Description

Apparatus for controlling string < RTI ID = 0.0 >

More particularly, the present invention relates to a strap adjusting device, and more particularly, to a strap used for various wearing products or household goods, including shoes, bags, clothes, etc., And a tension adjusting device for adjusting a characteristic of a strap including a tension applied to a position or a strap.

In general, a string is a string whose meaning is characterized by a large difference in thickness or width in length, and can be applied to all kinds of objects having a characteristic of bending down, string, wire, rope, band, and the like.

In general, various types of wearable products, including shoes, bags, backpacks, garments, etc., are provided with means for tightening / unscrewing using strings or the like, for example, wires or bands . Also, for example, when handling heavy machinery, ropes of various materials are used. For example, in the case of a shoe, the strap is mounted so as to be connected in a zigzag fashion, and by tightening such a strap, the shoe can be brought into close contact with the user's foot.

However, since it is very troublesome to loosen or tighten the straps every time you take off your shoes, it is common to wear shoes without tightening the straps so that the shoes do not come into close contact with your feet. In this case, when the shoes are brought into close contact with the user's feet for exercise or the like, the string is pulled again, and then loosened again to loosen the string, which inconveniences the user. In addition, there is a disadvantage that when the strap is loosened during walking or during exercise, the strap must be tied again.

Hereinafter, a method of operating the string adjusting apparatus 100 according to the first embodiment of the present invention will be described in detail with reference to an example of the string adjusting apparatus 100 disclosed in Figs.

The user first hooks the string on the string hook 165 formed on the bobbin 160 of the rotary unit 150. [ In this state, the rotation unit 150 and the base unit 110 are coupled so that the rotation base 170 of the rotation unit 150 is inserted into the lower housing 113 of the base unit 110. At this time, the string is aligned and inserted so as to pass through the string insertion portion 113d of the base unit 110. [ Alternatively, the cord insertion portion 165 of the bobbin 160 and the cord insertion portion 113d are firstly inserted in an aligned manner, and then the cord is pushed out of the base unit 110 to the cord insertion portion 113d It can also be mounted.

In this process, the first locking protrusion 155a of the locking member 155 is brought into contact with the locking protrusion 113a of the lower housing 113. At this time, the user overcomes the elastic force of the locking member 155, The unit 150 is pushed in and the engaging member 155 is elastically deformed so that the first engaging protrusion 155a passes over the engaging protrusion 113a. At this time, the surface of the first locking protrusion 155a where the first locking protrusion 155a meets the locking protrusion 113a is inclined, so that the locking protrusion 113a can easily pass over.

In this state, the latching jaws 113a are positioned between the first and second latching protrusions 155a and 155b.

When the force is applied to separate the rotary unit 150 and the base unit 110 from each other in the coupled state, the surface of the first locking protrusion 155a, which contacts the lower end of the locking protrusion 113a, And is controlled so as not to be separated from the base unit 110 because the rotation unit 150 is formed to be hung horizontally on the base unit 113a.

In the coupled state, the rotary unit 150 is rotatable in both the winding direction and the loosening direction.

When the user further inserts the rotation unit 150 in the direction of the base plate 111 again in the coupled state, the engaging protrusion 113a rides over the second engaging protrusion 155b, The engaging step 113a is engaged with the inclined portion 155c. More specifically, the latching surface 113c of the latching jaw 113a is engaged with the second latching protrusion 155b to be in a fully engaged state. In this case, the rotation unit 150 can rotate only in one direction, that is, in a winding direction.

When the user holds the rotary head 151 and rotates the string in the winding direction of the string, the rotation of the rotary unit 150 is stopped by the engagement protrusion 155c facing the inclined part 155c of the second locking protrusion 155b, The engaging member 155 is elastically deformed in the direction of the engaging slit 159 as the inclined surface 153b of the engaging member 113a comes into contact with each other and the inclined portion 155c moves on the inclined surface 113b.

When the inclined portion 155c is out of the inclined surface 113b, the engaging surface 113c of the engaging protrusion 113a is hooked on the other side (not shown) of the inclined portion 155c, The rotation of the rotation unit 150 in the opposite direction is limited and the position is fixed.

