发明名称 Tree stands
摘要 A tree stand is described including a fluid reservoir of a tree retaining member including tree gripping means. The gripping means comprises projections arranged on an interior surface of the tree retaining member and extending in a radial fashion, inwardly from the interior surface of the tree retaining member. The projections run substantially axially within the tree retaining member and include a sharp or pointed portion to at least partially penetrate the trunk of a tree inserted into the tree retaining member. The tree retaining member is configured to hold a tree inserted therein by resisting lifting of a tree inserted therein relative to the tree stand, without using moveable mechanical means comprising screws or bolts. The tree retaining member is connected to a base. The tree stand also includes strengthening means configured between the fluid reservoir and the tree retaining member. The strengthening means comprises hollow ribs.
