This patent document may show and/or describe matter which is or may become trade dress of the owner.

This disclosure relates to exercise systems and, more particularly, to a multi-functional combined resistance device and motor and interchangeable exercise devices for simulating exercise as a part of a combined exercise system.
There exist various types of exercise devices, many of which provide resistance to increase the power of the exercise. For example, weight systems enable users to add or reduce the amount of weight to increase or decrease resistance during exercise. Similarly, dedicated indoor cycles and road cycles fixed to training devices (so-called “trainers”) enable a user to control or implement systems whereby resistance is added to the pedals by any number of methods to increase endurance, power, and speed. Rowing machines operate with similar resistance to the user rowing.
Some systems rely upon manual addition of resistance through gearing, the application of a fixed brake, or even wind-based resistance (e.g., blower-style flywheels on wheels of old-style exercise cycles). More complex systems began enabling computer control of electronic resistance devices in the 1980s and 1990s. These systems typically enabled users to run through pre-programmed courses of simulated hills and flats and valleys with the associated increases and decreases in resistance controlled by a computer controller. Eventually, these systems led to still other systems where video tapes of exercise were synchronized with the computer-controlled resistance or with on-screen games.
These electronic controlled resistance devices were often magnetic combined with a small or sometimes large flywheel. The most realistic feeling trainers and bicycles utilize large flywheels to simulate the mass of the rider and bike. Even more modern resistance devices rely almost exclusively on carefully controlled magnets. They do spin, so in some sense they can act as flywheels, but virtually all of the added resistance and momentum is simulated by software through electromagnetic application of current on the spinning axle.
Throughout this description, elements appearing in figures are assigned three-digit reference designators, where the most significant digit is the figure number and the two least significant digits are specific to the element. An element that is not described in conjunction with a figure may be presumed to have the same characteristics and function as a previously-described element having a reference designator with the same least significant digits.
One unique characteristic of these exercise devices is that virtually all rely upon a computer-controlled electromagnetic motor. An electromagnetic motor that provides resistance to cycling may also provide resistance for any number of exercise devices. The motors for resistance are remarkably similar across devices. The electricity is simply run with more or less power to provide more or less resistance. All of this may be software-controlled by the associated exercise device or a connected software system for exercise (e.g. a game or integrated class software system).
A typical cyclist who lives in a location with cold climes may own multiple outdoor cycles (with some mounted to trainers), an indoor cycle, a hand bicycle, a weight training system, and one or more trainers. Each of those devices may have electrical components, an electrical motor, and other associated computers, controllers, displays or devices. It would be better for the environment and reduce overall electronic waste if at least some of those components could be reused or used in multiple components at different times for different purposes.
Accordingly, it would be beneficial if an electromagnetic motor could be used to provide resistance against exercise interchangeably in a number of potential exercise devices. Each of those functions could be computer controlled so as to operate as directed in a given exercise device.
The setups 110A-110D are exercise devices of various kinds. The options include, at least, indoor cycles, outdoor cycles, road cycles, mountain bikes, hand bikes, upper body ergometers, any kind of bicycle mounted to a trainer (e.g., trainer 112A), rowers, weight machines that rely upon resistance rather than free weights, elliptical machines, stair stepper machines, and virtually any resistance exercise device. The trainer 112A, indoor cycle 112B (which is representative of integrated indoor cycles including computer-controlled resistance systems), hand cycle 112C, and a rower 112D are shown merely as examples. Each includes an electromagnetic motor/resistance device.
Each of the setups 110A-110D includes a control device 113A-113D. In the case of the setups 110A-110D, the control devices 113A-113D may instruct an associated resistance device 111 to provide resistance for a given exercise.
The resistance device 111 is an interchangeable device that provides resistance in response to electric current. Preferably, the resistance device 111 is or includes an electric (electromagnetic) motor, but other types of electronically-controlled motors or resistance devices may be used (e.g. an electronically controlled fan brake). The resistance device 111 is interchangeable in the sense that it may be easily swapped into and out of an associated fitting, compartment, attachment point, or dock with an exercise device such as trainer 112A or hand cycle 112D to act as a resistance device therein.
The resistance device 111 receives current in varying amounts and converts that into resistance in opposition to or in conjunction with an exercising individual. When that power is applied against the rider, runner, or operator; then that is “resistance.” Examples include trainers, indoor cycles or rowing machines.
