Description

[0001] The invention relates to bicycle control devices, and more particularly to various features of a device for controlling a plurality of bicycle operating characteristics.

[0002] Bicycles have multiple operating components. For example, a bicycle transmission may include a plurality of front sprockets and a plurality of rear sprockets, with the plurality of front sprockets mounted for rotation with the pedals and the plurality of rear sprockets mounted for rotation with the rear wheel. To change the gear ratio of the bicycle transmission, a front derailleur shifts a chain to engage the various front sprockets, and a rear derailleur shifts the chain to engage the various rear sprockets.Because the length of chain required to engage a specific combination of front and rear sprockets varies depending on the selected sprocket combination, the chain must be long enough to engage the largest front sprocket and the largest rear sprocket, and some mechanism must be provided to take up the slack in the chain when the chain engages a smaller sprocket combination. Traditionally, the rear derailleur is equipped with a chain guide that includes an upper guide sprocket and a lower idler sprocket. The chain guide is spring-loaded to rotate to take up the slack in the chain.

[0003] When the bicycle is ridden over uneven terrain, the resulting shocks and vibrations can overcome the preload of the chain guide spring, and the chain guide can rotate in the direction of chain loosening. Such undesirable rotation increases the risk of the chain jumping off the currently engaged sprocket and / or becoming trapped between adjacent sprockets. To overcome such problems, various motion damping systems for the chain guide have been developed. For example, US 2012 / 0 083 371 A1, entitled "Bicycle Derailleur with Rotation Resistance," discloses a derailleur for bicycles comprising a base member, a movable member movably connected to the base member, and a chain guide connected to the movable member for rotation about a rotation axis.A resistance applying element applies a resistance against rotational movement of the chain guide, and a resistance control element is operatively connected to the resistance applying element such that the resistance applying element applies different first and second resistances against rotational movement of the chain guide when the resistance control element is arranged in the first and second positions, respectively.

[0004] Some bicycles include front and / or rear suspension members. The front suspension member typically includes a pair of shock absorbers forming opposite portions of the legs of the front fork, and the rear suspension member typically includes a shock absorber having one end mounted to the front portion of the frame and the other end mounted to a pivoting rear swing arm supporting the rear road wheel. In either case, the shock absorber usually includes an outer tubular suspension member and an axially telescopically retractable inner tubular suspension member. A piston has an outer peripheral surface sealingly and slidably engaged with the inner peripheral surface of the inner tubular suspension member to define a compression chamber in which a compressible fluid, such as air, is disposed.The piston is connected to the outer tubular suspension element by a piston rod. Some shock absorbers include separate chambers located on opposite sides of the piston, allowing additional operating parameters, such as ground clearance or stroke, to be controlled.

[0005] Some shock absorbers are designed to allow the driver to adjust certain operating parameters to adapt to changing driving conditions. Such parameters include spring preload (for shock absorbers using a coil spring), compression damping (to control the rate of shock absorber retraction), rebound damping (to control the rate of shock absorber extension), platform damping (to dampen shock absorber oscillation caused by pedal forces), cylinder pressure, cylinder volume, and lock (the ability to turn the normal shock absorbing function on and off).

[0006] Bicycles typically include adjustable saddles. A typical bicycle saddle has a seat mounted on a seat post. The seat post is sized to insert into a seat tube of the bicycle frame, and a clamp is used to clamp the seat tube around the seat post, thereby holding the saddle at a desired height. Some bicycles include an electric motor with a gear that meshes with teeth on the seat post to electrically adjust the saddle height and hold the saddle at a desired height.

[0007] EP 2 128 014 A1 discloses a bicycle shifting device comprising a base member for coupling to a bicycle frame, a movable member movably coupled relative to the base member, a chain guide coupled to the movable member for guiding a chain between a plurality of sprockets in response to movement of the movable member, and a preload device that exerts a preload force on the chain guide to tension the chain. Furthermore, the bicycle shifting device includes a movement resistance device with a control element for applying a signal that causes the movement resistance device to change the resistance to movement of the chain guide.

[0008] It is the object of the present invention to provide a bicycle operating characteristic control device that enables comfortable and reliable use of the bicycle.

