## Title
Controller for electrical toy vehicle

## Abstract

A toy vehicle controller include a casing with a grip (1) topped by a widened zone (2). A resistance element (3) is mounted in the widened zone (2), and it provides a variable resistance depending on a position of a cursor (4) that moves under the action of a trigger (5). A first arm (16) and a second arm (17) of the cursor touch opposite sides of the resistance element (3). A first wire (6) is connected to a first terminal (10), and the resistance element (3) is coupled to the first terminal (10). A second wire (7) is connected to a second terminal (11), and the second terminal (11) is couple to the cursor (4). As the trigger is depressed, the first and second arms of the cursor move along the resistance element to vary a resistance in the circuit formed between the first and second wires. When a user depresses a button (15), the head (20) of an elastic element (13) is pushed into contact with the first terminal (10). If the first arm (16) of the cursor (4) is in electrical contact with the elastic element (13), this effectively short circuits the first and second wires, removing the resistance element (3) from the circuit, and delivering all available voltage to the toy vehicle.

## Background
BACKGROUND
1. Field
The invention relates to controllers which are used to control the speed of electrical to vehicles.
2. Background
It is known to use hand-held controllers for controlling the speed of electrical toy vehicles. Such controllers typically have a trigger which increases or decreases the speed of such toy vehicles depending on how far the trigger is depressed.
U.S. Pat. No. 3,705,387 entitled “Remote control system for electro-mechanical vehicle,” dated 1971, in the name of Mr. Kenneth Stern et al., discloses a remote electronically controlled vehicle which is movable between two conductive tracks. The vehicle is equipped with electrical control devices for steering and driving of the vehicle. The toy vehicle is connected to conducting contacts on the track surfaces. The conducting track is equipped to handle a plurality of these vehicles through a single electronic control unit having a multiple channel FM telemetry circuit including an oscillator and mixer circuit. Multiple individual manual controls corresponding to the number of vehicles on the conductive tracks can be attached to the control unit for individual independent control of the vehicles on the conductive tracks.
Spanish Utility Model No. 9801722 (ES1040729), dated 1998, discloses a controller for toy cars. The controller includes a housing that forms a hand grip, topped by a wider area that houses a variable resistance element. The resistance varies depending on the position of a cursor, which is moved by the action of a trigger mounted on the casing. The resistance element and the cursor are connected to a corresponding power terminal. The resistance element is mounted on a block, which provides a shelter, and it is fixed by screws.
U.S. Pat. No. 4,112,615, entitled “Remote control system for a movable toy vehicle,” discloses a wireless transceiver control system for motor driven toy vehicle. The device has a transmitter for generating a predetermined carrier of selected high frequency, and a receiving unit including a super-regenerative detection circuit for receiving the high frequency carrier. A relay switch, for reversing the power to the electrical motor driving the toy vehicle, can be energized by the amplified noise signal to retain the switch in one position and release a relay to a second position. A gear train drives the vehicle in one direction when the switch is in one position, and it drives the vehicle in the same direction and also turns the wheels of the vehicle when the switch is in the second position.

BRIEF DESCRIPTION OF THE DRAWINGS
The embodiments will be described in detail with reference to the following drawings, in which like reference numerals refer to like elements, and wherein:
FIG. 1 is a diagram showing the elements mounted in a top portion of a first embodiment of a toy vehicle controller; and
FIG. 2 is a perspective view showing the elements circled by line II in FIG. 1.



DETAILED DESCRIPTION
FIG. 1 illustrates the top portion of a controller for a toy vehicle. The controller includes a grip 1, a zone widened 2, and a resistance element 3. A cursor 4 includes a first arm 16 and a second arm 17. The cursor is coupled to a trigger 5 which can be depressed by the user. The controller further include a first cable 6, a second cable 7, a first terminal 10, a second terminal 11, a badge 12, an elastic extension 13 and head 20, a push-button 15 with its projection 14 and a protuberance 18.
The resistance element 3 has one end connected to the first cable 6 and the first terminal 10. The cursor 4, which is coupled to the trigger 5, is connected to the second cable 7 through the second terminal 11. The arms 17,18 of the cursor 4 are positioned on either side of the resistance 3. Depressing the trigger 5 causes the arms 17,18 to move along the resistance element toward the first terminal 10, thereby reducing the value of electrical resistance between the first cable 6 and the second cable 7. Thus, in turn, increasing the voltage delivered to the toy vehicle being controlled by the controller. Increasing the voltage delivered to the electric vehicle toy increases its speed on the track.
The first arm 16 of the cursor 4 is provided between the badge 12 and the resistance element 3. In this embodiment, the badge 12 is inclined relative to the resistance element 3. An insulating element 19 is positioned between the badge 12 and the terminal 10, as shown in FIG. 2, which prevents contact between the two.
As the trigger 5 is depressed, the cursor 4 moves toward the terminal 10. Because the badge 12 is inclined relative to the resistance element 3, at some point during the cursor's travel, the back side of the first arm 16 comes in contact with the badge 12. This has no immediate effect, as the electricity must still pass from the first terminal 10, down the resistance element 3, into the first and second arms 16, 17 and then to the second terminal 11.
However, once the cursor has moved to a position where the first arm 16 is in contact with the badge 12, the user can push a “turbo” button 15 to suddenly increase the voltage delivered to the toy vehicle. The button 15 has a projection 14 that contacts the elastic extension 13 of the badge 12. The elastic extension 13 ends in a head 20, which confronts with the first terminal 10. When a user pushes the button, the projection 14, in turn, pushes the elastic extension 13 such that the head 20 comes into contact with the first terminal 10. This eliminates the resistance element 3 from the circuit so that all of the available voltage can be delivered to the toy vehicle, providing maximum speed. When the user releases the button 13, the head 20 no longer makes contact with the terminal 10, and the resistance element 3 is introduced back into the circuit.
To facilitate contact between the badge 12 and the resistance element 3, the first and second arms 16, 17 of the cursor 4 may include bumps 18 on their ends.
