the resistance decreases. With a decrease in resistance, the current increases. Once the current reaches a predetermined threshold, the shift control processor 69 determines that a shift is desired. The shift control processor 69 is programmed to ignore forces below the predetermined threshold, thus preventing unwanted shifting.Optionally, the front derailleur(s) can be provided in addition to, or replace, one or more suspension components or systems. In this case, the shift control system 157 (the shift control systems) would switch the state of one or more suspension components or systems.

[0034] It is understood that the pressure-sensitive switch 78 can be considered an improvement compared to individual mechanical switches. Nevertheless, a mechanical switch, if correctly designed, can offer many of the same advantages. Accordingly, among the broader aspects of the invention, embodiments are also envisaged that include individual mechanical switches arranged separately on the fingers of the driver's glove. In the Fig. 9 to 11 the pressure-sensitive switch 78 can be replaced with a mechanical switch, which allows modification with respect to the mechanical bundling and possibly other requirements of the switch.

[0035] Fig. Figure 12 shows another embodiment of a control device 257 with switching control sensors in the form of accelerometers mounted on a glove 58, which are connected to an ECU 268. Accelerometers are used to measure changes in acceleration and orientation, as is conventionally used in mobile phones or video game controllers. An example of such a device is the “ADXL330 Low-Power, 3 axis + / -3G mems” accelerometer manufactured by Analog Devices. Such devices have many advantages over switching control sensors. They require little power, are extremely durable, and do not require contact with other objects to trigger. The sensors simply detect their relative position in space as a function of gravity and a change in position as a function of acceleration.For example, the orientation of the device relative to the surface can be used to indicate a switching signal.

[0036] As in Fig. As shown in Figure 12, the accelerometer is attached to the back of the index finger. When the index finger is raised horizontally to the ground, the sensor assumes an orientation in which only one axis of the accelerometer 68 is subject to an acceleration force of gravity. This is shown graphically in the Fig. 14A-C shown, wherein the acceleration values ​​measured by the X and Y axes reverse when the orientation of the accelerometer 80 changes from a position that is essentially vertical to a position that is essentially horizontal.

[0037] An alternative use of the accelerometer 80 is to measure the acceleration applied to it and to set a threshold acceleration beyond which a shift command can be determined. This is similar to the pressure-sensitive resistors discussed above. Normal riding exerts forces on the rider's hands from the bicycle when riding over road irregularities, as do normal contact forces with the handlebars while riding. The CPU 69 can be programmed to recognize only those accelerations above a predetermined value as an intended shift signal, thus enabling the rider to generate this value himself by tapping a finger on the handlebar with sufficient force.The rapid deceleration of the finger upon contact with the handlebars would be higher than the forces originating from the road, since these road-induced forces are dampened by the air in the tires and the flexibility of the wheels, frame, stem, and handlebars.

[0038] Fig. Figure 13 shows a further embodiment of a wireless communication system 276, comprising a front derailleur 32 and a rear derailleur 36, each including a corresponding power source 54, CPU 56, and wireless communication device 55B. The shift control device 257 includes an ECU 268 and associated accelerometers 80. The ECU 268 communicates wirelessly with the derailleurs 32 and 36, as in the preceding examples.

[0039] Fig. Figure 15 shows another embodiment of a wireless control device 357 that can be worn on a rider's helmet 82. In this embodiment, the sensor is a microphone 84 or the like. The helmet can also carry an ECU 368, which can comprise the same components as in the preceding examples. In particular, the ECU 368 can comprise a power source, a wireless transmitter, and a control processor, as described above. The control processor of the ECU 368 is configured to receive input signals (generated by voice commands) from the microphone 84 and to analyze the input signals using conventionally known speech recognition software. The control processor 368 can be configured to generate control signals for controlling a bicycle gear-shifting component or system and / or a suspension component or system and / or any other controllable components or systems of the bicycle.

[0040] Fig. Figure 16 shows a bicycle which, in addition to the aforementioned components, has a front suspension system 86 and an optional rear suspension system 88. Each of the front and rear suspension systems 86, 88 includes a motor (not shown) for actuating one or more parameters of the system and electronic components for actuating the motor. It is understood that the characteristics of the motor and the electronic components will be adapted in accordance with the intended use, be it a gear-shifting device, a suspension device, etc.

[0041] For example, in an embodiment where the wireless control device 357 is used to control a rear suspension component or system 88, the control device can be programmed to respond to commands corresponding to 1) lockout, 2) pedal action, and 3) open suspension settings. In an embodiment where the wireless control device 357 is used to control a front suspension component or system 86, the control device can be programmed to respond to commands corresponding to 1) lockout, 2) pedal action, and 3) open suspension settings. The control device 357 could control both of the front and rear suspension components 86, 88 separately or together, with, for example, a single lockout voice command being able to change both of the front and rear suspensions to a lockout setting simultaneously.Alternatively, the control device 357 could be programmed to control the front and rear suspensions 86, 88 separately.

[0042] In an embodiment in which the wireless control device 375 is used to control a wirelessly controlled rear derailleur or rear shifting component or system, the control device can be programmed to respond to commands corresponding to, for example, "up" or "down," "heavier" or "lighter," or "1, 2, 3, 4," etc., to change the bicycle's gear position in single increments. The control device 375 could also generate a shift command to cause a shift of more than one gear position in response to a single command. For example, the rider could say "two up" or "two down" to shift two gear positions up or down. The rider could say "all the way up" or "all the way down" to shift the derailleur to one of the outermost gear positions in a single operation.The control device 357 according to the present embodiment could offer a wide range of flexibility and programmability if it is responsive to voice commands. Similarly, the control device 357 could be used to control a wirelessly controlled front derailleur.

[0043] In a similar manner, the control device 357 could also be programmed to control other systems (not shown) of the bicycle, such as lights, electric generators and other systems such as heart rate monitors, GPS units, power meters and speedometers and the computer units that collect, analyze and display data relating to the bicycle system.

[0044] In these embodiments, the rider's hands exercise individual control of one or more derailleurs in a manner that does not require the control devices to be connected to the bicycle.

[0045] Although this invention has been described with reference to particular embodiments, it should be understood that numerous modifications could be made to the inventive concept and its scope. Accordingly, the invention is not intended to be limited to the disclosed embodiment, but rather to have the full scope permitted by the wording of the following claims.
