ES2205973B1 - MECHANISM FOR ROTATING SHOE ON A GROUND PARALLEL FLAT THAT REMAINS FIXED. - Google Patents

Abstract

The present invention concerns a shoe mechanism, usually of a sports type, in which the part that houses the foot can rotate in a substantially parallel plane with respect to the sole thereof, which remains fixed to the ground by means of studs or nails, when it asks for an effort in the direction of rotation, then automatically returning to its resting position when the solicitation ceases, designed primarily for sports that require asymmetric efforts such as golf.

Description

Rotating shoe mechanism in one plane parallel to the sole that remains fixed.

Object of the invention

The present invention aims at a shoe mechanism, usually sports type, in which the part that houses the foot can rotate in a plane substantially parallel to the sole of the same, which remains fixed to the ground by tacos or nails, when an effort is requested in the direction of rotation, then automatically returning to its resting position when the solicitation ceases.

Background of the invention

Sports medicine experts have described how in asymmetric sports in terms of performing efforts, such as golf or tennis, injuries may occur due to repeated performance of unusual movements to that too much energy is applied and that, especially in the case of beginners, are accompanied by defective movements.

In these cases, the symptoms appear progressive and a few days of rest or the intervention of A masseuse to make them disappear.

However these overload injuries, which they usually fundamentally affect your back and your muscles, they can prevent the practice of sport for days, which professionals can assume significant economic costs and prestige and non-professionals, simply suspend the Practice your favorite sport.

In the practice of golf, low back pain is typical for the torsion and effort that this area suffers, because the stretching, being an asymmetrical sport, is always performed to the same side by overloading in this asymmetric manner the bone and muscle structures of this area.

If you observe the movements of the different body parts during the execution of the golf course called "swing", it is seen that initially the body is with the profile oriented in the direction of exit of the ball, while at finish the coup and as a result of the enormous inertia produced by the abrupt movement of the body and that the soles of golf shoes are provided with studs or nails, the leg that is towards the side where the ball comes out is in a position twisted, which can cause overloads before mentioned.

To avoid these harmful effects is for that the present invention has been conceived.

Description of the invention

The object of the invention is a mechanism for shoe, usually for sports use, which has the characteristic essential that the foot housing can rotate in a plane substantially parallel to that defined by the sole thereof, around an axis located approximately in the central third the shoe length and toward the center of its width, that is to say low the arch that forms the sole of the foot thus allowing when the corresponding leg is turned around itself, the accommodation of the foot rotates in solidarity with her, while the sole, which can be attached to the ground by means of studs or nails, remains motionless with respect to the ground.

Before continuing with the description we will define, for clarity of it, the adjectives that are will use to indicate positions. Previous indicates towards the part front of the human body, while posterior indicates the rear Upper indicates closer to the sole of the foot, while which lower indicates farther from the sole of the foot. Outside indicates furthest from the middle plane of the human body while interior indicates closer to the middle plane of the human body, which is the plane that divides it into two externally equal parts. How these indications of relative positions apply to the mechanism for spinning shoes, it is understood that this must be shoes in the corresponding foot and under these conditions the Spatial position of the human body.

The rotation of the foot housing with respect to the Fixed sole is produced starting from the position in which the shoe and the fixed sole overlap exactly, in which the shoe is "closed", in a sense such that the tip of the foot moves away from the middle plane of the human body, while the heel it approaches this plane and this direction of rotation is independent of if the shoe is left or right, as long as footwear goes on the corresponding foot. The maximum expected angle of rotation has a 90 ° value with respect to the closed position.

This turn only occurs as a result of the application to the set of a torque that exceeds a value determined, since it must overcome the resistance of a spring that tends to keep the shoe in its closed position, that is without angular displacement Therefore the shoe does not rotate while walk and you need to make an intense torque, such as occurs when executing a swing swing in golf practice, so that angular displacement occurs.

The opposite moment to the turn that the spring is adjustable within certain limits by some mechanism like a screw. The spring, on the other hand, makes the shoe recover and hold the closed position when the torque

The set is provided with a stop that prevents turning of the shoe in the opposite direction to the one described above, that is, bringing the toe towards the middle plane and moving the heel of said plane, from the closed position, so that the action of the spring or the person who wears it, cannot produce the aforementioned turn, also contributing this ceiling to solidity and consistency to the whole.

