Description

Reel structure

The present disclosure relates to a reel structure. More specifically, the present disclosure relates to a reel structure that can quickly tighten and loosen a string.

In everyday life, strings such as strings or threads are used to fasten objects. The most common method of fastening is to repeatedly pass a line through the hole in an object, and then tie the knot to secure the object. However, in this kind of tightening method, the knot is easily released by an external force. This not only ties up the knot again, but also leads to a lot of inconvenience because of the instability of the object.

To solve such problems, some industry practitioners have developed a rotatable buckle to fasten and secure the straps. Through interference between the parts inside the buckle, the length of the strap as well as the tightened condition can be adjusted. However, since the interference force between the parts must be overcome while pulling the strap backward, the tightening speed is slow and consequently time is wasted. Thus, the string can only be released by pulling and can not be released by rotation, thus limiting the manner in which it is released.

Based on the problems of the prior art described above, the present disclosure is directed to providing a reel structure that can effectively improve the tightening speed of the buckle and improve usability.

According to an aspect of the present disclosure, a reel structure for tightening or loosening a string includes a case, a knob, a fixing unit, and a spool. The case includes a base, a wall, a claw, and an annular gear. The wall extends from the base and forms a space with the base. The tongs are arranged inside the space and protrude from the base toward the space. The annular gear is disposed on the wall and facing the space. The knob covers the case. The fixing unit is disposed inside the space. One end of the fixing unit is connected to the knob. The fixing unit includes a first restriction portion, a second restriction portion, and an arm. The second restricting portion is disposed apart from the first restricting portion. The tongs are selectively coupled to the first restricting portion or the second restricting portion. The arm is engaged with the annular gear to prevent the knob from rotating in the unwinding direction relative to the case. The arm is radially released from the annular gear in the tightening direction opposite to the unwinding direction. The spool is disposed inside the space. Thus, the spool is connected to the fixed unit and rotated together with the fixed unit. The string is wound around the spool and connected to the spool. The fastening unit has a first position and a second position relative to the case. When the fixing unit is in the first position, the clamp is coupled to the first restriction. The spool is connected to the knob and is rotated in the tightening direction to fix the string. When the fixing unit is in the second position, the clamp is coupled to the second restricting portion. The arm is released from the annular gear. When the string is pulled out to the side, the spool is connected to the knob and rotated in the unwinding direction.

According to another aspect of the present disclosure, a reel structure for fixing and releasing a string includes a case, a knob, a fixing unit, and a spool. The case has a base, a wall, and an annular gear. The wall extends from the base and forms a space with the base. The annular gear is placed on the wall and facing the space. The knob covers the case. The fixing unit is disposed inside the space. One end of the fixing unit is connected to the knob. The fixing unit has an arm. The arm is coupled to the annular gear to prevent the knob from rotating in the unwinding direction relative to the case. The arm is radially released from the annular gear in the tightening direction opposite to the unwinding direction. The spool is disposed inside the space. The spool is connected to the fixed unit and rotated together with the fixed unit. The string is wound around the spool and connected to the spool. The fastening unit has a first position and a second position with respect to the case. When the fastening unit is in the first position, the arm is released from the annular gear, and when the strap sideways, the spool is connected to the knob and rotated in the unwinding direction.

1 is a perspective view of a reel structure 100 according to one embodiment of the present disclosure. Fig. 2 is an exploded perspective view of the reel structure of Fig. 1; 3 is another exploded perspective view of the reel structure 100 of FIG. 1 to 3, the reel structure 100 includes a case 200, a spool 300, a fixing unit 400, and a knob 500 for fixing and releasing a string (not shown) .

