Patent Application
20230302337
The invention relates to the fixing of supports for a golf ball, in particular a golf tee. Thus, the present invention relates in particular to an apparatus for fixing golf tees.
A ‘tee’ in golf, also called a ‘golf tee’, is a small pin made, for example, of wood or plastic or a combination of the two aforementioned materials, which is typically inserted into the ground during teeing and onto which the ball is then allowed to be placed (‘teed up’). The ball is thus raised and is usually easier to play. The ball is only allowed to be teed up for the first swing of each hole.
For the sake of completeness and overall understanding: the teeing ground per se, that is the rectangular and mostly raised lawn area at the start of each hole, is usually also referred to as the ‘tee’. However, the latter is not directly related to the present invention, which rather relates to the previously described pin-like ‘golf tee’.
An exemplary ‘standard’ tee is 2⅛ inches (about 5.4 cm) in length. The maximum length is usually limited to 4 inches (10.16 cm). Extra-long tees are particularly used for swings with a driver (wood 1). During the cold season, for example, flat winter tees made of plastic are used since standard tees can no longer be inserted into the hard ground.
Such apparatuses are intended to prevent the golf tee from flying off in the event of an unintended hit by a golf club and then a cumbersome search for its retrieval. Typically, beginners of golf, inter alia, will hit golf tees directly during the swing, shooting them far, for example into a bunker, where they are very hard to find. This is inefficient, a waste of material and environmentally unfriendly, for example due to the increased plastic waste.
The prior art provides a number of possible solutions for such apparatuses:
DE 20 200 7 005 698 U1 proposes a leather tape, a textile tape, a plastic tape, etc. for this purpose, which is connected at one end via a loop fastening to the golf tee and at the other end is provided with a fastening anchor which is pressed into the ground.
It is understood that there is a stable fixation, but also that it can be detached from the ground, with the effect of greater energy dissipation and thus a short flight path.
DE 20 2006 013 572 U1 discloses connecting a plurality of golf tees to one another and to a ground anchor. The ground anchor is simultaneously the receiver for the spout, i.e., it is a split golf tee and not a one-piece golf tee.
US 2018/0 326 269 A1 provides the arrangement of a plurality of golf tees connected by a common tether.
The tether can be fastened via holes in the golf tees, or the tether is fixed by means of a barrel which is slid over the tee shaft in order to achieve clamping between the barrel and the tee shaft by capturing the tether.
Finally, reference should be made to US 2013/0 005 511 A1, which describes a rewindable golf tee. The golf tee is connected via a link to a rewinding device which is wound and unwound.
At least the rewinding process takes place in a damped manner. The link and the golf tee are connected via a bore or eyelet in the golf tee.
The rewinding device may be further equipped with the following elements: a pitch mark repairer, a ball marker, a groove cleaner, a replacement T-piece, a pencil or a score keeper.
The considerable disadvantage of the mentioned apparatuses is that special golf tees are provided, specifically provided with bores, eyelets or also clamping barrels. Furthermore, the number of golf tees and their spacing from one another is predetermined or the spacing can only be varied within limits by untying or retying the tether to the eyelet, for example. In addition, different tee shafts cannot be handled. This is not very user friendly.
An object of the invention is now described below. An object of the invention is to fix any number of golf tees with different, virtually freely selectable spacings and any shaft diameters. This object is achieved with the features of Claim 1. Advantageous embodiments are the subject matter of the dependent claims.
It is a further object of the invention to convert the impact force of the golf swing to the tee into a rotational movement of the tee fixation and thus also of the tee tape via the apparatus according to the invention for golf tee fixation, such that the force application to the tee is rapidly attenuated and it can be better retained in the tee holder in order to fix it flat in the holder and not to hit it away.
The apparatus according to the invention for fixing golf tees by means of a tape which can be wound and unwound and which, together with the winding and unwinding device, is arranged in a housing and to which at least one golf tee can be fastened, wherein the golf tee has a tee shaft for insertion into the ground and a plateau, arranged thereon, for a golf ball, the tape has openings arranged spaced apart in the tape longitudinal direction, which openings are visible and accessible when the tape is unwound, which penetrate the tape and into each of which a tee shaft of a golf tee can be frictionally inserted.
