Description

Technical Field

[0001] The present invention relates to the field of mattresses.

Background Art

[0002] When a couple sleeps together on one arm, the blood vessels and nerves in the arm are compressed, and pain occurs that requires changing positions after several tens of minutes. The radial nerve is involved in the sensory innervation of the hand. It is mainly a motor nerve that enables extension and abduction. If the position is not changed, a person with an arm under the other may experience radial nerve palsy, often called Saturday night palsy. This palsy is reversible.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide a mattress that avoids this drawback.

Means for Solving the Problems

[0004] For this purpose, according to a first aspect of the present invention, an assembly formed by a mattress and an associated device is proposed, the mattress has a groove opening on the sleeping surface, when the associated device is disposed in the groove, it at least partially fills the groove.

[0005] The groove is part of the thickness of the mattress. The groove does not reach the surface on the opposite side of the sleeping surface. Of course, if the mattress has two sleeping surfaces, for example, a summer surface and a winter surface, one or more grooves can be provided on one and / or the other of the two surfaces. Thus, the assembly has a configuration in which the mattress has a groove through which an arm can pass and a configuration in which the groove is at least partially filled for normal sleep.

[0006] According to one embodiment, the related device has a structure complementary to the groove, and when the related device is installed in the groove, it completely closes the groove. According to one possibility, the related device has a surface that is flush with the sleeping surface when installed in the groove. According to another possibility, the related device is provided with a protruding portion on the sleeping surface. Preferably, the assembly according to the first aspect of the present invention can include a system for attaching the related device to the mattress.

[0007] In one embodiment, the related device is inflatable. For this purpose, the assembly can further include an inflation motor arranged to inflate the related device. According to one possibility, the inflation motor can be housed in the related device. According to another possibility, the inflation motor may be installed away from the related device, and the related device is provided with an inflation port designed to be fluidly connected to the inflation assembly. The mattress may be equipped with an inflation duct leading to the groove, and the inflation duct is designed to connect to the inflation port. The mattress may include an inflation motor therein. Alternatively, the mattress may be provided with an inflation port fluidly connected to the inflation duct.

[0008] According to the second aspect of the present invention, there is proposed a box sheet for two or more parts provided for the mattress assembly according to the first aspect of the present invention, or for one or more improvements thereof.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Since the embodiments described below are not essentially limiting, in particular, when the selection of this feature confers a technical advantage or is sufficient to distinguish the invention from the prior art, it is possible to consider a variation of the present invention that includes only the selection of the described features. If this selection alone confers a technical advantage or is sufficient to distinguish the invention from the prior art, this selection includes at least one preferred functional feature that does not include structural details or includes only a part with structural details.

[0011] Referring to Figures 1 and 2, an assembly 1 formed by a mattress 2 and related devices 3 is proposed. The mattress has a length, also referred to as the longitudinal direction, and a width, also referred to as the transverse direction. The longitudinal direction and the transverse direction define a plane parallel to the sleeping surface of the mattress. The mattress further has a thickness in a direction perpendicular to both the longitudinal direction and the transverse direction. The mattress has a groove 4 on the sleeping surface 5.

[0012] As is apparent in FIG. 1, the groove 1 is partial in the transverse direction. In other words, the groove does not lead to the side edges of the mattress. Since the groove is partial, there is only one compartment instead of three, so when sitting on the side edge of the mattress at the height of the groove, the mattress is more comfortable. The mattress according to the present invention makes it possible to maintain the height of the edge of the mattress and the associated device for a longer period (avoiding settlement or sagging) when repeated pressure is applied to the edge.

[0013] The associated device 3 is enclosed by five surfaces and is thus movable only along one axis perpendicular to the sleeping surface. This prevents the associated device from moving away from the groove or sliding to the side when a frictional force is applied to the long axis of the associated device when an individual rotates. This also helps prevent the mattress from being damaged immediately by the force applied to the fastener. According to another embodiment, the groove may lead only to the inner edge in the case of a double bed with two juxtaposed mattresses (described later).

[0014] As can be particularly seen in FIG. 2, the associated device 3 can have a shape that is exactly complementary to the shape of the groove 4. As is apparent in FIG. 2, the groove 1 is a part determined by the thickness of the mattress. The associated device is designed to at least partially fill the groove when it is installed in the groove. The associated device is, for example, a cushion. The associated device can be formed from one or more complementary parts. Thus, it is possible to place one or more associated devices or cushions in the groove. Thus, as can be well seen in Figure 3, the assembly has a configuration with a groove provided for the mattress to pass through the arm, and a configuration that at least partially fills the groove to enable typical sleep.

[0015] The groove 4 is formed in the lateral direction of the bed. As shown by the groove 4' in Figure 1, there can also be other directions. The groove may have different dimensions, different shapes, be straight or non - straight, lateral, or at different angles. The mattress 2 may have one or more grooves 4. The related device 3 completely or partially fills the groove 4. It may be formed of any material (one or more) that is hollow or solid, of any shape, any size, and inflatable or non - inflatable.

