KOMPASSICOMPASS

Keksintö kohdistuu magneettikompassiin, jossa on runkoon sijoitettu kompassirasia ja siihen laakeroitu kompassiruusu.The invention relates to a magnetic compass having a compass box placed in a body and a compass rose mounted thereon.

5 Rungossa on tähtäysmerkit kompassin suuntaamiseksi ja rasiassa lukemamerkki suunnan lukemiseksi kompassiruusun asteikolta .5 The body has sights to orient the compass and the box has a reading mark to read the direction from the compass rose scale.

Tunnetaan kompasseja, joissa on lasikannella kiinteästi suljettu metallista valmistettu nesteellä täytetty kompassi-10 rasia. Rasiassa on kimmoisa pohja, johon on kiinnitetty pystysuora kannatinkärki. Sen varaan on laakeroitu asteikolla varustettu kompassiruusu. Rasiassa on kompassiruusun vastakkaisilla puolilla tähtäysviivat. Takatähtäysviivaan liittyy lisäksi lukemaviiva, jonka kohdalta suunta luetaan kompassi-15 ruusun asteikolta. Eräänä epäkohtana kuvatunlaisessa kompassissa on se, että tähtäysviivoja, lukemaviivaa ja kompassi-ruusun kannatinkärkeä ei voida säätää täsmällisesti samaan tasoon.Compasses are known in which a liquid-filled compass-10 box made of metal is permanently closed by a glass lid. The box has a resilient base to which a vertical support tip is attached. A compass rose with a scale is mounted on it. The box has sights on opposite sides of the compass rose. The rear line of sight is further associated with a reading line at which the direction is read from the compass-15 rose scale. One drawback of a compass of the type described is that the aiming lines, the reading line and the support tip of the compass rose cannot be adjusted exactly to the same level.

Nyt on keksitty patenttivaatimuksen 1 mukainen kompassi, 20 jossa edellä mainittu epäkohta on ratkaistu. Keksinnön eräitä edullisia suoritusmuotoja on esitetty epäitsenäisissä : vaatimuksissa.A compass according to claim 1 has now been invented, in which the above-mentioned drawback has been solved. Some preferred embodiments of the invention are set out in the dependent claims.

Kuvio 1 esittää poikkileikkausta eräästä keksinnön mukai-: sesta kompassista.Figure 1 shows a cross-section of a compass according to the invention.

25 Kuvion 1 mukaisen kompassin pääosat ovat kompassirasia 1, runkokappale 2, pohjakappale 3 ja asennusrengas 4.The main parts of the compass according to Figure 1 are a compass box 1, a body 2, a base 3 and a mounting ring 4.

Kompassirasiassa on antimagneettisesta metallista, kuten messingistä valmistettu sylinterimäinen runko 5. Se on ala-päästä suljettu kalvomaisesta antimagneettisesta metallima-30 teriaalista valmistetulla pyöreällä pohjalevyllä 6, joka on juotettu runkoon 5. Pohjalevyssä 6 on rengasmaisia poimuja 7 pohjalevyn kimmoisuuden lisäämiseksi.The compass box has a cylindrical body 5 made of antimagnetic metal, such as brass. It is closed at the lower end by a round base plate 6 made of a film-like antimagnetic metal material 30 soldered to the body 5. The base plate 6 has annular corrugations 7

Pohjalevyn 6 yläpuolelle välin päähän siitä on rungossa 5 olevan ulokkeen 8 varaan asetettu metallinen tukilevy 9, 35 jonka keskelle on kiinnitetty kompassiruusun 10 kannatinkär-ki 11. Tukilevyn 9 päälle on liimaamalla kiinnitetty kuppimainen, valkoinen taustalevy 12, joka toimii optisen kont-- rastin aikaansaamiseksi ja kannattaa siihen asennettua luke- 2 84756 maviivaa ja valaisinta. Taustalevy 12 on valmistettu parhaiten sopivasta muovista. Taus ta levyssä 12 on keskellä aukko 13 ja tukilevyssä 9 vastaavalla kohdalla reikiä 14.Above the base plate 6, at a distance therefrom, a metal support plate 9, 35 is placed on the protrusion 8 in the body 5, in the middle of which a support tip 11 of the compass rose 10 is attached. A cup-shaped white back plate 12 is glued to the support plate 9 to provide optical contrast. and supports the reading 84486 line and luminaire mounted thereon. The backing plate 12 is made of the most suitable plastic. The back plate 12 has an opening 13 in the middle and holes 14 at the corresponding point in the support plate 9.

