Pogo Stick
A pogo stick is a vehicle for jumping off the ground in a standing position—through the aid of a spring, or new high performance technologies—often used as a toy, exercise equipment or extreme sports instrument. It led to an extreme sport named extreme pogo or "Xpogo". It consists of a pole with a handle at the top and footrests near the bottom, and a spring located somewhere along the pole. The spring joins two sections of the pole, which extends below the footpads. The jumper places their feet on the footpads while balancing on the pole, then jumps up or down with a bending action of the knees to add or subtract energy in the spring. When the spring is at full compression or extension, the jumper is lifted by the recoil of the spring, being launched several inches or feet into the air. This process is repeated to maintain a periodic bounce. The pogo stick can be steered by shifting one's weight off the centerline of the spring in the desired horizontal direction thus p ...

Flybar
:''Flybar may also refer to an element of the helicopter rotor.'' The Flybar is a modification of the traditional pogo stick design which allows riders to propel themselves up to a world record 8 feet 6 inches into the air according to the Flybar's website. Developed in a collaborative effort between SBI Enterprises, Bruce Middleton and Andy Macdonald, it utilizes in place of the usual steel spring in a regular pogo stick 12 elastic bands used for propulsion, also known as thrusters. It weighs 20 pounds (9 kilograms) and is capable of producing up to 1,200 pounds-force (5,300 newtons) of thrust. The Flybar comes in another model, the Flybar 800, which is intended for lighter people.

Powerbocking
Jumping stilts, bounce stilts or spring stilts are special stilts that allow the user to run, jump and perform various acrobatics. Spring stilts using fiberglass leaf springs were patented in the United States in 2004 under the trademark "PowerSkip", marketed for recreational and extreme sports use. Spring stilts are often mostly made of aluminium. Using these stilts is also called "bocking" or "powerbocking", derived from ''Alexander Böck'', the stilts' inventor. Powerbocking The act of "bocking" or "powerbocking" includes jumping, running, and performing acrobatics with elastic-like Spring (device), spring-loaded stilts. They can be used to jump great distances and allow the user to bounce over people and cars and to perform backflips. For some, it is an extreme sport; for others, it is a form of exercise, artistic expression and a form of entertainment. The stilts are often referred to generically as bocks or powerbocks; as power stilts, jumping stilts, bounce stilts or sp ...

Pogo Pin
A pogo pin or spring-loaded pin is a type of electrical connector mechanism with spring plungers that is used in many modern electronic applications and in the electronics testing industry. They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration. The name ''pogo pin'' comes from the pin's resemblance to a pogo stickthe integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection. This helical spring makes pogo pins unique, since most other types of pin mechanisms use a cantilever spring or expansion sleeve. A complete connection path requires a mating receptacle for the pin to engage, which is termed a ''target'' or ''land''. A pogo target consists of a flat or concave metal surface, which unlike the pins, has no movin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pogo Oscillation
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by Rocket engine#Combustion instabilities, combustion instability. The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle. The name is a metaphor comparing the Flight control surfaces#Longitudinal axis, longitudinal vibration to the bouncing of a pogo stick. Pogo oscillation places stress on the frame of the vehicle, which in severe cases can be dangerous. Origin NASA Associate Administrator for Manned Space Flight George Mueller (NASA), George Mueller explained Apollo 6's pogo oscillation to a congressional hearing: In general, pogo oscillation occurs when a surge in combustion chamber pressure increases back pressure against the fuel coming into the engine. This reduces fuel flow and thus chamber pressure. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pogo (dance)
The pogo is a dance in which the dancers jump up and down, while either remaining on the spot or moving around; the dance takes its name from its resemblance to the use of a pogo stick, especially in a common version of the dance, where one keeps one's torso stiff, one's arms rigid, and one's legs close together. Pogo dancing is most associated with punk rock, and is a precursor to moshing. Style The basic steps allow for a variety of interpretations, some of which might appear quite violent. Pogo dancers have their choice of: *Keeping their torsos rigid or thrashing them about; *Holding their arms stiffly at their sides or flailing them; *Keeping their legs together or kicking about; or *Jumping straight up and down, jumping in any direction, or spinning in the air. History In ''The Filth and the Fury'', Sex Pistols bassist Sid Vicious claimed that he invented the pogo sometime around 1976 at punk shows in the early days of London's punk scene. Vicious supposedly invented the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xpogo Rio
Extreme Pogo is an action sport which involves riding and performing tricks using a pogo stick. The sport draws inspiration from other action sports such as skateboarding, BMX, and parkour. Athletes will have various focuses in tricks or street style bouncing using urban environments as obstacles. Extreme pogo can be seen in athlete exhibition teams, content on sites such as YouTube, and also the annual Pogopalooza: The World Championship of Pogo, which has been held worldwide, although is currently based in Wilkinsburg, Pennsylvania, home of Xpogo, a business which produces the competition and manages many properties in the world of extreme pogo. History Beginnings The beginnings of Extreme Pogo are contested, but it is acknowledged among the pogo community that Dave Armstrong from Provo, Utah, was likely the first individual in the 20th century to make a conscious and consistent effort to execute tricks on a traditional steel spring pogo stick, beginning in 1999. Dave created a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vurtego
] Vurtego Pogo Sticks are a variation of traditional pogo sticks that use air as the spring mechanism for jumping, instead of a traditional metal coil spring. These pogo sticks are designed to achieve extreme heights and allow riders to perform a wide variety of tricks. There are a variety of advantages in using an air-powered pogo stick, ranging from adjustable spring tensions to overall weight to power ratio. The air spring within a Vurtego pogo stick allows riders to pump the pogo stick up to their preferred air pressure in order to jump. The more air pressure that is pumped into the pogo stick, the stiffer the spring becomes. The same Vurtego pogo stick can be used by a 75 lb kid or a 300 lb fully grown adult, simply by adjusting the air pressure. Due to the air spring that is used in the Vurtego's pogo sticks, there is no maximum weight limit. An air spring has advantages over other forms of pogo stick propulsion. An air spring weighs just about nothing compared t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
