A dinner fork with elliptical fork teeth

Abstract

This utility model relates to the field of kitchen utensils, and more particularly to a fork with an elliptical fork tooth structure, comprising: a fork handle, a fork head, and a plurality of fork teeth, wherein the cross-section of the fork teeth is an elliptical structure; the elliptical structure has a major axis and a minor axis, the major axis corresponding to the lateral width of the fork teeth, and the minor axis corresponding to the vertical thickness of the fork teeth; the elliptical structure is inclined relative to the horizontal direction. Due to the elliptical structure, the thickness of the elliptical structure gradually increases from both ends to the center along the major axis, so the overall thickness of the fork teeth is thicker than that of the existing flat structure, which effectively improves the strength of the fork teeth and effectively reduces the vertical depth of polishing during processing, making processing easier. By tilting and offsetting the inner surfaces of two adjacent fork teeth, food residue is less likely to remain on the fork teeth during cleaning and use, making cleaning convenient. Moreover, this structure makes mold separation easier in production, making it easier to produce and form, effectively improving production efficiency and yield.

Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a fork with an elliptical fork tooth structure. Background Technology

[0002] The dinner fork is a common tool used in daily dining. It typically consists of a flat handle and several fine tines extending from the front, usually four, but sometimes two or three. It is primarily used to lift food to the mouth or to hold ingredients in place while cutting food, and is indispensable, especially when eating Western dishes such as steak, pasta, and salads. The use of a dinner fork greatly improves the convenience and neatness of eating, avoiding the inconvenience of directly grasping food with hands. It is mostly made of stainless steel, but there are also styles made of silver, titanium alloy, or environmentally friendly materials, balancing durability and aesthetics. The shape and size of dinner forks vary across different cultures and occasions. For example, children's forks are usually smaller and have blunter tines for safety, while at formal banquets, various special forks are arranged according to the order of the dishes. Today, the dinner fork is not only a practical utensil but also reflects the development of dining civilization and people's pursuit of a sense of ritual in dining.

[0003] Most existing dinner forks have their adjacent tines arranged in parallel or nearly parallel patterns. The space between the tines is small and relatively enclosed, making it easy for food residue to remain in the gaps after use. During the cleaning process, it is difficult for water to rinse them thoroughly, resulting in obvious cleaning dead spots. This not only affects hygiene but also increases the cleaning burden.

[0004] Secondly, most existing dinner forks have a flat structure. During use and cleaning, the sharp edges of the fork tines can easily cause food residue to get stuck in the corners, especially in the space formed by the corners between two adjacent tines, making cleaning quite troublesome. Utility Model Content

[0005] This application provides a dinner fork with elliptical tines, employing the following technical solution: A dinner fork with elliptical tines includes: a fork handle, a fork head, and a plurality of tines, wherein the cross-section of the tines is elliptical; the elliptical structure has a major axis and a minor axis, the major axis corresponding to the lateral width of the tines, and the minor axis corresponding to the vertical thickness of the tines; the elliptical structure is inclined relative to the horizontal direction.

[0006] Preferably, the projections of the inner major axis endpoints of two adjacent elliptical structures in the vertical direction have a height difference, and the height difference is less than half of the minor axis of the elliptical structure.

[0007] Preferably, the height difference is less than half the length of the shorter axis of the longer of the two elliptical structures.

[0008] Preferably, the fork tooth rotates about the major axis of the ellipse of the fork tooth cross section.

[0009] Preferably, the fork teeth rotate 5°-15°.

[0010] Preferably, the fork handle has a concave structure located near the top of the fork handle.

[0011] Preferably, a transition structure is provided at the junction of the fork head and the two adjacent fork teeth.

[0012] Preferably, the transition structure extends from the top of the short shaft on two adjacent fork teeth to the front end of the fork head, and is formed by intersecting and connecting with the fork head. The transition structure is an arc-shaped beveled groove that gradually becomes shallower towards the rear of the fork head. The transition structure is a transitional depression.

[0013] Preferably, the outer surfaces of the fork teeth and the fork head located on both sides are provided with transition arc surfaces.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This fork features an elliptical structure. Because the thickness of the elliptical structure gradually increases from both ends to the center along the long axis, the overall thickness of the fork teeth is thicker than that of existing flat structures, effectively improving the strength of the fork teeth. Furthermore, the curved ends of the elliptical structure allow for double-sided polishing instead of single-sided polishing, effectively reducing the vertical depth of polishing during processing, making processing easier, and resulting in a smoother overall finish. During cleaning and use, food residue is less likely to remain on the fork teeth, making cleaning convenient.

[0015] 2. This fork features an inclined design that creates an open space by tilting the inner surfaces of two adjacent tines, exposing the edges of the tines. This makes it easier to clean residue from the space between adjacent tines, reducing cleaning difficulty and improving rinsing efficiency. The concave structure on the fork handle also makes it fit the thumb joint more snugly during use, resulting in a more comfortable grip.

[0016] 3. The elliptical structure of this dinner fork facilitates the mold separation of the fork teeth during production. Using the major axis of the elliptical structure as the dividing line, the part above the major axis is divided into the upper mold unit, and the part below the major axis is divided into the lower mold unit. This makes mold separation more convenient, easier to produce and shape, and effectively improves production efficiency and yield. Attached Figure Description

[0028] An embodiment of this utility model provides a dinner fork with elliptical fork teeth.

