Vid dubbelkikare har hittills anvants tvâ olika anordningar for skarpinstallning. Den ena utgores av indivuell installning fOr yardera okularet. Denna anordning är emellertid obekvam vid anvandningen, enar hada okularen skola omstallas lika myeket vid varje stiirre andring av aystandet till malet. Den andra anordningen pledger en installning av bada okularen samtidigt. En anordning harfor är utford pa fOljande satt. Dubbelkikaren bestar av tva enkelkikare, som aro lagrade ph en gemensam axel, parallell med kikarens optiska axlar, yarigenom okularavstandet kan anpassas efter betraktarens ogonaystand. Okularen Oro darvid fastade yid tva armar, lagrade ph en skruv, som liar axeln sammanfallande med oyannamnda yridningsaxel for hela kikarna. Denna skruy forskjutes i sin langdriktning med hjalp av en mutter. Genom yridning ay denna mutter forskjutes daryid hada okularen lika mycket. Darjamte kan det ena okularet vara individuellt installbart. In the case of double binoculars, two different devices for sharp installation have so far been used. One consists of individual installation for the yard of the eyepiece. However, this device is inconvenient to use, as the eyepiece should be repositioned just as much with each major change of the condition to the grind. The second device provides an installation of both eyepieces simultaneously. A device for this is a challenge in the following way. The double binoculars consist of two single binoculars, which are mounted on a common axis, parallel to the optical axes of the binoculars, so that the eyepiece distance can be adapted to the viewer's eye position. The eyepiece Oro thereby fastened yid two arms, ph stored a screw, which liar the shaft coincides with the aforementioned riding axis for the whole binoculars. This screw is displaced in its longitudinal direction with the help of a nut. By dripping on this nut, the daryid had the eyepiece shifted just as much. In addition, one eyepiece can be individually installed.

Vid det sistnamnda utforandet kommer kikaren att bli relativt otat, enar okularen maste kunna glida axiellt pa var sin hylsa. Darjamte forefinnes star risk for att okularen efter en tids anvandning ej langre Oro parallella med varandra, vilket i hog grad trattar ogonen eller rent av omojliggiir for betraktaren att bringa samman de tva bilder, som astadkommas av ogonen till en bild. In the latter embodiment, the binoculars will be relatively unobtrusive, one eyepiece must be able to slide axially on each sleeve. Furthermore, there is a risk that the eyepiece, after a period of use, will no longer be parallel to each other, which greatly distorts the eyes or even makes it impossible for the viewer to bring together the two images produced by the eyes into one image.

Genom foreliggande uppfinning mOjliggores konstruktionen av en dubbelkikare, yid vilken okularen kunna installas dels var far sig, dels hada samtidigt, och vid vilken ovannamnda olagenheter Oro eliminerade. Uppfinningen kannetecknas framfOr alit darigenom, att okularen aro fastade yid var sin gangade hylsa. Dessa hylsor ha gangingrepp med och Oro lampligen inpassade i andra gangade hylsor, fastade vid var sin kikarstomme. Okularhylsorna Oro forbundna med varandra med hjalp av en transmission, innehallande en franslagbar koppling. Transmissionen kan besta ay ett antal kugghjul, ay vilka ett Or axiellt forskjutbart far att astadkomma urkoppling ay forbindelsen mellan okularen och darigenom bildar den franslagbara kopplingen. Uppfinningen fortydligas i det fOljande genom ,ett par som exempel valda utforingsformer. The present invention enables the construction of a double binoculars, in which the eyepiece can be installed partly separately, partly simultaneously, and at which the above-mentioned malfunctions Oro eliminated. The invention can be characterized in particular by the fact that the eyepiece is attached to each of its threaded sleeves. These sleeves have a gangway engagement with and Oro aptly fitted into other threaded sleeves, each attached to a binocular frame. The eyepiece sleeves are connected to each other by means of a transmission, containing a frangible coupling. The transmission may consist of a number of gears, in which an axially displaceable one causes the disengagement of the connection between the eyepiece and thereby forms the disengageable coupling. The invention is elucidated in the following genome, a pair of exemplary embodiments.

