Slatted frame

Description

[0001] The invention relates to a slatted frame, in particular for a bed, comprising a headboard supporting at least the head of a person and a footboard supporting at least the legs and feet of a person. The headboard is pivotable relative to the footboard about a rotation axis extending transversely to the longitudinal extension of the headboard and footboard. Mattress supports in general and slatted frames in particular are known per se from the prior art, which is why a separate printed reference is not required here.

[0002] When used as intended, a mattress support serves to support a mattress, typically a bed mattress. The mattress support can be plate-shaped, a grid-shaped, or designed in some other way. A frequently used design is the slatted frame. This typically has a plurality of individual slats arranged at a distance from one another along the length of the mattress to be supported. Designs are also known in the art in which the slats of a slatted frame are equipped with individual spring elements on the mattress side. This can further increase sleeping comfort.

[0003] A slatted frame or mattress support of this type has a headboard and a footboard. When used as intended, the headboard serves to support at least the head, while the footboard serves to support at least the legs and feet. The headboard is typically shorter than the footboard in the longitudinal direction of the headboard and footboard.

[0004] According to a generic slatted frame or a generic mattress support, it is further provided that the headboard is pivotable relative to the footboard, specifically about a rotation axis running transversely to the longitudinal extent of the headboard and footboard. This pivotability allows the headboard, when the slatted frame is used as intended, to be moved from a horizontal position to a position inclined relative to the footboard. A person supported by the slatted frame thus no longer assumes a lying position, but rather an upright position depending on the angle of inclination. Generic slatted frames or bed constructions having a generic mattress support are known, for example, from WO 2017 / 108626 A1, US 5 685 034 A, and US 9 038 218 B1.

[0005] WO 2017 / 108626 A1 discloses a frame structure for a bed, wherein the frame structure comprises several sections for accommodating a mattress. The sections can be divided into both head-end and foot-end sections, with the head-end and foot-end sections each pivotable about a rotation axis. Furthermore, the head-end sections are translationally movable in the longitudinal direction of the bed, which is intended to prevent compression of the mattress.

[0006] US 5,685,034 A discloses a hospital bed. The bed comprises a frame and several sections, each of which can be divided into head-end and foot-end sections, each pivotably mounted on a pivot axis. The head-end section can be moved translationally in the longitudinal direction of the bed. This translational movement can create a gap between the foot-end and head-end sections, allowing for the proper positioning of a bedpan.

[0007] Furthermore, US Pat. No. 9,038,218 B1 discloses a bed that is particularly used for patient transport. For this purpose, the bed has a chassis, a lifting device, and a plurality of adjustable sections that allow for mattress accommodation. The sections can be divided into head-end and foot-end sections and can also be pivoted via pivot axes. The sections are arranged on a carriage that can be moved longitudinally along the bed. This design allows a patient to perform movement exercises.

[0008] Although the mattress supports described above have proven themselves in everyday practical use, particularly in the form of slatted frames, there is a constant desire for improvement. TaskThe invention is to further develop a slatted frame or a similar mattress support in such a way that increased comfort of use is achieved.

[0009] To Solution To achieve this object, the invention proposes that the inner frame has longitudinal beams which, on their outer side facing the outer frame, carry U-profiles which serve to accommodate slats in a movable manner.

[0010] The slatted frame according to the invention has a head section which is not only pivotable in relation to the foot section, but is also designed to be movable in translation.

[0011] The translational movement of the headboard in relation to the footboard is possible in the direction of the longitudinal extension of the headboard and footboard, whereby "longitudinal extension" in this sense means the longitudinal extension of the headboard and footboard when the headboard is not pivoted, thus the longitudinal extension of the slatted frame.

[0012] The foot section is designed to be at least partially stationary in the translational direction of the head section, for example, by supporting the slatted frame providing the head section and foot section within a bed frame. Unlike the foot section, the head section is not stationary, but rather, according to the invention, can be moved relative to the foot section, namely, rotated on the one hand and displaced on the other.

[0013] When the headboard pivots towards the footboard, the prior art inevitably results in a V-shaped arrangement of the headboard and footboard. In this area, a mattress lying on the slatted frame is compressed, which can lead to damage to the mattress or even destruction. According to the invention, such compression is minimized by the headboard also moving translationally during a pivoting movement. The possibility provided by the invention of being able to move the headboard translationally back and forth is therefore used to move the headboard away from the footboard when the bed is raised or to move the headboard towards the footboard when the bed is lowered. The headboard is designed to be movable longitudinally relative to the footboard, in particular depending on a rotational position.This creates a synergistic effect, as the headboard's translational movement can be used to adjust the distance between the headboard and footboard in the longitudinal direction of the slatted frame if the headboard is twisted. This, as described above, helps protect the mattress and extends its lifespan. Furthermore, the change in distance when the headboard is pivoted creates a more comfortable sitting position for a person sitting or lying on the mattress.

