Description

[0001] Apparatus for fastening wire [0002]

More particularly, the present invention relates to a wire tightening device, and more particularly, to a wire tightening device that simplifies a configuration by reducing the number of components constituting the device, increases product productivity and durability, To a wire fastening device configured to be easily loosened.

In general, shoes such as athletic shoes are provided so that the shoelace is connected in a zigzag fashion so as to be in close contact with the user's foot size. By tightening the shoelace by pulling it, the adhesion between the shoe and the user's foot is enhanced to enable comfortable walking.

However, in the case of young children or elderly people who are in the lower grades of elementary school or elementary school, loosening their shoelaces is not easy, and in the case of athletes such as climbing and cycling, If the knot or the knot is loosened by an intense movement or by an external object, the loosening of the shoelace should be absolutely prevented, since undesirable results such as recording degradation and safety accidents are caused.

In addition, when resting during a workout, the shoe strap can be easily restored only when the tightened shoelace can be easily loosened. Most preferably, the shoelace can be easily tightened and the shoe strap can be tightly maintained. .

In order to facilitate the tightening and loosening of the shoelace, which is contradictory to the above-mentioned mutual shoe straps, many devices for easily tightening the shoelace have been developed. The applicant of the present invention has proposed a ratchet gear 'Shoelace fastening device' was proposed.

However, although the ease of use is increased as compared with the conventional one, there has been a problem in that an elastic means formed of a thin metal with a " U "shape is separately prepared and the apparatus is assembled through a complicated assembling process.

In addition, when the rotary cover is pulled upward to unlock the shoelace, the elastic means is disengaged from the original position, causing a problem of the product, resulting in a decrease in durability and reliability of the product. To solve this problem, There is a problem that the structure of the housing is complicated and the number of parts is increased and product productivity is lowered.

Meanwhile, in order to solve such a conventional problem, the present applicant has proposed a 'wire tightening device' in Korean Patent No. 10-1438572.

This prior art is configured to include a rotating cover, an intermediate member, a support portion having a coupling shaft such as a bolt, a winding member, and a housing. Although eliminating the separate elastic means reduces production and assembly processes, Since it makes a complicated structure for tightening and loosening the wire, it has high defect rate, low productivity, and operation in a narrow space, which causes breakage in frequent use.

In addition, since the above-mentioned Japanese Patent No. 10-953398 and Japanese Patent No. 10-1438572 use a coupling member such as a bolt having a coupling shaft in the coupling of the apparatus, a driver, which is a separate assembling tool, There is a problem in that it is difficult to connect the upper part and the lower part by using the coupling member.

In addition, there is a problem in that the internal space of the apparatus for tightening and loosening the wire is narrow and the durability of the structure is poor.

In addition, the restricting groove 145 of the rotary member 140 has a structure capable of transmitting the rotational force of the rotary knob part 150 to the rotary member 140 only in forward rotation.

The restricting groove 145 includes a rotation protrusion 145a for transmitting a rotational force when the rotation restricting protrusion 153 of the rotation knob part 150 is engaged when the protrusion is rotated in the forward direction, A slanting surface 145b having an inclination extending from a lower end of the rotation tilt 145a so that the rotation restraining protrusion 153 of the rotation restricting protrusion 153 can ride on and move upward, And a seating surface 145c formed on the upper surface of the inclined surface 145b so that the upper and lower surfaces 153 and 153 can be positioned.

Preferably, a plurality of the constraining grooves 145 are continuously formed.

The rotation restricting protrusion 153 of the rotation knob portion 150 is engaged with the rotation protrusion 145a of the restricting groove 145 by the structure of the restricting groove 145, So that the rotation member 140 is rotated in the same direction as the rotation knob portion 150. [

When the rotary knob part 150 is rotated in the reverse direction, the rotation restricting projection 153 ascends and descends along the inclined surface 145b, and the inclined surface 145b of the restricting groove 145, which is again beyond the seating surface 145c, The rotation member 140 does not rotate and only the rotation knob unit 150 rotates.

When the rotation restricting projection 153 is seated on the seating surface 145c when the rotation knob part 150 is rotated in the reverse direction, the rotation knob part 150 is moved upward The reel restricting protrusion 152 of the rotary knob part 150 is disengaged from the take-up protrusion 133 formed on the upper surface of the reel unit 130 so that the reel unit 130 can freely move .

In this way, in a state in which the reel unit 130 is freely movable in the case unit 120, the user can easily pull the wire wound on the reel unit 130 by gripping both sides of the wire W The length can be adjusted.

Preferably, the rotary knob part 150 is rotatably and stably coupled to the case part 120 only by a structural characteristic without a separate coupling member such as a bolt.

The rotary knob part 150 includes a guide groove 154 so that the knob guide 126 protruded along the outer circumferential surface of the case 120 may be inserted into the rotary knob part 150 when the rotary knob part 150 is rotated in the forward or reverse direction And is formed along the inner peripheral surface.

A plurality of engaging protrusions 155 which are hooked and hooked on the knob engaging protrusions 124 protruding from the outer circumferential surface of the case 120 during forward or reverse rotation are protruded inwardly .

The rotation of the guide groove 154 of the rotation knob part 150 and the rotation of the knob guide 126 of the case part 120 as well as the rotation of the engagement part 155 of the rotation knob part 150 and the rotation of the case part 120 The rotary knob part 150 and the case part 120 can be easily rotated (rotated) by holding the rotary knob part 150 without a separate coupling member such as a bolt by the rotatable coupling structure of the knob- It can be moved and stably coupled to facilitate assembly and separation.

1 to 5, a connection structure and a use state for wire fastening and unfastening of the wire fastening apparatus 100 according to the present invention will be described below.

First, the user mounts the wire fastening apparatus 100 by integrating the base 110 with the object T to which the wire tightening apparatus 100 according to the present invention is to be attached.

At this time, the base unit 110 may be integrated with the surface of the object T by an adhesive, or may be sewn together as necessary. If the object T has a double structure, have.

The case 120 of the wire fastening apparatus 100 is configured such that the fixing member 122 is seated in the mounting groove 112 on the mounting groove 110a of the base 110 and the slide groove 111a by sliding.

At this time, the fitting protrusion 122a formed on the bottom surface of the fixing piece 122 is fitted and fixed in the fixing groove 111a-1 of the slide groove 111a, so that the base part 110 and the case part 120 are stable Respectively.

The reel unit 130 is freely movably disposed on the lower side of the inner space 120a of the case unit 120 and the rotating member 140 is disposed in the inner space 120a of the case unit 120, And an elastic wing pawl 143 is positioned on the upper side so as to be engaged with the ratchet gear 125 of the case portion 120. [

The wire W drawn through the wire inlet hole 123 formed in the side wall of the case part 120 passes through the wire hole 132 in the upper part of the winding body 131 of the reel part 130, So that it can be wound around the body 131.

The jaw protrusions 142 protruding from the bottom surface of the body 141 of the rotary member 140 are hooked on the jaws 127 of the case 120 to be coupled with the rotary member 140, So that the case 120 is stably engaged.
