Abstract

PennPen

Description

Oppfinnelsen gjelder en penn, som også kan romme et stempel eller en annen gjenstand. The invention relates to a pen, which can also accommodate a stamp or other object.

Formålet med oppfinnelsen har i første rekke vært å tilveiebringe en penn som på grunn av en hovedsakelig plan utforming skal være bekvem å ta med seg også i lomma på ei tynn skjorte, men som samtidig skal ha en gripedel med stort sett rundt tverrsnitt og et påvirkningsorgan for inntrekking av skrivestiften, som er plassert slik at man kan finne den med følesansen, dvs. uten at man ser på pennen. The purpose of the invention has primarily been to provide a pen which, due to a mainly flat design, should be convenient to take with you even in the pocket of a thin shirt, but which should at the same time have a grip part with a largely round cross-section and an impact device for retraction of the stylus, which is positioned so that it can be found with the sense of touch, i.e. without looking at the pen.

Det har dessuten vært et ønske å oppnå en meget enkel konstruksjon og redusere risikoen for skrivetretthet ved å by hånden alternative gripemuligheter. Oppfinnelsen har også tatt sikte på å utforme pennen slik at den skal kunne innehol-de eller romme en fortrinnsvis sammenfellbar nyttegjenstand, f.eks. et stempel som skal kunne tas ut av pennen ved å påvir-ke et sperreorgan e.l. There has also been a desire to achieve a very simple construction and reduce the risk of typing fatigue by offering the hand alternative grip options. The invention has also aimed at designing the pen so that it should be able to contain or accommodate a preferably collapsible utility object, e.g. a piston which must be able to be removed from the pen by influencing a locking device or the like.

Dette er oppnådd ved at pennen i samsvar med de karakteristiske trekk som framgår av etterfølgende patentkrav. This has been achieved by the pen in accordance with the characteristic features that appear in subsequent patent claims.

En utførelsesform for oppfinnelsen er vist på medfølgende tegning, hvor An embodiment of the invention is shown in the accompanying drawing, where

fig. 1 viser et lengdesnitt gjennom en penn somfig. 1 shows a longitudinal section through a pen which

fig. 3 et perspektivriss av "stempel-pennens" stempeldel, som her er tatt ut av pennen og vist i virksom stilling, og fig. 4 pennhylsa sett fra enden. fig. 3 is a perspective view of the piston part of the "piston pen", which is here taken out of the pen and shown in active position, and fig. 4 pen sleeve seen from the end.

Pennen ifølge oppfinnelsen er på tegningen illu-strert i form av en stempel-penn med ei pennhylse som generelt er betegnet med 1. I sin øvre del har pennhylsa stort sett rektangulært tverrsnitt. Denne rektangulære del er i fig. 4 be tegnet med 2. Pennhylsas nedre del 3 har stort sett rundt tverrsnitt, slik det også framgår av fig. 4. På grunn av at den runde delen har en største diameter som stort sett svarer tij. den rektangulære delens smaleste parti, innses det at man på denne måten får ei hylse som er meget smidig å benytte fordi diameteren ikke trenger å overstige ca. 9 mm, hvilket jo er mindre enn den hendigste penn. Pennhylsas øvre del har et før-ste hulrom 4 med stort sett rektangulært tverrsnitt og et andre hulrom 5 med sirkulært tverrsnitt. Dessuten har pennhylsa en øvre åpning 6 og en nedre åpning 7 som tjener et formål som vil bli beskrevet senere. The pen according to the invention is illustrated in the drawing in the form of a piston pen with a pen sleeve which is generally denoted by 1. In its upper part, the pen sleeve has a largely rectangular cross-section. This rectangular part is in fig. 4 be marked with 2. The pen sleeve's lower part 3 has a largely round cross-section, as can also be seen from fig. 4. Due to the fact that the round part has a largest diameter which largely corresponds to tij. the narrowest part of the rectangular part, it is realized that in this way you get a sleeve that is very flexible to use because the diameter does not need to exceed approx. 9 mm, which is smaller than the most handy pen. The upper part of the pen sleeve has a first cavity 4 with a largely rectangular cross-section and a second cavity 5 with a circular cross-section. In addition, the pen sleeve has an upper opening 6 and a lower opening 7 which serves a purpose which will be described later.

