Definitions

• the present invention relates to connecting articles by suction-based connectors, in particular, sets of articles of clothing such as socks, gloves, and mittens prior to washing, drying, and/or storing.
• Connecting socks with, for example, a safety pin has the disadvantage of the pin coming open during washing or drying, subjecting the person grabbing a bunch of the socks to potentially being stuck by the open pin.
• connecting with a pin or other means that are not intended to remain on the articles of clothing before and after storage or washing requires storing and finding the connecting means when storage and washing of the clothing are desired.
• a pin or similar connecting means takes significant time to put onto and take off of the articles of clothing.
• Connecting articles of clothing by attaching a snap to the articles has the disadvantage of requiring a male/female-type match to connect the clothing and has the disadvantage of requiring pulling on the clothing to release the snapping mechanism.
• Connecting articles of clothing by a Velcro-type mechanism has the disadvantage of requiring a male/female- type match to connect the clothing and further may harm or adversely affect other clothing in the cleaning process by attaching thereto if not fully engaged or covered during the cleaning process.
• a Velcro-type mechanism has the further disadvantage of requiring pulling on the clothing to release the attachment.
• One embodiment of the present invention includes a first sock, a second sock, a suction cup affixed to the first sock, and a suction-retentive member affixed to the second sock.
• the suction cup and the suction retentive member are configured to be joined to hold together the first and second socks.
• the suction-retentive member can have a substantially flat surface against which the suction cup can be forced.
• the suction-retentive member can be flexible and made of a polymeric material.
• the suction cup can be a first suction cup and the suction- retentive member can be a second suction cup.
• a suction cup can be substantially permanently affixed to the first sock and the suction-retentive member is substantially permanently affixed to the second sock. Likewise, it can be more removably affixed. At least one of the suction cup and the suction-retentive member include an adhesive material that affixes at least one of the suction cup and suction-retentive member to at least one of the first and second socks respectively.
• Another embodiment of the invention is a method of making a pair of socks connectable. One step is providing a first sock and a second sock.
• first and second suction-based components are configured to be connected together with suction.
• the first and second suction-based components can comprise suction cups.
• the first suction-based component can comprise a suction cup and the second suction-based component can have a substantially flat surface against which the suction cup can be forced to connect the first and second socks.
• the affixing steps can involve substantially permanently affixing the first and second suction-based components to the first and second socks, respectively.
• the step can involve a more removable affixing of these components.

• Silicone is resistant to most detergents and bleach, is moldable to any shape, and can be colored or clear.
• Other alternative materials include polyurethanes, vinyl-based polymers, such as, for example, vinyl chloride and vinylidene chloride, and polymeric fluorocarbons, such as, for example, Viton®, which is flexible, chemical resistant, and heat resistant.
• vinyl chloride polymers have a softening temperature close to the upper temperatures of some clothes dryers and very hot water so that a choice of material should be made with the likely upper temperatures of cleaning in mind.
• suitable materials for suction cups 2a, 2b include elastomeric resilient materials having a durometer shore A hardness value ranging from about 40 to about 70.
• cup and base regions of suction cups 2a, 2b are not necessarily entirely integral and uniformly of the same material.
• the cup and base regions of the affixed suction cups 2a, 2b are integral and of the same material, while in other embodiments (not shown), the cup and base regions of suction cups 2a, 2b can be of different material, substantially permanently bonded by suitable means, for example, by welding during molding the two regions separately, or after molding the two regions separately, for example, such as by heat-based welding, solvent-based welding, or adhesive.
• suitable adhesives include vinyl-based, polymeric acrylate-based (e.g., PMMA), and epoxy-based adhesives.
• Suction cups 2a, 2b are not limited to specific designs and dimensions.
• Cup regions 4a, 4b are preferably, but not necessarily, of substantially circular cross- section, but may also be of generally oval cross-section or other suitable geometry.
• cup regions 4a, 4b are shown as substantially circular and may have an outside diameter ranging from about 0.37 inch to about 0.75 inch, and may have a radius of curvature ranging from about 0.5 inch to about 1 inch, although other dimensions can be used.
• the base regions 5a, 5b are not limited to a specific geometry and may be generally or substantially circular, oval, square, or rectangular.
