The present disclosure relates to a slider for supporting a window pane for a window regulator for use in a motor vehicle.
Vehicles may include a mechanism such has a window lifter or window regulator configured to support and carry a window pane 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 window pane 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 window pane that engages a roof rail.
According to one embodiment, an adjustable slider configured to support and carry a window pane, is provided. The adjustable slider may include a first jaw, an engagement member, and an adjustment mechanism. The first jaw may extend in a first direction and include a first face. The first face may include a ramped surface that may extend obliquely with respect to the first direction. The engagement member may be configured to be disposed between the window pane and the first jaw. The adjustment mechanism may include an adjustment member that may be configured to rotate about a first rotational axis. The adjustment mechanism may also include a translatable member that may be coupled to the engagement member and configured to translate about the first rotational axis such that rotation of the adjustment member moves the engagement member along the ramped surface of the first jaw.
The adjustment member may be a threaded member including a plurality of first threads and the translatable member may include a plurality of second threads. As the threaded member is rotated, the second plurality of threads engage the first plurality of threads.
The translatable member may be a spindle nut.
The first jaw may include a second face that may oppose the first face. The second face may include a cage configured to house the spindle nut. The first jaw may include a second face that may oppose the first face. The engagement member may include a flange that may extend in a direction that may be parallel to the first side. The flange may engage the spindle nut.
The flange may define a notch provided with an inner periphery. The inner periphery of the notch may be configured to engage the spindle nut.
According to another embodiment, an adjustable slider configured to support and carry a window pane is provided. The adjustable slider may include a base member, an engagement member, and an adjustment mechanism. The base member may extend in a first direction. The engagement member may be configured to be disposed between the window pane and the base member. The adjustment mechanism may include a first adjustment member that may extend in the first direction and may be coupled to the base member. The adjustment mechanism may include a second adjustment member that may extend in a second direction, that may be substantially transverse to the first direction and may be configured to engage the first adjustment member. The adjustment member may also include a translatable member that may be coupled to the engagement member and the first adjustment member. Rotation of the first adjustment member may translate the translatable member along the first adjustment member to move the engagement member along the base member.
The base member may define a receptacle configured to receive at least a portion of the second adjustment member.
The receptacle may be an aperture and the second adjustment member may be configured to rotate in a non-translatable manner within the aperture.
The first adjustment member may include a first head and the second adjustment member may include a second head. The second head may be configured to engage the first head such that as the second head is rotated, the first adjustment member rotates.
The first head of the first adjustment member may be castellated.
The first head may include a plurality of first protrusions and a plurality of first recessed portions. Each of the first recessed portions may be disposed between a pair of protrusions of the plurality of first protrusions.
The second head may include a plurality of second protrusions and a plurality of second recessed portions. Each of the second recessed portions may be disposed between a pair of second protrusions of the plurality of second protrusions.
The base member may include a ramped surface that may extend obliquely with respect to the first direction.
The engagement member may be configured to move between a first position and a second position. When the engagement member is in the first position, a surface of the window pane and a surface of the base member may define a first angle. When the engagement member is in the second position, the surface of the window and the surface of the base member may define a second angle. The second angle may be different than the first angle.
According to yet another embodiment, an adjustable slider configured to support and carry a window pane is provided. The adjustable slider may include a first jaw, an engagement member, a sleeve, and a glass fixation bolt. The first jaw may extend in a first direction and include a first face defining an aperture.

Window regulators may include one or more guide rails and a slider that may move or translate along the guide rails to adjust a window pane. Frameless window regulators or window regulators configured to move a window pane 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 window pane 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 window pane when the window pane is in a top or uppermost position. If the angular position of the window pane is greater than a predetermined tolerance, the window pane and the seal may not form a sufficient seal.
Because of tolerances and part quality, the angular position of the window pane may vary. Generally, one manufacturer may assemble and ship the window regulator to a vehicle integrator or original equipment manufacturer (OEM) that assembles the window pane 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 window pane 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 an adjustment mechanism to adjust the angular position of the window pane. This adjustment 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 angle before shipping the window regulators.

