Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] An embodiment of the invention is explained below with reference to the drawings. In the drawings,

[0024] FIG. 1 shows a perspective view of an embodiment of a bed lifting frame with a lying surface in a lowered position;

[0025] FIG. 2a shows a first perspective view of the bed lifting frame of FIG. 1 in a raised position and a lying surface located in a sitting position;

[0026] FIG. 2b shows a second perspective view of the bed lifting frame of FIG. 1 in the position shown in FIG. 2a; and

[0027] FIG. 2c shows a side view of the bed lifting frame of FIG. 1 in the position shown in FIG. 2a.

DESCRIPTION OF THE EMBODIMENTS

[0028] An embodiment of a bed lifting frame according to the invention is shown in FIGS. 1 and 2a-2c. The bed lifting frame 1 includes a head unit 2 and a foot unit 3 which is arranged opposite the head unit 2, wherein the head unit 2 and the foot unit 3 form the head end and foot end of the bed lifting frame 1, respectively.

[0029] The head unit 2 comprises a head part 6, which is arranged in a height-adjustable manner on a first support unit 4 which stands on a floor. In order to adjust the height of the head part 6 relative to the first support unit 4, a drive unit 12 is arranged on the first support unit 4. The drive unit 12 allows for a motorized adjustment of the head part 6 relative to the first support unit 4, wherein a self-locking of the drive unit 12 ensures the adjusted height position.

[0030] The foot unit 3 is arranged opposite the head unit 2 and forms the foot end of the bed lifting frame 1. The foot unit 3 has two lifting columns 9 which are not directly connected to one another, so that between the lifting columns 9 there is a passage area 10 which allows free access to a lying surface 13. The lifting columns 9 each have a foot support 5, wherein the foot supports 5 together form a second support unit.

[0031] A column body 7 is arranged on each of the foot supports 5 and is adjustable in height relative to the foot supports 5, wherein drive units (not shown) are used here. Although the lifting columns can be adjusted in their height separately from one another by means of the separate drive units, a synchronous adjustment of the column bodies 7 relative to the foot supports 5 of the two lifting columns 9 can also be realized by means of a suitable coupling of the drive units.

[0032] The lifting columns 9 are connected to the head part 6 via two frame elements 8 which are arranged parallel and spaced apart from one another, and the two frame elements 8 form the longitudinal sides of the bed lifting frame. A lying surface 13, which has a total of three segments, namely a head/back segment 14, an upper leg segment 16, as well as a lower leg segment 15, is arranged on the frame elements. The three segments 14, 15, 16 can be pivoted relative to one another seperately via drive units 17 so that the lying surface 13 can be adjusted from the flat position shown in FIG. 1 to the sitting position shown in FIGS. 2a-2c in which the head/back segment is lifted up and the lower leg segment 15 is lowered relative to the essentially horizontally extending upper leg segment 16, so that the lying surface 13 overall assumes a chair-like shape. The height adjustment of the head unit 2 and foot unit 3 ensures that a sufficiently large area is provided below the lying surface 13 in order to adjust the lower leg segment 15 to the lowered position in FIGS. 2a-2c.

[0033] Longitudinal bars 18 are additionally arranged above the frame elements 8. In this case, the longitudinal bars 18 are mounted in a height-adjustable manner on the column body 7 as well as the head part 6, wherein the head part 6 has a correspondingly formed groove 19 for this purpose. For comfortable entering and standing up out of the bed lifting frame 1, retaining handles 11 are arranged on the upper sides of the column bodies 7, which in particular enables a user to comfortably stand up by holding the retaining handles 11.
