Description

Technical area:

The invention relates to a golf training device with which you can train several different movements.

State of the art

In golf, a variety of training devices is used. By way of example, in the United States of America design protected devices such as Des. No. 372,288, Des.397,754, US D446,276 S, or patent pending or patented apparatus such as the following: US 7,241,228 B2, US 7,261,640 B1, US 6,723,003 B1, US 2,025,519, US 2,150,580, US 2,169,407, US 2,457,351, US 4,384,718, US 5,246,234, US 5,350,177, US 5,464,220, US 5,527,037, US 5,599,240, US 5,893,805, US 6,106,408, US 5,984,801. However, such devices usually only allow one or a few movements to be practiced. On the other hand, those devices which allow the training of many different movements are generally complicated in structure and correspondingly expensive to manufacture and inconvenient to transport and / or use.

An object of the invention is therefore to provide a structurally simple and reasonably priced golf training device that allows the training of a variety of different movements. Other objects and advantages will be apparent from the following.

Presentation of the invention

The above object is achieved according to the invention by a device according to claim 1.

In particular, this is a golf training device which has at least a first, a second and a third member. The first member is connected via a first axis of rotation rotatably connected to the second member, and the second member is rotatably connected via a second axis of rotation with the third member. The second member has a mark comprising first and second members, wherein the distance between the first and second members is at least half the distance between the first and second axes of rotation. The distance of the first from the second element is divided by at least one further element of the marking in stretches of equal length. The first link has two types of markings. The first type of marking comprises a first and a second element, the distance of which is shared by at least 3 further elements of the marking in stretches of the same length. The second type of marking comprises a first and a second element, the distance of which is shared by at least one further element of the (second type) marking in stretches of the same length. The distance between two adjacent elements of this (second) type of marking is at least 7 cm, and the distance between the first and the second element is at least half the distance between the first axis of rotation and the farthest point from the first axis of rotation of the first link.

The presence of various types of markings extending over a substantial portion of the length of a link has advantages. This is particularly true when one type of marking has widely spaced, possibly colored, and therefore also well distinguishable elements from a distance. The advantages mentioned are described in detail below.

According to a preferred embodiment, the golf training device according to the invention is characterized in that it has three rotatably interconnected links, wherein on the first and the third member in each case at least two types of markings are provided with uniformly spaced elements, which markings in Extend longitudinally over at least two thirds of the length of the respective member. The said markings on the third member correspond to those on the first member. The first type of marking preferably represents a metric scale or an inch scale, and the second type of marking has colored elements, preferably different colors, at a distance of at least 10 cm. Angle scales are arranged on the first and on the second axis of rotation. In addition, the first and the third member are advantageously fixable to each other in a certain position and / or the device has means for attaching the first and third member to each other. It is preferred if at least the first and the third member on the top and on the bottom have markings.

Such a training device allows practicing various movements (see figure description) and thus improves the ability of the player and thus his chances of success in the competition when he plays without the inventive device.

The golf training device thus has at least three members, but it can also be provided 4, 5, 6 or more members. Particularly preferred are 3 to 6 and especially 3 members. The device as described in this document is preferably the device in the condition in which it is used for training.

The first member is rotatably connected to the second member via a first rotation axis, and the second member is rotatably connected to the third member via a second rotation axis. Preferably, the axes of rotation are arranged at right angles or substantially at right angles to the longitudinal axes of the links. However, deviations from the right angle of less than 10 °, preferably less than 5 ° and in particular less than 2 ° are possible. The axes of rotation are therefore preferably parallel, of course, deviations, as described, are possible. An arrangement of the axes of rotation allows the links to move in parallel (or substantially parallel) planes. Preferably, these are different levels. This allows the device to be folded without the individual links obstructing each other. According to a further preferred embodiment, the distance between the first and the second axis of rotation is constant and / or the distance of the points at which the axes of rotation intersect the second element (first / second pivot point) is constant.

The first member has at least two (distinguishable) types of markings. When referring to "species," it should preferably be understood that an average viewer (or at least a knowledgeable observer) is able to recognize that elements of the particular species belong together. Advantageously, the elements of a species for this purpose have more in common with each other and / or the more obvious similarities to elements of another type (e.g., black bars versus colored areas). Different types of markings are preferably those which have different advantages and / or functions and / or which can be used separately or are intended to be used separately.

