Abstract

A grip sole for a golf shoe has curved grip elements (12 to 15) sliding in curved guides under the main part of the sole, with the centres of curvature towards the rear of the shoe. The grip elements can be fitted with soft spikes or actual spikes and slide between two end settings braced by return springs. The main part of the sole has several curved grips from toe to the instep. Similar curved grips (16, 17) can be fitted under the heel, with the centres of curvature towards the toe.

Description

  The present invention relates to a sports shoe for a golfer having the characteristics specified in the preamble of claim 1. The golf shoe has a plastic sole that has a more or less different contour shape, with a protruding ground engaging element, in particular a swimsuit, in order to bite the ground firmly and improve the stability of the golfer, They are designed to pierce the lawn or ground deeply or shallowly. The spikes are made of steel or ceramic material, and so-called soft spikes or plastic spikes are also used. Soft spikes are compulsory on some golf courses because they are less likely to damage the golf course than spearks made from steel or ceramic materials. The spike is either firmly attached to the sole or can be replaced. In the latter case, the sole is usually provided with a threaded hole, for example, a metal threaded bushing is embedded in the sole and a spike with a matching groove on the outside is provided. It can be screwed in.

  When hitting a golf ball, especially when hitting the ball on a tee, the player's torso and waist should ideally rotate around a stable axis that should coincide with the player's spine. The player swings the golf club upward, then returns, passes forward through the ball position, and finally continues the swinging motion in the targeted direction while rotating the player's torso and waist. The movement ends with the breast and the pelvis rotated in the direction of flying the golf ball. At the end of the swing movement, the player's position must be in the desired orientation, and the waist and pelvis must be in such an orientation-although standing at the original position that crosses the end line. The end of the left foot of the user faces the ground and the inner edge of the left foot is lifted up, while the right foot turns in the aimed direction and the right footpad is on the ground. Lift up from the top. For left-handed players, the left and right foot movements are reversed, the left foot bends, and the right hip rises from the ground. When the golf ball is thrown far away, the player's body is strongly twisted, and this twist reaches the back column and strains the ligaments and joints. For this reason, golfers, especially those who exercise frequently, do not work out completely, do not work, and / or have reached a considerable age-this is true for most golfers- The limb area is subject to excessive stretch, strain, joint bone dislocation and / or pain from tension. The golf shoe known from the German patent DE 100 30 917 A1 is provided with a torsion plate with spikes on the heel, which likewise cannot prevent these effects.

  Accordingly, an object of the present invention is to provide means for reducing the tensioning and damaging effects on the player's body that are caused as a result of an unnatural movement made when a golf ball is hit.

  This object is achieved by a sports shoe having the features specified in claim 1. Further advantageous developments of the invention are the subject of the dependent claims.

  This invention will be described below only for right-handed people, but this description applies to left-handed people as well.

  When a golfer—a right-handed person—is wearing a normal shoe on the left foot that has the action of giving the necessary stability when swinging, the spike is stuck against the ground or the lawn, so the swinging motion cannot be followed. On the other hand, however, the golfer cannot raise the left foot during the swing movement and cannot point the left foot to the same swing surface as the right foot, and then the player loosens the holding with the moment of movement and moves forward. End up.

  When the sports shoes according to the present invention are used, the situation changes completely. The spikes of the sports shoes according to the present invention are similarly pierced into the ground, but the shoes are rotated at a certain angle from the starting position and are directed in the aimed direction, which is along a circular arc. Since the spike is guided, it is preferably in the shape of a circular arc or spiked on one or more movable supports which are guided and held by guiding means for guiding the spike along the arc. It is because it is provided. Therefore, the shoe can be rotated correspondingly to the spike stabbed in the ground. Even if the left shoe rotates, the stability of the golfer is not threatened because the left shoe spike is stuck in the ground during the swing movement.

