Benefits of technology
"The present invention provides a two-way cable winding reel that is low in cost and can be used with wired computer peripheral devices. The reel includes a housing, a rotator, a worm spring, and a cable. The rotator has protrusions on its side facing the housing, and the housing has a movable stopper. The stopper is stuck between two of the protrusions and protrudes through the housing. This design allows for easy winding and unwinding of the cable, and ensures that the cable is always in the correct position."
Problems solved by technology
However, it is a great burden for the user to tie and untie excess portions of the cord over and over again.
However, due to the great dragging force coming from the second end, the first end is subject to detachment from the circuit board.
However, it is extremely difficult and costly to design the proper angle of the grooves so as to stop the rotation of the rotating mechanism again and again.
Further the great bounding force caused by the spring 25 will force the roller to strike the groove furiously, which will damage the groove and cause a breakdown after less than thousand times' rotation.

Embodiment Construction
[0016] The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.
[0017] Referring to FIG. 1, the two-way cable winding reel 100 comprises a cable 110, a rotator 120, a housing (including an upper housing 130 and a lower housing 140), a worm spring 150 and a stopper 160. The cable 110 has terminals 111 at each end. The cable 110 can be any signal transmitting cable or power transmitting cable. The terminals 111 can be any specific type of connector, such as a universal serial bus (USB) or personal system 2 protocol (PS2). Though one end of the terminals 111 can be fixed to a circuit board, it is still operated as a two-way winding reel.
[0018] Referring further to FIG. 2, the rotator 120 mainly is a hollow col...

The present invention relates to a two-way cable winding reel. The reel includes a housing, a rotator, a worm spring, and a cable. The rotator has several protrusions on one side, and the housing has a movable stopper. One end of the stopper forms a pawl that extends between any two of the protrusions. The pawl permits rotation of the rotator in a first direction to extend the cable when a sufficient pulling force is applied to the cable, and prevents rotation of the rotator in a cable retraction direction so long as the pawl extends between the protrusions. The other end of the stopper protrudes through the housing such that a user may engage or disengage the stopper to cause the pawl to disengage from the protrusions and permit retraction of the cable to a desired length.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a cable winding reel, and in particular, to a two-way winding reel. [0003] 2. Description of the Prior Art [0004] Wired devices, such as computer peripheral devices, always drag cords around the user's narrow working space. Some users may tie the unnecessary portion of the cord when the cord is longer than a desired length, and untie it when the cord is shorter than a desired length. However, it is a great burden for the user to tie and untie excess portions of the cord over and over again. [0005] U.S. Pat. No. 6,088,021 discloses a one-way reel structure for accommodating the excess cord to any desired length, in which a first end of the cable within the reel is fixed to a circuit board while the second end of the cable is retractable in length for connecting to a port of a computer or the like. However, due to the great dragging force coming from the second end, the first end is su...
