Abstract

The support has a spring strip with ends held in a retaining unit and a contact surface formed within a support element (3). Side parts (5, 6) of the support element are provided with a bridging element (15). End regions (16) of the bridging element are turned away from the side parts of the support element and aligned against each other. The end regions are connected with each other by a hinged connection (17), so that a damping element (21) is attached to both the side parts of the support element to dampen longitudinal carriers when loading the mattress support in a resilient manner.

Description

The present invention relates to a lower mattress for a bed, comprising two extending in the longitudinal direction of the bed, spaced apart longitudinal beams, a plurality of these longitudinal beams in supporting support elements, which support elements are movable about these supports in a plane perpendicular to the longitudinal members level, which Support members extend above the side members and are oriented transversely thereto and the two side parts are projecting beyond the side members, holding means which are attached to the outer end portions of the side parts of the support members, and spring strips whose ends are held in the holding means, and above Support elements form a support surface for a mattress top.

Such sub-mattresses are known and serve as a support for a mattress top. Characteristic of such sub-mattresses is that they do without frames and thus give the viewer of such a bed the impression of a very lightweight design. In one-sided load of such a bed but also gives the impression that due to different deflections on both sides of the bed gives a tilt, so that, for example, the person who is on the edge of such a bed or sitting on it gets the impression that by this lateral inclination he feels exposed to the risk of sliding off the edge of the bed.

From the EP-A-0 710 459 Such a sub-mattress is known, which is constructed so that the lateral inclination is counteracted in one-sided loading. In this case, a lateral compression of a support bar is transmitted via a spring bar on the opposite region of this support strip, thereby the effect is achieved that springs in one-sided compression of a support strip and the opposite side of this support strip, if only to a lesser extent.

The object of the present invention is thus to improve the structure of a lower mattress such that the deflection of a Supporting element is transferred at lateral load of a bed substantially equally to the opposite side region of this support element, so that any tendency of a mattress can be avoided in lateral load.

According to the invention, the solution of this object is achieved in that both side parts of a support element are provided with a bridge element, the side parts facing away from the end portions are directed against each other and are connected to each other via an articulated connection, that on both sides damping elements are mounted, which the pivoting of the side parts dampen the respective longitudinal beam under load of the lower mattress spring.

With this invention it is achieved that when lateral load of the lower mattress for a bed of a side part is pivoted about the support in the longitudinal member in a plane perpendicular to the longitudinal members level, this pivoting movement is also carried out by the pivoted on this side part mounted bridge element on the articulated connection will transmit this pivoting to the bridge member which is mounted on the opposite side part, whereby it is achieved that the opposite side part is pivoted by approximately the same amount as the side part pivoted by the one-sided load. This pivoting of the two side parts with the bridge elements attached thereto, which are connected to each other via an articulated connection, is cushioned by damping elements. This cushioning is achieved by both pivoted side parts with the damping elements provided thereon. This results in an optimal way under load over the entire width of the bed spreading deflection, regardless of the lateral position in which the load occurs. This also optimal sleep comfort for the person using such a bed is achieved.

In an advantageous manner, the two side parts of a support element each have a projection, which in each case has a surface running along the outside of the corresponding longitudinal support, and is the respective damping element between this surface and the outside of the longitudinal member used. In addition to the simple structure of this embodiment, there is also an optimum suspension or damping of the corresponding support element.

Advantageously, the damping element is formed from an elastic body, which is displaceable between the surface of the projection and the outside of the respective longitudinal member substantially in the plane perpendicular to the longitudinal members to and from the corresponding support. Thereby, the spring characteristic of each support element can be adapted to the desired needs.

A further advantageous embodiment of the invention is that in the region of the articulated connection of two opposing bridge elements damping means are mounted. In addition to the supporting effect of this damping means to the damping elements is additionally achieved that the bridge elements and consequently the side parts move back to the starting position in the unloaded state.

Advantageously, the articulated connection between the bridge elements is designed as a pivot bearing, which allows a very simple and inexpensive construction.

A further advantageous embodiment of the invention consists in that the damping means are formed from an elastic body, that in each case a plate is attached to the side portions facing away from the end portions of the bridge elements, and that an elastic body is inserted between each two plates of two interconnected bridge elements. This also results in a particularly simple and effective structure of this damping means.

An embodiment of the present application will be explained in more detail by way of example with reference to the accompanying drawings.

Out Fig. 1 Parts of two longitudinal beams 1 and 2 are shown, which extend as known over the entire length of a bed in the longitudinal direction. On these side rails 1 and 2 support elements 3 are placed, of which in Fig. 1 only one is shown. In a bed several such support elements 3 are placed over the entire length of the side members 1 and 2. These support elements are connected in supports 4 with these side rails 1 and 2. These supports 4 are designed in a known manner so that the support elements 3 rest on these supports 4 such that they are pivotable about these supports 4, in a plane which is aligned perpendicular to the longitudinal members 1 and 2, which means that these support elements 3 in this plane around the supports 4 can perform a weighing movement or a pivoting movement. At the same time, the supports 4 are designed such that the support elements 3 are held in such a way that tilting out of said plane becomes impossible, but that a displacement transversely to the longitudinal supports 1 and 2 is made possible.