Leaving aside the part of the shoe that forms the foot housing, which can be made of any material common in shoes, such as leather, plastic, canvas, rubber, etc., the mechanism that allows the rotation is made of a material, such as the Teflon, which allows easy mutual sliding while wears little and has the other resistance qualities, impermeability, durability etc. that could be enforceable to a shoe sole.

Logically the shoe meets the characteristics of adequate weight and flexibility so as not to differentiate from another shoe that forms the pair, which will normally be a shoe of the same external form but that will not be rotating but a shoe common sport, so that the user can walk through the sports field without any problem.

The swivel shoe can be made for the foot left or right, the first for right-handed and the second for lefties. The other shoe that forms the pair is common but With the same form and measures. Naturally there is no inconvenience one in which both shoes of a pair are of the rotating type, although the invention is directed to solve the problems that occur in Asymmetric sports, which consequently only require one.

The object of the present invention is achieved with a swivel shoe as claimed by the Claim one.

Description of a preferred embodiment of the invention

It is a shoe mechanism, usually for sports use, to be used only on the foot that must withstand torsion, for example, in golf the left for right-handed or right-handed for the left-handed, being the other shoe of the pair equally but without the features of the invention nor relationship with this.

This description will be limited to a mechanism. for shoe of the left foot, being the one corresponding to the foot symmetric right with respect to the average plane that has been cited, and therefore it will not be described.

The mechanism that allows the shoe to turn 1 It consists of six structural parts and seven axes or bolts of pivoting between them and a spiral tension spring adjustable by screw.

The structural pieces are: the bottom sole 2 which can carry tacos or nails and is further away from the floor of the foot, the bottom 4 and top 5, the first located more near the sole of the foot than the bottom sole 2 but less close than the second, the bottom 6 and top 7 heels, the first one away from the sole of the foot than the second and both closer to the foot than the bottom sole 2 and finally the top sole 8 which is the piece closest to the sole of the foot.

All these pieces are linked together by means of turning mechanisms as follows:

to)

the bottom sole 2 can rotate with respect to the bottom toe 4, to the bottom heel 6 and to the upper sole 8.

b)

the bottom toe 4 can rotate, in addition to the above, with respect to the toe top 5.

C)

bottom heel 6 can rotate, in addition to what is said in a), with respect to the heel top 7.

d)

top toe 5 can rotate, in addition to what is indicated in point b), with respect to the upper sole 8.

and)

the upper heel 7 may rotate, in addition to what is indicated in point c), with respect to the upper sole 8.

F)

the upper sole You can turn as mentioned in sections a), d) and and).

The shoe is composed, in addition to the part that pick up the foot that has no differential feature with respect to a common shoe that is not subject to claim, of mechanism 1 formed by a set of soles and heels, of several pivots of rotation of these soles and heels to each other, of a spring and a spring regulating screw that allow rotation of the foot housing with respect to the ground, when exercised a torque greater than a certain value, while the part of the sole that contacts the ground cannot turn on him for being linked to it by means of tacos or nails.

The bottom sole 2, which occupies the most position away from the sole of the foot, and can be provided with studs, nails or other elements of grip to the ground by its lower face (no represented), by its upper face is provided in its third center of a shoulder 21 whose width is that of sole 2 and whose thickness is equal to the sum of the thicknesses of the two pieces of toe 4, 5 or the sum of the thicknesses of the two pieces of heel 6, 7, both being equal. Said highlight 21 has two U-shaped recesses 22, 23, with two straight sides oriented substantially perpendicular to the longitudinal dimension of the shoe and they reach the outer edge of the shoe and on the side opposite have a semicircular area, the upper U being 23 plus smaller than the lower U 22. In the center of the aforementioned areas semicircular, which is the same because they are concentric, there is a drill 30 to insert a pivot pivot.

The front part of the shoulder 21 is limited by two arched surfaces 25, 26. Surface 25 is defined by an arc of circumference and that extends throughout the width of the sole 2, with a radius equivalent to the distance between pivot point 43 of lower toe 4, and the edge 41 of this toe 4 that is close to said arc 25 and that fits over it, so that this piece can rotate without impediment, and for a height that from the inside of the mechanism 1 until the intersection with arc 26 is equivalent to the sum of the heights of the bottom 4 and top 5 toes and a from that intersection is equal to that of the bottom toe Four.

