Abstract
A toy figure having an arm or leg incorporates an internal clicking sound-generating mechanism. For toy figures molded from deformable plastic material, the sound-generating mechanism is within an arm or leg of the toy, and includes first and second members relatively movably engageable with each other inside a closed chamber. A clicking sound is produced thereby, typically when the arm or leg is bent. The arm or leg is formed by an insert molding operation with the plastic material molded to shape completely around the sound-generating mechanism. For other toy figures, such as stuffed animals, the filling or stuffing surrounds the sound-generating mechanism, and the portions of the sound-generating mechanism that engage each other are arranged inside a closed chamber, or at least within an enclosure shaped to substantially exclude the filling or stuffing.
Description




FIELD OF THE INVENTION




The present invention relates to a toy figure which incorporates a clicking sound-generating mechanism.




BACKGROUND OF THE INVENTION




Clicking sound-generating mechanisms for toys are generally known. For example, as disclosed in UK Patent Application No. 8431602 published under Publication No. 2151495, one form of a clicking sound-generating mechanism is provided by a resilient finger-like member and a cog wheel which is, upon rotation, momentarily engageable with the finger-like member to produce a clicking sound. Certain other clicking sound-generating mechanisms are disclosed in UK Patent No. 1373205 ad UK Patent Application No. 8138187 published under Publication No. 2091570.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, there is provided a toy figure having a body part which is molded of deformable plastic material, said body part having incorporated therein a sound generator or sound-generating mechanism which comprises first and second members relatively movably engageable with each other for producing a clicking or tapping sound upon relative movement thereof, at least the respective portions of said members which are engageable with each other for producing said sound being arranged inside a closed chamber which is substantially impermeable or impervious to the plastic material during molding.




In one embodiment of the invention, the body part is formed by an insert molding operation with the plastic material molded to shape completely around at least the closed chamber. Conveniently, the members may form the skeleton of the body part and the relative movement of the members may deform and determine the shape or configuration of the body part. In practice, the body part would be bent.




In accordance with another aspect of the present invention, there is provided a toy figure having a part which is molded from deformable plastic material, said part incorporating an internal clicking sound-generating mechanism which has a closed chamber and includes first and second members relatively movably engageable with each other inside said chamber for producing a clicking sound upon relative movement when said part of the toy figure is bent, said part being formed by an insert molding operation with the plastic material molded to shape completely around said sound generator.




Preferably, the chamber is provided by the first member which has a portion inside the chamber for engaging a portion of the second member.




More preferably, the chamber has an opening at which the portion of the second member is positioned closing said opening of the chamber as a sliding fit.




In a preferred embodiment, the members have respective portions and the chamber has an opening to which the portion of the second member is pivotably connected for movably engaging the portion of the first member inside the chamber to produce a clicking sound.




Further more preferably, the portions of the first and second members have a pointed end and a series of teeth, respectively.




Conveniently, the chamber may be formed by two separate parts which are sealed together.




It is preferred that the members are elongate and have adjacent ends connected together for relative pivotal movement.




Preferably, the toy figure has a shape resembling a human being. More preferably, the part is in the form of a limb.




In practice, the toy figure would have a dimension between 5 and 6 inches. In most cases, the toy figure would be less than 12 inches.




The sound-generating mechanism may also be incorporated into toys other than those made of deformable plastic. For example, the mechanism may be used with stuffed animals, including dolls, monsters, etc. The body part in these toys may be formed by a deformable outer shell with filling or stuffing material surrounding or around the sound-generating mechanism. The outer shell may be made of any suitable flexible material such as cloth or leather, and the filling or stuffing may be a fibrous material such as polyester, cotton, or wool, or may be foam beads, beans, or other suitable material. With these types of “stuffed” toys, it is sufficient that the portions of the sound-generating mechanism that engage each other are arranged within an enclosure shaped to exclude the filling or stuffing.




