Definitions
- the invention relates to a height-adjustable bed that can be used in particular as a hospital or nursing bed.
- the bed In the case of sick beds or nursing beds, it is advantageous in terms of the care of the patient or the person in need of care (hereinafter, for the sake of simplicity, we will only speak of the patient) if the bed can be adjusted in height. It is also required that the bed can be moved easily, so that its support legs should be provided with castors or castors. When the patient is being cared for, however, the bed should inadvertently no longer be able to be moved, which is why the bed should have an appropriate braking device. In order to ensure easy and convenient handling of the bed, it is advantageous if the braking device is activated automatically as soon as the bed is raised.
- a height-adjustable bed in which four guide elements are arranged on a bed frame, from which support legs can be pushed down or into which the support legs can be moved from below.
- the support legs can be moved by means of a lifting device over the lower ends of the guide elements facing the floor.
- the bed rests on the floor above its castors.
- the guide elements lift off the ground.
- the casters are at a considerable height above the floor because the distance of the casters from the bed frame remains unchanged.
- the "lifting" of the castors affects the overall aesthetic impression of the bed.
- the invention has for its object to provide a height-adjustable bed in which the brake mechanism can be canceled in a structurally simple and user-friendly manner even in the raised state of the bed.
- the invention proposes a height-adjustable bed that can be used in particular as a hospital or nursing bed and is provided with a bed frame, which has a frame with guide elements attached to it, in which support legs are slidably guided with rollers for moving the bed frame, a lifting device for displacing the support legs and the guide elements relative to one another between a minimum extended position and a maximum extended position, at least one of the support legs is associated with a braking device which, in a locking position in which the bed frame cannot be moved, can be transferred and into a release position in which the bed frame can be moved, the braking device being controlled by the lifting device in the locking position and in the release position is transferable, in such a way that when the support leg is in the minimum extension position and the lifting device is activated, this first transfers the braking device from the release position into the locking position and then extends the support leg so that d The braking device remains in the locking position during the extension movement of the support leg until it reaches its maximum extension position or an intermediate position
- the bed according to the invention is provided with a bed frame which has a frame with guide elements attached to it, on which support legs are guided in a linearly displaceable manner and have rollers at their downward-pointing ends.
- the support legs are in hers respective displacement position can be locked relative to the guide elements.
- All support legs can be moved along the guide elements by means of a lifting device, namely between a minimum extension position in which the bed occupies its lowest height position and a maximum extension position in which the bed is raised the highest.
- At least one support leg and preferably each support leg is assigned a braking device which can be moved into a locking position and a release position. The bed cannot be moved in the locking position, while it can be moved in the release position of the braking device.
- the braking device either acts on the castors and blocks them directly or indirectly on the outer or inner radius, namely non-positively (i.e. positively and / or frictionally) in the locking position, or it acts on the surface on which the bed rests (Floor brake).
- the braking device for transferring from the release position into the locking position and vice versa is controlled by the lifting device, both in the minimum extension position of the legs and in their maximum extension position or an intermediate position between these positions shortly before the maximum -Extension position.
- the braking device is actuated by the lifting device in such a way that the lifting device, when the support legs are in the minimum extension position, first transfers the braking device from the release position to the locking position, in order to then extend the support legs.
- the brake device is in its locking position during the entire extension movement.
- the nursing staff can now move the bed to the appropriate height for patient care. In the raised state of the bed, the braking effect of the braking device is canceled by the fact that the lifting device is activated even after the maximum extended position has been reached, thereby moving the braking device from its locking position to the release position.
- the height shift of the bed and the braking device are accomplished or controlled by one and the same mechanism, namely the lifting device. Additional actuators with corresponding additional drives for it are therefore not provided in the bed according to the invention.
- the operation of the bed according to the invention is very simple, since the activation or deactivation of the braking device can ultimately be carried out by the same switch or by two different switches which are / are also operated to activate the lifting device.
- the lifting device is automatically deactivated when the bed is raised when the support legs reach their maximum extension positions. So if the nursing staff wants to move the bed into the highest position in which the bed should of course be braked, this is achieved by automatically switching off the lifting device according to this development of the invention.
