Definitions
- Bed in particular patient and / or nursing bed and length-adjustable support element for such a bed
- the invention relates to a height-adjustable bed, in particular a hospital or nursing bed, and moreover to a length-adjustable support element which can be used as a pillar for a bed.
- Height-adjustable hospital and / or nursing beds are known, for example, from DE-C-39 40 666 and DE-A-44 05 509. Both known beds are provided with a lifting base, which has four legs connected to each other by connecting struts. Each supporting leg has a running and / or steering roller at its lower end. When the base frame is fully retracted, these rollers are free so that the bed can be moved. If, on the other hand, the underframe is extended, the lower legs of the bed according to DE-C-39 40 666 stand on the ground with their lower ends, while the rollers on the bed according to DE-A-44 05 509 are braked. In both known beds, when the underframe is moved out of its lowest lifting position, it is no longer possible to move the bed.
- the bed In order to increase the comfort of a hospital and / or nursing bed, it is sometimes required that the bed can be lowered relatively low so that the patient can rise comfortably from the edge of the bed or can comfortably sit on the bed edge. On the other hand, the bed should also be able to be raised relatively high in order to be able to be moved to a comfortable working height for the sick and / or nursing staff.
- the main pillars of the well-known care beds cannot be extended and retracted far enough to fully meet these requirements.
- the invention has for its object to provide a bed, in particular a hospital and / or nursing bed and a length-adjustable support element that can be used as a mainstay in such a bed and that can be extended and retracted relatively far with a small overall height.
- the invention proposes a variable-length support element for use as a supporting leg for a height-adjustable bed, in particular a hospital and / or nursing bed, which is provided with a supporting leg, a supporting leg which has a supporting edge at its lower end, a caster and / or steering roller, which has a tread and is received by the support leg, the roller being movable for movement from the lower end of the support leg beyond its edge and into the lower end of the support leg, and - one from the Lifting device movable out of the upper end of the supporting leg and movable into the upper end of the supporting leg, which has a supporting element which can be attached to a first element of an object to be supported by the supporting leg.
- the lifting device has a double spindle arrangement which has an inner spindle and a hollow spindle receiving the same, that the double spindle arrangement can be brought into engagement with a drive element which can be driven by a drive device which can be attached to the support element or the first part of the object is that the inner spindle is in threaded engagement with the hollow spindle and the
- Hollow spindle is in threaded engagement with the supporting leg and that the double spindle arrangement cooperate with the holding element of the roller in such a way that the running surface of the roller is moved into a maximum stroke position of both spindles with respect to the supporting edge of the supporting leg or is flush with the supporting edge of the supporting leg, that the running surface of the roller in a minimum stroke position of both spindles is aligned with the standing edge of the supporting leg and that the running surface of the roller in a minimum retracted position of both spindles, in which they are moved further into the supporting leg beyond the minimum lifting position than in their minimum lifting position, over the Stand edge of the leg protrudes.
- the lifting device is designed as a double spindle arrangement which has two spindles which can be pushed axially into one another and are in threaded engagement with one another.
- the inner spindle can be driven in rotation by a drive device.
- the inner spindle rotates into and out of the second spindle designed as a hollow spindle.
- the hollow spindle itself is in threaded engagement with the main leg.
- the double spindle arrangement and the holding element for the roller are arranged in such a way that the running surface of the roller in a maximum stroke position of the double spindle arrangement is moved into the standing edge of the standing leg or is flush with the standing edge of the standing leg.
- the running surface of the roller In a minimum stroke position of the double-spindle arrangement, the running surface of the roller is aligned with the standing edge of the supporting leg; in other words, the roll does not protrude down over the edge of the pillar. If the double spindle arrangement coming from the direction of the maximum stroke position is moved beyond the minimum stroke position into a minimal retracted position into the supporting leg, the running surface of the roller protrudes beyond the standing edge of the supporting leg.
- This mechanism according to the invention can be realized on the one hand by the fact that the holder of the roller is fastened to the hollow spindle or the inner spindle and consequently moves with it through the supporting leg, which is dependent on the respective stroke position of the double spindle arrangement.
- An alternative to this concept is to mount the support of the roller so that it can move in the axial direction of the support leg at its lower end without the holding element being fixed to the double spindle arrangement connected is. If the two spindles are arranged in a telescopic tube with at least two tube sections, it is also possible that one of the two or both tube sections comes into contact with the holding element of the roller as it approaches the minimum retraction position and for its disengagement via the lower end of the mainstay.
