摘要:
The tree stand includes a column permanently or semi-permanently secured to a tree or other support by one or more circumferential cables or bands and/or one or more threaded fasteners driven into the tree. The ends of the band are captured in a slot on the column, the threaded fastener, or optionally an unthreaded pin, capturing the ends of the band in the slot. Access to the pin is blocked by a lock that may only be removed by a person having the proper key, thus assuring that the column can be safely left in place. A platform and seat are removably attached to the column when use of the stand is desired. The user of the stand may install several columns in various locations and transport only a single platform and seat to one of the previously installed columns when the stand is to be used.
