Stick for In-line Hockey {Stick for In-line Hockey}

The present invention relates to a stick used for inline hockey, and more specifically, by mounting a ball bearing with a smooth structure at the bottom of the stick, the ball moves smoothly regardless of the surface state of the floor so that you can enjoy inline hockey anywhere on a flat floor. A stick for inline hockey.

Inline Hockey or Roller Hockey literally means playing hockey on inline skates (or rollerblades), which is excellent in speed and maneuverability. It is leisure sports with wide interchangeability.

As the population of inline skating has exploded in recent years in Korea, it is now becoming a new sports event for the general public, and in the United States, Canada, Japan, and advanced foreign countries, ice hockey is a popular sport for men and women. It is also.

In-line hockey can be carried out regardless of the location with a flat bottom, but in practice, the stick and puck can be reduced in speed by the friction with the floor and the interest in the game can be halved. Likewise, the game was played only on the floor where the surface friction was low, while dribbling in ice hockey was done by holding the stick with one hand and pushing the puck on the ice, while in inline hockey with the stick held with both hands so that the stick did not touch the floor. Had to move the puck

Conventionally, in order to solve such a problem, silicon is attached to the lower end of the blade of the stick to reduce friction when contacting the bottom surface, but it is difficult to recognize the stick with silicon as a formal game equipment and can be applied for a long time. It was not a material, but a temporary solution.

The present invention devised to solve the above problems is to provide a stick for inline hockey that can be enjoyed in-line hockey regardless of the place by allowing the bottom of the stick to move freely without friction on the flat bottom surface. .

In addition, it is possible to easily handle the stick with one hand, so that the player can enjoy unnecessary physical strength, provide a stick for the inline hockey stick, which can add interest and at the same time make the progress of the game faster.

Therefore, there is an advantage in that the bottom end of the stick can be freely moved without friction on the flat bottom surface to enjoy in-line hockey regardless of the place.

In addition, the stick can be easily handled with one hand, which reduces the player's unnecessary physical strength, has the advantage of making the game faster, and adding interest.

And by providing the ball bearing of double pivot structure, it minimizes the friction between the rolling ball and the coupling element to improve the moving performance according to the rolling ball rotation, and it is not greatly affected by the rolling rotation by minute damage of the rolling ball. This has the advantage of reducing the cost and hassle.

The present invention by the configuration as described above will be described in detail with reference to the following drawings. 1 is a perspective view of a stick for inline hockey according to the present invention, Figure 2 is a longitudinal sectional view of the main portion of the stick for inline hockey according to the present invention, Figure 3 is a cross-sectional view of the main portion of the stick for inline hockey according to the present invention.

In-line hockey stick according to the present invention has a basic shape consisting of the shaft 20 and the blade 30 while mounting the ball bearing 10 of the structure smoothly rolling on the blade 30, the ball bearing rolling ball By the rotation of the (12) by the movement of the shaft 20 and the blade 60 coupled integrally with the ball bearing 10 is designed to be able to move smoothly even in contact with the bottom surface.

The shaft 20 and the blade 30 as a basic component of the inline hockey stick, according to the present known shape in the present invention will be described briefly.

The stick for inline hockey is composed of a straight shaft 20, which is a bag, and a blade 30 formed at a predetermined angle at the lower end of the shaft 20, using wood, aluminum, or plastic as an address material. The shaft 20 and the blade 30 are integrally formed or mutually separated so that the blade 30 having a shorter life than the shaft 20 can be replaced.

The ball bearing 10 installed in the present invention has the shield 11, the rolling ball 12, the retainer 13, and the auxiliary ball 14 as the main components, the rolling ball 12 and the rolling The auxiliary ball 14 is configured to interlock with the rolling ball 12 by inserting the auxiliary ball 14 in the space formed by the retainer 13 surrounding the ball 12.

The shield 11 forms an inner space for accommodating the rolling ball 12 which is the most basic component that provides rotational drive to the shaft 20 and the blade 30 to the lower end of the blade 30. By being fixed, it accommodates the rolling balls 12 and other components 13, 14 and at the same time determines the external design of the stick.

The shield 11 is installed along the longitudinal direction of the lower surface of the blade 30, a plurality of through-holes are formed in the lower end of the shield 30 along the longitudinal direction of the lower surface of the blade 30 is accommodated in the shield 11 Part of the rolling ball 12 is projected to the outside through the through hole.

The shield 11 is a basic skeleton that can firmly install the coupling components 172, 13, 14 with the rolling ball 12 therein, in addition to the through hole through which the rolling ball 12 protrudes. Blocks the path to the outside to prevent foreign matter from being inserted.

