Definitions

  • the present invention aims to provide automatic locking either in the closed position, or in the open position, or even in the two positions by the actuating cylinder, thereby eliminating the auxiliary short-stroke cylinder.
  • Document FR-A No. 2424398 describes an arrangement of hatch covers which are moved by means of actuating cylinders in open and closed positions. closing, and vice versa.
  • Securing devices are provided, such as the tabs carried by the panels and engaging under inclined retaining tabs. However, such means of securing retain the panels only in the vertical direction and they do not oppose the horizontal movements of the panel.
  • the actuating cylinders are actuated only during the closing and opening movements, but they are put to rest without pressure for the duration of the closing or of the opening, so that , without a lock making the connection between these jacks and the panels irreversible, the latter can, under the action of strong blades, especially in heavy weather, be subjected to forces having sufficient horizontal components to move the panels.
  • arrangement provided in document Fr-A No. 2424398 therefore does not offer any irreversible connection between the actuating cylinders and the panel, since the securing members cannot oppose the movement of the panel if the latter: is subjected to a force with a sufficient horizontal component capable of driving the actuating cylinders when these cylinders are at rest without being retained under pressure.
  • the document FR-A No. 2424398 provides (in FIGS. 2 to 4) with an ovalized hole to allow horizontal release of the securing members from the retaining tabs, but this ovalized hole is not provided for the connection of the actuator. operation with the fixed structure or with the panel, and it is in no way associated with a locking mechanism.
  • the device according to the invention for the automatic locking of a hatch cover in the closed or open position applied to a panel actuated irreversibly by an actuating cylinder is characterized in that the connection of the cylinder to the panel or to the fixed structure is effected by means of a device allowing a limited movement which is effected only under the action of the jack and which brings about a locking mechanism at least at the end of the stroke of the jack and unlocking at the start of the reverse stroke of this jack, the latter being able to act for an operation according to this reverse opening or closing stroke only after completion of the unlocking.
  • the invention is particularly applicable to panels established in a single pivoting element or in two elements, these panels being actuated by an actuating cylinder for their opening and closing.
  • the displacement means actuated at one stroke end of the actuating cylinder can be a simple guidance of the cylinder end to impose a small displacement of this end relative to the structure to which it is connected, this guidance being able to be provided by example by an ovalized hole provided at one end of the jack to receive the hitch pin of this jack end so that at one end of the stroke of the jack, the body of this jack can move along its axis to control a locking mechanism.
  • the means of displacement of an end of jack according to the invention can also be a short rod interposed between this end and the structure to which it is connected, so that the movement of the link, at one end, of stroke of the jack , ensures the operation of a locking mechanism.
  • the displacement means can also be established in the form of a toggle which is coupled to one end of the jack and which itself constitutes the irreversible locking mechanism thanks to the arrangement in. alignment of the two ends of the toggle joint at the end of the stroke of the jack which ensures the functioning of a locking mechanism.
  • the means of movement can also be established under.
  • the hatch is closed by a panel in two elements 1 -2 hinged together around an axis 3 and intended to be applied to the coaming 4 in the closed position.
  • the element 1 is articulated to the coaming via links 5 while the element 2 carries, at its end opposite the axis 3, rollers 6 intended to roll on raceways lateral 7 provided on the sides of the coaming 4.
  • the operation of the panel 1-2 is carried out under the action of the jack 8 whose head 9 is articulated to the element 1 by an axis 10.
  • FIGS. 2 and 3 show an example of execution of a locking in the closed position provided by a means of displacement of the foot of the jack relative to the support structure integral with the coaming, this means of displacement consisting essentially in cooperation a hinge pin and an elongated hole crossed by the pin.
  • the jack base carries a hinge pin 11 guided in horizontally elongated holes 12 of a support member 13 secured to the coaming 4 so that this jack foot can undergo a small horizontal movement to act on the heel of a locking hook 14 movable about a horizontal axis 15.
  • the body and the foot of the jack are in their left position shown in FIG. 2 by allowing the heel of the hook 14 to advance to the left and consequently the raising of the hook spout 16 at a lateral stop 17 of the panel element 1, the hook being returned to this locking position by any suitable means (not shown).
