Description

The present invention relates to a snap hook in which a hook member is provided at an opening of the hook, and more particularly to a snap hook suitable for carrying and carrying a fishing accessory having a ring part or a closed loop part.

As shown in FIG. 5, for example, as shown in FIG. 5, the main body 51 has a main body 51 formed on one end 51a side on the hook 52 and the other end 51b side on the other side. The terminal is formed of a round rod made of stainless steel or aluminum alloy that is bent into a shape facing the tip of the hook 52 at a certain interval, and the other end 51b closes the opening 53 of the hook 52. A detachment preventing member 54 of the type is attached by being urged by a torsion spring or the like so as to come into pressure contact with the front end surface of the hook from the inside of the hook 52.

This type of snap hook is originally made as a rope hanging bracket for hanging climbing ropes, tent ropes, etc., but it can be attached to the belt loop of trousers, rucksacks, bags, bags, etc. As shown in FIG. 5B, the key ring 56 that hangs the key 55 is hooked on the hook 52 and used as a key holder for carrying the key 55.

However, as shown in FIG. 5 (a), the inward opening type stopper 54 that closes the opening of the hook 52 is inwardly contacted with a part of the body or clothes from the outside as shown in FIG. 5 (b). Then, the opening 53 of the hook 52 is unintentionally opened, and the key ring 56 latched on the hook 52 may come out from the opening 53, and the key 55 may fall off.

In order to prevent the opening of the hook from being opened unintentionally due to the inward opening type locking member being opened, there are two different ways to open the locking member that closes the opening of the hook. A dual-action safety snap hook that requires action has been proposed (see Patent Document 1), but the double-action type is not only cumbersome to operate, but also has a structure. There is a drawback that it is complicated and the manufacturing cost increases.

Further, the snap hook of FIG. 5 pushes and opens the detachment prevention member 54 inward when attaching or detaching the snap hook to the belt loop of a trouser, a bag, a metal ring of a bag or the like, as shown in FIG. The opening 53 of the hook 52 is opened. At this time, there is a possibility that an article such as a key ring 56 hung on the hook 52 may fall out of the opening 53 of the hook 52, and the double action type safety snap as described above. The same is true for hooks.

By the way, for fishing, for example, as shown in FIG. 6, the snap fitting 63 used to connect the luer 62 to the line (fishing line) 61 in a replaceable manner, the line thread and Harris of the line, Small accessories such as Sarkan, Yorimodoshi, etc. used to connect the two are required, so these various accessories are placed in fishing vest pockets or a case with a lid such as a tackle case that fits inside the waist bag. It is common to carry.

However, during fishing, it is troublesome to carry out an operation of taking a tackle case containing small metal fittings into and out of a pocket or a bag or opening and closing the lid of the tackle case. Especially when you are fishing in the water, casting a lure or fly in the shallow waters of rivers, seas, lakes, etc., there is no place for the casting rod (fishing rod). It is necessary to open and close the tackle case lid with both hands while holding it, and also to take out the small metal fittings in the tackle case while holding both the casting rod and the tackle case in hand. At the same time, there was a risk of dropping the tackle case into the water.

Therefore, the present inventor provided the fishing vest with the snap fitting 63 having the ring portion or the closed loop portions 64 and 65 as shown in FIG. Although it was intended to be hooked on a fishing hook by hanging on a snap hook that can be attached to a belt ring of a D-ring or trousers, many commercially available snap hooks provide strength that can be used as rope hooks. Therefore, as shown in FIG. 5, since the main body 51 including the hook 52 is formed of a thick round rod, the small-sized snap fitting 63 as shown in FIG.

Further, as described above, the snap hook of FIG. 5 unintentionally opens the opening 53 of the hook 52 when a part of the body, clothes, or the like is pressed against the slip-off preventing member 54 that closes the opening 53 of the hook 52. As a result, there is a possibility that the article hung on the hook 52 from the opening 53 falls off.

Further, since the opening portion 53 of the hook 52 that holds the article is opened when the snap hook of FIG. 5 is attached to and detached from a belt loop of a pants, the article that is hooked on the hook 52 from the opening 53. May fall off. In particular, a light and small-sized article made of a thin wire such as the snap fitting 63 shown in FIG. There is a risk of falling off the opening 53 of the hook 52.

Further, when an article hung on the hook 52 is removed from the hook, the anti-slip member 54 that closes the opening 53 of the hook 52 is pushed with the fingertip from the outside to open the inside and at the same time the state is maintained. In this case, the article held on the hook 52 must be picked up with the fingertips and pulled out from the opening 53 of the hook 52, but it is difficult to perform such an operation with only one finger. During the operation, there is a risk of dropping an article picked up with a fingertip, and in particular, a small-sized article is highly likely.

The part 4 is provided with an outwardly-opening-type anti-slip member 5 that is urged so as to be pressed against the tip end surface from the outside of the hook F2.

