  • the aiming device comprises means for measuring or detecting the threshold of the slope, and means for correcting scrolling as a function of the slope measured.
  • the first actuation of said chronometry and display control member causes the display of a first scroll mark in the viewfinder at a relatively large distance from the reference mark, then, successively or simultaneously, the display of a second scroll mark at a relatively short distance from the reference mark.
  • the aiming device consists of different sub-assemblies represented symbolically in FIGS. 2 and 3. It essentially comprises a telescope 120 providing a view of the terrain and of the target with a certain magnification, which can be by example three to five, and comprising a sighting reticle 1 simulated with the optical axis and the emission axis of a telemetry laser 102.
  • the telemetry laser 102 can itself be separated from the telescope, or , preferably, use common optical parts with the telescope.
  • a display device 105 for example based on light-emitting diodes, associated with a semi-reflective blade 123 (fig. 4) makes it possible to show in the field of the telescope 120 different marks and the line of rise which will thus be displayed on the reticle 1.
  • the telescopic sight 120 can be conventional with a lens 121, a rectifier prism 122, a reticle 124, and an eyepiece 126 with its ring 127. However, a separating blade 123, a lens 128 and a plane mirror 125 are added in order to to allow the projection, on the reticle, of the various marks of the display member 105, as indicated above.
  • the display device 105 may consist of a mosaic of light points 4 arranged in the form of a matrix (FIG. 3).
  • the display device 105 then comprises an electro-luminous plate associated with a liquid crystal mosaic.
  • the display device 105 comprises two bars arranged in a cross, each consisting of a plurality of light-emitting diodes2, 3.
  • the diodes 2 of the first bar are aligned on along the site line 31 parallel to each other and to the central headline 32.
  • the diodes 3 of the second strip are themselves distributed along the headline 32 parallel to each other and to the line site 31.
  • the diodes 2 of the first strip will allow the display of markers 21, 22 for measuring the target running speed while the diodes 3 of the second strip are intended to allow display of rise marks 33.
  • the sighting device of Figures 2 and 3 further comprises a computer 101, formed for example from a microprocessor, used in particular for determining the location of the various marks to be displayed using the display device 105 based on the input data supplied to the aiming device by the operator or by the sensors associated with the device.
  • a computer 101 formed for example from a microprocessor, used in particular for determining the location of the various marks to be displayed using the display device 105 based on the input data supplied to the aiming device by the operator or by the sensors associated with the device.
  • An ambient temperature sensor 103 is preferably added to the sighting device to improve the accuracy of the calculation of the rise.
  • a slope sensor 107 which can be an accelerometer, but is preferably a level with contacts constituting a threshold detector operating by gravity (for example with mercury) in order to reduce the cost and d '' increase reliability.
  • This level with contacts can naturally be doubled with an air bubble level, visible by the operator, in order to allow the latter to be placed on a slope which is substantially zero before the start of the firing sequence.
  • the signals supplied by the slope sensor 107 can also be used to control automatic scroll correction means as a function of the measured slope.
  • a sensor 111 for measuring the ambient illumination can be added to the aiming device to make it possible to adjust the power supply of the display device 105 so as to keep constant the ratio between the luminance of the displays and the background luminance.
  • the optional temperature measurement 103 and tilt measurement sensors 107 are connected by analog-digital converters 109, 110 respectively to the computer 101.
  • interface circuits 108, 106 are arranged respectively between the rangefinder 102 and the display device 105 on the one hand, and the computer 101 on the other hand.
  • Memories 104 for recording a calculation program and various parameters are also associated with the computer 101.
  • a timing device 112 and control buttons 113, 114 also complete the sighting device of FIGS. 2 and 3.
  • the major drawback of this arrangement lies in the fact that, in this case, the measurement times are very variable according to the distances, that is to say are very short for short distances with high target speeds, and excessively long for long distances with low target speeds, which therefore affects intervention time.
  • the present invention recommends adapting the position of the scrolling marks displayed 11, 12 with respect to the headline 32 (fig.1b) in order to obtain an optimized measurement time which is neither too long so as not to penalize the intervention time, or too short so as not to affect precision.
  • This adjustable character of the position of the adjusted scroll marks constitutes an essential characteristic of the present invention.
  • the presence of scrolling marks 11, 12, of adjustable position displayed selectively in the viewfinder makes it possible in particular to predetermine the time for measuring the running speed of the target.
  • a telemetric distance measurement is carried out in the first place (fig la)
  • the scroll marks will be far from the line of sight; for larger distances, the scroll marks will be closer to the center line.
  • FIGS. 6b and 6c combines the advantages of a solution with a pair of marks 11 or 12, namely the simplicity of the operating mode, the shooter having in his field of vision only an end mark. of movement with respect to which it must observe the displacement of the target, and those of the solution with two pairs of marks 11, 12, namely the reduction of the tachymetry time in the case of slow movements.
