referring now to the drawings , there is illustrated , in fig1 a front perspective view of the shoe 10 utilized in this invention , with fastening straps 12 , 14 , and 16 ( not fastened ) to reveal lacing eyelets 18 and lacing hooks 20 . the shoe 10 rides relatively high on the wearer &# 39 ; s ankles , as shown in fig2 and 3 , and can be snugly secured around the wearer &# 39 ; s ankles by use of the straps 12 , 14 and 16 and / or shoe laces ( not shown ) which can be tightly laced through the eyelets 18 and lacing hooks 20 . the use of shoe laces provides for a snugger fit than by the straps 12 , 14 and 16 straps , but the use of straps 12 , 14 and 16 allows the shoes 10 to be put on and removed more quickly as timing , for this particular &# 34 ; move ,&# 34 ; may be extremely critical and of short duration . in order to conceal the nature of the shoes 10 , the front of strap 12 can be made to appear as the tongue and strap of a penny loafer . spats ( not shown ) or pant legs can be used to cover the upper part 22 of the shoes 10 , as best shown in fig6 and the lower part 24 of the shoe 10 will thus be made to appear as a normal walking or dance shoe . also , as shown in fig4 and 5 , an upper sock section 26 can be used to conceal the upper part 22 of the shoe 10 , the sock section 26 fitting around a peripheral edge 28 of the shoe 10 . referring to fig7 - 10 , the heels 30 of the shoes 10 have a recess 32 formed therein adapted to detachably receive a hitch or post 34 , thereby locking the heels 30 of the shoes 10 in place relative to the stage surface s through which the hitch 34 protrudes . a v - shaped guide 40 is located below recess 32 , with the mouth of the v located at the leading edge 42 of the heel 30 . the guide 40 forms the entrance to the recess 32 . the front of the v - shaped guide 40 lies flush with the leading edge 42 of the heel 30 . edges 44 , forming the v - shaped guide 40 terminate rearwardly of leading edge 42 at a terminal end point 46 . the v - shaped slot 40 is formed in the lower region 36 of the heel , preferably by two layers of materials , an outer or exposed layer 60 , preferably made of leather , and an inner overlying layer , preferably consisting of a metal plate 52 . the upper region 38 of the heel , above the metal plate layer 52 has the hitch - post receiving recess 32 formed therein . the metal plate 52 is affixed to the heel portion of the shoe , as described hereafter . referring to fig9 - 12 the shoe hitch 34 preferably comprises a pair of steel bolts , each bolt 51 having an enlarged preferably rounded head 48 relative to its shank 50 . enlarged bolt head 48 has a diameter less than the width of the recess 32 . the bolt shank 50 is of somewhat less diameter than the mouth of the v - shaped guide 40 . the head 48 is wider than the terminal end point 46 of the v - shaped guide 40 . the recess 32 is formed so that it is wider than the head 48 of the hitch 34 . as shown in fig9 and 10 , when the heel 30 of the shoe is placed over the bolt head 48 so that the mouth of the v - shaped slot 40 overlies the head 48 , the heel 30 may then be lowered and slid forwardly until the shank 50 of the hitch 34 contacts both edges 44 of the v - shaped guide 40 . the bolt head 48 will lie in recess 32 above said v - shaped slot guide 40 , and the shoe will be stably positioned relative to the stage floors . three countersunk bolts 56 and threaded inserts 58 can be used to assure reliable affixation of the metal plate 52 of the heel 30 to the rest of the shoe 10 . the exposed outer layer 60 of the heel is affixed to the perimeter 61 of the heel ( outlying the metal plate 52 ) by suitable conventional adhesive and / or tacking means ( not shown ). referring to fig9 and 12 , the bolts 51 of the hitch 34 are made to be movably protrudable through holes or openings 62 formed through the stage surface s . the holes 62 are oversized so as to allow the bolt heads 48 to freely pass therethrough . the bolts 51 are permanently affixed to a metal plate 64 , and the length of the bolt shank 50 of the bolts is such that when the metal plate 64 carrying the bolts is stably placed against the underside of the stage surface s , the head 48 will be spaced sufficiently high off the stage surface s so that the bottom edge 66 of the head 48 will clear the top edge 68 of the metal