Abstract

The invention relates to a golf putter which is intended to eliminate all wrist movements. The design of the inventive club, the specific shape of the hosel thereof, which can be adjusted along deployment and rotation axes, and the start point of said hosel all combine to force the golfer to use the putter with his/her wrists positioned in front of the club such that the wrists can no longer be moved. In this way, the ball can only go in the direction generated by the shoulders and back, thereby guaranteeing greater putting precision.

Description

A GOLF PUTTER

The present invention relates to a putter: that is to say a golf club intended to bring (putter) the golf ball into the hole when it is at a short distance from it. Such a club is generally made up of a head connected to a shaft by a hosel which starts from the heel.

The configuration of the club determines the (technical) way of using the club as well as the advantages and disadvantages associated with it. It is important to know what the goal is for the golfer. Through the execution of the gesture (putter), the goal, which is also the greatest difficulty, is to hit (putter) the ball so that it advances as straight as possible to make it fall into the hole. Note the great importance of these golf shots (puts) in a game. The design of such clubs (putter) generates right or left effects (also called wrist shots) given on the ball resulting in missing the hole.

Other solutions have been proposed to eliminate the risks of wrists: patent (A63B 53/02, WO 95/01819) in this case the author of the patent seeks to give acceleration to the ball thanks to the effect of traction or patent (A63B 53/04, WO 98/29164) here the author proposes a solution by pushing the mass of the head of the club which has the disadvantages less precision in the direction given to the head of the club, we can more easily understand this lack of precision with the image of a dog sled, it is as if the dogs were placed behind the sled. In both cases the authors of the patents sought to play with the hands in front of the putter. Patent (JP 2000 061013A) Kl MURA TSUNEHISA here the author seeks to give more precision in his put by diverting the departure of the hosel in order to make the best use of the force of inertia due to the natural gravity of the Earth. Patent (US 5782 705 A) SOLARI in this case the author uses a one-piece shaft (and which does not have a hosel) which also goes backwards and then goes back forward but whose starting point part of the heel like a classic putter so as it stipulates in claim 3 it is provided with a long shaft which arrives at the top of the shoulder, and a head whose width is at least equal to 5 or 6 inches (a minimum of 12 cm). Like me the author of the patent seeks to play the handles forward so as to follow the head of the putter an imaginary straight line going in the chosen direction but the solutions provided in the invention presented above are different by its design because the solution that I propose is an adjustable hosel which can adapt to any it club head and any type of shaft (course or other) and all types of players, the hosel is composed of three parts going in different directions having the effect of using other factors strengths.

The design of the putter allows the ball to advance as straight as possible. The proposed putter allows to give a trajectory to the movement (putter) naturally straight, because the wrists are in front of the club (in the direction of play). As a result, wrist shots are suppressed, the player uses the natural pendulum of his shoulders and back so the accuracy of the trajectory of the ball is increased. Note that the model presented here is a right-handed club. It goes without saying that for a left-handed club all the benchmarks are reversed.

