Abstract
This invention is a break-away basketball goal apparatus having numerous embodiments but basically a feature whereby downward pressure on a basketball rim assembly causes the same to pivot or release to prevent damage to a backboard member. A few embodiments utilize biasing means to automatically restore a released rim assembly to its normal, horizontal usage condition. Other embodiments have an actuator latch assembly positioned in a concealed manner behind the backboard member. One other embodiment is a backboard break-away latch goal assembly wherein a portion of the backboard member with a rim assembly attached thereto breaks away on downward pressure applied thereto. It is the purpose of the break-away basketball goal apparatus to release a rim assembly when excessive pressure is applied thereto (normally by a basketball player during a dunking operation) to prevent breakage of the backboard member.

DESCRIPTION OF THE INVENTION
The break-away basketball goal apparatus of this invention consists of numerous embodiments including combinations of a main support housing, a releasable rim assembly pivotally connected to the main support housing; and an actuator latch assembly connected to the main support housing and the rim assembly. Each of the actuator latch assemblies are operable to hold the rim assembly in a normal, horizontal usage condition but permits its movement to a vertically inclined position on application of excessive pressure thereto. Each embodiment is (1) either connectable to an existing backboard member; (2) connectable to a modified backboard member; or (3) constructed as a part of a backboard member that has a portion that breaks away under excessive pressure. The numerous embodiments of the break-away basketball goal apparatus are discussed in detail hereinafter.
Spring Latch Goal Assembly Embodiment
As collectively shown in FIGS. 1, 2, and 3, a spring latch goal assembly, indicated generally at 12, is shown as connected to a generally conventioal backboard member 14. the backboard member 14 is of a regulation shape and may be constructed of glass, metal, or wood and supported against a wall, a roof, or on a pole. A mid portion 16 of the backboard member 14 supports the spring latch goal assembly 12 in a conventional manner as by nut and bolt members 18.
The spring latch goal assembly 12 includes a main support housing 19 secured to the backboard member 14, a releasable rim assembly 20 pivotally connected to the main support housing 19, and an actuator latch assembly 22 secured to the main support housing 19 and operably connectable to the rim assembly 20.
The main support housing 19 includes a connector housing 24 with a cover assembly 26 connected thereto. The connector housing 24 includes a rectangular back plate 28 with forwardly projecting parallel side plates 30 secured to opposed, upright edges 32 of the back plate 28. The back plate 28 is formed with a plurality, namely four, holes 34 therein to receive the nut and bolt members 18 for securing to the backboard member 14. A forward portion 36 of each side plate 30 has aligned holes 38 to receive a portion of the rim assembly 20 as will be explained.
The cover assembly 26 includes an inclined cover plate 40 secured by bolt members 42 to nut members 43 which, in turn, are secured as by welding to respective side plates 30. The cover plate 40 functions to shield the actuator latch assembly 22.
The releasably rim assembly 20 includes a standard rim member 45; a top cover housing 46 secured to the rim member 45; a connector shaft member 47 connected to the top cover housing 46 and the main support housing 19; and a lock shaft assembly 48 secured to the top cover housing 46.
The standard rim member 45 is regulation size and includes the ring member 50 having a plurality of spaced net hangers 51 about its periphery to connect a basketball net thereto (not shown).
The top cover housing 46 is of U-shape in transverse cross section having a top wall 53 and integral sidewalls 54. The top cover housing 46 conceals the actuator latch assembly 22 when in the usage position of FIG. 1.
The connector shaft member 47, as shown in FIG. 3, extends through the sidewalls 54 and the side plates 30 and allows pivotal movement of the entire releasable rim assembly 20 thereabout as shown in dotted lines in FIG. 2.
As noted in FIG. 3, the lock shaft assembly 48 includes a plurality, namely three, spaced support lugs 56 secured to a bottom surface 57 of the topwall 53 and having aligned holes 59 therein to receive and support a latch or lock shaft 60. The lock shaft 60 cooperates with the actuator latch assembly 22 in a manner to be described.
The actuator latch assembly 22 includes a latch support base assembly 62; a pair of space cooperating actuator arms 64 pivotally connected to the latch support base assembly 62; and a biasing assembly 66 operably connected to the two sets of actuator arms 64. The latch support base assembly 62 includes a support base member 68; spaced lug members 70 secured to the support base member 68; a pair of spaced latch support shafts 72 mounted in aligned holes 74 in the lug members 70; and an alignment arm assembly 76 secured to the support base member 68. The support base member 68 is of a rectangular steel bar shape having opposite ends 78 secured, as by welding, to inner surfaces 79 of the respective side plates 30.
Each latch support shaft 72 is held in proper axial location in the lug members 70 by lock pins 80 inserted in holes at opposite ends thereof.
