Abstract:
A switch device includes two contactors. Each contactor respectively includes at least two conductors, a magnet, and a coil spring. The conductors are connected to a power source via a powered electronic circuit. The circuit is designed to be in a normally open or closed initial condition. The magnet is directly or indirectly connected to the conductors. The coil spring is directly or indirectly located between the conductors and the magnet. The conductors change their normally open or closed condition into a temporarily closed or open condition to turn on or off the switch device when the contacts move near enough to permit magnets to interact magnetically. The coil spring forces the conductors to recover their original normally open or closed condition when the magnets cease to interact magnetically.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a switch device, and particularly to one consisting of two contactors having two conductors in a normally open or closed condition, the two conductors being changed into a temporarily closed or open condition so as to turn on or off the switch device for starting movement of two things provided with the two contactors. 
     Communication and contact are a crucial element in social activities, and every one should pay attention to the way and etiquette of communication and contact with other people. Especially, young children should be trained in these matters from an early age for leading and correcting social tendency and behavior. Toy dolls delightful to children are designed and manufactured independently, and are made to exhibit various movements such as blinking, extending hands, kicking with feet, or speaking out words, and so forth. But such movements are always done by a single doll, with no corresponding mutual talking or action between two dolls. There are no such two dolls capable of talking to each other, singing, or even kissing or expressing lovable action. 
     SUMMARY OF THE INVENTION 
     This invention has been devised, depending on two separate things, which moves nearer each other for contacting each other and making corresponding action or movement or sounds or talk. Thus children may play and learn from those dolls how to talk, to act or to sing, by arousing their curiosity. 
     One object of the invention is to offer a switch device consisting of two contactors respectively containing two strip conductors in an initial normally open or closed condition. 
     Another object of the invention is to offer a switch device which makes it possible to control two things such as dolls in making action, movement, singing, talking, etc. to enhance interest.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A first embodiment of a switch device of the present invention, as shown in FIG. 1, is applied in two boxing gloves (a thing), which are located to contact with each other before the two boxers may also exchange dialogue, using threatening words or praise, but the exchange of dialogue is not included in the present invention. 
     As shown in FIG. 2, a contactor  10  is provided inside each boxing glove A, and the two contactors  10  will be turned on to let a sound device contained in the two boxers&#39; bodies produce verbal words as along as the two contactors move nearer each other enough to a preset position. The verbal words produced by the sound device may be set in advance, and the time needed also has to be preset. But of course, the verbal words can coordinate with physical movements to enhance its effect. These matters are riot included in the present invention. 
     Two of the contactors  10 , as shown in FIGS. 3 and 4, constitute the switch device according to the present invention, including a housing  11  consisting of two halves and having its interior divided into a front, an intermediate and a rear space  13 ,  14  and  15  by means of separating walls. The first separating wall between the front space  13  and the intermediate space  14  has a first hole for communicating the two space  13 ,  14 . There is also a second hole in the second separating wall between the intermediate space  14  and the rear space  15 . 
     Each contactor  10  further has a movable member  16  consisting of a head  161  and a shaft  162  formed integrally with the head  161 , and a head  163  and a shaft  164  formed integrally with the head  163 . The head  161  is located in the front space  13 , with the shaft  162  passing through the first hole and extending in the intermediate space  14 . A coil spring  17  is provided to fit around the shaft  162 , with one end resting on the first separating wall. The head  163  is located just behind the rear end of the shaft  162 , with the rear end of the coil spring  17  resting on the head  163 . The shaft  164  passes through the second hole of the second separating wall between the intermediate and the rear space  14  and  15  and extends into the rear space  15 . A disc conductor  18  (preferably made of a metal) is provided and fixed with the rear end of the shaft  164 . Further, a magnet  19  is fixed with a front surface of the head  161 . 
