although the invention has been described in terms of specific embodiments , it will be readily apparent to those skilled in this art that various modifications , rearrangements and substitutions can be made without departing from the spirit of the invention . the scope of the invention is defined by the claims appended hereto . now referring to fig1 and 2 , set forth is a perspective view of a skateboard 10 comprising an oblong platform 12 having a top surface 14 , a bottom surface 16 , a front end section 18 , and a tail end section 20 . a first pair of roller assemblies 22 mounted to the bottom surface 16 and proximate to the tail end section 20 operates with a second pair of roller assemblies 24 which are also mounted to the bottom surface 16 and located proximate to the front end section 18 . the use of a platform 12 and roller assemblies 22 , 24 ( wheels ) are well known in the art and can be constructed of any number of materials including plastic or wood , or combination thereof . a first clip 30 formed from a rigid material such as polyurethane , metal , or the like rigid material and can be permanently secured to the top surface 14 proximate to the tail end section 20 . the first clip includes a vertical upright 32 sized to extend a distance d1 above the lip of a shoe sole terminating with a horizontal extension 34 projecting toward the front end section 18 a width w 1 which permits extension over the edge or “ lip ” of a shoe sole . for instance , common deck shoes such as those manufactured under the name docksiders have a sole with leather uppers sewn to the sole leaving an exposed lip approximately ⅛ inch thick by ¼ inch width . the distance d1 of vertical upright 32 and width of horizontal extension w1 is sized to accommodate the shoe sole arrangement . in addition , it is well known that shoe soles are flexible which is necessary to walk . this flexibility provides a relief should a rider fall as will be explained later in this specification . the clip 30 includes an upper angled surface 36 that allows for a comfortable placement between the shoe sole and the shoe upper . the clip 30 can be permanently secured to the platform 12 by a fastener such as a bolt , screw , glue or the like . alternatively , a permanent attachment may consist of forming the clip as an integral process in the formation of the platform . the clip allows a rider to hook their shoe beneath the clip so as to temporarily secure their shoe , and thus their foot , to the platform . the clip 30 allows the rider to freestyle , such as jump , without holding on to the platform . should the rider fall , the inherent flexibility of shoe sole will instantly allow release of the rider &# 39 ; s foot . a second clip 40 is also formed from a rigid material such as polyurethane , metal or the like rigid material and can be permanently secured to the top surface 14 proximate to the front end section 18 . the second clip includes a vertical upright 42 sized to extend a distance d2 above the lip of a shoe sole terminating with a horizontal extension 44 projecting toward the rear end section 20 a width w2 which permits extension over the edge or “ lip ” of a shoe sole . the distance d2 of vertical upright 42 and width of horizontal extension w2 is sized to accommodate the shoe sole arrangement which may or may not be the same style shoe worn on the other foot of the rider . the clip 40 includes an upper angled surface 46 that allows for a comfortable placement between the shoe sole and the shoe upper . the clip 40 can be permanently secured to the platform 12 by a fastener such as a bolt , screw , glue or the like . alternatively , a permanent attachment may consist of forming the clip as an integral process in the formation of the platform . as with the first clip 30 the second clip 40 allows a rider to hook their shoe beneath the clip so as to temporarily secure their shoe , and thus their foot , to the platform . the clip 40 also allows the rider to freestyle , such as jump , without holding on to the platform . should the rider fall , the inherent flexibility of the shoe sole will instantly allow release of the rider &# 39 ; s foot . the first and second clip are preferably located along a longitudinal axis which is defined as a center axis running along the middle of the platform . now referring to fig3 set forth is the partial view of a skateboard consisting of a platform 50 having wheels 52 located along bottom surface 54 of the platform . in this embodiment , clip 56 is depicted in a raised position having a bottom vertical extension 58 , a vertical upright 60 and an upper horizontal extension 62 . as with the previous embodiments , the vertical upright 60 provides a spacial distance d3 between the platform and the upper vertical extension 62 . similarly the upper vertical extension 62 projects over the platform a width w3 sufficient to engage a shoe sole . in operation a shoe fits beneath the upper horizontal extension 62 and against vertical upright 60 whereas in the previous embodiment the shoe of the rider is secured to the platform . as the individual pushes forward or upward the lower horizontal extension 58 is locked against the bottom surface 54 so as to prevent movement of the clip . when the clip is not in use , the upper horizontal extension is pushed into platform cavity 66 wherein it becomes flushed with the upper surface 68 of the platform and lower horizontal extension 58 is dislodged from the lower surface 54 . as shown in fig4 the clip is in a stored position wherein the upper portion of horizontal extension 62 is shown flush with the surface 68 of the platform 50 allowing an individual to stand directly over the clip 60 allowing use of the skateboard in its normal and everyday fashion . not shown are various alternative embodiments for hooking of the clip in a removable fashion , such as the use of a hinge so as the clip may be raised or lowered for use . in such an embodiment the clip would consist of an upright vertical section and a horizontal extension as shown in fig1 - 4 and when placed in a stored position the vertical extension is laid horizontal while the horizontal extension is placed into a vertical position wherein the clip is simply laid onto the platform with the upper portion extending through the platform for concealment . referring to fig5 shown is a conventional shoe 70 , such as the previously mentioned docksiders , having an upper sole 72 and a lower sole 74 . as noted , the lower sole 74 engages the clip 40 securing the shoes 72 to the platform surface 14 . pressure against the clip only serves to further secure the shoe in position with the chamber following the contour of the upper sole . [ 0029 ] fig6 shows another embodiment wherein shoe 80 is modified having an extended sole 82 for use in engaging a modified clip 84 . in this embodiment the modified clip 84 has an upper extension 86 which is enlarged so as to engage the shoe 80 for use in professional freestyling . as with the previous embodiments a chamfered section 88 allows for a comfortable fit to the upper sole of the rider . although this embodiment is depicted as a professional version , the clip variation serves to demonstrate that the clip can be made of any size and shape to accommodate a particular shoe sole &# 39 ; s width and height . further , the platform can be made of any shape or material including raised end sections designed for trick boarding . it is to be understood that while we have illustrated and described certain forms of my invention , it is not to be limited to the specific forms or arrangement of parts herein described and shown . it will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification .
disclosed is a skating device having clips that allows a rider to position the sole of a shoe beneath to the lip so as to secure a rider &# 39 ; s shoe to the platform . the clip may be permanently or releasably secured and sized to fit conventional shoes . a professional version includes a specialty shoe that provides additional securement . releasably secured clips may be concealed to allow the skateboard to be used in a conventional manner .
