Abstract

A segmented closure system for providing a closure strip of variable length capable of allowing the efficient opening and closing of an object to form a barrier such as a temporary door. The segmented closure system generally includes a pair of closure members each including a magnet for removably securing the closure members together. Each closure member includes a fastener for securing the each closure member to an object, such as to a pair of adjoining plastic sheets to form a temporary barrier such as a door. Each closure member may include mating connectors for linking the pair of closure members together end-to-end in a linear or angled orientation. Each closure member may include a pivotable segment connected to its main body by a connector pin. Temporary barriers of variable sizes may be easily constructed by interlinking multiple closure members together on opposite edges of a pair of plastic sheets.

Claims (22)

1 . A temporary barrier, comprising:

a first sheet secured to a first vertical structure;

a second sheet secured to a second vertical structure;

a first closure member extending along a first inner edge of the first sheet; and

a second closure member extending along a second inner edge of the second sheet, wherein the first inner edge faces the second inner edge;

a lower sheet spanning a width of a lower end of each of the first sheet and the second sheet;

a third closure member extending along the lower end of the first sheet, the third closure member being attached perpendicularly to a lower end of the first closure member;

a fourth closure member extending along the lower end of the second sheet, the fourth closure member being attached perpendicularly to a lower end of the second closure member;

a magnetic threshold attached to an upper end of the lower sheet, the magnetic threshold being formed by at least one closure member;

wherein the third closure member and the fourth closure member are each removably attached to the magnetic threshold so as to temporarily secure the first sheet and the second sheet to the lower sheet;

wherein a lower end of the lower sheet is secured to a floor surface; and,

wherein the first closure member is removably attached to the second closure member so as to temporarily secure the first sheet to the second sheet.

2 . The temporary barrier of claim 1 , wherein the first closure member and the second closure member each include one or more magnets.

3 . The temporary barrier of claim 1 , wherein the first closure member and the second closure member are secured together by a zipper.

4 . The temporary barrier of claim 1 , wherein a lower edge of the lower sheet is secured to the floor surface by tape.

5 . The temporary barrier of claim 1 , wherein a lower edge of the lower sheet is removably or fixedly secured to a floor surface.

6 . The temporary barrier of claim 1 , wherein the first vertical structure and the second vertical structure are each comprised of a wall.

7 . The temporary barrier of claim 1 , wherein an upper end of the first sheet and an upper end of the second sheet are each movably secured to a track positioned above the first sheet and the second sheet.

8 . The temporary barrier of claim 1 , wherein the second closure member comprises a first mating connector, wherein the fourth closure member comprises a second mating connector, and wherein the first mating connector is removably engaged with the second mating connector.

9 . The temporary barrier of claim 8 , wherein the magnetic threshold is comprised of a third closure member.

10 . The temporary barrier of claim 8 , wherein the lower end of the lower sheet is secured to a floor surface by tape.

11 . The temporary barrier of claim 8 , wherein the lower end of the lower sheet is secured to a floor surface by one or more fasteners.
