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 retrofit conversion kit for facilitating the conversion of a door operating apparatus conventionally mounted above the door, to a position mounted and anchored underground for operating a swinging door therefrom. The conversion to an anchored underground position is facilitated by incorporating positional adjustment mechanisms covering any or all possible adjustment dimensions.
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 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 multi-part drive shaft for a transit vehicle door comprises an upper drive shaft connected to a door operating mechanism and having a door panel operating arm extending therefrom, a lower drive shaft journaled for rotation, a door panel operating arm extending therefrom and a flexible drive shaft secured at one end to the upper drive shaft and at the other end to the lower drive shaft. Rotation of the upper drive shaft will transfer torque to the lower drive shaft at the same angular speed.
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.
Abstract:
A door operator having a door hanger comprising a pair of double trolley assemblies disposed for linear movement within a hanger rail, wherein each trolley assembly further comprises two rollers mounted substantially opposite one another and engaging roller cavities within said hanger rail. Said door hanger is integrated with the drive system or is mounted independently of the drive system for replacement of the door hanger of the prior art or in new application requiring such independency between the door hanger and drive system.
Abstract:
A power-operated system for actuating the rear doors or liftgates of motor vehicles includes a strut assembly having two struts, each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut is connected to a powered rotating arm. To open the door, the rotating arms change the angular orientation of the struts such that they have a substantial mechanical advantage. In this position, the force provided by the struts overcomes the weight bias of the door, thus opening the door. To close the door, the rotating arms change the angular orientation of the struts such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore causing the door to fall closed under its own weight bias. A control system for controlling the power-operated system is also disclosed.
Abstract:
A reinforcing block for a closure tilt latch, comprising a body fastened in a closure track fastened to a frame, said body having a top and bottom and having a locking detent extending therein said locking detent providing a vertical face extending toward said top of said body from intermediate said top and bottom, the tilt latch being compatible with the vertical face of said locking detent, wherein when said latch engages said detent said block provides a reinforcement path to the closure frame to strengthen the loading capability of said closure and to reduce the risk of the latch from disengaging said track under loading which track would be subject to distortion had the block not been utilized.
