Wheelchair Tennis Players At The 2016 Summer Paralympics
A wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability. These can include spinal cord injuries ( paraplegia, hemiplegia, and quadriplegia), cerebral palsy, brain injury, osteogenesis imperfecta, motor neurone disease, multiple sclerosis, muscular dystrophy, spina bifida, and more. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand ("self-propelled"), by an attendant pushing from the rear using the handle(s ...

A Coffee And Black Wheelchair At Yuen Long
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Bath Chair
A bath chair—or Bath chair—was a rolling chaise or light carriage for one person with a folding hood, which could be open or closed. Used especially by disabled persons, it was mounted on three or four wheels and drawn or pushed by hand. It is so named from its origin in Bath, England. If required, the chair could also be mounted on four wheels and drawn by a horse, donkey or small pony with the usual turning arrangement. These animal-drawn versions were the forerunners of the invalid carriage. James Heath, of Bath, who flourished before the middle of the 18th century, was the inventor of the bath,chair. where bathing in the Roman Baths or visiting the nearby Pump Room was popular amongst sick visitors. Later versions were a type of wheelchair which is pushed by an attendant rather than pulled by an animal. In the 19th century they were often seen at spa resorts such as Buxton and Tunbridge Wells. Some versions incorporated a steering device that could be operated by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting ...

Paraplegia
Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek () "half-stricken". It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal. The area of the spinal canal that is affected in paraplegia is either the thoracic, lumbar, or sacral regions. If four limbs are affected by paralysis, tetraplegia or quadriplegia is the correct term. If only one limb is affected, the correct term is monoplegia. Spastic paraplegia is a form of paraplegia defined by spasticity of the affected muscles, rather than flaccid paralysis. The American Spinal Injury Association classifies spinal cord injury severity in the following manner. ASIA A is the complete loss of sensory function and motor skills below the injury. ASIA B is having some sensory function below the injury, but no motor function. In ASIA C, there is some motor function below the level of ...

Stephan Farffler
Stephan Farffler (1633 – October 24, 1689), sometimes spelled Stephan Farfler, was a German watchmaker of the seventeenth century whose invention of a manumotive carriage in 1655 is widely considered to have been the first self-propelled wheelchair. The three-wheeled device is also believed to have been a precursor to the modern-day tricycle and bicycle. Farffler, who was either a paraplegic or an amputee, also created a device for turning an hourglass at regular intervals and added chimes to the clocktower of Altdorf bei Nürnberg. the German WiKi says: either paraplegic as a result of an accident when aged three years; others describe him as a human with crippled legs Fabian Zilliken: ''Die Evolution des Fahrrads - Von der Laufmaschine zum "Custom(izing)" Artefakt'', 2012S. 10/ref> („verkrüppelten“ - which could also mean disfigured or malformed and this might, for onlookers, be an accurate description when, as said, the accident happened at a very young age which woul ...

He was '' jure uxoris'' King of England and Ireland from his marriage to Queen Mary I in 1554 until her death in 1558. He was also Duke of Milan from 1540.

Frieze
In architecture, the frieze is the wide central section part of an entablature and may be plain in the Ionic or Doric order, or decorated with bas-reliefs. Paterae are also usually used to decorate friezes. Even when neither columns nor pilasters are expressed, on an astylar wall it lies upon the architrave ("main beam") and is capped by the moldings of the cornice. A frieze can be found on many Greek and Roman buildings, the Parthenon Frieze being the most famous, and perhaps the most elaborate. This style is typical for the Persians. In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long stretch of painted, sculpted or even calligraphic decoration in such a position, normally above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made of may be plasterwork, carved wood or other decorative medium. ...
