- the displacement of a leg rest 6 movable relative to a base 2 and to a seat 5 remaining in line with said base 2 is advantageously authorized, whatever the elevation angle of the seat and the angle of tilt of the legrest, by the use of 14L longitudinal members of the upper frame 14 shortened, which stop substantially above the popliteal link 27.
- This constructive arrangement advantageously makes it possible to cross the legrest 6 the upper frame without hitting the rails 14L and without having to raise before him or the seat, to place it entirely above said rails 14L.
- the upper longitudinal members 14L may have a movable structure longitudinally, and more particularly extensible, for example telescopic, so as to be able to deploy to come to support the sleeping plane 3 when the bed is in a clustered configuration and to retract in order to clear the passage at the legrest 6 when passing into the clearance configuration.
- the seat 5, and preferably the backrest 4 are mounted on a movable carriage 30 guided laterally relative to the upper frame 14, for example by means of one or more rails 31. It is remarkable that, in order to rationalize the production, it is conceivable to use as support for said carriage 30 two rails using profiles and logs identical to those used to form the tubular element 23 and the slide 25 constituting the common member 22.
- the seat 5 which is laterally offset to present its flange 5S in overflow left or right of the base, and more particularly in overflow of the upper frame 14, and on the other hand where the legrest 6 remains plumb with said base 2 during the release operations, it is perfectly possible to maintain any tilting angle Ji, whatever the angle of elevation ⁇ (positive) chosen for the seat.
- the legrest 6 must not be embarked laterally, the upper frame 14 is not an obstacle, and the legrest 6 can therefore be inclined to the ground before and during the movement of the carriage mobile 30 without ever annoying said displacement.
- the bed 1 according to the invention makes it possible to maintain the comfort settings, that is to say more particularly the adjustment of the elevation angle ⁇ of the seat 5, tilting ⁇ of the legrest 6 and recovery ⁇ of file 4, operational at any time, whether the bed is in a group configuration or in a clearance configuration.
- attitude adjustment means - so comfort - according to the invention may advantageously be independent of each other and independent of the retracted configuration or clearance of the bed 1.
- the trim adjustment means 21 preferably comprise one or more retaining members 40, 40 ', 40 "of variable length, such as cylinders 41, 41 ', 41 "or toothed rods, each of which connects a bearing element 42, 42', 42" integral with the base 2 to a respective levitation element 43, 43 ', 43 ". seat 5 and / or leg rest 6 and / or backrest 4.
- the bearing elements 42, 42 ', 42 may advantageously be formed by rods transversely joining the longitudinal members 14L of the upper frame 14, substantially parallel to the transverse direction (YY' ) of bed 1.
- the levitation elements 43, 43 ', 43 may advantageously be formed by rods joining transversely the lateral elements of the portions of the bed base 7 which correspond respectively to the seat, the legrest and the dpssier, substantially parallel to the transverse direction (YY ') of the bed 1.
- the support elements will be placed at an altitude lower than that of the junction points of the respective pivot connections of the seat, the legrest or the backrest, in order to create triangular structures allowing the appearance of a lifting torque capable of lifting the levitation elements.
- the support elements may possibly be lowered to allow a movement of an element of the sleeping surface 3, such as the legrest 6 or the backrest 4, below the level of the upper frame 14.
- the retaining member 40, 40 ', 40 is mounted to be movable in translation, and more particularly as a sliding pivot, with respect to the bearing element 42, 42', 42" and / or the levitation element 43, 43 ', 43 "so as to accompany at least partially the lateral displacement of the leg rest 6 relative to the seat 5 or vice versa.
- the mobility in translation is free, so that the retaining member 40, 40 ', 40 "is spontaneously driven in displacement by the movable member (seat or leg rest) when it abuts against said means of support during its transition from the cluster configuration to the clearance configuration.
- the retaining member 40, 40 ', 40 is provided with a guide reinforcement 45, 45', 45" intended to prevent the bending or bracing of said support member during its displacements by relative to the support member 42, 42 ', 42 "and / or the lift member 43, 43', 43".
- said guide member 45, 45 ', 45 is extensible and retractable in the same direction as said support member.
- the guide reinforcement 45, 45 ', 45 is formed by a telescopic frame.
- the width of the telescopic frames is not limited, and may in particular vary depending on whether the element of the sleeping surface that is associated with the corresponding support means is intended to be laterally movable or, conversely, fixed.
- the telescopic frame may advantageously extend over the entire width of the interlonge 14L space to form a stop blocking the lateral translation of the corresponding element of the coating plane relative to the base, such as this is the case of the telescopic frame 45 'associated with the legrest 6 in FIG.
