In practice, it has been observed that children lack the dexterity and coordination to start in motion a toy vehicle that is exactly in straight-ahead path of movement.
A miniature-sized toy vehicle that is set in motion with a push along straight-ahead path of movement and which rides on a wheel bearing in depending relation from the vehicle chassis, the revolving mode of which wheel bearing contributes to an optimum length of travel, and wherein the vehicle chassis has a straight movement about the wheel bearing and during its travel will not turn aside and keep a proper position for travel along straight-ahead path of movement, to further increase the length of travel of the toy vehicle.
The description of the invention which follows, together with the accompanying drawings should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof within the ambit of the appended claims.
Shown is the drawings in a preferred width 17.4 mm, length of 35.6 mm, and height of 13.2 mm, is a miniature-size toy vehicle, generally designated 10, having a body 12 consisting of a wall 14 whose exterior surface simulates the appearance of a full-sized vehicle and an internal surface which bounds a compartment 16 for the positioning of a Speed Wheel bearing 18 which has a width of 0.8 mm flat surface on the wheel edge 19, 9.4 mm in diameter, 6 mm in thickness and two axles with 1 mm in diameter, with an operating mode of urging the toy vehicle 10, in response to a manual push or thrust 20 of a user 22, in a steady straight-ahead path of movement 24 and not going circular movement, the length of which, if of a maximum extent, contributes to the play value of the toy vehicle 10.
Appropriately attached, as by screws 31 or the like, as a closure for the Speed Wheel bearing positioning compartment 16 is an aptly referred-to Roller Wheel bearing means in the specific form of a plate 32 which contributes to the low-friction revolving 34 of the Speed Wheel 18 and, which plate 32 to this end has a pair of knobs 36 which has a gap 4 mm in length that support a Speed Wheel 18 within the oval opening 38 of a selected size 40 which is slightly oversized with respect to the size 42 of Speed Wheel 18 allows Speed Wheel 18 moving up and down and so that reduces friction with the plate 32 and provides higher speed in revolving 34 of Speed Wheel 18.
The body 12 is held in a horizontal position relative to the riding surface 48 by four simulated vehicle wheels 50 at opposite ends of axles 52 appropriately attached to internal walls 54 depending from the body 12, but otherwise the wheels 50 are not functional in contributing to the length of travel of toy vehicle 10. What is functional to the length of travel of the toy vehicle 10 is the Speed Wheel 18 in a revolving mode 34 in contact, as at 47, with the knobs 36 integral to the plate 32.
While the toy vehicle herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the detail of construction or design herein shown other than as defined in the appended claims.
