Abstract:
A method for operating a building closure having the shape of an overhead sectional door or of a garage door including at least one spring-loaded counterweight device and an electrical drive device is disclosed. A control unit simultaneously monitors the position of the building closure and a motor current for the drive device. When the building closure is in an open or a closed position, the motor current is reduced and maintained at a level to residually energize the drive device to reliably maintain the building closure in a desired position.
Abstract:
A spring assembly is provided for an upward acting door that travels on a travel path while opening. The assembly includes a shaft, a torsion spring and a second spring. The torsion spring is connected to the shaft and provides a lifting force for the door throughout the travel path. The second spring is connected to the shaft and provides a lifting force for the door during only a portion of the travel path. In another aspect, a spring assembly is provided for an upward acting door that travels on a travel path while closing. The torsion spring is connected to the shaft and provides a weight supporting force for the door throughout the travel path. The second spring is connected to the shaft and provides a weight supporting force for the door during only a portion of the travel path.
Abstract:
In this dishwasher 1, a spring 33 utilized for moving a door 7 up and down is accommodated within a column 6 of a washer body 2, so as to be confined within the column 6, whereby the appearance becomes better while the spring 33 is protected against water. Also, the space between left and right columns 6, 6 can be utilized as a washing chamber 3, thus making it possible to expand the washing chamber 3, whereby the dishwasher can be made smaller while keeping the capacity of the washing chamber 3.
Abstract:
An appliance includes a chassis defining a cavity and having an opening for accessing the cavity and a door assembly joined to the chassis. The door assembly includes a door for closing access to the opening, and the door assembly further includes a door lift sub-assembly having a horizontal slide and a vertical slide. The door is coupled to one of the horizontal slide and the vertical slide. The horizontal slide is moveable between a recessed position and an extended position and is configured to move the door in a substantially horizontal direction. The vertical slide is moveable between a closed position and an open position and is configured to move the door in a substantially vertical direction.
Abstract:
An appliance including a chassis having a top, a bottom, a left and right side opposite one another other and connecting the top and the bottom, and a back opposite an opening. The chassis defines a cavity with an opening for accessing the cavity. A door assembly joined to the chassis includes a door for closing access to the opening and a first and second door lift sub-assemblies. The door lift sub-assemblies are configured to move with the door in a first direction and a second direction different than the first direction. At least one stabilizing device operatively connects the first and second door lift sub-assemblies to synchronize movement of the first and second door lift sub-assemblies in the first direction.
Abstract:
A power closing assembly operates a closure panel hingedly secured to a motor vehicle. The power closing assembly includes an actuator mounted to the motor vehicle, a movable striker also mounted to the motor vehicle to receive the closure panel's latch, and a rotary power cable connecting therebetween. The actuator has a closure cable on a spooling drum extending to the closure panel for closing from an open position when the actuator operates. The movable striker moves between a nominal inboard position and an outboard position. A rotary power cable connects between a provided output on the actuator and an input on the striker so that the striker's movement is powered and synchronized by the actuator. With the closure panel open, the actuator begins a closing cycle by driving in a direction to spool in the closure cable extending to the closure panel. The actuator's direction, using the rotary power cable, simultaneously causes the striker to move outboard. When the closure panel is pulled completely closed, the striker has also moved to its outboard position whereupon the closure panel's latch readily receives and engages the striker. Upon engagement, the actuator reverses its drive direction. This reverse direction causes both the actuator to reset with respect to its closure cable spooling drum and the rotary power cable to turn in the other direction causing the striker to return to its inboard position and fully close the closure panel against its seal load.
Abstract:
A parallelogram hinge for vertical-movement doors comprises a first plate designed to be fastened to the furniture flank, a second plate designed to be fastened to the door and two superposed arms pivotally mounted to the plates to form an articulated parallelogram. A spring for movement balancing is connected to the upper arm at an intermediate position between the arm extremities hinged to the plates and is connected to the first plate at a point below the pivot point of the lower arm on the first plate. This enables very reduced bulkiness in the direction of the furniture depth, achievement of a great opening angle and better operation of the spring embodied by a gas piston.
Abstract:
A hydraulic hinge for the lid of a food serving vessel in a buffet restaurant includes a hinge block, a shaft pivotally mounted to the hinge block, an annular hydraulic chamber within the hinge block and at least partially surrounding the shaft, and a one-way valve having an inlet port and an outlet port each communicating with the hydraulic chamber and allowing hydraulic fluid to flow from the inlet port to the outlet port but not vice versa. The hinge further includes a rotary piston extending from the shaft across the annular hydraulic chamber and adapted to pivot with the shaft between the inlet and outlet ports and comprising a flow restrictor allowing hydraulic fluid to flow relatively slowly therethrough. This prevents the lid from dropping after patrons release the lid.
Abstract:
An apparatus includes a door, in particular, a cooking appliance door, through which a useful space can be closed, and having a stowage space, into which the door can be lowered at least partly, guided by a guide system that has a pivot axis and at least one guide element guided in a guide track, through which the door is guided in its movement along the guide track during a pivoting movement. The position of the pivot axis is fixed in the housing.
