Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).

The present invention relates to a refrigerator that allows a user to easily open a door thereof. A refrigerator, according to one embodiment of the present invention, may comprise: a cabinet having a storage compartment; left and right doors for opening and closing the storage compartment from the left and right; a door opening module provided to open the left and right doors; and having a single motor provided to rotate forward and backward; and a control unit for controlling forward and backward driving of the single motor, wherein the door opening module comprises: left and right racks provided to be moved by driving of the single motor so as to respectively open the left and right doors; a power transmission device for selectively transmitting a driving force of the single motor to the left and 4right racks; and a single switch provided to be turned on/off in conjunction with the power transmission device, and wherein the control unit detects a current position of the left and right racks through the switching-on/off of the single switch, and controls the forward and backward driving and stopping of the single motor.

A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

A permanent magnet linear motor. The permanent magnet linear motor including a primary comprising a magnetically permeable core having a first face surface on a first side of the core a plurality of teeth forming a plurality of slots on the first side, and a plurality of multi-phase windings wound to have segments thereof in the slots forming a plurality of magnetic poles at each of the first face surfaces; a permanent magnet pair of opposing polarity configured to produce magnetic flux and cause the primary to exert a force on the secondary when the plurality of multiphase windings are excited by a multiphase source; and a passive ferromagnetic secondary adjacent to but spaced from the first face surface, the passive ferromagnetic secondary being moveable with respect to the primary.

This automatic gate assembly includes at least one first automatic gate and at least one second automatic gate. The or each first automatic gate includes a first frame defining a first passage, at least one first obstacle, chosen from the following obstacles: swing leaf, laterally sliding leaf, pivoting leaf, for selectively closing and opening the first passage, and a first motor assembly for moving the first obstacle. The or each second automatic gate includes a second frame defining a second passage, at least one second obstacle, different to the first obstacle and chosen from the following obstacles: swing leaf, laterally sliding leaf, pivoting leaf, for selectively closing and opening the second passage, and a second motor assembly for moving the second obstacle. The first and second motor assemblies are substantially identical to each other.

A device for coordinated control and operation of double doors having a plate with a rectilinear motion that is associated with links with adjustable lengths that connect the plate to the double doors, with both the first and the second doors opened when one of the doors is opened and sequentially closed when one of the doors is closed.

A vehicle interior component is disclosed. The vehicle interior component may comprise a base providing a compartment, two covers moveable between closed and open positions and a link to couple and decouple movement of the covers. One of the covers may remain open as the other is closed. The link may comprise two arms; one arm may move relative to the other to enable relative movement of the covers. One arm may comprise a depression and the other may comprise a protrusion to engage the depression to couple movement of the arms. The link may comprise a spring to hold the protrusion with the depression to couple movement of the arms; the spring may compress to enable disengagement of the protrusion and depression to enable relative movement of the covers. The component may comprise at least one of a console, a center console, a floor console.

A double-doored lid apparatus includes: a box body; first and second doors; an opening/closing mechanism that opens and closes the first and second doors in conjunction with each other; a locking mechanism that locks the first and second doors in their closed states; an urging member that urges the first and second doors in an opening direction while the doors are locked by the locking mechanism; and a support member that transmits the urging force from the urging member to the first and second doors. The support member includes: a first support portion that supports one end portion of the urging member; and second and third support portions that start to come into contact with the first and second doors, respectively, before the doors reach a predetermined locking position during closing motions thereof, and that support the first and second doors when the doors are locked by the locking mechanism.

A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.

An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.
