Description

Title of the invention: Locking device for a deck hatch or opening panel in a ship's window Scope of the invention

[0001] The field of the invention is that of nautical activities.

[0002] More specifically, the invention relates to a locking device for a ship deck hatch.

[0003] The invention finds in particular an application for locking hinged or sliding type openings made of transparent, translucent, tinted or solid opaque materials. Previous art

[0004] To lock the opening of a deck hatch of a boat, it is known to implement a bolt on the opening of the deck hatch, which is operated by means of a handle and engages in a strike plate fixed on the frame of the deck hatch.

[0005] Locking mechanisms for deck hatch openings are known, in which the handle is mounted pivotally relative to the hatch. In order to lock the handle in the position where the bolt it controls is engaged in the strike plate to prevent a thief from entering the cabin, it has been proposed to implement a push-button locking mechanism that locks the position of the handle and the bolt relative to the hatch.

[0006] For obvious safety reasons, however, it is imperative that a navigator be able to ensure that the openings of the deck hatches are locked without their locking handles being themselves locked before starting navigation.

[0007] However, one disadvantage of handles equipped with a push-button lock is that you have to get close to the button to check if it is locking the handle, which takes time and can be tricky when the passenger compartment is cluttered. Objectives of the invention

[0008] The invention therefore aims in particular to overcome the disadvantages of the prior art mentioned above.

[0009] More specifically, the invention aims to provide a reliable locking technique for a deck hatch.

[0010] An objective of the invention is also to provide such a technique that allows the user to ensure by a simple visual check that the handle allowing to ver-

[0019] rusting the opening is itself unlocked. Another objective of the invention is to provide a locking technique for a deck hatch opening that is simple to implement. Another objective of the invention is to provide such a technique that has a reduced cost price. Description of the invention These objectives, as well as others which will appear subsequently, are achieved using a locking device for a deck hatch or opening panel in a ship's window comprising: - a base suitable for being fixed to said opening; - a body mounted pivoting relative to said base, said body having a protruding element forming a bolt adapted to cooperate with a strike plate to ensure the locking of said opening; - a handle attached to the said body. In the context of this invention, the term "deck hatch" refers to a watertight assembly mounted flat or at a slight angle on the deck of a ship, consisting of a frame or structure, also called a fixed part, and a hinged or sliding opening panel mounted on hinges or jacks. The term "window opening panel" further refers to an assembly consisting of a tilting or sliding opening panel, glazed, translucent, or transparent, mounted in a frame that fits into a larger pane of glass positioned vertically or at an angle. We finally hear the terms bolt and strike plate in their general sense, namely that the bolt is a movable part intended to engage in a strike plate fixed to the frame to ensure the locking of the opening. According to the invention, said handle has a locking finger of said handle projecting towards said base and in that said handle is mounted pivotally relative to said body along an axis substantially perpendicular to the pivot axis of said body relative to said base between at least two positions: - a locking position of said handle in which the handle extends substantially perpendicularly to the pivot axis of said body and said finger is inserted into a housing formed in said base; - at least one unlocked position of said handle in which said handle is pivoted so as to move away from said base and said finger is out of said housing. Thus, in a novel and particularly ingenious way, the invention proposes to implement a pivoting handle that simply needs to be lifted to activate the bolt. and which locks simply by lowering it so that its locking pin engages in the base of the device attached to the door, or vice versa. Therefore, simply observing the handle's position (whether it's lowered or raised) is enough to determine if the handle is locked or not.

[0020] In a particular embodiment of the invention, said housing forms a notch in said base.

[0021] In other embodiments of the invention, it may be provided that the housing takes any other suitable known form.

[0022] According to a particular aspect of the invention, in said unlocked position, said handle forms an angle between 10 and 60° with said pivot axis of the body.

[0023] This limits the lifting of the handle.

[0024] Preferably, said handle has a flank extending substantially in the direction of the pivot axis of said body and configured so as to be in contact with said body in said unlocked position.

[0025] This prevents the handle axis from being damaged when pushing on the handle to rotate the body.

[0026] Advantageously, said body has means for securing a removable handle intended to open the opening from the outside.

[0027] The hatch can thus be opened or closed from the outside. It should be noted that this is particularly useful in the event of the ship's hull capsizing, to free a person trapped inside the cabin.

[0028] Advantageously, said means for securing a removable handle have a contour cavity in the shape of an eight-pointed star configured to accommodate a star-shaped imprint of a winch key.

[0029] The opening can thus be opened or closed from the outside using a simple winch key.

[0030] In a particular embodiment of the invention, said external removable handle has at least one fixing clip on said means for securing a removable handle.

