Description

The invention relates to a bed, in particular a hospital and / or nursing bed, with a side rail, which has two height-adjustable longitudinal bars, which are held at one end by means of a provided by a bed head leadership höhenverfahrbar. Furthermore, the invention relates to a side rail for a bed, in particular a hospital and / or nursing bed.

Beds in general, as well as hospital and / or nursing beds in particular are known per se from the prior art, as well as bedside rails.

The purpose of a bedside screen 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.

The previously known from the prior art side rails are usually transferred from a position of use in a non-use position and vice versa. In the non-use position of the side grille the bed entry is possible. The vorerläuterte protective effect results in the use position of the side rail.

A generic bed is from the EP-A-1 817 985 known. This bed is a hospital and / or nursing bed, which is formed in a conventional manner and about two beds and one bed Betthaupte each other has connecting construction.

This from the EP-A-1 817 985 Previous bed has a side rail, which has two in the height direction of the bed stacked longitudinal beams, which are formed adjustable in height. The longitudinal beams are held at one end by a bed head and the other end of a arranged on the bed center post. The mutually facing end faces of the center post on the one hand and the bed head on the other hand are equipped with guide slots into which engage the longitudinal bars each end. The height-adjustable arrangement of the longitudinal bars is realized.

The peculiarity of the construction after the EP-A-1 817 985 is that after lowering the longitudinal beams, that is, after a process thereof in a non-use position of the center post either removed or can be pivoted from its upright position of use in a non-use position. An entry and / or exit to bed is possible so disability-free.

Although the from the EP-A-1 817 985 known design has proven in everyday practical use, it is not free of disadvantages. As a disadvantage, in particular the complex handling is considered, which is necessary to transfer the side rails from the position of use in the non-use position or from the non-use position in the position of use. Because even after a proper lowering of the longitudinal bars in their non-use position is a disability-free access to the bed not yet possible. To achieve this, it still requires the removal or pivoting of the center post. In this respect, the user side a second handling activity is required, which is perceived as cumbersome. Moreover, it is particularly in the case of the removable design of the center post disadvantage that it can be lost. Proper functioning of the side rail is then no longer fulfilled.

Based on the above, it is the object of the invention to provide a bed with a side rail or a side rail for a bed that allows for easier handling.

To solve this problem is proposed with the invention that the longitudinal beams are arranged on the other end pivotally mounted on a support post, wherein the

Support post is telescopically formed and has two sections, wherein the one longitudinal spar is arranged on the one of the two sections of the support post and the other longitudinal spar at the other portion of the two sections of the support post.

The support post is telescopically formed and preferably has an upper, a middle and a lower portion, wherein the one of the two sections serves as the upper portion and the other of the two sections as a central portion.

The side rail according to the invention has two longitudinal beams arranged one above the other in the height direction of the bed. These are held adjustable in height on one end in a guide provided by a bed head. At the other end serves to support the longitudinal beams a support post, which is telescopic and has three inter-movable sections. In this case, provided in the height direction of the bed to Oberst provided longitudinal spar at the upper portion and the other longitudinal spar at the central portion of the support post, namely, pivotally, whereby a Verdrehfreiheitsgrad the longitudinal bars is given to the support post.

The construction according to the invention advantageously allows a simultaneous transfer of both the support post and the longitudinal members arranged pivotally therefrom from the position of use to the non-use position and vice versa. A multiple use, on the one hand to transfer the longitudinal beams and on the other hand, the support post from the use position in the non-use position and vice versa, in contrast to the above-described embodiment of the EP A 1 817 985 not required in an advantageous manner.

The embodiment of the invention makes it possible in a simple manner to transfer the support post from the use position in the non-use position by the individual sections of the support post are telescoped into each other. As a result of this movement follow the longitudinal beams and are thus also transferred from their position of use out in their non-use position.

