    The present invention relates to the field of bed support frame. The present invention relates more particularly to a system for synchronizing the movements of twin bed frames.
    BACKGROUND OF THE INVENTION
    A problem in the field of bed support frame concerns the possibility during cleaning operations to lift the beds for maintenance staff to a height of comfort for the work dependent on each person. In hotels, rooms may have twin beds. One difficulty is to be able to lift the two beds in a synchronized manner to facilitate the cleaning of the maintenance staff, limiting them and facilitating the operations to be performed.
    It is known in the prior art synchronization systems as presented in patent DE 4405619. This device controls the heights of a hospital bed and a bedside table.

    DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
    The present invention relates to a synchronized bed lift device.
    The terms "right" and "left" are used in the present description in the meaning of "the two opposing flanks or sides" and should not be interpreted in a limiting manner. In general, with reference to FIG. 1, the present invention preferably comprises at least two bed lift frames (C1, C2) (L1, L2) that can be positioned at selected variable heights and a system for synchronize the movements of the bed frames.
    In some embodiments, with reference to Figure 2, each frame preferably comprises a lower structure (I) disposed on the ground and an upper structure (S) connected by four arms to the lower structure. The arms are pivotally mounted around the lower structure making it possible to make the upper structure with respect to the lower structure movable by translation in planes parallel to the ground, between a plane situated at a minimum height with respect to the ground and defining a low position and a plane located at a maximum height with respect to the ground defining a high position, according to the configuration of two deformable parallelograms.
    In some embodiments, the bed frames of the device are similar. For each frame, the lower structure comprises at least two parallel bars (1, 2) connected by a crossbar (3), preferably substantially eccentric from the middle to the left side, and the upper structure (S) comprising two bars (4, 5) parallel to the bars (1,2) of the lower structure. The lower structure and the upper structure are connected by four arms (6, 7, 8 and 9), two left lateral arms (6, 7) and two right lateral arms (8, 9), preferably placed close to the ends of the bars (1,2).
    In some embodiments, for each frame, an actuator cylinder (10) connects the lower structure and the upper structure. Preferably this cylinder connects the cross member (3) of the lower structure and a cross member (14) connecting the right side arms (8) and (9). Preferably, the jack is fixed substantially to the middle of the cross members to balance the thrust force of the jack on the frame. The cylinder can be positioned according to the two possible configurations, namely the lower part of the cylinder piston is connected to either the crossbar (3) or the crossbar (14). Preferably the jack is positioned so that the cylinder piston is connected to the cross member (14) connecting the right arms (8) and (9) because this configuration allows the electric motor of the cylinder to be positioned on the structure lower close to the ground. The electric motor of the cylinder is powered by a generator via an electric transformer (11). Preferably the transformer of the electric generator is fixed on the crossbar connecting the two left side arms (6) and (7) of the frame. The connection between the electric motor of the jack and the transformer can advantageously pass in or along the frame structures for concealing the electrical son. The actuator actuator has the advantage of being able to lift high weight including consistent with the weight of the assembly consisting of the frame, the bed base and the bed. This electric actuator actuator makes it possible to move the upper structure relative to the lower structure. Indeed, when increasing the length of the cylinder by acting on the electric actuator, the movements of the two deformable parallelograms are pulled upward by acting on the movements of the lateral arms (8,9) through the action of the cylinder on the crossbar (14). This increases the height of the chassis. In the same way, when decreasing the length of the jack, it reduces the movements of the two parallelograms down and decreases the height of the frame. This jack makes it possible to position the chassis at determined heights and chosen by the user by controlling the rise and the descent of the jack. Locking the chassis to a chosen height is determined by locking the cylinder to a predetermined length by stopping its movements. Thus, when the frame is locked at a given height between the low position and the high position, the latter is stabilized and the application of pressure, within the limits of the cylinder specifications, does not allow to lower the frame of manual way.
    In some embodiments, the actuator actuator cylinder can accurately control, to millimeters, the length of the cylinder. The length of the cylinder controlling the height of the frame, it is therefore possible to control the height of the frame to millimeters on the rise, as the descent of the frame.
    In some embodiments, the electric generator of the cylinder is a system of electric batteries, preferably rechargeable. The batteries must be configured to give the necessary power to the electric motor of the cylinder to allow lifting the frame and bedding .. Preferably, the battery system is fixed at a place under the bed base so as to make it invisible to the customer but arranged in an area easily accessible to the user. This means has the advantage of making the autonomous energy chassis to have them independently of the positioning of the electrical sector and without being cluttered and interfere with electrical son.
