Definitions

  • the invention relates to a driving device for a stretcher, with a frame, front and rear legs, which are articulated to the frame and lockable, and two placement rollers at the front end of the frame, (FR-A1-2 546 402).
  • a stretcher can be comfortably rolled, for example to the accident site or, in the case of a patient lying on the stretcher, to the patient transport vehicle.
  • the stretcher on the frame of the driving device is pushed together with the driving device onto the stretcher rack in the patient transport vehicle.
  • the driving device initially rests on the rear end of the stretcher support frame with its two mounting rollers fixedly attached to the front end of the frame and when the driving device is pushed further into the patient transport vehicle the front and rear legs articulated to the frame are pivoted up from the rear edge of the stretcher support frame to below the frame.
  • the placement rollers arranged at the front end of the driving device are advantageous when placing the driving device on the stretcher support frame, since the driving device stands securely with the touching rollers on the stretcher support frame when the front legs swivel up and no longer support the driving device against the ground.
  • the support rollers protrude further into the vehicle than the rollers on the stretcher. Since the conventional stretcher support racks are only intended for pushing on the stretchers, their guide rails which hold the rollers are shorter than is necessary for pushing on a driving device.
  • the use of the known driving devices thus requires at least one change, ie extension of the stretcher support frame and possibly even complete replacement of the stretcher support frame in the patient transport vehicle.
  • the invention has for its object to provide a driving device for a stretcher according to the preamble of claim 1, which does not require an adapted or modified stretcher rack.
  • the invention provides that the mounting rollers on the frame are guided in a longitudinally displaceable manner and can be locked at the front end of the displacement path relative to the frame by a locking device.
  • the placement rollers are not rigidly attached to the frame, but are guided on it in a longitudinally displaceable manner.
  • the placement rollers At the front end of their displacement path, at which the placement rollers are located at the height of the front end of the frame, they can be locked relative to the frame by a locking device that can be operated and released, for example, by hand.
  • the support rollers are in the locked state at the front end of the displacement path when the driving device is pushed onto the rear end of the stretcher support frame pulled out of the patient transport vehicle.
  • the distance between the mounting rollers and the pivot axis of the front legs on the frame is maximum, so that the driving device lies reliably on the carrier storage frame via the mounting rollers if the front legs are pivoted up when the rear edge of the carrier storage frame is touched. At this moment, the driving device lies on the stretcher support frame with its support rollers, while the rear legs are on the road; the driving device is therefore safe. When the driving device is pushed further up onto the stretcher support frame, the locking device is released so that the placement rollers are no longer fixed relative to the frame.
  • the driving device can therefore be pushed even further into the patient transport vehicle when the placement rollers touch the front end of the stretcher support frame; then namely the placement rollers move relative to the frame, ie in the fully inserted state the front end of the frame projects beyond the placement rollers.
  • the driving device adapts to the length of the conventional stretcher storage racks.
  • a stretcher support frame that is only suitable for holding a stretcher can thus also be used for holding the driving device according to the invention. Changes to the stretcher storage racks are not necessary.
  • the two requirements are met, on the one hand, to make the distance between the placement rollers and the front legs large when the driving device is placed on the stretcher support frame, so that the driving device rests securely when the frame is not supported by the front legs when they are swung up. Due to the longitudinal displaceability of the placement rollers relative to the frame, the other requirement is also met, the stretcher support frame unchanged, i.e. training just as short as before. Because when the driving device is retracted, the support rollers are located directly below the front rollers of the stretcher, i.e. retracted with respect to the front end of the frame of the vehicle. This has the advantages that the stretcher storage racks already installed in the patient transport vehicles can also be used for the driving device according to the invention and that the space available, in particular the space for the caregiver in the patient transport vehicle, is not reduced.
  • the placement rollers are advantageously resiliently biased towards the front end of their displacement path. As a result, when the driving device is pulled out, the placement rollers automatically assume their position again at the front end of the frame, where they are again locked by the locking device.
  • the locking device is coupled to a locking device for locking the front legs.
  • the support rollers are secured against displacement at the rear end of their displacement path when the front legs are pivoted up under the frame.
  • the placement rollers are at the level of the front rollers of the stretcher and immediately below them.
  • the mounting rollers are rotatably mounted on the two ends of an axis transverse to the frame, which is connected to a first sliding body which is guided in a longitudinally extending hollow profile bar and can be locked by the locking device.
  • the frame consists essentially of two longitudinal spars and one between the longitudinal spars and parallel to this extending hollow profile bar, in which a first sliding body is slidably guided, which is connected to an axis running transversely to the frame and arranged under the frame, at the ends of which a mounting roller is rotatably mounted.
