Description

FIELD OF THE INVENTION

The present invention relates generally to the field of motion induced sound and light generating devices. More particularly, the invention relates to a riding toy configured to generate sounds and lights in response to the motion of the toy.

BACKGROUND OF THE INVENTION

Children enjoy playing on riding toys, particularly toys that move in a generally cyclical motion. Children also enjoy playing with toys shaped as vehicles, animals, dinosaurs and other conventional shapes. Boys and girls alike often participate in role playing in which the child pretends to be a policeman, fireman, cowboy, cowgirl or other adult role. When playing such roles, children often simulate role related noises. For example, for a policeman role, police related sounds are often generated, such as a siren, communications with a central dispatcher and police vehicle noises. Additionally, children are especially attracted to interactive toys which produce sounds or lights in response to the child's input.

Riding toys are well known. Riding toys which produce sounds when the child depresses a pushbutton or when air is moved through the toy are also generally known. Riding toys typically resemble animals, dinosaurs or vehicles. Other toys, such as impact balls or small musical toys, which produce a sound when impacted are also known.

Existing riding toys, however, have a number of drawbacks. Such riding toys typically require the child to remove one or both hands from the handles of the riding toy in order to initiate sounds. Existing riding toys also provide only minimal interactive play options for the child. Riding toys typically produce no sound or lights in response to the child's riding of the toy. Those toys which do produce a sound when the toy is moved typically do not provide variations in the sound output of the toy based upon the child's movement of the toy.

Thus, there is a need for an improved riding toy which produces sound or light in response to the child's operation of the toy. It would also be advantageous to provide a riding toy that produces varying signals based upon the motion imparted by the child to the riding toy. What is needed is riding toy which interacts with the child's actions and is safe, fun and easy for children to use.

In a preferred embodiment, the control unit 14 is configured for removably mounting onto more than one toy body 12 enabling the user to transfer the control unit 14 to another toy body having an alternative shape, thereby increasing the overall versatility of the control unit 14 and the riding toy 10 . The control unit 14 can be produced, transported, marketed, replaced and stored separately from the toy body 12 . The compact size of the control unit 14 relative to the size of the toy body 12 enables control unit 14 to be easily removed, stored and replaced enabling a user to, for example, store the toy body 12 outdoors and the control unit 14 indoors.

Referring to FIG. 3 , the control unit 14 includes a set of handles 26 , at least one pushbutton, at least one light, a switch 30 , a front shield 32 and openings 27 for a sound transducer 28 (shown on FIG. 5 ). The handles 26 are elongate extensions extending from the housing of the control unit 14 . In a preferred embodiment, the handles 26 are formed from extensions of the front and rear housing sections 22 , 24 . The handles 26 are configured to provide a location for grasping of the riding toy 10 by the child.

In a preferred embodiment, the control unit 14 includes six pushbuttons: a siren button 34 , a horn button 36 , an engine simulation button 38 , and first, second and third voice activation buttons 40 , 42 , 44 , respectively. The pushbuttons 34 , 36 , 38 , 40 , 42 , 44 are conventional electronic pushbuttons coupled to the rear housing section 24 of the control unit 14 . As shown in FIG. 5 , each pushbutton 34 , 36 , 38 , 40 , 42 , 44 is electrically coupled to a printed control board 56 (“PCB”) Referring to FIG. 3 , a portion of each of the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 extends through an opening within the rear housing section 24 . Each of the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 is a switch, which when depressed by a child, sends a voltage signal to a PCB 56 (“PCB”) (shown on FIG. 5 ) resulting in a sound or a series of sounds being generated from the sound transducer 28 . The siren button 34 , when depressed, is configured to produce sounds simulating a siren. Similarly, the horn button 36 produces horn sounds, the engine simulation button 38 produces engine revving sounds, and the first, second, and third pushbuttons 40 , 42 , 44 produces human voice sounds, for example, “calling officer, report to headquarters”, “we have an emergency, please investigate,” and “mission accomplished, good job,” respectively.

The switch 30 is shaped to resemble an ignition switch with a key placed in it. A portion of the switch 30 extends through an opening in the rear housing section 24 of the control unit 14 . The switch 30 is connected to the rear housing section 24 . When actuated by the child, or other user, the switch 30 sends a voltage signal to the PCB 56 (shown on FIG. 4 ) resulting in a sound or a series of sounds being generated from the sound transducer 28 , in initiation of the motion sensing feature of the control unit 14 , and in illuminating at least one of the lights.

