Definitions

  • the present invention relates to a device for fixing slats to a box spring and the box spring incorporating such a device.
  • It relates more particularly to a device for fixing slats to a box spring, of the type comprising at minus a first member fixed to a longitudinal element of the frame of the box spring, a second member forming a bearing for the receiving at least one end of a slat extending transversely above the level of the box spring frame, a spring being disposed between the first and second organs and connecting said first and second organs between them.
  • the device for fixing the slat to the bed base must be in such a way that it allows the slat to be brought in one predetermined fixed initial position with rapid return and nervous about this batten in the unloaded position without remanent deformation or hysteresis.
  • This force of recall must be capable of being increased without affecting the flexibility of the slat fixing device.
  • Such a fastening device is also required slats to be designed in such a way that it can present good resistance over time without wear of the elements component.
  • the problem of wear of the elements components of the batten fixing device is a problem that has already been addressed in the literature and attempted to be resolved.
  • An example of a slatted base in which the slat support was designed to be reduced in wear is described in document EP-A-0.150.873.
  • a slat fixing device to a box spring of the type comprising a spring substantially in V-shaped lying arranged between a slat and an element longitudinal of the box spring frame, this spring being fixed fixed way to the latter, the other end of the spring being integral with a tip for receiving the end of the latte.
  • Such a particularly rigid set had aims to limit local deformations of the spring and consequently the wear of the latter. From this device, this resulted in a very significant stiffness of all.
  • such a device required the manufacturer to use only non-extendable slats in length.
  • the batten is likely to occupy in certain spring positions a position in which it is no longer held and can then move freely in a direction transverse to the longitudinal elements of the box frame. For all the above reasons, the sliding mounting of a spring directly on a latte should be avoided.
  • the purpose of the present invention is therefore to overcome the disadvantages mentioned above by proposing a device for fixing curved slats to a box spring whose design allows a simple, comfortable set to be obtained wear limited in time.
  • Another object of the present invention is to provide a device for fixing curved slats to a bed base which meets the above requirements and is designed to so that when you vary the position of a constant force along the batten, the deflection of this latte remains almost constant.
  • Another object of the present invention is to provide a device for fixing curved slats to a box spring, the design allows the return to an initial position outside load of the slats perfectly defined by construction.
  • Another object of the invention is to propose a device for fixing curved slats to a bed base whose stroke travel and restoring force are important without however impair the flexibility of the whole.
  • the invention relates to a device for the fixing slats to a box spring, of the type comprising at minus a first member fixed to a longitudinal element of the frame of the box spring, a second member forming a bearing for the receiving at least one end of a slat extending transversely above the level of the box spring frame, a spring being disposed between the first and second organs and connecting said first and second organs between them, characterized in that each slat is a slat curved upwards and in that at least one of the ends of the spring is slidably mounted on one said first and second organs and is guided in displacement in a plane transverse to the element longitudinal of the frame of the bed base by guide means which, when switching from an unloaded position to a position in charge of the device, authorize a free sliding movement of at least one end of the spring towards the outside of the box spring frame and which, when switching from a loaded position to the unloaded position of the device, cooperate with means for limiting the spacing of the ends
  • the device has a great travel, great flexibility and great nervousness with a perfect return to position initial off load.
  • the spring consists of at least two so-called branches upper and lower, the connection area between said branches of the spring being located inside the frame of the bedspring.
  • Means for limiting the spacing of ends of the spring are in turn constituted by a stop fixed to the spring.
  • the invention also relates to a box spring type slats, characterized in that it comprises at least one device for fixing slats to a box spring such as described above.
  • the device for fixing slats 4 to a box spring object of the invention, allows the attachment of one or more slats 4 to a box spring, in particular to an element longitudinal 1 of the box spring frame.
  • FIGS. 3 and 4 correspond to a second embodiment of realization of the invention.
  • the identical bodies have been represented by numbers identical and the organs having an identical function or a similar structure were represented by numbers identical supplemented by an apostrophe.
  • the spring 3 of Figures 1 and 2 is shown in 3 'to Figures 3 and 4.
  • the device for fixing slats comprises, in known manner, a first member 9 or 9 'fixed to the longitudinal element 1 of the box spring frame and a second member 8 or 8 'forming a bearing for receiving at least one end of batten 4, this batten 4 extending transversely above the level of the box spring frame.