[0009] The object is achieved by a bicycle operating characteristic control device according to independent claim 1. Advantageous further developments are described in the dependent claims.

[0010] The invention relates to various features of an apparatus for controlling a plurality of bicycle operating characteristics. In one embodiment, a bicycle operating characteristic control apparatus comprises a first bicycle component and a second bicycle component, wherein the second bicycle component can be changed from a first state to a second state. The first bicycle component includes a base member for connection to a bicycle frame, a movable member connected for movement relative to the base member, and a chain guide connected to the movable member for guiding a chain between a plurality of sprockets in response to movement of the movable member. A pretensioning device provides a pretensioning force to the chain guide to tension the chain, and a rotational resistance changing device changes a rotational resistance of the chain guide relative to the movable member.The first bicycle component and the second bicycle component are functionally connected so that the rotational resistance of the chain guide changes in conjunction with a change in the status of the second bicycle component.

[0011] In the following, various embodiments of the present invention are described by way of example, wherein Fig. Figure 1 is a side view of a bicycle incorporating specific embodiments of adjustable components; Fig. 2 a detailed view of specific embodiments of components mounted on the handlebar of the Fig. 1 shown bicycle; Fig. 3 is a block diagram of a specific embodiment of a control mechanism; Fig. Figure 4 is a schematic diagram of a manually operated control device operatively connected to two other bicycle components; Fig.5 is a schematic diagram of another embodiment of a manually operated control device operatively connected to two other bicycle components; and Fig. Figure 6 is a schematic diagram of a manually operated control device operatively connected to two or more other bicycle components.

[0015] A bicycle seat in the form of a saddle 86 is mounted to a front frame portion 14 by means of a seat post 88 that is telescopically inserted within a seat tube 92 of a front frame portion 14. A saddle position sensor 96 is mounted on the seat tube 92 and cooperates with the seat post 88 to detect the position of the saddle 86 relative to the seat tube 92. A saddle position drive device 98 ( Fig.3) is mounted in the seat tube 92 and connected to the seat post 88 to adjust the height of the saddle 86. The saddle position drive device 98 may be an electric motor, for example, a motion spindle motor, or may be a pneumatic motor, a hydraulic fluid motor, etc. The saddle position sensor 96 may include: a variable electrical resistance, such as a contact strip mounted on the seat tube 92 and an electric brush mounted on the seat tube 88, a potentiometer having a splined shaft mounted on the seat tube 92 and a rack formed or mounted in the seat post 88, an optical sensor having a phototransistor mounted in the seat tube and a closure strip mounted on the seat post 88, an internally mounted pressure sensor (in the case of a pneumatic or hydraulic drive motor), or any other suitable sensor.

[0016] As in Fig.As shown in Figure 2, respective grips 100a, 100b and brake levers 104a, 104b are provided at both ends of the handlebar assembly 41. The brake lever 104a is provided with the front wheel brake 48 for braking the front wheel 42, and the brake lever 104b is provided with the rear wheel brake 50 for braking the rear wheel 46. Control units 108a, 108b are provided inside the grips 100a, 100b and the brake levers 104a, 104b, respectively, and a bicycle characteristics control unit 112 is attached to the central portion of the handlebar assembly 41.

[0017] Control units 108a and 108b are used to switch the front derailleur gearshift 76 and the rear derailleur gearshift 80, to control the height of the saddle 86, and to control the operating characteristics of the rear suspension 26 and the front suspension 40. Specifically, a front upshift button 116a, a front downshift button 116b, a saddle upshift button 116c, and a front suspension control button 116d are provided in the control unit 108a, and a rear upshift button 118a, a rear downshift button 118b, a saddle downshift button 118c, and a rear suspension control button 118d are provided in the control unit 108b. In this embodiment, upshift buttons 116a and 118a provide signals to the bicycle property control unit 112 to upshift the front and rear derailleur gearshifts 76 and 78, respectively.80 by one gear step, and downshift buttons 116b and 118b provide signals to a bicycle feature control unit 112 to downshift front and rear derailleur gearshifts 76 and 80, respectively, by one gear step. Saddle raise button 116c provides signals to the bicycle feature control unit 112 to raise the saddle 86, and saddle lower button 118c provides signals to the bicycle feature control unit 112 to lower the saddle 86. Front and rear suspension control buttons 116d and 118d provide signals to the bicycle feature control unit 112 to control a number of functions of front and rear suspensions 40 and 26, respectively. Such functions will be described in more detail later.

