    The invention relates to an adapter sleeve for a observation tube according to the preamble of claim 1, a fastening adapter according to the preamble of claim 17, an adapter system according to the preamble of claim 18 and an eyepiece assembly according to the preamble of claim 19.
    Observation tubes are often used not only for direct observation but often also the optical image produced by a mounted on the eyepiece of an observation telescope further optical recording or measuring device and processed. For example, in addition to direct observation, images of the observed scene are often recorded in nature observations, and this may require multiple mounting and dismounting of a camera on the observation tube. To facilitate this, special brackets have been developed with which a camera can be mounted and dismounted quickly and without tools on the observation tube, at the same time a high positioning accuracy is to be achieved in order to avoid aberrations due to mismatch of the optical axes.
    Corresponding brackets must ensure an exact fit both on the observation telescope and on the recording device or measuring device, and such brackets must be suitable for the types used in each case. In order not to need a complete own bracket for each combination of different observation tubes and recording devices, it is known to attach holders that are suitable for a specific recording device, not directly to an eyepiece, but by means of a mounted on the eyepiece adapter. Such a holder corresponds for example to the digital camera N2011 / 29300 11/06/2012 16:40

The adapter sleeve to be fastened to the eyepiece, in which a radially acting clamping screw is arranged, has a significantly larger diameter than the eyepiece itself and can impair the handiness of the observation tube.
    In the course of further development of the optical imaging quality both in observation telescopes and recording or measuring devices, the requirements for accuracy in the positioning of the mounting of recording and measuring devices or accessories generally increase in such holders. At the same time, such holders should be adaptable to different devices to be connected by suitable adapters. The disadvantage here is further that eyepiece sections are often not designed for the subsequent attachment of accessories or adapter sleeves due to their shape or their mechanical strength and therefore this is problematic, especially if it is trying ~ uifpassende or unsuitable brackets to assemble.
    The object of the invention is to provide an adapter sleeve or eyepiece assembly with an adapter sleeve, which is also suitable for increased demands on the positioning accuracy and at the same time is inexpensive to produce. Furthermore, the adapter sleeve should provide an improvement in the case of a model change in the observation tube or the optical recording or measuring device.
    The object of the invention is achieved by a generic adapter sleeve with the characterizing features of claim 1 and a fastening adapter equipped therewith with the features of claim 17
    Due to the fact that the outer centering surface comprises at least two outer centering sections each having a constant outer diameter, wherein the outer diameters of the outer centering sections increase in the direction of observation, several advantageous effects can be achieved. The following remarks apply equally to the terms accessory and bracket. N2011 / 29300 11/06/2012 16:41

    The multiple Außenzentrierabschnitte with different outer diameters result in combination with a correspondingly shaped holder a higher positioning accuracy, as each radial clearance fits result at the individual stages, and the largest existing clearance is reduced by a smaller clearance of other stages, which in an Außenumfangsflä-che with a single constant outside diameter is not the case, but here the only and at the same time the largest radial clearance is effective. If it is assumed that in the manufacture of the adapter sleeve according to the invention, the same Fertigungstoferanzen be achieved as in known embodiments, the positioning accuracy of a holder can be increased with little effort by this measure.
    Furthermore, this somewhat stepped shape of the outer surface allows easier axial sliding of a holder adapted to this shape of an adapter sleeve, since the outer diameter of the observer-side first outer centering section is smaller than the outer centering section or sections following in the viewing direction.
    In addition, such a shaping of the outer surface stimulates a corresponding shaping of the holder, so that optimal optimal centering over the largest possible length is possible on the interface formed thereby. The use of unsuitable embodiments of holders can be prevented, for example, the adapter sleeve or the mechanically overloaded by the adapter sleeve eyepiece section could, for example by using unsuitable fasteners. The special shape of the adapter sleeve thus complicates the attachment of unsuitable brackets.
    By having the outer centering sections each having a constant outer diameter, it is possible with a suitable embodiment of the fastening means on the support to adjust the accessory in the axial direction and to fix it in different positions. N2011 / 29300 11/06/2012 16:42

