Definitions

  • the present invention relates to door locking systems and has specific reference to a door locking device adapted to be actuated either automatically, for example electrically or through pressure-fluid means, or mechanically by manual means notably in case of emergency.
  • the door locking device is characterized in that it comprises a guiding sleeve disposed within the locker or like box and having slidably mounted therein a piston responsive to an electromagnet or a fluid pressure so as to actuate with its lateral surface at least one lateral locking member movable in said. locker and adapted to coact with a retaining member rigid with the door so as to lock or release this door according as said piston is in its front or back position in said sleeve.
  • the piston is advantageously actuated in a direction opposite to said door to permit the manual opening thereof by exerting a pressure against the piston through a small aperture formed in the door or through the gap or slit formed or left between the door and its frame, for instance by using a special rod kept by the personnel (airhostess, steward, etc.), either for an emergency opening, in case of failure of the automatic control system, or for service maintenance requirements.
  • said piston engages a recess formed in the internal surface of the door and the lateral locking member is pushed radially outwards by the lateral surface of the piston so as to engage an internal cavity of said recess and thus provide the requisite locking action, the door being released by causing the reverse movement of said locking member during the controlled backward stroke of the piston.
  • the internal surface of the door carries an oliveshaped stud extending coaxially with the locking piston and adapted to engage a retaining mechanism comprising a pawl fulcrumed about a pivot pin parallel to the door and normally urged in its closing direction by the adjacent piston end, in the piston position nearest to said olive-shaped stud, the backward movement of said piston causing said pawl to release the stud and thus permit the door opening movement.
  • a retaining mechanism comprising a pawl fulcrumed about a pivot pin parallel to the door and normally urged in its closing direction by the adjacent piston end, in the piston position nearest to said olive-shaped stud, the backward movement of said piston causing said pawl to release the stud and thus permit the door opening movement.
  • Said olive-shaped stud may be formed with an axial through hole for receiving a rod extending through said door and stud assembly, and adapted to push the piston in case of emergency by a manual opening manoeuver.
  • the ingress of the last-named. axial through hole' may be closed by a shutter-forming element for normally preventing the insertion of foreign Y bodies into said hole.
  • the piston movement may be obtained using a bent rod introduced through the slit normally formed between the door and its frame on the side opposite to the door hinge.
  • the device according to this invention may be designed with a view to resort to modern industrial-processes for making light-weight parts thereof, such as moulded plastic pieces.
  • FIG. 1 is an axial section showing a first form of embodiment of the locking device of this invention
  • FIG. 2 is a similar section showing one portion of the device modified according to another form of embodiment of the invention
  • FIG. 3 is a fragmentary cross-sectional view of the locker, showing the engagement of a curved rod for unlocking the door
  • FIG. 4 is a similar section showing the device brought to its release or unlocking position by pushing said curved rod
  • FIG. 5 is an axial section showing another form of embodiment of the device incorporating an oliveshaped retaining member
  • FIG. 6 is an end view of the support of the device shown in FIG. 5
  • FIG. 7 is a front view of the door illustrated in FIGS. 5 and 6, showing the shutter or tamper-proof seal of the passage formed through said olive-shaped member, and
  • FIG. 8 shows amodified form of embodiment contemplated for an emergency actuation of the device by means of a rod introduced into the slit between the door and its frame.
  • the reference numeral 1 designates a fixed part of the locker which comprises a tapped hole 2 permitting the mounting and adjustment of the fixed support 3 through a screw 4 revolving on the trunnion 5 of the fixed support.
  • This fixed support 3 constitutes the external body of a control electromagnet and encloses a coil 6 having its supply conductors 7 disposed in a lateral notch 8 of the fixed support 3 and inserted in an electrical control circuit comprising for example a current source and an electric switch adapted to close automatically under the control of an aneroid capsule or bellows detecting a predetermined reduction in the pressure of the internal atmosphere of the aircraft, in case the locker is used for enclosing an oxygen mask.
  • the electric circuit may be controlled in any other suitable manner consistent with the specific equipment to be released for use.
