Definitions
- the technical field of the invention is that of vehicles comprising an access hatch opening device, and in particular military vehicles.
- Access hatches for military vehicles have a ballistic protection that gives them a high mass of up to several tens of pounds.
- stress compensation devices allowing an operator to receive assistance during its handling hatches.
- the patent FR2943375 discloses a hatch opening device comprising a hatch articulated around a hinge axially solidly parallel to a horizontal wall of the vehicle which has an opening closable by the hatch.
- the device comprises a pair of torsion springs.
- the springs are arranged to assist the movement of the hatch each on half of the race of the hatch. They provide a raising effort of the hatch to a position close to the vertical and a braking force of the trap when it is placed horizontally.
- the invention proposes to solve the problem of difficulty in handling pivoting hatches on a glacis.
- the invention proposes a simplified manipulation device.
- the subject of the invention is a vehicle comprising a pivoting flap around an axis perpendicular to an inclined wall of the vehicle, a hatch stabilizable in position by the action of an elastic means which tends to position the hatch at the ends of the vehicle.
- the resilient means is secured to the hatch by its first end by a first hinge located at a distance from the axis, the elastic means being secured to the vehicle by its second end by means of a second hinge, axis and joints being positioned to be aligned when the center of gravity of the hatch is located in a vertical plane at the xe pivoting of the hatch, the elastic means then producing its maximum effort.
- the axis is located substantially above the hatch.
- the elastic means comprises a tension spring.
- the resilient means comprises a jack comprising a stack of compressible elastic washers.
- a vehicle 1 has a glaze 2 inclined at its front portion AV.
- the glaze 2 is formed by an inclined wall and it comprises a hatch 3 closing an opening 4 made in the glaze 2 (opening visible to the figure 3 ).
- a pivot axis 5 perpendicular to the glazing 2 and located substantially above the hatch 3 allows the hatch 3 to pivot parallel to the glaze 2 about said axis 5.
- the stroke of the hatch 3 is determined by two extreme positions, a first visible to the figure 1 where the opening 4 of the glaze 2 is completely closed and a second visible at the figure 3 where the opening 4 is completely clear.
- These two positions are so-called stable positions, that is to say that they are positions to which the hatch 3 is brought to replace in a privileged manner through means described below.
- a third intermediate position in the previous positions corresponds to the position occupied by the hatch 3 when the center of gravity G of the latter is situated in a plane vertical axis passing through the axis 5.
- the hatch would naturally be required to occupy this intermediate position by the effect of the joint gravity to the pendulum structure formed by hatch 3 around its axis 5.
- the vehicle comprises a device 10 for compensating the weight of the hatch 3 which comprises an elastic means 6 comprising a tension spring 6 with non-contiguous spirals.
- a first end 6b of the elastic means 6 having a first hinge (not shown) is integral with a portion of the hatch 3 located at a distance from the axis 5, between the center of gravity G and the pivot axis 5.
- the second end is positioned to provide a permanent tension of the spring 6 regardless of the position of the hatch 3.
- the weight P designates the component of the gravitational force of the mass of the hatch 3 projected in the plane of the glaze 2.
- the spring 6 has a length L1 and its tension exerts a force of which at least one of the components F tends to oppose the weight of the hatch 3, thus aiming to maintain the hatch 3 in the closed position of the opening 4.
- the spring 6 will exert a force whose component F in the plane of the glaze will be greater than the weight of the hatch 3 (component in this same plane), which will have the effect of keeping it on the opening 4, or lower, which will have the effect of slowing the hatch 3 in its descent under the effect of weight.
- an operator rotates the hatch 3 downwards by additional unspecified means (crank handle or auxiliary motor for example) thus exerting an additional effort in addition to the weight of the hatch 3 or slowing down the hatch 3 in its descent according to the choice of stiffness described above.
- the joints 6a and 6b of the elastic means 6 are aligned with the axis 5. It will be noted that the weight and the vertical component of the tension of the spring are also aligned.
- the hatch is then in an unstable position. Continuing the pivoting movement of the hatch 3 to reach the position shown in FIG. figure 3 , the center of gravity G of the hatch 3 passes the unstable position.
- the component F in the glazing plane of the force of the spring 6 then decreases gradually but exerting a proper pivoting torque to raise the hatch (or facilitate the recovery with the help provided by the operator).
- the opening 4 is completely disengaged and the spring 6 is again at its length L1, with a minimum applied force still exerting a component in the plane of the glaze of its tensile force opposed to the weight of the hatch.
- the position of the hatch when the opening is completely clear can also be asymmetrical with respect to the position when the opening is closed. In such a case, the length of the spring will be greater than the one he has when the hatch is closed. The effort provided will be greater but with a lower lever arm which will allow it to compensate for the moment due to the weight of the hatch in this position.
- the elastic means of the device 10 for compensating the weight of the hatch 3 may comprise a jack 6 comprising a stack of elastic conical washers 6c mounted head to tail and providing a force once compressed.
