Definitions

  • the present invention relates to a slatted base including a device for changing the firmness of the seat area of a slatted base.
  • slatted bed bases including in particular a articulated part with slats which can be raised horizontal position at a maximum raised position of way to build a file.
  • Such a box spring gives complete satisfaction from the point of view comfort when the liftable part is in position horizontal, but as this part is raised appears a feeling of discomfort in the seating area defined by the backrest part of the causes the slats in this seating area to sink more and more under the weight of the user of the box spring.
  • US-A-2,485,199 describes a box spring comprising at each corner of it an elastic spring and lever unit allowing to exercise a more or less important firmness depending on the load applied to a bar plate elastic supported by elastic units.
  • This known box spring is very complex and expensive and does not not solve the above problem in bed bases of the type with lifting part forming a backrest.
  • US-A-4,589,151 describes a slatted base comprising a hinged frame with slats whose number, spacing and elasticity can be controlled depending on the body weight distribution of the person to whom the box spring is intended.
  • the object of the present invention is to eliminate the disadvantages above by proposing a slatted base comprising the features of claim 1.
  • the rigid plate-shaped part is moved in a direction perpendicular to the plane of the frame of the box spring in synchronism with the pivoting of the liftable part forming a backrest so that this last occupies its lower position in the stowed position within the framework of the lifting part and its upper position in maximum raised position of the liftable part.
  • the rigid plate-shaped part is movement controlled by the electric motor by through mechanical means of movement.
  • Mechanical means of moving the rigid part plate-shaped include two parallel bars rotatably mounted as part of the box spring transversely to it and coupled to the shaft electric motor motor so as to be jointly rotated; and at least two elements forming a cam respectively integral with the two bars rotating and located below the rigid part in shape of a plate so as to move it perpendicular to the rotary bars when in jointly driven by the motor shaft.
  • Means for coupling rotary bars to the shaft engine include two pairs of rods including each a connecting rod of the two bars rotary and a connecting rod of one of the bars rotatable to the motor shaft via an arm lever secured to the motor shaft.
  • Each connecting rod of the two rotary bars is connected to these by means of lever arms.
  • each rotary bar carries two elements forming cam.
  • Each cam element is produced from a metal plate fixed perpendicular to the bar corresponding support rotary.
  • the rigid plate-shaped part is displacement guided relative to rotary bars by two pairs guide tabs integral with the rigid part perpendicular to it and engaged respectively on the two rotary bars crossing holes oblong guide tabs.
  • the pairs of rods, the pairs of elements forming cam and pairs of guide tabs are arranged symmetrically to the longitudinal axis of the box spring frame.
  • the rigid part is a rectangular metal plate padded or padded.
  • Figure 1 is a schematic side view of a box spring slatted with partial tearing representing the firmness change device according to the invention.
  • Figure 2 is a perspective view from below of box spring according to arrow II in FIG. 1 and representing the firmness change device in low position.
  • Figure 3 is a view similar to that of Figure 2 representing the firmness change device in high position of maximum firmness.
  • Figure 4 is a sectional view along line IV-IV in Figure 2.
  • Figure 5 is a sectional view along the line V-V of Figure 3.
  • Figure 6 is a sectional view along line VI-VI in Figure 2.
  • Figure 7 is a perspective view along the arrow VII of figure 2.
  • reference 1 designates a bed base of the type with transverse slats 2 arranged transversely to the wooden frame 3 of the box spring which includes a lifting part 4 consisting of a frame metallic bearing transverse slats 2 and capable of occupy a horizontal stowed position in frame 3 box spring and several tilted raised positions selectively adjustable by the user so as to compile a file.
  • the movement of the lifting part 4 is controlled by an electric motor 5 fixed in frame 3 of the box spring to one of the side members 6 thereof.
  • the electric motor 5 is activated by manual control (not shown) connected to it by an electric cord.
  • Engine electric 5 has its motor shaft 7, arranged transversely between the side members 6 of the frame 3 of the box spring, which is mechanically coupled to the part liftable 4 by side arms 8 allowing the pivoting around the axis defined by the motor shaft 7 of the lifting part 4.
