Abstract

An adjustable fastener assembly for forming an adjustable loop around a portion of a wearer's body has an elongate member for encircling the body portion and first and second ends. A pair of rings are secured to the first end, and the second end is in releasable threaded engagement through the rings with the free end on one side of the loop. Secondary fasteners such as mateable strips of Velcro.RTM. material are provided on the opposing faces of the free end and face of the loop so that the free end can be secured to the loop. The elongate member may be a belt or waistband, a collar for an animal, or a hat band or sweatband of a cap or hat.

Description

BACKGROUND OF THE INVENTION

The present invention relates generally to adjustable fasteners for tightening body-encircling members around an appropriate portion of a wearer's body, such as adjustable hat bands, belts, animal collars and the like.

Belts, animal collars and similar straps for encircling a wearer's waist or an animal's neck typically have a buckle at one end through which the other strap end is threaded and adjustably secured. The free end of the strap typically lies loosely on the outside of the loop formed by the fastened belt. Various types of buckles are known, and most consist of one or more rings of metal or the like, through which the free strap end is drawn, tightened, and then secured. Similar fastening devices are used for adjusting the fit of a hat by selectively reducing or increasing the diameter of a hat band extending around the internal periphery of the hat. The loose or free strap end can be a problem and may allow the strap to slip back and loosen the band.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a new and improved adjustable fastener assembly for securing in a loop around a portion of a wearer's body.

According to the present invention, an elongate member is provided for encircling a portion of a wearer's body, the elongate member having an inner face facing the body, an outer face, and opposite first and second ends, a pair of overlapping rings secured to the first end of the elongate member, the second end comprising a strap for releasable threaded engagement through the rings with a free end portion of the strap projecting out of the rings, whereby a loop is formed for releasably fitting around the body portion, and a fastener for securing the free end portion of the strap to the loop.

In a preferred embodiment of the invention, the fastener comprises opposing strips of hook and loop type fastener material, such as Velcro.RTM., on opposing surface portions of the elongate member and free end portion of the strap. The strap is threaded through the rings and doubled back on the inside or outside of the loop so that the strips of hook and loop fastener material face each other, and is then pressed against the opposing strip on the face of the loop. By providing the connection on the inner face of the loop, pressure of the wearer's body or hoop tension against the inner flap or end of the strap will tend to hold the opposing fastener devices in place and prevent slipping. This also avoids the problem of having a loose strap end hanging freely on the outside of a loop. In some cases, it is preferable to position the free end of the strap on the outside of the loop, so that the loop can be tightened readily while it is worn. The free end of the strap is securely fastened, so there will be no loose end and the loop will be secure.

The elongate member may comprise a hat band or sweatband extending around the lower peripheral edge of a hat, for example, while the interengageable buckle and strap allow the periphery of the hat to be adjusted to fit the wearer's head. Alternatively, it may comprise a collar for fitting around an animal's neck, or a belt for fitting around a wearer's waist.

The strap end may be threaded in one direction through the center of one of the rings, then around the outside of the second ring and doubles back in the opposite direction through the center of the second ring and back through the first ring to the inside or outside of the resultant loop. Alternatively, the strap end may be threaded through the center of both rings, and back around the outside of one ring and through the center of the other ring to form a secure first fastener mechanism. The free end is then secured to the opposing surface of the loop, forming a second fastener for added security. Preferably, the rings are of non-rigid, flexible but non-extensible material such as fabric, rope, nylon line, and other equivalent materials. This avoids the use of metal and thus reduces the risk of injury to the wearer in the case of impact, and will be more comfortable for the wearer.

This arrangement provides an adjustable fastener for a hat, belt, collar or the like which is capable of securely holding a hat, belt or collar in any one of a large number of adjusted positions, and provides both a desirable appearance and comfort in use. The combination of overlapping loops forming a buckle with a secondary fastener on the inside or outside of the loop provides the required strength to prevent slipping and loosening after the fastener is secured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 of the drawings illustrates a hat or cap 10 having an adjustable fastener assembly 12 for adjusting the periphery of the cap to fit around a wearer's head. Although the hat illustrated is of the baseball cap type, it will be understood that the same adjustable fastener assembly may be used on other styles of hat in an equivalent manner. The cap 10 includes a head-covering crown portion 14, a front visor 16, and an adjustment opening 18 at the rear. A sweatband 20 or the like extends around the internal periphery of the cap adjacent its lower edge, and the adjustable fastener assembly 12 comprises interengageable end portions projecting from opposite sides of the opening 18, one of the end portions comprising a buckle 22 and the other end portion comprising a strap 24 for threaded engagement through the buckle.