The main characteristic of the invention comes from the shape, from the different directions of its hosel, from its starting location (the start is in the front quarter of the point, then leaves towards the back of the club to then leave towards the front) it is composed of three parts and the fact that the hosel can be adjustable in deployments and rotations. To define the different directions and angles of the room I use three axes, x which is the width, y which is the height and z which is the depth. Figure 1 is a left side view, it is the projection of parts (2), (21) and (9) on the plane defined by the axes y and z; the hosel is composed, in its center, of the part (2) which forms an acute angle with the axis of the z, at one of the ends the part (21) forms a right angle with the axis of the z .. A the other end of the part (2) is joined the ferrule (9) (hollow part allowing the shaft to be fixed to the support (lθ)) so that it forms an obtuse angle with the axis of the z. Figure 2 is a front view, it is the projection of parts (2), (21) and (9) on the plane defined by the axes y and z; the hosel is composed, at its center, of the part (2) which forms an acute angle with the x-axis, at one of the ends the part (21) forms a right angle with the x-axis. At the other end of the part (2) is joined the ferrule (9) so that it forms an acute angle with the x-axis. Figure 3 is a top view is the projection of parts (2) and (9) on the plane defined by the axes z and x; the hosel is composed, at its center of the part (2) which forms an acute angle with the x-axis. In this plane the part (21) figure n ° l which is at one of the ends does not appear on figure n ° 3, this indicates that this part is perfectly perpendicular to the axis of y. At the other end of the part (2) is joined the ferrule (9) so that an acute negative angle is formed with the x-axis. By these three figures n ° 1,2,3 are defined all the directions as well as all the angles of the hosel. In addition, a variant of the realization of the hosel can indeed, for practical reasons, be entirely mobile, in order to immediately and durably achieve very precise adjustments for each player (so that the club adapts to the way of playing of each player and not the reverse like all the other current clubs). Figure 7 and Figure 8 is a front view of the hosel, it highlights the different movements, deployments or rotations of the adjustable hosel. The shaft (10) is fitted on the ferrule (9) can have a deployment of approximately 90 ° from the Y axis to the X 'axis on the axis of rotation Q' connecting the ferrule (9) with the part (B). The movement of the ferrule (9) and the part (B) on the part (C); the parts (9) and (B) connected together by the axis of rotation Q 'can have a 360 ° rotation on the part (C) along the axis XX' and this in both directions. The movement of the part (21) on the part (C); the part (21) can have a deployment of approximately 90 ° from the Z axis to the X axis on the axis of rotation Q connecting the parts (21) and (C). The movement of the club head fitted at the point (1) on the part (21) can have a rotation of 360 ° on the Z axis and this in both directions. The shape of the hosel offers several advantages: the first is to be able to play the club with the hands forward, the second to see the ball when one is at the address. The third is to exercise both the mass of the club head; thanks to the location of the hosel on the front of the club head (for steering precision), since the golf club is pulled forward and a push since the force restored to the club head arrives from the back of the club head (for more precision in the dosage of force), is added to the main feature, the starting location of the hosel on the club head. Until now, the hosel was attached to different points of the head of the club none of them started the hosel from the part of the club head called the point of the club figure n ° 2 (1). The part (21) which forms part of the hosel is fixed perpendicularly and directly in the head of the club called the point (1). This precise location in the front quarter of the point allows at least three known advantages, the first to avoid that the club turns in the hand in contact with the ball; the second makes it possible to obtain in the execution of the gesture of putter a traction (because one pulls the mass of the head of the club forward). The consequences of traction are: very high precision in the direction given to the head of the club, the third is to have a better angle for the attitude of the head when one is at the address.

The second characteristic resides in the shape of the putter which has a simple geometric base, for example a pyramid. To define the first triangle of the pyramid I use Figure 3, it is a partial sectional view from above. The hatched part (3) is the sectional view of the pyramid, the symmetrical part without hatching represents the end of the pyramid: having as an isosceles triangle, the shortest side of which serves as the front, figure n ° 2 (3) , putter. The definition of the second triangle is shown in figure n ° l, it is a partial section view of the left profile, the hatched part (3) is the partial section view of the pyramid, it is an isosceles triangle whose side different from the other two is used to face the putter, figure n ° 2 (3). Figure 2 (3) shows a partial front view of the base of the pyramid. Each geometric shape has its own resonance; it is this property which is applied. Other geometrical shapes can be applied such as for example a star base with 6 branches figure n ° 4. Then, this pyramidal base is completely or partially covered (only to form the sole figure n ° l (7)) of the same material or a different material (metallic, transparent, translucent or other) of the pyramid to have the set of the back of the oval-shaped club head, figure n ° l (4). In order to more easily slide the club on the course during its use.

The third characteristic resides in the insert, which can be of any shape: like for example, a disc appears n ° 2 (5), which is fixed in the center of the base of the pyramid (3) or a cone, a square, a rectangle, a rhombus or other (resonance of the form because each form has its own resonance) and which can also be made up of different materials, natural or artificial, smooth, rough, spongy, which can be chosen by the player according to the desired needs (flexibility, hardness or other) in contact with the ball.

