Definitions

  • the invention refers to an articulated liftable bed.
  • Articulated beds with lifting mechanisms are known that allow to lift and maintain the net (or slates) of the bed (i.e. the so-called bedspring ) at a certain height from the ground, thereby allowing housewives to make the bed comfortably without bending and to have access to the space underneath the net.
  • EP2160961 shows an example of such a bed with a bedspring liftable via an electric motor.
  • the bedspring is hinged to a rectangular basal big-drawer (also called container ) that delimits a closed volume for use as a storage space.
  • container also called container
  • a common problem of these beds is how to clean under the container and/or under the objects it contains.
  • mechanisms that lift the container have been invented, but they are bulky, expensive and require muscular effort or additional drive means. And the objects inside the container must be moved by hand.
  • US 907 342 describes a box-couch with a liftable tray.
  • the main object of the invention is to improve this state of art.
  • Another object is to solve or mitigate the above problem and/or to propose a liftable bed with more features.
  • a first advantage of the bed is that the mechanics or the drives to be used must not be complicated or expensive, for example staying the same as a pre-existing motorized bed.
  • a second advantage is to exploit the bedspring's inclination to raise the support for objects to a height that is both comfortable for the user and sufficient to allow the cleaning of the inside.
  • a linear upward lifting of the platform involves not only some mechanics for reaching the required height, also having to compensate for the thickness of the object-holder which during cleaning of the hollow base container would in fact be an obstacle, but also a greater height for the whole platform.
  • a tiltable platform on the other hand, always maintains a side of its own either near or inside the hollow base container, so the articulation connecting it to the base hollow container is less stressed, while the opposite side gets up a lot.
  • Another aspect of the invention relates to a method as defined in claim 12 for accessorizing a bed comprising a base hollow container and a flat platform tiltable relative to the container, wherein a support for objects is arranged inside the base container so that it can be raised with respect to the base container for remaining stably in a raised position, wherein the support for objects is connected or connectable only to the platform for being liftable together with it.
  • Another aspect relates to a method for producing a bed provided with a hollow base container and a flat platform tiltable with respect to the container, wherein a support for objects is mounted inside the base container so that it can be lifted with respect to the base container to stay steadily in a raised position, and the support for objects is connected or can be connected only to the platform to be liftable together with it.
  • Another aspect relates to a method for providing a bed, which comprises a hollow base container and a flat platform tiltable with respect of the container, with a support for objects, wherein the support is placed in the base container so that it can be raised with respect to the base container to remain stably in a raised position, and the support for objects is connected or can be connected only to the platform to be lifted together with it.
  • the object support is connected or can be connected only to the platform to be lifted together with it.
  • the support for objects is hanged solely to the platform.
  • the lifting device may e.g. consist of
  • the components of the lifting device are minimized and the platform movement is exploited to lift the support for objects.
  • the support for objects in such a way that it can be lifted together with the platform.
  • the support is mounted under the platform so that it can be lifted together with the platform.
  • the hollow base container serves as a storage room and preferably:
  • the hollow base container no longer has to necessarily have a bottom that covers all of its plan (condition needed before so that the contained objects would not touch the ground or would not disperse).
  • said support stays housed inside the base container and keeps the objects together and separated from the floor, and it can raise them grouped. Therefore, cleaning operations are facilitated and the bottom of the hollow base container can be absent or reduced to a minimum, its vertical side walls being enough.
  • platform it is meant a rigid plane, like also for example a bedspring, capable of supporting a mattress or at least a supine person.
  • the platform's dimensions can be variable, e.g. single or double.
  • the platform preferably
  • the support for objects can be produced in many variants, e.g. comprising or consisting of a horizontal or oblique rod, and/or a box and/or a shelf and/or a drawer and/or a bowl and/or a net basket and/or a tray and/or a case and/or a container (to distinguish the latter from the base container we will call it liftable container ).
  • the rod serves for example as a coat rack, while the liftable container or the shelf constitute a compartment of the bed wherein to store objects like clothes and accessories.
  • the support for objects may be permanently connected to the platform, becoming an integrated part of the bed, or non-permanently, if it is configured as a bed accessory to be attached to or detached from the platform if necessary.
  • the support for objects is said to be connected only to the platform to be lifted together with it.
  • the support is connected only to the platform and in such a way to remain hanged below the platform at a certain distance from it, so that the support gets concealed inside the inner volume of the container when the platform is lowered and horizontal, while it rises to "eye level" when the platform is tilted or raised remaining horizontal. Since the support can be lifted with all the objects it contains or supports, it is no longer necessary to remove them from the container during cleaning.
  • connection between the support for objects and the platform is open to many variants.
  • the connection may comprise
  • the platform can be raisable and tiltable with respect to the base container.
  • the support is connected to the platform so that it remains suspended only below the portion of the platform that upon tilting goes higher (so the objects come to a more comfortable level).
  • the area covered horizontally by the support is about half that of the platform.
  • the bed comprises an electric motor or actuator to move and/or tilt the platform, so as to reduce to zero the user's effort, who does not have to lift the weight of the objects.
  • the bed comprises an electric motor or actuator for moving and/or tilting the platform, the electric motor or actuator cooperating with an articulated quadrilateral that supports the platform.
  • the articulated quadrilateral preferably comprises two rigid, unextendable members, of different length, hinged at one end to the base container and at the other end to the platform.
  • the bed comprises two electric motors or actuators for moving and/or tilting the platform, an electric motor or actuator constituting a side of an articulated parallelogram that supports the platform, while the other electric motor or actuator being connected to one side of the articulated parallelogram to raise such side by rotating it relative to a fulcrum located at a lower end of such side.
  • Another variant, of manual type, for moving and/or tilting the platform envisages one or more gas springs hinged between the platform and the hollow base container.
  • the force generated by one or each of the gas springs is adjustable, so as to calibrate them on the weight of the objects, and/or - for the same purpose - one or each of the gas springs has connection points to the platform and/or to the hollow base container that are adjustable in their position.
