Description

The invention relates to a bed, in particular in the embodiment as a hospital and / or nursing bed, with a longitudinally extendable bed frame, which has two longitudinally extending spars, which are telescopically formed and each have an outer frame and an inner frame, wherein the outer frames each provide a cavity which receives the associated inner frame longitudinally displaceable.

Beds in general, as well as hospital and / or nursing beds in particular, are well known in the art. They typically have a bed frame which is designed in the manner of a frame and serves to receive a lying surface element, for example a slatted frame. The lying surface element in turn serves in turn to support a mattress, a cushion element and / or the like. There are also known from the prior art constructions, according to which a lying surface element is received with the interposition of an inner frame of the bed frame.

A previously known from the prior art bed frame has two longitudinally extending spars, which are connected at one end as the other end via cross member, whereby the frame-like design of the bed frame results. In this case, it may be a cross member to a plate-shaped bed head, which is bolted to the coupled thereto spars, for example. Such a construction is for example from the EP 2 364 685 A1 known.

A bed frame is typically in its geometric configuration dimensioned to accommodate the inclusion of size-standardized mattresses, cushioning elements and / or the like. A common dimension in the longitudinal direction is 2,000 mm. This size configuration is usually sufficient. In the case of persons who have grown too large, however, such an extent in the longitudinal direction is not sufficient and there is a loss of comfort, in particular if the crossbeams interconnecting the spars are in the form of plate-shaped bed heads. Under certain circumstances, a person lying in bed may then no longer be able to stretch out as desired, since it bumps either with his head on his head or his feet on his foot. Especially in the health and care sector, this impairment is disadvantageous because certain recovery and / or nursing care may require certain sleep and / or rest positions of the person lying in bed.

To be able to provide a sufficient bed comfort even comparatively tall people, beds have become known from the prior art, which have a retractable in length bed frame. The spars of such a bed frame are telescopically formed, so represent a pipe-in-pipe system, each rail an outer frame and an inner frame is provided. The outer frames each provide a cavity which receives the associated inner frames longitudinally displaceable. The outer frames on the one hand and the inner frames on the other hand each end of one of the bed heads, so that the distance between the Betthäuptern and thus the bed provided by the bed can be increased by the Innenzargen moved relative to the outer frames and pulled out of these.

In practice, a bedstead extension by 200 mm has been found to be sufficient. Thus, a bed formed in this way can be increased by 200 mm to 2,200 mm from a standard longitudinal extension of 2,000 mm.

The possibility of bed, that is bedstead extension brings a variety of succession problems with it. Thus, ready-to-use provision requires not only an extension of the bedstead. Also, the lying on the bed frame bed element requires a corresponding extension, otherwise the desired comfort can not be achieved. In the state of the art, specially designed mattress and / or upholstery elements are used for this purpose Insert, which are introduced into the resulting gap gap between the drawn-out bed main part on the one hand and the bed main-side end edge of a lying surface element. There is thus no extension of the lying surface element, but it is only closed in the extended state of the bed frame Spattlücke closed by a mattress and / or upholstery element, whereby the actually desired sleep comfort is not taken into account. Incidentally, the handling, in particular storage in the case of non-use of such additional mattress and / or upholstery elements consuming.

Another problem arises in the case of a side rail provided by the bed. This too is extended when the bed frame is extended. From the state of the art, it is known in this context that to exchange for a standard operation provided side rails against a matched to the dimensions of the extended bed frame side rails. This previously proposed solution is not satisfactory, since the assembly or disassembly effort is considerable and it also requires the storage of unused side rails.

To avoid the disadvantages described above, it is the object of the invention to provide a equipped with a bed extendable bed frame equipped bed, which allows a simplified handling and in particular can be converted to the extended or the retracted state of use with only a few simple steps.

To solve this problem, the invention proposes a bed of the type mentioned above, which is characterized by a Zargenaufsatz, which is designed to be arranged on a in the extended state of the bed frame from the cavity of an outer frame protruding extension portion of an inner frame, wherein the Zargenaufsatz at least bettgestellaußenseitig having an outer contour of the outer frame corresponding outer contour.

