CLASS 69: Cutting tools.

-The subject of the present invention is a safety handle for cutting tools (knives u. s. w.) or cut - or stabbing weapons, in which a locking of the blade both in the usable condition, as well as when not in use by turning one in the hollow handle lying pipe takes place, at the same time the advantage is achieved that the knife or When not in use, the weapon is only about half the length of when it is ready for use.

The essence of the invention is shown in more detail on the accompanying drawing, for example on a dagger knife, and explained in the following. The blade α is loosely inserted in a hollow handle in a corresponding slot b ^l . A hollow tube c is rotatably mounted in the handle reaching up to the tang or the pressure α ^{ί of the blade;} the latter has in its bottom c ¹ a slot c " ² of such length and width that the blade α can fall through it or can be pushed through it.

Fig. Ι shows the knife in a usable state, the blade α sticks with the blunt tang or the pressure a ^l in the slot or incision b ^{l of} the handle b. The pipe c is gedächt so rotated, the slot DAF c ¹ c ¹ of the bottom across a ¹ or b ¹ applies, as shown in Fig. 4 can be seen. Any kind of retention may be appropriate to prevent accidental twisting of the tube c. The blade-α is now established, since α rests firmly in the deep slot b ^l and cannot push itself into the tube c through the slot c ² lying transversely to a ^1. When not in use, the blade α can be brought into the tube c by the fact that the latter z. B. by means of the ring c ^{1 'seated in button c 3} rotates by 90 ° until slot c ² coincides with slot b ¹ (FIGS. 2 and 5).

Now it is easy to push the blade a into the tube c or to let it fall into it, whereby the position of the blade α can be identified by letting it slide in two guides b ² lying in the tube b. If the two sleeves b and c are then rotated again by 90 °, the two slots b ¹ and c ^{2 are} again positioned across each other (FIGS. 3 and 6), the blade α is thereby determined for non-use and cannot fall back from inside the tube c. To bring the sword again in the position of use, it has b and c again so as to rotate against each other by 90 ^0, that the slots £>'and c ² coincide and can pass through the blade passing through but repeated twisting of b and c can be determined to each other for use, as Fig. ι shows.

The shape of the handle b can be chosen at will and z. B., as in Fig. 7, hexagonal or, as in Fig. 8, oval; conversely, the tube c can be angular or oval in cross-section and the handle b round, only it is necessary that two overlapping or intersecting slots once the

Let the blade through and then fix it. The rotation of the slots can be adjusted accordingly the object in question are effected, as well as the retention of the Blade or rotatable parts are chosen according to the purpose of the tool or weapon can be.

To avoid damaging the blade tip, the edges of the slots or they themselves can be covered with or made of soft material in the handle and tube exist.

Claims (1)

Patent claim: A safety handle for cutting tools, cutting and stabbing weapons, characterized in that the blade (a ) falls back into a tube (c) rotatable in the hollow handle (b ) when not in use, a slot (c ) made in the bottom (c ¹ ) of the latter ² ) in one position, when the latter crosses the slot opening (b ¹ ) of the handle (b ) holding the blade (a), it locks the blade, in the other position when both slots ( b'c ¹ ) are above each other, step forward or backward.
