Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention relates to a structure that prevents the blade from slipping out when stored in the sheath of cutlery such as kitchen knives and knives.

(Problems to be solved by conventional techniques and inventions) Conventionally, this type of sheath has been used, for example, in
-There is one described in Publication No. 138099. In this scabbard, the stopper that locks the jaw when the blade is stored is rotatably attached to the outside of the scabbard body.
The entire stopper member protruded from the sheath body, giving it a poor appearance.

Therefore, if the stop member is accommodated within the sheath body, this drawback can be solved, but if the stop member is configured to rotate, there is a problem that the sheath main body becomes larger by the space for housing the stop member.

Therefore, if the stop member were made to be able to slide along the sheath body, this problem would be considerably solved, but the rim of the blade insertion opening where the jaw of the blade is inserted and removed is narrow, and the stop member cannot be operated easily. Therefore, it is very difficult to support the stop member so that it can slide facing only this lip edge, and if the stop member is made large enough, the disadvantage of the protruding part of the housing part will be solved. Can not.

Structure of the invention (means for solving the problem) The present invention has been made in view of this problem, and as shown in the drawings of the embodiment described later, the jaw 8a of the blade 8 is inserted into and removed from the blade entrance 3. A guide portion 4 is formed by bending from the ventral mouth edge 3a toward the distal end side of the sheath body 1, and the guide portion 4 has a jaw portion 8 of the blade 8 when stored.
The flexible body 6 is movably supported so that it can take a position where it locks and a position where it releases the lock.

(Function) Then, insert the blade 8 into the sheath body 1 at its insertion port 3.
When going in and out, the flexible body 6 is moved to open the space between the ventral side edges 3a of the insertion port 3. When the blade 8 is housed in the sheath body 1, the jaw 8a of the blade 8 is located inside the guide part 4. After the blade 8 is stored, the flexible body 6 is moved and bent along the guide part 4 to close the ventral mouth edge 3a of the insertion port 3. By being locked, the blade 8 can be prevented from slipping out of the sheath body 1 during storage.

(Example) An example of the present invention will be described below with reference to the drawings.

As shown in FIG.
As shown in the figure, when the side plates 2 are overlapped, the sheath body 1
The dorsal side of the proximal end is notched to form a stepped portion 1a, and a blade insertion opening 3 is formed in the entire proximal end surface. From the mouth edge 3a on the ventral side of the stepped portion 1a of the inlet 3, the sheath body 1
As shown in FIG.
It is formed with a slight bend. An opening 5 is formed in the abdomen 1b of the sheath body 1 in correspondence with the guide groove 4.

Further, a flexible body 6 (in this embodiment, a flexible body 6 having parallel grooves 7 as shown in FIG. 1) is fitted into both the guide grooves 4 so as to be movable along the guide grooves 4. An integrally formed operation knob 6a is exposed through the opening 5 so as to be externally operable. By moving the operating knob 6a, the flexible body 6 can be moved to a position where the ventral mouth edge 3a of the blade insertion opening 3 is opened as shown in FIGS. As shown, it is possible to take a position that closes this area.

Now, as shown in FIG. 5, when inserting or removing the knife blade 8 from the sheath body 1 through the insertion opening 3, position the operating knob 6a of the flexible body 6 on the tip side of the opening 5, and then Open the space between the ventral mouth edges 3a of No.3. When the blade 8 of the knife is stored in the sheath body 1, the mouth 9a of the handle 9 of the knife stops at the insertion opening 3 and rests on the step 1a, and the jaw 8a of the blade 8
is located inside the guide groove 4.

After storing the blade 8, when the operating knob 6a of the flexible body 6 is moved toward the proximal end of the opening 5 as shown in FIG. 6, the flexible body 6 moves along the guide groove 4.
It is bent at 90 degrees to close the space between the ventral edges 3a of the entrance 3. Therefore, the jaw 8a of the blade 8 is connected to this flexible body 6.
This prevents the blade 8 from slipping out of the sheath body 1 when it is stored.

Although not shown, in the above embodiment,
The corner 1c of the sheath body 1 shown in FIGS. 3 to 6 may also be opened to form a continuous gap between the ventral mouth edge 3a of the insertion port 3 and the opening 5, so that the entire flexible body 6 can be seen from the outside. good.

Effects of the Invention In short, according to the sheath according to the present invention, when the blade 8 is stored, the bending flexible body 6 is used to lock the jaw 8a of the blade 8, thereby preventing the blade 8 from slipping out. Therefore, even if the flexible body 6 is made large to some extent for ease of operation, the blade 8 can be moved by the flexible body 6 at the ventral mouth edge 3a of the narrow insertion port 3.
The locking operation of the jaw portion 8a can be performed, and a part of the flexible body 6 other than the portion that performs the locking operation can be attached to the sheath body 1.
It can be fitted along this line without protruding from the surface.
