A device is provided for fastening a first part to a stationary second part, in particular to a part of a vehicle, having a fastening element which can be connected to the first part and has at least one locking element arranged so it cannot be lost, such that it can be brought into a locked position where the first part is joined to the second part and it can also be brought into an unlocked position where the first part is released from the second part, where the fastening element has a top part facing the second part and a bottom part facing the first part, where the top part and the bottom part are designed to pivot about a pivot axis, and the locking element is mounted on the top part.

Device for fixing a first part to a fixed second part

A hinge connection at a breathing gas supply unit between a container lower part (,) and a container door (,), which is fastened, pivotably around an axis, at a rear container edge (,) of the container lower part (,). The connection is provided such that dimensional differences of the container lower part can have only a limited effect on the positioning of the container door in relation to adjacent components of the breathing gas supply unit. The axis of the hinge is designed as projections (,) located at a spaced location from hinge pins (,) of a rail section (,) in the manner of a pin.

A container for an oxygen supply unit is to be improved such that it can be manufactured in one piece and has high mechanical stability at the lowest possible weight. To accomplish this task, the container (1) has reinforcing structures, which extend at least as bead-shaped

Container for an oxygen supply unit for installation in an aircraft

A container door (2) pivotable around a hinge (3) for closing a container for an oxygen supply unit of an airplane is provided with high rigidity to warping at the lowest possible weight. To accomplish this task, the container door (2) is provided with a profile-like reinforcing element (8) extending over at least part of the door edge (7) and with webs (9) connecting the door edges (7), which have fastening structure (11, 12, 13, 15) on the container door (2) and/or the door edge (7).

Container door for an oxygen supply unit

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.

A locking device for a door (3) of a container that is pivotable around a hinge with a first locking part (5) arranged stationary on the container, and a coupling pin (7) connected to the door (3). The coupling pin acts together with the first locking part (5) in an interlocking manner. Such that a simple adjustment of the door (3) is possible, it is provided that the first locking part (5) is attached outside the container on a mounting plane (6) which is integral with the container in the over-lapping area of the door (3), the coupling pin (7) is stroke-changeably mounted in a pin holding device (25), and that the coupling pin (7) has a first adjustment device (27) on its top end pointing to the rocker arm (18), with which, by action of an adjusting tool, which can be inserted into the locking piston (13) from the rocker arm, the depth of engagement of the coupling pin (7) into the first locking part ( 5), which determines the play between the container and the door (3), is changeable.

Locking device for a pivotable door

A testing device (1) with a test button (4) and a rod-shaped plunger (5) for testing a locking device that can be actuated on a door (2) pivotable around a hinge on a container (3) is to be improved in terms of simple design and mounting. To simplify design and mounting, a fastening structure (8, 7) for the movable, rotatable mounting of the testing device (1) is arranged on the door (2). The end (13) of the plunger pointing toward the container (3) is provided with a holding structure (14) which is introduced into a mounting support (16) arranged permanently on the container (3) such that the holding structure (14) is out of engagement with the mounting support (16) in normal operation, and in testing operation. The holding structure engages the mounting support (16) in such a way as to limit the pivoting stroke of the door (2).

Testing device for a pivotable door of an emergency respirator container

A gas-tight packaging arrangement for a device, such as a respirator containing an oxygen releasing chemical. The arrangement includes a safety device for checking the state of the packaging. The safety device acts on an elastic partial area of an evacuated envelope surrounding the device. The envelope may be made of foil or the like. The state of the packaging is indicated through a viewing window provided on a housing surrounding the envelope. A loss of vacuum is indicated by providing a tensioned non-elastic band surrounding at least part of the circumference of the envelope. The non-elastic band includes a visible mark band part which may be viewed through the viewing window. The visible mark band part includes a breaking point, the breakage of the visible mark band part being visible through the viewing window. To tension the non-elastic band, a strain relief element may be provided bridging the visible mark band part such that the belt may be tensioned without breaking the visible mark band part.
