Description

Technical area

[0001] The invention relates to an adjustable slatted frame and an adjustable reclining furniture. Background of the invention

[0002] A slatted frame typically serves as a base and / or support surface for a cushioned element such as a mattress, which can be used by a user for lying down and / or recreational purposes. Continuous improvement of the slatted frame is desirable, particularly with regard to sleeping comfort and ergonomics.

[0003] An adjustable slatted frame is particularly ergonomic for the user. Such a slatted frame can be adjusted either manually or automatically using a servomotor to adapt the slatted frame to the user's ergonomic needs. For example, the user can align the slatted frame flat or angle it completely or partially to customize it. In particular, it is known to adjust various sections or segments of the slatted frame in a targeted manner to achieve the greatest possible adaptation to the user's ergonomic needs.

[0004] However, the actuators required for the automatic adjustment of the slatted frame are large and bulky in order to enable the necessary forces for adjustment. The desire for ergonomic adjustability of the slatted frame and the space-saving arrangement of the actuator are at least partially conflicting objectives. Furthermore, the actuators are sometimes subjected to considerable stress, for example when a mattress lying on the frame and possibly even a user must be moved along with the slatted frame. Robust actuators are required that can withstand these demands for a long time. It is therefore the object of the present invention to provide an improved adjustable slatted frame that at least partially solves the above problem. Summary of the invention

[0005] The object is achieved according to the invention by an adjustable slatted frame according to claim 1. Advantageous developments of the invention are specified in the dependent claims.

[0006] According to the invention, the adjustable slatted frame comprises an outer frame and an inner frame fastened to the outer frame. The inner frame comprises an upper body section, a lower body section, and a drive section arranged between the upper body section and the lower body section, which drive sections together form a support surface for a cushioning element. On an underside of the drive section facing away from the support surface, at least one first adjusting device is arranged, which is force-transmittingly connected to at least one drive shaft fastened to the underside of the upper body and / or lower body section facing away from the support surface, such that the adjusting device is configured to pivot the upper body and / or lower body section from a flat position into at least one angled position by actuating the drive shaft.

[0007] The adjustable slatted frame advantageously allows for the adjustment device to be arranged in a space-saving manner by accommodating it below the support surface. Furthermore, the at least one drive shaft is directly coupled to the upper body and / or lower body section in a force-transmitting manner, allowing the adjustment device to interact effectively with the drive shaft in a confined space to pivot the upper body and / or lower body section from a flat position to at least one angled position. This ensures ergonomic adaptation to the user's needs, while also allowing the adjustment device and drive shaft to be accommodated in the slatted frame in the most space-saving manner possible.

[0008] A slatted frame is understood to be any device that serves as a base for at least one upholstered element, in particular a mattress, or another device for lying and / or sleeping on, such as a bed or other piece of furniture for resting or sleeping. In particular, a slatted frame is a component or assembly that can be arranged on a bed frame to accommodate such an upholstered element.

[0009] The slatted frame generally has an outer frame, which can be constructed in one piece or in multiple pieces from any material. The outer frame is preferably made of metal, plastic, wood, a composite material, or a combination of several of the aforementioned materials. The outer frame can be designed to border the slatted frame on all four sides, or it can consist of just two lateral components connected by connecting elements. The outer frame is essentially the component that provides the slatted frame with the necessary dimensional stability.

[0010] An adjustment device is generally understood to be a component or assembly capable of adjusting at least one pivotable part of the support surface relative to the outer frame or relative to the other part of the support surface, in particular, of varying the angle between two parts of the support surface. This can be either a purely mechanical device or an electrically adjustable device.

[0011] A flat position of the pivotable part of the support surface is understood to be the position in which this part of the support surface is arranged parallel to the outer frame and / or in a plane with the remaining part of the support surface. This flat position is the position in which the pivotable part of the support surface has the smallest possible adjustment angle, usually of approximately 0°, relative to the outer frame or the remaining support surface. In the flat position, the entire support surface can be arranged flat. Furthermore, a flat position of the upper body section refers to the fact that the upper body section is arranged flat, for example in relation to the drive section and / or the outer frame. Likewise, a flat position of the lower body section refers to the fact that the lower body section is arranged flat, for example in relation to the drive section and / or the outer frame.

[0012] In contrast, the angled position is essentially a position of the pivotable part of the support surface that is characterized by an angle that differs from the adjustment angle of the flat position. In particular, the angled position is understood to mean the position of the maximum possible adjustment of the pivotable part of the support surface relative to the outer frame by means of the adjustment device. In principle, angles of the adjustable part of the support surface relative to the outer frame of up to 90° are conceivable, and in some special applications even beyond that. An angled position of the upper body section can therefore refer to the upper body section being arranged at an angle, for example in relation to the drive section and / or the outer frame.Likewise, an angled position of the lower body portion may refer to the lower body portion being arranged at an angle, for example with respect to the drive portion and / or the outer frame.

