Abstract
Abstract The present invention provides a portable tree table that includes two sub-assemblies: a tree belt and bracket assembly, and a table assembly. In use, the tree belt is first tightened about a tree to dispose the bracket at the desired height and adjusted. Then the table assembly is mounted to the bracket. Further adjustments are then made, including extending against the tree and securing stabilizing braces. Disassembly calls for a reversal of these procedures. It is easy to bring in the table and leave the bracket attached to the tree for instances where the table is to be put back up again shortly. Thus there is provided a steady, level work surface easily and securely mounted at a desired height, with no harm to the tree.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
123 words
A portable tree table, comprising: a bracket; belt means having means for connecting the bracket therewith; said belt means being constructed and arranged to be tightly secured together about a tree trunk at any selected height, to thereby securely, removably fasten the bracket to the tree trunk at the selected height; a table member; a bracket fixture secured to the table member so as to be exposed at the rear edge of the table member; said bracket and said bracket fixture having respectively nestable surface features; and securement means for removably securing the bracket fixture to the bracket with said respective nestable surface features in a nested condition, so that the table member is cantilevered out from the tree at the selected height.
Claim 2
Dependent Claim
123 words
A portable tree table, comprising: a bracket; belt means having means for connecting the bracket therewith; said belt means being constructed and arranged to be tightly secured together about a tree trunk at any selected height, to thereby securely, removably fasten the bracket to the tree trunk at the selected height; a table member; a bracket fixture secured to the table member so as to be exposed at the rear edge of the table member; said bracket and said bracket fixture having respectively nestable surface features; and securement means for removably securing the bracket fixture to the bracket with said respective nestable surface features in a nested condition, so that the table member is cantilevered out from the tree at the selected height.
Claim 3
Dependent Claim
21 words
The portable tree table of claim 1, wherein: the nestable surface features are constituted by respective vertically oriented L-shaped channel members.
Claim 4
Dependent Claim
79 words
The portable tree table of claim 1, wherein: said bracket includes means providing a rearwardly opening recess; the means for connecting the bracket with the belt means comprising a U-bolt having a body received in said recess and two threaded legs extending horizontally forwardly through means defining two respective vertically aligned horizontal openings through said bracket, and nut means screwed onto said legs, in front of said bracket, the belt being threaded between the U-bolt body and the bracket.
Claim 5
Dependent Claim
59 words
The portable tree table of claim 3, wherein: said recess is so deep, that if the belt is tightened about the tree trunk while the nut means are loose, and then the nut means are tightened, the belt is caused to encirclingly grip the tree more tightly by being cinched into the recess by the body of the U-bolt.
Claim 6
Dependent Claim
44 words
The portable tree table of claim 3, wherein: said bracket fixture includes means providing a horizontally directed opening therethrough which is sized and placed to fit over one of said legs of said U-bolt, and one of said nut means provides said securement means.
Claim 7
Dependent Claim
43 words
The portable tree table of claim 1, further including: at least one footed leveler screw threadedly mounted to the bracket so as to be projectable horizontally rearwardly therefrom to an adjustable degree, at a level that is vertically displaced from said securement means.
Claim 8
Dependent Claim
44 words
The portable tree table of claim 1, further including: two footed leveler screws, each threadedly mounted to the bracket so as to be projectable horizontally rearwardly therefrom to an adjustable degree, at respective levels that are displaced vertically above and below said securement means.
Claim 9
Dependent Claim
103 words
The portable tree table of claim 1, wherein: the nestable surface features are constituted by respective vertically oriented L-shaped channel members; said channel member of said bracket having a rearwardly presented, vertically oriented trough side defining a rearwardly opening recess; the means for connecting the bracket with the belt means comprising a U-bolt having a body received in said recess and two threaded legs extending horizontally forwardly through means of defining two respective vertically aligned horizontal openings through said bracket, and nut means screwed onto said legs, in front of said bracket, the belt being threaded between the U-bolt body and the bracket.
Claim 10
Dependent Claim
59 words
The portable tree table of claim 8, wherein: said recess is so deep, that if the belt is tightened about the tree trunk while the nut means are loose, and then the nut means are tightened, the belt is caused to encirclingly grip the tree more tightly by being cinched into the recess by the body of the U-bolt.
Claim 11
Dependent Claim
44 words
The portable tree table of claim 9, further including: two footed leveler screws, each threadedly mounted to the bracket so as to be projectable horizontally rearwardly therefrom to an adjustable degree, at respective levels that are displaced vertically above and below said securement means.
Claim 12
Dependent Claim
30 words
The portable tree table of claim 10, wherein: said leveler screws are constructed and arranged to retractingly dispose said feet in said recess when said leveler screws are threaded out.
Claim 13
Dependent Claim
19 words
The portable tree table of claim 11, wherein: said feet are flat-soled and rockably mounted on said leveler screws.
Claim 14
Dependent Claim
55 words
The portable tree table of claim 1, wherein: said bracket fixture comprises an upright channel member disposed in means defining a notch located centrally of the table member in a rear edge of the table member; said channel member having two forwardly diverging, horizontally extending support members secured thereto and underlyingly supporting said table member.
Claim 15
Dependent Claim
33 words
The portable tree table of claim 13, wherein: the bracket fixture is secured to the table member by securement devices which secure the two support members to the underside of the table member.
Claim 16
Dependent Claim
138 words
The portable tree table of claim 1, further comprising: a pair of stabilizer members which are laterally spaced from one another on laterally opposite sides of where said bracket fixture nests with said bracket; each stabilizer member including: a sleeve; a bracket securing the sleeve on the underside of the table member; a stabilizer bar slidingly mounted in the sleeve; and a set screw means on the sleeve which may be tightened to rigidly connect the stabilizer bar to the sleeve and loosened to permit the stabilizer bar to be slid in the sleeve, so that after the table member is mounted to the tree, the stabilizer bars may be slid forwards so that inner ends of the stabilizer bars engage the tree trunk, and the set screw means tightened, thereby preventing side-to-side tipping of the table member.
Claim 17
Dependent Claim
73 words
The portable tree table of claim 15, wherein: the sleeves are tubular and the bars are tubular, but longer than the respective sleeves, so that both ends of each bar protrude from the respective ends of the respective sleeve; the respective protruding tubular ends bar being crimped sufficiently to prevent the respective tubular bars from sliding out of the respective tubular sleeves in either direction even when the respective set screws are loosened.
Claim 18
Dependent Claim
