Abstract: A self-clamping Christmas tree stand provides a stable platform for a Christmas tree that allows simple installation and adjustment of the tree angle without having to be positioned under the tree to perform the adjustments. The tree stand uses the weight of the tree to firmly clamp the tree's trunk. A clamping mechanism provides a constant grip that will not loosen unless an upward force is provided by the user. The adjustment range of the tree trunk angle with respect to the vertical plane may be varied to accommodate tree trunks of different shapes. Lastly, the tree stand includes a large liquid reservoir to maintain the tree's moisture content.
Abstract: This invention provides a method for using one or more inflatable three-dimensional humanoid figures for use in background scenes associated with still photography, motion pictures and video productions which are low in cost, lightweight, easy to use, easy to store, easy to transport and provides a greater range of viewing angles. It is also envisioned that this invention can be used for corporate conventions requiring the illusion of a large number of participants, in advertising and other functions where the illusion of large numbers of people enhance the overall objective of the functions.
