Description

Motorized functional fitting for a box spring bed

Technical Field

The invention relates to a motorized functional accessory for a box spring bed.

The box spring bed includes: a bed frame having two frame side portions extending in a bed longitudinal axis and a head frame portion and a foot frame portion extending laterally between the frame side portions at a head end and a foot end; and an intermediate plate extending between or above the side portions in a lying plane. At the head end of the intermediate plate, which is oriented towards the head end of the bed frame, the head plate is swingably arranged about a head plate swing axis extending transversely to the longitudinal axis of the bed. Furthermore, the foot plate is arranged swingably about a foot plate swing shaft which also extends transversely to the bed longitudinal axis. The plate-like middle plate, the head plate and the foot plate together form a bed surface for supporting a mattress.

The functional accessory includes a longitudinal carrier extending along a carrier longitudinal axis, the longitudinal carrier configured for connection with a box spring bed. Preferably, the longitudinal support is configured as a quadrilateral or rectangular profile.

The stand-up support is rotatably hinged to the longitudinal carrier at a rotation point. Finally, a linear drive is provided which extends or acts between the longitudinal carrier and the standing bracket and converts the rotational movement of the electric motor into a translational movement of the lifting tube. The linear drive is preferably designed as a linear drive. The lifting tube is rotatably connected to the lifting support in such a way that, when the linear drive is operated, the lifting support can be moved from a lowered initial position into a lifting position which forms an acute angle with the carrier longitudinal axis of the longitudinal carrier and can be adjusted preferably steplessly in order to lift or lower the head or foot part from or into the lying plane.

Background

That is, the functional attachments are fixed with the bed frame of the box spring bed and serve to transition the headboard and footboard from a lowered initial position in which they extend in a plane having a horizontal lying plane to a raised position lifted from the lying plane.

That is, the bed frame includes two frame side portions extending along the bed longitudinal axis at parallel spacing from each other, connected to each other at the head and foot ends by a head frame portion and a foot frame portion to constitute a generally rectangular closed frame that rests directly on the floor or on a drawer or stand, foot or the like that spaces the frame from the floor. The box spring mattress may be placed in a lying plane consisting of a middle plate, a head plate and a foot plate.

The functional fitting is connected, in particular screwed, to the bed frame in order to move the headboard and footboard by means of a motor drive.

The longitudinal carrier extends here from the head frame part up to the foot frame part, i.e. is fixed to the bed frame at the upper and lower ends of the bed frame. The longitudinal carrier furthermore centrally receives a double drive, the electrically operated lifting tube of which operates as a lifting bracket for pivoting the head part and as a lifting bracket for pivoting the foot part. In other words, in the prior art, the linear drive is configured as a double drive, which is arranged centrally in the longitudinal carrier, wherein the double drive is fixed together with the longitudinal carrier at the rear end and is rotatably articulated by means of a respective lift tube, which is adjustable longitudinally relative to the fixed outer tube, with the headboard-stand and with the footboard-stand. In the prior art, the longitudinal support thus extends essentially along the entire longitudinal bed axis, i.e. is constructed as long as the length of the bed frame, and is subjected to the prevailing forces of the lifting frame and the linear drive.

The longitudinal support must therefore be correspondingly stably configured in order to be able to withstand the forces, which is preferably achieved by the longitudinal support being configured as a rectangular or quadrangular profile having a particularly good equatorial moment of inertia against bending stresses.

Such a functional fitting for a box spring bed is known, for example, from DE 10 2016 116 256 A1. The longitudinal carrier configuration disclosed in this document is a continuous profiled rail extending from the head end of the bed frame up to the foot end. The lifting bracket (sometimes also referred to as lifting lever) is likewise rotatably hinged with its rear end to the longitudinal carrier and can be pivoted by means of a central double drive from a lowered, horizontally extending starting position relative to the longitudinal carrier into a lifted position which is lifted, i.e. at an angle to the carrier longitudinal axis of the longitudinal carrier. Typically, the lifting position can be adjusted here in the range between 0 ° and approximately 45 ° to the carrier longitudinal axis.

However, this type of functional fitting has the disadvantage that the length of the bed determines the length of the longitudinal carrier and the length of its profiled rail. Thus, for each bed length and for each bed variant, different shaping rails or different functional fittings with different longitudinal carriers must be provided. This depends on a large number of variants, since there is no unified standard for box spring beds to date. This greatly increases the warehouse cost.

Transportation of the functional accessories is also problematic, as the functional accessories are typically much longer than typical tray sizes, which typically have a size of 80 x 120 cm. In this respect, special dimensions must always be provided in the storage space, which is costly.

Disclosure of Invention

Starting from the disadvantages mentioned, the object of the invention is therefore to at least partially avoid the disadvantages that occur in functional fittings of this type and in particular to provide a motor-driven functional fitting that is particularly variable, easy to transport, but at the same time very stable.

This object has been achieved by the features of the independent claims. Preferred, however non-mandatory, features are described in the dependent claims.

