PREFERRED EMBODIMENT OF THE INVENTION

With reference to Figure 1, reference numeral 1 indicates, as a whole, a bed base for ship which is particularly suitable to be used inside boats such as cruise ships, military vessels or the like.
The bed base for ship 1 comprises a support frame 2 and a support surface 3 designed to support a mattress (not illustrated). The support frame 2 and the support surface 3 are made of metal material, for example steel or the like. The support surface 3 is integral with the support frame.
According to a preferred embodiment shown in the accompanying figures, the support frame 2 has the shape of a quadrilateral. In the illustrated example, the support frame 2 preferably has an approximately rectangular shape. Furthermore, it is understood that the present invention is not limited to a rectangular support frame 2 but may envisage other shapes such as square, trapezoidal or the like.
According to a preferred exemplifying embodiment shown in Figure 1, the bed base for ship 1 has a reference axis A and comprises a series of preferably rectilinear metal rods or bars 4 with a substantially rectangular section that are arranged transverse to the longitudinal axis A.
According to a preferred exemplifying embodiment shown in Figure 1, the support surface 3 comprises a metal bed base 5 which is fixed perimetrically to the support frame 2, preferably but not necessarily resting on the underlying bars 4.
Preferably, the bars 4 have the two opposite ends fixed at the head, for example by welding, to the support frame 2, preferably to the inner side walls of the two sides of the support frame 2 parallel to the longitudinal axis A, whereas the metal base bed 5 can be fixed perimetrically to the support frame 2, at least on two parallel and opposite sides of the same, for example by welding.
According to a preferred exemplifying embodiment shown in the accompanying figures, the support frame 2 preferably comprises one or more tubular profiles 6 (cranes). The tubular profile(s) 6 extend along a longitudinal axis B and have a quadrangular, preferably rectangular section transverse to the same.
According to a preferred embodiment shown in Figures 1 and 2, the support frame 2 comprises a single tubular profile 6 that preferably has four bends P₁-P₄. Preferably, the four bends P₁-P₄ are approximately right-angled (i.e. 90°) and are shaped so as to have a radius of curvature R₂ at the relative vertices. The four bends P₁-P₄ are made at the respective four points of the tubular profile 6 that are intended to form the corners of the support frame 2.
In other words, the initially rectilinear profile 6 is preferably shaped substantially in the shape of a rectangle and the two opposite end (or head) portions are arranged adjacent to and facing each other. In the illustrated example, the support frame 2 is preferably monolithic and is preferably made from a single tubular profile 6.
The radius of curvature R₂ is preferably comprised between approximately 80 mm (millimetres) and approximately 100 mm, and more conveniently is equal to approximately 90 mm.
In addition, in the preferred embodiment of the invention, an end portion 6a of the tubular profile 6 with a pre-set length ℓ₁ preferably has a narrowing/bottleneck 7.
The length ℓ₁ is preferably comprised between approximately 40 mm and approximately 200 mm, and more conveniently is approximately equal to 70 mm.
More specifically, the end portion 6a is preferably subjected to a deformation process, such as for example a rolling or a pressing, which has the aim to locally reduce the transverse dimensions of the end portion 6a and obtain the narrowing 7 so that it is possible to insert/engage the end portion 6a inside the opposite and facing end portion 6b of the tubular profile 6 and form the support frame 2.
According to a preferred embodiment shown in Figure 2, the tubular profile 6 has a substantially rectangular, hollow cross-section preferably having at least one upper shoulder 8 which, in use, is designed to receive resting the support surface 3, so that the support surface 3 is positioned slightly recessed in and/or substantially flush with the support frame 2.
According to a preferred exemplifying embodiment shown in Figure 2, the tubular profile 6 has a height h₁ that is preferably comprised between approximately 20 mm and approximately 60 mm, and more conveniently is equal to approximately 40 mm.
It is further understood that the support frame 2 may have a shape different from a rectangular shape, such as for example square, trapezoidal or the like, and/or may comprise two or more tubular profiles 6.
