    DETAILED DESCRIPTION OF THE INVENTION

    [0047] One embodiment of a multi-membered support apparatus 2, in the form of a slatted frame, that is adjustable by electric motor and used for carrying out an embodiment of the method according to the invention is explained in greater detail with reference to FIGS. 1 through 4.

    [0048] In the illustrated embodiment, the support apparatus 2 has a middle first support part 4 whose ends are connected on the one hand to a second support part 10 that forms an upper body support part, and on the other hand to a third support part 12 that forms a lower body support part, about mutually parallel pivot axes 6, 8, respectively. The connection between the second support part 10 and the first support part 4 on the one hand, and between the third support part 12 and the first support part 4 on the other hand, is designed in such a way that the third support part 12 is foldable onto the first support part and subsequently the second support part 10 is foldable onto the side of the third support part 12 facing away from the middle support part.

    [0049] In the illustrated embodiment, the connection between the first support part 4 and the second support part 10 is established via a first intermediate support part 14 that is connected to the first support part 4 so as to be pivotable about the pivot axis 6. The second support part 10 is connected to the first intermediate support part 14 via a pivot axis 16 that is parallel to the pivot axis 6.

    [0050] In the folded-up state of the mattress (see FIG. 8), the second support part 10 is situated essentially parallel to the first support part 4, the length of the first intermediate support part 14 being selected in such a way that in the folded-up state, including the cushion structure of the mattress, the distance between a facing surface of the second support part 10 and of the first support part 4 essentially corresponds to the thickness of the third support part 12 together with the cushion structure, and the surfaces of the third support part 12 rest against the respective facing surface of the second support part 12 and of the first support part 4.

    [0051] Correspondingly, the connection between the third support part 12 and the first support part 4 is established via a second intermediate support part 18 that on the one hand is connected to the first support part 4 so as to be pivotable about the pivot axis 8. The third support part 12 is connected to the other end of the second intermediate support part 18 via a pivot axis 20 that is parallel to the pivot axis 8, the length of the second intermediate support part 18 being dimensioned in such a way that when the third support part 12, including the cushion structure, is folded onto the first support part 4, the third support part 12 and the first support part 4 are situated essentially parallel to one another (see FIG. 8).

    [0052] An electric motor-driven adjustment apparatus is provided for adjusting the second support part 10 relative to the first support part 4. The design of such electric motor-driven adjustment apparatuses is generally known to those skilled in the art, and therefore is not explained here in greater detail. The electric motor-driven adjustment apparatus may be designed, for example and in particular, as known from EP 2 418 984 B1. However, other designs are also possible, depending on the particular requirements.

    [0053] The electric motor-driven adjustment apparatus is designed in such a way that the second support part 10 together with the cushion structure may be folded onto the first support part 4 (see FIG. 4 and FIG. 8). For this purpose, an adjustment element of the electric motor-driven adjustment apparatus acts loosely on the second support part or on the first intermediate support part connected thereto to allow folding of the second support part 10 onto the first support part 4, beyond the maximally adjusted end position of the adjustment movement defined by the electric motor-driven adjustment apparatus.

    [0054] In the illustrated embodiment, the third support part 12 is foldably connected to the first support part 4 via the second intermediate support part 8 (see FIG. 4 and FIG. 8), but is not adjustable by electric motor. If desired, however, depending on the particular requirements, the third support part 12 may also be adjustable by electric motor relative to the first support part 4.

    [0055] FIG. 2 shows the support apparatus 2 in a perspective view, it being apparent that the support apparatus 2 in this embodiment is designed as a slatted frame. However, other designs are possible. The design and operating principle of such a slatted frame are generally known to those skilled in the art, and therefore are not explained here in greater detail.

    [0056] FIG. 2 shows the support parts in an unadjusted starting position, in which the second support part 10 together with the first intermediate support part 14 in addition to the first support part 4 and the third support part 12 together with the second intermediate support part 18 span an essentially horizontal support plane.

    [0057] FIG. 3 shows the support apparatus 2 in a maximally adjusted end position of the adjustment movement, in which the second support part 12 together with the first intermediate support part 14 is maximally pivoted relative to the first support part 4.

    [0058] FIG. 4 schematically illustrates the folding of the support parts 2, 12 onto one another and onto the first support part 4, with components of the support apparatus 2 omitted for reasons of clarity.

