Base mattress for a bed
The present invention relates to a mattress base for a bed. Comprising two longitudinal supports which extend in the longitudinal direction of the bed and are spaced apart from one another, a multiplicity of support elements, which are held on these longitudinal supports in bearings and which support elements, are arranged transversely to these longitudinal supports and may be moved around these bearings in a plane perpendicular to the longitudinal supports, and which are each provided with a bridge element whose end regions remote from the side parts are directed towards one another and are movably connected to one another, wherein holding means are attached to the outer end regions of the side parts of the support elements, while spring slats whose ends are held in the holding means form a support surface for a mattress above the support elements.
Such mattress bases are known, e.g. from EP 1 989 973 A. In this case, the support elements are designed in such a way that both side parts of a support element projecting beyond the longitudinal supports are pivoted downwards essentially simultaneously upon loading of the spring slats, irrespective of whether the loading of these spring slats occurs in the middle region or in an edge region. This is achieved by the side parts being held in bearings which are fastened to the longitudinal supports, and by the two side supports being connected to one another by means of bridge elements, wherein this connection is designed to be movable, resulting in common mutual pivoting of these bridge parts. Optimum lying comfort is achieved on this mattress due to this design of the support elements, wherein, even if a person lies on a lateral region of this mattress and the corresponding support element is deflected, there is no inclination of the spring slats towards this side region of the mattress as the deflection is also transmitted to the other side part via the bridge elements and their connection.
Such a mattress base is also intended to offer corresponding lying comfort for persons of different weight. Adjustment possibilities are provided for this purpose and by means of which the deflection or the hardness of the deflection may be adjusted in order to be able to adapt it individually to the person lying on the bed.
The object of the present invention is therefore to provide a mattress base for a bed with adjustment means for the deflection or deflection hardness of the support slats, and which are simple in construction, are easy to operate, and whose effect is optimal. 2 irding to the invention, this object is achieved in that, in the region of the connection of no bridge elements, a leaf spring-shaped element extends substantially along the two e elements and may be pretensioned differently with respect to the bridge elements via »tment means. asy-to-produce adjustment device is obtained with this embodiment, wherein it is cost-tive, its mode of operation is very simple, and it may be adjusted in a simple manner, intageously, the leaf spring-shaped element is fastened on the lower side in the region 3 connection of the two bridge elements in the mounted state of the support slats on the tudinal supports, while the adjustment means are arranged between the bridge element the end region of the leaf spring-shaped element, wherein, in addition to favorable uction and assembly, aesthetic requirements are also fulfilled. 'ther advantageous embodiment of the invention consists in the leaf spring-shaped ent being fastened with a middle region to the bridge elements in the region of the ection, while the adjustment means are arranged at both end regions of the leaf spring-ed element. By increasing the distance between the two end regions of the leaf spring-ed element from the bridge elements via the adjustment means, the latter may be insioned in a simple manner. The deflection hardness of the support elements is thereby ased. intageously, the two bridge elements are connected to one another by a hinge and the spring-shaped element is connected in this hinge, enabling very simple construction and simple assembly of the corresponding elements. ther advantageous embodiment of the invention consists in the adjustment means being sd by an adjusting wheel that is rotatable about an axis of rotation which is fastened to »ridging element and which is aligned essentially parallel to the support surface for a ess, and is supported on the leaf spring-shaped element via a respective adjustment >n of the peripheral surface. This also results in a very simple design of the adjustment ;e. intageously, the adjustment regions of the circumferential surface 15 of the rotary wheel it different distances from the axis of rotation, as a result of which the pretensioning of eaf spring-shaped element may be increased or decreased by simply rotating the »ting wheel. 3
In order to enable optimum operation of the adjusting wheel for a user, this is arranged in a slot-shaped through hole in the bridge element and protrudes beyond the upper surface of the bridge element. As a result, the adjusting wheel may be rotated in a simple manner from the upper side of this mattress base.
In order to be able to correctly adjust the setting ranges of the adjusting wheel, the adjustment ranges of the adjusting wheel are defined with stops.
