Description
Gymnastikkapparat. Gymnastics apparatus.
Der kjennes gymnastikkapparater som tillater utovelse av symmetriske strekk- og trykkrefter. Disse apparater består av to tele-skopiske ror med innvendig kornpres jonsfja:r. Hvert ror avsluttes i sin fri ende av et parti i form av et grep, idet grepene er forbundet med en ikke elastisk kabel i lukket sloyfe med en part på hver side av teleskoprbrene. Dette apparat muliggjor et stort antall symmetrisk rettede bevegelser, men har den mangel at den kraft som kan anvendes er meget begrenset, idet fjæren etter hvert mister sin elastisitet. Glike apparater har videre en begrenset kompresjonsvei, som hurtig blir utilstrekkelig etter hvert som den person som trener, oppnår styrke. Videre omfatter apparatet deler som glir mot hverandre, hvilket i det lange lbp kan innvirke uheldig på funksjoneringen. There are gymnastic devices that allow the practice of symmetrical stretching and pushing forces. These devices consist of two telescopic rudders with internal grain pressure springs. Each rudder is terminated at its free end by a part in the form of a grip, the grips being connected by a non-elastic cable in a closed loop with a part on each side of the telescopic legs. This device enables a large number of symmetrically directed movements, but has the disadvantage that the force that can be used is very limited, as the spring gradually loses its elasticity. Similar devices also have a limited compression path, which quickly becomes insufficient as the person exercising gains strength. Furthermore, the device includes parts that slide against each other, which in the long run can adversely affect the functioning.
Nærværende oppfinnelse tar sikte på et robust gymnastikkapparat med forholdsvis enkel utformning og som videre praktisk talt ikke har noen begrensning m.h.t. de krefter som kan utoves. The present invention aims at a robust gymnastic apparatus with a relatively simple design and which furthermore practically has no limitation with respect to the forces that can be exerted.
Gymnastikkapparatet ifolge oppfinnelsen karakteriseres spesielt ved at det omfatter en solid ramme med flere frie hjbrner eller ben og en i seg selv lukket elastisk kabel som ligger an mot hornene eller ben-endene. The gymnastic apparatus according to the invention is particularly characterized by the fact that it comprises a solid frame with several free legs or legs and an inherently closed elastic cable which rests against the horns or leg ends.
Trekk og fordeler ved oppfinnelsen vil fremgå av nedenstående beskrivelse, som er å betrakte sorn et eksempel, og under henvisning til tegningen hvor: Fig. 1 viser, gymnastikkapparatet ifolge oppfinnelsen sett i plan, og Features and advantages of the invention will be apparent from the following description, which is to be considered as an example, and with reference to the drawing where: Fig. 1 shows the gymnastics apparatus according to the invention seen in plan, and
Fig. 2 viser apparatet sett fra siden.Fig. 2 shows the device seen from the side.
Under henvisning til tegningen omfatter et gymnastikkapparat ifolge oppfinnelsen en solid ramme 1 med fire ben med frie ender 2>3>^ og 5 beliggende i samme plan i de fire hjbrner av et rektangel. I hver ende 2-5 av rammen 1 er det montert en trinse, henholdsvis 6, 7>8 og 9 som er lagret på en aksel tvers på ben-endenes 2-5 plan. Over trinsene 6-9 er lagt en forspent, elastisk kabel 10 som således omfatter fire parter 10a, 10b, 10c og 10d. With reference to the drawing, a gymnastic apparatus according to the invention comprises a solid frame 1 with four legs with free ends 2>3>^ and 5 located in the same plane in the four corners of a rectangle. At each end 2-5 of the frame 1, a pulley is mounted, respectively 6, 7>8 and 9, which is stored on an axle across the plane of the leg ends 2-5. Above the pulleys 6-9 is laid a pre-tensioned, elastic cable 10 which thus comprises four parts 10a, 10b, 10c and 10d.
Rammen 1 utgjores i det viste eksempel av X-formet stopestykke hvis ben la, lb, lc og ld fortrinnsvis er noe buet utover, slik det sees av tegningen. In the example shown, the frame 1 is made of an X-shaped stop piece whose legs la, lb, lc and ld are preferably slightly curved outwards, as can be seen from the drawing.