The first type of marking of the first member comprises a first and a second element, the distance of which is shared by at least 3 further elements of the marking in stretches of equal (or substantially equal) length. At least 8, at least 13 or at least 23 further elements are preferred, with a preferred maximum number of elements of this type being 100, 60 or 40. This mark can be used as a relatively fine scale to adjust the position of the feet during training and / or to determine the distance of a golf ball from the hole or from another reference point (see figure description). According to a particularly preferred embodiment, the distance between two elements of this type is 0.5 cm or 1 cm or 1 inch or a multiple thereof (metric scale or inch scale), because this comparability with scales of other device is made possible and thus the Information exchange between players or the transition to the present training device easier. According to a preferred embodiment, the distance between said first and second elements (marking of the first type) is at least half as large and preferably at least 2/3 or 3/4 as large as the distance between the first axis of rotation and on the first member from the first axis of rotation furthest point of the first link. Preferably, the first type of marking extends over at least half (or at least 2/3 or 3/4, respectively) of the length of the first member.

When reference is made in this document, in the context of markings, to a "first element" and a "second element", it should preferably be understood to mean the first element and the last element of the marking in question, i. E. the most distant elements of the marking.

The elements may be, for example, dashes, dots, geometric shapes but also colored areas, etc. The distance between elements should preferably be understood to mean what would colloquially be referred to as distance. If the elements are extended elements (e.g., colored surfaces) and the above explanation is insufficient in one case, the distance between the elements may also be the distance between the elements. The midpoints are preferably to be defined as the centroids of the elements and / or as those points through which (for the respective element) most connecting lines run between vertices of the respective element. Markings or the elements of which they consist are preferably perceptible to the naked eye. However, it is also possible to use them e.g. (additionally) perceptible via the sense of touch. The markers or their elements preferably have a fixed position on the links. They are preferably used for orientation, positioning and / or orientation of the golfer and / or the golf ball. Preferably, the markers have a mere informational character. This information on the shape, function, etc. of the elements preferably also applies to the markers mentioned below.

The second type of marking of the first member comprises a first and a second element whose distance from at least one further element of the marking is divided into stretches of equal (or substantially equal) length. At least or exactly 2, 3, 4 or 5 further elements are preferred. The maximum number of elements should preferably be 15, 11 or 8. The minimum distance between any two elements of this type of marking is at least 7 cm, preferably at least 10 cm, more preferably at least 15 cm and in particular at least 20 cm. The distance between the first and the second element should be at least half as large and preferably at least 2/3 or 3/4 as large as the distance between the first axis of rotation and the farthest from the first axis of rotation point of the first member. Preferably, the second type of mark extends over at least half (or at least 2/3 or 3/4, respectively) of the length of the first link. The second type of marking thus has relatively widely spaced elements that occupy a substantial portion of the length of the first member. Thus, it can serve for orientation during the course of the movement, that is, when the user stands upright (see figure description). In contrast to elements located close to each other, the elements of said marking are also well distinguishable in terms of distance and concentration on the course of motion.

The minimum distance between two adjacent elements of the marker of the second type is preferably greater than the minimum distance between two adjacent elements of the marker of the first type and particularly preferably a multiple thereof. According to a preferred embodiment, the markings of the first (hereinafter "[1] mark") and the second type (hereinafter "[2] mark") are arranged parallel or substantially parallel to one another. This allows the elements of the [2] tag to quickly identify areas of the [1] tag without having to number the individual elements of the [1] tag. The [2] mark can also make the use of the device more efficient, because for certain tasks a fine scale like the [1] mark is not needed and therefore the user is not distracted from the multitude of elements of the [1] mark , The [1] mark and the [2] mark are preferably arranged next to one another. Preferably, they are juxtaposed side by side with respect to a connecting line between the first and second elements of the [1] mark and a connecting line between the first and second elements of the [2] mark. However, it can also be useful if the [1] mark and the [2] mark are provided in the same area. For example, the [2] mark of the [1] mark may be underlaid. The [2] -marking preferably has colored elements and more preferably different colored elements. By "different colors" is to be understood preferably that elements with different colors are present and / or that at least adjacent elements do not have the same color or color combination. These may, for example, be colored surfaces underlying the elements of the [1] mark or spaced-apart colored elements (eg dots) spaced from (and preferably parallel to) the elements of the [1] mark are.

