  • HINGE MEANS FOR MOVABLE CLOSURE PANELS AND PANELS PROVIDED THEREWITH Filed March 5, 1963 3 Sheets-Sheet 2 II ⁇ I ⁇ /EI ⁇ ITOR Pew ERIK dorvss ON Nov. 30, 1965 Filed March 5, 1963 PER-ERIK JONSSON HINGE MEANS FOR MOVABLE CLOSURE PANELS AND PANELS PROVIDED THEREWITH 5 Sheets-Sheet 5 /l ⁇ I ⁇ /EI ⁇ /TOIQ PER EI JK JONSSON 1 /ATTO !E/5 position.
  • This invention relates essentially to hinge means for pivotally connecting a plurality of elements constituting a movable panel for closing the hatchway of a ships hold or like aperture to the edge of said aperture, or for a panel consisting of two or more panel elements or sections pivotally interconnected, said panel being adapted to be mounted on its small or narrow side on a support disposed laterally with respect to said aperture so as to occupy a substantially vertical position. It has already been proposed to connect the panel or the panel section nearest to said support on each one of the two opposite edges of the hatchway by means of a simple one-piece arm projecting with respect to the panel or panel section and pivoted at a fixed point on said support.
  • This hinge device suffers from certain inconveniences due to the fact that the vertical space occupied by the corresponding links or arms, in the upright or stowed position of the panel is too considerable. These inconveniences are more pronounced when the panel or panel sections are to be operated through hydraulic mechanisms incorporated in said panels or panel sections.
  • the panel or cover section at one end is provided near its outer end edge with a pair of side rollers or wheels running on tracks extending outside of the hatchway from runways on the hatch coaming and also with a pair of endwise projecting spaced arms fitted with follower trunnion pins, the pins engaging guiding slots arranged in upstanding support members outside of the hatch in such a manner that said cover section may swing on its wheels to a vertical position for stowage on said tracks.
  • a drawback of such a design is that the friction incident to the sliding engagement of the pins with the slots tends to resist the powered motion of the cover, resulting in a requirement for increased motive power.
  • This invention is also concerned with hatchway panels or like structures equipped with a hinge device of the type set forth hereinabove.
  • FIGURE 1 illustrates diagrammatically in side elevational view a hatchway panel divided into four sections shown in their hatchway closing position and comprising an end section connected to a hinge device constructed according to this invention
  • FIGURE 2 is a diagrammatic side elevational view showing the same hatchway panel structure with the panel sections stowed at one end of the hatchway;
  • FIGURE 3 is a diagrammatic side elevational view showing on a larger scale the right-hand portion of FIG- URE 1;
  • FIGURE 4 is another side elevational view showing on a larger scale the right-hand portion of FIGURE 2;
  • FIGURE 5 illustrates diagrammatically on a larger scale a plan view of the device of FIGURE 3.
  • FIGURES 6 to 8 inclusive are other diagrammatic views corresponding to FIGURES 3 to 5 but showing another form of embodiment of the device of this inventron.
  • the reference numeral 1 designates the frame or coaming surrounding the hatchway aperture and carrying a flange 2 supporting the panel sections 3, 4, 5 and 6 (which are four in number in the drawings), although this number can be varied to suit requirements shown in the hatchway closing position.
  • the adjacent edges of these panel sections are interconnected through links 14 so that the panel sections may be moved from said closing position in which they are substantially coplanar to a vertical position by moving these sections through a suitable device, not shown, so that they are pushed together from the left, as seen in FIGURE 1, by pivoting simultaneously about their horizontal pivot or hinge pins. In this stowed position they occupy little space in the horizontal direction.
  • rollers or wheels 7 adapted to roll on the coaming flange 2 having an extension 2 on the right-hand side of the frame 1 over a frame or support 8 constituting a track or base for the panel sections.
  • the end of flange or track 2' which is remote from the hatchway frame 1 is provided with a stop member 9.
  • the edge of panel section 6 nearest to the support 8 in the open hatchway position is carried by a pair of wheels 7 and rigidly connected, inside each track extension 2', with an arm 10 extending obliquely downwardly toward the remote end of support 8 so as to form a relatively small angle with the horizontal.
