  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out the embodiments. However, the present invention can be implemented in various other forms and is not limited to the embodiments described herein. In the drawings, parts unnecessary for the description are omitted in order to clearly describe the present invention, and the same reference numerals are given to the same or similar components throughout the specification.

  In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes on an orthogonal coordinate system, and can be interpreted in a broad sense including this. For example, the x axis, the y axis, and the z axis may be orthogonal to each other, but may also refer to different directions that are not orthogonal to each other.

  On the other hand, when various components such as layers, membranes, regions, plates, etc. are “on” other components, this is not only when they are “above” other components, but also other components in between. This includes the case where

  FIG. 1 is a perspective view for explaining a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, showing a string winding device. .

  The string winding device of the present invention includes a base unit 100, a middle unit 200 coupled to the base unit, a rotating unit 300 positioned in the base unit 100 or the middle unit 200 so as to be rotatable with respect to the base unit 100, and the middle unit 200. The cover unit 400 may be rotatably coupled to the cover unit 400.

  The base unit 100 includes a base plate 110 having a plate shape such as a disc and a lower housing 120 having a cylinder shape. Of course, the shape of the base plate 110 is not limited to a circular plate, and may have various plate shapes. The cylinder shape here can be understood to be similar to a hollow cylinder. Such a lower housing 120 may be disposed on the upper surface (+ z direction) of the base plate 110. The base plate 110 and the lower housing 120 may be integrally formed from a resin or the like.

  The lower housing 120 has a second side surface through hole 122. Of course, the lower housing 120 may have a first side surface through hole 121 as shown in FIG. In this case, the first side surface through hole 121 may be disposed closer to the base plate 110 than the second side surface through hole 122. The lower housing 120 is shown as having two first side surface through holes 121 and two second side surface through holes 122 so as to be substantially opposed to each other, but this is merely an example. The first side surface through hole 121 and the second side surface through hole 122 can function as long as there is at least one or more. In FIG. 2, the first side surface through-hole 121 is located on a straight line in the y-axis direction, and the second side surface through-hole 122 is also located on a straight line in the y-axis direction. You may align on a substantially straight line. On the other hand, in FIG. 2, the first side surface through hole 121 and the second side surface through hole 122 are shown as being vertically parallel, but the first embodiment of the present invention is not limited to this. For example, as shown in FIG. 2, the first side surface through-hole 121 may be positioned on a straight line in the y-axis direction, and the second side surface through-hole 122 may be disposed on a straight line in the x-axis direction. Good.

  A plurality of through holes 111 having a central axis in the z-axis direction may be formed in an outer portion of the lower housing 120 of the base plate 110 of the base unit 100. When the string winding device according to the first embodiment of the present invention is attached to footwear or the like, the through hole 111 can pass a fastener that fixes the base plate 110 to the footwear or the like.

  On the other hand, as shown in FIG. 2, the base unit 100 may further include a rotation support portion 130 that protrudes toward the center of the lower housing 120 on the inner surface of the lower housing 120. A rotation support protrusion 132 protruding upward (+ z direction) may be formed on the upper surface of the rotation support part 130. The rotation support portion 130 and the rotation support protrusion 132 can support the rotation unit 300 so that the rotation is smooth when the rotation unit 300 rotates with respect to the base unit 100.

  The middle unit 200 has a cylinder-shaped upper housing 210. A cylinder-shaped upper housing 210, which can be understood as a shape similar to a hollow cylinder, can be coupled to the lower housing 120 of the base unit 100.

  Such a middle unit 200 may also include a partition wall 240 as required.

  A first reverse rotation prevention unit 250 may be disposed on one side of the upper housing 210 in the −y direction or the rotation center direction of the string winding device.

  The first reverse rotation prevention unit 250 may be formed of a continuous protrusion formed in a sawtooth shape, and may have a structure in which one side surface of the protrusion is formed as an inclined surface and can rotate only in one direction.

  The upper housing 210, the partition wall 240, and the first reverse rotation prevention unit 250 may be integrally formed from a resin or the like.

