Definitions

  • the object of the present invention is to ensure, as simply as possible, the automatic locking of a non-rolling hatch cover which may be of any of the so-called pontoons, folding, side-rolling types.
  • This locking can also result from a small movement of horizontal translation or close to a horizontal plane which ensures, on the one hand, the engagement of cleats of the panel under retaining tabs of the coaming and, on the other hand , tightening of seals, but this movement must be transmitted to the panel in a self-locking manner so that the panel does not have the possibility of unlocking spontaneously, for example under the effects of the sea.
  • blocking of the locking translation must thus fulfill the role of bracing filled by the winding winch in the case of rollable panels.
  • the present invention therefore consists in providing the association, with the coaming of each hatch, of at least one self-locking control mechanism intended to act on equipment of the hatch panel to impose on the latter, brought to a position close to closing, a complementary movement of horizontal translation of an amplitude of a few centimeters causing the locking of the panel and its watertight closing without the possibility of reverse actuation of the panel on the locking control so that any risk of spontaneous unlocking is excluded.
  • this self-locking locking control can be obtained by the use of at least one practically horizontal jack which is associated with the coaming and whose rod is articulated at the lower end of a connecting rod, the upper part of which pivots on an axis fixed to the coaming while the front and rear of the connecting rod constitute cams intended to cooperate with walls of the panel to ensure self-locking translations locking and unlocking.
  • the self-locking of the locking is ensured by a suitable profile of the cam part controlling the locking, this profile being established so as to achieve the bracing effect ensuring the desired self-locking as will be explained. below.
  • the proposed device requires only particularly simple equipment while being highly efficient and easy and quick to use.
  • the panel 1, shown schematically in Figures 1 and 2 is lowered on the coaming 2 to a position shown in Figure 2, close to the locked closed position, by the slings 3 suspended from a lifting device (not shown) .
  • a box welded to the panel and composed of front and rear walls 4-5, an upper wall 6 and a side wall 7.
  • On the internal faces of the front walls and rear 4-5 are respectively welded an adjusting shim 8 and a part 9 on which the cams act.
  • control of a connecting rod 10 intended to pivot on a transverse horizontal axis 11 carried by two vertical parts 12-13 welded to the coaming and arranged on either side of the connecting rod 10. Not only do these parts 12-13 support the connecting rod 10, but still they guide the panel 1 during the descent of the latter on the coaming 2.
  • the lower end of the connecting rod 10 is articulated at 14 to the rod 15 of a jack 16 associated with the coaming 2.
  • the locking is ensured by a small movement of horizontal translation of the panel 1 to the left of FIG. 2 as a result of the retraction of the jack 16 which inclines the connecting rod 10 forwards as shown in the FIG. 3, so that the front cam of the connecting rod 10 comes into contact with the shim 8 by pushing the panel to the left of FIGS. 2, 3 and 4.
  • This displacement has the effect of engaging the tabs 17 of the panel under the parts retainer 18 of the coaming as well as the joints 19 and 21 of the panel under the parts 20 and 22 of the coaming as shown in Figure 1.
  • the locking command which has just been described with reference to FIGS. 1 to 4 can be applied to a folding panel such as that shown diagrammatically in vertical section in FIG. 5 where the elements have also been indicated by the same reference numbers. which correspond to those of FIGS. 1 to 4.
  • the panel is made up of two folding parts 25-26 articulated to each other by an axis 27 on an edge of the part 25, the other edge of which is articulated at the coaming by a double hinge constituted by a connecting rod 28 articulated on the panel at 29 and on the coaming at 30.
  • the actuating cylinder 31 causes the connecting rod 28 is applied to the wall 32 of the panel.
  • the panel carries, as in the previous case, a box with walls 4-5-6 fitting onto the locking control device comprising the parts 12-13 and the connecting rod 10 as explained previously by causing the displacement to the left of the entire panel 25-26 thanks to the double hinge (or any other equivalent device), while the connecting rod 28 takes off from the wall 32 allowing a substantially horizontal translation of the panel during which the tabs 17 and the seals move to the locked closed position.
  • a locking command for the general structure described is also applicable to a panel of the so-called “side rolling” type, that is to say to be operated by lateral rolling, and such an application has been represented diagrammatically in FIGS. 6 to 9 of the drawing.
  • the panel indicated at 33 carries rollers 34 for rolling on transverse raceways 35 so as to come to 36 in the open position. This movement is effected by the action of a rack or an endless chain 37 actuated by drive pinions 38 and connected to the panel by an articulated arm 39. A panel stopper in position 17 has also been indicated. locking and it is understood that the drive of the chain makes it possible, by a movement to the right of FIG. 6, to release the tabs 17, after which the panel can be slightly lifted by the rise of the rollers 34 on the ramps 40-41 so that the seals cease to be compressed:
  • FIG. 7 shows that the connecting rod 10 is supported on the wall 44 when the panel is opened by transverse winding.