The buckle comprises a pair of overlapping inner and outer rings 25, 26 which are each secured to a strap loop 28 which is attached by stitching or the like to one side of opening 18. The rings 25, 26 are preferably of a non-rigid, non-extensible material such as fabric, rope or the like. Strap 24 is secured at one end to the opposite side of opening 18, or may comprise an extension of hat band 20. The free end of strap 24 can then be threaded through the overlapping rings and doubled back to the desired extent so that the resultant loop is a close fit over the wearers head. The strap is threaded through the rings so that the free end of the strap is on the inside of the resultant loop, rather than on the outside as is conventional in buckle fasteners. A secondary fastener is provided between the free end of the strap and the inside of the loop by means of mateable strips 29, 30 of hook and loop type fastener material on the inside of hat band 20 adjacent the opening 18 and on the inner face of the strap 24 adjacent its free end 32, as best illustrated in FIG. 2. The hook and loop type fastener material is preferably Velcro.RTM.. Other types of interengageable fastener devices may be provided, such as snap fasteners or the like, although Velcro.RTM. is preferred since it will be more comfortable for the wearer and will provide a larger degree of adjustability and make it easier to adjust the amount of overlap between the two strips.

The manner in which the strap 24 is threaded through the overlapping rings and doubled back on the inside of the resultant loop or ring is best illustrated in FIG. 1. The strap is first threaded through the center of the first or inner ring 25, then around the outside of outer ring 26 before doubling back through the centers of both ring 26 and ring 25 to be located on the inside of the resultant loop. The strap is pulled through the buckle before tightening to a sufficient extent to achieve the desired loop diameter. The buckle rings are then tightened to grip the doubled over portion of the strap, and the resultant free end portion is pressed against the inner face of the loop so that the Velcro.RTM. strip 29 is pressed against the opposing Velcro.RTM. strip 30 to secure the free end of the strap to the inside of the loop.

This forms a compact, comfortable and secure fastener of attractive appearance which can be adjusted quickly and easily as needed. The tension on the loop and the radial pressure of the wearer's head against the overlapping Velcro.RTM. strips will tend to make the connection even more secure, rather than tending to loosen the fastener as is the case with equivalent buckles where the free strap end is on the outside of the loop. Also, there are no free strap ends on the outside which would otherwise tend to give a more untidy appearance to the adjustable fastener. Since the loops are of fabric or like non-rigid material, there will be no uncomfortable metal buckle parts pressing against the wearer's head, and the loops can be made of any desired fabric color to match or coordinate with the remainder of the cap and the strap 24 and strap loop 28.

Although the adjustable fastener assembly is described above in connection with adjustment of the size of a cap or hat, it may be used with any item of clothing or the like which is intended to encircle a portion of a wearer's body, in order to provide size adjustment. FIG. 3 illustrates an alternative embodiment of the invention in which the adjustable fastener assembly forms an integral part of a belt or collar 40 for adjustable engagement around the waist of a wearer or the neck of an animal, respectively, rather than part of a hat or cap. In this embodiment, an elongate strap or belt 40 has a loop 44 at one end in which a pair of overlapping inner and outer rings 45, 46 are secured to form a buckle, and an opposite free end 48 for threading through the rings 45, 46 to form a continuous loop, in an equivalent manner to fastener assembly 12 of the previous embodiment.

As in the previous embodiment, a first strip 50 of hook and loop fastener material is provided on the inner face of the strap adjacent the free end 48, and an opposing strip 52 of mating hook and loop fastener material is provided on the inner face of the loop formed by the belt or strap at a location adjacent the fastener assembly. The rings 45, 46 are also of non-rigid, non-extensible material such as fabric or rope as in the previous embodiment. In the case of an animal collar, an additional ring 41 will be secured to the strap adjacent the fastener assembly for holding identification tags, license tags and the like, and for attachment of a lead as necessary, as indicated in dotted outline in FIG. 3.

In order to secure the belt or collar around a waist or neck, after looping the belt around the desired region, the free end 48 of the belt is threaded through the center of ring 45, then around the outside of ring 46 and back through the centers of rings 46 and 45, as best illustrated in FIG. 4. The free end 48 is then located on the inside of the loop formed by the belt. The free end 48 is pulled through until the desired tightness is achieved, the buckle is tightened, and free end 48 is then pressed against the underlying inner face of the loop as illustrated in FIG. 4, so that the mating Velcro.RTM. strips 50 and 52 are engaged.

This arrangement avoids the inconvenience of a free strap end lying on the outside of a belt or collar, and also provides a secondary fastener between the opposite ends of the belt for added security. The arrangement is such that radial force on the inside of the belt will tend to tighten, rather than loosen, the buckle and Velcro.RTM. attachments. The fabric or rope buckle rings will be more comfortable than the conventional metal buckles generally used on belts and collars, and will have a more attractive appearance.

