Description

The invention relates to a side rail for a bed, in particular a hospital and / or nursing bed, with a height-adjustable longitudinal spar, which has a bar, the end receives a cap longitudinally displaceable.

Bed side rails and side railed beds are well known in the art. They are used in particular in the health and / or care sector. A generic side rails is for example from the DE 33 09 174 C1 known.

Side rails can typically be transferred from a non-use position to a use position and vice versa. It is allowed at a located in non-use position side rails a step into the bed. In the position of use, the side rails of a person lying in bed serves as fall protection.

Different side rail designs of the prior art have become known. According to a typical construction principle, a side rail preferably has two longitudinal spars, which are arranged one above the other in the vertical direction. The longitudinal beams are designed to be adjustable in height and can thus be moved from a non-use position to a use position and vice versa. From the prior art, it has become known in this context that the bed has bed heads, each providing guide rails, in which the longitudinal beams are each mounted height-adjustable end. Such a construction is for example from the DE 20 2011 052 412 U1 known. Comparable constructions are from the DE 202 18 030 U1 and the EP 1 817 985 B1 known according to the construction according to the DE 202 18 030 U1 an additional pivoting movement of the longitudinal beams is allowed and the teaching of the EP 1 817 985 B1 to support the longitudinal beams additional support post provides, which allows to divide a side rail in the longitudinal direction into two independent sections.

The height adjustment of a generic side rail is done on the user side in such a way that initially a height adjustment with respect to the one bed head and then a height adjustment with respect to the other bed head is made. It results as a result of this handling a moment of skew, namely, when the side rails or the longitudinal beams of the side rail with respect to the one bed head are already height method, with respect to the other bed head but not yet. In this intermediate position, the longitudinal struts of the side rail between the bed heads are diagonal to the bed surface provided by the bed. To allow this diagonal position, it requires a length compensation. A height adjustment of the type described above is therefore only possible if the longitudinal bars of the side rail allow a length compensation tolerance.

From the prior art, it has become known in this context to use so-called swords, which are each arranged at the end of a longitudinal spar. The swords are arranged longitudinally displaceable within a respective end of the longitudinal spar formed pocket. The swords in turn serve the rotatable arrangement of the spar to a height adjustment mechanism, which allows in combination with the slidable in the longitudinal direction of the spar arrangement of the swords in the associated pockets a diagonal position of the side rail spars.

From the prior art side rail spars are also known, which can be used in combination with a length-extendable bed. Such side rail spars are telescopically formed on the tube-in-tube principle and allow depending on the design of the bed extension a stroke of up to 200mm. Such a tube-in-tube principle discloses, for example, the EP 2 186 499 A1 ,

Although the above-described constructions have proven themselves in everyday practical use, they are not free from disadvantages. So it requires differently trained side rails for extendable beds on the one hand and standard beds, that is Beds that are not extendible in length, on the other hand. Moreover, it is disadvantageous in the previously known tube-in-tube systems that, when extended, an unavoidable formation of a step-shaped transitional region between the inner tube and the associated outer tube occurs. This design is not only visually unsightly, it also provides depending on the build quality a sharp-edged transition between inner and outer tube, which is a risk of injury. Furthermore, on the geometry of the outer tube matched clamp elements for the arrangement of functional elements on the side rails, such as remote controls and the like not on the extended part of the side rail, that is attached to the exposed in the extended state inner tubes of the side rail. The handling is affected.

Another disadvantage is the comparatively complicated construction of a side rail spar, since in the case of an adaptation to a bed extension on the one hand telescoping is provided, but on the other hand also a slidably receiving the ends arranged on a side rail spar swords diagonal compensation is allowed. This comparatively complicated design makes the production of corresponding side rail spars or side rails consuming and therefore expensive.

It is based on the Vorerläuterten the object of the invention to propose a side rail of the type mentioned, which allows for improved handling with a simple design at the same time.

To solve this problem, a side rail for a bed with the features of claim 1 is proposed by the invention.

The longitudinal spar of the side grille according to the invention is surprisingly simple in design, but offers in contrast to the prior art, an extended functionality, and this with a simplified handling.

The longitudinal spar for the side rails according to the invention has a lath. This lath can be made of wood, a wood material, plastic or other material. The decisive factor is that, thanks to the design according to the invention, it does not have to have any pockets at its end for receiving swords. The Manufacturing 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 each end. In this case, the lath takes the caps on longitudinally displaceable, that is, the end of the bar provided caps are arranged on this longitudinally displaceable.