    An advantageous embodiment of the adapter sleeve is that the outer diameter increases from one outer centering section to the next outer centering section by a value between 1% and 10%. For example, in an advantageous embodiment, the diameter of the first outer centering section is e.g. 62 mm while the diameter of the second Außenzentrierabschnittes 63 mm is also by such a small gradation, the advantageous effects described above can be achieved and at the same time can be used with low Materiatstärken, whereby the handling of the observation telescope barely changed by the AdapterhOlse.
    In a further embodiment, the fastening section can be arranged between two outer centering sections which are distanced from one another in the direction of observation. The holder can thereby be supported on both sides of the attachment portion on Außenzentrierabschnitlen, whereby possible misalignments of Hafferurig aüfgrunid the existing Spieipassungen and the acting exerted by the fastening means clamping forces are reduced.
    In this case, the fastening section can have an outer diameter which is reduced in relation to the outer centering sections and can be formed in the form of a recess, groove or groove extending over the entire outer circumference of the adapter sleeve. Such an attachment portion may also be referred to as an intermediate portion and may engage therein a fastener of the accessory and thereby provide a full axial position assurance of the accessory. Furthermore, it is thereby possible with a somewhat loosened fastener to turn the accessory around the optical axis, without changing the axial position.
    Since a full-surface concerns of the adapter sleeve with minimal tolerances on Okularabschnittfertigungstechnisch not always easy to achieve, the centering function can be reduced to smaller areas where compliance with a high manufacturing accuracy is easier. The outer centering surface may for this purpose comprise at least two outer centering sections distanced from each other by a reduced-diameter intermediate section. The distancing N2011 / 29300 11/06/2012 16:43

    In order to enable the use of flat fasteners of the holder, without significantly increasing the overall length of the adapter sleeve, it is advantageous if the depression in the direction of observation has an extension between 5 mm and 12 mm.
    If the outer centering surface and / or the attachment portion of the outer surface is arranged at least partially after the fixing device, as seen in the viewing direction, the effects of a clearance fit between the eyepiece portion and the adapter sleeve and between the adapter sleeve and an accessory are reduced and thus the positional accuracy As a result, structurally simple fixing devices can nevertheless be used, which also provides the greatest possible flexibility in the design of the accessories to be attached to the adapter sleeve. Further, by the spatial distribution of the functions of fixing the adapter sleeve and fastening or centering the accessory, the overall diameter of the adapter HQIse and its Overall dimensions are kept small overall. The fixing device can exert fastening forces in the radial and / or axial direction on the eyepiece, which can be further reinforced by Be-fastening forces of the accessory.
    The compensation of possible minimum misalignments of the adapter sleeve and the accessory is further enhanced if the outer centering surface and / or the attachment portion of the outer surface is arranged in the direction of observation entirely after the fixing device. As a result, over the length of the adapter sleeve is considered a functional structure in fixing the adapter sleeve and attachment of the accessory, whereby the respective sections can each be optimally adapted to the functions to be fulfilled.
    The aforesaid advantages can be achieved despite a short overall length of the adapter sleeve, if the fixing device in the observer side end N2011 / 29300 11/06/2012 16:44

    A high repeat accuracy in the axial positioning of an accessory on the eyepiece can be achieved if the outer surface of the adapter sleeve aulweist a radially outwardly projecting stop element for the accessory, in particular in the form of an outer collar on the lens-side end portion of the adapter sleeve aulweist. Furthermore, collisions between the eyepiece portion and the optical accessory can be prevented because the path of the accessory is limited by the stopper.
    It can also be advantageous if one of the outer centering sections is preceded in the direction of observation by a transition section with a conically increasing outer diameter, whereby no sharp step is present in front of this outer centering section and the holder is pushed open.
    When the attachment portion on the outer surface coincides with an inner centering surface on the inner surface, the adapter sleeve is supported in this area by the eyepiece portion from the inside, and the attachment portion can accommodate high attachment forces despite thin wall thickness, since they are also discharged into the eyepiece.
    A forwarding of the fastening part exerted by the accessory on the adapter sleeve fastening forces in the eyepiece section encompassed by this is facilitated if the base body has a thinner wall thickness locally in the attachment section than in adjacent sections and thereby yielding slightly or einfedem locally and can be brought into contact with the eyepiece. As a result, a material saving of the adapter sleeve can be achieved without sacrificing positioning accuracy.
    The adapter sleeve may further comprise on the main body a radially inwardly projecting stop element, which forms a stop surface for axial abutment of the adapter sleeve on an end face of the OkuEarabschnitts, whereby in the optical axis direction a specific and each time identical position of N2011 / 29300 11/06 / 2012 16:45

