Description

FIELD OF THE INVENTION

The present invention relates to the field of basketball, and more particularly to an insertion device for the reduction in the diameter of the basketball ring for, among other things, improved basketball shooting.

BACKGROUND OF THE INVENTION

The instant invention relates to improving the game of basketball. Generally the game entails a rim of generally fixed diameter of 18 inches through which a ball, generally of fixed diameter 9.39 inches is passed. The rim is cantilevered from a backboard, enabling bank shots (wherein the ball first hits the backboard to which the rim is attached) and either passes through the rim or bounces away, and “swoosh” shots wherein the ball passes through the rim directly. In the game, hung from hooks on the rim is a net through which a successful shot passes.

The improvement sought by the instant invention is a removably mounted ring assembly that is inserted into the rim, clippably attached thereto for ease of attachment and detachment, and decreases the diameter of the ring. In this manner, the shooter is required to improve both the bank shot and the “swoosh” inasmuch as the ring is smaller in aperture when the device of the instant invention is attached.

There is nothing in the prior art known-to the inventor that actually changes the size of the rim diameter. Rather the prior art shows various hoop assemblies for a plethora of other purposes. For example, U.S. Pat. No. 4,858,920 shows a sensor arrangement for indicating a successful shot wherein the ball passes through the rim and hence constitutes a “score.” U.S. Pat. No. 6,458,050 shos a detachably mounted pin for striking by the shooter to improve accuracy, but fails to indicate any change in the size of the rim. U.S. Pat. No. 4,993,707 shows a strapping assembly to enable the shooter to strap a hand to the ball thereby improving dunking of the ball. U.S. Pat. No. 5,480,139 shows a device designed to improve with interchangeable basketball hoops, but does suggest nor reveal a mechanism for utilizing a standard rim and decreasing its diameter, as is the case herein. U.S. Pat. No. 5,628,507 shows a basketball goal protector to prevent use of the field by blocking access to the rim and net. U.S. Pat. No. 4,082,269 shows a net installation device wherein the net attaches to an annular rim for insertion into the rim to provide the net, thereby eliminating the hooks typically present on the rim in known devices. It does not, however, show a reduction in the diameter of the rim to improve shooting ability; rather the device is intended to maintain the universal rim regulation rim size.

Likewise, U.S. Pat. No. 4,244,560 shows an extension device for extension into the center of the rim, for increasing shooting accuracy, but does not reveal a change in the rim diameter, as is the case herein.

It is thus an object of the instant invention to change the diameter of the rim in a basketball gaming backboard-mounted, cantilevered rim assembly, while maintaining the rim's overall resiliency and other typical facets, to increase the accuracy of the shot taken by the shooter for either practice or regulation play.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In accordance with the subject invention, FIG. 1 shows rim insertion device 4 for insertion into typical basketball rim 8 such that the assemblage of device 4 and rim 8 form a unified structure as provided by a plurality of hooking apertures and/or hooking assemblies, as shown in further detail hereinbelow, one of which is shown as hooking aperture 14A in FIG. 1. As is shown by the dotted line in FIG. 1, rim insertion device 4 is inserted and hookably attached to rim 8. In a typical basketball rim conglomerate, as shown in FIG. 1, for which the subject invention is an addition, rim 8 possesses hooks 10 for engaging a net (not shown but known to one of ordinary skill in the art), and is cantilevered from backboard 2 via right-angled mounting 6 which annexes from background 2 to rim 8.

As is observable via FIG. 1, once rim insertion device 4, in accordance with the subject invention is rigidly mounted to rim 8 (via apertures and/or hooking assemblies as shown in further detail hereinbelow) the size of the aperture through the which the ball travels is reduced. In this manner, the shooter is caused to improve the accuracy of the shot for a typical “swoosh” wherein the ball neither touches rim 8 nor the net (not shown) or a bank shot wherein the ball banks from backboard 2 through rim insertion device 4 (and hence rim 8).

It should be observed that rim insertion device 4 is rendered of a comformable yet rigid material such that when assembled to rim 8 it essentially becomes “one” with rim 8 and does bounce between the two. Typically such materials include, but are not limited to a polyvinyl (e.g., “PVC” or polyvinylchloride) or metal, or metal-coated materials that have rigidity and flexibility that does not substantially change the characteristics of original rim 8. Observably, the preferred material is a plastic of sorts inasmuch as such material is lightweight and will not substantially change either the characteristics of original rim 8 nor its overall cantilevered weight such that the game, itself, does not substantially change by way of a difference in bounce, save for a difference in the diameter of the hole through which the ball will pass.

