The present disclosure relates to window regulators for use in motor vehicles and more particularly to an adjustable slider of the window regulator.
Vehicles may include power windows operated by a window lifter or window regulator. The window regulator is configured to support and carry a windowpane between a first position, e.g, a bottom position, disposed within a cavity of the door or other vehicle member, and a second position e.g, top position, engaged with an upper portion of the door or roof Window regulators used in vehicle doors that do not include an upper member that receives the windowpane may be referred to as a frameless window regulator assembly. Frameless window regulator assemblies are generally used in convertibles or other vehicles that include a windowpane that engages a roof rail.
According to one embodiment, an adjustable slider of a window regulator includes a base body configured to connect with a cable of the window regulator and a clamp-plate assembly having first and second jaws configured to clamp a windowpane therebetween. A hinge plate supports the clamp-plate assembly. A first adjustment mechanism pivotally connects the hinge plate to the base body such that the clamp-plate assembly and the binge plate are pivotal relative to the base body allowing a vertical angle of the clamp-plate assembly to be changed. The first adjustment mechanism is actuatable to move the hinge plate relative to the base body in a fore-and-aft direction allowing a fore-and-aft position of the clamp-plate assembly to be adjusted.
The adjustable slider may further include a second adjustment mechanism connected between the base body and the hinge plate. The second adjustment mechanism is actuatable to pivot the hinge plate relative to the base body allowing adjustment of the vertical angle. The base body may have an upper portion supporting the first adjustment mechanism and a lower portion connected to the second adjustment mechanism. The second adjustment mechanism may be operable to move a lower portion of the hinge plate towards and away from the lower portion of the base body to pivot the binge plate. The upper portion of the base body may define a hole, and the hinge plate may define a hoop, wherein the first adjustment mechanism includes an elongate member extending through the hole and the hoop to pivotally connect the hinge plate to the base body. The hole and the elongate member threadably engage.
According to one or more aspects of this disclosure, the base body may define a threaded hole and the first adjustment mechanism may include a threaded fastener disposed in the hole, wherein rotation of the fastener moves the hinge plate relative to the base body in the fore-and-aft direction. For example, the hinge plate has a pair of loops that are spaced apart and the threaded hole is disposed between the loops and the fastener extends through the loops.
According to one or more further aspects of this disclosure, the base body defines a through hole that is elongated in the fore-and-aft direction, and further includes a fastener extending through the first jaw, the second jaw, and the hinge plate and disposed within the through hole.
According to another embodiment, an adjustable slider includes a base body configured to connect with a cable of a window regulator, a clamp-plate assembly configured to support a windowpane, and a first adjustment mechanism configured to move the clamp-plate assembly relative to the base body in a fore-and-aft direction.
According to yet another embodiment, a window regulator includes a guide rail, a cable supported on the guide rail, an actuator operably coupled to the cable and configured to move the cable relative to the guide rail, and a slider fixed on the cable and slidably connected to the guide rail. The slider includes a base body configured to connect with the cable, a clamp-plate assembly configured to support a windowpane, and a first adjustment mechanism configured to move the clamp-plate assembly relative to the base body in a fore-and-aft direction.

Window regulators may include one or more guide rails and a slider that may move or translate along the guide rails to adjust a windowpane. Frameless window regulators or window regulators configured to move a windowpane that does not engage an upper door rail or member may present a number of challenges that may not be associated with conventional window regulators. For example, the relative angular position of the windowpane may vary with respect to one or more mating features, such as a roof rail, a seal, or both that are each configured to receive the windowpane when the windowpane is in a top or uppermost position. If the angular position of the windowpane is greater than a predetermined tolerance, the windowpane and the seal may not form a sufficient seal.
