Description

Technical Field

[0001] This invention relates to a length adjustment component for linear bodies. Background Technology

[0002] As linear elements used in clothing, for example, there are shoelaces, but the length of shoelaces used to be adjusted by a special knotting method, such as tying a bow.

[0003] However, this special knotting method has problems such as being impossible for children to perform, being impossible to adjust with one hand, and being difficult to adjust while wearing gloves.

[0004] As a means of solving this problem, Patent Document 1 discloses a rope having a tubular rope body made of a stretchable material and having knots that are repeatedly arranged at intervals and whose diameter varies depending on the magnitude of the axial tension applied to it.

[0005] Therefore, because the knot, whose diameter changes, engages with the eyelet of the shoe, the user can adjust the length of the shoelaces without using a special knotting method such as tying a bow.

[0006] Furthermore, Patent Document 2 discloses a spring-loaded cord stopper. By installing this cord stopper on the shoelaces, the user can adjust the length of the shoelaces without using a special knotting method such as tying a bow.

[0010] Patent Document 2: Japanese Utility Model Application Publication No. 5-34907 Summary of the Invention

[0011] [The problem the invention aims to solve]

[0012] However, while the rope described in Patent Document 1, which has a tubular rope body made of a stretchable material and has knots that can change size, can be operated with one hand, it lacks a locking / unlocking function for shoelaces at any position because its length can only be adjusted by the intervals of the knots that change size. Therefore, it is difficult to fine-tune it according to the user's preferences.

[0013] Furthermore, while the spring-loaded cord stop described in Patent Document 2 has a locking / unlocking function for shoelaces at any position, the user needs to operate the cord stop with one hand and adjust the length of the shoelaces with the other. Essentially, the user needs to use both hands to adjust the shoelace length, increasing the time required for this operation.

[0014] The present invention was made in view of the above-mentioned problems, and its object is to provide a length adjustment member for a linear body that, compared with conventional length adjustment members for linear bodies, requires less operation time for adjusting the length of shoelaces, and has a locking / unlocking function at any position desired by the user.

[0015] [Methods used to solve problems]

[0016] To achieve the above objectives, the invention described in technical solution 1 of this invention is a length adjustment member for a linear body, comprising a main body component and a cover component displaced relative to the main body component. The main body component has: a first through hole; a second through hole disposed on one side of the first through hole; and a third through hole disposed on the other side of the first through hole. The main body component also has: a first rod disposed between the first and second through holes; and a second rod disposed between the first and third through holes. The cover component has a locking member inserted into the first through hole, which presses the linear body between itself and the first rod and between itself and the second rod.

[0017] Based on the structure of the invention described in technical solution 1, the invention described in technical solution 2 is characterized in that it has a recessed portion in the upper surface of the main body member, in the vertical direction of the portion where the cover member is located, the second rod is located below the recessed portion and is located below the first rod, and the upper surface of the main body member and the upper surface of the cover member are smoothly continuous when locked.

[0018] Based on the structure of the invention described in technical solution 1 or 2, the invention described in technical solution 3 is characterized in that the locking member is provided at one end of the cover member in the front-rear direction, and an operating protrusion for operating the cover member is provided at the other end of the cover member in the front-rear direction, the operating protrusion extending toward the other side in the front-rear direction.

[0019] Based on the structure of the invention described in technical solutions 1 to 3, the invention described in technical solution 4 is characterized in that the width of the locking member in the left-right direction is narrower than the width of the first through hole in the left-right direction.

[0020] Based on the structure of the invention described in technical solutions 1 to 4, the invention described in technical solution 5 is characterized in that a protrusion for operating the length adjustment member is provided at one end of the main body member in the front-rear direction, and the protrusion extends toward one side in the front-rear direction.

[0021] Based on the structure of the invention described in technical solution 1, the invention described in technical solution 6 is characterized in that, when unlocking, the locking member and the second rod are used to clamp the line body.

[0022] Based on the structure of the invention described in technical solution 1, the invention described in technical solution 7 is characterized in that the main body component has a third rod approximately in the center in the left-right direction, the third rod extends in the front-back direction and divides the first through hole, the second through hole and the third through hole into two parts in the left-right direction, and the locking component has a locking component notch for the third rod to pass through.

