Thein [5 7] ABSTRACT Self-propelling aquatic toy, for example a fish adapted to swim in water, having a body portion and a tail portion, the latter including a driven intermediate and a non-driven terminal member, the former being swiveled by an electric motor within the body portion, while the terminal tail member is limp and freely pivotable with respect to the intermediate tail member, so that the toy performs a life-like swimming" movement in the water, the terminal member swiveling in a direction opposite to the movement imparted to the intermediate member.
10 Claims, 5 Drawing Figures SELF-PROPELLING AQUATIC TOY The invention relates to a self-propelling aquatic toy, for example in the form of a swimming fish, and mainly concerns its propulsion system.
It is one of the major objects of the invention to provide a self-propelling toy adapted to swim in water, characterized by life-like movements and fast propelling action.
According to the major features of the invention, the self-propelling aquatic toy comprises a body portion and a tail portion, the latter including a driven intermediate and a non-driven terminal member, respectively linked to one another about pivotal axes parallel with one of the horizontal and vertical, longitudinal center planes of the body portion. The intermediate portion is driven by means of an electric motor, by the intermediary of a linkage, the latter including, as a matter of example, a lever of extension having a slot therein, a crank rotated by the motor being slidable in the slot while the linkage is oscillated. The intermediate tail portion is directly swivelled by the drive means, preferably by the aid of a frame member extending throughout said portion, while the terminal portion is freely pivotable with respect to the intermediate portion, and will move in opposite directions, as a result of water resistance and the laws of hydrodynamics.
Either an articulation or a flexible zone may be provided between the body and the intermediate portion, on the one hand, and between the latter and the terminal portion, on the other. The body of the toy is preferably made from a substantially rigid, waterimpermeable material, while the intermediate portion is of a soft, such as foamed material, with a similarly water-impermeable skin thereon.
At least one fin may be provided, such as on the belly of the toy, for stabilizing the same in the water. The plane of the fin, or fins, if there are more, is preferably parallel with the pivoting axes of the tail portions.
Other objects, features and many of the attendant advantages of the invention will be readily appreciated as the same becomes better understood by reference to the following detailed description, when considered with theaccompanying drawings, wherein FIGS. 1 and 2 are somewhat schematic perspective side views of an exemplary embodiment of the selfpropelling aquatic toy according to the invention, in the form of a fish, with the tail thereof shown in respective extreme swivelled positions;
FIGS. 3 and 4 are top elevations of the toy, corresponding to the respective positions thereof as shown in FIGS. 1 and 2; and
FIG. 5 is a partly sectional side view showing the inner propelling mechanism of the aquatic toy according to FIGS. 1 to 4.
In its illustrated, preferred exemplary form the selfpropelling aquatic toy has the form of a fish adapted to swim in water having a body portion 1 and a tail 2 designed to perform wriggling or tailing movements. The latter includes an intermediate link or member 3 and a terminal or end member 4. Intermediate member 3 is linked, on the one hand, with body 1 and, on the other hand, with end member 4 by respective pivot lines or axes 5 and 6, substantially parallel with the ver tical or horizontal longitudinal center planes of body 1.
Either an articulation or a soft zone is provided between the respective members (body and intermediate member, and the latter and terminal member). The
body itself preferably consists of a substantially rigid, water-impermeable material, while the intermediate member is of a soft material, preferably with a similarly water-impermeable skin thereon.
The fish body may be provided with a belly fin 7, or with more fins as shown in FIGS. 1 and 2 as well as 5, preferably made from metal, having a size and weight such that the aquatic toy sinks to about two-thirds of its height below the level of the water body in which it is immersed so that its swimming position is stabilized as necessary.
As can be seen from FIGS. 1 to 4, wriggling tail 2 can be swiveled between the extreme positions shown in FIGS. 1 and 3 as well as 2 and 4, respectively, corresponding to a considerable degree to the natural movements of living fish, which allows the forward movement of the aquatic toy.
As will be explained in connection with the propelling mechanism illustrated in FIG. 5, intermediate tail member 3 is moved with respect to body 1 from one side to the other, namely about pivot or axis 5, thereby impelling end member 4 to carry out a swinging or p'ivoting movement in the opposite direction, as a result of the resistance of the surrounding water, whereby the toy is propelled as necessary and performs a swimming action.
FIG. 5 illustrates the actual propelling mechanism inside the body of the toy, the body being constructed as was explained before. The mechanism inside body 1 includes an electric motor schematically shown at 8, rotating a crank 9 at an approximate speed of two to four revolutions per second, namely about four revolutions when out of water, depending on the condition of the driving battery or batteries, and normally about 2.5 revolutions when immersed in the water and propelling the toy.
Crank 9 engages a longitudinal slot 10 on the inner or free end of a lever member or extension 11. The latter is provided on a preferably metallic frame member 12 within intermediate tail member 3, rotatably or pivotally journaled in a simple bearing 13 on the adjoining end of fish body 1, in axis 5, but extending over the entire length of member 3, that is all the way to axis 6, as illustrated.
Motor 8 can be designed for 1.5 to 4.5 volts DC, fitted with customary small-size (sometimes called penlight") batteries for toys and the like (omitted from FIG. 5 for the sake of clarity but self-explanatory for toys of this kind).
When motor 8 is energized, crank 9 rotates with the above-mentioned speed, thereby swinging metal frame 12 by the intermediary of lever 11, through engagement with and sliding action along slot 10 of the latter, about bearing 13. A back-and-forth oscillation or swinging movement results so that the driven intermediate member 3 performs a pendulum-like or wriggling movement, with the non-driven terminal member 4 swinging in the opposite direction. The fish-shaped toy will thus perform a life-like and fast forward swimming movement in a most convincing fashion. Should the fish swim against the wall of a tank, the oscillating movement of the tail members will soon get the toy free so that the self-propelling movement can continue in another direction.
It might be added that in its practical, exemplary form, the self-propelling aquatic toy has a specific weight of about 0.7. Two-thirds of the fish body are normally under water. The positioning and safe propelling are ensured by the arrangement of all inner structural members in a symmetrical manner, including batteries and motor. Walls and other parts of the toy are kept uniform so as not to impair the required balance. The fin or fins are adapted to enhance stability.
It should be understood, of course, that the foregoing disclosure relates only to a preferred embodiment of the inventive toy and that it is intended to cover all changes and modifications of the example described which do not constitute departures from the spirit and scope of the invention.
