Another object of the present invention is to improve the comfort and hygienic properties of traditional mattress supports.

STATE OF THE ART PRIOR TO THE INVENTION

Structures for supporting a mattress or small mattress on a piece of furniture intended for resting are known from the state of the art.

Patent WO-1994027548 describes improvements implemented in hospital beds. One of the proposed improvements is provided for allowing the patient to support his/her body on one or the other of the two sets of slats constituting the mattress support, each set being associated with a group of movable elements in an upward and downward direction. Another included improvement is that the mattress support slats can be complemented with a pneumatic chamber located at the top along the entire length of the slat, by fitting together at their ends into side supports that will be later connected to the mattress support crossbar. Thus, it is achieved to cushion the supporting points in the user's body.

Spanish Patent N° 2070083 describes mattress supports that include some pneumatic elements or blisters placed, each one of them, on a lower slat. Said blisters are composed of two cavities in communication with each other through tubes forming part of the blister itself. These are coupled by their ends to side supports that are fitted into the mattress support spars.

Spanish utility model U1018243 describes an elastic platform for beds, equivalent to a conventional mattress support with wooden slats, with the peculiarity that the platform can adapt a flat position and can additionally adapt any warped profile so that it can be used in special positions.

European Patent EP0428227 describes the use of a resistant element for fastening the slats of a mattress support to the frame. The object of the invention comprises two elastically deformable tubular elements connected to each other, these being arranged in parallel, using an elastic part.

DESCRIPTION OF THE INVENTION

The object of the present invention is to provide a suspension structure used in a piece of furniture intended for resting in order to provide a support that adapts to specific needs of each user.

Thus, a suspension structure for supporting a mattress or small mattress in a piece of furniture for resting is proposed, which comprises;

• a support sheet,
• a suspension sheet and
• at least one elastic suspension support placed between both sheets that joins them, and that acts like a suspension mechanism in a vertical direction and as a suspension mechanism in a horizontal direction so as to allow the rocking movement of the suspension structure in the vertical and horizontal directions. The rocking movement of the suspension structure allows it to be capable of adapting to the user's needs and providing flexibility.

The support sheet is located in the bottom part of the suspension structure. The at least one suspension support is positioned thereon, and onto it the suspension sheet is positioned. The suspension sheet is in contact with the mattress or small mattress on the piece of furniture intended for resting wherein the invention is used.

Both the support sheet and suspension sheet may be rectangular and be shaped like a mattress support slat. In this case, the length of the sheets is adapted to the width of the piece of furniture for resting in which it is used, and the width of the sheets is adapted to the measurement of the at least one elastic suspension support. The number of suspension structures to be used depends on the user's needs and the size of piece of the piece of furniture intended for resting wherein it is used.

The support sheet and suspension sheet can have the same shape as the mattress or small mattress of the piece of furniture intended for resting wherein these will be used. In this case, there is more than one elastic suspension support in the suspension structure and the elastic suspension supports are located throughout the entire surface between the support sheet and the suspension sheet. The distribution of the elastic suspension supports will be made according to the user's needs.

In a preferred embodiment, there is more than one elastic suspension support for each suspension structure and the number of elastic suspension supports to be placed in each suspension structure varies depending on the width of the piece of furniture for resting.

Between the space that the at least one elastic suspension support leaves between the suspension sheet and support sheet, the airflows freely towards the outside removing the moisture and the accumulated heat. Thus the comfort and hygienic properties of the whole equipment for resting are maintained, including the suspension structure, the mattress or small mattress and the piece of furniture for resting.

Each of the suspension structures object of the invention is completely covered with a cover. Said cover is made of a breathable fabric and is completely removable.

The cover is custom-built to the suspension structure of the invention. In order to ensure that the cover is completely removable, it is provided with a zipper.

In order to ensure that the cover is completely removable, it can be sewn, or have Velcro or other closing systems.

In a preferred embodiment of the invention, the cover is a 3D mesh fabric between 3 mm and 4 mm thick. In a preferred embodiment of the invention, the cover is a 3D mesh fabric 3.5 mm thick. By using this mesh it is possible for the air to flow through the cover.

In another preferred embodiment of the invention, the cover may be any other breathable fabric such as stretch fabrics or cotton fabrics.

The support sheet acts like a support for the rest of the suspension structure, that is, for the elastic suspension supports and the suspension sheet.

The support sheet is made of a material selectable from the group consisting of wood, plastic, copper, aluminium, steel and any combination thereof.

In a preferred embodiment of the invention, the support sheet is made of multilayered beech wood.