[0014] Furthermore, the slatted frame according to the invention has a frame which supports the headboard and the footboard, the frame having an outer frame and an inner frame.

[0015] A frame serves to accommodate and support both the headboard and the footboard. According to the invention, this frame is constructed in two parts and has an outer frame on one side and an inner frame on the other, with the inner frame surrounded by the outer frame.

[0016] As will be explained in more detail below, the division of the frame into an outer frame and an inner frame makes it possible in a simple construction to design the head section so that it can be both pivoted and moved translationally in relation to the foot section. According to the prior art according to DE 10 2018 009 934 A1, a one-piece fixed frame is used which movably accommodates the foot section designed as a running frame. In contrast to this, the fixed frame according to the invention is not designed as a single piece, but instead has an inner frame on the one hand and an outer frame surrounding the inner frame on the other. In the finally assembled state, the outer frame and the inner frame jointly support both the head section and the foot section.

[0017] According to the invention, the inner frame also has longitudinal beams that carry U-shaped profiles on their outer side facing the outer frame, which serve to accommodate the slats in a movable manner. The inventive design thus enables a simplified arrangement of the slats on the frame, on the one hand, and simplified accessibility of the slats themselves, on the other.

[0018] According to a preferred feature of the invention, a drive unit is further provided, which is operatively connected to the headboard. This drive unit is configured to move the headboard translationally back and forth relative to the footboard. During normal operation, a driven movement of the headboard relative to the footboard occurs, whereby the headboard is moved translationally away from the footboard and, at a later point in time, toward the footboard, or vice versa. This enables a particularly comfortable transfer of the slatted frame from a lying position to a sitting position and vice versa.

[0019] Relative translational movement of the headboard and footboard is not unknown in the prior art. For example, DE 10 2018 009 934 A1 discloses a slatted frame construction which, in contrast to the present invention, features a fixed headboard and a footboard that is movable relative to it. However, this previously known construction is not without disadvantages, which is why, in contrast to this prior art, the invention proposes moving the headboard rather than the footboard.

[0020] According to the prior art according to DE 10 2018 009 934 A1, the footboard moves relative to the headboard because the motor intended to drive the footboard is located in the area of ​​the footboard and not in the area of ​​the headboard. This enables a direct connection of the motor to the footboard to be moved during intended use. The motor is located in the area of ​​the footboard to prevent unwanted noise and / or vibration transmission to the headboard. According to the prior art according to DE 10 2018 009 934 A1, it is therefore explicitly proposed to move the footboard so that the motor can be easily mounted on the footboard side of the bed frame to achieve an advantageously minimized noise and vibration transmission to the headboard.

[0021] In contrast to the prior art, the design according to the invention provides for the head section rather than the foot section to be movable, thereby deliberately accepting the disadvantage of a more complex construction. This is because the design according to the invention makes it possible to design the foot section in a simplified construction consisting of several sections that can be pivoted relative to one another. The design according to the invention thus achieves the synergistic effect of, on the one hand, realizing relative mobility between the head section and foot section and, on the other hand, forming the foot section from several sections that can be pivoted relative to one another, thus enabling particularly comfortable transfer of the slatted frame from a lying position to a sitting position and vice versa. The slatted frame according to the invention is therefore particularly suitable for use in combination with hospital and / or nursing beds.

[0022] The construction according to the invention makes it possible to pivot the headboard relative to the footboard in a conventional manner. Furthermore, it is possible to move the headboard translationally relative to the footboard. Since, in contrast to the prior art, it is the headboard that is moved, not the footboard, the construction according to the invention also makes it possible to construct the footboard not as a single piece, but instead to provide a plurality of sections that are pivotable relative to one another. The slatted frame according to the invention can therefore be adjusted as needed to assume a corresponding sitting and / or lying position.

[0023] For the purpose of transmitting movement from the slatted frame according to the invention to a person using the slatted frame, a mattress is preferably used that has a buffer section that separates a mattress-side headboard from a mattress-side footboard. A movement of the headboard of the slatted frame can thus be transmitted to a person lying on the slatted frame with the mattress in between.

[0024] According to a further feature of the invention, the drive unit comprises a motor assembly located on the footboard. The motor assembly is preferably located in the area of ​​the footboard to prevent unwanted noise and vibration transmission toward the headboard.

[0025] According to a further feature of the invention, it is proposed in this context that the drive unit comprise a gear arrangement coupling the head section to the motor assembly. This gear arrangement couples the movement of the motor assembly and the head section, so that, when used as intended, the head section can be driven by the drive unit in the manner described above. In contrast to the prior art, the disadvantage of a gear arrangement required to transmit power to the head section is deliberately accepted in order to achieve the additional advantage of being able to design the foot section to be separately adjustable.