The resistance device 111 may be merely the motor itself, with a mechanical and electrical coupling to an associated exercise device. Preferably the coupling is such that insertion causes mechanical engagement of the motor as well as electrical coupling so as to enable the control devices 213A-213D to control the resistance device 211 without separately connecting the resistance device mechanically or electrically. In addition, the coupling or mount-point is preferably designed in such a way that the device may easily be joined, then may be engaged with a lever, clip, socket, or similar mechanism such that when inserted, some user action other than force against insertion is required to release the resistance device 211 from the exercise device.
Though the resistance device 211 is shown as a small device that may be inserted into a corresponding dock or void in an exercise device, the resistance device 211 may take many forms. It may be merely a motor with electrical and mechanical couplings. However, the resistance device may be an integrated form much like the trainers currently available (e.g. having an electric motor, a wheel, a base for holding up the resistance device when placed on a floor or mount, a flywheel, and/or associated mount points for electrical and mechanical coupling to an exercise device). The resistance device 211 itself may take many forms while otherwise meeting the other requirements such as interchangeability between exercise devices.
The control devices 113A-113D may be or include computing devices which are programmed to control the temporarily installed resistance device 111. The control device may be or include a display screen for, for example, displaying a game world, virtual world, and/or information regarding the workout (e.g. wattage, speed, total distance, information about upcoming changes in the workout or resistance applied, etc.). The control devices 113A-113D are shown as a single device, but may be multiple devices, such as a computing device, and a separate display or so-called smart TV that acts as both. In some cases, the control devices 113A-113D may be Apple® iPads or Android® or other tablet personal computing devices. Regardless, the control devices 113A-113D operate to adjust the resistance supplied by the resistance device.
The game server 120 may connect to the control devices 113A-113D through a network 150 (discussed below). The game server 120 may be a persistent online multiplayer game that enables users to engage in exercise with one another. In such a case, the game server 120 will serve a location, information about other users and associated graphics and avatars to a user of that software, while the user's control device 113A-113D provides to the game server 120 information about the user's speed, power, cadence, and the like. The Zwift® software is one such virtual game world. The game server 120 may instruct the control devices 113A-113D to alter the resistance applied by the resistance device 111, for example, in view of a virtual, in-game avatar climbing up a hill or descending a hill, so that the resistance matches the exertion necessary for a user's avatar in the virtual game world.
Alternatively, the game server 120 may not operate a game at all. The game server 120 may be a server that enables users to engage in exercise classes remotely from their homes or other locations using indoor or outdoor cycles. In such a case, the game server 120 may provide instruction to the control devices 113A-113D to alter the resistance applied by the resistance device 111 as directed by a class instructor. That instruction may be provided over the network 150 and may be directed or controlled (at least partially) by a class instructor.
Still further alternatively, the game server 120 may simply be a source of a routine or exercise instruction that is partially or wholly automated. In such a case, a user may be engaging in an exercise routine that is programmatically created or pre-created by a human, and that a user may progress through while the game server 120 actively controls the resistance (or power) applied at each part or the game server 120 provides an entire program that alters the resistance (or power) applied throughout an exercise routine.
The viewing screen 135 is a display for showing some or all of the game world and/or exercise routine details and/or performance statistics to a user or users. The viewing screen 135 may be present either for multiple users (e.g. in a group class) or for a single user (e.g. as a display under the direction of the control device 113B). So, for example, a group class may be presented with information about the exercise routine and their performance in the routine as it progresses. Or, for example, a user of the rower 112D may see an on-screen avatar moving through a virtual game world on the viewing screen 135 as directed by the control device 113D. The network 150 may or may not be involved in that communication, depending on the relative location of the control devices (nearby or over the internet) and the situation (group class, online race, single individual exercising outdoors or in his or her gym). Multiple viewing screens may be used, one by each user and/or one in each location.
The network 150 is a communications system that enables communication of data between the control devices 113A-113D, the game server 120, and, potentially, the viewing screen 135. The network 150 may be or include the internet. However, the network 150 may include 802.11x wireless networks, Bluetooth®, ANT+ connections, as well as other wireless protocols. The network 150 may also include wired connections such as ethernet.
The setup 210A includes a trainer 212A, and the control device 213A, as well as a resistance device dock 216A. The trainer 212A is a resistance device that mounts to a wheel or a hub (e.g. on the cassette) or an axle of a bicycle intended to operate as an outdoor cycle. Once connected, the trainer 212A operates as an electrically controlled brake on the wheel, axle or hub to thereby provide resistance to pedaling by a rider of the bicycle. The setup 210A preferably includes the cycle as well, but its function is well known so it is not discussed here.