  The rotation unit 300 may be disposed inside the lower housing 120 of the base unit 100 and may be rotatably arranged with respect to the base unit 100. Here, the rotation unit 300 being located inside the lower housing 120 means that at least a part of the rotation unit 300 is located inside the lower housing 120, and a part of the rotation unit 300 is located above the lower housing 120. The upper housing 210 may be disposed in various forms such as a variety of forms.

  The rotation unit 300 has a first engagement portion 310 on the upper surface in the + z direction. Although the first meshing portion 310 is shown as having a concave groove shape, it is needless to say that the first meshing portion 310 may have a convex shape. When such a first meshing part 310 meshes with a second meshing part 450 of the cover unit 400 described later, the rotating unit 300 can rotate together with the cover unit 400. At this time, in order to prevent the rotating unit 300 and the cover unit 400 from idling with respect to each other even though the first engaging portion 310 and the second engaging portion 450 are engaged with each other, the first engaging portion 310 and the first engaging portion 310 The shape of the two meshing portions 450 (xy plane reference) may have various shapes such as a polygon, an ellipse, or an asymmetrically distorted circle. In addition, the shape of the first meshing portion 310 and the second meshing portion 450 in the xy plane is a structure in which at least one pin and a pin hole correspond to each other, and the rotation unit 300 and the cover unit are configured by fitting and coupling the pin and the pin hole. 400 can be coupled together.

  The rotation unit 300 can include a first wing portion 321 and a second wing portion 322. The first wing portion 321 and the second wing portion 322 maintain a certain distance from each other, and a space around which the string is wound may be provided between them.

  A string can be wound around the space between the first wing portion 321 and the second wing portion 322 by the rotation of the rotation unit 300. That is, the first wing portion 321 and the second wing portion 322 form a space in which the wound string is positioned when the string is wound according to the rotation direction of the rotary unit 300.

  On the other hand, the rotary unit 300 is positioned at the lower part (in the −z direction) so as to be closer to the base plate 110 than the second wing part 322 as necessary, and is similar to the second wing part 322 and protrudes in the radial direction. A wing 323 can be further included. Further, the bottom surface of the third wing portion 323 is flat, and a part of the bottom surface of the third wing portion 323 is in contact with or adjacent to the upper surface (+ z direction) of the base plate 110 of the base unit 100. Can be arranged in Therefore, the rotation unit 300 can stably rotate with respect to the base plate 110.

  The rotating unit 300 may have a first through hole 331 that is located below (−z direction) the second wing portion 322 and penetrates the rotating unit 300. The first through hole 331 can correspond to the first side surface through hole 121 of the base unit 100. Here, the fact that the first through hole 331 corresponds to the first side surface through hole 121 means that the height of the first through hole 331 from the base plate 110 is substantially the same as the height of the first side surface through hole 121 from the base plate 110. It means that.

  The rotation unit 300 may have a second through hole 332 that penetrates the rotation unit 300 in a space between the first wing portion 321 and the second wing portion 322. The second through hole 332 can correspond to the second side surface through hole 122 of the base unit 100. Here, the fact that the second through hole 332 corresponds to the second side surface through hole 122 means that the height of the second through hole 332 from the base plate 110 and the height of the second side surface through hole 122 from the base plate 110 are substantially the same. It means that.

  A string (not shown) provided for footwear or correction underwear passes through any one of the plurality of second side surface through holes 122 of the base unit 100 and passes through the second through hole 332 of the rotating unit 300. Then, it can pass through the other one of the second side surface through holes 122. As another example of the first embodiment of the present invention, the string may be fixed inside the base unit 110 after passing through the second through hole 332 of the rotating unit 300. Accordingly, when the rotation unit 300 is engaged with the cover unit 400 and rotates in one direction, the string is wound around the rotation unit 300. Specifically, the string is wound up in a space provided between the first wing portion 321 and the second wing portion 322 of the rotating unit 300. As a result, a string such as footwear or correction underwear can be wound around the rotary unit 300. At this time, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 provided to the cover unit 400 and the middle unit 200 may be coupled to each other. The first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 can rotate in one direction, and when the rotation stops, they are fixed to each other at that position. That is, the second reverse rotation prevention unit 460 includes a protruding part that partially protrudes, and may be configured to rotate in one direction with respect to the first reverse rotation prevention unit 250.

