Description

The invention relates to a bed, in particular a hospital and / or nursing bed, with a side rail having two height-adjustable longitudinal bars, which are convertible from a use position to a non-use position and vice versa, wherein the lower position in the use position of the two longitudinal bars is telescopic.

Beds in general and hospital and / or nursing beds in particular are well known from the prior art, which is why it does not require a separate documentary proof of this stiffness. It is therefore only an example of the EP 2 364 685 B1 referenced, which discloses a generic bed.

A generic bed has a side rail, preferably two side rails, each longitudinal side of the bed is associated with a side rail. The purpose of a side rail is primarily to protect a person lying in bed from accidentally falling out of bed. Side rails serve as far as the safety of a person lying in bed. As a rule, side rails in the hospital and / or nursing area are used for hospital and / or nursing beds.

Side rails can usually be transferred from a use position to a non-use position and vice versa. In the non-use position of the side rail, it is possible to board. The vorerläuterte protective effect results in the use position of the side rail.

The from the EP 2 364 685 B1 Previously known side rail construction has two longitudinal spars, which are held at one end by means of a provided by a bed head leadership höhenverfahrbar and the other end are pivotally mounted on a support post, which support post is formed telescopic. The advantage of this known construction is in particular that a simultaneous transfer of both the support post and the pivotally arranged thereto longitudinal bars from the use position in the non-use position and vice versa is possible.

Although the previously known construction has proven itself in everyday practice, is they are not free from disadvantages. Thus, the prior art side rail construction also builds in non-use position, the side rails comparatively high, which may conflict with the use of appropriately thin mattresses an unhindered entry into bed. A further disadvantage is that the one-sided support of the longitudinal beams provided support post project due to their telescoping design beyond the lower edge of the frame profile of the bed frame, which limits the Höhenverfahrbarkeit the bed frame down.

From the prior art is according to the DE 2 064 017 a bedside part known which has on the bed frame vertically arranged rod-shaped guide elements, each forming a narrow side of the bed side part. The bed side part also has a plurality of extending parallel to the bed longitudinal direction rods which are held and guided by the guide elements. Also, this prior art side rail construction builds in non-use position of the side rail disadvantageously comparatively high.

The DE 297 05 820 U1 relates to a side rest for a hospital and / or nursing bed, which is designed to be pivotable. For this purpose, the side rest has pivot lever pairs, which are received in non-use position of the side back of a cavity of a side protection of the side back.

From the DE 20 2014 103 282 U1 is known a side rail, which has a movable side rail element, which includes at opposite ends in the bed longitudinal direction bearing areas which are mounted relative to holding elements movable. In this case, the side rail is set up such that in a relative movement of a storage area to the associated holding element, a train in a tension element is effected.

The US 3,851,345 shows a side rail device which has pivotally formed vertical beams, which can be moved from an upright position in the use position in a non-use position orientation. The vertical beams take between them longitudinal beams, which are each designed to be telescopic.

Starting from the above-described prior art, it is the object of the invention to propose a novel side rail construction that fails as possible to save space and beyond the bed frame is not limited in its ability to be moved in the height direction down.

To solve this problem, a bed of the generic type is proposed with the invention, which is characterized in that on the telescoping longitudinal spar einendseitig and the other end each have a first and a second articulated arm are each pivotally mounted, wherein the pivot points of the first and second articulated arm to each other are formed spaced apart, wherein the first articulated arms at the other end are each pivotally mounted on the other longitudinal spar and the second articulated arms at the other end are each arranged pivotably on a support beam.

The side rails according to the invention can be accordion-like pivoted from the use position to the non-use position, so that it occupies a non-use position a very compact size. In this case, the side rails in non-use position in the vertical direction so little on that even in the case of using comparatively thin bed mattresses, a projecting beyond the bed mattress provided by the bed surface is omitted by the side rails. This is not a hindrance to bed in a not in use position located side rails even with comparatively thin mattresses.

An advantage of the embodiment of the invention is also that the side rail does not project beyond the lower edge of the frame profile of the bed frame down, which allows the side rails according to the invention in combination with so-called ultra-low beds to use, that is, with beds, the bed frame to rest can be moved down to the ground. With previously known from the prior art side rails this is not possible.

The side rails according to the invention has a in the use position of the side rail upper rail on the one hand and a lower rail on the other. These two spars are coupled by means of first articulated arms, wherein these first articulated arms are arranged in each case one end side and the other end rotatable on the respective longitudinal spar. In combination with the telescoping of the lower longitudinal beam, this arrangement gives a relative displacement of upper to lower longitudinal spar in the height direction.

There are also provided two second articulated arms. These are each one end side as the other end pivotally mounted on the lower longitudinal spar and arranged on a support beam. This causes in combination with the telescoping of the lower longitudinal beam an adjustment of the lower longitudinal spar relative to the spar in the height direction, and thus a displaceability of the upper longitudinal spar relative to the spar in the height direction.