In a most conceptual embodiment, this object has been achieved in that the longitudinal carrier comprises an end face (external in the installed position) which is designed for fastening to the head frame part or the foot frame part. The longitudinal support comprises an inner end face, which is opposite the outer end face and which is fitted into the bed frame in the installed position, and which is designed for fastening to the intermediate plate. Furthermore, the drive is arranged beside the longitudinal carrier, i.e. fixed thereto, and the stand is rotatably hinged to the longitudinal carrier at the lower fixed end in the mounted position. This means that the stand is rotatably and pivotally hinged to the longitudinal carrier at its outermost end as far as possible in order to obtain as large a lever arm as possible. Finally, the relatively movable lifting tube of the linear drive is rotatably engaged with the lifting frame at a swinging end spaced apart from the fixed end along the longitudinal axis of the lifting frame. By means of this embodiment, a particularly efficient force expansion of the lifting tube to the lifting support is achieved by means of a particularly long lever arm, so that a linear drive with a power of 1/3 less than this existing functional fitting can be used.

That is to say, the longitudinal support is designed according to the invention for fixing the end which points outside the bed frame in the installed position directly or indirectly to the bed frame at the head end or the foot end, and is designed for fixing on the middle part at the opposite end.

The linear motor, which is rotatably hinged with its lower motor end on the outer end face in the installed position, and the standing bracket, which is rotatably oriented with its lower fixed end toward the inner end face, thus preferably form an isosceles triangle together with the longitudinal carrier in the lifted position, although this is not mandatory for the working mode of the invention.

The pivotable articulation is preferably carried out by means of a fork-shaped articulation, which is arranged in particular on the linear motor at the rear motor end and on the front lifting tube, or by means of a profile which is rotatably coupled to a shaft arranged in the longitudinal carrier.

According to the invention, the functional fitting is thus configured such that the lower motor end of the linear drive is oriented in the installed position toward the outer end of the longitudinal carrier, and the lower fastening end of the stand is oriented in a rotationally articulated manner toward the inner end of the functional fitting.

The lifting tube of the linear drive, which is received in a relatively movable manner in the housing of the linear drive, is rotatably hinged to the upper end of the lifting bracket as far as possible, so that and thus a particularly efficient force expansion of the toggle lever formed in this way is achieved, while the functional fitting is at the same time constructed very flat in the lowered initial position.

In other words, in a bed with separate, relatively movable head and foot plates, separate longitudinal supports are involved, which are screwed to the bed frame with their end faces, which are on the outside in the installed position, toward the head or foot end of the bed frame and are fastened to the intermediate plate with their end faces toward the intermediate plate.

Preferably, the fixing on the intermediate plate is performed by corner piece profiles laterally fixed on the longitudinal carrier, said corner piece profiles being laterally fixed on the longitudinal carrier with vertical legs extending in the mounted position and being screwed on the underside of the intermediate plate with horizontal legs extending at right angles to said vertical legs. The corner piece profile, which is preferably made of steel sheet, acts at the same time on the intermediate plate in a stable manner, in order to prevent buckling when a person sits.

When the rear motor end of the linear drive is engaged, in particular rotatably articulated, with the outer end of the longitudinal carrier and the fixed end of the stand is engaged, in particular rotatably articulated, with the inner end of the longitudinal carrier, a particularly coordinated force expansion and thus a particularly low power of the electric motor of the linear drive is required. The maximum power of the electric motor is required for lifting the lifting bracket from the lowered initial position, since here the vertical force for lifting is minimal. If the first 10 to 15 percent of the adjustment travel is overcome, the electric motor is only slightly loaded.

For the lowest possible power supply of the linear drive, it is advantageous if the rear end of the linear drive, i.e. the end with the housing and the electric motor, is fastened, in particular rotatably articulated, to the longitudinal support. In a particularly preferred embodiment, additional holding blocks can thus be provided on the inner side on the head-side and foot-side parts which extend vertically in the installed position, to which holding blocks the rear end of the linear drive can be fastened or fastened. The holding blocks, which are sometimes also referred to as fastening beams, fastening blocks, transverse carriers or transverse beams, extend transversely to the longitudinal axis of the bed, preferably at the inner side of the head or foot frame part, between the frame side parts, ending with the lower edges of the frame side parts at the lower ends of the head or foot frame part, and form bearing edges, which are arranged offset inwardly from the bed frame, to which the end sides of the functional fittings can be fastened.

Preferably, the corner piece profile is rotatably fastened to the rear end by means of a rear fork-shaped joint, said corner piece profile being able to be attached to and screwed to the fastening beam or fastening block.

Preferably, the fastening beam or fastening block is arranged both on the head-side part and on the foot-side part in order to achieve the lowest possible point of force application of the rear fastening end of the linear drive, in particular of the rear fork-shaped articulation. A further advantageous embodiment of the force profile is achieved in that the front end of the linear drive, in particular the front end of the relatively movable lifting tube, engages as far above as possible with the lifting support, i.e. with a point which is as far as possible from the lower fixed end of the lifting support on the longitudinal carrier. As a result of this configuration of the functional fitting, in the lowered initial position, a tilt of the linear drive is already achieved which is as large as possible, so that less power is required for the electric motor of the linear drive than in the prior art.

