Definitions
- the invention relates to shoes, providing energy storage by a spring, bending (contracting) under the influence of the mass of the user, and the use of this energy when releasing the spring to push the user's legs; these shoes can be used for everyday wear, as sports shoes, including shoes for running, jumping, skiing, ice skating, roller skating, etc., as well as devices used with regular shoes, to provide energy storage.
- This removable device includes:
- an arcuate plate spring intended for periodic elastic deformation (compression, bending, approaching the ends of the spring to each other) under the influence of gravitational forces applied to it from the mass of the user with the accumulation of part of this energy and release (extension, distancing of the ends of the spring from a friend) when removing the load from the user's mass on this spring (for example, when transferring gravity to the other leg) with the release of accumulated energy and applying it to the user's leg in the form of a push forward and up x;
- the lower shoulder of the spring is equipped with a support element for interacting with the support surface;
- pivot-lever mechanism located on the concave side of the arcuate spring, fixed on the user's leg, mainly on his knee, and including:
- the central support (rigid vertical element), fixed on the knee of the user using the knee strap, and in the upper part through a hinged mounting device connected to the upper part of the leaf spring, and in the lower part, rigidly connected to the base, which is located in relation to the central support at an angle of 90 °;
- connecting rod-articulated connection between the front of the base and the area of the lower shoulder of the spring, somewhat remote (about 1/3) from its end with the supporting element, the connecting rod-articulated connection includes a connecting bracket interacting with the spring;
- the force created by the user (runner) is transmitted to the spring in two ways: one way - through the linkage mechanism and the upper mounting device to the upper end of the spring, and from it through the supporting element to the supporting surface, the second way - through the connecting bracket to the bottom of the leaf spring and from there through the support element also onto the support surface.
- the disadvantage of this device is the inconvenience of operation, the inability to use in everyday life; moving is possible only in races or in jogging.
- a number of technical shortcomings were revealed in this device, including the unreliable fastening of the foot base: with a large weight of the user, even with the support device, it can be distorted, etc.
- a jumping device is also known as an improvement on the previously described design, developed by Tae-Hyuk Noop and patented in a number of countries (see US Pat. No. 6,840,893).
- a known device includes:
- an arcuate plate spring designed for periodic elastic deformation (compression, bending, approaching the ends of the spring to each other) under the influence of gravitational forces applied to it from the mass of the user with the accumulation of part of this energy and release (extension, separation of the ends of the spring from a friend) when removing the load from the user's mass on this spring (for example, when transferring gravity to the other leg) with the release of accumulated energy and applying it to the user's leg in the form of a push forward and up x;
- the lower spring arm is equipped with a wear-resistant support element for interaction with the support surface;
- a base for placing the user's foot platform, support
- a “shell” that provides reliable retention of the user's foot on the platform, that is, performing the function of the top of the shoe and / or fixing elements
- the principle of operation of this device is similar to the principle of operation of the device according to patent US 6719671 and is based on the bending of the spring under the action of potential and kinetic energy from the mass of the user, during which the energy is accumulated, with the subsequent release of the spring with the simultaneous release of the stored energy and the direction of this energy to move user forward and up.
- a disadvantage of the described device is the complexity of the design, the inconvenience of operation, the inability to use in everyday life. Moving with such a device requires considerable effort, special skills and a well-developed coordination system. In addition, moving with such devices is only possible in races or running. Moving in steps is not possible.
- the specified shoes with the accumulation of energy caused by elastic deformation, in the form of shoes, shoes, etc., includes:
- fastening devices for fixing the position of the user's foot on a given sole, moreover, these fastening devices are connected to this sole and this back;
- leaf spring is elastically deformed from the initial state to the compressed state
- the amount of load compressing the spring in the form of the sole and back is determined not only by the weight of the user, but also by the effort of his leg muscles.
- the load gravitational force from the mass of the user and energy from the work of muscles
- the load is transmitted mainly to the lower shoulder of the spring (impact on the sole of the foot of the user) or to the lower part of the upper shoulder of the spring (impact on the elastic back, for example, the heel of the user), as a result of which the gravitational effect on the spring in this shoe is not effective enough.
