Description

Technical Field

[0001] The utility model belongs to the field of kitchen knives, and in particular relates to an ergonomic knife with a finger pressure portion arranged on the back of the knife. Background Art

[0002] Knives are essential tools in daily family life, and families often need to have multiple knives, such as fruit knives, kitchen knives, etc. Knives usually include a knife body and a handle. The handle is installed on the rear end of the knife body. In order to facilitate holding and increase the hand feel, the handle is usually made of wood or other non-metallic materials.

[0003] A knife is generally composed of a blade and a handle. When in use, the handle is held in the hand to control the blade to achieve actions such as cutting, slicing, and chopping. Although the knife is controlled by the handle, the user's usage habits are different and the way of holding the knife is also different.

[0004] One of the gripping methods is to hold the knife handle with four fingers, while the thumb is pressing on the back of the knife. This gripping method is quite common. For people with weak wrist strength, pressing the back of the knife with the thumb can effectively increase force and help cutting. However, since the width of the existing knife back is smaller than the handle, the force-bearing area of ​​the knife back is smaller, making this gripping method with the thumb pressing on the knife back more strenuous, and long-term use can easily cause damage to the thumb. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model aims to provide an ergonomic knife with a finger pressure portion provided on the back of the knife.

[0006] The technical solution adopted by the utility model is:

[0007] An ergonomic knife with a finger pressure part on the back of the knife comprises a knife body and a knife handle. The finger pressure part is arranged at one end of the top of the knife body close to the knife handle. The finger pressure part is an arc-shaped surface and gradually widens in the length direction. The bottom of the knife handle is streamlined.

[0008] Preferably, the edges of the finger pressure parts have rounded corners.

[0009] Preferably, the finger pressure portion accounts for no more than 50% of the blade height.

[0010] Preferably, the blade body comprises a cutting portion and a gripping portion, the finger pressure portion is located between the cutting portion and the gripping portion, and the handle is mounted on the gripping portion.

[0011] Preferably, a plurality of clamping columns are provided on both sides of the gripping portion, and both sides of the gripping portion are connected to the knife handle via the clamping columns.

[0012] Preferably, an arc transition is adopted at the junction of the cutting portion and the gripping portion.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides an ergonomic knife with a finger pressure part on the back of the knife, comprising a blade and a handle, wherein the finger pressure part is provided at one end of the top of the blade close to the handle; the finger pressure part is an arc-shaped surface, and the finger pressure part gradually widens in the length direction; the bottom of the handle is streamlined. By providing the finger pressure part on the blade, when holding the knife, the other four fingers and the palm hold the handle, and the thumb presses on the finger pressure part from the top of the finger pressure part. This way of holding the knife can effectively increase the comfort of holding and applying force. The bottom of the handle is streamlined, which can effectively improve the anti-slip effect and reduce the friction between the fingers and the blade during use. The finger pressure part is arc-shaped, which can effectively prevent the handle from slipping from the hand when holding it. This design is more ergonomic and has a more reasonable structure.

[0024] In this embodiment, if Figures 1 to 7The ergonomic knife with a finger pressure part on the back of the knife shown in the figure comprises a blade 1 and a handle 2. A finger pressure part 3 is provided at one end of the top of the blade 1 close to the handle 2; the finger pressure part 3 is an arc-shaped surface, and the finger pressure part 3 gradually widens in the length direction; the bottom of the handle 2 is streamlined. By providing the finger pressure part 3 on the blade 1, when holding the knife, the other four fingers and the palm hold the handle 2, and the thumb presses on the finger pressure part 3 from the top of the finger pressure part 3. This way of holding the knife can effectively increase the comfort of holding and applying force. The bottom of the handle 2 is streamlined, which can effectively improve the anti-slip effect. When holding, even if the holding force is reduced, the problem of the handle slipping from the hand can be effectively prevented. The gripping force is reduced, and the friction between the fingers and the blade during use is immediately reduced. The finger pressure part is arc-shaped. This design is more ergonomic and has a more reasonable structure.

[0025] In this embodiment, the edges of the finger pressure part 3 are all rounded, and the rounded corners make the edges of the finger pressure part 3 more blunt and smooth, making the thumb and index finger more comfortable when holding the knife and preventing scratches and abrasions.

[0026] In this embodiment, the finger pressure portion 3 occupies no more than 50% of the blade body 1 in the height direction, so that the finger pressure portion 3 does not occupy a large area of ​​the blade body 1 .

[0027] In this embodiment, if Figure 2 and Figure 8 As shown, the blade 1 includes a cutting portion 11 and a gripping portion 12, the finger pressing portion 3 is located between the cutting portion 11 and the gripping portion 12, the handle 2 is mounted on the gripping portion 12, a plurality of clamping columns 4 are arranged on both sides of the gripping portion 12, and both sides of the gripping portion 12 are connected to the handle 2 through the clamping columns 4. The handle 2 is a split type arrangement, by dividing the handle 2 into two pieces and installing them from both sides of the gripping portion 12, the use process of the entire knife is made more convenient.

[0028] In this embodiment, if Figure 3 and Figure 8 As shown, the intersection of the cutting portion 11 and the holding portion 12 adopts an arc transition, which can effectively prevent stress concentration and effectively prevent defects such as cracks from occurring at the intersection of the cutting portion 11 and the holding portion 12 after frequent use.
