Description

Head unit of a delivery stick for wheelchair curling

[0001] The present invention relates to a head unit of a delivery stick for wheelchair curling, and more particularly, to a head unit of a delivery stick for wheelchair curling that not only stably supports a curling stone to enable accurate throwing of the curling stone, but also adjusts the amount of spin transferred to the curling stone by adjusting the position of a connecting portion connecting the delivery stick and the head unit.

[0002]

[0003] Wheelchair curling is a sport designed to allow athletes with limited physical mobility to enjoy the sport. Players ride in wheelchairs and slide a curling stone across the ice, aiming to score points by sliding it into a target. While wheelchair curling shares similar rules and scoring with the more common winter sport of curling, it differs in certain aspects, such as the use of assistive devices and the length of the game. Typically, wheelchair curling uses a delivery stick (or extender cue) to deliver the stone.

[0004] A delivery stick is an assistive device used by a player in a wheelchair to throw a curling stone. The delivery stick connects the player's body to the curling stone, helping the player aim and throw the stone accurately.

[0005] FIG. 1 is a reference diagram for explaining a prior art. Referring to FIG. 1, a head (30) is coupled to the end of a delivery stick (10) to connect the handle (25) of a curling stone (20) and the delivery stick (10) to transmit the force transmitted through the delivery stick (10) to the curling stone (20).

[0006] The head (30) of the delivery stick (10) according to this conventional technology had a problem in that the position of the connecting part (35) connected to the delivery stick (10) was fixed, making it difficult to control the amount of spin transmitted to the curling stone (20).

[0007] In addition, a bend (37) is formed on the head (30) to stably support the handle (25), but due to this bend (37), a phenomenon may occur in which the bend (37) of the head (30) gets caught on the handle (25) when the curling stone (20) is thrown, and as a result, the handle (25) cannot be naturally separated from the head (30) when throwing, causing the throwing direction of the curling stone (20) to become distorted, resulting in a problem in which the accuracy of throwing decreases.

[0008]

[0009] The present invention is intended to solve the above problems, and provides a head unit of a delivery stick for wheelchair curling that not only stably supports a curling stone to enable accurate throwing of the curling stone, but also adjusts the amount of spin transferred to the curling stone by adjusting the position of a connecting portion connecting the delivery stick and the head unit.

[0010] In addition, a head unit of a delivery stick for wheelchair curling is provided that can improve the stability of throwing a curling stone and the accuracy of the throwing direction by allowing the handle of the curling stone to naturally separate from the head unit when throwing the curling stone.

[0011]

[0012] In accordance with the above purpose, the present invention provides a head unit of a delivery stick for wheelchair curling, characterized in that it is a head unit coupled to a delivery stick used for throwing a curling stone, comprising: a base body mounted on an upper surface of the curling stone; a holder that supports a handle of the curling stone and is provided on the base body to be movable in a first direction; and a connecting column coupled to the delivery stick and rotatably provided on the holder.

[0013] At this time, the base body may include a first support portion formed in a streamlined shape to support a connecting portion of the handle; a second support portion formed symmetrically to the first support portion and spaced apart from the first support portion; and a bridge portion connecting the first support portion and the second support portion and having the holder movably provided.

[0014] At this time, the holder may further include a holder body part through which the bridge part is inserted and moves in a first direction along the bridge part; and a holder extension part formed to extend on an upper surface of the holder body part and having a grip surface corresponding to the outer circumference of the handle.

[0015] At this time, a guide surface may be extended and formed on the lower part of the above-mentioned surface to guide separation of the handle when the curling stone is thrown.

[0016] Meanwhile, a screw groove is formed on the upper surface of the holder extension, a connecting hole communicating with the screw groove is formed in the connecting column, and a bolt penetrating the connecting hole and screw-connected with the screw groove may be further included.

[0017] At this time, a first magnetic body is provided on the upper surface of the holder extension, and a second magnetic body corresponding to the first magnetic body is provided on the connecting column, so that the holder and the connecting column can be magnetically coupled.

[0018] In addition, the bridge portion may further include a slide portion in which a plurality of first gear portions are formed along a first direction, the slide portion is provided on the holder body portion so as to be movable along a second direction perpendicular to the first direction, and a second gear portion corresponding to the first gear portion is formed inside, and as it moves, the second gear portion is fastened to the first gear portion to fix the holder body portion to the bridge portion; and an elastic body provided between an end of the slide portion and an inner wall of the holder body portion to elastically support the slide portion.

