[Action]

 According to the strap stopper according to the present invention, the end portion of the strap is inserted and arranged in the strap insertion hole of the stopper body, and then the strap stator is fitted into the stator fitting through hole to be fixed. By engaging with the main body of the strap, the lower surface of the strap stator sandwiches the portion to be clamped that continues from the tip of the end of the strap between the lower surface of the strap stator and the inner peripheral surface portion of the strap insertion hole that faces it. The end of the strap is firmly fixed and held by the stopper because the tip end of the strap that is inflated to a greater degree than the pinched portion engages with the inner surface of the strap stator. Thus, by connecting both ends of one strap to a common stop, an annular strap can be easily formed.

【Example】

 Embodiments of the present invention will be described below. 1 and 2 are an explanatory perspective view and an explanatory vertical front view, respectively, showing an exploded view of an embodiment of a camera strap stopper according to the present invention. The stopper 10 is composed of a stopper main body 20 having a rectangular parallelepiped shape as a whole and a strap stator 30 combined with the stopper main body 20, both of which are made of resin such as polypropylene. It is a molded product.

In the stopper main body 20, a strap insertion hole 23 having an opening 22 at one end side end face 21 thereof and having a rectangular cross section into which the end S (see FIG. 3) of the strap is inserted is formed. Therefore, the stopper main body 20 is entirely in the shape of a rectangular tube. The width D of the strap insertion hole 23 is a size suitable for positioning the ends S of the strap processed by the stopper 10 in a line, that is, when the diameter of the strap is R, it is approximately 2R. , The height H is large enough to fit the diameter R of the end S of the strap. Then, in this stopper body 20, at one of the peripheral walls, in the example shown in the figure, at a position displaced a little from the center in the length direction of the top wall 25, a rectangular stator fitting through hole is provided in this example. 26 is formed, and the stator fitting through hole 26 faces the bottom surface portion 27 of the strap insertion hole 23.

The strap stator 30 is in the shape of a rectangular parallelepiped that fits into the shape of the stator fitting through hole 26 of the stopper body 20 and is press-fitted into the through hole 26. The strap stator 30 has locking projections 33, 33 that project outward and extend laterally on a front surface 31 facing one end of the stopper body 20 and a rear surface 32 opposite to the front surface 31. Has been formed. An upper surface of the locking projection 33 forms a horizontal locking surface 33A, and a lower surface thereof forms a cam surface 33B formed by an inclined surface that expands outward as it goes upward.

To give concrete examples of the dimensions of the above parts, the thickness t of the stopper main body 20 is, for example, about 0.8 mm, and the stopper body 20 faces the stator fitting through hole 26 in the strap insertion hole 23. The length L of the inner hole portion 28 that is deeper than the bottom surface portion 27 is about 1.5R. Further, in the strap stator 30, the protruding height h of the locking projection 33 from the front surface 31 or the rear surface 32 thereof is, for example, about 0.5 to 1 mm, and the strap stator 30 is fitted in the protruding height h. The height d (see FIG. 3) of the gap between the lower surface 35 and the bottom surface portion 27 is, for example, about 1/4 to 1/2 of R. In the illustrated example, the height g from the upper surface 36 of the strap stator 30 to the locking surface 33A of the locking projection 33 is equal to the thickness t of the upper wall 25 of the stopper body 20. However, this is not essential in the present invention.

The stopper 10 having the above structure is used as follows. That is, both ends S of the strap to be processed are positioned side by side in the strap insertion hole 23 of the stopper body 20 of the stopper 10, and in this state, the strap stator 30 is fixed as shown in FIG. When the strap stator 30 is inserted into the child fitting through hole 26 and press-fitted using the cam surfaces 33B of the locking projections 33, 33, the lower surface 35 of the strap stator 30 is positioned in the inner hole portion 28. With the tip end portion ST of the end portion S of the strap remaining, the pinched portion SH that follows is crushed between the bottom portion 27 facing the lower surface 35 of the strap stator 30.

Then, when the pressure input is released in a state where the locking surface 33 A of the locking projection 33 of the strap stator 30 exceeds the lower surface of the top wall 25 of the stopper body 20, the locking projection 33 of the locking projection 33 is released. The engagement surface 33A is in a state of engaging with the lower surface of the upper surface wall 25 around the stator fitting through hole 26.

In this state, the stopper body 20, the strap stator 30 and the end portion S of the strap are engaged with each other by the locking projections 33 of the strap stator 30 engaging with the stopper body 20. In particular, the clamped portion SH of the end S of the strap is clamped between the strap stator 30 and the bottom surface portion 27 of the strap insertion hole 23 of the stopper body 20. Firmly fixed in the vertical direction. Moreover, the frontmost end portion ST of the end portion S of the strap located in the inner hole portion 28 of the strap insertion hole 23 has a shape which is greatly expanded as compared with the pinched portion SH in accordance with its natural form. As a result, this leading edge ST is brought into engagement with the rear surface 32 of the strap stator 30, whereby the end S of the strap engages the stop 10 in its longitudinal direction, which also adds to this. Then, the end S of the strap is integrally fixed to the stopper 10.

