Description

[Technical Field]

[0001] The present invention relates to a long-range optical device, in particular a binocular, comprising a housing body and at least one fastening device for attaching a third element, in particular a belt, to the housing body. [Background technology]

[0002] Corresponding long-range optical devices are known in principle from the prior art and typically comprise a housing body that accommodates one or more optical elements, such as optical lenses, and a fixing device for attaching a third element, in particular a belt, to the housing body.

[0003] Known fastening devices for long-range optical devices attach a third element, such as a belt or carrying strap, to the housing body in a reliable and, if necessary, detachable manner, but have so far been constructed in a complicated manner in terms of structure and handling.

[0004] For example, the actuation of the fixing element required for movement, which must be performed by the user, generally requires the fixing element to be rotated around a pivot axis, but the resulting force acting on the fixing element is only effective and / or intuitive within a limited range, making it difficult for the user to move the fixing element belonging to the corresponding fixing device from a fixed position in which the third element is attached to the housing body to an unlocked position in which the third element is not attached to the housing body. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION It is an object of the present invention to identify a relatively improved long range optical system. [Means for solving the problem]

[0006] This object is achieved by a long-range optical device according to independent claim 1. The dependent claims relate to possible embodiments of the long-range optical device.

[0007] A first aspect of the present invention relates to a long-range optical device. A long-range optical device generally comprises an optical device configured to observe an object (understood to be both animate and inanimate) located distal to a user's position. In intended use, the long-range optical device is held by at least one hand of the user at the position of at least one eye, allowing the user to view the object through at least one optical channel of the long-range optical device, which contains one or more optical elements. The corresponding optical channel typically extends between an eyepiece and an objective lens, and one or more optical elements, such as optical lenses, prisms, etc., are therefore typically disposed between the eyepiece and the objective lens. Of course, each of the eyepiece and the objective lens may be formed with or comprise at least one optical element, in particular in the form of a lens.

[0008] Long-range optical devices typically allow for optionally variable optical magnification due to the optical properties of one or more optical elements contained in the optical channel, but this is not required and long-range optical devices may optionally only have a single magnification.

[0009] However, the long-range optical device can also be configured as binoculars or telescopes, provided that it allows for an optionally variable optical magnification. In particular, embodiments known as monoculars or binoculars, such as roof-edge or polo-style, are also possible. In the binocular embodiment, the long-range optical device comprises two housing bodies, each housing body comprising an eyepiece, an objective lens, and one or more optical elements arranged between the eyepiece and the objective lens. Thus, each housing body forms an optical channel, the central axes of which can or are typically arranged parallel to one another. The same applies to a monocular embodiment, in which the long-range optical device comprises only one (single) housing body and one single optical channel.

[0010] In addition to binocular or telescopic configurations, long range optical devices may be configured as, for example, infrared vision devices, night vision devices, and the like.

[0011] In a basic configuration, therefore, the long-range optical device in all cases comprises at least one housing body, which may be constructed in one or more parts, and in which at least one optical element is accommodated, and which therefore forms the optical channel of the long-range optical device.

[0012] The long-range optical device further comprises at least one fastening device for attaching a third element to the at least one housing body. The third element can be a belt or a carrying strap. A corresponding belt or carrying strap allows the long-range optical device to be worn around the neck in a known manner. As will be apparent below, depending on the configuration of the third element, the at least one fastening device can be configured to attach the third element to the at least one housing body directly or indirectly, i.e., via at least one intermediate part, such as a mounting piece.

[0013] The at least one fixing device comprises at least one fixing element movable with one degree of displacement between a fixed position in which a portion of the third element received in the receiving device is attached to the at least one housing body and an unlocked position in which a portion of the third element received in the receiving device is not attached to the at least one housing body. Thus, the at least one fixing device moves the at least one fixing element from the fixed position to the unlocked position to enable (non-damageable or non-destructive) attachment of the third element to the at least one housing body. When the at least one long-range optical device comprises multiple housing bodies, each housing body may comprise at least one fixing element movable with one degree of displacement between a fixed position in which a portion of the third element received in the receiving device is attached to the at least one housing body and an unlocked position in which a portion of the third element received in the receiving device is not attached to the at least one housing body.