  • An additional precaution may consist in interrupting the display of the scroll marks 11, 12 or 13 after a maximum duration of tachymetry, for example equal to 2 s, indicating to the shooter that if the internal mark 11 (dimension X 1 ) is not reached by the target 5 at the end of this time, the lateral speed of the latter is very low and the correction of tachymetry is considered to be left to its appreciation.
  • the duration of intervention by the shooter to measure the target's running speed (tachymetry) will therefore be limited to the maximum authorized duration.
  • the measurement of target distance is not carried out at the start of the operations but at the end of the sequence ( FIGS. 8d and 9d), which allows a shorter time between the laser emission capable of making the shooter locate, and the launching of the projectile (fig 8e and 9e).
  • the scroll marks 52 respectively 12 are first displayed in a fixed manner for a predetermined time at a fixed distance y respectively y ' 0 relatively distant from a fixed reference mark 42 respectively 32, which can be engraved, then move (marks 53 resp. 13) to the reference marks 42 resp. 32 to decrease the angular interval between the start marks 42 resp. 32 and end of scrolling 53 resp. 13 (dimension y1 in FIG. 8b and y'1 in FIG. 9b) and minimize the tachymetry time.
  • scroll marks 11, 12 which can be adapted to the distance from the known target of the computer 101 from the information provided by the rangefinder 102 (FIG. 1b), and intended to allow a measurement of target running speed with maximum precision and convenience in a limited time, are displayed in viewfinder 1.
  • the computer 101 thus controls the display, on the other hand and on the other side of the central vertical line 32 of the reticle, of a vertical fixed mark 12 which can become mobile 13 (fig 6b and 6c and fig 9a to 9c) or of several, preferably two, fixed vertical marks 11, 12 (fig 1b), called scroll marks, by addressing the corresponding display elements 2 or 4 of the display device 105.
  • the bodies 113b, 113a for triggering telemetric shooting and timing and display triggering are preferably coupled or combined in a single operating button 113.
  • the tachymetry sequence with display of the scroll marks and the start of the chronometry can be initialized without delay as soon as the rangefinder is triggered, which itself instantly provides an indication of target distance.
  • a single operating button can also be used, a first actuation causing the triggering of timing, a second actuation causing the timing to stop and a third actuation causing the triggering of telemetry.
  • a reset button is associated with the system in order to be able to reset an aiming sequence.
  • the shooter After displaying the scrolling marks, the shooter keeps his weapon stationary and observes the movement of the target 5.
  • the shooter stops the timing operation by actuating a contact 113a provided for this purpose, or, more simply, in the case where this contact is combined with rangefinder control button 113b, by pressing or releasing this button.
  • the chronometric end marks 52 are initially coincident with the headline 32 (FIG. 8a) or arranged symmetrically with respect to the headline 32 in the vicinity thereof, and then move towards the outside of the field (marks 53 of FIG. 8b) in the direction of the fixed reference marks 42.
  • These marks 52, 53 of FIGS. 8a to 8c are thus similar to the above mentioned marks 12, 13.
  • the telemetry is carried out after having finished the chronometry (fig 8d and 9d).
  • the laws of displacement of the scroll marks 53, 13 are predetermined and do not involve the distance, but can produce, if necessary, displacement speeds which increase as a function of time.
  • the computer 101 knows the distance from the target, the running time of the target for the angle corresponding to the running marking 11, 12, 13 or 53 considered, the flight time of the projectile that it determined according to the firing parameters which are mainly the distance from the target and the ambient temperature, and possibly the superelevation, measured or detected compared to a threshold by the sensor 107.
  • the computer 101 determines the horizontal angular offset of the aiming point to be displayed in order to make a shot at a future goal, possibly corrected for the superelevation. It also calculates the vertical angular offset corresponding to the increase.
  • the scroll marks 11, 12 or 13 are then erased and shot marks 21, 22 or 23 are then displayed by addressing display elements 2 or 4 closest to the calculated positions, from the discrete ramps available (fig 1d, 6d, 8e, 9e) (dimensions X ' 1 , X' or X ' 3 ). If it has not already been, the rise mark 33 is also displayed by addressing the display elements 3 or 4 closest to the calculated positions.
  • the device uses the display of two scroll marks 11, 12 on each side of the central line 32 (FIG. 1b, 1c) there are two possible scroll speeds corresponding to the measured scroll time. It will therefore also be displayed, on each side of the central line 32, two firing marks 21, 22 (fig 1d, 1e) corresponding to the two possible scrolling speeds.
  • the operator chooses the firing mark (for example mark 22 in fig.1d) in correspondence with the internal or external scroll mark used (for example mark 12 in fig 1c).
  • the projectile firing operation is carried out as follows: The shooter repoints his weapon so as to place the target 5 at the intersection of the lines displayed by the sight mark horizontal 33 and the vertical shot mark, adequate 22 or 23 (fig 1e and fig 6e, 8e, 9e).
  • the appropriate vertical shot mark is located to the left of the central line 32, the target scrolling to the right and is constituted by the outside mark 22, the mark for measuring the scrolling used being the outside mark 12.
