Definitions

  • This invention relates to step systems for aerobic and cardio-vascular activities.
  • An aerobic step workout is performed by stepping on and off a raised, level step platform.
  • the steps are choreographed, usually performed to music, and leader-driven by an instructor in a class setting or on videotape for home exercise. Workout intensity is largely dependent on the step platform height.
  • step platforms require a user to suspend the workout while an adjustment to height is made. This is disruptive. Additionally, a user who is becoming fatigued and who should probably lower the step height will not do so, and instead will continue the workout, allowing for the possibility of over fatigue and potential miss-step.
  • Another drawback of existing level step platforms is the great amount of load placed on the knee joint while performing the step up to the level platform.
  • the leg is moved forward by hip flexion.
  • the foot is brought up to a position above the level platform by knee flexion.
  • the hip and knee joints go into extension to move the body up against gravity. This places the knee joint under a substantial compression load.
  • most aerobic or cardio-vascular activity such as stepping will cause the participants to perspire. This perspiration has a tendency to pool on the level step platform, creating the potential for injury by slipping on the surface.
  • the ramp is configured to define a front portion, a back portion, an upper workout surface portion, and an underside portion.
  • the incline of the ramp can be provided in various ways, with adjustable legs or other incline members being preferred so that the incline of the ramp can be altered.
  • the legs can be permanently or removably attached to the underside portion of the ramp proximate to the back portion thereof.
  • adjustable legs can also be mounted to the front portion of the ramp so as to allow the overall height of the ramp to be varied.
  • the ramp can also have one or more additional features, such as a radiussed leading edge on the ramp's front portion for contacting an independent support surface.
  • the ramp can be formed with grooves that channel perspiration from the upper work surface portion of the ramp and serve to visually divide the ramp into multiple workout areas, such as a central workout area and two lateral workout areas.
  • Each workout area can be color-coded so as to allow a user to follow a choreographed routine.
  • the front of the center workout area may be recessed relative to the lateral workout areas so as to facilitate easier access to all workout areas by the user.
  • the upper workout surface portion is preferably configured with a non-slip surface.
  • Fig. 2 is a rear perspective view of the step exercising system of Fig. 1;
  • Fig. 3 is a side elevation view of the step exercising system of Fig. 1;
  • Fig. 4 is a detailed perspective view of an exemplary height adjustable incline member for the step exercising system of Fig. 1 ;

