Description
Golf putting trainer
TECHNICAL FIELD
The present invention relates to a golf putting trainer comprising a holder for a putter having a shaft and a head, means for guiding the holder in a curved movement path and means for holding the putter head in a position perpendicular to the direction of movement of the holder.
BACKGROUND OF THE INVENTION
On a golf round about 45% of the strokes are putting strokes. It is thus essential to put good in order to be a good golfer.
In a correct putting swing the head of the putter is perpendicular to the putting line when the ball is hit. If the head is not peφendicular to the putting line the ball will spin and move away from the putting line. A golf green is however seldom totally horizontal which means that gravity influences the path of the ball. Thus, a person performing a putting stroke will therefore have difficulty in determining if path of the ball is due only to influence by gravity or if spin also had an influence.
There is therefore a need for a golf putting trainer in which a correct putting swing can be teached.
Several golf putting trainers are known. JP 2000300709 A discloses such a trainer in which a putter head is movable along a guide rail with the head rotatable around a vertical axis a certain degree. This trainer is said to make the user feel if an incorrect putting swing is performed. JP 6126010 A
discloses such a trainer in which a holder for a putter is guided by arcuate rails.
The object of the present invention is to provide an improved golf putting trainer, in which a putter is moved in a path that can be vertically and horizontally curved, the curvature of the path being adjustable in order to adapt the trainer to the length and constitution of the user.
SUMMARY OF THE INVENTION
The object of the invention is obtained by a golf putting trainer comprising a holder for a putter having a shaft and a head, means for guiding the holder in a curved movement path and means for holding the putter head in a position peφendicular to the direction of movement of the holder, characterised by means for adjusting the curvature of the movement path of the holder both vertically and horizontally. By this possibility of adjusting the curvature, the putter can be made to follow the correct putting swing movement for the individual using the trainer.
In a preferred embodiment, the means for guiding the holder comprises two parallel elongate guide rails supported by a frame, the rails being attached to the frame in their forward and rear ends and in a point therebetween. Furthermore, the trainer has means for adjusting the vertical and horizontal position of the ends of the guide rails which are arranged to move the forward or rear ends synchronously so that the guide rails always be parallel to each other. The means for guiding the holder comprises means for preventing rotation of the holder around the axis of the putter shaft and out of a plane comprising the two parallel rails.
In a first alternative, the means for guiding the holder comprises rollers running on a surface of the rails, wherein at least two rollers being displaced vertically and horizontally in relation to each other are associated with each rail.
In a second alternative, each rail comprises a groove running along the length thereof, in which rollers protruding from the holder are guided.
Advantageously, a mirror is attached to the holder and located in a plane parallel to the plane comprising the rails.
In the first embodiment the holder comprises a vertical wall being peφendicular to the elongate rails and means for removably affix the stroking face of a putter head to said wall, said wall comprising an opening for the part of the putter head comprising the sweet-spot of the putter head.
In a second embodiment of the invention, the putter is integrated in the holder.

DESCRIPTION OF EMBODIMENTS
A golf putting trainer according to a first preferred embodiment is shown in figures 1-7. This trainer comprises a frame 1 for supporting two parallel, elongate guide rails 2 for a holder 3, in which a putter can be removably affixed. The frame 1 comprises two parallel elongate beams 4 or the like and an upstanding end part, a front end part 5 and a rear end part 6, the end parts 5,6 being attached to the front and rear ends of the beams 4. Each guide rail 2 is affixed to the adjacent beam 4 in a middle point 7 of the beam and the ends of the rails are supported by adjustment devices 8,9 arranged in the front and rear end parts 5,6 of the frame 1 to be movable in a vertical and horizontal direction. In the shown example the rails have the form of tubes having a circular section but the tubes can of course have other sections, such as square or rectangular sections. Furthermore, the rails need not be hollow and can consist of rods.
In figure 2 and 3 the adjustment device 9 arranged in the rear end part 6 is disclosed. The adjustment device 9 comprises a transversely extending rod 10
which ends are slidable in a vertical plane peφendicular to the length direction of the beams 4 in vertical slots 11 provided in the vertically extending side beams 12 of the rear end part 6. This rod is rotatably supported in a transverse bar 13 having downwards directed flanges 14 abutting the insides of the side beams 12 of the rear end part 6. The bar 13 is in the middle thereof provided with a nut 15 co-operating with a threaded bolt 16 being rotatably supported in the upper crossbeam 17 of the rear end part 6. By rotating the head 18 of the bolt 16 in opposite directions the bar 13 and thereby the rod 10 can be moved upwards and downwards in the slots 11.
