Brodowski, Stratford, Conn, assignor of onehalf to John A. Di Lorenzo, Stratford, Conn. Filed Apr. 12, 1960, Ser. No. 21,814 11 Claims. (Cl. 24-117) This invention relates to releasible lace fastener devices, and more particularly to devices of this type which are intended to be worn on the shoe and which eliminate the necessity for tying the shoe laces.
While the invention is illustrated herein as applied to shoes and shoe laces, it should be understood that the invention is not limited to this specific use and application but instead has utility in connection with laces of any type, as used for various purposes.
An object of the invention is to provide a novel and improved releasible lace fastener device which is very simple in its construction, involving components of the simplest possible type and formation.
Another object of the invention is to provide an improved lace fastening device of simple construction, wherein an absolute minimum number of parts or components is involved, thereby reducing assembly costs.
A further object of the invention is to provide a novel lace fastening device in accordance with the foregoing, wherein the assembly operations involved in connection with the components are easily carried out, without the necessity for special or costly equipment.
Still another object of the invention is to provide an improved shoe lace fastening device as above set forth, which eliminates the danger of tripping over the laces.
Yet another object of the invention is to provide a simplified lace fastening device wherein the components are so few and simple that the cost of the tooling required to produce such components represents a low figure.
A feature of the invention resides in the provision of a simplified and economical-to-manufacture lace fastening device which is extremely easy to operate, both for the purpose of clamping or securing the laces and also for the purpose of releasing the same, all while [the device remains on the laces.
Another feature of the invention resides in the provision of a simple shoe-lace fastener device wherein the required operation or manipulation of the same may be easily understood and carried out, even by relatively small children.
A still further object of the invention is to provide an improved releasible lace fastener, which is reliable in its operation at all times and which will not readily get out of order.
An additional object of the invention is to provide a shoe-lace fastener as above set forth, which is attractive in its appearance, relatively small and compact, and which readily lends itself to ornamentation and the use of emblems and the like.
Other features and advantages will hereinafter appear.

The present improved shoe-lace fastening device shown herein comprises essentially a relatively low or squat,
cup-shaped body 10 having a cylindrical side wall 11 and a circular or disc-shaped bottom wall 12. The body 10 has lace inlet and outlet opening means, and it is preferred to provide as the outlet opening means a single elongate lace outlet opening 14 and as the inlet opening means a pair of spaced-apart, lace inlet openings 15, both said means being shown in FIGS. 2, 3 and 4. The inlet and outlet opening means 15 and 14 are disposed at peripheral portions of the body 10, the means 14 being in the peripheral wall 11 whereas the means 15 are located just within said peripheral wall. The term at as used herein is intended to signify a condition of close proximity, as well as a condition where the means in question is directly in or on the peripheral Wall.
The body 10 may be readily molded of plastic substance such as polyethylene, nylon (synthetic fiber forming polymeric amide) or other suitable formulations, and in the molding of the body the lace inlet openings 15 may be advantageously incorporated in the bottom wall 12 by the use of suitable core pins. Preferably the openings 15 have rounded edges to avoid any sharp cutting formations which might abrade the shoe laces entering and which are brough through the body. Also, the outlet opening 14, which is preferably disposed both in the cylindrical side wall 11 and the bottom wall 12, may be formed at the time that the body is molded, by the use of a suitable core formation. The opening 14 also preferably has rounded edges to prevent abrasion of the shoe laces.
It will be noted from an inspection of FIG. 1 that the separate spaced-apart lace inlet openings 15 in the bottom 12 adapt the body member 10 especially well to positioning on the shoe upper at the highest lace holes in the upper, and enable the body to rest in a flat position on the shoe.
In contradistinction to such spaced-apart openings 15 for entry of the shoe laces, the laces are preferably brought out from the body 10 through the single elongate opening 14 whereby they are closely juxtaposed at the point of emergence, and are centralized on the shoe upper.
As seen in FIG. 1, ornamental enlargements such as small balls or spheres 17 may be provided on the free ends of the laces 18, to prevent the latter from being inadventently pulled through and removed from the body 10 of the lace fastener.
In accordance with the present invention, in conjunction with the simple and easily molded plastic body 10 there is provided a simple, easily actuated spring clip device adapted to be placed within the body and held thereby in operative position, said spring clip device providing a constrictable channel means through which the shoe laces 18 are passed, and by which the laces are either clamped or else released for free movement.
Referring to FIGS. 2 and 3, the spring clip shown therein comprises a peice of thin sheet metal of spring temper. The clip has a generally circular or disc-like base portion 20 provided with an upstanding hooked finger 21, the latter being lanced from the base in a manner well understood in the mechanical arts. The spring clip further has a cooperable clamping portion 23 overlying the center of the base portion 29, said clamping portion having a slot 24 through which the upper part of the hooked finger 21 extends, as seen in FIG. 3. The hooked finger 21 and the slotted portion 23 of the spring clip thus provide an opening or channel through which the two ends of the laces 18 may be passed. Depending on the position of the clamping portion 23, the said channelmay be constricted (as when said portion is free) or else enlarged (as when the portion is pressed downward) thereby to either clamp the laces passing through or else release the same for firee movement. T o facilitate actuation of the overlying clamping portion 23 of the spring clip, there is provided on said portion a turned back end or extremity 25, which is arranged to overlie the hooked finger 21 and adapted to respond to finger pressure, for the purpose of depressing the clamping portion 23. Normally, such portion tends to have a raised position wherein the shoe laces passing under the hooked finger 21 will be securely clamped and held against movement. However, when the finger piece 25- is depressed, the shoe laces will be released, as will now be readily understood.
