Description

    RELATED APPLICATIONS
  • [0001]
    This application claims priority to U.S. Provisional Application No. 60/752,304, filed Dec. 20, 2005 entitled “Automated Mechanism For Collapsing Exercise Equipment,” which is incorporated herein by reference.
  • FIELD OF INVENTION
  • [0002]
    Various embodiments of this invention relate to mechanisms for collapsing exercise equipment; specifically, to mechanisms for collapsing exercise equipment that utilize an automated electromechanical mechanism to process an input signal in order to collapse the equipment for easy and convenient storage, moving, or handling.
  • BACKGROUND
  • [0003]
    One of the many challenges facing designers of home exercise equipment is designing equipment that can easily be collapsed for quick and easy storage in a closet, under a bed, or other similar place. As exercise equipment is often large and unsightly, quick and easy storage of the equipment is an important concern for consumers. Meanwhile, the equipment must remain rugged and durable for an exercise routine and, yet, it is desirable that the same equipment be collapsible such that it can be stored with a minimum of effort and taking up a minimum of floor space.
  • [0004]
    Several exercise devices have been developed that allow a person, once he or she has completed his or her exercise routine, to collapse the equipment such that it may be easily moved or stored. These devices typically involve a series of hinges, levers, and locking pins that are manipulated by the user before and after storage. These devices, however, can be cumbersome to handle and may require additional strain and effort on the part of the user in order to collapse the equipment.
  • [0005]
    A number of devices have been developed that ease the collapsing process by utilizing a motor and mechanical mechanism. U.S. Pat. Nos. 6,077,200, 6,267,710, 6,471,622, 6,726,602, 6,872,169, and 6,913,563, for example, disclose treadmill type exercise equipment that utilize the treadmill's motor mechanism to collapse the treadmill into a flat position for easy storage. Thus, a person can more easily store the equipment while expending a minimum of additional effort because the treadmill motor performs the mechanical work needed to collapse the equipment. Such mechanized collapsing equipment, however, has not been applied to several other types of motorized exercise equipment.
  • [0006]
    Therefore, there remains in the art a long felt need for a mechanism for quickly and easily collapsing a number of types of exercise equipment while requiring a minimum amount of effort expended.
  • SUMMARY OF THE INVENTION
  • [0007]
    Various embodiments of the invention are directed toward overcoming the above shortcomings by disclosing a mechanism that may be adapted to a number of types of exercise equipment to facilitate the equipment's quick and easy automated collapse.
  • [0008]
    The device operates, generally speaking, by utilizing an electromechanical mechanism to manipulate parts of the equipment. Upon receiving an input signal, a command processor and automated control mechanism provides a signal to the equipment's electromechanical mechanism to manipulate and collapse certain aspects of the equipment, thus allowing easier storage. The device is an improvement on apparatus such as that disclosed in U.S. Pat. No. 6,786,847 wherein the mechanism is used to adjust workout parameters because, in this invention, the mechanism is also used as an automated means of collapsing the device.
  • [0009]
    This invention may operate by employing the mechanical mechanisms existing within the exercise equipment to perform the collapsing function or, alternatively, use a separate mechanical mechanism that is solely dedicated to the automated collapsing process.
  • [0010]
    Also, as claimed below, a myriad of types of exercise equipment, such as: stair climbers, treadmills, exercise bicycles, sit-up devices, rowing devices, complete whole-body exercise devices, and further such devices, may employ the disclosed mechanism in order to facilitate automated collapse.
  • [0011]
    In one embodiment of this invention, an inclined plane complete-body exercise apparatus, such as the apparatus taught in U.S. Pat. No. 6,786,847, utilizes an additional electromechanical mechanism at the foot of the inclined place in order to drive a set of wheels that serve to collapse the apparatus. Upon receiving a command to fold the unit, the vertical translation mechanism raises the inclined plane to its highest position. Then, as the wheels beneath the incline plane rotate, pushing the plane towards the vertical tower, a hinge in the middle of the plane is released, allowing the plane to fold. The vertical translation mechanism is lowered in coordination with the turning of the wheels, such that the apparatus collapses into a “Z-shape,” with the vertical tower forming the uppermost portion of the “Z.” Release of the folded apparatus follows the opposite sequence.
  • [0012]
    In another embodiment of this invention, an inclined plane complete-body exercise apparatus, such as the apparatus taught in U.S. Pat. No. 6,786,847, utilizes an additional electromechanical mechanism at the base of the tower in order to winch a cable that extends from the foot of the inclined plane to the base of the vertical tower. As the cable is winched inwards, the vertical translation mechanism is adjusted to a middle position. The cable's force on the inclined plane causes the hinge in the middle of the plane to be released and, as the wheels of the plane are pulled towards the vertical tower, the apparatus collapses into a “Z-shape”, with the vertical tower forming the uppermost portion of the “Z”. Release of the folded apparatus follows the opposite sequence.
  • [0013]
    In another embodiment of the invention described in the above paragraph, rather than using an additional electromechanical mechanism, the same electromechanical mechanism used by the vertical translation mechanism is coupled with gears, cables, chains, and/or pulleys in order to effectuate the winching effect on the cable. A cable can be used which runs beneath the inclined plane, via pulleys, from the elevating platform to the wheels at the distal end of the inclined plane.
  • [0014]
    In another embodiment of the invention, the same electromechanical apparatus for collapsing is adapted for use with exercise equipment that lacks motorized inclination adjustment.

In FIG. 1A an inclined plane complete-body exercise apparatus 1 is shown along with its constituent parts including the elevating platform 2 and worm gear 3, that serve to elevate and lower the inclined plane and a sliding pad 8 upon which to perform exercises. The inclined plane of the exercise apparatus is divided to a proximate half 4 and a distal half 5, that are connected and articulate with one another by a hinge 6 located in the middle of the inclined plane. Upon receiving a signal to collapse the exercise equipment, an electro-mechanical mechanism located at the distal end of the inclined plane, drives the wheels 7, also located in the distal end of the inclined plane, to drive the inclined plane towards the elevating platform 2 and effectuate collapse of the exercise apparatus 1. The motion of the wheels 7 is coordinated with the motion of the elevating platform 2 such that the exercise apparatus 1 fully collapses upon receiving the signal.

In FIG. 1B an inclined plane complete-body exercise apparatus 1 is shown as the elevating platform 2 is being lowered by the worm gear 3, in order to allow the exercise apparatus to collapse. The proximate half 4 and a distal half 5 are no longer parallel, as the hinge 6 located in the middle of the inclined plane is now bending and the sliding pad 8 collapsing along with the distal half of the inclined plane. The electro-mechanical mechanism drives wheels 7 to drive the inclined plane towards the elevating platform 2 and effectuate collapse of the exercise apparatus 1.
