Description

Detailed Description of the Invention (Industrial Application!!7) The present invention relates to a clip used for locking strings such as round strings and flat strings, and more specifically, the present invention relates to a clip used for locking strings such as round strings and flat strings, and more specifically, To provide a tie-fastening clip that can create a stronger locking state as the number of locks increases.

(Prior Art and Its Disadvantages) Generally, there are various methods of locking round cords or flat cords, and there are two types: one in which the cords are fastened together, and the other in which the strings are fastened together using a buckle or other fastening device. be.

On the one hand, the tightening of such a string requires smooth and easy tightening and release, and on the other hand, on the other hand, the tightening condition must be maintained reliably so that the tightening string can be tightened smoothly and easily. The condition was that it could be prevented from coming loose or coming out by 1F.

However, all of these demands result in structures that tend to contradict each other in the locking tool, and if the locking and releasing operations are simplified, it will be difficult to maintain the locking state. This caused problems such as the garment becoming loose and unraveling.

In addition, in the case where the 9th place state is maintained reliably, there are disadvantages such as the structure of the locking tool being complicated and the vj''ti operation requiring a lot of effort.

Furthermore, in the case of a structure in which 9 fittings are easily made, and the 9 fittings are made securely to eliminate the possibility of loosening of the binding part, it takes a lot of effort or difficulty to untie the U binding part. Was.

The buckles shown in FIGS. 21 and 22 have been provided in large numbers as conventional means for connecting strings, as they combine ease of connection and unraveling operations and accuracy of adjustment. It is something that

However, in the visible buckle, when the string a is wound around the engagement rod of the buckle, each acute angle part C...C
The contact resistance that is brought into pressure contact is used to prevent removal.

As a result, when it is difficult to create sufficient contact resistance with the acute corner C...C, such as when the string a is hard and has a uniform elasticity, or when the inserted string a has a sufficient angle. If this was not done, or if an unexpected force was applied to the string a, the inserted string a would come out.

In addition, if the string a is flexible and made of a material with high friction resistance, the tightened string a will not come out from the buckle and it will be difficult to untie it. It was necessary to wrap the string a inside the buckle when tightening and loosening the connection.

(Objects and Structure of the Present Invention) The strap fastening clip according to the present invention has been proposed as a solution to the inconveniences in the prior art, and includes:
A stopper built into the clip body is pushed in the tightening direction of the string by the string inserted into the clip main body, thereby assisting the tightening of the string and releasing the string. I tried to do it with the glorious push-up operation of the par.

That is, the string fastening clip according to the present invention is composed of a clip main body A through which a string C is inserted, and a stopper B assembled to this clip main body A. The clip main body A is composed of a locking piece 2 integrally connected to a child part l, and the clip main body A has a cavity 3 into which the locking piece 2 of the stopper B is loaded in an engaged state. The locking piece 2 of the stopper B is located relatively at the bottom of the empty chamber 3 and at a side position of the bottom.
A rod-shaped or plate-shaped fastening piece 4 having a folded back wall 4a for the insertion string C is provided at a side position of the clip, and the inside of the clip main body A is partitioned by this fastening piece 4 to form an insertion hole 5 for the string C. Moreover, this insertion hole 5 is configured to communicate with the empty chamber 3.

(Operations and Effects) The string fastening clip according to the present invention has the above structure, and the string C inserted into the empty chamber 3 from the lower surface side of the clip main body A.
The string C is pulled in the direction of the arrow y while the string C is led out from the hole 5 bypassing the fastening piece 4 and tightened to the desired position.Then, with this tightened state y, the stopper B is tightened. By pushing in, the string C connects the stopper B to the wall 4 of the adhesive piece 4.
It will be clamped and locked between a and a.

When the tension on string C is released in this state, string C will be strongly pulled in the direction of arrow X.
The E piece 2 is further pushed downward by the string C, and the wall portion 4
To effectively pinch and lock the string C between a and a.

In addition, if the string C is released from the tension while the string C is sufficiently tightened in the direction of arrow y, the string will be pulled back in the direction of X, and this return movement in the X direction will cause It was confirmed that the locking piece 2 of the stopper B could be pushed downward to create a locking state similar to that described above.

As a result, when it is not necessary to tighten the string at a precise position, the string can be tightened by tightening the string C and releasing the string C, without having to perform the manual pushing operation of stroke 2 par B. This made it possible to correct the

Next, the string C that has been tightened is connected to the knob l of the stopper B.
By pulling up the locking piece part 2 upwardly, the pinched state between the locking piece part 2 and the wall part 4a is released, and the locking piece part 2 can be freely inserted and removed.

In addition, even when the string C is released from this straightened state, if the string C can be further tightened in the y direction, that is, if there is some margin left in tightening the string C, the string C can be tightened in the y direction. By pulling it out, it is possible to push the locking piece 2 of the stopper B upward from the side of the wall 4a, and thereby the string C is released from the pressure between the locking piece 2 and the wall 4a. This made it possible to freely insert and remove it.

The string clasp meclip according to the present invention has a string C by the above operation.
Since the tightening is done by pulling the string C in the y direction, no more contact resistance than necessary is generated between the string C and the connecting piece 4 when the string C is tightened, and the string C is tightened. It was considered easy.

Also, in this state, by pushing the stopper B inward or returning the string C in the X direction, the string C is pressed between the locking piece 2 of the stopper B and the wall 4a. Locked, string C
It was possible to remove the screws and ensure that they did not come loose.

In particular, when the string C is pulled in the X direction, the locking piece 2 of the stopper B is pulled further downward from the wall 4a, so that the string C can be adjusted more reliably. There is.

