Abstract

A complete energy absorbing system for a variety of items, including athletic shoes. To accomplish the foregoing, the invention utilizes a series of encapsulated springs that are always in a state of suspension. In the preferred mode, the encapsulated springs are conical in nature, providing the utmost in strength and support while preventing the springs from bottoming out upon impact. Such is a result of the unique stiffening of the conical spring during compression thereof. Importantly, as distinguished from the prior art, an encapsulating material placed around a plurality of conical springs prevents the springs from being continually placed in a stressed situation, thus maintaining their structural integrity. Such encapsulating material may be made of a polymeric or thermoplastic material, which conforms to the conical shape of the springs and their respective apertures, functioning to aid in the dissipation of impact forces. The uniqueness of the encapsulation of the springs is that such a configuration allows for specific designs, lengths, and widths, as well as ease of placement in pre-formed openings in the padding or encapsulating material for the manufacture of the final product. Because the springs work in conjunction with one another, and because the springs work in conjunction with the encapsulating material, the present invention provides a durable, long-lasting system that allows for previously-unattained stability and comfort.

10. U.S. Pat. No. 5,502,901, invented by Brown, entitled “Shock Reducing Footwear And Method of Manufacture”

The Brown invention is an article of footwear which has an outsole with a cavity in the heel region in which a cushioning insert is installed to cushion impacts and provide added lift to the wearer. The heel region of the outsole projects outwardly beyond the periphery of the heel region of the shoe upper to form a projecting peripheral rim. The cavity has an upper wall and a lower wall and a plurality of springs extend between the upper and lower walls at spaced intervals around the peripheral rim. Opposing magnets are mounted in the upper and lower walls in a central region of the cavity with their like poles facing one another to provide a magnetic biasing force which augments the spring load.

The aforementioned prior art patents illustrate various spring designs, including: a method for forming a resilient bladder structure, including fluid therein, for use in the sole of footwear; various cushions in particular pre-shaped forms; spring-cushioned shoes utilizing a very small quantity of springs; cushioned shoes utilizing air bladders; shock absorption assemblies for increasing stability and shock absorption of the heel in particular; spring assemblies utilizing solid plates; and sport shoes having a spring biased heel with operator insertable foam inserts for varying the biasing ability of the heel.

In contrast to the above, the present invention creates a complete energy absorbing system for a variety of items, including shoes, by utilizing a series of encapsulated conical springs that are always in a state of suspension. The top and bottom part of each spring are flat, allowing the encapsulating material therearound to maintain its structural integrity. The springs are conveniently placed within conical pre-formed openings in the padding and the height of the springs varies from a heel of a shoe to the arch and to the sole, with the tallest springs located in the heel area. The springs are placed between the inner and outer sole in the same manner to the heel area, to provide increased absorption of forces in a widespread area.

Thus, the “floating” mechanism of the present invention can reduce the force experienced by the body to a level better than 50%, due to the complete control of the design of the spring, that does not change its resilience characteristics during its usage and application.

In alternate embodiments, the floating system is applied to protective helmets and equipment including, but not limited to crash mats and gymnastic mats, which typically lose their resilience over a protracted period of time. Regarding helmets, the encapsulated conical spring system may be placed in a series of pre-formed openings in the padding under the shell. The height of the spring varies with the location, with the neck area comprising the shortest, and the crown of the head comprising the longest springs. Therefore, in total, the springs of the present invention can be designed to absorb and dissipate higher energy forces than any preexisting system used in any sport.

SUMMARY OF THE INVENTION

As noted, the purpose of the present invention is to create a complete energy absorbing system for a variety of items, including athletic shoes. To accomplish the foregoing, the invention utilizes a series of encapsulated springs that are always in a state of suspension. In the preferred mode, the encapsulated springs are conical in nature, providing the utmost in strength and support while preventing the springs from bottoming out upon impact. Such is a result of the unique stiffening of the conical spring during compression thereof. However, additional non-cylindrical springs, such as ribbon-shaped, bell-shaped, and other styles of spring may also be utilized.

Importantly, as distinguished from the prior art, an encapsulating material placed around a plurality of conical springs prevents the springs from being continually placed in a stressed situation, thus maintaining their structural integrity. Such encapsulating material may be made of a polymeric or thermoplastic material, which conforms to the conical shape of the springs and their respective apertures, functioning to aid in the dissipation of impact forces.

