Abstract

Raising bracket (5) fastened to a hospital or nursing bed (1) with a hanging device (7) arranged on a horizontally angled spar (6) and having at least one hook (12), characterized in that the hanging device (7) is detachably form-fitting. and / or is held frictionally on the spar (6).

Description

The invention relates to a mounted on a hospital or nursing bed Aufrichtbügel according to the preamble of claim 1.

Such Aufrichtbügel is used in addition to the attachment of a handle, for example in the form of a triangle on which a bedridden patient can sit up, the holder of containers with medically necessary content, such as infusion solutions, drugs or the like, which are attachable to hooks of a hanging device. This hanger is connected to an angled, horizontally oriented spar of Aufrichtbügels, which also carries said handle.

The attachment of the hanger is usually carried out by welding the hooks on the spar, so that they are an integral part of Aufrichtbügels. Naturally, this can only be achieved with a corresponding cost-intensive manufacturing effort.

In order to ensure a possibility of use of the hanging device in any case, it is necessary to attach the hooks on each Aufrichtbügel, which is used. That is, the hooks are also present when the hanger is not needed.

Notwithstanding the fixed installation of the hanger, it is known to attach the hooks on a cross-beam, which is connected via clamping screws on the spar.

Although in this case a need for attachment or removal of the hanging device is possible, but it must be prepared for loosening and tightening the clamping screws suitable tool whose use is otherwise possible only with a corresponding, often shy, effort.

The invention has for its object to develop a Aufrichtbügel the generic type so that its production is cheaper and its use easier.

This object is achieved by a Aufrichtbügel with the features of claim 1.

The invention now allows a particularly simple assembly and disassembly of the hanging device, which is possible without the aid of tools and thus represents a significant improvement over the prior art, which provides an attachment with clamping screws.

Even more so, the invention provides a simplification compared to welded on the spar hook and not only in terms of production, which is now much cheaper possible, but also in terms of usability.

Thus, the new hanger, as mentioned, easily and without tools to remove from a spar and at another, where it is needed, to install. That is, the erecting bar is made as a prefabricated part initially without hanging device and attached to the hospital or nursing bed. Only when needed, a separate hanging device is attached.

According to an advantageous embodiment of the invention, the hanger has a clamping bridge, with at least one U-shaped portal, which engages over the spar and which is provided on both legs, each with a movable in Aufsteckrichtung clamping element, which rest in the end position on the lower side region of the spar and clamp the hanging device in interaction with a formed insertion opening of the portal.

For this purpose, in this end position of the clear distance between the two opposing clamping elements is smaller than the associated dimension of the spar, usually the outer diameter. Preferably, the clamping elements are designed as pinch rollers whose axes of rotation extend parallel to the spar.

According to a further aspect of the invention, two opposing portals are provided, between which the two clamping elements are arranged and secured thereto. Via a connecting web, the two portals are connected to each other on the opposite side of the clamping elements, so that there is a compact unit.

In this case, at least one portal has at least one hook, but preferably two hooks are formed on each portal, specifically on the opposite side defined by a leg of the U-shaped portal.

A particularly cost-effective production of the holding device or the clamping bridge results when the portals with connected hooks and optionally the connecting web are integrally formed as a stamped part, wherein in each leg of the portals an arcuate guide rail is provided, in each case an associated pin of the pinch roller is guided movably in the vertical direction.

To ensure adequate clamping, the surface has each one Clamping element on a high coefficient of friction. For this purpose, the clamping element can be made entirely of a suitable material, such as rubber, plastic or the like, or with a corresponding coating.

In addition to the training as a stamped part, which then mainly consists of metal, in particular sheet metal, the clamping bridge can also be formed as a plastic molding.

Further advantageous embodiments of the invention are characterized in the subclaims.

An embodiment of the invention will be described below with reference to the accompanying drawings.

Show it:

1 a hospital or nursing bed provided with a Aufrichtbügel invention in a perspective view

2 the Aufrichtbügel according to the invention as a detail in an exploded view

3 the hanger of Aufrichtbügels as a detail, shown in perspective.

In the 1 is a movable hospital or nursing bed 1 shown with a headboard 2 a footboard 4 and a lying area 3 ,

At the headboard 2 is a righting bar 5 attached, the end to an angled, horizontally oriented spar 6 is shaped.

This spar 6 to which an unillustrated handle is fastened, carries a hanging device 7 in the 3 as a detail clearly visible.

In this case, the hanging device 7 a clamp bridge 8th , with two parallel and spaced apart U-shaped portals 9 on, passing through a connecting bridge 13 connected to each other.

For hanging in particular medical equipment or accessories is on every portal 9 , at the respective formed leg 11 associated side an open-top hook 12 formed.

Two thighs 11 of the respective portal 9 limit an insertion opening 16 for receiving the spar 6 who is at the bottom of this insertion opening 16 supported.

Parallel to the connecting bridge 13 running, are between the portals 9 on the thighs 11 two opposing clamping elements in the form of clamping rollers 10 connected.

These pinch rollers 10 are in, relative to the insertion opening 16 convex curved, approximately vertically extending guideways 14 led, including each pinch roller 10 frontally provided with a head guide pin 15 has, so that the respective pinch roller 10 axially secured, but is held movable in the vertical direction.

In the 3 is an end position of the pinch rollers 10 represented, which take them by gravity due to their own weight. Here is the clear distance between the opposing pinch rollers 10 smaller than the diameter of the spar formed as an oval tube 6 , while the clear distance in an upper, so to speak open, end position is greater than the horizontal diameter of the spar 6 ,

To the hanging device 7 at the spar 6 To attach, it is only placed from above on the spar, which is the two pinch rollers 10 in the direction of the connecting bridge 13 moved up, along the guideways 14 until it rests against the bottom of the insertion opening. In this position, the pinch rollers slide 10 due to weight in the guideways 14 in the lower end position, where they interact with the insertion opening of the portal 9 clamped on the spar 6 abut, so that the hanging device 7 held locked in any direction.

To release the hanging device 7 are only the pinch rollers 10 along the guideways 14 to push upwards, so that the hanging device 7 is free and can be removed.
