Definitions
- This disclosure relates generally to exercise equipment and more particularly to systems and methods for providing resistance in exercise equipment.
- Resistance training is a core element to strength and conditioning programs. Resistance training involves a person performing a movement, while one or more muscles are under a load. The load is generally referred to as resistance. There are a multitude of different exercises that can be performed under resistance. Regardless of the exercise, however, performing resistance training requires some way of providing a load as a person is performing a movement.
- a trainee uses a weight to provide a load.
- Two of the most common weight lifting methods are the use of free weights or weight machines.
- Free weights are generally barbells and dumbbells that a person raises or lowers while performing a movement.
- Weight machines on the other hand, generally include one or more weight stacks that a user raises or lowers through a supplementary mechanism (e.g. cables, pulleys, levers, gears, cams, etc.).
- Some weight machines use free weights to provide a load.
- a system in one embodiment, includes a motor, at least one drive screw attached to the motor.
- the drive screw has an axis of rotation and is configured such that the motor can turn the drive screw in a first direction and a second direction around the axis of rotation.
- a carriage is coupled to the drive screw. The carriage moves axially in a first direction relative to the drive screw when the drive screw is turned in a first direction and a second direction relative to the drive screw when the drive screw is turned in a second direction.
- At least one sensor is attached to the carriage, wherein the at least one sensor is configured to detect external force on the carriage.
- a processor and a memory coupled with the processor are included in the system.
- the memory comprises executable instructions that when executed by the processor cause the processor to effectuate operations.
- the operations include receiving information from the sensor indicative of the external force on the carriage. Utilizing the information to determine a movement of the carriage in response to the external force and instructing the motor to turn the drive screw to apply the movement.
- an exercise apparatus in one embodiment, is provided.
- a housing includes a sidewall defining a space and including a first end and a second end.
- a motor is disposed within the housing at the first end.
- At least one drive screw is disposed within the housing.
- the drive screw is rotatably attached at a first end to the motor and at a second end to the housing.
- a carriage is attached to the drive screw. Rotation of the drive screw in a first direction causes the carriage to move toward the first end of the housing and rotation of the drive screw in a second direction cause the carriage to move toward the second end of the housing.
- a mechanical actuator is attached to the carriage.
- the mechanical actuator is configured to allow a user to perform an exercise movement.
- a controller is configured to detect movement of the carriage through the mechanical actuator and to respond to the movement by instructing the motor to rotate the drive screw to move the carriage in response to the movement.
- a method for applying force in an exercise apparatus includes a motor, a drive screw connected to the motor, a carriage connected to the drive screw, and a sensor that detects force applied to the carriage.
- An operational mode is received through a user interface.
- a direction and a magnitude of a first force that has been applied to the carriage is detected.
- the magnitude and direction are used to determine a responsive force to apply to the carriage, wherein the responsive force is corresponds to the operational mode of the exercise apparatus.
- the motor is instructed to turn the drive screw to apply the responsive force to the carriage.
- FIG. 1A and FIG. 1B are functional block representations of exemplary systems for providing varying resistance in exercise equipment.
- FIGS. 2A-2C are perspective views of an exemplary resistance machine that may utilize the system of FIG. 1A and FIG. 1B .
- FIG. 3A and FIG. 3B are a perspective view and side view respectively of an exemplary resistance machine that may be used with the system of FIG. 1A .
- FIG. 3C and FIG. 3D are close up views of a carriage that may be used in the resistance machine of FIG. 5A and FIG. 5B .
- FIG. 4 is perspective view of an exemplary curl machine that may that may utilize the system of FIG. 1A .
- FIG. 5 is an exemplary block diagram depicting a computing device that may be used as a controller in the system of FIG. 1A and FIG. 1B .
- FIG. 6 is a flowchart depicting illustrative operation of the system of FIG. 1A and FIG. 1 B.
- FIG. 1A is a representative system 10 for providing varying resistance in exercise equipment.
- system 10 comprises carriage 12 , having an inner structure 14 and an outer structure 16 , a drive screw 18 , a motor 20 , a controller 22 , and one or more sensors 24 .
- inner structure 14 and outer structure 16 may each comprise a plate, frame, and/or another type of body that are moveable with respect to each other.
- inner structure 14 and outer structure 16 may be moveably attached to each other such that they move laterally with respect to each along the axis A of drive screw 18 .
- More detailed exemplary embodiments of inner structure 14 and outer structure 16 will be further provided herein. However, for the purposes of FIG. 1 , it is sufficient to recognize that they move laterally with respect to each other along the direction of axis A. It should also understood that inner structure 14 and outer structure 16 may also move in other directions with respect to each other without departing from the scope of the disclosure.
- inner structure 14 includes threaded openings 15 through, which it is rotatably engaged with drive screw 18 .
- Rotatable engagement with drive screw 18 causes inner structure 14 to move along axis A when drive screw 18 is rotated.
