The illustrated wire binding apparatus 100 includes a differential device 120 having a driving force application unit, a first differential output unit, and a second differential output unit; A first wire winding portion 167 connected to the first differential output portion of the differential device 120; A second wire winding portion (168) connected to a second differential output of the differential device (120); And a fastening operating portion connected to the driving force applying portion.

For reference, a differential gear mounted on an automobile has a first axle shaft as a structure corresponding to the first differential output portion, a second axle shaft as a structure corresponding to the second differential output portion, A drive pinion may be provided as a structure corresponding to a driving force applying portion, and a propeller shaft may be provided as a structure corresponding to the engaging portion.

That is, the basic structure and operation principle of the differential device 120 is similar to a differential gear (differential gear) widely used in automobiles, and a force applied to the driving force application portion by a user's operation is referred to as a first differential output And the second differential output unit.

For this purpose, the engagement portion may be embodied as an operation dial 112 connected to the ring gear 122 of the differential device 120.

The wire binding apparatus 100 may include a latch portion for allowing the operation dial 112 to rotate only in one direction or the first wire winding portion 167 and the second wire winding portion 168 ) In one direction (i.e., in the winding direction).

When the one-way rotation permission state by the latch unit is released, the first wire winding unit 167 and the wires W1 and W2 wound around the second wire winding unit 168 can be loosened do.

For example, the latch portion may include a ratchet formed of gear teeth formed circumferentially along the inner surface of the operation dial, and a latch portion for fixing one tooth of the ratchet. In this case, the release lever may be formed as the latch release portion so that the user can apply a force to the engagement portion to release the tooth fixing.

The latch portion and / or the latch releasing portion may adopt various known prior art structures. For example, one of the structures of the prior patent documents such as US4597543A, JP Digest 60236982A, KR100884486B1, KR100888149B1, P07000208A, US20100139057A1, US7367522B, US5157813 and the like can be applied.

The differential unit 120 includes a ring gear unit 122 as a driving force applying unit, a differential case 121 coupled to the ring gear unit 122, a shaft coupled to the differential case 121, A pair of pinion gears 125 and 126 coupled to the shaft within the pinion gear 121, a pair of side gears 123 and 124 coupled between the pair of pinion gears 125 and 126, And may include first and second axle shafts inserted into both sides of the differential case 121 and coupled to the first and second side gears 123 and 124, respectively.

The tension applied to the first and second wires W1 and W2 is determined by the tension of the first and second wires W1 and W2. As a result, it becomes possible to wear the body properly.

According to the implementation, the wire binding apparatus 100 may further include a differential lock device for prohibiting the differential operation of the differential device 120. [

For example, a differential operation is performed by rotating a pair of pinion gears 125 and 126 by a load difference between the first and second side gears 123 and 124, And a mechanical device for inhibiting the rotation of the pinion gear.

More specifically, the differential lock device may be implemented as a gear engagement device that is engaged with a gear groove of the pinion gears 125 and 126 or a separate braking gear groove provided along the pinion gear shaft by the user's operating force.

Depending on the implementation, the differential device may be replaced with a newly proposed differential structure, such as a spur gear differential (10-2011-0110121).