Rungon 5 yläreunassa on O-rengastiiviste 15 ja sen päällä 5 lasilevy 16. Lasilevy 16 on painettu päältäpäin vasten tii-vistysrengasta 15 metallisen kierrerenkaan 17 avulla, joka kiinnittyy runkoon 5 kierteityksen avulla.At the upper edge of the body 5 there is an O-ring seal 15 and on it 5 a glass plate 16. The glass plate 16 is pressed against the sealing ring 15 from above by means of a metal threaded ring 17 which is fixed to the body 5 by means of a thread.

Rungossa 5 on ruuvin 18 avulla tiiviisti suljettava nesteen täyttöaukko 19. Taustalevyssä 12 on vastaavalla kohdal-10 la aukko 20.The body 5 has a liquid filling opening 19 which can be tightly closed by means of a screw 18. The back plate 12 has an opening 20 at a corresponding point-10a.

Pohjalevyn kimmoisan rakenteen ansiosta lämpötilan muutosten aiheuttamat rasian sisältämän nesteen tilavuuden muutokset saadaan kompensoiduksi.Thanks to the resilient structure of the base plate, the changes in the volume of the liquid contained in the box caused by temperature changes can be compensated.

Kierrerenkaan 17 ulkokehässä on rengasmainen uloke 21, 15 jonka yläpinta on alaspäin viisto ja alapinta vaakasuora.The outer circumference of the helical ring 17 has an annular projection 21, 15 whose upper surface is inclined downwards and the lower surface is horizontal.

Kierrerenkaan 16 päälle on tiiviisti asetettu muovinen tar-tuntarengas 22, jonka sisäkehässä on ulokerengasta 21 vastaavalla kohdalla rengasmainen ura 23. Tartuntarengas 22 on joustava siten, että se voidaan helposti painaa paikalleen. 20 Ulokerenkaan 21 ja rengasuran 23 muotoilun avulla on tartuntaankaan irtoamista vaikeutettu. Kierrerenkaan 17 ulkokehällä on lisäksi aksiaalisia uria ja tartuntarenkaassa 22 niitä vastaavia haittoja 31, joiden avulla tartuntarenkaan kiertyminen kierrerenkaan suhteen on estetty.A plastic gripping ring 22 is tightly placed on the threaded ring 16, the inner circumference of which has an annular groove 23 at a point corresponding to the cantilever ring 21. The gripping ring 22 is flexible so that it can be easily pressed into place. The design of the outer ring 21 and the annular groove 23 makes it difficult to detach the grip. The outer circumference of the threaded ring 17 further has axial grooves and the gripping ring 22 has corresponding disadvantages 31, by means of which the rotation of the gripping ring with respect to the threaded ring is prevented.

25 Taustalevyyn 12 on kompassiruusun 10 korkeudelle muodos tettu lukemaviiva 24. Kompassiruusun 10 reuna on läpinäkyvä ja sille muodostettua asteikkoa ja lukemaviivaa 24 valaistaan valonlähteenä toimivan beetasäteilijän 25 avulla.A reading line 24 is formed on the back plate 12 at the height of the compass rose 10. The edge of the compass rose 10 is transparent and the scale and reading line 24 formed thereon are illuminated by a beta emitter 25 acting as a light source.

Kompassin runkokappale on alapäästä suljettu pohjalla, 30 jossa on kompassirasian kimmoisaan pohjalevyyn 6 vastaava jousielin 26.The body of the compass is closed at the lower end by a base 30 with a spring member 26 corresponding to the resilient base plate 6 of the compass box.