Furthermore, it is preferred if the second and / or third member also has at least two distinguishable types of markings. The statements made above on the types of markings on the first link are hereby also disclosed in connection with the second and third links as preferred embodiments. However, since the second member is preferably shorter than the first member, reference should be made in addition to the below-mentioned information on the marks on the second member.

The mass of the members are preferably the following: First and / or third member: Length: 40-200 cm, preferably 50-160 cm, more preferably 60-120 cm and especially 70-90 cm Width: 1-20 cm, preferably 2-15 cm, more preferably 2.5-10 cm and especially 3-5 cm Thickness: 0.01-2 cm, preferably 0.05-1 cm, more preferably 0.1-0.7 cm and especially 0.3-0.5 cm Second member: Length: 25-120 cm, preferably 35-90 cm, more preferably 40-70 cm and especially 45-60 cm Width: 1-20 cm, preferably 2-15 cm, more preferably 2.5-10 cm and especially 3-5 cm Thickness: 0.01-2 cm, preferably 0.05-1 cm, more preferably 0.1-0.7 cm and especially 0.3-0.5 cm

For information in the form "x-y", the x-values are each also disclosed as independent minimum values and the y-values as independent maximum values.

The members are preferably made of one or more of the following materials: wood, metal (preferably aluminum), plastic (preferably polycarbonate). The material and / or a member made of the material (or materials) is preferably rigid. By "rigid" it is to be understood that such a member can not be unrolled or folded without damage and / or that such a member can be placed upright on a vertical wall, such that at most the lowest and uppermost 5% of the member in contact with the floor or the wall.

According to another preferred embodiment, the golf training device is characterized in that the third member has at least one mark corresponding to the first or the second type of marking of the first member. Said mark of the third member preferably has at least three elements. Although the device is placed on the ground in a U-shape, a ball can be positioned on the first and second links based on the markings (positioning on the corner of a rectangle defined by the first and second links). However, instead of imagining a rectangle, it is much easier and more precise to position a ball on an imaginary line between two points. Therefore, it is preferred if the first and the third member have corresponding markings. Preferably, these are markings of the second type. According to a particularly preferred embodiment, the third member has the same markings on at least one side as the first member. An associated advantage is that the device can be used equally well by right-handers and left-handers. Advantageously, the first, the second and the third member corresponding markings that define a grid in U-shaped arrangement of the links, which can be used to position the ball. These are also preferably markings of the second type.

The inventive golf training device is preferably characterized by the fact that at least one of the markers has different colored elements, wherein it is - as described above - is preferably a mark of the second type. Among other things, the second type of marking, with its elements far apart, is designed to be well perceivable even from a distance, e.g. To train movement sequences. This is made even easier by the use of colored elements. Elements that are labeled with numbers or letters, or that differ in their shape, can only be identified quickly enough by a user when viewed closely, and rarely when a head moves at the same time.

The second member has at least one mark, which comprises a first and a second element. The distance between the first and the second element is divided by at least one further element of the marking into stretches of equal (or substantially equal) length. The preferred minimum number of further elements is 3, 7 or 10, while the preferred maximum number of further elements is 50, 40 or 30.

The inventive golf training device is preferably characterized in that the second member, the distance between the first and the second element of the mark at least half as large and preferably at least 2/3 or 3/4 as large as the distance between the first and the second axis of rotation is. The marker should preferably extend over at least half the length of the second member.

It is also advantageous if the second member has at least two types of markings. The first type of marking preferably comprises a first and a second element as described above, the spacing of which is shared by at least 3, 7 or 10 further elements of the marking in stretches of the same length. More preferably, the distance between two elements is 0.5 cm or 1 cm or 1 inch or a multiple thereof (metric scale or inch scale). The second type of marking comprises a first and a second element whose spacing is shared by at least one and preferably at least 2 or 3 and preferably at most 15 or 10 or 5 further elements of the marking in stretches of equal length, the minimum distance between two elements this type of marking is at least 3 cm. The preferred minimum distance between two adjacent elements of the second type of marker is 3.5 cm or 4 cm. Since the marking of the second kind is preferably formed as adjoining differently colored areas in the second element, the distance is preferably to be understood as meaning the above-described distance between the center points of the elements. As will be described below, the second member is advantageously shorter than the other two members. This results in a smaller distance between the elements of the markers of the second kind. Unless otherwise described, the information on the markers of the first and second type in the first link but also apply to the second term.

