Abstract

A "Push n' Lock" tree stand is disclosed. The tree stand has a compact construction with an improved center of gravity and elongated folding legs. The legs of the tree stand are each broadened in width at their fold-up pivot point and then tapered to a narrower width at their distal ends. This taper provides an improved center of gravity about the base, thus reducing the tendency of the tree to tip over. The legs are sufficiently elongated to provide good balance in their extended position. The tree stand provides a hollow, cylindrical base for supporting severed tree trunk. The bottom of the cylindrical base comprises three or four integrally spaced flange members that arc disposed in a triangular or cross pattern about the base to pivotally receive the folding legs.

Description

"Push n' Lock" Tree Stand FIELD OF THE INVENTION

The present invention relates to the construction of a tree stand with an improved center of gravity and elongated folding legs. The tree stand provides a push and lock mechanism to ease of operation.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is featured a fold-up tree stand. The fold-up design of the tree stand provides a solid, compact construction having an improved center of gravity and a vertical collapsing profile for ease of storage. The tree stand comprises a hollow, cylindrical base for supporting a trunk of a severed tree. The bottom of the cylindrical base comprises three or four integrally spaced flange members that arc disposed in a triangular or cross pattern about the base.

The legs are each pivotally pinned to a respective flange member. Each of the legs comprises a locking tab disposed opposite its pivot. The stand is pivotally operative between a first, fold-up vertical posit ion and a second, horizontally extended, operative position. In the first, fold-up position (used for storage purposes), each locking tab is projected outwardly a short distance from the base in a radial manner. In the extended, operative position, each of the locking tabs fits flush with the outer surface of the hollow, cylindrical base.

A cylindrical collar is disposed about the cylindrical base. The cylindrical collar is free to move along a vertical axis of the base in order to ride over and capture the locking tabs when the legs are in the second, horizontally extended position. In the captured state, the locking tabs prevent the legs from pivoting back to their first, fold-up position. The cylindrical collar contains apertures and adjacent lands that are disposed about an inner, annular surface disposed adjacent the outer surface of the cylindrical base. The cylindrical collar is free to rotate about the cylindrical base between a first, unlocked tab position and a second, locked tab position.

The legs are pivoted to their extended, operative position to form a stable cross or triangular patterned pedestal when a tree is to be inserted into the hollow portion of the cylindrical base.
In this position, the collar is vertically placed over the locking tabs and the tabs enter the inner apertures in the collar. The collar is then turned approximately a sixteenth of a full turn to bring the lands in contact with the tabs, thus capturing the tabs in the second, locked tab position. The legs of the tree stand are each broadened in width at their fold-up pivot point and then tapered to a narrower width at their distal ends. This taper provides an improved center of gravity about the shaft of the tree trunk, thus reducing the tendency for the tree to tip over. The legs are sufficiently elongated to provide good balance in their extended, operative position. It is an object of the present invention to provide an improved, collapsible tree stand. It is another object of this invention to provide a collapsible tree stand that is rugged and that also easily folds up for storage. It is yet another object of the invention to provide a collapsible tree stand that has an improved center of gravity in order to prevent the tree from tipping over.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Generally speaking, the invention features a "push n' lock" tree stand. The fold-up design of the tree stand provides a solid, compact construction having an improved center of gravity and a vertical collapsing profile for ease of storage.

The legs of the tree stand are each broadened in width at their fold-up pivot point and then tapered to a narrower width at their distal ends. This taper provides an improved center of gravity about the shaft of the tree trunk, thus reducing the tendency of the tree to tip over. The legs are sufficiently elongated to provide good balance in t heir extended position.

Now referring to FIG. 1, a first embodiment of a three-legged tree stand in accordance with the teachings of this invention is illustrated in its leg-extended, operative position. The invention features both the three-legged tree stand and a second embodiment featuring a four-legged tree stand 1 a, as depicted in FIG. 2. For all intended purposes, the respective tree stands 1 and la are constructed and function in a similar fashion. Therefore, only the first, three-legged embodiment need be described in detail. The legs 10 of each first and second tree stand embodiment are pivotally attached to a hollow cylindrical base 12, as will be explained herein after with reference to FIGS. 3 and 4. A collar 18 disposed about the cylindrical base 12 locks the legs 10 in their extended, operative position, as will be explained hereinafter with respect to FIG. 7.

Referring to FIG, 5, the hollow, cylindrical base 12 supports a severed trunk of a tree (not shown). The thickened top port ion 15 of the cylindrical base 12 , in order to capture an inserted, severed, tree trunk, which is inserted into the hollow portion 11.

Referring to FIGS. 3, 4, and 6, a bottom portion 16 of the cylindrical base 12 comprises three or four integrally spaced flange members 14. The flange members 14 are disposed in a triangular or cross pattern about the bottom of the base 12 (i.e., at one hundred twenty or ninety degrees around the bottom). The legs 10 are each pivotally pinned to a respective flange member 14 by pivot pins 19. Each of the legs 10 comprises a locking tab 18 (FIG. 3) dispose d opposite its pivot pin 19. The stand 1 is pivotally operative between the first, fold-up vertical position (FIG. 3) and the second, horizontally extended, operative position, as shown in FIGS. 1 and 2. In the first, fold-up position (used for storage purposes), each locking tab 18 is projected outwardly a short distance from the base 12 in a radial manner. In the extended, operative position, each of the locking t abs 18 fits flush with the outer cylindrical surface 24 (FIG. 7) of the hollow, cylindrical base 12. The cylindrical collar 9 is free to move in translation along the longitudinal length of the base 12 in order to ride over and capture the locking tabs 18, when the legs are in the second, horizontally extended position, shown in FIGS. 1 and 2. In the captured state, the locking tabs 18 prevent the legs 10 from pivoting back to their first, fold-up position.

The cylindrical collar 9 contains apertures 23 that are disposed about an inner, annular surface adjacent the outer surface 24 of the cylindrical base 12. The cylindrical collar IN is free to push (PUSH TO LOCK) about the cylindrical base 12 at lock tab position (FIG. 7).
Referring to FIG. 6, the legs 10 are pivoted (arrow 17) to their extended, operative position to form a stable cross or triangular patterned pedestal, after which a tree is inserted into the hollow portion 11 of the cylindrical base 12. In this position, the collar 9 is vertically placed over the locking tabs 18, and the tabs 18 enter the inner apertures 15 in the collar 9. The collar 9 is then push and to bring the lands 15 in contact with the tabs 18, thus capturing the tabs 18 in the locked tab position.
Referring again to FIG. 3, the legs 10 of the tree stand are each broadened in width at the point of their pivot pin 19, and then tapered to a narrower width at their distal end 20, which provides a larger profile about the base. This taper provides an improved center of gravity about the base and the shaft of the tree trunk, thus reducing the tendency for the tree to tip over. The legs are sufficiently elongated to provide good balance in their extended, operative position.
