Description

Putters, in particular for training purposes

The invention relates to a putter, in particular for practice purposes, with a shaft and a club head which has a striking surface.

When playing golf, an attempt is made to hit the ball from the tees with as few strokes as possible

Play hole. To do this, you use a series of rackets that meet the respective stroke requirements. The last strokes before the so-called punching usually take place from the green. Where the ball is more or less close to the hole. To bridge this short distance, the so-called putter is used, the design of which differs from that of the other golf clubs and which also requires a different striking technique than that of other clubs. Ideally, the starting direction of the ball in the putter is as straight as possible direct extension to the swing line. To ensure this, several impact torque factors must be met. The straight putt movement, the face position at the moment of impact, the vertical angle of arrival and the center of the encounter with the face form the essential basis for a successful putt.

Exercise devices or putters for exercise purposes for such impact moment factors are already known. For example, on a practice green on a fixed guide rail, the straight putting movement can be practiced by guiding the putter as close to the guide rail as possible when striking. The disadvantage of this exercise is that only the straight putting movement is trained and, due to the guide rail, only the same hole can be played.

Also known is a practice putter with a club head with a club face that extends over the club head width and two non-adjustable guide arms that protrude beyond the club head sides. Since the ball must only be in the ball corridor formed by the guide bracket protruding beyond the sides of the club head in order to be able to hit the ball with the club face, the ball does not differ significantly from the one like it with a putter common in golf. Only a strong deviation from the ideal putt line by touching the ball on the guide bracket is apparently perceived, which of course cannot be sufficient for extensive putt training. A golf club, namely putter, has become known from DE 295 17 016 U, in which the putter head has at least one closable recess for receiving weight elements. Apart from the fact that this putter is not intended exclusively for exercise purposes, the hardness of the stroke can be regulated by interchangeable weights and thus adapted to different play systems, but this only includes the task of the present invention to a lesser extent.

The invention has for its object to provide a putter, in particular for training purposes, of the type described at the outset, with which it is possible to create the essential basis for a successful putt hit moment factor, such as the straight putt movement, the face position in the hit moment, the vertical Practice the angle of arrival and the center of the meeting.

This object is achieved by the characterizing features of the claims.

A striking plate assigned to the striking side preferably has a striking surface which is arranged on a raised area consisting of four deflecting surfaces and whose width is kept narrow in comparison to the width of the club head, which is important for the center of the meeting insofar as the ball is hit in the center of gravity of the putter. The vertically oriented width of the face is preferably about 5 mm, but can also be adapted to other needs.

For professionals, this face can be round, for normal players, a rectangular shape is preferred, because if the longer sides of the rectangle are arranged horizontally, more Meeting space is available. If the user is more experienced then, the rectangular striking surface can be placed vertically, thus reducing the impact area.

A round or smaller meeting area trains the moment of impact and allows even better training of horizontal and vertical sweet spots.

The striking plate can not only be assigned to a commercial club head of a putter or a special club head of a practice putter, but also, for example, to a corresponding attachment on a commercial putter or practice putter.

In cooperation with the striking plate, but independently of this, guide sticks can be assigned to the club head, the ends of which form an opening for the passage of the ball. This opening can be changed by the guide bracket by means of a grid and can be tuned to the respective playing strength during practice. It is also conceivable for these guide brackets to be plugged onto a commercially available putter, for example on its back, by means of a corresponding holding device.

If a hit is successfully executed, the ball passes through the opening and the ball corridor formed by the guide brackets and, after impacting the striking surface hit in the middle, reverses the ball corridor through the opening in the extension of the swing line. If, on the other hand, the ball does not hit the exact center of the striking surface, i.e. if the ball strikes one of the longitudinal edges of the striking surface or a deflecting surface adjacent to the longitudinal edges of the striking surface, it is deflected by the impulse component occurring transversely to the swing line and gets caught in the Ball corridor, which immediately indicates the failure of the stroke.

