lumbns, Ohio, assignor to General Door Company, Reno, Nevada, a corporation of Nevada 8 Claims.

This invention relates to rolling door structures and particularly to doors having curtains adapted to be rolled up on drums or similar apparatus.

One object of this invention is to provide a rolling door having a curtain consisting of a reticulated structure, the members of which are hinged relatively to one another so as to be capable of being rolled up on a drum or similar member and unrolled to close the door.

Another object is to provide a rolling door having a curtain consisting of a plurality of rod-like members interconnected by lattice members and hinged relatively to one another so as to form a reticulated curtain.

Another object of this invention is to provide a curtain for a rolling door, consisting of a series of short shouldered rods interconnected horizontally by bars forming a diamond-shaped structure, the upper and lower ends of which are pivoted upon rods running the entire width of the door. 1

In the drawings:

Figure 1 is a front elevation, partly in section,

of the rolling door of my invention, showing the door in its lowered position; 7

Figure 2 is an enlarged vertical section through the door of Figure 1, taken along the line '2-2 thereof;

Figure 3 is an enlarged detail view of a portion of the curtain;

Figure 4 is a section along the line 4-4 of Figure 3; r

Figure 5 is a section along the line 5-5 of Figure 1, showing the edge of the curtain and the guiding member therefor.

Referring to the drawings in detail, Figures 1 and 5 show a wall 10 having an opening I l for the reception of a door. Secured to the wall on each side of the door opening H is an angle member 12, as by the bolts 13. To each angle member 12 is secured a channel member M with the opening thereof facing inwardly. The opening is partly closed by flanges I5. These flanges serve the purpose ofretaining the sides of the curtain in lateral alignment, and yet permit the curtain itself to pass between them. To the wall above the opening 11 are secured frame members It, as by the bolts 11. (See, for instance, Figure 1). These frame members serve to support the shaft 18 and the rotatable drum I9, upon which, the curtain hereinafter described is rolled when the door is opened. Any suitable means may be provided for rotating the drum H) in order to wind up or lower the curtain. These mechanisms are well known to those skilled in the art and form no part of the present invention.

Also arranged above the door opening I l and positioned to conceal and protect the mechanism 5 is a hood 2i]. This hood encloses the drum l9 and the adjacent working parts.

Secured to the drum I9, as by the rivets 2|, are links 22, by which the curtain, generally designated 23, is secured to the drum [9. The curtain 23 consists of a plurality of side plates 24, the upper ends of which are offset, as at 25, to permit the adjacent side members 24 to be placed in alignment with one another. The extremities of each side plate 24 are bored, as at 2.6 and 21, 15 to receive hinge rods 28 passing therethrough and serving to tie the side plates 24 together. Pins 28' serve to retain the side plates 24 upon the hinge rods 28. The lowermost hinge rod '28 is provided with a straight side plate 29, secured 20 as by welding to the bottom member 30 of the door.

The bottom member 30 is preferably of T- shaped cross section (Figure 4) and is provided with angled members 3| secured thereto and serving as handles for assistance in raising the door manually. Secured at intervals along the bottom member 30 are links 32, whose upper ends are provided with bores 33 encircling the lowermost hinge rod 28. The mid-portion of each side plate 24 is provided with a hole 34 which serves to receive the end of short end rods 35, the opposite ends of which are secured in similar holes 36 in a lattice or connecting member, generally designated 31, having a central portion 38, angled intermediate portions 39 and end portions it and 4!, which are substantially parallel to the middle portion 38. The opposite ends of the short end rods 35 are secured to their

respective members

24 and 31 by any suitable means, the 40 means shown being that of offsetting the ends to form an enlarged portion similar to the head of the rivet.

It will be seen that the ends of the short rods 35 are slightly reduced in diameter at the points 45 where they pass through the holes 34 and 36, the annular shoulders formed thereby serving as abutments to position the end rod 35 between the side member 24'and the lattice member 31. Arranged in alignmentwith the end rods 35fare ,50 other shortrods 42 serving as tie members and secured at their ends to similar lattice members 31. 'The adjacent lattice members 31 face one another so as to form a roughly diamond-shaped aperture therebetween. .The lower end portions 455 40 of the lattice members 31 are bored, as at 43, to receive the hinge rod 28, and are arranged on opposite sides of each link 32, the latter being bored, as at M, to receive the hinge'rod 28. The upper ends B! of the lattice members 31 are similarly bored, as at 45, and are positioned to engage one another face to face, the adjacent lower ends 40 of the lattice members 37 thereabove being placed on the outer sides thereof (Figure 3). Thus the upper ends ll of each lattice member 31 serve as spacing members for the lower ends Ml of the lattice members immediately above. Also the various rods and 52, in conjunction with the lattice members 3i and the hinge rods 28, form a reticulated curtain having hinged side plates 24 on each Vertical edge thereof. The

rods

32 and 35 with their lattice members 31 form rigid units extending from one side of the curtain to the other, each rigid unit being hinged above and below its

rods

42 and 35. The vertical edges of the curtain slide in the channel member l4 and are prevented from withdrawal by the flanges 15 thereof.

In the operation of the rolling door structure of this invention, assuming the parts to be in the closed position shown in Figure 1, the door is opened by causing the drum ii) to be rotated by suitable power mechanism. This mechanism may be operated either by power or manually in ways well known to those skilled in the art. As the drum l9 rotates, the links 22, secured thereto, travel circumferentially around the shaft l8, and the side plates 2d, which are connected to the links 22 and to each other, are wound up on the rotating drum H! in the manner shown in Figure 2.

Each horizontal unit composed of the rods 35 and t2 and the lattice members 31 hinges at its upper and lower extremities on the hinge rods.

28 and is deposited upon the periphery of the rotating drum i9 as it reaches that location.

As the curtain is wound up on the drum, the bottom member 38 passes the top 35 of the opening I! and enters the aperture 51 between the lower edge of the member 58 supporting the hood 20 and the opposing lower edge of the member 49, the latter being secured to the wall In by the bolts 56. When the door is in its topmost position, the bottom edge of the bottom member 39 closes the aperture H. To unwind the door and close the opening, the foregoing operations are reversed, the drum i9 is rotated in a counterclockwise direction and the various side members 24 disengage themselves from the periphery of the drum H3; The side members 24 and hinge rods 28 pass downwardly within the channel member It untilthe bottom member 30 rests upon the ground or door sill, thus closing the opening.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of the claims and the invention.
