U.S. Cl. 24-117 12 Claims Int. Cl. A43c 1]/00 ABSTRACT OF THE DISCLOSURE A shoe lace coiler for piggy-back mounting upon a shoe is disclosed for coiling and releasably holding the lace tightly drawn upon the shoe. The coiler comprises a coiling motor in the form of a spindle having a length several times its diameter and having a slot for receiving the lace ends in gripping relation, a housing journaling the rotor therein to deiine an annular lace storage chamber, 4the housing having a window for lace travel, and a `winding control engageable with the rotor and the housing for turning the rotor in a lace take-up direction, the control including a ratchet ywheel rotatable with the rotor and selectively engageable with ratchet teeth on the housing for holding the rotor against reverse rotation.

This invention relates to a lacing method and to a lace coiler applicable to the loose ends of shoe laces for coiling and releasably holding the lace ends tightly drawn upon the shoe. When the lace ends are fully wound, the coiler is disposed in adjacent piggy-back relation upon the shoe.

The shoe lace coiler of this invention is provided for eliminating need for tying and untying the usual bow knot employed in shoe laces. The coiler has particular advantage as applied to childrens shoes where the knot tying and untying operation is an ever present problem.

The shoe lace coiler disclosed herein is comprised of an internal `coiling rotor arranged to receive and grip the extremities of the loose lace ends, the rotor being journaled in a surrounding housing which has a medial access window for travel of the lace ends `during take-up and pay-out rotation of the rotor. Winding control means are provided for turning the rotor in a lace take-up direction until the entire unit rests in snug piggy-back relation upon the shoe. The winding control means are effective to hold the rotor against unwinding to maintain this piggy-back position and thereby prevent loosening of the lace binding action on the shoe. Loosening of the laces for removal of the shoe is accomplished by shifting the coiler away from the shoe to impart lace pay-out rotation to the rotor. The lace ends are conveniently retained engaged with the coiler .for subsequent tightening of the shoe laces.

In the particular embodiments illustrated herein, the control means includes cooperating ratchet teeth relatively rotatably reacting between the rotor and the housing structure and normally interengaging to prevent lace payout rotation of the rotor. A manually controllable actuating `means is provided to disengage the ratchet teeth.

In some forms, a manual winding knob is provided for turning the rotor and, in another form, a vwinding spring automatically acts to .turn the rotor in the lace take-up direction.

The rotor is removably insertable in the housing structure and as disclosed herein has a spindle open at one end so that the lace extremities may be knotted and inserted edgewise into the spindle, with the rotor thereafter being inserted into the housing so that the lace enters edgewise into the housing access window. The rotor has spaced regions journaled in the housing and the housing is of two-piece construction to enable assembly and disassembly of the unit.

Other features and advantages of the invention will be apparent from the following description and claims, and are illustrated in the accompanying drawings which show an illustrative embodiment of the present invention.

In the accompanying drawings forming a part of the specification, and in which like numerals are employed lto designate like parts throughout the same,

FIG. 1 is a perspective view illustrating a shoe lace coiler in piggy-'back position upon a shoe for holding coiled lace ends tightly drawn upon the shoe;

FIG. 2 is an exploded sectional view illustrating the principal parts of the coiler assembly illustrated in FIG.

FIG. 3 is a lengthwise section through the coiler assembly; and

FIGS. 4, 5 and 6 are lengthwise sections each illustrating a diterent embodiment of a coiler in accordance with the present invention.

Referring now to the drawings, a shoe is designated generally at S in FIG. l and, as illustrated, has a shoe lace L threaded therein in the usual way and engaged and stored in coiled relation within a coiler device 10 constructed in accordance with this invention. The coiler device 10 functions to hold the lace L tightly drawn upon the shoe with the coiler riding in piggy-back relationship upon the shoe. One embodiment of the coiler device is illustrated in FIGS. 2 and 3 and various dierent embodiments are illustrated in each of FIGS. 4, 5 and 6.

