Definitions
- the invention relates to a bed frame for a hospital bed and/or care bed, with a scissor mechanism for adjusting the height of a bed frame supported by the scissor mechanism, and with a first and a second running gear, each arranged on the scissor mechanism, with a running gear having a traverse with bearing bushes at the ends for receiving a respective Having a wheel unit with a wheel disc mounted so as to be rotatable about an axis of rotation.
- the bed frame serves to support a bed frame.
- the bed frame in turn serves to accommodate a mattress base, for example a slatted frame, or is designed as such.
- hospital beds and/or care beds usually also have a height adjustment device that supports the bed frame and is used to move the height of the bed frame together with the mattress pad and adjust it as needed.
- a height adjustment device can be designed as a hydraulically or pneumatically operated lifting device or as a scissor mechanism.
- a lifting device typically has two lifting cylinders, one lifting cylinder being provided for each bed headboard, which is provided on the main outside of the respective bed headboard.
- a particular advantage of such a lifting device is that the bed can be moved far down to a comparatively low entry height. This is possible because the lifting cylinders are not installed underneath the bed frame, but on the outside of the headboards and do not prevent the bed frame from moving downwards.
- attaching the lifting cylinders to the outside of the headboards is also a disadvantage. Because a bed equipped with lifting cylinders builds up accordingly in the longitudinal direction of the bed, which makes maneuvering more difficult in the event of a repositioning of the bed and accommodation in terms of its size can make standardized deposits impossible.
- In particular, in the health and / or care sector are transport facilities such. Elevators, but also doors, corridors and/or the like, are standardized in terms of their size and usually only allow difficult use of beds equipped with a lifting device, which do not meet this standard.
- the scissor mechanism is used as the height adjustment device. This is arranged below the bed frame, so that a bed equipped with it does not build up in the longitudinal direction, which means that it is easily manoeuvrable and, in particular, compatible with the size dimensions that are typical in the hospital and/or nursing sector.
- a chassis is provided for each headboard.
- the bed frame has a first, head-side and a second, foot-side running gear, which are arranged on the scissor mechanism and carry it in a movable manner.
- the chassis are connected to each other by means of longitudinal struts, which provides the necessary stability when the scissor mechanism is used as intended.
- Each running gear has a traverse running in the transverse direction of the bed with bearing bushes at the ends, which are used to accommodate a wheel unit.
- each wheel unit has a wheel disc which is mounted such that it can rotate about an axis of rotation.
- the size of the outside diameter of such a wheel disc has a not inconsiderable influence on the step-in height that can be reached when the scissor mechanism is lowered, because the smaller the outside diameter of a wheel disc, the lower the step-in height.
- comparatively small wheel discs do not allow the accommodation of a parking brake, which is desirable to be easy to operate. There are therefore conflicting interests with regard to the size of the wheel discs to be used. And so a bed with a generic bed frame typically has an entry height of 250 mm, for example.
- the object of the invention is to further develop a bed frame of this type in such a way that a comparatively low step-in height of less than 250 mm is achieved, while at the same time maintaining or even improving walking comfort when using a bed frame as intended Bed frame equipped bed.
- the invention proposes a bed frame of the type mentioned at the beginning, which is characterized in that a chassis has a connecting extension pointing downwards, starting from the traverse, which is arranged on one end on the traverse and on the other end a bearing eye for the pivotable arrangement on the scissor mechanism, wherein the axis of rotation defined by the bearing eye runs below the axis of rotation of a wheel disc in the vertical direction of the chassis.
- a traverse is provided on which both the wheel units and the scissor mechanism are arranged.
- the bed frame according to the invention has a chassis in which only the wheel units are arranged on the traverse.
- a connecting extension is provided for the scissors mechanism.
- the scissor mechanism is not arranged directly on the traverse, but rather indirectly with the intermediate arrangement of the connecting extension on the traverse.
- the connecting extension is aligned pointing downwards, starting from the traverse.
- connection extension is equipped with a bearing eye for the pivotable arrangement of the chassis on the scissor mechanism. This takes in the final assembly State on a corresponding coupling element for the arrangement of the scissors mechanism which can be rotated.
- the axis of rotation defined by the bearing eye runs below the axis of rotation of a wheel disc in the vertical direction of the chassis.
- the connection point of the scissor mechanism is thus offset downwards in comparison to the prior art, specifically below the axis of rotation of a wheel disc of a wheel unit.
