Definitions

• the present invention relates to a spring bridge for a mattress base designed as a spring bridge frame, as defined in the preamble of independent claim 1.
• Spring bridge gratings are used in a variety of designs as a spring base for an upholstery cover, for example a seat cushion or a mattress.
• the flexible mounting of the spring bridges has proven to be very useful, especially for beds with a high level of comfort and good health.
• Flexibility results from the arrangement of several spring elements on a main support bridge.
• spring bridge gratings can be constructed, which - in interaction with the mattress - adjust optimally to a lying body, because of its nature and lying position locally with very different and constantly changing tracking power.
• the spring bridge accordingly comprises a main support bridge and at least one flexible support element which is arranged on it and has a flat design.
• the main support bridge can be mounted on the side parts of a bottom mattress and thus ultimately takes the load.
• the support element extends in the lateral direction transversely to the longitudinal axis of the main support bridge and, at least in part, over the top of the main support bridge. It is designed to be more flexible and / or more elastic than the main support bridge itself.
• the support element is preferably designed in such a way that it is bent downwards when loaded by a contact force (normally the locally acting weight of a mattress placed thereon and a person resting on it), with an area closer to the main support bridge being at an angle of at most the same size how to rotate a more distant area.
• the support element has the shape of a wing-like lip which extends obliquely upwards from the main support bridge. At least one support element is expediently arranged on each of the two longitudinal sides of the main support bridge.
• the flexibility of the support element is softer than that of the main support bridge, it deforms even under light loads, while the main support bridge only yields when the load is greater. In other words, there are different, additive load capacities and thus progressively adapting spring properties.
• Spring bridges designed according to the invention thus have in themselves the spring properties and resilience necessary for comfortable lying transversely to the longitudinal axis of the spring bridge.
• the flexibility or elasticity of the support element with respect to the main support bridge can be suitably adjusted by a suitable choice of material and cross-sectional dimensions. As experiments have shown, it is usually for a bed under mattress fits a person of normal weight if the support element can be pressed down to the level of the top of the main support bridge with a local contact force of about 20 Newtons (2 kilopond).
• the support element can be divided into a plurality of segments in the longitudinal direction of the spring bridge, or a plurality of support elements can be arranged in segments, whereby the locally differently adaptable spring action is further improved.
• Preferred embodiments of the support elements and the main support bridge are designed such that they can be assembled without tools and are suitable for self-assembly.
• the main support bridge and support element are expediently and preferably made of plastic, either in one piece or as separate parts.
• One-piece designs save additional fastening devices and assembly steps.
• separate parts there is the possibility of using different materials, for example materials with different elasticity or, for example, a glass fiber reinforced plastic for the main support bridge.
• separate parts ensure easy material separation during later disposal.
• a plurality of separate support elements can also be provided on a main support bridge. This advantageously allows the support elements to be arranged variably, for example in the case of spring bridges in the areas of greater load (for example in the buttocks section) more than in the areas of lower load.
• FIG. 1 shows a sketch of a spring bridge grate with spring bridges according to the invention
• FIG. 2 shows a perspective illustration of an exemplary embodiment of a spring bridge according to the invention, broken off to the rear in the longitudinal direction of the spring bridge;
• Fig. 3 is a front view of the spring bridge of Figure 2, with a schematic indication of different bending positions - the support elements and the main support bridge and
• FIGS. 1 to 3 show the basic elements of the invention.
• a number of spring bridges 2 for forming a bottom mattress are mounted in a frame, here consisting of two longitudinal frames 4.
• Each spring bridge 2 consists of a main support bridge 6, which is designed as a hollow section bar with an essentially rectangular cross section, and two support elements 8 each arranged on a longitudinal side of the main support bridge 6.
• the support elements 8 are formed on the main support bridge 6 and extend in the form of a flat, wing-like lip from the main support bridge in the lateral direction transversely to its longitudinal axis at an angle upwards and, with the exception of its part directly adjoining the main support bridge 6, protrude beyond the top of the main support bridge. Because of their flat design and small thickness, the support elements 8 have a comparatively great flexibility or elasticity with respect to the main support bridge 6, which is in any case softer than the flexibility or elasticity of the hollow profile of the main support bridge.
