Carlo, Dnbuque, Iowa, assignor to Duhuque Products, Inc., Dyersville, Iowa, a corporation of Iowa Filed Dec. 16, 1960, Ser. No. 76,212 6 Claims. (Cl. 160-23) This invention relates to buildings and to the construction of the same including the arrangement of the walls which subdivide the interior into rooms or areas, and of an appropriate size for the desired use or accommodation.
The invention relates particularly to buildings having walls or partitions which, in a minimum of time and effort, may be modified and after the need for the same has been ended the building can be restored to its original condition.
Buildings of many sizes have been provided with movable Walls or partitions; however, these movable walls have been massive, heavy, and unwieldly, as well as unsatisfactory and expensive, have not provided a solid or satisfactory barrier and their use has been difiicult and has involved too much time and effort.
It is an object of the invention to overcome the difiiculties enumerated and to provide a simple practical and relatively inexpensive wall or partition, which can be easily manufactured, at relatively small cost, readily installed, used and removed in a minimum of time and with a minimum of effort and expense.
Another object of the invention is to provide a movable wall or partition which when not in use can be contained in a relatively small space from which it can be readily withdrawn and into which it may be readily disposed with mechanical means by which the movement of the wall structure may be put into use or withdrawn therefrom.
A further object of the invention is to provide a coilable partition, a holder therefor and operating means including a coil box or holder and power means for coiling and uncoiling said partition.
Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing wherein:

Briefly stated the present invention comprises a coilable partition having one or more non-coiling doors providing access from one side of the partition to the other, means for supporting the coilable partition, and means whereby a portion of the free end is removed to accommodate a projection and with the remaining portion of the free end coilable within the coil box. In the first modification of the invention the free end of the partition has a piano type hinge mounting a non-coiling portion of the partition which has a passageway or door located in its lower portion and means for maintaining the noncoiling portion of the partition Within the coil box when the partition is retracted and coiled. In a modified form of the invention an opening is provided intermediate the ends of the partition and such opening is adapted to be closed by a door suspended from a track adjacent the partition and such door is adapted to be received within the coil box when the partition is retracted and to be extended by the partition when the partition is extended. A further modified form is provided so that the lower portion of the free end of the partition can be cut away to accommodate an obstacle such as a grandstand and supporting means is provided for the free end of the partition in the coil box. The partition is suspended from an overhead track and is provided along its lower edge with restraining means to prevent lateral movement and to support the individual slat like members of such partition.
With continued reference to the drawings, a coil box or holder 10 is provided in which a coilable partition 11 is adapted to be mounted for projection and retraction by mechanism such as that disclosed by copending application 783,295.
The partition 11 includes a series of interfitting strips or slats or slat like members 12 of wood or other material having a tongue 13 along one edge and a recessed tongue receiving groove =14 along its opposite edge. Each slat has a shoulder 15 adjacent to the tongue 13 along one side thereof and an offset shoulder 16 along the opposite side so that the partition can be coiled in one direction but cannot be coiled in the opposite direction while the tongue and groove remain in cooperative engagement.
Each of the slats has a recess 17 in its upper edge and a recess 18 in its lower edge with a flexible tape 19 retained within such recesses and fastened to some of the slats by a rivet or other fastener "20 to maintain such members in close interfitting relation. The tape 19 is preferably fastened to approximately every 9th slat with the intermediate slats loosely held to allow for expansion and contraction of the slats without binding and without spaces between them.
A slidable member or shoe 21 has a transverse offset recess forming portion 22. in its upper portion and the lower portion 23 is longitudinally offset to provide a shoulder 24 at one side and a notch 25 at its opposite side. The shoe 21 is fixed in the lower recess 18 of each slot by rivets 26 or other fastening means and by the rivets 20 which fasten the tapes 19 to some of the slats, the tape 19 being disposed within the recessed portion 22.
A series of hangers 28, similar in construction to the shoes 21, are selectively located in the upper recesses 17 of some of the slats. The hangers 28 have transverse recessed portions 29 and longitudinally ofiset portions 30 and are secured within the upper recess 17 of selected slats by rivets or other fasteners 31 with the tape 19 disposed in the recessed portion 29. The offset portion 31 has an opening 32 in which the reduced portion 33 of a shaft 34 is attached and a roller 35 is mounted on the opposite end of the shaft 34 and such roller is located within a generally U-shaped track 36 from which the coilable partition is suspended. It is noted that the hangers 28 are equally spaced along the top of the parti- 3 tion and the intermediate slats are supported by the offset portion of the shoes 21. This is accomplished by the notch of one shoe resting on the shoulder 24 of the adjacent shoe and the shoe which is thus supported will provide a support for the next shoe.
The U-shaped track 36 is mounted in a frame 37 on the top of which is secured a bracket 38 having outwardly extending wings or projections 39 and such wings are adjustably supported by lock nuts 46 and bolts 41 which in turn are supported by a structural member 42 which forms part of the building. If desired the supporting structure may be enclosed within a housing 43 which projects downwardly below the level of the ceiling tocover the supporting structure.
