Description

Technical Field

[0001] This utility model relates to the field of household kitchenware, specifically to a household knife with a ring. Background Technology

[0002] In everyday kitchen utensils, such as a cleaver, there is usually a blade and a handle. The handle is attached to the end of the blade. The user holds the handle to control the cutting action. The user's feel when using a cleaver depends mainly on the handle and the way it is held. In common cleaver grips, four fingers are wrapped around the handle, and the thumb applies pressure to the handle, or the thumb and four fingers are wrapped around the handle together. In this way, the maximum distance between the user's hand and the handle is the width of the handle. The handle is usually attached to the side of the blade near the back of the blade. The user's main control force comes from the handle. The part of the handle that extends to the side (the back of the blade) is easier for the user to control. Conversely, the blade is furthest from the handle where the user applies force, resulting in an imbalance in control of the blade when cutting. This can easily cause the blade to tip over. Also, when applying force, the side of the blade or the opening in the blade can easily scratch the index finger. Placing the handle directly in the middle of one side of the blade makes it difficult to apply force. Therefore, this grip method, which mainly transmits grip force through the handle, reduces the feel of using a cleaver. Utility Model Content

[0003] This utility model of a household knife with a finger ring can effectively solve the problem of the knife body easily tipping over when pressed down in the above-mentioned everyday knives.

[0004] According to one aspect of the present invention, a household knife with a ring is provided, comprising:

[0005] The blade body has a cutting edge for cutting and a back blade disposed opposite to the cutting edge;

[0006] A handle for gripping, the handle being disposed on one side of the blade;

[0007] A finger ring is provided on the blade body and on the side near the handle, the finger ring having a finger hole for a finger to pass through;

[0008] Wherein, the minimum distance between the finger hole and the back of the blade is greater than or equal to the maximum distance between the handle and the back of the blade.

[0009] In some embodiments, the outer circumference of the ring is provided with a first finger groove that is radially recessed, the opening of the first finger groove facing the handle. Thus, during use, the index finger grips the finger hole tightly, while the other fingers near the conductor can rest against the first finger groove, improving grip comfort.

[0010] In some embodiments, the finger hole and the projection of the cutting edge onto the back of the blade do not coincide. This provides an alternative blade shape where the cutting edge does not extend below the finger hole.

[0011] In some embodiments, the outer circumference of the ring is provided with a first finger groove that is radially recessed, the opening of the first finger groove facing the blade. This allows the user's index finger to grip tightly onto the finger hole or the first finger groove, increasing the width of the index finger gripping the blade.

[0012] In some embodiments, the axial end face of the finger ring is provided with a second finger groove that is recessed along the axial direction. This allows the side of the finger to fit against the second finger groove during use, bringing the hand closer to the blade, improving grip comfort and balancing the control of the blade.

[0013] In some embodiments, the finger hole has a rounded edge. This rounded edge increases the comfort of the finger joint when the index finger is clenched.

[0014] In some embodiments, the finger hole penetrates the blade body and is located between the back of the blade and the cutting edge. Thus, the finger hole is positioned between the back of the blade and the cutting edge, with the cutting edge portion located below the finger hole.

[0015] In some embodiments, the blade body has a mounting hole, and the ring is detachably mounted in the mounting hole. Thus, the ring is detachably mounted to the blade body via the mounting hole.

[0016] In some embodiments, the ring includes:

[0017] A sleeve is detachably installed in the mounting hole, and the finger hole is provided on the sleeve;

[0018] The first ring is connected to one end of the sleeve along its axial direction;

[0019] The second ring is connected to the other end of the sleeve along its axial direction.

[0020] This provides a specific structure for the ring, allowing it to be detachably mounted on the blade.

[0021] In some embodiments, both the first and second collars have contact surfaces that extend along the direction close to the sleeve. This allows the index finger to contact the contact surface, facilitating finger pressure and improving both the strength and comfort of the clamping action.

[0022] This utility model provides a household knife with a ring, which has the following advantages compared with the prior art:

[0023] The household knife with finger ring of this application effectively protects fingers and prevents cuts and slippage by setting finger rings on the blade. Users can tightly grip the finger hole to control the blade. The minimum distance between the finger hole and the back of the blade is greater than or equal to the maximum distance between the handle and the back of the blade. The distance between the index finger and the blade is closest when the finger is tightly gripped, and the width of the index finger grip is equal to or greater than the width of the handle, which improves the control of the blade and makes the grip more comfortable. By increasing the width of the index finger gripping the finger hole, the balance of the blade is controlled, and the downward cutting direction of the blade is easier to control, making it less likely for the blade to deflect or tip over.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] This utility model relates to a household knife with a finger ring, which is particularly suitable for everyday kitchen knives. As a new type of knife that can replace traditional kitchen knives, it has the advantages of improved hand feel and easier grip. Of course, the structure of this knife is not limited to kitchen knives, but is also applicable to other hand-held knives.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] Figure 1 A household knife with a ring handle (hereinafter referred to as "knife") according to one embodiment of the present invention is schematically shown. Figure 1 As shown, for ease of description, the length direction of the knife is taken as the left-right direction and the width direction of the knife is taken as the up-down direction. The household knife with a finger ring 3 includes a knife body 1 and a handle 2.

