Description

An improved club head

technical field

The present invention relates to an improved stick head for use with a stick for sports such as field hockey or indoor floor hockey to improve dribbling.

technical background

The past few decades have seen unprecedented technological advancements in stick sports. For example, new lightweight sticks made of carbon fiber material can be combined with new improved club heads. Moreover, new materials that are lighter in weight but allow the user to grip the club better are constantly being developed. Today, players who use a stick must be equipped with the proper equipment in order to perform at their best.

Sports using sticks have been popular for a long time, whether as competitive or purely recreational. Strict rules have been established in the field of competitive sports to regulate the sports equipment that athletes are allowed to use and the appearance that such sports equipment is required to have. These rules ensure that no athlete gains an unfair advantage over an opponent during a match. The strict rules established to ensure fair play in indoor floor hockey, field hockey and similar sports have also contributed to the levelling of technical development, which means that these rules have hindered the development of sports using the stick .

A solution proposed to improve the stick head under the framework of existing rules is the patent GB2,318,064. In this patent, the clubhead includes a cross-section relative to the shaft, wherein the cross-section is designed for better ball control during dribbling. In the patent WO 97/28854, a club head of an indoor hockey stick is disclosed, wherein a vertical surface relative to the stick is arranged on the front of the club head, which can improve the accuracy of shooting and facilitate dribbling.

Previous development efforts have focused on developing new clubs, heads and shafts that can be used in the game, ie those improved designs are within the existing regulations. The regulatory framework and many commercial factors behind getting a piece of sporting equipment approved for competition make it often difficult to develop and popularize new sports. Generally speaking, it can be said that the direction of technology development has been to create lighter clubs and develop club heads that can enhance the dribbling performance or ball control performance of the club. A classic example of the need for full ball control is the dribbling style known as "Zorro" in indoor floor hockey. The "Zorro" dribble requires players to pick up the ball with a stick to the head of the stick and then move the stick through the air with great speed and precision while the ball stays attached to the head of the stick. This allows skilled players to perform very difficult moves while keeping the ball on the stick. This way, a player can dribble past an opponent without the ball touching the ground.

However, shooting performance and dribbling performance always seem to be incompatible with each other, that is, if the dribbling performance is developed, the shooting performance will be reduced, and vice versa.

An example of this development is given in US Patent 5,810,684, which describes a head for an indoor floor hockey stick. This stick head design includes one or two holes to facilitate shot control and dribbling. The holes extend along the entire length of the stick head thickness and are perpendicular thereto. When shooting, the ball slides along the indented portion of the stick head in order to reach the hole where, according to what is disclosed, the best shot control will be obtained. Therefore, this hole is mainly designed to be suitable for controlling the position of the ball when it leaves the club head. The hole (or both) in the club head is therefore designed to have some face, behind the ball, that allows sufficient force to be transferred from the ball to the club. By this design, the disclosed stick achieves a compromise between shot control and dribble control without significantly improving the desired better shot control and dribble control.

Patent EP 0427522 describes a club that goes beyond the aforementioned regulatory framework. This patent discloses a paddle-shaped racing device, wherein the paddle comprises a central disc and two peripheral regions, either hollow or a recessed portion, for receiving projectiles such as balls. The size of the hole roughly matches the size of the projectile. However, such playing devices do not provide the desired overall ball control. In addition, it is difficult for players experienced in the sport with sticks to enjoy using such a game device, since it differs greatly from the aforementioned clubs used within the framework of current regulations.

The present invention aims to address at least some of the above-mentioned problems. So it seemed possible to develop a club head that would improve ball control while dribbling. There is also a need for a club head that achieves good dribbling without compromising shooting performance.

Contents of the invention

The present invention at least partially solves the foregoing and other problems by providing a head for use with, for example, an indoor floor hockey or hockey stick, wherein the head includes a hole for holding the ball during dribbling. Specifically, the club head includes additional means for connecting the stick to the substantially elongated club head, the club head includes a first surface and a second surface, the surface is surrounded by an upper longitudinal edge, a lower longitudinal edge and a first short length. The side and the second short side, the first surface and the second surface include a shooting surface, a dribbling surface and at least one ball hole. The hole includes at least one suitable diameter to allow the hole to hold the ball both on the ground and in the air.

