Sliding Door Pivot With Selective Retention For Flexible Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure systems for sliding glass panels often restrict the movement of doors, forcing customers to exit from one end or side, which is inconvenient and less safe, especially in business and restaurant terraces.
Innovation Solution
A closure device with a lower rail and pivot system that allows both panels and doors to slide, featuring a selective retention element and guide elements enabling the sliding door to rotate while retaining only the desired sliding door, while panels can pass freely, and an intermediate separation element for panel management during retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is fixed at one end of the rails and cannot slide, then the door can be easily retained and the structure is simple, but customers can only exit from one end which reduces safety and convenience
Solution Approach 1:
The door is transformed from a static fixed position to a dynamic sliding position. The door can now slide along the entire length of the rails while still being retained at desired positions through the selective retention element, providing flexibility for exit points while maintaining structural simplicity.
Solution Approach 2:
A selective retention element is introduced as an intermediary mechanism between the door and the rails. This element can selectively retain the door at any position along the rails, enabling multiple exit points without requiring complex fixed structures at each end.
2Adaptability or versatility
If panels are evenly distributed along the lower rail, then the upper rail only needs to serve as a guide, but the door cannot slide along the section and must be relegated to one end
Solution Approach 1:
The selective retention element provides localized retention capability at specific positions along the rail. This allows the door to be retained at certain positions while panels can freely pass through other positions, creating different functional zones along the same rail structure.
Solution Approach 2:
The retention function is segmented into discrete selectable positions along the rail. The retention element can engage at different locations, allowing the door to be held at various positions while maintaining continuous passage capability for panels through the guide structure.
3Adaptability or versatility
If a selective retention element is added to allow door sliding, then exit flexibility is improved, but the device complexity increases
Solution Approach 1:
The retention mechanism is merged with the pivot structure. The selective retention element is integrated into the lower pivot assembly, combining the rotation function with the retention function in a single integrated component, thereby reducing overall system complexity.
Solution Approach 2:
The lower pivot structure serves multiple functions: it guides the door movement, enables rotation, and provides selective retention capability. This multi-functional design eliminates the need for separate retention mechanisms, reducing device complexity while maintaining versatility.

AI summary
The invention relates to a closure device (100) characterized in that it comprises a lower rail (12), a lower pivot (1) fastened to the lower rail (12), a fixed door (58) and a sliding door (52). The lower pivot (1) comprises a selective retention element (104) and a guide element (103) that comprises a lower longitudinal passage slot (105) with a width and lower rotation space (106) with a circular shape through which the lower longitudinal passage slot (105) passes, the lower rotation space (106) having a diameter. The sliding door (52) comprises a lower fitting (2) with a lower protrusion (204). The selective retention element (104) comprises a surface (107) and an open cavity (108), accessible in a sliding direction (X), said cavity (108) comprising retention means (109) suitable for retaining the lower protrusion (204) when it is located in said cavity (108). The cavity (108) has a size equal to or smaller than the width of the longitudinal passage slot (105).