plate 52 , leaving a slight gap g . this slight gap g will allow the entertainer to slide his or her shoes 10 forward to engage the head 48 of the hitch 34 with the v - shaped slot 40 . it has been found that a gap g of approximately one - eighth of an inch is ideal for lighter dancers , while slightly deeper gaps are required for heavier dancers . also , referring again to fig9 the metal plate 60 is formed so that its v - shaped slot edges and the v - shaped edges 70 of the heel covering material 60 form flush v - shaped edges 44 . the v - shaped guide 40 , so formed , is preferred , as it minimizes the chances of the hitch 34 inadvertently becoming jammed in the v - shaped guide , and thereby preventing the shoe 10 from being disengaged from the hitch 34 after the &# 34 ; anti - gravity &# 34 ; move is completed . turning again to fig1 and 12 , a simple mechanical means can be used to stabilize the metal plate 64 with its bolts 51 relative to the stage surface s . for this purpose , slide brackets 72 are affixed to the underside of the stage surface s . after the metal plate 64 is positioned and bolts 51 aligned with openings 62 , one or more metal support bars 74 can be slid into the sliding brackets 72 , and under the metal plate 64 , to hold the plate 64 tightly against the underside of the stage surface s . also , as is shown in fig9 and 12 , if it is desired to plug the holes 62 in the stage surface s when the hitches 34 are withdrawn , plug protrusions 76 can be provided on another side of the metal plate 64 . when the metal plate 64 is oriented with the plug protrusions 76 directed upwardly , the metal plate 64 can be immobilized relative to the stage surface . the plug protrusions 76 will be just long enough so that they lie essentially flush with or the stage surface s . a chain 78 or other means may be used to retain the metal plate 64 to the underside of the stage surface s , if desired . referring to fig1 , multiple pairs of hitches 34 can be provided on a single metal plate 64 , if desired . in lieu of the mechanical means , alternate mechanisms can be provided to raise and lower the hitches by pneumatic , electromagnetic , hydraulic , other mechanical means , or by any other known means . as presently contemplated , the hitch 34 will be raised and lowered by stage personnel stationed under the stage surface s . the inventors also contemplate that the hitch 34 could also be raised by the entertainer himself or herself by remote control means , such as by radio control , when automated means is used to raise and lower the hitches 34 . when the hitch 34 is locked in its raised position , the performer can engage his or her heels 30 with the hitch 34 , and he or she can then safely lean forward as far as he or she desires and is capable of , so that his or her center of gravity cg lies in front of the shoes 10 , as shown in fig6 . after returning to a normal standing position , the dancer can slide his or her shoes 10 rearwardly , thus readily disengaging from the hitches 34 . thereafter , the hitches 34 can be pulled out of the holes 62 in the stage and plugged , if desired . referring to fig1 , it has been found that the pair of hitches 34 should ideally be spaced between the shoulder blades of a dancer , a width of approximately 14 - 20 &# 34 ; apart . such a spacing provides maximum stability during the leaning . the drawings and the foregoing description are not intended to represent the only form of the invention in regard to the details of this construction and manner of operation . in fact , it will be evident to one skilled in the art that modifications and variations may be made without departing from the spirit and scope of the invention . although specific terms have been employed , they are intended in a generic and descriptive sense only and not for the purpose of limitation , the scope of the invention being delineated in the following claims :
a system for allowing a shoe wearer to lean forwardly beyond his center of gravity by virtue of wearing a specially designed pair of shoes which will engage with a hitch member movably projectable through a stage surface . the shoes have a specially designed heel slot which can be detachably engaged with the hitch member by simply sliding the shoe wearer &# 39 ; s foot forward , thereby engaging with the hitch member .
