In the above-described rope fixing device, the number of the members is small, and the ropes that are placed on the clothes or the bag body are locked by the through holes, and the amount of the ropes can be easily adjusted, which is simple and convenient to use. Good, but there are still some shortcomings based on the following points.

(1) In the use state of Fig. 6(a), etc., the amount of pulling out of the rope W is increased to enhance the degree of pulling out, and the operator operates by one hand (finger) to make the female member 1 and the male The type member 2 is relatively close to the spring force, or the holding member 2 is pressed against the female member 1 to release the state of preventing the falling off of the rope W, while maintaining the state, the other hand is The pull-out end side of the rope W is pulled out and adjusted. Thereafter, when the hand is separated from the female member or the female/male member, the female/male members 1, 2 are moved in a direction in which the elastic force is moved away from each other to prevent the rope from coming off. Therefore, in the conventional structure, it is necessary to have a force proportional to the magnitude of the projectile thrust in the adjustment operation, and it is difficult to perform the pull-out adjustment of the rope when the hand holds the article or performs other work, for example. , becoming the main cause of limited use.

(2) Although the cord fixing device is used in a state in which the belt W' is attached to the object M to be used, the portion bound by the strap W' is the lower end side of the cord fixing member (in other words, by being disposed on the female member 2) The through hole 16 of the end portion is unstable, and for example, the degree of shaking is likely to increase when subjected to vibration. As described above, there is also a case where the cord fixing device becomes large due to the use, and this kind of situation is liable to cause a problem and becomes a main cause of low quality.

The object of the present invention is to solve the above problems, and in particular to reduce the force at the time of adjusting the amount of pulling out of the rope, and to maintain a stable mounting state for the object to be used, thereby contributing to the improvement of reliability and expansion. use.

In order to achieve the above object, a rope fixing device according to the present invention includes a female member having a through hole for a rope, and a male member having a through hole for a rope and slidably inserted into the female member. The female/male member is inserted into the through holes in a state in which the female/male members are relatively close to each other in response to the elastic thrust, and the female/male members are moved in a direction away from each other by the elastic thrust, and become a rope prevention In the detached state, the female member and the male member each have a through hole provided in common with the through hole and through which the tape passes, and the tape is sequentially inserted into each of the female/male members. When the hole is pulled out from the both end sides (this is the use example of FIG. 3), or the above-mentioned tapes are sequentially inserted into the respective through holes of the female/male member to press the both end sides thereof. In the state, when the pull-out portion of the rope that has passed through the through holes is pulled out (this is a use example of Fig. 2), the female/male member approaches and releases the rope from falling off in response to the spring force.

In the above invention, the "rope" includes a rope, a cord, a belt, and the like. The "belt" has substantially the same shape as the rope, and includes ropes, threads, and the like other than the belt. "Through hole" and "through hole" are used for convenience, but in terms of functionality, the insertion is the same. The through hole is a hole through which the cable is pulled out, and the through hole is for the tape insertion. Through hole.

The above invention is preferably embodied in the following manner.

(1) The through hole is configured to be offset by a line connecting the through holes to each other (the second item of the patent application).

(2) the female/male member is elastically urged in a direction away from a spring member interposed between the spring member or one of the female/male members, and the through hole system The spring/male member is disposed substantially in line with the spring pushing direction of the spring pushing member or the spring portion (the third item of the patent application).

(3) The through-holes are configured to be disposed at the outer end portions of the parent/male members that do not overlap each other (the fourth item of the patent application).

(4) The tape is a structure in which both end portions which are overlapped by the respective through holes are sewn and fixed to an object to be used such as clothes (the fifth item of the patent application).

