Description
Tennstifttenner for sprengladninger av enhver art. Spark plug igniter for explosive charges of any kind.
Oppfinnelsen vedrører en tennstifttenner for sprengladninger av enhver art, som er anvendelig både som trekktenner og som trykktenner. The invention relates to a fuse igniter for explosive charges of any kind, which is applicable both as a pull igniter and as a pressure igniter.
Kjente utførelsesformer for slike tennere er imidlertid meget kompliserte og derfor dyre. Foruten bl. a. et hus som opp-tar samtlige deler av tenneren med tennhette og en fjærbelastet tennstift, har disse tennere f. eks. et ved hjelp av en kulesper-ring låsbart med tennstiften samvirkende føringsstykke, som er lagret aksialt"'forskyvbart i huset, samt en likeledes aksialt forskyvbart lagret fjærbelastet pedal. However, known embodiments of such igniters are very complicated and therefore expensive. Besides e.g. a. a housing that accommodates all parts of the lighter with ignition cap and a spring-loaded ignition pin, these lighters have e.g. a guide piece that can be locked with the spark plug by means of a ball locking ring, which is stored axially displaceably in the housing, as well as a similarly axially displaceable spring-loaded pedal.
Foreliggende oppfinnelse går ut på å The present invention is based on
skaffe en tennstifttenner for sprengladninger av enhver art, som virker både som trekktenner og som trykktenner, og hvis funksjon er sikret uansett værforholdene og grunnforholdene, samtidig som frem-stillingsomkostningene er små og pasning og betjening er enkel og sikker. Mere bestemt vedrører oppfinnelsen en tennstifttenner som reagerer på sideveis trekk og sideveis og/eller aksielt trykk for sprengladninger av enhver art, hvor der i det av obtain a fuse detonator for explosive charges of any kind, which works both as a pull detonator and as a pressure detonator, and whose function is ensured regardless of weather conditions and ground conditions, at the same time that the manufacturing costs are low and fitting and operation is simple and safe. More specifically, the invention relates to a fuse igniter that reacts to lateral pull and lateral and/or axial pressure for explosive charges of any kind, where in the
tennerhuset aksielt utragende tennstiftskaft er anordnet en uttagning som fortrinnsvis i form av en rille strekker seg i det minste delvis rundt tennstiftskaftets omkrets, idet et med sideveis trekk eller trykk henholdsvis med aksielt trykk utløsbart, fjærende sperreelement griper inn i uttagningen, og med det ovennevnte formål for øye består oppfinnelsen hovedsakelig i at sperreelementet består av en lukket tråd-fjærbøyle, som i sin lengderetning har to the igniter housing axially projecting spark plug shaft is provided with a recess which preferably in the form of a groove extends at least partially around the perimeter of the spark plug shaft, a springy locking element that can be released by lateral pull or pressure or by axial pressure engages in the recess, and with the above-mentioned purpose for an eye, the invention mainly consists in the locking element consisting of a closed wire-spring hoop, which in its longitudinal direction has two
midtdeler som griper inn i uttagningen i tennstiftskaftet og til hvilke midtdeler der i lengderetningen på begge sider slutter seg sirkelbuer, hvis radier er større enn den utvendige radius av tennstiftskaftet, idet sirkelbuenes tilslutningssteder til midtdelene i området ved uttagningen i tennstiftskaftet har en avstand som er mindre enn uttagningens diameter, og de i uttagningen ikke inntredende deler av tråden støtter seg på tennerhusets endeflate. central parts that engage in the recess in the lighter shaft and to which central parts are joined in the longitudinal direction on both sides by circular arcs, the radii of which are greater than the outer radius of the lighter shaft, as the connection points of the circular arcs to the central parts in the area of the recess in the lighter shaft have a distance that is smaller than the diameter of the recess, and the parts of the wire that do not enter the recess rest on the end surface of the igniter housing.
Et annet fordelaktig trekk er at trådtykkelsen av den som fjærende sperreelement tjenende trådfjærbøyle er mer enn dobbelt så stor som dybden av uttagningen i tennstiftskaftet. Another advantageous feature is that the wire thickness of the wire spring hoop serving as a springy locking element is more than twice as large as the depth of the recess in the spark plug shaft.
Nok et trekk består i at der som utløs-bart sperreelement for den fjærbelastede tennstift anvendes en radielt fjærende og i forhold til tennerhuset sideveis ved trekk og/eller trykk forskyvbar og låsbar lagret kule, hvis radius er større enn dybden av uttagningen i tennstiftskaftet for opptag-ning av kulen. Another feature consists in the fact that a radially springy and lockable bearing ball is used as a releasable locking element for the spring-loaded igniter, and in relation to the igniter housing, laterally displaceable and lockable in relation to the igniter housing, whose radius is greater than the depth of the recess in the igniter shaft for recording -ning of the bullet.
Et eksempel på oppfinnelsens utfø-relse er beskrevet i det følgende under hen-visning til tegningen. An example of the embodiment of the invention is described in the following with reference to the drawing.

