EP1666013A1 - Variable geometry stretcher which is helicopter liftable, floatable, in particular for the recovery of persons - Google Patents

Abstract

The stretcher has a metallic frame (1) supporting a telescopic plate (2), and including a sheet metal (6) and telescopic tubes (3) that assure variability of dimensions of the stretcher in length and width. The stretcher is covered by a covering (4) in lower part and a hood (5) mounted on slides (8) in upper part. Gripping handles (7) situated in lower part of the stretcher are adapted to stowing systems used onboard a transport unit.

Description

The present invention relates to a stretcher with variable geometry, helicopter, floating intended in particular for the recovery of people on land or at sea, comprising a frame supporting a plate and covered with a covering at the bottom and a hood at the top.

The existing stretchers are of variable dimensions and therefore can not adapt to different sizes of individuals.

On the other hand, these stretchers represent a large footprint.

The present invention aims to remedy these drawbacks and to do this, it relates to a stretcher of the aforementioned type which is essentially characterized in that its dimensions are variable in length and width to accommodate the size of the individual to carry.

Moreover, by its configuration this stretcher can be stored in its smallest dimensions.

According to a particular embodiment of the invention, the frame may be metallic and the plate that the person transported is still based on a rigid plane.

In addition, the metal frame makes the stretcher helvile regardless of its dimensions.

According to another characteristic of the invention, the stretcher can be stowed at stowage points of a transport means that can be an aircraft, a land vehicle or a ship.

According to yet another aspect of the invention, the stretcher can be floating by its configuration and the materials that compose it.

• la Figure 1 est une vue de la civière, « capot fermé »,« position réduite »,
• la Figure 2 est une vue de la civière, « capot ouvert », «position en extension »,
• la Figure 3 est une vue de la civière, « capot complètement ouvert » pour installer une personne sur la plaque.

An embodiment of the invention is hereinafter described by way of example with reference to the accompanying drawings in which:

• Figure 1 is a view of the stretcher, "closed hood", "reduced position",
• Figure 2 is a view of the stretcher, "open hood", "extended position",
• Figure 3 is a view of the stretcher, "completely open hood" to install a person on the plate.

The stretcher shown in Figures 1, 2 and 3 consists mainly of a metal frame (1) supporting a plate (2) telescopic length and width may be composite material on which rests the person collected by the rescuers.

The metal frame (1) consists essentially of telescopic tubes (3) which ensure the variability of the dimensions of the assembly in length and width.

The telescopic tubes (3) are lockable according to the desired length and width by means of locking devices which can be for example pins (9).

The variable geometry of the stretcher makes it possible to adapt to different sizes of individuals that can be children and thus ensures better safety and comfort during the rescue.

The stretcher is covered with a covering (4) telescopic bottom and a cover (5), which can be composed of several parts, mounted on slides (8) in the upper part. The hood is locked by means of quick closures. The covering (4) and the hood (5) protect the transported individual from possible shocks or weather or external aggressions that may occur during the rescue.

The metal frame (1) is also composed of sheets (6) that allow the hoist of the stretcher, regardless of its size, especially during salvage operation at sea or in perilous environment not accessible to land vehicles.

The set of tubes, sheets and plate ensures a perfect rigidity of the stretcher necessary for the transport of the individual and the safety of the hoist operations.

The gripping handles (7) located in the lower part allow the maneuverability of the assembly especially during the maneuvering boarding the stretcher aboard an aircraft, a land vehicle or a ship.

In order to avoid any problems resulting from violent accelerations / decelerations that may occur in a means of ground or air transport, the gripping handles are adapted to the securing systems used on the means of transport, aircraft, land vehicles or ships.

The stretcher may also be stowed in the rails of the aircraft or transport vehicle by means of a device for attaching equipment which is the subject of the

French Patent No. 0202964 and European Patent No. 03290541.6 or by means of the mobile stretcher attachment system which is the subject of French Patent No. 0109244 and European Patent No. 02293217.2 filed by the same inventor.

According to another characteristic of the invention, the stretcher is floating. The buoyancy of the stretcher is obtained from the materials that compose it and from the difference of masses. This buoyancy allows the person being rescued to have the airways cleared as part of a rescue at sea or in deep water.

Such a stretcher is a very convenient job for rescuers while providing increased security for the person transported.