The above construction proves to be advantageous in many ways. Thus, the longitudinal beams according to the invention can be equally used both for standard beds, that is, for non-extendible beds in length, as well as for such beds, which are equipped extendable in length. The still to be made according to the prior art distinction thus deleted. This simplifies logistics, posture and assembly.

The possibility of using the side lattice according to the invention with standard beds on the one hand and extendable in length beds on the other results from the fact that the longitudinally displaceable arrangement of the caps on the crossbar of a longitudinal beam both a length compensation in a diagonal position of a longitudinal spar and a length compensation in the case of an extendable bed can guarantee. In this respect, in contrast to the prior art, it is no longer necessary to distinguish between side rails for standard beds on the one hand and side rails for length-extendable beds on the other hand.

Unlike prior art pipe-in-pipe systems formed in a longitudinal extension of a provided for the side rails according to the invention longitudinal spar no sharp under certain paragraph transitions, making the side rails according to the invention higher safety standards.

In addition, the side rail according to the invention makes optically no difference between a retracted and an extended state. In optical perception, unlike a tube-in-tube system, no transitions between the inner and outer tubes come into play. The provided according to the side rails according to the invention longitudinal spar has a bar and arranged thereon Caps, wherein the relative position of the caps to the lath optically does not matter. The appearance remains even after a transfer from the retracted to the extended position or vice versa rather unchanged.

The caps are each arranged slat remotely rotatable on a mechanism for height adjustment of the longitudinal spar. Such a mechanism may have a blade formed as a blade for arranging a longitudinal spar. In contrast to the prior art but it requires the purpose of a diagonal compensation no relative displacement between the cap on the one hand and Höhenverstellmechanismus other. Such a length compensation is accomplished in the manner already described by the longitudinally displaceable arranged on the bar caps. In this respect, it only requires a rotatable arrangement of the respective cap on the associated height adjustment mechanism, which results in a total of simplified construction, both in the production as well as in the assembly or disassembly.

From the prior art is in this context from the EP 1 358 824 A1 a device for the height-adjustable arrangement of a side rail on a bed has become known. This known device has a sliding element, which is mounted vertically movable in a bed-side guide rail. This slider serves the one-sided support of a side rail spar of a side rail, wherein the arrangement of the side rail spar on the slider a connecting element in the form of a sword is arranged under the interposition of the side rail spar on the slider. This prior art 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 complicated bed assembly on site or disassembly results 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 in the prior art, the sliding elements together with pivotally arranged thereon connecting elements of the to remove each 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. When then the sliding elements at one end and at the other end of the side rail spar at the same time in the respective associated guide rail to thread again and the previously disassembled locking and security elements are to be reinstated.

With the solution according to the invention, a construction will suggest that can avoid the above-described assembly or disassembly effort. Thus, it is provided according to the invention that the mechanism for height adjustment has a height-movable guided in a bed-side guide rail slider on which the longitudinal spar, that is the Seitengitterholm is pivotally mounted, wherein the pivot point for a pivoting movement of the longitudinal spar outside of the guide rail provided by the guideway lies.

With the invention is provided according to the above-described construction, in contrast to the prior art, that the pivot point for a pivoting movement of the longitudinal beam is outside of the guide rail provided by the guideway. As a consequence of this construction, it is advantageously possible to pre-assemble the slider, that is to say the sliding element together with the blade arranged thereon, by the manufacturer, that is to say insert it into the respective associated guide rail. The sword protrudes longitudinal spar side out of the provided from the bed guide rail and serves the drehverschwenkbaren arrangement of a longitudinal spar. In this case, this drehverschwenkbare arrangement of the longitudinal spar on the sword can be realized in a simple manner by a bore-pin arrangement. Advantageously, both a simple installation and a simple disassembly is permitted, since, in contrast to the prior art, access to the slider is no longer required.

According to a further feature of the invention, it is provided that the lath has on its two large surfaces in each case one center groove extending in the longitudinal direction of the slats. The design of such a center groove is advantageous in that as a result a simplified handle is achieved by the user. Thus, the fingertips of a user's hand can be adjusted in height adjustment of the side rail in dipping the center groove of the longitudinal spar, which on the one hand allows a secure gripping, on the other hand allows a simplified introduction of force, 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 permanently 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 certain single stroke relative to the crossbar, 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 during 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 pressed against the spring force in the hole provided by the lath. The associated cap can then be placed on the crossbar be put on. This is provided on the inside with a corresponding to the locking pin formed longitudinal groove. Once this longitudinal groove comes into line with the locking pin, this 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 in the course of a proper Vefahrbewegung auffährt 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.