- inner structure 14 is substantially fixed in place along axis A. The direction that inner structure 14 moves is determined by the direction of rotation of drive screw 18 .
- outer structure 16 in one example is not connected to drive screw 18 .
- outer structure 16 is positioned in a different plane than drive screw 18 . Therefore, outer structure 16 floats substantially above or below the plane of drive screw 18 depending on the orientation from which one views carriage. Because, drive screw 18 is not connected to outer structure 16 and outer structure 16 is on a different plane than drive screw 18 , movement of drive screw 18 does not directly impart movement to outer structure 16 .
- at least one connecting device 28 connects inner structure 14 to outer device.
- Such a connecting device 28 could take many including, but not limited to, flexible and expandable materials, such as springs, rubber, foam, and combinations thereof.
- Such materials may be used in connection with other materials, such as bolts, brackets, shims, rails, tracks, etc. to connect inner structure 14 and outer structure 16 together in a moveable manner.
- the connection of inner structure 14 and outer structure 16 allows drive screw 18 to impart movement to outer structure 16 by rotating and thereby by moving inner structure 14 to impart a force on outer structure 16 through connecting devices 28 .
- a single connecting device 28 is shown in FIG. 1 for illustrative purpose, but multiple connecting devices 28 may be used. For instance, a connecting device may reside at each corner of inner structure 14 .
- outer structure 16 may be actuated by another device or actor.
- a mechanical actuator such as a bar, a pulley system, a handle, a cable, and or a lever, etc. may be attached to outer structure 16 and allow a user to actuate movement of outer structure 16 relative to inner structure 14 , which is held in place by drive screw 18 . This allows a user to provide force, such as in a weightlifting movement, indirectly against inner structure 14 .
- drive screw 18 extends along and beyond a length L of carriage 12 .
- drive screw has first end 26 and a second end 27 .
- First end 26 is mechanically coupled to motor 20 .
- Second end 28 may be rotatably seated within a housing of a machine (not shown).
- Motor 20 turns drive screw 18 around axis A.
- the rotation of drive screw 18 around axis A combined with the engagement of drive screw with the threaded openings 15 causes inner structure 14 to move relative along axis A.
- motor 20 may be used to provide force on carriage along the direction of axis A by turning drive screw 18 .
- Such force may be varied by the direction of rotation of the drive screw 18 and varied in magnitude by the torque at which motor 20 operates.
- controller 22 and sensors 24 in one example are utilized to measure the force exerted between inner structure 14 and outer structure 16 .
- a first sensor 30 may be a slide potentiometer that measures the displacement of inner structure 14 and outer structure 16 .
- a second sensor 32 may be an angle potentiometer.
- An angle potentiometer may be used to measure an angle of an external structure relative to outer structure 16 .

- two sensors 24 are depicted for illustrative purposes, but more sensors 24 may be used and in different configurations. Sensors 24 measure the direction and magnitude of force exerted by inner structure 14 on outer structure 16 and provide such measurements to controller 22 , which operates motor 20 in accordance with one or more algorithms and/or routines with which controller 22 is programmed.
- controller 22 may be programmed to instruct motor 20 to drive screw 18 in a first direction when a certain force is imparted by outer structure 16 on inner structure. For instance, a user may perform a movement in which the user provides force against outer structure 16 , which causes outer structure 16 to move relative to inner structure 14 . Sensors 24 will report such force to controller 20 and controller 20 may be programmed to either allow such force at a certain magnitude (in the case of a positive portion of an exercise movement) or to resist such movement and drive carriage 12 in the opposite direction and at a certain magnitude (in the case of negative movement). In another example, system 10 may be in an operating mode in which controller 22 allow carriage 12 to move freely.
- such a mode may be to allow user to move carriage 12 to a desired position.

Abstract
Description
- This patent application claims priority to and the benefit of pending provisional patent application 62/780,794 filed Dec. 17, 2018, which is incorporated herein by reference in its entirety.
- This disclosure relates generally to exercise equipment and more particularly to systems and methods for providing resistance in exercise equipment.
- Resistance training is a core element to strength and conditioning programs. Resistance training involves a person performing a movement, while one or more muscles are under a load. The load is generally referred to as resistance. There are a multitude of different exercises that can be performed under resistance. Regardless of the exercise, however, performing resistance training requires some way of providing a load as a person is performing a movement.
- In basic resistance training, such as weight training, a trainee uses a weight to provide a load. Two of the most common weight lifting methods are the use of free weights or weight machines. Free weights are generally barbells and dumbbells that a person raises or lowers while performing a movement. Weight machines, on the other hand, generally include one or more weight stacks that a user raises or lowers through a supplementary mechanism (e.g. cables, pulleys, levers, gears, cams, etc.). Some weight machines use free weights to provide a load.
