Hybrid Marine Stop Glaze Frame Corner Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marine glazing systems lack structural rigidity, making them unsuitable for applications requiring corner stiffness, such as pivot glass doors and folding doors, due to their narrower frame profile and reliance on fasteners for support.
Innovation Solution
Combining marine type glazing vertical frame members with stop glaze horizontal frame members, utilizing a lug that engages the inward facing exterior surface of the vertical marine glaze frame member and secures into the hollow interior portion of the horizontal stop glaze frame member, creating a rigid corner joint and allowing for a narrower vertical frame profile while maintaining structural integrity.

Engineering Contradiction Analysis
1Length of stationary object
If marine glazing systems are used with a narrower frame profile, then the frame width is reduced, but the structural rigidity and corner stiffness are compromised
Solution Approach 1:
The patent combines marine glazing vertical frame members with stop glazing horizontal frame members to create a hybrid frame system. This merging allows the vertical members to provide narrow profile while the horizontal stop glazing members with their extruded lugs provide the necessary structural rigidity and corner stiffness through efficient force transfer.
Solution Approach 2:
The frame system uses composite construction by integrating different frame member types (marine and stop glazing) with complementary structural properties. The marine glazing provides a narrow profile and glass support, while the stop glazing members provide rigidity through their extruded lug design, creating a composite frame system that achieves both narrow width and structural strength.
2Device complexity
If marine glazing systems rely on fasteners engaged into screw bosses, then the frame construction is simplified, but the corner stiffness and structural integrity are insufficient
Solution Approach 1:
The patent introduces extruded lugs as intermediary elements that connect the horizontal stop glazing frame members to the vertical marine glazing frame members. These lugs act as mediators that efficiently transfer forces between frame elements, providing corner stiffness without requiring complex fastener systems engaged into screw bosses.
Solution Approach 2:
The frame system is segmented into distinct functional components: marine glazing vertical members for profile and glass support, and stop glazing horizontal members with extruded lugs for structural rigidity and force transfer. This segmentation allows each component to optimize its specific function while working together to achieve overall structural integrity.
3Strength
If stop glazing systems use made to fit extruded lugs for rigidity, then the structural strength and force transfer are improved, but the frame profile becomes wider
Solution Approach 1:
The patent applies local quality by using stop glazing horizontal members with extruded lugs only where structural rigidity is needed (at the corners and joints), while the vertical members can have a narrower profile. This localized application of structural reinforcement provides corner stiffness without requiring the entire frame profile to be wide.

AI summary
Disclosed is a framed glazed door or wall panel that can be utilized in applications requiring structural rigidity of the panel frame such as pivot doors, hinged doors, or glass folding doors, and a method for assembling the same. The panel includes marine glaze vertical frame members and horizontal stop glaze frame members. The vertical frame members and horizontal frame members can be rigidly joined by corner lugs inserted the body of the horizontal frame members and captively held on the surface of the vertical frame members.