[0014] Each receiving device may be defined by one or more walls of the receiving unit. The one or more walls may form a receiving shaft that houses a portion of the third element or a corresponding attachment piece that is connectable or connectable to a portion of the third element. The receiving shaft has a depth extending in the receiving shaft axial direction. In cross-section, the receiving shaft may have a shape that corresponds to the cross-sectional shape of each portion of the third element or attachment piece.

[0015] Each receiving unit is formed integrally with at least one housing body or as an independent module from the at least one housing body, the independent module being attachable or mountable in a stable manner to the at least one housing body by one or more form-fitting and / or force-fitting and / or integral fastening means, which may be, for example, clamps, latches, screws or adhesive means.

[0016] Importantly, the at least one locking element is mounted so as to be movable with one degree of freedom of displacement. Therefore, the at least one locking element must be movable with one degree of freedom of displacement in order to be moved between the locked position and the unlocked position. The corresponding movement of the at least one locking element therefore occurs within or along a movement axis formed by at least two points, where the first point typically corresponds to the locked position of the at least one locking element and the second point typically corresponds to the unlocked position of the at least one locking element. Since the at least two points particularly form a straight line, the movement axis is typically a linear axis. The movement axis is typically arranged or oriented at an angle, particularly a right angle, to the axis of the receiving shaft. Therefore, the movement direction for moving the at least one locking element to the locked position and / or the unlocked position may be at an angle, particularly a right angle, to the movement direction for inserting a third element, particularly at least one coupling effective part, which is coupleable or coupled to the third element and will be described in more detail below, into the receiving device.

[0017] The fact that the at least one locking element is moved into the locked and / or unlocked position by a simple translational movement in or along the axis of movement, taking into account the forces that arise thereby and act on the locking element, provides a solution that makes the actuation of the at least one locking element to be carried out on the part of the user for moving the at least one locking element into the locked and / or unlocked position very effective and / or intuitive, in particular in contrast to known swivel mountings.

[0018] Thus, an overall improved long range optical system is provided.

[0019] The at least one fixing device may be arranged or formed on or in the at least one housing body. This allows for a reliable structural arrangement of the at least one fixing device on a typically highly stable component of the long-range optical device, in particular on the at least one body. Thus, forces, particularly tensile forces, that may act on the at least one fixing device when the long-range optical device is in use can be absorbed by the highly stable component of the long-range optical device.

[0020] In particular, the at least one fastening device can be fastened, in particular removably, on or in the at least one housing body as an independent module. This is particularly advantageous in terms of production, since the at least one fastening device can be manufactured as an independent module. Furthermore, at least one fastening device configured as an independent module can be (more) easily replaced, for example in case of damage. The removably fastening of the at least one fastening device to the at least one housing body can be achieved, for example, by one or more form-fitting and / or force-fitting and / or integral fastening means, which can be or comprise, for example, clamps, latches or screw means.

[0021] The at least one fastening element, in the fastening position, comprises at least one effective connecting portion, in particular at least one effective connecting portion of a mounting piece that can be or is to be connected to a third element, so as to form a form-fitting fastening of the third element to the at least one housing body. Thus, in the fastening position, the interaction of the at least one effective portion of the at least one fastening element with the at least one effective connecting portion connected to the third element allows for a form-fitting connection to be established, which typically allows for a very stable fastening of the third element to the at least one housing body, especially with respect to absorbable forces, i.e., tensile forces. As will be apparent from the following, the at least one effective connecting portion can be connected to the third element directly or indirectly, i.e., via at least one component or a group of components.