With stuffed toys, the sound-generating mechanism is preferably embodied in a universal ball and socket joint configuration, wherein the ball is secured in a first housing, and the socket is defined by the cooperating end of a second housing which has a hammering pin therein. The ball has a plurality of dimples or indentations, and when the joint is operated the hammering pin engages and disengages various dimples to create the clicking or tapping sound.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




Referring to the drawings, there is shown a toy figure, for example in the shape of a human wrestler


10


between


5


and


6


inches in dimension, embodying the invention, which wrestler


10


has a head


11


and a body


12


, and two arms


13


and two legs


14


. Each arm


13


or leg


14


incorporates an internal sound-generating mechanism


20


which is adapted to produce a clicking sound when the arm


13


or leg


14


is bent at the elbow or knee position. The arms


13


and legs


14


may be molded from PVC plastic material to be slightly flexible or deformable in a resilient manner, or they may be formed of any suitable flexible material such as cloth, with stuffing material contained therein to provide a desired shape. In a first embodiment, the sound-generating mechanism


20


is formed by first and second bars


21


and


22


which are hinged end-to-end together for limited pivotal movement relative to each other to produce the clicking sound.




The first bar


21


is formed by elongate base


23


and lid


24


. The base


23


has an integral series of two side walls


25


and an end wall


26


together defining a chamber


27


. The chamber


27


is flat and oblong and has an open principal side


28


and an open end


29


opposite to the end wall


26


. The end wall


26


and the open end


29


are provided with respective upstanding central posts


26


A and


29


A. The lid


24


, which has opposite end holes


30


, closes the open side


28


of the chamber


27


and is located in position by means of its end holes


30


engaging the respective posts


26


A and


29


A. Ultrasonic welding, heat sealing or glue may be used to secure the lid


24


against the walls


25


and


26


, whereby the chamber


27


is fully closed or sealed except at the open end


29


on opposite sides of the post


29


A.




Inside the chamber


27


, an integral central post


31


is formed on the base


23


close to the end wall


26


and a resilient thin wedge-like blade


32


is held captive. The blade


32


has a broad rear end


33


and a pointed front end


34


, said rear end


33


bearing a central hole


35


. The rear end


33


has a shape almost the same as that of the end of the chamber


27


closed by the end wall


26


and is fitted in position with the hole


35


engaging the post


31


. The front end


34


points, at a small distance off, at the post


29


A at the open end


29


of the chamber


27


. The base


23


includes, at an end opposite to the chamber open end


29


, an inclined integral ring


36


, and further includes integral spikes


37


on opposite sides between the chamber


27


and the ring


36


and an integral collar


38


under the chamber


27


.




The second bar


22


has a rounded first end


39


which is provided with a central hole


40


to form half a ring. The round end


39


is serrated, on its outermost side, to form a series of triangular teeth


41


. Opposite end


42


of the second bar


22


is thinner than the round end


39


. The body of the second bar


22


is formed with two openings


43


and an integral collar


44


.




To assemble the two bars


21


and


22


together, while they are extending co-parallel, the round end


39


of the second bar


22


is disposed around the post


29


A of the first bar


21


. The open end


29


of the chamber


27


is thus closed by the round end


39


. The lid


24


is then positioned to close and seal the open side


28


of the chamber


27


, as described above. In this assembled condition, the blade end


34


of the first bar


21


and the end teeth


41


of the second bar


22


come into inter-engagement inside the chamber


27


. Also, the second bar


22


is pivotable, to a limited extent, typical between 180° and 45° about the post


29


A relative to the first bar


21


.




The open end


29


of the chamber


27


has partially circular opposite sides


29


B and


29


C to form an angular sliding fit with the respective partially circular sides of the round end


39


on opposite sides of the teeth


41


. Such a sliding fit ensures that the chamber


27


is also closed at its open end


29


, whereby the chamber


27


is fully closed. One side


29


B of the open end


29


is extended to restrict the pivotal movement of the second bar


22


only to the opposite side.