The control device 213A includes a game engine 214A and data generation/integration 215A which are combined hardware and software components that perform instruction under the direction of the control device 213A and the game server 220. The game engine 214A is software, operating on a computing device (
The data generation/integration 215A is software and/or hardware the interacts with the trainer 212A to capture data about the exercising rider of the associated cycle. That data may include the power level the rider is cycling, the speed at which the associated trainer is turning, and any changes in those data inputs. The data generation/integration 215A obtains that information from the trainer 212A, generates associated signals and data that is provide over a network to the game server 220 to enable the game engine 214A to function. The data generation/integration 215A also interacts with the game engine 214A upon receipt of data from the game server 220 to show to a given rider the game world itself.
The resistance device dock 216A is a coupling, dock, receptacle or other detachable connection into which the resistance device 211 may mate. Preferably, the resistance device dock 216A is an actual dock into which the resistance device may “snap” or “couple” or otherwise engage with limited interaction of a user. The coupling or docking itself preferably also causes electrical connections between the control device 213A and the resistance device 211 to be connected. Similar examples include snap-in batteries designed for digital, portable cameras wherein the act of properly inserting the resistance device 211 simultaneously causes an electrical coupling to provide power to the resistance device 211.
In addition, the act of inserting the resistance device 211 preferably causes the device to mechanically join to the resistance device dock 216A for the trainer 212A such that the resistance device 211 is both electrically and mechanically coupled. Once those two elements are completed, then the resistance device 211 can be powered to provide resistance, and the application of power as directed by the control device 213A can mechanically engage the trainer 212A to provide physical resistance to the associated cycle, through the axle, the cassette, or through a hub.
Preferably, the mere insertion of the resistance device 211 into the resistance device dock 216A couples the resistance device 211 in such a way that it can provide resistance to the trainer 212A without any further connection (e.g. to a power source, or to a separate gear or axle). In this way, the user experience is substantially improved, by enabling easy, and quick insertion and removal of the resistance device 211 so that it may be reused in other exercise devices. Preferably, the insertion is of a “snap in” type so that a user may insert the resistance device 211 by snapping it into place, providing positive feedback for a user that it is in place and ready to function. Likewise, the resistance device 211 is preferably easily user ejectable through the operation of a lever, clip, pull, handle or other mechanism to enable the resistance device to easily and quickly be dislodged from the resistance device dock 216A, but not without specific intent and action to do so. By requiring some specific action (e.g. pulling a lever), accidental dislodgement can be avoided, while still enabling easy insertion and removal of the resistance device 211 so as to encourage users to utilize the resistance device 211 in multiple exercise devices.
All of the foregoing regarding setup 210A is discussed with reference to a game world. However, the “game world” may not exist in some implementations as discussed above. In such cases, the game engine 214A may simply be a system for delivering an exercise routine or class to a user, and the game server 220 may be a server that provides that routine or class. Data generation/integration 215A serves much the same function, enabling interaction with the game server and capturing and providing data from the trainer 212A to the game server 220 and from the game server 220 to the game engine 214A. That data may be captured and provided to the game server 220 in real time, as it is created, or may be stored until a given routine or class is completed. Likewise, a given routine or class may be provided by the game server 220 to the control device 213A in real time or prior to beginning the class or routine, depending on the particular implementation.
The setup 210C includes an hand cycle 212C (which may be an upper body ergometer) and the control device 213C, as well as a resistance device dock 216C. The functions here are identical to those in setup 210A, so only the differences will be discussed here. The hand cycle 212C may be a purpose-built cycle with pedals (handgrips) intended for operation by human hands. Commonly, outdoor versions of these hand cycles are tricycles, with a seat mounted between the two back wheels and the one front wheel. The hand grips often act as a handlebar as well. The indoor versions, as described for use in connection with a resistance device herein are typical single wheel or single flywheel (or trainer) systems with movable seats, and associated hand grips. No steering is necessary because they are fixed in a location. A computing device (e.g. control device 213C) may control the resistance applied by the resistance device to the hand grips.