Telescopically designed support posts for side rail spars are not unknown in the prior art per se. For example, the EP-A-1 623 654 telescopically designed support posts. According to this prior art construction However, each side rails provided two support posts, the one as the other end supporting the longitudinal struts of the side rail. With the embodiment of the invention is compared to this from the EP-A-1 623 654 previously known construction saves a support post per side rails, which simplifies both the production and handling. In addition, the inventive design allows both in contrast to EP-A-1 817 985 as well as in contrast to EP-A-1 623 654 also an inclination of the longitudinal bars of the side rail by the longitudinal bars on the other end supporting supporting post in its non-use position, the longitudinal bars remain relatively unchanged in their leadership relative to the main bed. Such an oblique position of the longitudinal bars can serve, for example, to ensure a security, for example, in particular of the head area of a bed with maximum degree of freedom.

The embodiment of the invention is characterized in particular by its ease of use. In order to transfer the side rail from the position of use in the non-use position, this is only the gravity to lower following, that is, the longitudinal bars of the side rail are following the gravity to move down. The longitudinal beams are held at one end by a guide provided by a bed head. At the other end, the support of the longitudinal bars by a support post, which is retracted telescopically in the course of the transfer from the use position in the non-use position. As a result, a transfer of both the longitudinal bars of the side rail and the support post of the side rail in the non-use position with only a simple downward movement.

The transfer of the side rail from the non-use position to the use position can also be carried out in a simple manner. The in the height direction of the bed to uppermost arranged longitudinal spar is to be taken and to move against gravity upwards. As a result of this movement of the longitudinal spars at the other end supporting supporting post is telescoped apart. The second longitudinal spar is connected to the first longitudinal spar via a drag arrangement, so that it follows the upward movement of the uppermost arranged longitudinal spar. As a result, the side rails are pulled apart in a simple upward movement, whereby it locks after reaching the position of use, so that unintentional lowering is prevented. As a result, so with a only simple handling a complete transfer of the side rail from the non-use position into the use position done.

The longitudinal beams of the side rail are secured in position according to a further feature of the invention, both one end and the other end in their position of use. This position assurance is made for security reasons, in particular to counteract an unwanted transfer of the side rail from the position of use in the non-use position.

The position assurance preferably has a manually releasable latching device. In this case, basically two different alternatives can be provided.

According to a first alternative, the position assurance can be solved by simply pressing the locking device. It can be provided for this purpose trigger means, for example in the form of buttons or switches that release the latching device and thus the secured position of the side rail after a user-side operation. This can then proceed as a result of the influence of gravity without further Hinzutun by the user from the use position in the non-use position.

According to an alternative embodiment, an additional safeguard may be provided in addition to the previously explained first alternative, in particular for the protection of the user. According to this second alternative, a release means is also provided, which releases the latching device and thus the position assurance after a manual operation by the user, but only then - and this is the difference to the first alternative - if the user previously the side rails against the force of gravity slightly raised. A release of the locking device can therefore only take place according to this alternative, when the side rails has been previously raised against the force of gravity, for example by a few millimeters. On the user side, therefore, the side rails must be grasped and raised with one hand, and the release means must be actuated with the other hand, whereby a so-called two-hand operation is provided. Advantageously, operating errors and / or hand clamping or pinching during handling can thus be largely excluded.

The invention further proposes a support post for the single-end support of longitudinal beams of a side rail of a bed which is telescopic and has an upper, a middle and a lower portion, wherein a longitudinal spar at the upper portion and another longitudinal spar at the central portion in each case are arranged, characterized by a tripping element carried by the central portion, which has with its upper portion facing the end portion cooperating with a locking element slide track.

In the use position of the side rail, the individual sections of the support post are secured in their relative position to each other. For this purpose it is preferred to use latching means, i. Locking elements are used, wherein a first locking element blocks the movement of the central portion to the lower portion and a second locking element, the movement of the upper portion to the central portion.

As a result of the operation of the button or switch by a user, the first blocking element is transferred to a release position, as a result of which the middle section together with the upper section arranged thereon can move relative to the lower section. A movement of the upper portion relative to the central portion is not yet possible.

There is provided a triggering element carried by the middle section. This is preferably designed in the manner of a rod and arranged within the preferably hollow executed middle portion of the support post. This triggering element is designed to be movable relative to the central portion and, with its end portion facing the upper portion, provides a slide track which cooperates with the second locking element. The triggering element cooperates insofar with the second locking element, that is to say with the blocking element which, in the blocking position, blocks the relative movement of the upper section relative to the central section.

