Abstract

Plastic or conglomerate of the head (1) is an integral, load-bearing structure. The shaft (2) is fastened in a bore close to the face (11). The head is balanced about an axis (Y) defined by the shaft.

Description

The invention relates to a golf putter with a Shaft and one located at one end of the shaft a striking head with striking surface, which in essentially made of plastic or a conglomerate high plastic content, as well as handling a golf putter, especially the aforementioned.

With the putt method used so far, the putter held with both hands. Which hand above the other Hand placed on the putter grip is individual. This also applies to straight or angled ones Arms as well as for fixed or playing wrists. Thus, for putting success, putting is a fine motor coordinated biomechanics and an absolutely secure grip crucial. In addition, the golfer stands by this Putt method essentially perpendicular to the putt line. With a sideways rotation of the head you can completely wrong assessments arise. The golfer must therefore first get behind the ball make a spatial picture of the course of the putt line to record distance and stroke speed to estimate. The golfer must have these impressions now notice to take the game posture. Overall, this creates great uncertainties and resulting failures.

An attempt was therefore made to ensure accuracy Optimize improvements to the golf putter.

Golf putter with an essentially plastic existing head are for example from the US 5,782,706 known. The impact head comprises a polymeric one Resin body, which as a composite with a weighted, completely enclosed mass is. The weighted mass typically exists made of metal. To secure and permanent attachment to reach the striking head on the shaft is the lower one End of putsch in weighted mass attached.

However, it is disadvantageous that the production of the putter head is expensive and possibly detachments between the weighted mass and the surrounding resin mass occur.

These improvements result in conventional putters but not to a higher accuracy, so remain the basic problems mentioned at the beginning the usual two-handed put technique.

An alternative put technique is therefore being sought with a frontal posture aligned with the putt line to develop. Some golfers have the ball for example with a pendulum movement of the golf putter beaten between the legs. This put technique results however, also no casual hand and arm posture. Furthermore, such putting is not in accordance with the rules.

In addition, the difficulties of everyone remain ambidextrous Put technology, mainly from the biological predetermined dominance of one hand / arm / body side (Right-handed / left-handed) when checking the Sequence of movements.

From US 5,454,464 is a putter for a one-armed Known use in which the putter head is eccentric is provided with the shaft, the shaft in lower part is bent so that the shaft of the putter head first away from the golfer's body and then going back to the body so that the Handle element essentially perpendicular above the center the striking head is aligned. To handle the Putters faces the golfer with his face and uses the natural pendulum movement for the putting process of the arm, which is essentially parallel to the Finish line should be done. This is due to the elaborate Shaft design and inclination of the shaft in one Angle to the vertical directed backwards from 10 ° to 40 ° and inward from 5 ° to 15 ° become.

The disadvantage is that the shaft for ergonomic reasons must experience a high level of processing, in particular because the entire pendulum movement of the putter head it is implemented via the shaft design. On Another disadvantage is the exact geometry of the handle, which the ergonomic conditions of a capture every golfer or to the physical Conditions must be specially adapted. In addition is any ergonomic help is illegal.

Starting from the one described in US 5,454,564 Put technology is therefore an object of the invention for to indicate the one-armed putt trained golf putter, which is easy to manufacture and with its Handling generates high accuracy. Furthermore, it is Object of the invention, the one-armed put technique improve.

This task is solved with a putter according to Claim 1 and a putt method according to claim 9.

The fact that the impact head made of plastic or Conglomerate formed in one piece as a load-bearing component and in it the shaft in a shaft receiving bore is attached near the face, the Striking head balanced to the axis defined by the shaft is a plastic or plastic conglomerate homogeneously producible impact head specified in which the shaft directly in the plastic is attached. The one made of one material Striking head can thus be finished and finished in one pass be prepared for the socket. Striking head and shaft are arranged so that the Striking head balanced to the axis defined by the shaft is, d. H. the center of gravity of the striking head with horizontal alignment of the face vertically below that defined by the shaft Axis lies. This ensures that with one-handed / one-armed Handling the golf putter none that Torques influencing target alignment during putting stroke act on the wrist holding the putter. The one behind the stock pick-up point when struck The center of gravity of the striking head stabilizes the golf putter even when shifted to the center line of the putter Point of impact of the ball on the putter what also leads to higher accuracy.

