A closure for a pressure vessel that includes a neck with a groove defined in the inner diameter, and a door assembly that pivots between opened and closed positions. The door assembly includes a door portion sized to be received in an opening of the neck, a guide plate connected to the door portion and rotatable between locked and unlocked positions, a first lock ring segment positioned radially outwardly of the guide plate and a handle. The guide plate includes a first cam path defined therein that receives a cam member of a first lug assembly that extends inwardly from the first lock ring segment. Rotation of the handle (and guide plate) from the unlocked to the locked position moves the first lock ring segment from a locked to an unlocked position. In the locked position, the first lock ring segment is received in the groove of the neck.

A lock mechanism includes a pedal, a vertical rod, a rod support, a hinge, a hinge support, a hinge lock, and magnets. When the pedal is pushed up the vertical rod, the hinge will lower into a cavity of the hinge lock and the lock mechanism will be in a “locked” mode. To “unlock” the lock mechanism, the user pushes the pedal down the vertical rod, then the hinge will raise out of the cavity of the hinge lock and now the lock mechanism will be in an “unlocked” mode. Then when the user wants to lock the lock mechanism while being inside a bathroom stall, the user will align a door with a wall/stand of the bathroom stall and then push the pedal up so the hinge will lower into the cavity of the hinge lock and the lock mechanism will be in a “locked” mode.

A fenestration system is disclosed. In some examples, the fenestration system includes one or more movable window sashes and a toggle assembly. In some examples, the toggle assembly operates to limit the degree to which the window sashes are opened or otherwise moved relative to one another. In some examples, a window sash may be opened a designated amount before the toggle assembly operates to obstruct it from being further opened.

A refrigerator locking system is used to secure the doors of a refrigerator in closed or open positions. The system includes at least one anchor bar, a locking bracket, a door block and a refrigerator. The refrigerator includes a frame, at least one refrigerator door and a freezer door. The anchor bar is mounted to the frame in between the refrigerator door and the freezer door. The locking bracket is connected adjacent to the frame and is engaged with to the door block to secure the refrigerator door and the freezer door. The door block can be used to press the refrigerator door and the freezer door against the frame, keeping the refrigerator closed. Alternatively, the door block can be positioned in between the frame and both the refrigerator door and the freezer door to keep the refrigerator open.

An emergency entry control system which is particularly adaptable for use with double panic doors typically found in schools, movie theaters, and other public facilities. The system includes a base, connecting bracket, and engagement means designed to be removably secured to the top latching mechanism and/or bottom latching mechanism of a conventional double panic door configuration to prevent double panic doors without a center bar from being opened from the outside. The system is rotated manually to permit the panic doors to operate normally. The system can also be modified with wireless and audio technology to effectuate audible and visual notification and facilitate location and communication during emergency situations like an unauthorized attempt at entry or removal of the system.

A gravity gate latch that is sized and configured to be positioned in the gap between the free end of a gate and a stationary object when the end of the gate is adjacent the stationary object to automatically engage a strike member on the gate. The gate latch has a pair of side plates that are spaced apart to define a space that encloses a lever actuating mechanism and a hook plate. The hook plate has a hook member that engages the strike member of the gate. The lever actuating mechanism has a pair of lever arms, which can be accessed from either side of the gate, that move the hook plate upward to disengage the strike member. A lock receiving member at the bottom of the gate latch receives a padlock to lock the gate latch. The padlock can also be accessed from either side of the gate.

A door security apparatus includes: a base defining a first anchor point and at least one second anchor point; a storage element carried by the base; and a flexible connector carried by the storage element and having a proximal end and a distal end, wherein the proximal end is connected to the first anchor point, the flexible connector being moveable between a first stored position within the storage element, and a second extended position.

A portable securing apparatus which is readily secured to a manway of a vessel having a portal intended to enable entry of service personnel into the vessel is described. The securing apparatus affords an improved grip to assist service personnel to enter the vessel. The securing apparatus is for temporary mounting to the manway. The securing apparatus includes a mounting plate mountable to a flange conventionally provided as part of the manway, and a handle for accommodating manual grasp of the securing apparatus.

A door security device includes a support bar, a first support member, a second support member, and an engagement portion. The first support member is provided on one end of the support bar and is adapted to abut against a surface of an associated door. The second support member is provided at another end of the support bar and is adapted to abut an associated structural surface. The engagement portion is secured to the support bar and is configured to releasably engage a door part of the associated door or an emergency entry device affixed to the associated door. The engagement portion applies a pulling force on the door part in a direction toward the support bar.
