Device for collecting cord

Abstract

A device for collecting a cord, includes a housing, in which a cord reel, a driving member, and a control member are received. The housing has a hole for the cord entering the housing and being fastened to the cord reel. The driving member is connected to the cord reel to drive the cord reel to rotate reversely after the cord reel rotates in a direction. The control member has a portion in an opening of the housing to be operated to engage and disengage the control member with the cord reel; the cord reel is free to rotate when the control member is disengaged with the cord reel, and the cord is hold when the control member is engaged with the cord reel.

What is claimed is: 
     
         1 . A device for collecting a cord, comprising:
 a housing having a room therein, an opening, and a hole, wherein both the opening and the hole are communicated with the room, and a cord enters the room via the hole;   a cord reel rotatably received in the room of the housing, wherein the cord has an end fastened to the cord reel to be wound around the cord reel;   a driving member received in the room of the housing for driving the cord reel to rotate reversely while the cord reel is rotated in a direction; and   a control member received in the room of the housing, wherein the control member has a portion in the opening of the housing to be operated to engage and disengage the control member with the cord reel; the cord reel is free to rotate when the control member is disengaged with the cord reel, and the cord is hold when the control member is engaged with the cord reel.   
     
     
         2 . The device of  claim 1 , wherein the cord reel has a first locking portion; the control member has a pressing portion and a second locking portion; the pressing portion is operated to engage and disengage the second locking portion with the first locking portion. 
     
     
         3 . The device of  claim 2 , wherein the pressing member is in the opening of the housing. 
     
     
         4 . The device of  claim 2 , further comprising a holding member received in the opening of the housing for reciprocation, wherein the holding member is moved toward the pressing portion of the control member and engages the pressing portion to hold the control member in a condition which the second locking portion disengages the first locking portion. 
     
     
         5 . The device of  claim 2 , wherein the first locking portion includes a plurality of teeth arranged in a circular pattern on the cord reel; the pressing portion and the second locking portion are located at opposite ends of the control member; and the second locking portion has at least a tooth to engage the teeth of the first locking portion. 
     
     
         6 . The device of  claim 2 , wherein the first locking portion includes a plurality of recesses arranged in a circular pattern on the cord reel; the pressing portion and the second locking portion are located at opposite ends of the control member; and the second locking portion has at least a protrusion to be received in any one of the recesses of the first locking portion. 
     
     
         7 . The device of  claim 2 , wherein the housing is provided with an axle mount; the control member has an axle pivoted on the axle mount to let the control member work like a lever; whereby the second locking portion disengage the first locking portion when the pressing member is pressed. 
     
     
         8 . The device of  claim 1 , further comprising an elastic member urging the control member to make the second locking portion normally engage the first locking portion. 
     
     
         9 . The device of  claim 8 , wherein the elastic member has a main plate and at least an arm connected to the main plate; the main plate is connected to the control member, and the arm abuts against the housing. 
     
     
         10 . The device of  claim 1 , wherein the housing has a positioning pin; and the cord reel has a position hole to fit the positioning pin. 
     
     
         11 . The device of  claim 10 , wherein the positioning pin is provided with a fixing block to rest against an end surface of the cord reel when the positioning pin is inserted into the position hole of the cord reel. 
     
     
         12 . The device of  claim 11 , wherein the positioning pin is provided with a gap to make the positioning pin compressible, whereby the fixing block is able to pass through the position hole of the cord reel. 
     
     
         13 . The device of  claim 1 , wherein the opening of the housing is closer to the hole and away from a center of the housing.
