Definitions
- a rotating bed is known from practice, in which a reclining frame is arranged on a high adjustable base.
- the bed frame is connected to the base via a rotating hinge.
- the couch frame is essentially divided into three sections, a back section, a central section and a leg section.
- the leg section is divided into a proximal and a distal subsection.
- the lying frame can be transferred from a more or less stretched lying or bed position to a chair position.
- the reclining frame is brought into a transverse position by 90 ° in relation to the base from the reclining position.
- the central section and the proximal lower leg section form a seat for the patient.
- the distance from the floor to the top edge of the seat corresponds to the anatomical human condition. This means that the distance must not be greater than the distance from the back of the knee to the floor, otherwise a patient sitting on the bed would not have contact with the feet. Getting up would be difficult.
- the rotary hinge consists of a circular ring arranged on the head of the base made of an L-shaped angle profile.
- a strut cross runs below the circular ring and contains a vertically aligned bearing bush at the intersection of the struts.
- a pivot pin, which is connected to a frame of the rotary hinge, is rotatably seated in this bearing bush.
- the frame of the rotary hinge consists of bars which are arranged along the edges of a square, the edge length of which corresponds to the diameter of the circular ring. In the middle of the longitudinal spars are rollers that run on the top of the circular ring.
- the spars of the intermediate section of the reclining frame are rigidly connected to the square frame of the rotating hinge via stands.
- the height of the rotary hinge is relatively high, which means that the base rests directly on the floor without any clear space. i
- the base cannot be moved together for two reasons:
- the struts forming the base have certain minimum cross-sections so that they are able to absorb the forces that occur when the bed is loaded without deformation. After all, the bed must be dimensioned for a patient weight of approx. 180 kg.
- the other boundary condition that prevents the base from moving together further is the forces occurring on the drive device. The further the base is moved together, the shorter the lever arms on the individual crank levers, with the aid of which the base is stretched through the drive device.
- a further increase in the overall height in the known construction results from the fact that a distance must be provided between the lying frame and the frame of the rotary hinge, in which the drive devices for the leg section and the back section are to be accommodated.
- the required drives are located above the frame of the rotary hinge, since its interior is also filled with a cross brace due to the mounting of the axle pin.
- a rotary hinge which has a support ring, within which the turntable is located, to which the bed frame is attached directly or indirectly.
- the turntable is only connected to the base via the support ring, which means that no central journal is required. This means that the area inside the turntable is free. This free space enables parts of the drive devices for the back and the foot section of the reclining frame to be accommodated, which benefits the overall height.
- the swivel hinge of the swivel hinge is located within the support ring, which causes the vertical extension of the rotating hinge is additionally reduced compared to a sandwich construction in which the rotating stool is arranged exclusively above the support ring, as is the case with the prior art.
- the turntable is composed of two spars running parallel to one another in the longitudinal direction, which are rigidly connected to one another via cross struts.
- the cross struts are screwed together, which means that the width of the longitudinal bars can be adjusted at the same time. As a result, manufacturing tolerances can be compensated for without further notice.
- the support ring preferably has a U-shaped profile, so that the bearing means, which connect the turntable to the support ring, can engage in the U-profile. This can also contribute to a reduction in the overall height. Otherwise, the bearing means would have to act on both sides of the support ring in the case of a disk-shaped support ring in order to be able to transmit the upward transverse forces, that is to say the tensile forces, to the ring even without the journal.
- the bearing means preferably consist of an axle connected to the ends of the respective spar and a roller running thereon.
- the axial forces i.e. both the downward and the upward forces, can be transmitted.
- Such upward forces arise, for example, when the foot end of the reclining frame is loaded more than that Head end or when the reclining frame is in the chair position, because the anatomical reasons that the seat is then mainly in front of the vertical axis of rotation of the rotating hinge.
- radially supporting rollers are advantageously provided on the support ring. They serve to center the turntable in the support ring, which the usually cylindrical support rollers, which take over the axial forces, cannot achieve.
- a circular arc is used as the supporting ring, the arc length of which is less than 360 °.
- an axle pin is additionally provided, which, however, is located directly next to one side of the head of the base.
- the advantage of the second alternative is that in the chair position, the side of the reclining frame that is then adjacent in the head end does not move so strongly in the direction of the head end. It remains essentially at the level of the axis of rotation, since the axis of rotation is immediately adjacent to the relevant side of the reclining frame.
