Description

Wire tightening device {apparatus for fastening wire}

The present invention relates to a wire tightening device, and more particularly, to a wire tightening device having improved compatibility.

In general, a wire tightening device is used to adjust an article worn on a part of the wearer's body to fit the wearer's body size. Such a wire tightening device can be variously applied to items worn by adjusting the size through a wire, such as a head wearing device including a hat, a belt, gloves, a bag, snowboarding, and water skiing, as well as shoes.

On the other hand, in shoes such as sneakers, the shoelaces are connected to the instep side in a zigzag form so that they are closely adhered to the size of the user's foot, and by pulling and tightening the shoelaces, the adhesion between the shoes and the wearer's feet is increased, so that comfortable walking is possible. At this time, the pulled shoelace is tied in a knot to fix the tightened state.

At this time, when delicate hand manipulation is difficult, such as a low-grade elementary school child or an elderly person, it is not easy to loosen and tighten the shoelace.

In addition, when excessive force is applied to the shoelace by knotting it, it is difficult to untie it again and readjust it. Conversely, if the shoelace is loosely knotted, it is untied while walking, and there are problems such as tripping on the foot. In particular, if the knot is untied during an exercise such as mountain climbing or bicycle racing, there is a problem in that the risk of injury due to a safety accident as well as a decrease in the record increases.

Therefore, while being able to easily tighten the shoelace, it is required to have a structure in which the shoelace is easily operable to loosen the shoelace when necessary while maintaining it firmly in the tightened state. Accordingly, a number of devices for smoothly controlling opposite tightening and loosening operations of the shoelace have been developed.

1 is a perspective view of a shoe equipped with a conventional wire tightening device.

As shown in FIG. 1, the conventional wire tightening device 5 is fixed to the tongue 1c or upper 1a, 1b of the shoe 1, and rotates or elevates the rotation cover 5a provided on the upper surface side. Depending on the operation, the wire w may be wound or unwound therein.

That is, in a state in which the rotary cover 5a is lowered toward the tongue 1c, the internal components are arranged to engage with each other and rotate. And, when the rotating cover (5a) is rotated, the wire (w) may be wound on a reel unit provided on the inside of the wire tightening device (5), and as the wire (w) is wound, the shoe (1) is placed on the foot. It can be tightened to adhere to the Alternatively, in a state in which the rotating cover 5a is pulled upwards, the internal components are spaced apart from each other, and the wire w may be unwound while the reel unit rotates freely.

However, this conventional wire tightening device 5 can be precisely adjusted only when the process of tightening and loosening the wire w is firmly fixed to the tongue 1c or upper 1a, 1b of the shoe. That is, the problem that the wire w is not properly wound due to the rotation of the wire tightening device 5 by itself by the rotational force should be prevented in advance.

To this end, in the related art, a hole or incision is formed in the tongue 1c or upper 1a, 1b of the shoe 1, and the fixing means provided in the wire tightening device 5 is penetrated and combined, or the bar is sewn through sewing. The fixing method was used.

However, it is difficult for ordinary people to directly perform this fixing method. For this reason, there is a problem in that the user has to purchase the shoes in the state in which the wire tightening device 5 is mounted, or to install the shoes by requesting a professional repair company.

In addition, as a force for rotation is applied to the hole or cutout formed to fix the wire tightening device 5, there is a problem in that the hole or cutout is expanded or torn. For this reason, there is a problem in that the fastening force of the wire tightening device (5) is loosened and separated from the shoe (1), or the durability of the shoe is lowered, thereby significantly shortening the service life.

On the other hand, the tightening object to be described below is preferably understood as an article whose size is adjusted through the tensile force of the wire (w) wound during the rotation operation of the wire winding means 40, and in each embodiment of the present invention, the shoe ( 1) is described and illustrated as the tightening object. Therefore, it is preferable to understand that the one side part and the other side part of the tightening object are both side skins (1a, 1b) of the shoe (1). In addition, it is preferable to understand that the wearable object is a part of the body that is inserted and wrapped in the inside of the tightening object. Hereinafter, the foot will be described and illustrated as the wearing object. Of course, in some cases, the tightening object may be provided as an article such as a hat, gloves, pants, belt, etc. In this case, the head, hand, waist, etc. are the wearable objects.