As described above, both ends S of the strap are integrally fixed to the stopper 10, and are eventually connected in a ring shape. Therefore, by inserting the strap into the strap insertion portion of the camera body in advance, it is possible to easily provide the camera body with the ring-shaped strap.

Then, the locking projections 33 of the strap stator 30 are made to be able to release the locking state so that the ends S of the respective straps are released by releasing the locking. Therefore, when a defective portion is generated, it is possible to regenerate and repair it very easily. Even if it is impossible to release the locked state, if the stopper 10 is destroyed, the end S of the strap is not specially processed, so that the strap is prevented from being wasted. It

Various means can be used to make the strap stator 30 releasable in the locked state. For example, the bottom surface of the stopper body 20 facing the through hole 26 for fitting the stator. A releasing device insertion hole is formed in the portion 27 so that the fixing state to the strap is not disturbed, and an appropriate releasing device is inserted through the releasing device insertion hole to remove the locking projections 33, 33. It is also possible to employ a means for pushing the strap stator out of the through hole for fitting the stator by utilizing the flexibility of the locking projection.

Alternatively, the strap stator 30 is formed with a groove that opens on the upper surface thereof so as to extend over the entire width of the strap stator 30, so that the strap stator 30 is provided between the front wall and the rear wall of the strap stator 30. It is assumed that the entire cross section is U-shaped with the groove interposed. In this case, for example, by holding the strap stator by bringing the front surface 31 and the rear surface 32 close to each other with an appropriate holding tool such as tweezers, the front wall and the rear surface wall come close to each other, and thus the locking is performed. Since the protrusions 33, 33 are retracted, they can be easily unlocked.

4 and 5 are perspective views showing modifications of the lower surface 35 of the strap stator 30, respectively. In the example of FIG. 4, the lower surface 35 is formed with the protrusions 36, 36 having cusps that pierce each of the ends S of the strap, and in the example of FIG. 5, the lower surface 35 is A large number of protrusions 37 are formed. As described above, according to the strap stator 30 in which the lower surface 35 is formed with protrusions or irregularities or the lower surface 35 is rough, it is large between the end portion S of the strap and the pinched portion SH. It is preferable because slip resistance is obtained and the connection strength with the end S of the strap is increased.

In the above, the material of the strap is not particularly limited, and straps of various configurations made of appropriate fibers such as polypropylene and nylon can be used, but the lower surface 35 of the strap stator 30 is used. On the other hand, it is preferable to use a structure having a large slip resistance, for example, a strap such as a braid.

According to the camera strap stopper having the above configuration, the following operational effects can be obtained. (1) The strap stator 30 is press-fitted into the stopper main body 20 and locked, so that the ends S of the two straps can be commonly connected to the stopper 10. A ring-shaped strap can be attached to the main body very easily. Moreover, the strap stator 30 clamps the pinched portion SH following the tip end portion ST of the end portion S of the strap so that the swollen tip end portion ST is engaged with the strap stator 30. Therefore, the end S of the strap is firmly connected to the stopper 10. (2) Since the stopper 10 is made of resin, it can be easily manufactured by, for example, a molding method, and the end S of the strap basically does not need to be processed, which is troublesome. Not surprisingly, the cost is low. . (3) Since the connecting portion of the end S of the strap is covered with the stopper 10 having a box shape as a whole, it has a preferable appearance. (4) The end S of the strap is firmly connected to the stopper 10 and the end S of the strap is released by releasing the locked state of the strap stator 30 from the stopper main body 20. So it can be regenerated and repaired. (5) Since the strap stator 30 may be simply press-fitted into the strap insertion hole 23 of the stopper body 20, the work of connecting the ends S of the strap is easy.

Although one embodiment of the present invention has been described above, various modifications can be made in the present invention. For example, the configuration or the manner of engagement of the engagement portion of the strap stator with respect to the stopper body is not particularly limited, and various ones can be used. Further, the forms of the stopper body, the strap insertion hole, the strap insertion hole, and the strap stator are not limited to the examples shown in the figures, and various configurations can be adopted.

The strap stop of the present invention can also be utilized to treat each of the ends of the strap alone, rather than for the purpose of joining the two ends of a strap. In this case, the width of the strap insertion hole of the stopper body is sized to fit the diameter of the end of the strap to be treated. The stopper of the present invention has a function as a slip-out preventing member for the strap insertion portion of the camera body, for example. Further, the strap stopper of the present invention can be applied not only as a strap for a camera but also as a strap stopper for other articles.
