Description

The present invention relates to a hanao locking device for locking and fixing the end of the hanao to a footwear base such as sandals, and a footwear provided with the hanao locking tool.

With conventional footwear with a hanao, a high level of skill is required for the work of inserting the hanao, and it is difficult for the user to insert the hanao by himself / herself. Therefore, it took a lot of time and money to replace the thong with a new one.

On the other hand, it is known that the end of the hanao is locked and fixed to the footwear base by using a member called a hanao locking tool. For example, Patent Document 1 describes that a fixing bracket as a hanao locking tool is stored and used in a storage recess on the back side of the table. In Patent Document 1, a loop-shaped locking string is provided at the end of the hanao, and the end of the hanao is locked to the base by hooking the locking string on the fixing bracket.

In Patent Document 2, a mounting device for a rotating body is provided in the anterior hanao mounting hole, and the anterior hanao core is serrated and rotatably provided on the rotating body formed by combining the portions of the rotating body cut in half. A configuration is described in which the anterior hanao is moved up and down and adjusted by rotating a rotating body with a screw that moves the anterior hanao inside.

Registered Utility Model No. 3109268 Japanese Unexamined Patent Publication No. 2006-6350

The thong locking tool of Patent Document 1 has a structure in which the loop-shaped locking string is easily disengaged from the fixing bracket, so that the thong can be replaced relatively easily. However, since this hanao locking tool is configured to fix the hanao at the loop position, it is not suitable for adjusting the length of the hanao on the table.
On the other hand, Patent Document 1 also describes an example in which three loops are continuously arranged at the end of the thong, but even with this configuration, the length of the thong cannot be adjusted steplessly, and the user is advised. It is difficult to make fine adjustments accordingly.

In the hanao locking structure described in Patent Document 2, the anterior hanao must be formed by a special member whose lower end is serrated. Moreover, in order to fix the hanao so that the length can be adjusted, in addition to the rotating body that holds the lower end of the anterior hanao, a mounting device for the rotating body is also required, which causes a problem that the number of parts increases.

The present invention has been made in view of this point, and the main object thereof is to provide a hanao locking tool with a structure in which the number of parts is small while the end of the hanao does not need to be specially processed. The length is adjustable and fixed.

As shown in FIG. 3, the second member 12 has a second base portion 31 and a recess 32 formed in a substantially central portion of the second base portion 31. The recess 32 is open to the first member 11 side. Further, in the second base portion 31, a notch portion 33 is formed in the upper portion thereof, and a key groove portion 35 is formed in a notch shape in a side portion on the side opposite to the hinge portion 13. The keyway portion 35 is, for example, a rectangular notch groove.

As shown in FIG. 3, the first member 11 has a first base portion 21 and a convex portion 22 formed in a substantially central portion of the first base portion 21. The convex portion 22 projects toward the second member 12, and is configured to be inserted into the concave portion 32 when the first member 11 is combined with the second member 12 (that is, in a closed state). As shown in FIG. 5, a gap 40 is formed between the convex portion 22 and the concave portion 32 in the closed state. The end 15 of the hanao 3 is accommodated in this gap 40. The width and shape of the gap 40 are not limited to the shape shown in FIG. 5, and can be appropriately changed according to the thickness of the end portion 15 of the hanao 3 to be accommodated.

As shown in FIG. 3, in the convex portion 22, a portion arranged at the center of the first base portion 21 is formed in a semicircular shape, for example. Further, the convex portion 22 is provided with a plurality of protrusions 23 protruding toward the second member 12 side at predetermined intervals. The plurality of protrusions 23 project radially toward the side of the second member 12.

One side portion of the convex portion 22 extends from the central side of the first base portion 21 to the side end portion, and the side end portion thereof is the key portion 25. The key portion 25 is adapted to fit into the key groove portion 35 of the second base portion 31 in a closed state of the first member 11 and the second member 12.

Further, as shown in FIG. 4, in the closed state of the first member 11 and the second member 12, the cutout portion 33 of the second base portion 31 constitutes a hanao insertion portion 17 with the first base portion 21. It is supposed to do. The gap 40 communicates with the outside by the hanao insertion portion 17. The hanao insertion portion 17 can be formed not only on the upper side of the hanao locking tool 10 but also on the lower side.
In this way, as shown in FIG. 10, the first member 11 and the second member 12 have the end portion 15 of the hanao 3 bent by the surface of the convex portion 22 and the surface of the concave portion 32 in the hanao incorporated state. It is configured to be pinched.

When the hanao 3 is attached to the pedestal 2, the end portion 15 of the hanao 3 is inserted into the through hole 7 from the upper side of the pedestal 2 and passed through the mounting hole 5. Next, as shown in FIG. 6, the first member 11 and the second member 12 are opened, and the end portion 15 of the thong 3 is arranged between the first member 11 and the second member 12. Subsequently, as shown in FIGS. 7 to 9, by deforming the first member 11 and the second member 12 into a closed state, the end portion 15 of the hanao 3 is placed between the first member 11 and the second member 12.

At this time, since the convex portion 22 is formed with a plurality of protrusions 23 that project radially toward the second member 12, the first member 11 and the second member 12 are formed as shown in FIGS. 6 to 9. When deforming from the open state to the closed state, the end portion 15 of the thong 3 inserted between the first member 11 and the second member 12 can be sandwiched while being wound toward the hinge portion 13. In this way, the first member 11 and the second member 12 are in the state of incorporating the thong.