[0018] As in Fig.3, the bicycle characteristic control unit 112 is electrically connected via suitable wiring to the electrical components associated with the control units 108a, 108b, to the electrical components associated with the rear suspension 26, to the electrical components associated with the front suspension 40, to the electrical components associated with the front derailleur gearing 76, to the electrical components associated with the rear derailleur gearing 80, and to the electrical components associated with the saddle 86. Of course, the bicycle characteristic control unit 112 may also be operatively connected to any of these components via suitable wireless communication devices.

[0019] The bicycle property control unit 112 includes: a control unit 122 having a CPU 126, a memory 130, a saddle position signal receiver 131 receiving the saddle position signals from the saddle position sensor 96, a gear position signal receiver 132 receiving gear position signals from the front derailleur position sensor 76 and the rear derailleur position sensor 82, a suspension control unit 133 providing control signals to control the operating parameters of the rear suspension member 26 and the front suspension members 40, a resistance control unit 135 providing control signals to control the resistance applied to the chain guide 80c, a display unit 134 displaying the current gear ratio and other information, an on / off switch 136, a mode switch 138, and a rear derailleur resistance control switch 140.The CPU 126 is a programmed processor that operates according to the information stored in the memory 130. The saddle position signal receiving device 131 and the gear position signal receiving device 132 may include suitable input ports and buffers to convert the input signals into suitable signals for use by the control programs, and they may include wireless receivers, optical receivers, etc. The on / off switch 136 turns the bicycle property control unit 112 on and off. The mode switch 138 changes an operating mode of the bicycle property control unit 112 and may be used in conjunction with the front suspension control knob 116d and the rear suspension control knob 118d to select and control the desired functions of the rear suspension member 26 and the front suspension member 40.The resistance control switch 140 is used to control user-controllable operating parameters of the rotary resistance changing device 83.

[0020] As in Fig. 2, the bicycle property control unit 112 includes a box-like housing 142. Display unit 134, on / off switch 136, mode switch 138, and resistance control switch 140 are arranged on the upper surface of housing 142. As shown in Fig. 1 and Fig. 3, the bicycle property control unit 112 is connected to the electrical components associated with the front derailleur gear system 76, the electrical components associated with the rear derailleur gear system 80, the electrical components associated with the rear suspension member 26, and the electrical components associated with the front suspension members 40 by means of a connection unit 146.

[0021] In this embodiment, front suspension elements 40 comprise a pair of pneumatically operated shock absorbers. As shown schematically in Fig.3, each shock absorber includes a first member (e.g., a piston) 148 that moves relative to a second member (e.g., a cylinder chamber) 150. External adjustment elements are for low-speed and high-speed compression damping (e.g., driver control units 154, 162 and a separate lever-operated adjustment knob 158, 166 for each setting), for stroke (piston travel or compression chamber volume) (e.g., driver control unit 170 and lever-operated adjustment knob 174), for air chamber pressure (e.g., driver control unit 178 and air valve 182), for rebound damping (e.g., a driver control unit 186 and a lever-operated adjustment knob 190), for lock actuation (e.g., a driver control unit 194 and a lever-operated actuation knob 198), for lock force adjustment (e.g., a driver control unit 200 and a lever-operated adjustment knob 202), and for height adjustment (e.g.Driver control unit 204 and lever-operated adjustment knob or valve 206).