[0023] Based on the structure of the invention described in technical solution 1, the invention described in technical solution 8 is characterized in that the cover member is displaced in the vertical direction relative to the main body member.

[0024] [Invention Effects]

[0025] The connecting structure of the present invention is the structure described above, and the following effects are achieved by using this structure.

[0026] The invention described in technical solution 1 of this invention has the above-mentioned structure, and therefore can provide a length adjustment member for a linear body, which, compared with conventional length adjustment members for linear bodies, requires less operation time for adjusting the length of shoelaces, and has a locking / unlocking function at any position desired by the user.

[0027] The invention described in technical solution 2 of this invention has the above-mentioned structure, so the main component can receive a portion of the thickness of the cover component in the vertical direction, thus making the thickness of the length adjustment component of the line body in the vertical direction thinner.

[0028] The invention described in technical solution 3 of this invention has the above-mentioned structure, thus preventing the thickness of the length adjustment component of the line body from increasing in the vertical direction.

[0029] The invention described in technical solution 4 of this invention has the above-mentioned structure, so that even after the main body component and the cover component are connected, the line body can still pass through.

[0030] The invention described in technical solution 5 of this invention has the above-mentioned structure. Therefore, when lifting the length adjustment member of the line body, the length adjustment member of the line body can be easily pinched, and the thickness of the length adjustment member of the line body in the vertical direction can be prevented from increasing.

[0031] The invention described in technical solution 6 of this invention has the above-described structure, thus enabling easy one-handed operation of the line length adjustment component.

[0032] The invention described in technical solution 7 of this invention has the above-mentioned structure, thus enabling the line body to be folded back (forming a loop) and the length of the line body to be easily adjusted.

[0033] The invention described in technical solution 8 of this invention has the above-described structure, thus enabling the force applied from the cover member to the line body to be uniform.

[0034] As described above, according to the present invention, a length adjustment member for a line body can be provided that, compared with conventional length adjustment members for line bodies, requires less operation time for adjusting the length of shoelaces, and has a locking / unlocking function at any position desired by the user.

[0063] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments are not independent of each other and require no further explanation. Anyone skilled in the art can appropriately combine the embodiments and understand the combined effects. Repeated descriptions between embodiments are omitted in principle.

[0064] The directions are defined as follows: The left-right direction is along the axis of the first rod of the main component described later, i.e., the direction of the short side of the length adjusting member. The front-back direction is the direction of the long side of the length adjusting member, orthogonal to the left-right direction. The up-down direction is the direction orthogonal to both the left-right and front-back directions. Furthermore, the directions may be redefined in other ways based on the overall disclosure of this application.

[0065] <First Implementation>

[0066] Reference Figures 1 to 14 The first embodiment of the present invention will be described below.

[0067] The length adjustment component 1 consists of a main body component 10 and a cover component 20 that can be connected or separated. Figures 1 to 5 This is a diagram showing the connection between the main component 10 and the cover component 20.

[0068] The size of the length adjustment piece 1 varies depending on the width of the line body S and its purpose. However, when the purpose is to adjust the flat rope (band-shaped rope) of a shoe, it is preferable that the length of the length adjustment piece 1 is about 11 mm in the left-right direction, about 22.5 mm in the front-back direction, and about 5.3 mm in the vertical direction.

[0069] (Main Component 10)

[0070] The main component 10 is formed using thermoplastic resins such as polyamide, polyacetal, polypropylene, polyethylene terephthalate, polyethylene, and polyurethane, for example... Figures 6 to 8 As shown, the main body component 10 includes a main body component 11, a shaft portion 13 connected to the bearing portion 24 of the cover component 20, a notch portion 14 for allowing the line body S to pass through easily, a first rod 15 and a second rod 16 for holding the line body S, and a protrusion 17 for hooking the finger when the length adjustment member 1 is moved.

[0071] Furthermore, the main component 11 has three holes formed by the first rod 15 and the second rod 16: the first through hole H1, the second through hole H2, and the third through hole H3.

[0072] like Figure 8 As shown, the shaft portion 13 has a guide surface 13a formed on its upper side in the vertical direction for guiding the inner side of the drooping portion 23 of the cover member 20 described later.

