This invention relates to an improvement in basketball training apparatus and deals particularly with a support for suspending a ball similar in size to a basketball to assist in the training of basketball players.

Difiiculty is experienced in teaching basketball players to jump high in the air and to build coordination using both hands. In using the basketball for thispractice, diflicuity is experienced in throwing the ball into such a position that it is necessary for the player to jump high in the air to retrieve the ball. It is an object of the present invention to provide a ball corresponding in size to a basketball but suspended by a flexible cord or cable from a wall mounted arm. This arm is adjustable in position and accordingly may suspend the ball at an adjusted elevation so the players of different heights may be properly trained. The supporting arm is so suspended that it may be pulled down when properly grasped by the player, the arm returning to its original position when released.

A feature of the present invention resides in the provision of a ball supporting device which is scientifically designed to develop a basketball players ability in jumping and grabbing rebounds, to build cooperation in using both hands, as two hands are needed to pull the ball down, and to strengthen the forearms, wrists and hands. Through the use of the apparatus, coaches have reported that players have learned to jump 2 or 3 inches higher due to regular training with the apparatus.

A feature of the present invention resides in the provision of an apparatus including a pivotally supported arm which is mounted for pivotal movement in a substantially vertical plane and resilient means normally urging the arm to a predetermined elevation. A check valve is provided for cushioning the pivotal movement of the arm and to cushion the return movement of the arm to its starting position.

A further feature of the present invention resides in the provision of a device of the class described in which the ball simulating a basketball is mounted on one end of a flexible cord or cable and in which the cable extends through a hollow arm, the other end of the cable extending downwardly from the Wall mounting for anchorage. By pulling on this end of the cable, the elevation of the ball may be increased so that the ball may be anchored at any height and still may be pulled downwardly by the player due to the spring support of the arms.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims: 1

The basketball training apparatus is illustrated in general by the numeral A. The apparatus includes an arm which is designated in general by the numeral 10 and a wall mounting which is indicated in general by the numeral 11.

In the arrangement illustrated in FIGURE 1, the wall mounting 11 is shown as being attached to a pair of supporting members such as 2 x 4s or the like which are secured in vertical parallel relation to the wall surface by bolts such as 12 and 13 or other suitable anchoring means. The wall mounting includes a pair or" spaced parallel angle irons 14 having coplanar flanges 15 which are apertured as indicated at 16 for the accommodation of mounting bolts which are not shown in the drawings. A pair of generally U-shaped supports 17 are secured to the flanges 15 of the angle irons 14 to project forwardly therefrom. The tubular member 17 includes parallel ends 19 and 20 which are welded or otherwise secured to the flanges 15 as well as to the right angular flanges 21 of the angle members. The vertical intermediate portions 22 of the U-shaped members 17 extend in parallel spaced relation forwardly of the angle irons. These intermediate portions 22 of the tubular supports are connected by a fixed cross brace 23 and a detachable cross brace 24, the member 23 of which is of tubular form. The cross brace 23 is secured to the portion 22 of the support 17 by welding or other suitable means. The lower cross brace 24 may comprise a solid rod having axial threaded sockets 2-5 and 26 in its opposite ends. Bolts 27 extend through the vertical portions 22 of the supports 17 and extend into the sockets 25 for securing the lower brace in place.

The cross brace 24 is preferably provided with a collar or sleeve 29 which is rotatably supported on the cross member intermediate its ends. The collar 29 is held in place by spacing sleeves 30 which encircle the cross member 24 between the sleeve 29 and the support members 22. The arm 10 of the apparatus is secured to this sleeve 29 as will be described.

