(10) The rear intermediate piece 6 can be moved substantially vertically relative to the rear ring base 7, where a bolt 17 is used to control the movement of the rear intermediate piece 6 relative to the rear base 7. A nut 18 is used for screwing and tightening.

(11) An adjustment device 19 is further arranged in connection with the rear intermediate piece 6 and the rear ring base 7, where the adjusting device 19 comprises a set or adjustment screw 20, a tightening or locking screw 21 and a spring 22.

(12) The design of the front and rear telescopic sight rings 2, 3, front and rear intermediate pieces 4, 6, front and rear ring bases 5, 7, and the adjustment device 19 manner of operation will be explained further in relation to FIG. 4.

(13) FIG. 2 shows the rear telescopic sight ring 3 assembled, where it can be seen that the upper half-ring 12 is formed with six through-going holes 23. Similarly, the lower half-ring 13 will be formed with six partially through-going holes 24, where these holes 24 are formed with threads. Screws 14 are used to connect the upper and lower half-ring 12, 13.

(14) The upper half-ring 12 is further formed with three sub-half rings 121, 122, 123 which are independent of each other, so that the rear telescopic sight ring 3 can be adapted more easily to different forms of a telescopic sight. The three sub-half rings 121, 122, 123 which are independent of each other may then be screwed individually relative to each other.

(15) It is seen further that the lower half-ring 13 on an inside is formed with six through-going holes 25, wherein the rear intermediate piece 6 is formed with a corresponding number of partially through holes 26, where these holes 26 are formed with threads. The lower half-ring 13 and the rear intermediate piece 6 will then be connected to each other by use of screws 11.

(16) FIG. 3 shows an embodiment of the device 1 for mounting and adjustment of a telescopic sight for a firearm which can be used to lift the device 1 up by one or more spacing plates 28 or spacers if one desires a higher mounting. The spacing plate 28 will be formed with the same number of holes 29 as the lower half rings 13 and the intermediate pieces 4, 6. When the lower half-ring 13, the spacing plate 28 and the intermediate piece 4, 6 are connected to each other through the screws 11, this assembly will be increased by the thickness of the spacing plate 28.

(17) The spacing plate 28 is further formed with grooves 30, so as to be received more easily in the rear intermediate piece.

(18) FIG. 4 shows the different elements of the device 1 for mounting and adjustment of a telescopic sight when disassembled.

(19) The front and rear intermediate piece 4, 6 is formed with a groove or recess 31, which groove or recess 31 is shaped complementarily to the groove 30 provided in the spacing plate 28, or a projecting portion 32 in the lower half rings 13.

(20) The front base 5 is formed on a top side with two flanges 34, where through each flange 34 there is provided a through-going hole 35. Further, the front intermediate piece 4 is provided with a through-going hole 36, which hole 36 is arranged such that it aligns with holes 35 in the flanges 34 when the front intermediate piece 4 and the front base 5 are arranged correctly relative to each other. The front intermediate piece 4 is further formed with rounded edges. The front intermediate piece 4 and the front base 5 will be connected to each other through bolt 15 and nut 16. This connection will also be a pivot for the front intermediate piece 4 when the device 1 for mounting and adjustment of a telescopic sight is to be adjusted.

(21) The rear base 7 is, in a similar way to the front base 5, formed with two flanges 34, where a through-going hole 35 is provided through each flange 34. The rear intermediate piece 6 will be provided with a recess 37, instead of a through-going hole as provided in the forward intermediate piece 4. The recess 37 is arranged such that it levels with the holes 35 in the flanges 34 when the rear intermediate piece 6 and the rear base 7 are arranged correctly relative to each other. The rear intermediate piece 6 and the rear base 7 will be connected with each other through bolt 17 and nut 18. Through this layout the rear intermediate piece 6 will be able to move vertically from the rear base 7.

(22) The adjustment device 19 provided in the rear intermediate piece 6 and the rear base 7 includes a spring 22 disposed between the rear intermediate piece 6 and the rear base 7, as the rear base 7, on a top side, will then be formed with a seat or groove 33 for receiving the spring 22.

(23) The set or adjustment screw 20, which at one end is formed with a tapering of between 15-50 degrees, for example 45 degrees, will, when screwed be pushed inwards against the spring 22 and engage a corresponding angled surface 61 provided internally in the intermediate piece 6, where this angled surface 61 is complementarily shaped with the tapering of the set or adjustment screw 20.

(24) When the set or adjustment screw 20 is tightened, the set or adjustment screw 20 will be guided along the angled surface 61 in the rear intermediate piece 6, so as to push the rear intermediate piece 6 downwardly. The rear intermediate piece 6 will be allowed this movement, as the recess 37 in the rear intermediate piece 6 will allow the rear intermediate piece 6 to be moved relative to the rear ring base 7. The at least one spring 22 disposed between the rear telescopic sight base 7 and the rear intermediate piece 6 will then be compressed. When the set or adjustment screw 20 is turned in the opposite direction, i.e. out, the set or adjustment screw 20 will be pulled away from the angled surface 61 provided in the rear intermediate piece 6, whereby the at least one spring 22 will push the rear intermediate piece 6 upwards.

(25) As the rear intermediate piece 6, due to the recess 37 can move freely relative to the rear ring base 7, the spring 22 will press the rear intermediate piece 6 up from the rear ring base 7, this movement resulting in that the front intermediate piece 4 will be rotated somewhat in relation to the front ring base 5. As the telescopic sight rings 2, 3 are connected to the front and rear intermediate pieces 4, 5, this will cause the telescopic sight to form an angle relative to a barrel of the firearm. When the desired angle is achieved, the tightening or locking screw 21 is used to lock the rear intermediate piece 6 in this position.

(26) When the desired alignment is achieved, a tightening or locking screw 21 is used to lock the rear intermediate piece 6 and the rear ring base 7 in a fixed position to each other, where also the bolts and nuts connecting the front and rear intermediate piece and the front and rear ring base can be used as a further lock of the telescopic sight's position.

(27) The front and rear base 5, 7 are also formed with two downwardly extending flanges 38, where one of these flanges 38 is formed with a groove on its inner side, so as to cooperate with a complementary groove provided in, for example, a Picatinny rail P. The clamp devices 8 may similarly be provided with a groove on their inner sides, so that the attachment of the front and rear base 5, 7 to the Picatinny rail P by means of clamp devices 8 provides a firm and locking connection.

(28) Only the elements relating to the invention are explained and described above and a skilled person will understand that the device for mounting a telescopic sight on a firearm can be designed with more or fewer elements which are assembled to each other. The skilled person will further understand that, within the scope of the invention as defined in the appended claims, more embodiments and modifications of the described and illustrated embodiments can be provided.