The adjustment device 9 also comprises two attachment rods 19 for attaching the rear ends of the rails 2 to the adjustment device. The rear ends of these attachment rods are supported by the transverse rod 10 which run through holes 20 in the rear end portions of the attachment rods 19. The rear end portions of the attachment rods 19 also comprises holes peφendicular to the holes 20 in taps 21 are provided. These taps 21 are affixed to a sleeve 22 having holes corresponding to the holes 20 for the passage of the transverse rod 10 and threaded holes for the affixing of the taps 21. The transverse rod 10 is threaded at least in parts and the undersides of the taps comprise threads co- operating with the threads on rod 10. The outer ends of the rod 10 are provided with heads 23. By rotating these heads 23 the attachment rods 19 can be laterally moved back and forth. The holes 20 have the form of a double cone with bases directed outwards in order to permit angular displacement of the attachment rods 19 in relation to the rod 10. The rear end portions of the rails 2 are slidably attached to the attachment rods 19.
The adjustment device 8 for the front ends of the rails 2 is constructed in the same way as the adjustment device 9 for the rear ends of the rails 2 and need not be described further.
Figures 4-7 show a first preferred embodiment of the holder 3 for a putter. The holder 3 comprises a front wall 24, a rear wall 25, two side walls 26,27 and a bottom wall 28. The front wall 24 has an opening 29, in which the central part of a putter head is to be placed. A resilient element 30 is protruding upwards from the bottom wall 28 on both sides of the opening 29 in the front wall and a self-locking band 31 such as a Velcro™ band co-operating with each element 30 is attached in the front wall and can operated to press this element downwards. Thereby a putter head placed between the elements 30 can affixed to the holder 3 with its stroking face pressing against the front wall and its bottom face pressed against the bottom wall 28. The resilient element 30 can for example be a metal piece. In the bottom wall two rows of openings 32 for accommodating the elements 30 are arranged so that the location of these elements can be adapted to the type of putter head to be attached to the holder.
On the side walls 26, 27 of the holder, rollers 33,34 and 35 are arranged to cooperate with the rails 2 so that the holder is unable to rotate in or move out of the plane comprising the rails 2. This is accomplished by displacing the rollers 34,35 from the roller 33 both vertically and lengthwise.
The described putting trainer functions in the following way.
Firstly, the trainer is adapted to the individual who is to use the trainer. For a long individual the radius of the swing is larger than for a shorter individual provided they use the same putting grip. This means that for a short individual the ends of the rails 2 must be higher up than for a long individual. The ends of the rails 2 are also adjustable sideways, i.e. laterally in relation to the length direction. However, the differences of the radius of the swing in a horizontal
plane are much smaller than for the differences of the radius in a vertical plane.
After the trainer has been adapted to the individual using it, the head of the putter attached to the holder will always follow the correct movement path, hitting the ball in a position peφendicular to the putting line, i.e. a line parallel to the length direction of the rails 2. When the ball is hit by a correct putting stroke, the head of the putter should be slightly above ground. This means that in the lowest position during its movement, the bottom of the holder should almost touch the ground. Therefore, the rails 2 are placed within the height region of the beams 4 of the frame in their attachment points 7 and a distance on the front and rear sides thereof. In order to allow movement of the rails 2 in a direction peφendicular to the rails 2, the rails are distanced from the beams 4 and attached thereto via distance elements 36, as can be seen in figure 1.
Thus, a putter attached to the holder 3 will always perform a correct putting stroke. All the individual using the trainer has to do is to grip the shaft of the putter, swing and follow the movement of the putter. A correct putting stroke will thereby be learned by motor learning.
The holder 3 is advantageously also provide with a horizontally disposed mirror 37 having a marking in the middle thereof representing the position of the sweetspot of the putter. This makes it possible for the user to check that he has his/her eyes directly above the ball, which is essential for the aim. When the trainer is used together with a ball, the ball should be placed in the middle of a line between the attachment points 7 of beams 4.
In figure 8 a holder 3' according to a second embodiment of a putting trainer is schematically shown. The putting trainer according to the second
embodiment differs from the putting trainer according to figures 1-7 only in that a putter is integrated in the holder and that the side walls only support two rollers 33 ', 34' instead of three rollers as in the first embodiment. Otherwise this trainer is constructed in the same way as the trainer according to figures 1- 7 and need not be further described. The putter integrated in holder 3 ' has a shaft 38 protruding from the front wall 24', which thereby constitutes the putter head.
The described embodiments can of course be modified in several ways without leaving the scope of the invention. For example, the rails can have grooves along the length thereof, in which rollers are guided. Furthermore, resilient clamping devices or other means can be used to attach a putter head to the holder. The attachment rods can be made angularly displacable with the aid of universal joints instead of holes having the form of double cones or by being made of a bendable material. The attachment rods need no be rods but can be tubes fitting onto or into the end portions of the rails. The bottom wall of the holder can consist of one or several bars instead of a plate as in the disclosed embodiments. The adjustment devices can be different from the described devices, for example can the front and rear end parts of the frame be laterally movable as a whole in order to accomplish the sidewise movements of the rail ends and the side beams of the front and rear end parts can be made of two telescopic portions. The scope of invention should therefore only be restricted by the content of the enclosed set of patent claims.
