Description

TECHNICAL FIELD

The present disclosure relates to exercise equipment. More particularly, the present disclosure relates to strength training equipment including a flywheel and to related methods.

BACKGROUND

While there are numerous exercise activities that one may participate in, exercise may be broadly broken into the categories of aerobic exercise and anaerobic exercise. Aerobic exercise generally refers to activities that substantially increase the heart rate and respiration of the exerciser for an extended period of time. This type of exercise is generally directed to enhancing cardiovascular performance. Such exercise usually includes low or moderate resistance to the movement of the individual. For example, aerobic exercise includes activities such as walking, running, jogging, swimming or bicycling for extended distances and extended periods of time.

Anaerobic exercise generally refers to exercise that strengthens skeletal muscles and usually involves the flexing or contraction of targeted muscles through significant exertion during a relatively short period of time and/or through a relatively small number of repetitions. For example, anaerobic exercise includes activities such as weight training, push-ups, sit-ups, pull-ups or a series of short sprints.

When exercising at home or in a gym, aerobic and anaerobic exercise usually involves the use of different types of equipment. For example, aerobic exercise usually involves equipment such as treadmills, ellipticals and bicycles (traditional and stationary) while anaerobic exercise often involves the use of free weights, weight stacks, or other cable and pulley resistance-type systems.

Often, individuals will plan their work-out routines to include both aerobic and anaerobic activities. For example, a person may do anaerobic exercises (e.g., weight lifting and other strength training exercises) on two or three days of the week while doing aerobic exercising (e.g., running, bicycling) on the remaining days of the week. In other instances, an individual may do both aerobic and anaerobic activities during the same day.

One of the difficulties in integrating both aerobic and anaerobic activities is the ability of an individual to efficiently and effectively track their progress. For example, many individuals use aerobic exercise equipment such as a treadmill or an elliptical machine to automatically track the calories that they've burned while using such equipment. However, it is more difficult to track or calculate such information when doing strength training exercises.

A couple of examples of equipment that has tried to combine aerobic exercising with anaerobic exercising are described in U.S. Pat. No. 5,527,245 to Dalebout et al. and U.S. Pat. No. 7,740,563 to Dalebout et al. These patents describe a resistance-type strength training apparatus combined with, in one instance, a treadmill, and in another instance an elliptical device.

In view of the foregoing, it would be desirable to provide the ability to track one's progress during exercise in a manner that is applicable to both aerobic and anaerobic activities and which is simple and effective. Additionally, it is a general desire in the industry to provide exercise equipment with new features and enhanced performance.

DETAILED DESCRIPTION

Referring to FIGS. 1-3, a strength training apparatus 100 is provided. The apparatus 100, according to certain embodiments, includes a base member 102 and a tower 104 or support structure coupled to, and extending upward from, the base member 102. The base may be configured to include a plurality of legs 106A-106C extending away from each other to provide a stable base or platform for the apparatus 100 and to support the apparatus 100 when forces are applied to it by someone using the apparatus 100 to exercise. In the embodiment shown in FIGS. 1-3, the base member 102 includes three legs. However, it is noted that other configurations are contemplated.

A pair of arms 108A and 108B are pivotally coupled to the tower 104 by way of a bearing 110 or other mechanical structure. The bearing 110 enables the arms 108A and 108B to rotate about a defined axis 112 (FIGS. 2 and 3) relative to the tower 104 and base member 102 as indicated by directional arrow 113 (FIG. 1). In one embodiment, the arms 108A and 108B may be configured to maintain a constant angular relationship relative to each other as they are rotated about the axis 112 (e.g., they may continually extend in substantially opposite directions from each other). In another embodiment, each arm 108A and 108B may be selectively positionable (manually, or by a motor or other actuator (not shown)) independent of the other so that they may be positioned at any of a variety of angles relative to each other.