In particular, in an alternative embodiment of the invention, the support frame 2 may comprise a pair of C-shaped tubular profiles 6 mutually fixed to each other at the head or four L-shaped tubular profiles 6 and mutually fixed to each other at the head.
In addition, the bed base for ship 1 is preferably provided with a plurality of legs/feet 9 for resting on the ground, which are firmly connected to the bars 4 and/or to the support frame 2.
According to the present invention, the bed base for ship 1 further comprises a plate-shaped/band-shaped containment frame 10, which is integral with the support frame 2 and is dimensioned so as to conveniently carry out the function of mattress retainer. Preferably, the containment frame 10 is rigidly fixed, for example by welding, onto at least two outer sides of the support frame 2 and has at least a first bend K₁-K₄ with a first predetermined radius of curvature R₁ at a relative corner of said containment frame 10.
In the following disclosure, explicit reference will be made without thereby losing generality to a containment frame 10 that is rigidly fixed, for example by welding, onto the four outer sides of the support frame 2.
According to a preferred exemplifying embodiment shown in Figures 1 and 2, the containment frame 10 slightly exceeds the outer dimensions of the perimeter of the support frame 2. The containment frame 10 is rigidly fixed to the outer side walls/sides of the support frame 2 so as to surround and laterally cover/coat the same.
The containment frame 10 can conveniently have a height h₂ comprised between approximately 50 mm and approximately 120 mm, preferably of approximately 70 mm.
According to a preferred exemplifying embodiment shown in Figures 1 and 2, the upper annular edge of the containment frame 10 protrudes vertically in a cantilever fashion over the support frame 2 and/or over the support surface 3 by a predetermined height d₁.
The height d₁ can be comprised between approximately 10 mm and approximately 100 mm, and is preferably equal to approximately 25 mm.
The containment frame 10 has the technical effect of externally covering/masking the support frame 2 so as to improve the aesthetic appearance of the bed base for ship 1. A further technical effect of the containment frame 10 is that of carrying out the function of locking and lateral containment of the mattress, replacing the traditional mattress retainer elements. In fact, the support frame 2 prevents the mattress from moving during the pitching and rolling movements of the boat.
With reference to Figures 1 and 2, the containment frame 10 consists of one or more plate-shaped/band-shaped strips 11 made of metal material with a rectangular section of reduced thickness.
According to a preferred exemplifying embodiment shown in the accompanying figures, the containment frame 10 is formed by four plate-shaped strips 11 rigidly fixed onto the outer side walls of the support frame 2, for example by welding. The strips 11 are substantially shaped in the shape of an L and have respective bends K₁-K₄, preferably right-angled, with a radius of curvature R₁.
According to a preferred embodiment shown in the accompanying figures, the strips 11 are rigidly fixed onto the outer side walls of the support frame 2 so that the relative bends K₁-K₄ overlap the respective bends P₁-P₄ of the tubular profile 6 forming the support frame 2.
According to a possible embodiment, the strips 11 can conveniently be fixed rigidly, for example by welding, to each other at the head.
The radius of curvature R₁ can be comprised between approximately 60 mm and approximately 100 mm, preferably is equal to approximately 80 mm.
Preferably, the radius of curvature R₁ of the bends K₁-K₄ can be smaller than the radius of curvature R₂ of the bends P₁-P₄.
According to a different embodiment, the containment frame 10 can comprise a single strip 11 provided with the four bends K1-K4 so as to be substantially shaped in the shape of a rectangle.
According to a further different embodiment, the containment frame 10 can comprise a pair of strips 11, each of which is provided with two of the bends K₁-K₄ and is C-shaped.
With reference to Figures 3 to 10, the method for manufacturing the bed base for ship 1 having the above-described structure will be described in the following.
The method for manufacturing the bed base for ship 1 object of the present invention essentially envisages the steps of:

pre-arranging one or more preferably rectilinear tubular profiles 6 made of metal material that are intended to form the support frame 2;
making, on the tubular profile(s) 6, one or more bends P₁-P₄ with the radius of curvature R₂ at the points of the tubular profile(s) 6 that are intended to form the corners of the support frame 2;
pre-arranging one or more plate-shaped strips 11 of an appropriate thickness made of metal material that are intended to form the containment frame 10;
making at least one bend K₁-K₄ with the radius of curvature R₁ on the plate-shaped strip(s) 11; and
applying the plate-shaped strip(s) 11 onto the outer side walls of the support frame 2, so that the upper annular edge of the containment frame 10 protrudes in a cantilever fashion over the support frame 2 and/or the support surface 3.