An inwardly opening-type locking member 3 provided in the opening 2 of the hook F1 includes a fixed end 3b that is rotatably fixed to the shank portion 7 of the hook F2 by a shaft pin 8, and the hook from the inside of the hook F1. It is formed of a rod made of stainless steel or aluminum alloy having a free end 3a pressed against the surface of the tip, and is attached so as to turn toward the tip of the hook F1 by a torsion spring (not shown). It is energized. The anti-slip member 3 is not limited to a rod, and is bent into a hairpin shape or a loop shape, such as the “hairpin-shaped claw portion 4” described in FIGS. 1 and 5 of Patent Document 1. It may be made of a stainless steel wire.

An outwardly opening-type locking member 5 provided in the opening 4 of the hook F2 is in pressure contact with the fixed end 5b fixed to the shank portion 6 of the hook F1 from the outside of the hook F2 to the tip end surface of the hook. It is formed by a thin leaf spring L having a free end 5a.

The thin leaf spring L is formed into a strip-like spring having a width approximately equal to the thickness of the snap hook body 1 by stainless spring steel (SUS301, SUS304, or SUS304L) having a thickness of about 0.2 to 0.4 mm. The end 5b is formed into a curl shape that is curled and bent inward, and is fitted into a slot 9 formed in the shank portion 6 of the hook F1 and fixed, so that the free end 5a can be moved from the outside of the hook F2. The hook is biased so as to come into pressure contact with the front end surface of the hook. Note that the fixed end 5 b of the thin leaf spring L is fixed to the groove wall of the slit groove 9 with a metal adhesive in order to prevent falling off from the slot groove 9.

A chamfered portion 10 is formed at the front end portion of the hook F2 by stepping off the surface portion where the free end 5a of the thin plate spring L is pressed. Further, the hook F2 has a tip surface formed into a rounded convex curved surface, and a surface of the chamfered portion 10 formed at the tip portion is formed into a smooth surface by mirror polishing. The thin plate spring L is such that the end portion of the free end 5a pressed against the surface of the chamfered portion 10 formed at the tip end portion of the hook F2 is bent outward, and the end portion and the chamfered portion 10 of the hook F2 A clearance C is formed between the two.

For example, as shown in FIG. 4, the snap hook configured as described above is hung on the belt loop 21 by hooking one hook F <b> 1 of the S-shaped hook forming the main body 1 on the belt loop 21 of the trousers. In addition to being attached to the state, a fishing accessory such as a snap fitting 31 is hooked and used on the other hook F2 of the S-shaped hook. The snap fitting 31 is a commercially available product having two large and small closed loop portions 32 and 33 that can be opened and closed by a thin stainless steel wire, and the luer is connected to the line in a replaceable manner in the same manner as the snap fitting 63 of FIG. It is used for cases.

When the snap fitting 31 is hooked on the hook F2, the free spring of the thin leaf spring L (prevention member 5) that holds the snap fitting 31 with the fingertip and presses the closed loop portion 32 against the surface of the tip of the hook F is free. If it is hooked on the terminal portion of the end 5a and pulled toward the fixed end 5b, it can be easily hooked. Further, since the end portion of the free end 5a of the thin leaf spring L is bent outward and a clearance C is formed between the end portion and the tip end surface of the hook F, the closed loop portion of the snap fitting 31 is formed. 32 can be easily and reliably hooked.

When removing the snap fitting 31 latched on the hook F2 from the hook F2, hold the snap fitting 31 with a fingertip and push the closed loop portion 32 against the free end 5a of the thin plate spring L from the inside. If it is pulled and moved toward the end of the free end 5a, it can be easily removed.

Further, the tip surface of the hook F2 is formed into a rounded convex curved surface, and the surface of the chamfered portion 10 of the hook F2 to which the free end 5a of the thin plate spring L is pressed is formed into a smooth surface by mirror polishing. Therefore, even if the thin leaf spring L has a strong urging force, the closed loop portion 32 of the snap fitting 31 is inserted between the distal end portion of the hook F2 and the free end 5a of the thin leaf spring L. Thus, it can be easily pulled and moved in the direction of the end of the free end 5a. Moreover, since the snap hook is supported by the belt loop 21 that holds the hook F1, the closed loop portion 32 of the snap fitting 31 is pulled and moved toward the end of the free end 5a of the thin plate spring L using only one hand. Can do.

Further, since the snap hook is attached to the belt loop 21 by the hook F1, there is no possibility that the snap fitting 31 hooked on the hook F2 will drop off when the snap hook is attached to or detached from the belt loop 21. Further, since the detachment prevention member 5 provided in the opening of the hook F2 is of an outward opening type, there is no possibility that a part of the body or clothes are pressed against the outside from the outside to be unintentionally pushed open.

Further, if the chamfered portion 10 formed by scraping the surface portion is formed at the tip of the hook F2 to which the free end 5a of the stopper member 5 formed by the thin plate spring L is pressed, the thin plate spring L Even if the end portion of the free end 5a is bent outward, the anti-separation member 5 made of the thin plate spring L is prevented from being pushed outward by other objects being caught on the end portion. Therefore, there is almost no possibility that an article such as the snap fitting 31 latched on the hook F2 will come off the hook F2.

  The present invention hangs snap fittings used for fishing, small metal fittings such as Sarkan, Yorimodoshi on metal rings such as D-rings provided on fishing vests and waist bags, belt loops of trousers, etc. A snap hook suitable for a portable application can be provided.
