Definitions

• a batting practice device that includes a spring arm carrying a ball and allowing the ball to be oscillated to present a moving target, the connection to the ball being separable when the ball is struck A cord secured to the ball limits its travel and permits retrieval.
• the spring arm is a resilient plastic tube releasably connected at one end to the ball and having its other end frictionally fitted into a vertical pole mounted in the ground PATENTEIJnnvsmsn 3,623,725
• This invention relates to a device for practicing baseball batting.
• the present invention provides an improved batting practice device in which the ball may be moving at the time it is hit. Moreover, the ball is attached to a cord for ready retrieval and to limit the distance it is driven.
• the device includes a vertical support that carries a resilient member at its upper end. The outer end of the resilient member is adapted to be attached to the ball.
• the resilient member and ball can be made to oscillate before the batter swings, so that the ball is moving and made more difficult to hit, and the batters eye is sharpened.
• the attachment to the ball is separable when the ball is struck.
• a cord is secured to the ball and to a stake, so that the flight of the ball is limited, allowing the device to be used in confined areas.
• the ball may be retrieved by the cord without moving from the locale of the practice device.
• the unit is of simple economical construction that stores compactly and is readily assembled or disassembled.
• An object of this invention is to provide an improved baseball batting practice device.
• Another object of this invention is to provide a batting practice device in which the ball may be made to present a moving target.
• a further object of this invention is to provide a batting practice device usable in confined areas and which does not require the presence of fielders to retrieve the ball.
• Yet another object of this invention is to provide a batting practice device of simple and economical construction, which is readily assembled and disassembled and which stores compactly.
• FIG. I is a perspective view of the batting practice device of this invention as it is used;
• FIG. 2 is an enlarged fragmentary sectional view taken along line 2-2 of FIG. 1, illustrating the attachment of the resilient support member to the upper end of the pole;
• FIG. 3 is an enlarged fragmentary elevational view, partially broken away, showing the attachment of the ball to the end of the resilient support.
• FIG. 4 is a view similar to FIG. 3 for a different type of attachment to the ball.
• the device of this invention includes a pole 10, to the upper end of which is secured a resilient member 11, the outer end of which removably connects to a baseball 12.
• the member 11 extends laterally away from the pole and is inclined downwardly at its outer end. This means that a baseball bat, moving generally in a horizontal direction, can strike the ball 12 without hitting the arm II that supports it.
• a length of cord 13 is connected to the baseball and also to a stake 14 that is driven into the ground.
• the member 11 is springy so that, with the weight of the ball 12 at its outer end, it is readily made to oscillate at the time the batter l5 wishes to attempt to strike the ball.
• the ball 12 will swing back and forth at the end of the member 11 as the member 11 flexes and swings somewhat as a pendulum. This presents a moving target to the batter, making it more difiicult to strike the ball.
• the practice becomes much more efi'ective, as the batter learns to improve his skill in striking a moving ball as he must when the game is played.
• the components of the practice device conveniently are of plastic, which makes them light in weight, easy to handle and low in cost.
• Suitable for the pole 10 is a rigid plastic tube of around eleven sixteenth of an inch outside diameter.
• a short length of a larger tube or pipe 17 is buried in the ground. This provides a socket into which the lower end of the pole may be inserted when the practice is to take place.
• the resilient member 11 also may be a plastic tube of springy characteristics, which may be secured to the upper end of the pole as shown in FIG. 2. As seen in this illustration, there is a sleeve 18 received in the upper end of the pole l0 and bonded to it. This provides a socket that receives the inner end of the member 11 with a press fit. Therefore, at the time of the batting practice, the member 1 l is forced into the sleeve 18 at the upper end of the pole 10, where it is held by the press fit and without auxiliary fastening means. The end of the tube 11 may be scarfed as shown to facilitate its entry into the sleeve 18.
• the ball 12 may be held to the outer end of the resilient tube 11 in the manner shown in FIG. 3.
• a member 19 that forms the attaching means.
• Particularly suitable for the member 19 is the type of element that ordinarily serves as the movable portion of a cabinet catch. These devices include a threaded shank 20 and a bulbous somewhat spherical outer portion 21.
• a driving slot 22 is included in the outer end of the portion 20, allowing the shank 20 to be screwed into the baseball 12.
• the bulbous portion 21 of the member 19 presents a rounded tapered part facing outwardly that easily enters the end of the tube 11.
• the maximum diameter of the portion 21 is greater than the inside diameter of the tube 11 so that it wedges into the end of the flexible tube 11, where it is held by friction. This provides the attachment for the ball to the member 11. At the same time, this attachment is readily separated when the ball is struck.
• a screw eye 24 is screwed into the baseball 12 to form the connection for the cord 13.
• the cord merely is tied to the screw eye 24 and also to the stake 14.
• the ball easily is attached to the flexible support 11 simply by forcing the bulbous portion 21 of the member 19 into the end of the tube that forms the member 11. Then the member 11 is caused to oscillate as a spring so that a moving target is presented to the batter 15.
• the bulbous portion 21 of the member 19 is pulled easily from the end of the tube forming the support 11 and driven away.
• the cord 13 limits the travel of the ball, so that the practice device may be used even in confined areas. Also, the cord 13 provides a means to pull the ball back for retrieval without the necessity of moving from the area of the practice device.
• the entire unit is disassembled simply by pulling the pole from the socket 17 and by removing the resilient arm 11 from the sleeve 18 at the upper end of the pole 10.
• the lightweight components store compactly.
• FIG. 4 An alternate arrangement for attaching the ball to the practice device is shown in FIG. 4.
• a magnet 25 is held frictionally by means of an outer sleeve 26 to the end of the flexible tubular arm 11.
• a second magnet 27, or alternatively a piece of magnetic material, is buried in the ball 12 and may be beneath the cover 28. Again, the ball will be held to the supporting device until such time as the ball is struck by the bat, after which the connection is readily severed.
• the arm 11 may be made of other materials, such as spring wire, but the plastic tube offers advantages in facilitating the attachment of the ball.
• a batting practice device comprising a pole adapted to be mounted in a vertical attitude
• said connecting means being separable in response to an impact on said ball
• said arm being a resilient plastic tube throughout the length thereof for allowing said ball to be oscillated while attached to said arm,
• said pole including a socket in the upper end thereof
• one end of said plastic tube being received in said socket with a press fit for thereby attaching said tube to said pole.
• said connecting means includes a member having a first portion connected to said ball and a second portion exteriorly of said ball, said second portion being tapered for entry into the distal end of said plastic tube and being dimensioned to wedge therein for providing said connection of said ball to said arm.
• a device as recited in claim 1 including in addition a tube and a supporting medium, said tube being received in said supporting medium with one end of said tube being substantially flush with a surface of said medium, one end of said pole extending into said tube, whereby said tube supports said pole in a vertical attitude.
• a batting practice device comprising a tube
• said tube being received in said medium with one end thereof substantially flush with said upper surface of said medium
• a cord means securing one end of said cord to said ball, and means anchoring the opposite end of said cord to said medium, whereby said cord allows retrieval of said ball and limits the travel thereof.