• the support elements 8 are bent and pressed down to the level of the top of the main support bridge and possibly further downward, as indicated by the different positions along the arrows A in FIG. 3, while the main support bridge 6 yields only slightly (arrow B). Only when the contact force is greater and after depressing the support elements 8 can also act directly on the main support bridge 6, is the latter also deformed more.
• the support element on one side of the main support bridge can be pressed further down than that on the other side, which results in an overall contact surface that is inclined with respect to the horizontal, and the spring bridge is tilted to a certain extent in an articulated manner in its effective position.
• FIG. 4 generally corresponds to that described above.
• the two support elements are formed by recesses 10 in the longitudinal direction of the spring bridge divided into several segments 12. They can therefore adapt locally to an even greater extent.
• FIGS. 5 and 6 show spring bridges in which the support element and main support bridge are separate parts.
• the main support bridge is a hollow profile rod 14, for example made of glass fiber reinforced plastic, with a longitudinal slot 16.
• the longitudinal slot 16 and the wall webs 18 adjoining it form an undercut groove into which the retaining web 20 or 22 formed on the respective support element can be inserted.
• two wing-like lips 24 are combined to form a single, flat V-shaped support element, while in FIG. 6 a plurality of wing-like support elements 26 are arranged in segments in the longitudinal direction of the spring bridge.
• the support elements 26 can be inserted in different arrangements, for example — as shown — mutually aligned or all on the same side or in groups on one side and then again on the other side, for example two on the left, two on the right, etc. Likewise, the distances can be adjusted choose freely between the support elements, so that such a design offers many possibilities for variable design of the spring bridge.
• FIGS. 7 to 12 show further constructive variants of a spring bridge according to the invention.
• the main support bridge is designed as a profile bar 28 which is folded several times in the transverse direction and on the lateral outer webs a wing-like support element 30 is formed in each case.
• the multiple folding of the profile bar 28 is useful in two respects. On the one hand, the multiple folding improves the Load capacity of the main support bridge in the longitudinal direction, on the other hand the main support bridge can be deformed to a certain extent in the transverse direction via a contact force acting on the support elements and thus makes an additional contribution to the spring properties of the support elements.
• the main support bridge consists of a solid rod 32 with a slightly trapezoidal cross section, which is provided with two longitudinal bores 34.
• Two wing-like support elements 36 combined into a flat V-shaped part are attached to the top of the main support bridge via a web 38 serving as a spacer.
• This arrangement advantageously enables an additional gradation in the spring properties of the support elements. If the support element 36, which is spaced above the rod 32, is loaded with a contact force, it hits the rod 32 with its underside after a first partial deflection. For the further deflection, the bending distance is thus shortened and thus the flexibility of the support element is reduced.
• flat, slightly upwardly curved support elements 42 are formed laterally on a hollow profile bar 40 serving as the main support bridge, which support elements on their longitudinal edge j e, which are remote from the hollow profile bar 40, have a flat, essentially horizontally extending support element 44.
• the top of the hollow profile rod 40 is widened by laterally projecting webs 46.
• the spring bridge shown in FIG. 10 also has a hollow profile bar as the main support bridge, here with 4 8 b e- records.
• Two lips 50 which extend outward on one of the two longitudinal sides of the hollow profile rod 48, are formed on the latter, each of which has an upwardly projecting spring element 52 in the form of a flexible V profile on its outer edge.
• the two spring elements 52 in turn support a flat support element 54.
• the spring properties advantageously result from the interaction of the different elasticity of the support element 54, the spring elements 52, the lips 50 and the hollow profile rod 48.
• a support element or a support 63 here dimensioned comparatively over a large area, is connected to a snap-on profile which has an approximately U-shaped cross section.
• the snap-on profile has a rather flat surrounding part 64.
• this part 64 The elastic properties of this part 64 are matched to those of the snap edges 61, so that problem-free clipping and reliable attachment of the support 63 to the profile bar 60 is possible.
• supports 63 can be freely cantilevered or large-area and can be connected to a plurality of profile bars 60, optionally in only partial or partial fashion. tial way.
• the required ventilation of the top mattress is supported by the shape of the ventilation openings 59.
• the elasticity behavior of the pad 63 can hereby be adjusted.
• Individual snap-on elements can also be attached to the spring bridges using the snap connection mentioned.
• support elements 63; 64; 65; 66; 67; 68 mutually offset or clipped onto the spring bridges or profile bars 60 in the immediate vicinity, so that a locally different elasticity behavior of the base mattress can be set according to individual specifications.
