Description

The invention relates to a golf training device, with a base part lying on the floor, which is directed towards the target hole and a guide bar attached to it via an intermediate element, also lying on the floor, on which a barrier in the form of a resilient bearing element can be tensioned Rod is attachable.

Such a golf training device is already known in the prior art (US Pat. No. 4,699,384 or EP 0 255 846 B1). In this known construction, the guide rod is designed as an arc segment, sleeves secured by screws being arranged both on the base part and on the guide rod. Although this device works satisfactorily, appropriate tools must always be available to bring the individual elements of this golf training device into the functional position. In addition, this known device mainly serves to improve the golf swing by having a spatially extending guideway which interacts with the club blade of a golf club.

Another prior art is a training device in which a spherical curve is mounted on a base part, on which the club blade of a golf club must be guided in order to perform the functional swing (US Pat. No. 2,807,472). This arrangement is very complicated and accordingly expensive. Other golf training devices use a frame-like frame (US Pat. No. 2,813,721), use light barriers (US Pat. No. 3,776,555), use marking rods (US Pat. No. 3,942,807, US Pat. No. 4,322,084) or use a cross element on which parallel displaceable rods are arranged (US -PS 4,023,811).

These known devices are either complex or complicated to handle.

In contrast, the object of the present invention is to design a golf training device of the type mentioned at the outset in such a way that there is an enlarged area of application with simpler usability.

This object is achieved in that the straight guide rod can be positioned at right angles to the base part via the intermediate element and that the bearing element has a region that can be connected to the rod, via which the bearing element can be locked on the guide rod at different angles to the base part. This results in the advantage of a simply constructed training device, which can be transferred from a collapsed, easily transportable state to the working position without additional tools, this working position making it possible due to the special design of the individual elements, a large number of functions to improve the functional posture to ensure the golfer. The golf training device according to the invention can be used from putting to wide tee.

In a further embodiment of the invention, the bearing element can be locked on the guide rod parallel and with at least one larger and at least one smaller angle to the base part. This results in a further area of application, in particular for improving the golf swing on the wide tee, in order to avoid so-called “slice” or “hook” tees from the outset.

In a further embodiment of the invention, the region of the bearing element which can be connected to the rod can be designed as a sleeve, the sleeve being connected via a profiled intermediate region to a bearing journal mounted in the bearing element is. Here, the bearing element can have a recess which can be penetrated by the profiled intermediate region and which is provided with detents for the various angular positions of the rod relative to the base part. The golfer only needs to adjust the intermediate area relative to the bearing element in order to ensure the desired position of the resilient rod that controls the wide swing.

With regard to the design of the bearing element, this results in a simple construction in that two areas encompass the guide rod and the bearing element on the side opposite the area has an elastic stop which can be acted upon by the bearing pin. Simply by rotating the sleeve, the bearing element can be securely fastened to the guide rod in the desired position.

In order to position the guide rod correctly at right angles to the base part in the working position, in a further embodiment of the invention the intermediate element can have a housing which comprises the base part and is provided with a cutout for the passage of the guide rod. This section can be equal to or greater than 90 °; If the cutout is larger than 90 °, an adjusting element is used on the corresponding boundary wall, with the help of which it is possible to achieve the 90 ° position of the guide rod very precisely.

To further facilitate this working position, the housing can have two locking lugs opposite one another, behind which the guide rod latches.

In order to assign further functions to the golf training device according to the invention, at least one longitudinally displaceable holding part can be arranged on the base part for mounting at least one orientation rod for the functional position of a golf player.

Preferably, two identically designed holding parts are used, which are provided with openings which run vertically and diagonally at the end for mounting an orientation rod. In this way, the correct ball positioning, the correct response and the avoidance of so-called "slice" shots can be achieved. Furthermore, with the aid of these orientation rods, it is possible for the golfer to take the correct swing level.

The base part and the guide rod can each be provided with markings in order to improve the orientation and for the exact setting of the individual elements in accordance with the size of the golfer.

There is also the possibility that the intermediate element and / or the bearing element and the end elements on the end faces of the base part and the guide rod are provided with marking arrows aligned with the target hole.

In addition, with regard to the golf training device according to the invention, the construction is simple in terms of cost, since the intermediate element, the bearing element and the holding parts each consist of plastic.

Different possible uses of the golf training device according to the invention.

According to FIG. 1, the golf training device according to the invention essentially consists of a base part 1 in the form of a rod directed towards the target hole, not shown, on the floor and a guide rod 2 fastened to it via an intermediate element 3 and also lying on the floor A tensionable bearing element 4 is arranged in the guide rod, in which a barrier in the form of a resilient rod 5 projecting obliquely upwards and delimiting the turn curve of a golf club can be attached.

From Fig. 1 it can be seen that the guide rod 2 is rectilinear and is positioned via the intermediate element 3 exactly at a right angle α to the base part 1 in its working position.

On the base part 1 there are two longitudinally displaceable holding parts 21 and 22, which are identical and each have an opening 40 and 41 vertically and obliquely on the end face. The end faces of the base part 1 and the guide rod 2 are each provided with a terminating element 55 or 55 '. Markings 50, 51 and 52 are arranged on the base part 1 and / or the guide rod 2.

