DE1566422C3 - Stretcher platform adjustable in three longitudinal positions - Google Patents

Description

The setting of the stretcher platform in three longitudinal positions, in particular in a middle normal Transport or use position, a front care position and a rear loading and unloading position, was previously done by hand. This was particularly difficult insofar as a precise setting, especially the middle "position; special attention was needed so that the stretcher platform was not moved too far forward or too far backward. There was also a certain to move Effort required. Furthermore, the stretcher platform was often shifted jerkily, which was could have an unpleasant and harmful effect on the sick or injured.

It is known from US Pat. No. 2,387,082 to use stretchers on a vehicle in a vehicle Connect the stretcher platform to a cable to make it easier to slide the stretchers into the vehicle. However, the winding up of the rope also requires a workload that the staff additionally takes, apart from the fact that the stretcher platform is arranged and stationary in the vehicle due to specially laid ramp-like parts

; _: is required to drive the stretchers on and that the stretchers must be coupled to the rope. It is practically impossible to make it easier to move the stretchers. The movement by means of "the rope can also take place unevenly and jerkily.

It is also by the German Äuslegeschriftl 191 513 known, stretcher platforms by hydraulic means from an altitude close to the ground to be raised at about table height. But this is a lifting against gravity by means of a lifting device, which as a result of their different tasks a stimulus to There is no longitudinal shifting of a stretcher platform. The arrangement of a defined intermediate position is also missing.

The invention is based on the object of facilitating the displacement movements of the stretcher platform and thus to make it gentler for the sick or injured, especially for one

Claims (8)

Patent claims: 1. In three longitudinal positions, in particular in a mean normal transport or use position, a front care position and a rear loading and unloading position, adjustable Stretcher platform in ambulances, characterized in that a hydraulic, pneumatic or hydropneumatic adjusting device (33, 38) with only one cylinder-piston unit (33) is provided (Fig. 6) that one of the two elements (cylinder or Piston) this unit on the vehicle (at 34) or another relatively immovable Support part (14) supported and the other of the two elements with the stretcher platform (15) for displacement the same (at 36) is connected and that the middle of the three positions by a fixable center position of the piston is determined. 2. In three longitudinal positions, in particular in a middle normal "transport or use position, a front care position and a rear loading and unloading position, adjustable Stretcher platform, characterized in that one for adjustment to the three positions hydraulic, pneumatic or hydropneumatic adjusting device (21 to 28) with two cylinder-piston units (21, 23; 22, 24) is provided and in the middle position (Fig. 4) of the stretcher platform (15) which can be adjusted in three positions both pistons are in their cylinders each in an end position and for adjusting the Stretcher platform in its front position (Fig. 3) or rear position (15 'in Fig. 1, 2) either one or the other of the two pistons is moved into its other end positions. 3. Stretcher platform according to claim 2, characterized in that the two cylinders (21, 22) are combined directly one behind the other to form a cylinder row and one of the two pistons by means of its piston rod (23) on the relatively immovable support part (14) and the other of the two pistons is connected to the stretcher platform (15) by means of its piston rod (24). 4. Stretcher platform according to one of claims 1 to 3, characterized in that the or the; Cylinder, e.g. B. by means of sleeves (30), on the relatively immovable support part (14) or on the stretcher platform (15) are slidably guided in the direction of movement. ^v 5. Stretcher platform according to one of claims 1 up to 4, characterized in that the (relatively fixed) supporting part carrying the stretcher platform can be pushed (14) around a transverse axis (13), preferably by means of the same auxiliary force that moves the the stretcher platform mediated, is pivoted. 6. Stretcher platform according to one of claims 1 to 5, characterized in that it (40) in on in a known manner by means of two links (42, 43) from a first one, in particular one close to the wall Location, in a second, in particular protruding from a rear door opening, for loading and unloading serving layer (40 ') and optionally in an intermediate layer, e.g. a middle lere care situation, is pivotably mounted in an approximately horizontal plane and that for Pivot a on a pivot lever, for.
