DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cocking and loading device for self-loading small firearms which are provided with a bolt movable in their longitudinal direction, in particular for an automatic rifle, with a pivoted cocking lever which extends in its rest position in longitudinal direction and can be transferred into an operating position by lateral pivoting, in said operating position a spring endeavouring to pivot the cocking lever forward and to retain it in the rest position exerts pressure on said cocking lever.
The German Patent 20 23 523 teaches a cocking and loading device by which the bolt of a weapon can be moved from its front position into a rear position, in the case of weapons which close on firing, in order to convey the bolt into the rear position so that it is caught by the triggering mechanism or that the bolt, when moving forwardly, introduces a cartridge into the barrel when the weapon is to be made ready to fire. In addition, it may be necessary to retract the bolt for clearing jammings. In order to ensure the back-movement of the bolt, the cocking and loading device is provided with a cocking lever which is transferred from its rest position into an operating position by pivoting, in this operating position the cocking lever passes through a slot which extends in the longitudinal direction of the weapon and projects the weapon laterally. This cocking lever which projects laterally serves the rifleman as a handle in order to retract the bolt. In order to avoid that this cocking lever is also actuated together with the bolt which runs back and forth during shooting and thus represents a considerable source of danger to the rifle man it is suggested not to mount the cocking lever directly at the bolt, but to attach it to a sliding element, so that the cocking movement can be transferred to the bolt via this sliding element which is movably arranged correspondingly to the bolt in the housing of the weapon and the cocking lever is disconnected from the cocking lever by means of the sliding element and thus from the movements of the bolt. Such solutions have the disadvantage that many parts are necessary which increase the weight, the time needed for maintenance, as well as the propensity for malfunctions of the weapon.
Because of the fact that the slide element associated with the cocking lever is not connected to the bolt of the weapon, but only abuts on the front side of the bolt, only the cocking movement for transferring the bolt into its rear position can be performed by means of this cocking and loading device, yet, e.g. in case of jamming or the like, when the bolt is trapped in a position between its front and rear position, these cocking and loading devices are not suitable for transferring the bolt into the front position, i.e. to serve as a closing means, because the slide element is not coupled with the bolt. Such a coupling can only be achieved by additional extensive means (DE-B-19 02 275).
Another disadvantage is that also in the case of a cocking lever abutting on the housing this lever usually projects over the surface of the housing (German Patent 20 23 523), which may be cumbersome in the use of the weapon, in particular when it is used in difficult terrain with thick undergrowth or when the weapon is held improperly when firing it.
Therefore it is the object of the present invention to avoid these disadvantages of the known cocking and loading devices and to provide a safe cocking and loading device by which the bolt can easily be moved into the rear as well as into the forward position.
The present invention solves this object by that fact that the cocking lever is accommodated in its rest position within the exterior contour of the weapon and arranged at the bolt directly or by means of an intermediate part.
The cocking and loading device according to the present invention comprises a cocking lever which is coupled to the bolt in that the cocking lever is either pivoted at the bolt directly or connected to the bolt by means of an intermediate part in a force-locking manner
