A ground lock is formed of a main shaft having a first latching structure near its upper end and a ground fastener at its lower end. A mating member provides a cooperative latching structure and slides on the main shaft between raised and lowered positions. In one of the raised or lowered positions, the two latching structures are latchable, allowing the mating member to drive the main shaft to engage or disengage the ground fastener. In the other of the raised or lowered positions, the second latching structure is non-latchable with the first latching structure such that the main shaft is disabled from driving the ground fastener.

1. A ground lock providing an attachment for securing an external object, comprising: a vertically elongated main shaft having upper and lower ends, having a ground fastener fixed to said lower end thereof, configured to alternatively engage or disengage the ground when suitably driven, the main shaft having a first latching structure, and wherein said main shaft includes an upper portion of a predetermined, relatively smaller transverse dimension with a head juxtaposed at the top thereof having a predetermined, relatively larger transverse dimension;a driver including a second latching structure, engaging the main shaft for longitudinal movement thereon between first and second relative longitudinal positions, wherein in said first longitudinal position said first and second latching structures are latchably positioned for said driver to drivingly engage said main shaft and suitably drive said ground fastener through the first and second latching structures to alternatively engage or disengage the ground, and wherein in said second longitudinal position the first and second latching structures are mutually non-latchably positioned, disabling the driver from drivingly engaging the main shaft from suitably driving the ground fastener through the first and second latching structures;said driver includes a driver sleeve that is slidably engaged on a portion of the main shaft;said driver sleeve includes a lower portion of predetermined, relatively smaller transverse dimension sized to pass said upper portion of the main shaft but not said head, and a juxtaposed upper portion of predetermined, relatively larger transverse dimension sized to pass said head:wherein said second latching structure is spaced above said lower portion of the driver sleeve sufficiently that in said second longitudinal position said head is receivable between the second latching structure and the lower portion of the driver sleeve, containing the head of the main shaft within the driver sleeve. 2. The ground lock of claim 1, further comprising: a lock engagable in said second latching structure when said driver sleeve is in said second longitudinal position, maintaining said head between the second latching structure and the lower portion of the driver sleeve, thereby protecting the head against unauthorized access. 3. The ground lock of claim 1, further comprising: an attachment member that includes said driver sleeve;wherein:said first latching structure is a first transverse bore; andsaid second latching structure is a portion of said driver sleeve suited to cooperate with said first transverse bore in locking together the driver sleeve and main shaft such that the attachment member can suitably drive said ground fastener. 4. The ground lock of claim 3, wherein: said second latching structure is a second transverse bore through said driver sleeve, positioned to be alignable with said first transverse bore such that the aligned bores can, in use, be pinned in common to lock together the driver sleeve and main shaft. 5. The ground lock of claim 4, further comprising: a pin sized for pinning together said aligned first and second transverse bores. 6. A ground lock, comprising: a ground lock-driving shaft having opposite proximal and distal ends;a ground fastener carried on said ground lock-driving shaft near the distal end thereof;a driver sleeve having opposite proximal and distal ends aligned with those of the ground lock-driving shaft, telescopically engaged over said ground lock-driving shaft and longitudinally slidable thereon between a first position on the ground lock-driving shaft and a second position longitudinally offset toward the proximal end of the ground lock-driving shaft from said first position;wherein said ground lock-driving shaft defines a first transverse bore near the proximal end thereof, suited, in use, to receive a pin therethrough;wherein said driver sleeve defines a catch suited, in use, to latch with a transverse pin and is alignable with said first transverse bore when in said first position of the driver sleeve on the ground lock-driving shaft such that a transverse pin latched with said catch is receivable through the first transverse bore;wherein when the driver sleeve is in said second position, the catch is exposed above the proximal end of the ground lock-driving shaft;whereby in the first position, in use, a transverse pin placed through the first bore of the ground lock-driving shaft is latchable with said catch of the driver sleeve to form a rotationally latched engagement between the ground lock-driving shaft and driver sleeve, such that rotation of the driver sleeve rotates the ground lock-driving shaft to engage or disengage the ground fastener from the ground, and in the second position, in use, a pin placed through the catch of the driver sleeve will lock out the driver sleeve from rotationally latched engagement with the ground lock-driving shaft. 7. The ground lock of claim 6, further comprising: a keeper carried on said ground lock-driving shaft near the proximal end thereof, sized to retain said driver sleeve against removal from the proximal end of the lock-driving shaft. 8. The ground lock of claim 7, wherein said driver sleeve further comprises: a handle extending laterally of the driver sleeve for twisting the driver sleeve. 9. The ground lock of claim 8, wherein said handle has a closed loop configuration for providing an attachment to secure external objects. 10. The ground lock of claim 6, wherein said catch is a second transverse bore through said driver sleeve. 11. The ground lock of claim 6, wherein said catch is a forked distal end of said driver sleeve. 12. The ground lock of claim 6, wherein said catch is an ear extending distally from the distal end of said driver sleeve. 13. A ground lock for securing an object to the earth, comprising: a longitudinal shaft having a top end, an upper portion, and a lower portion, configured with a first transverse bore extending through said shaft in the upper portion thereof;ground-fastening means carried on said lower portion of said shaft and adapted to penetrate into or be removed from the ground for alternatively engaging with or disengaging from the ground;a locking pin;a driver carried on said upper portion of the shaft, including a longitudinally slidable sleeve engaged over the shaft, defining a second transverse bore;wherein when the slidable sleeve is positioned at a first height on the shaft, the second transverse bore is alignable with said first transverse bore such that said locking pin can be inserted through the aligned bores to lock the driver and shaft for rotation in unison, whereby the driver can rotate the shaft to alternatively engage or disengage the ground-fastening means with the ground; andwherein when the slidable sleeve is positioned at a second height on the shaft, the second transverse bore is above the top end of the shaft and the locking pin can be inserted through the second bore to lock out the slidable sleeve against movement to the first height, preventing the driver and shaft from being locked through the aligned bores for rotation in unison, whereby the driver cannot rotate the shaft to disengage the ground-fastening means from the ground; andwherein said driver further comprises a handle portion configured as a closed loop suitable for securing an object to the earth. 14. The ground lock of claim 13, wherein: said ground-fastening means comprises an auger and said handle portion is suitably configured for hand engagement to rotate said auger when the driver and shaft are locked for rotation in unison. 15. The ground lock of claim 13, wherein: said slidable sleeve has an upper portion of a relatively larger transverse dimension and a lower portion of relatively smaller transverse dimension; andfurther comprising a keeper at said top end of said shaft, sized to fit within said upper portion of the slidable sleeve and to retain the lower portion of the slidable sleeve below the keeper. 16. The ground lock of claim 15, wherein: said second transverse bore is formed in said upper portion of said slidable sleeve. 17. The ground lock of claim 15, wherein said slidable sleeve further comprises: an upper sleeve forming said portion of the slidable sleeve having a larger transverse dimension;a lower sleeve forming said portion of the slidable sleeve having a smaller transverse dimension; anda junction where telescoped lengths of said upper and lower sleeves overlap and a top end of the lower sleeve defines a centrally extending shoulder within the upper sleeve, sized to retain said keeper. 18.