     Each contactor  10  further includes two strip conductors  1 A,  1 B, pinched between the walls of the housing  11  with one end extending out of the housing  11 , and the other end extending in the rear space  15  and bent a little beyond the disc conductor  18 . In the normal condition, the two contactors  10  are not located in the contact position, but are elastically pushed by the coil springs  17 . So each contactor  10  is in the normally off condition as shown in FIG. 4, with the disc conductor  18  being separated from the two strip conductors  1 A,  1 B. 
     Next, as shown in FIG. 5, if the two contactors  10  move nearer each other to a preset contact position (wherein the two magnets  18  in the two contactors  10  may Produce mutual a magnetic attractive force), the two movable members  16  of the two contactors  10  move forward axially at the same time against the two coil springs  17  by means of attraction of the different poles of the two magnets  19 , forcing the two strip conductors  1 A,  1 B of both the contactors  10  to contact the disc conductor  18  to turn on the switch device. The closed circuit causes the boxing gloves to sound or speak out and move physically for once, with the contactors  10  functioning as electrical terminals. The two things (such as boxing gloves, dolls. etc.) may sound, speak and move synchronously by concurrent turning-on action of the two contactors  10 . Further, a delay function may enable the subsequent action to continue, so turning-on once may cause a whole set of preset sounds or physical movement finish, despite the two contactors  10  having already separated to turn off the switch device. The two contactors  10  recover the normally off position shown in FIG. 4 when they move away from the preset contact position and the two magnets  19  are no longer able to attract each other. Meanwhile, dialogue and action of the two things may be kept on to the end. 
     Further, a switch device May not be limited -to the structure shown in FIGS. 3,  4  and  5 . FIG. 6 shows a second embodiment of a switch device in the present invention including two contactors  20  respectively consisting of a housing  21  made up of two halves, a movable member  26 , a coil spring  27 , a disc conductors  28 , a magnet  29 , and two strip conductors  2 A,  2 B. But the interior of the housing  21  is divided into two spaces, a front one  23 , a rear one  25 , by a separating wall. The movable member  26  consists of a head  261 , and a shaft  262  formed integral with the head  261 . The magnet  29  is fixed firmly on a front surface of the head  261 , and the coil spring  27  is fitted around the shaft  262 , with one end resting on the head  261  and with the other end resting on the separating wall of the spaces  23 ,  25 . The rear end of the shaft  262  passes through a hole of the separating wall to extend in the rear space  25  and then is fixed firmly with the disc conductor  28 . The two strip conductors  2 A,  2 B are pinched in the housing  21  and their r outer ends extend out of the housing  21 , with their inner bent ends located near the two sides of the disc conductor  28 , as shown in FIG. 6, the two bent ends being in a separated condition relative to the disc conductor  28 . 
     As to the function of the second embodiment, as shown in FIG. 7, if the two contactors  20  are moved nearer each other to a preset position, the repelling force of the same poles of the two magnets  29  push the movable members  26  rearward against the coil springs  27 , forcing the disc conductor  28  to contact the two strip conductors  2 A,  2 B to turn on the contactor  20 . 
     The contactors  10 ,  20  in the first and the second embodiments are turned on by axial movement of the movable members  16 ,  26 . But practically the invention is not limited to axial movement to effectuate a turning on action. A third embodiment of a switch device shown in FIGS. 8 and 9 includes a housing  31  of a non-cylindrical shape, but having a large space portion  33  and a small space portion  35  continually formed together. Further, the switch device of the third embodiment includes a pair of strip conductors  3 A,  3 B extending firmly inside the smaller space portion  35  on two side walls and having outer ends extending out of the housing  31 . One strip conductor  3 A has its inner end bent near the other strip conductor  3 B, which extends into the large space  33  and is fixed firmly to a magnet  39 . 
