Jan. 13, 1953 J.-RAVE MEANS FOR FASTENING SHOELACES Filed March 12. 1952 Jean Raye Patented Jan. 13, 1953 MEANS FOR FASTENING SHOELACES Jean Rave, Nice, France, assignor to Rapco S. A., Tangier, North Africa, a corporation of Tangier Application March 12, 1952, Serial No. 276,142 In France March 26, 1947 3 Claims.

This invention relates to an improved fastening means, and more particularly, to an improved fastening or fixation means comprising a twopiece buckle-like assembly for use in fastening a longitudinally extendir flexible member, such as a lace, thong or belt to a suitable base material or to the opposite end of such lace, thong or belt.

In general, shoe laces are tied first by making a knot and then by making a slip knot, in a bow knot arrangement. Not only does the bow knot arrangement offer difliculties in connection with the time and effort involved in accurately tying the same, but also the knot tends to become untied readily, thereby to cause additional trouble and difficulty.

Belts, thongs of leather or fabric, and the like are, likewise, difficult to tie and are inclined to become untied during normal wear.

The instant invention provides a unique twopiece buckle-like assembly, which may be slipped in and out of locking engagement easily and without the necessity of tying any knots in the lace, thong, belt or the like flexible material employed. The instant in that it includes two shoe lace or the like element to be connected and which consists of a loop or frame defining a'central aperture and designed for receiving the second part; and, a second part, which comprises a slide or frame member having two apertures separated by a cross piece, the lace passing through these apertures and astride or overlapping the cross piece, so that the slide may be slid along the lace and so that the lace may be suitably tightened by pulling the same over the cross piece while the slide and loop are in locking engagement.

It is therefore an important object of the instant invention to provide an improved fastening means for a lace, belt, thong or the like.

It is a further object of the instant invention to provide an improved fastening means of the type described for bringing together two ends of a suitable lace-like material merely by connecting two buckle-like pieces, without the necessity of tying knots or threading the lace-like material through the buckle-like pieces in order to obtain the locking engagement therebetween.

It is another object of the instant invention to provide a two-piece buckle-like fastening means of the type described that is adapted to afiord disengagement therebetween quickly and easily.

It is still a further object of the instant invention to provide a lace fastening means which will t automatically maintain a locking position but which may be readily adjusted at will merely by pulling on one end of the shoe lace cooperating therewith.

It is still another object of the instant inveninvention is characterized distinct parts: a first part, which is permanently attached to one end of a tion to provide a fastening means of the type described that is sturdy, durable, inexpensive, and uniquely uncomplicated in fabrication as well as operation.

Other objects, features and advantages of the present invention will become apparent to one skilled in the art from the following description of preferred embodiments thereof illustrated in the accompanying drawings, in which:

Figure 7 is still another sectional elevational view, similar in character to the views of Figures 4 and 6, showing still another fastening means embodying the invention, in this case, particularly adapted for use with a belt; and

Figure 8 is a top plan view of the preferred embodiment of the invention shown in Figure '7, showing the slide and loop of that embodiment in separated position.

In the embodiment of the invention illustrated in Figures 1-5, inclusive, the reference numerals It and l I indicate, respectively, a loop and a slide, which are the two buckle-like pieces of the instant fastening means.

The loop l0 consists of thin thread-like or strip-like material, shaped to form a generally elliptical rigid frame having a large central aperture, as at l2. The loop It also has a small generally hemi-annular integral formation l3 protruding from one end thereof which forms a slight extension to the aperture 12 and whereat a suitable flexible lace I4 may be attached.

As is shown best in Figures 3, 4 and 5, the lace l4 may be doubled over the loop H] at the hemiannular portion l3 and then passed through an eyelet I5. The shorter or loose end I4a of the lace I4 passing through the eyelet I5 may be knotted, as at I5, so as to prevent slipping of the lace I4 through the eyelet I5 and around the hemi-annular portion I3 in response to pull on the working end I4b of the lace I4. It will thus be seen that the arrangement just described affords hinge-like means for more or less permanently securing the loop I for pivotal movement (at one end I3 thereof) to one extremity No of the lace I4.

