the standard 10 of the present invention is generally depicted in fig1 and in fig6 a - 6c as the same might be used to support a game net 12 . however , it is contemplated that the standard 10 could be used in several different applications , including , but not limited to , supporting a flag , a banner , or even serving as a simple microphone stand . for ease of description herein , the same will be described simply as it could be used for supporting a game net 12 above a playing surface 14 . the standard 10 is generally comprised of at least an elongated net support 16 having an upper end 18 and a lower end portion 20 . a net tensioning system 22 , which is depicted in fig1 and 2 , is preferably secured within the interior portion of the net support 16 . the net tensioning system 22 is preferably provided with an elongated tensioning screw 24 having mating threads disposed along its length . the tensioning screw 24 is generally coaxially disposed within the outer tube 26 of the net tensioning system 22 . the tensioning screw 24 is rotatably supported within the tube 26 at its opposite ends using a first bearing assembly 28 and a second bearing assembly 30 . a gear box 32 is disposed adjacent the second bearing assembly 30 . the gear box 32 is preferably comprised of a drive shaft assembly 34 which is received by a first miter gear 36 . the first miter gear 36 is meshed with a perpendicularly disposed second miter gear 38 which is coupled with the tensioning screw 24 . accordingly , as the drive shaft assembly 34 is rotated , the first and second miter gears cooperate to rotate the tensioning screw 24 . a crank handle 40 , or similarly operating manual or automatically powered device , is removably engaged with the drive shaft assembly 34 . accordingly , as the crank handle 40 is rotated , the gear box assembly 32 operates to rotate the tensioning screw 24 . a tensioning nut 42 is threadably received by the tensioning screw 24 within the tube 26 . accordingly , as the tensioning screw 24 is rotated , the tensioning nut 42 is moved along the length of the tensioning screw 24 . it is contemplated that the net tensioning system could be comprised of a worm gear drive assembly in place of the tensioning screw 24 , gear box 32 and tensioning nut 42 . an example of such a worm gear drive assembly is depicted in fig7 . the worm gear drive assembly is preferably provided with a drive shaft 112 having a drive gear 114 which cooperates with a worm gear 116 to rotate a mating gear assembly 118 . the mating gear assembly is preferably provided with a strap shaft 120 , on which the tensioning line 44 could be wound and unwound to apply tension to the net 12 . the tensioning nut 42 is preferably coupled to the net 12 via a tensioning line 44 . it is contemplated , however , that the tensioning line 44 could simply be replaced using an elongated free end of the upper line extending from the net 12 . the tensioning line 44 is preferably coupled with the net using a hook 46 or similar structure that provides quick and easy engagement with the upper portion of the net 12 . the tensioning line 44 enters the tensioning system 22 and is preferably engaged first by the roller guide 48 and then a plurality of bushings 50 , which guide the tensioning strap 44 to the tensioning nut bushing 52 and up to an anchor 54 . accordingly , it can be seen in fig2 that as the tensioning nut 42 is advanced and retracted along the length of the tensioning screw 24 , the tensioning line 44 is withdrawn and extended from the tensioning system 22 to adjust the tension applied to the net 12 as desired . although it is contemplated that a second net tensioning system 22 could be disposed within the opposing standard supporting the net 12 , it is also contemplated that a fixed tensioning strap assembly could also be provided in its place . the net support 16 is preferably telescopically received within and extended from a lower support 56 , having an upper end 58 and a lower end portion 60 . a stop collar 61 is preferably secured within the upper end 58 of the lower support 56 that is sized to slide along the length of the net support 16 until meeting the enlarged stop 63 at the lower end portion 20 of the net support 16 . in this manner , the net support 16 is prevented from complete withdrawal from within the lower support 56 . the lower support 56 is telescopically received within and selectively extendable from an elongated housing 62 , having an upper end portion 64 and a lower end portion 66 . a base assembly 68 is preferably positioned adjacent the upper end portion 64 of the housing 66 and generally flush with the playing surface 14 . a cover 70 is provided for covering the base assembly 68 ( as depicted in fig4 ) when the standard 10 is fully retracted