Description

[0001] Prior art reveals slatted bed bases with a surrounding frame to which numerous slats are attached. Such bed bases can feature a reinforced lumbar support area. This reinforcement is achieved by placing an additional slat on top of each existing slat in this area and connecting it to the existing slat via a sliding mechanism. Moving the sliding mechanism allows adjustment of the firmness of the stacked pair of slats. The slats cannot be adjusted vertically relative to the support surface. Adjusting the sliding mechanism is manual and therefore time-consuming, as the bed base must first be exposed and the sliding mechanism manually moved to the desired position. A mattress is then placed on the bed base, and the user checks the firmness setting by lying on the mattress.If the firmness level is not optimally set, the procedure must be repeated until a comfortable firmness is set for that user.

[0002] The object of the invention is to provide a slatted bed base with lumbar support in which the lumbar support can be easily and individually adjusted to suit different users. Furthermore, the lumbar support should preferably be retrofittable and easily accessible for repairs, for reasons of sustainability.

[0003] To solve the problem, the invention proposes a slatted frame with a lumbar support according to claim 1.

[0004] In order to be able to adjust the lumbar support in a simple way, for example even when the user is in a lying or sitting position on a mattress placed on the slatted frame, the slatted frame has a preferably electrically adjustable lumbar support.

[0005] The lumbar support comprises a slat package which is adjustable relative to a frame of the slatted base, whereby in the basic position the slat package lies in a common plane with the slats fixed to the slatted base and can be adjusted to a support position via a motor-driven knee lever system, in which the slat package is raised and protrudes in front of the slat plane.

[0006] The adjustment to the support position is achieved via a toggle lever system, which is connected on one side to the slat package and on the other side to a preferably electrically driven actuator, whereby different support positions can be continuously adjusted.

[0007] The toggle lever system comprises a first adjusting lever and a first steering lever, which guides the adjusting lever in the desired direction during its adjustment. The first adjusting lever is longitudinally guided at one end in a second fitting on a second frame part and connected to a plunger of the actuator. Longitudinally guided means in the direction of the slatted frame's length, perpendicular to the slats.

[0008] The slat assembly is attached to the first set of fittings, which are held by an adjusting rod running parallel to the slats. The second end of the first adjusting lever is also connected to this rod. The first steering lever of the toggle lever system is rotatably attached at one end to the second frame part and pivotally connected at the other end to the adjusting lever. In the neutral position, the levers are extended, oriented approximately parallel to the plane of the slatted frame. When the actuator is engaged, the plunger pushes the first end of the adjusting lever longitudinally, causing the adjusting lever to straighten via the pivoting steering lever.The second end of the adjusting lever is adjusted approximately vertically to the slat plane, and the adjusting rod connected to this end lifts the slat package, which is integrated into the slatted frame and adjustable relative to it, out of the plane into a support position that can be selected and adjusted by the user.

[0009] To ensure that the lateral ends of the slat package are stabilized, especially in the support position, these ends are each supported by additional support levers on first frame parts, which extend parallel to the adjusting lever and prevent the slat package from tipping over.

[0010] Preferably, the lumbar support has an auxiliary frame to which all functional parts of the lumbar support are attached, the auxiliary frame being attached to the frame of the slatted base below the lying surface.

[0011] The functional components include, in particular, the second fitting, the third fittings, the actuator, and preferably a motor for electrically operating the actuator, the first adjusting lever, the first steering lever, and further support levers provided for lateral support of the lateral end regions of the slat assembly. The first fittings, the adjusting rod, and the slat assembly are also indirectly attached to the auxiliary frame via the levers. The auxiliary frame is mounted below the slat plane of the slatted frame, with the slats of the slat assembly and the slats of the slatted frame being arranged in the same plane in the initial position. The installation space for the slat assembly is provided by removing the slats of the slatted frame in this area.By arranging the functional parts on the auxiliary frame, all parts can be pre-assembled on the auxiliary frame before it is subsequently attached to the frame of the slatted base.

