Definitions

  • the present invention relates to a device for fastening slats to a bed base and a bed base to laths equipped with such a device.
  • Slat fasteners generally consisting of synthetic media, are designed in such a way that they extend off load in a plane horizontal and are solicited essentially at the compression in position in charge of the device.
  • Gold the anatomy of the human body consists of hollows and bumps so some areas of the body do not never use compression slats since they are not supported by these supports.
  • This latte support is consisting of a horizontal lever supported in the middle by a foot of fixation to the frame of the sommier. Each end of this lever in turn supports the middle of a lever horizontally smaller of which each termination has a fastener of known type for the end of a batten.
  • This batten support has various disadvantages of of the design of the slats support levers. Indeed, as soon as the slats are stressed, the levers tend to tilt so that it's the edges of the slats who come in direct contact with the human body, as FIG. 2 illustrates FR-A-2287194. In addition, the resistance to the vertical force of such supports is reduced, so that a break in the main lever by excessive deflection of the lever arm can not be excluded. Finally, the design of small pivoting levers does not allow a referral of an effort of the same intensity in the same opposite axis due to the decomposition of forces linked to a non-perpendicular lath support surface to the effort to which it is subjected. All these disadvantages have hindered, so far, the development of such slatted supports.
  • the object of the present invention is therefore to propose a device for fastening slats to a bed base whose design allows maintenance of a contact surface plane slats with the human body while allowing these slats to rise or to sink to fit the morphology of the human body.
  • Another object of the present invention is to propose a device for fastening slats to a bed base whose design allows to offer resistance to the effort significant vertical similar to that obtained for the traditional slat supports without levers.
  • Another object of the present invention is to propose a device for fastening slats to a bed base whose design allows a return of effort in the same axis opposite and of the same intensity so as to guarantee the comfort of the user.
  • Another object of the present invention is to propose a device for fastening slats to a bed base whose design prevents saturation from the first stresses to vertical forces, so as to to obtain a reactivity of the device authorizing movement amplitudes adapted to body morphology human.
  • the subject of the invention is a device for fastening slats to a bed base, of the type comprising a body having a fastening section to an element longitudinal section of a box spring frame and two sections of bearing for receiving slat ends extending transversely above the bed frame level, characterized in that the securing section is constituted at least two two-arm levers arranged one above each other and respectively pivoted around a pivot axis transverse to said bed frame, said levers and their pivot axes being aligned in a vertical plane at the fixed state of the device, the levers are interconnected, in the vicinity of their ends facing, by amounts of the same length articulated to said levers so as to form a deformable parallelogram, said amounts being positioned substantially in line with each section of bearing and respectively forming an element of a structure supporting a bearing section so as to ensure on at least part of the stroke of the pivoting levers when moving from an unloaded position to a position in charge of the device, a maintenance of each section of
  • the contact surfaces of the slats with the human body remain substantially flat, including in inclined levers, so that the support obtained is a support in accordance with that obtained with slat supports traditional free of levers except that this support also concerns the hollow parts of the body human.
  • the subject of the invention is also a bed base of the type slats, characterized in that it comprises at least one lath fixing device of the aforementioned type.
  • the device, object of the invention is more particularly intended for fastening laths to 2 longitudinal elements of a slat frame as shown in Figure 5.
  • the box spring frame will only be not described in more detail below because it is well known to those versed in this art.
  • the device is constituted in a manner known per se from a body having a securing section 1 to element 2 longitudinal section of the bed frame and two sections 3 of bearing for receiving slat ends extending transversely above the level of the box spring frame.
  • the fixing section 1 consists of at least two levers 4, 5 with two arms arranged one above the other and mounted respectively to pivot about an axis of pivoting 7, 8 transverse to said bed frame.
  • These pivot axes 7, 8 are generally tenoned in the longitudinal element 2 of the bed frame.
  • the levers 4, 5 and their pivot axes 7, 8 are thus aligned in a vertical plane in the fixed state of the device.
  • the levers 4, 5 are interconnected in the vicinity of their opposite ends, by amounts 9 of the same length articulated to the levers 4, 5 so as to form a deformable parallelogram. As the figures illustrate, these pivot axes 7, 8 of the levers 4, 5 are located in a median plane of the parallelogram.
  • Amounts 9 are as for them positioned substantially in line with each section 3 of tier and form respectively an element of a support structure 10 of a bearing section 3 of in order to ensure, on at least part of the race of levers 4, 5 pivoting, when moving from a position out load (Figure 1) at a load position ( Figure 2) of the device, a maintenance of each bearing section 3 in a plan substantially parallel to its off-load plan generally corresponding to a horizontal plane. From this makes, at any time, the surface of the bearing section 3 intended to receive the mattress is maintained in a plane substantially horizontal.
  • This cantilevered receiving surface 11 is supported at its free end by a bracing element 12 connecting it to the end of the upright 9 hinged to the lever 5 lower to form a triangular structure substantially indeformable. It is to highlight that the articulation 13, when it exists, between the surface 11 of landing section 3 and lever 4 superior is constituted by a thinning of matter. It is the same for the connection of the support structure 10 to the lower lever 5.
  • This articulation 13 allows the surface 11 of the support structure 10 to stay in a substantially horizontal plane when passing a position off load at a position in charge of the device because its connection with the upper lever 4.
  • a support structure 10 completely independent of the levers and contiguous only to the amounts 9 could also have been be considered without departing from the scope of the invention.
  • Each section 3 of tier is constituted of minus one, preferably two, end (s) 14 inside of which is housed each time a batten. These tips 14 are connected by a suspension structure to the support structure.
  • the basis of structure 15 of suspension comprises a notch 16 delimiting two blades susceptible to elastic deformation from the position from no load to the position in load of the device, a free pivoting of the lever 4 superior to the part of structure 15 of suspension of the bearing section 3 extending between said amounts 9 of the parallelogram.
  • this suspension structure of this bearing section 3 can affect a lot of forms.
  • this suspension structure is a hollow structure made of elastic rings deformable on crushing, said rings being positioned side by side and / or superimposed.
  • the articulations 6 of the uprights 9 to the levers 4, 5 are constituted by thinning, such as a narrowing of the cross section, to allow in each of these joints deformations by compound bending.
  • the bearing section 3, the fixing section 1 and the support structure 10 of the section 3 of bearing constitute a monolithic whole.
  • This set is preferably made for synthesis. Orifices are provided in the body of this together to lighten the weight of this set. This together is thus fixed by the pivot axes 7, 8 of the levers 4, 5 forming a tenon to the longitudinal elements 2 of the sommier frame. This results in an easy device to ascend.
  • a sommier frame will be equipped with several devices of this type, as shown in Figure 5. From such devices may be associated with devices fixing slats in which the section is fixed and the bearing section works essentially to compression.
  • the number of slats maintained in each section 3 of bearing can be any. In the examples represented, this number is equal to two.
