Smart Summary: A modifiable boomerang has two wing blades that are shaped with a curved top and a flat bottom. These wings are connected by a pivot bolt, allowing the angle between them to be adjusted. By changing this angle, the thrower can alter how the boomerang flies and its flight pattern. This design includes a hinge joint at the center, making it easy to modify the angle before throwing. Overall, this boomerang offers more flexibility in its performance compared to traditional fixed-angle boomerangs. 🚀 TL;DR
Abstract:
A modifiable boomerang comprises of a pair of wing blades which have a curved top surface and a flat bottom surface. The wings are connected together by a pivot bolt to form a boomerang whose angle can be adjusted to change the aerodynamics of the flying boomerang. A thrower can change the angle of a boomerang to change its flying pattern.

Description
THE BACKGROUND OF THE INVENTION
An ordinary boomerang has a fixed angle of its wings and its flying course and pattern are heavily influenced by this angle. If we change this angle then its flying course and pattern will change. The present invented modifiable boomerang has a hinge joint installed at its center to allow adjustment of its angle.
THE BRIEF DESCRIPTION OF THE INVENTION
Every boomerang has its wings set at a certain angle. Therefore, it has a certain flying pattern. When the angle of a boomerang changes its flying pattern will change also. The present invented modifiable boomerang is equipped with a hinge joint at the center to allow the thrower to change the angle of the boomerang and thus change the flying pattern of the boomerang.
DETAILED DESCRIPTION OF DRAWINGS
FIG. 1 is perspective view of a modifiable boomerang.
FIG. 2 is perspective view of components of modifiable boomerang.
SPECIFICATION
Referring now to the drawings in detail, numeral 3 of FIG. 1 is a modifiable boomerang.
Numeral 4 of FIGS. 1 and 2 is a top wing blade.
Numeral 5 of FIGS. 1 and 2 is a bottom wing blade.
The top wing blade 4 and bottom wing blade 5 have a top curved surface and a flat bottom surface.
Numeral 6 of FIGS. 1 and 2 are bolt holes.
Numeral 7 of FIGS. 1 and 2 is an adjustment bolt.
Numeral 8 of FIG. 2 is an adjustment nut corresponding to bolt 7.
Numeral 9 of FIG. 2 is a pivot bolt.
Numeral 10 of FIG. 2 is a pivot hole for the pivot bolt 9.
Numeral 11 of FIG. 2 is a pivot nut corresponding to pivot bolt 9. The pivot bolt 9 can pass snugly through pivot hole 10. The pivot nut 11 can screw snugly onto pivot bolt 9.
Numeral 12 of FIG. 1 is an angle made by the top wing blade 4 and bottom wing blade 5 of the modifiable boomerang 3.
The way to assemble the modifiable boomerang 3 is first to align the pivot hole 10 of the top wing blade 4 with the pivot hole 10 of the bottom wing blade 5 and then insert the pivot bolt 9 into the pivot hole 10 and screw on the pivot nut 11 tightly to make a modifiable boomerang 3. The angle 12 of the modifiable boomerang 3 can be set by first loosening the pivot nut 11, then aligning any bolt hole 6 of the top wing blade 4 with any bolt hole 6 of the bottom wing blade 5, then inserting bolt 7 through the bolt hole 6, then screwing on nut 8 tightly, and finally tightening the pivot nut 11. When the angle 12 is changed, the air dynamics of a thrown modifiable boomerang will be changed. Therefore a thrower can change the angle 12 of the modifiable boomerang 3 to change its flying pattern.
Claims
The invention claimed is:1. A modifiable boomerang comprising:
two wing blades, each wing blade having a plurality of bolt holes arranged in a circular ring, each wing blade having a pivot hole located in a center of the circular ring of bolt holes,
one pivot bolt with pivot nut, and
one adjustment bolt with adjustment nut
wherein said pivot bolt is fastened through the pivot hole and secured by the pivot nut and said adjustment bolt is fastened through one of the plurality of bolt holes on each wing blade and secured by the adjustment nut to fasten said wing blades into different angles to change said modifiable boomerang's flight pattern.
2. The modifiable boomerang of claim 1 wherein both wing blades have a curved top surface and a flat bottom surface.