The apparatus 100 also includes a pair of pulleys 114A and 114B, one being pivotally coupled to the end of each arm 108A and 108B. Cables 116A and 116B extend through each pulley 114A and 114B and are coupled with handles 118A and 118B. As will be described in further detail below, the handles 118A and 118B, the cables 116A and 116B and the pulleys 114A and 114B are part of a cable/pulley system that provides resistance to an individual that is using the apparatus 100 for strength training.

As seen in FIGS. 2 and 3, a flywheel 120 is coupled to either the base member 102 or the tower 104 (or to both) and configured to rotate about a shaft 122. A resistance or braking mechanism 124 is positioned adjacent the flywheel 120 and is selectively adjustable so as to apply a desired level of resistance to the rotation of the flywheel 120. Various types of braking mechanisms may be used including, in one embodiment, straps or pads that apply friction to the flywheel 120. In one embodiment, a magnetic brake (sometimes referred to as an eddy current brake) may be used to provide an adjustable level of resistance applied to the flywheel 120.

When the braking mechanism 124 is configured as a magnetic mechanism it may include an arm 126 that is pivotally coupled with the tower 104 and which contains a plurality of magnets arranged to provide a desired magnetic flux. As the arm 126 is rotated relative to tower 104 (and, thus, the flywheel 120), the magnetic flux through which the flywheel 120 rotates changes, thereby altering the amount of rotational resistance experienced by the flywheel 120.

The flywheel 120, when configured to interact with a magnetic braking mechanism, may include ferrous components, non-ferrous components, or both. In one embodiment, the flywheel 120 may include a relatively dense ferrous component to impart a desired level of rotational inertia to the flywheel 120. The flywheel 120 may also include a nonferrous component to provide increased braking resistance when used with a magnetic brake mechanism. For example, one embodiment may include a portion that is formed of cast iron (a ferrous material) to provide the desired rotational inertia with another portion formed of an aluminum material (to provide increased braking response to the magnetic mechanism). One such configuration of a flywheel, as well as an associated magnetic braking mechanism, is described by U.S. Patent Application Publication No. 2012/0088638 to Lull (application Ser. No. 13/267,719), the disclosure of which is incorporated by reference herein in its entirety.

A torque sensor 128 may be associated with the shaft 122 to determine the amount of torque applied to the flywheel 120 by a drive mechanism (discussed below). Various types of torque sensors may be utilized. One example of a torque sensor includes that which is described in U.S. Pat. No. 7,011,326 to Schroeder et al., the disclosure of which is incorporated by reference herein in its entirety. Another example of a torque sensor includes that which is described in U.S. Pat. No. 7,584,673 to Shimizu, the disclosure of which is incorporated by reference herein in its entirety.

The apparatus further includes a control panel 130 which may be located adjacent the bearing 110 or some other convenient location (e.g., on the tower 104). The control panel 130 may include various input devices 132 (e.g., buttons, switches or dials) and output devices 134 (e.g., LED lights, displays, alarms) to provide means of interaction with a user of the apparatus 100. The control panel 130 may further include connections for communication with other devices. The controller may include a processor and memory to provide various functions in controlling components of the apparatus 100 (e.g., the braking mechanism), in communicating with various components (e.g., the torque sensor) and making certain calculations as will be discussed below.

In one example, one of the input devices 132 of the control panel 130 may be used to set a desired resistance level that is to be applied to the flywheel 120 by controlling an actuating member associated with the braking mechanism 124. An output device 134 (e.g., a display) may indicate the current or selected level of resistance. An output device 134 of the control panel 130 may also provide an indication of the amount of work performed within a period of time calculated, for example, based on the torque applied to the flywheel 120 as measured by the torque sensor 128.