The case 200 includes a base 210, a wall 220, and an annular gear 250. The wall 220 extends from the base 210 and forms a space 230 with the base 210. The annular gear 250 is formed inside the wall 220 to face toward the space 230. The knob 500 covers the case 200. The fixing unit 400 is disposed in the space 230 and one end of the fixing unit 400 is coupled to the knob 500. The fixing unit 400 includes an arm 422, and the number of the arms 422 is four in the present embodiment, but is not limited thereto. The arm 422 is coupled to the annular gear 250 to prevent the knob 500 from rotating in the releasing direction A1 with respect to the case 200 and the arm 422 is fastened in the opposite direction to the releasing direction A1 Is released radially from the annular gear 250 in the direction A2.

The spool 300 is disposed inside the space 230. The spool 300 is coupled to the fixing unit 400 and rotated together with the fixing unit 400. The string is connected to the spool (300) and wound around the spool (300). The fixing unit 400 has a first position and a second position with respect to the case 200. When the fixing unit 400 is in the first position, the spool 300 is connected to the knob 500 to rotate in the tightening direction A2 to fix the string. When the fastening unit 400 is in the second position, the arm 422 is released from the annular gear 250 and the strap is pulled sideways and the spool 300 is connected to the knob 500 to be pulled out in the unwinding direction A1 Rotate.

The above-described structure makes it easy to change the state of fastening or loosening of the strap, and facilitates securing the function of fine adjustment of tightness. The engagement between the arm 422 and the annular gear 250 prevents loosening of the strap to achieve the purpose of tightening the strap. Since the knob 500 rotates while loosening or fixing the string, the loosening and fixing state of the string can be clearly understood from the rotating direction of the knob 500. [ The detailed structure and motion of this embodiment are described in further detail in the following paragraphs.

More specifically, the present embodiment further includes a claw 240 in addition to the base 210, the wall 220, and the annular gear 250. The number of tongs 240 is three in the present embodiment, but is not limited thereto. The base 210 includes a hole 211 (see FIG. 3) that communicates with the space 230. The clamp 240 is disposed around the hole 211 and protrudes from the base 210. That is, the tongue 240 protrudes toward the space 230.

The spool (300) is a ring structure including an external gear (310) and a fixing member (320). The securing member 320 is for securing the two ends of the strap to prevent release of the strap from the spool 300. The string may be regularly wound around the spool 300 and pulled or released based on the other rotational direction of the spool 300. [

The fixing unit 400 includes a connecting member 410, a fixing member 420, and a moving member 430. The arm 422 is disposed on the fixing member 420.

The connecting member 410 is disposed inside the knob 500 and coupled to the knob 500. The connecting member 410 includes an upper hole 411, a lower hole 413 (see FIG. 3), and two engaging portions 412. Both the upper hole 411 and the lower hole 413 are hexagonal prismatic. The coupling portion 412 is located at one end of the coupling portion 410 facing toward the knob 500. The two engaging portions 412 are correspondingly disposed and engaged with the fixing member 420.

The fixing unit 420 has an arm 422, a ring body 421 and an internal gear 423 (see Fig. 3). The ring body 421 is sleeve-coupled to the connecting member 410. The arm 422 protrudes outside the ring body 421. The internal gear 423 is disposed inside the ring body 421. Since the shape of the internal gear 423 corresponds to the external gear 310, the internal gear 423 can be coupled to the external gear 310.

The shifting member 430 includes a pillar 433, a first restricting portion 431 and a second restricting portion 432. The column 433 is for coupling to the connecting member 410. The first restricting portion 431 and the second restricting portion 432 are disposed at predetermined intervals along the axis of the column 433. One end of the column facing toward the knob 500 includes a cap 434. The cap 434 is in the shape of a hexagonal prism and corresponds to the shape of the lower hole 413.

One end of the knob 500 facing toward the case 200 includes a hollow 540 hollow and a prism 530 (see FIG. 3). The prism 530 is in the shape of a hexagonal prism and includes a through hole 520. The prism 530 is disposed so as to protrude from the center of the hollow 540. The through hole 520 penetrates the knob 500.

