Description

Title of the invention: Safety device and visualization device for a safe angle of fire, particularly for hunting, and its method of implementation

[0001] The invention relates to a safety and visualization device for a safe angle of fire, in particular for hunting.

[0002] Safety regulations for hunting, particularly driven hunts, require hunters in their stands to define safety angles to their right and left in relation to the most exposed neighboring element, such as their neighbor, a house, etc. The safety angle in France is 30°. Most often, each safety angle is determined by taking five steps in the direction of the element to be protected, then three steps perpendicularly, and the angle is then marked with a stick.

[0003] However, this measure remains approximate, which can be considered insufficiently safe.

[0004] There is also a flag system that can be attached to watchtowers.

[0005] However, these so-called proximity devices (step method or flag system) materialize the angles over a small distance, which is not so reliable.

[0006] Furthermore, a device described in patent application FR3080675 or in patent application EP3978861 is known, which uses two laser beams that are fixed and angularly separated by 30°. By pointing one of the beams in the direction of the element to be protected, the user then visualizes the predefined angle of 30° thanks to the second beam.

[0007] However, these prior art devices are operated by the user while holding them in their hand. Yet, even a slight movement by the user while locating the element to be protected can distort the safety angle. Furthermore, the user must be careful to clearly visualize the beam that is always closest to them in order to locate the firing limit line, which is not always without risk if the user is not sufficiently attentive; they may, in fact, mistake the other beam (the beams being fixed in a V shape). Moreover, this device is unsuitable if the user requires a different safety angle value.

[0008] The invention therefore aims to provide a safety and visualization device for a safe firing angle, which overcomes the aforementioned disadvantages and is easy and quick to implement.

[0009] The invention applies to delimiting a shooting zone and securing the environment, both for shooting with firearms and with bows.

[0010] According to the invention, the safety and visualization device for a safety angle for shooting, in particular for hunting shooting, comprises a housing which contains at least one system for generating at least one light beam in the range of visible wavelengths, the beam exiting the housing being capable of delimiting a safety angle for shooting relative to a reference line, the device being characterized in that the beam is angularly movable while the housing remains fixed and in that the beam adopts a first position which corresponds to the reference line and a second position which is offset by the safety angle relative to the first position (the first position then no longer being visible).

[0011] Therefore, according to one feature, the device includes a single beam which serves (firstly) as the reference (line of) the obstacle and (secondly) as the reference (line of) the firing safety angle relative to the obstacle.

[0012] The device therefore uses only a single beam to determine the firing angle to the left or right of the obstacle. Thus, the shooter cannot make a mistake; they consistently visualize the firing zone because only one beam remains visible on one side of the user, unlike prior art devices that generate two beams on one side of the user, which can lead to confusion. The device of the invention directly materializes the firing zone by defining the inner safety zone, which is delimited between the shooter and the single visible beam (to their right or left) generated by the device.

[0013] Furthermore, the device of the invention makes it possible to adapt to any position where the obstacle to be secured is located, whether several shooters are posted in a line or when an object or person to be secured is at an angle to a line of post.

[0014] Furthermore, the device, with its laser beam, and especially when installed at a height, can reach up to fifteen meters, allowing the user to obtain a visual reference point much further away than the immediate proximity reference points of prior art systems. In addition, this provides a much more distant view of the firing zone.

[0015] Preferably, the beam illuminates between 500 and 590 nm.

[0016] In the following description the term "height", the qualifiers "upper", "lower", "top" and "bottom" of an element of the device are used in the context of a normal installation of the device, that is to say relating to a vertical notion in relation to a horizontal reception surface on which the device would be placed.

[0017] According to one feature, the device includes at least one suitable form of attachment for installing the device in a fixed and elevated position in its operating position, in particular for installing it on a height-adjustable mounting bracket such as a tripod or other suitable mounting bracket for attaching to an existing structure, such as a lookout tower. This way, the device can be easily fixed without risk of movement once installed (it is perfectly stable), and it can be put into operation with the assurance that the resulting beam will be reliable.

[0018] In a first configuration, the device comprises a single system for generating a single light beam. This configuration allows for a lighter device. The device is then used to delimit a safety angle either to the right or to the left of the shooter. Once the beam has illuminated the line of the safety angle, for example, to the user's right, the user can mark the angle by placing a stable physical marker, such as a stick, twig, or tree branch, on the ground at the beam's level. This marking can be done up to the end of the beam, particularly at a distance of about fifteen meters, which allows the safety angle to be visualized from a distance. The user then rotates the device to operate it on the other side, for example, to their left, by positioning the beam on the obstacle and then, by activating the device, rotating the beam to the safety angle.He will be able to visualize the beam and therefore the safe angle to his left.