[0073] Additionally, although not shown in the figure, the shaft portion 13 may also have protrusions, such as those that engage with grooves, on or near the outer peripheral surface of the bearing portion 24 of the cover member 20 described later. These protrusions, etc., can be used to limit the rotation range of the cover member 20.

[0074] like Figure 6 As shown, the portion of the main body 11 located around the shaft portion 13 has a shape in which its width in the left-right direction is recessed inward compared to the other portions of the main body 11. Due to this structure, the drooping portion 23 of the cover member 20, described later, can enter the recessed portion.

[0075] Therefore, when connecting the main body component 10 and the cover component 20, as follows: Figure 1 As shown, this allows the end face in the width direction to be a smooth, continuous structure (flush).

[0076] like Figure 7 As shown, the portion of the upper surface of the main body 11 where the cover body 21 is located is a recessed portion 11a whose width in the vertical direction is recessed downwards compared to the other portions of the main body 11.

[0077] In addition, such as Figure 13 and Figure 14 As shown, the second rod 16 is located below the recess 11a and is positioned lower than the first rod 15. That is, there is a height difference G between the upper end of the first rod 15 and the upper end of the second rod 16.

[0078] Therefore, the upper surfaces of the main body member 10 and the cover member 20 can be made into a smooth, continuous structure (flush) when locked.

[0079] like Figure 6 and Figure 13 As shown, the first rod 15 has a locking part 12 formed on the side of the first through hole H1 and at a position corresponding to the first locking part 22a of the cover member 20 described later, for engaging with the first locking part 22a.

[0080] In addition, such as Figure 6As shown, the second rod 16 has a notch 14 formed on the side of the third through hole H3, at a position that does not correspond to the first locking part 22a of the cover member 20 described later. If the maximum value of the width in the front-back direction of the hole corresponding to the notch 14 in the third through hole H3 is set as D1, and the maximum value of the width in the front-back direction of the hole corresponding to the part of the third through hole H3 without the notch 14 is set as D2, then D1 is slightly larger than D2. When considering the case where the length adjustment member 1 is used to adjust the length of the shoelace, a rod-shaped fixing part (a rod-shaped fixing part provided for passing through the shoelace through hole of the shoe) is usually provided at the front end of the shoelace. Therefore, if the notch 14 is not provided as in this embodiment, the upper limit of the diameter of the rod-shaped fixing part that can pass through the third through hole H3 is D2. However, by providing the notch 14 as in this embodiment, the upper limit of the allowable range of the diameter of the rod-shaped fixing part that can pass through can be increased from D2 to D1. Furthermore, while achieving this effect, by locally providing the notch 14 in this way, it is not necessary to reduce the overall width of the second rod 16 (meaning it is not necessary to reduce the overall width to the width of the portion containing the notch 14), thus maintaining the overall strength of the second rod 16. Additionally, in order to maintain the overall width of the second rod 16 (meaning to maintain the overall width of the second rod 16 at the width of the portion without the notch 14) and maximize the width of the third through hole H3 to D1, it is necessary to extend the third through hole H3 towards... Figure 6 The top of it expands, but if it is set up this way, then... Figure 6 The portion represented by R1 will necessarily become longer (D1-D2). When R1 increases, Figure 10 The radius of rotation R2 of the cover member 20 shown also needs to be increased (if it is not increased, the cover member 20 cannot rotate around the shaft 13, thus...). Figure 4 As shown, the cover member 20 cannot be opened, resulting in an increase in the overall thickness (thickness in the vertical direction) of the length adjustment member 1, which compromises the compactness of the length adjustment member 1. Furthermore, for convenience, R1 is referred to as the length of the limiting portion of the rotation radius of the cover member 20.

[0081] By utilizing the notch 14, when unlocking, even when the gap formed between the cover member 20 and the second rod 16 is small, the side line of the second rod S2 can easily pass through. In particular, when the side line of the second rod S2 is a shoelace, the rod-shaped fixing part provided at the front end of the shoelace can easily pass through.