Referring now to FIGS. 4A and 4B, a side view and a rear view of the apparatus 100 is shown with various components which may be disposed within the tower 104 or otherwise arranged to assist in driving flywheel 120. It is noted that FIG. 4B does not depict the arms 108A and 108B (and associated components) for purposes of clarity and convenience. A drive mechanism 140 may include a clutch mechanism 142 having an input shaft 144 and an output shaft 146. A drive belt 148 (or drive chain or other similar drive structure) may extend about the output shaft 146 and also about the shaft 122 of the flywheel 120 (or associated pulleys coupled with the shafts). The clutch mechanism 142 is configured such that, when the input shaft 144 is rotated in a first specified direction, the output shaft 146 is likewise rotated in a specified direction displacing the drive belt 148 and, ultimately, driving the flywheel 120 in a desired direction. However, if the input shaft 144 is rotated in a second direction, opposite that of the first direction, it has no effect on the output shaft 146. Rather, the output shaft 146 is enabled to continue rotating in its initially specified direction and does not reverse directions. It is noted that, in other embodiments, the clutch mechanism 142 may be coupled directly to the flywheel 120.

A drive chain 150 (or drive belt or cable or other appropriate structure) has a first end 152 that is coupled to the cables 116A and 116B that extend through pulleys 114A and 114B and either extend through, or adjacent to, the arms 108A and 108B. The drive chain 150 extends through several pulleys or sprockets including, for example, a first sprocket 154, the input shaft 144 (or an associated pulley or sprocket coupled therewith) and a second sprocket 156. A second end 158 of the drive chain 150 may be fixed, for example, to a frame or other component associated with the tower 104. In the embodiment shown in FIGS. 4A and 4B, the first sprocket 154 is rotatable about an axis which is fixed relative to the tower 104. The second sprocket 156 is rotatable about an axis which is displaceable relative to the tower 104. For example, one or more biasing members 160 may be coupled between the second sprocket 156 and the tower 104 (or some component thereof) enabling the second sprocket 156 to be displaced relative to the tower 104. Guide members may be used to help constrain or control the displacement of the sprocket along a desired path.

Referring briefly to FIGS. 5A and 5B, views similar to those depicted in FIGS. 4A and 4B, respectively, show certain components in a second position or state. Specifically, FIG. 5A depicts the displacement of a handle 118A due to application of a force by an individual during exercise. Displacement of the handle 118A results in displacement of the associated cable 116A and, ultimately, displacement of the drive chain 150. As indicated in FIG. 5A, a first portion of the drive chain 150 is displaced upwards towards the first sprocket 154 as indicated by directional arrow 170 while a second portion of the drive chain 150 is displaced downwards away from the second sprocket 156 and towards the input shaft 144 as indicated by directional arrow 172. It is noted that this displacement of the drive chain 150 also includes the downward displacement of the second sprocket 156 against the force of the biasing members 160 as seen in both FIGS. 5A and 5B. The displacement of the drive chain 150 results in the rotation of the input shaft 144, actuating the drive mechanism 140 such that the drive belt 148 drives the flywheel 120.

Upon release of the force applied to the handle 118A, the biasing members 160 pull the second sprocket 156 back to its previous position bringing the various components (e.g., drive chain 150, cable 116A and handle 118A) back to the positions shown in FIGS. 4A and 4B. However, as noted above, the return of the drive chain 150 to its previous position does not cause the flywheel 120 to rotate in the opposite direction or otherwise hinder its continued rotation due to the directional preference of the clutch mechanism 142. It is noted that, while the example shown in FIGS. 5A and 5B is described in terms of one particular handle (i.e., 118A) being displaced, the same functionality applies to the displacement to the other handle (i.e., 118B) or to both of them being substantially simultaneously displaced.

INDUSTRIAL APPLICABILITY

During exercise, many individuals desire to focus on anaerobic strength training, or to integrate anaerobic strength training with aerobic work-outs. One of the difficulties in mixing both aerobic and anaerobic activities is the ability of an individual to efficiently and effectively track their progress. For example, many individuals use aerobic exercise equipment such as a treadmill, an elliptical machine or a pedometer to help track the calories that they've burned while using such equipment. However, it is more difficult to track or calculate such information when doing strength training type of exercises.