The rolling ball 12 is projected downward to the outside of the lower end of the shield 11 is located at the bottom end of the inline hockey stick according to the present invention is in point contact with the bottom surface, a plurality of blades are mounted along the longitudinal direction of the lower end of the blade ( 30) Even if the lower end touches the ground from various angles, it is configured to be easy to handle in that state.

The stick is free to move up, down, left, and right, not in a specific direction on the ground, and the force may be applied in various directions depending on the posture of the user, so that the rolling ball 12 is free to rotate and support loads in various directions. It is preferable to mount evenly across the bottom.

The ball bearing 10 is operated by the rolling of the rolling ball 11 on the ground, such as asphalt rough surface, and also on the smooth ground, such as marble, urethane, etc. in addition to the rolling of the rolling by the spherical protrusions.

When the user grips the shaft 20, the rolling ball 11 of the ball bearing 10 is in contact with the ground, and the stick is pushed freely on the ground by the rotation of the rolling ball 11 even in contact with the ground as described above It can be pulled, making it easy to hand the puck or ball anywhere on a flat surface.

The retainer 13 surrounds the entire outer surface of the rolling ball 12 accommodated in the shield 11 and is fixed to the lower end of the shield 11 to form an upper limit of the rolling ball 12. When the downward pressure is applied to the rolling ball 12 is prevented from being separated into the inner space on the lower end of the shield (11).

The retainer 13 is formed in an empty hemispherical shape to accommodate the upper side of the rolling ball 12 therein, formed to have a radius of curvature larger than the rolling ball 12 to the rolling ball 12 When accommodated in the retainer 13 to achieve a predetermined distance from the retainer 13.

An auxiliary ball 14 is inserted into a space formed by the spacing between the rolling ball 12 and the retainer 13, and the auxiliary ball 14 is formed with the rolling ball 12 and the retainer 13. Many are inserted to fill the entire space.

When the rolling ball 12 receives the weight of the stick and the downward pressure of the user, the lower portion of the rolling ball 12 exposed to the outside of the shield 11 is in point contact with the bottom surface, and the inside of the shield 11 The upper portion accommodated is in point contact with the plurality of auxiliary balls 14 accommodated in the retainer 13.

The auxiliary ball 14 sandwiched between the retainer 13 and the rolling ball 12 subjected to the downward pressure is the cloud in the point contact state to minimize the friction area between the rolling ball 12 and the retainer 13. Rolling or sliding in conjunction with the rotation of the ball 12 to minimize the shear friction also when the rotation of the rolling ball 12 is generated only a minimum friction between the retainer (13).

The retainer 13 has a plurality of hemispherical grooves formed on the inner circumference to accommodate a part of the auxiliary ball 14 so that the auxiliary ball 14 is accommodated in each hemispherical groove and the rolling ball 12 ), Even if the rolling ball 12 is rotated, the auxiliary ball 14 is fitted into the receiving groove to roll only at a specific position.

In the structure of the retainer 13 as described above, the auxiliary ball 14 is sloped to one side according to the rotation of the rolling ball 12 and the movement of the blade 30, or provides a uniform contact area to the cloud ball 12. In order to prevent the exhaust ball from filling the entire space with the auxiliary ball 14, but the friction area between the retainer 13 and the auxiliary ball 14 is expanded, rolling and sliding of the auxiliary ball 14 Since the movement may not be performed smoothly, it is preferable to apply a suitable structure according to the floor surface or the level of the game.

Until now, in-line hockey games had to move the body and puck only by lifting with two hands to prevent the stick from touching the floor, as the bottom surface was not as smooth as ice. It can be easily handled, reducing unnecessary physical consumption of the user, and also contributes to the popularization of inline hockey by additionally generating interest in the fast pace of the game.

The inline hockey stick according to the present invention has a double pivot structure using the rolling ball 12 and the auxiliary ball 14, so that the friction between the rolling ball 12 and the retainer 13 is smooth even on the bottom surface. It is relatively sufficiently smaller than the friction of the rolling ball 12 is made to smoothly have a more expanded coverage and improved mobility than the conventional in-line hockey stick.

The double pivot structure reduces fatigue due to repeated friction and impact between the rolling ball 12 and the retainer 13 to improve fatigue life, and the rolling ball 12 is minutely rotated by the rotation of the auxiliary ball 14. Since the damage may be sufficiently mild, minute damage does not significantly affect the rotation of the rolling ball 12, thereby improving the life of the entire bearing structure.

The present invention by the above configuration has the effect of allowing the stick lower end to move freely without friction on the flat bottom surface to enjoy inline hockey regardless of place.

In addition, the stick can be easily handled with only one hand, reducing unnecessary physical consumption of the player, allowing the game to proceed quickly and adding other interests.

In addition, the ball bearing has a double pivot structure, which minimizes the friction between the rolling ball and the coupling element, and improves the moving performance due to the rolling ball rotation. There are other effects that reduce the cost and hassle.
