Application lel October 6, 1921. Serial No. 505,862.
To alli/17mm t may conccm Be it known that l, SvANrn GUs'rAr Hnau MAN OnnLL, a subject of the King of Sweden, residing at Stockholm, Sweden7 have invented new and useful improvements in Bed Carriages, ot which the following is a specification.
The present invention relates to a bedcarriage havin Tables for elevating the beds and supporting them at a desired level said gables being movable at their lower ends in guides in the trame of the carriage in a direction to and from each other and being hinged each to a supporting member above their lower ends said supporting members in their turn being hinged to the frame ot the carriage. By rotating the supporting members upon the trame ot the carriage the raising` and lowering ot the gables will be effected. By hinging the gables to the supportingmembers at the half height of the former and making the height of the supporting members correspond to the halt height oiE the gables, the upper edges of the gables will move in a vertical plane during the raising or lowering of the gables. By this system of elevation mechanism distinct advantages are gained, inasmuch as the bed during transport rests with the steadiest part ot its bed-'frame on the bed-carriage. The bed-carriage can be built in a very stable fashion. leaving room for the eventually downwardsinking portions of the beds and the supporting-parts will possess a certain flexibility. all of which combine to ensure the bed being moved along smoothly during the process oi transport. Further7 if so desired. great elevation height can be obtained and the elevationby reason of the elevation mechanisms being managed each one tor itselt--can-be carried out with relatively little power and the bed-carriage can be so designed that it can be kept under a bed in the hospital ward ot" the department. From a sick-nursing point of view it is also an advantage that the carriage does not take up any eXtra space in the hospital ward and that the nursing-stati can manage it and attend to the transport of the patients7 but with this difference from the littercarriagrije7 namely, that the patient does not require to be lifted more than to and from the eX amination and operation tables.
The invention is illustrated on the accompanying drawing. Fig. 1 is a perspective view of a bed-carriage according to the invention. Figs. 2 and 3 are diagrams. lis the trame of the bed, Q frame-supporting wheels, 8 the two gables, which are movable at their lower ends by means of rollers l in guides 5 in the trame l in a direction to and froml each other. The gables are hinged at 6 to the supporting members 7, which have a lower shaft 8 journalled in stationary bearings 9 in the trame l. The shafts 8 and bearings 9 form the hinged connection between the gables and the frame. On one side ot the bed-carriage there are two levers l() attached to the ends of the shafts 8. By
means of these levers the shafts 8 can be rotated for raising or lowering the gables. l1 is a side trame, on which hooks 12 are mounted to be turned in a vertical plane to catch a pin 13 on the levers l() for maintaining the latter in a. desired position with the upper edges of the gables supporting the bed at the desired level. For releasing the hooks l2 -from the pins 13 the hooks may be provided with a handle (not shown) eX- tending outside the lever in the locked position. ln the example shown the gables are hinged to the supporting members at the halt height of the former and the height ot the supporting members 7 is equal to the halt' height ot the gables. lt' desired other means can be substituted for the levers 10 to rotate the supporting members 7. The both members 7 can also be connected with each other (not shown) to be rotated in unison by means of a single lever or other means. Many other variations ot the details can be made within the scope ot the invention.
ln Fig. 2 the gable is represented by line a, the supporting member by line and the guides by line c. o is connected with a at its han height and b=g From ai@ fun and dotted lines in this figure it is seen that the upper end of a, i. e. the upper edge of the gable, moves in a vertical plane. This fact is based on Euclides Prop XXXll Tome lll. From Fig. 3 it is seen that 7when Z) is turned upwards from a position where a lies on c, the upper end of a will move a distance d' for the iirst 30, a distance e for the next 800 and a distance f for the last 300. (Z is greater than e and e greater than f. Consequently, in the lower positions ot the gables and their supporting members there will be a greater vertical movement of the upper edge of the gable for a certain angle movement of the lever than in the higher positions. In the practical execution of the bed-carriage this may be of importance to bear in mind, as on account or' the space it ma be advantageous to obtain a considera le elevation with but slight movement of the lever.
What I claim is l. A bed-carriage having gables for elevating the beds and supporting them at a desired level said gables being movable at their lower ends in guides in the iframe of the carriage in a direction to and from each other and being hinged each to asupporting .member above their lower ends, said supportingY members in their turn being hinged to the rrame of the carriage for the purpose of raising and lowering` the gables by rotating the supporting members upon the frame of the carriage.
2. A bed-carriage according to claim l, characterized in that the gables are hinged to the supporting members at the halt height of the former and that the height of the supporting members corresponds to the half height of the gables, in order that during the raising or lowering of the gables their upper edges may move in a vertical plane.
In testimony whereof I have signe-d my name to this specification.