The exercise apparatus provided herein provides a strength training apparatus that enables a variety of exercises while also providing the ability to track the work performed by an individual during their exercise session. By positioning the adjustable arms at different locations relative to the tower, different types of exercises may be conducted. For example, due to the adjustability of the arms/pulleys, the exercise apparatus may be used to perform exercises including, but not limited to, standing abdominal crunches, curls and other bicep exercises, lat pull-downs, chest presses, incline and decline presses, overhead presses, triceps extensions, shoulder extensions, leg extensions, leg curls, abduction and adduction exercises, and a variety of other exercises, including variations of the examples provided.

Additionally, the use of a flywheel in connection with a strength training apparatus provides a different form of resistance than in conventional strength training exercises, one that can be measured, tracked and incorporated into a planned exercise routine. The flywheel, combined with a braking mechanism such as a magnetic brake, enables considerable flexibility in setting the desired resistance during exercise. In many conventional strength training exercises, the amount of resistance provided (e.g., by free weights, weight stacks or resistance bands) is only adjustable in set increments (e.g., 5 or 10 pound increments). The use of a flywheel with a variable resistance braking mechanism enables fine tuning of the resistance over a continuous spectrum between two defined limits.

The use of a torque sensor in conjunction with the flywheel enables the calculation of work, power or energy so that, for example, a user of the apparatus may determine their performance level while using the exercise apparatus. In one particular example, the power expended during an exercise session may be expressed in watts (i.e., joules/sec (J/s) or newton meters I sec (N*m/s). A user of the machine can review the power expended during an exercise session from a display (or other output device) associated with the exercise apparatus and then compare their performance to a goal or a benchmark.

Such a way of tracking the effort expended during an anaerobic exercise routine provides more insight into the progress of the individual than just the number of repetitions completed during a given work-out session. If desired, other units may be utilized to track the energy expended by an individual during a work-out session. For example, rather than expressing the work-out performance in terms of watts (units of power), it could be expressed in terms of joules (units of work).

This information could be used with information from other work-out activities, including aerobic exercise, to consistently monitor the performance of an individual over a desired period of time. For example, rather than expressing the performance of an individual on a treadmill or an elliptical machine in terms of calories, those performances may similarly be provided in terms of watts (or another selected unit) so that all types of exercise activity may be monitored uniformly. An individual may then customize their exercise routine based, for example, on the amount of work that is to be performed regardless of whether that work occurs during an aerobic or an anaerobic activity.

One example of customizing a work-out that may be utilized in conjunction with the exercise apparatus described herein is set forth in U.S. patent application Ser. No. 13/754,361, filed on Jan. 30, 2013, which published on Aug. 1, 2013 as U.S. Patent Application Publication No. US 2013/0196821 A1 (“the '821 Publication”), the disclosure of which is incorporated by reference herein in its entirety. One particular example of tracking a work-out across various exercise equipment and which may be utilized in conjunction with the exercise apparatus described herein is set forth in U.S. Pat. No. 6,746,371 to Brown et al., the disclosure of which is incorporated by reference herein in its entirety.

For example, FIG. 1 of the '821 Publication illustrates a block diagram of one embodiment of an environment 100 in which the present systems and methods may be implemented. In one configuration, an exercise apparatus 102 may exchange information with a client computing device 106. The client computing device 106 may acquire the information from the apparatus 102. For example, the information may be embedded as a data exchanging module 104 that is included on or by the exercise apparatus 102. Examples of the data exchanging module 104 may include, but are not limited to, barcodes, QR codes, RF tags, etc. The module 104 may be affixed or attached to an area of the apparatus 102 or an area that is not on the apparatus 102 (e.g., a wall close to the apparatus 102). The client computing device 106 may include a data sensing module 108 that is able to sense the data exchanging module 104. For example, the sensing module 108 may provide scanning capabilities that allows the device 106 to scan the data exchanging module 104 to obtain information about the apparatus 102. For example, the data exchanging module 104 may be a barcode and the data sensing module 108 may be a barcode scanner. In another embodiment, the data exchanging module 104 and the data sensing module 108 may include near field communication (NFC) capabilities. As a result, using NFC standards, a radio communication link may be established between the apparatus 102 and the device 106. The client computing device 106 may acquire the information from the exercise apparatus 102 via the radio communication link. The apparatus 102 and the device 106 may exchange information via other methods in addition to bar codes, QR codes, and NFC technologies.

