Fixing device for a multifunctional tool with an extended handle for use by an astronaut in zero gravity

摘要

FIELD: astronautics.SUBSTANCE: invention relates to space equipment, in particular to means of the object environment elements fixing, especially tools under conditions of weightlessness. Extended handle of the multifunctional tool for use under conditions of weightlessness is made with a longitudinal through groove. In the groove a fixing unit is installed, stiff in the longitudinal and transverse directions, consisting of two identical in size rectangular metal frames, each of which in cross section has the shape of the U-profile. Metal frames are fixedly connected to each other to form a cross-section in the joint in the shape of an I-beam. In one of the frames two lateral planes, through grooves are made with the trough-shaped springs installed in them perpendicular to the longitudinal axis of the handle, which ends are clamped between the joined frames. Internal size, i.e. the height k of this frame is defined by thetool handle widthand height c of the window for the safety halyard carbine hook attachment, taking into account the following relationships: k=+c, U-profile flange width h and the groove width b in the tool handle are: h0.5 b; ƒ=0.5 b, where ƒ – thickness of the frame.EFFECT: technical result of the invention is provision of the safety halyard carbine to the tool attachment with the possibility of moving the carbine by the groove along and / or across the handle under conditions of weightlessness by the cosmonaut, including those dressed in a spacesuit under excessive pressure.1 cl, 13 dwg
