DEVICE 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. Device has rigid guide in the form of rectilinear rod of constant round cross-section. Diameter of this guide is smaller than diameter of hole in washers and nuts, which are supposed to be stored on this device, and length of this guide allows placing more than five named nuts and washers. Guide is located horizontally, guide is composite. It consists of two parts, at that one part of the guide is rigidly fixed on the post, which is fixed on the base. Second part of the guide can move along its axis, besides, this second part of the guide is pressed to the first part of the guide by the compression spring. Parts of the guide are aligned, their ends in the contact area of two parts of the guide are made converging when approaching these ends. At that, the convergent part of these zones of the guide parts is, for example, truncated cone, or part of the 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. At that, the end part of this second part of the guide passes through the hole in the second post, which is rigidly attached to the base, wherein the contact zone of the end sections of the guide parts are located approximately at equal distance from the posts. Compression spring is located outside the space between the posts. Outside the space between the posts on the guide the thrust part is fixed, in which the compression spring rests. With its other end the compression spring rests against the part rigidly connected with the second post, and on this thrust part there fixed is a part in the form of a handle, by displacing it along the guide it is possible to squeeze the compression spring and to form a gap between ends of the guide parts in their contact zone.

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