My invention relates to conventional awning
type closure structures including a ?exible panel
and related frame elements and in particular
to such a structure having a bumper and pro
tector member.
The various disadvantages inherent in awn
ing structures of the type with which I am con
cerned result in excessive wear of the structural
elements. The conventional awning is difficult

that the closure structure will be rigidly and
securely held- in spaced relation to the adjoining
wall.

the inertia of the structure in moving to the open

In drop curtain type closure structures my im
provement functions as a protector and bumper
as well as a spacing means. The yielding nature
of the ?ange l3 on the protector and bumper
9 serves to protect the ?nish of the adjacent wall
and to absorb the shock as the drop curtain
structure strikes and scrapes therealong, as re
sults in moving the curtain to the open and
closed positions or when the curtain is subject
to wind currents and the like.
As in awning operation, the drop curtain 2|
may be secured in a substantially ?xed immov
able condition in the closed position by apply
ing additional tension on the operating cords or
ropes 25. After the operating means has rotated

In the drop curtain type closure structure 11-1
lustrated in Figure 6 of the drawing, it will be
obvious that my improvement functions as a pro
tector and bumper member as well as a spacing
means. As the curtain structure is elevated to
closed‘ position, the tensioned frictional engage
ment of the protector and bumper 9 with the
wall will maintain the curtain and associated
frame elements substantially immovable in a
manner similar to the operation of the drop cur
tain structure of Figure 5.
