the invention is an arrangement of holes and grooves lace attachments that can be combined in over a hundred possible ways . a lace 24 goes through a hole attachment 22 and goes by a groove attachment 23 one or more times . when the lace crosses over a frontal shoe opening 21 for the purpose of closing the shoe , the lace goes from the hole attachment to the groove attachment or vice versa as the case may be . the two ends of the lace are found secured prior to wearing the shoes and can be either : ( b ) one end tied to the shoe upper and the other end attached to an annulus 49 or , in all embodiments , two devices are added to the lace circuit : 1 . one device is a slack reducing means which can be either : ( a ) a slack reducing attachment 54 placed further apart from the edge of the shoe frontal opening . ( b ) a protrusion with transversal horizontal grooves 42 on its surface . 2 . the second device is a hinged fastener of the type shown in fig3 and 3a with a tension lever 20 and a groove 25 or of the type shown in fig1 with a hole 56 to engage the lace . but many other types of tension lever are possible . a typical embodiment is illustrated in fig1 with the shoe open , and fig1 a with the shoe closed . on one side of shoe frontal opening 21 are protrusions with peripheral groove 23 , and tension lever 20 . on the opposite side of the shoe are the protrusions with holes 22 . the lace arrangement with the shoe open and closed is detailed in fig2 and 2a . in these 2 drawings , each end of the lace is secured to the shoe upper with a stopper 27 blocking the lace from entering a single hole attachment 29 . the lace arrangement in fig1 & amp ; la utilizes protrusions with two holes fig4 . this auxiliary improvement pre - disposes the formation of a loop 26 to be wrapped around opposite protrusion with groove 23 . for closing the shoe fig2 a , the lace is held by groove 25 of lever 20 , fig3 & amp ; 3a . once lever 20 is closed , the tighten lace banks against a ridge 32 and , if elected in the construction of the fastener , is maintained against ridge 32 by passing in a gap 34 under a bulge 33 . another embodiment is shown in fig1 and 10a where holes and grooves attachments now alternate in pairs . this time , a loop 28 crosses an opposite one as the lace leaves the hole to go to the groove . one end of the lace is attached by a connecting member 51 to an annulus 49 . the permanent slack in the lace can be adjusted where the lace is tied to member 51 . a tension lever 50 has grooves facing the shoe upon its closing . in this embodiment the tension lever does not need a ridge to hold the tension because of the annulus . in embodiment shown in fig1 and 11a , the hole attachment is a half ring 63 and the lace is tied by a knot 55 to establish a permanent slack . the overlapping loops are between two hole attachments on the same side of the shoe frontal opening . a lace holder 53 maintains the lace as it goes to the back of the shoe . endless loop arrangement 62 is shown in fig1 and 15a . a single hole protrusion 61 above the shoe upper has hole parallel with the edge of the shoe upper . in embodiment shown in fig1 and 17a , the lace is separated in two circuits with two fasteners . this arrangement for high cut shoes permits a different tension level around the ankle . in many embodiments the lace is engaged directly in one of the grooves of the tension lever . to prevent the lace under tension from pushing against the foot and unsnapping the fastener the lace banks against ridge 32 . ridge 32 extends along grooves 25 on both side of lever 20 . this ridge is a substitute for the rigidity of the metallic annulus . the user &# 39 ; s only motions for closing the shoe with the present invention are to grasp the lace as it leaves the hole attachment and position the lace in the grooves . to make this task easier , the hole attachment is designed to constrain the lace into making a loop by coming in and out of a pair of holes 30 above the shoe upper . the protrusion has a recess 38 making it easy to grasp the lace for positioning around the groove . a lace phantom path 40 inside two holes protrusion 22 is shown on fig4 a . exit of lace by a notch 39 can be used to hold the end of the lace . the typical shoe hook is improved in this invention to prevent anything from being caught accidentally and causing injury . in fig5 the lace is held by a shallow peripheral groove 41 with just enough width and depth for the lace . whenever a tension lever with a hole or a twin hole to hold the lace is used , there is a need for a device to regulate the slack in the lace . one of transversal surface groove 42 is used to regulate the slack and change tension in the lace circuit . fig7 is a front view of a rotating lace catcher . gap 34 under rotating bulge 33 extends at a end of hinge movable part 35 . when the lever with the lace engaged in the groove is rotated , the bulge rotates with it and the lace is caught in gap 34 when the fastener closes . with the catcher , - he lace is maintained below the hinge &# 39 ; s fulcrum and adds security against the lever snapping open under foot pressure . in fig8 a stationary bulge 43 extends at a end of the hinge &# 39 ; s stationary part 36 . here , the bulge does not rotate with the lever . when the lever rotates toward its