ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to a system for pleasurable use by people of all ages with youthful minds in operating remotely controlled vehicles simultaneously in a somewhat confined area. More specifically, this invention relates to remotely controlled vehicles such as toy dump trucks that can be operated to mimic the operation of similar full-size vehicles having accessories for scooping up material, transferring the material to a hopper, and then automatically activating the hopper to dump the material. In addition, the system also includes a trailer hitch that can be remotely engaged or disengaged by controlling the position of the scooper.
2. Description of the Related Art
Various types of play systems exist, and have existed for some time, in which vehicles are moved on a remotely controlled basis. Examples of a vehicle in such a system are an automobile, airplane, truck or construction vehicle. In most such systems, however, the functions and activities that the vehicle is capable of are limited to moving along a floor or along the ground or in the air.
Other types of play systems involve the use of blocks for building structures. These blocks often include structure for providing an interlocking relation ship between abutting blocks. In this way, elaborate structures can be created by users with creative minds. Such structures are generally built by hand.
Tests have indicated that there is a desirability, and even a need, for play systems in which vehicles are remotely operated to perform functions other than to move aimlessly along a floor or along the ground. For example, tests have indicated there is a desirability, and even a need, for a play system in which the remotely controlled vehicles can transport elements such as blocks to construct creative structures. There is also a desirability, and even a need for play systems in which aplurality of vehicles can be remotely controlled by switches in hand-held pads to compete against one another in performing a first task or to cooperate in performing a second task such as building a miniature community through the transport of miniature blocks or other suitably sized material.
Application Ser. No. 08/580,753 (now U.S. Pat. No. 5,944,607) filed by John J. Crane on Dec. 29, 1995, for a “Remote Control System for Operating Toys” and assigned of record to the assignee of record of this application discloses and claims a play system for use by people of all ages with youthful minds. It provides for a simultaneous control by each player of an individual one of a plurality of remotely controlled vehicles. This control is provided by the operation by each such player of switches in a hand-held unit or pad, the operation of each switch in such hand-held unit or pad providing a control of a different function in the individual one of the remotely controlled vehicles. Each of the remotely controlled vehicles in the system disclosed an claimed in application Ser. No. 08/580,753 (now U.S. Pat. No. 5,944,607) can be operated in a competitive relationship with others of the remotely controlled vehicles or in a co-operative relationship with others of the remotely controlled vehicles. The vehicles can be constructed to pick up and transport elements such as blocks or marbles and to deposit such elements at displaced positions.
When manually closed in one embodiment of the system disclosed and claimed in application Ser. No. 08/580,753 (now U.S. Pat. 5,944,607), switches in pads control the selection of toy vehicles and the operation of motors for moving the vehicles forwardly, rearwardly, to the left and to the right and moving upwardly and downwardly (and rightwardly and leftwardly) a receptacle for holding transportable elements (e.g. marbles) or blocks.
When sequentially and cyclically interrogated by a central station, each pad in the system disclosed and claimed in application Ser. No. 08/580,753 (now U.S. Pat. 5,944,607) sends through wires to the central station signals indicating the switch closures in such pad. Such station produces first binary signals addressing the vehicle selected by such pad and second binary signals identifying the control operations in such vehicle. Thereafter the switches identifying in such pad the control operations in such selected vehicle can be closed without closing the switches identifying such vehicle.
The first and second signals for each vehicle in the system disclosed and claimed in application Ser. No. 08/580,753 (now U.S. Pat. 5,944,607) are transmitted by wireless by the central station to all of the vehicles at a common carrier frequency modulated by the first and second binary signals. The vehicle identified by the transmitted address demodulates the modulating signal and operates its motors in accordance with such demodulation. When the station fails to receive signals from a pad for a particular period of time, the vehicle selected by such pad becomes available for selection by another pad and such pad can select that vehicle or another vehicle.
A cable may couple two (2) central stations (one as a master and the other as a slave) in the system disclosed and claimed in application Ser. No. 08/580,753 (now U.S. Pat. 5,944,607) so as to increase the number of pads controlling the vehicles. Stationary accessories (e.g. elevator) connected by wires to the central station become operative when selected by the pads.
Co-pending application Ser. No. 08/763,678 (now U.S. Pat. 5,888,135), filed by William M. Barton, Jr., Peter C. DeAngelis and Paul Eichen on Dec. 11, 1996 for a “System For And Method Of Selectively Providing The Operation Of Toy Vehicles” and assigned of record to the assignee of record of this application discloses and claims a system wherein a key in a vehicle socket closes contacts to reset a vehicle microcontroller to a neutral state. Ribs disposed in a particular pattern in the key operate switches in a particular pattern in the vehicle to provide an address for the vehicle with the vehicle inactive but powered. When the vehicle receives such individual address from an individual one of the pads in a plurality within a first particular time period thereafter, the vehicle is operated by commands from such pad. Such individual pad operates such vehicle as long as such vehicle receives commands from such individual pad within the first particular period after the previous command from such individual pad. During this period, the vehicle has a first illumination to indicate that it is being operated.
When the individual pad of the system disclosed and claimed in application Ser. No. 08/763,678 (now U.S. Pat. 5,888,135) fails to provide commands to such vehicle within such first particular time period, the vehicle becomes inactive but powered and provides a second illumination. While inactive but powered, the vehicle can be addressed and subsequently commanded by any pad including the individual pad, which thereafter commands the vehicle. The vehicle becomes de-activated and not illuminated if (a) the vehicle is not selected by any of the pads during a second particular time period after becoming inactivated but powered or, alternatively, (b) all of the vehicles become inactivated but powered and none is selected during the second particular period. The vehicle becomes de-activated and not illuminated. The key can thereafter be actuated to operate the vehicle to the inactive but powered state.
Co-pending application Ser. No. 08/696,263 (now U.S. Pat. 5,885,159), filed by Peter C. DeAngelis on Aug. 13, 1996 for a “System And Method Of Controlling The Operation Of Toys” and assigned of record to the assignee of record of this application discloses and claims a system wherein individual ones of pads remotely control the operation of selective ones of vehicles. In each pad, (a) at least a first control provides for the selection of one of the vehicles, (b) second controls provide for the movement of the selected vehicle and (c) third controls provide for the operation of working members (e.g. pivotable bins) in the selected
