Foldable MTB Ramp Assembly With Adjustable Height and Stable Grip

The ramp is divided into multiple modular sections that can be connected together. Each section maintains manageable dimensions for strength, while multiple sections combined achieve the required height for advanced jumps. The modular design allows distribution of structural loads across multiple connection points.

The ramp structure utilizes composite construction combining aluminum alloy frame with high-density polyethylene (HDPE) or marine-grade plywood surfaces. This composite approach provides both the strength required for high jumps and the durability for long-term usage, overcoming the limitation of single-material designs.

The ramp incorporates adjustable height legs with telescopic mechanisms that allow dynamic adjustment of ramp height and angle. The legs can be extended or retracted to various positions and locked in place, enabling the same ramp structure to adapt to different user skill levels and jump requirements while maintaining manufacturing simplicity through standardized components.

The ramp design allows modification of key parameters such as height, angle, and length through adjustable components. The height legs can be positioned at different elevations, and the ramp surface angle can be changed by adjusting leg positions, providing versatility without requiring multiple fixed-height ramp models.

The ramp frame is segmented into collapsible sections connected by hinge joints and locking mechanisms. When folded, the segments nest together in a compact configuration for easy transport. When deployed, the locking mechanisms engage to provide structural stability equivalent to non-foldable designs.

The ramp transitions between static (deployed) and dynamic (folded) states. In the deployed state, the frame maintains rigid stability for safe use. In the folded state, the same frame components are reconfigured into a compact, portable bundle, resolving the contradiction between stability and portability.
