Definitions

  • the present invention relates to an improvement in cricket bat and more specifically to improvement in cricket bat wherein the cricket bat is a single piece and is made up of metal or alloy.
  • a cricket bat comprises a generally rectangular elongate blade part of solid wood, usually willow, and a handle of cane secured to the blade by means of a tapering splice joint.
  • the cane handle incorporates a layer or layers of a rubber or cork material forming a laminated assembly which is intended to suppress vibration when the ball is struck. The vibration suppression avoids undue discomfort to the batsman's hands during play.
  • cricket bats The general shape of cricket bats has remained standard for many years. The shape of cricket bats has been standard and little changed for the best part of 150 years.
  • the handle of a cricket bat It is desirable for the handle of a cricket bat to be light in order that as much as possible of the batsman's effort in swinging the bat is transferred to the ball.
  • the handle must also have sufficient structural stiffness to transmit the maximum amount of energy from the batsman's hands to the blade of the bat and thus to the ball.
  • willow alternatives such as synthetic materials
  • the resulting bats have generally failed to replicate the desirable playing characteristics of willow, and have also not met the regulations of the professional game, which require a wooden striking surface of the blade and tightly control the use of other materials in the bat that may increase its power by altering, amongst other things, its elasticity.
  • the blade of a cricket bat is conventionally finished with paint, using a brush technique directly onto the willow, this generally being done merely to hide blemishes or imperfections in the wood.
  • this finishing technique is not ideal as the paint typically cracks or fades rapidly in use.
  • cricket bats have been made of willow and the handle is spliced into the blade.
  • the rear surface of the bat has traditionally been shaped to be convex in cross section and/or V shaped which in turn however, requires knocking in before use for hardening and conditioning of the blades' surface and the conventional bat does not last for long and is rendered useless after about a year of its normal use:
  • the object of the present invention is to provide a cricket bat maintaining the favorable playing characteristics of conventional willow bats, and also meets all cricket bat regulations but has Improved strength as compared with existing constructions, is cost effective and eco friendly. Furthermore, the object of the present invention is to devise a bat which has longer life. The present invention satisfies the above said needs.
  • the said invention relates to an improved bat made of a metal or its alloy wherein holes have been provided on the back side of the blade of the bat. Since professional cricketers require heaviness in the bat at a particular area which may be the bottom, center or the upper portion of the bat, thus to overcome the said problem weights can be inserted in the said holes such as lead balls to make the bat heavy at the desired area.
  • the present invention relates to a further improvement in cricket bat wherein the blade and the handle of the cricket bat is made of a metal or its alloy, wherein the said handle and blade are in single piece, keeping in view that the weight of the bat is not increased.
  • the most suitable material being aluminum, titanium, magnesium etc. which are cost effective and eco friendly i.e. there is no need to cut the trees for making the bat as the conventional bats are invariably made of wood.
  • the bat has been designed as a monolithic mass in which the blade and handle is a one piece construction wherein the strength to withstand forces is greatly increased.
  • the inner tube/pipe or the handle of the bat runs from the top to the bottom of the bat thereby giving more strength to the bat.
  • the inside portion of the blade has a sinusoidal waveforms which quickly distribute the kinetic energy when the ball hits the bat.
  • the present invention describes an improvement in cricket bat wherein the blade and the handle of the cricket bat is made of a metal or its alloy keeping in view that the weight of the bat is not increased.
  • the most suitable material being aluminum, titanium, magnesium etc. which are cost effective and eco friendly i.e. there is no need to cut the trees for making the bat.
  • the bat has been designed as a monolithic mass. As the blade and handle is a one piece construction hence the strength to withstand forces is greatly increased.
  • the inside portion of the front hitting portion of the bat has a sinusoidal waveform (Item 6 in Figure 3). This makes dissipation of energy faster.
  • the impact forces received as a result of the kinetic energy being transferred from the ball to the bat gets quickly distributed with this kind of a construction and the sinusoidal waveform.
  • Other waveforms will also work with similar results and this concept is not limited to this kind of a waveform.
  • the top surface of the bat is coated with composite 5 polymer such as epoxy resin, polyurethane, natural synthetic rubber etc. to increase the control of the ball by the user and also to reduce the vibration which would have resulted otherwise from the impact of the ball on the bat.
  • composite 5 polymer such as epoxy resin, polyurethane, natural synthetic rubber etc.
  • the inner hollow portion of the bat is filled with composite light weight material to absorb vibration created on the bat being hit by the ball.
  • the strength of the bat would be increased when the density of the filler is increased.
  • the front part of the bat is thicker than the rear part with twice the thickness so as to make the bat be within the weight range of 0.8 kg to 1.40 kg. This weight range being the most ideal for a batsman.
  • a tube/pipe has been inserted through the handle of the bat that runs through the bat from top to the bottom and act as a spinal cord of the bat and provides strength to the entire structure.
  • bobs which runs from the top to the bottom (Item 1 in figure 2). These bobs are an intrinsic part of the monolithic structure. Because of the way they are piaced they increase the strength of the handle. This added strength prevents the handle from breaking away from the blade. Bobs will not be required in the bats where the strength required is lesser.
  • the bat with the tube/pipe is curved to provide the convex structure that is needed for good quality stroke.
  • Springs or sleeves may be added to get back the handle to its original position with respect to the blade after impact with the ball.
  • the hollow portion in the bat is filled with vibration absorbing compounds. When filled with such compounds the vibration felt by the batsman is greatly reduced.
  • the bats can also be made without filling absorbing compounds to reduce the weight of the bat which can be used to play with tennis balls.
  • the bats with the lighter weight range are for the purpose of use by the persons who would like to play the Cricket with soft balls such as tennis ball. Another use can be for the use for training purposes, where the lighter bats are required for correcting the strokes and muscular memory. retention of players. Such usage can be widely used in gully cricket like in Indian subcontinent and at beaches in rest of the world
  • a sleeve may be inserted to provide additional strength as the area between the blade and the handle is the weak link of the entire structure.
  • the sleeve may be put in by one of the many fitment techniques such as push fitting, heat shrink fitting, riveting etc.
  • the sleeve may be made of any high strength alloy or steel, aluminum or any other alloy which will give the desired strength.
  • Conventional bats have toe at the rear bottom portion of the bat.
  • the present device does not have the same and functions better as there is uniform material in the complete structure providing stability during the impact " of the ball.
  • Conventional bats have a hump at the rear portion directly behind sweet spot of the bat whereas the present device does not have this so as to maintain uniform weight stability and maintaining the centre of gravity of the structure at a more comfortable point for the batsman while retaining the same utility.
  • the bottom of the bat i.e. toe is provided with the grooves to increase the friction with the ground.
  • the present invention provides an efficient and cost-effective way for an improved cricket bat
  • the bat as per the present invention lasts longer and has about 10 times life as compared to the conventional bat.
  • Figure 1 is the front view of the bat with the cap wherein the blade and the handle is a single piece construction.
  • Item 8 in the figure 1 is the cap.
  • Figure 3 is the sectional profile view of the blade. Item 7 in said figure are the bobs. Item 3 in figure 5 is the composite light weight material to absorb vibration and increase strength of the bat.
