Building block
First Claim
1. A building block, comprising a first and a second square frame perpendicularly connected to each other at inner edges thereof, and a hypotenuse frame extended between outer edges of said first and said second frame;
- said first and second square frames and said hypotenuse frame respectively having an outer frame portion and a cross-shaped rib portion located within said outer frame portion;
said cross-shaped rib portion on each of said square and hypotenuse frames dividing a space enclosed in said frame into four equal divisions; and
said four equal divisions being four cavities on said first square frame, being two diagonally opposite connecting protrusions and two cavities diagonally located at two sides of said two connecting protrusions on said second square frame; and
being two diagonally opposite connecting protrusions and two rectangular cavities diagonally located at two sides of said two connecting protrusions on said hypotenuse frame.

Abstract
A building block includes two perpendicularly connected square frames, and a hypotenuse frame extended between outer edges of the two square frames. Each of the square and hypotenuse frames has an outer frame portion and an inner cross-shaped rib portion having a thickness twice as large as that of the outer frame portion. The cross-shaped rib portion divides a space enclosed in each frame into four equal divisions, which are four cavities on one of the two square frames; two diagonally opposite round connecting posts and two diagonally opposite cavities on the other square frame; and two diagonally opposite connecting protrusions and two diagonally opposite rectangular cavities on the hypotenuse frame, so that a plurality of the building blocks could be assembled together in different manners to form changeful shapes via engagement of the cavities with corresponding connecting posts or protrusions.
