Definitions
- the present invention relates to the general technical field of loading assistance devices, and more particularly that of stretcher loading assistance devices.
- the present invention relates more specifically to a device for aiding the loading of a stretcher on board a vehicle, said stretcher extending longitudinally between a first and a second end.
- Stretchers are commonly used for the evacuation of injured people, usually in a seated or lying position. To carry out this evacuation, rescuers very often have to place a stretcher loaded with an injured person inside a vehicle. It is particularly important that re-boarding of the stretcher loaded in this way takes place both in complete safety for the injured person, i.e. in relative comfort, with no loading error that could lead to the stretcher tipping over (and therefore the injured), and as quickly as possible, due for example to the state of medical emergency in which the injured person finds himself. The needs for security and speed of loading are most often contradictory.
- This need to quickly load the loaded stretcher can be reinforced in the context of a military operation, for example, during the evacuation of a wounded person from a combat zone, in which the protection of people (rescuers , soldiers, vehicle personnel, etc.) and property (vehicle, medical equipment, etc.) is not guaranteed.
- the rescuers first carry the loaded stretcher to the vehicle, then hoist it manually within the latter, generally on the interior floor of the said vehicle.
- This hoisting stage is both painful for the rescuers and uncomfortable and risky for the person on the stretcher.
- the arduousness for the rescuers is in particular reinforced by two factors: on the one hand, the sometimes considerable weight of the person and the stretcher (in particular when it is a question of transporting a wounded soldier with his equipment), and on the other hand the height of the interior floor of the vehicle relative to the ground.
- stretcher transport trolleys designed to roll to an ambulance in which the stretcher is transferred with the trolley.
- the cart has legs at the end of which are wheels.
- the trolley is usually foldable at its feet to enter the ambulance by boarding the stretcher.
- Such trolleys cannot, however, be implemented in the context of rough or difficult terrain, for example in the mountains or at sea. interior floor, boarding must also take place on substantially flat ground on which the trolley can roll easily (in a street for example).
- the objects assigned to the present invention therefore aim to remedy the various drawbacks listed above and to propose a new device for aiding the loading of a stretcher on board a vehicle, which, while being particularly robust, reliable and practical , only requires a reduced effort from the rescuers and/or operators implementing it.

- the invention relates, according to a first aspect illustrated in the figures, to a device for aiding the loading 1 of a stretcher 2 on board a vehicle.
- the loading aid device 1 is advantageously designed to help carry out the boarding of a stretcher 2 within said vehicle.
- Said stretcher 2 is preferably "loaded", that is to say say that it is designed and intended to support and allow the transport of a person, for example an injured person, an animal, and/or objects, for example medical or military equipment.
- the term “stretcher” encompasses the stretcher 2 as such, but also its possible load, whether human, animal, and/or material.
- the loading aid device 1 is also suitable for loading the stretcher 2 alone, that is to say unloaded.
- the vehicle is for example an automobile, a utility vehicle (truck, fire engine, etc.), an ambulance, an aircraft, a ship, etc.
- the vehicle is an aircraft, for example an ambulance aircraft.
- said vehicle is a helicopter, for example an ambulance helicopter.
- the vehicle is a military aircraft, for example a military helicopter or a military aircraft (for ambulance purposes for example).
- Said vehicle may have an interior floor which, according to a particular embodiment, is at a height, relative to the ground when the vehicle is placed on it, greater than 60 cm, preferably greater than 80 cm, more preferably greater than 100 cm or even greater than 120 cm.
- the loading aid device 1 of the invention makes this boarding easier for the rescuers and/or operators, but also more secure for the person, the animal or the material transported on the stretcher 2.
- the loading aid device 1 is preferably intended to be secured to said vehicle, for example via a support assembly 11 of the device 1 .
- said stretcher 2 extends longitudinally between a first and a second end 3, 4.
- the stretcher 2 is preferably designed to be grasped at the level of the first end 3 by one or more operators/rescuers, and at the level of the second end 4 by one or more other operators/rescuers.
- the first end 3 is preferably the one which must enter the vehicle first when loading the stretcher within the latter, while the second end 4 enters afterwards.
- An example of a stretcher 2 in accordance with the invention is illustrated in Figures 5 and 6.
