Description
-~3~
The present invention rela-tes to a ~ed of which -the mattress-holde~ is made up o~ at least a seat-rest and a back-rest articulated to one another and mounted in mohile fashion on a ~rame in such a manner as to be able to form therebetween a variable angle.
More specif.ically, the bed according to the invention as herein claimed essentially comprises: a bed frame includiny a cradle integral thereto; a mattress-holder including a back-rest and a separate seat-rest; a carrier mounted on the cradle for rocking motion therealong; means mounting the back-rest on the carrier for rotation about an axis transverse of the back-restj intermediate its ends; means mounting the seat-rest at one end for rotation about an axis transverse of the seat-rest and further means mounting the other end of the seat rest on the frame for rotation about a further axis transverse of the seat-rest. There are further provided means to cause roc~ing of the carrier on the cradle and means articulating adjacent ends of the back and seat-rests to one another. Accordingly, when the carrier is rocked, along the cradle, the back-rest and seat-rest are inclined in opposite direction.
A preferred embodiment of the invention follows hereinafter with reference to the appended drawings wherein:
Figure L is a plan view of an articulated bed made according to the invention;
Figure 2 is a view in cross-section along line II-II
of Figure 1, and Figure 3 is a view similar to that o~ Figure 2 but illustrating the bed in a second position.
The illustrated bed is made up of a tubular frame 10, tha~ can be entirely taken to pieces, of a mattress-holder formed in three articulated parts: a back-res-t 11; a seat-rest 12 and a leg-rest 13; of a me-tal cradle :L~ having the shape of ~9~
an arc of circle and being integral with the frame 10; of a carrier 15, having in elevation the shape of a U, adapted to roll in the cradle 14, and of a compressed air jack 16, con-nected at one end to a transverse axle 17 of the carrier 15 - and, at the other end, to the base of the frame 10.
The back-rest 11 is mounted for ro-tation about the axle 17 whereas the seat-rest 12 is mourted for rotation, on the one hand, about a transverse axle 19 of the carrier 15 and, on the other hand, about a transverse axle 20 of the frame 10.
The back-rest 11 and the seat-rest 12 are, besides, elastically joined by two spring blades 21 fixed, on the one hand, to the axle 19 and, on the other hand, to a transverse axle 18 of the back-rest 11.
As to the leg-rest 13, it is pivoted on an axle 22 of the frame 10 and it is supported by a device comprising two toothed sectors 23 for adjust.ing its inclination.
The bed yet comprises a device, operable by a handle
The present invention rela-tes to a ~ed of which -the mattress-holde~ is made up o~ at least a seat-rest and a back-rest articulated to one another and mounted in mohile fashion on a ~rame in such a manner as to be able to form therebetween a variable angle.
More specif.ically, the bed according to the invention as herein claimed essentially comprises: a bed frame includiny a cradle integral thereto; a mattress-holder including a back-rest and a separate seat-rest; a carrier mounted on the cradle for rocking motion therealong; means mounting the back-rest on the carrier for rotation about an axis transverse of the back-restj intermediate its ends; means mounting the seat-rest at one end for rotation about an axis transverse of the seat-rest and further means mounting the other end of the seat rest on the frame for rotation about a further axis transverse of the seat-rest. There are further provided means to cause roc~ing of the carrier on the cradle and means articulating adjacent ends of the back and seat-rests to one another. Accordingly, when the carrier is rocked, along the cradle, the back-rest and seat-rest are inclined in opposite direction.
A preferred embodiment of the invention follows hereinafter with reference to the appended drawings wherein:
Figure L is a plan view of an articulated bed made according to the invention;
Figure 2 is a view in cross-section along line II-II
of Figure 1, and Figure 3 is a view similar to that o~ Figure 2 but illustrating the bed in a second position.
The illustrated bed is made up of a tubular frame 10, tha~ can be entirely taken to pieces, of a mattress-holder formed in three articulated parts: a back-res-t 11; a seat-rest 12 and a leg-rest 13; of a me-tal cradle :L~ having the shape of ~9~
an arc of circle and being integral with the frame 10; of a carrier 15, having in elevation the shape of a U, adapted to roll in the cradle 14, and of a compressed air jack 16, con-nected at one end to a transverse axle 17 of the carrier 15 - and, at the other end, to the base of the frame 10.
The back-rest 11 is mounted for ro-tation about the axle 17 whereas the seat-rest 12 is mourted for rotation, on the one hand, about a transverse axle 19 of the carrier 15 and, on the other hand, about a transverse axle 20 of the frame 10.
The back-rest 11 and the seat-rest 12 are, besides, elastically joined by two spring blades 21 fixed, on the one hand, to the axle 19 and, on the other hand, to a transverse axle 18 of the back-rest 11.
As to the leg-rest 13, it is pivoted on an axle 22 of the frame 10 and it is supported by a device comprising two toothed sectors 23 for adjust.ing its inclination.
The bed yet comprises a device, operable by a handle
2~, for locking the jack 16 -to holcl the carrier 15 i.n selec-ted position. An additional load 25 is mounted on the base of the carrier 15 and a coil spring 26 is mounted around the piston rod of jack 16. This rod is made of telescopic parts and the spring 16 extends between the axle 17 and a shoulder provided on one of the telescopic parts thus resiliently joining the piston of the jack 16 and the axle 17.
When the bed is not occupied and the jack 16 is actuated, the carrier 15 is subjected to two couples, opposing one another, respectively created by the bed's own weigh-t together with the weight of the additional load 25 (resultant P2) and by the force F of the jack 16.
The points of application and the s-trength of forces F and P2 are selected such tha-t the mattress-holder is practi-cally in a sta-te of stable balanc~ for all angular posi-tions of ~ 2 --~L39~
the carrier 15. In fack, the back~res-t 11 has a slight tendency t~ get upright.
When someone lies over the bed, the point of applica-tion of his weight Pl generally extends vertically throuyh the pivoting center o~ the carrier 15 in such a way that the state of stable equilibrium is practically not changed.
Under these conditions, the user may progressively incline the back-rest 11 up to the limit position illustrated by broken lines in Figure 3, and then block it in the selected position by acting on the handle 24.
In order to bring the back-rest to horizontal position, it is sufficient for him to move slightly back, that is towards the head of the bed in such a manner as to create, by movement of his center of gravity, a couple opposed to that created by the force F.
Tests have shown that a jack delivering a trust o~
from 15 to 20 kg is su~Eicient to provide ideal operation of the bed.
The purpose oE the spring 26 is to allow -the user to apply a sliyht rocking motion to the back-rest 11, in the manner of a rocking chair, once the jack is locked. ~his rocking motion favorizes relaxation when the bed is used as an arm chair.
The invention is obviously not restricted to the embodiment illustrated and described above. Particularly, the load 25 could be replaced by a spring system and the spring 26 by a more elaborate resilient device provided with means allowing to adjust the amplitude of rocking motion as a ~unction of the weight of the user.
It will be noted that the distance separating the back-rest 11 and the seat-rest 12 increases with the angle made therebe-tween so that, whatever be the value of this angle, the ~L~ 3~
mattress does not make any creases in that area. This represents an important advantaye from a medical point of view in the case of hospital beds as it thus removes one of the main causes of bedsores.
It will fi~ally be noted that the bed described above does not require the use of any electric motors which makes it autonomous and does not require any energy.
