The present invention generally relates to the field of magnetically assisted resistance apparatus. Specifically, the present invention relates to a programmable magnetically assisted resistance apparatus.
Resistance apparatuses, like weight training machines, for instance, are using weights in conjunction with gravity for creating a load used as a resistance for training purposes. Each weight is going to provide a constant load. These resistance apparatuses are therefore generally equipped with a plurality of discrete weights to provide a choice of loads to accommodate various training needs.
Resistance apparatuses can also be embodied differently. For instance, industrial tensioners can also benefit from tensioning mechanisms for maintaining a desired tension in a chain drive or a belt drive.
However, these resistance apparatuses are using discrete loads that might not match properly the load requirement at a specific time. Therefore, it would be desirable to have a resistance apparatus that can offer load variations. Additionally, it would be desirable to provide a resistance apparatus that is lighter and can be retrofitted on existing equipment.
An object of the present invention, in accordance with at least one embodiment thereof, is to provide a resistance apparatus that can dynamically modify its resistance on a mechanical system.
One other object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can be preprogrammed to provide load variations for specific uses.
One object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can dynamically alter its resistance in respect with other parameters.
One other object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can deliver load variations in respect with a displacement, a time, a temperature or a number of cycles.
One object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can provide a safety feature in changing the resistance when a predetermined threshold is met.
One other object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that has a default mode when power is stopped to prevent undesirable behaviors.
One object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that is operatively connected with a database to automatically adjust its resistance in respect with previously recorded data.
Another object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can be retrofitted to prior art weights equipped machines or static tensioners.
Another object of the present invention, in accordance with at least one embodiment thereof, provides a resistance apparatus that can be embodied linearly or rotatably to provide a dynamically adjustable resistance.
Other and further objects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. Other and further aspects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
The above and other objects, features and advantages of the invention will become more readily apparent from the following description, reference being made to the accompanying drawings in which:
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the invention. Furthermore, an embodiment of the invention may incorporate only one or a plurality of the aspects of the invention disclosed herein; only one or a plurality of the features disclosed herein; or combination thereof. As such, many embodiments are implicitly disclosed herein and fall within the scope of what is regarded as the invention.
Accordingly, while the invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the invention and is made merely for the purposes of providing a full and enabling disclosure of the invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the invention in any claim of a patent issuing here from, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the invention. Accordingly, it is intended that the scope of patent protection afforded the invention is to be defined by the issued claim(s) rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
With regard solely to construction of any claim with respect to the United States, no claim element is to be interpreted under 35 U.S.C. 112(f) unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to and should apply in the interpretation of such claim element. With regard to any method claim including a condition precedent step, such method requires the condition precedent to be met and the step to be performed at least once during performance of the claimed method.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” When used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring the drawings, one or more preferred embodiments of the invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses. Hence, a novel resistance apparatus will be described herein after.
The resistance apparatus 12 may cooperate with devices such as mainframes, minicomputers, personal computers, laptops, personal digital assistants, phones, or the like, capable of connecting to the network 20. The resistance apparatuses 12, 14, 16 may transmit data over the network 20 or receive data from the network 20 via a wired, wireless, or optical connection.
The servers 18 may include one or more types of computer systems, such as a mainframe, minicomputer, or personal computer, capable of connecting to the network 20 to enable servers 18 to communicate with the resistance apparatuses 12, 14, 16. In alternative implementations, the servers 18 may include mechanisms for directly connecting to one or more resistance apparatuses 12, 14, 16. The servers 18 may transmit data over the network 20 or receive data from the network 20 via a wired, wireless, or optical connection.
In an implementation, consistent with the present invention illustratively embodied herein, the servers 18 may include a search engine 22 usable by the resistance apparatuses 12, 14, 16. The servers 18 may store data, such as past usage records, accessible by the resistance apparatuses 12, 14, 16.
