Fastener for garment drawstrings, laces, and the like

Abstract

A fastener connects two strings together, such as the drawstring of sweatpants or the two shoe lace strings ends of respective shoe lace strings in a pair of sneakers. The body of the fastener is made out of a material, such as highly dense polyurethane foam, that is strong, yet flexible, or of a rigid plastic, that is strong, yet flexible. The two strings to be fastened pass through one or more gripping and/or locking holes in the fastener body. When the shoelace is passed through the gripping and/or locking holes, the dense polyurethane foam grips the lace tightly. The free ends are pulled through one or more peripheral slits extending towards, but not all the way to, the gripping and/or locking holes and then bent against the upper outer surface of the disk and locked in place in the respective one or more peripheral locking slits.

DETAILED DESCRIPTION OF THE INVENTION

(15) In this invention, the operational description focuses on the term drawstring. It is noted herein that the terms lace or fabric tie, or even string, can be used interchangeably, as the fastener can be used as well for a variety of garments or other uses such as duffle bags, beach bags, laundry bags, or decorative bands each with their favorite name for a fabric tie. Additionally, a decorative shoe lace can be used as a belt for pants with belt loops holding the drawstring as a belt-type fastener. It is also known that the fastener can be adorned with logos or other decorative indicia, such as a cubic shaped fastener bearing the markings of a gaming dice piece. Sports or entertainment logos and characters can also adorn the fastener.

(16) The preferred embodiment of fastener of this invention is illustrated in FIGS. 1-3.

(17) In FIG. 1, a thick semi-rigid disk 1, such as, for example, a dense polyurethane foam disk 1, has a plurality of centrally located gripping and/or locking holes, such as, for example, two centrally located gripping and/or locking holes 2 and two peripheral locking slits (here shown as slits) 3. Locking slits 3 are sufficiently narrow with sidewalls of slits 3 having a sufficiently high coefficient of friction to prevent loosening of the drawstring while in service of being worn or otherwise used. While the length and width of the slits may vary, the width of the slits 3 are preferably in the range of 1/32 to 1/16 inch in width.

(18) In FIG. 2, disk 1 is shown being threaded through by the aglets 7a of the free ends 7 of a drawstring which is engaged with a garment 9, such as a pair of sweatpants. In this configuration, adjustment of disk 1 relative to string ends 7 is possible even though gripping and/or locking holes 2 grasp string ends 7 aggressively due to the small diameter of gripping and/or locking holes 2 relative to string diameter and the high coefficient of friction and elastomeric nature of disk 1 material. Once adjusted as desired, each free end 7 is bent 90 degrees along the front surface 1a of disk 1 and then engaged in adjacent slit 3 for locking with high pull-out resistance (as shown in FIG. 3). End aglets 7a of the free ends 7 of the draw strings provide a grasping space for the fingers of the wearer of the garment.

(19) FIGS. 4A to 4F and 5A to 5D show that the outer contour of disk 1 can be almost any shape enclosing a significant flat area. Some useful shapes are shown in FIGS. 4A through 4F. It is also noted that more than two peripheral slits are shown for convenience. Any pair can be used; multiple slits on each string end 7 can also be used for even greater security although hardly needed. Similarly, the thickness of disc 1 need not be constant as shown in FIG. 5A. A hemispherical side contour such as at FIG. 5B, a fully spherical shape such at FIG. 5C or even a cubic shape such as in FIG. 5D can be utilized. The locking slits are sufficiently narrow with sidewalls of the slits having a sufficiently high coefficient of friction to prevent loosening of the drawstring while in service of being worn or otherwise used.

(20) FIGS. 6-8 illustrate an alternate embodiment of this invention. FIG. 6 shows disk 10 made of rigid yet flexible plastic with one central hole 12 and a pair of locking slits (long 14 and short 16) on either side of hole 12. Note the median section 17 of disk 10 between slits 14 and 16. To insure excellent pull-out resistance (once locked) with less friction between string free ends 7 and disk 10 than that of the preferred embodiment, free ends 7 are wrapped 360 degrees around median area 17 to compensate. This motion also involves four 90 degree bends of each free end 7 and four series points of squeezing of drawstring in central hole and two slits. Slits 14 and 16 are sufficiently narrow with sidewalls of the slits 14 and 16 having a sufficiently high coefficient of friction to prevent loosening of the drawstring while in service of being worn or otherwise used.

(21) FIGS. 7A and 7B show the two steps of adjusting and locking using disk 10. Step 1 of FIG. 7A involves threading both free ends 7 through central hole 12. This squeezes both free ends 7 against the sides of hole 12 by virtue of the size of the hole and the resiliency of the drawstring material. Disk 10 can be easily adjusted since the grasping action is not too aggressive. The wrapping and locking takes place in step 2 of FIG. 7B as detailed in sub-steps A, B, and C. Peripheral slits are sized to squeeze free ends 7 and provide some pull-out resistance with only a moderate amount of friction. It is the totality of free-end 7 engagement with disk 10 that provides the aggregate amount of disk 10 to drawstring pull-out resistance. This embodiment may be preferable for use on sneakers or sport shoes since disk 10 can be thinner and smaller than disk 1. FIG. 8 shows a front view of the locked configuration.

(22) FIG. 9 shows an embodiment of a fastener 10 with at least one central gripping and/or locking hole 12 and no slit.

(23) FIG. 10 shows the fastener 10 of FIG. 9, shown with a portion of a drawstring extending through central gripping and/or locking hole 12.

(24) FIG. 11 shows an embodiment of a fastener 1 with two central gripping and/or locking holes 2, with no slits, showing portions 7 of a drawstring with aglets 7a extending therethrough.

(25) It is further noted that while FIGS. 1-3 show the fastener made of a compressible material, such as dense polyurethane foam, for example, and FIGS. 6-8 show a rigid plastic material for the fastener, it is noted that the embodiment shown in FIGS. 1-3 can alternatively be made with a rigid plastic, and the embodiment shown in FIGS. 6-8 can likewise be alternatively made with a compressible material, such as, for example, dense polyurethane foam.

(26) FIGS. 12 and 12A illustrate a further alternate embodiment of this invention. FIG. 12 shows disk 10a made of polyurethane foam with one normally closed central locking/gripping hole 12a in the form of an openable slit, and a pair of locking slits (long 14a and short 16a) on either side of normally closed locking/gripping hole 12a. To insure excellent pull-out resistance (once locked) with less friction between draw string free ends 7 with aglet 7a and disk 10a, free ends of draw string 7 are wrapped 360 degrees around median area 17a to compensate, and then inserted in locking slit 14a. Slits 14a and 16a are sufficiently narrow with sidewalls of the slits 14 and 16 having a sufficiently high coefficient of friction to prevent loosening of the drawstring 7 while in service of being worn or otherwise used.

(27) Moreover, it is also noted that while FIGS. 1-3 show pairs of slits of equal length and FIGS. 6-8 show pairs of slits of different lengths, it is noted that the slits of a compressible material of FIGS. 1-3 can alternatively be of different lengths, and that alternatively, the slits of FIGS. 6-8, made of a rigid lightweight plastic material, can alternatively be of equal lengths. Also the user may select whatever slits he or she wants to use, if one or more of the slits gets worn from repeated washing.

(28) In the foregoing description, certain terms and visual depictions are used to illustrate the preferred embodiment. However, no unnecessary limitations are to be construed by the terms used or illustrations depicted, beyond what is shown in the prior art, since the terms and illustrations are exemplary only, and are not meant to limit the scope of the present invention.

(29) It is further known that other modifications may be made to the present invention, without departing the scope of the invention, as noted in the appended Claims.