- a closer prototype for the spring unit may be the above-described design of US Pat. No. 6,840,893, including
- a device for transmitting gravitational action to the spring mounted on the user's leg, and including a base with a sheath for placing the foot, rigid vertical link connected to the top of the spring), while not the foot base, not in contact with the supporting surface, rigidly fixed perpendicular to the vertical rod, the length of the vertical rod is always less than the distance between the upper and lower ends of the spring, even when fully loaded (bending, compression).
- the disadvantage of the prototype device is the inability to move in it in a simple step, you can only jump in it. This is explained by the fact that the user always has only one fulcrum - the lower end of the spring.
- the objective of the present invention is to increase the efficiency of using gravitational effects on the spring, which accumulates energy when it is bent (compressed) and releases stored energy to further push the user's legs by optimizing the transfer of load to the spring and allowing energy to be released at a given point in time, and it also facilitates the process of movement due to the predominant use of the traditional nature of rolling the feet from heel to toe.
- Another objective is to create a simple adaptation to ordinary shoes in the form of a spring unit, which, in addition to solving the above problems, can be moved in steps by using two support points (for example, the lower end of the spring and the sole of ordinary shoes).

- the heel with a compressed spring can adjoin the sole of the shoe.
- the sole in the free state of the spring can adjoin to the heel and be associated with it.
- the spring can be of various shapes, for example, have a simple arcuate (bow-shaped) shape, an arc shape with an additional bend, for example, under the user's heel, the shape of half an ellipse (flattened shape), etc.
- a spring can have a different cross-sectional shape, for example, a seriform cross-section, a cross section in the form of an elongated isosceles triangle, an elongated ellipse, a rectangle, a U-shaped element, etc.
- the cross and longitudinal section of the spring can be constant or variable.
- the material of the spring can be constant or variable in length, width and thickness.

- the bending spring represents the main elements of the shoe, for example, the back or part of the back, the side elements of the shoe, the heel, etc.
- the sole in most cases is a traditional sole, which is not a spring (although the sole in some embodiments may also be an element of the lower part of the spring) and, at the same time, the heel (part of the spring) is, along with the sole, a support for interacting with the surface.
- the heel is not directly connected to the sole; however, with a compressed spring, the user's heel together with the sole can rest on the lower part of the spring — the heel.
- the lower support portion of the spring may be in the form of a heel aligned with the sole or only in the form of the sole. In one of the options, the heel during the deformation of the spring can approach the outside of the sole and adjoin to it.
- the peculiarity of the spring block which can be used as an attachment worn on ordinary shoes, is that the user gets the opportunity to accumulate the energy of the bending spring, the lower part of which is in most cases a heel (supporting part), and the upper part the spring is loaded with a gravitational load from the user's body mass, and use this energy to facilitate movement.
- the displacement, as well as in the claimed gravitational shoes can occur in the traditional way due to that in the process of moving is involved not only the supporting end of the spring, but also the sole of the user's shoe.
- the principle of energy storage and release in the inventive shoes and in the spring unit is similar to the principle of removable devices to facilitate jumping and running: the arcuate spring is deformed by the mass of the user, accumulating energy, and then, when released, transfers energy to the user, pushing his leg forward and up.
- the user's foot is not involved in the process of moving, it is passively standing on the base (platform), and this base does not even touch the supporting surface (ground).

- FIG. 18g is an elongated rectangle with a slightly concave base;
- FIG. 18e is a cross-section of three springs covering the leg.
- the cross section of the spring may be constant in length, or may vary.
- a spring located on the back of the leg has a C-shaped section in the upper part (partially covers, bends around the leg), and in the lower part that passes into the conical heel, has the shape of a circle.
- Two lateral springs with a rectangular cross-section can be connected and form a common rectangular or ser-C-shaped cross-section in the lower part of the spring.
- the elastic characteristics of the spring can be constant or variable along the length and thickness of the spring, for example, the material of the heel 2 can be more rigid than the rest of the spring.
- the shape of the spring 1 may be different:
- spring is not limited to one spring. There may be several. The upper part of the spring 1 can be located on the back of the shoe, especially if only one spring is used. In another embodiment, several (two or more) springs cover the heel of the user's leg from the sides (Fig. 4a, 46, 5, 6a, 66, 10, 1 16, 12c, 12g, 12d, 12e) or pass simultaneously from the back of the leg and from the sides (7a, 76).
