A rotary actuator assembly, a household appliance having same and a control method therefor. The rotary actuator assembly comprises an object to be rotated and a rotary actuator configured to match said object. The rotary actuator comprises an output shaft and a driving mechanism for driving the output shaft to rotate. Said object is provided with a shaft hole matching the output shaft. The output shaft and the shaft hole of said object are internally provided with a driving structure and a butt joint structure matching each other in the circumferential direction. A resisting surface and a butt joint surface for pushing said object to move during the rotation of the output shaft are formed between the driving structure and the butt joint structure. A rotation space for manual operation of said object is formed between the driving structure and the butt joint structure.

A door leading edge sensor has: a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and in which a cavity extending in a direction intersecting with the closing direction is formed therein; and a linear pressure sensitive sensor that is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor has an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. A linkage system defines the travel path of the door between closed and opened positions. The linkage system is configured to minimize interference with operator visibility.

A extension mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path including a housing member, an extension member and one or more bushings for positioning the extension member within the housing member. The bushings can provide friction for assisting in hold positions of the extension mechanism. The extension mechanism can be incorporated as part of a biasing strut such as a spring configured strut.

A spacer assembly includes a housing that is configured to couple to a component. The housing includes a central bore. A bumper is coupled to the housing. The bumper includes a bumper support including a shaft that extends within the central bore, and a bumper head coupled to the bumper support.

A door closer (10) includes an exterior housing (11), a spring assembly (12), a ratchet assembly (13), and a clutch assembly (14). The housing has a central tube (17), drive collar (23), a top end cap (52), and a bottom end cap (65). The drive collar includes an indexing pin channel (41) and indexing pin (42) which includes a pawl (45) having a contact surface (47) and a curved bearing surface (48). The spring assembly includes a shaft (73), a spring stop (80), and a helical torsion spring (106) positioned upon the shaft. The ratchet assembly resides within drive collar and includes ratchet wheel (111) having an annular array of ratchet teeth (112) configured to mesh with the pawl of the indexing pin. Each tooth has an undercut contact surface (113) and a curved bearing surface (114). The clutch assembly includes a bottom disc (120) and a top disc (121).

A damper is provided for a fitting for movably supporting a pivoting element or a pull-out element relative to a stationary carrier. The damper includes a damper housing, a fluid chamber arranged in the damper housing, a damping fluid arranged in the fluid chamber, a piston displaceably supported in the fluid chamber, and a sealing element having a first section which bears against or which is configured to bear against an inner wall of the fluid chamber. The sealing element includes a second section, the second section being spaced apart from the inner wall of the fluid chamber and being configured to be moved, preferably pivoted, tilted and/or radially widened, above a predetermined threshold value of a pressure application to the piston, relative to the first section which bears against or which is configured to bear against the inner wall of the fluid chamber.

The present invention provides a hinge and a refrigerator having the same. The hinge comprises a fixing plate, a supporting plate perpendicularly connected with the fixing plate, and a hinge shaft perpendicularly mounted on the supporting plate to cooperate with a shaft sleeve, wherein the outside of the hinge shaft is plastic-encapsulated with a plastic encapsulating case, the plastic encapsulating case is provided with a protrusion protruding horizontally outwards along the extension direction of the supporting plate, and the protrusion is integrally formed with the plastic encapsulating case.

A refrigerator includes a cabinet forming a storage space; a door configured to open and close the cabinet; a hinge configured to connect the door and the cabinet and to support the door to be rotatable; and a damping mechanism providing a damping force to the door while the door rotates in a closing direction after opening the door, in which the damping force of the damping mechanism varies during a door closing process.

Disclosed are integrated sliding glass panel bumper assemblies, frameless sliding glass panel systems that include one or more of the integrated sliding glass panel bumper assemblies, methods for installing the integrated sliding glass panel bumper assemblies, and methods for retrofitting a frameless sliding glass panel system with one or more of the integrated sliding glass panel bumper assemblies.
