In a pocket knife, the individual tools move from the folded to the unfolded state by rotating against the pressure of a spring about an axis transverse to the longitudinal central axis of the knife. It can be changed to In the open position, the tool is prevented from further rotation by a stopper. If the forces applied to the tool during use act to force the tool against the stop, the tool will not snap closed. However, when using a pocket knife tool, if a force is applied to the tool that causes it to rotate in the closing direction, the tool may snap shut and there is a risk of injury.

るいはばねを操作しなければならない。 Locking devices for folding knife blades are known in which the blade is locked in the open position by an additional lever or spring. However, this known locking device requires additional construction costs.
Furthermore, in order to close it again, a lever or a spring must be operated in addition to the blade.

る。 Furthermore, a device for locking the tool of a pocket knife is known from Japanese Utility Model Publication No. 33-15600. This locking device locks the tool in the open position and prevents the tool from snapping closed when the pocket knife is in use. However, re-closing the tool requires an additional action to pull the tool out in the direction of the central longitudinal axis of the pocket knife.

The problem of the present invention is that after the force has ceased to act on the tool, the tool can be returned to its original position without any additional manipulation, since in this position the tool can be rotated.
It is an object of the present invention to provide a tool locking mechanism for a pocket knife that can be folded for its closure and automatically returns to its original position.

The object is to provide a tool rotatable about an axis and a spring disposed within the pocket knife, with means for engaging the tool and the spring with each other when a force is applied to the tool, and wherein said axis is A locking mechanism for a pocket knife having an elongated, oval, or slit-shaped opening formed in the tool to prevent the tool from snapping closed due to forces acting on the tool during use. wherein the longitudinal center axis of the opening formed in the tool is not parallel to the longitudinal center axis of the pocket knife;
The solution is that the protrusion of the spring presses against the edge of the tool so that the tool returns to its original position again after the force has ceased to act on the tool.

This locking mechanism prevents the tool from snapping unexpectedly, even when forces are applied from various directions, so there is no risk of injury. Moreover, since the tool automatically returns to the unlocked position when no force is applied to the tool, no additional operation of the locking mechanism is required. Furthermore, this locking mechanism is simpler in construction than known ones. If the tool of the pocket knife is in particular designed as a screwdriver, it is avoided that the tool snaps shut when a force is applied in the direction of the longitudinal central axis, and there is no risk of injury.
以下、添付図面に基づいて本考案の実施例を詳

Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings.

果として手を傷つけることになる。 FIG. 1 shows a pocket knife 1 and a screwdriver 2 as a tool in the open state. When turning a screw, if the force applied to the screwdriver is not directed along the longitudinal center axis of the screwdriver, the screwdriver may snap shut unexpectedly, resulting in injury to the hand.

用時のロツクのために、ねじ回しが切欠き６と突
起７を、ばねが突起８と切欠き９を備えている。 FIG. 2 shows a portion of the pocket knife and the screwdriver 2 in an open position, with the side wall of the pocket knife removed. The screwdriver 2 is rotatably provided around a shaft 3, and an opening 4 in the screwdriver into which the shaft 3 is inserted has an oval shape. A spring 5 along the length of the pocket knife holds the screwdriver in its closed or open position. However, the force exerted on the screwdriver 2 by the spring 5 is too small to prevent it from snapping closed during use of the screwdriver. Also,
The force exerted by the spring must not be too great to facilitate closure. Therefore, for locking during use, the screwdriver is provided with a notch 6 and a protrusion 7, and the spring is provided with a protrusion 8 and a notch 9.

ので、付加的なロツク解除操作が不要である。 When the screwdriver is pressed against the screw in the open state when using the screwdriver, the protrusion 7 of the screwdriver engages with the notch 9 of the spring 5, and the protrusion 8 engages with the notch 6, as shown in FIG. interlock. The central longitudinal axis of the elongated, oval or slit-shaped opening 4 formed in the screwdriver is inclined with respect to the central longitudinal axis of the pocket knife. Thereby, when a force in the direction of the longitudinal axis of the screwdriver is applied to the screwdriver, the lip 10 of its rear end 11 is pressed against the lip 12 of the projection 13 of the spring 5. Therefore, after the force is no longer acting on the screwdriver 2, i.e. after the pressure on the screw is released, the screwdriver 2 is automatically returned to its original position, i.e. the position shown in FIG. . In this way, no additional unlocking operation is required since the tool automatically returns to its original position.
