DETAILED DESCRIPTION
[0035]
[0036] An elongated gutter 46 having a gutter top surface 45 is provided below the first and second tab end surfaces 40, 44. The gutter 46, along with the first resilient tab 38 and second resilient tab 42, extend longitudinally along a first axis 50 between the first end wall 34 and the second end wall 36, wherein the combination of the first and second tab end surfaces 40, 44 and the gutter top surface 45, form a ball track 48. The ball track 48 is configured to receive the head 18 of the ball stud 16 and allow longitudinal movement of the head 18 along the first axis 50, while restricting movement along a second axis 52 (
[0037] The first and second resilient tabs 38, 42 secure the head 18 of the ball stud 16 when it is inserted into the ball track 48. While it has been found effective to use a configuration of the resilient tabs similar to those disclosed in U.S. Pat. No. 9,140,294, for a non-sliding configuration to anchor a ball stud to a single point, other shapes and designs of resilient tabs could be used for the interaction between the ball channel 12 and the mounting panel 14, as described below, which provides longitudinal movement of the ball stud 16 as well as significant resistance to flexing, so as to provide a high degree of pull out force resistance (resistance to an extraction force of the head 18 from the ball track 48).
[0038] The ball channel 12 further includes a flange 53 that extends partially, substantially, or completely around the outer portion of the ball channel 12. The flange 53 includes a flange wall 54. In at least some embodiments, the flange wall 54 is in part or in whole, tapered outward as it extends downward toward the channel bottom 22. Further, in at least some embodiments, the flange wall 54 includes one or more non-tapered portions. In at least some embodiments, the flange wall 54 includes a pivot wall portion 56 that extends below the latching end 60, which in at least some embodiments, is not tapered (extends vertically between the channel top 20 and channel bottom 22) or is less tapered than the other portions of the flange wall 54. Further, in some embodiments, the flange wall 54 is not tapered at all, but provides an abutment with the mounting panel 14, as discussed in detail below, and additionally in other embodiments, the flange wall 54 can include other protruding shapes, such as a right-angle step. The pivot wall portion 56 can assist with installation of the ball channel 12 to the mounting panel 14 as discussed below.
[0039] The ball channel 12 further includes a neck wall 58 that extends from the channel top 20 to the flange 53. The neck wall 58 can include a latching end 60, which can be positioned adjacent the front end wall 24. A notch 62 is formed at the intersection of the pivot wall portion 56 and the latching end 60. In addition, a latching fastener 64 can be provided extending from or adjacent to the rear end wall 26, wherein the latching fastener 64 can include one of various fastening configurations, such as a snap-fit latch. In at least some embodiments, the latching fastener 64 includes a ramped snap end portion 80 and a snap engagement ledge 81 situated below the snap end portion for engagement with the mounting panel 14 as discussed below.
[0040] Referring to
[0041] Referring to
[0042]
[0043] The angled positioning of the first resilient tab 38 and second resilient tab 42 provide a resistive force directed towards the first axis 50, resulting in a pull out force resistance against the head 18 when an extraction force is applied to remove the ball stud from the ball channel 12. In addition, the wedged abutment of the flange wall 54 with the receiving wall 70 serves to further enhance the resistive force directed towards the first axis 50. More particularly, an extraction force is imparted from the head 18 to the first and second tab end surfaces 40, 44, such that the flange wall 54 is pushed outwards as it resists the force of the first and second resilient tabs 38, 42. The addition of the receiving wall 70 being in wedged abutment with the flange wall 54 serves to limit the outward flexing of the flange wall 54, thereby requiring a higher extraction force to remove the head 18 than would be required without the wedged abutment from the receiving wall 70. Further, the aforementioned configuration allows for an increased pull out force resistance while maintaining a lower insertion force. In contrast, merely increasing the rigidity of the first and second resilient tabs 38, 42 and the surrounding flange wall 54 without the wedged abutment provided by the mounting panel 14, would increase the pull out force resistance, but would also increase the required insertion force, as well as reduce the plasticity of the components, resulting in difficult installations and higher insertion damage rates.