When the rotary unit 150 continuously rotates in the direction of winding the string in the fully engaged state, the above-described operation is repeated so that the string is gradually wound on the bobbin 160, Is adjusted.

The rotating unit 150 must be able to rotate freely about the base unit 110, in the direction opposite to the winding direction of the strap, in order to release the strap without detecting it. This state is defined as a coupling state. This is because when the user holds the rotary head 151 of the string adjusting device 100 in a fully engaged state and pulls the rotary head 151 in a direction away from the base plate 111, do. The operation principle is such that the engaging surface 113c of the engaging protrusion 113a and one side surface of the inclined portion 155c of the engaging member 155 meet with each other to transmit force to each other and to resist movement, And the resistance disappears. In the fully engaged state, the latching jaws 113a are supported and engaged by the second latching protrusions 155b. In the coupled state, the latching jaws 113a ride over the second latching protrusions 155b, And is placed between the first protrusion 155a and the second protrusion 155b. At this time, the latching jaw 113a is held by the first latching protrusion 155a.

Referring to FIG. 21, the positions of the latching jaws 113a and the latching members 155 can be mutually changed. That is, it is also possible that the latching protrusion 113a is formed in the rotation unit 150 and the latching member 155 is formed in the lower housing 113. It will be apparent to those skilled in the art that there is no effect on the principle of operation even when the mutual position is changed (see Fig. 21 (a)).

21 (c)), the engaging protrusion 113a is formed in the lower housing 113, and the engaging member 155 is formed on the bobbin (See Fig. 21 (b)) formed along the periphery of the bobbin, and the engaging member 155 is formed in the lower housing 113. [ In this case, the locking protrusion 113a and the locking member 155 are located inside the lower housing 113, and the radius of the lower housing 113 should be relatively large.

The position where the engaging protrusion 113a and the engaging member 155 are in contact with each other is the upper end of the lower housing 113. However, It is possible to set variously according to need.

Fig.

According to the string adjusting apparatus 200 of the second embodiment of the present invention, a lower housing 213 having a cylindrical shape including a base plate 211 and opened in at least one direction, A base unit 210 including an engaging member 220 elastically deformable at one end thereof; At least a part of which is rotatably installed in the lower housing 213 and has a bobbin 260 on which a string is wound on the outer surface, a rotary head 251 having the bobbin 260 installed substantially at the center, (253) formed on one surface of the rotating shaft (251) to be opposed to the engaging member (220) along a copper line where the engaging member (220) 250).

The string adjusting apparatus 200 according to the second embodiment is configured such that the latching member 220 is formed on the lower housing 213 and the latching jaw 253 is installed on one side of the rotation unit 250 . Although not shown, it is also possible that the latching jaw 253 is formed in the lower housing 213 and the latching member 220 is formed in the rotary head 251 as in the first embodiment.

The base plate 211 may be formed as a single plate or may be formed to protrude along the outer surface of the lower housing 213 rather than one plate.

The engaging member 220 includes a fixed end 223 connected to the lower housing 213, a free end 221 extending from the fixed end 223 and elastically deformable, The free end 221 of the engaging member 220 and the lower end of the lower housing 213 are elastically deformed to elastically deform the engaging member 220. [ A part of the slit 227 can be cut to form the latching slit 227. [ In the drawing, an end portion of the engaging member 220 toward the rotary head 251 of the lower housing 213 is shown as an example of the one portion.

The free end 221 is elastically deformable in the direction of the rotary head 251 with respect to the fixed end 223, and the engaging member 220 is formed by cutting a part of the tip of the lower housing 213. [ . A locking slit 227 is formed through the lower housing 213 of the locking member 220 to provide an additional space for the locking member 220 to be further deformed in the other direction.

The rotation unit 250 is disposed on one side of the inner bottom surface of the rotary head 251, that is, in the direction of the base unit 210, The engaging jaw 253 is formed to face the engaging member 220. [ When the rotary head 251 is rotated in the winding direction of the rotary head 251 in the fully engaged state, the locking protrusion 253 is inclined with respect to the inclined surface 253b, And a hooking surface 253c that meets in a manner that the hooking member 220 can not be hooked.