The bed according to the invention is characterized by a Zargenaufsatz. This Zargenaufsatz is designed to be placed on an inner frame and has an outer contour that corresponds to that of an outer frame.

In extended, that is extended state of the bed frame protrude from the Außenzargen recorded Innenzargen einendseitig out of the outer frames, which outstanding portion of the inner frames can be referred to as extension section. As a result, there is an unavoidable paragraph between the outer frame on the one hand and associated inner frame on the other. This transition is not only visually unsightly, it also represents a risk of injury in the case of a sharp-edged outer frame sales. The frame attachment proposed by the invention provides a remedy, each inner frame such a Zargenaufsatz is provided. This is placed in the extended state on the protruding from an outer frame extension portion of an inner frame and is equipped bettgestellaußenseitig with an outer contour similar to that of an outer frame. As a result, an optically uniform image is created, because the protruding from the outer frame inner frame is covered by the Zargenaufsatz so that it is no longer visible. Rather, it creates the visual impression of a total continuous longitudinal frame.

The Zargenaufsatz also proves to be advantageous in that he also serves to extend a recorded from the bed frame lying surface element. In the case of an extended bed frame results in a gap opening between the recorded from the bed frame lying surface element on the one hand and the extended bed head of the bed frame on the other. It is necessary to close this gap opening, for which purpose mattress and / or upholstery elements designed in particular in the prior art are used. With the construction according to the invention another approach is taken. Thereafter, it is envisaged that the pin attachment bed frame inside a support portion for receiving a (partial) lying surface element, in particular a slatted slat has. In their combination, the two bed frames provided for each bed frame thus provide two opposing support sections available, which serve the one-end and other end support of a (partial) lying surface element. It can be made possible in this way an extension of the lying surface element, such as the slatted frame, which advantageously allows the user-desired reclining comfort in the extended area of the bed frame.

It is known from the prior art to arrange functional elements on the bars of a bed frame. In this case, "functional elements" are to be understood as elements which offer a user additional functionalities and / or assistance. To in this context, for example, bedstead aids, stand-up aids, holders for remote controls, urine bags and / or the like, as well as post elements for receiving side rails spars of a side rail.

For the arrangement of such functional elements on the bars of the bed frame according to the invention preferably adapter elements are used. With the interposition of such an adapter element, a functional element can be arranged on a bedstead rail.

The provided according to the invention Zargenaufsatz it allows in an advantageous manner that a recorded by a spar of the bed frame adapter element can be positioned over the entire longitudinal extent of the bed frame at any point. This free position selection is possible, because it is provided according to the invention that the Zargenaufsatz at least bettgestellaußenseitig has an outer contour of the outer frame corresponding outer contour. Thus, an adapter element can also be arranged in such a region of a spar, which is covered in the extended state of the bed frame by a Zargenaufsatz. This embodiment is particularly in combination with supported by adapter elements post for receiving side rails of advantage. It then does not require a separate auxiliary construction for bridging a gap in the side rail, which can be adjusted in a solid bed frame.

The above-mentioned features of the bed according to the invention as a whole provide the synergetic effect that allows a simplified overall handling, which also offers, in contrast to the prior art extended functionalities. Thus, it is ensured with the invention provided for the invention Zargenaufsatz that the resulting in the extended state of the bed frame between inner frame and outer frame paragraph is covered, which is not only a visual enhancement but also minimizes the risk of injury, as a possibly sharp heel edge of the outer frame the frame attachment is hidden. Furthermore, the two provided each bed frame Zargenaufsätze an abutment for a (partial) lying surface element, so that in the extended state of the bed frame in a simple manner an extension of the bed frame received lying surface element is reached. In addition, it is advantageous that functional elements not only in the area of the outer frames, but also in the extended area of the bed frame, that is in the field of Extension sections of the inner frames can be arranged, an arrangement of functional elements can thus take place even in the extended state of the bed frame over the entire longitudinal extent of the bed frame. In the known from the prior art solutions, this has not been possible.

