fig1 - 11 illustrate the preferred embodiments of the present invention . in the following discussion of the presently preferred embodiments , like reference numerals refer to like elements . further , the following discussion is not to be considered in a limiting sense . rather , while the following discussion taken in conjunction with the drawings illustrate the presently preferred embodiments of the present invention , the invention is in no way limited to the embodiments described below and shown in the drawings . it is to be understood that numerous modifications , additions and / or substitutions can be made to the preferred embodiments without departing from the spirit and scope of the present invention . fig1 - 3 illustrate a first embodiment of the present invention . as seen therein , an in - line skate 10 can include an upper 12 , an outer sole 14 and a wheel attachment member 16 . the wheels 20 are supported by a wheel support member 18 that may be attached to the wheel attachment member 16 . as seen in fig4 the wheel support member typically is positioned on both sides of the wheels 20 , however it is seen on a single side of the wheels 20 in fig1 for purposes of illustrating the wheel disabling mechanism of the present invention . the wheel disabling mechanism 22 includes a switch support member 21 mounted rearward of the heel of the skate . a switch member 23 is pivotally attached to the switch support member 21 through a hinge mechanism 230 . any suitable hinge mechanism may be utilized with the present invention . of course , those skilled in the art will readily recognize that it may be possible to utilize other forms of switches with the present invention . for example , a sliding switch member , a turning switch member , or a pulling switch member may also be utilized with out departing from the spirit of the present invention . the switch member 23 is attached to a cable 24 . the cable 24 is preferably formed of steel , although any sufficiently strong material may be utilized . the cable 24 is connected to a series of clamping members 26 which preferably extend downward from the wheel attachment member along both sides of the wheels 20 . the clamping members 26 , which are essentially braking mechanisms utilized on bicycles and adapted for use on the in - line skate seen in fig1 preferably include a pair of arms for each wheel . each of the clamping members 26 has frictional pads 28 positioned at the ends thereof to make frictional contact with the wheels 20 . the wheels 20 , which may be supported on hubs 34 through which pass the axles 32 , are typically made of plastic , rubber , polyurethane , or some other suitable material . the length of the clamping members is such that the frictional pads 28 clamp the sides of the wheels 20 at a point that provides a secure frictional contact between the pads 28 and wheels 20 . as seen in fig1 and 2 , the contact position between the pads 28 and the wheels 20 may be midway between the hub 34 and the outer diameter edge of the wheel . however , any suitable position on the wheel surface that enables a frictional force sufficient to secure the wheel and preclude the wheel from rotating may be utilized . as seen in detail in fig2 the pad 28 may be formed of two parts , 280 and 282 . the two parts include a resilient frictional pad 280 that contacts the wheel surface and a pad support 282 which may be metal , plastic , nylon , or some other sufficiently strong material to support the pad 280 . the two parts , 280 and 282 may be glued together or held together using the bolt 284 used to support the pad 28 at the end of the clamping arm 26 . alternatively , the pad support 282 may be formed internal to the pad 280 , or may be eliminated altogether depending the material of the pad 280 . the frictional pad 280 may be made of the same material as the wheel 20 or some other material capable of producing a sufficient frictional force when pressed against the wheel 20 to prevent the wheel from rotating . the clamping members 26 are preferable supported in place above the wheels by a flange 36 , through which a bolt 38 passes through the surface 40 . a nut 39 may be provided to secure the bolt 38 . the flange 36 is sufficiently strong to support the clamping members 26 securely when the clamping members are being used to clamp the wheels 20 . the flange 36 may be secured to the wheel attachment member 16 or alternatively may be secured to the upper portion of the wheel support member 18 . as those skilled in the art will appreciate , by utilizing a mechanism substantially identical to a bicycle braking mechanism , the clamping members 26 are spring biased away from the sides of the wheels 20 in normal skating conditions , in the same manner that bicycle brakes are biased away from the wheel of a bicycle when the rider is riding . the cable 24 may be used to overcome the spring bias and force the clamping members 26 in toward the wheels 20 , thus causing the wheels 20 to be securely held . as seen in fig2 a roller bearing 42 may be provided on an axle 44 to assist in controlling the position of the cable 24 as it approaches the clamping members 26 . as seen in fig3 the cable 24 passes through the switch support member 21 ( as