Another striking plate of the same design is preferably located on the rear of the club. It differs from that on the face only by the roughly twice the width of the face. Both striking plates are interchangeable, so that different sized striking surfaces are available. Since the opening for the ball passage can be adjusted as desired as well as the size of the face, the putter can be individually adjusted for practicing a straight putt movement and for the center of the hit to any skill level.

For the rest, some experienced players use the striking plate with ball corridor to hit it, but then the second striking plate on the back of the club head.

Another impact torque factor is the vertical angle of arrival, with which the ball is hit exactly at the apex of the arch if the swing is carried out correctly in accordance with the other impact torque factors. By turning the striking plate by 90 °, the width of the striking surface lies transversely to the putter and thus deliberately offers the ball little striking surface vertically, so that this ideal meeting point (sweet spot) is only hit if the swings take place at the ideal height of the putter to the practice green. If the ball is hit below or above the apex, ie if it hits one of the longitudinal edges of the striking surface or one of its adjacent deflecting surfaces, the ball "jumps" or behaves similarly to the vertical position of the striking surface, which in any case immediately indicates the failure of the blow. The alignment of the face position in the moment of impact to the target or putt line is sustainably supported by two direction marks, which are aligned at different heights on the top of the club head directly behind the shaft. Since the direction marks are at different heights, they can only be brought together with the target or putt line on a common direction line if the player's eyes are in a normal putting position perpendicular to the direction marks, which is advantageous for a straight putt movement anyway.

Due to optical problems, the correct alignment of the putter to the finish line is still difficult, which is also the cause of frequent mistakes during putting. A remedy for this source of error is often seen in drawing a line on the ball using a template, aligning the ball with the help of this marking on the hole and placing the striking face of the putter perpendicular to the ball marking. This method is further improved with an aiming arm according to the invention. The target gap of the aiming bar, which is detachably mounted on the club head, is brought into alignment with the marking above the ball in a simple manner, while the putter sits on the practice green. Because the target gap is aligned with the longitudinal axis of the club head, the putter is inevitably correctly aligned, which also results in the optimal ball position between the guide arms.

A rubber rope, which is stretched between the club head and a ground anchor after the hole, can also be used for improved aiming. The rope must then run exactly over the ball. The rope can be easily inserted into the Aiming stirrups can be attached or attached to this putter by means of a clamping device on the shaft or on the shaft extension for practice purposes or also to any play putter customary and available on the market.

In a preferred embodiment, a releasable holder is provided for fixing the rubber rope to the shaft. This detachable holder consists essentially of a strip and a tension lever. The strip is preferably variable in length and / or flexible. In the position of use, the strip wraps around the putter shaft, the tensioning lever being able to be tilted relative to the strip, so that it is supported firmly against the shaft. This stretches the strip and fixes it to the shaft itself.

For better guidance of the tensioning lever relative to the shaft, an end face of the tensioning lever, which strikes the shaft, is designed as a notch surface.

In the tensioned position, the tensioning lever is in an approximately horizontal position so that it can serve to hold the rubber cord. For this purpose, a holding needle can preferably be inserted into the tensioning lever, on which the rubber cable is fixed.

In order to take into account a different sweetspot of the putter, the clamping lever has several holes so that the holding needle can be adjusted exactly above the sweetspot.

The main advantage of such a target device is that the player does not have to follow the putter with the eye, but rather can keep his eye on the ball. The rubber rope must lie exactly above the ball's point of impact. The rubber cord itself is highly elastic, so that it does not oppose the putter swinging. The player hardly notices them.

Even after hitting the ball, the player can follow whether his playing surface is still perpendicular to the line. In this way, he not only controls his stroke before hitting the ball but also afterwards.

It is also conceivable to stretch a rubber rope between two ground anchors, one after the hole, the other after the ball. The aiming arm can then be replaced by a vertically positioned bracket with a recess in which the rope runs when it hits.

