Abstract
Sliding doors, e.g., for pieces of furniture, particularly of the kind with two shutters and reduced height, having coplanar closing and opening by overlapping of the shutters. Support and translation of each shutter is provided by a respective clamp placed on the edge of the outer side, the clamp being linked to a pair of little carriages that can slide transversally with respect to the same shutter, because they are supported and guided by a respective carriage, which in turn can slide longitudinally along the edge of an opening, the respective carriage being led by a rail and control tracks, and engaged by a loose roller that constrains the respective carriage into a couple of longitudinal cams or grooves.
Claims18
A sliding door, comprising:
- a cam guide;
- at least one shutter;
- a clamp configured to be fixed to said at least one shutter;
- a pair of first carriages;
- and
- a pair of second carriages, said second carriages being supported and guided by a rail, which includes a profile, wherein the profile extends along a length of an opening which is to be opened and closed by said sliding door, and said second carriages translate along said opening along the profile;
- wherein said clamp is configured to link said at least one shutter to said pair of first carriages,
- each one of said first carriages is translatable longitudinally along a respective one of said second carriages and is translatable relative to the other of said first carriages, and
- said cam guide comprises grooves into each of which a roller of said first carriages respectively engages such that each roller is movable longitudinally and transversely with respect to said rail.