[0019] In a second configuration, the device comprises two systems for generating two distinct light beams in the visible wavelength range, and the beams exiting the housing (after angular displacement of each) define two respective safety angles to the right and left of the device (i.e., a first safety angle relative to a first obstacle to be secured to the right of the device and a second safety angle relative to a second obstacle to be secured to the left of the device). This second configuration allows, with a single device, the visualization of the authorized firing zone along with the boundary lines to the right and left of the shooter.

[0020] In the second configuration, according to a characteristic, the two beams are angularly movable independently of each other, the angular displacement of each of the two beams being referenced with respect to a first reference position which has been given independently to each of the beams.

[0021] According to one feature, the device comprises, coupled to a beam generation system (and therefore coupled to the beam), a beam angular displacement system that is semi-automated, being manual via a user interface element such as a knob to be turned or pressed to establish the first position, and then automated to move directly from the first position to the second position without user intervention. Thus, the device is simple to manufacture (interface elements and electronic control means) and simple to implement, while also being reliable. Indeed, the user has control over the interface element. to target exactly the obstacle to be secured, and is then assured that the firing limit beam will be in the right place without risk of having the wrong angle.

[0022] Therefore, according to one feature, the device comprises, coupled to a beam generation system (and thus coupled to the beam), a beam angular displacement system, which is automated to move from the first beam position to the second beam position. In this way, once the obstacle is detected, the user cannot make a mistake since it is the device itself that generates the visualization of the second beam position corresponding to the safety angle, which is pre-recorded in the device's electronic processing and control means.

[0023] According to one feature, the device comprises electronic processing and control means and an actuation system, the electronic processing and control means being capable of: - to angularly displace (in the beam exit plane) the beam in response to a voluntary actuation of the actuation system up to the first position corresponding to the reference line, - record this first position and automatically move the beam angularly by a safe angle, in particular 30°, from the first position to the second position, and - lock (in particular in an automated way) the second position.

[0024] According to one feature, the device includes electronic processing and control means for the operation of the device and user interface buttons, preferably touch buttons, connected to the electronic processing and control means, the buttons including an on / off button, and for a beam, three buttons including a first reset and validation (SET) button, a second button controlling the angular rotation of the beam in a direction of rotation such as clockwise, and a third button controlling the angular rotation of the beam in an opposite direction of rotation such as counterclockwise,Preferably, the first beam position corresponding to a reference line is automatically saved when the user releases the button they pressed to adjust the angular position of this first position and immediately afterwards presses the first reset and SET button (in this case to validate the first position), which automatically generates the angular rotation of the safety angle to the second position.

[0025] Alternatively, in another semi-automated operating mode, the device may include a first button to be turned manually to angularly move the beam, and a second push button to validate the first reference position (once the first knob has been turned to the reference position), the second beam position is then automatically generated by angular displacement of the beam from the first position to the second position according to the predefined safety angle.

[0026] According to one feature, the second position is offset from the first position by a pre-recorded angle of 30° (the device is designed with this value of 30° pre-recorded at the factory), or the device may include an interface for voluntarily and previously defining the safety angle and recording it.

[0027] According to one feature, the device includes at least one distribution output of said at least one beam, which is oriented by being inclined towards the opposite of the upper surface of the housing (i.e. inclined downwards and towards the ground in the position of use).

[0028] Advantageously, the device includes a housing level indicator, in particular the indicator is a bubble level.

[0029] According to one feature, the device includes a battery, preferably cooperating removably with the housing, and a battery charge level indicator, preferably visible on the top (upper face) of the housing.

[0030] According to one feature, the device includes a safety system for cutting off the beam, or even cutting off the power supply to the device, in the event of angular tilt of the device relative to its horizontal plane of use. In particular, the housing includes at least one tilt sensor, and the safety cut-off system is integrated into the electronic processing and control means that process the data from the tilt sensor. Preferably, the beam is cut off as soon as an angular tilt of 15° is detected, and the power supply is cut off as soon as an angular tilt of 30° is detected. Thus, if the device tilts forward or backward during handling, the beam is immediately cut off, preventing any risk of burns, particularly to the eyes of the user.

