Claims66
A boom curtain section comprising:
- one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges;
- and
- a first zipper element adjacent a portion of the length of each lateral edge, each of the first zipper elements comprising a set of zipper teeth attached to a strip of material, the strip of material being secured to the one or more sheets of flexible material with the set of zipper teeth recessed from its adjacent lateral edge, whereby upon mating engagement of the zipper teeth on the first zipper element adjacent one lateral edge with a corresponding zipper element adjacent a lateral edge of an adjoining curtain section, the boom curtain section and the adjoining curtain section overlap.
A boom curtain section comprising:
- one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges, the upper edge being adapted and configured for connection to a support system, and
- a first zipper element adjacent a portion of the length of each lateral edge and the lower edge, each of the first zipper elements comprising a set of zipper teeth attached to a strip of material, the strip of material being secured to the one or more sheets of flexible material with the set of zipper teeth recessed from its adjacent lateral or lower edge, whereby upon mating engagement of the zipper teeth on the first zipper element with a corresponding zipper element adjacent an edge of an adjoining curtain section, the boom curtain section and the adjoining curtain section overlap.
A boom curtain section comprising:
- one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges, the lower edge being adapted and configured for connection to an anchor or ballast;
- and
- a first zipper element adjacent a portion of the length of each lateral edge and the upper edge, each of the first zipper elements comprising a set of zipper teeth attached to a strip of material, the strip of material being secured to the one or more sheets of flexible material with the set of zipper teeth recessed from its adjacent lateral or upper edge, whereby upon mating engagement of the zipper teeth on the first zipper elements with a corresponding zipper element adjacent an edge of an adjoining curtain section, the boom curtain section and the adjoining curtain section overlap.
A boom curtain comprising two or more upper curtain sections, two or more lower curtain sections, and two or more main curtain sections connected together to form a boom curtain,
- each upper curtain section comprising one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges, the upper edge being adapted and configured for connection to a support system, and a first zipper element secured to the one or more sheets of flexible material adjacent a portion of the length of each lateral edge and the lower edge;
- each main curtain section comprising one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges, and a first zipper element secured to the one or more sheets of flexible material adjacent a portion of the length of each lateral edge and the upper and lower edges;
- and
- each lower curtain section comprising one or more sheets of flexible material that allow the flow of water therethrough, the one or more sheets of flexible material having an upper edge, a lower edge, and opposed lateral edges, the lower edge being adapted and configured for connection to an anchor or ballast, and a first zipper element secured to the one or more sheets of flexible material adjacent a portion of the length of each lateral edge and the upper edge;
- wherein zipper elements adjacent the lower edges of the two or more upper curtain sections are connected to zipper elements adjacent the upper edges of adjoining main curtain sections, zipper elements adjacent the lateral edges of the two or more upper curtain sections are connected to zipper elements adjacent the lateral edges of adjoining upper curtain sections, zipper elements adjacent the lateral edges of the two or more main curtain sections are connected to zipper elements adjacent the lateral edges of adjoining main curtain sections, zipper elements adjacent the lower edges of the two or more main curtain sections are connected to zipper elements adjacent the upper edges of the two or more lower curtain sections, and zipper elements adjacent the lateral edges of the two or more lower curtain sections are connected to zipper elements adjacent the lateral edges of adjoining lower curtain sections.