  • This device also comprises a spring 3 or 3 ', arranged between the first 9 or 9 'and second 8 or 8' organs and connecting said first 9 or 9 'and second 8 or 8' organs between them.
  • first and second members are partly made of classic way.
  • the first member 9 or 9 ' fixed to an element longitudinal 1 of the box spring frame, has a housing 2 or 2 ', blind or crossing, opening towards the longitudinal element 1 of the box spring frame when the fixing device is in position on said frame bedspring.
  • a trunnion, or any other fixing member 5 or 5 'suitable secures the element longitudinal 1 of the box spring frame and this first member 9 or 9 ', generally by force fitting said 5 or 5 'pin on the one hand in the 2 or 2' housing formed in the first organ, on the other hand in a bore blind 6 (not shown in Figures 3 and 4) formed in the longitudinal element 1 of the box spring frame.
  • This batten 4 is generally slidably introduced into the longitudinal direction inside said housing up to come into abutment against a shoulder arranged inside said accommodation.
  • This slat 4 is a slat curved upwards or, in other words, convex, upwardly convex to increase its flexibility stroke.
  • This slat 4 can be made of any material. The comfort of a such an arched batten cannot be matched by a non-batten curved.
  • the first and second organs include means for receiving ends of the spring 3 or 3 '.
  • at least one of ends of the spring 3 or 3 ' is slidably mounted on one of said first 9, 9 'or second 8, 8' organs and is guided in movement by guide means 11 or 11 '.
  • it is the end 3A of the spring 3 which is mounted to slide on the member 8 forming a bearing for receiving the slat 4.
  • This solution is a preferred solution.
  • it is the end 3'B of the spring 3 'which is mounted free at sliding on the first member 9 'fixed to an element longitudinal 1 of the box spring frame.
  • Guide means 11 or 11 ′ are arranged to allow sliding movement of at least one end, in the occurrence end 3A in the example shown in Figures 1 and 2 and the 3'B end in the example of Figures 3 and 4, the spring 3 or 3 'in a transverse plane to the longitudinal element 1 of the box spring frame on which the device is arranged.
  • the guide means 11 or 11 ', of the sliding end 3A, 3'B of the spring 3, 3 ' are constituted by a housing, preferably through, formed in the second member 8 for the end 3A and in the first member 9 'for the end 3', this housing extending transversely to the longitudinal element 1 of the frame and forming a guide path for the end of the spring inserted inside said housing.
  • these same guide means 11 cooperate, when switching from the loaded position (figure 2) to the unloaded position (figure 1) of the device, with means 10 for limiting the spacing of the ends 3A, Spring 3B to prevent sliding movement at least one of the ends of the spring 3 beyond a predetermined position.
  • means 10 for limiting the spacing of the ends 3A, Spring 3B to prevent sliding movement at least one of the ends of the spring 3 beyond a predetermined position.
  • it is the end 3A of the spring 3 which is sliding mounted on the second member 8 while the other end 3B is fixedly mounted on the first member 9 of the device.
  • the spring 3 or 3 ' consists of at least two branches called upper and lower, the area of connection between said branches of the spring being located at inside the box spring frame.
  • the spring 3 or 3 ' has the shape of a V lying with the bonding area arranged inside of the box spring frame.
  • the branch carrying the end 3A of the spring is sliding mounted on the device in particular on the member 8 forming a bearing while the other branch 3B of the spring is fixedly mounted on the device.
  • This branch fixed mount on the device is introduced inside a housing, preferably through, formed in the first member 9, this housing extending transversely to the longitudinal element 1 of the box spring frame.
  • This maintenance in position of the fixed end 3B of the spring is effected by positioning a clamp-type part on the end 3B of the spring, this part being applied on both sides of the spring and having on one of its branches a notch coming to be housed inside a drilling the spring, the two branches of said part being then introduced into the housing through the first organ 9.
  • a stop allows the immobilization in position of this part with respect to the second member 9.
  • the end of the spring 3 is then immobilized.
  • This branch mounted fixed on the device may include several fixing points so as to allow adjustment of the restoring force exerted by the spring 3 during deformation of the entire device. It suits in this case to provide several holes in the end 3B fixed spring. This mounting of the branch 3B of the spring allows easy disassembly of the assembly.
  • the end 3'A of the upper branch of the spring has several lights 15 which constitute several fixing points of the spring on the second member 8 'forming a batten bearing so as to allow adjustment of the restoring force exerted by the spring during the deformation of the assembly of the device.
