Definitions

• the present invention generally relates to a device with which players can practice their swings in baseball and their fielding in baseball and cricket.
• the ball/ball-like object which can be in either a static or dynamic mode, is attached to the sports device which can be used indoors or outdoors regardless of the surface to practice hitting; with the hitter being able to predict the trajectory the ball/ball-like object would have taken after being hit; and by the number of times the ball/ball-like object rotates, how powerful the swing was.
• the present invention can also be utilised in fielding practice where the ball/ball-like object sits freely on the sports device and is hit to a player who fields it.
• Prior art devices relating to baseball hitting devices where the ball is connected or attached to such devices can be generally divided into two groups.
• the commonality of the first group of such prior art devices is that the ball is suspended vertically by a combination of flexible and non-flexible means from a base.
• Some of the drawbacks of such prior arts are: (1) As the ball is suspended vertically by a combination of flexible or non-flexible means this requires the device itself to be large in dimension relative to the hitter; or the device must be quite heavy or staked to the surface or attached to an external structure. (2) If the batter swings but misses the ball, the flexible or non-flexible means used to suspend the ball is struck, falsely moving the ball.
• This group can be further sub-divided into three sub-groups: (1a) sub-group in which just before hitting, the ball is in a static mode in which virtually all such devices exist; (1b) sub-group in which just before hitting, the ball is in a dynamic mode in which there is a paucity of such devices; and (1c) sub-group in which just before hitting, the ball is in either a static or dynamic mode in which also there is a paucity of such devices.
• Typical prior art devices of the sub-group (1a) are found in U.S. Pat. Nos. 3,994,494 to Kelly; 4,966,367 to Oyarzabal; 6,099,419 to Incaudo et al; 6,296,582 to Minniear; 6,306,050 to Holder.
• Typical examples of prior art devices of the sub-groups (1b) and (1c) are virtually non-existent.
• the ball extends out to the hitter.
• This group can also be further sub-divided into three sub-groups: (2a) sub-group in which just before hitting, the ball is in a static mode in which virtually all such devices exist; (2b) sub-group in which just before hitting, the ball is in a dynamic mode in which there is a paucity of such devices; (2c) sub-group in which just before hitting, the ball is in either a static or dynamic mode in which there is also a paucity of such devices.
• Typical prior art devices of the sub-group (2a) are found in U.S. Pat. Nos. 1,962,087 to Cone; 5,618,039 to Tsai et al; 6,099,419 to Incaudo et al.
• Typical prior art devices of the sub-group (2b) and 92c) are virtually non-existent.
• Prior art devices relating to baseball hitting devices where the ball is not connected or attached to such devices can also be divided into two groups.
• the commonality of the first group of such devices is that they are pitching machines which project a ball to the player.
• Major disadvantages of such devices are: (1) They require electricity to operate. (2) They cannot be operated by just one person.
• This group can be further sub-divided into three sub-groups: (3a) sub-group in which just before hitting, the ball is in a static mode in which virtually no such devices exist; (3b) sub-group in which just before hitting, the ball is in a dynamic mode in which such virtually all such devices exist; and (3c) sub-group in which just before hitting, the ball is in a static or dynamic mode in which virtually no such devices exist.
• Typical prior art devices of sub-groups (3a) and (3c) are virtually non-existent.
• Typical prior art devices of sub-group (3b) are found in U.S. Pat. Nos. 4,197,827 to Floyd et al; 6,093,117 to Sherlock et al.
• This group can be further sub-divided into three groups: (4a) sub-group in which just before hitting, the ball is in a static mode in which virtually all such devices exist and are the traditional batting Tees; (4b) sub-group in which just before hitting, the ball is in a dynamic mode in which such virtually no such devices exist; (4b) sub-group in which just before hitting, the ball is in either a static or dynamic mode in which such virtually no such devices exist.
• Typical prior art devices of the sub-group (4a) are found in U.S. Pat. Nos. 6,884,185 to Udwin et al; 5,556,091 to Lin; 4,176,838 to Griffin.
• Typical prior art devices of sub-groups (4b) and (4c) are virtually non-existent.
• Prior art devices relating to baseball hitting devices where the ball is not connected or attached to such devices and from which a ball is projected to the player or the ball resides freely are also used to practice fielding in baseball. Examples of such prior art devices and their general disadvantages are discussed above.
• Major advantages of the present design over baseball prior art devices are: (1) It can function both as a hitting and a fielding device. (2) In hitting mode, the ball just before being struck can either be in a static or a dynamic mode. (3) The movement of the ball is constrained within a sphere which greatly enhances safety by defining the space needed to do hitting practice. (4) It increases the number of swings that can be taken in a given period of time. (5) For a set height, returns the ball to different positions after each hit. (6) Does not have to be anchored to a surface or require an external structure to be fixed to. (7) The ball is not hit in the same spot with every swing. (8) When the ball is hit, it is not the arm member that directly receives any stress.
• the objective of the present invention is to provide a device that can be used to practice hitting in baseball without the need for a net.
• Another objective of the present invention is to provide a device which can withstand the extreme forces applied when practicing hitting in baseball.
• Another objective of the present invention is to provide a device where any broken part can easily be replaced.
• Another objective of the present invention is to provide a device that can be used equally indoors and outdoors to practice hitting in baseball and fielding in baseball, with the device being portable and collapsible.
• Another objective of the present invention is to provide a device that can be used to practice hitting in baseball and fielding in baseball with the device capable of being used by both right hand and left handed hitters of all heights.
• Another objective of the present invention is to provide a device that can be used to practice hitting in baseball with the ball/ball-like object placed stationary at any one time among a plurality of positions.
• Another objective of the present invention is to provide a device that can be used to practice hitting in baseball with the ball/ball-like object placed at any one time among a plurality of positions and at each position, rotated counter clockwise into a right handed hitter or clockwise into a left handed hitter at speeds that vary from fast to slow, with the hitter either hitting or bunting the moving ball/ball-like object.
• Another objective of the present invention is to provide a device that can be used in baseball to practice hitting a curve ball.
• Another objective of the present invention is to provide a device that can be used in baseball to practice fielding by hitting a ball/ball-like object into free flight to players.
• the design of the present invention achieves these objectives by departing from prior art devices as follows.
• the way to absorb the stress imparted on the device when the ball/ball-like object is hit is to hang elastic members vertically from a base with the ball/ball-like object attached to the elastic members.
• the elastic members are in a substantially horizontal position as they are housed in an arm member which is mounted in a substantially horizontal position on a base in hitting practice mode.
• the arm member can rotate freely and completely the hitter in baseball can in effect ‘self-pitch’ when practice hitting.
• the ball/ball-like object can be in a plurality of positions prior to hitting in either a static or dynamic mode.
