Abstract
Abstract An X-ray examining apparatus has a bed for the patient with a sheet which extends substantially over the entire length of the bed and which is moved by holding and driving means transversely to the bed so as to completely more sideways the body of the patient lying upon the bed. Means are provided to hold the patient from the sides. The invention is particularly characterized by rollers extending parallel to opposite sides of the bed and constituting a part of the holding and driving means. The sheet which is of limited length is unrolled from any one of the rollers and is simultaneously wound upon the other roller, possibly with the use of guide rollers. Means are provided for holding the sheet on the surface of the bed upon which the patient lies.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
380 words
An X-ray examining apparatus comprising a patient-carrying plate, a sheet extending the entire length of said plate and movable transversely to said plate, rollers located along the two longitudinal sides of said plate and extending parallel to said plate, means driving said rollers from the side of the patient in the direction of movement of said sheet, means guiding said sheet in the plane of said plate, limiting rollers extending along and parallel to longitudinal sides of said plate above said plate for holding a patient from opposite sides upon said plate, means rotating said limiting rollers with a speed practically equal to the speed of movement of said sheet but in a direction opposed to the direction of movement of said sheet, said sheet being wound upon said limiting rollers, other rollers constituting guide rollers for said sheet and extending parallel to said limiting rollers, means tensioning said sheet, means sensing the direction of rotating and the examining position of the first-mentioned rollers, switching means connected with the first-mentioned means and said switching means for switching on the first-mentioned means and for automatically switching them off when a desired examining position when the patient is to be taken up, is reached, swinging levers located at least upon one side of said plate and connected with at least one of the first-mentioned rollers for swinging it outwardly and below said plate, at least one side roller extending along and parallel to a longitudinal side of said plate and having an upper circumferential portion extending substantially in alignment with said plate, an axle carrying said side roller, an axle carrying one of said guide rollers, an axle carrying one of said limiting rollers, two swinging levers rigidly connected with the first-mentioned axle and connected with the second-mentioned axle for moving said one guide roller, two other swinging rollers rigidly connected with the second-mentioned axle and connected with the third-mentioned axle for moving said one limiting roller, and stops adapted to be engaged by said swinging levers for limiting the movements of said swinging levers, said stops being adapted to hold said one limiting roller in an outwardly swung position directly close to said side roller and to hold said one limiting roller in an inwardly swung position directly above said plate.
