Definitions

• the invention relates to a device for controlling the kinematics of doors which must open simultaneously or almost simultaneously to allow free passage, in particular for an application relating to a submarine equipped with a gun-launching tube.
• a massive front door located between the thick hull of the submarine and a thin hull, and able to withstand the immersion pressure ensures the closure of the tube, sea side.
• the thin hull has in the axis of the front door a breach for the passage of weapons leaving the torpedo tube; the breach is closed by a bow flap at rest.
• the weapons are in principle wire-guided. Wire guidance is provided by a wire of appropriate length, which is protected by a flexible metal sheath. This sheath is vulnerable to friction on the sharp angles presented by the edges of the breach. To avoid damaging the duct, a part called the duct guide is installed on the bow breach, put into service when the front door is opened. This piece translates, pivots to fall back on an edge of the breach.
• the front door Before launching a weapon outside the weapon launcher tube, the front door, the bow flap must be opened simultaneously or almost simultaneously, and the sheath guide folded down. This clears the space for the passage of the weapon. This space is commonly called “clear passage”.
• the front door is moved by a hydraulic press.
• the bow shutter moved by a so-called “main” kinematics linked to the front door disappears from its initial position while the sheath guide moved by a so-called “secondary” kinematics linked either directly to the front door or to the shutter. bow folds over an edge of the breach.
• the opening of the front door leads on the one hand to the opening of the bow flap and the commissioning of the duct guide, on the other hand to the opening of an air distributor on the air circuit of launch of the weapon.
• the object of the invention is to provide a device for controlling the kinematics of elements liable to form an obstacle to passage.
• the invention therefore relates to a device for controlling the kinematics of pivoting elements which must open in rotation simultaneously or almost simultaneously to allow free passage, in particular for doors and other pivoting elements capable of forming an obstacle to passage.
• a weapon in a weapon launcher tube equipped with a circuit for launching the weapon via an air distributor on board a submarine characterized in that it comprises on the axis of rotation of each pivoting door or element, and on the axis of rotation of a rotary element connected to the air distributor, means for transforming a rotation into translation, means for transforming a translation into rotation, associated means for quantifying these transformations, the means for transforming a translation into rotation along the axis of rotation of the rotary element being implemented by the means for transforming into translation a rotation along the axis of rot ation of each door or pivoting element in association with the quantification means.

• the quantification means consist of a piston connected to the rack.
• the device according to the invention can be connected to a control assembly for the opening of the air distributor, the opening actually occurring only if it corresponds to a predetermined value of rotation for the rotary element in relation to the air distributor.
