Abstract

The toy airplane is comprised of laminar parts which are provided with a plurality of differentiated regular and irregular orifices and grooves for receiving and setting in place said laminar parts as well as the corresponding counterweights which modify the flight characteristics of the airplane, one of said counterweights being comprised of a spherical body which has a peripheral groove which may be provided with additional counterweights and which, in its turn, may be introduced in a sheath passing through an orifice of the fuselage.

Description

TOY AIRPLANES

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, consists of improvements introduced in the assembly of toy airplanes, based on their components, whose main purpose lies in the fact of allowing to modify the flight characteristics, in depending on the number and place of counterweights that are available in a series of accommodations provided in the fuselage of the aircraft.

Another additional object of the invention is to allow different combinations between fuselages and wings, varying the aesthetics, and also the way of flight of the plane, according to the user's taste.

BACKGROUND OF THE INVENTION

Conventionally, the removable airplanes of the type of those that are constituted by laminar portions, only allow a combination of their elements, which establishes that only a structure of them and a single form of flight can be obtained, whose characteristics can be varied very slightly

This determines a limitation in terms of its use and design.

In addition, the material used in the manufacture of these aircraft prevents their use inside

SUBSTITUTED SHEET of a dwelling, since when hitting an object there is a certain probability that it may be damaged, which constitutes an inconvenience and a limitation in its use.

DESCRIPTION OF THE INVENTION

In order to solve the aforementioned drawbacks, the invention determines the possibility of mounting different wings in different fuselages, allowing the choice of the structure of the plane, while on the fuselages a series of housings are provided in which it is capable of being housed differently. Counterweights, whose shape and location allow modifying the flight conditions of the plane.

In order to achieve these objectives, the corresponding grooves are provided on the fuselages of the plane that allow the assembly of the wings.

In addition, on the fuselages there is included, in the area corresponding to the "nose", a hole following which another irregularly shaped hole is provided, whose structure resembles that of a drop of water in which its narrow area is slightly arched and runs along the bottom swk fuselage.

In the area corresponding to the groove in which the wings or planes are located, a hole is provided, centered and in its anterior area, followed by a plurality of small semicircular holes facing both sides of the groove.

Likewise, a hole is provided on the wings that is arranged in correspondence with the hole

SUBSTITUTED SHEET included in the front part of the grooving, to allow the introduction of a counterweight.

One of the counterweights is constituted by a spherical body that is capable of including a perimetric groove; for its introduction in the holes provided in the "nose" of the plane and in the front part of the groove in which the wings are included.

In addition, there is an annular counterweight that is arranged in the small semicircular holes provided on both sides of the groove in which the wings are included, thus leaving the annular counterweight, attached to the upper or lower part of the wing.

Likewise, in the small holes, weights can be introduced in bars of different lengths that are arranged attached to the upper or lower part of the wing.

On the other hand there is a counterweight in the form of a drop of water, curved by its narrowest part, for inclusion in the hole in the same way provided in the fuselage.

It should be noted that spherical counterweights are likely to be introduced into a quadrangular sheath equipped with a through hole for incorporation into the fuselage; for which the holes in the fuselage have a quadrangular shape, so that the counterweight is perfectly hidden.

In order to facilitate a better understanding of this descriptive report and being an integral part of it, a series of figures are accompanied in which

DESCRIPTION OF ÜNO OR VARIOUS EXAMPLES OF EMBODIMENT OF THE INVENTION

Below is a description of the invention based on the figures mentioned above.

The invention at hand refers to the assembly of toy airplanes, of the type that are constituted from laminar portions.

Thus, the invention contemplates the possibility of using two fuselages 1 and 2, slightly different, but compatible with each other, for which they include the grooves 3 and 4 of inclusion of the different wings.

In the exemplary embodiment, the possibility of mounting on the groove 3 two different wings 9 and 11, both provided with the hole 10, whose function will be explained later, has been contemplated.

Similarly, in the exemplary embodiment, the possibility of mounting three different wings 12, 14 and 15 in the groove 4 has been contemplated, the 12 being provided at its ends with recesses for the introduction of planes 13.

SUBSTITUTED SHEET Therefore, in the embodiment example two fuselages are used, two different types of front wings and three different types of rear wings, allowing any kind of combination to be made between them.

In addition, the fuselages 1 and 2 are provided in the area corresponding to the "nose" of a hole 5, preferably circular, following which another irregularly shaped hole 6 is provided that resembles a drop of water, in which The narrow area is slightly arched and runs along the bottom of the fuselages 1 and 2.

In addition, in both fuselages 1 and 2, and in the front and centrally of the groove 4, a new hole 7 is provided, which is arranged in correspondence with the hole 10 provided in the wings 9 and 11.

Following the hole 7, a plurality of small semicircular holes 8 facing both sides of the slot 3 is included.

Furthermore, the invention has a series of counterweights, one of which is constituted by a spherical body 16 capable of including a perimeter groove 22, to allow its introduction into holes 5 and / or 7.

In addition, the invention has a counterweight 17 in the form of a drop of water curved in its narrowest part, which is capable of being introduced into the irregular hole 6 which has the same shape.

Similarly, counterweight 17 has a channel

SUBSTITUTED SHEET perimeter 18 that facilitates its introduction into the housing 6 indicated above.

Also, it should be noted that the invention has an annular counterweight 21 that is arranged in the small semicircular holes 8, being attached to the upper or lower part of the wing 9 or 11.

In addition, in said small semicircular holes 8, a series of bar weights of different lengths, not shown in the figures, can be introduced, since their structure is extremely simple.

Obviously, in the small semicircular orifices 8 there is the possibility of including spherical weights 16, the diameter of which is adapted to the measure of the said small semicircular orifices.

8.

The spherical counterweights 16 are capable of being introduced into a quadrangular sheath 19 provided with a through hole 20, which is constituted of the same material as that of the aircraft, which is preferably made of a soft and flexible material, preventing it from breaking. , or damage the surfaces or objects that could impact when launched by the user, which determines that the aircraft of the invention can be used inside the user's own home, preventing the objects introduced therein can suffer damage

By allowing the introduction of spherical counterweights 16 in the sheath 19, the foregoing are perfectly hidden and match the structure and materials of the aircraft.

SUBSTITUTED SHEET All the elements described can be assembled in the way the user wishes, so that, for example, if only one counterweight is included in hole 5, the plane will take a plummeting flight, while if, for example , a single annular counterweight 21 is used, the plane will perform a gliding flight, therefore, according to the arrangement of the different weights the variation of the airplane's flight characteristics is allowed, with what the user can experience, including the different counterweights, in the desired way, different forms of flight.

A possible embodiment is shown in Figure 12, in which a counterweight 16 provided inside a quadrangular sheath 19 has been included, which in turn has been introduced inside the hole 5. Furthermore, in this An embodiment of the annular counterweight 21 is provided in the upper part of the wing 20.
