Definitions

  • the invention relates to a slatted frame or similar mattress holder, in particular for a bed, with a head part serving to support at least the head of a person and a foot part serving to support at least the legs and feet of a person, wherein the head part can be pivoted in relation to the foot part about an axis of rotation running transversely to the longitudinal extension of the head and foot parts.
  • a mattress holder When used as intended, a mattress holder serves to support a mattress, typically a bed mattress.
  • the mattress holder can be plate-shaped, as a grid or in some other way.
  • a frequently used design is the slatted frame. This typically has a number of individual slats that are arranged at a distance from one another in the lengthwise direction of a mattress to be supported. Designs are also known from the prior art in which the slats of a slatted frame are equipped with individual spring elements on the mattress side. This can increase the comfort of lying down even further.
  • a generic slatted frame or a generic mattress holder has a headboard on the one hand and a footboard on the other.
  • the headboard serves to support at least the head of a person
  • the footboard serves to support at least the legs and feet of a person.
  • the headboard is typically shorter than the footboard in the longitudinal extension of the head and footboard.
  • the head part can be pivoted in relation to the foot part, namely about a rotation axis running transversely to the longitudinal extension of the head and foot parts.
  • This pivoting capability allows the head part to be moved from a horizontal position to a position inclined relative to the foot part when the slatted frame is used as intended.
  • a person supported by the slatted frame thus no longer takes a lying position, but rather a reclining position. upright position according to the angle of inclination.
  • the invention proposes that the head part is designed to be translationally movable in relation to the foot part in the direction of the longitudinal extension of the head and foot parts.
  • the slatted frame according to the invention has a head part which is not only pivotable in relation to the foot part, but is also designed to be movable in translation.
  • the foot part is designed to be at least partially fixed in the translational direction of movement of the head part, for example in that the slatted frame providing the head part and the foot part is accommodated in a bed frame of a bed.
  • the head part is not designed to be fixed, but rather can be moved in relation to the foot part according to the invention, namely on the one hand it can be rotated and on the other hand it can be moved.
  • the state of the art inevitably results in a V-shaped arrangement of the head and foot parts.
  • a mattress lying on the slatted frame is compressed, which can damage the mattress or even destroy it.
  • the head part also moving in a translational manner during a pivoting movement.
  • the possibility provided by the invention of moving the head part back and forth in a translational manner The ability to move the headboard is used to move the headboard away from the footboard when the bed is raised, or to move the headboard towards the footboard when the bed is lowered.
  • the headboard is designed to be movable lengthwise relative to the footboard, particularly depending on a twisted position.
  • a drive unit is also provided which is operatively connected to the head part.
  • This drive unit is designed to move the head part back and forth in a translational manner in relation to the foot part.
  • a driven movement of the head part in relation to the foot part takes place, whereby the head part is moved away from the foot part in a translational manner and at a later point in time is moved towards the foot part or vice versa.
  • a relative translational mobility of the head and foot sections is not unknown in the state of the art.
  • the EN 10 2018 009 934 A1 a slatted frame construction, according to which, in contrast to the present invention, a fixed head part and a foot part that can be moved relative to it are provided.
  • this previously known construction is not without disadvantages, which is why, in a departure from this prior art, the invention proposes to move the head part rather than the foot part.
  • the foot section moves in relation to the head section because the motor intended to drive the foot section is located in the area of the foot section and not in the area of the head section. This enables a direct connection of the motor to the foot section that is to be moved in the intended use.
  • the motor is located in the area of the foot section arranged to avoid unwanted noise and/or vibration transmission to the headboard.
  • the design according to the invention in contrast to this prior art, provides for the head section rather than the foot section to be movable, thereby knowingly accepting the disadvantage of a more complex construction.
  • the design according to the invention thus has the synergistic effect of, on the one hand, realizing relative mobility between the head section and foot section and, on the other hand, forming the foot section from several sections that can be pivoted relative to one another, so that a particularly comfortable transfer of the slatted frame from a lying position to a sitting position and vice versa is possible.