Examples of the exercise apparatus 102 may include a weight machine (e.g., a fly machine, a leg press machine, a leg curl machine, a leg extension machine, a cable lateral pull-down machine, a triceps pull-down machine, a row machine, etc.). The exercise apparatus 102 may also be a free weight, such as a dumbbell, a medicine ball, an exercise ball, a bench press, etc. In another embodiment, the exercise apparatus 102 may be a cardio machine (e.g., a treadmill, a stationary bike, a spinner bike, a stair machine, etc.).

In one embodiment, the client computing device 106 may be a smartphone, a laptop, a tablet, or any other portable computing device. In one configuration, the client computing device 106 may be any device that is able to detect, receive, and interpret the data acquired from the data exchanging module 104. To interpret the received data, the client computing device 106 may communicate with a server 112 across a network 110 connection. The network 110 connection may be a Wi-Fi, a wireless local area network (WLAN), a cellular network, and the like. The server 112 may communicate with an exercise apparatus database 114. The database 114 may be external to the server 112, or the database 114 may be built into the server 112. In one embodiment, the exercise apparatus database 114 may store information regarding the exercise apparatus 102. For example, the database 114 may store instructions that indicate how to properly use the exercise apparatus 102. The database 114 may also store videos that demonstrate how to use the apparatus 102. In one example, the client computing device 106 may acquire information from the apparatus, such as an identifier that identifies the apparatus 102. The identifier may be communicated to the server 112. The server 112 may use the identifier to locate additional information in the database 114 about the apparatus 102. The server may communicate the additional information about the apparatus 102to the computing device 106. In one embodiment, the data exchanging module 104 may include the additional information that is stored in the database 114. As a result, when the computing device 106 acquires the information from the apparatus 102, there may be no need for the client 106 to communicate with the server 112 to acquire the additional information.

FIG. 2 of the '821 Publication is a block diagram illustrating one embodiment of a client computing device 106-a. The client computing device 106-a may be an example of the client computing device 106 illustrated in FIG. 1 of the '821 Publication. In one example, the client computing device 106-a may include a data sensing module 108-a. In one configuration, the module 108-a may include a QR code module 202, a barcode reading module 204, an NFC module 206, a profile module 208, a customized workout module 210, and a tracking module 212. Details regarding each of these modules will be described below.

In one embodiment, the QR code module 202 may sense data affixed to or by the exercise apparatus 102 that is encoded as a QR code. Similarly, the barcode reading module 204 may sense data embedded or encoded as a barcode that may be attached to or near the exercise apparatus 102. The modules 202 and 204 may sense the data by scanning the QR code or the barcode that is attached to the exercise apparatus 102. The NFC module 206 may establish a radio communication link with the exercise apparatus 102. The NFC module 206 may acquire data from the exercise apparatus 102 via the radio communication link.

In one configuration, the profile module 208 may receive and store input from a user relating to the user's profile information. Examples of profile information may include the user's age, height, weight, etc. The profile module 208 may further receive and store input from the user relating to physical fitness goals of the user. Examples of physical fitness goals may include a desired weight loss, strength conditioning goals, target heart rate goals, running/walking distance goals, specific muscle definition goals etc. The customized workout module 210 may receive the data sensed from the modules, 202, 204, and/or 206. The workout module 210 may also receive information stored by the profile module 208. In one embodiment, the workout module 210 may generate a customized workout routine for the user to perform with the exercise apparatus 102 in order to progress towards achieving the physical fitness goals stored in the profile module.

