Flexible and Adjustable Fastener

Abstract

The invention concerns a closure device for flexible and adjustable fastening between two edges located opposite or crosswise, in particular for footwear, clothing, textile, leathercraft and sportswear, consisting of at least one tongue ( 5 ) and two edges ( 1, 2 ), the tongue ( 5 ) being provided with a hook-and-loop textile ( 7 ) and being linked to a first edge ( 2 ). The invention is characterized in that an elastic portion ( 9 ) is fixed at an anchoring portion ( 8 ) beneath aid first edge ( 2 ), and the other longitudinal end of the elastic portion ( 8 ) is secured to the tongue ( 5 ), and in that the free portion of the tongue ( 5 ) emerges outward of the first edge ( 2 ) through a buttonhole or an outer slot ( 4 ) provided in said first edge ( 2 ), such that by pulling on said tongue ( 5 ), the traction exerted on the tongue ( 5 ) causes an extension of the elastic portion ( 9 ), enabling the tongue ( 5 ) to be extended outside the slot ( 4 ), and to be applied and secured by simple pressure on a complementary catching portion ( 8 ) of an indentation ( 3 ) of one of the two edges ( 2, 1 ), and in that the anchoring portion ( 8 ) beneath said first edge ( 2 ) is arranged at a distance such that it enables a sufficient length of tongue ( 5 ) to be provided beneath said first edge ( 2 ), and in that the elastic portion ( 9 ) should be spaced apart from the slot ( 4 ) in rest position beneath the first edge ( 2 ), so that upon a maximum pull on the elastic portion ( 9 ), the invisible portion of the tongue ( 5 ) located beneath the edge ( 2 ) extends outside the slot ( 4 ) while the elastic portion ( 9 ) neither shows nor passes through the slot ( 4 ), such that the extension of the tongue ( 5 ) enables the fastener to be readily and conveniently and adjusted.

1 . The closing device concerns a flexible and adjustable fastening between two edges opposite to each other or overlapping, in particular for a shoe, clothing, fabric, leather goods and sports items, of the type consisting of at least one tongue ( 5 ) and two edges ( 1 ,  2 ), the tongue ( 5 ) being provided with a self gripping fabric textile ( 7 ) and being attached to a first edge ( 2 ), characterized in that firstly an elastic part ( 9 ) is fixed at an anchorage point ( 8 ) under the said first edge ( 2 ) and the tongue ( 5 ) is attached at the other longitudinal end of the elastic part ( 9 ) and secondly the free part of the tongue ( 5 ) emerges outside the first edge ( 2 ) through an external buttonhole or a slit ( 4 ) formed in the said first edge ( 2 ), so that by pulling on the said tongue ( 5 ), the tension exerted on the tongue ( 5 ) causes an extension of the elastic part ( 9 ), which permits the tongue ( 5 ) to extend outside the slit ( 4 ) and to be applied and fastened by simple pressure on an additional connecting part ( 6 ) of a notch ( 3 ) in one of the two edges ( 2 ,  1 ) and in that the anchorage part ( 8 ) under the said first edge ( 2 ) is placed at a distance such that it provides a sufficient length of tongue ( 5 ) under the said first edge ( 2 ) and furthermore in that the elastic part ( 9 ) must be at a certain distance from the slit ( 4 ) in the rest state under the first edge ( 2 ), so that during maximum tension in the elastic part ( 9 ), the non visible part of the tongue ( 5 ) situated under the edge ( 2 ) is extended outside the slit ( 4 ) without the elastic part ( 9 ) appearing where it passes through the slit ( 4 ), so that the extension of the tongue ( 5 ) permits suitable and simple adjustment and tightening. 
     
     
         2 . A device according to  claim 1 , characterized in that the tongue ( 5 ) is only extended on the additional anchorage part ( 6 ) of the notch ( 3 ) provided on the opposite edge ( 1 ). 
     
     
         3 . A device according to  claim 1 , intended for an edge to edge closure characterized in that it comprises notches ( 3 ) situated opposite to each other on the two edges ( 2 ,  1 ) fitted with additional parts  6  to which the tongue ( 5 ), is applied. 
     
     
         4 . A device according to  claims 1  and  3  intended for an edge to edge closure, characterized in that the notched part ( 3 ) of the edge ( 2 ) extends closer to the slit ( 4 ) so that the tongue ( 5 ), which emerges through the slit ( 4 ) of the edge ( 2 ), is pressed down on the additional parts ( 6 ) of the notches ( 3 ) placed opposite to each other on the two edges ( 2 ,  1 ). 
     
     
         5 . A device according to  claim 1 , characterized in that the tongue ( 5 ) extends over the edge ( 1 ) and passes through a loop ( 10 ) fixed in a notch ( 3 ) produced in the edge ( 1 ) and is pressed down on an additional hooked part ( 6 ) of the notch ( 3 ) produced on the edge ( 2 ). 
     
     
         6 . A closing device according to  claims 1  and  5  characterized in that the slit ( 4 ) is formed in the outer lateral free edge of the said edge ( 2 ) in order to permit the tongue ( 5 ) to be extended and to slide in the loop ( 10 ), then be pressed down on the additional hooked part ( 6 ) formed in the notch ( 3 ) of the edge ( 2 ). 
     
     
         7 . A closing device according to  claim 1  intended for a closure comprising two edges of the overlapping type, characterized in that the buttonholes or the slit ( 4 ) is positioned at a distance from the free part of the edge ( 2 ) and in that the tongue ( 5 ) emerging from the said slit ( 4 ) is applied only to the notched part ( 3 ) of the additional fabric ( 6 ) of the other edge ( 1 ), so that the edge ( 2 ), after closing of the said tongue ( 5 ) passes under the edge ( 1 ).
