Description

The present invention relates to a lift bed, as it finds particular use in hospitals and nursing stations. Such elevators are often removed due to changing occupancy of space from the care rooms and stored.

The invention further relates to a double telescopic unit as to be used at the top or bottom of a lift bed component.

In lift beds of the prior art, the lying surface frame and / or the head, foot and side parts are regularly welded to the lifting columns, so that the intermediate storage requires undesirably much space.

Object of the present invention is to provide a pull-down bed and a double telescoping unit, in which the lying surface frame and the head, foot and side parts are easy to assemble and disassemble, so that it can be stored in a confined space.

According to the invention, the elevating bed consists of four telescopic lifting columns, which can be connected by a lying surface frame and head, foot and side parts, wherein the lifting columns each have in the direction of the adjacent side part an axis-parallel slot and the lying surface frame and the side parts corresponding anchor parts, the sliding from above in the slots are insertable.

To mount the elevating bed invention, the anchor parts are slidably inserted from above into the slots. The anchor parts of the bed frame are by suitable non-positive or positive means, such. Fixing or clamping screws, fixed in the slots of the lifting columns. The side parts can also be secured by suitable non-positive or positive fastening means, such as e.g. Locking or clamping means to be fixed in height adjustable in the slots. The side panels then form a backup, usually called side guard or grille, against falling out of a patient lying in bed.

Preferably, the lifting columns are each also provided in the direction of the adjacent head or foot with an axis-parallel slot and the head and foot with appropriate anchor parts which are slidably inserted from above into the slots.

In a preferred embodiment of the invention, the slots on undercuts, in which engage the anchor parts with corresponding elements.

In a preferred embodiment of the invention, the lifting columns are designed as spindle telescopes, wherein the upper telescopic section forms an outer, the slots or having sleeve.

The upper telescopic section can be formed as a continuous casting profile with integral, the slots receiving axis-parallel beads.

In particular, aluminum extruded profiles come into consideration, wherein, as with profiles made of other materials, the slots are integrally integrated into the profiles.

The spindle telescopes can be designed as two-stage or multi-stage, in particular three-stage telescopes.

The lifting columns form intrinsically stable spindle telescopes that meet the static requirements of the lifting columns of a lifting bed and do not require additional static parts, such as housing parts.

In a preferred embodiment of the invention, the lower inner sleeves of the head or foot receiving telescopic columns are on the bottom side, i. in its lower part, firmly connected by a bridge.

The two spindle telescopes connected by the bridge can be driven by a common electric motor, whereby the power transmission from the motor to the spindles takes place via toothed belts, chains or a shaft running inside the bridge.

As far as the side panels receiving slots are not covered by the side panels, plastic covers may be provided which engage in the slots or the end face of the open profile of the lifting column by clamping or latching.

According to the invention, from each two telescopic lifting columns a double telescopic unit can be created as a component for a lifting bed, wherein the two lifting columns on the bottom side, i. in their lower part, are firmly connected by a bridge and have means for fixing wheels.

The double telescopic units according to the invention form components for the top or bottom end of a lift bed in the embodiments described above. The lifting columns each have in the direction of the adjacent side part or in addition in the direction of the adjacent head or foot part Axially parallel slot into which the above-described anchor parts of the lying surface frame and the head, foot and side parts are slidably inserted from above.

The head or foot can be inserted in the respective slots or otherwise attached to the two lifting columns. The component can also exist without the relevant head or foot.

At or in the two lifting columns connecting bridge as an assembly, an electric motor can be arranged, which drives the two lifting columns. The power transmission from the motor to the lifting columns can be done via running inside the bridge timing belt, chains or a shaft.

Fig. 6

a perspective view of the elevating bed shown in Fig. 1 in the raised state.

Fig. 1 shows an inventive elevating bed 1 in a perspective view. The fold-down bed 1 consists of a head part 2, a foot part 3, and side parts 4, the can consist of several elements. The four corner posts of the bed are formed as telescopes 5, so that the bed can be brought from the low position shown in Fig. 1 in the high position shown in Fig. 6. Headboard 2, footboard 3 and the side panels 4 are interconnected by the outer upper telescopic sleeves 5.1. Each two of the telescopes 5, which delimit an end part (head or foot part) of the bed, are firmly connected to one another at the foot part of the inner telescoping sleeve 5.2 via a bridge 6. On the bridge of the electric drive motor 7 is arranged, whose axis protrudes into the bridge. The spindles of the two telescopes 5 are driven synchronously by means of toothed belt of the common motor.

The lying surface frame 8 has not shown in the drawing anchor parts, with which it is inserted from above into the slots 5.4 and 5.6 (see Fig .. 5) slidably. The slots 5.4 and 5.6 are closed at the bottom, so that the lying surface frame 8 rests in its lower position in the telescopes 5. For fixing the lying surface frame to the telescopes 5, not shown in the drawing clamping screws are provided, which are clamped with an abutment nut in the slots.

The lying surface frame 8 may have a lying surface integrally formed thereon, e.g. a rust, include. In another embodiment, it may comprise holding elements on which the lying surface, e.g. a rust, is held.

Bottom side, the telescopes 5 not shown in the drawing fastening means for wheels. At least two of the wheels can be designed to be lockable.

FIGS. 3 and 4 show further enlarged details X and Y from FIG. 1.

Fig. 5 shows an enlarged horizontal cross-section at the level of the circle "X" of Fig. 1. The telescopic sleeve 5.1 has two right angles arranged, molded beads 5.3 and 5.5, each having an undercut, axially extending over the length of the sleeve slot 5.4 and 5.6 have. Both the side parts 4 and the head or foot parts 2 include, as the already mentioned lying surface frame 8, on the lateral vertical end sides anchor parts 4.3 and 2.6, which are inserted into the slots 5.4 and 5.6. After inserting the anchor parts of the lying surface frame 8 and the front and side parts, the top of the telescopic sleeve with a snap-cap 9 (Fig. 2, detail A of FIG. 1) is covered.
