Multi-Directional Exercise Platform
A multi-directional exercise platform includes a frame, a lateral belt drive assembly, a lateral belt assembly circulation track supported by the frame, and a lateral belt assembly movably secured to the lateral belt assembly circulation track. At least one sensor is configured to obtain direction and velocity data. The lateral belt drive assembly includes a plurality of lateral belt units. The lateral belt drive assembly is configured to cause rotation of the lateral belt assembly around the lateral belt assembly circulation track according to the direction data obtained by the sensor. A processor, memory, and program instructions may be in data communication with the sensor for determining an operator's position and, subsequently, causing movement of the lateral belt drive assembly and lateral belt assembly.
This invention relates generally to exercise equipment and, more particularly, to a multi-directional exercise platform that allows a person to walk in any direction while the platform maintains the person generally in a center position. In other words, a user may walk on the platform in the manner of a treadmill with sensors determining a direction of movement and actuating respective belt assemblies as necessary to generally maintain the user's position on the platform.
A treadmill is a common exercise device has a movable track that moves continuously as a person walks in a forward direction on the track. In other words, a treadmill is essentially a conveyor belt moving toward the person walking thereon. The track is movable in this singular direction and the user must conform to walking in a linear manner toward the oncoming track. The user is confined to walking a straight line and is prevented from moving in selected non-linear directions as he would if walking naturally outdoors in an open area (e.g. a park) or on a running track. In addition, the speed of a treadmill is typically manually adjusted rather than automatically adjusted based on the speed of a user.
Various devices have been proposed in the art for treadmills that provide omni-directional functionalities, such as CA 2263592. The '592 patent includes a control means physically or electronically connected to a user that is configured to determine the user's position and orientation. Although assumably effective for its intended purpose, the '592 patent does not allow complete freedom to walk and move in any direction unimpeded by connection to a control means and does not determine a velocity of movement in the direction of movement.
Therefore, it would be desirable to have a multi-directional exercise platform that allows a person to walk in any direction while the platform maintains the person generally in a center position. Further, it would be desirable to have a multi-directional exercise platform that includes a drive roller gear motor and assemblies to rotate individual belt units around a track when a user is walking in a direction parallel to the track and that rotates the belt units laterally across the track when a user is walking in a direction perpendicular to the track and that operates the belt units both around and across the track when the user is oriented partially parallel and partially perpendicular relative to the track. In addition, it would be desirable to have a multi-directional exercise platform that includes at least one sensor for determining the position and velocity of a user on the track.

With reference to
The drive wheel 1248 may be located between arms 1247a, 1247b of the housing 1247 via a pin that extends through a hole in the center of the drive wheel 1248 and is secured at each end to the arms 1247a, 1247b so that the drive wheel 1248 can freely rotate on the pin. The gears 1248 inside the housing 1247 work in conjunction with a drive roller gear motor 1210a to turn the drive wheel 1248 as discussed below. The drive wheel 1248 may be a compressible urethane wheel that drives the lateral belt 1410 via friction. However, other materials may be acceptable.
The lateral drive belt assembly 1200 may be comprised of a plurality of drive roller units 1240, and it may be such that a drive roller unit 1240 is provided for each individual lateral belt section 1410 that is secured along the top of the circulation track 1300.
The drive roller chain 1220 (shown in
As has already been described and is discussed in more detail below, as the sensors 1500 may be configured to determine a change in the position and velocity of an operator. The sensors 1500 may be communication with the drive roller gear motor 1210a and the drive roller position gear motor 1210b. As the sensors 1500 sense a change in the direction and/or velocity of an operator, the drive position gear motor 1210b may cause the drive roller units position shaft 1230 to rotate thus causing a shift in the position of the drive wheels 1248. Movement of the operator as sensed by the sensors 1500 may further cause the drive roller gear motor 1210a to operate the drive roller chain 1220 thus causing rotation of the drive wheels 1248. Operation of the drive roller assembly 1240 in conjunction with the sensors 1500 is described in detail below with respect to
The lateral belt assembly circulation track 1300 may be a generally ovular track for guiding the lateral belt assembly 1400 around the lateral belt drive assembly 1200. The track may be secured to track stabilizers 1130 at the top and bottom to prevent the track from shifting as the lateral belt assembly travels along the track 1300. The track 1300 may be equipped with grooves for receiving the track rollers 1450 of each lateral belt section 1410.