Referring generally to the figures, the adjustable slider 108 according to one or more embodiments is provided. The adjustable slider 108 may include a first jaw 110 that may extend in a first direction 109. The first jaw 110 includes a first face 111 that may include a ramped surface 112 that may extend in an oblique direction with respect to the first direction 109. An engagement member 116 may be coupled to the first jaw 110 and to an adjustment mechanism 118. The adjustment mechanism 118 may include an adjustment member 120, that may extend in the first direction 109, and a translatable member 122 that may be coupled to the engagement member 116. The adjustment member 120 may be configured to rotate about a first rotational axis 124 such that as the adjustment member 120 rotates, the translatable member 122 and the engagement member 116 moves along the ramped surface 112.
The adjustment member 120 may be a threaded fastener provided with a plurality of first threads 126 that may be configured to engage a plurality of second threads (not shown) formed by an inner portion of the translatable member 122. The translatable member 122 may be a spindle nut that may engage the plurality of first threads 126 so that the adjustment member 120 rotates but does not translate, e.g., move vertically.
In one or more embodiments, the first jaw 110 may include a second face 128 that opposes the first face 111. The second face 128 may include a cage 130 that may be configured to receive and house the translatable member 122. A first side 132 of the first jaw 110 may connect the first face 111 and the second face 128 and extend in a direction that is transverse to the first direction 109. The engagement member 116 may be provided with a flange 134 that may be arranged parallel to the first side 132. The flange 134 may define a notch 136 that may be configured to engage the translatable member 122. That notch 136 may be sized to engage the translatable member 122 in a press-fit manner so that the notch 136 may be selectively detachable from the translatable member 122.
The engagement member 116 may be configured to move along the first jaw 110 between a first position and a second position. When the engagement member 116 is in the first position, a surface 140 of the window pane W and a surface of the first jaw 110, such as the first face 111, may define a first angle α. When the engagement member 116 is in the second position, the surface 140 of the window pane W and a surface of the first jaw 110, such as the first face 111, may define a second angle β. Altering the angles of the window pane W with respect to the first jaw may provide better sealing or mating between the window pane W and the mating vehicle component.
In one or more embodiments, an adjustable slider 200 may be provided with an adjustment mechanism 202 that may include a pair of adjustment members. For example, the first adjustment member 204 may be coupled to a base member 206 and extend in a first direction 208. A second adjustment member 210 may extend in a second direction 212 that may be substantially transverse to the first direction 208. The first adjustment member 204 may include a first head 214 and the second adjustment member 210 may include a second head 216. The first head 214 and the second head 216 may be arranged so that they engage each other. For example, as the first adjustment member 210 rotates, the first head 214 may engage and rotate the second head 216. As another example, the first head 214 may engage the second head 216 to prevent unintended rotation of the second adjustment member 210 and vice-versa.
The first head 214 and the second head 216 may each be castellated. For example, the first head 214 may include a plurality of first protrusions 218 and a plurality of first recessed portions 220. One of the plurality of first recessed portions 220 may be disposed between a pair of protrusions of the plurality of first protrusions. The second head 216 may include a plurality of second protrusions 222 and a plurality of second recessed portions 224. One of the plurality of second recessed portions 224 may be disposed between a pair of protrusions of the plurality of second protrusions 222. As another example, the protrusions and recessed portions may be provided on another portion of the adjustment members 204, 210, such as a shaft that extends from the head.
The first jaw 110 may include a receptacle, such as an aperture 226. The aperture 226 may receive a distal end 228 of the second adjustment member 210. The second adjustment member 210 may have an outer diameter and the aperture 226 may have inner diameter, larger than the outer diameter so the distal end 228 may rotate within the aperture 226.
The adjustable slider 108 may include a sleeve 142 that may receive a glass fixation member 144. The glass fixation member 144 and the sleeve 142 may each be configured move between a pre-assembled position and an assembled position. As one example, the window regulator 100 and adjustable slider may be sent to an assembler, such as an OEM, with the sleeve 142 and the glass fixation member 144 in the pre-assembled position. The assembler may insert the window pane W into the adjustable slider 108 and move the glass fixation member 144 and the sleeve 142 to an assembled position to secure the window pane W to the slider 108.
The sleeve 142 may include an outer periphery 146 and an inner periphery 148. The outer periphery may include a number of protrusions 150 that may engage an inner periphery of an aperture, such as a glass attachment aperture 152 defined by the first jaw 110. The inner periphery 148 may include a number of protrusions 149 that may be configured to engage the glass fixation member 144. In the pre-assembled position, a first portion 154 of the glass fixation member 144 may engage the inner periphery 148 and one or more protrusions 149 in a press-fit manner.
