Automatic winding device for golf towel

Abstract

The present invention relates to an automatic winding device for a golf towel, which can hold a towel out of a case when a user pulls the towel and automatically wind the towel so that the towel is put into the case when the user pulls and releases the towel after using it, thereby providing user convenience.

1 . An automatic winding device for a golf towel comprising:
 a case having upper and lower cases coupled with each other and an outlet;   a spring case rotatably mounted in the case;   a reel spring inserted into the spring case and supported by the case so as to apply a rotational elastic force to the spring case;   a towel having one side coupled to the reel spring and the other side coupled to a knob so that the towel is wound on the spring case and is stored in the case; and   a locking device for preventing reverse rotation of the spring case in a state where the towel is drawn out of the case,   wherein the locking device comprises:   a first track of a circular shape which is formed on the bottom surface of a rolling panel of the spring case in a groove type;   a second track which is formed on the bottom surface of the rolling panel in a groove type and has a diameter larger than that of the first track;   a conversion path of a groove type for connecting the first track and the second track with each other;   a seating part which is formed between the first track and the second track in a recess type;   an approach path of a groove type for connecting the seating part and the first track with each other;   a return path of a groove type for connecting the seating part and the second track with each other;   a ball guide groove formed on the inner surface of the case getting in contact with the rolling panel; and   a ball inserted between the grooves of the bottom surface of the rolling panel and the ball guide groove.   
     
     
         2 . The automatic winding device according to  claim 1 , further comprising:
 a tiered part formed at a boundary point between the second track and the return path in order to prevent the ball from going into the second track from the return path when the ball runs reversely.   
     
     
         3 . The automatic winding device according to  claim 1 , further comprising:
 a tiered part formed at a boundary point between the seating part and the return path in order to prevent the ball from going into the return path from the seating part.   
     
     
         4 . The automatic winding device according to  claim 1 , further comprising:
 a tiered part formed at a boundary point between the approach path and the first track in order to prevent the ball from going into the approach path from the first track.   
     
     
         5 . The automatic winding device according to  claim 1 , further comprising:
 a shaft protruding from the inner surface of the case and inserted into the spring case; and   a reel spring fixing slot formed at an end portion of the shaft to support the reel spring so that an end portion of a middle part of the reel spring is inserted into the reel spring fixing slot.