If, after a proper movement, the middle section reaches its end position relative to the lower section, a relative movement of the trigger element relative to the middle section occurs as a result of the emergence of the triggering element on an abutment provided by the lower section. As a result This relative movement of the trigger element relative to the central portion engages the trigger element with its slide track in a recess provided by the second locking element such that there is a displacement movement of the locking element transversely to the vertical extent of the support post. As a result, the locking element is moved out of its locked position, which in turn causes the movement between the upper portion and middle portion of the support post is released.

The embodiment of the invention is advantageous for several reasons. On the one hand, it is ensured that, even in the case of proper operation of the side rail, the middle section does not move simultaneously relative to the lower section and the upper section relatively to the central section. Rather, initially the middle section with the upper section arranged thereon moves relative to the lower section. As soon as the end position of the middle section is reached relative to the lower section, a movement of the upper section takes place relative to the middle section. In particular, for security reasons, this embodiment proves to be advantageous. For the method of the second locking element, that is the locking element provided between the upper section and the middle section, serves a triggering element which is formed inside the supporting post and automatically causes a triggering when the central section is in its relative position to the lower section in FIG its final position. The trigger element is thus protected from external influences within the support post, whereby the reliability is increased. In addition, the automatic movement of the second locking element allows a simplified handling.

According to a further feature of the invention, it is provided that a longitudinal spar has a preferably sword-shaped carrying element, which serves for the pivotable arrangement of the longitudinal spar on the supporting post, wherein the longitudinal spar is held displaceably in the longitudinal spar direction by the supporting element.

According to this proposal of the invention serves for the rotatable arrangement of a longitudinal spar on the support post a support element. This is preferably designed as a flat material and consists of metal. It may in particular be designed in the manner of a sword.

The support element is arranged pivotably about a pivot point on the support post. In the final assembled state, it engages in a longitudinally displaceable manner in a receptacle provided for this purpose of the associated longitudinal spar. As a consequence, the longitudinal spar is arranged pivotably on the support post, whereby a relative movement between the longitudinal spar on the one hand and the support element on the other hand is possible. This embodiment provides the advantage that a length compensation in a transfer of the longitudinal beams from the use position in the non-use position or vice versa is possible, which allows in particular the already vorerläuterte oblique position of the longitudinal beams.

According to a further feature of the invention it is provided that two side rails of the type described above are provided per longitudinal side of the bed.

Basically, the use of only one side grid is sufficient. Full page safety according to the relevant standard is achieved if the length of the side rail, starting from the head side of the bed, exceeds 50% of the clear bed length. In this respect, a side rail can be provided with an off-center arrangement of the support post, which is considered in accordance with the standard as a full page safety. In order to achieve over the actual clear bed length reaching side rail protection, two side rails can be provided according to the invention, which are arranged successively in the longitudinal direction of the bed. The two side rails can be operated independently of each other, which makes it possible to keep one side rail in the use position while the other side rail is in the non-use position.

It can be provided per side of the bed more than two side rails. Thus, for example, a configuration is conceivable, according to each longitudinal side of the bed three side rails are used, namely a head-side rails, a foot-side rails and a middle side rails. For the middle side rails, a telescoping support post is provided as well as the other end side.

For each side rail, a respective support post is provided which supports the longitudinal members of each side rail each other end side, as explained above.

According to an alternative embodiment, it is proposed in this context that the lower sections of the two support posts to a common lower Section are combined together. This embodiment serves in particular the simplified manufacture and assembly.

According to an alternative embodiment of the invention may be provided in this context to provide a common support post for both side rails. However, a different handling of the two side rails is not possible according to this embodiment. On the other hand, this embodiment allows a simplified handling when both side rails are to be moved as it were.

With the invention, a side rail for a bed, in particular a hospital and / or nursing bed is proposed, which has two height-adjustable longitudinal bars, which are held adjustable in height by means of one provided by a bed head guide, wherein the longitudinal spars are arranged on the other end pivotally mounted on a support post wherein the support post is telescopically formed and has an upper, a middle and a lower portion, wherein the one longitudinal spar at the upper portion and the other longitudinal spar at the central portion of the support post is arranged.

Fig. 1 shows a schematic perspective view of a bed 1 according to the invention.

