Abstract
A toy airship includes an elongated hull having a generally. circular cross section which includes a pair of panels. The panels are movably supported with respect to the remainder of the airship hull by a plurality of pivotally supported arms. The interior ends of the pivotally supported arms are secured to a movable slide which is positioned by a return spring so-as-to pivot the supporting arms of the panels forwardly and outwardly thereby extending the movable panels to reconfigure the toy airship in a hydrofoil craft configuration. A movable button is operative coupled to the slide and is used to drive the slide forwardly against the return spring and thereby pivot the panel supporting arms rearwardly and inwardly. As the arms are pivoted rearwardly and inwardly, the panels are configured into a closed position resulting in reconfiguring the toy airship in its airship resembling configuration.
Description




FIELD OF THE INVENTION




This invention relates generally to toys capable of multiple appearances and configurations and particularly to those in which the alternate configurations form distinct types of vehicles.




BACKGROUND OF THE INVENTION




Toys which are capable of transformation between alternate shapes or configurations are well known in the art. Typically, such alternately configurable toys are formed of a plurality of components which are variously coupled and articulated to be moved into alternative positions relative to each other. In most such toys, the alternate configurations result in different shapes and characters for the toy. Most such alternately configurable toys are formed of molded plastic elements which are often highly detailed and which produce distinctly different types of toys in their alternate configurations. Thus, for example, such toys often are alternately configurable between some type of vehicle and some type of fanciful creature such as a robot. Still others, are provided which produce alternate configurations which are both vehicles but which are vehicles but which are vehicles of decidedly different character such as an airplane transformable into a truck or the like.




Notsurprisingly, such alternately configurable toys have been provided in many varieties and types by practitioners in the art. For example, U.S. Pat. No. Des.295,994 issued to Matsumoto sets forth a RECONFIGURABLE TOY AIRCRAFT CARRIER having a plurality of articulated components transformable between a toy robot and an aircraft carrier and further transformable into an aircraft.




U.S. Pat. No. Des.287,037 issued to Matsushiro sets forth a CHANGEABLE ROBOT TOY alternately configurable between a robot and an aircraft.




U.S. Pat. No. Des.287,378 issued to Ohno sets forth a RECONFIGURABLE JET PLANE TOY alternately configurable between an aircraft, a tank and a fanciful robot.




U.S. Pat. No. Des.289,426 issued to Lim sets forth a RECONFIGURABLE TOY ROBOT alternately configured as an aircraft or a robot.




U.S. Pat. No. Des.290,480 issued to Maruyama sets forth a RECONFIGURABLE TOY AIRPLANE alternately configurable between a robot and a toy airplane.




U.S. Pat. No. Des.290,481 issued to Kitamura sets forth a RECONFIGURABLE TOY BOAT transformable between a robot and a hovercraft type boat.




U.S. Pat. Nos. Des.293,803 and 293,804 both issued to Doi each set forth similar RECONFIGURABLE TOY JET PLANES which alternately form between a jet plane and a robot.




U.S. Pat. No. Des.293,805 issued to Matsumoto sets forth a RECONFIGURABLE TOY JET PLANE capable of alternate configuration between a jet plane and a robot.




U.S. Pat. No. Des.293,806 issued to Shibukawa sets forth a RECONFIGURABLE TOY SPACE SHUTTLE capable of alternate configuration between a space shuttle and a robot.




U.S. Pat. No. Des.297,038 issued to Ohno sets forth a RECONFIGURABLE TOY VEHICLE TANKER capable of alternate configuration between a toy robot, a toy jet airplane a tanker type truck toy.




U.S. Pat. No. Des.303,411 issued to Matsuda sets forth a RECONFIGURABLE TANK AND JET ASSEMBLY TOY capable of alternate configuration between a robot-type toy and a jet aircraft and mobile launcher device.




British patent 288,895 issued to White; U.S. Pat. No. 1,561,721 issued to Humphrey; U.S. Pat. No. Des.288,216 issued to Jensen and U.S. Pat. No. Des.86,219 issued to Collette set forth various toy airships and balloons of different designs. Additional toy balloons and airships are shown in German patent 6512 issued to Wagemann and British patent 46855 also issued to Wagemann. Further toy airships and balloons are shown in French patent 433,269 issued to Glaubitz and French patent 396,087 issued to Grimm as well as U.S. Pat. No. 4,799,914 issued to Hutchinson.




U.S. Pat. No. 3,092,060 issued to Reid sets forth a FLYING SUBMARINE having a submarine-like fuselage which supports a pair of retractable wings.