  • the fixed support 3 carries a guiding sleeve 9 slidably engaged by a piston 10 constituting the core of the electromagnet which is constantly urged outwards by a relatively weak spring 11 interposed between a shoulder 12 of said support 3 and another shoulder 13 formed on the piston head.
  • the piston end or head comprises an extension 14 of reduced diameter beyond a larger portion consisting of a hardened portion 15 adapted to engage a circular set of locking balls 16 received in lateral apertures 17 formed in said sleeve 9 so as to project outwards when the ring 15 is coplanar with said balls (i.e., external or inoperative position of the piston, as shown in FIG. 1).
  • sleeve 9 in the closed locker position, engages a recess 18 formed on the inner surface of the door 19 and the open end 20 of this recess is narrowed so that the balls can clear this end 20 only when they recede towards the piston axis as permitted when the piston 10 is attracted by and moved towards the electromagnet coil 6.
  • a small aperture 21 is formed through the door 19, coaxially to said recess 18, so that the authorized personnel can introduce into this aperture 21 a rod permitting the manual actuation of the device by pushing back against the force of said weak spring 11 for unlocking the device and opening the door.
  • the balls 16 constitute the locking members of the device of this invention.
  • this arrangement should not be construed as limiting the invention since other locking members may be contemplated in lieu of said balls, for example in the form of elements having a different configuration and mode of action, as exemplified in FIG. 2 showing in axial section the external portion of the electromechanical control means of this modified form of embodiment.
  • the piston 10 constituting the electromagnet core is similar to the piston of FIG. 1 and the corresponding parts are designated by the same reference numerals in either case.
  • the sleeve 9 is also formed with lateral cavities 17 but the locking members, also disposed circularly as in the preceding example, consist in this construction of bent lugs 22 connected to the rear end of sleeve 9 by spring blades 23.
  • the lugs 22 are allowed to move inwards and thus permit the opening of door 19.
  • the device comprising a locking piston carried by the fixed portion of the locker and internally thereof may be substantially similar to the above-described device, for example with reference to FIG. 1.
  • the recess 18 engaged by the sleeve 9 and piston 10 is mounted on the door 19 along its opening edge opposite the hinged edge, a slit being normally left or formed between this opening edge and the fixed frame 24 of the door.
  • a lateral opening 25 extending towards the door beyond the end 14 of piston 10 in the forward position thereof is formed to permit the insertion, through the slit formed between the door and its frame and also through this opening 25, of a curved rod 26 adapted to project with its end between the piston end 14 and the door 19, as illustrated in FIG. 3.
  • the door is formed with an internal ledge 27 also formed with a suitable opening 28 permitting the passage of said curved rod 26.
  • FIG. 4 shows the backward position of piston 10 which permits of opening the door 19.
  • This invention is also concerned with the special tool consisting of a curved rod adapted to be introduced between the locking piston and the door through the slit left or formed between the door and its frame on the side opposite to the door hinge.
  • FIG. 5 thereference numeral 101 designates the locker to be closed and 102 is the door hinged at 103 and adapted to open instantaneously either by gravity 01 through the action of an opening spring (not shown).
  • an oliveshaped stud 104 mounted to the inner surface of this door is an oliveshaped stud 104 having its axis perpendicular to the door main surface this stud 104 is formed with a base flange retained in a socket 105 secured to the door. tween the door and the stud flange a resilient washer 106 is disposed to permit a slight oscillation of the 01- ive-shaped stud 104 and therefore an improved locking engagement between this stud and a retaining pawl to be described presently.
  • the olive-shaped stud 104 has an axial hole 107 formed therein, this hole registering with the hole of washer 106 and also with a corresponding hole 108 formed through the door 102.
  • the fixed element of the structure to which the door 102 is hingedly mounted carries the locking device proper.
  • This device comprises in this example an electromagnet and a plunger core.
  • the electromagnet con sists of a winding 109 housed in a cage 110 overlying a base plate 111 in a support-forming protection case comprising advantageously a pair of shells 112, 113 assembled by means of bolts 114.
