Description

[Detailed description of the invention] Technical field This invention relates to a sheath for a paring knife, etc.

Conventionally, as shown in FIG. 11, the sheath of a paring knife or the like is provided with a locking protrusion 30 on the inside of the proximal end of the sheath body 11, so that when the blade of the knife is attached to the sheath body 11, the blade part is locked. There was one that was configured to be locked with a locking protrusion 30 to prevent the blade from separating from the sheath body 11.

However, if the sheath main body 11 is configured in this way,
When attaching and detaching the knife blade to and from the sheath body 11, the blade strongly rubs the surface of the locking protrusion 30 of the sheath body 11 with almost its entire length, so the knife is pulled strongly when attaching and detaching. Not only was this necessary, but the locking protrusion 30 came into contact with the cutting edge of the blade when the knife was inserted and was scraped, resulting in the inconvenience that the scrapes accumulated in the sheath body 11 and became unhygienic.

Purpose of the invention The purpose of this invention is to eliminate the above-mentioned disadvantages, to make the blade part easy to attach and remove, and to prevent the blade part from coming off naturally because it is locked inside after it is inserted. Furthermore, it is an object of the present invention to provide a sheath for a paring knife, etc., which can be used hygienically without causing scrapes from the clamping piece to come out inside when the blade is attached and detached.

Structure of the device In order to achieve the above object, the sheath body is composed of a pair of side plates that cover the entire blade and a blade insertion groove between the side plates. At least one clamping piece is formed that protrudes into the insertion groove at a position on the dorsal side of the cutting edge of the blade and holds the tip of the blade of a paring knife or the like.

Embodiment Hereinafter, an embodiment in which this invention is embodied in a sheath of a paring knife will be described in detail with reference to the drawings.

1 is a paring knife, 2 is the handle of the knife 1, and 3 is the blade. Reference numeral 4 denotes the main body of the sheath according to the present invention into which the blade portion 3 is inserted, which includes a pair of side plates 4a, 4b and both side plates integrally formed of synthetic resin material, as shown in Figs. It is constituted by a blade insertion groove 5 between 4a and 4b. Reference numeral 6 denotes a finger hook protruding from the proximal end of one side plate 4a of the sheath body 4, and has a half-flange shape extending in a direction perpendicular to the longitudinal direction of the sheath body 4.

Reference numeral 7 designates water drain holes provided through the tips of the side plates 4a and 4b, three of which are arranged in parallel from the tip to the base. The upper edge of the drain hole 7 extends obliquely with respect to the lower edge, and the vertical width of the drain hole 7 increases toward the proximal end. Note that 7b is a bridge formed between the drain holes 7.

Reference numeral 8 designates two pairs of clipping pieces having rectangular cross-sections that protrude from the bridging portion 7b into the blade insertion groove 5 on the inner surfaces of the respective side plates 4a and 4b and are opposed to each other. When completely inserted into the main body 4, both clamping pieces 8 are arranged so as to clamp the blade portion 3 at a position on the dorsal side of the cutting edge 3a.

Now, if the blade part 3 of the knife 1 is inserted into the sheath body 4 configured as described above, the blade part 3 will be inserted into the sheath body 4.
Since the blade part 3 is clamped by the clamping pieces 8 protruding from the side plates 4a and 4b inside, the blade part 3 is attached to the sheath body 4.
There is no natural departure from it.

In addition, since the clamping pieces 8 are provided at the tips of the side plates 4a and 4b, when the blade part 3 of the knife 1 is attached to and detached from the sheath body 4, only the tip of the blade part 3 is attached to the clamping pieces 8. held by. That is, when the blade part 3 is almost completely housed in the sheath body 4 when it is inserted, and when it is removed, the blade part 3 is
The clamping piece 8 only clamps the blade part 3 at the initial stage of pulling it out from the sheath body 4, and is immediately released. Therefore, the force of the clamping piece 8 is only slightly applied to the blade part 3, and the force of the blade part 3 against the sheath body 4 is small.
The force required for insertion and removal is extremely small.

Furthermore, since only the tip of the blade portion 3 contacts the clamping piece 8 within the sheath body 4, the amount of wear on the clamping piece 8 due to attachment and detachment of the blade portion 3 is small.
Further, there is no risk that the entire blade portion 3 will be damaged by the clamping piece 8. Moreover, when the blade part 3 is stored in the sheath body 4, the clamping piece 8 is located at the dorsal side of the cutting edge 3a of the blade part 3.
a does not come into contact with the clamping piece 8, and the clamping piece 8 is not scraped by the cutting edge 3a.

Furthermore, since the only part of the blade portion 3 that has plastic residue is a small portion of the tip, it is not noticeable and does not cause any discomfort to the user's appearance.

In addition, after using the paring knife, if you wash it and store it in the sheath body 4, the water attached to the blade part 3 will escape from the drain hole 7 of the sheath body 4, so after washing the knife blade part 3, There is no need to wipe off the water each time.

5 to 8 show other examples of the clamping piece 8 of this invention.

That is, the clamping piece 8 shown in FIG. 5 has a sharp tip, and the clip in FIG. 6 has a half-arc shape in cross section. In addition, FIG. 7 shows one side plate 4b, 4a.
A clamping piece 8 is provided only at the top. Furthermore, if the clamping piece 8 is formed to have a trapezoidal cross section as shown in FIG. 8, the attachment and detachment of the blade portion 3 to and from the sheath body 4 can be performed even more smoothly.

In addition, with this invention, the drain holes 7 of the side plates 4a and 4b
As shown in FIG. 9, even if the sheath body 4 is formed to extend in the longitudinal direction, the effect will not change in any way. In this case as well, the clamping piece 8 is provided at the bridge portion 7b formed between the drain holes 7.

10a to 10c show another example of the sheath body 4. FIG. That is, one or both of the side plates 4a and 4b [Fig. 10a] or both [Fig. 10b] are formed separately so that they can be assembled to the sheath body 4, thereby facilitating the manufacture of the sheath. be. It is of course possible to provide drain holes 7 in the side plates 4a and 4b constructed in this way, as shown in FIG. 10c.

Note that this invention is not limited to the above embodiments, and for example, each side plate 4a, 4b
The number of clamping pieces 8 provided on the knife is 1 or 3 or more, and knives other than paring knives, machetes,
Any changes can be made without departing from the spirit of this invention, such as applying it to the sheath body of a cutlery such as a kitchen knife.

Effects As detailed above, this device consists of a pair of side plates that cover the entire blade and a blade insertion groove between the two side plates, and the sheath is inserted inside the tip of the side plates. By forming at least one clamping piece that protrudes into the insertion groove at a position on the dorsal side of the cutting edge of the blade portion and clamps the tip of the blade portion of the paring knife, etc., the blade portion of the paring knife etc. can be attached and detached. It is easy to insert, the blade part does not fall off naturally after it is inserted, there is no risk of scratching the entire blade part, and in particular, the clamping piece is inside the tip of the side plate. It is formed at a position dorsal to the cutting edge of the blade to be inserted, so when the knife is inserted, the clamping piece will not come into contact with the cutting edge and be scraped, and shavings will not accumulate inside the sheath body as in conventional cases. Therefore, it is a practically preferable idea because it can be used hygienically.
