SIX-ELEMENT LOCK CONNECTION AND MODULAR ELEMENT BASED ON ITS APPLICATION FOR CREATION OF SPATIAL CONSTRUCTIONS Russian patent published in 2013 - IPC A47B96/20 

FIELD: personal use articles.

SUBSTANCE: invention relates to means of creation of spatial rod frames for different purposes (shelf stands, scaffolding, assembled furniture, sports equipment, etc.). The six-element lock connection provides the node connection of up to 6 rods directed in three mutually perpendicular directions. Each of the 6 elements of the lock is a three-dimensional piece, having a shape of rectangular stepped pyramid, all 6 elements together during the assembly form the body of the cubic form. For a rigid connection of the elements of the lock between each other the pinned or screwed connection, self-linking with fixating or adhesive connection is used. The modular element consists of a rod of square or round section, on which ends there are elements of the lock connection rigidly connected to it. The rod may have holes and slots for attaching the additional ties and panels. If in the node of spatial frame the connection of less than six modules (on the side surface or in the corner) is required, the missing modules are replaced by individual elements of the lock connection.

EFFECT: set of similar parts enables to provide quick and easy assembly of spatial rod frames.
