Abstract
A roll-up closure device (Fig. 1) comprising a light weight flexible curtain (1), an extruded profiled edge (2), a synchronizing drive mechanism (3), a vertical retaining means (6) and a take up means (7). Said roll-up closure device eliminates the need for horizontal retaining mechanism positioned across the opening and the counter balance devices commonly associated with light weight flexible curtain roll-up closure devices as a means of preventing the curtain from being pulled out of the vertical retaining guides due to differential pressures that may exist in the closure device environment.
Description
FLEXIBLE CURTAIN CLOSURE DEVICE DRIVE AND CONTAINMENT
MECHANISM
SUMMARY OF THE INVENTION:
Said invention overcomes the Umitations and problems commonly associated with the atandard counter Valance devices an~i'iorizontal retainine mechanisms usc<i ~o light weight flexible curtain roll-up elos~.ire devices by incorporating an extruded profiled edge that is attached to the vertical edges of~a light weight flexible curtain, the extruded profiled edges in conjunction with a vertical retaining means then combine to form a horizontal tensioning and retaining mechanism for the light weight flexible curtain. A
synchronizing drive mechanism is then used to synchronize the closure device drive means to the closure device take-up means in order to control the light weight flexible curtains opening and closing as well as to maintain a vertical tension on the light weight flexible curtain. The application of these two methods combine to generate an efficient, safe and economical means of controlling the effects of differential pressures in the closure device environment.
FLEXIBLE CI1RTAIN CI,OSIJRE DEVICE DRIVE AND CONTAINMENT
MECHANISM
F1ELD OF THE INVENTION:
This invention relates to closure devices. A closure device being any mechanism or device used for the purpose of closing an opening. More particularly, the invention relates to light weight flexible curtain roll-up closure devices designed to close an opening by moving a curtain vertically up or down over the opening from a fully open position to a fully closed position or any intermediate position that may partially close the opening.
BACKGROUND OF THE INVENTION:
The fundamental benefits generally associated with lightweight flexible curtain roll-up closure devices are ease of maintenance and the resistance to damage due to impact or collision to both the closure device and the vehicle or persons involved.
It is common in light weight flexible curtain roll-up closure devices to use counter balance tensioning devices such as springs or weights, as a means of maintaining a vertical tension on the lightweight flexible curtain and controlling the opening and closing of the closure device. 'T'he use of such counter balance devices can render maintenance difficult, complicated and excessive.
It is also common in light weight flexible curtain roll-up closure devices to use a rigid horizontal retaining mechanism, such as a metal tube or bar, positioned across the opening as a means of preventing the lightweight flexible curtain from being pulled out of the vertical retaining guides due to differential pressures that commonly exist in the closure device environment. The use of such a horizontal retaining mechanisms can virtually negate the use of a lightweight flexible curtain closure device as a safe, impact or collision resistant closure device.
