Description:
A Sports bat

Field of the invention

[0001] Present invention relates to a sports bat and more particularly, relates to the practice sports bat used in ball sports like cricket, baseball etc. for training or practice sessions to help a batter improve his or her batting performance and fielders receive real time catching practice.

Background

[0002] Ball sports game like cricket, baseball etc. have been played since many years. In cricket, to achieve perfection in batting, a batter needs to practice middling the ball. The area of the face of the bat that imparts maximum power to a shot is the middle section of the bat. A ball which is not middled properly by a batsman may result in miscuing or edging the ball. This could lead to the batter's dismissal. In order to enhance the performance of the batter, different practice bats were introduced. For example, to practice middling the ball, batters now a days use a bat with narrow blade. Limitation in practicing with a narrow bat is that a batter either hits the ball or misses it completely. There is no feedback for him whether this ball will be miscued or missed if he plays the same ball with a regular bat, while hitting the bat if it takes the inner edge of the bat, player may get injured.

[0003] US publication US2010/0311525A1 discloses a bat having a handle and a body with a hitting area intended for hitting a ball. The hitting area of the bat is made of a resilient material. The incorporation of a resilient material into a part of the hitting area enables the batsman to use the bat to hit a ball with less effort than using a regular bat. The bat as disclosed in this document though improves the ability of the batsman to provide fielding training, however, does not enables a batsman to practice batting or to enhance the performance of his batting in the field, as the bat in this document does not provides feedback to the batsman about the position where the ball has hit the bat.

Detailed disclosure of the Invention

[0080] The embodiments of the present invention can be understood by reading following detailed description of some of the embodiments with reference to the accompanying drawings. [0081] In an embodiment of the present invention, a sports bat (10) comprises of an elongated handle (20) and a body (40). The elongated handle (20) is connected to the body (40) of the bat (10) along a longitudinal axis. The body (40) of the bat (10) includes a front striking surface (50) and a rear surface (60) opposite to the front striking surface (50). [0082] As shown in Fig. la, lb, lc and Id, the front striking surface (50) comprises of a sweet spot (90) at the lower centre of the bat (10). The sweet spot (90) is a generic term for a person skilled in the art. The sweet spot (90) is defined as the region near the bottom edge of the bat (10) with highest thickness or region most suitable for hitting the ball. The rear surface (60) of the bat (10) comprises of a spine (120) at the centre of the bat (10). The body (40) includes a flexible portion (70) that includes a plurality of flap (72) and a plurality of slit (74), which is structured on the flexible portion (70) at a periphery or edge of the front striking surface (50). The plurality of slit (74) is structured at an angle i.e. may be perpendicular to the longitudinal axis and extends from an edge of the flexible portion (70), thereby partitioning the flexible portion (70) into flaps (72). Fig. 2a and 2b shows a front and back view of the bat, respectively, reflecting spine (120) in the back view of the bat, whereas the sweet spot (90) is shown in the front view of the bat.

[0083] Fig. 3a-3q discloses different arrangement of flaps (72) on the flexible portion (70) of the bat (10). Fig. 3a shows that the alternate flaps (72) have same thickness that can be clearly seen in the side view of the bat (10), whereas as shown in Fig. 3b, the alternate flaps (72) have same width, on both side of the bat (10). Fig. 3c shows another arrangement of flaps (72) in which the length of the slits (74) increases from top to bottom of the bat (10). Fig. 3d shows that the flaps (72) are arranged on left bottom half and right top half of the bat (10). Fig. 3e shows that the flaps (72) are arranged on left bottom and right bottom half of the bat (10). Fig. 3f shows another arrangement of flaps (72) on the flexible portion (70) i.e. with longer flaps (72). Fig. 3g shows that the flaps (72) are arranged on left and right top half of the bat (10). Fig. 3h shows random arrangement of flaps (72) with different slit (74) length like of 15mm, 20mm, 25mm. The flaps (72) as shown in Fig. 3(h) are grouped such that each group has flaps (72) with same dimensions whereas the flaps (72) of adjacent group has different dimensions. Likewise, random combination of flaps (72) can be prepared for the sports bat (10) with each group having same or different combination of flaps with respect to their dimension and also with different combination with respect to adjacent groups. Further, the slits (74) can have different lengths forming either a fixed pattern of length or random lengths of the slits (74). The length of the slit can be of different lengths to form a group, and the adjacent group can also have same pattern of lengths of the slits (74). Fig. 3i shows that the thickness of the flaps (72) increases from top of the bat to the bottom of the bat (10). Fig. 3j shows another arrangement with slit (74) length increasing from bottom to top i.e. the bottom of the bat has shortest slit (74) length, whereas the top of the bat (10) has longest slit (74) length. Figs. 3k and 31 shows another arrangement of flaps (72) i.e. Fig. 3k shows that the flaps (72) are only on the left side of the bat (10) when viewed at the front striking surface (50) and Fig. 31 shows that the flaps (72) are only on the right side of the bat (10) when viewed at the front striking surface (50).