[0019]

[0020] Accordingly, the present invention not only stably supports a curling stone to enable accurate throwing of the curling stone, but also has the effect of controlling the amount of spin transmitted to the curling stone by controlling the position of the connection part connecting the delivery stick and the head unit.

[0021] In addition, there is an effect that can improve the stability of throwing the curling stone and the accuracy of the throwing direction by allowing the handle of the curling stone to naturally separate from the head unit when throwing the curling stone.

[0022]

[0023] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0037]

[0038] Hereinafter, with reference to the attached drawings, a head unit of a delivery stick for wheelchair curling according to a preferred embodiment of the present invention will be described.

[0039]

[0040] The head unit (10) (hereinafter, 'head unit (10)') of the delivery stick (30) for wheelchair curling according to the present invention is coupled to a delivery stick (30) (extender cue) for delivering a curling stone (20) during a wheelchair curling game, so that a user can easily throw the curling stone (20). Specifically, the user holds the delivery stick (30) while sitting on the wheelchair, places the head unit (10) coupled to the end of the delivery stick (30) on the curling stone (20), aims the curling stone (20) in a desired direction, and pushes the delivery stick (30) to throw the curling stone (20). At this time, the curling stone (20) is separated from the head unit (10) by the user's throwing, and the curling stone (20) that has detached from the head unit (10) slides and moves on the ice.

[0041]

[0042] Hereinafter, the head unit (10) of the delivery stick (30) for wheelchair curling according to the present invention will be described with reference to FIGS. 2 to 7.

[0043]

[0044] FIG. 2 is a schematic diagram of a head unit (10) of a delivery stick (30) for wheelchair curling according to the present invention, and FIG. 3 is an exploded perspective view of a head unit (10) of a delivery stick (30) for wheelchair curling according to the present invention. Referring to FIGS. 2 and 3, the head unit (10) according to the present invention may include a base body (100), a holder (200), and a connecting column (300).

[0045] The base body (100) is mounted on a curling stone (20) and supports the curling stone (20), the holder (200) supports the handle (25) of the curling stone (20) and is provided on the base body (100) to be movable in a first direction, and the connecting column (300) is coupled to the delivery stick (30) and is provided on the holder (200) to be rotatably connected.

[0046] In the present invention, the first direction means the longitudinal direction of the handle (25) (the longitudinal direction of the bridge portion of the base body to be described later), and the second direction means a direction perpendicular to the first direction.

[0047] The base body (100) may include a first support portion (110), a second support portion (120), and a bridge portion (130).

[0048] The first support member (110) is formed in a streamlined shape and supports the connecting member (27) of the handle (25). Specifically, the lower surface of the first support member (110) is fixed to the upper surface of the curling stone (20), and a streamlined curved portion is formed on the outer surface, so that the curved portion comes into contact with the connecting member (27) of the handle (25) of the curling stone (20) and supports the connecting member (27).

[0049] The second support part (120) is formed to be symmetrical to the first support part (110) and is spaced apart from the first support part (110). Specifically, the second support part (120) is formed to be symmetrical to the first support part (110) and is spaced apart from the first support part (110) at a predetermined distance, the lower side is placed on the upper side of the curling stone (20), and a streamlined curved part is formed on the outer side. In the present embodiment, the curved part of the first support part (110) is described as being in contact with the connecting part (27) of the handle (25) to support the connecting part (27), but conversely, the curved part of the second support part (120) may be in contact with the connecting part (27) of the handle (25) to support the connecting part (27).

[0050] The bridge portion (130) connects the first support portion (110) and the second support portion (120). The bridge portion (130) is formed in a bar shape with a constant length, and one end is connected to the inner surface of the first support portion (110), and the other end is connected to the inner surface of the second support portion (120), thereby connecting the first support portion (110) and the second support portion (120). Specifically, fixing portions (131) are formed protrudingly at both ends of the bridge portion (130), and fixing grooves (111, 121) are formed on the inner surface of the first support portion (110) and the inner surface of the second support portion (120), respectively, and the fixing portions (131) are inserted into the fixing grooves (111, 121), thereby connecting the first support portion (110) and the second support portion (120).