In other words, the method for manufacturing the bed base for ship 1 object of the present invention envisages fixing/positioning the plate-shaped strip(s) 11 on the lateral sides of the support frame 2, so that the upper annular edge of the containment frame 10 protrudes vertically in a cantilever fashion over the horizontal lying plane of the support frame 2.
With reference to Figure 3, the method for manufacturing the bed base for ship 1 preferably envisages, prior to the step of making the bends P₁-P₄ on the tubular profile(s) 6, the step of making the narrowing/bottleneck 7 on the end portion 6a of the tubular profile 6.
In particular, in the preferred embodiment of the invention, the step of making the narrowing on the end portion 6a of the tubular profile 6 preferably envisages the step of deforming, by rolling or pressing, the end portion 6a of the tubular profile 6 so as to locally compress/reduce the transverse dimensions of the end portion 6a.
With reference to Figures 4 and 5, the step of making the bends P₁-P₄ on the tubular profile(s) 6 preferably envisages the step of positioning the tubular profile(s) 6 by means of a preferably pneumatically operated bending machine (or pipe bending machine) 100 that is structured to make the bends P₁-P₄.
The bending machine 100 can comprise, for example, a bending die 101 that has a curved lateral side that has a radius substantially equal to the radius of curvature R₂; and a preferably pneumatically operated bending member 102 that is structured to rotate a portion of the tubular profile 6 at least by an angle substantially equal to 90° so as to make one of the bends P₁-P₄.
In the preferred embodiment of the invention, the method envisages pre-arranging preferably a single rectilinear tubular profile 6 and making the four bends P₁-P₄ on the rectilinear tubular profile 6 so as to shape the tubular profile 6 substantially in the shape of a rectangle.
With reference to the preferred embodiment of the invention illustrated in Figure 6, after making the bends P₁-P₄ on the tubular profile 6, the method further comprises the step of drawing closer and engaging the narrowing portion 6a inside the opposite and facing end portion 6b of the bent tubular profile 6. The method further comprises the step of rigidly joining/fixing, for example by welding, the two end portions 6a and 6b of the tubular profile 6 engaged with each other so as to obtain the support frame 2.
With reference to Figures 7 and 8, the method further comprises the step of pre-arranging four plate-shaped strips 11 that are intended to form the containment frame 10.
The method further comprises the step of making the right-angled bends K₁-K₄ with the radius of curvature R₁ on the plate-shaped strips 11 so as to shape each strip 11 substantially in the shape of an L.
In the illustrated example, the step of making the bends K₁-K₄ on the plate-shaped strips 11 preferably envisages the step of positioning the strips 11 on a preferably pneumatically or electrically operated bending machine 200 and making the bends K₁-K₄ on the plate-shaped strips 11 by means of the same.
According to a possible embodiment, the bending machine 200 can be provided with: a bending roller 201 and at least one bending member 202. The bending roller 201 can have a radius substantially equal to the radius of curvature R₁. The bending member 202 can be pneumatically or electrically operated and be structured to rotate a portion of the plate-shaped strip 11 by an angle substantially equal to 90° so as to make the right-angled bends K₁-K₄.
With reference to Figure 10, the method for manufacturing the bed base for ship 1 preferably envisages, after bending the plate-shaped strip (s) 11, the step of rigidly fixing, for example by welding, the plate-shaped strip(s) 11 onto the lateral sides of the support frame 2 so as to obtain the containment frame 10.
