limiting exemplary embodiment of scooter 10 , such as that illustrated in fig1 c and 1d , first latching bracket 26 is a clip . turning now to fig1 a , 1 b , 1 e and 1 f , rear wheel axle 66 is illustrated coupling together several components of scooter 10 at rear section 44 of deck 20 . in a non - limiting exemplary embodiment of scooter 10 , moving outwards in either direction from rear wheel 18 , these components include second latching brackets 28 , opposing sides 47 ( only one shown ) of a rear wheel fork defined at least in part by opposed walls 46 of deck 20 , and second ends 60 and 62 of respective frame members 52 and 54 of backpack stand 24 . rear wheel 18 is coupled in a configuration enabling rotational movement thereof about rear wheel axle 66 . each second latching bracket 28 includes shallow channel or trough 68 configured for removably receiving and retaining ( e . g ., securing , engaging ), when backpack stand 24 is in an unstowed ( e . g ., an extended ) position , at least a portion of each frame member 52 / 54 . second ends 60 and 62 of respective frame members 52 and 54 of backpack stand 24 are coupled in a configuration enabling rotational movement of frame members 52 and 54 about rear wheel axle 66 . it should be understood that the illustrated configuration or order in which the components are coupled is only for the purpose of describing a non - limiting exemplary embodiment of scooter 10 . for instance , second latching brackets 28 are illustrated with their respective shallow channels 68 facing outwards in opposite directions and away from rear wheel 18 . additionally , the rotatably coupled frame members 52 and 54 are illustrated facing or on the same side as the shallow channels of second latching brackets 28 . as such , frame members 52 and 54 will be received within and removably secured or engaged in shallow channels 68 when backpack stand 24 is rotated from a stowed position to an unstowed position . alternate configurations for the one or more components and / or the order in which they are arranged and coupled will become apparent to one skilled in the art . all such alternate embodiments are considered as being within the metes and bounds of the instant invention . in a non - limiting exemplary embodiment of scooter 10 , backpack stand 24 includes indentations 70 and 72 , respectively , on at least a portion of frame members 52 and 54 . as perhaps best illustrated with reference to fig1 g - 1i , indentations 70 and 72 in combination with spacer 64 are configured for receiving and retaining at least a portion of backpack 74 . backpack 74 , in a non - limiting exemplary embodiment , includes latching hook 76 and latching bar 78 for removably affixing or securing backpack 74 to backpack stand 24 of scooter 10 . as described herein below with reference to an embodiment for a method of use , spacer 64 , indentations 70 and 72 , latching hook 76 and latching bar 78 are used in combination for removably attaching or securing backpack 74 to scooter 10 . a non - limiting exemplary embodiment of a method of using scooter 10 includes one or more of the following steps starting from backpack stand 24 in a stowed position with spacer 64 engaged in first latching bracket 26 . spacer 64 , to which first ends 56 and 58 frame members 52 and 54 are fixedly attached , is disengaged from first latching bracket 26 and lifted away from deck 20 of scooter 10 . accordingly , frame members 52 and 54 will rotate about rear wheel axle 66 to which second ends 60 and 62 are rotatably coupled . the lifting of spacer 64 and rotation of frame members 52 and 54 is continued until at least portions thereof are received and engaged within shallow channel 68 of each second latching bracket 28 . backpack stand 24 is now considered ready for use and backpack 74 is removably attached to spacer 64 and indentations 70 and 72 . as shown by the direction of arrow 80 , latching hook or clip 76 is placed on or positioned over spacer 64 and rotatably hooked or clipped thereto such that spacer 64 provides a pivoting configuration about which backpack 74 can be rotated . next , latching bar 78 is removably secured ( or latched or clipped ) within indentations 70 and 72 in respective frame members 52 and 54 by swinging the bottom of backpack 74 , to which latching bar 78 is fixedly attached , towards backpack stand 24 in the direction indicated by arrow 82 . as illustrated in fig1 i , scooter 10 having backpack 74 attached thereto is ready for use . it will be apparent that the process is reversed for detaching backpack 74 from scooter 10 . in a non - limiting exemplary embodiment , latching bar 78 is rotatably attached to backpack 74 which includes storage compartment 84 for at least partially stowing latching bar 78 after backpack 74 has been detached from backpack stand 24 of scooter 10 . as illustrated in fig1 