[0013] The pivoting of the upper body and / or lower body sections occurs in particular with respect to the drive section and / or the outer frame. The drive section and / or the outer frame are not moved by the adjustment device, but remain stationary, for example, with respect to a base and / or a bed frame. In particular, the drive section and the outer frame remain stationary relative to one another during the movement, while the upper body and / or lower body sections are moved relative to the drive section and / or the outer frame.

[0014] According to one embodiment, the at least one drive shaft is arranged parallel to a central transverse axis of the inner frame. The central transverse axis runs, for example, between the two long sides of the outer frame and in particular in the middle of the overall length of the outer frame. It is aligned, for example, parallel to the end faces at the head and foot ends of the slatted frame. This arrangement allows the drive shaft to exert particularly efficient force on the upper and lower body sections.

[0015] According to one embodiment, the at least one drive shaft has a telescopic mechanism configured to retract and extend the drive shaft along a rotational axis of the drive shaft. Due to the telescopic mechanism, the drive shaft can be adjusted lengthwise along its rotational axis, allowing the drive shaft to be adapted to the respective internal frame.

[0016] According to one embodiment, the drive shaft is connected to the upper body and / or lower body section in a force-transmitting and / or rotationally fixed manner. In other words, the upper body and / or lower body section is pivotable or driven directly by the drive shaft. This ensures particularly efficient power transmission.

[0017] According to one embodiment, the upper body and / or lower body section has two parallel outer struts that are connected by means of several spring bars and / or at least one cross strut. The drive shaft is connected to the two outer struts in a force-transmitting and / or rotationally fixed manner. Due to the above design, the upper body and / or lower body section is particularly dimensionally stable and torsionally rigid. This allows for particularly efficient power transmission to these components.

[0018] According to one embodiment, the upper body section has a head section and a back section connected to the head section via a hinge. The back section is arranged between the head section and the drive section. The back section has two parallel outer struts that are connected by means of several spring strips and / or at least one cross strut. The drive shaft is connected to the two outer struts of the back section in a force-transmitting manner. By providing a head section and a back section, the upper body section can be more finely divided, allowing it to be better adapted to the ergonomic needs of the user.In addition, the drive shaft is only connected to the back section in a force-transmitting manner, so that the back section is directly and actively driven by the drive shaft, whereas the head section can only be adjusted passively, namely due to the relative movement of the back section.

[0019] To achieve this, the head section can be connected to the outer frame via a rigid support element. The support element can be mounted so as to be rotatable relative to both the head section and the outer frame. In particular, the support element is designed to convert or redirect the movement of the upper body section from a flat position to at least one angled position into a movement of the head section from a flat position relative to the back section to at least one angled position relative to the back section, and vice versa. The movement of the head section relative to the back section is therefore driven purely passively by the movement of the upper body section relative to the drive section, so that both movements can take place using a single adjustment device. This applies to both a movement into the flat and a movement into the angled position.

[0020] According to one embodiment, the lower body section has a leg section and a foot section connected to the leg section via a hinge. The leg section is arranged between the foot section and the drive section. The leg section has two parallel outer struts that are connected by means of several spring strips and / or at least one cross strut. The drive shaft is connected to the two outer struts of the leg section in a force-transmitting manner. The leg section and the foot section can also be used to divide the lower body section into further areas or sections, so that it can also be better adapted to the ergonomic needs of the user. Furthermore, only one of the two sections is directly driven via the drive shaft, whereas the foot section is only passively driven due to the relative movement of the leg section.

[0021] To achieve this, the foot section can be connected to the outer frame via a rigid support element. The support element can be mounted so as to be rotatable relative to both the foot section and the outer frame. In particular, the support element is designed to convert or redirect the movement of the lower body section from a flat position to at least one angled position into a movement of the foot section from a flat position relative to the leg section to at least one angled position relative to the leg section, and vice versa. The movement of the foot section relative to the leg section is therefore driven purely passively by the movement of the lower body section relative to the drive section, so that both movements can take place using a single adjustment device. This applies to both a movement into the flat and a movement into the angled position.

[0022] According to one embodiment, an additional second drive shaft is provided in addition to the at least one first drive shaft. In other words, a second drive shaft is provided in addition to the at least one first drive shaft. The first drive shaft is arranged on an underside of the upper body section facing away from the support surface and is connected to it in a force-transmitting manner. The second drive shaft is arranged on an underside of the lower body section facing away from the support surface and is connected to it in a force-transmitting manner. In addition to the first adjusting device, an additional second adjusting device is arranged on a side of the drive section facing away from the support surface. In other words, in addition to the first adjusting device, a second adjusting device is arranged on the underside of the drive section facing away from the support surface.The first adjustment device is connected to the second drive shaft and the second adjustment device is connected to the first drive shaft in a force-transmitting manner, so that the two drive shafts can be operated independently of one another. The first drive shaft can therefore be rotated by the second adjustment device, and the second drive shaft can be rotated by the first adjustment device. This offers the advantage that the upper body section and the lower body section can be adjusted independently of one another to the ergonomic needs of the user. In addition, two adjustment devices can be accommodated in a space-saving manner on the underside of the drive section, facing away from the support surface. By using two adjustment devices, each of them can be made smaller and less expensive, since one adjustment device only has to adjust the upper or lower body section. This facilitates the space-saving arrangement.Furthermore, the power requirement of each individual adjustment device does not increase when the upper and lower body sections are adjusted simultaneously.

