Definitions
- the invention relates to a golf training device.
- the present invention relates to a golf training device comprising a visual guide comprising a tee receiving section for receiving a golf tee and two elongated, deformable elements each having first and second ends, wherein the two elongated elements are connected to the tee receiving section at their first ends.
- the golf training device further comprises two tactile markers connected to the two elongated, deformable elements, respectively, at or proximate to the second ends.
- each of the elongated elements has a length of 10 to 100 cm, more preferably 20 to 75 cm, and even more preferably 30 to 50 cm.
- each of the elongated elements has a width of 1 to 10 cm, more preferably 2 to 8 cm, and even more preferably 5 to 6 cm.
- each of the elongated elements has a thickness of 0.5 to 10 mm, more preferably 1 to 8 mm, and even more preferably 2 to 6 mm.
- the term “connected” encompasses both a connection via any detachable connecting means (such as a snap fastener or a hook and loop fastener) and a permanent, inseparable connection, i.e. where parts being connected are formed into one single piece.
- the two elongated, deformable elements may be two separate strips which can be detachably connected to the tee receiving section by suitable connecting means.
- the two elongated, deformable elements may be permanently connected to the tee receiving section.
- the elongated elements and the tee receiving section may together form one integral, unitary piece and may even be integrally made from a single piece of raw material, the unitary piece having, e.g., the shape of a V or U.
- the term “deformable” indicates that the elements referred to are capable of being manually reshaped (e.g. folded, bent, curved or rolled) during the normal course of deploying and restoring the golf training device. This improves the above-mentioned functionality of providing guidance during the swing. Due to its defonnability, the user may adapt the shape of the deployed device to his/her personal needs. For example, a certain curvature of the swing to be performed may be indicated by a correspondingly bent elongated element of the visual guide. For this purpose, it is preferred that the deformable elements are deformable within a plane spanned by the deformable elements and the tee receiving section, i.e.
- the deformability of the elongated elements also allows for reducing the size of the golf trainer in order to carry it easily in a golf bag without it taking up much space or adding any significant weight. It is thus preferred that the elongated elements (and preferably the entire visual guide) can be folded, bent, curved or rolled. It is further preferred that the entire golf training device can be reduced to a three-dimensional shape with its largest extension (corresponding to its length) being smaller than 30 cm, preferably smaller than 25 cm, more preferably smaller than 20 cm.
- the width and/or height of said three- dimensional shape is smaller than 15 cm, preferably smaller than 10 cm, more preferably smaller than 8 cm.
- the weight of the entire golf training device is preferably smaller than 300 g, more preferably smaller than 200 g and most preferably smaller than 150 g.
- the elongation at break is greater than 20%, more preferably greater than 35%, and most preferably greater than 50%.
- an elongated element comprises an elastic material
- the momentum transferred to the golf tee can be at least partially absorbed by the elastic, elongated element, reducing the possibility that the golf tee is seriously deformed, broken and/or catapults away.
- the aforementioned ranges of the dimension of the elongated element refer to the original dimension without elastic deformation.
- the elongated element may also be composed entirely of an elastic material.
- the expression “A comprises material B” should be interpreted as also suggesting the case where “A is composed entirely of material B” unless otherwise specified.
- one or both of the elongated elements comprise one or a combination of suitable elastomers.
- Such elastomers may be any natural or synthetic rubbers which possess the aforementioned deformability or elasticity characteristic.
- the elastomers have other properties like waterproofhess for being used in circumstances such as on the grass of a golf course or on a synthetic mat at a driving range.
- neoprene also known as polychloroprene or pc-rubber
- the elongated elements, and preferably the entire tee holding device is made from a material or materials that is/are one or a combination of: environmentally friendly, sustainable, recyclable, biodegradable, compostable, natural. Since the tee holding device of the present invention might be forgotten or lost during or after use, it is advantageous if the materials employed in the device do not cause any harm to nature and are preferably compostable or biodegradable.
- the tee receiving section may comprise the same material as the elongated elements and may, as mentioned above, be integral with the elongated elements.
- each of the two tactile markers is removably connected to one of the two elongated, deformable elements, respectively.
- Said removable connection may be achieved by one or a combination of the following: magnet, hook-and-loop fastener, plug-in connector, clip, indent or recess.
- Each tactile marker is preferably connected to the second end of one of the deformable elements so as to be positioned at or proximate to said second end.
- the positions of the two tactile markers and the tee to be received in the tee receiving section form a, preferably isosceles, triangle.