seen by dashed line 240 ) and connects to the switch member 23 at position 244 . in operation , the switch 23 may be rotated on hinge 230 in the direction of arrow 25 during normal skating . this releases tension on cable 24 , thus allowing the frictional pads 28 to be spaced from the surface of the wheels 20 . to secure the wheels 20 , thus enabling the wearer to walk in the skate without the wheels turning , the switch 23 is pivoted in the direction opposite to arrow 25 . this introduces tension on the cable 24 , causing it to move in the direction of arrow 27 . this , in turn , causes the clamping members 26 to move inward , causing contact to be made by between the wheel 20 and the frictional pads 28 . the operation is substantially similar to the operation of brakes on a bicycle , however the switch member 23 is held securely in the switch support member 21 to keep tension on the cable 24 and thus keep the frictional pads in contact with the wheels 20 . a relief 210 is provided in the switch support member to assist the wearing in removing the switch 23 from the support member 21 , thus allowing the frictional pads to be released from contact with the wheels 20 . the position 244 at which the cable 24 connects to switch 23 may be adjusted in order to adjust the amount of tension placed on the cable 24 . in addition , while a single cable may be utilized between the switch 23 and the clamping members 26 , it is also possible to utilize multiple cables . fig4 - 6 illustrate another embodiment of the present invention . as illustrated herein , the in - line skate 10 is provided with a pair of arc shaped walking members 50 , preferably having a resilient portion 52 formed at the lower surface thereof to provide proper friction for walking on the ground as well as for securing the lower edge of the walking members 50 against the side of the wheels 20 . in this embodiment , a pair of walking members 50 is provided . it should be understood that both walking members include the features described here . the walking members 50 are slidably secured to the upper 12 through a pair of channels 56 . as seen in fig4 a , a pair of t - shaped retaining members 51 protrudes from the inner wall surface of the walking member 50 and is used to prevent the walking members from disengaging from the channels 56 . those skilled in the art will readily appreciate that any suitable retaining member may be utilized , including , but not limited to , screws , bolts , plastic molded plugs or any other suitable member . a locking member 54 is also provided to secure the walking member in the upper position ( seen in fig4 ) and the lower position seen in fig5 and 6 . the locking member 54 includes a locking arm 540 having a hook - shaped distal end 542 . the locking member 54 is biased via spring 544 toward the upper 12 of the in - line skate 10 . the button 545 is used to overcome the spring force and remove the distal end 542 of the locking 540 from one of two recesses 53 formed in the upper 12 . the recesses 53 include additional space 546 therein to allow the locking member 54 to move upward to disengage the hook - shaped distal end 542 from the recess 53 . the locking member is then pulled outward from the recess 53 , and a relief 548 is provided to partially accommodate the hook - shaped member . in operation , when the wearer of the in - line skate 10 wishes to disable the wheels 20 , the locking member 54 is pushed slightly upward and then pulled outward to release the locking arm 540 from the recess 53 . once the locking arm is pulled from the recess 53 , the walking member 20 is then slid in a downward direction as seen by directional arrow 55 . when the walking member reaches the lower position , the locking arm 540 engages the lower recess 53 , and the walking member locks in place . the lower recess is positioned such that the resilient portion 58 on the lower edges of the walking member 50 presses against the sides of the wheels 20 so as to prevent the wheels 20 from rotating . thus , the wheels of the skate are essentially disabled , thus allowing the wearer of the in - line skate to safely walk without fear of the wheels slipping out from under them . a further embodiment of the present invention is seen in fig7 - 9 . in this embodiment , a pair of walking members 60 are secured by a pair of hinges 66 to the upper surface 180 of the wheel support member 18 . the walking members include a flared portion 62 for improved stability when the wearer is walking . a resilient layer 64 is also provided along the edge of the flared portion 62 to provide improved stability when the wearer is walking . the resilient layer may be rubber , polyurethane , ethylene vinyl acetate ( eva ), or any other suitable material . a pair of resilient locking tabs 68 is cantilevered from the wheel support member 18 on each side of the in - line skate . the locking tabs are made from a resilient material such as plastic , that affords some spring - like tendencies such that the locking tabs 68 may be movable in direction of directional arrows 71 , 73 but tend to spring back to their original position . each locking tab includes a notch 70 for retaining the walking member 60 therein . in addition , the distal ends 69 