In the embodiment of FIGS. Zand 3, the coiler includes a rotor 11 arranged to receive and grip the lace ends L adjacent extremities thereof and surrounding housing structure 12 journaling the rotor 11 therein at spaced regions and defining a lace storage chamber C. The housing 12 is a two-piece assembly consisting of a sleeve like main body or cylinder 13 and a cup-shaped end body or cap 14 threadedly engaged thereon. The housing structure 12 has a medial access window W provided by an axially elongated slot located in the cylinder 13 4for travel of the lace during take-up and pay-out rotation of the rotor. Winding control means as designated generally at 15 is provided for turning the rotor in a lace take-up direction and for holding the rotor against reverse rotation.

The winding control mechanism 15 includes a ratchet wheel 16 having ratchet teeth 16T axially shiftably mounted in rotatable relation on one end of the housing structure to be selectively engageable with ratchet teeth 14T provided on the cap 14. In this form, the ratchet wheel 16 is in the form of a hand knob that has a drive pin 17 embedded therein and projecting therethrough and therebeyond to be releasably keyed into the rotor L11 for turning the rotor by means of the knob. The drive pin 17 projects through the end of the cap 14 and mounts a washer-like spring seat 18 to hold the ratchet wheel 16 in captive relation on the cap 14. A spring 19 reacts between the wheel 16 and cap 14 normally to bias the same so that the ratchet teeth engage and the drive pin 17 keys with the rotor 11.

The rotor 11, as illustrated herein, has an enlarged head 20 serving as a bearing hub journaled in the cylinder 13, with the rotor having a reduced spindle section 21 provided along slot 21S that opens axially through the spindle end which is to be journaled in an integral internal boss 13B provided on a cross wall 13W of the housing structure. Thus, both ends of the rotor are supported by the housing structure for free rotation. The open ended spindle slot enables the laces to be applied by first aligning and knotting the extremities of the lace ends and thereafter inserting the lace edgewise into the spindle slot to be retained by engagement of the knotted lace ends. The rotor is assembled into the cylinder 13 following engagement of the lace ends therein and, for this purpose, the cylinder 13 has a medial access window extending lengthwise thereof and opening through the open end thereof for receiving the gripped laces edgewise during insertion of the rotor.

In the embodiment illustrated in FIGS. 2 and 3, the end cap 14, which carries the ratchet wheel 16, is threaded onto the open end of the cylinder 13 to complete the housing structure to complete the unit and bring the end of the pin 17 into keying engagement with a socket 20S in the rotor head 20.

As indicated previously, the lace ends are aligned, knotted and gripped by the spindle 21 as a preliminary to final assembly. After assembly, the knob-like ratchet wheel 16 is turned in a lace take up direction to wind the lace upon the rotor (see FIG. 3) until the lace is fully coiled and the coiler is snugly seated in piggy-back relation upon the top of the shoe S (see FIG. 1). At each stage of turning the spring 19 maintains the ratchet teeth biased towards engagement to prevent rotation in a lace pay out direction. In addition, the ratchet teeth hold the lace in fully wound condition to prevent accidental loosening of the lace.

To loosen the lace for removing the shoe, the ratchet wheel 16 is shifted axially on the end cap y14 to free the ratchet teeth and retract the drive pin 17 until the rotor 11 is disengaged and ready for free wheeling rotation within the housing. The coiler unit is then moved away from the shoe to rotate the rotor and pay out the coiled lace. In normal use, the lace ends remain gripped on the rotor spindle as there is suicient free lace available to facilitate loosening and removal of the shoe.

In the embodiment illustrated in FIG. 4, the housing structure is somewhat modified but the essential functioning of the coiler unit is the same. Thus, the housing structure consists of a sleeve like main body 23 provided with an access window W and threaded at its open end to cooperate with an end cap 24. The end cap 24 has an internal boss 24B for rotatably supporting the spindle end of the rotor 11 while the bearing hub of the rotor rides in the closed end of the main body adjacent a integral cross wall 23W. The knob-like ratchet wheel 16 is mounted in captive axially shiftable relation on the cross wall and has ratchet teeth 16T engageable with ratchet teeth 23T provided externally on the cross Wall 23W.

The rotor 11 is bodily removable from the housing structure by removal of the end cap 24, however, in this form the lace ends may be knotted and secured in gripped relation on the spindle merely by removing the end cap 24. The rotor winding and unwinding action is controlled in the same fashion by the ratchet wheel 16.

