Riflescope with variable magnification

The invention relates to a telescopic sight with variable magnification, in which the magnification is changed via an adjusting ring.

Such riflescopes with variable magnification are already known from the prior art.

A riflescope is known from US Pat. No. 4,072,396, in which the adjusting ring is arranged on the objective lenses. This position of the collar is impractical for use. The same applies to the riflescope, which is known from US 3,423,146.

A riflescope is known from US Pat. No. 4,255,013, in which the adjusting ring projects beyond the rifle scope housing on the eyepiece side. Also in the scope, which is known from US 3,948,587, ^'projects of the adjusting ring in its entire circumference on the housing of the sighting telescope out.

In the case of the riflescopes, which are known from US Pat. Nos. 3,782,822 and 4,172,634, the adjusting ring is arranged on the eyepiece side, but here also protrudes from the housing of the rifle scope to the full extent.

The object of the invention is to obtain a higher stability of the housing together with a simplification of production, the adjustment being carried out at a position which is favorable in the position of use and allowing the design of an essentially smooth surface.

This object is achieved by the characterizing part of the first claim. If, according to the invention, the riflescope housing and the eyepiece socket are made together from one part, then not only a part for the riflescope can be produced less. This simplification of production also has the advantage that the connection between the two parts is solid and that this results in a higher stability of the system.

A groove is advantageously provided between the telescopic sight housing and the eyepiece socket, in which the adjusting ring is guided. This measure ensures reliable guidance of the adjusting ring in the direction of the optical axis.

In order to obtain simple assembly, the adjusting ring is advantageously arranged around the scope housing.

The assembly of the adjusting ring is much less complicated if the adjusting ring is made up of two half-shells, which are assembled to form a circular body when assembled. This also allows the removal of the use of only certain materials for the collar.

In particular, the use of light metal or a hard plastic for the half-shells of the collar is advantageous.

So that the magnification can be varied, a pin receptacle should be fitted in the adjusting ring and a pin should protrude into this pin receptacle, the pin being able to drive the inner movement elements.

To secure the collar against unintentional disassembly into its two components, an elastic auxiliary body should be arranged around the collar.

The elastic auxiliary body is advantageously made of rubber, which can additionally seal the opening in the rifle scope housing. In order to create a good connection between the adjusting ring and auxiliary body, recesses and / or raised parts should be arranged in the adjusting ring, which engage in corresponding raised parts and / or recesses of the elastic auxiliary body.

The invention is explained in more detail below by way of example with reference to the figures, further advantageous features and explanations and configuration options for the understanding of the invention serving to improve understanding being described.

FIG. 4 shows a side view of the telescope cover in the area of the magnification setting according to the invention;

Figure 5a shows a section through the outer rubber coating; and

Figure 5b shows a detail of a view of the outer rubber coating. FIG. 1 shows a section through the rifle scope (1) according to the invention with variable magnification in the area where the eyepiece socket meets the rifle scope housing. The scope housing is made from one part (2) together with the eyepiece socket.

Between the eyepiece socket and the rest of the rifle scope housing there is a groove (3) (see also FIG. 4), which represents a guide for the adjusting ring (4). An elastic auxiliary body (5) made of rubber is arranged around the adjusting ring (4) and is put around the adjusting ring (4) after it has been installed.

In the collar (4) there is a pin holder (4a) into which a pin (6) protrudes. This pin (6) transmits the radial movement of the adjusting ring (4) to an inner hollow cylinder (7), which causes the necessary lens movements. On the opposite side of the rifle scope housing (2) there is also a pin (8) which provides a counterforce to the actuating pin (6).

The adjusting ring (4) together with the auxiliary body (5) does not protrude beyond the upper edge of the groove (3).

The half-shells (4.1, 4.2) of the adjusting ring (4) are shown in FIGS. 2a and 2b as well as in FIGS. 3a and 3b.

The upper half-shell (4.1) is an annular body and has a semi-circular cross-section which is larger than 180 °. In the upper part of this half-shell (4.1) there is a bulge (4.1a), the inward opening (4a) of which serves as a pin receptacle. To the side of this bulge (4.1a), the half-shell (4.1) has a rectangular opening (4.1b, 4.1c).

At the ends of the upper half-shell (4.1) there are two T-shaped openings (4.1d, 4.le). The lower half-shell (4.2) is also an annular body and also has a semicircular cross-section which is larger than 180 °. It has two rectangular openings (4.2b, 4.2c) on the side of its lowest point (4.2a).

At the ends of the lower half-shell (4.2) there are two T-shaped extensions (4.2d, 4.2e) which fit exactly into the T-shaped openings (4.1d, 4.1e) of the upper half-shell (4.1).

If the two half shells (4.1, 4.2) made of plastic are put together, then the two T-shaped extensions (4.2d, 4.2e) engage in the two T-shaped openings (4.1d, 4.1e) and the two half shells (4.1, 4.2) form a closed circle without play.

If the adjusting ring (4) with its two half-shells (4.1, 4.2) is mounted in the groove (3) of the rifle scope housing (2), the elastic auxiliary body (5) shown in cross section in FIG. 5a is thus placed over the adjusting ring (4 ) placed that its recess (5a) and its raised parts (5b-5e) exactly on the bulge (4.1a) or in the rectangular openings (4.1b, 4.1c, 4.2b, 4.2c) of the adjusting ring ( 4) grab. To indicate the position of the adjusting ring (4) there are corresponding markings in the form of numbers and dots on the auxiliary body (5), as shown in FIG. 5b.
