Prince Assistant Examiner-Daniel M. Yasich Attorney-Plane, Baxley & Spiecens ABSTRACT: Within the translucent housing of a ball, there is an inertia switch which is connected to a lighting unit. The lighting unit includes a lamp and a battery which can be connected to form a series circuit by a time delay switch When ever the normally open inertia switch activates the time delay switch it closes the series circuit for a given period of time ILLUMINABLE BALL WITH A TIME DELAY DEVICE This invention pertains to illuminable toys and, more particularly, to illuminable balls.

Illuminable balls have been available in the past as toys. Such balls generally fall into two categories. The type employing some sort of toggle switch which is used to manually turn on the lamp within the ball at the start of play and to turn it off at the end of play so that the ball remains continuously illuminated until the player extinguishes the lamp. Thus, electrical energy is consumed only during the period of play. However, such balls are inconvenient because the player must have easy access to the switch. The other type uses an intermittently operated switch which opens and closes in response to the motion of the ball. Such balls are only intermittently illuminated and provide a flickering effect.

It is, accordingly, an object of the invention to provide an illuminable ball which will light up only when being played with and does not require the player to manually operate a toggle switch or the like.

Briefly, the invention contemplates an illuminable ball comprising a housing of material which at least partially transmits light. Within the housing there is an inertia switch which shifts between two states of conductivity. Also, there is within the housing a lighting unit which includes at least one battery and one lamp. A time delay switching means within the housing is responsive to the changes in state of the inertia switch to connect the battery to the lamp for a given period of time each time the inertia switch shifts in a particular way between the states of conductivity.

Other objects, the features and advantages of the invention will be apparent from the following detailed description when read with the accompanying drawing which shows the presently preferred embodiment of the invention.

In the drawings:

FIG. I shows a perspective view of an illuminable ball with a portion of the housing broken away;

FIG. 2 is a view similar to that of FIG. I but rotated 90 of a portion of the ball;

FIG. 3 is a side view of an inertia switch incorporated in the ball of FIG. 1; and

FIG. 4 is a schematic diagram of the illuminating circuitry for the ball of FIG. I.

In FIGS. 1 and 2 an illuminable ball I is shown having a housing comprising two hemispheres l2 and I4 of a high-im' pact translucent plastic. The hemispheres are preferably provided with mating peripheries (not shown) which permit access to the interior of the ball. The peripheries can be, for example, screw threaded or can be provided with snap-fitting lips. Extending radially inward from the inner walls of the hemispheres are mounting brackets 16 and 18. One end of each bracket is fixed to the inner surface of one of the hemispheres. The other end of each bracket is fixed to a lighting unit 20. Lighting unit 20 comprises a chassis 22 with polarized deformations 24 and 26 for engaging battery 28. Flanges 29 and 31 on the chassis include sockets for supporting lamps 30 and 32. Chassis 22 also supports a printed circuit card 34 containing electronic elements hereinafter more fully described.

Fixed to the inner surface of hemisphere I2 is inertia switch 40 shown in greater detail in FIG. 3. Switch 40 comprises spacers 42 to support insulators 44 and 46. Insulator 44 supports a loop-shaped conductor 48 having a terminal 50 at one end. Insulator 46 supports a resilient rod member 52 having one end passing through the loop of conductor 48 and having a terminal 53 at one end. A mass member 54 is fixed to the other end of the rod member 52. A contoured support 56 carries the entire switch and providesa contact surface for fixing the switch 40 to hemisphere 12. Finally, terminals 50 and 53 are connected via wires 60 and 58, respectively, to printed circuit card 34 of lighting unit 20.

Printed circuit card 34 supports the electronic elements shown in FIG. 4. In particular, the electronics comprises a time delay switching circuit centered around transistor 70 having a collector electrode 72 connected to one end of the serial circuit of lamps 30 and 32, an emitter electrode 74 connected to the negative terminal of battery 28 and a base electrode connected via resistor 78 and wire 60 to terminal 50 of inertia switch 40. A capacitor 80 connects one end of resistor 78 to the emitter electrode 74. The positive terminal of battery 28 is connected, via wire 58, to terminal 53 of inertia switch 40, and also, via lead 82, to the other end of the series circuit oflamps 30 and 32.

The operation of illuminable ball 10 will now be described by making reference to FIGS. 3 and 4.

Initially, with the ball at rest or not accelerating, inertia switch 40 is open and transistor is nonconducting. Whenever there is an acceleration, rod member 52 at least momentarily contacts loop-shaped conductor 48 closing switch 40. Charging current flows from the positive terminal of battery 28 via switch 40 to capacitor 80, raising the voltage of the base electrode 76. Transistor 70 switches to the conducting state and the following circuit is established: positive terminal of battery 28, lead 82, lamps 30 and 32, transistor 70 to the negative terminal of battery 28. This circuit is maintained as long as the voltage at the base electrode is sufficiently positive. The required voltage will be present as long as switch 40 is closed. When switch 40 opens, the required voltage will be maintained until the charge on capacitor leaks off via resistor 78 and the base emitter junction of transistor 70. By making the time constant of the resistor-capacitor combination sufficiently large the transistor will remain conducting for a relatively long time. Thus, any intermittent closure of switch 40 will merely resupply any leaked off charge and transistor 70 will remain conducting until a given period of time after the last opening of switch 40. Accordingly, as long as the ball is being moved it will remain lighted without any flicker and will only go out when put down.

While only one embodiment of the invention has been shown and described in detail various modification can be made without departing from the spirit of the invention. For

example, more than one battery can be used to increase the life of the device before battery replacement is required.