In one embodiment, the tape comprises one or more aforementioned openings, preferably at least two, even more preferably at least three openings, in the tape longitudinal direction. In the case of a plurality of openings, they may be the same size in diameter or have a different diameter per opening. In the case of a plurality of openings, they may all be equally spaced apart or be differently spaced apart from one another.
The openings can therefore have different spacings or equal spacings or a combination of equal and unequal spacings and penetrate the tape preferably on the broad tape surface.
Furthermore, the internal dimensions of the openings can be equal or unequal or a combination of equal and unequal dimensions.
This configuration of the apparatus allows any number of golf tees to be connected to one another. The user can choose the optimum spacing between the golf tees for said user, and the golf tees are fixed by the applied frictional connection between the edge of the openings and the tee shaft in such a way that they do not detach from the tape when they are inadvertently struck by a golf club.
To achieve the frictional connection between the tee shaft and the inner edge of the opening, the following solutions are preferred:
In a third solution variant, the inner edges of the openings are surrounded by a highly elastic material which expands primarily in the plane of the tape when the tee shafts are inserted and thus clamps the respective tee shafts. Tee shafts with different diameters can be used.
These variants also function in tee shafts which do not have a circular cross-section. In all cases, the remaining size of the free cross-sectional area of the openings is smaller than the cross-sectional area of the golf tees to be inserted.
According to a further embodiment of the apparatus, the tape has a tongue at its end, which tongue projects out of the housing in the wound state of the tape. This tongue is used to pull out (unwind) the tape by hand.
At least one opening into which a tee shaft of a golf tee can be inserted is advantageously also arranged in this tongue. The opening preferably extends transverse or perpendicular to the tape longitudinal direction. This has several advantages. Firstly, a golf tee is provided with which the end of the tape can be fixed on the ground. Secondly, it is easier to grasp a golf tee than a tongue by hand when unwinding the tape.
According to a further embodiment of the apparatus, the tape has, at its end, in addition to/or as an alternative to a tongue, an end piece which likewise projects out of the housing in the wound state of the tape. This end piece, optionally with or without an additional tongue, is used, on the one hand, to pull out (unwind) the tape by hand, but additionally itself comprises at least one tee opening, preferably two, even more preferably three tee openings. That is to say, in the context of the invention, the aforesaid end piece can have one or more, preferably two, more preferably three, openings/holes as a tee holder. In this case, the openings themselves can all be configured to be identical or different. For example, two openings/holes can be smaller in diameter than a third opening and additionally be provided on the top and/or bottom with a protuberance, and thus receive different tees to those of the third opening. It is thus conceivable that said openings/holes with smaller diameters and protuberances on the top and bottom can receive conventional, narrow golf tees in a frictional and/or interlocking manner, whereas a third simple opening/hole without protuberances, but with a larger diameter, is designed so as to suitably receive and fix a conical golf tee. It is immediately clear to a person skilled in the art that there can also be a wide variety of technical embodiments of said openings/holes on the end piece in order to correspondingly adapt them to the preferred golf tees to be used, and in order to bring about a frictional and/or interlocking connection and thus a suitable fixing of the golf tee in the tee holder according to the invention. Thus, said openings/holes for the tee fixing can also have different, suitable wall thicknesses and/or elevations and/or materials.
The specified end piece can be made of an appropriately suitable material. For example, a flexible or semi-flexible material is suitable as long as the insertion and fixing of a golf tee by means of frictional and/or interlocking connection is made possible. A suitable material for the end piece is a silicone and/or a rubber material.
In one embodiment, the tee tape itself is a flexible or semi-flexible tape.
In the context of the invention, for example, the embodiments comprising a flexible tape and a flexible end piece are particularly well suited for converting the force application to a golf tee, when it is inadvertently struck, into a rotational movement of the end piece and of the flexible tape, whereby energy of the force application is dissipated and the golf tee is held in a fixed manner in its opening/hole. This means that the arrangement of the tape and end piece as well as the use of a flexible or semi-flexible material for them, such as silicone and/or rubber, enable particularly preferred fixing of the golf tee in the tee tape apparatus according to the invention.
In a further embodiment, the tee tape according to the invention comprises a holder which allows the tee tape to be fastened, for example, to the clothing of a user via a suitable cord, via a suitable band, for example rubber band, or by means of another suitable connecting means. For example, the tee tape can also be clipped by means of a clip via said holder.
