Description

PCT/AU00/00621 Received 07 June 2001 -1- APPARATUS AND METHOD FOR PUTTING PRACTICE The present invention relates to an apparatus and method for practicing golf putting.

Existing apparatuses for practising putting include a convex plate, provided with a central depression and a rear wall. Such devices are placed on the floor and a user attempts to putt a golf ball into the depression. The rear wall is provided to prevent golf balls from overshooting the device: this minimizes the movement required to retrieve the ball. A more complex device includes a return mechanism, whereby any golf ball entering the device is channelled towards a piston or lever which is activated by the ball's presence to propel the ball from a race or chute, generally located in the front of the device.

The former device described above has the advantage of simplicity, but golf balls are not returned to the user.

This is overcome in the second device, but with considerable complexity and expense. It is also necessary to power the return mechanism, often by electrical battery or with a manually wound clockwork mechanism.

Further, existing devices do not return the golf balls in the general direction of the user.

According to the present invention, therefore, there is provided an apparatus for putting practice comprising: a golf ball return surface having a downwardly concave curved trough running from a first end of said return surface to a second end of said return surface, said first end for locating on a putting surface; and support means for supporting said return surface so as to be inclined to said putting surface with said second end above said putting surface.

Preferably the first end is curved so that said return AMENDED SdHi

IPEA/AU

PCT/AU00/00621 Rteceived 07 June 2001 2 surface more readily forms extended contact with said putting surface when said return surface is located on and inclined to said putting surface.

Thus, the inclined surface provides a surface against which a user may putt a ball, and from which the ball will roll back towards the user. The trough biases the direction of the ball's return towards the user, whether or not the ball hits the apparatus centrally. The first end is preferably curved so that especially when the material from which the apparatus is made is relatively stiff it will be in extended contact with the putting surface, ideally with the edges of the first end in contact with the putting surface.

If the material is somewhat softer, the weight of the return surface may be sufficient to provide this extended contact, as this weight will deform the otherwise unsupported edges into contact with the putting surface.

Preferably the apparatus is provided with an indicium at or adjacent to said first end and located centrally thereto as a target for aiming a ball towards.

This indicium makes it clearer to the user where he or she should aim the ball (and serves as the notional hole).

Preferably the apparatus includes a target aperture for fully or partially receiving said golf ball.

Preferably said apparatus includes a back wall, most preferably at or adjacent to said second end.

Thus, balls hit with excessive force may nevertheless be returned to the user.

Preferably said support means engages said return surface at or adjacent to said second end. Preferably said support means comprises a curved sheet.

In order that the present invention may be more clearly ascertained, a preferred embodiment will now be described, by way of example, with reference to the accompanying drawing, in which: Figure 1 is a perspective view of a putting aid according to a preferred embodiment of the present invention; and Figure 2 is a side elevation of the putting aid of figure 1; Figure 3 is a view of the aid of figure 1 folded flat; Figure 4 is a perspective view of a putting aid according to a further preferred embodiment of the present invention view folded flat; and Figure 5 is a perspective view of the putting aid of figure 4 in assembled configuration.

A putting aid in accordance with a preferred embodiment of the present invention is shown generally at 10 in figure i.

The aid 10 includes a downwardly troughed inclined sheet 12 of stiff card. The first, lower end 14 of sheet 12 is concave so that, when the aid 10 is placed upon a flat surface, lower end 14 will be in contact with that surface despite the troughed profile of sheet 12.

The putting aid 10 also includes a curved support 16 located at second or upper end 18 of sheet 12. Support 16 includes an upwardly extending wall 20 which projects above sheet 12.

Sheet 12 further includes an indicium in the form of a crescent-shaped region 22 adjacent to first end 14.

Figure 2 is a side elevation of the putting aid 10. The troughed nature of sheet 12 is readily apparent in this AMENDED SHEE1

IPENAU

WO 00/72924 PCT/AU00/00621 5 view; the lower peripheral 12a corresponds to the longitudinal centre line 12b of the sheet 12.

In use, the putting aid 10 is placed on a suitable playing surface, and a user practises putting by putting a golf ball towards region 22 and hence upwardly along sheet 12.

If a golf ball is hit with excessive force, wall 20 will in many instances stop the ball, and the ball will then roll back down sheet 12. Otherwise, the ball will roll some distance upwardly along sheet 12, and then roll back down sheet 12 and from the aid 10 towards the user.

Advantageously, if the user hits the golf ball from a location aligned with mid-line 12b of sheet 12, but misses target region 22, the troughed form of sheet 12 will tend to redirect the golf ball back towards mid-line 12b and therefore return the ball to the vicinity of the user.

Alternatively, if the user hits the ball towards the putting aid 10 from a position that is not aligned with mid-line 12b, the troughed form of sheet 12 means that the ball will nevertheless encounter a similar gradient to one hit from an aligned position, and so be again returned to the general vicinity of the user.