Stempelpennen omfatter en stempeldel, som generelt er betegnet med 8 og som består av et skaft 9 med en fjærende tunge 10 eom ender i en sperreknast 11*Sperretungen og -knasten er fortrinnsvis utformet i ett stykke med skaftet for-øvrig og dette er i likhet med stempelholderen og pennhylsa samt et glidelegeme, som vil bli beskrevet i det følgende, fortrinnsvis framstilt av passende plastmateriale, f.eks. acetal-plast for i det minste skaftet og glidelegemet. Stempelskaftet er beregnet til å være svingbart forbundet med en stempelhold-er og for dette formål er skaftet ved den viste utførelsesfor-men forsynt med to forlengete sidepartier 12, som danner fjærende greiner og som er utformet med lagerhull 13. I skaftet er det dessuten utformet en utsparing 14 som tjener et formål som angis senere. The piston pen comprises a piston part, which is generally denoted by 8 and which consists of a shaft 9 with a springy tongue 10 that ends in a detent cam 11* The detent tongue and cam are preferably designed in one piece with the rest of the shaft and this is similar with the stamp holder and pen sleeve as well as a sliding body, which will be described in the following, preferably made of suitable plastic material, e.g. acetal plastic for at least the shaft and slide body. The piston shaft is designed to be pivotably connected to a piston holder and for this purpose, in the embodiment shown, the shaft is provided with two extended side parts 12, which form springy branches and which are designed with bearing holes 13. In the shaft, there is also designed a recess 14 which serves a purpose which will be stated later.

Den forannevnte stempelholderen 16 har stort sett rektangulær form og er forsynt med to lagertapper 17, som er beregnet til å samvirke med hullene 13 i skaftet 9 for å forbinde delene svingbart med hverandre. Det er anordnet orga-ner for å låse skaftet og stempelholderen i den virksomme stillingen ifølge fig. 3 og fortrinnsvis også i den sammenlagte stillingen som vises i fig. 1 og 2. På grunn av at sidepartiene 12 er utformet fjærende, er det lett å forbinde holderen med skaftet, nemlig ved å bøye sidepartiene litt ut fra hverandre samtidig som holderen bringes i en slik stilling at tappene 17 kan gripe inn i hyllene 13. Ved å utforme holderens kantpartier med utsparinger 18, som sidepartiene 12 presses inn i når stempelet befinner seg i den stilling som er vist i fig. 3, vil det oppnås låsing i denne stillingen, men ved å utforme grenene 12 med fortykkete, hovedsakelig kvadratiske endeparti-er 19 oppnås det låsing av skaftet i forhold til holderen i begge endestillingene. The aforementioned piston holder 16 has a largely rectangular shape and is provided with two bearing pins 17, which are intended to cooperate with the holes 13 in the shaft 9 to connect the parts pivotably with each other. Means are arranged to lock the shaft and the piston holder in the effective position according to fig. 3 and preferably also in the folded position shown in fig. 1 and 2. Because the side parts 12 are designed to be springy, it is easy to connect the holder to the shaft, namely by bending the side parts slightly apart from each other while bringing the holder into such a position that the pins 17 can engage the shelves 13. By designing the edge parts of the holder with recesses 18, into which the side parts 12 are pressed when the piston is in the position shown in fig. 3, locking will be achieved in this position, but by designing the branches 12 with thickened, mainly square end parts 19, locking of the shaft in relation to the holder in both end positions is achieved.

Stempelholderen har form av en åpen kasse hvori det er innpasset en stempelplate 18 av såkalt mikroporøst ma-teriale, som dessuten er elastisk sammentrykkbart. Slike mikro-porøse gummiplater kan oppta stempelfarge og ved avtrykk også avgi denne på en slik måte at det kan oppnås 10.000-talls avtrykk med en eneste fylling. Materialet er dessuten av en slik beskaffenhet at stempelfargen ikke tørker inn under luftens innvirkning. The piston holder has the form of an open box into which a piston plate 18 of so-called microporous material, which is also elastically compressible, is fitted. Such micro-porous rubber sheets can absorb stamp ink and, when printed, also emit this in such a way that 10,000 prints can be obtained with a single filling. The material is also of such a nature that the stamp color does not dry out under the influence of air.

