Description

The invention relates to a side rail for a bed, in particular for a hospital and / or nursing bed.

Side rails for beds in general and side rails for hospital and / or nursing beds in particular are known from the prior art as well as beds as such, for example US 4752977 where a height-adjustable side rail is mounted at both ends.

Side rails serve as a rule to be able to lock the long sides of a bed if necessary, especially to prevent people lying in bed from accidentally falling, for example, during sleep from the bed. Here, especially in hospitals and / or care beds side rails in a variety of configurations use.

There are also known side rails, which are designed as spars and einwie otherend end to the respective associated end portion of the bed, d. H. the head end part on the one hand and the Fußendteil on the other hand are arranged. Such previously known side rails can be designed to be displaceable in the vertical direction.

Furthermore, side rails are known from the prior art, which are arranged on the bed and / or support frame of the bed and designed to be pivotable about a pivot axis extending transversely to the longitudinal extent of the bed.

If necessary, such configured side rails can be pivoted from its non-use position to its position of use, d. H. be worked out.

Although the previously known from the prior art side rails for beds have proven in everyday practice, there is room for improvement. It is therefore the object of the invention to propose a novel ausgestaltetes side rails.

To solve this problem, the invention proposes a side rail for a bed, in particular for a hospital and / or nursing bed, which is mounted at one end vertically displaceable on a supporting post of the bed and the other end is freestanding.

The side rails according to the invention is designed in the manner of an armrest, which is free-standing at one end. At the other end, the side rail is mounted vertically displaceably on a support post of the bed, for example a support post of a bed end part.

In contrast to known from the prior art side rails the side rails according to the invention is not formed on both sides, but only one end, which advantageously creates additional uses. Thus, the side rails according to the invention can be moved, for example, with a handle and thus in a simple manner in the desired altitude. In a bed equipped, for example, with up to four side rails of the type according to the invention, the individual side rails can be height-adjusted independently of one another.

A side rail according to the invention preferably has a displacement device and a spar arranged thereon. The displacement device serves the height-displaceable arrangement of the side rail on a support post. Preferably, the spar is arranged rotatable and / or displaceable on the displacement device. In the case of a corresponding position of the spar to be adjusted by the user as desired relative to the displacement device, it is advantageously possible to use the side mesh also as an armrest, storage possibility or the like. In addition, one in such Way ausgestaltetes side rails are pivoted for the purpose of simplified entry into bed in the manner of a door or gate, which simplifies handling altogether.

According to a further feature of the invention, the spar can be made telescopic in the longitudinal direction. This embodiment makes it possible to extend the side rails in the longitudinal direction of the same and thus to extend. It can be provided, for example, that the spar of the side rail is hollow and receives a longitudinally displaceable guided extension section. This extension portion can be moved relative to the spar and moved out of this or into it. The spar and the extension portion are preferably matched with respect to the dimensions of the bed in the longitudinal direction such that at fully extended extension portion at least 50%, preferably at least over 50%, for example 51% or 52% of the longitudinal extent of the bed are covered. With a cover of at least 51% of the longitudinal extent of the bed through the side rails can be spoken of a "closed" bedside. Should be provided on the opposite ends of a bed side rails, it is preferred that they are coordinated so that they do not abut each other at maximum displaced extension section, but that at least one of the two side rails at fully extended extension section 51% of the associated longitudinal side of the Bed covers. According to this particular embodiment of the invention, the other side rail of a longitudinal side, ie the one which does not cover 51% of the associated longitudinal side of the bed even when the extension section is fully extended, can be designed as a side rail which is easily interchangeable on the bed in the sense of retrofitting.

According to a further feature of the invention, the displacement device has a hand-operated locking. By means of this locking the side rails can be locked in position relative to the support post, wherein in the locked position of the side rail an unwanted vertical displacement of the same is prevented. The lock is preferably designed to trigger automatically and can be solved by hand. The automatic release of the lock can be ensured for example by a spring element or the like.

The displacement device may have guide rails. In the intended, final assembled state of the side rail, these guide rails engage in a guide provided by the associated support post of the bed. The guide rails can slide within these guide grooves, which allows a simple and little effort required making height displacement of the side rail. In addition, due to the guide grooves-guide rail arrangement with respect to the height extent of the bed twist-proof, d. H. Tilting friendly arrangement of the side rail on the support post ensured, which is not least for safety reasons beneficial.

According to a further feature of the invention, at least one of the guide rails on a position limiter. This can for example be designed in the form of a pin in the manner of a cam and engage in the guide rail associated guide. Within the guide stops are provided, against which the position limiter can counter, so that too far up or too far down sliding the side rail is effectively prevented.