[0022] In this embodiment, a rear suspension member 26 comprises a combined air and oil actuated shock absorber having a first member (e.g., a piston) 207 moving relative to a second member (e.g., a cylinder chamber) 208 with a typical outboard spring (not shown in the drawings). External adjustment elements are for spring preload (e.g., a driver control unit 210 and a lever-operated adjusting nut 214), for low-speed and high-speed compression damping (e.g., driver control units 218, 222 and a separate lever-operated knob 226, 230 for each setting), for air chamber pressure adjustment (e.g., a driver control unit 234 and an air pressure adjustment valve 238), for air chamber volume adjustment (e.g., a driver control unit 242 and a lever-operated adjusting screw 246), for rebound damping (e.g.,a rider control unit 250 and a lever-operated adjustment knob 254), for lock actuation (e.g., a rider control unit 258 and a lever-operated actuation knob 262), for lock force adjustment (e.g., a rider control unit 266 and a lever-operated adjustment knob 270), for platform (anti-bobble) adjustment (e.g., a rider control unit 274 and a lever-operated actuation valve 278), and for height adjustment (e.g., rider control unit 280 and a lever-operated adjustment knob or valve 282). Air chamber pressure and volume settings can be used to adjust the pressure and volume of the main air chamber or for platform (pedaling) damping. Examples of such parameter settings can be found on current shock absorbers sold by, for example, Fox and Manitou.

[0023] Rider control units for adjustments that make adjustments in a continuous manner (e.g., compression damping of rear suspension member 26 and front suspension members 40, rotational resistance of rear derailleur gearing 80) may include continuous motion motors or any other suitable motor, along with position sensors (potentiometers, resistance position sensors, optical position sensors, contact switches, etc.) that indicate the actuated position of the associated knob, lever, or other adjustment. If desired, each rider control unit may include its own microprocessor to control the operation of its associated motor in response to signals provided by suspension control unit 133 and resistance control unit 135, and to provide status signals to control unit 122.Similarly, rider control units for adjustments that make adjustments in discrete increments (e.g., three-stage travel adjustment of the rear suspension elements 26 and front suspension elements 40, multi-stage resistance adjustment (low, medium, high, etc.) for rear derailleur gearing 80) may comprise stepper motors or other suitable motors along with position sensors indicating the operating position of the associated knob, lever, or other adjustment, and any desired additional microprocessors. Rider control units for adjustments that operate in an on / off manner (e.g.,Locking actuation of the rear suspension member 26 and the front suspension member 40, ON / OFF resistor for rear derailleur gearshift 80) may comprise a solenoid or any other suitable drive means, together with position sensors indicating the operating position of the associated knob, lever, or other adjustment member, and with any desired additional microprocessors.

[0024] In this embodiment, the electrical components associated with the rear suspension 26, the electrical components associated with the front suspension 40, the electrical components associated with the rear derailleur gearing 80, and the electrical components associated with the saddle 86 are operatively connected such that changes made to one component result in changes in the status or operating characteristic (e.g., position, movement, pressure, or volume ratio of a first element relative to a second element) of at least one other component. The following tables provide examples of the linked operation of various components when performing a simple ON / OFF operation on the rotational resistance changing device 83 for the rear derailleur gearing 80. Table 1 Rear derailleur resistance Front suspension locking OUT OF TO TO OUT OF Table 2 Rear derailleur resistance Height of the front suspension OUT OF LOW TO HIGH Table 3 Rear derailleur resistance Rear suspension locking OUT OF TO TO OUT OF Table 4 Rear derailleur resistance Platform damping of the rear suspension OUT OF TO TO OUT OF Table 5 Rear derailleur resistance Saddle height OUT OF HIGH TO LOW

[0025] The following tables provide examples of the linked operation of various components when multi-stage operation is performed in the rotational resistance changing device 83 for the rear derailleur gear shifting device 80. Table 6 Rear derailleur resistance Height of the front suspension OUT OF LOW ON - low resistance MEDIUM ON - great resistance HIGH Table 7 Rear derailleur resistance Saddle height OUT OF HIGH ON - low resistance MEDIUM ON - high resistance LOW

[0026] Of course, the operation of any number of components can be linked, as shown in the following table. Table 8 Resistance of the rear derailleur Height of the front suspension Platform damping of the rear suspension Saddle height OUT OF LOW TO HIGH TO HIGH OUT OF MEDIUM

