Handle for sacks and bags with a rotary lining comprises of two components. Carrying component is longitudinally cut through cylinder (1) on it has drawn over an elastic and slightly soft rotary lining (2) of the same aperture (3). When axial cams (7) and (8) that are on the inner surface of the rotary lining set in axial channels (9) that are incised in radial channel (5) on cylinder (1) then the apertures (3) and (6) are covered. By revolving, the lining (2) to a certain angle, the cam (8) set in channel (11) and then lining covers i.e. closes the aperture (3). By revolving the lining (2) to the other side, covering the aperture (3) is achieved, and cam (7) sets in channel (10). Rotary lining (2) that slides along the circumference of a cylinder (1) is axially held on the endings of cylinder by limiters (12). On the outer surface of rotary lining (2), recesses (4) are set symmetrically on both sides of the aperture (3) in the form of bearings for a thumb for pressing thereof during revolving. |