[0051] At this time, the bridge part (130) may be provided with a holder (200) that can move in a first direction. The bridge part (130) may be positioned by penetrating and inserting the holder (200), and the holder (200) is provided in the bridge part (130) so as to be able to move in the first direction (the longitudinal direction of the bridge part (130). The amount of spin applied to the curling stone (20) when the curling stone (20) is thrown can be adjusted by the holder (200) that is provided in a movable manner in the bridge part (130). That is, the connecting column (300) fixed to the delivery stick (30) is connected to the holder (200), and the force applied by the user through the delivery stick (30) is transmitted to the holder (200) through the delivery stick (30) and the connecting column (300), so that the amount of spin applied to the curling stone (20) can be adjusted depending on where the holder (200) is located on the curling stone (20) with respect to the connecting portion (27) of the handle (25). In the case of the present invention, the holder (200) is provided to be movable on the bridge portion (130), so that the position of the holder (200) on the curling stone (20) can be adjusted while the first support portion (110) supports the connecting portion (27) of the handle (25). Accordingly, the present invention can maintain a state in which the base body (100) that is placed on the curling stone (20) when pitching is in contact with the connecting portion (27) of the handle (25), thereby stably supporting the curling stone (20) when pitching and simultaneously controlling the amount of spin of the stone curling.

[0052] Meanwhile, the holder (200) may include a holder main body (210) and a holder extension (230).

[0053] The holder main body (210) has a bridge part (130) inserted therethrough and moves in a first direction along the bridge part (130). The holder main body (210) has a first through hole (213) formed therein that penetrates the inside in the first direction, and the bridge part (130) is inserted into the first through hole (213) so that the holder main body (210) moves left / right along the bridge part (130). At this time, the lower surface of the holder main body (210) is placed on the upper surface of the curling stone (20).

[0054] The holder extension part (230) is formed to extend upwardly on the upper surface of the holder body part (210), and a grip surface (231) corresponding to the outer circumference of the handle (25) is formed. Specifically, the holder extension part (230) is formed to be connected to the upper surface of the holder body part (210), a connection column (300) is connected to the upper surface of the holder extension part (230), and a hemispherical grip surface (231) is formed on the inner surface to correspond to the outer circumference of the handle (25). The grip surface (231) of the holder extension part (230) is a part that grips and supports the handle (25) of the curling stone (20) when the head unit (10) is placed on the curling stone (20), and is formed in a hemispherical shape to stably support the handle (25) when throwing the curling stone (20), thereby enabling accurate throwing.

[0055] According to this embodiment, the grip surface (231) of the holder extension (230) grips the handle (25) of the curling stone (20), and the first support portion (110) and the second support portion (9120) support the connection portion (27) of the handle portion (25), so that the head unit (10) stably supports the curling stone (20), thereby enabling accurate throwing of the curling stone (20).

[0056] Meanwhile, a guide surface (233) may be formed to extend from the lower end of the grip surface (231) to guide the separation of the handle (25) when the curling stone (20) is thrown. Specifically, the grip surface (231) is formed in a hemispherical shape, and the lower end of the hemispherical grip surface (231) is formed to be long along the upper surface of the holder body (210), so that the lower end of the grip surface (231) is formed to be longer than the upper end.

[0057] When a curling stone (20) is thrown, the handle (25) of the curling stone (20) is separated from the grip surface (231) of the holder (200), causing the curling stone (20) to detach from the head unit (10) and slide on the ice. According to the present embodiment, the guide surface (233) connected to the grip surface (231) is formed long so that the handle (25) of the curling stone (20) that is separated from the grip surface (231) when thrown slides along the guide surface (233), thereby guiding the separation of the handle (25), thereby improving the directionality of the curling stone (20), thereby increasing the directionality and accuracy of throwing.

[0058] Meanwhile, the head unit (10) according to the present embodiment may be provided with a screw groove (235) formed on the upper surface of the holder extension (230), a connecting hole (305) communicating with the screw groove (235) formed in the connecting column (300), and a bolt (310) that penetrates the connecting hole (305) and is screw-connected with the screw groove (235).

[0059] The bolt (310) penetrates the connecting column (300) and is coupled with the holder extension (230) of the holder (200), thereby connecting the connecting column (300) and the holder (200). At this time, the bolt (310) may be coupled to the screw groove (235) with a space so that the connecting column (300) can rotate left / right and hinge up / down with respect to the holder extension (230). At this time, the bolt (310) may be provided with a plurality of washers (311) to prevent loosening of the bolt (310) due to rotation and hinge movement.

