Definitions

  • the resistance is found in the lef side from the foot right through to the hand.
  • the left hand which is above the right on the final lever, the shaft, applies resistance to the driving force of the right shoulder, arm and hand as the club enters the final zone of acceleration to impact.
  • the acceleration of the head from the top of the swing to impact is massive, for it must travel from zero to speed in access of 100 mph at the ball, all in about 2/10ths of a second. It is not 'power', as such, that is needed it is pure acceleration which is achieved through the correct application of .leverage in an ordered sequence of motion. Stop action or series photography shows the wrist cock of the top class players retained until very late in th downswing. In the final segment prior to impact the handsmove just a few inches but the clubhead moves many feet, in the same time span. The path traced by the clubhead in the full swing is not a circle in the strict sense but, for our purposes, let us consider it as such for the moment. Peak acceleration can only attain maximum velocity at one tiny segment of that
  • Muscular contraction is not a constant output, it varies according to the task to be performed and the output is allocated by the brain in preprogramming. If a club feel heavy our sub-conscious urge is to lash with it from the ver beginning of the swing down in order to achieve the speed we know we need at the bottom. The wrists release very early and peak velocity is attained much too soon. If, on the other hand, the club feels light headed and very easy to swing then that panic riddent urge to 'lash from the top* * is not there. The lashing effect is at the bottom, where it should be. This also has a marked effect on accuracy for that primal urge is usually accommodated by a lunge of the right shoulder out and around instead of calmly down and under.
  • the objects of the invention are achieved by increasing the weight of the club at or near the grip end of the shaft.
  • the invention in its broadest form comprises an article to be swung in use comprising a handle or shaft adapted to be gripped towards one end by one or both hands and a head or body portion connected towards the other end o the handle or shaft, characterised in that the handle or shaft is given additional weight to move the static balance point of the article as a whole towards the gripped end of the handle or shaft away from the head or body.
  • the weight would be placed as nea to the end of the shaft as possible so that static balance point or the centre of gravity of the club as a whole is moved up the shaft as much as possible.
  • the weight may take any suitable form such as a metal insert in the hollow end o the shaft. This would not effect the appearance or the grip of the club in any way.
  • the shaft 1 has a grip 2 at one end and a metal insert 3 is fitted in the hollow end of the shaft.
  • Th presently used weights for clubheads is more or less the optimum for maximum efficiency.
  • the clubhead weight is rearranged to increase the "mass" effect on the movement of the ball when struck.
  • this is achieved by reducing the size of the hosel 5 and the equivalent weight is added to the club ⁇ head.
  • the weight in the clubhead is rearranged in a special manner. There is an optimum stricking position on the club face of all clubs, commonly called the "sweet spot".
  • the mass behind the sweet spot is so arranged that it is greatly reduced directly behind the sweet spot but is increased around this area. This means that if the ball is struck directly by the sweet spot then the mass all round the sweet spot will contribute to its motion. If, on the other hand the ball is struck slightly off the sweet spot there is still a large mass directly behind it and its motion will not be greatly affected.
  • the useful mass at impact will not be less than that of a conventional club, it will in fac be slightly more although the feel will be much lighter. It will weigh less but the concentration of mass will be centered around the area of impact and not over the entire head and hosel.
  • the clubs to be manufactured in accordance with this invention will approximate the conventional appearance of those already being produced.
  • the aim is to concentrate the most useful mass behind and immediately surrounding the selected impact area on the face of the clubs.
  • the weights finally selected for each individual clubhead throughout the range of golf clubs will be constant in manufacture so that each driver head will weigh the same, each five iron head the same and so forth.
  • the weights of the different heads in the progression from driver through t sandwedge will differ fractionally and progressively, becoming heavier as the loft of the club increases and the shaft length decreases.
  • Another object of the invention is to balance each club against the other throughout the range of the accepted full set of clubs. This is achieved by inserting weight int the hollow top or grip end of the shaft. The greater the weight inserted the closer the point of static balance moves towards the grip end of the club.
  • the formula used is based on the point selected to achieve static balance of the individual club when it is balanced acrosrs an edge so that the shaft lies horizontal.
  • wood clubs will have the constant distance so described from point of static balance to end of grip but this will differ from the length selected for that of the iron clubs. In this manner there will be a selected balance point for all woods within a set of woods and for all irons within a set of irons.
  • the aim of the invention is to maintain such optimum mass for collision but to alter the feel and dynamic weight of the club. The further the point of static balance is moved
  • the golf clubs are to be produced in sets that vary in weight feel as described so that the purchaser has a selection to meet his personal needs. There shall be approximately five standard sets of differing feel and balance. This is very simply achieved by altering the point of static balance from set to set by the use of slightly different series of counter-balance weights in the clubs. The intended purchaser need only test one club from a given set to make his selection and then all other clubs required in the chosen range will be automatically matched to feel, weight and balance to his selected club.
  • a series of counter-balance weights means a given set of weights progressively designed to create the constant distance previously described from point of balance to end of grip. Such a series relates to that set of weights required to so balance a given set of clubs. Five such series will result in five slightly different sets of clubs in terms of feel and balance.

Abstract

L'invention se réfère à des articles qui sont balancés lors de l'utilisation, tels que des articles de sport ou des outils. Dans le cas d'une crosse de golf le centre de gravité de la crosse est déplacé le long de la tige (1) et éloigné de la tête (7) en augmentant le poids à l'extrémité (4) de la tige (1). Ceci est obtenu en utilisant une pièce rapportée lourde (3).
