Adjustable base structure of the bed Justerbar fotkonstruktion för säng
1. Purpose of the method, device or product according to the invention: The adjustable pedestal structure supporting the bed reclining structure of the invention enables all known adjustments of the height position and tilt positions of the reclining beds reclining structure. The adjustable pedestal structure of the bed of the invention makes it possible to implement adjustable bed solutions with complete adjustment properties and representing a new generation of beds for institutional and home care, to facilitate the work of nursing staff and assistants, and to promote the rehabilitation and mental well-being of patients and the disabled. The adjustable pedestal structure of the bed of the invention can be connected to the reclining structure of almost any conventional fixed or adjustable bed solution to replace the traditional reclining support and adjustment mechanisms used therein.
2. Previously used solutions: Adjustable beds are used in hospital bed and care wards, nursing homes, nursing homes, rehabilitation facilities and homes. The control features of the beds range from simple, e.g. basic home care bed adjustments, to functionally more demanding hospital intensive care bed control movements and their other advanced intelligent features. The adjustment mechanisms of the adjustable beds can be divided into two functional groups: Group 1: Adjustment mechanisms connected to the sleeping frame structure, which are used to adjust the tilt positions of the back, hips, knees and feet of the bed base. The adjustments are made either - mechanically or electrically. The bed-level structure supporting the adjustment mechanisms is supported by either a fixed base or legs or a height-adjustable base structure. See Figure Fig.24. Group 2: The bed reclining structure> and the above-described group 1 adjustment mechanisms connected to it are supported by the height adjustment and tilt mechanisms of the 7 bed reclining structure. By combining the functions of the groups of adjustment mechanisms mentioned above, the different care and living positions of the adjustable beds - lying positions with the bed lying down - are the main side tilted down or upwards, as well as different sitting positions and the bed Lo n. standing position. The traditional support and adjustment mechanisms of the adjustable beds in the sleeping structure 2 allow the following lying level adjustment movements: Bed N 35 - adjustment of the height position of the level structure from the living height to the treatment height (Fig.15b and Fig.16), longitudinal tilting of the sleeping structure The Trendelenburg and anti-Trendelenburg positions (Fig.16 and Fig.17) and the lateral direction of the
tilt. Other known traditional control solutions are represented by the so-called standing bed (Fig.25). Conventional adjustable bed reclining mechanisms are operated by scissor mechanisms supporting the reclining structure placed under the reclining bed and resting on a wheeled pedestal structure and the spindle motors (Fig.22 and Fig.23) attached thereto, or by lifting height adjustment mechanisms of the reclining bed (Fig.2).
3. Disadvantages of previous solutions: Traditional beds are divided into types and models according to their different uses and suitable for different user groups, on which their manufacture and sale are also based. It is difficult to change the ergonomic features of traditional bed solutions for different target groups to meet the changing functional needs of the future. How to change, for example, a basic bed used in a home care or nursing home to be more versatile in its adjustments as the bed user's mobility is impaired over time. Traditional bed adjustment mechanism solutions - do not include the possibility to update the bed adjustment functions. In practice, the option is to buy a new bed. In control mechanism solutions based on the use of scissor mechanisms or lifting cylinders for conventional adjustable beds, the adjustment of the height position and tilt angle of the reclining structure - Trendelenburg and counter-Trendelenburg positions - is limited by the structural and lifting cylinders of their scissor mechanisms. The structural limitations of the adjustments are reflected in the functional characteristics of the beds themselves. Larger and more flexible trajectories than the traditional possibilities of the adjustment mechanisms of the horizontal structures would be an advantage e.g. in the demanding nursing work of hospitals. As with the invention, the traditional support and adjustment mechanisms of the sleeping platform structure do not allow for a universal bed solution with all known bed adjustment movements. For example, the so-called > Integrating the bunk bed function into a bed structure otherwise equipped with versatile control functions, such as advanced hospital beds, is not possible within the framework of traditional control mechanism solutions. However, in the care and bed wards of hospitals P and various care and rehabilitation institutions, as well as in homes, the N 30 cot function would be a very necessary feature of the bed structure to facilitate the work of nursing staff and assistants, as well as the self-sufficiency of bed users. The protection of the shackle mechanism structures below the sleeping levels of traditional bed solutions is difficult to implement. For example, homes may have 2 small children who are inadvertently ignored by the bed user when adjusting the bed independently.