The arm 10 includes an upper arm member 31 of tubular form which is bent at its ends to provide a forward downturned end 32 illustrated in FIGURE 1 of the drawings and a rear downturned end 33 indicated in FIGURE 6 of the drawings. The downturned ends of the arms 31 are preferably flared at their extremities as indicated at 34. The-downturned ends 32 and 33'are connected by a connecting brace 35 which extends parallel As indicated in FIGURE 3 of the drawings, the collar 29 forms a bearing and is welded at the juncture between the brace 35 and the downturned end 33 of the arm;

31. As indicated also in this figure, a plate 37 is welded orv otherwise secured on a plane at right angles to 'the plane of the arm 31 and brace 35. The plate 37 is widened at its upper end to provide opposed shoulders 39 on opposite sides of the brace 10. As indicated in FIGURES 6 and 7 of the drawings, plates 40 are secured to the angle irons 14 to extend angularly with re spect to the anchoring flanges 15, the plates as incliningforwardly and downwardly as shown in FIGURE 6. Torsionsprings 41 encircle the sleeves 30 and are provided with ends extending in a tangential direction. One

3 end 42 of each spring 41 is engaged in a notch 43 in the free end of the corresponding plate 49 while the other end 44 of the springs are engaged with the shoulders 39 of the plate 37.

The springs 41 are so constructed as to normally hold the arm 10 at a forwardly and upwardly inclined angle. The wall mounting 11 is positioned high enough from the floor so that the free end of the arm 10 will never be drawn downwardly far enough to interfere with the players.

As is also indicated in FIGURE 3 of the drawings, a pair of straps 45 are welded in opposed relation to the arm 31 and brace 35, the straps 45 being provided with upwardly and outwardly diverging portions 4-6 connecting the body of the straps with parallel opposed ends 47 having aligned apertures 49 extending therethrough. An air check cylinder 50 is provided with a transverse hearing sleeve 51 at its end. A pin 52 extends through the apertures 49 in the ends 47 of the straps 45 and through the bearing sleeve 51 to pivotally connect the end of the cylinder 50 to the bracket straps.

As indicated in FIGURE 8 of the drawings, a U-shaped bracket 53 is welded or otherwise secured to the tubular cross member 23. A piston 54 within the cylinder 50 is provided with a piston rod 55 extending from the end of the cylinder 50 opposite that supporting the bearing sleeve 51. A pivot pin 56 is illustrated in FIGURE 8 extending through the parallel sides of the bracket 53 and through the piston rod 55 to secure the piston rod to this cross member.

A pair of elongated parallel cylinder slides 57 are illustrated in FIGURE 8 pivotally connected by pivot bolts 59 to angle brackets 60 which are also welded or otherwise secured to the cross member 23. These cylinder slides 57 extend on opposite sides of the piston 50 and, as is illustrated in FIGURE of the drawings are provided with elongated slots 61 through which the ends of the pin 52 may extend.

The piston 54 and cylinder 50 form an air check which retards the upward pivoting of the arm after it has been pulled downwardly. Due to the fact that the springs 41 require considerable force to flex, the springs would have a tendency to swing the arm 10 upwardly with considerable force after the ball was released. The check acts as a shock absorber or damper to reduce the speed of movement of the arm.

As is indicated in FIGURE 1 of the drawings, a flexible cord or cable 62 is anchored to a ball 63 which is usually made of metal and which is preferably approximately the weight of a basketball. The flexible cord extends upwardly through the downturned forward end 32. of the arm 31, through this arm 31 and its rear downturned end 33 to extend downwardly from the wall mounting. A clamp 64 is mounted on a wooden mounting 65 on the wall below the wall mounting 11. The cable 62 extends through the clamp 64 and may be held in any adjusted position thereby. Any other suitable means of anchoring the cable end may be employed, but it is desirable that the cable be readily adjustable so that the elevation of the ball may be varied to adapt to the height of various players. By pulling downwardly on the cable, the ball 63 may be raised and held in elevated position by the clamp. By releasing the clamp, the ball may be lowered to a desired extent. As a result, the elevation of the ball may be changed with little difficulty in a very small amount of time.

In accordance with the patent statutes, I have described the principles of construction and operation of my improvement in basketball training apparatus, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that changes may be made within the scope of the following claims with out departing from the spirit of my invention.