Therefore, when the engaging member 220 is overrun or hangs over the engaging jaw 253 and the rotating direction of the rotating unit 250 is not fully engaged or engaged, .

The string adjusting device 200 according to the present invention includes: a first fixing jaw 215 protruding from the inner surface of the lower housing 213; A second fixing jaw (216) spaced apart from the first fixing jaw (215) by a predetermined distance and protruding in parallel with the first fixing jaw (215); A rotary base 270 formed in a plate shape and coupled to one end of the bobbin 260 in a direction away from the rotary head 251 and positioned inside the lower housing 213; And is further protruded from the end portion of the rotation base 270 to be hooked on the first fastening protrusion 215 when the fastener is fully engaged and hooked between the first fastener 215 and the second fastener 216 when the fastener is coupled, And may further include a fixing protrusion 270a.

The rotation unit 250 is fully engaged with the base unit 210 while the fixing protrusion 270a protruding from the end of the rotation base 270 is hooked on the first fixing unit 215 State is maintained. The rotation unit 250 and the base unit 210 are held in a coupled state while the fixing protrusion 270a is hooked between the first fixing jaw 215 and the second fixing jaw 216 .

The first fixing jaw 215 is partially cut to form an insertion groove 215a and the insertion groove 215a can be hooked on the first fixing jaw 215 by passing the fixing protrusion 270a . The fixing protrusion 270a is to be hooked to the lower end of the first fixing protrusion 215 so that the fixing protrusion 270a passes through the insertion groove 215a.

The insertion groove can be formed in the second fixing jaw 216 in the same manner as the first fixing jaw 215.

The fixing protrusion 270a is sandwiched between the upper portion of the first fixing protrusion 215 and the lower portion of the second fixing protrusion 215b. The second fixing jaw 216 is positioned closer to the rotation head 251 by the thickness of the fixing protrusion 270a than the end position of the cord insertion portion 213b in the direction of the base plate 211, (213). Therefore, there is an advantage that the string insertion portion 213 (a) plays the same role as the insertion groove 215a in the first fixing jaw 215. [

In addition, the tension applied to the strap while the strap is wound on the bobbin 260 may be measured. A sensor (not shown), which varies in electrical resistance proportional to the elongation or reduction of the object, such as a strain gauge (not shown), is mounted on the strap or on the latching member 220, (Not shown) capable of reading and transmitting a signal, such as a bridge circuit, can be expressed by changing the elongation or reduction on the string or the latch member 220 by changing the electrical signal. Sensors capable of measuring fine changes in shape in one part of the string adjusting device 200 due to the stretching of the string or the latching member 220 or the resultant effect thereof include strain gauges or capacitive sensors, A magnetic field sensor or an elastomer (not shown). Such characteristics are commonly applicable in all embodiments described throughout this specification.

Hereinafter, the operation of the string adjusting apparatus 200 according to the second embodiment of the present invention will be described in detail.

The user connects the string to the string hook 265 formed on the bobbin 260 of the rotary unit 250 and inserts the string into the string insertion portion 213a of the base unit 210 251 to align the rotating unit 250 with the base unit 210 to be engaged.

At this time, the fixing protrusions 270a of the rotation unit 250 are aligned and engaged so as to pass through the cord insertion portions 213a of the base unit 210. [ When the rotation unit 250 is coupled to the base unit 210, the fixing protrusion 270a is aligned and inserted into the open inlet of the cord insertion unit 213a, When it is rotated in the azimuth direction when it reaches the vicinity of the end in the direction opposite to the entrance, it is positioned between the first fixing jaw 215 and the second fixing jaw 216 and reaches the coupling state. When the fixing protrusion 270a is further rotated in the azimuth angle direction and aligned with the string insertion groove 215c, the rotation unit 250 is further pushed in the direction of the base plate 211 to reach the fully engaged state .

When the rotation unit 250 and the base unit 210 are fully engaged with each other, the engaging member 220 is engaged with the engaging protrusion 253, and when the rotation unit 250 is rotated in this state , The fixing protrusion 270a is supported by the lower end of the first fixing protrusion 215 so that the fixing protrusion 270a can be rotated only in the winding direction of the string.