The invention of claim 1 is that the female member and the male member respectively have a through hole which is provided in common with the through hole and through which the tape passes, and the tape is sequentially inserted into the female/public as shown in FIG. Each of the through holes of the type member is pulled out at both end sides thereof, or as shown in FIG. 2, the tape is sequentially inserted into each of the through holes of the female/male member to press the both end sides thereof. When the pull-out portion of the rope that has passed through each of the through holes is pulled out, since the female/male member approaches and releases the rope to prevent the rope from coming off, the rope can be adjusted with a small force. It can also be operated with one hand, thereby improving the convenience of use. Further, in the case where the object to be used is attached through the belt, the whole of the rope fixing device, that is, the female member and the male member are tied by a common belt, so that the stability in the mounted state is good even if subjected to Large vibrations are also difficult to shake, and can eliminate the main cause of low quality.

According to the invention of claim 2, since each of the through holes is provided offset from the line connecting the through holes, there is no rope and the belt inserted into each of the through holes interferes with the pulling amount adjustment operation of the rope. The operability is impaired, thereby facilitating the usability.

According to the invention of claim 3, since the through holes are provided in the female/male member in substantially the same line as the spring pushing direction of the spring pushing member or the spring portion, it is easy to shorten the overall size of the rope fixing device. This can increase the degree of freedom in design.

According to the invention of claim 4, since the through holes are located at the ends of the side where the female and male members do not overlap each other, it is inferred from Fig. 2 that the pulling force in the direction of the arrow of the rope is taken as The female/male members are efficiently transmitted in the direction in which they are close to each other, whereby the operability of the rope pulling amount adjustment can be improved.

According to the invention of claim 5, since the both ends of the belt which are overlapped by the through holes are sewn and fixed to the object to be used, the sewing operation can be surely improved by the sewing operation similar to the conventional one. The operability of the quantity adjustment.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this description, the structure, the action, and the modification of Fig. 5 will be described in detail.

The rope fixing fixture 4 of the (structure) type is composed of a female member 1 and a male member 2 that are fitted to each other, and a spring pushing member 3 interposed between the female/male members 1 and 2. Both the female member 1 and the male member 2 are formed of a resin molded article, but may be other materials. The size is arbitrary and is set according to the object to be used. Further, in FIGS. 3 and 4, the cord fixing tool 4 (the female member 1 and the male member 2) has a symmetrical shape on the front surface and the back surface, and on the right side surface and the left side surface, respectively.

In addition, as shown in FIG. 1 and FIG. 5, the female member 1 has a rectangular flat shape as a whole, and the inner portion 10 is a concave cavity that is formed by the inner end portion 1a toward the outer end portion 1b. The inner 10 series has a shape in which the male member 2 can be inserted, and a pair of curved positioning piece portions 11 are protruded from the central portion of the bottom surface. The positioning piece portion 11 is configured to position one end of the coil spring belonging to the poppet member 3 on the inner side.

In the female member 1, the pair of rope through holes 12 are formed in the inner end portion 1a side in the thickness direction, and the through hole 13 through which the tape 6 passes is formed in the outer end portion 1b in the thickness direction. side. The pair of through holes 12 are substantially circular and are bilaterally symmetrical with respect to the center line. The through holes 13 are substantially rectangular or oblong, and are disposed on the center line.

The male member 2 is formed of a rectangular flat shape which is slightly smaller than the female member 1 and can be slidably inserted into the inner portion 10 of the female member by the inner end portion 2a. In the male member 2, a pair of rope through holes 22 are formed to penetrate the end portion 2a side in the thickness direction, and the through hole 23 through which the tape 6 passes is formed in the thickness direction to form the opposite outer side end portion 2b. side. The pair of through holes 22 have a circular shape substantially the same shape as the through hole 12 on the female member side, and are bilaterally symmetrical with respect to the center line. The through hole 23 is substantially rectangular or oblong in shape substantially the same as the through hole 13 on the female member side, and is provided on the center line.

The male member 2 is provided with a concave portion 20 which is located on the center line and which is notched from the end portion 2a toward the end portion 2b, and a shaft-shaped projection 21 which protrudes from the inner bottom surface of the concave portion 20. The recess 20 is configured to position the other end of the coil spring belonging to the poppet member 3 through the projection 21. On the front and back surfaces of the male member 2, the claw portions 24 are protruded from the end portion 2a side and are located at the edge portions of the respective through holes 22.

