Abstract

A soccer kicking tee is disclosed which is especially useful by soccer players to use as a training aid to learn a kicking technique known as kicking with the laces. The tee provides a support for a soccer ball at a prescribed height above the ground plane. A vertical support element interfaces with the bottom of the ball and prevents the ball from rolling or tipping over. This vertical element is supported by a base that spreads out the portion touching the ground and stabilizes the vertical element and the ball and prevents them from tipping over. The shape of the tee minimizes the likelihood that it will tip over when the ball is kicked or struck with the foot. The tee can be used on any surface and can be further secured to the ground with a golf tee or similar stake like element. The vertical support element is pliable enough to easily deflect if the foot comes into contact with it and is stiff enough to support the ball in a static position. The height of the vertical support element can also be adjusted to a lower position.

FIELD OF THE INVENTION

The field of the invention relates generally to sports training devices, such as soccer kick training.

BACKGROUND OF THE INVENTION

From the early days of youth soccer practice throughout the US, around the ages of 7 or 8 years old, a common instruction heard on the field is “Don't kick with your toes, kick with your laces.”
Soccer coaches frequently will instruct young players to kick the ball with the top of their foot; rather than their toes. To illustrate the foregoing technique, the coach will place his toe downward, nearly perpendicular to the grass, and against the side of the soccer ball demonstrating his shoe laces contacting the ball and not his toes. Unfortunately, this is often the extent of the “lace-kick” training. Many youth soccer players will not demonstrate consistent lace-kicks until they are 14 or 15 years of age. Why such difficulty in performing a consistent lace-kick when the key skill of soccer is to master the kick? Human beings lead with their toe when walking. At ages 3-5, children continue leading with the toe when kicking a ball in the yard which reinforces the natural tendencies, thus creating a barrier to learning the correct soccer kick using the laces of the shoe.
To reverse this well ingrained habit of leading first with the toe when kicking the ball, it is necessary to train youth soccer players to experience the “feeling” of kicking with the top of the foot or shoe commonly referred to as the “laces” of the shoe
In the past, small articles such as paper cups and the like have been used to elevate a soccer ball for kicking in order to train lace-kicks. These improvised solutions have several drawbacks. The articles will not stay in place after a kick and therefore offer no consistency over time. The articles typically do not support the soccer ball at an optimal height for training lace-kicks. The articles offer no height adjustment.
The present invention solves the problem of training soccer players to lace-kick by providing a special tee that supports and orients a soccer ball for lace-kicking practice. The special tee elevates the soccer ball slightly so a player can easily place the top of his or her shoe under the ball and connect with the laces resulting in a solid kick. As a result of the soccer ball orientation which encourages proper foot position, through repetition, the lace-kick becomes a natural process and is mastered.
The present invention encourages locking of the kicking foot and placement of the planter's foot and body position over the ball which is important but secondary to the concept of “lace kick” using top of foot.
The present invention introduces the concept of a lace kick at an early age so fun and success are the experience which leads to confidence and skill.

SUMMARY OF THE INVENTION

In one aspect, the present invention includes a training apparatus to teach a soccer player to perform a lace-kick on the soccer ball using the top of his or her foot and orient and fix the foot with respect to the ankle and lower leg. As the foot approaches the soccer ball, the lower leg swings about the knee causing the foot to accelerate into the ball and transfers the maximum energy from the foot into the soccer ball. The training apparatus allows a soccer player to swing the foot extended in a rigid downward position and make contact with the soccer ball without contacting the ground with the toe end of the shoe. The soccer tee device puts the soccer ball in an elevated position above the ground and allows the kicking foot to more easily make contact with the soccer ball at a point slightly lower than the center of gravity, thereby imparting an upward trajectory on the ball. The soccer player gains confidence more quickly by repeating the technique and overcomes the frustration of repeatedly kicking the ball with the toe and failing to impart a lift to the soccer ball.
In another aspect, the present invention elevates the ball off the ground in a stable position and gives the soccer player a visible line of action at a local frame of reference at the tee that projects to the corners of the goal. The soccer player can practice kicks by selecting a target within the bounds of the goal from left to right and from the ground plane to the top bar of the goal. The presence of a goalie often requires last second adjustments in the region of the goal the soccer kicker will target in order to successfully get the ball in the goal and past the goalie. The present invention provides cues to the kicker who needs to primarily focus on the local position of the soccer ball, the trajectory and position of his or her foot as it swings through and strikes the ball, and the position of the planter foot adjacent to the ball. The awareness of the position of the goal is translated to the local position of the ball by the present invention.