The lower longitudinal spar of the side rail therefore carries at one end as the other end side pivotally mounted thereon arranged first and second articulated arms. In this case, it is provided according to the invention that the respective pivot points of the first and second articulated arm are arranged at a distance from one another. The arranged on the lower longitudinal beam articulated arms therefore do not form a common pivot point. This configuration ensures advantageously that it is not at a displacement of the upper and / or the lower longitudinal spar in the height direction, ie at a transfer of the side grid from the non-use position to the use position and vice versa to tilting the telescoping soliciting Holmabschnitte comes. This "double pivot" design thus ensures that the communicating sections of the telescoping longitudinal spar are always guided coaxially to each other. The spar sections ride into each other when the side rail is moved to its non-use position, whereas they move apart when the side rail is transferred to its position of use.

The above-described construction makes it possible as a result that when transferring the side rail from the use position to the non-use position, the two longitudinal beams move down in the height direction, wherein the articulated arms can swing in due to the telescoping of the lower longitudinal spar. This provides in the non-use position an extremely compact and less bulky arrangement, which is much more space-saving in contrast to conventional side rails.

The upper position of the two longitudinal members in the position of use provides, according to a further feature of the invention, a volume space open towards the lower longitudinal member. In this volume space when transferring the side rail from the use position in the non-use position, the first articulated arms and the second, that is, lower longitudinal beam at least partially submerge. This provides a further improved space-saving arrangement in non-use position. For the purpose of forming the volume space according to the invention, it is provided that the upper longitudinal beam, which is upper in the vertical direction, is preferably U-shaped in cross-section.

According to a further feature of the invention, it is provided that the carrier beam is formed as a separate component, which provides for the pivotable arrangement of the second articulated arms respective bearing points.

The design of the support beam as a separate component is particularly for assembly reasons of advantage. Thus, the side rails Tragholmseitig be easily arranged on the bed, for example by screwing. Depending on the desired configuration, the side rails can be mounted either on a bed frame of the bed or on a lying surface element received by the bed frame, such as a slatted frame, whereby the arrangement of the side grid on a lying surface element brings with it the advantage that it together with the lying surface element is pivotable. The support beam can be formed in a simple manner as a flat material, which has one end side as the other end either bearing pin for the articulated arms or has holes to be inserted into the corresponding hinge pin. Preferably, hinge pins to be used in bores can equally serve for arranging the support beam on the bed frame or on the lying surface element.

As an alternative to the above-described embodiment, it can be provided that the articulated arms are arranged directly on the bed, that is to say on the bed frame or on the lying surface element. In this case, the support beam is formed as an integral part of a provided by the bed bed frame or lying surface element.

It is provided according to a further feature of the invention that the one-sided or the other end of the telescopic longitudinal spar respectively arranged articulated arms are formed positively guided with respect to their relative position to each other. This forced operation causes the one-sided or the other end side respectively arranged on the longitudinal beam articulated arms always include the same angle to the longitudinal beam. It is thus advantageously avoided a non-uniform spacing guide. By inventively provided forced operation are the mutually associated Articulated arms synchronized in their movement, so that they always swing in the actuation case in an identical manner or swing.

The movement synchronization can be achieved according to a further feature of the invention in that the mutually associated articulated arms have an interlocking toothing. For this purpose, each articulated arm has a tooth contour assigned to the other articulated arm, which tooth contours intermesh in the final mounted state of the side rail, whereby the positive guidance is given.

It is provided according to a further feature of the invention that the telescoping longitudinal spar has two sections, which are arranged movable relative to each other with the interposition of an energy store. As such an energy storage, in particular, a coil spring is used.

The energy storage acts on the two articulated arms, in such a way that when transferring the side rail from the non-use position into the use position, a moving apart of the sections of the telescoping tube and thus pivoting of the articulated arms supported in the position to be taken for the use of the side rail position becomes.

The energy store is preferably arranged invisibly within a cavity provided by the telescoping longitudinal spar for a user. The preferably designed as a spring energy storage is stretched at a transfer of the side rail from the use position in the non-use position. A spring tension is thus under the action of the force acting on the side rails in the transfer case weight force. For this purpose, a driver is positioned on the inside of the telescoping longitudinal spar, which entrains and spans the spring serving as a force storage in a transfer of the side rail in the non-use position. If, in the case of transferring the side rail into the use position, the same is raised, the articulated arms pivot in the manner already described. In this case, the serving as a force storage spring relaxes at the last moment of the pivoting movement, whereby the divergence of the telescopic longitudinal spar and thus the pivoting of the articulated arms is spring-assisted to the final position of use. Advantageously, it is so avoided an otherwise necessary two-handed operation.

