Description

[0001] The invention relates to a lying surface device for a bed with the features according to the preamble of claim 1.

[0002] Beds in general, and lying surface devices for beds in particular, are well known from the prior art, which is why a separate printed reference is not required here. Therefore, reference is made only by way of example to DE 696 01 675 T2, which concerns a lying surface device of this type.

[0003] The sleeping surface of a bed serves to hold a mattress, a cushion, and / or the like. In its intended use, the sleeping surface is supported by a bed frame, a bed frame construction, and / or a similar structural component of the bed. A typical design for a sleeping surface is that of a slatted frame. However, other designs are also known from the prior art, such as panel elements made of wood or plastic, mesh structures, and / or the like. Generally, the sleeping surface, in its intended use, serves to hold a mattress, a cushion, and / or the like, with the mattress, cushion, and / or the like resting on the sleeping surface.

[0004] A lying surface device of this type has at least two lying surface elements arranged one behind the other in the longitudinal direction of the lying surface device. The second lying surface element is designed to pivot relative to the first lying surface element.

[0005] In its simplest form, a bed-like device of this type has a first, fixed bed-like element. A second bed-like element, serving as a headboard, is pivotable relative to the first, being mounted either on the first or on a supporting component of the bed. In use, the second bed-like element can be pivoted relative to the first and positioned at an angle to it.

[0006] The reclining system can have additional reclining elements, for example, three, four, or five elements. In the case of five elements, for instance, a central section is provided, to which a backrest and headrest are attached on one side, and a thigh section and lower leg section on the other. The headrest can be pivoted relative to the backrest, and the backrest relative to the central section. Furthermore, the lower leg section can be pivoted relative to the thigh section, and the thigh section relative to the central section. This results in a reclining system whose adjustability meets the highest individual requirements.

[0007] Although these types of bed support systems have proven their worth in everyday practical use, they are not without disadvantages. It has been shown that a gap inevitably opens up between the first and second bed support elements as soon as the second element is moved from its horizontal position to a position inclined relative to the first. In this gap, the mattress held by the bed support system is not supported, and there is also a risk that the mattress will become wedged, at least partially, between the two elements when the second element is pivoted back to its horizontal position.

[0008] In order to avoid the aforementioned problem, the object of the invention is to further develop a lying surface device of the generic type in such a way that the intended mattress reception by the lying surface device is also ensured when the two lying surface elements are pivoted relative to each other.

[0009] To solve this problem, the invention proposes a lying surface device of the type mentioned above, which is characterized by the features according to the characterizing part of claim 1.

[0010] The second lying surface element is designed to support an additional slat body. This slat body is pivotably mounted on the lying surface element, specifically on its transverse side facing the first lying surface element.

[0011] Due to the pivoting arrangement of the support slat on the second lying surface element, the slat can pivot into the gap that opens up when the second lying surface element is pivoted relative to the first. A mattress held by the lying surface system is thus fully supported even when the second lying surface element is pivoted relative to the first, i.e., also in the area of ​​the gap formed between the first and second lying surface elements as a result of the pivoting. The slat, pivoted into the gap, also has the positive effect of preventing the mattress held by the lying surface system from becoming wedged in the gap between the first and second lying surface elements when the second lying surface element pivots back to its horizontally aligned starting position.

[0012] It is provided that a pivot lever is arranged on one end of the strip body and another on the opposite end. The strip body is thus supported by two pivot levers, one on one end and the other on the opposite end. These pivot levers enable the actual pivoting of the strip body.

[0013] The pivot levers interact with joint extensions provided on the second lying surface element. Each pivot lever is pivotably mounted on a joint extension provided by the second lying surface element. The second lying surface element thus provides two joint extensions, each pivotably coupled to a pivot lever.

[0014] It is provided that a guide element is arranged on the pivot lever, opposite the pivot point formed by the articulating extension. This guide element supports the slat body with respect to its edge opposite the axis of rotation defined by the two pivot points. The pivot levers supporting the slat body are thus each supported on one side by the corresponding articulating extension and on the other side by means of the corresponding guide element. According to the invention, the guide element interacts with a support rail, which is provided either by the first lying surface element or by another bed component, for example, a bed frame.

[0015] According to the invention, a pivot lever is further provided with a locking lug that interacts with the associated articulating process. This locking lug ensures that excessive pivoting of the slat body supported by the pivot levers is prevented. From a certain pivot position of the second lying surface element relative to the first lying surface element, the locking lug provided by the pivot lever engages the associated articulating process, thus blocking any further pivoting movement of the profile slat relative to the second lying surface element.

[0016] The slat body provided according to the invention is able to overcome the disadvantages described above in the prior art. The gap that opens up between the first and second lying surface elements when the second lying surface element is pivoted relative to the first lying surface element is closed by the slat body automatically as a result of the pivoting of the second lying surface element relative to the first lying surface element. This advantageously leads to complete support of the mattress held by the lying surface device, even in the area of ​​the gap that forms, i.e., the gap created between the two lying surface elements as a result of the pivoting.In addition, the slat body acts as a crush protection for the mattress, because an unwanted pinching of the mattress between the two lying surface elements when the second lying surface element is swung back relative to the first lying surface element is reliably prevented due to the slat body being swung into the gap between the two lying surface elements.