4. Functional and structural features of the solution according to the invention The features of the invention are set out in claim 1. The basic idea of the adjustable pedestal structure of the bed: The adjustable pedestal structure of the bed of the invention consists of a wheeled U-shaped leg structure (30) and three leg supports. of which the lower (1a) and middle (1b) circumferential components are formed by rotating cylinders (2, 4) and lever arms (3, 7) fixedly connected thereto, and shafts (13b, 13c) fixedly connected to opposite ends of the rotating cylinders of the lever arms; and the U-shaped upper component (1c) consists of a rotating cylinder (6) and lever arms (5a) fixedly connected thereto. A fixed shaft (13a) is connected to the foot structure, which is located inside the rotating cylinder (2) of the lowest structural part (1a) of the foot structure. The bed frame structure (31) of the bed is connected to the lever arms (5a) of the uppermost component (1c). The components of the adjustable base structure are connected to each other by means of coupling and rotation mechanisms of the components formed by the rotating cylinder structures and the axle structures located inside them. The rotating cylinders act as electrically operated control mechanisms for the control movements of the components. The frame structure of the bed is adjusted in height by the adjusting movements of the lower and middle - rotating cylinders (2, 4) of the base structure (1a, 1c) and the lever arms (3, 7) connected thereto. And the longitudinal tilting position of the bed by means of adjusting movements of the connected lever arms (5a). The adjusting movement of the rotary cylinders is assisted by gas springs (26, 27, 28) connected to the lever arms of the components of the adjustable base structure, which significantly reduce the load on the components of the base structure and its electrical movement mechanisms. The circumferentially shaped lower and upper structural part (1a, 1b) of the base structure (30) and the interconnected shape (1a, 1b) and the connecting plates and cover plates (8, 9) connected to their lever arms (3, 7) stiffen the base structure laterally. The width of the adjustable base N 30 - the leg structure of the leg structure (30) of the bed is larger than the frame structure of the bed and the U-shaped structure open from the foot of the bed enables the bed. standing position function.

See also Figure Fig.1b.
The rotating cylinders (2, 4, 6) of the components of the adjustable base structure and the associated lever arms (3, 7, 5a) and the shafts (13b, 13c) connected to the lower (1a) and middle (1b) components of the base structure form a single structure, which are adjusted in the elevational order of the standing position of the bed reclining structure of the bed located inside the rotating cylinder of each component about the axis connected to the end of the lever arms of the component lower than that component or to the leg structure.
See Figure Fig.11a.
The connecting and rotating mechanism between the rotating cylinder (2, 4, 6) of each component of the adjustable base structure and the fixed shaft (13a, 13b, 13c) formed therein is formed by groove gears (21b) arranged in the mounting flanges (18, 21a) of the shaft ends. and internal circular conductors (19, 20) connected to the ends of the rotating cylinder and connected to the frame structures (22, 24) of the N lever arms. © The operation of the adjusting movements of the rotating cylinders of the adjustable pedestal structure of the bed of the invention is based on the conversion of the adjusting movement of the linear spindle motors I acting as their adjusting motors into a rotating movement by adjusting the lever arms (3, 7, 5) of the base structure 31) in different adjustment positions.
