Sweeney, Brentwood, Pittsburgh, Pa. ‘Application February 9, 1951, Serial No. 210,219 1 6 Claims. (Cl. 160-57) 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 2 . a closure protector and bumper member of such a resilient nature as to be deformed and com pressed against the side of the building as the closure is secured in inoperative position, so that the closure structure will be rigidly and securely held- in spaced relation to the adjoining wall. - ‘ A further object of my 7' invention is to pro vide a protector and ‘bumper member for an and troublesome in operation and as blasts of 10 awning structure eliminating “lodging” or “jam wind cause the frame and panel members to ming” of the frame and panel elements as the strike and wear against adjacent building sur closure is secured in inoperative position, thus faces, frequently, wear spots or holes usually insuring normal operation of the ‘structure un appear in the ?exible panel, the frame joints der the in?uence of gravity. become loose and the building ?nish may become 15 Another object of my invention is to provide a protector and bumper member for closures marred, thus detracting from its general appear ' ance.

Side panels '1 are secured to the top panel I as by stitching along the diagonal line 1 and may be provided with loops or the like along the lower edge for receiv ing the side arms 3 and 3'. The conventional awning includes suitable means to‘ elevate and lower the structure. Refer ring to Figure 1, ropes" or chains I5 are secured at one end to laterally spaced points [6 on the transverse rod 6 and are trained through pulley 4 zontally proportionately to the width of the awn ing panel. Additionally, the panel 3| is provided with a sleeve or pocket 33 for receiving 9, weight rod 34 and has hanging from this sleeve an addi tional section of fabric panel 36, which may be scalloped and bound in a manner similar to the bottom edge of the awning panel of Figure 1. For operating the curtain structure, ?exible means, such as ropes 31, are fastened to the weight rod 34 and are passedupwardly through the vertical rows of rings 32 and'suitable pulleys or eyes in a manner similar to that shown for the operating means in Figure 5. The free end of the operating ropes may be secured, as the awn members IT, IT’ and I8 securely mounted on'ithe' . window frame 5.

The resilient protector and bumper member 9, forming the important feature‘ of my invention, is? secured to extended end portions [0 (Figure 2) of the transverse‘ frame member 6 as shown‘ in detail in' Figure 4. In reference to‘ Figure‘. 4, the resilient protector ‘ - and bumper 9, made; of molded rubber, vinylite plastic, or other similar material comprises a tubular cap ll' for'attachment to the‘ tubular or rod-like‘extensions lll‘of the frame member 6 and same‘ toia cleateor.l the like in a manner such as indicated inFigure 1. In this type of drop curtain structure, the weight. rod 34 does not turn; the fabric panel My protector member, when applied to this form of drop curtain structure, spaces the panel 3| and weight rod 34 from the adjoining wall of the building and will eliminate wear on the panel, the ropes 31, and. the surfaces of the adjoining wall.

In an awning structure of the type‘ described the inertia of the structure in moving to the open position. 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 the transverse rod 20, winding the panel about the same, and the curtain has reached the limit .. of upward movement, additional tension on the cords or ropes 25 effects compression of the ?ange the combination of a ?exible panel having means at its upper edge for securing same to a build ing wall provided with an opening, a transverse 1y extending vertically movable frame member supporting the lower edge of said panel, ?exible operating means connected-to said member and the building wall for elevating said member to a position adjacent the building wall and above said opening therein and for lowering said mem ber to a position below the upper end of the open ing in the wall to cover the opening with said, panel, securing means for said ?exible operating means and yieldable contacting means compris ing a bumper disk secured to each end of said frame member for engaging the wall on opposite sides of said opening to hold the frame and panel members spaced therefrom. 3.

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.