[0023] According to one embodiment, the first and second drive shafts run parallel to each other and are each arranged transversely to a longitudinal axis of the inner frame. The longitudinal axis of the inner frame runs between the head and foot ends of the slatted frame. It is arranged, in particular, perpendicular to the end faces at the head and foot ends of the slatted frame. This allows for a particularly efficient flow of force from the first and second drive shafts to the inner frame.

[0024] According to one embodiment, the first drive shaft is arranged at an end of the upper body section facing the drive section and / or the second drive shaft is arranged at an end of the lower body section facing the drive section. Due to the above arrangement, the first and second drive shafts can be accommodated on the inner frame in a particularly space-saving manner and are also located in close proximity to the drive section, on which the first and second adjustment devices are arranged. This enables particularly efficient power transmission from the first and second adjustment devices to the first and second drive shafts.

[0025] According to one embodiment, the first and second drive shafts spatially delimit the drive section in the longitudinal direction of the inner frame and / or are arranged outside the drive section. In other words, the drive section is arranged between the first and second drive shafts. In this way, a particularly efficient power flow from the drive section to the first and second drive shafts can occur.

[0026] According to one embodiment, the first and second drive shafts define a receiving area between them, in which the first and second adjusting devices are arranged. In other words, the first and second adjusting devices are arranged between the first or second drive shaft, whereby they can be arranged on the inner frame in a particularly space-saving manner. Because the drive shafts can be arranged outside the drive section, more installation space can be available in the drive section for the actuators, in particular the linear actuators described in more detail below. These can be made correspondingly stronger thanks to the additional installation space in order to meet the demands of adjusting the slatted frame.

[0027] According to one embodiment, the first adjusting device comprises a first linear actuator and the second adjusting device comprises a second linear actuator. The first and second linear actuators are each configured to perform a linear movement in the longitudinal direction of the inner frame and transversely to the drive shafts. The longitudinal direction of the inner frame runs, in particular, parallel to the longitudinal axis of the inner frame. In simple terms, each adjusting device has a linear actuator that can perform a linear movement toward or away from the respective first and / or second drive shaft. In other words, the linear movement takes place between the first and second drive shafts.

[0028] According to one embodiment, the drive section has two parallel outer struts that are connected by means of several spring strips and / or at least one cross strut. This ensures a particularly stable construction of the drive section.

[0029] According to one embodiment, the first and / or second adjusting device has a height perpendicular to the support surface that is less than 90%, preferably less than 80%, particularly preferably less than 70% of a height of the outer struts perpendicular to the support surface. This allows the first and second adjusting devices to be accommodated in a particularly space-saving manner. The height of the adjusting device here refers in particular to a height of the respective linear actuator, for example the maximum height of the respective linear actuator. In the event that the linear actuator comprises a housing, the height of the respective linear actuator refers in particular to the height, for example the maximum height, of the housing.

[0030] According to one embodiment, the first linear actuator has a first and a second end. The first end is rotatable on the first drive shaft and the second end is mounted on the second drive shaft in a rotationally fixed manner. The first end is connected in a force-transmitting manner to a first tension element which extends from the first end in the direction of the second drive shaft and is connected thereto in a rotationally fixed manner. The second linear actuator has a first and a second end. The first end is rotatable on the second drive shaft and the second end is mounted on the first drive shaft in a rotationally fixed manner. The first end is connected in a force-transmitting manner to a second tension element which extends from the first end in the direction of the first drive shaft and is connected thereto in a rotationally fixed manner. The above design ensures particularly efficient power transmission from the linear actuators to the drive shafts.Furthermore, the above design features a lever effect, allowing the drive shaft to be driven with minimal force. Furthermore, the pulley principle can be utilized to enable the largest possible rotational movement—in this case, a rotational movement of the drive shaft—with a short linear actuation path. Furthermore, the above design offers a particularly space-saving arrangement, as the actuator and the respective tension element are arranged next to each other, perpendicular to the direction of the linear movement.

[0031] A rotationally fixed connection between one end of a linear actuator and a drive shaft means in this case that the end is attached to the outer circumference of the drive shaft, for example directly or via a lever arm or a sleeve. In particular, the attachment point of the end of the linear actuator and / or the lever arm and / or the sleeve is rigidly connected to the drive shaft, i.e., rotationally fixed or non-rotatably connected. An extension or shortening of the linear actuator can therefore cause a torque on the drive shaft and rotate the drive shaft. A rotatable connection between one end of a linear actuator and a drive shaft means in this case that the end and / or another component, for example a sleeve as described in more detail below, at least partially surrounds the drive shaft, but is mounted on the drive shaft in a sliding and / or rotating manner.In other words, extending or shortening the linear actuator cannot cause any torque on the drive shaft, nor can it rotate the drive shaft. However, the linear actuator can be supported by the rotatable connection to the drive shaft, particularly against a movement in the longitudinal direction of the inner frame, for example, when the linear actuator is extended or shortened.