The invention further proposes a bed, preferably a hospital and / or nursing bed, which has a side rail of the type described above.

Fig. 1 shows a schematic representation of the end portion 33 of a better clarity in the figures because of the bed, not shown. The end portion 33 may be, for example, the head end portion or the foot end portion of a bed. Usually extends between the head end part on the one hand and the Fußendteil other hand, for example, the bed mattress receiving mattress surface. For the sake of clarity, the illustration of these components in the figures has been omitted.

As Fig. 1 can be seen, at the end portion 33, a side rail 1 of the invention arranged in a height-adjustable manner. The side rails according to the invention is at one end mounted vertically displaceable on a support post 34 of the end portion 33, in the height direction 32. At the other end, ie the support post 34 opposite the side rails 1 is formed freestanding. "Freestanding" in the sense of the invention means that the side rails on the other side is not stored or otherwise held. The side rail 1 is the other end formed rather free standing in the room.

The side rail 1 according to the invention is in the FIGS. 2 and 3 shown in more detail. As these figures show, the side rail 1 has a displacement device 2 and two spars 3 and 4. The spars 3 and 4 are connected in the mounted state of the side rail 1 with the housing part 9 of the displacement device 2, for example screwed. For this purpose, the housing part 9 has corresponding threaded domes 23. The spars 3 and 4 have corresponding holes 24 through which pass in Fig. 2 respectively. Fig. 3 not shown screws out and screwed in the final assembled state in the threaded mandrel 23.

According to a preferred and in the FIGS. 2 and 3 illustrated embodiment is further a mounting plate 6 is used, which also has holes for passing through the fastening screws, not shown in the figures, via the bores 25th

The spars 3 and 4 are, in particular Fig. 2 can recognize, designed as hollow profiles. In the assembled state, a conclusion 5 is pushed onto the spars 3 and 4 the housing part 9 of the displacement device 2 opposite, which is formed in the illustrated embodiment, U-shaped. The conclusion 5 has for a preferably formed as a clamping connection with the bars 3 and 4 via pins 7 and 8, which are received in the final assembled state of the hollow sections 3 and 4 provided as hollow profiles volume spaces. According to an alternative embodiment of the invention can also be provided that the pins 7 and 8 are each formed as extension cuts and are telescopically received by each provided by the bars 3 and 4 volume space. According to this alternative embodiment, it is then possible to move the closure 5 relative to the spars 3 and 4, in the longitudinal direction of the spars 3 and 4. In such an embodiment, the closure 5 can be guided by the spars 3 and 4 in the longitudinal direction of Spars 3 and 4 can be moved to extend the side rails, for example, if necessary. The length of the spars 3 and 4 or the length of the pins 7 and 8 are preferably coordinated such that at fully extended conclusion 5 the side rails in the longitudinal direction has such an extent that preferably 51% of the long side of the bed are covered, so that the bed with respect to this long side can be considered "closed". In order to prevent the conclusion 5 inadvertently pulled too far with its pins 7 and 8 from the bars 3 and 4, may be provided according to a proposal of the invention that at least one of the spars carries a retaining device, which ensures that the associated Pins can not be pulled out of the spar unintentionally.

The FIGS. 4 and 5 show the displacement device 2 of the side rail according to the invention in each case in a detailed view. It can be seen here that the displacement device 2 has a housing part 9. In the final assembled state 9 guide rails 10 and 11 are used in this housing part, which are bolted to the housing part 9, for example, for which purpose the housing part 9 has corresponding threaded bosses 30 and 31 has. The guide rails 10 and 11 accordingly have through holes 28 and 29 through which fastening screws can be passed.

The displacement device 2 further has a lock 12, which may also be connected to the housing part 9, for example by appropriate screwing. For this purpose, the thread roots 26 are formed on the housing part. The lock 12 has corresponding holes 27. The lock 12 has a spring-hinged arm 13, which has a pin-shaped cam 14. In a locked position of the side rail 1, the cam 14 of the lock 12 engages in a formed on the support post 34 recess 43, as for example in Fig. 1 can be seen. If the side rail 1 is in a locked position, ie if the cam 14 of the lock 12 engages in a recess 43, an unintentional displacement of the side rail 1 in the height direction 32 is not possible. In order to solve the lock, it requires the operation of the handle 15 of the displacement device. 2

