Abstract

A short wire length wire winding box has a rotary disk driven by a spiral reed being installed in the casing of a receiving groove. The communication wire is at first wound around the pivotal shaft (inner circle), and then is placed in the rotary disk. The rotary disk is rotated so that the communication wire wound around the second ring (outer circle) at the same direction. When the rotary disk is rotated, the inner circle will expand toward the outer circle, and therefore, the communication wire is pulled out directly from the wire wind box. Then the communication wire wound around the pivotal shaft will become more and more tighten so that the communication wire on the pivotal shaft will not disperse for avoiding part of the communication wire can not be rewind.

Description

FIELD OF THE INVENTION

The present invention relates to a short wire length wire winding box, and especially to a wire wind box, wherein a communication wire can be tightly positioned to the wire outlet of a pivotal shaft.

BACKGROUND OF THE INVENTION

Currently, many electronic devices, such as computers, modems, telephones, facsimile machines, etc., have communication wires are electrically connected to other devices. However, too long or too many communication wires are often not practical. There are many wire wind boxes for communication wires are commercially sold, referring to FIGS. 1 and 2. A prior art short wire length wire winding box is illustrated. This prior art wire wind box includes a

casing

10 a, a rotary disk 11 a, a communication wire 12 a and a spiral reed (not shown). The casing 10 a having a receiving groove 13 a therein. The receiving groove 13 a is installed with a pivotal shaft 14 a. The lateral sides of the pivotal shaft 14 a and the casing 10 a are installed with

wire outlets

15 a and 16 a.

The

rotary disk

11 a is received in the receiving groove 13 a and is pivotally engaged to the pivotal shaft 14 a for rotation. One lateral side thereof is installed with a ring 17 a. The ring 17 a is installed with a slot 18 a. One wire end of the communication wire 12 a passes through the wire outlet 15 a of the pivotal shaft, while other part of the communication wire is firstly bent through a proper angle and then is pulled to the slot 18 a of the ring 17 a. Then it is protruded out from another wire outlet 16 a of the casing 10 a. When the rotary disk 11 a rotates, the communication wire 12 a may wind on the ring 17 a to slide at a proper time so as to be wound around the pivotal shaft 14 a and the ring 17 a. The spiral reed (not shown) is used to provide restoring elasticity to the rotary disk 11 a.

However, since as the

communication wire

12 a is pulled out directly from the wire wind box, the communication wire 12 a wound on the pivotal shaft 14 a (inner circle) will become looser and looser by a further pulling force, i.e., the communication wire 12 a on the pivotal shaft 14 a will disperse (referring to FIG. 2) so that part of the communication wire 12 a on the inner circle is difficult to be received. Therefore, other positioning device (not shown) is necessary for positioning the communication wire 12 a on the pivotal shaft 14 a.

Furthermore, since as the

communication wire

12 a is wound back to the wire wind box, the pivotal shaft 14 a (inner circle) and the ring 17 a (outer circle) are wound by the communication wire 12 a. The inner and outer circles need spiral reeds and thus, the spiral reed needs a large elastic force. Moreover, a large friction force is formed between different parts of the communication wire, and thus different parts of the communication wire 12 a will hind by one another.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a short wire length wire winding box having a rotary disk driven by a spiral reed being installed in the casing of a receiving groove. The communication wire is at first wound around the pivotal shaft (inner circle), and then is placed in the rotary disk. The rotary disk is rotated so that the communication wire wound around the second ring (outer circle) at the same direction. When the rotary disk is rotated, the inner circle will expand toward the outer circle, and therefore, the communication wire is pulled out directly from the wire wind box.

