Automatic Door Lock Patents (Class 105/395)
  • Patent number: 10169962
    Abstract: The alert system notifies the user, such as a first responder, to a response location at which a responder aid device is located. Such a responder aid device aids the user in responding to an emergency or alarm condition. The alert system communicates with the emergency detection system of a building. The emergency detection system detects emergency conditions, such as fire, carbon monoxide, ammonia levels, and other emergency conditions. The alert system receives the emergency signal from the emergency detection system. The alert system activates at least one beacon or multiple beacons. These beacons show the location of the responder aid device through an alert, such as a visual alert and/or an audible alert. A monitor device alerts the users as to which responder aid devices have been used, applied, or otherwise employed in response to the alarm or emergency conditions.

  • Patent number: 8267016
    Abstract: An open/close control system for an inspection lid adapted not to open while a vehicle travels. An emergency release device is provided behind the inspection lid, where the emergency release device disables power transmission of a driver which opens and closes a side entrance/exit door of a railway vehicle. The emergency release device is installed in a space inside a wall surface inside the vehicle, and the space can be opened and closed by the inspection lid. The open/close control system has a locking device provided in the space inside the wall surface in order to restrict rotation of the inspection lid, and also has an open/close controller which detects traveling of the railway vehicle to actuate the locking device.

  • Patent number: 5413402
    Abstract: A tailgate locking mechanism is provided for locking the tailgate in a closed position against the rear end of the body of a rear loading refuse collection vehicle. The locking mechanism includes at least two fluid operated piston and cylinder locking assemblies, at least one of which is visible to the vehicle operator. Actuation of the piston and cylinder assemblies is sequenced so that the visible piston and cylinder assembly is extended only after the remote, or non-visible piston and cylinder assembly is extended, and is retracted only after the non-visible piston and cylinder assembly is retracted.

  • Patent number: 5092250
    Abstract: An anti-pilferage device is attached to the car body of a railroad flatcar of the type for carrying containers. The device has a mounting plate attached to the car frame at a point adjacent the doors of a container loaded on the car. A barrier is tiltably supported on the mounting plate in a manner which permits free movement if the barrier is bumped during loading of a container. The barrier is movable between a raised, operative position and a lowered, retracted position. A spring biases the barrier to the operative position, wherein it is in the path of a swinging container door to prevent it from being opened. In the retracted position the barrier is below the level of the container floor. A plurality of anti-pilferage devices may be mounted on the car to accommodate containers of various lengths. The barriers are automatically movable between the retracted position and operative position without the need for manual actuation.

  • Patent number: 5025734
    Abstract: An equipment carriage for locomotive air brake valve components including a box-like frame having a rear section separating parallel end sections. The frame is arranged to guidably receive, through an open front section, a group of one or more unitized valve assemblies stacked in vertical, side-by-side relationship, such that an end face adjacent the rear section engages a mating face of a respective header bar that is affixed to the frame at the rear section thereof to provide a pipe bracket to which the locomotive air lines are connected. Such an arrangement, in addition to providing optimum space utilization, permits removal of individual unitized assemblies from the frame without requiring removal of the frame itself or any of the other unitized assemblies, and without disturbing the air line connections.

  • Patent number: 4413568
    Abstract: A method and apparatus for automatically operating a semi-continuous passenger transport system using non-motorized vehicles. Fault conditions corresponding to passengers or articles carried by passengers projecting beyond a surface limiting access to the vehicles in stations are detected. Detection of such fault conditions initiates progressive implementation of fault condition signalling, and slowing and stopping of the tracks which drive the vehicles. These measures are progressively cancelled on clearance of the fault condition.
