Aspects of the present invention involve exercise equipment, and more particularly involve exercise equipment, such as a treadmill, with a four wheel combination elevation and transport assembly, a dual power plug arrangement, an arm support upright assembly providing structural and aesthetic flexibility, and a diagnostic light arrangement, alone or in combinations.
The health benefits of regular exercise are well known. Many different types of exercise equipment have been developed over time to facilitate exercise as well as medical rehabilitation. One example of a successful type of exercise equipment is the treadmill. Conventionally, a treadmill provides a moving surface, typically a belt arranged between rollers, that moves at a specified rate. The user walks or runs on the moving surface. Besides having well developed moving surface mechanics to provide a great user experience, it is important to also present a treadmill that is aesthetically pleasing, easy to move about a home, health club, rehabilitation facility or the like, and able to be arranged in a home or other area as a user desires.
Conventional treadmills typically include a pair of front wheels that allow a user to pick up the back of the treadmill and roll the treadmill to a desired location. Treadmills that incorporate only the pair of front wheels force the user to support a substantial amount of the weight of the treadmill making movement of the treadmill strenuous. Therefore, there is a need in the art for a treadmill that allows for efficient and reliable movement of the treadmill.
To drive the tread belt or other moving surface, typical conventional treadmills include a motor and drive electronics. Most conventional treadmills also include other electronics, such as to provide a customized workout or for selecting from existing preprogrammed workout routines. Conventional treadmills typically provide one power outlet where a power cord is connected and may be plugged into a conventional wall outlet. The power outlet is typically provided at the front or rear of the treadmill. Many spaces are not tailored for placement of a treadmill, and wall plugs are inconveniently located in relation to the desired placement of a treadmill. In these situations, it is often necessary to add extension cords in order to reach a wall outlet. Oftentimes, the treadmill power outlet will be on a side of the treadmill away from the desired outlet; thus, causing the cord to be stretched around the treadmill to reach the outlet. Therefore, there is a need in the art to provide for alternative or additional power outlets on the treadmill to provide for alternative power cord location.
As with any electromechanical equipment, exercise equipment, whether a treadmill or other form of exercise equipment, requires periodic maintenance and sometimes malfunctions. In an effort to remind users of maintenance and expedite diagnosis of malfunctions, diagnostic light arrangements have been developed. The lights are illuminated in various combinations to identify various issues. However, conventional treadmills typically arrange the lights adjacent or on the various internal electronics, which are placed under covers. As such, the cover must be removed to view the lights. Therefore, there is a need in the art to provide for diagnostic lights that viewable without removal of covers or otherwise easily viewed by a user.
Various aspects of the present invention discussed in detail below address these and other concerns with conventional treadmills.
One aspect of the invention involves an exercise apparatus, such as a treadmill, elliptical, exercise bicycle, etc., where the exercise apparatus includes a frame with at least one first wheel operably coupled with the frame. An elevation support frame defines a first portion and a second portion where the first portion is pivotally supported on the frame and the second portion operably supports at least one second wheel. A motor is coupled with the elevation support frame and the motor is adapted to pivot the elevation support frame and extend the at least one second wheel away from the frame. As such, the elevation support may lift the front of the exercise device to provide some degree of grade to the exercise apparatus. Further, the elevation support may extend from the frame to provide a wheeled arrangement for transporting the exercise device.
Another aspect of the invention involves an exercise apparatus, such as a treadmill, elliptical, exercise bicycle, stair stepper, etc., the exercise apparatus includes a frame supporting an exercise device having at least one motor and associated motor control electronics. At least one console defines user inputs in communication with the control electronics. A shroud assembly is coupled with the frame and the shroud assembly covers at least the at least one motor. At least one status light is supported on the shroud and visible from a position external the exercise device. The at least one status light is adapted to receive illumination signals from at least one of the control board, the at least one motor and/or the console. The diagnostic lights are not necessarily supported on the panel, but may be arranged on some other portion of the exercise apparatus so that they are visible without having to remove the shroud. It is also possible to arrange the diagnostic lights in such a manner that they are only visible from some angles. For example, the diagnostic lights might be mounted on a panel located under below a shroud, but visible from the side of the device as they are arranged below a lower edge of the shroud.
Another aspect of the invention involves an exercise apparatus, such as a treadmill, elliptical, exercise bicycle, stair stepper, etc., the exercise apparatus includes a frame defining a first region and a second region. The exercise apparatus further includes at least one power plug selection switch operably supported on the frame. A first power plug is operably supported on the first region of the frame where the first power plug is in electrical communication with the at least one power plug selection switch. A second power plug is operably supported on the second region of the frame where the second power is plug in electrical communication with the at least one power plug selection switch.
