Description

FIELD OF THE INVENTION

The present invention relates generally to systems for training and practicing the sport game of lacrosse. In particular, this invention is related to a lacrosse training system with or without a partner(s) and in a limited space and/or environment.

BACKGROUND OF THE INVENTION

Lacrosse is a spring and summer team sport of Native American origin played with netted sticks called crosses. The world's first official game was played at patrician Upper Canada College in 1867. Today, lacrosse is played internationally as a 12 person per side game for women and as a 10 person per side game for men with differences in playing rules and equipments. The field of play is approximately 110 yards (100 m) long and 40 yards (37 m) wide. The goals are 6 feet (1.8 m) by 6 feet and contain a mesh netting similar to an ice hockey goal. The principle of the game is to project a small solid rubber ball into the opposing team's goal with a crosse (lacrosse stick) which is usually made of wood with a shaped net pocket at the end.
Players line up, each carrying a crosse, based on offensive players called “attackmen”, “midfielders” or “middies”, “defensemen”, and a single goaltender, or “goalie” per team. The attackman's responsibility is to score goals. Players scoop the ball off the ground and hurl the ball in the air to other players. Players are allowed to run carrying the ball with their stick. In men's lacrosse, players may kick the ball, as well as cover it with their sticks. Play is typically quite fast, and resembles a combination of soccer, basketball and field hockey. Players are permitted to hit one another with their bodies and sticks, although some rules govern the manner in which this may be done. Therefore players are protected by wearing helmets and heavy padded gloves.
Lacrosse players need to master the different skills to compete in the game such as:

- Catching and cradling—holding the ball in the stick pocket;
- Cutting—a movement by an offensive player without the ball, toward the opponent's goal, in anticipation of a feed and shot;
- Feeding and passing—passing the ball to a teammate who is in position for a shot on goal;
- Scooping—an act of picking up a loose ball with the crosse;
- Screening, Shooting, etc; and most importantly
- Checking, a defensive technique in which a series of short, sharp, controlled strikes to an opponent's stick is used to force a player carrying the ball to drop it. There are different types of checking such as Poke Check—a stick check in which the player pokes the head of his stick at an opponent's stick through the top hand by pushing with the bottom hand, Slap Check—a stick check in which a player slaps the head of his stick against his opponent's stick and Wrap Check—a one-handed check in which the defender swings his stick around his opponent's body to dislodge the ball.

There are no available training devices in the market specially designed for lacrosse checking skills practice. Coaches and players usually resort to the traditional one-on-one checking practice where one player acts as an opponent holding the ball in his/her crosse pocket while the other player try to dislodge the ball. The key problem of this method is that individual practice is impossible.
During checking moves, opposing players usually engage in a tug-of-war situation in reverse where each player is trying to fend off the other by pushing against each other. In order to increase strength and stamina, some players use sleds that are designed for football practice. However, sleds are not catered for lacrosse training and henceforth not very effective.

