The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.

A hinge device includes a first connection means (3) configured to fixed to a structure or frame and rotatably connected to a second connection means (5) configured to fixed to a door device (1) comprises at least one interconnecting means (7) connected to a sliding means (13) and a friction means (17) with at least one friction sliding block (25) secured to the sliding means (13) and sliding along a respective sliding wall (27) of the first connection means (3) and parallel to a direction of translation of the sliding means (13), wherein at least one arrest means (19) is fixed to or made in the first connection means (3) in proximity to a sliding wall (27) to abut with the sliding means (13) to arrest its stroke towards the closing of the door or of the shutter in correspondence an ajar or breather opening condition (S).

An apparatus and method for moving a window sash relative to a window frame. A window comprises a frame and a sash pivotally connected to the frame. A plurality of members are positioned between the sash and the frame, and the plurality of members are arranged in a series. A plurality of magnet sets comprise at least a first magnet operably connected to one member in the series of members and at least a second magnet operably connected to another member in the series of members. The first magnet is adjacent the second magnet, and at least one of the first or second magnets is an electromagnet. Energizing the electromagnets causes the members in the series of members to move relative to each other and causes the sash to move relative to the frame.

The present invention relates to a door operator system (1) for opening and closing an opening (2), comprising a drive unit (10), a door frame (3) and a door (8), wherein the drive unit (10) is mounted to the door (8) and adapted to move the door (8) between an open (O) and closed position (C), the door frame (3) comprise at least a first frame section (4) adapted to be mounted at a first side (5) of the opening (2), a second frame section (6) adapted to be mounted at a second side (7) of the opening (2), a first track unit (31) moveably connected to the first frame section (4), and a second track unit (32) moveably connected to the second frame section (6), the door (8) is at a first side moveably connected to the first track unit (31) and at a second side moveably connected to the second track unit (32), wherein the door frame (3) is adapted to move the door (8) between the closed position (C) and an intermediate position (I) and to guide the door (8) between the intermediate position (I) and the open position (O).

Provided is an angle-adjustable positioning and self-closing hinge for a highly sealed door, comprising a hinge part, a fixing base, a fixing bar, a threaded sleeve, a threaded ring, a plug, and an adjustment socket; the hinge part is provided with a bushing and a leaf; the fixing base is provided with a bushing; the fixing bar has a screw; a threaded sleeve is fastened inside the bushing, the plug is fastened inside the bushing, and the threaded sleeve and plug are spaced apart; between the threaded sleeve and plug in the two bushings are disposed the fixing bar, the two magnets, two springs, and the adjustment base; the screw of the fixing bar is screwed to the threaded sleeve.

A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.

A hinge apparatus can include a frame component of an aircraft interior component, a door component coupled to an aircraft door assembly, and a linkage assembly operable to rotatably move the door component between an open configuration, a partially open configuration, and a closed configuration. The linkage assembly can include a first hinge body coupled to the door component, a second hinge body coupled to the frame component, a main link pivotably coupled to the first hinge body and having a main link surface, and a first link pivotably coupled to the second hinge body and pivotably coupled to the main link. The first link may have a first link surface that is sized and shaped to mate with the main link surface when the door component is in the partially open configuration, the mating preventing movement of the door component from the partially open configuration to the open configuration or the closed configuration. Related methods are also provided.

An opening and closing body control device for a vehicle includes: a control unit configured to control an opening and closing body drive device driving an opening and closing body of a vehicle to open and close the opening and closing body based on an operation request; and a detection unit configured to detect an obstacle present around the opening and closing body based on a detection result of an obstacle sensor. The control unit sets an operation speed of the opening and closing body to a first speed when the obstacle is not detected during an operation of the opening and closing body, and sets the operation speed to a second speed or less and causes the opening and closing body to stop at a position where the opening and closing body is close to the obstacle, when the obstacle is detected during the operation.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is fixedly provided on the door, a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the guide block; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.