FIGS. 5 and 6 of the drawings illustrate a fastener assembly 60 according to a second embodiment of the invention used to adjust the size of a cap or hat, for example a baseball style cap 14 as illustrated in FIG. 1. Sweatband 20 extends around the inner periphery of the cap adjacent its lower end, as indicated in FIG. 6. In this embodiment, the strap direction is reversed, and the free end of the strap is located on the outside of the cap, rather than on the inside as in the first embodiment. As in the first embodiment, the fastener assembly 60 can be used to adjust the periphery of the cap to fit around a wearer's head. However, unlike the first embodiment, assembly 60 can be adjusted while the hat or cap is worn, so that an accurate fit is easier to achieve.

The adjustable fastener assembly 60 comprises interengageable end portions 62, 64 projecting from opposite sides of opening or cut-out 18 at the rear of the cap or hat, one of the end portions having a buckle 65 and the other end portion comprising an elongate strap 64 for threaded engagement through buckle 65. Buckle 65 comprises a pair of overlapping inner and outer rings 66, 67 which are each secured to strap loop 68 which is attached by stitching or the like to one side of the opening. The rings 66, 67 are preferably of a non-rigid, non-extensible material such as fabric, rope, or the like, although they may alternatively be of metal, rubber, or plastic material.

The free end of the strap 64 is threaded through the rings and then doubled back to the desired extent so that the resultant periphery or loop of the cap is a close fit around a wearer's head. In this embodiment, the strap 64 is threaded from the inside to the outside of the loop, so that it is on the outside, rather than the inside, of the resultant loop. A secondary fastener is provided between the free end of the strap and the underlying outer surface of the strap or loop. Preferably, the secondary fastener comprises mating strips 69, 70 of hook and loop type fastener material such as Velcro.RTM.. One strip 69 is provided on the outside of strap 64 adjacent the end of opening 18 and the other strip 70 is provided on the outside of the strap 64 extending up to free end 71, as best illustrated in FIG. 6. A buttonhole 72 is provided in the cap adjacent the opening 18, so that the free end 71 of the strip can feed back to the inside through buttonhole 72, so that there is no loose or free strap end. A Velcro.RTM. strip (not visible in drawing) also may be provided on the inner face of sweatband 20 adjacent hole 72, for mating with an opposing portion of strip 70 inside the hole 72.

Although Velcro.RTM. is used for the secondary fastener in the preferred embodiment, other fasteners may be used such as snap fasteners or the like. Additionally, instead of a buttonhole 72 for stowing the free end of the strap, a slot, metal grommet, or the like may be used for stowing the strap end. Instead of a buttonhole 72, a Velcro.RTM. strip may alternatively be provided on the outside of the cap, and the strap 64 is then completely secured on the outside of the hat.

As illustrated in FIG. 6, the free end of the strap 64 is threaded first from the inside of the loop outwardly through the two rings 66,67, and then back around the outside of the outer ring 67 and through the inner ring 66. The free end is then pulled tight until the hat or cap is at the desired tightness around the wearer's head. The projecting strap end is then pressed against Velcro.RTM. strip 69 to secure the free end of the strap to the outside of the loop. The remaining loose end 71 of the strap is then tucked through the buttonhole 72 so that it does not hang free. The Velcro.RTM. strip 70 may extend up to the end 71 of the strap as in the illustrated embodiment or terminate short of end 71.

Threading of the strap end to the outside, rather than the inside as in the first embodiment, is desirable where security and tightness of the hat is essential, such as in vigorous sports or high winds, since the hat or cap can be tightened while on the head for a more accurate fit, and can be re-tightened if necessary without having to first remove the cap from the head. It is not possible to adjust the fastener assembly of the hat of FIGS. 1 and 2 without first removing it from the head.

The fastener assembly 60 of FIGS. 5 and 6 may also be used for the belt or collar of FIGS. 3 and 4, so that the free end of the belt is threaded to the outside, rather than the inside, of the belt loop. Again, this will provide easier access to the adjustment mechanism and allow it to be adjusted readily while the belt or collar is worn. In this case, a slot or buttonhole may be provided on the belt itself for stowing the free end of the belt after threading through the rings and attachment of the Velcro.RTM. strips, or alternatively a metal grommet or the like may be provided for this purpose.

The fastener assemblies of both of the embodiments described above are highly secure against slipping, due to the combination of a two-ring buckle with a secondary fastener securing the free end of the belt to the resultant loop, either on the inside or the outside of the loop. The second embodiment, in which the secondary fastener is on the outside, is more readily adjustable but still provides a secure fastening. At the same time, by making the rings of flexible or non-rigid material, the assembly is more comfortable for the wearer than fasteners employing hard or rigid buckle materials.

Although some preferred embodiments of the invention have been described above by way of example only, it will be understood by those skilled in the field that modifications may be made to the disclosed embodiments without departing from the scope of the invention, which is defined by the appended claims.
