FR2804850A1 - Variable configuration bed or sofa for limited space or handicapped people has U-shaped frame and has two hinges, four bed parts actuated by pistons and move relatively to the mobile frame - Google Patents

Abstract

Frame is U-shaped and has two hinges, which can rotate for more than 90 degrees. Four bed parts (19-22) are actuated by pistons and moving relatively to the mobile frame to take various positions.

Description

This invention relates to the simplification of use of a bed convertible into bed with footrest, seat and head liftable by electric control (27).

Convertible sofa-bed also in table with electric lift and tiltable platform plus single bench with manually liftable seat.

Often the manipulation of a manually convertible sofa bed is not accessible to all (children, physically disabled, adults with low back problems, elderly).

Moreover, the various manual systems require concentration effort to the user to find the user manual deployment of a bench. The device of this invention overcomes these disadvantages.

Electric multiposition bench-bed.

A stationary U-shaped frame (1) (FIG. 5) to which is attached a set of hinges (2) and (25) pivoting more than 90 driven by two jacks (4) (5) allows four elements of the box spring slatted (19) (20) (21) (22) joined between bolts (23) flowing on a movable frame (7) to become multiposition. Moving to the bench seat position to the bed position.

Seat, foot and head liftable by remote control. Physical effort becomes non-existent.

The intervention will interest people with reduced surfaces, or physically handicapped, where frequent manual manipulation would quickly become tedious.

List of drawings Page 1I3 shows the different bed positions and the conversion into an electric bench seat.

Figure 1: flat bed position. Figure 2: raised head position.

Figure 3: raised head position, low seat and raised footrest. Figure 4: seat position (lifting seat).

Page 2I3 shows Figure 5. This is the motor part that supports and moves the elements of the slatted frame.

The <I> 3I3 </ I> page Figure 6: the elements (21) (22) can become tilting table liftable by the three cylinders.

Figure 7: on the frame (7) the elements (19) (20) become simple bench seat but possibility to raise the seat forward manually. This bench is as follows.

The stationary frame (1) is composed of three parts of strong sections that exist for the purpose of ballast stability of construction and fixing of the cylinders. In this frame comes slide the frame (7) moving on wheels.

On this frame (1) are fixed two hinges (2) and (25) each connected by an angle on which are fixed the two attachment points (front clevis) of the cylinders (4) and (). The other two fixing points of the cylinders (rear clevis) are fixed on the frame (1).

Four slat frame elements hinged together. fig 1, 2, 3, 4 The elements (21) (22) serve as a backrest. The element (20) serves as a backrest or seat. The element (19) serves as a seat or footrest.

The elements (19) and (20) follow the force of the movement of the elements (21) (22) (thrust or traction of the cylinders).

The four elements (19) (20) (21) (22) are connected to the frame (1) by the two axes (3) (Figure 5) of the hinges thereof.

The element (19) is the element furthest from the frame (1) in bed position. It is supported by chassis (7) carried by rollers (28) and movable from front to back from the bed position to the bench seat position.

A cable (8) prevents the frame (7) from reaching the end of the race. This cable (8) has the role of flattening the element (19).

Indeed, during the bench seat position the element (19) is at the end of the race thanks to two stops (24) whose roles are to stop the frame (7) to allow the lifting of the element (19). ) in a bench seat with raised seat.

The system operates by electric cylinder. The two cylinders (4) and (5) move the hinge block (2) from a vertical position to an angle below the horizontal front to back and vice versa.

The inclination of the elements (21) (22) can marry all the positions contained in the angle.

The cylinder (6) ensures the lifting of the headboard by the hinge (25).

It slides at its base in a slide in order to make up the few centimeters of offset during the movement of the hinge (2).

Although this is not its primary purpose, the bench-bed can also serve as a coffee table with a fixed bench by uncoupling only the two axes (18) at the ends of the hinge (2) and then rotating at l80 of the chassis (7) and lifting the element (19). Two shims can manually adjust the folder. The table top tilts thanks to the jacks.

Claims (6)

1) A multipositional electric bench-bed characterized by a stationary U-shaped frame (1) on which is fixed a set of hinges (2) and (25) pivoting more than 90 driven by two jacks (4) (5) allows four slat frame elements (19) (20) (21) (22) joined together bolts (23) flowing on a movable frame (7) to become multiposition. Moving to the bench seat position to the bed position. Seat, foot and head liftable by remote control. Physical effort becomes non-existent. The intervention will be of interest to people with soil surfaces, or physically handicapped people, where frequent manual manipulation would quickly become tedious. 2) Bench-bed according to claim 1 characterized by a jack (6) sliding in a guide (15) to compensate for the different movement of the two hinges (2) (25). 3) Bench-bed according to claim 1 characterized by two other cylinders (4) (5) operating together to ensure the stability of the hinge (2) and ensuring the transformation of bed bench (4) (5) pivoting by lever the element (20) on the angle (26) of the frame (7) for raising (19). 4) Bench-bed according to claim 1 characterized by two hinges (2) (25) connected to each other but dependent and independent movement to multiply the different positions. 5) A bench-bed according to claim 1 characterized by a frame (7) movable carrying flat irons (10) (11) (12) (13) for pivoting attachment for lifting and ensuring the guiding and mounting of the elements (12). ) (20). 6) bench-bed according to any one of claims characterized by a cable (8) for prematurely stopping the travel of the frame (7) and allow the hinge block (2) and (25) to fold down the element (19) of slats.
