Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an opening / closing member at an opening of a hook, and the opening / closing member is opened and closed by an urging force.
So-called snap hooks , especially used for mooring dogs
About hooks . 2. Description of the Related Art A hook 1 which is generally called a snap hook and is used for anchoring a dog or the like, as shown in FIG. And an opening / closing bracket 4 rotatably mounted on a fulcrum 5 provided on a base 3 of the hook body 2 for opening and closing the hook. [0003] A spring 6 is fitted between the hook body 2 and the opening / closing member 4, and the tip of the spring 6 is pressed against the tip of the hook body 2 by the urging force of the spring 6.
The opening of the hook body 2 is closed. 5, the opening of the hook main body 2 can be opened by pushing the outer edge of the opening / closing fitting 4 inward against the biasing force of the spring 6. [0004] This type of hook can easily open the opening by pushing the front part 7 of the opening / closing fitting 4 inward, while the front part 7 of the opening / closing fitting 4 can be easily opened.
When an inward force is applied to the opening / closing fitting 4 due to an object hitting the opening, the opening of the hook body 2 may be unexpectedly opened. In particular, when using this type of hook for mooring dogs,
There was a problem that the hook suddenly came off and the dog escaped. Therefore, an object of the present invention is to provide a hook whose opening is difficult to open. [0006] In order to solve the above-mentioned problems, a mooring hook for a dog or the like according to the present invention is provided with a hook body having a bent distal end and a base rotatable around the hook body.
It has an opening on the front side of the hook attached to the
It consists of a closing fitting for opening and closing the opening of the click body, on the hook body, narrowing the opening of the hook body toward the tip from the base, and the state in which the outer edge has closed the closing bracket
An opening preventing portion exposed from the opening of the opening / closing bracket is formed, and the opening / closing bracket is formed of a metal fitting along both side surfaces of the hook body and the opening preventing section and partially covering them, and is covered by the opening / closing metal fitting. the opening preventing portion of the hook body, closing fittings provide opportunities roots hole in the direction of rotation, the spring hole
A penetrating spring pin is provided on the opening / closing bracket, and
One end of the spring is locked to the pin, the spring is inserted into the spring hole in a compressed state, and the tip of the outer edge of the opening / closing fitting is pressed against the tip of the hook body by the urging force. [0007] Even if an object hits the front side of the opening with the hook with the opening / closing member closed, the opening / closing member hits a limited narrow portion at the tip of the opening / closing member without the opening prevention portion, and the opening / closing member is inwardly strong. Unless pressed, the opening of the hook body is not opened. In addition, even when the opening of the hook body is open, the opening of the hook body is narrow, so that the thing that opened the opening of the hook body is in the way, and the hook is prevented from coming off from the hooked object. You. Then, when opening the opening / closing bracket, it is sufficient to pinch and rotate only the opening / closing bracket. Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a hook 11 according to the present invention comprises a hook body 12 having a bent tip and an opening / closing fitting 13 for opening and closing an opening 14 of the hook body 12. The opening / closing fitting 13 is attached rotatably about a fulcrum 16 provided on a base 15 of the hook body 12. The hook body 12 is provided with an opening preventing portion 17 for narrowing the opening 14 of the hook body 12 from the base portion 15 toward the tip. As shown in FIG. 2A, outer edges 21, which are both side edges of the front portion 19 of the opening preventing portion 17, are formed along the outer edge 22 of the opening / closing member 13 in a state where the opening / closing member 13 is closed. . In addition, in a state where the opening / closing fitting 13 is opened, as shown in FIG.
7 overlaps with the opening / closing member 13, and the outer edge 21 of the opening preventing portion 17 protrudes more outward than the outer edge 22 of the opening / closing member 13. The opening / closing bracket 13 is shown in FIGS.
(B) As shown in FIG.
It is composed of two metal fittings along both sides of 7 and partially covering them. The opening / closing member 13 is rotatably connected to an opening preventing portion 17 at a fulcrum 16, and an opening 14 of the hook body 12 is formed.
The outer edges 22 are respectively formed on the front side where there is. As described above, along these outer edges 22, the opening prevention portions 1
7 are formed. In addition, the opening and closing bracket 13
Covers a part of the opening 14, and two metal fittings constituting the opening / closing metal fitting 13 are the tip of the outer edge 22,
4 are connected by a front part 18 provided at a certain position. The opening / closing fitting 13 is connected to the hook body 12 by the front portion 18.
And the opening 14 of the hook body 12 is closed.
The front portion 18 has an opening 1 when the opening / closing bracket 13 is opened.
4 so that the opening 14 is sufficiently opened. FIG. 4 shows another example of the opening and closing fitting 13.
As shown in FIG. 3, the plate-like body is bent at the back surface 27 of the hook body 12, and the plate-like body is arranged along both side surfaces of the hook body 12 and the opening preventing portion 17. This is similar to the opening / closing fitting 13 shown in FIG.
8 are provided, and are attached to the hook body 12 and the opening prevention portion 17. In addition, the opening / closing member 13 is connected to the opening preventing portion 17 at a fulcrum 16 to form an outer edge 22. If the tip of the outer edge 22 can contact the tip of the hook body 12, The present invention is not limited to this, and any open / close fitting can be employed. The closure of the opening of the hook body 12 is shown in FIG.
As shown in (a), the tip of the outer edge of the opening / closing fitting 13 is
This is performed by pressing the tip of the hook body 12 by the urging force. As means for applying this biasing force,
A spring such as a wound spring can be used. This spring 24 is shown in FIG.
As shown in FIG. 3, the opening / closing bracket 13 is
Is provided with a long spring hole 23 in the direction in which it rotates, and is inserted in a compressed state therein. Outer edge 21 of opening prevention unit 17
One end of the spring hole 23 remote from the
And one end of the spring 24 is locked by the spring locking portion 25. The spring pin 2 penetrating through the spring hole 23
6 is fixed to the opening / closing bracket 13 and the spring pin 26 is provided.
The other end of the spring 24 is locked. The opening 14 of the hook body 12 is
As shown in FIG. 2 (b), the opening and closing of the opening 14 is effected by pinching and rotating only the opening / closing member 13, and by closing the opening / closing member 13. The opening and closing of the opening of the hook main body 12 is not limited to the above-described method, and any method can be adopted as long as the opening and closing work of the opening and closing fitting 13 can be performed. According to the present invention, even when an object hits the opening side of the hook, the opening / closing fitting has a strong inward force against the limited narrow portion of the tip of the opening / closing fitting without the opening preventing portion. Unless pressed, the opening of the hook body is not opened. On the other hand, the opening of the hook main body can be opened by grasping the opening / closing fitting and rotating only the opening / closing fitting. Therefore, even if this hook is used for anchoring a dog or the like, the opening of the hook main body is not opened depending on a sudden situation, and it is possible to prevent the hook from coming off unexpectedly and the dog from escaping.
