FIELD OF THE INVENTION

This invention relates to toys with retractable wings or similar extensions. BACKGROUND

In the field of toys, it is known to have retractable wings or similar extensions. Owing to the materials and the structures used, however, such wings had the tendency to break when extended, or to bend unduly, or to be overly heavy to avoid such breakage. For example, resistance to breakage in the prior art has been effected by making the wings out of soft or elastic material such as foam or rubber, with the unavoidable side effect of being unable to provide a crisp and precise wing deployment and a long wing that would not wobble. Alternatively, a rigid, long, crisp and breakage-resistant toy wing construction is known in the prior art but it generally involves either using thin and very expensive materials of construction, or using extra thick, less expensive materials that impart undue bulkiness to the toy.

Accordingly, it would be desirable to have a toy with wings which avoided these problems with prior art toys. In particular, it would be desirable to have a toy with folding and retractable wings that could be simultaneously:

- crisp and precise in their deployment (folding, unfolding, retracting, extending);

- long, wide, thin and lightweight;

- of a high longitudinal rigidity when extended;

- unobtrusive and compact when folded and retracted;

- resistant to breakage or permanent deformation upon abusive bending/twisting and upon high energy impact with hard surface;

- amenable to tool-less, fool-proof, snap-in-place assembly and disassembly;

- amenable to push-button, instant deployment;

- difficult to misplace or lose when disassembled from the toy body;

- made of common and inexpensive plastics that are economical to manufacture and easy to process.

SUMMARY OF THE INVENTION

The present invention answers, to a substantial degree, the long felt need for folding and retractable toy wings that combine all of the above mentioned desired characteristics into one package.

Accordingly, in a principal aspect of the present invention, a toy is provided with folding and retractable wings that are:

- crisp and precise in their deployment (folding, unfolding, retracting, extending);

- long, wide, thin and lightweight;

- of a high longitudinal rigidity when extended; - unobtrusive and compact when folded and retracted;

- resistant to breakage or permanent deformation upon abusive bending/twisting and upon high energy impact with hard surface;

- amenable to tool-less, fool-proof, snap-in-place assembly and disassembly;

- amenable to push-button, instant deployment;

- difficult to misplace or lose when disassembled from the toy body;

- made of common and inexpensive plastics that are economical to manufacture and easy to process.

These and other aspects and advantages of the present invention will be apparent to those skilled in the art upon consideration of the following detailed description in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Figure 1 shows a toy 2 in accordance with a preferred embodiment. The toy 2 has a body 4, a head 6 with a space helmet 8, two arms 1OA, 1OB, two legs 12A, 12B, and two folding and retractable wings 14 A, 14B. When folded and retracted as shown in Figure 1 , the wings 14A, 14B are nested one under the other on the back of the toy 2. A backpack cover 16 substantially covers the wings 14A, 14B in their nested position, to hide the folded wings from sight and to impart a more esthetically pleasing and streamlined look to the toy 2.

As shown in Figure 9, the backpack cover 16 has an outside surface 18, and an inside surface 20 normally facing the wings 14A, 14B. In alternative embodiments, the backpack cover 16 can be absent, without substantially affecting the functioning of the toy 2.

In the preferred embodiment shown in Figures 4 to 6, the backpack cover 16 is positioned on the toy body so as not to impede the deployment (folding, unfolding, retracting, extending) of the wings 14A, 14B. As shown in Figures 9A and 9B, the backpack cover 16 has, attached to its inside surface 20, two pins 22A, 22B with spherical heads 24A, 24B. The spherical heads 24 A, 24B releasably snap into appropriately sized respective resilient receptacles 26A, 26B fixed on the back of the toy body, to hold the backpack cover 16 in place. When access to the folded wings 14 A, 14B and to the back of the toy body is desired, for example in order to access a battery compartment door or battery pack cover 28, the backpack cover 16 can be relatively easily snapped off by the application of an outward pulling force. The backpack cover 16 can be snapped back on by the application of a pushing force. The backpack cover 16 can also snap off by itself, without breakage, should the wings themselves snap off from the body for example resulting from abusive bending/twisting, or from high energy impact with a hard surface such as occurs when dropped on the floor.