[0026] A further advantage is as follows. In the longitudinal extension of the slatted frame, the head section is preferably shorter than the foot section. This means that the head section also has less mass than the foot section, which advantageously allows for a smaller motor arrangement. In addition, the design according to the invention is less susceptible to wear due to the movable arrangement of the head section and not the foot section, since the foot section has to absorb the main load by supporting the weight of a person lying on the slatted frame during normal use. The design according to the invention can therefore be made much more delicate than the prior art design, while increasing its service life. The use of a gear arrangement as described above can prevent unwanted noise and vibration transmission to the head section.

[0027] According to a further feature of the invention, it is provided that a further drive device is provided which is operatively connected to the head part and is designed to pivot the head part in relation to the foot part about the axis of rotation running transversely to the longitudinal extent of the head and foot parts.

[0028] To simplify handling during intended use, an additional drive unit is provided. This is operatively connected to the head section and enables motorized pivoting of the head section relative to the foot section.

[0029] According to a particularly preferred embodiment of the invention, a control device is provided which is configured to move the headboard translationally by means of the first drive device as a function of a pivoting movement of the headboard caused by the second drive device. This advantageously creates a mattress balance that prevents unwanted compression of the mattress when the headboard is pivoted. This extends the lifespan of a mattress and improves the lying and sitting comfort of a person using the slatted frame as intended.

[0030] According to a further feature of the invention, the headboard, in the non-pivoted position, is spaced apart from the headboard and footboard in the longitudinal direction by a minimum distance. The gaps between the headboard and footboard are thus minimized for precise and secure accommodation of a mattress.

[0031] According to a further feature of the invention, the headboard, in the fully pivoted position, is spaced apart from the headboard and footboard in the longitudinal direction as far as possible. This provides the maximum possible mattress compensation, which, as already described, contributes to minimizing stress on the mattress caused by pivoting of the headboard.

[0032] The particular advantage of the design according to the invention is that it enables a translational displacement movement of the headboard as a function of a rotational movement of the headboard. The further a headboard is pivoted, the further a translational displacement movement of the headboard takes place. The headboard moves away from the footboard when the headboard is raised, whereas it moves towards the footboard when it is folded down into a horizontal position. The angle-dependent displacement movement can be predetermined by control technology. This makes it possible, in particular, to provide a need-based dependency rather than a proportional dependency, particularly with regard to the mattress used. In particular, it is possible to provide a displacement movement of the headboard when it is raised. This decreases as the angle increases.In the lower angle range, a movement takes place over a greater distance than in the upper angle range.

[0033] According to a further feature of the invention, the footrest comprises a plurality of sections pivotable relative to one another. In particular, three, four, or five sections may be provided. It is preferred that the sections be pivotable by motors, with one motor preferably being provided for each section, which allows all sections of the footrest to be pivoted independently of one another. This allows any desired sitting and lying position to be achieved.

[0034] According to a further feature of the invention, one of the sections of the foot section is stationary, with the head section being adjacent to this section. Preferably, the section of the foot section that supports the buttocks of a person using the slatted frame as intended is stationary. In this case, the head section supports the upper body and head, whereas the foot section supports the thighs, lower legs, and feet. Due to the adjustable nature of the foot section, the desired orientation of the thighs, lower legs, and feet can be achieved.

[0035] According to a further feature of the invention, a carriage is provided on the inner frame, which can be moved in the longitudinal direction of the frame, with the head part being pivotably mounted on the carriage. The slatted frame according to the invention thus has a two-part frame and a carriage. The carriage is arranged so that it can be moved on the inner frame of the frame. When used as intended, a translational movement of the carriage relative to the inner frame and thus also relative to the frame as a whole is permitted.

[0036] The headboard of the slatted frame according to the invention is mounted on the carriage. This enables the translational movement of the headboard relative to the footboard. Because the headboard is mounted on the carriage, a movement of the carriage also results in a movement of the headboard relative to the frame, and thus also relative to the footboard, which is supported by the frame.

[0037] Since the head section is pivotably mounted on the carriage, it is also possible to rotate the head section relative to the carriage and thus also to the frame. As a result, the head section can be both rotated and moved relative to the foot section in the manner already described. A back-and-forth movement of the head section is possible both in the non-pivoted position of the head section and in the pivoted position of the head section. This is because the movement capability of the head section, on the one hand, and the rotation capability of the head section, on the other, are decoupled from one another in terms of movement. This is due to the fact that the head section is pivotably mounted on the carriage and the carriage is movable on the inner frame.It is therefore permitted to rotate the head section alone in relation to the carriage, to move the carriage together with the head section alone in relation to the frame and / or to rotate both the head section in relation to the carriage and to move the carriage together with the head section in relation to the frame at the same time.

[0038] This possibility of moving the headboard provided by the inventive design allows mattress equalization, i.e., when the headboard rotates, the carriage supporting the headboard also moves, so that a rotational movement of the headboard relative to the footboard does not result in unwanted buckling of the mattress supported by the headboard and footboard in the transition area between the headboard and footboard. The inventive design therefore provides the advantage of implementing automatic mattress equalization between the headboard and footboard. The design previously known from DE 10 2018 009 934 A1 is unable to achieve this positive effect.

