Title: Locking element and locking system for a ship's door, ship's window or hatch.

The invention relates to a locking element for locking the door, window or hatch, relative to a boundary, such as a frame, in a mounting condition of the element attached to a ship door, ship window or hatch, with respect to which the door, window or hatch is hinged. More in particular, the invention relates to a locking element for a weather and / or watertight ship door, weather and / or watertight ship window or weather and / or watertight ship hatch. The invention furthermore relates to a locking system for a weather and / or watertight ship door, weather and / or watertight ship window or weather and / or watertight ship hatch.

It is noted that for the sake of brevity the terms "ship's door" or "door" are often used in this text. In those cases, however, it is to be understood that those terms also include a ship's window or a ship's hatch. It is further noted that in this text the terms “(ship's) door”, “(ship's) window” or “(ship's) hatch” mean doors, windows or hatches of various types of vessels and other maritime objects, including for example offshore installations to become.

Known such elements that are used in known such systems are so-called (door) clamps, also referred to as (door) clips, which are attached near the edge of a door on that side of the door that faces away from the direction to which the door open. Such a known clamp comprises an assembly of a lever extending in one direction and a locking plate extending in another direction, the lever and the locking plate being immobile relative to each other. Said assembly of lever 2 and locking plate is rotatable about an axis of rotation, the position of which is fixed relative to the door. By rotating the lever about the axis of rotation, the locking plate can be rotated from an unlocked position into a locked position, and vice versa. In the locking position, the locking plate clamps against a portion of a boundary with respect to which the door is hinged.

It is also known to use a plurality of such known door clamps in a single locking system for a door, in which system the respective levers of the individual door clamps are mutually connected by means of a rod system such that a user can simultaneously access all the door clamps of the door. operate by means of a single operating handle connected to the rod assembly.

A drawback of the known door mists and the locking systems based thereon is that the system is not very compact. For example, the clamps require a relatively large swivel range of their levers and locking plates, which swivel range projects both on the door surface and on the door boundary. The rod systems that are connected to the levers of the clamps are also not very compact and, moreover, complex.

Furthermore, the clamps suffer from operating forces exerted thereon, which forces are not always directed so favorably, which does not improve the service life of the crank mechanism of the clamps. Replacing parts, such as the clamps, of these known locking systems during maintenance is not always that simple, inter alia because of hinged connections between clamp levers and rod systems. Furthermore, it is quite common for users to suffer (serious) injury to the locking plates of the clamps that rotate strongly in the locking position.

It is an object of the invention to at least provide an alternative locking solution for (weather and / or watertight) ship doors, which solution offers improvements with regard to aspects such as compactness and / or simplicity and / or maintenance and / or safety.

For this purpose, a locking element according to claim 1 is provided according to the invention. Specific embodiments of the invention are laid down in the dependent claims.

According to the invention, therefore, a locking element is provided for locking the door, window or hatch, in a fastening position of the element attached to a ship's door, ship's window or hatch, with respect to a boundary with respect to which the door, the window or the hatch is hinged, which locking element comprises a body and a locking bolt, which body comprises at least one bolt passage for receiving the bolt therein such that the bolt therein can be moved back and forth in its axial bolt direction between at least one locking position and at least one unlocking position, which bolt is provided with rod guiding means for receiving a rod therein such that the rod therein can be moved back and forth in its axial rod direction while the axial rod direction is perpendicular to or otherwise intersecting with the axial bolting direction, and wherein the lich aam and the bolt are arranged such that the rod, if it is received in the rod guiding means in said manner and when it is moved with at least one movement component in the axial firing direction, causes the bolt to move in the axial firing direction for switching between said at least one locking position and said at least one unlocking position of the bolt.

The body and the bolt can each be made of various materials, such as for example a metal or metal alloy, for example stainless steel.

Such a locking element offers compactness, not only because the body and the bolt are compact, but also because of the relatively only small (reciprocating) sliding range of the locking bolt in the axial bolt direction. In this case, not only the sliding range of the bolt projected onto the door surface, but also the sliding range of the bolt projected onto the door boundary is compact. Furthermore, operating the movement of the bolt is simple because this is simply effected by the rod moving with a movement component in the axial bolt direction. Because the rod is slidable with respect to the rod guiding means, no complex fixations are present between the bolt and the rod. Furthermore, the reciprocating bolt offers a lower risk of injury than a rotating locking plate of a clamp. In the locking element, the bolt and the rod perform only relative sliding movements, as a result of which the locking element in principle requires no lubrication and is therefore maintenance-free in that sense.

The absence of relatively vulnerable turning mechanisms makes the locking element robust and extremely durable.

Preferably, the locking element further comprises at least one bolt bearing element which in operation is at least partially received in at least a part of the at least one bolt passage for bearing said reciprocating movement of the bolt in the at least one bolt passage. If the body and the bolt are, for example, made of metal, the bolt bearing element can for instance be a plastic casing for the bolt fixed in the bolt passage, in which casing the bolt can move back and forth.

