Description

GOLF BALL FOR SOFT BLOWS BACKGROUND OF THE INVENTION This invention relates to a golf club for soft strokes, more specifically to a golf club for soft strokes, especially with counterweight, in such a way that it keeps the wrists in an immobilized state (potential immobilization of wrist) and maintain some control of the head when starting and completing a soft stroke. Approximately 40-60% of all golf games take place on the turf and involve the use of a golf club for soft strokes. Consequently, the practice of rolling play is a critical part of the game. The mastery of the technique of rolling practice projects a golf player towards a higher quality of play. The best soft stroke is one in which the stroke is smooth, fluid, uninterrupted, free of jerks and loose and is in line with the proposed targets; the ball and the hole. The soft-hitting golf clubs basically consist of a handle, a golf club head for a gentle blow on one end of the handle (bushing), and a stop having a handle on the other end of the handle; the stop being farthest from the club head for soft hits. There are three basic styles of rowing practice; (1) the pendulum hit, (2) the wrist-lifted hit, and (3) the wrist hit. The first two are the most common and are used in the same way by the vast majority of golf players; amateurs and professionals. Each of the two common styles uses the shoulders as the focal point and forces the blow backwards. The arms, wrists and hands meet and remain immobilized during the entire blow. The ball is "pushed" instead of hit. The blow should be smooth, fluid, and uninterrupted, free of jerks (blow cut) and loose (small interruptions to the blow). In a vertical plane the head of the club for soft hits should not pass beyond the hands of the golfer. In particular, the wrists must remain in immobilized position since any movement in the wrists increases the reaction in the head of the club for soft blows. The only difference between these two styles is in the hand-wrist positions and the alignment of the handle with respect to the shoulders. In the pendulum style, the arms from the shoulders descending form a "V"; the wrists are in line with the arms. The handle of the golf club for soft blows cuts substantially the "V" and is in substantial alignment in a straight line from the club head for soft hits to the shoulders. Through this alignment, the handle becomes a long lever artificially extended from the top of the handle to the focal point of the stroke. The shoulders as the fulcrum push the blow through the ball. In the doll-up style, the arms and elbows are straight, but the wrists and hands are immobilized in a slightly raised position. The handle of the golf club for soft blows with this bends slightly at an angle in relation to the cut point of the "V" described above. In this style, the shoulder also acts as the focal point and point of support to push the shot through the ball. The dolls must remain immobilized in their raised position. As with the pendulum style, the arms, in the immobilized form, move one after the other with the shoulders. The hands try to hold the golf club for fixed soft strokes during the stroke. In all styles, a heavier head (in relation to the total weight of the club for soft hits) causes the head to accelerate prior to impact with the ball. This is commonly referred to as "dropping the head" or, as used herein, "head control". The last style is the least used; mainly by the beginners. In this style, dolls instead of shoulders provide the driving force for swinging instead of hitting the golf club for soft strokes. The dolls are released and become the turning point of the balance. The ball is hit instead of touching and, on a vertical plane, the head of the club for soft blows swings beyond the hands. In all styles, a club head for heavier strokes in relation to the total weight of the club for soft hits causes the head to self-accelerate prior to impact, thereby decreasing the golfer's control over the soft hit given to the ball. , this is commonly referred to as "freeing the head", or as used in the present, "head control". From the bottom of the clubhead to soft hits to the top of the handle, golf clubs for soft hits generally range from 30 to 40 inches in total length. Of this total length, the handle comprises between 30 to 34 inches and can be inserted directly into the head of the club for soft hits or by means of a hosel (cavity of the head of the cane that receives the handle). Golf clubs for conventional soft strokes generally weigh between 450 and 520 grams. Of this weight, the head of the stick for soft blows comprises between 300 and 340 grams, the handle between 85 and 95 grams, the grip between 60 and 70 grams, and the material varied between 5 and 15 grams. As can be clearly seen, the clubhead for soft hits covers approximately two-thirds of the total weight of the club for soft hits. The distribution of the relative weight between the golf clubs for soft strokes is approximately the same. A typical conventional soft stroke golf club is about 