On the other hand, in a state where the fixing protrusion 270a is placed between the first fixing jaw 215 and the second fixing jaw 215b, Since the direction movement is limited and the engaging member 220 and the engaging jaw 253 do not meet each other, the rotating unit can be freely rotated between both directions in a winding direction and a loosening direction.

The rotation unit 250 can be detached from the base unit 210 when the fixing protrusion 270a is aligned with the string insertion portion 213a and pulled in the direction of the rotary head 251 have.

In the second embodiment, the engaging member 220 of the lower housing 213 and the engaging protrusions 253 of the rotating unit 250 are positioned on the rotating shaft 251, This is a detailed description of the arrangement facing each other.

However, the engaging member 220 and the engaging jaw 253 may be disposed in mutually facing positions while facing each other. For example, if the lower housing 213 is provided with the latching jaws 253 and the latching unit 220 is provided in the rotation unit 250 so as to face each other, the operation principle and operation method of the apparatus, The result of the operation is the same.

In the above description of the second embodiment of the present invention, the position of the latching member 220 is described as the tip of the lower housing 213. However, the latching member 220 is provided on the outer surface of the lower housing 213 (Fig. 19 (a)) or on the inner surface of the lower housing 213 (Fig. 19 (b)).

It is possible to determine whether the engaging member 220 and the engaging jaw 253 are disposed at any one of the rotation unit 250 and the base unit 210 and whether the contact position is an outer wall of the lower housing 213, And the end near the rotating head 251. In the embodiment shown in FIG. The various embodiments of the present invention will be described in detail with reference to the operation principle, the operation method and the operation result of the second embodiment of the present invention described above, as long as the engaging member 220 and the engaging jaw 253 are opposed to each other and face each other. It can be understood that it is the same as the example.

That is, in the above description, the latching jaw 253 and the latching member 220 are arranged to be aligned with the distal end of the lower housing 213, but in reality, the latching jaw 253 and the latching member 220 The inner wall of the lower housing 213 may be disposed at any position along the rails of the cylinder.

The second embodiment of the present invention has been described above. However, the second embodiment of the present invention is different from the first embodiment in that, in the second embodiment of the present invention, 1) the reverse rotation in the direction of pulling- Function can be achieved by a hooking engagement between the latching member 220 and the latching jaw 253; Two functions for preventing the rotation unit 250 from being detached from the base unit 210 when the fixing protrusion 270a of the rotation base 270 and the first and second 2 fixing jaws 215a and 215b, as shown in FIG.

The base plate 311 may have a plate shape or be protruded around the outer surface of the lower housing 313 as in the present embodiment.

Also, the tension applied to the strap (not shown) may be measured while the strap (not shown) is wound around the bobbin 360. For example, a sensor (not shown) is attached on the strap or on the latching member 320, which varies in electrical resistance in proportion to the elongation or reduction of the object, such as a strain gauge (not shown) (Not shown) capable of reading and transmitting a signal, such as a Wheatstone bridge circuit, can be expressed by changing the stretching or reduction on the strap or the latching member 320 into a change in the electrical signal. Sensors capable of measuring a minute shape change of one part of the string adjusting device 300 due to the stretching of the string or the latching member 320 or the resultant effect thereof include strain gauge or capacitance sensor, A field sensor or an elastomer (not shown). Such characteristics are commonly applicable in all embodiments described throughout this specification.

In the second embodiment, the latching slit 227 is formed to penetrate through the lower housing 213. However, in the third embodiment, the latching member 320 is configured such that the latching slits 327a and 327b are engaged with the latching member 320 and the side wall of the lower housing 313 is not penetrated. That is, the stepped groove 329 has a cantilever shape in which the engaging member 320 is coupled to one side surface of the stepped groove 329.

However, the stepped groove 329 is formed by the presence of a part of the cylinder outer wall of the lower housing 313, and part of the outer wall prevents the operation of the engaging member 320 from being visible to the user from the outside, However, in this case, the stepped groove 329 is not provided, but the engagement slit 327a (see FIG. 7) is not provided. In this case, , 327b may be configured to be pierced or openings.

The engaging member 320 is configured to be hooked on the engaging protrusion 353 of the rotating unit 350 and is elastically deformed in the same manner as the second embodiment of the present invention.