[0082] (Cover component 20)

[0083] Similar to the main body component, the cover component 20 is formed using thermoplastic resins such as polyamide, polyacetal, polypropylene, polyethylene terephthalate, polyethylene, and polyurethane, for example... Figures 9 to 12As shown, the cover member 20 comprises a cover member body 21, a locking member 22 that enters the first through hole H1 of the main body member 11, a hanging portion 23 hanging down from the upper surface of the cover member body 21, a bearing portion 24 provided on the hanging portion 23 for receiving the shaft portion 13 of the main body member 10, an operating protrusion 25 for hooking a finger when the cover member 20 is opened and closed or when the length adjustment member 1 is moved, and a reinforcing portion 26 for increasing the strength of the hanging portion 23. The reinforcing portion 26 is thicker than the portion of the hanging portion 23 where the bearing portion 24 is provided, and a pair of reinforcing portions 26 are provided on both sides of the bearing portion 24 in the front-rear direction (in Figure 12 (Only one side of the figure is marked with reference numerals). Alternatively, a suitable opening may be provided in the center of the upper surface of the cover member body 21, through which the side line body S2 of the second rod can be visually viewed.

[0084] like Figure 10 As shown, the locking member 22 has a first locking part 22a and a second locking part 22b, and is configured such that, in Figure 13 The locking position shown is such that the first rod side line body S1 is clamped by the first locking part 22a and the first rod 15 of the main body member 10, and the second rod side line body S2 is clamped by the second locking part 22b and the second rod 16 of the main body member 10. Furthermore, only one locking member 22 is provided in this embodiment, but it can also be provided in multiple forms.

[0085] In addition, such as Figure 1 As shown, the locking member 22 is formed to be approximately half the width of the first through hole H1 in the left-right direction. Therefore, when unlocking, the side without the locking member 22 can be used when the second rod side member S2 passes through the second rod 16. That is, when unlocking, if the gap formed between the cover member 20 and the second rod 16 is small, it may be difficult for the front end of the second rod side member S2 to pass through the second rod 16 (especially if a rod-shaped fixing part is provided, such as the front end of a shoelace), but even in such cases, the second rod side member S2 can pass through.

[0086] Additionally, although not shown in the figure, a groove or similar element that engages with a protrusion or similar element provided on or near the inner circumferential surface of the bearing portion 24 can be provided. This groove or similar element can be used to limit the rotation range of the cover member 20.

[0087] (Assembly method for length adjustment part 1)

[0088] The assembly method of the length adjustment part 1 of the line body S is explained.

[0089] The assembly method is simply to press the cover member 20 into the main body member 10 from the upper side to the lower side in the vertical direction so that the bearing portion 24 of the cover member 20 is embedded into the shaft portion 13 of the main body member 10.

[0090] When the cover member 20 is pressed in from the upper side to the lower side in the vertical direction, the inner side of the drooping part 23 expands along the guide surface 13a of the shaft part 13, and then the bearing part 24 is inserted into the shaft part 13, thereby completing the connection between the two.

[0091] (How to lock the line body S)

[0092] The method of using the length adjustment component 1 of the line body S, especially the method of locking the line body S, is explained.

[0093] First, by pressing the operating tab 25 from the upper side to the lower side in the vertical direction, the cover member 20 is moved towards... Figure 14 The unlocked position shown has been moved.

[0094] Then, when the line body S is first placed on the length adjustment member 1, the front ends (free ends) of the first rod side line body S1 and the second rod side line body S2 pass through the length adjustment member 1.

[0095] Specifically, such as Figure 14 As shown, the first rod side line S1 passes through the first through hole H1 from the lower side to the upper side in the vertical direction, and then passes through the second through hole H2 from the upper side to the lower side via the upper surface of the first rod 15. In this way, since the first rod side line S1 is wound around the main body 10 in such a way that it bears frictional force between the upper surface of the first rod 15 and the lower surface of the main body 11, even when locked, if the front end (free end) of the first rod side line S1 is pulled strongly by an external force, the line S is not easily loosened due to the aforementioned frictional force. Furthermore, even when unlocking, the line S will not suddenly and unexpectedly loosen due to the aforementioned frictional force.