It is provided according to a further feature of the invention that the Zargenaufsatz end has connecting extensions. These serve a positionally secure arrangement of a Zargenaufsatzes on the respective spar. In the final assembled state, the connection extensions engage in associated bores of the bed head, on the one hand, and the associated outer frame, on the other hand. A twisting and / or movement of the Zargenaufsatzes relative to the spar is so securely prevented. This ensures the secure arrangement of an adapter element on a Zargenaufsatz and / or the secure receiving a (partial) lying surface element by the Zargenaufsatz.

According to a further feature of the invention, it is provided that the outer frame and the frame attachment each provide a visible surface outside the bed frame.

"Visible surface" in the sense of the invention means the optically visible outer surface of the outer frame and the Zargenaufsatz in the case of use. On such a visible outer surface providing apertures can be completely dispensed with in an advantageous manner, in contrast to the prior art.

In the constructions known from the prior art, square bed profiles are typically used as bedstead rails. Since these are visually less attractive, find aperture use, the outside of the frame are placed on the bed frame spars. Such a construction shows, for example, the aforementioned EP 2 364 685 A1 ,

The bed according to the invention does without such panels, since the outer frames and Zargenaufsätze bed frame outside already provide a visible surface. It is preferred to design the outer frame and, accordingly, also the frame attachment in the respective proportion corresponding to the side rail spars of a possibly existing side rails, so that a total harmonious overall impression is created.

The design of the outer frames and the Zargenaufsätze with a respective outer frame-side viewing surface is the one for the sake of advantage because reduce manufacturing costs and simplifies installation. This is because it is possible to dispense with diaphragms, which is particularly advantageous on the assembly side. In addition, the embodiment of the invention provides a simplification in the handling, since the existing in the prior art constructions between bed frame rail and aperture dirt edge is eliminated, which allows a simplified way to clean.

The outer frame and the Zargenaufsatz of the bed according to the invention are further characterized by an upper in each bed frame height direction end edge, each having a longitudinally extending, nose-like taper. This embodiment makes it possible to arrange functional elements on an outer frame or on a frame attachment in a simplified manner.

For arranging a functional element on an outer frame and / or on a frame attachment, the previously mentioned adapter element is used, which engages behind the longitudinally extending, nose-like taper of the outer frame or frame attachment in a form-fitting manner. The geometric design of outer frame and Zargenaufsatz therefore allows to easily arrange functional elements on the bed frame, because this can be done by simply attaching to the outer frame or the Zargenaufsatz. In this case, the longitudinal, nose-like taper provides a kind of guide rail, so that it is advantageously allowed to move a attached to an outer frame or a Zargenaufsatz functional element in the longitudinal direction, so that a positional fixation of the functional element relative to the outer frame or the Zargenaufsatz is allowed to meet the individual user needs.

The outer frames according to the invention have according to a further feature of the invention via screw channels, which are each accessible bed frame inside.

The screw channels of the outer frames serve to receive screws for the arrangement of particular support receptacles on the outer frames. The support receptacles serve in particular the support of an inner frame, a lying surface element and / or the like. From a constructive point of view, this is in this Connection crucial that the outer frames formed as hollow profiles provide connection points by means of the inside of the frame accessible screw channels, so that to be provided for supporting an inner frame, a lying surface element and / or the like support receptacles can be bolted to the outer frames. An at least partial welding, as is known from the prior art, can thus be omitted, which is particularly for assembly reasons or in case of repair for reasons of simplified disassembly of advantage.

The outer frame and the Zargenaufsatz have according to a further feature of the invention each have a bottom frame height direction lower edge, which has a longitudinally extending, preferably T-shaped groove which is formed opposite to the respective nose-like taper.

This groove is used in particular for receiving clamping screws. Such clamping screws are arranged on the foot side of an adapter element for arranging a functional element on the bed frame. They serve to lock an adapter element and thus a worn by this adapter element functional element on the bed frame, whereby a position assurance is achieved.