Furthermore, it is preferred if at least a part, but preferably all markers (at least on one side, preferably both sides) of the second member symmetrically, in particular mirror-symmetrically, are configured. The points of a preferred mirror plane have the same (or substantially the same) distance from both points of intersection of the axes of rotation with the second element (first / second pivot point). Another preferred mirror plane passes through said intersections. This promotes ease of use for both right-handed and left-handed users. The device should preferably be designed to be symmetrical overall, in particular mirror-symmetrical, so that it can be used equally by right-handed and left-handed people. For this purpose, the first and third members are preferably also symmetrical with respect to the above-mentioned mirror axes by the second member. This concerns at least a part of the markings and preferably all marks (at least on one side, preferably on both).

It is advantageous if the inventive golf training device is characterized in that the distance between the first axis of rotation and the point of the first member farthest from the first axis of rotation is greater than the distance between the first and the second axis of rotation preferably at least 25%, 35% or 50%. It is preferred if the distance between the first axis of rotation and the farthest from the first axis of rotation point of the first member is at least 50, 60 or 70 cm. Preferred maximum values are 160, 120 and 90 cm. These statements made in relation to the first link (in comparison to the second link) preferably also apply to the third link (in comparison to the second link), in which case reference should be made to the second axis of rotation. The distance between the first and the second axis of rotation is at least 30.40 or 50 cm. Preferred maximum values are 90, 70, and 60 cm. If the distance to a rotation axis is mentioned, then preferably the distance to the corresponding intersection of the axis of rotation with the second member is meant. The shorter compared to the other members second member brings several advantages with it (see also figure description). If the axes of rotation are about shoulder-width apart (children approx. 30 cm, adults approx. 50 cm), for example, a very good circle section can be used to train the "Elevation of Swing Path". In a (reverse) Z-shaped arrangement of the members for training of "fade", "slice", "Draw" and "Hook" results due to the shorter second member is not too large distance between the parallel arranged first and third links, i. the first or third member is not too close to the feet or the ball.

Furthermore, it is advantageous if (reproducible) a certain angle between 5 and 85 ° between the second and the first or between the second and the third member is adjustable. The angle between the links should preferably be understood to mean the angle between their longitudinal axes and / or their edges. It is preferably an angle which can be predetermined by the device itself. For this purpose, means for setting a certain angle of 5 ° to 85 °, preferably from 10 ° to 30 °, more preferably from 15 ° to 25 ° and in particular from 18 to 22 ° are provided.

According to a preferred embodiment of the inventive golf training device, an angle scale / degree display is arranged on the first and / or second axis of rotation. Alternatively or additionally, the first (and / or third) and the second member in a certain position are fixable to each other, so that the certain angle, as described above, results.

The angle scale can be arranged for example directly on the link on the axis of rotation. The member connected at this point to said member (here: lower member) (here: upper member) then indicates e.g. a hole through which part of the angle scale (the set angle) is visible. Preferably also the upper member has an angular scale partially visible through a bore in the lower member. This allows the device to be used on both sides. In addition to this structurally simple but very versatile and therefore preferred embodiment, there are other ways to attach an angle scale. For example, the area at the axis of rotation at the upper member can be made transparent. Thereby, the angle scale becomes visible on the lower member, in which case in addition on the upper member e.g. a point or a bar can be placed, which indicates the set angle in coincidence with the angle scale (but makes it difficult to use the device on both sides). A combination of the above variants would be a transparent region in the upper limb, e.g. a hole filled with transparent material as described above. The transparent area makes only a part of the underlying angle scale visible, which makes bilateral use possible (transparent area in the lower limb, angle scale on the upper limb). An advantage over a bore is that no dirt can accumulate. Furthermore, it is possible to make the end of the upper member semicircular and attach the angle scale either on the upper member or on the lower member adjacent to the semicircular edge of the upper member. Accordingly, a reference point is provided here, by which the set angle can be determined. When the links are connected by a pin / screw and the pin is fixedly mounted with respect to the lower link, it is possible to marginally mount the reference mark on top of the pin and provide the angular scale on the upper link adjacent to the pin.

