Part 4: Rear support legs and rear bed guardrail of the crane.

Abstract

[Purpose of Article] The present design relates to the portion of the rear supporting leg frame of a crane truck and the guardrail of the rear bucket of the truck, and is used for reinforced support and protective guardrail of a crane. [Description of Design] The present design discloses a partial design of the rear supporting leg frame of a crane truck and the guardrail of the rear bucket of the truck. Viewed from the perspective drawing, the overall appearance is a large cuboid structure as a whole, the upper part is a truck bottom plate with a flat top surface, multiple groups of opening areas arranged horizontally are arranged on both the left and right sides, and the visual effect of a grid formed by alternating circular hole grids and solid dividing lines is adopted. The solid dividing lines on the rear appearance are in a double "soil" 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. Viewed from the front view, the overall appearance presents a horizontally extending rectangular appearance, the center is a truck main beam which is also rectangular, located at the top and centered position of the largest rectangular appearance. Cylindrical supporting legs are arranged on the left and right sides inside the truck main beam, a double T-shaped partition plate is arranged between the cylindrical bodies on both sides and the truck main beam, and the side surface of the double T-shaped partition plate is also in a T-shaped style and connected with the inner side of the truck main beam, so that the whole presents the aesthetic effect of left-right symmetry; wherein the largest rectangular appearance is formed by alternating hole areas and solid dividing lines located at the rearmost part, which gives the whole a sense of layering. Viewed from the rear view, the overall appearance presents a horizontally extending rectangular appearance, the main body is the rear bucket guardrail of the truck, which presents a double "soil" shape, the space between the characters is filled with circular hole grids, and the interior can be vaguely seen. The supporting feet of two cylindrical bodies are located on the left and right sides inside the truck main beam, presenting a symmetrical appearance. Viewed from the right side view, the main body presents a horizontal rectangular outline, circular hole grids are horizontally arranged in two upper and lower layers and separated by solid dividing lines, the internal cylindrical supporting foot can be vaguely seen, and the cylindrical supporting foot transitions from a cylindrical section with a wider upper end downward to a narrower one to a disc-shaped base. Viewed from the left side view, it is a horizontally flipped version of the right side view. Viewed from the top view, the truck bottom plate covers the upper part. Viewed from the bottom view, the rear bucket guardrail of the truck is a ㄇ-shaped boundary, wherein the bottom of the cylindrical supporting foot is a circular base plate, the cylindrical supporting foot is covered by a double T-shaped partition plate, and the double T-shaped partition plate is connected with the truck main beam. Viewed from the reference drawing of the use state, the rear bucket guardrail of the truck overall covers components such as the truck main beam and the cylindrical supporting feet, 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.
