A frame and flexible sheet system for an opening includes a top lineal track body with a top weather-stripping lineal, a bottom lineal track body, and an assembly component with articulating frame segment pair, swinging frame segment, and bottom weather-stripping lineals. The system further comprises an engagement and rolling component for the first top corner of the articulating frame segment pair, an engagement and pivoting component for the second top corner, and a bottom lineal track insert anchoring the bottom corner. The articulating frame segment pair is configured to hang from the top lineal track body. This system provides a versatile and efficient solution for enclosing and securing openings to spaces.

A securable pet door is disclosed. The securable pet door may comprise at least one door, at least one knob, one or more windows, at least one frame, and/or at least one hinge. The knob may comprise a latch for secure closing. When the pet door comprises at least one hinge, the hinge(s) may be inserted into at least one hinge recess so that the door may be securely locked via at least one locking mechanism. The different elements of the securable pet door are configured to be oriented in a predetermined, securable, or customizable manner. The door is configured to open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to the frame(s).

A locking assembly includes a latch configured to move between a locked position and an unlocked position and an adjustment assembly including a first component including an engagement feature and a second component including at least a first cutout defining a first depth and a second cutout defining a second depth shallower than the first depth. The first cutout and the second cutout are configured to receive the engagement feature. The first component is movable relative to the second component between a first position and a second position. In the first position, the engagement feature is engaged with the first cutout such that the latch is laterally spaced from the bath by a first distance. In the second position, the engagement feature is engaged with the second cutout such that the latch is laterally spaced from the bath by a second distance greater than the first distance.

Container closure systems may include various types of latches to secure doors. The latches may present one or more state identifiers, such as open state identifiers and closed state identifiers. Different state identifiers may be presented and scannable based on a state of the door and latch. For example, an open state identifier may be presented and scannable if a door is open and unlocked, and a closed state identifier may be presented and scannable if a door is closed and locked. By scanning and identifying the state identifiers, safe and efficient operations of containers may be facilitated.

A securable pet door is disclosed. The securable pet door may comprise at least one door, at least one knob, one or more windows, at least one frame, and/or at least one hinge. The knob may comprise a latch for secure closing. When the pet door comprises at least one hinge, the hinge(s) may be inserted into at least one hinge recess so that the door may be securely locked via at least one locking mechanism. The different elements of the securable pet door are configured to be oriented in a predetermined, securable, or customizable manner. The door is configured to open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to the frame(s).

In an exemplary embodiment, a locking holder with a mounting element in which the locking holder can be fastened to a door frame in a mounting plane, and with a holding surface which is arranged spaced apart with respect to the mounting plane and can be engaged behind by a door-side locking latch in order to lock the door, the holder includes a holding shoe which can be fastened releasably to a holding element in order to set the distance of the holding surface with respect to the mounting plane.
