Technical Field

[0001] This utility model relates to the field of kitchen knife technology, specifically to a novel knife handle with an auxiliary grip surface. Background Technology

[0002] Kitchen knives are an indispensable part of people's daily lives. With the improvement of production technology and processes, there are now a wide variety of kitchen knives available. Compared with the production of old-style knives and handles, modern kitchen knives are becoming more and more integrated, using one-piece molding or bonding technology to achieve a high degree of fixation between the handle and the knife body.

[0003] Existing tool holders are generally manufactured by fitting multiple curved surfaces together and then forming them into a single piece using a corresponding mold. However, with only a single curved surface, the user may experience instability in the grip, or even some deflection, which can have a negative impact on the user's experience.

[0004] In addition, some knife handles are made with a one-piece blade and a non-alloy handle glued to the outside of the blade to improve economic efficiency. However, after long-term use, the gap between the handle and the blade is prone to accumulating dirt and grime, and bacteria can also grow in the relatively humid and mild conditions of the kitchen. Because it is a glued structure, it is not easy to clean. Utility Model Content

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1, refer to the appendix of the instruction manual Figure 1-4 A novel knife handle with an auxiliary grip surface includes a main body 1 for supporting the blade and guards 2 disposed on both sides of the main body 1 and detachably connected to the main body 1. The side of the guard 2 closest to the blade of the main body 1 can be arc-shaped or right-angled, but is generally arc-shaped, as the arc shape can better fit the main body 1.

[0027] The blade is generally integrally formed with the main body 1. The blade can be made into various shapes such as a chef's knife, a cleaver, or a regular dinner knife, depending on the needs. The handle 2 is detachably connected to the main body 1 and can be replaced according to the weight requirements of different users. At the same time, after a certain period of use, the staff can also remove the handle 2 to thoroughly clean the main body 1 and the handle 2.

[0028] The main body 1 has a hand guard 3 near the blade. The hand guard 3 and the handle 2 of the main body 1 have auxiliary grip surfaces. The auxiliary grip surfaces are located in the space formed by the palm and fingers. The hand guard 3 is located between the handle 2 and the blade to prevent the blade from injuring the user when using the knife. The auxiliary grip surfaces are a combination of curved and flat surfaces to make the knife grip part more stable in the user's hand.

[0029] The auxiliary grip surfaces include a fingertip contact surface 4, a palm contact surface 5, and a fingertip contact surface 6. The fingertip contact surface 4, the palm contact surface 5, and the fingertip contact surface 6 are connected by a curved connecting surface 7. The fingertip contact surface 4 and the palm contact surface 5 are located on the upper and lower sides of the main body 1 and the handle 2 and form a continuous space. The fingertip contact surface 6 is located on the hand guard position 3 of the main body 1 and the left and right sides of the handle 2 and is perpendicular to the continuous space formed by the fingertip contact surface 4 and the palm contact surface 5.

[0030] The fingertip contact surface 4 is curved, which can fit the fingertip of the user when holding the hand. The palm contact surface 5 is located directly above the fingertip contact surface 4. At the same time, the palm contact surface 5 is a combination of flat and curved surfaces. The flat part fits the palm, increasing the grip stability. There are two fingertip contact surfaces 6. One side of the fingertip contact surface 6 is located at the fingertip when holding the hand with the left hand, and the other side of the fingertip contact surface 6 is located at the fingertip when holding the hand with the right hand, providing corresponding pressure points for the fingertips, which can further improve the grip stability.

[0031] The main body 1 has multiple fixing holes 8, and the fingertip contact surface 6 has a limiting hole 9 corresponding to the fixing hole 8. The fixing hole 8 and the corresponding limiting hole 9 are connected by a limiting structure. The limiting structure can be a columnar body with a diameter slightly larger than the limiting hole 9 and the fixing hole 8. The columnar body is inserted into the limiting hole 9 and the fixing hole 8 by means of a tool.

