A molded product is made comprising a low-density product having an impermeable surface. The impermeable surface integral with the low density interior is suitable for receiving various types of brightly colored finishes. It is also contemplated that a non-porous plastic film may be molded in place on the surface of the molded product.

Molded product and method of manufacture

Thermosetting polymer compositions for forming molded products having a soft, resiliently deformable skin are provided. The polymer resin compositions include polyvinylchloride, phthalic acid ester, a heat stabilizing agent and a heat resistance agent and have physical properties that resemble latex-containing compositions.

A method of molding, from porous material, a low-density product having an impermeable surface. A mold is provided, which has a cavity, the outline of which defines the outline of the product. The starting material is a flat sheet of plastic foam. The first step of the process, in some cases, is a pre-heating procedure, which softens the material. Then, from this sheet there is stamped a blank having substantially the outline of the desired product, which is then inserted into the mold cavity. The mold is then heated with the blank therein to form the blank permanently into the desired product, after which the mold is quenched in cold water with the product still inside. The product is subsequently removed from the mold and frozen. The result of this molding method is a low-density product having an impermeable surface integral with the foam interior which is suitable for receiving various types of brightly colored finished. It is also contemplated that a non-porous plastic film may be molded in place on the surface of the product.

A toy vehicle which upon frontal impact with an obstacle simulates in its appearance the consequences of a car crash. The vehicle has a hollow body mounted on a chassis, which body includes a front hood section provided with a front bumper, an intermediate cab section having a hinged door on either side, and a rear section. The cab and rear sections are secured to the chassis, whereas the front section, which is formed of resilient material, is free of the chassis. The front wheels rotate on short axles whose bearings are pivoted on the chassis so that these wheels in their normal state are parallel to the chassis, and in the crash state are angled with respect thereto, as a result of which the wheels are skewed. Slidable on the chassis is a slide whose front end is secured to the bumper, the slide being maintained by a spring-biased detent in a forward position and being urged by a spring to a retracted position. The front wheel bearings and the hinged doors are operatively linked to the slide so that in its forward position, the front hood section is undeformed, the doors are closed and the front wheels are in their normal state. When, however, the vehicle makes frontal impact, the shock thereof releases the detent, thereby freeing the slide to cause it to be shifted to its retracted position, in the course of which the wheels are caused to assume their skewed state, the doors are outflung and the front hood section is deformed to simulate a crash.

A toy vehicle has a seat with a simulated seat belt in the form of two semi-circular parts which are able to rotate between an opened and closed position, the closed position simulating fastened seat belts. A power release push button is centrally positioned on the vehicle so that it does not exert any unbalanced force on the vehicle when it is pressed. When the seat belt is opened, the push button is captured in a raised position so that the vehicle cannot run. When the seat belt is closed, the capture is released from the push button so that is can be pushed. Thereafter, the push button is pushed, the power is released, and the toy vehicle is propelled.

Toy vehicle activated by moving body part

An inertia motor especially--but not exclusively--for a toy vehicle. A rear wheel axle extends through the housing and has a drive gear mounted thereon to turn unitarily therewith. A flywheel is rotatably mounted on the housing for spinning to store or to payout energy. First and second gear trains extend between the drive gear and flywheel. A movable control lever carries first and second movable gears, one of the movable gears being an idler mounted on and movable with a shaft which passes through a pair of oppositely disposed arcuate slots, the other movable gears being mounted on a shaft journaled in the lever arm. The arcuate slots are located so that the idler gear meshes with one of the gear trains when the lever arm is in one of its two positions. The teeth on the meshing gears dynamically pull the shaft to one end of the arcuate slots and into the one gear train when the drive gear is driving and pushing the shaft to the other end of the arcuate slots to eject the idler from the one gear train when the flywheel is driving. The journals for the shaft of the other movable gear are located on the lever arm so that the other movable gear meshes with the other of the gear trains when the lever arm is in the other of its two positions. The arcuate slots are part of molded plastic parts which may be made with the precision of the mold, thereby improving performance and reducing wear from poor tolerances used heretofore.

Inertia motors for toy vehicles

A toy vehicle has a gear box containing a clock spring which is wound by pushing the vehicle backward. A two part toggle-linkage system connects the gear box to the frame. When the clock spring is wound, the resulting spring bias urges the toggle-linkage system to one over center position which locks the gear box in order to preserve the energy stored in the wound spring. When the toggle-linkage system is pressed near its center, it moves over center to another position, which unlocks the gear box and releases the energy stored in the wound spring in order to propel the vehicle. When the vehicle is next moved backward, the toggle-linkage returns to the locked position which once again locks the gear box.
