Anordningen er dessuten bestemt å muliggjore en stabil til-slutning mellom pipehodet og pipemunnbittet samt å gi tobakkspipen en fra et estetisk synspunkt tiltalende form. - to reduce the supply of material, whether it concerns briar root or other equivalent material, and partly to eliminate the outflow of oil formed during smoking, as well as partly to facilitate the cleaning of the tobacco pipe. The device is also intended to enable a stable connection between the pipe head and the pipe mouthpiece and to give the tobacco pipe an aesthetically pleasing shape. -

Dette er ifolge oppfinnelsen oppnådd ved å utforme og anordne tobakkspipen som angitt i hovedkravets karak-teristikk. Ytterligere karakteristiske trekk ved anordningen ifolge oppfinnelsen fremgår av underkravene. - According to the invention, this is achieved by designing and arranging the tobacco pipe as stated in the characteristics of the main claim. Further characteristic features of the device according to the invention appear from the subclaims. -

Fig. 3 viser i stcirre måle-stokk et tversnitt gjennom anordningen. Fig. 4 viser i samme måle-stokk et perspektivriss av hylsen med dens styre- og bæreorganer, og fig. 5 viser i lengdesnitt en del av pipemunnbittets rokkanal, ved dets endeparti samt et enderiss i dets tverretning. - Fig, 1 is a perspective view of a pipe in which the device according to the invention is placed. Fig. 2 is a longitudinal section through the pipe with the device. Fig. 3 shows on a larger scale a cross-section through the device. Fig. 4 shows, to the same scale, a perspective view of the sleeve with its control and support members, and Fig. 5 shows in longitudinal section a part of the pipe mouthpiece's rook channel, at its end part, as well as an end view in its transverse direction. -

På tegningsfigurene betegner 1 pipehodet, som er fremstilt av briarrot eller liknende tremateriale. Med 2 betegnes pipemunnbittet, som hensiktsmessig er fremstilt av kunstplast eller annet passende materiale. Pipehodet er på vanlig måte forsynt med et for tobakken bestemt gl ei dek amme r 3 fra hvis bunn utgår en rokkanal 4, som munner ut i en vinkelrett på denne rettet boring 5> hvori er anordnet en fra pipehodet 1 utspringende hylse 6, på hvilken pipemunnbittet 2 er anbringbart. - In the drawings, 1 denotes the pipe head, which is made of briar root or similar wood material. 2 denotes the pipe mouthpiece, which is suitably made of plastic or other suitable material. The pipe head is normally provided with a slide designed for tobacco 3 from the bottom of which a rock channel 4 emanates, which opens into a perpendicular to this directed bore 5> in which is arranged a sleeve 6 projecting from the pipe head 1, on which the pipe mouthpiece 2 can be attached. -

I boringens 5 vegg er uttatt to i dens leng-deretning gående spor 7,7'> som er parallelt anordnet i et plan over boringens 5 aksiale midtlinje. Disse spor 7*7' er hensiktsmessig uttatt på en slik måte at de er boret forst etterat boringen 5 er fremstilt. Hylsen 6, som hensiktsmessig er fremstilt av kunstplast eller liknende materiale, er på sin utside utformet med to aksialt rettede vulster 8,8', som danner styre- og bæreorganer. Dessuten er hylsen 6 på sin utside utformet med en ring-formet krage 9, hvis ytterkant er innrettet til å ligge an mot utsiden av pipehodet 1. Vulstene 8,8' er således plassert at de passer inn i sporene 7,7'» når hylsen 6 er innfort i boringen 5. Hylsens 6 tversnittsareal er noe mindre enn boringens 5 tversnittsareal, idet vulstene 8,8' er plassert på en slik måte at hylsen 6 med sin ovre del ligger ån mot boringens 5 vegg, mens hylsen 6 In the wall of the borehole 5, two grooves 7.7'' running in its longitudinal direction are taken out, which are arranged in parallel in a plane above the axial centerline of the borehole 5. These grooves 7*7' are expediently taken out in such a way that they are drilled only after the bore 5 has been made. The sleeve 6, which is suitably made of plastic or similar material, is designed on its outside with two axially directed beads 8,8', which form control and support members. In addition, the sleeve 6 is designed on its outside with a ring-shaped collar 9, the outer edge of which is arranged to rest against the outside of the pipe head 1. The beads 8,8' are positioned so that they fit into the grooves 7,7'" when the sleeve 6 is inserted into the bore 5. The cross-sectional area of the sleeve 6 is somewhat smaller than the cross-sectional area of the bore 5, as the beads 8,8' are positioned in such a way that the sleeve 6 with its upper part lies flush against the wall of the bore 5, while the sleeve 6