According to one embodiment of the present invention, the dribbling performance of the club head provides a unique combination of ground dribbling and air dribbling. The simple nature of dribbling in the air, the ability to perform difficult moves in the air with a stick attached to the ball, also makes the invention well suited for goals other than traditional goals. For example, a goal similar to a basket in basketball can be used as a goal applicable to the present invention. The clubhead grip provided by the present invention makes it possible to dribble in the air and putt the ball from all angles in ways that were heretofore impossible. Unique aerial maneuvers and aerial dribbles can be accomplished using a club equipped with a club head according to the present invention within the framework of existing game rules using the club head and ball in sports such as indoor floor hockey. Impossible with a stick. Furthermore, the holes allow both sides of the club head to catch and hold the ball. Thus, if the ball is placed in the ball hole of the present invention, the user is not hitting the ball but pushing the ball to shoot, and the shooting surface and the dribbling surface can also be used as the traditional shooting surface and the dribbling surface simultaneously. This combination makes the present invention all have good shooting power and dribbling performance in ground dribble and air dribble process.

The hole may also include a circular cross-section having an inner diameter sized to retain a ball in said hole during ground dribbles and aerial dribbles. The present invention provides users with very good ball control ability in the process of dribbling, and even inexperienced users can use the club with the middle head of the present invention to complete very difficult aerial dribbles. In addition, an aerial pass can be easily caught with the stick head of the present invention.

In another embodiment of the present invention, the ball hole sequentially includes a scoring surface and a spherical exit surface, the scoring surface includes a goal diameter, and the spherical exit surface includes a ball exit diameter, wherein the inner diameter is located between the scoring surface and the exit surface, And wherein said inner diameter is smaller than said ball hole said ball diameter and ball exit diameter. This configuration of the ball hole ensures good control of the ball when it rests, for example, between the inner diameter and the inner face or between the inner diameter and the outer face.

The hole can be adjusted to the shape of a ball by what may be called a spherical surface which is between the spherical surface and the inner diameter and which is characterized by a substantially concave surface. This allows the hole to hold the ball in an enveloping fashion, further enhancing dribbling performance. The spherical surface between the outgoing spherical surface and the inner diameter may also have substantially concave features. The club head is more practical because both sides can be used to catch the ball. The concave character of the spherical surface means that the shape of the spherical surface between the spherical surface and the inner diameter and the spherical surface between the outgoing surface and the inner diameter substantially conforms to the shape of a ball.

In one embodiment of the invention, the shape of the spherical surface substantially conforms to the shape of a sphere. In one embodiment of the present invention, the ball may be made of a material other than the material from which the head is made to provide the ball with certain desired properties, such as increased friction, improved vibration dampening, and the like.

The circular cross-section of the hole allows for a better fit between the ball and the clubhead, allowing for more difficult dribbles - even for less experienced stick players. These properties can be further enhanced by the round hole's scoring and delivery surfaces.

In an alternative embodiment of the present invention, the club head includes a first or second short side having a section of curvature along at least a portion of the first or second short side and the circle of the scoring and exiting surfaces. The shape is consistent. Such a club shape saves material and gives the user the impression of a traditional club.

The hole is preferably located adjacent either the first short side or the second short side of the club head, and when the attachment is located adjacent the first short side, the hole is preferably located adjacent the other short side. In addition, the shooting surface and the dribbling surface on the first surface and the second surface may have a concave shape. This shape facilitates the use of the entire shooting surface and dribbling surface to guide the ball into the hole. Therefore, no matter where the user catches the ball on the shooting surface or the dribbling surface during the passing process, the user can easily send the ball into the ball hole for dribbling or shooting.

The lower edge includes a groove extending along at least a portion of the length of the lower edge. This groove saves material and at the same time, in certain embodiments of the invention, this groove provides a wide lower longitudinal side with a minimum consumption of material. In one embodiment, the upper edge may be concave and the lower edge may be convex, so that said club head acquires a substantially elongated curved shape.

