Description
Technical Field
The present invention relates to a rope fastener which is engaged with a rope to be passed through.
Background
Conventionally, for example, a string fastener described in patent document 1 below is used to fix a string to a proper length in clothing with a hood, sports shoes, and the like. The string fastening member is provided in the upper and lower through-holes through which the string is passed. The rope fastener is a part formed by embedding the socket and the plug, and the rope passes through each hole. The socket rotates about the bore relative to the plug. When the socket is rotated, the hole is eccentric and the cord bends in the hole. The relative movement of the bent cord and the cord fastener is restricted. Thus, for example, the string of the hood is fixed by the string fastener in an appropriate length, whereby the hood maintains a tightened state.

Problems to be solved by the invention
According to the above-described cord fastener, the operation of changing the position of the cord fastener is an operation of moving the cord fastener along the cord or pulling the cord with respect to the cord fastener, and on the other hand, the operation of fixing the cord fastener to the cord is an operation of rotating the socket with respect to the plug. Therefore, the two operations are different and sometimes difficult to operate.
The present invention has been made in view of such circumstances. That is, an object of the present invention is to provide a rope fastener which can be operated easily, conceptually and consistently.
Means for solving the problems
In order to achieve the above object, a rope fastener according to the present invention includes: a pair of sliders through which the string passes and arranged in a longitudinal direction of the string; and a housing that houses the pair of sliders, the pair of sliders being freely displaceable relative to the rope in a state in which the pair of sliders are separated from each other, and the rope being locked between the pair of sliders in a state in which the pair of sliders are close to each other.
The string fastener of the present invention is characterized in that the string is an elastic string that can be stretched in the longitudinal direction. In this case, the rope fastener is characterized by comprising: a pair of sliders through which an elastic string passes and which are arranged in a longitudinal direction of the string; and a housing that houses the pair of sliders, wherein the pair of sliders are configured to be displaced relative to the rope in a state in which the pair of sliders are separated from each other, and the pair of sliders approach each other when the elongated rope is contracted, and the rope is locked between the pair of sliders.
In the cord fastener of the present invention, the pair of sliders have protrusions protruding toward the cord, and the protrusions face each other in a state where the pair of sliders are close to each other.
In the rope fastener according to the present invention, the slider is moved by the protrusion of one of the sliders being hooked on the contracted rope.
The rope fastener of the present invention is characterized in that the pair of sliders are separated from each other by the housing pressing one of the sliders along the rope in a state where the pair of sliders are close to each other.
The rope fastener of the present invention is characterized in that the inner surface of the housing has an inner guide portion along the longitudinal direction of the rope, and the outer surfaces of the pair of sliders have outer guide portions fitted to the inner guide portion.
The rope fastener of the present invention is characterized in that the pair of sliders includes: an outer retaining portion that is locked to an end portion of the housing from outside the housing; and an inner retaining portion locked to an end of the housing from inside.
In the rope fastener of the present invention, the housing is cylindrical, the pair of sliders are cylindrical and have the same shape as each other, and each slider has: a main body portion disposed inside the housing, and having tubular axial distal end portions formed at different heights; and a head portion connected to the opposite side of the distal end portion, disposed outside the end portion of the housing, and having a larger diameter than the body portion.
Effects of the invention
The rope fastener of the present invention has a pair of sliders through which a rope is passed and arranged in a longitudinal direction of the rope, and a housing in which the pair of sliders are housed, wherein the pair of sliders are freely displaced relative to the rope in a state of being separated from each other, and the rope is locked between the pair of sliders in a state of being brought close to each other. That is, the operation of changing the position of the rope fastener is an operation of moving the rope fastener along the rope or pulling the rope with respect to the rope fastener, and on the other hand, the operation of fixing the rope fastener to the rope is an operation of releasing the rope from an external force. Therefore, simple, convenient, simple-to-concept and consistent operation is realized. The cord is an elastic cord that can be stretched in the longitudinal direction, and the cord fastener of the present invention includes: a pair of sliders through which an elastic string passes and which are arranged in a longitudinal direction of the string; and a housing that houses the pair of sliders, the pair of sliders being freely displaceable relative to the cord in a state of being separated from each other, and the operation of fixing the cord fastener to the cord is an operation of releasing the extended cord from an external force in a configuration in which the pair of sliders are brought close to each other by contraction of the extended cord and the cord is locked between the pair of sliders. When the rope is contracted, one slider follows the rope and automatically approaches the other slider, and the rope is locked between the sliders.