[0031] The invention also relates to an assembly comprising the aforementioned safety device of the invention, and a mounting support for raising the device to a higher position, such as a tripod or a support adapted to be fixed to an existing elevated structure, in particular a hunting blind, preferably the support being removable from one face of the housing, such as the so-called lower face of the housing, the device comprising at least one suitable form of attachment to the support. The hunting blind support for a hunter positioned in a hunting blind or the tripod support for a hunter positioned on the ground provides stability to the assembly and therefore to the safety device, thereby enhancing the effectiveness of the adjustment of the safety device.

[0032] The invention also relates to a method of implementing the aforementioned safety device of the invention, the method according to a preferred example comprising the following steps: - fixed installation of the device facing a user; - commissioning of the device, the device comprising several user interface elements including at least two buttons with clockwise and counter-clockwise rotation function; - Pressing one of the beam rotation function buttons generates a beam with a distribution output on one side of the device and the user, and rotates the beam until it aligns with an obstacle such as 01 to be secured, and optionally pressing the other rotation function button rotates the beam in the opposite direction until it aligns perfectly with the obstacle, the beam then being aligned in the first position; - Pressing a validation button validates (saves) the first position, which automatically generates the angular displacement (around a vertical axis) of the beam to the second safe angle position relative to the first alignment position with the obstacle to be secured; -optionally, the user repeats the same actions for the other side of the device and therefore the other side of the user if the device has another system for distributing a second beam, or if the device has only one beam distribution system, having turned the device around so that the beam is delivered to the other side.

[0033] The present invention is now described by means of purely illustrative and in no way limiting examples of the scope of the invention, and from the accompanying illustrations, in which: - [Fig. 1] shows a perspective view of a safety and viewing device for a safe firing angle according to a first configuration of the invention, and of a tripod-shaped support for mounting the device at a height. The first configuration allows a safe viewing angle to be displayed to the left or right when the device is installed. - [Fig. 2] shows a perspective view of a safety device and a display of a safe firing angle according to a second configuration of the invention. The second configuration allows for the simultaneous display of a safe angle to the left and a safe angle to the right when the device is installed. - [Fig.3] is a bottom view of the device of [Fig.2] with the battery removed. - [Fig.4] is a top view of the device in [Fig.2]. - [Fig.5] is a schematic longitudinal cross-sectional view of the device in [Fig.2]. - [Fig.6] illustrates a schematic view of the implementation of the device of [Fig.2]. - [Fig.7] represents a perspective view of the security device of [Fig.1] coupled to an installation support mounted on an existing fixed structure such as a watchtower.

[0034] The IA or IB device of the invention, for safety and visualization of a safety angle for shooting, in particular for hunting shooting, illustrated in the figures, provides at least one light beam in the range of visible wavelengths, this beam being angularly movable preferably in an automated manner between a reference position which is aligned with the object or person to be secured (hereinafter referred to as obstacle) and a position corresponding to the safety angle a, for example of 30°, with respect to the reference position.

[0035] A single beam serves first as a reference beam by aligning with the object or person to be protected, and secondly as a beam for determining the angle of safety.

[0036] Fig. 1 illustrates a first configuration of the AI ​​device with the provision of a first beam to delimit a first safety angle.

[0037] Figures 2 to 6 illustrate a second configuration of the device IB with the provision of a first beam and a second beam to delimit with the same device, two respective safety angles, an angle a to the left and an angle a to the right taking into account two obstacles, one to the right 01 of the user and the other to the left 02. As illustrated in [Fig.6], whatever the location of the obstacle 01 to be secured on the right and the obstacle 02 to be secured on the left, even if these two obstacles are not aligned, the device 1 of the invention will be able to easily, and preferably in an automated manner, delimit the safe firing zone which corresponds to the inner zone (schematically speckled) between the two beams Fl (angle of 30° to the left of the right obstacle 01) and F2 (angle of 30° to the right of the left obstacle 01).

[0038] Therefore, it comprises a single-beam distribution block 10. The second configuration of the IB device comprises two distribution blocks 10 and

[0039] The device IA, IB comprises a housing 2 and preferably a height-adjustable mounting bracket 1' such as a tripod ([Fig. 1]) or a bracket adapted to be fixed to an existing fixed height structure M such as a lookout tower ([Fig. 7]). The bracket 1' makes the housing 1 fixed so that the user, by not having to carry the device, can be certain that the device will not move during measurements and that the safety angles will be reliable.