    Adapter sleeve can be achieved. In addition, this stop element can be used for fixing the adapter sleeve in the axial direction, which can be used additionally or alternatively to a fixation by radial fastening forces.
    An advantageous embodiment of a fixing device consists in a clamping device with resilient and circumferentially distributed clamping elements on the base body, in particular in the form of a collet, and with a Kiem melemente radially displacing clamping member, in particular in the form of a union nut. Compared with an attachment with one or more radially arranged clamping screws more evenly distributed fixing forces can be effected on the eyepiece.
    Alternatively, the fixing device may comprise a stop element projecting radially inwards on the main body with a stop face for axial abutment of the main body on the eyepiece section and an axial clamping element, in particular an axial clamping sleeve, whereby radial forces on an eyepiece housing and consequent deformations can be reduced.
    The Axialspannelement can advantageously be formed by a screwed into the eyepiece eyecup assembly and thereby an already existing part of the eyepiece assembly can be used for an additional function.
    The advantageous effects described above can be utilized in particular in a fastening adapter according to claim 16.
    The object of the invention is also achieved by an adapter system having the features of claim 18. By using adapter sleeves with variable interior design and variable outer mount brackets, the use or replacement of the adapter sleeve provides a cost-effective solution; an existing optical accessory bracket is available in different sizes and sizes. * N2011 / 29300 11/06/2012 16:45

    By fixing the adapter sleeve in the axial direction with the eyecup arrangement radial forces can be reduced to the eyepiece and is a structurally very simple and inexpensive design of a fixing device for the adapter sleeve before.
    In this case, when the outer diameter of the Axialdruckfläche the eyecup assembly corresponds approximately to the outer diameter of the Okulargehäuses, an optimal distribution of the axial fastening forces is possible without hindering the axial attachment of an accessory.

    As shown in Hg. 1, the holder 5 is not attached directly to the eyepiece 2, but includes the mounting adapter 4 also attached to the eyepiece 2 AdapterhOlse 6 and the attachment of the holder 5 to the Adapterhdise 6, which can remain permanently on Okularabschnrtt 2 and allows both a normal observation through the observation telescope 3 through as well as a simple assembly and disassembly of the holder 5 with the recording or measuring device 1 allows.
    The eyepiece section 2 has a substantially cylindrical shape and may correspond to the actual eyepiece of the observation telescope 3 or a cylindrical housing part at the observer-side end of the observation telescope 3.
    The adapter sleeve 6 can not only be used for fastening a holder 5, but also used in general for attachment of any accessory 7 on the eyepiece section 2 grazing.
    The adapter sleeve 6 serves to be able to bring an accessory 7 in a defined position relative to the optical axis 8 of the observation telescope 3 and this positioning can be done even with multiple disassembly operations or assembly operations of an accessory 7 always with the necessary repeatability. In order to achieve this, it is necessary that both the adapter sleeve 6 on the eyepiece section 2 and the accessory 7 on the adapter sleeve 6 can each be mounted in a defined position. In addition to the axial positioning, this particularly concerns measures for centering the adapter sleeve 6 on the eyepiece section 2 and an accessory 7 on the adapter housing 6, whereby, for example, an optical axis of a recording or measuring device 1 can be positioned exactly in the optical axis 8 of the observation tube 3.
    The adapter sleeve 6 consists essentially of a hollow cylinder-like base body 9, which comprises the eyepiece section 2 on an outer periphery. For non-positive and / or positive position securing of the adapter sleeve 6 on the eyepiece section 2, this further comprises a fixing device 10, with which the required N2D11 / 29300

    The centering of the adapter sleeve 6 on the eyepiece section 2 takes place on its inner surface 11, which has at least one Innenzentrierfläche 12 which contacts the eyepiece section 2. Preferably, the inner center surface 12 cooperates with an outer periphery 13 of the eyepiece section 2, but it is also possible that the Centering on an end face or even an inner surface of the eyepiece 2 takes place
    The attachment of an accessory 7 on the adapter sleeve 6 takes place on an outer surface 14 of the adapter sleeve 6, which aulweist for the purpose of centering the accessory 7 a Außenzentrierfläche 15 a, which serves the accessory 7 in a defined position relative to the adapter sleeve 6 and thus also be able to bring 3 based on the observation telescope. ----------
    The outer centering surface 15 comprises a first outer centering section 16 at the observer-side end with a constant smaller outer diameter 17 and in the observation direction 18 following a second outer centering section 19 with a constant larger outer diameter 20. Thus, the accessory 7 is centered on the adapter sleeve 6 not only on a cylindrical portion, but at least at two different cylindrical sections, whereby a more accurate centric positioning can be done. The inner surface of the accessory 7, e.g. the holder 5, preferably also has two sections with different diameters.
    Furthermore, the outer surface 14 has a fastening portion 21, on which fastening forces between the accessory 7 and the adapter sleeve 6 are transmitted. In the accessory 7 fastening means 22 are provided, which can be deactivated and activated, whereby the accessory 7 can be detachably connected to the adapter sleeve 6. As a fastening means 22, for example, clamping screws, clamping elements, collets, clamping rings, clamping sleeves, etc. are used. 11/06/2012 16:48

