TWD167658S - Open end wrench drive head - Google Patents

Abstract

【Item Usage】;This design is the driving head of an open-end wrench. ;[Design Description];This design is about the appearance design of the driving head of an open-end wrench, especially the driving head of an open-end wrench with a beautified appearance and unique visual aesthetics. ; Judging from the diagram, the driving head of the open-end wrench of this design is generally U-shaped, and the two opposite inner side walls are respectively designed with different convex shapes, so that the overall driving head provides an asymmetrical visual effect. ; To be more specific, a trapezoidal convex structure is designed on one inner side wall, and a shallow arc-shaped depression is designed on the upper surface of the trapezoidal convex structure to soften the too harsh visual effect of the trapezoidal convex structure. The other inner side wall is designed with four small hill-shaped arc-shaped protruding structures. Among them, the two arc-shaped protruding structures in the middle are the same size and shape, and the two left and right arc-shaped protruding structures are smaller in size and shape. The same, thus forming a symmetrical design arrangement, and the hill-shaped convex structures are juxtaposed on the same inner side wall, creating a streamlined and natural visual effect, which can also alleviate the seriousness of the trapezoidal convex structure on the other inner side wall, and form a whole The driving head of the open-end wrench adds an asymmetrical, conflicting, yet complementary visual experience. It can be seen from this that the driving head of the open-ended wrench of this design is indeed novel and original, so it meets the requirements for a design patent. I submit an application in accordance with the law and pray that the patent will be granted as soon as possible. ; The dotted line portion disclosed in the diagram is the portion of the case that is not intended to be designed.
