Description

The present invention relates to a net launch device. Such

  This device is intended especially for guards and veterinarians to capture or neutralize dangerous animals in natural parks, zoos, kennels.

  It is also intended for guards and agents responsible for the protection of restricted areas, in order to prohibit access to malicious or particularly aggressive people. Several launcher devices currently coexist on the market: - devices such as that of the patent TRECHOT GB 1007949 implement launching arrows and weights deployment of the net, which is imprecise and dangerous. devices such as that of the patent SUAI FUMIO JP 2003125697 implement deployment weights of the net launched by fronds, which is also imprecise and dangerous; - Devices require the launch of a container cylinder that is detonated in the air under the action of a compressed gas so that it releases a net, which is imprecise and dangerous in case of malfunction; devices such as that of the patent MB ASSOC GB 1309362 implement complex cartridges hosting a net.

  These devices are not without a number of other disadvantages, and the need to have a specific launcher. In order to overcome these various problems, the object of the invention is to propose a device, a net launch device, comprising a hollow cylindrical launcher tube. According to a first major characteristic of the invention, this launcher tube is capable of accommodating: first and foremost, a pneumatic or pyrotechnic propulsion means such as a cylindrical cartridge containing, on the one hand, powder, and on the other hand a inert material, - secondly and in full, an indispensable cylindrical intermediate skirt whose upper and lower surfaces are preferably adapted to cooperate with the surfaces of the two neighboring bodies, - thirdly and in part, a net carrier shell, this shell being able to contain a net. This arrangement makes it possible to launch the net carrier shell with a cartridge of a current model. According to another characteristic of the invention, this cartridge also houses a ball made of organic material of the rubber type. -2- This ball makes it possible to shock the target which will then be easier to cover with the net. According to another characteristic of the invention, this skirt has flexible O-ring protuberances.

  According to another characteristic of the invention, this shell is constituted on the one hand by a flank whose cylindrical lower part is adapted to be positioned in the upper part of the light of this launcher tube, and on the other hand a domed hat. This geometry makes it possible to position in the launcher a hull whose dimensions far exceed those of the diameter of the light of the launcher. According to another characteristic of the invention, this sidewall consists of several lateral parts joined by their sides as well as their base. According to another characteristic of the invention, this net being of polygonal shape, each of its vertices is connected by a hanger to the base of one of these side pieces. The hull is composed in part by the weight of the net, which allows to lighten its content. According to another characteristic of the invention, these lateral parts having weaker binding zones on their sides than on their bases, they separate first when throwing by their sides and come to form a silhouette in bloom, before to separate by their base and to open progressively this net under the effect of the pressure of the air. The aerodynamic shape of these parts makes it possible to obtain a less unpredictable effect than that of flyweights.

  According to another characteristic of the invention, this net has four corners and said shell has four side pieces. According to another characteristic of the invention, this net locally contains a marker such as a liquid or solid paint intended to mark the target. According to another characteristic of the invention, the device is compatible with many types of TUB launching tubes. This contributes to simplicity and speed of implementation. The features of the invention mentioned above in a nonlimiting manner will appear more clearly on reading the following description of a preferred embodiment. This description is made in connection with the attached drawings, among which: FIG. 1 is a view of the net launch device in longitudinal section, FIG. 2 is a view of the net carrier shell in horizontal section, FIG. Figure 3 is a view of the net after casting. FIG. 1 represents a preferred embodiment of said device DIS launches net. Said device comprises a hollow cylindrical TUB launcher tube housing in its light: first and foremost, a pneumatic or pyrotechnic propulsion means, ideally a cylindrical CAR cartridge, secondly and in full, an indispensable cylindrical intermediate JUP skirt, thirdly and in part, a shell COQ net holder. Said cylindrical cartridge CAR contains on the one hand powder POU, and on the other hand an inert MAT material that can associate wad and air. It implements a plastic sleeve with a reinforced thickness in order to avoid the bending of said sleeve during the return on load. It also hosts in the warhead of its projectile preferably in pure latex molded a BIL ball made of plastic organic rubber-type material. Said intermediate skirt JUP has two upper surfaces SUS and lower SUI preferentially able to cooperate with the surfaces of the two neighboring bodies. Its role is to ensure a good maintenance of said shell COQ at the beginning of throwing, the components of said shell COQ must not be dissociated before the total output of said launcher tube LAN. It also has on its cylindrical flank JUC TOR1, TOR2, TOR3 flexible O-ring protuberances. Said cylindrical flank JUC has a thickness homogeneous to that of the sleeve of said cylindrical cartridge CAR.

  Said COQ shell contains a thread FIL. It consists on the one hand of a flank FLA whose upper part PIS is flared and whose lower part PIC is cylindrical, and on the other hand a domed cap CHA. Said lower part PIC is able to be positioned in the light of said launcher tube TUB. Said flank FLA consists of several side pieces LAT1, LAT2, LAT3, LAT4 joined by their sides as well as their base. The junction is made by gluing so that the junction of said sides is less resistant than the junction of said bases. Said lateral pieces LAT1, LAT2, LAT3, LAT4 are shown in horizontal section in FIG. 2. Said thread FIL is introduced into the volume constituted by said FIA flank before occlusion by the laying of said curved cap CHA. Said thread FIL being of polygonal shape, each of its vertices SOM1, SOM2, SOM3, SOM4 is connected by a -4- hanger SUS1, SUS2, SUS3, SUS4 to the base of one of said side pieces LAT1, LAT2, LAT3, LAT4, This connection can be achieved by devices not shown hooks permanently ensuring the link between said suspension lines SUS1, SUS2, SUS3, SUS4 and said side pieces LAT1, LAT2, LAT3, LAT4 which constitute after the launch of aerodynamic deflectors by their shape and weight. Said hook devices may also momentarily provide the link between said lines and said JUP skirt at the start of the pitch as long as said JUP skirt is inside said LAN starter tube, the separation occurring later. For reasons of simplicity of implementation of said device DIS, said thread FIL has four vertices SOM1, SOM2, SOM3, SOM4 and said shell has four side pieces LAT1, LAT2, LAT3, LAT4. Said side pieces LAT1, LAT2, LAT3, LAT4 having weaker binding areas on their sides than on their bases, they separate first when throwing by their sides and come to form a silhouette in bloom. They then separate by their base and move away from each other, which has the effect of opening gradually under the effect of air pressure said net FIL. The IDF thread then falls on the target who is trapped after being shocked during the impact of the rubber ball. Said hat CHA is relatively flat and integral with the central zone of said thread FIL. It accepts a reversal of shape after the throw. It is possible to have the lateral pieces LAT1, LAT2, LAT3, LAT4 of different masses if it is desired to have a sloping angle of said thread WIRE.

  Said thread FIL locally contains a marker MAR, preferably near or in contact with said hat CHA. It can be a liquid or solid paint intended to mark the target. In addition, said DIS device is compatible with any type of TUB launching tube of caliber greater than or equal to 12 gauge, for example a 12mm shotgun, a 40mm grenade launcher. In the case of the implementation of this device for animal captures, as performed in zoological reserves, it is conceivable to make a specific LAN launcher tube. Said LAN launcher tube can integrate an external sound moderator for better capture conditions.

The embodiments of the invention presented above have been chosen because of their practical nature. It would not be possible, however, to exhaustively list all the embodiments covered by this invention. In particular, any means described may be replaced by equivalent means without departing from the scope of the present invention. 10 15 20 25 30 35
