Zur Ausschaltung der Federung kann, wiëtMr ; wibereits beschrieben, der Hebel 24 in die Lage 24'geschwenkt werden. In Fig. 1, the stretcher platform 13 is in the horizontal position of use shown. It is based on this by means of the set or sets 20 or the like rear vehicle floor 12 from, while the front end of the stretcher platform means the link or links 17 and the elastic buffer or buffers 22 are resiliently supported is; ; in that the joint 19 to the extent of the flexibility of the elastic buffers 22 about the joint 18 in the vertical direction more or less limited swing karin. To switch off the suspension, wiëtMr; As already described, the lever 24 be pivoted into position 24 '.

In der waagerechten Lage können ferner die das Oberteil 15 bildenden- rungsschienen der Tragenbühne 13 mit Bezug auf das Unterteil 12 nach vorn in die Lage 15" vorgeschoben oder - insbesondere zum Beladen bzw. Entladen der Tragenbühne - in eine rückwärtige, aus der. hinteren Fahrzeugtür herausragende Lage 15"' verschoben werden.

Claims

A stretcher platform for ambulances that runs across from the vehicle one or more resilient elements is elastically supported, has the advantage that Shocks and vibrations that affect the body while driving the suspension can only be transferred to the stretcher platform in a damped manner and a Calm, practically vibration-free positioning of the sick or injured is guaranteed will.

However, the resilience is a problem for some treatments Sick, e.g. B. for an external heart massage, unsuitable; under . Circumstances would they also prevent such treatment.

The object of the invention is to provide spring-supported stretcher platforms to make it more universally applicable for ambulances by adding them according to the needs can be used with or without suspension.

The object is achieved by the invention specified in claim l. Advantageous further developments of the invention are described in the subclaims.

The drawing shows an embodiment of the invention, namely 1 shows the side view of the stretcher platform arrangement and FIG. 2 shows an enlarged partial view the front stretcher platform arrangement according to FIG. 1.

As is known in an ambulance is behind the driver's seat a standing or sitting room 10 is provided, which is backed by a front, approximately vertical Wall 11 of a rear, raised vehicle part serving as the floor of the interior space 12 is limited. The rear end of the vehicle is in a known manner completed by a (not shown) vehicle door.

The stretcher platform 13 consists essentially of a lower, non-displaceable one Part 14 and a displaceable in this in longitudinal guides upper part 15, the Has longitudinal guide rails for the stretcher platform 16.

For the front storage or support of the stretcher platform 13 is used front link or

Link pair 17, which is at the front end of the rear vehicle floor 12 mounted in a hinge 18 and attached to the lower part 14 by means of a hinge 19 the stretcher platform is connected in an articulated manner.

The rear end of the stretcher platform 13 is by means of one or more, possibly also elastic lugs 20, feet or the like loosely on the rear Vehicle floor 12 supported so that the stretcher platform 13 around the front, through the Joint 19 of the link or links 17 formed horizontal transverse axis - z. B. Can be tilted by means of a pair of support arms, such as this one, for example is indicated by the dot-dashed position 13 'of the stretcher platform.

For resilient support of the link or links 17 or the front resilient support of the stretcher platform3 is the link memberl7 each with one downwards directed arm 21 is provided on which an approximately frustoconical, optionally hollow rubber or plastic buffer 22 is attached as a resilient element. Of the The buffer 22 can be arranged on the arm 21 of the link 17 so as to be adjustable and is supported in the horizontal position of the link member 17 in the horizontal direction against the front, approximately perpendicular wall of the rear vehicle floor or against a corresponding one with the part connected to the vehicle. When bumps occur can therefore the stretcher platform 13 in the vertical direction according to the flexibility the elastic buffer 22 give way. To avoid excessive vibrations, you can the resilient elements or the elastic buffers can be provided with damping by she z. B. made of a plastic with strong internal damping, such as butyl od. Like., exist.

Should the suspension, especially if a cardiac massage one on the Stretcher lying sick is to be made, be turned off, lwill a hinged at 23 on the arm 21 of the link arm two-armed lever 24 with a designed as a handle lever arm 25 and a locking lever arm 26 from the illustrated extended position in the dash-dotted position 24 'pivoted.

As a result, the locking lever arm 26 is supported by means of a roller 27 in the position 26 'on the front boundary wall 11 of the vehicle floor and thus the handlebar 17 rigidly.