[0022] At least one effective part of at least one locking element may be configured as a form-fitting part, and at least one coupling effective part that is coupleable or coupled to a third element may be configured as a corresponding coupling form-fitting part. The corresponding form-fitting and coupling form-fitting parts may be structurally implemented, for example, by mirrored latch elements and / or snap elements. Accordingly, the corresponding form-fitting and coupling form-fitting parts may optionally be realized, for example, by undercuts, protrusions, and corresponding receiving areas. Optionally, the guided movement of the locking element into the locked position and / or the unlocked position may also be realized or at least assisted by the corresponding form-fitting and coupling form-fitting parts.

[0023] In a specific embodiment, in the locking position, at least one connecting portion may be formed by a recess, in particular extending transversely to the longitudinal extension of the at least one connecting portion. In particular, two leg-like or leg-shaped connecting portions may be provided, defining an intermediate space forming a corresponding recess. The two leg-like or leg-shaped connecting portions are configured such that, in the area of ​​their mutually facing surfaces, each has at least one protrusion oriented toward the respective connecting portion, so that each leg-like or leg-shaped connecting portion has a respective L-like or L-shaped basic shape, with the short ends of the Ls facing each other. The corresponding at least one effective portion therefore has a T-like or T-shaped basic shape, with the short ends of the Ls engaging behind or around the short ends of the Ts in the locking position. Thus, generally, at least one effective portion is configured with one or more undercuts, behind which at least one connecting portion can engage in the locking position.

[0024] It should be noted that the at least one connection effective feature can be connected to the third element directly or indirectly, i.e., via at least one component or a group of components. For example, an indirect connection embodiment can be realized in which the at least one connection effective feature is arranged on or formed on a mounting piece arranged on or formed together with the third element. The corresponding mounting piece can be formed from a different material or material structure than the third element, which may in particular be a belt, as described above. Therefore, the corresponding mounting piece can be formed from a material or material structure that is sufficiently strong to withstand possible forces, in particular tensile forces. Therefore, in particular, the corresponding mounting piece can be formed from or include a plastic material, in particular a hard plastic material, or a metal. Therefore, the corresponding mounting piece can be, for example, an injection-molded part, a milled part, a bent part, a stamped part, a 3D-printed part, etc.

[0025] The at least one effective part is configured in particular with a sloped or sloped insertion part on which a force can be exerted to move or to move the at least one locking element to the unlocked position when the coupling effective part is inserted into the receiving device, whereby the force required to move the at least one locking element to the unlocked and / or locked position can be more easily and better "felt", so that the movement of the at least one locking element to the unlocked and / or locked position can be realized and the user can potentially feel this movement tactilely.

[0026] The corresponding insert can be configured, for example, as a sloped or inclined surface, in particular in relation to the base of the fastening element. The corresponding insert, i.e. in particular the corresponding inclined surface, can be arranged or formed on an upper side of the at least one fastening element facing away from the insertion opening into the receiving device.

[0027] The long-distance optical device may include a restoring device associated with the at least one fixing device, the restoring device configured to apply a restoring force that moves the at least one fixing element to the fixed position. The restoring force is applied to the at least one fixing element by the restoring device to move the fixing element to the fixed position, typically acting in the direction of the movement axis. The force vector of the restoring force typically acts in the opposite direction to the movement vector of the at least one fixing element, moving the fixing element to the unlocked position. Because the at least one fixing element is always moved into or toward the fixed position by the restoring device, the restoring device can prevent undesired loss of a third element fixed to the at least one housing body by the at least one fixing device. Therefore, because the at least one fixing element is always moved into or toward the fixed position by the restoring device, the restoring device eliminates the need for a user to actively move the at least one fixing element to the fixed position or to fix it in the fixed position. Therefore, the home position of the at least one fixing element can be the fixed position.

[0028] The restoring device may comprise at least one restoring element configured as or comprising a return spring, i.e. in particular a compression spring, which may be configured to exert a restoring force that moves the at least one locking element to the locked position. The return spring, as well as any other locking elements, may be arranged or oriented with its spring axis at the axis of movement, so that the force vector of the restoring force opposes the movement vector of the at least one locking element, moving it to the unlocked position.

