Automatically rewindable wire device

Abstract

An automatically rewindable wire device includes a stationary member having a stationary shaft, and a rotary member mounted rotatably on the stationary member and having a windup portion around the shaft. The windup portion and the shaft confine a space. The windup portion has an opening which is communicated with the space and which is spaced apart radially from the shaft. The device further includes a wire having a first portion fixed to the stationary member and a second portion extending outwardly of the stationary member from the first portion of the wire. The second portion of the wire is wound around the shaft in a first angular direction within the space and then wound around the windup portion in a second angular direction by passing through the opening. The second angular direction is opposite to the first angular direction. A windup spring is connected to the rotary member to urge the windup portion to wind up the wire.
