Primary Examiner-Richard C Pinkham Assistant Examiner-Paul E Shapiro Attorney-Hood, Gust, Lundy & lrish ABSTRACT: A support for a basketball goal. A first support boom is connected at one end to a stationary overhead structure for pivotal movement about a generally horizontal axis between a lower use position and an upper storage position, the other end of the first boom being proportioned and designed to carry such a goal. The first boom carries a pair of roller stops intermediate its ends. A second support boom is connected at one end to the stationary structure for pivotal movement about a second axis and between a lower position and an upper position, the second axis being parallel to the pivot axis of the first boom. The second boom is bifurcated in its distal region to straddle the first boom, and its distal extremity is closed by a transverse member constituting a second stop means which, when the second boom is in its lower position, engages that surface of the first boom which is remote from the second axis to support the first boom in its use position. A cord and pulley system is provided to lift the first boom from its use position to its storage position, and the pair of stops coact with the second boom during such movement to lift the second boom also to its storage position. There is described, therefore, a support comprising a pair of interlocking booms, both of which are foldable between a lower use position and an upper storage position.

FORWARD FOLDING BASKETBALL BACKSTOP It is a primary object of my invention to provide support means for a basketball goal including a backboard and hoop, which means can be mounted on the superstructure of a gymnasium to be foldable between a lower, use position to an upper, storage position.

Another object of my invention is to provide such a support means comprising a main or first support boom, one end of which is to be pivotally connected to a support structure for pivotal movement about a generally horizontal axis and the other end of which is proportioned and designed to carry a backstop, the boom being foldable forwardly from its lower, use position to its upper, storage position. In its use position, this main support boom is inclined downwardly and forwardly at an angle of, for instance, approximately 60 relative to a horizontal plane, such as the playing floor of the gymnasium. I provide a second support boom which is to be pivotally connected to the superstructure at a point forwardly of the pivotal connection for the main boom so that, when the second boom is in its lower, use position, it is inclined downwardly and rearwardly. This second boom carries, at its distal end, a stop means which engages the main boom and holds it in its lower, use position. The main boom carries, intermediate its ends, stop means for engaging the second boom and holding it in its lower, use position. The main boom and second boom are arranged so that, when the main boom is lifted to its storage position, the main boom will lift the second boom to its storage position.

Other objects and features of the present invention will become apparent as this description progresses.

To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described, so long as the scope of the appended claims is not violated.

In the drawings:

FIG. 1 is a perspective view of my support means for a basketball goal;

FIG. 2 is an elevational view of the support means; and

FIG. 3 is a fragmentary sectional view, slightly enlarged, taken from FIG. 2 generally along the line 3-3.

Referring to the drawings, it will be seen that my support means, indicated generally by the reference numeral 10, comprises a first support boom 12 and a second support boom 14.

I prefer to construct the main support boom 12 by welding together a heavy steel tube 16, a steel channel member I8, a pair of gusset plates and a pair of steel pipes 22, 24. As illustrated in FIG. I, the upper end of the tube 16 is connected to the mid section of the channel member 18 which extends perpendicularly to the tube and a pipe 22, 24 extends between each outer end portion of the member 18 and a point 26 on the tube 16. The gusset plates 20 are connected between the tube 16 and the member 18 in conventional fashion.

I prefer that the tube 16 be 6 inches OD. l l gage steel tubing which is commercially available and which will be adequately rigid, but yet not overly heavy. Further, I prefer that the pipes 22, 24 be commercially available lhinch O.D. steel pipe and that the channel member 18 be a l-linch X 3 inch steel channel. I have found that it is desirable to weld a flat steel plate across the upper edges of the sidewalls of the channel member 18, thereby to provide a hollow member having a rectangular cross section. It is for this reason that, in the drawings, the member 18 appears to have such a rectangular cross section.

I also prefer that the length of each pipe 22, 24 be just slightly less than the total length of the member 18 and that the angle between each pipe 22, 24 and the tube 16 be approximately 30".

l have illustrated a conventional basketball goal 30 connected to the tube I6 at its end remote from the member 18. Specifically, an inverted L-shaped member 32 is connected to each side of the tube I6 (only one member 32 being shown) and the goal 30 is connected to the L-shaped members as indicated at 34.

