Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the respective vehicle pillars at the sides of the liftgate opening. Each drive unit includes a vertically oriented channel and a rack member that moves in the channel. The rack member comprises a rack bar and a plurality of rack links that are pivotally connected end-to-end. A transfer link is universally attached to the rack bar at one end and universally attached to the liftgate at the opposite end. The rack member is raised and lowered by a power unit that has a motor driven pinion gear that meshes with teeth of the rack bar and the rack links in succession. Raising and lowering the rack member opens and closes the liftgate via the transfer link.
Abstract:
A power operating apparatus for a vehicle door moveable between an opened position and a closed position, includes a drive mechanism provided at the inside of a vehicle body with respect to a door opening of the vehicle door to power move the vehicle door in an opening direction toward the opened position and in a closing direction toward the closed position, and a power-transmission mechanism mechanically linking the drive mechanism with the vehicle door to enable power transmission between the drive mechanism and the vehicle door. A through-opening in the body panel of the vehicle body so that the through-opening is arranged outside of the inner peripheral edge of the door opening. The power-transmission mechanism having at least a linkage portion capable of going into and out of the interior of the vehicle body. The linkage portion of the power-transmission mechanism is inserted into the through-opening, so that the locus of power movement of the linkage portion is generated outside of the inner peripheral edge of the door opening.
Abstract:
Motion imparting means, comprising first and second assemblies, to effect angular movement of a gate (10) mounted for pivoting motion about an upstanding axis (22). The first assembly includes drive means (65) comprising a magnetic body (15) that (a) has an outer cylindrical surface and radial end surfaces (b) is polarized axially of the cylindrical surface, and (c) has each radial end engaged by an associated pole plate (14,16) that extends outwardly beyond the body's cylindrical surface with its periphery spaced from that cylindrical surface. The second assembly comprises an engagement plate (53) to be attached to the pivoting member (10) and, in use, be engaged by the pole plates (14,16) and magnetically coupled thereto. A lever (34) is provided having the first assembly (65) mounted on one end, the lever being mounted by its opposite end for pivoting motion about an upstanding axis (32) spaced from the pivoting member's pivoting axis (22) and such that said drive means (65) can in use effect a magnetic drive coupling between the first and second assemblies. In one arrangement, one of the pole plates (16) is provided around its periphery with a plurality of mutually spaced protrusions (19) or depressions, and the engagement plate (53) is provided with correspondingly spaced depressions (21) or protrusions, the protrusions (19) of one said plate (16) in use engaging in the depressions (21) of the other said plate (53) to provide a positive inter-engagement between them that resists slippage across magnetically coupled surface portions of the drive means. In another arrangement (FIG. 6), each pole plate (14,16) is of generally disc-like form having a peripheral face of cylindrical form, a radial face directed away from the body, and between these two faces a chamfered face (54,56), and the engagement plate (63) has a surface (55) provided with an elongate groove of triangular or frusto-triangular cross-section providing inclined faces which are in use engaged by and magnetically coupled to the two said outwardly-directed chamfered faces (54,56) of the first assembly.
Abstract:
A drive unit for doors, especially doors having a non-rectilinear profile formed by wings (26, 26null, 24, 24null, 124, 126) comprises a motor (10) whose rotary shaft (20) engages with at least a bar or section (12, 14) connected to at least one of said wings. Said drive unit is located either on the roof or the external front of the lower basis or between the wings of an elevator car of story doors. In case of telescopic movement superposed wings, one of the wing is moved by the drive unit, and a transmission unit (100) transmits the rotation of a wing (124) to the other one (126).
Abstract:
This invention relates to a retractable screen system for a closure assembly and improvements thereof which allows the secure sliding and subsequent retraction of the screen from a operative position to a retracted position. The invention is preferably embodied in a window assembly but finds application also in large pivoting windows and patio doors.
Abstract:
A continuous roll of screen which may be payed out from said roll by an installer or manufacturer to a required predetermined window size, or alternatively patio door size, said screen comprising a free end which allows the installer to pay the screen off of the roll upon which the screen is accumulated course upon course, one end of said screen being disposed at the end of the courses accumulated on the roll from which the screening is payed off and the other end being a free end, said screen having side edges and preferably being manufactured from preferably vinyl-coated fiberglass, the edges of said screen having affixed thereto a generally preferably T-shaped key manufactured from a flexible material, for example polyvinyl chloride, which is affixed preferably by radio frequency welding (or RF welding) with the edges and preferably each of the edges, and in one embodiment at least one edge of said screen, wherein the vinyl coating provided on the screen melds with the polyvinyl chloride key to form a resilient anchor for the screen device within any screen roller assembly.
Abstract:
A hinged and sliding door assembly for vehicles includes a door surround defining an opening, a door configured for mating with the door surround, and a hinge-and-slide mechanism for supporting, and defining movement of, the door relative to the surround. The hinge-and-slide mechanism has an intermediate element connected to the door by a hinge structure which defines an axis of rotation about which the door rotates relative to the intermediate element. A slide mechanism, associated with the intermediate element and the surround, is configured to define a slide path of the intermediate element relative to the surround. The slide mechanism is further configured to support the intermediate element such that this axis maintains a substantially constant orientation relative to the surround, thereby supporting the door.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle frame and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear train, a rack and a cradle that are mounted on the bracket. The electric motor drives the rack via an the output gear of the gear train that has an axis. The rack slides in the cradle which is pivotally mounted on bracket so that cradle pivots about the axis of the output gear to hold the teeth of the rack in engagement with the teeth of the output gear to accommodate rocking movement of rack as it moves from a retracted position to an extended position. An arcuate track that is fixed to the vehicle body, and an arcuate link slides in the arcuate track. The arcuate link has an inboard end that is pivotally connected to an end of the rack and an outboard end that is pivotally connected to the liftgate.
Abstract:
A closure assembly includes a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly.