[0032] According to one embodiment, the first tension element is welded, pressed, or riveted to the second drive shaft. The second tension element is welded, pressed, or riveted to the first drive shaft. This ensures a particularly reliable, rotationally fixed connection between the respective tension element and the respective drive shaft.

[0033] According to one embodiment, the first and / or second tension element is a longitudinal strut, in particular a double longitudinal strut. This is a particularly stable embodiment of the tension element for absorbing the forces of the respective linear actuator and transmitting them to the drive shaft.

[0034] The double longitudinal strut can comprise two longitudinal struts. These can run parallel to each other on two opposite sides of the drive shafts and can each be mounted on two opposite sides of the drive shafts. For example, one longitudinal strut can run above and one longitudinal strut below the respective drive shaft and can also be mounted on it, for example via lever arms, which in turn can be arranged on a sleeve that at least partially encloses the drive shaft. Designing the tension elements as such double longitudinal struts prevents unwanted rotation of the drive shafts when the linear actuators are lengthened or shortened.

[0035] According to one embodiment, the first end of the first linear actuator and the first end of the second linear actuator can each be arranged on a telescopic arm that can be adjusted by the respective linear actuator. Adjusting the telescopic arm can cause the first ends to move in the direction of the first or second drive shaft. In other words, the first end of the first linear actuator and the first end of the second linear actuator can be moved in the direction of the first and second drive shafts by means of a telescopic arm. The telescopic arm offers a particularly space-saving option for implementing a linear movement between the first drive shaft and the second drive shaft.

[0036] According to one embodiment, the first end of the first linear actuator is rotatably mounted on the first drive shaft by means of a first sleeve, and the second end of the first linear actuator is non-rotatably mounted or supported on the second drive shaft by means of a second sleeve, for example via a gripper arm. The first end of the second linear actuator is rotatably mounted on the second drive shaft by means of a first sleeve, and the second end of the second linear actuator is non-rotatably mounted or supported on the first drive shaft by means of a second sleeve, for example via a gripper arm. The sleeve makes it easy to mount the first end freely rotating with the drive shaft. In this sense, the sleeve can also be understood as a bearing. For example, a gripper arm can easily follow the linear movement of the telescopic arm and at the same time support the linear actuator on the drive shaft.Thus, the linear actuator is suspended or mounted at each end on one of the two drive shafts. This represents a particularly space-saving option for arranging the respective linear actuator in the internal frame.

[0037] Each linear actuator can be connected to the drive shaft with one sleeve per drive shaft. In other words, two sleeves are provided for both the first linear actuator and the second linear actuator, one sleeve per drive shaft.

[0038] According to one embodiment, the first end of the first linear actuator is connected to the first tension element in a force-transmitting manner by means of the first sleeve, in particular to a tension hook. The first end of the second linear actuator is connected to the second tension element in a force-transmitting manner by means of the first sleeve, in particular to a tension hook. In other words, the sleeve establishes the force-transmitting connection between the first end of the respective linear actuator and the respective tension element. The sleeve can be freely rotated around the drive shaft, since the telescopic arm engages in the sleeve or is connected to it by means of the tension hook, and the sleeve rotates about the rotational axis of the drive shaft through a linear movement of the tension hook. The respective tension hooks can be designed to be rotatable about their attachment point on the first sleeve.In this way, secondary movements during the length adjustment of the linear actuator can be compensated, preventing additional, unwanted forces from acting on the drive shafts. A draw hook also represents a technically simple component for converting linear movement into rotational movement. For example, the draw hook can be detachably connected to the first end of the telescopic arm using a connecting element, such as a rivet or bolt, making the draw hook replaceable.

[0039] According to one embodiment, the second end of the first linear actuator and / or the second end of the second linear actuator is connected to the second sleeve by means of a gripper arm, wherein the gripper arm is rotatably mounted relative to the second sleeve. This allows the respective linear actuator to rotate relative to the respective sleeve, so that secondary movements during the length adjustment of the linear actuator can be compensated. In other words, the gripper arm of the first linear actuator has a folding mechanism that is configured to unfold as a result of a linear movement of the first linear actuator in the direction of the first drive shaft and to fold as a result of a linear movement of the first linear actuator in the direction of the second drive shaft.The gripper arm of the second linear actuator has a folding mechanism that is designed to open up as a result of a linear movement of the linear actuator in the direction of the second drive shaft at its first end and to fold in as a result of a linear movement of the first linear actuator in the direction of the first drive shaft. In other words, the folding mechanism allows the linear actuator to compensate for or follow the linear movement of the telescopic arm by opening the gripper arm, thus preventing the two drive shafts from being pulled towards each other. This prevents undesired bending of the drive shafts. In this way, the gripper arm can be supported on one drive shaft, while the other end, in the form of the telescopic arm, can perform a pulling movement.

