A locking clasp 40 is provided for inserting through an opening 36 in plate 32 in order to prevent the door latch 10 from being opened from the opposite side of the door.

A swing bar door guard includes a door latch having a latch base configured to be connected to a door jamb, a latch bar configured to be connected to the latch base, and first and second bumpers configured to extend through openings in the latch bar. The first and second bumpers each include a jamb bumper portion for contacting the door jamb when in a blocking position and a door bumper portion for contacting the door in the blocking position.

A security latch for a swing bar door guard having a break away rotatable cross-member to further secure the swing bar so as to permit a minimal gap between the door and doorway when the door is opened while the cross-member extends through the swing bar retaining arm passage and is rotated lengthwise across the span to secure the swing bar. The minimal gap inhibits the introduction of a tool into the span along the midsection of the swing bar that could be used to pry the swing bar members apart to release the knob of a swing bar retaining arm.

A hold open rod includes an inner member, an outer member configured to have the inner member slide in and out of the outer member, and a locking mechanism configured to selectively lock the inner member and the outer member with respect to each other. The locking mechanism includes a locking plug configured to move axially along an axis of the inner member and the outer member to a locking position and an unlocking position, a locking dog configured to move radially between a locking position and an unlocking position as a result of a camming action with the locking plug as the locking plug moves axially, and a lock transfer bar operatively connected to the locking plug and configured to move the locking plug to the locking position and the unlocking position when the lock transfer bar is moved.

An assembly according to some embodiments of the disclosure includes an enclosure having a housing and door hingedly attached to the housing and a door stop mechanism which holds the door in an open position. The mechanism includes a link member pivotally connected to the door and to the housing. The link member has an elongated slot which extends along a portion of the link member. The slot has a linear portion and an enlarged opening at an end thereof which is offset from the linear portion. When the door is opened, a fastener, which is either mounted to the housing or to the door, slides along the slot until the fastener is positioned in the enlarged opening to hold the door open.

A door guard assembly is provided comprising: a first part that is attachable to a door; a second part that is attachable to a door frame; an elongate member; a slidable plate that comprises a receiving means; wherein the first part and/or the second part and/or the elongate member further comprise(s) a dampening means; and, wherein the elongate member is attached to the first part or the second part and in use can be engaged with the receiving means of the plate located on the other first or second part respectively when the plate is slid into an operating position such that the receiving means engages the outer surface of the elongate member as the door is opened and the receiving means and elongate member thus limit the opening of the door, and the dampening means absorbs an impact force that may be applied to the door whose opening has been limited in this way.

A door gap lock includes a door leaf part that is configured to be arranged on a door leaf and that has an axially slidably mounted locking bolt, and includes a frame part that is configured to be arranged on a door frame and has a rotatably mounted pivot lever, where the locking bolt can be slid into a guide on the pivot lever and, during a relative movement between the door leaf part and the frame part, the locking bolt is guided in a form-fitting manner in the guide so as to be slidable therein over a defined distance, and where the guide when arranged in the pivot lever has a predetermined breaking point at which the locking bolt breaks through the guide when a defined force is applied to the locking bolt.
