Definitions

  • the present invention relates to a device serving as a mezzanine retractable bed comprising a frame equipped with a frame, a retraction mechanism for retracting the bed frame from a first use position to a second storage position .
  • the furniture can be used in a first position to then be transformed into its second position to free space.
  • the furniture can be used as bed during the night to be transformed during the day to have more space in the room.
  • the document FR 2 729 062 describes in particular a retractable bed composed of a frame, a frame and a mechanism for positioning the horizontal frame at several positions in height, the bed can thus be used or stored.
  • the retraction mechanism used in this case operates using electric drive means comprising in particular a motor.
  • US 3,745,595 discloses a retractable berth intended in particular to serve as sleeping space in a camper, on a boat or for other similar uses.
  • This device has a frame fixed for example to the ceiling of a camper, a frame receiving a mattress and a retraction mechanism for retracting the frame from a position of use to a storage position.
  • the retraction mechanism operates mechanically and has axes positioned on the frame, each of these axes being connected by connecting rods to the frame.
  • the object of the present invention is to provide a device tending to obviate the aforementioned drawbacks of current systems.
  • the present invention relates to a device serving as a mezzanine retractable bed comprising the features set forth in claim 1.
  • the mechanism of retraction of the device comprises two axes positioned on a bed frame, each of these axes being connected by a connecting rod to a pivot on a frame, in order to connect the frame and the frame, and a synchronization mechanism of the movement connecting these two axes and imposing a synchronized rotation of the two axes.
  • the movement synchronization mechanism comprises a first element extending radially from each axis of the frame and at least one second element kinematically connecting the first elements at their outer ends, in order to stabilize the synchronized movement of the axes.
  • the retraction mechanism comprises at least one rod on each axis, these rods being articulated on arms to form a deformable parallelogram imposing a synchronized rotation of the two axes.
  • the mechanism is arranged, reducing the number of parts and optimizing their location, efficiently and simply to reduce production costs and maintenance. It can be easily installed inside a box integrated naturally in the frame supporting the bed base in order to have an aesthetically attractive presentation of the furniture.
  • the mechanism may comprise at least one sector and a lever or two sectors positioned on the axes, the latter being connected by one or more springs.
  • the spring provides a force facilitating the movement of a frame position to another.
  • the transformable furniture according to the present invention can serve as a bed in its use position and allows to easily release space in its storage position, for example to use a desk, a table or desk. other things installed under the bed frame.
  • the retractable bed according to the present invention is an independent assembly constituting a mezzanine retractable.
  • This mezzanine consists of a frame 10 formed of four vertical posts 11 connected together by a rigid structure 12, 13, 14, for example triangulated, ensuring the stability and rigidity of the assembly.
  • This frame 10 serves as a support for a horizontal frame 20 normally formed of two longitudinal boxes 21 connected by two transverse boards 22, as indicated in FIG. figure 2 where the faces of the boxes 21 hiding in this view the retraction mechanism are not shown.
  • the frame 20 could also be formed by two transverse boxes connected by two longitudinal boards, modifying the location of the retraction mechanisms accordingly, as will be apparent from the following explanations.
  • the frame 20 could be formed by a box and a corresponding beam replacing the second box, these two parts being again connected by two boards.
  • Each box 21 of the frame 20 contains a retraction mechanism 30 having two axes 31, as shown in FIG. figure 3 where the inner or inner inner face of the boxes is not shown to show the details of the mechanism 30.
  • An axis 31 of a retraction mechanism 30 can physically traverse the entire frame 20 by connecting two retraction mechanisms 30 in the caissons 21 located on each side of the frame 20 or may have only the length corresponding to the thickness of a box 21.
  • at least one of the two axes 31 of a retraction mechanism 30 passes through the frame 20 as shown in figure 3 .
  • Each of these axes 31 is connected at its outer ends by a connecting rod 32 to a pivot 33 that comprises each post 11 of the frame 10.
