"Prior Art and its Problems" The present applicant has already proposed this type of strap stopper in Japanese Utility Model Publication No. 35410/1982 and Japanese Utility Model Application No. 10662/1989. The former places a resistance plate in the middle of stacked straps, and presses one strap against the resistance plate by the pressurizing part of a locking pawl that rotates around its axis, while the latter uses the locking force of the strap. In order to make the straps stronger, a low-drag plate is not provided, and the straps are bent in an overlapping state by the pressurizing part of the retaining pawl and pushed out from the strap bulging hole. However, with these fasteners, when tension is applied to the strap, force is applied from the radial direction to the rotation shaft of the pawl, and this force causes the rotation shaft to disengage from the shaft hole, causing the locking force of the pawl to disappear. It was later discovered that, in the worst case scenario, there is a danger that the belongings carried may fall.
Even if there is no such danger, force is always applied to the pawl from only one side in the radial direction, so the support strength must be increased.

``Summary of the Invention'' The present invention positions the pressurizing part of the stopper in the middle of the overlapping straps, and when the stopper is folded down, the pressurizing part separates the upper and lower straps, and the main body of the stopper is moved. It is characterized in that by pushing the strap out into the bulging hole, independent locking forces are applied to the upper and lower straps. Furthermore, this pressurized part becomes perpendicular to the strap once the retaining pawl is brought down from the raised position.
It rotates further and then stops. In this manner, when the pressurized portion crosses the state where it is perpendicular to the strap and then stops, a locking force is exerted against forces applied to the strap in both directions.

"Embodiments of the Invention" The present invention will be described below with reference to illustrated embodiments. This stopper includes a stopper main body 10 and a stopper claw 20. The stopper main body 10 is made of a synthetic resin material or a metal material, and integrally has an upper surface portion 11, a lower surface portion 12, and both side surface portions 13 to form a strap insertion opening 14 in the shape of a flat rectangular tube. This insertion opening 14 is large enough to allow the overlapping straps S to be inserted almost immediately. Rotation fulcrum holes 15 for the retaining pawl 20 are bored in both side surfaces 13 of the stopper body 10 so as to be located on the same axis, and rotation fulcrum holes 15 are formed in the upper surface 11 and the lower surface 12. Strap bulging holes 16, 17 across the front and back
is formed.

The retaining pawl 20 is made of a high-strength member such as a metal material, and includes a pair of swinging arms 22 on both sides, and a tilting operation section 2 provided at the outer end of the pair of swinging arms 22.
1, and a pressurizing section 25 provided at the inner end of the pair of swinging arms 22. Flat pressurized part 2
5 has a rotating shaft 26 protruding from both ends thereof, and this rotating shaft 26 is unrotatably fitted into a square hole 24 bored at the inner end of the swinging arm 22. There is.
The rotation shaft 26 allows the stopper claw 20 inserted into the rotation support hole 15 of the stopper main body 10 to be raised and lowered. The plate-shaped pressurizing part 25, which does not rotate with respect to the swinging arm 22, is located diagonally between the upper and lower straps S when the stopper claw 20 is folded down, and the strap S is inserted into the strap expansion hole 16 of the stopper body 10, When pushed out to the 17 side and the pawl 20 is raised, it is formed so as to be positioned parallel to the upper and lower straps S. That is, when the retaining pawl 20 is brought down from the raised state, the pressurizing part 25 once makes the strap S at a right angle, and then stops in the further rotated state shown in FIG. 3. Note that 27 is a retaining pawl 2 formed on the upper surface portion 11.
This is a finger hook recess for the raising/lowering operation part 21 of No. 0.

Therefore, the main stopper with the above structure has the stopper claw 20.
When the straps are raised as shown in FIG. 4, the plate-shaped pressurizing part 25 is located parallel to the stacked straps S, so the contact pressure or frictional force between the pressurizing part 25 and the straps S is small. Therefore, the length can be adjusted by freely sliding the upper and lower straps S relative to each other. On the other hand, when the retaining claw 20 is tilted down as shown in FIG. 3 after adjusting the length, the pressurizing part 25 is positioned diagonally between the straps S, and the upper and lower straps S are moved toward the bulging holes 16 and 17, respectively. In order to push the strap out, a large frictional force acts between the strap S and the end walls of the bulging holes 16 and 17, and thus the strap S is locked to the stopper main body 10. The important point is that at this time, since forces are applied to the pressurized portion 25 almost equally from the upper and lower straps, no radial force is exerted to remove the rotation shaft 26 from the rotation fulcrum hole 15. In other words, the strap S can be stopped with extremely stable locking force.

The size of the bulging holes 16 and 17 in the front-rear direction, that is, the length l in FIG. It shall be determined that the In addition, this stopper has a pressurized part 25 located diagonally between the straps S.
On the other hand, the strap is used so that a tension T is applied from the strap S in the direction shown by the arrow in FIG. 3 due to the weight of the carried item. This is because rotational force in the locking direction is applied to the pawl 20 via the pressurizing portion 25.

Further, in the present invention, when the retaining pawl 20 is in the folded state, the retaining pawl 25 is perpendicular to the strap S and then stopped in a further rotated state, so that the retaining pawl 25 is diagonal to the strap S. Even when a force in the opposite direction to the tension T is applied to the strap S, the retaining pawl 20 does not easily rotate. That is, if an attempt is made to rotate the pawl 20 with a force in the opposite direction to the tension T, the pressurized part 25 must be rotated to a state perpendicular to the strap S, but in order to do this, it is necessary to You have to push out the strap S that is in place. A large force is required to spread the strap S in this way, and such force is not applied under normal usage conditions. Therefore, there is no risk that the strap S will be unlatched inadvertently.

``Effects of the Invention'' In summary, the strap stopper according to the present invention is such that the pressurized part of the stopper is located between the overlapping upper and lower straps, and when the stopper is pushed down, the upper and lower straps are separated and the stopper is removed. Since it acts to push out the strap into the bulging hole of the main body, it is possible to provide independent locking force to the upper and lower straps with the stopper main body, and to securely lock the strap. In addition, when the retaining pawl is folded down, the pressurized part becomes perpendicular to the upper and lower straps, and then rotates further so that it is located diagonally between the upper and lower straps, so it resists forces in both directions applied to the strap. , the strap can be securely locked. Furthermore, since the upper and lower straps apply force almost equally to this pressurized portion, there is no risk that the retaining claw will fall off from the stopper body due to the force exerted on the retaining claw from the strap.