- One problem associated with existing resistance equipment is that the resistive loads do not vary over time. When a user performs a movement with free weights, the weight remains the same during the beginning, middle, and end of the movement. However, due to biomechanics, a user may be able to handle more weight at various stages of the movement. For instance, it is understood that a user can usually handle more weight during the negative part of a movement than in the positive part of a movement. Similarly, there are exercises, such as the squat, in which a trainee can lift more weight at the top of the movement than at the bottom of the movement. However, there is no way to add weight to a barbell or dumbbell during a movement, other than to stop the movement and manually add plates. This is not efficient and not even practical for certain types of movements.
- In one embodiment, a system is provided. System includes a motor, at least one drive screw attached to the motor. The drive screw has an axis of rotation and is configured such that the motor can turn the drive screw in a first direction and a second direction around the axis of rotation. A carriage is coupled to the drive screw. The carriage moves axially in a first direction relative to the drive screw when the drive screw is turned in a first direction and a second direction relative to the drive screw when the drive screw is turned in a second direction. At least one sensor is attached to the carriage, wherein the at least one sensor is configured to detect external force on the carriage. A processor and a memory coupled with the processor are included in the system. The memory comprises executable instructions that when executed by the processor cause the processor to effectuate operations. The operations include receiving information from the sensor indicative of the external force on the carriage. Utilizing the information to determine a movement of the carriage in response to the external force and instructing the motor to turn the drive screw to apply the movement.
- In one embodiment, an exercise apparatus is provided. A housing includes a sidewall defining a space and including a first end and a second end. A motor is disposed within the housing at the first end. At least one drive screw is disposed within the housing. The drive screw is rotatably attached at a first end to the motor and at a second end to the housing. A carriage is attached to the drive screw. Rotation of the drive screw in a first direction causes the carriage to move toward the first end of the housing and rotation of the drive screw in a second direction cause the carriage to move toward the second end of the housing. A mechanical actuator is attached to the carriage. The mechanical actuator is configured to allow a user to perform an exercise movement. A controller is configured to detect movement of the carriage through the mechanical actuator and to respond to the movement by instructing the motor to rotate the drive screw to move the carriage in response to the movement.
- In one embodiment, a method for applying force in an exercise apparatus is provided. The exercise apparatus includes a motor, a drive screw connected to the motor, a carriage connected to the drive screw, and a sensor that detects force applied to the carriage. An operational mode is received through a user interface. A direction and a magnitude of a first force that has been applied to the carriage is detected. The magnitude and direction are used to determine a responsive force to apply to the carriage, wherein the responsive force is corresponds to the operational mode of the exercise apparatus. The motor is instructed to turn the drive screw to apply the responsive force to the carriage.
- In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of the variations in implementing the disclosed technology. However, the instant disclosure may take many different forms and should not be construed as limited to the examples set forth herein. Where practical, like numbers refer to like elements throughout.

FIG. 3C andFIG. 3D are close up views of a carriage that may be used in the resistance machine ofFIG. 5A andFIG. 5B . -
FIG. 4 is perspective view of an exemplary curl machine that may that may utilize the system ofFIG. 1A . -
FIG. 5 is an exemplary block diagram depicting a computing device that may be used as a controller in the system ofFIG. 1A andFIG. 1B . -
FIG. 6 is a flowchart depicting illustrative operation of the system ofFIG. 1A andFIG. 1 B. -
FIG. 1A is arepresentative system 10 for providing varying resistance in exercise equipment. In one embodiment,system 10 comprisescarriage 12, having aninner structure 14 and anouter structure 16, adrive screw 18, amotor 20, acontroller 22, and one ormore sensors 24. - In one example,
inner structure 14 andouter structure 16 may each comprise a plate, frame, and/or another type of body that are moveable with respect to each other. For instance,inner structure 14 andouter structure 16 may be moveably attached to each other such that they move laterally with respect to each along the axis A ofdrive screw 18. More detailed exemplary embodiments ofinner structure 14 andouter structure 16 will be further provided herein. However, for the purposes ofFIG. 1 , it is sufficient to recognize that they move laterally with respect to each other along the direction of axis A. It should also understood thatinner structure 14 andouter structure 16 may also move in other directions with respect to each other without departing from the scope of the disclosure. - Referring further to