In yet another aspect, the present invention provides dynamic stability for the ball and remains in position after a kick is completed. The soccer player can place the ball repeatedly in the same position as the initial kick. Stability enhancing features on the present invention increase the training consistency of each kick thereby increasing the skill.
The placement of the non-kicking foot or plant foot is also important to learn the proper technique to make a lace kick. The present invention provides a cue to the soccer player to place their non-kicking foot or plant foot adjacent to the soccer tee. The proper placement of the non-kicking foot or plant foot provides a kicking foot line of action to impact the ball parallel or at a slight upward angle to provide the right amount of lift on the ball. After the ball is kicked, the present invention provides a visual cue and reminder for the correct position of the plant foot relative to the position of the soccer ball prior to the kick. The soccer kicker can then adjust subsequent kicks and better align the plant foot directly adjacent to the soccer ball which controls the direction of ball flight.
In still another aspect, the present invention minimizes the reaction force on the soccer kicker's foot if the toe inadvertently comes into contact with the soccer tee device. The vertical supporting element of the device will easily deflect and deform as the kicking foot swings through it. The force required to deflect the vertical supporting element is low, and avoids pain or injury to the soccer kicker. The force is also small enough to be reacted through the base to minimize the likelihood that the soccer tee will be displaced from its original position. The weight of the soccer tee device is also a consideration in the less likely event that he kicking foot contacts the base of the soccer tee device directly. Any restraint devices or anchors to maintain the position of the soccer tee device with respect to the ground location are designed to give a way if sufficient force or energy of a moving mass of the foot is imparted.
The foregoing and other objects, features, and advantages of the invention will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures wherein the scale depicted is approximate.

Referring generally to FIGS. 1-28, an apparatus for training soccer players to lace-kick incudes a base member (100), and a ball support riser (200) extending therefrom. A soccer ball (3) is positioned to rest at the upper edge (210) of the ball support member to prepare it for being struck with the kicking shoe. Although a soccer ball is used as an example, the apparatus may be useful for any number of different sports where holding a ball at a specific elevation or being able to adjust the elevation aides in practice or during game play. The apparatus may be useful in holding any number of other types of balls including but not limited to a golf ball, baseball, football, ping pong ball, rugby ball, tennis ball, volleyball, or kick ball. All or portions of the support member are preferably sufficiently deformable when struck with a kicker's shoe. The base member is configured for contact with the ground or floor and is low profile and flip resistant when used as intended. The base member may be configured axisymmetric about a vertical axis through the center of the ball support member or may be symmetric about a vertical plane aligned with the forward and aft directions. The base member possesses a beveled edge (110) to minimize the chance of contact with the kicking foot. The beveled edge may run the entire circumference or perimeter of the base or may be located in the direction of an approaching kicker. The support member may be unitary and inseparable with the base, or a separate element. The support member can be of one, or multi-piece construction. The base member and support member may be made of the same materials or materials having different properties such as elasticity. For example, the support member can be an elastomer, while the base member material is relatively rigid. The base may be weighted, for example, by overmolding the base member over a weight, or affixing a weight to the base. The base can possess a rectilinear or circular shape or have stabilizing projections such as wings wherein the particular arrangement of wings shown in embodiments herein provides desirable properties to the apparatus.
Referring to FIGS. 1-6, the figures show respectively an apparatus for training soccer players to lace-kick incudes a circular base member (100), and a ball support riser (200) extending therefrom. A soccer ball made from 12 pentagons and 20 hexagon panels is sitting on top of the ball support riser (200). The ball support member is a separate element from the base (100). The base member in one embodiment according to the present invention is configured axisymmetric about a vertical axis (12) through the center of the ball support member. A soccer ball (3) is positioned to rest at the upper edge (210) of the ball support member to prepare it for being struck with the kicking shoe. The stability of the static soccer ball (3) sitting on the ball support riser (200) is established by first, the inside diameter (231) of the ball support riser (200), and second, by the edge of the base (120). The static stability is determined by establishing the angle (11) between the vertical axis (12) passing through the ball's center of gravity (14) and a tilted gravity vector (13) passing through the edge (120) of the base or the edge of the ball support (210). A minimum static stability angle of 15 degrees is necessary to accommodate an uneven or tilted ground surface (10). The lower riser retention flange (220) prevents the ball support riser (200) from completely passing up through the riser support aperture (130) in the base (100). The countersink (140) allows the riser retention flange (220) to be flush with the bottom surface (150) of the base (100). The bottom surface may be textured to decrease the likelihood of base (100) slipping relative to the floor or ground during repeated use. The tolerance between the riser support aperture (130) in the base (100) and the outer diameter of the ball support riser (200) is close enough and the coefficient of friction of the material high enough to prevent displacement relative to each other during use while allowing assembly between the two elements using low to moderate force. For instance, this area of tight tolerance can be narrowed or limited to a smaller area or feature. The entire contact area between the two parts does not require a tight tolerance in order to sufficiently retain them during usage. The tight contact area can be limited to a narrow ring of raised area or a nub or a series of localized bumps. The raised distance can be small enough to mainatin a standard type of mold for production of part. The material used for the ball support riser (200) is sufficiently deformable when struck with a kicker's shoe, and capable of supporting the soccer ball in a static position elevated to a height (240) above the ground plane (10), The inside diameter (231) of the ball support riser (200) may be a cylinder or cone that projects all the way from bottom to top surface. For instance, a conical shaped ball support riser may be used to allow stacking of multiple cones one inserted inside the adjacent one for better shelf space or disply space utilization. The base member possesses a beveled edge (110) to minimize the chance of contact with the kicking foot. The beveled edge runs the entire circumference of the base and has an edge (120) rounded sufficiently to prevent injury if struck by the kicking foot.