The support sheet may have some mechanization, specifically holes, which are intended for positioning and anchoring the elastic suspension supports forming part of the suspension structure. In a preferred embodiment, there are as many mechanizations as elastic suspension supports. The number of mechanizations in the support sheet may also depend on the number of positioning and fastening elements carried by each elastic suspension support in order to be used with the same.

The suspension sheet acts like a support for the mattress or small mattress.

The suspension sheet may be made of plastic, copper, wood, aluminium, steel or materials with similar properties. In a preferred embodiment of the invention, the suspension sheet is made of wood or plywood.

The support sheet may have some mechanizations intended for positioning and anchoring the elastic suspension supports forming part of the suspension structure. Said mechanizations can be grooves.

In a preferred embodiment, there are two mechanizations for each elastic suspension support in the suspension sheet. In this embodiment of the invention, the grooves are rectangular with rounded vertexes and they are arranged in pairs along the length of the suspension sheet.

In a preferred embodiment of the invention, the at least one elastic suspension support has a hardness of 72 HS. However, the hardness of at least one elastic suspension support can be adjusted in terms of the client's needs. Other hardnesses of 70 HS, 68 HS, 65 HS or 63 HS can be obtained among other values.

In a first preferred embodiment of the invention, the at least one elastic suspension support is defined by two arched wings opposite to each other, one at the top and another at the bottom, defining a spindle-shaped central space and the ends of which come together in some coupling housings wherein a tension member can be placed.

The coupling housings are in communication with the spindle-shaped central space, which at the same time are delimited by some circumferential path curved narrow portions.

The upper arched wing includes an outer "U"-shaped surrounding clamp the free ends of which end in bent ends directed towards the inside.

The lower arched wing includes an outer surrounding clamp larger than the outer surrounding clamp of the upper arched wing, shaped as a reversed "U" the free ends of which end in bent ends directed towards the inside

From the center of the connection between the surrounding outer clamp and the lower arched wing, a cylindrical stub protrudes.

In a preferred embodiment of the invention, the elastic suspension support has some approximate measurements of 10 cm in the horizontal direction, 7.5 cm in the vertical direction, and 3 cm wide.

In this first preferred embodiment, the at least one elastic suspension support shrinks a maximum distance comprised between 2.5 cm and 3.5 cm in the vertical direction. The distance to which the elastic suspension support shrinks in the vertical direction is called comfort stroke. In a preferred embodiment of the invention wherein the elastic suspension supports described in the previous paragraphs are used, this stroke is approximately 3 cm.

In this first preferred embodiment, the suspension structure comprises at least one tension member in the at least one elastic suspension support for adjusting its hardness and thus its comfort stroke.

In an additional preferred embodiment of the first preferred embodiment, said tension member includes a flat body made of elastic material with some extreme thicknessings.

The tension member further includes a larger central orifice flanked by two sets of longitudinally aligned orifices increasing in size towards the ends wherein the extreme thicknessings are located.

The longitudinal edges of the transverse tension member include straight sections pairs coming together towards the center where they are joined in a rounded manner to a pair of circumferential path sections.

The extreme thicknessings of the tension member are designed to be inserted within the coupling housings of the suspension elastic support so that the tension member is transversely positioned in relation to the central space of the suspension elastic support.

In a further preferred embodiment of the first preferred embodiment, the tension member comprises an angular body made of elastic material, the identical branches of which come together in a common connection, from which an outer rib with circular section protrudes.

The branches have a slight bowing on both faces delimiting a decrease in thickness towards their free edges opposite to the common connection for joining both branches.

The extreme corners of the angular body have some cylindrical addendums protruding outside the outer faces of both branches of that angular body.

The outer rib with circular section of the tension member is designed to be inserted into a coupling housing of the elastic suspension support.

The cylindrical addendums have as a function to axially fix the position of the tension member.

In a second preferred embodiment, the at least one elastic suspension support is defined by a top circular base and a bottom circular base defining a central cylindrical body wherein grooves are defined, which pass in a vertical direction extending from the top part of the central cylindrical body to the bottom part.

The top circular base is a flat surface, in the central part of which is a concentric circular bulge in which center there is a rectangular cleft. A first quarter of the flat surface has at least two holes, a second quarter which is adjacent to the first has a through groove that extends following the profile of the concentric circular bulge from said bulge towards the edge of the circular flat surface, a third quarter which is adjacent to the second, is the same as the first quarter and a fourth quarter which is adjacent to the third is the same as the second.

The bottom circular base is the same as the top circular base.

The top circular base can be coupled to the suspension sheet by screws. In a preferred embodiment of the invention, it is coupled by four screws.

The bottom circular base can be coupled to the support sheet by screws. In a preferred embodiment of the invention, it is coupled by four screws.

