Cord Lock

Abstract

A cord lock for adjusting the length of a cord used in clothes or bags, including: a main body for receiving the cord, including a bottom cover portion, an outer cover portion and an inner portion formed on the bottom cover portion, a control space portion formed between the outer cover portion and the inner portion, and an oval-shaped first receptor hole and an oval-shaped second receptor hole respectively formed through the outer cover portion and the inner portion for passing the cord; control means for adjusting the length of the cord, which had passed through the first receptor hole and the second receptor hole of the main body, including an upper cover portion provided with a plurality of protrusions, and a control portion protruded approximately perpendicularly from the end of the upper cover portion, received by the control space portion, and provided with a third receptor hole for passing the cord; connecting means produced integrally with the control means and the main body by injection molding for integrally connecting the control means and the main body, and provided with a fourth receptor hole for passing the cord; elastic means assembled with the connecting means to hold the cord, having passed through the first receptor hole and the second receptor hole of the main body, for applying an elastic force to the control means, and provided with a through hole, the outer circumference of which contacts a protuberance of the connecting means, so that the elastic means is firmly assembled with the connecting means; and decoration means for covering the outer surfaces of the control means and the connecting means to ornament the outer appearance of the cord lock, and including through holes, into which the protrusions formed on the surface of the upper cover portion of the control means are inserted by interference fit, and a fifth receptor hole, formed through a portion thereof covering the connecting means, which communicates with the fourth receptor hole of the connecting means. The cord lock includes the main body, the control means, and the connecting means, which are produced into one integral component by injection molding, thereby having decreased production costs and improved productivity. Further, the cord lock comprises decoration means, which serves to ornament the external appearance thereof, and is pressed by an one-touch manner so as to release the holding of the cord, thereby being capable of easily adjusting the length of the cord and increasing convenience in use.

1 . A cord lock for adjusting the length of a cord used in clothes or bags, comprising:
 a main body for receiving the cord, including a bottom cover portion, an outer cover portion and an inner portion formed on the bottom cover portion, a control space portion formed between the outer cover portion and the inner portion, and an oval-shaped first receptor hole and an oval-shaped second receptor hole respectively formed through the outer cover portion and the inner portion for passing the cord;   control means for adjusting the length of the cord, which had passed through the first receptor hole and the second receptor hole of the main body, including an upper cover portion provided with a plurality of protrusions, and a control portion protruded approximately perpendicularly from the end of the upper cover portion, received by the control space portion, and provided with a third receptor hole for passing the cord;   connecting means produced integrally with the control means and the main body by injection molding for integrally connecting the control means and the main body, and provided with a fourth receptor hole for passing the cord;   elastic means assembled with the connecting means to hold the cord, having passed through the first receptor hole and the second receptor hole of the main body, for applying an elastic force to the control means, and provided with a through hole, the outer circumference of which contacts a protuberance of the connecting means, so that the elastic means is firmly assembled with the connecting means; and   decoration means for covering the outer surfaces of the control means and the connecting means to ornament the outer appearance of the cord lock, and including through holes, into which the protrusions formed on the surface of the upper cover portion of the control means are inserted by interference fit, and a fifth receptor hole, which if formed through a portion thereof covering the connecting means so as to communicate with the fourth receptor hole of the connecting means.   
   
   
       2 . The cord lock as set forth in  claim 1 , wherein:
 side cover portions are respectively provided on both sides of the outer cover portion and the inner portion to define the external appearance of the main body; and   a control unit for controlling the movement of the decoration means is provided on the upper surface of the outer cover portion.   
   
   
       3 . The cord lock as set forth in  claim 1 , wherein the protuberance is protruded from the periphery of the fourth receptor hole of the connecting means so that the elastic means is firmly assembled with the connecting means therethrough. 
   
   
       4 . The cord lock as set forth in  claim 1 , wherein hinge portions, which have thicknesses larger than those of other members and widths smaller than those of other members so that the connecting means and the control means are located at their normal positions when the control portion of the control means is placed in the control space portion of the main body and the cord is received by the first, second, third, and fourth receptor holes, are respectively provided on a boundary space between the connecting means and the control means and a boundary space between the connecting means and the main body. 
   
   
       5 . The cord lock as set forth in  claim 1 , wherein reinforcing protuberances for preventing the through hole from being deformed are protruded from both sides of the through hole of the elastic means. 
   
   
       6 . The cord lock as set forth in  claim 1 , wherein an insert protrusion, which is inserted into a concave groove of the control means so as not to separate the decoration means from the control means when the decoration means covers the control means and the connecting means by inserting the protrusions into the through holes by interference fit.