This invention provides important advantages:
● Torsion of the body, waist, knee joints and ankle joints during swing movements is reduced. Even if the twist angle is reduced to some extent, this reduces the burden on the player and makes it easier. Because it is the toughest and most tense for the body and goes beyond the limits that many players cannot tolerate. Therefore, if the twist is a little lighter, the player's ligament will not be excessively stretched by the rotational motion, and there will be no excessive tension on the joint.

  ● The risk of injury, especially in the areas of the back column, ankle and knee joints, is greatly reduced. The risk of dislocation, and even the risk of dislocation of the disc, is greatly eliminated.

  -Since the weight of the golfer moves from the outer edge of the shoe to the front part during the rotational movement of the shoe, the stability of the player in the final state of the swing movement is increased.

  ● You don't feel tired when you play golf and you don't have to use your energy.

  ● Surprisingly, the accuracy of the direction of golf ball flight was improved. Although this result was not what was expected, it goes without saying that it is highly desirable that the golfer's prowess will improve and the joy of playing golf will increase.

  The plurality of spikes are individually guided by undercut arcuate grooves. These are preferably provided on a support that slides in an arcuate place. Theoretically, it is sufficient to provide the spike on one support, and in practice, it is only provided on the front part of the shoe sole. If only one support is provided, it is preferred that it be wide enough to fit in an arrangement in which one of the plurality of spikes or ground engaging elements is behind the other. On the buttock side, a spike is advantageous if it is present, but it is not always necessary for the purpose of the present invention. However, on the buttock side, it cooperates with one or a plurality of supports in the front part of the foot, and further has a common center of curvature so that the foot rotates around a predetermined rotation center. One or two supports are preferably provided as well. However, this does not mean that the positions of the centers of curvature at which the separate supports rotate are not slightly separated from each other: the centers of curvature are not separated from each other, so that the shoe is in rotational motion. It just means that it is no longer possible. The point to be considered in this regard is that the spike is not fixed so as not to move on the ground, and the ground (especially in the case of lawn) is somewhat elastic.

  As in conventional golf shoes, steel spikes, ceramic spikes or soft spikes can be used; these spirks can be securely connected to the support and can also be exchanged. The present invention is not limited in this respect, and other ground engaging elements, for example, plastic protrusions integrally formed with the support, can be used, so that when walking, as with spikes. Safety and stability are improved.

  The spike or support is preferably adapted to move forward and backward between a start start position and an end position. The spike or support and guide means are then in engagement with each other for the full length of movement with respect to each other. However, for applications where the degree of demand is not so high, for example, for practice purposes, it is not necessary to determine the starting start position and the ending position in the shoe sole of the sports shoe. As a result of the kinetic force of the swing motion, if the support should slide out of the guide means and then jump out, return the support to its original position on the guide means before the next swing movement. I have to leave. However, when the support slides out of the guiding means, the spikes that pierce the ground will in this case keep the support in their respective positions and the starting start position of the foot is marked for the next swing movement. This gives an advantage to the practice purpose.

  In normal play operations, however, it is preferred that the support is held so that it cannot be removed from the shoe by guide means.

  When the structure of the sports shoe is such that the support protrudes to the outside of the guide means by a certain length, it is preferable to provide a stopper between the support and the guide means. The length by which the support slides and protrudes from the guide means can be limited. Such a stopper can be realized, for example, by providing shoulder portions on both the guide means and the respective support bodies so that they come into contact with each other when the support bodies slide out of the guide means.

  By moving as a result of the swing motion, the support must return to the starting position. This can be done by turning the foot in the opposite direction before the player raises one foot and pulls the spike out of the ground. A further easy way is to provide a return spring for each guide means and to automatically return the support to the start position with this spring. Such a return spring is configured, for example, as a helical spring or a pneumatic spring.

  Preferably, each support is shorter than the guiding means for receiving it. This is to allow the system to slide when both ends of the guide means are closed. If one end of the guiding means is open, it is more convenient to provide a return spring, even if it is not compulsory to provide it, because the return spring is located inside the support. This is because it is adapted. One end of the return spring is fixed to one end portion of the guide means, and hits the support at the start start position, while the other end is fixed to the other end portion of the guide means. In this case, the entire length of the guide means is used for moving the support.