[0029] The long-range optical device comprises an adapter device at least partially defining a receiving space, the adapter device being removably fixable or attached to at least one housing body. Since different sizes of adapter devices can provide different sizes of receiving spaces for different sizes of coupling effective portions, the corresponding adapter device allows the at least one fixing device to be adjusted to or attached to different sizes of coupling effective portions.

[0030] The long-range optical device comprises an actuation device, the actuation device comprising an actuation element coupled, i.e. in particular movably coupled, to the fixation element, such that a user can actuate the actuation element to move the at least one fixation element to at least an unlocked position. Corresponding user actuation of the actuation element also serves to temporarily hold the fixation element in the unlocked position. Appropriate application of a force to move the fixation element to the unlocked position is realized by the corresponding actuation device, and handling of the at least one fixation device can be improved.

[0031] The actuating element may be arranged in such a way that, in the fixed position, it has an exposed actuating part that terminates (substantially) flush with the exposed outer surface of the at least one housing body, and thus the actuating element is arranged or configured in such a way that it is highly integrated with the at least one housing body, and in particular the outer shape of the at least one housing body is not (or is only slightly) changed by the actuating element.

[0032] A second aspect of the present invention relates to a fixing device for a long-range optical device according to the first aspect of the present invention, comprising a fixing element movable with one degree of displacement between a fixed position in which a part of the third element received in the receiving device is attached to at least one housing body of the long-range optical device, and an unlocked position in which the part of the third element received in the receiving device is not attached to at least one housing body of the long-range optical device.

[0033] A third aspect of the invention relates to a long range optical assembly comprising a long range optical device according to the first aspect and a third element attachable or attached to at least one housing body of the long range optical device by a fixing device.

[0034] All statements made regarding the long range optical device according to the first aspect of the invention apply equally to the fixing device according to the second aspect of the invention and to the long range optical assembly according to the third aspect of the invention.

[0035] The present invention will be described again below based on embodiments with reference to the drawings. [Brief explanation of the drawings]

[Figure 9] Schematic diagram illustrating an active portion and a coupling active portion according to one embodiment. [Figure 10] FIG. 1 is an enlarged view of an adapter device for a long-range optical device according to one embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0037] FIG. 1 is a schematic perspective view showing a long-range optical device 1 according to one embodiment.

[0038] Long-range optical device 1 generally constitutes an optical device configured to observe an object (understood as both animate and inanimate objects) located distal to a user's position. In intended use, long-range optical device 1 is intended to be held by a user in at least one hand at the position of at least one eye, allowing the user to view the object through an optical channel of long-range optical device 1 that houses one or more optical elements. A corresponding optical channel typically extends between each eyepiece 3 and each objective lens 2, and one or more optical elements, such as optical lenses, prisms, etc., are therefore typically disposed between each eyepiece 3 and each objective lens 2. Of course, each eyepiece 3 and each objective lens 2 may be formed in or comprise at least one optical element, in particular in the form of a lens.

[0039] Long-range optical device 1 may typically allow for optionally variable optical magnification, depending on the optical properties of one or more optical elements received in each optical channel, however, this is not required and therefore long-range optical device 1 may optionally only have a single magnification.

[0040] 1, the long-distance optical device 1 is configured, for example, as a pair of binoculars, optionally capable of variable optical magnification. The binoculars comprise two housing bodies 4, each comprising an eyepiece 3, an objective lens 2, and one or more optical elements arranged between the eyepiece 3 and the objective lens 2. Each housing body 4 thus forms an optical channel, and the central axes of the optical channels of each housing body 4 can be or are typically arranged parallel to one another.

[0041] Thus, in its basic configuration, the long-range optical device 1 in all cases comprises at least one housing body 4. The housing body 4 can be constructed in one piece or in multiple pieces, and as mentioned above, at least one optical element is accommodated in the at least one housing body 4, and each housing body 4 forms an optical channel of the long-range optical device 1.