ADVANTAGES AND SUMMARY OF THE INVENTION

An object and advantage of the present invention is to provide a training system that allows individual training with or without a partner. Players can simply set the system up and off by manually moving the revolving arm 115 of the lacrosse training system 100 of the present invention in one direction. Then, players could try to tackle the lacrosse training system as if it was their opponents. Thus to improve their eye-hand co-ordination, strength, lacrosse stick skills etc. which are important to improving checking skills.
Another object and advantage of the present invention is to provide random movements of a lacrosse stick which is otherwise impossible to emulate by a training partner. The randomness of movements of the lacrosse stick can help improve players' reflex motion and anticipation of quick movement.
Another object and advantage of the present invention is to that it needs no power to operate. All users need to do to start or initiate the system is to simply move the revolving arm 115 manually, or with a powered motor, in either direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The description that follows is presented to enable one skilled in the art to make and use the present invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principals discussed below may be applied to other embodiments and applications without departing from the scope and spirit of the invention. Therefore, the invention is not intended to be limited to the embodiments disclosed, but the invention is to be given the largest possible scope which is consistent with the principals and features described herein.
It will be understood that in the event parts of different embodiments have similar functions or uses, they may have been given similar or identical reference numerals and descriptions. It will be understood that such duplication of reference numerals is intended solely for efficiency and ease of understanding the present invention, and are not to be construed as limiting in any way, or as implying that the various embodiments themselves are identical.
FIG. 1A is a representative isometric view of a preferred embodiment of the lacrosse training system 100 of the present invention. FIG. 2A is a representative top view of a preferred embodiment of the lacrosse training system 100 of the present invention. FIG. 2B is a representative detail view of a preferred embodiment of the movable hinge system 122 of the present invention.
As shown in FIG. 1A, the lacrosse training system 100 of the present invention mainly consists of a main post 104, horizontal support rod 114 and springs 116 system and lacrosse stick 120.
In a preferred embodiment, the main post 104 is an elongated tubular structure made of light and strong metal such as aluminum, steel, fiberglass, wood, composite, or other natural or synthetic material. The total length of main post 104 should be about the average height of a person around 5-6.5 ft., or more or less. The diameter of main post 104 should be around 1-3 inches, or more or less, and the cross-sectional shape of main post 104 can be circular, triangular, square or other. In a preferred embodiment, main post 104 is erected essentially vertically and attached rigidly, fixedly or removably, on base 108 by inserting the end of main post 104 in the hole on base 108. A height adjusting, adjustable locking system 106, and/or by other mechanical means to raise and lower the head portion 102 or other portions of the invention 100 is useful to allow users of various heights to use the lacrosse training system 100 of the present invention. Also as shown in FIG. 1A, a plastic top structure 102 is rigidly, either fixedly, permanently or removably, attached at the top of main post 104, such as to resemble the head of the practice offensive player.
As also shown in FIG. 1A, one end of support rod 114 is attached rigidly on sheet metal body screen 110 at support hinge structure 210. In a preferred embodiment, sheet metal body screen structure 110 is a arc-shaped piece of sheet metal resembling a thin semi-circular wall that is suspended primarily by support rod 114. The other end of support rod 114 is attached rigidly and horizontally to main post 104 at a point that has the same vertical elevation of hinge structure 210, or higher or lower as may be a matter of design or manufacturing choice. The main purpose of support rod 114 and sheet metal body screen 110 is to provide horizontal support to the main post 104 during practice where users may assert lateral pressure to the whole lacrosse training system 100 of the present invention. Besides, sheet metal body screen 110 also represents the upper body of a player as hindrance/blockage to users when practicing check skills.
In a preferred embodiment, sheet metal body screen 110 also provides anchor points for two pull springs 112 and 113. As best shown in FIG. 2A, one end of pull springs 112 and 113 is attached rigidly to sheet metal body screen 110 by an eye hooks structure 116 for anchoring. The other ends of both pull springs 112 and 113 are connected together on either side of revolving arm 115 at the movable hinge structure 122, which mechanism is best shown in FIG. 2B. The mechanism of movable hinge structure 122 with the dual effects of pull springs 112 and 113 allow revolving arm 115 to revolve and oscillate radially around main post 104 in travel directions α and γ.
A practice opponent's lacrosse stick 120 is suspended essentially vertically and is attached flexibly at flexible wrist structure 118 to revolving arm 115. Lacrosse stick 120 can be any regular lacrosse stick such as those available commercially. Flexible wrist structure 118 is a rubber and/or spring structure that allows lacrosse stick 120 to sway and/or rotate in direction β essentially within a single given plane of space. The combined movement of α, γ and β resembles a player's movement during a lacrosse practice.
The entire lacrosse training system 100 of the present invention is manually actuated by rotating the revolving arm 115 in either directions α or γ. For instance, if revolving arm 115 is pushed backwards in direction α, in response pull spring 112 will be stretched and placed into greater tension. When user releases revolving arm 115 and/or lacrosse stick 120, pull spring 112 will try to return to its original length by pulling in at movable hinge structure 122. In response, revolving arm 115 will swing to the opposite direction γ and stretch the other pull spring 113. Due to the naturally dampening of kinetic movement of springs 112 and 113 and eventually stick 120, the whole process will repeat in ever-shortening oscillations until all energy is dissipated completely. While revolving arm 115 is rotating in oscillation, it will trigger rotation of lacrosse stick 120 in direction β. With the combination of movement of lacrosse stick 120 in both vertical and horizontal planes, it creates a random movement of lacrosse stick 120 and users can practice their checking skills and/or other lacrosse skills.