In another embodiment, it is advantageous if the striking head is essentially semicircular has, the semicircular disc interface is level and the face of the Striking head forms. Such a shape of the striking head is inexpensive to manufacture and offers a good concentration on a stable, large face the head mass to the center of the head. Deformation on the face of the usual stress on the impact head there are not too fear.

The fact that the sole of the striking head Semicircular surface is convex, is characterized by the arched bottom of the sole an undesirable snagging of the striking head avoided in the grass. If that's the top of the striking head forming semicircular surface from the Face to the back of the head in one Angular range falling from 0 ° to 20 ° to the horizontal is inclined, the impact head mass gets closer, however still concentrated behind the socket. The required stability of the energy transfer Striking head is retained.

The fact that at least one in the sole area of the Striking head embedded in the plastic body Additional weight is provided, the additional weight a higher density than the plastic body of the Striking head, will fine tune the Weighting of the golf putter enables. Furthermore, by providing the additional weights in the sole area of the Center of gravity of the striking head closer to the sole area postponed what the desired energy transfer optimized when hitting the golf ball to be hit. To balance the striking head in particular to improve the axis defined by the shaft, are two made of metal, preferably brass Additional weights on both sides of those due to the surface normal the focal plane spanned the face and the shaft intended. The made of brass Additional weights have a relatively high density, one for the loads on impact are of sufficient strength, can be manufactured cost-effectively as an automatic turned part and are not susceptible to corruption.

If on both sides of the top of the impact head by the surface normal of the face and the Spanned focal plane equally spaced Target marks are arranged, the Gaze and target motor skills when addressing and aligning supported the ball.

Due to the parallel alignment of the shaft The striking surface is the one-armed posture of the Golf putter created extension of the game arm the shaft can be experienced directly on the face transfer. To simplify operation, the Shank has a slight inclination to the axis of symmetry or Semicircular disc axis of the striking head from 0 ° to 15 ° on. To comply with the international golf rules, must the angle greater than or equal to 10 °, here preferably 10.1 ° his.

If the striking head consists of a homogeneous conglomerate of polyoxymethylene graphite Ms 58 with a specific density of approx. 1.4 (density of 1.4 g / cm ³ ), a golf putter with a particularly sensitive action is provided in the one-armed putt method. The striking head made of the homogeneous conglomerate predictably transfers its energy from the pendulum movement when it hits the golf ball. The ball speed required to punch on the green can thus be ideally predetermined.

The procedural task mentioned at the beginning is at a putting method where the golfer uses the putter holds with one hand on the shaft, solved by the fact that the upper end of the putter shaft on the forearm is present, with an extension over the putter shaft of the play arm on the striking head (arm-putter system) is formed and the blow by a Pendulum movement of the arm putter system in the target direction is performed.

Because the upper end of the putter shaft on the forearm an arm putter system is formed that a harmonious, over the ball joint of the upper arm too controlling motor unit results. The motor skills of Pendulum movement during putting corresponds to everyday motor skills of the corresponding arm when walking, with what a very simple and well-known sequence of movements when Putting is to be carried out. So this is targeted Movement sequence can be learned quickly and leads quickly to high marksmanship.

If the golfer is essentially head-on to the target stands next to the ball and from this position the free, easy pendulum movement of the arm-putter system is the golfer's field of view and the face of the putter head frontally-horizontally on the three-dimensionality of space, namely green, of the hole and the putt line. To read The golfer needs the location on the putt line not to be changed, so that even with a test movement the eye motor functions as a supervisory authority, since the Field of view and the putter's hit area form motor, sensory-physiological unity. As a result, marksmanship is further improved.

