Definitions

  • Bed in particular hospital or nursing bed
  • the invention relates to a bed, which is in particular a hospital bed or a nursing bed.
  • Such beds generally have a base which rests on a base and is provided with foot or stand elements. Above the base frame is the top frame with a bed frame, which consists of a head part, a foot part and two side frame parts connecting them. Inside the bed frame is a mattress support device, which in the simplest case is a rigid, flat plate or a slatted frame.
  • Sick or nursing beds are generally height-adjustable by motor and mostly have motor-adjustable mattress support devices.
  • several motors are attached to the bed frame (base frame and top frame), which use various gears to move lifting and lifting elements for the height adjustment and adjustment arms for the mattress support device.
  • the drive motors including the gears in closed housings.
  • the motors and the gears are housed in m housings (mostly made of plastic).
  • Rotatable axes protrude laterally from the connecting part, on which pivoted levers are attached to the mattress support device and the base frame.
  • the connecting part with its U-profiles thus represents a housing surrounding the drives, which has no structural function for the overall construction of the bed.
  • the known bed construction is relatively complex and large in volume in relation to the connecting part.
  • a sturdy construction that can only be carried out with great effort must be chosen as the underframe, since the connecting part for lowering the mattress support device swings or dips into the underframe into a position that is comfortable for lying down in and getting out of the bed.
  • the frame structure of the underframe which is open at the top, does not give it sufficient stability when raised.
  • DE-U-17 18 671 describes a bed which, for the purpose of privacy and glare protection for the person lying in bed, has shielding plates on the long sides of the bed which, when not in use, below the mattress cushions can be stowed away. How the extension movement mechanics of these shielding plates is carried out is not specified.
  • the invention has for its object to provide a bed, in particular hospital or nursing bed, which has a simple and therefore inexpensive to implement stable construction, which is designed such that the bed is clearly structured and organized according to functional groups.
  • the invention proposes a bed, in particular a hospital or nursing bed, which is provided with a base frame which has at least one foot or stand element for supporting on a base, an upper frame connected to the base frame and having a head part and having a foot part, and a mattress support device for supporting a mattress having a lying surface, the mattress support device being arranged between the head and foot parts of the upper frame and having at least one movable mattress support part which is adjustable by means of at least one adjustment arm which can be moved by an adjustment drive device is.
  • the mattress support device is held by the hollow profile support, the at least one adjustment arm of the at least one adjustable mattress support part being movably mounted on the hollow profile support, that the base frame is connected to the hollow profile support, that the at least one adjustment drive device is at least partially outside of the hollow profile carrier is arranged and that the parts of the at least one adjustment drive device arranged outside the hollow profile carrier are covered by a cover hood detachably attached to the hollow profile carrier.
  • the upper frame of the bed according to the invention is provided with a centrally arranged profile carrier, at the opposite ends of which the head part and the foot part of the bed are preferably attached.
  • the profile beam extends along the central longitudinal axis of the bed, which is why the head part and the foot part protrude equally over the long sides of the profile beam.
  • the profile carrier itself is arranged below the mattress support device and has an upper side facing the mattress support device. This upper side is sealed at least in some areas or is designed as a closed wall.
  • the profile carrier is the only connection arranged in the center of the bed between the underframe and the mattress support device.
  • the profile carrier is connected to each of these two assemblies of the bed.
  • the profile beam is therefore of structural importance in that it supports the stability of the connection both to the base and also provides for the mattress support device and supports the head and foot sections.
  • the profile carrier is thus the central structural element of the bed according to the invention, to which all assemblies and units are attached.
  • the profile carrier should have maximum stability and, in particular, torsional stiffness, as lightweight and flat as possible, which can preferably be achieved with a one-piece (flat) square hollow profile carrier.
  • the novel construction of the bed according to the invention with a central profile beam, in particular a hollow profile beam (hereinafter also referred to as a central beam) is particularly advantageous if the bed has a height adjustment and / or a mattress support adjustment.
  • a central profile carrier specifically below that or those regions of the profile carrier in which the latter has a closed upper side (cover sections).
  • the entire adjustment mechanism and drive technology can thus be arranged and stored clearly and concentrated on the center bracket.
  • the profile carrier also receives the control units, the energy supply units (accumulators or the like) and the entire cable routing.
  • a "profile support” is a structurally effective support element which is formed in one piece (in particular as an extruded profile) or is composed of several parts.
  • the carrier element has a hollow profile.
  • the drive motors are preferably accommodated in closed foot or stand elements arranged on the top and bottom sides, in particular with rollers, which have closed housings, from which only the lifting elements, which are designed as extendable stamps, project upwards for lifting the central support.
  • Lifting elements which can be extended in the direction of the upper frame or retractable in the direction of the lower frame have the advantage of simpler construction and ease of cleaning and ease of use compared to lever structures such as are numerous in the prior art.
  • lifting frames are preferable to lever frames as a realization for the bed base frame.
