DETAILED DESCRIPTION OF EXAMPLES

(33) Reference is made to FIGS. 1-33 of the drawings where examples of the present mattress assembly are schematically shown.

(34) The present mattress assembly includes a main mattress, a supplement mattress 1 and a tubular structure 5.

(35) The supplement mattress 1 may include a main body having two lateral extensions 2 and a footboard extension 3. As it will described in connection with the examples of FIGS. 26-33, a headboard extension 17 may alternatively further be provided.

(36) The main body of the supplement mattress 1 together with the extensions 2, 3 can form an extending surface in a plane completely horizontal. This is carried out by rotating said extensions 2, 3 90 from their vertical position. In addition, the extensions 2, 3 can be also rotated 180 as it will be explained below.

(37) The tubular structure 5 is provided along the perimeter of the main body. Fast opening and closing mechanisms 4 are provided for assembling it. The tubular structure 5 may include a number of tube sections. Specifically it may include two long sections 6 for the assembly of the lateral extensions 2; three central sections 7, one for the assembly of the headboard and two intended for the assembly of the footboard extension 3 and for attaching the footboard extension 3 to the main body; eight short sections 8 for the assembly of angles forming the attachment between the lateral extensions 2 and the footboard extension 3, with the main body. All the tube sections are attached to each other by eight bends 9 and four hinges 10 rotatable through 90 and 180 as shown in FIG. 3. The hinges 10 are positioned in the connecting angles between the main body and the lateral extensions 2 and the footboard extension 3.

(38) The main body of the supplement mattress 1 may include clamps or girths 11 positioned at both sides of its back. Said clamps or girths 11 are intended for coupling the supplement mattress 1 on the main mattress.

(39) Referring now to the examples shown in FIG. 9 (not separately shown but includes and is defined by sub-part FIGS. 9a and 9b), and 10-20 of the drawings, the lateral extensions 2 of the supplement mattress 1 may include solid upholstered bed bases 2a. Said solid upholstered bed bases 2a face each other and keep a separation distance equivalent to the width dimensions of the main mattress. This is carried out by a tubular structure 5. In said examples, the tubular structure 5 may include tube sections lined with fabric intended for coupling L-adjusting tubes, two being positioned on each side and in a opposite position, provided with a hinge 10 at its free end positioned at the ends of solid upholstered bed bases 2a.

(40) The footboard extension 3 in turn may include a solid upholstered bed base 3a. The solid upholstered bed base 3a of the footboard extension 3 is shorter than the solid upholstered bed bases 2a of the lateral extensions 2. The footboard extension 3 has at least two hinges 12 on its inner surface, one arranged at each end, coupled to its corresponding L-adjusting tube 5, provided at one free end thereof with a clamp 13 for coupling with the structural tube 5 of the lateral extensions 2.

(41) The solid upholstered bed bases 2a of the lateral extensions 2 and the solid upholstered bed base 3a of the footboard extension 3 may be provided on the top thereof with a padded reinforcement 14 throughout their length.

(42) The solid upholstered bed base 2a of the lateral extensions 2 and the solid upholstered bed base 3a of the footboard extension 3 may be adjustable in height through a threaded insert 15.

(43) The lateral extensions 2 having the upholstered bed bases 2a may be provided with a coupling hinge joint 16 in its central portion. The footboard extension 3 with the upholstered bed base 3a may further include, in a central portion thereof, a corresponding coupling hinge joint 16. The coupling hinge joint 16 can be actuated, for being raised or lowered, manually or by a remotely controlled electric motor M.

(44) FIG. 21 (not separately shown but includes and is defined by sub-part FIGS. 21a and 21 b), 22 and 23 illustrate one example of a fitted sheet 20 that may be included in the present mattress assembly. The fitted sheet 20 may include an elastic element 21 along its entire perimeter and a main body 22 provided with lateral extensions 4. The elastic element 21 of the fitted sheet 20 prevents it from coming out of the lateral and footboard extensions 2, 3 of the supplement mattress 1.

(45) The ends of the fitted sheet 20 are configured by a cutout 24 forming an angle of 90 and several textile sections 25. The textile sections 25 are provided in the connection between the main body 22 with the lateral extensions 23, with fasteners 26 at their free end. Said textile sections 25 can be passed through slots formed in the supplement mattress 1 such that the free end of said textile sections 25 fits the fitted sheet 20 through fasteners 26. This ensures a perfect placement for when the user extends the lateral extensions 2 of the supplement mattress 1 preventing the fitted sheet 20 from coming out of the lateral extensions 2 of the mattress assembly.

