A door assembly for a railcar includes a sliding system and a latching system. The sliding system is operable to slide the door to a side of the entrance of the railcar to provide an opening path to an entrance of the railcar. The sliding system comprises one or more rollers used for sliding the door. The latching system is operable to plug the door to the railcar such that the door moves inward toward the railcar, and unplug the door from the railcar such that the door moves outward from the railcar. The latching system comprises a lever operably coupled with two or more gears. The lever turns a particular number of rotations in a first direction to plug the door to the railcar. The lever turns the particular number of rotations in a second direction to unplug the door from the railcar.

A door stopping mechanism for a sliding glazing patio door or like, independent in construction from the sliding glazing for which it is stopping, includes a vertical and horizontal component. The horizontal component is within the track of the door, while the vertical component is selectively attached to the sliding member. The mechanism is changeable from a locked to unlocked position by manipulation by a user at mid-height of the door, and at least one of the locked or unlocked positions is maintained by gravity.

A window security device has a support rod capable of securely contacting an upper window frame and a lower window frame. The device has two horizontal arms extending from away from the support rod terminating in thin blades capable of sliding between a first stationary window and a second sliding window sash. The device prevents unwanted tampering with the device by children located on the inside of the window as well as burglars located on the exterior of the window and to be easily removed in the event of a fire. The length of the device's blade can be adjusted allow a window to safely remain open a specified distance, and the device's arms can be adjusted to fit many different widths of windows. When the blades are disposed between the windows, the window is slid open and contacts the window stop, located at the end of the horizontal arms.

A window locking apparatus includes a proximal cross brace, a distal cross brace, a first track brace, and a second track brace. The first track brace is positioned parallel to the second track brace. The proximal cross brace is perpendicularly positioned in between the first track brace and the second track brace. The distal cross brace is perpendicularly positioned in between the first track brace and the second track brace, wherein the proximal cross brace and the distal cross brace are positioned offset of each other. The proximal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The distal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The removable connections of the second track brace allows the window locking apparatus to be installed or removed from a window.

A sliding door brace apparatus for creating a strong seal on a sliding glass door includes a fixed clamp having a receiving channel to receive an outer frame of a sliding door and a set screw extending into the receiving channel. An extension arm is coupled to the fixed clamp. A rail has a proximal end coupled to the extension arm and a distal end. A slider is coupled to the rail and a trigger is coupled to the slider to ratchet the slider towards the distal end of the rail. A release button is coupled to the slider to allow the slider to move towards the proximal end of the rail. A door wedge is coupled to the slider to engage a panel frame of the sliding door.

A device for placing in a sliding door or sliding window frame that adds additional security to prevent a sliding door or sliding window from being opened. The device is a secure locking device which comprises of a main bar and a lever bar that are connected to each other such that lever bar may pivot where it is connected to the main bar. The main bar is adjustable such that a length may be adjusted to allow the secure locking device to fit within varied sizes of sliding door/window frames. The secure locking device is also comprised of a locking mechanism that is controlled by a lever actuator and a lock button which are configured onto the main bar. The secure locking device is easily accessible by a user to lock and unlock in order to secure and unsecure the sliding door. The secure locking device is easy to position in a track of the sliding panel and does not require any need to secure into place.

In a high-security sliding-door apparatus for closing and opening a corridor, the door having (a) a door frame having a track and a bi-directional effector, (b) a carriage having track-engaging rollers, (c) a slide plate slidably secured to the carriage and driven by the effector, and (d) a controller controlling slide-plate movement and enabling the door to be continuously closed but not locked, the improvement comprising centering apparatus for relative positioning of the slide plate and carriage, the centering apparatus including (1) a yoke attached to the slide plate at a yoke pivot and having a yoke cam surface thereabove, (2) a carriage-attached yoke-cam follower, and (3) springs having proximal ends attached to the yoke spaced above the yoke pivot and distal ends each attached to the carriage at points offset from the yoke pivot in opposite lateral directions, centering the door with the slide plate when unlocked.

A device for securing sliding windows and doors includes a telescoping bar and a plate. An end of the bar and the plate together form a connector pair that couples the bar end to the plate in one of a separable orientation and an inseparable orientation according to a relative angle between the bar end and the plate. The connector pair allows the bar to be separated from the plate in the separable orientation when the relative angle is a first angle, and the connector pair prevents the bar end being separated from the plate in the inseparable orientation when the relative angle is a second angle. A lock in the locked position physically prevents the relative angle between the bar end and the plate being changed from the second angle to the first angle. A T-bar or side-wing may prevent unlocking when the window or door is open.

A smart window/door opening-closing device that can easily be installed for use with an existing door or window or can be built-in by the door or window manufacturer, can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet and/or (c) automatically by a voice command, is easily disengaged when use is not desired, provides safety and security to prevent unwanted opening or closing of the door or window, and is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.