Upon reaching the final position of use lock the two sections of the telescopic longitudinal spar, so that they are secured in their relative position. An unintentional transfer of the side rail from the position of use in the non-use position is thus prevented. In order to accomplish such a movement movement, it is first necessary to release the locking device. This happens on the user side, for example, by pressing a button.

It is provided according to a further feature of the invention that the first and / or the second articulated arms are force-coupled. This can be realized, for example, by a force coupling the individual articulated arms cable. Advantageously, this embodiment provides a movement synchronization of the two Gelenkarmpaare, whereby an always parallel alignment of the upper and lower spar is ensured. However, this embodiment is purely optional, since it is not necessary for a proper function of the side rails according to the invention to guide the longitudinal beams parallel.

According to a particular proposal of the invention it is provided that a arranged with the one end of the telescopic longitudinal beam articulated arms cooperating, first locking element and arranged with the other end of the telekopierbaren longitudinal spar joint arms cooperating, second locking element are provided, wherein in the use position of the side rail, a rotational movement of the articulated arms means the locking elements is prevented.

Thereafter, the side rail has two locking elements, namely a first locking element and a second locking element. In this case, the first locking element acts with a first Gelenkarmpaar, ie with the one end of the telescopic longitudinal beam arranged articulated arms and the second locking element with a second Gelenkarmpaar, that is the other end of the telescoping longitudinal spar arranged articulated arms together. By means of these locking elements, the articulated arms are blocked in their twisting movement when the side rails are in the position of use. The inventively provided locking elements therefore ensure that prevented in the use position of the side rail a rotational movement of the articulated arms, that is locked.

This embodiment thus ensures that an unwanted transfer of the side rail from the use position to the non-use position is not possible. Only as a result of a user-side engagement, the locking elements can be converted into their respective non-locking position, which then allows a process of the side rail in the non-use position. As long as the locking elements are in their locked position, a lowering of the side rail, that is, a transfer of the same in the non-use position is suppressed. This is particularly advantageous for safety reasons, since both an unintentional incorrect operation and an otherwise unwanted transferring the side rail is prevented in the non-use position, so that in particular squeezing injuries in the user of the bed and / or side rails are excluded, as they can arise when in the case of a side rail subsidence body parts of the user between the bars of the side rail.

In locking position, the locking elements abut against the respective associated articulated arms, so that a necessary for a transfer of the side rail from the use position in the non-use position pivoting movement of the articulated arms can not take place. In this case, the locking elements lie between the respective associated articulated arms, so that the articulated arms are supported against each other with the interposition of the respectively associated locking element, which blocks the rotational movement of the articulated arms. In a structurally simple manner as already described above blocking function is realized, the inventive design is reliable and robust whether their comparatively simple design in the application.

The articulated arms have, according to a further feature of the invention, projections, that is, projections which cooperate with the associated locking elements and abut against these in the blocking position. The articulated arms thus provide projections, which in turn cooperate with the associated locking element, the projections locking element side provide contact surfaces which rest in the blocking position of the locking element on the locking element, whereby the rotational movement of the articulated arms is blocked. The gelenkarmseitigen projections take in the locked position, the associated locking element between them and thus supported against each other with the interposition of the blocking element from.

According to a further feature of the invention, a blocking element is displaceably mounted and from a blocking position into a non-locking position can be transferred. According to the invention is therefore provided that the blocking element can be moved in translation, which allows to transfer the blocking element from a blocking position to a non-blocking position and vice versa. In this case, the blocking element to release the associated articulated arms is translationally far enough to move that it is no longer in operative connection with the projections of the associated articulated arms. Once this position of the locking element, that is, the non-locking position is reached, the articulated arms can rotate freely, which allows the user side, to transfer the side rail from a use position to a non-use position.

According to a further feature of the invention it is provided that a blocking element is held in the non-use position under a biasing force acting in the displacement direction. In this case, the biasing force ensures that the blocking element is always driven in the direction of its blocking position, which causes an automatic process of the blocking element in its blocking position. The handling safety is increased because it is given by this proviso constructive that the locking elements automatically move into their respective blocking position as soon as the side rails is in its position of use. A transfer of the side rail in the non-use position is permitted only after prior manual actuation of the locking elements by the user. Consequently, a user-side active activation, that is to say transfer of the blocking elements into the non-blocking position, must take place so that then a movement of the side grid into the non-use position can take place.

To produce the biasing force is used according to the invention a compression spring, which is why provided according to a further feature of the invention that a locking element is supported with the interposition of a compression spring on the associated articulated arms. In a transfer of the blocking element in the non-locking position, the compression spring is compressed, that is biased. Once the side rails has been moved from its non-use position into its position of use, the locking element can dive into the then auftuenden gap space between the extensions of the associated articulated arms, so that it already described manner to a concern of the projections on the associated locking element with the result comes that a rotational movement of the articulated arms is blocked relative to each other.