[0096] Moreover, such as Figure 14 As shown, the second rod side line S2 passes through the first through hole H1 from the lower side to the upper side in the vertical direction, and then passes through the upper surface of the second rod 16 from the upper side to the lower side in the vertical direction of the third through hole H3. In this way, the second rod side line S2 is wound around the main body 10 in such a way that the upper surface of the second rod 16 and the lower surface of the main body 11 are subjected to frictional force. Therefore, similar to the case of the line S1, the advantageous effect of the line S2 not being easy to loosen can be obtained.

[0097] Furthermore, the timing for passing the first rod side line body S1 and the second rod side line body S2 through the length adjustment member 1 can also be before assembling the length adjustment member 1.

[0098] After the line body S is placed on the length adjustment member 1, the line body S is set to the desired length. Then, the position on the upper surface of the cover member 20 where the locking member 22 is located is pressed in from the upper side to the lower side in the vertical direction, thereby causing the cover member 20 to... Figure 13 The locked position shown has been moved.

[0099] The locking member 22 is provided with at least one first locking portion 22a protruding from the second rod 16 toward the first rod 15. The front end of the first locking portion 22a is longer than the end 21A of the cover member body 21 constituting the upper surface portion of the cover member 20 in the front-rear direction (see reference). Figure 10 ) protrudes in the direction of the first rod 15 (refer to) Figure 9 On the other hand, the first rod 15 has a stepped engagement portion 12 opposite to the first locking portion 22a. As such, when the cover member 20 is pressed in from the upper side to the lower side in the vertical direction, the first locking portion 22a descends along the side of the first rod 15 and engages with the engagement portion 12 provided on the side of the first rod 15, thereby completing the movement of the cover member 20 to the locked position.

[0100] When the cover component 20 moves to the locked position, such as Figure 13 As shown, the first rod side line body S1 is clamped by the engagement of the stepped portion of the engaging portion 12 and the first locking portion 22a, thus preventing it from moving. In this way, the first rod side line body S1 becomes a locking mechanism based on engagement, so the line body S is locked in a bent state between the first locking portion 22a and the stepped portion of the engaging portion 12. This has the advantage of being locked under conditions of increased frictional resistance. In addition, it also has the advantage of producing a locking sensation when the cover member 20 is closed.

[0101] In addition, such as Figure 13As shown, the second rod side member S2 is clamped by the second rod 16 and the second locking part 22b, and therefore cannot move. In this embodiment, the second rod side member S2 is clamped by the frictional force generated between its surface and the surface of the second rod 16, and by the frictional force generated between its surface and the surface of the second locking part 22b. While the first rod side member S1 is a locking mechanism based on engagement, the second rod side member S2 is clamped by frictional force, not engagement. Therefore, when the cover member 20 is opened, the cover member 20 does not interfere with the second rod 16, thus providing a favorable operational feel during unlocking. Furthermore, from the perspective of operational feel during unlocking, it is more preferable to pre-set the surface of the second locking part 22b opposite to the surface of the second rod 16 to be recessed in the direction from the second rod 16 toward the first rod 15 by making a larger chamfer. If configured in this way, the cover component 20 will not only not interfere with the second rod 16, but will also be less likely to interfere with the line body S, thus making the operation feel better when releasing it.

[0102] In addition, from Figure 10 The angle formed by the vertical line connecting the front-rear end face 21A of the cover member body 21 to the front end of the first locking part 22a is an obtuse angle or a right angle. Therefore, the surface of the line body is less susceptible to scratches or other damage when locked. In addition, the front end of the first locking part 22a has a rounded corner, and the surface of the first rod 15 opposite to the front-rear end face 21A of the cover member body 21 is an inclined surface, so the surface of the line body is also less susceptible to scratches or other damage during locking operation.

[0103] (How to unlock line body S)

[0104] The method for unlocking the line body S is explained. Regarding the unlocking method, by pressing the operating tab 25 from the upper side to the lower side in the vertical direction, the first locking part 22a is disengaged from the engaged part 12, and the cover member 20 is moved to the unlocked position.