Referring to FIGS. 7 and 8, the figures show respectively an apparatus for training soccer players to lace-kick comprising the second embodiment that includes a circular base member (100), and a shortened tubular ball support member (250) extending therefrom. A Brazuca soccer ball (3) is sitting on the short ball support member (250). The short ball support member (250) is a separate element from the base (100). The base member in one embodiment according to the present invention is configured axisymmetric about a vertical axis through the center of the ball support member. The height (242) of the upper edge (210) supporting the soccer ball (3) is reduced from that of the ball support riser (200) shown in FIGS. 1-3 and 5-6 and can be used as the soccer kicker gains skill and is transitioning to a more difficult practice drill before kicking directly off of the ground or floor surface.
Referring to FIGS. 9 and 10, the figures show respectively an apparatus for training soccer players to lace-kick comprising the third embodiment that includes a circular base member (100), and a weighted or ballasted tubular ball support member (260) extending therefrom. The inside surface (231) of the ball support member may be a cylinder or cone that spans from the upper edge (210) to a floor surface (211). The ballasted ball support member (260) may be a separate element from the base (100) or may be integrated with the base. The weight (270) may be any of a number of dense materials including steel, iron, lead, or the same or similar material used for the ball support member (260), rubber, plastic, or an elastomer. The weight (270) may be overmolded into the ball support member (260) or may be removable. A sand or shot filler, or a liquid such as water or a combination may be used as a weight. The weight's position towards the ground plane (10) insures a low center of gravity for the apparatus and improves the flip over resistance. Any weight will increase the dynamic stability of the tee apparatus. The amount of weight needed to be effective is proportional to the force (30) required to deform the ball support riser (200) when the foot comes into inadvertent contact. Additional weight (270) in the range of ¼ to 5 pounds would be sufficient to improve overturning stability. The weight can be placed directly on the bottom surface (211) or in a pocket formed by at least 2 floors that close out the inside surface (231). A weight material that is able to deform and is contained during kicking impacts reduces the chance of injury to the foot and from flying debris.
Referring to FIGS. 11 and 12, the figures show respectively, an apparatus for training soccer players to lace-kick comprising the forth embodiment that includes a shaped base member (101), made with a plurality of wings (160) equally spaced circumferentially around and a frusto-conic shaped ball support riser flange (280) extending therefrom. The ball support riser flange (280) is unitary and inseparable with the base (101). The base member is configured axisymmetric about a vertical axis through the center of the ball support riser flange (280). A soccer ball (3) is positioned to rest at the upper edge (210) of the ball support member to prepare it for being struck with the kicking shoe. The material used for the ball support riser flange (280) is sufficiently deformable when struck with a kicker's shoe, and capable of supporting the soccer ball in a static position elevated to a height (240) above the ground plane (10), The inside surface of the ball support riser flange (280) shown in FIG. 12 forms a hollow cavity in the ball support member. The base member possesses a beveled edge (110) at the distal end of each wing (160) to minimize the chance of contact with the kicking foot. The bevel is blended into the wing shape with a circular arc (121) as viewed in the plan view in FIG. 11. The bevel edge (120) should be rounded sufficiently to prevent injury if struck directly by the kicking foot. A one piece axisymmetric tee (400) can alternatively be made of any range of plastics or rubbers with a material hardness from a shore D of (35) to (85) or Rockwell R hardness between (100) and (150). The apparatus can also be made of any metal material including zinc, aluminum, tin, or steel although the safety benefits of a deformable material would be given up.