[0084] The body (40) of the bat (10) includes the flexible portion (70) and a rigid portion (80) that comprises of the front striking surface (50) and rear surface (60). The dimension of the flexible portion (70) can be varied with respect to the dimension of the rigid portion (80) i.e. the body may have 50 percent of rigid portion (80) and 50 percent of flexible portion (70), or likewise some other ratios too can be possible. For example, Fig. 3m and 3n shows that only one side of the bat (10) has flexible portion (70) with flaps (72) across its entire length and the other side has rigid portion (80). Fig. 3m shows that the right side of the bat (10) has flexible portion (70) with flaps (72) when viewed from its rear surface (60) and left side has rigid portion (80). Fig. 3n shows that the left side of the bat (10) has flexible portion (70) with flaps (72) when viewed from its rear surface (60) and right side has rigid portion (80). Fig. 3o shows that the flaps (72) are of smaller width near the sweet spot (90) of the bat (10) or slits (74) are closer to each other near the sweet spot (90) of the bat (10), and Fig. 3p shows that the flaps (72) are of larger width near the sweet spot (90) or the slits (74) are away from each other near the sweet spot (90) of the bat (10). Fig. 3q shows that there are no flaps (72) or slits (74) near the sweet spot (90) of the bat (10).

[0085] As shown in Fig. 4a and 4b, the elongated handle (20) is detachably connected to the body (40) by a connecting mechanism (100) structured to vary the length of the handle (20). The connecting mechanism (100) can include plurality of threads on the outer lower surface of the elongated handle (20), as shown in Fig. 4a. The part of the body (40) facing the handle (20) can include a first cavity with inner surface structured to receive the elongated handle (20) by rotation of the elongated handle (20). The more the elongated handle (20) is rotated, the length of the elongated handle (20) decreases and thereby, providing a variable length to the bat (10). The connecting mechanism (100) also enables tilting of the elongated handle (20) i.e. forming an angle with respect to the elongated axis of the bat (10), depending on the number of rotation of the elongated handle (20), thereby providing variable angle to the elongated handle (20). As shown in Fig. 4b, the elongated handle (20) is rotated in opposite direction to increase the length of the elongated handle (10). [0086] Fig. 5 shows the bat (10) with spine (120) on the rear surface (60) of the body (40). The spine can have either a uniform size throughout the rear surface (60) of the body (40) or can have variable size on the rear surface (60) of the body (40). The spine can have variable dimension for fixed dimensions i.e. the spine may extends from the top of the body to the bottom of the body on the rear surface (60), or may extends up to middle portion of the body (40), or may have variable width from top to bottom of the spine (120) on the rear surface (60). For example, Fig. 5 shows that the size of the spine (120) varies on the rear surface (60) of the body with broader size near the bottom of the body (40). [00087] As shown in Fig. 6, the front striking surface (50) of the body (40) of the bat (10) can have either rigid part (52) or flexible part (54) or a combination of both. Fig. 6 shows that the front striking surface (50) has centre rigid part (52) and the remaining flexible part (54). The flexible part (54) can be made of materials like elastomers. The sweet spot can be made of flexible part (54) or rigid part (52).