In a further embodiment, the tee tape comprises an apparatus, such as a button, which allows the flexible tee tape to be retracted.
In order to stock a certain number of golf tees for insertion into the openings of the tape, according to a further embodiment, the housing has at least one, preferably a plurality of receptacles on the outside for the shafts of golf tees.
The tape itself preferably consists of an elastic material and/or of woven and elastically coated material. Further advantageous embodiments are directed to providing the apparatus with expedient additions for golf.
Therefore, according to the invention, the tape which can be wound and unwound is a tape measure with an inch and/or metric scale. This also makes it easier to individually determine the spacings between the golf tees.
Furthermore, the housing has a connecting element for detachably fastening it to a piece of clothing or another object.
The housing also allows an advertising space to be provided. It may also be provided with a circular spirit level to align the tees in two dimensions.
In a known manner, the housing can have a pitch mark repairer and/or a ball marker and/or a grove cleaner.
Furthermore, the housing can be provided with an LED that can be switched on and off.
The pitch mark repairer can additionally be used to fix the housing to the ground.
According to a further advantageous embodiment, the winding device can be driven by an electric motor in the housing. This has the advantage that the tape is not continuously accelerated when wound, as is the case, for example, with spring-driven winding devices, for which reason they are also provided with a damper.
In order to have the necessary energy for electrically operated components, according to a further embodiment the forces and movements occurring during the winding and unwinding of the tape can be used by means of an energy converter to charge an energy store in the housing.
The invention is explained with reference to the drawings. In the drawings:
The golf tees 6 have a tee shaft 7 for insertion into the soil and a plateau arranged thereon for a golf ball.
Prior to the insertion of the golf tees 6 into the ground, the tee shafts 7 are each inserted through an opening 3 of the tape 2 to produce a frictional connection.
The openings 3 are arranged in a spaced manner in the tape longitudinal direction 4. In this case, the openings 3 have different spacings or equal spacings or a combination of equal and unequal spacings.
In each of these arrangements of the openings 3, the user can set the spacing and the number of golf tees 6 in a way that is most optimal for the user's style of play.
In order to be able to use golf tees 6 with different cross-sectional areas and cross-sectional sizes, while retaining the frictional connection between the tape 2 and the golf tees 6, the inner edge of openings 3 is designed to be serrated, preferably star-like, or the openings 3 are designed to be slit-like or oval, or the inner edge of the openings 3 is provided with a highly elastic material. In all cases, the remaining size of the free cross-sectional area of the openings 3 is smaller than the cross-sectional area of the golf tee 6 to be inserted.
The tape 2 itself consists of an elastic material and/or of woven and elastically coated material which can be wound well. In this case, the winding device in the housing 1 is driven by an electric motor in order to ensure smooth winding. Of course, spring-loaded winding apparatuses are also possible.
So that the tape 2 can be grasped by hand for unwinding, its end has a tongue 10 which, in the wound state, projects out of the housing 1. This tongue 10 can also be equipped with one or more openings 3 for receiving a tee shaft 7.
The housing 1 has a connecting element, for example a snap hook, or just a lateral opening for detachably fastening it to a piece of clothing, a key fob or another object.
An advertising space 9 arranged on the housing 1 can be used, for example, to indicate the manufacturer or a special tournament.
Not shown is the further possible provision of the housing 1 with a ball marker and/or a groove cleaner and/or an LED that can be switched on and off and/or a circular spirit level.
When the opening 3 is penetrated, the serrations 8 are bent outwards in the insertion direction, clamping the tee shaft 7 and preventing withdrawal up to a certain level of force. Since the withdrawal movement means a change in direction of bending of the serrations 8, the clamping forces increase when the tee shaft 7 is pulled out of the opening 3.
Furthermore, it is shown that the tape 2 which can be wound and unwound is a tape measure with an inch and/or metric scale 5. This can be used by the user in an assisting manner for selecting the spacings between openings 3.
A further advantage of this embodiment is that tee shafts 7 with different cross-sectional areas can be used in the case of identical opening sizes. The differences in the dimensions or shape are compensated by the degree of bending of the serrations 12.
