Elevator Guide Rail Mounting Bracket for Door-Aligned Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face challenges in the simple and safe installation of guide rails, which are often complicated and require precise alignment with shaft doors, leading to potential safety hazards and inefficient space utilization.
Innovation Solution
A mounting bracket system with a U-shaped structure, comprising a crossbeam fixed to the floor and side supports, allows for secure attachment of guide rails, ensuring alignment with shaft doors and optimizing space utilization by keeping the crossbeam within the floor, with adjustable fastening points for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting bracket is attached to the shaft wall with mounting openings, then the guide rail can be securely fixed, but the installation process becomes complex and time-consuming
Solution Approach 1:
The mounting bracket is divided into a crossbeam portion and side support portions, with the crossbeam portion having multiple mounting openings for simplified attachment to the shaft wall, while the side support portions provide secure guide rail fixation. This segmentation allows different parts of the bracket to serve specialized functions that reduce overall installation complexity.
2Manufacturing precision
If the mounting bracket extends into the shaft space, then the guide rail can be properly positioned, but the space utilization of the elevator shaft is reduced
Solution Approach 1:
The mounting bracket utilizes the horizontal dimension by extending the crossbeam portion along the shaft wall, rather than projecting vertically into the shaft space. This dimensional approach allows the guide rails to be properly positioned and aligned while minimizing encroachment into the valuable vertical shaft space needed for elevator car movement.
3Measurement precision
If the mounting bracket is installed for each floor, then the guide rail alignment with shaft doors is precise, but the installation time and cost increase
Solution Approach 1:
The mounting bracket design with its crossbeam portion and multiple mounting openings creates a universal attachment mechanism that can be standardized across multiple floors. This universality allows for repeated use of the same bracket configuration, reducing installation time and cost while maintaining precise alignment capabilities through the consistent mounting opening arrangement.

AI summary
A mounting bracket (2) for mounting to a hoistway door opening (6) of an elevator system (1) comprises a transverse support (7) and two lateral supports (8, 9) extending away from the transverse support. The transverse support (7) has two storey fixation portions (15) that can be fixed to a horizontal surface of the storey floor (11). Each of the lateral supports (8, 9) has a rail fastening portion (14) that extends parallel to the first direction and has at least one mounting opening (18) for fastening a guide rail (3) for guiding an elevator car (5).