Tenneren består hovedsakelig av tennerhuset 6, som kan være fremstilt av me-tall eller temperaturbestandig kunststoff, tennstiften 1, sikringsstiften 2, tennstiftfjæren 5, den på tennerhuset liggende tet-ningskappe 4, bunnippelen 8, tetningskap-pen 9, tennhetten eller forsinkelseskapselen: 12, riflemutteren 11, ringen 3 samt fjærele-, mentet 10. I det indre hulrom av temaer-; huset sitter der en med tennstiftfjæren spent tennstift, som har et halvsirkelfor-mig spor, i hvilket fjærelementet 10 griper inn, hvilket fjærelement ligger an mot ten-' nerhuset og således holder tennstiften i dennes spente stilling..Sikringsstiften og. riflemutteren griper med sin flate mot fjærelementet 10 og holder således dette i spent stilling, slik at en glidning av f j ær-elementet 10 er utelukket. The igniter mainly consists of the igniter housing 6, which can be made of metal or temperature-resistant plastic, the ignition pin 1, the safety pin 2, the ignition pin spring 5, the sealing cap 4 lying on the igniter housing, the bottom nipple 8, the sealing cap 9, the ignition cap or the delay capsule: 12 , the rifle nut 11, the ring 3 as well as the spring element-, ment 10. In the inner cavity of themes-; the housing holds a spark plug tensioned by the spark plug spring, which has a semicircular groove, in which the spring element 10 engages, which spring element rests against the spark plug housing and thus holds the spark plug in its tensioned position..The safety pin and. the rifle nut grips with its surface against the spring element 10 and thus holds this in a tensioned position, so that a sliding of the spring element 10 is excluded.
Trykkraften av fjærelementet 10 er til-strekkelig til å fastholde tennstiften i spent stilling. På enden av trykkfjæren er der,an - bragt en tetningsskive samt en stålskive som hindrer en beskadigelse av tetnings-skivén og en inntrengning av vann, smuss etc. i tennerhuset. Bunnippelen 8 har en innkrenget tennhette eller en innkrenget tennkapsel med forsenkning, som kommer til utløsning ved hurtig nedadgående be-vegelse av tennstiften. The compressive force of the spring element 10 is sufficient to maintain the ignition pin in the tensioned position. At the end of the pressure spring there is a sealing disc and a steel disc which prevents damage to the sealing disc and the penetration of water, dirt etc. into the igniter housing. The bottom nipple 8 has a recessed ignition cap or a recessed ignition capsule with a recess, which is triggered by rapid downward movement of the ignition pin.
Hvis en spenntråd festes til de sirkel-formige ender av fjærelementet 10, og der på spenntråden utøves et bestemt strekk eller trykk, så blir fjærelementet trukket ut av den spente stilling og glir med den ut-videde åpning langs tennstiften. Tennstiften er da befridd og slår an mot tennhetten. Hvis tenneren ved hjelp av pedalen eller en annen belastning tøelastes på det halvsirkulært avrundede tennstifthode, så svinger denne kraft på tennstifthodet fjærelementet 10 ut på midten. Tennstiften er frigjort og bringer tennhetten til å.tenne. If a tension wire is attached to the circular ends of the spring element 10, and where a specific stretch or pressure is applied to the tension wire, the spring element is pulled out of the tensioned position and slides with the widened opening along the ignition pin. The spark plug is then freed and strikes the spark cap. If the igniter is loaded onto the semicircularly rounded spark plug head by means of the pedal or another load, this force on the spark plug head swings the spring element 10 out in the middle. The spark plug is freed and causes the spark cap to ignite.
Det vesentlige ved oppfinnelsen består spesielt i anbringelsen av fjærelementet på tennstiften og den dermed forbundne fast-holdelse av tennstiften. Av betydning er videre at på grunn av sikringsstiften og den riflede mutter kan fjærelementet i sikret tilstand ikke gli frem og tilbake. The essential aspect of the invention consists in particular in the placement of the spring element on the spark plug and the associated retention of the spark plug. It is also important that due to the securing pin and the knurled nut, the spring element cannot slide back and forth in the secured state.
På grunn av den enkle utførelse skaf-fes en trekk- og trykktenner som funksjo-nerer helt sikkert, er økonomisk i frem-stilling og ligger gunstig an med hensyn til pris og lang lagringsevne og levetid. Due to the simple design, a pull and push igniter is obtained which functions completely reliably, is economical to manufacture and is favorable in terms of price and long storage capacity and service life.
Ved den i fig. 5 viste tennstifttenner er tennstiften 1 for lagring av fjærelementet 10 innsnevret til en diameter som omtrent motsvarer den innvendige vidde av fjærelementet i avlastet tilstand, hvorved bl. a. tennstiftens montasje lettes. Videre er tennerhuset forsynt med en konisk endeside, som ved sikringsskruens 2 montasje hindrer en påsetning av det fortrinsvis med flenser forsynte skruehode på husets 6 •mantel. By the one in fig. 5 shown spark plug teeth, the spark plug 1 for storing the spring element 10 is narrowed to a diameter which roughly corresponds to the internal width of the spring element in the unloaded state, whereby a. the spark plug assembly is made easier. Furthermore, the igniter housing is provided with a conical end side, which, when the safety screw 2 is assembled, prevents the fitting of the screw head, which is preferably provided with flanges, on the casing 6 of the housing.
Dessuten foregår avtetningen av husets 6 hulrom i motsetning til utførelsesfor-rnen i henhold til fig. 1 — 4, med en tet-■ningsring 9 som tett omslutter tennstiften 1 og som ved hjelp av tennstiftfjæren 5 trykkes mot en skulder på huset, idet der mellom den .siste vinding av tennstiftfjæren 5 og tetningsringen 9 er anordnet en formfast skive. Moreover, the sealing of the housing's 6 cavities takes place in contrast to the embodiment according to fig. 1 — 4, with a sealing ring 9 which tightly surrounds the spark plug 1 and which is pressed against a shoulder on the housing by means of the spark plug spring 5, with a dimensionally stable disc arranged between the last turn of the spark plug spring 5 and the sealing ring 9.
