A door opening/closing device including a door, a locking hook mounted on an inner surface of the door, a solenoid mounted in a device housing, a locking lever connected swingably to a movable iron core of the solenoid and having a free end on an opposite side of a connection portion, and a controller for controlling the solenoid, in which the controller executes control so as to, if the door is closed and locked, separate the locking lever from the locking hook to release locking in conjunction with the movable iron core retreated by an electromagnetic attracting force by executing conduction control of the solenoid, and maintain an unlocked state while the door is closed by executing non-conduction control of the solenoid after unlocking and bringing the free end of the locking lever into contact with the locking hook by a return spring force.

A hook of a lock structure is rotatably supported by a knob. Therefore, a biasing force of a hook biasing spring can be regulated independently from a knob biasing spring. Accordingly, the biasing force of the hook biasing spring can be regulated smaller than a biasing force of the knob biasing spring. As a result, sounds generated when locking the lock structure can be decreased.

A handle mechanism is to be mounted on a slidable plate and to slide the slidable plate relative to a chassis. The handle mechanism includes a handle and an engagement component. The handle is adapted to be pivotably disposed on the slidable plate so as to have an engaged position and a disengaged position. The engagement component is slidably disposed on the handle and adapted to contact the chassis to slide the slidable plate into the chassis. The engagement component has a contact surface, and the contact surface has an edge located away from an axis of the handle. A distance between the edge of the contact surface of the engagement component and the axis of the handle in the engaged position is smaller than a distance between the edge of the contact surface of the engagement component and the axis of the handle in the disengaged position.

A latch mechanism for securing together first and second parts of an assembly includes a first latching component comprising a retainer having an engagement surface; a resilient connector connecting the first latching component to the first part and applying a resilient action on the first latching component resisting displacement of the first latching component in a latching direction; and a second latching component comprising a projection having a latching surface and attached to the second part with the projection projecting outwardly from the second part to a free end of the projection. The engagement surface is engageable with the latching surface to prevent displacement of the first latching component relative to the second latching component in a direction opposite to a latching direction. The latch mechanism further comprises a guide surface on the second latching component and a limb provided on the first latching component.

An appliance door latch system is provided that automatically aligns latching components each time an appliance door is closed with a pre-latching catch alignment system. The pre-latching catch alignment system may include a floating catch carrier that is deflected by a door-mounted latch feature to passively reposition a catch to properly align with the striker assembly.

A hook of a lock structure is rotatably supported by a knob. Therefore, a biasing force of a hook biasing spring can be regulated independently from a knob biasing spring. Accordingly, the biasing force of the hook biasing spring can be regulated smaller than a biasing force of the knob biasing spring. As a result, sounds generated when locking the lock structure can be decreased.

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.

In order to lock the door proceeding from the open position, a locking bar is brought into the locked position under tension of a spring element, in which locked position a closing force acting on the locking bar is determined by the spring element, and, in order to unlock the door, the locking bar is brought out of the locked position into an unlocked position with the aid of an actuating force that is not applied by the spring element, and, after the striker has moved out of the locked position, the locking bar moves into the open position by means of the force of the spring element.

A door-lock device having a casing, a slider, arranged within said casing, a locking hook with a body and a locking portion, said body having a cam shape which abuts said slider, said locking hook capable to assume a rest position, in which said locking portion is disengaged from said recess, and an operative position, in which said locking portion is inserted, and engaged with, said recess, and pushing capabilities, for keeping said slider in contact with said cam surface, so when said door is closed, said locking hook passes from said rest position to said operative position, said cam shape compressing said pushing capabilities, so that said pushing capabilities accumulate energy and said slider exerts a resistance to the closing of said door, and, then, allowing said pushing capabilities to release said energy, so that said slider exerts a return action on said locking hook and on said door.

Disclosed is a refrigerator including a cabinet having a storage compartment, an inner case defining an external appearance of the storage compartment, a first door rotatably installed to the cabinet for opening or closing one side of the storage compartment, a second door rotatably installed to the cabinet for opening or closing a remaining side of the storage compartment, a pillar provided on the first door, the pillar being rotated so as to come into contact with the second door and having a pillar protrusion protruding from an upper side thereof, and a pillar rotation unit provided on a ceiling of the inner case for rotating the pillar.