FIG. 1A ,inner structure 14 includes threadedopenings 15 through, which it is rotatably engaged withdrive screw 18. Rotatable engagement withdrive screw 18 causesinner structure 14 to move along axis A whendrive screw 18 is rotated. In addition, it should be understood that whendrive screw 18 is not rotated,inner structure 14 is substantially fixed in place along axis A. The direction thatinner structure 14 moves is determined by the direction of rotation ofdrive screw 18. - Referring further to
FIG. 1A ,outer structure 16 in one example is not connected to drivescrew 18. In one example,outer structure 16 is positioned in a different plane thandrive screw 18. Therefore,outer structure 16 floats substantially above or below the plane ofdrive screw 18 depending on the orientation from which one views carriage. Because,drive screw 18 is not connected toouter structure 16 andouter structure 16 is on a different plane thandrive screw 18, movement ofdrive screw 18 does not directly impart movement toouter structure 16. Nevertheless, in one example, at least one connectingdevice 28 connectsinner structure 14 to outer device. Such a connectingdevice 28 could take many including, but not limited to, flexible and expandable materials, such as springs, rubber, foam, and combinations thereof. Such materials may be used in connection with other materials, such as bolts, brackets, shims, rails, tracks, etc. to connectinner structure 14 andouter structure 16 together in a moveable manner. The connection ofinner structure 14 andouter structure 16 allowsdrive screw 18 to impart movement toouter structure 16 by rotating and thereby by movinginner structure 14 to impart a force onouter structure 16 through connectingdevices 28. It should be noted that a single connectingdevice 28 is shown inFIG. 1 for illustrative purpose, but multiple connectingdevices 28 may be used. For instance, a connecting device may reside at each corner ofinner structure 14. - Referring further to
FIG. 1A , becauseouter structure 16 is not connected to drivescrew 18 and is outside the plane ofdrive screw 18, outer structure does not requiredrive screw 18 to move. Accordingly,outer structure 16 may be actuated by another device or actor. For instance, a mechanical actuator, such as a bar, a pulley system, a handle, a cable, and or a lever, etc. may be attached toouter structure 16 and allow a user to actuate movement ofouter structure 16 relative toinner structure 14, which is held in place bydrive screw 18. This allows a user to provide force, such as in a weightlifting movement, indirectly againstinner structure 14. - Referring further to
FIG. 1A , drivescrew 18 extends along and beyond a length L ofcarriage 12. In one embodiment, drive screw hasfirst end 26 and asecond end 27.First end 26 is mechanically coupled tomotor 20.Second end 28 may be rotatably seated within a housing of a machine (not shown).Motor 20 turns drivescrew 18 around axis A. The rotation ofdrive screw 18 around axis A combined with the engagement of drive screw with the threadedopenings 15 causesinner structure 14 to move relative along axis A. Accordingly,motor 20 may be used to provide force on carriage along the direction of axis A by turningdrive screw 18. Such force may be varied by the direction of rotation of thedrive screw 18 and varied in magnitude by the torque at whichmotor 20 operates. - Referring further to
FIG. 1A ,controller 22 andsensors 24 in one example are utilized to measure the force exerted betweeninner structure 14 andouter structure 16. In one example, afirst sensor 30 may be a slide potentiometer that measures the displacement ofinner structure 14 andouter structure 16. Asecond sensor 32 may be an angle potentiometer. An angle potentiometer may be used to measure an angle of an external structure relative toouter structure 16. For instance, a lever may be attached toouter structure 16 and an angle potentiometer may be used to measure the angle of the lever relative toouter structure 16, as will be discussed in more detail herein. It should be noted that twosensors 24 are depicted for illustrative purposes, butmore sensors 24 may be used and in different configurations.Sensors 24 measure the direction and magnitude of force exerted byinner structure 14 onouter structure 16 and provide such measurements tocontroller 22, which operatesmotor 20 in accordance with one or more algorithms and/or routines with whichcontroller 22 is programmed. - Referring further to
FIG. 1A , in one example,controller 22 may be programmed to instructmotor 20 to drivescrew 18 in a first direction when a certain force is imparted byouter structure 16 on inner structure. For instance, a user may perform a movement in which the user provides force againstouter structure 16, which causesouter structure 16 to move relative toinner structure 14.Sensors 24 will report such force tocontroller 20 andcontroller 20 may be programmed to either allow such force at a certain magnitude (in the case of a positive portion of an exercise movement) or to resist such movement and drivecarriage 12 in the opposite direction and at a certain magnitude (in the case of negative movement). In another example,system 10 may be in an operating mode in whichcontroller 22 allowcarriage 12 to move freely. For example, such a mode may be to allow user to movecarriage 12 to a desired position. In such a mode, the slightest force exerted oninner structure 14 by outer structure may causecontroller 22 to rotatemotor 20 so that carriage move rapidly to the desired position. In another example, a user may want to perform an isometric exercise. An operating mode may be programmed such thatcontroller 22 does not movecarriage 12 regardless of the force exerted byouter structure 16 againstinner structure 14. - Because
