The present disclosure deals with basketball goal assemblies and particularly basketball rim assemblies.
Basketball is a popular sport that can be played by anyone who has access to a ball and a basketball goal. Basketball goals have become common to find in driveways and public parks. For such goals to be assembled and/or installed they need to be packaged and transported to the desired location either by a consumer or an installer. It can then take time for the consumer or installer to assembly the various components into an assembled basketball goal. Furthermore, assembled and/or installed goals can take up significant space even when not in use.
For game play, the basketball rim assembly needs to be securely mounted to extend perpendicular to the face of the basketball backboard. In certain arrangements a rim assembly may incorporate a break-away feature, allowing the rim to resiliently pivot downward a short distance when impacted by a force, such as a player hanging from the rim. The rim assembly returns to a static playing position when the force is released. However, the inclusion of a break-away feature typically significantly increases the bulk and complexity of the rim assembly.
To facilitate assembly and installation of the goal, it would be desirable in some situations for the basketball rim assembly to arrive already connected to the backboard. However, since the rim assembly typically extends perpendicular to the backboard, a pre-attached fixed rim assembly can make packaging and transport unwieldy and impractical. Further, an extending rim assembly can require more room for storage. Some prior art references suggest arrangements where a rim assembly can be folded upward and parallel to the backboard so that the rim assembly does not protrude when not in use. However, such upward folding arrangements are often incompatible with break-away mechanisms which allow downward pivoting.
Some basketball rim assemblies include a break-away mechanism based on a coil spring arrangement. In representative examples, one or more coil springs are arranged with the spring axis perpendicular to the basketball rim or with an axis perpendicular to the backboard. A shaft, such as a bolt extends through the central axis of the coil spring. The coil spring is captured with one end bearing against a plate surface of the rim assembly which the shaft passes through. The other spring end is held using a cap arrangement, such as a washer with a diameter larger than the spring which is held on the shaft with a threaded nut or similar fastener. The plate surface is arranged to move along the shaft to compress the spring against the cap arrangement when force is applied.
In some arrangements, the consumer or installer has to assemble the components, including placing each spring over each corresponding shaft and securing it with a cap arrangement. This requires the proper assembly of multiple components, including adjusting the spring tension to provide the correct amount of resistive force, without too much or too little resistance. Alternately, if a coil spring arrangement is transported pre-assembled it adds to the manufacturer's cost, it is transported under significant tension and it is more bulky and awkward to package and transport. Moreover, any arrangement with a coil spring and cap arrangement involves more components, which increases the cost and complexity of assembly. Furthermore, when there are more components, there is an increased chance of components being omitted, getting lost, breaking or loosening over time.
In certain embodiments, the present disclosure provides rim assemblies which are attached or which are configured to be attached to or with a basketball backboard. The backboard may be mounted to a support member such as a support pole. The basketball goal is arranged to be in a playing position relative to a support surface such as the ground or a floor.
Illustrated embodiments include a rim assembly with a mounting bracket and a rim bracket connected by an axle forming a hinge. The mounting bracket is mountable to the backboard assembly and/or support structure. The rim bracket forms a portion of and/or is connected to a basketball rim. In certain embodiments, the rim bracket is rotatable approximately ninety degrees relative to the mounting bracket between a playing position and a folded position. In the upward or folded position the rim bracket and rim extend substantially parallel to the backboard. In the playing position, the rim bracket and rim extend perpendicular to the backboard.
In certain embodiments, the rim assemblies include a locking mechanism to selectively retain the rim assembly in the folded position or the playing position. In one illustrated embodiment, the locking mechanism includes a pair of retaining pieces such as locking buttons on the ends of respective leaf springs mounted to the rim bracket. The locking buttons resiliently extend laterally through openings in side flanges of the rim bracket. In the respective folded position or playing position, the locking buttons further extend through respective folded position openings or playing position openings in side flanges of the mounting bracket. The rim assembly can be unlocked by resiliently pressing the locking buttons inward from the openings corresponding to the current rim bracket position, allowing the rim bracket to be rotated to the other position, where the locking buttons will extend to engage the other pair of folded position openings or playing positions opening. In certain embodiments where a folding rim assembly also incorporates a break-away mechanism, the playing position openings may be elongated to allow some breakaway movement of the rim during play.