Figure 3 shows the putting aid 10 of figures 1 and 2 folded flat. It can be seen in this figure that the second end 18 is formed when the flattened aid 10 is folded along dashed lines 18a (which are preferably scored). These lines are not co-linear or parallel, and so folding support 16 downwards forces sheet 12 into the troughed configuration shown in figures 1 and 2. This also lifts wall 20 into its upward position, as also shown in figures 1 and 2.

Once folded into the configuration shown in figures 1 and 2, the putting aid 10 will stand without assistance on a surface, such as carpet, with sufficient friction.

However, on smoother surfaces, such as a wooden floor, it WO 00/72924 PCT/AUOO/00621 6may be necessary to maintain support 16 and sheet 12 in the relative configuration shown in figures 1 and 2 by means of tape or some other elongate element attached, preferably, from the lower extremity of support 16 to the under-side of sheet 12. This may be unnecessary in other embodiments where the entire putting aid is moulded from, for example, plastic, or made of some other material such as light steel sheet that would resist collapsing flat. However, such embodiments would lack the advantage of that illustrated in 1C figures 1 to 3 of being able to be folded flat for storage or transport.

A putting aid in accordance with a further preferred embodiment of the present invention is shown generally at 24 in figure 4, which is a perspective view of the putting aid 24 folded flat. Putting aid 24 is generally similar to the putting aid 10 described above; like numerals indicate like features.

Putting aid 24 is of polypropylene of approximately 1.4 mm thickness. It differs from putting aid 10 in that lower end 14 is considerably less curved (and, in fact, is optionally straight) and is provided with additional score lines to assist the assembly process. In putting aid 24 dashed lines 18a indicate score lines, and additional score lines 18b are provided from the inner ends of score lines 18a to end 15 (that is, the end opposite lower end 14).

Score lines 18b marginally converge as they run from score lines 18a to end 15. In addition, sheet 12 includes two score lines 32, each from near (approximately 2 cm) a respective lower corner 14a of sheet 12, to the point at which a respective pair of score lines 18a, 18b intersect, but ending in each case approximately 9 cm from that point of intersection.

These score lines encourage the putting aid 24 to bend along score lines 18a, 18b and 32 so that when the WO 00/72924 PCT/AU00/00621 7 putting aid 24 is assembled the preferred configuration (shown in figure 5) is obtained. The use of this combination of score lines, moreover, reduces the force required by a user to effect this assembly.

Putting aid 24 also includes an approximately semi-circular cut 26 located adjacent to (or, when assembled, below) end wall 20. This cut 26 defines a retaining means in the form of semi-circular tongue 27 which, when the putting aid 24 is assembled, engages sheet 12 resiliently and thereby maintains the assembled configuration without requiring additional support (such as the elongate element referred to above). An elliptical target aperture 28 is provided adjacent to the centre of curvature of cut 26. Target aperture 28 is smaller than a golf ball, but large enough to represent a realistic target for the user, as will be described in more detail below.

The putting aid 24 also includes, near end 15, a hanging aperture 30 so that putting aid 24 can be stored folded flat and hanging from a hook.

Referring to figure 5, putting aid 24 is assembled by folding the putting aid 24 along the various score lines, so that sheet 12 forms a trough and upper end 18 of sheet 12 is supported above a playing surface by support 16, resting on end 15. Tongue 27 (at this point projecting downwardly) is bent forwards towards lower end 14) and upwards until impeded by the under side of sheet 12, then bent through the gap between support 16 and sheet 12 and released thereby pressing resiliently downwards against sheet 12 and urging wall 20 away from sheet 12. As wall extends above sheet 12, this, in effect, applies a moment to wall 20 and thereby support 16 that maintains the putting aid 24 in the assembled configuration shown in figure 8 In this configuration, target aperture 28 is located marginally beyond the upper periphery of sheet 12.

A user can use putting aid 24 essentially in the same manner as he or she would use putting aid 10. In addition, however, the user can aim a golf ball at target aperture 28 and, if the ball is hit in the appropriate direction and (unlike putting aid 10) with the appropriate force, the ball will stop in target aperture 28. The provision, therefore, of target aperture 28 provides an additional form of practice for the user that depends on the force with which a ball is struck as well as the direction in which the ball is hit. The ball can then be dislodged by an appropriately struck subsequent ball.

When the user has complete his or her putting practice, tongue 27 can be pushed downwardly past sheet 12, thereby releasing the urging of wall 20 and support 16 into the assembled configuration and allowing the putting aid 24 to be again folded flat as shown in figure 4.

Modifications within the spirit and scope of the invention may readily be effected by a person skilled in the art.

Consequently, it is to be understood that the invention is not limited to the particular embodiments described by way of example hereinabove.
