DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(8) FIG. 2 is a schematic diagram of a spatula according to an embodiment of the present invention. As shown in FIG. 2, the spatula 100 comprises a blade portion 110 and a shaft portion 120. The blade portion 110 has a blade surface 111 and a sidewall 112 protruding out from the blade surface 111. The shaft portion is connected to the sidewall 112 of the blade portion 110 along a first extension axis A1. The orthographic projection of the first extension axis A1 on the blade surface 111 does not pass through the center of the blade surface 111. That is, the shaft portion 120 is not connected a central portion of a side edge 1112, which is close to the shaft portion 120, of the blade surface 111. For example, the shaft portion 120 of the present invention is connected to the junction of two adjacent side edge 1112 and 1113 of the blade surface 111 (i.e. a first corner 1111 of the blade surface 111), and an angle 1 between the shaft portion 120 and the side edge 1112, for instance, can be an acute angle. However in other embodiments of the present invention, the angle 1 can be a right angle or obtuse angle. A side edge 1114 of the blade surface 111 opposite to the side edge 1113 can be a front edge of the blade surface 111, as the front edge is usually the first part of the spatula 100 to contact with the food when using. Moreover, the blade surface 111 is a flat surface in this embodiment, but the present invention is not limited thereto. In another embodiment, the blade surface 111 is curve; and more particularly, the blade surface 111 can be concaved or in a shape of a spoon.

(9) As the front edge is the side edge 1114 of the blade surface 111, the aforementioned sidewall 112 is, for example, at least disposed on the first extension axis A1. Specifically, sidewall 112 at least is disposed along the side edge 1113. In the present embodiment, the sidewall 112 protrudes from the two side edges 1112 and 1113, which are adjacent to the first corner 1111, of the blade surface 111. That is, the sidewall 112 is extended from the side edge 1113 to the side edge 1112. Therefore, a side edge 1115 of the blade surface 111 opposite to the side edge 1112 also can be the front edge of the blade surface 111. In another embodiment of the present invention, the sidewall 112 is extended from the side edge 1113 to the side edges 1115 and 1112. In addition, the blade portion 110 of this embodiment further comprises a connecting portion 113 extending from the sidewall 112, and the shaft portion 120 is connected to the connecting portion 113. More specifically, the connecting portion 113 includes, for example, a plug-in cavity 1131; and the shaft portion 120 is plugged into the plug-in cavity 1131 to connect the first corner 1111 through the connecting portion 113. In an embodiment, the connecting portion 113 and the shaft portion 120 is a one-piece structure.

(10) The blade surface 111 of this embodiment further includes a second corner 1116 opposite to the first corner 1111, which is also the junction of the side edges 1114 and 1115. The sidewall 112 is not protruded from two side edges 1114 and 1115 of the blade surface 111 adjacent to the second corner 1116. The second corner 1116 is, for example, a curved corner. In an embodiment, the second corner 1116 has an arc radius in a range of 5 mm-300 mm; however, a specific shape of the second corner 1116 is not limited therein. For instance, the second corner 1116 can also be a clipped corner or a 90 degree corner. Moreover, an angle 2 between the two side edges 1114 and 1115, which are adjacent to the second corner 1116, for example can be more than or equal to 90 degrees. In another embodiment, the angle 2 can be less than 90 degrees. In addition, the two side edges 1114 and 1115, which are adjacent to the second corner 1116, singularly can be straight or curved/arc. An arc radius in the case of a curve side edge, for example, can be more than 50 mm, but the invention is not limited therein. As shown in FIG. 2, the two side edges 1114 and 1115 adjacent to the second corner 1116 are both arc side edges.

(11) The abovementioned shape(s) of the blade surface 111 is for illustration only, the present invention is not limited therein. Additionally, the shaft portion 120 of the present embodiment, for instance, includes a shaft body 121. The shaft body 121, for instance, includes a first portion 1211, and a second portion 1212 connecting with the first portion 1211. Wherein the first portion 1211 is extended along the first extension axis A1 to connect to the sidewall 112 of the blade portion 110; and the second portion 1212 is extended along a second extension axis A2. An orthographic projection of the second extension axis A2 on the blade surface 111 is between the center O of the blade surface 111 and the orthographic projection of the first extension axis A1 on the blade surface 111. In other words, the orthographic projection of the second extension axis A2 on the blade surface 111 can pass through the center O of the blade surface 111 or be in-between the center O and the sidewall 112. The first portion 1211, for example, is connected to the junction of the two adjacent side edges 1112 and 1113 of the blade surface 111 (i.e. the first corner 1111 of the blade surface 111), hence there is a bend formed between the first portion 1211 and the second portion 1212. And thus an operating direction of the whole spatula 100 can be adjusted for easier holding and easier operation. An angle 3 between the abovementioned orthographic projection of the second extension axis A2 on the blade surface 111 and the orthographic projection of the first extension axis A1 on the blade surface 111, for example, is an acute angle in a range of 5-45 degrees. A degree of the acute angle 3 can be adjusted depending on different sizes of the blade portion. The present embodiment is preferably in a range of 15-18 degrees in order to put the barycenter of the spatula 100 in an optimum position. It is noted that depending on different shapes of the blade portion, the orthographic projection of the second extension axis A2 on the blade surface 111 can also be in-between the center O and the sidewall 112. In other embodiments, the shaft body 121 can be straight without bending, or the entire shaft body is curved.