- a switch is actuated, which is preferably the switch with which the lifting device has also been activated to extend the support legs.
- the actuation of the lifting device in order to transfer the braking device from the release position into the locking position with the bed lowered to a maximum also takes place via the switch with which the extension movement of the support legs is triggered.
- a further switch can be provided for this.
- the lifting device is only activated until the braking device has been transferred from the release position into the locking position (with the support legs in their minimally extended position).
- the lifting device should expediently be switched off, which must then be reactivated for the actual extension movement of the legs.
- the bed according to the invention is operated in a reliable and convenient manner both for the patient and for the nursing staff.
- the lifting device acts on the braking element via a pressing element, that as a result the braking element moves against a stop on the supporting leg in order to support the supporting leg upon further action of the lifting device on the braking element so to speak, to take along and go out.
- the braking device assumes its locking position, in which the braking element acts either on the roller or directly on the floor.
- the guide element has a driver which engages on a stop of the braking element when the support leg is in the maximum extended position.
- the support leg with the brake element located in it moves relative to the guide element into the maximum extended position. In this position, the braking element strikes the driver with a stop. If the support leg is now moved beyond this extended position, the driver retains the braking element, which thus moves into the support leg relative to it and thus moves the braking device from the locking position to the release position.
- the braking device is moved from its locking position to the release position in that the support leg is still moved a little beyond the maximum extension position or the guide element is moved relative to the support leg. This small relative movement amount is sufficient to experience the braking element so that the braking device is transferred from its locking position to the release position.
- the braking element is designed as a tappet, on one end of which the lifting device acts with its pressing element or the like, and on the other end of which a brake pad is arranged.
- the lifting device has one automatically, i.e. one pair consisting of one guide member and one supporting leg.
- motor, hydraulically or the like pivotable pivot lever one end of which is rotatably mounted on the frame and / or on a guide element of the bed frame and the other end acts on the associated support leg in order to move it along the guide element.
- the pivoting lever does not act directly on the support leg but rather indirectly via the brake element, which supports itself on the support leg.
- the guide elements and support legs are expediently arranged in pairs at the foot end and at the head end of the bed frame, two pivot levers being arranged at each end of the bed frame.
- the pivot levers are alternately rotatably mounted on opposite guide elements, while the free action ends act on the support legs of the other guide ends.
- the force for pivoting the swivel levers is preferably applied in the (geometric) center of the swivel lever.
- the swivel levers run and move in mutually parallel planes.
- the pivot levers which are supported at their ends on a guide element and a support leg of the two legs at the head end or foot end, rotate about their centers in opposite directions when the bed is changed in height.
- Each pivot lever is expediently made of a flat material (steel plate), wherein it has a greater width in its central region between the two ends than at its ends, towards which the pivot lever tapers.
- the pivot lever has a diamond-like shape.
- Such flat swivel levers can be accommodated in the head and foot ends of the bed frame, which protrude above the mattress, to save space.
- the pivoting movement of a pair of pivoting levers arranged in a foot end or head end expediently takes place by means of a spindle drive which meshes with a connecting element which is connected in an articulated and movable manner to the central sections of the pivoting levers, which is preferably carried out via handlebar levers whose one ends are rotatable with the pivoting levers and the other ends of which are rotatably connected to the connecting elements.
- the spindle of the spindle drive extends parallel to the guide elements or support legs and is rotatably mounted on the bed frame so as to be secured against axial displacement. When the spindle rotates, the swivel levers rotate about their pivot points with the bed frame or the guide elements and theirs Support points on the support legs or the at least one brake element assigned to one of the support elements.
- the pivot lever which is assigned to the support leg provided with the braking device is coupled at its end of action and is articulated to the plunger of the braking device.
- This plunger is expediently mounted displaceably in the support leg between a disengagement position and a withdrawal position, it running parallel to the extension of the support leg.
- the above-mentioned articulated and slidable connection of the action end of the pivot lever with the plunger is expedient in order to convert the pivoting movement of the pivot lever into a linear movement of the supporting leg while maintaining its coupling with the plunger of the braking device.
