EP3031362B1 - Bed frame with adjustable slats in a horizontal plane - Google Patents

Description

The invention relates to a bed frame with adjustable in a horizontal plane spring strips and a suitable fitting for a bed frame formed from the lying surface according to the preamble of claim

The term "bed frame" is understood according to the invention, any arrangement of a sitting or lying surface whose support surface is formed from spaced spring strips. Including therefore also slatted frames with spring-mounted in the vertical direction slats or solid frame in which the slats are arranged unsprung.

For lying areas for beds, sofas, seating, there is a need to move the seat cushion or mattress-bearing slats in the horizontal direction.

Such a lying surface is already known and relates to spring strips which are mounted in the horizontal direction over a short displacement area slidably mounted on a slatted frame.

In known manner, therefore, each spring bar is mounted frontally in a storage element, which in turn is fixedly and immovably disposed on the longitudinal spar of a bed frame or a slatted frame.

This makes it possible to carry out a horizontal adjustment of the spring bar in the storage element itself without moving the storage element in the longitudinal direction to the longitudinal spar and set.

This results in the disadvantage that a setting of the spring strips is given only by a range of 2 cm. Thus, the mutual distance of the slats in a slatted frame or a bed frame can be adjusted only slightly.

The EP 0 141 260 A2 shows a bed frame with adjustable in a horizontal plane spring strips and bearing elements for supporting the ends of the spring strips on a longitudinal spar of the bed frame, wherein the bearing element over any shift length thereby along the Längsholmes is displaceable, that the bearing element consists of a respective end of the spring bar female housing in which at least one manually operable, spring-loaded by a bending spring locking device is arranged, which engages in associated receiving profiles in the longitudinal direction of the longitudinal spar and is locked there. This locking device can be disengaged by lifting in the vertical direction against the spring force of the bending springs.

A disadvantage of this device, however, is that it is not secured against shear forces acting in the direction of the longitudinal spar or at a shallow angle in the direction of the longitudinal spar.

The invention is therefore the object of developing a horizontal adjustment and determination of slats in a slatted frame and / or bed frame of the type mentioned so that an adjustment of the horizontal distance of the slats in a much larger displacement area and with a hedge against acting in the longitudinal direction Displacement forces can take place.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that the respective end face of the spring bar receiving bearing element is displaceable and lockable in the horizontal direction over any displacement along the longitudinal spar of the bed frame.

With the given technical teaching, the advantage is achieved that now each spring bar individually in relation to the adjacent spring strip over an arbitrarily large adjustment along the longitudinal axis of the longitudinal spar of Bed frame is designed adjustable and lockable, because the storage element for receiving the spring bar itself forms the adjusting body.

Thus, the invention provides that all bearing elements, which carry the spring strips, in the direction of the longitudinal beams of the bed frame and / or slatted frame slidably adjustable over any displacement and are detectable.

Under a bearing element according to the present invention is understood to be a complex bearing body having spring elements, which may be arbitrarily formed.

Such spring elements may be elastomer springs or otherwise sprung elements which are capable of resiliently supporting the respective end face of the spring strip in the vertical direction.

According to a development of the invention, however, it may also be provided in another embodiment that such spring elements completely eliminated.

Furthermore, it can be provided in another embodiment of the invention, that in each case an additional height adjustment device can be arranged on the bearing elements for receiving the end faces of the spring strips. In this case, it is provided that not only the end faces of the spring strips on the displacement of the bearing elements in the horizontal direction are displaceable, but that in the storage element even height adjustment devices are available, so that the height of the spring strips on the storage element is still adjustable and lockable ,

However, the invention is not dependent on such Höheneinstellvorrichtung. It can also be omitted.

It is only important that the spring strips are adjustable and detectable even in any adjustment in the direction of the longitudinal spar of the respective slatted frame and / or bed frame, so that now for the first time there is the possibility of using different mutually spaced slats different lying areas on the bed define.

In this way, by a free displacement of spring strips z. B. a group-wise arrangement of such slats are provided, at the points of the bed, where maximum support of the body of a user lying on it is required. For example, it is possible to collapse the spring strips so that in the lumbar region there is a very high density of spring strips arranged there, while around the lumbar area (up and down) no spring strips must be arranged or another spacing is provided.