According to the third embodiment of the present invention, the first hook protrusion 340 formed on the outer surface of the lower housing 313; And a second hooking protrusion 343 formed on an inner surface of the rotating unit 350 and hooked on the first hooking protrusion 340. The first hooking protrusion 340 and the second hooking protrusion 343 are formed on the inner surface of the rotating unit 350, The rotation unit 350 and the base unit 310 can be rotatably coupled. At this time, the string adjusting apparatus 300 according to the third embodiment of the present invention can be said to be in a fully engaged state.

The first hooking protrusion 340 and the second hooking protrusion 343 may be formed so that a part of the first hooking protrusion 340 and the second hooking protrusion 343 are cut in the azimuthal direction, And their angular positions and angular widths can be formed differently from each other.

13 and 14, the first hooking protrusion 340 is formed along the outer surface of the lower housing 313 of the base unit 310, and the hooking protrusion 340 of the rotation unit 350 And the second hook protrusion 343 corresponding to the first hook protrusion 340 is formed on the inner surface.

A part of the upper end of the second hooking protrusion 343 is hooked on the lower end of the first hooking protrusion 340 when the cord adjusting device 300 is fully engaged.

As shown in FIG. 15, the first and second hook protrusions 340 and 343 are formed in an arcuate shape in cross section, and the most protruded portion of the arc can be formed at the center. That is, the shape of the cross section of the first and second hooking protrusions 340 and 343 may be an exact arc shape.

In FIG. 15, the dotted lines C and C 'represent the centerline of the first and second hooking protrusions 340 and 343, respectively. The most protruding portions of the first and second hooking protrusions 340 and 343 are located on the same line as the centerline .

Referring to FIG. 16, the first and second hooking protrusions 345 and 347 are formed in an arc shape in cross section, and the most protruded portion of the arc is formed at a position shifted to one side with respect to the center of the hooking protrusion .

The difference between the first and second hooking protrusions 340, 343, 345 and 347 according to FIGS. 15 and 16 is in a shape. According to FIG. 16, the most protruding portions of the first and second hooking protrusions 345 and 347 And is formed at a position offset to the lower side. (Not shown) such that the most protruding portions of the first and second hooking protrusions 345 and 347 are formed at positions offset in the direction of the rotary head 351 with respect to the center line thereof. This is to improve the first hooking protrusion 345 and the second hooking protrusion 347 when the hooks are mutually engaged and the binding force adjustment between the hooking protrusions 345 and 347 when necessary.

Meanwhile, although the first and second hooking protrusions 345 and 347 have been described with respect to the example of hooking protrusions having both protruding shapes, it is not necessary to be limited to the example of such a protruding shape. The hooking protrusion of one of the first and second hooking protrusions 345 and 347 is formed in a ring groove or a trench recessed along the circumference and the other hooking protrusion is protruded, .

Referring to FIG. 15, the third embodiment includes a through hole 311a communicating with the lower housing 313 and penetrating through the base plate 311; And a hook 311b formed along the inner surface of the through hole 311a and selectively hooked to the upper end of the rotary base 370. [

16 shows the fully engaged state, in which the second hooking protrusion 343 is positioned further toward the base plate 370 than the first hooking protrusion 340. At the same time, the hooking jaw 311b and the base plate 370 are not in contact with each other and a separation distance is generated.

18, the hooking jaw 311b may be formed by forming a step on the inner wall of the lower housing 313 near the entrance of the base plate 311 of the through hole 311a if necessary .

The bobbin 360 may be positioned at the end of the bobbin 360 in the direction of the base plate 311 and the rotation base 370 may be coupled to the end of the string adjusting device 300 And is hooked on the hooking jaw 311b.

This ensures that the rotation unit 350 and the base unit 310 are completely separated from each other even when the first and second hooking protrusions 340 and 343 are disengaged by allowing the rotation base 370 to be hooked on the hooking protrusion 311b. So as not to be separated.

