Description

SUPPORT DEVICE, IN PARTICULAR OF MATTRESS TYPE

The present invention relates to the technical field of support devices configured to form a support for at least a part of the body of a person, mattress type.

Background of the invention

Many mattress-type support devices used for example in the field of camping or hiking are light, portable and foldable for transport. These devices may be (self) inflatable mattresses in which optionally one or more sheets of foam is / are inserted (s). The disadvantage of mattresses using air as a damping means to support at least a part of the body, is that they can suffer a puncture, which is almost irreparable, especially if the repair is as expensive as the support device. Mattresses comprising only one or more sheets of foam are bulky, difficult to compact and therefore bulky.

EP 0.800.355 B1 thus relates to an auto-inflatable mattress comprising a zigzag foam sheet. Said sheet is obtained by making multiple cuts in a foam block, said block is then stretched to form zigzags. The resulting sheet is arranged in the stretched state between two upper and lower impermeable panels. This type of mattress is bulky and difficult to fold, and also has the disadvantage of risk of puncture.

WO 2017/005363 relates to a foldable and transportable camp bed comprising an upper support surface disposed on foldable annular elements. Once the annular elements folded, the support surface and the folded annular elements are folded over each other, such as paving stones, and then housed in a housing used to support a headrest. Such a support device has the advantage of not being inflatable but remains bulky and heavy.

The present invention relates to an indestructible support device since not requiring inflation.

The present invention relates to a support device not advantageously comprising foam, and offering comfort equivalent to inflatable mattresses and / or comprising one or more foam (s) available in the state of the art.

The present invention relates to a support device configured to be folded and therefore adopt a compact volume facilitating its transport and / or storage.

Summary and object of the invention

The subject of the present invention is, according to a first aspect, a support device intended to rest on a bearing surface (S) and configured to constitute a support for at least a part of the body of a person, in particular of the mattress type, said device comprising an upper panel PI and a lower panel P2, and a plurality of intermediate elements, in particular damping elements, arranged between said upper and lower panels thus forming an intermediate layer, in particular damping.

Advantageously, said intermediate elements, in particular damping elements, are blades, in particular longilinear, continuous or discontinuous, comprising portions, in particular long, upper and lower portions, said upper portions being secured in a continuous or discontinuous manner to the upper panel PI and said lower portions being secured continuously or discontinuously to the lower panel P2. In addition, the support device comprises an auxiliary device configured to (i) allow, in a first position, translational movement of the upper panel PI with respect to the lower panel P2; and (ii) preventing, in a second position, translational movement of the upper panel PI with respect to the lower panel P2.

The top panel PI comprises a first upper longitudinal edge and a second upper longitudinal edge.

The lower panel P2 comprises a first lower longitudinal edge and a second lower longitudinal edge.

The support device according to the invention is not inflatable so that it does not risk a puncture. In addition, the blades extending between the upper and lower panels provide a spring effect and therefore damping. These blades are by definition thin, the support device is lightweight.

The upper panels PI and lower P2 respectively are in respective planes NI and N2, said planes NI and N2 being substantially parallel.

The blades are distinct and therefore independent of each other. This arrangement facilitates the folding of the support device.

It is understood by "displacement in translation of the upper panel PI relative to the lower panel P2" the displacement of the panel PI in the plane NI.

Indeed, if PI and P2 panels can move relative to each other, when a user lies on the support device, the thickness of the intermediate layer is reduced and the support device tends to to crash.

One understands by "an elongated blade" any blade whose length is greater than its width.

We understand by a "continuous blade" any blade in one piece.

A "discontinuous blade" is understood to mean any blade in several distinct parts aligned but arranged so as to behave like a continuous blade.

The second securing members 95 and 96 of the first support device 90 and the second securing members 105 and 106 of the second support device 100 are configured to releasably connect the second upper longitudinal edges 91 and 101 to each other on the one hand. upper panels of the first 90 and second 100 devices, and secondly, the second lower longitudinal edges

92 and 102 of the lower panels of the first 90 and second 100 support devices. This arrangement advantageously allows to form a double mattress.