The pair of sliders of the rope fastener of the present invention have protrusions protruding toward the rope, and the protrusions face each other in a state where the pair of sliders are close to each other. According to this configuration, the pair of sliders approach each other, and the protrusions face each other to sandwich the string. In other words, in a state where the pair of sliders are separated from each other, the protrusions are displaced from each other in the longitudinal direction of the rope, and therefore the rope passes through the gaps between the protrusions. That is, the rope fastener is changed between a state of being locked to the rope and a state of being able to change its position with respect to the rope by moving the pair of sliders in the longitudinal direction of the rope. Therefore, simple, convenient, simple-to-concept and consistent operation is realized.
The rope fastener of the present invention is hooked to the contracted rope by the protruding portion of one slider, and the slider moves. That is, when the rope is contracted, the protrusion of one slider is hooked on the contracted rope, and thereby the slider approaches the other slider, and the rope is locked between the sliders. Therefore, the operation of fixing the string fastening member to the string is achieved by utilizing the contraction of the string.
In the string fastener of the present invention, in a state where the pair of sliders are close to each other, the housing presses one slider along the string, whereby the pair of sliders are separated from each other. The cord fasteners are free to move along the cords by the sliders being separated from each other. That is, the operation of releasing the string held by the slider is an operation of moving the slider along the string, which is continuous with an operation of moving the string fastener along the string (or pulling the string with respect to the string fastener) to change the position of the string fastener. Therefore, simple, convenient, simple-to-concept and consistent operation is realized.
The rope fastener of the present invention has an inner guide portion along the longitudinal direction of the rope on the inner surface of the housing, and an outer guide portion fitted to the inner guide portion on the outer surfaces of the pair of sliders. That is, the housing and the slider are guided to be linearly displaced by interposing the inner guide portion and the outer guide portion therebetween.
The pair of sliders of the rope fastener of the present invention includes: an outer anti-drop part clamped on the end of the shell from the outer side of the shell; and an inner retaining portion locked to an end of the housing from the inside. That is, the slider does not come off from the housing but moves relative to the housing within the range of each retaining portion, in other words, the housing does not come off from the slider but moves relative to the slider within the range of each retaining portion. Therefore, a simple operation can be realized.
The rope fastener of the present invention has a cylindrical housing, a pair of sliders having the same shape as each other, each slider having: a main body portion disposed inside the housing and having tubular axial front end portions formed at different heights; and a head portion connected to the opposite side of the distal end portion, disposed outside the end portion of the case, and having a larger diameter than the body portion. The rope fastener is constituted by three members of a housing and a pair of sliders, and since the respective sliders have the same structure, it is simple and convenient to constitute the rope fastener by two members of the housing and the sliders.

Detailed Description
Hereinafter, a rope fastener according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1(a), (b), (c), and (d) show the external appearance of the rope fastener 10 according to the embodiment of the present invention, and fig. 2(a) and (b) show the external appearance of the rope fastener 10 after disassembly.
As shown in fig. 1(a), (b), (c), and (d), the string fastening piece 10 is cylindrical, and a hole 11 is formed to penetrate through the center of the cylindrical shape in the longitudinal direction. The hole 11 is penetrated by the elastic cord 1 (see fig. 5 (a)). The rope 1 is, for example, a rubber rope or the like woven from a natural rubber thread, a synthetic rubber thread or the like. Hereinafter, the longitudinal direction of the tube (or the cord 1) is referred to as the top-bottom direction, and the direction perpendicular to the top-bottom direction is referred to as the front-back, left-right direction.
As shown in fig. 2(a) and (b), the rope fastener 10 is composed of three members. That is, the string fastening piece 10 has a case 12 housing a pair of sliders 16 and 17, and a first slider 16 and a second slider 17 housed in the case 12.
Here, the components 12, 16, and 17 will be described in detail based on the drawings. Fig. 3(a), (b), (c), (d), and (e) show the appearance and cross section of the housing 12, and fig. 4(a), (b), (c), and (d) show the appearance of the first slider 16. Since the sliders 16 and 17 have the same shape, only one first slider 16 will be described below, and the same reference numerals as those of the first slider 16 will be shown, and the description of the second slider 17 having the same structure will be omitted.