  • Fig. 4 shows a means of displacement of the foot of the jack 8 equivalent to that of FIGS. 2 and 3 and constituted by a link 18 pivoting about a median axis 19 on a fixed support support 20 and articulated by one end at the foot of the jack around an axis 21 while the opposite end of the link 18 pivots in front of a stop 22 of the panel element 1.
  • the panel element 1 In the locked closed position shown, the panel element 1 cannot move to the left because the stop 22 is stopped by the link 18 whose position is established to guarantee the irreversibility of the pivoting of the rod which is almost horizontal in the locked position.
  • the foot of the actuating cylinder 8 tends to move to the right by rotating the rod 18 anti-clockwise, the movement of which can start thanks to an orientation suitable cylinder in locked locked position, the angle between the axis of the cylinder and the longitudinal axis of the rod being greater than the angle of this axis of rod with the horizontal.
  • the link can be moved from its locked position by the action of the jack but not by the action of the panel, which ensures the desired irreversibility.
  • the head of an actuating cylinder 23 is coupled to a pivoting panel 24 by means of a small lever 25 which carries a locking angle 26 whose end 27 is placed in the closed position behind a fixed stop 28.
  • the pivoting of the lever 26 releases the end 27 of the stop 28 so that the extension of the jack 23 allows the initial small horizontal movement of the panel and its front latch the pivoting of this panel around the fixed axis 29 which passes through a horizontally elongated opening in the end of the panel actuated by the jack 23.
  • the displacement means provided according to the invention between one end of the actuator and the associated structure, for example the panel or the element of the panel coupled to the actuating actuator, may be constituted by a toggle as shown in FIGS. 7 and 8 on which the actuating cylinder has been indicated at 30.
  • the head 31 of this cylinder acts on the axis 32 of the toggle joint composed of two arms 33-34, the ends 35-36 of which are articulated respectively the panel element 37 and a link 38 pivoting around the fixed axis 39.
  • FIG. 7 shows the position of the ge unlocked noodle before the end of the closure or after the start of the opening while fig. 8 shows the locking position, the panel element passing from one of the two positions to the other by a small horizontal movement.
  • Fig. 9 shows an example of locking in. open position actuated by the angle iron which has been shown in FIG. 6 and the end of which can act on a bolt 40 pivoting on the panel element around an axis 41 to hang in the fully open position on a hook 42 carried by a vertical wall at the end of the 'coaming.
  • the pivoting of the angle iron has the effect of lifting the latch by releasing it from the hook while the opposite effect occurs at the end of opening.
  • Fig. 10 schematically shows the locking of an articulated panel composed of two elements 43-44, the figure of which shows the lower ends, the panel being shown in the open position.
  • the. foot 50 of the actuating cylinder 45 is ovalized so that qa'au: start of the closing command it rises due to the traction exerted on the head of the cylinder and this lifting allows the body of the cylinder to raise the hook 46 articulated on the fixed axis 37 so that the spout 48 of this hook emerges from the axis 49 previously locked.
  • actuating cylinder whose rod 52 is coupled to a part 53 with three axes 54, 55, 56 for the connection of this part 53 respectively to the rod 52, to the rod 57 pivoting on the fixed axis 58 and to the panel element 59 actuated by the jack 51.
  • a link 60 is also articulated on the fixed axis 58 and on an axis 61 integral with the panel element 59.
  • the axis 61 continues to be pushed to the left, consequently pivoting around the fixed axis 58 to the final open position shown in FIG. 13 in which the axes 54, 56, 61 on the one hand and 58, 55, .56 on the other hand are practically in alignment, which ensures locking on opening while unlocking at the start of closing results from 'a start of recoil of the cylinder rod 52 which causes the folding of the. knee pads 58, 55, 56.
  • the head of the actuating cylinder 51 that is to say its rod 52, is articulated on a part 53 which also carries the axes of two knee pads 55, 56 respectively carrying out locking in the closed position and in the open position.
