Abstract
A batting practice stand has a length-adjustable post that has a ball-receiving cone at one end and L-shaped slots through its sidewall at its opposite end. By axially sliding the post into an opening of the base and rotating, the L-shaped slots engage a bar within the base opening to secure the post to the base. A compressible washer or stopper is provided in the bottom portion of the base to facilitate connection between L-shaped slots of the post and bar within the base. Legs extend outwardly from between flanges of the sidewall of the base. Between the flanges, the base defines socket openings that receive curved detent buttons extending from the proximal ends of each of the legs. Pins extend across the flanges and through the legs, and are engaged by slots defined in the curved detent buttons. The legs are rotatably moved from a storage position aligned with the legs substantially parallel to one another to a stand support position with the legs at angles to one another. The pins define the axis of rotation for the legs. Springs urge the curved detent buttons in a direction outwardly of the legs to keep the curved detent buttons within the socket openings in the base. Double gaskets at the connections between the telescoping post segments permit easy extension of the telescoping post segments, while resisting closing.

(26) Referring to the drawings in detail, FIG. 1 shows a batting practice stand 10 with a post 12 removably joined to a base 60. The stand 10 has a telescoping post 12 with a top post segment 14 that is received within a mid post segment 16 that is received within a bottom post segment 18. A cone 50 is joined by its distal end to the top of the top portion 14 of the post of the assembled batting practice stand 10. The cone 50 preferably is a rolled polymer or rubber and defines an opening 52 at its top end to receive a baseball 120 or softball (see, e.g., FIG. 7) placed thereon that is to be struck by a bat swung by a player. The cone 50 is flexible and will bend and recover upon being struck by the bat.
(27) As shown in FIGS. 1 and 2, the post is a three-part telescoping post, with the top or distal portion 14 slidably engagable within a middle portion 16 that is in turn slidably engagable within a bottom or proximal portion 18. The telescoping slidable movement of the post 12 enables post height to be adjusted within a range of about 20 inches to about 32 inches in one embodiment. Compare FIG. 1 and FIG. 7. The post 12 may be constructed of metal tubing of different diameters, such as steel or galvanized steel or aluminum, or may be constructed of a composite material, such as fiberglass. In one embodiment, the topmost post segment 14 is formed of solid fiberglass, and the middle post segment 16 and bottom post segment 18 are formed of hollow metal tubes of different diameters. Preferably, some or all of the post segments 14, 16, 18 are coated with a polymeric coating or paint.
(28) Cross-sections of the telescoping post 12 and sections of the telescoping post are shown in FIGS. 13-16. As shown in FIG. 15, the topmost post segment 14 is slidably joined to the middle post segment 16. As shown in FIGS. 14 and 16, the middle post segment 16 is slidably joined to the bottom post segment 18.
(29) In FIGS. 13, 15 and 19 the topmost post segment 14 is a solid rod, such as a fiberglass rod, which has a hollowed proximal end portion 15 into which a fastener 30, such as a screw or carriage bolt, is engaged. A gasket 36 inside the middle post segment is held by a c-shaped clip 38 fitted in a groove of the middle post segment 16. The gasket 36 surrounds the bottom portion of the topmost post segment 14. A sleeve fitting 23 abuts the gasket 36. A thimble shaped flanged gasket 34 abuts the fitting 23. The gasket 36 slidably engages the outer wall of the topmost post segment 14. The thimble-shaped flanged gasket 34 that is joined to the topmost post segment 14 slides within the middle post segment 16. A flanged gasket 25 seats within the recess opening of the thimble-shaped flanged gasket 34.
(30) In FIGS. 14 and 16 the middle post segment 16 is movably joined to the bottom post segment 18. The middle post segment 16 has a threaded proximal end 17 adapted to engaged with a threaded insert 21 and the threaded insert engages with a fastener 31. The fastener 31 secures a thimble-shaped gasket 34a with a flanged gasket 25a thereon to the proximal end of the middle post segment 16. A gasket 48 is held within the distal end of the bottom post segment 18 by a c-shaped clip 38a held within a groove in the bottom post segment 18. The double gasket comprised of gasket 34a and gasket 25a enables easier lengthening of the post 12 by slidably pulling the middle post segment 16 in a direction outwardly from the bottom post segment 18. The double gasket (e.g., 25a, 34a) poses greater resistance to shortening the length of the post 12 by frictional engagement of the double gasket (25a, 34a) to the inner wall of the bottom post segment 18.
(31) Referring to FIGS. 4 and 5, the proximal end 20 of the post is formed as a hollow cylinder that has two L-shaped slots 26, 28 formed at opposite sides of the sidewall of proximal end 20 of the post 12. The L-shaped slots 26, 28 have a straight that is aligned generally parallel with the central axis of the post and a straight that is generally perpendicular to the central axis of the post. A washer or stopper 40, such as a silicone washer, is placed inside the post 12 at or near its proximal end 20.