After that, the first member 11 and the second member 12 in the thong-embedded state are inserted into the mounting hole 5 from below. At this time, the first member 11 and the second member 12 receive an elastic compressive force from the inner wall 9 of the mounting hole 5 in the state where the thong is incorporated. As a result, the first member 11 and the second member 12 are fixed to the base 2 in the mounting hole 5 and sandwich the end portion 15 of the thong 3.

Therefore, according to the hanao locking tool 10 of the present embodiment, first, the first member 11 and the second member 12 in the hanao built-in state are inserted into the mounting holes 5 and fixed. The thong 3 can be easily replaced by the operation of attaching and detaching the second member 12 to the base 2. Further, since the end portion 15 of the hanao 3 can be sandwiched between the first member 11 and the second member 12 at an arbitrary position, the length of the hanao 3 on the table 2 can be appropriately adjusted. Moreover, the first member 11 and the second member 12 are fixed to the base 2 by the elastic compressive force received from the inner wall 9 of the mounting hole 5, and at the same time, the end portion of the thong 3 is fixed by the first member 11 and the second member 12. Since the 15 is sandwiched in the bent state, the end portion 15 of the hanao 3 can be securely fixed to the pedestal 2 together with the hanao locking tool 10.
That is, according to the hanao locking tool 10 of the present embodiment, even if the end portion 15 of the hanao 3 is not specially processed, the hanao 3 is provided with a configuration in which the number of parts of the first member 11 and the second member 12 is small. It can be fixed so that the length can be adjusted.

Further, as shown in FIG. 10, since the end portion 15 of the hanao 3 is sandwiched between the surface of the convex portion 22 of the first member 11 and the surface of the concave portion 32 of the second member 12 in a bent state, the sandals 1 Even if a force that pulls the hanao 3 from the hanao locking tool 10 acts during use, the hanao 3 can be reliably held and the displacement can be prevented. Therefore, the length of the thong 3 on the table 2 can be appropriately maintained.

In addition to that, when the end portion 15 of the hanao 3 is sandwiched between the first member 11 and the second member 12, a plurality of protrusions 23 bite into the end portion 15 of the hanao 3, so that the hanao 3 is displaced. It can be prevented more reliably.

Further, since the first member 11 and the second member 12 are connected by the hinge portion 13, the hanao locking tool 10 can be easily handled as one part, and the work of sandwiching the end portion 15 of the hanao 3 becomes easy. ..

Here, when the hinge portion 13 is provided, the gap 40 between the first member 11 and the second member 12 becomes narrower on the hinge portion 13 side, but to the second member 12 side which is lateral to the convex portion of the first member. Since a plurality of protrusions 23 that protrude radially are provided, as shown in FIGS. 6 to 9, when the first member 11 and the second member 12 are deformed from the open state to the closed state, the end of the hinge 3 is provided. The portion 15 can be wound toward the hinge portion 13 side by the plurality of protrusions 23.

As a result, while the first member 11 and the second member 12 are connected by the hinge portion 13 to facilitate the handling of the hanao locking tool 10, the end portion 15 of the hanao 3 is connected to the first member 11 and the second member 12. It can be firmly sandwiched between the hinge portion 13 and the hinge portion 13.

Here, as shown in FIG. 11, when the end portion 15 of the thong 3 is pulled upward as shown by the arrow A in the figure, the thong locking tool 10 is attached to the arrow B and the arrow C in the same figure. As shown, the force acts so that the upper end side opens to the left and right. On the other hand, in the present embodiment, the key portion 25 is formed in the first member 11, while the key groove portion 35 is formed in the second member 12, and the key portion is in a closed state of the first member 11 and the second member 12. Since the 25 is fitted into the keyway portion 35, it is possible to make it difficult to open the upper end side of the hanao locking tool 10 to the left or right against the forces shown by the arrows B and C. Therefore, even when the sandals 1 are used, the first member 11 and the second member 12 can be maintained in a closed state, and the end portion 15 of the hanao 3 can be firmly locked and fixed to the base 2.

The shapes of the key portion 25 and the key groove portion 35 are not limited to the rectangular shape as described above, and may be other shapes. For example, as shown in FIG. 12, which is another embodiment, the shape of the key portion 25 and the key groove portion 35 may be triangular. Even in this way, the closed state of the first member 11 and the second member 12 can be appropriately maintained.

Further, the convex portion 22 and the protrusion 23 formed on the first member 11 are not limited to the semicircular plate-shaped convex portion 22 and the radial protrusion 23 as described above, and may have other shapes. For example, as shown in FIG. 13 which is another embodiment, the convex portion 22 may have a shape in which the protrusion width toward the second member 12 side is constant and extends to both the left and right sides of the first member 11. In this case, it is preferable to provide the key portion 25 at one side end of the convex portion 22 as described above. Then, a plurality of protrusions 23 may be arranged at predetermined intervals on the second member 12 side of the convex portion 22. Even in this way, the end portion 15 of the hanao 3 can be sandwiched between the first member 11 and the second member 12 in a bent state, and the plurality of protrusions 23 can appropriately prevent the hanao 3 from being displaced.

As described above, the present invention is useful for a hanao locking tool for locking the hanao to a footwear table such as sandals and a footwear provided with the hanao locking tool.
