Description

FIELD OF THE INVENTION

Our present invention relates to a button clip, especially for a strapless brassiere and, more particularly, to a clip adapted to clamp onto a garment, e.g. for securing a strap thereto, and having the appearance of a button or the like.

BACKGROUND OF THE INVENTION

While a wide variety of garment fasteners are available, for example, to secure a strap to another part of a garment such as a brassiere, there is a challenge to provide fasteners which not only can function effectively for the purpose but which also have an aesthetic character and can provide a decorative element. Button fasteners are widely used because the portions of the buttons which are exposed can be highly decorative.

In many cases it is desirable to provide a fastener which does not have a part permanently attached to the fabric portion to which a strap or the like is to be affixed. This can be the case of a strapless brassiere which may not have facilities for attachment of a strap and which, in some cases, may be worn by a person desiring a strap for aesthetic or support reasons.

OBJECTS OF THE INVENTION

It is, therefore, the principal object of the present invention to provide an improved fastener, especially for garments and particularly for a strap to be attached to a strapless brassiere, which satisfies the above-mentioned requirements, is convenient to use and is of aesthetic character.

A more specific object is to provide an improved clip-type fastener which is reliable, secure against release and has an aesthetic appearance.

It is also an object of the invention to provide a highly decorative fastener, especially for straps to be optionally affixed to a strapless brassiere.

A further object is to provide a strapless brassiere with an optional strap and clip assembly with reliable attachment of the strap to the strapless brassiere and a pleasing appearance.

SUMMARY OF THE INVENTION

These objects and others which will become more readily apparent hereinafter are attained, in accordance with the invention, in a button clip which comprises a pair of tongues affixed at one end to a pair of plates adapted to straddle the end of a strap and to be welded thereto and a slider shiftable along the tongues and adapted to press the opposite ends together against the fabric of a garment to which the clip is secured. According to a feature of the invention, the slider has the configuration of a button and is generally annular with a central opening through which the surface of one of the tongues can be exposed.

The tongues may be of progressively increasing thickness toward the end engageable with the garment so as to be cammed tightly thereagainst by the movement of the slider at this end.

Advantageously, the confronting surfaces of the tongues at this end are toothed to grip the garment firmly according to another feature of the invention, the ends of the tongues secured to plates are traversed by pins of one of the plates. The portions of the plates secured to the strap, in turn, may be provided with formations facilitating the attachment of these plates to the strap by ultrasonic or thermal welding.

According to a feature of the invention, the tongues and the slide button are of different colors and possibly of different textures so as to enhance the aesthetic effect to the clip. The plates can advantageously be of the same color as the slide button and all of the parts of the button clip can be injection-molded of polyoxymethylene and/or polyurethane as may be desired.

It has been found to be advantageous to define the opening in the slide with a ridge or rim separated by a groove from a wider framing portion of the slide.

The invention also encompasses a strap provided at its ends with a pair of such button clips which can be attached to opposite sides of a strapless brassiere, for example, when the strapless garment is not provided with buttonholes or strap attachments so that the wearer can affix the optional straps to the brassiere if the brassiere is to be worn as a strap brassiere.

The brassiere itself, provided with the straps and clips, is also deemed to be part of this invention.

SPECIFIC DESCRIPTION

As can be seen from FIGS. 1-4 , for example, the button clip of the invention comprises a pair of tongues 10 and 11 which can be pressed together by movement of a slider 12 therealong. The tongues 10 and 11 are formed with ends 13 and 14 adapted to grip a garment and formed with teeth 15 and 16 on the confronting surfaces. The tongues have thicker regions 17 and 18 toward the clamping end and are provided with ramp surfaces 19 and 20 leading to these thickened regions and which are cammed toward one another when the slide 12 is pressed toward the ends 13 , 14 .