• the suction force that connects the socks 1a, 1b is made by urging together with sufficient force the suction cups 2a, 2b such that fluid, usually air, between the cups 2a, 2b is forced out from between them, and such that one or both of the suction cups are elastically deformed and a fluid seal is formed between them.
• An established, connective suction force will be maintained as long as fluid (e.g., air, other gas, water, or other liquid) surrounding the region between the engaged cups 2a, 2b does not enter that region and equalize the pressure within the region to that outside the region.
• fluid e.g., air, other gas, water, or other liquid
• the connection provided by the cups 2a, 2b is intended to withstand the challenge of washing, drying, and storing the pair of socks 1 for the next use so that a step of matching up separated socks is eliminated (or at least reduced for a group of socks).
• the suction cups 2a, 2b can be substantially permanently affixed to the socks.
• the affixation of the cups 2a, 2b is such that the cups 2a, 2b are intended to remain attached for the expected life of the sock or article of clothing, although the cups could be removed for example by cutting the sock fabric or by cutting off a significant portion of the cups leaving a smaller portion on the socks. That is, the cups 2a, 2b are intended to remain after repeated washing in soaps, detergents, bleaches, fabric softeners, and combinations thereof, at washing temperatures, such as up to about 180 0 F, and after repeated drying at drying temperatures, such as up to about 150 0 F, that is, for the normal life of the sock.
• the cups can be more removably affixed, that is, they can be removed without from the sock without any or substantial harm to the sock or the cup.
• Base regions 5a, 5b of the cups 2a, 2b may be substantially permanently affixed to a sock or other article, for example, by heating and melting a portion of each base region 5a, 5b to flow into the sock fabric if base regions 5a, 5b are made of or include a thermoplastic material, or by a suitable adhesive between base regions 5a, 5b and into the sock fabric.
• thermoplastic material For cups that are made of a thermoplastic material, known heating/melting processes can be used to substantially permanently affix the cups 2a, 2b to the socks 1a, 1b by melting a portion of the base region 5a, 5b to the socks 1a, 1b.
• One such process is ultrasonic welding, in which the surface (not shown) of the base regions 5a, 5b can be, for example, rough or otherwise non-smooth and flat such that the ultrasonic energy melts that surface when pressed against the sock causing the melted thermoplastic material to cool and bond to the sock 1a, 1b.
• thermoplastic member such as a thin disk (not shown) can be placed on the inside of the sock, which can be melted through the sock to the base region 5a, 5b of the cups 2a, 2b to provide the cup-to-sock bond.
• 5a, 5b can be roughened or otherwise prepared or modified (e.g., primed) to enhance adhesion.
• suitable adhesives are those that bond the selected cup material and sock material. Examples include polymeric acrylate-based (e.g., PMMA) and epoxy-based adhesives. Hot melt adhesives can be used as well, such as adhesives made of materials that are the same as or similar to the thermoplastic material of which the cup is made.
• a pinchable release is preferred to a pulling release to minimize stress on the article's fabric.
• the affixation of the cups 2a, 2b is such that the cups 2a, 2b are intended to be removable from and replaceable onto the socks 1a, 1b as desired during the expected life of the socks or another article of clothing without damaging the cups or socks.
• Removable suction cups are readily reusable if one or both socks become unexpectedly damaged before the end of their normally useful life.
• Removable affixation of suction cups 2a, 2b can be accomplished by using suitable known mating fasteners (not shown) such as a post and a removable, engageable clasp similar to that used for pierced earrings such that the post transfixes the fabric from one side of the fabric and is secured by the clasp on the other side of the fabric; a threaded post and a matingly threaded retainer, for example, a male threaded post with a pointed end to facilitate transfixing through the fabric and female threaded retainer that matingly threads onto the threaded post; or a post that does not pierce the fabric but is at least partially surrounded by the fabric and a removable mating cap that affixes to the fabric-covered post after straight insertion or after insertion and rotation.
• suitable known mating fasteners such as a post and a removable, engageable clasp similar to that used for pierced earrings such that the post transfixes the fabric from one side of the fabric and is secured by the clasp on the
• Non-mating, removable affixation means include, but are not limited to, small, spring-biased clamps such as an alligator-type clip, a wire-like element securely affixed to a portion of the suction cup and that can be run through the sock fabric and secured to the suction cup, and other such means as are well known to those of ordinary skill in the art of fasteners.