Pennen omfatter også et glidelegeme, som generelt er betegnet med 20. Dette har i likhet med skaftdelen 9 en fjærende tunge 21 som ender i en sperreknast 22. I likhet med sperretungen 10 er sperretungen 21 innfestet i sin på figuren, nedre ende, slik at sperrevirkningen forsterkes ved økende be-lastning, fordi det dreiemoment som virker på sperreknasten søker å svinge tungen i en retning som øker inngrepet. Glidelegemet er dessuten forsynt med en styring 23 for å holde en kulespisspatron 24 eller et annet skriveorgan fast ved frik-sjonsvirkning. Styringen består fortrinnsvis av en utsparing med noe innadrettete vulster, slik at patronen kan presses inn i utsparingen fra siden. For å begrense svingebevegelsen for sperretungen 21, er sperreknasten utformet med et slde-rettet framspring 25. The pen also includes a sliding body, which is generally denoted by 20. Like the shaft part 9, this has a spring-loaded tongue 21 which ends in a locking cam 22. Like the locking tongue 10, the locking tongue 21 is attached to its lower end in the figure, so that the locking effect is strengthened with increasing load, because the torque acting on the locking cam seeks to swing the tongue in a direction that increases the engagement. The sliding body is also provided with a guide 23 to hold a ballpoint cartridge 24 or another writing device firmly by friction. The control preferably consists of a recess with somewhat inwardly aligned beads, so that the cartridge can be pressed into the recess from the side. In order to limit the swinging movement of the locking tongue 21, the locking cam is designed with a slide-directed projection 25.

Ei skruefjær 2$, som med sin ene ende har anlegg mot en ansats i pennhylsa og står i friksjonsinngrep med denne, støter med sin andre ende mot en flens på kulespisspatronen eller mot glidelegemet i mangel av en slik flens og står også A coil spring 2$, which has one end against a shoulder in the pen sleeve and is in frictional engagement with this, with its other end abuts against a flange on the ballpoint cartridge or against the sliding body in the absence of such a flange and also stands

i friksjonsinngrep med patronen og/eller glidelegemet.in frictional engagement with the cartridge and/or the sliding body.

Pennen virker på følgende måte:The pen works in the following way:

Når man ønsker å benytte pennen, utøver man bare et trykk på den del av skaftet som rager ut av pennhylsa. Det framgår av fig. 1 og 2 at denne utragende del tjener som knapp for å føre skrivepatronen henholdsvis til og ut av arbeids-stilling. Fra en stilling hvor glidelegemet forskyves nedover, hvorved dets sperreknast 22 kommer i sperrende inngrep med åpningen 7. Derved låses skrivepatronen i sin virksomme stilling, When you want to use the pen, you only apply pressure on the part of the shaft that protrudes from the pen sleeve. It is clear from fig. 1 and 2 that this projecting part serves as a button to move the print cartridge into and out of the working position respectively. From a position where the sliding body is displaced downwards, whereby its locking cam 22 comes into locking engagement with the opening 7. Thereby the writing cartridge is locked in its active position,

som er vist i fig. 1 og 2.which is shown in fig. 1 and 2.

Når man ønsker å benytte stemplet, griper man om skaftdelen samtidig som man med fingeren trykker sperreknasten 11 inn i pennhylsa. Skaftdelen kan nå trekkes utover. Det anvendelsesklare stempel taa deretter ut av pennhylsa. På grunn av at-stempelplaten eller -puten er innfarget på den beskrevne måten, kan det utføres et ønsket antall stempelavtrykk etter hverandre. Samtidig er skrivepatronen i bruksstilling, When you want to use the stamp, you grasp the shaft part at the same time as you press the locking cam 11 into the pen sleeve with your finger. The shaft part can now be pulled out. The ready-to-use stamp is then taken out of the pen sleeve. Because the stamp plate or pad is inked in the manner described, a desired number of stamp impressions can be made one after the other. At the same time, the print cartridge is in use position,

og pennen kan benyttes helt uavhengig av stemplet. Etter at stemplingen er utført, skjer operasjonen i omvendt rekkefølge. and the pen can be used completely independently of the stamp. After the stamping is done, the operation takes place in reverse order.

For å bringe skrivepatronen i uvirksom stilling, er det selvfølgelig tilstrekkelig å trykke inn sperreknasten 22. Fjæren 26 vil da føre glidelegemet og dermed skrivepatronen oppover inntil skaftdelens sperreknast 11 går i inngrep med åpningen 6. To bring the writing cartridge into an inactive position, it is of course sufficient to press in the locking cam 22. The spring 26 will then move the sliding body and thus the writing cartridge upwards until the locking cam 11 of the shaft part engages with the opening 6.

Det vil forstås at det bare er den nedre åpningen 7 som benyttes når skrivespissen skal trekkes inn i pennhylsa, It will be understood that only the lower opening 7 is used when the writing tip is to be drawn into the pen sleeve,

og da denne ligger lett tilgjengelig i overgangen, mellom pennens bredeste og smaleste del, kan skrivespissen trekkes inn i pennhylsa selvom man ikke ser på pennen. and as this is easily accessible in the transition, between the pen's widest and narrowest part, the writing tip can be pulled into the pen sleeve even if you are not looking at the pen.