- the stretcher 2 has, according to a particular embodiment, a substantially rectangular general shape, but it can have, according to other alternatives, a different general shape, for example a substantially ovoid, oval, triangular general shape, etc.
- said device 1 comprises at least one substantially elongated and tiltable guide means 5 between a substantially horizontal position and an inclined position.
- the device 1 is preferably designed so that said guide means 5 can be placed substantially horizontal (in a substantially horizontal position) then inclined, that is to say obliquely (nor vertically or horizontally), in an inclined position, and vice versa, going from oblique to horizontal.
- An example of guide means 5 in a substantially horizontal position is shown in Figures 1 and 2
- an example of guide means 5 in an inclined position is shown in Figures 3 to 6.
- Said guide means 5 advantageously extends along a direction of longitudinal extension L.
- the latter is preferably oriented substantially horizontally when said guide means 5 is in a substantially horizontal position, and oriented substantially obliquely when said guide means 5 is in position. inclined position.
- the direction of longitudinal extension L forms for example an angle of between 5 and 70° with the horizontal plane, preferably between 10 and 60°, more preferably between 15 and 50°.
- the guide means 5 preferably extends longitudinally, that is to say advantageously along said direction of longitudinal extension L, between a primary end 6 and a secondary end 7. In an inclined position, the primary end 6 is preferably located at an altitude higher than that of the secondary end 7.
- the inclination of said guide means 5 is made along a first axis of rotation A substantially perpendicular to said direction of longitudinal extension L.
- Loading aid device 1 is, according to a particular variant, designed so that the guide means 5 can pass from said substantially horizontal position and to said inclined position and vice versa by rotation about a substantially horizontal axis of rotation.
- said first axis of rotation A is preferably substantially horizontal, although other alternatives exist (it could possibly be oblique).
- Said guide means 5 preferably comprises a rail (as illustrated in the figures), a profile, and/or a guide post, but it may comprise any other substantially elongated shape which is suitable.
- the loading aid device further comprises at least a first support element 8 designed to receive said stretcher 2 towards said first end 3.
- Said first support element 8 is therefore advantageously designed to support and possibly be attached to at least a part of said stretcher 2, more precisely a part of said stretcher 2 located in the vicinity of said first end 3 (and preferably opposite said second end 4).
- Said first support element 8 is advantageously designed to come into mechanical connection with said stretcher 2 so as to remove at least one degree of freedom from the latter.
- Said first support element 8 may optionally be designed to come into mechanical connection with said stretcher 2 so as to remove at least one other degree of freedom from the latter, said first support element 8 then being designed to come into mechanical connection with said stretcher 2 so as to remove at least two degrees of freedom from the latter.
- Said first support element 8 is, according to a particular variant, designed to be attached to said stretcher 2, for example to the handles thereof (when said stretcher 2 has such handles).
- said first support element 8 is mounted in translation relative to said guide means 5 so that in an inclined position, said first support element 8 can pass from a high position to a low position.
- said device 1 is preferably designed so that said first support element 8 can pass from the high position to the low position, and vice versa, via a movement in translation, which movement in translation is advantageously carried out along said guide means 5
- the first support element 8 comprises for example a carriage designed to slide along said guide means 5 following a translational movement, preferably in a direction parallel to or coinciding with the direction of longitudinal extension L of the guide means 5, said carriage being designed to embark said stretcher 2 towards said first end 3.
- first support element 8 in the high position is illustrated in Figures 3 and 6, and an example of first support element 8 in the low position is illustrated in Figures 4 and 5, the high position preferably corresponds to a first altitude at which the first support element 8 is located, and the low position advantageously corresponds to a second altitude at which the first support element 8 is located, said second altitude being lower than said first altitude.
- the first support element 8 is preferably designed to pass from the high position to the low position, and vice versa, by performing a translational movement in a direction parallel to or coinciding with said direction of longitudinal extension L
- first support element 8 passes from the high position to the low position, it moves away from said primary end 6 and approaches said secondary end 7, and when the first support element 8 passes from the low position to the high position, it s moves away from said secondary end 7 and approaches said primary end 6.
