(1) Technical Field
The present invention relates to the field of toy vehicles and, more specifically, to a spring-powered toy vehicle that uses a spring to propel the toy vehicle forward and also includes a launcher to initiate its propulsion.
(2) Background
Toy vehicles are numerous and have existed for many years. Self-propelled toy vehicles have been developed that contain a mechanism for driving the toy vehicle forward without requiring manual force. Many self-propelled toy vehicles have complex mechanisms and propulsion devices that lack durability or require expensive, complex electronics. A simple, inexpensive spring-powered toy vehicle with few moving parts that is durable and is fun for children to play with would be welcomed by children and the toy industry.
Thus, a continuing need exists for a spring-powered toy vehicle that uses a simple spring to propel the toy vehicle forward.
The present invention relates to a toy vehicle that is spring-powered. The spring-powered toy vehicle (for brevity called herein the “vehicle” or the “toy vehicle”) has a front body portion with at least one wheel rotatably attached thereto and a separable rear body portion that also has at least one wheel rotatably attached thereto. A spring that connects with the front body portion and the rear body portion provides a propulsive force, such that when the rear body portion is pulled away from the front body portion, potential energy is created. When the rear body portion is released, the potential energy is converted to kinetic energy and the spring pulls the rear body portion into the front body portion. When the rear body portion impacts the front body portion, the kinetic energy is transferred to the front body portion propelling the entire vehicle forward quite rapidly. In an additional aspect, the spring is detachable and in another aspect the spring is interchangeable with springs of varying strengths. The vehicles have a right and left side.
A connecting rod and in one aspect a cylinder that contains the connecting rod, provides structural support for the spring, and parallel vehicle guides in another aspect prevent the rear movable body portion from pulling away in a non-axial direction, so that the toy vehicle will only be propelled in a straight line direction while twisting force on the spring is prevented. The vehicle guides are also designed to allow the front and rear body portions to have a maximum separation when the rear is pulled away from the front while at the same time allowing separation of the two portions. In another embodiment there are two vehicle guides, one on the left side of the vehicle and one on the right side of the vehicle and the two vehicle guides are comprised of tongue and groove assemblies.
In another aspect the vehicle can be an auto, a truck, a motorcycle, a plane or a construction vehicle. Non-limiting examples of construction vehicles include a wheeled bull-dozer and a road-grader. Also provided for in this invention is a plurality of different versions of like vehicles. The rear body portion has a posterior and anterior end that can be detached from the front body portion, which also has a posterior and anterior end. The front and rear body portions from different versions of like vehicles are interchangeable. In another aspect, the front body portion has a hinged flip top at its anterior end, allowing the top to flip up, permitting easy access to the spring inside. This invention also teaches a rear body portion with a front segment, a back segment and the front segment has a top. The front body portion in this version is detachably attached on top of the front segment of the rear body section. The front segment of the rear body portion comprises at least one wheel and the back segment also comprises at least one wheel and a spring.
In a further aspect of the present invention, the spring-powered toy vehicle spring further comprises a spring assembly. The spring assembly comprises a connection rod sliding within a cylinder, surrounded by the spring. Both the cylinder and the connection rod contain end caps with a raised cylindrical band to which the spring attaches near each end of the assembly. Each end cap fits into a receptacle, one at the posterior end of the front body portion and the other into the anterior end of the rear body portion. One additional version of this invention has the raised cylindrical section on the cylinder at the cylinder end of the spring assembly, thus mandating only one end cap.
The connection rod and cylinder force the spring to expand in an axial direction along the direction of travel of the spring-powered toy vehicle. In another aspect of the present invention, the spring assembly is removable. In a further aspect of the present invention, the spring assembly is made in a plurality of strengths and colors and each is interchangeable for any of the spring powered toy vehicles.
In still another aspect of the present invention, the rear body portion further includes a handle for a user to grasp while pulling the rear body portion away from the front body portion. The front body portion has a top and on the top of the front body portion is a thumb notch. A user places a thumb on the thumb notch and then with the other hand of the user, the handle is grasped and the rear body portion is pulled away from the front body portion.
A launcher version of the vehicle uses a launcher to launch the vehicle and necessitates that the handle comprise a peg oriented perpendicular to the direction of travel of the vehicle. On this version, a notch is included on the bottom of the vehicle. The launcher provides a stable platform for launching the spring-powered toy vehicles. The launcher, having a launching end, a plunger end, and a closed interior. The launcher is comprised of a platform and ramp that includes an underside (contained in the closed interior of the launcher and is not visible to an observer) encased in a housing that has an axially oriented, spring-loaded plunger at the plunger end that is permitted to travel when it is pulled. Once released, the spring action returns it to its resting position. At the launching end of the ramp is a peg and slot assembly with an anterior and posterior end, the peg of the peg and slot assembly fits into the notch in the underside of the vehicle. The travel of the peg in the peg and slot assembly is less than the travel of the plunger. The peg travels with the vehicle when attached and moves as the plunger is pulled. Once the vehicle is released the peg returns to the anterior end of its slot. At the launching end of the plunger is a spring-loaded, hinged and pivoting u-shaped retaining receptacle that in its resting state is not allowed to pivot. The retaining receptacle is mounted on a rod that extends to the underside of the ramp (and hidden from view of an observer). Attached to the rod, on the underside of the ramp, is a rectangular plate that travels on the underside of the ramp with the plunger (as the plunger is pulled and returns) and the retaining receptacle.
The vehicle is set into the launcher so that its notch is secured on the peg of the peg and slot assembly and the peg of the handle is secured in the retaining receptacle. When the plunger is pulled, the peg and slot allows limited travel of the front body portion until that limit is reached. The plunger travels more than the peg and slot, causing the spring in the vehicle to expand and creating potential energy. Once the peg of the peg and slot reaches its maximum travel point, and the vehicle becomes stretched to its limit, the rectangular plate beneath the retaining receptacle rides up a pair of humps in the underside of the ramp. This causes the rectangular plate to tilt up which, in turn, causes the retaining receptacle to pivot down, thus releasing the vehicle. The potential energy of the spring loaded peg and slot, the spring loaded plunger and the spring of the vehicle are combined and converted into kinetic energy causing the vehicle to leap from the launcher at a furious pace.
In another aspect, the launcher has a base on its bottom and a tab is located at the launching end of the base. The tab is designed to fit into a slot on a track designed to accommodate the wheels of the vehicles. Once launched, the vehicles move on the track until the kinetic energy that drives them is spent.
This invention also teaches a method for forming a spring-powered toy vehicle that comprises attaching at least one rotatable wheel to a front body portion and at least one rotatable wheel to a rear body portion. The method also includes an act of removably attaching the front and rear body portions allowing the body sections to touch and achieve a limited separation point. Additionally, the method includes an act of placing a spring between each of the front and rear body portions.
Finally, as can be appreciated by one skilled in the art, the present invention further comprises a plurality of acts of forming and attaching the various parts of the toy vehicle and launcher described herein to arrive at the present invention.
