Baby transport

William Kent developed an early stroller in 1733.[8] In 1733, the Duke of Devonshire asked Kent to build a means of transport that would carry his children. Kent obliged by constructing a shell shaped basket on wheels that the children could sit in. This was richly decorated and meant to be pulled by a goat or small pony. Benjamin Potter Crandall sold baby carriages in the US in the 1830s which have been described as the "first baby carriages manufactured in the US"[9] Another early development was F.A. Whitney Carriage Company. His son, Jesse Armour Crandall was issued a number of patents for improvements and additions to the standard models. These included adding a brake to carriages, a model which folded, designs for parasols and an umbrella hanger. By 1840, the baby carriage became extremely popular. Queen Victoria bought three carriages from Hitchings Baby Store.

The carriages of those days were built of wood or wicker and held together by expensive brass joints. These sometimes became heavily ornamented works of art. Models were also named after royalty: Princess and Duchess being popular names, as well as Balmoral and Windsor.

In June 1889, an African American man named William H. Richardson patented his idea of the first reversible stroller. The bassinet was designed so it could face out or in towards the parent. He also made structural changes to the carriage. Until then the axle did not allow each wheel to move separately. Richardson's design allowed this, which increased maneuverability of the carriages. As the 1920s began, prams were now available to all families and were becoming safer, with larger wheels, brakes, deeper prams, and lower, sturdier frames.

In 1965, Owen Maclaren, an aeronautical engineer, worked on complaints his daughter made about travelling from England to America with her heavy pram. Using his knowledge of aeroplanes, Maclaren designed a stroller with an aluminium frame and created the first true umbrella stroller. He then went on to found Maclaren, which manufactured and sold his new design. The design took off and soon "strollers" were easier to transport and used everywhere.

In the 1970s, however, the trend was more towards a more basic version, not fully sprung, and with a detachable body known as a "carrycot".[notes 1] Now, prams are very rarely used, being large and expensive when compared with "buggies" (see below). One of the longer lived and better known brands in the UK is Silver Cross, first manufactured in Hunslet, Leeds, in 1877, and later Guiseley from 1936 until 2002 when the factory closed. Silver Cross was then bought by the toy company David Halsall and Sons who relocated the head office to Skipton and expanded into a range of new, modern baby products including pushchairs and "travel systems". They continue to sell the traditional Silver Cross coach prams which are manufactured at a factory in Bingley in Yorkshire.

Since the 1980s, the stroller industry has developed with new features, safer construction and more accessories.

Larger and heavier prams, or perambulators, had been used since their introduction in the Victorian era; prams were also used for infants, often sitting up. The term carrycot became more common in the UK after the introduction of lighter units with detachable baby carriers in the 1970s.

As they developed through the years suspension was added, making the ride smoother for both the baby and the person pushing it.

The word pram is etymologically a shortening of its now less common synonym perambulator.[10][11]

A child being pushed in a stroller

'Strollers' or 'pushchairs/buggies' (British English), are used for small children up to about three years old in a sitting position facing forward.

"Pushchair" was the popularly used term in the UK between its invention and the early 1980s, when a more compact design known as a "buggy" became the trend, popularised by the conveniently collapsible aluminium-framed Maclaren buggy designed and patented by the British aeronautical designer Owen Maclaren in 1965. "Buggy" is the usual term in the UK (sometimes "pushchair"); in American English, buggy usually refers to a four-wheeled vehicle known as a quad or quad bike in the UK. "Stroller" is the usual term in the USA. Newer versions can be configured to carry a baby lying down like a low pram and then be reconfigured to carry the child in the forward-facing position.

A variety of twin pushchairs are manufactured, some designed for babies of a similar age (such as twins) and some for those with a small age gap. Triple pushchairs are a fairly recent addition, due to the number of multiple births being on the increase. Safety guidelines for standard pushchairs apply. Most triple buggies have a weight limit of 50 kg and recommended use for children up to the age of 4 years.

A travel system is typically a set consisting of a chassis with a detachable baby seat and/or carrycot. Thus a travel system can be switched between a pushchair and a pram. Another benefit of a travel system is that the detached chassis (generally an umbrella closing chassis) when folded will usually be smaller than other types, to transport it in a car trunk or boot. Also, the baby seat will snap into a base meant to stay in an automobile, becoming a car seat. This allows undisturbed movement of the baby into or out of a car and a reduced chance of waking a sleeping baby.

Another modern design showcases a stroller that includes the possibility for the lower body to be elongated, thereby transforming the stroller into a kick scooter. Steering occurs by leaning towards either side. Depending on the model, it can be equipped with a foot- and/or handbrake. Speeds up to 15 km/h (10 mph) can be reached. The first stroller of this kind was the so-called "Roller Buggy", developed by industrial designer Valentin Vodev in 2005. In 2012 the manufacturer Quinny became interested in the concept and teamed up with a Belgian studio to design another model.

The modern infant car seat is a relative latecomer. It is used to carry a child within a car. Such car seats are required by law in many countries to safely transport young children.

In contemporary culture with four-figure systems or sleek jogging strollers common in some circles, strollers often serve as not only an infant transport device but also a highly visible symbol of everything from class to parenting philosophy.[12]
