Description

Bed frame, in particular for hospital beds, a supporting device assigned to a frame part

The invention relates to a bed frame, in particular for a hospital bed, with an associated frame part Carrying device in the form of a so-called gallows, which has a base section running approximately parallel to the frame part as well as a boom head for lifting the load.

Especially for freshly operated or disabled patients such gallows are known which ¹ preferably on the head part of the bed frame are fixed. A mostly triangular handle hangs down from the oalgae head, which the patient can use to pull himself up. Such gallows are made from mounting brackets that run in the longitudinal axis of the bed frame and serve the purposes described.

A disadvantage \ i- Ii has υ both the .Pügi-lti η 1, exposed to the gallows described that the patient has difficulties to the bed edge swing canoe and outside the bedstead's help him ■ ra ^ ".- i *. · - ·: Gallows can no longer claim.

Given these circumstances hai · _; .;: i d ^ r Kr Γ i κ l <-r set the goal to better adapt the recognized disadvantages to the needs of the patient: and bed frames of the type mentioned at the beginning.

To solve this problem leads that the gallows relative to the frame of the bed frame rotatable and in preselected radial position of his head can be determined depending on the load. The gallows should move from an approximately parallel rest position to the frame part in a be designed inclined load position feasible.

Thanks to this hatred, the dalben according to the invention is no longer rigidly attached to the frame part - beforei'.ti-; t do: - Γο; T-frame of the bed frame - but can i :. its unloaded rest position around the axis of the stirrer · /.!-- gen base section until the gallows head has assumed a radial position that is suitable for the patient's wishes and is related to the pipe axis;, a "; ί. This radial position is then pulled into his load position by the suspended load of the patient, and Ir ₁ this is temporarily fixed.

When the load is removed, the gallows swings into its described position Rest position back, for which purpose it under the action of the restoring force stands, for example by Federele ^ enlf-.n is generated. liach a characteristic of Jer Erfl-.ir ■ ·; ! .τ ..: · '.;.

a simple Gurirr.i sleeve has proven to be particularly favorable, which are squeezed to the side when loaded and after being relieved is freed from this bruise.

Vw :. The training is of particular importance to the invention the radial locking elements provided on the gallows, which interact in the load position with an upright counter-detent. Of particular advantage here are two intermeshing and narrowly adjustable sprockets, vor- aeneti one protrudes from the gallows, while the other '!' .. ι! a; "support bearing of the bed frame -is; the tooth- ! nj de y an.
