Description




BACKGROUND OF THE INVENTION




This invention relates to a toy moving device, and in particular, to a convertible walking and riding device and a method of using the device.




There are many types of conventional toy walking or riding devices. Conventional toy walking devices are usually designed for a single mode of use, such as to provide support for a child that is walking. Such walking devices typically do not include a seat or support area on which a child may sit.




Conventional toy riding devices are also usually designed for a single mode of use. Such riding devices usually include a handle and a seat-like structure located behind the handle. The seat-like structure is usually located behind the handle such that a child cannot simultaneously hold on to the handle and walk.




Some toy riding devices include moveable parts that enable the device to be used in different configurations. For example, a child may use a riding device in a standing position (such as on a scooter) or in a seated position (such as on a tricycle). However, many of these toy riding devices are usually difficult to convert between different configurations. Moreover, the moveable parts of these devices do not move sufficiently to provide a walking area to enable a small child to use the riding device in a stable walking mode.




A need exists for a toy walking and riding device that is easily convertible from a stable walking configuration to a riding configuration.




SUMMARY OF THE INVENTION




A convertible toy walking and riding device includes a front portion and a seat portion coupled to the front portion. The seat portion is moveable relative to the front portion between several positions. In one position, the seat portion and the front portion form a walking configuration. In another position, the seat portion and the front portion form a riding configuration. In one embodiment, the seat portion is pivotally coupled to the front portion. In another embodiment, the seat portion is slidably coupled to the front portion.




In one embodiment, the seat portion is a single member. In an alternative embodiment, the seat portion includes two seat members that are moveable relative to each other and relative to the front portion.




The front portion is supported on one or more wheels for movement on a support surface. Similarly, the seat portion is supported on one or more wheels. In one embodiment, the walking and riding device has an entertainment portion that includes an output generating system and several play components, such as balls mounted on a track. The output generating system can be user activated and/or motion activated.

194


on lower housing


180


, about which seat portions


260


and


310


are rotatably mounted.




Referring to

FIG. 39

, some of the relative positions of the seat portions


260


and


310


are illustrated. Seat portion


260


is movable between a first position


300


corresponding to the riding configuration


102


of the device


100


and a second position


302


(illustrated in phantom) corresponding to the walking or walker configuration


104


of the device


100


. Similarly, seat portion


310


is movable between a first position


350


corresponding to the riding configuration


102


of the device


100


and a second position


352


(as illustrated in phantom) corresponding to the walking configuration


104


of the device


100


.




When the seat portions


260


and


310


are in their first positions


300


and


302


, they are disposed in the walking area


130


. When the seat portions


260


and


310


are in their second positions


350


and


352


, they are spaced laterally from the walking area


130


.




In the illustrated embodiment, when one of the seat portions


260


,


310


is rotated, the other seat portion simultaneously rotates in the opposite direction around the pivot point


256


. Each of the seat portions


260


,


310


rotates the same distance about the pivot point


256


.




As discussed above, coupling plate


290


of seat portion


260


includes three arcuate slots


294


,


295


, and


296


. Coupling plate

157


extend through slots


295


and


345


. Extensions


197


C and post


158


extend through slots


294


and


344


. Because the extensions and post are positioned within these slots, the range of rotation of the seat portions


260


and


310


is limited by length of these slots.




The angle that the seat portions


260


and


310


can rotate is represented by the angle “M” illustrated in FIG.


39


. The angle “M” is determined by the length of the slots and can be varied depending on the desired width of the walking area


130


between the seat portions


260


and


310


. In the illustrated embodiment, angle “M” is approximately 35°.

350


, the recess


348


on coupling plate


340


is aligned with slot


154


and is in its first position


304


illustrated in FIG.


39


. When the seat portion


310


is moved to its walking position


352


, the recess


348

into engagement with the recess


348


. When the upper end


562


of the button


560


engages the recess


348


, the seat portions


260


and


310


are retained in their walking positions


302


and


352


, respectively. The button


560


functions as a latch or lock to retain the device


100


in its walker or walking configuration

.




When a user presses downwardly on the upper end


562


of the button


560


, the button


560


disengages from recess


348


and the seat portions


260


and


310


can be moved toward each other.




The convertible walking and riding device


100


is illustrated in its walking configuration


104


in FIG.


40


. In this configuration


104


, the device


100


has a walking area or region


130


formed between the seat portions


260


and


310


. As illustrated, the coupling plates


290


and


340


of the seat portions


260


and


310


, respectively, are mounted between the plate


148


and the mount


192


.




Seat portion


260


is rotated about pivot point


256


along the direction of arrow “O” to its walking position


302


. Similarly, seat portion


310


is rotated about pivot point


256


along the direction of arrow “P” to its walking position


352


. While the seat portions


260


and


310


are moved relative to the front portion


110


, the rear wheels


370


and


372


rotate relative to seat portion


260


and rear wheels


374


and


376


rotate relative to seat portion


310


. This rotation of the rear wheels is discussed in greater detail with respect to

FIGS. 41 and 42

.




Referring to

FIG. 40

, a line


362


extends along the longitudinal axis of seat portion


260


and a line


360


is aligned along the direction of travel of rear wheels


370


and


372


. Together, lines


360


and


362


define an angle “N” therebetween. The angle “N” corresponds to and is the same as angle “M” (see

FIG. 39

) and represents the amount of angular movement or rotational movement of the seat portions


260


and


310


relative to the front housing


110


. In other words, as seat portions


260


and


310


move along the directions of arrows “O” and “P,” respectively, the rear wheels


370


and


372


rotate so as to maintain their alignment with the direction of movement of the device


100


along the direction of arrow “L.”