- the first support element 8 is thus advantageously designed to, while it supports the stretcher 2 (or at least a part thereof), pass from the low position to the high position according to a translational movement in a direction parallel or coincident with the direction of longitudinal extension L of the guide means 5.
- this allows the stretcher 2 or a part thereof to pass from a lower altitude to a higher altitude by being supported by the first support element 8 instead of being supported manually by one or more rescuers/operators, thus considerably reducing the difficulty of boarding the stretcher for them.
- Said rescuers/operators only have to push (upward) said stretcher 2 and/or said first support element 8, from the lower altitude and/or from the low position to the higher altitude and/or the high position, said first support element 8 sliding for example from the low position to the high position along said guide means 5 while supporting said stretcher 2.
- the loading aid device 1 comprises at least one first return means 9 designed to exert a return force from the first support element 8 towards the high position when said first support element 8 is positioned in the low position and/or is located between the high and low positions.
- Said first return means 9 comprises for example at least one gas spring, a spring, and/or an elastic return element.
- a first return means 9 in the form of one or more gas struts is illustrated in Figure 1 (two jacks) and in Figure 2 (single jack), the size and positioning of this or these gas struts (and more generally of the first return means 9) which may vary.
- Said first return means 9 advantageously makes it possible to facilitate the passage of the first support element 8 from the low position to the high position, in particular when it receives said stretcher 2. Said first return means 9 therefore preferentially forms an assistance making it possible to facilitate the passage of the stretcher 2 or a part thereof received by the first support element 8 from a lower altitude to a higher altitude.
- the first return element 9 should advantageously not be too powerful, because it is preferably designed so that the descent (by translation) of the first support element 8 from the high position to the low position can be done manually, i.e. that is to say by operators/rescuers by simply pulling or pushing the first support element 8 downwards (and more precisely towards said secondary end 7) when the guide means 5 is in an inclined position.
- said first return means 9 is advantageously designed to exert said return force of the first support element 8 towards said primary end 6.
- Said first return means 9, which remains optional, is therefore preferably designed to drive said first support element 8 away from said secondary end 7.
- the loading aid device 1 comprises, according to a particular variant, a moving means designed to move the first support element 8 towards the high position when the latter is positioned in the low position and/or is located between the positions high and low.
- Said displacement means is therefore preferably designed to carry out the displacement of the first support element 8 towards said primary end 6.
- Said displacement means comprises for example a crank, as well as optionally a set of gears and/or a linked belt ( s) to said crank.
- Said movement means advantageously makes it possible to move the first support element 8 along the guide means 5.
- Said movement means is preferably designed to be actuated manually, but can alternatively be actuated electrically, pneumatically and/or hydraulically.
- the displacement means comprises the first return means 9 described above and/or the second return means described below, either alone or in combination with another means such as said crank (and optionally said set of gears and/or said belt).
- the loading aid device 1 comprises at least one second return means designed to exert a return force from the first support element 8 towards the low position when the said first support element 8 is positioned in position high and/or is located between the low and high positions.
- Said second return means comprises for example at least one gas spring, a spring, and/or an elastic return element. Said second return means thus exerts a return force opposite to the return force exerted by said first return means 9.
- Said first return means 9 advantageously makes it possible to facilitate the passage of the first support element 8 from the high position to the position low, in particular before it receives said stretcher 2, so as to reduce the effort required of the rescuers/operators when they seek to lower the first support element s from its high position to its low position.
- Said second return means therefore preferably forms an assistance enabling the passage of the first support element 8 from said high position to said low position to be facilitated.
- said second return means is advantageously designed to exert its return force from the first support element 8 towards said secondary end 7.
- Said second return means is therefore preferably designed to drive said first support element 8 away from said primary end 6.
- the return force exerted by the first return means 9 is greater than the return force exerted by the second return means.
- the first loading aid device 1 further comprises a second support element 10 designed to receive said stretcher 2 towards said second end 4.
- Said second support element 10 is therefore advantageously designed to support and possibly be attached to at least a part of said stretcher 2, more precisely a part of said stretcher 2 located in the vicinity of said second end 4 (and preferably opposite said first end 3).
- said second support element 10 is integral with said guide means 5.
- said second support element 10 is part of a different assembly than the guide means s.
