Gun accessory mounting device

1. A gun accessory mounting device, characterized in that the accessory is connected to an adapter,

that said adapter is provided with a gripping means, and

that said gripping means comprises a spring biased clamping mechanism and a counter stay cooperating with said clamping mechanism, wherein a distance between a pressure plate and a lever of the spring biased clamping mechanism is reduced when the accessory is pivoted from a first position to a second position; and

wherein said counter stay comprises a shackle handle adapted to a trigger guard of the gun.

2. Mounting device, characterized in accordance with claim 1 , wherein said adapter is provided with retaining means for the accessory, said retaining means being pivotably connected to said clamping mechanism for clamping said clamping mechanism when said accessory is pivoted.

3. Mounting device in accordance with claim 1 , wherein said clamping mechanism comprises the lever, a rod connected to said lever, a pivoted clamping arm connected to said rod and the pressure plate spring biased against said lever, and wherein said rod is biasing said pressure plate when the clamping arm is rotated.

4. Mounting device in accordance with claim 3 , wherein a spring is provided between the lever and the pressure plate for biasing said pressure plate when the clamping arm is stretched.

5. Mounting device in accordance with claim 3 , wherein said rod is movable between a first released position and a second locked position in which the rod is locked by a spring biasing effect.

6. Mounting device in accordance with claim 3 , wherein a manually controlled locking device is provided on said adapter and said rod is movable between a first released position and a second locked position in which the rod is locked by the locking device.

7. An accessory for mounting on a gun, characterized in that the accessory comprises a lamp rigidly connected to an adapter,

that the adapter is provided with gripping means,

that said gripping means comprises a spring biased clamping mechanism and a counter stay cooperating with said clamping mechanism, wherein a distance between a pressure plate and a lever of the spring biased clamping mechanism is reduced when the accessory is rotated from a first position to a second position, and

that said adapter is provided with a switch for turning said lamp on and off.

8. An accessory in accordance with claim 7 , wherein said clamping mechanism comprises the lever, a rod connected to said lever, a pivoted clamping arm connected to said rod and the pressure plate spring biased against said lever, and wherein said rod presents a load on the pressure plate when the clamping arm is rotated.

9. An accessory in accordance with claim 8 , wherein a manually controlled locking device is provided on said adapter, and said rod being movable between a first released position and a second locked position in which the rod is locked by the locking device.

10. An accessory in accordance with claim 7 , wherein said switch comprises a magnetically controlled switching element and a magnet that can be moved in relation to the switching element.

11. An accessory in accordance with claim 10 , wherein said magnet is rigidly connected to a sliding and spring bias shaft.

12. An accessory in accordance with claim 11 , wherein said spring bias shaft is displaceable between a first resting position, in which said switching element opens a circuit, and a second resting position, in which said switching element closes a circuit.

13. An accessory in accordance with claim 12 , wherein said spring biased shaft is resiliently displaceable between said first resting position and an instable position in which said switching element closes a circuit.
