DEVICE FOR UTILIZATION OF THE ENERGY GENERATED BY BODY
WEIGHT
Field of the Invention
The present invention refers to a device for utilization of the energy generated by pressure of body weight on the heals of footwear to be utilized at the moment of the final detachment of the footwear from the ground. Background of the Invention
Up to the present date, a great quantity of air chambers located on the sole of footwear are known in the art. Those air chambers are generally located on the back portion of the sole, that is, in the heal, and serve to absorb the shock of the foot against the ground at the moment the user is exercising, be him walking or running. However, the present invention was designed with the objective of utilizing the energy generated by the pressure of the body weight on the heal of the footwear, comprising inside a compression bellows, in order to be utilized through a device comprising valves and a retainer, at the moment of the final detachment of the footwear from the ground by the means of an expansion bellows.
Objective of the Invention
The objective of the present invention is attained by the means of an air (or any other gaseous element) compression bellows within the sole of the footwear, and once the foot is set on it, a pressure is generated and is conducted by a compressed air (or any other gaseous element) retainer, which through an aft retaining valve retains the gas in place, producing, when transmitting the body weight to the front part of the foot, the opening of an aft retaining valve placed on the aft portion of the compressed air (or any gas) retainer, delivering the pressure to the front end of the sole of the footwear
producing the expansion of the expansion bellows and, therefore, producing assistance at the time of the detachment of the foot from the ground, releasing, afterwards, the pressure through a flush valve or an exhaust, placed on the front portion of the sole of the footwear. It is important to mention that the invention can be embodied by on or more parallel systems within the same sole of the footwear, or one or more compression bellows, or one or more admission, retaining or flush valves, and one or more expansion bellows.
Brief Description of the Drawings In order to make the object of the invention easier to understand, the invention is illustrated with 6 Figures, which are used as a demonstrative example, being:
- Figure 1 a top section view of the sole of the footwear, showing the open system; - Figure 2 a side section view of the sole of the footwear, showing the open system;
- Figure 3 a side section view of the sole of the footwear, but in an embodiment different from the one shown on Figures 1 and 2, showing the open system; - Figure 4 a top section view of the sole of the footwear, but in an embodiment different from the one shown on Figures 1 and 2, showing the open system;
- Figure 5 a side section view of the sole of the footwear, showing the closed system; - Figure 6 a top section view of the sole of the footwear, showing the closed system.
Detailed Description of the Preferred Embodiment As shown on Figures 1 to 6, the invention comprises seven elements: the compression bellows (A), the compressed air (or any type of compressed gas) retainer (B), the expansion bellows (C), the air (or any other gaseous element) admission valve (M), the aft retaining valve (K), the fore retaining valve (P) and the flush or exhaust valve (T).
In order to better understand the invention, reference is made to Figure 1 which shows the profile of the sole of a footwear on a top section view and Figure 2 which shows the same profile on a side section view, and said sole comprises, on its aft portion, a compression bellows (A) which, on its turn, comprises on its fore end a valve (M) of admission of air (or any other gaseous element) and on the front end of the same compression bellows (A) there is an aft retaining valve (K), which through a small duct flows into a retainer (B) of compressed air (or any type of compressed gas), flowing into, through another duct, the expansion bellows (C) that comprises a fore retaining valve (P) driven by pressure, and the same expansion bellows (C) comprises, on its fore end, a flush or exhaust valve (T) driven by the pressure release. Even though the present invention is described in detail, it is important to understand that is not limited in application to the details and parts herein described. The invention is capable of having other embodiments and of being carried out with one or more parallel systems within the same sole of footwear, or one or more compression bellows, or one or more admission, retaining or flush valves, and/or one or more expansion bellows, and, therefore, it can be carried out in several different embodiments. One must understand that the terminology used in the present patent description
has only an illustrative purpose, not limiting the scope to the present invention.
Having described and specified the nature and scope of the invention and its preferred embodiment, the following claims are made of exclusive rights and property.
