Rapid safety cord concentrator

Abstract

The present invention provides a rapid safety cord concentrator, and more particularly a cord concentrator, having application in window curtains, which binds the free ends of pull cords, and enables the external force produced at the outset of the pull cords being operated by accident to be transmitted linearly into the cord concentrator. Accordingly, the binding stationary state gripping force of the cord concentrator on the pull cords is easily broke apart, thus causing the cord concentrator to instantly lose its gripping force on the pull cords and rapidly separating therefrom, thereby immediately releasing entangled limbs or torso from the pull cords.

1 . A safety cord concentrator, providing a cord concentrator able to consolidate the hanging free ends of pull cords of a window curtain, comprising:
 a casing provided with a hollow passageway, having a through opening to enable external passage into the casing, and at least one hollowed out assembling portion laterally positioned on the casing;   at least one gripping device, fitted into and assembled to the assembling portion, the middle of the gripping device presents a pivot point, the pivot point enables turning toward the internal direction of the casing to present a tangential pressure mouth, and a pressure-operated bar is fitted to the casing to enable parallel integration therewith, the tangential pressure mouths internally grip the hanging free ends of the pull cords, and the external form of the pressure-operated bar exposes a grasping surface external of the casing.   
     
     
         2 . The safety cord concentrator according to  claim 1 , wherein the tangential pressure mouth is formed at the end of a runout end of the gripping device 
     
     
         3 . The safety cord concentrator according to  claim 2 , wherein a corner joint relationship exists between the runout end and the pressure-operated bar, and pivot shafts are fitted at the corner joint area to serve as a pivot, the pivot shafts are pin connected to pivot holes defined in the assembling portion of the casing, thereby enabling the pressure-operated bar forms a lever function. 
     
     
         4 . The safety cord concentrator according to  claim 1 , wherein the surface of the pressure-operated bar protrudes from the exterior of the casing and forms a drop height. 
     
     
         5 . The safety cord concentrator according to  claim 1 , wherein the working end of the pressure-operated bar is provided with clasp protrusions, which function to engage in clasp grooves defined in the assembling portion. 
     
     
         6 . The safety cord concentrator according to  claim 1 , wherein the gripping devices are two sets assembled to the casing, and the runout end of each of the gripping devices are in reciprocal disposition. 
     
     
         7 . The safety cord concentrator according to  claim 6 , wherein the two gripping devices are each fitted with the pivot shafts, and the operating angles of the runout ends overreach a horizontal line based on the horizontal line between the two pivot shafts. 
     
     
         8 . The safety cord concentrator according to  claim 1 , wherein tangential edges of the tangential pressure mouths are dentate in form. 
     
     
         9 . The safety cord concentrator according to  claim 1 , wherein the tangential pressure mouths are incurvate in form. 
     
     
         10 . The safety cord concentrator according to  claim 1 , wherein the casing is fitted with an electronic caution device, the electronic caution device is provided with a start switch, and the start switch is actuated when the gripping device is displaced. 
     
     
         11 . The safety cord concentrator according to  claim 1 , wherein the exterior of the casing is in the shape of a water-drop. 
     
     
         12 . The safety cord concentrator according to  claim 1 , wherein a tangential pressure surface is provided interior of the casing opposite the working side of the tangential pressure mouth.