And, the wire winding means 40 is installed in the shoe 1, and as the wire w passing through the skins 1a and 1b on both sides of the shoe 1 is rotated to be wound inside, the shoe (1) can be adjusted to fit the user's foot size.

In detail, the wire winding means 40 includes a reel part that is selectively engaged with the rotation operation means rotated during a one-way rotation operation. That is, when the rotation operation means and the reel unit are engaged and interlocked, a portion of the wire (w) is wound on the reel unit, and the both sides of the skin (1a, 1b) of the shoe (1) through the tensile force of the wire (w). ) is tightened so that it adheres to the outer surface of the foot. In this case, in a state in which the rotation operation means and the reel part are engaged, rotation in one direction is possible, and a restraining means for selectively restricting rotation in the other direction may be further provided. Since the conventional configuration and operation method of the wire winding means 40 are disclosed in earlier applications and registered Patent Nos. 1804801, 1763868, and 1891098, a more detailed description will be omitted.

2 to 6, the wire tightening device 100 according to the first embodiment of the present invention supports the rotational operation of the wire winding means 40 in which the wire w is wound or unwound therein. It includes a guide coupling part 10, a base body part 20 and a guider wing part 30 for the purpose.

Here, the guide coupling portion 10 is provided on one surface portion and the other surface portion spaced apart from the tightening object at a predetermined interval, and preferably includes a first support guide 11 .

In detail, the guide coupling part 10 is fitted to at least one pair of the shoelace via holes 1d formed in plurality along the edges of the skins 1a and 1b on both sides of the shoe 1 . That is, the guide coupling part 10 is coupled using the shoelace via hole 1d previously formed in footwear whose size is adjusted using a shoelace.

In addition, the base body 20 is provided under the wire winding means 40, and is disposed on the upper side of the tongue 1c provided between the skins 1a and 1b on both sides of the shoe 1 . Here, it is preferable that the lower surface of the base body part 20 is concavely rounded upward in consideration of the curvature of the instep.

At this time, the base body 20 may be integrally formed under the wire winding means 40 . Through this, the component parts of the wire tightening device 100 are minimized, so that the manufacturing cost and manufacturing man-hours can be reduced, thereby significantly improving production economy. In addition, when the wire winding means 40 is rotated in a state in which the base body 20 is fastened to the guide coupling part 10 through the guider wing part 30 to slide and guide the movement, the rotational force is the rotation. It may be substantially transmitted to the operation means and the reel unit.

Of course, in some cases, the base body part 20 and the wire winding means 40 are separately provided, but the lower end of the wire winding means 40 may be provided as a receptor to which is inserted and fixed. In this way, when the base body part 20 is provided separately from the wire winding means 40, the rotation operation means and the It is preferable that the rotation of the components except for the reel part is provided so as to be constrained.

That is, even if the wire winding means 40 is rotationally operated, it may further include a structure that restricts the rotation of the housing itself in which the rotation operation means and the reel part are accommodated inside the base body part 20 . For example, anti-rotation protrusions and anti-rotation grooves may be formed on opposite surfaces of the wire winding means 40 and the base body 20 to be coupled to each other, and key grooves into which the keys are inserted are formed on the opposite surfaces, respectively. may be

On the other hand, the guider wing portion 30 is provided with a second support guider 31 that protrudes to both sides of the base body portion 20 and is coupled to the first support guider 11 and slide guide movement.

Therefore, the present invention does not require a process of forming a separate incision or hole in the both sides of the skin (1a, 1b) or the tongue (1c) of the shoe (1) in order to install the wire tightening device (100). Through this, damage to the shoe (1) can be minimized and durability can be improved, and the guide coupling unit (10) does not require a high level of professional skill to install the wire tightening device (100). can be easily installed in the shoe (1).

