Description

The invention relates to a long-range optical device, in particular a pair of binoculars, comprising a housing body and at least one fastening device for fastening a third object, in particular a belt, to the housing body. Corresponding long-range optical devices are known in principle from the prior art and comprise a housing body that typically receives one or more optical elements, such as optical lenses, and a fastening device for fastening a third object, in particular a belt, to the housing body. Although the fastening devices of known long-range optical devices comprise a reliable, if necessary detachable, fastening of a third object, such as a belt or carrying strap, to the housing body, they are hitherto configured in a complicated manner with respect to construction and handling. This can result in a user having difficulty in transferring a fastening element belonging to a corresponding fastening device from a fastening position, in which a third object is fastened to the housing body, into a non-fastening position, in which the third object is not fastened to the housing body, for example because the actuations of the fastening element necessary for this and to be performed on the user side-which generally require pivoting of the fastening element about a pivot axis-are effective and/or intuitive only to a limited extent with regard to the forces that are generated thereby and act on the fastening element. The object of the invention is that of specifying a long-range optical device that is improved in comparison. The object is achieved by a long-range optical device according to independent claim 1. The claims dependent thereon relate to possible embodiments of the long-range optical device. A first aspect of the invention relates to a long-range optical device. The long-range optical device generally constitutes an optical device which is configured for observing objects located at a distance with respect to a location of a user-these are to be understood as both animate and inanimate objects. When used as intended, the long-range optical device is intended to be held by a user to at least one eye by at least one hand, such that a user can look through at least one optical channel of the long-range optical device that accommodates one or more optical elements. A corresponding optical channel typically extends between an eyepiece and an objective; the one or more optical elements, such as optical lenses, prisms, etc., are therefore typically arranged between an eyepiece and an objective. Of course, the eyepiece and the objective can also each be formed by or comprise at least one optical element, in particular in the form of a lens. The long-range optical device can, typically on account of the optical properties of the one or more optical elements accommodated in the optical channel, allow for an, optionally variable, manyfold optical enlargement. This is not necessarily the case, however-the long-range optical device can therefore optionally also allow only for a single enlargement. However, if the long-range optical device allows for an, optionally variable, manyfold optical enlargement, it can be configured as binoculars or a telescope. In particular, embodiments as what is known as a monocular or binoculars, for example in a roof edge or Porro configuration, are also possible. In an embodiment as binoculars, the long-range optical device comprises two housing bodies; each housing body comprises an eyepiece and an objective, as well as one or more optical elements arranged between the eyepiece and the objective. Each housing body thus forms an optical channel; the central axes of the optical channels of respective housing bodies typically can be or are arranged in parallel with one another. Similar applies for embodiments as a monocular, in which the long-range optical device comprises just one (single) housing body and one single optical channel. In addition to the mentioned configuration as binoculars or a telescope, the long-range optical device can be configured e.g. as an infrared vision device, night vision device, etc. Thus, in a basic configuration, in all cases the long-range optical device comprises at least one housing body. The at least one housing body can be configured in one piece or in multiple parts; at least one optical element is accommodated in the at least one housing body; the at least one housing body thus forms an optical channel of the long-range optical device. The long-range optical device further comprises at least one fastening device for fastening a third object to the at least one housing body. The third object can be a belt or a carrying strap. A corresponding belt or carrying strap can make it possible to carry the long-range optical device around the neck in a manner known per se. As emerges in the following, the at least one fastening device can be configured, depending on the configuration of the third object, to fasten the third object to the at least one