FIG. 4 illustrates the control unit 14 in greater detail. The control unit 14 further includes a battery case 54 , a top light 58 , the rear light 60 , the PCB 56 , and the motion sensor 62 . The battery case 54 is formed into and inwardly extends from the front housing section 22 of the control unit 14 and includes a removable battery case cover 64 . The battery case 54 is electrically coupled to the PCB 56 by a first wiring connection 66 . The battery case 54 is configured to hold a set of batteries 68 for powering the control unit 14 . In a most preferred embodiment, the batteries 68 comprise three, 1.5 Volt, “AA” size batteries to produce a 4.5 Volt power supply for the control unit 14 . Alternate power supplies and battery sizes can be utilized.

The top and rear lights 58 , 60 are conventional light bulbs, preferably comprising light emitting diodes. The top and rear lights 58 , 60 are mounted to the front and rear housing sections 22 , 24 , and are electrically coupled by second and third wiring connections 70 , 72 , to the PCB 56 , respectively. The top and rear lights 58 , 60 generate light in response to signals from the PCB 56 .

The PCB 56 is a printed circuit board preferably connected to the rear housing section 24 of the control unit 14 . The PCB 56 is electrically coupled to the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 , the lights, the sound transducer 28 , the battery case 54 , and the motion sensor 62 . In a preferred embodiment, the conventional PCB 56 has part number PT-1073A, 000308.

The motion sensor 62 is a motion sensing device. The motion sensor 62 is connected to the rear housing section 24 and is electrically coupled to the PCB 56 through a fourth wiring connection 76 .

FIG. 5 illustrates the control unit 14 in further detail. The control unit includes the sound transducer 28 , a left light 78 and a right light 80 . The sound transducer 28 , also referred to as a speaker, is a sound generating device. The sound transducer 28 is mounted to the rear housing section 24 of the control unit 14 adjacent to openings 27 , and is electrically coupled by a fifth wiring connection 82 to the PCB 56 . The sound transducer 28 generates sounds in response to signals from the PCB 56 . The sounds generated by the sound transducer 28 can include vehicle related sounds, sirens, horns, human voices and other conventional sounds. In a preferred embodiment, the sound transducer is a 16 ohm speaker. The sound transducer 28 can also be of alternate resistance.

The left and right lights 78 , 80 are light bulbs, preferably comprising light emitting diodes. The left and right lights 78 , 80 are mounted to the front housing section 22 , and are electrically coupled to the PCB 56 , respectively. The left and right lights 78 , 80 generate light in response to signals from the PCB 56 .

FIGS. 6 and 7 illustrate the motion sensor 62 in greater detail. The motion sensor 62 includes a housing 84 defining a cavity 85 , four pins forming first and second sets of contacts 86 , 88 , respectively, and a ball 90 . The first and second sets of contacts 86 , 88 are made of a conductive material. The first and second sets of contacts 86 , 88 are spaced apart, and the ball 90 is sized, such that the ball 90 can bridge only one set of contacts at anytime. Each contact of the first and second sets of contacts 96 , 88 is disposed in an approximate vertical position and extend parallel to one another. The first and second sets of contacts 86 , 88 are electrically coupled to the PCB 56 at first and second motion sensor inputs, respectively.

The ball 90 is a spherical object disposed within the cavity 85 between the first and second sets of contacts 86 , 88 . The ball 90 is made of a conductive material, preferably metal. The ball 90 is positionable between a first position in which, the ball 90 bridges the first set of contacts 86 , and a second position, in which the ball 90 bridges the first set of contacts 88 . The PCB 56 then produces an output signal to the sound transducer 28 and to the lights in response to the contact of the ball 90 to one of the set of contacts 86 , 88 and also produces varying signals to the sound transducer 28 and to the lights based upon the rate of contact of the ball 90 with the first and second sets of contacts 86 , 88 . The motion sensor 62 is configured to transmit a signal to the PCB 56 which causes the PCB 56 to send a varying signal to the sound transducer 28 and to the lights, based upon the rate of change of the ball 90 between the first and second positions of the ball 90 .

The variable signal sent from the PCB 56 to the sound transducer 28 and the lights enables the riding toy 10 to directly respond and interact with the motion imparted by the child to the riding toy 10 . The control unit 14 enables a child to control the output of the sound transducer 28 or the lights 58 , 60 , 78 , 80 based upon the child's rate of rocking of the toy rider. In a preferred embodiment, as the child increases the rate of rocking of the riding toy 10 , the control unit 14 emits a louder and different series of sounds from the sound transducer 28 and causes the lights 58 , 60 , 78 , 80 to flash.