By simply loosening and screwing down the two striking plates, the shaft inclination angle can be changed in between by rotating a shaft holding plate with the shaft as required by the user. The putter can be used by right- and left-handers alike by unscrewing the striking plate mounted on the striking side, pulling off the adjacent shaft-holding plate together with the shaft from the grub screw, turning it back on the grub screw rotated by 180 ° and positioning it positively using the striking plate screwed on again.

Different shaft lengths can be easily adapted to different body sizes and arm lengths by exchanging the shaft including the shaft holding plate.

With a damping plate that can be used in materials of different weights, the practice putter can be easily adapted to the usual putter in its impact hardness. Of course, any hole can be played on the practice green with the present invention, which seems essential for comprehensive training success. At the same time, this variable putter can be used to train the feeling for stroke metering and practice reading the green.

An embodiment of the invention is shown in the drawings and will be described in more detail below. Further embodiments result from the subclaims and the description. Show in the drawings

Fig. 14 is a plan view of an earth mandrel.

As shown in Fig. 1, a club head 4 in the putter head on its face 21 has a circular striking plate 1, the outer surface of which has a knurl 13 to which a conical elevation 14 connects, which is divided by two opposing deflecting surfaces 14 and which in a rectangular flat face 15 opens.

Two markings (not shown in more detail) can be provided on the face 21, which are marked with e.g. Notches 42 or other markings (see Figure 2) interact. They ensure that a face 15 mentioned later is set horizontally or vertically.

Starting from the rear of the club head 23, the club head 4 is comprised of right and left guide brackets 5, 6, which extend beyond side walls 19 of the club head 4. At their respective front ends 17 they are bent inwards at right angles and form an opening 18 for the ball passage, to which a ball corridor 36 lying between the guide brackets 5, 6 is connected. A sectional image (FIG. 4) shows a further striking plate 8 of the same design, the striking surface 15 of which differs only in a width 22.1 from a width 22 of the striking plate 1 (FIGS. 2 and 3).

On a threaded pin 7 passing through the club head 4 on a longitudinal axis 20, the striking plates 1, 8 are optionally provided for screwing on at both ends thereof. For this purpose, both striking plates have threaded bores 12. The club head 4 contains a bearing hole arranged centrally on the longitudinal axis 20, running below a prism 33, for receiving a shaft holding plate 2 and a damping plate 3, both of which are likewise arranged on the threaded pin 7. The directly attached to the striking plate 21 attached to the striking plate 1 shaft holder plate 2 serves to hold a firmly connected shaft 10 and to adjust the shaft inclination angle as required transversely to the longitudinal axis 20. Above the shaft holding plate 2, a bearing hole is open as far as the shaft 10 for the Need pivoting movement to adjust a shaft inclination angle.

Some players use only the shaft holding plate 2 with two striking plates 1 and 8 arranged on the grub screw to practice a uniform swing. With an uneven swing, the grub screw 7 moves in the shaft holding plate, so that when striking plate 1 or 8 strikes the shank holding plate 2 there is a crackling sound.

The damping plate 3 adjoining the shaft holding plate 2 on the threaded pin 7 is supported in Direction of the back of the club head 23 on the rear wall of the bearing bore.

The prism 33 protruding above the damping plate 3 over the top of the club head 4 has on it

Comb surface has a vertical milling for receiving an upper direction mark 9

Metal plate, preferably made of aluminum. A print can also be used instead of a milled and metal plate.

The prism 33 sits on a base body 35, preferably made of plastic, in which the damping plate 3 and the shaft holding plate 2 are also received.

Below the upper directional mark 9, starting from the top of the club head 4, there is a vertically recessed V-shaped recess 37 which merges into a horizontally arranged groove for receiving a metal plate, preferably made of aluminum, also formed as a directional mark 11. Instead of this, an imprint could also be used here. Furthermore, a direct inspection of the threaded pin 7 can also be possible, so that it serves as a marking. The upper direction mark 9 and the lower direction mark 11 are aligned with the longitudinal axis 20.