(32) As shown in FIGS. 2 and 4, the base 60 defines an opening 62 to receive the proximal end 20 of the post 12. Within the opening 62, a bar 64 extends across. The two L-shaped slots 26, 28 of the post 12 are adapted to engage the bar 64 to secure the post 12 to the base 60. First, the proximal end 20 of the post 12 is inserted into the central opening 62 of the base 60 so that the straights of the L-shaped slots 26, 28 that are axially aligned with the post axis receive the bar 64. Then, the proximal end 20 of the post 12 is rotated in a first direction (either clockwise or counter-clockwise depending upon the orientation of the L-shaped slots) so that the straights of the L-shaped slots 26, 28 that are generally perpendicular to the axis of the post 12 receive the bar 64. In the embodiment shown in FIG. 4, the post 12 is rotated clockwise for the slots 26, 28 to engage the bar 64. The post 12 may be removed from the base 60 by pushing down and rotating the proximal end of the post in the opposite direction (either counter-clockwise or clockwise) to release the L-shaped slots 26, 28 from the bar 64 and then pulling the proximal end 20 of the post 12 out of the base opening 62. See FIG. 2.
(33) The straights of the L-shaped slots terminate in cut outs 27a, 27b configured to receive the bar 64. The washer or stopper 40 inside the proximal end 20 of the post 12 facilitates a gripping connection between the post 12 and the bar 64 of the base 60. When the proximal portion 20 of the telescoping post or upright is inserted into the flange bushing of the base with the horizontal bar 64 in it and rotated, the washer or stopper 40 pushes down against the horizontal bar 64. When the bar 64 reaches the end of the channel, it is pushed down into the deeper recesses or cut outs 27a, 27b in the straights of the L-shaped slots and clicks into place, seating the bar 64 into the cut outs 27a, 27b.
(34) The legs 80, 82, 84 with feet 90, 92, 94 of the embodiment shown in FIGS. 1-6 form a tripod and extend outwardly away from the base 60 to support the batting practice stand 10 in upright position. The legs 80, 82, 84 may also be retracted to a storage position when the batting practice stand is not in use. See FIG. 3. Surfaces near the proximal ends of the legs 80, 82, 84 may be covered by protective sleeves 81, 83, 85, such as polymeric or rubber sleeves.
(35) Referring now in particular detail to FIGS. 3 and 6, pairs of flanges 66a, 66b, 68a, 68b, 70a, 70b extend outwardly from the sidewall of the base 60. Between the flanges, the base 60 defines curved sockets 78, 79. The curved sockets 78, 79 are shaped to receive curved detent buttons 100 (or bearings) that extend from the proximal ends of the legs 80, 82, 84. When the batting practice stand 10 is in the upright position, each socket 79 receives one curved detent button 100. The socket 79 is oriented in a direction at an angle to the opening of socket 78. A pin 72 extends across the space opening between each pair of flanges, e.g., 66a, 66b. Each pin 72 is inserted through the sidewalls of the proximal end of a respective leg, and through a slot 110 formed in the curved detent button 100 of a respective leg. The curved detent button 100 is slidably movable in respect of the pin 72. A compression spring (not shown in FIGS. 1-6, see 112 in FIG. 22) held within the proximal end of the leg, e.g., 80 (See FIG. 6) urges the curved detent button 100 in a directly outwardly of the proximal end of the leg. The pin 72 defines the axis of rotation for the leg joined to such pin 72.
(36) The operation of the folding legs is described with reference to one leg 80 as shown in FIG. 6. Due to the semispherical curve of the outer surface of the curved detent button 100, such button 100 seats within a respective socket 79 of the base 60, and is moveable in relation thereto. The spring force of the compression spring associated with the curved detent button 100 may be overcome to push the curved detent button 100 further into the proximal end of the leg 80 to permit the leg 80 to rotate from a first position supporting the batting practice stand in upright position (such as shown in FIG. 1) with the leg axes at angles to one another, to a second or storage position wherein the legs 80, 82, 84 are joined to the base 60 with their axes generally parallel to one another (such as shown in FIG. 3). When the legs are moved to the storage position, each curved detent button 100 moves from the respective socket 79 to the other respective socket 78. The outer surface of the button 100 slides in contact with the socket surfaces during rotating movement of the leg 80 from the first to the second position.
(37) The spring preferably is a conical spring or a conical coil spring.
(38) The base 60, particularly the flanges 66a, 66b, 68a, 68b, 70a, 70b, preferably is formed of metal, such as steel, galvanized steel or aluminum. The top opening 62 of the base 60 may be formed as a separate tubular socket that is attachable to the base 60. The sockets 78 of the base 60 may be separate inserts fitted into space between the flanges 66a, 66b, 68a, 68b, 70a, 70b. The sockets 78 may be formed of silicone or plastic or polymer.
