Definitions

  • the present invention relates to a device for automatic or manual opening of a safety equipment box door, intended in particular for boxes containing oxygen masks on board aircraft.
  • Such boxes are in fact provided on board airplanes with pressurized cockpits to provide each passenger with an oxygen mask in the event of an incident leading to a drop in the pressure prevailing in the cockpit.
  • the mask is contained in a special box which is located near the passenger seat and which is provided with a door which can be opened automatically or manually.
  • this box is equipped with a particularly reliable device making it possible to ensure the automatic or manual opening of the door and also making it possible then to ensure the closing and the maintenance in this closed position.
  • the present invention therefore relates to an automatic or manual device for opening a security equipment box door which offers increased reliability compared to the devices of the prior art.
  • the device essentially comprises a hook movable between a closed position where it keeps the door closed and an open position where it allows the door to be opened, as well as an unlocking plate which is normally recalled to a service position where it keeps the hook in the closed position and which is temporarily movable, either manually or automatically, to a retracting position where it recalls the hook in the open position.
  • the temporary and automatic movement of the unlocking plate towards its retracting position can be ensured by any known automatic actuation means. This is how, for example, electrical, electromagnetic, mechanical, electromechanical or pneumatic means can be used.
  • pneumatic means such as aneroide capsules.
  • aneroide capsules have the advantage of being able to automatically control the movement of the locking plate under the effect of a pressure drop in the passenger compartment of the aircraft and of not requiring electrical wiring.
  • the release plate can be connected directly or indirectly to the hook. However, it is preferable to provide an intermediate member of the lever type, in particular allowing manual reset of the device after use.
  • the device essentially comprises a pivoting hook which is designed to engage with a lug secured to the door and which is movable between a closed position and an open position; a main spring tending to return the hook to its open position; a pivoting locking lever, movable between a locking position where it retains the main spring to keep the hook in the closed position and an unlocked position which releases the main spring to bring the hook in the open position; a secondary spring tending to return the locking lever to its unlocked position and to return the hook to its closed position; and an unlocking plate which is normally returned to a service position where it is capable of retaining the locking lever in the locked position and which is temporarily movable, either manually or automatically, to a retracting position to release the lever and thus bring it into the unlocking position.
  • the hook and the lever are pivotally mounted about a common axis and the secondary spring is partially wound around this common axis and is supported between the hook and the lever.
  • the plate is movable in translation in a direction perpendicular to said common axis, the plate being closer to this common axis in the service position than in the retracting position.
  • This plate comprises a cup-shaped part which defines a bottom wall perpendicular to the direction of translation, as well as a first opposite wall and a second opposite wall which are attached to the bottom wall and which extend generally parallel to the direction of translation.
  • the first wall is a support wall for a retaining part of the lever and this wall support extends outside of the bowl by a ramp adapted to cooperate with one end of the retaining part, a manual actuator being connected to the bowl-shaped part.
  • the device shown in the figures! to 3 comprises a frame 10 which is intended to be fixed to a wall 12 of a box of safety equipment and which is provided with a pivoting hook 14 designed to engage with a lug 16 secured to a trigger guard 18 intended to be fixed on door 20 of the above-mentioned equipment box.
  • the frame 10 has several orifices 22 to allow it to be fixed to the wall 12 and, correspondingly, the trigger guard 18 is provided with orifices 24 allowing it to be fixed to the door 20.
  • the hook 14 is designed to pivot about an axis 26 between a closed position (shown in solid lines in FIG. 1) where the hook is engaged with the lug 16 and an open position (shown in broken lines on Figure 1) where the hook is no longer engaged with the lug 16.
  • the movement of the hook 14 between the two aforementioned positions is limited by a stop 28 integral with the frame 10 which is intended to cooperate with the hook itself in the open position and with a first extension 30 of the hook in the closed position.
  • the hook 14 is also provided with a second extension 32 which is located opposite the hook spout relative to the pivot axis 26.
  • the device further comprises a main spring 34 which tends to return the hook 14 to its open position.
  • the main spring 34 has two windings 36 concentric with the pivot axis 26 and an intermediate portion 38 which comes to bear on the second extension 32 above.
  • the two free ends 42 of the main spring 34 are folded, facing each other and inserted inside a sleeve 44 which comes to bear on the unlocking plate which will be described later.
  • the device also comprises a locking lever 46 which pivots around the above-mentioned axis 26 and which is movable between a locking position (shown in solid lines in FIG. 1) where it retains the main spring 34 to hold the hook 16 in position closing and an unlocking position (shown in broken lines in Figure 1) where it releases the main spring 34 to bring the hook in the open position.
  • a locking position shown in solid lines in FIG. 1 where it retains the main spring 34 to hold the hook 16 in position closing
  • an unlocking position shown in broken lines in Figure 1 where it releases the main spring 34 to bring the hook in the open position.
  • the locking lever 46 comprises a lever 48 which can be actuated manually to allow its displacement from the unlocking position to the locking position.
  • This lever also comprises a stop wall 43 which, in the locking position, is in axial alignment with the second extension 32 of the hook 14. As a result, in this position, the stop 49 blocks the action of the part 38 of the main spring 34 and prevents the latter from acting on the hook 14 to bring it back to the open position.
