DEVICE FOR LOCATING WASHERS AND NUTS Russian patent published in 2019 - IPC B25B29/00 

FIELD: packaging and storage.

SUBSTANCE: use: for storage of washers and nuts. Summary of invention consists in the fact that device has rigidly fixed with base rigid guide in form of rod, for example, constant round cross-section. Diameter of cross-section of this guide is less than diameter of hole in washers and nuts, which are supposed to be stored on this device. Length of said guide makes more than five thicknesses of said washers and nuts. Guide is composed, it consists of two parts. Besides, these parts of the guide are pressed to each other by their end parts. These parts of the guide form a curve close to the circumference. This curve is located in inclined plane so that zone of contact of end zones of guide parts is located in upper part. At that, in this contact zone each part of the guide has a horizontal rectilinear section. Ends in the area of contact of two parts of the guide are made converging when approaching these ends. Converging part of these zones of the guide represents, for example, a truncated cone, or part of the surface of the sphere, or other surface. End areas of contact of parts of the guide are pressed to each other due to elastic forces of the material of the guide itself.

EFFECT: possibility of removing required washer (nut) without removing other washers (nuts).