A wide spiral flange (12a) or> 35 - narrow spiral flanges (12b, 12c) are attached to the inner surface of the rotor s-tube (11) of the adjustable stand structure. A linear spindle motor acting as a rotary cylinder adjusting motor is supported on a mounting flange (18a, 21a) of the fixed shaft (13a, 13b, 13c). The spindle of the linear spindle motor pushes and pulls the thrust wheels attached to the connecting module (14a) of the motor spindle (150) and the spindle guide bearings (16) to the connecting module (14a) longitudinally, so that their forward-to-reverse force on the helical flange
The structural solution of the rotating cylinders is shown in Figures 5, 6 and 6. Connection of the components of the pedestal structure (1a, 1b, 1c) to each other and to the foot structure (30) of the pedestal structure and to the frame structure of the bed lying down
(31) is shown in connection with Fig. 10a.
The rotary cylinders of the adjustable pedestal structure of the bed of the invention
- Engines:
Only low-voltage electric motors can be used in adjustable beds.
The alternatives are motors whose operation is based on their rotary shaft motion or spindle motors based on linear motion.
Low voltage DC, AC and servomotors, etc. are used in the control mechanisms of various small machines and devices, e.g. in small robotic arms.
The power of the motors can be increased by means of gearboxes and the rotational movement of the shaft can be converted into a linear movement by means of ball screws or the like, but their power is not sufficient for use in connection with the adjustable base structure of the bed of the invention.
Due to its operating voltage, high power and speed of movement, the linear spindle motor is optimally suitable as the motor used in the adjustable base structure of the bed of the invention.
Linear spindle motors provide safe, quiet and secure control movement thanks to their precise motion control.
The adjusting movement of the linear spindle motors is transmitted through the rotary cylinder structures of the invention to the lever arms of the components of the adjustable base structure which support and move the bed-level frame structure of the bed.
Spindle motors are commonly used in scissor mechanisms and lifting columns for the height adjustment of conventional adjustable beds.
See Figures Fig.22 to Fig.25. A rotary cylinder structure acting as a control mechanism for the components N of the pedestal structure of the invention, the operation of which is based on a single shank of a wide helical flange (12a) or narrow helical flanges (12b) of N30 wide spindle flanges (12a) .
Utilizing the variable lengths and thread densities of the spiral flanges and the constant stroke lengths and speeds of the linear spindle motors, the desired adjustment speed of the base structure & components (1a, 1b, 1c) of the invention is achieved. exercise mechanisms-> 35 - individual adjustment movement speeds used in mira solution applications.
The number of helical flanges may increase from one or two of the one or two shown in this description, and the number of thrust wheels (17a, 17b) arranged in the rotating cylinder structure increases accordingly, depending on the application.
The adjustable pedestal
the closest to the operating principle of the field rotation cylinder solution are the so-called tubular motors whose lightweight low-voltage applications are used, for example, in sunblinds. The structure of the tubular motor is shown in connection with Fig. 30. Low-voltage tubular motors (39) capable of - handling - larger loads are used, for example, in garage roller lift door mechanisms. See Fig. 31. However, the structural applications of known tubular motors operating only at 230V operating voltage / mains current would be strong enough to be used in the pedestal structure solution of the invention. The rotary cylinder structure of the adjustable pedestal structure of the present invention, in which the control motion of the linear spindle motor is converted into a rotational control motion, forms a new type of low voltage control mechanism solution with a high force / torque equivalent to a conventional AC motor drive. the principle of operation of which the solution of the invention is compared in this connection. This offers new application and operating possibilities for various machines and devices that previously operated with 230V operating voltage in places where their control motors have to operate at low voltage.
