Target tube adapter and target tube attachment with such a target tube adapter

Description

[0001] The invention relates to a telescopic sight attachment adapter for mounting attachment devices on a telescopic sight according to the preamble of claim 1. The invention further relates to a telescopic sight attachment with such a telescopic sight attachment adapter.

[0002] From WO 02 / 21065 A2, a generic telescopic sight adapter for mounting a night vision device or other attachment or add-on device to a telescopic sight is known. This telescopic sight adapter comprises a tubular housing with a cylindrical receiving area for mounting an attachment device and a slotted clamping area for securing the housing to a telescopic sight. The slotted clamping area features a longitudinally extending clamping slot and a clamping mechanism designed as a clamping lever, which allows the width of the clamping slot to be reduced. Such telescopic sight adapters can be mounted on conventional telescopic sights with cylindrical housings, but are not suitable for mounting on telescopic sights that have a protective cover at their front end to protect the optics.With such scope covers, the protective flaps are typically hinged on a radially projecting hinge and attached to a mounting ring that can be fastened to the front of the scope. The radially projecting hinge or other radially projecting parts of the scope cover prevent the use of conventional scope attachment adapters.

[0003] DE202021000644U1 also represents a relevant state of the art.

[0004] The object of the invention is to create a telescopic sight adapter and a telescopic sight attachment that have an extended range of applications.

[0005] This problem is solved by a telescopic sight adapter with the features of claim 1 and by a telescopic sight attachment with the features of claim 10. Advantageous embodiments and further developments of the invention are specified in the dependent claims.

[0006] The telescopic sight adapter according to the invention comprises a housing with a mounting area for attaching the accessory and a clamping area with a clamping slot and a clamping device for securing the telescopic sight adapter to the telescopic sight. The clamping area with the clamping slot features an additional, rearward-opening receiving groove and a bridge piece that can be placed on the receiving groove to prevent the receiving groove from widening when the clamping device is actuated. The telescopic sight adapter can be slid onto the receiving groove via a radially projecting hinge element or another radially projecting part of a telescopic sight cover, and thus can also be mounted on a telescopic sight equipped with a telescopic sight cover.The bridge piece ensures that the clamping area in the mounting groove does not deform and that clamping occurs within the clamping slot. This guarantees a stable and secure mounting of the scope adapter.

[0007] In a particularly practical design, the bridge piece can be formed by a cover flap of a telescopic sight cover. When folded back in the open position, the cover flap can simultaneously function as the bridge piece and, through a suitable connection with the clamping area of ​​the telescopic sight adapter, ensure that as little deformation as possible occurs in the clamping area around the mounting groove. Alternatively, the bridge piece can be designed as a separate component, for example, in the form of a mounting rail, a lid-shaped cover, or the like.

[0008] To prevent deformation of the receiving groove, the bridge component expediently features a groove on both sides of the receiving groove for the positive engagement of two connecting webs. The groove is preferably designed as a dovetail groove with angled inner surfaces to engage with the angled outer surfaces of the connecting webs. This creates a wedge effect for connecting the two connecting webs. Alternatively, the groove can also be designed as a T-slot for engaging corresponding connecting webs.

[0009] In an advantageous embodiment, the clamping slot can be formed by a longitudinal slot extending in the longitudinal direction of the clamping area and open to the rear, and a transverse slot extending circumferentially over part of the circumference of the clamping area at right angles to the longitudinal slot. The longitudinal slot and the transverse slot create a clamping section that is flexible in the radial direction.

[0010] The clamping device for the telescopic sight adapter can have two clamping pieces arranged on either side of the longitudinal slot, a clamping screw, and a clamping lever designed as an eccentric lever for exerting an axial force on the clamping screw. This allows the width of the longitudinal slot to be changed for clamping and releasing.

[0011] The invention also relates to a telescopic sight attachment with a telescopic sight cover and a telescopic sight attachment adapter described above for mounting the attachment on the telescopic sight.

[0012] The scope cover conveniently includes a hinged cover flap which, in a rearward-folded open position, engages with the scope attachment adapter to prevent the mounting groove from widening when the cocking device is operated.

[0013] Further features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawing. The drawing shows: Figure 1 a front part of a telescopic sight with a telescopic sight cover and a telescopic sight attachment adapter in a side view; Figure 2 a riflescope cover in one perspective; Figure 3 a rifle scope attachment adapter in one perspective; Figure 4 a sectional view along line AA of Figure 1 ; Figure 5 a telescopic sight adapter with a bridge piece designed as a mounting rail; Figure 6 a riflescope attachment adapter with an additional bridge piece and Figure 7 the in Figure 2 The telescopic sight cover shown has an insert.

[0014] In Figure 1 is the front part of a telescopic sight 1 with a in Figure 2 separately shown scope cover 2 and one in Figure 3The telescopic sight adapter 3, shown in a perspective view, is for mounting a night vision device, a thermal imaging camera or another attachment or add-on device to the telescopic sight 1.

[0015] As from Figure 2 As can be seen, the telescopic sight cover 2 has an annular retaining element 4 and a cover flap 5 pivotably mounted on the retaining element 4 to protect the telescopic sight optics. The articulated connection between the annular retaining element 4 and the cover flap 5 is formed by a hinge consisting of a web-shaped inner hinge element 6 projecting radially outwards from the annular retaining element 4, an outer hinge element 7 integrally formed on the cover flap 5, and a transverse pin 8. The cover flap 5 can be pivoted 270° via the hinge between a downward-folded closed position and a rearward-folded open position.

