This invention relates generally to a child's riding vehicle and, more particularly, to a vehicle for a child that can be operated at different speeds (i.e., fast and slow) and in different directions (i.e., forward and reverse).
Children enjoy mimicking adult behavior and the driving of vehicles is certainly no exception. For this reason, riding vehicles, and especially those modeled after cars and trucks driven by adults, are appealing to children. A child's riding vehicle will typically comprise a vehicle body adapted to carry a child, wheels rotatably connected to a drive assembly for driving the wheels. A shifter can be provided to allow operation of the vehicle at different speeds (e.g., fast and slow) and/or in different directions (i.e., forward and reverse).
A child's riding vehicle comprises a vehicle body adapted to carry a child, wheels rotatably connected to the drive assembly, a drive assembly for driving the wheels, and a shifter for shifting the drive assembly among a forward-high condition (whereat it drives the wheels forward at a high speed), a forward-low condition (whereat it drives the wheels forward at a low speed), and a reverse-low condition (whereat it drives the wheels in reverse at a low speed).
The shifter comprises a direction switch including a toggle movable between a forward-direction position and a reverse-direction position, a speed switch including a toggle movable between a high-speed position and a low-speed position, and actuator. The direction switch is in the forward-direction position when the drive assembly is in the forward-high condition and the forward-low condition and the direction switch is in the reverse-direction position when the drive assembly is in the reverse-low condition. The speed switch is in the high-speed position when the drive assembly is in the forward-high condition, and the speed switch is in the low-speed position when the drive assembly is in the forward-low condition and when the drive assembly is in the reverse-low condition.
The shifter further comprises an actuator that is movable among a forward-high setting, a forward-low setting, and a reverse-low setting. When moved from setting to setting, the actuator interacts with the direction switch and the speed switch to shift the drive assembly among the forward-high condition, the forward-low condition and the reverse-low condition. To this end, the actuator can include a direction-switch-interacting slot, into which the direction switch toggle is inserted when it is moved between the forward-direction position and the reverse-direction position, and a speed-switch-interacting slot, into which the speed switch toggle is inserted when it is moved between the high-speed position and the low-speed position. Additionally or alternatively, the actuator can be pivotal about a pivot axis that is substantially parallel with the pivot axes of the direction and speed switch toggles.
When the actuator is moved between the forward-high, forward-low, and the reverse-low settings, the direction and speed switch toggles move between their front and rear positions. Because of the parallel arrangement of the pivot axes, the movement of the actuator translates into motion in the same parallel direction for the switch toggles. This movement of the actuator can provide a child who is driving the vehicle with a gear-shifting-feel that accurately resembles the sensation of shifting gears in an adult-size vehicle.
These and other features of the invention are fully described and particularly pointed out in the claims. The following description and annexed drawings set forth in detail a certain illustrative embodiment of the invention, this embodiment being indicative of but one of the various ways in which the principles of the invention may be employed.

The vehicle body 12 is typically formed of a plurality of molded, rigid, plastic parts that can be glued, melted or screwed together with suitable fasteners and can be adapted to include many of the features found in automotive vehicles driven by adults. For example, the illustrated vehicle 10 includes two seats 18, each sized to receive a seated child, and a dividing island 20 positioned between the seats 18. A floor 22 extends from the seats 18 to the region of the vehicle body 12 forming the dashboard 24.
The drive assembly 16 can comprise motor means, a power source for powering the motor means, and other components (e.g., linkages, axles, cables, etc.) for establishing operative interconnection between the wheels 14 and the motor means. In the illustrated embodiment, the motor means comprises motors 30 and 32 and the power source comprises a battery 34. A foot switch (not shown), or other activating means, can be provided for selective energization of the motor means 30/32 by a child.
The drive assembly 16 further comprises a shifter 40 which is operably coupled between the motor means 30/32 and the power source 34. The shifter 40 allows shifting of the drive assembly 16 among a forward-high condition whereat it drives the wheels 14 forward at a high speed, a forward-low condition whereat it drives the wheels 14 forward at a low speed, and a reverse-low condition whereat it drives the wheels 14 in reverse at a low speed. Preferably, the shifter 40 precludes a condition whereat the drive assembly 16 drives the wheels 14 in reverse at a high speed.