In this second preferred embodiment, the elastic suspension support measures approximately 9.5 cm in the horizontal direction, 8 cm in the vertical direction and 9.5 cm wide.

In this second preferred embodiment, the at least one elastic suspension support has a comfort stroke between 6.5 cm and 7.5 in the vertical direction. In this preferred embodiment of the invention, this stroke is approximately 7 cm.

Thus, this second preferred embodiment is the best alternative for users who need a longer elastic stroke of the suspension structure or who are heavier.

Preferably, in this second embodiment of the invention at least one tension member is used, which serves for adjusting the hardness of the elastic suspension support, and comprising at least one spring. This tension member is placed inside the elastic suspension support and serves for adapting the hardness to the user's needs or to the different resting areas.

By including a different tension member in each suspension element according to the needs of each person, fully customized suspension structures are obtained. Therefore, if there is for example, a piece of furniture intended for resting with several suspension structures where, in each of which, there are several elastic suspension supports, each one of the supports can be adapted by adjusting its hardness so as to present greater resistance in the user's heavier areas such as in the lumbar area and less resistance in lighter areas such as the extremities. In a preferred embodiment of the invention in which several suspension structures are used as mattress support slats, if it is a double bed, the hardness of the elastic supports can be adapted customizing them at each area to the corresponding user.

In a further preferred embodiment of the invention, at least one elastic suspension support is made of an elastomeric material.

In a further preferred embodiment of the invention, the at least one elastic suspension support is made of TPEE (thermoplastic polyester elastomer).

The described geometries for the at least one elastic suspension support allows it to act as a suspension mechanism in a vertical direction and, at the same time, as a suspension mechanism in the horizontal direction, allowing the suspension structure to rock.

The suspension structure may include a support through which it is fastened to a rack placed in the structure of the piece of furniture for resting. Said support can be used to fasten the suspension structure directly to the structure of the piece of furniture for resting.

In a preferred embodiment of the invention, said support is made of nylon.

The support has some measurements that are adapted to fit the width of the support sheet since the support sheet is the one hooked in said support.

In a preferred embodiment of the present invention, the piece of furniture for resting is a bed.

Another object of the present invention is a bed comprising at least one suspension structure as any of the previously defined.

In a preferred embodiment of the invention, the piece of furniture for resting comprises a sufficient number of suspension structures so as to, when the user lays on the mattress or small mattress, said mattress or small mattress shifts the pressure to the suspension structures of the piece of furniture for resting so that these automatically rock horizontally and vertically to adapt the entire resting surface to the contour needs of the user, providing optimal support for his/her vertical column.

One of the uses of the present suspension structure is as slat for a mattress support.

Another use of the present suspension structure is for placing a mattress or small mattress on it.

Thus, the present suspension structure is preferably used together with more suspension structures as slat in order to form a mattress support for a piece of furniture for resting, which can be a bed or a resting and/or relaxing surface.

In a preferred embodiment of the invention, suspension structures comprising elastic suspension supports as those described for the first preferred embodiment and as those described for the second preferred embodiment are used in a piece of furniture for resting. The possibility of combining both types of elastic suspension supports enables a much higher capacity to adapt to the user's needs.

In a further preferred embodiment of the invention, the support sheet (1) and the suspension sheet (4) may have the same shape as the mattress or small mattress present in the piece of furniture intended for resting. In this case there is more than one elastic suspension support (2, 3), and these are placed all over the surface of the sheets according to the user's needs.

In a further preferred embodiment, the piece of furniture for resting comprises more than one suspension structure and each suspension structure has more than one elastic suspension support (2, 3).

The piece of furniture for resting comprises a sufficient number of suspension structures so that when the user lays on the mattress or small mattress, said mattress or small mattress shifts the pressure (A) to the suspension structures of the bed so that these automatically rock laterally (B) and vertically (C) to adapt the entire resting surface of the mattress support of the piece of furniture for resting to the contour needs of the user, providing optimal support for his/her vertical column.

The space between the support sheet (4) and the suspension sheet (1) is determined by the height of the elastic suspension support (2, 3).

By means of the space between both sheets the circulation therebetween of an airflow (D) removing the moisture and accumulated heat towards the outside keeping the hygienic properties of the entire resting equipment is achieved, including the suspension structure, the mattress or small mattress and the piece of furniture for resting. Figure 1b shows the airflow (D) passing through the free space between the support sheet (1) and the suspension sheet (4).

The suspension structure object of the invention is completely covered with a cover (5). Said cover (5) is a breathable and completely removable fabric. Figure 3 shows the suspension structure object of the invention completely covered with the cover (5).

