Description

[Detailed explanation of the invention] Purpose of the invention (industrial application field) This invention relates to a sheath for cutlery in which the body is inserted from the mouth side, and the sheath does not fall out from the body when it is fitted into the body of the knife. It concerns a sheath made like this.

(Prior art) As a sheath for this type of cutlery, the
There is one shown in Publication No. 131174. This scabbard is the 6th ~
As shown in FIG. 8, a plurality of fastening pieces 23,
24, and these clamping pieces 23, 2
4 are arranged so as to be out of phase with each other in the length direction of the sheath. And these clips 2
Between 3 and 24 is an insertion hole 25 for inserting the blade body,
Its width 25a is made slightly narrower than the thickness of the blade body.

(Problem to be solved by the invention) However, the sheath of the above conventional example has the hooking pieces 23,
24 are lined up so that they are out of phase with each other in the length direction of the sheath, and the spacing between the clamping pieces 23 and 24 is made slightly narrower than the thickness of the blade body, so that the insertion hole 2
When inserting the body of the knife into 5, the tip of the knife gets caught on the clamping pieces 23 and 24, or protrudes outward from between the clamping pieces 23 and 23 or between the clamping pieces 24 and 24,
There was a problem that the clamping pieces 23 and 24 were damaged by the tip of the knife.

Structure of the device (means for solving the problem) In order to solve the above problem, this device has one side plate 4 of the pair of side plates 3 and 4 whose base end is at least one of the dorsal part 5 and the abdominal part 6. It is connected to the other side plate 3 so that the tip thereof is free, and is composed of clamping pieces 7 and 8 that can elastically clamp the body 1 of the cutlery in cooperation with the other side plate 3. Clamping piece 7,
A configuration is adopted in which separating parts 7a, 7b, 8a, and 8b are formed on the mouth O side of the opening 8 to widen the distance between this and the side plate 3.

(Function) In the sheath of this invention, the body of the cutlery is clamped and held by the clamping piece, and is held in such a way that it cannot easily slip out of the sheath.

(Example) Hereinafter, an example that embodies this idea will be described.
This will be explained according to Figure 3.

As shown in FIG. 1, the sheath that is fitted onto the body 1 of the cutter is made of synthetic resin and consists of a pair of side plates 3 and 4. 5 and 6 are the back and abdomen of the side plates 3 and 4, and the tip of the back 5 (left end in Figure 1)
is curved downward and connected to the tip of the abdomen 6.

Reference numerals 7 and 8 denote a pair of dorsal side clamping pieces and ventral side clamping pieces whose base ends are fixed to the dorsal part 5 and abdomen 6 and whose tips are free, and the other side plate 4
and cooperates with the side plate 3 to form a blade body 1.
It is designed to be able to be clipped elastically. These clamping pieces 7 protrude toward the abdomen 6, and the ventral clamping pieces 8 protrude toward the back 5, and are arranged alternately in the front-rear direction of the sheath. In particular, as shown in FIG. 3, bent parts 7a and 8a are formed on the side of the opening O of the sheath among the two clamping pieces 7 and 8, respectively, as separating parts to widen the distance from the side plate 3. A space between the bent portions 7a, 8a and the side plate 3 is an allowance portion 9 for facilitating insertion of the blade 1 of the cutter.

Reference numeral 10 denotes a storage hole formed between the side plates 3 and 4, into which the blade 1 of the knife can be inserted. Note that holes 11 are provided in the side plate 3 at positions corresponding to both the clamping pieces 7 and 8.

Now, when storing the body 1 of the cutlery in the sheath configured as described above, the tip of the knife body 1 is inserted from the mouth O side of the sheath.

Also, among the two clamping pieces 7 and 8, bent portions 7a and 8a are provided on the side of the opening O of the sheath to widen the distance from the side plate 3.
Because of this provision, when inserting the body 1 into the insertion hole 9, the body 1 can be smoothly fitted without being caught by both the clamping pieces 7 and 8, and both clamping pieces 7 and 8 will not be damaged.

When fitted into the sheath in this manner, the sheath is attached to the knife body 1 in a state in which the body 1 is elastically clamped by the two clamping pieces 7, 8 and the side plate 3. After installation,
Since the body 1 is thus clamped and held by both clamping pieces 7 and 8, it not only does not easily fall out of the sheath, but also does not rattle within the sheath.

Furthermore, the sheath includes a side plate 3 and dorsal and ventral clamping pieces 7,
Since it has a simple structure consisting of 8 and 8, it is easy to mold it when integrally formed with synthetic resin.

Note that this invention is not limited to the above-mentioned embodiment. For example, as shown in FIG. Alternatively, although not shown, the notches 7b and 8b may be formed in an arc shape.

In addition, as shown in FIG. 5a, two dorsal clamping pieces 7
are integrally formed into a continuous mountain shape, and the ventral side clamping piece 8 is made to protrude to a position corresponding to the trough.
As shown in FIG. b, only the dorsal side clamping piece 7 may be provided, or only the ventral side clamping piece 8 (not shown) may be provided.

Further, in the embodiment shown in FIGS. 1 to 3, two clamping pieces 7 and 8 are provided, but one or three or more clamping pieces 7 and 8 may be provided. It may be provided so as to protrude obliquely in the direction.

Effects of the invention As detailed above, the sheath of this invention has a simple structure and is easy to manufacture, and it also prevents the body from getting caught on the clamping piece or damaging the clamping piece when inserting the body of the knife. It has the effect of being able to be fitted smoothly without coming off, and furthermore, being able to reliably prevent it from falling off after being fitted.
