Abstract: An improved wheel chock for use with wheeled vehicles, such as aircraft, that is both adjustable in size and that is configured for relatively easy transport, deployment and maneuverability by a single user is disclosed. The wheel chock preferably comprises a lifting end, a rolling end, at least one segment positioned between the lifting end and the rolling end, and a unique and adjustable wheel assembly. The adjustable wheel assembly may be at least partially housed in a pocket formed in the rolling end of the improved wheel chock. The wheel chock may further comprise a tether and an opening for removably attaching said wheel chock to a second wheel chock to prevent unwanted movement of a vehicle wheel in both forward and reverse directions.

Abstract: An inflatable structure that can be easily transported, inflated, assembled, disassembled and stored with minimal if any tools and in a fraction of the time associated with prior art structures. The inflatable structure is comprised of a plurality of interchangeable structural members removably attached to one another, and that afford the user virtually endless design options and superior weatherproofing and insulating qualities. The structural member further comprises a plurality of filaments positioned in an airtight void, wherein said plurality of filaments are in tension when the structural member is inflated.

Abstract: Embodiments of the present invention provide footwear that may be easily adapted for increased traction and/or recreation. Embodiments may include a chamber having a flexible wall, and retractable members coupled to the flexible wall such that when fluid is inserted into the chamber, the retractable members are extended from the bottom of a shoe and when fluid is removed from the chamber the retractable members are retracted into the bottom of a shoe.

Abstract: A push plate assembly sends a signal to a receiver. The push plate includes a housing, a push plate, a signal generator, a biasing member, a first latch element, a second latch element, and a button. The push plate is movably mounted to the housing. The signal generator includes a switch. The switch is in electrical communication with circuitry through which a signal is transmitted. The biasing member is disposed between the push plate and the signal generator. The biasing member biases the push plate away from the signal generator. The first latch element is connected to the push plate. The second latch element is disposed in the housing. The first latch element and the second latch element engage with one another to limit the movement of the push plate away from the signal generator as the biasing member acts on the push plate.

Abstract: A door latch actuator includes a housing, a latch bolt pin actuator, and a spring latch bolt actuator. The housing includes a strike plate defining a latch opening. The latch bolt pin actuator is mounted for movement in the housing between a first extended position and a second retracted position. The spring latch bolt actuator is mounted for movement in the housing between an extended position and a retracted position.

Abstract: An adjustable strike plate assembly includes a door strike housing and an insert plate. The door strike housing includes a strike plate having an opening and walls depending from the strike plate to define a cavity. The insert plate is adapted to mount to at least one of the walls and be received in the cavity to change the effective dimensions of the cavity.

Abstract: An automated assembly for operating a lock in a door includes a housing, a lock conversion assembly, and a powered drive mechanism. The housing includes an opening dimensioned to receive a lock cylinder that has been removed from a lock in a door to which the assembly can mount. The lock conversion assembly extends from the housing and can be received in the opening in the door once occupied by the mortise and/or rim cylinder. The lock conversion assembly operates the door lock. A method for converting a manual cylinder lock to an automated lock is also provided. A deadbolt lock assembly is also disclosed.
