DETAILED DESCRIPTION OF THE INVENTION
Turning to FIG. 1, the ball retrieving apparatus A according to the present invention is shown when in a fully deployed position. The apparatus has a central shaft member 2 having a top end region 4 and bottom end region 6. As best shown in FIGS. 2, 3 and 4, a smooth, hard, convex end cap 7 is provided at the terminus of bottom end region 6. The end cap 7 is provided to resists wear against the bottom of the shaft member 2 during use of the device.
A pair of hand grips 8 is secured to the shaft member 2 along the top end 4 of shaft 2. As is apparent, the device A is operable without hand grips 8 and it is within the scope of the invention to provide other gripping members. For example, gripping regions may be integrally formed within the top end of the shaft member 2.
A pair of cooperating arm members 10 are connected at the bottom end 6 of shaft 2. Each of the arm members 10 has a first end 12 and second end 14.
A collapsible brace member 16 extends between the arm members 10 to maintain the arm members in a V-shaped open position during operation of the device. When in an open position, the arm members 10 in combination with the brace member 16 form a ball collection member having first and second regions for respectively gathering and collecting balls. Brace member 16 comprises a pair of hinged legs 18 and 20 adapted to be locked into an open and fixed position. One leg 18 of brace member 16 is pivotally secured (not shown) at its first end to the underside of one of the arm members 10 and at a location approximately two thirds of the way between the first end 12 and second end 14 of arm member 10. A second leg 20 of brace member 16 is pivotally secured (not shown) at its first end to the underside of the other of the arm members 10 and also at a location approximately two thirds of the way between the first end 12 and second end 14 of arm member 10.
As best shown in FIG. 1, a connection member 22 in the form of a wing nut with screw, interconnects brace legs 18 and 20 at their respective second ends. Other types of fasteners are within the scope of the present invention so long as they secure the brace member 16 in a fixed or deployed position as will be fully explained below. In the embodiment shown in FIG. 1, brace leg 20 includes a stop member 24 for limiting the range of motion of brace member 16 between its open and collapsed positions.
As is apparent, other collapsible brace members are within the scope of the present invention so long as, when deployed, it maintains the arm members 10 in an open position and it does not interfere with folding of the apparatus. For example, the arms of the brace member could extend telescopically or via pneumatic piston members.
The region between the shaft member 2, arm members 10 and brace member 16 forms an equilateral triangle when the device is fully deployed and as best shown in FIG. 1. As is apparent, the device will nevertheless function when the angle between any two sides is greater than or less than sixty degrees. In one embodiment, brace member 16 is positioned approximately thirteen inches from the hinge region identified as B in FIG. 1. That distance is preferred when the device is primarily used for collecting golf balls. When the device is primarily used for collecting tennis balls, the preferred distance between the brace member 16 and the hinge region B is about twenty five inches. Either distance will enable the device to function for collection of both golf and tennis balls. The preferred distances between the brace member and the hinge region provide a larger or smaller collection region 26.
Returning to FIG. 1, collection region 26 includes a two ply layer of nylon netting or mesh material 28 having a triangular shape and being secured to each of the arm members 10. It is within the scope of the invention to use a sheet material formed from a different material such as, for example, cloth or plastic. The area forward of the brace member 16 and between arm members 10 is a gathering region 30 that will be further described below.
A strap or length of cord 32 formed from nylon or another resilient material is secured to a side of the mesh material 28 adjacent brace member 16 and forms a loop 34 or lifting handle as best shown in FIG. 2. A pair of wheels or castors 36 is secured to the undersides of arm member 10 and at the first ends 12.
Turning to FIGS. 4 and 5, hinge region B is shown in greater detail. Arm members 10 are secured to shaft member 2 by a pair of grommet members 36, each of which extends through a separate one of the pair of arm members 10. An insert nut 38 is shown to extend through the shaft member 2. A post screw 40 having end caps 42 extends through the insert nut 38 and though each of the grommets 36. This arrangement allows the arm members 10 to pivot upwardly and downwardly relative to shaft member 2 and in a direction as indicated by arrows 44 of FIG. 1. The arrangement also allows the arm member 10 to pivot toward shaft member 2 and in a direction as indicated by arrows 46 of FIG. 2.
In a preferred embodiment, the length of the post screw 40 is about two and one quarter inches for a golf ball lifting device and two and a half inches for a tennis ball lifting device. It is within the scope of the present invention to provide other lengths for the post screw depending upon the nature of the balls to be collected.
Additional features include hook and loop connector strips 48 and 50, sold under the trademark VELCRO, which are provided on shaft member 2 and arm members 10 and as best shown in FIG. 1. These connectors maintain the device in a folded position as will be further explained below.
Turning to FIG. 3, the ball retrieving apparatus of the present invention is seen in a fully folded position. To unfold the device for use, the VELCRO strips 50 are separated from VELCRO strip 48 disposed on shaft member 2. This enables the arm members 10 to swing outwardly and away from shaft member 2 as best by arrows 46 in FIG. 2 and into a fully expanded position so that brace legs 18 and 20 can be interlocked together by rotating connection member or wing nut 22.
The fully expanded arm members 10 are then rotated downwardly in the direction of arrows 44 of FIG. 1 and into an operational position whereby the arm members 10 extend generally transverse to the longitudinal axis of shaft member 2.
As best shown in FIG. 6, a number of golf balls GB scattered along a surface may be collected by grasping the shaft 2 at hand grips 8 and wheeling the device so that the open faced gathering region 30 is moved adjacent the golf balls GB where they can be deposited within collection region 26 by brushing them in by hand, foot or using a tennis racquet of golf club.
After a number of balls have been accumulated within collecting region 26, the user grasps handles 34 and lifts the group of collected balls so that they may be carried to a separate location for deposit (not shown).
The present invention permits collection of about two dozen golf balls or three dozen tennis balls scattered along a surface. Collection is easily achieved as the device may be conveniently wheeled along the ground to the balls where they may be manually brushed into the collection region 26. After use, the device is easily returned to a folded position by loosening the brace connection member and swinging the arm members upwardly and against the shaft for securement by connectors 48 and 50.
While this invention has been described as having a preferred design, it is understood that it is capable of further modifications, and uses and/or adaptations following in general the principle of the invention and including such departures from the present disclosure as come within the known or customary practice in the art to which the invention pertains, and as may be applied to the central features hereinbefore set forth and within the scope of the invention.
