US 4,236,344 A · Toy with spring-operated speed regulated motor mechanism

Abstract

A toy having a pivotable component in the form of a construction wheel loader having a shovel, the toy including a manually actuable handle cocking a spring coupled to a slidable member having a rack portion for operating the shovel. Movement of the slidable member during cocking of the handle simultaneously moves a coupler connected to a piston slidable axially within a stationary closed ended cylinder. The piston has a minute aperture in the face thereof with a larger aperture in the skirt thereof with the apertures being on opposite sides of the piston seal. A locking lever coacts with the coupler for retaining the parts in the powered position against the force of the spring. Manual release of the locking lever permits the spring to urge against the slidable member with the two apertures in the piston providing speed regulation during movement of the piston into the cylinder for moving the slidable member gradually.

Dependent claims

In a toy, the combination comprising:

a supporting structure;
a component attached to said structure for movement relative thereto;
handle means movably mounted on said supporting structure;
a member mounted for slidable movement within said structure, said member being operatively connected to said component to effect movement of the component;
spring means operatively interconnecting said handle means and said member for sliding said member in a first direction to a predetermined position in response to movement of said handle means;
means for retaining said member in said predetermined position against the force of said spring means whereby said spring means may be cocked;
and
speed regulating means operatively coupled to said member for controlling the rate of movement of said member in a direction opposite to said first direction upon release of said retaining means for controlling the speed of movement of said component.

In a toy construction vehicle, the combination comprising:

a supporting structure;
an arm assembly having one end thereof pivotally coupled to said supporting structure;
a shovel-shaped component pivotally coupled to the other end of said arm assembly;
a linkage pivotally coupled to said arm assembly and having one end thereof coupled to said shovel-shaped component for relative movement therebetween;
handle means moveably mounted on said supporting structure;
a member mounted for slidable movement within said structure, said member being operatively connected to the other end of said linkage for pivoting said linkage in response to movement of said member;
spring means operatively interconnecting said handle means and said member for sliding said member in a first direction to a predetermined position in response to movement of said handle means;
means for retaining said member in said predetermined position against the force of said spring means whereby said spring means may be cocked;
and
speed regulating means operatively coupled to said member for controlling the rate of movement of said member in a direction opposite to said first direction upon release of said retaining means for controlling the rate of pivoting of said linkage.
