Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stopper used to connect a string such as a strap to a carried item.
[0002]
[Prior art]
A strap attached to a camera or other portable item is either a hook attached to the end of the strap or an O-shaped or D-shaped snap ring in which a metal wire is rolled up at least once in an annular shape to further provide springiness. Is hooked in a hole formed in the carrying item, and the carrying item and the strap are connected.
[0003]
The snap ring stopper is simpler in structure than the hook stopper, but must be connected to the hole formed in the carrying item while opening against its own springiness. Therefore, operability is bad.
[0004]
On the other hand, the hook stopper having good operability requires a biasing member that opens and closes the opening of the hook so that the hook does not come off from the carrying item during carrying. Such a stopper is described in Patent Document 1.
[0005]
[Patent Document 1]
Figures 3 and 4 of Japanese Utility Model Publication No. 6-36608
However, the hook (hanging body 6 in the above publication) is formed of a thick flat metal that is difficult to be deformed, and between the urging member (the holding body 2 in the above publication) and the hook that opens and closes the opening of the hook. It is necessary to incorporate a coil spring (spring 12 in the above publication) that biases the biasing member in the direction of closing the opening of the hook.
[0007]
FIG. 8 shows a stopper having a structure that does not require the incorporation of such a coil spring. As shown in FIG. 8 (a), this stopper includes a hook 1 formed of a thick flat metal that is difficult to deform, an upper piece 2 and a lower piece 3 on one side 4 and is a resin-molded biasing member. 8, the biasing member 5 is connected to the arm portion 6 of the hook 1, and the opening side 7 of the biasing member 5 is connected to the arm portion 6 of the hook 1 as shown in FIG. It is attached to pinch.
[0008]
In this conventional configuration, as shown in FIG. 8C, the biasing member 5 is rotated with respect to the hook 1 against the elasticity imparted between the upper piece 2 and the lower piece 3, When the tip 8 of the hook 1 in the opened state is engaged with a hole (not shown) of the carrying item and the hand is released from the biasing member 5, the biasing member 5 is opened by the elasticity of itself. It returns to the posture of FIG.
[0009]
[Problems to be solved by the invention]
Although the fastener of FIG. 8 can achieve a reduction in the number of parts, the following problems remain.
[0010]
In the assembly process, it is difficult to assemble and attach the arm 1 of the hook 1 while opening the open side 7 of the biasing member 5 having strong elasticity so that the opening of the hook 1 is not opened carelessly. When the elasticity of the urging member 5 is weakened, the opening of the hook 1 opens carelessly.
[0011]
Further, since the flat metal is punched into the hook 1, for example, the plate thickness dimension and the width W of the tip 8 need to have a certain dimension in order to obtain the required tensile strength.
[0012]