- the second alternative with the support ring not closed allows the use of extra-wide lying frames.
- the bed frame is divided into several sections that can be moved with respect to the central section. In combination with other rigid parts of the bed, this can result in dangerous crushing and shearing points. Even if these are permitted according to the relevant norms and safety regulations, since they were previously considered to be inevitable, it is advantageous if a new construction eliminates these crushing and shearing points, which were previously regarded as inevitable. This is particularly advantageous if the overall height is not adversely affected.
- an intermediate frame is used between the lying frame and the rotating hinge, which is significantly narrower than the width of the lying frame.
- a drive device acts on the slide and, on the other hand, a type of connecting rod that transmits the movements of the slide to the foot section of the reclining frame.
- the drive device in such known beds usually consists of an electric motor with a screw drive. If this screw drive were to attack the foot section directly, as in the prior art, it would have to perform a considerable pivoting movement. Accordingly, the distance between the upper edge of the base or the rotary hinge and the underside of the reclining frame must be selected in the prior art.
- the solution according to the invention avoids the pivoting movement of the drive device and reduces it to the connecting rod, which takes up much less space in the vertical direction.
- the space the pivoting movement takes place within which are moved to areas' where also space is available sufficiently without increasing the vertical height.
- the bed frame which is divided into several mutually movable sections, only forces the entire forces, which originate from the weight of the patient, to be transferred to the base via the intermediate section.
- the bed construction must be stable and stiff so that any elastic deformation is largely avoided, which under certain circumstances could lead to parts of the bed colliding with one another during the rotational movement. i
- the stability can be increased significantly if the
- Spars of the intermediate frame are braced against one another via at least two rigid struts. These two struts are located in vertically spaced planes approximately at the height, based on the longitudinal extent of the bed, at which the spars of the intermediate section of the bed frame are connected to the intermediate frame. This creates a kind of box construction that is very rigid with regard to the forces that occur.
- tabs are provided which run in the longitudinal direction of the respective spar and which form the hinge tabs.
- At least one circular disc-shaped spacer is arranged between each two hinge-forming tabs, which is preferably larger in diameter than the vertical extension of the respective longitudinal spar, so that squeezing and clamping points are effectively avoided in each pivoting position of the spars.
- the tabs can be an integral part of the spars.
- the spars are preferably square tubes which are provided at the ends with an approximately rectangular recess or notch. This creates tabs with a U-shaped cross-sectional profile that extend the full cross-section of the rooms.
- the back of the U-shaped profile represents the extension of the outer wall of the spar, while the side strips or legs of the U-shaped cross-sectional profile are formed by wall sections of the original pipe cross section.

- the care bed 1 has a bed border 2 with a head part 3, a foot part and side walls 5 and 6.
- the side wall 5 facing the viewer is in the lying position, as illustrated, at a distance from the floor, which means that there is a gap between the lower edge of the side wall 5 and the floor, which enables the nursing staff to put the tips of their feet under the bed.
- the side wall 5 is movably mounted and, in the armchair position of the nursing bed 1, moves into a downward position, as can be seen in FIG. 2.
- the special mounting of the side wall 5 is explained in detail, for example, in DE 199 12 937 A1. 2004/037147

- the two longitudinal spars 27 are connected to one another at the lower end at 28 via a cross strut.
- the two longitudinal spars 27 are connected by a strut 29 to which two mutually parallel guide rails 31 are fastened, which extend as far as the lower cross frame 28 2004/037147 are sufficient. As shown, they run at an angle to the longitudinal spar 27 and in such a way that they converge towards the foot end.
- the distance between the two guide rails 31 is significantly smaller than the distance between the two longitudinal spars 27. Compared to these, the guide rails 31 are offset inwards by approximately 20 cm.
- the foot section 17 consists of spars 32 which are raised on the base 8 via struts 33.
- All of the longitudinal spars 22, 25 and 27 carry pegs pointing towards the center of the bed, corresponding to the pegs 21, in order to connect molded rubber parts to the longitudinal spars 22, 25, 27, between which spring rods extend in a known manner.
- the high-adjustable base 8 includes an upper frame 34 and an under frame 35, which are connected to one another via a total of five toggle lever pairs 36 and 37.