- the translational lateral clearance means 21 are preferably bidirectional and arranged to alternatively allow the displacement of the seat 5 and / or the legrest 6 of the seat. left side or right side of the bed, at the discretion of the user or according to the constraints of space, transient or durable, related to the configuration of the room in which the bed 1 is implanted.
- Such a bed therefore has a great versatility of use.
- such bidirectional clearance means may comprise on the one hand an accompanying telescopic rod 50 and on the other hand movable hinges 51, designed to be alternately on board and deposited by the terminal section. of said telescopic rod 50, to accompany the movement of guns 53 attached to the legrest they support by means of hinges 52.
- the seat 5 and the legrest 6 can be dissociable, for example at the level of the popliteal connection.
- the sleeping surface 3, and more particularly the bed base 7, may be provided with reversible connecting members, respectively fixed to the seat 5 and the legrest 6, and for example located substantially at the edges. respective separation of these.
- Said connecting members are designed to be alternately coupled, in an association configuration in which they realize a mechanical connection, for example of embedding type or pivot connection (in this case, poplitated), and separated, in a dissociation configuration in which the degree or degrees of freedom that had been removed in association configuration are restored, that is to say in which it removes the direct junction existing between the seat and the legrest.
- a mechanical connection for example of embedding type or pivot connection (in this case, poplitated)
- dissociation configuration in which the degree or degrees of freedom that had been removed in association configuration are restored, that is to say in which it removes the direct junction existing between the seat and the legrest.
- the seat is provided with own trim adjustment means that allow to increase its elevation angle, that is to say, to tilt slightly rearward of so as to raise its separation edge 5S above the separation edge 6S of the legrest at the time of operating the lateral translation.
- the patient is lying flat on the sleeping surface 3.
- the elevation ⁇ , tilt and recovery angles ⁇ are all substantially zero.
- the various members of the attitude adjusting means 21 may advantageously be electronically controlled to provide a joint and coordinated operation of several components of the sleeping plane 3, depending on the desired configuration (bed, chair, release. ..)
- the caregiver can help the patient to get up, or access the back of the legs to provide care, by following the steps below.
- the legrest 6 is driven following the seat 5 via the popliteal connection 27.
- the pivot connections provided between the support member 40 'of the legrest 6 of a the corresponding supporting elements 42 'and levitation 43' advantageously allow the movement to develop, forming with the seat 5 and the upper frame 14 a structure close to a parallelogram.
- the caregiver retracts the telescopic upper beam 14L located on the side corresponding to the intended direction of disengagement (for example to the right of the bed) so as to clear the passage side for the patient's legs when they leave the legrest.
- the carer then unlocks the movable carriage 30 by extracting the locking pin 15, then pulls on said carriage 30, for example at a side handle (not shown) specially provided for this purpose on the side edge of the bed base 7 .
- the caregiver can thus extract the carriage 30 in the lateral overhang of the bed 1, and more precisely cantilevered with respect to the base 2, by progressively sliding along the rails 31, for example to the right in the figure 6.
- the telescopic frame 45 can thus advantageously constitute a limit stop preventing for example accidental total disengagement of the carriage 30 from its rails 31.
- the bed is then in the clearance configuration, as shown in FIG.
- the patient is trained at the same time as the seat 5 on which it is located, so that its legs are gradually pulled laterally from the legrest 6 to hang freely over the separation edge 5S.
- the caregiver can then adjust the overall height of the seat using the elevator means 10 to bring the patient's feet to the ground so that it finds a natural and stable support.
- the bed 1 according to the invention has a great simplicity, both structure and use, and ensures the safety of the patient and the caregiver.
- such a bed can offer a real chair position, or chair, in which the patient is perfectly supported at the level of his back and thighs, while enjoying a clearance of the rear portion of his legs.
- Such an arrangement not only facilitates the lifting of the patient without discomfort for the latter or vicious lumbar position for the caregivers who accompany it, but also provides direct access to the calves and heels so that the caregiver has both hands free to provide care, without the need to lift and maintain the patient's legs above the mattress.
- the bed according to the invention therefore enjoys excellent ergonomics.
- the bed according to the invention is able, if necessary, to substantially maintain the horizontal attitude of the legrest during the frontal release of the seat, thus preventing the falling of the bedding elements or preserving them at all. less of an anti-hygienic contact with the ground.
- the invention finds its industrial application in the design and manufacture of medical beds.