The alignment arm assembly 76 includes a support arm 82 secured to support base member 68 and the central lug member 70 and having a horizontal spring support member 84 secured to an upper end of the support arm 82.
The facing pairs of actuator arms 64 cooperate with each other similar to a clothes pin (see FIG. 2) with each having a connector portion 86 integral with a central portion 88 which, in turn, is integral with a top clamp portion 90. Each connector portion 86 is formed with a mounting hole 92 to receive a respective latch support shaft 72 therein for pivotal movement.
Each top clamp portion 90 is formed with a top curved edge 93 leading to a notched section 95. The cooperating actuator arms 64 have the notched sections 95 operable to receive a portion of the lock shaft 60 therein in a clamped condition (FIG. 2).
As shown in FIG. 2, the biasing assembly 66 includes a support bolt member 96; a pair of bearing washers 98 mounted on the bolt member 96; a biasing member or compression spring member 102 mounted about the bolt member 96 having one end against a bearing washer 98; a washer member 106 having one side mounted against the other end of the compression spring member 102; and a nut member 108 threadably mounted on an end portion 109 of the support bolt member 96 against the other side of the washer member 106.
It is noted that the bolt member 96 has been trained through a first bearing washer 98; the space between the pairs of actuator arms 64; a second bearing washer 98; a center of the compression spring member 102; the washer member 106; and connected to the nut member 108. The nut member 108 is readily moved on the bolt member 96 to regulate compression force of the spring member 102 through the bearing washers 98 against the actuator arms 64.
USE AND OPERATION
In the use and operation of the spring latch goal assembly 12 of this invention, the structure is readily connected to the backboard member 14 at a mid portion 16 by the nut and bolt members 18. This assembly would resemble a conventional basketball goal assembly as shown in FIG. 1.
As notes in FIG. 1, the rim assembly 20 is held in the horizontal, usage position by clamping of the lock shaft assembly 48 between the cooperating pairs of the actuator arms 64. Of course, the actuator arms 64 are biased to the clamped condition by the compression spring member 102 and such holding force is easily regulated by axial movement of the nut member 108 on the threaded end of the bolt member 96.
In basketball play and practice, it is permitted to dunk the ball through the rim member 45 but one is not to hit or pull downwardly on the subject rim member 45. However, because of human error, such does not always happen and the basketball players weight may be applied on the rim member 45 which causes breakage of the backboard member 14.
However, with the spring latch goal assembly 12 of this invention, a preset downward force against the rim member 45 cuases a separation of the actuator arms 64 and release of the rimmember 45 to move to the vertically inclined condition as shown in FIG. 2. This relieves the pressure against the backbaord member 14 and prevents breakage thereof with resultant savings in material and manpower needed to repair same.
The rim member 45, after moved to the inclined released condition, can be pivoted, in the direction as shown by an arrow 110 to the normal, usage position illustrated by the solid lines in FIG. 2.
Foldable Latch Goal Assembly Embodiment
As collectively shown in FIGS. 4 and 5, a foldable latch goal assembly 112 is connectable by nut and bolt members 18 to the backboard member 14. The foldable latch goal assembly 112 includes a support housing 114; a releasable rim assembly 116 pivotally connected to the support housing 114; and an actuator latch assembly 118 connected to the support housing 114 and the releasable rim assembly 116.
The support housing 114 includes a vertical, rectangular shaped, base plate 120; parallel rim support lugs 122 secured to a central, upper portion 124 of the base plate 120; parallel spring support lugs 126 secured to the upper, outer edge portions 127 of the base plate 120; and linkage support lugs 128 secured to lower, outer edge portions 130 of the base plate 120. Each of the lugs 122, 126, and 128 has a hole 132 in the outer sections thereof for reasons to be explained.
The releasable rim assembly 116 includes the standard rim member 45 having an inner central portion 134 secured to a stop housing 136. The stop housing 136 has a top plate 138 with spaced, downwardly depending leg sections 140 and laterally extended, opposed stop members 142. The leg sections 140 are formed with aligned holes 144 to receive a support shaft 146 therethrough. The support shaft 146 also extends into the holes 132 in the rim support lugs 122 to permit pivotal movement of the releasable rim assembly 116 as shown in dotted lines in FIG. 4.
The stop members 142 contact respective upper surfaces 148 of the rim support lugs 122 to prevent pivotal movement beyond horizontal when moved in a counterclockwise direction as shown by the arrow 150.
The actuator latch assembly 118 includes a latch support base 152 connected to the rim member 45; actuator or linkage arm 154 connected to the support housing 114 and the latch support base 152; and a biasing assembly 156 connected to the linkage arm 154 and the support housing 114.
