Referring now to
A controller 420, schematically illustrated as a circuit board in
A display panel 440 on the exterior of housing 20 is connected to controller 420. Display panel 440 is provided to display information stored in the memory of controller 420 regarding use of exercise device 10. By way of example and not limitation, display panel 440 may display the resistance applied to spool 112 and cable 114 during a routine, the number of repetitions during a specific time interval, a desired target goal of repetitions, and the current number of repetitions performed during an exercise routine. Control buttons 442 are provided on the housing to reset a counting routine or timing routine.
An internal power supply 450 is provided within housing 20. Power supply 450 is connected to controller 420 by electrical lead 452. In the embodiment shown, power supply 450 is in the form of a battery 454, shown in phantom in
In accordance with another aspect of the present invention, controller 420 is connected by an electrical lead 462 to a universal (USB) port 460 that allows information stored within the processor/memory unit of controller 420 to be transferred to an external device, such as a laptop computer.
In accordance with another aspect of the present invention, the free end of cable 114 includes a conventional connection device (not shown), such as a clevis, to facilitate attachments being connected to cable 114.

Referring now to
As shown in
Handles or hand grips 512 may be attached to the connectors on the free end of cable 114 to perform a variety of different arm and upper-body exercises. For example,
During each exercise, spool 112 rotates about post 42 in a first direction as cable 114 is drawn out of housing 20 through opening 52′ in grommet 54. As will be appreciated, rotation of spool 112 causes elongated pin 122 that is attached thereto to also rotate in the first direction. Because elongated pin 122 rotates with spool 112, the inner ends of springs 210, 220, 230 rotate with spool 112 as it moves in the first direction. Because outer end 214 of spring 210 is captured by boss 92 on second housing section 24, spring 210 always exerts a resistive force on rotations of spool 112. Depending upon the position of selector pin 252, as illustrated in phantom in
In accordance with a still further aspect of the present invention, exercise device 10 is designed to be used in conjunction with a pre-programmed exercise routine preferably set forth in memory or “online” on a computer 520, illustrated in
The present invention thus provides a variable-resistance, portable exercise device 10 that may be used by a wide variety of people in a number of different locations in conjunction with a pre-programmed workout routine stored in memory in a computer device. Exercise device 10 is suitable for use by users “U” of all ages and capabilities and, likewise, may be used by the elderly and infirmed who are limited to a wheelchair or a bed.