  • the hollow profile strip has at least one downwardly open channel in which the sliding body is captively located.
  • the hollow profile bar gives the whole frame a compact structure that gives it the necessary strength.
  • the locking device is arranged on the hollow profile bar. Even more stability is given to the frame and thus to the entire driving device if the transverse axis is supported by support rollers from below on the two longitudinal spars. This largely prevents lateral tipping movements when the driving device is resting on the support rollers on the stretcher rack.
  • support struts are articulated on the front legs, which are movably connected to a second sliding body held displaceably in the hollow profile strip, which can be determined by the locking device which, when the front legs are pivoted down, the second sliding body and When the front legs are swung up under the frame, the first sliding body for the mounting rollers is locked.
  • the first sliding body rests against the second sliding body and the front end of the hollow profile strip when the front legs are pivoted down and locked and that the second sliding body rests against the first sliding body when the front legs are swung up under the frame.
  • the other sliding body, on which the locking device does not engage is simultaneously secured against displacement.
  • support struts are articulated on the front legs and are connected to the placement rollers.
  • the support struts which move relative to the frame when the front legs are pivoted, are connected to the axis on which the mounting rollers are mounted.
  • the placement rollers move automatically relative to the frame when the front legs are swung up when the driving device is pushed into the patient transport vehicle. In this way, a forced coupling between the pivoting of the legs and the displacement of the placement rollers is established.
  • the support struts are movably connected to the first sliding body, which in turn is connected to the axis of the placement rollers and is displaceably guided in the hollow profile strip. If the placement rollers are at the front end of the displacement path and are secured against displacement, the front legs are in the swung-down state, and they are also locked are. With the front legs swung up under the frame, the support struts are located at the rear end of the displacement path due to the forced coupling of the support struts to the mounting rollers. Even in this position of the front legs and the placement rollers, these elements are secured against movement by the locking device.
  • the set-up rollers are advantageously connected to a stop element which interacts with a locking part arranged on the stretcher support frame and which prevents the set-up rollers from moving back to the front end of the displacement path.
  • the stop element touches a locking part, for example a hook arranged on the stretcher support frame.
  • the frame moves with respect to the mounting rollers, as a result of which they are brought into their position at the rear end of the displacement path.
  • the placement rollers automatically assume the position at the rear end of the displacement path when the driving device is pushed into the patient transport vehicle.
  • the front end of the stretcher support frame can also serve as a locking part, against which the placement rollers collide when the driving device is inserted.
  • Fig. L shows the driving device with a stretcher thereon and locked legs pivoted down.
  • the driving device has a frame 10 which consists of two longitudinal bars 12 which are round in cross section (only one longitudinal bar is shown in the figures), a front transverse bar 14 and a rear transverse bar 16 exists.
  • a hollow profile strip 18 runs parallel to the longitudinal spars 12, the two ends of which are connected to the transverse spars 14 and 16.
  • the hollow profile strip has two channels 20 and 22 which are essentially circular in cross section and run parallel to the longitudinal bars 12 and are open at the bottom.
  • a plurality of sliding bodies in the form of short tubes are slidably held.
  • the channels each have a closed wall which extends over an angular range of approximately 270 °, so that the sliding bodies are held captively.
  • two front legs 24 and two rear legs 26 are rotatably supported, of which only one leg is shown in the drawings.
  • the rear legs 26 are articulated directly on the longitudinal spars 12 via joints 28.
  • a fork-shaped holder 30 on which a roller 32 is rotatably mounted.
  • the brackets 30 are rotatably attached to the legs 26 about a vertical axis 34.

  • the two rear legs 26 are connected to one another by a cross strut 35.
  • Support struts 36 are rotatably attached to the cross strut 35.
  • the two free ends of the support struts 36 are connected via an axis 37 which is connected to a sliding body 38 located in the channel 22 of the hollow profile strip 18.
  • a support roller 40 is fastened, which rest against the longitudinal spars 12 from below and roll on the longitudinal spars 12 when the rear legs 26 are pivoted.

  • the axis of the two support rollers 46 is connected to a sliding body 48 which is slidably arranged in the channel 20 of the hollow profile strip 18.
  • the two front legs are connected to one another via a cross strut 49, with which in turn two support struts 50 are connected in an articulated manner.

  • a support roller 54 is rotatably supported, which, like the support rollers 46 and 40, abuts against the longitudinal spars 12 from below.
  • the second sliding body 52 can be locked by a locking device in the channel 20 of the hollow profile strip 18.
  • the locking device consists of a rod 55 (FIG. 4), which runs parallel to the channels 20 and 22 and is rotatably held in the hollow profile strip 18, at the rear end of which a (not shown) Operating lever is arranged, which is located below the rear cross strut 16 of the frame 10 and is operable by hand.