35 inches long. It has a 32-inch handle, and weighs approximately 485 grams. Of that weight, the head of the golf club for soft strokes comprises approximately 320 grams, the handle approximately 90 grams, the handle approximately 65 grams, and the material varied approximately 10 grams. The point of balance of this typical club for conventional soft strokes (that is, the point on the golf club for soft strokes in which it swings perfectly) is approximately 9 flushes from the head of the golf club for gentle strokes and 26 inches from the top (or approximately 74.3% of the length from the top). Balance weight is still another important variable associated with golf clubs (mainly wood and iron) and is used to properly adapt a club for its intended use. The weight of the balance is determined by measuring the distribution of the total weight of the club approximately at a point of support established at a specific distance (either 12 or 14 inches depending on the type of scale used and the interpretation of the measurement) from the top of the club and the point of balance of the club. A 14-inch support point scale (referred to as a Lorithmic or Prorhythmic scale) is typically used by mast manufacturers while a 12-inch support point scale (referred to as an official scale) is typically used by workshops repair. Prorhythmic scales measure balance weight by assigning alpha-numeric characters to weight; that is, from A to H as the primary characters with the numerical increments of 10 between each increment of successive alpha-character (for example, A-0, Al, A-2 ... A-9, B-0, and so on). A measure of A-0 is a lightweight balance weight equal to a balance weight of 650 grams. A measure of H-0 is the highest on the Prorhythmic scale and equal to a balance weight of 1120 grams. The balance weight of a typical conventional soft-stroke club (ie, total weight of 485 grams, total length of 35 inches, which has a rolling point of 26 inches from the top), is D-0; or a balance weight of 850 grams. The farther away the head of the golf club is from the focal point of the stroke, the more difficult it is to execute a successful soft stroke. Conversely, the closer you are to the focal point of the stroke, the less difficult it is to execute a successful soft stroke. In the club for conventional soft strokes, with the focal point (shoulders) of the lever at such a distance from where the volume and weight of the club for soft strokes are concentrated (club head for soft strokes) , the golfer faces a difficult task when trying to hold firmly the golf club for soft hits and keep the wrists decidedly immobilized during the critical moments of the practice of rolled play. The reason for this difficulty is that the hands hold the golf club for soft strokes at a distance of between 32 and 35 inches from the bottom of the golf club head for soft strokes and, depending on the length of the golfer's arm , between 20 and 28 inches from the focal point (shoulders) of the blow. The golf club for soft strokes, despite being relatively light, has a heavy weight balance, which, due to this weight, encourages instead of inhibiting unwanted movement. Therefore, getting and maintaining the immobilized wrist potential and a free stroke of movement in this distribution-weight environment is extremely difficult. With the concentration of the weight at such a low point and so far from the hands, and even further from the focal point of the blow, once the blow is initiated and the head is released, it is difficult to control the head and has a tendency to self -acceleration and take control of the blow. In attempts to prevent bending, bowing, shaking, jerking, releasing, and nullification and potential weakening of the immobilized wrist, the hands are forced to counteract the forces of the golf club head for gentle strokes once that this is set in motion. Such attempts also often result in either a hesitation or a withdrawal from the blow while still trying to achieve and maintain the wrist immobilization potential. More often, the hands wobble, the wrist immobilization potential is not achieved, or, if it is achieved, it is locked, the handle moves, and the blow becomes cut and less fluid. Even if the clubhead for soft hits remains aligned with the ball, the smaller change in the handle position causes the ball, whether it is pushed (pass slightly forward of the golfer and away from the hole) or pull (pass slightly behind the golfer and move away from the hole). Other factors, such as tension, anxiety, nerves, and increased levels of adrenaline, also aggravate the problems generally associated with the practice of rolling play. Any of those, united with the physical movements involved in the attempt to execute a perfect soft blow, could adversely affect the stroke and the final result of the soft stroke. Attempts to correct this problem have included the filling of the handle, from the upper cap, with sand of superior quality, and other particles. These attempts have failed to solve the problems addressed above. In such cases, the real source