  • the slatted frame according to the invention is therefore particularly suitable for use in combination with hospital and/or nursing beds.
  • the design according to the invention makes it possible to pivot the head part in a known manner in relation to the foot part. It is also possible to move the head part in a translational manner in relation to the foot part. Since, in contrast to the prior art, it is the head part that is moved, not the foot part, the design according to the invention also makes it possible to not form the foot part in one piece, but instead to provide a plurality of sections that can pivot relative to one another.
  • the slatted frame according to the invention can therefore be aligned as required to assume a corresponding sitting and/or lying position.
  • a mattress is preferably used which has a buffer section which separates a mattress-side head part from a mattress-side foot part. A movement of the head part of the slatted frame can thus be transferred to a person lying on the slatted frame with the mattress in between.
  • the drive unit has a motor arrangement provided on the foot part.
  • the motor arrangement is preferably arranged in the area of the foot part in order to avoid undesirable noise and vibration transmission in the direction of the head part.
  • the drive unit has a gear arrangement that couples the head part to the motor arrangement.
  • This gear arrangement couples the movement of the motor arrangement and the head part, so that when used as intended, the head part can be driven by the drive unit in the manner already described.
  • the disadvantage of a gear arrangement that has to be provided to transmit power to the head part is consciously accepted in order to achieve the additional advantage of being able to make the foot part separately adjustable.
  • the head part is preferably shorter than the foot part. This means that the head part also has less mass than the foot part, which advantageously allows a smaller motor arrangement.
  • the design according to the invention is less susceptible to wear due to the movable arrangement of the head part and not the foot part, since the foot part has to absorb the main load of supporting the weight of a person lying on the slatted frame during normal operation.
  • the design according to the invention can therefore be designed to be much more delicate than the design known from the prior art, while increasing its service life. Unwanted noise and vibration transmission to the head part can be avoided by using a gear arrangement as described above.
  • a further drive device is provided which is operatively connected to the head part and is designed to pivot the head part in relation to the foot part about the axis of rotation running transversely to the longitudinal extension of the head and foot parts.
  • An additional drive device is provided. This is operatively connected to the head section and enables the head section to be pivoted in relation to the foot section using a motor.
  • a control device which is designed to move the head part in a translational manner by means of the first drive device as a function of a pivoting movement of the head part caused by the second drive device.
  • This advantageously creates a mattress compensation which prevents the mattress from being accidentally compressed when the head part is pivoted. This extends the lifespan of a mattress and improves the lying and sitting comfort of a person using the slatted frame as intended.
  • the headboard is spaced apart from the footboard in the non-pivoted position in the longitudinal direction as far as possible.
  • the gaps between the headboard and footboard are thus minimized for a mattress to be positioned precisely and securely.
  • the head part is spaced apart from the foot part in the fully pivoted position in the longitudinal direction of the head and foot part as far as possible. This provides the maximum possible mattress compensation, which, as already described, helps to minimize the load on the mattress caused by pivoting of the head part.
  • the particular advantage of the design according to the invention is that a translational displacement movement of the head part is possible depending on a rotational movement of the head part.
  • the head part moves away from the foot part when the head part is raised, whereas it moves towards the foot part when it is folded down in the direction of a horizontal position.
  • the angle-dependent displacement movement can be specified by control technology. This makes it possible in particular not to provide a proportional dependency, but rather one that is tailored to requirements, particularly with regard to the mattress used.
  • the foot part has a plurality of sections that can be pivoted relative to one another.
  • three, four or five sections can be provided.
  • the sections are designed to be pivotable by motor, with one motor preferably being provided for each section, which makes it possible to pivot all sections of the foot part independently of one another. Any sitting and lying position can thus be achieved.
  • one of the sections of the foot part is designed to be fixed, with the head part being adjacent to this section.
  • the section of the foot part that supports the buttocks of a person using the slatted frame as intended is designed to be fixed.
  • the head part supports the upper body and head
  • the foot part supports the thighs, lower legs and feet. Due to the adjustment option of the foot part, the thighs, lower legs and feet can be positioned as desired.
