DOOR HANDLE AND ITS MANUFACTURING METHOD Russian patent published in 2015 - IPC E05B1/00 

FIELD: construction.

SUBSTANCE: door handle consists of two symmetrical halves, each of which includes a wooden handle and two remote posts; with that, each half of the handle is provided with a single flat shaped base having two identical parts as to length and mirror-like as to configuration relative to the transverse symmetry axis of the base. Configuration of handle posts is made so that there can be provided in each half the displacement of the wooden handle from longitudinal symmetry axis of the base to the side above one of the edges of the base at provision of parallelism of the handle axis to the longitudinal symmetry axis of the base. Besides, each post is made in the form of a set of curved flat plates of different sizes, with that, external outlines of curved sections of adjacent plates are located at equal distance. The invention also proposes a manufacturing method of a door handle, which involves manufacture of at least one handle, manufacture of handle supports, manufacture of a connection device of supports to the handle and manufacture of a device for handle fixation on the door. With that, each support is made in the form of a set of curved flat plates of different sizes, with that, external outlines of curved sections of adjacent plates are located at equal distance. Prior to assembly of supports, their flat plates are cut on templates; after that, plates are assembled on a mandrel; nuts of the device for fixation of the supports on the base are laid inside the supports, and supports are fixed on the template by means of rivets. The base is cut on the template by two impacts with upturn.

EFFECT: use of the proposed inventions allows the following: easier manufacture and installation of a handle, as well as improved reliability of its operation by simplifying its design; improved manufacturability and installation of the handle due to unification of easy-to-manufacture original handle components and provision of its safe-to-operate configuration; reduction of prime cost of manufacture of the handle at provision of high reliability and ease of its use.