According to a further feature of the invention, a cap is formed of plastic.

The slider and the sword are preferably formed fixed to each other, preferably in one piece. In contrast to the previously explained teaching according to the EP 1 358 824 A1 Thus, with the device according to the invention, no rotatable arrangement of slider on the one hand and sword on the other hand is provided.

The embodiment of the invention instead provides that the longitudinal spar is pivotally mounted on the sword. For this purpose, according to the invention, the previously described, end of the longitudinal spar provided cap is used.

According to the invention, it is provided according to a further feature of the invention that the slider of each longitudinal spar is in each case equipped with a holding element. This holding element is configured in the manner of a bracket and cooperates with an abutment, which is supported by the respectively associated support spar, that is, by the support spar, which provides the guide rail for the slider. In the use position, the bow-shaped holding element engages behind the abutment, so that the associated longitudinal spar is suspended from the abutment on the support spar side.

The holding member is pivotally mounted on the slider, so that a transfer of the side grid is realized in the non-use position in a simple manner that the holding element is pivoted so that it comes out of engagement with the associated abutment. As a result, the retaining element is released, so that the longitudinal spar along the associated guide rail, also called guide groove, run free and can be transferred from the use position to the non-use position. The The above-described holding element abutment construction impresses with its simplicity both in the structural design as well as in the handling. In order to transfer the longitudinal spar of the side rail from the non-use position into the use position, this is to be taken by the user and moved counter to the force acting on the longitudinal beam weight up along the guide rails provided by the support rails. Once the longitudinal beam has arrived in its position of use, engage behind by the sliders of the longitudinal spar respectively provided holding elements, respectively associated abutment, as a result of which a support of the longitudinal spar against the spring force acting on it with the consequence that the longitudinal spar in this position of the the abutment supporting support struts is kept suspended. For the purpose of the return to the non-use position, the holding elements for the separation of the associated abutments are to be pivoted, which then allows a traversing movement of the longitudinal spar of the weight down to the non-use position.

The retaining element is preferably spring-loaded, in particular resilient. It is therefore under spring preload. In this case, the spring bias ensures that the holding element is held in the closed position, that is, the position that occupies the holding element in cooperation with the associated abutment. In a traversing movement of the longitudinal spar from the non-use position into the position of use, the spring bias thus ensures that the holding element snaps into the associated abutment upon reaching the position of use. A manual operation is not required so far. For the transfer of the longitudinal spar from the position of use in the non-use position, the holding elements of the longitudinal spar are first to be pivoted into their respective release position, against the respectively acting spring preload. This has to be done by manual actuation of the retaining elements. In this respect, an unintentional release of the holding elements and thus of the associated longitudinal spar is not possible, which is particularly advantageous in terms of safety aspects.

The holding element is spring-loaded, which can be done, for example, that a corresponding spring is provided, which holds the holding element in the closed position under spring tension. It is, however, particularly preferred to design the retaining element so that it is spring-loaded in that it itself is resilient. On additional spring elements can be omitted according to this alternative embodiment, which in particular for reasons of simplified cost-effective production and Maintenance is beneficial.

The holding element has according to a further feature of the invention via two articulated arms which engage in the final assembled state in corresponding holes of the slider. The bow-shaped retaining element has two bow arms, which are coupled together via a connecting bow. End of the hanger arms, the articulated arms are formed with which the connection to the slider is formed by the articulated arms engage with their respective free ends in correspondingly designed holes in the slider. This construction proves to be advantageously comparatively simple and safe to handle. In this case, the pivotable arrangement of the retaining element on the slider is effected via the engaging in the holes articulated arms of the holding element.

According to a particularly preferred embodiment of the invention, the articulated arms are spaced from each other in the height direction of the holding element. This embodiment has the effect that the bearing point of the retaining element and the pressure fulcrum, which is set in the intended use case during actuation, differ geometrically from one another. As a result, a resilient return movement of the retaining element in the direction of the closed position is effected. This configuration therefore makes it possible to effect both the connection of the retaining element to the slider and the resilient recovery of the retaining element in its closed position by a simple structural measure. Additional components are not required.

