Description

[Detailed description of the invention] (Field of industrial application) This invention relates to knives with sheaths such as paring knives and kitchen knives.

(Prior art) A knife with a sheath has a locking mechanism that prevents the two from easily separating when the sword body is housed in the sheath, and also allows the two to separate with a predetermined force when in use. However, it may be dangerous to grasp the sheath body and the handle to separate them, depending on the strength of the attachment, and it is recommended to grasp the handle with one hand so that the work can be done with one hand. Various means have been proposed for removing the sheath body in this state.

For example, one with a pressing protrusion on the side of the sheath body (Utility Model Publication No. 57-40052), one with a pressing projection on the top of the sheath body (Utility Model Publication No. 58-23338), and one with a sheath pusher on the top of the handle. Equipped with a moving piece (Jetko Sho 59-33336
No.) is known.

(Problems to be solved by the invention) In the conventional one-handed handling described above, in which the sheath body is provided with a pressing protrusion, when the sheath body is detached from the sword body and removed from the sword body, the finger is There is a risk of injury as it will be protruding from the position of the sword body. Further, the above-mentioned device in which the sheath extrusion sliding piece is provided at the top of the handle has the disadvantage that if the sliding piece moves during work, it will interfere with the work.

(Means for Solving the Problems) Therefore, the present invention is designed to prevent the sheath pushing member provided on the handle from moving during work. In other words, the proposed sheathed knife consists of a sword body attached to a handle and a sheath body into which the sword body is inserted and housed, and a part of the sword body side that is housed in the sheath body and the interior of the sheath body correspond to each other. In a knife with a sheath provided with a mating concavo-convex portion, a sliding sheath pushing member is attached to the side surface of the sheath-side end of the handle, and a stopper for preventing detachment and a retreating storage corresponding to the forward protruding position of the sheath pushing member are attached. A click generating portion corresponding to the hour position is provided.

Therefore, if the push-out member is pushed forward with the fingers while the handle is being gripped, the fitting concave and convex portions will be disengaged from each other and the sheath body will be separated from the sword body. After the sheath is removed and the pressing member is returned to its original position,
The pressing member is lightly secured by the click portion, so that it does not protrude forward without permission.

(Example) Next, an embodiment of the present invention will be described based on the drawings.

The proposed sheathed knife is composed of a main body having a sword body 3 and a sheath body 1, and the main body is composed of a handle 2 and a sword body 3 attached to a top plate. A click protrusion in which two dovetail grooves 4 are bored at the sheath side end of the handle 2, a stopper protrusion 5 is provided at the sheath side end between the dovetail grooves 4, and the slope is low and gentle on the caudal side. 6 each. A separately formed extruded body 7 has protrusions 8 on its lower surface that fit tightly into the dovetail grooves 4, and protrusions 9 are provided between the protrusions 8 on the rear portion. Further, a fitting protrusion 10 is provided on the side surface of the base of the sword body 3, and a recess (not shown) corresponding to the fitting protrusion 10 is provided in the sheath body 1.

When the sword body 3 is inserted and stored in the sheath body 1, the fitting protrusion 10 fits into the fitting recess in the sheath body 1, and the two become one, so that the sheath body 1 does not easily come off. It's getting old. When using the knife, if you push the extrusion body 7 forward with your fingers while grasping the handle 2,
When the sheath body 1 is pushed out from the handle side by the extrusion body 7, the fitting with the fitting protrusion 10 and the recess is released, and the sheath body 1 is removed from the sword body 3. As shown in FIG. As shown in A, the protrusion 9 returns beyond the click protrusion 6 and is prevented from moving forward by the click protrusion 6. During use, the extrusion body 7 protrudes forward and obstructs the use of the knife. There is no such thing as that.

The present invention is not limited to the above-mentioned embodiments, and for example, the click generating part is not a combination of the click protrusions 6 and 9 as described above, but a metal plate is embedded in the rear part of the extrusion member, and the click protrusions are Any structure may be used as long as the extrusion member can be easily fixed thereto, such as by embedding a magnet in the portion provided with 6.

(Effects of the invention) As described above, the present invention is a knife with a sheath, in which a stopper and a click part are provided on the sheath extrusion member attached to the handle, and the sheath body is detached by the extrusion member, and The click portion prevents unnecessary movement of the extrusion member, so that the extrusion member does not get in the way during use.

Claims (1)

[Scope of utility model registration request] It consists of a sword body attached to a handle and a sheath body into which the sword body is inserted and housed, and fitting uneven parts are provided at corresponding positions between a part of the sword body side that is housed in the sheath body and the inside of the sheath body. In a knife with a sheath, a sliding sheath pushing member is attached to the side surface of the sheath side end of the handle, and a stopper for preventing detachment corresponds to the forward protruding position of the sheath pushing member, and a click is generated corresponding to the backward storage position. A knife with a sheath.