Referring to FIGS. 13 and 14, the figures show respectively an apparatus for training soccer players to lace-kick of the fifth embodiment incudes a rectilinear base member (102), made with a plurality of stakes (500) and a separate tubular shaped ball support riser (200) extending therefrom. Initially, metal tent stakes were used to secure the tee base (102) to the ground. There are different kinds of stakes (500) that can be used to more firmly secure the base (102) to the ground using such features as barbed shafts making then easy to push into the ground but harder to pull out. Other types of stakes have pan heads that are broad and spread the tension force in the stake out to a larger area of the base. This type of stake head would also make it less likely that the stake could pull through the stake support aperture (180). The base (102) is symmetric about a vertical plane aligned with the forward and aft directions. By positioning the base with the elongated end farthest from and the shorted edge closest to the direction of the approaching kicker (16) the dynamic rollover stability is improved. A force applied in the direction of the approaching kicker (16) is resisted about the dynamic tipping axis E-E by the turnover arm (24). The turnover arm (21) is shorter than (24) because it only needs to maintain the stability of the static ball (3) due to ground imperfections and tilt. The static tipping axis (B-B) tends to tip over the minimum static tipping arm (21). The stability of the apparatus (402) is improved by the weight of the base (102). The base member possesses a beveled edge (110) to minimize the chance of contact with the kicking foot. The beveled edge runs on the leading edge of the base and has an edge (120) rounded sufficiently to prevent injury if struck by the kicking foot. The additional weight of the base improves the turnover stability in areas such as gymnasium floors or on artificial turf. The weight of the base can be increased by making it thicker or using a denser material such as a filled urethane with dense additive material. The flexibility can be retained while shifting the center of gravity to a lower more stable point closer to the ground plane (10). The base surface texture (150) can be selected to increase the coefficient of friction and prevent sliding along the ground plane (10) due to force applied by the kicker. Other surface textures, patterns or features such as ridges parallel to the leading edge (120) can improve the resistance to slipping along the ground plane (10) on loose material or grass. Another way to further improve the turnover stability of the apparatus (402) is to pin the corners with stakes (500). In some ground conditions, a stake (500) can be inserted into a compacted ground material such as soil or a turf root system. A golf tee is one such common stake (500) shown in FIGS. 13 and 14. The stakes (500) are placed through the stake support apertures (180) and into the ground. The ball support riser (200) is shown separately in FIGS. 5 and 6 and can be used interchangeably with other bases (100) and works in same way as described in paragraph [0048].
Referring to FIGS. 15 and 16, the figures show respectively an apparatus (402) for training soccer players to lace-kick of the sixth embodiment incudes a base member (102) with a plurality of wings (160 and 161) elongated to different amounts and a separate tubular shaped ball support riser (200) extending therefrom. The base (102) is symmetric about a vertical plane aligned with the forward and aft directions. By positioning the base with the elongated wing (161) farthest from and the shorted wing (160) closest to the direction of the approaching kicker (16) the dynamic rollover stability is improved over that of an axisymmetric base designed primarily for static turnover stability. The leading edge of the wing (160) is a beveled edge (110) to minimize the chance of contact with the kicking foot. Potential injury to the ball kicker is minimized by reducing the area of the base (102) and its volume and resulting weight. The ball support riser (200) is essentially the same as shown in FIGS. 5 and 6 with the exception of a slightly smaller riser retention flange (220) to allow base material to be removed. The orientation of the wings and removal of base material does affect the dynamic stability of the apparatus (402). The primary dynamic stability about axis E-E and overturning arm (24) is essentially the same as referred to on paragraph [0048]. The static stability is also similar in the direct of the leading edge about axis B-B and arm (21). However the off axis stability modes are reduced. The apparatus (402) can also tip about axis E-E and arm (24) if there is a sufficient component of force applied at an angle to the primary kicking direction (16). All of the axis static stability axes B-B and arms 21 must also be taken into account. The thickness of the wing (111) must be sufficient to prevent excessive deformation when the kicking force is applied to the upper edge (210) of the ball support member and causing a bending moment in the wing (161). The modulus of elasticity or the shore hardness or durometer of the rubber of the base material can be increased to improve resistance to bending moment.
FIG. 17 is an isometric view of the seventh embodiment of the present invention consisting of a base (102) shaped into a pair of wings (161) symmetrically placed about a fore aft plane normal to the ground and aligned radially around and a tubular shaped ball support riser (200) extending therefrom. Two wings (161) protrude toward the back of the base and are stiffened with aft flanges (170). An aperture (180) can be used for an anchoring penetrating member that is optional depending on the surface used.
