DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(21) For example, FIG. 1 shows an optical sight 2, namely a reflex sight 2a with a closed design, on a partially depicted firearm 1. The optical sight 2 has two protective covers 3a, 3b linked to it for protecting the optical sight 2, which are shown in the folded-open position 4a in FIG. 1 and in the folded-closed position 4b in FIG. 2. For this purpose, the protective covers 3a, 3b each have a transparent end wall section 8a, 8b, which protects either a proximal opening 5 such as the ocular of reflex sight 2a or a distal opening 6 such as the objective of the reflex sight 2a. The proximal opening 5 and the distal opening 6 lay on an optical axis A of the optical sight 2. This reflex sight 2a has for example an ocular lens at the ocular and for example an objective lens at the objective. The reflex sight 2a constitutes, for example, a non-magnifying optical sight 2, imaging the target object in a ratio of 1:1 for the marksman.
(22) The transparent end wall sections 8a, 8b are also positioned along the optical axis A of the optical sight 2. Because the end wall sections 8a, 8b are transparent, even in the folded-closed and thus protected position 4b, it is possible to see through the optical sight 2.
(23) The protective covers 3a, 3b can also be embodied so they can be removed from the optical sight 2 individuallyas shown in FIG. 3. FIG. 3 shows the removed position 4a and FIG. 4 shows the position 4b in which they are clamped to the optical sight 2. These protective covers 3a, 3b also each have a transparent end wall section 8a, 8b.
(24) By contrast with the protective covers 3a, 3b that are shown in FIGS. 1 to 6 and are embodied as protective lids 11, 12, a third protective cover 3c that is shown in FIG. 7 and in FIG. 7a is embodied as a protective cap 13 that has two end wall sections 8a, 8b.
(25) According to the invention, the functionality of these protective covers 3a, 3b, 3c is enhanced such that its transparent end wall sections 8a, 8b enable provision of a permanently displayed optical reticle 9. Thus even in the event of a failure of an electrical/electronic reticle in the optical sight 2, based on the presence of the protective covers 3a, 3b, 3c, it is possible to aim using the reticle 9, 10 of the protective covers 3a, 3b, 3c. The firearm 1 is thus provided with a backup sight. In this connection, it advantageously does not matter how the protective covers 3a, 3b, 3c are connected to the optical sight 2, as has already been described above.
(26) As shown in FIGS. 1 to 7, the presence of the reticle 9 is enabled by the fact that the transparent end wall sections 8a, 8b each have a part 10a, 10b of the permanently displayed optical reticle 9. The first end wall section 8a has a first part 10a of this reticle 9 while the second end wall section 8b has a second part 10b of this reticle 9 that is different from the first part 10a. This can be seen, for example in FIGS. 1, 3, and 7, by virtue of the fact that the first part 10a is formed by two horizontal straight markings and the second part 10b is formed by one vertical straight marking.
(27) These two parts 10a, 10b jointly form the reticle 9as is shown by way of example for all of the embodiments illustrated in FIGS. 2, 3c, 4, 7, and 12. It can be seen that the permanently displayed parts 10a, 10b are embodied as lines and the optical reticle 9 is embodied as a pattern of these lines. According to certain embodiments, which may be applied to any of the embodiments described herein, the permanently displayed optical reticle 9 or the permanently displayed part 10a, 10b of the optical reticle 9 can be designed to be partially or completely illuminating.
(28) In general, the permanently displayed optical reticle 9 or the permanently displayed parts 10a, 10b of the optical reticle 9 may comprise at least a line, an aiming point, a dot, a square, a rectangle, a ring, a circle, one or more symbols, or even a combination thereof. Usually, an optical reticle 9 is embodied as a pattern of lines or markings.
(29) FIGS. 1 to 7 show that all of the protective covers 3a, 3b, 3c have a base body section 7a, 7b, 7c, which adjoins each transparent end wall section 8a, 8b. The protective covers 3a, 3b, 3c differ essentially based on the fasteners with which they are respectively attached to the optical sight 2.
(30) Thus the base body section 7a of the protective covers 3a, 3b embodied as protective lids 11 according to FIGS. 1, 2, and 5 each have a hinge element 21a for a respective swiveling hinge 21 on the optical sight 2. The other hinge element 21a of the relevant swiveling hinge 21 that cooperates with the first is provided on the optical sight 2. In addition, a snap mechanism is provided with the optical sight 2. For this purpose, the base body section 7a has a completely circumferential snap element 23 that secures the folded-closed position 4b of the protective covers 3a, 3b on the optical sight 2. Each snap element 23 is positioned on the elastic outer annular edge 24a, 24b of the base body section 7a. The base body section 7a also has a bezel 25a, 25b that encloses the respective transparent end wall section 8a, 8b and thus secures it on the base body section 7a.
(31) Instead of the hinge element 21a and the snap element 23, the protective covers 3a, 3b embodied as protective lids 12 according to FIGS. 3, 4, and 6 have a clamped connection to the optical sight 2. The clamped connection is produced by the elastic outer annular edge 24a, 24b of the base body section 7b, which due to its elasticity produces a non-positive connection to the optical sight. The annular edge 24a, 24b also has a sealing lip 22.
(32) As can also be seen in FIGS. 1 to 7, the outer elastic annular edge 24a, 24b adjoins the bezel 25a, 25b of the protective cover 3a, 3b. The annular edge 24a, 24b, the bezel 25a, 25b, and possibly the snap element 23 consist of an opaque, for example, non-translucent, material. The protective covers 3a, 3b are for example composed of one piece and consist of a plastic.