of the problem is that the golf clubs for soft strokes have become heavier than normal without the corresponding decrease in the weight of the clubhead for a soft hit. In some cases, the golf club for soft hits becomes noisy while it is used, depending on the weight changes. All these attempts have adversely affected the balance, speed, and feel of the blow and have failed to achieve the desired wrist immobilization potential or to correct the shaking, release, hesitation, and similar smaller movements of the hands and wrists. Because the touch of the golf club has been altered for soft strokes and stroke, the golfer experiences an uncontrollable need to prevent the blow before it starts. All these attempts have only worsened the final result of the soft stroke. Other improvements to golf clubs in general have involved the addition of weight to the handle while reducing head weight (Mather, and Cois, 5,152,527); - lu ¬ the addition of weight to the golf club handles without any change in the weight of the club head (Benzel, 5,244,209, Mitchell, 4,461,479, and Karns, 3,075,768); the adjustable addition of the weight to the outside of the golf club handles (Tanampai, 5,178,394, and Burnett, 3,680,870). While Mather ('527), Benzel (' 209), Mitchel ('479), and Karns (' 768) refer to golf clubs in general, they treat the power variations associated with the total swing sticks. Weight is added in relation to the force needed to complete a total roll and push the ball further when hit. Each one directs the full range of golf clubs in which their respective concept could be used. Each, however, excludes the club for soft hits since the concepts associated with the full swinging clubs are inappropriate for the fluid stroke associated integrally with a soft stroke. Mather ('527) demands a corresponding decrease in the weight of the club head as an absolute requirement for the complete optimization of the variation of power at the point of non-lifting of the wrists during a total roll in a ball. For golf clubs that vary in weight from 350 to approximately 500 grams, after reducing the weight of the clubhead from 40 to 50 grams, respectively, Mather teaches adding between 80 to 160 grams respectively, for a total weight increase of golf club from 40 to 110 grams or from 11.4% to 22%, respectively. The weight of the club head is reduced from 13% to 30%. These ranges teach that the power of balancing will be optimized in the phase where the dolls begin not to rise. None of the teachings addressed above fit the purpose, scope, function and structure of a golf club for a soft stroke. In addition to the physical aspects of golf, the game involves numerous psychological aspects. Emotional and visual distractions often affect the quality of the game. The use of additional weights on a club for soft hits, as described by Tanampai ('394) and Burnett (' 870), are a visual distraction to the most critical facet of the game. Also, these can cause damage to the handle. The appropriate balance needed to achieve the wrist immobility potential can not be established by the use of additional weight. Such weights are not uniform and adversely affect the concentration of the golfer. The additional weight, without a corresponding decrease in the weight of the clubhead for soft hits, will alter the tact, the traditional speed, and the suit of the golf club for soft hits. With these alterations, the execution of the blow is unfavorably altered. These additional weights do not diminish or prevent the shake, release, and hesitancy associated with the practice of rolling play and such problems have not been solved during this critical phase of the game. This does not encourage the achievement of the immobility potential of the doll which is critical for a successful soft stroke. The concentration of such weights on the outside of a handle without the decrease in the weight of the club head for soft blows leads to poor soft blows; greater (instead of less) control of the head; and generally a somewhat uncontrollable acceleration of the blow. To achieve the proper point of balance using these addition devices without affecting the touch and play of the club for soft strokes requires that the additional weight be placed on the handle in a location where the hands hold the club for strokes soft. This, of course, interferes with the ability of the hands to grab and hold the golf club thus avoiding the purpose for which the weight was proposed; that is, you can not use the golf club for soft strokes. In addition, these devices were designed primarily for full swinging poles (wood and iron) to accommodate and improve a full swing power swing at the point of a roll where the wrists do not rise and provide additional strength to the swing to propel the ball farther when hit. These devices were not designed for, nor can they be adapted for proper use on a golf club for soft strokes in such a way as to maintain the fluidity of the stroke. The previous mention of the co-pending application (Serial Number 08 / 415,137 filed on March 31, 1995) solves