Advantageously, markings are applied to the adjusting wheel enabling the adjusted setting range to be displayed in a simple manner.
In order to improve operability, a radially-directed opening is provided on the adjusting wheel into which an adjustment tool may be inserted to adjust this adjusting wheel.
An embodiment of the invention is explained in more detail below by way of example with reference to the attached drawings:
Fig. 1 shows a perspective view of a section of a mattress base of a bed with the supporting element fitted and spring slats held in the holding means;
Fig. 2 shows a sectional view through the longitudinal supports and the supporting element placed thereon, with the leaf spring-shaped element inserted and the adjusting means located in a first position;
Fig. 3 shows a partial sectional view of the sectional view of Fig. 2;
Fig. 4 shows a sectional view through the longitudinal supports and the supporting element placed thereon, with the leaf spring-shaped element inserted and the adjusting means located in a second position; and
Fig. 5 shows a partial sectional view of the sectional view according to Fig. 4. A part of a mattress base for a bed is shown In Fig. 1. This comprises two longitudinal supports 1 and 2, which extend over the entire length of the bed. Support elements 3 are attached over the entire length of the longitudinal supports 1 and 2, one of which is shown in Fig. 1. These support elements 3 are aligned transversely to the longitudinal elements 1, 2 and are held in bearings 4, wherein the bearings 4 are attached to the longitudinal supports 1 and 2.
The support element 3 shown in Fig. 1 has two side parts 5 and 6, each of which protrudes beyond the longitudinal supports 1 and 2. 4
Each side part 5 and 6 is provided with a bridge element 7. The bridge elements 7 of the two side parts 5 and 6 are directed towards one another and are movably connected to one another at the two end regions remote from the side parts 5 and 6. In the embodiment shown here, this connection is designed as an hinge 8. The articulation axis 9 of this hinge 8 is aligned parallel to the longitudinal supports 1 and 2. The two side parts 5 and 6 with the bridge elements 7 are held pivotably in the bearings 4. The corresponding pivot axes 10 are also aligned parallel to the longitudinal supports 1 and 2. The possible pivoting movements of the side parts 5 and 6 with the bridge elements 7 will be described in detail later on. How a leaf spring-shaped element 11 is arranged below the two bridge elements 7 will also be described in detail below, wherein the leaf spring-shaped element 11 may be pretensioned differently via the adjustment means 12 with respect to the bridge elements 7.
The holding means 13 are mounted in a known manner at the end regions of the side parts 5 and 6 of the support element 3 protruding beyond the longitudinal supports 1 and 2, in which the spring slats 14, which form the support surface 15 for a mattress, are held.
Such adjustable support elements are used, in particular, in the middle region of a bed, at the head end and at the foot end of the bed; it is quite conceivable to use non-adjustable support elements that are constructed more simply.
The two longitudinal supports 1 and 2, the support element 3 with the side parts 5 and 6 and the respective bridge elements 7 may be seen in the sectional view in Fig. 2. The two bridge elements 7 are connected to one another by the hinge 8. The respective side part 5 or 6 with the corresponding bridge element 7 may be respectively pivoted about the bearings 4. The bearings 4 shown on the right-hand side in Fig. 2 allow a lateral movement of the side part 6 with the corresponding bridge element 7 in a known manner, in order to compensate for the change in the length of the support element during pivoting, as is described below.
If a force now acts on the spring slats 14, for example by a person lying thereon and as shown by the arrow 16, this causes, in particular when it acts in the lateral region of the side part 5 of the bed, this side part 5 to be pivoted downwards around the articulation 4, represented by the arrow 17. The pivoting of the side part 5 about the bearings 4 causes the bridge element 7 fastened to this side part 5 to be raised around the bearings 4, represented by the arrow 18. Due to the connection of the two bridge elements 7 via the hinge 8, the bridge element 7 is also raised as it is fastened to the side part 6, represented by the arrow 5 19. By this movement, the side part 6 is also pivoted downwards around the bearing 4, represented by the arrow 20. This means that the bearing surface 15 is always aligned horizontally, no matter whether and where a force is exerted on the spring slat 14.
