Hereinafter, a typical embodiment of the present invention will be described with reference to FIGS. The cord lock according to this embodiment can be fastened to an arbitrary position of the cord R, and is configured to be released by pushing the second member 2 against the biasing operation. It has been done.

If the cord R can be fastened in this manner, the shape (round cord, flat cord, etc.), material and structure (knitted cord, rubber cord, synthetic resin cord, etc.) of the cord R may be any. I will not. Such a cord lock is typically fastened to the cord R in various articles having portions to be squeezed or tightened by the cord R, and the fastening position thereof is changed. Used to squeeze or loosen the points.

Such a cord lock includes a first member 1, a second member 2, and an urging means 3.

The first member 1 has a first passage portion 4 and a second passage portion 5 of the cord R. In the illustrated example, the first member 1 has a side surface portion 6 and a bottom surface portion 7, and supports the second member 2 so as to be movable up and down.

The second member 2 is combined with the first member 1 so as to be able to move up and down with the second passing portion 5 side as a fulcrum 19, and the first passing portion 4 and the second passage on the free end 20 side of the lifting operation. A third passage portion 21 is provided between the portion 5 and the cord R to pass therethrough.

The fulcrum 19 is constituted by an engaging portion formed on one of the first member 1 and the second member 2 and an engaged portion formed on the other of these and engaged with the engaging portion. ing.

The biasing means 3 biases the second member 2 in the standing direction. In the first example shown in FIGS. 1 to 18, the second example shown in FIG. 19, the third example shown in FIGS. 20 and 21, and the fourth example shown in FIGS. The urging means 3 is constituted by a compression coil spring 28. On the other hand, in the fifth example shown in FIGS. 24 to 36 and the sixth example shown in FIG. 37, the urging means 3 is constituted by a part of the second member 2.

In the state where the cord R is pushed against the urging force of the urging means 3 and the second member 2 is pushed in and the first passage portion 4 and the third passage portion 21 are aligned so as to pass the cord R against the cord lock. The first passage portion 4 can be inserted through the third passage portion 21 and pulled out from the second passage portion 5. Alternatively, the cord R with respect to the cord lock pushes the second member 2 against the urging force of the urging means 3 to align the first passage portion 4 and the third passage portion 21 so that the cord R can pass. In this state, the second passage portion 5 can be inserted through the third passage portion 21 and pulled out from the first passage portion 4. When the pushing of the second member 2 is stopped after passing the cord R through the cord lock in this way, the second member 2 is rotated in the standing direction by the urging force of the urging means 3. A state in which the passage portion 4 and the third passage portion 21 are not aligned is created, and thereby the cord lock is fastened to the cord R. The pushing of the second member 2 includes a case where the second member 2 is pushed relatively.

When the fulcrum 19 is composed of a shaft and a shaft hole, typically, the side surface portion 6 of the first member 1 needs a certain thickness in order to provide the shaft hole. Further, when the cord R passes through the fulcrum 19, the thickness of the cord lock on the fulcrum 19 side cannot be less than the thickness of the cord R. On the other hand, in the cord lock according to this embodiment, the fulcrum 19 includes the engaging portion and the engaged portion, and the cord R drawn from the second passage portion 5 is the fulcrum. Since the second member 2 is positioned closer to the free end 20 side than 19, the fulcrum 19 can be formed so as not to affect the thickness of the cord lock.

In particular, in this embodiment, one of the engaging portion and the engaged portion is provided on the bottom surface portion 7 side of the first member 1, and the thickness of the first member 1 is made as much as possible. Can be made smaller.

More specifically, in the first to fourth examples, the engaging portion is constituted by the engaging claw 22, and the engaged portion is engaged with the engaging claw 22 being engaged. The hole 8 is used.

少なくとも At least a part of the second passage portion 5 is positioned on the free end 20 side of the second member 2 with respect to the fulcrum 19. As a result, in the cord lock according to this embodiment, the cord R passed through the cord lock as described above is straight between the first passage portion 4 and the second passage portion 5. It can be fastened to the cord R in a state where it is bent or curved at the two passage portion 5 and pulled out to the side before the fulcrum 19 (on the free end 20 side) (FIG. 12). .

Further, in the first example shown in FIGS. 1 to 18, the second example shown in FIG. 19, and the third example shown in FIGS. 20 and 21, the second passage portion 5 has the side surface portion. 6 and the bottom surface portion 7. Thereby, in the first to third examples, the area of the second passage portion 5 can be maximized without increasing the thickness of the first member 1, and the second passage portion 5 The cord lock can be fastened to the cord R so that the cord R is pulled out in any direction.

