发明名称 Tree stand with adjustable jack plate for leveling
摘要 A tree stand for use in hunting or the like has a vertical member with two platforms attached to it to provide a seat and a foot rest. A jack plate is pivotally attached to the back of the vertical member. The jack plate is securely fastened to a tree trunk or limb. The angle between the vertical member and the jack plate is adjusted with an adjustment strap connecting the two. By adjustment of that angle, the vertical member can be maintained in a vertical position regardless of the angle of the trunk or limb to which the jack plate is fastened.
