BACKGROUND

Partition systems are employed to isolate portions of a building or room, by serving as a barrier to dust, noise, light, odors, and other intrusions. In construction zones, partitions are useful for protecting a clean area from a work area, for example, protecting an area where furniture and rugs are temporarily stored from an area where wood floors are being refmished.

Workers at construction sites often use rudimentary techniques for installing partitions. Some simply nail, screw, or staple the curtain or partition material to the floor, ceiling, and abutting walls, resulting in damage to their surfaces. Other workers setting up a barrier employ tape or other adhesives which could result in paint being removed from the wall or the adhesive material being difficult to remove. The tape usually fails to stick, but, if it does stick, as the tape is removed, paint can pull off with the tape, or adhesive is left behind.

United States Patent Nos, 5,924,469 and 7,658,219, incorporated herein by reference, disclose partition mount systems that address these limitations. These systems utilize a plurality of spring-biased pole mounts that secure a curtain or drape material, such as plastic, cloth, and the like, to form a temporary partition. The disclosed system is a "clean" system configured to be installed and removed without damaging or otherwise marking the ceiling, floor or walls in the construction zone. Assembly is easy and fast and can be accomplished by a single individual. In certain applications, however, a sag, or gap, may be present in the curtain along a pole next to a wall, ceiling, door frame, or other abutting surface,

compromising the effectiveness of the installation.

United States Patent No. 7,533,712, the content of which is incorporated herein by reference, discloses a mount system that mitigates or eliminates sag, or gaps, between an installed curtain and an abutting surface such as a wall or ceiling. The system accomplishes this in a manner that avoids permanent damage to the wall or ceiling surface. The system includes a head with an elongated body and a compressible curtain interface. A pole, for example, as described in connection with United States Patent No. 5,924,469 and United States Patent No. 7,658,219, may be configured to urge the head and the curtain to the abutting surface, thereby eliminating a sag, or gap in the curtain.

In certain configurations, a pole supporting the elongated body of the head may be positioned so as to inhibit human movement. In addition, a single, elongated head may not be long enough to eliminate all of the sag in the partition system, and, thus, multiple poles and corresponding elongated heads may be required.

In some situations, it is desired to have a defined entryway location for ingress into / egress from a partitioned area. Contemporary entryway mechanisms for such systems can employ a zipper mechanism, such as a zippered doorway. Such systems require an operator to manually un-zip the doorway to permit entry/exit and to re-zip the doorway to re-seal the entry way after entry/exit.

DETAILED DESCRIPTION OF EMBODIMENTS

Various example embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some example embodiments are shown. The present inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein.

It will be understood that when an element or layer is referred to as being“on,” “connected to” or“coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being“directly on,”“directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numerals refer to like elements throughout. As used herein, the term“and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present inventive concepts.

Spatially relative terms, such as“beneath,”“below,”“lower,”“above,”“upper ” and the like, may be used herein for ease of description to describe one element’s or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as“below” or“beneath” other elements or features would then be oriented“above” the other elements or features. Thus, the example term“below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

FIG. 1 is a perspective view of an embodiment of a zipper pull system 10000, in accordance with aspects of the present inventive concepts. In the embodiment shown in FIG. 1, one or more spring-biased pole mounts 30a, 30b, 30c (see, for example, FIG IB) secure a curtain 100 or drape material, such as plastic, cloth, and the like, to form a temporary partition. In some embodiments, the curtain 100 comprises one or more zippers 200 constructed and arranged to form a doorway region 50. In the embodiment shown in Fig. 1, the curtain 100 comprises a zipper arranged to form a doorway region 50. When the zipper 200 is open, the curtain 100 comprises an opening 70 (see FIG. 3). In some embodiments, the opening 70 is constructed and arranged to allow an operator to pass through. Although the embodiment shown in FIG. 1 comprises one zipper 200, alternative embodiments comprise a different number of zippers.

In some embodiments, the one or more zipper 200 comprises zipper tape. In some embodiments, the zipper tape comprises a left portion and a right portion, each, for example including opposed zipper teeth. In such embodiments, when the zipper is in the open state, a zipper pull 210 of the zipper 200 is coupled to teeth at either the left portion of the zipper tape or the right portion of the zipper tape.

In the embodiment shown in FIG. 1, the zipper pull system 10000 comprises an elongated pull 300 securely coupled to the zipper pull 210 (see FIG. 2), a first pulley 400, and a second pulley 600. In this embodiment, the elongated pull 300 extends in a direction at a first side 101a, for example near a front surface, of the curtain 100 and is securely coupled to the zipper pull 210, which is likewise located at the first side 101a of the curtain 100. In this embodiment, the elongated pull 300 is coupled to a first pulley 400 positioned near the top 201b of the zipper 200. In this embodiment, the elongated pull 300 passes through a first hole 22 (see for example, FIG. 7) in the curtain 100 and extends in a direction along a second side 101b, for example near a rear surface, of the curtain 100 toward and through a second pulley 600 positioned near the bottom 201a of the zipper 200.

In alternative embodiments, the elongated pull 300 passes below the curtain 100 and emerges back at the first side 101a of the curtain 100 at a position at, or near, a bottom 201b of the zipper 200.