The cover (5) is custom built to the suspension structure and is provided with a zipper in order to be completely removable.

Said cover (5) is made of a 3.5 mm thick 3D mesh fabric. This mesh allows the airflow (D) to pass through the cover.

The support sheet (1) acts like a support for the rest of the suspension structure, that is for the elastic suspension supports (2, 3) and the suspension sheet (4). The support sheet (1) is made of multilayered beech wood.

The suspension sheet (4) acts like a support surface for the mattress or small mattress. Said suspension sheet (4) is made of wood.

The support sheet (1) may have some holes intended for positioning and anchoring the elastic suspension supports (2, 3).

In a preferred embodiment of the invention, the support sheet (1) has as many holes as elastic suspension supports (2, 3) are provided in the suspension structure.

The suspension sheet (4) may have grooves for positioning and anchoring the elastic suspension supports (2, 3).

In a preferred embodiment of the invention, the suspension sheet (4) has as many pairs of grooves as elastic suspension supports (2, 3) are used in the suspension structure. Said grooves can be rectangular with rounded-vertexes.

The elastic suspension support (2, 3) has a standard hardness of HS 72. However, the hardness of the elastic suspension support (2, 3) can be adjusted in terms of the client's needs. Different hardnesses as 70 HS, 68 HS, 65 HS, 63 HS... can be obtained. To adjust this hardness, a tension member is included in the elastic suspension support (2, 3).

In a first preferred embodiment of the invention, shown in Figure 2a, the elastic suspension support (2) is defined by two arched wings (7, 8) opposite to each other, one at the top (7) and another at the bottom (8), defining a spindle-shaped central space (6). The ends of said arched wings come together in coupling housings (18) wherein a tension member can be placed, and said coupling housings (18) are in communication with the spindle-shaped central space (6), which at the same time are delimited by some circumferential path curved narrow portions.

The upper arched wing (7) includes an outer "U"-shaped surrounding clamp the free ends of which end in bent ends directed towards the inside. At the junction of the upper arched wing (7) and the outer surrounding clamp, a through hole centred according to an upper recess and another opposed lower recess leading to opposite edges is defined.

The lower arched wing (8) includes an outer surrounding clamp larger than the outer surrounding clamp of the upper arched wing, in the form of reversed "U", the free ends of which end in bent ends directed towards the inside and from the center of the lower arched wing (8), a cylindrical stub (10) protrudes. In turn, in the inner face of the lower arched wing (8) a centred recess occupying more than half the width of said wing (8), while leading to an edge of such wing (8), is defined.

The geometry of the elastic suspension support (2) of the first preferred embodiment is clearly shown in Figure 4.

In an even more preferred embodiment, a tension member (12) is provided in the elastic suspension support (2) in order to adjust the hardness of said elastic suspension support (2).

The tension member (12) is defined by a flat body with some extreme thicknessings (19), further including a larger central orifice flanked by two sets of longitudinally aligned orifices (23) increasing in size towards the ends wherein the extreme thicknessings (19) are. The longitudinal edges of the transverse tension member comprise pairs of straight sections coming together towards the center where they are joined in a rounded manner to a pair of circumferential path sections.

The extreme thicknessings (19) of the tension member (12) are designed to be inserted into the coupling housings (18) of the elastic suspension support (2) so that the tension member (12) is transversely positioned in relation to the central space of the elastic suspension support (2).

In order to obtain different hardnesses, the tension members (12) are manufactured with greater or lower thickness, and the number of holes made therein is varied.

The geometry of the tension member (12) used in this preferred embodiment is shown in Figure 5. Figure 7a shows the tension member (12) placed in the elastic suspension support (2).

In a further even more preferred embodiment, a tension member (20) is provided in the elastic suspension support (2) in order to adjust the hardness of said elastic suspension support (2).

Said tension member (20) is defined by an angular body the identical branches of which come together in a common connection, from which an outer rib (21) with circular section protrudes. The branches of the tension member (20) have a slight bowing on both of their faces defining a decrease in thickness towards their free edges opposite to the common connection that joins both branches. The extreme corners of the angular body have some cylindrical addendums (22) protruding outside the outer faces of both branches of that angular body.

The cylindrical addendums (22) have as a function axially fastening the position of the tension member.

In a further preferred embodiment two tension members (20) are added, placing the outer rib (21) of each one of them into one of the coupling housings (18) of the elastic suspension support (2).

The geometry of this tension member (20) is clearly seen in Figure 6 and Figure 7b shows an embodiment wherein two tension members (20) are positioned on an elastic suspension support (2).

