Cl. 273-15 6 Claims ABSTRACT OF THE DISCLOSURE A device for use by basketball players in practicing the shooting of baskets over a defensive player and for use in practicing passing of the ball between offensive players, over or around a defensive player. The device includes a life-size figure of an adult male and rotatably driven arms, encased in a cushioning material, which project outwardly from the figure and which may be rotated in either direction. The apparatus is capable of use by a single player or a group of players.
BACKGROUND OF THE INVENTION This invention relates to a practice aid for use in the training of basketball players.
The prior art discloses backetball practice devices employed for training players in rebounding and for developing agility in players by the simultation movements of opposing players.
SUMMARY A primary object of the present invention is to provide a. novel apparatus for use by a single player or a group of players in practicing the shooting of baskets or the passing of a basketball between offensive players, over and around the apparatus, which realistically simulates a defensive player.
More particularly, an object of the invention is to provide a mobile device which may be conveniently positioned in any desired location on a basketball court, and which includes an upstanding wall member constituting a substantially life-size silhouette of the body and head of an adult male and which has arms projecting outwardly therefrom which are rotatably driven to simulate the movements of the arms of a defensive player attempting to block a basketball shot or to prevent the passing of a basketball between offensive players.
A further object of the invention is to provide novel control means whereby the arms may be rotated at different speeds and in either direction for varying the amount of skill required in shooting or passing over or around the device.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a presently preferred embodiment thereof, and wherein:

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring more specifically to the drawings, the basketball practicing aid in its entirety is designated generally 10 and includes a substantially fiat base or platform 11 which is supported on caster wheels 12 which provide a mobile support for the device 10.
A Wall member 13 extends upwardly from the base 11 adjacent one side edge thereof and is secured to said base by angle members 14 and fastenings 15, as seen in FIG. 2. The wall 13 is disposed in an upright position and is of a size and shape to provide a life-size silhouette of the body and head of an adult male.
A cross-shaped support 16 is secured to the inner or rear side of the wall 13 by fastenings 17. A stub shaft 18 is fixed to and extends outwardly from the support 16 to provide a journal for a'hub 19 having a centrally disposed bore 20 through which the stub shaft 18 extends, and which is enlarged at its ends, as seen at 21, to accommodate anti-friction bearings 22 and 23 on which the hub 19 revolves. A shoulder 24 on the stub shaft 18 provides a stop for the bearing 22. The bearing 23 abuts against a shoulder washer 25 which is retained by a nut 26 which engages the threaded outer end 27 of the stub shaft 18. A spacer sleeve 28 is mounted on the stub shaft 18 and extends between the inner races of the bearings 22 and 23 for maintaining proper alignment therebetween. The bore 20 is of sufiicient diameter to provide clearance for the hub around the sleeve 28.
The hub 19 is provided with an annular outwardly opening slot 29 and has a plurality, preferably four, outwardly opening sockets 30 which intersect the slot 29 and which are equally spaced circumferentially about the hub. Each socket 30 accommodates an inner end of a spoke or stave 31. Headed screws 32 extend through the hub 19 across the slot 29 and engage threaded sockets 33 of the hub for drawing the peripheral hub portions 34 and 35, which are separated by the slot 29, toward one another for clamping the spokes 31 in the sockets 30. The hub 19 has a restricted inner end portion disposed remote from the support 16 which is provided with an annularv groove 36 to form a V-belt pulley 37 I The spokes 31 are formed of a tough, semi-rigid material, and the outer end of each spoke is secured in a socket 38 of a substantially flat oval-shaped disc 39 which simulates a human hand. Each spoke 31 is encased in a thick tubular sheath 40, between the hub 19 and member 39. The members 39 and 40 are formed of a soft cushioning material to prevent injury to the players in the event of contact therewith.
An angle member 41, FIG. 4, is secured on the base 11 by fastenings 42. A shelf 43 is connected by hinges 44 to the upturned wall or flange 45 of the bracket 41. The
hinges 44 are secured by fastenings 46 to the wall and shelf 43. The shelf 43 is thus mounted for vertical swinging movement relative to the bracket 41.
A gear casing 47 is supported on and secured to the shelf 43 by fastenings 48 and is connected to and supports a small series wound electric motor 49, the housing of which is formed integral with the gear casing 47, as best seen in FIG. 5.