close position , the elasticity in the lace causes it to pass over the bulge and take position in gap 34 . one concern with the tension lever is to have it un - snap under strenuous foot activities such as tennis . several types of locking means can be added to the fastener to prevent the tension lever from opening under tension . fig9 shows a plate 31 supporting lever &# 39 ; s hinge , extending to the length of the lever . on the plate is a number of nearly vertical studs 44 , one stud for each corresponding groove on the lever . at the base of each stud is an under - cut 45 facing the hinge that catches the lace once the lever is closed . in the center of each groove 25 is a curved recess 46 perpendicular to the plane of the lever . upon closure of the lever , stud 44 enters into recess 46 of the corresponding groove . the lace is caught by under - cut 45 of the stud . fig9 a shows a variation of the preceding locking means . an under - cut 47 in stud 44 faces the end of the lever . in the center of each groove is a cavity 48 on the vertical wall of the groove . when the lever is closed , stud 44 takes position inside cavity 48 . the lace is then caught by under - cut 47 . fig1 shows an alternate lever lock being a ring 59 attached to a support 60 on the shoe upper . the ring can be tilted to catch and hold down a raised end of lever 37 . in this version of the tension lever , a twin hole 56 is mounted on a lever 57 and the lace is circuited in the twin holes where it slides freely . the lace goes in the center of the hinge where it passes over rotating bulge 33 to be caught in gap 34 . stud 44 on plate 31 enters into an aperture 58 upon closing of lever 57 and under - cut 47 catches the lace and holds the lever closed . under tension , the lace banks against ridge 32 . lace tensioning with the lever is regulated by a slack reducing attachment 54 as in fig1 . annulus 49 transfers the line of pull by the lace on lever 50 , below the lever &# 39 ; s hinge fulcrum . it prevents lace tension to : connecting member 51 holds the floating annulus and the lace . the lace slides inside member 51 and the lace pressure is distributed on the entire lace . the slack necessary and sufficient to install the lace in the grooves should be less than 2 inches . beyond this , the slack is reduced by other means than the tension lever . changing the slack in the lace can be done with a protrusion having multiple grooves as shown in fig6 ; or slack reducing protrusion with groove 54 installed further away from the edge of shoe frontal opening as in fig1 . in many embodiments , the lace is secured to the shoe upper . one preferred way to immobilize the end of the lace is - o have the lace going in and out of small member 27 that itself cannot go through hole 29 as shown in fig2 . having the lace traversing the hole in member 27 , and after having made a sharp bend come back into the same hole , is sufficient from preventing the lace from slipping inside the hole . notch 39 of protrusion shown in fig4 can be used in the same manner to hold the end to the lace and so can a hole in connecting member 51 shown in fig1 . the common shoelace requirements of flexibility with gripping properties to hold the knots is out of order . the preferred lace for most of the proposed embodiments has a slippery surface to slide easily in the holes and around the grooves . the sliding improves distribution of tension on the entire lace . the lace can now be made : ( 1 ) more resistant , ( 2 ) more durable , ( 3 ) less pliable and subject to fraying ( 4 ) less soft and subject to becoming dirty than the common shoe lace ; by using more synthetic material in the lace composition . a lace less flaccid than ordinary shoe lace will maintain its general position and be easier to position around the grooves and disengaged from same . the usual requirements for the tongue are linked to the space between the edges of the frontal openings . in conventional shoes , this space serves several functions : ( c ) to cushion the foot against lace pressure , pressure which increases with the width of the frontal opening . without holes into the shoe upper , as it is possible with many embodiments of the invention , the tongue can be sewn to one side of the shoe frontal opening . this would resolve the problem of tongue migration under strong foot motions . at rest , the opening of the shoe is completely un - restricted as shown in fig1 and 2 . once the foot is in place the shoe frontal opening is closed fig1 a and 2a . on one side of the shoe frontal opening are holes 22 and on the other side of the opening are grooves 23 . fig2 a shows the ends of the lace secured in attachments 1a and 6a to set the slack in the lace . once the slack is set for the wearer there is no need to change it again . the lace goes in and out of protrusion with two holes in lace attachments 2a , 3a , 4a and 5a . each time , the lace makes loop 26 . once the foot is in place , the shoe is closed ; fig1 a and 2a . the lace is wrapped , possibly with one hand , around protrusions with groove 23 in attachments 2b , 3b , and 4b . loop 26 is wide enough for the finger to grab inside it and carry it around groove 23 . when pulling loop around 3b , the preceding loop is already in place around 2b . the need for slack in the lace remains