Definitions

  • the present invention relates to a box spring comprising at least one upper batten and one batten lower.
  • two levels of transverse slats in wood are provided in the central area of the box spring intended to normally receive the kidneys and a user's pelvis, that is, the part of the body of the heaviest user.
  • the first level of slats is defined by upper slats and is coplanar with the slats of the other areas of the box spring, when the bed base is flat.
  • the second slat level is defined by slats lower, called reinforcement slats, which are underlying respectively to the upper slats in the central area of the box spring and can come in contact with them.
  • the lower and upper slats are matched using plastic sliders.
  • two firmness adjustment sliders are slidably mounted in the vicinity of both central areas of an upper batten and a batten lower so as to increase or decrease the stiffness of the lower pair of slats and higher, by moving the sliders more or less, and thus increase or decrease the firmness of the area central of the box spring.
  • the range variation in the stiffness of the pair of slats upper and lower is very small due to the firm and constant coupling of two slats by the cursor.
  • the central area of the box spring offers stiffness relatively high whatever the load supported.
  • the present invention aims to provide a arrangement of upper and lower slats, the stiffness is also adjustable, but which for a given setting, offers stiffness progression in load function, and thus more damping progressive load.
  • a box spring comprising at least one upper batten and a lower batten, is characterized in that it comprises a leaf spring curved having ends slidably mounted on one of the upper and lower slats and a vertex located substantially close to each other upper and lower slats.
  • Terms “substantially close to” means in the sense of the invention “a short distance from” or “in contact of”.
  • the leaf spring is a batten curved in noble material, such as wood, in harmony with the slats of the traditional box springs.
  • the spring to blade is a convex slat in the direction of the slat superior.
  • Leaf spring ends then slide against the lower batten and the top of the leaf spring is located substantially below or in contact with the upper batten.
  • the leaf spring is a convex slat towards the slat lower.
  • Leaf spring ends lean on or hang from the upper batten and the top of the leaf spring is located substantially above or in contact with the lower batten.
  • the central regions of the slats upper and lower between their ends may be free at rest, including the case appropriate at the start of the low deflection of the batten higher until contact with said other of upper and lower slats with the top of the arched batten. Then, under increasing load heavy, the upper batten pushes the arched batten to deflect with the ends of it deviating and sliding on said one of the upper slats and lower. So when the load is relatively light, the amortization is relatively flexible, while when the load is heavy, depreciation is gradually hard for ultimately maintain the charge.
  • the stiffness of the arrangement of the three slats according to the invention is thus much more progressive than the arrangement of two slats according to the prior art.
  • the ends of the box spring have slots or orifices through which said one upper and lower slats. Thanks to these slots or holes, the ends of the leaf spring can slide on said one of the upper slats and lower not only during depreciation of a charge, but also when the user want to change the position of the leaf spring on along said one of the upper slats and lower to increase stiffness to one side of the bed base and reduce the stiffness of the other longitudinal side of the box spring.
  • the box spring can be removable of said one of the upper and lower slats without it being removed from the frame of the box spring so as to easily and quickly interchange the leaf spring with another leaf spring having a different stiffness, or position the leaf spring on another blade of the box spring.
  • the bed base comprises at least one other leaf spring, smaller or larger, supported by the aforementioned leaf spring.
  • the bed base comprises at least one other leaf spring, more or less curved than the aforementioned leaf spring, having ends slidingly supported on said one of the slats upper and lower.
  • the summit of the other leaf spring can be located substantially at near said other of the upper slats and lower, or above or below the spring to first mentioned blade.
  • the box spring comprises two upper slats located substantially above of the lower batten, the top or the ends of the leaf spring being located partly below each of the upper slats.
  • the stiffness of the slat arrangements lower and upper may be different in the same area of the box spring, or between areas different. More generally, when the box spring includes at least two upper slats respectively below two lower slats, two leaf springs are provided which are mounted respectively between the upper slats and the lower slats, which have stiffness different resulting from characteristics dimensional and / or mechanical differences between leaf springs.
  • an arrangement of slats for box spring includes an upper slat 1 and a lower slat 2 extending one above on the other transversely between two long sections 3 of the box spring frame.
  • the upper slat 1 again called “comfort batten”
  • the lower batten 2 also called “batten” reinforcement “or” counter-batten ", is at rest substantially straight, or upwardly convex.
  • the upper batten is thus more flexible than the batten lower.
  • each of the two fastening means 40 includes a single cushioning piece 40, called a ball joint, made of elastomer which has two lower holes for trunnions to be fixed in the underside of the respective long pan 3.
  • Two holes overlapping oblongs 41 and 42 are provided in the room damping 40 to plug in by force ends of the lower and upper slats 1 and 2.
  • Part 40 has other holes in part lower and upper and laterally so that the part 40 can be compressed and pivoted towards the front and back of the box spring along the long side respective 3.
  • each of the two fastening means includes a shock absorber connecting piece 43, called a ball joint, and a fixing support 44.
  • a shock absorber connecting piece 43 called a ball joint
  • Two ends 11 of two neighboring upper slats and parallels 1 in the box spring are coupled to two ends of two lower and parallel slats 2 into the box spring via the shock absorber link 43.
  • Part 43 has four sleeves plastics receiving the ends of the batten and bonded by an elastomer.