According to a further feature of the invention, it is provided that the blocking element is coupled to a user-operable handle. This handle is used by a user of the bed according to the invention to transfer the associated blocking element from the blocking position to the non-blocking position.

A blocking element is guided according to a further feature of the invention of a spar side bearing. This ensures that the blocking element is securely held on its translational movement path in the direction of displacement and it can not come in relation to one of the pivotable articulated arms to an unwanted blocking position, for example by tilting. The reliability of the construction according to the invention is thus additionally increased.

According to a further proposal of the invention it is provided that the teieskopierbare longitudinal spar has two relatively movable rail sections formed, wherein the einendseitigen articulated arms are arranged on the one spar section and the other end articulating arms on the other spar section and wherein the spar sections provide a volume space, the electromotive Housing drive device, wherein the electromotive drive device cooperates with the two spar sections.

Accordingly, it is provided that the one-end articulated arms, that is, a first pair of articulated arms on the one spar section and the other end-side articulated arms, that is, a second Gelenkarmpaar are arranged on the other spar section. The telescopically formed longitudinal spar thus provides two spar sections available which are arranged so that they can move relative to one another, wherein one spar section carries the first pair of articulated arms and the other spar section carries the other joint arm pair. The spar sections are preferably designed according to the principle of the tubes communicating with each other and provide a volume space. This provided by the spar sections volume space houses an electric motor drive device. This drive device is used to accomplish a telescoping moving apart or driving into each other of the spar sections of the longitudinal spar without manual intervention manual side. For this purpose, it is provided that the electromotive drive device cooperates with the two spar sections. In operation, the drive means drives the telescoping longitudinal spar by the two spar sections of the longitudinal beam relative be moved to each other, either in one another or apart translational process. As a consequence, the side rail is thereby electromotively spent from its position of use in its non-use position or vice versa.

A user-side manual movement of the side rail from a use position to a non-use position or vice versa is not required thanks to the design according to the invention. This happens according to the invention rather by means of the electric motor drive, that is without manual intervention by a user. This allows in a particularly simple manner, an adjustment of the side rail, whether from a use position to a non-use position or from a non-use position into a position of use.

A particular advantage of the electric motor drive device is that it can be remote-controlled, in particular radio-controlled. This allows in particular a nursing staff to be able to accomplish an adjustment of the side grille also from a distance, for example from a remote monitoring and / or control room.

The possibility of remote control but also for a person lying in bed is advantageous because it requires no special effort for the person lying in bed to independently adjust the side rails. This is particularly advantageous if the person lying in bed alone is not able to spend the side rails by means of manual force application from a position of use in a non-use position so as to be able to leave the bed. The remotely controllable electric motor drive device provides a remedy to this extent, that the person lying in bed for the purpose of leaving the bed, the side rails can spend at quasi push of a button from a position of use in a non-use position.

According to a further feature of the invention, it is provided, in particular in combination with the remotely controllable drive device, that the side rail has corresponding sensors which detect the position of the side rail. By means of such sensors it can be determined in particular whether the side rail is in its position of use or in its non-use position. The sensory detected position of the side rail can be transmitted by radio to a central location, For example, be transmitted to a control device in a control and / or monitoring room, so that in particular the caregiver is always informed about the position in which the side rails is located. The nursing staff can therefore be informed immediately when a person lying in bed moves a befindlicher in use position side rails in the non-use position. By providing information about the position of the side railing to the nursing staff, the nurse can react and, for example, provide appropriate assistance to the person lying in bed to make it easier for them to get out of bed.

The electromotive drive device according to a further feature of the invention has a threaded rod. This threaded rod is spent by means of a motor in twisting motion and cooperates with a mating thread, so that in the interaction of threaded rod and mating thread depending on the direction of rotation of the threaded rod collapsing or disengagement of the spar sections of the telescoping longitudinal spar is effected. Such a construction proves to be particularly simple and robust in everyday practical use.

According to a further feature of the invention, it is provided that the drive device is held in the blocking position when it is de-energized. According to this embodiment, it is ensured that, when the drive device is not in operation, an unintentional adjustment of the spar sections relative to one another and thus also an undesired transfer of the side grid from the use position to the non-use position or vice versa is prevented. During normal operation, the drive device is energized. As a result, there is an adjusting movement of the spar sections of the telescopic longitudinal spar, which in turn leads to an adjustment of the side rail. As soon as the desired position of the side rail has been reached by means of the drive device, the drive device is configured, that is to say set without current. In this position, the drive device acts as a blocking member, that is, it blocks an unwanted, for example, manual adjustment movement of the longitudinal members relative to each other. Consequently, it is not possible to accomplish an adjustment movement of the longitudinal spar and thus an adjustment movement of the side rail when the drive device is switched off. This ensures, in particular for safety reasons, that an uncontrolled collapse of the side rail is not possible. This is also true especially in the event of a power failure, ensure that a side rail located in the position of use does not collapse uncontrollably and moves into the non-use position due to gravity.