- the toggle lever pairs 36, 37 are each located on one long side of the base 8, so that the corresponding toggle lever pairs 36, 37 on the other long side cannot be seen in the side view in FIG. 4.
- the pair of toggle levers 36, 37 is composed of an upper toggle lever 38 and a lower toggle lever 39.
- Each toggle lever 38, 39 is connected in an articulated manner to the upper and lower frames 34, 35 via a hinge 41 with a horizontal axis on the relevant bed side. All axes of the hinges 41 are axially parallel to one another. The axes of the hinges 41 are coaxial with the axes of the hinges 41 of the toggle levers 38, 39 which cannot be seen.
- FIG. 5 shows the design of the upper frame 34 in detail. According to it, two longitudinal spars 42 and 43 belong to it, which are rigidly connected to one another at the ends via cross struts 44 and 45. A further cross strut 46 is inserted in such a way that, as can be seen in FIG.
- oblique support struts 47 are welded in at the corners.
- the support struts 47 serve as a support for a ring 48 of the rotary hinge 9.
- the barrel or support ring 48 rests on the support struts 47 and is firmly connected to them. With its outer surface, it lies against the inside of the two longitudinal spars 42, 43 or the inside of the two cross struts 45 and 46 ' .
- the two longitudinal spars 42 and 43 contain the holes for the upper hinges 41 via which the upper toggle levers 38 are articulated to the upper frame 34.
- the lower frame 35 basically has a shape similar to that of the upper frame 34, ie it is composed of two longitudinal bars 49 which are connected to one another via cross braces which cannot be seen.
- the cross struts of the lower frame 35 are located below the cross struts 44 and 45 of the upper frame 34.
- the lower longitudinal spars 49 which are parallel to the longitudinal direction of the bed, are extended over the longitudinal extent of the upper frame 34 as shown and provided with feet 51 at the end. With the help of a total of four feet 51 located at the corner points of a rectangle, the base 8 and thus the entire bed frame 7 is on the floor. This form of stand-up creates a space of approx. 12 cm between the lower frame 35 and the floor, so that nursing staff can 2004/037147
- the nursing staff can thus adopt an ergonomically favorable posture by being able to approach the nursing bed 1 so closely that it can additionally be supported on the bed border 2 with the lower leg. As a result, the back muscles and thus the spine are significantly protected when the posture is bent forward.
- the two toggle lever pairs 36, 37 on each side of the base 8 are each coupled to one another by an associated coupling strut 52, 53.
- Each coupling strut 52, 53 is, as shown, with the knee joint 54 of each toggle pair 36,
- the drive motor 57 is supported at its end remote from the tab 56 on a cross strut which connects the two longitudinal spars 49 to one another approximately below the cross strut 44.
- the drive motor 57 is a standard spindle motor. With the help of a permanently excited motor 59, an unrecognizable snow crawler gear driven.
- the worm wheel is rotatably connected to a screw spindle.
- a threaded nut runs on the screw spindle, to which a lifting tube 61 is attached in a tensile and pressure-resistant manner and runs coaxially in a guide tube 62.
- the free end of the lifting tube 61 carries a fork head which is deflected at the tab 56.
- Another fork head is located at the opposite end of the motor housing, in which the motor is started with the corresponding direction of rotation.
- the lifting tube 61 By starting the motor with the corresponding direction of rotation, the lifting tube 61 is either retracted into the guide tube 62 or advanced out of the guide tube. By advancing the lifting tube 61, the cross strut 55 moves in the direction of the head end of the bed. As a result, the lower toggle lever 39 of each of the toggle lever pairs 36 and 37 is raised, since all of these are kinematically connected to one another via the horizontal coupling strut 52, 53 or the cross strut 55. The uprighting movement of the lower toggle levers 39 is transmitted via the inclined coupling struts 58 to the upper toggle levers 38 of the toggle lever pairs 37 located at the foot end. As a result, the toggle levers 38 of the rear toggle lever pairs 37 also straighten up. This movement is finally also transmitted to the pair of toggle levers 36 located at the head end.
- the kinematics ensure that the upper frame 34 always remains parallel to the lower frame 35.
- the vertical movement of the upper frame 34 does not result in any significant displacement of the upper frame 34 in the longitudinal direction of the care bed 1 within the lifting range for which the base 8 is constructed.

- the longitudinal spar 69 is provided with corresponding flat bars 73 and 74 which also end at a distance from the longitudinal spar 68.
