DESCRIPTION:
BRIEF SUMMARY
The technical field of the present invention concerns accessory adapters for individual firearms including grenade launchers, laser gunsights, torches or any other aim-enhancing launch device.
It is well known how to affix various accessories to individual firearms. Each kind of accessory is outfitted with a specific and as a rule stationary adapter entailing modification of the weapon, in machining some parts of the weapon, and sometimes in eliminating original components. Furthermore accessory disassembly and re-affixation requires special tools not with the firearm operator when on maneuvers. In such a case the weapon is assigned to a specific use and it follows that the said adapter might be non-exchangeable.
The U.S. Pat. No. 4,580,362 describes a complex adapter used in affixing a laser gunsight onto a weapon composed of a very large number of parts accurately mating one another. This adapter entails the drawbacks listed below.
The great drawbacks of the above cited weapon modifications is that they are irreversible, rendering the weapon specific and entailing idiosyncratic management and maintenance constraints.
Another drawback is the specificity of each adapter, that is, there are as many adaptater designs as there are accessories.
Still another drawback is the need for a skilled gunsmith to adapt the weapon or to move it to its initial destination so that degradation be less than irreversible.
The object of the present invention is to create a weapon accessory adapter entailing only minimal weapon modifications and applicable to different types of weapons in order to circumvent the above cited drawbacks.
Accordingly the object of the invention is an aim-enhancing accessory adapter for an individual firearm, said adapter being located near the front part of the barrel and being characterized by comprising: component and the weapon barrel.
In a preferred embodiment mode of the invention, the stationary component on one hand is located away from the free barrel-end and on the other hand it is rigidly affixed to the weapon at the front end of tube enclosing said weapon.
In general the detachable component consists of a longitudinal plate fitted at one end with a connector to the stationary component and at the other end with hookup means to the barrel.
In one embodiment, the stationary component and the hookup means are fitted with a quick-connect means of the bayonet type, said hookup means comprising an aperture in the stationary component and a tang extending the hookup means, hookup being implemented by rotating the detachable component by a quarter revolution.
In still another embodiment, the hookup means is in the form of a hook with a bow and opening, said opening matching the barrel diameter, the hook being kept in place by a support ring of the weapon entering the bow.
In a variation, the hook is fitted with a complementary hook rotatable inside the bow and capping the barrel by means of the ring.
In particular the adapter of the invention is appropriate to affixing a laser gunsight or a grenade launcher.
A foremost advantage of the invention is that adapter use is simplified, no specific tool being required.
Another advantage of the invention is the faithful reproducibility of affixation of the accessory to the weapon.
Another advantage of the invention is that weapon performance remains undegraded.
Other features and advantages of the invention are elucidated in the following description of the embodiments of the invention in relation to the attached drawings.
FIG. 1 is a section of the front portion of a weapon and shows the adapter,
FIG. 2 is a perspective of part of the tube enclosing the weapon,
FIG. 3 is a perspective of the stationary component of the adapter,
FIG. 4 is a topview of the detachable component of the adapter,
FIG. 5 is a partial topview of the stationary component,
FIGS. 6A, 6B are sections of the hookup means,
FIG. 7 is a section of a play compensating system for the hookup means, and
FIGS. 8, 9 are two illustrative embodiments of how to affix accessories to a weapon.
