Definitions
- the present invention relates to a device for fixing slats to a box spring as well as a box spring slats fitted with such a device.
- Slat fixing devices usually consist of synthetic materials, are designed in such a way that they extend off load in a plane horizontal and are used primarily at the compression in load position of the device.
- Gold the anatomy of the human body is made up of hollows and bumps so that certain areas of the body don't never put pressure on the slat supports since they are not supported by these supports.
- This batten support is consisting of a horizontal lever supported in the middle by a foot for fixing to the box spring frame. Each end of this lever in turn supports the middle of a lever smaller horizontal with each termination having a fastener of known type for the end of a slat.
- This batten support has various drawbacks due to the fact of the design of the slat support levers. Indeed, as soon as the slats are used, the levers tend to tilt so that these are the edges of the slats that come into direct contact with the human body, like illustrated in FIG. 2 of patent FR-A-2287194. In addition, the resistance to vertical stress of such supports is reduced, so that a breakage of the main lever by excessive flexing of the lever arm cannot be excluded. Finally, the design of the small pivoting levers does not allow a return of an effort of the same intensity in the same opposite axis due to the decomposition of forces linked to a non-perpendicular slat support surface to the effort to which it is subject. All these drawbacks have hindered, to date, the development of such slat supports.
- the aim of the present invention is therefore to propose a device for fixing slats to a box spring, the design allows maintenance of a contact surface plane slats with the human body while allowing these slats to rise or sink to adapt to the morphology of the human body.
- Another object of the present invention is to provide a device for fixing slats to a box spring, the design provides resistance to stress significant vertical similar to that obtained for traditional slat supports without levers.
- Another object of the present invention is to provide a device for fixing slats to a box spring, the design allows a return of the effort in the same axis opposite and of the same intensity so as to guarantee the user comfort.
- Another object of the present invention is to provide a device for fixing slats to a box spring, the design prevents saturation from the very first stresses on vertical forces, so that obtain a reactivity of the device authorizing range of motion adapted to body morphology human.
- the invention relates to a device for the fixing slats to a box spring, of the type comprising a body having a section for fixing to an element longitudinal of a box spring frame and two sections of landing for receiving ends of slats extending transversely above the level of the box spring frame, characterized in that the fixing section consists at least two levers with two arms arranged one above on the other and respectively pivotally mounted around a pivot axis transverse to said box spring frame, said levers and their pivot axes being aligned in a vertical plane in the fixed state of the device, the levers being connected together, in the vicinity of their opposite ends, by uprights of the same length articulated to said levers so as to form a deformable parallelogram, said uprights 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 switching from an unloaded position to a position in charge of the device, maintaining each section
- the slat contact surfaces with the human body remain substantially flat, including in position inclined levers, so that the support obtained is a support conforming to that obtained with slat supports traditional levers free except that this support also concerns the hollow parts of the body human.
- the invention also relates to a box spring type slats, characterized in that it comprises at least one slat fixing device of the aforementioned type.
- the device which is the subject of the invention is more particularly intended for fixing slats to 2 longitudinal elements of a slatted frame frame as illustrated in figure 5.
- the box spring frame will only not described in more detail below as it is well known in those versed in this art.
- the device consists in a manner known per se of a body having a section 1 for fixing to the element 2 longitudinal of the box spring frame and two sections 3 of landing for receiving ends of slats extending transversely above the level of the box spring frame.
- Attachment section 1 consists of at least two levers 4, 5 with two arms arranged one above the other and pivotally mounted around an axis of pivoting 7, 8 transverse to said box spring frame. These pivot axes 7, 8 are generally tenoned in the longitudinal element 2 of the box spring 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 connected together, in the vicinity of their opposite ends, by uprights 9 of the same length articulated to 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.
- the amounts 9 are as for them, positioned substantially in line with each bearing section 3 and respectively form an element a support structure 10 for a section 3 bearing so as to ensure, on at least part of the travel of levers 4, 5 pivoting, when passing from an out position load (Figure 1) at a loaded position ( Figure 2) of the device, maintaining each section 3 of bearing in a plane substantially parallel to its plan without load generally corresponding to a horizontal plane. From this makes the surface of the bearing section 3 at any time intended to receive the mattress is held in a plane substantially horizontal.
- the support structures 10 for the bearing sections 3, arranged outside the parallelogram, on both sides other amounts 9, are respectively constituted a surface 11 for receiving the bearing section 3 arranged in the extension of the upper lever 4 and preferably connected in an articulated manner to the latter.
- 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 articulated to the lever 5 lower to form a triangular structure substantially undeformable.
- the articulation 13, when it exists, between the surface 11 receiving section 3 bearing and lever 4 upper consists of a thinning of material. The same applies to 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 from a position unloaded at a loaded position of the device due to of its connection with the upper lever 4.
- a support structure 10 completely independent of the levers and attached only to amounts 9 could also have been be considered without departing from the scope of the invention.
- Each bearing section 3 is made up of at least minus one, preferably two, tip (s) 14 inside which is housed each time a slat. These tips 14 are connected by a suspension structure 15 to the support structure 10.
- the basis of structure 15 of suspension has a notch 16 delimiting two blades susceptible to elastic deformation to allow, when the transition from the no-load position to the position in load of the device, free pivoting of the lever 4 higher than the part of the structure 15 of suspension of bearing section 3 extending between said uprights 9 of the parallelogram.
- the suspension structure 15 of this bearing section 3 can affect a large number of forms.
- this suspension structure 15 is a hollow structure made of elastic rings deformable to crushing, said rings being positioned side by side and / or in a stacked state.
- the joints 6 of the uprights 9 to the levers 4, 5 are consisting of 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 bearing section 3 constitute a monolithic assembly.
- This set is preferably made in terms of synthesis. Holes are provided in the body of this together to lighten the weight of this set.
- This assembly is thus fixed by the pivot axes 7, 8 of levers 4, 5 forming a tenon to the longitudinal elements 2 of the box spring frame. This results in an easy device to ascend.
- a box spring frame will be equipped with several devices of this type, as shown in Figure 5. From such devices may be associated with devices for fixing conventional slats in which the cross-section fixing is fixed and the bearing section works essentially compression.
- the number of slats maintained in each bearing section 3 can be arbitrary. In the examples represented, this number is equal to two.