The bed 1 is designed in a manner known per se. It has a first bed head 2 and a second bed head 3, which are connected to one another via a common frame 41. It is further provided a base 4, which supports the frame 41 vertically adjustable. The frame 41 carries a lying surface frame 5, which is equipped with slatted slats and the inclusion of a in the Fign. Bed mattress not shown in detail serves.

The in Figs. Bed heads 2 and 3 shown represent a head part (bed head 2) on the one hand and a foot part (bed head 3) on the other hand. The bed heads each provide a guide 20 for the longitudinal struts of a side rail per longitudinal side. In this respect, the bed head in the context of the invention, a different than in the Fign. shown construction, wherein it is only important that respective guides are provided per longitudinal side. As a bed head in the context of the invention, therefore, a respective guide providing posts can be considered, each longitudinal side of a post is to be formed. This post forming a bed head can also be designed to be telescopic.

The bed 1 has a total of three side rails, namely the side rails 6, the side rails 10 and the side rails 11th

The side rails 6 has two in the height direction 9 of the bed 1 arranged one above the other longitudinal beams 8 and 9. These are on as the other end in guides of the bed main 2 and 3 guided adjustable in height, so that they from their in Fig. 1 shown use position can be converted into a non-use position. The side rail 6 is known in its embodiment shown in the prior art.

The side rail 6 opposite other longitudinal side of the bed 1 is equipped with two side rails 10 and 11 according to the invention, which are formed successively in succession in the longitudinal direction of the bed.

The side rail 10 has two longitudinal bars 12 and 13, which are held at one end by means of a provided by a bed head 3 guide vertically movable and the other end are pivotally mounted on a support post 14. The side rail 11 is configured in a comparable manner and has two longitudinal bars 15 and 16, which are held at one end by means of a provided by a bed head 2 guide 20 höhenverfahrbar and other ends are pivotally mounted on a support post 17.

The support posts 14 and 17 of the side rails 10 and 11 are each formed telescopically and have a lower portion 25, a middle portion 26 and an upper portion 27, as can be seen in particular from the illustration Fig. 5 based on the support post 14 shown here results.

With respect to the height direction 9 of the bed 1 is below the longitudinal beams 15 and 12 of the side rails 10 and 11 are each a facing 18 and 19, respectively, arranged on the frame 41 of the bed 1. This veneer serves to block the clear view of the frame 41 of the bed 1. In a horizontally oriented lying area frame 5 close the panels 18 and 19 with its upper edge above the lying surface frame 5 from.

The support end 14 provided for the other end support of the longitudinal beams 12 and 13 of the side rail 10 is shown in detail in the FIGS. 5 to 8 shown. The support post 17 of the second side rail 11 is configured in a mirror-inverted manner.

The support post 14 consists of the three sections 25, 26 and 27. These sections are preferably formed as a hollow profile body and may for example consist of aluminum. The upper portion 27 is telescopically movable relative to the central portion 26, which in turn is telescopically movable relative to the lower portion 25. Fig. 5 shows the support post 14 in the extended position, whereas Fig. 6 the retracted position, too Called non-use position, shows.

For pivotable arrangement of the longitudinal beams 12 and 13 on the support post 14 serve the support members 29 and 30. These are each trained like a sword and hinged to the support post 14, wherein the support member 30 for the height direction 9 of the bed 1 upper longitudinal beam 13 at the upper portion 27 of Support post 14 and the support member 29 is arranged for the longitudinal beam 12 at the central portion 26 of the support post 14.

For the articulated arrangement of the support member 30 on the support post 14 is a cap member 28 which protrudes with a support post-side extension in the space provided by the upper portion 27 of the support post 14 cavity. The cap member 28 is preferably formed of plastic.

The longitudinal beams 12 and 13 are each at the other end attached to the support members 29 and 30, wherein in the intended use in the longitudinal direction of the longitudinal beams 12 and 13 relative displacement of the longitudinal beams 12 and 13 relative to the respective support members 29 and 30 is possible. This longitudinal displacement option is used for length compensation.