On the back of the club head 23, the end parts of the right and left guide brackets 5, 6, as shown only in FIG. 5, can be between an upper and a lower bottom edge 24.1 and 24.2, being pressed against the back of the club head 23 by an optionally screwed on impact plate 1, 8 and are fixed. The degree of their adjustment and thus the determination of the width of the opening 18 for the ball passage takes place by means of a selectable position of a grid 32, which consists of spaced grooves 29 machined into a support surface 31 of the guide bracket 5, 6 and two grid bolts 30 which can be engaged in the grooves 29, which are arranged at the appropriate distance on the bottom edge 24.1 of the club head 4. By loosening the striking plate 1, 8, the fixing of the guide bracket 5, 6 is canceled so far that it is raised and a new setting of the grid 32 can be selected by a horizontal displacement.

The cutouts 34 on the end parts of the guide bracket 5, 6 prevent the limitation to the closest possible adjustment of the grid 32 when the guide bracket 5, 6 approaches the threaded pin 7.

In order to keep the guide bracket 5, 6 stable during the striking process, a guide pin 25 emerging from the wall of the guide bracket 5, 6 engages in a guide groove 26 located in the racket head 4, which extends horizontally starting from the rear of the club head 23. A 0-ring 27 seated on the guide pin 25 in the region of the guide groove 26 additionally acts to dampen vibrations (FIG. 6). The slight tapering of a sliding surface 28 of the guide bracket 5, 6 towards the end 17 facilitates the swinging of the putter without touching the practice green.

In a further embodiment, a target bracket 38 is arranged on the top of the club head 16, the target gap 39 projecting into the ball corridor 36 is aligned with the longitudinal edge 20. The aiming arm 38, which is preferably formed from steel wire, opens in the region of the Striking plate 1, 8, where its two legs 40 are anchored at an obtuse angle between the shaft 10 and the side walls 19 and are removably anchored (FIG. 7). The height of the aiming arm 38 projecting from the club head 4 is dimensioned such that there is a distance of at least 10 mm between the aiming gap 39 and a conventional golf ball located underneath (FIG. 8).

The embodiments and the nature of the invention are not restricted to the present exemplary embodiments. The material of the club head 4 can also consist of metal or plastic, such as the guide bracket 5, 6, the striking plates 1, 8 or the aiming bracket.

The operation of the present invention is as follows:

The putter according to the invention is an exercise device with which the three most important impact moment factors can be trained in one movement, namely

- the meeting of the sweet spot,

- a straight face position and

- a correct swing path.

A successful putt depends on these factors. In addition, reading the green and dosing must be trained. The putter according to the invention is a variable putt training device that can be adjusted in several details to the desired needs. It can be used by right- or left-handers, the shaft inclination angle (Lie) can be adjusted and the weight can be changed. The biggest advantage of the Putters according to the invention compared to other training means, however, are that, like the actual putter, it can be used to train on the putting green.

A first important point is the direction of swing along the finish line. The ideal putt movement is a straight pendulum movement along the finish line. If the guide brackets 5, 6 are adjusted, ball corridors 36 of different widths are obtained. If the club path deviates from the ideal line, the ball will get caught in the putter between the guide brackets 5, 6 when swinging back or forward.

The striking surface 15 should be oriented perpendicular to the target line at all times. Only with longer putts can the face open slightly at the end of the backswing. Should the striking surface 15 twist, the front opening 10 of the putter according to the invention narrows, and the ball will not reach the striking surface 15 or get caught in the ball corridor 36 after the hit.

If the ball is hit with a normal putter outside of the sweet spot, the face turns and the putt usually remains too short. The putter according to the invention trains the hitting of the sweet spot through its narrow face 15. Even with small deviations, the ball hits one of the inclined surfaces 14 to the left or right of the striking surface 15 and gets caught in the ball corridor 36.

