Description
    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The present invention relates to jogging mats and in particular to a cushioned multi-level jogging mat which varies in thickness from a lower anterior foot portion through a beveled, sloped or vertical mid section to a raised posterior foot portion for complete impact absorption during jogging in place.
  • [0003]
    2. Description of the Prior Art
  • [0004]
    This invention concerns a device which is designed specifically for in-place jogging and running. According to Runner's World Magazine, running is most popular sport in the world. Running and jogging improve and maintain cardiovascular health, lower body strength, as well as mental and overall physical health. For active runners, it is important to keep a regular training schedule which often involves 3-6 days a week, in order to maintain or improve performance.
  • [0005]
    There are different types of in-place running and simulated running devices on the market. The most popular type is the treadmill. However, due to the cost to acquire the machine and space requirement, many people do not have the luxury of owning a treadmill. Besides the treadmill, there are other exercisers that simulate actual jogging and running to a certain extent. Yet many of them do not capture the essential elements of the jogging and running motion.
  • [0006]
    The actual running motion involves 3 stages of foot motion. First, there is the heel landing and striking stage. Then, there is a midstance stage in which the front and back of the foot are in contact with the landing surface. As the body moves forward, the heel lifts and the toes propel the body until the heel of the opposite foot strikes the ground.
  • [0007]
    All prior patents related to this application consisted of devices having flat foot contact surface. A flat surface in-place jogging running device with a non moving contact surface, does not truly allow the 3 stages of foot motion to occur. During in-place jogging or running on a non moving surface, as the center of gravity of the body moves vertically from the ground, the landing phase of the foot and propelling phase are done by the toes. Since our natural foot anatomy is adapted for the three stages of motion described above, landing on the toes on a flat surface increases strain on the foot. As a result, prolonged in-place jogging or running on a non moving flat surface, can cause increased strain and even premature injury to the foot.
  • [0008]
    There were several patents granted for devices utilized shock absorbing and resilient materials, and were designed for in-place walking, jogging and running.
  • [0009]
    U.S. Pat. No. 4,253,661, issued Mar. 3, 1981 to Russell, provides a leg exercising device comprising a thick, resilient, flexible pad with a sloped top surface and sloped sides which reportedly provides for safe, non-jarring leg exercises involving running, squatting, squat-running, leg joint pivoting, balance and the like. Russell also has two other patents with side-by-side pads: U.S. Pat. Nos. 4,603,851 and 5,656,000. However the foot always lands on a flat surface.
  • [0010]
    U.S. Pat. No. 4,159,826, issued Jul. 3, 1979 to Hancock, claims a pneumatic jogging platform with resilient tubing under the pad and a flat surface.
  • [0011]
    U.S. Pat. No. 3,641,601, issued Feb. 15, 1972 to Sieg, shows a two pad device for walking, jogging and running exercise with flat surfaces.
  • [0012]
    U.S. Pat. No. 3,634,895, issued Jan. 18, 1972 to Childers, describes a flat broad pad inside a frame.
  • [0013]
    U.S. Pat. No. 1,931,146, issued Oct. 17, 1933 to Hampel, discloses a pad with corrugations for exercise having a flat landing surface.
  • [0014]
    None of the above patents has a multilevel surface with a beveled middle section suited for natural jogging and running motion.
  • SUMMARY OF THE INVENTION
  • [0015]
    A primary object of the present invention is to provide a cushioned multilevel jogging mat with an elevated heel cushion for anatomically corrected in-place jogging or running simulating the three stages of foot motion during actual running and jogging.
  • [0016]
    Another object of the present invention is to provide a cushioned jogging running mat that is inexpensive, portable, easy to store and more importantly, easily accessible.
  • [0017]
    One more object of the present invention is to provide a cushioned jogging and running mat that reduces jarring and impact to the joints in legs during simulated jogging and running.
  • [0018]
    An additional object of the present invention is to provide a cushioned jogging and running mat that can be used by a wide group of users across different recreational interests and experiences.
  • [0019]
    A further object of the present invention is to provide an alternate replacement for a more expensive treadmill.
  • [0020]
    An added object of the present invention is to provide a low impact exercise device for rehabilitation purposes.
  • [0021]
    Still a further object of the present invention is to provide a cushioned jogging and running mat that reduces the impact transmitted to the supporting surface and thereby reduces noise, so that disturbance to others can be minimized.
  • [0022]
    Yet one more object of the present invention is to provide various models having different heights and different inclines for various types of individuals having different needs and for different applications, such as low impact walking or high impact fast running in place.
  • [0023]
    Still one more object of the present invention is to provide a compact model having only the inclined section and the elevated heel section and utilizing the supporting surface, such as a rug or a rubber mat, as the toe portion.
  • [0024]
    In brief, the present invention provides a multilevel cushioned mat that simulates the three stages of foot motion in running and jogging while cushioning the impact on the feet and provides a solution to reduce strain on the foot during in-place jogging or running. The elevated section in the rear portion of the mat allows the heel to land with full shock absorption on the cushioned mat. After a very short midstance with the foot on the sloping beveled portion or vertical portion or curved portion making the transition between heel contact and toe contact, the body weight can be quickly transferred to the toes on the lower front flat section of the mat or underlying floor surface and lift the body upward. In this manner, the full motion of jogging or running is accomplished.
  • [0025]
    Various models are provided having different heights and different inclines for various types of individuals having different needs (such as children, fit adults, heavy adults, elderly) and for different applications, such as a slight incline with a relatively low heel section for low impact walking or slow jogging in place, a more inclined midsection with a moderately elevated heel section for greater impact jogging in place, and a sharply inclined midsection and substantially elevated heel section for high impact fast running in place.
  • [0026]
    A compact model has only the inclined section and the elevated heel section and utilizes the supporting surface, such as a rug or a rubber mat, as the toe portion. This model can easily be stored in a brief case or drawer and pulled out for in place walking, jogging or running workouts.
  • [0027]
    The primary advantage of the present invention is that it provides a solution for an anatomically corrected in-place jogging and running motion on a non moving surface, actually simulating the three foot motions of jogging and running while cushioning the foot.
  • [0028]
    A secondary advantage of the present invention is that it allows a convenient access to a 15-45 minutes workout at a flexible location.
  • [0029]
    Another advantage of the present invention is that it is inexpensive, portable and anatomically corrected and suited for all users across different recreational interests and skill levels.
  • [0030]
    An additional advantage of the present invention is that it is shock absorbing to lessen impact.