[0031] In a particular embodiment of the invention, said locking handle has a projecting stop element configured so as to be able to come into contact with said body, said projecting stop element and said locking finger projecting from the handle respectively on one side and the other side of the pivot axis of the locking handle.

[0032] The protruding element forming a stop thus makes it possible to limit the tilting amplitude of the handle.

[0033] According to a particular aspect of the invention, said bolt has a fork shape intended to house a tongue.

[0034] In a variant of this embodiment of the invention, the bolt has a tongue-like shape intended to fit into a forked strike plate.

[0035] In a particular embodiment of the invention, said body has a radially projecting stop element that fits into an arc-shaped recess formed in said base.

[0036] This limits the amplitude of angular rotation of the body.

[0037] According to an advantageous embodiment of the invention, said handle has pictograms to indicate in what position to place the handle.

[0038] According to a particular aspect of the invention, said pivot axis of the handle and said pivot axis of the body are not intersecting. List of figures

[0046] [Fig.7] is a perspective view of the left locking device shown in reference to [Fig.1] from which the removable handle has been removed;

[0047] [Fig.8] is a perspective view of the removable handle of the locking device left rusting shown in reference to [Fig.1], shown alone. Detailed description of the invention

[0048] Figure 1 illustrates a deck panel 10 of a pleasure boat, seen from inside the cabin, consisting of a glazed opening 11 with a substantially square outline mounted to tilt relative to a frame forming a fixed part 12. This deck panel is equipped with two locking devices for the opening 13 and 14 mounted respectively near the lower left edge and the lower right edge of the opening 11.

[0049] In this particular embodiment of the invention, each locking device 13 or 14 has a bolt 13i or 14i that engages with a seal forming a strike plate 15 fixed to the frame 12.

[0050] Figures 2 and 3 show the locking device 13 alone, respectively when its handle 23 is locked or unlocked.

[0051] This locking device 13 comprises a body 21 in two parts screwed together, each part projecting on either side of a base 22. This body 21 is mounted to pivot about the axis 26 relative to the base 22 and is operated from inside the boat's cabin by means of the handle 23 attached to the upper part of this body 21. The fork-shaped bolt 13i is formed in the upper part of the body 21.

[0052] The base 22 is fixed to the opening 13 (not shown in figures 2 and 3 for the sake of readability) by its substantially rectangular base 22i which fits into the opening 13.

[0053] A removable handle 24 is attached to the lower part of the body 21, under the base 22. This handle 24 allows the body 21 to be operated from outside the passenger compartment.

[0054] As can be seen in [Fig.4], which is an exploded view of the assembly of the handle 23 with the upper part of the body 21, the handle 23 is mounted to pivot about the axis 41 relative to the body 21. It should be noted that the axis 41 represented by the dashed lines 27 in Figures 2 and 3 extends perpendicularly to the pivot axis of the body 21 and is mounted on the bearing surfaces 42.

[0055] The handle 23 also has a protruding finger 23i pointing towards the base 22, which is inserted into the notch 222 formed in the base 22 when the handle 23 is lowered (see [Fig. 3]). In this position, shown in [Fig. 3], the handle is locked. To unlock the handle 23, simply rotate the handle 23 away from the base 21 until the finger 231 is out of the notch 222. The body 21 can then be rotated by pushing on the handle perpendicular to the pivot axis 26 of the body 21. It should be noted that to ensure a suitable contact surface between the handle 23 and the body 21, the handle 23 has a flank 44 extending towards the base 22 in contact with the portion of the upper part of the body 21 from which the bolt 13p extends. It should also be noted that a recess 43 is provided in the upper part of the body 21 to allow the passage of the finger 23b.

[0056] In order to limit the pivoting of the handle 23, a second projecting part 45 is provided under the handle 23, on its part extending relative to the axis 41 on the side opposite to the part of the handle on which the finger 231 is formed

[0057] Pictograms 25 are also represented on the distal end of the handle 23 to indicate to a user how to lock and unlock it.

[0058] It should be noted that the pivoting of the body 21 relative to the base 22 is limited in amplitude. The body 21 has a protruding lug 51 (see [Fig. 5]) which fits into a recess 61 in the base (see [Fig. 6]) shaped like an arc. This lug will then come to rest against one end of the recess when the handle is gradually rotated around the axis 26 in one direction or the other, thus preventing the body 21 from pivoting beyond this limit position.

[0059] It should also be noted in [Fig. 7], where the locking device 13 is shown without the removable handle 24, that the lower part 71 of the body 21 has a cavity 72 with an eight-pointed star-shaped contour adapted to accommodate a star-shaped imprint of a winch key. It can be seen in [Fig. 8], where the handle 24 is shown alone, that it has a clip 81 shaped to allow the removable handle 24 to be clipped into the cavity 72.
