Description

[0001] The invention relates to an adjustable slatted bed base with - an outer frame as well as - a lying surface arranged on the outer frame, comprising at least two parts that can be adjusted relative to each other by tilting or pivoting, wherein - at least one part is designed as a pivotable part, which has an inner frame articulated to the outer frame and can be pivoted relative to the outer frame from a flat position to at least one angled position by means of an adjustment unit, and - the pivoting part has a support device for bracing against the outer frame.

[0002] Adjustable slatted bed bases of the type mentioned above are known in various designs from the prior art, for example from DE 298 03 619 U1. Such slatted bed bases are used in the private sector, particularly together with a bed frame and a mattress, but also in the medical and care sectors for hospital, nursing, and senior beds.

[0003] The swiveling arrangement of at least part of the lying surface allows the shape of the bed to be adapted to the user's needs. This is useful both for adjusting to a desired sleeping position and for changing from a sleeping position to, for example, a sitting position. Secure and stable support for the entire lying surface, including its swiveling parts, is essential.

[0004] Furthermore, since some users utilize parts of an adjustable lying surface, particularly an adjustable leg section, to facilitate getting out of bed, a particularly stable support of these parts of the lying surface against the outer frame is especially important to prevent unintentional lowering and thus injury to the user.

[0005] The support devices known from the prior art, however, have the disadvantage that the pivoting part of the lying surface, due to its connection to the outer frame via the support device, can no longer be easily fully opened to allow access to the space beneath the slatted frame, for example, for cleaning or use as storage space. At the very least, this necessitates the time-consuming process of unhooking the support device to open the bed and then reattaching it when closing the bed. In particular, it is difficult with the prior art devices to fold down a pivoting part of the lying surface in a pivoted position to gain access to the space beneath the slatted frame and then to return the support device to a functional state when closing the bed.

[0006] US Patent 6,826,793 B2 discloses a slatted bed base with a leg section comprising a lower leg section pivotably connected to the thigh section. A guide or support device is arranged below the lower leg section, which can be disengaged from the outer frame when the lower leg section is manually lifted. A disadvantage is that, due to the design of the guide or support device and its rigid attachment to the lower leg section, the free end of the lower leg section remains in a potentially uncomfortable position close to the frame when the thigh section is lifted, for example, by means of an adjustment mechanism.

[0007] The invention is therefore based on the objective of providing an adjustable slatted frame which has an adjustable part that allows easy access to an area below the slatted frame in any operating position and can be quickly and easily returned to an operational and comfortable state.

[0008] The problem is solved according to the invention by a device according to claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

[0009] The adjustable slatted frame comprises an outer frame and a lying surface arranged on the outer frame, having at least two parts. At least one of the parts of the lying surface can be pivoted relative to the outer frame from a flat position to at least one angled position by means of an adjustment unit, and this pivotable part further comprises a support device for support against the outer frame. A characteristic feature of the slatted frame according to the invention is that the support device is designed such that, for adjusting the pivotable part from any set position to an open position, it can be disengaged from the outer frame and, upon pivoting back to the set position, automatically engages with the outer frame in a supporting manner.

[0010] The adjustable slatted frame according to the invention offers several advantages over slatted frames known from the prior art: firstly, it provides stable support for the pivoting part of the lying surface relative to the outer frame, and secondly, it allows the pivoting part to be easily moved from any position into an open position to provide access to the area beneath the slatted frame. Subsequently, the pivoting part can be returned to its original position without any manual intervention in the support mechanism. This allows for versatile use and easy cleaning of the space beneath the slatted frame according to the invention.

[0011] A slatted frame is understood to be any device suitable as a base for at least one upholstered element, in particular a mattress, or for any other device on which to sleep, such as a bed or other piece of furniture for resting or sleeping. Specifically, a slatted frame is a component or assembly that can be placed on a bed frame to support such an upholstered element. Furthermore, a slatted frame can have any number of other functions.

[0012] In principle, a slatted frame has an outer frame, which can be made of a single piece or multiple pieces, and is constructed from any material. Preferably, the outer frame is made of metal, plastic, wood, a composite material, or a combination of several of the aforementioned materials. The outer frame can enclose the slatted frame on all four sides or consist of just two lateral components connected by connecting elements. Essentially, the outer frame is the component that provides the slatted frame with the necessary dimensional stability.