[0105] Furthermore, regarding the method of unlocking, it is sufficient to apply force in the direction in which the first locking part 22a disengages from the engaging part 12; therefore, it is not limited to the method of operating the operating tab 25. For example, it is also possible to pinch the left and right side of the cover member 20 with fingers and pull it up in the opening direction, or as... Figure 13 As shown, by forcefully and impactfully pulling the front-end portion S1a of the first locking part 22a of the first rod side member when locked and / or the front-end portion S2a of the second locking part 22b of the second rod side member when locked, the cover member 20 can be moved to the unlocked position. Furthermore, the cover member 20 is configured to be able to... Figure 3 The locked state shown Figure 4 The state shown is approximately rotated 90 degrees. That is, in Figure 4 Before the state shown, the cover member 20 will not interfere with the main body member 10 and thus will not hinder rotation; only when it becomes Figure 4 After reaching this state, the main component 10 interferes with the position, thus hindering the rotation of the cover component 20. Furthermore, to allow the line body S to pass easily, the cover component 20 is positioned from... Figure 3 The locked state shown Figure 4 The state shown is rotated within a range of 80 degrees or less (preferably around 80 degrees, considering the ease of passage of the lines).

[0106] When the cover component 20 moves to the unlocked position, such as Figure 14 As shown, the first rod side line body S1 and the second rod side line body S2 are separated from the locking member 22, and therefore can move freely.

[0107] <Second Implementation Method>

[0108] Reference Figure 15 and Figure 16 The second embodiment of the present invention will be described below.

[0109] The main difference between the length adjustment member 1 in the second embodiment and that in the first embodiment is: Figure 15 As shown, the width of the length adjusting member 1 in the left-right direction is approximately twice the width of the length adjusting member in the left-right direction in the first embodiment; a third rod 18 extending along the entire front-rear direction is provided at the center position of the main body member 10 in the left-right direction; as shown Figure 16 As shown, a locking member 22 is provided that spans the third rod 18; and a notch 22c for the third rod 18 to enter is provided at the center position in the left-right direction of the locking member 22.

[0110] Furthermore, descriptions of structures that are the same as or identical to those in the first embodiment are omitted.

[0111] like Figure 15 and Figure 16 As shown, the main body 11 of the main component forms six holes by means of the first rod 15, the second rod 16 and the third rod 18: a first through hole H11, another first through hole H12, a second through hole H21, another second through hole H22, a third through hole (not shown) and another third through hole (not shown).

[0112] like Figure 16 As shown, the locking member 22 is configured to have a first locking part 22a1, another first locking part 22a2, a second locking part 22b1, and another second locking part 22b2 by providing a notch 22c. Figure 15The locking position shown is such that two first rod side lines S1 are clamped by a first locking part 22a1 and another first locking part 22a2 and the first rod 15 of the main body member 10, and two second rod side lines S2 are clamped by a second locking part 22b1 and another second locking part 22b2 and the second rod 16 of the main body member 10.

[0113] In addition, such as Figure 16 As shown, a first locking part 22a1 and a second locking part 22b1 are formed to approximately half the width of a first through hole H11 in the left-right direction. Therefore, when unlocking, the side without the locking member 22 can be used when the second rod side liner S2 passes through the second rod 16. That is, when unlocking, if the gap formed between the cover member 20 and the second rod 16 is small, it may be difficult for the front end of the second rod side liner S2 to pass through the second rod 16 (especially when the front end of the shoelace passes through), but even in such cases, the front end of the second rod side liner S2 can pass through.

[0114] The other first locking part 22a2 and the other second locking part 22b2 have the same structure, so the description is omitted.

[0115] (How to lock the line body S)

[0116] The method of using the length adjustment member 1 in the second embodiment, especially the method of locking the line body S, is basically the same as in the first embodiment, but the way the line body S passes is different from that in the first embodiment. Therefore, this point will be explained in the following.

[0117] First, by pressing the operating tab 25 from the upper side to the lower side in the vertical direction, the cover member 20 is moved towards... Figure 16 Move to the unlocked position as shown.

[0118] Then, when the line body S is first set on the length adjustment member 1, the first rod side line body S1 and the second rod side line body S2 are passed through the length adjustment member 1.

[0119] Specifically, the first rod side line body S1 passes from the lower side to the upper side of another first through hole H12 in the vertical direction, and then passes from the upper side to the lower side of another second through hole H22 via the upper surface of the first rod 15.