- a support element which can be extended to a maximum stroke dimension with a small overall height, in addition to which the function of automatically fixing the object held by the support element against travel movements and automatically canceling this determination for moving the object is integrated are.
- the lifting device has at least one tube section that can be telescoped with the supporting leg, which is attached to the fastening element and coaxially surrounds the double spindle arrangement.
- This at least one pipe section is guided on the pillar. Purpose- moderately, two or more such tube sections are used, which can be pushed into one another like a telescope, the lowest tube section facing the support leg being guided on the support leg and being telescopic with it.
- the support element according to the invention it is expedient to provide at least two tube sections which can be telescoped with one another and with the supporting leg and cover the double-spindle arrangement. So that the pipe sections can be moved as far as possible into the supporting leg and thus the axial overall height of the supporting element is minimal, it is advantageous if the roller is arranged in a frustoconically shaped insert which is inserted into the lower end of a pipe forming the supporting leg is.
- this insert runs at an acute angle to the wall of the supporting leg tube, so that the tube section (s) in the minimum stroke position or the minimum retracted position of the double spindle arrangement can be immersed in the space between the insert part and the supporting leg tube that tapers towards the end of the supporting leg tube .
- the insert With its end arranged at the lower end of the supporting leg, the insert forms the standing edge of the supporting element and is required to hold and support an inner tube which is arranged coaxially to the supporting leg tube and which is in threaded engagement with the hollow spindle.
- the roller With a firm connection to the hollow spindle or the inner spindle, the roller can now be displaced through an opening in the upper end of the insert part facing away from the lower end of the supporting leg when the stroke position of the double spindle arrangement changes.
- the holding element of the roller is axially displaceably mounted in the upper end of the frustoconical insert, so that the double spindle arrangement in the manner described above with this holding element for the purpose of moving the same to move the roller out of the lower end of the mainstay interacts.
- a deflection roller is arranged at the upper end of the inner spindle, around which an endless drive process is shown Form a chain, a toothed or V-belt is guided around.
- a belt drive is driven by the drive device and can simultaneously drive one or more deflection rollers and thus inner spindles.
- the pairs on the head side and on the foot side could be driven separately from the legs by a belt drive each; alternatively, the double spindle arrangements of all four legs can be driven by a common belt drive.
- a toothed belt with gears meshing with these is advantageously used as deflection pulleys as the belt drive.
- the support element according to the invention has a first limit switch, one of two switching states of which signals that the maximum stroke position has been reached.
- This maximum stroke position could be determined in a one-part cladding telescope tube by querying the relative axial position of both tube sections of the telescope.
- a three-pass telescopic telescopic tube is used, the supporting leg tube forming one of the three tube sections that can be telescoped with one another.
- a first actuating element which actuates the first limit switch, is mounted on the supporting element supporting the object to be supported between a first position and a second position. stored away.
- the first actuating element is prestressed into the first position by means of a prestressing force.
- a traction element Connected to the first actuating element is a traction element, the other end of which is fastened to an anchoring element, which in turn is arranged immovably relative to the supporting leg.
- the anchoring element is expediently fastened to the support leg tube or, if present, to the inner tube arranged coaxially to it and receiving the double spindle arrangement.
- the anchoring element is located in the space between the inner tube and the leg tube. If the double-spindle arrangement is now extended and moved into its maximum stroke position, the pulling element exerts a pulling force on the actuating element when the maximum stroke position is reached, which is consequently moved from its first position against the biasing force into its second position. The switching state of the first limit switch changes so that reaching the maximum stroke position is indicated electrically.
- the traction element can be, for example, a traction rope, a chain or the like. act, which or conveniently winds up automatically when retracting the double spindle assembly in the main leg and thus shortens. A winding device is then required for this. This is relatively expensive. It is therefore more favorable if the pulling element is designed in the manner of a telescopic rod with an inner rod and an axially leading outer rod, one of the two rods being connected to the first actuating element and the other being connected to the anchoring element. The telescopic rod steers by pulling the inner rod out of the outer rod until it has reached its maximum length.
- the pull rod acts on the first actuating element when the maximum lifting position is reached, in order to move it relative to the supporting element against the pretensioning force into the second position.
- the telescopic rod arrangement allows the pulling element to be pushed together to a relatively short dimension, which in turn is necessary in order to keep the entire support element as small as possible in the minimum lifting position.