[0039] According to a further feature of the invention, it is provided that the foot part section of the foot part facing the head part has slats designed to be movable in the longitudinal direction of the frame.

[0040] As described above, the foot part can have multiple foot part sections. In particular, three foot part sections can be provided: a first foot part section near the head part, a second foot part section remote from the head part, and a third foot part section arranged between the first foot part section and the second foot part section.

[0041] According to the aforementioned inventive feature, the foot section facing the headboard, i.e., the foot section of the foot section adjacent to the headboard, has slats that are designed to be movable in the longitudinal direction of the frame, thus resulting in relative movement of these slats relative to the headboard. The advantage of this design is that, if the headboard twists, an excessive gap between the headboard and footboard can be automatically compensated for by the movable slats of the corresponding foot section moving toward the headboard. This ensures secure buttock support for a person lying in bed or a person lying on the slatted frame.

[0042] According to a further feature of the invention, the movable slats of the foot section are motion-coupled to one another with the interposition of a towing device. The movable slats are thus mechanically coupled to one another, so that a movement of one slat is transmitted to the other slat and vice versa. In this way, a targeted movement of both slats is ensured in a structurally simple manner, without the need for a separate motor drive. Due to the forced coupling provided according to the invention, the preferably two slats move together. The slat adjacent to the head section is motion-coupled to the head section, so that a movement of the head section is transmitted to this slat and then from this slat to the other slat adjacent to it.This ensures that a gap that is too large in the longitudinal direction between the headboard and footboard is not created during any movement of the headboard. In the context of the invention, "too large a gap" means a gap in the transition area between the headboard and footboard that no longer ensures secure support for the mattress held by the slatted frame.

[0043] According to a further feature of the invention, it is provided that the foot part section of the foot part adjacent to the foot part section is arranged on the outer frame so as to be pivotable about an axis of rotation.

[0044] Unlike the headboard, which is mounted on the inner frame with the carriage interposed, the foot section of the footboard adjacent to the headboard foot section is mounted on the outer frame and is rotatable. This rotatable arrangement allows the footboard to be pivoted relative to the frame if necessary, allowing a person supported by the slatted frame to assume a sitting position other than a lying position. This rotatable foot section, mounted on the outer frame, serves in particular to support the thighs of the legs of a person supported by the slatted frame.

[0045] According to a further feature of the invention, the foot section of the foot part adjacent to the foot section rotatably arranged on the outer frame is arranged on this foot section so as to be pivotable about a rotation axis. The foot section of the foot part opposite the head section is therefore not pivotably arranged on the frame on the head part side, but pivotably arranged on the foot section adjacent to it. This foot section serves in particular to support the lower legs of a person accommodated on the slatted frame. As a result of the pivotable design of the foot sections in relation to one another, it is possible for a person accommodated on the slatted frame to bend their lower legs in relation to their thighs.

[0046] According to a further feature of the invention, it is provided that the further drive device which is operatively connected to the head part is carried by the carriage and is supported against an abutment provided by the carriage.

[0047] According to this preferred embodiment of the invention, a drive device is provided that is designed to pivot the head section relative to the carriage and thus also relative to the foot section. The drive device is carried by the carriage, and during movement, it is thus moved together with the head section in a translational manner along the longitudinal extension of the head and foot sections. The drive device is supported against the carriage by means of an abutment provided by the carriage, which, when used as intended, enables a rotational movement of the head section relative to the carriage.

[0048] According to a further feature of the invention, it is provided that the first drive device operatively connected to the head part is supported on the one hand against the inner frame and on the other hand against the carriage.

[0049] The first drive unit, which is operatively connected to the head section, is provided for the translational movement of the head section relative to the foot section. This unit is supported on the one hand by the inner frame and on the other hand by the carriage. When used as intended, a motor-driven relative movement occurs between the carriage and the inner frame, which results in a relative movement between the head section and the foot section, since the head section is mounted on the carriage, meaning that the head section is carried along when the carriage moves.

[0050] According to a further feature of the invention, it is provided that the outer frame has a longitudinal extension that exceeds the longitudinal extension of the inner frame.

[0051] The outer frame preferably extends across the entire length of the slatted frame. The inner frame, however, is shorter because the outer frame has a longer length than the inner frame. The headboard is mounted on the inner frame, not on the outer frame, with the carriage interposed, and is therefore supported by the part of the frame that does not extend across the entire length of the slatted frame. This advantageously results in a functional, structurally simple, and compact overall design. Furthermore, the design decouples all possible movements, allowing the user to perform specific individual movements, even in combination.

