A fourth pair of retention rods 27 and 28 (FIG. 7), substantially parallel to and spaced from the side rods 16 and 17, are affixed to the receptacle 1 (not shown in FIG. 7). The fourth pair of retention rods 27 and 28 limit the rotation of the hinges of the groups of hinges 23 and 24 in the opposite direction, indicated by an arrow 29 (FIG. 7) to a substantially horizontal plane.
The access arrangement of FIG. 7 operates in essentially the same manner as that of FIGS. 1 and 4, with the exception that an entering tennis ball (not shown in- FIG. 7) moves a corresponding hinge of each of the group of hinges 8 and 23 or a corresponding hinge of each of the group of hinges 9 and 24 and gains egress via the space provided between each set of corresponding hinges.
Bidirectionally extendable supports 31 and 32 (FIGS.- 1 and 2) are movably affixed to the receptacle 1. The supports 31 and 32 are securable in one position, shown in FIG. 1, for supporting the receptacle 1 at a predetermined distance above the ground to facilitate manual removal of tennis balls via the open top 2 (FIG. 3) of the receptacle. The supports 31 and 32 are securable in another position, shown in FIG. 2, for facilitating manually carrying of the receptacle 1 in suspension from said supports;
Each of the supports 31 and 32 comprises a substantially U-shaped member (FIG. 1), which preferably has substantially squared corners. Each of the U-shaped members 31 and 32 is rotatably mounted on a corresponding side 6 and 7, respectively, of the receptacle 1. Each of the members 31 and 32 is rotatable to a position in which it extends substantially full length beneath the receptacle 1, as shown in FIG. 1, and to another position in which it extends substantially full length above the receptacle 1, as shown in FIG. 2.
Each of the support members 31 and 32 may be rotatably mounted on a side rod of the receptacle in any suitable manner. Thus, each of the members 31 and 32 may be looped at its free ends around a corresponding side rod of the receptacle 1, as'shown in FIGS. 1 and 2. The uppermost and lowermost side rods on each side of the receptacle 1 are bent at their ends and turned inward toward each other, as shown in FIG. 1, to form securing parts to secure the U-shaped members 31 and 32 in each position. The uppermost side rods 33 and 34 thus form securing parts 35, 36 and 37, 38 (FIG. 1) to secure the U shaped members 31 and 32 in their upwardly extending positions, shown in FIG. 2. The lowermost'siderods 39 and 41 thus form securing parts 42, 43 and 44, 45 (FIG. 1) to secure the U-shaped members 31 and 32 in their downwardly extending positions, shown in FIG. 1.
To retrieve balls, the support members 31 and 32 are secured in their upwardly extending positions and are grasped manually by the user. Wherever he sees a ball, the user merely positions the receptacle 1 over the ball and permits said receptacle to settle over the ball. The ball enters the receptacle 1 via the space between the lowermost side rod 39 and a hinge of the group of.
hinges 8, or via the space between the lowermost side rod 41 and a hinge of the group of hinges 9. As soon as the ball enters the receptacle 1, the hinge which had moved to admit it returns to its normally substantially horizontal position and prevents the ball from falling out of the receptacle.v
To select a retrieved ball for play, the support members 31 and 32 are secured in their downwardly extending positions, so that they support the receptacle 1 at a convenient height above the ground. The user need merely reach into the receptacle and select a ball.
The tennis ball retriever is thus utilized without stooping or bending, and with full convenience, facility and comfort.
Thp tennis ball retriever of the invention may be utilized to retrieve otherballs than tennis balls, of course, or, for that matter, any suitably shaped objects such as, for example, fruit.
While the invention has been described by means of specific examples and in specific embodiments, we do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