In another illustrated embodiment, the locking mechanism includes a retaining piece such as a retaining pin. Opposing ends of the retaining pin extend laterally through openings in side flanges of the rim bracket and the mounting bracket. The rim assembly can be unlocked by selectively removing the retaining pin, allowing the rim bracket to be rotated from a playing position to a folded position. In certain embodiments where a folding rim assembly also incorporates a break-away mechanism, openings for the retaining pin in the side flanges may be elongated and/or oval shaped to allow some breakaway movement of the rim during play. In an aspect which may be combined or use separately from the folding aspect of the rim assembly, a breakaway mechanism may incorporate an elongate rim leaf spring. The rim leaf spring has a lower end anchored to the mounting bracket. The leaf spring extends upward and a middle portion curves forward. The middle portion may abut the axle, which forces the leaf spring to maintain a curved orientation. An upper end of the rim leaf spring abuts the rim bracket in the playing position. The rim leaf spring biases the rim bracket upward and resists downward pivotal movement. Downward movement may occur when a player hangs from the rim.
In some embodiments the path of the unflexed leaf spring may extend slightly above a plane defined by the rim bracket's playing position, so that the spring contacts the rim bracket and a preload is applied as the rim bracket approaches and is placed into the playing position.
Further objects, features and advantages of the present disclosure shall become apparent from the detailed drawings and descriptions provided herein.
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the disclosure as illustrated therein being contemplated as would normally occur to one skilled in the art to which the disclosure relates.
In certain embodiments, the present disclosure provides rim assemblies which are attached or which are configured to be attached to or with a basketball backboard. The backboard may be mounted to a support member such as a support pole. The basketball goal is arranged to be in a playing position relative to a support surface such as the ground or a floor. Illustrated embodiments include a rim assembly with a mounting bracket and a rim bracket connected by an axle forming a hinge. The mounting bracket is mountable to the backboard assembly and/or support structure. The rim bracket forms a portion of and/or is connected to a basketball rim. In certain embodiments, the rim bracket is rotatable approximately ninety degrees relative to the mounting bracket between a playing position and a folded position. In the upward or folded position the rim bracket and rim extend substantially parallel to the backboard. In the playing position, the rim bracket and rim extend perpendicular to the backboard. Certain embodiments of the rim assemblies include a locking mechanism to selectively retain the rim assembly in the folded position or the playing position. In one illustrated embodiment, the locking mechanism includes a pair of locking buttons on the ends of respective leaf springs mounted to the rim bracket. The locking buttons resiliently extend laterally through openings in side flanges of the rim bracket. In the respective folded position or playing position, the locking buttons further extend through respective folded position openings or playing positions openings in side flanges of the mounting bracket. The rim assembly can be unlocked by resiliently pressing the locking buttons inward from the openings corresponding to the current rim bracket position, allowing the rim bracket to be rotated to the other position, where the locking buttons will extend to engage the other pair of folded position openings or playing positions openings. In certain embodiments where a folding rim assembly also incorporates a break-away mechanism, the playing position openings may be elongated to allow some breakaway movement of the rim during play.
In another illustrated embodiment, the locking mechanism includes a retaining piece such as a retaining pin. Opposing ends of the retaining pin extend laterally through openings in side flanges of the rim bracket and the mounting bracket. The rim assembly can be unlocked by selectively removing the retaining pin, allowing the rim bracket to be rotated from a playing position to a folded position. In certain embodiments where a folding rim assembly also incorporates a break-away mechanism, openings for the retaining pin in the side flanges may be elongated and/or oval shaped to allow some breakaway movement of the rim during play.
In an aspect which may be combined or use separately from the folding aspect of the rim assembly, a breakaway mechanism may incorporate an elongate rim leaf spring. The rim leaf spring has a lower end anchored to the mounting bracket. The leaf spring extends upward and a middle portion curves forward. The middle portion may abut the axle, which forces the leaf spring to maintain a curved orientation. An upper end of the rim leaf spring abuts the rim bracket in the playing position. The rim leaf spring biases the rim bracket upward and resists downward pivotal movement, for instance due to a player hanging from the rim.
In certain embodiments the path of the unflexed leaf spring extends slightly above a plane defined by the rim bracket's playing position, so that the spring contacts the rim bracket and applies a preload as the rim bracket approaches and is placed into the playing position.
