DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a safety device for rifles having a housing which accommodates a breech body and having an operating part which is arranged on the butt grip and is operatively connected to a catch for a release plunger which is loaded, when the breech is cocked, by the force of a firing pin spring, and in the case of which items a breech holder is provided in the vicinity of the catch, can be lowered against the force of a spring and engages in a guide groove in the breech body.
A safety device of this generic type has been disclosed in AT-PS 388610. In the case of rifles equipped with such safety devices or rifles equipped with known similar safety devices, there is room for improvement with regard to safety and operating convenience. The breech body can be removed and fitted again only when the weapon safety catch has been released. If this is done with the magazine fitted and a cartridge is fed in when the breech body is inserted, the rifle is not in a safe state. In order to operate the breech holder, it is necessary either to press the trigger or to operate a further control element close to the trigger. There is thus a risk of incorrect action.
The object of the invention is therefore to overcome the defects mentioned above in such safety devices and, furthermore, to improve the operating convenience.
SUMMARY OF THE INVENTION
The forgoing object is achieved according to the invention wherein: element and to a slide rod, a first transverse pin, which case, in the safe state, the first stop edge is located against the stop surface, and the second stop edge is located against the first transverse pin, and transverse pin in the breech holder in such a manner that, in a further safe position of the operating part, the breech holder is lowered.
The safety element acts on the catch and on the breech holder. Thus, when the operating part is in the safe position, no shot can be discharged, and the breech holder cannot be lowered when the safety catch has been released. The slide rod is used to operate the breech holder. The slide rod lowers the breech holder when, for example, the operating part is moved to a further safe position. All the safety functions can thus be controlled from the operating part. Since the safety element and slide rod may be flat sheet-metal parts, the space requirement and manufacturing cost are low.
The double function of the safety element can be achieved particularly easily if it is a two-armed lever which can rotate about an axis located somewhat under the first stop edge, and whose rear end has a slot which is guided on a pin in the operating part, and at whose front end the second stop edge is located. The sliding guidance in the slot allows the pin on the operating part also to be used at the same time for connection to the slide rod, even if, advantageously, the safety element is arranged on one side of the breech holder and the slide rod is arranged on the other side of the breech holder (claim 3).
In an advantageous development of the invention, the breech body has a first circumferential tab, and the slide rod has a third stop edge, which fixes the first circumferential tab in the further safe position of the operating part, so that the breech body cannot be moved to its unlocked position (claim 4). The slide rod thus also carries out a second function in addition, by which means a further safety gap is closed.
Furthermore, it is within the context of the invention for the breech body to have a second circumferential tab which is shorter in the longitudinal direction than the first circumferential tab and rests against the operating part of the third stop edge when the breech body is in the safe-for-transportation position and the operating part is in the further safe position (claim 5). The additional safe-for-transportation position of the breech body can be provided in various ways, for example as described in the simultaneously submitted Patent Application WO 97/47941 from the applicant. It can be moved to this position only when
