A latching arrangement for a refrigerator door includes a striker unit, a first latch arm and a second latch arm. The striker unit is secured to a cabinet of the refrigerator. The first latch arm is interconnected to the door for pivotal movement about a generally horizontal axis between a latched position and an unlatched position. In the latched position, the first arm releasably engages a first striker portion of the striker unit. The second latch arm is interconnected to the door for pivotal movement about a generally vertical axis between a latched position and an unlatched position. In the latched position, the second latch arm releasably engages a second striker portion of the striker unit.

A door lock mechanism includes a retainer housing mounted to a doorframe and a chain housing mounted to a door plate. The retainer housing includes a retaining slot defined in a lateral side thereof and a lock core mounted therein. A lock piece is pivotally received in the retaining slot and is releasably engaged with the retaining member. A chain is mounted in the chain housing and includes a fixed first end and a second end to which a slide bolt is securely attached. The slide bolt is releasably, slidably received in the retaining slot of the retainer housing. When in a locked position and when a release button is in its first position, the lock piece is stopped by the retaining member and the slide bolt is retained in the retaining slot and thus allows the door to be opened for a small gap. When in a locked position and when the release button is in its second position, the lock piece is disengaged from the lock piece and thus allows removal of the slide bolt from the retaining slot without operation of the lock core.

A tailgate for a utility hauling vehicle is alternatively held in either a closed position or a supported position by a pair of formed rods which are located at the opposite ends of the tailgate. When the rods are in latched positions, they are slightly flexed so as to create a bias which acts between the rods and the tailgate to maintain a rattle-free connection.

An improved deadbolt doorlock bolt assembly has a squeeze-operated "U"-shaped bolt in a channel and may be combined with a receiver assembly. The lock may include an elongated guard with an elongated hook, the guard being hinge mounted on either assembly. When the guard is set, it limits opening of the door to just enough for identification purposes.

A door hold open device for use with fire doors connected to a door closer unit. The hold open device has a latching means that automatically unlatches if the power supply drops below a predetermined threshold or a person attempts to disconnect the power supply. The device includes an electrical actuating means for unlatching the held open door. The actuating means allows a door to be latched open without constant current being supplied to the actuating means, so battery power is possible. The invention may be used with any door closer unit, does not require special wiring, and may include a self-contained power supply and an integral smoke detector.

The present invention is directed to a doorcatch which performs the function of a safety chain for a door and includes a catch part. The catch part is connected to the doorframe and cooperates with a guide on a latch which is connected to the door. Both the catch part and the latch of the present invention are rotatable on horizontal axes. Further, the latch is free for movement up and down and is turnably attached to the door. In addition, the latch includes an axis or spindle arranged at such a level above an axis or spindle of the catch part and is mounted at a right-angled distance between the mounting plate of the catch part such that when the door is closed the parts which cooperate with the guide of the catch part automatically come into a notch. In this manner the catch part cooperates with the guide to automatically force the catch to a locked position when the door is closed either from the inside or from the outside. In another embodiment of the present invention the catch part may be positioned on a door and the latch positioned on a doorframe. This embodiment is utilized in combination with a door which swings inwardly.