- the struts 71 ...
- the strut 72 corresponds to the strut 73 and the strut 71 to the strut 74
- the contact surface between the struts 71 and 73 is at the same distance from the adjacent end of the spar 68 as the contact surface between the struts 72 and 74. Because of this arrangement, the longitudinal spars 68 and 69 ideally form the edges of a square that goes into the ring 68 fits in with a little play.
- the struts 71 ... 74 are screwed together by a total of four screws 75 ... 78.

- each journal 79 ... 83 there is a cylindrical roller 84, which fits with little play between the legs 65 and 66 of the ring 48 when the turntable 64 is installed.
- the rollers 84 serve as idlers that transmit the vertical force between the ring 78 and the turntable 74.
- the idler rollers 84 are freely displaceable radially outwards on the journal 79. A shift radially inward beyond the position shown is prevented by an abutment shoulder which is formed on each of the axle journals 59 ... 83.
- the radial guidance within the ring 48 is provided by four disk-shaped rollers 85.
- the rollers 85 run in assembled state of the turntable 64 depending on the radial load against the inward-facing cylindrical surface of the back 67.
- the axes of rotation of the guide rollers 85 are axially parallel to one another and, ideally, they lie on the corners of a square whose diagonal length is smaller by the diameter of the guide rollers 85 than the inside diameter of the ring 48 measured on the inside of the back 67.
- a total of four bearing blocks 86, 87, 88 and 89 are provided for connecting and holding the guide rollers 85.

With the help of screws 91 they are secured in the bearing blocks 85 ... 89. Only the guide roller 85 seated in the bearing block 89 is radially adjustable for the purpose of radially adjusting the effective diameter of all four guide rollers 85, which is why the opening for the screw 91 is an elongated hole 92 only here.
- two angle profiles 93 and 94 are attached on the outer sides of the two longitudinal spars 68 and 69.
- One of the two legs of the legs 95 is also welded to the outside, while the other leg 96 is flush with the top of the respective longitudinal spar 68, 69.

- An axle bolt 140 through which two rollers 141 are rotatably mounted outside the fork head 139, passes through mutually aligned bores in the fork head 139 and the end of the lifting tube 132.
- the rollers 141 run in the guide rails 137 and 138. This effectively prevents the connection point between the fork head 139 and the lifting tube 132 from buckling.
- the intermediate frame 10 is fastened to the turntable 64 with the aid of two angle flanges 143, of which only one can be seen in FIG. 8 because of the illustration.
- the angle flanges 142 are welded to the outside of the longitudinal spars 106 and 107, while their other leg 143 is flush with the underside of the respective longitudinal spar 106, 107.
- a total of four elongated holes 144 are contained in the legs 143, which are aligned with elongated holes 145 in the legs 96 of the turntable 64.
- the elongated holes 145 are directed outwards, ie its longitudinal axis is perpendicular to the adjacent longitudinal spar 68, 69, while the elongated holes 144 are parallel to the pair of longitudinal spars 106, 107.
- the intermediate frame 10 on the turntable 64 can be adjusted in the longitudinal direction of the bed.
- the intermediate frame 10 can be fastened to one another in any possible adjustment position of the two longitudinal bars 68 and 69 of the turntable 64.
- the two cross struts 109 and 110 there is a motor bearing 146, which is fastened to a pillar 147 projecting downwards.
- the pillar 147 is fastened with a flat side to the two struts 109 and 110. In the assembled state, it protrudes into the space of the turntable 64 which is delimited by the longitudinal struts 68 and 69 and the connecting struts 71 ... 74. This space also accommodates the parts of the drive motor 133 which project downwards.
- the vertical extent of the intermediate frame 10 is limited to approximately 5 cm plus the ceiling of the struts 110 and 111. These have a material thickness of approximately 5 mm.
- the rotary hinge 9 is assembled as follows: after the base 8 with the inserted ring 48 has been fully assembled, the bearing blocks 86 ... 8 are fitted with the guide rollers 85. The screw 91 in the slot 42 is set to the smallest radial distance. In addition, the support rollers 84 are slipped onto the axle journals 79 ... 83. Then each longitudinal spar 68, 69 is inserted individually into the interior as it is delimited by the ring 48. For this purpose, the support rollers 84 connected to the longitudinal beam 68 and the associated guide rollers 84 are inserted into the gap between the two Legs 65 and 66 threaded.