In a particularly preferred embodiment, the front end of the linear drive, in particular the relatively movable lifting tube, is joined to a transverse bar which extends between two profile sections or profile carriers of the lifting bracket which are widened in a fork-like manner. This thus enables a particularly low rotational point of the rear end of the linear motor and thus a relatively flat structure of approximately 7-11mm of the bed or of the bed frame, whereby it is possible to also arrange drawers or understructures below the actual bed frame without significantly increasing the structure of the overall system.

That is to say, according to the invention, the longitudinal carrier and the linear drive and the lifting bar are specific functional components which can be fastened to the basic frame or to the assembled bedframe with the sitting and lying plate. The functional fitting according to the invention is thus transported, packaged and handled significantly better for professionals and end consumers than in the prior art.

According to the invention, the configuration can thus also be used for so-called split beds, which are separated in the center, in particular for transport in small stairwells. In the split bed, the sitting and lying part is split centrally on the longitudinal axis of the bed frame and the two window parts are plugged into each other in the final assembly. That is, in the split bed, the head base frame portion and the foot base frame portion each include respective components that together have the functional fitting according to the present invention.

The proposed functional accessory can be adapted to different bed lengths and widths by adjusting the longitudinal carrier and can be used for bed lengths of 1.90m to 2.10m and longer, virtually completely independently of the bed length.

Embodiments may include a transverse carrier extending transversely to the longitudinal axis of the longitudinal carrier for securing the longitudinal carrier to the sitting and lying plate in order to better prevent possible buckling of the sitting and lying plate, in particular in the case of heavier persons. In a typical configuration, the transverse carrier is approximately one fifth of the width of the bed frame, but may also extend up to 80% of this width, depending on the manner of construction.

The preferred embodiment comprises that the support plate is divided into an upper support plate and a lower support plate, which are connected to each other swingably about a further swing axis. In order to achieve a relative movement of the upper and lower support plates with respect to one another during the setting, the stand for the foot part is preferably screwed to the lower support plate by means of corner piece profiles. In contrast, in the case of an upright support for a head plate, it is sufficient if the upright support provided here rolls with rollers on the underside of the head plate, i.e. is not screwed to the head plate.

The fastening of the fitting to the bed frame is generally carried out directly, particularly preferably by means of screws. In order to be able to adapt to different bed frame sizes and bed frame heights, the fitting can also be fastened between them directly, for example by using spacer blocks, to an engagement partner which is arranged between the functional fitting and the engagement partner.

In order to adapt the functional attachment to different bedframes, i.e. bedframes having different lengths and widths, the functional attachment can furthermore be configured "adaptively". This means that the longitudinal carrier, together with the linear drive fastened thereto and the lifting bracket, remains unchanged as a basic unit, so that the leverage ratio and the arrangement of the joints relative to one another remain unchanged, whereas the end regions, i.e. the outer end sides, can be configured adaptively, i.e. to be adapted to the respective length and width of the bed.

The adaptive configuration can be arranged not only on the outer end face, i.e. in the mounted position, facing the head frame side part or the foot frame side part, or on the inner end face, in the mounted position, facing the intermediate plate, or on both end faces.

The adaptation is performed by means of end-side adapters which can be connected to the respective end sides of the carriers in order to lengthen the respective carrier, i.e. the longitudinal carrier extending over the longitudinal axis of the bed or the transverse carrier extending transversely to the longitudinal axis, in order to lengthen or shorten the carrier and thereby adapt the carrier to different frame lengths and frame widths.

Each end-side adapter comprises a proximal longitudinal carrier-securing section for securing to a carrier, i.e. a longitudinal carrier or a transverse carrier, and a distal frame-securing section for securing to a frame-side portion.

Preferably, the end-side adapter is configured to variably mate with different frame lengths and/or frame widths. This is preferably achieved by providing an insert profile which is configured to correspond to the internal structure of the carrier and which can be inserted or pushed into the respective carrier in this respect.

Preferably, locking means are furthermore provided in order to fix the end-side adapter in the respective carrier in the desired defined position for achieving the defined length.

The frame fixing sections can in turn be configured differently. The frame fastening section may, for example, comprise a fitting corner piece which serves as a support corner piece and is in principle configured as an inner corner piece, i.e. a support leg which rests on the inner edge of the bed and a contact leg which rests on the inner face. Preferably, the two legs, i.e. the support leg and the abutment leg, form an angle of 90 °, wherein this, however, of course, matches the corresponding edge of the bed, i.e. in principle, further angles between the legs are also conceivable. The fitting corner piece can in any case rest on the inner edge of the bed and preferably on the inner edge of the transverse carrier, the longitudinal carrier, but also directly on the inner edge of the frame-side part, i.e. the head frame-side part or the foot frame-side part or the frame-side part. In a further embodiment, the frame fastening section is configured as a mounting flange, i.e. as a planar element which is connected to the longitudinal carrier fastening section and can be screwed to the inner side of the frame-side part or to the inner side of the head frame part or the foot frame part.