  • the lifting device or the connection between the support for objects and the platform may comprise an automatic tilting mechanism or system with the function of maintaining horizontal or substantially horizontal the support during the lifting movement or at least in the raised position, irrespective of the platform inclination. So the objects do not overturn or they do not fall from the support (advantageous especially if the support is a shelf or a liftable container).
  • the bed may comprise a system that makes a shortening or an elongation of a suspending cable, and/or a shortening or an elongation of a suspending rigid arm, and/or a rotation of the object-holder support about said hinge, correspond to a variation of the platform's inclination.
  • the hinge axis is preferably parallel to the horizontal rotation axis of the platform about which its lifting movement occurs, or to the axis of its lifting arms.
  • the support for objects may be made in many sizes and shapes, just being enough that it can be housed inside the base container (e.g. a criterion is that the support has a vertical bulk equal to or less than the height (of the side walls) of the container).
  • the support has a width at least equal to half the width of the platform (looking at the platform from the front foot-side of the bed); and/or the support has a depth less than or equal to half length of the platform (looking at the platform from a side of the bed).
  • the bed preferably comprises a second support mounted inside the base container and movable in a direction orthogonal to the rotation axis of the platform or the rotation axis of the lifting arms of the platform.
  • the second support preferably has an area approximately complementary to that of the support, so that the two cover all or most of the area of the base container.
  • the second support is e.g. mounted inside the base container so that it can slide into the area of the base container left clear by the (first) support when the latter is raised together with the platform.
  • the second support can end up under the (first) raised support and the user has comfortably available all the items stored in the container.
  • the rotation axis of the platform's lifting arms is preferably a horizontal axis.
  • the second support is slidably guided inside the base container through, e.g. linear, guides or is sliding on wheels, e.g. sliding directly onto the floor supporting the hollow base container.
  • the support for objects and/or the second support for objects comprises
  • the second support shares all the variants of the first support, mutatis mutandis, and here they are not repeated.
  • One or each aspect of the invention may be expanded if in place of said object-holder support an electronic household appliance, such as a television, a radio, a telephone, a hairdryer, a computer or an appliance, is substituted.
  • an electronic household appliance such as a television, a radio, a telephone, a hairdryer, a computer or an appliance
  • the upward lifting of the platform can occur, as mentioned, either manually or through (preferably electric) actuators.
  • the support for objects can be an accessory that completes a pre-existing liftable bed, such as, for example, that in EP2108288 , an intelligent control is needed for the actuators, to be able to properly control the actuators both when there is the support for objects, and when it is not there.
  • an intelligent control is needed for the actuators, to be able to properly control the actuators both when there is the support for objects, and when it is not there.
  • one can exploit a drive system as in EP2160961 which allows to lift the platform relative to the hollow base container when the platform is in a position maximally close to the hollow base container.
  • a variant of the invention then solves the problem of how to properly control the actuators to allow the use of the lifting device both when the support for objects is installed in the bed, and when it is not.
  • the articulated parallelogram of the mechanism therefore has an extensible side, the one constituted of the first linear actuator.
  • the mechanism then allows the platform to be raised to a certain height from the ground relative to the container in two ways or with two trajectories:
  • activation of the first and second actuators we intend their extension.
  • the term “mainly” means that in some cases, although an actuator is the main responsible of the lifting movement, it is also necessary to briefly activate the other, e.g. to get out of a position of mechanical stall or to slightly modify the shape of the articulated quadrilateral or parallelogram in order to limit the internal stresses thereinto.
  • the stroke of the briefly activated actuator is much lower than, for example less than 1/5 or 1/10 of, that of the mainly activated actuator.
  • the second actuator is preferably a linear actuator such as the first one, but not necessarily. It can be e.g. a rotary electric motor.
  • movement 1) implies for the platform a composite trajectory, given by the sum of a horizontal translation and a vertical translation.
  • an electronic unit e.g. a programmable microprocessor to control and/or program the activation of the actuators.
  • the electronic unit is programmed to drive the actuators with a sequence of steps that accomplishes the aforementioned movements 1) and 2).
  • the electronic unit is programmed for detecting a signal from said sensor, processing said signal to determine the presence of the support for objects within the base container, inhibiting the movement 1) if the presence of the object support inside the base container is determined, i.e. only allowing the movement 2) (if necessary - for maximum safety - bypassing external commands from a user).
  • the platform returns to its lowered position, maximally close to the base, with a reverse sequence of running the actuators.
  • the bed comprises an (optional) user interface that is connected to the electronic unit and through which a user can send drive commands to the electronic unit for the actuators.
  • the user interface allows the user to command the start of movements 1) or 2) (or the inverse movements to bring back the platform lowered down on the base container). If the user carelessly pressed, for example. a button to command the beginning of movement 1) in a bed with an installed support for objects, without the constraint imposed by the electronic unit the bed would be damaged during the movement.
  • the senor works without manual intervention or at least so that the user does not have to worry about it.
  • the senor is installed on one or each connecting element that non-permanently connects the support to the platform.
  • the sensor is a weight sensor or a presence sensor for the support.
  • the senor is installed on the platform at the coupling points between one or each said connecting element and the platform.
  • the sensor can be realized in many ways. It may be e.g.:
  • the senor is e.g. an electric switch or micro-switch operable by a user when the support for objects is installed in the bed.
  • the bed comprises an electronic unit, and a member movable between two positions that is
  • the electronic unit controlling the movable member is the same which controls the platform's actuators.
  • the electronic unit is preferably programmed for driving the movable member so that it moves to the first position, and then activating only or mainly the first actuator to tilt the platform without lifting it vertically.
  • the user interface comprises an element (e.g. a button) for sending a signal to the electronic unit in order to command it to execute the displacement of the movable member from one position to the other.
  • an element e.g. a button
  • the movable member comprises, for example, a rotatable hook, a pin movable back and forth, an openable and lockable clamp, a hook or a piece movable between two positions.
  • the said movable member is replaceable with a generic electrically controlled engaging element, not necessarily movable, such as an electromagnet.