motor 20 andcontroller 22 can selectively rotatedrive screw 18 to movecarriage 12 alongaxis A. System 10 may be utilized in exercise equipment to provide variable resistance while users perform certain movements. The programming ofcontroller 22 may be customized according to the objectives of the individual users, manufacturers, and/or personal trainers. An exemplary device that may be utilized ascontroller 22 is discussed in connection withFIG. 5 . It should be noted thatcontroller 22 may include an input/output device that would allow a user toprogram system 10 and/or select an operating mode forsystem 10. Therefore, while exercising a user could select an exercise program, increase resistance, and decrease resistance as needed. A user's selections would be effectuated bycontroller 22 tailoring the direction of movement and torque ofmotor 20 to provide the resistance desired by the user. Furthermore, such resistance can be varied over time by varying the torque and/or direction of themotor 20. - Referring to
FIG. 1B , another embodiment ofsystem 10′ is shown for exemplary purposes.FIG. 1B depicts an embodiment in which there are twodrive screws 18 rather than the onedrive screw 18 shown inFIG. 1A . The use of twodrive screws 18 may be advantageous in certain exercise applications. For example, thesystem 10 ofFIG. 1A may be utilized in a resistance machine, such as squat, press, or leg extension machine in which onedrive screw 18 may be sufficient to accomplish its purpose. - In addition, the configurations shown in
FIGS. 1A and 1B are also illustrative. It is envisioned thatsystems multiple carriages 12,motors 20, andcontrollers 22 without departing from the scope of the disclosure. An example of usingsystem 10 withmultiple motors 20 and/or controllers would be a multifunction exercise apparatus. Such an apparatus may be configured to have a squat, a press, and leg extension at the same time. Onecarriage 12,drive screw 18,motor 20, andcontroller 22 could govern all functions ormultiple carriages 12, drive screws 18,motors 20, andcontrollers 22 could be used, such that each function would have dedicated hardware. Another example, would be to configuresystem 10 with multiple drive screws 18 which would each be driven by adedicated motor 20. As an example, such a configuration may be worthwhile to provide higher levels of resistance since twomotors 20 could perform more work than onemotor 20. Such a use case may be effective for users who require a greater degree of resistance, such as bodybuilders or power lifters. - Referring to
FIG. 2A , an embodiment of aresistance machine 200 incorporatingsystem 10 is shown for illustrative purposes.Resistance machine 200 in one example includes ahousing 201 comprising abase 203, atower 205, asupport member 207, and alever 209.Base 203 provides a support on which a user can stand when using the machine.Base 203 also functions to provide support tomachine 200 such that it remains upright.Tower 205 acts as the housing within whichsystem 10 resides.Support member 207 supportsmachine 200 in an upright position and includespivot point 208 at whichlever 209 is attached. - Referring further to
FIG. 2A ,housing 201 has atop end 211 and abottom end 213. A top surface is positioned attop end 211. Asidewall 215 runs betweentop end 211 andbottom end 213.Sidewall 215 in one example may be closed and comprise a continuous material defining anopening 216 within whichsystem 10 resides. In another example,sidewall 215 may be open and comprise one or more members or rails oriented to extend longitudinally betweentop end 211 andbottom end 213. - Within opening 216, one or
more rods 217 extend longitudinally fromtop end 211 tobottom end 213 ofhousing 201. Ifplural rods 217 are used, then they would extend longitudinally in a parallel arrangement. Positioned on therods 217 are one ormore carriages 12.Carriages 12 are positioned similar to the carriage shown inFIG. 1A .Carriages 12 includeinner structure 14 andouter structure 16 that slide with respect to each other alongrods 217.Inner structure 14 and outer structure are separated by springs 221 (or alternative elastic and compressible elements).Inner structure 14 includes a threadedopening 15 through which drivescrew 18 extends. Drivescrew 18 in one example is rotatably seated ontop end 211 of housing and extends longitudinally towardbottom end 213 of housing at which it is connected tomotor 20.Outer structure 16 includes one ormore pegs 223 to whichlever 209 may be attached. Referring also toFIGS. 2B and 2C ,lever 209 is adjustable between a top position (FIG. 2B ) and bottom position (FIG. 2C ) in addition to middle position (FIG. 2A ).Lever 209 is adjusted bycontroller 22 instructingmotor 20 to movelever 209 by movingcarriage 12 through rotation ofdrive screw 18. In this way, thelever 209 may be moved to different positions corresponding to different starting points of an exercise. For example,FIG. 2A may be a starting point for a squat or press.FIG. 2B may be a starting point for an overhead pull down.FIG. 2C may be a starting point for a bent over row. - Referring further to
FIG. 2A ,lever 209 in one example includes aninterface 225 to which one or more attachments may be connected to allow a user to perform various exercises. In the example shown, a paddedsquat attachment 227 is shown, which would allow users to orient themselves to perform a squat. Other attachments include put not limited to handles, a bar, a rope, or a band, which would allow a user to perform push and pull exercises such as presses and pulldowns. - One or
more sensors 24 may be present to measure the displacement betweeninner carriage 14 andouter carriage 16 in the manner described inFIGS. 1A and 1B .Sensors 24 may include alinear potentiometer 30 to measure displacement betweeninner carriage 14 andouter carriage 16. Anangle potentiometer 32 may be positioned atpivot point 208 to measure the angular position oflever 209 relative to supportmember 207. The angular position oflever 209 will affect the force applied to/from carriage from/to a user. Accordingly, angular position oflever 209 is used by controller in its calculation of how much force to apply through rotation of drive screws 18. - Referring further to
