1304409 Tripod support for firearms HECKLER & KOCH GmbH 24 July 1970 [30 July 1969] 36055/70 Heading F3C A tripod support for firearms has a frame 1 having legs 8 displaceable thereon, each leg having detent means which comprises a toothed ring 21 mounted on a bearing 12, Fig. 2, and a toothed ring 22 mounted on a head member 15 of the leg 8, and each leg having a release lever 31 for controlling the engagement of the detent means. The bearing member 12 supports an axially displaceable pivot pin 13, Fig. 3, which connects the frame to the respective leg 8. The lever 31 has a displaceable abutment member 35 having an arm 38 engageable with the pivot pin 13 to effect axial displacement thereof and having an arm 40, Fig. 4, which facilitates the rotation of the member 35 about a pin 36 and against the action of a spring 43, so as to move the arm 38 out of engagement with the pivot pin 13 and thus allow the lever 31 to rest inoperatively against the respective leg. The pin 13 is screw-threaded at 14, Fig. 3, and has a bush 18 screwed thereon. A spring 20 is positioned between a flange 19 of the bush 18 and a flange 17 of the head member 15. The lever 31 is pivotally connected to the member 15 by means of a pin 33 and a spring 34 is located between a portion 32 of the lever 31 and the member 15. In use, when the arm 38 of the member 35 is in line with the pin 13 as shown in Fig. 4 and the lever 31 is moved into alignment with the leg as shown in Fig. 2, the teeth of the rings 21, 22 disengage and allow the leg to be moved into a different angular position. The lever 31 is then released, the spring 20 moves the lever to the position shown in Fig. 3 and the teeth of the rings 21, 22 re-engage. The member 35 is rotated by means of the arm 40 thereof so as to disengage the arm 38 from the pin 13 and allow the lever 31 to be moved by means of the spring 34 into the position shown in Fig. 2. One leg 8 is connected to an angle member 2, Fig. 1, and two legs 8 are each connected to the member 2 via a tube 4. A weapon carrier 5 is supported by means of a fork 6 which is rotatably mounted on the member 2 and by means of an adjuster device 7 which is displaceably supported for vertical and lateral adjustment on an aiming guide 3 carried by the tubes 4. |
