Abstract
ABSTRACT OF THE INVENTION
ROLL UP DOOR
A flexible roll up closure member, such as a roll up door, for an opening has its edges running in slots in side guide channels. The edges are extended so as to be unable to pass through the slots and a wire carrying a weight passes through each extended edge.
The closure member with its extended edges and the wire are able to be rolled into a roller.

DESCRIPTION
This invention relates to a closure for an opening, and has particular reference to a roll-up door suitable for use indoors in, for example, industrial :
- 10 buildings and the like.
. Door closures are known which are of the type in -~: which a flat member moves up and down across an aperture with the edges of the flat member ;;~
:constrained to move in channels or track members. In ~::
order to retain the edges within the channels ~ ~;
elements~of a dimension greater than the width of the ;~
. . . , .:; - .
~ ~ mouth of the channels have been secured to the edges - at ihtervals or along the whole of their length~
~It has also been pro~osed to provide~a door which is flex~ble~to the extent that if impacted by a vehicle .
it wLll allow the flat member to spring out of the ; . ~ ~ ~ . ,. . . :
the track members under a normal impact. While some elements operate successfully to retain the edges of rigid flat members in the channels, they cannot resist nor~al impact without damage being done to the S door by springing the door from the track members. It is therefore necessary to provide a method and means of retaining the edges of such flexible closures within the channels and it is an object of the present invention to achieve this.
According to the present invention, there is provided a closure for an opening which closure comprises a ~-pair of track members in spaced parallel relationship one with the other, each of said members being hollow ~-and having a longitudinal slot extending from at least one end thereof in the plane of the opening, ~ roller means disposed between said members and in - -~uxtaposition with said one end thereof, a closure member adapted to roll and unroll on said roller means, each side edge of which enters the ., longitudïnalislot in ia track member for sliding relationship therein,~
retaining means provided at the edge of the -~
closure member adapted to move within the hollow ;;~ ~
: : , `,;':' `: :
portion of each track member to prevent removal of the edges of the closure member laterally therefrom at least under the influence of normal impact forces on the closure member itself, said retaining means being rollable with said closure member on said roller means, and said retaining means comprising a loaded element located in a surrounding section at the edge of the closure member.
lû :'''- ~' The retaining means may be comprised by folding the ;
edge of the closure member to form the surrounding section at the edge of the closure member, or alternatively a separate surrounding section may be fixed to the edge of the closure member.
The loaded element may be a wire or a like - longitudinally extending flexible element and may be ~positioned along the centre of the track member. The element is preferably loaded with a weight. A
stiffening member may be provided at the bottom of ~;
the closure member and the stiffening member can ~- -. . . ~

a rigid profile of the bottom end of the door-leaf to keep the door-leaf in a stretched condition during movements of opening and closing of the door-leaf, and when the door is closed.