Kompassin runkokappaleen yläpäässä kompassirasiaa pitää pystysuunnassa paikallaan muovinen asennusrengas 27, joka on kiinnitetty runkokappaleeseen ruuveilla. Asennustenkaan 27 35 sisähalkaisija kompassirasian kohdalla on hieman suurempi kuin kompassirasian ulkohalkaisija. Kompassirasia säädetään asennusrenkaaseen 27 rungon läpi kolmen, renkaan kehälle 120 asteen välein sijoitetun ruuvin 28 avulla, ja säädön jälkeen 3 84756 asennusrengas lukitaan sopivalla liimalla tartuntarenkaa-seen. Näin rasia voidaan kompassia suunnattaessa keskeistää tarkalleen siten, että rungossa akselin vastakkaisilla puolilla olevat tähystysviivat (ei merkitty kuvioon), kompassi-5 ruusun kannatinkärki 11 ja lukemaviiva 24 ovat tarkalleen samassa pystysuorassa tasossa. Ruuvit 28 on sijoitettu renkaan 21 ja uran 23 kohdalle niiden paikallaan pysymisen edelleen varmistamiseksi.At the upper end of the compass body, the compass box is held vertically in place by a plastic mounting ring 27 fixed to the body by screws. The inner diameter of the installations 27 35 at the compass box is also slightly larger than the outer diameter of the compass box. The compass box is adjusted to the mounting ring 27 through the body by means of three screws 28 placed on the circumference of the ring at 120 degree intervals, and after the adjustment 3 84756 the mounting ring is locked to the grip ring with a suitable adhesive. In this way, when the compass is oriented, the box can be centered exactly so that the sight lines (not shown in the figure), the compass-5 rose support tip 11 and the reading line 24 in the body are in exactly the same vertical plane. The screws 28 are positioned at the ring 21 and the groove 23 to further ensure their retention.

Etutähystysviiva on muodostettu runkokappaleen kääntyvään 10 kanteen. Takatähystysviivana taas toimii runkokappaleessa vastakkaisella puolella olevassa prismalaitteessa 32 oleva hahlo. Prismalaitteen 32 avulla voidaan samanaikaisesti seurata lukemaviivaa 24 ja kompassiruusun asteikkoa sekä etu-tähtäysviivaa hahlon läpi. Näin saadaan tähdätyn kohteen 15 suunta tarkasti määritetyksi.A front view line is formed on the pivotable cover 10 of the body. The back view line, on the other hand, is the slot in the prism device 32 on the opposite side of the body. By means of the prism device 32, the reading line 24 and the scale of the compass rose as well as the front aiming line through the slot can be monitored simultaneously. In this way, the direction of the target 15 is precisely determined.

Lukitusrenkaassa 27 on aksiaalisia reikiä ja tartuntaankaan 22 yläpinnan sisäreunassa pieni rengasmainen kolo 29. Reikien kautta voidaan lukitusrenkaan 27 ja tartuntarenkaan 22 väliin tiputtaa esim. sopivaa liuotinta renkaiden liimaa-20 miseksi yhteen. Koloa 29 pitkin liuotin leviää tasaisesti koko kehän ympäri.The locking ring 27 has axial holes and a small annular hole 29 in the inner edge of the upper surface of the gripping ring 22. Through the holes a suitable solvent can be dropped, for example, between the locking ring 27 and the gripping ring 22 to glue the rings together. Along the cavity 29, the solvent spreads evenly around the entire circumference.

Asennusrenkaan 27 reunassa on metallinen vahvikereuna 30.The edge of the mounting ring 27 has a metal reinforcing edge 30.

Kompassin rakenne on valmistusteknillisesti varsin yksinkertainen. Lisäetuna on vielä se, että kompassin osat, myös 25 rasian sisällä olevat, ovat helposti vaihdettavissa. Erityinen etu on se, että radioaktiivinen säteilijä on helposti vaihdettavissa.The construction of the compass is quite simple in terms of manufacturing technology. An additional advantage is that the parts of the compass, including those inside the box, are easily replaceable. A particular advantage is that the radioactive radiator is easily replaceable.
