Description: DESCRIPTION SELF RECLINING BED MATTRESS WITH TABLE(S) The invention relates to a self reclining bed mattress with table(s) - reading desk(s) consisting of one, two, three or four reclining parts and a fixed part. The reclining parts fold onto parts of the fixed one, feature autonomous and independent movement and control whereas the fixed part features adapted, autonomous, mobile part(s) with mechanisms that support them and change their position, used as table(s) and reading desk(s). Various types of mattresses are known, made of different materials. Some of them, though not made of the best materials, are bent when fitted onto beds with mobile bases. Others consist of parts and take different positions depending on the movements of the body. These mattresses must be used with a certain type of bed featuring mobile bases so that they can be bent and cannot be used with other types of beds, do not feature autonomous and independent recline up to ninety degrees of one, two, three or four parts according to the user will, nor do they feature attached table(s) and reading desk(s). The invention as described, aims at eliminating these disadvantages and at providing the user with certain advantages. The self-reclining bed mattress with table(s) and reading desk(s) features one, two, three or four reclining parts and a fixed part with one, two, three parts reclining carrier frames and a fixed carrier frame which form its frame; it bears mechanisms for the reclining action, the movement and control of this movement up to ninety degrees of the reclining parts, according to user needs. The reclining carrier frames recline onto parts of the fixed carrier frame, and bear built -in or independent parts of the materials of construction such as the springs, the palm tree fibre material, the rubber, the padding, the fabric, etc. and the fixed carrier frame also bears the remaining materials and one or two autonomous, mobile part(s) with mechanisms for their support and change of position which are used as table(s) and reading desk(s). The advantages stemming from the invention is that the mattress can be made of any material and in any manner, it is suitable for use with any type of bed, features autonomous and independent controlled movement of up to ninety degrees according to user will of one, two, three or four parts, enables the user to relax his feet or his waist or to watch television comfortably, it is aesthetically superior as all its parts are covered with fabric and the reclining mechanisms are not visible, it is fully anatomic featuring spring, rubber or any other material necessary for pleasant and comfortable sleep according to hygienic specifications, it provides the user with the ability to eat or read in the bed comfortably, etc. The double self-reclining mattress features all these capabilities to each user, separately. It bears mobile supports, wheeled or not, and braking mechanisms, other materials may be optionally fitted to its external sides, e.g. wood, metal, etc. bearing different designs, and it can be used in a bed or sofa or may be joined with a similar mattress. A method of application of the invention is described in the sequel with reference to drawings which only illustrate a particular implementation, where: Drawing 1 illustrates a side view and plan view of the self reclining bed mattress with table(s) and reading desk(s). Drawing 2 illustrates the self reclining bed mattress with table(s) and reading desk(s) with the reclining parts in the reclined position. Drawing 3 illustrates a plan view of the fixed carrier frame with the mechanical mechanisms for reclining, movement and control thereof. Drawing 4 illustrates the autonomous mobile part and the mechanisms for support, movement and interchange of position which is used as table - reading desk. Drawing 5 illustrates the floor supports and the mechanism for the support and interchange of position and the mechanical mechanisms for joining the two self-reclining mattresses. Drawings 1, 2, 3, 4 and 5 illustrate a self-reclining bed mattress with a table - reading desk which operates with mechanical movement and mechanical recline control with autonomous and independent reclining action of two parts of it, bearing mechanical mechanisms for reclining and for movement and mechanical mechanisms for the control of this movement, fitted to a frame featuring two reclining carrier frames and a fixed carrier frame, it bears a table-reading desk with mechanical mechanisms for its support and position interchange, it bears floor supports with their mechanical mechanisms and mechanical mechanisms for joining it with another self-reclining mattress. The fixed carrier frame bears two principal longitudinal parallel fixed arms (1) where mechanical reclining and movement mechanisms are attached and joined at their ends with the two other smaller tubular fixed arms at right angles with the first ones (2). The mattress bears at one external side one or more handles (3) which are pushed or pulled and control the motion mechanisms of the recline mechanisms and thus control the degree of recline of the reclining carrier frames and stabilise the reclining part(s) at the user - selected positions. The recline mechanism of each mobile carrier frame is attached to the two principal longitudinal parallel fixed arms, this mechanism enabling reclining up to ninety degrees with a small push or pull of the control handle, each mechanism consisting of a fixed rotating helical shaft (4) at right angles to the shafts, which crosses one of the shafts (5) and is joined with internally threaded rings (6) with two mobile arms (7) joined in a X - shaped formation with a second shaft (8) parallel to the first one, with internally smooth rings (9). The second mobile shaft is attached to and moves on the two principal longitudinal parallel fixed arms of the fixed carrier frame (10); to this shaft, two arms (11) are supported and rotate providing support and recline of the reclining carrier frame and are supported by two other mobile arms supported on them (12) and are rigidly supported on and rotate around the two principal longitudinal parallel fixed arms of the fixed carrier frame (13). The head of the rigidly rotating helical shaft which passes through one principal parallel fixed arm of the fixed carrier frame, bears rhombic teeth (5) coupled to a sprocket (14) which is also coupled to a second larger sprocket (15). This second larger sprocket is connected to a mobile small arm (16) connected to point of another arm (17) which is supported and rotates around the external side of the principal longitudinal parallel fixed arm of the fixed carrier frame; in the sequel, similar arms with connecting arms are connected in succession to the circumference of the principal fixed longitudinal arm and one of