Part X: Rear support legs of the crane and rear bed guardrail

Abstract

[Purpose of the Article] The present design relates to the parts of the rear support leg and rear hopper guardrail of a crane truck, and is used for reinforced support and protective guardrail of a crane. [Description of the Design] The present design discloses a partial design of a rear support leg and a rear hopper guardrail of a crane truck. From the perspective view, the overall shape is mainly a large cuboid structure, the upper part is a vehicle bottom plate with a flat top surface, multiple groups of transversely arranged opening areas are arranged on both the left and right sides, and the visual effect of a grid with circular hole grids and solid dividing lines alternating is adopted. On the rear appearance, the solid dividing lines are in a double "earth" shape, and an opening area is also arranged between the dividing lines, which also adopts the design of circular hole grids, thus having an aesthetic effect. From the front view, the overall shape presents a horizontally extending rectangular appearance, the central part is the main vehicle girder which is also rectangular, located at the top and centered position of the maximum rectangular appearance, there is a rectangular connecting cross bar below the main vehicle girder, and square column sleeves are located on both sides of the rectangular connecting cross bar, all arranged in a left-right symmetrical manner. The bottom plate of the support leg inside the square column sleeve has a slightly tilted design; wherein the maximum rectangular appearance is formed by alternating hole areas and solid dividing lines located at the rearmost part, giving the whole a sense of layering. From the rear view, the overall shape presents a horizontally extending rectangular appearance, the main body is the rear hopper guardrail of the truck, which presents a double "earth" character shape, the space between the characters is filled with circular hole grids, and the interior can be faintly seen. Two square column-shaped support legs are located on the left and right sides of the main vehicle girder, presenting a symmetrical appearance. From the right side view, the main body presents a horizontal rectangular outline, with two upper and lower layers of circular hole grids arranged horizontally, separated by solid dividing lines. The internal rectangular connecting cross bar can be faintly seen, which is flush with the rearmost end of the main vehicle girder, and its side width is wider than that of the square column sleeve. The corners of the square column sleeve are designed with an arc shape, and the front and rear of the support leg base plate located inside the square column sleeve have an aesthetic design of slight tilting. From the left side view, it is a horizontally flipped form of the right side view. From the top view, it is the vehicle bottom plate covering the upper part. From the bottom view, the rear hopper guardrail has an n-shaped boundary, and the corners of the rectangular connecting cross bar also have a rounded corner design. From the reference view of the use state, the rear hopper guardrail as a whole covers components such as the main vehicle girder and the square column-shaped support legs, and the circular hole grids between the guardrails have an opaque effect due to the viewing angle. The "main beam", "floor", "solid dividing line" and "dual tires" covered in blue in the diagram are parts that this design does not advocate. In conclusion, although the entire design consists of rigid objects, it is composed of beautiful lines that possess the characteristics of strength and resilience, forming a unique and original appearance. It has indeed provided a distinct and different appearance design that has not been seen in the market or publications before the application. Therefore, a design patent application is hereby filed in accordance with the law.