j , at least a portion of latching bar 78 can be stowed within storage compartment 84 by moving it in the direction indicated by arrow 86 . flap 88 can then be used to cover up latching bar 78 stowed within storage compartment 84 . after backpack 74 has been separated from scooter 10 , backpack stand 24 can be returned to the stowed position by reversing the order of the steps for extending or opening backpack stand 24 . in a non - limiting exemplary embodiment , latching hook or clip 74 may be configured as a telescoping ( or extendible ) handle which can be extended when attached to and / or when detached from backpack stand 24 . because the distance between spacer 64 ( or first ends 56 and 58 ) and indentations 70 and 72 is essentially fixed by design or manufacture , a telescoping latching hook 76 enables attaching backpacks of different sizes ( or heights ) to scooter 10 . for instance , latching hook 76 can be extended towards or away from backpack 74 such that the distance between latching hook 76 and latching bar 78 is appropriate for attaching or securing backpack 74 to spacer 64 and indentations 70 and 72 of scooter 10 . in certain embodiments , latching bar 78 includes one or more rotatably mounted wheels configured for rolling backpack 74 along a surface . for instance , after backpack 74 has been detached from scooter 10 , latching hook 76 can be extended away from ( or towards ) backpack 74 and the one or more wheels of latching bar 78 can be used for rolling , e . g ., pulling and / or pushing , backpack 74 . fig2 a illustrates an embodiment of brake 30 in a disengaged position over rear wheel 18 , and fig2 b illustrates brake 30 engaging rear wheel 18 . brake 30 includes a pair of opposed side walls 102 ( only one shown ) extending between top and bottom arcuate walls 104 and 106 . at least a portion of top arcuate wall 104 extends through opening 108 in at least a portion of rear section 44 of deck 20 . brake 30 is positioned over at least a portion of rear wheel 18 and is coupled to deck 20 by coupling 110 . in a non - limiting exemplary embodiment , such as that illustrated in fig2 c , brake 30 includes one or more spring - biased mechanisms 112 configured for retaining brake 30 in the disengaged position while not in use as shown in fig2 a . during normal operation , brake 30 is in a disengaged position and bottom arcuate wall 106 does not contact rear wheel 18 . when brake 30 is used , for example while rear wheel 18 is rotating , pressure is applied on top arcuate wall 104 whereby bottom arcuate wall 106 moves towards , and contacts , rear wheel 18 . bottom arcuate wall 106 engages or applies pressure on rear wheel 18 to inhibit or stop its rotational movement . when the pressure applied on top arcuate wall 104 is removed , bottom arcuate wall 106 moves away from rear wheel 18 , thereby disengaging brake 30 . accordingly , in certain non - limiting exemplary embodiments , one or more spring - biased mechanisms 112 for brake 30 includes one or more torsion springs , one or more compression springs , one or more expansion springs , one or more pairs of opposed levers , or any other spring - biased mechanism configured for retaining brake 30 away from rear wheel 18 in the absence of external forces on any portion of brake 30 . fig3 a and 3b are perspective views of an embodiment of scooter 150 illustrated in an extended or open or unfolded position such as when in use , and fig3 c and 3d are perspective views of scooter 150 in a collapsed or folded position such as when not in use . while the shapes of some components or elements differ somewhat , several aspects of scooters 10 and 150 are similar . accordingly , like numerals reference like elements . as can be seen , scooter 150 , in contrast to scooter 10 , does not include backpack stand 24 , and therefore also does not include first and second latching brackets 26 and 28 . also as can be seen , scooter 150 is configured for being folded or collapsed when not in use . this functionality is enabled by using couplings 152 and 154 , respectively , instead of couplings 48 and 50 of scooter 10 . in accordance with an embodiment of the invention , couplings 152 and 154 each include one or more locking or latching mechanism configured for retaining scooter 150 in the extended ( open or unfolded ) or collapsed ( folded ) position . the mechanism must then be unlocked or unlatched for changing the configuration of scooter 150 . for instance , coupling 152 is configured such that by rotating steering column support frame 14 and deck support frame 158 apart or away from each other , the locking or latching mechanism is activating when they reach a predetermined position relative to one another . the locking or latching mechanism must then be deactivated for rotation in the opposite direction . this can be accomplished , for instance , by