Abstract: Conventional UPVC windows have casements which are pivotable and movable in a limited manner relative to the frame. It is desirable to be to move all the casements such that substantially the entire the frame is opened.

Abstract: An enclosure system includes a plurality of elongated panels consecutively connected to one another. The plurality of elongated panels includes a plurality of independent panels and a panel-door. The enclosure system also includes an upper track constructed and arranged to receive an upper portion of the plurality of elongated panels and a lower track constructed and arranged to receive a lower portion of the plurality of elongated panels. The lower track includes two polytetrafluoroethylene (PTFE) strips constructed and arranged as a transport system for facilitating movement of the plurality of elongated panels along the upper track and the lower track by achieving a very low coefficient of friction enabling heavy weights to be moved with little effort. Substantially all weight of the plurality of elongated panels is supported evenly across a length of the lower track on the two PTFE strips.

Abstract: An enclosure system includes a set of independent panels (1 and 2) which slide longitudinally along an upper guide rail (11) and a lower guide rail (12), in which the weight of each panel rests uniformly and longitudinally along the length of the lower rail (12). The upper rail (11) has a rectangular cross-section and an opening (25) in the lower part thereof. The lower rail (12) is rectangular and the upper part thereof is partially open (24) and delimited by two equidistant sides provided with notches (20) in which Teflon strips (4) are engaged, the panels (2) moving on the strips. Each of the panels (1 and 2) includes a tempered glass pane (10). The upper part of the rotation shaft includes a T-guide screw (5), a rotation guide (6) and a cylindrical part (7) and the lower part thereof includes a screw (16) and a lower guide (15).