[0052] According to a further feature of the invention, the carriage has rollers, each of which engages a U-profile provided by the inner frame. By means of the rollers, a translational movement of the carriage is ensured in the manner already described in a structurally simple design. Furthermore, the rollers provided according to the invention allow a noiseless, yet safe movement of the carriage when used as intended. The U-profiles that accommodate the rollers each serve as rails, thus ensuring a targeted and collision-free movement of the carriage. This design also reliably prevents any unintentional transverse positioning of the carriage in relation to the inner frame.

[0053] According to a further feature of the invention, the slat of the foot section facing the head section is motion-coupled to the head section. The slat of the foot section facing the head section is designed to be translationally movable in the manner described above, so that, due to the motion coupling of the head section and slat, the slat is carried along by the head section when the head section moves. The movement of the slat serves to close an unwanted gap between the head section and foot section, and this, due to the motion coupling between the head section and slat, does not require an additional electric motor drive for the slat.

[0054] Further features and advantages of the invention will become apparent from the following description with reference to the figures.

[0055] Fig. 1shows a schematic representation of a slatted frame 1 according to the invention. This has, in a manner known per se, a headboard 2 and a footboard 3, wherein the headboard 2 is pivotable in relation to the footboard 3 about a rotation axis 5 running transversely to the longitudinal extent 4 of the headboard and footboard 2, 3. "Longitudinal extent" 4 means the longitudinal extent 4 of the headboard and footboard 2, 3 when the headboard 2 is not pivoted, as in Fig. 1 shown.

[0056] Fig. 2 shows in contrast to Fig. 1 a raised headboard 2, that is to say a headboard 2 which is positioned with reference to the drawing plane Fig. 2 is pivoted clockwise in relation to the foot part 3.

[0057] The slatted frame 1 shown in the figures is, for example, a slatted frame 1 for a bed, in particular for a hospital and / or nursing bed. In its final assembled state, the slatted frame 1 is accommodated by a bed frame. In this case, the foot part 3 is fixed relative to the bed frame in its intended use, so that the foot part 3 is stationary in relation to the bed frame. Due to its previously described construction, the head part 2 is movable relative to both the bed frame and the foot part 3, namely pivotable about the rotation axis 5, as can be seen from a summary of the previously explained Figures 1 and 2 results.

[0058] Fig. 3shows that the head part 2 is not only pivotable in relation to the foot part 3, but is also designed to be translationally movable in relation to the foot part in the direction of the longitudinal extension of the head and foot parts 2, 3. The head part 2 can therefore be moved away from the foot part 3, forming a distance A, as in Fig. 3 shown.

[0059] A drive unit 14 is provided which is operatively connected to the head section 2 and is configured to move the head section 2 back and forth in translation relative to the foot section 3. The head section 2 can thus be moved away from the foot section 3 at an increasing distance A and, after reaching its maximum distance A from the foot section 3, can be moved back toward the foot section 3, as a result of which the distance A between the head section 2 and the foot section 3 decreases again.

[0060] The mobility of the head part 2 provided according to the invention can also be combined with each other with regard to the rotatability on the one hand and the movability on the other hand, as shown in Fig. 4 In particular, it is possible to move the head part 2 in the longitudinal direction 4 depending on a rotational position relative to the foot part 3. This creates an automatic mattress compensation, as can be seen in particular from a comparison of the Figures 2 and 4 Through the formation of distances, as in Fig. 4 As can be seen, compression of the mattress, which could potentially damage it, is avoided. Furthermore, a more comfortable sitting and / or lying position is created for a person using the slatted frame 1 as intended.

[0061] The inventive design of the movable head part 2 makes it possible to provide a plurality of sections 6, 7, 8 which are pivotable relative to one another with respect to the foot part 3. This shows Fig. 5 , wherein according to the embodiment shown here, a foot part 3 is provided which has three individual sections 6, 7, 8. The sections 6 and 7 are coupled to one another via a rotation axis 9 and the sections 7 and 8 via a rotation axis 10. The section 7 can thus be pivoted in relation to the section 6 and the section 8 in relation to the section 7, as in Fig. 5 shown.

[0062] As can be seen from the further schematic representation after Fig. 6The head part 2 can have a base body 11 pivotably arranged on the foot part 3. This base body 11 carries a carriage 12 movable in the longitudinal direction 13 of the base body 11, whereby the previously described translational movement of the head part 2 in relation to the foot part 3 is realized.

[0063] A drive unit 14 is provided for the motorized movement of the carriage 12. This drive unit has a motor assembly 20 formed on the foot part, which is force-coupled to the carriage 12 by means of a gear assembly not shown in detail in the figures, as symbolized by arrow 15.

[0064] For the purpose of motorized pivoting movement of the head part 2, a further drive unit 16 with a motor arrangement 21 is provided. This is also coupled to the head part 2 via a gear arrangement, as also symbolized by the arrow 15.