As shown in fig. 3(a), (b), (c), (d), and (e), the housing 12 is cylindrical. That is, the housing 12 has a vertically penetrating receiving hole 13 formed therein, and has open upper and lower ends. A pair of inner guide portions 14a and 14b facing each other are formed on the inner surface of the housing 12. The inner guide portions 14a and 14b are grooves formed on the inner surface of the housing 12, and extend linearly upward and downward from the upper end to the lower end. The lower end of the inner guide portion 14a on the front side (left side in fig. 3 b) is open, and the upper end of the inner guide portion 14a, that is, the upper end portion of the case 12 is closed and has a terminal end portion 15 a. Similarly, the rear side (the right side in fig. 3 b) of the inner guide portion 14b has an open upper end, and the lower end of the inner guide portion 14b and the lower end of the housing 12 are closed to have a terminal portion 15 b. The terminal portions 15a and 15b are not grooves, but protrude toward the receiving hole 13 than the inner guides 14a and 14 b.
As shown in fig. 4(a), (b), (c), and (d), the first slider 16 is substantially cylindrical. That is, the first slider 16 has a string passage hole 18a formed therethrough in the vertical direction, and has an open upper and lower end portion. The first slider 16 includes an annular head portion 19a and a substantially cylindrical body portion 21a connected to a lower portion of the head portion 19 a. The head portion 19a is formed to have a larger diameter than the body portion 21a, and is formed with an outer retaining portion 20a protruding outward from the body portion 21 a. The cylindrical axial front end portions of the body portion 21a are formed to have different heights. That is, the front side (left side in fig. 4 b) of the body 21a is a long cylindrical piece 22a formed to be long downward, and the rear side (right side in fig. 4 b) is a short cylindrical piece 23a formed to be shorter than the long cylindrical piece 22 a. The long cylindrical piece 22a has an outer guide portion 24a formed on the outer surface. The outer guide portion 24a is a protrusion and extends linearly upward and downward from the head portion 19a to the front end portion. The long cylindrical piece 22a has a protrusion 25a formed on an inner surface thereof and protruding toward the cord passage hole 18 a. The protrusion 25a is formed in a mountain shape connecting the two inclined surfaces. That is, the projection 25a is formed of a first inclined surface portion 26a inclined toward the cord passage hole 18a as going upward from the tip end portion, and a second inclined surface portion 27a connected to the top of the first inclined surface portion 26a and inclined toward the long cylindrical piece 22a as going upward. On the other hand, the short tube piece 23a has an inner retaining portion 28a formed on the outer surface of the distal end portion. The inner retaining portion 28a is a protrusion.
As described above, the respective units 12, 16, and 17 are configured. Here, the state and operation of the assembled parts 12, 16, and 17 will be described based on the drawings. Fig. 5(a), (b), and (c) are cross-sections of the string fastener 10, showing the operating state.
As shown in fig. 5(a), (b), and (c), the first slider 16 is inserted into the housing hole 13 from the upper end side of the housing 12 and is disposed inside the housing 12. At this time, the outer guide portion 24a of the first slider 16 is fitted to the inner guide portion 14b of the housing 12, and the inner retaining portion 28a of the first slider 16 is fitted to the inner guide portion 14a over the terminal end portion 15a of the inner guide portion 14 a. The outer guide portion 24a is guided along the inner guide portion 14b, and the inner retaining portion 28a is guided along the inner guide portion 14a, whereby the first slider 16 is linearly guided vertically with respect to the housing 12. The outer retaining portion 20a of the first slider 16 is engaged with the upper end portion of the housing 12 from the outside, and the inner retaining portion 28a is engaged with the terminal end portion 15a of the housing 12 from the inside. That is, by disposing the terminal end portion 15a of the housing 12 between the outer retaining portion 20a and the inner retaining portion 28a of the first slider 16, the housing 12 and the first slider 16 can move relatively freely within the range between the retaining portions 20a, 28 a.
