EP0092197A2 - Universal bed serving as a bedstaed fitting with an automatically adjustable mattress part without levers and pistons and with an integral patient lifting device - Google Patents

Abstract

The universal bed can be used as a bedstead fitting in commercially available bedsteads, the subdivided mattress permitting a stepless adjustment of the headrest, the back part and the upper and lower leg supports, without actuation of levers, motors or pistons. This invention concerns a novel bedstead fitting which, by means of its flat base part, can be fitted into any bedstead, and whose mattress frame, subdivided into individual elements, permits the stepless adjustment of the individual elements by inflating or deflating of air cushions. On the subdivided mattress frame (1) there is a subdivided mattress (M) which permits adjustment of inclination for the head element, the back element and the upper and lower leg supports by inflating or deflating the air cushions (K1), (K2) or (K3). The lifting device, connected rigidly to the bedstead fitting, with the column (8) and the lifting arm (11) makes it possible, by actuating the pump lever (13) to raise the bedridden patient on the lifting frame (15), which is connected tiltably to the lifting arm (11) by holding parts (16) and (16a) on the inclination holding device (14). By turning the column (8) with the tilting safety device (10) pulled out, the bedridden patient sitting in the lifting frame (15) is swung out to the edge of the bed, so that the lifting frame with the bedridden patient can be converted to a chair by lowering the lifting arm (11), and the leg support is brought into a sitting position by lowering the foot securing cords (16a) by actuation of the motor (17). After the sitting position has been adopted, the lifting frame (15) is dismantled by pulling out the frame tubes. Transferring the bedridden patient from the sitting position to the lying position takes place in reverse order.

Description

Universal deck provided with means for the stepless adjustment of the inclination of the head rest of the back part, the thigh and lower leg portion of a mattress, said Universal sun ettgestelleinsatz as _B for use in conventional bed frames or as an independent unit with fixed or folding legs as a multi-purpose bunk is used or with a Provide additional lifting equipment, for the care of bedridden people.

The invention is based on a combined lying construction, this with horizontally continuously adjustable adjustment devices for tilting the headrest, the support for back and leg parts is intended as a bed frame insert for use in conventional bed frames and is intended for home nursing with a vertically, pivotably arranged lifting device.

This universal bed as a combined bed frame insert for use in conventional bed frames of various designs and systems requires an absolutely flat or flat underside as a support surface.

Loungers whose mattress topper is divided and adjustable, but without the combination with a swiveling lifting device (lifts), are known in various forms.

The adjustment of the inclination of the lying surfaces is carried out particularly in the case of hospital beds with very expensive construction work such as mechanisms. Also known in the modern furniture industry, with the adjustment of the individual links being achieved by manually operated lever devices, actuation of a hydraulic system or by electromotive forces.

The levers and mechanisms required to accomplish this movement are complex and expensive to manufacture. Wear and susceptibility to failure. These known mechanisms for adjusting the inclination of the back part or the leg parts require, by design, to accommodate the mechanisms on the underside of the bed frame, these mechanisms often taking up a considerable amount of space and are not suitable for use as a bed frame insert with a required flat design.

Hydraulically operated adjustment devices are also known. An exemplary embodiment shows the patent specification OE 318 799 and the FRG Ausletschrift 22 18 171 for actuating a lever through a hose filled with liquid, the ends of which are provided with a sealing cap and use the pressure from the water line or the hydraulic pump.

Depending on the pressure of the liquid supplied, the bracket resting on the tube rises or falls in a rigid connection of the mattress part to be actuated. The disadvantage of this invention lies in the liquid pressure medium and the latent sealing problems, which means that there is always a risk of oil or water in the bed.

Air cushion 23 15 076 class 61 G 7/00 only uses an air cushion to increase the buttocks or to lengthen the thigh part of a mechanical adjustment device. The Federal Republic of Germany Auslegeschrift 24 08 784 class 61 G 7/04 is based on an invention, which has air cushions distributed underneath the entire mattress, which alternatively causes rocking movements for the bedridden to carry out a specific treatment method.