(39) Referring next to the embodiment shown in FIGS. 7 to 18, FIG. 7 shows a batting practice stand 10 with a post 12 removably joined to a base 60. The stand 10 has a telescoping post 12 with a cone 50 joined at its distal end 58 at the top of the assembled batting practice stand 10. See FIGS. 13, 17 and 18. The cone 50 preferably is a molded polymer or rubber and defines an opening 52 at its top end to receive a baseball 120 or softball. The cone 50 further defines hand grip recesses 54 in its outer surface. The cone 50 is flexible and will bend and recover upon being struck by a bat.
(40) As shown in FIGS. 13 and 18, the post 12 is a three-part telescoping post, with the top or distal portion 14 slidably engagable within a middle portion 16 that is in turn slidably engagable within a bottom or proximal portion 18. The telescoping slidable movement of the post 12 enables post height of this embodiment to be adjusted within a range of about 20 inches to about 32 inches. The post 12 may be constructed of metal, such as steel or galvanized steel or aluminum, or may be constructed of a composite material, such as fiberglass. The post segments 14, 16, 18 may be hollow tubes or cylinders with hollow portions. Preferably, some or all of the post 12, particularly the external surfaces of the post segments 14, 16, 18, is coated with a polymeric coating or paint.
(41) Referring to FIG. 19, in one preferred embodiment the topmost post segment 14 is solid fiberglass. The bottom end of the topmost post segment 14 defines a threaded opening 15 configured to receive a threaded cylindrical pin or fitting 21 and to be secured by a fastener 30, such as a carriage bolt. A double gasket comprising a thimble-shaped gasket 34 with a recessed middle portion and a flanged gasket 25 to seat therein. The flanged gasket 25 may have an angled outer face. The thimble-shaped gasket 34 and flanged gasket 25 are urged against a cylindrical sleeve 23, a portion of which sleeve is engaged onto threaded cylindrical pin 21. A pin 22 is laterally inserted through the topmost post segment 14 to secure the cylindrical sleeve 23 and, optionally, the threaded cylindrical pin 21, to the topmost post segment 14. This pin 22 when inserted laterally strengthens the connection of the topmost post segment 14 to the cylindrical sleeve 23 and cylindrical pin 21 and the sliding elements of the topmost segment 14 of the telescoping post 12. The angled outer face of the flanged gasket 25 is directed such that it is somewhat easier with less frictional engagement when the topmost post segment 14 is raised or telescoped to increase the length of the post 12, but the angled face opposes downward telescoping movement of the topmost post segment 14 into the middle post segment 16 of the post 12 with greater frictional engagement between the topmost post segment 14 and the flanged gasket 25. This combination maintains the desired height of the telescoping post, keeping sufficient frictional engagement to deter downward sliding of the telescoping post segments. The preferred angle of the angled outer face may be in the range of from about 3 degrees to about 10 degrees to the central axis of the post 12.
(42) FIG. 21 shows the top portion of the middle post segment 16 of the telescoping post 12 of the preferred embodiment. The middle post segment 16 has an open end to receive a gasket 36 that is held by C-shaped retaining ring 18 seated in a groove formed inside the middle post segment, at or near the open end.
(43) FIG. 20 shows the bottom portion of the middle post segment 16 of the telescoping post 12 of the preferred embodiment. The middle post segment 16 has a hollow threaded end 17 with internal threads (not shown in FIG. 20) configured to engage with a fastener 31, such as a carriage bolt. Over the fastener 31 is threaded a double gasket comprised of a thimble-shaped gasket 34a with a recessed middle portion and a flanged gasket 25a to seat therein. The flanged gasket 25a may have an angled outer face. The fastener 31 secures the double gasket to the threaded end 17 of the middle post segment 16. The angled outer face of the flanged gasket 25a is directed such that it is somewhat easier with less frictional engagement when the middle post segment 16 is raised or telescoped to increase the length of the post 12, but the angled face opposes downward telescoping movement of the post segment 16 into the bottom segment 18 of the post 12 with greater frictional engagement between the middle post segment 16 and the flanged gasket 25a. This combination maintains the desired height of the telescoping post, keeping sufficient frictional engagement to deter downward sliding of the telescoping post segments. The preferred angle of the angled outer face may be in the range of from about 3 degrees to about 10 degrees to the central axis of the post 12.
(44) Referring to FIGS. 14 and 18, the proximal end 20 of the bottom segment 18 of the post 12 is formed as a hollow cylinder that has two L-shaped slots 26, 28 formed at opposite sides of the sidewall of proximal end 20 of the bottom segment 18 of the post 12. (See also FIG. 5) The L-shaped slots 26, 28 have a straight that is aligned generally parallel with the central axis of the post and a straight that is generally perpendicular to the central axis of the post. A cut out 27 configured to receive the bar 64 of the base 60 is formed in each straight. A washer or stopper 40, such as a silicone washer, is placed inside the bottom segment 18 of the post 12 at or near its proximal end 20, and near or adjacent to the L-shaped slots 26, 28. Alternatively, the washer or stopper 40 may be formed as a cylinder or hollow cylinder of rubber.