- springs can be interconnected, for example, in the area of the supporting element (heel or sole).
- each of the springs may have one upper part and two or more lower parts, and vice versa.
- the above illustrations do not exhaust all possible options, both in terms of the number of springs used and their location.
- bending is most often provided primarily by acting on the upper part of the spring 1 while supporting the heel 2 on a supporting surface, for example, ground.
- the spring can be equipped with a special protrusion under the heel, although the heel can also rest on a smoothly curved arc (without protrusions).
- the height of the heel 2, which is the lower part of the bending spring 1, may be different.
- the heel In women’s shoes, the heel can be quite high, for example 5-7 cm or more, the most clearly illustrated heel is shown in FIG. 12a, b, c, d and in FIG. 19, 20.
- the heel height may be less, for example 1-3 cm (Fig. 9, 10).
- the heel which, as in any other shoe, is a support for the user's heel, may not protrude beyond the sole level (Fig. 8a, b, c).
- the lower end 2 of the spring 1 partially covers the heel (acts as a supporting element under the heel, that is, it is a kind of heel) and is connected with the sole 3.
- the upper part of such a spring can be loaded from the side of the cuff 5 and / or cover 6 and / or covering tape 7. While Hi> H 2 , the leg is suspended, there is a gap between the sole 3 and the user's foot, when bending the spring, the leg rests on the sole 3 and the lower edge of the spring 1.
- a shoe option with a folding (approaching the sole until the sole is completely abutted) heel 2 is also offered.
- the heel 2 gradually bends and tends to join the sole 3 (Fig. 2a, 26).
- the sole in turn can approach the heel.
- the spring in the lower part can be divided into two spring elements located at an angle to each other: the heel and the sole (Fig. 15 and 16).
- Such an implementation will allow, firstly, to increase the efficiency of energy storage (two springs), and secondly, to prevent its irrational use due to the transfer of energy from the heel to the sole at the beginning of the heel detachment from the support (eliminating the need for a latch), thirdly, to accelerate the rolling of the legs from heel to toe.
- the space between the heel and the sole of the it is filled with easily deformable material, for example, porous, which eliminates the ingress of foreign bodies (pebbles, dirt, etc.) between the springs.
- FIG. 17 shows an embodiment of a shoe (or spring unit) in which the springs around the leg are connected to the sole, which is also a spring. This will facilitate and accelerate the process of rolling the feet from heel to toe.
- a variant is possible when the heel, combined or connected with the sole, plays the role of the spring support element, or the spring support element represents all or part of the sole (Fig. 13a, b).
- its length may correspond to or exceed the length of the sole of the user's feet, and the movement is carried out by first lowering the legs onto the toe (at the end of the spring 1).
- the upper 4 of the shoe in addition to the required elements, may include an outer shell covering the spring 1, or adjacent to the spring, or passing under the spring and allowing its periodic bending.
- This shell can be made corrugated or consisting of separate annular elements adjacent to each other or located on each other.
- the sheath can partially or fully cover the leg.
- the top 4 of the shoe may include an interior directly adjacent to the foot (lining).
- This inner part may be substantially unconnected with spring 1 and may not undergo bending deformation, in which case the requirements for the material are common. If the inner part is connected with the upper part of the spring 1, then the material and / or design of the inner part must provide the possibility of its deformation during compression of the spring.
- Sole 3 can correspond to the shape of the sole of ordinary shoes and provide a comfortable arrangement of the foot, protection of the foot from mechanical influences.
- the sole (its lower surface), as in other types of shoes, should be sufficiently durable.
- the sole 3 can be connected with the lower part of the spring 1 to provide additional transmission of compressive forces from the foot to the spring.
- the connection can be made, for example, in the form of a swivel, which allows the sole 3 to be inclined with the forefoot to the abutment surface.
- the sole 3 in the initial position, the sole 3 is horizontal, and when walking periodically tilts the toe down to support the legs, rolling from heel to toe and pushing away.