A modified form of coiler as illustrated in FIG. 5 incorporates a number of additional important features. In this form, the housing structure consists of a main body cylinder 33 having a medial access window W and a threaded end cap 34 for closing the open end of the main body. A one-piece rotor 31 is removably journaled in the housing structure, the rotor 31 having an enlarged head 40 intermediately of a winding spindle 41 and a drive stem 42. The enlarged head 40 is provided with ratchet teeth 40T engageable with ratchet teeth 34T provided internally on the end cap to complete an internal ratchet system.

The rotor drive stem 42 projects through and beyond the end cap 34 to receive a winding knob 36 held in splined engagement thereon by a cap nut 36N. An integral cross wall 33W has an internal boss 33B for rotatably supporting the spindle end of the rotor while also accommodating axial shifting of the rotor to enable engagement and disengagement of the ratchet system.

A coil spring 39 reacts between end cap 34 and the winding knob 36 normally to bias the rotor to the position illustrated in FIG. 5 wherein the ratchet system is engaged. In this position, the winding knob 36 can be rotated to turn the rotor in a lace take up direction, with the ratchet system serving to prevent reverse rotation and to hold the fully coiled lace tightly drawn upon the shoe. To unwind the coiled lace, the thumb and linger are pinchingly engaged on the cross Wall 33W and the cap nut 36N to shift the rotor free of the ratchet system while the entire coiler is shifted away from the shoe to cause the rotor to free wheel in a lace payout direction. Manipulation of the coiler for lace payout is thus facilitated in this form, in that a one handed pinching action serves both to disengage the internal ratchet and to shift the coiler to produce unwinding of the rotor.

Another aspect of the coiler structures of this invention resides in the fact that the external appearance of the unit may be easily varied to resemble any one of a number of toys. This is accomplished simply by appropriate decorating and contouring of the housing structure. This feature makes the coiler particularly appealing to children. For example, the coiler illustrated in FIG. 6 is arranged to simulate a football.

A unique winding control arrangement is utilized in the coiler of FIG. 6. A coil spring drive 56 is utilized in place of a manual winding knob. The housing structure is comprised of mating halves 53 and 54 threadedly engaged and jointly mounting a one piece rotor having an enlarged head 50 intermediately of a winding spindle 51 and a control stem 52. The enlarged head 5t) is provided With ratchet teeth 50T engageable with ratchet teeth 53T provided internally on the housing structure.

The housing structure incluldes integral end walls 53W and 54W, with the rotor being mounted in these end walls in axially shiftable relation. A spring 59 is recessed in an internal socket provided in the cross wall 54W and normally urges the ratchet wheel into engagement with the ratchet teeth 53T. A cap nut 52N xed externally on the control stem is manually engageably to shift the rotor against the spring 5% for disengaging the rotor from the ratchet system.

The drive spring 56 is in the form of a coiled band having one end engaged to the spindle and the other end engaged to the housing 53, with the spring 56 normally acting to drive the rotor in a lace take up direction. A washer 57 is mounted on the spindle alongside of the spring 56 to prevent fouling of the lace in the turns of the spring. The spring 56 can rotate the rotor while the ratchet system is engaged, with reverse or lace pay out rotation normally being prevented both by the spring action and by the ratchet action.

The embodiment of FIG. 6 is also operable by a simple one hand pinching action. The knotted lace ends are engaged in the spindle when the drive spring 56 is maintained tightly wound. The spring 56 then turns the rotor in a lace take-up direction to coil the lace about the spindle and draw the coiler into snug piggy-back relation upon the shoe. The spring tension then serves to maintain the lace tightly drawn upon the shoe and the ratchet system also aids in preventing accidental unwinding.

To loosen the lace the thumb and finger pinch against the cap nut 52N and the housing 54 to the rotor axially and disengage the ratchet teeth. While this pinching action is maintained the coiler is shifted bodily away from the shoe to pay out lace and rewind the drive spring.

Thus, while preferred constructional features of the invention are embodied in the structure illustrated herein, it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit and scope of the appended claims.
