WINDOW CONTROLS

Window Controls - Hinged Window

Window controls: The need for controlling high level ventilation in buildings is universally appreciated, and wherever out of reach windows are incorporated there is a requirement for simple, economic and unobtrusive type of gear.

This is no longer a problem with the application of the wide range available. The advantages offered enable a number of high level windows to be opened and closed from a single operator, located in some cases a hundered feet away. The problem of difficult building contours is also overcome by the ability of the transmitting conduit to be had bent on site with the aid of a simple tool.

The system is based upon a unique form of cable having an over-wound helix wire to form a flexible rack.

This cable, enclosed in a rigid conduit, engages a suitably hobbed wheel in the operator and head unit, where in a push pull action, imparted by rotation of the handle, drives the mechanism to open and close windows. The line drawings shown below explain in some detail both priciple and typical application.