Control of the adjustable pedestal structure of the bed of the invention: - The electrical adjustments of the adjustable pedestal structure of the bed of the invention and the operation of their safety mechanisms are implemented by means of logic control. The adjustment functions of the adjustable pedestal structure can be selected individually according to the different applications of the beds and their different user groups: All adjustments to the height and tilt positions of the reclining structure made possible by the pedestal structure can be used, eg in hospital beds controlled by nursing staff or only some of them or by limiting the range of motion of their adjustments, e.g., in homes where bed users also independently perform N bed adjustments. The adjustment functions of the adjustable pedestal structure are complemented by the bed ergonomic back, N 30 pelvic, knee-bending and foot panels connected to the bed's sleeping structure, which are controlled, for example, by a control panel or hand control connected to the bed's structure. See Figure Fig.24. = The logic control unit (10) for the control motors of the pedestal structure is located in its lowest part (1a). The control panel is also used to set or change the settings for the base structure, such as the maximum height position required for the bed reclining structure in each> 35 application or the maximum tilt angle used for the Trendelenburg and Trendelenburg positions. See Figs. 16 to Fig. 18. For the control of the above-mentioned functions of the linear spindle motors located in the rotating cylinders of the components of the adjustable pedestal structure and the bed level.
The display panel for the functions of the engines and the electrical connection to the bed structure (34) are located in the foot structure (30) of the base structure. The display panel shows the operation of the bed structure adjustment motors and safety mechanisms and the codes for their possible faults. See Figure Fig.19. The adjusting movements of the rotating cylinders (2, 4, 6) of the adjustable pedestal structure of the bed of the invention and the lever arms (3, 7, 5a) connected thereto take place so that either they are all adjusted simultaneously or only the rotating cylinder and lever arms of one pedestal structure move alone. or the rotating cylinders and lever arms of the two components move together simultaneously, whereby the height position and tilt position according to each living or care situation of the bed reclining structure are reached or completed by flexible sets of adjustment movements of the base structure components.
Safety of use of the adjustable pedestal structure of the invention: The components of the adjustable pedestal structure of the invention (1a, 1b, 1c) and the bed frame level structure (31) can naturally be fitted with safety mechanisms covering all bed movement adjustment movements: 7 bases of the adjustable pedestal structure safety sensors located in the frame structure stop the downward adjustment movement when an obstacle occurs. The precise movement of the linear spindle motors locks the thrust cylinders (17a, 17b) which move the rotating cylinders - the wide helical flange (12a) or the narrow helical flanges (12b, 12c) at the end of the control movement, The bed structure remains stable and does not wobble in its adjusted position. The spindle motors do not move if they fail and the adjustable stand structure cannot collapse under any circumstances. The force of the available standard spindle motors is considerably greater than the force required to move the lever arms of the adjustable base structure of the bed of the invention, the need of which consists of the total weight of the different types of horizontal structure solutions supported by the base structure O and their personal load. The linear spindle motors ©, which act as control motors for the rotary cylinders (2, 4, 6), are assisted by N 30 gas springs (26, 27, 28) connected to the components of the adjustable pedestal structure, the location and operation of which will be described later, which significantly reduce the control motors and rotary cylinder structures. The gas springs also contribute to the safety mechanisms of the adjustable base structure, preventing a sudden downward descent of the sleeping structure in the event of a fault, which is not possible for the above-mentioned adjustable base structure due to the structural properties of the safe spindle motors used therein. The operating voltage of the linear spindle motors and other electrical components and equipment used in the bed structure is 12 / 24V. The adjustable base frame of the bed of the invention
The structure is a lifting device, as are the height-adjustment mechanisms of other adjustable beds, which are subject to the safety requirements imposed on them. The adjustable base structure of the bed of the invention is able to meet the international safety requirements set for it.
On the speed of movement of the lever arms connected to the rotary cylinders: Utilization of standard linear spindle motors and, thanks to the structurally simple spiral flange solution of the invention, adjustment of the lever the stroke length of the motor spindle and the length and thread density of the wide helical flange (12a) or narrow helical flanges (12b, 12c) supported on the inner surface of the body tube (11) of the rotation cylinders, which vary individually in the different rotation cylinders. Each of the rotating cylinders (2, 4, 6) of the component (1a, 1b, 1c) of the adjustable base structure and the lever arms (3, 7, 5a) connected thereto thus have its own independent speed of movement. For the various applications of the rotating cylinder solution of the adjustable base structure of the invention, the movement speeds of the lever arms suitable for each application can be implemented as described above. Converting the control movement of a linear spindle motor into a rotational motion of a rotating cylinder cylinder is supported by a wide helical flange (12a) or narrow helical flanges (12b) However, the force required to convert the control movement does not substantially reduce the torque of the rotating cylinders. The structure and operation of the rotating cylinders are shown in connection with Figs. 5, 6 and 6. Figures 11a to 11c and 14a to 14c show the basic positions of the lever arms (3, 7, 5a) of the components (1a, 1b, 1c) of the adjustable base structure O of the bed of the invention in different adjustment positions of the bed structure N frame structure (31).