  • the slatted frame according to the invention has a frame which supports the headboard and the footboard, the frame having an outer frame and an inner frame.
  • a frame is used to hold or support both the head section and the foot section. According to the invention, this is designed in two parts and has an outer frame on the one hand and an inner frame on the other, with the inner frame being surrounded by the outer frame.
  • the division of the frame into an outer frame and an inner frame makes it possible in a simple way to construct the head part in relation to the foot part so that it can be both pivoted and moved in translation.
  • a one-piece fixed frame is used, which accommodates the foot part, which is designed as a running frame, in a movable manner.
  • the fixed frame according to the invention is not designed as a single piece, but instead has an inner frame on the one hand and an outer frame surrounding the inner frame on the other.
  • the outer frame and the inner frame jointly support both the head part and the foot part.
  • a slide is provided in this context which is arranged on the inner frame so as to be movable in the longitudinal direction of the frame, with the head part being arranged pivotably on the slide.
  • the slatted frame according to the invention therefore has a two-part frame and a slide.
  • the slide is arranged so as to be movable on the inner frame of the frame. When used as intended, a translational movement of the slide in relation to the inner frame and thus also in relation to the frame as a whole is permitted.
  • the head part of the slatted frame according to the invention is arranged on the carriage. This enables the head part to be moved in a translational manner in relation to the foot part. This is because a movement of the carriage also leads to a movement of the head part due to the arrangement of the head part on the carriage, and this in relation to the frame, and therefore also in relation to the foot part, which is supported by the frame.
  • the head part Since the head part is pivotably mounted on the carriage, it is also possible to rotate the head part in relation to the carriage and thus also to the frame. As a result, the head part can be both rotated and moved in relation to the foot part in the manner already described.
  • the head part can move back and forth both in the non-pivoted position of the head part and in the pivoted position of the head part. This is because the possibility of moving the head part on the one hand and the possibility of rotating the head part on the other hand are decoupled from one another in terms of movement, namely by the head part being pivotably mounted on the carriage on the one hand and the carriage being movable on the inner frame on the other.
  • This possibility of moving the head part makes it possible to enable mattress compensation, i.e. when the head part rotates, the carriage supporting the head part is also moved, so that a rotational movement of the head part in relation to the foot part does not lead to an unwanted buckling load on the mattress supported by the head part and foot part in the transition area between the head part and foot part.
  • the design according to the invention therefore offers the advantage of realizing automatic mattress compensation between the head part and foot part.
  • the EN 10 2018 009 934 A1 Previously known construction is not able to produce this positive effect.
  • the foot part section of the foot part facing the head part has slats designed to be movable in the longitudinal direction of the frame.
  • the foot part can have several foot part sections.
  • three foot part sections can be provided, namely a first foot part section close to the head part, a second foot part section remote from the head part and a third foot part section which is arranged between the first foot part section and the second foot part section.
  • the foot section facing the head section i.e. the foot section of the foot section adjacent to the head section
  • the advantage of this design is that if the head section twists, a gap that is too large between the head section and foot section can be automatically compensated for by the movable slats of the relevant foot section moving towards the head section. This ensures secure support for the buttocks of a person lying in bed or a person lying on the slatted frame.
  • the movable designed slats of the foot section are coupled together in terms of movement with the interposition of a towing device.
  • the slats designed to be movable are thus mechanically coupled together so that a movement of one slat is transferred to the other slat and vice versa. In this way, a targeted movement of both slats is ensured in a structurally simple manner without the need for a separate motor drive.
  • the forced coupling provided according to the invention means that the preferably two slats move together.
  • the slat next to the head section is coupled to the head section in terms of movement so that a movement of the head section is transferred to this slat and then from this slat to the other slat adjacent to it.
  • "too large a gap” means a gap that can no longer guarantee secure support for the mattress held by the slatted frame in the transition area between the head section and the foot section.
