Abstract

ABSTRACT OF THE DISCLOSURE
The mattress for a bed consists of flexibly supported slats that are spaced apart and are parallel to each other. The slats are arranged at the face ends in supporting elements that can move in side elements of the bed. Each supporting element lies on its underside on a plurality of bands that are arranged above each other to ensure a progressive springing action when the supporting elements are moved in the vertical direction. This arrangement imparts outstanding sprung comfort to the mattress and excellent adaptation to various body profiles. Even the heaviest body weights do not move the supporting elements against the stops, which would disable the spring action. Because of the progressive spring action that is ensured, there is still a spring action even if the whole body weight is applied to the supporting element at a single point.

Description

- 1331~

The present invention relates to a mattress for a bed or the like, having at least one band arranged in a side element and passing over rollers on which rest supporting elements movable in vertical ~uides. Each supporting element is attached, preferably through a shaft, to the side of a slat, the slats being parallel and spaced apart ~rom each other and forming the mattress of the bed.

Such a mattress is known, for example, from CH 663 339 or PCT
WO 88/0~905.

Both of these known mattresss have the disadvantages that a relatively unsatisfactory degree of comfort is provided by the springing thereof, and that there is inadequate matching of the mattress to various body shapes at various body weights. -It has been shown when only a single band is employed, as disclosed in the above references, one either has to adjust ;;
the band to the point where it is 50 hard that even in the case of the heaviest, punctiform application of body weight the supporting element does not come to rest on the lower stop, or else a softer spring for the band must be used.
Then, of course, one obtains greater comfort from the springing, although this entails the disadvantage that when the total body weight is applied at one point, this supporting element comes to rest on a lower stop in the side -element of the bed and the spring action is disabled.
' It is an object of the present invention to develop a mattress of the type described for which adequate springing is provided even when weight is applied to the supporting element at one point, and without any restriction on the spring action due. to impact on the lower support.

According to the present invention there is provided a ;
mattress for a bed or the like, comprising a pluxality of ~UL_ B - :-133~

slats that are parallel and spaced apart from ~ach other to form a reclining surface of the bed, a plurality of bands B ~K~arranged in a side element of the mattress and passing over rollers on which rest supporting elements that can move in vertical guides, said bands being spaced apart vertically, each of said supporting elements being attached to one side of a slat, and said supporting elements being arranged such that pressure thereon causes them to move progressively into contact with said vertically spaced~ bands.

An important feature of the present invention is that not only is one band associated with the supporting elements, but also that the supporting elements can be rested sequentially upon a plurality of bands that are separated vertically one above the other by a distance that is a function of the load applied to them.

There is a progressive springing characteristic associated with each supporting element. When subjected to a slight load, the supporting element will lie on the upper band section of the upper band. As the load increases, the upper `;
band will stretch, which causes the supporting element to be ~
moved vertically downwards in to the guide grooves of the ~`
side element, and the supporting element will not only come `~
into contact with the upper section of the band but also with an additional upper band section of a second band.

At this point, the restoring force on the supporting element is already considerable. If an even greater load is applied ! ` ' to the supporting element, the two upper sections of the band are moved further downwards during elastic extension and the supporting element them comes to rest on the lower band I section of the middle band: on additional loading of the i supporting element, all three sections of band are moved and j fir.ally comes to rest on the fourth band section, which is the lower section of the first band. Thus, depending on the load on the supporting element, each supporting element incorporates a progressive springing characteristic in a vertical direction.

Thus, impingement of the supporting element, even during the highest, point loading of this siupporting element, is avoided, even if this supporting element is subjected to the full body weight of the user. Impact on the lower stop is prevented for all practical purposes. This means that even when subjected to the heavi2st body weight, the supporting element will still provide good springing performance.
,' ,. ,' Such a mattress can be used for all body weights, and even the heaviest bodies will be adequately sprung without any -~
impact of the supporting elements on the stops located at the bottom of the sides of the side elements.
': :
In a preferred embodiment oP the present invention, two endless bands are used, the sections of the band being spaced apart vertically. In addition to using two bands, more than two bands can also be used.

