DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to portable equipment for immobilising personal firearms during test firing, comprising a baseplate secured to an existing holder and bearing a plate pivotable around a first axis and receiving a rail mounted for tilting on the plate around a second axis perpendicular to the first, the rail receiving at least two gun locks slidable along its axis and having slides perpendicular to the rail axis, a U-shaped holder being mounted in the slide of each gun lock in order to receive the firearm for adjusting.
A known stabilisation device conforms to the definition hereinbefore (FR 93 05 371).
Although excellent for stabilising of adjustments around axes, the device is relatively complicated to operate and more particularly is too slow for series adjustment of firearms.
Also, the device has to be adjusted and locked by using tools, and access for locking is required to places which are sometimes hidden by the firearm positioned in the holders.
The object of the invention is to provide a portable device or equipment for immobilising personal firearms during test firing, the device being particularly simple to operate, requiring little adjustment and locking, and being relatively light and easy to install while ensuring extremely stable adjustment and locking.
SUMMARY OF THE INVENTION
To this end the invention relates to equipment of the kind defined hereinbefore, characterised by a joint connecting the baseplate to the rail and comprising: tilt correcting shaft carried by the baseplate, means of a tilting member, baseplate, to the rotation shaft, element on to the rotation shaft, relative to the head and pulling it against the bearing surface of the intermediate component, component, the slide being received for sliding in the intermediate component, intermediate component in order to pull and lock the rail via the head against the bearing surface of the intermediate component, and intermediate component and between the rail and the intermediate component.
The equipment comprises a reduced number of clamping points, and clamping tools are not required. Clamping by means of the cam or cone-effect clamping means is very simple and very fast, operation is simplified, but the equipment has excellent stability both in positioning and in adjustment.
According to other advantageous features of the invention: a bore receiving the rotation shaft and the arms are formed with a bore for the pivoting shaft and comprise a circular arcuate slide centred on the shaft for enabling the component bearing the clamping member extending through the slide to pivot around the shaft for adjusting the angle. slide of the connecting element, intermediate component and its head bearing on the top of the component in order to clamp the component against the connecting element and lock the latter on to the shaft. the cavity in the rail, wall of the rail, forming a bearing for tilting around the shaft, intermediate component, and means having a cam surface co-operating with a corresponding surface of the slide for pulling it and locking the rail against the bearing surface of the intermediate component; a frusto-conical surface displaced in the direction of the cone axis by screwing the clamping member into the intermediate component. fitted between the intermediate component and the baseplate and comprising two threaded rods ending in an assembly eyelet and received in a threaded sleeve, the threaded rods having opposite threads, like the sleeve. component and bearing against the top and the bottom of the rail on either side of the shaft, and at a distance therefrom. opposite threads and a screwing sleeve, the members bearing laterally between the rail and the baseplate.
The various components constituting the equipment are simple mechanical parts which do not break easily, and are easy to manufacture and assemble. The installation also comprises a large number of commercial components, which simplifies problems of maintenance and holding of stocks.
