Abstract
Abstract The notch in the back of the tree stand fits over a tree trunk and the flexible steel band encircles the trunk and supports the platform. Each side of the platform is provided with a pair of legs each of which is connected to the platform by pivots arranged at 90° to each other to let the legs be raised or lowered and to let the legs move inwardly. Each front leg carries a guide for the flexible steel band and also carries a locking device actuated by a knob. The device has a lock pin engageable with the band in any position of the legs and also has a pin engageable with the rear leg only in the raised (operative) position of the legs. The rear leg includes a flexible steel portion which can twist to accommodate misalignment at the connection between the legs.

Claim 1
Independent Claim
86 words
A tree stand having a platform provided with a notch therein adapted to receive a tree trunk, a flexible metal band adapted to embrace the tree trunk, support means on each side of the platform for adjustably engaging the band and fixing the band at an angle relative to the platform whereby the band engages the tree in back of and above the platform, said support means being connected to the platform by pivot means allowing the support means to move sideways relative to the platform.
Claim 2
Dependent Claim
86 words
A tree stand having a platform provided with a notch therein adapted to receive a tree trunk, a flexible metal band adapted to embrace the tree trunk, support means on each side of the platform for adjustably engaging the band and fixing the band at an angle relative to the platform whereby the band engages the tree in back of and above the platform, said support means being connected to the platform by pivot means allowing the support means to move sideways relative to the platform.
Claim 3
Dependent Claim
66 words
A tree stand according to claims 1 in which each of said support means includes a pair of legs each of which is pivotally connected to the platform for movement between raised and lowered positions in addition to said sideways movement, said legs being slidably interconnected for movement between said raised position and said lowered position, and means for fixing said legs in said raised position.