[0012] It is preferably provided that the auxiliary frame has transverse and longitudinal struts, wherein the first frame parts and the second frame part are longitudinal struts which are attached to the transverse struts and wherein the auxiliary frame is attached to the frame of the slatted frame with the transverse struts.

[0013] The longitudinal struts are oriented perpendicular to the slats when installed, while the transverse struts are parallel to the slats. The subframe is attached to the frame of the slatted base via the transverse struts, for example by welding, screwing, or using a plug-in connection. The longitudinal struts serve to attach the functional components.

[0014] Furthermore, it is preferably provided that a second adjusting lever and a second steering lever are arranged as support levers at each lateral end of the slat package, wherein the second adjusting lever is guided longitudinally with a first end in a third fitting part on the first frame part and is connected with a second end to the adjusting rod, and the second steering lever is rotatably attached with a first end to the first frame part and is pivotally connected with a second end to the second adjusting lever.

[0015] The second steering levers and the second adjusting levers are also functional components that are attached to, or can be attached to, the subframe. These move along with the slat assembly when it is adjusted and support both ends of the slat assembly laterally to prevent tipping when the user applies pressure to the edges of the slat assembly.

[0016] It is preferably provided that the slat package has three slats arranged parallel to each other in a plane, with the first ends of the slats arranged in a first slat holder and the second ends of the slats arranged in a second slat holder.

[0017] The use of three slats provides sufficient support width for the majority of users to optimally support their lumbar region.

[0018] It is particularly preferred that the auxiliary frame is detachably attachable or fixed to the frame of the slatted frame, and it is particularly preferred that the slatted pack of the lumbar support is arranged in a free space of the slatted frame.

[0019] This allows for particularly easy repairs to components of the lumbar support. Furthermore, it is possible to retrofit or replace the lumbar support, all of whose components are held to the subframe. To integrate the slat assembly into the slatted frame, some of the frame's slats are first removed to create a mounting area for the slat assembly. The slat assembly is then positioned within this area, with its slats lying flush with the frame's slats in their initial position.

[0020] An embodiment of a slatted frame according to the invention with a lumbar support is described below and explained in more detail with reference to the figures.

[0021] It shows: Fig. 1 a section of a slatted frame with a lumbar support in a view from below; Fig. 2 a lumbar support in its basic position in a view from a low angle; Fig. 3 the lumbar support in a support position in a view from a low angle; Fig. 4 a section of the lumbar support in a support position in a view from a low angle.

[0022] Fig. 1Figure 1 shows a section of a slatted frame 1 with a lumbar support 2. The slatted frame 1 has a surrounding frame 5 to which a plurality of slats 6 are attached transversely to its longitudinal extent. Bundles of three parallel slats 6 are held at their ends in a pair of slat holders 20 and are fixed to the frame 5 by these holders. The lumbar support 2 has a bundle of slats 3, which also consists of three slats 6 held at their ends in a pair of slat holders 20. The first ends of the slats 6 are arranged in a first slat holder 20, and the second ends of the slats 6 are arranged in a second slat holder 20. The bundle of slats 3 is arranged in a section of the slatted frame 1 that is 'without slats 6', thus providing the necessary clearance for the bundle of slats 3.The slat assembly 3 is adjustable from a basic position, in which the slat assembly 3 lies in the same plane as the slats 6 attached to the frame 5, to a support position, in which the slat assembly 3 is raised out of this plane, by means of a motor-driven actuator 4. To enable the adjustment of the slat assembly 3 relative to the slats 6, the slat assembly 3 is detached from the frame 5 and attached to first fittings 7. The first fittings 7 are attached to the first and second slat holders 20 of the slat assembly 3 and held by an adjusting rod 8 parallel to the slats 6. The adjusting rod 8 is coupled to the actuator 4 via a toggle lever system 9 and is adjustable. The toggle lever system 9 has two levers: a first adjusting lever 12 and a first steering lever 16, which guides the adjusting lever 12 in the desired direction when it is moved.The adjusting lever 12 is longitudinally guided at one end in a second fitting 13 on a second frame part 14 and connected to a plunger 15 of the actuator 4. Longitudinally guided means in the direction of the longitudinal extension of the slatted frame 1, perpendicular to the slats 6. The second end of the adjusting lever 12 is connected to the adjusting rod 8. The steering lever 16 is rotatably attached at one end to the second frame part 14 and pivotally connected at the other end to the adjusting lever 12. Actuation of the motor adjusts the toggle lever system 9 such that the adjusting lever 12 pushes the adjusting rod 8, along with the slat assembly 3, out of the plane of the slats, causing the slat assembly 3 to protrude beyond the plane of the slats in a supported position. To stabilize the lateral ends of the slat assembly 3, particularly in this supported position, they are supported by support levers 10 on the first frame parts 11.As support levers 10, a second adjusting lever 17 and a second steering lever 18 are arranged at each of the lateral ends of the slat assembly 3, wherein the second adjusting levers 17 are each guided longitudinally at one end in a third fitting 19 on the first frame part 11 and are connected at the other end to the adjusting rod 8. The second steering levers 18 are rotatably attached at one end to the first frame part 11 and pivotally connected at the other end to the respective second adjusting lever 17.