The vertical hit of the sweet spot can be trained if the narrowest face (5 mm) is turned by 90 °. The club face is now in a horizontal position. If the ball is hit too high or too low, it will bounce extremely for the first few centimeters. Aligning the putter correctly is difficult - even for top amateurs and professionals. With the snap-on Y-shaped aiming device of the putter according to the invention, aiming is considerably simplified. It is sufficient to draw an equator line on the ball using a template (available from specialist retailers). This line should be aligned with the goal. The user places the putter according to the invention behind the ball in such a way that the aiming device coincides with the line on the ball. When the eyes are above the ball, the aiming device and the equator line can be seen one above the other. The rear sight and the grain, which are attached to the right at the end of the club head, are visually one above the other.

All putts that find their way out of the putter start exactly in the desired direction. Better feedback on reading is also achieved here. If you putter with a normal putter, you do not know whether the ball started in the intended direction and therefore cannot draw any conclusions about the quality of the reading. The same applies to dosing. Since the ball was hit with the sweet spot when it left the putter according to the invention, there is an unadulterated feedback about the strength of the stroke. If the ball stays too short, the stroke was not firm enough. When putting with a normal putter, the dosing may have been incorrect if the putt was left too short or the sweet spot was simply missed. Of course, you can't improve with inaccurate feedback.

An investigation has shown that almost all golfers use the

Underestimate break while reading. They then no longer fully trust their assessment of the ball and swing intuitively in a direction further above the hole. In this way it becomes difficult to learn a movement without compensation. The putter according to the invention no longer allows this, since it immediately punishes any tilting. The putter according to the invention therefore forces the user to aim correctly, because a technique in which wrong reading and aligning compensates with a wrong stroke is not possible with him.

In order to adjust the practice putter to the weights of your own putter, weight inserts are included. Therefore, the damping plate 3 can be made of different materials and can be replaced.

FIG. 9 also shows a target device according to the invention. This consists essentially of a rubber rope 43 or the like. Expandable element, which is fixed on the one hand via a clip 44 on the shaft 10 of the putter and on the other hand on a ground anchor 45. In the position of use, this rope 43 spans a ball 46, for example, a marking as a line is also applied to this ball 46. When hitting the rope 43 must match this marking on the ball 46. In this way, a hole 47 can be sighted very cheaply.

11 to 13, a bracket 50 can be provided for fixing the rubber rope 43 to a shaft 10 of the putter. The holder 50 consists essentially of a strip 51 and a tensioning lever 52, the tensioning lever 52 being connected to the strip 51 via lateral rivets 53.1 and 53.2. The rivets 53.1 and 53.2 pass through corresponding holes 54 in the strip 51. Since a plurality of holes 54 are provided on the strip 51, the strip 51 can loop around shafts 10 with different diameters. To fix the holder 50, it is in a position of use, as shown in FIG. 12. The strip 51 is wrapped around the shaft 10 and the rivet 53.1 is pressed through the corresponding hole 54.

After a desired height of the holder 50 on the shaft 10 has been determined, the tensioning lever 52 is pivoted through 90 ° into the position of use shown in FIG. 13. A notch surface 55 of the tensioning lever 52 presses against the shaft 10, so that the strip 51 is put under considerable tension. As a result, the holder 50 is fixed on the shaft 10 in a relatively rotationally secure manner.

A holding needle 57, which forms a loop 58 at its free end, is now preferably inserted over the sweetspot of the putter in the tensioning lever 52 or corresponding bores 56. This loop 58 is used to fix the rubber rope, which of course can also be knotted.

14, an earth mandrel 60 is shown as the ground anchor. In addition to a mandrel 61 and a writable surface 62, it has a winding section 63 for winding the rubber rope. Undercut notches 64.1 and 64.2 are assigned to the winding section 63 at the edges.

A head section 65 has small incisions 66 in which the rubber cable and in particular the end of the rubber cable can be clamped.

Another possibility for aiming is indicated in FIG. 10. Here is a bow-shaped on the club head

Aimed at element 48, which forms a trough 49. The rope 43 runs here between one Ground anchor 45 and, for example, a further ground anchor after the ball 46, the cable 43 running over the marking of the ball 46 mentioned above.

When striking, the club head 4 is moved back and forth between the ball 46 and the latter ground anchor, the cable 43 running in the depression 49.
