Description
Ring beregnet til bruk i sportsutstyr. Ring intended for use in sports equipment.
Foreliggende oppfinnelse vedrører en ring beregnet til The present invention relates to a ring intended for
å holde en snor til hvilken det er festet en ball , hvilken ring er beregnet til å gli på et sportsapparat som omfatter en vertikal stang med et skrueformet legeme ved sin øvre ende i likhet med en skruefjær hvorpå nevnte ring er beregnet å gli. Ballen som er festet til snoren er beregnet til å bli slått frem og tilbake ved hjelp av en racket, balltre eller lignende, hvorved ringen på det skrueformede legeme kan bringes til å bevege seg oppover eller nedover på skruelegemet avhengig av hvorvidt ballen blir slått slik at den svinger i eller mot urviser-ens retning. Det er åpenlyst at ringen blir utsatt for vesentlig frik- to hold a cord to which is attached a ball, which ring is intended to slide on a sports apparatus comprising a vertical bar with a helical body at its upper end similar to a coil spring on which said ring is intended to slide. The ball attached to the string is intended to be hit back and forth by means of a racket, bat or the like, whereby the ring on the screw-shaped body can be caused to move up or down on the screw body depending on whether the ball is being hit so that it swings in or counter-clockwise direction. It is obvious that the ring is subjected to substantial free-
sjonsslitasje samt også blir utsatt for diametrale, påkjenninger. Slag-kraften bør ideelt være tangensial til svingesirkelen for ballen og en-hver kraft som ikke blir tilført i en slik retning vil bevirke et sjokk i ringen. -I noen tilfeller kan sjokket resultere i en plutselig stopp av ballens bevegelse. i sion wear as well as being exposed to diametrical stresses. The impact force should ideally be tangential to the swing circle of the ball and any force not applied in such a direction will cause a shock in the ring. -In some cases, the shock may result in a sudden stop of the ball's movement. in
Det er tidligere erkjent at det må fjorefinnes en viss elastisitet i forbindelsen mellom sportsapparatets' stang og selve ballen for å dempe de eventuelt oppstående sjokk og det er i denne forbindelse * vært prøvet med fjærende skruefjærer på toppen av stangen samt med en viss elastisitet i linen. Disse løsninger har ikke vist seg helt vellykkede idet ballen har fått en tendens til å forandre retning og derved skyte "uberegnelig" tilbake slik! at spillerne van-skelig kan beregne hvilken retning ballen vil bevege seg. It has previously been recognized that there must be a certain elasticity in the connection between the sports equipment's rod and the ball itself in order to dampen any shocks that may arise, and in this connection * has been tested with springy coil springs on top of the rod as well as with a certain elasticity in the line . These solutions have not proven to be entirely successful as the ball has had a tendency to change direction and thereby shoot "unpredictably" back like this! that the players can hardly calculate which direction the ball will move.
Det er således et formål ved den foreliggende oppfinnelse å nedsette eller eliminere de ovennevnte ulemper! og dette er oppnådd ved at ringen fremstilles av et materiale med fjærbnde egenskaper og gjøres fjærende, deformerbar hovedsakelig i diametrale retninger, dvs. at den ved påkjenning deformeres fra sin ringform til en oval form, ved at ringen-.gis et hovedsakelig eliptisk tverrsniitt med elipsens minste akse radiell i ringen. It is thus an aim of the present invention to reduce or eliminate the above-mentioned disadvantages! and this is achieved by making the ring from a material with spring-like properties and making it springy, deformable mainly in diametrical directions, i.e. that it is deformed from its ring shape to an oval shape when stressed, by giving the ring a mainly elliptical cross-section with minor axis of the ellipse radial in the ring.
Ringen kan utføres av et hensiktsmessig syntetisk plast-materiale som f.eks. nylon eller lignende eller av! metall. The ring can be made of a suitable synthetic plastic material such as e.g. nylon or similar or off! metal.
De karakteristiske trekk ved ringen yil fremgå av det etterfølgende krav samt at ringen ifølge oppfinnelsen vil bli beskrevet i det følgende med henvisning til tegningen hvor The characteristic features of the ring will be apparent from the subsequent claim and that the ring according to the invention will be described in the following with reference to the drawing where
fig.l viser en ideell type sportsutstyr ved hvilket ringen ifølge oppfinnelsen er hensiktsmessig i bruk, og fig.l shows an ideal type of sports equipment in which the ring according to the invention is suitable for use, and
fig.2 er et perspektivriss av en halv ring for tydelig fig.2 is a perspective view of a half ring for clarity
å vise ringlegemets tverrsnitt. to show the annulus cross-section.
Fig.l viser sportsutstyret omfattende en stang 10 med Fig.l shows the sports equipment comprising a pole 10 with
i in
et skruelegeme anordnet ved stangens topp. En ringj 14 er glidbart anordnet på skruelegemet og bærer en snor 16 til hvis annen ende.det er festet en ball 18. a screw body arranged at the top of the rod. A ring 14 is slidably arranged on the screw body and carries a string 16 to the other end of which a ball 18 is attached.
Ringen 14 er fremstilt av nylon, e-ller lignende plastma-teriale og '~ar et hovedsakelig eliptisk: tverrsnitt: som vist i fig. 2 idet elipsens minste akse løper radielt i ringen'. Det oppnås herved som tidligere angitt en god-fjæring i ringen i dennes diametrale retninger hvorved det videre oppnås en god sjokkdempning under spillets gang ..lik at de før nevnt ulemper ved at ballen plutselig iopper i sin bevegelse eller fortsetter i uberegnelige retninger, unngås. The ring 14 is made of nylon or similar plastic material and has a mainly elliptical cross-section as shown in fig. 2 as the minor axis of the ellipse runs radially in the ring'. This achieves, as previously stated, a good suspension in the ring in its diametrical directions, whereby a good shock absorption during the course of the game is also achieved, such that the previously mentioned disadvantages of the ball suddenly jumping in its movement or continuing in unpredictable directions are avoided.