Similarly, the second slider 17 is inserted into the housing hole 13 from the lower end side of the housing 12 and is disposed inside the housing 12. The outer guide portion 24b of the second slider 17 is fitted to the inner guide portion 14a of the housing 12, and the inner retaining portion 28b of the second slider 17 is fitted to the inner guide portion 14b over the terminal end portion 15b of the inner guide portion 14 b. The housing 12 and the second slider 17 are relatively movable in the range between the retaining portions 20b, 28 b.
The long cylinder piece 22a of the first slider 16 and the short cylinder piece 23b of the second slider 17 face each other in the vertical direction, and are fitted into the same inner guide portion 14 b. Similarly, the short cylindrical piece 23a of the first slider 16 and the long and short cylindrical piece 22b of the second slider 17 face each other in the vertical direction, and are fitted into the same inner guide portion 14 a.
When the cord 1 passes through the cord flow passages 18a, 18b of the respective sliders 16, 17, the respective sliders 16, 17 are aligned in the longitudinal direction of the cord 1. The protrusions 25a and 25b of the sliders 16 and 17 protrude toward the string 1, but in a state where the sliders 16 and 17 are separated from each other, the string 1 passes through a gap generated between the protrusions 25a and 25b, and thus the string fastening piece 10 and the string 1 can move relatively freely (see fig. 5 (a)). On the other hand, in a state where the sliders 16 and 17 are close to each other, the protrusions 25a and 25b face each other and bite into the rope 1, and thus the rope fastening piece 10 is locked to the rope 1 (see fig. 5 (b)).
Further, the string 1 may be inserted into the string fastening device 10 after the respective units 12, 16, and 17 are assembled, or the respective units 12, 16, and 17 may be assembled in a state where the string 1 is inserted into the second slider 17, the housing 12, and the first slider 16 in advance.
The rope fastener 10 assembled as described above performs the following operations. In the following, a case of attaching the string fastener 10 to the string 1 of the hood in a garment (not shown) will be described on the premise. The eyelet 2 in fig. 5(a), (b), (c) is mounted in a hole of a hood through which the string 1 passes.
Fig. 5(a) shows a state in which the sliders 16 and 17 are separated from each other, and the string 1 and the string fastening piece 10 are freely movable relative to each other (hereinafter, referred to as "adjustment state"). In the adjustment state, since the sliders 16 and 17 are separated in the vertical direction, the protrusions 25a and 25b of the sliders 16 and 17 are also separated from each other, and a gap of a degree that the cord 1 passes is generated between the protrusions 25a and 25 b. Since the case 12 and the sliders 16 and 17 are relatively movable with respect to each other, when the user grips the case 12 and raises it with respect to the rope 1, the case 12 moves with respect to the sliders 16 and 17 in a state where the sliders 16 and 17 are separated from each other. Further, when the housing 12 is raised and the terminal end portion 15a of the housing 12 is locked to the outer retaining portion 20a of the first slider 16, the first slider 16 is pulled up together with the housing 12 and raised. At the same time, the inner retaining portion 28b of the second slider 17 is locked to the terminal end portion 15b of the housing 12, and the second slider 17 is also pulled up together with the housing 12 and raised. Further, when the housing 12 is lowered, the housing 12 moves relative to the sliders 16 and 17 in a state where the sliders 16 and 17 are separated from each other, and the sliders 16 and 17 are also pulled down as in the case of being raised. When the string 1 is pulled with respect to the string fastening piece 10, the same operation as described above is performed.
In the adjusted state, when the rope 1 is pulled downward with respect to the rope fastener 10 in a state where the head portion 19a of the first slider 16 is in contact with the eyelet 2, the rope 1 is extended by an upward frictional force generated by friction with the eyelet 2 and an external force pulling downward.
Fig. 5(b) shows a state in which the sliders 16 and 17 are close to each other, and the string 1 is locked between the sliders 16 and 17 (hereinafter, referred to as "locked state"). When the rope 1 is released from the downward external force, the rope contracts due to the restoring force P, and at this time, the protrusion 25b of the second slider 17 hooks the contracted rope 1, whereby the second slider 17 is pulled up and approaches the first slider 16. When the projections 25a, 25b face each other, the string 1 is locked between the projections 25a, 25b, and therefore the string fastening piece 10 does not move relative to the string 1.
