Patent ID: 8261490

Claim:
A sliding expanding incrementally adjustable barrier for placement between two opposing locations, comprising: a) a first slidable partition comprising a first frame, with the first slidable partition extending in the length and height directions; b) a second slidable partition comprising a second frame, with the second slidable partition extending in the length and height directions; c) wherein a direction between the first and second partitions is a width direction, wherein said first and second partitions are engaged to and spaced apart from each other in said width direction, wherein said frames of said first and second partitions lie parallel to each other and slide parallel to each other; d) an elongate member engaged to the first partition and engaged between the first and second partitions and being disposed in said length direction, with said elongate member having predefined spaced apart locations; and e) a slidable piece on said elongate member and being slidable on said elongate member in said length direction, with said slidable piece having a first portion and a second portion, with said first portion being engagable to said elongate member at said predefined spaced apart locations, with said second portion having a threaded member turnable thereon, with said threaded member having an end confronting the second partition and being turnable to confront the second partition, with said threaded member being turnable to and from said first portion in the length direction and thus being turnable to and from said second partition in the length direction, such that when said threaded member is turned on said second portion to confront the second partition and when said first portion is engaged at one of said predefined locations on the first partition, said threaded member brings pressure to bear upon said second partition and draws the first and second partitions slidingly in opposite directions along said length direction such that ends of the first and second partitions are incrementally drawn apart to incrementally place pressure upon said opposing locations.