SN 30 Description of the adjustment movements of the adjustable base structure of the bed of the invention: I Adjusting the height position of the reclining structure: = Slightly different movement speeds of the lower arm lever arms © (3) and the middle arm lever arms (7) of the invention are realized so that when adjusting > 35 teas (31) from the lowest elevation position (Fig. 11c and Fig. 15b) of the so-called to the treatment height (Fig. 11b and Fig. 16), the frame structure of the lying plane moves perpendicularly upwards along the axis / line (36) of the components of the adjustable base structure shown in the figures. If the lower and upper component of the adjustable pedestal lever arms
(3, 7) the speed of movement would be the same, it would cause a situation in which the frame structure of the bed frame would also move horizontally in the longitudinal direction of the bed towards the main side of the bed during the height-adjusting movement of the bed frame structure. The lateral movement is small, but still functionally disruptive. The problem is eliminated - by implementing individual movement speeds between the rotary cylinders. The maximum usable height position of the bed on the bed supported by the adjustable base structure can be chosen completely freely. Depending on the application or functional situation, it can be considerably larger than what is possible with traditional adjustable beds.
Adjustments for the Trendelenburg and anti-Trendelenburg tilting positions of the bed reclining structure: The tilting angle adjustment of the Trendelenburg position of the bed reclining structure is made flexible by the individual adjustment of the linear spindle motors of the rotating cylinders of the adjustable base structure. In connection with the Trendelenburg and counter-Trendelenburg adjustments, the maximum tilt angle and height position of the bed's sleeping frame structure can be selected according to the different functional situations, made possible by the independent adjustment movements of the various components of the adjustable base structure (1a, 1b, 1c). The tilting angles of the Trendelenburg position can be adjusted at all different height positions of the bed reclining structure, see Figs. 14c and Fig.14b. The tilt angle of the Trendelenburg position can be flexibly adjusted as desired by adjusting the lever arms (5a) of the upper component of the adjustable pedestal structure, e.g. from the horizontal position of Fig. 11b to the inclination angle of Fig. 14b and further by the central movement of the pedestal structure (1b). , in the pictures counterclockwise rotation movement. The counter-Trendelenburg positioning of the reclining structure is completed by means of the adjusting movement of the lever arms N (5a) of the upper component of the adjustable base structure, but the rotation of the lever arms then takes place in the opposite direction. Adjusting the counter-Trendelenburg position, at the lowest height position of the bed reclining structure, requires the lower I and middle components of the adjustable base structure to be adjusted slightly higher in height and the lever movement of the upper part of the base structure, followed by © the tilt angle of the counter-Trendelenburg position S can be further increased while its height position increases by> 35 - by adjusting the lower and middle components of the adjustable base structure. The largest counter-Trendelenburg position of the sleeping structure (31) is the so-called standing position, see Figs. 11a and 20. The positions of the components of the pedestal structure in the Trendelenburg and counter-Trendelenburg positions of the bed reclining structure are shown in connection with Figures 14a to Fig.14c and Figures 17 to 19. The tilt angles of the selected maximum Trendelenburg and anti-Trendelenburg lying positions are activated by changing the settings of the logic control that controls the rotation cylinder adjustments.
