...... Continuing the LEGO story from the previous post
In the last three decades of the 20th century, Lego expanded into new areas of toy manufacturing and sales. In 1971, Lego began to introduce furniture and doll houses, targeting girls. In 1972, Lego added boats with floating hulls.
During the same period, Kjeld Kirk Kristiansen, the son of Godfred Kirk Christiansen, joined the management after obtaining business degrees in Switzerland and Denmark. One of Kjeld's first achievements in the company was the foundation of the manufacturing facility and the R&D department responsible for keeping the company's manufacturing methods up to date. In 1974, characters with foldable weapons appeared in the "Lego Family" series, which later became the largest seller at the time. The following year, an early version of the "miniature" Lego miniature was launched, but it was out of fashion and there was no expression on its head. The company opened its first North American Lego production plant in Enfield, Connecticut, in the same year.
The "Expert Series" kit was introduced in 1975 to accommodate older and experienced LEGO brick manufacturers, followed by the "Expert Builder" kit in 1977. The technology kit has moving parts such as gears, differentials, cogwheels, levers, axles and universal joints, and allows the construction of realistic models such as cars, functional rack and pinion steering, and realistic engine movements. In 1978, the Lego toy "minifigure" was added. These little Lego guys have ridiculous arms and legs, and they smile. The figure is used in a variety of Lego toys, allowing the construction of towns with smiling little Lego citizens. Lego also expanded to space, launching Lego space installations with astronaut minifigures, rockets, lunar rover and spaceships, and themed castles in medieval areas.
In 1979, Lego launched the Scala series, which featured selling jewelry elements to young girls. That year Kjeld Kirk Kristiansen also served as Lego president.
Since the 1960s, educators have regarded the productive potential of Lego bricks as a valuable asset in helping children develop creativity and problem-solving skills. For various reasons, teachers have been using Lego bricks in the classroom. The Lego Group established the Educational Products Department in 1980 (eventually renamed Lego Dacta in 1989) to expand the educational possibilities of its toys. A packaging and assembly plant was opened in Switzerland, followed by a plant for the production of Lego tires in Jutland, Denmark.
