Description

Glazed window for ship equipped with an opening closed using a tilting glass panel.

Field of invention

The field of the invention is that of portholes and windows for ships.

More specifically, the invention relates to a device for closing off a bay formed in a substantially vertical outer wall of a ship comprising a fixed glazed panel and a glazed panel mounted tilting with respect to said fixed glazed panel, which can close off or release a substantially trapezoidal opening formed in said fixed panel.

The invention finds particular application in pleasure boating.

Prior art

It is known to have opening portholes, which are small watertight windows of generally rounded shape, to provide light and allow fresh air to enter the hull of a ship. These opening portholes open, for example, by tilting to the side or upwards.

To ensure the tightness of a porthole opening once closed, a seal mounted on the contour of the porthole is compressed against the frame, which is most often made of aluminium, bronze or stainless steel, by screwing a plurality clamping elements, and generally 4 to 6 clamping elements, or more, depending on the size of the window.

A disadvantage of this porthole technique is that a porthole has a metal frame that limits its glass surface.

Another disadvantage of this porthole technique is that a large number of clamping elements must be provided, and generally at least 3 to 4 clamping screws, to ensure adequate sealing.

Furthermore, these portholes are generally small in size.

In order to increase the glazed surface of pleasure boats while improving their aesthetics, it has been proposed to integrate glazed panels into the hull, which are flush with it from the outside.

To ventilate the interior of these ships, a known technique consists in providing an opening in the fixed glazed panel which can be released or on the contrary closed by acting on the position of a sliding or tilting glazed panel, mounted without a frame.

In the case of a sliding glazed panel, it is generally mounted on rails glued to the interior surface of the fixed glazed panel or which extend beyond the fixed panel and are fixed to elements of the shell made of aluminium, wood or composite material.

When the glazed panel intended to close the opening is mounted tilting, the latter is articulated with respect to the fixed panel around one or more hinges and the tightness of the opening is ensured, according to known techniques, at the using 3 or 4 clamping handles, or more, which allow to compress a seal over its entire length between the tilting glass panel and the fixed panel of the window.

A drawback of these known techniques for windows equipped with an internal tilting glazed panel is that it is necessary to provide numerous clamping handles, which makes it tedious to lock and release the tilting glazed panel and reduces the useful translucent surface of the window. .

Objectives of the invention

The object of the invention is therefore in particular to overcome the drawbacks of the prior art mentioned above.

More specifically, the aim of the invention is to provide a technique for closing off a window formed in a substantially vertical outer wall of a ship which is easy to use in terms of handling and which is reliable in terms of sealing.

An object of the invention is also to provide such a technique which is simple to implement.

Another object of the invention is to provide such a technique which is of reduced cost.

Another object of the invention is to provide such a technique for closing a bay formed in a substantially vertical outer wall of a ship in which the fixed glazed panel and the tilting mounted glazed panel are flush, seen from the outside.

These objectives, as well as others which will appear subsequently, are achieved with the aid of a device for closing off a bay formed in a substantially vertical outer wall of a ship comprising a fixed glazed panel and a glazed panel mounted tilting relative to said fixed glazed panel, able to close or release a substantially trapezoidal opening made in said fixed panel,

said device comprising a seal mounted on the edge of said opening,

said tilting panel being secured to said fixed glazed panel by means of two hinges, said hinges being fixed to said tilting panel each substantially at one end of the upper edge of said tilting panel and to said fixed panel on the upper edge of said opening,

said device comprising a first and a second handle for locking said tilting panel in the position for closing said opening, each mounted close to a lower corner of said opening.

According to the invention, the value of the product of the thickness of said tilting glazed panel with the Young's modulus of said tilting glazed panel is greater by at least 15% than that of the product of the thickness of said fixed panel with the modulus of 'Young said fixed panel.

The invention thus proposes, in a novel way, to provide a tilting glazed panel whose thickness is at least 15% greater than the product of the thickness of the fixed glazed panel with the ratio between the Young's modulus of the fixed panel and the Young module of the tilting glazed panel, in order to ensure proper sealing of the opening by locking only two clamping handles. The inventors have in fact observed that a thicker tilting glazed panel makes it possible to maintain suitable sealing when the glazed panels deform under the action of a thrust, which can reach 0.14 kg/cm ² , exerted by waves hitting the panels.

It should be noted that within the scope of the invention, the locking handles can be mounted along the lower edge of the opening or along a vertical side edge of the opening.

It will also be noted that in the context of the invention, the term “glazed panel” must be understood in its most general sense and corresponds to a translucent panel which can be made of glass, of material, of translucent thermoplastic material, or in any other suitable translucent material.

Finally, it will be noted that by “substantially at one end of the upper edge of said tilting panel”, it is meant that the hinges are fixed at a distance from the upper corners of the tilting panel less than 25% of the length of the upper edge of the tilting glazed panel.

In an advantageous embodiment of the invention, the device as described above comprises two and only two hinges.

