Claims
- 1. A trigger related safety device for a firearm comprising a main trigger and a secondary trigger which is incorporated with the main trigger so that the secondary trigger is movable with the main trigger when the main trigger moves in a first direction when squeezed to fire the firearm, or in a second opposite direction when released; the secondary trigger being reciprocally movable relative to the main trigger between a first or operative and a second or inoperative position; and a locking member associated with the secondary trigger which, when the secondary trigger is in the said operative position, serves positively to lock the main trigger to a stationary part of the firearm so preventing the main trigger from moving in said first direction; and when the secondary trigger is in the said inoperative position, the main trigger is free to move with the secondary trigger in said first direction; the said locking member comprising an elongated pin having a longitudinal axis which extends transversely the said first and second directions, the pin being slidably moveable in at least one direction which extends parallel to the pin's longitudinal axis between a first position when one end of the pin engages a complementary catch formation on said stationary part of the firearm when the secondary trigger is in the said operative position to a second position where said one end of the pin is disengaged from the catch formation when the secondary trigger is in said inoperative position.
- 2. The device of claim 1 wherein the secondary trigger includes a transversely extending first slot which has a bore in which the pin is received for its said movement, and the main trigger includes an aperture through which the end of the pin can extend in order to engage said catch formation on the stationary part of the firearm.
- 3. The device of claim 1 wherein the secondary trigger includes a transversely extending first slot which has a bore in which the pin is received for its said movement; and the main trigger includes an aperture through which the said one end of the pin can extend in order to engage the said catch formation on the stationary part of the firearm, the said first slot having a bore which is of oval configuration in cross section, the pin also including along its length at least one transversely extending spigot, and the secondary trigger including a second elongated slot which has two ends and which has a bore which extends at an angle relative to the said first and second directions, which bore communicates with the said bore of the first slot; the said spigot being slidable in the second slot so that when said spigot is moved along the second slot from said one end of the second slot to the other end of the second slot, the pin is caused to move from its said first to second positions.
- 4. The device of claim 3 wherein the said spigot extends on both sides of the pin and the secondary trigger includes a further slot similar to the said second slot located in a diametrically opposed face of the secondary trigger so that the slots can each slidably accommodate opposite ends of the spigot.
- 5. The device of claim 4 wherein the secondary trigger is of substantially T-shape in plan comprising an elongated head and an elongated stem which extends transversely from the head, so that it has a free end remote from said head, the head furthermore having an upper face defining a trigger engagable surface and the stem including said first, second and further slots.
- 6. The device of claim 1 wherein the main trigger includes an aperture extending right through it in a direction parallel to that of said first and second directions; the secondary trigger being received slidably in the aperture to be movable therein between the said operative and inoperative positions.
- 7. The device of claim 1 wherein the main trigger includes a blind hole into which a coil spring may be received for effecting a biasing action on the main trigger in the said second direction.
- 8. The device of claim 1 including a spring which biases the secondary trigger towards its said operative position.
- 9. The device of claim 1 including a spring which biases the main trigger in the said second direction.
- 10. The device of claim 1 whereto the secondary trigger includes a transversely extending first slot which has a bore in which the pin is received for its said movement; and the main trigger includes an aperture through which the said one end of the pin can extend in order to engage the said catch formation on the stationary part of the firearm, the said first slot having a bore which is of oval configuration in cross section, the pin also including along its length at least one transversely extending spigot, and the secondary trigger including a second elongated slot which has two ends and which has a bore which extends at an angle relative to the said first and second directions, which bore communicates with the said bore of the first slot, the said spigot being slidable in the second slot so that when said spigot is moved along the second slot from said one end of the second slot to the other end of the second slot, the pin is caused to move from its said first to second positions; and wherein said spigot of the pin is accommodated in the bore of said transversely extending first slot provided in the body of the secondary trigger; and wherein the secondary trigger is of substantially T-shape in plan comprising an elongated head and an elongated stem which extends transversely from the head so that it has a free and remote from said head, the head furthermore having an upper face defining a trigger engagable surface, and the stem includes said first and second slots; and wherein the main trigger includes an aperture extending right through it in a direction parallel to that of said first and second directions; the secondary trigger being received slidably in the aperture to be moveable therein between the said operative and inoperative positions; and wherein the said aperture in the main trigger has two ends, one of which is of such dimension that it can snugly receive the said head of the secondary trigger slidably and the other end of the aperture being of such dimension that it can snugly receive said free and of the stem slidably, the two ends of the aperture being separated by two opposed holders in the aperture which each defines a seat for one end of an elongated coil spring which can bias the secondary trigger towards its operative position, the other end of the coil spring engaging the head of the secondary trigger adjacent the stem of the secondary trigger.
