CLASS 47d. GROUP

The subject of the invention is an innovation in snap hooks, which aims a bending up of the bent carabiner leg and the unwanted swinging out of the resulting from this bending up straight karabiner leg respectively. to prevent automatic opening of the snap hook.

The innovation is there. in essence in it,

that the snap hook in a partial

ίο the frame is mounted so that it can swing is and in the position in which the legs of the snap hook from the Frame sides are enclosed, is held in place by a nose through which the Bracket slides away into the frame during its swinging movement.

In Fig. Ι and 2 of the drawing, the snap hook is in front and rear views and in the

Figs. 3 and 4
CD of FIG. 1

in

Sections to AB and shown.

FIG. 5 shows a representation analogous to FIG. 3 with the bracket open.

Fig. 6 is another embodiment.

The actual snap hook, b is constructed in the usual way and is pivotably mounted at its lower end by means of the pin g in a frame c so that it can assume the swung-out position shown in FIG. 5 or the position shown in FIGS. 1 to 3, in which it is enclosed by the frame c , which is excluded on the side corresponding to the carabiner curve.

In the first position (Fig. 5) the snap hook can be used in the usual way or. A ring can be inserted into the same by the inward swinging of the movable leg b , while in the latter position (Fig. 1 to 3) both karabiner legs a, b are encompassed by the frame c and bending of the karabiner legs is completely excluded. Even . an accidental inward bending of the swingable leg b could not cause the ring held in the carabiner to slip away, since the latter is unable to reach the point of the carabiner opened by the inward bending of the movable bracket b.

The sides of the frame c corresponding to the karabiner legs are connected to one another by webs d, f which lie in the rear delimitation plane of the frame c and prevent the frame sides from bending out.

In the position in which the carabiner a, b rests on the webs d, f and is tightly enclosed by the frame c, it is secured in that a nose h is arranged at a suitable point on the frame c , over which the carabiner leg b slides away when settling into the rest position.

In order to be able to push the karabiner leg b inwards when the karabiner hook swings out of the frame, it is provided with a handle k at a suitable point.

The nose through which the snap hook is held in the frame, can also be used anywhere else in the

Frame are arranged in the form of a small contact surface, over which the in the Frame swinging carabiners slides away and over which he can only use a certain exertion can be brought back again.

To make the snap hook lockable, one of the frame sides, such as this is indicated in Fig. 6, a small ίο lock can be arranged, the bolt in in the locked state penetrates the carbine shank.

Claims (3)

Patent Claims: I. Snap hook with device for Prevention of automatic opening, characterized by a snap hook enclosing frame, open at its arch, in which the snap hook can swing at its lower end is stored and in which he is held in the position of use by noses, over which he is in his Swing motion slides into the frame. 2. embodiment of the bracket according to claim 1, characterized in that the nose holding the snap hook in the position of use is arranged at a point on the frame corresponding to the swinging snap hook is and that this leg carries a handle to swing the karabiner leg inward can. 3. Device according to claim 1, characterized by the arrangement of a Lock on the frame in such a way that the lock bolt holds the carabiner in the locked position. 1 sheet of drawings.
