DEVICE FOR FIXATION OF DOORS AND DRAWERS (VERSIONS) Russian patent published in 2009 - IPC E05C19/16 

FIELD: construction.

SUBSTANCE: invention is related to furniture industry and may be used for locking or fixation of doors, leaves, drawers, etc. Device for fixation of doors and drawers consists of magnet and magnetic flux concentrator. Magnet is arranged in the form of radially magnetised disc with hole and is installed with the possibility of rotation on shaft in clearance. Clearance is formed by two concentrators of magnet flux and attracts the plate made of magnet-conducting material. As shaft turns at the angle of 90°, concentrators short-circuit filed of magnet scattering, providing for magnet field reduction in clearance almost down to zero, as a result, plate is not attracted. According to another version of device for fixation of doors and drawers at the turn of 90°, concentrators short-circuit field of magnet scattering, providing reduction of magnetic field in clearance, and at the turn of 180°, field in clearance between concentrators increases intensely, at that its polarity is such that plate of permanent magnet is pushed away from it.

EFFECT: provision of both rigid mechanical fixation of leaves and simplification of their opening due to pushing of device elements, expansion of arsenal of technical means.
