| 121 | VIBRATION ISOLATION ARRANGEMENT | EP87907432.0 | 1987-11-12 | EP0331678A1 | 1989-09-13 | LEYSHON, David, Rhodri |
| Un agencement anti-vibratoire, par exemple pour supporter un brancard dans une ambulance, comporte un levier (16) qui s'étend entre une structure de base (6) et un cadre de support (4). Le levier (16) peut pivoter autour d'un point d'appui (30) et est soumis à l'action d'un ressort (28). Le point d'appui (30) est déplaçable par l'actuateur (32) le long d'un guide (34). Un tel déplacement non seulement fait varier la contrainte exercée par le ressort (28), mais également modifie le bras de moment (h) entre le ressort (28) et le point d'appui (30). Lorsque l'on soulève le cadre de support (4) à un niveau prédéterminé, le mécanisme s'adapte automatiquement à la charge sur ledit cadre de support afin d'assurer au système une fréquence naturelle constante, quelque soit le poids du patient transporté. | ||||||
| 122 | Motor ambulance bed with damping and variable inclination | EP88200073.0 | 1988-01-18 | EP0278547A3 | 1989-07-12 | Menna, Ezio |
The bed comprises a first lifting device consisting of a lever mechanism (20) arranged to raise one end (1ʹ) of the bed surface (1), and a second lifting device consisting of a cylinder-piston unit (11) provided with a damping and elastic reaction element (12) and arranged to raise the other end (1ʺ) of the bed surface (1); the two lifting devices act independently, so enabling the inclination of the bed surface to be adjusted in both directions; the bed is also of simple and economical construction and can be fitted to its transporting vehicle in a simple and rapid manner. |

® Das gefederte Teil (2) des Gestelles ist mittels eines Gestängeteiles (12) auf einem pneumatischen Federaggregat (10) abgestützt. Zur Blockierung der Federung kann das Gestängeteil mittels einer pneumatisch betätigten Bremse (17) festgestellt werden, welche das Gestängeteil (12) spannfutterartig umgreift. |

| 126 | Vibration damping supports | EP83305088 | 1983-09-02 | EP0102838A3 | 1985-03-06 | Black, Joseph; Foster, Mark Andrew; Luard, Nicholas Godfrey |
@ This invention relates to vibration damping supports and in particular to a suspension unit for a stretcher. The stretcher support unit comprises a rectangular base frame (10) on which is supported, by means of a resilient support mechanism, a stretcher frame or carrier (11). The support mechanism comprises a pair of cantilever arms (20) inclined upwards in opposite directions and each pivotally mounted at its lower end on the base frame (10). The movements of the cantilever arms (20) are controlled by respective gas-liquid suspension units (30), which are mounted between the base frame (10) and an extension arm (28) of each cantilever arm (20). The suspension units comprise, in one embodiment, a gas reservoir (70), a sealed liquid reservoir (71), a flexible diaphragm (72) forming one end of the liquid reservoir and an actuator piston (73). This construction serves to damp the movements of the cantilever arms (20) and hence the stretcher mounted on the carrier (11), and also enable the height of the carrier to be varied between a loading position and a position in which the stretcher rides. |

| 127 | Ambulance car | EP80200574 | 1980-06-16 | EP0021526A3 | 1981-08-12 | Hogeveen, Gerrit Jan |
An ambulance car provided with a stretcher carrier, which is supported by a spring system with respect to the carriage work, said spring system comprising at least one hydropneumatic spring element (18,19) a liquid filled part (20) of which is connected to a pump (23) and is separated by a membrane (24) from a part (25) filled with a pressurized gas. Preferably the stretcher carrier (1) is supported by two pivotable rods (2,3) each one of said rods being connected to a hinge lever (8) and (9) respectively, while each one of said hinge levers is connected to the liquid filled cylindrical part 620b) of a spring element (18,19) by means of a connecting rod (14) bearing a piston 617) at the end thereof. |