- the two diametrically opposite guide rollers 85 in the bearing blocks 86 and 88 are now at a distance from one another which corresponds approximately to the diameter of the ring 48 in the region of the inside 67. In this position, the guide roller 85 also bears against the back 76 in the bearing block 87 with little play.
- the screw 91 in the slot 92 is adjusted until the associated guide roller 85 is also a short distance from the back 67.
- the turntable 64 is mounted in this way within this ring 48 and adjusted with respect to the radial clearance. It has little radial air in the guide and support ring 48.
- the axial air is defined by the diameter of the support rollers 84 in relation to the distance between the legs 65 and 66.
- These rollers are cylindrical rollers and consist, for example, of Low-exercise PTFE, which has sufficient load-bearing capacity for rollers of this type.
- the height of the ring 48 measured over the outside of the two legs 65 and 66 is approximately 30 mm.
- the upper side of the profile legs 96 which points upwards in the normal position of use of the bed 1, projects about 5 mm above the upper side of the upper leg 66 of the ring 48.
- the rest of the turntable 64 disappears in and under the ring 48.
- the rotary hinge 9 is therefore only over the gap required to move the intermediate frame 10 over the top of the ring 48 and thus also over the top of the upper frame 34.
- the intermediate frame 10 is fastened on the turntable 64, for which purpose the flanges 143 are placed on the flanges 96.
- the shaft 118 lies in the direction of the foot end of the bed 1.
- the intermediate frame 10 is screwed onto the turntable 64 with the aid of 4 screws which are not shown in the drawings for reasons of clarity.
- the screws lead through the openings 144, 145 aligned in pairs.
- the two lower connecting struts 109 and 112 do not project downwards over this underside of the intermediate frame 10.
- the motor 97 can be mounted through the openings in the intermediate frame 10 which are delimited in the longitudinal direction by the struts 109 and 110 or 108.
- the lifting tube 103 is connected to the motor abutment 98 or the motor abutment 99.
- These two motor abutments 98, 99 have the same radial distance of approximately 10 cm from the vertical axis of rotation, which is symbolized in FIG. 6 by a cross 148.
- the longitudinal bars 25 of the thigh section 15, which are connected to one another via the strut 26, are hinged to the foot-side ends of the two longitudinal bars 18 and 19.
- the longitudinal bars 27 of the lower leg section 16 are in turn attached to these.
- the rollers 122 are then threaded into the guide rail 31 by lifting the thigh and lower leg sections 15, 16.
- the motor 133 which is coupled to the connecting rod 131 via the fork head 139, and the shaft 118 are then mounted in the upper frame. During assembly, the two guide rollers 141 are threaded into the associated guide rails 137 and 138.
- the back section 14 is now also attached to the central section 13.
- On Associated drive motor 149 is attached to the motor abutment 146 and connected with its lifting tube 151 to a coupling bracket 152 which sits on the strut 24.
- the strut 24 is positioned such that it rests on the longitudinal spars 106 and 107 when the back section 14 is aligned horizontally and the motor abutment bracket 152 is located within the opening of the intermediate frame 10, which is delimited at the head end by the cross strut 108. Parts of the motor 149 protrude into the turntable 64.
- the lying position according to FIG. 1 is initially assumed.
- base 1 is maximally moved together, i.e. the lifting tube 61 is withdrawn in the guide tube 62.
- the toggle lever pairs 36, 37 are folded up to the maximum.
- the intermediate frame 10 lies in the longitudinal direction of the bed 1.
- the back section 14 is lowered and lies with its cross strut 34 on the longitudinal spars 106, 107 of the intermediate frame 10.
- the levers 119, 120 are brought into a position in which the lower leg section 16 extends in a straight extension of the back section 14 or the foot section 17.
- the care bed 1 has no pinch points accessible from the outside.
- the support points on the intermediate frame 10 are moved inwards by approximately 20 cm relative to the outer edge of the mattress 12 and are therefore not accessible.
- the patient can optionally choose the back section 14 raise. To do this, he sets the drive motor 149 in motion using a manual control. Its lifting tube 151 is extended and pushes the back section 14 upwards. The force flow that occurs closes via the struts 110 and 109 of the intermediate frame 10. If necessary, the turntable 64 can also be used for further support if the pillar 147 is brought into contact with the strut 71 during assembly. A further support of the pillar 147 is achieved in this way, so that a load of the order of 80 kg can be lifted on the upper cross strut 23 of the back section 14.