[0029] Example 1: As Figure 1-6 The image shows a dinner fork with elliptical tines, comprising: a handle 1, a fork head 2, and a plurality of tines 3, wherein the cross-section of each tine 3 is elliptical; the elliptical structure has a major axis A and a minor axis B, where the major axis A corresponds to the lateral width of the tines 3, and the minor axis B corresponds to the vertical thickness of the tines 3; the elliptical structure is inclined relative to the horizontal direction. The projections of the inner major axis endpoints P1 and P2 of two adjacent elliptical structures in the vertical direction have a height difference H, which is less than half the length of the minor axis B of the elliptical structure. The height difference H is less than half the length of the longer of the two minor axes B of the elliptical structures, with the relationship: 0 < height difference H < 1 / 2 of the minor axis B. The tines 3 rotate about the major axis A of the elliptical cross-section of the tines 3 as a reference. The fork tines 3 are rotated by 5°, and the long axis A of the rotated fork tines 3 forms a 5° angle with the long axis A of the unrotated fork tines 3. This small rotation angle results in a smaller height difference H between points P1 and P2 on two adjacent fork tines 3, which improves the cleaning effect compared to existing parallel fork structures while maintaining the regularity of the overall appearance of the fork. The fork handle 1 has a concave structure 4 located near the top of the fork handle 1. A transition structure 5 is provided at the junction of the fork tip 2 and two adjacent fork tines 3. In the prior art, the connection between the fork tooth 3 and the fork head 2 is usually set as an arc-shaped transition structure to buffer stress concentration. In this application, the connection between the fork tooth 3 and the fork head 2 does not use an arc transition, but is provided with a V-shaped concave transition structure 5. The transition structure 5 extends from the top of the short shaft on two adjacent fork teeth 3 to the front end of the fork head 2 and is formed by intersecting with the fork head 2. The transition structure 5 is an arc-shaped beveled groove that gradually becomes shallower towards the rear of the fork head 2. The transition structure 5 is a transition concave, forming a V-shaped transition notch with the tip facing the inside of the fork head 2. This structure replaces the traditional arc-shaped transition structure, which greatly reduces the area of ​​the semi-open area of ​​the transition structure 5, effectively reduces the dead corners of the semi-open area, and makes the transition structure 5 easier to clean during the washing process of the fork. The outer surfaces of the fork tooth 3 and the fork head 2 on both sides are provided with transition arc surfaces 6.

[0030] Example 2: A dinner fork with elliptical tines, comprising: a handle 1, a fork head 2, and a plurality of tines 3, wherein the cross-section of each tine 3 is elliptical; the elliptical structure has a major axis A and a minor axis B, where the major axis A corresponds to the lateral width of the tines 3, and the minor axis B corresponds to the vertical thickness of the tines 3; the elliptical structure is inclined relative to the horizontal direction. The projections of the inner major axis endpoints P1 and P2 of two adjacent elliptical structures in the vertical direction have a height difference H, which is less than half the length of the minor axis of the elliptical structure. The height difference H is less than half the length of the longer of the two minor axes B of the elliptical structures, with the relationship: 0 < height difference H < 1 / 2 of the minor axis B. The tines 3 rotate about the major axis A of the elliptical cross-section of the tines 3 as a reference. The fork tooth 3 is rotated 15°, and the long axis A of the rotated fork tooth 3 forms a 15° angle with the long axis A of the unrotated fork tooth 3. This rotation angle is larger than that in Embodiment 1, resulting in a larger height difference H between points P1 and P2 on two adjacent fork teeth, and thus a better overall cleaning effect compared to the fork tooth 3 in Embodiment 1. The fork handle 1 is provided with a concave structure 4, which is located near the top of the fork handle 1. A transition structure 5 is provided at the junction of the fork head 2 and two adjacent fork teeth 3. In the prior art, the connection between the fork tooth 3 and the fork head 2 is usually set as an arc-shaped transition structure to buffer stress concentration. In this application, the connection between the fork tooth 3 and the fork head 2 does not use an arc transition, but is provided with a V-shaped concave transition structure 5. The transition structure 5 extends from the top of the short shaft on two adjacent fork teeth 3 to the front end of the fork head 2 and is formed by intersecting with the fork head 2. The transition structure 5 is an arc-shaped beveled groove that gradually becomes shallower towards the rear of the fork head 2. The transition structure 5 is a transition concave, forming a V-shaped transition notch with the tip facing the inside of the fork head 2. This structure replaces the traditional arc-shaped transition structure, which greatly reduces the area of ​​the semi-open area of ​​the transition structure 5, effectively reduces the dead corners of the semi-open area, and makes the transition structure 5 easier to clean during the washing process of the fork. The outer surfaces of the fork tooth 3 and the fork head 2 on both sides are provided with transition arc surfaces 6.

[0031] During the production process, the dinner fork mold is divided into an upper unit and a lower unit. The fork teeth 3 are split into two parts by an elliptical structure. The major axis A in the elliptical structure is used as the dividing line. The upper half of the ellipse with the major axis A is used as the upper unit of the mold, and the lower half of the ellipse with the major axis A is used as the lower unit of the mold. Compared with the existing dinner fork shape, the mold splitting is more convenient, and the dinner fork processed by the mold splitting is better and of higher quality.
