Abstract

A device for automatic changing of a racket's centre of mass is changing the racket's centre of mass in a simple way by means of a spring (1) and a weight (2) on which the centrifugal force is acting. The spring (1) and the weight (2) are interconnected within the device for automatic changing of racket's centre of mass and are mounted within the racket's neck. In the case of non-acting of the centrifugal force or under insufficient amount of the latter, the racket's centre of mass remains closer to the racket's middle and enables easier manipulation of the racket. When a certain centrifugal force is exceeded, the weight (2) approaches the racket's head and thus shifts the racket's centre of mass and contributes to a greater hitting force of the racket.

Description

NAPRAVA ZA AVTOMATSKO SPREMINJANJE TEŽIŠČA LOPARJAAUTOMATIC CHANGE WEIGHT CHANGE DEVICE

Predmet izuma je naprava za avtomatsko spreminjanje težišča lopaija oz. bolj natančno naprava, ki ob prisotnosti centrifugalne sile avtomatsko spremeni težišče lopaija. Uporabna je predvsem za badmintonski lopar in za ostale športe z žogo in loparjem.The subject of the invention is a device for automatically changing the center of gravity of a lopai. more specifically, a device that automatically changes the center of gravity of the blade in the presence of centrifugal force. It is especially useful for badminton racket and other sports with ball and racket.

Tehnični problem, ki ga rešuje: Lopaiji, ki nudijo večjo okretnost in natančnost imajo težišče loparja bližje držalu lopaija. Loparji z večjo močjo pri udarca imajo težišče lopaija bližje glavi lopaija. Serijsko izdelani lopaiji imajo torej težišče ali bližje držalu lopaija ali bližje glavi loparja. Igralec mora izbrati eno od možnosti. Izum združi obe možnosti v istem lopaiju.A technical problem that solves it: Thieves that offer greater agility and precision have the center of gravity of the racket closer to the racket holder. Higher-power lobsters have the center of gravity of the loboi closer to the loboi's head. Serially manufactured blades therefore have a center of gravity or closer to the blades holder or closer to the blades head. The player must choose one of the options. The invention combines the two options in the same lobo.

Že znane rešitve so:Known solutions are:

1. US patent No.: 6,623383 B3 in US patent No.:4,325549, kjer se težišče lopaija ne povrne avtomatsko v prvotno lego in tako uporabniku (igralcu) ne omogoča intenzivne uporabe (dinamika igranja).1. U.S. Patent No. 6,623383 B3 and U.S. Patent No.:4,325549, wherein the focal point of the blade is not automatically restored to its original position and thus does not allow the user (the player) to use intensively (game dynamics).

2. US patent No.: 6,575,854 BI in US patent No.: 5,779,571, kije praktično neizvedljiv, ker dodaja več konstrukcijskih elementov, ki povečujejo težo lopaija in kjer utežni elementi potujejo po ohišju glave lopaija - po krivi poti, kar povečuje pokvarljivost elementov (zatikanje).2. US Patent No .: 6,575,854 BI and US Patent No .: 5,779,571, which is practically impracticable because it adds more construction elements that increase the weight of the blade and where the weight elements travel on the blade head housing - down the wrong path, increasing the perishability of the elements ( pinching).

-2Napravo za avtomatsko spreminjanje težišča loparja sestavljata vzmet (1) in utež (2). Lopar sestavljajo glava lopaija in vrat loparja z držalom. Napravo za avtomatsko spreminjanje težišča lopaija je vgrajena v vrat lopaija.-2The device for automatically changing the center of gravity of the racket consists of a spring (1) and a weight (2). The bowler consists of the head of the lobster and the neck of the racket with the holder. A device for automatically changing the center of gravity of the blade is built into the neck of the blade.

Izum naprave za spreminjanje težišča lopaija je v konstrukciji in poziciji v lopaiju, kar ga razlikuje od do zdaj znanih podobnih patentov.The invention of the device for changing the center of gravity of the lopai is in the construction and position in the lobai, which distinguishes it from similar patents known so far.

Konstrukcija naprave po izumu: Utež (2) in vzmet (1) sta spojeni. Pozicija vzmeti (1) je bližje glavi lopaija, utež (2) je bližje držalu lopaija. Utež (2) je vodena z obliko vratu lopaija.Construction of the device according to the invention: Weight (2) and spring (1) are connected. The position of the spring (1) is closer to the blade head, the weight (2) is closer to the blade holder. The weight (2) is guided by the shape of the neck of the hatch.

DELOVANJE: Ob nedelovanju centrifugalne sile ali ob nezadostni količini le te, ostaja težišče lopaija bližje sredini lopaija in omogoča lažjo manipulacijo z loparjem. Ob prekoračitvi določene centrifugalne sile se utež (2) približa glavi lopaija in tako premakne težišče lopaija bližje glavi lopaija in pripomore k večji udarni sili lopaija.OPERATION: With the centrifugal force not working or with insufficient amount of force, the center of the lopai remains closer to the center of the lopai and enables easier manipulation of the lobster. When a certain centrifugal force is exceeded, the weight (2) approaches the loboi head, thus moving the focal point of the loboi closer to the loboi head and contributes to the greater impact force of the lopai.

Prednosti pred ostalimi rešitvami:Advantages over other solutions:

- Vzmet j e tlačnega tipa.- Pressure type spring.

2- Utež potuje premo po ravni podlagi2- The weight travels straight on a level surface

3- Sprememba težišča je v optimalnem območju.3- The change of center of gravity is in the optimal range.

4- Ena utež.4- One weight.

5- Izbira materiala za utež, ki je iz volframa ali zlata.5- Choosing a weight material that is tungsten or gold.
