Definitions

the present invention relates to an articulated frame for a bed, relaxation seat or armchair, comprising three parts mounted on a support, these parts respectively forming a backrest, a seat and a leg support.
the articulated beds are more particularly intended for hotel establishments, hospitals or convalescence, which are called upon to receive a large number of individuals of different sizes.
the comfort of a user in such a bed depends not only on the length of this bed, but also on the way it is articulated.
mass produced articulated beds have a standard length of 1.90 m. Longer beds, intended for tall people, are produced in small series and therefore cost significantly more.
the locking means generally used in articulated assemblies often include a clamping member acting on the two parts at their articulation, parallel to the axis of this articulation.
the clamping member is actuated by a control and blocking lever, which is ensured by the friction of the two parts against each other and which depends on the force exerted by the user.
An object of the present invention is to provide a frame for an articulated bed which can have several useful lengths, without any impact on the cost price.
Another object of the present invention is to produce an articulated frame for a relaxation bed or seat, provided with easy-to-use locking means, requiring no significant clamping force and cannot loosen untimely.
the articulated bed as defined above is characterized in that its frame comprises means for modifying the position of at least one of the end parts, backrest or leg support, by relative to the seat, to allow the total length of the bed to be modified, and locking means for locking the backrest in position relative to the seat.
the locking means comprise a strap fixed by its ends respectively to each end of the lever, at least one cam eccentric subjected to the action of a return spring tending to keep it in a position where it clamps the strap against a support plate secured to the support, and control means capable of rotating the cam eccentric against the action of the spring to release the strap.
the frame for an articulated bed comprises three parts, respectively a backrest 1, a seat 2 and a leg support 3. These three parts 1, 2 and 3 are mounted on a cradle 4 constituted by two sides 5 connected by bars 6 forming a spacer.
the backrest 1, the seat 2 and the leg support 3 are formed by two sides 7, 8 and 9 respectively connected by crosspieces 10. The latter are fixed at each of their ends in housings 11 of the sides 7, 8 and 9.
the backrest 1 is articulated on the cradle 4, a bore 12 of each of its sides 7 being traversed by a pivot 13 secured to each side 5 of the cradle 4.
the sides 8 of the seat 2 each have a slide 11 in which is engaged a bar 6.
an arcuate lever 15 pivoted on the side 5 of the cradle 4 connects the backrest 1 to the seat 2.
the one of the ends of this lever 15 pivots on the side 8 of the seat 2, while the other end of this lever 15 is guided in a slide 16 of the sides 7 of the backrest 1.
the sides 7 of the backrest 1 each have a second bore 17 capable of cooperating with a pivot 13 of articulation.
the pivots 13 are mounted in these bores 17, the useful length of the frame between the seat 2 and the backrest 1 increases by a size equal to the spacing of the two bores 12, 17, of each flank 7.
Horizontal beams 18 and 19 are fixed to the cradle 4 and extend respectively under the backrest 1 and under the leg support 3.
the beams 18 are made integral at their free ends with two feet 20 connected by a bar 21.
a headboard 22 is capable of being fixed in the extension of the feet 20.
the longitudinal members 18 constitute a stop for the backrest 1 when it is in a horizontal position, as illustrated in the drawing.
the longitudinal members 18 are constituted by two tubular profiles 23, 24, one engaged in the other.
the internal profile 23 has an elastic stud 25 capable of engaging in two holes 26 of the external profile 24.
the longitudinal members 19 are supported at their free ends by a pair of feet 27 connected by a bar 28.
the longitudinal members 19 each carry a pivot 29 capable of cooperating with one or the other of two bores 30, 31, provided in the sides of the leg support 3.
a locking device with notches 32 makes it possible to adjust the inclination of the leg support 3 with respect to the longitudinal members 19.
This device 32 cooperates with one or the other of two studs 33 according to the bores 30 or 31, in which the pivots 29 are engaged.
the crosspieces 10 serve as a support for a fabric 34, the ends of which surround the crosspieces 10 disposed at the opposite ends of the backrest 1 and of the leg support 3. So as to be able to keep the same fabric 34 regardless of how the articulations of the backrest 1 and of the leg support 3 are mounted, the crosspieces 10 serving for fixing to the fabric 34 are each capable of being mounted in two housings 11 of each side 7 and 9 of the backrest 1 and of the support - legs 3.
the frame described above is intended to receive a mattress 35 shown in phantom by the drawing.
