Anchoring harpoon intended in particular for an aircraft and anchoring system including one such harpoon

摘要

The invention relates to an anchoring harpoon intended in particular for an aircraft, capable of cooperating with an anchoring grate (2) of a platform, comprising jack means (3) including cylinder means (4) containing mobile piston means (5) provided with a rod (6) that extends beyond the cylinder means, the free end of which includes a harpoon head (7) that is hooked in the grate (2) and comprises retaining fingers (8, 13, 14) that can be moved between a retracted position and an active position by control means (9). The invention is characterised in that the cylinder means (4) include at least two telescopic cylinder portions (10, 11) which can move between a position in which one portion is retracted inside the other and an active position in which one portion projects out from the other.

主权项

1. An anchoring harpoon intended in particular for an aircraft, capable of cooperating with an anchoring grate of a platform, comprising;
a jack including a cylinder containing a mobile piston supporting a rod that extends beyond the cylinder, the free end of the rod includes a harpoon head configured to be hooked in the grate and the harpoon head comprises retaining fingers that can be moved between a retracted position and an active position by a controller, wherein the cylinder of the jack includes at least two different telescopic cylinder portions, a lower portion in which the mobile piston is installed and moves and an upper portion, which can move between: a passive position in which the lower portion is retracted inside the upper portion such that the harpoon is folded and occupies a minimum amount of space; and an active position in which the lower portion projects out from the upper portion, corresponding to an anchoring configuration of the harpoon head in which the harpoon head is to be anchored in the grate, and wherein the jack is configured to keep the cylinder portions in their passive position by default, and to move the telescopic portions from their passive position to their active position to deploy the harpoon head relative to the upper portion of the cylinder for anchoring the harpoon head in the grate.
