Claims:
1. A tennis ball retriever comprising a yoke, a pair of spaced mounting discs rotatably attached to said yoke, a pair of spaced rings concentrically disposed about each of said discs, each of said pair of said rings being spaced from each other a distance less than the diameter of a tennis ball mounting means connecting said rings to said discs, a plurality of bars extending between and interconnecting said rings, said bars being inwardly spaced from the outer periphery of the outermost of each pair of spaced rings, said bars being spaced from each other less than the diameter of a tennis ball, one of said bars being removable, lugs on the outermost of said pairs of rings extending inwardly from the periphery thereof, said lugs having recesses therein, said one bar being hollow, detents movably disposed in said one bar, and springs in said bar urging said detents into said recesses.
Description:
BACKGROUND OF THE DISCLOSURE
1. Field of the Invention
This invention relates to a tennis ball retriever and more particularly to a device for retrieving tennis balls by rolling a mechanism along the ground. During the playing of tennis and especially during practice and teaching sessions, numerous tennis balls are used for demonstration and practice strokes. The picking up of these tennis balls by hand usually requires excessive bending, which will tire the player and make learning or instructing tennis more fatiguing and less rewarding.
2. DESCRIPTION OF THE PRIOR ART
Various devices have in the past been developed as tennis ball retrievers. In the Stap U.S. Pat. No. 3,371,950, there is disclosed a tennis ball retriever which requires the successive pressing down of the receptacle over the tennis balls. This has two great disadvantages, one of which is that the device still requires a stooping and bending operation. The second disadvantage is that the Stap device requires a variety of rods which are pressed over the ball and which in actual use generally through the tilting of the receptacle until an edge thereof strikes the tennis court causes the marring of the surface thereof to an undesired degree. Retrievers for various ball shaped objects such as shown in U.S. Pat. Nos. 3,485,398, 3,227,298 and 3,215,293 have also been devised but have likewise proved unsatisfactory because of the excessive weight of these devices as compared to the surface of a tennis court, which would cause marring of the surface of the court.
SUMMARY OF THE INVENTION
The present invention overcomes the disadvantages of the prior art devices by providing an extremely lightweight tennis ball retriever which is arranged to keep spaced bars through which the tennis balls are squeezed above the surface of the ground, with the only contact with the ground being by way of a pair of spaced rings. The construction of this invention features a yoke-shaped handle having small discs rotatably attached thereto which discs have spaced rings concentrically disposed thereabove and mounted thereon. A plurality of spaced bars are attached to the inner periphery of the rings so as to be spaced from the ground with one of the bars being removable.
It is therefore an object of the present invention to provide a tennis ball retriever that is light in weight and simple of construction, capable of being manufactured out of readily available materials and which is efficient in use.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this tennis ball retriever, a preferred embodiment of which has been shown in the accompanying drawing by way of example only, wherein:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the invention;
FIG. 2 is a side elevational view of the tennis ball retriever;
FIG. 3 is an enlarged front elevational view thereof;
FIG. 4 is an enlarged schematic view showing the manner in which a tennis ball is picked up;
FIG. 5 is an enlarged sectional detailed view showing the construction of the removable bar; and
FIG. 6 is a sectional detailed view looking in the direction of plane of line 6--6 in FIG. 5.
With continuing reference to the accompanying drawing wherein like reference numerals designate similar parts throughout various views, reference numeral 10 generally designates a tennis ball retriever constructed in accordance with the concept of the present invention. The tennis ball retriever 10 includes a handle 12 in the form of a yoke 14 having a rectangular extension 16 bolted as at 17 or otherwise secured thereto. The yoke includes a pair of parallel legs 18 and 20 which have a pair of discs 22 and 24 rotatably attached thereto as by stub shafts 26, 28 or the like. A pair of spaced rings 30 and 32 are provided and are rigidly connected to the discs 22 and 24 by radius rods 34 and 36 which have concentric rings 38, 40 and 42, 44 attached thereto. The rings 38, 40 are spaced from each other and from the ring 30 a distance less than the diameter of a tennis ball, and likewise the rings 42 and 44 are spaced from each other and from the ring 32 a distance less than the diameter of a tennis ball so that no tennis ball can pass therebetween.
A plurality of spaced bars 50 are welded to the inner surfaces of the rings 30 and 32 and extend therebetween. In this manner the bars 50, which can be best seen in FIG. 4, are spaced upwardly from the surface of the ground G when the tennis ball retriever is rolled along the ground. The bars 50 and 52 are spaced from each other a distance L which is slightly less than the diameter of a tennis ball T. The tennis ball T is slightly squeezed as the tennis ball retriever is passed along the ground and passes into the interior of the tennis ball retriever.
In order to permit access into the interior of the tennis ball retriever, a bar 60 is provided which is removable. In order to carry this out, two lugs 62 and 64 are provided which are welded inwardly of the rings 30 and 32 and which have recesses 66 and 68 therein. The bar 60 is hollow in construction and a pair of springs 70 are provided therein which press on detents 72 and 74 urging them into recesses 66 and 68. The bar 60 has slots 76 therein through which actuators 78 extend, which actuators when moved in the direction of arrow A to the position as shown in dotted lines in FIG. 5, will release the detents 72 and 74 from within the recesses 66 and 68 to thereby permit removal of the bar 60.
In use, the tennis ball retriever is rolled along the ground, picking up balls by squeezing them through the adjacent bars 50. When it is desired to remove the balls from the retriever, the bar 60 may be removed and all of the balls dumped into any convenient receptacle as desired.
A latitude of modification, substitution and change is intended in the foregoing disclosure, and in some instances some features of the invention will be employed without a corresponding use of other features.
