Abstract

Embodiments of the inventive subject matter are directed to vertically stabilized platforms. These platforms have a top portion that moves only along a single axis (e.g., vertically up and down), and a bottom portion that remains stationary relative to a reference frame. The top portion is coupled with the bottom portion by scissor linkages that are all configured to slide on one end to allow the top portion to move up and down without any perturbations or movements along any other axes. Stabilization in some embodiments is accomplished by incorporating struts that couple with both the bottom portion (either directly or indirectly) and two of the scissor linkages. Struts can include both a damper and a spring and can be selected based on anticipated load to be stabilized. Embodiments can be mounted on, e.g., truck beds, ships, or other surfaces that can move, giving rise to a need for a stabilized platform.

Dependent claims

A stabilized platform comprising:

a top frame comprising a top guide rail;
a bottom frame comprising a bottom guide rail;
a top-sliding scissor linkage comprising a first pin joint at a bottom end of the top-sliding scissor linkage and a first sliding block at a top end of the top-sliding scissor linkage;
wherein the top-sliding scissor linkage couples with the first sliding block by a first sliding block pin joint;
wherein the first sliding block comprises a first elongated slot that is complementary to the top guide rail;
wherein the first pin joint couples with the bottom frame and the first elongated slot slidably couples with the top guide rail;
a bottom-sliding scissor linkage comprising a second pin joint at a top end of the bottom-sliding scissor linkage and a second sliding block at a bottom end of the bottom-sliding scissor linkage;
wherein the bottom-sliding scissor linkage couples with the second sliding block by a second sliding block pin joint;
wherein the second sliding block comprises a second elongated slot that is complementary to the bottom guide rail;
wherein the second pin joint couples with the top frame and the second elongated slot slidably couples with the bottom guide rail;
wherein the top-sliding scissor linkage and the bottom-sliding scissor linkage are coupled by a third pin joint;
a bottom strut cross member coupled with the bottom frame;
a top strut cross member coupled with the top-sliding scissor linkage;
and
a strut coupled with the bottom strut cross member at a first end and with the top strut cross member at a second end.