Fig. 1 yisar ett utforande av en kikare enligt uppfinningen, sedd fran okularsidan, medan fig. 2 visar samma kikare i ett haremot vinkelratt plan, delyis i genomskarning efter linjen A—A i fig. 1. Fig. 3 yisar en variant ay den konstruktiya utformningen. Fig. 1 shows an embodiment of a pair of binoculars according to the invention, seen from the eyepiece side, while Fig. 2 shows the same pair of binoculars in a perpendicular plane, delyis in section along the line A-A in Fig. 1. Fig. 3 shows a variant of the konstruktiya design.

I fig. 1 och 2 betecknar 1 ett okular, fast vid en hylsa 2, soul. Or gangad pa en andra hylsa 3, fast yid en kikarstomme 4. Vid hylsan 2 Or en som medbringare yerkande delvis uppskuren hylsa 5 fast. Hylsan 5 samverkar med en andra uppskuren hylsa 6, som Or lagrad pa hylsan 3, vilken samyerkan Or sadan, att medbringaren oyerfor yridningsriirelse och samtidigt medgiver axiell forskjutning av okularen relativt kikarestommen. Hylsan 6 Or i sin mot kikarstommen Yanda del utfOrd med en kuggkrans 6', som samverkar med ett mellankugghjul 7, lagrat pa en tapp, fast vid kikarstommen 4. De tya kikarstommarna 4 Oro hada lagrade pa en axel 8. Ph axeln 8 Or ett kugghjul 9 lagrat, som kan samverka med de tva mellanhjulen 7. Kugghjulet 9 Or axiellt forskjutbart och Mlles tryekt mot sift ena andlage av en skruvfjfider 10. Rorelsen i denna riktning sparras av en vid axeln 8 fast andplatta 11. I andplattan 11 Or en klack 12 fast, som i ett loge ay kugghjulet 9 kan glida in i en motsvarande urtagning ph detsamma. Hela overforingsanordningen tackes av tva kapor 13, en for vardera kikarhalvan. Dessa kapor Oro anordnade sa, att. de kunna passera varandra for att medge kikarhalvornas yridning i farhallande till varandra for uppnaende ay onskat okularaystand. In Figs. 1 and 2, 1 denotes an eyepiece, attached to a sleeve 2, soul. Attached to a second sleeve 3, fixed to a binocular frame 4. Attached to the sleeve 2 is a partially cut-out sleeve 5 attached as a carrier. The sleeve 5 cooperates with a second cut-out sleeve 6, which is mounted on the sleeve 3, which co-operates in such a way that the carrier is free of sliding movement and at the same time allows axial displacement of the eyepiece relative to the binocular body. The sleeve 6 Or in its anti-binocular frame Yanda part is made with a gear ring 6 ', which cooperates with an intermediate gear wheel 7, mounted on a pin, fixed to the binocular frame 4. The ten binocular frames 4 Oro had mounted on a shaft 8. Ph shaft 8 Or a gear 9 stored, which can cooperate with the two intermediate wheels 7. The gear 9 is axially displaceable and Mlles pressed against the sieve one end of a screw spring 10. The movement in this direction is blocked by a duct plate fixed at the shaft 8. In the duct plate 11 Or a lug 12 fixed, which in a lodge ay the gear 9 can slide into a corresponding recess ph the same. The entire transfer device is thanked by two caps 13, one for each binocular half. These capers Oro organized said, that. they can pass each other to allow the binocular halves to move in relation to each other to achieve the desired ocular position.