The string C that has been further tightened and adjusted is It has the feature that it can be easily pulled out from the clip due to the low friction resistance between the buckles, and effectively eliminates the drawbacks of conventional buckles, which tend to be difficult to release smoothly due to the compactness of the clip. ing.

(Embodiment) Hereinafter, a typical embodiment of the lace-fastening clip according to the present invention will be described with reference to the accompanying drawings.

First, when the clip main body A is placed between the opposing top wall a and the bottom wall,
It forms a cylindrical body composed of opposing side walls C and C, and a window hole 6.7 communicating with the cylindrical body is provided in the top wall a and the bottom wall to lock the so-called stopper B. A vacant chamber 3 into which the piece 2 is loaded was formed.

Incidentally, the window hole 6 is made slightly wider on both cylinder end sides than the window hole 7, and has a tapered surface 4a' having a non-slip rib on the inner upper surface of the connecting piece 4, which is a part of the bottom wall. The connecting piece 4 has a tapered surface 4a'' on the inside lower surface along with the insertion groove 8 for the string C on the lower side of the bottom wall. It consists of

Note that by reducing the width of the insertion groove 8 from the outside toward the inside and providing tapered side walls 8' and 8' as shown in FIG. 5, the width A of the string C to be inserted is gradually narrowed down. It has been made possible to reduce the overall width of the re-flip main body A by being compressed to the width A. In addition, an insertion hole 5 for a string C is provided between the connecting piece 4, which is a part of the bottom wall constituting the wall portion 4a, and the top wall a. An engagement groove 9 is provided above the lower edge of the side wall C, and a wide four-step surface 1 is provided on the outer surface of the side wall C between the upper and lower edges.
0 is provided for engagement with a stopper B, which will be explained later, and the outer edge of the upper end of the recessed step surface 10 of the side wall C is made into a 7-round or tapered surface to make the vertical sliding of the stopper B smooth. There is.

Next, the stopper B includes a substantially mouth-shaped knob portion 1 having a top wall 1b covering the window hole 6 and wing pieces 1a, 1a fitted onto the concave step surface 10 of the side wall C, and this knob portion. 1, the wing piece 1a
, a locking piece 2 integrally provided on the top 1ib so as to be sandwiched between the blades 1a, and an engaging protrusion 11 provided at the lower part of the locking piece 2 on the side of the wing 1a. At the same time, a groove 12 is formed in the lower part of the locking piece 2 on the side facing the wall 4a.
12 a. Also, wing pieces 1a, 1a
Ribs are provided on the periphery to prevent slipping.

The visible stopper B is made by pressing the side wall C from the side of the window hole 6 of the clip body so that the wing piece 1a of the stopper B and the locking piece part 2 sandwich the engaging protrusion 11 in the flesh of the side wall C. The stopper B is inserted into the groove 9 beyond the thick part, and is easy to assemble since it is prevented from coming out later. The mating protrusion 11 and the wing piece 1a are slidably moved evenly in the vertical direction in which they are engaged.

Next, the string C, which is led out from the hole 5 from the groove 8 on the lower surface side of the clip, bypassing the tension piece 4, is directed toward the wall 4a of the tension piece 4 by the jaw 12a on the lower edge of the locking piece 2 of the clip B. Pressure-welded,
It is arranged to fit into the groove 12 while biting into the acute-angled surfaces 4a' and 4a'' constituting the wall portion 4a.

In this state, the string C receives a force that pulls it back in the direction of the arrow This effectively prevents the string C from coming loose.

(Other embodiments) In the clip shown in FIG. 6, the wing piece 1a of the stopper B
An engaging protrusion 11 is provided on the inside of the clip body, and a groove 9 into which the protrusion 11 is engaged is provided in a recessed stepped surface IO provided on the side wall C of the clip body. Further, the projection 11 has a notched taper 11a on its lower surface, so that it is suitable for sliding engagement into the groove 9.

In addition, in the clips shown in FIGS. 7 to 9, the knob 1 of the stopper B is shaped so as to protrude upward from the top wall a, and is not configured to straddle between the side walls C and C mentioned above. It is designed so that it can be grasped from both ends of the cylinder, and protrusions 11 are provided on both side wall surfaces of the knob 1 so as to engage with the grooves 9.

Furthermore, the clip shown in FIGS. 10 to 12 has a clip main body A having a cylindrical shape with constrictions on both sides, so that it can be adapted to fasten a round cord or the like.

Further, the clip shown in FIGS. 13 to 15 is an embodiment in which one side of the string C is fixed, and functions in the same manner as a normal buckle.

Next, the clip shown in FIGS. 16 to 20 is related to the end treatment of the string C that is tightly fastened with the clip, and the string is attached to the top wall lb of the knob 1 of the stopper B using a hole or an elastic piece. The insertion slit 13 of C is installed as shown in FIG.
The end of the string C is treated in an appropriate manner as shown in Figure 0, and when the knob l is released, the string C functions so that the loop C° portion loosens, and the string C It has the feature of giving a feeling of being tied together.

Furthermore, in the clip shown in FIGS. 21 to 23, the insertion slit 7) 13 of the above embodiment is omitted, and a slit 14 for processing the end of the string C is formed in the clip body A. The slit 14 is configured such that a tight fitting piece 15 is disposed outside the tight fitting piece 4 and communicates with the insertion hole 5 between the tight fitting pieces 4 and 15.

As a result, the end of the string C led out from the insertion hole 5 is folded back again and inserted through the slit 14 from the insertion hole 5, and is led out from the insertion groove 8 while contacting its own string C. It is said to be easy to handle and has the advantage of creating an elegant appearance as if the string C was tied.
