Door Installation Mechanism With Segmented Pivot Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for installing doors with rotary and translational motion are laborious to install on wooden doors, requiring drilling through the entire height of the door and are complex to adjust, especially when positioning the second rotation axis from the jamb.
Innovation Solution
A mechanism featuring a tubular pivot with a rigid connection device that allows for non-welded assembly, adjustable to fit different door heights, and means for setting the distance between rotation axes, enabling easier installation and adjustment without the need for through-holes in the door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pivot defining the third rotation axis is installed to pass through the leaf for its entire height, then the mechanism ensures proper rotary and translational motion, but the installation becomes laborious requiring drilling through the entire height of the door
Solution Approach 1:
The mechanism is divided into separate components: the pivot elements are segmented into upper and lower portions that are installed independently at the top and bottom of the door, eliminating the need for a single through-hole. The connection between segments is achieved through the arm structure that bridges the gap, allowing installation without drilling through the entire door height.
Solution Approach 2:
The installation approach transitions from a vertical through-hole approach to a horizontal assembly approach. Instead of installing the pivot vertically through the door, the mechanism assembles horizontally by attaching arm components to the door face, then connecting these components through the door thickness without requiring through-holes.
2Adaptability or versatility
If means for setting the distance of the second rotation axis from the jamb are included, then the mechanism is functional and adaptable, but the assembly becomes complex and difficult to adjust
Solution Approach 1:
The mechanism incorporates adjustable elements that allow the distance between the second rotation axis and the jamb to be modified after installation. This dynamic adjustment capability enables adaptability to different door configurations without requiring complex pre-assembly procedures, as the adjustment can be made in situ during installation.
Solution Approach 2:
The arm components are pre-configured with connection features that facilitate straightforward assembly. The preliminary preparation of these components includes integrated mounting features that simplify the installation process, reducing the need for complex adjustment mechanisms while maintaining position flexibility.

AI summary
A mechanism for installing a door or other similar closure device with rotary and translational motion, of the type comprising the following elements to be associated with a leaf - first pivoting means, which form a first vertical axis (11) for the pivoting of the leaf (12), in a central region thereof, to means for translational motion arranged so as to slide in a corresponding guide (13) associated with the upper stringer (14) of the frame (15) of the door; - second pivoting means, whose axis is parallel with respect to the axis of the first pivoting means, for the articulation of two arms (16, 17), a first upper arm (16) and a second lower arm (17), which are both pivoted by means of a first end (21, 22) thereof to the frame (15) of the door or window proximate to a jamb (18) so as to form a second rotation axis (20), - third pivoting means, which are formed by the second ends (23, 24) of the arms (16, 17), which are hinged to the leaf (12) so as to form a third rotation axis (26) that passes through the leaf (12) parallel to the first and second axes and in an intermediate position between the two first and second axes when the leaf is in the closed configuration. The second pivoting means comprise a pivot (27) arranged in a compartment (28) formed within the jamb (18), the pivot (27) joining the first ends (21, 22) of the arms (16, 17) and thus causing their joint rotation. The mechanism according to the invention facilitates and improves the installation of doors with rotary and translational motion.