The division of the lying surface with differently grouped spring strips, which are free and long of the longitudinal Holmes the lying surface displaced and lockable, was previously unknown. For this reason, the invention provides a variety of ways in which such a shift of slats can take place in the area of the bed.

The term "lying surface" is understood to mean all lying surfaces of upholstered furniture, seating or sleeping furniture that are able to support a cushion. The invention is therefore not dependent on the spring strips are part of a slatted frame. You can attack with their storage elements according to the invention also directly to the longitudinal beams of a bed frame, in which case a slatted frame would be omitted.

In a preferred embodiment of the present invention, it is provided that the storage elements according to the invention for holding the spring strips, which are adjustable and lockable in the longitudinal direction of the longitudinal beams, in the transverse direction to the longitudinal axis in an undercut groove in the longitudinal spar can be latched, so that it is not necessary, this Insert storage elements in the direction of the longitudinal groove in the longitudinal spar one after the other, but they can be clipped in the direction perpendicular to the longitudinal groove in the longitudinal groove.

Thus, there is the advantage that even with a ready equipped slatted frame or a bed frame can still be clipped later in the longitudinal groove in the longitudinal beam additional storage elements that are suitable for receiving additional slats.

Thus, thus, the spring bar density, d. H. So the number of slats in the slatted frame or bed frame can be easily increased or decreased. Thus, the load capacity of the slatted frame or the bed frame can be changed in any way by adding or removing spring slats and associated storage elements also at a ready equipped bed frame or slatted frame.

In a preferred embodiment of the invention, it is provided that the bearing element according to the invention consists essentially of a housing in which two directed in the opposite direction locking latch are present, which are spring loaded in engagement with an associated locking rail, which locking rail in a longitudinal groove on the inside is attached to the longitudinal spar of the slatted base.

For ease of description, it is assumed in the following description and accordingly also in the following description of the drawing of a fitted with slats slatted, although the invention is not limited thereto.

As stated above, the slatted frame can also be completely eliminated and the storage elements according to the invention could be arranged directly in the longitudinal beams of a bed frame. Only for the sake of simpler description it is assumed that the fitting of a slatted frame with slats, although the invention is not limited thereto.

In a preferred embodiment of the invention, it is accordingly provided that the latching bolts necessary for longitudinal adjustment and detection engage in a spring-loaded manner in assigned receiving profiles in the longitudinal direction of the longitudinal beam. In a first embodiment of the invention, it is provided that this receiving profile is formed as in the longitudinal direction over the entire length of the longitudinal spar extending locking rail, which carries an associated toothing.

In another embodiment of the invention, it may be provided that the locking rail is replaced by a perforated rail, and in a third embodiment of the invention can be provided that the locking rail is not arranged in an undercut groove in the hollow profile of the longitudinal spar, but as an insert rail is trained.

It can also be provided in another embodiment that the longitudinal spar consists of a deformable metal profile, in particular an aluminum profile, and that such a locking rail is arranged in the form of indentations in the longitudinal direction of the longitudinal spar.

Instead of attaching a toothing and perforated profiles can be used, which are either introduced directly in a profile of a longitudinal spar or used later as an insert rail.

In a further embodiment, it may be provided that instead of two oppositely arranged and spring-loaded locking latch now a locking comb is provided which carries a plurality of locking elements, which can be brought in the longitudinal engagement of the longitudinal spar in the optional engagement with the counter profile.

Instead of a spring-loaded engagement of the previously described locking elements and locking devices can be used, the z. B. according to the screw principle, the clamping principle or other access and Wegstellmechanismen work.

It may be provided that wedge profiles are used to achieve a clamping engagement between the bearing element and the associated profile on the spar side of the slatted base instead of a gear engagement.
Thus, it can be stated that instead of a latching engagement, which is spring-loaded or mechanically achieved by clamping elements, a clamping engagement is also included according to the invention.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following, the invention will be explained in more detail with reference to drawings illustrating several execution paths. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In FIGS. 1 and 2 is generally a lying surface 1 shown schematically, which is designed either as a bed frame 2 or slatted frame 3, wherein in the latter case the slatted frame 3 would be used in a bed frame 2, not shown.