Each individual wing 14A, 14B has an underside surface piece 3OA, 3OB and a top surface piece 32A, 32B. The respective underside pieces 3OA, 3OB have a respective underside piece aperture 34A, 34B. The respective top surface pieces 32A, 32B have a respective top surface piece aperture 36A, 36B. The respective underside surface pieces 3OA, 30B are connected to the respective top surface pieces 32A, 32B with the respective apertures aligned. The wings 14A, 14B can pivot about articulation posts 38A, 38B which are positioned through the respective apertures to connect the respective wings 14A, 14B with the back of the toy body.

The wings 14A, 14B have respective wing tip sections 4OA, 4OB which slidably extend or retract from a space formed between the respective underside surface piece 30A, 30B and respective top surface piece 32A, 32B.

Several springs, latches and stopping mechanisms cooperate to define two stable angular positions of each wing 14A, 14B relative to the longitudinal axis of the body: a folded and an unfolded position. In the folded position shown for example in Figures 1 and 3, a wing's longitudinal (base to tip) axis is generally aligned with the longitudinal axis of the toy body. In the unfolded position shown for example in Figure 2, a wing's longitudinal (base to tip) axis is generally at a transverse angle with the longitudinal axis of the toy body, resembling the position of an airplane wing relative to an airplane's body. The springs impart to the wings 14A, 14B a permanent bias toward the unfolded position, while the folding latches serve to retain the wings locked into the folded position. When folded, the wings are thus spring-loaded, and will spring into the unfolded position when the folding latches disengage.

For increased compactness with both wings 14 A, 14B in the folded position, the pivoting articulations between the wings 14A, 14B and the body 4 allow and impart a slight movement on a direction perpendicular to the wings' angular rotation plane. When one wing is angularly rotated on its pivot towards its folded position, its pivot slides axially inward towards the body of the toy, to bring the folded wing slightly closer to the back surface of the toy. When the second wing is angularly rotated on its pivot towards its folded position, its pivot slides axially outward from the body of the toy, to bring the second folded wing slightly away from the back surface of the toy. The combined result of the two acts described above is that, when folding both wings, one wing is able to slide under the other wing and nest compactly thereunder. This helps maintain a streamlined body profile while accommodating wider wings on a narrower body, due to the increase in compactness of the wings' folded configuration.

Independent from its angular position (folded/unfolded), each individual wing 14A, 14B is also retractable in length. Each wing is of a telescopic construction and consists of two sections: the base section, comprising the respective underside surface pieces 30A, 30B and the top surface pieces 32A, 32B and the tip section which telescopes from within the base section. Several springs, latches and stopping mechanisms cooperate to define two stable states for each wing: a retracted state, for example shown in Figure 1, and an extended state, for example shown in Figures 2 and 3. The extension springs impart to each wing a permanent telescoping bias toward the extended state, while the retraction latches serve to retain a wing locked into the retracted state. The retraction latches have release levers which protrude from the wing surface and which, when engaged, can release the latches and cause a wing to spring into its extended state. To engage these release levers, appropriately sized knobs and protuberances are provided on the inside face of the backpack cover and/or on the back of the toy body. The knobs and protuberances are positioned so as to catch and engage the release levers on the wings during the sweeping movement of the wings into their unfolded position.