Upon back and forth pivotal movement of the second bar


22


relative to the first bar


21


, the teeth


41


of the round end


39


of the second bar


22


will in turn momentarily engage with and disengage from the pointed end


34


of the blade


32


of the first bar


21


, thereby producing a clicking sound. Conversely, the first bar


21


may be pivoted back and forth relative to the second bar


22


, with the blade end


34


of the first bar


21


clicking through the end teeth


41


of the second bar


22


to produce the same sound.




Each arm


13


or leg


14


in this first embodiment is formed by an insert molding operation, in which the assembled sound-generating mechanism


20


is initially placed inside an appropriate mold and molten PVC plastic material is then injected into the mold to surround and enclose the soundgenerating mechanism


20


completely. As the chamber


27


is fully closed or sealed and made impermeable or impervious to the plastic material, the molding material cannot leak into the chamber


27


to clog or otherwise interfere with the workings of the blade


32


and the second bar end


39


including the teeth


41


. The sound-generating mechanism


20


is arranged to extend across the elbow or knee, with the first bar


21


along the upper arm or thigh and the second bar


22


along the forearm or lower leg, such that when the limb


13


or


14


is bent about the elbow or knee, the sound-generating mechanism


20


will produce a clicking sound.




The ring


36


of the first bar


21


is exposed at the root end of the arm


13


or leg


14


and provides a rigid opening for hinging the limb


13


or


14


to the body


12


of the wrestler


10


. The spikes


37


, collars


38


and


44


and openings


43


on the bars


21


and


22


serve as additional formations for anchoring with the set or cured plastic material, thereby avoiding displacement of the sound-generating mechanism


20


.




The insert molding operation is commonly used to manufacture toy figures having a dimension less than 12 inches. The molded plastic material used is deformable and has the suitable thickness and flexibility or hardness to allow the arm


13


or leg


14


to be bent into different positions and be able to hold those positions.




In an alternative embodiment, the sound generating mechanism


20


is used with a stuffed toy. In this embodiment, the body part may be formed by a deformable outer shell with filling or stuffing material (not shown) surrounding or around the sound-generating mechanism


20


. The outer shell may be made of any suitable flexible material such as cloth or leather, and the filling or stuffing may be polyester, cotton, wool, foam, pellets, or other material suitable for defining a shape of the outer shell. With these types of “stuffed” toys, it is sufficient that the portions of the sound-generating mechanism


20


that engage each other are arranged within an enclosure or chamber


50


shaped to exclude the filling or stuffing. The enclosure


50


does not have to be completely closed.




With stuffed toys, the sound-generating mechanism


20


described in conjunction with the plastic body part may be used. Alternatively, the sound generating mechanism


20


may be embodied in a universal ball and socket joint configuration as seen in

FIGS. 5-8

. This type of joint provides for a wider range of movement, including different angles, as indicated by arrows


51


in

FIGS. 6 and 7

.




The ball portion


52


is connected to a stem


54


that is secured in a first housing


56


, and the socket


57


is defined by the cooperating end of a second housing


58


which has a hammering pin


60


therein. The ball


52


has a plurality of dimples or indentations


62


thereon, similar to a golf ball, and when the joint is operated the hammering pin


60


engages and disengages various dimples


62


to create the clicking or tapping sound. The size, number, and orientation of the dimples


62


may vary, without departing from the scope of this embodiment of the present invention.




The hammering pin


60


is forced against the indented surface of the ball


52


by a spring element


64


, held in place by a washer


66


. The tip of the hammering pin


60


may be tapered, and is preferably configured to rest comfortably within an indentation


62


when the joint is not moving. The second housing


58


may comprise apertures for sound dissipation, but the size and/or shape of the apertures must be such that the filling material is excluded from the enclosure


50


where the ball


52


and hammering pin


60


contact each other. It is also preferable that the filling material be excluded from the inside of the second housing


58


, at least in the areas where movement of the hammering pin


60


occurs. This would help lessen the likelihood that any filling material might obstruct or otherwise interfere with operation of the hammering pin


60


.