In the illustrated embodiment, it is assumed that it is a slatted frame 3, which is used in a bed frame 2, not shown.

Here it can be seen that a number of spring strips are used 4-7 at an arbitrary distance 18 in the slatted base 3 and that the mutual horizontal distance of the spring strips 4-7 in the arrow directions 11, 12 in any manner and in any area adjustable to each other and is detectable.

The slatted frame 3 consists in a conventional manner of two mutually parallel transverse bars 8, which are interconnected by two mutually parallel longitudinal beams 9. It can consist of any material, such. As a metal profile, a wooden profile, a plastic profile or the like.

It is important that the respective spring strips 4-7 are accommodated on their end faces in bearing elements 20 and these bearing elements 20 in an associated longitudinal groove on the inside of the longitudinal members 9 in the direction of arrow 11, 12 are displaceable and lockable.

As a first embodiment shows the FIG. 1 in that the longitudinal groove can be formed on the inside of the longitudinal member 9 as a latching rail 10, which has a very fine latching division, the z. B. may be in the range between 1 to 3 mm. This means that in the range of 1 to 3 mm each spring bar in the arrow directions 11, 12 is adjustable and lockable.

On the left side of the longitudinal spar 9 and on the opposite side of the longitudinal spar 9 equal displacement distances are provided, so z. B. on the top of each longitudinal spar 9, a scale is mounted so that each storage element 20 each side can be adjusted to the respective longitudinal beam 9 to the same displacement position.

It is a scaling, which is arranged as a scale once on the storage element and which can be brought in a specific comparison to an associated scale on the top of the longitudinal spar 9.

The FIG. 1 shows as a further embodiment that the invention can still provide a height adjustment 19 of the spring strips 4-7, said height adjustment will be described later in the manner of a height adjustment plate 28.

As already stated in the general description part, this height adjustment 19 can be completely eliminated, and it can remain in the horizontal direction in the arrow directions 11, 12.

Another important feature of the invention is that the storage elements in the direction of arrows 64 in an associated retaining groove in the region of the longitudinal spar 9 are clipped, at any time - even with a fully equipped with slats slatted frame 3 - even more storage elements 20 each directed in the direction of arrows 64 are clipped into the longitudinal groove in the region of the longitudinal spar and can be equipped with additional spring strips.

In this way, the number of slats per couch surface 1 can be set in any way.

The FIG. 2 shows only roughly schematically that at the desired body support points a person 13 may be provided a different density and a different distance from slats.

It is shown schematically that, for example, in the head region 14, only a small number of spring strips is present, while in the shoulder region 15 a smaller number of spring strips 6 and 16 in the lumbar region a larger number of spring strips 5, is provided at a shorter distance, while in the foot area 17th a smaller number of spring strips 4 is provided at a greater distance.
In this way, both the number of spring strips 4-7 and their mutual distance freely on the bed 1 can be made adjustable.

In a first preferred embodiment, the longitudinal spar 9 of the slatted base 3 is made of an aluminum hollow profile 21, which on its inner side has an undercut receiving profile 22 into which the latching rail 10 is inserted ( FIG. 5 ).

The support member 26 is preferably made of a plastic housing 39, which is hollow profiled and which laterally beyond the housing side walls beyond standing spacers 31, behind which (in FIG. 3 not visible), the associated locking latch 32 are arranged, which are provided in engagement with the longitudinal spar-side locking rail 10.

The FIGS. 3 to 5 also show that according to the invention, this housing 39 is clipped into the undercut receiving profile 22 of the longitudinal spar 9 and is held there by latching hooks 23, which engage behind the undercuts of the receiving profile 22 and thus ensure a longitudinal displacement in the directions of arrows 11 and 12, but only one Engaging in the direction of arrow 64 (see FIG. 1 ), but not a repeated disengagement in the opposite direction to the arrow 64th

Thus, each storage element 20 can be clipped in the direction of arrow 64 in the receiving profile 22 in the region of the longitudinal spar 9, but can then be removed only in the direction of arrow 11 or 12 from the receiving profile 22.

