The present invention relates to a training device for sports, and more particularly, the present invention relates to a training device for a game of hockey.
Field hockey is one of the oldest and most popular outdoor games played in teams. Also, called hockey, the term field hockey (hockey) is generally used to distinguish it from ice hockey. Hockey is a game that requires that players learn highly technical skills. In hockey, a small hard ball is maneuvered with a hockey stick. Maneuvering the ball is generally referred to as stick work or dribbling. Some of the basic skills desired in field hockey are dribbling (moving the ball), trapping (receiving the ball), passing, and tackling. Field hockey players use stick work to move the ball in the desired direction including left, right, forwards, backward, and diagonally. The stick work is used to maneuver the ball when running and position the ball for passing and shooting. It is difficult to learn to maneuver the ball with a stick. Current methods used for learning the stick work include learning the correct grip, stick motion when dragging or popping the ball, and rotating the stick over the ball to change the direction of the ball through instruction by coaches and practice by players. Becoming an advanced dribbler of the ball can take many years of practice and gameplay. One measure of a player's ability to dribble the ball can be measured by the number of times they can drag the ball over one meter in one minute. At each extreme of the drag left to right and right to left, the stick must be rotated quickly and efficiently over the ball. The most efficient method for rotating the stick over the ball is to have the stick in contact with the ball during the rotation over the top of the ball.
The stick work is used to move the ball with the stick's toe. The left hand rotates the stick from a toe's up position (the forehand or front stick side) to a toe's down position (the reverse stick position). When the stick is in the front stick position, the ball should be centered on the straight part of the stick. When the stick is in the reverse stick position, the ball should be on the end of the toe. During the rotation over the ball from the front stick to the reverse stick position, the stick moves its relative position from the straight part of the stick to the toe. During the rotation over the ball from the reverse stick to the front stick position, the stick moves its relative position from the end of the toe to the straight part of the stick. The right hand is used to move the stick and hence the ball back and forth in front of the player's feet or forwards and backward along the right side of the player or diagonally or in a curve from right to left (the drag). When the ball is being dragged back and forth, at the left and right extremes of the ball movement, the stick will rotate over the ball so that the stick can then move the ball in the opposite direction or stop the ball.
Dribbling has several different axes of movement that the stick moves through when the player is dribbling the ball. The two primary movements of the stick used to propel the ball along the ground and to change the direction of the ball are the movement of the ball sideways or forwards and backward, to the turning over of the stick. There are desired or more efficient movements of the stick that gives the player greater control over the ball and allow the player to move the ball more quickly than less efficient movements of the stick. The first important movement is the rotation of the stick relative to the end of the stick handle. The desired movement is rotating the stick relative to the end of the stick and not to some point below the end of the handle where the left hand or the right hand is holding onto the stick. A line from the center of the end of the handle to the center of the ball is the center of the rotation of the stick around the ball. Players make a mistake by moving the left hand, left and right when rotating the stick. There are many reasons why the stick should be rotated around the end of the center of the handle. If the left hand does not move and the stick is rotated around the end of the center of the end of the handle, then the stick face will move around the ball in the correct position on the ball. In order to develop advanced dribbling skills, the player must learn to roll the right hand down slightly when rotating the stick from the reverse to the front stick position.
The second important movement of the stick is the movement of the end of the stick along a line from left to right and right to left relative to the shoulders or forwards and backward on the right side. The end of the handle is the pivot point for the movement from left to right and from right to left. The stick moves like a clock hand from left to right and from right to left. The movement of the stick along with a line relative to the shoulders is important. While dragging the ball from left to right and from right to left, in most instances it is especially important to maintain the position of the stick face on the same relative position on the ball. The movement of the hands and the stick in a direction not in line with the shoulders is sometimes done in advanced dribbling. When running with the ball and dribbling the ball from left to right or right to left, which is the most common instance of dribbling, it is important to keep the same distance of the hands from the body to maintain the same relative position of the sick face on the ball.
The third important movement of the stick is the turning of the stick over the ball at the extreme left or right movement of the ball with the stick's toe up or down respectively. Learning how to roll the stick over the ball without changing the height of the end of the stick handle and without changing the relative position of the hands relative to the shoulders and the relative position of the hands relative to the ground is difficult and takes many years. Introducing controls over the end of the stick movement with a training device can drastically reduce the amount of time it takes to learn the rotational movement and can be used to refine advanced dribbling skills.
