[0055] With reference to FIGS. 1-3, an assembly of at least one driveway reflector holder 19 and an installation tool 10 for inserting the reflector holder 19 into a ground surface 21 is shown in accordance with one embodiment or aspect of the present disclosure. The reflector holder 19 includes a hollow sleeve body 18 extending from an upper end 72 to a lower end 74, a washer 17 disposed proximate the upper end 72, and at least one retention feature 20 disposed on an exterior of the hollow sleeve body 18. According to an example, both the upper end 72 and lower end 74 of the hollow sleeve body 18 are open. The installation tool 10 may be in the form of a driver stake 10 that may be removably receivable within the hollow sleeve body 18 of the reflector holder 19. The installation tool 10 includes an elongated body 76 extending from an upper end 78 to a lower end 80. A head 33 is defined at the upper end 78 of the elongated body 76, and a tapered or pointed tip 16 is defined at the lower end 80 of the elongated body 76.

[0056] As shown, the installation tool 10 is configured to extend through the hollow sleeve body 18 of the reflector holder 19 with the head 33 being positioned above the upper end 72 of the hollow sleeve body 18 and the tapered tip 16 being positioned below the lower end of the hollow sleeve body 18. The installation tool 10 is inserted into the hollow sleeve body 18 and then driven into the ground surface 21 to insert and affix the reflector holder 19 into the ground surface 21, as will be described in more detail below. Then the installation tool 10 is removed from the reflector holder 19 and the ground surface 21 after the reflector holder 19 has been inserted and affixed into the ground surface 21. The hollow sleeve body 18 of the at least one reflector holder 19 is then capable of removably receiving a driveway reflector 23 in the hollow sleeve body 18 after removal of the installation tool 10.

[0057] FIG. 1 illustrates the reflector holder 19 and driver stake/installation tool 10 in an assembled condition ready for installation. The driver stake 10 may be made from hard tough steel alloy, such as 4140 or 1045 carbon steel. It is contemplated that other materials suitable for insertion into the ground surface may also be used. The driver stake 10 is inserted into the welded reflector holder 19 with the tapered tip 16 protruding through the lower end of the hollow sleeve body 18. The reflector holder 19, which may be made from a stainless steel material, includes the corrosion-resistant hollow sleeve or pipe body 18 and the wide formed, corrosion-resistant washer 17, which is attached to the hollow sleeve body 18 by an attachment weld 24 (shown in FIG. 3). The high-strength driver stake 10 solidly engages metal-to-metal with the welded reflector holder 19 and extends through the reflector holder 19 to pierce the ground surface 21.

[0058] The hollow sleeve body 18 includes retention features 20 in the form of pipe threads defined at or adjacent to each of the upper and lower ends of the hollow sleeve body 18. The pipe threads 20 grip the ground surface 21 to retain the reflector holder 19 within the ground. The pipe threads 20 also make removal of the driver stake 10 from the reflector holder 19 easier by preventing backout of the reflector holder 19 during removal of the driver stake 10. While the retention features 20 shown in FIGS. 1-3 are pipe threads, it is contemplated and will be described below that other retention features may be used.

[0059] A removal pin 26 and/or a removal wire 25 may be provided to facilitate removal of the driver stake 10 from the reflector holder 19. As shown in FIGS. 2 and 3, a hole 11 is defined in the head 33 of the driver stake 10 to receive the removal pin or removal wire 25 therethrough. Before or after the driver stake 10 is inserted into the ground, the removal pin 26 may be inserted through the hole 11. The removal pin 26 provides an easily accessible surface for a user to grab and pull, resulting in removal of the driver stake 10 from the hollow sleeve body 18. The removal wire 25 provides this same benefit, but may form a continuous loop around the hole 11, allowing a user to hook one or more of their fingers around the removal wire 25 in order to apply the necessary force to remove the driver stake 10 from the hollow sleeve body 18. A tool (not shown) may also be used to grasp the removal wire 25 to facilitate removal of the driver stake 10. It is contemplated that both the removal pin 26 and the removal wire 25 may be permanently affixed to the hole 11 and head 33 of the driver stake 10 to always provide an element that helps facilitate removal of the driver stake 10 as just described. Both the removal pin 26 and the removal wire 25 may also be made of a steel, plastic, or otherwise durable material known to those having skill in the art in order to allow the driver stake 10 to be repeatedly used.

[0060] FIG. 2 illustrates an exploded view of the assembly. A radiused corner 12 is defined under the head 33 of the driver stake 10 that prevents the softer hollow sleeve body 18 from binding on the driver stake 10 as the driver stake 10 is driven into the ground surface 21. The radiused corner 12 will contact the hollow sleeve body 18 when the driver stake 10 is driven into the ground. This will force the inner diameter of the hollow sleeve body 18 to roll outward in order to prevent this binding form occurring. The radiused corner 12 may be sized relative to the inner diameter of the hollow sleeve body 18 in order to facilitate the outward rolling of the hollow sleeve body 18 during use. In other words, the radiused corner 12 may be of a size that, during use of the driving stake 10, receives the hollow sleeve body 18 within the radius of the corner in order to roll the hollow sleeve body 18 outward in a direction away from a central axis (not shown) of the driver stake 10 or the reflector holder 19.