[0032] The limiting structure may also include a stepped groove 10, a limiting male end 11, and a limiting female end 12. The stepped groove 10 is opened in the limiting hole 9 and is located on the side of the limiting hole 9 near the fingertip contact surface 6. The limiting male end 11 is located in one of the stepped grooves 10, and the limiting female end 12 is located in the other stepped groove 10 and is threadedly connected to the limiting male end 11. The limiting female end 12 and the limiting male end 11 are provided with stepped surfaces corresponding to the stepped grooves 10. The stepped groove 10 limits the distance between the handle 2 and the main body 1 by fitting with the stepped surface.

[0033] The handle 2 has a groove 13 on the side near the main body 1, and the main body 1 has a slide 14 that is inserted into the groove 13. The connection between the slide 14 and the groove 13 is used to limit the handle 2 when it is disassembled, and to perform initial positioning when the handle 2 is installed.

[0034] A positioning auxiliary groove 15 is provided on the inner edge surface of the slide groove 13, and a positioning block 16 is provided on the slide 14 to be inserted into the positioning auxiliary groove 15. The outwardly protruding positioning block 16 and the inwardly recessed positioning auxiliary groove 15 are used to assist in the positioning between the handle 2 and the main body 1.

[0035] The main body 1 has a limiting groove 17 for limiting the handle 2. The side of the handle 2 near the hand guard position 3 has a limiting rod 18 that is inserted into the limiting groove 17. The limiting rod 18 is inserted into the limiting groove 17. The limiting groove 17 has multiple hemispherical slots 19. The limiting rod 18 is connected by a spring to a ball 20 that is inserted into the hemispherical slot 19. The insertion of the ball 20 into the hemispherical slot 19 is used to reduce the force when the handle 2 closes to the main body 1, thus playing a buffering role.

[0036] Example 2: The interior of the main body 1 can also be hollow. A hollow main body 1 can reduce the weight of the main body 1 and make it easier to process. The space formed by the handle 2 and the main body 1 is provided with multiple support ribs 21. The support ribs 21 are used to enhance the internal structure of the main body 1. Under the action of the support ribs 21, the main body 1 can increase a certain load-bearing capacity.

[0037] In use, the user can release the restriction between the handle 2 and the main body 1 by disassembling the limiting sub-end 11 and the limiting female end 12. Due to the insertion of the sliding groove 13 and the sliding track 14, the handle 2 and the main body 1 will not be directly separated after the restriction structure is released. By pulling the handle with a certain force, a sliding separation between the handle and the main body 1 can be achieved. During the separation process, the edge of the hemispherical groove 19 presses against the outer edge of the ball 20, causing the ball 20 to press against the spring and squeeze into the limiting rod 18. After passing through multiple hemispherical grooves 19 and the ball 20, the limiting rod 18 moves out of the limiting groove 17. At this time, the user can quickly separate and pull out the handle 2 from the main body 1.

[0038] After the handle 2 is separated from the main body 1, the main body 1 and the handle 2 can be cleaned from all angles. The material of the handle 2 can also be replaced according to the corresponding needs. Replacing the material of the handle 2 can not only improve the aesthetics of the product, but also change the center of gravity of the handle, making it suitable for more users. After cleaning and replacement, the user can reverse the above steps to get a knife with a brand new handle.

[0039] This utility model uses an auxiliary gripping surface on the handle 2 to increase the gripping stability of the user. The combination of curved and flat surfaces in the auxiliary gripping surface can be gripped more stably by the user.

[0040] This utility model also adopts a detachable handle 2 and a main body 1. By disassembling the handle 2 and the main body 1, the material of the handle 2 can be replaced. By changing the material and selecting the material, the comfort of the user can be increased. The center of gravity can also be changed according to the replacement of the handle 2, which is more in line with the usage habits of different people. On the other hand, after a period of use, the disassembly of the handle 2 and the main body 1 can be used to clean and disinfect the main body 1 and the handle 2 in an all-round way, avoiding the growth of bacteria under long-term use.
