摘要 The firearm is fixed on its support by springs passing through aligned orifices formed in elements rigidly fixed respectively to the firearm, to a brake borne by the support and stops serving as a support for the return springs. The invention is useful for small and medium calibre firearms, particularly for preventing firing until the weapon is correctly secured on its support.
权利要求
1. An assembly comprising a support and an automatic weapon of open breech-block type, adapted to be mounted on said support, said weapon comprising a mobile breech-block subjected to the force of at least one return spring bearing via its rear end against a plug slidably mounted in the rear portion of the weapon breech box, characterized in that the bearing plug is fixed in relation to the weapon breech box and the weapon is fixed on its support by associating with each bearing plug of the return spring a detachable fixing member which, when the bearing plug of the return spring occupies its normal firing position and the weapon occupies its normal position on its support, is adapted to move through aligned apertures with which three separate attaching elements provided to this end are formed - i.e., a first element connected to the bearing plug, a second element connected to the weapon, and a third element connected to that member of the support to which the weapon is to be fixed, and further comprising a shock-absorbing apparatus with a mobile fitting interposed between the weapon and its support, characterized in that the attaching element associated with the weapon support is mounted towards the rear of said mobile fitting.
2. An assembly as set forth in claim 1, characterized in that the three attaching elements are disposed at a level situated towards the rear of the weapon.
3. An assembly as set forth in claim 1, characterized in that the weapon is secured on its support by disposing the attaching element associated with the weapon slightly in front of the bearing plug of the return spring; so arranging the attaching element associated with the bearing plug that it extends forwardly as far as the level, forming the securing level of the attaching element associated with the weapon; so arranging the attaching element associated with the weapon support that it extends rearwardly as far as the securing level; and so shaping the three attaching elements that their respective portions disposed at the securing level are so superimposed that they can be formed with aligned fixing apertures through which the fixing member shared by the three attaching elements can be engaged.
4. An assembly as set forth in claim 1, wherein characterized in that the attached element associated with the bearing plug is disposed in the most distant position on the side by which the fixing member is engaged - i.e., below the two other attaching elements - when such member is vertically engaged downwards, thus further increasing the securing of the weapon.
5. An assembly as set forth in claim 4, characterized in that the attaching element associated with the weapon is formed by a simple perforate lateral foot extending transversly of the weapon axis, the attaching element associated with the supporting member on which securing is to be carried out, takes the form of a longitudinal clevis with perforate fins adapted to fit over said perforate foot which is thus engaged between such fins, and the attaching element associated with the plug takes the form of a perforate fin connected to the plug and occupying a position beneath the lower fin of said clevis (the fixing member being supposed to be vertical and engage from top to bottom).
6. An assembly as set forth in claim 1, wherein angular wedging means are provided for wedging the bearing plug in relation to the weapon breech box, so that the alternating angular stressings to which the bearing plug is subjected during firing are not transmitted to the weapon securing device as a whole during firing.
7. An assembly as set forth in claim 6, characterized in that said angular wedging means are formed by a protuberance disposed on the periphery of the bearing plug and a recess of corresponding shape with which the periphery of the recess provided for the bearing plug is performed, the protuBerance engaging in the recess when the bearing plug occupies its operative position.
8. An assembly as set forth in claim 1, wherein the fixing member is formed by a simple spindle having a head at one end and axial retaining means at the other end.
9. An assembly as set forth in claim 8, characterized in that the axial retaining means are resilient locking means incorporated in the spindle.
10. An assembly comprising a support and an automatic weapon of open breech-block type, adapted to be mounted on said support, said weapon comprising a mobile breech-block subjected to the force of at least one return spring bearing via its rear end against a plug slidably mounted in the rear portion of the weapon breech box, characterized in that the bearing plug is fixed in relation to the weapon breech box and the weapon is fixed on its support by associating with each bearing plug of the return spring a detachable fixing member which, when the bearing plug of the return spring occupies its normal firing position and the weapon occupies its normal position on its support, is adapted to move through aligned apertures with which three separate attaching elements provided to this end are formed - i.e., a first element connected to the bearing plug, a second element connected to the weapon, and a third element connected to that member of the support to which the weapon is to be fixed, and wherein the attached element associated with the bearing plug is disposed in the most distant position on the side by which the fixing member is engaged - i.e., below the two other attaching elements - when such member is vertically engaged downwards, thus further increasing the securing of the weapon, the attaching element associated with the weapon being formed by a simple perforate lateral foot extending transversely of the weapon axis, the attaching element associated with the supporting member on which securing is to be carried out, takes the form of a longitudinal clevis with the perforate fins adapted to fit over said perforate foot which is thus engaged between such fins, and the attaching element associated with the plug takes the form of a perforate fin connected to the plug and occupying a position beneath the lower fin of said clevis (the fixing member being supposed to be vertical and engage from top to bottom).
11. An assembly comprising a support and an automatic weapon of open breech-block type, adapted to be mounted on said support, said weapon comprising a mobile breech-block subjected to the force of at least one return spring bearing via its rear end against a plug slidably mounted in the rear portion of the weapon breech box, characterized in that the bearing plug is fixed in relation to the weapon breech box and the weapon is fixed on its support by associating with each bearing plug of the return spring a detachable fixing member which, when the bearing plug of the return spring occupies its normal firing position and the weapon occupies its normal position on its support, is adapted to move through aligned apertures with which three separate attaching elements provided to this end are formed - i.e., a first element connected to the bearing plug, a second element connected to the weapon, and a third element connected to that member of the support to which the weapon is to be fixed, and wherein angular wedging means are provided for wedging the bearing plug in relation to the weapon breech box, so that the alternating angular stressings to which the bearing plug is subjected during firing are not transmitted to the weapon securing device as a whole during firing.
12. An assembly as set forth in claim 11, characterized in that said angular wedging means are formed by a protuberance disposed on the periphery of the bearing plug and a recess of corresponding shape with which the periphery of the recess provided for the bearing plug is performed, the protuberance engaging in the recess when the bearing plug occupies its operative position.