- the length of the base of said triangle is preferably at least 15 cm, more preferably at least 18 cm, even more preferably at least 20 cm and/or preferably at most 30 cm, more preferably at most 27 cm and even more preferably at most 25 cm.
- the length of each of the legs of said triangle amounts preferably to 10 to 100 cm, more preferably to 20 to 75 cm and even more preferably to 30 to 50 cm.
- the most preferred means for providing the removable connection between each of the two tactile markers and the two elongated, deformable elements is a magnet which may be incorporated into either of the tactile marker and the second end of the elongated, deformable element.
- the other one of these two corresponding parts may also comprise a magnet or a magnetizable material such as iron.
- Such a magnetic connection provides several technical advantages because the force is well-defined and acts on a rather short length scale. Moreover, a hit and displaced tactile marker can be easily reattached without the need to fiddle with a mechanical connection means. In addition, a magnetic connection is aesthetically pleasing and can even be completely hidden behind a covering layer of, e.g., cloth. Very strong forces may be achieved by the use of, e.g., neodymium magnets.
- the removable connection by, e.g., a magnet, allows for easy and proper positioning of the two tactile markers with a well-defined force to be overcome when the golf club hits one of the tactile markers.
- the string or ribbon allows for tethering the tactile marker and prevents it from flying away once struck by a golf club, thereby saving the time and labour required to locate and retrieve the tactile marker when practicing.
- the string or ribbon is elastic.
- the string or ribbon has a spring constant greater than 0.5 N/cm, preferably greater than 1 N/cm, more preferably greater than 2 N/cm and/or smaller than 20 N/cm, preferably smaller than 10 N/cm, more preferably smaller than 5 N/cm.
- the spring constant for small extensions may be measured by attaching a weight to one end of the string or ribbon and measuring the extension caused by said weight.
- the string or ribbon has a length greater than 3 cm, more preferably greater than 5 cm and even more preferably greater than 7 cm.
- the string ribbon has a length smaller than 12 cm, more preferably smaller than 10 cm and even more preferably smaller than 8 cm.
- the tactile marker should preferably be light-weight with the weight of each tactile marker being preferably smaller than 10 g, preferably smaller than 5 g and even more preferably smaller than 3 g.
- the tee receiving section includes a coupling element configured to engage with the golf tee so that the golf tee is retained within the coupling element during an impact, i.e. when the golf tee is struck by a golf club. While a golf tee can be held by the tee receiving section even without a coupling element (e.g. by simply piercing the golf tee through the tee receiving section), providing a coupling element may be preferable in view of e.g. durability of the tee receiving section.
- the coupling element may be embodied in various configurations, as long as the aforementioned purpose is fulfilled.
- the coupling element may be a hole formed in a segment of material (i.e. the tee receiving section).
- the coupling element may be any structure extending from the tee receiving section, the structure being e.g. a ring, a hook or at least one strap.
- the coupling element is configured to firmly grip the golf tee by e.g. a friction force between the coupling element and the golf tee, so that the golf tee would be kept with the tee holding device after a golfer hits the golf tee.
- a diameter of that hole may, for example, be equal to or smaller than the dimension of the part of the golf tee engaged in that hole, so as to realize the aforementioned firm gripping.
- the tee receiving section includes two or more holes differing from each other in dimension and/or shape for receiving golf tees having different shapes and/or dimensions.
- the tee receiving section comprises a hole for inserting a golf tee, preferably a hole for inserting a regular golf tee and/or a hole for inserting a range tee. Accordingly, the golf training device can be suitably used on different grounds that require different golf tees.
- the tee receiving section may also combine a hole with a coupling element other than a hole.
- each of the elongated elements has at the second end thereof a hole for receiving an anchoring member, so that each of the elongated elements can be affixed to the ground by the anchoring member.
- the anchoring member will be described in more detail later.
- a coupling element suitable for engaging with the anchoring member is provided at the second end of the elongated element.
- Such a coupling element may take the form of a ring, a hook or at least one strap, as described above with respect to the coupling element of the tee receiving section.
- At least one of the aforementioned holes i.e. the hole(s) in the tee receiving section and/or at the second end of the elongated element, is provided with an eyelet for reinforcing the hole.
- the visual guide is preferably approximately V-shaped or U-shaped.
- the legs may return into their relaxed state if simply laid onto ground. Yet, the second ends of the elongated elements may be fixed to ground by means of the anchoring members discussed above. Thus, the distance between the two tactile markers may be optimized and maintained by the user.
- the tactile markers have a height of at least 2 cm, more preferably at least 2.5 cm and even more preferably at least 3 cm.