  • this arm 10 is connected through a horizontal pivot pin 11 to one end of a link 12 having its opposed end pivoted by means of a horizontal pin 13 to the remote end of support 8.
  • the arm 10 and link 12 form together an obtuse angle with the vertex directed downwardly.
  • FIGURES 6 to 8 ditfers from the form of embodiment of FIGURES 1 to described hereinabove in that the pivot pin 13 is adapted to slide in a substantially horizontal plane and in a direction at right angles to its axis, said pivot pin being connected to another arm and link system pivoted in turn on said support 8 through a pivot pin held against lateral sliding movement.
  • the support or like structure 8 is provided on both sides with a horizontal slideway 17 extending at right angles to the pin 13 and guiding a slide block 18 or a pair of slide blocks 18, said pin 13 being journalled in said slide block or blocks.
  • the link 12 connected to the pivot pin 13 has an extension in the form of an arm 19 (or is rigidly connected thereto) pivoted in turn by means of a pin 20 on one end of a link 21 having its other end pivoted through a pin 13 on the support 8. This last-named pivot pin 13' is therefore held against lateral movement.
  • the arms of the two-armed lever 12, 19 form together, in the hatchway opening position, an obtuse angle having its angle directed downwardly.
  • pivot pin 13 may also be mounted in a slide block like the pivot pin 13 and connected to a complementary arm and link system pivoted in turn on the support by means of a pivot pin held against lateral motion, and it is assumed that this complementary arm and link system (or a multiple system) constitutes an integral part of this invention. 7*
  • a device in a ship having at least one deck with at least one hatch therein, a coaming surrounding the hatch and having at least two opposite sides, a pair of substantially parallel runways provided on and along said opposite 2.
  • said linkage means comprises a substantially straight rod and said fixed pivot point is substantially on a level with the pivotal connection of said rod with said bracket arm.
  • a device forms the end cover section of an even number of pivotally interconnected cover sections, each cover section carrying at least one pair of side wheels and said cover sections being foldable in close order in an upstanding stowed position on said tracks in which stowed position said cover sections are arranged in pairs, and the adjacent cover sections of two successive pairs being pivotally connected through at least one drag link.
  • said rod comprises a pair of substantially parallel connecting links formed with apertured ends, which connecting links are pivoted at one end through a trunnion pin to said bracket arm and arranged in symmetrical relationship on either side thereof, and pivoted at the opposite end through a pivot pin to said frame.
  • said linkage means comprises at least one two-toggle system having a double-armed lever rotatably fulcrumed intermediate its ends to said frame through a trunnion pin reciprocally movable along a substantially straight path in constraining guide means formed on said frame and extending substantially parallel to said tracks, one lever arm of the double-armed lever being pivoted to said bracket arm, and a link pivotally connected at one end to the other lever arm of the double-armed lever and at its opposite end to said fixed pivot point.
  • a device wherein said trunnion pin of said double-armed lever is carried by at least one sliding block, said sliding block engaging a substantially straight guide slot extending substantially parallel to said tracks, and wherein said fixed pivot point is substantially on a level with the center line of said guide slot, said double-armed lever being bent so that the two lever arms thereof form an obtuse angle the vertex of which is pointing downwards, the lengths of said guide slot and of said link being such that, in the hatch closing position of said cover panel, said other lever arm and said link are substantially aligned in extension of each other parallel to said tracks.
  • cover panel forms the end cover section of an even number of pivotally interconnected cover sections, each cover section carrying at least one pair of side wheels and said cover sections being foldable in close order in an upstanding stowed position on said tracks in which stowed position said cover sections are arranged in separate pairs, and the adjacent cover sections of two successive pairs being pivotally connected through at least one drag link.
  • said doublearmed lever comprises a pair of substantially parallel connecting rods formed with apertured ends and pivoted endwise throught pins to said bracket arm and link respectively in symmetrical relationship on either side thereof, said trunnion pin being supported endwise by two sliding blocks respectively engaging two confronting guide slots arranged in said frame in registering relation.
  • a device having a second twotoggle system similar to the first named two-toggle system, and having a second double-armed lever, pivoted on a constrainedly slidable fulcrum, and a second link hingedly connected to said second double-armed lever, said second two-toggle system being interposed and pivotally connected in series between said first named link and said fixed pivot point.
