Cut-tree stand with over-center clamps

机译:带有偏心夹的砍树架子

摘要

A stand for supporting a cut tree for display includes an inner bowl with an outer surface in the form of a segment of a sphere. The inner bowl includes a tree-trunk engaging device for holding the tree trunk in a roughly vertical position in the inner bowl. The inner bowl is supported in a rotatable and tiltable manner within an outer bowl- like support member. The inner bowl can be clamped to the outer bowl- like member by clamps spaced about the periphery of the inner bowl. Each clamp includes a bearing member hinged to the inner bowl, which bears against the exterior of the outer bowl-like member. Each bearing member is forced against the outer bowl-like member by an over-center clamp. The tree trunk is held against a vertical support by a strap-and-buckle arrangement including a cam which simultaneously pinches the strap at two different locations in the clamped position of the cam, for providing continuous adjustment of the strap length.
