2 (Ilaims. (Cl. rec-12o)- This invention relates to closures and, more particularly, to rolling doors.
Many new uses have been found for flush mounted type sliding and rolling doors. In some instances, it has been found to be extremely desirable to provide such flush type rolling doors in hotel lobbies, theatres, banks, and the like, whereby it becomes important to the maintenance of the proper decor to provide a neat and finished appearance that will readily blend with the architectural construction of the building. It is therefore an object of the present invention to provide a rolling door installation that is extremely simple in construction, simple to operate, and which provides a completely finished and neat appearance.
Another object of the present invention is to provide a rolling door having guide members that are smooth and free from projections to enable the curtain to slide freely in an even and uninterrupted motion.
A further object of the present invention is to provide guide means for the curtains of rolling doors that will effectively reduce friction, noise, and derormation of the curtain slats, and which will facilitate the opening and closing thereof.
A further object of the present invention is to provide a self-contained locking mechanism within the curtain that is completely hidden from view and which can be manually actuated to retain the curtain in a closed position.
Another object of the present invention is to provide a completely self-contained rolling door installation that can be readily applied between the jamhs of a wall opening, or upon the face side thereof, without necessitating any structural changes in the supporting wall or surrounding equipment.
Still another object of the present invention is to provide a rolling curtain type door embodying a removable mullion which will enable such doors to be readily installed in exceptionally long wall. openings without excessive strain upon the parts or deformation due to the weight of the curtain that might otherwise result.
An additional object of the present invention is to provide cooperating locking elements that maintain the end posts, mullion, curtain, and storage roll housing in properly connected operating relationship at all times com-' pletely independently of the wall within which the door is mounted so as to enable such doors to be readily installed. within any wall opening without requiring structural changes in the opening defining portions of the wall.
Still a further object of the present invention is to provide a rolling door unit of the type described that presents a completely uniform and clean exterior appearance, devoid of objectionable fasteners, unsightly irregular portions, and which includes security locking elementsthat are all completely hidden from view.
Another object of the present invention is to provide a rolling door of the above type that is-constructed from a plurality of extruded shapes that slidably interlock with each other to produce the necessary components thereof, thus reducing the number of additional fastening elements required to maintain the parts in proper position and reducing the cost of manufacture of the finished door.
All of the foregoing and still further objects and advantages of this invention will become apparentfrom a study of the following specification, taken in connection with the accompanying drawing, wherein:

Referring now to the drawing, and more particularly to FIGURE 1 thereof, a rolling door installation 20 made in accordance with the present invention is shown in operative association mounted between the jambs defining an opening in one side of a walled enclosure 21. This installation 201s a multiple curtain unit having a removable mullion, as will hereinafter be more fully explained.
With more specific reference now to FIGURES 2 and 3 of the drawing, a longitudinally flexible and transversely rigid curtain 22 forming a part of the present invention is shown to be constructed from a plurality of preferably extruded aluminum slats 23. One side edge of each slat 23 is provided with a bead 24 that is pivotally received within the female socket 25 formed along the opposite edge of the next adjacent slat. Each bead24 is slidably received within the adjacent-female-socket of the next adjacent slat, thus enabling the slats to be assembled without the use of additional fastening elements. However, in order to maintain the slats in proper alignment with each other, end locks 2'7 are secured, such as by rivets 28, to alt rnate slats 23, thus blocking the outward movement of the adjacent bead. 2-4 through the end of the closed socket 25.
