DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
With reference initially to FIGS. 1-16, an embodiment of a foot platform assembly 90 including a pair of foot platforms 100 for an exercise device 110 will be described. Although the foot platforms 100 will be described in connection with jumping and exercise on an inclined exercise device 110, in alternative embodiments, the pair of foot platforms 100 may be used in conjunction with horizontal exercise devices (e.g., Pilates exercise machines) and/or other types of exercise/physical therapy devices. Further, the pair of foot platforms 100 may be used with squat exercises or other exercises/therapies other than jumping.
The exercise device 110 comprises a sliding platform or glide board 155 slidably mounted on inclined rail(s) 156 which are secured to a base support tube 158 at their lower ends and are supported in desired inclined orientation at a selected inclination angle by an adjustable support assembly 160 that allows the rails 156 to be adjusted to a desired inclination angle.
With reference to FIGS. 2 and 3, the foot platforms 100 are mounted to the base support tube or support base 158 of a main frame assembly 159 adjacent to the lower ends of the foot platforms 100 via a pair tubular sockets 170. The tubular sockets 170 receive reduced-diameter strut tubes 180, which are coupled to spring support tube 190 via larger-diameter strut tubes 192. Round plastic tube caps 200 are used to cap the ends of the strut tubes 180 and square plastic tube caps are used to cap the opposite ends of the spring support tube 190.
With reference to FIGS. 2-16, the foot platforms 100 each include a H-shaped tubing support assembly 210 with H support blades 212, H support base tube 214, and plastic tube cap 216. The H support base tube 214 includes a centrally disposed rectangular mounting section 220. The H-shaped tubing support assembly 210 is connected to a rear of a rectangular plastic molded front foot platform member 230. An opposite side or front of the front foot platform member 230 includes treads 240 that one's feet engage during use. A rectangular plastic molded rear foot platform member 250 includes a centrally disposed rectangular hole 260 that receives the rectangular mounting section 220 of the H-shaped tubing support assembly 210. The rear foot platform member 250 is connected to the front foot platform member 230 via a plurality of threaded fasteners 260.
Two pairs of leaf springs 270 are connected at one end to a front face 280 of the spring support tube 190 with threaded fasteners 290 and are connected at an opposite end to centrally disposed rectangular mounting section 220 of the H-shaped tubing support assembly 210 with threaded fasteners 300.
The foot platform assembly 90 will now be described in use. With the rails 156 preferably at an incline, a user lies with one's back on the glide board 155 with one's head near a top of the inclined rails 156. The user puts the bottom of one's shoes/feet on the treads 240 of the foot platforms 100. The user bends and extends one's legs, pushing off of the foot platforms 100 with one's feet to move one's torso on the glide board 155. The individual, separate leaf springs 270 connected to the respective foot platforms 100 give each foot platform 100 a springy, resilient feel when the user presses and/or bounces off the foot platforms 100 with one's feet. Additional variations involve using only one foot on one foot platform (as opposed to two feet contacting both foot platforms 100 simultaneously), alternating contact of one foot on one foot platform followed by contacting another foot on the other foot platform, and/or positioning the foot/feet in various locations and/or orientations on each foot platform 100. To vary resistance when jumping or pressing off of the foot platform assembly 90, a user may vary the angle of the rails 156 with the adjustable support assembly 160. The steeper the angle of the rails 156, the greater the resistance and vice versa. Examples of exercises that can be performed on exercise device 110 using the foot platform assembly 90 include, but are not limited to, squat exercises, bridge squat exercises, plyometric squat exercise, sprinters, and/or other exercises/therapies. Although generally a user would use the exercise device 110 and the foot platform assembly 90 with the rails 156 in an inclined orientation, the user may use the exercise device 110 and the foot platform assembly 90 with the rails 156 in horizontal or substantially horizontal orientation where the rails 156 are parallel with or substantially parallel with the ground.
Advantages of the foot platform assembly 90 include:
the foot platform assembly 90 provides an alternate stepping motion that is concentric and eccentrically loaded—an alternating motion with the legs in a stepping motion to enhance balance and stepping strength;
the foot platform assembly 90 can also be used with both feet simultaneously in all the different postures and variations of squat or plyometric squat (jumping) exercises;
the foot platform assembly 90 provides for good cardio exercise;
the alternating use of the foot platform assembly 90 as a cardio exercise for a short period and then quickly using the inclinable exercise device 110 for other strength exercises, then quickly returning to the cardio and repeating, is possible;
the soft landing achieved by absorbing energy in the springs 270 of the foot platform assembly 90 reduces joint stress, allowing greater muscle exercise; and
the springs 270 of the foot platform assembly 90 also allows independent walking, jogging, and like exercise with the same zero impact forces.
The above figures may depict exemplary configurations for the invention, which is done to aid in understanding the features and functionality that can be included in the invention. The invention is not restricted to the illustrated architectures or configurations, but can be implemented using a variety of alternative architectures and configurations. Additionally, although the invention is described above in terms of various exemplary embodiments and implementations, it should be understood that the various features and functionality described in one or more of the individual embodiments with which they are described, but instead can be applied, alone or in some combination, to one or more of the other embodiments of the invention, whether or not such embodiments are described and whether or not such features are presented as being a part of a described embodiment. Thus the breadth and scope of the present invention, especially in any following claims, should not be limited by any of the above-described exemplary embodiments.
Terms and phrases used in this document, and variations thereof, unless otherwise expressly stated, should be construed as open ended as opposed to limiting. As examples of the foregoing: the term “including” should be read as mean “including, without limitation” or the like; the term “example” is used to provide exemplary instances of the item in discussion, not an exhaustive or limiting list thereof; and adjectives such as “conventional,” “traditional,” “standard,” “known” and terms of similar meaning should not be construed as limiting the item described to a given time period or to an item available as of a given time, but instead should be read to encompass conventional, traditional, normal, or standard technologies that may be available or known now or at any time in the future. Likewise, a group of items linked with the conjunction “and” should not be read as requiring that each and every one of those items be present in the grouping, but rather should be read as “and/or” unless expressly stated otherwise. Similarly, a group of items linked with the conjunction “or” should not be read as requiring mutual exclusivity among that group, but rather should also be read as “and/or” unless expressly stated otherwise. Furthermore, although item, elements or components of the disclosure may be described or claimed in the singular, the plural is contemplated to be within the scope thereof unless limitation to the singular is explicitly stated. The presence of broadening words and phrases such as “one or more,” “at least,” “but not limited to” or other like phrases in some instances shall not be read to mean that the narrower case is intended or required in instances where such broadening phrases may be absent.
