Definitions
- a removable and replaceable fixture mounting three passenger masks comprises an oxygen supply manifold acting as a strongback upon which is mounted a series of fixed upper mask retaining cradles with lower mask retaining cradles pivotally secured to respective upper cradles.
- the door frame serves to hold all of the lower cradles in mask retaining position, the frame being secured to the housing by a latch which can be tripped by remote control acting through a solenoid end plunger.
- a separate door hinged to the housing opens and closes an opening in the door frame, the separate door having its own releasable catch so that it can be opened for inspection purposes without releasing the masks.
- Another object of the invention is to provide a new and improved compact module for a multiple number of individual breathing masks for an airplane of such design and construction that the module can be effectively and quickly loaded on a bench, then mounted as a unit on the airplane, and then subsequently removed as a unit for reloading on the bench, while in the meantime the module can be promptly replaced by another similar module already tested and found to be in good working order.
- Another object of the invention is to provide a new and improved module for mounting a multiple number of passenger masks which incorporates substantially a minimum of structural parts in that the oxygen supply manifold serving all of the masks acts also as a structural member upon which holding and releasing means are attached.
- Still a further object of the invention is to provide a new and improved modulized passenger mask assembly which when mounted in an overhead housing is confined by a double closure means one of which holds the individual masks in retained position subject to release from a central control and the other of which can be separately opened to permit inspection of the masks and their mounting without it being necessary to release any of the masks.
- Still further among the objects of the invention is to provide a new and improved modulized passenger mask assembly in which a common control for releasing all of the masks simultaneously is positive acting and provided with an overtravel, whereby to insure against any hanging up of the release mechanism.
- Also included among the objects of the invention is to provide a new and improved modulized passenger mask assembly which, although adapted to be bench assembled with auxiliary apparatus, is of such construction that it cannot be mounted in place in operative condition on the airplane without prior removal of auxiliary equipment used in the bench assembly operation.
- the invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter set forth, pointed out in the appended claims and illustrated in the accompanying drawings.
- FIGURE 1 is a fragmentary longitudinal schematic view of the interior of an airplane showing the environment in which the invention is operative.

- FIGURE 3 is a cross-sectional view on the line 33 of FIGURE 2.
- FIGURE 4 is a fragmentary partially sectional view on the line 44 of FIGURE 3.
- FIGURE 5 is a side elevational view of the modulized passenger mask assembly with the housing shown in section.
- FIGURE 6 is a cross-sectional view on the line '66 of FIGURE 3, showing the assembly in released position.
- FIGURE 7 is a longitudinal sectional view on the line 7-7 of FIGURE 6.
- FIGURE 8 is a cross-sectional view similar to FIG- URE 3, showing a door opening for inspection of the release mechanism.
- FIGURE 9 is a bottom view taken on the line 99 of FIGURE 3.
- FIGURE 10 is a fragmentary cross-sectional view showing a means for releasing mounting the mask assembly in the housing.
- a fragment of air frame 10 having a floor 11 on which are rows of seats 12 and 13.
- a ceiling panel 14 has mounted in it over each respective row of seats a modulized passenger mask unit indicated generally by the reference character 15, all of which are supplied from a common oxygen source 16 through an oxygen line 17 in which is a pressure control valve 18.
- the modulized passenger mask unit on the left is shown in released position and that on the right in closed position.
- Each of the modulized passenger mask units 15 is shown as being contained within a housing consisting of side walls 19 and 20, end walls 21 and 22, and an upper wall 23.
- the modulized passenger mask assembly, indicated generally by the reference character 25, is shown mounted in a chamber 26 formed by the walls.
- the passenger mask assembly includes a fixture or manifold 27 which serves simultaneously as a strongbaek as well as to provide a supply of oxygen or breathing gas mixture to individual passenger masks 28, 29, and 30.
- Each mask is provided with a tube 31 for oxygen attached to a connection 32 on the manifold and a lanyard 33 attached to its individual control 34, as shown to good advantage in FIGURES 2 and 3.
- the tubes and lanyards are customarily wound around the body of the mask as shown.
- each of the masks there is provided an upper cradle 35 and a lower cradle 36.
- Each upper cradle 35 is fixed in position by attachment to the manifold 27 by some appropriate means, as for example by welding or brazing.
- the lower cradle 36 in each instance is pivotally attached to an extension 37 of the upper cradle 35 by means of a pivot pin 38.
- an arcuate recess 39 adapted to engage around a mask backup plate 40.
- a similar recess 41 is provided on the lower cradle 36 for the same purpose.