The club head of the present invention makes it possible for inexperienced users to perform superb dribbling and unique aerial moves. Therefore, games played with a stick equipped with the present invention tend to have very high stick positions and shots in the air. The result is that the player's hand may be vulnerable to being hit by the club. One embodiment of the present invention therefore comprises a rod mounted on the head attachment and fitted with guards. The guard can be made from the same material as the rod or from a different material. Preferably, the guard is mounted on the side of the rod, extending in a circumferential manner along the transverse perimeter of the rod body, in a manner similar to the hand guards on Japanese knives. The guard is preferably mounted in such a way that it is convenient to grasp the shaft with two hands so that a sufficiently high momentum can be achieved when the ball is pushed out.

Furthermore, the invention comprises a ball and a club head suitable for the ball as claimed in claim 1 . In order to make them match better to ensure good ground and air dribble performance, the inner diameter of the ball hole (Φ _i ) is preferably 75%-99.9% of the ball diameter, more preferably 80%-99% of the ball diameter , most preferably 85%-99% of the ball diameter.

The invention also relates to a club comprising a shaft and an elongated head mounted to the shaft by attachment means. The club head includes a first surface and a second surface surrounded by upper and lower longitudinal edges and first and second short sides. The first surface and the second surface include a shooting surface and a dribbling surface and at least one through hole, wherein the hole extends between the first surface and the second surface of the club head. The hole is a ball hole, wherein the hole includes at least one diameter adapted to retain the ball in the hole during ground dribbles and aerial dribbles.

Preferably, there is also a ball used in conjunction with the club, wherein the ball hole of the club head is suitable for the ball. Preferably, the ball and the club constitute a set of equipment.

Detailed ways

The present invention will be described in more detail through examples below.

Figure 1 shows a club head 10 according to one embodiment of the present invention. The club head 10 has a substantially elongated shape comprising a first surface 11 and a second surface 12 surrounded by an upper longitudinal edge 13 and a lower longitudinal edge 14 and a first short side 15 and a second short side 16 respectively. Included in said first surface 11 and second surface 12 are a shooting surface 16 and a dribbling surface 17 which in this exemplary embodiment comprise a substantially concave surface. The concave surface may also be straight or, in a less preferred embodiment, also convex. Furthermore, the first surface 11 and the second surface 12 may include a plurality of through air holes 18, so as to minimize the air resistance on the stick head when using the stick to shoot a goal or pass a ball to a teammate. The plurality of air holes 18 therethrough also make the club head lighter and thus the club lighter. Furthermore, an attachment means 19 is connected to the upper longitudinal edge 13 and the first short side 15 of the club head. An add-on can be attached to the club. The club may also be fitted with a guard (not shown). The attachment can be in the form of a cylindrical tube with a hole into which the club can be inserted and thus connected to the club head 10 . As an alternative, the attachment can also be of any other conventional form, ie can comprise a plane on which it can be fixed to the club, for example with screws or the like.

The slightly convex lower longitudinal edge 14 extends in a curve to the first short side 15 and then terminates in an attachment 19 . Starting from the attachment 19 , the upper longitudinal edge 13 extends in a concave curve towards a second short side 16 which follows a semicircular curve and then meets the lower longitudinal edge 14 . The club head 10 therefore has substantially a curved shape. Of course, it is within the scope of the present invention for the upper longitudinal edge 13 and the lower longitudinal edge 14 to be straight or angled. The first short side 15 and the second short side 16 may also be straight or angled.