(45) The base 60 defines an opening 62 to receive the proximal end of the bottom segment 18 of the post 12. Within the opening 62, a bar extends across 64. See FIG. 10. The two L-shaped slots 26, 28 of the bottom segment 18 of the post 12 are adapted to engage the bar 64 to secure the post 12 to the base 60. First, the proximal end 20 of the bottom segment 18 of the post 12 is inserted into the opening 62 of the base 60 so that the straights of the L-shaped slots 26, 28 that are axially aligned with the central axis of the post receive the bar 64. Then, the proximal end 20 of the bottom segment 18 of the post 12 is rotated in a first direction so that the straights of the L-shaped slots 26, 28 that are generally perpendicular to the central axis of the post 12 receive the bar 64. The washer 40 urges the bar 64 into the cut outs 27 in the straights of the L-shaped slots 26, 28 to click the post 12 into place. The post 12 may be removed from the base 60 by pushing down and rotating the proximal end 20 of the bottom segment 18 of the post 12 in the opposite direction to release the L-shaped slots 26, 28 from the bar 64 and then pulling the proximal end 20 of the bottom segment 18 of the post 12 out of the base opening 62.
(46) The washer or stopper 40 is located at the top of the locking channel in the bottom segment 18 of the telescoping post 12 or upright. When this bottom segment 18 of the telescoping post 12 or upright is inserted into the flange bushing of the base 60 with the horizontal bar 64 in it and rotated, the washer or stopper 40, which preferably is a rubber piece, pushes down against the horizontal bar 64. When the bar 64 reaches the end of the L-shaped slots 26, 28, it is pushed down into a deeper recess 27 in the straights of the L-shaped slots and clicks into place.
(47) The legs 80, 82, 84 with feet 90, 92, 94 of the embodiment shown in FIGS. 7-18 form a tripod and extend outwardly away from the base 60 to support the batting practice stand 10 in upright position. The legs 80, 82, 84 may also be retracted to a storage position when the batting practice stand 10 is not in use. Compare FIG. 7 and FIG. 12.
(48) Referring now in particular detail to FIGS. 10 and 11, pairs of flanges 66a, 66b, 68a, 68b, 70a, 70b extend outwardly from the sidewall of the base 60. Between the flanges 66a, 66b, 68a, 68b, 70a, 70b, the base 60 defines curved sockets 78, 79. The curved sockets 78, 79 are shaped to receive curved detent buttons 100 that extend from the proximal ends of the legs 80, 82, 84. Each socket 79 receives one curved detent button 100 when the batting practice stand 10 is in the upright position with the legs 80, 82, 84 extended outwardly from the base 60 at angles to one another. Each socket 78 receives one curved detent button 100 when the batting practice stand 10 is in the storage position with the legs 80, 82, 84 positioned generally parallel to one another. A pin 72 extends across the space opening between each pair of flanges. Each pin is inserted through the sidewalls of the proximal end of a respective leg (see, e.g., FIG. 6), and through a slot 110 formed in the curved detent button of a respective leg. The curved detent button 100 is slidably movable in respect of the pin 72. A spring held within the proximal end of the leg urges the curved detent button 100 in a directly outwardly of the proximal end of the leg. The pin 72 defines the axis of rotation for the leg joined to such pin 72.
(49) Due to the semispherical curve of the outer surface of the curved detent button 100, such button seats within a respective first socket 79 of the base 60, and is moveable in relation thereto. The spring force of the spring associated with the curved detent button 100 may be overcome to push the curved detent button 100 further into the proximal end of the leg to permit the leg to rotate from a first position supporting the batting practice stand in upright position (such as shown in FIG. 7) with the leg axes at angles to one another, to a second or storage position wherein the legs are joined to the base with their axes generally parallel to one another. In the storage position, the curved detent button 100 is seated in a respective second socket 78 of the base 60. Each curved detent button 100 remains within its respective socket 78 or 79, and its outer surface slides in contact with the socket surfaces during rotating movement of the leg from the first or upright position to the second or storage position.
(50) The spring preferably is a conical spring or a conical coil spring.
(51) The base, particularly the flanges, preferably is formed of metal, such as steel, galvanized steel or aluminum. The top opening of the base may be formed as a separate tubular socket that is attachable to the base. The sockets 78, 79 of the base may be separate inserts fitted into space between the flanges. The sockets may be formed of silicone or plastic.
(52) It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this disclosure is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present disclosure as defined by the appended claims.