To adjust the inclination of individual members of the mattress pad of the present invention, on the other hand, a device has been created which eliminates the aforementioned disadvantages and also a completely flat underside as a bed frame insert allows for design reasons and also includes other advantages.

The mattress frame of this universal bed is divided into several links by joints and consists of a backrest, a seat part and an upper and lower leg support divided by a further joint, of which at least the backrest and the upper and lower leg support can be adjusted in inclination by the device according to the invention are, the mattress frame with a flexible fabric or spring net covering or with a resilient slatted frame serves as a mattress support, so that a sectional mattress divided according to the articulated members of the mattress frame also takes care of an anatomically correct lying position according to the respective link adjustment and inclination. This invention also enables an additional adjustment of the headrest solely by means of an additional link and air cushion. The subject invention uses pneumatics to adjust the inclination of parts of the mattress - however, without a lever or piston and without the associated linkage.

The only adjustment device used is a commercially available balloon air hose of a small motorcycle tire, folded over by half, mounted under the limb of the mattress pad to be adjusted, reaches twice the volume during ventilation and thereby enables an inclination adjustment of over 90 degrees. These folded hoses, which serve as air cushions, are ventilated by a hand or foot pump or by a small compressor used in DIY tools, the air supply and air evacuation of which was made possible by the operator using a specially developed control unit using the cheap hose valves that are also commercially available.

The valves can be opened manually - mechanically or manually - electromagnetically, with the latter switching the compressor being started at the same time. The small compressor with soundproof housing the size of a small shoe box, the connection cables of which lead to the control unit, can also be placed under the bed frame.

The combination according to the invention with a lifting device, this, connected to the lying construction as a unit, which enables the lifting (lifting) of the bedridden, is a component of the present invention.

The invention of the subject Universal sun without the combination with the lifting device but with fixed or folding legs, takes as _A llzweckliege for home and garden or beach use.

Taking into account the fact that bedridden people are released prematurely from clinical to home care for cost reasons and are often laboriously tied to the home bed, which usually does not meet anatomical requirements due to the lack of suitable home care, to a bed which has all the disadvantages compared to a constructive one has a well thought-out hospital bed, the present invention has been developed.

This universal couch according to the invention as a bed frame insert makes home nursing considerably easier, and offers the bedridden the opportunity to choose his most comfortable lying position day and night without an assistant.

The lifting device (lift device) integrated in this invention for effortless lifting (lifting) of the bedridden enables the bed to be cleaned, such as adding beds, changing linen, moving the person lying down into a sitting position, e.g. B. on a chair, all work that a helper could not do alone is now made effortless by this device without physical effort.

The lifting device (lifting device) for lifting or relocating the bed consists of a column, which is pivotally connected to a tilt-proof base, either on the head side or on the foot side of the bed frame. The lifting arm, also known as a gallows, mounted at a pivot point at the top of the column and running parallel to the longitudinal axis of the bed, extends up to about half the length of the bed and is provided with a slope compensation.

For easy lifting of the lifting arm, a hydraulic pump integrated in the column is used to construct a small car jack, which can be operated manually.

This hydraulic jack presses a lever which effortlessly lifts or lowers the lifting arm up to a weight of 150 kg via an operating rod.

To lift the bedridden, flexible straps are pushed under them, the eyes of which are hooked onto the lifting frame, which is hooked onto the support frame with integrated ropes to compensate for inclinations. During the lifting process, the bedridden person lies in a kind of stretcher from which he cannot fall out and does not feel any pressure points.

For moving the bedridden from the lying position to the sitting position, e.g. on a chair, only the auxiliary motor mounted on the support frame is put into operation by push-button control, which shortens the holding cables of the support frame on the head side and lengthens it on the foot side, to the extent that when the lifting arm is pivoted out, the foot side of the lifting frame touches the floor. Now you can comfortably slide a chair under the sloping bed.