End posts arranged in accordance with one embodiment of the present invention, are shown more clearly 1n FZGURES 5 and 6 to be constructed from two extruded. shapes, a base part 31 and a guide part 35. The base part 31 defines a longitudinal groove 32 that slidably receives a rail 33 of the guide part 35, so as to enable these twoparts to be slidably connected together as a single integral unit. The guide part 35 defines a longitudinal groove 36 into which the adjacent end of the curtain 22 is slidably received. An anti-friction track 37, such as extruded nylon, of substantially trapezoidal cross sectional configuration is slidably received within a similarly shaped groove adjacent to the longitudinal groove 36 of the guide part 35. This track slidably engages the inside surface of the curtain 22 so as to guide it during its longitudinal movement with a minimum amount of frictional resistance. An arcuate guide member 33 also having an anti-friction track element 39 has a depending stem 40 that is received within a socket 42 at one longitudinal end of the guide part 35 of the end post, and secured thereto by means of a screw 41. As is clearly shown in FIGURE 5 of the drawing, mounting bolts 44 are extended through both the guide part 35 and the base part 31 of the end post into securing engagement with expansion bushings 45 disposed in the jamb or wall 43 so as to rigidly secure the end post in place. Since these mounting bolts are on the rear side of the curtain, the front side thereof is completely neat and smooth, completely devoid of any attaching or fastening elements that might otherwise detract from its appearance.
Referring now to FIGURES 4, 7, and 8 of the drawing, a storage unit for receiving the rolling curtain in a storage position is shown to be an integral part of the end posts and associated guide means. End plates 47 are secured, such as by mounting bolts 48 that extend through provided openings 49, to the jamb or wall 43 directly above and in alignment with the base part 31 of the end posts. Each such end plate 47 has a spacer flange 51 that maintains the end plate in properly spaced apart relationship upon the jamb i3. Cylindrical spacers through which the mounting bolts 48 extend further assist in maintaining the end plate 47 in properly spaced relationship with the wall or jamb. Attachment flange 52 in front provides means for securing apron 69 when the door is mounted under a lintel. When the door is mounted on the face of a wall, flange 52 is used to fasten plate 47 to the wall. This hood is shown to include an angular bottom and back plate 59, a top plate 53, and a front apron 6i). Angular mounting brackets 61 longi tudinally spaced apart throughout the length of the hood provide means for securing the respective plates in proper position relative to each other and the supporting end posts 36. It will be noted that each arcuate guide 38 projects upwardly through the opening 63 between the apron 6i) and the facing edge of the bottom plate 59 so as to guide the curtain upwardly therethrough into rolling engagement with a supporting roller 64 of any desired construction. This roller 64, which may include a torsion spring for assisting in the raising and lowering of the curtain, forms no part of the present invention and is thus not illustrated in further detail. Suflice it to state that such roller 64 may be of any desired construction which will enable the curtain 22 to be rollably supported thereon. In all longitudinal movements of the curtains 22, the end posts 30 serve to guide the curtain smoothly and evenly into engagement with the roller. Security lock plates 6-6, as is more clearly shown in FlGUlZE 5 of the drawing, extend behind facing shoulders 68 in the 4- guide part 35 of each end post to prevent canting of the curtain and tran verse relative movement thereof. During the installation of the unit, the curtain is assembled with the end posts merely by sliding the curtain into engagement therewith, within the respective channel openings 31'.
The removable mullion 7t! is more clearly illustrated in FIGURES 9 through 12, and is shown to basically include a pair of end post sections that are secured in back to back relationship with each other by means of nut bolt assemblies 76. Each such section includes a base part '73 and a guide part 74 that has a frictionless track 75 that functions in a manner similar to that hereinbefore described. The muilion 76 further includes releasable means for lockin" it in place during the raising and lowering of the curtain, but which permits it to be removed from the window opening when the curtains are in the raised position illustrated in FIGURE 13 of the drawing. Such locking means includes a handle 77 that has a stem 73 projecting into the interior of the base part 73 of each section through a longitudinal slot 79. A block 81 slidably supported within the channel defined by each base part 73 is secured to the opposite end of the handle stem 78 so as to be longitudinally movable therewith throughout the length of the slot 79. A set of spring fingers 82 secured to this block 81 frictionally resist movement of the block 81 between positions. However, longitudinal movement of the block 81 by means of the handle 77 is operative to etiect similar longitudinal movement of an inside rod 84 that has a wedge block 850, 12 secured to the opposite end. One such wedge block 35a is movable longitudinally into a channel guide upon which an end plate it for the curtain storage hood is attached. The other wedge block 8% has a depending pin 85 that is receivable within a well 87 in the counter top 83 of the walled enclosure. Thus, with both handles 77 moved toward their outermost positions, the wedge blocks 85a, I) serve to lock the mullion in place within the window opening. By retracting these handles 77, which are accessible only from the interior of the Walled enclosure, the mullion can be unlocked so as to be removed after the curtains 22. have been ra'ed to the open position, thus opening the walled enclosure Zita for use. The upper end of each guide part 74 of the mullion is also provided with an arcuate guide member 92 similar to that hereinbefore described for guiding the curtain upwardly into rolling engagement with the supporting roller 64.