Advantageously, the device has means by which the first and the third member can be fixed relative to each other so that in the triangle of first, second and third member of the above-mentioned certain angle of 5 ° to 85 ° results and preferably at one of the two axes of rotation. The first and / or the third member may, for example, have one or more holes. These are preferably arranged so that the links form a triangle having as an angle the above-mentioned certain angle when the bores are made to coincide. It is particularly preferred if this results in an angle of 19-21 ° at the first or second axis of rotation. Then, a pin can be inserted through the holes, which can be used as a support for a guideway. If the device is placed upright on the ground, for example, two golf clubs arranged in parallel can be supported on the support and on the floor, thus providing a guideway for the ball. If the golf clubs are aligned along the limb which encloses the 19-21 ° angle with the second limb (which rests on the floor), the device may function as a so-called "stimping device" (developed by Edward Stimpson in 1937) take over the "Green Speed". According to an alternative embodiment, the support and / or the guideway may also be hingedly mounted on one of the members and preferably on the first or third member. However, the use of bore and pin is structurally simpler.

The golf training device according to the invention advantageously has means for attaching the golf training device to the ground and / or means for attaching the first and third members to each other. According to a preferred embodiment, these are bores and, in particular, those bores which are oriented parallel to the axes of rotation. These may e.g. interact with nails, pins or rods.

The first axis of rotation preferably intersects the first and / or second link in the last 20% or the last 10% of its length, and / or the second axis of rotation intersects the third and / or second link in the last 20% or the last 10th % of its length. In particular, it is advantageous if the first and / or third member projecting at right angles to the second member on one side not more than 10 cm, preferably not more than 5 cm, over the edge of the second member. The information preferably also applies to the second member, so that it does not protrude significantly or not substantially beyond the first or third member in the case of a right-angled arrangement of the apparatus. This facilitates the use of the device in an upright position (see description of the figures, in particular determination of the "green speed") and prevents protruding parts of the limbs from hindering training.

According to a preferred embodiment, the first, second and third member (preferably all members, if there are more than 3) have an upper side and a lower side, wherein the upper side and the lower side face each other in the direction of the axes of rotation. The top and / or bottom are preferably flat or substantially flat. At least one of the links, and preferably at least two of the links, have markings on both sides. Thus, the golf training device can be used on both sides and on the two sides different markings or different combinations of markings can be attached to facilitate the training of different movements.

The indications given above on the markings are preferably based on markings which are arranged on the same side. However, it may also be advantageous if the embodiments are applied to both sides of the device. This applies in particular to the presence of corresponding markings on the first and third links, which are preferably on one side to corresponding features of the first type. In addition, it is preferred if at least one type of markers is arranged on one side of the first and third member mirror-symmetrically with respect to the longitudinal axis of the respective member. This is advantageous if the device is to be used in a non-mirror-symmetrical arrangement of the links, for example in the Z-position or the inverted Z-position (see figure description). This allows a more versatile use and, among other things, the usability of the device by right and left-handers.

Examples

The invention is explained below by way of example with reference to the figures, which show a preferred embodiment.

Fig. 1 shows a top view of the top of the device in the U position, i. E. with right-angled links. The first and third members each have bores (111a, 111b) at their ends for fixing the device on the golf course or for fixing the first and third members together (the apparatus can then be used upright as a target, see FIG. 9). In addition, there are three markers in each case, namely an inch mark (elements of mark: 121a, 121b), a first 1/2 foot mark (elements of mark: 122a, 122b) in the form of arrowheads, and a second one /2-foot mark, the latter comprising different colored elements (131a, 131b). The inch mark, for example, allows the player to correctly position his feet for training the various movements. In addition, each of the first and third members has a green speed bore (112a, 112b) over which the two members, e.g. can be connected by means of a pin or bolt and so together with the second member form a triangle having an angle of about 20 ° at the second axis of rotation. When the device is positioned upright (resting on the second link, see Fig. 14) in this state, two golf clubs aligned in parallel can be positioned along the third link and resting on the post and the ground. Such an arrangement can perform the function of a Stimpmeters (the ball is placed on the golf clubs and then rolls at the correct angle to the ground). It is preferred if the holes (or other fixing means) are arranged so that the one member simultaneously marks the position at which the ball on the guideway (here: the golf clubs) must be placed. Finally, the first and third members still have information fields (141a, 141b). In this example, the information fields contain a sketch that identifies the different types of beats (strike identification). The second member also has a hole (111c) which serves to fix it to the ground or, with the aid of a rod, allows the device to be positioned upright in the manner of a football goal (use as a target with a larger target area than the variant mentioned above). On the edge there are two additional information fields (142, 143), which contain a Green Speed comparison table or the manufacturer's information. Two types of markings are provided on the second link. On the one hand, it is an inch mark (elements of the mark: 123). The second mark consists of colored areas (131c) which are underlaid by the inch mark and each span two elements (i.e., 2 inches) of the inch mark and extend to the edge of the second link. The colored elements on the three links (131a, 131b, 131c) define a position matrix or position grid, which the player can use to orient himself as the ball is positioned. At the same time, the parallel aligned first and third links define a target channel. The colored mark on the second link (131c) additionally serves to determine the "elevation of swing path" by observing which colored element the bat moves across.

