Sectional door particularly for garage

Abstract

The sectional door (1) for the control of the access opening to a compartment, particularly to a garage compartment, comprises: - a fixed portion including two pairs of vertical guides (5, 6) suitable for extending in a direction substantially parallel to a respective shoulder of the access opening to a compartment; and a movable portion including: a leaf comprising a lower panel (7) and an upper surrounding panel (8), substantially rectangular in shape, extending over the entire width of the leaf and having the lateral sides thereof in sliding engagement along a respective side guide (5, 6); a pair of side support arms (11) each having one end thereof articulated in correspondence to the top of a respective pair of vertical guides (5, 6) and the other end thereof pivoted in correspondence to an intermediate zone (8c) of a respective lateral side of the upper panel (8); and articulated and slidable connection means (12) between the lower panel (7) and the upper panel (8), including a pair of lateral sliding guides (10) provided in correspondence to the lateral sides of the upper panel (8), and a pair of connection levers (13), each having one end (15) thereof in sliding engagement with a respective lateral sliding guide (10) of the upper panel (8) and a second end (14) thereof articulated at the top to the lower panel (7), whereby the lower panel (7) and upper panel (8) are movable between a completely closed position of the access opening, in which they are arranged in a substantially aligned sequence, one on top of the other, along the pairs of vertical guides (5, 6), and a completely open position, in which the upper panel (8) is overhangingly moved to project in the compartment starting from a zone in correspondence to the top of the pairs of vertical guides (5, 6), supported by the pair of side support arms (11) and the lower panel (7) is moved together with, and against the upper panel (8).

Description

technical field [0001] The invention relates to a sliding door particularly suitable for garages. Background technique [0002] Sliding doors are known having a single leaf mounted to slide within a pair of identical sliding guides laterally delimiting access to one compartment (garage) to be closed by said door. The slide guides have a substantially inverted L-shaped configuration and each have a substantially vertical lower section fixed behind the access opening, generally fastened to the ceiling or along the side walls of the compartment, substantially horizontal or inclined relative to the horizontal The upper section and the curved connecting section between the lower section and the upper section. The upper section of each guide extends towards the interior of the compartment by a section whose length is substantially the same as the height of the door. [0003] The leaf of a sliding door usually consists of a plurality of substantially rectangular panels, each of a...

AI Technical Summary

Problems solved by technology

However, this characteristic of sliding doors is also accompanied by many disadvantages

where each upper section of the sliding guide for the sliding door has to be fastened to the ceiling or laterally to the cubicle wall by means of a bulky and ugly supporting structure, which in particular requires considerable installation and assembly time

Moreover, once the sliding door is opened, its leaf is arranged along a large portion of the ceiling of a compartment, usually a garage or warehouse, which reduces the usable space in said compartment
