SLIDING INCLINED IRREGULAR-AT-THE-TOP SASH WITHOUT STEADY TRANSOM

摘要

Novelty: a sliding sash which is irregular (non-rectangular) at the top and applicable to frames of any kind (aluminium wooden or synthetic frames) is disclosed. Constitution: it has two or more leaves (1), a guide at the top side bearing two visible or invisible carriers per leave (1) which carriers have rollers (2) assisting the unidirectional rolling of the leaves with regard to their vertical axis. Each carrier bears double rollers (4) whereon a steel axle or blade (5) is screwed via a nut (6) and placed on the top inclined guide (3) of the sash. Each axle or blade (5) is placed inside the vertical elements of the leave (1), inside shaped bearings (7). Advantages: the application of the invention to inclined surfaces is not limited by the dimension and inclination of the space; unobstructed view is offered.
