发明名称 Recreational kit for constructing objects
摘要 This invention discloses a kit for assembling light, airy, toy-like designs from blocks and solid sticks made of the same material throughout. The blocks preferably have tapered holes adapted to receive the sticks' ends therein. The holes and the sticks are adapted to compressively engage with one another upon insertion of selected ends of the sticks in the holes, thereby providing a secure grip by each hole's wall upon the end of the associated stick, locking it into the hole.