By its simple shape figure n ° 5, n ° 6 and by the originality of its design, this club allows an optimum efficiency in its design. If we consider the top view (wide shot) of Figure 5, we can see that the grip (11) and the shaft (10) are well in front of the club head; and it is for this reason that the player must hold his wrists forward if he wishes to use the club correctly. It is by playing the wrists forward that the player eliminates all wrist movements harmful to his game. In addition, such a position makes it easier to use the inertia of his body for more precision in the dosage of the force (for the distance from the puts). Thanks to the shape of his hosel, the player is not embarrassed to see the ball in the execution of his movement despite the starting location of the hosel as well as the direction given to the shaft which leaves on the front of the club. Moreover by the adjustable design of his hosel he is currently the only putter to adapt to the way of putter of each player and not the reverse, it is custom-made immediately. All the angles as well as all the dimensions given here are given by way of nonlimiting examples. Figure 1 shows a partial sectional view of the head of the left profile. This view allows you to see the thickness of the head and its profiled shape. We see the starting point of the hosel (2), which starts from the front of the club head, its shape as well as the different directions given by the angles formed between the central part of the hosel and the pieces ( 21) and (9). We see the location of the insert (5), the pyramid (3), the shaft (10), the ferrule (9) and the sole (7) formed by the part (4). In addition, the y and z axes are noted. Figure 2 is a front view. We can see that the insert (5) is centered in the middle of the base of the pyramid (3). We see the starting point of the hosel of the point (1) of the club (and not of the heel (6)), the shape of the hosel as well as the different directions given by the angles formed between the central part of the hosel (2) and the parts (21) and (9). As a result we see the shaft (10) return towards the player. The part (7) shows the sole of the club. In addition, the y and x axes are noted. Figure No. 3 shows a partial sectional view from above, tight plan on the head of the club; it aims to have a more detailed view of the head of the club in order to clearly see the starting point of the hosel (2) of the tip (l) (part opposite the heel (6)). The directions of the hosel (2): the angle formed between the central part of the hosel and the part (9). We can see the shape of the pyramid (3), the location of the part (4), the location and depth of the insert (5) and the direction of the shaft (10) which starts at the front of the club. In addition, the axes of z and x are noted. Figure 4 shows a top view of another example of geometric shape, it is a star base. Figure 5 shows a top view with a wide plan, which allows a better understanding of the general shape of the putter as well as its normal positioning in the way it is played. We see well ; the shaft (10) start on the front and the positioning of the grip (11) at the opposite end of the shaft, the heel (6) and the toe (1) are opposite, the starting point of the hosel as well as its central part (2), the pyramid (3) and the shape of the part (4) seen from above. Figure 6 shows a three quarter left view of the finished putter.

Figure No. 7 is a front view of the hosel adjustable in rotation and deployment, are clearly marked the parts constituting it. The ferrule (9) and the part (21) surround the parts (C) and (B), as well as their axes of deployment Q AND Q 'and their axes of rotation Z, XX' and other Y.

FIG. 8 is a front view of the adjustable hosel with its starting location in the head of the club going from the point (1), showing the successive interlocking of the parts (21), (C), (B ), the ferrule (9) and the shaft (10), at the heel (6). We also see another example of insert shape (5).

By way of nonlimiting example, the putter will have these dimensions: The pyramid: the dimension of its rectangular base is 32 mm by 84 mm and 63 mm in height The insert: has a dimension of 21 mm in diameter and 10.5 mm in thickness

The hosel: has a diameter of 52 mm; the first part which enters the tip at a length of 32 mm, the second part which goes back at a length of 42 mm and finally the third part with the ferrule has a total length of 21 mm.

The shaft: has a diameter of 52 mm at the base which enters the ferrule, 1040 mm in length, and has a diameter of 104 mm at its top. The piece (4) has a thickness of 32 mm, a length of 84 mm and a width of 63 mm.

The first step is the one-piece molding of the pyramid in figures 3, 4 and 5 (3), the hosel in figures 3, 4 and 5 (2) and the ferrule in figures 3, 4 and 5 (9) without the insert.

The second step is the creation of the insert in Figures 4 and 5 (5) by molding or machining.

The third step is the insertion of the insert in Figures 3, 4 and 5 (5) into the pyramid in Figures 3, 4 and 5 (3) by gluing or stamping.

The fourth step is the molding of the part (4) Figures 3, 4 and 5 directly around the assembly formed between the first three steps.

Thus, at the start of the fifth stage, the head of the club is finished. It only remains to add by gluing the shaft Figures 3, 4 and 5 (10) to the ferrule Figures 3, 4 and 5 (9).

The sixth step is the fixing of the grip figure 2 (11) on the shaft figure 2 (10) to give a finished product.

Industrial application can be done by mass molding.