With reference to
The following discussion provides a brief, general description of an exemplary computer system in which at least some aspects of the present invention may be implemented. The present invention will be described in the general context of computer-executable instructions, such as program modules 172 being executed by a computerized device. However, methods of the present invention may be affected by other apparatuses. Program modules may include routines, programs, objects, components, data structures, applets, WEB 2.0 type of evolved networked centered applications, etc. that perform a task(s) or implement particular abstract data types. Moreover, those skilled in the art will appreciate that at least some aspects of the present invention may be implemented with other configurations, including hand-held devices, multiprocessor system, microprocessor-based or programmable consumer electronics, network computers, minicomputers, set top boxes, mainframe computers, gaming consoles and the like. At least some aspects of the present invention may also be carried out in distributed computing environments where tasks are performed by remote processing devices linked through a communications network as exemplified in
With reference to
A number of program modules 172 may be stored on the hard disk 127, magnetic disk 129, (magneto) optical disk 131, ROM 124 or RAM 125, such as an operating system 135 (for example, Windows® NT® 4.0, Android, sold by Microsoft® Corporation of Redmond, Wash. or Mac OS, iOS sold by Apple Inc.), one or more application programs 136, other program modules 137 (such as Alice™, which is a research system developed by the User Interface Group at Carnegie Mellon University available at www.Alice.org, OpenGL® from Silicon Graphics Inc. of Mountain View Calif., or Direct 3D from Microsoft Corp. of Bellevue Wash.), and/or program data 138 for example.
A user may enter commands and data into the computer 120 through input devices, such as a keyboard 140, a camera 141 and a pointing device 142. Other input devices (not shown) such as a microphone, joystick, game pad, satellite dish, scanner, a touch sensitive screen, accelerometers or a motion-sensor detector such as KINECT™ that are adapted to sense movements of the user or movements of a device, or the like, may also be included. These and other input devices are often connected to the processing unit 121 through a serial port interface 146 coupled to the system bus 123. However, input devices may be connected by other interfaces, such as a parallel port, a game port, blue tooth connection or a universal serial bus (USB). For example, since the bandwidth of the camera 141 may be too great for the serial port, the video camera 141 may be coupled with the system bus 123 via a video capture card (not shown). The video monitor 147 or other type of display device 150 may also be connected to the system bus 123 via an interface, such as a video adapter 148 for example. The video adapter 148 may include a graphics accelerator. One or more speakers 162 may be connected to the system bus 123 via a sound card 161 (e.g., a wave table synthesizer such as product number AWE64 Gold Card from Creative® Labs of Milpitas, Calif.). In addition to the monitor 147 and speaker(s) 162, the computer 120 may include other peripheral output devices (not shown), such as a printer, a hi-definition television and a scanner for example. As an alternative or an addition to the video monitor 147, a stereo video output device, such as a head mounted display or LCD shutter glasses for example, could be used.
The computer 120 may operate in a networked environment defining logical connections to one or more remote computers 120, such as a remote computer 149. The remote computer 149 may be another computer 120, a server 18, a router, a network PC, a peer device or other common network node, and may include many or all of the elements described above relative to the computer 120. The logical connections depicted in
When used in a LAN, the computer 120 may be connected to the LAN 151 through a network interface adapter (or “NIC”) 153. When used in a WAN, such as the Internet, the computer 120 may include a modem 154 or other means for establishing communications over the wide area network 152 (e.g. W-Fi, WnMax). The modem 154, which may be internal or external, may be connected to the system bus 123 via the serial port interface 146 or another type of port interface. In a networked environment, at least some of the program modules depicted relative to the computer 120 may be stored in the remote memory storage device 166. The network connections shown are exemplary and other means of establishing a communication link between the computers 120 may be used through a host adaptor 155 coupled by a SCSI bus 156, for instance. The exemplary network and the exemplary computer system described above are adapted to carry on the following embodiments:
A magnetic resistance apparatus 170, hereinafter referred to MRA 170, is embodied as a weight training machine 174 and is illustrated in
The set of cassettes 206 includes a plurality of individual cassettes 210 and the number of assembled cassettes 210 is defined by the resistance amount required by the exemplary weight training machine 174 or the intended alternate use of the MRA 170. Coupling the cassettes 206 in set of six cassettes 210 is bringing some benefits that are going to be explained in more details below. The embodiment illustrated in
electromagnets 252 assembled in the six cassettes 210 sub-assembly, which means twelve electromagnets 252 are connected to power output of the drives in order to interface and variably manage the electromagnets 252 in respect with a translation position along the pair of rails. Each sub-assembly of six cassettes 206 has a thickness corresponding to a length of two magnets 290 assembled in the pair of vertical rails 198. The PC board 226 is hence configured to dynamically manage the electromagnets 252 in relation with a displacement thereof along a length of two magnets 290 representing a complete 720-degree electrical cycle. A cassettes 210 sub-assembly is made by sets of six cassettes 210 to offer a simple modularity that can be multiplied to meet the resistance requirement of the MRA 170; each cassette 210 sub-assembly being effective over a complete 720-degree electrical cycle with three poles and their respective two polarities thereof. A center portion of the set of cassettes 206 is enclosed by a cover 230 giving access to the internal structure of the set of cassettes 206. A data connector 234 adapted to transmit data of a load cell 280 and a power connector 236 adapted to transmit power to actuate the electromagnets 252. Data and power are communicating over distinct circuits and connectors 234, 236 to prevent any induced interferences in the communicated signals.