At their opposite ends, the tongues 10 and 11 are engaged between a pair of shield-shaped plates 21 and 22 which are provided with formations 23 , 24 along their confronting surfaces for engagement with a strap. The plates 21 and 22 are composed of thermoplastic material and can be ultrasonically or thermally welded to the strap which may also be composed of a synthetic resin filament fabric to facilitate attachment by welding thereto.

The plate 21 is provided with pins 25 extending through holes 26 in the plate 22 (see FIG. 5 ) and through corresponding holes in the tongues 10 and 11 . As is also visible from FIGS. 1-5 , the slider 12 has the configuration of a circular button and is provided with openings 27 and 28 through which the surfaces 29 and 30 of the tongues 10 and 11 are visible. The strap fabric has been represented at 31 in FIG. 5 and from FIG. 5 it is also apparent that the openings 17 and 28 are framed by narrow ridges 32 and 33 separated by grooves 34 and 35 from larger bulges 36 and 37 .

It will be apparent from FIGS. 1-4 that the plates 21 and 22 and the slider 12 are composed of synthetic resin material of one color while the tongues 10 and 11 are composed of a synthetic resin material of another color. These parts have different finishes, for example, smooth and matte finishes, respectively, and can be textured similarly or differently as desired. The preferred material for the clip is polyoxymethylene or polyurethane.

In use the clips are attached to a strap 31 by ultrasonic or thermal welding and the resulting strap can, as has been shown in FIG. 6 , be provided with two such clips 38 and 39 at its opposite ends. The strap can be used to grip opposite sides of a strapless brassiere 40 and in FIG. 6 this brassiere is shown to have a cup 41 and a back strap 42 . The other half of the brassiere and strap 31 has not been shown. The strap and clip assembly may be used when the wearer desires the additional support that such a strap can provide for the strapless brassiere or desires the aesthetic effect that the combination of the fabric strap 31 and the decorative clips 38 , 39 can provide.

The slider 12 can have camming surfaces 43 designed to press the ends 13 and 14 of the clip together against the garment 40 when the slider 12 is displaced in a direction opposite to the arrow 44 to clamp the clip. Arrow 44 , therefore, represents the direction of movement of the slider to open the clip.

FIGS. 7 and 8 show the tongues 10 ′ and 11 ′, slightly exaggerated in an open position and closed position, respectively. As can be seen from FIGS. 7 and 8 , the welding flanges of the button clip having not been shown here, the tongues 10 ′ and 11 ′ can be interconnected at 50 so as to form one piece of a relatively soft material, for example, the polyurethane mentioned earlier. Of course two separate tongues held together by the welding flanges can be provided as well. Between the two tongues and close to the ends which are secured together, a hemispherical formation 51 can be provided to assist in pressing upon tongues when the slide 12 ′ is in its retracted position. When the tongues are closed so that they are clamped on a garment, the hemispherical formation 51 produces a bulge in the tongue 10 ′, adjacent the connection 50 between these tongues.

Another hemispherical formation 52 can be provided on the tongue 10 ′ and can spring into the opening 53 of the slide 12 ′ (compare FIGS. 7 and 8 ), to form a detent retaining the slide 12 ′ in its closed position (FIG. 8 ). The camming surfaces 43 ′ of the slide and the corresponding ramps 19 ′ and 20 ′ of the tongues 10 ′ and 11 ′ may have an angle of inclination to the direction of displacement of the slide which renders the slide frictionally self-locking in the closed position so that the slide is held in the closed position not only by the detent 52 but also by the frictional engagement of these camming surfaces and ramps.

To prevent the slide from shifting along the tongue from the open position when the slide is not being manually displaced, the detent formation 52 can engage the end of the slide turned toward the free ends of the tongue (FIG. 7 ). From this position, when the slide is urged in the direction of the arrow 54 , the slide rides over the detent 52 , pressing the tongues together and locks when the detent 52 engages in the opening 53 . The slide can be of a harder material than the tongues, i.e. the polyoxymethylene mentioned earlier.