- the outer rod of the telescopic rod is guided axially in the anchoring element and can be pushed into the lower end of the supporting leg in this way. In the maximum stroke position, the extension movement of the telescopic rod is limited by appropriate stops of the rod and anchoring element.
- the support element is provided with a second limit switch and a second actuating element according to an advantageous development of the invention.
- This actuating element is also movably mounted on the support element between a first and a second position.
- the second actuating element is prestressed into the first position by means of a prestressing force.
- the second actuating element projecting axially in the direction of the anchoring element from the supporting element comes into contact with the anchoring element and is moved upward out of the supporting element when the double spindle arrangement is moved further inward. This movement out can be detected by means of the second limit switch, so that the reaching of the minimum stroke position can be indicated electrically.
- This second actuating element can also be used to actuate a third limit switch, the switching state of which indicates that the minimum retracted position, ie the roller extended position, has been reached. If the double spindle arrangement is moved further into the supporting leg after the minimum stroke position has been reached, the second actuating element moves further upward beyond the supporting element. Above the second limit switch is the third limit switch, which triggers from a certain protrusion of the second actuating element above the support element and thus indicates the minimum retracted position of the double spindle arrangement in the supporting leg. This position would also be electrically detectable. With All signals of the limit switches can be controlled by a forced shutdown of the drive motor, which improves the ease of use of the mainstay.
- the length-adjustable support element according to the invention is used for the pillars of a height-adjustable bed, it is sometimes desirable to move these beds into a Trendelenburg or anti-trend castle position.
- the drive can also be automatically switched off when the Trendelenburg or anti-trendel castle position is reached.
- a swivel element is expediently mounted near the support element about a swivel axis running transversely to the longitudinal extent of the supporting leg, the swivel element having a further actuating element for actuating either the fourth or the fifth limit switch for signaling the maximum bed inclination (Trendelenburg or anti-trending castle position).
- the two additional limit switches can be mounted in a compact arrangement and on a common holder.

- the four pillars 16 are connected to one another by longitudinal and transverse connecting struts 18, 20.
- the upper frame 12 of the bed 10 has a frame 22 which has longitudinal spars 24 and transverse struts 26 extending transversely thereto.
- the longitudinal bars 24 protrude at their ends via the connection points with the cross struts 26.
- the head and foot parts 28, 30 of the bed 10 are attached to the projecting ends of the longitudinal spars; side parts 32 of the bed can be attached to the longitudinal spars 24. These side parts 32 can also be attached to the head and foot parts 28, 30 of the bed.
- the mattress support device (not shown in FIG. 1), which comprises a plurality of motor-adjustable support elements, has corresponding configurations on its long sides.
- each support leg 16 has an inner tube 34 and an outer tube 36 arranged concentrically to it.
- the longitudinal and transverse connection beams 18, 20 are attached to the outer tubes 36 of the legs 16.
- each support leg 16 has a steering and / or roller 40 of a running surface 41, the roller 40 being held by a holding element 42 with a guide pin 44.
- This guide pin 44 is guided axially displaceably in a lower end insert plate 46, which is arranged at the lower end 48 of the inner tube 24.
- the outer tube 36 projects beyond the lower end 48 of the inner tube 34; in this area, a frustoconical or bell-shaped insert 50 is inserted into the supporting leg 16, which is open towards the lower end 38 of the supporting leg 16 and receives the roller 40 together with the holding element 42.
- the circumferential wall 51 of the insert part 50 extends at an acute angle to the outer tube 36, so that a tapering space 49 is formed between the two, into which a pipe cladding is inserted in the lowest position of the supporting leg 16, saving space and height (see FIGS. 3 to 5).
- the lower end 38 of the support leg 16 is formed by the lower end of the outer tube 36. This lower end 38 is provided with an annular standing edge 52, by means of which the standing leg 16 rests on a base 54 when the guide bolt 44 is freely movable into the lower end 48 of the inner tube 34. This situation is shown in FIGS. 2 and 3 are shown.
- the double-spindle arrangement 58 comprises an inner spindle 60 and a hollow spindle 62, which are in threaded engagement with one another.
- the hollow spindle 62 has at its one axial end (upper end) 64 an insert part 66 with an internal thread, which is in threaded engagement with the external thread of the internal spindle 60.
- the hollow spindle 62 can be moved into or out of the inner tube 34 by turning into the inner tube 34 of the supporting leg 16.