beneath the playing surface 14 . in this manner , a generally uniform playing surface 14 is provided that will not interfere with alternate uses of the playing surface 14 . the base assembly 68 is generally provided with a locking lug 72 which is slidably mounted within the base assembly 68 to move perpendicularly toward and away from the standard 10 . a spring 74 can be provided to bias the locking lug 72 toward the standard 10 . a locking lever 76 is pivotably coupled with the base assembly 68 to selectively engage an activator plate 78 to which the locking lug 72 is secured . accordingly , activation of the locking lever 76 to engage the activator plate 78 will move the locking lug 72 away from the standard 10 , allowing the same to extend from or retract within the housing 62 . a plurality of height adjustment stops 80 are disposed along the length of the outer surface of the lower support 56 . although the height adjustment stops 80 are depicted as a collar having an engagement edge 82 , it is only necessary to provide sufficient structure to engage the locking lug 72 so that retraction of the standard 10 inot the housing 62 is prevented . in the embodiment depicted in fig1 , guide collars 84 and 86 are provided to help stabilize the lower support 56 within the housing 62 . where collars or similar structures are used as the height adjustment stops 80 , it is preferred that the edge portions 83 that do not engage the locking lug 72 be beveled , as indicated in fig1 , to permit the smooth passage of the locking lug 72 . it is preferred that the positioning of the height adjustment stops 80 along the length of the lower support 56 coordinate with one or more pre - selected height adjustments for the standard 10 . for example , fig6 a depicts the standard 10 as it could be used to support the game net 12 at a height suitable for use in an adult volleyball game . this position is attained by the engagement of the locking lug 72 beneath the engagement edge 82 of the lowermost height adjustment stop 80 on the lower support 56 . fig6 b depicts the standard 10 as supporting the net 12 at a height suitable for playing tennis . this position is attained by engaging the locking lug 72 with the engagement edge 82 of the uppermost height adjustment stop 80 on the lower support 56 . likewise , fig6 c depicts the standard 10 as the same could be positioned at a height intermediate the “ volleyball ” height of fig6 a and the “ tennis ” height of fig6 b , so that a youth league could play volleyball or some other sport . a plunger assembly 88 is preferably disposed within the net support 16 , adjacent the net tensioning system 22 . the plunger assembly 88 is generally provided with a plunger 90 that is biased outwardly from the plunger assembly 88 using a spring or other similar structure . the plunger 90 is first positioned to extend outwardly from an opening 92 in the side of the net support 16 . the plunger 90 remains in this retracted state until the net support 16 is extended from within the lower support 56 a sufficient distance for the plunger 90 to pass the upper end portion 58 of the lower support 56 . as the plunger 90 passes that point , it fully extends to provide a positive stop , preventing the net support 16 from retracting within the lower support 56 at an undesirable time . the plunger 90 can be selectively moved to its retracted position by either manually depressing the same or by depressing a pin 94 that is operatively engaged with the plunger 90 using a bell crank or similar device . although it is contemplated that the standard 10 could be manually extended from and retracted within the housing 62 , it is preferred that power cylinder mechanics such as a pneumatic or hydraulic system be employed to automate the same . preferably , a pneumatic line 96 would be disposed between a pneumatic coupler 98 at the base assembly 68 and a fitting 100 at the lower end portion 66 of the housing 62 . it is contemplated , however , that the pneumatic line 96 could be coupled directly to a remote pneumatic source via lines that run away from the standard 10 beneath the playing surface 14 . with the pneumatic source being coupled to the lower end portion 66 of the housing 62 , piston seals 102 and 104 are coupled to the lower end portions 60 and 20 of the lower support 56 and the net support 16 , respectively . it is preferred that the piston seal 102 be positioned to be in engagement with the inner surface of the housing 62 ( and likewise that the piston seal 104 be placed in engagement with the inner surface of the lower support 56 ) to properly seal the openings of the system . accordingly , as pneumatic ( or hydraulic , when desired ) pressure is applied to the system , the net support 16 will extend from the lower