FIG. 2A , in one example, a user operatesmachine 200 by actuatinglever 209 to push or pull it towardtop end 211 orbottom end 213. As this movement occurs,outer structure 16 is displaced relative toinner structure 14.Sensors 24 detect the extent of the displacement and send signals tocontroller 22.Controller 22 responds to displacement in accordance with the operational mode that it is in and directsmotor 20 accordingly.Motor 20 may do nothing (in an isometric mode) or it will turn drive screw in one direction to allow the movement (in a positive direction of a movement) at a certain force corresponding to a user's desired weight or turn drive in a second direction (in a negative direction of movement).Controller 22 may also specify the force or torque at which motor 20 should turn drivescrew 18. Asdrive screw 18 turns,inner structure 14 will apply force againstouter structure 16 and thecarriage 12 will move as described inFIGS. 1A-1B . - Referring to
FIG. 3A-3B , another embodiment of anexercise machine 300 utilizingsystem 10 is shown for illustrative purpose.Machine 300 includes similar structure to themachine 200 shown inFIGS. 2A-2C . There ishousing 301 comprising abase 303, atower 305, and asupport member 307. Thehousing 301 has atop end 311 and abottom end 313. Asidewall 315 runs betweentop end 311 andbottom end 313.Sidewall 315 in one example may be closed and comprise a continuous sheet of material defining anopening 316 within whichsystem 10 resides. In another example,sidewall 315 may be open and comprise one or more members or rails oriented to extend longitudinally between top surfacetop end 311 andbottom end 313. - Within opening 316, one or
more rods 317 extend longitudinally from top surface 314 andbase 303. Ifplural rods 317 are used, then they would extend longitudinally in a parallel arrangement. Positioned on therods 317 are one ormore carriages 12.Carriages 12 includeinner structure 14 andouter structure 16 that are slide with respect to each other along rods 319.Inner structure 14 andouter structure 16 are separated by springs 321 (or alternative elastic and compressible elements).Inner structure 14 includes a threaded opening through which drivescrew 18 extends. Drivescrew 18 in one example is rotatably seated on one side ofsurface 214 and extends longitudinally towardbase 303 where it is connected tomotor 20. - Unlike
exercise machine 200,machine 300 does not include alever 209 to allow user to operate it.Machine 300 is configured as leg extension and leg curl apparatus.Machine 300 includes abench 320 that is configurable between an upright leg extension position and a reclining leg curl position. An “L” shapedarm 322 is rotatable attached tobench 320 atpivot point 324. - Referring to
FIG. 3B , acable 326 having afirst end 328 and asecond end 330 is attached toarm 322 at the first end and attached toouter structure 16 ofcarriage 12 atsecond end 330. A pulley system directs cable fromarm 322 longitudinally towardtop end 311 ofhousing 301. - Referring to
FIG. 3C , in one example,cable 326 is attached to outer structure through the use of amagnetic holding mechanism 332.Holding mechanism 332 comprises amagnet 334 having an opening through which it is positioned on one of therods 317. Ametallic member 336 is attached to thesecond end 330 ofcable 326. The metallic member has an opening through which it is positioned onrod 317. Whenmachine 300 is in usemetallic member 336 may be separate frommagnet 334 such that it bears against outer carriage 16 (FIG. 3C ). When a user operatedmachine 300 by movingarm 322 in the positive movement of a leg curl or leg extension, the pulley system causescable 326 to move such thatmetallic member 336 exerts force toward thebottom end 313 ofhousing 301. This causes metallic member to bear againstouter structure 16.Outer structure 16 flexes againstinner structure 14. Asensor 24 detects this movement and notifiescontroller 22 which instructs motor to turndrive screw 18 in accordance with a program to movecarriage 12 to apply a certain amount of resistance. In the negative portion of the movement,metallic member 336 will exert diminishing force againstinner structure 14.Sensor 24 will detect the diminishing force, notifycontroller 22, which will instruct motor to turndrive screw 18 in the opposite direction and at a certain level of resistance. - When a user no longer wants to user leg curl and leg extension,
metallic member 336 may be moved towardmagnet 334, which will hold it out of the way such that it such that it is no longer in engaged with carriage 12 (FIG. 3D ).Carriage 12 could then be attached to another attachment to perform another exercise. For instance,carriage 12 could be provided with a handle or bar such that a user could perform a press or pulling exercise. In another example,carriage 12 could be provided with a lever as inFIGS. 2A-2C .Machine 300 could then operate as universal weight lifting apparatus including a pulley system and a lever system. - Referring to
