Definitions

  • ABSTRACT A supporting table for patients has between its base and the table plate a height raising and lowering mechanism which includes rods forming two parallelogram sections connected one behind the other, a connecting member mechanically fixing the upper bearing of the lower section relatively to the lower bearing of the upper section, a motor connected with one of these sections and a power transmitting connection between these sections.
  • Such tables are used, for example, in surgery as well as in irradiation devices and examining devices to securely support the patient in a suitable position.
  • Existing supporting tables have as a rule raising and lowering devices used to adapt the location of the patient to the various requirements.
  • the existing raising and lowering devices change the height level only to a small extent. They are hydraulically, mechanically or electromechanically operated.
  • Austrian patent specification No. 214,023 describes a supporting table for patients wherein the table plate is swingable about a horizontal axis and wherein a chelate rod connection is used for height setting.
  • Such rod connection has, however, the drawback that it takes a great deal of space and that it is comparatively expensive and complicated as far as its structure is concerned. It is therefore badly suitable for certain uses, particularly when utensils must be placed under the table.
  • This Austrian patent specification also describes a parallel rod guide. However, this guide is not used for the height setting of the table but is connected with a device for swinging the table. Thus the parallel rod guide is an addition to the chelate rod connection.
  • An object of the present invention is the provision of a supporting table for patients having means for raising and lowering the table to a great extent so that devices having a great length, as for example, an isotope camera can be placed under the table, while space required for the raising and lowering means is small.
  • the supporting table of the present invention can be used in connection with an isotope camera.
  • the specific connection of the parallelogram rod sections includes a yoke and levers connected with the sections, providing a particularly simple and space saving embodiment of the present invention.
  • the sizes of the yoke and levers are determined by the size of the stroke for raising and lowering the table.
  • the parallel sections have U-shaped interengaging shapes. This construction is particularly effective as a protection against accidents.
  • FIG. 1 is a side view of an apparatus wherein the supporting table of the present invention is used.
  • FIG. 2 is a front view.
  • FIGS. 3 and 3a are diagrams illustrating the operation and size of the double parallelograms of the raising and lowering mechanism.
  • FIG. 4 is a section through one of the parallelogram rods.
  • the supporting table 1 for patients is combined with an isotope camera 2.
  • the camera 2 consists of the actual camera head 3 and a support 4 which is shiftable vertically along a column 5, so that it can be moved from an upper position 3 shown by full lines to a lower position 3 indicated by broken lines in FIGS. 1 and 2.
  • the supporting table 1 for patients consists of a base 7 movable upon the floor by an air seating and carrying the raising and lowering mechanism 8 which extends as an intermediate part to the actual table 9.
  • the table 9 is shown in full lines in its normal lower position and is indicated as 9 by broken lines in its raised position.
  • the actual raising mechanism 8 includes a support 10 fixed to the base 7, a trapeze-shaped connection 1 1 and a support 12 firmly fixed to the table 9.
  • Parallel guides 13 and 14 provide a connection between the support 10 and the connection 11 while parallel guides 15 and 16 provide a connection between the connection 11 and the support 12.
  • the first support 10 carries a rotary bearing 18 for the guide 13.
  • the guides 14 and 13 are connected to rotary bearings 19 and 20, respectively, carried by the connection 11.
  • the connection 11 also carries rotary bearings 21 and 22 opposite the bearings 19 and 20.
  • the bearing 21 is connected with one end of the guide 16 the opposite end of which is connected with a rotary bearing 23 carried by the support 12.
  • the bearing 22 is connected with one end of the guide 15 the opposite end of which is connected with a rotary bearing 24 carried by the support 12.
  • the parallel guides 13, 14 and 15, 16 are of U-shaped outline, with the open U-sides of the parts being directed toward each other and interengaging.
  • the supports 10 and 12 as well as the connection 11 are also U-shaped so that on both sides of the legs of the U-shaped profile of the guides 13 to 16 there is one supporting plate of the supports 10 and 12 as well as of the connection 11, as indicated by 10 and 10' in FIG. 4. Due to this construction the rods are closed on all sides so that there is no danger of accidients resulting from improper grasping.
  • the action of the mechanism 8 is provided by the two parallel guides 13 and 14 the rotary axes of which are constituted by bearings 17 and 18 of the support 10 connected with the base 7.
  • the two sides are moved relatively to each other by a ball bearing spindle 25, in that the motor 25 rotates the threaded rod 28 through the gear drive 27 in a direction corresponding as to whether the table 9 is to be raised or lowered.
  • This causes a swinging of the guide 14 about its bearing and at the same time the lever 29 which is rigidly connected with the guide 14 and extends beyond the bearing 19, will turn the bearing 30 and move upwardly the yoke 31.
  • the parallel guides 13 to 16 are of equal length and there are equal distances between the guides 13 and 14 as well as guides 15 and 16. There are corresponding equal distances between the bearings 17 and 18, 19 and 20, 21 and 22 as well as 23 and 24.
  • the movement of the support 12 and consequently that of the table takes place at least approximately along a vertical line.
  • the angle which the lever 33 forms with the parallel guide 15 is so selected that in the lowermost, namely, the basic or initial position the lever 33 extends in the direction of the line connecting the bearings 19 and 22 (FIG. 3a).
  • the lever 29 forms an angle with the above-mentioned connecting line between bearings 19 and 22 which corresponds with that through which the guides are moved when the stroke has reached its maximum position (maximum stroke angle).
  • the lever 33 will form the maximum stroke angle with the connecting line between bearings 19 and 22.
  • the length of the parallel guides 13 to 16 determines the absolute height of the stroke while the mutual distances of the guides 13, 14 and 15, 16 are selected when taking into consideration the division of mechanical load upon the supports 10 and 12 as well as the connection 11.
  • a supporting table for patients having a base, a table plate and a mechanism located between said base and said table plate for moving said table plate up and down relatively to said base, said mechanism comprising rods forming two parallelogram sections located one above the other, bearings carried by ends of said rods, a connecting member connecting the upper bearings of the lower section with the lower bearings of the upper section, a motor, a drive connecting said motor with one of said sections and power transmitting connecting means between the two sections.
  • said power transmitting means comprise a yoke, a lever constituting a continuation of one of the rods of the lower section and pivotally connected with one end of said yoke, and another lever extending at an angle from the lower end of one of the rods of the upper section and pivotally connected with the other end of said yoke.
