SPIRAL ELASTIC SHELL OF MOBILE PART OF HARNESS Russian patent published in 2024 - IPC F16L3/15 H02G11/00 

FIELD: load-bearing devices.

SUBSTANCE: invention relates to load-bearing devices for moving parts of harnesses connecting a fixed part of equipment to a moving one. The technical result consists in increasing the service life of the harness by ensuring uniformity and simultaneous deformation of the coils of the spiral of the harness during its movements. The technical result is achieved by the fact that the shell of the moving part of the harness is an elastic shell into which the harness is inserted, and at the ends of which fastenings to the moving and stationary parts of the equipment are installed. The elastic shell has the shape of a spiral, and its length in a free, unstressed state is between the extreme points of the working stroke of the harness. The work of the spiral during the working stroke is carried out in compression and tension. The rigidity of the spiral elastic shell is greater than the rigidity of the bundle embedded in it and can vary along the length of the shell as a result of changes in the shape of the spiral and its cross section. The cross-sectional profile can be made open, open with a removable part covering the profile groove, or closed. Attachments to equipment at the ends of the spiral elastic shell are made in the form of hinges.

EFFECT: increasing the service life of the harness by ensuring uniformity and simultaneous deformation of the coils of the spiral of the harness during its movements.
