Lego

Lego Group is a Danish company producing games with a range of products, the most popular being based on building blocks to assemble. It was the fifth worldwide top toy manufacturer in 2009. The company name was created by Ole Kirk Christiansen in 1932 from the Danish leg godt, meaning "play well". In Latin, Lego may mean "I read, " but it seems that this was know by Christiansen when he chose the name.

Dimensions

Lego bricks are a set of modular components. As a result, their dimensions are multiples of a base value, called module and component unit Lego, which applies in this case 1 / 8 inch (or 3.175 mm).

If we consider the most common brick, 2×4 studs, it is off 5 / 8 inch (15.875 mm) long, 10 / 8 (31.75mm) high and 3 / 8 (pads not included) three times the height of a plate. A plot radius is 2.38125 mm, more space between two studs is 1 / 8 inch, allowing you to slip a plate. Thus by superimposing 4 plates and a 2×2 tile, one obtains a cubic 5 / 8 side. Most competing products are offered in the same size, compatibility which makes them more attractive to consumers.

Origins

The first bricks, in 1949, were relatively simple: an empty shell with studs on top. There are also two side slits to confer sufficient elasticity to the brick assembly. The patent on January 28, 1958 for the current model, especially with the cylindrical drum disposed inside the shell from the blocks with staggered: for example, the number of contacts between two superimposed elements is increased, and ensures good performance bricks. Later, to the bricks of at least 2×2, the thickness of the shell is reduced and compensated by small veins. Finally, a center rib ensures the good performance of the walls, and limits the mold shrinkage.