FIG. 18 is a view looking at the top surface of the present invention. The vertical support riser (200) is used to support the ball (3) at an extra height above the ground plane (10). The vertical support riser (200) shown in FIG. 18 is a hollow tube and extends up from the base (102) to contact the ball (3) at the ball contact surface (210). The inside diameter of the vertical support element (231) is sized to best support the ball (3) in a static position and prevent the ball from rolling or tipping over. The inside diameter (231) has been shown to work in a preferred minimum range of 2¼ to 2½ inches for use on all surfaces. A smaller inside diameter (231) can be used on surfaces that are essentially level such as on gymnasium floors. Some tolerance is needed to maintain stability of the ball and apparatus (410) when used on a surface that is not truly flat. The apparatus (410) should work even if the surface is slanted up to 15 degrees with respect to the ground plane (10). The trim of the base (102) resembles an arrow shape. The present invention works best when the kicker approaches the apparatus (410) as shown in direction 16. The centerline of the apparatus (410) is aligned roughly to the center of the goal. The kicker then chooses a target area within the goal either right, center or left. The angle between right to center to left is represented by the angle (17). The apparatus (410) works best when the kicker approaches from any direction within the range angle (17). The two wings (161) of the base (102) are positioned to resist turnover when the kicker contacts the ball. The two critical static turnover axes are shown in FIG. 18 as D-D. These axes converge at the leading edge of the apparatus (410) where the position of a single stake is located. The position of these axes through to the stake (500) position minimizes the tendency for the base to rotate with respect to the ground plane (10). A bevel (110) at the leading edge of the base decreases the likelihood that the kicker's foot will strike the base. The leading edge is also rounded (120) to protect the kicker's foot if contact is made.
FIG. 19 is an elevation view from the right side of the present invention. A soccer ball (3) is supported above the ground plane (10) at a beginner height (240). The ball support riser (200) is used to support the ball (3) at an extra height (240) above the ground plane (10). The ball support element (200) shown in FIG. 19 extends up from the base (102) to contact the ball (3) at the ball contact surface edge (210). The height (240) between the ground plane and the ball contact surface edge (210) best ranges between 2.5″ inches for the beginner goal lace kicker and can be reduced from there as the goal kicker gains experience and confidence after usage and preference. A flange (170) is shown protruding normal to the base (102) and tapered from the back of the base (102) towards the vertical support element. The flange blends into the ball support element. The base (102) can be thinned up if additional flanges (170) are incorporated into the base (101). The flange acts as a stiffening element and increases the rigidity of the apparatus (410). A support aperture (180) is located at the front of the apparatus (410). A stake (500) can be placed into the support aperture (180) if additional stability is desired when using the apparatus (410) on compacted soil or turf surfaces.
FIG. 20 is a section cut through the center vertical plane along the axis of symmetry of the present invention. The section cut 19 shows the wall of the soccer ball (3) making contact with the ball support riser (200) at ball contact surface edge (210). The ball support riser (200) is integrated into the base (102) as one piece in this seventh embodiment. The vertical support element is tubular. The apparatus (410) can be placed on any surface. The apparatus (410) can be used indoors and placed directly on gymnasium floors or artificial turf. The safest use of the apparatus is when the weight is minimized. A minimum weight apparatus offers the least impact forces if the foot comes into contact. The strength of the apparatus (410) only has to be sufficient to support the static weight of a soccer ball. Although a variety of materials can be used to make the device, a compliant material such as rubber enables the device to easily deform if struck by the kicking foot to minimize the reaction force on the foot. The force from a strike of the kicking foot (30) is reacted by shear between the base and the ground (31) at the bottom surface (150) of the base. An over turning moment is caused by the height of the kicking force above the ground plane (10). The over turning moment is reacted by the a downward tension force (32) in the penetrating stake member and a downward force of the weight (36) of the apparatus (410) and a distributed compression force (34) that increases along the wings aft of the ball support. The resulting compression force (33) couples with the tension force (32) and the tee weight (36) to balance the moment. The texture of the bottom surface can be tailored to react the combination of shear and compression force and any sliding force trying to rotate the base with respect to the ground surface (10). The bottom surface (150) of the base can be textured to increase the coefficient of friction and prevent sliding along the ground plane (10) due to force applied by the kicker. Other surface textures, patterns or features such as ridges can improve the resistance to slipping along the ground plane (10) on loose material or grass.