According to a further feature of the invention, a securing element is provided which engages around the two bracket arms of the retaining element. This fuse element fulfills two functions. On the one hand, because of its arrangement encompassing the retaining element, it ensures that the two bow arms of the retaining element can not spread apart unintentionally. This has a positive effect on the reliability in an advantageous manner. On the other hand, the securing element of the user-side operation of the holding element, for which purpose is preferably provided to provide the fuse element with a handle that can be taken on the user side in a simple manner.

According to a further feature of the invention it is provided that the with the Holding element cooperating abutment is designed as a hook. In the position of use of the side rail, the holding element engages with its connecting bracket designed as a hook abutment. In order to move the side rail in the non-use position, it is only necessary to transfer the retaining element from the closure to the release position, as a result of which the two arms of the retaining element interconnecting connecting arc is separated from the formed as a hook abutment.

In order to be able to prevent the bow-like holding element from slipping unintentionally from the abutment designed as a hook, it is proposed according to a further feature of the invention that the hook has a retaining projection on the input side. In this way it is ensured that the connecting bow of the holding element can not slide off the abutment. The retaining projection serves as additional protection, since already the resilient bias of the support member ensures that this is held in the closed position and can not accidentally go into the release position.

The retaining projection has a further advantageous function. In order to enable a pivoting of the retaining element from the closed position to the release position, the retaining projection is overcome. This can be achieved only in that the side rails in use position in the vertical direction slightly, that is raised by a few millimeters, that is moved upwards, and to the extent that the retaining projection releases the retaining element insofar as that a transfer of the same from the closed position in the release position is possible. In this way, a two-hand release is realized, which increases the security with the scope of the side rail according to the invention again. "Two-hand unlocking" in the sense of the invention means that a proper unlocking of the side grille on the user side can be made only two-handed. With a first hand to seize the side rail and from the use position out to move up to the extent that in the manner described above, a transfer of the retaining element in the release position in the first place is possible. In this position, the side rails must be held with one hand of the user. Only as long as the side rails are in this position, the user with another hand can cause a transfer of the retaining element in the release position and thus ultimately unlocking. This "two-handed unlocking" has the advantage that the risk of injury is minimized due to actuation of the side rail.

According to a further feature of the invention it is provided that the abutment is formed as part of an end cap insertable into the guide rail of a support spar. This embodiment proves to be structurally simple, which simplifies the production and any assembly or maintenance. It can be provided according to a further feature of the invention to equip the guide rails with a traversing stop, which makes it possible to exclude user-side operating error. In the position of use of the side rail, the sliders are positioned leaving a gap to the travel stop. The distance to the travel stop corresponds approximately to the vertical extent of the retaining projection, formed as a hook abutment or exceeds this in the height direction by a few millimeters, in order to compensate for any tolerances can. In order to transfer the side rail into the non-use position, this is first in the above-described manner to move upward, so that a pivoting of the retaining element on the associated retaining projection is possible in the first place. The Veran stop on the user side serves to be able to move the side rail from the use position to stop up, which allows the user side in a simple manner to identify the position of the side grille in which a pivoting movement of the retaining element from the closed position to the release position is possible ,

With the invention, a bed is further proposed that is equipped with a side rail of the type described above.

Fig. 1 can be seen in a schematic representation of a bed 1. This has a bed frame 19, which has a foot 21 on the one hand and a head 20 on the other. Between the two Bedthäuptern 20 and 21, the open longitudinal sides of the bed extend, wherein each open longitudinal side a side rail 2 is provided.

Each side rail 2 has two spaced longitudinally spaced from each other in the height direction 24 Longshome 3. These are adjustable in height and can be transferred from a non-use position to a use position and vice versa. In the non-use position, the longitudinal beams 3 are moved to a lower position, the allowed an unhindered entry into bed. In the use position, however, the longitudinal bars 3 are moved to an upper position, which is created for a person lying in bed a fall protection.

The longitudinal struts 3 of the side grille 2 according to the invention each have a bar 4, which carries a first end cap 5 at one end and a second cap 6 at the other end. The caps 5 and 6 are each arranged longitudinally displaceable on the crossbar 4. Thus, each cap 5 or 6 can accomplish a longitudinal displacement relative to the bar 4, preferably by a single stroke of 100 mm. As a result, a total stroke of 200 mm is provided. To this total stroke of the longitudinal spar can be extended or shortened.

