DESCRIPTION

[0014] Exemplary features of the present disclosure will now be described through reference to the various figures, wherein like elements are designated by like reference numerals in the various views. Referring now to the drawings, FIG. 1 is a view of an exemplary door handle assembly 10 without a cover so as to illustrate various internal components. As shown, the door handle assembly 10 incorporates an outer support component 12 in the form of a plate housed at the interior of a surrounding mating component 14. As will be appreciated, the mating component 14 includes an arrangement of perimeter attachment openings 16 adapted to receive male connectors such as pins, male fasteners or the like (not shown) for connection to a backing structure in a manner as will be well known to those of skill in the art.

[0015] The outer support component 12 is substantially planar and provides a protective structural support covering for internal components 18 of the door handle assembly 10 (FIG. 4) including an operative hooking latch 20 and complementary wire 22 which operate in a well known manner during operation of the door handle assembly 10.

[0016] In the illustrated exemplary construction, the outer support component 12 includes a substantially flat exterior face 24 with a plurality of cutouts 26 disposed therein for access to the underlying operative components of the door handle assembly 10. By way of example only, and not limitation, the outer support component may be formed as a unitary structure from a suitable plastic material such as acetal resin, Nylon 6, polyester or the like using techniques such as injection molding and the like. However, it is also contemplated that other structural materials such as metals, composites, and the like may likewise be utilized if desired.

[0017] In the illustrated exemplary construction, the outer support component 12 includes a transverse passageway 32 extending across the thickness dimension of the outer support component 12 (FIG. 2). The transverse passageway 32 defines a female opening for acceptance and threaded retention of a dual sided adjustable male fastener 40 as best seen in FIGS. 2 and 3. In accordance with the present disclosure, the dual sided adjustable male fastener 40 is used in conjunction with the transverse passageway 32 to establish and maintain a proper depth setting for the outer support component 12 relative to the surrounding mating component 14. Such a proper depth setting facilitates proper function while avoiding damage that may result from excessive compression.

[0018] As best illustrated in FIG. 2, the dual sided adjustable male fastener 40 may include a proximal head 42 of enhanced diameter having a proximal tool engagement indenture 44 adapted to engage a driver 46 such as a torx driver, star driver or the like as shown in FIG. 3. Of course, other forms of indentures adapted to engage other drivers may likewise be used if desired.

[0019] As illustrated, the dual sided adjustable male fastener 40 may also include a distal nipple 48 of reduced diameter having a distal tool engagement indenture 50 adapted to engage a driver 52 such as a flat head screw driver or the like as shown in FIG. 4. Of course, other forms of indentures adapted to engage other drivers may likewise be used if desired.

[0020] In the illustrated exemplary construction, the dual sided adjustable male fastener 40 further includes a threaded shank portion 56 disposed between the proximal head 42 and the distal nipple 48. As shown the threaded shank portion 56 has an effective diameter which is less than the diameter of the proximal head 42 and greater than the diameter of the distal nipple 48.

[0021] As best illustrated through joint reference to FIGS. 1-3, at a preliminary stage of assembly, the dual sided adjustable male fastener 40 may be matedly inserted in threaded relation into the transverse passageway 32 from a position on the back of the outer support component 12 using the driver 46. As shown, the dual sided adjustable male fastener 40 is advanced along an axis line 58 in coaxial relation to transverse passageway 32. As best seen in FIG. 2, at the location of insertion of the dual sided adjustable male fastener 40, the transverse passageway 32 may be surrounded by a substantially annular raised boss 60 which projects rearwardly away from a hub 62 at the back of the outer support component 12 in substantially coaxial relation to passageway 32 and axis line 58.