Another aspect of the invention involves an exercise apparatus, such as a treadmill, elliptical, exercise bicycle, stair stepper, etc., the exercise apparatus includes a frame with at least one upright coupled with the frame. The at least one upright supports an arm member. The at least one upright includes an inner upright frame member coupled with the frame, the inner upright frame member defining a first side and a second side. Further, the at least one upright includes a first outer shroud member adapted to shroud the first side of the inner upright frame member, and a second outer shroud member adapted to shroud the second side of the inner upright and further adapted to engage the first outer shroud member.
The detailed description will refer to the following drawings, wherein like numerals refer to like elements, and wherein:
The present application discusses various novel and inventive aspects of a treadmill. Particularly, the present application describes and illustrates a treadmill having a four wheel combination elevation and transport assembly that functions to both elevate the front of the treadmill to provide different angular orientations of the treadmill surface and also functions to provide a mechanism for efficient movement of the treadmill about a home, health club, etc. Further, the present application describes and illustrates a treadmill having a multiple power plug arrangement that functions to allow power to be supplied to the treadmill electronics from a plurality of different plug locations thereby allowing the treadmill to be most efficiently placed in a particular location while also allowing the power cord to be located and routed in a discrete manner. Still further, the present application describes and illustrates a treadmill having a novel upright configuration that combines high strength steel with molded plastic in a manner that allows aesthetically pleasing designs as well as optimizing treadmill weight considerations without sacrificing strength. Finally, the present application describes and illustrates a treadmill having a diagnostic light arrangement located on the outside or surface of a decorative cover that allows easy viewing of diagnostic codes (via light illumination) without having to disassemble the treadmill. The various aspects of the invention discussed herein are all shown implemented in a single embodiment of a treadmill. Each of the various aspects of the inventions and the associated embodiments discussed herein, however, may be implemented alone or in combination on any existing or future treadmill configuration. Further, all of the various aspects of the inventions and associated embodiments discussed herein may be implemented in other types of exercise equipment.
A. Treadmill
Referring variously to
A rear roller assembly 204 and a front roller assembly 706 are also supported between the left frame rail 104 and the right frame rail 102, slightly rearward and forward the respective ends of the tread deck 202. The rear roller assembly 204 includes a rear roller 210 and the front roller assembly 706 includes a front roller 710, both rotatably supporting a tread belt 106 therebetween. The tread belt 106 moves over the tread deck 202 and provides the walking or running surface for a user on the treadmill 100.
The back frame rail 712 of treadmill 100 has a left support 712 and a right support 130 attached to it which extend from the back frame rail 712. The treadmill 100 also includes an elevation and transport assembly 132 comprising a left rear wheel 502, a right rear wheel 306, a left front wheel 122 and a right front wheel 120. The elevation and transport assembly 132 is discussed in more detail below. More particular arrangement, the left support 712, right support 130, left rear wheel 502, and right rear wheel 306 are substantially in contact with the ground when the treadmill 100 is in use. The front wheels may be in contact in the lowermost post position, or may be arranged to only contact the ground when the treadmill is pivoted into a moving orientation as discussed below.
For upper body support, a left handrail 114 and a right handrail 112 are supported at the top of a left upright 110 and a right upright 108 respectively. At the front of the handrails 114, 112 a display 212 and console 118 are supported. As is known in the art, the display 212 may include such information as heart rate, miles walked, exercise programs, and other information. Also supported between the handrails 114, 112 is an arcuate bar 116, just rearward the console 118. The arcuate bar 116 supports a control console 124, a left grip heart rate electrode 126, and a right grip heart rate electrode 128. The electrodes 126, 128 detect the heart beat of a user gripping the electrodes. The heart beat signals are sent to a processor (not visible) in the console 118 unit in order to display the user's heart rate. The control console 124 includes various input mechanisms to change the elevation of the treadmill, i.e., the grade of the walking surface, and to also change the tread belt rotation speed.