A ball hole 20 for holding the ball during ground and air dribbles is located on the first surface 11 and the second surface 12 . Ball hole 20 is circular in Fig. 1, and has the ball surface 21 that comprises goal diameter Φ _id and the ball exit surface 22 that comprises ball exit diameter Φ _ud , and wherein has the goal surface 21 of goal diameter Φ _id to be positioned at stick. On the first surface 11 of the head, and a ball-out surface 22 with a ball-out diameter Φ _ud is located on the second surface 12 of the club head. In Fig. 1, the goal diameter Φ _id and the ball exit diameter Φ _ud are equal, but they may also be different, that is, the ball hole 20 may also be designed so that the goal surface and the exit surface are different. In the exemplary embodiment, the scoring surface 21 and the spherical exiting surface 22 are circular, but they may also be of other shapes, such as elliptical or elliptical-like. Moreover, the ball hole 20 includes an inner diameter Φ _i between the scoring surface 21 and the exiting surface 22 , and the inner diameter Φ _i is smaller than the stated entering diameter Φ _id and the exiting diameter Φ _ud . In the process of dribbling, the ball is mainly kept in the ball hole by the inner diameter Φ _i . However, in certain preferred embodiments, a goal face 21 having a goal diameter Φ _id and an exit face 22 having a ball exit diameter Φ _ud help keep the ball in place.

The ball hole 20 can be positioned near the other short side 16 as shown in FIG. The semicircular short side 16 is defined. However, it is also within the scope of the present invention to place the eyelet 20 near the first short side 15, or alternatively, to place the eyelet 20 in the middle of the club head 10.

In one embodiment of the present invention, the ball hole's ball-going surface 21 and ball-going surface 22 are offset relative to the center point Φ _i mp and the inner diameter Φ _i . Fig. 1 shows how the scoring surface 21 and the exiting surface 22 of the ball hole are offset with respect to the inner diameter Φ _i , so that the position of the center point Φ _i mp on the inner diameter Φ _i is larger than the goal diameter Φ _id and the exiting ball The center point mp on the diameter Φ _ud is closer to the first short side of the stick head. This offset is represented in FIG. 1 as the distance S along the longitudinal centerline M of the club head. However, this offset does not have to be along the longitudinal centerline M, but can also be located at an angle away from said longitudinal centerline M. The length of the distance S is preferably between 1-25mm, more preferably between 1-20mm, most preferably between 2-15mm. This offset gives the hole a special shape that allows the user to easily pick up the ball through the head of the stick. This feature becomes especially important when the user is running towards the ball and picking it up while running.

Figure 2 shows a perspective view of a portion of a club with club head 30 in a horizontal position, according to one embodiment of the present invention. The club head 30 comprises a substantially elongated shape comprising a first surface 31 and a second surface 32 surrounded by an upper longitudinal edge 33 and a lower longitudinal edge 34 and a first short side 35 and a second short side 36 respectively. Included in said first surface 31 and second surface 32 are a shooting surface 36 and a dribbling surface 37 which in the exemplary embodiment comprise a substantially concave surface. The concave surface may also be straight or, in a less preferred embodiment, also convex. Furthermore, the first surface 31 and the second surface 32 may include a plurality of air holes 38 therethrough so as to minimize the air resistance experienced by the stick head when using the stick to shoot a goal or pass a ball to a teammate. The plurality of air holes 38 therethrough also makes the club head lighter and thus the club lighter. Furthermore, an attachment means 39 is connected to the upper longitudinal edge 33 and the first short side 35 of the club head. An add-on can be attached to the club. The club may also be fitted with a guard (not shown). The attachment may be in the form of a cylindrical tube with a hole through which the club can be inserted to connect to the club head 30 . As an alternative, the attachment can also be of any other conventional form, ie can comprise a plane on which it can be fixed to the club, for example with screws or the like.

In addition, ball passing holes 40 for holding the ball during dribbling on the ground and in the air are located on the first surface 31 and the second surface 32 . The ball hole 40 shown in the figure is a circular ball hole and has a goal surface 41 and a ball exit surface 42, the goal surface 41 has a goal diameter Φ _id , and the ball exit surface 42 has a ball exit diameter Φ _ud . A scoring surface 41 with a goal diameter Φ _id is located on the first surface 31 of the club head, while a delivery surface 42 with a delivery diameter Φ _ud is located on the second surface 32 of the club head. In the exemplary embodiment, the scoring surface 41 and the spherical exiting surface 42 are circular, but they may also be of other shapes, such as oval or similar. In addition, the ball hole 40 includes an inner diameter Φ _i located between the goal surface 41 and the ball exit surface 42 , and the inner diameter Φ _i is smaller than the aforementioned goal diameter Φ _id and ball exit diameter Φ _ud . During dribbling, it is mainly the inner diameter Φ _i that keeps the ball in the ball hole. However, in certain preferred embodiments it is also possible to use the goal diameter Φ _id and the exit diameter Φ _ud to hold the ball.