    In some embodiments, the electric battery system includes a charge indicator. This indicator is used to determine the charge level of the electric batteries so that they can be changed if necessary. This indicator can also be common to multiple chassis to facilitate user observation of the different current load levels at a single observation point. Advantageously, the charge level on the battery system is also accessible remotely avoiding the user to lower to control the charge of the electric battery system.
    In some embodiments, each frame comprises a control box (12) connected to the jack and preferably also connected to a power supply via its transformer, advantageously this power supply is identical to that of the electric jack. This electronic box makes it possible to control the electric actuator which controls the movements of the piston in the jack and thus to act on the length of the jack, namely its deployment or its retraction. As a result, the housing allows the user to raise or lower the frame between a low position and a high position and to stabilize the latter at a given height.
    In some embodiments, the electronic control unit of the electric actuator is placed near an edge of the bed, preferably below the bed and preferably in the middle of the side corresponding to the right side of the frame. This positioning favors remote control of the functions of the control box. By way of nonlimiting example, the remote control is effected for example by infra-red channels using an infra-red remote control.
    In some embodiments, an electronic controller is incorporated in the control box for each frame constituting the bed lift timing device. This electronic controller makes it possible to take control of the electronic controls of the corresponding control box when a link (13) is detected with another control box of another bed frame. A connecting means makes it possible to establish a relationship of servitude between the two control boxes. With reference to FIG. 3, in a first housing, called master (121), the connecting means makes it possible to activate a transmitter software (161) of its electronic controller (151), while in the second housing, called a slave ( 122), the link means activates a receiver software (172) of its electronic controller (152). This then allows the controller of the master box, activating the sending software, to receive the commands from its control box and transmit them using the connection means to the controller of the slave box, activating the receiving software, which forces them to its control box. The slave box then imitates the same controls of the master box for synchronizing the movements of each bed frame of the bed lifting device.
    Preferably, when a servitude relationship occurs between two control boxes, such as when the receiving software is activated in the slave box controller, the slave box controller automatically disables the remote control controls (182) that it receives not to interfere with the commands from the master box.
    In some embodiments, the connecting means for matching the movements of the chassis of the bed lifting device is an electronic cable. This cable provides a robust connection between the two control boxes and avoids electronic interference from other remote controls.
    In some embodiments, the service relationship between the master and the slave can be interrupted or reactivated, by way of non-limiting example, either by disconnecting or connecting the connecting means, or by deactivating or activating the controllers of the control boxes. Advantageously activation and deactivation on the controllers of the control boxes can be done by a remote control. This function allows the user, as needed, to separate the movements of the two bed frames that make up the bed lift synchronization device and work at different heights, especially for the change of beds.
    In some embodiments, with reference to FIG. 2, the upper structure of the frame comprises parallel bars (4, 5). These bars have lateral notches (22), preferably near the ends, for introducing sleepers (19, 20). These last allow the support of the bedding and stabilizes the bedding during the movements of the frame by distributing the forces applied on the whole of the surface.
    With reference to FIG. 4, these crosspieces are advantageously perpendicular to the bars and the two crosspieces of a flank, left (191, 192) or right (201, 202), are aligned so as to slide the sleepers (191, 192). and (201, 202) on each other to obtain varying lengths. Advantageously, its sleepers are provided with fixing holes (21) to consolidate the assembly. These means have the advantage of incorporating in the frame sleepers adjustable lengths to adjust the width of the frame depending on the size of the bed. The chassis is therefore adaptable to all standard sizes of bed bases.
    In some embodiments, legs (23) are mounted on the sleepers, preferably at their ends. Advantageously the feet have the height adapted to be placed on the ground when the system is in the low position. These means stabilize the bed base in the low position and allow to remove the feet of the bed frame and make the frame structure freestanding.
    The present application describes various technical features and advantages with reference to the figures and / or various embodiments. Those skilled in the art will appreciate that the technical features of a given embodiment may in fact be combined with features of another embodiment unless the reverse is explicitly mentioned or it is evident that these characteristics are incompatible or that the combination does not provide a solution to at least one of the technical problems mentioned in this application.
