Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a sheath for cutlery such as knives and kitchen knives, and in particular to a sheath consisting of a pair of wooden side plates.

(Prior art) In general, this type of wooden sheath for knives, kitchen knives, etc. has only two side plates that are glued and fixed, so during long-term use, the wood expands. Both side plates sometimes separated from each other due to shrinkage.

(Problems to be solved by this invention) Therefore, this invention solves the problem that the two side plates constituting the sheath become separated from each other due to the expansion and contraction of the wood, making it impossible to use it for a long period of time. It is meant to solve problems.

Structure of the invention (means to solve the problem) In order to solve the above problems, this invention
A pair of wooden side plates 4 are assembled to form the sheath body 3, and a fitting recess 6 is formed in an annular shape on the outer periphery of the proximal end of the sheath body 3. A tightening member 8 is attached to prevent the side plates 4 from separating from each other.

(Function) When the sheath is configured as described above, the tightening member 8 irremovably tightens and fixes the side plates 4 of the sheath body 3 to each other. Furthermore, the tightening member 8 is installed within the fitting recess 6, so that the tightening member 8 does not come off from the sheath body 3.

(Example) An example in which the present invention is embodied in a knife sheath will be described below with reference to FIGS. 1 to 3.

1 is the handle of the knife, and 2 is the body attached to the same handle 1. 3 is a sheath body formed by adhesively fixing a pair of wooden side plates 4, and is provided with a storage hole 5 for storing the body 2. Reference numeral 6 indicates a fitting recess provided at the proximal end of the sheath body 3 over the entire outer circumference of the sheath body 3, and reference numeral 7 indicates a pair of transparent fitting recesses provided in the fitting recess 6 approximately at the widthwise center of both side plates 4. It is a latch hole.

Reference numeral 8 denotes a cylindrical plastic tightening member fitted into the fitting recess 6 of the sheath body 3, and is adapted to irremovably tighten and fix the both side plates 4 from the outside thereof. . Reference numeral 9 denotes a pair of latching protrusions provided on both inner surfaces of the tightening member 8, which engage into both latching holes 7 when the tightening member 8 is attached to the fitting recess 6 of the sheath body 3. It is becoming more and more common. Note that the length of the latching protrusion 9 is the same as the length of the latching hole 7, or slightly shorter than that. Reference numeral 10 is a mesh-like anti-slip formed on the outer circumferential surface of the tightening member 8 to prevent the hand from slipping when gripping the sheath body 3.

Now, when manufacturing a knife sheath configured as described above, first the both side plates 4 are adhesively fixed to each other to form the sheath body 3, and then the tightening member 8 is inserted into the fitting recess 6 of the sheath body 3. Attach to. At this time, the tightening member 8 is only attached to the sheath body 3 by engaging both of its inner latching protrusions 9 into the latching hole 7 of the fitting recess 6. In this case, normally both latching protrusions 9 do not protrude into the storage hole 5 of the sheath body 3.

In this way, the pair of side plates 4 of the sheath body 3 are irremovably fixed by the tightening member 8. Therefore, unlike the case where both side plates 4 are simply fixed with adhesive, both side plates 4 will not separate from each other even if used for a long period of time.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the following arbitrary changes are possible.

For example, in the embodiment described above, the anti-slip member 10 of the tightening member 8 is formed in a net shape, but as shown in FIGS.
It may also consist of

Furthermore, the tightening member 8 is not limited to being made of plastic.
It may be made of rubber or metal, and in the case of metal, a cut may be made on the back or ventral side of the tightening member 8.

Note that the present invention is applicable not only to knife sheaths but also to sheaths for other cutlery such as kitchen knives.

Effects of the invention As detailed above, the present invention prevents the two side plates of the sheath body from separating from each other due to the expansion and contraction of the wood, making it possible to use the sheath for a long period of time. At the same time, it exhibits an excellent effect in that the tightening members that make the both side plates cannot be removed will not come off inadvertently.