The housing walls 44 and 46 form a chamber for internal components of the shifter 40. As is best seen by referring briefly back to
The top wall 46 has a slot 56 and an indent channel 58 positioned roughly parallel therewith. The slot 56 is sized/shaped so that an actuating portion of the shifter 40 (namely an actuator handle portion 126, introduced below) can extend therethrough and be moved therewithin to control the setting of the shifter 40. The indent channel 58 can be labeled with indicia identifying the different settings of the shifter 40, specifically, for example, a “2” for the setting corresponding to the forward-high condition, a “1” for the setting corresponding to the forward-low condition, and a “R” for the setting corresponding to the reverse-low condition.

The frame 70 comprises a main plate 80 having a shape generally corresponding to the chamber formed by the housing walls 44/46. Three cylindrical screw holders 82 extend perpendicularly from the main plate 80 and are arranged for receipt of the fastening screws 60. The frame 70 can further comprise a flange on upper edge 90 along the top edge of the main plate 80 which, as explained below, forms a track for the actuator 76.
The area including and surrounding the bottom-rear plate-to-housing screw holder 82 may be referred to as the pivot area 84 of the main plate 80 (and/or the frame 70). The area between the pivot area 84 and the plate-to-housing screw holder 82, and the area between the pivot area 84 and the bottom-front plate-to-housing screw holder 82, can be referred to as the direction and speed switch-interacting areas 86 and 88, respectively. As explained below, the actuator 76 is pivotally connected to the main plate 80 (and/or the frame 70) in the pivot area 84, the actuator 76 interacts with the direction switch 72 in the area 86, and the actuator 76 interacts with the speed switch 74 in the area 88.
The speed-switch-interacting area 88 of the main plate 80 (or an area just thereabove) includes an opening 92 and another opening 94 in front thereof. The opening 92 is aligned with the opening 62 in the housing 42 for receipt of the high-speed lockout screw 66. The storage opening 94 is aligned with the opening 64 in the housing 42 and likewise serves as a storage location for the screw 66 when a high-speed lockout is not required and/or desired.
The direction switch 72 comprises a casing 100 and a projecting toggle 102 pivotally connected to the casing 100 and movable about a pivot axis 104 between a front (first) position and a rear (second) position. The speed switch 74 comprises a casing 106 and a projecting toggle 108 pivotally connected to the casing 106 and movable about a pivot axis 110 between a front (first) position and a rear (second) position.
In the illustrated embodiment, the front position of the direction-switch toggle 102 is its forward-direction position and the rear position of the toggle 102 is its rear-direction position. Also, the front position of the speed-switch toggle 108 is its high-speed position and the rear position of the toggle 108 is its low-speed position. In
The casing 100 is secured to the main plate 80 so that the direction switch toggle 102 projects into the interacting area 86 and the casing 106 is secured to the main plate 80 so that the speed-switch toggle 108 projects into the interacting area 88. It may be noted for future reference that the pivot axes 104 and 110 are substantially parallel and perpendicular to the plane of the main plate 80. The switches 72/74 can each additionally include a wire harness 112/114 which electrically conveys the position of the toggle 102/108 to the appropriate circuitry (e.g., circuit 160, introduced below) of the drive assembly 16.
The actuator 76 can have a roughly mushroom-like shape with a stem portion 120 and a head portion 122 which share a central axis portion 124. The illustrated actuator 76 further includes a handle portion 126 which is coextensive with the central axis portion 124 and extends upward from the stem portion 120. The portions 120, 122, 124, and 126 are preferably integral with each other (e.g., molded as one piece) and the central axis portion 124 can be ribbed, as shown, for strength-imparting purposes.
As is best seen by referring briefly back to
The bottom end of the stem portion 120 is pivotally attached to the pivot area 84 of the main plate 80 so that the actuator 76 can be moved relative to the housing 40 and the frame 70. In the illustrated embodiment, this pivotal attachment is accomplished by the stem portion 120 having a sleeve 130 which receives the lower bottom plate-to-housing screw holder 82 of the main plate 80 in a bearing-like manner. The actuator 76 can thereby move relative to the frame 70 about a pivot axis 132 among a forward-high setting, a forward-low setting, and a reverse-low setting to place the drive assembly 16 in the forward-high condition, the forward-low condition and the reverse-low condition, respectively.
The actuator pivot axis 132 is substantially perpendicular with the main plate 80 and, in any event, is substantially parallel with the pivot axes 104 and 110 of the switches 72 and 74. Additionally or alternatively, the actuator 72 moves in a plane as it moves among the forward-high setting, the forward-low setting, and the reverse-low setting. This plane of movement is non-parallel with, and substantially perpendicular to, the pivot axes 104 and 110 of the switches 72 and 74.
As was alluded to above, and as explained in more detail below, front/rear movement of the actuator 76 results in movement of the toggles 102/108 between their front positions and their rear positions. The parallel arrangement of the pivot axes 104, 110 and 132 results in the force applied to move the actuator 76 being applied in the same parallel direction to the toggles 102/108 for movement thereof. This force-application pattern can provide a child driving the vehicle 10 with a gear-shifting-feel that accurately resembles that which is experienced in an adult-size vehicle.
Turning now to the head portion 122 of the actuator 76, it can include a flange 138 along its upper edge which, during pivotal movement of the actuator 76, slides along the track formed by the flange 90 on the upper edge of the frame plate 80. The head portion 122 is also the switch-interacting portion of the actuator 76 and, to this end, includes switch-interacting slots 140 and 142. The direction-switch-interacting slot 140 is formed in a rear region of the lower edge of the head portion 122 and includes a front (first) wall 144 and a rear (second) wall 146. The speed-switch-interacting slot 142 is formed in a front region of the lower edge of the head portion 122 and includes a front (first) wall 148 and a rear (second) wall 150. It may be noted for future reference that the outer slot walls 146 and 148 (i.e., the rear wall 146 of the slot 140 and the front wall 148 of the slot 142) are shorter than the inner slot walls 144 and 150 (i.e., the front wall 144 of the slot 140 and the rear wall 150 of the slot 142).
The head portion 122 includes a high-speed lockout slot 152 located above the speed-switch-interacting slot 142. This slot 150 receives the high-speed lockout screw 66 when it is inserted through the high-speed lockout opening 62 in the housing 42 and the high-speed lockout opening 92 in the main plate 80. Likewise, the high-speed lockout slot 152 will not interact with the high-speed lockout screw 66 when it is placed in the storage openings 64 and 94.