[0061] A close-tolerance slip fit outer diameter 13 is defined on the elongated body 76 of the driver stake 10 to keep the reflector holder 19 centered on the driver stake 10 but loose enough for ease of removal. The size of the close-tolerance slip fit outer diameter 13 corresponds to the inner diameter of the hollow sleeve body 18. As the name would suggest, the tolerance formed between the outer diameter 13 and the inner diameter of the hollow sleeve body 18 must be close enough to force the driver stake 10 be centered within the hollow sleeve body 18, but large enough so that any frictional forces potentially acting between the outer diameter and the hollow sleeve body 18 do not impede the removal of the driver stake 10 from the hollow sleeve body 18.

[0062] The elongated body 76 of the driver stake 10 also includes a relief surface 14, which is undersized relative to at least the close-tolerance slip fit outer diameter 13. The relief surface 14 comprises most of the length of the elongated body 76 and provides a clearance between the driver stake 10 and the interior of the hollow sleeve body 18 so as to reduce or prevent frictional forces that may hinder or prevent removal of the driver stake 10 as it is withdrawn from the hollow sleeve body 18 of the reflector holder 19. This can be seen as a gap extending between the elongated body 76 and the hollow sleeve body 18 along the length of the relief surface 14 in FIG. 3. The relief surface 14 may be located lower than the close-tolerance slip fit outer diameter 13 and the radiused corner 12.

[0063] The elongated body 76 of the driver stake 10 includes a tight-fitting outer diameter surface 15 that prevents or limits dirt from entering between the driver stake 10 and the hollow sleeve body 18 and binding or clogging between the elongated body 76 and the hollow sleeve body 18. This may interfere with removal of the driver stake 18 from the reflector holder 19. The tight-fitting outer diameter surface 15 has a diameter that creates a closer tolerance with respect to the inner diameter of the hollow sleeve body 18 than the relief surface 14. The tight-fitting outer diameter surface 15 may have a diameter that is equal or greater than that of the close-tolerance slip fit outer diameter 13. The larger diameter of the tight-fitting outer diameter surface 15 pushes dirt away from the driver stake 10 during insertion into the ground surface 21 and is also shaped to block or prevent dirt from entering the hollow sleeve body 18, which would fill the tolerance formed by the smaller diameter of the relief surface 14 and the inner diameter of the hollow sleeve body 18.

[0064] The driver stake 10 includes the tapered tip 16 at the lower end. The tapered tip 16 is provided with a steep angle to facilitate penetration of the ground surface 21 and to provide a void 27 when removed from the reflector holder 19 to facilitate drainage through the reflector holder 19 and deepen the insertion length of the reflector. The angle of the taper on the tapered tip 16 may vary depending on the type of ground into which the driver stake 10 is being driven. For example, rockier ground may require a sharper taper in order for the driver stake 10 to drive the reflector holder 19 fully into the ground, whereas softer soil may only require a more rounded, or less sharp, taper.

[0065] FIG. 3 illustrates a sectional view of the assembly after being driven into the ground surface 21 with the washer 17 of the reflector holder 19 positioned flush with the ground surface 21 below the level of the grass 22. To install the reflector holder 19 in the ground surface 21, the driver stake 10 is inserted into the hollow sleeve body 18 with the tapered tip 16 extending from the lower end of the hollow sleeve body 18. The head 33 of the driver stake 10 is hammered (not shown) to drive the assembled driver stake 10 and reflector holder 19 into the ground surface 21. The tapered tip 16 defines and creates a hole in the ground surface 21 until the washer 17 is positioned flush with the ground surface 21. The removal pin 26 is then inserted into the hole 11 of the head 33 of the driver stake 10. The washer 17 may be formed to be easily visible under the level of the grass 22 when the reflector rod 23 is removed for grass cutting and landscaping to aid in replacement of the reflector rod 23 when completed.

[0066] FIG. 4 illustrates the same sectional view of the reflector holder 19 installed in the ground surface 21 and the driver stake 10 removed from the reflector holder 19. The reflector holder 19 is embedded into the ground surface 21 below the level of the grass 22. A representative ¼″ diameter driveway reflector rod 23, shown in phantom, is installed in the reflector holder 19 and extends below the lower end of the hollow sleeve body 18 into the driver stake pocket void cavity 27 left by the tapered tip 16 of the driver stake 10 after removal. The pipe threads 20 on the exterior of the hollow sleeve body 18 retain the reflector holder 19 in the ground surface 21.