The uniqueness of the encapsulation of the springs is that such a configuration allows for specific designs, lengths, and widths, as well as ease of placement in pre-formed openings in the padding or encapsulating material for the manufacture of the final product. Because the springs work in conjunction with one another, and because the springs work in conjunction with the encapsulating material, the present invention provides a durable, long-lasting system that allows for previously-unattained stability and comfort.

In general, placement of springs in prior art fixtures impedes production of the final product, impedes stabilization of the spring in place, allows for only a limited number of springs to be utilized, and results in a lack of “float” sensation for the user.

Thus, the configuration of the present invention solves a well-known problem in the prior art, where repetitive injuries are common. A runner's feet, for example, collide with the ground 800 to 2000 times per mile, or 50 to 70 times per minute for each foot, at a force of three to eight times body weight (depending on the terrain and the runner's weight). The impact at the foot surface interface is absorbed by the running shoe or transmitted directly to the athlete's leg and back. While a person is running, minor anatomic and bio-mechanical abnormalities that are of no significance in walking can produce injury.

In the present invention, then, it is important to note that the height of the conical springs may vary, such as a variance from a heel of a shoe to the arch and to the sole, with the tallest springs located in the heel area. This provides increased absorption of forces in a widespread area, much to the benefit of the user. The encapsulated springs are further placed in a series of conically-shaped pre-formed openings in the heel, arch and sole areas and placed between the inner and outer sole area in the same manner to the heel area, to alleviate the above problem.

Thus, the “floating” mechanism of the present invention can reduce the force experienced by the body to a level better than 50%. Such is due to the complete control of the design of the spring, that does not change its spring or resilience characteristics during its usage and application. The present assembly is designed so that the user feels in suspension, or “floating,” at all times.

The floating system will also benefit older or more fragile athletes, as pre-existing athletic shoes particularly fail to absorb sufficient forces when used on hard surfaces, such as all-weather tennis courts. Many athletes' knees injure easily, and the present invention will eliminate or minimize those injuries significantly.

It should also be noted that the “floating” mechanism is especially important for runners in that the heel of the runner strikes the ground first. The floating design aids in the absorption and dissipation of forces for runners and pronate and/or suppinate. To render the assembly appropriate for all athletes, in some instances, minimal or no “floating” mechanism may be required in just the sole area.

The floating system can also be applied to protective helmets and all types of protective equipment used in sports including, but not limited to crash mats and gymnastic mats. It is a known fact that mats of all types lose their resilience over a protracted period of time. The benefits of the floating design as applied to a mat system is that the same would not lose resiliency, and the spring assembly can be designed to absorb and dissipate more forces than the pre-existing mats, such as absorbing forces within specific pre-determined ranges.

With reference to items such as helmets, the encapsulated conical spring system may be placed in a series of pre-formed openings in the padding under the shell. The height of the spring in such an embodiment varies with the location on the head, with the neck area comprising the shortest, and the top of the head comprising the longest springs. Therefore, in total, the springs of the present invention can be designed to absorb and dissipate higher energy forces than any preexisting system used in any sport or activity.

Depending upon the exact environment in which the same are to be used, the conical springs may be constructed of polymers or metals including titanium and steel—lightweight, yet durable materials to accomplish the purposes of the invention.

Importantly, the springs are spread throughout the area to be protected and work in conjunction with one another, providing a completely controlled protected area to effectively absorb and dissipate forces upon impact.

In any such embodiment, the stiffness of the springs of the invention may be tailored to an appropriate degree according to the type of activity in which the invention is utilized. As previously noted, such stiffness is inherently enhanced by the conical shape of the springs utilized in the preferred mode.

Thus, in total, the present invention lessens the incidence and severity of injury in a great variety of sporting activities, at low costs and with ease of manufacture and installation.

Therefore, it is the object of the present invention to provide a unique spring assembly for usage on footwear, protective equipment, floors, boards, walls, and other surfaces, for the purpose of enhancing absorption and dissipation of impact forces.

It is specifically the object of the present invention to provide an assembly utilizing a plurality of springs encapsulated within padding material, such that impact forces are spread out and distributed widely for the benefit of the user.

It is a further object of the invention to provide a conical spring assembly that is manufactured in a variety of previously determined sizes, so as to render the same effective for a host of sporting activities and additional applications where such protection is desired.

