     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new Adjustable Tree Stand embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the Adjustable Tree Stand 10 comprises an elongated, stationary support pole 20 secured to a tree 15 by mounting means 30, and a seat assembly 40 pivotally attached to the support pole 20. 
     As best illustrated in FIGS. 1 through 6, it can be shown that the support pole 20 is generally cylindrical and includes first and second opposite ends. The first end includes a short bearing support shaft 22 the purpose of which will become apparent later. A plurality of spaced holes 24 are formed in the pole between the two ends. The holes form part of an indexing means to be later described. The wholes are spaced at 45 degree intervals around the pole over a predetermined arc, preferably at least 180 degrees. 
     Disposed adjacent each end of the pole 20 are the mounting means 30. Each mounting means 30 includes a mounting bar 31 secured in a suitable fashion, such as by welding, to the support pole 20, and an adjustable length strap 32 having its ends connected to the ends of the mounting bar. The strap length can be adjusted by a ratchet type buckle 33, or by other suitable means. Each strap 32 is placed around the tree 15 and the straps tightened, thus securing the support pole 20 to the tree. 
     In order to level the support pole both vertically and horizontally, a leveling means 34 is provided. Each mounting bar 31 includes first and second arms 35,36 having threaded adjustment holes 37 along each arm. Disposed in one of the holes in each arm is an adjustment screw 38. The ends of the screws engage the tree for adjusting the position of the support pole 20. By suitably adjusting the screws in each arm, the pole 20 can be both vertically and horizontally adjusted relative to the ground to a level position. Although the bottom mounting bar is shown as having the adjustment screws, it should be realized that either of the mounting bars, or both, could have adjusting screws. 
     An alternate embodiment of a leveling means 50 is shown in FIGS. 5 and 6. The support pole 20 is substantially as previously described, and is attached to the tree using mounting means 30 as in FIGS. 1-4. However, disposed between the ends of the pole 20 is a bracket 51. The bracket 51 is secured to the pole in a suitable fashion, such as by welding, and includes a projecting arm 52. The arm 52 includes a plurality of leveling through holes (not shown). A middle pivot member 53 is attached to the bracket 51. The member 53 includes right and left ears 54a,54b on either side of the arm 52 and attached to the arm by a pivot pin 55. Each ear 54a,54b includes leveling through holes 56 corresponding with the holes in the arm 52. A leveling pin 57 is disposed through the holes in the holes 56 in the ears 54a,54b and arm 52. By removing the pin 57 and pivoting the bracket 51 about the pivot shaft 55, the vertical level of the pole 20 can be adjusted. Once the pole is vertically level the pin 57 is inserted into the matching holes to lock the vertical position. Indication means 58 can be formed in the bracket 51 to indicate whether the pole is level or not. The indication means can be a level ball within a slot, or a level bubble within a liquid. Both are well known types of indicators, and the specifics of such devices would be obvious to one having ordinary skill in the art. 
     The middle pivot member 53 includes a pivot disc 59 opposite the ears 54a,54b having a plurality of through holes 60. The disc 59 is pivotally attached to a pivot member 61 by a pivot pin 62 (shown in dashed lines). The pivot member 61 includes a pivot disc 63 which is similar to the disc 59, including a plurality of through holes (not shown) corresponding to the holes 60. A bearing 64 is disposed between the discs 59,63 in order to facilitate pivoting of the discs 59,63 relative to each other. A leveling pin 65 is disposed in the through holes of the discs 59,63 to lock the discs together. By removing the pin 65, the discs can pivot relative to each other to horizontally level the support pole 20. Inserting the pin locks the horizontal position. Indicating means 66 in the form of a level ball in a slot or a level bubble in liquid can be formed in the disc 59 to provide an indication of the horizontal levelness of the pole 20. 
     The end of the pivot member 61 opposite the disc 63 preferably rests against the tree, and could include a strap 67 attached thereto and fitting around the tree for securing the pivot member in place against the tree. 
     The seat assembly 40 is pivotally attached to the pole 20. The assembly includes a pivot plate 41 having one end pivotally attached to the shaft 22 through a bearing 42, such that the plate pivots relative to the shaft 22. The other end of the plate 41 is attached to a seat support pole 43. The pole 43 extends parallel to the pole 20 and is attached at its opposite end to platform 44. The platform 44 has an arcuate inner edge with bearings 45 attached thereto which engage with the outer surface of the pole 20, facilitating pivoting of the seat assembly. 
     The seat assembly includes an indexing means in the form of a spring biased indexing pin 46 extending through the seat support pole 43 and engaging with one of the holes 24. By pulling on the pin 46, it is removed from its hole 24, permitting the assembly to pivot about the pole 20. By releasing the pin, it will be biased back into one of the holes 24 to lock the assembly into one of a plurality of positions over the range of motion. In order to prevent free pivoting and stabilize the pivoting movements, a friction brake means including a friction pad 47 engaging the pole 20 and a threaded adjustment member 48 attached to the pad 47 and extending through the pole 43 are used. The pad 47 frictionally engages the pole 20 to control the rate and ease of movement, and the friction force is adjusted by turning the member 48. 
     The pole 43 also includes a plurality of vertically spaced through holes 49 for pivotally attaching a seat 70 to the pole with a pin 71. The seat can thus pivot relative to the pole 43 to facilitate transportation and storage, and can be vertically adjusted to different heights. 
     In use, the mounting means are attached to the tree, and the pole is leveled. The seat assembly is thus in a safe, level position for a user to sit on. The user sits on the seat and pulls out the pin 46 to permit the seat assembly to pivot relative to the pole 20. The bearings 45 facilitate the pivoting movements and the friction pad 47 smoothes the movements. When the desired position is reached, the user releases the pin 46, which is biased back into one of the holes 24 in the pole 20, thus locking the assembly at that position. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