In addition, unlike the prior art in which the wire tightening device 100 is fixed with sewing or adhesive, it is impossible to detach the guide coupling part 10 from the shoelace via hole 1d only by separating the wire tightening device 100 ) can be easily separated from the shoe (1). That is, the present invention is disclosed as a self-assembled (DIY) wire fastening device that can be installed and detachably attached to various shoes that the user already owns. Through this, while being provided with a size adjustment function such as an expensive shoe to which the wire tightening device is completely fixed in the prior art, the financial burden of the consumer is resolved and the desire to purchase can be increased, thereby securing market competitiveness.

Moreover, the wire winding means 40 is supported on both sides through the coupling of the guider wing part 30 and the guide coupling part 10 provided in pairs. Accordingly, when the wire winding means 40 is rotated, the wire winding means 40 and the base body part 20 are rotated by themselves to prevent distortion. That is, rotational force is transmitted through the rotational operation to the rotational operation means and the reel part, and the lower portion of the wire winding means 40 is restrained to support the rotational operation. Through this, since the rotational force of the rotation operation means is stably transmitted to the reel part, the distance at which the wire w is wound is precisely controlled, so that the wearing comfort can be significantly improved.

Here, it is preferable that the base body part 20 and the guider wing part 30 are provided integrally. In addition, it is preferable that the portion where the guider wing part 30 and the base body part 20 are connected is thicker than the extended outer end of the guider wing part 30 . Accordingly, rotation of the wire winding means 40 can be supported so that the rotational force is accurately transmitted to the reel unit through the rotation operation means when the wire winding means 40 is rotated.

In addition, it is preferable that the extended outer end of the guider wing portion 30 is formed in a thin band shape. Accordingly, it can be smoothly elastically deformed in response to the curvature of the instep and both sides of the foot. Through this, even when the guider wing part 30 is inserted into the inner skins 1a and 1b of the both sides of the shoe 1, excessive pressure on the user's foot or discomfort due to a foreign body can be minimized.

In addition, the wire winding means 40 is manufactured in a simple and economical structure in which the guide coupling part 10 and the guide coupling part 10 are fastened through the guide wing part 30 in a band shape. Therefore, the manufacturing man-hours and manufacturing costs of the product are reduced, and the product can be provided at an economical and affordable price to consumers, thereby securing market competitiveness through improved purchasing desire. Moreover, since the product is manufactured in a compact size, it can be applied to shoes of various designs and used without any discomfort.

On the other hand, one side of the first support guider 11 and the second support guider 31 extends to a predetermined length, but the slide movement may be limited only in the longitudinal direction through the slide guide structure formed on the other side. That is, the moving direction of the tightening object due to the tensile force of the wire and the sliding direction in which the first and second support guides 11 and 31 are fastened may be guided in opposite directions. Hereinafter, in the first embodiment, among the first support guider 11 and the second support guider 31, the second support guider 31 is one side and the first support guider 11 is the other side. and shown.

In detail, referring to FIG. 4 , the guider wing portion 30 is provided symmetrically in both directions of the base body portion 20 , and preferably extends to a predetermined length. Furthermore, the extended length of the guider wing portion 30 may be formed to be less than the vertical width of the both sides of the skin (1a, 1b). At this time, it is preferable that the second support guider 31 includes a guide long hole 32 cut to a predetermined length along the guider wing portion 30 . That is, in the first embodiment, the second support guider 31 is preferably understood as an extended portion of the guider wing portion 30 in which the guide long hole 32 is formed. This second support guide 31 is disposed on the inner surface of the both sides of the skin (1a, 1b) and slide guide movement between the instep and the both sides of the skin (1a, 1b) in a state in which the shoe 1 is worn on the foot. .

And, the guide coupling part 10 includes an extension part 10b disposed through the shoelace via hole 1d so as to penetrate the skins 1a and 1b on both sides of the shoe 1 in the thickness direction. This is preferable. In addition, the guide coupling portion 10 is preferably provided including a fixed end (10a) and an alignment end (10c) provided at one end and the other end of the extension portion (10b).