In a preferred embodiment, such as illustrated in Figure 12, a user triggers the unfolding of the wings 14A, 14B by pressing a button 60 on a chest 62 of the toy to release the latch that holds the spring-loaded wings in the folded position. Once the unfolding of the wings 14A, 14B is underway, appropriately sized knobs and protuberances, positioned at certain places on the backpack cover and/or on the back of the toy body, engage the release levers of the retraction latches on each wing, and automatically cause each wing to telescopically expand to its full extended length, without any extra input from the toy user. In a preferred embodiment, one wing has its retraction latch release lever on the underside surface of the wing (facing the back of the toy body) so that it could be engaged by a knob placed on the body of the toy. The other wing has its release lever on its top surface (facing the backpack cover) so that it could be engaged by a knob placed on the inside face of the backpack cover. In alternative embodiments, the wings 14A, 14B can have their retraction latch release levers on either their underside or on their top surfaces, so as to be able to engage the corresponding knobs placed either on the inside of the backpack cover or on the body of the toy.

In an alternative embodiment, there is no button to trigger the spring-loaded unfolding of the wings 14A, 14B, and the user has to initiate the unfolding by pulling each wing outwardly until the latches on each wing disengage and each wing proceeds to complete its spring-loaded unfolding, followed by spring-loaded wing expansion into its extended state, as described in the previous paragraph.

In another alternative embodiment, the tips of the wings have operational electric light- bulbs or LEDs. Thin, flexible electrical cables, routed through the interior space of each wing, connect the wingtip lights with the battery pack located preferably within the body of the toy. Integrated circuit means, also located preferably within the body of the toy, can be used to control the operation of the wingtip lights and of various other body lights and accompanying sounds. In another alternative embodiment, there is no integrated circuit, and simple contact switches turn on the wingtip lights upon wing deployment and turn off the lights when the wings are folded and retracted.

Retracting and folding back the wings 14A, 14B is done manually in all embodiments, by rotating each wing inward until the folding latches on each wing engage, followed by pushing the tip section of each wing into its base section until the retraction latches on each wing engage.

The pivoting articulations between the wings and the toy body are constructed to allow snap-in-place assembly and disassembly of the articulation, without the need to use any tools or an excessive force beyond what a typical user of the toy (a child) would possess. The pivoting articulations are constructed to withstand high mechanical stress and to provide crisp, precise movement during wing unfolding, as well as robust rigidity during energetic operation of the toy with the wings in a fully extended position. However, the pivoting articulations between the wings and the toy body are designed to automatically release the wings from the pivot articulation in the event that the mechanical stress load would approach a level that could cause breakage or destructive disassembly of the wing components, such as upon abusive bending/twisting, dropping the toy on the floor, or other high energy impact with a hard surface. The backpack cover 16 is also designed to snap off whenever one of the wings 14A, 14B is released from the pivot articulation, thus ensuring that a wing 14 A, 14B becomes non-destructively detached from the toy body well before the stress load would cause that wing 14A, 14B to break.

This precise, non-destructive, safety release action allows the toy to be fitted with long, thin and lightweight rigid wings constructed of common and inexpensive plastics, yet it allows the toy to pass all safety and drop tests designed to ensure that the toy is resistant to breakage or that its breakage will not result in sharp edges. After any incident resulting in such a safety release of a wing from the pivot articulation, the toy can be easily reassembled into its original configuration by snapping back in place any part that previously snapped off, for example the wings 14A, 14B or the backpack cover 16. Furthermore, in a preferred embodiment such as shown in Figure 7, the respective wings 14A, 14B are unobtrusively tethered to the body by a length of thin string 5OA, 5OB that ensures that a detached wing cannot be lost, misplaced or taken away from the general proximity of the toy 2. In an alternative embodiment, the tethering string 50A, 50B can be omitted. In another alternative embodiment, the reinforced, thin, electrical wires connecting the wingtip lights with the battery pack inside the toy's body can also serve the role of tethers for the wings.

It will be apparent to those skilled in the art, after reviewing this description, that many changes, modifications, variations and other uses and applications for the subject folding and retractable wing toy, in addition to those which have been disclosed are possible and contemplated, and all such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention which is limited only by the claims which follow.