    As shown in FIG. 1, the outer centering sections 16, 19 and the fastening section 21, viewed on the outer surface 14 of the adapter sleeve 6 in the viewing direction 18, are arranged at least behind the fixing device 10. This causes, as will be explained with reference to further figures in sequence, an additional improved positioning accuracy for attached to the adapter sleeve 6 on the observation tube 3 accessories 7th
    The fixing device 10 of the adapter sleeve 6 is preferably, as shown in Fig. 1, arranged in the observer-side end portion 23 or at least in the observer third of the total length of the adapter sleeve 6, thereby behind in the direction of observation 18 still sufficient space for the Außenzentrierabschnitte 16,19bzw. the attachment portion 21 is present.
    Fig. 2 shows a longitudinal section through an attached to a dashed line eyepiece 2 adapter sleeve 6, to which a likewise indicated by dashed lines accessory 7, for example in the form of a holder 5 is attached. In this embodiment, the fixing device 10 is arranged unmitteibar at the observer-side end of the base body 9 and are effected with this between the Adap terhülse 6 and eyepiece 2 effective fastening forces In the observation direction 18 below, the inner surface 11 forms the Innenzentrierfiä-che 12, for centering the Adapter sleeve 6 on the outer circumference 13 of Oku larabschnitts 2 is used
    The attachment portion 21 of the adapter sleeve 6 is here disposed between the outer-centering sections 16,19, whereby the accessory 7 is supported on both sides of the mounting portion 21 and an eccentric displacement relative to the optical axis 8 due to the clamping forces can be avoided.
    At this point, it should be noted that the fixing device 10 itself can cause centering of the adapter sleeve 6 on the eyepiece section 2 and that an inner centering surface 12 can transmit forces between the adapter housing 6 and the eyebrow section 2. In order to distinguish between an inner centering surface 12 and a fixing device 10, it is stated that the fixing device N2011 / 29300 11/06/2012 16:49

    Between an inner centering surface 12 of the Adapterhüise 6 and an outer periphery 13 of the Okularabschnitts 2 is generally a minimal game, so that the adapter sleeve 6 can be placed without problems on the eyepiece 2. By contrast, in the area of the fixing device 10, a clearance between the adapter housing 6 and the eyepiece section 2 can largely be ruled out. A fixing device 10 further effects the retention of the Adapterhüise 6 in the axial direction of observation 18, while a Innenzentrierfläche 12 provides no significant contribution to the position assurance in the axial direction.
    In the embodiment according to FIG. 2, the outer centering section 19 and the fastening section 21 are viewed in the direction of observation 18, entirely behind the fixing device 10.

As a result, the portion of the adapter sleeve 6 lying to the left of the fixing device 10 is slightly raised relative to the optical axis 6 of the eyepiece section 2. According to the invention, the accessory 7 is seen in the direction of observation 18, either fixed to the fixing portion 21 of the adapter sleeve 6 or at least centered on an outer centering surface 15 of the AdapterhQIse 6, whereby a second pivot point 26 for the tilting of the accessory 5 relative to the AdapterhQIse 6 may be formed can. Due to the acting load moment 24, the accessory 7 can additionally be slightly tilted further clockwise with respect to the adapter sleeve 6, as a result of which the portion of the accessory 7 located in FIG. 3 on the right of the second pivot point 26 decreases slightly downwards with the distance from the pivot point 26. By these two opposing displacements, which cancel each other at least partially, the positional deviation of a recording or measuring devices 1 on the holder 5 or the accessory 7 of the optical axis Θ can be kept lower overall than in the embodiment shown in FIG Adapter HQIse 6 according to the prior art.