- the plunger has an elongated hole extending in its direction of movement, in which one end of a connecting lever is guided, the other end of which is articulated to the end of the pivoting lever.
- the acting end of the pivoting lever is provided with an elongated hole which extends essentially transversely to the pivoting direction of the pivoting lever and in which the plunger is guided. Both alternatives are useful in that the pivoting movement of the pivoting lever can be converted into a linear movement of the support leg while maintaining the coupling with and the pressure against the plunger.
- the bed is provided with a bed frame that has a frame with guide elements attached to it, in which support legs are slidably guided with rollers for moving the bed frame, a lifting device for displacing the support legs and the guide elements relative to one another between a minimum extension position and a maximum -Extension position, with at least one of the support legs being assigned a braking device which can be transferred in a fixing position in which the bed frame cannot be moved and in a release position in which the bed frame can be moved, the braking device having a braking element, that can be moved by the lifting device with the support leg located in the minimum extension position for transferring the brake device from the release position into the locking position, the braking element being in the locking position in the locking device on the support leg and / or an on Impact of the support leg rests and a pressing element of the lifting device, which can be driven by a drive device of the lifting device supported on the frame, presses against the braking element and moves the supporting leg and the guide element relative to one another via this.
- the braking element is a pressing element that is against the bed frame supporting lifting device is driven, moved against the support leg and brought into contact with it.
- the pressing element then moves the support leg and its guide element apart from one another via the braking element.
- the braking device is controlled by the lifting device and transferred from the release position into the locking position before there is a relative movement of the support leg and guide element.
- the roller of the support leg remains in the area near the ground, ie immediately above the floor on which the bed rests. The relative position of the roller to the ground when the braking device is in the locking position thus remains the same when the height of the bed frame is changed.
- the bed according to this third variant of the invention is provided with a bed frame which has a frame with guide elements attached to it, in which support legs are slidably guided with rollers for moving the bed frame, and a lifting device for displacing the support legs and the guide elements relative to one another between a minimum -Extension position and a maximum -extension position, wherein the lifting device for each pair consisting of a guide element and a support leg has an automatically pivotable pivot lever, one end of which is rotatably mounted on the frame and / or a guide element of the bed frame and the other end acts on a support leg.
- the support legs of two adjacent legs of the bed are alternately connected via two pivot levers.
- Each pivot lever is supported on the guide element of one leg or the frame of the bed frame and on the support leg of the other leg of the bed frame.
- the lifting device described here and the height-adjustable bed with this can advantageously be combined with the various developments of the braking device described above.

- the two electric motors 46 are electrically connected to a control unit 48, to which an operating unit 50 with a plurality of operating buttons 52, 54, 56 is also connected.
- Each leg 36-40 of the bed 10 is provided with a braking device 58 which is disposed within the support legs 30-34. The braking device 58 located in the support leg 32 is explained in more detail below with reference to FIG. 2.
- the brake device 58 has a brake element 60 designed as a tappet, which extends parallel to the support leg 22 through the latter.
- the braking element 60 also extends through the roller holder 42 mounted on the support leg 32, the lower end of the braking element 60 being located between the roller holder 42 and the base 64 on which the bed 10 rests.
- This end 62 is provided with a rubber brake pad 66.
- the braking element 60 extends through a passage 72 which is firmly connected to the support leg 32.
- a radially protruding support ring 74 is fastened to the brake element 60 below the feedthrough 72, on which a prestressing helical compression spring 76 is supported with one end, the other end of this spring 76 abutting the feedthrough 72.
- a stop element 78 is fastened to the brake element 60, which is arranged within the support leg 32 above the roller holder 42. This stop element 78 is located near the closed lower end 80 of the support leg 32, through which the braking element 60 extends.
- the end 68 of the braking element which projects upward above the leadthrough 72 is widened and has shoulder stops 82 which can be brought into contact with the leadthrough 72.
- a driver rod 86 is attached, which protrudes from above into the support leg 32 and extends into it.