The representation in FIGS. 3 to 5 further shows that to the storage element 20 still a height adjustment plate 28 is included, which allows a height adjustment of the spring elements 25 in relation to the support member 20 in the direction of arrows 19.

Each spring element 25 consists of two spaced-apart and identically designed spring bodies, which are molded down over arcuate spring body 27 on a plate whose plate forms receiving openings for two superimposed and mutually parallel retaining pin 30.

The retaining pins 30 are molded onto a height adjustment plate 28, which can be inserted in the manner of a vertically directed insertion guide behind the detent plate 26 for the bearing element 20.

The height adjustment plate 28 is moved to a locking part 29 on the locking plate 26 of the support member 20 adjustable in height and fixed with the locking part 20.

As already stated, the height adjustment in the direction of arrows 19 for the spring strips is not essential to the invention, but can be additionally provided.

The FIGS. 7 and 8 show the clips detent 24 of the bearing element 23 so that a latching in the direction of arrow 64 of the bearing element 20 in the undercut receiving profile 22 is possible.

This clips detent 24 is formed by a plurality of spaced-apart resiliently formed latching hooks 23, which in associated Undercuts of the receiving profile 22 intervene, as in FIG. 5 is shown.

The FIGS. 7 and 8 further show that the detent plate 26 is part of a plastic housing 39 which defines the bearing element 20.

Furthermore, the show FIGS. 7 and 8 the two oppositely directed latching bolt 32, the spring-loaded in engagement with the associated toothing of the locking rail 10 are held.

The disengagement takes place by pressing an in FIG. 9 illustrated handle 34.

It must therefore be operated with the fingers of one hand both the one handle 34 and the other handle to bring both locking latch 32 except the spring-loaded engagement with the locking rail 10.

The oppositely directed locking the latching bolt 32 serves to prevent that in the locked state, the storage element 20 can be moved in the direction of arrow 10 or 11 unintentionally.

However, if only one locking bolt 32 is actuated by actuation of a handle 34, the bearing element 20 can according to FIG. 9 Although moved in one direction, but not in the other direction.

The oppositely directed spacers 31 serve for a stop limit of adjacent storage elements 20. If adjacent storage elements 20 are pushed close to each other, touch their spacers 31 each other and thus form a shift limit.

The FIG. 9 shows in an exploded view of the structure of the storage element 20 according to the invention, wherein the locking member 29 is used for the height adjustment, so that the height of the Höheneinstellplatte 28 in the Insertion guide 65 in the region of the bearing element 20 is adjustable and lockable.

It is also out FIG. 9 removable, that the two latching bolt 32 are each formed the same and each latching bolt 32 is rotatably connected to a shaft 35, at the top free end, the handle 34 is rotatably mounted.

The shaft 35 carries at the bottom a bearing pin 36 and the entire element with the locking latch 32, the handle 34 and the shaft 35 is inserted into a cavity of the housing 39 of the bearing element 20, and arranged in a housing compression spring 38 engages in a receptacle 37th at the back of the handle 34, this biases spring-loaded, so that the locking latch 32 associated therewith spring-loaded comes into engagement with the toothing of the locking rail 10 and remains there as long as the handle 34 is not actuated.

The pivoting of the shaft 35 thus takes place in the direction of arrow 33rd

The FIG. 9 also shows that the entire spring element 25 can be plugged into the retaining pin 30 of the bearing element 20 in two different height-adjustable layers (Höheneinstellvorrichtung 19).

Either engage both retaining pin 30 in the superimposed receiving spaces 40 on the spring element 25 or the spring element is set by one step up, so that only the upper retaining pin 30 engages in the lower receiving space 40, for example.

The shape of the retaining pin 30 is selected so that a positive engagement is ensured in the associated receiving spaces 40 on the spring element 25, so that they are tilt-mounted on the bearing element 20 and the upper pin does not block the compression of the spring element.