In order to ensure a telescoping extension and retraction of the support post 14 at connected longitudinal beams 12 and 13, the sections 25, 26 and 27 of the support post 14 with corresponding slots 31, 32 and 40 are provided. These slots 31, 32 and 40 ensure on the one hand a displacement movement in the height direction 9 and on the other hand a rotational movement of the support elements 29 and 30 relative to their respective sections 26 and 27th

The support post 14 is in its extended position, that is in its position of use according to Fig. 5 secured in position. To cancel this position fuse a trigger element 23 is provided. The support post 17 has a triggering element 24 in a corresponding manner.

As can be seen in particular from a synopsis of FIGS. 7 and 8 results, the manually actuated by an operator trigger element 23 cooperates with a release pin 38 which in a bearing portion 39 of a plug 36 of the central portion 26th is guided. The plug 36 is preferably formed as a one-piece injection molded part.

The upper portion 27 of the support post 14 is also closed at its end remote from the cap member 28 with a plug 35. This stopper 35 provides a recess 37 formed in the manner of a long hole, which is formed corresponding to the bearing section 39 of the stopper 36. This embodiment has the advantage that a sufficiently low height of the support post 14 is realized, with simultaneous lateral stability in the extended position, which is determined by the overlap region of the individual sections in the vertical direction.

The operation of the side rail 10 or 11 according to the invention results in particular from the illustrations according to the FIGS. 1 to 4 ,

These leave in the FIGS. 1 and 2 the side rails 10 and 11 each recognize in the use position.

To transfer the side rails 10 and 11 in their respective non-use position, the respective longitudinal beams 15 and 16 or 12 and 13 to proceed, as exemplified by the side rail 11 in the FIGS. 3 and 4 is shown.

As a result of an actuation of the trigger element 24, the support post 14 can be retracted telescopically. As a result, the longitudinal beams 15 and 16 are moved to the other end down in the non-use position. It results in the Fig. 3 shown inclined position of the side rails 15 and 16th

Einendseitig the longitudinal beams 15 and 16 are held in the guide 20 of the bed main 2. Preferably, a position assurance is also provided here, which can be unlocked by means of an actuating element 21. As a result of such unlocking process the longitudinal bars 15 and 16 einendseitig in the guide 20 of the bed head 2 of the weight following down, so that finally the in Fig. 4 shown position of the side rail 11 results in which this is in the non-use position, so that an unhindered entry and exit to the bed 1 is possible.

The in the FIGS. 3 and 4 shown as a two-stage movement transfer of the Side rail 11 from the position of use after Fig. 2 in the non-use position after Fig. 4 can of course also be carried out in one stage. For this purpose, a user grasps the longitudinal spar 16 of the side rail 11 which is upper in the height direction 9 of the bed 1. The actuating element 21 and then the release element 24 are then actuated with the other hand. The operation of these elements can of course also be done in reverse order. Once, in any case, after actuation of the trigger element 24 and the actuator 21, the corresponding position fuses are solved, the longitudinal beams 15 and 16 of gravity following the procedure below, where they are guided at one end in the guide 20 of the bed main 2 and the other end of the longitudinal beams 15 and 16 supporting support post is retracted.

A transfer of the side rail 10 from the position of use in the non-use position takes place in the same manner as above with reference to the side rail 11 exemplified, here to cancel the position assurance, the actuator 22 and the trigger element 23 are to be operated on the user side.

In the non-use position, the longitudinal beams 15 and 16 of the side rail 11 or 12 and 13 of the side rail 10 are with respect to the viewing direction Fig. 2 . 3 and 4 in each case in front of the associated veneers 18 and 19, such as in particular a synopsis of FIGS. 2 and 4 lets recognize.

The execution of the support post 14 after the FIGS. 7 and 8 illustrates a first embodiment. After actuation of the trigger member 23 moves - as already described above - the middle portion 26 together with the upper portion 27 relative to the lower portion 25. The upper portion 27 is held opposite the central portion 26 by a blocking element , Only when this is transferred to the release position, the upper portion 27 can be moved relative to the central portion 26.

The blocking element which couples the upper section 27 to the central section 26 has a pin 56. In the position of use, the pin 56 extends through a bore formed in the wall of the central section 26. In this position, as in FIG. 7 is shown, a method of the upper portion 27 relative to the central portion 26 is not possible.