An adapter element preferably has a cross-sectionally C-shaped clamp section, the inner contour of which is formed corresponding to the bed frame outer contour of the outer frame and the Zargenaufsatz. Thus, an adapter element in the mounted state surrounds an outer frame or a frame attachment at least partially positively.

An adapter element preferably has a hook section on the top side. In the mounted state, this hook portion engages behind the nose-like taper of the outer frame or frame attachment. A foot portion of the adapter element is supported on the lower edge in the height direction of the outer frame or frame attachment. In this position, the adapter element can be moved both in the longitudinal direction as well as removed by a simple pivoting movement of an outer frame or a Zargenaufsatz again.

The adapter element carries at the foot side a clamping screw, which with the outer frame and Zargenaufsatz provided groove cooperates. As soon as the clamping screw is tightened by a few turns, it engages in the groove of the longitudinal frame on the opening side. In this position, the adapter element and the functional element disposed thereon is still arranged in the longitudinal direction relative to the bed frame rail. However, a removal of the adapter element from the bedstead spar by a twisting movement is no longer possible since the clamping screw engaging in the groove blocks such a twisting movement.

As soon as the clamping screw is tightened a few more turns, it comes with its screw-removed end with the groove bottom in contact, as a result, a clamping takes place. In this position, the adapter element is positionally secured relative to the outer frame or the frame attachment, so that a displaceable movement of the adapter element is relatively blocked with respect to the Bettgestellholm.

The bed according to the invention is equipped according to a further feature of the invention with a side rail. In this case, a side rail has a height-adjustable trained side rail spar, which has a bar, the end receives a cap longitudinally displaceable.

For height-adjustable arrangement of a side rail spar either corresponding guide rails may be provided in the Betthäuptern the bed, or there are side rail posts are used, which are arranged with the interposition of a respective adapter element on Bettgestellholm and turn provide appropriate guide rails for height-adjustable recording a side rail spar. With regard to the extendable design of the bed frame, however, it is of importance that the side rail spar of a side rail is made extendable, which is achieved in accordance with the invention by the fact that the bar of the side rail spar is equipped with caps displaceably mounted thereon. In this case, the Seitengitterholm is surprisingly simple design in its construction, but offers in contrast to the prior art, an extended functionality, and this with a simplified handling. The side rail spar has according to the invention a lath. This lath can be made of wood, a wood material, plastic or other material. It is crucial that they end thanks to the construction according to the invention on any pocket bore and / or must have other receiving device for receiving extension sections, as is known in the prior art. The production therefore proves to be simple and less expensive, because it only requires a cut to length of, for example, rod or rod material to the desired length.

The tailor-made tailor-made to measure is fitted on one end and one on each end with a cap. In this case, a cap is formed as a sleeve member closed on one side, in which the bar is inserted at one end. In this case, the lath takes the cap longitudinally displaceable, that is, the end of the bar provided caps are arranged longitudinally displaceable on this.

The above construction proves to be advantageous in many ways. Thus, the longitudinal beams according to the invention can be used equally both in combination with a non-extended bed frame as well as in combination with a solid bed frame. This possible use achieved with the embodiment according to the invention results from the fact that the longitudinally displaceable arrangement of the caps on the bar ensures a length compensation. The inventive design makes advantageously no visual difference between a retracted and an extended position of the side rail spar. In optical perception, unlike prior art tube-in-tube systems, no transitions between the inner and outer tubes are significant. The provided according to the invention side rail spar has a bar and arranged thereon caps, the relative position of the caps to the bar does not visually significant. The appearance remains unchanged even after a transfer from the retracted to the extended position or vice versa.

The invention makes it possible in total to increase the bed provided by the bed area by pulling out of the bed frame. In this case, the side rails spine a side rail with, that is extend when you pull the bed frame to the same extent. It does not require extended handling, and it is certainly not necessary to replace the side rail spars in the case of a solid bed frame.

According to a further feature of the invention, it is provided that the lath on each of its two large surfaces in each case one center groove extending in the longitudinal direction of the slats having. The design of such a center groove is advantageous in that as a result of this a simplified handling by the user is achieved. Thus, the fingertips of a user's hand can dive into the center groove of the side rail spar at a height adjustment of the side rail, which on the one hand allows a secure gripping, on the other hand allows a simplified force penetration, which in particular simplifies a movement movement of the side rail in the vertical direction upwards.

