Description
BATS This invention relates to a ball-striking bat and more particularly
relates to a bat, such as a cricket bat, 5 having a handle portion and a ball-striking portion. This invention also relates to a method of manufacturing such a ball-striking bat.
Cricket bats comprise a handle portion, typically formed of 10 one or more pieces of cane in a generally cylindrical configuration and optionally having one or more (typically, one, two or three) vibration- absorbing components extending axially of the handle, for example extending diametrically of the handle in a plane substantially parallel to a 15 hitting face of the bat, and a ball-striking portion, or blade, typically formed of a single piece of wood, especially willow.
The handle portion, where it engages with the ball-striking 20 portion, is generally of triangular cross-section in the axial direction so as to engage in a corresponding recess of triangular cross-section formed at one end of the ball striking portion.
25 The ball-striking portion has a generally rectangular ball striking surface and has a thickness which increases
progressively from the handle portion to a maximum and which subsequently decreases. The maximum thickness of the ball-striking portion is generally about two-thirds of the length of the ball-striking portion from the handle end of 5 that portion.
The thickness of the ball-striking portion also increases progressively from the longitudinal edges of that portion towards a line extending in the axial direction along the 10 centre of the ball-striking portion.
The handle portion and the ball-striking portion are secured together with a suitable adhesive.
15 Since cricket bats are made of natural materials, the ball striking properties and "feel" of cricket bats and other ball-striking bats made of similar materials varies unpredictably from bat to bat. It would be advantageous to be able to manufacture a bat which has more predictably 20 uniform properties. It would also be desirable to be able to manufacture a bat which has improved properties over those possessed by the natural materials used.
It is therefore an object of the present invention to 25 provide a ballstriking bat which possesses one or more of the abovementioned features.
According to one aspect of the present invention there is provided a ballstriking bat comprising a handle portion of a first material, a ballstriking portion of a second material secured at one end region thereof to an end region 5 of the handle portion, and a rod member of a resilient third material extending through the handle portion and into the ballstriking portion.
According to another aspect of the present invention there 10 is provided a method of manufacturing a ball-striking bat comprising the steps of providing a handle portion of a first material; providing a ball-striking portion of a second material; securing one end region of the ball striking portion to an end region of the handle portion; 15 and inserting a rod member of a resilient material through the handle portion and into the ball-striking portion.
The handle portion may be substantially cylindrical.
20 The handle portion may be made of a natural material, such as cane.
The ball-striking portion may have a substantially rectangular ballstriking surface.
The ball-striking portion may have a thickness which increases progressively from an end thereof adjacent to the handle portion to a maximum and subsequently decreases.
The maximum thickness of the ball-striking portion may be 5 from one-half to three quarters, preferably substantially two-thirds, along the length of the ball-striking portion from the end thereof adjacent to the handle portion.
The ball-striking portion may have a thickness which 10 increases progressively from longitudinal edges thereof towards a centre line of the ball-striking portion.
The ball-striking portion may be made of a natural material, such as willow.
A single rod member of resilient material may extend through the handle portion and into the ball-striking portion. 20 The rod member may have a diameter of 10 to 15 mm.
The rod member may have a length such that it extends from one-half to three quarters, preferably about two-thirds, of the length of the ballstriking portion. Alternatively, 25 the rod member may extend to substantially the region of maximum thickness of the ball-striking portion.
The rod member may be of substantially constant diameter.
Alternatively, the rod member may taper such that the diameter thereof decreases with increasing distance from the free end of the handle portion.
The rod member may be a close fit within a bore formed through the handle portion and into the ball-striking portion. 10 The resilient material may comprise a reinforcing fibre material embedded in a resin matrix. The reinforcing fibre may be selected from carbon fibre, boron fibre, glass fibre and aramid fibre, and mixtures thereof. The resin matrix may comprise an epoxy resin. Alternatively, the rod member 15 may comprise a metal.
The rod member may be in the form of a solid substantially cylindrical member.
20 Alternatively, the rod member may be in the form of a hollow substantially cylindrical member. In such a case, the rod member may be provided therein with a shock- and/or vibration-absorbing material. The shock- and/or vibration absorbing material may be selected from a resilient 25 material such as an elastomer (for example, rubber), a foamed plastics material and cork, and mixtures thereof.
- 6 The rod member may be provided with a sheath of shock and/or vibration-absorbing material. The shock- and/or vibration-absorbing material may be selected from a resilient material such as an elastomer (for example, 5 rubber), a foamed plastics material and cork, and mixtures thereof. One or more diametral slits may be formed in the handle portion and the rod member and one or more sheets of shock 10 and/or vibration-absorbing material may be secured in such one or more slits. The one or more slits may be in a plane substantially parallel to a ballstriking surface of the ball-striking portion. The shock- and/or vibration absorbing material may be selected from a resilient 15 material such as an elastomer (for example, rubber), a foamed plastics material and cork, and mixtures thereof.
For a better understanding of the present invention and to show more clearly how it may be carried into effect 20 reference will now be made, by way of example, to the accompanying drawings in which: Figure 1 is a front view of one embodiment of a cricket bat according to the present invention)
- 7 - Figure 2 is a side view of the cricket bat shown in Figure 1; Figure 3 is a top view of the cricket bat shown in Figures 5 1 and 2; Figure 4 is a side view of one embodiment of a rod member for insertion into a handle portion and a ball-striking portion of the cricket bat shown in Figures 1 to 3; Figure 5 is a top view of the rod member shown in Figure 4; Figure 6 is a side view of another embodiment of a rod member for insertion into a handle portion and a ball 15 striking portion of the cricket bat shown in Figures 1 to 3; and Figure 7 is a top view of the rod member shown in Figure 6.
