There was a problem that it could easily fall off.

The object of the present invention is to provide a belt size adjustment fitting that can solve the above-mentioned conventional problems.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a substrate with connecting ends that are separated at the middle of the belt and are to be connected to each other, and are inserted into the back side of the substrate from both sides of the substrate. Provides an insertion part,
Each insertion port opening on both sides of the insertion portion is provided with a bearing portion, one end of each presser plate is pivoted to each bearing portion, and one end of each presser plate is provided with a hooking claw. In the belt size adjustment fitting, the other end of each presser plate is a free end for rotationally moving each of the engaging pawls using the shaft attachment portion as a fulcrum, and one of the insertion portions is provided. The free end of the presser plate, which is pivoted to the bearing part of the insertion opening, is rotated to a position where the hooking claw is completely inserted into one connecting end of the belt inserted into the insertion part. A stopper part formed to abut against the back surface of the board is provided, and a free end of the presser plate is pivoted to the bearing part of the other insertion opening of the insertion part, and a hooking claw is inserted into the insertion part. When the belt is rotated to a position where it completely bites into the other connecting end, insert a stopper part formed so as to abut against the pivoting part of the presser plate pivoted to one of the insertion openings. It is characterized by providing.

[Effect]

Insert one of the connecting ends, which are the ends separated at the middle of the belt and are to be connected to each other, into the insertion part on the back side of the board from one of the insertion openings, and When the free end of the presser plate is rotated in a direction closer to the back surface of the board, the engaging claws rotate and move so as to gradually bite into the above-mentioned connecting ends, and the engaging claws bite into the above-mentioned connecting ends most deeply. When it rotates to the fully biting position, the stopper portion provided at the free end of the holding plate abuts against the back surface of the board, stopping further rotational movement of the engaging claw. Also, insert the other connecting end of the above-mentioned connecting ends of the belt into the insertion hole on the back side of the board, and move the free end of the other presser plate closer to the back side of the board. As you turn it, the engaging pawl will rotate so that it gradually bites into the connecting end,
The position where the hooking claw digs into the connecting end most deeply,
In other words, when rotated to the position where it bites completely,
The stopper part provided at the free end of the presser plate abuts against the pivoting part of one of the presser plates and stops further rotational movement of the engaging pawl, so that each connecting end of the belt to be connected to each other is It is connected by being inserted into the back side of the board.

〔Example〕

Embodiments of the present invention will be described below based on FIGS. 1 to 8 of the drawings. Reference numeral 20 denotes a substrate; 21, 2;
Reference numeral 2 denotes bent portions bent from both ends of the substrate 20 to the back side of the substrate 20, and these are the portions of the belt 23 that are close to the end to which the buckle 44 is attached, and are bent to fit the waist size of the belt user. Each connecting end 2 which is an end that has been separated and is to be connected to each other.
4 and 25 are formed. Reference numerals 27 and 28 denote insertion ports that open on both sides of the insertion portion 26, and are formed by both side edges of the substrate 20 and both end edges of the bent portions 21 and 22, respectively. 2
9 and 30 are bearing parts protruding from each end of the bending parts 21 and 22 on the insertion part 27 side so as to face each other;
31 and 32 are the insertion ports 27 of the bent parts 21 and 22.
A bearing part 33 protruding from each end of the side so as to face each other is a holding plate pivoted between one bearing part 29 and 30, and a shaft cylinder 34 is integrally provided at one end of the holding plate. The cylinder 34 is fitted between the bearing parts 29 and 30, and is attached to the shaft pin 35 through the bearing parts 29 and 30 and the shaft cylinder 34, and the shaft cylinder 34 has a plurality of engaging pawls 36 protruding from it. The other end of this presser plate 33 is a free end 46 that rotates around the shaft pin 35 as a fulcrum.
The free end 46 is provided with the hooking claw 36 at the position where it bites the deepest into one connecting end 24 of the belt 23 inserted into the insertion portion 26 from the insertion opening 27, that is, it bites completely. A stopper portion 37 is bent and formed so as to abut against the back surface of the substrate 20 when the substrate 20 is rotated to the inserted position.
Reference numeral 38 denotes a presser plate that is pivotally attached between the other bearing parts 31 and 32. A shaft cylinder 39 is integrally provided at one end of the holding plate, and this shaft cylinder 39 is fitted between the bearing parts 31 and 32. and the shaft pin 40 is passed through the shaft cylinder 39, and the shaft cylinder 39 has a plurality of engaging pawls 4.
1 is provided protrudingly, and the other end of this presser plate 38 is a free end 49 that rotates around a shaft pin 40 as a fulcrum,
At this free end 49, a hooking claw 41 is attached to the insertion opening 28.
When the belt 23 inserted into the insertion part 26 is rotated to the position where it bites into the cut-off end 25 of the insert part 26 most deeply, that is, where it bites completely, it hits the shaft cylinder 34 of the presser plate 33 and slightly A stopper part 42 is provided which is shaped so as to curve back. With the connecting ends 24 and 25 connected in this way, if it becomes necessary to adjust the size of the belt 23 again, remove only the engaging claw 41 of the presser plate 38 from the connecting end 25. Rotate the free end 49, pull out the connecting end 25 from the insertion part 26, cut it down to the size to be adjusted, and then insert it into the insertion part 26 so that the engaging claw 41 bites into it. It may be possible to connect them. Reference numeral 43 indicates a portion of the substrate 20 between the bearing portion 29 and the bearing portion 31, and a portion between the bearing portion 30 and the bearing portion 32.
This is a ring piece that is wound around the substrate 20 through the part between them, and the end of the band 23 is passed through it. In addition, when using a particularly thick band 23, a substrate 20' shaped so as to swell slightly toward the front side as shown in FIG. 8 may be used instead of the substrate 20.

[Effect of idea]

Since the present invention is constructed as described above, it is possible to eliminate insufficient biting of the hooking claws into each connecting end of the belt inserted into the back side of the board, and to adjust it according to the waist circumference of the belt user. This has the advantage that each connecting end of the belt that has been separated can be reliably connected.