[0042] As can be seen in Figure 1, each body 4 of the long-range optical device 1 is formed with a fixing device 5 for attaching a third element (not shown). The third element can be a belt or a carrying strap that allows the long-range optical device 1 to be carried around the neck in a manner known per se. As will become apparent below, depending on the configuration of the third element, each fixing device 5 can be configured to attach the third element to the respective housing body 4 directly or indirectly, i.e. via at least one intermediate part, for example a mounting piece 6.

[0043] The following description of the fixed device 5 applies equally to each fixed device 5 of the long-range optical device 1.

[0044] The fixing device 5 includes a fixing element 8, which is movable with one degree of displacement between a fixed position, as shown in FIG. 2 , for example, in which a portion of the third element received in the receiving device 7, specifically the mounting piece 6, is attached to the housing body 4, and an unlocked position, as shown in FIG. 3 , 4 , or 9 , for example, in which a portion of the third element received in the receiving device 7 is not attached to at least one housing body 4. Thus, by moving the fixing element 8 from the fixed position to the unlocked position, the fixing device 5 enables (non-damage or non-destructive) attachment of the third element to the housing body 4. When the long-distance optical device 1 includes multiple housing bodies 4, each housing body 1 may include a fixing element 8 movable with one degree of displacement between a fixed position, in which a portion of the third element received in the receiving device 7 is attached to the housing body 4, and an unlocked position, in which a portion of the third element received in the receiving device 7 is not attached to the housing body 4.

[0045] 2, 4, 5, 6 and 10, it can be seen that each receiving device 7 may be defined by one or more walls 7.1-7.4 of a receiving unit (not shown). One or more walls 7.1-7.4 may define a receiving shaft that accommodates a portion of a third element or a corresponding attachment piece 6 that can be coupled to or is coupled to the third element. The receiving shaft has a depth extending in the direction of the receiving shaft axis A1 (see in particular FIG. 6) and, as illustrated in the figures, may have a shape that corresponds in cross-section to the cross-sectional shape of each portion of the third element or attachment piece 6.

[0046] Each receiving unit is formed integrally with the housing body 4 or, as illustrated in the figures, as an independent module, which is attachable or attached to the housing body 4 in a stable manner by one or more form-fitting and / or force-fitting and / or integral fastening means 9. Corresponding fastening means 9 can be, for example, clamps, latches, screws or adhesive means. In the embodiment of Figure 1, screw means are shown purely by way of example.

[0047] It is important that the locking element 8 is equipped to be movable with one degree of freedom of displacement. Therefore, the locking element 8 needs to be movable with one degree of freedom of displacement to move between the locked position and the unlocked position. The corresponding movement of the locking element 8 therefore occurs in or along a movement axis A2 formed by at least two points, where a first point typically corresponds to the locked position of the locking element 8 and a second point typically corresponds to the unlocked position of the locking element 8. The at least two points particularly form a straight line, and therefore the movement axis A2 is typically a linear axis. In an embodiment, the movement axis A2 is typically arranged or oriented at an angle, i.e., particularly perpendicular, to the receiving shaft axis A1. Therefore, the movement direction for moving the locking element 8 to the locked position and / or the unlocked position can be angled, particularly perpendicular, to the movement direction for inserting a third element, particularly a coupling effective part (described in more detail below) that is coupleable or coupled to the mounting piece 6, into the receiving device 7.

[0048] The fact that the locking element 8 is moved into the locked and / or unlocked position by a simple translatory movement in or along the movement axis A2 provides a solution that comprises an actuation of the locking element 8 carried out on the part of the user, which, taking into account the forces that result and act on the locking element 8, moves the locking element 8 into the locked and / or unlocked position in a very effective and intuitive manner, especially in contrast to known swivel mountings.

[0049] As can be seen in the figure, the fixing device 5 can be arranged or formed on or within each housing body 4. This allows for a highly reliable structural arrangement of the fixing device 5 on typically very stable components of the long-range optical device 1, in particular on each housing body 4. Forces, particularly tensile forces, that may act on each fixing device 5 when the long-range optical device 1 is in use can thus be absorbed by the very stable components of the long-range optical device 1.