The longitudinal carrier fastening sections can also be configured differently and preferably in such a way that they are connected to the longitudinal carrier in different, predetermined positions. In a particularly preferred embodiment, the longitudinal carrier fixing section comprises an insertion part or body which can be inserted into the longitudinal carrier and can be adjusted and differently oriented relative to the longitudinal carrier.

Particularly preferably, the end-side adapters arranged on the respective end sides of the longitudinal carrier are adjustably fastened or can be fastened to the longitudinal carrier. Preferably, this is achieved by a corresponding insertion region or insertion section which can be inserted or pushed into a longitudinal carrier, preferably configured as a hollow profile. The end-side adapter is thus formed, which comprises at the outer, distal end a fitting corner or a fitting profile or a fitting flange and has an insertion section extending transversely to the fitting corner, i.e. in the longitudinal direction, to the longitudinal carrier, which insertion section can be pushed into the longitudinal carrier, preferably with a corresponding clearance fit, and can be moved relative to the longitudinal carrier.

However, it is also possible within the framework of the invention for the fitting angle or fitting flange to be fixed, in particular welded, in a non-adaptive manner to the distal end face of the longitudinal support, which is the preferred embodiment if the longitudinal support is formed as a steel profile.

In this case, preferably, an external fitting corner piece is provided on the outer end face of the foot frame side part or of the head frame side part in the installed position, and a transverse beam can be formed on the inner end face of the intermediate part in the installed position, i.e. it preferably extends with the longitudinal carrier on the frame side part, i.e. the lower end of the frame, and can also be screwed on the inner side directly, for example by means of a corresponding fitting flange for screwing on the inner side of the frame side part, in addition to being fixed on the upper side to the intermediate plate.

In an adaptive embodiment, the cross beam, that is to say in the installed position, extends transversely to the longitudinal axis of the longitudinal carrier and thus parallel to the head frame side part and the foot frame part in the transverse direction of the bed, can also be adapted to different width configurations of the bed. In a preferred embodiment, this is achieved in turn by means of an end-side adapter which is telescopically inserted or pushed into the transverse beam for fastening to the inner side of the frame-side part.

The adaptation of the longitudinal carrier on its end face, i.e. on the outside in the longitudinal direction of the bed, can likewise be achieved by such an end face adapter which is now telescopically connected to the longitudinal carrier, i.e. which comprises a proximal insertion section for insertion into the interior cavity of the longitudinal carrier and comprises a flange or mounting flange which is arranged on the outer end transversely to the insertion section and extends transversely to the insertion section and is intended to be fastened to the head frame side part or the foot frame side part. In this configuration, a transverse carrier or retaining or fastening block can thereby be dispensed with, which is arranged on the inside between the frame-side parts on the head frame-side part or the foot frame-side part in a horizontally extending manner.

However, an adaptive configuration or an adaptive adaptation of the longitudinal carriers may also be suitable in the case of using such transverse carriers on the frame. In a further embodiment, for example, an external end-side adapter is provided, which in turn has a proximal insertion section that can be inserted into the longitudinal support, i.e. is preferably configured complementarily to the internal structure of the longitudinal support, which is preferably rectangular or square in cross section, and which is provided at its distal outer end with a corner piece profile that rests on the inside with a vertical leg on the transverse support and on the upper side with a horizontal leg extending transversely to this vertical leg on the transverse support.

In an alternative embodiment, the embodiment can also be used for direct, i.e. indirect, fastening to the inner face of the head frame side part or of the foot frame side part, i.e. without a transverse carrier or cross beam on the inner side.

Usually, end-side adapters are used, which can be connected to the respective end sides of the longitudinal support, which are particularly preferably configured with insert profiles matching the cross section of the longitudinal support, i.e. insert profiles or insert ends which are configured complementarily to the internal structure of the longitudinal support, and on the distal, outer end side of the insert profiles corresponding fitting angles or fitting flanges are provided. The end-side adapter is preferably designed as a steel profile, in particular as a welded steel profile, i.e. as a weld.

In order to match the exact length of the different, however standardized bed lengths, i.e. typically 2 meters, 2.10 meters or 2.20 meters, locking means may be provided between the received longitudinal carrier and the inserted insertion section of the end-side adapter. Preferably, the locking means comprise a through-hole arranged extending transversely in the longitudinal carrier, into which a cotter pin or dowel can be inserted, and which cotter pin or dowel then cooperates in the installed position with a differently configured transverse hole in the insertion section of the end-side adapter in order to lock the cotter pin or dowel relative to the longitudinal carrier over a length that is correspondingly matched to the bed length.

The end-side adapter can, as previously described, have a fitting corner piece at the distal end, i.e. it comprises a corner piece profile at the distal end side, which has a vertical leg extending vertically in the installed position for internal abutment against the transverse carrier or the transverse beam, and a horizontal leg extending transversely to the plane of the vertical leg, which can rest or rest on the upper side of the transverse carrier.

In an alternative embodiment for a bed without transverse carriers or beams inside the head frame part or the foot frame part, the end-side adapter can also simply have a plate-shaped flange which extends transversely to the insert part at the end side, preferably welded to the insert part at the outer end side and is fixed, preferably screwed, in the mounted position on the inner side of the lower part of the head frame side part or the foot frame side part.