The arched surface 26 is defined by a arc that extends from the intersection with the surface arched 25 to the outside of mechanism 1 and by a uniform height and equal to that of the top toe 5 and located at same level as said upper toe 5, to allow during the turning movement of the upper toe 5, the edge 51 can move freely without bumping into shoulder 21.

The back of shoulder 21 is limited by two arched surfaces 27, 28. Surface 28 is defined by an arc of circumference and that extends throughout the width of the sole 2, with a radius equivalent to the distance between pivot point 62 of lower heel 6, and the edge 61 of this heel 6 that is close to said arch 28 and that adjusts on it, so that this piece can rotate without impediment, and for a height that from the outside of the mechanism 1 until the intersection with arc 27 is equivalent to the sum of the heights of the bottom 6 and top 7 heels and a from that intersection is equal to that of the lower heel 6.

The arched surface 27 is defined by a arc that extends from the intersection with the surface arched 25 to the inside of mechanism 1 and by a uniform height and equal to that of upper heel 7 and located at the same  level than said upper heel 7, to allow during the spinning movement of the upper heel 7, the edge 71 can move freely without hitting the shoulder 21.

The bottom sole 2, in addition to the turning point central 30, which is the true axis of the rotation of the mechanism for shoe, has two other holes to insert two pivots: one very close to the toe 31 and another very close to the rear end heel 29.

The mechanism of the rotating shoe 1 also has two toe pieces 4, 5 that substantially occupy the third front of the shoe, and are placed intermediate between the soles lower 2 and upper 8, which are superimposable exactly to each other and in the same way as the toe of the shoe. They both have form of a surface limited by three arches and of uniform thickness, rounded the intersection of the arches that are cut in the front end of the shoe (front toe) and both have two holes 42, 43 and 52, 53 each to insert a pivot pivot. The arc that limits each toe piece 4, 5 that is closest to the central part of the shoe 41, 51 respectively, has approximately the same radius as the arch of the central shoulder 21 closer to the middle plane 25, and as the sum of the thicknesses of both toes 4, 5 is equal to that of said shoulder 21 fit each other when the shoe is closed.

The bottom toe 4 is joined by a pivot that crosses the hole 43 located in its front part and the bore 31 of the bottom sole 2, which allows the rotation of a piece with respect to another. Also the bottom toe 4 is attached by means of a pivot that crosses the hole 42, located in its part rear, and the hole 52 of the upper toe 5 allowing the turn of one with respect to the other. Similarly, the toe upper 5 is connected by a pivot that crosses the hole 53 located in its front and the hole 85 of the sole upper 8 allowing the rotation of one with respect to the other.

The mechanism of the rotating shoe 1 also has two pieces of heel 6, 7 that occupy substantially the third back of the shoe, and are placed intermediate between the soles lower 2 and upper 8, which are superimposable exactly to each other and in the same way as the heel of the shoe having a U shape substantially. The two pieces 6, 7 have a uniform thickness, and both have two holes each 62, 63 and 72, 73, respectively, to insert pivots. The arc that limits each heel piece 6, 7 that is closest to the central part of the shoe 61, 71 respectively, has approximately the same radius that the arch of the central shoulder 28 furthest from the middle plane, and as the sum of its thicknesses is equal to that of said highlight 21 it adjust each other when the shoe is closed.

The lower heel 6 is joined by a pivot which crosses the hole 62 located at its rear and the hole 29 of the bottom sole 2, which allows the rotation of a piece with respect to another. Also the bottom heel 6 is attached by means of a pivot that crosses the hole 63, located in its part anterior, and the hole 73 of the upper heel 7 allowing the rotation of one with respect to the other. Similarly, the upper heel 7 it is connected by a pivot that crosses the hole 72 located on its back and the hole 85 of the upper sole 8, allowing the rotation of one with respect to the other.

The rotating shoe mechanism 1 also has an upper sole 8 whose outer profile is exactly the same and therefore completely superimposable to that of the lower sole 2 (see Fig. 2), as well as partially to the lower toes 4 and upper 5 and lower heels 6 and upper 7. In its third central, according to its longitudinal dimension, has a protrusion formed by two concentric circles 81, 82 and the bottom 81 greater than the upper 82, having circles 81 and 82 forming the highlight in its center point and the upper sole 8 a through hole 83 that allows the introduction of a pivot. The thickness and diameter of both circles is such that it allows its insertion through the part openings of the U-shaped recesses 22, 23 existing in the central highlight 21 of the bottom sole 2 and the diameter of the circle smaller 82 is equal to or slightly lower than that of semicircle 23 which forms the smaller U, while the diameter of the larger circle 81 is smaller than that of semicircle 22 of the U major, in order that a spiral spring 34 can be fitted between them.