- a first end 6b of the jack 6 comprises a first hinge 6b connecting the jack 6 to the hatch 3 by means of a lever arm 3a, integral with the hatch 3, and one end of which is positioned at the axis 5 and the other end carries the hinge 6b.
- the lever arm 3a thus positions the hinge 6b at a distance from the axis 5.
- the angular position of the lever arm 3a is chosen so that when the center of gravity G of the hatch 3 is in the vertical plane V passing through the axis 5, the first and the second articulation 6b and 6a are aligned (in the direction D passing through the axis 5), thus forming an unstable position for the lever arm 3a.
- the stroke of the cylinder 6 will be chosen long enough for the cylinder 6 to exert a further effort to stabilize the hatch 4 on the extreme travel positions of the hatch 3.
- the figure 5 represents a view of the vehicle weight compensation device 10 according to the invention, and according to a third embodiment, as it can be seen by an operator in the vehicle.
- the pivot axis 5 of the hatch is fixed to the internal face 2a of the glazing, perpendicular to it and in the vicinity of the opening 4.
- the axis 5 comprises an electric motor 11 intended to rotate the hatch 3 around of the axis 5.
- the elastic means 6 is secured to the axis by a first hinge 6b and is integral with the glaze 2 by its second hinge 6a by means of a fastening stud 12.
- the invention thus makes it possible to compensate the weight of a hatch mounted on an inclined wall which facilitates the handling of the hatch. In addition, it uses only a single elastic means which simplifies the compensation device.

Description
Le domaine technique de l'invention est celui des véhicules comportant un dispositif d'ouverture de trappe d'accès, et en particulier les véhicules militaires.The technical field of the invention is that of vehicles comprising an access hatch opening device, and in particular military vehicles.
Les trappes d'accès pour véhicules militaires comportent une protection balistique qui leur confère une masse élevée pouvant aller jusqu'à plusieurs dizaines de kilos. Afin de rendre la manipulation de ces trappes aisée tant en ouverture qu'en fermeture, il est fait appel à des dispositifs de compensation d'effort permettant à un opérateur de bénéficier d'une assistance durant ses manipulations de trappe.Access hatches for military vehicles have a ballistic protection that gives them a high mass of up to several tens of pounds. In order to make the handling of these hatches easy both opening and closing, it is resorted to stress compensation devices allowing an operator to receive assistance during its handling hatches.
Le brevet
Le dispositif comporte une paire de ressorts de torsion. Les ressorts sont disposés de manière à assister le mouvement de la trappe chacun sur une moitié de la course de la trappe. Ils fournissent un effort de relèvement de la trappe jusqu'à une position proche de la verticale et un effort de freinage de la trappe lors de sa mise à l'horizontale.The device comprises a pair of torsion springs. The springs are arranged to assist the movement of the hatch each on half of the race of the hatch. They provide a raising effort of the hatch to a position close to the vertical and a braking force of the trap when it is placed horizontally.
Cependant, pour une ouverture située sur un glacis et placée par exemple sous une tourelle, un tel dispositif de manipulation n'est pas adapté car il risque d'y avoir une interférence de la trappe avec d'éventuels éléments situés au-dessus de la trappe, telle une tourelle.However, for an opening located on a glaze and placed for example under a turret, such a handling device is not suitable because there is a risk of interference of the hatch with possible elements located above the hatch, like a turret.
Ainsi, l'invention se propose de résoudre le problème de difficulté de manipulation de trappes pivotantes sur un glacis. Avantageusement l'invention propose un dispositif de manipulation simplifié.Thus, the invention proposes to solve the problem of difficulty in handling pivoting hatches on a glacis. Advantageously, the invention proposes a simplified manipulation device.
Ainsi, l'invention a pour objet un véhicule comportant une trappe pivotante autour d'un axe perpendiculaire à une paroi inclinée du véhicule, trappe stabilisable en position par l'action d'un moyen élastique qui tend à positionner la trappe aux extrémités de la course de pivotement de ladite trappe en contrant tout ou partie du poids de la trappe, le positionnement de la trappe sur une première extrémité obturant une ouverture de la paroi et le positionnement de la trappe sur une seconde extrémité dégageant l'ouverture de la paroi, véhicule caractérisé en ce que le moyen élastique est solidaire de la trappe par sa première extrémité grâce à une première articulation située à distance de l'axe, le moyen élastique étant solidaire du véhicule par sa seconde extrémité au moyen d'une seconde articulation, l'axe et les articulations étant positionnés de façon à être alignés lorsque le centre de gravité de la trappe est situé dans un plan vertical à l'axe de pivotement de la trappe, le moyen élastique produisant alors son effort maximal.Thus, the subject of the invention is a vehicle comprising a pivoting flap around an axis perpendicular to an inclined wall of the vehicle, a hatch stabilizable in position by the action of an elastic means which tends to position the hatch at the ends of the vehicle. pivoting stroke of said flap by controlling all or part of the weight of the flap, the positioning of the flap on a first end closing an opening of the wall and the positioning of the flap on a second end clearing the opening of the wall, characterized in that the resilient means is secured to the hatch by its first end by a first hinge located at a distance from the axis, the elastic means being secured to the vehicle by its second end by means of a second hinge, axis and joints being positioned to be aligned when the center of gravity of the hatch is located in a vertical plane at the xe pivoting of the hatch, the elastic means then producing its maximum effort.