(12) The shaft portion 120 of the present embodiment further includes a holder 122. The holder 122 is applied to the second portion 1212 to provide functions of heat isolation and easier holding. The holder 122 is circularly surrounds the second portion 1212, wherein the holder 122 and the second portion 1212 can be a one-piece structure or two separately formed pieces. Moreover, the blade portion 110 and the shaft portion 120 can be assembled or a one-piece structure depending on different designs. Scilicet, the blade portion 110 and the shaft portion 120 can be two separately formed pieces being assembled thereafter. Or the blade portion 110 and the shaft portion 120 are an inseparable one-piece structure, the shaft portion 120 is extended out from the sidewall 112, and the blade portion 120 does not include the above connecting portion 113.

(13) FIG. 3 is a schematic side view of a spatula according to another embodiment of the present invention. As shown in FIG. 3, in this embodiment, the first portion 1211 of the shaft body 121, for instance, is inclined with respect to the blade surface 111 to form a first obtuse angle 4 with the blade surface 111; and the second portion 1212 of the shaft body 121, for instance, is inclined with respect to the blade surface 111 to form a second obtuse angle 5 with the blade surface 111. Wherein the first obtuse angle 4 is smaller than the second angle 5. In other words, the second portion 1212, for instance, is bended toward an extension surface P of the blade surface 111 with respect to the first portion 1211. A distance D between the bending portion (the junction/connecting portion of the first portion 1211 and the second 1212) and the extension surface P can be adjusted/designed depending on a depth of the frying pot. In FIG. 3, the first portion 1211 may be extended along the first extension axis A1 (as shown in FIG. 2) to connect to the sidewall 112 of the blade portion 110, and the second portion 1212 may be extended along the second extension axis A2 (as shown in FIG. 2). In another embodiment, the first portion 1211 and the second portion 1212 may both be extended in the first extension axis A1 (as shown in FIG. 2).

(14) The shaft portion 120 is separated into the first portion 1211 and the second portion 1212 in the present embodiment; however in other embodiments, the entire shaft portion can be straight or curved without a bending portion, and has no separation of the first portion and the second portion. Moreover, the blade portion 110 can further include a bottom surface 114 opposite to the blade surface 111. In the present embodiment, the bottom surface 114, for example, is a flat surface, but a specific shape of the bottom surface 114 of the present invention is not limited herein. For instance, the bottom surface 114 can be a curved surface. In addition, in other embodiments, the blade portion 110 can further include one or more through holes (not shown in figures), penetrate from the blade surface 111 to the bottom surface 114 for a function of being a slotted spatula turner, wherein a shape of the through holes can be rounded circular or linear, it is not limited herein.

(15) FIG. 4 is a schematic diagram for operating the spatula as shown in FIG. 2. As shown in FIG. 2 and FIG. 4, the shaft portion 120 is extended along the first extension axis A1 to connect with the sidewall 112 of the blade portion 110, the orthographic projection of the first extension axis A1 does not pass through the center O of the blade surface 111 that the shaft portion 120 is connected to the first corner 1111 of the blade surface 111, and thus a height for a user raising an arm 70 can be reduced when using the spatula 100 of the present embodiment. The user only needs to use his/her elbow 71 as a center for swinging back and forth of the forearm 72 to fry the food. This operation is more ergonomic and can improve the problems encountered when using a Chinese frying pan (wok) with a western system kitchenware that is easier to result in shoulder discomfort and sore muscles as using a conventional spatula. Additionally, as shown in FIG. 3, because the second portion 1212 of the shaft portion 120 is bended toward an extension surface P of the blade surface 111 with respect to the first portion 1211, a height of the raised arm can be further reduced when using the spatula 100.

(16) It is noted that the spatula 100 as shown in FIG. 2 is for right hand users. In other embodiments, a spatula can be designed for a left hand user by following the above illustrated principles/rules. As shown in FIG. 5, a spatula 100a has a mirror structure of the spatula 100 as shown in FIG. 2, and the spatula 100a is in accordance with the structure of the spatula 100 as shown in FIG. 2. The structure of the spatula 100a is suitable for left had users and also has the abovementioned functions and advantages.