[0013] The term "lying surface" generally refers to the component or assembly located on the side of the slatted frame where the upholstered element is to be placed, or which faces the user. The lying surface can be composed of a variety of different components, preferably elastic elements made of wood, plastic, or metal. In particular, the lying surface can have multiple parallel slats made of wood or plastic, or parallel or grid-like metal or wire elements. These elastic elements can be directly connected to the outer frame or form part of an assembly attached to the outer frame.

[0014] The slatted frame according to the invention comprises a lying surface which has at least two parts, wherein these parts are structurally separate sections of the lying surface which are adjustable relative to each other, preferably by pivoting or tilting.

[0015] An adjustment unit is generally understood to be a component or assembly suitable for adjusting at least one pivotable part of the lying surface relative to the outer frame or relative to the other part of the lying surface, in particular for varying the angle between two parts of the lying surface. This can be either a purely mechanical device or an electrically adjustable device.

[0016] A flat position of the pivoting part of the lying surface is defined as the position in which this part of the lying surface is parallel to the outer frame and / or in the same plane as the rest of the lying surface. This flat position is the position in which the pivoting part of the lying surface has the smallest possible adjustment angle, usually around 0°, relative to the outer frame or the rest of the lying surface.

[0017] In contrast, the angled position is fundamentally a position of the swiveling part of the lying surface characterized by an angle that differs from the adjustment angle of the flat position. Specifically, the angled position refers to the position of the maximum possible adjustment of the swiveling part of the lying surface relative to the outer frame by means of the adjustment unit. In principle, angles of the adjustable part of the lying surface relative to the outer frame of up to 90° are conceivable, and in some special applications, even greater angles are possible.

[0018] The "any set position" therefore refers to a position of the swiveling part of the lying surface relative to the outer frame or the rest of the lying surface that lies between the flat position and the maximum possible angled position. The adjustment to the set position is always made using the adjustment unit. Depending on the type of adjustment unit, any of the possible positions between the flat position and the angled position can be continuously adjusted, or only a predetermined, discrete number of set positions may be available.

[0019] The term "fold-out position" refers to a position of the pivoting part of the lying surface in which the pivoting part is moved by a user without any action from the adjustment unit, thus providing access to the space beneath the slatted frame. With the slatted frame according to the invention, it is fundamentally possible to move the pivoting part of the lying surface into a fold-out position from any set position. Furthermore, the pivoting part of the lying surface can be designed such that, when pivoted into the fold-out position, it can be moved beyond its maximum possible angled position.

[0020] The term "re-swinging" refers to the process by which a user moves the swiveling part of the lying surface from the unfolded position to the set position without using the adjustment unit, in which the swiveling part of the lying surface was located before being adjusted by the user to the unfolded position.

[0021] The support device can be any single-piece or multi-piece assembly designed to support the pivotable part of the lying surface against the outer frame, with the support occurring independently of any adjustment of the pivotable part by means of the adjustment unit. In particular, in every possible set position of the pivotable part, there is an effective connection between the support device and the outer frame; that is, the support device and the outer frame are always engaged in a supporting manner.

[0022] In contrast, when a user adjusts the swiveling part of the lying surface into the unfolded position, the functional connection between the support device and the outer frame is terminated, meaning that the support device comes out of engagement with the outer frame.

[0023] When pivoting back, the support device automatically re-establishes contact with the outer frame. In this context, "automatic" means that the user does not need to perform any manipulations on the support device to re-establish the contact. That is, the support device re-engages without contact and without any action from the user.

[0024] According to the invention, the lying surface, in particular the pivotable part of the lying surface, comprises an inner frame arranged on the outer frame. The inner frame can be formed in one piece or in multiple pieces from any material. Preferably, the inner frame is made of metal, plastic, wood, a composite material, or a combination of several of the aforementioned materials, and particularly preferably of the same material as the outer frame. The inner frame can surround the lying surface or the pivotable part of the lying surface on all four sides or consist of only two lateral components connected to each other by connecting elements. In a particularly advantageous embodiment of the invention, the inner frame is pivotably arranged directly on the outer frame, thereby enabling the pivotability of a part of the lying surface in a particularly simple manner.