U.S. Pat. No. 4,681,554 issued to Hsien-yang sets forth a TOY DEVICE WHICH CAN BE OPENED AND POSITIONED AT ANY DESIRED ANGLE in which a toy space shuttle includes a pair of openable and closeable cargo compartment doors.




U.S. Pat. No. Des.329,886 issued to Fugitani sets forth an AIR CUSHION BOAT TOY while U.S. Pat. No. 5,297,759 issued to Tilbor et al. sets forth a ROTARY AIRCRAFT PASSIVELY STABLE IN HOVER.




While the foregoing described prior art devices have to some extent improved the art and in some instances enjoyed commercial success, there remains nonetheless a continuing need in the art for ever more improved, interesting and amusing toys capable of alternate configurations.




SUMMARY OF THE INVENTION




Accordingly, it is a general object of the present invention to provide an improved toy capable of alternate configuration. It is a more particular object of the present invention to provide an improved toy capable of alternate configuration which operates in response to a single movable actuating member.

DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

sets forth a perspective view of a toy airship constructed in accordance with the present invention and generally referenced by numeral


10


. Toy airship


10


includes an elongated hull


11


having a pair of movable panels


20


and


21


(panel


21


seen in FIG.


2


). Toy airship


10


further includes a plurality of simulated guiding fins including a vertically extending tail fin


14


as well as horizontal fins


15


and


19


(fin


19


seen in FIG.


3


). Panel


20


is joined to the remainder of hull


11


along an edge


12


and an edge


17


. As is better seen in

FIG. 2

, panel


21


is similarly joined to the remainder of hull


11


along an edge


18


and edge


17


. In accordance with the typical fabrication of a toy airship, toy airship


10


further includes a simulated pilots cabin


13


on the under side thereof.




In accordance with an important aspect of the present invention, hull


11


further supports a movable push-button


16


extending rearwardly from hull


11


. In accordance with the operation of the present invention toy set forth and described below, toy


10


assumes the closed configuration defining a toy airship as shown in

FIG. 1

so long as push-button


16


is forced inwardly into hull


11


. In further accordance with the present invention, and as is set forth below in

FIG. 2

, the release of push-button


16


by the user allows the operative mechanism described below in

FIGS. 3 through 5

to reconfigure toy


10


to the hydrofoil craft configuration shown in FIG.


2


. In further accordance with the present invention, the child user returns toy


10


to the closed airship resembling configuration shown in

FIG. 1

by again forcing push-button


16


inwardly into hull


11


.





FIG. 2

sets forth a perspective view of toy airship


10


in its alternate configuration in which it resembles a hydrofoil watercraft. As described above, toy


10


includes an elongated hull


11


having edges


12


,


17


and


18


formed therein and further including a pair of movable panels


20


and


21


. Panels


20


and


21


are shaped and sized to form the completion of the outer surface of hull


11


in the airship configuration shown in FIG.


1


. Panels


20


and


21


are further configured to define downwardly facing convents curved surfaces which lend further realism to a hydrofoil-type craft. As is also described above, hull


11


further supports a vertical tail fin


14


and horizontal tail fins


15


and


19


(fin


19


seen in FIG.


3


).




With panels


20


and


21


extending outwardly as shown in

FIG. 2

, hull


11


exposes an interior cavity


23


within which a simulated hydrofoil cockpit


30


is supported. A tunnel


31


extends through interior cavity


23


and communicates with the interior of cockpit


30


. Push-button


16


is shown in its relaxed position at the rear of hull


11


which as is described below in greater detail allows toy airship


10


to assume the alternate configuration of FIG.


2


.




Panels


20


and


21


are supported in the extended position of

FIG. 2

by a cortex of pivotally supported arms


40


,


41


,


42


and


43


. Arm


40


extends inwardly through a slot


32


formed in cockpit


30


while arm


41


extends inwardly through a slot


33


also formed in cockpit


30


. While not seen in

FIG. 2

, it will be understood that cockpit


30


defines a similar pair of slots


32


and


33


(shown in

FIG. 3

) through which arms


42


and


43


extend.




Arm


40


defines a socket


70


at its outer end while arm


41


defines a socket


71


at its outer end. Correspondingly, panel


20


defines a pair of posts


50


and


51


which in turn support a pair of balls


60


and


61


. The cooperation of ball


60


within socket


70


and ball


61


within socket


71


provide a freely pivotable attachment between panel


20


and the outer ends of arms


40


and


41


. As is set forth below in

FIGS. 4 and 5

, the operation of the ball and socket attachments thus formed allows panel


20


to articulate and move to the closed configuration of

FIG. 1

when arms


40


and


41


are drawn into interior cavity


23


.