A pinion 50 on the armature shaft of the motor 49 meshes with and drives a gear 51 which is journaled on a stub shaft 52 which is supported in an inwardly opening socket 53 of the casing 47. The gear 51 has an integral pinion 54 which meshes with a gear 55 which is secured on a worm shaft 56 by a key 57 and set-screw 58. The ends of the shaft 56 are journaled in sockets 59 and 60 of the casing 47, and a ball 61 and thrust plate 62 takes up thrust on the end of the shaft 56 which engages the socket 59. End play on the shaft 56 is adjusted by a screw 63 and a ball 64 which is disposed between said screw and the other end of the shaft 56. The screw 63 is locked in different adjusted positions by a nut 65. A worm 66 on the shaft '56 meshes with a worm gear 67 which is secured on a shaft 68 by set-screw 68.
As seen in FIG. 4, the shaft 68 projects laterally from opposite sides of the casing 47 and has a V-belt pulley 69 fixed to one end thereof. An endless V-belt 70 is trained over the pulleys 37 and 69 for driving the hub 19 from the motor 49. One end of a pull spring 71 is secured to the shelf 43, remote from the hinges 44, and the other end of the spring is anchored to an eye fastening 72 which is secured in the base 11, for urging the shelf 43 to swing downwardly for maintaining a desired tension on the belt 70.
As seen in FIG. 2, a weight 73 is secured on the base 11, remote from the wall 13, for counterbalancing the weight of said wall and of the parts supported thereby. A housing 74 is mounted on the base 11 and encloses the weight 73, bracket 41, shelf 43, brackets 14, and the parts supported by said shelf. The housing 74 is secured to the inner or rear side of the wall 13 by fastenings 75. A belt guard 76 extends upwardly from a part of the housing 74 for enclosing a part of the belt 70, not enclosed by said housing, and for additionally enclosing the belt pulley 37, as seen in FIGS. 2 and 6. The upper part of the belt guard 76 is secured to the stub shaft 18 by a nut 77.
An electrical control unit 78 is shown mounted on the belt guard 76 and includes a speed control knob 79 which controls a contact 80 of a potentiometer 81, FIG. 8. The electrical control also includes two silicon rectifiers 82, tryac 83, and condenser 84.
An electric cord leading from the control unit 78 has a three prong electric plug for engagement in a 110 volt, 60 cycle alternating current outlet, not shown, from which current is supplied through the prong 87 of the plug 86 and through the conductor 88, which contains a fuse 89, to and through the control mechanism 78 to the conductor 90. The contact 80, controlled by the knob 79, provides a means for manually controlling the crest of the wave of the 60 cycle alternating current to change the speed of the reversible motor .49 which drives the belt pulley 69. Current is supplied through the conductor to the terminal 91, and through a field winding 92 of the motor 49 to the terminal 93. A conductor 94 leads from the terminal 93 to a contact 95 of a double pole double throw switch 96. When switch 96 is thrown to connect the contacts 95 and 98 and the contatcs 99 and 100, current will flow from contact 95 through conductor 97 to the contact 98 and through a conductor 101 to a terminal 102. The current will flow from the terminal 102 through the armature winding 103 of the motor 49 to the terminal 104 and from said terminal through a conductor 105 to the contact 99. Current will flow from contact 99 through the conductor 97 to contact and then through conductor 106 to a second prong 107 of the plug 86 for causing the motor 49 to drive the pulley 69 in one direction for re- 4 volving the hub 19 and the arms 31, 39, 40 in one direction and at a speed as controlled by the knob 79.
When the switch 96 is reversed so that the contact 95 is connected to contact 108 and contact 100 to contact 109, the current after passing through the field winding 92 and terminal 93 to contact 95 will pass through conductor 97 to contact 108 and then through a part of the conductor to the terminal 104. From terminal 104 current will flow in the opposite direction through the armature winding 103 to terminal 102 and then through conductor 101 to contact 109. Current will flow from contact 109 through conductor 97 to contact 100 and then through conductor 106 to the prong 107 for causing the motor 49 to be driven in the opposite direction for revolving the hub and arms in the other direction. The third prong 110 is suitably grounded at 111. An electricc'able 112, FIG. 7, connects the control unit 78 to the motor 49. It will be understood that the control unit could be mounted at a point remote from the remainder of the practicing aid.10. The arms 31, 40, 39 revolve between the wall 13 and the .belt guard, and behind said wall to realistically simulate arm movements of a defensive player so that a practicing player must shoot over said revolving arms or must pass over or around the arms to another player.
The shelf 43 is urged to swing downwardly by the weight of the motor 49, the gear casing 47 and parts contained therein and by the spring 71 to maintain tension on the belt 70 for driving the hub 19. However, if one of the arms 31, 39, 40 strikes a player or other obstruction, the belt 70 will slip relative to the pulley 37 so that rotation of the hub and arms will immediately cease to prevent injury to the player or to any part of the practicing aid 10.
Various modifications and changes are contemplated and may obviously be resorted to without departing from the function or scope of the invention as hereinafter defined by the appended claims.
