Abstract: A self-adjusting apparatus is provided for clamping and supporting a substantially cylindrical element. When an element is placed in the self-adjusting apparatus, the element is supported at about 90° from the surface on which the apparatus sits. This is achieved with an integrated clamping mechanism and, preferably, with a self-centering mechanism comprising flexure springs and a retaining-center pin. The clamping mechanism applies a substantially radial force on the element that is directly proportional to the substantially cylindrical element's weight, and can be less than the weight of the element, preventing damage to the element. The present invention can include a liquid management system for when the apparatus supports a tree trunk. The liquid management system can include a reservoir, a funnel for filling the reservoir, a capillary wick and mat that provides water to the tree even when it is above the level of water in the reservoir.

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: A portable, collapsible stand for supporting a cut tree or other generally cylindrical object in a vertical orientation, comprising a plurality of formed leg pair members (14) connected at their centers and radially arrayed to form a central, vertically oriented chamber (32) into which the object is placed. The weight of the object forces the chamber downwards causing the upper extremes (18,24) of the chamber to grasp the object by a spring force. This chamber is then clamped circumferentially to the object for stability. Means for adjusting the apparent vertical orientation of the supported object operate by changing the angle of the leg sections (12,28) and simultaneously tilting the vertically oriented chamber (32) in the required direction.

Abstract: A lockable leveling structure has a vertical stand with a base at one end. The stand has legs pivotally attached and can be locked in a stable manner by a slide collar and thumb screw. The slide collar is movable about the vertical stand and makes a solid contact against the end of the legs causing the outer end of the legs to move up or down respective to one another to compensate for an unlevel support surface. This provides a solid motionless structure that can carry a load bearing fixture in desired degree of levelness in a safe, stable, novel manner without the use of shims, or altering the surface while on unlevel surfaces. The slide collar is unlocked and raised up the stand member allowing the bottom of the legs to rotate up toward the vertical stand member causing the structure to be in a compact package for storage or transport.

Abstract: A tree holder, suitable for holding the trunk of a cut-off tree in an upright attitude includes a cup into which the lower end of the trunk is placed, the cup having a lip from which a skirt extends downwardly and outwardly. The skirt has the shape of a frustrum of a cone. Three legs are slidably attached to the skirt on its inside, and each leg can be slid toward and away from the vertex of the cone independently. Each leg is slid upwardly with respect to the skirt until the upper end of the leg is in firm contact with the trunk of the tree. At that point, the skirt and the leg are drawn together by tightening a threaded fastener, thereby clamping the leg to the skirt. The tree holder is notable for its simplicity of design and for its ability to accommodate asymmetric and crooked tree trunks.

Abstract: A holder for Christmas trees which includes a container supported above ground level, legs to support the weight of the tree attached to the container, and holding members extending from the legs.