  Of course, when the rotary unit 300 is separated from the cover unit 400 in such a state, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 may be separated from each other to release the winding state. At this time, the rotating unit 300 can be rotated in both directions, whereby the string wound around the rotating unit 300 can be unwound from the outer peripheral surface of the rotating unit 300.

  Of course, the present invention is not limited to this, and the rotating unit 300 may not have the second through hole 332. In this case, one end of a string such as footwear or correction underwear passes through one of the plurality of second side surface through holes 122 of the base unit 100 and is fixed to the rotating unit 300, and the other end of the string such as footwear. May pass through another one of the plurality of second side surface through holes 122 of the base unit 100 and be fixed to the rotating unit 300. In this case, for fixing the one end and the other end of the string, the rotating unit 300 may have at least one fixing protrusion for fixing the string.

  The rotating unit 300 can rotate relative to the base unit 100 when rotating, and it is preferable to increase the rotational safety of the rotating unit 300. Therefore, the rotation support part 130 and the rotation support protrusion 132 of the base unit 100 can interact with the second wing part 322 of the rotation unit 300. For example, the rotation unit 300 has a rotation protrusion 322 a protruding downward (−z direction) at the radial end of the second wing 322, and of the surfaces below (−z direction) of the second wing 322. When the rotation unit 300 rotates by making the portion adjacent to the rotation protrusion 322a adjacent to or in contact with the rotation support protrusion 132 of the base unit 100, the rotation center of the rotation unit 300 is rotated. The position of the shaft can be fixed without moving relative to the base unit 100.

  Such a rotation unit 300 may be formed of a synthetic resin material or a metal material.

  The cover unit 400 may be coupled to the middle unit 200 so as to be rotatable with respect to the middle unit 200. Of course, when the cover unit 400 is engaged with the rotary unit 300 as described above, the cover unit 400 can rotate in one direction together with the rotary unit 300.

  Such a cover unit 400 has a corresponding locking portion 410 protruding in the radial direction. The corresponding locking part 410 may be fitted between the upper locking part 270a and the lower locking part 270b provided to the middle unit 200, or may be disposed outside (upper side) of the upper locking part 270a. As described above, the distance between the cover unit 400 and the base unit 100 is variable, and the cover unit 400 can be engaged with the rotary unit 300 or separated from the rotary unit 300.

  Specifically, the corresponding locking portion 410 is positioned in the first space between the upper locking portion 270a and the lower locking portion 270b, or the second space outside the upper locking portion 270a (the upper side in FIG. 2). The position of the cover unit 400 from the base unit 100 can be varied by moving the cover unit 400 to the position shown in FIG. When the corresponding locking portion 410 is located in the first space, the cover unit 400 can mesh with the rotary unit 300 and rotate in one direction together with the rotary unit 300, and when the corresponding locking portion 410 is located in the second space, the cover unit When the 400 is separated from the rotation unit 300, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 are separated from each other. Accordingly, the rotation unit 300 can rotate in one direction or the other direction, regardless of the movement of the cover unit 400.

  The cover unit 400 has a second engagement portion 450 in the −z direction of the intermediate portion. Although the second meshing portion 450 is illustrated as having a convex protruding shape, it may be deformed into a corresponding shape depending on the shape of the first meshing portion 310 of the rotating unit 300 such as a concave groove shape. When the second meshing part 450 is meshed with the first meshing part 310 of the rotary unit 300 described above, the rotary unit 300 can rotate together with the cover unit 400. At this time, in order to prevent the rotating unit 300 and the cover unit 400 from idling with respect to each other even though the first engaging portion 310 and the second engaging portion 450 are engaged with each other, the first engaging portion 310 and the first engaging portion 310 The cross-sectional shape of the two meshing portions 450 in the xy plane has various shapes such as a polygon, an ellipse, or an asymmetrically distorted circle, and may have a configuration of a pin and a pin hole.