[0065] As a result, the head part 2 can be pivoted about the rotation axis 15 by means of the drive unit 16, specifically with reference to the drawing plane according to Fig. 6 toward the base section 3 for raising and in the opposite direction for lowering. Furthermore, a translational movement of the head section 2 is permitted by motor, whereby in the illustrated embodiment, the carriage 12 is moved relative to the base body 11. The motorized movement is effected by means of the drive unit 14.

[0066] According to a particular proposal of the invention, a control device 17 is provided. This is communicatively connected to the drive units 14 and 16, as symbolized by the arrows 18 and 19. The control device 17 is configured to move the head section 2 translationally by means of the drive unit 14 as a function of a pivoting movement of the head section 2 caused by the drive unit 16. In the illustrated embodiment, the carriage 12 thus moves as a function of the angular position of the base body 11. This creates a gap between the carriage 12 and the foot section 3, depending on the angular position of the base body 11.

[0067] The Figures 7 to 27 reveal a particularly preferred construction of the slatted frame 1 according to the invention.

[0068] As can be seen from Fig. 7The slatted frame 1 has, as already described, a headboard 2 and a footboard 3. These are carried by a frame 22 which is Fig. 15 is shown in more detail.

[0069] In the example shown according to Fig. 7 The foot part 3 has three foot part sections 6, 7 and 8. The foot part sections 7 and 8 are designed to be rotatable, namely the foot part section 7 around the rotation axis 9 and the foot part section 8 around the rotation axis 10.

[0070] As can be seen particularly from the presentation after Fig. 15 The frame 22 has an outer frame 23 and an inner frame 24. The outer frame 23 encloses the inner frame 24 and has an extension in the longitudinal direction of the frame that exceeds the longitudinal extension of the inner frame 24. The outer frame 23 is therefore longer in the longitudinal extension 4 than the inner frame 24.

[0071] In the illustrated embodiment, the outer frame 23 has two longitudinal beams 25 and 26 aligned parallel to one another, which are coupled to one another by means of two transverse beams 27 and 28. Furthermore, an end beam 29 is provided, which connects the longitudinal beams 25 and 26 to one another at one end.

[0072] The inner frame 24, in turn, has the longitudinal beams 30 and 31, which extend between the transverse beams 27 and 28 of the outer frame 23. Furthermore, the inner frame 24 has a transverse beam 32, which connects the longitudinal beams 30 and 31.

[0073] The longitudinal beams 25 and 26 of the outer frame 23 provide extensions 33 and 34 on their inner side facing the inner frame 24. In the fully assembled state of the foot part 33, these extensions form the rotation axis 9 around which the foot part section 7 of the foot part 3 is pivotable. In the fully assembled state, the extensions 33 and 34 thus support the foot part section 7.

[0074] As can be seen from the illustration Fig. 15 Furthermore, the longitudinal beams 30 and 31 of the inner frame 24 carry U-profiles 35 on their inner sides facing one another, which serve to accommodate a carriage 56, which will be explained below, as shown in the Figures 26 and 27 is shown.

[0075] The longitudinal beams 30 and 31 of the inner frame 24 also carry further U-profiles 36 on their respective outer sides facing the outer frame 23. These serve to movably accommodate slats 76 and 82 of the foot part section 6, as will be explained below, in particular with reference to the Figures 20 to 23 will be described later.

[0076] For the purpose of translational mobility of the head part 2, a carriage 56 is provided on which the head part 2 is arranged. The carriage 56 is in the Figures 26 and 27 shown.

[0077] As the representations show, Figures 26 and 27The carriage 56 has two parallel longitudinal beams 57 and 58, which are connected to each other by means of a cross beam 59. The longitudinal beams 27 and 28 each carry two rollers 60. In the final assembled state, these rollers 60 interact with the respective U-profiles 35, which are arranged on the longitudinal beams 30 and 31 of the inner frame 4, as already shown in FIG. Fig. 15 explained.

[0078] The cross member 59 of the carriage 56 provides two abutments 61 and 62, on which drive devices are supported in the final assembled state, namely the drive device 55 on the abutment 61 (cf. e.g. Fig. 8 ) and on the other hand the drive device 63 on the abutment 62 (cf. e.g. Fig. 9 ).

[0079] The longitudinal beams 57 and 58 also provide driving pins 87 and 88, which in the final assembled state each drive a transverse beam 81 of a movable slat 82 (cf. Fig. 23) between them.

[0080] In the final assembled state, the above-described carriage 26 with its rollers 60 is inserted into the U-profiles 35 provided by the inner frame 24, so that the carriage 56 can move translationally in the longitudinal extent 4 in relation to the frame 22, namely back and forth.

[0081] The headboard 2 is in the Figures 24 and 25 It has two longitudinal beams 47 and 48, which are connected to each other by two transverse beams 50 and 51. The longitudinal beams 47 and 48 serve to accommodate a plurality of slats 49 arranged one behind the other in the longitudinal extension 4.

