Abstract

(57) [Summary] [Purpose] When the knife is placed horizontally on a horizontal surface, the entire length of the handle is in contact with the horizontal surface, and at the same time most of the cutting edge is in contact with the horizontal surface, so that your hand etc. can directly touch the cutting edge. This prevents the risk of injury due to the knife rotating, causing injury, or the knife falling from the countertop, etc. [Structure] The handle is formed to become gradually thinner toward the blade, and the cross section of the handle is tapered downward.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a kitchen knife.

0002 In this specification, "knife" includes ordinary kitchen knives and knives. Ru. Regarding the vertical relationship, the back side of the blade, that is, the upper side in Figure 1 is called the upper side. The lower side is referred to as the bottom. Also, "blade" refers to the entire metal part of a regular kitchen knife. In particular, when referring only to the cutting part of the blade, it is used as the cutting edge, and when referring to the tip of the blade, it is used as the cutting edge. Let's say ``first''.

0003

[Conventional technology]

If you place a conventional knife on its side on a horizontal surface such as a stove or countertop, the following will occur. It will be in one of two states.

0004 stomach. The entire length of the handle touches the horizontal surface, and the entire blade is suspended above the horizontal surface. Ru.

[0005] B. Only the end of the handle closest to the blade and the tip touch the horizontal surface, and most of the handle and the blade Most of it will be floating above the horizontal surface.

[0006] In case A above, there is a risk of injury if your hand touches the floating edge of the blade. Ta.

[0007] In addition, in case B, in addition to the same danger as in case A above, the knife is likely to rotate. If your hand hits the handle, the knife may rotate, causing injury or causing the knife to hit the countertop. There was also the danger of falling from objects.

[0008] The purpose of this invention is to provide a kitchen knife that completely eliminates the above-mentioned risks.

[0009]

[Problem that the idea aims to solve]

This invention was devised to achieve the above purpose, and the pattern was By using this structure, most of the cutting edge can be brought into contact with the horizontal surface. It was completed based on this knowledge.

0010

[Means to solve the problem]

The knife created by this idea has a handle that gradually becomes thinner towards the blade. In both cases, the cross section is tapered downward.

[0011]

[Effect]

The knife created by this idea has a handle that gradually becomes thinner towards the blade. In addition, its cross section is tapered downward, so if it is placed horizontally on a horizontal surface, In this case, the entire length of the handle is in contact with the horizontal surface, and at the same time most of the cutting edge is in contact with the horizontal surface.

0012

【Example】

An embodiment of this invention will be described below with reference to the drawings.

[0013] The illustrated knife is a butcher knife, which is shown in (B), (C), and (D) in Figure 1. As shown in the cross-sectional shape, the cross-sectional shape of the handle (1) is so-called egg-shaped with roundness throughout. The handle (1) is gradually tapered towards the blade (2). Its cross section is tapered downward.

[0014] The dimensions of each part shown in FIGS. 1 and 2 are as follows.

[0015] The length L1 of the entire knife is 295 mm, the length L2 of the handle (1) is 112 mm, and the top and bottom of the blade (2) The maximum length L3 in the direction is 41 mm. The cross-sectional dimension of the handle (1) is far from the blade (2) The maximum width W1 of the end (3) is 18.5 mm, and the maximum length H1 in the vertical direction is 24 mm. , the maximum width W2 of the end (4) near the blade (2) is 16.5 mm, and the maximum length in the vertical direction The height H2 is 20 mm.

[0016] The blade (2) and handle (1) are fixed by any known appropriate method. In this example , the handle (1) is divided into two plates (1a) and (1b) of the same shape, and is formed at the base of the blade (2). Sandwich the inserted part (8) from both sides between these two plates (1a) and (1b), and The blade (2) and handle (1) are fixed by tightening with rivets (9).

[0017] When the knife formed in this way is placed on a horizontal surface, it will turn out as shown in Figures 3 and 4. , the handle (1) is in contact with the horizontal surface over its entire length, and at the same time most of the cutting edge (5) is in contact with the horizontal surface. do. At this time, the blade (2) is tilted with respect to the horizontal plane. cutting tip (6) and The base (7) of the cutting edge (5) is floating above the horizontal surface, but the amount of floating is small and this There is no risk of injury from touching these parts. Also, the top surface (10) of the handle (1) is round. Therefore, when the knife is placed on a horizontal surface with the top surface (10) of the handle (1) facing down, The knife will not fall over and stand with the blade (2) pointing upwards.

[0018] The degree of taper and downward taper of the handle (1) should be determined by taking into account the shape of the knife blade (2). It is determined. Also, the length of the cutting edge (5) in contact with the horizontal surface varies depending on the shape of the cutting edge (2). It's coming. In the case of the meat cleaver in the above example, the cutting tip (6) and the base (7) of the cutting edge (5) are horizontal. However, if the blade (2) is rectangular, such as a usuba knife, the tip (5 ) can be made so that all of them touch the horizontal plane.

[0019] In the above embodiment, the cross section of the handle (1) is oval, that is, the side surfaces are curved. , the side surface may have a flat surface, in short, if the cross-sectional shape is tapered downward, good. Also, if the top surface (10) of the handle (1) is flat, wrap it with the top surface (10) of the handle (1) facing down. When the knife is placed on a horizontal surface, it may end up standing with the cutting edge (5) facing upward, which is dangerous. Therefore, it is preferable that the upper surface (10) of the handle (1) has a convex arc shape in cross section. stomach.

[0020]

[Effect of the idea] When a knife based on this invention is placed horizontally on a horizontal surface, the handle extends over the entire length. At the same time, most of the cutting edge touches the horizontal surface. Therefore, hands etc. There is a risk of injury due to direct contact with the cutting edge, and there is a risk of injury or injury due to the knife rotating. This prevents the danger of the knife falling from the countertop, etc.