- the driver rod 86 has a stop 88 at its free end, which with an extension 90 at the upper end 68 of the braking element 60 cooperates in a manner to be described.
- the motors 46 are part of a lifting device 92 which is accommodated in the head end 26 and in the foot end 28 of the bed frame 12.
- the lifting device 92 is of identical design in both ends 26, 28 of the bed frame 12; the structure of the lifting device at the foot end 28 is explained in more detail below with reference to FIG. 2.
- the lifting device 92 has a spindle 94, which is rotatably mounted on the cross member 18 of the bed frame 14 and on an upper end 84 of the guide elements 22, 24, each connecting strut 96 and secured against axial displacement.
- the motor 46 is flanged to the cross member 18 and drives the spindle 94.
- the spindle 94 is in threaded engagement with a connecting element 98, on which two handlebar levers 100 are articulated. These handlebar levers 100 are connected at their ends facing away from the connecting element 98 with diamond-shaped pivot levers 102, 104.
- the pivot lever 102 is rotatably mounted about a pivot axis 106 of a fitting 107 arranged on the guide element 24 parallel to the longitudinal and transverse bars 16, 18, while the other pivot lever 104 is pivotable about a pivot axis 108 of a fitting 109 arranged on the guide element 22 parallel to the pivot axis 106 is stored.
- the free ends 110, 112 of the pivot levers 102, 104 respectively opposite the pivot axes 106, 108 are connected to the broadened upper ends 68 of the brake elements 60 via connecting levers 114.
- connecting levers 114 are connected in an articulated manner to the free ends 110, 112 of the pivoting levers 102, 104 and are guided at their other ends in elongated holes 116 which are formed in the widened upper ends 68 of the braking elements 60 and which extend in the longitudinal direction of the braking elements 60. fen.
- the lever 114 is connected to a bolt 117 which extends through the elongated hole 116.
- the spindle 94 is driven in rotation by the motor 46, as a result of which the connecting element 98 is moved in the direction of the arrow 118 towards the cross member 18.
- the connecting element 98 takes the pivot levers 102, 104 with them via the handlebar levers 100, so that they pivot about their axes of rotation 106, 108 in the direction of the arrows 120.
- the fittings 107 and 109 for the axes of rotation 106, 108 move are linear in the direction of the arrows 121.
- the free ends of the pivoting levers 110, 112 act on the brake elements 60 which, because supported by the stop elements 78 and the shoulder stops 82 on the support legs 32, 34, lead to an extension movement of the support legs 32, 34 or an upward movement of the guide elements.
- the individual phases of the pivoting movements of the pivoting levers 102, 104, the actuation of the braking devices 58 and the linear movements of the support legs 30, 34 and guide elements 22, 24 are shown in FIG. 2 with arrows 120, 121 drawn in solid lines for the case of starting up and with arrows 120, 121 drawn in dashed lines in the event of the bed being shut down and are subsequently explained using FIGS. 2-7 explained in more detail.
- FIG. 2 shows the situation in which the brake device 58 is in its release position, in which the brake elements 60 have been drawn into the support legs 32, 34 so far that the rubber blocks 66 are arranged above the base 64.
- the release position the braking elements 60 are namely against the force of the pretensioning springs 76 are drawn into the support legs 32, 34 and held there.
- the pivot levers 102, 104 which assume their uppermost pivot positions and pull the brake elements 60 up against the force of the springs 76 via the connecting levers 114. If the motor 46 is activated in this situation, the pivot levers 102, 104 pivot in the direction of the arrows 120.
- the braking elements 60 can move in the direction of the ground 64 due to the force of the springs 76 until the rubber brake pads 66 rest. This position is shown in Fig. 4. In this situation, the stop element 78 of the braking element 60 and the shoulder stops 82 are still slightly spaced from the lower, closed end 80 of the support leg 32 or from its passage 72. The braking device 58 is now in its locking position, in which it secures the bed 10 in the lowered state against movement.