Avantageusement, l'axe se situe sensiblement au-dessus de la trappe.Advantageously, the axis is located substantially above the hatch.
Avantageusement, le moyen élastique comporte un ressort de traction.Advantageously, the elastic means comprises a tension spring.

Selon la
Un axe de pivotement 5 perpendiculaire au glacis 2 et situé sensiblement au-dessus de la trappe 3 permet à la trappe 3 de pivoter parallèlement au glacis 2, autour dudit axe 5. La course de la trappe 3 est déterminée par deux positions extrêmes, une première visible à la
Ces deux positions sont des positions dites stables, c'est-à-dire que ce sont des positions vers lesquelles la trappe 3 est amenée à se replacer de manière privilégiée grâce à des moyens décris plus loin.These two positions are so-called stable positions, that is to say that they are positions to which the
Une troisième position intermédiaire aux positions précédentes, dite position instable et visible à la
Le véhicule comprend un dispositif 10 de compensation du poids de la trappe 3 qui comporte un moyen élastique 6 comportant un ressort de traction 6 à spirales non jointives. Une première extrémité 6b du moyen élastique 6 comportant une première articulation (non représentée) est solidaire d'une partie de la trappe 3 située à distance de l'axe 5, entre le centre de gravité G et l'axe 5 de pivotement.The vehicle comprises a
Une seconde extrémité 6a du moyen élastique 6, comportant une seconde articulation (non représentée), est solidaire du glacis 2 en un point situé dans un plan vertical V passant par l'axe 5. La seconde extrémité est positionnée pour procurer une tension permanente du ressort 6 quelle que soit la position de la trappe 3. Pour plus de commodité de description dans la suite du texte le poids P désigne la composante de l'effort gravitationnel de la masse de la trappe 3 projetée dans le plan du glacis 2.A
Ainsi, comme visible à la
Pour ouvrir la trappe 4, un opérateur (non représenté) fait pivoter la trappe 3 vers le bas par des moyens additionnels non décris (manivelle, poignée ou moteur auxiliaire par exemple) exerçant ainsi un effort supplémentaire s'ajoutant au poids de la trappe 3 ou bien ralentissant la trappe 3 dans sa descente selon le choix de raideur exposé précédemment.To open the
Le pivotement vers le bas de la trappe 3 provoque l'allongement progressif du ressort 6 jusqu'à ce que la trappe 3 rejoigne la position illustrée à la
Les articulations 6a et 6b du moyen élastique 6 sont alignées avec l'axe 5. On notera que le poids et la composante verticale de tension du ressort sont également alignés. La trappe est alors dans une position instable. En continuant le mouvement de pivotement de la trappe 3 pour rejoindre la position représentée à la
Une fois la position de la
Selon un autre mode de réalisation, illustré à la
Une première extrémité 6b du vérin 6 comporte une première articulation 6b reliant le vérin 6 à la trappe 3 au moyen d'un bras de levier 3a, solidaire de la trappe 3, et dont une extrémité est positionnée au niveau de l'axe 5 et l'autre extrémité porte l'articulation 6b.A
Le bras de levier 3a positionne ainsi l'articulation 6b à distance de l'axe 5. La position angulaire du bras de levier 3a est choisie de manière à ce que lorsque le centre de gravité G de la trappe 3 est dans le plan vertical V passant par l'axe 5, la première et la seconde articulation 6b et 6a sont alignées (suivant la direction D passant par l'axe 5), formant ainsi une position instable pour le bras de levier 3a. La course du vérin 6 sera choisie suffisamment longue pour que le vérin 6 exerce encore un effort visant à stabiliser la trappe 4 sur les positions de courses extrêmes de la trappe 3.The

Ainsi, l'opérateur voit la face interne 2a du glacis 2 dans laquelle l'ouverture 4, partiellement ouverte, permet de voir à l'extérieur du véhicule, le restant de l'ouverture 4 étant partiellement obturé par la trappe 3 (dont la face inférieure est ombrée par des hachures). L'axe de pivotement 5 de la trappe est fixé à la face interne 2a du glacis, perpendiculairement à celui-ci et au voisinage de l'ouverture 4. L'axe 5 comporte un moteur électrique 11 destiné à faire pivoter la trappe 3 autour de l'axe 5. Le moyen élastique 6 est solidaire de l'axe par une première articulation 6b et est solidaire du glacis 2 par sa seconde articulation 6a grâce à un plot de fixation 12.Thus, the operator sees the
L'invention permet ainsi de compenser le poids d'une trappe montée sur une paroi inclinée ce qui facilite les manipulations de la trappe. En outre, il n'est fait appel qu'à un unique moyen élastique ce qui simplifie le dispositif de compensation.The invention thus makes it possible to compensate the weight of a hatch mounted on an inclined wall which facilitates the handling of the hatch. In addition, it uses only a single elastic means which simplifies the compensation device.