The fourth important movement of the stick is the extension of the stick past the ball when the ball is being dragged to the left. The extension of the stick past the ball prevents the ball from running off the end of the stick. Learning to use the end of the stick as the pivot point and positioning the ball on the straight part of the stick and not the curved part of the stick is key to preventing the ball from running off the end of the stick.
The fifth movement of the stick is the movement of the middle of the handle forwards and backward. This is a more advanced movement that is usually used to move the ball forward and backward in a more upright position. The Sixth movement of the stick is the movement of the right hand slightly up and down during the rotation of the stick over the ball. When the stick rotates over the ball, the stick should move up slightly over the ball. The center of the end of the stick should not change its relative position very much. There are other advanced movements of the stick derived from the basic dribbling movements.
The different dribbling movements are difficult to learn and master. A player starts by learning the basic skills under a supervision of a coach. Learning how to dribble a hockey ball requires that the player does not introduce incorrect movements of the hands or legs or body during the dribbling motion. Any introduction of incorrect movements of the hands or legs or body during the dribbling motion results in exaggerated movements of the stick and undesirable changes of the relative position of the stick face to the ball. The primary mission of the dribbler is to maintain the correct relative position of the face of the stick on the ball, the correct direction of the stick, and the correct motion of the face of the stick. Mistakes include sliding the stick across the face of the ball which results in the stick face traveling on a different line than the line that the ball is traveling results in the ball running off of the end of the stick and the loss of control over the ball. Learning or mastering the skills to control the ball with the hockey stick is difficult and takes a lot of time and practice. Multiple factors are involved in the use of the hockey stick to control the ball including the position and angle of the hockey stick and the motion of the hockey stick along the ground and over the ball. The movement of the stick is controlled by the grip used, the movements of the right and left hands and arms, and the body posture.
Thus, supervised learning in the presence of a coach is important to learn correct techniques and avoid practicing the wrong techniques. However, the supervision of the coach may not always be available. Moreover, in the presence of a coach, the coach cannot devote all the time to a single player. It takes hundreds, if not thousands of hours, to become an advanced dribbler. Therefore, a training device is needed that controls the motion of the stick over the ball and maintains the angle of the stick relative to the ground to assist a player in learning and training their muscle memory, by practicing the correct technique of dribbling a hockey ball.
The following presents a simplified summary of one or more embodiments of the present invention in order to provide a basic understanding of such embodiments. This summary is not an extensive overview of all contemplated embodiments and is intended to neither identify key or critical elements of all embodiments nor delineate the scope of any or all embodiments. Its sole purpose is to present some concepts of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.
The principal object of the present invention is therefore directed to a training device and a method for learning and mastering dribbling skills in a game of hockey by practicing.
It is another object of the present invention to allow a player to improvise their dribbling skills without the supervision of a coach.
It is still another object of the present invention that the training device helps a player to learn a correct technique.
It is yet another object of the present invention that the training device can be used with a standard hockey stick.
It is a further object of the present invention that the training device can be economical to manufacture.
In one aspect, disclosed is a training device and a method for improvising the dribbling skills in the game of hockey. The training device includes a disc of a shape ranging from round to oval. The training device is configured to be mounted to a standard hockey stick. The disc can include a central section and a peripheral rim around the central section. The central section can include a sleeve configured to receive a handle and a shaft of the hockey stick. The sleeve further includes a fastening member configured to secure the training device to a head or the shaft of the hockey stick, wherein the disc extends radially in a direction perpendicular to the length of the shaft. The exact position of the training device on the hockey stick may depend on the dribbling movement being practiced and can be determined by suitable experimentation and minor adjustments can be made as desired by the trainee.
In one aspect, the shape and dimensions of the central section can be varied, for example, the central section can be planar, or consists of a series of spokes extending from the sleeve to the peripheral rim, or the central section can be solid with multiple cutouts, or can resemble a shape of an airfoil i.e., curved near the peripheral rim.
In one aspect, the sleeve can be at the center of the central section. Alternatively, the sleeve can be off-center.
In one aspect, the peripheral rim can have a smooth surface.
In one aspect, the periphery rim can be integral with the central section to form a single unit.
In one aspect the peripheral rim and the central section can be integral, and the central section can be attached to the sleeve.
In one aspect, the training device can further include sensors, such as a gyroscope and accelerometer to detect tilt, rotation, and movement of the training device. The sensor can transmit timing and position information to a cell phone or computer for analysis and competition.