When the reel structure 100 is assembled, first, the fixing member 420 is disposed on the upper side of the spool 300. The coupling member 410 is inserted into the fixing member 420 from the lower side of the spool 300 and is coupled to the ring body 421 through the coupling portion 412. [ do. As a result, assembly of the connecting member 410, the fixing member 420, and the spool 300 is completed. When the connecting member 410, the fixing member 420 and the spool 300 are disposed inside the space 230, the tongue 240 protrudes inward of the spool 300. The movable member 430 coming out from the lower side of the case 200 can pass through the hole 211 so that the clamp 240 can be coupled to the first restricting portion 431 or the second restricting portion 432. [ Since the shape of the cap 434 corresponds to the shape of the lower hole 413, the cap 434 is engaged with the lower hole 413, so that the assembly of the case 200, the fixing unit 400 and the spool 300 Can be completed. The knob 500 covers the cover 200 so that the prism is coupled to the upper hole 411 and the fixing member 420 is coupled to the hollow 540. The reel structure 100 can be fully assembled by attaching the screw 510 to the through hole 520. The assembly process is only exemplary and the present disclosure is not limited thereto. The fixed unit may be a single-element, but is not limited thereto.

FIG. 4 is a cross-sectional view of the reel structure along line 4-4 in FIG. 1, and FIG. 5 is another cross-sectional view of the reel structure 100 of FIG.

Referring to Figures 4 and 5 in conjunction with Figures 2 and 3, the knob 500 of the reel structure 100 has a central axis I1. The knob 500 can be pulled along the central axis I1 and fixed by moving the fixing unit 400 upward. Accordingly, the fixing unit 400 can have the first position and the second position with respect to the case 200. [ As shown in FIG. 4, when the fixing unit 400 is in the first position, the clamp 240 is coupled to the first restricting portion 431. As shown in FIG. 5, when the knob 500 is pulled upward, the clamp 240 is coupled to the second restricting portion 432 and the securing unit 400 is in the second position.

Interference occurs between the arm 422 and the annular gear 250 when the fixing unit 400 is in the first position and the clamp 240 is engaged with the first limiting portion 431 (see FIG. 2). Since the arm 422 has elasticity, when the fixing unit 400 is connected to the knob 500 and rotates in the fixing direction A2, the arm 422 will be gradually released from the annular gear 250 and released . In other words, the arm 422 can not prevent rotation of the knob 500 in the fixing direction A2. Accordingly, the knob 500 can rotate the fixing unit 400 and the spool 300 in the fixing direction A2 to fix the string. On the other hand, in order to prevent the knob 500 from rotating in the unwinding direction A1 with respect to the case 200 when the knob 500 rotates toward the unwinding direction A1, the arm 422 is rotated by the annular gear 250 ), So that the string can not be pulled. Thus, as shown in FIG. 4, the reel structure 100 can only secure a string. The string will not automatically loosen when the user releases his / her hand from the rotating knob 500, because the string's fastening speed is slow as a result of interference between the arm 422 and the annular gear 250. Therefore, the tension of the string can be finely adjusted.

As shown in FIG. 5, the fixing unit 400 is in the second position and the clamp 240 is coupled to the second limiting portion 432. The arm 422 is remote from the case 200 and is released from the annular gear 250. The knob 500 can be rotated with respect to the case 200 in the unwinding direction A1 or the fixing direction A2. Since the external gear 310 is still coupled to the internal gear 423, the spool 300 is still connected to the knob 500. The knob 500 will rotate together while the string is being pulled. At this time, the knob 500 can be used to pull the string or rotate it in the other direction to release the string. When the strap obtains the predicted length, the knob 500 is pushed downward to convert the fastening unit 400 to the first position to secure the strap.

The first restricting portion 431 is an outer annular groove disposed on the column 433 and the second restricting portion 432 is another annular groove disposed on the column 433. In this embodiment, The clamp 240 includes a protrusion 241 corresponding to the outer annular grooves. In another embodiment, the forceps may include a recess, and both the first and second restricting portions may be protruding rings disposed on the posts. The protruding ring can be engaged with the recess.