ved sin nedre del ikke ligger direkte an mot boringens 5 vegg. Vulstene 8,8' tjenestgjor herved som bæreorganer for avlastning at its lower part does not lie directly against the wall of the borehole 5. The beads 8.8' serve here as load bearing members

av det trykk som ellers skulle virke mot materialet i pipehodets 1 bunndel, f.eks. ved krymping eller svelling av materialet i pipehodet 1 samt ved brytevirkning mot pipemunnbittet 2 i forhold til pipehodet 1. Ved hylsens 6 og boringens 5 nedre deler dannes en spalte, som muliggjcir materialets krympings- eller svellingsbeveg-elser, uten at sprekkdannelse i pipehodets 1 tremateriale kan fore-komme. - of the pressure that would otherwise act against the material in the pipe head's 1 bottom part, e.g. by shrinking or swelling of the material in the pipe head 1 as well as by breaking action against the pipe mouthpiece 2 in relation to the pipe head 1. A gap is formed at the lower parts of the sleeve 6 and the bore 5, which enables the material to shrink or swell, without cracking in the wooden material of the pipe head 1 may occur. -

Trematerialet ved pipehodets 1 bunndel er The wood material at the 1 bottom part of the pipe head is

på grunn av utformningen samt boringen 5 relativt tynt og tåler due to the design and the bore 5 relatively thin and durable

derfor ingen storre spenningsbelastninger. Hvis trematerialet ved pipehodets bunndel utsettes for spenninger, oppstår det umiddelbart sprekker, som medforer at en del av trematerialet faller bort.Denne ulempe er helt eliminert ved anordningen ifolge oppfinnelsen, d.v.s. vulstene 8,8' avlaster alt trykk mot trematerialet, der dette er som svakest. Også ved tobakkspiper der pipehodet er fremstilt av annet materiale, f.eks. kunstplast eller liknende, oppnås den beskrevne avlastningseffekt. - therefore no major voltage loads. If the wooden material at the bottom part of the pipe head is exposed to tension, cracks immediately occur, which means that part of the wooden material falls away. This disadvantage is completely eliminated by the device according to the invention, i.e. the beads 8.8' relieve all pressure against the wooden material, where this is weakest. Also for tobacco pipes where the pipe head is made of other material, e.g. plastic or similar, the described relief effect is achieved. -