[0025] Furthermore according to the invention, the support device is articulated with the pivotable part of the lying surface, preferably with the inner frame, and has a stop element to limit the pivotability of the support device relative to the pivotable part of the lying surface, thereby ensuring in a particularly simple way that when pivoting back, the support device automatically engages with the outer frame again.

[0026] According to a preferred embodiment of the invention, the support device comprises a lever which is fixed to the pivotable part of the lying surface, preferably to the inner frame, by means of a fitting having the stop element.

[0027] In an advantageous embodiment of the invention, a support device is arranged on each of two opposite sides of the pivotable part of the lying surface, thereby enabling particularly stable support in a simple manner. Each of the two support devices is arranged on the side of the inner frame that is pivotably fixed relative to the outer frame.

[0028] According to a preferred embodiment of the invention, the support device comprises a receiving element arranged on the outer frame, which interacts with the lever in every position between the flat position and the angled position, wherein the receiving element is preferably arranged on a side of the outer frame facing the pivotable part of the lying surface, thereby enabling a particularly simple support of the lever on the outer frame, a particularly economical manufacture of the outer frame and a particularly versatile adaptability of the support device to the respective requirements.

[0029] According to an advantageous embodiment of the invention, the receiving element has a sliding surface and a stop surface for the lever, wherein the lever rests against the stop surface in every position between the flat position and the angled position. The sliding surface is particularly preferably arranged parallel to the outer frame and / or the lying surface. Likewise, the stop surface is preferably designed perpendicular to the outer frame and / or the lying surface.

[0030] According to a further advantageous embodiment of the invention, the sliding surface is formed in such a way that when the lever pivots from the unfolded position into any angled position or into the flat position, it engages with this position and is guided sliding on it until it reaches the stop surface, thereby ensuring in a simple way that the lever automatically engages again when the pivotable part of the lying surface is pivoted back, regardless of the set position.

[0031] According to a preferred embodiment of the invention, the lever is arranged such that the angle between the sliding surface of the receiving element and the lever in the direction of the stop surface is greater than 90° when pivoting from the open position into any angled position or the flat position, thereby ensuring that the lever always slides along the sliding surface towards the stop surface.

[0032] A preferred embodiment of the invention comprises an electric motor and, particularly preferably, a spindle drive as part of the adjustment unit, by means of which the pivotable part of the lying surface can be pivoted steplessly from the flat position to a maximum adjusted position, thereby making it particularly easy for a user to adjust the slatted frame.

[0033] According to a preferred embodiment of the invention, the lying surface comprises a leg section and / or upper body section that can be pivoted relative to the outer frame. Preferably, the pivotable leg section is formed from a thigh section and a lower leg section, which are articulated together. Furthermore, preferably, the pivotable upper body section is formed from a back section and a head section, which are articulated to one another. Such embodiments make it possible, in a particularly simple manner, to achieve a wide range of adjustability and customization of the adjustable slatted frame.

[0034] According to a further preferred embodiment of the invention, the distance between the outer frame and at least a part of the lying surface, preferably at least a pivotable part of the lying surface and particularly preferably all pivotable parts of the lying surface and most preferably the inner frame, is at least 25 mm, preferably at least 28 mm, which prevents the user, in particular their fingers, from being pinched when adjusting the slatted frame between parts of the lying surface, in particular the inner frame and the outer frame, in a particularly simple manner.

[0035] An embodiment of the adjustable slatted frame according to the invention is explained in more detail below with reference to the drawings. The figures show: Fig. 1. A perspective view of an adjustable slatted bed base with one leg section in an angled position, Fig. 2 a perspective view of the in Fig. 1.

Slatted frame shown with a lower leg section of the leg section in an open position and an upper body section in an angled position, Fig. 5 a perspective view of the slatted frame with a thigh part of the leg section in a flat position and the lower leg part of the leg section in a folded-up position and Fig. 6 A schematic top view of the slatted frame.

