with reference to the annexed drawings the preferred embodiments of the present invention will be herein described for indicative purpose and by no means as of limitation . referring now in more detail to fig1 , there is shown a garment element 10 with an access opening 11 in accordance with an embodiment of the present invention typically located adjacent a cuff 12 of an attendant sleeve portion 14 of the garment . the cuff 12 includes at its distal end an elastic cuff band 16 through which the wearer inserts his forehand f in the process of donning the garment . the access opening or aperture 11 is shown herein as a thumb port in an open used configuration through which the wearer selectively inserts his thumb t in the process of donning the garment . although the present description focuses on a thumb port 11 , one skilled in the art would easily understand that the access opening of the garment element 10 of the present invention could be located on any piece of garment for different uses such as providing selective access to a pocket ( not shown ) of an underlying garment or the like without departing from the scope of the present invention . fig2 depicts the garment element 10 with the access opening 11 in a closed unused configuration in which it is substantially invisible to the garment wearer while being generally obstruction less . as shown more specifically in fig3 and 4 , the access opening 11 is typically elongate and is located at a location wherein the garment has first 18 and second 20 fabric ends extending in generally opposite first and second directions . the opening 11 includes an overlap section 22 extending between two opposite longitudinal attachment sections 24 . the overlap section 22 has a first fabric end 18 exterior unfolded portion 26 extending transversely into the first direction and a first fabric end 18 folded portion 28 folded inwardly into the second direction , and a second fabric end 20 interior unfolded portion 30 extending transversely into the second direction and a second fabric end 20 folded portion 32 folded outwardly into the first direction , whereby the folded portion 28 of the first fabric end 18 is at least partially sandwiched between the unfolded 30 and folded 32 portions of the second fabric end 20 and the folded portion 32 of the second fabric end 20 is at least partially sandwiched between the unfolded 26 and folded 28 portions of the first fabric end 18 . the first and second fabric ends 18 , 20 are selectively separable from one another at the overlap section 22 to allow a protrusion such as a thumb t or the like to transversely extend there between . the first and second fabric ends 18 , 20 are attached to one another at the attachment sections 24 using stitching , snaps , buttons , rivets or the like . typically , the stitching of attachment sections 24 secures both the exterior fabric end 18 and the interior fabric end 20 in the above described overlap configuration in the proper place on the cuff 12 . although the stitching of the attachment section 24 located adjacent the free end of the cuff 12 is typically spaced apart inwardly from interior edge of the elastic band 16 by a distance of between about zero and about one inch , preferably about ½ inch . as illustrated more specifically in fig4 , a first fold region 34 defined at an intersection between the unfolded 26 and folded 28 portions of the first fabric end 18 is typically rigidified , and also reinforced , by a stitching 36 , permanent fold line or the like that extends at least partially there along , preferably all along the overlap section 22 . similarly , a second fold region 38 defined at an intersection between the unfolded 30 and folded 32 portions of the second fabric end 20 is typically rigidified by a stitching 40 , permanent fold line or the like . the rigidifying stitching 36 , 40 help in keeping the access opening 11 closed when in the unused configuration by keeping the folding or “ sandwich effect ” thereof . to a certain extent , they also help ensuring a self - sealable opening 11 in the open used configuration by keeping the first and second fabric ends 18 , 20 tight against the thumb t when the later extends there between through the access opening 11 . the free edges 42 , 44 of the respective folded portions 28 , 32 of the first and second fabric ends 18 , 20 are typically nicely terminated and rigidified using conventional seam finishes in the art to prevent deterioration , for example by fraying , tearing or defibering thereof . the seam finishes typically give some rigidity to ensure proper self - closing of the opening 11 and self - sealing thereof in the open used configuration by keeping the first and second fabric ends 18 , tight against the thumb t ( or other protrusion ) when the later extends there between through the access opening 11 , because of their resiliency or “ shape memory ” effect . the rigid free edges 42 , 44 also help keeping the opening 11 closed by having their seam finishes substantially partially gripping to one another when the two fabric ends 18 , 20 are being pulled transversely away from each other . typically , each seam finish includes an edge cover 46 folded over and stitched to the free edge 42 , 44 of the corresponding fabric end 18 , 20 , via stitches 48 . the edge cover 46 could be made out of a similar material than the corresponding fabric or a different material such as but by no means as of limitation a stiffer or reinforced material , and eventually a resilient or stretchable material that could provide a certain seal against water or the like such as rubber , neoprene or the like for more specific use by sailors and / or bikers . the overlapping orientation of the inwardly folded exterior first fabric end 18 over the outwardly folded interior second fabric end 20 are patterned in such a manner as to provide maximal deflection capabilities when the cuff 12 is positioned in a substantially horizontal orientation ( such as during cycling or the like ), in a substantially vertical orientation ( such as during walking or the like ) or anywhere in between . the orientation opposes vertically gravitationally - induced weather intrusions and / or similarly opposes horizontally ( in a rearward direction ) windward penetration induced weather intrusions , respectively . the overlapping configuration is also effective in preventing insects egress into the access opening 11 and serves to efficiently and securely close the thumb port 11 once the thumb t is inwardly retracted there from by making the access opening 11 generally self - closable . fig3 and 4 also disclose the downward orientation of the exterior first fabric end 18 overlapping the interior second fabric end 20 to further illustrate the self - sealable characteristic of the access opening 11 in the closed unused configuration . fig5 is a depiction of the palm side of the cuff 12 illustrating that the second fabric end 20 is part of a typically reinforced fabric 50 extending over the palm surface of the cuff 12 intended to make said cuff 12 more durable and protective to the wearer in the event that the garment is destined for recreational use , use in sport , or labor or the like related application . obviously , the self - closable and self - sealable features of the access opening 11 depend on the aspect ratio of the opening length of the overlap section 22 over an overlap transversal distance between the first and second fold regions 34 , 38 . typically , the aspect ratio is between about two to seven ( 2 - 7 ), preferably about three to five ( 3 - 5 ). although the present invention has been described with a certain degree of particularity , it is to be understood that the disclosure has been made by way of example only and that the present invention is not limited to the features of the embodiments described and illustrated herein , but includes all variations and modifications within the scope and spirit of the invention as hereinafter claimed .
in a garment element , for example a cuff for a sleeve , an access opening is defined between an overlap section extending between two attachment sections , the overlap section being formed of interleaving fabric ends suitably stiffened to provide a self - sealing function in both a use mode in which a body member extends there through and a non - use mode with the opening closed .
