Tilting table X-ray apparatus

Claim 1

A remote-control tilting table x-ray apparatus which comprises: (a) a stand including two verticle blocks of substantially equal height which extend parallel to one another; (b) a frame movably mounted on said stand, said frame including two pairs of horizontal trunnions having axes which coincide with first and second tilt axes of said frame, said vertical blocks having upper edges with two pairs of retainer housings formed therein, said retainer housings comprising means for accommodating respective trunnions, said frame further comprising three-position sliding locking rods for selectively locking said trunnion pairs within respective pairs of retainer housings, said frame further comprising means for simultaneously actuating said locking rods; (c) a patient-supporting table carried by said frame; (d) an x-ray examining assembly comprising an x-ray source and a support therefor disposed above said table; (e) a film-holder selector disposed below said table; (f) first and second tilt axes for said frame, said first and second tilt axes being disposed parallel to and along each side of a transverse axis of symmetry of said frame; (g) means for tilting said frame with respect to said stand in either direction about either of said tilt axes; (h) a carriage for supporting said x-ray source and support, said carriage being movably mounted along a guide member which extends longitudinally and outwardly of said frame; (i) ancillary imaging means being associated with said film-holder selector, said ancillary imaging means being connected to said frame and projecting below said film-holder projector and away from said x-ray source; (j) means for guiding said film-holder selector and said ancillary imaging means longitudinally with respect to said frame, said ancillary imaging means being slidably mounted on said guiding means such that said ancillary imaging means can be displaced along the entire length of said table; and (k) an eccentrically rotatable actuating disk disposed between two prongs of a fork which is fixed to and which extends transversely from each of said locking rods, wherein said means for simultaneously actuating said locking rods ensures identical movement of said locking rods among their three positions for identical movement of said actuating disks.