[0040] The first and / or second tension element is particularly rigid. The tension elements therefore form a rigid connection between the first sleeve and the second sleeve. For example, the tension elements can be metal struts. The tension elements therefore transmit tensile and compressive forces between the two sleeves.

[0041] According to one embodiment, the first adjusting device is configured to trigger a rotation of the second drive shaft, in particular relative to the first drive shaft, as a result of actuation of the first linear actuator, such that the lower body section can be pivoted from a flat position into at least one angled position. Additionally or alternatively, the second adjusting device can be configured to trigger a rotation of the first drive shaft, in particular relative to the second drive shaft, as a result of actuation of the second linear actuator, such that the upper body section can be pivoted from a flat position into at least one angled position. The linear actuators can be designed to enable continuous adjustment. This, in turn, enables continuous pivoting of the upper body and / or lower body section into any position between the flat and the angled position.In this way, the upper body and / or lower body section can be moved from a flat position to at least one angled position with particularly efficient force application. In particular, due to the continuous movement of the linear actuator, it can be moved continuously between a flat position and an angled position.

[0042] The first adjustment device, in particular the first linear actuator, and the second adjustment device, in particular the second linear actuator, can be arranged at a distance from one another along the two drive shafts. Viewed in the longitudinal direction of the inner frame, the adjustment devices, in particular the linear actuators, are therefore arranged at the same height. This results in a particularly space-saving arrangement.

[0043] In particular, it can be provided that the first adjustment device and the second adjustment device are of identical design and arranged mirror-symmetrically with respect to a longitudinal plane and a transverse plane of the slatted frame on the two drive shafts. In particular, the adjustment devices, in particular the linear actuators, are structurally identical parts. These can be rotated, for example, by 180°, when used. The desired functionality is achieved through the respective connections to the drive shafts, as described herein. The use of structurally identical elements, in turn, reduces manufacturing costs and simplifies assembly.

[0044] In particular, all features explained herein can apply to both adjustment devices or linear actuators. The drive shafts can also be designed identically, so that all features explained herein can apply to both drive shafts.

[0045] According to one embodiment, the adjusting device further comprises a control unit configured to actuate the adjusting device. The control unit may, for example, comprise a computer unit connected to a servomotor of the adjusting device in a signal-transmitting manner in order to control the servomotor and thus trigger actuation of the adjusting device. The servomotor may, for example, be coupled to a drive mechanism that interacts with the telescopic arm to enable a linear movement. The drive mechanism may, for example, be a spindle drive.

[0046] The first adjustment device and the second adjustment device can be configured to be independently activatable. For example, the controller can activate and / or deactivate the two adjustment devices independently of each other. Preferably, a single controller is provided for both adjustment devices. Also, preferably, a single power supply is provided for both adjustment devices.

[0047] According to one embodiment, the control unit is connected to an operating element for signal transmission, via which the control unit can be controlled. An operating element enables particularly user-friendly input of control commands to the control unit. In this respect, the operating element represents an interface for receiving control commands and transmitting them to the control unit.

[0048] According to one embodiment, the operating element is a remote control that is connected to the control unit wirelessly or via a cable to transmit signals. A remote control represents a particularly convenient way for a user to control the control unit wirelessly or via a cable. The remote control can, for example, have various input buttons assigned to different control commands. For example, the remote control can have an operating function for the adjustable lower body section, an operating function for the adjustable upper body section, and an operating function for adjusting the upper body and lower body sections simultaneously.

[0049] According to one embodiment, the adjustment device is at least partially waterproof. This embodiment is particularly advantageous when the adjustable slatted frame is used outdoors.

[0050] According to one embodiment, the adjustment device comprises at least one housing in which the linear actuator is housed, preferably completely enclosed. Due to the particularly complete housing of the adjustment device, the adjustment device is protected from environmental influences, such as moisture and / or dust, which further increases the longevity of the adjustment device. In particular, the housing can be a case, so that the adjustment device can be easily disassembled and assembled and can be transported more easily between disassembly and assembly.

[0051] According to one embodiment, the housing has at least one opening in which the drive shaft is mounted. In other words, the drive shaft is at least partially guided within the housing. In particular, due to the telescopic mechanism of the drive shaft, it can be fully retracted into the housing, allowing the adjustment device, including the drive shaft, to be easily disassembled and assembled without having to transport the various components individually.