The handle 15 includes, in particular Fig. 5 can be removed, two arms 17 and 18, an actuating portion 19 and two receptacles 21 and 22. In the final assembled state, the receptacles 21 and 22 surround a formed in the housing part 9 of the displacement device 2 axis 20, which a rotational movement of the handle 15 relative to the housing part 9 of the displacement device 2 allows. In this case, the arms 17 and 18 of the handle 15 in the final assembled state of the side rail 1 embrace the resilient arm 13 of the lock 12. Due to this configuration, it is possible against the spring force of the arm 13 by means of an actuation of the handle 15 via the operating portion 19 Arm 13 of the lock 12 such deflect that the cam 14 of the arm 13 is disengaged from a recess 43. When the cam 14 is out of engagement with a recess 43, the side rail 1 in the height direction 32 relative to the support post 34 can be moved vertically.

This in Fig. 1 shown end portion 33 has with respect to the drawing level after Fig. 1 On the left side via a support post 34 and on the right side via a support post 35. Between the two support posts 34 and 35, a plate 36 is arranged, as for example, in Fig. 6 can be seen.

The fragmentary in the FIGS. 6 and 7 Support post 34 shown consists of a profile part 37. This profile part 37 provides two guide grooves, namely the guide grooves 38 and 39 are available. In these guide grooves engage in the final assembled state of the side rail 1, as in Fig. 1 is shown, provided by the displacement device 2 of the side rail 1 guide rails 10 and 11 a. In this case, the guide rail 10 engages in the guide groove 38 and the guide rail 11 in the guide groove 39.

With reference to the drawing plane Fig. 6 the profile part 37 forming the support post 34 is closed on the upper side by means of a closure part 44. When removed closure member 44, as shown in Fig. 6 2, the displacement device 2 of the side rail 1 can be threaded into the guide grooves 38 and 39 provided by the profile part 37, and the side rail 1 can thus be arranged on the end part 33.

The connecting part 44 has, in particular Fig. 6 can be removed, via an extension 41. This extension 41 is used for the arrangement of, for example, a terminal spar 42, as this best Fig. 1 can be seen. The end spar 42 extends with respect to the plane of the drawing Fig. 1 above the plate 36 and secures the two end portions 44 of the support post 34 on the one hand and the support post 35 on the other hand against each other. How out Fig. 6 or off Fig. 7 can be seen further, the closure member 44 is closed on the upper side by means of a cap 40.

Fig. 8 shows in partially detailed detail the design Fig. 1 in a rear view. It can be seen here that the side rail 1 is locked in the lower position. The cam 14 of the lock 12 passes through the recess 43. A displacement of the side rail 1 in the vertical direction is therefore possible only after a previous solution of the lock 12 by the handle 15.

The representation after Fig. 8 can be further seen that the arranged on the guide rail 10 position limiter 16 abuts the stop 45. Another move down the side rail 1 is therefore not possible.

As the representation after Fig. 8 further reveals that the support profile 34 forming profile part 37 is mounted on a connecting part 46. On the one hand, a Wandabweisrolle 47 and on the other hand, a footrest 48 is connected to the connecting part 46. The footrest 48 extends, in particular Fig. 1 can be removed, almost parallel to the end spar 42, with respect to the plane of the drawing Fig. 1 below the plate 36 between the two support posts 34 and 35th

Too much shifting of the side rail 1 is as based on Fig. 8 explained above, not only down, but also limited to the top. As a stop for the position limiter 16 serves the example in Fig. 6 shown closure member 44 which has a corresponding recess 49 for receiving the position limiter 16 in the upper position.

As the above explanation with reference to FIGS. 1 to 8 has shown, the side rail 1 is characterized in that it is designed to be vertically displaceable, in such a way that it endend mounted höhenverschiebbar at the end of the bed, on the other hand, however, is designed freestanding. <U> REFERENCE LIST </ u> 1 side rails 18 poor 2 shifter 19 actuating section 3 Holm 20 axis 4 Holm 21 admission 5 Graduation 22 admission 6 mounting plate 23 threaded dome 7 spigot 24 drilling 8th spigot 25 drilling 9 housing part 26 threaded dome 10 guide rail 27 drilling 11 guide rail 28 drilling 12 lock 29 drilling 13 poor 30 threaded dome 14 cam 31 threaded dome 15 handle 32 height direction 16 position limiter 33 end 17 poor 34 support post 35 support post 36 plate 37 profile part 38 guide 39 guide 40 cap 41 extension 42 close Holm 43 recess 44 closing part 45 attack 46 connector 47 Wall protection 48 base beam 49 recess