[0040] The housing 2 has a body of generally paraplepiped shape and comprises an upper face 20, a lower face 21, two first opposite lateral faces 22 and 23, and two second opposite lateral faces 24 and 25.

[0041] The housing 2 comprises, for the first configuration of the device 1, a single unit 10 for distributing a single beam.

[0042] The housing 2, in the second configuration of the IB device, comprises two distribution units 10 and 11, each with a single beam. The housing 2 in the second configuration of the IB device is oblong in shape, with the two distribution units 10 and 11 diametrically opposed. The distribution units 10 and 11 are located in the lower part of the housing. The distribution units 10 and 11 are in the same plane and diametrically opposed. The first distribution unit 10 delivers a single beam to the right in order to define a safety angle with respect to an obstacle located to the right of the user. The second distribution unit 11 delivers a single beam to the left in order to define a safety angle with respect to an obstacle located to the left of the user.

[0043] In addition, the housing 2 contains at least one beam generation system 3 for said light beam in the visible wavelength range, at least one beam rotation mobility system 4, electronic control means 5 for said at least one beam generation system 3 and for said at least one mobility system 4, and an actuation system 6 for controlling the control means 5. The housing 2 also contains a battery 7 for supplying power to said at least one beam generation system 3, said at least one beam rotation mobility system 4 and the electronic control means 5.

[0044] A single beam distribution unit 10, 11 comprises a beam generation system 3 housed internally within the casing, and a single beam distribution output 30, 31 respectively, opening to the outside of the casing. Therefore, the device IA in the first configuration comprises a single beam generation system 3 and a single beam distribution output 30. The device IB in the second configuration comprises two opposing beam generation systems 3 and two opposing beam distribution outputs 30 and 31. Each of the two distribution outputs 30, 31 is independent of the other in operation; that is, the beam from the first output 30 is angularly independent of the beam from the second output 31, and the positioning of one is independent of the positioning of the other.

[0045] The device IA, IB is intended to be installed at a height, with each beam delivered downwards. In the installed position of the device, each beam is thus delivered at an angle to the vertical and is capable of pivoting around the vertical to locate, by means of said beam, the limit beyond which the shooter is not authorized to fire. The device IA in its first configuration has its beam distribution unit 10, which includes at its lower end a beam distribution outlet 30, the distribution outlet 30 being oriented with an inclination in the direction opposite the upper face 20 of the housing (i.e. downwards in the installed position of the device). The second configuration IB device includes at the lower end of each of the beam distribution units 10 and 11, a distribution output 30 of one beam, and respectively a distribution output 31 of another beam, each of the distribution outputs 30 and 31 being oriented with an inclination in the opposite direction to the upper face 20 of the housing (i.e. downwards in the installed position of the device).

[0046] Each beam distribution system 3 is coupled to a rotational mobility system 4 (housed inside the casing). Each rotational mobility system 4 is capable of rotating the associated beam generation system 3 around an axis perpendicular to the flat upper face 20 of the casing, so as to angularly pivot the beam exiting the distribution outlet 30 or 31 from the reference position to the safety angle position. Each rotational mobility system 4 is designed to rotate the beam in one direction or in the opposite direction to adjust the reference position, and to rotate the beam in only one direction to move from the reference position to the safety angle position.

[0047] With reference to the schematic [Fig. 5], each rotating mobility system 4 comprises a motor 40, a rotating shaft 41 which carries the beam generation system 3 and is connected directly or indirectly to the motor 40 for its drive, and optionally a gear interface 42 arranged between the motor 40 and the rotating shaft 41 to adapt the rotational speed of the shaft 41, and therefore of the beam generation system 3, according to the motor speed and the available space inside the housing (which is designed to be as compact as possible). The motor 40 is designed to rotate in two directions to rotate the beam in one direction or in the opposite direction. The electronic control means 5 operate the motor 40.

[0048] The housing 2 is tiered, comprising in its lower part the distribution unit(s) 10 and 11 of a beam and above it the rotating mobility system(s) 4 (with their motor). The electronic control means 5 of the beam generation system(s) 3 and of the mobility system(s) 4 are an electronic circuit board housed inside the housing. In particular, the electronic control means 5 (the electronic circuit board) are located in the immediate vicinity of the upper face 20, just below it and inside the housing 2, so as to be directly electrically connected to the actuation system 6 arranged on the upper face 20. The actuation system 6 comprises several actuation elements (preferably of the touch-sensitive button type) located on the upper face 20 for user access.