Each claw portion 24 is inferred from Fig. 5(c). When the male member 2 is inserted into the inner portion 10 of the female member, it is fitted into the through hole 12 corresponding to the female member with elastic deformation. Thereby, the male member 2 is slidably assembled to the female member 1, and the claw portions 24 abut against the edge of the corresponding through hole 12 without falling off from the female member 1. Further, at the time of the assembly operation, when the male member 2 is inserted into the interior 10 of the female member, the coil spring belonging to the elastic member 3 has one end positioned on the positioning piece portion 11 on the side of the female member, and the other end A projection 21 positioned on the side of the male member.

As shown in FIGS. 2 and 3, the female member 1 and the male member 2 are relatively separated by the elastic thrust of the spring pushing member 3. In the cord anchor 4, the strap 6 is attached to each of the through holes 13 and 23 to have a loop shape. That is, as shown in FIG. 2, the one end portion 6a passes through the through hole 13 from the back surface of the female member 1 toward the front surface, and then passes through the through hole 23 from the front surface of the male member 2 toward the back surface. Alternatively, as shown in FIG. 3, the belt 6 has its one end portion 6a passing through the through hole 13 from the front surface of the female member 1 toward the back surface, and then passes through the through hole 23 toward the front surface from the back surface of the male member 2. Then, the cord fixing device 4 is in a belt-like mounting state of Fig. 1(b) when the both end portions 6a of the strap are pulled out and overlapped on the back side of the cord anchor 4.

However, in the case of a commercially available aspect, the cord fixing device 4 is provided in a state in which the strap 6 has been mounted, and is provided in a state in which the strap 6 is installed in a set, and in a state without a strap. Any of the aspects provided by the purchaser and prepared by the purchaser 6 for installation. Although the shapes of the through holes 13 and 23 and the belt 6 are arbitrary, they are usually designed in accordance with the use object 7 of the rope fixing tool 4. As shown in FIG. 2, the cord fixing device 4 is attached to the object 7 to be used through the belt 6 as needed. Although the mounting method is not technically limited, when the object 7 is used for a clothes or a bag, the method of fixing by sewing is shown as shown in Fig. 2(b), and the appearance or flexibility is used. It is ideal from the point of view. Further, the symbol 8 of Fig. 2(b) shows the sewing portion.

In the cord fixture 4 that is attached to the object 7 by the belt 6 , the rope 5 or the rope 5A disposed on the object 7 is adjusted as shown in Fig. 2 (a) or Fig. 3 (a). The pull-out portion 5a and the degree of fastening are assembled. That is, in the case where the rope 5 or 5a is inserted, the female member 1 and the male member 2 are relatively close to each other against the elastic thrust of the elastic member 3, or the female thrust of the elastic member 3 is resisted. One of the members 1 and 2 is pressed toward the other side, whereby the through holes 12 of the both are overlapped with the through holes 22. In this state, the case of Fig. 2 is a case where the cord 5 is inserted from the back surface of the cord fixture 4 toward the front surface to the one side through holes 12 and 22, and then the front surface is inserted toward the back side to the other side. Holes 12, 22. In the case of Fig. 3, the both ends of the pull-out portion 5a of the cord 5A are inserted into the through holes 12 and 22 on both sides from the back surface of the cord fixture 4 toward the front side. After the insertion, the pressing force of the female/male members 1, 2 is released, or the pressing force of the other member for one of the female/male members 1, 2 is released. In this manner, the female/male members 1, 2 are moved in the relatively separated direction by the elastic thrust of the spring pushing member 3, and the through holes 12, 22 are offset from each other, thereby making the ropes of the rope 5 and the rope 5A correspond to each other. The part is held in the two holes to prevent the rope from falling off.