In the cord locks according to the first to third examples, the bottom surface portion 7 of the first member 1 is bent or curved so that the fulcrum 19 side is bent or curved inside. In this case, when the cord R drawn out from the second passage portion 5 functions to squeeze a part of the article, the bottom surface portion 7 of the first member 1 located on the free end 20 side of the second member 2 is used. The article can be provided with a cord lock so that a gap S is formed between the article and the outer surface of the article, and the bottom surface portion 7 of the first member 1 is in close contact with the outer surface of the article on the fulcrum 19 side. The pushing operation of the 2nd member 2 which cancels | fastens R becomes easy. For example, as shown in FIG. 11, a cord lock is placed on the cord R that narrows the opening Ga of the glove G, the bottom surface portion 7 of the first member 1 positioned on the free end 20 side of the second member 2 and the opening of the glove G. It can be fastened in a state in which a gap S is formed between the outer surface on the Ga side.

The cord lock according to the first to third examples includes a guide wall that guides the cord R inserted from one of the first passage portion 4 and the second passage portion 5 to the other of them. In this case, the cord R passed through the cord lock as described above is straight between the first passage portion 4 and the second passage portion 5 but is bent or curved in the second passage portion 5. In the case of being pulled out to the side, the cord R inserted from the second passage portion 5 side can be reliably guided to the first passage portion 4.

More specifically, in the cord locks according to the first to third examples, the guide wall is a first guide wall 9 (for example, the first example) formed inside the first member 1. 15) and the first guide wall 9 formed inside the second member 2 and in a state where the second member 2 is laid down against the urging force of the urging means 3. The second guide wall 23 forms a part of the insertion path of the cord R in cooperation with each other.

The cord lock according to the first to third examples is in a state where the second member 2 is pushed into the bottom surface portion 7 of the first member 1 against the urging force of the urging means 3. The second member 2 is provided with a recess 7a for accommodating the free end 20 side so as not to cause a step between the third passage portion 21 and the bottom surface portion 7 (for example, FIG. 9 relating to the first example).

A wall 23 is formed (see FIG. 17). The second guide wall 23 is formed between the bulging portion 24 and the middle position in the length direction of the second member 2 so as to be continuous with the hole wall on the side of the center line L1 of the third passage portion 21. Has been.

An engaging claw 22 serving as the engaging portion is formed on the fulcrum 19 side of the second member 2 (see FIG. 17). The engaging claw 22 is constituted by a protrusion 22b protruding on the opposite side to the bulging portion 24 formed at the tip of the elastic leg 22a protruding from the inner surface of the substrate portion 2a on the center line L1.

A protruding protrusion 27 that catches the first passage portion 4 is formed inside the first member 1 on the protruding end of the bulging portion 24 on the side opposite to the fulcrum 19 side. (See FIG. 16).

The first member 1 and the second member 2 are configured such that a spring 28 is interposed between the first member 1 and the second member 2 by using the bottomed hole 25 and the protrusion 7b. The second member 2 is pushed into the one member 1 to be combined with one touch. That is, the bridging portion 13 and the elastic leg 22a are temporarily elastically deformed by the engaging claw 22 pressed against the bridging portion 13 by such pushing, and the engagement claw 22 of the bridging portion 13 is allowed to get over. When 22 enters the notched portion 14, the engagement claw 22 is engaged with the bridging portion 13 by elastic recovery, and the second member 2 is combined with the first member 1 so that the second member 2 can move up and down with this engagement point as a fulcrum 19. It is supposed to be.

When the cord 2 does not pass through the second member 2, the urging means 3 urges the retaining protrusion 27 to hook onto the hole wall located on the protruding end side of the side surface portion 6 of the first passage portion 4. It is positioned in the standing position. In this state, the first passage portion 4 and the third passage portion 21 are not aligned and the cord R cannot pass through the cord lock (FIG. 9). When the cord lock is picked at the free end 20 side so as to push the free end 20 side of the second member 2 against the bias, the bulging portion 24 enters the recess 7a inside the cord lock, The first passage portion 4 and the third passage portion 21 are aligned so as not to cause a step between the bottom surface portion 7 and the third passage portion 21, and the first guide wall 9 and the second guide wall 23 are An insertion passage for the tubular cord R is formed between the first passage portion 4 and the second passage portion 5 (see FIGS. 8 and 10). As a result, the cord R can be smoothly passed from the first passage portion 4 toward the second passage portion 5, and conversely, the cord R can also be directed from the second passage portion 5 toward the first passage portion 4.