  • the location of the pivot 33 in the posts 11 and the length of the connecting rods 32 are chosen so as to what, on the one hand, the position of storage of the frame 20 frees enough space to use the space below this frame 20 and that, on the other hand, the position of use of the bed and in particular the frame 20 is at a suitable height.
  • the device can also be equipped with a ladder 23 allowing the user to climb into the bed without any effort, as shown in FIG. figure 1b .
  • Each axis 31 of the retraction mechanism 30 of each box 21 carries at least one link 34, the ends of the two links 34 of the two axes 31 being articulated on the arms 35 to form a deformable parallelogram imposing a synchronized rotation of the two axes 31.
  • two opposite sides, longitudinal or transverse, of the frame 20 are equipped with a retraction mechanism 30, that is to say that the arms 35 are thus in two boxes 21 located on two opposite sides of the frame. 20.
  • the second box may be replaced by a simple beam, as mentioned above, this beam having only a pivot 33 connected by a connecting rod 32 to the axis 31 instead of a complete retraction mechanism.
  • the retraction system of a frame 20 has two retraction mechanisms 30 and is therefore symmetrical.
  • the rods 34 are preferably mounted perpendicular to the corresponding rod 32, as illustrated in FIG. figure 3 , and the arms 35 comprise, at each of their ends, an arcuate portion rounding the corners of the deformable parallelogram so as to allow the arms 35 to be brought as close as possible into the horizontal position of the link 34, ie in the position storage 20a and 20b use of the frame 20, wherein the hinge connections between the rods 34 and the arms 35 must find room between the two arms 35 corresponding.
  • This set of rods 34 and arms 35 form a mechanism for synchronizing the movement of the axes 31.
  • a variant among several others, not shown, to the preceding solution to form such a motion synchronization mechanism comprises at least one pinion on each axis 31, these pinions being connected by a chain to form a kinematic connection imposing a synchronized rotation of the two axes 31. It is obvious that the pinion and chain assembly is equivalent to the mechanism using rods 34 and arms 35, and the remarks of the preceding paragraph apply analogously to this solution.
  • the synchronization mechanism of the movement which is positioned on the axes 31 and connects these two axes 31 by imposing a synchronized rotation of the two axes 31 is part of the retraction mechanism 30 and can thus be realized differently.
  • Each axis 31 of the retraction mechanism 30 of each box 21 may still carry at least one sector 36, the two sectors 36 of a mechanism 30 being connected by one or more springs 37.
  • the force of the springs 37 assists in the ascent and dampens the downward movement of the frame 20.
  • the force of the springs 37 can be adjusted via the aforementioned sectors 36 because the springs 37 or corresponding intermediate links, for example a wire 371 between a sector 36 and a spring 37, can be hung in several places along the outer periphery of each sector 36 thus putting the springs 37 under a greater or lesser tension and simultaneously changing the angle of attack of a spring.
  • One or even both sectors 36 can also be replaced by a simple lever limiting or even eliminating the possibility of varying the torque exerted by the springs 37 on the sectors 36.
  • This set of sectors and springs therefore plays the role of a driving device for the retraction mechanism to facilitate the movement of the frame by the user.
  • this provision could be replaced for example by spiral springs mounted individually on the axes 31.
  • FIG. 4a to 4c show in detail one of the possible embodiments of such a sector 36 on which is engaged a wire 371 connecting it to the corresponding spring 37.
  • this sector 36 Along the outer periphery of this sector 36 are arranged several holes 361 to introduce a stop pin 362 on which is fixed the aforementioned wire 371, this being shown in FIG. figure 4a .
  • the tension on the spring 37 and its angle of attack relative to the sector 36 can be adjusted.
  • orifices 211 are provided in the inner planks of the boxes 21 of a frame 20, for example in front of the holes 361 of the sector 36, the frame 20 being in the storage position 20a. These orifices 211 and the pins 362 and 363 are illustrated in the figure 4c , the extension pin 363 being shown in its disengaged position and in the engaged position.
