A recently granted patent (Publication Number: US11820629B2) discloses a grabber designed for lifting and lowering blocks. The grabber includes one or more arms with a damped self-centering mechanism at the distal end to dampen contact forces and facilitate self-centering relative to the block's surface. This mechanism consists of leaf springs arranged circumferentially around a support member, deflecting to absorb contact forces effectively.

Furthermore, the grabber features levers in the distal portion of the arms that can be actuated between retracted and extended positions, allowing engagement with the block. The damped self-centering mechanism extends past the block's bottom surface when coupled, enhancing stability. The arms may be tubular, and the leaf springs can have a linear or curved body, forming a convex shape to optimize deflection. Additionally, the leaf springs can be stacked and coupled with clamps, deflecting independently to improve performance. Overall, this patented grabber offers a sophisticated solution for lifting and lowering blocks efficiently and securely, with a focus on dampening contact forces and ensuring self-centering during operation.