As shown in FIG. 17, the first hook protrusion 340 formed on the outer surface of the lower housing 313; A second hooking protrusion 343 formed on an inner surface of the rotating unit 350 and hooked on the first hooking protrusion 340; A through hole 311a communicating with the lower housing 313 and penetrating through the base plate 311; And a hooking protrusion 311b formed along the inner surface of the through hole 311a and selectively hooked to a surface of the rotating base 370 in the direction of the rotary head 351. The first hooking protrusion 340, While the rotary base 370 is kept in contact with a part of the end of the second hooking protrusion 343 in the direction of the rotating head 351 and a part of the end of the second hooking protrusion 343 in the direction of the base plate 311, Can be hooked on the base 311b.

This prevents the first hooking protrusion 340 and the second hooking protrusion 343 from being completely separated from each other when the rotary base 370 is hooked on the hooking protrusion 311b, The rotation unit 350 is prevented from being completely separated from the base unit 310 when the base unit 310 rotates relative to the base unit 310.

In all the embodiments described above, the cord insertion portions 113d, 213a, and 313a are represented by through-holes or openings having a U-shaped shape while being opened in one direction. However, There is no need, and all the openings that can be formed by a circle or a polygon or a combination of all curves and straight lines can exhibit its function.

On the other hand, the string adjusting apparatuses of all the embodiments described throughout the present specification are characterized in that they have a feature that the thickness, the width, or the width are largely different from each other, and can be applied to all kinds of objects having a characteristic of bending down In the case of bands, in the string adjusting devices of all of the embodiments described throughout this specification, the strap inserts, And the length of the bobbin is set according to the width of the band, it is easy to deduce that it has a function of winding and storing the band.

Conventional commercial product string adjusters (not shown), such as existing trekking shoes, all use a metal wire synthetic resin covering cord (not shown) coated with synthetic resin coating such as plastic around the inner core of the metallic wire. Although the metal wire synthetic resin covering cord has an advantage of high tensile strength, it has a serious disadvantage that it can not perform a rolling action by a sharp angle.

Such disadvantages are that 1) it is troublesome to attach a separate string guide part (not shown) to the shoe other than the string adjusting device when it is used in shoes, and 2) the diameter of the bobbin in the string adjusting device should be made small It will be subject to restrictions. Therefore, it was difficult to escape from the limitation of the thickness of the conventional string control device which is large in diameter.

On the other hand, the string adjusting devices of all the embodiments described all over this specification are not limited to the nylon, polyester, cotton, wool, and the like, as well as being capable of producing the diameter and thickness of the metal wire- And so the string adjusting device of the present invention can be manufactured with a small diameter and a thin thickness so that it can be made thin and small It is suitable for a wide range of products requiring string adjusters.

In addition, the string adjusting devices of all embodiments described throughout the specification have the advantage that one or more strings can be simultaneously worn on the string insertion portion and the bobbin. In more detail, if the total thickness of the straps on the bobbin is small enough to be accommodated by the diameter of the string insertion portion or the size of the space of the string insertion portion of the bobbin, It has the only advantage that it can be wound on.

In addition, the string adjusting devices of all the embodiments described throughout the present specification can be used to adjust the length of the string to 1) all the industrial formulations whose characteristics such as shape or structure need to be modified, or 2) Can be applied to any product family requiring intentional adjustment of the properties to which contact with the exterior is connected.

In addition, the string adjusting apparatuses of all the embodiments described throughout the present specification include a storage space for a strap entering and leaving through the string insertion portions 113d, 213a, and 313a, and a locking function for adjusting opening and closing All wearing products that require a cord storage enclosure function can be applied to all industrial product categories.

Typical examples of such a product family include: 1) shoes, 2) clothes (including underwear and pants, outdoor jackets, padding, gowns, raincoats, etc. including bra, corsets, 4) gloves, 5) belts and belts, 6) bags, 7) various jewelery including necklaces, pennants, etc. 8) support or guard 9) musculoskeletal support or orthodontic wear 10) Bedding products including mattress covers, pillow covers, and cushions, 12) household items requiring adjustable lengths such as hangers and storage shelves, 13) lanyards such as earphones, (14) a tent, (15) a housing for various tapes and rolls, (16) an umbrella, a canopy, and the like.

Accordingly, the following description of the implementation concept in which the string adjustment devices of all embodiments described throughout this specification are applied to the above listed product families. The principle of operation is as follows.
