Protective ring for toy helicopter

Abstract

A helicopter having increase stabilization and protective rings for the propellers is provided. The helicopter includes a helicopter body, and at least one propeller connected by a shaft to the helicopter body. The at least one propeller is configured to rotate in a first direction about an axis defined by the shaft. A protective ring is pivotally connected to the at least one propeller at pivot points positioned at opposing ends thereof. The protective ring rotates with the at least one propeller and is pivotable about a longitudinal axis defined by the at least one propeller, such that the protective ring pivots independent of a tilting angle of the propeller.

What is claimed is: 
     
         1 . A helicopter, comprising:
 a helicopter body having a rotating shaft;   a propeller connected to the shaft, and being configured to rotate about an axis defined by the shaft in a first direction, the propeller having opposing ends and a longitudinal axis transverse to the shaft axis; and   a protective ring having pivot points configured to connect the protective ring to the opposing ends of the propeller, said protective rotating with the propeller and being capable of pivoting about the longitudinal axis of the propeller independent of a tilting angle of the propeller.   
     
     
         2 . The helicopter of  claim 1 , wherein the pivot points comprise:
 receiving holes in the opposing ends of the propeller;   opposing receiving holes passing through the protective ring; and   rivets configured to pass through the protective ring receiving holes and engage the receiving holes in the opposing ends of the propeller.   
     
     
         3 . The helicopter of  claim 1 , further comprising:
 an additional propeller connected by the shaft above or below the propeller and being configured to rotate about the axis defined by the shaft in a direction opposite the first direction; and   an additional protective ring having pivot points configured to connect the additional protective ring to the opposing ends of the additional propeller, said additional protective ring rotating with the additional propeller and being capable of pivoting about the longitudinal axis of the additional propeller independent of a tilting angle of the additional propeller.   
     
     
         4 . The helicopter of  claim 3 , wherein the additional propeller is positioned above the propeller on the shaft. 
     
     
         5 . The helicopter of  claim 4 , further comprising a stabilizer connected to the additional propeller by links. 
     
     
         6 . The helicopter of  claim 5 , further comprising a stabilizer protective ring fixed to the stabilizer. 
     
     
         7 . The helicopter of  claim 5 , wherein the stabilizer is positioned above the additional propeller. 
     
     
         8 . The helicopter of  claim 5 , wherein the stabilizer is positioned below the additional propeller. 
     
     
         9 . A helicopter, comprising:
 a first propeller connected by a shaft to a helicopter body, and being configured to rotate in a first direction about an axis defined by the shaft, the first propeller having opposing ends and a longitudinal axis transverse to the shaft axis;   a second propeller connected to the shaft above the first propeller, and being configured to rotate in a direction opposite the first direction about the shaft axis, the second propeller having opposing ends and a longitudinal axis transverse to the shaft axis;   a first protective ring connected to the opposing ends of the first propeller; and   a second protective ring having pivot points configured to pivotally connect the second protective ring to the opposing ends of the second propeller, said second protective ring rotating with the second propeller and being capable of pivoting about the longitudinal axis of the second propeller independent of a tilting angle of the second propeller.   
     
     
         10 . The helicopter of  claim 9 , wherein the pivot points comprise:
 receiving holes in the opposite ends of the second propeller:   opposing receiving holes passing through the second protective ring; and   rivets configured to pass through the second protective ring opposing receiving holes and engage the receiving holes in the opposing ends of the second propeller.   
     
     
         11 . The helicopter of  claim 9 , further comprising a stabilizer connected to the second propeller by links. 
     
     
         12 . The helicopter of  claim 11 , further comprising a third protective ring fixed to the stabilizer. 
     
     
         13 . The helicopter of  claim 11 , wherein the stabilizer is positioned above the second propeller. 
     
     
         14 . The helicopter of  claim 11 , wherein the stabilizer is positioned below the second propeller. 
     
     
         15 . A helicopter, comprising:
 a helicopter body having a rotating shaft;   a first propeller connected to the shaft, and being configured to rotate about an axis defined by the shaft in a first direction, the first propeller having opposing ends and a longitudinal axis substantially transverse to the shaft axis;   a second propeller connected to the shaft and positioned above the first propeller, the second propeller being configured to rotate in a direction opposite the first direction about the shaft axis, the second propeller having opposing ends and a longitudinal axis substantially transverse to the shaft axis;   a first protective ring having pivot points configured to pivotally connect the first protective ring to the opposing ends of the first propeller, the first protective ring rotating with the first propeller and being capable of pivoting about the longitudinal axis of the first propeller independent of a tiling angle of the first propeller; and   a second protective ring fixed to the opposing ends of the second propeller.   
     
     
         16 . The helicopter of  claim 15 , wherein the pivot points comprise:
 receiving holes in the opposing ends of the first propeller;   opposing receiving holes passing through the first protective ring; and   rivets configured to pass through the protective ring receiving holes and engage the receiving holds in the opposing ends of the first propeller.   
     
     
         17 . The helicopter of  claim 15 , further comprising a stabilizer connected to the second propeller by links. 
     
     
         18 . The helicopter of  claim 17 , further comprising a third protective ring fixed to the stabilizer. 
     
     
         19 . The helicopter of  claim 17 , wherein the stabilizer is positioned above the second propeller.