  • a bed MC comprises a fixed box-like frame 10 and a bed-plane 20 which can tilt with respect to the frame 10 ( Figures 3 and 4 ).
  • the frame 10 is usually square or rectangular, and is formed by a front vertical wall 10b, two vertical side walls 10a, 10c, and a vertical rear wall 10d which delimit an inner empty compartment V useful to contain objects.
  • the frame 10 has a bottom wall.
  • the bed-plane 20 is a platform or a support surface for example for a mattress or a supine person.

  • a single mechanism will be described for simplicity.
  • the mechanism (or each guided lifting group) comprises a plate 30 fixed internally on a vertical wall of the frame 10.
  • To the plate 30 are hinged the ends of two rigid lifting arms 40, 50 (e.g. two rods), in turn hinged, at the other end, to the plane 20, preferably by means of an angular bracket 70 which allows an easier mating between them.
  • the arms 40, 50 have different lengths and form altogether, along with the frame 10 and the plane 20, an articulated quadrilateral capable of guiding the bed-plane 20 to tilt it relative to the frame 10.
  • Figures 2-4 show the sequence of tilting.
  • the arms 40, 50 have hinging axes which are all horizontal and parallel to each other.
  • the rotation of the bed-plane 20 is assisted by an electric linear actuator 60 having a linearly movable piston 62.
  • the actuator is mounted near the arms 40, 50 and so as to push from below the bed-plane 20 when the piston 62 extends.
  • the invention is also applicable to beds whose bedspring is not only tiltable, therefore also to beds with a bedspring which tilts and is lifted remaining horizontal like e.g. those in EP2160961 or EP2108288 or EP2387914 .

  • the object-holder 80 has the shape of a shelf having a bottom 82 from which two opposite side walls 84 and a rear wall 86 elevate.
  • the object-holder 80 moves along with the bed-plane 20, so when the bed-plane 20 is lowered ( Figure 2 ), the holder 80 remains inside the frame 10, while when the bed-plane 20 is raised ( Figure 4 ) the object holder 80 arrives at a raised position where the user can comfortably reach the objects.
  • the (bottom 82 of the) holder 80 is preferably maintained horizontal during the lifting movement or at least in the raised position, so as not to disorganize the objects.
  • the object-holder 80 may have the end closest to the center of the bed-plane 20 hinged to the bed-plane 20 about a horizontal axis X (parallel to the plane of the bed-plane 20) so that it can swing around such axis X.

  • one end of the suspension cable 94 is fixed to the object-holder 80, from which the suspension cable 94 runs down the bottom of the bed-plane 20 where it is diverted along the bed-plane 10 up to a pulley 200, fixed on the frame 10. From the pulley 200 the suspension cable 94 continues to another pulley 220, integral to the bed-plane 20, from which it is diverted toward a fixed point 222.
  • the pulley 220 modifies the path of the suspension wire 94 as a function of its inclination. Particularly, when the bed-plane 20 is lowered, the pulley 220 presses on the cable 94 and increases the dimension of a bend thereof, with the result of increasing the tension on the cable 94 and, therefore, the segment of cable 94, which supports the object holder 80, shortens, thereby pulling the object holder 80 toward the bed-plane 10. During lifting of the bed-plane 20, the opposite occurs.