From Fig. 1 it can also be seen that the intermediate element 3, the bearing element 4 and the end elements 55 and 55 'are each provided with a marking arrow 60, 61, 62, 63 directed towards the target hole.

2 shows the golf training device according to the invention in a folded form: As can be seen, the guide rod 2 in the intermediate element 3 is rotated in the direction of arrow I via the dashed position into the end position, in which it lies parallel to the base part 1. The end element 55 of the guide rod 2 has a recess and is accordingly supported on the base part 1. The bearing element 4 is in the relaxed position and is rotated by 180 ° with respect to the position according to FIG. 1. A sleeve 6 of the bearing element 4 receiving the rod 5 was rotated into a position in which it is also parallel to the base part 1. In this position, shown in FIG. 2, the golf training device according to the invention can thus be transported in a simple and space-saving manner.

3 shows the bearing element 4 in the working position analogous to the position according to FIG. 1: As can be seen, an area of the bearing element 4 that can be connected to the rod 5 is designed as a sleeve 6. This sleeve 6 is connected via a profiled intermediate region 7 to a bearing journal 8 which is mounted in the bearing element 4 and which is rotatably mounted in the bearing element 4.

The bearing element 4 has a recess 9, which is penetrated by the profiled intermediate region 7. This recess 9 extends approximately 90 °. 4 and 5, it is provided with detents 10, 10 'and 10 ", respectively.

These detents cooperate with the profiled intermediate region 7: the marking 10 holds the rod 5 exactly at right angles to the guide rod 2 according to FIG. 1 via the profiled intermediate element 7 and the sleeve 6; accordingly, this rod 5 lies exactly parallel to the base part 1.

The marking 10 'defines an angle greater than 90 ° with respect to the rod 5, the marking 10' 'defines an angle less than 90 ° with respect to the rod 5. This makes it possible to position this rod 5 exactly according to the desired course of the swing of a golf club (see Fig. 8g and h).

4 further shows that the bearing element 4 encompasses the guide rod 2 over two areas 11 and 12 and has an elastic stop 13 which can be acted upon by the bearing pin 8 on the side opposite the areas 11 and 12. The bearing element 4 and the bearing pin 8 are preferably made of plastic; the elastic stop 13 made of rubber.

The bearing pin 8 is designed such that it is provided on the side opposite the profiled intermediate region 7 with an eccentric zone 14 for acting on the elastic stop 13. 3 and 4, this elastic stop 13 has a corresponding guide curve 33.

4 and 5, the sleeve 6 with the intermediate element 7 is in the rest position. Here, the bearing journal 8 does not act on the elastic stop 13 or the guide curve 33 with its outer circumference.

If the sleeve 6 with the profiled intermediate region 7 is turned clockwise according to arrow II into the position according to FIG. 3, the eccentric zone 14 of the bearing journal 8 acts on the corresponding curve 33 of the elastic stop 13, whereby this is pressed against the guide rod 2 . Since that Bearing element is fastened to the rod 2 via the two regions 11 and 12, in the position according to FIG. 3 via the eccentric zone 14 and the elastic stop 13 there is a perfect and secure mounting of the bearing element 4 on the guide rod 2.

There are therefore no tools required to move the bearing element 4 from its rest position according to FIGS. 4 and 5 into the working position according to FIG. 3. In this position, the rod 5 can be inserted into an opening 26 of the sleeve 6, which lies exactly parallel to the base part 1 when the profiled intermediate region 7 interacts with the locking device 10, 10 ′, 10 ″.

The bearing element 4 has a stop 27 in the upper region with respect to the recess 9, so that the sleeve 6 with the profiled intermediate element 7 and thus the rod 5 can only be pivoted out to this region.

6 and 7 show the intermediate element 3, which connects the base part 1 to the guide rod 2. As can be seen, this intermediate element 3 has a housing 15 which surrounds the base part and which is provided with a cutout 16 for the passage of the guide rod 2. This cutout 16 is equal to or greater than 90 °, a boundary wall 17 running parallel to the base part 1. This boundary wall 17 is used to rest the guide rod 2 in the folded position according to FIG. 2.

Furthermore, the cutout 16 is delimited by another boundary wall 18, which can lie exactly 90 ° to the boundary wall 17. Alternatively, there is the possibility that this boundary wall 18 has a larger angle than 90 ° to the boundary wall 17 and an adjusting element 19 is inserted into this boundary wall 18. This adjustment element 19 makes it possible to use the golf training device according to the invention Type exactly to cause the rectangular position of the guide rod 2 to the base part 1.

From Fig. 7 it can be seen that the housing 15 of the intermediate element 3 in the 90 ° position of the guide rod 2 has two opposing locking lugs 20 and 20 '. Therefore, if the guide rod 2 in the intermediate element 3 is rotated into the position according to FIG. 1, both locking lugs 20 and 20 'snap behind the guide rod 2 and hold it exactly in the 90 ° position with respect to the base part 1. In this area there is also the wall of the cutout 16 rounded to act on the circumference of the guide rods 2.