- the lower leg section 16 is raised by the user starting the motor 133.
- the lifting tube 132 is extended and pushes the connecting rod 131 in the direction of the shaft 118.
- the latter is rotated in order to pivot the levers 119, 120 upwards and to press the lower leg part 16 up.
- the lower leg section 16 is simultaneously pulled up when the levers 119, 120 are swiveled up to the central section 13.
- the thigh section 15 is also inclined upward as shown.
- the patient wants to be brought into a position by the nursing bed 1, similar to a healthy person sitting on the edge of the bed, he first brings the lower leg and the thigh section 15, 16 into the position according to FIG. 3.
- the back section 14 becomes brought to a position of approx. 45 °, so that when turning afterwards there is no excessive projection over the bed outline.
- the base 8 moves up until the underside of the intermediate frame 10 can be freely rotated above the upper edge of the two side walls 5, 6.
- the lifting motor 57 is stopped and instead the rotating motor 97 assigned to the rotating hinge 9 is started. Its lifting tube 103 retracts and rotates the intermediate frame 10 together with the lying frame 11 located thereon by 90 ° either to the left or to the right, depending on which abutment 98, 99 the rotary motor 97 is articulated.
- the lifting motor 57 is started again in order to move the base 8 together to its smallest position.
- the underside of the intermediate frame 10 engages with the upper side of the side wall 5 and presses it down.
- the motor 133 After reaching the lowest position, the motor 133 is started in such a way that the lifting tube 132 is drawn into the associated guide tube. This movement pulls the connecting rod 133 back, causing the levers 119, 120 to pivot downward. This downward pivoting of the levers 119, 120 has the effect that the foot section is also pivoted downwards until it reaches the end position according to FIG. 2. Finally, the patient can make the back section 14 steeper as required. A steeper position during turning is generally felt to be uncomfortable with the feet raised.
- the length of the lower leg section 16 in the chair or armchair position measured from the upper edge of the mattress 12 should not be longer than the length of the lower leg in a normal-sized person. Otherwise he could not reach the floor with the soles of his feet. Since the base 8 of the new bed can be moved together very small and the height of the assemblies from the rotary hinge 9, the intermediate frame 10 and the lying frame 11 is extremely low, about 12 cm remain in the armchair position. left around which the subframe 35 can be raised.
- the proportioning of the thigh section 15 and the lower leg section 16 must be based on the human anatomy.
- the lower leg section 16 would be too short for the normal lying position, which is why the foot section 17 is provided, which carries its own mattress section.
- a patient With the help of the nursing bed 1, a patient can move from the lying position into a sitting position across the bed without any physical effort and without having to resort to the help of nursing staff.
- the care bed 1 is also suitable as a stand-up aid.
- the patient can first be brought into a position according to FIG. 2. Then he leans forward out of the bed and at the same time actuates the height adjustment of the base 8. He is thereby raised on the buttocks, which means that he needs less strength to get into the standing position.
- Such support is very helpful in patients with multiple sclerosis or muscle weakness. A patient who would otherwise be dependent on outside help to get out of bed can do so with the help of care bed 1 without outside help at his own discretion.
- FIG. 11 shows an enlarged exploded view of a hinge 160, as is used, for example, between the longitudinal spar 19 and the longitudinal spar 22.
- both longitudinal spars 19, 22 consist of a square tube with an edge length of approximately 30 mm.
- the longitudinal spar 22 At the end is the longitudinal spar 22 with a recess
- the recess 161 protrudes a little in the direction of the longitudinal direction of the spar 22 and a little in the transverse direction.
- the depth of the recess 161 in the transverse direction is less than the width of the longitudinal spar 22.
- An imaginary hinge bracket 162 is formed, the length of which corresponds to the depth of the recess 161 in the longitudinal direction of the spar 22. This hinge tab
- the tab 162 is reinforced at the edges by webs through the remaining sections 163 and 164 of the profile tube wall.
- the tab 162 takes on the overall shape of a U-profile in the area of the hinge 160.
- a through hole 165 is located in the middle of the tab 162.
- the adjacent end of the spar 19 is provided in the same way with a notch 166, the notch 166 pointing to the opposite side.