  • the shafts 31 are mounted idly in the frame 20, for example by means of bearings or simple openings, the connecting rods 32, the links 34 and if necessary, the sectors 36 are fixed rigidly relative to each other and preferably also to these axes 31.
  • the axes 31 can also be fixed to the frame 31.
  • the connecting rods 32, the rods 34 and the where appropriate, the sectors 36 are fixed rigidly relative to one another and the axes 31 are idler pivoted on this assembly.
  • the pivots 33 which are pivotally mounted either in the rods 32 or in the posts 11 (or both).
  • the device may further comprise a locking device for locking the frame 20 in at least one of its extreme positions.
  • This locking device can be integrated in the axes 31, as illustrated in FIGS. Figures 5a and 5b .
  • an axis 31 of a retraction mechanism is for this purpose formed by a tube of a length corresponding approximately to the thickness of a box 21 and pivotally mounted in the frame 20 forming a rigid assembly with the rod 32, the rod 34 and, where appropriate, the sector 36.
  • a cylindrical body 311 a tube or a cylinder, a slightly longer than the axis 31.
  • the body 311 is bevelled at the outer end facing the post 11 of the frame 10 and has a pin 312 at the inner end.
  • a guide 313 having grooves receiving the pin 312 of the body 311 is fixed to the frame 20 so as to constrain the movement of the body 311 in the axis 31 forwards and backwards while simultaneously preventing its rotation.
  • At least one spring 314 pushes the body 311 outwards, the latter being able to retract inside the frame 20 when its outer end cut bevel touches the post 11.
  • the latter is equipped with at least a stop, for example in the form of a striker 111 formed in the post opposite the positions where the body 311 comes in the low and / or high position of the frame 20. Under the effect of the force of the spring or springs 314, the body 311 can snap into the striker 111 in the post, thus locking the frame 20 in its storage position at the top or the use position at the bottom.
  • the frame 20 can be unlocked again.
  • the locking device can also be placed elsewhere in the box 21, instead of being placed in the axis 31, while remaining able to cooperate with the frame 10.
  • this locking device can be provided for example in the front part of the bed, preferably on each side, the front axis is therefore physically in two parts, while the rear axis of the bed can be in one piece to serve to better synchronize the movement the frame physically connecting the two retraction mechanisms 30 housed in two boxes 21 on each side of the frame 20.
  • a damping device 38 may be provided on the frame 20 or on the frame 10. As shown in FIG. figure 5a , this damping device 38 may be constituted by a hydraulic stop positioned inside a box 21 so that it cooperates with the retraction mechanism 30, for example a sector 36, to dampen the frame 20 may be constituted by a spring, a rubber or any other means capable of fulfilling this damping function, and the cooperation could be done with the rod 34, the connecting rod 32 or another part of the retraction mechanism 30.
  • FIG. 6a shows the frame 20 in the upper position, that is to say in the storage position 20a.
  • the frame 20 moves, while remaining horizontal, forwards and downwards, the intermediate positions of the frame 20 being illustrated in FIGS. Figures 6b and 6c , then backward and downward, see the figure 6d , to finish its displacement in the low position of use 20b illustrated in FIG. figure 6e .
  • the frame is locked again if it is equipped with the locking device described above.
  • the springs 37 tend to compensate for the weight of the frame 20 and allow easy and smooth movement.
  • the force exerted by the springs 37 increases from the storage position 20a to become maximum in the intermediate position of the figure 6d and then decrease slightly to the use position 20b. She can be adjusted using the aforementioned sectors 36 and pins 362, 363, forming a mechanism for adjusting the force of the springs 37.
  • the damping device makes it possible to damp the movement of the frame 20 driven by the force of the springs 37, for example applying to the sectors 36 of the retraction mechanism 30, as illustrated in FIG. figure 6a .
  • the frame 20 can serve as a support for a bed base and a mattress to form a mezzanine retractable.