[0082] The cross member 51 of the head section 2 provides brackets 52 and 53. These serve to pivot the head section 2 on the carriage 56, whereby the head section 2 can pivot about the rotation axis 5 defined by the brackets 52 and 53 in the final assembled state. The other cross member 50 of the head section 2 provides an abutment 54 for the drive device 55. In the final assembled state, the drive device 55 is carried by the carriage 56, being arranged between the head section-side abutment 54 and the carriage-side abutment 61. When actuated, the drive device 55 causes a pivoting movement of the head part 2 about the axis of rotation 5 in relation to the carriage 56 and thus also in relation to the frame 22 or to the foot part 3 carried by the frame 22. The foot part 3 is formed in the manner already described from the three foot part sections 6, 7 and 8 arranged one behind the other in the longitudinal extension 4.

[0083] The foot section 8 is formed in the final assembled state opposite the head section 2 and is shown in detail in the Figures 16 and 17 shown.

[0084] As can be seen from the Figures 16 and 17 The foot section 8 has a U-shaped bracket 39. In the final assembled state, this supports slats 40.

[0085] At one end and the other end, the bracket 39 provides tabs 41, which serve for the pivotable arrangement of the foot section 8 on the adjacent foot section 7. In the final assembled state, the tabs 41 define the rotation axis 10, around which the foot section 8 can be pivoted in relation to the foot section 7.

[0086] As can be seen particularly from the presentation after Fig. 17The foot section 8 further comprises a cross member supported by the bracket 39, which provides tabs 70. By means of these tabs 70, the foot section 8 is coupled in terms of movement to the frame 22 with the interposition of coupling elements 69, as can be seen in particular from the illustration according to Fig. 7 The coupling elements 69 are arranged at the other end on a tab 68 provided by the cross member 27 of the outer frame 23, as is particularly shown in the illustration according to Fig. 15 can be recognized.

[0087] The foot section 7, which is articulated to the foot section 8, is in the Figures 18 and 19 As can be seen from these figures, the foot section 7 has two parallel beams 52, which are connected to each other by a cross beam 46. The beams 42 support the slats 43.

[0088] As can be seen particularly from the presentation after Fig. 18 The foot section 7 is equipped with tabs 44 which, in the final assembled state, interact with the corresponding tabs 41 of the foot section 8. The tabs 44 and 41 define, in the manner already described, the axis of rotation 10 around which the foot sections 7 and 8 can be pivoted in relation to one another.

[0089] As shown in particular in the presentation Fig. 19 As can be seen, the spars 42 of the foot section 7 provide holes 45. Through these holes 45, the foot section 7 is hinged to the extensions 33 and 34 in the final assembled state (cf. Fig. 15 ) of the outer frame 23. This enables the previously described rotational movement of the foot part section 7 about the rotation axis 9 defined by the extensions 33 and 34.

[0090] The cross member 46 of the foot section 7 has an abutment 67 in the form of a tab, as can be seen in particular from the illustration according to Fig. 18 In the final assembled state, a drive device 65 is connected to the abutment 87, as can be seen, for example, from the illustration according to Fig. 7 For the purpose of supporting the drive device 65 on the frame side, the cross member 27 of the outer frame 24 provides an abutment 66, as can be seen from the illustration according to Fig. 15 In the intended case of use, a pivoting movement of the foot part section 7 can therefore take place by operating or actuating the drive device 65 and thus also a pivoting movement of the foot part section 8, which is articulatedly connected to the foot part section 7, wherein the foot part section 8 is coupled in terms of movement to the outer frame 23 at the other end via the coupling elements 69.

[0091] The foot section 6 of the foot section 3 facing the head section 2 has a total of three slats, namely the slats 86, 76 and 82, as can be seen from the top view according to Fig. 14 results.

[0092] The slat 86 is firmly connected to the outer frame 23, for which purpose the outer frame 23 provides the holders 37 and 38, as can be seen in particular from the illustration according to Fig. 15 result.

[0093] The further slats 76 and 82 are arranged to be movable in relation to the outer frame 24, for which purpose the previously described U-profiles 36 are provided, which are arranged on the longitudinal beams 30 and 31 of the inner frame 24.

[0094] The movable slats 76 and 82 are in the Figures 20 and 21 or 22 and 23 are shown in detail.

[0095] As can be seen from a summary of the Figures 20 and 21The slat 76 is designed as a towing section 71 of the foot section 6. This towing section 71 has two spar pieces 74, which are connected to one another by means of a common cross spar 75. The slat 76, which is supported by the spar pieces 73, is provided opposite the cross spar 75.

[0096] On their mutually facing inner sides, the spar pieces 73 each have rollers 77 which, in the final assembled state, are inserted into the respective associated U-profiles 36.

[0097] On their underside, the spar pieces 73 each also carry driving pins 78.

[0098] The second movable slat 82 is in the Figures 22 and 23 It is designed as a trailing section 72 of the foot section 6.