[0088] As shown in Fig. 7, the body (40) includes a detachable portion (130) which is structured to detachably connect with the body (40) to vary longitudinal length of the bat (10). The detachable portion (130) has a first extension (132) with plurality of threads on its outer surface. The lower portion of the body of the bat can have a cavity to receive the first extension (132) of the detachable portion (130), thereby, providing variable length to the body (40) of the bat (10). Also, the connection between the body (40) and the detachable portion (130) provides a tilt i.e. an angle between the body (40) and the detachable portion (130) being variable in nature. [0089] Fig. 8a-8e shows different arrangement for the placement of spine (120) on the rear surface (60) of the bat (10). As shown in Fig. 8a and 8b, the spine (120) is structured on the right and left side of the rear surface (60) of the bat (10) respectively, with opposite side having flexible portion (70) with flaps (72). Fig. 8c shows that the spine (120) is moved from center towards the left of the rear surface (60) of the bat (10) with respect to the elongated handle (20). Fig. 8d shows that the spine (120) of the bat (10) is in the middle of the rear surface (60) with flexible portion (70) on the right side of the bat (10) when view from front striking surface (50), whereas the other side is not provided with either flexible portion (70) or rigid portion (80). Fig. 8e shows another arrangement wherein the sweet spot (90) is broader than the front striking surface (50) of the bat (10) with flexible portion (70) at only one side of the bat (10).

[0090] Fig. 9a and 9b shows different embodiments for the sweet spot (90). Fig. 9a shows that the sweet spot (90) can include a hole (92), and Fig. 9b shows a broader sweet spot (90) with respect to the remaining part of the front striking surface (50) of the bat (10).

[0091] As shown in Fig. 10, a flexible covering (140) can be provided that can be worn by a normal bat that has a rigid body. The flexible covering (140) has a first opening (142) to receive the body (40) of the bat (10) and circumferentially cover the body (40) of the bat (10). The flexible covering (140) is also provided with one or more second opening (144) that is structured to expose a rigid part (54) or any other part of the front striking surface (50) of the bat (10) such that when an object like a ball hits the flexible covering (140), it deforms for a small interval of time. The flexible covering (140) can be later removed to use the bat (10) for normal matches. The flexible covering (140) can also be provided with flexible portion (70) that further contains plurality of slits (74) partitioning the flexible portion (70) into plurality of flaps (72). The flexible portion (70) covers a periphery of the front striking surface (50). The plurality of slit (74) is structured at an angle from the longitudinal axis and extends from an edge of said flexible portion (70) partitioning the flexible portion (70) into said flap (72), as discussed above. The second opening (144) on the other hand can expose the sweet spot (90) of the bat (10).

[0092] As shown in Fig. l la-l lb, the flexible portion (70) can be detachable connected with the periphery or edges of the front striking surface (50). The flexible portion (70) may include second extension (150), which is received by a third cavity (152) on the periphery of the front striking surface (50) either by sliding into the third cavity (152) or by rotation when provided with threads on the surface of the second extension (150) and on the inner surface of the third cavity (152). [0093] As shown in Figs. 12a-12b and 13, the elongated handle (20) can be detachably connected with the body (40) using connecting mechanism (100) for removal or interchange or exchange of the handle (20) with the body (40), as required by different players. Fig. 12a shows a bat with one type of elongated handle (20), whereas Fig. 12b shows different type of elongated handle (20), which can be detached from the body (40) for interchanging or replacing as per the case. The body (40) of the bat (10) comprises of a second cavity (104) with plurality of ridge on an inner surface of the second cavity (104) as shown in Fig. 13 that receives and holds or stop the movement of the handle (20) after varying the length of the handle (20) to a required limit and after reaching a desired angle of the handle (20) with respect to the longitudinal axis of the bat (10) or with respect to the body (40) of the bat (10).

[0094] Another embodiment of the present invention is shown in Fig. 14 with baseball bat (10). The baseball bat as shown in Fig. 14, comprises of a handle (20) and a body (40) with front striking surface (50) and flexible portion (70) comprising of plurality of slit (74) partitioning the flexible portion (70) into plurality of flaps (72).

[0095] The sports bat (10) of the present invention provides feedback to the batsman with the use of the flexible portion (70) or flexible covering (140) with flexible portion (70) that comprises of flaps (72) that deforms to give feedback that the ball has not hit the sweet spot (90) or desired point on the bat (10) and identifying exactly which part of the bat was hit by the ball. Likewise, the same sports bat (10) can be used for providing catching practice to the players as the bat (10) provides unintentional hit of the ball to the players for the catching practice that enhances their skills. [0096] The present invention is however not limited to the above embodiments disclosed above and referred in Figures 1 to 14 and other embodiments within the scope of the invention can be used for achieving the result of the present invention without limiting the scope of the invention.