  It is preferred that the support does not leave the guide means or the sole completely during the rotational movement. Instead, the support must be firmly held by the guiding means and be slidably engaged even if the ankle portion bends excessively. In this respect, the guide means and the support are positively combined, and in particular, the guide means is provided with a plurality of grooves, both sides of these grooves are undercut, and a slide that supports the spike in a shape that fits this. This is done by engaging the body. Grooves and tongues, especially dovetail connections, are particularly suitable.

  It is preferred that the support protrudes from one side edge of the guide means while the stopper does not protrude from the other.

  It is preferable to use the stopper so that the support does not slide out of the guide means or the sole by using the stopper. In order to return the support to the guide means or the shoe sole, the user may push back the support with the other foot. However, it is preferable to provide a return spring, in particular a pneumatic spring.

  In the case of a shoe in which the support is adapted to slide out from one side edge of the guiding means, it is necessary to return the support completely or push it back so that it does not protrude from the side edge of the shoe. In the starting start position, the end of the support is preferably flush with the side edge of the shoe sole so that it can slide.

  While the body is rotated, the direction in which the support slides is preferably different in the region on the buttocks side compared to the region on the front part. The common center of curvature should be located between the heel of the shoe sole and the front of the foot. Preferably, the top of the foot sole should be per point.

  The support is made from a metal or plastic material. These are preferably made from a plastic material having the same characteristics as the plastic material used for the shoe sole of the shoe. And the said support body has a plasticity suitable for the plasticity of a shoe sole part especially about a softness | flexibility. In this respect, walking is facilitated. In particular, when the support is slid and the guide means is a groove in the shoe bottom that receives the slide, the function of the support is not impaired. .

  When the guide means comprises a groove in the shoe sole, and the support comprises a slide body and is received and held in the groove, the advantages of the present invention are reduced in size and the feeling of walking is also a conventional sport. This is the same as shoes. However, a plurality of arc-shaped rails or brackets may be provided in the shoe sole or in the groove, slot or similar recess of the shoe sole, and these ends are fixed to the shoe sole and slide along these rails or brackets. It is also possible to provide a slide body that supports the arcuate spike.

  When the grooves are selected as a guide for movement of the slide body, both ends of these grooves are closed. As a result, the slide body is sufficiently protected and does not crash. However, if only one end of the groove is opened, each slide body can protrude from the groove by a certain length. As a result, when the shoe is rotated by the action of a swing motion, there is an advantage that the shoe can rotate at a larger angle than when both ends of the groove are closed. Depending on the structure and arrangement of the slide body, the range of the angle is a range of an upper limit of 30 degrees or a slightly larger angle depending on the telescope configuration. Even if both ends of the groove are closed to make the rotation angle narrow, it is sufficient for the player.

  According to another preferred embodiment of the present invention, the spike support can be freely attached to and detached from a sports shoe. Thereby, the sports shoes can be selected to attach or not attach the device according to the present invention. For example, in a golf show where a golfer wants to practice a lot of hitting a golf ball on a tee at a driving range, a removable support with a spike can be attached--otherwise, in golf practice, However, when wearing conventional golf shoes, the ligaments and joints are stretched too much, but such stretching can be relieved if the apparatus according to the present invention is attached to the sports shoes. However, in a golf tournament, the device according to the invention can be removed. When the support guided by the guiding means moves along a circular arc, the axis of such movement becomes the rotational physical axis of the support. Such a rotation physical axis is suitable as a guide means or a guide means part of a support. And the said support body is mounted | worn with the shoe sole part of sports shoes in such a rotation physical axis. For example, the support can be plate-shaped and fastened to the surface of the shoe sole with a threaded bolt that acts as the shaft. A threaded bolt is screwed into the thread groove bush embedded in the shoe sole, particularly the middle foot. Another guide means, for example an undercut groove or bracket, is arranged in the toe region of the shoe sole, receives and guides the front end of the support, and is further arranged in the buttocks region of the shoe sole, the support The rear end of the body can be received and guided.