In alternative embodiments, the motion sensor 62 can include three or more contacts forming at least two sets of contacts and at least two circuit inputs to the PCB 56 . The ball 90 can be made of alternate shapes such as a cylinder, an irregular shape and a baton. In an alternative embodiment, the motion sensor 62 can be a mercury switch.

Referring to FIGS. 8A and 8B , a preferred embodiment of a circuit diagram for the control unit 14 is illustrated. The PCB includes a circuit comprising a microprocessor 100 , or microcontroller, capable of synthesizing several different human sounds and vehicle sounds, and signaling the lights 58 , 60 , 78 , 80 to flash. The microprocessor 100 includes an internal timer 101 . An example of such a chip is the conventional Winbond BandDirector™ microprocessor model number W562S30. Alternate microprocessors or microcontrollers can be used. The microprocessor 100 is actuated by the switch 30 and the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 . The switch 30 and the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 are connected to trigger inputs 110 , 104 , 106 , 108 , 112 , 114 , 102 of the microprocessor 100 , respectively, such that when the switch 30 or one of the pushbuttons 34 , 36 , 38 , 40 , 42 , 44 triggers the associated trigger input, the microprocessor 100 generates and outputs a transducer controlling signal which corresponds to the switch or the pushbutton chosen.

The microprocessor 100 is powered by a power supply (the batteries 68 ). The collective positive end of the batteries 68 is connected to: a first voltage input 116 of the microprocessor 100 through the resistors 118 , 120 connected in series; and a second voltage input 122 through the resistor 118 . The positive end of the batteries 68 is also connected to the sound transducer 28 and a capacitor 123 . The sound transducer 28 then connects to the collector of a first transistor 124 . The emitter of the first transistor 124 is connected to ground and the base of the first transistor is connected to a speaker input 126 . The base of the first transistor 124 is also connected to a resistor 128 and a capacitor 130 . The battery 68 also connects to first, second, third, fourth and fifth light emitting diodes 132 , 134 , 136 , 138 , 140 . The first and second diodes 132 , 134 are connected in parallel to the collector of a second transistor 142 . The base of the second transistor 142 connects to a first light input 144 through a resistor 146 . The emitter of the second transistor is connected to ground through a resistor 148 . The third, fourth and fifth diodes 136 , 138 , 140 are connected to the collector of the third, fourth and fifth transistors 152 , 154 , 156 , respectively. The base of the third, fourth and fifth transistors 152 , 154 , 156 are connected to second, third and fourth light inputs 158 , 160 , 162 through a resistor 164 , a resistor 166 and a resistor 168 , respectively. The emitter of the third, fourth and fifth transistors 152 , 154 , 156 are connected to ground through a resistor 170 , a resistor 172 and a resistor 174 , respectively. The first and second sets of contacts 86 , 88 of the motion sensor 62 are connected to first and second motion sensor inputs 176 , 178 , respectively.

When the microprocessor 100 outputs a sound signal through the speaker connection 126 , the sound signal is transmitted to the base of the first transistor 124 enabling current to flow through the sound transducer 28 . The sound signal from the speaker connection 126 controls the sound transducer 28 causing it to produce human voice sounds or vehicle related sounds. When the micoprocessor 100 outputs a light signal through one of the diodes 132 , 134 , 136 , 138 , 140 , the light signal is transmitted through the base of the second, third, fourth and fifth transistors 142 , 152 , 154 , 156 enabling current to flow through the diodes 132 , 134 , 136 , 138 , 140 , respectively. The current flow through one of the diodes 132 , 134 , 136 , 138 , 140 causes one of the lights 58 , 60 , 78 , 80 to flash.

When the ball 90 of the motion sensor 62 bridges the first set of contacts 86 an input signal is sent to the first motion sensor input 176 , and when the ball 90 of the motion sensor 62 bridges the second set of contacts 88 , an input signal is sent to the second motion sensor input 178 . The microprocessor 100 sends sound and light signals to the sound transducer 28 and the diodes 132 , 134 , 136 , 138 , 140 . These signals vary based upon the rate of contact by the ball 90 alternatingly bridging the first and second sets of contacts 86 , 88 .

