Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a connecting fastener that can connect and tighten both ends of shoelaces, belts, or other strings or bands, and loosen the tightening as necessary.

(Prior Art) Shoes that are tied with shoelaces are made by covering the shoe, pulling both ends of the shoelace to tighten it, and manually screwing both ends of the shoelace so that the shoelace does not loosen.

(Problem that the invention seeks to solve) When taking off shoes, it is necessary to untie the bow;
Also, if you want to cover your shoes again, you must pull and tighten the shoelaces after covering them and tie them in a bow.

(Means for Solving the Problems) Therefore, the present invention provides a window hole having a width that allows the strings and bands to be connected to pass through, and a window hole to hang the ends of the strings and bands in a folded manner within the window hole. It is characterized in that the ends of two left and right Japanese character-shaped connecting pieces each having a middle crosspiece extending in the width direction are pivotally connected to each other at a fulcrum in the width direction.

(Example) In each of the illustrated examples, A and B represent the left and right Japanese character-shaped connecting pieces, 1 represents the window hole of each connecting piece, and 2 similarly represents the middle crosspiece, and each connecting piece is Japanese character-shaped. This is because the connecting piece basically has a frame portion around the window hole 1 and a middle crosspiece 2 that crosses the window hole in the width direction. The window hole 1 has a width W through which a string or band 3 to be connected can pass.

Each connecting piece A and B is made of metal, wood, plastic, etc.
Although it can be molded from any material, by molding it from plastic, it is easy to obtain a desired color that matches the shoes on which it is worn.

In order to pivotally connect one end of both connecting pieces, in the embodiment shown in FIGS. 1 to 4, an extension 5 is provided at the center of one end of one connecting piece A, with a shaft 4 protruding from both sides, and the other connecting piece A bifurcated portion 6 for receiving the extension portion 5 therebetween protrudes from one end of the piece B, and the bifurcated portion is provided with semicircular or C-shaped bearing recesses 7, 7 for accommodating the shaft 4. Therefore, while fitting the shaft 4 of the extension part 5 of one of the molded connection pieces into the bearing recesses 7, 7 of the fork part of the other connection piece, the extension part 5 is inserted between the fork parts 6, 6, and the two connection pieces are connected. Pieces A and B can be connected. In addition, when the bearing recesses 7, 7 are C-shaped, insert the shaft while pushing and expanding the opening of the recess,
This can prevent the shaft from easily coming out of the bearing recess.

The embodiment shown in FIGS. 5 and 6 is similar to the previous embodiment in that the connecting piece A has an extension 5 having a shaft 4 in the center at one end, but the other connecting piece B has a bifurcated part. Bearing holes 8, 8 into which the shafts 4, 4 are fitted
has. Therefore, in this embodiment, the shaft 4 is inserted into the bearing holes 8, 8 to connect the two connecting pieces A, B.

In this case, the shaft 4 is molded separately from the connecting piece A, and the extension part 5 of the connecting piece A is provided with a horizontal hole through which the shaft 4 passes, and the extension part 5 is inserted between the forked parts 6, 6. Align the hole in the extension part with the bearing holes 8, 8 in the bifurcated part, pass the molded shaft 4 through the aligned hole, and glue the center part of the shaft 4 to the hole in the extension part, or glue the center part of the shaft 4 to the hole in the extension part, or may be glued into the bearing holes 8, 8, or both connecting pieces A and B may be molded simultaneously with the shaft 4 fitted into the bearing holes 8, 8, or one of the connecting pieces may be molded first. After molding, another connecting piece may be molded to fit into the shaft 4 or the bearing holes 8, 8.

In addition, the connecting pieces A and B are integrally molded with one end connected to each other by a thin hinge 9 as in the embodiment shown in FIG.
The hinge 9 may be pivotable about the fulcrum.

To connect each end of the string or band 3 in a tightened state, pass each end of the string or band through one end of the opening 1 of each connecting piece from the back side, expose it, and then connect it to the middle crosspiece 2. Hang it and bring it out from the other end of the opening, guide it outward along the back surface of the other end of each connecting piece, and tighten it appropriately by pulling it. As a result, the area 3a of the string or band on the front side hanging on the middle crosspiece 2 presses the area 3b of the end of the string or band along the back side of the other end of each connecting piece to the back side of the other end of each connecting piece. , maintain the tightened state and prevent loosening.

The stronger the tightening, the more each connecting piece A and B pivots around the shaft 4 and hinge 9 as shown by dotted lines A ₁ and B ₁ , and the region 3a of the string or belt moves 3b to each connecting piece. The force to press against the back surface of the other end increases, and loosening is prevented by the pressing force which increases reasonably according to the strength of tightening.

To loosen the tightening, lift the other end of each connecting piece A, B in the direction of the arrow using the shaft 4 or hinge 9 as a fulcrum. As a result, the area 3b of the string or obi is separated upward from 3a,
Since the region 3a releases the pressing force that presses the region 3b against the back surface of the other end of each connecting piece, the string or band naturally loosens until the reaction force of the tightening force disappears. More than that,
To loosen it, just hold the area 3a side and pull it.

In each of the illustrated embodiments, the edge of the other end of the opening 1 is a slope 1 that slopes from the front to the back and toward one end.
The cross-sectional shape of the middle crosspiece 2 is a right triangular shape having a slope 2〓 that is almost parallel to the slope 1〓,
This is done in order to make it easier to pass the cord or belt through the opening 1 by folding it back at the middle crosspiece 2, and also to make it easier to pass the cord or belt through the opening 1 by cutting into the region 3a of the cord or belt at the tip edge of the slope 1 with 3b to reduce the slack in the tightened state. This is to ensure prevention, but is not necessarily necessary.

In each embodiment, a through hole 10 is provided along one side of each of the connecting pieces A and B, through which a string or belt can be passed. As a result, as shown in Fig. 1, each end of the string or belt that has been led out and tightened along the back surface of the other end of each connecting piece A, B can be folded back and passed through the through hole to give the appearance of being tied with a bow. can. This through hole 1
0 should be a little smaller than the cross-sectional area of the string or band, or should not be able to be penetrated unless the cross-sectional shape of the string or band is slightly changed, and should be able to hold the string or band lightly in the middle.

Note that the opening 1 is a concave portion 1a that bulges out at the edge of one end.
However, this is to pass through each end of the string, the tassels, metal fittings, and the hardened circular section of the tip of the flat string, and is unnecessary if the string or obi has a flat tip as well.

(Effects of the invention) As described above, according to the invention, both ends of a string or obi are pulled to form a bow, thereby preventing the tightening from loosening. It is possible to provide a tightening connector for a string or band, which can maintain a tightened state by simply pulling both ends of the string or band, and can loosen the tightening condition by simply pulling up and pivoting the other end of each connecting piece. , even young children can easily operate it, and parents don't have to worry about it.