[0120] Furthermore, based on having a certain amount of leeway for the first rod side line body S1 (based on forming a loop), the first rod side line body S1 is folded back.

[0121] Then, the first rod side line body S1 passes through the lower side of the second through hole H21 in the vertical direction towards the upper side, and then passes through the upper surface of the first rod 15 through the upper side of the first through hole H11 in the vertical direction towards the lower side.

[0122] In addition, an example is given in which the first rod side line body S1 passes through another first through hole H12 first, but it is also possible to pass through a first through hole H11 first.

[0123] The second side line S2 passes through the same path as the first side line S1, so the description is omitted.

[0124] As described above, in the length adjustment member 1 of the second embodiment, the first rod side line body S1 and the second rod side line body S2 pass through with a certain degree of margin (based on forming a loop), so the length of the line body S can also be adjusted according to the degree of margin.

[0125] <Third Implementation Method>

[0126] Reference Figures 17 to 20 The third embodiment of the present invention will be described below.

[0127] The main difference between the length adjustment member 1 in the third embodiment and that in the first embodiment is: Figure 17 As shown, the main body member 10 has a main body notch 19a for receiving the cover member 30 at the center position in the front-rear direction; as Figure 19 and Figure 20 As shown, the second locking part 32b of the locking member 32 is shaped to protrude toward the second rod 16; the two ends of the length adjusting member 1 in the left and right directions are not flush (the amount of protrusion to the left and right directions corresponds to the thickness of the drooping part 33); in the locked position, the upper surface of the length adjusting member 1 is not flush; and a shaft part 34 is provided on the cover member 30 side, and a bearing part (not shown) is provided on the main body member 10 side.

[0128] Furthermore, descriptions of structures that are the same as or identical to those in the first embodiment are omitted.

[0129] In the third embodiment, such as Figure 19 and Figure 20 As shown, the second locking portion 32b of the locking member 32 is shaped to protrude toward the second rod 16, thus making the distance from the shaft portion 34 of the cover member 30 to the second locking portion 32b shorter than the distance from the shaft portion 13 to the second locking portion 22b in the first embodiment.

[0130] According to this structure, in the third embodiment, not only during locking, but also during unlocking, such as Figure 20 As shown, the second rod side line body S2 is also clamped by the second rod 16 and the second locking part 32b.

[0131] Therefore, in the third embodiment, the second rod side line body S2 will not move regardless of the position of the cover member 30. Therefore, there is no need to worry about the movement of the second rod side line body S2. The length of the line body S can be adjusted by operating the cover member 30 and the first rod side line body S1 with one hand.

[0132] Furthermore, in the third embodiment, since the distance from the shaft portion 34 of the cover member 30 to the second locking portion 32b is relatively short, when the cover member 30 is moved to the locking position, the central position of the cover member 30 in the front-rear direction may interfere with the central position of the main body member 10.

[0133] However, in the third embodiment, since it has a main body notch 19a, therefore... Figure 17 As shown, this can prevent interference between the two.

[0134] Although not illustrated, in the third embodiment, the main body member 11 may be formed with six holes, namely a first through hole H11, another first through hole H12, a second through hole H21, another second through hole H22, a third through hole, and another third through hole, using the first rod 15, the second rod 16, and the third rod 18, just as in the second embodiment.

[0135] In this configuration, it is preferable to provide a locking member notch for the third rod 18 to enter at the center position in the left-right direction of the locking member 32, as in the second embodiment.

[0136] <Fourth Implementation>

[0137] Reference Figures 21 to 26 The fourth embodiment of the present invention will be described below.

[0138] The main difference between the length adjustment member 1 in the fourth embodiment and that in the first embodiment is: Figure 25 As shown, the main body member 10 has a groove 19b at its center in the front-rear direction for receiving a guide protrusion (not shown) provided on the cover member 40; as Figure 24 As shown, the vertical height of the second rod 16 is the same as the height of the first rod 15; and as shown... Figures 23 to 26 As shown, the cover component 40 moves relative to the main component 10 in the vertical direction.

[0139] Furthermore, descriptions of structures that are the same as or identical to those in the first embodiment are omitted.