Fig. 5(c) shows a state in which the sliders 16 and 17 are separated from each other by the lowering of the housing 12, and the string 1 is released from the sliders 16 and 17 (i.e., an adjustment state). In the locked state, the terminal end portion 15b of the housing 12 is locked to the outer retaining portion 20b of the second slider 17, and therefore, when the user grips the housing 12 and lowers it with respect to the rope 1, the second slider 17 is also pressed by the housing 12 and lowers it. When the sliders 16 and 17 are separated from each other, the protrusions 25a and 25b of the sliders 16 and 17 are also separated from each other, and a gap is generated between the protrusions 25a and 25b, so that the adjustment state is achieved.
The rope fastener 10 acts as described above. Next, the effect of the cord fastener 10 will be described.
In the adjustment state in which the sliders 16 and 17 are separated from each other, the string 1 passes through a gap generated between the protrusions 25a and 25b, and thus the string fastening piece 10 and the string 1 can move relatively freely (see fig. 5 (a)). When the rope 1 is pulled and the downward external force is released, the rope contracts due to the restoring force P, and at this time, the protrusion 25b of the second slider 17 hooks the contracted rope 1, whereby the second slider 17 is pulled up (see fig. 5 (b)). When the protrusions 25a and 25b face each other and bite into the rope 1, the rope 1 is locked between the protrusions 25a and 25b, and therefore the rope fastener 10 does not move relative to the rope 1. That is, the operation in the adjustment state is an operation of moving the rope fastener 10 along the rope 1 or pulling the rope 1 with respect to the rope fastener 10, while the operation to the engagement state is an operation of releasing the extended rope 1 from the external force. In any case, the user moves the string fastening member 10 and the string 1 up and down, and thus, a simple, conceptual and consistent operation is achieved.
In the locked state in which the sliders 16 and 17 are close to each other, when the user grips the housing 12 and lowers it with respect to the rope 1, the second slider 17 is also pressed by the housing 12 and lowered. When the sliders 16 and 17 are separated from each other, the protrusions 25a and 25b of the sliders 16 and 17 are also separated from each other, and a gap is generated between the protrusions 25a and 25b, so that the adjustment state is achieved. That is, the operation of releasing the string 1 held between the sliders 16 and 17 is an operation of moving the string fastener 10 along the string 1, and this operation is continued to the operation to the adjustment state. Therefore, simple, convenient, simple-to-concept and consistent operation is realized.
The string fastener 10 has inner guide portions 14a and 14b extending in the vertical direction in parallel with the string 1 on the inner surface of the housing 12, and outer guide portions 24a and 24b fitted to the inner guide portions 14a and 14b on the outer surfaces of the sliders 16 and 17. That is, the housing 12 and the sliders 16 and 17 can be linearly displaced by interposing the guide portions 14a, 14b, 24a, and 24b therebetween.
Each of the sliders 16 and 17 of the rope fastener 10 has: outer retaining portions 20a and 20b locked to the end of the housing 12 from the outside of the housing 12, and inner retaining portions 28a and 28b locked to the end of the housing 12 from the inside. That is, the sliders 16 and 17 are not separated from the housing 12, and are relatively freely movable within the range of the retaining portions 20a, 20b, 28a, and 28 b. Therefore, a simple operation is realized.
The rope fastener 10 is constituted by three members of the housing 12, the first slider 16 and the second slider 17, and since the respective sliders 16, 17 have the same structure, it is simple and convenient to constitute by two members of the housing 12 and the respective sliders 16, 17.
In another embodiment (not shown), the outer guide portion is not linear but a plurality of projections arranged in the vertical direction or a single projection. In another embodiment (not shown), the inner guide is a protrusion, and the outer guide is a groove fitted with the inner guide. The external force for extending the string 1 is not limited to the frictional force generated by the eyelet 2 as long as the external force is an external force in a direction opposite to the force pulled by the user and is intended to fix the string 1. In another embodiment (not shown), a non-stretchable cord is used.
The embodiments of the present invention have been described above in detail, but the present invention is not limited to the above embodiments. The present invention can be modified in various ways without departing from the scope of the present invention. For example, the present invention mounts a string that passes through a hood, sleeve, waist, hem, shoe, etc. of clothes, a string that passes through a mouth of a bag, backpack, etc. of a bag, etc.