The upper sole 8 is jointly and severally attached to the part of the shoe that forms the foot housing. The sole upper 8 has two holes 84, 85 on its back and previous respectively, which allow the introduction of pivots that join this piece with the upper heel 7 and the toe top 5, which also have the corresponding holes 72 and 53 for said pivots, so that they can rotate each other.

Inserted inside the shoulder piece 21 of the lower sole 2, substantially occupying the periphery of the arch 22 and surrounding the larger circle 81 of the upper sole 8 is a spiral spring 34, whose ends are joined by one side to a screw 33 of graduation of the tension thereof and on the other side to a point on the periphery of the major circle 81 of the upper sole 8, so that when the mechanism is closed the spring 34 should turn less around the circle 81 and be found in its most relaxed position, although exercising certain turning moment, while when the mechanism opens the spring 34 is in its most forced position, because it has to circle around circle 81, thus exercising a greater moment than in the previous case. The tension of the spring is adjustable by means of thyme 33, which can be moved by rotation through threaded hole 35 that exists in shoulder 21. When the screw is inserted into the shoulder 21, the spring produces a lower turning moment than when the screw is extract out.

Being part of the upper sole 8 exists in its outer part, furthest from the middle plane, a stop 86 whose height, that is the dimension perpendicular to the plane of said sole 8, is substantially equal to the sum of thicknesses of the two soles 2, 8 and the two toes 4, 5, whose purpose is to get the mechanism 1 in closed position have all its elements structural superimposed exactly and that prevents tension of spring 34 can rotate the assembly counterclockwise permitted.

The operation of mechanism 1 is the next:

(to)

starting from the position in which the mechanism for swivel shoe 1 is closed, in which all soles, toes and heels 2, 4, 5, 6, 7 and 8 they are in a situation of perfect overlap with all corresponding edges in coincidence, stop 86 is located glued to the outer edges of the bottom sole 2 and the lower toes 4 and upper 5 and spiral spring 34 in its more relaxed position, that is to say deployed and located next to the edge 22, when a torque is applied to the mechanism in the direction indicated by arrow A;

(b)

the upper sole 8 solidarity with the foot housing begins to rotate in the direction indicated by arrow A, bearing in mind that the drawing presents a bottom view, around the pivot that crosses the holes 83 and 30;

(C)

the toe top 5 starts a mixed spinning movement around the pivots running through holes 53 and 52 and displacement indicated by arrow A;

(d)

the upper heel 7 also initiates a mixed movement of rotation around the pivots that pass through holes 72 and 73 and of displacement indicated by arrow A;

(and)

when the turn and the displacement of the upper toe 5 reaches a certain point a turning moment appears on the lower toe 4, which begins to rotate around the pivots located in their through holes 42 and 43 and to move in a mixed movement following the direction of arrow A. This movement continues well until the torque on mechanism 1 or until the set reaches its maximum distension position, which occurs when the pivots that pass through holes 42, 43, 52 and 53 are find on a straight line, whichever comes first;

(F)

simultaneously to the above, when the rotation and displacement of the upper heel 7 reaches a certain point, a turning moment appears on the heel bottom 6, which begins to rotate around the pivots located in its through holes 62 and 63 and to move in a motion mixed following the direction of arrow A. This movement continues well until the torque on mechanism 1 or ceases well until the set reaches its maximum position bloating, which occurs when the pivots that cross the holes 62, 63, 72 and 73 are on a straight line, what Let it happen first. The mechanism 1 is designed so that this last position is reached simultaneously by the toes 4 and 5 on the one hand and on heels 6 and 7 on the other.

(g)

at the same time the spiral spring 34 is closing as a result of turning movement in the A direction, exerting a turning moment on the mechanism 1 that opposes the opening thereof;

(h)

the process of Closing of mechanism 1 takes place when the timing of torsion and by the action of the spiral spring 34 which causes the upper sole 8, toes 4 and 5 and heels 6 and 7 effect movements with respect to the lower sole 2 opposite to those described previously and represented by arrows C until the mechanism reaches its resting or closed position, which occurs when the stop 86, linked to the upper sole 8, encounters the outer part of the lower sole 2.
