Elevator Door Coupler With Adjustable Landing-Door Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require multiple different elevator door coupler systems to accommodate various landing door types, leading to increased production costs and time due to the need for custom designs.
Innovation Solution
An elevator door coupler system with an adjustable coupling assembly mounted on a door hanger featuring elongate openings, allowing the coupling assembly to be positioned at multiple points, enabling compatibility with diverse landing door systems without enlarging the hanger or compromising strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different elevator door coupler systems are manufactured to accommodate various landing door types, then compatibility with different landing door systems is improved, but production cost and time increase
Solution Approach 1:
The door hanger is designed with an elongate opening that allows a single coupler system to accommodate multiple different landing door types by adjusting the position of the coupling assembly along the opening, eliminating the need to manufacture multiple specialized coupler systems for different door configurations
Solution Approach 2:
The coupling assembly can be positioned at different locations along the elongate opening of the door hanger to adapt to various landing door roller placements, providing dynamic adjustability rather than requiring multiple fixed designs
2Adaptability or versatility
If the door hanger is enlarged to accommodate adjustable coupling assembly positions, then versatility is improved, but the structural strength and area increase
Solution Approach 1:
Instead of increasing the overall size of the door hanger, the invention utilizes the linear dimension of the elongate opening to provide adjustment range, effectively using one dimension (length of opening) to solve the versatility problem without expanding the door hanger's footprint in other dimensions
3Ease of operation
If material is removed from coupling assembly components to create mounting openings, then ease of assembly is improved, but structural strength decreases
Solution Approach 1:
The mounting function is separated from the structural components by using the elongate opening in the door hanger rather than creating openings in the coupling assembly components themselves, preserving the integrity and strength of the coupling assembly while still enabling easy mounting

AI summary
An elevator door coupler system (1) includes a door hanger (12), for connection to an elevator car door (2) and at least one roller (14a, 14b), mounted to the door hanger (12). The door hanger (12) comprises a first elongate opening (54a, 54b, 60a, 60b, 62a, 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b) for fixedly mounting a coupling assembly (16) arranged to engage a landing door so as to actuate movement of the landing door together with movement of the elevator car door (2), such that a position of the coupling assembly (16) relative to the door hanger (12) is adjustable by mounting the coupling assembly (16) at a different position within the first elongate opening (54a, 54b, 60a, 60b, 62a, 62b, 64a, 64b, 66a, 66b, 68a, 68b, 70a, 70b).