In some embodiments, support pole 30 may be monolithic; however, in other embodiments, support pole 30 may include two or more portions connected together. Support pole 30 may have a curved cross-section such as a circular or oval shape, a rectangular cross-section, or it may have a cross-section of any other desired shape.
The lower portion 32 of support pole 30 is mounted relative to the support surface, for example by being attached to a base 60. Base 60 may be portable. Support pole 30 may be angled so pole 30 extends obliquely from base 60 relative to the support surface. In other embodiments support pole 30 is vertical and extends perpendicular to the support surface. In some embodiments, pole 30 may be secured directly into the ground or to a base anchored in the ground. In other embodiments, backboard assembly 20 may be mounted to a wall or from a ceiling.
In the illustrated embodiment, a support system extends between backboard assembly 20 and an upper portion 34 of support pole 30. As shown in
Support arms 42, 44 create a deformable parallelogram assembly for adjusting the backboard height. Rearward points on support arms 42, 44 may each be pivotally attached to support pole 30 along a vertical axis forming the rearward side of the parallelogram. Forward ends of support arms 42, 44 may each be pivotally attached to backboard assembly 20 along a vertical axis. The forward ends of the support arms may be attached directly to a rearward side of backboard assembly 20 or alternately the forward ends may be attached to a bracket 46 to which backboard assembly 20 is secured. Depending on the embodiment, backboard assembly 20 may be secured to bracket 46 either before or after the support arms 42, 44 are attached to bracket 46. The backboard assembly 20 and/or bracket 46 is vertical and forms the forward side of the deformable parallelogram.
Optionally, the ends of one or more support arms 42, 44 may extend rearward past support pole 30 and may provide attachment points for additional features of basketball goal assembly 10. For example, a height adjustment mechanism (not shown) may be attached between lower support arms 42 and a central portion of pole 30. In one example, the height adjustment mechanism may be a worm gear/piston cylinder based mechanism with a manual crank for adjustment. A balancing structure, such as springs or weights in or on the support arms, may help keep the backboard weight close to neutrally balanced relative to the pole so that it takes a minimum force applied to the rear of the support arms to raise or lower the backboard.
As illustrated in
Details of a representative embodiment of rim assembly 110 are illustrated further in
Mounting bracket 120 includes side flanges 124 which are bent forward relative to rear portion 122. Side flanges 124 are planar and extend vertically. Side flanges 124 are perpendicular to rear portion 122. Side flanges 124 define a pair of aligned mounting axle openings, at least one and optionally a pair of aligned folded position openings 152 illustrated as circular and at least one and optionally a pair of playing position openings 154 illustrated in the shape of an elongated slot or oval.
Rim assembly 110 further includes rim bracket 130. Rim bracket 130 includes a planar top portion 132. A circular rim 140 extends outward and forward from top portion 132. Rim 140 is secured in a plane with top portion 132, for example by welding. Rim 140 may be of a conventional size for the game of basketball and may include mounting hooks for a net. Rim bracket 130 includes side flanges 134 which are bent forward relative to top portion 132. Side flanges 134 extend vertically and are perpendicular to top portion 132. Side flanges 134 are parallel to side flanges 124 of mounting bracket 120. Side flanges 134 define a pair of aligned mounting axle openings, at least one and optionally a pair of aligned folding spring mounting openings 162 and at least one and optionally a pair of aligned folding spring button openings 164.
As assembled, rim bracket 130 is nested between side flanges 124 of mounting bracket 120. The axle openings of rim bracket 130 and mounting bracket 120 are aligned, with rim bracket 130 pivotally mounted to mounting bracket 120 via an axle 144 extending through the aligned axle openings. Axle 144 is preferably locked at each end, for example with a cap, a fastener or a stamped end, to prevent unintended removal of axle 144. Rim bracket 130 is pivotal relative to mounting bracket 120 around the axis of axle 144. In the playing position, top portion 132 of rim bracket 130 is perpendicular to rear portion 122 of mounting bracket 120. Correspondingly, in the folded position, top portion 132 of rim bracket 130 is parallel to rear portion 122 of mounting bracket 120. Additionally in the playing position, the outer face 133 of top portion 132 is flush with upper edge 128 of mounting bracket 120. Ideally for safety, there are minimal gaps between rim bracket 130 and upper edge 128 of mounting bracket 120 in the playing position, yet allowing sufficient clearance for rim assembly 110 to rotate between the playing position and the folded position when desired.