In one aspect, disclosed is a method of training dribbling technique in the game of hockey. The training device can guide the path of a hockey stick in two or more axis of motion during a dribble in order to keep the stick face and toe on the ground and on the ball during the left to right and right to left motion and keep the stick on the ball during the rotation over the ball in order to position the stick face and toe on the ball in the optimal position for the given stick and ball position and to maintain control over the ball.
In one aspect, the disclosed training device can guide the end of a hockey stick during a dribble in order to keep the end of the handle in the same position during the left to right and right to left motion and keep the stick on the ball during the rotation over the ball.

The description is not to be taken in a limiting sense but is made merely to illustrate the general principles of the invention since the scope of the invention will be best defined by the allowed claims of any resulting patent.
Disclosed is a training device, also referred to herein as a training device, for learning and mastering the dribbling technique by practicing in a game of stick and ball, such as field hockey that involves repetitive motions used to control a ball with a sports instrument that has a handle and an end designed to control the ball. The disclosed training device can be used to learn different techniques in addition to the dribbling technique without departing from the scope of the present invention. The following embodiments will be described taking field hockey as an example, however, the scope of the following embodiments should not be limited to the game of field hockey.
In certain embodiments, the training device can stabilize the hockey stick, resulting in a gain of control over the ball while practicing so that the trainee can pay attention to different aspects of the technique and can learn the correct technique by repeatedly practicing the different dribbling movements. The disclosed training device can help the trainee with proper hand positioning and gripping of the hockey stick which may otherwise go unnoticed and the trainee learning incorrect handling. This is the primary reason behind the trainee not learning or practicing the most important movement in dribbling i.e., the rotation of the stick relative to the end of the stick handle. Not controlling the rotation point of the end of the handle can lead to learning the wrong technique. The disclosed training device can help a trainee maintain the correct rotational point.
Referring to
The training device 100 including the disc, the sleeve, and the fastening member can be made from any rigid and lightweight material that does not undesirably increase the weight of the stick. For example, the training device can be made from plastic material or lightweight metal. The peripheral rim 130 of the disc 110 can be smooth or rubberized. The smooth surface of the peripheral rim can slide over a surface smoothly offering less friction. The rubberized surface on the other hand may offer more resistance against the sliding motion but can roll on the surface. The central section can be of a shape ranging from round to oval. The central section can be of a shape from planar to an airfoil shape, as shown in
The central section and the peripheral rim can be separate or integral. When separate, the peripheral rim can be mounted to the central section. When the peripheral rim and the central section are integral, the central section can be integral or separate from the sleeve. When integral, the peripheral rim, the central section, and the sleeve can be integral to form a single unit.
Also, it can be seen in
While dragging the ball with the face of the hockey's toe, the toe either in up or down position should touch the ground, and also the peripheral rim of the training device should be touching the ground, as shown in
Moreover, while dribbling, the user can focus on the rotation of the end of the handle and keeping the toe on the ball, while the angle of the stick can be controlled by the training device. This makes the complex learning task of dribbling easier for the trainee and the trainee can learn the correct technique and perform the movements with or without the supervision of the coach. In one implementation, the distance of the stick to the ground is determined by the distance that the stick has to be from the ground to be in the correct relative position on the ball at each point during the rotation over the ball, such that the toe of the stick can turn over the ball. The angle of the stick relative to a horizontal plane can be proportional to the position of the training device on the shaft of the stick.
In one implementation, the training device mounted to the stick can control the motion of the stick handle during the player's movements of the stick and maintain the end of the stick in an optimal position of the ball during all movements.
In one implementation, the training device can include sensors such as accelerator and gyroscope to track the movements of the training device for analysis. It is also envisioned to use a camera or a laser system to measure the distance that the ball travels left to right, the speed at which the ball travels, the number of repetitions, the percentage of time that the stick is in contact with the ball, the motion of the stick on the different axis, the contact between the stick and ball, the angle for the stick in relation to the ground and during the movement. All the information gathered from the sensors, cameras, or the laser system can be stored in an external memory which can be analyzed later using appropriate analytical techniques. The result of the analysis can be displayed on a screen or printed on a physical medium. The information and the analytical tools can be stored in a mobile phone or a server, including a cloud server, so that the trainee or concerned person such as a coach can access the information anytime and from anywhere. A dashboard can also be developed that displays the performance of the trainee and other statistical analyses of the training in graphical forms and can further show trends over time. Comparisons with the other trainees can also be made using the stored information.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
