  1. 1
    What is claimed is:1. A stand for supporting a trunk of a tree, comprising a fluid-tight container including a lower member to be rested upon a surface and an upper member providing an intermediate portion in spaced relation to said lower member and having an opening therethrough, an annular eleother to provide a rigid, fluid-tight joint. Stated other- βθ ment constituted as a part of said intermediate portion of - - - - ------ .-------—.-j the upper member having an upwardly facing convex surface and a downwardly facing concave surface in vertical alignment and a first continuous cylindrical flange on the intermediate portion of the upper member in bounding facing, annular shoulder or surface. The downwardly and upwardly facing annular shoulders 27 and 29 are in a plane passed perpendicularly through the cylindrical sleeve 25. The lower end portion of said cylindrical sleeve is cut away to provide an oblique annular surface 30 extending upwardly and outwardly from the lower end of the cylindrical sleeve to the periphery of a lower part of the second annular rib 28. The cylindrical sleeve 25 will be composed of material having sufficient rigidity to be capable of being forcibly assembled with the container and strut unit of the stand or holder and to retain a tree assembled therewith in upright position. And said cylindrical sleeve will be of such nature that an upper portion thereof can be constricted. The upper and lower base members 10 and 11 of the container and the strut unit 20 of the stand or holder will be assembled, as disclosed in Fig. 3 of the drawing, before the cylindrical sleeve 25 is incorporated in the structure. In said Fig. 3 said cylindrical sleeve is disclosed as when about to be inserted by force into the cylindrical flange 16 of said upper base member. Forcible insertion is to be made while the cylindrical sleeve, is unheated. The oblique annular surface 30 of said cylindrical sleeve is of diameter at the outer, upper circumference thereof somewhat greater than is the diameter of the internal surface of the annular lip 33 of the cylindrical flange 16 when unstretched, as it is disclosed in Fig. 3. Said cylindrical flange 16 and the cylindrical flange 24 of the strut unit will be radially stretched in response to forcible entry of the cylindrical sleeve into the container and the external surface of the cylindrical flange 16 will be pressingly engaged against the internal surface of said cylindrical flange 24. The downwardly and upwardly facing annular shoulders or surfaces 27 and 29 provided by the first and second annular ribs 26 and 28, respectively, upon the cylindrical sleeve are spaced apart a distance less than are the external convex surface of the annular element 19 and the lower ends of the cylindrical flanges 16 and 24. The construction and arrangement will be such that when the upwardly facing shoulder or surface 29 shall have been forced downwardly to position where in transverse alinement with said lower end of said cylindrical flange 16, the downwardly facing annular shoulder or surface 27 will have engaged the external convex surface of said annular element and caused the internal concave surface thereof to become pressingly engaged against the external convex surface of the annular member of the strut unit. When said upwardly facing shoulder or surface becomes transversely alined with the lower end of the cylindrical flange 16, said radially stretched cylindrical flanges 16 and 24 will be permitted to become partially unstretched thus to seat the upwardly facing shoulder or surface 29 of the second annular rib 28 in pressingly engaged relation with the lower ends of the cylindrical flanges 16 and 24. The portions of the upper base member and the strut unit which are between the first and second annular ribs when said cylindrical sleeve and said strut unit are assembled will be in snug, pressing engagement with each wise, the cylindrical sleeve will be rigidly supported in vertical position upon and secured in fluid-proof manner to the container of the stand or holder. The strut unit 20 functions to maintain the upper and ______---------lower base members of the container of the stand or 05 relation to said opening and extending downwardly from holder in spaced relation and the cylindrical flange 16 in ' ’ · < .· 1 1 * - ·—· upright position while the cylindrical sleeve 25 is being -------__ _____ — . _ forcibly inserted into its assembled position. The cylin- ing an upwardly facing convex surface fitted to the downdrical flange 24 of the strut unit and said cylindrical wardly facing concave surface of said annular element sleeve when inserted grasp said cylindrical flange 16 there- 70 and a second continuous cylindrical flange in proximate between under resilient pressure. The internal concave surface of the annular element 19 and the external convex surface of the annular member 23 are maintained in pressingly engaged relation. Tree stands of the present . . general character are subjected to rough handling, espe- 75 tinuous cylindrical flange and retaining an external sur40 an interior margin of the annular element, a strut unit within said container providing an annular member havsurrounding relation to said first continuous cylindrical flange, a resilient hollow cylindrical sleeve having a lower end portion thereof situated in said opening in pressingly engaged relation with an internal surface of the first con2,928,633 5 6 reof m pressmgly engaged relation with an internal surface of said second continuous cylindrical flange, a downwardly facing surface integral with a portion of an external surface of the hollow cylindrical sleeve above the annular element and an upwardly facing surface 5 integral with an external surface of said hollow cylindrical sleeve at a location below and in spaced relation to said downwardly facing surface, said downwardly facing surface being in proximate relation to the upwardly facing convex surface of said annular element, said upwardly facing surface being in proximate relation to the lower end of at least one of said continuous cylindrical flanges and the downwardly and upwardly facing surfaces in cooperation with each other maintaining the downwardly facing concave surface of the annular element and the 15 upwardly facing convex surface of the annular member in pressingly engaged relation.

  2. 2
    The combination as specified in claim 1 wherein a lower end portion of said first continuous cylindrical flange is constituted as an interiorly offset lip in grippingly engaged relation with an external surface of said hollow cylindrical sleeve.