[0016] Referring to Figure 4, different attachment systems 6, 6', 6'' of the related device 3 on the mattress are shown. The attachment system 6 holds the related device 3 so that it does not fall when the mattress moves. Various types of attachment systems are provided, such as knots, surface fasteners, zippers, buttons, etc. The materials may be different. The attachment system 6 is provided between the mattress 2 and the related device 3 by a link that starts from the mattress 2 and surrounds the related device 3. The link is tightened by a knot. The attachment system 6' is provided between the mattress 2 and the related device 3 by two surface fasteners that start from the sleeping surface of the mattress 2 and prevent the removal of the related device 3 when they are fixed to each other. The attachment system 6'' is provided between the mattress 2 and the related device 3 by a surface fastener installed in the related device 3 and in the groove 4.

[0017] Referring to Figure 5, a box sheet 7 according to the present invention is shown. The box sheet 7 has two or more parts 7', 7'', 7''' etc. One or more parts 7' are provided to cover the mattress 2 of the assembly. Part 7' is provided with one or more parts that follow the shape and dimensions of the grooves 4 on the mattress 2. This part can be made from one or more fabrics, especially for the grooves 4. Part 7' may have one or more large holes of the same shape as the grooves 4, especially in the case of an impermeable box sheet. Part 7' can have one or more large holes at the bottom of the grooves 4 to connect between the grooves 4 in the case of a tunnel (described later) that allows the passage of the arm. Part 7' may have small extensions at the bottom of the grooves 4 to cover the walls of the tunnel that allows the passage of the arm. Part 7' can have small holes that allow the attachment system 6 to function properly, and holes that allow the inflation system (described later) to pass through. Other parts 7'', 7''', etc. are provided to cover the related devices 3, 3', 3'a, etc.

[0018] The related device 3 can be inflatable. According to one embodiment described with reference to FIG. 6, the assembly 1 may include an inflation motor 8 arranged to inflate the related device 3. As shown, the inflation motor 8 is arranged away from the related device 3. The related device is provided with an inflation port designed to be fluidly connected to the inflation motor. More precisely, the inflation motor 8 is arranged inside the mattress 2. The assembly 1 further includes a duct 9 that opens into the groove 4 and is intended to be connected to the inflation port. The duct 9 can be made non-collapsible. Otherwise, the duct 9 passes through a sheath 10 that is resistant to crushing. The related device 3 does not completely detach from the mattress 2 and thus expands and contracts within the groove 4. The leak prevention system 11 can be arranged at one end of the air intake of the inflation motor 8, at the related device, and at the ends of the duct. According to a variant of the invention not shown, the inflation motor 8 may be away from the mattress 2, in which case the mattress has an inflation port. According to a modification of the present invention not shown, the inflation motor 8 can be attached to the related device 3. According to a modification of the present invention not shown, an overpressure valve can be provided in the inflation port of the related device 3.

[0019] The related device 3 may be removable from the mattress 2. Referring to FIG. 7, it should be noted that different forms of the related devices 3' and 3'' are possible. The device 3' is inflatable and, when inflated, has a portion that protrudes in the form of a futon or other shape. The device 3'' is not inflatable and may have a configuration that complements the configuration of 3', thus creating a stack of related devices. Therefore, when the device 3' is inflated, the stack may protrude from the sleeping surface. One or more related devices 3, 3'', etc. can be installed in the same groove 4. The related device according to the present invention can include one or more pieces of cloth arranged towards the outside of the mattress when placed in the groove so as to be more easily pulled out of the groove. Some devices 3, 3' or 3', etc. can be completely separated or adhesively bonded completely or partially (by surface, point, edge, etc.). Some devices 3, 3', 3'', etc. can be placed on the same mattress together or separately.

[0020] FIG. 8 shows the case of a double bed formed by two juxtaposed mattresses 2a, 2b. The groove can be formed and installed across the two mattresses by two half - grooves 4a and 4b, so that it is in contact with the inner edges without opening at the side edges of the two juxtaposed mattresses. The groove may be filled by two or more related devices 3a and 3b, etc., or by a single related device 3c.

[0021] In the variant shown in FIG. 9, the related device of the mattress 2’ is formed by three juxtaposed parts 3’a, 3’b, 3’c. As shown in the figure, the middle part 3’b may have, for example, a hole in the form of a tunnel through which an arm can pass. In the variant shown in FIG. 10, it has been proposed that the mattress 200 has two grooves 400a, 400b separated by a central part 200’ of the mattress. The central part has a predetermined width and comprises a tunnel connecting the two grooves. Thus, the arm can pass through the tunnel. Rigid type mattresses and inflatable type mattresses are known. Although both types of mattresses are targeted, the present invention has also found certain advantages in rigid type mattresses.

[0022] Of course, the various features, forms, variants, and embodiments of the present invention can be combined with each other in various combinations as long as they are not incompatible or exclusive of each other. In particular, all of the above variants and embodiments can be combined with each other.