I fig. 3 visas en variant av anordningen enligt fig. 1 och 2. I denna figur beteckna 1-4 och 7 samma detaljer som i fig. 1 och 2. Hylsan 2 Or emellertid har utformad med en kuggkrans, som samverkar med kugghjulet 7. Pa grund ay hylsans 2 forskjutning i axial-led yid dess yridning maste emellertid anting- 2— en kuggkransen pa hylsan 2 eller kugghjulet 7 goras sa lang i axialled, att ingreppet Yidmakthalles yid alla ifragakommande Harigenom kan den medbringare, som bildats av hylsorna 5 och 6 i fig. 2 undvaras. Fig. 3 shows a variant of the device according to Figs. 1 and 2. In this figure 1-4 and 7 denote the same details as in Figs. 1 and 2. However, the sleeve 2 Or has been formed with a gear ring which cooperates with the gear wheel 7. However, due to the displacement of the sleeve 2 in the axial direction during its rotation, either the gear ring on the sleeve 2 or the gear 7 must be made so long in the axial direction that the engagement of the sleeve in all of them can thereby carry the carrier formed by the sleeves. and 6 in Fig. 2 are dispensed with.

Yid installning av en kikare, utford enligt uppfinningen, frikopplas forst de hi, installningsanordningarna genom nedtryckning ay kugghjulet 9 och -vridning, sã att klacken 12 ej ligger mitt for urtagningen i kugghjulet 9. Darefter installes okularavstandet sa, att det sammanfaller med betraktarens agonavstand. Sedan detta skett, installas de tva okularen var for sig, sa att ett och samma foremal synes skarpt for hada ogonen. Darefter hopkopplas de tva okularinstallningarna, genom att kugghjulet 9 yrides tillbaka till det Ifige, dar tappen 12 glider in i urtagningen pa kugghjulet 9, Yarvid skruyfjadern 10 trycker upp kugghjulet 9, sa att ingrepp erhalles med de tva kugghjulen 7 vid omstallning av avstandsinstallningen for kikaren genom vridning av endera ay hylsorna 2 eller kugghjulet 9. Darvid vrides de tva okularen alltid lika mycket, varfor samma person hela tiden far skarpa bilder far hada ogonen. When installing a pair of binoculars, according to the invention, the mounting devices are first disengaged by depressing the gear 9 and rotating them so that the lug 12 is not in the middle of the recess in the gear 9. Then the eyepiece distance is installed so that it coincides with the viewer's agon distance. After this has been done, the two eyepieces are installed separately, so that one and the same object seems sharp to the eyes. Then the two eyepiece installations are connected, by rotating the gear 9 back to the Ifige, where the pin 12 slides into the recess on the gear 9, while the coil spring 10 pushes up the gear 9, so that engagement is obtained with the two gears 7 when adjusting the spacer. by turning either the sockets 2 or the gear 9. In this case, the two eyepieces are always rotated the same amount, which is why the same person always gets sharp images from the eyes.

Avvikelser frau de yisade utforingsformerna kunna farekomma i flera avseenden inom ramen for uppfinningen. SA till exempel kunna andra transmissioner an kugghjulstransmissioner anordnas mellan okularhylsorna, till exempel kedjetransmissioner, varyid exempelvis kugghjulet 9 ersattes med tva lampligen koaxiella kedjehjul, som kunna hada samtidigt eller var for sig hopkopplas med samma axel medelst en for hand utlosbar spdrr eller dylikt. Darvid kan lampligen det ena av de koxaiella kedjehjulen yarn forenat med det ena okularet och det andra kedjehjulet med det andra okularet. Deviations from the modified embodiments can be dangerous in several respects within the scope of the invention. SA, for example, other transmissions than gear transmissions can be arranged between the eyepiece sleeves, for example chain transmissions, for example the gear 9 is replaced by two suitably coaxial sprockets, which can have simultaneously or separately coupled to the same shaft by means of a manually releasable track or the like. Thereby, suitably, one of the coaxial sprockets may be joined to one eyepiece and the other sprocket to the other eyepiece.