The caps carried by the crossbar are equipped according to a further feature of the invention, each on the pale side with a concavity, which engages in the final assembled state in the respectively associated center groove of the crossbar. By this embodiment, an additional guidance of the caps is achieved relative to the bar. In particular, a tilting of the caps relative to the bar can be prevented, which allows a permanent secure guidance in the longitudinal direction of the bar. It is according to a further feature of the invention provided that a cap by a stroke of 70 mm to 130 mm, preferably from 80 mm to 120 mm, more preferably from 90 mm to 110 mm, even more preferably 100 mm longitudinally displaceable on the lath is arranged. Thereafter, each cap can be moved by a specific single stroke relative to the bar, preferably by a stroke of 100 mm. In the entirety of both caps so a total stroke can be achieved, resulting in the sum of the two individual strokes. In the case of a single stroke of 100 mm, this results in a total stroke of 200 mm. In this way it is permitted to follow also comparatively large bed extensions.

A cap is preferably arranged captive on the bar. This is to ensure that before a movement, the bar does not accidentally slip out of a receiving cap. It is for this purpose per cap a locking device is provided which ensures the captive arrangement of the cap on the bar.

According to a particular proposal of the invention it is provided that the locking device comprises a spring-loaded locking pin, which engages in the final assembled state in a double-sided closed longitudinal groove.

For the purpose of assembly or disassembly of the locking pin is formed spring loaded. For example, it is fixed in a hole provided by the lath. For the purpose of assembly, it is against the spring force in the of the crossbar provided hole pressed. The associated cap can then be placed on the bar. This is provided on the inside with a corresponding to the locking pin formed longitudinal groove. As soon as this longitudinal groove comes into conformity with the locking pin, it can extend due to the spring force acting on it and snaps into the longitudinal groove. The longitudinal groove is closed on both sides, thus providing so far stops for the locking pin ready. Once the locking pin auffährt in the course of a normal movement on one of the longitudinal groove limiting attacks, a further movement of the cap relative to the bar is denied in this direction. Unintentional removal of the cap from the bar is thus reliably prevented.

The caps are arranged according to a further feature of the invention in each case slat-rotatable on a mechanism for height adjustment of the side rail spar. Such a mechanism may have a sword formed extension for arranging a side rail spar. The cap and the associated sword are equipped with corresponding holes formed to each other, in the final assembled state, a pin is inserted. In this way, a rotatable arrangement of the side rail spar is achieved on the height adjustment mechanism, whereby a diagonal position of the side rail spar is made possible in the case of a movement movement in the vertical direction.

The invention further proposes a device for height-adjustable arrangement of a side rail on a bed, with a height adjustable adjustable in a bed-side guide rail sliding member on which a side rail side rail of the side rail is pivotally mounted, wherein the pivot point for a pivoting movement of the side rail spar outside of the guide rail provided guideway is located.

The from the EP 1 358 824 A1 Known device is characterized, inter alia, by the fact that the connecting the Seitengitterholm with the sliding element connecting element is pivotally mounted on the sliding element. Since the sliding element is in turn received by the guide rail, it follows that the fulcrum around which the connecting element is designed to be pivotable relative to the sliding element lies within the guideway provided by the guide rail. This results in a relatively complex On-site bed assembly or disassembly in case of repair.

Namely, in order to mount a side rail or the side rail spars of a side rail as intended, it is necessary to remove the sliding elements together with pivotally arranged thereon connecting elements from the respectively associated guide rails. For this purpose, appropriate locking and security elements must be removed within the guide rail, otherwise a removal of the sliding element is not possible. After removal of the sliding element, the side rail spars can be pushed onto the end of the respective connecting elements. Then the sliding elements at the one end and at the other end of the side rail spar at the same time are to be re-threaded into the respective associated guide rail and the previously dismantled barrier and safety elements are to be reinserted.