[0099] The towing section 72 also has two spar sections 79 and 80, which are connected to each other by a common cross spar 81. On the upper side, the two spar sections 79 and 80 support the batten 82. Furthermore, each spar section 79 and 80 is equipped with rollers 83, which, in the final assembly, are accommodated by the corresponding U-profile 36.

[0100] The towing section 72 also has carrier tabs 84 mounted on the spar side, each of which provides a slot 85. In the final assembled state, a slot 35 provided by a carrier tab 84 is penetrated by a carrier pin 78 of the adjacent movable slat 76. In this way, the two displaceably mounted slats 76 and 82 are positively coupled to one another.

[0101] In the final assembled state, the movable slat 82 is arranged, as described above, with its cross member 81 between the driver pins 87 and 88 of the head section 2, so that a displacement movement of the head section 2 is transmitted to the movable slat 82. Since the slat 76 is positively coupled to the slat 82 in the manner described above, a head section movement results in the two slats 82 and 76 being moved along with it. Due to the distance between the head section-side driver pins 87 and 88 on the one hand, and due to the elongated hole design of the elongated hole 85 on the other, a delayed driver movement occurs between the head section 2 and the slat 82 or between the slat 82 and 76.

[0102] The functionality of the construction described above will now be explained in particular by means of a summary of the Figures 7 to 14 which show the slatted frame 1 according to the invention in four different positions.

[0103] The Figures 7 and8 show the slatted frame 1 according to the invention in its initial position. In this initial position, the headboard 2 is not pivoted and is located directly next to the footboard 3, i.e., the distance between the footboard section 6 of the footboard 3 and the headboard 2 is minimal.

[0104] The Figures 9 and 10 show a second position of the slatted frame 1 according to the invention. According to this position, the head part 2 is moved exclusively translationally in relation to the foot part 3, specifically away from it, so that a spacing is established between the head part 2 and the foot part 3. This spacing is in Fig. 9 marked with "A".

[0105] Based on the Figures 9 and 10 shown position of the head part 2, this can be returned to the position shown in the Figures 7 and 8shown position. This results in a translational back and forth movement of the head part 2 in relation to the foot part 3, whereby the foot part 3 or the foot part sections 6, 7 and 8 forming the foot part 3 remain unswivelled or unmoved.

[0106] For a transfer of the head part 2 from the Figures 7 and 8 shown position in the Figures 9 and 10 The drive device 63 is used in the position shown. This is supported on the one hand on the frame 22 and on the other hand on the carriage 56, so that when the carriage 56 moves in relation to the frame 22, the head part 2 carried by the carriage 56 is moved translationally.

[0107] The Figures 11 and 12reveal a third position of the head part 2. According to this position, the head part 2 is rotated relative to the foot part 3, specifically about the rotation axis 5. This rotational movement is accomplished by means of the drive device 55, which is arranged between the carriage 56 and the head part 2.

[0108] As a result of a twisting movement of the headboard 2, an angled transition is formed between the footboard 3 and the headboard 2, which leads to an unwanted crushing of a mattress supported by the slatted frame 1 in this area. To prevent this and to protect a mattress in this area, an automatic mattress compensation system is provided. This is achieved by the headboard 2 not only pivoting about the axis of rotation 5, but also moving translationally in the longitudinal direction 4, specifically away from the footboard 3. The distance of the translational movement of the headboard 2 depends on the twisting angle. The further the headboard 2 is pivoted in relation to the footboard 3, the further the headboard 2 is moved translationally away from the footboard 3. From a certain travel distance of the headboard 2, this leads to insufficient support of the buttocks by the mattress, since a gap that is too large arises between the headboard 2 and the footboard 3.To prevent this, the slats 82 and 76 of the foot section 6 move forward, namely by means of the previously described drag arrangement between the head section 2 and slat 82 on the one hand and slat 82 and slat 76 on the other hand.

[0109] Fig. 11 shows a position of the slatted frame 1, according to which the slat 82 adjacent to the headboard 2 has already moved forward, but the other slat 76 remains in its original position. In this position, a gap "B" forms between the footboard section 6 and the headboard 2.

[0110] The Figures 13 and 14show the slatted frame 1 in a fourth position, according to which the headboard 2 is fully upright, i.e. pivoted upwards as far as possible around the axis of rotation 5. In this position, the headboard 2 is not only twisted, but also moved away from the footboard 3 in a translational manner to such an extent that the second slat 76 is also dragged along in a translational manner and is at its maximum distance from the fixed slat 86, as shown in Fig. 14 shown. In this position, a gap dimension "C" results between head section 2 and foot section 6.

[0111] During a return movement of the head section 2 starting from the position in the Figures 13 and 14 shown position into the position shown in the Figures 7 and 8 In the position shown, the head part 2 is both turned back and moved back, as a result of which the movable slats 76 and 82 are also taken along until they again assume the positions shown in the Figures 7 and 8reach the position shown.
