The present invention relates to a collapsible basketball return device for use in conjunction with a conventional basketball goal.
Like all sports, basketball requires many types of practice exercises. One such exercise is shooting baskets from a particular location on the floor, especially practicing free-throws from the free-throw line. Typically such practice involves the person shooting the baskets and one or more other persons to return balls to the shooter.
It would be very desirable to have a device that would automatically return balls to the shooter to free up other personnel for other purposes and to allow the shooter to practice by himself or herself.
It is an object of the present invention to provide a device for automatically returning basketballs shot at a basketball goal to the shooter.
It is a further object of the present invention to provide a device for automatically returning basketballs that is easily collapsible for storage and easily erected for use.
The collapsible basketball return device of the present invention includes pairs of front and rear vertical telescoping posts having tubular lower, central and upper portions. A pair of lower and upper horizontal telescoping side support arms extend between a lower portion of each of the front and rear posts. A pair of lower and upper horizontal telescoping end support arms extend between a lower portion of each of the front posts and between a lower portion of each of the rear posts, respectively.
A net is suspended from the telescoping posts and slopes toward the front of the device. The net is open at its top and is attached to a discharge chute at its bottom. The discharge chute is attached to the front telescoping posts by telescoping and rotatable support arms.
The basketball return device 10 of the present invention has a framework that includes: two vertical telescoping front posts 20 and two vertical telescoping rear posts 20′, respectively; two horizontal telescoping upper side support arms 30, respectively; two horizontal telescoping lower side support arms 30′, respectively; upper and lower horizontal telescoping front end support arms 40 and 40′, respectively; and upper and lower horizontal telescoping rear end support arms 140 and 140′, respectively.
The four vertical telescoping posts 20 and 20′ are identical in construction. One such post 20 is illustrated in
The diameter of upper portion 23 is smaller than the diameter of central portion 22, and upper portion 23 is adapted to be telescopingly received within central portion 22. Similarly, the diameter of central portion 22 is smaller than the diameter of lower portion 21, and central portion 22 is adapted to be telescopingly received within lower portion 21.
In the fully extended position of telescoping posts 20 and 20′ (substantially as shown in
Pipe couplers 24, 24′, 25 and 25′ are identical in configuration and are non-rotatably attached to upper and lower portions of bottom leg portions 21, 21′, as shown. The horizontal arms of couplers 24 and 24′ are adapted to receive one end of side support arms 30 and the lower horizontal arms of couplers 25, 25′ are adapted to receive one end of end support arms 30′, respectively.
Caster wheels 29 and 29′ are attached to the lower ends of bottom leg portions 21 and 21′, respectively, to make the device more mobile, particularly during movement into storage.
All four horizontal telescoping side support arms 30 and 30′ are identical in construction, the upper right support arm 30 being shown in
All four horizontal telescoping front and rear support arms 40, 40′, 140 and 140′ are similar in configuration to side support arms 30 and 30′, their fully extended length being shorter.
Pipe couplers 124 and 124′ located adjacent to pipe couplers 24, 24′, 25 and 25′, and are rotatable about bottom leg portion 21 and 21′, respectively. The horizontal arms of couplers 124 and 124′ are adapted to receive one end of front and rear support arms 40, 40′, 140 and 140′.
Eyebolts 26 and 26′ are attached to the outer end of upper portions 23 and 23′ of each of the four vertical posts 20 and 20′, respectively. A continuous cord 50, such as a bungee cord, extends between both front and rear posts 20 and 20′, through eyebolts 26 and 26′, down at least a portion of upper portions 23 and 23′ of posts 20 and 20′, through unattached (floating) rings 27 and 27′, and between rear posts 20′ and between front posts 20.
A net 51 includes net side portions 52 and 54 which are attached to, and extend downwardly from, that portion of cord 50 extending between front and rear posts 20 and 20′.
A generally triangular-shaped rear end net portion 56 is attached to, and extends downwardly from, that portion of cord 50 extending between rear posts 20′. The sides of rear end net portion 56 are attached to or integral with side net portions 52 and 54, as best seen in
A front end net portion 58 has an upper edge 158 which is attached to and extends downwardly from that portion of cord 50 extending between front posts 20, with the sides thereof being attached to or integral with side net portions 52 and 54 in a manner identical to rear end net portion 56. However, the upper edge 158 of front end net portion 58 is lower than the upper edge 156 of rear end net portion 56 in order to not interfere with the trajectory of basketballs shot at the basket.
Side net portions 52 and 54, rear end net portion 56, and front end net portion 58 form a tunnel-like configuration at the lower front end of return device 10.
The tunnel-like configuration formed by side net portions 52,54 and rear and front net portions 56 and 58 is attached at its outer end to a hollow basketball discharge chute 60. Discharge chute 60 has an inside diameter larger than the diameter of a basketball.
Details of discharge chute 60 and left and right chute support arms 70 and 70′ are shown in
Discharge chute 60 has an entrance end 62 and an exit or discharge end 64. A rim 66 encircles the entrance end 62, and a cord 68 encircles chute 60 adjacent rim 66. The netting adjacent discharge chute 60 is attached to cord 68.
Discharge chute 60 is supported by two identical left and right telescoping chute support arms 70 and 70′. Left and right chute support arms 70 and 70′ include a tubular inner portion 71 and 71′, respectively, a tubular middle portion 72 and 72′, respectively, a tubular outer portion 73 and 73′, respectively, an elbow 74 and 74′ attached to the outer ends of outer arm portions 73 and 73′, respectively, and a tubular hand member 75. Tubular hand member 75 passes through loosely fitting straps 76 and 76′ attached to the outer surface of discharge chute 60, as best seen in
Chute support arms 70 and 71 can be telescoped to an extended position, as shown in
Left and right chute support arms 70 and 71 are attached to left and right front posts 20 by means of left and right elbows 80 and 80′. Left and right elbows 80 and 80′ are adapted to swivel around tubular base members 21.
In the preceding description the netting of basketball return device 10 is configured to return basketballs shot essentially while facing the basket, such as throw practice, where the rear net portion 56 is located adjacent the backboard. The return device 10 can be configured to allow practicing shots at side angles. Such other configurations can be effected by having portions of netting on the right and left sides that can be folded up and down so that either the right or left sides can be placed closer to the backboard. In such a configuration the rear net would have a fold-up and fold-down portion also.
In use, the rear end of basketball return device 10, in the fully erected position shown in
To collapse basketball return device 10 for storage, telescoping left and right chute support arms 70 and 71 are partially collapsed and discharge chute 60 rotated so that its discharge end 64 faces inwardly and its entrance end 62 faces outwardly, as shown in
Next the user collapses telescoping posts 20 and 20′ downwardly, collapses horizontal telescoping side support arms 30 and 30′ inwardly, and pushes the front and rear end posts 20 and 20′ towards each other to fully collapse the basketball return device 10.
It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments of this invention without departing from the underlying principles thereof. The scope of the present invention should, therefore, be determined only by the following claims.
This application claims the benefit of U.S. Provisional Application No. 60/553,422, filed Mar. 12, 2004.