pushing in the ends of the coupling towards one another while rotating steering column support frame 14 and deck support frame 158 towards one another . coupling 154 is similarly configured . fig3 c and 3d also partially illustrate channel or open - ended trough 156 on bottom surface 40 under deck 20 . as previously described in reference to fig1 a and 1b , trough 156 extends longitudinally between front and rear section 42 and 44 , respectively , of deck 20 and is at least partially defined by a pair of opposed walls 46 extending away from bottom surface 40 . channel or open - ended trough 156 is at least partially configured for receiving at least a portion of deck support frame 158 . fig4 a and 4b are perspective views of an embodiment of scooter 200 illustrated in an extended or open or unfolded position such as when in use , and fig4 c and 4d are perspective views of scooter 200 in a collapsed or folded position such as when not in use . again , while the shapes of some components or elements differ somewhat , several aspects of scooters 10 , 150 and 200 are similar . accordingly , like numerals reference like elements . for instance , scooters 10 , 150 and 200 include the same or similar handlebar 32 , front and rear wheels 16 and 18 , etc . however , as illustrated , the following components of scooter 200 differ somewhat from the corresponding components in scooter 10 and / or scooter 150 : steering column support frame 202 , deck support frame 204 , deck 206 , coupling 208 , and steering column 214 . in contrast to couplings 48 and 152 , at least coupling 208 is different in that it is a pivoting point and not a locking or latching coupling such as couplings 48 and 152 . in scooter 200 , the locking or latching functionality for steering column support frame 202 and deck support frame 204 is configured as a spring - loaded latch including receptacle 210 and pin 212 . as illustrated , coupling 212 rests within receptacle 210 when scooter 200 is in the open or unfolded position . accordingly , when folding scooter 200 , coupling 212 is retracted from receptacle 210 while steering column support frame 202 and deck support frame 204 are rotated towards one another . fig5 a is a side view of another embodiment of scooter 250 illustrated in an extended or open or unfolded position such as when in use , and fig5 b and 5c are perspective views of scooter 250 in a collapsed or folded position such as when not in use . again , while the shapes of some components or elements differ somewhat , several aspects of scooters 10 , 150 , 200 and 250 are similar . accordingly , like numerals reference like elements . for instance , all embodiments of the scooter include the same or similar handlebar 32 , front and rear wheels 16 and 18 , etc . however , as illustrated , the following components of scooter 250 differ somewhat from the corresponding components in other embodiments of the scooter : steering column 252 , steering column support frame 254 , deck support frame 256 , deck 258 , and coupling 260 . while coupling 260 appears different from coupling 48 , it is configured to function in substantially the same manner , i . e ., coupling 260 also includes a locking or latching mechanism the same as or similar to that of coupling 48 . fig6 a and 6b , respectively , are perspective views of an embodiment of scooter 300 with backpack stand 302 in a stowed position and an unstowed position . in contrast to backpack stand 24 , backpack stand 302 is defined at least in part by elongated member 304 extending between first end 306 and securement fork 308 at second end 310 opposite first end 306 . as illustrated , at least a portion of securement fork 308 extends through opening 312 in rear section 44 of deck 314 and is rotatably coupled to rear wheel axle 66 . top surface 316 of deck 314 includes longitudinally extending groove 318 configured , at least in part , for removably receiving and retaining backpack stand 302 in the stowed position . as illustrated in fig6 b and 6c , first end 306 of backpack stand 302 includes carabiner 320 for removably receiving and retaining at least a portion of backpack 74 . in view of the incorporated illustrations and description of certain non - limiting exemplary embodiments of the instant invention , various modifications thereof and / or alternate embodiments may become apparent without departing from the spirit , scope and intent of the invention . for instance , while the illustrated and / or described embodiments refer to particular features and / or functions , the invention is considered to also include embodiments having combinations of features and / or functions different from those described . accordingly , the scope and intent of the invention is intended to embrace all alternatives , modifications , variations , etc ., as may become apparent to one skilled in the art .
