Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention relates to a structure of a handle of cutlery such as a kitchen knife or knife that can also be used as a sheath.

(Prior art) Conventionally, this type of cutlery has been used, for example, in the 1970s.
-There is one described in Publication No. 120153. In the same blade, the base ends of the dorsal and ventral handles are rotatably supported by shafts with respect to the base end of the blade, and in use, the handles overlap each other to form a grip handle, When not in use, the dorsal side of the blade is stored in the dorsal handle, and the cutting edge side of the blade is stored in the ventral handle.

(Problem to be solved by the invention) However, since both handles are simply overlapped when in use, the width of the blade that can be stored in both handles when not in use (the distance between the cutting edge and the back) is limited. teeth,
It must always be narrower than the width of the dorsal stalk plus the width of the ventral stalk. If the width of the sword blade is to be widened, the width of the grip handle must also be widened accordingly, but from the point of view of ease of use, the width of the grip handle cannot be made too wide; There were restrictions on selection.

Therefore, even if the width of the blade is widened, the grip handle does not have to be widened accordingly to maintain ease of use, which in turn widens the range of blade width selection, and allows for the use of cutlery. The present invention is designed to make it easier to use in various situations.

Structure of the invention (means for solving problems) That is, as shown in the drawings of the embodiments described later, the invention consists of the handle parts 2 and 3 on the dorsal and ventral sides of the proximal end 4a of the blade 4. The base end portions 2a, 3a are rotatably supported by shafts 5, 6, and when in use, the handle portions 2, 3 are stacked on top of each other to form a grip handle 1, and when not in use, the back 11 side of the blade 4 is In a cutlery in which the cutting edge 12 side of the blade 4 is stored in the handle part 2 on the dorsal side and in the handle part 3 on the ventral side, both handle parts 2 and 3 are overlapped with each other when in use. The width W2 of the grip handle 1 is made smaller than the widest width W2 on the proximal end 4a side of the sword blade 4, and the handle 3 has a cutting edge storage part that is stored in the handle 2 on the back side in use. 9 is installed protrudingly.

(Function) And the width W2 of the grip handle 1 consisting of both handle parts 2 and 3
Even if a blade edge storage part 9 is provided protruding from the ventral handle part 3 so that a wider blade (width W1) can be stored in both handle parts 2 and 3, this blade storage part 9 cannot be stored when in use. The part 9 can be stored inside the handle part 2 on the back side. Further, in the use state, the width W2 of the grip handle 1 is smaller than the widest width on the proximal end side of the blade 4.

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

The grip handle 1 consists of a dorsal handle part 2 and a ventral handle part 3, whose base ends 2a and 3a are connected to the base end 4a of the blade 4.
In the operating state shown in FIGS. 1 and 2, both handle portions 2 and 3 are overlapped with each other, and their tips 2b and 3b are connected to each other by a stopper frame 7. It is becoming more and more like this.

Inside the handle 2 on the back side are both ends 2a and 2b.
A storage gap 8 is formed between them, and both upper and lower sides of the gap 8 are open (open openings 8a, 8b). Further, a cutting edge storage portion 9 is provided in a protruding manner on the upper side of the handle portion 3 on the ventral side. A storage gap 10 is formed between both ends 3a and 3b of the handle portion 3 including the blade edge storage portion 9, and the lower side of the gap 10 is open (open opening 10a). In the above usage state, the second and third
As shown in the figure, the cutting edge storage section 9 is accommodated in the handle section 2 on the back side through its opening 8b.

In the blade 4, the spine 11 extends linearly from the upper edge of the base end 4a and continues to the tip, and the cutting edge 11 extends from the lower edge of the base end 4a via a step 12a.
2 extends and continues to the tip. The width W1 of this blade 4 (the widest distance between the cutting edge 12 and the back 11 on the proximal end 4a side of the blade 4 shown in FIG. 2) is wider than the width W2 of the grip handle 1 consisting of both handle parts 2 and 3. ing.

Next, when both handles 2 and 3 are rotated from the above-mentioned use state and overlapped with each other as shown in FIGS. 4 to 6, the back 11 side of the blade 4 is inserted into the gap 8 of the handle 2 on the back side While being stored through the opening 8a,
The cutting edge 12 side of the blade 4 is stored in the gap 10 of the handle 3 on the ventral side through its open opening 10a, and becomes unused.

In particular, in this embodiment, as shown in FIGS. 4 to 6, a cutting edge storage part 9 is provided protrudingly from the handle part 3 on the ventral side, so that the width W2 of the grip handle 1 consisting of both handle parts 2 and 3 is Even in the case where the wide blade 4 (width W1) can be stored in the gaps 8 and 10 of both handles 2 and 3, in the usage condition shown in FIGS. can be stored in the gap 8 of the handle 2 on the back side, so even if the width W1 of the blade 4 is increased, there is no need to increase the width W2 of the handle 1 accordingly. W2 can remain narrow and ease of use can be maintained, and the width W1 of the blade 4 can be kept narrow.
The selection range can be widened.

Furthermore, when cutting something on the cutting board, the fingers gripping the handle 1 do not touch the cutting board, making it very easy to use. When the blade 4 is in use, the storage protrusion 9
Since the two handles 2 and 3 are housed in the handle 2, the handles 2 and 3 do not shift laterally relative to each other, making it very easy to use.

Effects of the invention In short, according to the invention, even if the width W1 of the blade 4 is widened, there is no need to increase the width W2 of the grip handle 1 accordingly, and the width W2 of the grip handle 1 can remain narrow. When cutting something on the cutting board in the state of use, the fingers gripping the handle 1 do not touch the cutting board, so ease of use can be maintained, and the range of width W1 of the blade 4 can be widened. I can do it.

Furthermore, since the cutting edge storage section can be stored in the handle when the cutler is in use, the handles do not shift laterally relative to each other, making the knife very easy to use.