[0060] FIG. 4 is a reference diagram for explaining the operation of the head unit (10) of the delivery stick (30) for wheelchair curling according to the present invention, and FIG. 5 is a cross-sectional view taken along AA of FIG. 2 for explaining the operation of the head unit (10) of the delivery stick (30) for wheelchair curling according to the present invention. With reference to FIGS. 4 and 5, the movement of the connecting column (300) will be explained.

[0061] Referring to FIG. 4, the connecting column (300) of the head unit (10) according to the present embodiment is connected to the holder (200) so as to be rotatable left and right. Specifically, in order to stably apply spin to the curling stone (20) during a user's game, the head unit (10) must naturally come out from the curling stone (20) when the curling stone (20) is thrown. If the connecting column (300) is completely fixed to the holder (200) and does not move, the handle (25) may get caught on the grip surface (231) of the holder (200) when the curling stone (200) rotates during spin throwing, and thus the user may not be able to sufficiently transmit the desired amount of spin to the curling stone (20). In the present embodiment, the connecting column (300) is connected to the holder (200) so as to be rotatable left and right based on the bolt (310), so that when the handle (25) of the curling stone (20) is rotated during spin throwing, the holder (200) also rotates, so that the handle (25) is naturally separated from the grip surface (231) of the holder (200), thereby stably and accurately transmitting the amount of spin desired by the user to the curling stone (20).

[0062] Meanwhile, referring to FIG. 5, the connecting column (300) of the head unit (10) according to the present embodiment is connected to the holder (200) so as to be hinged up and down. Specifically, due to the nature of wheelchair curling, a user seated in a wheelchair holds a delivery stick (30), so that the delivery stick (30) needs to rotate up and down in order to throw a curling stone (20). In the present embodiment, the connecting column (300) is connected to the holder (200) so as to be hinged up and down based on a bolt (310), so that the user can comfortably throw the curling stone (20).

[0063] Meanwhile, a first magnetic body (281) is provided on the upper surface of the holder extension (230), and a second magnetic body (283) corresponding to the first magnetic body (281) is provided on the connection column (300), so that the holder (200) and the connection column (300) can be magnetically coupled.

[0064] Specifically, an inclined surface is formed on the upper surface of the holder extension (230), a mounting groove (237) is formed inside the inclined surface, and a first magnetic body (281) is provided in the mounting groove (237). In addition, a mounting groove (not shown) is formed in a position facing a second magnetic body (283) in a connecting column (300) connected to the holder extension (230), and a second magnetic body (283) corresponding to the first magnetic body (281) is provided in the mounting groove (not shown), so that the holder (200) and the connecting column (300) are magnetically coupled by the magnetic force of the first magnetic body (281) and the second magnetic body (283).

[0065] In the case of the head unit (10) according to the present invention, the connecting column (300) is provided to be rotatable left / right on the holder (200). However, due to this rotating structure, when throwing a curling stone (20), the force applied to the delivery stick (30) by the user is not properly transmitted to the holder (200), and the holder (200) rotates with respect to the connecting column (300), and a phenomenon may occur in which the force applied to the delivery stick (30) is not fully transmitted to the holder (200). In the present embodiment, by magnetically coupling the holder (200) and the connection column (300) through the first magnetic body (281) and the second magnetic body (283) to the holder (200) and the connection column (300), the rotation of the connection column (300) is delayed as much as possible due to the coupling force, so that the force transmitted by the delivery stick (30) can be completely transmitted to the holder (200), thereby enabling the curling stone (20) to be accurately thrown.

[0066] In addition, since the position where the connecting column (300) is magnetically coupled to the holder (200) is specified by the first magnetic body (281) and the second magnetic body (283), the connecting column (300) fixed to the delivery stick (30) and the holder (200) can be aligned in a straight line when the delivery stick (30) is first aimed for throwing the curling stone (20), thereby improving throwing accuracy.

[0067] FIG. 6 is a reference diagram for explaining a process of moving a holder (200) of a head unit (10) of a delivery stick (30) for wheelchair curling according to the present invention, and FIG. 7 is a reference diagram for explaining the amount of spin of a curling stone (20) according to the movement of the holder (200). With reference to FIGS. 6 and 7, a moving structure for moving the holder (200) in the bridge section (130) and the degree of spin applied to the curling stone (20) according to the movement of the holder (200) will be explained.