Det beskrevne gymnastikkapparat er egnet for utovelse av gener-elt symmetriske krefter anvent på de to motsatte parter av kab-i elen 10. P.g.a. sin langstrakte form egner den beskrevne utform-, ning seg.spesielt godt til utovelse av strekkrefter (stilling ,10'a, 10'b) eller trykk (stilling 10"a, 10"b) rettet mot de to The described gymnastic apparatus is suitable for practicing generally symmetrical forces applied to the two opposite parts of the cable 10. P.g.a. due to its elongated shape, the described design is particularly well suited for exerting tensile forces (position 10'a, 10'b) or pressure (position 10"a, 10"b) directed at the two
<korte kabelparter 10a, 10b (i betraktning av de frie avstander mellom grenene (la-lb) og (lc-ld) på armaturen), mens de lange <short cable parts 10a, 10b (taking into account the free distances between the branches (la-lb) and (lc-ld) of the armature), while the long
I IN
kabelparter 10c, 10d er bedre egnet til utovelse av strekk (stilling 10'c, 10'd) og trekk (etter:pilenes f eller f retning). Ved å fastholde den ene, av apparatets ender (2, 3) eller (W, 5) kan man også utove lbfte- eller trykkbevegelser på parten 10b eller 10a. cable parts 10c, 10d are better suited for stretching (position 10'c, 10'd) and pulling (in the direction of the arrows f or f). By holding one of the device's ends (2, 3) or (W, 5), it is also possible to carry out lifting or pressing movements on part 10b or 10a.
Et gymnastikkapparat forarbeidet ifolge oppfinnelsen hadde en lengde på 91 cm og en bredde på 27 cm. Rammen var utfort i stbpt aluminiumslegering, og vekten var 2,2 kg. A gymnastic apparatus prepared according to the invention had a length of 91 cm and a width of 27 cm. The frame was made of stbpt aluminum alloy, and the weight was 2.2 kg.
Den elastiske kabel var av spesielt robust gummi. Kabelens elas-tisitetskoeffisienter ble tilpasset ettersom apparatet var be-regnet på en trenet idrettsmann eller ikke, på en mann, en kvin-ne eller et barn. En kabel for idrettsmenn hadde i brukssonen en forlengelseskoeffisient på ca. 0,5 til 2 % pr. kg strekk. En kabel for en mann i begynnelsen av treningen hadde en forlengelseskoeffisient på ca. 2 til 5 % pr. kg strekk, mens en kabel for kvinner eller barn hadde en forlengelseskoeffisient som kunne overstige 15 % pr. kg strekk. The elastic cable was made of particularly robust rubber. The cable's elasticity coefficients were adjusted according to whether the device was designed for a trained athlete or not, for a man, a woman or a child. A cable for sportsmen had an elongation coefficient of approx. 0.5 to 2% per kg stretch. A cable for a man at the beginning of training had an extension coefficient of approx. 2 to 5% per kg stretch, while a cable for women or children had an elongation coefficient that could exceed 15% per kg stretch.
Den elastiske kabel legges i lukket slbyfe fortrinnsvis med en forspenning på 5 til 15 kg svarende til en forlengelse på ca. 10 til ^-0 %. The elastic cable is laid in closed slbyfe preferably with a pretension of 5 to 15 kg corresponding to an extension of approx. 10 to ^-0%.
Kabelens vekt var 0,5 til 0,7 kg, slik'at apparatets totalvekt var på ca. 2,7 til 2,9 kg. The weight of the cable was 0.5 to 0.7 kg, so that the total weight of the device was approx. 2.7 to 2.9 kg.
Apparatets ovenfor nevnte dimensjoner svarer til det "som passer for en mann av midlere korpulens, men selvsagt kan der utfores modeller med stbrre eller mindre dimensjoner tilpasset de forskjellige menneskelige mål, heri innbefattet mål for barn i forskjellige aldre. The above-mentioned dimensions of the device correspond to what is suitable for a man of medium corpulence, but of course models with larger or smaller dimensions adapted to the different human measurements, including measurements for children of different ages, can be made.
Man har funnet at den rektangulære form har fordeler ved bruk og håndtering, men også kvadratisk utformning kan være brukbar. It has been found that the rectangular shape has advantages in terms of use and handling, but a square design can also be used.
Rammen kan gjbres lettere ved å bruke andre materialer enn met-all, f.eks. visse plastmaterialer eller endog tre. The frame can be made easier by using materials other than metal, e.g. certain plastic materials or even wood.
En forenklet, men vesentlig mindre effektiv utformning, består iA simplified, but significantly less effective design consists of

For eksempel kan den stive ramme oppvise flere hjbrner eller benender anbragt i samme plan eller i forskjellige plan, den stive rammens benender kan anbringes i hjbrnene av hvilken som helst polygon, og selve kab- mning, and also includes other variants. For example, the rigid frame can have several corners or leg ends placed in the same plane or in different planes, the rigid frame's leg ends can be placed in the corners of any polygon, and the cabin itself