Here, the first support guide 11 includes a moving protrusion 13 extending from the fixed end 10a disposed on the outside of the both side skins 1a and 1b and passing through the guide long hole 32 . . And, it is provided at the end of the moving protrusion 13 and is caught by the rim of the guide long hole 32 includes a restraining portion 14 to prevent separation. In this case, the moving projection 13 is preferably understood as a part of the extension portion 10b, and the restraining portion 14 is preferably understood as substantially the same as the alignment end 10c.

Moreover, it is preferable that the extension portion 10b extends to a length exceeding the sum of the thicknesses of the both side skins 1a and 1b and the thickness of the second support guide 31 . And, the fixed end (10a) exceeds the inner diameter of the shoelace through hole (1d), the alignment end (10c) is preferably formed in an area exceeding the inner diameter of the short width of the guide long hole (32).

On the other hand, as in FIG. 5A , when the wire winding means 40 is operated to rotate in one direction and the wire w is wound, the length at which the wire w is exposed to the outside of the wire winding means 40 is reduced. And, the tensile force of the wire (w) is applied to the shoe (1). At this time, the tensile force of the wire w is transmitted to the wire winding means 40 as well as the both side skins 1a and 1b. Through this, the gap between the both sides of the skin (1a, 1b) and between the pair of guide coupling portion 10 and the wire winding means 40 is also narrowed.

Here, the guider wing part 30 protrudes from both sides of the base body part 20, and the second support guider 31, that is, the guider wing part 30, is of the both sides of the skin 1a, 1b. placed on the bottom At this time, the first support guide 11, that is, the guide coupling portion 10 is fixed to the shoelace via hole (1d), and movement is limited only at intervals corresponding to the inner diameter of the shoelace via hole (1d). can be And, the second support guider 31 is moved through the first support guider 11 to correspond to the inner diameter of the long guide hole 32 cut.

Therefore, when the wire winding means 40 is lowered, the guide long hole 32 is guided so that it slides only in the longitudinal direction by the moving protrusion 13, and the guider wing part 30 of the shoe (1). moved to the outsole side. At this time, the distance between the both skins 1a and 1b through which the wire w is passed in a zigzag is narrowed and the tongue 1c is in a state where the base body 20 is disposed on the upper side of the tongue 1c. ) to the instep side, a tensile force is applied. Through this, the shoe 1 can be adjusted to fit the size of the user's foot 2 .

Furthermore, the first support guide 11 and the second support guide 31 are provided between the shoe 1 and the user's foot 2 . At this time, when a portion of the wire w is wound during a one-way rotation operation of the wire winding means 40, the shoe 1 is tightened by a tensile force. In addition, the first support guide 11 and the second support guide 31 may be in close contact between the shoe 1 and the user's foot 2 and press-coupled by a tensile force.

Through this, even if each component is formed with a predetermined tolerance between each other so that the wire tightening device 100 can be smoothly manipulated, the flow can be constrained by the pressing force in the state in which the shoe 1 is tightened. Therefore, it is possible to prevent the shoe 1 from being loosened or changed due to the allowance tolerance through the wire winding means 40, so that the wearing comfort can be further improved.

On the other hand, when the rotation manipulation means and the reel part are operated to be separated, the reel part can be freely rotated, and the tensile force of the wire w is lost. At this time, when the user pulls the wire winding means 40 or the base body part 20 upward, the wire w is unwound from the reel part as shown in FIG. 5b and the both sides skins 1a, 1b and The tongue 1b may be spaced apart from the user's foot 2 .

At this time, as the restraining part 14 and the moving protrusion 13 are caught on the edge of the guide long hole 32, the guider wing part 30 is completely separated from the guide coupling part 10 and is separated. can be prevented. That is, if the guide coupling part 10 is not separated from the shoelace via hole 1d, the state in which the wire tightening device 100 is installed in the shoe 1 is always maintained. In addition, as the wire winding means 40 slides through the first support guide 11 and the second support guide 31 in a state disposed on the upper side of the tongue 1c, the inlet part into which the foot is put can be expanded.

