Description

SHOCK—SECURE DOOR OR HATCH ARRANGEMENT ON MARINE SHIPS 1. FIELD OF THE INVENTION The invention relates to means for a shock-secure or shock-safe door or hatch arrangement on marine ships. 2. OUND OF THE INVENTION 1O It is known to use shock~secure doors and hatches on ships. In such arrangements, a door leaf is pivotally supported via hinges in a closed position in a doorway frame. Seals are located between the door leaf and the doorway frame. Corresponding latching elements that engage into one another and are adjustable via a handle for fixing the door leaf in the doorway frame in a latching or g position.

In such arrangements on marine ships, the difficulty exists of transmitting the forces of shock events into the doonNay frame in order to t an unintended springing-open of the door leaf when in closed position.

From patent document DE 10 2006 041 141 BS it is known to carry out a latching or g between door leaf and doorway frame by way of slidable rod linkage elements ating with a plurality of corresponding latching tongues or strap plates distributed over the ter of the door/hatch, and to form a closed perimeter~encircling operating ring via ball elements in corner areas. In this regard, problems arise in the operation of the latch/lock through additional remote—controllable operating elements, and there is a danger that rod linkages are no longer manipulable in a correct, orderly manner after shock loading.

It would be advantageous to provide a force—withstanding stability door that is subject to strong shock loading, with means which ensure an unintended ing-open is d while also allowing remote-control door opening and closing. 3. SUMMARY OF THE ION The invention provides an arrangement for shock-secure installation of a door or hatch on marine ships, wherein a door leaf is pivotably supported via hinges in a doorway frame and is receivable therein with osition of seals in a closed position, the door leaf and the doorway frame having corresponding ng elements that engage into one another and that are operable via a handle for fixing the door leaf in the doorway frame in a latching or locking position, characterized in that the doorway frame, on two oppositely located longitudinai sides, is ed with continuous latching bars, as part of said corresponding ng elements, which are receivable in corresponding grooves, which provide the other part of the corresponding latching elements, of a door leaf frame of the door leaf, wherein the latching bar located on the side of the door leaf pivotably connected with the doorway frame is stationary and is shaped for engaging into the groove of the door leaf frame during a closing motion of the door leaf, and wherein the latching bar located at the opposite side of the door leaf is guided at and able in the doorway frame in a manner whereby it is insertable via adjustment elements into the associated groove of the door leaf frame in the closed position of the door leaf.

With this arrangement, an allocation of the individual elements with relatively small play is possible, and a continuous or through-going uptake of arising shock loads is ensured without impairments.

A simple actuation or control is provided in that the adjustment elements for the latching bar can advantageously be in form of pneumatic cylinders and/or pivotable operating levers.

Furthermore, for security and avoiding a g displacement in the closed position, it is preferred that the able latching bar comprises a parallel arranged securing or g rod in the doorway frame, which is arranged to be adjustable vertically or perpendicularly to the latching bar via an allocated operating lever. In this regard the securing or locking rod may advantageously have, or integrally comprise over a section thereof, a toothed gear rack into which a corresponding tooth or gear element of the pivot axis of the operating lever engages for performing the adjustment.

A small play between door leaf and y frame can be advantageously achieved by forming or providing the sectional profiles of the door leaf frame ted to the doorway frame with a sloping taper in the area of the ted ng bars for guidance into the groove.

Further, it is ageous if the pivotable operating levers are devised to act on the latching bar via bolts via an over~dead~center bearing or over-center toggle in the latching position.

As an additional ty or safety, means the outwardly located surfaces of the door leaf and doorway frame may comprise ponding fixture elements as shock limiters that brace against one another in the closed position of the leaf within the door frame.

Further preferred features will become apparent from the following description of an embodiment of the invention which is schematically illustrated in the accompanying drawing: 4.

. DESCRIPTION OF PREFERRED EMBODIMENT [n the marine ship hatch/door latching arrangement illustrated in the figures, a door leaf 1 is connected pivotably via hinges 2 to a doorway frame 5, for closing an g 3 in a ad 4 at which the doorway frame is fixed.

According to Fig2, a pneumatic adjusting or actuating cylinder, shown at the top of frame 5, is allocated to the door leaf 1 for pivoting it within frame 5, in order to carry out remote controlled opening and closing via an electro-pneumatic control arrangement (not shown).

The y frame 5, at the side where the hinges 2 are located and where it is connected with the door leaf 1, has a stationary latching bar or rail 6 for engagement or insertion in a corresponding groove 7 of a door leaf frame 8 which provides opposite udinal edges at the door leaf 1. The nal e of the door leaf frame 8 ses a sloping taper for guiding the latching bar 6 into the groove 7. An overlapping al area of the door leaf frame 8 has a seal 9 that lies in contact on the doorway frame 5 in the closed position of the door leaf 1. The stationary latching bar 6 is secured to the doorway frame 5 in adjustable manner.

On the side located opposite hinges 2, the doorway frame 5 has a latching bar 10 that is received in guided and adjustable manner at the doorway frame 5.

Latching bar 10 is insertable into a corresponding groove 13 of the door leaf frame 8 for latching or looking, and is held in this latching or locking position via a pneumatic cylinder 11 and pivotably arranged operating levers 12. To achieve this functionality, the pneumatic ers 11 and the operating levers 12 engage the latching bar 10 via bolts 14, whereby the pivoted operating levers 12 are held in the looking or latching on via an over-center toggle or over-dead-center—point bearing.

As best seen in Fig7, a parallel securing or locking rod 17 is arranged parallel to the adjustable latching bar 10 in the doon/vay frame 5. The securing or locking rod 17, after latching or locking the door leaf 1 in its closed or locked position, ts sliding displacement of the latching bar 10 in the area of guide 15. The vertical sliding displacement is adjustable via an operating lever 16, whereby securing or g rod 17 is heretofore provided with or formed as a toothed gear rack 18 in the engagement area of the operating lever 16. A corresponding tooth or gear element at the pivot axis of the operating lever 16 s into the toothed gear rack 18 for performing the adjustment.

Additionally, fixture elements 20 and 21 are ed on the outwardly located surfaces of door leaf 1 and doorway frame 5, respectively, and these fixture 1O elements 20 and 21 abut or contact against one another in the closed position of the door leaf, within the doorway frame opening 3, and serve as shock limiters.
