DE8217495U1 - DEVICE FOR INDEPENDENTLY ADJUSTING THE MATTRESS HEADBOARD AND THE MATTRESS FOOTBOARD OF A LIVING FURNITURE - Google Patents

Description

The invention relates to a device for the independent adjustment of the pivotable mattress head part and the swiveling mattress base part of a piece of furniture, consisting of a fixed to the frame Base plate on which two pivoted around a common axis, each with one of the Swivel arms that can be connected to mattress parts are articulated, from soft to one, with the mattress head part connectable swivel arm a latching support is articulated, the latches of which with a locking bolt fixed to the frame correspond, while the other, connectable to the mattress base swivel arm by means of a spring-loaded toggle lever is supported.

Such devices are widely known.

In the device of this type known from the German utility model 77 04 653, which is used in pairs Arrangement allows both an optional change in the inclination of the headboard, as well as the lifting of the

Supports the foot part and holds the latter in the open position, after which the under the foot part bedding boxes are easily accessible, a coil spring is effective on the toggle lever, which is pre-tensioned when the foot section is pivoted down »

The knee lever is designed so that it can be bent towards the foot of the mattress »

Those devices are required inside the bed-2-eugkastens a lot of space. In addition, tension springs are particularly sensitive to interference because one If a spring coil breaks, the function of the entire spring is lost.

The invention is now based on the object of providing a device as specified in the preamble of claim 1 Art while maintaining the advantages already achieved in the prior art improve that with simple means while reducing the space required a higher functional reliability than is achievable so far.

- 6 The solution to this problem is characterized by

that the toggle lever in the direction of the articulation axis

Swivel arms are arranged so that they can be folded in and that

'Tensioning compression spring is arranged.

On the one hand, this results in a considerably shorter overall length of the entire device. It is for Task solution conducive to when the compression spring is used

steered part of the toggle lever is articulated.

In order to obtain the greatest possible spring travel for the compression spring, it is advantageous if the most posed Articulation point of the compression spring on the end part of the base plate facing away from the toggle lever articulation point

is arranged.

An advantageous development of the above

f subject is also that in the toggle lever

feed at a different distance from its frame-fixed Connection elements arranged at the articulation point are provided for the optional connection of the compression spring.

This makes it possible with simple measures to adjust the device to the respective dead weight of the foot part adapt.

For this purpose, a variant which may be preferred under certain circumstances is characterized in that there are several in the base plate in the longitudinal direction of the compression spring at a distance from one another connecting members for optional connection the compression spring are provided.

To further increase the functional reliability it is advantageous if the compression spring is designed as a gas compression spring.

An embodiment of the invention is shown in Drawings shown and will be described in more detail below. Show it:

the latter, two pivot arms 3 and 4 are articulated so that they can pivot about a common axis 5. The swivel arm 3 carries a mattress head part 6, while a mattress base part 7 is supported on the swivel arm 4 - "'st The mattress base 7 is the bedding box 8 bounded by the mattress frame. On the swivel arm 3 a latching support 9 is articulated, the latches 10 of which with a latching bolt held fixed to the frame on the side cheek 1 11 cooperates,

The swivel arm 4 is supported by means of a toggle lever 12. Furthermore, one is effective on the toggle lever 12 Gas pressure spring 13 is provided on the one hand on the base plate 2 and on the other hand on the part 14 of the toggle lever 13 is articulated, which is articulated to the base plate. Here is the Toggle lever 12 arranged so that it buckles towards the pivot axis 5 when the foot part 7 is closed. Around To obtain the longest possible spring travel for the gas pressure spring 13, the latter is on the base plate the base plate end part facing away from the articulation point of the toggle lever 12 is provided.

The locking rail 9 is assigned a per se known slide 15 which, when the head part 6 is raised, in its upper end position is influenced by the locking bolt 11

is adjusted so automatically that it bridges the notches 10 in order to be able to pivot the head part 6 downwards without the locking rail engaging. Shortly before reaching the lower end position, the slide runs again on the locking bolt 11 in order to move the slide 15 back into the position shown in the drawings. On the other, not shown side cheek of the mattress frame is a gleir ¹ Ttige device described above arranged to t jeide devices in synchronism to take effect.

All new individual and combination features disclosed in the description and / or drawing are used regarded as essential to the invention.
