FLooR SEAL FOR RooM DIVIDER PARTITION Filed sept. e, 1962 2 Sheets-Sheet 2 United States Patent O i 3,126,651 FLUR SEAL FR ROQM DIVIDER PARTITION Victor Sussin, Elmhurst, Ill., assigner to Brunswick Corporation, a corporation of Delaware Filed Sept. 6, 1962, Ser. No. 221,751 11 Claims. (Cl. 160-40) This invention relates to an extensible room divider installation, and more particularly to a floor seal assembly for such an installation.

Primary objects of this invention are to provide a new and useful installation of the type described and a door seal therefor.

Various types of extensible room dividers are well known, for example, partitions such as sliding doors, folding panels, traverse drapes and ilexible acoustical curtains such as woven lead materials. Often such curtains are used as room dividers, suitably suspended from the ceiling of the room and operable between extended and retracted positions. It is highly desirable that such curtains electively prevent drafts and the transmission of sound between portions of a room lso divided. In order to adequately accomplish these desirable functions, there should be no openings between the divided portions of the room, but with such curtains it has been particularly difficult to properly seal the area between the lower portion of the curtain and the floor.

An important object of this invention is to provide a new and useful assembly mounted on a floor for providing closure means between a draw curtain and the iloor in a room divider installation.

Another object is to provide a new and useful assembly installed in a iloor `for providing a closure between a curtain and the oor and `generally level =with the iloor when the curtain is retracted and the assembly is closed.

Another object is provision of a new and useful draw curtain floor seal assembly which effectively clamps and seals the juncture of the lower edge of a draw curtain and the floor.

Other objects and advantages of the invention will become readily apparent from the following detailed description taken in connection with the accompanying drawings, in which:

FIGURE l is a vertical sectional View of a preferred embodiment of the invention in the form of a floor seal assembly for a suspended draw Curtain installation, with the floor seal in open position and the curtain received therein;

FIGURE 2 is an enlarged vertical sectional view, similar to FIGURE l, but with the oor seal clamping and sealing the lower edge portion of the curtain;

FIGURE 3 is a vertical sectional view, similar to FIG- URE 2, but with the floor seal in closed position; and

FIGURE 4 is a top View of the door seal assembly in closed position, to the scale of FIGURE l, and with parts broken away for clearer illustration.

While an illustrative embodiment of the invention is shown in the drawings and will be described in detail herein, the invention is susceptible of embodiment in many different forms, and it should be understood that the present disclosure is to be considered an exemplioation of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.

The invention is, in brief, directed to a door seal assembly `for releasably clamping and sealing the lower edge portion of a curtain or the like and providing a generally coplanar oor surface when the curtain is open. A novel operating mechanism is provided for actuating a floor seal member.

3,126,051 Patented Mar. 24, 1964 With reference to the drawings, a draw curtain, illustrated in the form of a `folding acoustical curtain 10` is suitably suspended, as from the ceiling of a room by ceiling :attached track 10a carrying curtain attaching trolleys 10b, for operation across a Hoor F or other surface, between open (retracted) and drawn (extended) positions. As shown in FIGURE 2, a lower edge portionw11 of curtain 10 is clamped and sealed in a floor seal assembly 12 by means of a clamping :shoe 13. FIGURE l shows floor seal 12 in open position so that curtain 10 may be operated therein between open position and closed drawn position. In FIGURE 3, iloor seal 12 is in closed position with curtain 10` withdrawn and shoe 13 and a cover 14 cooperating with flanges 15 of a channel-shaped body portion 16 of the floor seal assembly to define with floor F a generally level and coplanar surface.

Body .116 has an elongated trough 18 extending along the path traversed by curtain lo in movement between open and closed positions, and this trough is defined by opposed side Walls 19 and 2@ interconnected by a bottom Wall V21 countersunk in the iloor, and flanges 15 extending outwardly from the upper edges of side Walls 19` and 20* and receiving suitable fasteners for securing the seal assembly to the floor.