[0067] FIGS. 5 and 6 illustrate sectional views of a reflector holder 31 having a hollow sleeve body 28 according to another example of the present disclosure. The top of the hollow sleeve body 28 is machined to form a thin-walled extension 29 configured to form a close fit through the inner diameter of the stainless steel washer 17 and to be upset by hammering over the washer 17 to firmly fasten the washer 17 to the hollow sleeve body 28 without welding. After being upset by hammering, the thin-walled extension 29 is deformed to define a flange 30 over the washer 17 to retain the washer 17 on the hollow sleeve body 28. It is contemplated that either hammering the head 33 of the driving stake 10 during the process of inserting the driving stake 10 and reflector holder 19 into the ground may be sufficient to fasten the washer 17 to the hollow sleeve body 28 or a user may be required to hammer the thin-walled extension 29 over the washer 17 before inserting the driving stake 10 into the reflector holder 19 for insertion into the ground surface 21.

[0068] FIG. 7 illustrates a lower portion of a hollow sleeve body 18 of a reflector holder 19 according to another example of the present disclosure. The exterior of the hollow sleeve body 18 includes a retention feature in the form of coarser threads or grooves or a series of barb-shaped threads 32, which may also grip the soil of the ground surface 21 and retain the reflector holder 19 within the ground.

[0069] FIG. 8 illustrates a washer and holder assembly 63 having a molded washer 36 assembled on a stainless-steel holder 34 according to another example of the present disclosure. In this example, the exterior of the hollow sleeve body of the holder 34 includes a retention feature in the form of a spiral groove 50 which may provide a better grip of the soil of the ground surface. While only one spiral groove 50 is shown, additional spiral grooves 50 may be included to increase the gripping characteristics of the assembly 63. It is also contemplated that the retention features 20, 32 previously described may be used.

[0070] FIG. 9 illustrates the molded washer 36 which can be a polypropylene or another UV-resistant plastic compound. The molded washer 36 is injection molded to include a generally dome-shaped body 40 having six flexible fingers 35 (only two identified for clarity). The fingers 35 are defined by six slits 47 (only two identified for clarity). The fingers 35 and the slits 47 extend outwardly along the body 40 from an inner diameter of a center hole 37 of the washer 36. The slits 47 terminate into holes 42 (only two identified for clarity). Both the weld slits 47 and the holes 42 are formed through the molded washer 36 which permits the fingers 35 to flex and have a degree of resiliency during use that they otherwise would not have. The slits 47 and the holes 42 also provide stress relief to the molded washer 36 so that the plastic does not tear, crack, or otherwise deform when the fingers 35 flex or the molded washer 36 undergoes stress during use. As shown, the slits 47 are approximately 0.030 inches wide, and the holes 42 are approximately 0.125 inches in diameter; however, other appropriate sizing may be used depending on the size of the reflector to be held in the washer and holder assembly 63. The washer 36 also includes an outer ring 39 extending about the outer circumference of the washer 36. The outer ring 39 extends in the lower direction more so than any other element of the washer 36, the features of which will be discussed below.

[0071] FIG. 10 illustrates the molded washer 36 as it is being applied to the holder 34. The holder 34 includes a groove 38 that receives the ends or tips of the fingers 35 to affix the washer 36 to the holder 34. The fingers 35 are deflected upwardly before fitting into the groove 38 as the central hole 37 of the molded washer 36 is fit around the top of the holder 34. The top of the holder 34 includes a sharp upper tapered surface 44 to interact with the fingers 35 of the washer 36 and to facilitate the locking of the washer 36 about the holder 34. The groove 38 may be partially defined by an upper corner 46 on a side of the holder generally opposing the upper tapered surface 44 in the upward direction. The groove 38 may also be partially defined by a slanted bottom surface that extends toward the ground.

[0072] The tips of the fingers 35 include rounded lower edges 43 that permit the fingers 35 to roll over the sharp tapered upper surface 44. The contact between the rounded lower edges 43 and the upper surface 44 causes the fingers 35 to flex upwardly during assembly of the washer 36 and the holder 34. As the washer 36 is pushed downwardly and the lower edges 43 of the fingers flex against the upper surface 44 of the holder, the fingers 35 will eventually snap into the groove 38. The fingers 35 also include a squared upper edge 45 that corresponds in shape to the upper corner 46 of the groove 38. These corresponding shapes keep the washer 36 held within the groove 38 during use such as when the assembly 63 is driven into the ground surface 21. The outer ring 39, the dome-shaped body 40, and the fingers 35 provide a strong resistance to flexing or rolling off the holder 34 after assembly. In particular, because the outer ring 39 extends lower than other elements of the washer 36, the outer ring 39 can partially dig into the ground surface 21 and provide some grip to keep the washer 36 within the groove 38 and on the holder 34. The outer ring 39 may include features such as spikes or a serrated bottom surface that help to facilitate its grip into the ground surface 21. The upward pressure load experienced by the washer 36 as it is hammered into the earth 21 is not enough to overcome the resistance of the washer 36 as a result of these features.

[0073] FIG. 11 illustrates a completed washer 36 and holder 34 assembly after the fingers 35 have “snapped” into the groove 38.