With the solution according to the invention, a construction is proposed which can avoid the above-described assembly or disassembly effort.

Thus, it is provided with the invention that the pivot point for a pivoting movement of the side rail spar lies outside of a guide rail provided by the guide rail. In consequence of this construction, it is advantageously possible to pre-assemble the sliding element along with the connecting element arranged thereon on the manufacturer's side, ie. to insert into the respective associated guide rail. The connecting element protrudes from the side rail spar side out of the guide rail provided by the bed and serves the drehverschwenkbaren arrangement of a side rail spar. In this case, this drehverschwenkbare arrangement of the side rail spar can be realized on the connecting element in a simple manner by a bore-pin arrangement. Advantageously, both a simple assembly and a simple disassembly is allowed, since in contrast to the prior art access to the sliding element is not required. The guide track is preferably formed by a guide groove provided by the guide rail.

The sliding element and the connecting element are preferably fixed to one another, preferably formed in one piece. In contrast to the above solution after the EP 1 358 824 A1 is with the inventive solution just no rotatable arrangement of sliding element and connecting element intended.

With the invention is instead provided that the side rail spar is pivotally mounted on the connecting element. For this purpose, preferably a cap provided at one end of the side rail spar is used. It is preferred that the connecting element on the one hand and the cap of the longitudinal spar on the other hand have mutually correspondingly formed holes through which a pin is guided in the final assembled state. In this way, a pivotable arrangement of the side rail spar is achieved relative to the sliding member, wherein the pivot point or the axis of rotation about which the Seitengitterholm can be pivoted, is formed by the connecting pin.

The side rail spar has a crossbar. This dives einendseitig in a provided by the cap cavity, namely longitudinally displaceable. As a result, a longitudinally displaceable arrangement of the bar is achieved relative to the cap and thus also relative to the connecting element or the sliding element, which ensures the necessary length compensation in the case of a proper height adjustment.

The cap provided according to the invention thus has two functions. On the one hand it provides a rotatable arrangement of the side rail spar on the connecting element, on the other hand it serves the longitudinally displaceable recording of the crossbar of the side rail spar, which allows the length compensation for the purpose of diagonal position.

In contrast to the solution after the EP 1 358 824 A1 Thus, it is not possible for the cap, together with the bar arranged thereon, to be moved relative to the connecting element. According to the invention, it is provided that the bar of the side rail spar is in each case longitudinally displaceable by a cap, thus a longitudinal displacement of the bar relative to the respective cap takes place in the intended use case the cap is formed longitudinally fixed to the respective connecting element.

Fig. 1 can be seen in a schematic representation of a bed 1. This has a bed frame 2, which has a head 32 and a foot main 33. Between the two Bed heads 32, 33 extend spars 4, which are screwed on one end to the head 32 and the other end to the foot 33. The bed heads 32 and 33 form together with the bars 4, the bed frame 2.

Between the two Bedthäuptern 32 and 33, the open longitudinal sides of the bed 1 extend, wherein a side rail 20 is provided for each open longitudinal side.

Each side rail 20 has two in the height direction 19 spaced apart side rail spars 21. These are height adjustable and can be transferred from a non-use position to a use position and vice versa. In the non-use position, the side rail spars 21 are moved to a lower position, allowing unhindered entry into bed. In the use position, the side rails spars 21, however, moved to an upper position, which is for a person lying in bed a fall protection is created.

Fig. 2 lets the bed frame 2 of the bed according to the invention in a detail view closer. As can be seen from this illustration, a flange 35 provided at one end of a spar 4 is used to arrange a spar 4 on a bed head 32 or 33, respectively. This is screwed by means of appropriate screws 36 with the associated bed head 32 and 33 respectively. The bed frame 2 serves to receive a lying surface element, such as a slatted 38 equipped slatted frame like this Fig. 16 lets recognize.

As the representations in particular after the FIGS. 1 and 2 Incidentally, the bed heads 32 and 33 can have guide rails 34 which serve to accommodate the height of the side rail spars 21 of a side rail 20. In this case, a mechanism 31 is used for the height-adjustable arrangement of the side rail spars 21, as will be explained below with reference to FIG Figures 12 and 13 will be explained.

