20230226401
A cable exercise machine is a popular piece of exercise equipment for improving muscular definition and strength. Some benefits of a cable exercise machine are that it may enable a user to easily isolate muscles. However, use of a cable exercise machine may result in individual muscles becoming stronger while other muscles are left weak. This may be due to the cable exercise machine adjusting, balancing, and supporting the user’s body, resulting in weaker muscles that would normally do these tasks in real life.
Free weights are also popular for improving muscular definition and strength. Incontrast to using a cable exercise machine, using free weights tends to require a user to use morethan one muscle group for each exercise, and may generally result in less muscle isolation.

The exercise machine may also include certain bottom-out features that prevent the cables from being fully extended in order to maintain the effective assistance of the cables while pulling on the cables alone or when the cables are attached to the barbell. In this manner, the example exercise machine disclosed herein may enable a user to perform both cable exercises as well as free weight exercises.
Turning now to the drawings, 1A-1E are front-right, front, right, rear, and top views, respectively, of an example cable and power rack exercise machine. The exercise machine 100 may include a frame 102, a resistance mechanism 104 supported by the frame 102, and pull cables 106a-106f supported by the frame 102 and linked to the resistance mechanism 104, and a power rack 108 attached to the frame 102.
The frame 102 may be supported by a base that may include left and right legs 110a and 110b and left and right lower supports 112a and 112b. The frame may also include left and right upper supports 114a and 114b.
The resistance mechanism 104 may include a flywheel 116 and one or more magnets 118 arranged to selectively resist rotation of the flywheel 116 (which may be either permanent magnets configured to be repositioned or electromagnets configured to have magnetic strength adjusted). The pull cables 106a-106f may have handles 120a-120f attached thereto, respectively, such that a user can pull on any of the pull cables 106a-106f by pulling on the corresponding handle 120a-120f. The pull cables 106a-106f may be linked to the resistance mechanism 104, via multiple pulleys, spools, other cables, etc., such that the resistance mechanism 104 can apply a set level of resistance to a user pulling on any one of the pull cables 106a-106f. The level of resistance applied by the resistance mechanism 104 may be at least partially controlled by a console 122, and/or may be at least partially controlled by a tablet 124a or 124b that is in wired or wireless communication (e.g., Bluetooth communication) with the console 122.
The pull cables 106a-106f may be further linked to left and right tensioner springs 125a and 125b that are configured to reduce slack in the pull cables 106a-106f. More particularly, the left tensioner spring 125a may be configured to reduce slack in the left-side pull cables 106a, 106c, and 106e, while the right tensioner spring 125b may be configured to reduce slack in the right-side pull cables 106b, 106d, and 106f. For example, after a user pulls on one of the pull cables 106a-106f, the left tensioner spring 125a or the right tensioner spring 125b may be configured to retract the pull cable back to its fully-retracted position.
The power rack 108 may include left and right upright posts 126a and 126b that are attached to the frame 102 via the left and right lower supports 112a and 112b and the left and right upper supports 114a and 114b, respectively. The left and right upright posts 126a and 126b may be configured to have left and right barbell holders 128a and 128b, respectively, adjustably attached thereto. The left and right barbell holders 128a and 128b may be adjusted in various positions between left and right highest positions 130a and 130b and left and right lowest positions 132a and 132b on the left and right upright posts 126a and 126b, respectively. The left and right upright posts 126a and 126b may be configured to have left and right spotter arms 134a and 134b,respectively, adjustably attached thereto. The left and right spotter arms 134a and 134b may alsobe adjusted in various positions between the left and right highest positions 130a and 130b and the left and right lowest positions 132a and 132b on the left and right upright posts 126a and 126b, respectively. The left and right barbell holders 128a and 128b and/or the left and right spotter arms 134a and 134b may be configured to prevent a barbell 135 from falling on a user if the user is unable to continue lifting the barbell 135.
The power rack 108 may further include a pull-up bar 136 supported by the left and right upright posts 126a and 126b. The pull-up bar 136 may be configured to allow a user to perform pull-ups on the power rack 108. The power rack 108 may further include left and right upper pulleys 138a and 138b supported by the pull-up bar 136 and left and right lower pulleys 140a and 140b supported by the left and right legs 110a and 110b, respectively. The power rack 108 may further include left and right weight plate holders 142a and 142b supported by the left and right upright posts 126a and 126b configured for storage of weight plates, such as the weightplate 143. The power rack 108 may further include dumbbell racks 144a-144d supported by the frame 102 and each configured to hold a dumbbell (not shown).