- connection point of the scissor mechanism to the respective chassis is offset downwards in the height direction of the driving values.
- this lowering of the scissor mechanism does not come at the cost of smaller wheel discs and the associated disadvantages.
- a constructive solution is provided in that a connecting extension is used, which is arranged on one end on the traverse and which on the other end provides a bearing eye for connecting the scissor mechanism.
- the connecting extension starting from the traverse, points downwards in the height direction of the chassis, as a result of which the low positioning of the scissor mechanism in relation to the chassis is achieved in comparison to the prior art.
- a bed frame is proposed for the first time that does not have a lifting device, but rather a scissor mechanism for adjusting the height of the bed frame, but which can nevertheless be moved down to a very low entry height of 100 mm, for example, and this with the simultaneous use of comparatively large wheel discs, which ensures smooth running and good running comfort when used as intended.
- a chassis two Has connection extensions, wherein the axes of rotation defined by the bearing eyes of the connection extensions are aligned.
- connection extension not only one connection extension is used to connect the scissor mechanism to a chassis, but rather two connection extensions. There is thus increased stability of the overall construction. In addition, any tilting moment is counteracted, since the scissor mechanism is mounted on two points for each chassis.
- the rotary pivotable arrangement of the scissor mechanism on a chassis is necessary in order to be able to bring about a length compensation in the longitudinal direction of the bed when the height adjustment is used as intended.
- the scissor mechanism rotates relative to the chassis about the axes of rotation provided by the bearing eyes. So that this is possible without tilting, the axes of rotation provided or defined by the bearing eyes are aligned with one another.
- the connecting extensions are each formed eccentrically in the region of an end section of the traverse. The distance between the connecting extensions in the longitudinal direction of the traverse is therefore maximized, which is advantageous for the stability and the application of force to a chassis in the event of a load. As a result, a long service life is guaranteed.
- the traverse and the connecting extensions are made of steel and are welded to one another. There is thus a cohesive and therefore particularly robust overall construction. This is also advantageous for a long service life and an overall stable overall construction.
- the scissor mechanism is offset downwards compared to a traverse of a carriage, receiving spaces are provided on the bed frame side to maximize the travel path, into which the traverses of the carriages can immerse when the scissors mechanism is lowered.
- These receiving spaces enable a maximum displacement path, since immersing the traverses into these receiving spaces prevents driving onto other bed components, such as in particular the scissor mechanism itself or the bed frame.
- the scissor mechanism In the retracted state of the scissor mechanism, it is folded up to the maximum and lies between the traverses of the running gear, which in turn are immersed with their traverses in the receiving spaces provided for this purpose. This results in an optimized, compact structure, which also contributes to being able to achieve the lowest possible entry height.
- the traverses of the two running gears are free of a common longitudinal brace.
- the running gears used according to the state of the art have longitudinal bracing.
- the traverses of the two running gears are positively coupled to one another by means of this longitudinal brace, which serves to ensure a stable design.
- the disadvantage of this design is that downward movement of the scissor mechanism is limited, resulting in a comparatively high entry height. This is because the longitudinal brace connecting the traverses to one another limits downward movement of the scissor mechanism and/or the bed frame.
- the configuration according to the invention provides a remedy here, since the traverses are free of a common longitudinal brace.
- such a floating bearing construction can be completely dispensed with, since the running gears are not coupled to one another via a common longitudinal brace, so that length compensation between the running gears can take place simply by changing the distance between the running gears, which in is simply permitted by the fact that each chassis is designed to be movable due to its wheel units.
- the length or distance compensation between the bogies required when the scissor mechanism moves is thus made possible according to the construction according to the invention without additional components simply by allowing a relative movement of the two bogies in the longitudinal direction of the bogie.
- first bearing bush accommodates a first wheel unit and the second bearing bush accommodates a second wheel unit. Wheel gondolas or double wheel units are therefore not provided. This advantageously simplifies the overall construction.
- a wheel unit therefore has two wheel discs that can be rotated about a common axis. The use of two wheel discs per wheel unit improves stability.
- the traverses of the two running gears are free of a common longitudinal brace in the manner described above, in order to be able to realize the lowest possible entry height.
- only two wheel units are preferably provided for each chassis for an overall simplified construction. The combination of these features results in a certain instability for each chassis, especially when under load.
- the running gears are each arranged in a rotationally pivotable manner on the scissor mechanism for the purpose of distance compensation, the running gears can swivel and fold in relation to the scissor mechanism in the event of a load. According to the prior art, such a pivoting is not possible because either the trusses are coupled to each other via a longitudinal brace or because double wheel units or Gondola wheels are used.