the tubular fixed arms of the fixed carrier frame, the last one being joined to the control handle (3). When the control handle is pulled or pushed, the mobile circumferential arms and their connecting arms move the large sprocket multiplying the force exerted by the user, the large sprocket moves the smaller sprocket which in turn rotates the helical shaft. When the helical shaft rotates, the X-crossed arms move and push or pull the mobile shaft connected to them where the arms are supported and turned, whereas they are simultaneously supported with the support arms which are rigidly attached and rotate around the principal parallel shafts of the rigid carrier - frame resulting to a recline of the mobile carrier frame according to user will. The mechanical mechanisms for the support and position interchange of the autonomous moving parts are fitted to the external side of the principal fixed arms of the fixed carrier frame, with two flat surfaces each, pulled on top of one another, used as tables, reader stands or night stands. Each mechanism consists of a longitudinal fixed arm - base (18) where a shaft (19) is attached and moves with a toothed surface in one part where a mechanical arm is fitted for the support and control of the movements of the autonomous mobile part (20). The mechanical arm moves onto its arm - base with a small push of the user forward and backward and bears externally two mobile covers (21) and internally, in longitudinal incisions, two small springs (22) which are attached to one end of the two small bars (23), the other end of which bear arc-shaped internally threaded parts (24) and where each bar is joined with an external cover (25). The lower end of the mechanical arm bears an incision where the shaft of the base (26) passes and the toothed part of the shaft is coupled with the arc-shaped internally threaded part of the lower internal bar. The upper end of the mechanical arm bears an incision where a cylinder of the same thickness and diameter (27) is attached which in the middle of its external surface bears a toothed circumferential part (28) whereto the arc shaped internally threaded part of the upper internal bar is coupled. At the centre, the cylinder bears a cross-shaped incision (29) where a cross-shaped shaft (30) moves freely. The autonomous, mobile flat part (31) is attached to the cross-shaped shaft with a second, mobile cross-shaped shaft (32) connected with rings with cross-shaped incisions (33) which permit the projection of movements to the right and to the left. With reference to its operation, when the lower external case of the mechanical arm is pulled, the internal bar joined to it is also pulled, pressing the spring resulting in a de-coupling of its arc-like internally threaded part by the toothed part of the shaft of the base and permitting the rotation of the mechanical arm. When the lower external case is left free, the arc-shaped internally threaded part of the internal bar joined to it is coupled with the toothed part of the shaft of the base and the mechanical arm is stabilised in the selected position. When the upper external case of the mechanical arm is pulled, the internal bar joined to it is also pulled, pressing the spring resulting in a de-coupling of its arc-shaped internally threaded part from the toothed surface of the cylinder and in permitting its rotational movement and hence the rotational movement of the arc shaped shaft and all the autonomous mobile flat part and is used accordingly as a table or reading desk, whereas its free movement to the left and to the right is allowed, as well as the extension of this movement with the second cross-shaped shaft and connection rings. When the self-reclining bed mattress features two tables - reader desks, the sliding flat surfaces of one of them may be made to couple with the sliding flat surfaces of the other. At the ends of the two principal parallel fixed arms of the fixed frame carrier two arms - bases are fitted parallel to the tubular arms of the fixed carrier frame where straight reclining arms move which are used for the support of the autonomous mobile parts for better support, when heavier objects are placed on them, such as a television set. Flat, wheeled or not, supports (35) are attached to grooved incisions of the two smaller fixed tubular arms of the fixed carrier frame which bear longitudinal bars in four parts (34). They are joined in pairs with cases of the fixed tubular arms of the fixed carrier - frame (36) which bear springs on one side (37) which retain the grooved incisions to the grooved parts of the fixed tubular arms. In so far as their operation is concerned, when one of them is pushed or pulled, the spring is compressed, both floor supports of each side are decoupled from the grooves of the fixed arms and their rotation is permitted so that they may be either stored inside the fixed carrier frame or to assume various support positions and to be stabilised when left free, their grooved support incisions being coupled to the grooved parts of the fixed tubular arms of the fixed carrier frame under the pressure of the springs. Two mechanical mechanisms for joining one self reclining mattress with another are attached with retention screws to receptions at the ends of the principal parallel fixed arms of the fixed carrier frame (38) ; each of the mechanisms consists of four tubular arms, two of which are rectilinear and two of which have the shape of a right angle. Of the former two, one bears internal longitudinal bars whereas the other is internally smooth. Of the angular arms, one bears external longitudinal bars at one part (41) and enters into the respective arm with the respective bars and its other part is externally smooth (42) and enters into one part of the other angular arm which bears a larger incision and is internally smooth (43) whereas the second externally smooth part of the second angular arm (44) enters into the straight arm with the smooth internal surface. In so far as its operation is concerned, at the ends of a principal parallel fixed arm of one of the fixed carrier frames, the two straight tubular arms are fitted with screws to the internal bars. At the ends of a principal parallel fixed arm of the other fixed carrier - frame, the two rectilinear tubular arms are attached with screws to the smooth internal surfaces. The angular arms of each mechanical connection joint couple together and with the respective straight arms of each mechanism. They join two mattresses together , but also permit the removal of one self reclining bed mattresses from another as well as the rotation of one of the two so that it assumes a position vertical to the other, thus creating a sofa stabilised with the penetration of small pins born by parts of the angular arms (45) into receptions of other parts (46).