- Said second support element 10 has for example a shape that is substantially similar and/or symmetrical to that of the first support element 8, as illustrated in the figures. Such a configuration makes the manufacture of the device 1 less expensive and its use simpler.
- said second support element 10 is, as shown in the figures, completely secured to said guide means 5, and therefore has no degree of freedom with respect to the latter.
- Such a configuration makes it possible to confer excellent robustness on the device 1, the second support element 10 being advantageously designed to support at least part, or even most of the weight of the stretcher 1 when the guide means 5 is in an inclined position, as shown in Figure 6.
- said second support element 10 is fixed to guide means 5 towards or at said secondary end 7, as illustrated in the figures.
- said second support element 10 forms all or part of said secondary end 7.
- said second support element 10 when said guide means 5 is in an inclined position, said second support element 10 is at an altitude which is lower than that of said first support element 8.
- said second support element 10 is advantageously (but not necessarily) at an altitude which is substantially similar to that of said first support element 8.
- said first support element 8 When said first support element 8 is in the low position, it is preferably closer to the second support element 10 than when it is in the high position.
- Said second support element 10 is advantageously designed to come into mechanical connection with said stretcher 2 so as to remove at least one degree of freedom from the latter.
- Said second support element 10 may optionally be designed to come into mechanical connection with said stretcher 2 so as to remove at least one other degree of freedom from the latter, said second support element 10 then being designed to come into mechanical connection with said stretcher 2 so as to remove at least two degrees of freedom from the latter.
- Said second support element 10 is, according to a particular variant, designed to be attached to said stretcher 2, for example to the handles thereof (when said stretcher 2 has such handles).
- the loading aid device 1 is preferably designed so that the first support element 8, when it is in the low position (figure 4), receives said stretcher 2 towards said first end 3 (figure 5), then that the first support element 8 passes into the high position with at least a part of the stretcher 2 embarked by the latter, the second support element 10 then receiving said stretcher 2 towards said second end 4, said stretcher 2 then being preferentially entirely supported by said first and second support elements 8, 10 ( Figure 6).
- said stretcher 2 is advantageously carried by said guide means 5 via said first and second support elements 8, 10, said first support element 8 being mounted in translation relative to said guide means 5, while said second support element 10 is preferably mounted fixed, completely integral with said guide means 5.
- the loading aid device 1 further comprises, as illustrated in the figures, at least one support assembly 11 intended to be secured to said vehicle, for example to the (interior) floor of said vehicle.
- said support assembly 11 can be fixed to an interior side wall of said vehicle, or to a part of the latter.
- Said support assembly 11 comprises for example a plate, said plate being according to a particular variant intended to be secured to the floor of the vehicle, more precisely against the latter, said plate therefore being intended to be positioned approximately horizontally.
- Said support assembly 11 can be secured to the vehicle, for example to the interior floor of the latter, by screwing, welding, clipping, blocking by rail (for example those commonly found on the floor of certain aircraft such as helicopters), etc. .
- Said support assembly 11 is also advantageously connected to guide means 5.
- said guide means 5 is mounted in translation relative to said support assembly 11 so that in a substantially horizontal position, said guide means 5 can pass from a retracted position (FIG. 1) in a deployed position (FIG. 2) in which it is farther from a proximal point 12 of said support assembly 11 than in said retracted position.
- Said proximal point 12 is advantageously intended to be positioned inside said vehicle.
- the guide means 5 In said retracted position, the guide means 5 is preferably positioned in whole or in part in the vehicle, and in said deployed position, said guide means 5 can be positioned in whole or in part outside the vehicle, the guide means 5 being optionally located further outside the vehicle in the deployed position than in the retracted position.
- the proximal point 12 can for example be a zone of the support assembly 11, for example a part of said plate and/or a portion of the support assembly above said plate.
- Said guide means 5 comprises for example a lower rail, preferably positioned opposite the support assembly 11 when the guide means 5 is in the retracted position, said lower rail making it possible to perform a translational movement to pass from one position to the other between the retracted position to the deployed position.
- the passage from one position to the other between said retracted and deployed positions is carried out according to a translational movement in a direction parallel to or coincident with said direction of longitudinal extension L.