Similarly, arms


42


and


43


define respective sockets


72


and


73


while panel


21


defines a pair of posts


52


and


53


supporting respective balls


62


and


63


. In similarity to panel


20


, the cooperation of ball


62


within socket


72


and ball


63


within socket


73


provides a freely articulated attachment for panel


21


to the outer ends of arms


42


and


43


. This freely articulated attachment allows panel


21


to pivot and move in a closure movement as arms


42


and


43


are pivoted into interior cavity


23


which in turn allows panel


21


to be moved to the closed configuration of FIG.


1


.




Cockpit


30


allows defines stop edges


36


and


37


in slots


32


and


33


respectively, as well as corresponding stop edges


38


and


39


in slots


34


and


35


(seen in FIG.


3


). As is described below in greater detail, the configuration of toy airship


10


from the hydrofoil configuration shown in

FIG. 2

to the closed airship shown in

FIG. 1

is attained in part by the cooperation of arms


40


through


43


against stops


36


through


39


. This cooperation is carried forward in the manner set forth below in

FIGS. 3 through 5

. However, suffice it to note here, that as the user presses button


16


inwardly and forwardly within hull


11


, the operative mechanism set forth below carries the interior ends


40


through


43


forwardly against stops


36


through


39


respectively. This cooperation in turn causes arms


40


through


43


to pivot rearwardly and inwardly drawing panels


20


and


21


into the closed configuration of

FIG. 1

in the manner particularly illustrated in

FIGS. 4 and 5

. Conversely, each time the user releases button


16


the operative mechanism set forth below again allows arms


40


through


43


to pivot outwardly and thereby support panels


20


and


21


in the extended hydrofoil craft configuration of FIG.


2


. Thus, the entire configuration and reconfiguration of toy airship


10


is carried forward by simply pressing button


16


inwardly and holding it within hull


11


or alternatively releasing it. This greatly simplifies the configuration of toy


10


between its alternate configurations.





FIG. 3

sets forth a partially sectioned top view of toy airship


10


in the hydrofoil configuration shown in FIG.


2


. As described above, toy airship


10


includes an elongated hull


11


supporting a vertical tail fin


14


and horizontal tail fins


15


and


19


. Hull


11


further defines edges


12


,


17


and


18


. A cockpit


30


is supported within hull


11


and an elongated hollow tunnel


31


extends to cockpit


30


. Cockpit


30


defines elongated slots


32


,


33


,


34


and


35


. The forward edges of slots


32


through


35


define respective stop edges


36


through


39


. Hull


11


further defines an elongated channel


80


within which a pair of guide surfaces


81


and


82


are supported. A slide


84


is received within channel


80


and movable upon guide surfaces


81


and


82


in a front-to-back motion as indicated by arrows


125


and


126


. Slide


84


includes a pair of outwardly extending front flanges


90


and


92


and a pair of outwardly extending rear flanges


91


and


93


. Slide


84


further defines an elongated slot


85


which receives the upper end of a guide post


86


(seen in FIG.


4


). Post


86


captivates slide


84


within channel


80


by the attachment of an annular guide


94


to the upper end of post


86


using a conventional fastener


95


.




A coil spring


109


is supported within hull


11


and exerts a spring force against slide


984


urging in rearwardly in the direction indicated by arrow


126


configuring toy airship


10


in the position shown in solid line representation in FIG.


3


.




Arm


40


is pivotally secured to flange


92


by a fastener


107


and a washer


102


. Similarly, arm


42


is pivotally secured to flange


90


by a fastener


105


and a washer


100


. Arms


41


and


43


are similarly secured to flanges


93


and


91


respectively in a pivotal attachment using fasteners


108


and


106


. Button


15


is joined to an inwardly extending shaft


83


which passes through tunnel


31


and which is joined to the rear portion of slide


84


. Thus, forces exerted by the user against button


16


are imparted to slide


84


. Correspondingly, forces exerted against slide


84


by spring


109


are imparted to button


16


by shaft


83


.