It is also an object of the present invention to provide an impact and energy absorbing assembly that requires less padding material to be used, thus reducing the weight of the item in question.

It is generally an object of the present invention to provide an impact and energy absorbing assembly that is relatively inexpensive to manufacture.

It is further an object of the present invention to provide an impact and energy absorbing assembly utilizing conical springs that provide strength and durability for longer periods than the springs utilized by the prior art.

The novel features which are considered characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of the embodiments when read and understood in connection with accompanying drawings.

BRIEF DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 is a side perspective, partial cut-away view of a full athletic shoe incorporating the enhanced floating system therein. [0051]
FIG. 2 is a rear partial cut-away view of the heel portion of the athletic shoe shown in FIG. 1. [0052]
FIG. 3 is a three-quarter, partial cut-away view of a helmet incorporating the present invention. [0053]
FIG. 4 is a top cut-away view of the enhanced floating system, illustrating conical springs encapsulated within conical apertures therefor. [0054]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

This description relates to the general comments herein, as well as the four figures referred to above. As noted, FIG. 1 is a side perspective view of a full athletic shoe incorporating the enhanced floating system therein. Included in the figure are the primary components of the assembly: upper layer ([0055] 12), lower layer (14), padding (16), conical apertures within the padding (18), conical springs (20) within the conical apertures. In FIG. 1, the assembly is incorporated into an athletic shoe or sneaker (22), which includes a heel portion (24), mid-portion (26), and toe portion (28).
In the preferred mode, a plurality of conical spring members ([0056] 20) are uniquely encapsulated in conical apertures (18) within the padding (16) in a previously-determined area of the sneaker (22). Unlike the prior art, a large quantity of springs may be utilized and the length of the springs varies, with the longer springs (20) appearing at the heel portion of the shoe (24) and gradually shorter springs (20) appearing towards the mid-section (26) of the shoe. The number of springs utilized creates a system for great distribution and spreading of forces, thereby reducing the adverse effects of impact in a manner previously unattained. The particular quantity and location of the conical springs in FIG. 1 are shown for example purposes only, and the springs may be located along the entire athletic shoe, including to the toe portion thereof (28), if desired by the manufacturer.
Importantly, the presence of padding surrounding the conical springs and working in conjunction with them prevents the springs from bottoming out, or reaching their full capacity of energy absorption. Furthermore, the assembly provides for complete memory, which is instantaneous upon release of the force exerted. In addition, the configuration functions to allow the outer portion of the assembly to receive primary forces, with the conical springs receiving secondary forces, the padding receiving additional forces, and only remaining dissipated forces distributed to the user. As such, the assembly compresses in a unique manner to absorb the impact of humans coming in contact therewith. [0057]
Specifically, the configuration allows for the entire series of conical springs of varying sizes to work in unison, as opposed to a single spring or limited number of springs attempting to absorb all forces received. This simply allows for a far greater amount of energy absorbed by the assembly of the present invention. Thus, regarding the present invention embodied within an athletic shoe, the floating system will mitigate the incidence metatarsal pain and a host of particular injuries. [0058]
Consistent with the foregoing, FIG. 2 is a rear view of the heel portion of the athletic shoe ([0059] 24) shown in FIG. 1, illustrating that multiple conical springs (20) may be utilized along the width of the heel, also unlike the prior art. As noted, this configuration provides the utmost in impact and energy absorption, and the length of the springs across the heel width may also vary to compensate for the varying angles at which users land thereon. Such is especially the case, given the stiffness resulting in the conical springs upon compression thereof.
The incorporation of the present invention into the heel of the athletic shoe is especially important, given the degree of force placed upon the user's heel repetitively during activities such as running and tennis. [0060]
Next, FIG. 3 is a three-quarter, partial cut-away view of a helmet ([0061] 30) incorporating the present invention, illustrating a plurality of conical springs (20) encapsulated in conical apertures (18) within the padding (16) to provide enhanced impact and energy absorption. The drawing represents the configuration by which the springs are incorporated, and such springs may be located anywhere within the helmet, such as the crown area, forward surface, rear surface, and both sides. Consistent with the description of FIG. 1, the length of the springs varies, with longer springs appearing at particularly sensitive portions and gradually shorter springs appearing outwardly therefrom.