  • This second member 8 ' has on its face lower a projecting member 16 affecting the shape of a lug coming to be housed inside a light 15 of the upper branch of the spring.
  • the spring 3 or 3 ' is, for its part, a leaf spring, of preferably progressive stiffness. It should be noted that the connection zone between the upper branch terminated by the end 3A or 3'A and the lower branch terminated by the end 3B or 3'B of the spring 3 or 3 'can affect a large number of forms. It will preferably be curved, possibly in the form of one or more open loops. Therefore, the spring can, so equivalent, assign the shape of a V, a U, an S, etc.
  • this spring 3 or 3 ' has a stiffness of value less than the stiffness of the slat 4 so that allow, initially, during the passage of the unloaded position (figure 1) at loaded position (figure 2), the deformation of the spring then the deformation of the latte. Therefore, when returning to the off position load, the batten helps the spring to return to position initial and vice versa. There is real cooperation between batten and spring during their deformations respective.
  • the first member 9 is also coated on its upper face with layer 14 of synthetic material so as to prevent the generation of harmful noise in the position in device charge.
  • the ends 3A and 3B of the spring tend to approach one from the other, the 3A end sliding inside the guide path 11 formed in the second member 8, as shown in the passage between figure 1 and figure 2, up to a maximum deformation position in which the second member 8 comes to bear on the first member 9, in particular on the synthetic surface 14 covering this first organ 9.
  • the end 3A of the spring tends to move slidingly in the opposite direction, i.e. in the direction of the arrow B in figure 1, to return to its position initial.
  • the device includes means 10 or 10 'for limiting the spacing of the ends 3A, 3B or 3'A, 3'B of the spring 3 or 3 'to prevent sliding movement of at least minus one of the ends of the spring 3 or 3 'beyond a predetermined position.
  • These 10 or 10 'means of limitation the distance between the ends of the spring may affect a lot of shapes.
  • these means 10 for limiting the spacing ends of the spring 3 somehow constitute an end stop of the spring 3 during its passage from the loaded position to the unloaded position. In this example, these means consist of a stop secured to the spring 3.
  • This stop 10 secured to the spring 3, is formed on an added piece 12 forming slide.
  • This slide is secured to spring 3 at by means of a lug 7 which is housed inside a drilling made at its free end 3A of the spring.
  • This slide comprises a stop 10 constituted by a shoulder provided at its end. This facilitates mounting and disassembly of the spring and optionally allows change this spring easily. So when passing from the loaded position ( Figure 2) to the off position load ( Figure 1) of the device, this stop 10 comes in support against a face of the second member 8 and prevents displacement of the free end 3A of the spring beyond this predetermined position.
  • these means 10 for limiting the spacing of the ends 3A, 3B of the spring can be considered.
  • the means 10 'for limiting the distance between the ends 3'A, 3'B of the spring 3 ' are constituted by a hollow structure inserted between first 9 'and second 8' organs and forming in cooperation with said first 9 'and second member 8' an elastically deformable ring.
  • This structure is arranged in a plane parallel to the passing vertical plane by the longitudinal element 1 of the box spring frame on which the device is fixed. Therefore, when passing a unloaded position to a loaded position of device, the free end 3'B of the spring tends to slide in its guide path 11 ', the structure annular hollow tends to deform by flattening and the batten 4 lengthens.
  • this spring works in an adequate position and does not tend to pull the batten.
  • the end free to slide 3'B slides in reverse direction thanks to the guide means 11 ', the slat 4 returns to its initial position and the spring is prevented from deforming by spacing its ends 3'A and 3'B thanks to the means 10 'for limiting this spacing.
  • the ring structure returns to its original position after deformation, position corresponding to Figures 3 and 4 in which the spacing between the ends 3'A and 3'B of the spring is perfectly defined. This results in a position initial of the device perfectly safe.
  • the second member 8 which takes the form of a nozzle the interior of which is fixedly housed said slat 4, further comprises at its base a notch 13 providing on both sides two blades susceptible to deformation elastic to allow, when passing from the position unloaded at the loaded position of the device, a pivoting of the end piece 8 cooperating in a setting the horizontal of the slat 4.
  • the slatted type bed base comprising at least one device for fixing slats to a box spring of the type above is thus made particularly efficient.