Each support element 3 comprises two side parts 5 and 6, which are each above the two side members 1 and 2 above. At the outer edge regions 7 of these side parts 5 and 6 holding means 8 are mounted, which are formed with two pockets 9 and 10, respectively. In the respective pockets 9 and 10, the ends 11 of spring strips 12 are inserted. This spring strips form a support surface 13, on which a mattress, not shown, can be placed. In the exemplary embodiment shown here, the holding means 8 each have two pockets 9 and 10, so that two spring strips 12 can be held by a support element 3. Of course, retaining means could also be used which, for example, have one or three pockets, so that one or three spring strips could be used per support element. Here, the holding means 8 are made in a known manner from an elastomer and designed so that these holding means 8 allow an inclination of the spring strips 12 with respect to the side members 1 and 2, so that the support surface 13 can adjust under load according to the deformation of the top mattress.

Like also out Fig. 1 it can be seen, the two side members 1 and 2 are interconnected by cross braces 14. In a known and not shown, feet 1 and 2 can be attached to these two side rails, on which then the lower mattress comes to rest.

Like also out Fig. 1 it can be seen, the two side parts 5 and 6 are each provided with a bridge element 15, the side portions 5 and 6 facing away from end portions 16 are directed against each other and via an articulated connection 17, which will be described later in detail, connected to each other.

Like also out Fig. 1 it can be seen, the two side parts 5 and 6 are each provided with a projection 18, each having a along the outer side 19 of the corresponding longitudinal member 1, 2 extending surface 20. Between this surface 20 and the outer surface 19, a damping element 21 is used in each case, which will be described in detail later.

Fig. 2 shows the view of a support member 3 which is supported on the supports 4 on the longitudinal beams 1 and 2 and on the retaining means 8 carries the spring bar 12, in the unloaded state. By the damping elements 21 it is achieved that the side parts 5 and 6 are in the raised state, while the two bridge elements 15, which are connected to each other via the articulated connection 17, are in the lowered position.

The Fig. 3 shows in an enlarged view a damping element 21. This damping element 21 is inserted into a slot-shaped recess 22 which is mounted in the surface 20 of the projection 18 of the support element 3. The slot-shaped recess 22 is also made Fig. 4 seen. This damping element 21, which may be formed of an elastic body, is displaceable along the slot-shaped recess 22, wherein, as shown in FIG Fig. 4 can be seen, a screening 23 may be provided, which is shown here schematically, with which the damping element 21 can be kept in the set position in a known manner. In the embodiment shown here, the damping element 21 is wedge-shaped and is supported on a correspondingly shaped wedge 24, which is attached to the outer surface 19 of the respective longitudinal member 1, 2. By moving the damping element 21 thus the hardness of the deflection can be adjusted, the pivoting of the side part 5, 6 to the support 4 thus encounters greater or lesser resilient resistance through the damping element, the hardness of the deflection can thus be adjusted.

Fig. 5 shows in an enlarged spatial representation of the articulated connection 17 of the two bridge elements 15. The end portions 16 of the two bridge elements 16 are provided with tabs 25 which are provided in a known manner with a bore into which a hinge pin 26 inserted is, whereby a pivot bearing is formed. At the two end portions 16 of the two bridge elements 15, a plate 27 is mounted in each case, which in the unloaded state of the support element 3, as this in Fig. 2 and also in Fig. 5 is shown, against the hinge pin 26 towards each other inclined. Between these plates, an elastic body 28 is inserted. This elastic body 28, in support of the damping elements 21 (FIG. FIGS. 2 and 3 ), that in the unloaded state of the support element 3, the two side parts 5 and 6 raise, while the bridge elements 15 are lowered. However, depending on the hardness of this elastic body 28, it also influences the compression hardness of the support element 3 when it is loaded.

In the loaded state of the support element 3, as in Fig. 6 is shown, the two side parts 5 and 6 of the support element 3 pivot about the supports 4 on both sides of the side members 1 and 2 against the bottom. The two bridge elements 15, which are connected to each other via the articulated connection 17, are pivoted about the supports 4 upwards. This pivoting movement of the two side parts 5 and 6 and the bridge elements 15 are cushioned by the damping elements 21 and the elastic body 28, wherein the compression hardness, as already described, can be adjusted by the adjustment of the damping elements 21. Figure 7 shows in an enlarged view the compression of the damping element 21 in Fig. 6 illustrated loaded state of the support element. 3

How out Fig. 6 it can be seen, a pivoting of the two side parts 5 and 6 to the support 4 due to the articulated connection 17 of the two bridge elements 15 practically always in a substantially symmetrical manner, regardless of whether the load on the support member 3 via the spring strips 12 in the middle or sideways. For example, if the load represented by the arrow 29 in FIG Fig. 6 On the left side on the spring strips 12 and the support member 3, the side member 5 is pivoted about the support 4 counterclockwise, the bridge element 15, which is formed on the side part 5, is also pivoted about the support 4 of the longitudinal member 1 in the counterclockwise direction , About the articulated connection 17 takes the bridge element 15 of the side part 5 and the bridge element 15 of the side part 6 with, this is the support 4 of the longitudinal member 2 pivoted clockwise, and takes the side part 6 with, that is, the side part 6 is also pivoted about the support of the longitudinal member 2 in a clockwise direction. This ensures that even at lateral load both side parts 5 and 6 lower, thus held by this support element 3 spring strips 12 thus remain in the loaded state, even if this load is carried laterally, practically aligned horizontally. An inclination of the support surface 13 to the side is thus avoided even with lateral load of the bed.