the problems associated with the practice of rolling play when creating a golf club for soft strokes with predetermined additional weight of a length predetermined at a predetermined location along the handle of a golf club for smooth strokes and by providing a club head for soft strokes having a predetermined weight substantially less than the weight of a club head for soft strokes on a golf club for conventional soft blow. In the right proportions, that improvement in the golf clubs for soft strokes incorporated the complicated variables of the point of balance, the center point of the means of weight, the weight of balance, and the means of the weight in a certain way, such as to achieve and maintain the wrist's immobility potential and inhibit head control while maintaining touch, speed, and play associated with the club for conventional soft strokes. The intricate interaction of the variables results in a substantial increase in the total weight of the golf club for soft strokes with a corresponding, and still drastic reduction in the balance weight. The improvements of that invention as it relates to golf clubs for soft strokes, promotes a smooth, fluid, uninterrupted stroke for the duration of the soft stroke. It has been found that these same characteristics (wrist immobility potential) are also achievable by varying grades, using even less weight than the previously used, while using variable head weights higher than the weight of a golf club head. for conventional soft blows. This graduated approach not only supports the immobility of the wrist, but with a "heavier head" in relation to the added weight, reintroduces an element of the control of the head emulating "fictitiously" by this the touch of a traditional soft stroke stick. The psychology of that "touch" together with the "immobility of the wrist" increases the efficiency of a blow and a soft blow. SUMMARY OF THE INVENTION The problems noted above, and others, are overcome by the improved soft-stroke club, which has a counterweight especially to alter the point of balance by increasing the total weight of the club for gentle strokes by means of which the ratio between the club head for soft hits and the total weight and balance weight are altered in such a way that the wrist's immobility potential is achieved and maintained, and limited head control is reintroduced, for the duration of the soft hit. The improved soft-hitting golf club includes a handle with an inner camera, a handle attached to the handle from a stop down, a club head for soft hits connected to the handle in a cap, and an additional weight of a predetermined amount located along the handle of the golf club for soft strokes at a predetermined location based on the center point of the weight to add weight substantial to the total weight of the golf club for improved soft hits as it relates to the total weight of a golf club for conventional soft hits. The proper placement of an additional weight is critical since the improved club-beat balance point falls within certain predetermined ranges in relation to the full length of the club for smooth strokes. Such additional weight, properly placed, substantially increases the total weight of the golf club for soft strokes and drastically alters the weight ratio of the golf club head for smooth goals to total weight, while simultaneously and significantly altering its weight of balance, promoting through this the immobility potential of the wrist and allowing limited control of the head. For the purpose of this invention and only for your better understanding and not limiting this, the improved soft-stroke club will be compared to a conventional soft-stroke club. A conventional soft stroke golf club is a total length of about 30 to 40 inches and weighs between 450 and 520 grams. On a golf club for soft strokes with a hosel, the length of the handle is between 30 and 40 inches. From the range of weight described above, the head of the golf club for soft strokes weighs between 300 and 340 grams, and the diverse material which includes the handle (between 85 and 95 grams), the handle (between 60 and 70 grams), and additional material (between 5 and 15 grams) of approximately between 150 and 180 grams (average of 165 grams). The average ranges of this conventional soft-stroke club are used in order to establish a base related to the present invention (i.e., a conventional soft-stroke club with counterweight of approximately 485 grams total, of which the head of the stick for soft strokes weighs approximately 320 grams, the handle approximately 90 grams, the handle approximately 65 grams, and the diverse material approximately 10 grams; and being of a total length of 35 inches and, in those golf clubs for soft strokes with a hosel, it has a 32-inch handle). The weight ratio between the club head for soft hits and the total weight in this conventional soft-stroke club is 0.66: 1. All% of length used in the present for purposes of ratio are compared with the total length of the conventional soft hitter defined above; that is, 35 