  According to another possibility, the support and the associated guiding means can be arranged in a holder, which can be detachably attached to a sports shoe, in particular its sole. For this purpose, the holder is provided with one or more clamping means, which can be attached to the sport shoe, for example by a chin sandwiching the sole from the side edge. Alternatively, the holder may be provided with receiving means, and sports shoes may be placed on the holder, and the shoes may be pressed down like a ski fastener to tighten the shoes from above, thereby locking to the fastener.

  When the support is freely detachable, a return spring may be provided to hold the center point where the support rotates.

  The sports shoes according to the present invention can be used not only for golf but also for other sports in which a swing motion is performed and balance is not achieved, for example, baseball, tennis, land hockey and kickball. The shoe of the kick ball has a stud that becomes a resistance against the rotational movement of the kick ball player, and the knee joint and the ankle joint of the player are extended when it moves violently. If such a stud is attached to the shoe of a kick ball by the means according to the present invention, the stud moves in an arc shape, the elongation acting on the joint is reduced, and the cruciate ligament, which is a typical result of overstraining by rotational movement, is obtained. Breakage can be prevented.

  In this case, the sport shoe is provided with a spring-biased release mechanism, which is provided with trigger means for allowing the stud or other engaging elements to perform an arcuate movement. .

  Some examples are illustrated in the accompanying drawings.

  The sports shoes shown in FIG. 1 to FIG. 3 are shoe soles provided with guide means comprising four arc-shaped grooves 2 to 5 on the front side and two other arc-shaped grooves 6 and 7 on the heel part. 1 and these grooves are concentric with each other, and their center points M, M5, M6 are between the front side and the buttock side and partially coincide with each other. Each of the grooves 2 to 7 is adapted to fit the slide bodies 12 to 17, and these slide bodies function as support bodies and are slightly shorter than the respective grooves. The foremost slide body 12 holds the spike 9, and each of the remaining slide bodies 13 to 17 holds two spikes 9. These spikes are all on the end side of the slide bodies 13 to 17. Has been placed. The spike 9 is received by a screw bush 10 embedded in the slide bodies 12 to 17, and is screwed into the bush by a screw portion 11.

  Although the slide bodies 12-17 are movably held in the grooves 2-7, they are not removed and are connected to the grooves by means of grooves and tongues as shown in FIG. .

  The slide bodies 12 to 17 have a start start position and a start end end position in the groove. FIG. 1 shows the start end position. In the start start position, the slide body comes into contact with the end of the groove, and in some cases, the end side of the grooves 2-7. It hits the litter spring provided in the. The angle of the sports shoes accompanying the movement of the swing of the person who swings along the path of movement of the slide bodies 12 to 17 between the start start position and the start end position is determined. In one example shown in FIG. 4, the length of movement is longer than in the example shown in FIG.

  In the example shown in FIG. 4, both ends of the grooves 2 to 7 are not closed, and only one end side is closed. The grooves 2 to 7 reach the end of the shoe sole 1, that is, reach the edge inside the foot on the front side, and reach the edge outside the foot on the heel side. At the start start position, the slide bodies 12 to 15 are located on the inner side of the shoe sole 1, while the two slide bodies 16 and 17 on the heel side are along the outer edge of the heel part at the start start position. It has become. When the swinging human body swings, the slide bodies 12 to 17 slide to some extent and protrude outward from the shoe sole 1. Then, these slide bodies can be returned to the starting start position using the other foot. Separately, it is returned by a return spring 19 as shown in FIGS.

