Definitions

  • the present invention relates to a convertible bench of the perpendicular coating type.
  • a convertible sofa bed perpendicular is also called sofa, sofa bed or sofa bed type "BZ".
  • the document FR 2,743,275 discloses a motorized seat in which the actuating system comprises a rotary motor driving in rotation a pinion cooperating with a chain link whose free end is coupled to the front panel.
  • the actuating system comprises a rotary motor driving in rotation a pinion cooperating with a chain link whose free end is coupled to the front panel.
  • Such a solution is however unsuitable for use in housing, because the system with pinion and chain is a source of noise, sometimes with leakage of the lubricant necessary for the proper gearing between the pinion and the chain, not to mention the complexity and the costs induced by the chain which must measure at least one meter fifty centimeters.
  • the document DE 935 275 also discloses a motorized seat in which the actuating system comprises a rotary motor driving a pinion in rotation, via a transmission belt, wherein the pinion is in mesh with a toothed sector mounted on the rear panel.
  • This system with belt, pinion and toothed sector has the same disadvantages as for the bench of the FR 2,743,275 , namely noise, lubricant leaks, complexity and cost.
  • the document FR 2,614,773 discloses another motorized seat in which the actuation system comprises an electric winch which winds and unrolls cables attached to the front and rear ends of the front panel.
  • This system with winch and cable has several disadvantages in terms of noise, safety and cost, not to mention the complexity to manage the cable windings.
  • the document WO 01/60212 discloses another convertible bench of the perpendicular coating type, employing a double cylinder system and a single cylinder system for the folding / unfolding of the bench.
  • this tray has a complex foldable structure, implementing a first pivoting frame hinged to the frame and a second frame hinged to the first frame, leading to a complex kinematics that requires the use of three jacks, generating prohibitive costs.
  • this bench uses a central wheel intended to roll on a rail secured to the frame to prevent tilting of the frame.
  • this simple roulette solution has the disadvantage that the wheel rolls on a rail much too short, so that this wheel causes a support on the rail on a particularly short race, thus not preventing the frame from sliding on the ground during the folding / unfolding phases, except that the frame is sufficiently heavy.
  • the present invention aims to solve all or part of these disadvantages by providing a convertible bench of the perpendicular coating type which is equipped with an actuating system of simple and inexpensive design, and quiet use and leak-free of lubricant.
  • Another object of the present invention is to allow the fixed structure to remain in place on the floor, without slipping, during the folding / unfolding phases, even if this fixed structure is light.
  • the invention proposes to motorize the seat by means of a motorized cylinder which provides a motorized folding / unfolding and therefore effortless for the user, the motorized cylinder being advantageously controllable by means of a wired remote control or wireless.
  • the bench further comprises support means of the foldable structure on the fixed structure, said support means ensuring a support of the foldable structure on the fixed structure in the bench configuration, and said means of support being shaped to maintain a sliding or rolling support between the foldable structure and the fixed structure along the longitudinal direction along at least one longitudinal element of the fixed structure and / or the foldable structure in order, on the one hand, to maintain supporting the foldable structure on the fixed structure during part of the folding / unfolding and, secondly, guiding the foldable structure of the coating configuration to the bench seat configuration.
  • These support means thus have a dual function, with a first function of stabilizing the bench on the ground, and more particularly to immobilize it on the ground during the folding / unfolding movements, thanks to a support of the foldable structure on the structure fixed at the start of the seat configuration (in the direction of unfolding) or at the finish in the seat configuration (in the direction of folding). Indeed, these two situations of departure and arrival can be critical in terms of weight transfer, because the cylinder can both move the fixed structure (if it is not anchored or weighted on the ground) that the foldable structure .
  • These support means are designed so that the foldable structure is supported on the fixed structure, while following the movement of folding or unfolding (thanks to these rolling or sliding bearings), and thus keep the fixed structure in place on the ground. In this way, the jack displaces only the foldable structure, with the fixed structure which is immobilized by means of support.
  • the second function is to guide the foldable structure, essentially from the bench seat configuration (in the unfolding direction). Indeed, as the unfolding is motorized and nobody does not pull on the structure (as is customary with a non-motorized convertible seat), it is important that the front panel is driven or guided in longitudinal translation forwards and, thanks to the rolling or sliding support means a guide in longitudinal translation is carried out which will enable this guidance to be carried out.
  • the cylinder rod moves the foldable structure in a folding / unfolding movement, and thus the rod and the cylinder body undergo the reaction of the foldable structure (weight, resistance to rotation). level of joints and weight transfers between panels), at the risk of moving the fixed structure on the ground.
  • the support means therefore make it possible to transfer the weight of the moving panels to the fixed support, thus ensuring the plating and the immobilization of the fixed support on the ground; the sliding or rolling supports of the support piece or pieces ensuring a sustained support during the movement of the panels and thus the aforementioned guidance.
  • the sliding or rolling support is achieved by means of this (these) part (s) of support, on at least one longitudinal element defining a longitudinally extended contact surface so that the support is maintained for a certain length in the critical periods, starting from the seat configuration (in the direction of unfolding) or arriving in the seat configuration (in the direction of folding).
  • the supports made by the support pieces are distributed between the right and the left, thus balancing the weight transfer of the panels on the fixed support and the guide of the foldable structure in the aforementioned critical periods.
  • the front and rear support pieces slide or roll over almost the entire length of the longitudinal element (of the fixed structure or the foldable structure), which makes it possible to maintain the transfer of the weight of the panels long enough to immobilize. efficiently the fixed support in the aforementioned critical periods.
  • the front and rear support pieces also ensure that weight transfer and guidance of the foldable structure are maintained, even if one of the support pieces leaves contact with the contact surface, the other piece of support would maintain contact to ensure weight transfer and guidance.
