FR2763491A1 - ANTI-TIPPING DEVICE FOR SUPPORT OF OVERFLOW MATTRESS - Google Patents

Abstract

The anti-tip device consists of horizontal connecting rods (10) held against the tilting surface (3) of the mattress support by bearings (11). The rods connect two opposite lateral supports (7) and form between them a return linkage. A connecting rod (12) with a guide finger (13) at the ends of each rod, enters a groove (14) of said lateral support (7). Application to deformable bed bases.

Description

The invention relates to bed bases and more generally to any support

  mattresses whose lateral parts are cantilevered relative to the frame on which it rests, and it relates more precisely to an anti-tip device of the element or elements constituting the support. The invention is particularly applicable to bed bases with flexible supports and in particular to slatted bed bases, which are articulated so that at least the head and the foot can be raised in several positions. The tilting parts are obviously not fixed to the support frame and rest on pivoting rods or levers. In the case of a deformable bed base with an ergonomic profile as described in Patent Application No. 95 13463 in the name of the Applicant, flexible strips to which the slats are linked, rest on lifting members. In all cases, the articulation and lifting mechanisms are arranged under the sleeping surface and attached to the frame which serves as a support for said tilting parts on which the slats are fixed or rest. To limit the footprint of said frame and so that these mechanisms are not visible from the outside, there is a tendency to reduce the width of the frame relative to that of the sleeping surface. As a result, the lateral parts of the bed base, in this case the end of the flexible support or of the support slats, are cantilevered above the frame. The slats rigidly fixed to the support can absorb the weight of a person sitting on the edge of the mattress. But in an articulated bed base and in particular the bed base with an ergonomic profile, certain slats are only supported on their support and it is understood that if pressure is exerted on one of their ends at this point they will be able to tilt, not being retained at

their opposite ends.

  The invention aims to overcome this drawback in a simple and effective way by proposing an anti-tip device adapted to the tilting parts of the articulated bases. The subject of the invention is therefore an anti-tip device for a cantilever mattress support of which at least certain tilting lateral parts rest directly on a rigid base, lifting mechanisms which can act on said tilting lateral parts by means of articulated lateral supports, device according to which at least one horizontal connecting rod is held against the tilting surface of the mattress support, rod which connects two opposite lateral supports to form a return linkage between them, the connecting rod

  articulated on the supports by a sliding system.

  More specifically, the connecting rod ends at each end with a connecting rod and a penetrating guide finger

in a groove in the support.

  Other characteristics and advantages of the invention

  will emerge from the description which follows, from an example

  of embodiment, with reference to the accompanying drawings which represent: Figure 1, a cutaway perspective view of a mattress support with its anti-tip device, Figure 2, a schematic sectional view of a box spring frame. Figure 3, a schematic sectional view of the box spring frame equipped with the anti-tip device according

the invention.

  Figure 4, a partial front view of a part

  side of the bed base in the rest position.

  Figure 5, a plan view of the box spring part

according to figure 4.

  Figure 6, a view of the box spring part of the

Figure 4 in the raised position.

  There is shown in Figures 1 to 6 a deformable box spring said ergonomic profile which we see a part

  liftable bust using articulated parts.

  The frame of the bed base 1 consists of a rigid base 6 with two plates mounted on a base 2, and the bed base itself comprises at its base two flexible lateral bands or else a flexible surface 3 resting directly on the base 6 as is seen more precisely in Figures 2 and 3. The flexible surface receives rows of springs 4, the assembly being capped with upholstery or a covering fabric 5. It is noted that the bed base 1 thus produced extends beyond and on the other side of base 6, part of the

  box spring being cantilevered (Figure 3).

  With reference also to FIGS. 3 and 6, it can be seen that a support 7 with a rounded and ergonomic profile is located under the surface 3 of the bed base, along each plate of the base 6. One end of each support 7 is fixed to the same pivoting crossbar 8. The other end 9 of the support can come to bear on the headrest of the bed base as

  shown in more detail in Figure 6.

  The profiled support 7 can pivot from the horizontal position of the box spring seen in FIG. 4, to the raised position of FIG. 6 under the action of motorized lifting mechanisms not shown which act on said profiled support 7 constituting the tilting lateral part of the box spring . It is understood that thus, during its lifting movement, the flexible surface 3 of the bed base will marry the

  rounded contour of the ergonomic support 7.

  Figure 2 shows the assembly described above, not equipped with the tilting device according to the invention. The flexible surface 3 being only in support, in a horizontal position, on the base 6, it is understood that if there is pressure on one side of the bed base 1, as illustrated by the arrow, for example if a person sits on the edge of

bed, the box spring will tip over.

  The proposed anti-tip device, visible in Figure 1 and Figures 3 and following, includes two horizontal connecting rods 10 held under the flexible surface

  and tilting 3 of the bed base by fixing bearings 11.

  Each end of the rod carries a connecting rod 12 which extends

  in a vertical plane, parallel to the base plates 6.

  Each connecting rod 12 itself ends with a guide finger 13 which enters a groove 14 provided in the ergonomic support 7. In the position of FIG. 4, it is noted that the fingers 13 are at the end of their corresponding groove . During lifting (Figure 6), the support 7 will gradually apply against the flexible surface 3. As the connecting rod 10 pivots in its bearings 11 and the fingers 13 slide in the grooves 14. Whatever the position of the chest part of the bed base 1 the fingers 13 allow the flexible surface 3 to be hooked to the supports 7. The connecting rod 10 is thus articulated on the supports by a sliding system and constitutes a connecting rod assembly between the two lateral parts of the bed base. Thus any tilting, caused by a cantilevered support on one side, will be blocked by the fingers 13 on the opposite side, taken in the grooves 14 of the

corresponding support.

  The bust part is shown with two connecting rods. In some cases, one might be enough. We can

also plan more.

  Other lifting parts of the bed base, for example the foot part, could be fitted with a device

equivalent anti-tip.

  The invention also applies to slatted bed bases whose end pieces are fixed from place to place on strips

  flexible side rests, as in the description

  previous, on ergonomic supports.