[0039] like Figure 2 As shown, this knife is similar in appearance to a common kitchen knife, with the blade body 1 having a back 13 and a cutting edge 12. The specific shape of the blade body 1 is not limited and can be set according to actual use. The back 13 and the cutting edge 12 are arranged opposite each other in the width direction. The back 13 is on the upper side of the blade body 1 and has a thickness corresponding to the blade body 1, while the cutting edge 12 is on the lower side of the blade body 1 and can be used for cutting food. The handle 2 is a component for the user to hold and is located on one side (right side) of the blade body 1 in the length direction. The combination of the blade body 1 and the handle 2 can refer to existing designs. In this embodiment, the handle 2 adopts a flat cylindrical structure and is located on the upper side of the blade body 1. The handle 2 is flush with the back 13 in the width direction.

[0040] Among them, such as Figure 4As shown, a finger ring 3 is provided on the blade body 1. The finger ring 3 has a regular ring structure and is located on the side near the handle 2, that is, on the right side of the blade body 1. The finger ring 3 has a through finger hole 332, through which the user's fingers can pass to grip the blade. Specifically, the blade body 1 has a mounting hole 11, which is a through hole on the blade body 1 to provide a position for the finger ring 3. The finger ring 3 can be detachably installed in the mounting hole 11. It can be embedded in the blade body 1 by snap-fit ​​or other installation methods. Since the finger ring 3 is located close to the handle, the user can hold the blade by passing his / her fingers through the finger hole 332 to grip and control the blade. For example, the index finger can pass through the finger hole 332 and bend to grip tightly, while the other four fingers grip the handle tightly. The user's index finger exerts force on the blade body 1, and the force exerted by the other four fingers is transmitted to the blade body 1 by the handle 2. In this embodiment, the lengths of the back of the blade 13 and the blade 12 correspond, and the finger hole 332 penetrates the blade body 1 and is located between the back of the blade 13 and the blade 12. That is, the blade 12 portion is located on the lower side of the finger ring 3, which can be used for cutting.

[0041] To improve the user experience, this knife changes the traditional way of holding it and the way force is controlled on the blade body 1, such as... Figure 3 As shown, the minimum distance between the finger hole 332 and the blade back 13 is set to be greater than or equal to the maximum distance between the handle 2 and the blade back 13. This brings the user's index finger closer to the blade 12, and since the index finger applies force to the blade body 1, the user's grip angle is increased, thereby increasing the control feel of the blade body 1. Therefore, the control direction of the blade 12 is more balanced, and it is less likely to deflect from the two sides of the blade body 1. Specifically, the handle applies force to the blade body 1 to control the downward cutting direction of the blade 12. In the width direction, the width of the handle 2 extending to the left to the blade body 1 can be denoted as the equivalent distance D. The handle applies force to the structure within the equivalent distance D for the downward cutting control effect (similar to the control direction of a long stick). In this embodiment, the blade back 13 is flush with the handle 2, that is, in the width direction, the maximum distance between the lower side of the handle 2 and the blade back 13 is the equivalent distance D1 (the width of the handle). The equivalent distance D1 is the optimal distance for the handle to apply force. The user's index finger passes through the finger hole 332 to apply force to the blade body 1. That is, in the width direction, the minimum distance between the finger hole 332 and the blade back 13 is the equivalent distance D2. Since the index finger itself has width, the equivalent distance D2 will be larger in actual use. In this embodiment, the equivalent distance D2 is greater than or equal to the equivalent distance D1. Since the user's four fingers are tightly gripping the handle and applying force, the index finger can also apply force directly to the blade body 1 by passing through the finger hole 332. Moreover, the index finger is closer to the blade 12 than the other four fingers, making it easier to control the downward cutting direction of the blade 12 and less prone to deflection.

[0042] In addition, the ring 3 is directly installed in the mounting hole 11 of the blade body 1. The ring 3 seals the inner wall of the mounting hole 11, so that the index finger does not come into contact with the inner wall of the mounting hole 11 when it is tightly gripped. This provides more comprehensive protection when force is applied to the index finger and will not scratch it.

[0043] Furthermore, such as Figure 5 As shown, the finger ring 3 includes a sleeve 33, a first collar 31, and a second collar 32. The sleeve 33 is detachably installed in the mounting hole 11. The finger hole 332 is disposed on the sleeve 33. The sleeve 33 has a cylindrical structure, and both the first collar 31 and the second collar 32 have annular structures. The interiors of the first collar 31 and the second collar 32 can be connected to the outer circumference of the sleeve 33 by a snap-fit ​​method. The first collar 31 is connected to one axial end of the sleeve 33, and the second collar 32 is connected to the other axial end of the sleeve 33, so that the end faces of the first collar 31 and the second collar 32 fit against the blade surface of the blade body 1. The finger hole 332 has a rounded edge 331, meaning that the inner wall of the sleeve 33 is formed by the rounded edge 331. When the user's index finger grips the finger hole 332, the rounded edge 331 can improve the comfort of the finger joint. The finger ring 3 can be made of plastic.