nearly constant and is sufficient to go around each peripheral groove , one at a time . when the lace is engaged on all the grooves of the protrusions the last loop is engaged in one of the groove of the tension lever . the tension lever in fig3 stands in an open position . upon closing the lever in fig3 a the lace slides down against bulge 33 to take position in gap 34 . fig1 and 10a . in this embodiment , holes 29 and grooves 23 alternate in pairs . crossing loops 28 are disengaged from grooves 23 to open the shoe . each end of the lace is tied to annulus 49 by connecting member 51 . member 51 is also used to regulate the slack in the lace . in this version of the tension lever , the grooves face the shoe upon closure . starting from the middle of the lace between eyelets 1a and 1b , the even attachments are grooves and the odd attachments are holes . one half of the lace goes from 1a to 2b to 3a to 4b to 5a and to the annulus . the second half of the lace goes from 1b to 2a , 3b , 4a , to 5b and to the annulus . embodiment where grooves are on one side of the shoe opening . fig1 and 11a . in this embodiment grooves 23 are on one side of the shoe opening and holes 63 on the other side . this disposition allows for the use of the common shoe lace . in 1b , 1a , 2a , 2b , 3a , 4a , 5a , 6a , 7a are holes and in 3b , 4b , 5b , 6b are grooves . tension lever 57 with hole 56 and ridge 32 as shown in fig1 and 13 is at the heel . the lace goes around part of the ankle increasing the security of the attachment to the foot . the lace makes an overlapping loop 52 as it crosses its path going up and down the shoe frontal opening . permanent knot 55 between 1a and 1b is pre set to the proper slack for the desired tension . afterwards , the lace is placed around the grooves and one snap of the tension lever establishes the final tension . to remove the shoe , the tension lever is opened releasing slack in the lace . the lace is then disengaged from the grooves while held in its general position by the holes . an alternative to having the wearer knot the ends of the lace between 1a and 1b is the looped lace . slack in the looped lace can be manipulated with secondary groove attachment 54 or with attachments having multiple grooves as shown in fig6 . fig1 and 15a . this embodiment is possible with the two previous arrangements . the two ends of the lace are either tied together or secured to the shoe upper . the hole attachments shown here are protrusions above the shoe upper with one hole 61 . lace holders 53 holds the lace around the ankle . the lace makes endless loop 62 . the floating annulus channels the tension created by the lever on the entire lace . many variations of the preceding embodiments are possible . the specifications are the same : 1 . the two ends of the lace are secured as follows : ( b ) one end tied to the shoe upper and the other end tied to a member holding an annulus . ( e ) both ends tied at the factory or an endless loop . 2 . the lace is engaged alternatively into the hole attachment and on the groove attachment and when the lace crosses over the shoe frontal opening , the lace goes from the groove to the hole or vice versa as the case may be . 3 . the tension in the lace is established by a fastener . accordingly , the reader will see that the lace arrangement with fastener of this invention can be used effectively to replace the ordinary lace for all kinds of shoes . the inserting of the foot in the shoe and its removal have been made simple . the opening and closing of the shoe that are separate and distinct operations have also been made simple . comfort , adaptability , versatility , safety , reliability and durability are qualities apparently inherent with the invention . these qualities generally have an enormous market appeal . the appearance of the shoe is bound to be enhanced by these improvements . although the preceding description contains many specificities , these should not be construed as limiting the scope of the invention but are only intended to show the versatility of the invention and the many ways the described elements can be fabricated and combined in hundreds of ways to satisfy different requirements . for example , a shoe for soccer may require a continuous strip of material for the holes and grooves attachment , on each edge of the shoe frontal opening , with no space between each attachment . the tension lever in the back of the shoe may have to be encased in plastic rubber . the descriptions only disclose some of the possibilities of the invention but the scope of the invention is to be determined by the claims and their legal equivalents rather than by the examples given .
a shoe lace arrangement with fastener where a lace is engaged in a hole attachment and becomes engaged on a groove attachment as it crosses over a shoe frontal opening . the lace ends are tied permanently leaving enough slack to disengage the lace from the groove . once the lace is removed from the groove , a lace loop begins in one of the hole attachment and ends in one of the hole attachment on the same side of the shoe frontal opening ; thus allowing the un - restricted opening of the shoe . the slack is adjustable by lace placement in a grove . final tension in the shoe lace arrangement is obtained with a tension lever .