Generally, one manufacturer may assemble and ship the window regulator to a vehicle integrator or original equipment manufacturer (OEM) that assembles the windowpane to the window regulator and the window regulator and glass to the associated vehicle component, e.g., door. Because an insufficient seal or fit between the windowpane and the mating seal or frame member may not be discovered until after the window regulator is shipped and assembled to the vehicle, it may be desirable to provide one or more adjustment mechanisms to adjust the vertical angle of the windowpane as well as the fore-and-aft position. This adjustment(s) may be made by the manufacturer of the window regulator, the OEM, or both. The OEM may inform the window regulator manufacturer of the desired angle or required adjustment so that the manufacturer may set the set these parameters of the slider prior to shipping the window regulators.
Referring to
An actuator 34, such as an electric motor, drives the cables to adjust the sliders 32 up and down along the guide rails 26. The sliders 32 connect to and directly support the windowpane 22. The windowpane 22 is opened and closed within a vehicle by operating the electric motor. Operating the electric motor 34 in a first direction causes the sliders 32 to move downwardly to open the window, and operating the electric motor 34 and a second direction causes the sliders to move upwardly to close the window as is known in the art.
Referring to
A first adjustment mechanism 46 is configured to change the angle or pitch 47 of the clamp-plate assembly 44 relative to the vertical axis to adjust the pitch of the windowpane to ensure proper fit in the vehicle. This may be referred to herein as the “vertical angle.” The clamp-assembly 44 may be pivotally connected to the base body 40 by a hinge plate 52. The hinge plate 52 may include loops 54 that are pivotally attached to an upper portion 56 of the base body 40 by a pin assembly 58. The pin assembly 58 includes an elongate member 60 that extends through the loops 54 and a hole 55 defined through the upper portion 56. Pivoting of the hinge plate 52 about the elongate member 60 pivots the clamp-plate assembly 44 to adjust the vertical angle 47.
The first adjustment mechanism 46, according to one or more embodiments, may include a fastener assembly 62 located at a lower portion of the slider 32. The fastener assembly 62 includes a shoulder 66 that secures to a lower portion 67 of the hinge plate 52. For example, the shoulder 66 may define a groove 69 that receives the lower portion 67 therein. The shoulder 66 is supported on (or integral with) an adjustment screw 68 that is threadably received through a threaded hole 71 of the base body 40 in the illustrated example. Rotation of the adjustment screw 68 moves the lower portion of the hinge plate 52 towards or away from the base body 40 and pivots the jaws 45, 48 about the elongate member 60. Rotation of the screw 68 in a first direction moves the lower portion 67 towards the base body 40, and rotation of the screw 68 and a second direction moves the lower portion 67 away from the base body 40.
The adjustment mechanism 46 is not limited to the illustrated embodiment. For example, Applicant's co-pending application Ser. No. 16/432,044 (filed Jun. 5, 2019), the contents of which are hereby incorporated by reference herein in their entirety, describes another adjustment mechanism that may be used to adjust the pitch of the jaws.
The slider 32 includes a second adjustment mechanism 70 that allows the windowpane to be adjusted in the fore-and-aft direction of the vehicle. The second adjustment mechanism 70 is configured to move the clamp-plate assembly 44 relative to the base body 40 in the fore-and-aft direction.
The second adjustment mechanism 70 may include the elongate member 60. In one or more embodiments, the elongate member 60 is a threaded fastener having a shank 72 and a head 74. The shank 72 may define threads (at least partially), and the head 74 may define a receptacle configured to receive a tool such as an Allen key. The hole 55 may define female threads that engage with the male threads of the fastener 60. The shank 72 extends through the loops 54 and the hole 55. The loops 54 are not threaded. A nut 76 is threadably received on the distal end of the threaded shank 72. The nut 76 is tightened so that the loops 54 are squeezed between the head 74 and the nut 76. This secures the hinge plate 52 to the fastener 60 so that fore-and-aft movement of the fastener 60 moves the hinge plate 52 and consequently moves the windowpane fore-and-aft relative to the guide rails. Rotation of the fastener 60 in a first direction moves the head 74 towards the hole 55 to move the clamp-plate assembly 44 (and the windowpane) to the left in
