The present invention relates generally to children's ride-on vehicles. More specifically, the invention concerns a simplified shifter design which allows a child to select between varying speeds and directions such as high speed forward and low speed forward and reverse. The invention mechanically precludes the selection of undesirable speeds and directions, such as high speed reverse.
In the last few years, ride-on vehicles having motors, intended for use by children have become popular toys. These toys come in many shapes and sizes depending on the age and size of a particular child. Typically, the ride-on vehicles will have a battery source connected to an electric motor which drives one or more of the vehicle's wheels according to the speed and direction selected by the child.
To operate the vehicle, a child will sit on or within the vehicle, and by pressing a pedal or moving a switch on a control panel, the vehicle's motor is energized by the battery source and the vehicle is driven by the child in much the same way an adult operates an automobile.
Most vehicles have more than one speed and several have more than one direction. In vehicles having more than one speed, there is usually a fast and a slow speed. In vehicles having more than one direction, the second direction is usually reverse.
It is well known that a high speed reverse mode is undesirable because a child cannot see where they are going. Conventional attempts have been made to eliminate this setting or reduce the chances of inadvertently selecting it. One such attempt is U.S. Pat. No. 5,173,591 to Perego which discloses a gear shift connected to two rotatable elements. The rotatable elements have a spring therebetween and are designed to selectively contact a speed and direction switch, which in turn select connections between an electric motor and a set of batteries to achieve multiple running modes. Perego precludes a high speed/reverse mode by allowing reverse to be selected only when the speed switch is in the low position and the force of a spring acting between the rotatable elements is overcome by a rider moving the shift. Thus, to enable only a low speed/reverse mode, Perego employs: two different types of switches (one having two fixed positions and one having only one fixed position), two rotatable elements, and a spring acting therebetween.
While it is desirable to preclude the high speed reverse mode, it is also desirable to reduce the number of elements and moving parts necessary to do so and to provide a design which is inexpensive to manufacture and easy to assemble. The design must be durable enough to withstand the often times destructive way that a child uses the vehicle. It is also desirable to provide a ride-on toy in which the high/forward setting can be disabled until the child learns how to correctly and safely operate the vehicle at slower speeds.
With the above problems in mind, a general object of this invention is to provide a child's ride-on vehicle which has a shifter design connected between a power source and a motor source which enables a child to select between desired speeds and directions and precludes the selection of undesired speeds and directions.
It is another object of this invention to provide a housing and shifter design which may be used in a child's ride-on vehicle to enable a child to select between a high/forward, a low/forward and a low/reverse mode of operation while precluding the selection of a high/reverse mode.
Another object of the invention is to provide a shifter design which is inexpensive to manufacture and durable enough to withstand the use to which it may be put by a child.
The invention achieves these and other objects in the form of a simplified shifter which reduces the number of components necessary, utilizes the same type of switch for both the direction and speed control, and provides for a switch contact surface which complements the structure of a gear actuator or selector to ensure that the desired mode is selected.
The shifter design in the preferred embodiment of the invention features a housing or casing on which two rocker switches are housed: a high/low switch and a forward/reverse switch. The switches are connected between a battery source and plural motors and are adjacent one another. An actuator or shifter is pivotally mounted to the housing and moved in a plane parallel to the pivot axes of the switches. The actuator has a depending selection member with longitudinally-spaced annular structure for selectively contacting the switches upon movement of the shifter by the rider. The high/forward setting corresponds to a parallel connection between the plural motors and the low/forward and low/reverse settings correspond to a series connection between the plural motors. The switches are positioned to preclude a high/reverse setting. Hence, a child riding on the toy in which the shifter is configured, may select between only three distinct modes of operation: high/forward, low/forward and low/reverse. Further, a removable stop element is provided and may be used by an adult to prevent the child from selecting the high/forward mode, until the child learns to control the vehicle at lower speeds.
In an alternative embodiment of the invention, the shifter features an actuator slidably mounted to the housing adjacent the speed and direction switches. The actuator slides in a path generally parallel to the pivot axes of the speed and direction switches and includes an elongate selection member, transverse the slide path of the actuator, for selectively contacting the switches.
These and additional objects and advantages of the present invention will be more readily understood after a consideration of the drawings and the detailed description of the preferred and alternative embodiments.