The groove 43 extending at least along the lower longitudinal edge 34 makes it possible to save manufacturing material and obtain a wide lower longitudinal edge 34 . The groove 43 continues onwards onto at least a portion of the first short side 35 . The wide lower longitudinal edge 34 makes it easy to lift the ball with the stick to place the ball in the hole 40 for dribbling with the stick and making superb aerial moves - so-called "Zorros" action. Preferably, the width of the lower longitudinal edge 34 is between 5-40 mm, more preferably between 5-25 mm. Preferably, the width of the lower longitudinal edge 34 extends upwardly onto the second short side 36 such that the second short side 36 is equal in width to the lower longitudinal edge 34 . Preferably, the second short side 36 narrows as it transitions into the upper longitudinal edge 33 .

In another embodiment of the present invention, the shooting surface 36 and the dribbling surface 37 have a substantially concave shape. The concave shape means that the head 30 is thinner in the middle of the head than at the upper and lower longitudinal edges 33,34. In this embodiment, the entire shooting surface 36 and dribbling surface 37 act as guide channels for the ball to enter the ball hole 40, which is an improvement over the prior art. Since the entire shooting surface 36 and the dribbling surface 37 act as a guide channel leading to the ball hole 40, the ball can, for example, be caught in the air with the entire shooting surface 36 and the dribbling surface 37, and then be guided to the ball hole 40. Thus, this embodiment of the invention facilitates the "zorro" maneuver for players who are not used to catching the ball with a stick.

FIG. 3 shows a cross-section of the club head 30 along the line AA. The figure shows a hole 40 comprising a goal surface 41 with a goal diameter Φ _id , an inner diameter Φ _i , and a ball exit surface 42 with a ball exit diameter Φ _ud . Furthermore, a part of the first surface 31 and the second surface 32 , a part of the upper longitudinal edge 33 and the lower longitudinal edge 34 , the interior of the other short side 36 , and the groove 43 shown in FIG. 2 are also visible. Between the goal surface 41 and the inner diameter Φ _i there is a first spherical surface 45 and between the exit surface 42 and the exit diameter Φ _ud there is a second spherical surface 46 . Surfaces 45 and 46 help reduce ball vibration and hold the ball when the hole receives the ball, for example, during a pass or catch in the air. The spherical surfaces 45 and 46 may be concave as shown in the exemplary embodiment to better retain the ball in the ball hole 40 . The concavities on the spherical surfaces 45 and 46 can surround the ball and provide a better grip for holding the ball. Preferably, the concave spherical surfaces 45 and 46 match the shape of the ball. In one embodiment of the present invention, spherical surfaces 45 and 46 comprise a different material than club head 30 . For example, spherical surfaces 45 and 46 may be covered with a material that is softer than the material from which club head 30 is made. For example, the spherical surfaces 45 and 46 may be covered with a foam material, such as polyurethane, so as to make the surface soft and provide high friction so that the ball can be easily retained in the ball hole 40 .

In another embodiment of the present invention, the present invention includes a ball having a diameter smaller than the in-ball diameter Φ _id and the ball-out diameter Φ _ud of the club head, but larger than the inside diameter of the club head Φ _i . This embodiment makes it possible to catch the pass relatively easily with the hole.

The stick head of the present invention is mainly made of plastic materials, especially thermoplastic materials, such as polypropylene, polyethylene, polyurethane, polytetrafluoroethylene, polystyrene, polyamide, polyester, polysiloxane, polybutylene dienes or their compounds. It is preferably manufactured using compounds containing HDPE (High Density Polyethylene) or HDPP (High Density Polypropylene). In order to obtain a good use effect through the use of materials, the weight of the stick head in the present invention should be about 40-300 grams, preferably between 50-200 grams, most preferably 50-150 grams. Of course, within the scope of the invention, wood or other metal materials can also be used to make the club head, even if these materials are generally not as good as the above-mentioned materials.