- the foot may immediately adjoin the sole 3 (without clearance), not resting on the ground. With the beginning of the phase of support on the ground, gravitational forces are distributed and act on the spring in its upper part through the cuff and in its lower part by the heel through the back of the sole or only on the lower part of the spring (Fig. 16, 1c).
- the leg in the initial position does not adjoin the sole 3, not resting on the ground (supporting surface), a gap remains between them (Fig. 2a, b, 8a, b, c, 126, d), the following ratio Hi> H is maintained . > H 2 , where H is the distance from the top of the spring (the point of suspension of the foot) to the place of attachment of the sole.
- H is the distance from the top of the spring (the point of suspension of the foot) to the place of attachment of the sole.
- the spring 1 can be equipped with a latch 10, clamping the spring 1 in a compressed position and releasing it at a given moment, for example, when pushing the user's legs away from the supporting surface (the next step). This is necessary so that the stored energy is not wasted when moving the leg from the heel to the toe, because if the spring comes off the support for a time longer than the spring returns to its original state, the energy will be lost.
- the embodiment of the latch 10 and means for releasing the latch from the engagement may be any known in the art. So in FIGS. 1 1a and 1 16, one of the possible mechanical devices is shown: the latch in the form of a hook 10 engages with the spring 1 and is disengaged when the foot acts on the link 1 1.
- the embodiments of the latch 10 shown in the figures do not in any way exhaust the possible embodiments.
- the latch 10 may be magnetic or electronic based.
- the main condition is that the moment of fixation should coincide with the maximum deformation of the spring, and the release should coincide with the moment of repulsion of the user's leg from the supporting surface.
- FIG. 12 g presents women's shoes, the sole of which is connected with a spring, while the back of the sole extends beyond the heel (lower part of the spring) and serves as an additional support for the heel. Similar constructions are shown in FIG. 12e and 12f. These options can most effectively be used as ballet shoes.
- the spring block (Fig. 14, 22) can be used as an adaptation to ordinary shoes, accumulating gravitational energy, providing the ability to move both by running (jumping) and by a step with rolling the legs from the heel to the toe.
- Spring block - a fixture in design mainly corresponds to the spring block used in the claimed gravity shoes. It includes at least one spring 1 and a spring attachment device in the form of the cuff 5 described above, covering the calf of the wearer, or a soft inelastic (non-stretching) element supporting the leg 7, by means of which a soft suspension of the user's leg relative to the upper part of the spring is provided 1 and transmission to the spring 1 of gravitational impact.
- the ratio of the sizes between the ends of the spring 1 in the free (unloaded) state Hi and the distance from the suspension point to the bottom point of the sole 3 of ordinary shoes ⁇ 2 is similar to the above: Hi> ⁇ 2 .
- the form of execution of the spring block as a device is similar to the spring block of gravitational shoes.
- the inventive gravity shoes are used as follows.
- the user wears shoes and fixes, if necessary, the position of the leg with special fastening devices, for example, fixes the cuff 5 and the sole 3 with straps.
- the user lifts one leg while continuing to lean on the other.
- the spring 1 is released, while Hi> H 2 , the user's leg hangs on the top of the spring 1: on the cuff 5, in the cover 6 or on the tape 7.
- this leg first touches the supporting surface protruding supporting element of the spring, for example, a heel.
- the user transfers part of his mass to this leg, compressing the spring 1.
- the distance between the ends of the spring 1 becomes equal to or approaches the distance from the suspension point to the lower point of the user's foot ⁇ 2 . Compressed spring 1 accumulates energy.
- the user's leg With further movement, the user's leg, as usual, rolls from heel to toe to push the forefoot away from the support. If the characteristics of the spring are selected in such a way that it straightens for a period of time exceeding the time for rolling, the spring energy is not lost, and at the moment the toe of the leg comes off the support, pushes the user's leg forward and up. If the spring is released quickly, then it is advisable to use additional devices - clamps 10, which ensure that the spring 1 is kept in a compressed state until it is repelled.
- the locking device 10 can be removed from the engagement by the action of the metatarsus on a special tool, for example, the rod 1 1 connected with the locking device with a curved section in the front part under the metatarsus. The length of the rod 1 1 when pressing on the protruding curved section increases and the rod pushes the hook of the latch 10 out of engagement with the spring 1.