FIG. 4 , another embodiment of anexercise machine 400 incorporatingsystem 10 is shown for illustrative purposes.Machine 400 is similar tomachine 300. However, instead of functioning as a leg extension/leg curl machine,machine 400 is configured as a preacher curl machine.Machine 400 includes ahousing 401 having afirst end 403 and asecond end 405. Acarriage 12,drive screw 18,motor 20, andcontroller 22 are positioned within the space defined by thehousing 401. Anarm 407 is rotatably connected tohousing 401 at apivot point 409. Aplatform 411 is provided for users to position their upper arms. Acable 413 includes afirst end 415 connected toarm 407 and asecond end 417 connected toouter structure 16 ofcarriage 12. Apulley 419 redirects cable fromarm 407 such that it movescarriage 12 longitudinally along the line extending fromfirst end 403 to second 405. When a user performs a positive movement by rotating his hands toward his body, thesecond end 417 of the cable 13 will pull againstouter portion 16 ofcarriage 14 and cause it to flex toward thebottom end 405 ofhousing 401. This causesouter structure 16 to flex againstinner structure 14. Asensor 24 detects this movement and notifiescontroller 22 which instructs motor to turndrive screw 18 in accordance with a program to movecarriage 12 to apply a certain amount of resistance. In the negative portion of the movement,outer structure 16 will exert diminishing force againstinner structure 14.Sensor 24 will detect the diminishing force, notifycontroller 22, which will instruct motor to turndrive screw 18 in the opposite direction. - Referring to
FIG. 5 , it should be noted thatcontroller 22 may be implemented on a computing device, an example of which is illustrated inFIG. 5 as a functional block diagram.Computing device 500 may comprise aprocessor 502 and amemory 504 coupled toprocessor 502.Memory 504 may contain executable instructions that, when executed byprocessor 502,cause processor 502 to effectuate operations associated with translating parallel protocols between end points in families as described above. As evident from the description herein,network device 500 is not to be construed as software per se. - In addition to
processor 502 andmemory 504,computing device 500 may include an input/output system 506.Processor 502,memory 504, and input/output system 506 may be coupled together to allow communications between them. Each portion ofcomputing device 500 may comprise circuitry for performing functions associated with each respective portion. Thus, each portion may comprise hardware, or a combination of hardware and software. Accordingly, each portion ofcomputing device 500 is not to be construed as software per se. Input/output system 506 may be capable of receiving or providing information from or to a communications device or other network entities configured for telecommunications. For example input/output system 506 may include a wireless communications (e.g., 3G/4G/GPS) card. Input/output system 506 may be capable of receiving or sending video information, audio information, control information, image information, data, or any combination thereof. Input/output system 506 may be capable of transferring information withnetwork device 500. In various configurations, input/output system 706 may receive or provide information via any appropriate means, such as, for example, optical means (e.g., infrared), electromagnetic means (e.g., RF, Wi-Fi, Bluetooth®, ZigBee®), acoustic means (e.g., speaker, microphone, ultrasonic receiver, ultrasonic transmitter), electrical means, or a combination thereof. Bluetooth, infrared, NFC, and Zigbee are generally considered short range (e.g., few centimeters to 20 meters). WiFi is considered medium range (e.g., approximately 100 meters). - Input/
output system 506 may contain acommunication connection 508 that allowscomputing device 500 to communicate with other devices, network entities, or the like.Communication connection 508 may comprise communication media. Communication media typically embody computer-readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. By way of example, and not limitation, communication media may include wired media such as a wired network or direct-wired connection, or wireless media such as acoustic, RF, infrared, or other wireless media. The term computer-readable media as used herein includes both storage media and communication media. Input/output system 506 also may include aninput device 510 such as keyboard, mouse, pen, voice input device, or touch input device. Input/output system 506 may also include anoutput device 512, such as a display, speakers, or a printer. It should be understood that the various user interfaces described in connection withFIGS. 1A-4 may be implemented as an integrated part of input/output system 506. User interfaces may also be implemented asstandalone devices 500 that are interfaced withcomputing device 500 through input/output system 506. -
Processor 502 may be capable of performing functions associated with to controlsystem 10. For example, processor may operatesystem 10 to provide varying resistance in the machines described inFIGS. 2-4 .Processor 502 may be programmed to provide resistance in accordance with a program defined by a user. A user may comprise a user of exercise equipment, a manufacturer of exercise equipment, or a third party, such as a coach or trainer. -
Memory 504 ofcomputing device 500 may comprise a storage medium having a concrete, tangible, physical structure. As is known, a signal does not have a concrete, tangible, physical structure.Memory 504, as well as any computer-readable storage medium described herein, is not to be construed as a signal.Memory 504, as well as any computer-readable storage medium described herein, is not to be construed as a transient signal.Memory 504, as well as any computer-readable storage medium described herein, is not to be construed as a propagating signal.Memory 504, as well as any computer-readable storage medium described herein, is to be construed as an article of manufacture. -