It will be understood by those skilled in the art that by providing greater or lesser spring constants, hinge tightness or damping devices, weights of components, etc., for the various components of the present invention, including springs 112 and 113, stick 120 or wrist hinge 118, etc., the period and amplitude of vertical and horizontal or other oscillation movements can be provided.
As shown in FIG. 2B, revolving arm 115 is coupled to revolving hinge structure 214 by mechanical means such as nuts and bolts. When revolving hinge structure 214 swings around the perimeter of main post 104, revolving arm 115, as an extension of revolving hinge structure 214, will swing in the same direction and angle.
FIG. 3 is a representative isometric view of another preferred embodiment of the lacrosse training system 300 of the present invention with a movable base system 308. As shown in FIG. 3, in a preferred embodiment, main post 104 is erected vertically and attached rigidly on movable base system 308. A movable base system comprises mainly a detachable base 304 and sled portion 306.
In a preferred embodiment, main post 104 is detachably or fixedly coupled to base portion 304 with a height adjustment, adjustable locking system 106 or similar. The purpose of the height adjustable locking system 106 is to allow users of various heights to use the lacrosse training system 100 of the present invention.
As shown in FIG. 3, detachable base portion 304 is secured on top of sled 306 by mechanical means such as nuts and bolts, or other attaching means such as welding. The purpose of sled portion 306 is to allow the entire lacrosse training system 100 of present invention to slide on a surface 98 when being pushed laterally or horizontally at the padded outer surface 302 of sheet metal body screen 110. Padded outer surface 302 is made of foam or similar padding materials available and is adhered to the outer surface of sheet metal body screen 110. The main purpose of padded outer surface 302 is to provide a sturdy and yet cushioned surface for people to exert horizontal push P on the lacrosse training system 100 of the present invention in order to slide the entire system in forward F direction. The additional dimension of movement and horizontal pressure P will make practicing with lacrosse training system 100 of present invention more challenging. Besides, users can practice pushing against a sturdy object as a simulation of actual checking play during a lacrosse game.
It will be understood that the angle of orientation between the upper screen 116 and padding portion 302, horizontal member 115, lacrosse stick 120 and the lower sled portion 306 can be adjusted so as to allow movement of the sled in any different direction.
FIG. 4 is a representative isometric view of another preferred embodiment of the lacrosse training system 400 of the present invention with a motorized oscillation system. In a preferred embodiment, the motorized oscillation system comprises a motor 402, a motion transmission tube 404 and an actuator 406. The main purpose of the motorized oscillation system is to eliminate frequent set-offs of lacrosse training system 400 of the present invention so the entire system 400 could be kept operating continuously.
As shown in FIG. 4, motor 402 is secured on main post 104 by any mechanical mean that is known in the art. Motor 402 is electrically powered by A/C and/or DC sources. The main function of motor 402 is to provide mechanical forces to activate actuator 406 and subsequently to keep revolving arm 115 swinging continually with and/or without pull springs 112 and 113.
Motion transmission tube 404 is an hollow or solid elongated structure with a preferably circular shape. The main function of motion transmission tube 404 is to transmit rotational motion generated by motor 402 to actuator 406. In a preferred embodiment, it could be achieved by a simple gears assembly or other mechanics that are known in the art. Rotational forces are then transferred to actuator 406 which is coupled with movable hinge structure 122, revolving arm 105 and pull springs 112 and 113. The actuator 406 will then provide mechanical forces to revolving arm 105 to keep it swinging periodically around main post 104. In a preferred embodiment, pull springs 112 and 113 help provide mechanical forces to revolving arm 115 as best shown and described in FIGS. 2A and 2B and/or define the degree of rotation of revolving arm 115.
FIG. 5 is a representative schematic view of a preferred embodiment of the method of use of the lacrosse training system 100 of the present invention. As shown in FIG. 5, user 500 and/or others sets off the lacrosse training system of the present invention by pulling revolving arm 115 to one side. Once the system 100 is “On”, both revolving arm 115 and lacrosse stick 120 will be oscillating along their respective plane of motion. As a result, lacrosse stick 120 appears to be moving in a random manner, resembling a lacrosse stick held by an offensive player. User 500, who is standing behind and/or on the side of the system 100, can then practice various checking skills and/or other lacrosse stick skills with the lacrosse training system 100 of the present invention until oscillations finally die down. User 500 could repeat the whole process by set off the system again.
Thus, in a preferred embodiment of the method of the present invention, the user 500 who is practicing his or her defensive moves, stands essentially in front of the upper screen portion 116 which is intended to simulate the shape, size and orientation of an offensiveman holding the ball in his or her cage 120. The screen portion 116 simulates the back of the offensiveman with the arch of the screen portion 116 simulating the curvature in the upper torso and extended arms which hold the handle of the lacrosse stick 120. Thus, as the net, basket or cage portion of the lacrosse stick 120 oscillates back and forth, oscillating either under kinetic or motorized energy, the user 500 can practice throwing “checks” around either side of the lacrosse training system 100 in an attempt to dislodge the ball from the lacrosse stick 120 of the training system 100.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. Although any methods and materials similar or equivalent to those described can be used in the practice or testing of the present invention, preferred methods and materials are now described. All publications and patent documents referenced in the present invention are incorporated herein by reference.
While the principles of the invention have been made clear in illustrative embodiments, there will be immediately obvious to those skilled in the art many modifications of structure, arrangement, proportions, the elements, materials, and components used in the practice of the invention, and otherwise, which are particularly adapted to specific environments and operative requirements without departing from those principles. The appended claims are intended to cover and embrace any and all such modifications, with the limits only of the true purview, spirit and scope of the invention.