More specifically, the step of rigidly fixing the plate-shaped strip(s) 11 onto the lateral sides of the support frame 2 preferably envisages the steps of:

pre-arranging a moulder (or template) frame 300 that is provided with at least a plurality of first locking members (not visible in the figures) designed to firmly hold the support frame 2 and a plurality of second locking (or clamping) members 301 designed to firmly hold the strips 11 in a pre-set position in abutment against the outer side walls of the support frame 2, or more precisely of the tubular profile 6;
arranging and rigidly locking the support frame 2 or, more precisely, the previously bent tubular profile 6, on the moulder frame 300;
arranging and locking the strips 11 in the pre-set position in abutment against the outer side walls of the support frame, or more precisely of the tubular profile 6;
rigidly fixing, for example by welding, the plate-formed strips 11 onto the support frame 2 so as to obtain the containment frame 10.

In addition, the moulder frame 300 preferably also comprises: an electrically or pneumatically operated welding assembly 302 (only partially illustrated in Figure 9); and an electronic control apparatus (not visible in the figures) that is designed to control/drive the welding assembly 302 based on pre-set algorithms and/or based on electrical detection signals from a plurality of sensors positioned/distributed over the welding assembly 302 so as to perform the pre-set welds on the bed base for ship 1.
The technical effects obtained thanks to the use of a moulder frame 300 specifically structured to receive and rigidly lock the support frame 2 and the strip (s) 11 are those of: ensuring the correct positioning/support of the L-shaped strip(s) 11 on the outer side walls of the support frame 2, or more precisely of the tubular profile 6; and allowing compensating any manufacturing tolerances of the bends P₁-P₄ of the support frame 2, or more precisely of the tubular profile 6.
More specifically, it can occur that the actual radius of curvature of the bends P₁-P₄ of the support frame 2 deviates from the nominal dimensions, i.e. it is smaller or greater than the radius of curvature R₂.
The positioning of the strips 11 by means of the moulder frame 300 allows arranging the strips 11 with extreme precision in abutment against the outer side walls of the support frame 2, or more precisely of the tubular profile 6, potentially also slightly deforming the strips 11 so as to compensate any manufacturing tolerances of the bends P₁-P₄ of the support frame 2, or more precisely of the tubular profile 6.
More specifically, the moulder frame allows pressing the strips 11 with force against the outer side walls of the support frame 2 so that the strips 11 correctly adhere to the outer side walls of the support frame 2, and further have the heads respectively in abutment against each other.
This way, the welding of the strips 11 onto the outer side walls of the support frame 2 is considerably simpler and more precise, and allows obtaining a containment frame 10 with a regular and homogeneous outer surface, lacking discontinuities between the strips 11.
With reference to the preferred embodiment of the invention illustrated in Figure 9, the method preferably envisages the step of positioning the four L-shaped plate-shaped strips 11 in abutment against the side walls of the support frame 2 so that each bend K₁-K₄ of the strips 11 substantially overlaps a respective bend P₁-P₄ of the support frame 2, or more precisely of the tubular profile 6.
In addition, the method preferably envisages the step of firmly holding each strip 11 in the pre-set position by means of the locking members 301 of the moulder frame 300.
With reference to Figure 9, the method preferably envisages the step of rigidly fixing the four plate-shaped strips 11 onto the side walls of the support frame 2, or more precisely of the tubular profile 6, for example by welding. In the illustrated example, the method further preferably envisages the step of rigidly fixing the plate-shaped strips 11 to each other, for example by welding the strips 11 to each other at the head.
The advantages associated with the introduction of the above-described method for manufacturing the bed base for ship 1 are considerable.
Firstly, the bed base for ship 1, thanks to the presence of the containment frame 10, is able to firmly hold the mattress positioned on the support surface 3 so as to prevent the mattress from making undesired movements during the rolling and pitching movements of the boat.
In addition, the pre-arrangement of the moulder frame 300 allows the L-shaped strips 11 to correctly adhere to the outer side walls of the support frame 2 and allows compensating any manufacturing tolerances of the bends P₁-P₄ of the support frame 2, or more precisely of the tubular profile 6, so as to obtain a containment frame 10 with a homogeneous and regular outer surface, i.e. lacking discontinuities between the strips 11.
Finally, it is evident that modifications and variants can be made to the support frame and to the method for manufacturing the support frame described and illustrated in the foregoing without thereby departing from the scope of protection of the present invention.