In alternative embodiments, the elongated pull 300 passes through a first hole 22 (see for example, FIG. 7) in the curtain 100 and extends in a direction along a second side 101b of the curtain 100 toward a second pulley 600 positioned near the bottom 201a of the zipper 200. In such alternative embodiments, the elongated pull 300 passes through a second hole 24 (see for example, FIG 21) and emerges back at the first side 101a of the curtain 100 at a position at, or near, a bottom 201b of the zipper 200.

In FIG. 1, the first pulley mount 500 secures the first pulley 400 to the curtain 100 at a position at, or near, a top of the zipper 200. In FIG. 1, the second pulley mount 700 secures the second pulley 600 at or near a bottom 201a of the zipper 200. In some embodiments, the user can open the zipper 200 by moving the elongated pull 300 in a first direction relative to the first pulley 400 and the second pulley 600. In some embodiments, the user can close the zipper 200 by moving the elongated pull 300 in a second direction relative to the first pulley 400 and the second pulley 600.

In the embodiment shown in FIG. 1, the zipper pull system 10000 is arranged vertically. In this embodiment, the user can open the zipper 200 by moving the elongated pull 300 in an upward direction 301b. In this embodiment, a user can close the zipper 200 by moving the elongated pull 300 in a downward direction 301a. In alternative embodiments, moving the elongated pull in an upward direction closes the zipper. In alternative embodiments, moving the elongated pull in a downward direction opens the zipper.

In the embodiment, shown in FIG. 1, if the user is on the second side 101b of the curtain 100, the directions corresponding to opening and closing the zipper 200 are reversed. In this embodiment, from the second side 101b of the curtain 100, moving the elongated pull 300 in the upward direction 301b will close the zipper 200.

In alternative embodiments, the zipper pull system 10000 is not arranged vertically. In such embodiments, in order to open/close the zipper, the user may need to move the elongated pull in a direction with both a vertical and/or horizontal component.

In some embodiments, for example in the present illustrative embodiment, the elongated pull 300 comprises a rope. In alternative embodiments, the elongated pull 300 comprises a different elongated material that is constructed and arranged to transfer tension, including, but not limited to, string, wire, cables, ribbon, belt, or any such suitable material. In alternative embodiments, the position and movement of the elongated pull 300, for example in an upward and downward direction 301b, 301a is controlled remotely.

In some embodiments, a zipper pull system 10000 is assembled by first mounting a pole 30a between first and second surfaces, for example between a floor and a ceiling of a building. In some embodiments, a curtain 100 is coupled to the pole 30a, and the pole 30a operates to create vertical tension in the curtain 100 between the floor and the ceiling. Neighboring poles 30c, etc. (see, for example, FIG. 1 A), likewise mounted, operate to create horizontal tension in the curtain. In this manner, the pole system creates vertical and horizontal tension in the curtain, which tension is transferred to similarly tension the zipper 200. At least one of the poles, for example pole 30b in the present example of FIG. 1, is mounted so that the foot 31 (see FIG. 4) of the pole 30b is proximal a lower portion 201a of the zipper 200. In some embodiments, a first pulley mount 500 and a first pulley 400 are mounted to a region of the curtain 100 above an upper portion 201b of the zipper 200. In some embodiments, a second pulley mount 700 and a second pulley 600 are mounted at or near the lower portion 201a of the zipper 200. In some embodiments, an elongated pull 300 is coupled to the first pulley 400, the second pulley 600, and securely coupled to a zipper pull 210. In this manner, the elongated pull 300 is sufficiently tensioned between the first pulley 400 and second pulley 600 so as to form an elongated loop of material that passes along the first, front side 101a and second, rear side 101b of the curtain 100, passing through an upper portion of the curtain 100 at an upper opening at or near the first pulley 400 and passing through a lower portion of the curtain 100 at or near the second pulley 600. In some embodiments the elongated pull 300 passes through the lower portion of the curtain 100 at or near a lower opening in the curtain at or near the second pulley 600. In other embodiments the elongated pull 300 passes through the lower portion of the curtain 100 at or near a lower opening in the zipper 200 at or near the second pulley 600. In some embodiments, manually grasping the elongated pull 300 and pulling the elongated pull 300 in one direction, for example in the upward direction 301b, opens the zipper 200 and manually grasping and pulling the elongated pull 300 in the opposite direction for example in the downward direction 301a closes the zipper 200. Accordingly, an operator can stand at normal height and open and close the zipper 200 no matter the position of the zipper pull 210. In this manner, the elongated pull 300 operates as an extension of the zipper pull 210, eliminating the need for an operator to bend over and reach downward for the zipper pull 210 when it is positioned below the operator’s body, and similarly eliminating the need for an operator to reach upward for the zipper pull 210 when it is positioned above the operator’s body. During the opening and closing process the first pulley mount 400 is sufficiently secured to the curtain 100 to withstand the tension applied to the elongated pull 300 and, accordingly, the pulley 400. Similarly, during this process the second pulley mount 700 is sufficiently secured in position to withstand the tension applied to the elongated pull 300 and, accordingly, the pulley 600.

In the embodiment shown in FIG. 1, the zipper pull system 10000 is coupled to a zipper 200 oriented in a vertical direction, for example positioned between a floor and ceiling of a room or between surfaces of an object. In alternative embodiments, the zipper pull system 10000 is coupled to a zipper oriented in a horizontal direction, for example positioned between walls of a room or between surfaces of an object. In alternative embodiments, the zipper pull system 10000 is coupled to a zipper oriented in a direction with both vertical and horizontal components, for example between walls, floors, or ceilings of a room or between surfaces of an object.
