Underwater hunting crossbow with an elastic arming mechanism. This type of crossbow comprises an elongate body the rear end of which is provided with a stock fitted with a trigger, and the front end of which is provided with a head to channel and propel an arrow using lateral elastic ties for propulsion the front ends of which are attached or held to said head, and the rear ends of the elastic ties are connected to an arming device configured to catch on a peg or a nock situated at the rear of the arrow. The greatest disadvantage with this type of crossbow is that it can be armed only on the pegs or the nocks. The tension in the elastic ties is therefore constant because it is dictated by the distance separating the pegs or the nocks from the head. The solution proposed by the invention is an underwater hunting crossbow characterized in that the arming device incorporates clamping elements, which elements are able to move between an active position in which they clamp the body of the arrow and a passive position in which they release the body of said arrow, said clamping elements being in an active position as soon as the elastic ties are tensioned to arm the crossbow. Thus, when arming the crossbow by stretching the elastic ties, the arming device is positioned by clamping at any point on the arrow. Not only is it possible for the arrow no longer to have either pegs or nocks, but the hunter can adjust the tension in the elastic ties. |
