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 hinge mechanism having a vehicle bracket that includes a pawl engagement member extending therefrom. A horizontally-rotating swing arm is rotatably coupled with the vehicle bracket. The hinge mechanism includes a pawl with an engagement portion and an abutment portion. The pawl is connected with the swing arm and operable between an engaged position and a disengaged position. A door bracket is rotatably coupled with the swing arm. A lever actuation member extends from the door bracket and is aligned to engage the abutment portion of the pawl.
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.
Abstract:
A stabilizing assembly includes a retaining device settled between a drawable carrier and a cabinet body for preventing the drawable carrier from swinging in sliding. The retaining device includes two rails fixed to two opposite laterals of the drawable carrier. Each of the rails has a rack. Two gears engaging with the racks are connected by a rod and rotate simultaneously. Two bushes at two ends of the rod are received in supporting seats that are fixed on the cabinet body or the drawable carrier and allowed to shift vertically. Two stop portions, as a stop unit, each extending from the rail toward a side of the rod opposite to another side of the rod facing the rack on the rail are closely adjacent to the retained portions so that the bushes are retained and stopped by the stop unit, and disengagement between the racks and the gears is prevented.
Abstract:
A hinge assembly for vertical-movement doors comprises two articulated-quadrilateral hinges each including a first plate designed to be fastened to the furniture flanks, a second plate designed to be fastened to the door and two superposed arms pivotally mounted between the plates to form the quadrilateral connecting-rods. The assembly comprises brackets for removable fastening of the bar ends to the hinges, where the brackets can be alternatively mounted at two different fastening seats present at locations spaced apart from each other, along the upper arm of each hinge.
Abstract:
A hinge assembly for use with a door, in particular, an aircraft door, that enables the door to remain substantially parallel to the fuselage of the aircraft when the door is open and closed. The hinge assembly includes a door support assembly that couples to the door, and a hinge arm assembly. The hinge arm assembly includes a first gear assembly that couples to the fuselage, a second gear assembly that couples the hinge arm assembly to the door support assembly, and a linkage assembly coupled to the first and second gear assemblies. The first and second gear assemblies and linkage assembly cooperate to move the door support assembly and hinge arm assembly with respect to each other.
Abstract:
An opening/closing device (1) is described in the form of an articulated pentalateral with two centres of rotation (17,18) connected to each other by means of gears, able to open/close a flap door (2) of an item of furniture (3) and comprising a support (4) to which are hinged at least a first and a second arm (5, 6) coupled to each other by means of two toothed areas (7, 8) formed on the outer surfaces of the ends of the first arm (5) and of the second arm (6), which are hinged to the support (4) by means of pivots which form the above centres of rotation (17, 18). One end of the element (9) which carries the flap door (2) is hinged to the other end of the second arm (6) by means of a pivot forming the axis of rotation (11) of the flap door (2): on opening of the flap door (2) the second arm (6) is made to rotate towards the outside of the item of furniture (3) by rotation of the first arm (5), shifting the axis of rotation (11) of the flap door (2) towards the outside of the item of furniture (3) and allowing opening thereof even if the flap door (2), when closed, is superimposed on the upper part of the frame of the item of furniture (3).
Abstract:
A folding and spreading system for a half spread folding comprises an upper and a lower guider for making the folding door move in a close or open direction; a first wire guider provided at the depth portion of each door leaf in a predetermined distance from a neighboring first wire guider, and a second wire guider installed coaxially to the first wire guider; a folding motor and a spreading motor provided at both end frames of the folding door, respectively, and having a reel at each rotational shaft of each motor; and a winding wire and a releasing wire extended diagonally through each of the wire guiders of each door leaf, respective end of the wires connected to the wire guider and to the reel of the motor, respectively, in order to fold and spread the adjacent two door leaves around the hinge.
Abstract:
A pocket door system for the suspension of a pocket door within an entertainment cabinet or the like is shown with a rack and pinion guide associated with each pocket door slide and a synchronization shaft for transmittal of the actuation of one pocket door slide to the other, and where the installation of the pocket door slide and rack and pinion guide are integral to each other and also provide an improved alignment methods.
