Roller Skate

Introduction

recreational and competitive sport in which the participants use special shoes fitted with small wheels to move about on rinks or paved surfaces. Roller-skating sports include speed skating, hockey, figure skating, and dancing competitions similar to the ice-skating sports, as well as the vertical and street-style competitions common to so-called extreme sports.

 

Development of the roller skate

The invention of roller skates has been traditionally credited to a Belgian, Joseph Merlin, in the 1760s, although there are many reports of wheels attached to ice skates and shoes in the early years of that century. Early models were derived from the ice skate and typically had an “in-line” arrangement of wheels (the wheels formed a single straight line along the bottom of the skate). In 1819 M. Petibled of Paris received the first patent for a roller skate. Like previous models, Petibled's skate had an in-line wheel arrangement, using three wooden or metal wheels. The wheels were connected to a wooden block that in turn could be strapped to a boot. These early roller skates enjoyed limited popularity. The ride was rough, and stopping and turning were nearly impossible.
The first practical roller skate was designed in 1863 by James Plimpton of Medford, Massachusetts, who broke from the in-line construction and used two parallel pairs of wheels, one set near the heel of the boot and the other near the front. He attached the wheel pairs to the boot using springy carriages known as trucks. This construction was first known as the “rocking” skate (and is now known as a “quad”) because it allowed the skater to easily shift on the skates in order to smoothly navigate turns and perform other maneuvers. Thereafter the first great recreational roller-skating craze swept the United States and western Europe, where rinks were built in both small towns and large cities. At the turn of the 20th century, rinks constructed in the Chicago Coliseum and New York City's Madison Square Garden attracted thousands of customers on their opening nights. The quad style of skate became the most popular skate for the next 80 years.
Plimpton's quad skates were soon followed by other technological improvements. In the 1880s ball bearings were added to the wheel construction, allowing for a smoother ride. Toe stops for braking were introduced as early as the 1850s; however, the large rubber toe stop for quad skates was not widely used until the 1950s. Heel stops were introduced with some of the earliest roller skates but were perfected only with the re-emergence of in-line skates in the 1980s. In the 1960s the wooden or metal wheels traditionally used in skates gave way to lightweight polyurethane plastic wheels that gripped the riding surface better.
In the 1980s roller-skating enjoyed renewed popularity with the creation of a new generation of in-line roller skates by hockey-playing brothers Scott and Brennan Olson, the founders of Rollerblade, Inc. They developed in-line skates with four wheels that extended the full length of the boot, giving the skater greater maneuverability (compared with previous in-line skates) and much more speed. The company also introduced lightweight plastics and other materials to the boot construction, as well as buckles that allowed for easy adjustments to the fit and comfort of the skate.
