Definitions
- the invention relates to a spring element according to the preamble of claim 1 for use in a Underbed and for laying mattresses, cf. AT-B-383 260.
- underbeds for insertion in existing bed frames known in a wide variety of configurations. So are in the The past in particular underbeds in the form of slatted frames have been used, each transverse to the longitudinal extension bed slat arranged along its length has a certain elasticity, so that to some extent a spatially different cushioning for those on the Bed lying person is possible.
- a lower bed In order to achieve a specific elasticity of a lower bed, a lower bed has already been proposed (DE-197 00 130-A1), which serves to support a mattress and has a multiplicity of support elements arranged flat, each a support plate for the mattress and at least contain a spring element carrying the support plate, that is supported on strip-like abutments.
- the spring elements each supported on two abutments and extend between the abutments downwards so that at least partial areas of the spring elements are between the abutments. Will by a certain area of the person lying on the bed of the lower bed, so that in this area Spring elements arranged in the lower bed below the mattress give way elastically.
- the disadvantage is, however, that the spring elements are essentially only vertical to the lying surface, i.e. can move perpendicular to the mattress.
- the structure of these known elements is very consuming.
- Other, but correspondingly complex designs show e.g.
- the object of the invention is to provide a solution with which has a specific elasticity of a lower bed with a elastic compliance in any direction the least possible effort can be achieved.
- a spring element according to the invention thus consists of three Parts, namely from one with the supporting structure of the lower bed connected support ring, a penetrating this and upwardly projecting spring body as well as from a spring, which the resilient link between the support ring and the spring body. Because of this design the spring body can not only cross to the lying surface move, but in any direction so that a optimal adaptation to the lying position or the movements possible for the person on the associated bed is.
- the spring element according to the invention is because it only consists of the three parts mentioned above, quite simple manufacture.
- the spring element can then be used to mount the spring element from below into the shoulder of the support ring like this be introduced that the supporting webs of the spring body in the guide slots of the support ring are guided. following the ring spring is inserted and holds the spring body in a certain rest position on the support ring. against the power of Ring spring can then the spring body in any angular orientation pressed elastically into the support ring become.
- the spring can advantageously be designed as a rubber ring spring be, with the supporting webs of the spring body on the Put on the rubber ring spring. It is also in configuration possible that the spring arranged on the support ring after resilient tongues pointing below.
- the spring properties of the spring element can still thereby be further improved that in the position of use downward-facing area of the support ring with a Pot-shaped bottom equipped to form an air chamber is.
- the spring body of the spring element can in principle be any Have shapes, is advantageously provided To design the spring body as an elastic ball or ball, but also essentially hemispherical or on the top slightly flattened, i.e. the spring body is then a spherical cutout with a flattened surface facing the mattress educated.
- the spring body with a perforation to allow air to pass through towards the mattress to be placed over it is.
- a spring element 1 according to the invention for use in one There is essentially a bed and mattress support of three parts, namely a support ring 2, which in the supporting structure of the lower bed can be installed, one the support ring 2 penetrating centrally, the upper surface outstanding spring body 3 and a spring body 3 on the support ring 2 fixing ring spring 4, which preferably as Rubber ring spring is formed.
- the support ring 2 has one in the use position down pointing cylindrical shoulder 5, which in the embodiment is provided with three guide slots 6. Further in this embodiment, the support ring 2 still an outer circumferential shoulder 7 for fastening the support ring 2 in the supporting structure of the lower bed. Moreover has the shoulder 5 of the support ring 2 to the outside Pointing cams 8 on the lower edge, which are used for support the ring spring 4 serve.
- the spring body 3 is essentially hemispherical and has a lower cylindrical region 9 on, the lower edge with outward-pointing supporting bars 10 is provided, which are designed such that they in the assembled position in the guide slots 6 of the shoulder 5 of the support ring 2 are guided.
- FIG. 3 shows the spring body 3 from below in the direction of the arrows 11 in the cylindrical shoulder 5 of the support ring 2 such introduced that the supporting webs 10 in the guide slots 6th be included. Then the ring spring 4 becomes such pushed over the cylindrical shoulder 5 of the support ring 2, that they are on the one hand between the cams 8 of the support ring 2 and on the other hand between the supporting webs 10 of the Spring body 3 is held.
- the spring element 1 is thus fully assembled, as shown in Figs. 1 and 2 as well the upper representation of Fig. 3 is shown.
- Fig. 4 shows the rest position of the spring element 1. In In this position, the spring body 3 is not deflected downwards.
- Fig. 6 shows an embodiment of an inventive Spring element 1, which is different from those described above Embodiments differentiates that in the Area of use of the support ring facing downwards 2 with a cup-shaped bottom 12 to form an air chamber 13 is equipped. This allows the suspension properties improve the spring element 1 even further. It can be provided that the spring body 3 with a perforation to allow air to pass through towards the mattress to be placed over it is.
- the lower bed is designed as a continuous plate 17, which are provided with holes in which the support rings 2 of the spring elements 1 are used.
- FIG. 9 largely corresponds to that 8, but here is not a single one Plate 17 provided, but the lower bed is from several plates 18 are formed, which can be pivoted to Formation of a head or foot section connected to each other could be.
- the spring element 1 shown there consists of a Support ring 2 with downward, forming the spring 4, integrally molded spring tongues 4a, from above the elastic body 3 forming elastic ball or a ball is used.
- the assembly is shown in FIG. 12, a bottom view is shown in Fig. 11.
- the spring body 3 forming ball can be made of different materials each be formed according to the desired hardness, it can be a hollow body be trained in half-shell construction, such as indicated in Fig. 10, the different here too Degree of hardness through different colors or one different surface designs can be.
