Abstract
Abstract A hinge for a foldable rail section for mounting a container of an oxygen supply unit in an aircraft, with a first hinge part on the rail section and a second hinge part on the edge of the container, and with a container door, which extends in parallel to the longitudinal side of the rail section and is pivotable around a joint on the rear edge of the container. The connection of the hinge to the container is simplified, and a stop is provided for the container door. The first hinge part is formed as of a bead (11), which is made in one piece with sections of the longitudinal side of the rail section (9), wherein slots (12) are present in the sections of the bead (11) not made in one piece with the rail section, and the second hinge part is formed as tongues (13) made in one piece with the rear container edge (4) corresponding to the outer shape of the bead (11), and the said tongues extend into the slots (12), and the tongues (13) are raised at the tongue end (15) such that the tongue ends (15) form a stop limiting the pivoting stroke of the container door.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
204 words
A container and hinge, comprising: a container of an oxygen supply unit for an aircraft; a foldable rail section for mounting the container; a container door connected at an edge of the container, said container door extending in parallel to a longitudinal side of said rail section and being pivotable around a pivot axis on a rear part of said edge of said container; a first hinge part on the rail section, said first hinge part including a bead integrally formed with a sequence of sections of a longitudinal side of the rail section, slots being provided between said bead and said longitudinal side of the rail section, said slots being provided adjacent sections of said bead which are not integrally formed with the sections of the longitudinal side of the rail section; and a second hinge part including tongues formed integrally in one piece with a rear container edge and a front container edge, an outer surface of said tongues being adapted to a circumferential shape of said bead, said tongues extending into said slots, said tongues of said rear container edge being raised at a tongue end, whereby said tongue end defines a stop limiting a pivoting stroke of said container door.
Claim 2
Dependent Claim
204 words
A container and hinge, comprising: a container of an oxygen supply unit for an aircraft; a foldable rail section for mounting the container; a container door connected at an edge of the container, said container door extending in parallel to a longitudinal side of said rail section and being pivotable around a pivot axis on a rear part of said edge of said container; a first hinge part on the rail section, said first hinge part including a bead integrally formed with a sequence of sections of a longitudinal side of the rail section, slots being provided between said bead and said longitudinal side of the rail section, said slots being provided adjacent sections of said bead which are not integrally formed with the sections of the longitudinal side of the rail section; and a second hinge part including tongues formed integrally in one piece with a rear container edge and a front container edge, an outer surface of said tongues being adapted to a circumferential shape of said bead, said tongues extending into said slots, said tongues of said rear container edge being raised at a tongue end, whereby said tongue end defines a stop limiting a pivoting stroke of said container door.
Claim 3
Dependent Claim
53 words
A container and hinge according to claim 1, wherein: between two adjacent tongues, said second hinge part is provided with elastic projections formed in one piece with one of said front and rear container edge, said elastic projections surrounding said bead, at least partially, on one of said front and rear container edge.
Claim 4
Dependent Claim
42 words
A container and hinge according to claim 1, wherein: said rear container edge is bent such that a break formed between said tongue and said tongue end on said rear container edge is located under said pivot axis of said container door.
Claim 5
Dependent Claim
29 words
A container and hinge according to claim 1, wherein: said bead has a cross sectional area reduced by a thickness of said tongues in an area of said slots.
Claim 6
Dependent Claim
40 words
A container and hinge according to claim 1, wherein: said raised tongue end has a length dimensioned such that said raised tongue end is in contact with an inner side of said container door when said container door is closed.
Claim 7
Dependent Claim
26 words
A container and hinge according to claim 1, wherein: said second hinge part on said container edge has bead-shaped depressions in an area of said tongues.
Claim 8
Dependent Claim
225 words
A container and hinge assembly, comprising: a container of an oxygen supply unit for an aircraft, the container having an edge; a foldable rail section for mounting said container, said rail section including a plurality of spaced apart rail section parts on a longitudinal side of said rail section; a container door extending in parallel to a longitudinal side of said rail section, said container door being connected to said container pivotable around a pivot axis on a rear container edge; a first hinge part provided on said rail section, said first hinge part including a bead with a bead part formed integrally on each spaced apart rail section of said longitudinal side of said rail section, and a bead part not formed integrally with said rail section, and slots formed in said rail section, each slot being adjacent to a said bead part not made in one piece with said rail section; and a second hinge part including tongues formed in one piece with said rear container edge, said tongues having a shape corresponding to a circumferential shape of said bead, said tongues extending into said slots, said tongues of said rear container edge being raised at a tongue end with said pivot axis positioned above said tongues, whereby each said tongue end defines a stop limiting a pivoting stroke of said container door.
Claim 9
Dependent Claim
225 words
A container and hinge assembly, comprising: a container of an oxygen supply unit for an aircraft, the container having an edge; a foldable rail section for mounting said container, said rail section including a plurality of spaced apart rail section parts on a longitudinal side of said rail section; a container door extending in parallel to a longitudinal side of said rail section, said container door being connected to said container pivotable around a pivot axis on a rear container edge; a first hinge part provided on said rail section, said first hinge part including a bead with a bead part formed integrally on each spaced apart rail section of said longitudinal side of said rail section, and a bead part not formed integrally with said rail section, and slots formed in said rail section, each slot being adjacent to a said bead part not made in one piece with said rail section; and a second hinge part including tongues formed in one piece with said rear container edge, said tongues having a shape corresponding to a circumferential shape of said bead, said tongues extending into said slots, said tongues of said rear container edge being raised at a tongue end with said pivot axis positioned above said tongues, whereby each said tongue end defines a stop limiting a pivoting stroke of said container door.