Memory 504 may store any information utilized in conjunction with operating thesystem 10 and the exercise equipment shown inFIGS. 2-5 as well as variations thereof. Depending upon the exact configuration or type ofprocessor 502,memory 504 may include a volatile storage 514 (such as some types of RAM), a nonvolatile storage 516 (such as ROM, flash memory), or a combination thereof.Memory 504 may include additional storage (e.g., aremovable storage 518 or a non-removable storage 520) including, for example, tape, flash memory, smart cards, CD-ROM, DVD, or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, USB-compatible memory, or any other medium that can be used to store information and that can be accessed by computingdevice 500.Memory 504 may comprise executable instructions that, when executed byprocessor 502,cause processor 502 to provide varying resistance in an exercise machine. - While examples of systems and methods for providing varying resistance have been described in connection with various machines, computing devices/processors, the underlying concepts may be applied to various equipment that have not been described, but which are within the scope of this disclosure. The various resistance programs described herein may be implemented in
controller 22 with hardware or software or, where appropriate, with a combination of both. Thus,controller 22 may take the form of program code (i.e., instructions) embodied in concrete, tangible, storage media having a concrete, tangible, physical structure. Examples of tangible storage media include floppy diskettes, CD-ROMs, DVDs, hard drives, or any other tangible machine-readable storage medium (computer-readable storage medium). Thus, a computer-readable storage medium is not a signal. A computer-readable storage medium is not a transient signal. Further, a computer-readable storage medium is not a propagating signal. A computer-readable storage medium as described herein is an article of manufacture. When the program code is loaded into and executed by a machine, such as a computer, the machine becomes a device for providing varying resistance. In the case of program code execution on programmable computers, the computing device will generally include a processor, a storage medium readable by the processor (including volatile or nonvolatile memory or storage elements), at least one input device, and at least one output device. The program(s) can be implemented in assembly or machine language, if desired. The language can be a compiled or interpreted language, and may be combined with hardware implementations. - The methods and devices associated
controller 22 may be practiced via communications embodied in the form of program code that is transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as an EPROM, a gate array, a programmable logic device (PLD), a client computer, or the like, the machine becomes an device for implementing telecommunications as described herein. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique device that operates to invoke the functionality ofcontroller 22. - Referring to
FIG. 6 , an exemplary method 600 for operatingsystem 10 is now described for illustrative purposes. In step 601, user input is received. User input in one example may be provided throughinput output system 506 described in connection withFIG. 5 . User input may include a number of characteristics of user. For example, user input may include the height and weight of a user. User input may include data indicative of a user's strength. For instance, if a user is capable of performing a 500 pound squat or a 200 pound press. User input may include one or more exercise modes that that the user would like to perform. For instance, a user may specific that the user would like to operate an exercise machine at a particular varying resistance. One example would be that the user would like to perform a selected movement at a certain resistance during the positive portion of the movement and a resistance equal to 120% of that resistance during the negative portion of the movement. Another example would be that the user would like to perform the a movement at certain resistance at the beginning of a positive portion of a movement and would like the resistance to increase as the user is performing the positive portion of the movement. In another example, the user may indicate that the user would like resistance to vary during the range of a negative portion of a movement. In another example, a user may specify that the user intends to perform a number of repetitions and the user would like resistance to vary from repetition to repetition. In one example, user input may be provided at the time the user begins to use system 100. In another example user input may be preprogrammed intosystem 10 and stored. In such an example, the user may have a profile that the user could access and select such preprogrammed input for use in a workout. - Referring further to
FIGS. 1A-1B andFIG. 6 , in one example, controller determines whether or not a user's input corresponds to an operational mode. An operational mode may comprise a predetermined mode of operation. The operational mode may be to instructmotor 20 to turn drive screws such thatcarriage 12 would move freely in whatever direction the user moves it. In another example, the operation mode may be a predetermined resistance program in which case thecontroller 22 would instruct motor to operate in accordance with the resistance program. In another example, the operational mode may be to provide straight resistance. For example, the user could request 100 lbs. of resistance in which case thecontroller 22 would instructmotor 20 to rotate in a direction and at an amount of torque equal to 100 lbs. of resistance. In another example, the operational mode may be an isometric mode in which user would specify that it does not want carriage to move. Accordingly,controller 22 would operatemotor 20 so that it remained fixed. - Referring further
FIG. 1 andFIG. 6 , instep 605, if it is determined that the user has selected an operation mode, then instep 607, thesystem 10 runs the operational mode. If instep 605, it is determined that the user has not selected an operational mode, then instep 609,system 10 may suggest an operational mode or enter into a default operational mode. System may provide output to user throughinput output system 506 describe in connection withFIG. 5 .