Adjusting the structure of the bed so-called to the standing position: Adjusting the frame structure (31) of the bed lying down. to the standing position (Fig.11a, Fig.20 and Fig.21) takes place in such a way that the rotating cylinders (2, 4) of the lower and middle structural part (1a, 1b) of the adjustable pedestal structure of the bed of the invention and the lever arms (3, 7) connected thereto ) is used to further increase the height position of the lying frame structure, e.g. the so-called Fig. Fig. 11b, Fig. 14a and Fig. 18. from the treatment height upwards, while the adjusting movement of the rotating cylinder (6) of the upper component of the adjustable pedestal structure and the lever arms (5a) connected to the horizontal structure increases the angle of inclination of the anti-Trendelenburg position of the horizontal frame structure. At the end of the adjustment movements described above, the frame structure of the bed's sleeping plane is the so-called in a standing position in which the bed user stands on an end plate (35) connected to the foot of the bed reclining structure. Adjustment of the sleeping frame structure from its basic position shown in Figures 11c and 15b or from any other position of the sleeping frame structure and height position of the bed. in the standing position and vice versa takes place by means of the logic control of the functions of the control motors (15a, 15b) arranged in the rotating cylinders (2, 4, 6) of the flexibly and steplessly adjustable base structure. Extreme positions of the bed reclining structure of the bed of the adjustable pedestal structure of the invention:> The adjustable pedestal structure solution of the bed of the invention enables practically unlimited adjustments of the height position of the bed and the reclining positions of its lying plane. Thanks to the adjustable pedestal structure solution of the bed of the invention, the sleeping plane structure of the bed Ni can be adjusted to the so-called frame structure of the sleeping plane N 30. from the standing position of the bed by further adjusting the rotation cylinder (6) of the upper component (1c) of the pedestal structure E and the lever arms N (5a) connected thereto to a horizontal plane (cf. Figs. 11a and Fig. 12a), or the bed frame structure can be respectively infinitely adjusts to different 2 heights and tilt positions between the maximum structural height described above and the lowest height position of the N 35 - adjustable pedestal structure. The adjustable pedestal structure of the bed of the invention also structurally allows the tilting angle of the Trendelenburg position of the bed reclining structure, which is a mirror image of the standing position of the bed. The user of the bed would then be fully head down on the lying surface - Compare Fig. 10a. The functionally far too large extreme positions of the bed reclining and care situations of the bed reclining structure, which are structurally made possible by the adjustable base structure described above, cannot naturally be used in beds. However, they can be utilized in connection with other applications of the adjustable pedestal structure of the bed of the invention. The limitless possibilities of adjusting the height and tilt positions of the bed reclining structure and their flexible variations illustrate the versatility of the completely new type of adjustable pedestal structure of the invention and the functionally decisive difference and advantage over the traditional bed reclining structures - support and adjustment mechanisms. The extreme positions of the adjustable pedestal structure of the invention allow the various components (1a, 1b, 1c) of the pedestal structure to be connected to each other by means of rotating cylinders (2, 4, 6) acting as chain-like adjusting mechanisms. In structural solutions based on the use of scissor mechanisms or lifting cylinders for traditional adjustable beds, the adjustment of the height and tilt angles of the reclining structure is limited by the structural dimensions of their adjustment mechanisms.