  On the other hand, the cover unit 400 has a central axis 430. The corresponding locking portion 410 may be formed in a flange shape extending radially from the central shaft 430. The cover plate 420 may be disposed on the upper portion of the central axis 430 in the + z direction.

  The side plate 440, which can be understood as a portion where the peripheral edge of the cover plate 420 is bent by approximately 90 degrees, is formed when the cover unit 400 is coupled to the middle unit 200, as shown in FIG. Can cover at least a portion of. FIG. 2 shows that the side plate 440 covers most of the outer peripheral surface of the upper housing 210 of the middle unit 200.

  Various components of the cover unit 400 can be integrally formed from a synthetic resin material or a metal material. Of course, some components of the cover unit 400 may be coupled to the central shaft 430 as separate components separated from the central shaft 430. In this case, such partial components are It can be formed from a synthetic resin material or a metal material.

  In the case of the string winding device according to the first embodiment of the present invention, when the corresponding locking portion 410 is located in the first space between the upper locking portion 270a and the lower locking portion 270b, the cover unit 400 is The rotating unit 300 can mesh with the rotating unit 300 and rotate in one direction, so that the string is wound on the outer peripheral surface of the rotating unit 300.

  When the corresponding locking portion 410 is positioned in the second space above the upper locking portion 270a (see FIG. 5), the cover unit 400 moves away from the rotation unit 300, so that the rotation unit 300 moves the cover unit 400. Regardless of the direction, it can rotate in the other direction opposite to the one direction, that is, in the unwinding direction. Therefore, the string wound around the outer peripheral surface of the rotary unit 300 is unwound. That is, the string is wound or unwound according to the relative position between the corresponding locking portion 410 of the cover unit 400 and the middle unit 200.

  In the case of the string winding device according to the first embodiment of the present invention, when the upper locking portion 270a or the lower locking portion 270b of the middle unit 200 is damaged, the base unit 100, the rotation unit 300, and the cover unit 400 are It is possible to replace only the middle unit 200 as it is. Such a first embodiment of the present invention has an advantage that maintenance and repair can be performed quickly and easily. Furthermore, in the case of the winding device according to the first embodiment of the present invention, no special expertise or the use of a specific tool is required for maintenance and repair, and the screw-fitted parts are simply replaced or replaced. Since it can be maintained and repaired by inserting parts, it has the advantage that the user can easily use it directly.

Hereinafter, the first embodiment of the string winding device of the present invention will be described in more detail.
According to the first embodiment of the present invention shown in FIGS. 1 to 5 (first embodiment having a two-stage configuration), the entire apparatus has a two-stage configuration, and the height thereof can be reduced.

The first meshing part 310 and the second meshing part 450 between the units 300 are all included in the first stage (I). And the 1st wing | blade part 321 and the 2nd wing | blade part 322 of the rotation unit 300 which can wind up a string are contained in 2nd step (II). As a result, the overall height (or thickness) of the string winding device shown in FIG. 2 is relatively lower than that of the existing one. In this way, the string take-up device with a reduced height can be used not only for a lace fastener of an athletic shoe but also for a lace fastener such as a correction underwear. In particular, when the embodiment of the present invention is applied to the corrected undergarment, it is possible to improve the feeling of wearing and to improve the dressing of clothes by minimizing what protrudes to the outside.

  Hereinafter, each configuration will be described in more detail. First, in the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460, the first reverse rotation prevention unit 250 of the middle unit 200 is formed on the upper housing 210 extending upward from the partition wall 240. In the first embodiment of the present invention, the first reverse rotation preventing part 250 is located on the upper housing 210 and exists in the first stage (I) in the same area as the locking part 270 and the corresponding locking part 410.

  Corresponding locking portion 410 has a disk or flange configuration extending radially from central axis 430. Then, the corresponding locking portion 410 interacts with the locking portion 270 of the middle unit 200 so that the cover unit 400 can move relative to the middle unit 200 in the + z or −z direction.

  The locking part 270 of the middle unit 200 can be configured by a wire spring formed by a wire, an elastic flexure, or the like. That is, the upper locking portion 270a and the lower locking portion 270b constituting the locking portion 270 can use wire springs or elastic flexures formed with wires.