(46) Reference is now made to FIGS. 24-29 of the drawings. As stated above, in this example of the mattress assembly a headboard extension 17 may be provided.

(47) In this example shown in FIGS. 24-29 of the drawings, the tubular structure 5 has two hinges 18 in the connecting angle between the headboard extension 17 and the lateral extensions 2. This allows an angle of rotation for raising the hinged headboard 17 at different fixed positions up to a maximum of 90 relative to the mattress 1. This also allows a security barrier to be formed preventing children, disabled and dependent adults from falling to the ground.

(48) Reference is now made to FIGS. 30-33. In this example, the lateral extensions 2 are configured into several separate areas 2b. The separate areas 2b of the lateral extensions 2 are adaptable to corresponding hinged bases movable as they can be rotated through an elevation angle at different fixed positions up to a maximum of 90 relative to mattress 1. The separate areas 2b of the lateral extensions 2 can be rotated together with the flexible and/or adjustable tube sections 5a of the tubular structure 5.

(49) The frame 5b of the tubular structure 5 corresponding to the lateral extensions 2 may be configured on both sides by several separate hinged areas 5c coincident with the above mentioned separate areas 2b. Hinges 5d are attached to the other hinge 5d that is adjacent to a linear slope equivalent to the supplement mattress thickness. This prevents different parts from overlapping each other as they are hinged, enabling a complete adaptability to hinged bases.

(50) The flexible and/or adjustable sections 5a provided on the perimeter in the tubular structure 5, in the footboard extension 3, headboard extension 17 and lateral extensions 2 enable a perfect adaptation of the tubular structure 5 to the supplement mattress 1.

(51) The flexible and/or adjustable tube sections 5a of the tubular structure 5 may be configured with an elastic material or any other equivalent structure facilitating the tubular structure 5 to be folded.

(52) Although only a number of particular examples of the present mattress assembly have been disclosed herein, it will be understood by those skilled in the art that other alternative examples and/or uses and obvious modifications and equivalents thereof are possible.

(53) For example, an automation driving system could be provided for driving the lateral extensions and/or the footboard extension and/or the headboard extension, and/or the tubular structure of the present mattress assembly. This driving system could include the above mentioned electric motor M for driving said extensions and/or the tubular structure and it could be remotely actuated by the user. Remote control could be performed through a control unit having e.g. an appropriate user interface or through a suitable mobile application.

(54) The bed bases 2a, 2b of the lateral extensions 2 and the bed bases 3a of the footboard extension may be provided with at least two hinges at the ends of its back, positioned one at each end, provided with a coupling hinge joint 16 in different positions other than the central portion. Alternative structures and/or methods for raising and/lowering the coupling hinge joint 16 other than manually or by the remotely controlled electric motor M are not ruled out.

(55) Furthermore, the tubular structure could be made of solid tube sections of any shape in cross-section, such as circular, oval, polygonal, etc.

(56) In addition, examples in which the supplement mattress 1 has a single lateral extension are not ruled out. Moreover, there could be examples in which different lateral extensions are provided having different properties and/or functionalities from each other. For example, at least one of the lateral extensions of the supplement mattress could be rigid. Different functionalities of the lateral extensions include areas for holding items, and/or areas for storing items, etc.

(57) On the other hand, the fitted sheet 20 might be provided with upper and lower side channels inside of which an elastic element could be provided so that the side portions of assembly can be suitably wrapped by the fitted sheet 20.

(58) In some examples, the inner central section 7a of the tubular structure 5 shown in FIG. 1 could be not present.

(59) Finally, an additional reinforcing structure could be provided for reinforcing the mattress assembly. This additional reinforcing structure could be adapted for holding the corners of the tubular structure in position.

(60) Therefore, the present disclosure covers many but not all possible combinations of the particular examples of the present mattress assembly described.

(61) Reference signs related to drawings and placed in parentheses in a claim are solely for attempting to increase the intelligibility of the claim, and shall not be construed as limiting its scope. Thus, the scope of the present disclosure should not be limited by particular examples, but should be determined only by a fair reading of the claims that follow.