It may be noted that the circuit 160 electrically allows for the possibility of a setting whereat the drive assembly 16 drives the wheels 14 at a high speed in a reverse direction. However, the illustrated design of the shifter 40 precludes such a condition. Specifically, the direction-switch toggle 102 must be placed in its front position (i.e., its forward-direction position) prior to the speed-switch-interacting slot 142 engaging the speed switch toggle 108. Likewise, the speed-switch toggle 108 must be placed in its rear position (i.e., its low-speed position) prior to the direction-switch-interacting slot 140 engaging the direction switch toggle 102. Thus, the shifter 40 mechanically prevents a situation whereat the direction-switch toggle 102 is in its rear position (i.e., its rear-direction position) at the same time as the speed-switch toggle 108 is in its front position (i.e., its high-speed position).

The high-speed-lockout feature is utilized by inserting the high-speed lockout screw 66 in the opening 62 in the housing 42 and then through the opening 92 in the frame 70. In the illustrated embodiment, this insertion can be accomplished from outside of the housing 42 whereby disassembly of the shifter 40 is not necessary. In any event, this insertion of the high-speed lockout screw 66 results in it being positioned at the rear end of the high-speed lockout slot 152 when the actuator 76 is in its forward-low setting, thereby blocking frontward movement of the actuator 76 to its high-speed setting. (See
One may now appreciate that a shifter 40 is provided to shift the drive assembly 16 of a child's riding vehicle 10 among a forward-high condition (whereat it drives the wheels forward at a high speed), a forward-low condition (whereat it drives the wheels forward at a low speed), and a reverse-low condition (whereat it drives the wheels in reverse at a low speed). Although the invention has been shown and described with respect to certain preferred embodiments, it is evident that equivalent and obvious alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification.
