Description

Folding siderail, especially for hospital beds

Technical field

The invention relates to a tilting siderail, in particular for hospital beds, comprising two side pillars pivotally connected at the bottom by pivots to the bed frame, wherein at least two bars are articulated between the side pillars and at least one of the side pillars is provided with a detent mechanism.

BACKGROUND OF THE INVENTION

Hospital beds are very often provided with siderails to prevent accidental fall of the patient, blanket, etc. At the same time, however, the siderails must be foldable or removable so that the patient can easily leave the bed or the nursing staff have free access to the patient.

The current trend is to use mattresses of greater thickness (120 mm or more) or active anti-decubitus mattresses whose thickness starts at 200 mm. Therefore, siderails that are as high as possible in the upright position are required.

The folded side panels should be as low as possible under the bed surface, but at the same time they should occupy as little space as possible on the side of the bed when many accessories are hung.

The known folding siderail for hospital beds has two side pillars, pivotally connected at the bottom by pivots to the bed frame. At least one of the side posts is provided with a locking mechanism for fixing the siderail in an upright position. At least two bars are articulated between the side pillars so that the entire siderail is a so-called multi-hinged para20 lelogram. All sidereal joints lie essentially in one plane, namely in the folding plane.

A disadvantage of such a construction is that the lower of the bars that connect the side pillars, when the siderail is lowered, abuts the pin of one of the side pillars, so that the siderail cannot be lowered below. If the known siderail is raised to provide sufficient protection even for beds with a high mattress, in the lowered state, the upper rod of such an elevated siderail protrudes above the mattress surface, which is unacceptable from the point of view of patient comfort.

The essence of the technical solution

These drawbacks are remedied by a folding siderail, particularly for hospital beds, which comprises two side pillars pivotally connected at the bottom by pivots to the bed frame, wherein at least two bars are articulated between the side pillars and at least one of the side pillars is provided with a locking mechanism , according to a technical solution which is characterized in that at least the pin to which the bars are tilted is arranged outside the plane of tilting.

An advantage of the foldable siderail according to the invention is that the lower of the bars that connect the side pillars can pass the pivot when the siderail is tilted without coming into contact with it. Thus, the siderails of the present invention may be higher than the prior art siderails in an upright position, and yet in their folded position their upper edge does not extend above the bed mattress.

According to a preferred embodiment, the pin to which the bars are folded is arranged below the bed surface of the bed and the respective side pillar is spatially bent towards the pin at the lower part.

BRIEF DESCRIPTION OF THE DRAWINGS

The folding siderail for hospital beds according to the invention will be described in more detail by way of example of a specific embodiment, shown in the attached drawings, in which the individual figures show:

Fig. 1 is a hospital bed with a siderail in an upright position;

Fig. 2 is the same hospital bed with the siderail in the lowered position, Fig. 3 is a detail of the siderail of Fig. 2, and Fig. 4 is a bottom view of the hospital bed with the siderail.

Examples

1 and 2 show a hospital bed with a hinged siderail according to the invention. The hinged siderail has two side posts 1, 2, connected in the lower part rotatably by means of pins 3, 4 to the bed frame 5. Between the side columns 1, 2, four bars 6 are arranged one above the other, which are articulated on both sides to the side columns I, 2. The entire siderail thus forms a so-called multi-articulated parallelogram.

At least the pin 3 to which the bars 6 are tilted is arranged below the bed surface 8 and therefore lies outside the plane of the tilting (see FIG. 4). The respective side pillar 1 is spatially curved towards this pin 3 at the bottom. In the embodiment of FIGS. 1 and 2, both pins 3, 4 are arranged below the bed surface 8 of the bed.

In order to keep the siderail in the upright position, at least one of the side columns 1, 2 is provided with an actuating mechanism 7. An example of an embodiment of a simple locking mechanism 7 can be seen in Fig. 3. A collar is fixedly connected to the side column 1, in which a locking pawl 9 is slidably mounted, which is pressed against the locking plate 11 by a spring (not shown).

Fig. 1 shows a hospital bed with a siderail in an upright position. If the siderail is to be lowered to the lowered position, the latch 9 must first be manually pulled out of the detent opening 10 and the siderail can be folded down. Since the pin 3 to which the bars 6 are tilted is arranged below the bed surface 8 and therefore lies outside the plane of the tilting, the lower bars 6 can be tilted lower than the joints of the pins 3,4.

During the erection of the siderail, the detent bolt 9 slides on the detent plate 11 until it reaches the detent opening 10 into which the spring (not shown by pressure), engages and thereby fixes the entire siderail in an upright position.

Claims (2)