  • the accommodation of the drive mechanism for, for example, the mattress support device underneath the upper side of the profile support, which is closed towards the mattress support, has further advantages in that the individual drive motors do not have to have any encapsulation or housing that is in particular watertight. Rather, the profile carrier, together with the cover that can be attached to it from below, serves as a housing for protection against injuries and splashing water, as well as cleaning agents.
  • the profile carrier is designed as an extruded part with, in particular, a square profile. All the drive elements and driven elements for the mattress support device and, if necessary, the height adjustment can now be accommodated within the space delimited by this profile support and below the hollow profile support.
  • the profile beam as a further alternative, it can be designed in the form of a U-shaped beam which is open at the bottom and is closed by a cover. In order to be able to use profile girders with flatter cross sections, it is expedient to have the drive motors and possibly the adjusting levers protrude from the girder through recesses in the underside thereof.
  • These functional recesses in the hollow profile carrier are particularly and preferably exclusively formed in the central section of the hollow profile carrier when viewed in the longitudinal direction, where it extends between the pairs of lifting elements of the height adjustment of the bed arranged on the head and foot sides.
  • This has the advantage that the bed can be lowered relatively far, since the central support in its end sections projecting from the central section on both sides, in which it is connected to the foot or stand elements of the base frame, is flat, so that the mattress support device in the the most downward lowered state of the bed runs directly above the foot or stand elements of the underframe.
  • the adjustment arms for pivoting the individual mattress support parts of a multi-part adjustable mattress support device advantageously protrude to the long side or to the underside of the profile or central support.
  • the adjustment arms are expediently mounted on swivel axes which protrude from the longitudinal sides of the profile or central support and from which the adjustment arms protrude radially.
  • two such adjustment arms are provided, which are located on both sides of the central support can be pivoted in each case in vertical planes arranged near the central support.
  • the central support also carries the head and foot sections. These two parts are attached to the front ends of the center beam.
  • the foot part alternatively or additionally, but also the head part
  • the respective part should be lockable in the individual pull-out positions.
  • the head or foot section can be moved by a motor.
  • control unit for the nursing staff is provided on the bed, it is advantageous if this control unit is arranged in alignment with the center support, for example on the foot part. This has the advantage that all of the lines originating from the operating unit can be guided and held directly on the central support in order to run to the control unit or to the individual drive motors.
  • a hospital bed or nursing bed has so-called safety side parts, which are arranged on the side of the mattress support device and can be moved into a position in which they protrude upwards over the mattress support device and a mattress lying thereon.
  • safety side parts In order to transfer the safety side parts into a position below the mattress support device or the mattress so that the patient can comfortably get out of bed, folding mechanisms and swivel mechanisms have been proposed in the prior art.
  • the security side panels are parallel to Extent of the head and foot section pivoting pivot axes, the safety side parts can be pivoted to below the mattress pad. In this position, however, they hinder free access to the area of the bed below the mattress pad.
  • the safety side parts are slidably mounted on the hollow profile support or the mattress support device in order to be able to be extended laterally beyond the mattress support device.
  • the safety side part can be moved more or less laterally beyond the mattress support device without it folding down in this state. Thanks to this pull-out mechanism, the safety side parts can also be used as additional storage space and as a widening of the mattress support surface. Both are advantageous, on the one hand for the nursing staff, in order to create additional parking space required when caring for the patient or, for example, in the case of a stroke patient to create a wider resting and support area to the side of the upper body.
  • the safety side parts When the maximum pull-out position is reached, the safety side parts can be swiveled up into a raised position, in which they lock themselves. In this raised position, the safety side parts are then used for lateral securing on the side edges of the mattress support device.
  • the arrangement of the safety side parts on the mattress support device itself has advantages, in particular in mattress support devices with a pivotable upper body part, since the safety side part is then moved when adjusting this mattress support part, so the entire height of the safety side part is available in any inclined position of the relevant mattress support part. In the lower foot area of the bed it is not necessary (but it can also be an advantage) to store the safety side part on the mattress support device so that it can be moved when it is pivoted. It is sufficient here if the safety side part is mounted on the central support.
  • the safety side parts look like the side parts of a bed frame.
  • the safety side parts can be formed on their sections running along the edge of the mattress support device with profile bodies, in particular of elastic plastic material. In this way, a ram protection is provided which reduces the risk of damage to door frames, for example, when moving the bed.
  • the profile body can also just as well consist of wood, for example, which will be encountered in particular if the bed is made of wood panels or the like, for example, on the head and foot part. has wooden cladding or construction elements.
  • the side parts can be changed in length.
  • a strut forming the upper end of the side parts is arranged displaceably on the side part. This displaceability takes place in particular in the manner of a telescope.
  • the strut should be lockable in its individual pull-out positions on the side part.
  • FIG. 1 is a perspective view of a bed according to a preferred embodiment of the invention.
  • FIG. 2 shows a top view of the bed according to FIG. 1 without a mattress and with a mattress topper indicated by dash-dotted lines,
  • Fig. 4 is a section along the line IV-IV of Fig. 2 and