Then the communication wire wound around the pivotal shaft will become more and more tighten so that the communication wire on the pivotal shaft will not disperse for avoiding part of the communication wire can not be rewind. Furthermore, the communication wire on the pivotal shaft (inner circle) can be tightly positioned on the pivotal shaft without any positioning device. When the communication wire is wound in the box, only the second ring is wound on the communication wire and therefore, only the second ring needs to use the spiral reed. Therefore, the spiral reed needs only a small elastic force and thus the friction force to the communication wire can be reduced effectively. The condition that the communication wire being wound by itself will not occurs.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 3 and 4, the short wire length wire winding box of the present invention is illustrated. The short wire length wire winding box includes a [0019] casing 1, a rotary disk 2, a communication wire 3 and a spiral reed 4. The casing 1 is formed by a first casing half 10 and a second casing half 11 so as to be formed with a receiving groove 12. A pivotal shaft 13 is installed in the receiving groove 12. The lateral sides of the receiving groove 12 and the casing 1 are installed with wire outlets 130, and 120. The receiving groove 12 is further installed with the rotary disk 2. The rotary disk 2 has pivotal hole 20 so that the pivotal shaft 13 is engaged therein for rotation. The two lateral sides are installed with a first ring 21 and a second ring 22. The first ring 21 is installed with a hook groove 210. Thereby, one hook end 41 of the spiral reed 4 on the bearing seat 40 at the outer side of the rotary disk 2 can be hooked thereto so that the spiral reed 4 is installed between the casing I and the rotary disk 2 so as to provide a restoring elasticity. The second ring 22 is installed with a slot 220.
One end of the [0020] communication wire 3 passes through the wire outlet 130 of the pivotal shaft 13, and then winds around the pivotal shaft 13 through several turns. Then, it is placed in the rotary disk 2. Then, the rotary disk 2 is rotated so that the communication wire 3 passing through the slot 220 of the second ring 22 is wound on the second ring 22 in the same direction (referring to FIGS. 5 and 6), and then the wire protrudes from another wire outlet 120 of the casing 1. Furthermore, the hook end 41 of the spiral reed 4 is hooked to the hook groove 210.′
The two wire ends of the [0021] communication wire 3 may be assembled to various connecting plug or other device according to the communication device to be used, such as the sound source plug 31, or the earphone and hand-free earphone 32 having a microphone, the referring to FIG. 3.
Therefore, the [0022] communication wire 3 directly passes through the pivotal shaft 13 and then is pulled out from the pivotal shaft 13. Then, it is wound around the second ring 22 using the same way. Furthermore, the communication wire 3 on the pivotal shaft 13 will expand outwards. When the communication wire 3 is pulled out, as shown in FIGS. 7 and 8. When the wire is pulled away from the second ring 22 having a large diameter, the communication wire 3 winds around the pivotal shaft 13 having a smaller diameter.
Thereby, a wire wind box illustrated in FIG. 3 is formed. In practical application, the wire wind box can be used to receive a length of the [0023] communication wire 3 and the communication wire can be received at any time. A user may insert the plug 31 of the communication wire 3 to a correspondent receptacle of a communication device for providing a download information. The communication wire 3 is pulled out directly from the wire wind box and is pulled by the spiral reed 4 so as to retain a predetermined restoring force so that the communication wire 3 can be successfully rewound to the wire wind box. No wire is exposed out or wound.
Besides, to avoid to be affected by a winding tension as the [0024] communication wire 3 is rewound, the periphery of the rotary disk is installed with a plurality of buckling grooves 23. A free swing piece 16 is installed adjacent to the rotary disk 2 and a freely rotary ratchet 17. By the special reaction between the swinging piece 16, ratchet 17 and the buckling grooves 23, the communication wire 3 can be pulled or released repeatedly for fixing or rewinding.
In the present invention, the [0025] communication wire 3 is at first wound around the pivotal shaft 13 (inner circle), and then is placed in the rotary disk 2. The rotary disk 2 is rotated so that the communication wire 3 wind around the second ring 22 (outer circle) at the same direction. When the rotary disk 2 is rotated, the inner circle will expand toward the outer circle, and therefore, the communication wire 3 is pulled out directly (referring to FIG. 7) from the wire wind box. Then the communication wire 3 wound around the pivotal shaft 13 will become more and more tighten so that the communication wire 3 on the pivotal shaft 13 will not disperse for avoiding part of the communication wire 3 can not be rewind. Furthermore, the communication wire 3 on the pivotal shaft 13 (inner circle) can be tightly positioned on the pivotal shaft 13 without any positioning device.
Moreover, in the present invention, when the [0026] communication wire 3 is wound in the box, only the second ring 22 is wound on the communication wire 3 and therefore, only the second ring 22 needs to use the spiral reed 4. Therefore, the spiral reed 4 needs only a small elastic force and thus the friction force to the communication wire 3 can be reduced effectively. The condition that the communication wire 3 being wound by itself will not occurs.
Furthermore, referring to FIG. 9, another embodiment of the present invention is illustrated. In this embodiment, the [0027] pivotal shaft 13 in the receiving groove 12 is separated. The pivotal shaft 13 and the receiving groove 12 of the casing 1 are separated. One end of the pivotal shaft 13 is connected to a buckling body 131. A respective buckling groove 111 are installed in the receiving groove 12 of the casing 1. The buckling body 131 and the buckling groove 111 are engageable so that the pivotal shaft 13 can be assembled to the receiving groove 12 of the casing 1. Since the pivotal shaft 13 is separable, the communication wire 3 can be wound around the pivotal shaft 13 firstly at the outer side of the casing 1. Then, the pivotal shaft 13 is assembled to the receiving groove 12 of the casing 1 so that the winding operation is easy and convenient.
Moreover, with reference to FIG. 10, a further embodiment of the present invention is illustrated. In this embodiment, the [0028] casing 1 is formed by a first casing half 10, a second casing half 11 and a middle seat 18 so as to have two receiving grooves 12 which are arranged at two surfaces of the middle seat 18. Each receiving groove 12 is installed with a pivotal shaft 13. Each pivotal shaft 13 is installed with a wire outlet 130. The two wire outlets are communicated with one another. The lateral side of the casing 1 is installed with two wire outlets 120.
Furthermore, two [0029] rotary disks 2 and two spiral reeds 4 are installed in the two receiving grooves 12. The communication wire 3 is installed in the two receiving grooves 12. The middle part of the communication wire 3 is installed at the two wire outlets 130 of the two pivotal shafts 13. Two wire ends of the communication wire 3 are wound around the two pivotal shafts 13 through several turns. Then the communication wire passing through the slots 220 of the rings 2 of two rotary disks 2 are wound around the two rings 22 at the same direction. Then they are penetrated out from the two wire outlets 120 of the casing.
Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims. [0030]