In order to provide a more compact and easily handled Y unit, the oor seal is made in relatively short lengths operatively assembled with ends 21 of adjacent bodies 16 abutting each other and firmly secured together as by straps 22 spanning abutting ends 21 and suitably secured to adjacent bodies as by bolts 2.3, one strap 22, lfor each side wall 19 and 20 and bottom wall 21.

Clamping shoe 13 is mounted on body 16, and more particularly is pivoted to the body in any suitable manner as by a strap hinge 24 bolted to bottom wall 2b1 and to the lower portion of shoe 13. A strong torsion spring y25 (FIG. 4) is suitably mounted on hinge pin 26 of hinge 2dthereby providing resilient means urging shoe 13 to seated position against body lside wall 2t) at the upper face of the body when the seal is closed, or in direct engagement with curtain lower edge portion 11 and clamping and sealing any opening between the curtain and floor to eifectively prevent the passage of drafts and sound around the lower edge of the curtain. As may best be seen in FIG. 2, the curtain is thus tightly held between shoe 13 and wall 20; and more particularly between resilient seal gaskets 27, preferably extruded vinyl material, suitably mounted in wall 20 as by dovetail connections.

With reference to FIG. 3, when oor seal 12 is normally closed, its cover 14 has one edge portion 30 seated against 4a generally horizontal face of a cut-out portion 31 in the upper and inner face of shoe 13 to effectively prevent the shoe from pivoting counterclockwise as viewed in FIG. 3, thus providing an interlock releasably holding the shoe in closed position. The opposite edge 32 of cover 14 is provided with an elongated rounded portion 33 received in a cooperating elongated rounded channel 34 on the upper edge of body side wall 19, thereby mounting the cover for pivotal movement between the closed position as shown in FIGURE 3 and an open position as shown in FIGURE l. Tension springs 35 are suitably secured at one end to an intermediate portion of the inner face of cover 14 and at an opposite end to a portion of hinge pin 26 and provide resilient means urging cover 14 to closed position.

Means is provided for operating Ithe tloor seal assembly between closed and open positions, and herein this means is in the form of an operating shaft 36 extending axially in a direction longitudinal of and within trough 18` and journalled in suitable mounts 37 of body 16. Actuators 38 are axially spaced along and secured to shaft 36 for rotation therewith, and each has a cam portion 39 which engages the inner rface of cover 14; -upon rotation of shaft 316 in one direction (counterclockwise 1in FIGURE 2) to pivot cover 14 to open position against the urging of spring 35. Shank members 40 are pivotally mounted by pivot pins 41 on actuators 38 and extend through openings 42 in shoes 13, with a head 43 of each member dit seated in a cooperating socket on a side of the shoe opposite pivot pin 41. When shaft 36 is rotated counterclockwise, as viewed in FIGURE 2, shank 40 is moved to the lef-t, thus pivoting shoe 13 counterclockwise to open position. Thus, curtain may be moved, through the resultant gap between shoe 13 and wall 2Q, between open and drawn positions. Upon rotation of shaft 36 in an opposite direction (clockwise in FIGURE l), torsion spring 2.5 urges shoe 13 clockwise, and when the shoe is seated against either curtain 10 or wall 20, continued rotation of shaft 36 permits head A43 to move away from the socket in shoe I3, thus providing a lost motion connection and assuring proper seating of' the shoe against either the curtain or wall 20 of the body, as shown in FIGURES' 2 and 3, respectively.

Means ffor operating shaft 36 is provided in the illustrated embodiment by a cable actuating mechanism including a part E-S- secured to shaft 36 yfor rotation therewith and having an arcuate periphery 46 receiving a cable 47 secured at one end ii to part 45 and having an opposite end passing around a pulley 49 and connected with a suitable cable reeling device (not shown). Thus, upon tensioning cable 47, shaft 36 is rotated counterclockwise, as viewed in FIGURE l, to` open the seal, and upon releasing cable `46, shaft 36 rotates clockwise as shoe 13 and cover 14 move toward seated position.