  • the locking lever 46 is also provided with a retaining part 50 which forms an acute angle with the lever 48 and which is intended to cooperate with the unlocking plate, as will be described later.
  • a stop 52 secured to the frame 10 is intended to cooperate with the locking lever and to limit the movement of this lever in its unlocking position.
  • a secondary spring 54 concentric with the axis 26 is provided to tend to return the locking lever 14 to its unlocking position and also to return the hook 14 to its closed position.
  • this secondary spring 54 comprises two windings 56 concentric with the axis 26, an intermediate part 58 which bears on the first extension of the hook 14 and two free parts 60 which bear behind the aforementioned retaining part 50.
  • the device also includes an unlocking plate 62 which is normally returned to a service position (shown in solid lines in FIG. 1) where it is capable of retaining the locking lever 46 in the locked position and which is temporarily movable, either manually or automatically, to a retracting position (shown in broken lines in Figure 1) to release the locking lever and thus bring it to the unlocking position.
  • a service position shown in solid lines in FIG. 1
  • a retracting position shown in broken lines in Figure 1
  • the plate 62 is movable in translation in a direction (represented by the arrow F) perpendicular to the common axis 26, the plate being. closer to this common axis in the service position than in the retracting position.
  • the plate 62 comprises a cup-shaped part 64 which defines a bottom wall 66 perpendicular to the direction of translation, as well as a first wall 68 and a second wall 70 opposite opposite which are attached to the bottom wall 66 and which generally extend parallel to the direction of translation.
  • the first wall 68 constitutes a bearing wall for the retaining part 50 of the locking lever 46 and this bearing wall extends outside the bowl 64 by a ramp 72 able to cooperate with one end 74 of the retaining part 50 and by a lever 76 which can be actuated manually.
  • the locking lever can be moved from the unlocking position to the locking position by acting on the lever 48 to reset the device. During this movement, the end 74 of the retaining part 50 slides along the ramp 72 and enters the bowl 64, the lever then returning to its locked position.
  • the second wall 70 of the plate 62 constitutes a support wall for the main spring 34, the sleeve 44 coming to cooperate with this support wall.
  • the plate 62 is connected to an automatic actuating member 78 which is provided with a cam 80 which cooperates with the bottom 66 of the bowl to move temporarily the plate 62 from the service position to the retracting position.
  • a return spring 82 is interposed between the bottom of the bowl and the member 78 to permanently return the plate to its service position.
  • the automatic actuating member 78 is intended to be controlled automatically and can therefore be constituted, for example, by an electrical, electromagnetic, mechanical, electromechanical, pneumatic, etc. member.
  • the member 78 is an electromagnetic member and the cam 80 is a cylindrical plunger core which has a planar end, perpendicular to the axis of the cylinder, and tapped so as to allow the fixing of the plate 72 directly on the cam 80 by means of a screw 84.
  • the return of the plate to its service position is effected by a spring 86 fixed under the cam 80 and whose return force is adjustable by a nut 88 at the base of the member 78 .
  • the shape of the cam 80 depends on the nature of the actuating member 78.
  • the cam would be completely different, since the plate would be attracted by a metal bellows.
  • This bellows could however have a flat at the end of connection with the plate and could therefore be fixed in the same way as the plunger core, thanks to the screw 84.
  • the device of the invention operates as follows. In the normal closed position, the various components of the device occupy the position shown in solid lines in FIG. 1.
  • the plate 62 is in its operating position where it blocks the lever 46 in its position. locking and where the latter blocks the action of the main spring 34, so that the hook 14 is held in the closed position.
  • the opening of the hook is triggered by the movement of the plate 62 from its operating position to its retracting position.
  • This triggering can be obtained in two ways, either by the actuating member 78 which exerts traction on the bottom 66 of the bowl, or by manual pressure on the lever 76 of the plate 62.
  • This movement has the effect of releasing the locking lever which, under the action of the secondary spring 54, moves towards the unlocking position shown in broken lines in FIG. 1. This movement also causes the release of the main spring 34 which can then act on the second extension 32 of the hook 14 and cause the displacement of this hook towards the open position.
  • the plate 62 is automatically returned to its operating position shown in solid lines in Figure 1.
  • the device To return the hook to its closed position, the device must be reset by manually acting on the lever 46 to return to the locked position. This rearming causes, as already indicated above, the sliding of the end 74 on the ramp 72 and its introduction inside the bowl 64.
  • main spring 34 it is particularly advantageous for the main spring 34 to bear on the wall 70 of the plate 62 because an axial symmetry of the tensile forces is obtained, since the opposite wall 68 is also subjected to the action. secondary spring 54.
  • the device of the invention is intended more particularly to equip boots with safety equipment on board airplanes with pressurized cockpit, the automatic actuation member of each device being connected to a central unit allowing automatic and simultaneous opening different devices in case of incidents.
  • each device can be operated manually, if necessary.
  • the invention is not limited to the embodiments specifically described and shown and also extends to other variants.
  • the manual actuating member connected to the bowl 64 instead of being constituted by a handle 76, could be constituted by a tool, such as a cylindrical rod, which would press on the bottom 66 of the bowl 64 thanks to a drilling in the door 20 and the trigger guard 18.
