ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a toy airplane that flies when thrown into the air, and more particularly to such a toy airplane, which is made by clamping component parts to one another that are obtained from a sheet member by stamping.
FIGS. 1 and 2
show a prior art toy airplane that flies when thrown into the air. This structure of toy airplane is comprised of a fusclage
1
, a main wing
4
, and an elevator
5
. The fuselage
1
comprises a wing slot
2
, an elevator slot
3
, and a vertical stabilizer
6
. The main wing
4
and the elevator
5
are respectively fastened to the wing slot
2
and the elevator slot
3
. This structure of toy airplane has numerous drawbacks as outlined hereinafter.
1. The whole design of the toy airplane is monotonous and less attractive. This design does not allow additional airplane accessories to be attached to the fuselage or the main wing.
2. Because the main wing and the elevator are respectively plugged into the wing slot and the elevator slot and no retainer means is provided to secure the connection between the fuselage and the main wing/elevator, the main wing or elevator may fall out of the fuselage when the toy airplane is thrown into the air.
3. The limited area of the main wing and the elevator cannot help the toy fuselage fly in the air for long.
4. This design of toy airplane cannot be equipped with a delta wing.
If a long wing slot is made on the fuselage for the installation of a delta wing, the structural strength of the fuselage will be destroyed.
SUMMARY OF THE INVENTION
It is one object of the present invention provides a toy airplane, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide a toy airplane, which has a strong structural strength. It is another object of the present invention to provide a toy airplane, which is equipped with a delta wing and a tail fin. It is still another object of the present invention to provide a toy airplane, which is equipped with elevators for a long flight in the air. It is still another object of the present invention to provide a toy airplane, which is equipped with auxiliary wings for long fly in the air. It is still another object of the present invention to provide a toy airplane, which is equipped with a heavy nose that keeps the toy airplane in balance when flying. According to one aspect of the present invention, the toy airplane comprises s a fuselage and a main wing fastened to the fuselage. The fuselage comprises a top clamping strip at a front side thereof, a vertical stabilizer at a rear side thereof, a plug strip spaced between the top clamping strip and the vertical stabilizer, a first retaining notch disposed between the top clamping strip and the plug strip, and a second retaining notch disposed between the plug strip and the vertical stabilizer. The main wing comprises two parallel front tips attached to the top clamping strip of the fuselage at two opposite sides, a first retaining notch longitudinally extended to a front side thereof and defined between the front tips and forced into engagement with the first retaining notch on the fuselage, a second retaining notch longitudinally extended to a rear side thereof and forced into engagement with the second retaining notch on the fuselage, and an elongated plug hole longitudinally disposed on the middle and engaged with the plug strip of the fuselage. Because the plug strip of the fuselage is plugged into the plughole on the main wing from the bottom side and the top clamping strip and stabilizer of the fuselage are respectively clamped on the topside of the main wing, the connection between the fuselage and the main wing is stable. According to another aspect of the present invention, the main wing is a delta wing. According to still another aspect of the present invention, the main wing comprises two third retaining notches bilaterally disposed near the rear side thereof, and two auxiliary wings are respectively fastened to the third retaining notches on the main wing to improve the floating ability of the toy airplane in the air. According to still another aspect of the present invention, a retaining strip is secured to the second retaining notch on the fuselage and supported on the main wing to reinforce the connection between the stabilizer of the fuselage and the main wing. According to still another aspect of the present invention, a heavy nose is fastened to the front end of the fuselage to keep the toy airplane in balance.