- the disc 168 is provided on only one of its end faces with two grooves 169 and 170 which receive the webs 163 and 164.
- the disc 167 contains grooves 171, 172 in only one end surface for the corresponding webs of the spar 19.
- the diameter of the two discs 167 and 168 is dimensioned such that the tabs 162 do not have their free end over the outer peripheral surface of the discs 167 and survive 168.
- the hinge 160 shown is assembled by pushing the associated washer 168 or 167 onto each bracket 162.
- the stiffening webs 164 and 163, which, moreover, pass in one piece and continuously into the profile tube which forms the spar 19 or 22, are received entirely in the grooves 169, 170 or 171 and 172.
- a cylindrical bore 173 contained in each disc 167 and 178 is aligned with the relevant 165 in the tab 162.
- a screw 174 is inserted through these bores and is secured on the other side with a nut (not shown). The hinge 160 is preloaded without play by the screw 174.
- the disks 167 and 168 act, so to speak, as a sliding and filling piece in order to fill the open space within each tab 162 and to form a sliding surface for the respective other disk 167, 168. Since the washers are also larger in diameter than the thickness of the profile tube for the spars 19 and 22 there is also no shear point when the hinge 160 is bent, since the two disks 167 and 168 lie on one another with the same diameter.
- the hinge 160 shown is capable of absorbing pressure and tensile forces to a considerable extent. Such considerable tensile forces occur, for example, at the connection between the central part 13 and the back section 14.
- FIG. 12 shows a modification with a rotary hinge 9, the support ring of which has a radius which is essentially the clear width between the two longitudinal spars 42 and 43 corresponds.
- FIG. 12 shows a top view of the upper frame 34 with the two longitudinal spars 42 and 43, which are connected at both ends via the cross struts 44 and 45.
- the cross strut 46 is omitted.
- the rotary hinge 9 has a support ring 48, which begins in the inner corner between the longitudinal spar 43 and the cross strut 44, runs from there in a circular arc to the inside of the longitudinal spar 42 and extends over the point of contact with the longitudinal spar 42 by approximately 45 ° extended.
- the support ring 48 has a total length corresponding to a centering angle of approximately 135 °.
- the support ring 48 is connected to the upper frame 34 in the area of the inner corners between the cross strut 44 and the longitudinal spar 43 on the inside of the longitudinal spar 42 and via further struts 180, 181 and 182.
- the turntable 64 only has one of the two longitudinal spars, for example the longitudinal spar 68, from which two triangular connecting struts 183 and 184 emanate in the direction of the longitudinal spar 43.
- the connecting struts 183 and 184 end at a hub 185, with which they are rigidly connected.
- the hub 185 is rotatable on a bearing block located underneath, which is fastened to the inside of the longitudinal spar 43.
- the axis of rotation of the hub 185 corresponds to the center of the support ring 48.
- the axle journals 79 and 81 on which the cylindrical support rollers 84 are rotatably arranged.
- the support rollers 84 engage, as before, between the legs 65 and 66 of the support ring 48, which also has the cross-sectional profile corresponding to "A" from FIG. 5 in the embodiment according to FIG.
- the mounting flange 96 with the mounting holes 145 is provided on the outside of the longitudinal spar 68.
- a further fastening flange 186 is attached to the top, which faces the viewer, of the two triangular connecting struts 183 and 184.
- the fastening flange 184 lies in the same plane as the fastening flange 96 in relation to the plane as defined by the support ring 48.
- the intermediate frame 10 is mounted on the two mounting flanges 96 and 186 as before.
- the intermediate frame 10 when using the intermediate frame 10, if it is fastened on an upper frame according to FIG. 12, it rotates around one; Axis that is directly adjacent to one of the two longitudinal spars.
- the advantage of this arrangement is that the bed frame rotates around a point that is very closely adjacent to the outer edge of the bed 1.
- Another advantage of the arrangement according to FIG. 12 is that beds can also be realized in which the bed width exceeds the customary 90 cm.
- a nursing bed has a height-adjustable base, in which a rotating hinge is largely recessed.
- the rotating hinge connects the base with an intermediate frame on which the actually lying frame is built. This creates a bed that has a very low overall height after deducting the height of the adjustable feet, so that in the lowest position the top edge of the mattress corresponds to the length of the lower leg from the floor, while at the same time there is still space below the base to the floor.
