DE202006004883U1 - Hospital bed, comprising length adjusting mechanism working with gas pressurized spring - Google Patents

Abstract

The bed comprises a frame (12) with height adjustable legs and rollers for being moved if required. The sleeping area can be adjusted regarding its length. It is assembled of two units, each with a head- (2), a foot board (1), respectively, and telescopically arranged lateral elements (4, 11). The piston rod of a gas pressurized spring is joined to the frame part at the foot end. When a button (13), located at the foot board (1) is pressed the spring is released and the frame part moved into the appropriate position.

Description

The The invention relates to a variable-length Hospital or nursing bed according to the preamble of the claim 1.

Such Hospital or care beds - simplicity In the following, only the bedside will be referred to - this is how it is designed that her mattress frame renewable is, so for example, a correspondingly larger-sized mattress can be inserted.

there is the foot and head-side bed main supporting mattress frame formed in two parts and consists of an extension part and a frame part.

While that Frame part usually height adjustable connected to a rack frame, is the extension part guided telescopically in the frame part, that is, the extension part becomes an extension of the mattress frame pulled out of the frame part.

At least in the respective end positions, i.e. in retracted or extended Position is the extension part across from the frame part lockable, including, for example, provided manually operated catch could be.

The Pulling out the extension part to Magnification of the lying area or for extension of the mattress frame done manually. However, this is a corresponding effort necessary, which complicates the handling of the hospital bed as a whole, wherein the frictional resistances to be overcome resulting from the contacting leadership extension part in the frame part, contribute to a difficult pulling out.

Everything in everything leaves the well-known hospital bed in terms of ease of use wishes.

Of the Invention is the object of a hospital or nursing bed of the generic type to develop so that it in particular at the extension the lying area is more manageable.

These Task is by a hospital or nursing bed with the characteristics of claim 1.

By this structural design of the hospital bed will be essential easier handling, especially when extending the lying surface frame achieved because of the energy storage, the extension part practically automatically from the Frame part is pushed out into a predetermined end position. A physical applied force of the operator, usually a nurse or a nurse, is no longer necessary, which naturally makes work easier entails.

To An idea of the invention, the energy storage as a compression spring be formed, preferably in the form of a gas spring or a coil spring.

at Use of a coil spring is a lock in the two End positions, i. in so-called "normal position" and "extension position" by means of a locking device, preferably in the form of a catch, the on a guide tube the frame part can be fixed and with corresponding locking openings a telescopic handle of the extension part corresponds, in the guide tube of the frame part is guided axially displaceable.

One such snap comes expediently also used when a gas pressure spring as energy storage Use finds. Preferably, such a configuration is at There is a hospital bed which can be placed separately on each longitudinal side Has side rails.

in the Case, that continuous side rails, consisting of distance and height-adjustable Side rails that are variable in length at the bedheads attached, are part of the hospital bed, can use at a gas-pressure spring stepless length adjustment, wherein then the gas compression spring over a trigger actuated is.

A easy operation of the shutter is given if this is arranged in the area of the bed head is, usually the extension part the foot side Is assigned to the main bed.

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

One embodiment The invention will be described below with reference to the accompanying drawings.

It demonstrate:

1 an inventive nursing or nursing bed in a perspective side view

2 the hospital or nursing bed in one perspective top view

3 the hospital or nursing bed in an exploded view

4 a partial section of the hospital bed in a plan view

5 a longitudinal section through the partial section along the line VV in 4

6 a detail of the hospital or nursing bed in an exploded view

7 the detail after 6 in a perspective view.

In the 1 - 3 a length-adjustable hospital or nursing bed is shown, which is a provided with casters frame 12 has, at the height adjustable a lying surface frame 3 is attached, which at one end a foot-side bed head 1 and at the other end a headboard on the head 2 holds.

On the long sides of the hospital bed side rails 4 provided, each of variable-length side rails 11 that exist in the bedheads 1 . 2 are fixed.

The mattress frame 3 has one with the Gestelkahmen 12 connected frame part 6 and a telescopically slidably disposed therein extension part 5 on, which in the present embodiment foot-side bed head 1 wearing.

For telescopic storage of the extension part 5 This is with two parallel and distant telescoping spars 8th provided in guide tubes 7 of the frame part 6 are guided.

According to the invention, the extension part 5 via a power storage with the frame part 6 connected, in the embodiment of a gas-pressure spring 9 exists, on the one hand on the frame part 6 and on the other hand on the extension part 5 is attached.

For this purpose is a piston rod 18 ( 5 ), in a cylinder 19 is guided axially displaceable, by means of a screw 17 on a frame spar 16 of the foot-side bed head 1 attached. Here is the piston rod 18 fixed axially adjustable by means of the screw.

Like in the 5 can be seen further, is to the piston rod 18 a trigger at the end 13 connected, as in the 6 and 7 is particularly clear from one in the frame spar 16 held sleeve 21 and a pushbutton mounted axially displaceably therein 20 that exists with the piston rod 18 the gas pressure spring 9 corresponds.

When the shutter button is pressed 13 ie its push button 20 , becomes the gas compression spring 9 by pushing one in the piston rod 18 integrated release pin 22 unlocked, leaving the foot-side bed head 1 and thus the extension part 5 relative to the frame part 6 is moved either from a normal to an extension position or vice versa. In principle, a stepless adjustment is possible, depending on the position in which the release button is no longer pressed.

Alternatively, for locking the extension part 5 a flycatcher 10 be provided as he exemplifies in the 2 and 3 is shown. This known per se, spring-loaded catch 10 is on the two guide tubes 7 of the frame part 6 arranged and engages in the respective end position of the extension part 5 in corresponding not shown locking openings of the telescopic spars 8th one.

How the particular 3 shows very clearly, the bedheads 1 . 2 one infill each 14 on, with the infill 14 of the foot-side bed head 1 at the bottom with a recess 15 is provided, over which a free access to the trigger 13 is possible.

To a uniform displacement movement of the extension part 5 to reach is the gas spring 9 approximately in the middle of the mattress frame 3 arranged.