  • the foot part section of the foot part adjacent to the foot part section is arranged on the outer frame so as to be pivotable about an axis of rotation.
  • the foot section of the foot section adjacent to the head section is arranged on the outer frame and can be rotated.
  • the rotatable arrangement allows the foot section to be pivoted in relation to the frame if necessary, which offers the possibility of a person supported by the slatted frame adopting a sitting position other than a lying position.
  • This rotatable foot section arranged on the outer frame serves in particular to support the thighs of the legs of a person supported by the slatted frame.
  • the foot section of the foot part adjacent to the foot section arranged rotatably on the outer frame is arranged on this foot section so that it can pivot about an axis of rotation.
  • the foot section of the foot part opposite the head part is therefore not pivotable on the head part side. on the frame, but is arranged so that it can be pivoted on the adjacent foot section.
  • This foot section is used in particular to support the lower legs of a person who is supported by the slatted frame.

This is supported on the one hand by the inner frame and on the other hand by the carriage. When used as intended, a motor-driven relative movement takes place between the carriage and the inner frame, which leads to a relative movement between the head part and the foot part, since the head part is arranged on the carriage, which means that the head part is carried along when the carriage moves.
  • the outer frame has a longitudinal extension that exceeds the longitudinal extension of the inner frame.
  • the outer frame preferably extends over the entire length of the slatted frame.

  • the foot part section 8 is coupled in terms of movement to the frame 22 with the interposition of coupling elements 69, as can be seen in particular from the illustration according to Fig.7
  • the coupling elements 69 are arranged at the other end on a tab 68 provided by the cross member 27 of the outer frame 23, as is particularly shown in the illustration according to Fig. 15 can be recognized.
  • the foot section 7, which is articulated to the foot section 8, is in the Figures 18 and 19 As can be seen from these figures, the foot part section 7 has two parallel beams 52 which are connected to one another by means of a cross beam 46.
  • the beams 42 carry the slats 43.
  • the foot section 7 equipped with tabs 44 which, in the final assembled state, interact with the associated tabs 41 of the foot part section 8.
  • the tabs 44 and 41 define, in the manner already described, the axis of rotation 10 around which the foot part sections 7 and 8 can be pivoted in relation to one another.
  • the spars 42 of the foot section 7 provide holes 45.
  • the foot section 7 is hinged to the extensions 33 and 34 through these holes 45 (cf. Fig. 15 ) of the outer frame 23. This enables the previously described rotational movement of the foot part section 7 about the rotation axis 9 defined by the extensions 33 and 34.
  • the cross member 46 of the foot section 7 has an abutment 67 in the form of a tab, as can be seen in particular from the illustration according to Fig. 18
  • a drive device 65 is connected to the abutment 87, as can be seen, for example, from the illustration according to Fig.7
  • the cross member 27 of the outer frame 24 provides an abutment 66, as can be seen from the illustration according to Fig.
  • a pivoting movement of the foot part section 7 can therefore take place by operating or activating the drive device 65 and thus also a pivoting movement of the foot part section 8, which is connected to the foot part section 7 in an articulated manner, wherein the foot part section 8 is coupled in terms of movement to the outer frame 23 at the other end via the coupling elements 69.
  • the foot part section 6 of the foot part 3 facing the head part 2 has a total of three slats, namely the slats 86, 76 and 82, as can be seen from the top view according to Fig. 14 results.
  • the slat 86 is firmly connected to the outer frame 23, for which purpose the outer frame 23 provides the holders 37 and 38, as can be seen in particular from the illustration according to Fig. 15 result.
  • the other slats 76 and 82 are arranged to be movable in relation to the outer frame 24, for which purpose the previously described U-profiles 36 are provided which are arranged on the longitudinal beams 30 and 31 of the inner frame 24.
  • the movable slats 76 and 82 are in the Figures 20 and 21 or 22 and 23 in detail.
  • the batten 76 is designed as a towing section 71 of the foot section 6.
  • This towing section 71 has two beam pieces 74 which are connected to one another by means of a common cross beam 75.