  FIG. 3 is a partial cross-sectional view taken along the line AA ′ of FIG. 2 and viewed from the plane side. The upper locking portion 270 a of the locking portion 270 is coupled to the mounting protrusion 260 of the middle unit 200. It shows the state. That is, the upper locking portions 270a of the locking portions 270 are installed on the mounting protrusions 260 separately formed on the inner side of the middle unit 200 and fixed in two rows with a predetermined interval when viewed on the xy plane. obtain. In the embodiment of the present invention, the lower locking portion 270b of the locking portion 270 is not shown in the drawing, but the lower portion of the upper locking portion 270a has a shape similar to that of the upper locking portion 270a. Can be combined.

  4 is a view showing another example of the state in which the upper locking portion 270a of the locking portion 270 of FIG. 3 is coupled to the mounting protrusion 260 of the middle unit 200. The portion 270a may be installed on the mounting protrusion 260 of the middle unit 200 while forming a substantially triangular shape. The example illustrated in FIG. 4 shows that the installation form of the upper locking portion 270a of the locking portion 270 of FIG. 3 can be varied.

  Further, as another example in which the locking portion 270 including the upper locking portion 270 a and the lower locking portion 270 b is coupled to the mounting protrusion 260 of the middle unit 200, the locking portion 270 is installed only on one side of the mounting protrusion 260. It may be installed in various forms such as a polygon, a curved line, or a bent curve when seen in a plan view. As described above, if the elastic locking portion 270 formed of a wire spring or an elastic flexure is used, the locking and releasing action is performed more smoothly and the durability is improved.

  Further, as another example of the present invention, the engaging portion 270 may be formed of a protrusion protruding from the side surface of the middle unit 200 to the center portion instead of being formed from a wire spring or an elastic flexure. . Such an example has an advantage that, when the middle unit 200 is molded, the projecting portion serving as the locking portion 270 can be molded at the same time, so that the number of parts can be reduced and the production cost can be reduced.

  As described above, the locking portion 270 is arranged such that the upper locking portion 270a and the elastic lower locking portion 270b are separated in the + z direction.

  The corresponding locking portion 410 may be disposed between the upper locking portion 270a and the lower locking portion 270b (see FIG. 2), and is disposed on the outer side (upper side) of the upper locking portion 270a (see FIG. 5).

The meshing portions 450 mesh with each other. At the same time, the first reverse rotation prevention unit 250 of the middle unit 200 and the second reverse rotation prevention unit 460 of the cover unit 400 are also coupled to each other.

  As a result, when the user rotates the cover unit 400, the string is wound while meshing with the cover unit 400 and rotating the rotary unit 300. At this time, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 prevent the cover unit 400 from rotating in the opposite direction, and the string wound around the rotation unit 300 by a certain length is not loosened again. .

  Next, as shown in FIG. 5, the user pulls the cover unit 400 upward (in the + z direction) to place the corresponding locking portion 410 on the upper side of the upper locking portion 270a. Then, the state where the first engagement portion 310 and the second engagement portion 450 are coupled to each other is released, and the state where the first reverse rotation prevention portion 250 and the second reverse rotation prevention portion 460 are also coupled to each other is released. .

  Then, the jaw 280 can be formed on the upper end of the mounting protrusion 260 of the middle unit 200 to prevent the corresponding locking portion 410 from being completely detached from the upper locking portion 270a. As described above, when the coupled state of the cover unit 400 and the rotating unit 300 is released, the string wound around the rotating unit 300 can be naturally unwound by its own restoring force.

  Hereinafter, a second embodiment of the present invention (second embodiment having a two-stage configuration) shown in FIGS. 7 and 8 will be described. In the description of the second embodiment of the present invention, the same portions as those in the above-described example are replaced by the descriptions, and only different points will be described.

  The second embodiment of the present invention includes a locking portion 270 and a corresponding locking portion 410 disposed between the cover unit 400 and the middle unit 200, a first reverse rotation prevention portion 250 and a second reverse rotation prevention portion 460, and A first meshing portion 310 and a second meshing portion 450 between the cover unit 400 and the rotating unit 300 are included in the first stage (I).