  An arc-shaped groove 18 is provided on the upper surface of the slide body 14, which is closed to the walking surface of the shoe sole 1, but is open to the base of the groove 4. A return spring 19 having the following shape is received, and steel wires 20 and 21 are attached to both ends of the spring. A plate 22 to which one end of the steel wire 21 is fixed is fixed to the end of the slide body 14, and this protrudes outward from the groove 4. The plate 23 to which one end of the other steel wire 20 is fixed is attached to the other end of the groove 4. Since the return spring 19 is not the length of the entire length of the slide body 14, the spring is not soiled with soil. Tension is applied to the return spring when the slide body 14 jumps out of the groove 4 as a result of the swing motion by the user's body, and the slide body 14 is automatically returned when the shoe is pulled up by the user. To.

  The other groove 26 in the slide body 16 concentric with the arc-shaped groove 18 is open at one end in addition to the groove 18 and closed at the other end, thereby forming a stopper 25. When 16 is pushed out of the groove 16, it finally hits the stopper 24, and this stopper 24 is formed by a protrusion protruding into the groove 6 from the shoe sole.

  In the embodiment shown in FIG. 7, a holder 27 is rotatably attached along the bottom of the shoe sole 1. This is performed by a screw bush embedded in a region between the middle foot portion and the heel portion in the shoe sole portion, and a screw bolt 28 is screwed into the bush via a washer 29 to attach the holder 27 to the shoe sole portion. The holder can be rotated about the screw bolt 28 as a rotation center. The holder 27 is composed of two arms 27a and 27b. These arms extend along the length of the shoe sole 1 and support the cross members 30, 31, 32 and 33 to which the spike 9 is attached. Yes. The front end of the arm 27 b reaches the lower side of the bracket 34. Both end portions 35 of the bracket are buried in the shoe sole 1. The front end of the holder 27 is guided between the shoe sole 1 and the bracket 34. In the heel region, both ends of the cross member 33 engage with recesses 36 provided in the shoe sole 1, and these recesses are covered by a cover plate 37 attached to the shoe sole 1; In the illustration of FIG. 7, the cover plate is shown with the upper part of one of the recesses 36 broken, and the lower return spring 19 acting on the end of the cross member 33 engaging the recess 36 is shown. Show. Regardless of the direction of rotation of the support 27 when the user's body swings, one of the two return springs 19 is. When the foot is lifted up, the holder 27 can be returned to the starting position.

  The illustrated shoe is particularly suitable for use as a golf shoe. It is not necessary that both shoe shoes of a pair of golf shoes have the configuration according to the present invention. For the left-handed lead, it is sufficient that the right shoe has the structure according to the present invention, and for the right-handed lead, the left shoe has the structure according to the present invention.

  The embodiment shown in FIG. 8 is different from the embodiment shown in FIG. 7 in that the arm 27a of the holder 27 that rotates around the bolt 28 has a plate-like shape on the flange side. It is a support 38, and the arm 27b of the holder 27 has a plate-like support 39 at the middle foot portion and the toe portion. The rear end portion of the rear support body 38 and the front end portion of the front support body 39 are respectively engaged with guide grooves provided between the heel portion of the sports shoe and the bracket 40 fixed to the heel portion, Alternatively, on the toe side, the guide groove between the bracket 41 fixed to the shoe sole portion and the shoe sole portion of the sports shoe is engaged. These two brackets 40 and 41 are formed of, for example, a metal plate or a plastic material. The brackets 40 and 41 may be provided with stoppers for restricting the pivoting movement of the holder 27 as necessary. A bolt 28 configured as a screwed bolt is surrounded by a spiral spring 42 whose inner end is fixed to the bolt 28 or fixed to a sleeve fixed to the shoe sole, and the outer end of the spring is attached to the holder 27. For example, it is fixed to a mounting element 43 such as a pin facing the shoe sole. With this spiral spring configuration, when the spiral spring has no restoring force, the holder is held at the center position as shown in FIG. When the holder moves in the clockwise direction or the counterclockwise direction, a restoring force is generated in the spiral spring 42 and acts to return the holder to the center position. The plate-like supports 38 and 39 have a spike shape when used as a golf shoe, and support the engaging member 9 having a stud shape when used as a soccer shoe. It has become.
