Telescoping Door Swing Clear Hinge Breakout Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescoping door systems in intensive care units lack the ability to create large enough openings for oversized equipment and furniture due to limitations in pivot axes positioning and breakout functionality, which is crucial for emergency egress and equipment movement.
Innovation Solution
The telescoping door system incorporates a swing clear hinge that positions the pivot axes closer to the trailing jamb, allowing for a larger slide opening and breakout opening by enabling the sidelite and slide panels to pivot out of the header, creating a larger clear opening without interfering with each other's motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pivot axes are positioned farther from the trailing jamb in conventional telescoping door systems, then the door structure is simpler and easier to manufacture, but the slide opening and breakout opening sizes are reduced, limiting equipment passage capability
Solution Approach 1:
The patent implements a nested hinge system where a first hinge is integrated within a second hinge structure. The first hinge allows the sidelite panel to pivot relative to the trailing jamb, while the second hinge enables the slide panel to pivot relative to the sidelite panel. This nested configuration achieves the required large breakout opening without requiring the pivot axes to be positioned at the extreme edges, thus maintaining structural feasibility while maximizing the clear opening area.
2Area of stationary object
If the pivot axes are repositioned closer to the trailing jamb to increase opening size, then the breakout opening area increases for better equipment passage, but the door panels may interfere with each other's motion during sliding and pivoting
Solution Approach 1:
The patent divides the pivoting function into two separate hinge mechanisms: a first hinge connecting the sidelite panel to the trailing jamb, and a second hinge connecting the slide panel to the sidelite panel. This segmentation allows each hinge to operate independently with its own pivot axis positioned optimally, enabling the slide panel and sidelite panel to pivot without interfering with each other's motion paths, thus achieving a large breakout opening while maintaining smooth operation.
Solution Approach 2:
The patent introduces a hierarchical pivoting mechanism where the slide panel pivots relative to the sidelite panel (first dimension of motion), and the sidelite panel simultaneously pivots relative to the trailing jamb (second dimension of motion). This multi-dimensional pivoting arrangement allows the door system to achieve a large breakout opening area while the segmented hinge structure prevents motion interference between panels during operation.

AI summary
A door system includes a track spanning a doorway defined by a trailing jamb and an opposing lead jamb, a sidelite panel coupled to the trailing jamb by a swing clear hinge, and first and second slide panels moveable within the track. The trailing jamb includes a jamb face facing in a first direction. The swing clear hinge includes a fixed portion engaged with a revolving portion. The fixed portion is offset from the jamb face in a second direction and secured by a jamb attachment member to the jamb face. The first and second slide panels have an open configuration in the track with the revolving portion offset from the jamb face in the second direction. The panels are configured to pivot out of the track into a breakout configuration. The sidelite panel is offset from the jamb face in the second direction in the breakout configuration.