As with the trainer 212A, the hand cycle 212C includes the resistance device dock 216C may replace or be an empty receptacle designed to hold the resistance device 211 and may be mounted otherwise much as an e-bike motor would be mounted. The only difference being that the motor itself is the resistance device 211 that may be removably connected within the receptacle. As with the trainer 212A, it is preferable, but not required, that the insertion of the resistance device 211 into the resistance device dock 216C causes the resistance device 211 to electrically and mechanically couple with the control device 213C and/or the hand cycle 212 so that it may be provided power by the control device 213C and controlled by the control device 213C while it provides resistance to the hand cycle 212C. The mechanical coupling occurs within the crank itself in a crank-mounted resistance device 211 or by causing movement of the wheel hub in a wheel-mounted resistance device 211.
The resistance device 211 is in most cases, in essence, an electric motor. When it is installed into the trainer 212A it is useful to provide motive power in opposition to a rider of the associated cycle. That resistance can be used to simulate wind, hills, or different types of roads (e.g. mud is harder than asphalt to ride upon). However, in an electronic bike, the same resistance device 211 may be used to provide motive power to assist a rider. The application of current to the resistance device 211 in one direction, as opposed to another, is typically all that is necessary to cause the resistance device 211 to alternate between assisting and providing resistance. The amount of current alters how much resistance or assistance. As a result, the same resistance device 211 may be used both in the trainer 212A to provide resistance, and later may be used in the hand cycle 212C to provide similar resistance. The resistance device 211 may be removably docked in or with one device or the other at a given moment.
The control device 213C is still a computing device, at least in part. There may or may not be a display associated with the device. However, the control device 213C still interacts with the resistance device 211 to provide power (or resistance) to the hand cycle 212C. That may be under the control of the rider (e.g. through a user interface enabling direct control), through a routine or programming, or through detection of pedaling whereby pedal assist engages automatically. The control device 213C may be connected to a network and reflect a user's exercise in a game world using the game engine 214C.
The game engine 214C also may operate differently on the control device 213C for the hand cycle 212C. For example, the hand cycle 212C being connected to the game engine 214C may result in the in-game avatar of the rider appearing as a rider on a hand cycle, as opposed to an upright bicycle. The associated statistics generated may vary as well, with a focus on the upper body (e.g. the hands and arms). Accordingly, the control device 213C may do many things with the game engine 214C while that is taking place.
The data generation/integration 215C may act to gather and store data about any exercises taking place while operating the hand cycle 212C for later integration into the game world, online or personally stored statistics, or online workout routines. The control device 213C and data generation/integration 215C may offload the generated data (e.g. using a mobile device and Bluetooth® connectivity).
The resistance device dock 216C preferably functions almost exactly or exactly like that in setup 210A. This similar or exact functioning enables the resistance device 211 to be interchangeably used in each.
The resistance device 211 is an electrically-controlled motor for providing resistance to either the trainer 212A or the hand cycle 212C or to any other exercise device that may rely upon resistance or the addition of power. The trainer 212A and hand cycle 212C are shown only by way of example. The resistance device is preferably an electric motor that may operate on direct current (e.g. batteries).
In some cases, the entire resistance device 211 may be a wheel, hub, axle and resistance device in one, physical package. That resistance device 211 may mount to any one of the exercise devices 212A-212D or any other exercise device in much the same way. Preferably, a mount point is designed for use with the resistance device 211 such that it may be easily mounted on to and off of a given exercise device without significant effort or time expended in doing so. Preferably this coupling simultaneously causes mechanical and electrical coupling of the resistance device 211 to the exercise device so that a single connection point results in the ability of the resistance device 211 to provide resistance and to receive electricity and control signals from, for example, the control device 213A. In some cases, a separate cord for electricity to the resistance device 211 itself may be required. Likewise, it is preferable for the resistance device 211 to be sufficiently light that a typical user can easily carry it and move it from device to device into which it may be integrated.
The game server 220 is a computing device (and may be many computing devices) that includes a client API 222, data storage 224, a world server 226, and a login function 228. The game server 220 is a computing device running software that enables the functions discussed herein. The game server 220 may be implemented in whole or in part as hardware or software.
The client API 222 is an application programming interface that enables sharing of data and communication from the game server 220 with other devices (e.g. the control device 213A and 213C) and vice versa. The client API 222 enables the control devices 213A and 213C to connect with the game server 220 to implement the game world and/or the exercise routines or other controls of the resistance device 211. The client API 222 may pass data back and forth and accept data sent to it from authorized sources.
The data storage 224 is preferably a database operating on the game server 220 that stores data. The data stored therein may be game data files for the game server 220 to operate, but may also include data about ongoing exercise (e.g. speeds, locations, power being applied, etc.) for exercisers who are engaged with the game server 220 using the trainer 212A and the hand cycle 212C and other, similar devices. The data storage 224 may retain historical records and statistics for users.
