Abstract: A jet propulsion construction toy assembly includes a container mounted on a movable brick assembly. A launching unit includes a launching seat permitting extension of a nozzle of the container thereinto and having an inlet. When the nozzle extends into the launching seat, an actuator mounted movably in said launching seat is operable to engage the nozzle such that said container is filled with fluid including air and liquid and pumped out of a barrel by a pump through first and second conduits, the inlet and the nozzle. Thereafter, when the nozzle is released from the launching seat due to disengagement between the nozzle and the actuator, jet of the fluid from the container through the nozzle forms a propulsion force to drive movement of a combination of the brick assembly and the container away from the launching unit.

Abstract: An inexpensive air valve-connector can enable the construction of inflatable structures having multiple inflatable components. In particular, an inflatable component can be connected to an inflated structure and inflate without deflating the structure. Specifically, positive air pressure generated by an air blower, i.e. a fan, is used to inflate a structure composed of one or more blocks that self-inflate upon connection to inflated blocks. The air valve-connector can be embodied in a low-cost building block toy. The air valve-connector can also be used to create other inflatable structures, such as decorations and signage. The air valve-connector comprises two light-weight connectors that can exist on opposite sides of the same block. The valve includes a compressible material, such as foam, that is actuated to open the valve. When two blocks are connected via the air valve, air is transferred from a first block to a second block.
