Extension and retraction arrangements with control systems
First Claim
1. An extension and retraction arrangement with a control system for a monitor on a work surface comprising:
- a trolley structure;
a rail arrangement with a first end, a second end, and a body portion; and
a means for retaining the trolley structure in relation to the rail arrangement for axial extension and retraction along the body portion of the rail arrangement wherein the trolley structure has a retracted configuration wherein the trolley structure is disposed adjacent to the second end of the rail arrangement and an extended configuration wherein the trolley structure is disposed adjacent to the first end of the rail arrangement; and
a control system with an actuating arrangement and a means for selectively controlling a travel of the trolley structure in relation to the rail arrangement in response to an actuation of the actuating arrangement wherein the means for selectively controlling the travel of the trolley structure in relation to the rail arrangement comprises a means for mechanically engaging and disengaging the trolley structure in response to the actuation of the actuating arrangement comprising a first locking projection, a means for adjusting the first locking projection into and out of engagement with the trolley structure based on the actuation of the actuating arrangement, an actuating rod, and a first pivot member pivotally retained relative to the actuating rod wherein the first locking projection is retained for movement with the pivot member whereby an actuation of the actuating rod pivots the first locking projection of the first pivot member into and out of engagement with the trolley structure.

Abstract
An extension and retraction arrangement with a trolley structure retained for axial extension and retraction relative to a rail arrangement and a control system with an actuating arrangement and a mechanism for selectively controlling a travel of the trolley structure. In a manual control system, the trolley structure can be mechanically engaged and disengaged in extended and retracted configurations by first and second locking projections respectively. An actuating rod can be actuated by a trigger to pivot the locking projections into and out of engagement with the trolley structure. The trigger can additionally enable a selective release of first and second doors from closed positions. A motorized control system can propel the trolley structure and open and close the doors. A lock and key, an access card and access card reader, or a remote control and remote control receiver can selectively enable operation of the control system.

11. An extension and retraction arrangement with a control system for a monitor on a work surface comprising:
-
a trolley structure; a rail arrangement with a first end, a second end, and a body portion; and a means for retaining the trolley structure in relation to the rail arrangement for axial extension and retraction along the body portion of the rail arrangement wherein the trolley structure has a retracted configuration wherein the trolley structure is disposed adjacent to the second end of the rail arrangement and an extended configuration wherein the trolley structure is disposed adjacent to the first end of the rail arrangement; a first door with an open position and a closed position wherein the first door is pivotally retained adjacent to the first end of the rail arrangement; and a control system with an actuating arrangement, a means for selectively controlling a travel of the trolley structure in relation to the rail arrangement in response to an actuation of the actuating arrangement, and a means for selectively retaining the first door in the closed position and for selectively releasing the first door from the closed position in response to the actuation of the actuating arrangement wherein the means for selectively retaining the first door in the closed position and for selectively releasing the first door from the closed position comprises a door actuating rod in combination with a pivot member with a locking portion for engaging the first door wherein the pivot member is pivotally coupled to the door actuating rod whereby an actuation of the door actuating rod will induce a pivoting of the pivot member and a selective engagement of the locking portion with the first door. - View Dependent Claims (12, 13, 14, 15, 16, 17)