Accordingly, since the shoe 1 can be tightened or loosened while repeatedly manipulating the wire winding means 40 , the wearing convenience can be significantly improved. Moreover, the wire (w) can be easily unwound by a simple operation of pulling the wire winding means 40 or the base body part 20 upward, so that the operation convenience can be remarkably improved.

At this time, referring to FIG. 6 , it is more preferable that the fixed end 10a is detachably provided from the extension portion 10b. In detail, a hook protrusion 12b may be formed at one end of the extension 10b, and a binding hole 12a to which the hook protrusion 12b is hook-coupled may be formed at the fixed end 10a. That is, the guide coupling part 10 sequentially passes the extension part 10b through the guide long hole 32 and the shoelace via hole 1d, and then the hook protrusion 12b in the binding hole 12a. ) is assembled by coupling the fixed end (10a) so that the hook is coupled. Through this, the guide coupling portion 10 can be easily coupled to the shoe 1 , and can be quickly separated from the shoe 1 by applying an external force.

Meanwhile, referring to FIGS. 2 to 6 , the guide coupling part 10 may be fitted in pairs to the plurality of shoelace via holes 1d, and between at least a pair of the guide coupling parts 10 . The wire winding means 40 is disposed. In addition, the wire (w) may be provided such that the portion exposed to the outside of the wire winding means 40 passes through the plurality of guide coupling portions 10 in a zigzag manner. To this end, the guide coupling portion 10 is preferably provided with a wire via portion 15 through which the wire (w) passes.

In detail, the wire via portion 15 is preferably provided at one end of the guide coupling portion 10, preferably at the fixed end 10a. In this case, the wire passage portion 15 may be formed as a groove or hole through which the wire w is inserted or caught. In addition, a round part for changing the passing direction of the wire (w) may be formed on one side of the inner surface of the wire via part 15 so that the wire (w) passes in a zigzag along the both sides of the skin (1a, 1b). .

In addition, the guide coupling part 10 is coupled to the plurality of shoelace via holes 1d and is provided symmetrically on the both sides of the skin 1a and 1b, and the wire w is each of the guide coupling parts 10 ) may be disposed to pass through the wire via portion 15 formed in the whole. That is, when the wire (w) is coupled to the guide coupling part 10 to the shoelace via hole (1d) in a state in which the wire is passed through the wire via part 15, the wire tightening device 100 can be variously used. It can be used interchangeably with shoes (1). In addition, when the guide coupling part 10 is separated, the wire tightening device 100 can be separated as a whole. Therefore, since the shoelace or the wire tightening device 100 can be replaced and applied to a single shoe 1 as needed and worn in various styles, usability and aesthetic satisfaction can be significantly improved.

At this time, the wire (w) may be provided to pass through the guide coupling part 10 other than the guide coupling part 10 fastened to the guider wing part 30, but the guider wing part 30 and It is preferable to first pass through the pair of fastened guide coupling portions 10 . Through this, since the rotational force of the wire (w) winding device is applied corresponding to the extension direction of the guider wing part 30, the base body part 20 including the wire winding means 40 is the shoe (1) ) can be prevented from leaning toward the anterior nose.

Alternatively, the guide coupling part 10 is coupled to a pair of shoelace via holes 1d corresponding to the guider wing part 30, and the wire w is provided to pass through the remaining shoelace via holes 1d. could be That is, if the distance between the both side skins 1a and 1b can be adjusted while the wire w is wound by the rotational force of the wire winding means 40, the wire w can be wound in various ways. and such modifications are within the scope of the present invention.

On the other hand, the guider wing portion 30 is extended to a predetermined length, it is preferable to extend symmetrically in both directions from the base body portion 30 to each other. At this time, the angle between the guider wing portions 30 made of a pair may be formed as an obtuse angle, but preferably may be formed as 180°. Through this, the base body portion 20 including the wire winding means 40 can be supported in a balanced way from left and right sides, so that the position of the wire winding means 40 can be more stably supported during the rotation operation.