Each cassette 210 is including a body 240 and an aluminum frame 244 as best seen in
Moving now to
It may be appreciated that the MRA 170 may be configured to be retrofitted onto a conventional weight training machine 174 thereby replacing the steel plates 194 or other weight system and typically vertical rails 198. In a preferred embodiment, the MRA 170 offers a plug and play solution allowing for its installment onto a conventional weight training machine 174 without additional reconfiguration or adjustment. To that end, the installation of the MRA 170 may simply comprise the replacement of the superposed steel plates 194 with the superposed electromechanical plates 206 and pre-existing vertical rails with the vertical rails 198 comprising the magnets 290. In this example, the installation of the MRA 170 may comprise, in a first step, removal of the pair of pre-existing vertical rails and steel plates 194. In a second step, the electromechanical plates 206 may be assembled on the pair of vertical rails 198. The vertical rails 198 may be affixed to the upper portion 186 and lower support 190 by means of optional upper and lower adapting plates 218, 222. Different upper and lower adapting plates 218, 222 are available and adapted to mate with the upper portion 186 and lower support 190 of differing conventional weight training machines 174. The vertical rails 198 may further be adapted to be affixed to the upper and lower adapting plates 218, 222 by any suitable fastening means such as, but not limited to, bolts, buckles, latches, clips, grommets, or pins. In a third step, the length of the cable 202 may be adjusted to accommodate the MRA 170, when necessary.
It may be appreciated that the MRA 170 may therefore be utilized to modify a convention weight training machine 170 thereby adding a lighter resistance apparatus which can offer resistance variations.
Referring now to
The electromagnetic behavior of the MRA 170 is described in more details in reference with
In certain embodiments, the MRA 170 comprises an encoder 180 configured to detect the movement displacement of the electromagnetic cassettes 206. The encoder 180 may comprise suitable electro-mechanical system configured to convert motion to an output signal 182, such as a rotary encoder. Moreover, the encoder 180 may be an absolute or incremental encoder. Similarly, the encoder 180 may be a mechanical, optical, on-axis magnetic or off-axis magnetic. The output signal 182 may be transmitted to a storage media of the computer 120. The encoder 180 may be located at any suitable location on the MRA 170. For example, the encoder 180 may be located above or below the electromagnetic cassettes 206, the upper portion 186 or the lower support 190. In certain embodiments, the encoder 180 may be connected to the cable 202, to the upper deck 218, to the lower deck 222, to an individual cassette 210 or to any other suitable component of the MRA 170.
Referring now to
In further embodiments, the computer 120 may store the data 185 on a storage device, such as the hard disk 127 or the storage device 166, By storing the data 185 for a particular user, the computer 120 may further derive additional analytics regarding the evolution of a user's performance over time. To that end, baselines or trendlines derived by the computer 120 may assist the user, sporting professionals such as trainers or medical practitioners by supplying them with empirical data to identify changes in performance. For example, performance above a predetermined boundary of the user's performance trend line may indicate a positive progression of a user's performance and training effectiveness. Similarly, performance significantly above a predetermined boundary of the user's performance trend line may indicate a rapid progression due to performance enhancing drugs. Inversely, performance under a predetermined boundary of the user's performance trend line may indicate an ineffective routine, an underlying affliction or an undisclosed injury.
In yet another embodiment, performance analytics generated by multiple MRAs 170 may be compiled and stored on a central computer 120 accessible by a trainer or coach. Configured in this manner, the performance of multiple users may be analyzed to derive additional comparative performance analytics. In other embodiments, the MRA 170 may be configured to distinguish between multiple users thereby associating performance data to a specific user.
The following figures are to be considered in the context of a possible embodiment of the invention. Referring now to