- the inner tube 64 has at its upper end 68 an insert 70 with an internal thread, which is in threaded engagement with the external thread of the hollow spindle 62.
- the lower end of the hollow spindle 62 located in the inner ear 34 is closed by a pressing body 72, which will be discussed further below.
- the latter is rotatably mounted on a support element 76.
- This support element 76 is attached to the frame 22 of the bed 10 from below, the cross strut 26 being supported on the support element 76.
- the support element 76 has the rotary bearing 78, through which the upper end 74 of the inner spindle 60 extends.
- stop rings 80 are located on both sides of the rotary bearing 78 or the support element 76, which prevent a translational relative movement of the inner spindle 60 relative to the support element 76 when the inner spindle 60 rotates.
- 16 gear wheels 82 are attached to the upper ends 74 of the inner spindles 60 of each supporting leg.
- a belt drive with a toothed belt 84 which runs along the transverse struts 26 of the bed frame 22, runs around the gearwheels 82 of the pairs of legs on the headboard part and on the footboard side.
- a drive gear 86 meshes, which is driven by an drive motor 88 is driven.
- the double spindle arrangements 58 on the head and foot part sides can be actuated in pairs synchronously by the drives 88 and separately for the legs 16 on the head and foot part side.
- a telescopic tube arrangement 90 is attached to the support element 76 assigned to a supporting leg 16.
- This tube arrangement 90 extends coaxially to the double spindle arrangement 58 and is guided in the outer tube 36 of the supporting leg 16.
- the tube arrangement 90 comprises an upper tube section 92, which can be telescoped with a central tube section 94, which in turn is guided in the outer tube 36 of the supporting leg 16 and is telescopic with the latter. While the middle pipe section 94, which is freely movable between the outer pipe 36 and the upper pipe section 92, automatically moves into the outer pipe 36, it is carried along by the upward movement of an outer collar 96 on the upper pipe section 92, which is surrounded by an inner collar 98 on the middle pipe section 94 is.
- the inner spindle 60 is moved into the hollow spindle 62.
- the hollow spindle 62 is carried along.
- the stop element 80 lies against the upper end 64 of the hollow spindle 62 when the inner spindle 60 is retracted and prevents the further rotation of the inner spindle 60 relative to the hollow spindle 62.
- the hollow spindle 62 is now moved into the inner tube 34 until the pressing body 72 comes into contact with the guide pin 44 (minimum stroke position). This situation is shown in Fig. 3.
- the double spindle arrangement 58 is driven in the opposite direction, the spindles 60, 62 move out of the supporting leg 16 again.
- the inner and outer tubes 34, 36 are first lowered (see FIG. 5) until the stand edge 52 rests on the base 54 (minimum stroke position). Only then does the double-spindle arrangement 58 move further out of the inner tube 34. In the initial phase of this movement, one of the two spin-ins moves relative to the other or relative to the inner tube 34.
- the movement of the hollow spindle 62 out of the inner tube 34 ends at the moment when the pressing body 72 on the threaded insert 70 at the upper end 68 of the inner tube 34 abuts.
- the inner spindle 60 Upon further rotation, the inner spindle 60 then unscrews from the hollow spindle 62 until this extension movement is ended in the maximum stroke position shown in FIG. 2. Should the inner spindle 60 first rotate in the hollow spindle 62 during the extension movement of the double-spindle arrangement 58, then the moment when a the radially projecting flange 100 arranged at the end of the inner spindle 60 strikes the inner thread insert part 66, the hollow spindle 62 is rotatably carried along by the inner spindle 60.
- the case is dealt with in that the pressing body 72 attached to the hollow spindle 62 acts on the guide pin 74.
- the hollow spindle 62 is open at its lower end and that the inner spindle 60 then acts on the guide pin 44.
- the drive motor 88 is automatically switched off, which is done by means of a limit switch device 102.
- This limit switch device 102 has a first limit switch 104, a second limit switch 106 and a third limit switch 108 (see FIGS. 6 to 11).
- a first and a second actuating element 110, 112 are assigned to these three limit switches 104, 106, 108, which are each designed as pushbuttons, the first actuating element 110 actuating the first limit switch 104 and the second actuating element 112 acting on the other two limit switches 106 and 108.
- the two actuating elements 110, 112 are designed as bolts which are axially displaceably mounted on the supporting element 76 in the axial extension of the supporting leg 16 and which extend over the upper side of the supporting element 76 through the cross strut 26.