[0050] As can be seen in particular from the figures, the fixing device 5 can be fixed, in particular removably, on or in the housing body 4 as an independent module. This is advantageous, in particular in terms of production, since the fixing device 5 can be manufactured as an independent module. Furthermore, a fixing device 5 configured as an independent module can be (more) easily replaced, for example in case of damage. The removably fixing of the fixing device 5 to the housing body 4 can be achieved, for example, by one or more positive-fit and / or force-fit and / or integral fixing means, which can, for example, use or comprise clamps, latches or screws. In the embodiment of Figure 1, screw means are shown purely by way of example.

[0051] 7 to 9, which are axial views about the movement axis A2, the fixing element 8, in the fixed position shown in Fig. 7, comprises at least one effective part 8.1 which is configured to interact with a coupling effective part 6.1 of the attachment piece 6 which is coupleable or coupled to the third element, so as to form a form-fitting fixation of the third element to the housing body 4. In the fixed position, the interaction of the at least one effective part 8.1 with the at least one coupling effective part 6.1 makes it possible to create a form-fitting connection which typically allows a very stable fixation of the third element to the housing body 4 with respect to absorbable forces, i.e. in particular tensile forces (see arrow P1 in Fig. 9).

[0052] 7 to 9 that at least one effective part 8.1 can be configured as a form-fitting part and at least one connecting effective part 6.1 can be configured as a corresponding connecting form-fitting part. The corresponding form-fitting and connecting form-fitting parts can be realized structurally, for example, by mirror-inverted latching and / or snap elements. Accordingly, the corresponding form-fitting and connecting form-fitting parts can optionally be realized, for example, by undercuts, protrusions and corresponding receiving areas. Optionally, the guided movement of the fixing element 8 into the fixing position and / or into the unlocking position can also be realized or at least assisted by the corresponding form-fitting and connecting form-fitting parts.

[0053] In the illustrated embodiment, the at least one connecting portion is formed, in the locked position shown in FIG. 7, by a recess through which it passes, in particular transversely to the longitudinal extension of the at least one connecting portion. By way of example, two leg-like or leg-shaped connecting portions are provided, which define an intermediate space 10 forming a corresponding recess. The two leg-like or leg-shaped connecting portions are each configured with at least one projection 11 oriented toward the respective connecting effective portion in the area of ​​their surfaces facing each other, so that each leg-like or leg-shaped connecting portion has an L-shaped or L-shaped basic shape, with the short ends of the Ls facing each other. The corresponding at least one effective portion 8.1 therefore has a T-shaped or T-shaped basic shape, with the engagement of the ends of the Ls occurring behind or around the short end of the T in the locked position. 8 shows the locking element 8 in its unlocked position, where the locking element 8 is located behind the mounting piece 6 in the plane of the seat, and the form-fit connection shown in FIG. 7 is released, allowing the mounting piece to move in the direction of arrow P1 and finally separate from the housing body 4, as shown in FIG. 9.

[0054] It can be said that the at least one connection active part 6.1 can be connected to the third element directly or indirectly, i.e., via at least one component or a group of components. For example, as shown, the at least one connection active part 6.1 can be arranged on or formed on an attachment piece 6 arranged on or formed together with the third element, thereby realizing an indirect connection embodiment. The attachment piece 6 can be formed from a different material or material structure than the third element, which, as mentioned above, can be used, in particular for belts or carrying straps. Therefore, the attachment piece 6 can be formed from a material or material structure with a sufficient strength to withstand possible forces, especially tensile forces. Specifically, the attachment piece 6 can be formed from or include, for example, a plastic material, in particular a hard plastic material, or a metal.

[0055] It can be seen from Fig. 6 that the at least one effective part 8.1 is configured in particular with a sloped or sloped insertion part 8.2, so that a force can be exerted to move or to move the at least one locking element 8 into the unlocked position when the at least one coupling effective part 6.1 is inserted into the receiving device, whereby the movement of the locking element 8 into the unlocked position is realized and the user may be able to feel this movement tactilely, since the force required to move the locking element 8 into the unlocked position is easier and better "feelable".

