ROLLING PREVENTER FOR GRENADES

Abstract

A rolling preventer for reducing rolling movements of a grenade, wherein the rolling preventer has at least one hindering element, which counteracts rolling movements of the grenade and can consequently reduce the rolling movement. The rolling preventer according to the invention also has a clearance, by which the rolling preventer can be attached to a grenade. For this purpose, the grenade is inserted through the clearance and the rolling preventer is thereby fastened to the grenade. Also proposed is a grenade, with a housing, an actuating element and a safety device, wherein the grenade is equipped with a rolling preventer according to the invention.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

[0031] FIG. 1 shows a grenade according to the invention with a corresponding rolling preventer;

[0032] FIG. 2 shows a rolling preventer according to the invention in side view; and

[0033] FIG. 3 shows a rolling preventer according to the invention in plan view.

DETAILED DESCRIPTION

[0034] FIG. 1 shows a grenade 10 according to an exemplary embodiment of the invention, with a housing 11, an actuating element 12 and a safety device. The housing 11 of the grenade 10 here has a round base area, whereby the housing 11 is likewise designed as round.

[0035] The actuating element 12 is designed here as a hand lever, since the grenade 10 in FIG. 1 is a hand grenade. Preferably, it is a stun grenade that is designed as a hand grenade.

[0036] The safety device can be formed of a safety ring 13, to which a safety pin 14 is attached. The safety pin 14 secures the position of the hand lever, and consequently prevents unintentional activation of the grenade. By pulling on the safety ring 13, the safety pin 14 can be pulled out of its position, and consequently the function of the hand lever can be released.

[0037] Provided as a peripheral region on the housing 11 of the grenade 10 is a safe region 15, in which no blow-out openings for the deployment of the active charge of the grenade 10 are arranged. Preferably, this safe region 15 is arranged at the lower end in the region of the bottom of the grenade.

[0038] A rolling preventer 1 according to the invention may be attached to the grenade 10, in that it is arranged in the safe region 15.

[0039] For this purpose, a through-clearance is provided within the rolling preventer, so that the rolling preventer 1 has a peripheral contour around this clearance. By means of this peripheral contour, the rolling preventer 1 is attached in the safe region 15 of the grenade 10 such that the grenade 10 is inserted through the clearance.

[0040] For this purpose, the rolling preventer 1 is preferably formed elastically, so that the grenade 10 can be inserted into the clearance of the rolling preventer 1 with a press fit. The rolling preventer 1 is then fastened to the grenade 10 as a result of the elasticity.

[0041] In order then to prevent or reduce a rolling movement after throwing or launching of the grenade 10, at least one hindering element 2 is attached to the rolling preventer 1. This element is designed such that it counteracts a rolling movement or ensures a resistance to the rolling movement. In this way, the rolling movement of the grenade 10 is reduced.

[0042] In FIG. 2, the clearance 5 in a rolling preventer 1 according to the invention is shown. The clearance 5 is designed as passing right through, so that a hole can be seen in the rolling preventer 1. Preferably, the clearance 5 is formed centrally around the center axis 3 of the rolling preventer 1.

[0043] In order to apply the rolling preventer 1 better to the grenade 10, the outer walls of the clearance 5 are designed as beveled, so that a bevel 6 is produced. This makes it easier to attach the rolling preventer 1 to a grenade 10, since the grenade 10 can then be inserted into the side with the greater diameter, and the aforementioned press fit of the rolling preventer 1 takes place by way of the side with the smaller diameter of the clearance 5.

[0044] Preferably, the maximum height 8 of a rolling preventer 1 according to the invention is limited, for example to 10 mm, so that it is ensured that no elements on the grenade 10 that are intended to make a deployment of the active charge possible are covered by the rolling preventer 1 according to the invention.

[0045] At least one hindering element 2, which is intended to hinder or reduce a rolling movement of the grenade 10, is provided on the rolling preventer 1 according to the invention. These hindering elements 2 are preferably designed in one piece with the contour 4 of the rolling preventer 1 and may be arranged at regular intervals and also at irregular intervals around the contour 4.

[0046] In FIG. 3, these hindering elements 2 can be seen more clearly. In this exemplary embodiment, two hindering elements 2 are arranged around the contour 4. For this purpose, the hindering elements 2 are designed as rectangular and provided with slight roundings 7. By this design of the hindering elements 2, a rolling movement of a grenade 10 is prevented. The extent to which a rolling movement is prevented can be adjusted by the roundings 7 or the geometrical design of the hindering elements 2.

[0047] In order to ensure effective reduction or prevention of the rolling movement, the hindering elements 2 must have a greater outside diameter than the grenade 10 that is used.

[0048] The present invention is not restricted to the aforementioned features. Rather, further designs are conceivable. Thus, a rolling preventer according to the invention could be produced from soft, deformable metal, the work of deformation as a result of the rotational energy causing a reduction of the rolling movements of the grenade at the hindering elements. Similarly, snap-in connections, whereby the rolling preventer according to the invention is attached to the grenade, could be provided for a more precise positioning of the rolling preventer according to the invention.

[0049] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