In this preferred embodiment of the invention, the elastic suspension support (2) has some approximate measurements of 10 cm in horizontal direction, 7.5 cm in vertical direction and 3 cm wide.

In this first preferred embodiment, the at least one elastic suspension support (2) has a comfort stroke between 2.5 cm and 3.5 cm in the vertical direction, said comfort stroke being about 3 cm.

The provision of the tension members (12, 20) helps to adjust the hardness of the elastic suspension support (2) and varies its comfort stroke.

In this first preferred embodiment, the elastic suspension support (2) is fastened in its position on the suspension structure through its upper arched wing (7) and its lower arched wing (8).

In a further embodiment of this first preferred embodiment, the upper arched wing (7) is useful for fastening the position of the elastic suspension support (2) in relation to the suspension sheet (4). The outer "U"-shaped surrounding clamp of the upper arched wing (7) has two ends, which are the ends of the "U", which are inserted into the grooves with rectangular profile and rounded vertexes in the suspension sheet (4).

In a further embodiment of this first preferred embodiment, the lower arched wing (8) is useful for fastening the position of the elastic suspension support (2) in relation to the support sheet (1). The cylindrical stub (10) of the elastic suspension support (2) is inserted into the holes existing in the support sheet (1) and the outer surrounding clamp of the lower arched wing (8), which is larger than the outer clamp of the upper arched wing (7), couples the support sheet (1) between its ends.

In a second preferred embodiment, the elastic suspension support (3) is defined by a top circular base (14) and a bottom circular base (15) defining a central cylindrical body (13) in which through grooves are defined in the vertical direction extending from the top of the central cylindrical body (13) towards the bottom.

The top circular base (14) is a flat surface in the central part of which is a concentric circular bulge in the center of which is a rectangular cleft. In said top circular base (14) a first quarter of the flat surface has at least two holes, a second quarter which is adjacent to the first has a through groove extending following the profile of the concentric circular bulge from said bulge towards the circular flat surface edge, a third quarter, adjacent to the second, is the same as the first quarter and a fourth quarter, adjacent to the third is the same as the second.

The bottom circular base (15) is the same as the top circular base (14).

The elastic suspension support (3) of this second preferred embodiment can be anchored to the support sheet (1) and the suspension sheet (4) by screws. In a preferred embodiment of the invention four screws are used to anchor the top circular base (14) of the elastic suspension support (2) to the support sheet (1), and four screws to anchor the bottom circular base (15) of said elastic suspension support (2) to the suspension sheet (4).

The elastic suspension support (3) can be used with at least one tension member which is placed inside said elastic suspension support (3). This tension member includes at least one spring.

In this second preferred embodiment, the at least one elastic suspension support (3) has a comfort stroke between 6.5 cm and 7.5 cm in the vertical direction, said comfort stroke being about 7 cm.

Thus, the second preferred embodiment of the invention is the suitable embodiment when a suspension support with a larger comfort stroke is needed or when the user is heavier.

The provision of a tension member in the elastic suspension support (3) assists to adjust its hardness and varies its comfort stroke.

In a preferred embodiment of the invention, the elastic suspension support (2, 3) is made of thermoplastic polyester elastomer.

In a preferred embodiment of the invention, the tension member (12, 20) used in the elastic suspension support (2, 3) is made of thermoplastic polyester elastomer (TPEE).

The geometry of the elastic suspension supports (2, 3) proposed in the present invention allows them to act as suspension mechanisms in the vertical direction (B) and, at the same time, as horizontal suspension mechanisms (C) allowing the suspension structure to rock.

The suspension structure of the preferred embodiments already described also includes a support (16) through which it is fastened to the structure (17) of the piece of furniture for resting. This support (16) is made of nylon.

In a preferred embodiment of the invention, the support (16) has a geometry in which the central part is a vertical flat surface with a horizontal flat extension on which the support sheet leans, and comprises a stiffening element going from the vertical flat surface to the horizontal flat surface and said anchoring means has, at the ends of the horizontal flat extension some clamps by means of which the anchoring of the support sheet is achieved, the vertical flat surface having at least one pivot on the rear face which is pressure-inserted into at least one hole made in a rack which is placed in the piece of furniture for resting. The at least one pivot may be pressure-inserted into a hole made in a structure placed in the piece of furniture for resting.

The suspension structure object of the present invention is intended to support a mattress or small mattress on a piece of furniture for resting, said piece of furniture for resting being a bed.

Another object of the present invention is a bed comprising at least one suspension structure as any of the ones described above.

In a preferred embodiment of the invention, the suspension structure is used as a slat for the mattress support for a piece of furniture for resting.

In a preferred embodiment of the invention, the suspension structure is used to place a mattress or small mattress thereon.