According to a further feature of the invention, sensors are provided which detect in the position of use of the side rail the space between the upper and lower longitudinal spar on the one hand and lower longitudinal spar and spar on the other hand thereafter, if there is a transfer of the side grid in the non-use position opposing objects and / or body parts are located. Such a sensor detection is used advantageously to limit the risk of injury in the case of operation to a minimum, because it is ensured that activation of the drive means for the purpose of transferring the side rail in the non-use position is only allowed if the space provided by the side rails clearances of objects and / or body parts.

The invention further proposes a side rail with the above-explained side rail features. Such a side rail provides the advantages already vorerläuterten. Thus, in particular the compactness of advantage, as well as the ability to use it in combination with so-called ultra-low beds, as it does not project beyond the lower edge of the bed frame down in its non-use position.

Fig. 1 can be seen in a purely schematic representation of an example of a bed 1 according to the invention. This has in a conventional manner via a bed frame 2, which has two frames 3 in the illustrated embodiment, which extend between two Betthäuptern 5, of which the better overview because of only one in Fig. 1 is shown.

The bed frame 2 serves to receive a lying surface element 4, which is a slatted frame in the illustrated embodiment. This in turn serves to receive a mattress or a cushion element not shown in the figures.

This in Fig. 1 shown bed 1 has a side rail 6, which extends over at least 50% of the extension of the bed frame 2 in the longitudinal direction 7. In the embodiment shown, a side rail 6 is shown. In the intended use case each bed longitudinal side is equipped with a corresponding side rails 6.

The side rail 6 can be transferred from a position of use to a non-use position and vice versa. In the position of use of the side rail 6 it serves as fall protection for a person lying in bed. In the non-use position of the side rail 6 - as in Fig. 1 is shown - is an unhindered entry to bed 1 allowed.

Fig. 2 can be seen in a side view of the side rails 6 according to the invention in the position of use. As can be seen from this illustration, the side rail 6 has two longitudinal beams arranged one above the other in the height direction 8, specifically via an upper longitudinal spar 9 and a lower longitudinal spar 10. The longitudinal bars 9, 10 are movable in the height direction 8, so that the side rails 6 are made the in Fig. 2 shown use position in the in Fig. 1 shown non-use position and vice versa is feasible.

The lower longitudinal spar 10 is formed telescopic. It has two sections 11 and 12, which can be moved relative to each other according to the principle of corresponding tubes. In the exemplary embodiment shown, the first section 11 receives the second section 12 so as to be longitudinally displaceable.

The side rail 6 further has two first articulated arms 14 and two second articulated arms 15.

As can be seen in particular from the presentation Fig. 2 results are on the telescoping, lower longitudinal spar 10 einendseitig and the other end each have a first and a second articulated arm 14, 15 are arranged rotatably. Each longitudinal spar side therefore form a first articulated arm 14 and a second articulated arm 15 a Gelenkarmpaar.

According to the invention, it is provided that the pivot points 17 and 18 of the first and second articulated arm are each arranged at a distance from one another. The first articulated arms 14 are in turn each other end pivotally mounted on the other, that is arranged on the upper longitudinal spar 9, to form a respective pivot point sixteenth

In addition, it is provided that the second articulated arms 15 in turn are each pivotally hinged to a support beam 22 at the other end, with the respective formation of a pivot point 19.

As can be seen from the above explanation, the lower longitudinal spar 10 is equipped in each case with two articulated arms 14 and 15 arranged rotatably thereon, the respective associated pivot points 17 and 18 being arranged at a distance from one another in the vertical direction 8. This spaced arrangement of the pivot points 17 and 18 ensures a coaxial guidance of the sections 11 and 12 of the lower longitudinal spar 10 so that it is not in the intended use in a transfer of the side rail 6 from the use position to the non-use position and vice versa to a canting of the two Sections 11 and 12 to each other.

As can be seen in particular from a synopsis of Figures 5 and 6 results, the articulated arms 14 and 15 carry on its opposite end face of the other articulated arm a tooth contour 27. These tooth contours 27 engage with each other, so that the articulated arms 14 and 15 of Gelenkarmpaars are interlocked. This leads to a positive guidance of the articulated arms 14 and 15 of a Gelenkarmpaars, to the effect that the articulated arms 14 and 15 always rotate at the same angle in a movement of the side rail 6. The articulated arms 14 and 15 of a Gelenkarmpaars are so far motion-synchronized.

