Modular Support-Based Revolving Shelf System

Abstract

A modular support-based revolving shelf system comprising a lower base and an upper base, at least one vertical support assembly composed of support tubes interconnected via angled extensions with articulated elbows, and one or more hollow, cuboidal shelf modules rotatably mounted onto the support structure via integrally affixed bearing rings. The bases include pressure-adjustable components for vertical stabilization between floor and ceiling. The system is modular, scalable, and configurable to suit diverse architectural constraints, including sloped ceilings and irregular wall geometries. Modules incorporate access openings and optional reinforcement structures, enabling durable and adaptive spatial organization. The invention is applicable in residential, commercial, or workshop environments.

1 . A modular shelving unit comprising:
 a lower base and an upper base;   at least one vertical support rod assembly comprising a plurality of interconnected support tubes;   a plurality of modular shelves mounted onto the support tubes by means of integrally affixed bearing rings;   wherein the support tubes are joined by angled connectors configured to allow spatial adjustment;   wherein the modular shelves are rotatable about a vertical axis defined by the support tubes; and   wherein the shelving unit is stabilized by pressure-adjustable base components.   
     
     
         2 . The shelving unit of  claim 1 , wherein the lower and upper bases each comprise a pressure plate, an adjustable screw, and a transverse locking pin. 
     
     
         3 . The shelving unit of  claim 1 , wherein the angled connectors each comprise a proximal elbow and a distal elbow arranged to define substantially parallel pivot axes. 
     
     
         4 . The shelving unit of  claim 1 , wherein each modular shelf is formed as a hollow cuboid having at least one lateral access opening. 
     
     
         5 . The shelving unit of  claim 4 , wherein the modular shelf further comprises access openings formed respectively in the top and bottom surfaces, the vertical axes of said openings being laterally offset relative to one another and each having a diameter of at least 80 millimeters (approximately 3.15 inches). 
     
     
         6 . The shelving unit of  claim 1 , wherein the bearing rings are affixed adjacent to both the top and bottom surfaces of each modular shelf, enabling 360-degree rotation about the support tubes. 
     
     
         7 . The shelving unit of  claim 1 , wherein each modular shelf includes an internal arch structure integrated with its top surface for reinforcement. 
     
     
         8 . The shelving unit of  claim 1 , wherein the support tubes, angled connectors, and elbows have diameters between 30 millimeters (1.18 inches) and 600 millimeters (23.62 inches). 
     
     
         9 . The shelving unit of  claim 3 , wherein each elbow has a visible length between 50 millimeters (1.97 inches) and 200 millimeters (7.87 inches). 
     
     
         10 . The shelving unit of  claim 1 , wherein each angled connector has a length between 30 centimeters (11.81 inches) and 300 centimeters (118.11 inches). 
     
     
         11 . The shelving unit of  claim 1 , wherein the floor of at least one modular shelf is raised above the bottom edge of its side walls and reinforced with an underlying plate. 
     
     
         12 . The shelving unit of  claim 11 , wherein the bearing ring thickness matches the thickness of said reinforcing plate. 
     
     
         13 . The shelving unit of  claim 1 , wherein the modular shelves are made of plywood, laminated board, or a similar composite material. 
     
     
         14 . The shelving unit of  claim 1 , wherein at least one modular shelf comprises side walls formed by a plurality of parallel, non-uniform slats interconnected by threaded fastening elements. 
     
     
         15 . The shelving unit of  claim 1 , wherein each modular shelf is shaped as a cube, cuboid, or polygonal prism, and has a height ranging from 10 centimeters (3.94 inches) to 100 centimeters (39.37 inches). 
     
     
         16 . The shelving unit of  claim 1 , wherein at least one modular shelf comprises a skeletal cubical frame constructed of interconnected metal rods, said frame including diagonal struts or braces for reinforcement and incorporating internal grid or shelf structures formed from intersecting rods. 
     
     
         17 . The shelving unit of  claim 1 , wherein the upper base includes an axial mounting hole designed to receive a stabilizing pin previously secured to a ceiling surface, thereby preventing unintended displacement of the upper base during assembly of the unit.