- a running gear provides a support device arranged on the traverse, with the support device having a support body that supports the traverse relative to the ground, which in Transverse direction of the traverse is spaced from the traverse.
- the support device provided according to this preferred embodiment serves to keep the chassis stable and firm even under load.
- the support device therefore ensures that the chassis cannot pivot unintentionally relative to the scissor mechanism despite the lack of longitudinal bracing and only two wheel units provided. This is because the support device counteracts a tilting moment acting on the chassis, in particular in the event of a load, which provides the necessary stability.
- the configuration of a support device according to the invention is much less expensive and complicated in construction and, moreover, does not conflict with the intentionally low entry height, which is a disadvantage of previously known constructions. In this respect, this configuration according to the invention proves to be advantageous in two respects.
- the support device has a support body. When used as intended, this rests on the subsoil at the installation site and can thus bring about the above-described support of the traverse relative to the subsoil.
- the supporting body is arranged at a distance from the cross-member in the transverse direction of the cross-member, so that tilting moments to be expected in the intended use can be reliably intercepted.
- connection extension In combination with the connection extension according to the invention, the synergetic effect of a stable and stable construction is achieved while at the same time ensuring a low entry height.
- the support device has a support strut which is arranged at one end on the traverse and which the other end carries the supporting body.
- the support strut serves to arrange the support body at a distance from the traverse. It therefore extends in the transverse direction of the traverse, being arranged on the traverse at one end and carrying the supporting body at the other end.
- the supporting body is a wheel which can be rotated about a vertical axis and has a wheel disk which can be rotated about an axis of rotation.
- the design of the support body as a wheel has the advantage that the intended movement of the bed frame is not impeded. It is also preferred to design the support body as a steerable wheel, so that any maneuvering of the bed frame is not impeded.
- a support strut is arranged centrally between the two bearing bushes of a traverse. This central design occurs in particular for reasons of improved stability.
- the end sections of the support struts of the first and second running gear, which carry the respective support body face one another.
- the support struts together with the support body therefore do not protrude below the bed frame, but are aligned in the direction of the center of the bed frame. This avoids unnecessary tripping hazards, creates a visually appealing impression and also gives a compact design.
- a wheel disk of a wheel unit of a running gear has an outer diameter of 100 mm.
- the use of comparatively large wheel discs with an outside diameter of 100 mm is made possible. This provides increased smoothness and improved
- the invention also proposes a running gear as such with the features explained above, as well as a hospital bed and/or care bed with a bed frame according to the invention.

- FIGS. 7 to 11 Figures 1 to 6 can be in different views, a first chassis 1 one recognize bed frame 3 according to the invention.
- the bed frame 3 itself is shown in FIGS. 7 to 11 in different views.
- the bed frame 3 is such in particular for a hospital bed and/or care bed.
- the bed frame 3 has a height adjustment mechanism in the form of a scissor mechanism 4 for height adjustment of a bed frame 5 carried by the scissor mechanism 4.
- the bed frame 5 is designed as a slatted frame 35 and has a plurality of slats 36.
- the slatted frame 35 is divided into different segments, namely a head segment 37, a middle segment 38, a leg segment 39 and a foot segment 40.
- the head segment 37, the leg segment 39 and the foot segment 40 are each pivotable, which allows an adjustment of the Slatted frame 35 allows to set different lying positions.
- the bed frame 3 also has a first chassis 1 and a second chassis 2, whereby the first chassis 1 is provided on the head side and the second chassis 2 is provided on the foot side.
- the chassis 1 and 2 are each arranged on the scissor mechanism 4 and, when used as intended, carry the bed frame 3 in a movable manner.
- the running gear 1 has a cross member 7 with bearing bushes 8 and 9 at the ends for receiving a wheel unit 10 and 11 respectively.
- Each wheel unit 10 or 11 in turn has wheel disks 12 and 13 or 14 and 15 which are mounted such that they can rotate about an axis of rotation 16 or 17, respectively. Due to their storage in the bearing bushes 8 and 9, the wheel units 10 and 11 can also be rotated about their vertical axis, which means that the chassis 1 and thus the bed frame 3 carried by it can be steered. This is illustrated in the drawings by the different orientation of the wheel units 10 and 11 .