As can be seen from a synopsis of the particular FIGS. 1 . 2 and 4 results, pivoted the side rail 6 in the case of actuation in the manner of a concertina. In a transfer of the side rail 6 from the use position according to, for example Fig. 4 in the non-use position according to, for example Fig. 1 Move both longitudinal beams 9 and 10 in the height direction 8 down. As a result of this movement, there is a buckling of the articulated arms 14 and 15, and that is because the lower longitudinal beam 10 retracts telescopically. In the lowered position, like these in Fig. 6 is shown schematically, each fully pivoted articulated arms 14 and 15 are superimposed and take the fully retracted telescopic tube 10 between them.

The upper longitudinal spar 9 is formed in a U-shaped cross-section, with the open side facing the lower longitudinal spar 10. The volume space 20 provided by the upper longitudinal spar 9 serves, in the non-use position of the side rail, to receive the first articulated arms 14 and sections of the lower longitudinal beam 10.

For arranging the side rail 6 on the bed 1 is a support beam 22, shown in the Embodiment is designed as a flat material, as this particular Fig. 3 lets recognize. The support beam 22 provides each end bearing 24 available, which serve to form the pivot points 19 of the articulated arrangement of the second articulated arms.

The front side of the support beam 22 is equipped with an aperture 23 with the interposition of the second articulated arms 15. The support beam 22 and the diaphragm 23 form a volume space 25 between them, in the non-use position of the side rail 6, the second articulated arms 15 dip, as well as the lower longitudinal spar 10 at least in sections, as can be seen from the illustration Fig. 6 results.

The representation after Fig. 6 can further be found that in the non-use position of the side rail 6, the upper longitudinal spar 9 rests on the support beam 22 and provided by the support beam 22 bearing points 24, and this substantially gap-free, wherein the volume spaces 20 and 25, the articulated arms 14 and 15 and the lower longitudinal beam 10 completely record. In that regard, the articulated arms and the longitudinal beam 10 are accommodated in the manner of a cassette arrangement, which is why the side rails 6 according to the invention can also be referred to as a cassette side grid.

The telescopically formed longitudinal beam 10 is equipped with a force accumulator in the form of a tension spring 28. This ensures at a transfer of the side rail 6 from the non-use position into the position of use that a moving apart of the sections 11 and 12 of the longitudinal spar 10 is supported. For this purpose, a lever 29 formed on the inside of the second section 12 is provided, which cooperates with a driver 30 mounted at the end of the spring 28.

In non-use position of the side rail 6, the spring 28 is in a stretched state. If the upper side rail 9 is then grasped on the user side and brought upwards in the height direction 8, then the side rail 6 folds out, as a result of which the lower longitudinal rail 10 is telescoped out. Shortly before reaching the position of use of the driver 30 snaps the end of the lever 29 and causes a spring force induced further movement of the second portion 12 relative to the first section 11, resulting in a transfer of the side rail 6 in the use position in which the articulated arms 14 each at the respective Abut stop 26 of the upper spar 9. In this position of the first section 11 and second section 12 locks the spring button trained locking device 13, as is made Fig. 2 is apparent. In this position, a back process of the side rail 6 in the non-use position can not take place without user-side actuation of the latching device 13.

If the latching device 13 is now actuated on the user side, then a movement movement of the first section 11 and the second section 12 is possible, that is to say the side rail 6 can be transferred from the use position into the non-use position. In this transfer of the side rail 6 in the non-use position, the spring 28 is tensioned, with reaching the spring position, as in Fig. 6 is shown, the lever 29 is disengaged with tensioned spring 28 from the driver 30 and then in the in Fig. 6 shown position is spent.

For arranging the side rail 6 on the bed 1 different embodiments are conceivable, of which three in the FIGS. 7, 8 and 9 are shown.

According to a first embodiment, a connection profile 33 is used to connect the side rail 6 to a frame 3 of a bed frame 2. This has an inner contour which is formed corresponding to the outer contour of the frame 3. The support beam 22 is screwed to this connection profile 33, for which purpose a in Fig. 7 shown bolt 21 is used. The connecting profile 33 is applied to the arrangement on the frame 3 with its upper profile section to the frame 3 and then pivoted clockwise until it rests against the entire surface of the frame 3. Then the grub screw 34 is screwed into the provided by the frame 3 channel 35 for fixing the position. The connecting profile 33 together with side rails 6 arranged thereon is now permanently and reliably mounted on the frame 3.

According to an alternative embodiment, as in Fig. 8 is shown, the support beam 22 may be screwed by means of corresponding bolts 21 directly to the frame 3. In contrast to the embodiment according to Fig. 7 For this purpose, the frame 3 is to be equipped with a corresponding bore through which the pin 21 engages in the final assembled state. Since in the illustrated embodiment, the frame 3 has a curved surface 32 formed, for the purpose of position-safe arrangement of the supporting beam 22 on the frame 3, an adapter element 31 is provided, the frame side has a corresponding to the surface 32 of the frame 3 contour.

