Abstract

Tripod for firearms, comprising a pivot support (1) having a vertical axis, to the flanges (5, 6, 7) of which are secured telescopical, adjustable legs (2, 3, 4), the first flange axis being horizontal enabling the leg (5) to be turned a vertical plane, the second (6) and third (7) flange axis being symmetrical to a vertical plane through the first leg and in a ground view, a front view and a side view being arranged in acute angles to the first leg axis, turning of second and third legs (6, 7) thereby amending the angles of those legs in the ground view in relation to the plan of the first leg (2), all legs having the same length. With a fourth, shorter leg (8) on the first leg the distance between the pivot support axis and the first leg's resting point on the surface may be decreased substantially when second (6) and third (7) legs being adjusted in a small acute angle for shooting at ground level in a direction substantially in the longitudinal axis of the first leg (2).

Description

Tripod for firearms

The present invention is related to a tripod for s firearms, according to the preamble of the claims. f Tripods for automatic firearms must be designed for easy transport and handling, furthermore they must easily and very quickly be installed and simultaneously such tripods should give a good support for the weapon during use. When firing such

10 weapon on targets in the air, there exists a strong demand for turning the weapon in all directions horizontally as well as inclined hereto. The tripod therefore should give substantially the same support in all directions.

Firing on targets at the ground level usually is is performed in the same direction and the tripod therefore preferably should be designed to give a maximum support for recoil forces in the opposite direction.

It is an aim of the present invention to provide a tripod having possibility for installation for firing shots on

20 targets in the air and also directionally firing at the ground level, thereby giving optimized support in both cases. This is achieved with the tripod according to the present invention as described with the features stated in the claims.

The drawing discloses in Fig. 1 a side view and Fig. 2

25 a ground view of the tripod installed for firing on targets in the air, Fig. 3 discloses a side view and Fig. 4 a ground view of the tripod installed for firing on targets at the ground level, Fig. 5 discloses a section along the arrow V in Fig. 7, Fig. 6 discloses a side view along the arrow VI in Fig. 7 and so Fig. 7 discloses a ground view of the pivot support of the tripod.

As disclosed in Fig. 1 and 2 the tripod according to the present invention comprises three legs 2, 3 and 4, all being telescopically extendable to a desired length or posistion. The

35 leg 2 is journalled on a horizontal shaft in a flange 5 fixed to the pivot support 1, enabling leg 2 to be turned in a vertical plan to adjust tha angle to the ground and the distance from the pivot support to the resting point on the ground. Legs 3 and 4 are journalled shafts on flanges 6 and 7 respectively fixed to the pivot support 1. Legs 3 and 4 thereby may be turned around symmetrically arranged axes arranged in an angle to a vertical symmetrical plan of the pivot support, with an angle C seen in said plan as disclosed in Fig. 5 and in relation to a plan perpendicularly to the symmetry plan, with an angle B as disclosed in Fig. 6, and finally with an angle A as disclosed in Fig. 7 in the ground view of the pivot support.

Legs 3 and 4 are journalled to the flanges 6 and 7 respectively, which legs 2, 3 and 4 may be adjusted such that the angle between two adjacent legs is 120°. For installing the tripod for firing on targets at the ground level corresponding to Fig. 3 and 4, the legs 3 and 4 are turned towards eachother which is made possible by the inclined position of their axes, the leges thereafter being fixed to the flanges 6 and 7. The leg 2 is turned correspondingly in a vertical plan around the axis of the pivot support 1 to a desired position. To ensure that the relatively long support of the leg 2 in front should not give vibrations, a support leg 8 is journalled to the leg 2 near the flange 5. The leg 8 is substantially shorter than the leg 2 and therefore provides a significant support of the tripod in the forward direction, whereas the two legs 3 and 4 receiving the recoil force, are situated relatively far behind the pivot support and relatively close to eachother.

Claims

PATENT CLAIMS

1. Tripod for firearms, comprising a pivot support having a vertical axis, the pivot support being secured prefer¬ ably to telescopical and adjustable legs being connected with the flanges to the pivot support, the axis of the first flange be horizontally in such a way that the leg secured to this flange may be turned a- vertical plane, and the axes of second and third flanges being arranged symmetrically to the vertical plane of the first leg, CHARACTERIZED IN the axes of second and third flanges in a ground view, a front view and a side view being arranged in acute angles to the plane of the first leg, in such a way that turning of second and third leg will amend the angles of those legs in the ground view in relation to the plan of the first leg, the three legs having the same length and the distance between the axis of the pivot support and the resting point on the surface may be decreased substantially when second and third legs being adjusted in an acute angle to eachother to ensure support by shooting at the ground level in a direction substantially in the longitudinal axis of the first leg.

2. Tripod according to claim 1, CHARACTERIZED IN a fourth leg having substantially shorter length than the other three legs, being connected to the first leg such that it can be turned downwards and create a support point substantially nearer the horizontal axis of the pivot support than the resting points of the other legs.

3. Tripod according to claim 1, CHARACTERIZED IN the length of the first leg may be decreased telescopically to a substantially shorter length than second and third legs to establish a resting point for the first leg substantially closer to the pivot support than the cases for second and third leg.