[0017] According to a further feature of the invention, the slat body is positioned below the first lying surface element when the second lying surface element is not pivoted relative to the first. In the fixed position of the two lying surface elements, they form a completely horizontally oriented lying surface. The two lying surface elements are arranged one behind the other without gaps. In this position, the slat body, which is pivotably mounted on the second lying surface element, is located below the first lying surface element, thus saving space. This means that the slat body, which is additionally provided in contrast to the prior art, does not obstruct the insertion of a mattress by the lying surface assembly.

[0018] When the second lying surface element is pivoted relative to the first lying surface element from its horizontal starting position to an inclined position relative to the first lying surface element, the slat body pivots into the gap that forms between the first and second lying surface elements. The gap that forms between the first and second lying surface elements when pivoting is closed by the slat body pivoting into the gap. The full functionality of the lying surface mechanism is thus completely maintained even when the second lying surface element is pivoted.

[0019] According to a further feature of the invention, the guide element has a roller rotatably arranged on the pivot lever. This allows for low-wear and, in operation, also low-noise guidance of the pivot levers and thus also of the guide body.

[0020] According to a further feature of the invention, the slat body extends across the entire width of the second lying surface element in the transverse direction. The slat body thus has essentially the same longitudinal extent as the associated lying surface element or the slats provided by it. Alternatively, however, it is also possible to extend the slat body only across a portion of the width of the second lying surface element in the transverse direction. In this case, the slat body is preferably aligned centrally with the second lying surface element.

[0021] The invention further proposes a bed, in particular a hospital and / or nursing bed, equipped with a lying surface of the type described above. A bed equipped in this manner offers the advantages already described above.

[0022] Further features and advantages of the invention will become apparent from the following description with reference to the figures. These show Fig. 1 In schematic perspective representation, a section of a bed equipped with a lying surface device according to the invention; Fig. 2 in schematic detail view the lying surface device according to the invention Fig. 1 and Fig. 3 in schematic perspective representation a strip body according to the invention.

[0023] Fig. Figure 1 shows a section of a bed 22 in a purely schematic representation, which in the illustrated embodiment has a bed frame 14. The bed frame 14 serves to hold a lying surface assembly 1, which in turn serves to hold a bed mattress (not shown in the figures).

[0024] The lying surface unit 1 has a first lying surface element 2 and a second lying surface element 3. These two lying surface elements 2, 3 are arranged one behind the other in the longitudinal direction 4 of the lying surface unit 1.

[0025] Each of the two lying surface elements 2, 3 provides slats 16 and 20 respectively, extending in the transverse direction 13. The slats 16 of the first lying surface element 2 are fixedly attached to the bed frame 14. The slats 20 of the second lying surface element 3, however, are supported at their ends by legs 18 and 19 of a frame 17. The frame 17 is pivotally mounted on the bed frame 14, allowing the second lying surface element 3 to pivot relative to the first lying surface element 2.

[0026] According to the invention, a slat body 5 is pivotably arranged on the second lying surface element 3. Specifically, it is arranged on the transverse side of the second lying surface element 3 that corresponds to the first lying surface element 2, as can be seen particularly from the illustration. Fig. 1 equals 1.

[0027] The strip body 5 is held at one end and at the other end by a respective pivot lever 6. For this purpose, a clamp-shaped receptacle, preferably made of plastic, can be attached to the pivot lever 6, into which the strip body 5 is engaged at each end. This relationship is particularly evident from the illustration according to Fig. 2 and Fig. 3.

[0028] Each pivot lever 6 interacts with its associated articulating extension 7 to form a pivot point, the articulating extension 7 being arranged on the second lying surface element 3. This design allows the slat body 5 to pivot on the second lying surface element 3 along a pivot axis extending in the transverse direction 13.

[0029] Opposite the pivot point 8, each swivel lever 6 has a guide element 10. In the illustrated embodiment, the guide element 10 is formed by a roller 12 rotatably mounted on an axle 11. This roller 12 interacts with a retaining rail 15 provided on the bed frame side, on which each swivel lever is supported on the guide element side.

[0030] With the second lying surface element 3 not pivoted relative to the first lying surface element 2, the slat body 5 is located below the first lying surface element 2. In this position of the lying surface elements 2, 3, the lying surface device 1 is horizontally aligned.

[0031] If the second lying surface element 3 is now pivoted relative to the first lying surface element 2 into a position inclined relative to the first lying surface element 2, as is the case in Fig. As shown in Figure 1, a gap 21 inevitably forms between the first lying surface element 2 and the second lying surface element 3. This gap is closed as a result of the pivoting of the second lying surface element 3 relative to the first lying surface element 2 by the slat body 5 which is pivotably arranged on the second lying surface element 3 according to the invention, as follows.

[0032] When the second lying surface element 3 is pivoted, the transverse side of the second lying surface element 3 facing the first lying surface element 2 moves in a direction away from the first lying surface element 2, i.e., with reference to the drawing plane, towards Fig. 1 to the left. The slat body 5 is pulled forward due to its coupling to the second lying surface element 3, sliding along the bed frame-side retaining rails 15 by means of its guide elements 10.

[0033] From a certain pivot angle of the second lying surface element 3, the slat body 5 pivots relative to the second lying surface element 3, thereby pivoting into the gap 21 that opens between the first lying surface element 2 and the second lying surface element 3. In order to prevent the slat body 5 from pivoting too far, i.e., to limit the pivoting movement of the slat body 5, at least one of the pivot levers 6 has a locking lug that interacts with the articulating process 7 associated with the pivot lever 6.