- the tactile markers have a height of at most 8 cm, more preferably at most 7 cm and even more preferably at most 6 cm.
- the tactile markers may also have different heights since it may be necessary to move the golf club over one of the two tactile markers during a swing.
- one of the tactile markers has a height of at least 2 cm, preferably at least 2.5 cm and more preferably at least 3 cm and/or a height of at most 4 cm, preferably at most 3.5 cm and even more preferably at most 3 cm.
- the other of the tactile markers has a height of at least 5 cm, preferably at least 5.5 cm and more preferably at least 6 cm and/or a height of at most 9 cm, preferably at most 8 cm and more preferably at most 7 cm.
- the invention is directed to the use of any of the aforementioned golf training devices.
- the use, or the method of using the golf training device includes the steps of laying down the golf training device, optionally affixing the second ends of the two elongated, deformable elements to the ground and inserting a golf tee into the tee receiving section.
- the tee receiving portion is affixed to the ground by inserting the golf tee into the tee receiving section and further into the ground.
- the method of using the golf training device further includes a step of arranging the tee receiving section and the two elongated elements so that the visual guide forms a V- shape or U-shape.
- the V- or U-shape may correspond to an isosceles triangle or a scalene triangle.
- An edge of the V- or U-shape may be straight or curved.
- the V- or U-shape defines a route extending along a longitudinal direction of the tee holding device, i.e. from a top to a bottom of the “V” or “U”, which, preferably, is arranged to correspond to an ideal swing direction/swing arc/swing path.
- the V- or U-shape thereby provides guidance for an ideal swing when a golfer is to hit a drive with the aid of the tee holding device.
- a golfer should swing the golf club in a manner that the clubhead travels along a route defined by the V- or U-shape, through the “entrance” defined by the two anchoring members and toward the vertex where the golf tee is located. Due to the deformability of the two elongated elements, the shape of the V or U as well as the opening angle may be easily adjusted.
- the V- or U-shape is arranged to correspond to an inside-to-inside swing path, an inside-out swing path or an outside-in swing path. That is, the golf training device can be used to teach a golfer to hit a straight shot, a draw shot and a fade shot.

- Fig. 3 is a schematic diagram illustrating the use of a golf training device according to an embodiment of the invention
- Fig. 4 is a schematic diagram illustrating the use of a golf training device according to an embodiment of the invention for practicing drive shots with side spin (draw/fade);
- Fig. 5 is a schematic diagram illustrating the manufacturing of a golf training device according to an embodiment of the invention.
- Fig. 1 shows a golf training device 100 according to an embodiment of the invention.
- the golf training device 100 includes a tee receiving section 102 and two elongated, deformable elements 104, 106.
- a first end 104a of the elongated element 104 is connected to the tee receiving section 102.
- a first end 106a of the elongated element 106 is connected to the tee receiving section 102.
- Two holes 108 and 110 are formed in the tee receiving section 102.
- the smaller hole 108 may be suitable to engage with a golf tee typically used on a golf course
- the bigger hole 110 may be suitable to engage with a rubber golf tee typically used with a synthetic mat on a driving range.
- the embodiment shown in Fig. 1 comprises two holes 108, 110, only one of the two holes or more holes at different locations or of different types may be provided.
- An optional hole 114 engageable with an anchoring member is formed at a second end 104b of the elongated element 104 and a similar optional hole 1 16 engageable with another anchoring member is formed at a second end 106b of the elongated element 106. While not shown in Fig. 1, one, some or all of the holes 108, 110, 114 and 116 may be provided with an eyelet for reinforcement.
- visual guidance could alternatively also be achieved with a U- shaped visual guide or a visual guide having any other shape comprising two elongated, deformable elements which could help to provide optical guidance to the golfer.
- the visual guide could have the shape of a rectangular U having two parallel elongated, deformable elements and a substantially straight tee receiving section being oriented perpendicular to the two elongated elements.
- the visual guide does also not need to be symmetric and may have, e.g., two elongated, deformable elements of different shape and/or size.
- the golf training device 100 further comprises two tactile markers 118, 120, which can be better seen in the side view shown in Fig. 2, which tactile markers 118, 120 are connected to the two elongated, deformable elements 104, 106, respectively.
- a removable connection between the tactile marker 118 and the second end 104b of the elongated, deformable element 104 is achieved by two magnets 128, 130 being embedded in the tactile marker 118 and the elongated element 104, respectively.
- the tactile marker 118 of the embodiment shown in Figs. 1 and 2 is also attached to the elongated, deformable element 104 by means of a string or ribbon 122.
