Abstract
A collapsible toy building block with strong board members. Base board (12) and roof board (10) interconnect loosely with frame boards (24)(24A). Frame boards set loosely in channel (26) that is formed by, short in length, projecting spacers (18) that run parallel to flanges (14),(16) that are along the front and back ends of base (12) and roof (10). A building block of this construction can be combined with other identical building blocks or a variety of other building blocks, that have the same widths, to build toy buildings of many different configurations. The loosely fitting members, of a building block of this type, permit a building block or toy building constructed of building blocks to be knocked down flat by an outside force.
Claims2
A toy construction block comprising:
- a base board, roof board and four frame boards;
- the top of the base board and the bottom of the roof board each having parallel flanges and spacers defining a channel about the board periphery;
- the four frame boards loosely fitting between the channels so that a six sided building block can be built;
- the top of the roof and the bottom of the base each having a set of two parallel fillets, one set of fillets being spaced wider than the other set of fillets so that another said building block can be stacked with the building block wherein the sets of fillets straddle each other;
- and
- the construction block being capable of being knocked down flat by an outside force.