[0140] In the fourth embodiment, such as Figure 25As shown, the drooping portion 43 of the cover member 40 has a guide protrusion (not shown) that is guided by the groove 19b provided in the main body member 10, so the cover member 40 can move in the vertical direction relative to the main body member 10.

[0141] In addition, a limiting member (not shown) is provided near the upper end of the groove 19b to limit the guide protrusion of the drooping part 43, so that the cover member 40 will not come off the main body member 10.

[0142] like Figure 24 and Figure 26 As shown, the locking member 42 has a first locking part 42a, a second locking part 42b, a third locking part 42c, and a fourth locking part 42d.

[0143] When the cover component 40 moves Figure 24 When in the locked position shown, the first rod side line S1 and the second rod side line S2 are clamped by the first rod 15, the second rod 16, the first locking part 42a, and the second locking part 42b, and therefore cannot move.

[0144] In addition, since the cover member 40 has a third locking part 42c and a fourth locking part 42d, it is possible to prevent the cover member 40 from being pressed down excessively and thus releasing the clamped state of the line body S.

[0145] Because of the structure described above, the present invention can provide a length adjustment member for a linear body that, compared with conventional length adjustment members for linear bodies, requires less time to adjust the length of shoelaces and has a locking / unlocking function at any position desired by the user.

[0146] The application of the length adjustment component of this invention is not particularly limited; for example, it can be used in safety shoes, children's shoes, sports shoes, high-top shoes, etc. Furthermore, it is not limited to shoes; it can also be used in shoulder straps of bags, camera straps, waistbands of clothing, etc.

[0147] Furthermore, the present invention is not limited to the above-described embodiments. It is also possible to make appropriate use of technologies that are substantially the same as or have the same effect as the technical matters described in the embodiments of the present invention, which can be recognized by those skilled in the art, or to use them as alternative technologies or to add them in an additional form.

[0148] For example, as a variation, in the above implementation, such as Figure 9 As shown, a locking member 22 is provided only on one side of the cover member 20 in the left-right direction, and no locking member 22 is provided on the other side so that the notch 14 for the line body to pass through can be exposed. However, it can also be done as shown. Figure 27 , Figure 28As shown, a pair of locking members 22-1 and 22-2 are provided at the ends of both sides of the cover member 20 in the left-right direction, and a notch 14 for the passage of the line body is arranged at a position corresponding to the pair of locking members 22-1 and 22-2. In this case, Figure 6 The notch 14 shown is located at the center of the third through hole H3 in the left-right direction.

[0149] Furthermore, as another variation, when the length adjustment member 1 is used as an adjustment member for shoelaces, it can also be used by inverting the back of the length adjustment member 1 (inverting the back in the vertical direction). If used upside down, it is blocked by the foot, and has the advantages of locking the cover member 20 so that it is not easy to accidentally fall off.

[0150] Furthermore, if we focus only on a portion of the length adjustment member 1 in this embodiment, it can also be considered as another invention. Specifically, the adjusting buckle (Japanese: コキ) member, which constitutes part of the length adjustment member 1, can be said to possess a novel structure not previously seen. More specifically, refer to... Figure 6 Please provide an explanation. Figure 6 The main component 10 of the described length adjustment member 1 is configured as an adjustment buckle member, which serves as the length adjustment component of the line body S2, by utilizing the first through hole H1, the third through hole H3, and the second rod 16 disposed between the first through hole H1 and the third through hole H3. In particular, this adjustment buckle member is particularly advantageous when used for adjusting the length of shoelaces, which are widely used as shoelaces and have a rod-shaped fixing part (a rod-shaped fixing part provided for passing through the shoelace through hole) at the front end. If described as an inventive concept, it becomes "an adjustment buckle member, which is an adjustment buckle used for flat ropes, having two or more through holes (the first through hole H1 and the third through hole H3 in the above embodiment), wherein the through hole has a length corresponding to the width direction of the flat rope when the flat rope passes through as the long side and a length corresponding to the thickness direction of the flat rope as the short side, wherein one or more through holes (the third through hole H3 in the above embodiment) have two or more different short side lengths in the long side direction." Therefore, even when the adjusting buckle is miniaturized, it can pass through not only flat ropes but also the rod-shaped fixing part at the front end of the flat rope.