  And the 1st wing | blade part 321 and the 2nd wing | blade part 322 which wind up the string of the rotation unit 300 are contained in 2nd step (II). Such a second embodiment of the present invention can serve to reduce the overall height of the string winding device.

  Hereinafter, each configuration will be described in more detail. The first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 are disposed to face each other along the z direction.

  That is, the first reverse rotation prevention unit 250 of the middle unit 200 is formed on the partition wall 240 in the + z direction. The second reverse rotation prevention unit 460 of the middle unit 200 is formed at a position corresponding to the first reverse rotation prevention unit 250. As a result, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 formed on the partition wall 240 are in the first stage (I) in the same area as the locking portion 270 and the corresponding locking portion 410. Be placed.

  In addition, the locking portion 270 and the corresponding locking portion 410 are formed on the side surfaces with separate protrusions protruding from the cover unit 400 toward the base unit 100. The corresponding locking part 410 and the locking part 270 provided on the upper housing 210 of the middle unit 200 interact with each other so that the cover unit 400 can be moved relative to the middle unit 200. The locking part 270 of the middle unit 200 is formed of a wire-formed wire spring, an elastic flexure, or the like, and may be fixedly installed so as to have two rows or a triangular shape when viewed on the xy plane.

  In addition, the locking portion 270 may be arranged such that the upper locking portion 270a and the lower locking portion 270b are separated in the + z direction. Depending on the relative position of the corresponding locking portion 410 between the upper locking portion 270a and the lower locking portion 270b, the distance of the cover unit 400 from the base unit 100 can be changed, and the meshing with the rotating unit 300 can be released. .

  That is, as shown in FIG. 7, when the corresponding locking portion 410 is positioned below the lower locking portion 270b, the first meshing portion 310 and the second meshing portion 450 mesh with each other and simultaneously prevent the first reverse rotation. The part 250 and the second reverse rotation prevention part 460 are also coupled to each other. As a result, when the user rotates the cover unit 400, the string is wound while the rotating unit 300 is rotated. At this time, the first reverse rotation prevention unit 250 and the second reverse rotation prevention unit 460 prevent the cover unit 400 from rotating in the opposite direction. Therefore, the string wound between the first wing portion 321 and the second wing portion 322 of the rotating unit 300 does not loosen again.

  Next, as shown in FIG. 8, the user pulls the cover unit 400 upward to place the corresponding locking portion 410 between the upper locking portion 270a and the lower locking portion 270b. Then, the first meshing part 310 and the second meshing part 450 are separated from each other, and the first reverse rotation prevention part 250 and the second reverse rotation prevention part 460 are also disconnected from each other. As described above, when the coupling between the cover unit 400 and the rotating unit 300 is released, the string wound around the rotating unit 300 is naturally unwound by its own restoring force.

  The third embodiment of the present invention shown in FIGS. 9 and 10 (third embodiment having a two-stage configuration) will be described below. In the description of the third embodiment of the present invention, the same portions as those in the above-described example are replaced by the descriptions, and only different points will be described.

  The third embodiment of the present invention includes a locking part 270 and a corresponding locking part 410 between the cover unit 400 and the middle unit 200, a first reverse rotation prevention part 250 and a second reverse rotation prevention part 460, and the cover unit 400. The configuration of the first meshing part 310 and the second meshing part 450 between the rotary unit 300 and the rotary unit 300 is included in the first stage (I).

  And the 1st wing | blade part 321 and the 2nd wing | blade part 322 which wind up the string of the rotation unit 300 are contained in 2nd step (II). As a result, the overall height of the string winding device can be reduced.

  When compared with the previous embodiment, the third embodiment of the present invention has the following differences. The locking part 270 is provided on the cover unit 400. The corresponding locking portion 410 is provided to the middle unit 200. Further, in the above-described embodiment, the locking portions 270 are arranged in pairs in the vertical direction, but in the third embodiment of the present invention, one locking portion 270 is provided.