As is shown in Figure 5, the lace I4 may be a shoe lace and the eyelet I5 may be one of the top pair of eyelets in a shoe, designated generally at IT. The knot I6 on the lace end Me is, of course, concealed from view and only the portion of the lace I4 at that end which actually envelops or doubles over the loop It! may be seen by the observer. The remainder of working portion I 4?) of the lace I4 is passed through the eyelet I5 and then the remaining shoe eyelets in the usual manner, ultimately passing through the top eyelet I 8, opposite the top eyelet I5, to furnish a free lace end I4c opposite the knotted end I4a.

As can be seen, the free end I40 of the lace I4 cooperates with the slide II. The slide II, like the loop I0, consists of thin thread-like or striplike material shaped to form a generally elliptical rigid frame. The slide II, however, has over-all dimensions sufficiently small to permit free passage thereof through the central aperture I2 of the loop Ii]. The pivotal mounting of the loop I0 upon the lace I4 at the loop end I3 facilitates the free cooperative movement of the slide II back and forth through the aperture I2, when such is desired.

At the end I9 of the loop I0, longitudinally opposite to the lace fastened end I3, the loop Iii has a restricted or narrowed generally longitudinal outward extension, which affords a substantially narrowed aperture portion I2a. The aperture portion I2a is narrower than the width of the slide II so that the slide II may not pass freely therethrough (at least not without twisting or turning the slide II endwise).

The slide II is a buckle-like member having a centrally positioned integral cross-piece 20 extending laterally of the elliptical body of the slide II so as to define two subtantially semi-elliptical apertures 2| and 22 on opposite sides of the cross piece 20. As can be seen, at the free end Me of the lace I4, the lace I4 is placed astride the cross piece 20 so as to loop wrap or substantially envelop the cross piece, 20. In so doing, it will be noted that the lace I4 may be considered as two parts or lines, viz., the free or manually graspable end I4c and the working portion I4b (which, in any given assembled position, as in Figure 4, extends from the lace point of contact with the loop end I3 to the lace point of contact with the cross piece 20).

As can also be seen readily from Figures 4 and 5, the apertures 2I and 22 in the slide I I are not substantially larger, in cross-sectional area, than the lace I4 itself. The free end I40 thus has some drag or frictional retention in passing through the outer slide aperture 2| and the working portion I4b, likewise, has a certain amount of drag in passing through the inwardly positioned slide aperture 22. As will, of course, be appreciated from the entire disclosure, the instant device operates to a substantial extent on the basis of the physical laws involving friction. The locking effect obtained, which will be described hereinafter, must necessarily depend upon the relative- 1y high frictional characteristics of laces and the like as well as the relatively sharp turning or crimping of the lace I4 passing through the slide apertures 2| and 22. The slide II thus tends to remain in a given position on the lace I4, although it is clear that such resistance to motion may be readily overcome by exertion of manually applied forces for adjustment of the slide I I upon the lace I4.

As is shown in Figure 5, a shoe lace tip 23 is preferably mounted at the extremity of the free lace end I4c, not only for the purpose of holding the lace fibers together during ordinary wear and tear but also to prevent the slide II from being removed or lost from the free lace end I40. As can be seen in Figure 5, the tip 23 is larger than the apertures 2I and 22 and could not pass therethrough. Such is a preferred arrangement for the instant fastening means.

Referring again to Figure 4, wherein the cooperation among the various elements is best brought out, it will be seen that the fastener is assembled by passing the slide I l, looped by the lace I4, upwardly through the central loop aperture I2 and then outwardly to the left over the restricted loop aperture portion I2a. Pulling upon the lace lines I40 and I4?) causes the slide II to be urged to the extreme outward end of the restricted aperture portion I2a. Merely manual pulling on the manually graspable lace end He causes sliding of the lace I4 through the slide apertures 2I and 22 and over the cross piece 20 until the working lace portion I4!) is tensioned; then such manual pulling results in pull being exerted by both lace lines I41) and Me, which in turn results in outward slide movement as described.

It should also be noted that the loop end I9 (defining the restricted aperture portion I2a) is so designed for cooperation with the slide II that it affords a pivot point support for the slide II as at x, inwardly of the cross piece 20, so that the downward force component of the pull upon the lace lines I40 and Nb will not cause the slide to be pulled through the loop I0. Movement in the direction of the arrow in Figure 4, is of course, accomplished by manually grasping the slide II and urging the same inwardly, out of locking position, and through the central aperture I2. Manual lifting of the outer extremity of the slide I I will, of course, cause slidable pivoting of the same forward of the cross piece 20, so that the cross piece 20 is lifted out of crimping engagement.