For a bed frame without transverse carriers or beams, the end-side adapter can also be designed such that the fitting corner piece can be fastened to the inner side of the vertically extending head-frame side part or foot-frame side part, for which purpose the fitting corner piece in turn comprises a vertical leg which is attached on the inner side to the inner side of the frame side part, at the upper end of which vertical leg a horizontal leg is designed transversely to the plane of the vertical leg, which horizontal leg can also be placed or mounted on the upper edge of the head-frame side part or foot-frame side part.

In order to rotatably fix (hinge) the linear drive and/or the lifting support to the longitudinal support, a preferably U-shaped fixing angle can be provided laterally, in whose outer legs an opening is formed, to which the linear drive, in particular the rear fork-shaped pivot, is rotatably fixed by means of a pin. The fixing corner piece preferably comprises an inner leg which is connected on the inside to the longitudinal carrier in the installed position, a transverse leg extending transversely to the plane of the inner leg, which then transitions into an outer leg which preferably extends parallel to the inner leg, in which the hole is then formed. The fixing angle is preferably connected with its inner leg on the outside to the longitudinal carrier, preferably welded to the longitudinal carrier.

The fixing corner pieces are preferably fastened laterally with inner legs on the longitudinal carrier at a location optimally predetermined for the respective bed length, in particular 2m, 2.10m or 2.20m, wherein the fastening in the case of the shortest bed of 2m preferably takes place directly at the end face with lateral legs extending parallel to the end face of the longitudinal carrier up to the inner legs. In the configuration for a bed length of 2.10m, the fixing angle is fixed on the outside of the longitudinal carrier along the longitudinal axis of the longitudinal carrier offset relative to the center of the bed, i.e. offset by about 10cm with the inner leg, which means that there is a distance of about 10cm between the end side of the longitudinal carrier and the lateral leg of the fixing angle. Correspondingly, an embodiment of a bed length of 2.20m is suitable, wherein the distance between the end face of the longitudinal carrier and the transverse beam of the fixing corner piece is approximately 20cm.

According to the invention, the fixing angle with an opening for rotatably fixing the lower end of the stand or the linear drive can also be used in embodiments which are not configured adaptively, i.e. do not comprise an end-side adapter which can be adjusted relative to the longitudinal carrier, i.e. in embodiments in which an assembly flange for fixing on the inner side of the respective frame-side part or an assembly angle for fixing on the transverse carrier or the frame-side part is provided thereon extending transversely on the end side of the longitudinal carrier.

The fixing angle with the opening or the fixing eyelet can be provided in all embodiments of the functional fitting, preferably by means of welding, for laterally rotatably fixing the linear drive or the lifting bracket to the longitudinal carrier. In all cases, the fixed corner fitting comprises: an inner leg which can be fastened or can be fastened laterally to the longitudinal carrier; a lateral leg extending outwardly transverse to the plane of the inner leg; and an outer leg which in turn extends transversely to the plane of the transverse leg and preferably parallel to the inner leg, an opening or through-hole being provided in said outer leg.

In the course of the present invention, it is generally clear to the person skilled in the art that for the desired space optimisation and stability, a particularly low fastening of the functional fitting to the frame-side part is expedient, so that the end-side adapter is preferably designed such that it effects a fastening of the end-side adapter or the longitudinal carrier to the lower end of the respective side part as much as possible, so that the longitudinal carrier, the end-side adapter or the transverse carrier ends with its lower end together with the lower edge of the side part. The functional fitting can also be used in this way with a bed with a substructure or a bed or a frame which is placed on the ground or arranged, for example, under a drawer. It is important that the functional fittings do not protrude from the lower edge of the bed frame.

In addition, however, the invention also includes a box spring bed comprising: a bed frame having two frame side portions extending in a longitudinal axis of the bed and head and foot frame portions extending laterally across a width of the bed at a head end and a foot end; a middle plate extending between the side portions in a lying plane; a head plate swingably connected to the intermediate plate about a head plate swing axis extending transversely to the longitudinal axis of the bed at a head end of the intermediate plate; and a foot plate swingably connected with the intermediate plate at a foot end about a foot plate longitudinal axis extending transversely to the bed longitudinal axis. According to the invention, the box spring bed has the aforementioned functional accessories.

Detailed Description

According to the figures, two functional accessories 2,4, which are generally arranged coaxially along the central longitudinal axis of the bed frame 6, are fitted in the lower part and inside of the bed frame 6 for a box spring bed.

The box spring bed, more particularly its bed frame 6, comprises: two frame side sections 6.1,6.2 which extend parallel to one another and are spaced apart from one another uniformly in the transverse direction parallel to a longitudinal axis extending centrally between them; and a head frame part 6.3 and a foot frame part 6.4 extending transversely between and connecting the frame side parts 6.1,6.2 at the head and foot ends, thereby constituting a circumferentially closed, rectangular bed frame 6.