In accordance with the invention, a thin walled flexible and resilient cover piece 27 is provided, having a flanged periphery 28 adapted to snap over a cooperable bead 29 on the body member 10. The formation and disposition of the cover piece 27 are clearly illustrated in FIG. 3. With such cover piece in place, finger pressure on the center portion of the cover piece will result in releasing movement of the clamping arm 23 of the spring clip, whereupon the shoe laces are free for movement. However, when pressure is removed from the cover piece 27, the spring arm 23 will resume a normal raised position, whereby the shoe laces passing under the hooked finger 21 will be clamped and held against free movement.
The operation and actuation of the present improved shoe lace fastening device may now be readily understood, considering FIG. 1. In this figure, the shoe is shown as being properly laced, with the fastener operative to secure the laces against loosening. The end portions of the laces 18 are extending forwardly and downward of the fastening device as shown. When it is desired to release the laces the fastening device is raised slightly and grasped between the fingers of the hand, and squeezing pressure is applied in a natural manner to depress the flexible top piece 27 at its center. This will cause a release of the spring clip, whereupon the fastening device may now be readily slid along the laces 18 until the ball enlargements 17 are encountered. Sufficient slack is thus provided in the shoe lace to permit the shoe to be loosened and removed from the foot.
As seen in FIG. 1, the flexible cover piece 28 may be provided with various types of emblems or other ornamentation. The figure of a star is indicated in H6. 1, and fraternal emblems, society emblems and various insignia may be utilized, as will be readily understood.
An important feature of the invention resides in the provision of the two spaced-apart bottom openings 15 located along the peripheral portion of the body member 10, whereby the fastener device may lie flat and also be swung upward from the ilat position shown in FIG. 1 for the purpose of grasping it between the two fingers of one hand. Then, upon exerting a squeezing pressure the fastener may be released and readily slid along the laces to the extremities thereof.
FIGS. 5, 6 and 7 illustrate a modified form of spring clip means which may be utilized in place of the one piece spring clip shown in FIGS. 2 and 3. As seen in FIGS. -7, the spring clip comprises a generally circular or disk-like base 32 adapted to snugly fit within the body member in a manner similar to that shown for the base 20. Rigidly afiixed to the base 32 is an upstanding hollow and tubular clamping member 34 in which there is telescopically received an inner clamping member 36, the latter being held in raised position by a helical compression spring 37 confined within the outer member 34. A spun-in flange 38 serves to retain the inner member in place.
The inner and outer members have slots 39 and 40, adapted to be brought into registration when the inner member is depressed, as by the application of finger pressure to a top-most protruding portion 42 of such member. The shoes laces are passed through the registered openings 39 and 40, and normally the action of the spring 37 is such as to cause the laces to be securely clamped and held against free movement. However, when the inner telescoping member is depressed to correctly register the openlugs 39, and 4c, the shoe laces will be free for movement.
Another embodiment of the invention is idustrated in FIGS. 8 and 9. This embodiment comprises a generally low, squat cup-shaped body having, carried by its bottom wall 51, a plurality of tunnel-like structures 52, S3, 54 and 55. The tunnel-like structures 52, 5 3 are shown as being spaced apart and generally parallel, and provide inlet openings for the shoe laces 18. The tunnel-like structures 54 and 55 are shown as convergent, said structures terminating at the periphery of the body 5%? in the single outlet opening 57, whereas at the inside of the body the structures 54, 55 present lace passages which are separated or spaced approximately the same amount as the lace passages of the structures 52, 53.
In conjunction with the body 50 there is provided a spring clip formed of a thin metal strip having the shape of a flattened loop, with a bottom portion 59, end portions 60, upper clamping portions 61 and 62, and upwardly-offset extremities 63 and 6-4. The upper clamping portions 61, 62 are adapted to underlie the shoe laces 18, and such portions are normally spring-urged upward, thereby to clamp the shoe laces at the points where such laces leave and enter the tunnel-like structures 52, 53, 54 and 55. The oifset extremities 63, 64 constitute fingerpieces, by which the spring clip may be actuated to release the shoe laces 18. Such offset extremities will extend below and engage the undersurface of the central portion of the flexible top piece 27, for example, such piece being adapted for use with the body member 50, as may be readily understood. When no pressure is applied to the top piece, the spring clip 58 is in expanded condition, whereby the laces 18 are gripped and pinched against the tunnel structures 52, 55 and 53, 54 thereby to secure the laces against movement. Finger pressure on the top piece will compress the spring clip 58, thereby releasing the shoe laces for free movement. Thus it is seen that the operation of the lace fastener device shown in FIGS. 8 and 9, insofar as the user is concerned, is the same as that of the embodiment of FIGS. 2, 3 and 4, and this is also true of the fastener employing the spring clip of FIGS. 5, 6 and 7.
It will now be understood from the foregoing that I have provided a novel and improved, greatly simplified lace fastening device having a number of distinct features and advantages. The device is small and compact, and extremely simple in construction. It has relatively few components, and the said components may be economically fabricated and assembled.
Moreover, the device is simple to operate, and the operation is easily understood, even by children of tender years. Also, the hazard of tripping over untied laces is completely eliminated. The cost of producing the fastener is low, to such extent that it may be universally used in conjunction with shoes worn by all kinds of people, both children and adults. The fastener lends itself readily to ornamentation and to the use of emblems, whereby it may serve as a distinguishing mark or badge.
The present device may not only be readily fabricated in part of plastic but metal, leather and other suitable materials may also be used. The use of the cap 27 masks the clip and the functioning thereof, so that the operation and working parts are largely concealed, and are protected.
Variations and modifications may be used within the scope of the claims, and portions of the improvements may be used without others.