In order to prevent the partition from being moved transversely the shoes 21 are retained within a slot 44 formed by a pair of strips 45 supported on brackets 46 within a U-shaped channel 47 recessed within the floor. The strips 45 preferably are located in substantially the same plane as the floor of the building.
The free end of the partition 11 terminates in a retractable non-coiling door including a pair of jarnb forming strips 50 and 51 separated by a lintel 52. The area above the lintel 52 is closed by interfitting slots 53 similar to but somewhat shorter than the slats i2 and the area below thelintel is adapted to be closed by a passage closure or door 54 connected by hinges 55 to the strip 51. If desired, the door 54 may have a conventional operating latch and lock (not shown) or may be freely swingable.
The leading edge of the strip 50 is provided with a flexible bumper having a resilient covering 61 covering the same and being attached to the strip in any desired manner as for example by fasteners 62. The non-coiling door partition is mounted on the coilable partition by a piano-type hinge 63 connecting the strip 51 to a similar strip 64 on the coilable partition.
The track 36 which supports the coilable partition also supports the non-coiling door partition. In order to do this the track is provided with a double rail and the supporting rollers 35 of the coilable partition engage the track in the direction the partition is coiled. The portion of the track which supports the partition is omitted inside of the coil box 10 and the partition passes a guide roller 65 (FIG. 11) mounted in any convenient manner on the coil box structure and is coiled about a post 66. The portion of the track which supports the non-coiling door partition continues through the coil box 10 and such door partition has hangers 28 and associated rollers 35 located at the top thereof and facing the direction opposite the rollers of the partition. When the partition and door are retracted, the partition'will be removed from the supporting track and coiled about the post 66 while the door partition will remain on the track and be retracted within the coil box 10.
With reference to FIGS. 2 and 7-11, a traveling door is illustrated which provides a passage through the central portion of the coilable partition. Such traveling door includes a pair of enlarged spaced vertical posts 69 and 70 interposed in the coilable partition 11 with the intermediate slats 71 being shortened to provide a doorway or opening 72 in the bottom thereof. The opening 72 is adapted to be closed by a door 73 located between spaced posts- 74 and 75 corresponding in width to the posts 69 and 76. The posts 74 and 75- are connected by a sill 76 and a lintel 77 to provide a frame for the door and such posts are supported by hangers 78 and rollers 79 operable within a track 80 located adjacent to the track 36. The posts 74 and 75 are maintained in predetermined spaced relation by an adjustable connecting link 81 intermediate the hangers 78. The track 80 terminates a predetermined distance from the coil box and the end thereof is closed by a cap 82 in which an adjustable bumper or stop 83 is located to limit the outward movement of the door posts 74 and 75.
When the coiled partition is retracted within the coil box 10 the door 73 is automatically retracted by the partition and when the partition is extended the door is automatically extended therewith. This is accomplished by providing the lower portion of the post 74 with a hook 84, the free end of which extends in the direction of inward travel, and providing the post 69 with a cooperating eye so that as. the partition is extended the hook 84 on the post 74 will engage the eye on the post 69' and carry it outwardly until the bumper 60 contacts the opposite wall and one of the rollers 79 simultaneously contacts the stop 83.
border to retract the door 73 to its initial position within the coil box 10, the outermost hanger 78 has a pin 36 welded or otherwise attached thereto and such pin projects laterally and terminates above the coilable partition. A pin 87 is mounted on the top of the strip '50 in a position to engage the pin 86 when the partition is retracted. During the initial retraction of the partition the hook 84 is withdrawn from the eye 85 and the door remains stationany as the partition is coiled within the box 10.
When the free end of the partition reaches a position substantially adjacent to the traveling door, the pin 86 will engage the pin 87 and retract the traveling door into the coil box. If desired, the frame of the traveling door may have .a buffer 83 encircling the door area so that the door will fit snugly against posts 70 and 71. The hook 84 and the cooperating eye 85 prevent lateral movement of the posts 74 and 75 and such hook and eye in conjunction with the stop '83s prevent longitudinal movement of the traveling door. The traveling door 73 may be provided with a conventional operating latch and lock (not shown) or may be freely swingable.
With reference to FIGS. 12-45, a modified form of the invention is illustrated, in which the free end of the coil able partition is not provided with a door but, instead, the lower portion of the partition is cut away to form a contour-fitting lower edge which conforms to an obstruction such as a grandstand. When the coilable partition is coiled Within the coil box the partition rests on the shoes 21 at the bottom thereof. In order to support the free end of the partition when it is coiled within the box 10, the hangers 28 on the free end of the partition are reversed to face the direction opposite the hanger-s on the coilable partition and the rollers 35 mounted on such hangers engage the opposite side of the track 36. Within the coil box one side of the track is omitted, as previously described, ,to facilitate the coiling of the major portion of the partition and the rollers which face the direction of the omitted portion are free to leave the track inside the coil box. The other portion of the track is spirally arranged so that the free, unsupported end of the partition will remain on the track and be suspended therefrom.
It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.
