Commercial Vehicle Load Securing Grid Rail System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial vehicle body designs face challenges in securely fastening coils and slit strips, particularly during longitudinal acceleration, where slit tapes tend to tilt forward, leading to increased freedom of movement and high forces that traditional lashing systems struggle to absorb effectively.
Innovation Solution
A commercial vehicle body design featuring grid rails and support beams with locking lugs, combined with additional support struts and lashing chains, allows for secure placement of loads at an optimal center of gravity, preventing tilting and providing high load security with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lashing systems with support beams and tensioning ropes are used, then coils can be secured on the loading floor, but the system requires time-consuming and exhausting lashing and tensioning work
Solution Approach 1:
The patent extracts the complex tensioning operation by replacing it with a simple insertion action. The plug-in stanchions are pre-configured with pockets that directly receive lashing means, eliminating the need for support beams and tensioning ropes. This extraction of the problematic elements (beams and ropes) while retaining the essential function (load securing) directly reduces lashing time while maintaining reliability
Solution Approach 2:
The plug-in stanchions serve multiple functions: they provide structural support, enable load securing, and allow variable positioning along the loading floor. By consolidating these functions into a single component that can be positioned anywhere along the grid rails, the system achieves both high reliability and operational efficiency without requiring separate support beams and tensioning mechanisms
2Stability of the object's composition
If two support beams with tensioning ropes are used to secure coils, then the load can be restrained, but the lashing process becomes complex and time-consuming
Solution Approach 1:
The patent removes the complex support beam and tensioning rope system entirely, replacing it with simplified plug-in stanchions that have integrated pockets for lashing means. This extraction eliminates unnecessary components while preserving the essential function of restraining the load, thereby reducing device complexity without compromising stability
Solution Approach 2:
The patent merges the functions of support beams, tensioning ropes, and positioning mechanisms into a single integrated plug-in stanchion system. The stanchions combine structural support, load restraint, and variable positioning capabilities in one component, significantly reducing the number of parts needed while maintaining load position stability
3Device complexity
If fixed location support stanchions are used as in prior art, then the vehicle body structure is simplified, but the loading area flexibility is reduced
Solution Approach 1:
The patent transforms the static, fixed-location support stanchions of prior art into dynamic, movable plug-in stanchions that can be positioned anywhere along the grid rails. This dynamic positioning capability allows the loading area to be adapted to different coil sizes and weights, maximizing loading flexibility while keeping the vehicle body structure relatively simple through the use of standardized grid rails and receptacles

AI summary
The invention relates to a commercial vehicle body with a loading floor 4 supported on the ground via a chassis 2, the loading floor having a boundary 7 on each of its side edges provided with mounting receptacles 8, and a mounting rail offset inwards towards the central longitudinal axis of the loading floor at a distance from the side boundaries 7, wherein at least one coil recess 5 is provided in the loading floor between the mounting rails for receiving coils 6, slit strips 6.1 and the like, and wherein at least one support beam 12 extending transversely to the central longitudinal axis of the loading floor 4 can be fixed to the mounting rails 9 in a positionally variable manner for supporting the load 6, 6.1, in which at least one receptacle 12.1 for arranging an insertion stanchion 13 is provided, which supports the load 6, 6.1 against an end face, and with at least one flexible clamping means 17, 19, 20 for the load 6, 6.1.1, which can be fixed to the lateral boundaries 8 of the loading floor 4. In order to have implemented a load securing system on the commercial vehicle that can withstand higher loads, it is provided that the fastening rails are designed as grid rails 9 with grid receptacles 10 arranged at a distance from each other, in which a support beam 12 provided with fastening projections 12.1 can be locked in a positionally variable manner and that an insertion stanchion 13 of the support beam 12 is supported by a support strut 14, which is connected at one end to the insertion stanchion 13 and at the other end is offset forwards in one of the grid rails 9 at a positional distance from the support beam 12 when viewed in the direction of travel of the commercial vehicle (Fig. 1).