The guide rod 2 is mounted in a bearing journal 25 which is rotatably arranged within the housing 15 of the intermediate element 3. The intermediate element 3 and the bearing pin 25 are made of plastic, so they are easy and inexpensive to manufacture.

As stated at the beginning, with the aid of the golf training device according to the invention, it is possible to ensure a number of training options for the golf player: FIGS. 8a to i show different possible uses of the device according to the invention.

Fig. 8a shows the basic position, i.e. So-called "Basic Alignment": The base part 1 points with its markings 55 to the target hole, the guide rod 2 is at right angles to it. The resilient rod 5 is also fastened to the guide rod 2 via the bearing element 4 and also on the floor and points to the target position. Since the rod 5 and the base part 1 point towards the target hole, the golfer can now take the exact position.

8b shows the functionally correct ball position: the base part 1 and the guide rod 2 with the resilient rod 5 are located itself in the position according to FIG. 8a. An orientation rod 30 is inserted into the holding part 22 and points exactly to the golf ball 35. The golfer can now take the correct position with respect to the orientation rod 30, which on the one hand is correctly aligned with the target hole and on the other hand is adjusted to the exact ball position. This ensures perfect ball positioning. It gives the player a precise idea of where the ball 35 should be in the correct response position.

8c shows the so-called "right knee restriction": the base part 1 and the guide rod 2 and the rod 5 are in the starting position according to FIG. 8a. An orientation rod 31 is now protruding obliquely through the opening 40 into the holding part 22 and inserted into the ground. This rod 31 thus assumes the position shown in FIG. 8e.

If the golfer now stands so close to the orientation bar 31 that his knee touches this bar, there is an intensive contact, which is further intensified if the golfer makes a wrong swiveling movement when swinging back.

The golfer stands so close to the obliquely rising orientation rod 31 that his knees and hips touch it during a wrong swiveling movement in the back swing. The sensor contact that arises is advantageously so intense that a fault is eliminated after a short period of time.

8d shows the position of the so-called "Eliminate Sliding": Here an orientation rod 32 is used, which is pushed to the left of the player through the opening 40 of the holding part 22 and inserted into the ground. This orientation rod 32 thus assumes the identical position according to FIG. 8e.

For a modern and very efficient golf swing, it is necessary for the player to keep his in the starting position, i.e. Responsiveness vertical axis taken does not leave too far to the side, neither in backswing nor in backswing. This error can be eliminated very quickly and sustainably by positioning the orientation rod 32 close to the body on the side of the body facing the target. If the golfer moves his hip or knee too much to the target during the tee-off, they touch the orientation rod 32. Again there is a tactile contact which clearly indicates this misconduct to the player.

FIG. 8f shows a combination of the arrangements according to FIGS. 8c and d: As can be seen, an orientation rod 31 and 32 is stretched into the holding parts 21 and 22 and protrudes obliquely from the floor analogously to the arrangement according to FIG. 8e. The player is now between these two orientation bars 31 and 32 and immediately notices if there are errors on the tee (in whatever phase).

In the position according to FIGS. 8g and 8h, the rod 5 lies at an angle β to the guide rod 2 or to the floor. The golf ball 35 is placed under this inclined rod and an attempt is made to hit it with normal swing. If the player now comes to the ball with his golf club from outside the finish line, he first hits the resilient rod 5. This meeting is not only felt but also acoustically perceived. This enables the player to easily avoid this mistake the next time they hit.

While Fig. 8f deals with the importance of the correct swing level and Fig. 8g and h correct a wrong shot by the player via the spring rod 5, Fig. 8i shows the possibility of using the golf training device according to the invention also when putting: Here is about the bearing element 4 and the sleeve 6 the resilient rod 5 tight and parallel to the base part 1 pushed. The width B should be such that for very short putts the golf club is swung straight back and straight forward.

The width B corresponds approximately to the putter head width, which means that a short putt can be carried out very correctly as a result of the resilient rod 5 and the base part 1. If the putter head 38 leaves the straight ideal line, it either meets the base part 1 or the resilient rod 5 on the left or right.

For longer putts you raise the rod 5 a little. Then you put the golf ball 35 under the rod and putt. Any deviation from an even, weak putt curve is immediately detected by the golfer's eyes. This creates a reliable feeling of how good or bad the movement is when putting.

In addition to the positions shown in Fig. 8a to i, there is also the possibility of correction with regard to "low hands": At least one of the orientation rods 31 and 32 is in an inclined position, in such a way that the end in the response position is just above the Hands of the golfer. It is now important that the hands of the golfer do not touch this rod during the swing.

The two holding parts 21 and 22 not only serve to hold orientation bars 31 and 32 in different positions, but can also have continuous recesses 23 and 23 '. These recesses 23 and 23 'serve to securely hold the orientation bars 31 and 32 parallel to the base part 1 in the transport position according to FIG. 2. The entire golf training device can thus be transported in a functionally reliable manner when folded.

The golf training device according to the invention is simple in construction, easy to transport and designed to be very cost-effective. It leaves move easily from rest to work position without any aids and makes it easy to correct errors in a large number of golf strokes, from the short putt to the long tee.