  • Fig. 16 is a cross-sectional view of the adjustable leg, taken along line 16-16 of Fig. 14, showing the leg in an extended position;
  • Fig. 17 is an exploded, perspective view of the adjustable leg of the step exercise system of Fig. 8;
  • Fig. 18 is a cross-sectional view of the adjustable leg, showing the spring resistance means.
  • Fig. 19 is a cross sectional view, taken along line 19-19 of Fig. 9.
  • a step exercising system 2 in accordance with a first exemplary embodiment of the invention is shown at rest on a support surface S (see Fig. 3), such as a floor.
  • the step exercising system 2 includes a portable inclined aerobic step ramp 10, whose overall configuration is best shown in Figs. 1 and 2.
  • the ramp 10 can be made of any suitable material capable of supporting a person stepping thereon. Examples include but are not limited to plastics such as ABS (acetyl butyl stylrene), polyethylene or the like.
  • the ramp 10 can be formed with such materials using a blow mold technique, pressure forming, or injection molding.
  • other material such as metal (e.g. aluminum) could be used to form the ramp 10.
  • the ramp 10 may be constructed in various configurations, depending on design preferences. Such shape variations notwithstanding, the ramp will generally define a front portion 12 adapted to face a user and a back portion 14 that lies away from the user. The ramp 10 will further define an upper workout surface portion 20 and an underside portion 22. As can be seen in Fig. 3, the back portion 14 is positioned at a height which is above the front portion 12 relative to the support surface S, such that the upper workout surface portion 20 is inclined toward the person at a constant angle during use. Moreover, the leading edge 24 of the front portion 12 preferably rests on the support surface S, so as to facilitate easy stepping onto the ramp 10.
  • the ramp 10 will preferably be constructed such that the incline of the upper workout surface portion 20 has about a 10-30 degree angle relative to the support surface S.
  • An angle of incline less than about 10 degrees will be too small to facilitate an adequate workout, and an angle greater than about 30 degrees will be too large to enable the user to step securely up onto the ramp 10 and will tend to hyper extend the achilles tendon.
  • the inclined configuration of the ramp can be provided in various ways. In Figs. 1-3, the incline is provided by mounting incline members in the form of adjustable legs 26 to the underside portion 22, proximate to the back portion 14. Other types of incline members could also be used, such as non-adjustable legs, frames, blocks, or otherwise. Another alternative would be to form the ramp 10 as a wedge-shaped structure in which the back portion 14 is thicker than the front portion 12.
  • the legs 26 in the ramp embodiment of Figs. 1-3 can be made of any suitable material capable of supporting a person, including plastics as described above, and metals.
  • the legs 26 can be attached to the underside portion 22 in any suitable fashion.
  • the ramp 10 is molded, the legs 26, or a portion thereof, could be integrally formed with the ramp 10 during the molding process so as to be built-in to the ramp 10.
  • Other alternatives include attachment by welding, bolting, threading or the like, depending on whether the legs are to be permanently or removably attached to the ramp 10.
  • the legs 26 are constructed with a height adjustable feature so that the incline angle of the ramp 10 can be altered.
  • Fig. 4 illustrates one example of a leg 26 having height adjustment capability. As shown in Fig.
  • the leg 26 comprises an inner tubular member 31 that is slidably disposed within, and surrounded by, an independent outer tubular member 33 that is attached to the ramp 10.
  • the inner tubular member 31 is thus capable of telescoping from the outer structure 33, allowing for a change in length of the leg 26.
  • the inner tubular member 31 may be secured in position relative to the outer tubular member 33 in various ways.
  • the outer tubular member 33 is constructed with a slotted opening 35 and the inner tubular member 31 is constructed with a protruding pin member 37 that is received in the slotted opening 35.
  • the slotted opening 35 includes two horizontal channels 41 connected by a vertical channel 43.
  • the inner tubular member 31 is rotated so that the pin member 37 can be slid from a fixed point 45 in one of the horizontal channels 41, then through the vertical channel 43 of the slotted opening 35, and to another fixed position 47 in the other horizontal channel 41.
  • additional horizontal channels 41 can be provided depending on the number of height adjustments desired.
  • Other adjustment arrangements could also be used, including pins inserted through holes in the inner tubular member 31 and outer tubular member 33.
  • the legs 26 can further be mounted with a slip-resistant tip 49 at the end, which rests on the support surface S.
  • the tip 49 may be made of any suitable slip-resistant material, including but not limited to silicone rubber, high friction plastic, or otherwise.
  • the front portion 12 of the ramp 10 may be constructed with a radius on the leading edge 24. The radius enables the leading edge 24 to contact the support surface S without damaging it, as might be the case from a squared edge. The radius also facilitates ramp angle changes by allowing the leading edge 24 to contact the support surface at various locations. In addition, the radius provides a friendlier contact surface with a user.
  • a second embodiment of the ramp 10 is shown wherein the underside 22 mounts adjustable legs 52 proximate to the front portion 12 of the ramp 10.
  • the adjustable legs 52 directly contact the support surface S and enable the leading edge 24 to be positioned above the support surface rather than resting directly thereon. This allows a user to intensify the workout by having a higher initial starting point for the workout.
  • the upper workout surface portion 20 of the ramp 10 comprises grooves 54 that divide the surface into visually distinct workout areas.
  • the grooves 54 can be formed in a variety of ways. If the ramp 10 is formed as a single unit, the grooves 54 can be formed therein during the fabrication process or thereafter in subsequent processing. Alternatively, the grooves 54 could be defined by fabricating the ramp 10 as separate sections that are suitably fastened together such that a space is formed between adjacent sections to define the grooves 54. In the embodiments of Figs. 1-3 and 5, the grooves 54 divide the upper workout surface portion 20 into three visually distinct workout areas, namely, a center workout area 55 and two distinct side workout areas 56 adjacent to the center workout area 55.
  • the workout areas 55 and 56 can be color-coded.
  • the workout areas 55 and 56 are also preferably constructed with a non-slip surface configuration.
  • the non-slip configuration could be provided by suitably texturing the upper workout surface portion 20 in its initial construction.
  • the non-slip configuration can be provided by a separate material that is directly applied to the workout areas 55 and 56 after initial construction, as by spraying, brushing, or adhering. Examples include, but are not limited to, textured paints, rubber coatings, or various inserts or stickers made of rubber, sand paper, or other materials.
  • a third embodiment of the portable inclined aerobic step ramp 110 of the present invention includes a plurality of adjustable legs 126 affixed to an underside portion 122 and are preferably disposed adjacent to a peripheral edge 113 of the underside portion 122.
  • the center and side workout areas 55, 56 preferably include non-slip panels 190, 194 formed of resilient material.
  • the non-slip panels 190, 194 preferably have textured upper surfaces 196, 198.
  • the lower surfaces 200, 202 of each non- slip surface 190, 194 preferably have elongated recessor channels 206 disposed at substantially regular intervals and aligned substantially parallel to the front portion 112 of the main body 111. It can be appreciated that material above the channels 206 is thinner than the material intermediate the channels 206. When subject to load, the resilient, non- slip panels deflect downwardly. The upper surface of the non-slip panels in the area above the channels 206 deflect a greater amount than the areas intermediate the channels 206.

Abstract

Cette invention concerne un système de marche d'exercice permettant d'effectuer une séance d'exercices d'aérobie consistant à monter et à descendre d'une marche. Ce système est conçu sous la forme d'une rampe de marche inclinée portative. Cette rampe est inclinée en direction d'un utilisateur de sorte que celui-ci puisse monter sur la rampe à différentes hauteurs, ce qui permet de régler le niveau d'intensité de la séance d'exercices sans avoir à interrompre la séance d'exercices pour ajuster la hauteur de la marche, comme c'est le cas pour une marche d'exercice d'aérobie classique comportant une plate-forme surélevée.