[0027] In the preferred embodiment, the resistance of the rear derailleur acts as the reference variable. In other words, after the user sets the desired resistance of the rear derailleur, the algorithm checks the status of the rotational resistance change device 83 for the rear derailleur gearshift 80 and then adjusts the other components at approximately the same time. For example, in the Fig.In the embodiment illustrated in Figure 8, the algorithm first determines whether the rear derailleur resistance is set to OFF. If so, the front suspension height 40 is set to LOW, the rear suspension platform damping 26 is set to ON, and the saddle height 86 is set to HIGH. Of course, the status or operating characteristic of any component could be used as a reference variable depending on the application, and the status or operating characteristic of more than one component could be used as a combination of reference variables using a suitable Boolean operation.

[0028] For example, in the described embodiment, the resistance applied to rotation of the chain guide 80c of the rear derailleur 80, the height of the saddle 86, and the operating characteristics of the rear suspension 26 and the front suspension elements 40 were electrically controlled, but the teachings could also be applied to the manual operation of one or more components. For example, as schematically shown in Fig.4, a single manually operated control device 300, such as a control lever, may be connected to a manually operated control member in the rotational resistance changing device 83 and to a manually operated control member in the saddle position drive device 98 by means of two Bowden cables 304 and 308 connected in parallel, one end of each Bowden cable 304 and 308 being operatively connected to the manually operated control device 300, and the other end of a Bowden cable 304 being connected to the manually operated control member in the rotational resistance changing device 83, and the other end of Bowden cable 308 being operatively connected to the manually operated control member in the saddle position drive device 98.

[0029] Alternatively, as shown schematically in Fig.5, a manually operated control device 300 may be operatively connected to the manually operated control component in the rotational resistance changing device 83 by means of a first Bowden cable 312, and the manually operated control component in the saddle position drive device 98 may be operatively connected to the manually operated control device 300 by means of a second Bowden cable 316 that is spliced ​​to an intermediate location 320 of the first Bowden cable 312.

[0030] As shown schematically in Fig.6, the manually operated control device 300 could be operatively connected to the manually operated control component in the torque change device 83 by means of a first Bowden cable 324 and operatively connected in parallel to the manually operated control component in the saddle position drive device 98 by means of a Bowden cable 332 or a spliced-in Bowden cable 336, to one or more manually operated control components 328 in the front suspension members 40 by means of a Bowden cable 340 or a spliced-in Bowden cable 344, and / or to one or more manually operated control components 350 in the rear suspension member 26 by means of a Bowden cable 354 or a spliced-in Bowden cable 358. Of course, the components could also be operatively connected in series.

[0031] While air- and oil-operated shock absorbers have been disclosed, any pressure-operated or spring-operated shock absorbers could be used, such as hydraulically operated shock absorbers. Any operating characteristic (e.g., pressure; volume; position; movement, such as on / off, velocity or acceleration; resistance to movement, etc.) of a first element relative to a second element of any number of components can be controlled based on a similar operating characteristic of one or more reference components.

[0032] As used herein, the term "locking" of a shock absorber does not necessarily mean that the first shock absorbing element (e.g., outer tubular suspension element) is completely immobile relative to the second shock absorbing element (e.g., telescopically movable inner tubular suspension element). Locking refers to the fact that normal shock absorbing function is disabled. In the locked state, the first shock absorbing element may exhibit some movement relative to the second shock absorbing element due to manufacturing and / or hydraulic tolerances. Also, some shock absorbers may have a threshold shock value beyond which the second shock absorbing element is permitted to move significantly relative to the second shock absorbing element, or even engage normal shock absorbing function, to prevent damage to the shock absorber during harsh driving conditions.

[0033] In the disclosed embodiments, bicycle components such as front suspension member 40, rear derailleur 80, etc., functioned as slave devices operated by master control devices, such as operating units 108a and 108b. In other words, the bicycle components controlled by operating units 108a and 108b did not function as master control devices directly operating other bicycle components. However, in some embodiments, a bicycle component functioning as a slave component may also function as a master control device for any other bicycle component.

[0034] The size, shape, location, and orientation of the various components can be changed as needed and / or desired. Components depicted as directly connected or in contact with each other may have intermediate structures arranged between them.