- the tactile marker 120 is attached to the elongated element 106 by means of a string or ribbon 124.
- the impact force will overcome the magnetic force between the two magnets 128 and 130 such that the tactile marker 118 is catapulted away.
- the tactile marker 118 is attached to the elongated element 104 by means of the string or ribbon 122, which is preferably elastic, the tactile marker 118 does not get lost and remains linked to the golf training device. Ideally, most of the impact onto the tactile marker 118 is compensated by the air resistance and the elastic force of the string or ribbon 122.
- tactile markers 118, 120 of the embodiment shown in Figs. 1 and 2 have a substantially elliptical cross section
- other shapes and sizes of tactile markers are envisaged as well.
- the cross section of the markers may by round, rectangular or polygonal and the shape of the markers may be cylindrical, pyramidal, spherical and the like.
- the golf training device 100 may be affixed to the ground by inserting anchoring members 200 (see Fig. 3) through the holes 114, 116 at the second ends 104b, 106b of the elongated elements 104, 106, and inserting a golf tee 300 through the corresponding hole 108 in the tee receiving section 102.
- a golf ball 400 is placed on the golf tee 300.
- a golfer can then hit a drive with a golf club 500.
- the golf tee 300 may held and retained by the golf training device 100, and does not catapult away even if the golf club 500 strikes the golf tee 300.
- the golf training device 100 provides guidance for the golfer to swing a correct arc for an ideal shot. For example, by following the route 600 that corresponds to a straight (i.e. inside-to- inside) swing direction, a golfer can hit a drive with such swing direction that may eliminate any undesirable sidespins.
- the golf training device 100 may have a bright color so that it is highly visible against the green color of the grass or artificial grass on the driving range, and its image, therefore, “bums” into the mind of the golfer after repetition of practice. In this way, when playing the game formally, the golfer could take the golf training device 100 mentally with him onto the golf course, thereby helping him to swing the golf club in a correct arc for a good shot, even without the physical presence of the golf training device 100.
- the opening angle of the V-shape the closer the two markers 300 are to each other the more challenging it becomes to perform the swing without touching the tactile/audible markers, thus resulting in an even more precise repetition of the swing when striking the ball, and/or gradually increasing the swing precision over time as the player improves.
- the golf training device 100 can also be laid down in such a way that it guides a correct swing arc for a “draw” or “fade” shot, which is a shot that gently curves from the straight path due to slight sidespin. Contrary to the undesirable slices and hooks, draws and fades are controlled, intended shots that require advanced skills. Golfers usually spend a great deal of time on the driving range with professional trainers in order to perfect the draw and fade shots. With the golf training device 100, golfers may now train themselves to be acquainted with a correct swing for a draw and a fade and learn to hit them consistently, as described below.
- the golf training device 100 can further be used to guide a golfer to “shape” his shots, i.e. to hit the golf ball 400 with a controlled amount of sidespin, so that the golf ball 500 has a controlled curve as either a draw or a fade.
- the golf training device 100 is arranged so that the V-shape corridor only allows the golf club 500 to strike the golf ball 400 coming along an inside-out path (for a right-handed golfer), which generally imparts counter-clockwise sidespin on the golf ball 400, and accordingly generates a controlled draw.
- a fade shot can be created with an outside-in swing path, which generally imparts a clockwise sidespin on the golf ball 400.
- a golfer may hit a first drive with a first swing direction lead by a first route defined by the V-shape, and, should he find the trajectory non-ideal (e.g. due to either too much or not enough side spin), adjust the shape and/or orientation of the V-shape so that the V-shape defines a second route corresponding to a second, improved swing.
- the golf training device 100 of the present invention may be manufactured by bisecting a portion of an elongated strip along the dashed line shown in Fig. 5 and punching the holes 108, 110, 114 and 116 in the elongated strip. A further hole may be punched for the magnet or other connection means and a snap fastener may be provided for attachment by means of the string or ribbon (not shown in Fig. 5).
- the present invention further provides a golf accessory kit including the golf training device 100 of Fig. 1 and two anchoring members 200 as shown in Fig. 3.
- the anchoring member 200 includes a marker 202 bound to a pin 204.
- the pin 204 is suitably sized and shaped to be able to pass through hole 114 provided at the end 104b of the elongated element 104.
- the marker 202 has a dimension greater than a width of the pin 204 (the width being a dimension along a direction perpendicular to the longitudinal direction of the pin 204), and also greater than a diameter of the hole accommodating the pin 204.
- the marker 202 is not limited to any particular shape.