Links


500


and


550


are movably mounted beneath seat portions


260


and


310


. As illustrated in

FIG. 40

, links


500


and


550


extend from the inner walls of the seat portions


260


and


310


when the seat portions


260


and


310


are spaced apart. When the seat portions


260


and


310


are moved together, the links


500


and


550


engage each other and simultaneously push each other into their retracted positions beneath the seat portions


260


and


310


.




Some components of the convertible device


100


are illustrated in

FIGS. 41 and 42

. In these figures, seat portion


260


is not illustrated, thereby allowing the internal components in axle holder


440


to be illustrated.




As discussed above, the upper end


382


of the wheel mount


380


is coupled to an axle mount


520


that is pivotally mounted within axle holder


440


. Also, link


500


is coupled to the axle mount


520


.




The components in

FIG. 41

are illustrated in their respective positions corresponding to the riding configuration


102


of the device


100


. In this configuration


102


, the links


500


and


550


are engaging each other. When the links


500


and


550


engage each other, each link is forced to its retracted position beneath the corresponding seat portion


260


and


310


. Link


500


is illustrated in its retracted position


512


in FIG.


41


.




Link


500


is mounted on post


526


of axle mount


520


. Axle mount


520


is biased by a spring (not shown) for rotation about pivot point


534


along the direction of arrow “S.” The spring can engage tab


530


or extension


528


on the axle mount


520


to provide the biasing force.




When link


500


is pushed inwardly along the direction of arrow “Q,” axle mount


520


rotates about pivot point


534


along the direction of arrow “R.” The rotation of axle mount


520


causes wheel mount


380


to rotate about pivot point


534


in the same direction. When axle mount


520


rotates, rear wheels


370


and


372


and axis of rotation


378


also rotate about pivot point


534


with respect to seat portion


260


and are aligned with the longitudinal axis of the seat portion


260


.




The components in

FIG. 42

are illustrated in their respective positions corresponding to the walking configuration


104


of the device


100


. In the walking configuration


104


, the links


500


and


550


are not in engagement with each other. In this configuration, the axle mount


520


is biased for rotation about pivot point


534


along the direction of arrow “S.”




When axle mount


520


rotates along the direction of arrow “S,” link


500


moves along the direction of arrow “T” to its extended position


514


. The rotation of axle mount


520


causes wheel mount


380


to rotate about the pivot point


534


in the same direction. Rear wheels


370


and


372


also rotate about pivot point


534


and are aligned with the direction of travel of the device


100


which corresponds to line


360


. This structure and operation of the rear wheels ensures that the rear wheels automatically rotate to be aligned with the front wheels and with the direction of travel of the device


100


in any configuration of the device


100


.




While the mounting and movement of rear wheels


370


and


372


and their associated components are discussed above relative to

FIGS. 41 and 42

, the mounting and movement of rear wheels


374


and


376


is a reverse-image of rear wheels


370


and


372


. Accordingly, only rear wheels


370


and


372


are discussed in detail for simplicity reasons only.




The operation of the locking mechanism of the convertible device


100


is discussed relative to

FIGS. 43 and 44

, which are bottom perspective views of the seat of the device


100


. The seat portions


260


and


310


are illustrated in their riding positions in these figures. Rear wheels


374


and


376


are not illustrated for purposes of simplicity.




Referring to

FIG. 43

, lock


480


is coupled to the lower surface of axle holder


440


. The lock


480


is selectively moveable between an unlocked position


494


(see

FIG. 43

) and a locked position


496


(see FIG.


44


). When the lock


480


is in its unlocked position


494


, the lock


480


is located completely beneath the seat portion


260


.




As discussed with respect to

FIGS. 23 and 25

, spring


470


engages shaft


492


and biases lock


480


for rotation about pivot point


498


along the direction of arrow “U.” The lock


480


can be manually rotated about pivot point


498


to its locked position


496


along the direction of arrow “V.”




When the locking portion


484


of the lock


480


is inserted into passageway


424


on axle holder


400


, the lock


480


is retained in its locked position


496


due to the structure of the lock


480


and the friction between the passageway walls and the locking portion


484


. The engagement of lock


480


with passageway


424


prevents the seat portions


260


and


310


from separating when the device


100


is in its riding configuration


102


. The lock


480


holds seat portions


260


and


310


together under the spring loads associated with the axle mounts


520


and


540


. A user can press on a portion of the lock


480


adjacent to slot


486


to disengage the locking portion


484


of the lock


480


from the passageway


424


.




While the components of the convertible device


100


are made of molded plastic, any suitable material that can support the weight of a child may be used.




In alternative embodiments, the particular configuration and shape of the link may vary.




In an alternative embodiment, the seat portions


260


and


310


can be mounted to the front portion


110


for laterally translating movement relative to the front portion


110


instead of rotational movement.




In an alternative embodiment, each seat portion


260


and


310


can be supported by a single rear wheel.




In alternative embodiments, the latch or lock may be placed on either seat portion to retain the seat portions in their positions proximate to each other. Alternatively, the latch or lock may be located on the front portion or chassis of the device. In this arrangement, the latch or lock may engage a passageway that is formed on one or both of the seat portions.




In an alternative embodiment, the device


100


may include only one of the seat portions


260


and


310


.




Alternatively, any number of balls may be mounted on the handle or loosely associated with the front portion of the device.




While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope thereof. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