The members have the following mass: First / third member: 800.1 mm × 38.1 mm × 4 mm; second link: 533.4 mm x 38.1 mm × 4 mm. They are connected by means of screws (screw size 4 mm × 15 mm) and nuts (nut size: 4 mm × 3 mm) and an intermediate layer (4.3 mm × 15 mm × 1.1 mm). The angular holes are 5-6 mm in diameter while the connecting holes are 4 mm and the Erddorn hole is 10 mm. However, as stated in the description, these masses can also be chosen differently.

1a, 1b, 1c and 1d each show a section of the device as shown in Fig. 1. This is the location at which the first is connected to the second (FIG. 1a, 1b) or the second to the third (FIG. 1c, 1d) link. Since the links are connected so that they can move in different parallel planes, complete collapse is possible, i. the first member is on one side and the third member is fixed on the other side of the second member. Similarly, an angular scale (144c) is mounted on the second member and partially visible through a bore (113b) in the first member. The connection takes place via connection bores (114b, 114d) which define a first axis of rotation. A second angular scale (144a) is mounted on the third member and partially visible through a bore (113c) in the second member. The connection in turn takes place via connecting bores (114a, 114c) which define a second axis of rotation (connection via screws).

Since the device is symmetrical in design to benefit both right-handed and left-handed users, the terms "first member" and "third member" are interchangeable herein.

Fig. 2 shows the underside and rear side of the device in plan view, wherein the members are in the reverse Z-position. The device has on the bottom z.T. other markings than on the top, making it possible to train more movements. In this position you can, for example, practice fade, slice and short game (Draw and Hook can be trained with a mirrored Z position not shown here). Also included on this side of the device are inch markers (elements: 221a to 222d) and 1/2 foot markers (elements: 222a to 222d) that can serve to position the feet and the ball. In addition, the first, second and third members each have a marking (here in the form of a line), wherein the marking (232) on the first member with "swing path", that (233) on the second with "target line" and those on the third (231) term are labeled "Line of Stance" and have a corresponding function. Analogous to the top or front of the device turn angle marks or degrees scales and holes are available, which allow the setting of angles also from the back of the device ago. This is shown in detail as a detail in FIGS. 2a, 2b, 2c and 2d (angle scale 144b (first link) and 144d (second link); bores 113d (second link) and 113a (third link)).

FIGS. 3 to 14 show different training variants. For clarity, the individual marks are not provided with reference numerals. Reference is made to FIGS. 1 and 2:

Fig. 3 Training variant "U" function: In this variant, the fine marking on the body closer limb allows a correct alignment of the feet ("Line of Stance / Address Position"). The colored dot marks (see Figures 131a, 131b) on the first and third links and the color marks (131c) on the second link define a position grid on which the ball can be aligned. The color mark (131c) on the second link also indicates the Elevation of Swing Path and the 1/8 Swing / Take Away. To do this, the user determines which color is obscured during transit. The first and third members specify a target channel.

FIG. 4 Training variant "Power Booster" function: The ball and foot position are determined analogously to the "U" function and a target channel is defined. Furthermore, the user can determine the "elevation of swing path" in the same way. The fact that the second member is now arranged on the other side makes it possible to define a "power mark" on the second member by means of the colored markings (131c). You can adjust the "Elevation of Swing Path" steeper or flatter, depending on which color marking (131c) the bat is guided during the swing. The second link is also a limit on which the player's attitude can be determined. Example: The golf club head reaches the ground closest point on the swing track when hitting the ball, and then moves further away from the ground during the swing. However, if a golfer attempts to swing the golf club head as close to the ground as possible after contact with the ball to approximately 4080 cm, so that it is guided only a few centimeters over the second limb and the sighted power mark arranged thereon the swing radius automatically increases as the player automatically tries to extend his arms as much as possible.