inches. The balance point of this conventional soft-stroke club is approximately 26 inches from the top (74.3% length from the top) and has a balance weight of approximately D-0. In order to achieve and maintain the wrist's immobility potential and control of the head, the improved soft-stroke golf club can vary in total weight between approximately 505 and 1055 grams (when using a head weighing 240 grams and adding 100 grams, and using a head of 320 grams and adding 570 grams, respectively); the range in the proportion of the weight of the head to the added weight is between approximately 0.56: 1 and 3.20: 1; and it varies in the proportion of the weight of the head to the total weight between approximately 0.30: 1 and 0.55: 1. The aggregate weight media must be placed in a location such that the center point of the weight medium is at a distance from the top of the handle between 20 and 71.4% of the length of the total length of the stick (or between 7 and 25 inches of the same in relation to a golf club for 35-inch soft hits), resulting in a substantial alteration of the balance point (which in the conventional soft-stroke club is 74.3% in length from the top ) and an alteration of the balance weight. It is crucial to this inventive concept in relation to a conventional soft stroke stick, to reduce the proportion of the weight of the head to the total and to add weight in such a way as to alter the point of balance of the golf club for soft strokes ascending towards the top. As a means of comparison and using the weights and measures of the club for conventional soft strokes defined above, good results of the immobility of the wrist and the head control are achieved by using a weight of the club head for soft strokes of about 240 grams, diverse standard material of approximately 165 grams, and by adding weight from about 100 to about 160 grams, producing a total weight of approximately between 505 and 565 grams. When using approximately 100 grams, there is an increase in weight (above the average weight [485 grams] of a club for soft hits) of approximately 4.1%, a proportion of the weight of the head to the weight means of approximately 2.4: 1; and a proportion of the head weight to the total weight of about 0.47: 1. By placing the center point of the weight means about 7 inches from the top (20% length from the stop) results in a balance point of approximately 21.38 inches from the top (approximately 61.09% of length from the top) and a balance weight of approximately B-7 negative. Placing the center point of the same weight means about 11 inches from the top (31.4% length from the top) alters the balance to approximately 22.13 inches from the top (approximately 63.23% length from the top) and changes the balance weight to approximately Bl negative. Moving the center point of the same weight means to approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 22.81 inches from the top (65.17% length from the top) and modifies the balance weight to approximately A-4 negative. When using approximately 160 grams, there is an increase in weight (above the average weight [485 grams] of a stick for soft hits) of approximately 16.5%; a ratio of the weight of the head to weight means of approximately 1.5: 1; and a ratio of head weight to total weight of about 0.42: 1. Placing the center point of weight means about 7 inches from the top (20% length from the top) results in a balance point of approximately 19.88 inches from the top (56.80% length from the top) and a weight of balance of approximately C-6. Placing the center point of the same weight means about 11 inches from the top (31.4% length from the top) alters the balance to approximately 20.88 inches from the top (59.66% length from the top) and change the balance weight to approximately negative B-4. Moving the center point of the same weight means approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 21.75 inches from the top (62.14% length from the top) and modifies the balance weight to approximately A-3 negative. Similar results of wrist immobility and head control can also be achieved by using a clubhead weight for soft strokes of approximately 320 grams, standard miscellaneous material of approximately 165 grams, and by adding weight of approximately 100. and 570 grams producing a total weight between approximately 585 and 1055 grams. When using approximately 100 grams there is an increase in weight (above the average weight [485 grams] of a stick for soft hits) of approximately 20.6%; a proportion of the weight of the head to weight means of approximately 3. 