Roundnet
Roundnet (also known as Spikeball) is a ball game created in 1989 by Jeff Knurek, inspired primarily by concepts from volleyball. The game is played between two teams, usually with two players each. Players initially line up around a small trampoline-like net at the start of a point and starts with a serve from one team to another. Teams alternate hitting the ball back to the net. Roundnet experienced a revival in 2008 when Spikeball Inc. began manufacturing and promoting its roundnet equipment, with "spikeball" becoming a common name for the game. Basics Roundnet features elements from sports such as volleyball and four square. The game is played between two teams. Two people per team for 2v2 games, or teams have 3 people for 3v3 games. For 2v2 games, players are positioned at 4 points around the net, with partners located at neighboring positions. For 3v3 games, players are positioned at 6 points around the net, with members from each team alternating positions so that each ...

Spikeball (company)
Spikeball Inc. is an American sports equipment company that chiefly produces equipment for the game of roundnet. The company is the largest provider of roundnet equipment and sponsors tournaments in several countries including Belgium, Canada, Colombia, and the United States. The company was founded in 2007 by Chris Ruder and is based in Chicago, Illinois — with employees all over the country. Spikeball Roundnet Association tournaments began airing on ESPN2 in May 2018. History The company was incorporated in 2007 and in 2008 began selling equipment for roundnet, a net sport that had been invented in the 1980s by Jeff Knurek, an American toymaker who did not patent it. Roundnet, as the game is now known, is played with a small trampoline-like net placed on the ground between two teams with two players each who bounce a ball back and forth on the net, in a gameplay that has been compared to volleyball. Ruder had purchased a set when it was originally marketed, briefl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossnet
Crossnet (also known as CROSSNET) is an American sports equipment company that produces a four-way volleyball game of the same name. Crossnet is a combination of volleyball and four square, in a competitive game. History In 2017, the game was devised in the farm town of Woodstock, Connecticut by brothers Chris and Greg Meade and their childhood friend Mike Delpapa, with inspiration from KanJam and four square. Chris said in interview that, to some degree, the motivation he and his brother had to create the company came from the experience of losing their father in 2012. In 2014, Chris graduated from Quinnipiac University with a film degree, and Delpapa graduated from Northeastern University with an engineering degree. In 2012, Greg enrolled at Eastern Connecticut State University with a marketing degree before dropping out in order to pursue entrepreneurial ventures. At the time the idea was conceived in May 2017, Chris was working at the Uber HQ as an Account Executive helping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Square
Four square (also called handball, champ, four squares or box ball) is a global sport played on a square court divided by two perpendicular lines into four identical boxes creating four squares labelled 1–4 or A–D. Four square is a popular game at elementary schools with little required equipment, almost no setup, and short rounds of play that can be ended at any time. The game also has a large following for adults in many communities. History Four square dates to at least the 1950s. A game called four square is mentioned in newspapers in the northeastern United States at least as far back as the 1950s, but the rules are not explained. A 1953 teacher's manual describes four square with the same rules used today. However, it is possible this game could have evolved from " Jeu de paume", a game popular in France as early as the twelfth century. Rules One player occupies each of the 4 squares at a time; the other players wait in line. The player in square 4 serves the ball i ...

Net And Wall Games
Net and wall games are court games where either a net separates the opponents or a wall serves to reflect the ball to the opponent. The object of these games is to hit or throw the ball or bird over the net or against the wall back to the opponent. Play typically begins with one side ''serving'' the ball/bird by initially tossing or releasing it and then hitting/throwing it over the net or to the wall. This then starts a ''rally'', in which the sides alternate hitting/throwing the ball/bird. Players then score points whenever the opponent fails to return the ball/bird back. The criteria on what is considered a valid return varies between each sport (such as the number of times the ball may be touched or bounced on a player's side before it must go back). Sports like Real tennis, Padel and Wallyball use both net and walls. Some sports like Four square, Ballon au poing, Tamburello and Roundnet has the same logic of wall games using the floor or trampoline in the rebounding funct ...

Serve (volleyball)
Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since Tokyo 1964. Beach volleyball was introduced to the program at the Atlanta 1996 Summer Olympics. The adapted version of volleyball at the Summer Paralympic Games is sitting volleyball. Basic play The complete set of rules is extensive, but play essentially proceeds as follows: a player on one of the teams begins a 'rally' by serving the ball (tossing or releasing it and then hitting it with a hand or arm), from behind the back boundary line of the court, over the net, and into the receiving team's court. The receiving team must not let the ball be grounded within their court. The team may touch the ball up to three times to return the ball to the other side of the court, but individual players may not touch the b ...

Generic Trademark
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, because of its popularity or significance, has become the generic term for, or synonymous with, a general class of products or services, usually against the intentions of the trademark's owner. A trademark is prone to genericization, or "genericide", when a brand name acquires substantial market dominance or mind share, becoming so widely used for similar products or services that it is no longer associated with the trademark owner, e.g., linoleum, bubble wrap, thermos, and aspirin. A trademark thus popularized is at risk of being challenged or revoked, unless the trademark owner works sufficiently to correct and prevent such broad use. Trademark owners can inadvertently contribute to genericization by failing to provide an alternative generic name for their product or service or using the trademark in similar fashion to generic terms. In one example, the Oti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trampoline
A trampoline is a device consisting of a piece of taut, strong fabric stretched between a steel frame often using many coiled spring (device), springs. People bounce on trampolines for recreational and competitive purposes. The fabric that users bounce on (commonly known as the "bounce mat" or "trampoline bed") is not elastic itself; the elasticity is provided by the springs that connect it to the frame, which store potential energy. History Early trampoline-like devices A game similar to trampolining was developed by the Inuit, who would toss blanket dancers into the air on a walrus skin one at a time (see Nalukataq) during a spring celebration of whale harvest. There is also some evidence of people in Europe having been tossed into the air by a number of people holding a blanket. Mak in the Wakefield Mystery Play ''The Second Shepherds' Play'', and Sancho Panza in ''Don Quixote'', are both subjected to blanketing – however, these are clearly non-voluntary, non-recrea ...

Bouncing Ball
The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high school or undergraduate level physics courses. However, the exact modelling of the behaviour is complex and of interest in sports engineering. The motion of a ball is generally described by projectile motion (which can be affected by gravity, drag, the Magnus effect, and buoyancy), while its impact is usually characterized through the coefficient of restitution (which can be affected by the nature of the ball, the nature of the impacting surface, the impact velocity, rotation, and local conditions such as temperature and pressure). To ensure fair play, many sports governing bodies set limits on the bounciness of their ball and forbid tampering with the ball's aerodynamic properties. The bounciness of balls h ...