  • the connecting piece is embedded pivot about a horizontal axis in the support 44 removably embedded in the face inside of the long pan.
  • a leaf spring under the shape of a small arched batten 5 is interposed in the intermediate space between slats 1 and 2.
  • the batten 5 is curved upwards, i.e. clearly convex towards the upper slat 1.
  • the arrow F of the arched batten 5 is significantly less than the distance D between the slats 1 and 2, so that the upper slat 1 substantially convex is not in contact with the apex 51 of the arched batten 5.
  • the arched batten 5 according to the illustrated example is substantially in arc of circle, the portion of the lower slat 2 underlying to the arched batten constituting the cord C of the arc of a circle.
  • the batten 5 is curved in an elliptical or parabolic arc, preferably vertically symmetrical in order to balance the pressures exerted by the ends 52 of the batten curved 5 on the lower batten 2.
  • the ends 52 of the arched batten 5 form two simple sliding supports on the upper side of the lower batten 2.
  • the ends 52 of the arched batten are notched with two longitudinal slots 53 having a width substantially equal to that of the slat lower 2.
  • the slots 53 constitute sliders crossed and thus guided by the slat lower 2 and have sufficient depth so that the arched batten 5 can flourish in increasing its curvature without the ends 52 becoming release batten 2 when a load is applied to the top 51 of the arched batten 5.
  • the slots 53 are rectangular; according to other variants, the two slides formed by the slot pairs 53 and lower slat 2 can be of circular profile, triangular, trapezoidal or dovetailed, or you.
  • the slots 53 can almost completely frame two sections transverse of the lower batten 2 thanks to two projections 531 located at the ends of the slots of arched batten and underlying the lower batten, this prevents any involuntary release of the arched batten of the lower batten; in that case, the arched batten 5 is threaded onto the batten lower 2 before mounting the latter between the long sections 3.
  • the slots 53 are replaced by holes 53a crossed by the lower batten 5a, as shown in Figure 6.
  • the arched batten 5 is substantially positioned in the middle of the lower batten 2, and the apex 51 of the arched batten is thus substantially under the center of the upper batten 2.
  • a load CH is applied to the upper batten 1, for example when a person sits or lies down on the mattress supported by the box spring, the slat superior 1 deflects appreciably, and quickly the middle of the upper batten is sliding on the top 51 of the arched batten 5.
  • the slat arched 5 is deflected and the ends 52 of the batten 5 move away from each other while being guided along the lower batten 2 which plays its reinforcement role especially at the end of the deformation of the arched batten 5.
  • the damping of the battens under the weight of the load is thus progressive, and more and more resistant.
  • the constitution of the latte curved 5, material and dimensions, are determined so that the arched batten can return to its initial configuration when the load is removed, that is to say so that the deflection of the slat curved does not reach a critical value predetermined and is not irreversible.
  • the arched batten 5 is a batten wooden plywood, such as beech, which is composed of 3, 4 or 5 thin layers of beech glued together on the others and molded into a hanger.
  • the slat curved 5 at rest has an arrow F of 2.5 cm approximately and an active length C between ends support 52 of about 25 cm.
  • the thickness of the slat curved 5 is between 5 and 10 mm, like the slats 1 and 2, and has at least at the ends 52 a width less than 1.5 times the width of the lower batten 2.
  • the slots 53 can be covered with a surface layer of material anti-friction reducing the coefficient of friction between the arched batten 5 and the lower batten 2, or well formed in anti-friction material tips press fit and / or glued to ends of the arched batten.
  • the anti-friction material is a polymer, a resin epoxy, or a fluorinated plastic, such as PTFE.
  • the arched batten 5 is of thermoformed plastic, for example a olefinic polymer, such as polyethylene, polyvinyl chloride (PVC), or polystyrene, preferably transparent, or is metallic, by example in aluminum, or is in fiberglass.

  • the lower reinforcing slats are for example 4, 5 or 6 in number and are situated in a central rectangular zone Z 3 of the bed base, where the kidneys and / or the pelvis of the user normally are rest, as shown in FIG. 2.
  • each of the lower slats supports a curved slat which can be positioned by sliding on the respective lower slat independently of the other curved slats, for example substantially in the center or laterally to the left or to right depending on the comfort desired by the user.
  • the bed base has several rectangular zones Z 1 to Z 5 delimited by separately adjustable sub-frames, manually or by electric motor MO, as shown in FIG. 2, the zone where the curved slats are installed can be fixed, or mobile.
  • zones Z 1 to Z 5 of the bed base have respective curved slats, the curved slats of one of the zones possibly having stiffnesses different from the curved slats of another zone.
  • the difference in stiffness results from curved slats having different lengths of rope C, that is to say different useful lengths between support ends 52, and / or different thicknesses e, and / or different arrows F, and / or different compositions and therefore mechanical characteristics of the curved slats, such as different longitudinal elastic modules, called Young E modules.
  • the stiffness of the curved slats is greater in the central zone Z 3 where the user's kidneys rest , than in zones Z 2 and Z 4 where normally the shoulders and thighs rest respectively, these two zones Z 2 and Z 4 often being mobile.
  • the reduction in stiffness and therefore the increase in flexibility for curved slats having given compositions and sections is obtained by increasing the useful length C and / or by reducing the deflection F.