20: 1; and a ratio of head weight to total weight of about 0.55: 1. By placing the center point of weight means about 7 inches from the top (20% length from the top) results in a balance point of approximately 23.19 inches from the top (66.26% length from the top) and a balance weight of approximately B-6. Placing the center point of the same weight means about 11 inches from the top (31.4% length from the top) alters the balance to approximately 23.75 inches from the top (67.86% length from the top) and change the balance weight to approximately C-4. Moving the center point of the same weight means approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 24.25 inches from the top (69.29% length from the top) and modifies the balance weight to approximately D-0. When using approximately 160 grams, there is an increase in weight (above the average weight [485 grams] of a stick for soft hits) of approximately 33.0%; a ratio of the weight of the head to weight means of approximately 2.00: 1; and a ratio of head weight to total weight of approximately 0.50: 1. Placing the center point of weight means about 7 inches from the top (20% length from the top) results in a balance point of approximately 21.69 inches from the top (61.97% length from the top) and a weight of balance of approximately A-9. Placing the center point of the same weight means approximately 11 inches from the top (31.4% length from the top) alters the balance to approximately 22.75 inches from the top (65.0% length from the top) and change the balance weight to approximately C-0. Moving the center point of the same weight means to approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 33.50 inches from the top (67.14% length from the top) and modifies the balance weight to approximately D-1.5. When using approximately 570 grams there is an increase in weight (above the average weight [485 grams] of a stick for soft hits) of approximately 117.5%; a ratio of the weight of the head to weight means of about 0.56: 1; and a ratio of head weight to total weight of about 0.30: 1. Placing the center point of weight means about 7 inches from the top (20% length from the top) results in a balance point of approximately 16.00 inches from the top (45.71% length from the top) and a weight of approximately negative E-9 balance. Placing the center point of the same weight means about 11 inches from the top (31.4% length from the top) alters the balance to 18.25 inches from the top (52.14% length from the top) and changes the weight of balance to approximately A-4 negative. Moving the center point of the same weight means to approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 20.50 inches from the top (58.57% length from the top) and modifies the balance weight to approximately D-6. Better results of wrist immobility and head control are achieved by using a club head weight for soft strokes of approximately 260-290 grams, standard miscellaneous material of approximately 165 grams, and by adding approximately between 100 and 160 grams producing a total weight between approximately 525 and 615 grams. When using approximately 100 grams as a means of weight with approximately a club head for soft strokes of 260 grams, there is an increase in weight (above the average weight [485 grams] of a club for soft hits) of approximately 8.2%; a ratio of head weight to weight means of approximately 2.60: 1; and a ratio of head weight to total weight of approximately 0.49: 1. By placing the center point of weight means about 7 inches from the top (20% length from the top) results in a balance point of approximately 21.81 inches from the top (62.31% length from the stop) and a negative balance weight of approximately A- 9. Placing the center point of the same weight media approximately 11 inches from the top (31.4% length from the top) alters the balance to approximately 22.63 inches from the top (64.66% length from the stop) and change the balance weight to approximately negative A-2. Moving the center point of the same weight means to approximately 15 inches from the top (42.9% length from the top) changes the balance point to approximately 23.81 inches from the top (68.01% length from the top) and modifies the balance weight at approximately A-5. When using approximately 160 grams as a means of weight with a club head for soft strokes of approximately 260 grams, an increase in weight occurs (above the average weight [485 grams] of a club for soft hits) of approximately 20.6%; a ratio of head weight to weight means of approximately 1.63: 1; and a ratio of head weight to total weight of about 0.44: 1. By placing the center point of weight means about 7 inches from the top (20% length from the stop) results in a balance point of approximately 20.38 inches from the top (58.29% of length from the top) and a balance weight of approximately B-7 negative. Placing the center point of the same weight means approximately 11 inches from the top (31.4% length from the top) alters the balance to approximately 21.38 inches from the top (61.09% length from the stop) and change the balance weight to approximately A-5 negative.