[0049] With reference to [Fig. 4], the actuation system 6 comprises an on / off button 60, and for each beam distribution unit 10, 11, a reset and confirmation button 61 (“SET”), a first rotation button 62 for rotating the beam in one direction (e.g., clockwise), and a second rotation button 63 for rotating the beam in the opposite direction (counterclockwise). The rotation buttons 62 and 63 are touch-sensitive; pressing them with a finger rotates the beam clockwise for button 62 and counterclockwise for button 63. Actuating these rotation buttons 62 and 63 positions the beam in alignment with the obstacle to be secured, which corresponds to the first reference position.Once the user wants to validate the first position, they press the SET validation button 61, which automatically rotates the beam from the first reference position to the second safety angle position, specifically by rotating 30° in the opposite direction to the obstacle (beam Fl or F2 of [Fig.6]).

[0050] Advantageously, the upper surface 20 of the device includes, in particular at the level of the surface of the actuation system 6 which is connected below to the electronic board 5, a battery charge indicator 64 7.

[0051] The battery 7 is advantageously removable. The battery 7 is, for example, secured by snap-fitting. In the housing IA of the first configuration ([Fig. 1]), the battery 7 is accessible from a side face 25. In the housing IB of the second configuration (Figures 2 and 3), the battery 7 is accessible from the bottom face 21 and is positioned between the two distribution units 10 and 11 of a bundle.

[0052] The IA, IB device includes, directly on the housing or battery 7, a suitable mounting form for mutual cooperation by quick attachment with the support 1'. For example, the housing IA in the first configuration has, projecting from its lower face 21, a male form 26 adapted to mutually cooperate with a female form 1" of the support 1'. In the second configuration, the battery 7 of the housing IB, which is installed on its lower face, has a projecting male form 70 adapted to mutually cooperate with the female form 1" of the support 1'. The female form 1" of the support 1' is, for example, coupled to a spring-return clamping element that locks the IA or IB housing when the male form 26 of the housing or 70 of the battery has been inserted into the female form 1" of the support.

[0053] Advantageously, the device 1 includes, preferably on the upper surface 20, a leveling indicator 27 of the housing 2 and therefore of the device 1, in particular the indicator 27 is a bubble level.

[0054] Advantageously, the IA, IB device includes at the level of the housing body means for attaching a strap (the strap not being illustrated here) in order to facilitate the transport of the device.

[0055] Preferably, the housing contains at least one tilt sensor 50 ([Fig. 5]) and a safety cut-off system integrated into the electronic processing and control means 5 that handle the data from the tilt sensor. If the tilt exceeds a pre-recorded threshold value (for example, if the device tilts), the beam is immediately cut off.

[0056] The method of implementing the IB safety device for viewing firing angles will now be described with reference to [Fig.6].

[0057] The user installs the device permanently by positioning it facing them. They secure the device using the mounting bracket 70 on the support 1', for example. They press the start button 60. They first want to define a safety angle relative to an obstacle 01 (person, house, or other) located, for example, to the right. They press one of the rotation buttons, for example 61 corresponding to the right-hand unit 10 of the housing, to generate the beam at the distribution output 30 and to rotate the beam until it is aligned with the obstacle 01 to be secured to the user's right; if it has slightly overshot the obstacle, they press the second rotation button to rotate the beam in the opposite direction until it is perfectly aligned with the obstacle (schematically shown in dashed lines in [Fig. 6] between the device 1 and the obstacle 01).Next, the user does not press any further buttons, and after 5 seconds, the beam automatically rotates 30°. The adjustment is complete for the right side, and the single beam Fl on the right then defines the safety line beyond which firing is prohibited on the right. The user proceeds in the same way for the left side by pressing the rotation function button(s) 61 and 62 on the left-hand unit 11 of the housing to align the beam exiting the distribution output 31. Once the beam is aligned with the obstacle 02 (dotted line between devices 1 and 02), the beam automatically rotates 30° to define the single beam F2 on the left, which defines the safety line beyond which firing is prohibited on the left. The IB device has the advantage that, with a single unit, the shooter can see their authorized firing angle to the right and left (angle between Fl and F2).If the user wants to resume a measurement, they press the reset button 60 on unit 10 or 11 depending on whether the beam needs to be rematerialized on the right or left, before pressing one of the rotation function buttons 61 and 62 again.
