MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641063795 A) filed by Aaroha Engineers Private Limited, Valanchery, Kerala, on May 20, for 'modular stackable lift shaft structure with internal connector insert and hidden fastening arrangement.'
Inventor(s) include Arun M; and C M Muraleedharan.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A modular lift shaft structure comprises stackable ring structures and vertical posts forming a lift shaft assembly. Each ring structure includes ring socket members receiving tongue insert connectors positioned within hollow interiors of the vertical posts. Fastening bolts pass through bolt openings in the vertical posts and engage nuts associated with the tongue insert connectors. Guide rails are mounted using the same fastening bolts, thereby simultaneously securing the guide rails and structurally joining adjacent modular components. Tightening of the fastening bolts clamps the tongue insert connectors against inner surfaces of the vertical posts, generating frictional forces over a substantial contact area that contribute to structural load transfer. The tongue insert connectors extend across adjoining vertical posts to provide structural continuity and direct transfer of vertical loads. The fastening arrangement is substantially concealed from the exterior of the shaft structure, such that substantially no structural bolts or screws are visible from outside the installed shaft. The modular arrangement enables stacking of multiple ring and post assemblies to achieve varying shaft heights while providing self-alignment, simplified transportation, faster erection, and improved aesthetic appearance."
