This invention is directed to a method of recovering golf balls on a driving range, and to ball retrieving apparatus for carrying out the method.
In the operation of golf driving ranges the efficient retrieval of golf balls poses a problem for which prior solutions have been limited in their success.
Some of the problems encountered arise from the non-uniformity of the balls being retrieved which may be cut and of non-standard surface conditions, while the terrain of the range may vary widely. both in contour and surface condition, such that the passage of the ball retrieving device, and the lie of the ball on the ground may be disadvantageous for ball retrieval.
The present invention provides a method of picking up golf balls from the ground, including the steps of positioning arcuately discontinuous ball entraining means in close proximity to the ground, moving the entraining means against a golf ball to entrain the ball therewith, rotating the entraining means to raise the ball above the ground, and releasing the ball into an elevated receptacle.
The present invention further provides a low cost durable apparatus possessed of high retrieval efficiency.
An embodiment of the present invention provides peripherally discontinuous rotatable ball transfer or entrainment means to provide an arcuate path of transfer upwards from the ground; pivot means to secure the transfer means for passage over the ground in ball entraining relation therewith, and receiver means mounted above the ground in ball receiving relation with the transfer means to receive golf balls therefrom.
A further characteristic of one embodiment resides in a ball transfer means including a cylinder having a plurality of resilient peg means mounted in symmetrical spaced relation extending outwardly from the surface thereof, the peg means having enlarged spherical head portions to retain golf balls impressed therebetween, and a plurality of finger means extending between rows of the pegs to dislodge balls outwardly therefrom.
In an alternative embodiment the transfer means includes an arcuate deflector having a lower edge portion positioned to engage an underface of a grounded ball with the ball displacer means in radially spaced relation with the deflector to entrain a ball for motion upwardly therebetween for delivery to the receiver means.
Certain embodiments of the invention are described, reference being made to the accompanying drawings wherein FIG. 1 is a general view of one retrieving apparatus having a peg studded ball entraining cylinder;
FIG. 2 is a sectional side view of the FIG. I embodiment;
FIG. 3 is a similar view of a second embodiment having a brush type ball entrainer; and
FIG. 4 is a sectional side view of the FIG. 3 embodiment.
FIG. 5 is a view of a peg having a threaded portion in engagement with a threaded peg receiving means of the cylinder outer surface.
Referring to the embodiment illustrated in FIGS, 1 and 2, the retriever has a drum or rotor 12 having a plurality of rows of resilient pegs 14 in mutually spaced relation whereby the enlarged spherical head portions 16 combine to form a series of ball retaining receptacles. In the illustrated embodiment the rows of pegs 14 extend in axial alignment along the surface of the cylinder. whereby the cooperating pegs are in multiples of four. By staggering adjacent rows of pegs cooperating arrangements in threesomes are provided.
Also in FIG. I is illustrated an enlarged view ofa peg 14, showing the spherical head portion I6 and a base portion 18 having a means or groove 20 by means of which the peg is attached to the cylinder portion of the rotor 12, by insertion into holes or slots in the surface thereof. The use of a threaded nylon peg as shown in FIG. 5 has been found to be highly satisfactory. While possessing inherent resilience which may be selectively controlled to provide a desired degree of stiffness, the form of the peg also may be modified in cooperation with a resilient mounting in the drum face, to diminish local stresses when the peg descends endwise on a pro truding fixed object.
A pair of end plates 26 carried by the rotor 12 on journals 28 support a ball receptacle 30 having displacer plates 32, spaced along a peripheral edge thereof and extending between the adjacent rows of pegs, to displace balls entrained between the pegs for passage into the receptacle 30 see FIG. 2.
A handle 36, shown pivoted in a rearward direction serves to propel the apparatus, being normally latched in a forward extending direction by latch means, not shown.
Referring to the embodiment illustrated in FIGS. 3 and 4, a brush-like rotor 40 serves to entrain balls, in cooperation with a curved guide plate 42 mounted in end plates 46 to which a ball receptacle 50 is also attached, having a cover 52 extending thereover. The guide plate 42 is adjustably secured at 54, 56 whereby the degree of ground clearance of the toe portion 58 may be adjusted.
While the positioning of the respective embodiments is illustrated with relation to a handle, whereby the respective ball receptacles are maintained in the desired configuration, the use of auxiliary wheels spaced from the respective rotors, or the use of a pair of spaced rotors is contemplated, having an intermediate framework therebetween.
While the rotor 40 is illustrated as being of a brushlike structure, the use of axially extending ribs serving an equivalent function is contemplated.
What is claimed is:
l. A ball retriever comprising: a rotor having a pair of ends and a cylindrical outer surface, a plurality of peg receiving means in spaced row array about the cylindrical outer surface for receiving a peg in each said means, a plurality of resilient pegs, each of said pegs including an enlarged spherical head portion and a base portion, said base portion including means for mating with said peg receiving means, said base portion means comprising an endless groove and said receiving means comprising a slot for mating with said endless groove, a one of said pegs mounted in mating relation in a one of said peg receiving means with said enlarged spherical head portion extending outwardly of said cylindrical outer surface and forming a plurality of pockets, each of said pockets being adapted for trapping a ball of predetermined size in snug relation therein, a journal mounted centrally at each of said rotor ends, a pair of end plates, one of said end plates carried by each said journals, a ball receptacle carried by said end plates, said ball receptacle including a plurality of displacer plates spaced along a peripheral edge of said ball receptacle and a one of said displacer plates between each of the adjacent rows of pegs proximate the top excursion of said cylinder for directing trapped balls from within a pocket to said ball receptacle, and means for propelling said ball retriever secured to said end plates.
