Definitions
- the invention relates to a device for the detachable connection of a stretcher on a stretcher chassis with at least one, preferably two connecting elements arranged on the stretcher chassis and with at least a corresponding number arranged on the stretcher and correspondingly designed with the connecting elements on the stretcher chassis.
- the stretchers When transporting stretchers in ambulance vehicles, it is common for the stretchers to be inserted into the ambulance vehicle together with a stretcher chassis and for the ambulance transport frame to be locked in the ambulance vehicle.
- the stretcher is usually designed such that it is positively arranged in the stretcher trolley.
- This embodiment has proven to be advantageous in that the stretcher can be quickly and easily lifted out of the stretcher chassis at the place of use, for example to serve to accommodate the accident patient to be rescued.
- the stretcher After the accident patient to be rescued is bedded on the stretcher, the stretcher is placed on the stretcher and the stretcher and the stretcher are pushed into the patient transport vehicle, whereby the stretcher usually moves from an unfolded position to a folded position and with the patient transport vehicle the ambulance arranged fastening devices is locked.
- the invention has for its object to provide a device of the generic type, which provides increased safety in an ambulance, particularly in the event of accidents.
- the solution to this problem provides that the latching elements can be automatically latched into the connecting elements automatically and under pressure and that the latching between the latching elements and the connecting elements can be manipulated to release the latching.
- a device according to the invention therefore has the advantage that a secure connection is provided between the stretcher and the stretcher chassis, which enables automatic locking.
- the device according to the invention thus enables a complete and secure anchoring of the patient, in particular in connection with a locking of the stretcher chassis in the patient transport vehicle, so that even in the event of accidents of the patient transport vehicle an uncontrolled movement of the patient carrier with the patient loading it or only the patient carrier is avoided. Due to the manipulable latching, the device according to the invention can be operated in such a way that the advantageous properties of a combination of a stretcher and a stretcher chassis are retained at the location of the accident, namely in that the stretcher can be detached from the stretcher chassis very quickly.
- each connecting element is designed as a profile element which is substantially rectangular in cross section, the narrow sides of which are arranged essentially at right angles to one side with a slot designed to be open on one side for receiving the latching element, the slot being closed at its closed end End has a hook element which is releasably connectable to the latching element and is pivotable about an axis running essentially parallel to the surface normal of the side connecting the narrow sides.
- a hook element which is actuated by the latching element in such a way that when the latching element hits the hook element, this hook element blocks the latching element in the connecting element.
- the hook element of the connecting element can be released by means of a simple cable pull, so that the latching element can be pulled out of the connecting element after actuation of the cable pull or another triggering device.
- the slot is designed to widen in a V-shape towards its open end.
- the hook element is designed as a spring-loaded pawl which can be pivoted about the axis and which is connected to a release element.
- This configuration serves in particular to simplify handling and to simplify the construction of the device.
- the trigger element has a handle which protrudes outside the profile element. This handle can be actuated either directly or via a force transmission element, for example a bouwden cable, a linkage or the like.
- the release element is displaceable in the transverse direction of the profile element, the release element preferably being guided in a bore in the profile element.
- a prestressed tension spring is arranged between the release element and the profile element, which ensures that the release element connected to the pawl automatically moves the pawl into a locking position.
- This locking position leaves the pawl only at the moment when the locking element strikes an inclined surface of the pawl arranged in the direction of the slot opening and this pawl is pressed out of the locking position due to the inclined position of the surface.
- the tension spring pulls the pawl into its locking position, the force of the tension spring being transmitted to the release element, which release element is positively connected to the pawl.
- the locking elements are preferably attached to a frame on the underside of the stretcher. Furthermore, it is provided that the locking element each have a base body that can be attached to the stretcher. The locking elements are adjustable relative to the base bodies.
- the locking elements from a threaded rod or Threaded rod section and a preferably round plate, which is optionally attached to the threaded rod or the threaded rod section with the interposition of a rod element, the outer dimensions, in particular the diameter of the plate being larger than the diameter of the rod element and / or the threaded rod or the threaded rod section and the Width of the slot in the area of the hook element.
- the threaded rod or the threaded rod section can preferably be screwed into a threaded bore in the base body, so that the latching element can be adjusted with respect to a precise position relative to the connecting element.
- the base body consists of two halves which can be connected, preferably screwed together, and which encompass a structural element of the stretchers.
- Connection and locking elements also has the advantage that with two locking elements and two connecting elements, the connection between stretcher and stretcher chassis can be made very quickly, without extensive threading work is necessary, which adversely affect quick handling of this rescue device. Further features and advantages of the invention result from the following description of the accompanying drawing, in which a preferred embodiment of the transport lock according to the invention is shown.