of the locking tabs are tapered . in operation , when the in - line skater wishes to disable or otherwise prevent the wearer simply rotates the walking members about the hinge 66 . as the walking members engage the locking tabs 68 , the tapered ends 69 cause the locking tabs to spread in the direction of arrows 71 , 73 . once the walking members align with the notches 70 , the resilient nature of the locking tabs causes the tabs spring back to securely hold the walking members in the notches 70 . in this manner , the wearer may then walk on the skate without the wheels touching the ground . of course , the walking members may be any suitable length , and can be longer or short than that illustrated in fig7 - 9 . if longer , is possible to form an opening in the walking member to accommodate the locking tabs 68 such that the tabs pass through the opening but then operate in the identical manner to that discussed above . to return the walking member to the raised position , the wearer simply spreads the tabs 68 with their fingers , thus disengaging the walking members 60 from the notches 70 , and rotates the walking members 60 back to the upper position . as seen in fig8 and 9 , a pair of cantilevered fixing blocks 72 extends outward from the walking member 60 .. the blocks 72 each include a pair of rounded protrusions 76 formed thereon . the blocks 72 are received by receptacles 74 having detents 78 formed therein for receiving the protrusions 76 therein . in this manner , when the walking members 60 reach the raised position , the protrusions secure the walking members in the upright position in the detents 78 , thus keeping the walking members 60 in the raised position until lowered by the wearer . of course , any suitable fixing device may be utilized to secure the walking members in the upright position . for example , it may be possible to utilize bungee cords or some other hook mechanism fixed to the skate hasps 79 or the upper 12 which in turn connect to loops secured to the side of the walking members . any suitable device that prevents the walking members from falling while the wearer is skating may be utilized . for example , a modification to the embodiment of fig7 - 9 is seen in fig1 - 11 . as seen therein , the walking members 60 are provided with a spring hinge member 80 which is biased in the upward direction to hold the walking members 60 up when the wearer is skating . instead of the locking tabs 68 , this embodiment includes a sliding , spring loaded release mechanism 82 that , when operated , releases catch 84 from receptacle 86 . the spring loaded , sliding release mechanism 82 , together with the catch 84 and receptacle 86 is identical to locking mechanisms commonly found on luggage , brief cases , and other such items . in operation , the user simply slides the release mechanism 82 in the direction of arrow 89 . the spring hinge member 80 then rotates the walking member 60 using the bias force of the spring in the direction of arrow 87 . the user simply rotates the walking member 60 back down when seeking to avoid using the wheels 20 . the spring loaded release mechanism will cause the catch 84 to be secured in the receptacle 86 until the release mechanism 82 is again operated . in this embodiment , the flared portions of the walking members 60 can be shaped to press against the sides of the wheels 20 . in addition , it may be possible to include more than one release mechanism 82 . further , the spring hinge 80 may be any suitable spring mechanism , or may be replaced with the blocks 72 and receptacles 74 from the previous embodiment . of course , those skilled in the art will appreciate that the above - described embodiments of the present invention , while presently preferred by the inventor should be considered as illustrative of the numerous advantages of the present invention . the skilled artisan will readily realize that numerous modifications , substitutions , and additions may be made to the described embodiments . for example , it is clear that while the embodiments of fig4 - 11 show a pair of walking members for each skate , the present invention is not limited to a pair of walking members . it is possible that a single walking member could be provided for each skate or that more than two walking members could be provided for each skate . e . g ., it is possible that a pair of walking members could be provided for each wheel or for the forward or back wheels . it is intended that all such modifications , substitutions and additions fall within the scope of the present invention that is best defined by the claims appended hereto .
a device for disabling or otherwise allowing the wearer of an in - line skate to walk on the in - line skate without activating the wheels may include a clamping member to clamp the wheels . a switch may be activated which in turn activates or deactivates the clamping member . a walking member may also be provided , the walking member being coupled to the skate and moveable between first and second positions . in the first position the walking member may be secured such that the wearer may walk on the walking member . in the second position , the walking member is positioned such that it will not interfere when skating .
