TECHNICAL FIELD
The present invention pertains generally to closures, and more particularly to a reversible locking garment closure.
BACKGROUND OF THE INVENTION
An object of this invention is to provide a garment closure which can resist high amounts of stress, such as desirable for sportswear, yet still be easily operable, versatile, and aesthetic. A reversible closure is desired to provide increased utility and style. Prior art closures with locking features are typically not reversible. For example, U.S. Pat. No. 6,009,604 (Fildan) discloses a closure involving inserting one or more bars of the male member into corresponding channels of the female member and rotating the members until they are coplanar, thereby locking the closure. The rotation required for this type of closure does not accommodate a reversible garment, as operation in the reverse orientation requires excessive stretching of the garment and would be inconvenient or uncomfortable against the body of the wearer.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to a garment closure which is reversible and includes several locking features. The closure has male and female members, each being attached to one end of the garment. The male member includes a pin positioned at an acute angle to the exterior side of the male member, and the female member includes a corresponding first channel which receives the pin. The acute angle provides resistance to decoupling the male and female members, and allows the closure to function under high tensile stress.
In accordance with an embodiment of the closure, a locking mechanism is included on at least one of the male and female members for resiliently resisting decoupling thereof.
In accordance with another embodiment, the closure has two faces parallel to the plane of the coupling motion of the male and female members. When the closure is closed, the two faces are substantially minor images, and the closure is therefore reversible.
In accordance with another embodiment, the first channel is open to the top of the female member and closed to the bottom of the female member.
In accordance with another embodiment, the male member has a body to which the pin is connected by a web. The female member has a second channel which receives the body and a slit which loosely receives the web. In an embodiment, the second channel is open to both the top and bottom ends of the female member. In another embodiment, the second channel is open along the entire length of the interior side of the female member.
In accordance with another embodiment, the pin has a substantially flat pin face. This feature provides resistance to decoupling the male and female members under tensile stress.
In accordance with another embodiment, the male and female members each include a loop whereon an end of the garment is connected.
In accordance with another embodiment, the acute angle of the pin is between about three and about fifteen degrees.
In accordance with another embodiment, the bottom of the pin is rounded to facilitate insertion into the first channel. Other embodiments, in addition to the embodiments enumerated above, will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the closure and garment therewith.

DETAILED DESCRIPTION OF THE INVENTION
Referring initially to FIGS. 1 and 2, there are illustrated, respectively, exploded front and rear elevation views of a reversible locking garment closure. The closure, generally designated as 20, includes a male member 22 and a female member 30. The male and female members are preferably each a unitary molded piece. When fastening the closure, male member 22 is coupled to female member 30 along the direction of the arrow of FIG. 1. Closure 20 is particularly suited for use with garments such as sport brassieres, swimwear, and lingerie, however its utility is not limited to these applications.
FIG. 3 is a reduced front elevation view of closure 20 in a closed position and connected to a garment 500. Garment 500 has a first end 510 and a second end 520 which are connectable by means of closure 20. Male member 22 and female member 30 have, respectively, male and female exterior sides 26 and 36. First end 510 of garment 500 is connected to male exterior side 26 and second end 520 is connected to female exterior side 36. In the shown embodiment, ends 510 and 520 are connected, respectively, to exterior sides 26 and 36 of closure 20 by feeding the fabric of the garment end through a loop in the exterior side and stitching the fabric of the garment end to itself (as indicated by the dashed lines of FIG. 3). Ends of the garment may be connected to exterior sides of the closure by other methods well known in the art including simply passing the end through the opening for attachment elsewhere on the garment, as in the case of a strap.
Referring again to FIGS. 1-2, male member 22 has a pin 25 which is positioned at an acute angle to male exterior side 26. Female member 30 has a first channel 34 for receiving pin 25 (see FIG. 12). In operation, pin 25 is inserted into first channel 34, thereby coupling male member 22 and female member 30. In this manner, first and second ends 510 and 520 of garment 500 are connectable. First channel 34 is positioned at an acute angle, θ, to female exterior side 36, that acute angle corresponding to the acute angle of pin 25. Therefore, when coupled, male exterior side 26 is substantially parallel to female exterior side 36.