  • the front and rear support pieces are also offset from each other in the transverse direction, and the front and rear contact surfaces are also offset from each other in the transverse direction; the advantage of these offsets being to offer distinct contact surfaces and distinct profiles of interest for guiding the foldable structure.
  • the support means are shaped to, in the bench configuration, raise a front side of the front panel, opposite to a rearward hinged side on the central panel, so that said front panel is inclined with respect to the horizontal, and lock said seat in this raised configuration.
  • the support means ensure that, in the bench seat configuration, the front of the seat (the front panel) is raised, so that this seat is slightly inclined relative to the horizontal for reasons of comfort. sitting, and also stability and holding the bench in this configuration.
  • this raised configuration (in other words with raised seat) is locked or mechanically locked, in addition to the blocking intrinsically made by the cylinder, for the sake of obvious mechanical strength.
  • the or each front support piece has dimensions in a vertical direction orthogonal to the longitudinal and transverse directions greater than those of the or each rear support piece, and the or each front contact surface has a locking ramp on which bears the relevant front support piece in the bench configuration to ensure the locking of the seat in this raised configuration.
  • the front wheels are of greater diameter than the rear wheels, to raise the front of the seat in the bench seat configuration.
  • the locking ramp mechanically locks the seat in the bench seat configuration, because the corresponding front support piece should go up the ramp to get out of the bench seat configuration, which is mechanically impossible with the seat raised and with the cylinder stopped.
  • the or each front contact surface has a plate extended longitudinally on one side by the locking ramp and on the other side by a guide ramp designed to guide the relevant front support piece during folding the sleeping configuration to the bench seat configuration.
  • the or each support piece comprises a wheel rotatably mounted about an axis parallel to the hinge pins.
  • the support means constitute support means of the front panel of the foldable structure on the fixed structure.
  • these support means provide rolling or sliding support of the front panel on the fixed structure during the aforementioned critical periods, knowing that the front panel is essentially guided in translation during the folding / unfolding movements which facilitates the realization longitudinal support or rolling or sliding between the front panel and the fixed structure.
  • the support means constitute support means for the central panel of the foldable structure on the fixed structure.
  • This variant is more complex, however, because the central panel moves in a complex movement combining translation and rotation, so that the contact surface or surfaces must have a complex section to ensure the support and guidance of the central panel on the structure fixed.
  • the rear panel is articulated on the fixed structure along an axis of articulation parallel to the hinge pins, and the body of the jack is articulated on the fixed structure or on the rear panel and the end of the rod. is articulated inversely on the back panel or on the fixed structure.
  • the jack acts on the rear panel to control the folding / unfolding movements of the foldable structure.
  • This is the rotation of the rear panel, driven by the cylinder, which is at the origin of all the movements of folding / unfolding of the bench.
  • the support means are therefore particularly important in this case, because the folding / unfolding movement from the rear, and the support means will allow to hunt / guide in translation the front panel to the before (when unfolding), which is convenient because the front panel advances only because the central panel pushes it at their joint joint (the support means avoiding precisely a blockage at this articulation between front panel and central panel ).
  • the rear panel has a frame, and the articulation of the rod or the cylinder body on the rear panel is on a lever arm secured to the frame of the rear panel.
  • the foldable structure is wider (in the direction of the transverse direction) than the fixed structure, so that the support pieces (respectively the contact surfaces) are located on the inside of the foldable structure while, conversely, the contact surfaces (respectively the support parts) are located on the fixed structure, and in particular on the outside of the fixed structure and / or on the top of the fixed structure.
  • the support pieces are mounted on the inside of the foldable structure (in particular on the inside of the front panel) in order to cooperate with contact surfaces provided on the fixed structure.
  • the foldable structure is narrower (in the direction of the transverse direction) than the fixed structure, so that the support pieces (respectively the contact surfaces) are located on the outside of the foldable structure while conversely, the contact surfaces (respectively the support pieces) are located on the fixed structure, and in particular on the inside of the fixed structure and / or on the top of the fixed structure.
  • This variant corresponds in particular to a situation where the fixed structure is composed of two lateral armrests, preferably connected by a transverse bar.
  • the support pieces are mounted on the outside of the foldable structure (especially on the outside of the front panel) to cooperate with contact surfaces provided on the inside of the fixed structure.
  • the lateral beams 20 each have a substantially flat top surface (the top of the side beams 20) which form contact surfaces.
  • the fixed structure 2 also comprises two front supports 25, respectively right and left, fixed on the respective lateral beams 20.
  • Each front support 25 is attached to the front end of the corresponding side beam 20, and each front support 25 is attached to the outer side of the corresponding side beam 20, i.e. the opposite of the inside the frame of the fixed structure.

  • the plate 251 For each support before 25, the plate 251 is surrounded by two ramps respectively before 250 (or guide ramp) and rear 252 (or locking ramp), which are descending relative to the plate 251; in other words, the plate 251 represents the apex of these ramps 250, 252.
  • the bench 1 also comprises a foldable structure 3 comprising hinged panels, namely a front panel 4, a central panel 5 and a rear panel 6.
  • the central panel 5 has two opposite transverse sides (parallel to the transverse beams 21) articulated respectively on the front panel 4 and the rear panel 6 along parallel axes of articulation A, B.

So, and as visible on the figure 6 , the panel frame before 4 can fit on the fixed structure 2 (with the mounting games near) in the bench seat configuration.
  • the front panel 4 also incorporates two front wheels 43 and two rear wheels 44, in particular of the roller skate type, which are rotatably mounted on the lateral beams 40, and more specifically rotatably mounted on the inner or lower sides of the side beams 40, with a front wheel 43 and a rear wheel 44 by lateral beam 40.