Typical regulation rims are generally 18 inches in diameter; rim device 4 provides any of a number of smaller apertures (18.1 through about 10 inches) through which the ball (generally having a regulation diameter of 9.39 inches) must pass, and therefore large enough to enable the ball of such fixed diameter to pass therethrough.

FIG. 2, showing a perspective view of rim device 4 with ball 12 passing therebetween, also shows rim device 4 fixedly, yet removably attached to rim 8 (covered in the view by device 4), via plurality of apertures and/or hooking assemblies, as further discussed hereinbelow. All other items of the view conform with those shown in FIG. 1.

FIG. 3 reveals the downward view of rim device 4 having an extended portion 4A for overlapping the cantilever mount 6 (see FIG. 1) and a plurality of hooking apertures below the top surface, as shown in FIGS. 4 through 9.

In particular, FIG. 4 shows cross-sectional view of a hooking aperture 14A which engages rim 8 (not shown) via its aperture 18A of a diameter of sufficient angulature 22 such that rigid conformation may occur, together with removal and attachment via its aperture 18A. Relatively planar surface 16 is actually a view, in this embodiment, of the surface of rim device 4, as shown in FIG. 3, and is identical in each of FIGS. 3 through 9.

FIGS. 4 through 9 indicate cross-sectional views of hooking apertures 14 A through F respectively, and reveal apertures of three different sizes, to accommodate the goal of relatively rigid attachment of device 4 to rim 8. Thus, FIG. 5 has aperture 18B, as does FIG. 6. FIGS. 4, 7 and 8 have relatively the same aperture 18A, while FIG. 9, which is designed to accommodate the surface of cantilever mount 6, possesses a flat extended surface 24, and an aperture 18F. The apertures are created by terminals of the aperture 20A (as shown in FIGS. 4, 7, 9), and terminals 20B (as shown in FIGS. 5 and 6).

FIG. 10 reveals attachment of device 4 with surface 16, cross-sectional view of aperture 14F with extension 24 (as shown in FIG. 9) wherein rim 8 is displaced within aperture 14F. Ball 12 engages device 4, with potential compression as it intersects of distance 34, dependent upon the material used. As is known in the art, rim 8 also has net hooks 10, of which one is shown, for engagement of a net (not shown but known to one of ordinary skill in the art).

As can be seen, the exterior of device 4 may be comprised of a more compressible material (like a polyurethane), if two different materials are selected. In the preferred embodiment the structure is shown as a single material. If a more compressible external material is provided, then distance 34 will compress accordingly.

Likewise, FIG. 11 shows ball 12 intersecting the top surface 16 of device 4. All other elements are the same as those shown in FIG. 10.

FIG. 12 indicates an alternative embodiment wherein surface-mounted hooking assemblies 28 and/or 28 A (see FIGS. 13 and 14, respectively) are perpendicularly mounted to the rear surface as shown by and dotted lines 26. Each of hooking assemblies 28 and/or 28A, as shown in FIGS. 13 and 14, respectively, have apertures 18A, and possesses cutouts 30 and 32 of sufficient size to reduce the overall weight of device 4 when engaged to the rear surface via relatively planar surface 16.

FIGS. 15, 16 and 17 shows yet an additional, alternative embodiment wherein device 50 is tubular in design to accommodate rings 8 of differing diameters. Thus, device 50 includes outer tube assembly 38 to which are annexed hooking assemblies 40 for engagement of rim 8. Circle 16 in FIG. 15 conforms with FIG. 16, which is an expanded view, wherein a hooking assembly 40 is shown annexed to outer tube 38, and in which inner tube 44 is shown to engage another portion of outer tube 40 by passing therein, and through which cotter pin 46 passes through an aperture on tube 38 and aperture 42 in inner tube 42 for assembly. In order to accommodate rings of different sizes, stops 48 on inner tube 44, as shown in FIG. 17 are supplied to expand or contract the device by slidably moving outer tube 38 upon inner tube 44 to engage stops 48.

While there have been shown, described and pointed out fundamental novel features of the invention as applied to preferred embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