I prefer to provide the boom I2 with an eye bolt 38 disposed at each end of the member 18 and arranged to mount the boom 12 for pivotal movement about a generally horizontal axis. It will be understood that these eye bolts 38 are merely illustrative and that other types of connecting means may be used pivotally to mount the boom 12.

When the boom I2 is in its lower, use position shown in solid lines in FIG. 2, the bankboard of the goal 30 is perpendicular to the playing floor of the gymnasium in which the support means 10 is mounted. When the boom I2 is lifted to its storage position shown in broken lines in FIG. 2, the bankboard of the goal 30 will form an acute angle with the playing floor.

The second boom 14 is arranged to engage the first boom I2 and to hold the first boom against pivotal movement rearwardly from its lower, use position shown in FIG. 2. Referring to the drawings, it will be seen that this boom 14 comprises a pair of spaced-apart, longitudinally-extending

pipes

44, 46. a pair of diagonally-extending

pipes

48, 50 and a channel member 18. The upper ends of the

pipes

44,46 are connected to spaced-apart portions of the midsection of the member 52 and a

pipe

48, 50 is connected between each outer end portion of the member 52 and a

point

54, 56 intermediate the ends of the

adjacent pipe

44, 46. A pipe 58, which extends parallel to the member 52, is connected between the

pipes

44, 46 at the points indicated at 54, 56. For a reason to be discussed hereinafter, a sleeve 60 is journaled for rotation on the pipe 58.

The ends of the

pipes

44, 46 remote from the member 52 are connected by a member 64 having a part circular cutout 66 therein (FIG. 3) for engaging the tube I6. The member 64, which serves as a stop means, is fastened to the

pipes

44,46 by fastening elements 70, 72 (FIG. 3).

The

pipes

44, 46, 48, 50 may be l-Vainch steel pipes welded together and welded to the member 52. Likewise, the sleeve 60 may be placed on the pipe 58 before it is welded between the

pipes

44, 46.

It will be seen that the pipe 58 extends above the tube I6 and across its path of movement and that the member 64 extends below the tube 16 and across its path of movement.

The boom 12 further comprises a

pipe

76, 78 extending parallel to the member 18 and between each pipe 22, 24 and the tube 16. A

sleeve

80, 82 is journaled on each of these

pipes

76, 78. When the boom 12 is lifted in the direction of the arrow 84 (FIG. 2), each

sleeve

80, 82 will rollably engage the

pipe

44, 46 extending thereabove to lift the boom I4 in the direction of the arrow 86. After the boom 12 has been lifted approximately 30, the tube 16 will engage the sleeve 60 to lift the boom 14 to its upper position illustrated in broken lines in FIG. 2.

The

sleeves

80, 82 will roll, respectively, against the

pipes

44, 46 and the sleeve 60 will roll on the tube 16. The rolling action provided by the

sleeves

60, 80, 82 assures smooth manipulation ofthe booms l2, 14.

It will be appreciated that the

pipes

76, 78 with the

sleeves

80, 82 thereon act as stop means for engaging and holding the boom 14 in its lower position. That is, the

pipes

76, 78 and the

sleeves

80, 82 disposed thereon prevent pivotal movement of the boom 14 from its lower position in the direction opposite to the arrow 86.

I have illustrated a portion of a cable which is usable with a pulley system to lift the boom 12 to its storage position, the cable being connected to the tube 16 as indicated at 92. The booms I2 and 14 are biased by gravity to their lower'positions illustrated in FIG. 2.

Thus, my support means 10 comprises a first boom I2 which is swingable about a first generally horizontal overhead axis and a second boom 14 which is swingable about a second generally-horizontal overhead axis which is parallel to and spaced forwardly of the first axis, the distal region of the second boom being operatively connected to the first boom for movement longitudinally of the first boom. Stop means including each

pipe

76, 78 and its

respective roller sleeve

80, 82 is provided on the first boom 12 for limiting the travel of the distal region of the second boom 14 toward the distal region of the first boom. Stop means including the brace member 64 is carried by the second boom and arranged to embrace the first boom 12 in the region between the member 18, i.e., the pivot axis of the boom 12, and the

pipes

76, 78. Further, lifter means including the flexible strand 90 is provided for raising the boom 12 and boom 14 to their respective upper positions.