FIG. 5 Training Variant "Quarter Swingplane" Function: The position of the feet and of the ball (15) are determined here by means of the markings (123) on the second link, the second link additionally specifying a target line. The angle display allows the first and second links to be adjusted according to the desired Elevation of Swing Path. The device (11) is thus able to specify different "quarter swing plans" (it represents a two-dimensional projection of the "quarter swing plane"). The colored markings (131a, 131b) on the first and third limbs allow the movement during the stroke to be practiced in steps ("swing steps").

FIG. 6 Training variant "Bull" function: The second member has the same function in this variant as in the case of the "quarter swing plane" function. However, the "elevation of swingpath" can not be included in the training here. Instead, the "Bull" function can also define a "power mark" (see above for Fig. 4). The power mark is accordingly the area around the hole (111a or 111b, "Erddornbohrung") at the end of the first member.

Fig. 7 Training variant "Fade, Slice & Short Game" function: The arrangement of the device (11) in the form of an inverted "Z" allows the training of the types of blow "Fade", "Slice" and "Short Game" , The device (11) allows for correct positioning of the feet by means of the member closer to the body and the inch mark (221a) disposed thereon. A midline on the same limb, labeled "Line of Stance" (231), indicates to the user the function of that limb. The middle, i. the second link has a target line (233) as a marker, and the last link shows a centerline (232) titled "Swing Path" and inch markers for correct positioning of the ball (221d). Correctly setting the angles (e.g., 15 °) using the angle indicators (113a, 113d) on the pivot axes will automatically provide the correct alignment of the body with the target line. In addition, the "Elevation of Swing Path" can be adjusted by varying the angle. The larger the angle, the steeper the flywheel.

Fig. 8 Training variant "Draw & Hook" - Function: The arrangement in the form of a "Z" allows the practice of certain types of strokes analogous to the "Fade, Slice & Short Game" function described above. Here it is "Draw" and "Hook". Also, due to the arrangement of inch marks on both edges of the first and third links, one of the markers (221b) on the lower link is on the body-facing and one of the markers (221c) on the upper link on the ball zugwandten page.

FIG. 9 Training Variant "Delta" Function: The first and third members are fixed by means of a rod (mandrel, 19) inserted through bores (111a, 111b) at the end, thus resulting together with the second member and supported by the Staff an upright triangle. This serves the target exercise.

FIG. 10 Training variant "Half Moon" function (upright): Analogously to the "delta" function, the device (11) is positioned upright here by means of a rod (19). In contrast to FIG. 9, however, the bore (111c) disposed in the second link is used and the device (11) stands on the ends of the first and third links. These form due to their open position together with the second member a larger area target than in Fig. 9.

FIG. 11 Training variant "Half Moon" function (lying): In this variant, the device (11) is positioned in the shape of a crescent around the target (21) and thus forms a further target variant. The player can see from the position of the ball inside or outside the boundary formed by the device how successful he was ("Safe Put" distance). In addition, the markings on the links allow an estimate of the distance of the ball to the hole (use of that member which is approximately parallel to a line between ball (15) and hole (21)). Unlike prior art devices which surround the hole in the shape of a circle, the device according to the invention does not hinder the ball on its way to the hole (rolling) as it opens towards the player.

FIG. 12 Training variant "Half Moon Landing Zone" function (lying): Analogously to the variant shown in FIG. 11, but arranged somewhat further from the hole (21) and opened towards the hole, the device serves as a landing zone as another target variant. As the ball hops on impact, the device is generally not an obstacle and allows the ball to roll out due to its open position.

FIG. 13 Training variant "Putting Aid" function: In this variant, the first and second links are arranged in a line and the third link is arranged at right angles thereto. The colored markings (131c) on the second link allow the swing length to be determined during "putting", while the inch marks on the second and third links allow the feet to be correctly positioned (feet removed from each other and from the ball). Furthermore, the so-called "safe-put" distance can be determined, i. the distance at which the player is able to punch the ball into the hole. The lengths of the first and second links together form a distance range in which the «safe put» distance of a mediocre player lies (3.5 foot put).

Fig. 14 training variant "Green Speed Evaluation" - Function: Analogous to a so-called "Stimpmeter" allows the device (11) resting in an upright position on the second link to determine the "Green Speed". For this purpose, the first and third members are fixed by means of two bores (112a, 112b) and a rod (not shown) inserted through the bores. On the rod two golf clubs 13 (here: iron 3 & 4) are placed in parallel and at that member, which encloses an angle of about 20 ° with the second member, are aligned. A ball placed on the clubs then rolls at the correct angle in the direction of the lawn.