Det har vist seg at den beskrevne pennen gir høyst betydelige fordeler fra et skrivemessig synspunkt. Den sann-synlige forklaringen på dette er at pennhylsa på grunn av sin asymmetriske form får forskjellig balanse alt etter som pennen gripes, dvs. om pennen f.eks. gripes slik at den i fig. 2 venstre delen av pennens bredeste del vender oppover, henholdsvis om pennen holdes slik at nevnte del vender nedover, henholdsvis mellomstillinger. Ved å skifte grep om pennen med hånden mot-virkes skrivetretthet på en effektiv måte, og den smidige for-men gjør pennen meget lett å skrive med. It has been found that the described pen offers very significant advantages from a writing point of view. The most likely explanation for this is that, due to its asymmetric shape, the pen sleeve has a different balance depending on how the pen is gripped, i.e. if the pen e.g. is grasped so that it in fig. 2 the left part of the pen's widest part faces upwards, respectively if the pen is held so that said part faces downwards, respectively intermediate positions. By changing the grip on the pen with your hand, writing fatigue is effectively counteracted, and the flexible design makes the pen very easy to write with.

De deler av stempelplaten som skal etterlate stempelavtrykk må selvsagt rage ut til et plan som i stemplets bruksstilling ligger nedenfor stempelholderéns nedre plan, og disse deler vil på den måten kunne komme i kontakt med pennhylsas indre. For å unngå dette er grenene 12, fig. 1, så bre-de at stempelflaten ifølge denne tegningsfigur befinner seg i et plan som befinner seg til venstre for et plan gjennom grenenes høyre kantpartier. The parts of the stamp plate which are to leave a stamp impression must naturally project to a plane which, in the stamp's position of use, lies below the lower plane of the stamp holder, and these parts will thus be able to come into contact with the interior of the pen sleeve. To avoid this, the branches 12, fig. 1, they are so wide that the piston surface according to this drawing figure is located in a plane which is located to the left of a plane through the right edge parts of the branches.

For å beskytte stempelplaten er det ifølge fig. 3 festet en fjærende tunge 30 til stempelstangen. På grunn av tungens elastiske utforming svinges denne ut og danner en fjærende støtte når stempelholderen ifølge fig. 3 svinges ut til stemplingsstilling. In order to protect the piston plate, according to fig. 3 attached a resilient tongue 30 to the piston rod. Due to the elastic design of the tongue, it swings out and forms a resilient support when the piston holder according to fig. 3 is swung out to the stamping position.

Den beskrevne pennen er som nevnt svært enkel å framstille og bruke, men for at pennen skal fungere etter hen-sikten er det et krav at skrivepatronen ikke utilsiktet kan følge med stemplet ut av pennhylsa. Dette oppnås ved at fjæra 26 som nevnt er friksjonskoblet til såvel glidelegemet eller skrivepatronen som pennhylsa. Man må derfor med en gjenstand, f.eks. en ny patron, som stikkes inn gjennom åpningen 7, fri-gjøre enheten glidelegeme 20, fjær 26 og patron 24 fra pennhylsa for å kunne ta ut denne. Det kan også tenkes andre løs-ninger på dette problem. As mentioned, the described pen is very easy to produce and use, but in order for the pen to function as intended, it is a requirement that the writing cartridge cannot accidentally follow the stamp out of the pen sleeve. This is achieved by the fact that the spring 26, as mentioned, is frictionally connected to both the sliding body or the writing cartridge as well as the pen sleeve. One must therefore with an object, e.g. a new cartridge, which is inserted through the opening 7, release the unit sliding body 20, spring 26 and cartridge 24 from the pen sleeve to be able to take it out. Other solutions to this problem can also be thought of.

I de tilfeller der pennen ikke er kombinert med et stempel eller liknende er glidelegemet forlenget slik at det omfatter også den fjærende tungen 10, 11 og en del som rager ut av pennhylsas øvre ende ifølge figuren. En slik penn består således foruten ei fjær, og en kulespisspatron bare to deler, nemlig hylsa 1 og det nettopp beskrevne forlengete glidelegemet. In those cases where the pen is not combined with a piston or the like, the sliding body is extended so that it also includes the springy tongue 10, 11 and a part that protrudes from the upper end of the pen sleeve according to the figure. Such a pen thus consists, in addition to a spring, and a ballpoint cartridge only two parts, namely the sleeve 1 and the just-described elongated sliding body.