support 56 , which will extend from the housing 62 . once the standard 10 is at full extension , the addition of pneumatic pressure can be stopped . the user may then slowly release the pneumatic pressure until the lower support 56 is positioned adjacent the locking lug 72 at the desired height , in which the locking lug 72 is allowed to engage the recess 86 or other provided structure to support the standard 10 in position . when it is desired to store the standard 10 , the user simply disengages the locking lug 72 with the locking lever 76 and further retracts the plunger 90 within the net support 16 . the remaining pneumatic pressure can then be slowly released , permitting the lower support 56 to retract within the housing 62 and the net support 16 to retract within the lower support 56 . resilient bumper members 105 can be disposed onto the lower end portions 20 and 60 of the net support 16 and lower support 56 to help cushion the controlled retraction of the standard 10 . with the standard 10 being fully retracted beneath the playing surface 14 , the locking lever 76 can be disengaged , allowing the locking lug 72 to position itself forwardly , just above the upper end portion 18 of the net support 16 , thus preventing its unintended extension of the standard 10 beyond the base assembly 68 . when the user has fully extended the standard 10 so that it is at the desired playing height with respect to the playing surface 14 , the user may then couple the upper end portion of the net 12 to the hook 46 of the net tensioning system 22 . this is then performed on the opposite side of the net to the accompanying net standard . the user disposes the crank handle 40 within the gear box 32 and rotates the crank handle 40 until the proper amount of tension has been placed on the upper end portion of the net 12 . it is contemplated that the line extending through the lower end portion of the net 12 could simply be tied to the net support 16 to secure the same in place . however , it is preferred that a supplementary net tensioning system 106 , similar to that depicted in fig5 , be provided . the supplementary net tensioning system 106 is preferably provided with a line winch 108 and a pair of shaped engagement members 110 . keyholes 112 or similar shape of securement opening are preferably formed in the net support 16 to receive the shaped engagement members 110 therein . once the line is secured , the line winch 108 can be actuated until the lower net line is properly tensioned and secured . the hook 46 and net tensioning system 106 provide a fast and easy means for coupling the net 12 to the standard 10 . they further provide a convenient means for keeping a majority of the net mounting components with the net during storage . it is contemplated that where high degrees of tension are put on the upper and / or lower end portions of the net , the standard 10 may bend slightly in the direction of the net . in order to compensate for this , it is contemplated that the standard 10 could be formed from a reinforced material that would naturally resist the tensioning forces . however , a more economical approach will simply be to use floor ring spacers to pitch the housing 62 and the standard 10 at an angle of only a few degrees so that when the two standards are disposed above the playing surface 14 , they are slightly angled away from one another . then , as the tension is applied to the net 12 , the standards will be brought to their generally perpendicularly oriented position with respect to the playing surface . in the drawings and in the specification , there have been set forth preferred embodiments of the invention ; and although specific items are employed , these are used in a generic and descriptive sense only and not for purposes of limitation . changes in the form and proportion of parts , as well as substitution of equivalents , are contemplated as circumstances may suggest or render expedient without departing from the spirit or scope of the invention as further defined in the following claims . thus it can be seen that the invention accomplishes at least all of its stated objectives .
a standard for supporting a game net above a playing surface is provided with an internal net tensioning system which allows the standard to be stored beneath the playing surface . a plurality of pre - set height stops are provided along the length of the standard to allow the net to be set at one of several different heights to accommodate the playing of different games by different playing abilities . power cylinder mechanics permits the automatic raising and lowering of the standard with respect to the playing surface . a quick attachment system is provided for quickly and easily engaging and disengaging the net from the standard .