    [0059] FIGS. 5 and 6 illustrate the introduction of the support apparatus 2 into a mattress 28. In the illustrated embodiment, the mattress 28 has a cushion structure 30 which in the illustrated embodiment has at least two horizontal cushion layers situated one above the other, of which only one cushion layer, provided with reference numeral 32, is discernible in FIGS. 5 and 6.

    [0060] The cushion structure has a lower horizontal cushion layer on which the support apparatus 2 is laid, as illustrated in FIG. 6. After the support apparatus 2 is laid on the lower cushion layer, the upper horizontal cushion layer 32 may then be laid on the support apparatus 2, so that the support apparatus 2 is accommodated in a sandwich-like manner between the lower cushion layer and the upper cushion layer 32. The cushion structure 30 together with the inserted slatted frame may subsequently be introduced into a casing of the mattress 28, as illustrated in FIG. 7A.

    [0061] One embodiment of a method according to the invention is explained below with reference to FIGS. 7A through 7F.

    [0062] FIG. 7A shows the mattress 28 in its starting state. To form a compact transport and storage unit, the mattress 28 is introduced into an essentially gas-tight wrapping 34, which in this embodiment is formed by a transparent plastic film.

    [0063] FIGS. 7B and 7C illustrate how the wrapping is pulled over the mattress 28.

    [0064] FIG. 7D shows the mattress in a state in which the mattress 28 is completely accommodated in the wrapping 34.

    [0065] As is apparent from FIGS. 7B through 7D, the second support part 10 has been moved beforehand relative to the first support part 4, into the end position of the adjustment movement, by means of the electric motor-driven adjustment apparatus.

    [0066] A negative pressure device is subsequently connected to the wrapping 34 via a tube 36 and a negative pressure is generated in the wrapping 34, whereupon the cushion structure 30 of the mattress 28 begins to compress.

    [0067] FIG. 7F shows the mattress 28 in a state in which the cushion structure 34 is maximally compressed. In this state, the third support part 12 is folded onto the first support part 4, and subsequently the second support part 10 is folded onto the third support part 12, as indicated in FIG. 7F.

    [0068] FIG. 8 shows the storage and transport unit 36 that is formed upon conclusion of the method. It is apparent that the third support part 12 is folded onto the first support part 4 and the second support part 10 is folded onto the third support part 12, so that the second support part 10 and the first support part 4 are situated essentially parallel to one another, and the surfaces of the third support part 12 rest against the respective facing surface of the first support part 4 and of the second support part 10. In this state, an opening in the wrapping 34 to which the tube 36 has been connected may be sealed gas-tight, for example by heat-sealing the plastic film.

    [0069] It is apparent that a compact storage and transport unit has thus been formed, in which in particular the longest extension defined by the longitudinal extension of the mattress 28 is significantly reduced.

    [0070] Due to its compactness, the storage and transport unit may be easily shipped via a parcel service. For self-pickup by a user, transport is likewise simplified due to the compactness of the storage and transport unit 38, and is easily possible in a passenger vehicle.

    [0071] To simplify the transport even further, the storage and transport unit 38 may be provided with a roller means.

    [0072] FIG. 9 shows one embodiment in which the storage and transport unit 38 is accommodated in an outer container 40 made of cardboard, for example, to protect the wrapping from damage during transport and storage. In the illustrated embodiment, the roller means 2 has two laterally spaced-apart rollers 42, 44 that are affixed to the outer container 40. For this purpose, a holder for each of the rollers 42, 44 may be provided by means of a dowel or a pin-like fastening element that is pushed or driven into the outer container 40.

    [0073] After transport to a user, the user may unpack the storage and transport unit 38 from the outer container 40 and remove the wrapping 34, whereby the cushion structure 30 of the mattress 28 re-expands and assumes its original state, and the support parts 10, 12 may be unfolded. In this state, the mattress 28 is then ready for use.

    [0074] The method according to the invention allows a mattress to be easily and inexpensively prepared for storage or transport by forming a space-saving, compact storage and transport unit.

    [0075] While this invention has been described as having a preferred design, it is understood that it is capable of further modifications, and uses and/or adaptations of the invention and following in general the principle of the invention and including such departures from the present disclosure as come within the known or customary practice in the art to which the invention pertains, and as may be applied to the central features hereinbefore set forth, and fall within the scope of the invention.