According to the embodiment according to Fig. 9 an arrangement of the side rail 6 is not on the frame 3 of the bed frame 2, but on a profile body 36 of the lying surface element 4, that is, for example, a slatted frame. For arrangement on the lying surface element 4, a correspondingly formed carrier beam 22 is used, which overlaps the frame 3 on the upper side. This embodiment has the advantage that the side rail 6 is formed pivotable together with the lying surface element 4, that is, the side rails 6 mitverschwenkt together with an adjustment of the lying surface element 4.

The others FIGS. 10 to 21 show a preferred embodiment of the invention, instead of a locking device 13 has locking elements 37 and 38, which locking elements 37 and 38 in the locked position ensure that the side rails 6 is not unintentionally pivoted from its use position to its non-use position. In this case, each pair of articulated arms a locking elements 37 and 38 is provided, which can be operated on the user side by means of a corresponding handle 43 and from its locked position into the non-locking position. The sectional view after FIG. 14 shows the first blocking element 37 and the second blocking element 38, it being apparent from this representation that the first blocking element 37 cooperates with the articulated arms 14 and 15, which are arranged on one end of the telescoping longitudinal spar 10. The second locking element 38, however, interacts with the articulated arms 14 and 15, which are arranged on the other side of the telescoping longitudinal spar 10.

The articulated arms 14 and 15 each have locking element side via a projection 39 and 40. These projections 39 and 40 cooperate in the blocking position with the associated locking element 37 and 38 together, as shown in particular the illustration FIG. 14 lets recognize. In this blocking position, the respective extensions 39 and 40 abut the respective blocking element 37 and 38, respectively, and are based on this. In this case, the projections 39 and 40 act as an abutment, so clamp in the blocking position the respective associated locking element 37 and 38 between them, as a result of a rotatability of the articulated arms 14 and 15 is prevented with the result that the side rails 6 not from the example in the Figures 10 and 14 shown use position in the example in FIG. 16 shown non-use position can be transferred.

The locking elements 37 and 38 are translationally movable in the longitudinal direction 7, which allows the user side, the locking elements 37 and 38 to proceed accordingly. In this case, the locking element 37 for transfer to the non-locking position with respect to the plane of the drawing FIG. 14 to move to the left and the second blocking element 38 to the right. For this purpose, the blocking elements 37 and 38 are coupled to a respective handle 43 which is accessible from the outside on the user side, as can be seen for example from a synopsis of Figures 10 . 14 and 19 results.

Once the first locking element 37 and the second locking element 38 is transferred from its locked position to its non-locking position, the associated articulated arms 14 and 15 can pivot relative to each other, which allows a transfer of the side rail 6 in the non-use position. FIG. 16 can in this context, the non-use position of the side rail 6 and thus located in non-locking position locking elements 37 and 38 recognize.

The blocking element 37 or 38 has - as in particular the illustration after FIG. 20 This locking body 49 serves the actual Verdrehblockade the articulated arms 14 and 15 and is in the blocking case in the manner already described at the provided by the articulated arms 14 and 15 extensions 39 and 40 at. The locking body 49 and thus also the blocking element 37 is guided by means of a holmseitigen bearing 44, so that the locking element 37 keeps its track in Verfahrfall and not tilted in its relative position relative to the articulated arms 14 and 15.

The blocking element 37 furthermore has a spring receptacle 50, which receives a spring 52 in the final assembled state, by means of which spring 52 the blocking element 37 is prestressed relative to the articulated arms 14 and 15. By means of the spring 52, the blocking element 37 is under a force bias, which causes the locking element 37 is always anxious, according to its blocking position FIG. 20 to proceed.

The spring retainer 50 and the locking body 49 are coupled to each other via a connecting portion 51 which surrounds the pivot-point-side portions of the articulated arms 14 and 15 in the manner of a frame, as can be seen in particular from the sectional view FIG. 19 results.

The above-described construction causes a transfer of the side rail from a non-use position to FIG. 16 in its position of use FIG. 14 the locking elements 37 and 38 each force-induced in the between the respective articulated arms 14 and 15 in the position of use of the side rail 6 resulting gap between the associated projections 39 and 40 dip, as in FIG. 14 shown. Federkraftinduziert is thus effected in a transfer of the side rail in the use position, an automatic transfer of the locking elements 37 and 38 in their respective blocking position.

If now take place a return transfer of the side rail 6 in the non-use position, the user side is first by means of the corresponding handle 43, the locking element 37 and the locking element 38 out of engagement with the projections 39 and 40 of the articulated arms 14 and 15 to bring, so that a Twisting movement of the articulated arms 14 and 15 can take place.