- Said proximal point 12 is for example on or in line with said direction (of translation) parallel to or coincident with said direction of longitudinal extension L
- the loading aid device 1 further comprises locking means (not shown) designed to lock said guide means 5 in position when it is in said retracted position and/or in said deployed position.
- Said locking means is therefore preferably designed to block a degree of freedom at the less of said guide means 5 with respect to the support assembly 11 .
- said locking means is therefore advantageously designed to prevent the translation, for example in the horizontal plane and/or along the direction of longitudinal extension L, of said guide means 5 relative to the support assembly 11.
- the locking means is designed to be unlocked at will, for example manually by the rescuers/operators.
- the loading aid device 1 is designed so that, in a substantially horizontal position, it allows the displacement in translation, preferably substantially horizontal (and along the direction of longitudinal extension L), of said stretcher 2 from a first position (substantially horizontal) within the vehicle to at least a second position (substantially horizontal) at the within the vehicle, and vice versa, the second positioning advantageously making it possible to place at least a part of the stretcher 2 in a rear part of said vehicle, and more precisely an internal space at the rear of said vehicle with respect to the forward movement of this last.
- Said displacement in translation of the stretcher 2 is advantageously carried out in the direction in which the length of the stretcher 2 extends.
- the first positioning is preferably distinct and distant from the second positioning, the stretcher 2 not being located at same location of the internal space of the vehicle in each of said first and second positions.
- the second positioning corresponds to placing an individual on the stretcher 2 so that his legs are at least partly located in said rear part of the vehicle, which is for example the tail of an aircraft, and especially the tail of a helicopter.
- Such a configuration allows both to maximize the use of the restricted interior space of the helicopter (or other vehicle), but also for the rescuers/operators to more easily access the head and/or the trunk of the body. of the individual on the stretcher 2, the injuries being very often located at the level of these parts of the body.
- the first positioning of the stretcher 2 corresponds to the retracted position of the guide means 5 with the latter entirely within the vehicle, while the second positioning of the stretcher 2 corresponds to the deployed position of the guide means 5 with this last entirely within the vehicle (contrary to what we see in Figures 1 and 2, but the translational movement is substantially the same).
- the stretcher 2 in particular occupies a more "central" position within the internal space of the vehicle than in the second positioning, and therefore limits the movements of the rescuers/operators more than when it is in the second positioning, in which at least part of the stretcher 2 occupies the rear of the vehicle, which is frequently considered to be a "lost" space because it is not easily accessible by the crew or the rescuers/operators, in particular in the case of the tail of an aircraft.
- the loading aid device 1 is also advantageously designed to be able to block said stretcher 2 in said first positioning and/or second positioning, that is to say prevent said stretcher 2 from moving in translation from the first positioning to the second positioning and/or from the second positioning to the first positioning, for example using said locking means. This makes it possible to secure the stretcher 2 in the horizontal plane during its transport within the vehicle.
- said guide means 5 is rotatably mounted relative to said support assembly 10 along at least one primary axis of rotation V which is substantially vertical.
- said guide means 5 can be placed, by rotation along (at least) said primary axis of rotation V, in a first transport position (not shown), in which the direction of longitudinal extension L is preferably substantially parallel to or coincident with the direction of forward movement of said vehicle.
- the rotation of said guide means 5 relative to said support assembly 10 is advantageously achievable (and preferably only) when the guide means 5 is in a substantially horizontal position, and preferably in a retracted position.
- the primary axis of rotation V and the first axis of rotation A are preferably secant, and more preferably substantially orthogonal to each other.
- said guide means 5 is rotatably mounted relative to said support assembly 10 along at least one secondary axis of rotation S which is advantageously substantially vertical, said secondary axis of rotation S preferably being separate and distant from said axis of rotation primary V.
- Said secondary axis of rotation S passes for example through the proximal point 12.
- Said primary axis of rotation P and said secondary axis of rotation S are preferably substantially parallel to each other.
- the loading aid device 1 advantageously comprises, as illustrated in the figures, interconnection means between said guide means 5 and said support assembly 11.