A particularly immediate extension of the commuting Punch arm in the arm putter system is achieved when the putter on the grip area of the shaft between the thumb and fingers of the hand is held. Thereby at Golfers the physiological impression creates that the putterhood is the artificial extension of the stretched Thumb and index finger, the putter head die fingers clenched into a fist, the target area of the putter head with the hand hanging down Thumb nail and the volume of the putter head to the Fist hand clenched fingers. Out of it with the arm extended, there is a harmonious, extraordinarily stable, organic compound that Golfers have a high level of security and control mediated.

This harmonious and stable connection in the arm putter system is further increased by the fact that the free end of the shaft through the furrow between the thumb hill and Little finger hill of the hand is guided and over the Elbow joint on the underside of the upper arm muscle ends.

Marksmanship is achieved by laying on the forearm of the free arm on the back further improved because of that here the kinematic chain is closed, with what unnecessary balancing of the free arm is eliminated.

In Fig. 1 a putter head 1 is shown in front view. The putter head 1 has an essentially semicircular disk shape as in particular from FIG. 3 and 4 is recognizable. The semicircular disc interface forms the face 11 of the striking head 1. Die Strike or hit surface 11 is level.

In the bottom view shown in Fig. 4 is the Bottom or sole 12 of the striking head 1 shown. This sole 12 is convex, as well the front view in Fig. 1 and side view Fig. 2nd apparent to an undesirable "sticking" of the Avoid putting putter head in the grass when hitting. Out for this reason, the transition edge between the Face 11 and the sole 12 at least in the deepest Area of the striking head there as a rounded edge 13 as in Fig. 2 recognizable, formed.

Due to the semicircular disc shape of the putter head 1 the striking head 1 has no pronounced foot shape and thus with the exception of the face 11 on all sides rounded back 14. Preferably the dimension corresponds of the putter head it is half the size of a hole the green. That means the semicircular disc Putter head 1 has a diameter of 100 mm. The height of the putter head is in the illustrated embodiment 43 mm and the depth due to the semicircular disc shape of the putter head 50 mm.

Top 15 is a substantially flat, semicircular Area from the front edge to the Striking surface 11 sloping towards the horizontal is inclined. In the putter head 1 is 15 from the top a shaft receiving bore 16 in the hammer head 1 brought in. The shaft receiving bore 16 is parallel to face 11 and at an angle of 10.1 ° to Axis of symmetry of the putter head or semicircular disc axis X arranged, the bore axis Y on the the lowest point of the putter head.

In addition to the shaft bore 16, 15 are on the upper side equally spaced from the bore axis Y parallel to Target direction, that is to say oriented normal to the face 11 Target marks 17 attached. The target marks 17 are in the illustrated embodiment on both sides of the bore axis Y in one Distance of 22 now arranged. The length of the marks 17 are approx. 3 cm. The target marks 17 are designed with yellow color, for example.

In the sole area 12 of the striking head 1 there are two circular disk-shaped ones Additional weights 18, preferably made of Brass, embedded in the striking head body. With the Additional weights 18 can the putter head 1 or entire golf putter particularly precisely balanced so that when holding horizontally balanced of the golf putter on the shaft 2, for example with a Fingers, the putter head independently with its Aligning the putter surface 11 horizontally pointing upwards. Furthermore, the center of mass of the putter head by the arranged in the sole area 12 Additional weights 18 shifted downwards so that the height the center of mass for a typical stroke just above the green in about half the golf ball diameter corresponds. In addition, the additional weights an individual setting of the golf putter be made. Has in the embodiment the putter head 1 has a weight of exactly 300 g.