The exercise machine 100 may further include a tablet holder 146 configured to hold the tablet 124a, or to hold a second tablet 124b, so that when the user is faced away from the console 122, and/or from the tablet 124a mounted above the console 122, the user may continue to view a tablet connected to the console 122 of the exercise machine 100, and to control the exercise machine 100 using the tablet, without having to turn around.
The exercise machine 100 may further include a barbell retention device (see
The exercise machine 100 may further include a bottom-out mechanism configured to prevent the pull cables 106a-106f from being fully extended, also known as bottoming-out or dead- ending. For example, this bottom-out mechanism may include left and right sensors 148a and 148b positioned on the left and right legs 110a and 110b, respectively. The left and right sensors 148a and 148b may include one or more of an optical sensor, a magnetic sensor, a camera sensor, or aninfrared sensor, or some other sensor. The left and right sensors 148a and 148b may be configured to trigger when any of the pull cables 106a-106f has been extended to within a threshold of being fully extended (e.g., within 2 feet of being fully extended), when a user has moved past a threshold distance from the exercise machine 100 (such as past the line 150), or when a barbell (such as the barbell 135, which may be a standard Olympic 44-pound or 45-pound barbell) has moved past a threshold distance (such as past the line 150) from the exercise machine 100, among other triggering events. In response to the triggering of the left and right sensors 148a and 148b, an alarm may alert the user of a danger of any of the pull cables 106a-106f being fully extended, or the danger of some other event.
In general, the example exercise machine disclosed herein may combine features of a cable machine and features of a power rack to yield a superior exercise machine where a user canperform cable workouts, free weight workouts, or combined workouts. In a combined workout, the cables of the exercise machine may be attached to a barbell to assist the user in performing a workout with the barbell by either making the barbell easier to lift or harder to lift, depending on the desired effect. The exercise machine may also include certain bottom-out features that prevent the cables from being fully extended in order to maintain the effective assistance of the cables, while pulling on the cables alone, or when using the cables while attached to the barbell.
The exercise machine disclosed herein may be employed to perform a high-intensity lifting workout, a cardio building workout, or a high intensity interval training (HIIT) workout, orsome combination thereof. The exercise machine may be employed at a gym or in a home setting.
Various modifications to the example exercise machine disclosed above will now be disclosed.
Although the example exercise machine disclosed herein includes six pull cables, in some embodiments as few as two pull cables or more than six pull cables may be included. Further, pull cables may be positioned at positions other than those illustrated in the drawings.
Further, although tensioner springs are disclosed herein, in some embodiments the tensioner springs may be replaced with any other mechanism that is configured to reduce slack inpull cables, such as elastic cords, counterweights, or other types of springs. In these embodiments, the other mechanism that is configured to reduce slack in pull cables may continue to function as described above in connection with the barbell to either make lifting the barbell easier to lift or harder to lift, depending on the desired effect.
Also, although the resistance mechanism disclosed herein includes a flywheel and one or more magnets arranged to selectively resist rotation of the flywheel, in some embodiments the resistance mechanism may instead include another type of brake (with or without a flywheel), a motor, weights, or other structure(s) capable of providing resistance to pull cables linked thereto. In the case of a motor, the resistance mechanism may double as both a resistance mechanism as well as a mechanism that affirmatively pulls on the pull cables with a set amount of force. In thiscase, the motor may be attached to a barbell, and may be controlled by a console or other controller to pull on the barbell pull cable(s) upon a command (e.g., a verbal command) of a user, or upon a torque sensor, motion sensor, or other sensor noticing that the user is unable to lift the barbell without some assistance, thus functioning as a virtual spotter to assist the user in lifting the barbell and thus replacing a human spotter. Further, where the resistance mechanism is used to make lifting the barbell harder, the console may be configured to control the resistance mechanism such that the resistance on the barbell gets progressively harder, or progressively easier, to enhance the lifting of the barbell. For example, the resistance mechanism can be controlled to assist a user in lifting the barbell during the final few reps in a set. Alternatively, or additionally, the resistance mechanism can be controlled to provide progressive resistance by providing a digital chain that increases the resistance on the barbell with each lift.