- Said interconnection means comprises for example at least one, several or the all of the following:
- first hinge 14 preferably at said fourth end, providing a pivot connection between said spacer 13 and said guide means 5 along the first axis of rotation A,
- first and second hinges 14, 15 possibly being at least partly superimposed and/or merged as illustrated in the figures,
- a third hinge 16 preferably at said third end, providing a pivot connection between said spacer 13 and said support assembly 11 along the secondary axis of rotation S, said third hinge 16 therefore preferably being separate and distant from said first hinge 14 and/or of said second hinge 15, said proximal point 12 being for example formed by said third hinge 16 or a part thereof.
- Such a configuration, where the guide means 5 can rotate along two (separate) vertical axes (primary V and secondary S rotation axes) relative to the support assembly 11, advantageously makes it possible to optimize the positioning of the stretcher 2 at the inside the vehicle, when said stretcher 2 is supported by the loading aid device 1 preferably in a substantially horizontal position and in a retracted position.
- This makes it possible to optimize the internal space of the vehicle and/or to place the stretcher 2 in a practical position for the operators/rescuers, for example if they have to practice care for an injured person on the stretcher 2.
- said stretcher 2 comprises a receiving plate 17 as well as, towards said first end 3, two primary arms 18 protruding from said receiving tray 17.
- Said first support element 8 advantageously comprises at least two receiving means 19 each designed to receive one of said two primary arms 11.
- said stretcher 2 comprises, towards said first end 3, two secondary arms 20 projecting out of said reception plate 17.
- Said second support element 10 then advantageously comprises at least two reception means 21 each designed to receive one of said two secondary arms 20.
- Each arm 18, 20 advantageously forms a respective handle of said stretcher 2.
- Each receiving means 19, 21 comprises for example a recessed shape complementary to the arm 18, 20 that it is intended to receive.
- Each primary arm 18 is optionally in the extension and secured to one of said corresponding secondary arm 20 .
- each arm 18, 20 extends in a direction that is substantially parallel to or coincides with said direction of longitudinal extension L.
- Said arms 18, 20 preferably extend substantially in the extension of the receiving plate 17.
- one, several, or each of the reception means 19, 21 comprises a respective locking system designed to lock the corresponding arm 18, 20 in position, such a configuration making it possible in particular to secure the stretcher 2 (and therefore the injured individual on it) a once it is placed on the receiving means 19, 21.
- each blocking system can be locked and unlocked at will, for example manually by the rescuers/operators.
- the guide means 5 first passes from a transport position (not illustrated), in which the direction of longitudinal extension L is substantially parallel to or coincident with the direction of forward movement of said vehicle, at a preliminary loading position, as illustrated in FIG.
- the guide means 5 performs, for example, an overall rotation of 90° horizontally between the transport position and the preliminary loading position, which corresponds in practice to the retracted position and to the substantially horizontal position of the guide means 5, in figure 1 .
- the guide means 5 then passes from the retracted position, as shown in Figure 1, to the deployed position, as shown in Figure 2, by translation of said guide means 5 relative to the support assembly 11, the guide means 5 remains substantially at horizontal in extended and retracted positions.
- the guide means 5 can then pass from the substantially horizontal position (figure 2) to the inclined position (figure 3) by rotation along the first axis of rotation A, then the first support element 8 passes from the high position (FIG. 3) to the low position (FIG. 4) by translation, for example with the aid of manual pulling by one or more rescuers/operators, possibly assisted by a second means of recall.
- the stretcher 2 is then loaded onto the first support element 8 all the more easily since it is in the low position (FIG. 5).
- the primary arms 18 are placed on the receiving means 19 of the first support element 8, so as to at least partially block said stretcher 2 towards said first end 3 on said first support element 8 (removal of at least a degree of freedom of the stretcher 2).
- Said stretcher 2 is then pushed by the rescuer/operator(s), for example via said secondary arm 20, upwards (and towards the interior of the vehicle), and more precisely towards the primary end 6 of the guide means 5.
- the first support element 8 then rises along the guide means 5, performing an upward translation until it returns to the high position.
