The present invention provides a locking device based on a rack and pinion mechanism for securing a double door system, for example cabinets with double door. The locking system comprises a pair of jaws extending from a central housing and adapted to mount over the two handles of double door and the jaws are operably coupled to a gear assembly enclosed in the central housing. The gear assembly could be cranked to move the jaws laterally in extended and retracted position for tightening and loosening the locking device over the handles.

An imaging device with a two door interlock system for detecting a positional state of orthogonally mounted first and second access doors of the imaging device. The two door interlock system includes a mounting assembly rotatably mounted to a frame of the imaging device and movable by the first access door between a first position and a second position, and an actuator projecting from an inner surface of the second access door, and a sensor positioned on the mounting assembly and providing an output signal that changes between a first state and a second state. The output signal being in the first state when both of the first and second access doors are in their respective closed positions and in the second state when at least one of the first and second access doors are in their respective open positions.

A security gate including an outer gate and an inner gate for selective passage of people and/or pets therethrough. In one example, the security gate includes: an outer frame; an outer gate at least partially disposed within the outer frame; an inner gate disposed within the outer gate, the inner gate comprising an inner frame having at least one recess; a door at least partially disposed within the inner frame; and at least one projection extending from the outer gate and engaging the at least one recess for supporting the inner gate within the outer gate.

This invention relates to a locking arrangement 10 which includes a body 12 and a locking member 14 which is displaceable relative to the body 12. The locking member 14 defines at least one striker element engagement formation 18.1, 18.2 which is configured to engage a striker element 100 for part of its displacement relative to the locking arrangement 10 along a predetermined displacement path. The locking member 14 is displaceable between first and second spaced apart positions in each of which the engagement formation 18.1, 18.2 is positioned such that a said striker element 100 is releasably engageable therewith and between which a said striker element 100 is in engagement with the engagement formation 18.1, 18.2. The locking arrangement 10 further includes a securing mechanism 16 which is configured to secure the locking member 14 releasably in at least one of the first and second spaced apart positions.

A door mullion receptacle box assembly includes a toe plate, a channel box and block components. When a mullion is removed from a building/room opening, the toe plate may be fixed in the mullion receptacle box thus creating a uniform threshold across the width of the door openings. Using the assembly described herein, however, there are no large diameter holes in the top of the toe plate and no projections into the opening that could be a trip hazard. The present assembly replaces traditional fixed sill blocks mounted to the floor, or to the top of a threshold to anchor the bottom of conventional mullions. A typical mullion is locked in place with a lock at the top of the mullion. When installed, this mullion is placed over the sill block at the sill and tilted into place and locked into a header block at the top of the mullion. However because the components of the conventional sill blocks project up into the mullion from the thresholds, they become a trip hazard and a liability when the mullion is temporarily removed.

A latching mechanism is described comprising: a latching component and a retaining component; wherein the latching component comprises means for receiving a hook in use, and a pivoting feature which is configured to allow said latching component to pivot relative to said retaining component.
