Definitions

  • the present invention relates, in particular in the hospital field, to handling installations which make it possible to facilitate an intervention on the underside of a piece of furniture such as a bed or a stretcher.
  • the invention relates more particularly to a system for handling rolling sleeping units and a method for positioning a rolling sleeping unit.
  • the method of fixing can also cause damage to the elements of the bed engaged with the arms and the attachment members, due to the rotational movement (with torsional forces).
  • Such solutions require the use of two motorized elements, distributed over two guide columns, to actuate the lifting of a pair of arms. This can result in torsion problems for the bed structure.
  • the aim of the present invention is therefore to alleviate all or part of the aforementioned drawbacks by proposing a system for handling objects which easily makes it possible to lift and modify the orientation of a rolling sleeping unit, such as for example a bed. hospital or stretcher.
  • the rolling sleeping unit is permitted. It is sufficient to engage a longitudinal edge of this unit against the stop surface when positioning in the lifting area.
  • the lift portion is then placed under the sleeping unit, typically between the wheels, so that the technician does not need to adjust ties at opposite ends of the bed.
  • the retaining element typically located above the level of the sleeping unit, makes it possible to lock the relative position of the sleeping unit with respect to the receiving assembly.
  • the downward movement of the retaining element can optionally be actuated by a positioning control and the final contact position can be obtained by using one or more sensors. It is understood that this retaining element makes it possible, in association with the lifting part, to sandwich the sleeping unit (in the manner of a vice).
  • the receiver assembly is thus robust and can have a swing format which facilitates the approach and reception phase of the sleeping unit, with correct positioning. above the lifting part; this configuration allows adaptation to a very wide range of medical beds with high weights that can exceed 400 kg with a safety margin.
  • the system comprises second drive means for rotating the receiver assembly around the axis of rotation which passes through the two sliding ends, after lifting of the support device loaded with the sleeping unit, so as to orient the determined longitudinal edge downwards in the maintenance configuration of the sleeping unit.
  • these second drive means are configured to rotate the receiver assembly by a maximum of a quarter turn, the angle of rotation being configurable by a man-machine interface.
  • the lifting part can be designed and arranged to position itself under a central area of the sleeping unit (thus typically positioning itself under the center of gravity of the sleeping unit, so that the lifting part can be positioned). only part of the lifting provided in the system).
  • the support device is mounted so as to slide on the guide column by a sliding portion fixed to the guide column and guided vertically along the guide column.
  • This sliding portion is moved linearly by first drive means which allow the lifting of the support device.
  • the receiver assembly is thus mounted to pivot about a substantially horizontal axis of rotation defined by an articulated connection between the sliding portion and the receiver assembly (connection which is located further forward with respect to the guide column to allow the rearward displacement of the top of the receiver assembly), whereby the sleeping unit can also be lifted and held in an orientation changed by the support device.
  • the support device attached to the single guide column, is suitable to support the sleeping unit on its own, by engaging under a central area of the sleeping unit, typically through a long side of the sleeping unit.
  • the lifting part of the support device is designed and arranged to distribute rollers of a sleeping unit on either side of the lifting part.
  • the receiver assembly is made to be movable in rotation around the axis of rotation by second drive means which may optionally include at least one cylinder oriented transversely with respect to the guide column, knowing that the axis rotation is maintained at a constant spacing from the guide column which is typically fixed, regardless of the height level of the support device.
  • the method advantageously allows the medical beds and stretchers to be raised without performing physical efforts or making critical manual adjustments to the lifting.
  • the receiving assembly may have a bottom (lifting part), a holding element from above, and retaining means which form for example both a back (typically delimited by a rear frame and forming the stop surface) and a pair of sidewalls, so as to define a receiving housing for the sleeping unit. Access to this housing is from the front of the receiver assembly, without obstruction since the roller feet of the sleeping unit allow the bed base to be positioned above the lifting part. After having engaged the sleeping unit between the sidewalls and against the stop surface, all that remains is to adjust the retaining element (operation which can be automated), so that the technician no longer needs to move the sleeping unit.
  • the receiver assembly 10 has a lifting part 6, here formed by a fork, the length L of which is typically sufficient to allow engagement under the sleeping unit. This length is for example greater than or equal to 120 cm, and preferably at least equal to 140 cm or 160 cm.