There are various possibilities for selecting the material used for the bands. One can use a band material such as a woven or knitted rubber band that can stretch longitudinally.
In the same way, however, one can use bands that do not stretch as readily in the longitudinal directionl such as woven textile bands, plastic bands with sufficient longitudinal stretch, or others. `

It is also important that the supporting elements are so guided within grooves incorporated in the side elements that ~;~
there can be absolutely no binding in these grooves during vertical movement in the area of these grooves.

It is also preferred that the length of the closed bands does not extend over the whole length of the mattress, but that the mattress is divided up. Such a division can be effected, :` 3 c~

in the manner known per se, from the head area to the shoulder area, from the shoulder area to the lumbar area, and from the lumbar area to the feet.

The closed bands can be associated with each of these areas so that, for example, if the mattress is divided into three areas, each such area will have an associated band arrangement of the type described heretofore.

Appropriate selection of the longitudinal elasticity of the bands that are used can ensure that each area has different springing characteristics.

In a further feature of the invention optimal matching of the mattress to various body shapes at various body weights is ensured. In the upper section of each supporting element there is a recess in which a ball head fits. The ball head, which is supported therein so as to be movable, rotatable, -;
and pivotable, i9 joined to a shaft that is in turn joined to the face side of a slat so as to be rotatable. In this way, the slats are supported flexibly in the supporting elements through the ball heads arranged on the face side. ~`
' ' when a slat flexes, this leads to a reduction of its axial ~;-length. Such a shortening of the axial length when the slat flexes is evened out in that the ball head is arranged in the recess within the supporting element so as to be able to move. In this manner, the slats are not under axial tension, but can spring freely.

Using a ball head in the appropriately shaped recess means that the slats are supported in each of the face-side recess in such a way that it can pivot, so that here, too, the slats can flex freely. Furthermore, the slats are supported so as to be able to rotate, so that optimal matching to the body shape of the user is ensured.

Figure 10 is a side view of a slat as in figure 9;
Figure 11 is a view, at enlarged scale, of a supporting ~:
element as in figure 8; ~-~
Figure 12 is an end view of the slat shown in Figures 9 and :~
10. -A slat framework 1 (see figure 4) is essentially formed from slats 17 that are supported flexibly so as to be movable with each of their face ends in a supporting element 22. The --supporting elements 22 are movable in a vertical direction and are supported in a side element 2, 3 so as to be sprung .~;
against the force of bands 7, 7a.
, Each side element consists of two halves, an outer side element 2 and an inner side element 3 being defined in each ~:
instance. The inner side element 3 is oriented towards the ~:
mattress, whereas the outer side element 2 is joined to a bed . ~:
side that is not shown in greater detail herein.
J, . ~ , ', ~ ' ~'~

l~3l~a3 Between the two side elements 2, 3 there is a recess 4 (see figure 7), in which the guide for the supportiny elements 22 and the guide for the bands with the rollers 5, 6, and the bands 7, 7a themselves are arranged. ~ach supporting element 22 is guided in a vertical groove 11 in the side elements 2, 3 so as to be movable.

The line of separation 40 between the side elements 2, 3 is shown by way of example in figure 6.

As can be seen in figure 8, each of the side elements is a wooden body of approximate rectangular or square cross-section, there being a recess 12 for a ball head 15 on the slat 17 in the upper section, whereas the lower section of the supporting element is configured as a rounded supporting surface 8, with which the supporting element 22 can be rested on the different bands 7, 7a that are arranged so as to be spaced apart one above the other, 29 to 32.
~: :
It can be seen from figure 1 that the supporting surface 8 of the supporting element 22 initially rests on the upper band section 37 of the upper band 7. ;~

On further vertical movement of the particular supporting element, the supporting surface 8 moves downward with the upper section 37 and the supporting surface 8 then comes into ~; contact with the upper section 37a of a second band 7a that is arranged thereunder. ;~

On further vertical movement the gap 30 is closed and the two sections 37, 37a of the band come into contact with the lower section 38a of the middle band 7a. ;;~

Insofar as the supporting element continues to move further downward in a vertical direction during the development of ever stronger resistive force, the sections 37, 37a, 38a finally come to rest on the section 38 of the upper band 7 by ;~

':"',~

1 3 3 1 4 ~ ~

closing the gap 31. Thus, all of the sections 37, 37a or 38, 38a touch each other.

