Support arm

摘要

A support arm includes a generally elongated support arm housing having first and second ends; an arm mounting member pivotally carried by the first end of the support arm housing, the arm mounting member pivotal throughout a first range of rotation; a device mounting member pivotally carried by the second end of the support arm housing, the device mounting member pivotal throughout a second range of rotation; a position equalizing assembly engaging the arm mounting member and the device mounting member, the position equalizing assembly pivoting the arm mounting member and the device mounting member in opposite directions throughout the first range of rotation and the second range of rotation; anda counterbalance adjusting assembly carried by the arm mounting member and engaging the device mounting member, the counterbalance adjusting assembly applying counterbalance force to the device mounting member.

1. A support arm mounted on a support structure for supporting an electronic device, comprising:
a generally elongated support arm housing having first and second ends; at least one proximal ball bearing assembly and at least one distal ball bearing assembly carried by the support arm housing; at least one proximal housing shoulder bolt and at least one distal housing shoulder bolt carried by the at least one proximal ball bearing assembly and the at least one distal ball bearing assembly, respectively; an arm mounting member pivotally carried by the at least one proximal housing shoulder bolt at the first end of the support arm housing, the arm mounting member pivotal throughout a first range of rotation, the arm mounting member including an arm mounting member wall outside the support arm housing, the arm mounting member wall forms an arm mounting member interior, and an arm mounting member bottom panel closing the arm mounting member interior, the arm mounting member interior open opposite the arm mounting member bottom panel; a device mounting member pivotally carried by the at least one distal housing shoulder bolt at the second end of the support arm housing, the device mounting member pivotal throughout a second range of rotation, the device mounting member including a device mounting member wall outside the support arm housing, the device mounting member wall forms a device mounting member interior, and a device mounting member top panel closing the device mounting member interior, the device mounting member interior open opposite the device mounting member bottom panel; a position equalizing assembly engaging the arm mounting member and the device mounting member, the position equalizing assembly pivoting the arm mounting member and the device mounting member in opposite directions throughout the first range of rotation and the second range of rotation; and a counterbalance adjusting assembly carried by the arm mounting member and engaging the device mounting member, the counterbalance adjusting assembly applying counterbalance force to the device mounting member.