In order to be able to elastically cushion the force acting on the support element 3, represented by the arrow 16, as may also be seen from Fig. 3, the leaf spring-shaped element 11 is pivoted around the hinge 8. The end regions 21 of this leaf spring-shaped element 11 interact with the adjustment means 12. These adjustment means 12 are each formed from an adjusting wheel 22, which is rotatable about an axis of rotation 23 supported on the respective bridge element 7. The adjusting wheels 22 shown here each have two regions 24 and 25, , which are formed from flattenings of the outer surface of the adjusting wheel 22, wherein each of these flattenings is at a different distance from the axis of rotation 23 of the adjusting wheel 22. In Fig. 2 and 3, the adjusting wheels 22 are each so adjusted that the region 24 is supported on the leaf spring-shaped element 11. This region 24 is at a greater distance from the axis of rotation 23 of the respective adjusting wheel 22, which means that the leaf spring-shaped element 11 is strongly pretensioned, which in turn means that a greater force is required to pivot the two bridge elements 7 in the direction of the arrows 18 and 19, which means that the hardness of the deflection of the support member is large. As may be seen from Fig. 4 and 5, the adjusting wheel 22 may be rotated about the axis of rotation 23 in such a way that the region 25 is supported on the leaf spring-shaped element 11. This region 25 is at a smaller distance from the axis of rotation 23 of the adjusting wheel 22 than the region 24, leading to the leaf spring-shaped element 11 being significantly less strongly pretensioned, while the deflection hardness of the support slat is also significantly lower, while the bed is thus adjusted to be "softer".
It is, of course, also possible to adjust the one adjusting wheel 22 so that the region 24 is supported on the leaf spring-shaped element 11, while the other adjusting wheel 22 is so adjusted that the region 25 is supported on the leaf spring-shaped element 11, as a result of which an average pretensioning of the leaf spring-shaped element 11 is achieved, which corresponds to an average hardness of the bed.
As may be seen from Fig. 2 to 5, the adjusting wheels 22 are each arranged in a slot-shaped through hole 26 in the bridge element 7 and protrude beyond the upper surface of the bridge element 7. 6
This arrangement enables the adjusting wheels 22 to be moved from the upper side of the mattress base, i.e. from the spring slat 14. In order to make visible the position of the adjusting wheel 22, markings 27 are applied to this as well as to the upper surface of the bridge element 7, as may be seen in Fig. 3 and 5.
The adjusting wheel 22 is provided with a radially-directed opening as shown in Fig. 2 and 4, into which an adjustment tool, e.g. a screwdriver, may be inserted in order to adjust the adjusting wheels 22, and which may be inserted between the spring slats 14 from above. The two side parts 5 and 6 are provided with stop elements 29, as may be seen in Fig. 2 and 4, which bear against the respective longitudinal supports 1 and 2 to limit the deflection when the bed is at maximum load.
Due to the fact that the adjusting wheels 22 have regions 24 and 25, which are designed as flattenings, the respective adjustment position of the adjusting wheel 22 is precisely defined. These flattenings thus act as stops, which determine the corresponding adjustment movement.
Of course, other adjustment means are also conceivable. For example, instead of the adjusting wheels 22, a wedge could be inserted, wherein the wedge could be inserted to a greater or lesser extent between the end regions 21 of the leaf spring-shaped element 11 and the respective bridge element 7.
Of course, it is also conceivable to provide more regions on the adjusting wheel than the two described areas 24 and 25, wherein the possibilities for adjustment are increased. It is also conceivable to provide the adjusting wheel 22 with an eccentric region, as a result of which a stepless adjustment of the pretension of the leaf spring-shaped element 11 would be possible.
The connection between the bridge elements 7 is designed as an articulation in the embodiment described above. Other means of connection are, of course, also possible, which would enable the bridge elements 7 to be pivoted together, for example, a leaf springshaped connection could be used instead of this articulation. A mattress base is obtained with this arrangement according to the invention, wherein the deflection hardness may be adjusted simply and effectively, leading to optimum lying comfort.
