The male fastener part is substantially spherical in shape and the female fastener part, of thin walled construction, is substantially oval or elliptic in its base portion and substantially circular in its upper portion, also engaging portion. The inner diameter of the upper circular portion of the female part fastener is slightly smaller than the outer diameter of the male fastener part, said upper portion of the female fastener part flexes open, upon downward pressure being applied to the male fastener part against the female fastener part, thus allowing the male fastener part to engage and fasten in place.
Description
- The invention relates to snap fasteners for clothing and snap trap fasteners for clothing.
- Snap fasteners comprise a variety of fasteners, most commonly press button fasteners, mostly of metallic construction, some of plastic construction, lately not so often used in clothing. One of the proposed uses of the snap fastener is to replace regular buttons in a polo shirt, which commonly has three buttons, which could be replaced with the snap fastener of the present invention, increasing the ease for fastening said polo shirt collar.
- Strap fasteners comprise a variety of fasteners being one of the most widely used the hook and loop fastener. One of the hook and loop applications is as a fastener in a men's bathing suit fly, which has a weak holding power and requires an additional fastener around the waist, most commonly a cord and lace fastener, to secure the bathing suit around the waist. The snap strap fastener of the present invention could be used to fasten a men's bathing suit fly. Another suggested use of the snap strap fastener could be as an adjustable snap strap fastener for a jacket cuff. Still another application could be as an adjustable snap strap fastener for shoes or athletic shoes.
- It is an object of the present invention to provide an easy to use snap fastener as a replacement of buttons in a shirt, could be a polo shirt, providing a faster and simpler way to fasten the collar of a polo shirt.
- It is another object of the present invention to provide an easy to engage and disengage snap strap fastener to simplify the way in which a men's bathing suit fly fastens, replacing the commonly used hook and loop fastener which requires an additional fastener for the waist, commonly a cord and lace.
- It is yet another object of the present invention to provide an adjustable snap strap fastener for fastening jacket sleeve cuffs, replacing the hook and loop fastener.
- It is still another object of the present invention to provide an adjustable snap strap fastener for some shoes, being this invention's snap strap fastener less bulky and cumbersome than the hook and loop fastener for shoes.
- The snap fastener of the present invention includes a male fastener part and a female fastener part. One embodiment of the male fastener part is substantially spherical. Another embodiment of the male fastener part is formed by two circular truncated cones joined at the larger diameter base. One embodiment of the female fastener part is substantially oval or elliptical in its base portion, with its upper portion opening of a substantially circular shape, more particularly a truncated elliptical cone. The circular opening of the upper portion comprises preferably at least two substantially semi oval notches, on opposite sides. Another embodiment of the female fastener part is a truncated circular cone. Said circular cone, has its upper portion opening substantially circular in shape. This circular opening comprises at least four semicircular notches on opposite sides. Both embodiments of the female fastener part are made of a thin walled construction, preferably of a semi rigid plastic material but they may also be made of a more flexible, vinyl or rubber like material or a combination of both materials, and act as a flexible socket.
- The inner diameter of the upper portion circular opening of the female fastener part is slightly smaller than the outer diameter of the substantially spherical male fastener part, whereas upon applying pressure over the male fastener part with one person's finger against the upper portion opening of the female fastener part, said female fastener part flexes thus allowing the male fastener to fall inside said female fastener, forming a fastened bond, resisting lateral pulling forces, releasable upon applying an upward force, hence disengaging the fastener.
- Another aspect of the present invention is a plurality of spaced apart male fastener parts, in a single row, attached to a strip of thermoplastic yarn web or fabric.
- It is yet another aspect of the present invention a plurality of male fastener parts, in a double row, attached to a strip of thermoplastic yarn web or fabric.
- It is still another aspect of the present invention a plurality of female fastener parts, in a single row, attached to a thermoplastic yarn web or fabric.
- It is yet another aspect of the present invention plurality of female fastener parts, in a double row, attached to a thermoplastic yarn web or fabric.
- The spaced apart male fasteners, and female fasteners, attached to a thermoplastic yarn web or fabric, constitutes a snap trap fastener, used in some applications to replace a hook and loop fastener, for a male's bathing suit fly, jacket sleeve cuffs, some shoes.
- One method of manufacturing for the single male fastener part, is by injection molding, preferably in one piece. It might be required to do it in two parts to be joined subsequently by ultrasonic or laser welding means. Also for the female fastener by injection molding, most likely in one piece. Another manufacturing method for the snap strap fastener is to over mold by injection molding, a plurality of spaced apart male fasteners, preferably of polyamide (PA) material, onto a strip of thermoplastic yarn web or fabric also preferably of polyamide material. Also to over mold by injection molding a plurality of spaced apart female fasteners, preferably of polyamide, onto a strip of thermoplastic yarn web or fabric, also preferably of polyamide (PA) material. An additional method of manufacturing the snap strap fastener is to separately mold the male fastener part, by injection molding, with a pin on the base section of said male fastener and also mold by injection molding a small semi spherical cap, (not shown). Subsequently assemble a plurality of male fasteners to a strip of thermoplastic yarn web of fabric, which had previously had by mechanical means, a series of holes punched to it, assemble the caps on opposite sides of the thermoplastic yarn web and join them by ultrasonic welding means. The same method could be used for the female fastener, to separately mold by injection molding the female fastener with two pins on opposite sides of it and also mold by injection molding two small semi spherical caps (not shown). Subsequently assemble a plurality of female fasteners onto a strip of thermoplastic yarn web, which had previously had by mechanical means, a series of holes punched to it, assemble the caps on opposite sides of the thermoplastic yarn web and join them by ultrasonic welding means. An alternative to the ultrasonic welding may be laser welding.
