DE202017002902U1 - Space-saving double use for bench and bed, z. B. in trailers and campers, by means of rotation of the bed and the backrest about a common, eccentric axis of rotation - Google Patents

Abstract

Space-saving double use for bench and bed by rotation of the bed and the backrest about a common, eccentric axis of rotation, characterized in that bed (6) and backrest (1) via two outside of bed (6) and backrest (1) located pivot bearings (2 ) Are rotatably mounted and that the axis of rotation (2) in the region of the separation between the seat cushion (3) and backrest (1) and for the conversion, a rotation angle of about 90-110 ° is described.

Description

Current situation

There are room situations in which multiple uses are required due to the very limited existing living space. Typically this often affects the functions "sitting" and "sleeping". By evening renovation and morning demolition is from a seating area a sleeping area and vice versa. Among other things, such solutions are used in trailers and mobile homes.

Either arises by re-arrangement of the seat cushion a lying surface or there are so-called lift beds are used, which are arranged during the day on the room ceiling and lowered at night.

Disadvantages of current solutions

A rearrangement of the seat cushion to a multi-part sleeping pad is tedious and time-consuming. It is also usually not exactly level and sensitive people feel when lying the separations of the individual upholstery elements. Every night, the sheets must be raised and duvet and pillows are laid up. During the day is disadvantageous that duvet, pillows and sheets have to be deposited somewhere in the room. In addition, the mostly loose seat and back cushions offer only limited seating comfort during the day.

The alternatively used lift beds have the following disadvantages: They are very complex, they limit the room height and usually only go down so far that climbing the bed is difficult for physically less articulated persons. In addition, lift-bed mechanisms are expensive, heavy, and transmit high forces to the surrounding materials to which they are attached. Installed in the vehicle, the high weight-center of gravity is disadvantageous.

Problem solving, advantages (see also the list of numbers and drawings)

By means of the features described in the claims the above problems of previous solutions are eliminated. In a few seconds, from a comfortable seating, which also has an ergonomic inclination of seating ( 3 ) and back surface ( 1 ) offers a comfortable bed ( 6 ) with continuous, one-piece mattress. On 1 to 4 you can see the bed width ( 6 ). The bed can be used as a narrow single bed ( 3 and 4 ) or wider double bed ( 1 and 2 ). The bed length is freely selectable.

First, the table ( 4 ) lowered and then the high backrest ( 1 ), at the back of which the bed mattress ( 6 ) about 90-1100 about the axis of rotation ( 2 ) until the mattress ( 6 ) is horizontally positioned and by means of a support and locking ( 5 ) is fixed.

The sheet can stay permanently wound and also duvet and pillows ( 7 ), held by several straps ( 8th ) or a tension net, on the mattress ( 6 ). The room height is not reduced, the weight and center of gravity are lower, it is not a complex, expensive mechanism required, but only two external hinges ( 2 ), one between seat cushions ( 3 ) and backrest ( 1 ) generate running axis of rotation.

Claims (5)

Space-saving double use for bench and bed by rotation of the bed and the backrest about a common, eccentric axis of rotation, characterized in that bed ( 6 ) and backrest ( 1 ) over two outside of bed ( 6 ) and backrest ( 1 ) located rotary bearings ( 2 ) are rotatably mounted and that the axis of rotation ( 2 ) in the region of the separation between seat cushion ( 3 ) and backrest ( 1 ) and for conversion a rotation angle of about 90-110 ° is described. Bench and bed according to claim 1, characterized in that bed ( 6 ) and backrest ( 1 ) are firmly connected. Bench and bed according to one of the preceding claims, characterized in that bed sheet, duvet and pillow ( 7 ) on the bed ( 6 ) and on this by several straps ( 8th ) or an elastic tensioning network are fixed. Bench and bed according to one of the preceding claims, characterized in that only a rotational movement about an axis ( 2 ) and no other lifting or sliding or further rotary movements are required. Bench and bed according to one of the preceding claims, characterized in that the horizontal bed position ( 6 . 2 and 4 ) by one or two corresponding lockable pads ( 5 ) and these pads are attached to surrounding walls and / or adjacent furniture.