The first member 1 is provided with a support portion 29 that abuts against the elastic deformable portion f and causes the elastic deformable portion f to be elastically deformed (see FIG. 26 and 27).

In the example shown in the figure, the code lock of the fifth example has an aspect having a length and a width. In this fifth example, a single cord R (fifth example) is placed in the cord lock so as to follow a virtual center line z (FIGS. 24 and 29) passing through the middle position in the width direction of the cord lock. Is omitted in the drawing in which the description is given.).

In the cord lock of the fifth example, the first member 1 includes a bottom surface portion 7 having a length and a width, and a side surface portion 6d in the length direction positioned on the left and right sides with the virtual center line z interposed therebetween. 6d and two side portions 6e and 6e in the width direction, and the side opposite to the bottom portion 7 is opened. In the example shown in FIG. 26, the rising dimension of the side surface part 6e in the width direction positioned on the left side in FIG. 26 is larger than the rising dimension of the side surface part 6e in the width direction positioned on the right side. The protruding dimension of the portion 6d from the bottom surface portion 7 is gradually reduced from the left side to the right side in FIG. In the illustrated example, the first member 1 further has one surface located on the same surface as the inner surface 7c of the bottom surface portion 7 and the other surface on the left and right sides in FIG. The tongue piece portion 30 is provided so as to protrude outward from the base portion of the side surface portion 6e in the width direction so as to be positioned on the same surface. In this example, the cord lock can be fastened to the use object of the cord lock by sewing or welding using the tongue piece 30. The first passage portion 4 is formed so as to penetrate the width side surface portion 6e located on the left side of FIG. In the illustrated example, a rectangular through hole 31 is formed in the bottom surface portion 7 at a position directly below the first passage portion 4. On the other hand, the second passage portion 5 is formed so as to penetrate the position on the virtual center line z in the bottom surface portion 7 on the right side of FIG. 26 (FIG. 29). A through hole 32 larger than the second passage portion 5 is formed between the second passage portion 5 and the side surface portion 6e in the width direction located on the right side in FIG. 26 (FIG. 29). The through hole 32 and the second passage portion 5 are communicated with each other by a communication hole 33 that gradually decreases the hole width as it approaches the second passage portion 5 side. Further, a protruding portion 34 protruding inward from the inner surface of the side surface portion 6e in the width direction is formed immediately above the through hole 32. In this example, the protruding portion 34 functions as the engaged portion. It is supposed to be. Further, in this example, the support portion 29 is formed between a position in the middle of the length direction of the first member 1 and the second passage portion 5. In this example, the support portions 29 are respectively provided on the left and right sides of the virtual center line z. Each of the left and

right support portions

29 and 29 has a columnar shape in which the lower end is integrated with the bottom surface portion 7 and a part of the side portion is integrated with the inner surface of the side surface portion 6d in the length direction. An interval through which the cord R passes is formed between the portions 29 and 29 (see FIG. 32).

On the other hand, in the cord lock of the fifth example, the second member 2 includes a substrate portion 35 having a length and a width, a third passage portion 21, an inner plate portion 36, and the engaging portion (for example, And a tongue piece 38) to be described later. The substrate portion 35 has an outer shape that complementarily fits in a space surrounded by the four side surface portions 6d... 6e of the first member 1. One surface 35a of the substrate portion 35 constitutes the outer surface of the code lock. The inner plate portion 36 is shorter than the substrate portion 35 and is sized to fit in the space in the first member 1. The inner plate portion 36 and the substrate portion 35 are provided with an interval for allowing the cord R to pass between the inner plate portion 36 and the substrate portion 35 via the connecting portion 37 on the free end 20 side of the second member 2. Is integrated. The third passage portion 21 is formed so as to penetrate the connecting portion 37 in a direction along the length direction of the second member 2. The engaging portion is constituted by a tongue piece 38 protruding so as to form a step 38 a on one surface side of the substrate portion 35 on the fulcrum 19 side of the second member 2 of the substrate portion 35.