a bed comprising this frame is capable of occupying all the intermediate positions between the horizontal position, as illustrated by the drawing, and the so-called relaxation position, in which the backrest 1 is raised.
a self-locking locking device 36 controlled by a lever 37 fixed to the seat, makes it possible to block the bed in a position desired by a user.
the use of a bed provided with this frame can modify its position by pressing more strongly on the backrest 1 or on the seat 2, after having released the locking device 36.
pressing more strongly on the seat 2 it sinks and the backrest 1 straightens; conversely, by pressing on the backrest 1, it is lowered and the seat 2 'is raised.
the articulated bed frame described above has the advantage of being able to have several lengths or even of being able to be modified in its length, without any of its constituent parts being replaced.
the file 1 has pivots capable of being mounted in two bores of each side 5 of the cradle.
the apparent length of the seat 2 is greater or less depending on the bores in which said pivots are mounted.
the leg support 3 could be capable of being articulated in several bores provided in the longitudinal members 19.
the frame shown in Figure 2 is intended more particularly to form a relaxation bed.
This bed comprises three parts, either a backrest A, a seat B and a leg support C, articulated on a cradle 1 forming a support and resting on the ground.
the cradle 1 is formed by two lateral flanks 2 connected by transverse bars 3 forming a spacer.
the parts A, B and C each consist of two lateral sides, respectively 4, 5 and 6, connected by crosspieces 7.
the latter serve for fixing to a canvas or several parallel straps, represented schematically by dashed lines 8.
the upper ends of the sides 2 of the cradle 1 have pivots 9 and 10.
the pivots 9 are engaged in bores in the sides 4 of the backrest A and the pivots 10 cooperate with slides of the sides 5 of the seat B.
Each side 2 of the cradle 1 also has an articulation pivot 11 for an arcuate lever 12.
One end of each of these levers 12 is engaged on a stud 13 of a sidewall 5 of the seat B, while the other end of this lever carries a stud 14 engaged in a slideway 15 of a sidewall 4 of the folder A.
the user of a bed with a frame of this kind can, depending on whether he presses more strongly on the backrest A or on the seat B, respectively lower or raise the backrest A, which corresponds to an increase or a depression of the seat B.
the arched levers 12 pivot relative to the sides 2 of the cradle 1. To block the bed frame in a given position, it suffices to angularly block these levers 12 relative to cradle 1.
a locking device 16 illustrated in FIGS. 2 and 3, is disposed on each side of the frame, fixed on the internal face of the sides 2 of the cradle 1.
Each locking device 16 comprises two cams constituted by eccentrics 17, 18, pivotally mounted between two parallel sheets 19, 20, these cams 17, 18 facing a support plate 21 integral with said sheets 19, 20.
Each cam 17, 18 has two lever arms, a first lever arm 26, at the end of which acts a spring 27 and a second lever arm 28, capable of cooperating with release means 29.
the eccentric cams 17, 18 resiliently press the strap 22 against the support plate 21.
These two cams 17, 18 are arranged so as to block the strap 22 by self-tightening against the plate support 21, each in a direction of movement of the strap 22 relative to the support plate 21.
the strap 22 When, for example, the strap 22 moves from the left to the right in FIG. 3, it frictionally drives the cam 17. The latter pivots and, by its shape, increases the tightening of the strap 22 against the support plate 21 until it locks.
the unlocking means 29 comprise an eccentric 31 capable of cooperating with the ends 30 of the lever arms 28.
This eccentric 31 is pivotally mounted between the two sheets 19, 20, on an extension of the articulation axis 11 of the lever 12.
the eccentric 31 is angularly integral with two pulleys 32, 33.
On the first pulley 32 is wound a cable 34 subjected to the action of a return spring 35.
the second pulley 33 visible in FIG. 2, is wound by one end of an actuating cable 36, the other end of which is made integral with a sector 37 pivotally mounted on a side 5 of the seat B, along an axis whose distance from the axis of pivoting of the eccentric 31 is substantially constant for all the positions of the armature.
Sector 37 is angularly secured to an actuating handle 38 and has an abutment spout 39 bearing cort.2e a stud 40.
the sectors 37 each arranged on one side of the bed frame, are angularly rendered integral with each other, so as to be actuated simultaneously by a single actuating handle 38.
the locking device can easily be operated by the user. Furthermore, untimely unlocking is impossible.
the seat B and the backrest A can pivot slightly in one direction or the other, which ensures a certain flexibility in the seat and the backrest, and thereby more comfort for the user.
the circular sector could bear around its periphery a friction lining.