How in particular the detailed representations after the FIGS. 2 and 3 can be seen, the large surfaces 7 of the crossbar 4 are equipped with a central groove 8. This center groove 8 serves two purposes. On the one hand, it allows easier handling on the user side, since it can engage with the fingertips in the center groove. On the other hand, the middle grooves 8 serve a rail-like guidance of the end of the bar 4 recorded caps 5 and 6, which have over the center grooves 8 correspondingly formed concavities 9, which engage positively in the assembled state in the center grooves 8, in particular the view Fig. 3 lets recognize.

For a captive arrangement of the caps 5 and 6 on the crossbar 4, this end has in each case via a locking device 10, which has a locking pin 11 on the one hand and a longitudinal groove 12 on the other hand in the illustrated embodiment. In this case, the locking pin 11 is spring-loaded in one of the lath 4 end provided hole arranged. The longitudinal groove 12 is formed as a closed longitudinal groove and formed within the associated cap 5 and 6, in particular as shown Fig. 5 lets recognize. In the final assembled state of the locking pin 11 engages in the associated longitudinal groove 12 of the cap, whereby the distance of the possible longitudinal displacement of the cap 5 and 6 is determined relative to the crossbar by the longitudinal extent of the longitudinal groove 12.

For connecting the longitudinal beam 3 to a mechanism 13 for height adjustment of the longitudinal beam 3, a provided by the mechanism 13 sword 14 is used. This has holmseitig via a bore 15, which in the final assembled state in Cover comes with a provided by the respective cap 5 and 6 bore 16. Through the holes 15 and 16 engages in the final assembled state, a pin 17, as is made Fig. 3 can be seen. In this way, a rotatable arrangement of the longitudinal beam 3 is achieved on the adjusting mechanism 13, wherein the axis of rotation, around which a pivoting movement 25 is possible, is defined by the pin 17.

Like that FIGS. 2 and 3 can also be removed, the adjusting mechanism 13 has a slider 18 which engages in the final assembled state in a guide rail 22 which is provided for example by one of the Bedthäupter 20, 21 of the bed 1, as is apparent in particular from the illustration Fig. 6 results. The slider 18 is movable within this guide rail 22 in the height direction 24.

Per longitudinal beam 3 two sliders 18 and two swords 14 are provided. Wherein one slider 18 together with the sword 14 arranged thereon is provided on one end and the other slider 18 with the sword 14 arranged on the other end side of the respective longitudinal spar 3. Come per side rails 2 more longitudinal bars 3 are used, so accordingly more sliders 14 and 14 swords are provided for the other longitudinal beams.

Fig. 2 makes such a further slider 27 for arranging a further longitudinal spar 3, not shown in the figures recognize. It is provided that the sliders 18 and 27 are coupled together via a common linkage 28. The linkage 28 is formed in the manner of a loop, which allows that with respect to the image plane after Fig. 2 lower slider 27 can be moved relative to the upper slider 18. In this way, it is ensured that the two provided by a side rail 2 longitudinal beams 3 when disassembled into a transfer to the use position or process in a transfer to the non-use position in the height direction 24 to each other.

The above-described adjustment mechanism 13 allows a length compensation of the longitudinal bars 3 in the longitudinal direction 26 and a pivoted orientation of the longitudinal bars 3 relative to the bed frame 19. In this case, the pivot point 23 is for a pivoting movement of a longitudinal beam 3 outside of a guide rail 22 provided guideway. This advantageously allows a simple Access to the sword 14 with the longitudinal beam 3 connecting pin 17, which allows easy installation or in case of repair easy disassembly.

As this is detailed in Fig. 7 is designed, the slider 18 has a holding element 29. This is designed as a bracket and has a first bail arm 36 and a second bail arm 37, which are coupled together via a connecting bow 35. At the ends of the yoke arms 36 and 37, articulated arms 32 and 33 are respectively provided, wherein these articulated arms 32 and 33 are spaced from one another in the vertical direction of the holding element 29, in particular the illustration according to FIG Fig. 7 lets recognize.

To arrange the retaining element 29 on the slider 18 are provided by the slider 18 holes 34 into which the articulated arms 32 and 33 engage in the final assembled state.

On the hanger arms 32 and 33, a securing element 38 is pushed in the final assembled state. A view of the fuse element 38 is Fig. 9 refer to.

As the representation after Fig. 9 can recognize, the securing element 38 has two arms 39 and 49, which extend starting from a base body 41 and form a volume space 48 between them. In this case, the volume space 48 of the receptacle of the retaining element 29, in which receiving position the arms 39 and 49 of the securing element 38 engage around the bow arms 36 and 37 of the retaining element 29.

