An apparatus is provided for securing together two members which are slidable towards and away from each other to provide a respective open and closed (locked) mode, wherein a plurality of devices are adapted to secure the members in a closed mode, and a control unit is adapted to operate the devices. The devices are in the embodiments described spaced longitudinally apart along a vertical edge or stile of a closure member, which may be a patio door, window, or other closure, with the control unit being disposed intermediate the devices and being operatively linked thereto by a connecting device for actuating the devices. The control unit may be driven manually by a control handle, by a solenoid, by an electric or electro-mechanical motor device, or by spring-loaded interlocking devices. The devices cooperate with keeper devices for securing the closure members together in the closed (locked) mode.

A refrigerator including an inner door rotatably coupleable to a cabinet to open and close a storage compartment, the inner door having an opening, an outer door rotatably coupleable to the front of the inner door to open and close the opening of the inner door, a hook locking groove formed on the inner door, a manipulation handle provided to be rotatable with respect to a transverse shaft coupleable to the outer door and including a movable contact part, and a locking member provided to be rotatable with respect to a longitudinal shaft coupled to the outer door, wherein the locking member includes a hook lockable to and unlockable from the hook locking groove, and a passive contact part to selectively contact with the movable contact part.

A storage box includes a door that is coupled to the base. A pivot pin is coupled to the door and is operable between an engaged position, wherein the pivot pin is rotatably engaged with the base, and a disengaged position. The pivot pin is configured to move door-inboard due to contact with the base as the pivot pin moves from the disengaged position to the engaged position.

A locking assembly for a casement window including a frame having an elongated surface, comprising a tie bar guide adapted to be mounted on the window frame surface, the tie bar guide having first and second receiving grooves for slideably receiving segments of a tie bar in a tongue and groove manner, and a tie bar adapted to slide axially in a direction parallel to the window frame surface and having a partially curved profile and a cross-section comprising a flat central portion with a first segment comprising a first tongue and a second segment comprising a second tongue, the first and second segments on opposite sides relative to the central portion. The tie bar is slideably received in the tie bar guide such that the tie bar first tongue is received in the tie bar guide first receiving groove and the tie bar second tongue is received in the tie bar guide second receiving groove, to permit the position of the tie bar to be adjusted with respect to the tie bar guide in the longitudinal direction while preventing movement of the tie bar in a direction perpendicular to the longitudinal direction. One of the tie bar and tie bar guide has an opening in an exterior surface thereof and the other has a projection extending in a direction of the opening, wherein when the tie bar is slideably received within the tie bar guide, the projection and opening act as a detent to maintain the tie bar guide in a desired position.

Enclosure comprises a plurality of bar members translatably attached to an interior surface of the door of the enclosure. Each of the plurality of bar members comprises a projection. A plurality of blocks are disposed on a peripheral edge of the opening of the enclosure's body, such that there is a corresponding block for each projection, and wherein each of the plurality of blocks define a channel for receiving and engaging its corresponding projection. When actuated in a first member, an actuator causes each of the plurality of bar members to translate between a first position and a second position. When the door is in a closed position, translation of the bar members to the first position causes each projection to engage with the channel of its corresponding block to thereby hold the door in the closed position. Translation of the plurality of bar members to the second position causes each projection to be translated out of engagement with its corresponding block such that the door can be opened.

A pet cage door, including a door frame disposed on a cage body, where door frame has multiple insertion buckles protruding toward one side of door frame, the door frame has a door stop capable of rotating relative to door frame to close same, the door stop has a door bolt capable of transversely sliding relative to same, one end of door bolt can be inserted with one of the insertion buckles, the door bolt's other end is connected to a vertical bar capable of transversely moving relative to the door stop along with door bolt, the vertical bar's end portion has a transverse bar that extends toward one side of the transverse bar, the transverse bar's end portion has a turning-back bar that extends toward one side of vertical bar and keeps spaced from transverse bar, and the turning-back bar can be inserted with door frame's other insertion buckle.

Disclosed is a striker for a window or door with a locking system with a striker and locking cam to lock it, which striker is intended to be able to make contact with a contact zone by way of the locking cam. The striker is composed of a foot and a head, whereby the foot in a mounted condition of the striker fits in several different positions between the flanks of the fitting groove, whereby the different positions differ from each other by a rotation of the striker around a geometric axis through a centre point of the foot, and whereby the head possesses at least two different the contact zones the distance of which is different to the geometric axis through the centre point of the foot and/or the thickness is different.

Enclosure comprises a plurality of bar members translatably attached to an interior surface of the door of the enclosure. Each of the plurality of bar members comprises a projection. A plurality of blocks are disposed on a peripheral edge of the opening of the enclosure's body, such that there is a corresponding block for each projection, and wherein each of the plurality of blocks define a channel for receiving and engaging its corresponding projection. When actuated in a first member, an actuator causes each of the plurality of bar members to translate between a first position and a second position. When the door is in a closed position, translation of the bar members to the first position causes each projection to engage with the channel of its corresponding block to thereby hold the door in the closed position. Translation of the plurality of bar members to the second position causes each projection to be translated out of engagement with its corresponding block such that the door can be opened.

The present invention provides a hinge apparatus for attaching a hinged device, such as a lid or door, to a structure to which the hinged device is to be attached. The hinge apparatus operates using hinge pins operable to selectively engage or disengage between the hinged device and the structure. In a closed position all pins can be engaged between the hinged device and the structure to hold the hinged device in the closed position. When desired to move the device to an open position, the hinge apparatus is operated so the pins on the desired hinge side are engaged between the hinged device and the structure while the pins on the opposite side of the hinged device are disengaged between the hinged device and the structure. This allows the hinged device to be rotated about the selected engaged pins, the engaged pins forming the hinge axis.