In the illustrated embodiment, rim assembly 110 includes a locking mechanism to selectively retain the bracket in the folded position or the playing position. Illustrated in detail in
A retaining piece such as locking button 174 is arranged at an opposing end of strip 171 from mounting stud 172. Locking button 174 is perpendicular to the plane of strip 171 and extends into a folding spring button opening 164 of rim bracket 130. Each locking button 174 has a height or thickness at least sufficient to engage the combined thicknesses of flanges 124 and 134 and optionally may extend slightly outward beyond flange 124.
Locking button 174 is arranged to sequentially align with folded position opening 152 and playing position opening 154 defined in side flange 124 during rotation of rim bracket 130 relative to mounting bracket 120. As one arrangement, the locking button can be arranged to travel at a fixed radius offset from the axis of axle 144. When locking button 174 comes into alignment with either folded position opening 152 or playing position opening 154, the folding spring biases locking button 174 laterally outward so that the height of locking button 174 extends through both side flanges 124 and 134, whereupon the shear strength of the locking button locks the side flanges, preventing further rotational movement until locking button 174 is disengaged.
The rim assembly can be unlocked by resiliently pressing the locking buttons inward from the locking openings. Strip 171 has a sufficient length, flexibility and clearance to allow locking button 174 to be resiliently pressed inward against the biasing force of folding spring 170 a sufficient distance that locking button 174 disengages from the currently aligned opening in mounting bracket side flange 124, enabling rotation of rim bracket 130 relative to mounting bracket 124.
Embodiments of the rim assembly may incorporate a breakaway mechanism. A breakaway mechanism allows the rim bracket to resiliently rotate slightly downward when force is applied to the rim and causes the rim bracket to return to a static position when the force is released.
In the embodiment illustrated in
As used herein, a leaf spring means an elongate beam or flat type of spring such as a strip of a substantially planar sheet or plate material with an elongated length, a width and a thickness. The strip maintains a fixed shape along its length, either a curved or a flat shape, in an unflexed state. The strip has a spring strength that resists being flexed, yet when flexed the strip is biased to return to an un-flexed shape. Rim leaf spring 180 may be made of high strength metal materials which are flexible yet with significant spring strength such steel, stainless steel or aluminum. In alternate embodiments, rim leaf spring may be made of a strip of non-metal material such as a plastic or rubber with a sufficient flexibility and spring strength.
Rim leaf spring 180 has a lower end 182 which converges with and becomes parallel to abut the inner face of mounting bracket rear portion 122. Lower end 182 may be anchored to rear portion 122, for example with a pair of clamping tabs 126. When installed on a backboard assembly, lower end 182 may be further anchored with a fastener, such as a bolt, extending through a mounting opening 183 aligned with a bracket mounting opening 121. The fastener may assist in securing the spring and the bracket to the backboard assembly.
The length of rim leaf spring 180 extends upward from lower end 182, and is arranged with a mid-portion 184 which curves forward. In certain embodiments, mid-portion 184 is held in a curved orientation by axle 144, where mid-portion 184 contacts axle 144 tangentially. When used in a foldable rim assembly as illustrated, leaf spring 180 is retained in the curved orientation by the combination of anchored lower end 182 and abutment against axle 144 regardless of whether rim assembly 110 is in the playing position or the folding position.
The length of rim leaf spring 180 continues to extend upward from mid-portion 184 to upper end 186. Upper end 186 continues the curve of mid-portion 184, and may transition to a flat portion which is substantially horizontal.
As illustrated in cross-section in
In certain embodiments, the unflexed path of leaf spring upper end 186 does or would extend to a vertical height higher than plane D-D, as illustrated for example in
When a break-away mechanism using rim leaf spring 180 is used in combination with a folding rim assembly as illustrated, the folding and locking arrangement needs to accommodate the break-away action. In the representative embodiment, this is accommodated via the shape of playing position openings 154. In example embodiments, playing position openings 154 are defined each with an elongated slot or oval.