If the triggering element 23 is now actuated, then the middle section 26 moves downwards in the height direction 9. Shortly before reaching its end position relative to the lower portion 25 of the pin 56 reaches the provided by a guide insert 42 peripheral edge 57. Following the weight force of the middle portion 26 and the upper portion 27 press in the height direction 9 further down, as a result, the pin 56 of the peripheral edge 57 is displaced in the transverse direction 55, that is, with respect to the plane of the drawing FIG. 7 to the right. As a result of this sliding movement, the locking element is released, which couples the upper portion 27 with the central portion 26, so that after pressing the pin 56, the upper portion 27 can move relative to the central portion 26.

The above-described embodiment has proven itself in practice. However, it is not free of disadvantages, and that is not because it comes to a wear-related wear of the peripheral edge 27 even when used as intended, namely the fact that at a transfer of the side rail from the use position in the non-use position of the pin 56 at this Rim 57 supported. After prolonged use, the functionality may therefore be disturbed.

To overcome this disadvantage, the invention proposes a second embodiment. This is in FIG. 8 shown. According to this embodiment, a trigger element 49 in the form of a rod is used. This triggering element 59 cooperates with a blocking element 44 in the form of a locking bolt. In this case, the locking bolt is the blocking element which serves to block the movement of the upper portion 27 relative to the central portion 26.

As the representation after FIG. 8 can be seen, in the middle section 26 on top of a guide insert 43 is inserted. This serves the leading intake of the upper portion 27th

The upper portion 27 points with respect to the plane of the drawing FIG. 8 on the underside of the locking element 44. This is arranged displaceably in the transverse direction 55 in a sleeve, wherein it is supported with the interposition of a spring 47 relative to the upper portion 27. On the spring 47 opposite side of the upper portion 27 is provided with a recess 28 which projects through the locking element 44 in the case of locking. The blocking element 44 carries an extension 45 at the end.

This cooperates with a recess 26 of the central portion 26 and engages in this in the locked state. The spring 47 ensures that the blocking element 44 is attempting to move into the blocking position, according to which the blocking element 44 engages with its extension 45 into the recess 46 of the middle section 26. In this position, the upper portion 27 is locked relative to the central portion 26, so that a movement of the upper portion 27 relative to the central portion 26 is not possible.

To unlock the locking member 44, that is, to move the locking member 44 in the unlocked position, as in FIG. 8 This has in the end region 52 which is assigned to the upper portion 27, via a mandrel 53. This is about to form a slide track 54 in the actual body of the trigger element 49 via. The end portion 52 cooperates with the blocking element 44 by immersing it in an opening 48 provided by the blocking element 44.

At the other end, ie with the end region 50, the triggering element 49 cooperates with a bottom plate 51 of the plug 36. In this case, the trigger member 49 is supported against the bottom plate 51, which serves as an abutment.

The bottom plate 51 has an opening 59 through which a projection 60 engages when the middle portion 26 is in the non-use stellung in its end position relative to the lower portion 25. The extension 60 passes through the opening 59 in this position and acts on the trigger elements 49 against a spring force, as a result of which the trigger element 49 is displaced in the vertical direction 9 upwards. As a result of this sliding movement provided by the trigger member 49 slide link 54 and the opening 48 of the locking member 44 cooperate such that the locking element 44 is displaced in the transverse direction 55, that is, with respect to the plane of the drawing FIG. 8 to the right. As a result, the upper portion 27 is released relative to the central portion 26, which allows a movement of the upper portion 27 relative to the central portion 26 in the height direction 9 down.

If the support post 14 is transferred from the non-use position to the use position, the upper section 27 moves by lifting the side rail first relative to the central portion 26. As soon as the end position is reached then moves the middle portion 26 relative to the lower portion 25. As a result, the trigger element 49 is no longer and can be relatively moved relative to the central portion 26 due to the acting spring force. The end portion 52 of the trigger member 49 thereby becomes with respect to the plane of the drawing FIG. 8 moved down so far that only the mandrel 53 is in the opening 48. Due to the spring force acting on the blocking element 44, the latter can now travel to the left in the transverse direction 55, so that an automatic "snapping in" of the blocking element 44 with the extension 45 takes place in the recess 46 provided for this purpose.