[0036] A in Fig. The adjustable slatted frame 1 shown in Figure 1 has an outer frame 2 surrounding the slatted frame 1. A lying surface 3 is arranged on the outer frame 2 and is formed from several parts 4, 5 that can be pivoted relative to each other. Each of the parts 4, 5 of the lying surface 3 consists of an inner frame 8 surrounding the part 4, 5 and elastic wooden slats 23 arranged thereon. The inner frames 8 are each arranged within the outer frame 2.

[0037] In order to be able to pivot the movable parts 4, 5 of the lying surface 3 relative to the rest of the lying surface 3 or relative to the outer frame 2, the inner frame 8 is pivotally connected to the outer frame 2 and an adjustment unit 6 is arranged between the outer frame 2 and at least one of the movable parts 5 of the lying surface 3.

[0038] To support the pivotable part 4 of the lying surface 3, a support device 7 is arranged on both sides S1, S2 of the inner frame 8 of the pivotable part 4 (see Fig. 2), which supports the pivotable part 4 of the lying surface 3 against the outer frame 2, wherein in each operating position of the pivotable part 4 set by means of the adjusting unit 6, the support device 7 is operatively connected to the outer frame 2 by means of a lever 10. The angle W1 between the lever 10 and the outer frame 2 or the sliding surface 13 of a receiving element 12 arranged on the outer frame 2 is always less than 90° (see Fig. 3b).

[0039] Furthermore, the pivoting part 4 and the support device 7 are designed such that the pivoting part 4 can be manually unfolded further by a user in any position of the pivoting part 4 set by the adjustment unit 6 (see Fig. 2 and Fig. 5) to gain access to the space below the slatted frame 1, whereby when the pivoting part 4 is manually opened, the lever 10 of the support device 7 is disengaged from the outer frame 2 or the receiving element 12 arranged thereon.

[0040] Furthermore, the support device 7 is designed such that when manually folding back from an open position to the position of the pivotable part 4 previously set by means of the adjustment unit 6, the lever 10 always automatically engages with the outer frame 2 or the receiving element 12 without having to be guided or engaged by the user, for example.

[0041] The part of the support device 7 located on the inside of the inner frame 8, facing away from the outer frame 2, is in Fig. Figure 3a shows in detail. A fitting 11 is fixed to the inner frame 8, to which the lever 10 is pivotally attached. Furthermore, the fitting 11 has a stop element 9 in the form of a bolt, which is arranged on the fitting 11 in such a way that the maximum pivoting range of the lever 10 relative to the fitting 11 or to the inner frame 8 of the pivotable part 4 is limited. In particular, the stop element 9 is arranged such that when the lever 10 is folded down from an open position by a user, it does not hang continuously vertically or along the plumb line, but rather that at least shortly before reaching the position of the pivotable part 4 set by means of the adjusting unit 6, the lever 10 comes into contact with the stop element 9 and is thereby pushed out of the vertical or plumb-line position.

[0042] According to the detailed description in Fig. 3b The receiving element 12, arranged on the outer frame 2, has, in addition to the sliding surface 13 which runs parallel to the outer frame 2, a stop surface 14 which is arranged substantially perpendicular to the sliding surface 13. Furthermore, the receiving element 12 includes a limiting flange 24 extending along the sliding surface 13 and substantially perpendicular to it, which is provided to guide the lever 10 laterally and / or to prevent the lever 10 from jumping off the receiving element 12.

[0043] The adjustable slatted frame 1 includes - as in the Fig. 4 and Fig.Figure 6 shows a leg section 17 movable relative to the outer frame 2, which is formed from a thigh section 5 arranged on the outer frame 2 and a lower leg section 4 articulated to the thigh section 5. The thigh section 5 is infinitely adjustable relative to the outer frame 2 by means of an adjustment unit 6 formed from an electric motor 15 and a spindle drive 16 interacting with it, while the lower leg section 4 has a support device 7 on both sides for support against the outer frame 2. Furthermore, the slatted frame 1 comprises an upper body section 18, which is formed from a back section 21 pivotably arranged on the outer frame 2 and adjustable by means of an adjustment unit 6, and a head section 22 articulated to the back section 21.

[0044] The distance A between an inner side of the outer frame 2 facing the inner frame 8 and the inner frame 8 of all moving parts 4, 5, 17 - 22 of the lying surface 3 is at least 28 mm to prevent a user from being trapped during operation of the adjustable slatted frame 1.
