Opfindelsen angår en sikkerheds indretning af den i krav 1' s indledning angivne type.The invention relates to a safety device of the type specified in the preamble of claim 1.
Fra US-patentskrift nr. 4.010.788 kendes en boltforseglingsindretning med en gevindskåren bolt, hvorpå der kan 5 optages en rotationslås.US Patent No. 4,010,788 discloses a bolt sealing device with a threaded bolt on which a rotary lock can be accommodated.
Fra U.S. patentskrift nr. 2.228.738 kendes en sikkerhedsforseglingsindretning til hindring af relativ bevægelse imellem to dele af en ventil. Denne forseglingsindretning omfatter et skaft, som har en skulder ved den ene ende, et hult hoved for skaftet 10 indrettet til optagelse af skulderen, samt midler til at fastgøre hovedet på skaftet omfattende et eftergiveligt element, som befinder sig inden i hovedet, og som er indrettet til at gå i indgreb med den på skaftet tildannede skulder. Forseglings indretningerne har endvidere en destruerbar dækdel, som er således 15 anbragt, at den dækker enden af hovedet og hindrer adgang til det eftergivelige element* Inden i hovedet findes der endvidere midler til at holde dækdelen fast på plads.From the U.S. Patent No. 2,228,738 discloses a safety sealing device for preventing relative movement between two parts of a valve. This sealing device comprises a shaft having a shoulder at one end, a hollow head of the shaft 10 adapted for receiving the shoulder, and means for attaching the head to the shaft comprising a resilient member which is inside the head and which is arranged to engage the shoulder formed on the shaft. The sealing devices further have a destructible cover portion which is arranged so as to cover the end of the head and obstruct access to the resilient member. In addition, within the head there are means for holding the cover portion in place.
Sikkerheds indretningen ifølge opfindelsem er ejendommelig ved, at fjederorganet har en ydre kant med en i hovedsagen skiveformet 20 form, som fastholdes imellem skulderhætten og nippelhætten, samt en centralt placeret.keglestubformet konisk del, hvori der er tildannet spalter til afgrænsning af låsefingrene. Boltdelen kan have forskellige længder og diametre, og låsen kan ikke fjernes fra bolten uden beskadigelse af konstruktionen, således at det 25 vil være klart for en observatør, at der er blevet pillet ved bolten og låsen.The safety device according to the invention is characterized in that the spring means has an outer edge having a generally disc-shaped 20 which is held between the shoulder cap and the nipple cap, and a centrally located cone-shaped conical part in which slots are formed for defining locking fingers. The bolt part may have different lengths and diameters and the lock cannot be removed from the bolt without damage to the structure, so that it will be clear to an observer that the bolt and lock have been peeled.
Andre formål, træk og fordele ved opfindelsen vil fremgå af den efterfølgende beskrivelse af en foretrukken udførelsesform for opfindelsen under henvisning til tegningen, hvor 30 fig. 1 viser et snit, som viser bolten og låsemekanismen i brug, fig. 2 låseindretningen, set fra enden, 2 DK 166463 B1 fig. 3 et partielt snit igennem låseindretningen, fig. 4 et snit efter linien XV-IV i fig. 3, og fig. 5 et tværsnit, som viser en låsefjeder ifølge opfindelsen.Other objects, features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention with reference to the drawing, in which: FIG. 1 is a sectional view showing the bolt and locking mechanism in use; FIG. 2 shows the locking device, seen from the end, 2 FIG. 3 is a partial section through the locking device; FIG. 4 is a sectional view taken along line XV-IV of FIG. 3, and FIG. 5 is a cross-sectional view showing a locking spring according to the invention.
Den i fig. 1 viste boltlås ifølge opfindelsen er forsynet med 5 det generelle henvisningstal 10. Den omfatter en bolt, som har et hoved 13 med en krum overflade og en cylindrisk del 14, og som er forbundet med boltens hovedskaft 15 ved hjælp af en runding 16. En tilspidset del 17 forbinder hoveddelen 15 af skaftet med en smallere del 18, som er forsynet med en rille 19 10 ved hjælp af en tilspidsning af en del af den smallere del 18 frem til en skulder 21. En cylindrisk hoveddel 22 står i forbindelse med skulderen 21 og har en tilspidset ende 23, således som vist.The FIG. 1 the bolt lock according to the invention is provided with 5 the general reference numeral 10. It comprises a bolt having a head 13 having a curved surface and a cylindrical part 14, and which is connected to the bolt head shaft 15 by means of a rounding 16. A tapered portion 17 connects the body portion 15 of the shaft to a narrower portion 18 provided with a groove 19 10 by means of a taper portion of the narrower portion 18 to a shoulder 21. A cylindrical body portion 22 communicates with the shoulder. 21 and has a tapered end 23, as shown.
Låsemekanismen 24 omfatter tre dele bestående af en skulderhætte 15 26, en nippelhætte 27 og et fjederorgan 36. Skulderhætten har en første cylindrisk del 28, som i den låste position passer omkring boltens smallere del 18. Skulderhætten har også en udadragende del 29 og en dækdel 26 og en ydre bueformet del 31, som fastlåser nippelhætten 27 og fjederen 36. Nippelhætten 27 20 har en cylindrisk del 34 og en indadragende del 33, som danner en hætte, der dækker enden 23 af bolten.The locking mechanism 24 comprises three parts consisting of a shoulder cap 15 26, a nipple cap 27 and a spring member 36. The shoulder cap has a first cylindrical portion 28 which fits in the locked position around the narrower portion of the bolt. The shoulder cap also has an outwardly extending portion 29 and a cover portion. 26 and an outer arcuate portion 31 which locks the nipple cap 27 and spring 36. The nipple cap 27 20 has a cylindrical portion 34 and an inwardly extending portion 33 which forms a cap covering the end 23 of the bolt.
Fjederen 36 er fastlåst imellem delene 26 og 27, således som vist i fig. 3. Fjederen 36 har en skiveformet del 38, som er tildannet med en ydre kant 37, samt en i hovedsagen keglestubformet konisk 25 del, som er opdelt ved hjælp af spalter 51, 52, 53, 54, 55 og 56, således at der dannes indadragende fingre 39 ved 44, således som vist i fig. 4. Enderne 50 af fingrene 39 ved 44 er i indgreb med boltdelens 22 skuldre 21, når bolten er indsat i låsemekanismen 24.The spring 36 is locked between the parts 26 and 27, as shown in FIG. 3. The spring 36 has a disc-shaped portion 38 formed with an outer edge 37, and a generally cone-shaped tapered portion 25, which is divided by slots 51, 52, 53, 54, 55 and 56 so that inwardly projecting fingers 39 are formed at 44, as shown in FIG. 4. The ends 50 of the fingers 39 at 44 engage the shoulders 21 of the bolt member 22 when the bolt is inserted into the locking mechanism 24.
30 Ved brug indsættes bolten 10 igennem et par dele 11 og 12, der er tildannet med en central åbning, hvorigennem boltens hoved-In use, the bolt 10 is inserted through a pair of portions 11 and 12 formed with a central opening through which the bolt head