An intermediate plate 8 is fastened to the upper side of the bed frame 6, extending transversely between the frame side parts 6.1,6.2 approximately in the middle. The intermediate plate 8 defines a lying plane of the bed, which in the mounted position preferably extends in a horizontal plane. On the intermediate plate, a head plate 12 is pivotally fastened at the head end and a foot plate 14 is pivotally fastened at the foot end by means of a hinge 10. The intermediate plate 8, the head plate 12 and the foot plate are designed as transparent plastic glazing panels for better illustration of the components, but in practice are designed more precisely as wood panels.

The foot plate 14 is also divided into an upper support plate 14.1, which faces the intermediate plate 8, and a longer lower support plate 14.2, which faces away from the intermediate plate. The upper support plate 14.1 and the lower support plate 14.2 are in turn connected to one another in a pivotable manner by means of a hinge 10.

Fig. 2 shows the headboard 12 and footboard 14 respectively in a raised, i.e. raised from a lowered initial position, curved position. Whereas in the initial position the head plate 12 and the foot plate 14 extend parallel to the intermediate plate 8 and thus define a lying plane together with said intermediate plate 8.

Each functional fitting 2,4 comprises a longitudinal carrier 2.1,4.1 of rectangular steel profile, which is mostly made of painted steel and extends centrally underneath the bed frame 6 on the bed longitudinal axis. On the respective outer end sides of the longitudinal carriers, fitting corners 2.2,4.2 are fixed, which are arranged to the upper side of a transverse carrier 6.5,6.6, which is fixed laterally between the side parts 6.1,6.2 and on the inside on the head frame part 6.3 and the foot frame part 6.4, which fitting corners each have a horizontal leg resting on the upper side of the transverse carrier 6.5,6.6 and a vertical leg resting on the inside of the transverse carrier.

On the inner end face of the longitudinal support 2.1,4.1, corner piece profiles 2.3,4.3 are fastened, which extend on both sides of the end face in each case transversely to the longitudinal axis of the longitudinal support, whose inner legs are fastened laterally to the longitudinal support 2.1,4.1 and whose horizontal mounting legs extend transversely to the longitudinal axis of the longitudinal support 2.1,4.1 and can be screwed in the installed position to the underside of the intermediate plate in order to thereby connect the functional fittings 2,4 on the one hand on the inside to the bed frame 6 and at the same time to protect the intermediate plate 8 centrally from buckling, for which purpose the corner piece profiles 2.3,4.3 are preferably configured as steel profiles. For stability reasons, the entire functional fitting 2,4 consists of a bent or stretched steel profile.

At the outer ends of the functional fittings 2,4, the rear motor ends of the linear drives 2.4,4.4 are each rotatably hinged to the outer and lower ends of the longitudinal carriers 2.1,4.1. The inner end of the linear drive 2.4,4.4, which is formed by a lifting tube that can be adjusted by an electric motor, is rotatably articulated to the transverse bar of the lifting support 2.5,4.5.

Each stand 2.5,4.5 is rotatably fixed at its lower end to the longitudinal carrier 2.1,4.1 and widened in the transverse direction at its upper end to increase the contact surface under the headboard 12 and footboard 14 or lower support plate 14.2.

Each lifting support 2.5,4.5 can be formed from two profile corner pieces connected to one another, which have a lower fastening end for lateral articulation on the respective longitudinal support 2.1,4.1, i.e. are surrounded on both sides by a shaft arranged therebetween and extend from the lower fastening end in the longitudinal direction parallel to one another on both sides of the longitudinal support 2.1,4.1, in the longitudinal direction first transitioning into a widened region in which the distance from the profile corner pieces widens and at the free upper end of the profile corner pieces again transition into end sections extending parallel to one another.

The stand 2.5 is provided with rollers at the free upper end at end sections spaced apart from each other in the transverse direction, which rollers roll on the underside of the head plate 12 when the stand 2.5 is adjusted from the lowered initial position into the raised lifting position. The lifting tube of the linear drive 2.4 engages with a transverse carrier which extends between the widened sections of the two profiles of the standing bracket 2.5.

The standing bracket 4.5 is constructed similarly to the standing bracket for the head part at the foot part, with the difference that instead of the roller, it has two corner piece profiles on the end section, which are screwed on the underside of the lower support plate 14.2. The lifting tube of the linear drive 4.4 is in turn coupled to a fork-shaped joint which is fastened to a transverse carrier which extends between the widened sections of the two profiles of the standing bracket 4.5.

According to the invention, the functional units 2,4 are expediently configured such that the linear drive is fastened with its lower motor end on the outside as far as possible in the installed position of the assembly bed frame 6, i.e. is articulated on the longitudinal support 2.1,4.1, and the relatively movable lifting tube is rotatably coupled at its upper end as far as possible to a lifting support 2.5,4.5 which is articulated inwardly with its lower fixed end rotatably oriented on the longitudinal support 2.1,4.1, in order to thereby achieve an optimal force expansion and to have to be provided with as little motor power as possible.

Fig. 4 shows the functional fitting in a perspective front view in the lifted position, that is to say in which the lifting bracket 2.5 forms an angle of approximately 45 ° with the longitudinal axis of the longitudinal carrier 2.1, that is to say is lifted by the linear drive 2.4.