Each curtain 2.2 is further provided with a bottom lock bar 1% that includes an extruded face plate 161 having longitudinal grooves Hi3 that slidably receive a back plate 185 therewithin. Rivets secure the back plate 195 in properly aligned position with the face plate 101 so as to define a longitudinal housing therewithin. Each side edge of the face plate 161 is provided with a socket 168 for receiving the male bead 24 of the outrmost one of the curtain slats 23 on one side, and an astragal 109 on the other side that functions as a seal for snug fit engagement with the counter top 88. Resilient bumpers ill secured to the inside surface of the bottom lock bar limit the upward movement of the curtain so as to prevent it from moving completely within the hood assembly, so that it is always accessible for movement toward a closed position. Since the bumpers 111 are larger than the opening 63 into the hood, they eifectively prevent continued movement of the terminal portion of the curtain thercthrough.
A lock assembly made in accordance with one form of the present invention is more clearly illustrated in FiGURES 2, 3, and 1 of the drawing. This assembly includes a housing 115 that is recessed within the rear side of each end of the bottom lock bar 100. A slide bolt H3 is slidably supported within each such housing 115, and has one end of a lock bar 119 secured thereto, such as by a rivet 12:3. The opposite end of each such lock bar 119 is slidably supported within a slot 121 within the end plate 122 of the lock bar 100. Thus, in response to sliding movement of the bolt 118, the lock bar 119 can be selectively moved into and out of an aligned opening 124 in the lowermost portion of each end post or mullion, thus locking the bottom bar 100 and the rest of the curtain against longitudinal movement relative thereto. This housing 115 is accessible only from the interior of the enclosure 20, so that it does not detract from the finished appearance on the outside thereof. If desired, a padlock or other retaining means may be extended through aligned openings in the handle part of the sliding bolt 118 and a cross bar 116 of the housing 115 to prevent unauthorized opening of the curtain.
In FIGURES and 16 of the drawing, a slightly modified form of lock assembly 130 is shown to include a single cylinder lock 131 mounted upon the bottom lock bar 100, such as by rivets 132. This cylinder lock 131 includes a shaft 134 to which a cross arm 135 is secured, such as by a key 136. One end of a lock bar 137 is secured, such as by means of a pivot pin 138 to each end of the cross arm 135. Thus, in response to rotation of the cylinder lock 13 1, the lock bars 137 are simultaneously moved inwardly and outwardly through aligned slots 140 in the end plates 139 at the opposite ends of the bottom bar 100, into and out of engagement with similarly aligned slots 142 in the end posts and mullion. In this embodiment, a single rotation of the cylinder lock 131 is operative to lock and unlock both sides of the bottom lock bar 100.
As shown in FIGURE 5a, a substantially wider base post 3111 is used in connection with the channel guide post 35 with doors operated by crank where greater clearance is required on one side to provide necessary space for the operating device. During such installation, a substantially longer mounting bolt 44a is required to secure the assembled post 30a to the wall or jamb 43.
With reference now to FIGURES 17 to 19, an installation 150 is shown that is mounted upon the inside face of a wall 152 that defines an opening 151 through which access is to be controlled. In this embodiment, the mounting bolts 153 extend through aligned openings 154 in both the base part and guide part of the end posts so that the curtain overlaps the openings defining portions on the inside of the wall. In this arrangement, auxiliary mounting holes 49a in the flange 52 of the hood end plates are used to mount the hood upon the wall completely hidden from view. The universal and symmetrical construction of the related parts enables this rolling door to be equally as well installed between the jambs or upon the face of the wall, to suit any desired purpose.
While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the claims appended hereto.