- the wheel units of the foot-side running gear 2 which is not specifically shown in the figures, are designed as so-called fixed rollers, ie as non-steerable wheel units. Alternatively, these wheel units can also be designed to be rotatable about their vertical axis and be blocked in this rotational movement by means of a parking brake, which gives quasi-fixed castors.
- the chassis 1 starting from the traverse 7 there are two connection extensions 18 and 19 pointing downwards.
- the connection extensions 18 and 19 are each arranged at one end on the cross member 7 and each have a bearing eye 20 or 21 at the other end.
- the bearing eyes 20 and 21 are used for a rotationally pivotable arrangement of the chassis 1 on the scissor mechanism 4.
- the scissor mechanism 4 has corresponding receptacles for this purpose, so that in the final assembled state, for example, a bolt is positioned in a secured position on the one hand in a bearing eye and on the other hand in the associated receptacle of the scissor mechanism 4 is.
- the result is a rotationally pivotable arrangement of the chassis 1 in relation to the scissor mechanism 4, with the bearing eyes 20 and 21 defining aligned axes of rotation 22 and 23.
- the bearing eye design has the advantage that it is inexpensive to manufacture, easy to assemble and disassemble and is also stable. 1, the aligned axes of rotation 22 and 23 of the bearing eyes 20 and 21 are arranged in the vertical direction 6 below the axes of rotation 16 and 17 of the wheel disks 12 and 13 or 14 and 15 of the wheel units 10 or 11.
- the running gear 1 also has a braking device 30.
- This in turn has a pivotable lever 31 arranged on the traverse 7, which runs parallel to the traverse 7 with the interposition of two bearing levers 34 at a distance .
- End pieces 32 are provided at each end of the lever 31 and are formed, for example, from a plastic material or are plastic-coated.
- the brake device 30 can be foot-operated by means of the lever 31, with the brake device 30 acting on both wheel units 10 and 11 when in use, which enables central and at the same time safe braking.
- the particular advantage of this configuration is that it is easy to assemble or disassemble, because it enables both wheel units 10 and 11 to be operated at the same time.
- the chassis 1 also has a support device 24, as can also be seen by looking at FIGS. 1 to 6 together.
- the support device 24 in turn has a support body in the form of a wheel 26 which is arranged at a distance from the traverse 7 in the transverse direction 43 with the interposition of a support strut 25 .
- the chassis 1 therefore has a total of three wheels, namely the wheel units 10 and 11 on the one hand and the wheel 26 of the support device 24 serving as a support body. A three-point support for the chassis 1 is thus realized.
- the support strut 25 is fastened to the traverse 7 with the interposition of a connection element 29 , so that the support strut 25 does not limit the scissor mechanism 4 downwards during a displacement movement in the vertical direction 6 .
- connection extensions 18 and 19 pointing downwards in the vertical direction 6 mean that the scissor mechanism 4 is offset further downwards in relation to the traverse 7 of the running gears 1 and 2 . Because the connection extensions 18 and 19 ensure that the axes of rotation 22 and 23 of the bearing eyes 20 and 21 provided for connection to the scissor mechanism 4 are in the vertical direction 6 below the axes of rotation 16 and 17 of the wheel discs 12 and 13 or 14 and 15. In contrast to the prior art, this enables the scissor mechanism to be lowered, with the result that a lower entry height is achieved.
- the associated support device is provided for each chassis. In the event of a load, this ensures that any tilting moments that may occur can be absorbed. Despite the lack of longitudinal bracing, this results in a safe and stable stand.
- the lack of longitudinal bracing, i.e. the forced coupling of the two running gears 1 and 2, provides a further advantage.
- this is achieved in a simple manner in that the two running gears 1 and 2 can be moved relative to one another in the absence of a forced coupling.
- the other chassis is then positioned at a variable distance relative to the fixed chassis, so that the length compensation required when the scissor mechanism 4 is operated can take place as a result of its movement.
- the support body provided as the third wheel 26 also has the advantage that the running gear 1 or 2 only needs two wheel units. Neither wheel gondolas nor double wheel units are required on each side of the chassis. Because the three-point support ensures that the respective chassis is stable.
- the configuration according to the invention provides a lower entry height of, for example, 150 mm instead of the 250 mm that is otherwise usual in connection with a scissor mechanism.
- the construction according to the invention makes it possible to use comparatively large wheel disks 12 and 13 or 14 and 15 of, for example, 100 mm, so that in addition to the low step-in height, smooth running and good running comfort are ensured when moving.