- the first actuating element 110 is prestressed in a first position, in which it protrudes further over the upper side of the cross strut 26 than in its second position, into which it can be transferred under tension of a prestressing spiral pressure spring 114, which is located between a thickened end of the first Actuating element 110 and the support element 76 supports.
- the second actuating element 112 is likewise pretensioned in its first position, specifically by means of the spiral spring 115 towards the underside of the support element 76, via which it protrudes in the direction of the outer tube 36. In the- In this first position, the second actuating element 112 does not protrude above the upper side of the cross strut 26, so that it does not actuate the second limit switch 106 either.
- a pulling element 116 in the form of a telescopic pull rod 118 is connected to the first actuating element 110 and extends coaxially to the extension of the supporting leg 16 into its outer tube 36 and is arranged there between the inner tube 34 and the outer tube 36.
- This telescopic rod 118 has an inner rod 120 and an outer rod 122 (see, for example, FIGS. 8 and 9).
- the pull-out movement of the inner rod 120 from the outer rod 122 is limited and overall the entraining movement of the telescopic rod 118 when extending the supporting leg 16 is limited by the outer rod 122 being guided through a through opening in an anchoring and stop element 124 which is fixed on the outside of the inner tube 34 is appropriate.
- the interaction of the anchoring and attachment elements 124 with the telescopic rod 118 for moving the first actuating element 110 and with the second actuating element 112 is described below with reference to FIGS. 7 to 11 received.
- FIG. 7 which corresponds to the standing leg position according to FIG. 3, shows the situation in the minimum lifting position.
- the second limit switch 106 is closed by the second actuating element 112, which indicates that the minimum stroke position has been reached.
- the first limit switch 104 is also closed in the minimum stroke position by the first actuating element 110.
- this switching status is not queried. If the supporting leg 16 is extended based on the situation according to FIG. 7, the second actuating element, which was moved into the second position against the biasing force by the anchoring and stop element 124 to actuate the second switch 106, is released ( see Fig. 8), so that the second limit switch 106 changes its switching state.
- the supporting leg 16 is transferred from a lifting position that lies between the maximum lifting position and the minimum lifting position to the minimum lifting position, the situation according to FIG. 10 arises shortly before the minimum lifting position is reached, which is comparable to the supporting leg position according to FIG. 3 .
- the anchoring and stop element 124 bears against the second actuating element 112 or is arranged in the immediate vicinity thereof.
- the anchoring and stop element 124 moves the second actuating element 112 upward, so that the second limit switch 106 is actuated (see also FIG. 7). This signals that the minimum stroke position has been reached.
- the anchoring and stop element 124 moves the second actuating element 112 further up out of the support element 76 and the cross strut 26 until the one arranged above the second limit switch 106 third limit switch 108 is actuated (see FIG. 11, which corresponds to the standing leg position according to FIG. 4).
- FIG. 11 which corresponds to the standing leg position according to FIG. 4
- the lower end 38 of the supporting leg 16 is above the roller 40 moves so that the bed now rests on the roller 40 and can be moved.
- the bed 10 also has the possibility of tilting the upper frame 12 into a Trendelenburg and an Antitrendelenburg position. These two positions are also detected electrically, for which purpose a fourth and a fifth limit switch 128, 130 are provided. These two limit switches 128, 130, together with the remaining three limit switches 104, 106, 108, are attached to a common holding part 132, which in turn is attached to the top of the cross strut 26. The two limit switches 128, 130 are arranged opposite one another (see in particular FIGS. 12 and 13).
- a pivot element 134 is arranged on the cross strut 26 so as to be rotatable about a pivot axis 136, this axis of rotation 136 extending transversely to the longitudinal extension of the supporting leg 16.
- the longitudinal beam 24 of the upper frame 12 of the bed 10 is attached to the pivoting element 136.
- a further actuating element 138 protrudes from the pivoting element 134, which protrudes into the intermediate space 140 between the two limit switches 128, 130.
- one of the two limit switches 128, 130 is switched by the actuating element 138 when two relative pivoting positions of the longitudinal spars 24 relative to the supporting legs 16 are reached, so that the drive motor 88 for the respective supporting leg pair 16 can be switched off automatically.
- the integration of the limit switches signaling that the Trendelenburg and Antitrendelenburg positions have been reached is solved in a very compact manner.