[0044] like Figure 6 As shown, the outer circumference of the ring 3 is provided with a first finger groove 35 that is recessed radially. Specifically, the first finger groove 35 is provided on the first ring 31 and the second ring 32. The first finger groove 35 is a groove structure with an arc structure, which is adapted to the side of the user's finger. The opening of the first finger groove 35 faces the handle 2. When the ring 3 is installed on the blade 1, the right side of the ring 3 protrudes from the right end face of the blade 1, so that the first finger groove 35 is closer to the handle than the right end face of the blade 1. When in use, the user's index finger is pressed into the finger hole 332, and the other four fingers are gripped tightly on the handle. The finger (middle finger) close to the right end face of the blade 1 can fit in contact with the first finger groove 35. Therefore, the first finger groove 35 isolates the user's finger from the right end face of the blade 1, avoiding the problem of the end face of the blade 1 scraping the finger when the user uses it for a long time, and further improving the user's grip.

[0045] like Figure 7 As shown, the finger ring 3 is also provided with a second finger groove 36. The second finger groove 36 is a groove structure and is set on the axial end face of the finger ring 3, that is, the second finger groove 36 is provided on the end face of the first ring 31 and the second ring 32. The second finger groove 36 is recessed along the axial direction. The second finger groove 36 is preferably a groove with an arc structure, which can fit with the user's finger when in use. Two second finger grooves 36 can be arranged opposite each other in the radial direction of the finger ring 3. In this embodiment, the second finger groove 36 is arranged along the length direction of the blade. The finger can fit with the second finger groove 36, so that the hand is closer to the blade body 1, improving the grip and comfort of use.

[0046] In some embodiments, such as Figure 5 As shown, both the first ring 31 and the second ring 32 are provided with a contact surface 34. The contact surface 34 can be a sloping surface or an inclined curved surface structure. The contact surface 34 is an inclined surface at the axial end of the first ring 31 and the second ring 32. The two contact surfaces 34 extend along the direction close to the sleeve 33, so that the arc edge 331 of the sleeve 33 is connected between the contact surfaces 34. The axial width of the sleeve 33 is smaller than the axial width of the finger ring. When in use, the index finger is tightly gripped in the finger hole 332. The two contact surfaces 34 can respectively meet the first and second joints of the index finger, improving comfort and facilitating the control of the blade body 1.

[0047] In some embodiments, such as Figure 8 As shown, another blade shape for the blade body 1 is provided, where the lengths of the blade back 13 and the blade 12 do not correspond. In this embodiment, the length of the blade 12 does not extend below the finger ring 3. Preferably, the blade 12 portion is not provided below the finger hole 332, meaning the finger hole 332 and the blade 12 do not coincide in the width direction, and the projections of the finger hole 332 and the blade 12 onto the blade back 13 do not overlap. At this time, the lower right side of the blade body 1 has an open structure, and the finger ring 3 can be completely snapped onto the edge of the opening, or it can be engaged through the mounting hole 11. In this embodiment, the opening of the first finger groove 35 faces the blade 12, that is, towards the lower side of the blade body 1. In the width direction, the equivalent distance D3 between the first finger groove 35 and the blade back 13 is the largest. When the user uses it, the index finger can still be tightly gripped on the finger hole 332, or tightly gripped on the first finger groove 35, closer to the blade 12 portion. Therefore, the above structure provides two gripping methods to adapt to different users and improve grip comfort.

[0048] In some embodiments, such as Figure 9 As shown, multiple regularly shaped and evenly arranged grooves are provided on the axial end face of the finger ring 3, forming anti-slip grooves around the finger ring 3 for gripping. For example, they are set on the contact surface 34. When in use, they fit against the joint of the index finger, increasing the gripping effect and improving the comfort of the index finger when gripping the blade 1. The evenly arranged grooves cooperate with the fingers, increasing the contact area of ​​the fingers when transitioning from the thicker handle 2 to the thinner blade 1, thus improving the comfort of gripping.

[0049] It is understood that the equivalent distance D on the blade body 1 when holding the knife of this application is larger, which makes it easier to control the blade body 1, making it less likely to deflect when pressing down to cut, increasing comfort and controllability. In addition, the finger ring 3 can protect the fingers, prevent cuts and slippage, and provide a gripping method with greater gripping force, making it easier to apply force. The finger ring 3 conforms to the curvature of the fingers, making it easier for the index finger to be placed and gripped more comfortably, which is conducive to improving the user experience.

[0050] The above description is merely a preferred embodiment of the present utility model. To simplify the description, not all possible combinations of the various technical features in the above embodiments have been described, and this is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
