Definitions

  • US Patent Number 5352169 to Eschenbach discloses an exercise apparatus that simulates walking and running. According to US Patent Number 5352169 to Eschenbach , other exercise devices have been proposed that provide particular motions while a user's feet engage a pedal platform.
  • US Patent Number 5352169 to Eschenbach notes that parallel motion pedal constraint is shown in US Patent Number 4,643,419 to Hyde where pulleys of the same size are coupled with a belt or chain to maintain a pedal platform horizontal or parallel to a base through a rotatable cycle of motion.
  • US Patent Number 5352169 to Eschenbach while parallel platforms help stabilize the balance of the user, the heel of the user's foot raises from the platform during operation when the knee is bent in the upper positions of pedal platform movement.
  • the ankle ligaments and particularly the Achilles tendon are subjected to excessive stress when the heel is raised forcing all weight on that leg to be supported by the ball of the foot.
  • US Patent Number 5352169 to Eschenbach discloses an apparatus that includes a non-parallel elongate pedal position control which, according to US Patent Number 5352169 to Eschenbach , affords the benefits of a safer stand-up exercise apparatus having low ankle/Achilles tendon stress compared to parallel platform control.
  • the apparatus disclosed in US Patent Number 5352169 to Eschenbach is intended to provide variable intensity exercise through a leg operated, cyclic motion mode of exercise in which an elongate pedal supporting each foot is guided through successive positions during the motion cycle while load resistance acts upon a crank mechanism.
  • the apparatus includes a separate elongate pedal for each foot, each partially supported by a rotary crank which normally completes one full revolution during a cycle and is phased approximately one hundred and eighty degrees relative to the crank for the other elongate pedal through a bearing journal attached to the framework.
  • the elongate pedals are not free to rotate but are supported at the other end in one embodiment by a roller element which is attached to the elongate pedal and in contact with a track attached to the frame to form a four-bar linkage known in the literature as a slider-crank mechanism where the elongate pedal is the coupler link.
  • the frame is made collapsible with the use of telescoping tubing being an integral part of the track supporting the roller element.
  • US Patent Application Publication No. US2004/0248707 A1 in the name of Rodgers describes an exercise apparatus comprising a foot member coupled to a crank system which is linked to a variable stride system configured to allow the user to vary the length of his stride during use of the apparatus, wherein the apparatus is configured such that a foot of the user can travel in a substantially curvilinear path during use of the apparatus.
  • the present invention provides a device as claimed in claim 1, that can simulate a more authentic walking motion than has heretofore been available from known walk simulating devices.
  • a device that can simulate a walking motion for each leg of a user that brings about a different level of exertion, a different range of muscle movement and involvement, and/or a different balancing effort when the leg moves forward as opposed to when the leg moves rearwardly.

  • the drive motor can be selectively disabled or can be omitted entirely and the walking motion of the user's legs can be the source of the motive power to move the user interface element or the sliders.
  • the walk trainer device can be used by persons afflicted with less severe disabilities with limited self-walking skills such as, for example, persons recovering from an accident, and persons with non-impaired walking skills desiring to exercise. It can thus be understood that the walk trainer device is configurable as a training machine on which a user would stand upright on his or her own power (i.e., a self standing person) or would be assisted to stand upright. Each one of the user's feet is supported on a movable “slider” and the pair of "sliders” are arranged to move on parallel walking paths. The pair of "sliders" is supported on a base platform that itself may have appropriate support feet that contact a floor surface and support the entire walk trainer device in a stable manner on the floor.
  • a walk trainer device 310 is provided a structure that allows a user to exercise the arms and upper torso at the same time as the user's legs and lower torso involved with the motion loop movement of the sliders.
  • the walk trainer device 310 includes two main components, a base platform 360 with two built in parallel tracks, a pair of sliders 362 supported for reciprocating movement in the parallel tracks, a support frame 364, and an upright tray assembly 366 having a rigid leg 368 with a lower end fixedly secured to the base platform 360 and an upper end supporting a horizontal tray 370 that extends over a forward portion of the travel path of the sliders 362.
  • the horizontal tray 370 is at a height generally corresponding to the average height of the mid-torso area of a user for the purpose of providing a mounting structure for a pair of stride poles 372.
  • the pair of stride poles 372 each have a lower end pivotally mounted via a pivot 374 to a respective one of the sliders 362 and has a suitable profiled hand grip at its upper hand configured for a user to grasp the stride pole.
  • Each stride pole 372 is pivotally secured to the horizontal tray 370 via a tray pivot 376. The stride poles 372 pivot relative to the horizontal tray 370 as the arms of the user swing.
  • the walk trainer device can also be provided with accessories such as, for example, a pair of spaced apart parallel hand rails that extend at an appropriate height so that the user can grip the hand rails for support and for assistance in entering onto the pair of "sliders" and exiting the pair of "sliders.”
  • accessories well known in connection with exercise devices can be provided such as a display panel for displaying elapsed walking distance, the pace or speed of walking, and other desirable activity statistics.
  • the present invention provides, in one aspect therof, a walk trainer device whereupon each of the "sliders” moves in a forward direction by virtue of a user applying a forward movement of the respective foot while the foot remains engaged with the “slider.”
  • the user's foot remains in engagement with the “slider” but the “slider” now is moved in a reverse direction via the user's leg movements and/or with the assistance of a stroke power mechanism that can be optionally provided with the walk trainer device.
  • Each "slider” is configured with a cam profile that has a specific geometric shape and is compatibly configured to cooperate with a cam follower that is pivotally connected to the base box.
  • each "slider” can be provided with a cam profile along the bottom surface of the “slider” and each one of the pair of cam follower can be pivotally connected to the base box at the general location of the middle area of the base box, as viewed lengthwise. It is therefore possible to provide each "slider” with a cam profile that causes the forward or leading edge of the "slider” to rise as the user continues the forward stroke - i.e. a simulation of a walking stroke of a person walking up a hill.
  • each "slider” simulates the experience of an uphill forward walking stroke and a flat reverse walking stroke (the reverse walking stroke simulates that portion of a natural walking gait during which the respective foot remains at rest while the other foot is performing a forward walking stroke).
