## Title
Table-tennis bat(pen-holding type)

## Abstract

The inventions published consist of ‘split-level step’ between bat handle and contact section. This said step provides the newly inventions here the concept of critical holding points (called as C.H.P.)for the thumb, forefinger and any of other three fingers. These fingers can grip firmly onto the said step. This allows better swing of the bat, angle control, flexibility of bat manipulation and power. These C.H.P. also provides the proper gripping areas so that finger deformation problem is less likely to happen.
In addition, it is less strainuous physically for the wrist and fingers, so the better power and performance of the players can be maintained longer naturally throughout the games.
Besides, the invented C.H.P.concept can also be achieved (although it is less ideal compared to the ‘split level Step’) without adopting the ‘split-level step’(that is with the bend/joint angle between the split level equals zero degree) by having ‘raised-height-block’ or raised step or ‘prolonged bottom handle’ front and/or at the back of the bat (see Y & Z in FIGS. 3,4,5,6 & 7) so as to act as the C.H.P. as found in the split-leveled step (see X in FIGS. 2,4 & 7) (Note: to use drawing 7 for article publication purpose).

## Background
TECHNICAL FIELD
The present innovation relates to pen-holding type of table-tennis bat.
BACKGROUND ART
The existing pen-holding-table tennis bats are made as shown in FIG. 1. (the literature here below all refers to pen-holding table tennis bats) These bats are not ergonomics enough for firm holding and flexibility for good exertion of wrist and finger strengths for better power and performance of the players.
This is due to insufficient firm and critical holding points on the bat for the exertion of wrist and finger power. This reduces the power of the play and also at times causes more possible deformation of the finger (eg: the middle finger is ‘bent’ and deformed slightly) due to exertion of finger strength onto the bat without proper holding points on the bat.
The new invention shown here consists of a ‘split-level step’ between bat handle and contact section (bat contact section here refers to the section of the bat where the rubber is adhered to). This means that either one of the plane of the handle and the contact section is higher than the other (see FIG. 2). This is improved from existing old design where both sections are made in the same plane. This said step (see ‘x’ in FIG. 2) provides the new invention and concept of ‘critical holding points’ (so called ‘C.H.P.’ in the following literature) for thumb, forefinger and any of other three fingers. These fingers can grip firmly onto the said step. This allows better swing of the bat, angle control, flexibility of bat manipulation and power. These C.H.P also provides the proper gripping areas for finger rest so that finger deformation problem is less likely to happen.
In addition, due to this invention of the good C.H.P., it is less strainuous physically for the wrist and fingers, so better power and performance of the players can be maintained longer naturally through out the game.
In addition to the published new invention of ‘split-level step’, the C.H.P. concept can be achieved (although it is less ideal compared to the ‘split level step’ design) without adopting the ‘split-level step’ by having ‘raised height’-block or step or ‘prolonged bottom handle’ design in front and/or at the back of the bat (See Y&X in FIGS. 3,4,5,6&7) acting as the C.H.P. as found in the ‘split-level step’. (see X in FIGS. 2,4&7). These ‘raisedheight’ blocks or steps and ‘prolonged bottom handle’ are also claimed and published here as the new design or invention here. (see under ‘Claims’)

Summary of 8 different embodiment of the C.H.P adopting the split level step (X), prolonged bottom handle and raised height blocks are as below:
(1) The bat comprises of a flat planar section (‘U’) with a handle (‘V’) integrally joined to the said flat planar section wherein two different planes with a split-level step (‘X’ in FIG. 7) in such a manner that a prolonged bottom handle piece (‘Z’) with tapered and thicker curved portion (or of any shapes or forms) at one end, stretching from the handle section towards the flat planar section forming the raised bottom step (X), is used to act as holding points for all or any of the middle, fourth and little fingers can press firmly against the the thumb and forefinger from bottom and top (at ‘X’) respectively towards the centerline of the said flat planar and/or handle and/or joint section.
(2) The bat comprises of a flat planar section (‘U’) with a handle (‘V’) integrally joined to the said flat planar section wherein two different planes with a split-level step (‘X’ in FIG. 2) in such a manner that single or multiple ‘raised-height-blocks’ (‘Y’) of any forms or shapes at the bottom side of the flat planar section forming the raised bottom step (X) are used to act as 1 holding points where all or any of the middle, fourth and little fingers can press firmly against the the thumb and forefinger from bottom and top (at ‘Y’) respectively towards the centerline of the said flat planar and/or handle and/or joint section.
(3) The bat comprises of a flat planar section (‘U’) with a handle (V’) integrally joined to the said flat planar section wherein two different planes with a split-level step (‘X’ in FIG. 2) forming the raised bottom step (X) in such a manner that the joining portion between the handle and flat planar section forms an integral or joined part of the handle portion in a 45 degree or any other inclination angle slope or step of any forms in which the slope itself provides the unique critical holding points where all or any of the middle, fourth and little fingers can press firmly against the the thumb and forefinger bottom and top (at ‘X’) respectively towards the centerline of the said flat planar and/or handle and/or joint.
(4) The bat comprises of a flat planar section (‘U’) with a handle (‘V’) integrally joined to the said flat planar section wherein two different planes with a split-level step (‘X’ in FIG. 4) forming the raised bottom step (X) in such a manner that a prolonged bottom handle piece (‘Z’) without any tapered and thicker curved portion (or of any shapes or forms) stretching from the handle section towards the flat planar section, can be used to act as holding points where all or any of the middle, fourth and little fingers can press firmly against the the thumb and forefinger bottom and top (at ‘Z’) respectively towards the centerline of the said flat planar and/or handle and/or joint.
(5) A bat comprises of a flat planar section (‘U’) with a handle (‘V’) integrally joined to the said flat planar section in the same plane (where the split-level step joint/bend angle is zero degree) in such a manner that a prolonged bottom handle piece (‘Z’ in FIG. 6) with tapered and thicker curved portion (or of any shapes or forms) at one end, forming the raised bottom step (X), stretching from the handle section towards the flat planar section is used to act as critical holding points where all or any of the middle, fourth and little fingers can press firmly against the the thumb and forefinger from bottom and top (at ‘Z’) respectively towards the centerline of the said flat planar and/or handle and/or joint.