Referring to FIG. 9 , one preferred embodiment of the control system logic of the microprocessor 100 is illustrated. Other logic sequences are conventionally available and would be known to a person of ordinary skill in the art. The switch 30 is activated by the user, indicated at 200 . The microprocessor 100 sends a signal to the left, right and upper lights 78 , 80 , 58 causing the lights 78 , 80 , 58 to flash and the internal timer 101 of microprocessor 100 to energize, indicated at 202 . The microprocessor 100 sends a signal to the sound transducer 28 causing an engine revving sound to be produced, indicated at 204 . The microprocessor 100 senses whether the riding toy 10 is rocking, indicated at 205 . If no rocking motion is present, engine revving sounds continue to be produced for approximately 10 seconds, indicated at 206 and the sound transducer 28 stops, indicated at 208 . This is accomplished through use of the internal timer 101 of microprocessor 100 . When the internal timer of the microprocessor 100 reaches a first timer event, the signal to the sound transducer 28 ceases. In a preferred embodiment, the first timer event is approximately 10 seconds. If some rocking motion is present, the microprocessor 100 determines if the motion is sufficient to produce the next series of output signals, indicated at 210 . If rocking motion is present, but the rocking motion is below a predetermined amount of rocking (or rate of motion or rate between bridging by the ball 90 of the first set of contacts 86 and then the second sets of contacts 88 ), the revving sounds, indicated at 204 , are continued. If the rocking motion is greater than the predetermined amount of rocking, a revving sound of increasing volume is produced for approximately 20 seconds, indicated at 212 . Once the predetermined amount of rocking is reached, the microprocessor 100 produces a signal causing revving sounds at an increased volume to be produced until a second timer event is reached. In a preferred embodiment, the second timer event is approximately 20 seconds. The microprocessor 100 then determines if the amount of rocking is greater than the predetermined level, indicated at 214 . If the amount of rocking is less than the predetermined level, the microprocessor 100 returns to the step indicated at 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 causes the sound transducer 28 to produce siren sounds, indicated at 216 and the left, right and top lights 78 , 80 , 58 to flash, indicated at 218 . When the rocking motion continues beyond the duration of second timer event, the microprocessor 100 causes the sound transducer 28 to produce siren sounds until a third timer event is reached. In a preferred embodiment, the third time event is approximately 10 seconds. The microprocessor 100 determines if the amount of rocking is greater than the predetermined level, indicated at 220 . If the amount of rocking is less greater than the predetermined level, the microprocessor 100 returns to the step indicated at 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 causes the sound transducer 28 to produce an engine revving sound until a fourth time event is reached, indicated at 222 . In a preferred embodiment, the fourth timer event is approximately 10 seconds.

The microprocessor 100 determines if the amount of rocking is greater than the predetermined level, indicated at 224 . If the amount of rocking is less than the predetermined level, the microprocessor 100 returns to the step indicated as 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 causes the sound transducer 28 to produce siren sounds, indicated at 226 and the left, right and top lights 78 , 80 , 58 to flash for approximately 10 seconds, indicated at 228 . The microprocessor 100 then determines if the amount of rocking is greater than the predetermined level, indicated at 230 . If the amount of rocking is less than the predetermined level, the microprocessor 100 returns to the step indicated at 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 causes the sound transducer 28 to produce an engine revving sound for approximately 20 seconds, indicated at 232 . The microprocessor 100 determines if the amount of rocking is greater than the predetermined level, indicated at 234 . If the amount of rocking is less than the predetermined level, indicated at 234 . If the amount of rocking is less than the predetermined level, the microprocessor 100 returns to the step indicated at 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 causes the sound transducer 28 to produce siren sounds for approximately 10 seconds, indicated at 236 and the left, right and top lights 78 , 80 , 58 to flash, indicated at 238 . The microprocessor 100 then determines if the amount of rocking is greater than the predetermined level, indicated at 240 . If the amount of rocking is less than the predetermined level, the microprocessor 100 returns to the step indicated at 205 . If the amount of rocking is greater than the predetermined level, the microprocessor 100 returns to the step indicated at 204 .

Referring to FIG. 10 , another embodiment of the control system logic of the microprocessor 100 is illustrated. The switch 30 is activated by the user, indicated at 300 . The microprocessor 100 sends a signal to the left, right and upper lights 78 , 80 , 58 causing the lights 78 , 80 , 58 to flash and the internal timer 101 of microprocessor 100 is to energize, indicated at 302 . The microprocessor 100 sends a signal to the sound transducer 28 causing an engine revving sound to be produced, indicated at 304 . The microprocessor 100 then determines if motion is present, indicated at 305 . If no rocking motion is present, engine revving sounds continue to be produced for approximately 10 seconds, indicated at 306 , and the sound transducer 28 stops, indicated at 308 . If rocking motion is present, the microprocessor 100 then determines if the elapsed time equals timer event 1 , preferably 10 seconds from the actuation of the switch 30 , indicated at 310 . If no motion is present, the microprocessor returns to step 305 , indicated at 311 . If the rocking motion is present, a revving sound of increasing volume is produced, indicated at 312 .