Schaftlänge 87 cm für Körpergröße 160 - 175 cm

Schaftlänge 92 cm für Körpergröße 170 - 185 cm

Schaftlänge 97 cm für Körpergröße 180 - 195 cm und

Schaftlänge 102 cm für Körpergröße 190 - 205 cm.

A straight shaft 2 is inserted in the shaft receiving bore 16, as shown in FIGS. 1 and 5. Possibly. a shaft sleeve 21 made of brass is first inserted into the shaft receiving bore 16, into which the shaft 2 is then inserted. The shaft 2 preferably consists of a black graphite-polymer mixture and, depending on the shaft length, has a weight of approximately 60 g. In order to adapt the golf putter to the height of the golfer, the following shaft lengths are provided:

Shaft length 87 cm for height 160 - 175 cm

Shaft length 92 cm for height 170 - 185 cm

Shaft length 97 cm for height 180 - 195 cm and

Shaft length 102 cm for height 190 - 205 cm.

Two handle elements 22, 23 are attached to the shaft 2. The grip elements 22, 23 preferably consist of a black rubber mixture and are as on the Putter shaft 2 windable sleeves, for example with a length of about 20 cm. The upper Handle 23 is located at the upper free end 24 of the Shaft 2. The handle 22 underneath is with a distance of about 4 to 6 cm below the top Handle 23 arranged on the shaft 2. Weigh the handle in the illustrated embodiment, approx. 43 g each. The The total weight of the putter varies depending on the shaft length between 443 and 463 g.

The handling of the golf putter is described below 5 described in detail.

5 shows a typical putting situation when playing golf schematically represented spatially. A golfer G holds with its dominant hand / arm / body side, right-handed here, the golf putter according to the invention 1.2. The golfer G has a casual, casual Standing with the arm slightly bent forward Upper body.

The blow arm hangs down in a casual position, the hand holding the golf putter on the lower handle 22. The thumb G1 and the index finger G2 clamp the Handle 22, with thumb G1 in the direction of impact rests on the front of the handle 22 and the index finger G2 forms the abutment behind the handle element. The The remaining fingers of the hand also grip around the handle 22. The run continues to the upper shaft end 24 End shaft 2 through the furrow between the thumb and Little finger hill. The upper handle 23 of the Shaft 2 lies along the forearms and ends above the elbow joint at the bottom of the upper arm muscle G3. The upper grip element 23 lies on Forearm and the upper end 24 of the shaft 2 or of the grip element 23 is from the bottom of the upper arm muscles limited.

The golfer G can stand up from his casual posture through the essentially frontal orientation of the body to the finish line Z the hole L without change target the game posture. The field of view of the Golf player G and the hit area 11 of the putter head frontal-horizontal to the three-dimensionality of the Space, the green, the hole L and the putt line Z aligned. A change of location to read the putt line, like with the traditional ambidextrous putt method not necessary. Even during the Trial movement by a pendulum movement of the arm putter system the gaze motor works around the shoulder joint as a supervisory authority, since the field of view and the target area the putter a motor, sensory-physiological Form unity. The development for the putt feeling is thereby much easier. By construction of the putter head is aimed at the golfer G and the putt process in a top view of the putter head a 90 angle to the horizontal suggests.

As another tool to aim at the finish line Z serve the attached on the top 15 of the putter head 1 Target marks 17.

The stability of the golfer in the standing position is by placing the forearm of the not needed Arm on the back improved since that arm then not separately balanced neurologically controlled must become. Concentrating on the only open one kinematic chain of the play arm or better the arm putter system with elimination of interference allows the golfer a precise putting process.

When the arm-putter system oscillates, it works G1 thumb thumb nail in extension of the system as hit area 11 of the putter head 1. The index finger G2 controls the pressure and thus the ball speed. The thumb, the index finger and the palm in collaboration with the visual, sensual and this is determined by neurophysiological inputs onset of movement moment, the pace and the target motor skills. As a result, high marksmanship with this putt method, in particular with an inventive one Putter reached.