(33) For example, the base body sections 7a, 7b consist entirely of an elastic plastic, which for example facilitates manipulation of the protective cover 3a, 3b, 3c.
(34) The protective cover 3c for an optical sight 2 shown in FIG. 7 and FIG. 7a is embodied in the form of a rigid one-piece protective cap 13. For example, this embodiment is used with an open sight 2, namely an open reflex sight 2b, since this type of optical sight lacks a protective glass or lens at the proximal opening 5. This reflex sight 2b constitutes, for example, a non-magnifying optic sight 2, imaging the target object in a ratio of 1:1 for the marksman. This one-piece protective cap 13 has an opaque base body 7c and two transparent end wall sections 8a, 8b that are each movably fastened to it by means of a hinge. It is also conceivable, however, for there to be a one-piece protective cap 13 in that the end wall sections 8a, 8b are rigidly connected to the base body 7cfor example produced by means of a multi-component injection molding process.
(35) The first and second parts 10a, 10b of the reticle 9 consist of gaseous tritium light sources 14a, 14b, 15, which are fastened to the transparent end wall section 8a, 8b. These gaseous tritium light sources 14a, 14b, 15 are known as GTLS. In all of the exemplary embodiments, these radioluminescent gaseous tritium light sources 14a, 14b, 15 have an outer sleeve in the form of a hermetically sealed round glass tube made of borosilicate glass. The glass tube is coated on the inside with a luminophore such as zinc sulfide and filled with tritium.
(36) The transparent end wall section 8a, 8b consists of an inelastic plasticwhich for example facilitates the mounting of the gaseous tritium light sources 14a, 14b, 15. This is all the more true since the gaseous tritium light sources 14a, 14b, 15 are provided in recesses 16a, 16b, 17 in the transparent end wall section 8a, 8b, as shown in FIGS. 8 to 11. These recesses 16a, 16b, and 17 can be embodied in various ways.
(37) According to FIG. 8, drilled recesses 16a, 16b are provided extending in from the side surface of the transparent end wall section 8a of the protective cover 3a. This construction is also the case for the other recess 17 of the transparent end wall section 8b of the protective cover 3b. A gaseous tritium light source 14a, 14b, 15 is inserted into each of these drilled recesses 16a, 16b, 17 and glued in place with glue 18, as shown in FIG. 8a. The gaseous tritium light source 14a, 14b, 15 is thus encapsulated and protected from damage.
(38) According to FIG. 9, these milled recesses 16a, 16b are provided in the broad side of the transparent end wall section 8a of the protective cover 3a, which broad side is at the backi.e. facing the proximal opening 5 or the distal opening 6. This type of construction is also used for the other recess 17 of the transparent end wall section 8b of the protective cover 3b. A respective gaseous tritium light source 14a, 14b, 15 is inserted into each of these milled recesses 16a, 16b, 17 and glued in place with glue 18, as shown in FIG. 9a. The gaseous tritium light sources 14a, 14b, 15 are thus encapsulated and protected from damage.
(39) According to FIG. 10, these recesses 16a, 16b are provided in a sandwich construction for example composed of two material layers 19a, 19b of the transparent end wall section 8a of the protective cover 3a. This construction is also the case for the other recess 17 of the transparent end wall section 8b of the protective cover 3b. A gaseous tritium light source 14a, 14b, 15 is provided in each of the recesses 16a, 16b, 17 provided between these layers, as shown in FIG. 10a. The gaseous tritium light sources 14a, 14b, 15 are thus encapsulated and protected from damage.
(40) According to FIG. 11, these recesses 16a, 16bthe same as the ones in FIG. 10are also provided in a sandwich construction composed of two material layers 19a, 19b of the transparent end wall section 8a of the protective cover 3a. The second material layer 19b extends over the circumference of the transparent end wall section 8a, which is adjoined by the two central bridge pieces 20a, 20b that extend toward each other. The gaseous tritium light sources 14a, 14b are provided in these bridge pieces 20a, 20b, as shown in FIG. 11a. The gaseous tritium light sources 14a, 14b are thus encapsulated and protected from damage.
(41) According to FIG. 3c, in the first protective cover 3a, the first horizontal and second horizontal gaseous tritium light sources 14a, 14b also come to an end before the center Z of the transparent end wall section 8a spaced the same distance D apart from this center.
(42) Also, it can be seen in FIG. 3c, that the third vertical gaseous tritium light source 15 runs over the center Z of the reticle 9. The end of the third gaseous tritium light source 15 closes flat with the top of the first and second gaseous tritium light sources 14a, 14b. It is thus possible to facilitate the aiming.
(43) FIG. 12 shows, for example, an optical sight 2, namely a telescopic sight 2c, whose proximal opening 5 and distal opening 6 are each protected by the removable protective cover 3a, 3b. Thus, the protective cover 3a protects the ocular with the ocular lens 5a and the protective cover 3b protects the objective with the objective lens 6a of the telescopic sight 2c. The protective covers 3a, 3b are the same as described for FIG. 3 and their transparent end wall section 8a, 8b lay on the optical axis A of the optical sight 2. Also, the proximal opening 5 and the distal opening 6 lay on this optical axis A. The telescopic sight 2c constitutes, for example, a non-magnifying optic sight 2, imaging the target object in a ratio of 1:1 for the marksman. However, any other ratio is also conceivable.
