Definitions

  • the invention relates to footwear, which ensures accumulation of energy by means of a spring, compressive under user's body mass and usage of this energy when the spring is released to push user's foot upward.
  • the said footwear can be used in every day wearing as a sport's footwear namely as racing, jumping, skiing, sliding, rolling shoes etc. as well as a device that complements conventional shoes to provide accumulation of energy.
  • This removable device comprises:
  • the enhancement created by a user is communicated to the spring by two ways.
  • the first way provides communication through the lever mechanism and the upper fixing element on the top of the spring, then from the latter through the supporting element on the supporting surface.
  • the second one provides communication through the shackle on the lower part of the leaf spring.
  • the weak point of this device lies in inability of its exploitation, impossibility to use it in every day life.
  • the only possible way to move is jumping or racing.
  • the given device eliminates a range of technical imperfections inclusive of unreliable fixation of the base to a foot: the obliquity is still possible even having a supporting device when user's body mass becomes greater.
  • Another known device is the one, designated for jumping. It represents the advanced design described hereinabove and developed by Tea-Hyuk Hoon, patented in several countries (see patent US 6840893 ).
  • This known device includes:
  • This footwear such as shoes, boots, etc., designed with energy storage, induced by elastic deformation, includes:
  • the rate of the load compressing the spring being in the form of the outsole and the rear part is determined by the weight of the user, but also by strength of his foot muscles.
  • the load gravitational force exerted by the user's mass and the energy made by the muscles
  • the load is communicated on the lower arm of the spring (the impact on the user's foot) or on the bottom of the upper arm of the spring (the impact on the elastic rear part, for example, by the heel of the user)
  • resulting in a gravitational influence on the spring in the shoe is insufficiently effective.
  • Such displacement differs from the ordinary contact with the supporting surface when walking. First you stand on the heel, and then you're dragging the whole foot down and slide upward on the toe.
  • the disadvantage of the device - the prototype lies in inability to move a simple step when wearing such device. It allows only jump moving and this may be explained by the fact that the user always has only one point of support - the lower end of the spring.
  • the objective of the present invention is to increase the effective use of gravitational effect communicated on the spring, that accumulates energy when it is bent (compressed) and exerts the stored energy for an extra push of the user's feet by optimizing the communication of the load on the spring and allowing the release of energy at a given time, along with facilitating of displacement through the prior use of gravity character of the foot's rock-up from heel to toe.
  • Another challenge is to create a simple accessory device of the spring unit type to complement ordinary footwear, which will provide, in addition to the above-mentioned solutions, the ability to move at a footpace being supported at two points (for example, the lower end of the spring and the outsole of the regular footwear).
  • the outsole of the gravity footwear may be joined to the spring to transfer the complementary gravity load on the spring, where H1> H3 ⁇ H2, when there is no load applied to the spring and H3 means the distance between the top of the spring (the point of suspension of the leg) and the point of fixation of the sole.
  • H1 and H3 are close to H2 when the spring is compressed.
  • Spring unit may include several springs located in its back, on its sides or in the front of the shoe when the supporting element in the form of a heel is fabricated all-in-one-piece with all or several springs and the number of upper and below springs may not necessarily match.
  • the bottom rear part of the shoe when the spring is compressed may be located in the area of the user's heel.
  • the bottom rear part of the shoe when the spring is compressed may fit closely the sole.
  • the sole when the spring is free of load may fit closely to the bottom rear part of the shoe and be joined to it.
  • the spring can have various shapes, e.g., it may be bow-shaped, bow-shaped with an additional curve designed to fit the user's heel. It may have half- ellipsoidal shape (flattened) etc.
  • the spring can have various cross-sectional shapes. It can be sickle-shaped, oblong isosceles triangle shaped section, oblong ellipsoidal shaped section, rectangle, U-shaped element, etc.
  • the cross-section and the longitudinal section of the spring may be constant or variable.
  • Material his physical and technical properties of the spring may be constant or variable in length, width and thickness.
  • the spring may be partially or entirely made out of one or several materials: polymers, including polyurethanes, polycarbonates, and others, composites, elastomers, etc.
  • the upper part of a shoe includes a coat that covers the spring in its part or entirely.
  • the latter may be joined to the upper part ensuring the possibility to change the angle of the spring, e.g. by fabricating the upper part corrugated or made out in the shape of a set of coherent and extensible elements.
  • the specified objective may be met by means of another type of gravity footwear, such as a shoe, boot etc., which accumulates energy, exerted by deflection and including:
  • the spring unit comprising at least one spring of the given value of flexibility, deflecting
  • the spring is provided with a spring-lock to fix it in a compressed state and a braking device that release spring-lock fixation when it is necessary, e.g. prior to perform pushing legs away from the supporting surface.
