Trailer Step Bracket Structure for High Flatbed Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailers pose challenges for individuals attempting to step up onto or down from them due to the height of the trailer platform, which requires considerable physical effort and increases the risk of strain or injury, especially for those with limited strength or mobility.
Innovation Solution
A trailer step bracket device that includes a pair of symmetrical mounting plates with long and short arms, steps-supporting horizontal arms, and a pivot member, which securely attaches to a flatbed trailer and supports fold-out camper or trailer steps, providing a stable and secure platform for users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional fold-out steps are used alone, then the structure remains simple, but the steps cannot provide adequate height to bridge the gap between ground and trailer platform
Solution Approach 1:
The bracket device serves as an intermediary structure between the ground and the trailer platform. It includes a first mounting plate with long and short arms that attaches to the trailer, a second mounting plate with similar arms that supports the fold-out steps, and horizontal arms that connect these plates. This intermediary bracket system extends the effective height of the steps, bridging the gap between the ground and the elevated trailer platform while maintaining structural integrity.
2Ease of operation
If the trailer platform height is reduced, then ease of access improves, but the trailer platform can no longer accommodate standard cargo containers and equipment
Solution Approach 1:
The solution segments the access function from the platform structure. The bracket device is divided into multiple components: first mounting plate, second mounting plate, long arms, short arms, and horizontal arms. This segmentation allows the platform to maintain its standard height for cargo compatibility while the segmented bracket system provides the additional height needed for easy access, with each segment contributing to the overall extended step height.
3Loss of time
If users jump or hop off the trailer to get down, then the process is quick, but the impact can lead to muscle strains, twisted ankles, or severe injuries
Solution Approach 1:
The bracket device with its extended horizontal arms acts as an intermediary landing structure between the trailer platform and the ground. Users can step down onto the extended arms or the supported fold-out steps rather than jumping directly to the ground. This intermediary structure reduces the impact force, preventing injuries while maintaining a quick exit process, as users can simply step down onto the extended platform rather than hopping.
4Ease of operation
If conventional steps are used without extension, then the device complexity remains low, but individuals with limited strength or mobility cannot safely access the trailer
Solution Approach 1:
The bracket device is designed with universal applicability to work with standard fold-out camper or trailer steps. The first and second mounting plates with their long and short arms can be attached to various trailer types, and the horizontal arms can support conventional fold-out steps. This multi-functional design enhances accessibility for individuals with limited strength or mobility while maintaining compatibility with existing step systems, avoiding the need for completely specialized equipment.

AI summary
A trailer step bracket designed for attachment to a flatbed trailer to support fold-out camper or trailer steps is disclosed. The trailer step bracket comprises a pair of symmetrical mounting plates, each featuring a long arm and a parallel short arm integrated (i.e., connected) by a transverse arm, with steps-supporting horizontal arms extending from the long arms. The horizontal arms are connected by a bracket disposed perpendicular (i.e., transverse) thereto and includes apertures for securing the fold-out camper or trailer steps. A detachable pivot member is fastened to the top surface of the bracket for accommodating a user's weight. The steps can be expanded or folded for ease of use. The bracket is constructed from durable material, such as steel or aluminum. Reflective strips may be added for visibility in low light conditions.