[0068] Referring to FIG. 6, the bridge portion (130) may further include a slide portion (240) in which a plurality of first gear portions (133) are formed along the first direction, second gear portions (241) corresponding to the first gear portions (133) are formed, and the second gear portions (241) are fastened to the second gear portions (241), thereby fixing the holder body portion (210) to the bridge portion (130).

[0069] Specifically, a plurality of first gear parts (133) are formed on the outer periphery of the bridge part (130) that is inserted into the first through hole (213) of the holder body part (210) along the longitudinal direction of the bridge part (130). At this time, an insertion hole (215) is formed in the holder body part (210) that is in communication with the first through hole (213) and penetrates the inside along the second direction, and a slide part (240) is inserted into the insertion hole (215) so as to be movable in the second direction. The slide part (240) is formed in an approximately rectangular parallelepiped shape, and a second through hole (243) is formed inside so as to be in communication with the first through hole (213) when inserted into the insertion hole (215), and a second gear part (241) corresponding to the first gear part (133) is formed on the inner surface of the slide part (240) formed by the second through hole (243). At this time, an insertion projection (245) that protrudes outward while inserted into the insertion hole (215) is formed at one end of the slide portion (240), and a fixing cap (247) for pressing the slide portion (240) to move the slide portion (240) in the second direction can be coupled to the insertion projection (245).

[0070] At this time, an elastic body (250) for elastically supporting the slide part (240) may be provided between the end of the slide part (240) and the inner wall of the holder body part (210). At this time, a support plate (270) may be provided on the inner side of the holder body part (210), and it is also possible for the elastic body (250) to be provided between the end of the slide part (240) and the support plate (270).

[0071] Below, the process of moving the holder body (210) using the slide part (240) will be described.

[0072] Referring to (a) of Fig. 6, the user first presses the fixed cap (247) to move the slide part (240) in the second direction. By the movement of the slide part (240), the elastic body (250) is pressed and contracted, and the fastening between the first gear part (133) of the bridge part (130) and the second gear part (241) of the slide part (240) is released, so that the holder body part (210) can move in the first direction with respect to the bridge part (130).

[0073] When the first gear part (133) and the second gear part (241) are released from engagement, the user moves the holder body part (210) on the bridge part (130) as much as desired to apply spin to the curling stone (20), and at this time, as the bridge part (130) passes through the first through hole (213) and the second through hole (243), the holder body part (210) moves on the bridge part (130) (see (b) of FIG. 6).

[0074] When the movement of the holder body (210) is completed, the user removes the force applied to the fixed cap (247), and when the force applied to the fixed cap (247) is removed, elastic force is applied by the elastic body (250) arranged between the end of the slide part (240) and the inner wall of the holder body part (210), so that the slide part (240) moves in the second direction again and returns to the initial position, and as the slide part (240) returns to its original state, the first gear part (133) of the bridge part (130) and the second gear part (241) of the slide part (240) engage and are fastened to each other, so that the holder body part (210) is fixed to the bridge part (130).

[0075] By means of this structure, a holder (200) can be provided movably on a base body (100) that is mounted on a curling stone (20) and supports the curling stone (20).

[0076] FIG. 7 is a reference diagram for explaining the amount of spin of a curling stone (20) according to the movement of a holder (200). FIG. 7 (a) illustrates a state in which the holder (200) is moved closer to the connection part (27) of the handle (25) of the curling stone (20). Accordingly, the holder (200) is positioned adjacent to the connection part (27) of the handle (25), so that the amount of spin applied to the curling stone (20) when throwing is not large.

[0077] Figure 7 (b) illustrates a state in which the holder (200) is positioned relatively far away from the connection part (27) of the handle (25) of the curling stone (20). Accordingly, the holder (200) is positioned relatively far away from the connection part (27) of the handle (25), so that the amount of spin applied to the curling stone (20) when throwing is greater than that in Figure 7 (a).

[0078] In this way, the user can control the amount of spin applied to the curling stone (20) when throwing.

[0079]

[0080] In this way, according to the present invention, not only is it possible to stably support a curling stone to enable accurate throwing of the curling stone, but it also has the effect of being able to control the amount of spin transmitted to the curling stone by adjusting the position of the connection part connecting the delivery stick and the head unit.