The corresponding acute angles of pin 25 and first channel 34 provide resistance to decoupling male member 22 from female member 30 in the presence of transverse stress. In other words, the angle prevents sudden or accidental removal of the male from the female. The acute angle therefore provides a “self-locking” function. In a preferred embodiment, the acute angle of pin 25 and male exterior side 26 is between about three degrees and about fifteen degrees.
FIGS. 4-10 are, respectively, perspective, front elevation, left and right side elevation, top and bottom plan, and rear elevation views of closure 20. Closure 20 has a first face 40 and a second face 42. When male member 22 and female member 30 are coupled, first face 40 and second face 42 are substantially minor images. The coupling and decoupling motion of male member 22 and female member 30 occurs in a plane substantially parallel to first face 40 and second face 42 (refer to FIG. 1). In other words, closure 20 may be worn with either first or second face 40 or 42 against the body of the wearer without interfering with the fastening operation. Closure 20 is therefore a reversible closure.
FIG. 11 is right side elevation view of female member 30, and FIG. 12 is a cross-sectional view along the line 12-12 of FIG. 11. Female member 30 has a top end 32 and a bottom end 33. In the shown embodiment, first channel 34 is open to top end 32 and closed to bottom end 33 (see also FIGS. 8 & 9).
Male member 22 has a body 24 and a web 29 connecting pin 25 to body 24 (see FIGS. 1-2). Female member 30 has a second channel 35 for receiving body 24 of male member 22. First channel 34 and second channel 35 are connected by a slit 38 which loosely receives web 29. In the shown embodiment, second channel 35 is open to top end 32, bottom end 33, and along the entire length of the interior side 37 (see also FIG. 11).
In an embodiment, closure 20 includes a locking mechanism on at least one of male member 22 and female member 30 to resist decoupling of the male and female members. As shown in FIGS. 1, 8, and 16, male member 22 has a protrusion 50. Female member 30 has an indentation 52 in second channel 35 and near top end 32 (see FIG. 12). When coupling, protrusion 50 is resiliently accepted by indentation 52, into which protrusion 50 locks. Resiliently accepted means that some material deformation is required by female member 30 or male member 22 so that indentation 52 may accept protrusion 50, and that female member 30 and male member 22 regain their original shapes when the locking is complete. The force required to deform female member 30 or male member 22 must therefore be provided to remove protrusion 50 from indentation 52, thereby unlocking the mechanism. This locking mechanism makes an audible “click” when closed, indicated proper functioning of the closure to the wearer.
FIGS. 13 and 14 are enlarged cross-sectional views of female member 30 along the lines 13-13 and 14-14, respectively of FIG. 1. FIGS. 15 and 16 are enlarged cross-sectional views of male member 22 along the lines 15-15 and 16-16, respectively of FIG. 1. Pin 25 has a pin face 27 adjacent to web 29. Pin face 27 is substantially flat (not rounded) and first channel 34 has a corresponding flat surface. The flat pin face and corresponding flat channel surface contact when the closure is under tensile stress, and act to resist decoupling of male member 22 from female member 30. (Decoupling under tensile stress would occur by pulling pin 25 out of first channel 34 through slit 38).
In the embodiment of FIGS. 1-2, pin 25 has a pin bottom 28 which is rounded on all sides to facilitate the insertion of pin 25 into first channel 34.
The various locking functions of closure 20 combine to provide a resistance to decoupling under tensile stress of up to 40 pounds.
Further provided is a reversible brassiere including a reversible locking garment closure 20. The term brassiere is used herein to encompass various support garments such as sport brassieres, swimwear tops, and lingerie.
The embodiments of the closure described herein are exemplary and numerous modifications, combinations, variations, and rearrangements can be readily envisioned to achieve an equivalent result, all of which are intended to be embraced within the scope of the appended claims. Further, nothing in the above-provided discussions of the closure should be construed as limiting the invention to a particular embodiment or combination of embodiments. The scope of the invention is defined by the appended claims.