Preferably, the locking element further comprises a rod bearing element which, during operation, is at least partially received in at least a part of the rod guide means for bearing said rod movement back and forth in the rod guide means. If the rod guiding means and the rod are, for example, of metal, the rod bearing element can for instance be a plastic casing placed in the rod guiding means for the rod, in which casing the rod can move back and forth. In relation to the transfer forces occurring between rod and bolt, it is advantageous if the rod bearing element is made of, for example, a fiber-reinforced plastic.

It is noted that if the bolt bearing element and / or the rod bearing element are made of plastic and could be lost in the event of a fire, this loss has no influence on the primary operation of the locking element. That is, the loss of these elements maintains a locked position or unlocked position of the bolt once occupied and it remains possible to switch between these positions.

Various types of rod guiding means can be used at the bolt. For example, these can be local bulges of the lap. In an advantageous embodiment, the rod guide means 15 are formed by a recess in the bolt. Such a recess is easy to manufacture and contributes to the compactness of the locking element.

The bolt preferably comprises at its one end a chamfer running in the axial firing direction for engaging therewith in the fastening position in the at least one locking position relative to the boundary with respect to which the door, the window or the hatch is hinged. Such a chamfer promotes an advantageous clamping action of the bolt relative to said boundary. Also, for example, special counter elements for the bolt end can be attached to the boundary, which counter elements also have a chamfer that is adapted to the chamfer of the bolt. Such counter elements are in principle interchangeable with other such counter elements, or can for instance be adjustable in shape or orientation so that, for example, the bevel angle, height and the like of the counter element can be varied.

In an advantageous embodiment the body of the locking element comprises a first part and a second part, wherein the first part is adapted to be directly attached to the door, the window or the hatch, and wherein the second part is arranged so as to be detachable , such as for instance by screwing, to be attached to the first part, which after detaching the second part is at least the bolt removable relative to the first part. Such an embodiment offers, for example, the advantages that the locking element can be easily mounted and that parts of a once mounted locking element can be easily mounted and disassembled. In such an embodiment, the first part is preferably adapted to be releasably attached to the door, window or hatch, such as for example by means of welding. This further facilitates the ease of assembly and disassembly, since the first part after the first assembly in principle never has to be removed from the door.

The invention is also embodied in a locking system 20 comprising at least one locking element according to the invention, at least one said rod, and manually or motor-movable operating means for moving the at least one rod with at least said movement component in the axial shot direction in operation. It appears from the above that in operation the freedom of movement of the at least one rod relative to the door is limited by the rod guide means. A locking system according to the invention preferably comprises additional restriction means for additionally limiting the freedom of movement of the at least one rod relative to the door, the window or the hatch during operation. With the aid of these additional restriction means it is possible to prevent the operating means from moving the at least one rod in an undesired direction and it can be regulated that the operating means move the at least one rod in a desired direction.

Preferably, the additional restriction means comprise at least one pivotable element, which pivotal element is pivotally connected to the door, window or hatch at a first location of the pivotal element and, in operation, also to another, second location of the pivotal element element is hingedly connected to the at least one rod. Such a pivotal element limits the freedom of movement of the rod such that the position of the rod connected to said second location of the pivotable element can only move along a circular arc path whose pivot center is formed by said first location where the pivotal element is pivotally connected is with the door. Such a circular arc path is particularly suitable for regulating movements of the rod with movement components in the axial rod direction and in the axial firing direction.

The operating means preferably comprise a manually operable handle which is pivotally connected to the door, the window or the hatch during operation of the handle and which is also pivotally connected to the at least one at another location of the handle during operation. Rod. Such a pivotal element limits the freedom of movement of the rod such that the location of the rod connected to said other location of the handle can only move along a circular arc path whose pivot center is formed by said one location where the handle is pivotally connected to the door. Such a circular arc path is particularly suitable for regulating movements of the rod with movement components in the axial rod direction and in the axial firing direction.

In an advantageous embodiment, the locking system comprises at least two such locking elements, wherein, for at least one of the at least one rod, that one rod, in operation in the said manner, is accommodated in separate rod guide means of associated individual of the at least two locking elements. Thus, a single rod can operate several separate locking elements simultaneously.

In an advantageous embodiment, the locking system comprises at least two such locking elements 10 and at least two such rods, wherein, for at least one pair of the at least two rods, the two separate rods of said pair in operation in said manner in separate rod guide means of associated individual of the at least two locking elements are included, and in operation the two separate rods are mutually coupled by a hinged element as mentioned above, which hinged element is pivotally connected to the one of the two separate rods in operation at the second location of the hinged element and said pivotal element in operation at a third location, other than said first location and said second location, of the pivotal element is pivotally connected to the other of the two separate rods. Thus, two rods can be mutually coupled by such a pivotal element, while said pivotal element thereby restricting the freedom of movement of each of the two rods along a separate circular arc path whose pivot center is formed by said first location where the pivotal element is pivotally connected to the door . Such circular arc paths are particularly suitable for regulating coupled movements of each of the two rods with movement components in the respective axial rod and bolt directions associated with the rods.
