Abstract

This hinge consists of different supports (6) present on the door (3) and hinge pins (8) having first sections (7) which are rotatably mounted in the supports (6), and second sections (10) , which are connected to the container (1), a pivot axis (16) of the hinge being formed by the first sections (7) of the hinge pins (8). The second sections (10) are bent perpendicular to the first sections (7) and are housed in associated sockets (11), present on the container (1), and the lengths of the second sections (10) are calculated so that the container door (3), in the region of the hinge axis (16), can travel relative to the container (1).

Description

i The invention relates to a hinge for a pivoting door, on

  a container of an oxygen supply unit, in an airplane, made up of different supports present on the door and hinge pins having first sections which are rotatably mounted in the supports, and second sections, which are connected to the container, a pivot axis of the hinge being formed by the first sections of the pin

hinge.

  A container, capable of being closed, containing an oxygen supply unit, intended to be installed in an airplane, is known from the document DE 37 19 427 A1. Oxygen supply units of this type are mounted in the ceiling superstructures of the passenger cabin and are used, if necessary, to supply the passengers with oxygen which is essential for breathing. The container, which is closed by a door, contains an oxygen generator and several oxygen masks, the container door, in an emergency situation, can be opened by unlocking an electromagnetic lock and the oxygen masks falling from the container , towards the bottom. In this case, the door should open as widely as possible, so as not to hinder the removal of the oxygen masks. For aesthetic reasons, the container door and the other recessed ceiling elements, which are adjacent to the container, are often provided with convex external contours, which make it difficult to open the container door, since the external contours constitute a stop in the door pivoting stroke. The pivoting stroke of the container door can also be affected by a difference in height between the

  container and adjacent components of the ceiling superstructure.

  The object of the invention is to improve a hinge of the type mentioned so that the pivoting stroke of the container door does not

or only slightly embarrassed.

  This object is achieved thanks to the fact that the second sections are bent perpendicular to the first sections and are housed in associated sockets, present on the container, and in that the lengths of the second sections are calculated so that the container door , in the area of the hinge axis, can perform a stroke relative to the container. The advantage provided by the invention essentially resides in the fact that, thanks to the presence of perpendicularly bent hinge pins which, on the one hand, are mounted to rotate on the door and, on the other hand, are fixed to the container. by being able to carry out a stroke, a parallel movement of the container door, relative to the container, is possible in the hinge area. Thanks to the combination of a rotating movement and an elevating movement, it is possible to cross the edges of the bodies of the adjacent components, which would otherwise constitute a stop for the container door. As edges, mention may be made, for example, of the contours of convex surfaces, which are often used, for

  aesthetic reasons, for elements built into the ceiling.

  Advantageously, torsion springs are mounted, in the region of the first sections of the hinge pins, so as to create a prestress acting on the container door, in the opening direction. It is possible to further improve the opening movement of the container door by having compression springs in the area of the second sections. Depending on the way in which the compression springs are mounted, the upward movement of the second sections inside the sockets present on the container can be promoted or inhibited. When the compression springs are mounted to promote the lifting movement, the container door is certainly quickly opened, but it is possible that it bears only weakly on the adjacent components. Otherwise, the opening speed is certainly reduced, but the compression springs allow the moved door to exert a certain

  prestress with respect to an adjacent bearing surface.

  Alternatively, in the area of the second sections, compression springs are mounted so as to slow down the lifting movement of the

container door.

  Advantageously, the supports which receive the first sections are shaped into U-shaped components, with holes which

receive the first sections.

  By acting on the length of the second sections, it is possible to adjust the maximum pivoting stroke of the container door relative to the container, or relative to the adjacent components. Thanks to a suitable dimensioning of the length of the second sections, it is possible to obtain a pivoting stroke of the door relative to the container

  which can reach up to 180 degrees maximum.

  An exemplary embodiment of the invention is shown in the figures

  and will now be explained in detail.

  Figure 1 is a longitudinal sectional view of a container equipped

a door in the open position.

  Figure 2 is a partial perspective view of a container and the door. Figure 3 is a view similar to that of Figure 2, showing a

variant of a hinge.

  Figure 1 is a partial view of a container 1, having a door 3 fixed on it by means of a hinge 2. The interior space 4 of the container 1 is provided with respiratory protection masks, not shown in Figure 1 , which fall towards the bottom when door 3 opens. On the inner face 5 of the container door 3, there are two U-shaped components 6, in which first sections 7 of two hinge pins 8 are articulated in holes 9. The U-shaped components 6 constitute supports for the first sections 7, on the internal face of the door 3 of the container. Second sections 10 of the hinge pins 8 are bent perpendicular to the first sections 7 and are housed, with the possibility of carrying out a stroke, in two sockets 11 present on the container 1. The second sections 10 are supported, via of compression springs 12, on the sockets 11. On the components 6 are located, in the area of the first sections 7, compression springs 13, by means of which the door 3 is prestressed in the direction of opening. The container 1, as well as the door 3, have contours of convex surfaces 14, 15 which bear against one another in the open state. The length of the second sections 10 is here dimensioned so that the door 3 can pivot at most 180 degrees. This position is shown in Figure 1. The torsion springs 13 promote the opening movement of the container door. The compression springs 12 serve to keep the door 3 under a certain pretension at the surface contour 14 of the container 1 and / or at the level of adjacent components, not shown in FIG. 1. The rotation of the door 3 takes place along a pivot axis 16, which is aligned with the first sections 7 and which is

  moved, during the pivoting movement, parallel to the container 1.

  FIG. 2 represents the constituent elements of the hinge 2 of FIG. 1, seen in perspective, the container I being only partially represented for better visibility. The same components are

  designated by the same references as in Figure 1.

  FIG. 3 represents a variant of attachment of the second sections 10 to the bush 11, according to which the compression springs 12 are placed under the bush 11. The compression spring 12, in this case, is supported by a ring 14, which is integral with the second section 10. This method of attachment promotes the opening movement of the door 3, since the elastic forces of the torsion springs 13 act in the same

  direction than those of compression springs 12.