Gas springs assisting the adjustment motors of the adjustable pedestal structure of the bed of the invention: - The sleeping platform structures supported by the adjustable pedestal structure of the invention and the associated structures complementing other functional and ergonomic features of the sleeping planes and the bed's personal load form a heavy whole. The gas springs (26, 27, 28) connected to the lever arms (3, 7, 5a) of the components of the base structure significantly reduce the load on the components of the adjustable base structure and the rotary cylinder structures and control motors and thus help to stabilize the operation of the base control movements. The placement of the gas springs in the components of the adjustable pedestal structure of the bed of the invention is shown in connection with Fig. & Fig. 10 and their trajectories in different adjustment positions of the bed-lying frame structure of Fig. 11 to Fig. 11c and Fig. 12a to Fig. 13a. 13b in connection with N 30. The grooves (21c) in the mounting flanges = (21a) of the shafts (13b, 13c) inside the rotating cylinders (4, 6) I of the middle and upper components (1b, 1c) of the adjustable base structure allow free movement of the gas springs when the base structure is adjusted to different positions. hidden investment. When the bed-lying structure of the bed is the so-called bed. in the standing position, the torque / force on the structural members of the pedestal structure is at its maximum. The gas springs (26) supported on the foot structure (30) of the adjustable pedestal structure and connected to the lever arms (3) of its lower component (1a) also act as a mechanical safety mechanism of the control movement in question, stopping the control movement to its extreme position. The adjustable pedestal structure of the bed of the invention can be implemented with or without gas springs, since the power of the linear spindle motors alone is sufficient to move also structurally heavy bedding structures of different types during their adjustments. However, the connection of gas springs to the components of the adjustable base structure is - simple and inexpensive to implement. Utilizing them increases the service life of the pedestal adjustment motors and adjustment mechanism structures. The thrust of the standard gas springs is large and completely sufficient for use in connection with the adjustable base structure adjustment functions of the bed of the invention. By selecting the force of the gas springs, taking into account the weight of the different types of sleeping solutions supported by the bed reclining structure and the safety factor of the bed load, the adjustable pedestal structures can be optimized so that their lever arms are electrically operated in small arms.
5. Advantages of the adjustable bed structure solution of the bed according to the invention: The starting point of the present invention has been to develop a bed - adjustable bed structure with universal adjustment properties, which at the same time complements the ergonomic and functional features of the invention PCT / F12018 / 000007 / “Adjustable bed solution”. Together, the inventions form a completely new and universally valid adjustable bed solution for use by all different target groups. The structural solution of the present invention - the adjustable bed structure of the bed - enables the placement of an adjustable bed solution in the bed structure of the bed anchored to the bed structure of the bed included in the invention, also operating independently. There are solutions in traditional adjustable beds, - in which a wheelchair is connected to the sleeping structure of the bed, either through the> end of the bed structure or connected to the sleeping structure from the side. However, due to the structural solutions of the pedestal structures of these beds 5, their adjustment properties are very limited. The adjustable pedestal structure of the bed of the invention can also, as an independent solution, be connected to the sleeping N 30 level structure of almost any conventional bed solution to give them the added value brought by versatile adjustments. See Figure E in Fig.15a. The requirements for the functional properties of N beds for care, rehabilitation or home use vary greatly from simple applications D to functionally demanding and versatile solutions. The bed solutions made possible by the N 35 - adjustable pedestal structure solution of the bed of the invention, which are complete with adjustable and ergonomic properties and thus universally valid, are able to serve their users in all situations, even in future changing conditions as the bed user's mobility is impaired over time. The adjustable pedestal structure of the bed of the invention makes it possible to implement universal bed solutions which differ significantly in their adjustment and ergonomic properties to the advantage of traditional adjustable beds and the adjustment mechanisms used in them. The adjustable stand structure of the invention solves, for example, the significant functional shortcoming of traditional adjustable beds, the so-called implementation of the bunk bed function. Traditional so-called standing beds have been developed specifically for this function, which is why their other control features are limited. Even in the otherwise highly developed and otherwise versatile hospital care beds e1, the standing bed position of the reclining structure has not been able to be realized due to their - traditional control mechanism solutions. The standing position of the bed is needed in situations where the user of the bed cannot bend his body when entering or leaving the bed for various reasons, due to injury or, for example, after surgery. The adjustable beds implemented with the adjustable pedestal structure solution of the bed of the invention are suitable for use in all different applications from homes to hospitals. The adjustable pedestal structure, which supports the bed's reclining structure, enables all the various bed adjustment movements for demanding treatment situations, postures and physiotherapeutic rehabilitation and living positions. The invention makes it possible to implement a functionally and economically optimized bed solution for all different uses of beds and their different users.