  • the claimed gravity footwear is featured by the flexure spring which constitutes basic shoe elements, e.g. a counter or a part of the counter, side elements, the heel etc, when the sole commonly remains traditional and it is not provided with a spring (although some options may provide a sole that represents an element of the lower part of the spring) and the heel (part of the spring) represents together with the sole a support to contact the surface.
  • the flexure spring constitutes basic shoe elements, e.g. a counter or a part of the counter, side elements, the heel etc, when the sole commonly remains traditional and it is not provided with a spring (although some options may provide a sole that represents an element of the lower part of the spring) and the heel (part of the spring) represents together with the sole a support to contact the surface.
  • the heel In most fabrications the heel is directly joined to the sole. But when the spring is compressed, the user's heel along with the outsole may base upon the lower part of the spring heel.
  • Several fabrications provide the lower supporting part of the spring made out in the form of the heel fitted to the sole or in form of the sole only. One of the options provides that during deformation of the spring the heel may come closer to the outer side of the sole and even join it.
  • the main benefit of the sprig unit featured by its ability to be used as a device, which fits into an ordinary shoe, is the fact that the user gets opportunity to accumulate energy disbursed by the flexure spring, the lower part of which is in most cases a heel (supporting part) and the upper part gets gravity load of the user's mass, and to use this energy to facilitate displacement.
  • the displacement as well as it provided by the claimed footwear may occur in ordinary way by means of engagement not only of the supporting end of the spring but of the footwear sole also.
  • the principle of accumulation and release of energy in the claimed footwear and in a spring unit seems similar to the principle of removable devices for improvement of jumping and racing: the bow-shaped spring gets deformed under the user's mass, accumulating energy, and then, when it is released it transfers energy to a user, pushing his/her feet forward and upward.
  • the foot rests passively on the support that does not even contact the supporting surface.
  • Footwear and the spring unit can officinal or homemade. Therefore, they meet the criterion of "industrial applicability"
  • Figures which give the layout view of the main footwear options. Most of these Figures illustrate only the basic elements of footwear in order to facilitate understanding of the essence of the claimed objects, while the secondary (topmost of footwear, mount, etc.) are not shown; user's foot is shown in thin lines :
  • the claimed gravity footwear may appear in the form of a shoe, a boot or a high boot, a sandal etc., including as a mandatory element, at least one flexure spring of the given flexibility, deflected from the initial state to a compressed one and exerting energy on pushing user's foot when it is released or acceleration due to synergetic effect when the foot would roll from heel to toe.
  • the said spring 1 in the claimed shoe or is joined to traditional shoe elements, e.g. bottom rear part or a heel, either it is a pat thereof, either a complementary inside or outside shoe element.
  • the upper part of the spring can embrace user's foot, but at the same time it can go inside a shoe, be sewn into a shoe or be attached from the top of a shoe ( Figures 9 , 10 , 11 ).
  • the lower part of the spring is a supporting element contacting the surface that a user is going on.
  • the most embodiments of the claimed footwear the said supporting element is designed as a high heel 2 ( Figures 1-7 , 12, etc.) or a low heel 2 ( Figures 9 , 10 , 11 ).
  • a support element of spring in the form of heel and sole, and in the form of sole only are possible.
  • the claimed gravity footwear apart from the said above spring 1, includes the usual elements for the appropriate shoes: sole 3, topmost 4 etc.
  • the topmost 4 of a shoe ensures protection of the user's foot from adverse impacts fixes the position of the user's foot and provides opportunity for regular curving of spring 1 without damages to topmost elements 4.
  • the said topmost 4 includes fixing devices to fix user's foot, the topmost 4 and fixing devices are joined by the said spring 1, sole 3 and other shoe elements.
  • the said fixing devices can be stiff part of the topmost of a shoe, e.g. stiff strips etc., and/or fixing elements, e.g., belts, strips, laces, coats, Velcro, zippers etc.
  • topmost of a shoe can represent only a fixing device, e.g. wherein sandals are the embodiment of such shoe ( Figure 19 ).
  • the said topmost 4 of the shoe furnished with fixing devices apart from fixing of the user's foot and its protection against environmental impacts must provide the communication of gravity action from user's body mass on spring 1, therefore special elements are designed in the claimed footwear.

There can be a several number of such rings (not shown in Figures). There can also be other, not considered herein options of application of relatively pin or distributed gravity load to the upper part of spring 1.
  • Cuff (ring) 5 performs function of load transferring to the top of the spring from a shin, therein the user's foot hangs down in the cuff due to thickening of the shin, to the firm embracing of the shin by the cuff (clip), or due to the both, thickening and firm embracing at once.