More particularly, the latch support base 152 includes a pair of linkage lugs 158 secured to opposed, respective sides of the rim member 45 and each having a connector hole 160 therein.
The linkage arms 154 includes spaced, pairs of identical first and second link members 162, 164 pivotally interconnected at one end thereof by a rivet member 165. An opposite end of the first link members 162 are pivotally connected by a rivet member 166 to the respective linkage support lugs 128. Similarly, an opposite end of the second link members 164 are pivotally connected by a rivet member 168 to the respective linkage lugs 158.
The biasing assembly 156 includes a spaced, pair of parallel tension spring members 170, each having one end section 172 connected to respective ones of spring support lugs 126 and other end sections 174 connected to respective ones of the rivet members 165.
USE AND OPERATION
In the use and operation of the foldable latch goal assembly 112, this presents an economical embodiment that is automatically spring biased to the normal, horizontal, usage position. On exerting downward pressure on the rim member 45, the first and second link members 162, 164 are movable toward the position as shown in dotted lines in FIG. 4. This is similar to linkage members shown in the prior arts as used on card tables except the longitudinal axis of the first and second link members 162, 164 are never aligned.
This movement causes a longitudinal expansion of the tension spring members 170 which inreases its force to move the rim member 45 back to the normal, horizontal usage position. This is achieved when the downward force against the rim member 45 is released and the stop members 142 contact the upper surfaces 148 of the rim support lugs 122.
Compression Latch Goal Assembly Embodiment
As collectively shown in FIGS. 6 and 7, a comrpession latch goal assembly, indicated generally at 176, is shown as secured to the backboard member 14 as by the nut and bolt members 18. More particularly, the compression latch goal assembly 176 inludes a main support housing 178; a releasable rim assembly 180 pivotally connected to the main support housing 178; and an actuator latch assembly 182 connected to the releasable rim assembly 180 and the main support housing 178.
The main support housing 178 includes a base plate 183 having rim support lugs 184 at upper, outer edges of the base plate 183 and spring support lugs 186 at lower, outer edges of the base plate 183. The base plate 183 has a plurality of holes 187 to receive the nut and bolt members 18 to anchor same to the backboard member 14. Each of the lugs 184 and 186 are provided with holes 188 for reasons to be explained.
The releasable rim assembly 180 includes the conventional rim member 190 having an inner edge secured to a connector housing 192 and a half portion is secured to a connector rim 193. the connector housing 192 includes a pair of parallel anchor plates 194; a top plate 196 secured to the anchor plates 194; and an anchor shaft 198. The anchor plates 194 are provided with aligned holes 200 to receive the anchor shaft 198 therethrough. The stop plate 196 abutts the rim support lugs 184 when in the usage position to limit rotation in the direction as indicated by an arrow 201. The anchor shaft 198 is also mounted in the holes 188 of the rim support lugs 184 and held against axial movement by cotter pins 203.
The connector rim 193 is secured to a bottom surface 204 of the rim member 190 and provides rigidity thereto. Opposed end portions 206 of the connector rim 193 are provided with holes 207 to be used in connecting to the actuator latch assembly 182.
The actuator latch assembly 182 includes a pair of compression spring assemblies 208 mounted on opposed sides of the rim member 190. Each spring assembly 208 resembles a shock absorber having a cylinder end 210; a piston and rod member 212 mounted in the cylinder end 210; and a compression spring member 214 mounted about the piston and rod member 212. Also, opposite ends of each spring assembly 208 is formed with a connector lug 215 usable with a nut and bolt member 217 for securing to respective spring support lugs 186 and the end portions 206 of the connector rim 193.
USE AND OPERATION
In the use and operation of the compression latch goal assembly 176, the base plate 183 is secured against the backboard member 14 with the nut and bolt members 18. The compression spring assemblies 208 act to hold the rim member 190 in the horizontal, usage position.
On application of downward pressure on an outer portion of the rimmember 190, it is obvious that each spring member 124 is compressed similar to the action of a shock absorber. The rim member 190 pivots about the anchor shaft 198 toward a downwardly inclined position.
On release of the rim member 190, it is obvious that the compressed spring members 214 moves the rim member 190 upwardly. The stop plate 196 contacts the top surface of the base plate 183 of the support housing 178 to position the rim member 190 automatically in the horizontally, usage position.
Central Pivot Latch Goal Assembly Embodiment
As collectively shown in FIGS. 8 and 9, a central pivot latch assembly, indicated generally at 218, is shown as secured to the backboard member 14 by the nut and bolt members 18. More particularly, the central pivot latch goal assembly 218 includes a main support housing 220; a releasable rim assembly 222 pivotally connected to the main support housing 220; and an actuator latch assembly 224 connected to the releasable rim assembly 222 and the main support housing 220.