The ability to deform is most important for the ball support element (200). The likelihood of striking the base (102) is less. The stability of the apparatus (410) is improved if the center of gravity is shifted lower. The density of the base (102) material can be higher than the ball support riser (200) to help lower the center of gravity and improve the turnover stability. Another way to improve the turnover stability of the apparatus (410) is to pin the leading edge with a stake (500). A stake (500) can be inserted into a compacted ground material such as soil or a turf root system. A golf tee is one such common stake (500) shown in FIGS. 19 and 20. Golf tees are commonly made from wood or a plastic material. The stake (500) is placed through the support aperture (180) and into the ground. The stake (500) is allowed to break upon impact force to insure safety and reduce force applied to the striking foot. The stake should be made of light frangible materials that can easily break upon buildup of higher forces. Golf tees are made from wood and are designed to break upon direct impact with a club. The use of lightweight materials for the stake (500) also reduces the chance of injury due to flying debris. Another way to control the buildup of excessive resistance is to allow the head of the stake (500) to pull through the aperture (180) in the base (102). This approach can be enhanced by tapering the support aperture (180) to be larger in diameter at the upper surface of the base (102) and smaller at the lower surface of the base (102) that is in contact with the ground plane (10).
Referring to FIGS. 21 and 24, the figures show respectively an apparatus for training soccer players to lace-kick of the eighth embodiment incudes a ball support member shown with an extendable height riser (290) that may be turned outside-in to support the ball at a lower relative position. The extendable height riser (290) can be inverted by pushing down from the top or pulling down from the bottom on the diaphragm (237) to put a distributed force around its circumference and causing the tube wall (236) to roll around the edge of the tube (210). For this case, the apparatus (410) with the extensible height riser (290) that can be inverted is preferably an elastomer having a shore A value of between (20) and (80) and a wall thickness (236) between 0.03 inches and 0.10 inches. For example, a combination of wall thickness between 0.040 and 0.060 inches and a shore A between 50 and 60 allows the wall to easily invert and form a new edge (210) rigid enough to support the ball (3). Once the diaphragm (237) is pushed downward to reduce the riser height, it tends to stay oriented in a downward convex position because of the residual compression around its circumference. The diaphragm (237) can be a solid member as shown or can be perforated with any number of holes in the center and along its circumference to facilitate grabbing it with fingers from either top or bottom direction. For example a hole nearly the size of the inner diameter (231) of the extendable height riser (290) can be used as shown in FIG. 26. The tube wall can then be inverted to the outside. A buildup of material or a bead can be used at the edge of the riser (210) to help stabilize the walls (236) under the loading from the ball. A bead allows the cylinderical shape of the riser structure to deform easily during engagement with the kicking foot. Vertical ribs can also be used to break up the thin walled conical or tubular riser into tall thin sections to improve its ability to support a ball (3) while maintaining compliance during engagement with the kicking foot. For instance, Ribs and beads can be used in any of the riser embodiments. The ribs can be locally transitioned away and eliminated in regions where the riser hinges or inverts to change its height. The ribs above and below the fold area can also be located at different positions in order to avoid interference in the folded position and can be located either internal to the conical or tube riser or external. A slight conical angle, for example, is also useful to prevent interference of bead or rib features in the folded position.
FIG. 21 is a view looking at the top surface consisting of a base (102) shaped into a pair of wings (161) symmetrically placed about a fore aft plane normal to the ground and aligned radially around and a tubular shaped extendable height riser (290) extending therefrom. Two wings (161) protrude toward the back of the base. The extendable vertical height riser (290) is used to support the ball (3) at an extra height above the ground plane (10). The extendable vertical height riser (290) shown in FIG. 22 is a hollow tube and extends up from the base (102) to contact the ball (3) at the ball contact surface (210). The inside surface of the tube wall in the folded position (235) is in preloaded contact between upper and lower portions. The outer portion of the tube stretches as the inner portion compresses to generate pressure at surface (235) between the layers and increasing the resistance to slipping. The section cut 22 shows the wall of the soccer ball (3) making contact with the folded over edge (210) of the extendable height riser (290). This can only be done if the device is made from a pliable deformable material. The high coefficient of friction of a rubber type material keeps the tube from sliding back out once it is in position and during kicks. A variety of reduced heights (242) are obtained with a simple one piece apparatus (410). Using this method the height of the support member can be reduced by one half. The height (240) starting at 2½inches can be reduced to 1¼inches. A flange (170) is shown protruding normal to the base (102) and tapered from the back of the base (102) towards the vertical support element. The flange blends into the ball support element. The flange acts as a stiffening element and increases the rigidity of the apparatus (410). The apparatus (410) is shown without additional stability means from staking and can be used on a variety of surfaces including artificial turf, wood and concrete or a rubber playing surface without the aid of stakes.