With reference to
The belt 1420 may be stretched around a top side of the platform 1415 and the belt rollers 1430, and through the center drive, as shown in
The lateral belt link cable clamp 1450 may be secured to an underside of the platform 1415 at a position generally corresponding to the lateral belt assembly circulation track 1300. Track rollers 1460 may be secured to one side of the clamp 1440 via a pin inserted through the center of the roller and secured to the clamp such that the roller 1450 can freely rotate without falling off the end of the pin. Multiple clamps 1440 and rollers 1450 may be provided per belt section 1410 as may be required by the size of the exercise platform 1000. The rollers 1450 may be configured to fit within the grooves defined in the circulation track 1300 such that the belt section 1410 can travel along the entirety of the track 1300 without falling off.
The belt sections 1410 may be linked together via a cable 1470 (
The output device 3014 may be any appropriate device, whether now existing or later developed, for presenting data from the processor 3008. In this case, the output device 3014 may be the motors 1210. The communication device 3006 may be any device, whether now known or later developed, that allows the system 3000 to communicate with the network 3002. For example, the communication device 3006 may be a switch, wireless router, wired modem, et cetera. The network 3002 may be the World Wide Web, a private or local network, or a cellular network, for example.
The interface unit 3004 may be, for example, a computer or smart phone associated with a monitoring system that controls power to the motors 1210. Alternately, the interface unit 3004 may be contained as a part of the motor 1210.
The sensors 1500, as described above, may be located on the vertical support members 1110 of the frame 1100. The sensors 1500 may include a transmitter 3018, a processor 3020, and non-transitory memory 3022 having programming 3024. Optionally, the processor 3020, memory 3022, and programming 3024 may be separate from the sensor 1500.
Operation of the invention may be further understood by means of an example. In use, an operator stands on the platform 1000 and begins to move in whatever direction he wishes. The sensors 1500 determine the direction and velocity of the operator's movements and may communicate this information over the network to the interface unit 3004, which may be contained within the motors 1210 as described above. Based on the information received, the processor causes the one or both of the motors 1210 to begin to turn.
If the sensors 1500 determined that the operator is moving in a direction parallel to the track 1300, the drive roller gear motor 1210a is engaged. The motor 1210a turns the chain 1220, which is attached to the sprockets 1243 as described above. The rotation of the sprockets 1243 causes the wheel drive shaft 1245 to rotate, which turns the gears 1249, resulting in rotation of the wheels 1248. The rotation of the wheels 1248 causes the individual belt units 1410 to rotate around the track 1300. In this scenario, the drive roller position gear motor 1210b is disengaged, because the drive wheels 1248 are positioned parallel to the track 1300. This is illustrated in
If the sensors 1500 determine that the operator is moving perpendicular to the track 1300 (or movement of the operator has changed so that the operator is moving perpendicular to the track), the movement of the operator engages the belt 1420, causing the belt 1420 to rotate around the belt rollers 1460. In this scenario, operation of the drive roller gear motor 1210a and the drive roller position gear motor 1210b is unnecessary because the movement of the belt 140 around the belt rollers 1460 is sufficient to keep the operator centered on the platform 1000.
Finally, if the sensors 1500 determine that the operator is moving at an angle, the sensors 1500 determine the exact angle of movement, which is communicated to the drive roller gear motor 1210a and the drive roller position gear motor 1210b. The drive roller position gear motor 1210b engages the shaft 1230 thus rotating the worm 1242a. This turns the worm gear 1242b, which turns the wheel position bushing 1244, thus rotating the position of the drive wheel 1248. The motor 1210b rotates the shaft 1230 in an exact amount necessary to position the wheel 1248 at an angle equal to the direction in which the operator is moving. Three different positions of the wheel 1248 are illustrated in
At the same time, the sensors 1500 communicate to the drive roller gear motor 1210a causing rotation of the wheel 1248, thus causing the lateral belt assembly 1400 to rotate around the track 1300 as described above. Still at the same time, the belt 1420 rotates around the rollers 1420. Therefore, movement in all three directions maintains the operator in a central position atop the platform 1000.