  • the batten 76 is provided opposite the cross beam 75 and is supported by the beam pieces 73.
  • the spar pieces 73 On their inner sides facing each other, the spar pieces 73 each have rollers 77 which, in the final assembled state, are inserted into the respective associated U-profiles 36.
  • the spar pieces 73 each also carry driving pins 78.
  • the second movable bar 82 is in the Figures 22 and 23 It is designed as a towing section 72 of the foot part section 6.
  • the towing section 72 also has two spar pieces 79 and 80, which are connected to one another by means of a common cross spar 81.
  • the two spar pieces 79 and 80 carry the batten 82 on the upper side.
  • each spar piece 79 or 80 is equipped with rollers 83, which are accommodated in the associated U-profile 36 in the final assembled state.
  • the towing section 72 also has driver tabs 84 mounted on the beam side, each of which provides an elongated hole 85.
  • driver tabs 84 mounted on the beam side, each of which provides an elongated hole 85.
  • a driver pin 78 of the adjacent movable slat 76 passes through an elongated hole 35 provided by a driver tab 84. In this way, the two slidably mounted slats 76 and 82 are positively coupled to one another.
  • the movable bar 82 is in the manner already described in the final assembled state with its crossbar 81 between the driving pins 87 and 88 of the head part 2 arranged so that a movement of the head part 2 is transmitted to the movable slat 82. Since the slat 76 is positively coupled to the slat 82 in the manner described above, a head part movement leads to the two slats 82 and 76 being moved along with it. Due to the distance between the head part-side driver pins 87 and 88 on the one hand and due to the elongated hole design of the elongated hole 85 on the other hand, a delayed driver movement occurs between the head part 2 and the slat 82 or between the slat 82 and 76.
  • FIGS 7 and 8th show the slatted frame 1 according to the invention in its initial position.
  • the head part 2 is not pivoted and is immediately adjacent to the foot part 3, i.e. the distance between the foot part section 6 of the foot part 3 and the head part 2 is minimal.
  • FIGs 9 and 10 show a second position of the slatted frame 1 according to the invention. According to this position, the head part 2 is moved exclusively in a translational manner in relation to the foot part 3, and specifically away from it, so that a spacing is established between the head part 2 and the foot part 3. This spacing is in Fig.9 marked with "A".
  • the drive device 63 is used for the position shown. This is supported on the one hand on the frame 22 and on the other hand on the carriage 56, so that when the carriage 56 moves in relation to the frame 22, the head part 2 carried by the carriage 56 is moved translationally.
  • the Figures 11 and 12 reveal a third position of the head part 2. According to this position, the head part 2 is rotated in relation to the foot part 3, specifically about the axis of rotation 5. This rotational movement is accomplished by means of the drive device 55, which is arranged between the carriage 56 and the head part 2.
  • an angled transition is formed between the foot section 3 and the head section 2, which leads to an unwanted crushing of a mattress supported by the slatted frame 1 in this area.
  • an automatic mattress compensation is provided, which is achieved by the head section 2 not only pivoting about the axis of rotation 5, but also moving translationally in the longitudinal direction 4, away from the foot section 3.
  • the distance of the translational movement of the head section 2 depends on the angle of rotation. The further the head section 2 pivots in relation to the foot section 3, the further the head section 2 is moved translationally away from the foot section 3.
  • Fig. 11 shows a position of the slatted frame 1, according to which the slat 82 adjacent to the headboard 2 has already moved forward, but the other slat 76 is still in its starting position. In this position, a gap "B" is formed between the footboard section 6 and the headboard 2.
  • FIGS. 13 and 14 show the slatted frame 1 in a fourth position, according to which the head part 2 is fully upright, i.e. pivoted upwards as far as possible around the axis of rotation 5.
  • the head part 2 is not only twisted, but also moved away from the foot part 3 in translation to such an extent that the second slat 76 is also dragged along in translation and is at its maximum distance from the fixed slat 86, as in Fig. 14
  • a gap dimension "C" is created between head section 2 and foot section 6.