In fig. 5, the functional fitting 2 is mounted below the head end of the bed frame 6 and is thereby screwed on the inside to the underside of the intermediate plate 8 by means of corner piece profiles 2.3 and is fastened on the outside end side by corner piece profiles, which are formed correspondingly and welded on the end side to the longitudinal support 2.1, together with the inner edge, which serve as frame fastening sections and comprise upper support legs, which extend in the horizontal plane in the installed position, and contact legs, which form a right angle with this support legs, and which contact on the inside against the inner end face of the transverse support 6.5. That is, in the assembled condition in fig. 5, the lower end of the longitudinal carrier 2.1 of the functional accessory 2 ends together with the lower edge of the bed frame 6.

Fig. 6 shows a perspective front view of an alternative embodiment of the functional fitting according to fig. 4 and 5 fitted on the bed frame 6. The functional fitting differs in that instead of the fitting corner pieces 2.3 on the inner end face of the longitudinal carrier 2.1, for example, the longitudinal carrier 2.1 is provided with a transverse carrier 2.6 of rectangular hollow profile, which is screwed to the underside of the intermediate plate 8 and thereby additionally stabilizes the intermediate plate 8 against buckling.

Fig. 7 shows in turn a perspective front view of a further embodiment of the functional fitting 2 according to the invention fitted in the bed frame 6. In this embodiment, the transverse carrier 2.7, which is likewise embodied here as a rectangular profile, is matched to the rectangular profile of the longitudinal carrier 2.1 and welded to the longitudinal carrier 2.1 at its inner end face, extending transversely to the longitudinal axis of the longitudinal carrier 2.1. In an alternative embodiment, the transverse carrier 2.7 is connected fixedly but releasably to the inner end face of the longitudinal carrier 2.1, wherein the connection is achieved by a screw connection or plug connection to the fastening element. The transverse carrier 2.7 extends between the inner sides of the frame-side sections 6.1,6.2 and is screwed with end-side flanges to the inner sides of the frame-side sections 6.1,6.2 in such a way that it ends with the lower end of the bed frame 6.

Fig. 8 shows a perspective front view of a further embodiment of the functional fitting 2 fitted in the bed frame 6, which differs from the embodiment according to fig. 7 in that the transverse carrier 2.8 is constructed shorter than the clear distance between the inner sides of the frame side sections 6.1,6.2, and that an end-side adapter 2.9, which has a fitting flange as a frame fastening section for fitting on the inner sides on the frame side sections 6.1,6.2 and accordingly comprises a rectangular profile as a longitudinal carrier fastening section, which is constructed complementarily to the transverse carrier 2.8, is insertable into the transverse carrier 2.8 and adjustable relative thereto, is inserted into the transverse carrier 2.8.

Fig. 9 also shows a perspective front view of a further embodiment of the functional fitting 2 fitted in the bed frame 6.

This further embodiment differs from the embodiment shown in fig. 5 in that no transverse carrier 6.5 is provided on the inner side of the head frame part 6.3 of the bed frame 6. Instead, the end-side adapter 2.10 is inserted into the outer end side of the longitudinal carrier 2.1 and can be adjusted relative to the outer end side.

Fig. 10 shows an enlarged perspective front view of the end adapter 2.10 in isolation. The end-side adapter therefore comprises a longitudinal carrier fastening section embodied as an insert part 2.10.1 and a mounting flange 2.10.2 embodied on the outer end side of the insert part 2.10.1, that is to say which can be inserted into the end side of the longitudinal carrier 2.1 and which is screwed on the inside to the head-frame-side part 6.3.

Fig. 11 shows a further embodiment of an adaptively designed functional fitting 2 fitted in a bed frame 6 in a perspective front view. The adaptive design is achieved here by differently configured end-side adapters 2.11, which are shown in fig. 12 in a perspective enlarged front view. The end-side adapter further comprises: the insertion part, which is designed as an insertion profile 2.11.1, i.e. which is adapted to the internal structure of the longitudinal support 2.1, is inserted into the latter so as to be able to move relative to each other; and a support corner piece 2.11.2, which is arranged on the outer end face of the insertion profile 2.11.1 and is designed to rest on the inside on the inner edge of the transverse carrier 6.5 and to this end comprises an upper support leg and a rest leg, between which a right angle is formed, that is to say which matches the inner edge of the transverse carrier 6.5.

The end adapters 2.10 and 2.11 according to the embodiment in fig. 10 and 12 are composed of plastic and are produced by injection molding.

The figures below now each show an enlarged view of the respective outer end face region of different embodiments of the functional fitting, with a fixing corner piece 2.12, which is welded laterally to the longitudinal carrier 2.1 in different positions spaced apart from the end face of the longitudinal carrier 2.1.

The fixing angle 2.12 is formed as a steel profile with a U-shaped cross section, which has an inner leg 2.12.1 which is fixed, in particular welded, to the longitudinal support 2.1 and which in this respect rests on the outside of the longitudinal support, from which the transverse leg 2.12.2 extends at an angle of 90 degrees from the plane of the inner leg 2.12.1. An outer leg 2.12.3 is provided at the outer end of the transverse leg 2.12.2, which in turn forms an angle of 90 degrees with the plane of the transverse leg 2.12.2 and furthermore extends parallel to the inner leg. Holes 2.12.4 are formed in the outer leg 2.12.3.