This means that a powerful restoring force is exerted upwards on the supporting element 22, with the result that the supporting element 22 can withstancl the heaviest body weight that is applied at a point and will retains its spring action because of the progressive springing action described heretofore.

The continued path of the spring movement is defined by the space 32 between the lower band section 38 of the band 7 and a lower stop surface 41 in the side element 2.

Each band 7, 7a is in the form of an endless closed loop.
The upper band 7 passes around guide rollers 5, the guide rollers being distributed evenly along the axial length of the side elements 2, 3.

The firmness of the spring action of the bands 7, 7a can be adjusted by selection of the number of rollers 5 and 6 that are used.

In the embodiment shown, in each instance two supporting elements 22 lie on the ree band sections 37, 38 or 37a, 38a, respectively, of the bands 7, 7a. It is also possible to arrange a roller 5, 6 of this sort between every supporting element 22 in order to make the spring action firmer.

Comparison of figures 1, 2 and 5 shows that the rollers 5, 6 are supported so as to be able to rotate with suitable stub shafts in associated drilled holes 26 in the side elements 2, 3.

The side elements 2, 3 are connected by trunnions 24 that are arranged in the inner side of the side element 2 and fit into !

x; `

~ 3 3 ~

associated drilled holes 25 in the inner side of the other side element 3.

A pin 27 is arranged in the lower part of each supporting element (see figure 8) as a retainer. This pin 27 fits through the slot 9 within the inner side element 3, and as shown in figure 7 can come to rest on the lower edge of the stop 2~ when the supporting element is in the uppermost position. This prevents the supporting elem~nt 22 from being withdrawn from its groove 11 in the side element 2, 3.

The width 39 of the groove 11 is made greater than the width 36 of the slot 9 so as to avoid the supporting element falling forward out of the groove 11. This results in excellent, tilt-free guidance for the supporting elements 22.

It can be seen from figure 6 in conjunction with figures 9 to 12 that each slat 17 is supported so as to be movable in the direction indicated by the arrow 18 (in the direction of its axial extent) through a ball head 15 in the recess 12 of the supporting element 22.

This ball head 15 permits a flexible adjustment of the slat 17 in the direction indicated by the arrow 19 and in the direction indicated by the arrow 20.

This means that each slat 17 can adapt individually to the body weight that is applied to it, as shown in figure 4~ A
limiting stop is provided for the event of extreme flexing. -~
~",,,, In this connection, the lower side of the slat 17 comes into contact with a rail 23 that is arranged on the inner side of the inner side element 3. The rail 23 is provided with a cushion 16 that :is of felt, for example. In the same way, a cushion 42 is incorporated in the top surface of the side elements 2, 3. -.~ . ...
`'"'. ' - 8 - ~
. . .

~331~

The ball head 15 is connected to the slat 17 through a shaft 14, the shaft 14 being held in the drilled hole 21 in the slat 17 so as to be able to rotate.

In order to provide lateral guidance of the bands, the supporting surface 8 is configured as a U-shaped profile on the under side of the supporting elements 22 and forms a U-shaped recess 35 thereby. The base arm is thereby formed by the rounded supporting surface 8, whereas the side arms are formed by the side extensions 33, 34 of the supporting element 22.

Because of the rounding of the supporting surface 8, the band is bent gently and the shape of the supporting element 8 follows the flexing of the band, thereby ensuring a longer service life of the bands.
