Abstract
A wheel for use in a construction system of building bricks in the form of the letter "H". This system is based on an arbitrary standard dimension "a". The wheel has a rim and a hub and optionally a ring surrounding the rim. The wheel is provided with axially extending grooves. The specified dimensions make the wheel especially advantageous for use with the system.

A wheel for use in a construction system of building bricks in the form of the letter "H" which system is based on an arbitrary standard dimension "a";
- said wheel comprising:
- A. A rim having two opposing sides and a diameter of 12a/.pi., said rim having a plurality of axially extending and radially aligned grooves on each side of the rim, equally spaced around the circumference of the rim;
- each of said grooves having opposing sides spaced from each other by the distance "a";
- said rim having an axial cylindrical opening;
- and
- B. a hub rotatably mounted in the axial cylindrical opening of the rim;
- said hub having an axially disposed square opening having dimensions "a" by "a";
- wherein the wheel has a width 2a.