[0056] In the embodiment of Fig. 6, the insert 8.2 is configured, by way of example, as a sloped or inclined inclined surface, in particular relative to the base 8.3 of the fastening element 8. In this embodiment, the insert 8.2, i.e. in particular the corresponding inclined surface, is arranged or formed on the upper side of the fastening element 8, facing away from the insertion opening for the receiving device.

[0057] 6 further shows that the long-distance optical device 1 includes a restoring device 12 associated with the fixing device 5, which can be configured to exert a restoring force that moves the fixing element 8 to the fixed position. The restoring force acting on the fixing element 8 by the restoring device 12 and moving the fixing element to the fixed position typically acts along the movement axis A2. Therefore, the force vector of the restoring force typically acts in the opposite direction to the movement vector of the fixing element 8, moving the fixing element 8 to the unlocked position. The restoring device 12 prevents undesired damage to the third element fixed to the housing body 4 by the fixing device 7, since the fixing element 8 is always moved to the fixed position by the restoring device 12. Therefore, the restoring device 12 eliminates the need for the user to actively move the fixing element 8 to the fixed position or to fix it there, since the fixing element 8 is always moved to the fixed position by the restoring device 12. Therefore, the home position of the fixing element 8 can be the fixed position.

[0058] In this embodiment, the restoring device 12 comprises a restoring element 12.1 configured as or comprising a return spring, i.e. in particular a compression spring, which is configured to generate a restoring force that moves the locking element 8 to the locking position. The return spring, as well as the other restoring elements, is arranged or oriented with its spring axis on the axis of movement A2, so that the force vector of the restoring force opposes the movement vector of the locking element 8, causing it to move to the unlocked position.

[0059] As can be seen from Figure 10, the long-range optical device 1 can be provided with an adapter device 13 which at least partially defines a receiving space and which can be or is removably fixed to the housing body 4. The corresponding adapter device 13 makes it possible to adjust the fixing device 5 for or provide the fixing device 5 on various sized coupling effective parts 6.1, since various sized adapter devices 13 can provide various sized receiving spaces for various sized coupling effective parts 6.1.

[0060] In all embodiments, the long-range optical device 1 comprises an actuation device 14 including an actuation element 14.1 which is coupled, in particular movably coupled, to the fixing element 8 such that a user can actuate the actuation element 14.1 to move the fixing element 8 at least to the unlocked position. A corresponding user actuation of the actuation element 14.1 can be seen in particular in Figures 3 and 4. Thus, a corresponding user actuation of the actuation element 14.1 also serves to temporarily hold the fixing element 8 in the unlocked position. A suitable introduction of a force to move the fixing element 8 to the unlocked position is realized by the corresponding actuation device 14, which allows for improved handling of the fixing device 5.

[0061] 2 and 5, the actuating element 14.1 can be arranged in such a way that in the fixed position it has an exposed actuating part which ends (substantially) flush with the exposed outer surface of the housing body 4. The actuating element 14.1 can thus be arranged or configured in such a way that it is highly integrated into the housing body 4, in particular the actuating element does not (or hardly) change the outer shape of the housing body 4.

[0062] The principles of moving the locking element 8 from the locked position shown in FIG. 2 to the unlocked position, as well as the principles of releasing the locking of the attachment piece 6 and releasing the third element connected to the attachment piece 6, will also be explained with reference to FIGS. 2 to 4.

[0063] From the state shown in Figure 2, actuation of the actuating element 14.1 in the direction of the movement axis A2 moves the locking element 8 against the force vector of the restoring element 12.1 and therefore against the force of the restoring element 12.1 to the unlocked position (see Figure 3). When the actuating element 14.1 is actuated, the attachment piece 6 can be removed again from the receiving device 7, as shown in Figure 6. After removing the attachment piece 6 from the receiving device 7, the locking element 8, and therefore the actuating element 14.1 coupled thereto, moves the locking element 8 in the direction of the movement axis A2, in the direction of the force vector of the restoring element 12.1, to the locked position (see Figure 5).