The world server 226 is game server software that operates on the game server 220 to enable the game engines 214A and 214C to present a game world to a rider, user, or exercising individual. As discussed above, this may be a game world like Zwift® with in-game avatars and exercise taking place simultaneously with many users. Alternatively, the world server 226 may instead be a service from which exercise classes are obtained or exercise routines are downloaded (or connected to in real-time). The world server 226 may take many forms, but it is a server service to which the control devices 213A and 213C (and others) can connect to enable interaction with one another. Data provided by the world server 226 may be used by the control devices 213A and 213C (and others) to adjust the resistance based upon data passed between devices using the client API 222 (e.g. a rider is on a hill, so the resistance should be increased or the class is in a sprint section, so resistance should be increased, etc.).
The login function 228 enables users of the control devices 213A and 213C to connect to the game server 220 to engage in exercise or otherwise download or upload data.

Description of Processes
Referring now to
Following the start at 605, the process begins with installation of the resistance device into a first exercise device at 610. This is preferably installation into a custom-designed dock to engage the electrical and mechanical coupling necessary for control and to provide power or resistance. However, in some cases, it may involve separate processes of mechanical coupling (e.g. joining a cassette or gear) and electrical coupling (e.g. with a wire).
Next, the user exercises with the resistance applied by the resistance device at 620. As discussed above, this is generally resistance to exercise (e.g. resistance to rowing or cycling). The user may engage in that exercise and the associated resistance may be variable, as controlled by a control device.
Next, a determination is made whether the given exercise is over at 625. This may be completion of an online ride using a trainer. If it is not complete (“no” at 625), then the process of exercise will continue at 620.
If the exercise is complete (“yes” at 625), then the process continues with the optional step (shown in dashed lines) of integrating exercise data into game service 630. This step may involve joining the data from the exercise with other data for prior exercises. This may be stored locally, but preferably is stored on a game server 220 (
Thereafter, the resistance device may be swapped to another exercise device at 640. Here, this may be transferring the resistance device from an indoor cycle to an rower or from a trainer to a resistance-based weight machine. Alternatively, it may be moving the resistance device from an hand cycle to a rower.
Next, the exercise device into which the resistance device was inserted is used by a user to engage in exercise at 650. Here, the resistance device may now provide resistance to the user of the second exercise device. So, the resistance device may resist rowing to simulate power necessary to move oars in water or may resist movement of the wheels of an indoor cycle to simulate hills or other difficult terrain.
Next, a determination is made whether the given exercise is over at 655. This may be completion of a commute home or may be terminating an online ride using a trainer. If it is not complete (“no” at 655), then the process of exercise will continue at 620.
If the exercise is complete (“yes” at 655), then the process continues with the optional step (shown in dashed lines) of integrating exercise data into game service 660. This step may involve joining the data from the exercise with other data for prior exercises. This may be stored locally, but preferably is stored on a game server 220 (
Thereafter, the process ends at 695.
Following the start 705, the process begins with installation of the resistance device in an exercise device at 710. This preferably involves insertion of the resistance device into a suitable receptacle or mounting point within the exercise device. Alternatively, the resistance device may be self-contained as a trainer-style device that may be joined using a mechanically and electrically connected socket, mount-point, or similar connection such that it may be easily joined to and removed from a given exercise device. The same socket, mount-point, or similar connection may be integrated into a family of exercise devices such that the resistance device may be mounted to any one of them for providing resistance to that device for various exercises. The resistance device may be an entire trainer, wheel, connective mount-point, and stand integrated into a single package.
Thereafter, a determination is made whether an instruction is received from the associated control device and/or a game server or other control system, to alter the exercise 725. In particular, this may be to increase resistance or decrease resistance or to make no change.
If the instruction is to increase the resistance, then current may be increased to the associated resistance device so that it may provide more resistance at 730. This may be carefully calibrated by the control device and associated resistance device to provide a precise level of resistance.
If the instruction is to decrease resistance, then decreased resistance may be provided at 740. Typically, this would be merely reducing the power applied against movement of a given exerciser.
If no change is desired at 725, or once resistance is increased at 730 or resistance is decreased at 740, the process continues with enabling the user to engage in the exercise at the desired resistance level at 750
A determination is made at 755 whether the exercise is complete. If not (“no” at 755), then the process continues with a determination whether there is an alteration to the exercise at 725.
If the exercise is complete (“yes” at 755), then the process ends at 795.
