Abstract

A monitor stand with a base, a first linear motion stage, a second linear motion stage, and a monitor mount. The first linear motion stage attaches to and extends away from the base and has a first end attached to the base, a second end, and a first linear guide extending between the first end and the second end. The second linear motion stage is attached to and extend away from the first linear motion stage and has a first end attached to the second linear motion stage, a second end, and a second linear guide extending between the first end and the second end. The monitor mount is fixed to the second end of the second linear motion stage and is configured to attach to and support a computer monitor. One of the first linear motion stage and the second linear motion stage comprises a horizontal Sarrus linkage.

Dependent claims

A monitor stand, comprising:

a base configured to mount to a horizontal surface;
a first linear motion stage attached to and extending upward from the base, the first linear motion stage comprising a first end of the first linear motion stage fixedly attached to the base, a second end of the first linear motion stage positioned above the first end of the first linear motion stage, and a vertical Sarrus linkage extending between the first end of the first linear motion stage and the second end of the first linear motion stage, the vertical Sarrus linkage having a plurality of pairs of links joining the first end of the first linear motion stage to the second end of the first linear motion stage in parallel, each of the plurality of pairs of links comprising two rigid plates coupled together with a hinge;
a second linear motion stage attached to and extending forward from the first linear motion stage, the second linear motion stage comprising a first end of the second linear motion stage fixedly attached to the second end of the first linear motion stage, a second end of the second linear motion stage positioned forward from the first end of the second linear motion stage, and a horizontal Sarrus linkage extending between the first end of the second linear motion stage and the second end of the second linear motion stage, the horizontal Sarrus linkage having a plurality of pairs of links joining the first end of the second linear motion stage to the second end of the second linear motion stage in parallel, each of the plurality of pairs of links comprising two rigid plates coupled together with a hinge;
a monitor mount fixedly coupled to the second end of the second linear motion stage and configured to attach to and support a computer monitor;
and
a spring extending between the first end of the first linear motion stage and the second end of the first linear motion stage, wherein the spring is configured to exert an upward force on the second end of the first linear motion stage and counteract a weight of at least the second linear motion stage, the monitor mount, and the computer monitor;
wherein the vertical Sarrus linkage is configured to enable adjustment of a vertical position of the monitor mount with respect to the base;
and
wherein the horizontal Sarrus linkage is configured to enable adjustment of a horizontal position of the monitor mount with respect to the base.
