An arm for supporting a monitor comprises a telescoping arm assembly, a support member and a cord storage device. The telescoping arm assembly has at least first and second telescoping members telescopingly movable relative to each other, a distal end configured to support a monitor and a hollow interior through which at least one cord from the monitor can be routed. The support member is connected to the telescoping arm assembly proximally of the distal end to suspend the telescoping arm assembly. The support member is configured to extend transverse to the telescoping arm assembly and to be attached to a support surface. The cord storage device is positioned at least partially within at least one of the telescoping arm assembly or the support member. The cord storage device winds and unwinds the cord from the monitor as the first and second telescoping members are moved toward and away from each other, respectively.

Described herein are various embodiments of a dental delivery system. For example, in one exemplary embodiment, a rear dental delivery system through which at least one of water, air and vacuum are delivered for use by a care giver in treating a patient occupying a nearby dental chair can include at least one movable arm that is pivotably mounted to a pivot connection and an upright mounted to the at least one movable arm. The pivot connection can be mounted at approximately a floor level and the at least one movable arm can be configured to pivot slightly above the floor level so as to reduce obstruction in a space separating the dental chair from the dental delivery system.

A system for reconfigurably adapting a dental chair for use, including, e.g., use from the right side or left side, use by right-handed or left-handed practitioners and use in various dentistry practice styles, may include a link arm, a primary arm and a secondary arm. The link arm is pivotably connectible to a rear side of the dental chair. The primary arm is pivotably connectible to the link arm to swing in a generally horizontal plane about a generally vertical axis. The secondary arm is coupleable to the link arm, preferably along substantially the same axis. The secondary arm has multiple pivotably connected segments allowing its distal end to be positioned as desired.

The linkage assembly provides an adjustment mechanism for adjusting the effective length of a rod member pivotally attached between two posts. The adjustment mechanism reduces the need for small-tolerance pivot hole locations in the assembly and permits compensation for arm sag that is attributable to deflection or other factors.

A telescoping arm has a rod slidable within a sleeve defining an interior bore. A bushing attached to the rod slides within the bore and has a substantially rigid block constrained by the bore against substantial rotation or lateral movement. The bushing further includes a spring portion biased against the sleeve to provide frictional resistance to telescoping of the apparatus and to prevent the bushing from rattling in the bore. The spring responsively accommodates small lateral and rotational forces, while the block bears more substantial loads.