20 The cricket bat shown in Figures 1 to 3 comprises a handle portion 1 and a ball-striking portion 3, the handle portion and the ball-striking portion being secured together by means of a suitable adhesive (not shown) .
25 The handle portion 1 is made of cane and is generally cylindrical in configuration and provided with a V-shaped
8 - protrusion 5 (as seen in Figure 1) which extends into a complementary recess formed in the ball-striking portion 3.
In use, the handle portion may be bound with a cord and is covered with a flexible hand grip (not shown), for example 5 of rubber, in known manner.
The ball-striking portion 3 is made of willow and has a generally rectangular ball hitting face 7 as shown in Figure 1. As best shown in Figure 2, the thickness of the 10 ball-striking portion increases progressively from the lower end of the handle portion 1 to a region 9 of maximum thickness before decreasing again towards the lower edge of the ball-striking portion. The region 9 of maximum thickness is about onehalf to three-quarters, for example 15 about two-thirds, along the ballstriking portion from the handle end thereof.
As best seen in Figure 3, the thickness of the ball striking portion 3 also increases progressively from 20 longitudinal edges 11 of the ballstriking portion towards a line (not shown) extending along the centre of the ball striking portion.
As can be seen from Figures 1 to 3, a single rod member 13 25 extends through the handle portion 1 and into the ball
- 9 striking portion 3. The rod member 13 is shown in more detail in Figures 4 and 5.
As can be seen from Figure 5, the rod member 13 comprises 5 a core 15 and a sheath 17.
The core 15 is in the form of a solid, flexible, resilient cylindrical rod of reinforcing fibre material embedded in a resin matrix. The reinforcing fibre may be, for example, 10 selected from carbon fibre, boron fibre, glass fibre, aramid fibre (such as that sold under the trade mark KEVLAR) or other suitable reinforcing fibre. The resin matrix may be, for example, an epoxy resin material.
Alternatively, the core 15 may be made of a rod of metal, 15 such as aluminium or steel (for example spring steel).
The sheath 17 is optional and, where provided, comprises a shock- and/or vibration-absorbing material such as a flexible or resilient material, for example rubber, cork or 20 a foamed plastics material.
The rod member 13 may have any suitable diameter, for example in the range from 10 to 15 mm. The rod member may have a length such that it extends substantially from the 25 free end of the handle to about the region 9 of the ball striking portion 3 of maximum thickness. Alternatively,
- 10 the length of the rod member 13 may be such that it extends to about half to about three-quarters, generally about two thirds, of the length of the ball-striking portion.
5 The rod member 13 is inserted into the cricket bat by drilling a bore through the handle portion 1 and into the ball-striking portion 3 of the bat, the length of the bore corresponding substantially to the length of the rod member 13 and the diameter of the bore being such that the rod 10 member 13 is a close fit within the bore. The bore extends substantially along the axis of the handle portion 1 and continues in a straight line into the ball-striking portion 3. 15 In addition to the sheath 17, or as an optional alternative thereto, once the rod member 13 has been secured in the bore one or more diametral slits (not shown) may be formed in the handle portion (and the rod member) in a plane substantially parallel to the face of the bat and one or 20 more sheets of shock- and/or vibration-absorbing material, such as rubber or cork, may be secured in such one or more slits in known manner.
Although the rod member 13 is shown as being of uniform 25 diameter, if desired the rod member may be tapered such that the diameter of the rod decreases with increasing
- 11 insertion depth. In such a case, advantageously the diameter of the bore also decreases in corresponding manner to maintain a close fit between the internal surface of the bore and the external surface of the rod member.
If desired, as shown in Figures 6 and 7, the rod member 13 may comprises a sheath 19 and a core 21.
In such a case, the sheath 19 is in the form of a hollow, 10 flexible, resilient cylindrical member of reinforcing fibre material embedded in a resin matrix. The reinforcing fibre may be, for example, selected from carbon fibre, boron fibre, glass fibre, aramid fibre (such as that sold under the trade mark KEVLAR) or other suitable reinforcing fibre.
15 The resin matrix may be, for example, an epoxy resin material. Alternatively, the sheath 19 may be made of a hollow cylinder of metal, such as aluminium or steel (for example spring steel).
20 The core 21 is optional and, where provided, comprises a shock- and/or vibration-absorbing material such as a flexible or resilient material, for example rubber, cork or a foamed plastics material.
- 12 As a further option, a sheath (not shown) of shock- and/or vibrationabsorbing material similar to the sheath 17 may be provided.
5 In addition to the core 21 and/or a sheath corresponding to sheath 17, or as an optional alternative to either or both, once the rod member 13 has been secured in the bore one or more diametral slits (not shown) may be formed in the handle portion (and the rod member) in a plane 10 substantially parallel to the face of the bat and one or more sheets of shock- and/or vibration-absorbing material, such as rubber or cork, may be secured in such one or more slits in known manner.
15 Further, if desired, the rod member of Figures 6 and 7 may be tapered as discussed above in respect of Figures 4 and 5. It has been found that the rod member 13 allows the bat to 20 flex in a manner expected by the user, but by appropriate selection of the materials and properties of the rod member (employing a number of straightforward experiments not involving any invention) the "feel" of the bat can be made more uniform and the hitting properties of the bat can be 25 improved due to the resilient nature of the rod member.
That is, the blade of the bat can be made to spring back to
- 13 its original configuration as the ball is hit in such a manner as to project the ball more effectively in the desired direction.