  • the firmness of the seating area of the slats 2 defined by part 4 occupying a position record forming is automatically changed to depending on the pivoting of the lifting part 4.
  • the device for changing the firmness of this seating area includes a rigid piece in the form of a plate 9, preferably metallic and rectangular, arranged under the slats 2 of the area seat and can be moved in a guided way relative to frame 3 of the box spring between a position lower shown in Figures 2 and 4 to which the slats 2 of the seating area can wrestle freely under the person's weight and position upper shown in Figures 3 and 5 limiting the slat travel 2 to a value corresponding to a maximum firmness of the seating area.
  • the slats 2 of the seating area provide the reclining user on the box spring, via a mattress, the feeling of comfort usual because the weight exerted on this area by the user's buttocks are not very high.
  • the rigid part 9 approaches the slats 2 of the seating area so as to limit the deflection of its slats and to prevent the weight of increasingly important user focusing on the buttock area of the latter crushes the slats.
  • the displacement of the rigid plate-shaped part 9, in a direction perpendicular to the plane of the frame 3 of the bed base 1, is controlled by the electric motor 5 whose motor shaft 7 is coupled to the rigid part 9 by mechanical means of displacement thereof.
  • These mechanical means include two rigid bars metallic and parallel 10, 11 rotatably mounted in the frame 3 transversely to the side members 6 thereof and coupled to the motor shaft 7 so as to be jointly rotated in the same direction; and two pairs of cam members 12; 13 in solidarity respectively of the two rotary bars 10; 11 and located below the rigid part 9 so as to move it perpendicular to the bars rotary 10, 11 when jointly driven by the drive shaft 7.
  • Each cam element 12, 13 is made from a fixed metal plate perpendicular to the rotating support bar corresponding 10, 11.
  • Each bar 10, 11 has each of its tubular end parts rotatably mounted on a cylindrical axis 14 fixed perpendicular to the beam corresponding 6, for example by a fixing screw 15.
  • the means for coupling the rotary bars 10, 11 to the drive shaft 7 include two pairs of rods 15, 16 each comprising a twinning link 17 of the two bars 10, 11 and connected to these bars by through two lever arms 18 and one connecting rod 19 for connecting the rotary bar 10 to the shaft motor 7 by means of a lever arm 20 secured to the drive shaft 7.
  • Each link 19 is connected to the rotary bar 10 by the lever arm 18 of connection of bar 10 to rod 17.
  • each hinge pin 21 connecting a lever arm 20 to the link corresponding 19 is housed in a light or hole oblong 22 made at the end of the link 19 and allowing the electric motor 5, when the part rigid plate-shaped 9 is in the low position, to have enough power to lift the workpiece rigid 9.
  • the oblong holes 22 introduce a delay in lifting the plate 9 and allowing not increase the firmness of the seat area too quickly if you only lift your head slightly and not overload the motor during the start of lifting phase of the head or torso, the phase where the motor is most solicited from the power point of view.
  • the pairs of rods 15, 16, the pairs of elements forming cam 12, 13 and pairs of guide tabs 23, 24 are arranged symmetrically to the longitudinal axis of frame 3 of box spring 1.
  • the descent of the rigid shaped piece of plate 9 is carried out by controlling the electric motor 5 so as to move the cam elements 12, 13 in the opposite direction to that indicated by the arrows of Figure 4, the downward movement of the rigid part 9 effected by gravity or under the weight of the user.
  • the weight of the user which is maximum when the latter is seated with the part 4 raised to maximum position, is effectively supported practically by the two rigid metal bars 10, 11.
  • the slats 2 of the seating area are practically in contact with it which is preferably padded or padded.
  • the movement of the rigid plate-shaped part can also be driven by an electric motor independent possibly synchronized with the lifting the lifting part forming the backrest.
  • the invention thus makes it possible to obtain a gluteal region of the flexible and comfortable box spring when lying down and gluteal area closed by change in firmness in position seated.