  • the plunger core 115 is coaxial with the olive-shaped stud 104 and carries a retaining circlip or spring ring 116 limiting the stroke of the plunger core by abutting against a shoulder of said case 112, 113 this plunger core 115 is normally urged to its lower position, as seen in the drawing, by a coil compression spring 117 inserted between the base plate 111 and circlip 116, but it is adapted to rise while compressing the spring 117 when a suitable voltage is fed to the terminals of winding 109 through energizing conductors (not shown).
  • plunger core 115 In the lower position the lower end of plunger core 115 prevents the oscillation of a latch pawl 118 fulcrumed about a horizontal pivot pin 119 and adapted to wedge with one end or arm one side of the olive-shaped stud 104, the other side of stud 104 engaging the inner wall of case 112, 113, whereby the olive-shaped stud 104 is retained in the position to close the door 102.
  • a spring 120 cons'tantly urges the pawl 118 to its door-closing position.
  • this opening can nevertheless be obtained by introducing a thin metal rod through the door hole 108 and axial passage 107 of the olive-shaped stud 104, the thrust produced with this rod causing the plunger core 115 to move upwards and thus permits the rocking of pawl 118 and the opening of the door 102.
  • This thrust exerted on the plunger core 115 also permits, before the door closing, the oscillation of pawl 118 to re-introduce the stud 104 into the locking device.
  • the current necessary for opening the lockers may be fed automatically, if desired, in case of undesired or accidental pressure drop in the passenger compartment, by using a suitable or known manometric device therefor.
  • the emergency opening device is of particular or unusual design to avoid any untimely actuation of the device by a passenger.
  • the door must be opened by an air hostess or steward conversant with the mode of operation of the device. For the same reasons, the door cannot be reclosed unless the same tool is resorted to, so that the qualified personnel can check the proper disposition of the contents of a locker before closing same.
  • all the component elements thereof except of course the winding 109, the magnetic circuit and the springs, may be moulded from suitable plastic material.
  • a pivoting shutter 123 disposed against the inner surface of door 102.
  • This shutter 123 is pivoted to a small pin 124 and extends through a slot formed in the lateral ledge of the door so as to project externally with a bent lug 125 movable in the gap 126 formed or left between the door 102 and its frame 127.
  • This shutter 123 may consist for example of a lug formed beneath the olive-shaped stud 104 with a wider portion 128 in which a hole 129 is formed. In the normal position (lower or dash-line position in FIG.
  • the use of a single pawl such as 119 may be replaced by the use of two or three similar pawls disposed around the olive-shaped stud 104.
  • the locking piston 115 may if desired be actuated by means other than an electromagnetic device; thus, notably in the specific application concerning oxygen mask lockers on boards airliners, this piston could be actuated directly by a manometric capsule or bellows responsive to any abnormal reduction in the atmospheric pressure in the passenger compartment.
  • the locking device is applicable to various equipments, whenever the opening of a door is to be controlled automatically, or remote-controlled, by using electric current or fluid pressure.
  • the reference numeral 102 designates similarly the door, 105 being the socket retaining the base flange of the olive-shaped stud 10 i, and 113 the case portion enclosing the locking mechanism which may be similar to the one shown in section in FIG. 5.
  • This case is disposed behind the opening edge of the door which is opposite to the hinge 130 shown in FIG. 8, and carries laterally towards the door frame 131 an L-sectioned member 132 adapted to slide slightly in the direction of the axis of locking piston 1 15, this member 132 being guided by a screw 133 extending through an elongated aperture formed in this member and engaging a tapped hole formed in the case of the locking mechanism.
  • the member 132 comprises a bent lug 134 registering with the piston end, adapted to be pushed by means of a slightly curved rod 135 inserted through the slit formed or left between the door 102 and frame 131. It is clear that when the member 132 is pushed by means of rod 135 the former pushes in turn the piston 115 to release the door.
  • the door 102 comprises an inner lip or ledge 136 in which an aperture 137 is formed for receiving said rod 135.
