Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a carabiner that can be used in various fields such as mountain climbing, temporary construction sites, evacuation sites, and rescue sites.

[Prior art] A conventional carabiner is shown in Fig. 1.
Since the C-shaped connecting rod 2 opens toward the inside, the maximum opening width of the opening/closing rod 1 is narrow, which has the disadvantage that it cannot be used for steel pipes such as temporary equipment.

[Problem that the invention attempts to solve]

The present invention solves these drawbacks, and the technical problem is to provide a carabiner that allows even large-diameter objects such as steel pipes to be passed through and hung by opening the opening/closing rod to the outside.

[Means for solving problems]

One end of the opening/closing rod a is pivotally attached to the base end 10a of the C-shaped connecting rod 10 with a pivot shaft 12 via a spring 11, and the opening/closing rod a is provided so as to be able to be opened and closed both inside and outside. It is provided so as to open against the spring 11, and the tip end is connected to the connecting rod 10 to the outside.
The opening/closing rod a is formed of two opening/closing rod forming members 13 and 14, and the opening/closing rod forming member 13 , 14 are pivotally connected by a pivot shaft 22 via a spring 15 to form the opening/closing rod forming member 1.
3 and 14 are provided so as to be folded outward against the spring 15, the opening/closing rod forming member 13 is opened inward against the spring 11, and the opening/closing rod forming member 14 is folded outward against the spring 15. When you release your hand in this state, the opening/closing rod forming members 13, 14
The return force of the spring 11 is such that the returning force of the springs 11 and 15 causes the spring 11 to return to a straight line, and the tip of the opening/closing rod forming member 14 is disengaged from the engaging portion 10b of the connecting rod 10, opening outward. , 15.

〔Example〕

The carabiner shown in the drawing is egg-shaped and has a large diameter hook 19 on one side and a small diameter hook 20 on the other side for connecting the steel pipe 16 and the rope 17.

The opening/closing rod forming members 13 and 14 shown in the drawings are bent metal plates, and by changing the direction of the opening/closing rod forming members 13 and 14, the end portions are attached to the pivot shaft 22.
A stopper plate 18 is provided on the opening/closing rod forming member 14 side, which also serves as a finger rest and locking on the opening/closing rod forming member 13 side, to prevent the opening/closing rod forming member 14 from being folded inward. are doing.

In the figure, 21 is a spring retaining groove.

[Effect of idea]

Since the present invention is configured as described above, the opening/closing rod a is pushed inward using the pivot shaft 12 as a fulcrum from the locked state shown in FIG. After removing it from the joining part 10b and bending the opening/closing rod forming member 14 outward against the spring 15 as shown by the solid line in FIG.
is returned to its original position by the restoring force of the spring 15, and at the same time the entire opening/closing rod a is opened outward by the restoring force of the spring 11 as shown in the imaginary line, and the tip of this opening/closing rod a and one end of the connecting rod 10 Since a large gap is formed between the connecting rod 10b and the connecting rod 10b, the steel pipe 16 can be inserted through this gap and hooked onto the large diameter portion 19 of the connecting rod 10.

Next, from this state, the opening/closing rod forming member 14 is folded outward against the spring 15, and the spring 1
When the opening/closing rod a is pushed into the connecting rod 10 against the pressure 1 and released, the opening/closing rod forming member 14 returns to its original state, that is, returns to the opening/closing rod forming member 13 in a straight line state, as shown in FIG. The tip of the opening/closing rod forming member 14 is engaged with one end 10a of the connecting rod 10 to form a locked state.

In this case, as shown in FIG. 4, when the opening/closing rod forming member 14 of the opening/closing rod a is folded outward, a gap is formed between the opening/closing rod forming member 14 and the other end 10b of the connecting rod 10. Connecting rod 10 from the gap
The rope 17 can be inserted into the small diameter portion 20 of the rope and hung thereon.

Once the tip of the opening/closing rod a is connected to the other end 1 of the rod 10
Opening/closing lever a by engaging and locking with 0b
It can be used safely because the locking device will not be released unless an external force is applied to push it in.

In this way, the present invention forms the opening/closing rod a with the opening/closing rod forming members 13 and 14, and the opening/closing rod forming member 1
3 and 14 can be folded so that the opening/closing rod a can be opened wide outward and easily hooked onto the steel pipe 16, and at the same time, the opening/closing rod a can be folded into a dogleg shape and the rope 17 can also be hooked thereon. It has excellent practical effects, such as being able to do the following.