The main support housing 220 includes a base plate 226 and a pair of rim support arms 228 connected to the base plate 226. The base plate 226 is of rectangular shape and has a plurality of holes 230 to receive the nut and bolt members 18 to anchor same to the backboard member 14.
Each rim support arm 228 includes a support plate 231 having an edge 232 secured to the base plate 226 and another edge 234 integral with a curved rim support member 236. The outer end of each rim support member 236 is formed with a flat surface 238 and a central hole 239 for reasons to be explained.
The releasable rim assembly 222 includes a conventional rim member 240 having a latch or connector shaft 242 secured by lug members 244 to the area adjacent the backboard member 14, a stop member 246 secured to the rim member 240, and a connector assembly 248 to pivotally connect the rimmember 240 to the rim support member 236.
The connector assembly 248 includes a main body 250 connected to a lower surface of the rim member (on each side); a nut, bolt, and washer member 252 inserted through the central hole 239 and a hole 253 in the main body 250, and a friction pad 255 mounted between the flat surface 238 and the main body 250.
The nut, bolt, and washer member 252 is adjustable to regulate the force needed to tilt the rim member 240 due to the areas of frictional contact.
The actuator latch assembly 224 is an option with this embodiment and provides an additional latching means for the releasable rim assembly 222. In fact, the actuator latch assembly 224 is substantially identical to that of FIGS. 1, 2, and 3 having the latch support base assembly 62; a pair of actuator arms 64 pivotally connected to the latch support base assembly 62; and a biasing assembly 66 operably connected to the actuator arms 64. The actuator arms 64 grasp onto the latch connector shaft 242 in the horizontal usage position. Further discussion of this latch mechanism is not deemed necessary as operates identical tot he actuator latch assembly 22 set forth in the first described embodiment.
USE AND OPERATION
In the use and operation of the central pivot latch goal assembly 218, the base plate 226 is connected to the backboard member 14 with the nut and bolt members 18 in a conventional manner.
In the horizontal usage position, it is held as shown in FIG. 9 by both (1) the friction connection with the friction pad 225; and (2) the actuator latch assembly 224 with either (1) or (2) sufficient but superior latching is achieved by the combinations of (1) and (2).
On application of downward pressure on an outer portion of the rim member 240, the actuator latch assembly 224 releases in a manner identical to that shown in FIG. 2. The rim member 240 moves to the positon shown in dotted lines in FIG. 8. The rim member 240 is reset by moving to a horizontal position and the actuator amrs 64 grasp the latch actuator shaft 242 and the stop member 246 contacts upper surfaces of respective ones of the main body 250 of the connector assembly 248.
Compression Tube Latch Goal Assembly Embodiment
As shown in FIG. 10, a compression tube latch goal assembly, indicated generally at 256, includes a support housing 258 secured to the backboard member 14; a releasable rim assembly 260 connected to the support housing 258; and an actuator latch assembly 262 connected to the support housing 258 and the releasable rim assembly 260.
The support housing 258 includes a base plate 264 and a pair of spaced, parallel, support lugs 266 secured to the base plate 264. The base plate 264 is formed with spaced holes 267 to receive a portion of the actuator latch assembly 262 therethrough as will be explained. Also, the backboard member 14 is formed with spaced slots 268 adjacent the respective holes 267.
The releasable rim assembly 260 includes a conventional rim member 270 having a stop plate 272 secured to a top surface 274 and a connector rim 276 secured to opposite lower edges of the rim member 270.

The actuator latch assembly 262 has a pair of biasing members 284 (one at each side of the rim member 270) similar to that shown in FIG. 7 although only one is clearly visible in FIG. 10. Each biasing member 284 includes a housing tube 286 with a compression spring member 288 therein.
A lower end of the housng tube 186 is pivotally connected to a support member 290 which is connected to a support member 290 which is connected to the base plate 264. An upper end of the housing tube 286 is pivotally connected to the bolt member 283 so that the housing tube 286 is movable toward the position shown in dotted lines in FIG. 10. A lower end of the compression spring member 288 contacts the stationary support member 290.
USE AND OPERATION
In the use and operation of the compression tube latch goal assembly 256, the backboard member 14 has to come with the slots 268 therein or specially cut out for mounting. The compression spring member 288 acts between the support member 290 and the upper end of the housing tube 286 to hold the rim member 270 in the horizontal, usage position as shown in FIG. 10. The stop plate 272 limits upward movement about the connector shaft 280.
On downward pressure on the rim member 270, the spring member 288 is compressed and the rim member 270 moves to the position as shown in dotted lines in FIG. 10. Obviously, on release of subject downward pressure, the compression spring members 288 automatically moves the rim member 270 back to the normal, horizontal, usage position.