[0016] The cover flap 5 is pre-tensioned in a manner known per se by a spring (not shown) and has a locking mechanism, operable by means of an operating button 9, for holding the cover flap 5 in the closed position. By operating the operating button 9, the locking mechanism can be released, so that the cover flap 5 opens from the position due to the force of the spring. Figure 2 shown closing position in the Figure 1 The open position shown can be moved. On the outside of the cover flap 5, a groove 10, which will be explained in more detail below, is provided for positive engagement with the telescopic sight adapter 3. The groove 10, designed as a dovetail groove, has inclined inner side surfaces 11. The ring-shaped retaining part 4 of the telescopic sight cover 2, with the cover flap 5 attached to it, can be fastened to the front end of the telescopic sight 1 via a thread, a bayonet connection, or the like.

[0017] The in Figure 3The telescopic sight adapter 3, shown in a perspective view, comprises a housing with an annular front mounting area 12 for mounting the attachment and a rear, bushing-shaped clamping area 14 with a clamping slot 13 for clamping the telescopic sight adapter 3 onto the telescopic sight 1. The annular mounting area 12 may be provided with a thread, a bayonet fitting, or another suitable connection for mounting an attachment. In the embodiment shown, the clamping slot 13 is formed by a longitudinal slot 15 extending in the longitudinal direction of the clamping area 14 and opening to the rear, and a transverse slot 16 extending circumferentially around the clamping area 14 at approximately half its circumference and perpendicular to the longitudinal slot 15. The longitudinal slot 15 and the transverse slot 16 create a radially flexible clamping section 17, which can be pressed inwards to clamp the attachment.

[0018] On both sides of the longitudinal slot 15, at the clamping area 14 of the housing, there are two radially outwardly projecting first and second clamping pieces 18 and 19 with a threaded bore 20 and a through bore 21 for a Figure 1A visible clamping screw 22 is arranged. The clamping screw 22 is connected at its outer end, which projects from the second clamping piece 19, to a clamping lever 24 designed as an eccentric lever via a transverse pin 23. By folding in the clamping lever 24, the second clamping piece 19, arranged on the flexible clamping section 17, can be pulled against the first clamping piece 18 via the clamping screw 22, thus bending the clamping section 17 inwards to form the clamping bracket. By unfolding the clamping lever 24, the clamping can be released for the removal of the telescopic sight adapter 3. The two clamping pieces 18 and 19, the clamping screw 22, and the clamping lever 24 thus form a clamping device for securing the telescopic sight adapter 3 to the telescopic sight 1.

[0019] In Figure 3It is also evident that in the bushing-shaped rear clamping area 14 of the housing, in addition to the clamping gap 13, a rearwardly open receiving groove 25 is provided, offset circumferentially from the longitudinal gap 15, for receiving the radially outwardly projecting hinge part 6 on the retaining part 4 of the telescopic sight cover 2. The telescopic sight adapter 3 can be slid over the radially outwardly projecting hinge part 6 of the telescopic sight cover 2 via the receiving groove 25, which runs longitudinally along the telescopic sight adapter 3. On both sides of the receiving groove 25, radially outwardly projecting connecting webs 26 with inclined outer contact surfaces 27 are arranged in the rear area.

[0020] As from Figure 4 As can be seen, the cover flap 5 functions in accordance with Figure 1In its rearward-folded open position, the cover flap 5 acts as a bridge piece engaging with the connecting webs 26, connecting the two connecting webs 26 and preventing the receiving groove 25 from widening when the clamping device is actuated. When the cover flap 5 is in the position described in the Figure 1 and 4In the open position shown, folded back, the two connecting webs 26 engage in the dovetail groove 10 of the cover flap 5 when the clamping section 14 of the telescopic sight adapter 3 is slid onto the cover flap 2 via the hinge part 6. The dovetail groove 10 in the cover flap 5 is dimensioned such that the inclined outer contact surfaces 27 of the two connecting webs 26 come into contact with the inclined inner side surfaces 11 of the dovetail groove 10 when the telescopic sight adapter 3 is slid onto the cover flap 2. The cover flap 5, which acts as a bridge, stabilizes the clamping section 14 around the mounting groove 25, so that when the cocking lever 24 is closed, the clamping section 14 is not deformed in the area of ​​the mounting groove 25, but only in the area of ​​the longitudinal gap 15, thereby generating sufficient radial force for cocking.

[0021] The scope attachment adapter 3 described above is not only compatible with a Figure 2 The scope cover shown (2) can be used. It can also be mounted on a scope with a differently designed scope cover or on a scope without a scope cover. For example, a [missing text] can be used as a bridge piece to cover the mounting groove 25 and to connect the two connecting webs 26. Figure 5 The mounting rail 28 shown, with a mounting profile 29 designed, for example, as a Picatinny profile, or a mounting profile 29 designed in Figure 6The illustrated lid-shaped cover 30 serves as a mounting rail. Additional attachments, such as infrared heaters or the like, can be mounted on the mounting rail 28. Both the mounting rail 28 and the lid-shaped cover 30 have a dovetail groove on their underside, corresponding to the groove 10, for positive engagement with the connecting webs 26. The mounting rail 28 or the cover 30 can be slid onto the connecting webs 26 and held securely, yet releasably if necessary, by a snap-fit ​​connection.

[0022] In Figure 7A cover slider-shaped insert 32 is shown, which can be inserted into the dovetail-shaped groove 10 of the cover flap 5. This allows the groove to be concealed when the telescopic sight cover 2 is used without a telescopic sight adapter 3. A knurled surface or other suitable structure 33 can be provided on the outside of the insert to simplify the mounting and dismounting of the insert 32. Reference symbol list
