Branched scissor linkage and associated auxetic mechanisms

Branched variants of the scissor mechanism but with multiple arms

• Multiple arms, joined by a branched rivet allows 3D movement

Benefit

The scissor mechanism variant allows for nearly infinite shapes and structures. The structures can be collapsed into a compact shape then deployed into a large, functional shape.

One embodiment is an extendable, grasping device.

Market Application

• Toy market.
• Space applications where compactness is important for lift off, but then deployment of a larger shape with structural integrity is possible.