In accordance with the foregoing, several objects and advantages of the invention are also: increase the fluidity and continuity of a roll practice practice hit; get and maintain the immobility potential of the wrist for the duration of the blow; reintroduce head control limited to hit; Counterbalance the weight of the club head for soft hits and the weight of the top, so that neither the club head for soft hits nor the top weight take full control of the hit; oppose the physical impediments to the successful termination of a soft stroke; keep the shoulders as the fulcrum and the main force when pushing a soft blow; neutralize the voluntary and involuntary movement of the wrist during the execution of a soft blow; maintain the tact and speed expected as those of a golf club for conventional soft blows; and to improve the general mechanisms of a shot practice practice. Other objects and aspects of the invention will be apparent when the drawings that follow are understood upon reading the corresponding description thereof. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an elevation view, partly in axially sectioned, of a golf club for soft strokes of this invention having internal weight means. Figure 2 is a cross-sectional view showing a structure of alternative internal weight means of this invention. Figure 3 is an exploded elevation view, partly in axially sectioned manner, of an alternate embodiment of the golf club for soft strokes.
DESCRIPTION OF THE PREFERRED MODALITIES Figure 1 is an elevation view and, for clarity, is not to scale. This discloses a cross section in partial axial cuts of a golf club for soft strokes 10. The golf club for soft strokes 10 has in general a tubular handle 12. The handle 12 can be sharpened in parallel, or any combination thereof. The handle 12 has an inner chamber 14, a stop 16 and a bushing 18. The inner chamber 14 has walls 13. From the stop 16 to the bushing 18, in this mode, the handle 12 is sharpened. The handle 20 is held in and down the stop 16 of the handle 12. The head of the golf club 22 is connected to the sleeve 18 of the handle 12. The weight means 24 is placed in the inner chamber 14. The first plug 28 and the second plug 30 clings fixedly to the walls 13 and rests on the opposite sides of the weight means 24 to securely hold the weight means 24 in place. The plugs 28 and 30 are made of a material of substantially low density, but are not limited to capping, or other similar material suitable for the intended purpose. A single plug or more plugs can be used depending on the selected materials. If a single plug is used, it must be located in the position of the first plug 28. The weight means 24 has a central point 26, which represents the point at which the weight is equal on either side thereof. The means of weight 24 may consist of a single piece or of a plurality of pieces. The material for weight means 24, includes, but is not limited to, lead, copper, bronze, zinc, steel, depleted uranium, and mixtures thereof; or other material of sufficient density suitable for the intended purpose. Optimal results are achieved with lead due to its cost, malleability, availability, and density. Lead provides the best means of weight for the appropriate length, center point, point of balance, and distance of the stop to achieve the appropriate weight balance and firmly establish and maintain the desired immobility potential of the wrist during practice of the rolled play. The balance points 23 and 25 reflect the different locations and intermediate points as both the weight means and the center point are altered. Figure 2 is an axial cross-sectional view showing an alternative for the weight means 24. The weight means 24 here comprise a plurality of small particles 32 held in place by the first 28 and second 30 plugs, each of which it is fixedly supported on the walls 13 of the inner chamber 14. The small particles 32 include, but are not limited to, lead, copper, bronze, zinc, steel, depleted uranium, high quality and mixtures thereof; or another material of sufficient density suitable for the purpose pursued. The small particles 32 can be gravitationally supported with one another or absorbed by a security component 34 so that they can be held in place. The security component 34, if used, seals the points 31, the points at which the plugs first 28 and second 30 rest on the walls 13 of the inner chamber 14. The security component 34 keeps the small particles 32 and the plugs first 28 and second 30 securely in place and provides cushioning support for the small particles 32 within the inner chamber 14 thus facilitating a smooth stroke in the practice of the rolled play. The security component 34 comprises, but is not limited to, natural and synthetic rubber, epoxy, polyester, resin, and mixtures thereof; or other components suitable for the purpose pursued. The means of weight 24 can be fluid or liquid of sufficient density suitable for the purpose pursued. Such fluid includes, but is not limited to, high density oils, mixtures of high density oils and other liquids or solid particles, and combinations thereof. The security component 34 is adapted to act as a shutter around the plugs 28 and 30 to prevent leakage of fluid within the handle 12. Figure 3 is an exploded elevational view, in axial sections, of an alternative assembly of golf club for soft punches 110. The handle 112 has an inner chamber 114, a stop 116, and a bushing 118. The club head for soft strokes 122 is connected to a bushing 118. The handle 120 is attached to the handle 112. The inner chamber 114 has walls 113. In this embodiment, the handle 112 has substantially parallel sides 121, which extend from the stop 116 to a distant point in a single stopper 128. In the preferred embodiment of the golf club for soft strokes. 