The FIGS. 10 to 12 show as a modification, the attachment of a separate locking rail 10 in an undercut receiving profile 22 of a longitudinal spar 9 now that in the metal profile of the longitudinal spar 9, a stamping profile 41 can be impressed as a tooth profile. There are thus achieved the same features as in relation to the previous locking rail 10.

The FIGS. 13 to 15 show as a further embodiment in a longitudinal profile in the region of the longitudinal beam an insertion profile 42, which can also be inserted and attached separately as a tooth profile.

The FIGS. 16 and 17 show that on the inside of the longitudinal spar 9, a hole profile 43 can be incorporated directly into the material of the longitudinal spar 9, while the FIGS. 18 and 19 show that even in a separate groove such a perforated profile 43 can be inserted and secured as insert profile 42.

The FIGS. 20 to 22 show an opposite to the previously described locking bars 32 modified embodiment in which the latching bars 32 are replaced by a locking comb 45 which cooperates with an associated toothed flat profile 44.

If the latching comb 45 is lifted out of the toothing of the flat profile 44 in the direction of the arrow 46, then the entire support element, which is connected to the latching comb 45, can be displaced in the direction of the arrows 11, 12 along the longitudinal beam 9. If the locking comb, however, in the direction of arrow 46 with its teeth 47 with the teeth of the flat profile 44 is engaged, then a lock in the direction of arrows 11, 12 is given.

The FIGS. 23 and 24 show a turn modified embodiment in which it can be seen that a locking comb 45 can be brought in the horizontal direction in engagement with the tooth profile of the locking rail 10. For this purpose, an actuating bar 49 is provided which actuates the locking comb 45 behind a cover 48 so that it can be selectively engaged in the direction of arrow 66 in the tooth profile of the locking rail 10 or alternatively in the opposite direction to the indicated arrow 66 can be disengaged. Again, that is Storage element 20 in its formation as a detent plate with its housing 39 in the arrow directions 11, 12 slidably and lockable.

The FIGS. 25 to 27 show a modified embodiment, in which it can be seen that a latching rail may have top and bottom rows of teeth 50a, 50b and each row of teeth associated with an associated actuating bar 49, the spring-loaded selectively in the engaged position or against the spring load in disengaged position from the row of teeth 50a, 50b can be brought.

A modified embodiment is again in the FIGS. 28 to 30 shown where a clamping engagement is shown instead of a tooth engagement.

The local detent plate 26 of the bearing element 20 consists of two oppositely arranged clamping jaws 54, which are each displaceable and lockable on a longitudinal spar, wherein the longitudinal spar is formed as a prismatic guide 51.

The clamping can optionally be brought about or canceled by an actuating button 52. The actuator button may act spring loaded on the jaws 54; However, it can also be designed as a screw or the like.

It is also possible to use an eccentric clamping button instead of a screwable or pushable actuating button 52.

The FIGS. 31 to 33 show as another embodiment, in turn, the formation of the longitudinal spar 9 as a polygonal profile 56, wherein the clamping of the bearing element 20 takes place on a profile leg 57 and the clamping takes place here by an actuating knob 52 which is either spring-loaded or mechanically pressed on the profile leg 57.

The FIGS. 34 to 36 show a polygonal profile 58, which in the manner of the previously described embodiment has a latching rail 10, wherein the Storage element 20 with its housing 39 has a rotatably mounted gear 59, which is in meshing engagement with the locking rail 10. The rotation of the gear 59 in the direction of arrow 61 and in the opposite direction can be locked by an actuating button 60, so that in any shift position upon actuation of the confirmation button 60, the storage element 20 can be moved in the direction of arrows 11, 12 along the longitudinal spar 9.

The actuation of the actuating button 60 can either be spring loaded or mechanically provided as a screw or clamping element.

The rotation of the gear 59 takes place in the axis of rotation 62 according to FIG. 36 which is merely hinted at.

Out FIG. 4 It can also be seen that a scaling 63 can be attached to the bearing element 20, which can be brought into conformity with a scaling, not shown, on the side of the longitudinal beam 9. In this way, the left and right sides of mating bearing elements 20 can always be anchored at the same location on the longitudinal spar 9.