Referring to FIGS. 25 and 26, the figures show respectfully an apparatus for training soccer players to lace-kick of the ninth embodiment that includes a ball support member shown with an extendable height riser with an open top. FIG. 25 is a view looking at the top surface consisting of a base (102) shaped into a pair of wings (161). The height of the ball support riser (290) can be adjusted lower by rolling the thin elastomeric top edge inside-out, as shown, or outside-in of itself. The tube wall thickness (236) must be thick enough to support the ball (3) and thin enough to allow the edge to be folded around and outside or inside of itself without buckling. The tube thickness is best between 0.03 to 0.10 inches. The inside surface of the tube wall in the folded position (235) is in preloaded contact between upper and lower portions. The outer portion of the tube stretches as the inner portion compresses to generate pressure at surface (235) between the layers and increasing the resistance to slipping. The section cut 26-26 shows the wall of the soccer ball (3) making contact with the folded over edge (210) of the extendable ball support element height riser (290). This can only be done if the device is made from a pliable deformable material. The high coefficient of friction of a rubber type material keeps the tube from sliding back out once it is in position and during kicks. A variety of reduced heights (242) are obtained with a simple one piece apparatus (410). [0061] Referring to FIGS. 27 and 28, the figures show respectively an apparatus for training soccer players to lace-kick of the tenth embodiment that includes a ball support member shown with an extendable height riser.
FIG. 27 is a view looking at the top surface consisting of a base (102) shaped into a pair of wings (161) symmetrically placed about a fore aft plane normal to the ground and aligned radially around and a tubular shaped riser flange (280) extending therefrom. A riser (292) is inserted into the tubular shaped riser flange (280) to raise the level of the ball support edge (210). Two wings (161) protrude toward the back of the base. The height of the riser (292) can be adjusted lower by pushing the outer surface of the riser (292) against the inner surface of the tubular flange (293). The tolerance between the outer diameter of the riser (292) and the inner surface of the tubular flange (235) is close enough and the coefficient of friction of the material high enough to prevent displacement relative to each other during use while allowing assembly between the two elements using low to moderate force, At the maximum design height, (240) the adjustable tube riser (292) must be long enough to allow an overlap distance (245) in order for enough engagement between the two pieces to maintain their respective positions. An alternate embodiment is for the surfaces to be threaded allowing the riser to be turned to lower or raise the ball's position. Still another embodiment is for the riser to slide down through the tubular flange until it bottoms out against either the ground or a floor along the plane of the base and provides a single ball height position. For instance, a tall ball support riser (200) with a riser retention flange (220) can be inserted inside the riser flange (280) to increase the ball support height to the full beginner height (240). The contact surfaces between the tall ball support riser (200) and the riser retention flange (220) can be a conical if raised features are used as described in paragraph [0048] to retain them in position during usage. In still another embodiment, the riser can be completely removed allowing the ball to rest directly on the edge of the tubular riser flange (280) at a lower intermediate height position (242). In addition to the aft flanges (170) behind the tubular riser flange (280), FIGS. 27 and 28 also show leading edge flanges (171) projecting along the lines of the leading edge bevel (110) to help deflect the kickers foot up and over the base in case of a low trajectory. The leading edge flanges (171) and the leading edge of the base (102) also act together to deflect in the case of a direct kick to cushion any impact allowing for a crushable zone and thereby reducing the force imparted on the shoe of the kicker. The leading edge flanges also protect the stake (500) if used in the provided aperture (180). The crush zone is particularly useful in preventing injury if a ball support member (260) shown in FIG. 10 is used with a counterweight or ballast (270). Although a variety of materials can be used to make the device, a complaint material such as rubber enables the device to easily deform if struck by the kicking foot to minimize the reaction force on the foot. Note that all of the bases (100), (102) can be molded in a closed cavity tool with a single parting plane.
The method for selecting a tee is dependent on the type of ground surface the tee will be used on. For an interior hard surface floor such as a wood gymnasium, rubber court surface, concrete surface or artificial turf over a hard surface, the tees shown in all eight embodiments shown in FIGS. 1 through 24 can be used without a penetrating anchor member (500). The stability of the tee without the penetrating member (500) can be improved by using a ballasted ball support member (260) as shown in FIG. 10. The stability of a ballasted ball support member (260) or a heavy base can be increased by using a more compliant material with a lower durometer or modulus of elasticity to reduce the load imparted by a striking foot (30) into the tee. A penetrating member (500) can be used on a grass or dirt surface where the soil has sufficient compaction to allow the anchor member to be inserted.