Next, in the case of the above-described rope fixing tool 4, the amount of pulling and the degree of fastening of the rope 5 are adjusted in the following manner. That is, in the case of the use example of Fig. 2, the operator pulls the pull-out portion 5a of the rope 5 that has passed through each of the through holes 12, 22 to the arrow direction of the second figure (a) with one hand. As shown in Fig. 2(b), since the rope fixing tool 4 is fixed to the fixed position of the object 7 by the above-described belt 6, the pulling force of the drawing portion 5a of the rope 5 passes through the belt 6 and becomes the mother. The stress of the type/male member 1, 2 to the arrow direction of the second figure (b), that is, the stress toward the direction in which the two members 1 and 2 approach each other, the female/male member 1, 2 resists the push As a result of the approaching force of the member 3, the overlapping portions of the respective through holes 12 and 22 are increased, and the state in which the rope is prevented from coming off is released.

Therefore, in this configuration, when the both end portions 6a of the strap are attached to the use object 7 of the clothes or the like, the amount of pulling of the cord 5 can be adjusted by one-hand operation, whereby it can be known. The structure is more convenient to use. Further, in a state in which the transmission belt 8 is attached to the object 7 to be used, the whole of the rope fixture 4, that is, the mother member 1 and the male member 2 are bound by the common belt 6, so that the novelty of the mounting state is It has good stability and is difficult to shake even with large vibrations, and it can eliminate the main cause of low quality compared with the conventional structure.

On the other hand, in the case of the use example of Fig. 3, when the operator pulls the both end portions 6a of the strap 6 in the direction of the arrow with one hand, the cord holder 4 is constructed as shown in Fig. 3(b). As a result of the proximity of the female/male members 1 and 2 against the projectile thrust of the projectile member 3, the portion where the through holes 12 and 22 overlap is increased, and the state in which the rope is prevented from coming off is released. Therefore, even in this use example, when the amount of pulling out of the rope 5A is adjusted, it can be performed with a smaller force than conventionally, and the usability is improved.

Further, in the above configuration, since the through hole 12 of the female member and the through hole 22 of the male member 2 are disposed from the line connecting the through holes 13 and 23 to each other on the line, the rope 5 is provided. In the adjustment operation of the pulling amount of the rope 5A, the rope is not disturbed by the belt 6 inserted into each of the through holes 13 and 23, and the operability or the appearance is deteriorated, whereby the usability is maintained. And can give novelty. At the same time, each of the through holes 13 and 23 is disposed on the same line as the spring pushing direction of the spring pushing member 3 in the female/male members 1 and 2, so that the overall size of the rope fixing device can be easily shortened, thereby expanding the design. Degree of freedom. Further, since the through holes 13 and 23 are located in the vicinity of the end portions 1b and 2b on the outer side where the female/male members 1 and 2 do not overlap each other, in the use form of Fig. 2, the rope is pulled out. The pulling force of the portion 5a in the direction of the arrow is transmitted efficiently through the belt 6 as a stress in the direction in which the female/male members 1 and 2 approach each other. In the use pattern of Fig. 3, The pulling force of the belt 6 is efficiently transmitted as a stress in the direction in which the female/male members 1 and 2 approach each other, and the operation of adjusting the amount of pulling of the rope can be performed with a weak force.

(Modification) The modification of Fig. 6 is an example in which the spring portion 25 is integrally formed in the male member 2 instead of the above-described spring pushing member 3. In this description, the same reference numerals are given to the same portions as those in the above-described embodiments, and only the changed configurations will be described. That is, the male member 2 of Fig. 6 is formed with a spring portion 25 having a substantially wavy shape that is lower than the inner bottom surface of the concave portion 20. Therefore, in this modification, the number of components can be reduced and the cost can be reduced. Further, the spring portion as described above may be formed on the side of the female member 1. As described above, the cord fixing device of the present invention is not particularly limited as long as it has a configuration specified in Patent Application No. 1, and the detail can be further modified or developed in consideration of the form and the modification.