At the front of the treadmill 100, a tread drive motor 206 is transversely mounted between the left and right frame rails 104, 102. The tread drive motor 206 includes an axle 214 supporting a pulley 216 adapted to engage a belt (not shown) to drive the front roller 710. Also, at the front of the treadmill 100 is the combination elevation and transport assembly 132, an associated elevation motor 208 and a control board 218 which are discussed in more detail below. As best shown in
B. Elevation and Transport Assembly
Referring to
The rear wheels 502 and 306 are pivotally supported at the rear end of associated wheel support brackets 802 and 302 respectively. As best shown in
In some conventional exercise equipment, only the front two wheels 120, 122 are provided. If the transport assembly 132 is withdrawn, the user may still move the treadmill 100 by only engaging the front two wheels 120, 122, as in conventional treadmills. With the transport assembly 132 extended, the transport assembly 132 bears the weight of the treadmill 100, rather than the user. Preferably, the transport assembly 132 is arranged so that the center of gravity of the treadmill 100, in the elevated position, is roughly centered above the assembly 132 between the front 120, 122 and rear wheels 306, 502. In this way, the transport assembly 132 bears most of the weight in the transport position (after the user has lifted the treadmill 100 to engage the four wheels 306, 502, 120, 122).
The rear wheels 306, 502 are pivoted downwardly through a pivot bracket 808 connected with a deck elevation motor 208. The pivot bracket 808 is generally triangular shaped with one point of the triangular shape being fixed to the front pivot rod 902. A second rearward point on the triangle defines a concave recess adapted to engage the brace 1004 extending between the wheel support brackets 302, 802. The pivot bracket 808 is not fixed to the rear brace 1004 but rather merely touches the rear brace 1004 so that when the assembly 132 is rotated downwardly, rotational movement with respect to the pivot bracket 808 may occur unimpeded. It is possible to lubricate the interface between the pivot bracket 808 and the brace 1004, through liquid lubricants or structural interfaces that reduce the coefficient of friction.
The top point on the triangular pivot support bracket 808 pivotally supports a screw collar 906. The deck elevation motor 208 is arranged to drive a motor screw 910. The motor screw 910 extends through the screw collar 906. As is known in the art, the motor screw 910 defines threads adapted to engage the threads within the screw collar 906. Thus, by rotation of the motor screw 910, the screw collar 906 is driven forwardly or rearwardly depending on the rotation direction of the screw 910. Driving the screw 910 rearwardly causes the pivot bracket 808 to rotate downwardly about the front pivot, rotating downwardly in such a manner presses down on the transverse brace 1004 which in turn causes the rear wheels 306, 502 to move downwardly from the rear to elevate the front of the treadmill 100. In contrast, when the screw 910 is rotated in the opposite direction the screw collar 906 is pulled forwardly allowing the deck to settle back down into its flat position. To facilitate such movement, the screw collar 906 is pivotally supported on the pivot bracket 808 and the motor drive screw 910 is also pivotally supported. Such pivotal support is necessary because the angle and elevation of the screw collar 906 changes as the pivot bracket 808 rotates downward or upward about the front pivot rod 902.
Besides four wheels, it is possible to use rollers, one front wheel and two rear, or two front and one rear, or other combinations. Further, it is possible to rotatably support the front wheels 120, 122 or rear wheels 306, 502 to ease turning the treadmill 100 when it is being moved.
C. Upright
The right inner member 1204 generally defines an elongate upstanding three sided piece. The right inner member 1204 (and upright generally) extends upwardly from the right frame rail 102. The right inner member 1204 has a side wall 1502, a forward wall 1206 and a rearward wall 1208, but does not define a second side wall. As such, as best shown in

D. Power Plugs and Associated Electronics
The location of the plugs 508 and 704 and switch 506 is selected to facilitate the front of the treadmill 100 to be arranged generally facing a power supply, i.e., with the front of the treadmill 100 facing an AC power source, or with the rear of the treadmill 100 facing the power source. In a frontward facing orientation, the front plug 508 would be used and the associated power cord may be discreetly located between the front of the machine and the AC power source. In contrast, if the rear of the machine is arranged to face the AC power source, the power cord may be discreetly arranged and utilize the rear plug 704. Without such a dual plug arrangement, to reorient the device would require in one orientation or the other the cord to be serpentinely routed along the entire length of the treadmill 100 to get to the power source. Stated another way, without a front plug 508, but in a situation where the user would like to orient the front of the treadmill 100 to face the power supply, a cord would have to be routed between the rear plug 704 along the length of the treadmill 100 to the front of the treadmill 100 and to the AC power source. With such power cord arrangements, which is typical in prior art treadmills, the cord oftentimes is in the way of the user. Further, a much longer cord must be supplied with the treadmill or extension cords used to provide access to the power plug in any particular arrangement.