Further, although the bottom-out mechanism disclosed herein includes sensors positioned on left and right legs of the exercise machine, in some embodiments the bottom-out mechanism sensors may be positioned anywhere else on the exercise machine or may be positioned on a separate device in communication with the console of the exercise machine. Further, although the bottom-out mechanism disclosed herein includes sensors, in some embodiments the sensors may be replaced with visual indicators on the pull cables themselves, such as where a pull cable transitions from one color to another, or has another visual marking, when the cable is within a threshold (e.g., within 2 feet) of being fully extended. Also, the bottom-out mechanism disclosed herein may further include one or more brakes configured, in response to a sensor triggering, to engage the pull cables to prevent the pull cables from being extended past some threshold of being fully extended. This brake may prevent a user from pulling a pull cabletoo far away from the exercise machine.
Also, although the console disclosed herein is discussed as having functionality capableof adjusting the resistance on the resistance mechanism, in some embodiments the console may further be configured with computer functionality to receive input from the user and provide output to the user, and/or configured to control the exercise machine. For example, the console may be employed in connection with the resistance mechanism discussed above in order to allow the user to manually or programmatically alter the amount of resistance that the resistance mechanism applies during the course of a workout on the exercise machine. The console may be configured to communicate over a network (e.g., a Bluetooth network, a Wi-Fi network, or the Internet) with other similar exercise machines, with servers, with computing devices of personal trainers, and with sensors such as heart rate and respiration sensors, etc. Further, the console may be capable of downloading and uploading data in order to, for example, download and upload workouts, data gathered at the exercise machine, and data gathered at other exercise machines, etc. The console may enable a user of the exercise machine to compete with a user of another similar or dissimilarexercise machine, that is local to or remote from the user, with the competing users competing inreal-time or at different times. Further, the console may be configured to track the amount of resistance provided by the resistance mechanism, and the number or rotations of the flywheel, during a workout in order to compute the number of calories burned, the amount of energy expended, the amount of work performed, or any other metric or statistic desired by the user. Further, the console may be configured to track the number of cable pulls, the number of barbell lifts and weight lifted, the number of dumbbell lifts and weight lifted, and any other exercise performed in connection with the exercise machine in order to track the number of calories burned, the amount of energy expended, the amount of work performed, or any other metric or statistic desired by the user during a workout using the exercise machine. Further, all data tracked or downloaded by the console may be presented to the user on a display of the console or on a display of another device, such as a tablet or smartphone that is connected via Bluetooth with the console. Further, the console, or another device connected to the console, may be configured to guide a user through a workout using the exercise machine. This guidance may be audible guidance, visual guidance, or some combination of the two, including guidance that employs video depicting exactly what a user should do to follow the workout. In this manner, a user can have the benefit of a trainer without a human trainer present. Further, this guidance may include using lasers or other projected visual indicators to assist a user in performing a workout properly. For example,lasers may be employed to show a user where to place their feet, to show a user how far to pull a pull cable, to show a user how to properly position their hips, knees, joints, head, shoulders, or any other body part to properly perform a cable or free weight exercise. Further, the console may be configured to function as a real-time live video interface to a human trainer who can guide a userthrough a workout on the exercise machine without the human trainer being present. Further, liveor pre-recorded workout sessions may be displayed on the console, or another connected device, such as live studio sessions, powerlifting sessions, full-body sculpting sessions, and world-class coaching sessions. Further, the console may be configured such that a remote trainer, a live videofeed, or a pre-recorded video feed or workout can control the resistance or other parameters of the exercise machine. Also, the console may be configured with multiple user profiles to store preferences and other settings for more than one user.
In addition to the accessories disclosed above, m some embodiments the exercise machine may further include other accessories, such as dumbbells, kettlebells, a barbell holder attached to the frame or the power rack for storage of the barbell, an adjustable weight bench for performing weight lifting exercise while lying down, sitting, or somewhere in between lying down or sitting, and a rower attachment that may be connected to one of the pull cables to allow the exercise machine to be used as a rowing machine by a user.
Additionally or alternatively, any of the example components disclosed herein in connection with the exercise machine may be moved from generally mirrored left-and-right positions to other positions, such as non-mirrored positions or center positions. For example, instead of left and right pulleys, a single center pulley may be employed in some situations. In another example, more than two pulleys may function similarly to the left and right pulleys disclosed in the drawings. Therefore, the terms “left” and “right” as disclosed herein are for convenience only and are not intended to dictate generally mirrored left-and-right positions of components.
In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely example representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.
Terms used herein and especially in the appended claims (e.g., bodies of the appendedclaims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).
Additionally, if a specific number of an introduced claim recitation is intended, suchan intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may containusage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing suchintroduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least tworecitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, Band C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.
Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the summary, detailed description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”
Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first,” “second,” “third,” etc., connote a specific number of elements, these terms shouldnot be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.
The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention as claimed to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