[0052] According to one embodiment, an energy storage device is further provided, which is designed to at least partially supply the adjusting device with electrical energy. An energy storage device is particularly advantageous if the adjusting device is an electrical adjusting device, which is preferred. The adjusting device can therefore be operated solely from the energy storage device. In addition, the adjusting device has a mains connection, for example a power cable and / or a power pack, via which the adjusting device can be supplied with electrical energy from the power grid. Both the energy storage device and the mains connection can be provided. In this way, the adjusting device can normally be operated from the mains without requiring maintenance.In the event of a power failure, however, the adjustment device can continue to operate from the energy storage device, at least for a short time, in order to prevent, for example, bedridden people from being trapped in uncomfortable positions.

[0053] The invention further provides an adjustable reclining furniture item comprising at least one adjustable slatted frame according to one of the preceding embodiments and at least one cushioning element arranged on the support surface of the adjustable slatted frame, in particular wherein the cushioning element is a mattress. The same features, effects, and advantages apply as already mentioned for the adjustable slatted frame.

[0054] Further features, advantages and possible applications of the invention will become apparent from the following description of the embodiments and figures. Short character description

Detailed description of embodiments

[0056] Fig. 1 shows an adjustable slatted frame 10 in an angled position.

[0057] The adjustable slatted frame 10 has an outer frame 12 with a rectangular basic shape.

[0058] In particular, the outer frame 12 comprises two mutually parallel longitudinal beams 14 and two mutually parallel transverse beams 16, which respectively connect the end faces of the longitudinal beams 14 to form a rectangular outer frame 12. As shown in Fig. 1, the two cross beams 16 and the two longitudinal beams 14 are aligned at a 90° angle to each other.

[0059] In addition, the adjustable slatted frame 10 has an inner frame 18 which is attached to the outer frame 12.

[0060] As in Fig. 1 and also in Fig. 3, the inner frame 18 has different sections. Specifically, the inner frame 18 has, along the longitudinal direction L R of the adjustable slatted frame 10 has an upper body section 20, a lower body section 22 and a drive section 24 arranged between the upper body section 20 and the lower body section 22.

[0061] Basically, the upper body section 20, the lower body section 22 and the drive section 24 have a common upper side 26 and a common lower side 28 opposite the upper side.

[0062] The upper sides 26 of the upper body section 20, the lower body section 22 and the drive section 24 define a common support surface 30 for a cushioning element, for example a mattress.

[0063] Specifically, the upper body section 20 can be divided into a head section 32 and a back section 34. The back section 34 is arranged between the head section 32 and the drive section 24.

[0064] Furthermore, the lower body portion 22 can be divided into a leg portion 36 and a foot portion 38, wherein the leg portion 36 is arranged between the foot portion 38 and the drive portion 24.

[0065] Consequently, as in Fig. 3, the inner frame 18 is divided into five sections arranged one behind the other, namely a foot section 38, a leg section 36, a drive section 24, a back section 34 and a head section 32.

[0066] Each of the above-mentioned sections represents a single segment of the inner frame 18 and is configured, as the name of the section suggests, to support a body part of a user.

[0067] The structure of the back section 34 is explained below as an example, which is representative of the other sections.

[0068] The back section 34 has two mutually parallel outer struts 40 which are parallel to the longitudinal direction L R of the slatted frame 10.

[0069] The two outer struts 40 running parallel to each other are connected to each other via several spring strips 42 and at least one cross strut 44.

[0070] The spring strips 42 form the support surface 30 for a cushioning element arranged on the upper side 26. In particular, the spring strips 42 are interchangeably connected to the outer struts 40. For example, the spring strips 42 can each be releasably connected to the outer struts 40 at their free ends via a locking element 46.

[0071] To enable an adjustable slatted frame 10, the upper body section 20, the lower body section 22, and the drive section 24 are connected to each other via several hinges 48. Thanks to the hinges 48, the upper sections can be pivoted relative to each other or relative to the outer frame 12.

[0072] Furthermore, the head section 32 is connected to the outer frame 12, more precisely to the longitudinal beam 14, via at least one support element 50. Furthermore, at least one foot section 38 is connected to the outer frame 12, more precisely to the longitudinal beam 14, via at least one support element 50.

[0073] The support element 50 is connected to the head section 32 and the foot section 38, as well as to the outer frame 12, in such a way that when the back section 34 or the leg section 36 is raised, the respective section angles relative to these sections 34, 36. The specific mechanism of the adjustable slatted frame is explained in more detail below.

[0074] Furthermore, the inner frame 18 has at least one adjusting device 52 arranged on an underside 28 of the drive section 24 facing away from the support surface 30. In other words, the first adjusting device 52 is arranged on the underside 28 of the drive section 24.

[0075] Furthermore, the inner frame 18 has a second adjusting device 54, which is also arranged on an underside 28 of the drive section 24 facing away from the support surface 30. Specifically, the second adjusting device 54 is arranged analogously to the first adjusting device 52 on the underside 28 of the inner frame 18. This is shown in Fig. 4 can be recognized.

[0076] Furthermore, the inner frame 18 has a first drive shaft 56 and a second drive shaft 58.

[0077] Specifically, the first drive shaft 56 is arranged on a side of the back section 34 facing away from the support surface 30 and is connected to it in a force-transmitting manner.