Regardless of the switching configuration, when either plug 508, 704 is activated power is supplied through a conventional circuit breaker 2102 and a line filter 2104 to the control board 218 of the treadmill 100. The control board 218 comprises an elevation control board and a motor control board and includes a communication and power path to the treadmill deck elevation motor 208 and the treadmill belt drive motor 206. The control board 218 also includes a communication path to the console 118 and control inputs 124. Finally, the control board 218 includes a CE Harmonics filter 2106 arrangement. Conventional control signals for the treadmill deck elevation motor 208 and the treadmill belt motor 206 are supplied through the console 118 or control inputs 124. As such, a user may adjust the treadmill deck elevation and the treadmill belt speed and also turn the treadmill 100 “on” through various switches and inputs on the console 118 or control inputs 124 to the control board 218. Embodiments of the present invention may include more than two plugs and as such may include a plurality of plugs and the appropriate switching arrangement to select the various plugs. The power inlets may be 15 or 20 amp rated and conforming to IEC320 specifications, in embodiments conforming to the present invention. Besides manually activated switches, it is also possible to use a relay or other switching mechanism in embodiments of the present invention.
E. Diagnostic Lights
Conventionally, diagnostic lights are not visible outside the treadmill decorative housing, or any exercise device shrouding. As such, when a treadmill is functioning or malfunctioning as the case may be, it is necessary to remove some portion of the shrouding in order to view the diagnostic lights. Note, the covers while being partially decorative in nature are also functional by providing protection for the underlying components and performing other functions as well.
Generally speaking, various combinations of the diagnostic lights 134-1, 134-2 to 134-R convey to a knowledgeable viewer status information of the motor control subsystem and other electronic subsystems of the treadmill 100. In a simple arrangement, each diagnostic light 134-1, 134-2 to 134-R is associated with one diagnostic status. In a more complicated or sophisticated arrangement, the lights 134-1, 134-2 to 134-R may be lit in various combinations to display a greater amount of diagnostic and general status information. Further, multi-color lights may be used where various light combination indicate status. For example, a red and green light emitting diode may be employed, where red indicates a malfunction and green indicates proper function.
In one particular implementation, one of the diagnostic lights 134-1, 134-2 to 134-R is associated with a grade up status indicator, one of the diagnostic lights 134-1, 134-2 to 134-R is associated with a grade down status indicator, one of the diagnostic lights 134-1, 134-2 to 134-R is associated with a speed movement status indicator, one of the diagnostic lights 134-1, 134-2 to 134-R is associated with a speed control pulse width modulator status indicator, and one of the diagnostic lights 134-1, 134-2 to 134-R is associated with a belt enable indicator. The grade up status indicator is driven from the command relay that engages grade up motor windings in the elevation motor 208. Generally speaking, the grade up status light illuminates when the control board 218 sends a signal to the elevation motor 208 to move upward. As such, if the grade up indicator does not illuminate, then the control board 218 is not sending the commanded voltage to the elevation motor 208.
Similar to the grade up diagnostic light, the grade down diagnostic light is illuminated when the control board 218 sends a signal from the command relay that engages the grade down motor windings of the elevation motor 208. Thus, if the elevation motor 208 is receiving the grade down command then the grade down diagnostic light will illuminate. Conversely, if the control board 218 is sending the signal, but it is not being received, then the grade down diagnostic light will not illuminate.
The speed movement status light is set to flash with every turn of the front roller 710 showing that front roller movement sensor (not shown) is functioning correctly. Note, front roller movement sensors are well known in the art of treadmill control. If the speed movement LED does not flash then various problems might be indicated, such as the roller is not moving, the connection between the front roller sensor and the diagnostic light is broken, or a sensor or positioning problem, amongst others.
The speed control diagnostic light's intensity is directly related to speed, the faster the tread belt 106 is commanded to go, the brighter the LED's output. For example, if there is no intensity increase when an increase in speed request is sent, it might indicate that the motor control simply is not receiving the speed control signal. This is not the actual motor drive control signal, but the console (118 or 124?) generated target speed value.
The belt enable diagnostic light is illuminated as a function of whether power is being transferred to the belt drive circuitry. If the belt enable diagnostic light is illuminated, this indicates that the motor control assembly has received the belt start command and is attempting to apply power to the switching control circuitry.
It is also possible to illuminate the diagnostic/status lights as a function of the communication path between the control inputs 118 and the corresponding motor control boards located in the upper and lower portions of the treadmill 100, respectively. It is also possible to illuminate the diagnostic lights as a function of deck wear replacement status, lubrication schedules, service intervals, etc. Such diagnostic light illuminations may be done throughout operation of the treadmill 100 or at any time there is power to the treadmill 100. For example, certain diagnostic status indicators may be illuminated only at startup or shutdown of the treadmill 100 whereas other diagnostic illuminations may be continued throughout use of the treadmill 100.
