main body 100, the control means 200, and the connectingmeans 300 are produced into one integral component by injection molding the cord lock of the present invention has decreased production costs and improved productivity. - Since the
control portion 220 of the control means 200 is received by thecontrol space portion 150 of themain body 100 by assembling theelastic means 400 with the connectingmeans 300 and applying a force to the control means 200 in the direction of an arrow A as shown inFIG. 6 , the cord lock of the present invention is easily assembled by anyone. - The cord lock of the present invention has an appearance of a beetle by inserting the
protrusions 211 formed on theupper cover portion 210 of the control means 200 into the throughholes 510 of the decoration means 500 by the interference fit, thereby having an attractive appearance while having a high quality. - The
protuberance 320, which is protruded from the connectingmeans 300, is inserted into theelastic means 400 when theelastic means 400 is assembled with the connectingmeans 300, thereby being capable of firmly assembling theelastic means 400 with the connectingmeans 300. - The reinforcing
protuberances 420 are protruded from both sides of thethrough hole 410 of theelastic means 400, thereby increasing the endurance of theelastic means 400 without any deformation. - The control means 200 is elevated by the elastic force of the elastic means 400, as shown in
FIG. 8 , thereby easily controlling the length of the cord C by an one-touch manner when a user wants to adjust the length of the cord C, which was held by the cord lock of the present invention. - That is, when the decoration means 500 is pressed by the one-touch manner in order to control the length of the cord C, the
third receptor hole 221 of the control means 200 coincides with the first andsecond receptor holes main body 100, as shown inFIG. 7 , thereby being capable of easily adjusting the length of the cord C. - When the decoration means 500 is pressed by the one-touch manner, the
control unit 160 of themain body 100 contacts the surface of the decoration means 500, thereby being capable of more easily and efficiently adjusting the length of the cord C. - As apparent from the above description, the present invention provides a cord lock comprising a main body, control means, and connecting means, which are produced into one integral component by injection molding thereby having decreased production costs and improved productivity. Further, the cord lock of the present invention 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 a cord, thereby being capable of easily adjusting the length of the cord and increasing convenience in use.
- Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
