Abstract

The arrangement comprises a first inner, elongated element (2) such as a bar, surrounded by a second element (1) and third element (3) adjacent to the second element. All three elements are movable w.r.t. one another in the free arrangement setting. The first element is sepd. from the second and third elements by a gap. The arrangement also has a cap is inserted radially into a peripheral cavity (7) on the inside of the second element. The surface dimensions of the cap is less than those of the cavity. The gap (D1) between the cap and the inside of the second element cavity region is greater than the gap (D2) between the cap and the first element. A fixed track ring (5) and a movable track ring (6) have angled ends locating in the cavity region of the second element. The first element is passed through the gap. A barrier body is provided on the side of the first element adjacent to the third element and facing the second element. A body (9) applies force to the cap during locking together of the three elements so that the cap extends radially into the cavity and urges against the first element and the track rings of the second element to fix the third element against the barrier body.

FIGURBESKRIVNTNG Fig 1 visar en låsanordning som är påmonterad en stång och där låsanordningens rörliga löpring trycker mot en på stången påhängd vikt.FIGURE DESCRIPTION Fig. 1 shows a locking device which is mounted on a rod and where the movable device of the locking device running ring presses against a weight attached to the bar.

BESKRIVNING Av LÅSANORDNINGEN Med hänvisning till Fig l betecknas en låsanordning med siffran 1. Denna utgör samtidigt det yttre av de båda element som skall låsas till det första elementet som utgörs av en cylindrisk stång 2 som i sin tur har ett påmonterat löstagbart element 3, i patentkravet benämnt tredje element.DESCRIPTION OF THE LOCKING DEVICE With reference to Fig. 1, a locking device is denoted by the number 1. This constitutes at the same time the exterior of the two elements to be locked to the first element consisting of one cylindrical rod 2 which in turn has a mounted detachable element 3, in the claim called third element.

Elementet 1 består av en yttre manschett 4 och inuti denna manschett en cylindrisk fast löpring 5 i ena ändan samt en i axiell riktning rörlig löpring 6 i andra ändan. Löpringen 5 är förenad med manschetten 4 genom pressning, limning, svetsning etc. På detta sätt erhålls i elementet 1 ett urtag 7 mellan löpringarna 5 och 6. I urtaget 7 är anordnad en hylsa 8 med tunnare väggtjocklek än löpringama 5 och 6.The element 1 consists of an outer cuff 4 and inside this cuff a cylindrical fixed running ring 5 at one end and a running ring 6 movable in the axial direction at the other end. Running ring 5 is connected to the cuff 4 by pressing, gluing, welding, etc. In this way in the element 1 a recess 7 is obtained between the running rings 5 and 6. In the recess 7 a sleeve 8 with a thinner wall thickness than the running rings 5 and 6.

Hylsans 8 innerdiameter är lika stor som eller något större än löpringamas 5 och 6 innerdiameter, medan hylsans 8 ytterdiameter är något mindre än yttermanschettens 4 innerdiameter i läget för uttaget 7. När hylsan 8 är koaxiell med anordningen l bildas sålunda en spalt mellan hylsan 8 och yttermanschetten 4. Denna spalt som utgör hylsans 8 spel i urtaget har betecknats Dl. I yttermanschetten 4 är gängat ett hål van' det sitter en skruv 9, med vars hjälp hylsan 8 kan forskjutas i radiell riktning i urtaget 7.The inner diameter of the sleeve 8 is equal to or slightly larger than the running rings 5 and 6 inner diameter, while the outer diameter of the sleeve 8 is slightly smaller than that of the outer sleeve 4 inner diameter in the position of the socket 7. When the sleeve 8 is coaxial with the device 1 is formed thus a gap between the sleeve 8 and the outer sleeve 4. This gap which constitutes the sleeve 8 games in the recess have been designated Dl. A hole is threaded in the outer cuff 4, there is one screw 9, by means of which the sleeve 8 can be displaced in the radial direction in the recess 7.

Genom det andra och tredje elementet 1 respektive 3 sträcker sig det forsta elementet, dvs stången 2, som på den sida om det tredje elementet som är vänd från det andra elementet 1 uppvisar ett anhåll 10, som enligt utföringsformen består av en ﬂäns. Stången 2 kan löpa i anordningen 1 med ett visst spel i frigångsläget. Spelet mellan stången 2 och låshylsan 8 har betecknats D2. Läsning mellan element l och element 2 erhålls om D1 > D2. Genom att dra åt skruven 9 pressas låshylsan 8 mot stången 2 tills dess stången på motsatt sida stöter emot löpringarna 5 och 6, under förutsättning att Dl > D2. Enligt uppﬁnningen har under tiden som hylsan 8 förskjutits mot stången 2 hylsan 8 också tryckt på det yttre elementets l rörliga löpring 6. Genom kílverkan mellan hylsan 8 och löpringen 6 pressas den senare axiellt mot elementet 3 och fixerar dettai önskat läge mot anhållet 10. 4, .. 513 040 3 Läsning sker sålunda genom fastklämning mellan å ena sidan låshylsan 8 på skruvens 9 sida och å andra sidan de båda löpringama 5 och 6, samt genom den rörliga löpringens 6 förskjutning i förhållande till manschetten 4 och fastklämning av tyngden 3 mot anhållet 10.The first element 1 extends through the second and third elements 1 and 3, respectively. i.e. the rod 2, as on the side of the third element facing away from the second the element 1 has a stop 10, which according to the embodiment consists of an ﬂ end. The bar 2 can run in the device 1 with a certain play in the idle position. The game between the bar 2 and the locking sleeve 8 has been designated D2. Reading between element 1 and element 2 is obtained if D1> D2. By tightening the screw 9, the locking sleeve 8 is pressed against the rod 2 until the rod is on opposite side abuts the running rings 5 and 6, provided that D1> D2. According to During the time that the sleeve 8 has been displaced towards the rod 2, the sleeve 8 has also pressed on the movable running ring 6 of the outer element 1. By the wedge action between the sleeve 8 and the running ring 6 is pressed the latter axially against the element 3 and fixes it in the desired position against it arrested 10. 4, .. 513 040 3 Reading thus takes place by clamping between on the one hand the locking sleeve 8 on the screw 9 side and on the other hand the two running rings 5 and 6, and through the movable running ring 6 displacement relative to the cuff 4 and clamping of the weight 3 against the stop 10.
