Description

The invention relates to a bed, in particular a hospital and / or nursing bed, consisting of a bed frame and a bed frame Support frame, the bed frame being formed from longitudinal and cross members.

Generic beds are known from the prior art and are in used in practice among other things in the health and / or nursing sector. she serve the patient to provide a comfortable and, above all, a disease or to be able to take care of lying or sitting position in bed. To this Purpose generic beds also mostly have lifting devices for Raising and lowering the bed frame and additional adjustment options regarding the lying surface.

A generic bed is disclosed, for example, by CH-A-167 118. What is shown here a sick and / or nursing bed, which consists of a bed frame as well a lifting frame supporting the bed frame is formed. For lifting and A corresponding lifting device is provided to lower the bed frame enables the patient to move the bed frame relatively high in height. DE 44 16 689 discloses a bed, in particular a hospital bed, which consists of a bed frame and a height adjustable in the bed frame guided essay with bed frame is formed. This bed also has two independently operable drive motors that serve the To move the bed attachment in height. To ensure that at the Height adjustment of the bed attachment a certain position, especially one horizontal position, is maintained, it is proposed that the bed have a Horizontal control device for the bed attachment with one Tilt detection device for detecting the tilt of the bed attachment opposite the bed frame.

DE 195 47 206 C1 and EP 0 433 737 B1, for example, also disclose one hospital and / or nursing bed each with a bed frame and one Bed frame carrying support frame. Are over an appropriate lifting device the bed frame and the support frame are coupled to one another, the bed frame is movable in height relative to the support frame. In order not to look for additional To be instructed by staff is a height adjustment of the bed frame a remote control to be operated by the patient is possible.

Finally, DE 22 23 271 discloses a hospital bed with an upper part and a chassis, the upper part being liftable relative to the chassis and is lowerable. To improve lifting comfort and to avoid Disadvantages associated with the use of hydraulic jacks go hand in hand, it is proposed here that to raise and lower the A mechanical inclined plate device is provided, and that A hydraulic damping support is available to control the lowering.

Generic beds also usually have idlers that consist of both around their transverse as well as rotatable about their vertical axis casters are formed and a little effort to move and good maneuverability ensure the bed.

The commercially available hospital and / or nursing beds are of standard size or Standard dimensions designed. As a rule, they have a standard lying surface dimension from 90 x 200 cm. The usually available The lifting capacity of the lifting device is for a lifting weight of up to approx. 200 kg dimensioned. However, it is important to take into account that this is a total lifting weight to be moved by the lifting device from the weight of the Patient and the height-adjustable parts of the bed itself results. For this reason, the maximum permissible patient weight is mostly limited to about 130 to 140 kg, which also applies to the beds of the previous cited documents apply.

Particularly with regard to the possible lifting capacity of the lifting device Standard hospital and / or nursing beds for overweight people with Disadvantage not suitable. First, there is a risk that the bed construction does not withstand use by overweight people, for others cannot guarantee safe operation of the lifting device, as soon as a lifting force of over approx. 200 kg is required. It is also for overwhelming People often do not have the available lying area of 90 x 200 cm sufficient to allow comfortable lying.

To give even the heaviest people the opportunity to get sick and / or To take care beds into use, which have appropriate usage and Ease of use, such as the height adjustment or Lying surface adjustment, it requires special productions that are individually manufactured Need to become. This is disadvantageously very expensive.

The foregoing, the invention has for its object to provide a bed that is simple and economical to manufacture and is suitable for accommodating even heavy people.

To achieve this object, the invention proposes that the bed frame has additional load-bearing truss elements.

This measure provides a strengthened bed frame that is suitable for taking larger loads. In addition, the invention Bed frame resistant to twisting and bending.

With the bed according to the invention, a series production becomes economical for the first time manufacturable bed provided that can accommodate heavy loads is suitable, which also gives heavyweight people the opportunity will use hospital and / or nursing beds that are available via the common operating and comfort devices, such as lifting and Lying surface setting. Here is under heavy load in the sense of Invention to understand a body weight of up to 350 kg.

The bed according to the invention has a lifting device for lifting and Lowering the bed frame, which makes it possible compared to the state of the Technology to generate significantly higher lifting power, so that even when used of the permissible total weight under and under the bed frame Consideration of all security aspects is guaranteed. Also the Adjustment of the lying area is due to the use Heavyweight matched.

According to a feature of the invention, those on the bed frame are additional arranged load-bearing truss elements formed from square tubes Crossbars. These are welded to the bed frame and cause one Reinforcement of the bed frame, which has an overall higher load capacity allows. Alternatively, the cross braces with the bed frame can also be used be screwed.

According to a further feature of the invention, the bed frame has a Bed frame arranged on the bed frame, which over other additional Reinforcing elements in the form of reinforcing struts. These serve in addition, the bed frame frame consisting of bed frame supports and crossbar also to be reinforced in the manner of a truss. That too The support frame has an additional reinforcing bar. Just like that Cross struts of the bed frame are also the reinforcing struts of the Bed frame and the reinforcement bar of the support frame with the Overall construction welded, with other types of connection, such. B. screwing or gluing are possible.