The schematic representation after Fig. 11 lets the above-mentioned components of the bed frame in a cross-sectional view recognize.

The outer frame 5 provides the vorerläuterten cavity 7 which serves the longitudinally displaceable receiving an inner frame 6. Into the cavity 7 project from the outer frame 5 provided screw 49 into it. These serve to receive screws for the purpose of bed frame inside fixing of Liegeflächenelementaufnahmen. On the outside of the bed frame, the outer frame 5 and the frame attachment 8 provide a similarly formed visible surface 14. This is preferably spherical and their proportions adapted to the side rails spars 21 of the side rail 20. Frame inside the frame attachment 8 has a support portion 13, which merges into a stiffening tube 58 end.

In the height direction 19 49 free spaces 50 are provided between the screw channels. In these free spaces 50 engage extensions 59 of the inner frame 6 in the final assembled state. Meanwhile, the screw channels 59 immerse in the final assembled state in free spaces 51 provided by the inner frame 6. In this way, a total of a kind of rail system is formed, which allows a tilt-free guiding an inner frame 6 relative to an outer frame 5.

At the upper end edge 15 in the vertical direction 19, an outer frame 5 or a frame attachment 8 carries the previously described nose-like taper 17. In the arrangement of an adapter element 40 on the outer frame 5 or on the frame attachment 8, the hook extension 46 provided by the adapter element 40 engages behind this taper 17, whereby an undercut is formed, which allows a secure arrangement of the adapter element 40.

The adapter element 40 has a foot portion 45 opposite the hook extension 46, which provides the previously described clamping screw 47. In the secured position, the clamping screw 47 engages in the Nutz 18 of the outer frame 5 and the Zargenaufsatzes 8, which is formed at the lower end edge 16 in the height direction 19 of the outer frame 5 and Zargenaufsatz 8.

The adapter element 40 serves to arrange functional elements 41 on the outer frame 5 or on the frame attachment 8. For this purpose, the adapter element 40 provides bores 48, which are provided with an internal thread and serve to receive fastening screws.

The above-described embodiment of outer frame 5 and frame attachment 8 allows an adapter element 40 to be able to move in the longitudinal direction 3 over the entire longitudinal extent of the bed frame in the extended state, that is also in the areas of the inner frames 6 equipped with a frame attachment 8.

As can be seen from the further figures, a side rail spar 21 has a lath 24 which carries a first cap 22 at the end and a second cap 23 at the other end. The caps 22 and 23 are each arranged longitudinally displaceable on the crossbar 24. Thus, each cap 22 or 23 can accomplish a longitudinal displacement relative to the bar 24, preferably a Einzeihub of 100 mm. As a result, a total stroke of 200 mm is provided. To this total stroke of the side rail spar 21 can be extended or shortened.

How in particular the detailed representation after the Figures 12 and 13 can be seen, the large surfaces 25 of the crossbar 24 are equipped with a central groove 26. This center groove 26 serves two purposes. On the one hand, it allows a user-side simplified handling, since it can engage with its fingertips in the center groove 26. On the other hand serve the center grooves 26 of a rail-like guidance of the end of the bar 24 recorded caps 22 and 23, which have over the center grooves 26 correspondingly formed concavities 27 which engage positively in the assembled state in the center grooves 26, in particular the view Fig. 13 lets recognize.

For a captive arrangement of the caps 22 and 23 on the crossbar 24 has this end each have a locking device 28, which has a locking pin 29 on the one hand and a longitudinal groove 30 on the other hand in the illustrated embodiment. In this case, the locking pin 29 is spring loaded arranged in one of the lath 4 end provided hole. The longitudinal groove 30 is formed as a closed longitudinal groove and formed within the associated cap 22 and 23, in particular as shown Fig. 15 lets recognize. In the final assembled state, the locking pin 29 engages in the associated longitudinal groove 30 of the cap, whereby the distance of the possible longitudinal displacement of the cap 22 and 23 is determined relative to the crossbar 24 by the longitudinal extent of the longitudinal groove 30.

