ADJUSTABLE FLEXIBLE HANGER Russian patent published in 1996 - IPC

FIELD: thermal engineering. SUBSTANCE: adjustable flexible hanger has flexible block incorporating upper and lower supporting plates 1,2 and spring 3 placed between them which are loosely fastened for locking through their height primarily by means of threaded joint on rods attached to fastening plate located under supporting plates 1,2, rocker arm 8 hinged on one end with thrust rod 12 whose other end is secured to fastening plate and engaging with its second end flexible block; thrust rod is inclined and hinged to fastening plate; rocker arm 8 is engageable with flexible block through hinged rod 16 passed through supporting plates 1,2 and loosely mounted on lower of them. Hanger is provided, in addition, with suspension rod 21 hinged to rocker arm 3 and ceiling girders of framework 26; device to be suspended is hinged to thrust rod 12 under suspension rod 21. Device to be suspended may be attached to thrust rod 12 through control rod hinged to device being suspended and to rod 12. Hinges are cylindrical and all their axes are relatively parallel. Device being suspended may be attached to thrust rod 12 through additional hinge-joint member whose hinge axis is perpendicular to axes of other hinges; control rod may be provided at lower end with intermediate hinge-joint member whose hinge axis is perpendicular to axes of other hinge joints; rocker arm 8 and thrust rod 12 are mounted for changing points of attachment of suspension rod 21 and device being suspended along them, respectively. EFFECT: improved design. 6 cl, 5 dwg