4, the height d2 of the external gear 310 parallel to the center axis I1 is larger than the height d1 of the arm 422 parallel to the center axis I1. Thus, when the fixing unit 400 is in the first position and the second position, the external gear 310 is engaged with the internal gear 423. The knob 500 may be connected to the spool 300 at both the first and second positions.

FIG. 6 is a perspective view of a reel structure 100a according to another embodiment of the present disclosure, FIG. 7 is an exploded perspective view of the reel structure 100a of FIG. 6, It is a perspective view. 6 to 8, the reel structure 100a is similar to the reel structure 100 of the embodiment described with reference to Figs. 1 to 5, but has a slight difference in structure.

The reel structure 100a includes a case 200a, a spool 300a, a fixing unit 400a, and a knob 500a. The fixing unit 400a includes a fixing member 420a and a moving member 430a. 8), the prism 424 (see FIG. 8), and the opening 425 (see FIG. 8). The fixing unit 400a includes a ring body 421a, four arms 422a, an internal gear 432a ). The arms 422a, the internal gear 432a, and the prism 424 are disposed in the ring body 421a. The prism 424 protrudes toward the spool 300a, and the opening 425 is disposed in the prism 424. The structures of the case 200a, the spool 300a, and the moving member 430a are similar to the embodiments disclosed in Figs. In this embodiment, the cap 434a is engaged with the moving member 430a to couple the moving member 430a to the fixing member 420a.

9 is a cross-sectional view of the reel structure 100a along line 9-9 of Fig. 6, and Fig. 10 is another cross-sectional view of the reel structure 100a of Fig. In this embodiment, the knob 500a can be pulled upward along the central axis I2. Through the axial movement of the knob 500a, the fixing unit 400a can have a first position and a second position with respect to the case 200a.

As shown in Fig. 9, the fixing unit 400a is in the first position when the knob 500a is not pulled. The arm 422a is engaged with the annular gear 250a (see Fig. 7). Since the arms 422a can be released from the annular gear 250a in the fixed direction A2, the rotation of the knob 500a causes the spool 300a to rotate in the fixed direction A2 Can be accepted. Since the arms 422a can not be released from the annular gear 250a in the unwinding direction A1, the string is fixed. The object of pulling the string, adjusting the fine tension of the string and fixing the string is achieved.

10, when the knob 500a is pulled, the fixing unit 400a is in the second position and is released from the annular gear 250a by separating the arms 422a from the case 200a. The internal gear 423a is still coupled to the external gear 310a (see Fig. 7). The string is pulled to the side so that the spool is coupled to the knob 500a and is rotated toward the unwinding direction A1 to release the string. The knob 500a can be quickly rotated toward the fixing direction A2 to pull the string.

9, the height d2 of the external gear 310a parallel to the central axis I2 is larger than the height d1 of the arm 422a parallel to the center axis I2. Thus, when the fixing unit 400a is in the first position or the second position, the external gear 310a is engaged with the internal gear 423a. Knob 500a may be connected to spool 300a at both the first and second positions.

Through the above-described embodiments, the present disclosure has the following advantages.

1. Due to the connection between the knob and the spool, the purpose of quickly pulling the string or releasing the string is obtained by rotating the knob toward the other directions.

2. Since the fastening unit has the first position and the second position with respect to the case, not only the fastening or unfastening state of the strap can be changed, but also the fastening of the strap or the fine adjustment function of the tension can be selected. When the fixing unit is in the first position, the tension can be adjusted because the fixing speed of the string is slow. When the fastening unit is in the second position, the knob can be quickly rotated to quickly pull the strap.

3. Through the relationship that the height of the external gear is greater than the height of the arms, the external gear is engaged with the internal gear when the fixing unit is in the first position or the second position. Thus, the knob can be connected to the spool in both the first and second positions.

It will be apparent to those skilled in the art that various modifications and variations can be made in the structure of this disclosure without departing from the spirit and scope of the disclosure. In view of the foregoing, this disclosure is intended to cover various modifications and variations of this disclosure insofar as they come within the scope of the following claims.