In the embodiment according to fig. 13, the fixing corner piece 2.12 is fixed to the distal, outer end face of the longitudinal support 2.1 in such a way that the transverse leg 2.12.2 ends together with the outer end face of the longitudinal support 2.1 and with the aid of the contact leg of the support corner piece of the end-side adapter, the contact leg is brought into contact with the inserted end-side adapter 2.13 according to the illustration in fig. 14.

Fig. 13 shows an enlarged perspective front view of an embodiment of an end-side adapter 2.13, which in turn has an insertion profile 2.13.1 designed for insertion into the end side of the longitudinal carrier 2.1 and a support corner piece 2.13.2 fastened to the outer end side of the insertion profile 2.13.1, which is designed for supporting onto the inner edge of the transverse carrier 6.5 or 6.6, in this case has a longer, horizontally extending support leg and an abutment leg which is designed approximately equally or more widely and which in turn extends at right angles to the support leg.

This end-side adapter 2.13 is shown in a perspective front view according to fig. 14, which is inserted into the end side of the longitudinal carrier 2.1. The positioning holes 2.15 are formed at defined distances extending transversely to the insert profile 2.13.1.

The embodiment is also adapted to the design, for which purpose the insert profile 2.13.1 can be fixed in different positions in the received longitudinal support 2.1 by means of the insert sleeve 24 and the fixing pin 26, which can be inserted into the insert bore 2.14 in the longitudinal support 2.1 and then through the corresponding positioning bore 2.15 in the insert profile of the end adapter 2.13, and which insert profile is thereby fixed in different, nevertheless defined positions in accordance with the standardized bed dimensions. The securing sleeve 16 can be inserted into the insertion opening 2.14, which can be secured by means of the securing pin 18 and secures the end adapter 2.13 in the longitudinal support 2.1 in different defined positions.

The embodiment in fig. 15 and 16 differs from the embodiment in fig. 13 and 14 only in that the end-side adapter 2.16 is designed for fastening to the inner side of the head frame part 6.3 or the foot frame part 6.4, i.e. instead of the support corner piece, has a mounting flange 2.16.2 welded to the end side of the insert profile 2.16.1.

In the embodiment according to fig. 17, the end-side adapter 2.17 is configured for fixing on the inner side of the head frame part 6.3 or the foot frame part 6.4 in an adaptive manner, wherein the support corner piece 2.17.2 in turn comprises a shorter support leg and a longer abutment leg for supporting on the upper edge of the frame 6 in order to position the functional fitting 2 as far as possible on the lower end of the frame 6 in the installed position.

Fig. 19 to 27 show a functional fitting of non-adaptive design, in which the respective frame fastening element or frame fastening section is welded fixedly to the respective end face of the longitudinal carrier 2.1. Furthermore, for rotatably fixing the lifting support 2.5 or the linear drive 2.4, the fixing angle 2.12 is arranged on the side of the longitudinal support 2.1.

The functional fitting 2 has longitudinal supports 2.1 of different lengths for beds of different lengths, wherein, in other words, the respective fixing corner pieces 2.12 are arranged relatively always on the same location relative to the corresponding fixing corner pieces for the lifting support at the opposite ends (not shown), and the length of the longitudinal supports 2.1 is designed longer in this respect.

In the embodiment according to fig. 19, the fixing corner piece 2.12 is thus positioned on the inner side of the bearing corner piece against the edge foot on the outermost end side of the longitudinal carrier 2.1.

Fig. 20 shows the same embodiment for a longer bed, that is to say, in which the longitudinal support 2.1 is embodied with a length of 5cm, so that there is a distance between the lateral leg 2.12.2 of the fixing corner 2.12 and the contact leg of the end-side support corner.

Fig. 21 shows the embodiment according to fig. 20 for a bed length of 2.20m, however, wherein the distance between the fixing corner pieces 2.12 and the support corner pieces on the end side of the longitudinal carrier 2.1 is now 10cm.

Fig. 22 to 24 show the same illustrations as fig. 19 to 21, with the following differences: in this embodiment, the frame fastening element is embodied as a mounting flange 2.18 which is welded to the outer end face of the longitudinal carrier 2.1 transversely to the longitudinal axis of the longitudinal carrier and can be screwed to the inner side of the head frame part 6.3 or the foot frame part 6.4 by means of bolts. The longitudinal supports 2.1 are again provided in different lengths corresponding to the bed length, so that there are different distances between the outer end sides with the mounting flanges and the lateral legs 2.12.2 of the fixing corner pieces 2.12.

Fig. 25 to 27 then show a non-adaptive embodiment of the functional fitting 2, but here, however, the frame fastening elements are embodied as support angles 2.19, i.e. they are in turn embodied for resting against the inner side of the head frame part 6.3 or the foot frame part 6.4 of the bed frame 6, i.e. they are embodied for fastening on the inner side of the frame 6 on the end side, but are in turn adapted to beds of different lengths by means of fastening angles 2.12 which are positioned in different positions relative to the outer end side.