Hylsen er ved sin ene ende utformet med en bunn 6', hvorved fra glodekammeret 3 kommende olje eller liknende effektivt hindres fra å trenge inn mellom boringen 5 og hylsens 6 ytterside. Gjennom hylsens 6 vegg ved dens ovre del er anordnet en bossing 10, som med friksjon griper inn i rokkanalen 4» Denne bossing 10 tjener som lås eller sperre, i den hensikt å holde hylsen 6 i en fiksert fast stilling i boringen 5, hvorved den ringformete krages 9 ytterkant ligger stodig an og spenner mot pipehodets 1 ytterside, hvilket medforer den effekt at det dannes et ytre mottrykk mot den tynnere del av materialet i pipehodets bunndel, for opptag-else av eventuelt opptredénde spenningsbelastninger i materialet, f.eks. på grunn av utilsiktet kraftig bryte- eller slagvirkning mot dette. Kunstplastmaterialet i hylsen 6 er hensiktsmessig så smidig at kragens 9 ytterkant ligger fjærende an mot pipehodet 1 og derved danner et tett og tiltalende anlegg samt overgang. Kragen 9 er anordnet i en avstand fra hylsens 6 åpne ende, hvorved denne endedel danner en bossing 6", på hvilken munnbittet 2 kan anbringes forskyvbart og lostagbart. I hylsens åpne ende er med friksjon delvis inn-forbart et langstrakt filter 11, som i sin ene ende er utformet til å ligge an mot enden av en i munnbittet 2 utformet indre rokkanal 12, som ved dette endeparti er utstyrt med en eller flere gjennom kanal - veggen gående slisser 13>13'> som kan være vertikalt og/eller horison-talt rettet. Denne indre rokkanal 12 i forbindelse med nevnte slisser medforer den effekt at i filteret 11 absorbert olje, tjære eller liknende ikke kan komme inn i den indre rokkanal 12 og således sug-es inn i munnen, ettersom filteret avlastes fra sugevirkning, hvis det skulle ligge an mot rokkanalens 12 indre ende. - The sleeve is designed at one end with a bottom 6', whereby oil or the like coming from the glow chamber 3 is effectively prevented from penetrating between the bore 5 and the outer side of the sleeve 6. A boss 10 is arranged through the wall of the sleeve 6 at its upper part, which engages with friction in the rocker channel 4". This boss 10 serves as a lock or block, with the purpose of holding the sleeve 6 in a fixed fixed position in the bore 5, whereby the the ring-shaped collar's 9 outer edge lies firmly against and spans the outer side of the pipe head 1, which results in the effect that an external counter-pressure is formed against the thinner part of the material in the bottom part of the pipe head, for absorption of possibly occurring tension loads in the material, e.g. due to an unintentionally strong breaking or impact effect against it. The synthetic plastic material in the sleeve 6 is suitably flexible so that the outer edge of the collar 9 rests springily against the pipe head 1 and thereby forms a tight and attractive fit and transition. The collar 9 is arranged at a distance from the open end of the sleeve 6, whereby this end part forms a boss 6", on which the mouthpiece 2 can be placed displaceably and detachably. In the open end of the sleeve, an elongated filter 11 is partially inserted by friction, as in its one end is designed to rest against the end of an inner rook channel 12 formed in the mouthpiece 2, which at this end part is equipped with one or more slits 13>13'> running through the channel - the wall which can be vertical and/or horizontal This inner rock channel 12 in connection with the aforementioned slits has the effect that oil, tar or the like absorbed in the filter 11 cannot enter the inner rock channel 12 and thus be sucked into the mouth, as the filter is relieved from the suction effect, if it were to abut against the inner end of the rock channel 12. -

Det vesentlige ved oppfinnelsen er sporene 7,7' i forbindelse med styre- og bæreorganene 8,8', og denne anordning kan med fordel nyttes ved alle slags tobakkspiperj det være seg utforelser der hylsen utgjor en del av munnbittet eller er fast anordnet på dette, eller om munnbittet er forskyvbart eller fast anordnet på pipehodet. - The essential aspect of the invention is the grooves 7,7' in connection with the control and support members 8,8', and this device can be advantageously used with all kinds of tobacco pipes, be it designs where the sleeve forms part of the mouthpiece or is fixed on it , or whether the mouth piece is displaceable or fixed on the pipe head. -

Anordningen ifolge oppfinnelsen medforer også at for pipehoder bestemte emner, som er i hovedsaken vinkelformete og delvis er beheftet med feil i form av sprekker eller liknende, kan anvendes for fremstilling av pipehoder av den type som er vist og beskrevet, ettersom selve munnbitt-delen av emnene kan fjernes. Nye emner behover heller ikke være vinkelformete, hvor ved det spares store materialmengder. - The device according to the invention also means that blanks specified for pipe heads, which are mainly angular and partially affected by defects in the form of cracks or the like, can be used for the production of pipe heads of the type shown and described, as the actual mouth part of the topics can be removed. New items also do not need to be angular, which saves large amounts of material. -

Opjjfinnelsen er således ikke begrenset til den ovenfor beskrevne og på tegningen anskueliggjorte utforelsesform, men kan varieres og modifiseres på flere måter innenfor rammen for oppfinnelsestanken og etterfølgende patentkrav. - The invention is thus not limited to the embodiment described above and illustrated in the drawing, but can be varied and modified in several ways within the scope of the inventive idea and subsequent patent claims. -

Således kan hylsen 6 og kragen 9 være fremstilt i hver sin enhet, hvorved hylsen 6 er av stivt materiale og kragen er av forholdsvis mykt materiale. Av sporene 7 og 7<1> samt av styre- og bæreorganene 8,8' kan det selvfolgelig være anordnet flere enn to av hver sort, og de kan også ha annen form enn som vist og beskrevet. - Thus, the sleeve 6 and the collar 9 can be produced in separate units, whereby the sleeve 6 is of rigid material and the collar is of relatively soft material. Of the tracks 7 and 7<1> as well as of the control and support members 8, 8', more than two of each type may of course be arranged, and they may also have a different shape than shown and described. -