110, the length of the handle 112 is approximately 33 inches and the total length of the golf club for soft strokes 110 is 35 inches. The length of the parallel sides 121 is about 16 inches. The parallel sides 121 can pass through the entire length of the handle 112. The weight means 124 can also be in one piece or in a plurality of pieces. The center point 126 of the weight means 124 is the point at which the weight of the weight means 124 is the same on either side of the center point 126. The weight means 124 can be of any suitable material for the purpose that is pursues including, but is not limited to lead, copper, bronze, zinc, steel, and depleted uranium, and mixtures thereof; or other material of sufficient density adequate for the purpose pursued. In this preferred embodiment, the center point 126 of the weight means 124 is approximately 11 inches from the stop 116. The total length of the weight means 124 in this embodiment is approximately 7% inches and is of sufficient width, diameter, or perimeter such that this substantially fills the walls 113 of the inner chamber 114. A single plug 128 is located on the handle 112 and secures the weight means 124 in place. The location of the center point 126 of the weight means 124 for golf clubs for soft strokes of greater or lesser lengths will be increased or reduced proportionally in distance from the stop 116 in relation to increase or reduction in the length of the golf club for soft blows Increases or reductions in proportional weight should be made in relation to changes in weight. The proportions of the weight (from the weight of the club head for soft strokes to the total weight and the weight of the club head for soft strokes to weight means) and the balance points are crucial for this improved stroke club. by achieving and maintaining the immobility potential of the wrist while simultaneously allowing limited head control.
In the soft-stroke club 110 shown above with a handle 112 having a length of approximately 32 inches (total length of the club for 35-inch soft strokes, the total weight of the club for soft strokes of 485 grams. ) optimum results are achieved by attaching the handle 112 to the clubhead for soft hits 122 having a weight of approximately 320 grams (approximately equal in weight to the weight of a conventional soft-stroke club) and adding weight means of approximately 290 grams, for a net weight gain of approximately 290 grams or approximately 59.8% of the weight over that of the conventional pre-defined conventional soft-stroke club. This example produces a ratio of weight between the club head for soft hits and the total weight of the club for improved soft hits of approximately 0.41: 1 and a weight ratio between the club head for soft hits and the weight means added approximately 1.10: 1. The center point 124 for the added weight (weight means) is approximately 11 inches (31.4% in length) from the stops 116. This mode facilitates the execution of a more perfect soft stroke by altering the closest upward balance point to the top 116 on the handle 112, or approximately 20.81 inches (59.46% in length) from the top, where the golfer's hands try to hold the golf club firmly and stably, and yet still allow some control of the head . This performs a B-2, better balance weight, suitable for the optimal immobility potential of the wrist and limited head control. These proportions lighten the tension of the hand caused by using a conventional soft stroke golf club, its weight being completely concentrated on the club head for soft strokes and it distributes more weight near the region of grip and control of the golf club. soft blows, thus bringing the point of balance closer to the focal point of the blow and allowing some control of the limited head to effectively emulate the "touch" of a conventional soft-stroke stick while maintaining the immobility potential of the wrist. By altering the point of balance in such a way and achieving the optimum balance weight, the immobility potential of the wrist is achieved and keeps encouraging the soft, fluid, and uninterrupted blow. While specific embodiments of the improved soft-stroke club have been shown and have been explained above for the purpose of illustration, it should be understood that many other uses will be found for the exposition of the present invention and various alterations, modifications and modifications may be made. substitutions thereto, without departing from the spirit and scope of this invention as defined by the appended claims. Which is intended to be included within the scope of the invention. According to the foregoing, the scope of the invention should not be determined by the illustrated modes, but by the appended claims and their legal equivalents.
