The terminology used in the description presented herein is not intended to be interpreted in any restrictive or limited way, simply because it is being utilized in conjunction with the detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the invention described herein.

(16) FIGS. 1 and 2 are top and bottom perspective views, respectively, of a tree stand 10 according to a preferred embodiment of the present invention. FIG. 3 is an elevation view of the tree stand 10 of FIGS. 1 and 2.

(17) The present invention relates to tree stands 10 which are compact for shipping and easily assembled. A preferred embodiment of the tree stand 10 comprises a base assembly 20 and a plurality of legs 60 which are removably attachable to the base assembly 20. Preferably, the base assembly 20 includes a bottom 22 joined to a sidewall 24, and a plurality of upright stanchions 26 joined to the bottom 22 and to the sidewall 24 as shown in FIG. 1. The bottom 22, sidewall 24 and upright stanchions 26 define a water reservoir 28.

(18) Preferably, the plurality of upright stanchions 26 are connected, joined or integrally formed with the sidewall 24 and the bottom 22. Preferably, three or four upright stanchions 26 are desirable to secure a tree trunk to the tree stand 10. The stanchions 26 preferably have a height greater than the height of the sidewall 24.

(19) Each upright stanchion 26 includes a bore 30 for receiving a bolt 32 (FIG. 4) used to secure a tree in an upright position. In a preferred embodiment, the bore 30 is a threaded Tore and threadedly engages the bolt 32 in an upper portion of the upright stanchion 26.

(20) As shown in FIGS. 1-3, the embodiment of the tree stand 10 has three stanchions 26 and three legs 60 equally spaced around the circumference of the base assembly 20. It is to be understood that the invention is not limited to three stanchions 26 and three legs 60. Preferably, the number of stanchions 26 and number of legs 60 is the same. Preferably, each stanchion 26 is radially aligned with and adjacent to a joined leg 60 as shown in FIG. 1.

(21) Referring to FIGS. 2 and 5, the upper portion of the sidewall 4 preferably forms a double-wall upper lip 34 reinforced with gussets to provide added strength and rigidity to the base assembly 20. The upright stanchions 26 are also preferably connected to the double-wall upper lip 34.

(22) Referring to FIG. 1, a restraining device 36, preferably comprising one or more upright nails with pointed end extending upward, is located near the center of the bottom 22 in the water reservoir 28. The pointed end of the nails 36 extend upwardly a short length and are provided to engage the bottom of a tree trunk. The restraining device 36 helps to lock and centralize the tree before final adjustment and prevents the bottom of the tree trunk from lateral movement when the tree is mounted in the tree stand 10. Preferably, the nails 36 are in the mold during the molding process of the base assembly 20.

(23) As shown in FIGS. 4 and 5, the legs 60 are elongate and include a connecting end 62 and a distal end 64. The base assembly 20 includes a plurality of receivers 38 for attaching the connecting end 62 of the legs 60 to the base assembly 20 as shown in FIGS. 5 and 6. The receivers 38 are preferably formed within a lower portion of the upright stanchions 26 and provide further strength and rigidity to the stanchions 26 and base assembly 20. Preferably, the leg connecting end 62 and the receiver 38 securely connect to one another. In the illustrated preferred embodiment, the secure connection is accomplished with a sliding friction fit somewhat similar to a dovetail-type connection. It is to be understood that other types of connections may be used to securely connect the legs 60 to the base assembly 20.

(24) Referring to FIGS. 5 and 6, the receiver 38 has an opening in the bottom and lower end of the sidewall 24 arranged and designed to receive the connecting end 62 of the leg 60. The leg 60 preferably attaches to the base assembly 20 at the lower end of the base assembly 20. As shown in FIGS. 1 and 3, the attached leg 60 has a low vertical profile and is below the height of the sidewall 24, and preferably is below the height of the double-wall upper lip 34.

(25) Referring to FIGS. 5 and 6, the leg connecting end 62 is preferably an elongated dovetail extension extending from the leg 60 arranged and designed to be slidably received within a corresponding receptacle of the receiver 38, Preferably, the leg connecting end 62 slides into the receiver 38 from the below the bottom 22 of the base assembly 20. The connecting end 62 and receiver 38 may include a catch or friction fit upon engagement to further secure the leg 62 to the base assembly 20. The engagement of the connecting end 62 with the receiver 38 maintains the leg connecting end 62 within the base assembly 20 and prevents the legs 60 from releasing radially outward of the base assembly 20.

(26) Preferably, the distal end 64 of each leg 60 includes a lower foot 66. With the legs 60 attached to the base assembly 20, the tree stand 10 may be supported on a floor by the feet 66 when there is no downward load (e.g., a tree) on the tree stand 10. In other words, the only portion of the tree stand 10 contacting the floor may be the feet 66. However, with a tree mounted in the tree stand 10, the bottom 22 of the base assembly 20 will contact the floor and the feet 66 will also be in contact with the floor. The feet 66 are provided to ensure that all three legs 60 remain in contact with the floor even if the floor is not perfectly flat. This eliminates any wobbling of the tree stand 10 and provides support against the tree toppling over while in the stand 10.

(27) As stated above, each of the stanchions 26 has an internal threaded opening 30 for receiving a bolt 32 which is arranged and designed to be rotated to bring a contact point 32a of the bolt 32 into contact with the trunk of the tree, Preferably, the upper portion of each stanchion 26 is located above the upper surface of the water reservoir 28 to facilitate the engagement of the bolts 32 with the tree trunk. By molding the stanchions 26 inwardly from the sidewall 24 of the stand 10, the support point for each of the bolts 32 on each of the stanchions 26 is close to the tree which shortens the length of each bolt 32 from each stanchion 26 to the tree to thereby minimize a desirable forces on the bolts 32 or the stanchions 26 when the bolts 32 are tightened into contact with the tree. Therefore, even though the stand 10 is made of a plastic resin, the bolt tightening forces do not crack or break the bolts 32 or the stand 10.

(28) Preferably, each of the bolts 32 is formed with acme threads or other fast threads that can be rotated to travel rapidly in inward and outward axial directions for alternately securing and releasing the contact of the bolt end point 32a with the tree trunk. Each bolt 32 has a handle 32b to facilitate its rotation. Each bolt 32 is formed of a plastic resin such as polypropylene in the preferred form of the invention.

(29) Preferably, the bolts 26 are molded separately from the legs 60. However, preferably the legs 60 include an open bottom portion having a releasable engagement mechanism, for example a clip or prong, to connect a bolt 26 to the leg 60 for purposes of shipping. The bolts 26 are removable from the engagement mechanism, preferably without a tool. The bolts 26 may be frictionally connected to the legs 60.

(30) Preferably, the tree stand 10, including the base assembly 20 and the plurality of legs 60, are molded of a plastic resin such as polypropylene, and the bolts 26 are preferably molded separately from the rest of the stand 10. The bolts 26 are then packaged with the rest of the tree stand 10 for shipping. For smaller trees that are usually displayed on a table top, the bolts 26 may be made entirely of a plastic resin such as polypropylene, but for larger sizes of stands 10, a steel reinforcing member may form the core of each molded bolt.

(31) An example of a tree stand 10 according to a preferred embodiment of the present invention includes a base assembly 20 having an outer diameter of approximately 11.5″ and each leg 60 having an overall length in the range of 12″ to 14.5″.