The depiction of the invention within a football style helmet is for example purposes only, as the encapsulated springs may also be utilized on items such as chest protectors, shin guards, shoulder pads, knee pads, elbow pads, and a host of crash mats, boards, floors, walls, and other flat surfaces. [0062]
It should be noted that when two separate devices, each incorporating the assembly of the present invention, collide with one another, the level of energy absorbed and dissipated by the present invention is even greater than the already beneficial result received through usage of just a single such device. [0063]
Thus, to use the example depicted in FIG. 3 herein, helmet-to-helmet type collisions are common in many contact sports such as football and hockey, and usage of the aforementioned helmets by all players within a game will only reduce the incidence of severe injury by that much more. [0064]
Finally, consistent with all of the foregoing, FIG. 4 is a top cut-away view of the present invention, illustrating a plurality of conical springs ([0065] 20) encapsulated within corresponding conical apertures (18) within the padding (16) to provide enhanced impact and energy absorption. As depicted, the apertures are pre-formed within the padding or polymeric material, and each bear a unique conical shape in order to effectively receive and contain the conical springs in a secure manner.
In regards to all FIGURES, the spring assembly comprises a previously-determined quantity of springs, such quantity selected according to the needs of any of a host of particular applications. For example, differing numbers of springs may be utilized according to particular needs and styles of footwear, such as whether the same is intended for running, walking, or sporting activities such as tennis or racquetball. [0066]
Regarding such applications of usage, it is important to distinguish the present invention from prior art assemblies wherein “spring-assisted” sneakers and the like are taught to enhance jumping or other athletic performance. Rather than producing a trampoline-type effect, it is the purpose of the present invention to absorb and dissipate forces for the purpose of injury prevention and user safety. As such, it should be noted that, unlike certain assemblies disclosed in the prior art, the present system meets all rules and regulations of all major sports, rendering the same available for usage in any physical activity. [0067]
In preferred modes of manufacture, conical spring members are produced in a thickness of a range of one-sixteenth inch to three-quarter inch. However, other thicknesses of springs may be utilized if desirable. Furthermore, it should be noted that non-cylindrical springs, such as ribbon-shaped springs or bell-shaped springs, may also be encapsulated within polymeric materials to provide additional embodiments for the absorption and dissipation of impact forces. [0068]
In all such cases, the springs are manufactured in a variety of previously-determined sizes, functioning to render the springs effective for multiple previously-determined sporting events and hazardous activities. Thus, the assembly may be utilized for protective devices in activities such as diving, swimming, ice hockey, roller hockey, roller skating, skateboarding, field hockey, soccer, lacrosse, football, arena football, gymnastics, baseball, auto racing, motorcycle racing, cycling, and track and field events. [0069]
It is imperative to note that the springs of the present invention may be tailored to absorb and dissipate foreseeable forces of humans and objects coming in contact with the assembly. As such, the coiled springs allow for far greater adaptability to particular needs than traditional pads constructed of foam and the like. [0070]
Regarding the precise construction of the present invention, the springs may manufactured of polymeric materials, such as a durable plastic to provide strength for the assembly at inexpensive cost of manufacture. [0071]
Alternatively, the springs may be manufactured of metal materials, such as steel, if desired by the manufacturer. Importantly, the spring could even be manufactured of titanium, providing durability at sharply reduced weight and costs. [0072]
It is intended that the spring width also be variable according to particular needs, such as of a width of a range of one-sixteenth inch to one half inch. In all instances, the conical apertures will vary in size in accordance to the respective spring size, constantly allowing for a secure fit for each conical spring. [0073]
Moreover, the spring assembly may be manufactured in a variety of previously-determined sizes, functioning to render the spring assembly effective for multiple previously determined sporting events and hazardous activities. In any such instance, the presence of the springs within the padding or wall will significantly reduce the quantity of padding material needed, thus reducing weight and manufacturing costs. [0074]
With regards to all descriptions and graphics, while the present invention has been illustrated and described as embodied, it is not intended to be limited to the details shown herein, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated, and in its operation, can be made by those skilled in the art without departing in any way from the spirit of the invention. [0075]
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can readily adapt it for various applications without omitting features that, from the standpoint of prior art, constitute essential characteristics of the generic or specific aspects of this invention. What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims. [0076]