As an example, the client computing device 106-a may receive data relating to the exercise apparatus 102. The data may indicate the name of the apparatus 102, the functions of the exercise apparatus 102, instructions on how to properly use the exercise apparatus 102, the muscle group focused on by the exercise apparatus 102, the health benefits of using the apparatus 102, video or other multimedia data that demonstrate how to use the apparatus 102, etc. The data may be received directly from the data exchange module 104 affixed to the apparatus 102 and/or from the server 112 that obtains the data from the database 114 and communicates the data to the client computing device 106. The customized workout module 210 may analyze the received data about the exercise apparatus 102 together with the information stored by the profile module 208. Based on this analysis, the customized workout module 210 may generate a workout routine for the user to perform with the exercise apparatus 102. The generated workout routine may be focused on helping the user accomplish one or more physical fitness goals stored by the profile module 208. For example, the user may specify a physical fitness goal of bench pressing 200 lbs. The profile module 208 may also include information that indicates that the user is currently able to bench 160 lbs. The user may then approach a chest fly machine with the client computing device 106-a. A barcode may be affixed on a portion of the machine. The computing device 106-a may scan the barcode and obtain data about the machine. As stated above, the data may be acquired from scan of the barcode and/or from the server 112. For example, the client 106-a may scan the barcode and retrieve the identity of the machine (in this example, a chest fly machine). The identity may be transmitted to the server 112. The server 112 may use the received identity to search the database 114 for data about the machine. The server 112 may then communicate the data back to the client computing device 106-a.

The data (either obtained directly from the exercise apparatus 102and/or from the server 112) may indicate that the chest fly machine focuses on certain chest muscles. The data may also include a video demonstration that illustrates how to properly use the chest fly machine. The customized workout module 210 may generate a workout routine (e.g., number of repetitions, sets, and the weight resistance) for the user to follow when using the chest fly machine. The routine may be generated based on an analysis of the information stored by the profile module 208 as well as the data acquired from the exercise apparatus (directly and/or indirectly from the server 112). The workout routine may be customized for the user to assist the user to accomplish the physical fitness goal(s) included in the profile module. As a result, the workout routine, if followed by the user, may assist the user to accomplish the goal of bench pressing 200 lbs.

In one example, the profile module 208 may not include physical fitness goal information that relates to a certain exercise apparatus 102. For instance, the sensing module 108-a may acquire information relating to a treadmill by scanning a barcode, QR code, etc. The customized workout module 210 may analyze the profile module 208 and discover that the user has not entered a goal that may be accomplished by using the treadmill.

For example, the module 210 may display the following query “Do you want to set a goal to run 3 miles in 30 minutes?” If the user selects this goal, the workout module 210 may continue to generate a customized workout routine for the user to assist the user to complete this goal. Instead of selecting a goal generated by the customized workout module 210, the user may provide his/her own goal as it relates to the treadmill. Once the goal is provided, the module 210 may generate a customized workout routine.

The tracking module 212 may track the progress of the user while the user is using the exercise apparatus 102. For example, the tracking module 212 may be a camera or other tracking device that is capable of monitoring the movement of the user. The tracking module 212 may also track the progress of the user towards completing the goals specified in the profile module 208. For example, the profile module 208may include a goal to lose 20 lbs. The tracking module 212 may track the weight of the user to allow the user to see his/her progress towards achieving the goal of losing 20 pounds. In one example, the user may manually enter his/her weight into the tracking module 212. In another embodiment, the tracking module 212 may track the progress of the user by receiving automatic updates via email, SMS messages, and the like that include the current state of the user. For example, the user may visit a website and record his/her weight on the website. The website may communicate with the tracking module 212 to provide the updated weight of the user.