The initial “Lace Kick” Training Method uses a Soccer Tee to introduce a soccer player to the proper kicking technique by standing at the tee and practicing kicks. The “Lace Kick” training method is primarily useful to develop confidence in soccer players using the Soccer Tee for two reasons. Firstly, it is a natural step by step progression from beginner through intermediate and advanced stages and secondly, the use of an elevated Soccer Tee allows soccer players to experience early success and have fun succeeding. The equipment required is a soccer ball, a soccer goal net and a Soccer Tee. Set up by establishing a desired distance between goal net and placement of the Soccer Tee. It is recommended to begin with a short distance (6 to 10 feet) as the primary goal of the “Lace Kick” training is to gain confidence in the feeling of a successful “Lace Kick ” vs. the distance of the kick. The following represent exemplary steps to master a lace-kick: Step 1: Select the appropriate tee for use on the practice surface; Step 2: Align a bilaterally symmetric tee with the kicking direction or target. If a goal is used as a target, align the line of symmetry with the center of the goal. For embodiments 8 and 9, the two wings (161) should align toward the right and left vertical goal bars. The player can then relate to the global target zone while keeping focus on the local frame of reference at the ball; Step 3: Place soccer ball on Soccer Tee using beginner ball height (240); Step 4: Place Planter foot (non-kicking foot) next to side arm (161); Step 5: Lock the ankle and kicking foot with toes pointed downward almost perpendicular to ground level; Step 6: Stand on Planter Foot (or take small step with planter foot for forward momentum), and swing top of foot (laces of kicking shoe) through the soccer ball; Step 7: Replace soccer ball on beginner ball height (240) and repeat. Continue repetition of Step 2 thru Step 6; Step 8: Once Steps 2-6 for beginner ball height are successfully mastered, advance to intermediate ball height (242) by either adjusting the Soccer Tee to a lower position or by substituting another shorter Soccer Tee; Step 9: Adjust ball height switching the Ball Support (240) to (242) which reduces the height of ball to the ground level offering more challenge to youth soccer player. As an option, for convenience, you may simply move over a second Soccer Tee with Intermediate ball height in place; Step 10: Repeat steps 2 thru 6 at intermediate ball height until youth player develops consistent and successful “ Lace Kick ” using top of contact with foot or the laces of kicking shoe.” Once Steps 1-4 for intermediate ball height is successfully mastered, move to final stage of advanced ball height which is now placing the soccer ball on the grass or ground level without the Soccer Tee; Step 11: Repeat steps 4 through 6 at advanced ball height (on ground level) until youth player develops consistent and successful “ Lace Kick ” into goal net. Note: Using the Soccer Tee Lace Kick method provides an elevation of the soccer ball to increase the early success a soccer player can experience kicking a successful lace kick. The early success provides the soccer player to receive positive reinforcement from the soccer coach, private trainer or parent which builds confidence and enjoyment for the soccer player. In turn, the confidence and fun result in having fun which is a large part and purpose of the Soccer Tee Lace Kick Method.
The subsequent “Lace Kick” Training Method uses a Soccer Tee is to introduce a soccer player to the proper kicking technique by running at the tee. The equipment required is a soccer ball, a soccer goal net and a Soccer Tee. Set up by establishing a desired distance between goal net and placement of the Soccer Tee. It is recommended to begin with a short distance (6 to 10 feet) as the primary goal of the “Lace Kick” training is to gain confidence in the feeling of a successful “Lace Kick ” vs. the distance of the kick. Exemplary steps are: Step 1: Select the appropriate tee for use on the practice surface; Step 2: Align a bilaterally symmetric tee with the kicking direction or target. If a goal is used as a target, align the line of symmetry with the center of the goal. For embodiments 8 and 9, the two wings (161) should align toward the right and left vertical goal bars. The player can then relate to the global target zone while keeping focus on the local frame of reference at the ball; Step 3: Place soccer ball on Soccer Tee using beginner ball height (240); Step 4: Stand behind and run toward ball while timing the steps in order to get planter foot in proper position lateral to the tee; Step 5: Lock the ankle and kicking foot with toes pointed downward almost perpendicular to ground level just before contacting ball. After contact note the position of the planter foot with respect to the placement of the tee; Step 6: Repeat steps 2 through 5 at beginner height until steps are mastered and kicks are consistently made; Step 7: Reduce height of ball elevation to intermediate level (242) or use a second tee that has a reduced height; Step 8: Repeat steps 2 through 5 with the tee at a reduced height until ball is consistently kicked at desired trajectory at desired velocity; Step 9: Repeat steps 3 through 5 at advanced height with ball in direct contact with ground until consistently kicked at desired trajectory and at desired velocity; Step 10: Repeat steps 2 through 9 while kicking into goal; Step 11: Repeat steps 2 through 9 while kicking into goal past a defending goalie.