When the support devices 1.30, 50, 90, 100 are in the first position according to the invention, the first and / or second securing members being in the open position, and / or the said spacing member (s) being removed. (s) of the support device, they can be wound on themselves for their storage as shown in Figure 7 for the support device 1.

The support device 1 may also comprise a device for reducing its bulk configuration configured to allow the connection and the engagement of at least a portion of the elongated blades 12 between them as illustrated in FIG. 8.

In this case, at least a portion of the slender blades 12, in this particular example all, are slidably mounted on a link 2, said link 2 being configured so that a traction Tr exerted on the link 2 causes the blades to move together. longilines 12, in particular said longiline blades 12 are arranged so that a traction Tr on said link 2 causes their interlocking.

In the embodiment shown in FIG. 8, the elongate blades 12 comprise left 12c and right 12d openings and a link 2 is passed through the series of left openings 12c then through the series of straight openings 12d and is arranged to form a loop portion 2a opening outwardly from the support device 1 and prehensile by the user.

Link 2 then has an "O" configuration. The free ends 2b and 2c of the link 2 are joined together, and preferably secured by means of a sliding and locking device, for example of the tonka type (not shown).

Sliding of the slender blades 12 is effected in the direction C of the portions 2e and 2f of the link passing through the openings 12c and 12d. When the support device 1 is in the first position according to the invention, the user exerts a traction Tr on the link 2, while maintaining the slender blades 12 in a direction opposite to the traction Tr, then the slender blades 12 slide on link 2 and fit into each other, the support device 1 and adopts a very compact position.

By way of example, the length Lp (see FIG. 2B) in the first or second position of the support device 1 is of the order of 2 m, and advantageously of the order of 40 cm in the third compacted position. The support device 1 is reduced by about 1/5 of its length.

FIG. 9 illustrates the support device 50 comprising a device for reducing its size arranged in the front 51 and rear 52 parts and in such a way as to cause the sliding of the front longitudinal blades 53 to interlock with one another and their interlocking then the sliding of the elongated blades. rear 54 between them and their interlocking.

The front slender blades 53 are slidably mounted on two portions 57e and 57f of a first link 57 and the rear slender blades 54 are slidably mounted on two portions 58e and 58f of a second link 58, the first 57 and second 58 links being configured so that a traction exerted on each of them, while maintaining or pushing the slender blades 53,54 to compact in a direction opposite to the direction Tr, cause the approximation of the slender blades before 53 between them in the front portion 51 and the approximation of the rear slender blades 54 to each other in the rear portion 52. This arrangement facilitates the manual traction Tr that must be performed by the user compared to the sliding of all slender blades 12 for the support device 1 from a single link 2.

The first link 57, compared to the second link 58 having an "O" configuration, has a "U" configuration. The "U" configuration is shown for illustrative purposes, with the "O" configuration being preferred.

In the "U" configuration, the ends 57a and 57b of the first link 56 are abutted, for example by means of a node (not shown), against the left 53c and right 53d openings of the blades 53.

It is also possible that the blades 54 and the blades 53 are arranged in the same direction (which amounts to the arrangement on the device 1) but mounted on different links 57 and 58 in order to facilitate the sliding of the latter and to improve the reducing the size of compacted blades 53,54.

The support device 110, illustrated in FIG. 10, will only be described by its differences with the support device 1 represented in FIGS. 1, 4 and 8. The support device 110 comprises an "O" link 115 having two portions of loops 116 and 117 projecting from the outer face 112 of the support device 110 through a same opening 113 formed in said outer face 112. The portions 116 and 117 are grippable by the user, which exerts a traction on the latter in the direction Tr. arrangement facilitates the interlocking of all the blades 12 in a single traction exerted on the loop portions 116 and 117 without holding the blades in a direction opposite to the direction of traction as is the case in Figure 9.

The blade 120 shown in Figure 11 comprises a series of openings 125, for example having dimensions of the order of 25 mm * 25 mm or 25 mm * 20 mm. The blade 120, compared to the blades 12,33,34,53 and 54, is much lighter. In addition, said openings 125 can be used to pass one or more link (s). The blade 120 can be used in place of or in combination with the blades 12, 33, 34, 54 and 54.