  • the support device 3 In the loading configuration, the support device 3 is in a lowest position, the sliding ends EC1 and EC2 being placed near a base of the parallel / vertical columns forming the guide parts 4, 5. This configuration allows the sleeping unit 2 to be engaged against a stop surface 7 defined by the receiver assembly 10 and which extends transversely above a rear end of the lifting part 6.
  • the sleeping unit 2 here in the form of a medical bed ( figure 2 ), can be transported, by simply rolling it, to the lifting zone Z, and by orienting it so as to first engage a determined longitudinal edge 2a against the stop surface 7 formed by the receiver assembly 10
  • the abutment surface 7 is defined in particular by a frame 8 and by support elements 9 which support members spaced from the part of lifting 6, here the teeth of a fork.
  • the abutment surface 7 can thus be formed on a substantially planar framework delimited by the frame 8 and which extends perpendicularly to the lifting part 6.
  • any retaining means 8, 9 suitable for define such a stop surface 7 an opaque plate can thus be used for example).
  • the retaining means 8, 9 extend on the side opposite to the access for the sleeping unit 2.
  • the lifting part 6 which extends as close as possible to the floor of the workshop or plinth S of the system 1 is connected on one side to the retaining means 8, 9.
  • the support elements 9 can be mounted so as to be able to slide along at least one hooking rail 11. which forms part of the receiver assembly 10.
  • the desired position of these support elements 9 is for example locked by removable fixing elements, typically with a clamping.
  • the distance E in length between the feet 22 or similar base elements is typically greater than 100 cm, so that the lifting part may have a width L6 typically less than but close to this distance, this width L6 being able for example to be at less equal to half of the total length of the sleeping unit 2.
  • the lifting part 6 stays away from the end panels 14a (foot side) and 14b (head side) and these ends can therefore differ widely from one sleeping unit 2 to another, without this hindering the movements allowed by the handling system 1.
  • the mobility of the support elements 9 makes it possible to adjust the width L6 of the lifting part 6, while preserving an overall rigidity of the receiver assembly 10. It can be observed on the figure 1 that the width L6 is less than the length L of the lifting part 6, so that this part 6 of the receiver assembly 10 is longer than it is wide.
  • the lifting part 6 has two spaced rigid members 6a, 6b, for example two teeth to form a fork, each provided on the top with a less rigid coating.
  • contact surfaces 12 made of flexible and / or deformable material (for example made of elastomer, natural rubber or suitable polymer) are defined to engage the underside of sleeping unit 2. This is to avoid damaging the lower surfaces of sleeping unit 2.
  • the frame of the handling system 1 can be secured to the ground, in particular by screws in the ground. This makes it possible to support heavy loads.
  • the system can also be optionally secured in part (at least) to any other substrate of the building which has a resistance comparable to that of a floor.
  • the base S here in a substantially rectangular tray format, may have long sides, at least one of which is provided with a ramp 29 allowing a sleeping unit 2 to slide or roll in the vicinity of the lifting zone Z, to from the ground to the upper surface of the plinth S.
  • the BD base or tread is horizontal at least in the lifting zone Z.
  • the lifting part 6 is slightly raised, and extends for example to a height H6 less than or equal to 25 cm, and preferably less than 20 cm relative to this flat base.
  • the base S constitutes an option which has in particular the advantage of allowing fine adjustment of the positioning of the two guide parts 4, 5.
  • variants are provided which possibly make it possible to eliminate this base S. in the case of figure 5 , the S base can be deleted.
  • the fact of using a guide column 4 'which is unique makes it easier to dispense with a base S.
  • the handling system 1 can be made mobile, for example by having roller feet 1c, as illustrated in figure 6 in the case with a guide column 4 'which is unique.
  • a stationary position can be maintained by a DS stabilizer device with complementary legs 52, which is adjustable in height and allows a vertical pushing force to be exerted against the ground or any suitable support surface. Threaded rods or rods provided with locking elements can make it possible to adjust in height the position of the complementary feet 52, which terminate here in a shoe 54 with a flat surface in contact with the ground.
  • the complementary feet 52 are mounted vertically movable in a generally horizontal structure, here a "U" structure, which at least partially delimits a lifting zone Z.
  • the lowering of the pads 54 can be carried out manually by cranks 53 or other gripping members.
