Abstract:
An inflatable evacuation slide system includes an inflatable evacuation slide stored in a packboard compartment the cover panel of which is retained by a plurality of frangible pneumatic latches. The frangible pneumatic latches each comprise a tension member one end of which is attached to the packboard housing and the other end of which is releasably attached to the cover panel. In normal operation, a pneumatic signal operating on an actuator piston withdraws the piston to allow the latch mechanism to release the cover panel. In the event of a failure of the release mechanism, since the releasable latch secures the cover panel to the frangible tension member rather than to the packboard directly, the force of the inflating evacuation slide breaks the frangible member allowing the cover panel to drop away with only a brief delay in slide deployment.
Abstract:
A door catch includes a back plate having two laterally symmetric sleeves formed on a front face thereof. A slot is provided on the back plate behind each of the sleeves at a predetermined position to communicate with an inner space of the sleeve, and an insert plate is inserted from a back face of the back plate into the sleeve via the slot to confine a steel ball and a spring in the sleeve, such that the springs not only normally push the steel balls forward to partially project from front open ends of the sleeves for tightly clamping a corresponding stop post between the balls, but also tightly push against the insert plates to hold the latter in place. The insert plates are held down in place in the sleeves by a wall when the back plate is mounted on the wall with fastening elements.
Abstract:
A booster actuator 10 may be positioned between the solenoid 12 and a valve 14, and increases the energy output from the solenoid to activate the valve. The booster actuator 10 may include a force input member 28 and a force output member 30 each linearly movable with respect to a body 20 from an initial position to an activated position. A coil spring 46 biases the input member to the initial input position, while a plurality of disk springs 48 bias the output member 30 to the activated output position. A plurality of linking members 32 each pivotable with respect to the body normally retain the force output member in the initial position, but upon movement of the input member to the activated position release the force output member in response to the disk springs.
Abstract:
A push button lock. The push button lock has a main housing with an aperture formed therethrough, a plunger which is axially moveable in the aperture of the main housing, and a ball retainer positioned in the aperture of the main housing. The ball retainer has a central aperture formed therein through which the plunger extends and a protrusion. Balls are placed on the ball retainer. An actuator is located in the main housing aperture above the ball retainer and is rotatable to an open position, wherein the actuator is in position to be pushed down to prevent the balls from moving away from the plunger shaft and thereby prevent the plunger shaft from moving relative to the ball retainer, and a locked position, wherein the balls are not retained against the plunger shaft and the plunger shaft can move relative to the balls retainer. A lock button having a lock housing and a lock cylinder is provided, with the lock cylinder being adapted to turn the actuator from the opened position to the locked position.
Abstract:
A multifunction door knob assembly for allowing for a door to be opened easily without being forced to turn a door knob. The inventive device includes an engagement mechanism is disposed within the side opening of the door. The engagement mechanism includes a cylindrical casing having open opposed ends. One of the opposed ends has a ball bearing slidably disposed therein. The ball bearing engages a door casing in a closed orientation. Opposed from the ball bearing in the opposed open end of the casing is a pressure block. The pressure block is slidably disposed within the casing. The pressure block has a pair of tabs disposed thereon to preclude disengagement from the casing. A spring is disposed between interior ends of the ball bearing and the pressure block. A swing arm is disposed within the side opening of the door inwardly of the engagement mechanism. The swing arm has an outer portion and an inner portion. An inner end of the inner portion is pivotally coupled within the side opening of the door. An outer end of the outer portion has a roller ball disposed therein within a U-shaped housing. The roller ball selectively engages an inner end of the pressure block. The inner portion is freely rotatable with respect to the outer portion. The inner portion has a coil spring coupled thereto to facilitate retractable rotation of the inner portion. The inner portion has a cord wrappedly coupled thereto.
Abstract:
A quick connect/disconnect device and method for manually demountably attaching carrier bars to an endless train comprising a conveyor adapted for conveying pellet-like items in a pellet marking machine is disclosed. The device comprises an elongated shank with an enlarged head and a central bore coaxial therethrough. Radially oriented passages disposed adjacent to the end of the shank opposite the head house balls which extend outwardly beyond the outer surface of the shank when a plunger within the central bore is biased to its normal position. Moving the plunger against its biasing spring allows the balls to retract partially within the central bore, allowing the shank to be inserted into mounting holes in the carrier bar and receiving holes in the endless train. When mounted on the train the carrier bar and endless train are sandwiched between the enlarged head and the extended balls, the carrier bar being retained to the endless train thereby.
Abstract:
A mobile support unit such as an IV stand or the like coupled to a mobile hospital bed, gurney or wheelchair by a latch mechanism which provides hands free operation thereby avoiding the need for a nurse or care provider to manually manipulate the latch to secure the units together for tandem transport. Further, the latch mechanism according to this invention includes a clutch which prevents relative movement of the IV stand or support unit with respect to the hospital bed during transport up to a specific adjustable torque level thereby avoiding the problem of the IV stand or support unit swinging freely relative to the bed during movement. Further, the clutch permits movement of the IV stand or support unit through an arc relative to the bed when a specified force is applied as required by the nurse or care provider to reposition the IV stand or support unit relative to the bed and provide increased access to the patient or the like. The IV stand includes a relatively heavy base which provides a low center of gravity for the unit and offers a very stabile mobile IV stand which resists tilting or tipping during transport.
Abstract:
A control panel door that is pivotally connected to the beznet of a television receiver. The beznet has a pair of radial protrusions which cooperate with a single radial protrusion of the door to secure the control panel door in a closed position. The door is provided with enough lateral movement to allow the single door protrusion to slide past the beznet protrusions when the door is rotated to an open position. The door protrusion and the beznet protrusions also align the control panel door with the beznet when the door is rotated into the closed position.
Abstract:
A resealable fastening device which is suitable for use in gripping and holding a stud. The device comprises an integrally cooperating collar with an elongated tubular housing which forces movable balls under the influence of a compression spring against a tapered surface to grip a stud. A camming device is required to install and disengage the resealable fastener.
Abstract:
A remotely controlled door lock for a dog cage is provided. The door lock includes a pair of solenoids connected to a latch bolt, and a main controller which receives a radio frequency control signal from a remote radio transmitter. The main controller decodes the signal and sends it to one of the solenoids to retract the latch bolt from engagement with the cage door, or extend it into engagement therewith.
