摘要:
A lifting column comprising two or more telescopically arranged column elements, where each column element comprises at least two column sub-elements arranged symmetrically on either side of a first vertical plane, one set of sub-column elements closer to the plane than the other set of sub-elements, where the outer sub-elements are slidingly connected to adjacent inner sub-elements by means of guiding sledges, and further where each column sub-element comprises at least two pulley wheels, one upper and one lower, and further where one first continuous flexible member runs from an upper pulley wheel of a first sub-element to a lower pulley wheel on an adjacent sub-element, so that the first flexible member runs on the upper or lower pulley wheels of the innermost sub-elements on either side of the vertical plane, and that the flexible member is shortened or lengthened by rolling at least one end of the flexible member around a drive wheel on a rotatable axle of an actuating motor. The invention also relates to a patient support table, comprising a patient support surface, a lifting column and a foundation structure for fastening said patient support table to a floor surface.
摘要:
A manipulating system, for manipulating two telescopic columns into desired positions in particular for use in an X-ray apparatus is disclosed, wherein the system comprises: one or more rails arranged in parallel in a first direction X and fastened to a ceiling; a carriage comprising an upper and a lower section, where said upper section comprises means for travelling along the rails in the X direction and the lower section is rotatable about an axis perpendicular to a horizontal X-Y plane by means of a rotation device arranged between the upper and lower section; —two sliding rails arranged in parallel with a mutual distance between the rails, provided in a lower face of the lower section, where the sliding rails overlap each other in the direction of the longitudinal extent of the sliding rails; —two telescopic columns extendable in a Z direction perpendicular to the X-Y plane, where each column is slidably fastened to separate. sliding rails in the lower section, and where the columns may slide past each other on the sliding rails; —connection means arranged in the free ends of the telescopic columns, where said connection means may be used in order to mount X-ray equipment, detectors, extension arms, vision systems and the like.