[0078] In addition, the second drive shaft 58 is arranged on a side of the leg section 36 facing away from the support surface 30 and is connected to it in a force-transmitting manner.

[0079] In other words, the first drive shaft 56 and the second drive shaft 58 are transverse to the longitudinal axis L R of the slatted frame 10 and parallel to the central transverse axis M Q of the slatted frame 10. In particular, the first drive shaft 56 and the second drive shaft 58 are aligned parallel to each other.

[0080] Both the first drive shaft 56 and the second drive shaft 58 each have a telescopic mechanism 60 that retracts or extends the respective drive shaft 56, 58 along its rotational axis. This allows for length adjustments.

[0081] The first drive shaft 56 is connected to the back section 34 in a force-transmitting manner. Specifically, the two parallel outer struts 40 of the back section 34 each have a recess 62 into which the first drive shaft 56 engages.

[0082] Furthermore, a recess 62 is also provided on each of the two outer struts 40 of the leg section 36, which run parallel to one another, into which the second drive shaft 58 engages.

[0083] In particular, the first drive shaft 56 and the second drive shaft 58 are captively and rotatably mounted in the recesses 62.

[0084] A setting-up mechanism 64 is assigned to each of the recesses 62 on both sides of the slatted frame 10, which setting-up mechanism comprises a pivotable hinge that connects the drive section 24 to the back section 34 and the drive section 24 to the leg section 36 in a force-transmitting manner.

[0085] In this respect, the back section 34 and the leg section 36 are actively driven by the drive shafts 56, 58, whereas the head section 32 and the foot section 38 can be passively set up or pivoted into an angled position via the setting elements 50.

[0086] In other words, the first drive shaft 56 is arranged at an end of the upper body section 20 facing the drive section 24 and the second drive shaft 58 is arranged at an end of the leg section 36 or the lower body section 22 facing the drive section 24.

[0087] As in Fig. As can be seen in Figure 4, the first drive shaft 56 and the second drive shaft 58 define a receiving area 66 in which the first adjusting device 52 and the second adjusting device 54 are arranged. In other words, the first adjusting device 52 and the second adjusting device 54 are arranged between the first drive shaft 56 and the second drive shaft 58.

[0088] As in the Fig. 6A and Fig. As shown in Figure 6B, the first adjustment device 52 has a first linear actuator 68, and the second adjustment device 54 has a second linear actuator 70. The linear actuators 68, 70 can be, for example, spindle drives or rack and pinion drives. They can include an electric motor 82 that drives the linear adjustment of the linear actuators 68, 70.

[0089] Specifically, the first adjusting device 52 is connected to the second drive shaft 58 and the second adjusting device 54 is connected to the first drive shaft 56 in a force-transmitting manner, so that the two drive shafts 56, 58 can be actuated independently of one another by the linear actuator 68 and the linear actuator 70.

[0090] As in the Fig. 5A to 5C, the first linear actuator 68 has a first end 72 and a second end 74, wherein the first end 72 is rotatably mounted on the first drive shaft 56 and the second end 74 is non-rotatably mounted on the second drive shaft 58. In other words, the first end 72 and the second end 74 are arranged opposite one another.

[0091] The first end 72 is connected to a first tension element 76 in a force-transmitting manner, which extends from the first end 72 toward the second drive shaft 58. The first tension element 76 is connected to the second drive shaft 58 in a rotationally fixed manner.

[0092] Furthermore, the second linear actuator 70 also has a first end 72 and a second end 74, wherein the first end 72 is rotatably mounted on the second drive shaft 58 and the second end 74 is non-rotatably mounted on the first drive shaft 56. The first end 72 is force-transmittingly connected to a second tension element 78, which extends from the first end 72 toward the first drive shaft 56. The second tension element 78 is non-rotatably connected to the first drive shaft 56.

[0093] For example, the first tension element 76 can be welded, pressed or riveted to the second drive shaft 58, for example via a sleeve 85.

[0094] The second tension element 78 can be welded, pressed or riveted to the first drive shaft 56, for example via a sleeve 85. As a result, the second tension element 78 is connected to the first drive shaft 56 in a rotationally fixed manner and the first tension element 76 is connected to the second drive shaft 58 in a rotationally fixed manner.

[0095] In particular, the first and / or the second tension element 76, 78 can be a longitudinal strut, in particular a double longitudinal strut.

[0096] More specifically, the first linear actuator 68 and the second linear actuator 70 each have a telescopic arm 80 at the first end 72 such that the first end 72 of the first linear actuator 68 is movable toward the first drive shaft 56 and back, and the first end 72 of the second linear actuator 70 is movable toward the second drive shaft 58 and back.

[0097] The first end 72 of the first linear actuator 68 is rotatably mounted on the first drive shaft 56 by means of a sleeve 84. The sleeve 84 can also be considered a bearing. Furthermore, the first end 72 of the second linear actuator 70 is rotatably mounted on the second drive shaft 58 by means of a sleeve 84.

