The system includes a rod extending between a first end portion and a second end portion and a restraint receiving the second portion of the rod therein with the first end portion of the rod extending through an end cap on the restraint. A biasing member is disposed within the restraint between the end cap and the second end portion of the rod, wherein the biasing member is in a compressed configuration within the restraint, and wherein the first end portion of the rod is operatively engaged with a door pivotably secured to the cooking appliance, and the restraint is pivotably connected to the cooking appliance.
Abstract:
A door hinge for a household appliance, the household appliance including a body and a door, the door being movable about a horizontal axis between a substantially vertical closed position and a substantially horizontal opened position. The door hinge includes a housing couplable to the body, a door lever pivotably mountable on the door for movement about a main shaft, a weight compensating spring and a closing spring. The weight compensating spring holds the door substantially in a position of equilibrium when the door is opened and the closing spring applies a self-closing force shortly before the door reaches the closed position and applies a closure maintaining force when the door reaches the closed position. Further included is a dampening device that counteracts one or both of a closing force and an opening force.
Abstract:
A refrigerator equipped with a door opening device opening doors by driving a motor and a method of controlling the same. In the method of controlling the refrigerator includes a door opening device including a plurality of sliding bars selectively opening first and second doors, a motor opening the first door or the second door by moving back and forth the sliding bars in directions opposite to each other, a plurality of position detectors detecting at least one protrusion provided at one side of the sliding bar, a switch unit inputting door opening signals, and a controller controlling operation of the first door and the second door according to the door opening signals. If door opening signals used to open the first and second doors, the door opening device is controlled so that the first and second doors are easily open/closed.
Abstract:
A mechanism for installing a door or other similar closure device with rotary and translational motion, of the type comprising the following elements to be associated with a leaf first pivoting means, which form a first vertical axis (11) for the pivoting of the leaf (12), in a central region thereof, to means for translational motion arranged so as to slide in a corresponding guide (13) associated with the upper stringer (14) of the frame (15) of the door; second pivoting means, whose axis is parallel with respect to the axis of the first pivoting means, for the articulation of two arms (16, 17), a first upper arm (16) and a second lower arm (17), which are both pivoted by means of a first end (21, 22) thereof to the frame (15) of the door or window proximate to a jamb (18) so as to form a second rotation axis (20), third pivoting means, which are formed by the second ends (23, 24) of the arms (16, 17), which are hinged to the leaf (12) so as to form a third rotation axis (26) that passes through the leaf (12) parallel to the first and second axes and in an intermediate position between the two first and second axes when the leaf is in the closed configuration. The second pivoting means comprise a pivot (27) arranged in a compartment (28) formed within the jamb (18), the pivot (27) joining the first ends (21, 22) of the arms (16, 17) and thus causing their joint rotation.The mechanism according to the invention facilitates and improves the installation of doors with rotary and translational motion.
Abstract:
A linkage member 3 is pivotally supported, through a first shaft 30, by an article 1 having an opening, is supported, through a second shaft 31, by a lid member 2, and includes a latch 32 engageable with a latch receiver 12 disposed in the article 1. The lid member 2 has an engageable end 201 disposed therein so as to be receivable into an engagement hole 34 formed in the linkage member 3 and further has a switching member 20 disposed therein so as to be movable to selectively set the engageable end 201 in an advanced position to place the engageable end in a most deepest position in the linkage member 3 through the engagement hole 34, in a retracted position to take the engageable end out of the engagement hole 34, and in an intermediate position between both of the advanced position and the retract position. When the engageable end 201 of the switching member 20 is set in the advanced position, the engageable end brings the latch 32 out of engagement with the latch receiver 12.
Abstract:
A folding panel assembly includes at least first and second, substantially rectangular panels, the first panel having first and second vertical ends, and the second panel having third and fourth vertical ends, the second and third vertical ends being hinged to one another about a hinge axis parallel thereto. An actuating system includes a substantially horizontal track, with a first pivot support for connection to the first panel, a carriage traversable along the track, with a second pivot support for connection to the second panel. The actuating system further includes a flexible drive element arranged parallel to the track and engaging the carriage for traversing it along the track. The actuating system employs an elongated connecting rod with a first longitudinal end pivotally connected to the carriage and a second, opposite longitudinal end pivotally connected to the first panel at a location adjacent to the second vertical end thereof. A line including the first and second longitudinal ends of the elongated connecting rod, in use, is excluded from becoming aligned with respect to the first panel in any position of the carriage along the track.
Abstract:
A container apparatus is provided in which a large space is not required in front of a housing for a door to be moved between a closed position and an open position.A housing 2 has an opening in a front surface 2a. A first attachment member 20 is attached to an inner surface of a side portion of the housing 2. A second attachment member 30 is attached to a rear surface 3a of a door 3 that opens and closes the opening of the housing 2. First, second and third links 41, 42, 43 are disposed between the first attachment member 20 and the second attachment member 30. The first attachment member 20, the second attachment member 30, and the first, second and third links 42, 43, 41 constitute a parallel link mechanism. This arrangement enables the door 3 to be translated.
