Definitions

  • An adjustable table has a table top with a downward extending side member and a base including on each side lower roller supports for engaging a curved drive surface of a side member and an upper pivot support for engaging a slot in the side member.
  • the supports have fixed positions and cooperate with the drive surfaces and slots, such that the table top is movable between horizontal and vertical orientations without any part extending below the lower support.
  • driving gears which start simultaneously the tilting movement and the displacement, terminating the same simultaneously when the supporting surface is in the vertical position.
  • the rates of both movements have in this case a fixed ratio, the consequences of which are described more fully with reference to FIGS. 1 and 2.
  • Tables symmetric on both sides and have a supporting face adapted to be tilted into the vertical position in both directions about an axis of rotation located centrally beneath the patient supporting surface at a height above the floor which is smaller than half the length of the supporting surface and may be provided with a rotary shaft arranged at a maximum height or with a rotary shaft located at a small height above the floor.
  • FIG. 2 illustrates an identical series of positions of the supporting surface tilted about a rotary shaft at a smaller height.
  • FIG. 3 shows a supporting table with the moving mechanism
  • FIG. 4 shows the supporting surface in different positions during the tilting movement.
  • a driven toothed rim adapted to rotate about the horizontal shaft, is provided with a sledge in which the supporting surface is adapted to slide.
  • the second embodiment comprises a stationary toothed rim along which the supporting surface rolls downwards and simultaneously slides in a sledge.
  • the invention relates to a patient supporting surface table comprising a supporting surface adapted to be tilted on both sides out of a horizontal position into a vertical position, which surface bears in the horizontal position at two points located on the same level side by side.
  • the supporting points do not form, at the same time, the two axes of rotation about which the supporting surface is tilted out of the horizontal position.
  • the invention has for its object to provide a table of simple structure, while during the tilting movement the supporting surface is suitably shifted in order to obtain a flat curve of movement and said disadvantages are avoided.
  • the grooveshaped recess in each wall extends along a straight line from a higher point towards a point forming the point of intersection of a line at right angles to the supporting surface and a line parallel to the supporting surface, said lines being spaced apart from the place occupied by the active driving roller in the vertical position of the supporting surface by a distance equal to the difference in height between the third supporting point and the plane of the rollers, and by half the distance between the rollers respectively.
  • the edge of the vertical wall is curved away from the two ends of the supporting surface in the form of a circle or an ellipse.
  • the driven rollers may be coupled with the edge of the vertical wall by mutual toothings.
  • a base formed by two columns 2 and 3, which may be interconnected by transverse beams 4, is provided.
  • the vertical side partitions 5 have end and lower driving surfaces which bear on lower support rollers 6 and 7, associated with the driving gear for producing the tilting and shifting movements of the supporting surface 1.
  • a worm shaft 9 transfers the force of an electric motor 8 to a worm wheel 10, which drives the shaft 11, which is provided, apart from this wheel, with two driving rollers 6.
  • the shaft 11 has furthermore a sprocket wheel 12, which transfers by means of a chain 13 the rotation of the shaft 11 to a second sprocket 14, arranged on a driven shaft 15, also having two driving rollers 7.
  • the driving rollers 6 and 7 are adapted to engage by teeth the edges of the side partitions 5.
  • the figure shows a chain 16, fastened along the periphery of one of the partitions 15, the links of which chain co-operate with the toothed driving roller 6.
  • a further conventional driving gear is formed by the gearwheel and toothed rim structure.
  • the third upper supporting point is located in the top of the columns 2 and 3 and is formed by a horizontal shaft 17, located centrally beneath the supporting surface 1 in the horizontal position thereof and bearing on the two columns 2 and 3. This is not necessary, since in the two columns a short stub shaft may be secured, the supporting ends of which project in slots 18 in the side partitions 5.
  • the slot 18 is curved and its ends project downwardly, the axis of which extends between two points on the side member.
  • the reference points 20 define the positions of the driving rollers 6 and 7 at the curved end surfaces when the table top 1 is vertical. in horizontal position of the table top, the rollers engage the side member at the points 20.
  • the slot end as defined by 21 is located at a horizontal distance a from the reference point 20, a corresponding to the vertical distance of the support 17 relative to the level of the supports 6 and 7.
  • Point 21 is at a vertical distance b from the reference point 20, corresponding to half the distance B between the supporting rollers 6 and 7.
  • the movement of the supporting surface 1 is performed in the manner illustrated in FIG. 4.
  • the initial displacement of the supporting surface is such that during the tilting movement the end of the supporting surface does not project beyond the space required for the side partitions 5. This may be varied by the choice of the place of the driving rollers 6 and 7 and the place of the horizontal shaft 17.
  • An adjustable table comprises:
  • a side member fixedly extending downward from the table top, having curved drive surfaces at the end and lower parts thereof, and including a slot;
  • a base having a lower support part, and an upper support part including a pivot means in a fixed location above and laterally displaced from said lower support, the height between said supports being less than half the table top length;
  • the table top being pivotally mounted on the base with the lower support engageable to said drive surfaces and the upper support engaging the slot;
  • the axis of the slot defined by a line extending angularly downward between two points on the side member, the first point being located where the pivot means engages the member when the table top is horizontal, the second point being located (when the table top is vertical) the same vertical and horizontal distances as the upper support is above and laterally displaced from the lower support, whereby when the table top is moved between horizontal and vertical positions, no portion of the table top and the side member extends below the lower support.
  • the table top has a second side member similar to and spaced from the first;
  • the base has second lower and upper support parts similar to and spaced from the first and cooperatively engaged to said second side member.
  • said support means includes a drive wheel for engaging each of said drive surfaces, and motor means for rotating said wheels.
  • An adjustable table comlprisingz a. an elongated table top avlng a side member fixedly extending downward with curved drive surfaces on the end and lower parts thereof, and connection means spaced from said drive surfaces; and b. a base having a lower support part in a fixed location and an upper support part including a pivot means in a fixed location, the height between said supports being less than half the length of the table top; c. the table top being pivotally mounted on the base with the lower support sequentially engaging portions of said drive surfaces and the upper support engaging said connection means; said lower support including means at said fixed location for engaging said drive surfaces to move relative to the base and thereby pivot the table top between horizontal and vertical positions with no portion of the table top or side member extending below the lower support.
  • a table as defined in claim 7 further including power means for driving said lower support means to pivot said table top.
