Abstract: A mounting and support bracket which is designed to support and make available to an individual a piece of electronic equipment, such as a small computer and monitor combination. The mounting of the support bracket is to be fixable onto an exterior structure. The mounting and support bracket is to be manually activated to occupy either a fixed position or a movement position. The movement position will permit locating of the computer/monitor in a readily observable position. The fixed position will then fix the bracket in the position that has been established by the movement position.

Abstract: A video monitor is deployed from an aircraft overhead storage compartment via a monitor-drive shaft selectively connected to an electric motor and retracted back into the compartment by a spring connected to the shaft. The monitor has limited rotational movement in both directions relative to the shaft. A bump sensor detects when the monitor has moved from its deployed position relative to the shaft as a result of being struck by a passenger and trips a solenoid. The solenoid, in turn, disengages the monitor-drive shaft from the motor and allows the spring to return the monitor to its stores position.

Abstract: A video monitor deployment/retraction apparatus includes a frame located in an aircraft overhead compartment and a monitor pivotally mounted on the frame for rotation between a stored and a deployed position. A spring biases the monitor to its stored position where is releasably retained by a locking mechanism. A solenoid and actuating arms selectively disable the locking mechanism to allow the monitor to be lowered to its deployed position and enable a latching mechanism when the monitor has reached its deployed position to retain the monitor in that position. The latching means is disabled when the monitor is bumped by a passenger while in the deployed position to allow the spring to return the monitor to the stored position.

Abstract: An avionic tray for supporting an avionic equipment box including a flat bottom section having an opening for communicating with an air plenum chamber and a pair of side rails, of unitary construction with the bottom section, extending upwardly at right angles to and at the lateral edges of the bottom section. A pair of vertically spaced and inwardly projecting back plate support tabs are formed in each side rail, the tabs defining flat surface lying in a plane perpendicular to the bottom section and the side rails. A back plate, having an opening for receiving a connector, is rivited to the support tabs and the bottom section to position the back plate and its associated connector precisely at right angles to the side rails and the bottom section.

Abstract: An avionic tray assembly for supporting electronic instruments on a shelf and controlling the volume of cooling air between the instrument and a plenum chamber is described. The tray bottom includes a pocket formed by a straight side wall extending downwardly at an angle within the range of 30.degree. to 60.degree. and terminating in a rim surrounding the opening to the plenum chamber. A flexible gasket secures an apertured metering plate within the pocket. The gasket includes an upper portion which is arranged to compressed between the bottom of an installed instrument, the sloping wall of the pocket and the upper surface of the metering plate adjacent the periphery thereof to seal the instrument to the plenum chamber so that the apertures in the metering plate control the volume of cooling air flowing between the instrument and the plenum chamber.

Abstract: A wire bundle or cable clamp primarily adapted for use in the aviation industry is disclosed. The clamp includes a flexible strap having a serrated portion and a strap receiving member on which a pawl having a lever portion and a complementary serrated portion is mounted, with the serrated portion being biased against the strap when a first end of the strap is inserted into and through the strap receiving member. The strap includes an enlarged head at the second end and the strap receiving member includes an opening on one side thereof to receive and hold the enlarged head of the strap when it is inserted in a direction perpendicular to a plane formed by the central axis of the strap when the strap extends around a wire bundle or the like so that the enlarged portion of the strap may be looped around the wire bundle and then inserted into the strap receiving member while the other end is secured in the strap receiving member by the pawl.

Abstract: A rack assembly for mounting one or more plug-in type electronic/electrical modules in an aircraft or the like. The assembly provides mechanical isolation to the modules by way of at least two resilient strips positioned on opposite sides of the shelf on which the modules are mounted. The assembly further includes an air plenum disposed adjacent the underside of the shelf for providing cooling air to the modules. The mechanism for providing mechanical isolation performs the additional function of forming part of the plenum. This dual function feature minimizes the amount of space consumed by the disclosed rack assembly.

Abstract: A wire bundle or cable clamp primarily adapted for use in the aviation industry is disclosed. The clamp includes a flexible strap having a serrated portion and a strap receiving member to which the strap is mounted onto the strap receiving member and is biased to engage the serrations of the strap. The strap includes an enlarged head at one end and the strap receiving member includes an opening on one side thereof to receive and hold the enlarged head of the strap when it is inserted in a direction perpendicular to a plane formed by the central axis of the strap when the strap extends around a wire bundle or the like so that the enlarged portion of the strap may be looped around the wire bundle and then inserted into the strap receiving member while the other end is secured in the strap receiving member by the pawl. The free end of the strap extending beyond the pawl may then be grasped and pulled to tighten the strap around the wire bundle.

Abstract: A wire bundle or cable clamp primarily adapted for use in the aviation industry is disclosed. The clamp includes a flexible strap having a serrated portion and a strap receiving member to which the strap is removably mounted. A pawl including a serrated plate is pivotally mounted to the strap receiving member, and is biased to permanently but reversibly engage the serrations of the strap which is looped around an object such as a cable, wire bundle or the like.

Abstract: Accurate alignment of mating electrical connectors on avionic racking equipment is provided by a first circular alignment projection and a second alignment projection toleranced along at least one line for mating with alignment apertures in the electrical connector.

Abstract: An avionic wire clamp assembly having a flexible strap member connected to a housing member is provided. The flexible strap member is adapted to coil about an object such as a wire bundle and to be relatively tightened by the rotation of a fastening member mounted within the housing member. The housing member is mounted within a flexible bracket that has been designed to permit a releasable relative movement with the housing member at a predetermined force to prevent an over tightening of the strap. One of the fastening member and housing member has a locking detent while the other has a complimentary tine for interengagement therewith to provide a lock position to prevent any unintentional release of the strap member.

Abstract: A mounting member for an extractor hold down apparatus permits the extractor to exert both extraction and insertion forces at different angles to, for example, an electronic unit on an avionic rack. The mounting member is provided with a pair of elongated slots that accommodate a cross bar and retaining disks mounted on the power shaft of the extractor. The slots provide an angle range of at least 18.degree. plus or minus 15.degree..