In addition, the guider wing portion 30 may protrude as a pair as shown in the figure, but may be branched into a plurality and formed symmetrically, and may be formed in a stick shape or a fan shape extending toward the end.

On the other hand, Figure 7 is a cross-sectional view showing the fastening state of the first support guider and the second support guider in the wire tightening device according to the second embodiment of the present invention, Figure 8 is a wire according to the third embodiment of the present invention It is an exemplary cross-sectional view showing the fastening state of the first support guider and the second support guider in the tightening device. In the second and third embodiments, except for the fastening structure of the first support guider and the second support guider, the basic configuration is the same as that of the first embodiment, so a detailed description of the same configuration will be omitted. In each of the following embodiments, the first support guiders 211 and 311 are provided in the guide coupling portion, and the second support guiders 231 and 331 are provided in the guider wing portion as an example.

As shown in FIG. 7 , one side of the first support guide 211 and the second support guide 231 extends to a predetermined length and includes a rail portion 233 in which a locking groove 233a is formed along the longitudinal direction. may be included. In addition, the other side may be provided to include a locking projection 214a extending from the fixed end (210a), the end of which is caught by the rail portion (233).

In addition, the other side may be provided with a guide hole 314a extending from the fixed end 310a and penetrating in the lateral direction so that the through extension part 334 passes therethrough.

That is, the second support guider ( 231,331) may be limited in its extended longitudinal direction.

Moreover, if one side of the first support guider and the second support guider extends in the longitudinal direction and the other side supports the one side to slide only in the longitudinal direction, it can be applied in various ways other than the above-described examples. In addition, in each embodiment of the present invention, one side extending in the longitudinal direction is provided in the guider wing portion and the other side is provided in the guide coupling portion as an example, but the opposite embodiment is also possible. That is, the guider wing portion may include a configuration for the first support guider and the guide coupling portion may include a configuration for the second support guider, and such a modified implementation falls within the scope of the present invention.

Meanwhile, FIGS. 9A and 9B are exemplary views showing modifications of the guide coupling unit applied to each embodiment of the present invention. In this modified example, since the basic configuration except for the guide coupling part is the same as in each of the above-described embodiments, a detailed description of the same configuration will be omitted.

As shown in FIG. 9A , the fixing end 410a may be detachably provided from the extension portion 410b, and may be coupled by screwing each other through screws 416a and 416b formed on opposite fastening surfaces. Alternatively, as shown in FIG. 9B , the fixed end 510a is integrally formed with the extension 510b, and the alignment end 510c has a thickness that can be elastically deformed by an external force from the other end of the extension 510b. may be formed as That is, in each of the above-described embodiments, the extension of components such as the extension part or the locking protrusion from each of the fixed ends means that they are integrally protruded from the fixed end and that they are connected to one end of the fixed end and extend. It is preferable to understand that it encompasses what is provided in the shape.

In this way, the guide coupling parts 410 and 510 may be provided in various shapes that can be easily separated from the shoe by applying an external force over a predetermined force while preventing separation from the shoe in a state coupled to the shoelace via hole. can At this time, the predetermined force is preferably understood as a force greater than the rotational force applied to the wire winding means. Accordingly, the wire tightening device may be stably coupled without being separated from the shoe by a rotational force generated by rotating the wire winding means and a tensile force applied to the wire through this.

In this case, terms such as "include", "comprise", "include" or "have" described above mean that the corresponding component may be inherent, unless otherwise stated. It should be construed as not excluding components, but may further include other components. All terms, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs, unless otherwise defined. Terms commonly used, such as those defined in the dictionary, should be interpreted as being consistent with the contextual meaning of the related art, and are not interpreted in an ideal or excessively formal meaning unless explicitly defined in the present invention.

As described above, the present invention is not limited to each of the above-described embodiments, and modifications can be implemented by those of ordinary skill in the art to which the present invention pertains without departing from the scope of the claims of the present invention. and such modifications are within the scope of the present invention.