In contrast, manual pull upon the fre lace end I 40 causes, first, tensioning of the working lace portion I 4?) and, then, outward movement of the slide II, which is afforded slidable pivotal support inward of the cross piece 20 by the loop end l9. Eventually, the slide II moves a short distance to the extreme outward edge of the loop end I9 and there the slide II is locked in position by frictional forces, as will be readily understood. The free lace end He is crimped between the cross piece 20 and the loop end I9 and also between the working lace portion I41) and the loop end I9. Tensioning on either of the lace lines I 40 or I 42) tends only to tighten the lock or to increase the crimping effect, although a sufliciently strong pull on the free lace end He can cause relative movement between the parts. As just mentioned, manual liftin of the outer end of the slide I I also causes relative movement between the parts. the pivotally mounted slide ll moving as a hinge to uncrimp the free lace end I40.

In general, materials employed are such that no appreciable resilient forces are built up in moving the slide I l into locking position so that slight variations or fluctuations in the tension on the working lace portion Mb would not have the effect of permitting the slide H to spring out of locking engagement. The slide H tends to retain its locked position until positive (manual) force is applied to the slide l I itself or to the free lace end M0. The slide H and loop it] may be made of the same or different rigid materials, including synthetic resin plastics, wire, metal strips, wood and the like. The lace l4 may be made of a suitably flexible material such as the fabric-like material of shoe laces, leather or the like.

For example, the embodiment of the invention shown in Figure 6 is a fastening means comprising a hardened plastic loop 24 and a slide 25, adapted for use with a shoe lace 26. The loop 24 has substantially the same inner aperture contour as that of the loop Ii! (of Figures 1-5, inclusive); but the narrowed slide retaining extension 2? of the loop 24 has upwardly extending side walls 21a (here partially hidden by the slide 2:3) which cooperate with the extension bottoms Zlb to define a pair of parallel tracks adapted to slidably engage the slide 25 and guide the longitudinal movement thereof. Also, the bottoms 2la are curved downwardly and outwardly from the loop aperture so as to effectively improve the slide locking operation. In addition, the lace extremity 26a is aifixed to th opposite end of the loop 24 via the small aperture 28 and is doubled over and sewed so as to prevent slippin therethrough, as can be seen.

The slide 25 is similar in shape and design to the slide ll (of Figures 1-5, inclusive), being adapted to pass freely through the central loop aperture but being adapted to be slidably retained in the downwardly arced track provided at the extension 2?. The slide 25 cooperates with the loop 25 so as to be pivotally slidably engaged inwardly of the slide cross piece 29 in response to outward pull on the lace 26 looped about the cross piece 29. In addition, the slide 25 has a roughened, serrated-like tail portion 30 extending outwardly from lace-receiving apertures 3| and 32 separated by the lace-wrapped cross piece 29. The roughened tail portion 31) facilitates manual graspin of the slide 25 and also tends to help retain the lace 2B (in contact therewith, when the slide is pulled to the right in looking position) from sliding too freely during fluctuations in the locking tension on the lace 26 and slide 25.

The arcuate contour of the loop 24 and the slide (and, particularly, the loop extension 21) is substantially that of the region of object, such as a shoe, over which the fastening device is mounted, so as to effect a generally uniform force distribution through the device. Also, the arcuate track of the extension 21 has the effect of creating an increasing outward longitudinal force component of the generally downward force applied to the cross piece 29 by the lace 26 which must extend upwardly through the loop 24 as well as the slide 25 to wrap the cross piece 29.

As can be seen from Figure 6, pull exerted upon the working lace portion 26b and the free lace end 250 thus results in sidewise movement of the slide 26 (to the right) in sliding cooperation with the track defined by the extension bottom 21b and the side walls 27a. As the slide 25 moves into looking position (crimping the lace 26 in substantially the manner described in connection with- Figure 4, the slide tall 39 extends outwardly over the outward extremity of the extension 21, so as to be readily manually graspable. Slidable pivotal contact inwardly of the cross piece 29 is afforded by the extension 21 in substantially the manner described in connection with Figure 4, and forward or. inward movement of the slide 25 in response to inward manual pull on the tail 3t thereof may be used to eifectively push the slide 25 through the central aperture in the loop 24, as shown by the arrow in Figure 6.