[0023] These support levers 10 are moved along with the levers 12,16 of the toggle lever system 9 when the slat package 3 is adjusted and support the slat package 3 laterally.

[0024] A return from the support position to the basic position can also be achieved by actuating the actuator 4.

[0025] The basic position is in the Figure 1 and 2shown, with the adjusting levers 12, 17 and the steering levers 16, 18 positioned in an extended position, in which they are aligned approximately parallel to the plane of the slats. The adjustment into a support position, which is in the Figures 3 and 4 As shown, this is achieved via the driven toggle lever system 9, which is connected on one side to the slat assembly 3 and on the other side to the electrically driven actuator 4, whereby various support positions can be continuously adjusted. In the support positions, the adjusting and steering levers are angled.

[0026] As it is in the Figures 2 to 4 As shown, the lumbar support 2 has a subframe to which all functional parts are attached. This subframe can be found in the Fig. 1The auxiliary frame is attached to the frame 5 of the slatted base 1 as shown, with the auxiliary frame being mounted below the slat level. The functional components include, in particular, the second fitting 13, the third fitting 19, the actuator 4, and preferably a motor for electrically actuating the actuator 4, the first adjusting lever 12, the first steering lever 16, and further support levers 10, which are provided for lateral support of the end regions of the slat assembly 3. The first fitting 7, the adjusting rod 8, and the slat assembly 3 are also indirectly attached to the auxiliary frame via the aforementioned levers. The auxiliary frame can be fully pre-assembled and is mounted below the slat level of the slatted base 1.

[0027] The auxiliary frame has transverse and longitudinal struts, wherein the first frame parts 11 and the second frame part 14 are longitudinal struts which are attached to the transverse struts 21 and wherein the auxiliary frame with the transverse struts 21 is attached to the frame 5 of the slatted frame 1, for example by welding or screwing or by means of a plug connection mounted to the frame 5.

[0028] The longitudinal struts are aligned perpendicular to the slats 6 in the installed position and serve to fasten all functional parts, while the transverse struts 21 are aligned parallel to the slats 6 and serve to fasten the subframe to the frame 5.

[0029] Additional motors or fittings with lever systems can be mounted on the frame 5 of the slatted frame 1, which, for example, enable the adjustment of components of the slatted frame 1, such as a foot section or a back section, as shown in Fig. 1 This is shown as an example.

[0030] The invention is not limited to the embodiment shown, but is variable in many ways within the scope of the disclosure.

[0031] All individual and combination features disclosed in the description and / or drawing are considered essential to the invention.