In an advantageous embodiment of the invention, the device as described above comprises two and only two locking handles of said tilting panel.

In a particular embodiment of the invention, the value of the product of the thickness of said tilting glazed panel with the Young's modulus of said tilting glazed panel is greater by 20% to 40% than that of the product of the thickness of said fixed panel with the Young's modulus of said fixed panel.

In another particular embodiment of the invention, the value of the product of the thickness of said tilting glazed panel with the Young's modulus of said tilting glazed panel is greater by 40% to 300% than that of the product of the thickness of said fixed panel with the Young's modulus of said fixed glazed panel.

In an advantageous embodiment of the invention, said handles are mounted at a distance from one end of the lower longitudinal edge of said tilting panel less than the greater of the following two values:

- 15% of the length of said lower longitudinal edge of said tilting panel;

- 70 millimeters.

Advantageously, the thickness of said fixed glazed panel is at least equal to 8 millimeters, and preferably is greater than or equal to 10 millimeters.

This limits the deformations of the glazed panels.

In a particular embodiment of the invention, said fixed glazed panel and said tilting glazed panel are made of the same material, and preferably polymethyl methacrylate.

According to a particular aspect of the invention, said opening and said tilting panel have a substantially rectangular outline.

According to a particular aspect of the invention, a closure device as described above comprises a third handle mounted on the lower longitudinal edge of said glazed panel tilting between said first handle and said second handle.

In a particular embodiment of the invention, a closing device as described above is configured to close a bay formed in the hull of a ship.

In a variant of this particular embodiment of the invention, it can be envisaged that a closure device as described above is configured to be mounted in a vertical wall at the level of the deck of a ship.

Preferably, in the closed position, the face of the fixed glazed panel facing the outside of said ship and the face of said tilting panel facing the outside of said ship are substantially flush.

Thus, an aesthetic appearance is conferred on the closure device, seen from the outside.

Detailed description of the invention

There is illustrated in Figures 1A and 1B a first embodiment of a device 10 for closing a bay formed in the hull of a pleasure boat according to the invention, in front views of the device 10, viewed from inside and outside respectively.

This device 10 comprises a fixed glazed panel 11 pierced in its center with a rectangular opening 12 with rounded corners and a glazed panel 13 tilting upwards around an axis 16, represented in a position of closure of the opening 12 in Figures 1A and 1B.

In this particular embodiment of the invention, the fixed glazed panel 11 and the tilting glazed panel 13 are made of PMMA (acronym for polymethyl methacrylate in English) and are tinted.

On the outer face of the device 10 (see FIG. 1B), two strips 18 intended to form covers are mounted on the fixed glazed panel 11.

There is shown in Figure 2 the device 10, in a front view, seen from the inside, after removing the metal profile 15 which forms a cover covering the upper part of the tilting glazed panel 13 and the upper edge of the opening 12. In this figure 2, it can be seen that the tilting glazed panel 13 is articulated in rotation about the axis 16 with respect to the fixed glazed panel 11 by two hinges 21 known per se, mounted near the upper corners of the opening 12. These hinges 21 each agree along the upper edge of the opening 12 over approximately 13% of its length.

On the inside face of the device (see FIG. 1A), two locking handles 14 movable around vertical axes 17 make it possible to maintain the tilting panel 13 in the closed position, when they are folded against the inside face of the tilting glazed panel 13.

These handles 14 are mounted near the ends of the lower longitudinal edge of the tilting panel 13. It can be seen in Figures 3 and 4, which are respectively a partial cross-sectional view of the closure device 10 and a bottom view of a handle 14, that these handles 14 each have a through groove 31 in an arc of circle which encloses a finger 32 projecting upwards formed on the surface of an anchoring piece 33 fixed to the fixed panel 11, in the position d closure of the opening. This groove 31 is offset with respect to the axis of rotation 17 of the handles 14 in order to make it possible to pass from a position where the tilting glazed panel 13 is locked to a position where the tilting panel 13 is released and can be tilted upwards. up, by turning the handle 14 a quarter turn.

In this particular embodiment of the invention, each anchor 33 is fixed to the fixed panel 11 at approximately 12% of the length of the lower edge of the opening from a lower corner of the opening 12 .

A seal 34 in EPDM (acronym for ethylene-propylene-diene monomer) with adhesive is bonded in a shoulder 35 formed on the contour of the tilting panel 13. This seal 34 is compressed against the fixed panel 11 in the position closing the opening 12. To ensure uniform and sufficient compression of the seal 34 against the fixed glazed panel 11, provision has been made for the thickness 36 of the tilting glazed panel to be 20% greater than the thickness 37 of the fixed glazed panel 11, in this particular embodiment of the invention.

In Figure 3, it can also be seen that the outer face 38 of the fixed glazed panel 11 and the outer face 30 of the tilting glazed panel 39 are advantageously positioned relative to each other flush, in the position of closing the opening 12.