The bed frame of the bed according to the invention has on its two end faces each on a bed frame, which are welded to the bed frame. Bed frame frames and bed frames together form the bed frame. The The bed frame has a support frame on the front edge. Any support frame for its part has a supporting beam carried by idlers, which has supporting legs aligned upwards. According to the support beam supplemented by a reinforcement bar. The supporting legs protrude upwards corresponding to the hollow bed frame supports of the Bed frame frame trained and in the ready-to-use condition of the pushed inventive bed into this. Each support frame has via a separate lifting device that connects the support frame to the respective associated bed frame frame couples. In this way, a Relative movement of the bed frame relative to the supporting frames can be achieved, by the bed frame supports guided by the support legs of the support frame the lifting device can be raised or lowered.

All bed components are designed or dimensioned so reinforced, that heavy loads of up to 350 kg are absorbed by the bed according to the invention can be. It is also possible to load such a heavy load both the lifting device for lifting and lowering the bed frame and the Adjustment device for leveling and aligning the lying surface is advantageous Ways can be used to optimize the lying position for those in bed to ensure the patient is there. For example, the Trendelenburg positioning.

According to a further feature of the invention, the bed frame is opposite each of the two support frames by means of a corresponding lifting device mechanical, electromechanical and / or hydraulic or pneumatic height-adjustable. For this purpose, each lifting device has one Lift motor. This advantageously generates a lifting force of 5000 N. Zur A corresponding supply of the lifting motor with electrical energy can Transformer may be provided.

The lifting device also has a pneumatic or hydraulic operable reciprocating piston. Alternatively, the lifting device can also be used a rack and pinion arrangement may be formed.

According to a particular advantage of the invention, the lifting motors are Lifting devices can be operated independently of one another, so that the bed frame can be moved individually by lifting and / or lowering each support frame is. In this way, an inclined to the floor can be Reach the position of the lying surface.

According to a further feature of the invention, the support frame has on the foot side Idlers. These idlers are advantageously from both around the Shaped casters mounted transversely as well as about the vertical axis can take a load capacity of at least 150 kg. For example each support frame have two support rollers, so that the invention Bed is provided with a total of four idlers, with a minimum load capacity of 600 kg is ensured.

The bed frame of the bed according to the invention is according to a further feature the invention with a lying surface reinforced by means of additional cross struts Mistake. This bed surface is by means of bed bed motors provided for this purpose adjustable. For this purpose, two are preferably connected in parallel Lying surface motors provided by a person lying in bed corresponding remote control can be controlled individually. That way the desired lying position exactly by adjusting the lying surface can be set. The lying surface motors preferably generate one Adjustment force of 10000 N.

According to a further feature of the invention, there is a mattress support provided, which is made of water-resistant multiplex plywood. The According to a further feature of the invention, laminated wood can have a metal internal reinforcement exhibit.

To secure what is in bed, you can also use the bed frame surrounding side rails can be provided. The side rail is preferably made of Wood formed with integrated metal internal reinforcement. For the The bed rail can also be used as a hospital version of the bed Steel side rails with plastic end pieces.

According to a further advantageous embodiment, this offers bed according to the invention has a larger lying area than the standard 90 x 200 cm, so that even an overweight person with a naturally larger one Space is given the opportunity to lie comfortably. It is also especially appropriate if additional side rails are arranged on the bed to prevent the person in bed from falling out. Without one the overweight patient would literally be narrower. It is therefore proposed to widen the lying area, for example 120 cm. To ensure that the bed can still be easily maneuvered it is also proposed that the additional lying surface on the standard lying surface with a width of 90 cm to arrange that this can be folded away if necessary, so that the bed is then a Standard width. It is e.g. possible, the beds according to the invention to be equipped from the outset with pivotable side areas, which the Widen the lying surface to, for example, 120 cm, the width if necessary the standard 90 cm can be reduced by folding away the side parts can.

According to a further advantageous embodiment, it is proposed according to the modular principle to a widening element in the desired width to arrange a bed of standard width. This can be done using, for example movable elements take place so that a folding away Widening elements is made possible. This can be done, for example, via simple Locking elements, hinges or similar respectively. Standard width beds can be used be equipped with arrangement devices in which the Widening elements can be hooked in, hung in or fastened in some other way can. This means beds for heavyweights with widened Lying surface is not specially stored and provided, but it is possible widen the beds to the required width if necessary.

It is also proposed to additionally support at least in the Connection area of the main lying surface with the widening element to arrange, which additionally supports the side part, so that an unwanted Breaking away of the side panel in the event of greater stress from the patient is prevented. Furthermore, can be folded down individually with the invention Lying surface, foot and headboard elements proposed. This will make the movements of the individual elements not possible via the lifting devices influenced and remain unaffected. Furthermore, the side parts should be like this be reinforced so that they meet the increased load requirements hold up by the heavyweight.

The fact that the lying surfaces can be folded down ensures that the Secured bed. One problem, particularly in clinical areas, is that Doors mostly have standard widths and the beds are matched to them in particular to the free transportation of the patient to his bed too to back up. Due to the advantageous design, the bed with foldable to provide widened side elements, which are either essentially permanently over hinges or similar attached to the standard lying surface can be added or subsequently via an alarm device if necessary be movably arranged on the bed and thus widen the lying area the overweight patient a comfortable lying area with sufficient Width provided, with the maneuverability of the widened Bed is not restricted, since the widening areas if necessary can be folded away, for example to drive through doors. there the side rails can be arranged on the widening elements.