As illustrated in detail in
Additionally, the elongated or oval shape of playing position opening 154 allows the retaining piece such as locking button 174 to translate within playing position opening 154 when the rim 140 and rim bracket 130 pivot forward and downward under a break-away movement. This translation movement allows the rim bracket to pivot slightly downward separately yet in addition to the ability to fold the rim assembly upward. Upon release of the break-away force, rim leaf spring 180 urges rim bracket 130 upward to the static position and returns locking button 174 to abut the forward edge of playing position opening 154. In example embodiments, the elongated slot or oval defined by playing position openings 154 has a major axis which is substantially horizontal, optionally with a slight angle and/or a slight radial curve to accommodate radial movement of locking button 174 as rim bracket 130 rotates.
Details of an alternate embodiment of a rim assembly 210 are illustrated in
Mounting bracket 220 includes side flanges 224 which are bent forward relative to rear portion 222. Side flanges 224 are planar and extend vertically. Side flanges 224 are perpendicular to rear portion 222. Side flanges 224 define a pair of aligned mounting axle openings and a pair of aligned outer pin openings 252 illustrated as circular in shape.
Rim assembly 210 further includes rim bracket 230. Rim bracket 230 includes a planar top portion 232. In the same manner as in rim assembly 110, rim 140 extends outward and forward from top portion 232. Rim bracket 230 includes side flanges 234 which are bent relative to top portion 232. Side flanges 234 extend vertically and are perpendicular to top portion 232. Side flanges 234 are parallel to side flanges 224 of mounting bracket 220. Side flanges 234 define a pair of aligned mounting axle openings and a pair of aligned inner pin openings 262 illustrated as elongated or oval in shape.
As assembled, rim bracket 230 is nested between side flanges 224 of mounting bracket 220. The axle openings of rim bracket 230 and mounting bracket 220 are aligned, with rim bracket 230 pivotally mounted to mounting bracket 220 via an axle 244 extending through the aligned axle openings. Axle 244 is preferably locked at each end, for example with a cap, a fastener or a stamped end, to prevent unintended removal of axle 244. Rim bracket 230 is pivotal relative to mounting bracket 220 around the axis of axle 244. In the playing position, top portion 232 of rim bracket 230 is perpendicular to rear portion 222 of mounting bracket 220. Correspondingly, in the folded position, top portion 232 of rim bracket 230 is parallel to rear portion 222 of mounting bracket 220. Additionally in the playing position, the outer face 233 of top portion 232 is substantially flush with upper edge 228 of mounting bracket 220. Ideally for safety, there are minimal gaps between rim bracket 230 and upper edge 228 of mounting bracket 220 in the playing position, yet allowing sufficient clearance for rim assembly 210 to rotate between the playing position and the folded position when desired.
In the illustrated embodiment, rim assembly 210 includes a locking mechanism to selectively retain the assembly in the folded position or the playing position. Illustrated in detail in
Retaining pin 270 can be selectively installed in rim assembly 210 to hold rim assembly 210 in the playing position. When desired, retaining pin 270 can be removed, allowing rim assembly 210 to be folded by rotating bracket 230 and rim 140 upward. Retaining pin 270 is removed in
In the embodiment illustrated in
As illustrated in cross-section in
In certain embodiments, the unflexed path of leaf spring upper end 286 does or would extend to a vertical height higher than plane D-D, as illustrated for example in
In the embodiment of
Optionally, rim bracket 230 may also incorporate stop tabs 238 extending laterally inward adjacent the lower edges of rim bracket side flanges 234. Stop tabs 238 are spaced slightly forward of mounting bracket rear portion 222 in the playing position. When rim bracket 230 is rotated downward under pressure, stop tabs 238 may rotate rearward into engagement with rear portion 222 consequently limiting further rotation.
Folding rim assemblies using versions of the disclosed folding bracket and locking arrangement can be packaged and transported pre-mounted to certain backboard assemblies. Alternately, folding rim assemblies such as disclosed can be sold separately or packaged with a backboard for on-site mounting. As illustrated in
While the disclosure has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
The present application is a continuation of U.S. patent application Ser. No. 16/507,491 filed Jul. 10, 2019, which claims the benefit of U.S. provisional application No. 62/745,592 filed on Oct. 15, 2018, both of which are incorporated by reference.