[0022] As shown in FIG. 3, at the preliminary stage of assembly, the dual sided adjustable male fastener 40 may be inserted into the passageway 32 to a depth such that the raised boss 60 engages the proximal head 42 and thereby blocks further insertion. In this regard, the interface between the raised boss 60 and the proximal head 42 will prevent the dual sided adjustable male fastener 40 from being over driven into the raised boss 60. As illustrated, the dual sided adjustable male fastener 40 has an operative length such that at least a portion of the distal nipple 48 projects outwardly from the transverse passageway 32 when the dual sided adjustable male fastener 40 is fully inserted so as to be in contacting relation to the raised boss 60.

[0023] In accordance with one exemplary practice, after the dual sided adjustable male fastener 40 is assembled into the transverse passageway 32, the outer support component 12 may be assembled to the proper location relative to the mating component 14. In this regard, at the point of vehicle assembly, a sheet metal pocket 64 may be positioned between the perimeter of the outer support component 12 and the mating component 14 by an assembly tool to establish the desired gap between outer support component 12 and mating component 14. Simultaneously, the same tool may set the depth of the exterior face 24 of the outer support component 12 to be substantially flush relative to the mating component 14.

[0024] As will be appreciated, after the outer support component 12 is assembled to the relative to the mating component 14, it may be desirable to engage in a final adjustment to lock in the desired depth of the outer support component 12. Referring jointly to FIGS. 1, 4 and 5, it may be seen that such final adjustment may be accomplished by applying torque to the dual sided adjustable male fastener 40 from a position at the exterior face 24. By way of example only, and not limitation, such torque may be applied by use of a driver 52 such as a flat head screw driver or the like engaging the distal tool engagement indenture 50 at the distal nipple 48.

[0025] As best illustrated through reference to FIGS. 3-5, it may be seen that at the outwardly projecting exterior face 24 of the outer support component 12, the passageway 32 may be surrounded by a cavity 66 defining a depression with a substantially flat, annular base 68 extending radially outboard from the passageway 32 in substantially coaxial relation to passageway 32 and axis line 58. As shown in FIG. 5, the diameter of the cavity 66 may be set to accept insertion of the driver 52 such that the dual sided adjustable male fastener 40 may be adjusted by application of torque from the position in FIG. 3 towards the position shown in FIG. 5. As will be appreciated, in the position of FIG. 5, the terminal end of distal nipple 48 will be substantially flush with the surrounding annular base 68. Moreover, the annular base 68 will limit the degree of movement of the dual sided adjustable male fastener 40 by blocking the driver 52 once the distal nipple 48 has reached the flush position.

[0026] In the illustrated exemplary construction, the door handle assembly 10 may include a dome spring 70 (FIG. 4) or other resilient support positioned in opposing relation to the raised boss 60. Thus, as the dual sided adjustable male fastener 40 is driven inwardly, the proximal head 42 will engage dome spring 70 which will provide underlying support. As will be appreciated, this underlying support aids in preventing the dual sided adjustable male fastener 40 from moving rearwardly in the passageway due to vibration during use.

[0027] In the illustrated exemplary construction, the dome spring 70 is provided with an underlying support 72 which limits deflection. Accordingly, as the dual sided adjustable male fastener 40 is moved inwardly, increasing resistance is encountered until no further inward movement can be accommodated.

[0028] As will be understood, once the dual sided adjustable male fastener 40 can no longer be advanced inwardly due to blockage by the dome spring 70, the application of further torque will cause the outer support component 12 to be lifted upwardly in the manner of an Archimedes screw motion. Such upward motion can take place until the annular base 68 ultimately engages the driver 52 in the orientation shown in FIG. 5. As will be appreciated, this system facilitates extremely fine depth adjustment in the order of about 2 mm. Of course, adjustment can also be ceased before this position is reached if the desired orientation has been achieved.

[0029] Once the handle gap is established, and a flush orientation is achieved, a decorative cap (not shown) may be snapped onto the door handle assembly 10 and the door handle assembly 10 is then ready to be operated. In this condition, the outer support component 12 will provide the desired internal support while remaining flush with the surrounding mating component 14.