  • the structure equipped with casters 1c can equip a handling system 1 which has several guide columns 4, 5 preferably distributed on either side of the lifting zone Z, which allows this system 1 to be moved more easily (with a high position of the complementary feet 52).
  • the extension length D50 of the stabilizer device DS can be greater than 2 meters and, here greater than the distance E in length between the feet 22 of the sleeping unit 2.
  • the elongated teeth forming the rigid members 6a, 6b of the fork each extend from a proximal end 60 (near the abutment surface 7) to an end 6c which is distal with respect to the abutment surface 7.
  • These rigid members 6a, 6b thus pass through the passage defined between the two guide parts 4, 5 and can be distributed on either side of a vertical median plane of the lifting zone Z (this virtual median plane extending to equal distance of the two guide parts 4, 5).
  • the ramp 29 can extend upstream of this lifting zone Z, for example more than 50 cm upstream with respect to the ends 6c of the lifting part 6. It is understood that the stop surface 7 delimits the end rear of the Z lift zone on these figures 1 and 3 .
  • the support device 3 is movable by lifting to lift a rolling unit 2, and guidance of the lift is enabled by enveloping surfaces formed around the guide parts 4, 5 by the sliding portions or ends EC1, EC2.
  • the mechanical drive to achieve this lifting is for example allowed by a motorized element 30 which is associated with one of the two sliding ends EC1, EC2.
  • a motorized element 30 which is associated with one of the two sliding ends EC1, EC2.
  • another lifting member of a type known per se is used, for example a chain of a lifting mechanism associated with the guide part 5, so as to define a motor drive with guidance along this part of guide 5.
  • the motorized element 30 can drive a chain (not shown) which is housed in a housing defined by the guide part 5.
  • the vertical sliding movement is then a free movement (slave guide zone).
  • a rotating drive motor M in conjunction with a control panel, a remote control or other man-machine interface, may also be provided on the side of one of the two sliding ends EC1, EC2, in order to rotate the receiver assembly 10 in a controlled manner. After lifting the support device 3 loaded with the sleeping unit 2, the receiver assembly 10 can be moved so that the determined longitudinal edge 2a faces downwards and thus obtains a maintenance configuration of the sleeping unit 2.
  • each of the sliding ends EC1, EC2 can have a pivot with a common axis of rotation X which is horizontal.
  • the receiver assembly 10 thus makes the connection between the end parts of the support device 3, by means of two aligned and opposite pivots (located on either side of the sleeping unit 2 when the latter is positioned in the lifting zone Z).
  • a connecting shaft is typically provided in each of the sliding ends EC1, EC2 to carry the receiver assembly 10 and its load.
  • a link shaft 40 can if necessary simply be a follower, while the other link shaft is a motor.
  • the axis of rotation X here passes through the two sliding ends EC1, EC2.
  • Two feet 22 of the sleeping unit 2 are typically placed between the abutment surface 7 and the axis of rotation X, so that this axis of rotation X is closer to a median plane P of the sleeping unit. 2.
  • the axis of rotation X can be optionally shifted rearwardly relative to the passage delimited between the two guide parts 4, 5, with the motor M placed just behind a column forming the guide part 4. This limits the risk of direct impact against drive parts of the system 1 when placing the sleeping unit 2.
  • the axis of rotation X can be located lower than the median plane P.
  • the drive connection of the motor M makes it possible to rotate the receiver assembly 10 by a maximum of a quarter of a turn, the angle of rotation being for example configurable by a man-machine interface of the control unit 15.
  • the lifting cylinder in particular electric, may advantageously be housed in a casing of the column or guide part 4.
  • Such a cylinder may be screw-type, irreversible, in particular driven by an electric motor. With such an actuator, it is possible to easily control and block the position of the sliding ends EC1, EC2, whatever the inclination of the receiver assembly 10, without requiring the compulsory presence of a brake. Whatever the rotational torque exerted on the pivots of the support device 3, the irreversibility of the screw makes it possible to prohibit the rotation of the receiver assembly around the axis of rotation X. For safety reasons, a brake additional is not excluded and can be expected.
  • the detection of a correct positioning of the sleeping unit 2, in the loading configuration is for example enabled by one or more sensors to detect an engaged position of the sleeping unit 2 against the stop surface 7. It may be a contact sensor 16 provided to deliver corresponding detection information.