In the open configuration shown in solid line representation in

FIG. 3

, toy airship


10


has assumed a hydrofoil craft configuration as a result of the absence of an inward force upon button


16


by the user. In the absence of any force against button


16


, the force of spring


109


in the direction indicated by arrow


126


against slide


84


moves slide


84


rearwardly. The rearward movement of slide


84


in the direction of arrow


126


correspondingly moves the interior pivotally attached ends of arms


40


through


43


. A pair of stops


110


and


111


are supported upon guide surfaces


82


and


81


respectively within channel


80


and within the travel path of arms


40


and


42


as slide


84


moves rearwardly. Thus, as spring


109


continues to force slide


84


in the direction indicated by arrow


126


, the cooperation of stops


111


and


110


against arms


40


and


42


produces a force upon arms


40


and


42


which pivots them in the directions indicated by arrows


128


and


127


. The joint coupling at the outer end of arms


40


and


41


provided by balls


60


and


61


and sockets


70


and


71


communicates the forward pivotally movement of arm


40


to arm


41


causing arm


41


to also pivot in the direction indicated by arrow


130


. Similarly, the attachment provided by balls


62


and


63


and sockets


72


and


73


of arms


42


and


43


communicates the pivotal movement of arm


42


to arm


43


causing arm


43


to be pivoted in the direction indicated by arrow


129


. As a result, toy airship


10


assumes and maintains the open configuration shown in solid line representation in FIG.


3


.




In accordance with the present invention, toy airship


10


is capable of being reconfigured to the airship configuration illustrated in

FIG. 1

by the user simply forcing button


16


inwardly in the direction indicated by arrow


120


. As the user presses button


16


forwardly in the direction indicated by arrow


120


the force against button


16


is communicated by shaft


83


to slide


84


. As the user overcomes the force of spring


109


, slide


84


is forced forwardly in the direction indicated by arrow


125


. The forward movement of slide


84


carries arms


40


through


43


against stops


36


through


39


respectively. As the user continues to force button


16


forwardly and continues to drive slide


84


in the direction indicated by arrow


125


, the cooperation of stops


36


through


39


and the pivotal attachment of arms


40


through


43


causes arms


40


through


43


to pivot inwardly. Thus, as slide


84


moves forward, arm


40


is pivoted in the direction indicated by arrow


122


while arm


42


is pivoted in the direction indicated by arrow


121


. Correspondingly, arm


41


is pivoted in the direction indicated by arrow


124


while arm


43


is pivoted in the direction indicated by arrow


123


. The rearward and inward pivotal movement of arms


40


through


43


draws panels


20


and


21


inwardly against hull


11


through the dashed line configuration shown in FIG.


3


. As the forward movement of slide


84


continues the pivotal movement of arms


40


through


43


draws panels


20


and


21


into the closed configuration shown in FIG.


1


.

.




More specifically, toy airship


10


includes a hull


11


supporting a post


86


. Hull


11


further defines edges


12


and


18


together with an interior cavity


23


. Toy airship


10


further includes a cockpit


30


having stops


36


and


38


formed therein. Hull


11


further includes a channel


80


having guide surfaces


81


and


82


formed therein. A slide


84


is movably supported within channel


80


upon surfaces


81


and


82


. Slide


84


further defines a slot


85


through which the upper end of post


86


extends. A guide washer


94


and fastener


95


are secured to the upper end of post


86


captivating slide


84


within channel


80


. Channel


80


further supports a pair of stop members


110


and


111


each supported upon respective surfaces


82


and


81


.




Toy


10


further includes a pair of arms


40


and


42


pivotally secured to slide


84


by respective fasteners


107


and


105


together with respective washers


102


and


100


. The outer end of arm


40


defines a socket


70


which receives a ball


60


. Ball


60


is secured to panel


20


by a post


50


. Similarly, the outer end of arm


42


defines a socket


72


which receives a ball


62


. Ball


62


is supported upon panel


21


by a post


52


.




In the configuration shown in

FIG. 4

, toy airship


10


is undergoing the above described transformation from the open configuration of

FIG. 2

to the closed configuration of FIG.


1


. As described above, the forward movement of slide


84


forces arms


40


and


42


against stops


111


and


110


respectively. The cooperation of stops


111


and


110


with arms


40


and


42


causes arms


40


and


42


to be pivoted inwardly as indicated by arrows


141


and


140


. As is also described above, a corresponding inward pivotal motion is imparted to arms


41


and


43


due to the coupling of arms


40


and


42


to panels


20


and


21


. Thus, while not seen in

FIG. 4

, it will be understood that a similar rearward and inward pivotal movement is occurring in arms


41


and


43


as slide


84


is forced forwardly.




At the point illustrated in

FIG. 4

, the pivotal movements of arms


40


through


43


draws the interior edges of panels


20


and


21


against hull


11


. The continued pivotal rearward and inward movement of arms


40


through


43


together with the ball and socket attachments between panels


20


and


21


and arms


40


through


43


pivots panels


20


and


21


upwardly and inwardly as indicated by arrows


142


and


143


. This pivotal movement continues until panels


20


and


21


have been drawn inwardly to close in the manner shown in FIG.


5


.