- the secondary arms 20 are placed on the receiving means 21 of the second support element 10, so as to at least partially block said stretcher 2 towards said second end 4 on the second support element 10 (removal of at least one degree of freedom of the stretcher 2), as illustrated in FIG. 6. It is then sufficient for the rescuers/operators to raise the guide means 5, for example by lifting it by the secondary end 7 or the said second support element 10, to to pass guide means 5, which is therefore responsible for said stretcher 2, from the inclined position to the substantially horizontal position, which would correspond to figure 2 to which it would be necessary to add the stretcher 2 of figure 6, said stretcher 2 being then horizontal.
- the guide means 5 then passes from the deployed position to the retracted position, which makes it possible to put at least part of the stretcher inside the vehicle, which would correspond to figure 1 to which the stretcher 2 would have to be added. of Figure 6.
- the guide means 5, loaded with the stretcher 2 passes from the preliminary loading position ( Figure 1 to which the stretcher of Figure 6 should be added) to the transport position (not shown) on the one hand by rotation (at 90° for example) of the spacer 13 relative to the support assembly 11 along the secondary axis of rotation S, and on the other hand by rotation (at 180° for example), of the spacer 13 relative to the guide means 5, which results in a rotation (at 90° for example) between the guide means 5 and the support assembly 11 by optimizing the internal space of the vehicle.
- the inclination of the guide means 5 and the translation between the high and low positions of the first support element 8 make it possible to facilitate the reboarding of the stretcher 2 by the device 1 and therefore by the vehicle, while the rotation of the guide means 5 horizontally (along the primary axes V and secondary S) and the passage of the latter in the retracted or deployed position make it possible to better manage the position of the stretcher 2 within the vehicle and therefore its position relative to the operators/rescuers who can, for example, assist an injured person on said stretcher 2.
- the stretcher 2 then passes from the first positioning to the second positioning by horizontal translation, in order to place part of the stretcher 2 and the individual (his legs for example) in the rear part of the internal space of the vehicle, such as the tail of a helicopter.
- the passage from the first positioning to the second positioning can be achieved by causing the guide means 5 to slide in translation relative to the support assembly 11 from the retracted position to the deployed position, the guide means 5 remaining this time entirely within the vehicle in both positions.
- the locking means is implemented in order to block the guide means 5 (which is therefore in the deployed position) to secure the stretcher and therefore in particular the injured individual embarked by the latter.
- the invention relates, according to a second aspect illustrated in Figures 5 and 6, to a loading system comprising at least one stretcher 2 and a loading aid device 1 of said stretcher 2 as described previously.
- the stretcher 2 and the loading aid device 1 are therefore advantageously as described above.
- the stretcher 2 of the loading system is therefore preferably designed to be received (by), and possibly secured, to the loading aid device 1 .
- the invention relates, according to a third aspect, to a vehicle equipped with a loading aid device 1 of stretcher 2 as described above.
- the vehicle, the loading aid device 1 and the stretcher 2 are therefore advantageously as described above.
- the vehicle and the loading assistance device 1 are for example secured to each other via the support assembly 11 attached to the interior floor of the vehicle.
- the loading aid device 1 is therefore advantageously designed to aid in the loading of said stretcher 2 on board said vehicle.
- the loading aid device 1 of the invention makes it possible to quickly, safely and conveniently load a stretcher 2 on board a vehicle, while minimizing the effort necessary for the rescuers/operators to carry out this loading
- the invention further relates to a device for aiding the loading 1 of a stretcher 2 to edge of a vehicle, said stretcher 2 extending longitudinally between a first and a second end 3, 4, said device 1 comprising at least:
- a guide means 5 substantially elongated and tiltable between a substantially horizontal position and an inclined position
- first support element 8 designed to receive said stretcher 2 towards said first end 3, said first support element 8 being mounted in translation relative to said guide means 5 so that in an inclined position, said first support element 8 can pass from a high position to a low position,
- a first biasing means 9 designed to exert a biasing force of the first support element 8 towards the high position when said first support element 8 is positioned in the low position and/or is located between the high and low positions.
- the invention finds its industrial application in the design, manufacture and use of aid devices for loading stretcher(s) on board vehicles, in particular military aircraft and/or ambulance aircraft.
- the invention also finds its industrial application in the design, manufacture and use of a loading system comprising such a loading aid device and a stretcher, as well as in the design, manufacture and use of a vehicle equipped with such a stretcher loading aid device.