When the ball and socket joint is operated, thereby moving the ball


52


and the socket


57


relative to each other, a clicking or tapping sound is generated by the tip of the hammering pin


60


moving from one indentation


62


to another. The relative movement may also cause the hammering pin


60


to vibrate and produce a louder and longer lasting sound.




It is preferred that more than half of the ball portion


52


is received in the socket


57


, and that the socket opening is smaller than the circumference of the ball portion


52


, so that the ball portion


52


stays operatively secured within the socket


57


without the use of any additional attachments.




Turning briefly to

FIGS. 9A-9B

, an alternative embodiment of the ball portion


52


is shown in which the ball portion


52


does not comprise a continuous substantially spherical surface. Rather, only the part of the ball portion


52


that includes dimples


62


has a continuous substantially spherical surface, but the remainder of the ball portion


52


is in the form of a spherical skeleton or structural frame


63


. In this embodiment, less material is needed to manufacture the ball portion


52


. Such a configuration operates effectively, because as seen in

FIG. 9B

, the spherical skeleton


63


is not contacted by the hammering pin


60


, but serves primarily to allow the second housing


58


to maintain its desired range of movement as part of the ball and socket joint.




The first housing


56


may be angular as seen in

FIGS. 6A-6C

, or straight as seen in

FIGS. 7A-7C

, and generally will form the skeleton of the upper portion of a limb (see FIG.


5


). As seen in

FIG. 5

, the angular version is preferred where the body part containing the sound generator


20


is an arm, and the straight version is preferred where the body part is a leg. The upper end


68


of the angular version of the first housing


56


is preferably fixed to the torso of the toy doll at the shoulder position, while the lower end


70


of the second housing


58


is fixed to the hand of the toy doll. Thus, the first housing


56


forms the skeleton of the upper arm (shoulder to elbow), while the second housing


58


forms the skeleton of the lower arm or forearm (elbow to hand). Similarly, for the straight version of the first housing


56


, one end may be fixed to the lower part of the torso at the hip position, while the other end is fixed to a foot. Thus, in one orientation, the upper end


72


of the straight version of the first housing


56


is fixed to the lower part of the torso at the hip position, and the first housing forms the skeleton for the upper leg (hip to knee), while the lower end


70


of the second housing is fixed to a foot of the toy figure, and the second housing forms the skeleton of the lower leg (knee to foot). In the opposite orientation, the first housing


56


is fixed to a foot while the second housing


58


is fixed to the torso. Ribs or ridges


73


(see

FIGS. 9A-9B

) may be provided at the lower end


70


of the second housing


58


to provide a mechanism for attaching a hand (with respect to the angular version of the second housing


58


) or foot (with respect to the straight version of the second housing


58


) of the toy

FIG. 10

thereto. The ribs or ridges


73


may be tapered on one side, as seen at


75


.




Preferably, the hands, feet, gloves, boots, etc., as well as the head of the toy figure, are made of deformable plastic and are hollow inside, while the arms, legs, and torso of the toy figure are formed of a flexible outer shell such as cloth, leather, or PVC. However, the hands, feet, gloves, boots, etc., as well as the head, may also be made of a flexible outer shell and filled with stuffing material as the rest of the toy figure. The limbs are stuffed with soft filling material around the sound generating mechanism


20


.




The invention has been given by way of example only, and various other modifications of and/or alterations to the described embodiment may be made by persons skilled in the art without departing from the scope of the invention as specified in the appended claims. For example, it is envisaged that the sound-generating mechanism


20


may be provided across the neck or waist of the wrestler


10


, for producing a clicking or tapping sound when the neck or waist is bent.