- the connecting lever 114 is first shifted within the elongated hole 116 until it abuts the lower boundary of the hole 116. From now on, the pivot lever 102 presses against the brake element 60 via the connecting lever 114 and against the base 64 via this.
- the brake element 60 is supported on the bushing 72 via its shoulder stops 82 and on the lower end 80 of the support leg 32 via its stop element 78. The result of this is that the pivot lever 102 is now pivoted about its free end 110 and is thus raised at its opposite end, which is rotatably connected to the opposite guide element 24, taking the guide element 24 with it and lifting it up.
- the swivel lever 104 which is supported with its free end 110 on the brake element 60 in the support leg 34, has the same effect on the guide element 22, so that this is raised relative to the support leg 32. As a result, the support legs 32, 34 extend out of the guide elements 22, 24 (see FIG. 5).
- the braking devices 58 remain in their locking positions, since the braking elements 60 with their rubber brake pads 66 continue to rest on the ground 64 and raise the rollers 44 slightly.
- pivot lever 102 has elongated holes 124 which extend approximately transversely to the pivoting movement of the free ends 110 of the pivot levers.
- a bolt 126 is movably guided in each of these elongated holes 124 and also extends through the elongated hole 116 of the brake element 60 to which the relevant pivot lever 102, 104 is coupled.
- the situation is depicted in which the actors 110 of the pivot levers 102, 104 act on the support legs 30-34 via the brake elements 60 (at 82 and 78) in order to move the support legs 30-34 and the guide elements 20-24 apart cause.
- the acting ends 110 of the swivel levers 102, 104 lie directly on the support legs 30-34 (for example at 128) in order to realize the movement apart.
- the braking elements 60 are brought into contact with the support legs 30-34 by 110 of the swivel levers 102, 104 by the force of the springs 76 into the locking position from which they can be moved against the force of the spring 76 into the release position via the driving rod 86 if the guide elements 20-24 and the support legs have moved apart far enough (maximum extension position).
- the (connecting) bolts 117 between the connecting levers 114 and the upper end 68 of the braking elements 60 are thus in the maximum extension position when the support legs 30-34 are pivoted.
- the pivot levers 102, 104 hold the brake elements 60 against the force of the spring 76 in the raised position spaced from the ground 64 via the connecting lever 114.
- they release the braking elements 60 so that they rest on the ground 64 (locking position of the braking device).
- the actuators 110 of the swivel levers 102, 104 come into contact with the support legs 30-34 (which can be done, for example, at 128).
- the bed 10 is fixed in that the brake pads 66 of the brake elements 60 rest on the base 64.
- a determination of the bed 10 can, however, also be achieved in that the brake elements 60 press against the running surfaces of the rollers 44 and additionally lock the rotary bearings of the roller holders 42 on the support legs 30-34.
- a possible construction for such a braking mechanism is shown in FIGS. 9 and 10, the parts of this braking mechanism which correspond to the parts of the braking devices 58 of FIGS. 1 to 7 correspond, are identified by the same reference numerals.
- the switches 52 of the control unit 50 are used, for example, to bring the multi-part slatted frame of the bed 10 into a wide variety of positions.
- the switches or pushbuttons 54, 56 serve for the upward and downward movement of the bed 10. For the following considerations, it is assumed that the bed 10 is in its lowest position and that the braking devices 56 are in their release positions. If, for example, the bed is now to be moved, the button 54, which must also be pressed to move the bed 10 upwards, is actuated. As a result, the drive motors 46 are activated so that the pivot levers 102, 104 pivot in the direction of the arrows 120.
- 3 and 6 can be recognized, for example, by a switch which responds when the stop 88 of the driving rod 86 abuts the extension 90 of the braking element 60.
- the bed is automatically moved to its highest position, in which it is still braked by the braking devices.
- the pivot levers 102, 104 are then pivoted further in the direction of the arrows 120 in order to transfer the braking devices into the release positions.
- the bed can be transferred from the raised, non-braked position to the lowered, non-braked position, with the drive motors 46 being forcibly switched off when the braking devices are in their locked positions in the raised position are transferred and the bed is lowered into the lowest position when the braking devices are in the locking positions.
