Description

Bed conversion with equipment rack

The invention relates to a bed conversion with device carriers attached to one or both longitudinal parts, which are fixed to the longitudinal part of the bed conversion, but can be displaced horizontally thereon and can be removed therefrom. The devices required in each case for the user of the bed are in turn attached to the device support by means of eyelets, pins or other known constructions.

For many users of beds it is necessary to provide additional devices which can be brought as close as possible to the user, adapted to the respective sitting or lying position of the user and easily brought into the required position by the user or third parties. This applies in particular to hospital beds in clinics, beds for people with restricted mobility, but also to other bed users. Devices of this type are, for example, table tops, box elements such as bedside cabinets, etc., instrument carriers, support rods for sick beds, which serve to raise limbs and / or to help the patient straighten up. In the known beds, in particular also in the hospital beds and beds for old people's homes, it is ^' usual throughout to provide the respective additional devices separately. In the hospital area, table tops and bedside cabinets, if necessary in combination, are provided with castors and each pushed to the bedside. The same applies to other device carriers, such as infusion devices. Carrying poles for lifting limbs or as an aid in the erection of patients are usually fixed to the head or foot of the bed, but can be removed. In the area of furnishing dormitories and private apartments, bedside cabinets and table tops for beds are also not equipped with castors and, if not immobile at all, are connected to the beds as a unit, only to be lifted or moved to other positions desired by the user. wear. With the exception of table tops for patient beds, in which an adjustment in the vertical or horizontal direction is known, the mentioned additional devices cannot be adjusted in the inclination of the respective position of the user of the bed.

The object of the present invention is to avoid the disadvantages of known constructions described above. This task is essentially solved by

that an equipment carrier is attached to at least one longitudinal part of the bed conversion according to the invention, which is horizontally displaceable in the manner of a slide over the entire length of the longitudinal part of the bed conversion;

P or in the lower area of the device carrier connect this to the longitudinal part by means of a releasable locking device and the device carrier device can be removed after releasing the locking device.

The bed conversion according to the invention with equipment carrier consists of the bed conversion 1 and the equipment carrier 7, 7 ', 7' *, 7 ' ^{, r} . The bed conversion 1 consists of the foot part 2, the head part 3 and the two longitudinal parts 4. In an expedient embodiment, the longitudinal parts 4 are firmly but releasably connected to them at least on the head part or on the foot part by means of hanging fittings 6 known per se.

In the illustrated embodiment, a support frame 5 is schematically shown, which is part of the actual bed and to which the bed conversion 1 is in turn known in a known manner by screwing or releasable connections such as hanging fittings.

According to the invention, a device carrier 7, 7 ', 7 *' or 7 ' ¹ ' is attached to at least one of the longitudinal parts 4, which comprises the longitudinal part 4 in the manner of a slide and on it in the horizontal direction over the entire length, <? Gf «too is slidable only over part of the length of the longitudinal part. In its respective embodiment, the device carrier is adapted to the longitudinal part 4 of the bed conversion in such a way that it can be easily moved thereon, but is connected to it in a stable manner and can neither protrude from the longitudinal part 4 in the longitudinal direction nor laterally.

In the embodiment according to FIG. 3, the longitudinal part 4 is convexly rounded at the top and bottom. The device carrier 7 u - on the side facing away from the bed, the longitudinal part 4 in its entire height and overlaps the upper and lower width of the longitudinal part, being in the upper

OMPI and the lower area is concave and the rounding of the longitudinal part 4 is adapted. In the upper area, the equipment carrier 7 has running rollers 8 and 9 on the inside with concave running surfaces, the shape of which is also adapted to the curvature of the longitudinal part 4 and lies on the longitudinal part. In the lower area, the equipment carrier 7 also has the roller 10, which is likewise fitted on the inside, with the same design as the rollers 8 and 9, which engages in the longitudinal part 4 from below. In the sense of the invention, however, this lower roller 10 can also be dispensed with.

The device carrier 7 has the semicircular hole row 11 in the upper area for receiving the additional devices and the counter pin 12 in the lower area. The additional device required in each case is in the pin 12 and depending on the required inclination of the additional device in one of the holes in the hole row 11 used.

In the embodiment according to FIGS. 4 and 5, the longitudinal part 4 * has the concave grooves 16 and 17 instead of the semicircular shape on the top and bottom. The device carrier 7 'is designed like the device carrier 7 according to FIG. 3, but has on the inside on the top the two ball rollers 13 and 14 which run in the raceway 16, and in the lower region the ball roller 15 which in FIG the groove 17 engages. To accommodate the additional devices, the device carrier can also have the row of holes 11 and the pin 12 in this embodiment as in the embodiment according to FIG. 3. In FIG. 5, as a further fastening device for the accessories, which can be used for all embodiments of the device carrier, one or preferably also in the upper region in the upper area instead of one roller 28 several and only one roller in the lower area.