For a spreading apart of the hanger arms 36 and 37 is prevented, which causes a secure fit of the holding member 29 on the slider 18.

The fuse element 38 also carries an actuator 40, which serves a user-side operation, as will be apparent from the further explanation.

For an end-side closure of the guide rail 22, which is designed in the manner of a groove, serves an end cap 42, as is apparent in particular from the illustration Fig. 8 results. This end cap 42 provides on the one hand a cover plate 46 and on the other hand designed as a hook abutment 30 and a trained in the form of a web travel stop 43 (cf. Fig. 7 ). The formed as a hook abutment 30 has the input side via a retaining projection 47. This is leaving a gap opening 44 spaced from the travel stop 43rd educated. Opposite the retention projection 47, there is further provided a ramp 45 from the abutment 30 formed as a hook.

The holding member 29 is resiliently arranged on the slider 18 due to the above-described embodiment and is held under spring bias in its closed position. For the transfer of the retaining element 29 from the closed position into the release position, this is to be pivoted against the spring bias acting on the retaining element 29 with reference to the plane of the drawing Fig. 7 to the right, that is from left to right.

The operation of the above-described construction is as follows.

In the non-use position, the longitudinal beam 3 is in a lower position relative to the bed 1, so that an entry into the bed 1 is possible. If now the longitudinal beam 3 are moved into its position of use, so this is to be moved in the height direction 24 upwards. In this case, slides him relative to the support member 31 supporting the slider 18 in the associated guide rail 22nd

As soon as the connecting bow 35 of the retaining element 29 reaches the ramp 45 formed on the abutment 30, pivoting of the retaining element 29 into the release position, ie pivoting of the retaining element 29 counter to the spring force acting on the retaining element 29, is effected by further vertical movement of the longitudinal spar 3 with reference to the drawing plane Fig. 7 to the right. Once the holding member 29 has reached the release position, the connecting sheet 35 is guided at a further continued movement movement of the longitudinal spar 3 through the gap opening 44 between abutment 30 on the one hand and traverse stop 43 on the other. As soon as the retaining element 29 has passed the retaining projection 47 with its connecting bow 35, it snaps back into its closed position due to the acting spring bias and thus reaches behind the retaining projection 47. A further movement of the longitudinal spar 3 in the upward direction is not possible in this position reached. because the associated slider 18 rests on the travel stop 43.

The transferred into the position of use longitudinal spar 3 can now be released on the user side, wherein it is mounted quasi hanging and on the holding element 29 supported on the abutment 30. A second longitudinal beam 3 is the movement of the first longitudinal beam 3 due to its coupling via the connecting bracket, that is, the linkage 28 (vgl Fig. 2 ) followed.

If now the side rails are transferred from the position of use in the non-use position, the longitudinal beam 3 is first to take and to move to stop in the vertical direction upwards, namely to halteelementseitig the retaining projection 47 to overcome. For this purpose, the slider 18 of the longitudinal beam 3 in the position of use, leaving a distance from the travel stop 43 is arranged. At this distance, the longitudinal beam 3 can be moved from its position of use upwards in the vertical direction. As a result of this movement, the retaining projection 47 releases the connecting bend 35 of the retaining element 29 so that it can be operated by the actuator 40 on the user side and thus pivoted out of the closed position into the release position against the spring force acting on the retaining element 21. Following the weight force, the side rail with its longitudinal bars 3 can now be moved downwards into the non-use position along the guide rail 22.

Exemplary embodiments of a foot 20 and a head 21 are the head FIGS. 10, 11 and 12 refer to. As can be seen from these figures, supporting spars 31 are used for the height-displaceable or adjustable arrangement of the longitudinal struts 3 of a side rail. These are formed as a respective component of the foot 20 and of the head 21, respectively. For height-adjustable arrangement of the longitudinal members 3, the support bars 31 are formed with guide rails 22, as shown in detail by means of FIGS. 10 to 12 results, which each relate to different embodiments.

The FIGS. 10, 11 and 12 let each detail of the serving as the head 21 headboard of the bed 1 recognize. In this case, such a head 21 is formed of a plate 50 on the one hand and support bars 31 on the other hand, wherein the support bars 31 provide grooves 51, in which the plate 50 of a head of the head 21 is inserted at the edge. To further secure the respective plate 50 locking pins 52 may be provided, as the embodiments of the FIGS. 10 and 12 reveal.
