An improved teeter totter apparatus that can be adjusted for different weight individuals who together can use the apparatus. The individuals will be able to manually make adjustments to the beam by offsetting it upon its tripod support structure. Users will then be able to apply vertical force in order create an up and down rocking motion. At the same time they will be able to exert a horizontal force to move the apparatus in a horizontal rotational plane around the upstanding support structure. This will induce a vertical and horizontal motion that will exhilarate and thrill the participants.

SUMMARY OF THE INVENTION
A rotatable teeter totter apparatus that is manually propelled. It includes a stationary tripod base having a plurality of linear feet and a vertical stanchion fixedly coupled to the feet and extending upwardly therefrom. A rocker arm pivoting assembly sits over the top of the vertical stanchion. The rocker arm has an outboard end with a seat at opposite ends. The middle portion of the rocker arm is also designed with a plurity of mounting slots in order to balance the loading of different weights on opposite ends of the teeter totter rocker arm, thus the teeter totter can be offset to accommodate users of different height and weight, particularly when vertical and peripheral force is applied; Vertical and rotating motion can be simultaneously affected. The result is a vertical and horizontal motion around the upstanding support structure. The introduction of a locking ring will restrict horizontal rotational motion when a pin is inserted through the 2″×4″×X′ beam and the locking ring. If only vertical rocking movement is desired, a pin can be inserted through the 2″×4″×X′, the locking ring, and the vertical stanchion of the tripod restricting horizontal rotating movement.
DESCRIPTION OF MAIN COMPONENTS
FIG. 1: Tripod receiver rocker arm acts as the lever arm. A pivoting assembly that sits over top of the vertical stanchion of the tripod base. The rocker arm manually rotates horizontally and manually moves up and down in a vertical motion. The receiver also has a plurity of offsetting mounting slots in order to balance the loading of different weights on opposite ends of the teeter totter. The view in FIG. 1 is from a elevated side view.
FIG. 2: A locking ring in which a pin can be inserted to restrict rotational or vertical movement. The view in FIG. 2 is from an elevated side view.
FIG. 3: Tripod base a vertical stanchion fixedly coupled to the legs and extending upwardly there from. The view in FIG. 3 is from a elevated side view.
FIG. 4: An elevated side view of the three parts inserted together. The view also shows one of three legs inserted into the tripod base thereof.
FIG. 5: An upside down, side cross section plan view of the tripod thereof.
FIG. 6: A bottom plan view of the tripod thereof.
FIG. 7: A 90 degree counter clockwise side plan view of the tripod thereof.
FIG. 8: An upside down view of the receiver rocker arm thereof.
FIG. 9: A plan side view of the receiver rocker arm thereof.
FIG. 10: A side end plan view of the receiver rocker arm thereof.
FIG. 11: A exploded assembly view of the teeter totter thereof.
FIG. 12: A exploded assembly view of the tripod receiver rocking arm thereof.
FIG. 13: A exploded assembly view of the locking ring thereof.
FIG. 14: A exploded assembly view of the tripod base thereof.