The distance from the free end 35b of the substrate portion 35, which is the free end 20 of the second member 2, to the step 38a is substantially equal to the distance between the two side portions 6e, 6e in the width direction of the first member 1. However, the distance between the free end 20 and the tip of the tongue 38 is greater than this. In the illustrated example, the first member 1 and the second member 2 are configured such that a tongue piece 38 serving as the engaging portion is placed below the projecting portion 34 serving as the engaged portion. A portion that contacts the piece 38 is combined as the fulcrum 19. Further, in this combined state, the protruding end 36 a side of the inner side plate portion 36 comes into contact with the bottom surface portion 7 of the first member 1 between the first passage portion 4 and the support portion 29. In the illustrated example, it is the free end 20 of the second member, below the entrance of the third communication portion 5, more specifically, at the entrance of the third passage portion 21, and inside the connection portion 37. A claw portion 39 is formed on the side where the plate portion 36 is connected. And the said combined state of the 1st member 1 and the 2nd member 2 is maintained by hooking the said nail | claw part 39 to the inner surface located in the protrusion end side of the side part 6e of the said width direction in the 1st passage part 4. FIG. (FIG. 26). Specifically, the free end 20 side of the second member 2 is placed in the space of the first member 1 from the state in which the tongue piece 38 serving as the engaging portion is placed below the protruding portion 34 serving as the engaged portion. When the claw portion 39 is pushed in, the claw portion 39 abuts against the protruding end of the side surface portion 6e in the width direction to cause elastic deformation mainly on the first member 1 side. The pushing-in to be inserted is allowed, and the claw portion 39 is caught on the inner surface of the first passage portion 4 by the subsequent elastic return. And in the state combined as mentioned above, the said inner side board part 36 produces an elastic deformation in the direction which narrows the distance between the said board | substrate parts 35 (FIG. 26). In this state, the first passage portion 4 and the third passage portion 21 are not aligned (FIG. 26). When the free end 20 of the second member 2 is pushed in, a portion of the base plate portion 35 located closer to the free end 20 than the support portion 29 is elastically deformed so that the support portion 29 is the deformation center. A state is created in which the first passage portion 4 and the third passage portion 21 are aligned. In this aligned state, the cord R can be inserted into the cord lock through the first passage portion 4, the second passage portion 5, and the third passage portion 21. After the cord R is inserted, when the pushing operation of the second member 2 is stopped, the substrate portion 35 and the inner plate portion 36 are elastically restored, and the first passage portion 4 and the third passage portion 21 are misaligned. Therefore, the cord lock is fastened to the cord R by the elastic restoring biasing force.

That is, the cord lock of the fifth example does not require the separate urging means 3 unlike the cord locks of the first to fourth examples. In the cord lock of the fifth example, the urging means 3 is a part of the second member 2 and extends from the third passage portion 21 side to the fulcrum 19 side. The inner plate portion 36 as the elastically deformable portion f that forms an insertion path for the cord R between the two member 2 and the substrate portion 35 and is in contact with the first member 1, and the substrate portion 35.

The urging means 3 may be composed of only the inner plate portion 36, and the substrate portion 35 may not include the elastically deformable portion f. In this case, the support portion 29 is unnecessary. .

(Sixth example)
In the cord lock of the sixth example shown in FIG. 37, the urging means 3 is part of the second member 2 and is elastically deformed provided between the third passage portion 21 and the fulcrum 19. The second member 2 is provided with a support portion 40 that abuts on the first member 1 and causes the elastically deformable portion f to be elastically deformed. In the illustrated example, the other surface 35 c of the substrate portion 35 of the second member 2 faces the bottom surface portion 7 of the first member 1, between the third passage portion 21 and the fulcrum 19, and on the inner plate. The support portion 40 is formed closer to the fulcrum 19 than the portion 36. The support portions 40 are provided on the left and right sides of the virtual center line z. Each of the left and

right support portions

40 and 40 has a columnar shape in which the upper end is integrated with the inner surface of the substrate portion 35, and an interval through which a cord passes is formed between the left and

right support portions

40 and 40. .

The remaining configuration of the sixth example is substantially the same as that of the fifth example including the first member 1, and therefore the same reference numerals as those used in the first example are shown in the drawing showing the fifth example. The description will be omitted with reference to 37.

The provision of this characteristic to the portion to be provided with the elastic deformation characteristic in the cord lock of each example described above can be easily ensured by using the first member 1 and the second member 2 as plastic molded products. it can.
