Description

[Detailed description of the invention] This invention relates to a strap stopper used when attaching a strap to a portable object such as a camera or a portable radio, and was filed in 1983 by the applicant.
-This is an improvement to No. 51137.

In other words, the strap fastener of the previous application was configured so that the upper left corners of a pair of opposing locking plates of the opening-closing body were pivotally supported above the locking hook opening of the fastener main body so as to be able to swing freely so that the opening of the locking hook could be opened and closed, and when the opening of the locking hook was closed, the locking protrusions provided on the right side of the inner side of each locking plate of the opening-closing body, approximately in the vertical center, engage with circular locking holes drilled on the opposite side of the locking hook opening of the fastener main body.

However, when the opening of the locking hook is closed, it is necessary to lock the locking protrusion of the opening/closing body in the locking hole of the stopper body, and the opening/closing part of the opening/closing body that comes into contact with the tip of the locking hook. Due to the acute angle formed between the line connecting the pivot part of the body and the line connecting the pivot part of the opening/closing body and the locking part of the locking protrusion to the locking hole, the stopper When the locking hook of the main body is locked to the attachment ring of a portable object and the portable object is carried, and the attachment ring of the portable object strongly hits the opening/closing part of the opening/closing body, the locking protrusion of the opening/closing body will close to the stop body. The opening/closing body is easy to swing when pulled out from the locking hole,
This has the drawback that the locking hook opening of the main body of the stopper is opened and comes off from the attachment ring of the portable object.

Therefore, the purpose of this invention is to solve the above-mentioned problems, and the gist is that the upper and lower parts of the board are provided with insertion holes for connecting straps and locking rings for attaching portable objects. A locking hook is provided, and a notch is provided on the opposite side of the locking hook opening at approximately the center of the substrate in the vertical direction. On the opening side of the locking hook, the closed side proximal end of a pair of opposing locking plates of the opening/closing body having a substantially U-shape in plan is connected to the locking hook provided inside the open side tip of one of the locking plates. The protrusion is locked in the notch, and the opening/closing part provided downward at the proximal end on the closed side of each locking plate is brought into contact with the tip of the locking hook to open and close the locking hook opening. This is due to the fact that it is pivotally supported so that it can swing freely.

An embodiment of this invention will be described below with reference to the drawings.

The strap stopper of this invention is connected to both ends of a strap S as shown in the figure, and is latched to mounting rings R attached to both ends of a portable object (not shown) such as a camera or a portable radio. The stopper body A is made of metal and is attached to the stopper main body A, and the opening/closing body B is made of plastic and is pivotally supported by the stopper main body A and opens and closes an opening of a locking hook (described later).

The stopper main body A has a substrate 1 having a substantially inverted equilateral triangular shape when viewed from the front.
An insertion hole 2 for connecting the strap S is bored in the upper part of the base plate 1, and a locking hook 3 having a substantially J-shaped front face for locking the mounting ring R is formed in the lower part of the board 1, and an opening 4 is provided on one side of the locking hook 3. It will be missing so that it can be installed. Furthermore, a shaft hole 5 is bored in one side of the opening 4 between the insertion hole 2 and the locking hook 3 of the substrate 1, and a notch is formed in the other side opposite to the shaft hole 5. 6.

Further, the opening/closing body B has a substantially U-shape in plan, and a connecting piece 8 is provided at the left end of a pair of opposing locking plates 7, so that the locking plates 7 are connected to each other by connecting the locking plates 7 to each other. Install them in series to the extent that they are slightly wider than the plate thickness of main body A,
Further, at the left end of each locking plate 7, an opening/closing part 10 is provided at the tip thereof to protrude downward and has a recess 9 that comes into contact with the tip of the locking hook 3. Furthermore, a shaft pin 11 is provided protruding near the left end of one of the locking plates 7, and a locking protrusion 12 is provided at the inner right end of the other locking plate 7.

Then, the shaft pins 11 of each locking plate 7 of the opening/closing body B are inserted into the shaft hole 5 of the base plate 1 of the stopper main body A, so that the locking protrusion 12 is locked in the notch 6 at the time of closing, and the opening/closing part 10 It is swingably supported so that the tip recess 9 of the locking hook 3 comes into contact with the tip of the locking hook 3 and the opening 4 of the locking hook 3 is opened and closed.

In this device, while constructed as described above, both ends of the strap S are inserted through the insertion holes 2 of the fastener body A to connect them, and then the opening/closing body B is swung clockwise around the pivot pin 11 to open the opening 4 of the fastening hook 3 of the fastener body A, and then the fastening hook 3 of the fastener body A is engaged with the mounting ring R of the portable object from the opening 4 side, and then the opening/closing body B is swung counterclockwise to close the opening 4 of the fastening hook 3, which makes it easy to attach the strap S with one hand while supporting the portable object with the other hand.

Moreover, when the opening 4 of the locking hook 3 of the stopper body A is closed, the locking protrusion 12 of the opening/closing body B is locked in the notch 6 of the stopper main body A, and the tip of the locking hook 3 is A line connecting the opening/closing part 10 of the opening/closing body B that comes into contact with the pivot support by the shaft pin 11 of the opening/closing body B, and the pivot part of the opening/closing body B and the locking part of the locking protrusion 12 to the notch 6 are connected. Since the angle formed by the connecting line is not an acute angle as in the conventional case but a substantially right angle, even if the attachment ring R of the portable object strongly hits the opening/closing part 10 of the opening/closing body B while carrying it, Dynamically, the locking protrusion 12 of the opening/closing body B is pulled out of the notch 6 of the stopper body A, making it difficult for the opening/closing body B to swing, compared to the case where the locking protrusion 12 of the opening/closing body B has an acute angle. It is possible to reliably prevent the portable object from coming off the attachment ring R due to the opening 4 of the hook 3 being opened.

As explained above, by using the stopper of this invention, it is not only possible to support a portable object with one hand while attaching the strap with the other hand, but also to easily attach the strap to the portable object while carrying it. Various effects can be obtained, such as being able to reliably prevent it from coming off, and furthermore, simplifying the structure and providing it at low cost.