- Spacer bars 42 and 43 extend between the respective upper cradles 35 and serve the double purpose of properly spacing the cradles one from another and also that of retaining the tubes 3-1 and lanyards 33 in their coiled position about the masks.
- a spacer rod 44 serves a similar purpose in spacing the lower cradles 36 one from another as well as retaining the tubes and lanyards.
- a door frame 45 which is substantially U-shaped as readily seen in FIGURE 9.
- the door frame 45 has legs 46 and 47 hinged at respective locations 48 and 49 to the lower edge of the side wall 19 of the housing, and a cross bar 50 connects opposite ends of the legs 46, 47.
- a spring latch 52 pivoted at point 53 upon a lug 54, and spring urged to horizontal position by means of a spring 55.
- An outer end of the catch extends through an opening 56 in the side wall 20 of the housing.
- a longitudinally extending member 57 carried by a mounting 58 on the cross bar 50 is provided with a series of pockets 59 in which rest respective ends of the lower cradle 36.
- a hydraulic ram 60 from which extends a plunger 61, the lower end of which is adapted to be driven against the adjacent end of the spring latch 52 moving against the pressure of spring 55 to tilt the spring latch in a counterclockwise direction as viewed in FIGURES 3, 6, and 8.
- the plunger 61 is provided with a limited amount of overtravel so that following release of the spring latch 52 it will drive against the door frame 45 and cause it to open.
- the hydraulic ram 60 in each instance can be operated by remote control.
- a separate relatively fiat door 65 which fits in and fills a door opening 66 in the door frame 45.
- the door 65 is hinged by means of a hinge 67 to the side wall 19 on the same pivot axis as the locations 48 and 49 at which the door frame 45 is also hinged.
- a releasable catch 68 which is spring urged by a spring 69 in a direction from left to right, as viewed in FIGURES 3 and 8, to a retained position overlying a portion of the mounting 58.
- An access opening 69' adjacent the releasable catch admits a tool such as a screwdriver for releasing the catch and opening the door 4 '65 independently of release of the door frame 45, as shown by the solid lines of FIGURE 8.
- each mask in turn has its tube and lanyard wrapped around it and is placed in its respective compartment portion of the chamber 26 upon one of the upper cradles 35.
- the lower cradle 36 is then lowered in position upon it and a keeper 70 is temporarily applied with one end 71 of the keeper overlying the lower cradle 36 and another end 72 of the keeper overlying the upper cradle 35.
- the keeper applied to retention of one of the masks is left in place while the succeeding two masks are similarly packed.
- the assembly is then placed within the chamber 26 of the housing and the manifold 27 slipped into place over resilient brackets 73, as shown in FIGURE 10, these resilient brackets being anchored to the side wall 20. Once in place, a coupling 74 is applied to interconnect the adjacent end of the manifold 27 to the oxygen line 17.
- the end 71 of the keeper 70 is made extra long so that when the assembly is placed in the chamber 26 of the housing, the keeper will protrude downwardly below the lower ends of the walls of the housing thereby preventing the door frame and door from being closed. This makes certain that the keepers will be removed and the assembly assured of operation before the housing is closed by the closing of the door frame and the door.
- each mask could be individually supplied by its own separate source and actuated by an actuator mechanism comparable to the lanyard and its control.
- the holder for the tank or chlorate candle could be comparable to the resilient bracket 73 described as the means for releasably holding the manifold 27 in position. Inspection in such event could be handled in the same fashion as herein described by opening the door 65. For inspection and repair the entire assembly would be removable in the same fashion as herein described.
- a modulized breathing mask assembly having compartments for mounting a plurality of individual masks in an aircraft interior overhead housing comprising a fixture and releasable attachment means in cooperative engagement with said housing and said fixture, said fixture comprising a relatively stiff structural member extending to positions occupied by all said masks, a plurality of upper cradles set in said fixture adapted to engage upper sides of respective masks, a plurality of lower cradles movably mounted relative to said upper cradles and adapted to engage lower sides of said respective masks, and release means adapted to act between said housing and said respective lower cradles jointly and an actuator for said release means.
- a modulized breathing mask assembly as in claim 2 including mounting said upper cradles on said manifold.
- a modulized breathing mask assembly as in claim 1 including pivotally mounting said lower cradles on said respective upper cradles.
- a modulized breathing mask assembly as in claim 2 including separate hoses and gas control means on said manifold for each mask and common auxiliary retainers extending between said respective upper cradles and between said respective lower cradles for confining said hoses and gas control means at locations adjacent said masks.