[0044] Further in other embodiments, such as provided in
[0045] Referring now to
[0046] The upper flange wall 55 extends between the neck wall 58 and the center flange wall 51. The lower flange wall 57 extends downward from the center flange wall 51 towards the channel bottom 22 and can be offset from the upper flange wall 55. In at least some embodiments, the upper flange wall 55 and the lower flange wall 57 extend substantially vertically (parallel to the second axis 52) and the center flange wall 51 is angled with respect to the second axis 52 (to provide a tapered center flange wall 51), while in some other embodiments, the upper flange wall 55, lower flange wall 57, and the center flange wall 51can have varied angles relative to the second axis 52, for example the upper flange wall 55 and/or the lower flange wall 57 can be tapered and/or vertically offset from one another, while the center flange wall 51 can extend vertically, or any other such combination therebetween. Further, in at least some embodiments, the upper flange wall 55 and the lower flange wall 57 are parallel to each other and non-parallel with the center flange wall 51.
[0047] The ball channel 12 includes the gutter 46, which in at least some embodiments, is substantially continuous or continuous, such as shown in
[0048] Referring to
[0049] The portions of the receiving wall 70 can take various forms. In at least some embodiments, the upper receiving wall 73 and the lower receiving wall 75 extend substantially vertically (parallel to the second axis 52) and the center receiving wall 71 is angled with respect to the second axis 52 (to provide a tapered center receiving wall 71), while in some other embodiments, the upper receiving wall 73, lower receiving wall 75, and center receiving wall 71 can have varied angles relative to the second axis 52, for example the upper receiving wall 73 and/or the lower receiving wall 75 can be tapered and/or vertically offset from one another, while the center receiving wall 71 extends vertically, or any other such combination therebetween. Although the portions of the receiving wall 70 can take many forms, in at least some embodiments, the receiving wall 70 is shaped and sized to matingly receive and engage the flange wall 54. As such, the angled surfaces of the flange wall 54 and receiving wall 70 shall in at least some embodiments, include complementary angles (such as shown in exemplary
[0050] The flange wall 54of the ball channel 12 is configured to be complementarily engaged, in part or in whole, with the receiving wall 70 of the mounting panel 14. As discussed above with regard to the flange wall 54 and receiving wall 70, when the ball channel 12 is secured to the mounting panel 14, the receiving wall 70 serves to provide additional support to the first and second resilient tabs 38, 42 via the flange wall 54, during the application of an extraction force imparted from the head 18 to the first tab end surface 40 and second tab end surface 44. The additional support increases the pull out resistance provided by ball channel assembly 10, and does so without significantly increasing the insertion force of the head 18.
[0051] The installation of the ball channel 12 into the mounting panel 14 is similar to the procedure as shown and described above with reference to
[0052] The ball channel can vary in shape, thickness and material of construction as required for a particular application. The mounting panel and mounting panel opening can have different shapes and geometries, typically as defined by the manufacturer of the part into which the ball channel will fit, for example, square, rectangular, etc. In at least some embodiments, the head is spherical and the first and second tab end surfaces, as well as the gutter, are curved to matingly receive and/or engage the head, while in other embodiments, other shapes can be utilized to accordingly receive and/or engage a non-spherical head. In addition, the aforementioned components can be comprised of one or more different materials, such as plastic, metal, etc., either alone or in combination.
[0053] The mounting panel can be a singular component, or formed or otherwise secured to any one of numerous assemblies, substrates, device, etc. In at least some embodiments, the mounting panel is formed as a portion of a headlamp assembly of an automobile. In at least some embodiments, a headlamp assembly comprised of multiple mounting panels can be utilized with associated ball channels to secure the headlamp assembly to an automobile in an adjustable manner. Further, the ball channel assembly can be used in a multitude of non-automotive lamp situations where similar performance capabilities are required.

Rather, it is recognized that modifications may be made by one of skill in the art of the invention without departing from the spirit or intent of the invention and, therefore, the invention is to be taken as including all reasonable equivalents to the subject matter of the appended claims and the description of the invention herein. It shall be understood that the term plurality can represent one or more of an element.