     In using the third embodiment of a switch device, as shown in FIG. 9, the two large space portions  33  of the two (contactors  30  are moved nearer each other, permitting the two magnets  39  of both the contactors  30  to attract each other with the same poles, forcing the strip conductors  3 B to bend forward to contact the other strip conductors  3 A, turning on the contactors  30 . As the strip conductors  3 A,  3 B are all elastic, the conductors  3 B may recover its elasticity to bounce back to its normal position the two strip conductors  3 A,  3 B being in off condition after the two contactors  30  are separated away from each other. 
     Further, a fourth embodiment of a switch device is shown in FIGS. 10 and 11, having the same structure as the third embodiment, except that the two strip conductors  4 A,  4 B are located nearer each other, with the two poles of the two magnets  49  being the same to repel each other rather than to attract each other as in the third embodiment, forcing the strip conductor  4 A to bend to contact the other strip conductor  4 B. It goes without saying that the strip conductors  4 A,  4 B are all elastic. 
     The structure of the first and the second embodiment which uses axial movement in turning on the contactors is preferably applied to boxing dolls shown in FIG.  1 . In addition, it can also be applied to a male and a female doll performing a kiss as shown in FIG. 12, wherein the contactors are provided at the lips so that the contactors are turned on and sound out talking when the two dolls move near to kiss each other. The third and the fourth embodiment can be applied to glove-shaped toys shown in FIGS. 9 and 11. When the two glove-shaped toys move nearer each other, the contactors hidden inside can be turned on to move them and let them talk. 
     Those embodiments of the first to the fourth are all hidden in something such as dolls, boxing gloves, etc., but they can be installed in other ways, as shown in a fifth embodiment illustrated in FIG.  13 . The fifth embodiment includes a housing  51 , two strip conductors  5 A,  5 B contained in one side in the housing  51 , an insulating member  5 C located between the two conductors  5 A,  5 B, and a magnet  59  fixed on an outer end of the conductor  5 B which is made of an elastic material. Further, a circuit board  5 D is provided in another side in the housing  51 , and a loud speaker  5 E, an IC  5 F and a power source  5 G are positioned on the circuit board  5 D. All the components are contained in the housing, as the conductors  5 A,  5 B are connected to the circuit board  5 D. The two conductors  5 A,  5 B, and the magnet  59  constitute a contactor as described above, and the circuit board  5 D, the loud speaker  5 E, the IC  5 F and the power source  5 F are not the components of the contactor, but rather than elements for the thing (such as a doll, a boxing glove, etc., and ) are only contained in the the same housing  51 . When the two things move near each other, the two magnets  59  in the two things may attract each other to turn on the circuit. As a result the contactor is not necessarily hidden in a thing, nor does it need to have a housing, but can be designed to have a housing as a conductor. The various embodiments described above have the conductors always normally open to cope with the magnets mutually attractive or repellent so as to let them contact each other for turning on the switch device. In a practical appliance, conductors in a normally closed initial condition can also be used to let the contactors turn off by the magnets attracting or repelling each other so that the thing provided with the contactor may be controlled in its action. Of course, using attraction or repelling of the magnets is dependent on the electronic circuit used in the thing. In addition, the number of the conductors may not be limited to two, but may be more if needed. 
     In short, the present invention uses two contactors to constitute a switch device, and when the two contactors are moved near enough to a proper position, the magnets in the two contactors attract or repel each other to start corresponding movement of the two things having the contactors. The corresponding movement means that the two things have further movement after starting, and the separate movement of the two things may be related or not related to each other. i.e. may indepedently accomplish their own movement. Of course, their movement may be slow, quick, long or short, depending on design. Further, the movement of the things may include real dynamic action and static action (for example, starting two independent power sources or an electronic circuit being powered). The things are not limited, even simplified to have the contactor forming a large portion of a thing. The main movement and function of the present invention is effected by the two contactors constituting the switch device, which is turned on by means of the two contactors moving nearer each other to a preset position, and thereby activating two independent powers or an electronic circuit being powered for producing movement, and talking of the things. 
     While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
