A bottommost end 68 of the stake sleeve 62 insertably receives the distal end 16 of the stake 12. The stake sleeve 62 has a pair of pin holes 70 each extending through an outer wall 72 of the stake sleeve 62. Each of the pin holes 70 in the outer wall 72 of the stake sleeve 62 is aligned with the pin hole 18 in the stake 12 when the distal end 16 of the stake 12 is inserted into the bottommost end 68 of the stake sleeve 62.
The lower pipe 20 includes a coupling sleeve 74 and a lower end 76 of the coupling sleeve 74 insertably receives the top end 38 of the bottom section 32 of the lower pipe 20. An inside surface 78 of the coupling sleeve 74 threadably engages the top threads 44 on the outer surface 40 of the bottom section 32. An upper end 80 of the coupling sleeve 74 insertably receives the lower end 46 of the top section 34 of the lower pipe 20 having the inside surface 78 of the coupling sleeve 74 threadably engaging the lower threads 52 on the outside surface 50 of the top section 34. The coupling sleeve 74 has a prominence 82 extending around a full circumference of an exterior surface 84 of the coupling sleeve 74 such that the prominence 82 defines the striking head 24. Additionally, the prominence 82 is aligned with the upper end 80 of the coupling sleeve 74. A pin 86 is extendable through the receiver 22 and the stake 12 when the stake 12 is inserted into the receiver 22 for retaining the stake 12 in the receiver 22. The pin 86 extends through each of the pin holes 70 in the outer wall 72 of the stake sleeve 62 and the pin hole 18 in the stake 12.
An upper pipe 88 is concentrically disposed on the lower pipe 20 such that the upper pipe 88 is slidable upwardly and downwardly along the lower pipe 20. The upper pipe 88 has a hammering head 90 that is distally positioned with respect to a storage cup 92 and the pin 86 is stored in the storage cup 92 when the pin 86 is not in use. The hammering head 90 strikes the striking head 24 on the lower pipe 20 when the upper pipe 88 is urged downwardly on the lower pipe 20 thereby facilitating the stake 12 to be driven into the ground 15. The upper pipe 88 has a bottom end 94 and a top end 96 and the bottom end 94 of the upper pipe 88 slidably receives the upper end 48 of the top section 34 of the lower pipe 20. An outside surface 98 of the upper pipe 88 has bottom threads 100 located adjacent to the bottom end 94 of the upper pipe 88 and the outside surface 98 of the upper pipe 88 has top threads 102 located adjacent to the top end 96 of the upper pipe 88.

In use, the stake 12 is inserted into the stake sleeve 62 and the pin 86 is extended through the stake sleeve 62 and the stake 12 for retaining the stake 12 in the stake sleeve 62. The tapered end 14 of the stake 12 is positioned at a desired location on the ground 15 and the upper pipe 88 is repeatedly driven downwardly on the lower pipe 20 to facilitate the prominence 112 on the striking sleeve 104 to strike the prominence 82 on the coupling sleeve 74. In this way the striking force of the striking sleeve 104 is transferred into the stake 12 to facilitate the stake 12 to be driven into the ground 15. The pin 86 is removed from the stake sleeve 62 and the stake 12 and the pin 86 is placed in the storage cup 92 for storage once the stake 12 has been driven into the ground 15.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