In contrast to the latching device 13 according to, for example FIG. 2 are the locking elements 37 and 38 independently by means of the corresponding handle 43 to solve, that is, there is no simultaneous unlocking of both locking elements 37 and 38 by a common unlocking device instead. This proves to a locking device 13 according to, for example FIG. 2 insofar as advantageous as that it is structurally ensured that a user for the purpose of unlocking the locking elements 37 and 38 does not have his actuating hand between the longitudinal beam 10 and longitudinal spar 9 or longitudinal spar 10 and support beam 22. Thus, the construction proves after the FIGS. 10 to 21 as very safe in handling.

For a pivotable arrangement of the pivot arms 14 and 15 on the longitudinal spar 10 is preferably an articulated arm 48 is used, which adjoins the spar body 45 of the longitudinal spar 10, as can be seen in particular from a synopsis of Figures 18 . 20 and 21 results. In this case, the joint receptacle 48 has two plates 46 and 47 which receive in the final assembled state, the articulated arms 14 and 15 drehverschwenklich between them. The joint receptacle 48 further serves the arrangement of the handle 43, which is in operative connection with the associated locking element 37 and 38, as shown in particular the sectional view FIG. 19 lets recognize.

For the transfer of the side rail 6 from a use position to a non-use position and vice versa can serve an electric motor drive means 53, as can be seen in particular from the illustration FIG. 22 results.

As FIG. 22 can be seen, the telescopic longitudinal spar 10 provides a volume space 56. This volume space 56 serves to receive an electromotive drive device 53, which interacts with the two spar sections 11 and 12. In the operating case, the electromotive drive device 53 ensures that the spar sections 11 and 12 move in the direction of displacement or longitudinal direction 7 relative to each other, that is diverge when transferred to the use position or moved into each other in a transfer to the non-use position. As a result of such a movement movement of the spar sections 11 and 12, there is an elevation of the side rail 6 or to a lowering thereof, depending on the direction of displacement of the spar sections 11 and 12 in the longitudinal direction. 7

In the illustrated embodiment according to FIG. 22 The drive device 53 has a threaded rod 55. This is one end defined by means of a holder 57 relative to the spar section 11, by means of a Verdrehschutzes 58, so that a relative movement between the threaded rod 55 on the one hand and spar section 11 on the other hand is not allowed. At the other end, the threaded rod 55 carries a threaded part 60 carried by a holder 59. The threaded part 60 is able to rotate about the axis of rotation 61 in the direction of the arrow 62, permitting relative rotatability of the threaded part 60 relative to the spar section 12. A movement of the threaded part 60 in the longitudinal direction 7 relative to the spar portion 12 is not possible due to the inclusion of the threaded portion 60 of the holder 59.

The drive device 53 further has a motor 54. This is used in the figures not shown drive the threaded portion 60, wherein a drive of the threaded portion 60 in both clockwise and in the opposite direction is possible, as symbolized by the arrow 62.

In normal operation, the motor 54 is turned on by a user, preferably by means of radio remote control. The motor 54 then drives the threaded portion 60, resulting in that the threaded rod 55 in the longitudinal direction 7 moves relative to the threaded portion 60. Since the threaded rod 55 is fixed at one end to the spar section 11, as a result of this traversing movement of the threaded rod 55, a displacement of the spar section 11 relative to the spar section 12 is effected. The Hofmabschnitte 11 and 12 proceed depending on the direction of rotation of the threaded portion 60 either towards each other or apart. Thus, depending on the user side predetermined direction of rotation of the motor 54 either a transfer of the side rail 6 can be achieved in the use position or in the non-use position.

In one embodiment of the side rail 6 without electromotive drive device 55, the telescopically formed longitudinal spar 10 may be equipped with a force accumulator in the form of a tension spring 28, as already with reference to FIG Fig. 6 described. <U> REFERENCE LIST </ u> 1 bed 18 pivot point 2 bed frame 19 pivot point 3 frame 20 volume space 4 Lying surface element 21 bolt 5 headboard 22 spar 6 side rails 23 cover 7 longitudinal direction 24 depository 8th height direction 25 volume space 9 upper longitudinal spar 26 attack 10 lower longitudinal spar 27 tooth contour 11 first section 28 feather 12 second part 29 lever 13 locking device 30 takeaway 14 first articulated arm 31 adapter element 15 second articulated arm 32 surface 16 pivot point 33 connection profile 17 pivot point 34 grub screw 35 channel 56 Volumersraum 36 profile body 57 holder 37 first blocking element 58 twist protection 38 second blocking element 59 holder 39 head Start 60 threaded part 40 head Start 61 axis of rotation 41 displacement direction 62 arrow 42 compression spring 43 handle 44 camp 45 Holm body 46 plate 47 plate 48 Gelenkarmaufnahme 49 blocking body 50 spring mount 51 connecting portion 52 feather 53 driving means 54 engine 55 threaded rod
