Abstract

Loading device for stretcher chairs for ambulance vehicles, characterized in that the loading device consists of an upper tray (1) and a lower tray (2) which are connected on the underside by a hinge joint (7) which is attached to the underside of the upper tray (1) and the lower tray (2), the upper tray (1) having additional joints (3) towards the main bracket (10) attached in the ambulance vehicle.

Description

Loading devices for stretcher chairs on which inoperable patients are placed in the ambulance vehicle are known. The known loading devices are basically mounted in the rear area of the patient transport vehicle vertically standing in a corresponding holder and can be pivoted by 90 ° after opening the rear door to the outside. The swing-out part of the loading device is tray-shaped and has on the steering sides stable guide webs to give the stretcher chairs a corresponding guide when entering the ambulance.

The rollable stretcher chair is moved with the patient sitting thereon to the ambulance vehicle and 2 people lift the chair with the patient on the tray and the chair is then rolled into the interior of the ambulance vehicle. Raising the stretcher chair becomes difficult when the patient is heavy weight.

The invention has as its object to provide a loading device for stretcher chairs for ambulance vehicles, which in addition to the lifting of the stretcher chair on the tray-shaped loading area also allows the stretcher chair with the patient sitting on it from the floor without lifting, are rolled into the interior of the ambulance vehicle can.

The problem is solved with the features listed in the protection claim 1.

The advantage of the invention is that the loading device can be brought by swinging the double tray by 90 ° in the known horizontal plane and is lifted to this level of the stretcher chair as before and that in heavy people it is possible by unlocking and swinging the lower tray create a ramp on which the heavyweight patients can be rolled in and out of the ambulance vehicle.

An advantageous embodiment of the invention is shown in the protection claim 2, to move the loading device easier and able to lock.

A further advantageous embodiment of the invention is mentioned in the protection claim 3 and creates conditions for easy operation of the locking shaft and for locking and unlocking the two trays.

The embodiment in the protection claim 4 facilitates the movement of the lower tray and allows the locking and Entarretierung with the upper tray.

An embodiment of the invention will be described with reference to 1 to 5 explained.

Show it:

1 the loading device with horizontal loading area,

2 a top view of the loading device with horizontal cargo area,

3 the loading device with folded-out trays in inclined position,

4 the loading device with a top view of the lower tray,

5 the loading device shown in perspective,

In the figures, the loading device is with the upper tray 1 , the lower tray 2 , the hinged joint 7 , the main mounting 10 and the additional joint 3 to see.

As in the 1 and 5 can be seen, the loading device according to the invention is folded and stored in the main holder 10 which is fastened in the rear area of the ambulance vehicle, not shown here.

After opening the rear door of the vehicle, the upper tray 1 , which by locking with the lower tray 2 connected manually to 90 ° by means of handle 4 and by supporting an installed gas spring 14 folded down.

When transporting a heavyweight person, the lever 5 grabbed and moved upwards, resulting in over the locking shaft 11 the locking hooks 13 from the two sides of the lower tray 2 attached latching elements 6 to solve.

After releasing the lock by the lever 5 the lower tray dissolves 2 from the abutments 9 and over the attached additional joints 3 can the upper tray 1 and the lower tray 2 be tilted in the inclined position to the floor.

The lower tray 2 This is done manually by means of a handle 8th swiveled by 180 °.

When panning is done by 180 °, the lower tray forms 2 with the upper tray 1 an inclined ramp resting on the floor and the stretcher chairs can be rolled into the patient transport vehicle with the heavyweight persons.

The folding and locking of the loading device and pivoting back into the patient transport vehicle not shown in detail is then possible in a simple manner.
