HOLDER FOR STORAGE OF 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 holder has rigidly fixed with base rigid guide in form of rectilinear rod of 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 holder. And the length of this guide makes it possible to place more than five named nuts and washers on the guide. Guide is arranged horizontally, guide consists of two parts. One part of the guide is rigidly fixed on the post, which is fixedly fixed on the base, the second part of the guide can move along its axis. At that this second part of the guide with its end part is pressed to the end part of the first part of the guide by the compression spring. At that parts of the guide are aligned, their ends in the area of contact of two parts of the guide are made converging when approaching these ends. Convergent part of these parts of the guide represents, for example, truncated cone, or part of sphere surface, or other surface. At the same time that part of the guide, which is pressed by the compression spring, moves along its axis. End part of this second part of the guide passes through the hole in the second post, which is rigidly fixed to the base. On this second part of the guide, between the contact zone and the second post, a thrust part in the form of a large-diameter washer is rigidly fixed on the guide. Compression spring is located between this thrust part and second post. This part of the guide is located inside the compression spring. Compression spring by its one end acts on the second post, and by its other end on this thrust part, fixed on this second part of the guide.

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