1. Field of the Invention
The invention relates to fasteners for clothing. More particularly, the invention relates to an adjustable fastener for a brassiere or similar garment.
2. State of the Art
Many articles of clothing are provided with adjustable fasteners. In particular, brassieres are typically provided with an adjustable fastener for connecting right and left center backs of the garment. These fasteners usually include one or more hooks and multiple eyelets spaced apart from each other so that the snugness of the garment eye can be adjusted by mating the hook(s) with the appropriate eyelet(s).
The known brassier fasteners have several disadvantages. First, being located at the back of the garment, they are difficult to manipulate. Second, the hooks and eyelets are typically made of metal and feel uncomfortable pressing against the back of the wearer. Third, the fastener is typically thicker than the garment to which it is attached and is visible through outerwear as a bump.
Many attempts have been made to provide a brassier fastener which is easy to operate, comfortable to the wearer and less visible. While these fasteners may solve some of the problems described above, they typically do not solve all of the problems and often introduce new problems. For example, in attempting to overcome the problems described above, many brassier fasteners sacrifice stability for comfort. This permits the fastener to accidentally detach. Also, some fasteners which attempt to solve the problem of visibility have actually increased the difficulty in operation of the fastener.
The previously incorporated co-owned U.S. patent discloses an adjustable fastener that includes a male part and a female part, both of which are made of soft pliable, sewable plastic. The female fastener part has three spaced apart openings. Each opening has a broad portion and a narrow portion. The male fastener part has a base with an upstanding riser with a flange at the end of the riser. The flange is dimensioned to fit into the broad portion of each opening in the female fastener part and the riser is dimensioned to fit snugly into the narrow portion of each opening in the female fastener part. The back side of the male fastener part is provided with parallel grooves which enhance gripping when releasing the fastener. Both of the fastener parts have a pair of parallel flanges at one end between which the garment back end is inserted and secured to the fastener part. The fastener parts thus become extensions to the garment and are easily visible as such unless covered with additional material. The fastener parts are preferably attached to the garment's center backs or back straps so that the openings in the female fastener part face the back of the wearer and the riser and flange on the male fastener part face away from the back of the wearer. The back of the female fastener part is preferable covered with fabric and/or bears a trademark or a design.
According to one embodiment, the flange on the male fastener part is substantially circular and has a centrally located nub rising from its surface. The broad portion of each opening in the female fastener part is substantially circular and the narrow portion of each opening in the female fastener part has a nub-receiving well. This structure adds stability to the fastener, preventing accidental unfastening.
According to another embodiment, the flange on the male fastener part is substantially elliptical. The broad portion of each opening in the female fastener part is substantially elliptical and a pair of ears extend between the broad portion and the narrow portion of each opening in the female fastener part. This structure also adds stability to the fastener, preventing accidental unfastening.
According to one method of manufacture, both parts are injection molded and are fastened to brassier center backs by sewing. According to another method of manufacture, the male fastener part is injection molded, but the female fastener part is made from a laminate structure which includes two outer layers and two inner layers. The outer layers are made of a soft fabric material and the inner layers are made of soft plastic. One of the plastic layers has the openings as described and the other plastic layer has thick portions which surround the openings in the other plastic layer to create a space for receiving the male fastener part. The plastic spacer is made by embossing a plastic sheet and the outer fabric layers are made from a single layer which is folded.
It has since been discovered that some of the features of the fastener described in the previously incorporated patent are, in fact, disadvantages. For example, the manner in which the fastener parts are attached to the garment is relatively complicated when it is desirable to make the fastener less visible. In addition, while the fastener is made of soft plastic, its presence is still detectable by the wearer on the wearer's back. Furthermore, the overall size of the fastener parts is relatively large making them more easily seen and felt.
It is therefore an object of the invention to provide an, adjustable fastener for clothing, in particular brassieres.
It is also an object of the invention to provide an adjustable fastener which is easy to operate.
It is another object of the invention to provide an adjustable fastener which is soft and comfortable.
It is still another object of the invention to provide an adjustable fastener which is stable when fastened.
It is yet another object of the invention to provide an adjustable fastener which is concealed when fastened.
In accord with these objects which will be discussed in detail below, the adjustable fastener of the present invention includes a male part and a female part, both of which are preferably made of soft pliable, sewable plastic. The female fastener part has at least one and preferably two or more spaced apart openings. Each opening has a broad portion and a narrow portion. The male fastener part has a base with an upstanding riser with a flange at the end of the riser. The flange is dimensioned to fit into the broad portion of each opening in the female fastener part and the riser is dimensioned to fit snugly into the narrow portion of each opening in the female fastener,part. The narrow portion of each opening in the female fastener part is preferably rectilinear in shape and the riser of the male fastener part is also preferably rectilinear in section. Thus, when the riser is in the narrow portion of an opening in the female fastener part, rotation of the male fastener part relative to the female fastener part is restricted.
The female fastener part is advantageously made of a single thin wall which is sewn to the fabric of the garment. The base of the male part is also advantageously made of a single thin wall which is sewn to the fabric of the garment. The fastener parts are preferably attached to the garment's center backs so that the openings in the female fastener part face the back of the wearer and the riser and flange on the male fastener part face away from the back of the wearer. The back of the female fastener part is covered by the garment and does not need to be covered with any other fabric.
According to one aspect of the invention, the single wall construction of the female fastener part makes it more flexible, less easily seen, and not felt so much by the wearer. According to another aspect of the invention, the female fastener part is provided with a bend between the openings so that it lies flat against the back when the male and female parts are coupled to the tightest position. Without the bend, the free end of the female part would rise up away from the back, calling attention to itself from behind the fabric of a blouse.
According to another aspect of the invention, the center of the riser of the male part is offset from the center of the flange. This allows the flange to be made larger and the narrow portion of each opening in the female part to be made smaller. Together these features make the fastener assembly smaller but more stable.
According to a first alternate embodiment, the flange of the male part is provided with a ramp which increases the frictional engagement between the two parts. This is particularly useful for swimwear and activewear with which a more secure coupling of the fastener parts is desirable.
According to a second alternate embodiment the engaging parts of the male and/or the female parts are provided with nubs which increase the frictional engagement of the parts sufficiently that they will not become disengaged while on a hanger in a retail store, or in transit to the retail store.
According to a third alternate embodiment, the male part is provided with a nub and the female part is provided with a bump which the nub passes over when the parts engage. This increases the stability of the fastener and provides a tactile snap or click when the parts are coupled.
According to a fourth alternative embodiment, the male part is provided with a nub and the female part is provided with a groove which the nub seats in when the parts engage. This increases the stability of the fastener and provides a tactile snap or click when the parts are coupled.
Additional objects and advantages of the invention will become apparent to those skilled in the art upon reference to the detailed description taken in conjunction with the provided figures.

Similarly,
There have been described and illustrated herein several embodiments of an adjustable fastener for clothing, especially brassieres. While particular embodiments of the invention have been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the art will allow and that the specification be read likewise. For example, although the fasteners are preferably made of a suitable plastic which may be attached to the garment ends by sewing, other fastening methods such as ultrasonic welding may be possible. Moreover, while the fasteners are especially intended for use with brassieres, they may be suitable as fasteners for other clothing items. It will therefore be appreciated by those skilled in the art that yet other modifications could be made to the provided invention without deviating from its spirit and scope as claimed.