To connect the side rail spar 21 to a mechanism 31 for height adjustment of the side rail spar 21, a blade 54 provided by the mechanism 31 is used. This has holmseitig via a bore 55, which comes in the final assembled state in registration with a provided by the respective cap 22 and 23 bore 52. Through the holes 52 and 55 engages in the final assembled state, a pin 57, as is made Fig. 13 can be seen. In this way, a rotatable arrangement of the side rail spar 21 is achieved on the adjusting mechanism 31.

Like that Figures 12 and 13 Furthermore, the adjusting mechanism 31 has sliders 53, which in the final assembled state engage in guide rails 34 which are provided, for example, by the bed heads 32 and 33, as shown in FIGS Fig. 2 results. Here are each Seitengitterholm 21 a slider 53 is provided which can be connected to each other via a common linkage 56, as the Figures 12 and 13 demonstrate.

The Figures 17 . 18 and 19 show an alternative embodiment of the side rail spar, which is preferred. In this case, the alternative embodiment is characterized in particular by the construction of the locking device 28.

As already described above, the lath 24 of a side rail spar 21 in the final assembled state is each end equipped with a cap 22. The cap 22 receives the bar 24 longitudinally displaceable, so that the bar 24 can be moved over a certain length range relative to the cap 22. FIG. 17 shows in this context the retracted state, whereas FIG. 18 shows the extended state.

In order to effectively prevent the lath 24 from being extended too far out of a cap 22, the side rail spar 21 has an arresting device 28. This arresting device 28 has the following in the exemplary embodiment shown FIGS. 17 to 19 via a latching element 60, which cooperates with a travel limiter 63.

The locking element 60 is designed as a plastic part and mounted in the final mounted state of the end of the bar 24. For this purpose, the locking element 60 has holes 61 through which extend in the final assembled state in the figures not shown fastening means, such as screws, rivets and / or like.

The locking element 60 with respect to the plane of the drawing after FIGS. 17 to 19 on the underside a latch extension 62 ready, which is guided in the final assembled state in a provided by the cap 22 longitudinal groove 30.

The travel limiter 63 is likewise preferably designed as a plastic part. It has a base body 66, which has a spring section 64 in the middle region. This spring portion 64 engages in the final assembled state in a provided by the cap 22 recess 65, as can be seen in particular from the sectional view of the Figures 17 and 18 results. As a result of this engagement of the spring portion 64 in the recess 65 of the travel limiter 63 is locked in its relative position relative to the cap 22 and secured against a sliding movement of the cap 22 out. FIG. 18 indicates the extended state of the side rail spar 21. In this position, the bar 24 is moved to the stop from the cap 22 out. In this case, this position results from the fact that in the course of a movement of the bar 24 in the longitudinal direction of the latch extension 62 of the locking element 60 auffahr the traversing limiter 63. Since this relative to the cap 22 is secured in position in the manner described above, a herausverfahren the lath 24 from the cap 22 is effectively prevented.

The assembly of the locking device 28 can proceed as follows. In a first step, the locking element 60 is first to be mounted on the front side of the crossbar 24. Then, the crossbar 24 is to be inserted into the end of the cap 22 with the end-mounted locking element 60 in the front, in such a way that the latch extension 62 of the locking element 60 comes to lie within the groove 30 provided by the cap 22. Then the Verfahrbegrenzer 63 is in with respect to the plane of the drawing after the Figures 17 and 18 below the slat 24 between the slat 24 and cap 22 resulting gap. Once the Verfahrbegrenzer 63 has reached its intended end position, the spring portion 64 springs out and snaps into the cooperating recess 65 of the cap 22 a. In order to prevent the travel limiter 63 from being pushed in too far, the base body 66 of the travel limiter 63 can have a head area at its end close to the lath, which has a circumferential edge that cooperates with a counter stop of the cap 22. It is thus permitted, the Verfahrbegrenzer 63 until it stops in his Spend end position, in which then the spring portion 64 springs in the manner already described in the recess 65 of the cap 22.
