Abstract
An apparatus can comprise a base mount, a linkage frame, a first linkage arm, and a second linkage arm. The linkage frame can include a first end and a second end; the first end of the linkage frame can be coupled to the base mount; and the linkage frame can include a cam plate positioned between the first end and the second end. The first linkage arm can include a first end and a second end; the second end of the first linkage arm can be rotatably coupled to the second end of the linkage frame; and the first linkage arm can include a cavity. The second linkage arm can include a first end and a second end; the second end of the second linkage arm can be coupled to the first linkage arm; and the second linkage arm can be positioned in the cavity of the first linkage arm. Other embodiments are disclosed.