The equipment carrier 7, 7 ', 7 ", 7"' can if necessary after removing the longitudinal part 4, 4 ', 4'',4'^"1 from the head part or foot part of the bed conversion according to the invention or by means of an adjustable locking device of the above running and / or the roles of the equipment carrier running below. If necessary, instead of several equipment carriers, it can also be attached to a longitudinal part.

The equipment carrier can be provided with an eccentric or "clamping lever or with another locking device to secure against unintentional displacement on the longitudinal part.

The bed conversion according to the invention with equipment carrier offers the following advantages over the known beds and additional devices:

In contrast to the known designs, it enables the additional devices to be attached directly to the respective bed. On the one hand, this saves space and prevents disabilities caused by devices with foot frames or castor frames that are set up separately next to the bed. Furthermore, a more precise arrangement of the additional device required in each case is made possible for the user of the bed. Due to the construction of the device carrier as a slide, especially in the illustrated embodiments, the device carrier can be moved on the longitudinal part of the bed conversion with only very little effort, so that it can also be used physically several pins 18 are provided. In the embodiment according to FIGS. 6 and 7, the longitudinal part 4 * 'is a continuous casting profile which has on its top and underside the tunnel-tubular profiles 19 and 20, which in turn extends to the outside of the longitudinal part 4''in the longitudinal direction are open, but otherwise have the convex shape as in Fig. 3. The device carrier 7 ″ includes the longitudinal part 4 **, just like the device carrier 7 in FIG. 3. However, in the upper area it has the internally guided ball roller 13 and in the lower area the ball rollers 23 and 24, which are located between the upper level 21 and the lower level 22 of the box profile and the profiles 19 and 20 run. In this embodiment, the profiles 19 and 20 of the longitudinal part 4 '' accordingly slide between the upper and lower circular part of the device carrier 7 '' and the rollers 13, 23 and 24 attached therein. In the sense of the invention, the rollers can also be used this embodiment as in the embodiments 7 and 7 "of the device carrier, ie two in the upper area and one or more in the lower area.

8, as a further embodiment, the longitudinal part 4 '''is provided on the inside in the longitudinal direction with an upper guide groove 25 and a lower guide groove 26. The device carrier 7 ^'11 comprises the longitudinal part 4''' from the outside and extends over the width of the guide grooves 25 and 26. The roller 28 is attached to the overlapping part of the device carrier 7 '''in the upper region that runs in the guide groove 25. The rollers 29 and 30, which run in the guide groove 26, are attached to the lower region. Here, too, the essence of the invention is not affected by the fact that

OMPI weakened bed users are able to operate their own; this has particular advantages when the invention is used for sick beds, because the patient can himself bring the respective additional devices into the position that is best for him when changing his position. Irrespective of these advantages, the design of the device carrier according to the invention and its adaptation to the longitudinal part of the bed conversion according to the invention ensure greater stability of the additional devices attached to it and the risk of accidental displacement, which is known, for example, from device carriers for hospital beds excluded by overlooking the foot or roller frames.

In contrast to known additional devices for beds, the bed conversion according to the invention with equipment carrier also makes it possible to adjust the horizontal inclination of the respective level of the bed, e.g. with sloping lying surfaces of hospital beds in hospitals. The bed conversion according to the invention with equipment carrier also allows the simultaneous attachment of two or even additional equipment carriers to a bed, both in the form of attachment to a longitudinal part and in the form of attachment to both longitudinal parts of the bed conversion; this offers a considerable advantage in terms of space saving and correct arrangement of the additional devices compared to the user of the bed.

Another advantage of the bed conversion according to the invention with equipment carrier is that the equipment carrier can remain on the bed or bed conversion without hindrance to the user and / or third parties, such as nursing staff, when the additional devices have been removed. Conversely The ready attachment for the additional devices ensures immediate readiness for use.

As mentioned above, however, the device carrier according to the invention can also be removed from the longitudinal part. This offers the advantage that a bed with the bed conversion according to the invention can be used as a normal bed without the device carrier attached, but if necessary can be equipped with the device carrier without replacing the bed.

So it is e.g. It is possible to use the bed conversion according to the invention for a normal bed in old people's apartments, but also to use the same bed conversion for a sick bed if the bed user becomes a case of care.

Finally, the bed conversion with equipment carrier has aesthetic advantages because, in contrast to the combination of a bed with additional devices, it brings about a formal unity in the known manner, and, as mentioned, the use of formally mostly unsuccessful separate accessories or racks unnecessary for this.