[0098] In particular, the first end 72 of the first linear actuator 68 is connected to the first tension element 76 by means of the sleeve 84 in a force-transmitting manner. For this purpose, the first end 72 has a tension hook 86, which connects the telescopic arm 80 to the sleeve 84 in a force-transmitting manner. In particular, a locking element 80 is provided on the sleeve 84 between the first tension element 76 and the tension hook 86, which connects the tension hook 86 and the sleeve 84 to one another in a force-transmitting manner. The same structure applies analogously to the second linear actuator 70, which, in comparison to the first linear actuator 68, is arranged with respect to the longitudinal axis L Rof the slatted frame 10 is arranged point-symmetrically. This is shown in the Fig. 6A and Fig. 6B can be seen.

[0099] Furthermore, the second end 74 of the first linear actuator 68 is non-rotatably mounted on the second drive shaft 58, for example via a gripper arm 90. In addition, the second end 74 of the second linear actuator 70 is non-rotatably mounted on the first drive shaft 56, for example via a gripper arm 90.

[0100] The gripping arm 90 of the first and second linear actuators 68, 70 each has a guide element 92 (see Fig. 5A) which extends opposite to the telescopic arm 80 and has a folding mechanism 94 at the free end. The folding mechanism 94 has a pincer-shaped element 96 which engages the second drive shaft 58.

[0101] The folding mechanism 94 of the first linear actuator 70 is configured to unfold as a result of a linear movement of the linear actuator 70 in the direction of the first drive shaft 58 and to fold as a result of a linear movement of the first linear actuator 68 in the direction of the second drive shaft 58. The folding mechanism 94 of the second linear actuator 72 functions accordingly.

[0102] Consequently, the first adjustment device 52 and the second adjustment device 54 are configured to trigger a rotation of the first and second drive shafts 56, 58 as a result of an actuation of the first and second linear actuators 68, 70, so that the back section 34 and the leg section 36 can be moved from a flat position, as shown in Fig. 2, can be pivoted into at least one angled position, as in Fig. 1 is shown.

[0103] In addition, in the Fig. 5A-5C show an exemplary setup process using the first linear actuator 68. In particular, the force flow K F starting from the first linear actuator 68 to the second drive shaft 58 is shown by means of arrows as well as the resulting rotational movement of the second drive shaft 58.

[0104] In a first step, the telescopic arm 80 moves in the direction of the second drive shaft 58. As a result of this linear movement, a force is transmitted from the telescopic arm 80 to the connected draw hook 86, which is connected to the sleeve 84 in a force-transmitting manner, which is freely rotatably mounted on the first drive shaft 56, so that no force is transmitted from the first linear actuator 68 to the first drive shaft 56. On the other hand, as shown in perspective in Fig. 5A, the sleeve 84 is rotated counterclockwise so that the first tension element 76 coupled to a locking element 88 via the sleeve 84 moves linearly to the left.

[0105] Since the first tension element 76 is connected to the second drive shaft 58 via a fastening point 79 in a rotationally fixed manner, the second drive shaft 58 rotates counterclockwise.

[0106] Since a mirror-inverted second linear actuator 70 (not shown due to the perspective) is connected to the first drive shaft 56 in a force-transmitting manner, a rotational movement of the first drive shaft 56 also takes place in a clockwise direction.

[0107] As a result of the rotational movements of the first drive shaft 56 and the second drive shaft 58, force is transmitted to a setting mechanism 64 which is connected to the drive shafts 56, 58 in a force-transmitting manner and which transmits the force from the drive shafts 56, 58 to the respective back section 64 and the leg section 36 and pivots them into an angled position.

[0108] In other words, the back section 34 and the leg section 36 are actively or directly driven by the first adjusting device 52 and the second adjusting device 54.

[0109] In contrast, the head section 32 and the foot section 38 are only passively driven, as they are connected to the actively driven back section 34 and the leg section 36 by hinges 48. These elements are set up using the above-described setting elements 50, which connect the respective sections to the outer frame 12.

[0110] The described sequences refer to a movement from a flat position to an angled position. For the reverse movement, the sequences are also reversed.

[0111] Furthermore, the adjustable slatted frame 10, as shown in the Fig. 6A and Fig. 6B, a control unit 98 which is configured to actuate the adjusting devices 52 and 54, respectively.

[0112] In addition, the control unit 98 has an operating element 100, which is connected to the control unit 98 for signal transmission. For example, the operating element 100 can be as in Fig. 7, the control element 100 can be a remote control that is connected to the control unit 98 wirelessly, for example via Bluetooth or WiFi. Alternatively, the control element 100 can also be connected to the control unit 98 via a cable.

[0113] Furthermore, the first adjustment device 52 and the second adjustment device 54 each have a housing 102 that encloses them in a watertight manner. The housing 102 can have an opening 104 in which the first drive shaft 56 and the second drive shaft 58 are rotatably mounted.
