Abstract
Abstract A toy spray painting system which includes a hand-held manually powered spray gun along with an easel for holding a substrate such as paper to receive a paint spray from the spray gun. The hand-held spray gun includes a frame having a pistol-grip handle with a trigger for one hand operation. Squeezing of the trigger will operate a member to issue air under pressure; the member could adopt the form of, for example, an expandable and contractable bellows which is operable by squeezing the trigger. Upon squeezing of the trigger, air under pressure is ejected through an orifice in a spray head of the spray gun to create an issued air stream. The issued air stream passes over a paint outlet defined by an opening in the upper end of an upright tube which extends down into a container of liquid paint. The paint container is also held by the frame. The spray gun operates in the manner of a liquid ejector so that a portion of the liquid paint is atomized and entrained in and carried by the stream to the substrate. Due to the design of the spray gun, it can be held and operated in one hand merely by squeezing the trigger. An adjustable mechanism on the spray gun permits adjustment of the height of the paint outlet relative to the height of the orifice in order to adjust the amount of paint entrained in the air stream. Stencils may be provided for face-wise disposition over the paint receiving surface of the substrate to create various patterns.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
352 words
A children's toy manually powered paint spraying system for spraying a paint composition onto a substrate, said spraying system comprising: a. frame means, b. a container on said frame means for receiving a liquid paint composition therein, and said container having a generally upright tube which extends down into said container and defines a paint outlet at its upper end, c. means on said frame means defining a contractible and expandible air chamber capable of expelling air upon reduction in its size and capable of receiving air upon increase in its size, d. manually powered means on said frame means for causing reduction and increase in the size of said air chamber, e. means defining an air orifice in communication with said air chamber and capable of generating an exit stream of air under pressure upon reduction of said air chamber size, said paint outlet being located in proximity to said air orifice to cause emission of a portion of the paint composition in said container and to atomize said composition in a moving stream of air passing through said orifice to create a spray of the paint composition, f. adjustment means on said frame means for regulating the distance between said air orifice and said paint outlet and g. an easel construction for holding a substrate to receive the sprayed paint composition, said easel construction comprising: a. an easel frame having a recess to receive a substrate, b. a stencil capable of being disposed in said recess over said substrate and having open portions to permit said paint composition to be received on said substrate and closed portions to block said paint composition, c. a retaining frame hingedly mounted on said easel frame to retain said substrate and said stencil in said recess, said retaining frame being shiftable from an open position to a closed position where said substrate and stencil are held in said recess, d. locking means for removably locking said retaining frame to said stencil frame, and e. a flange means extending from said retaining frame and into said recess to retain and hold said stencil and substrate.