Referring now to Figures 7 and 8, which show still another preferred embodiment of the instant invention, it will be seen that the fastening device so disclosed comprises a loop 33 and a slide 34, in this instance adapted to be used with a flexible belt 35 made of a suitable fabric or leather-like material and having substantially greater width than the laces i l and 2t hereinbefore described.

As can be seen, the loop 33 is hingedly mounted at its fastened end 36 by means of a fabric strip 31a wrapped about the loop end 35 and fastened to a fabric base or other suitable retaining means 31, by means of a rivet 38. Again, the general contour of the aperture 39 defined by the loop 33 is similar to the loop apertures hereinbefore described. As can be seen, the central aperture is sufficiently wide to permit the slide 34 to pass therethrough freely without turning or twisting of the slide 34; and at the end 40, which is the slide retaining end, mounted longitudinally opposite to the fastened end 36 of the loop 33, the width of the loop 33 is reduced to less than the width of the slide 34, so as to provide generally parallel longitudinally extending slide supports or extensions for retaining the slide 34 by pivotal sliding engagement inwardly of the cross piece 41 of the slide 34.

In the structure of Figures 7 and 8, the slide 34 is provided with substantially parallel laterally disposed slots 42 and i3, which are separated by the cross piece 4!. As will be appreciated, the slots 42 and "53 are not substantially larger in cross sectional area than the belt 35 which passes therethrough and over the cross piece 4|, for the reasons hereinbefore mentioned in connection with frictional sliding engagement between the slide 3 l and the belt 35..

The working belt portion 35b may actually comprise an extension of the fabric base 31, or it may consist of a separate piece of fabric preferably attached to the fabric base 31 by means (not shown) suitable for such purposes. The working portion 35b extends upwardly through the inner slide aperture 33, over the cross piece 4! and then downwardly and outwardly through the slide slot 42 to define the free, manually graspable end of the belt at 350. By pulling on the belt portions 35b and 350, one moves the slide 34 into locking position at the slide retaining end 40 of the loop 33, in substantially the manner hereinbefore described. It should also be noted that the loop 33 has a slightly arcuate shape in elevation, being arcuately deflected downwardly at the slide retaining end 40, in substantially the same manner and for substantially the same purpose as set forth in connection with the embodiment of the invention shown in Figure 6.

The provision of the slidable fulcrum at the slide retaining end of the loop has several distinct advantages. For example, the slide fabrication is simplified because the slide may have a. symmetrical design on opposite sides of the cross piece, and unfastening of the assembly is substantially simplified. The slide in such an assembly is merely pushed forward and through the central loop aperture to unfasten the same; and the sliding fulcrum does not create such a long lever arm that extensive force is needed to move the same or that extra strength in the slide or loop structure is needed. Such features are of great importance in shoe lacing fastening. Also, better balance of forces can be obtained by the use of a slide having little more to its structure than a frame just big enough to define to strapor lace-sized apertures separated by a cross piece. The outer end of the slide, in looking position, does not extend outwardly any such distance that would permit other forces or objects to interfere with its function. The outer end, and preferably both ends, of the slide extend from the cross piece thereto a distance substantially less than the longitudinal dimension of the loop. Such a slide is light enough in weight, also, to permit it to be retained upon a shoe lace, for example, in a given position by means of a minimum of frictional forces developed by cooperation between the lace and the slide.

From the foregoing disclosures, it can be seen that the loop and slide in each embodiment of the invention may have a variety of shapes and dimensions and may be made of a variety of materials, providing always that the particular coupling and locking action accompanied by the slidable fulcrum support cooperation therebetween may take place as described. Also, of course, the matter of fixing the loop permanently to the particular fabric base or fastened end of a belt, thong or lace may be accomplished by such suitable procedures as sewing, clipping, riveting, tying and the like.

In general, sharp edges in the loop and slide design should be avoided to minimize the wear and tear on the belt or lace, but as has been mentioned, some frictional drag is desirable in the cooperation between the slide and the belt or lace. Increasing the width of the slide cross piece may in some cases be advantageous in that it tends to increase the amount of material of the lace or belt that is bent in being passed through the slide.

Also, it will be appreciated that the instant fastening means is adapted for attaching to various kinds of lace of round or fiat sections, of woven material as well as leather laces which are generally very difficult to tie, particularly,

such laces as the square section lace used with hunting, marching and army shoes, and also flat leather laces.

It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
