Definitions

  • the invention relates to an elastic support element, in particular to support a mattress of a bed, with a base body, a support plate and a spring element arranged between the base body and the support plate.
  • the invention further relates to a spring element of such an elastic support element and a bed frame with such support elements.
  • An elastic support element of this type is known, for example, from European patent application EP 0 734 666 A1. With such an elastic support element, however, the spring elements used for this purpose offer sufficient deformability only in one direction relative to the vertical without being damaged.
  • an elastic spring element is known from WO 94/07395, which has a truncated cone-shaped structure and comprises several individual struts.
  • this spring element is disadvantageous in that the individual struts tend to bulge sideways or even break off when the pressure is applied obliquely. A safe long-term use can not be guaranteed by such spring elements.
  • the invention is therefore based on the object of improving an elastic support element of the type mentioned in such a way that its durability is increased and safe long-term use can be ensured.
  • the invention is also based on the object of specifying a spring element for supporting elements for use in bed structures and a bed frame with such supporting elements.
  • an elastic support element of the type mentioned at the outset in that the spring element has a support ring from which a plurality of spring struts extend radially outward.
  • an elastic support element in particular to support a mattress of a bed, is created according to the invention, in which all individual spring struts are coupled to one another by a central support ring in the middle of the spring travel, as a result of which individual spring struts can be bent out laterally and safely is permanently prevented.
  • the elastic support element receives a simple structural structure which consists of only a few parts, whereby the production costs can be reduced and the production capacities can be increased.
  • the upper support plate of the elastic support element on which the mattress rests is not designed as a rigid plate, but which is composed of a plurality of concentric ring elements which are connected to one another by means of a plurality of radial support elements which strive radially outward, an elastic support of the mattress is further ensured, which contributes to a further increase in sleeping comfort.
  • the spring element can be cast in a state in which the spring struts protrude radially flat from the support ring, casting molds can be used, the upper and lower shells of which only have to be machined to a small depth. This significantly reduces the tool costs and thus the total manufacturing costs of the elastic support element.
  • a complete mattress pad can be inexpensively manufactured, which due to its high point elasticity ensures optimal support of the body both in the side position and in the supine position.
  • Fig. 5 is a view of the same spring element in a position which is approximately the
  • the arrangement of the spring element corresponds to how it is removed from the mold
  • FIGS. 1 and 2 shows a base body of the elastic support element shown in FIGS. 1 and 2 in an oblique view from above
  • FIGS. 6 and 7 are side views of the base body shown in FIGS. 6 and 7,
  • FIGS. 6 to 8 are plan views of the base body shown in FIGS. 6 to 8,
  • FIG. 10 is a support plate of the elastic support element shown in FIG. 1 obliquely from above,
  • Fig. 12 is a side view of the platen shown in Figs. 10 and 11, and
  • Fig. 13 is a plan view of the platen shown in Figs. 10 to 12.
  • an inventive elastic support element which serves in particular to support the mattress of a bed, is numbered 1.
  • reference numeral 2 designates a lower base body on which a spring element 4 can be placed.
  • a support plate 3 can be placed on this spring element 4 so as to form the complete elastic support element 1.
  • a mattress (not shown) then rests on a large number of spring struts constructed in this way and arranged next to one another, which is supported and supported at points by the individual spring elements.
  • the spring element 4 arranged between the base body 2 and the support plate 3 determines the total height of the elastic support element by the length of its spring struts 6a, 6b.
  • the spring element 4 is made of plastic, preferably of the material "hightrel", the choice of material having a significant influence on the overall rigidity of the spring strut.
  • the strut is constructed as follows, as shown in FIGS. 3 to 5. Starting from a central, preferably annular support ring 5, which has the shape of a flat disk of constant thickness, a plurality of spring struts 6a and 6b extend radially outward.
  • the number of struts is variable, but always an even number.
  • two groups of six suspension struts are alternately arranged on the outer circumferential side of the support ring 5.
  • the number of struts and their individual strength (thickness) also affects the rigidity of the elastic support element.
  • the spring element 4, which consists of the carrier ring 5 and an even number of struts 6, is produced in one piece by injection molding.
  • the injection mold can be manufactured in such a way that the spring struts 6 extend flat radially outward from the outer peripheral side of the carrier ring 5. Since the spring struts 6 preferably have a smaller thickness than the carrier ring 5, and since the carrier legs 6 can be manufactured by means of injection molding in a state in which they lie in the plane of the carrier ring 5, a casting tool can be used for this purpose, which is only one Has upper shell and a lower shell without further cores or additional parts.
  • Fig. 4 shows the spring element 4 in a relaxed state in which it reaches its maximum height and in which it can be assembled with the base body 2 and the support plate 3, so as to the elastic support element 1, as shown in Figs. 1 and 2 is shown.
  • the struts 6 are divided into two groups, the struts which are angled downward from the support ring with the reference numeral 6a, and the struts of the group which are angled upward, bear the reference number 6b.
  • a suspension strut from group 6a and a suspension strut from group 6b are alternately arranged along the outer circumference of the support ring 5.
  • a single shock absorber of group 6b is structured as follows, as can be seen from FIGS. 3 to 5:
  • an inner elastically deformable section 7b extends flush with the flat upper side of the carrier ring 5 to an adjoining inner dimensionally stable section 8b.
  • This inner dimensionally stable section 8b is coupled to an outer dimensionally stable section 10b by a middle elastically deformable section 9b.
  • outer dimensionally stable section 10b there is an outer, elastically deformable section 11b, which connects it to a further section of the spring strut 6b, which is designed as a coupling element 12b, and through which the spring strut 6b can be coupled to the support plate 3.
  • the spring strut has a constant width over its entire length (from the inner elastically deformable section 7b to the outer elastically deformable section 11b.)
  • the spring strut 6b has a thickness which is less than or equal to the thickness of the carrier ring 5, preferably corresponds to half its thickness, It is also possible to make the coupling region 12b thicker than the dimensionally stable sections 8b and 10b.
  • the elastically deformable sections 7b, 9b and 11b each have a smaller thickness than the dimensionally stable areas.
  • the spring strut when viewed from the side of its thickness, has a semicircular notch or recess in the region of the elastically deformable sections.
  • This recess can also have the shape of a cylinder segment or a round notch.
  • the recess is formed on the upper side of the spring strut 6b, that is to say on the side facing the support plate 3 or in the position of the spring element 4 shown in FIG. 4, towards the center of the support ring 5 shows, whereas the recess of the elastically deformable region 11b is formed on the opposite side (outside or underside) of the spring strut 6b.
  • each upper strut 6b that is from the side which is the furthest away from the support ring 5, a central notch is formed towards the support ring 5, which divides the coupling region 12b and the outer elastically deformable section 11b into two equally large side sections , Their width corresponds approximately to the thickness of the coupling area 12b.
  • Each of these two lateral sections of the coupling area 12b is hook-shaped, the hooks being oriented in the opposite direction in the plane of the shock absorber, so that they can be inserted into the coupling eyes or receiving eyes of the support plate 3 by slightly compressing them, and the spring element 4 in the support plate 3 anchor, but can be separated again from the support plate 3 by a further compression.
  • both the hooks on their outer opposite end face and the eyelets on their inner end face have corresponding bevels.
  • the structure of the lower support legs 6a corresponds exactly to the upper support legs 6b, only that, as shown in FIG. 5, they are arranged on the support ring 5 in the opposite orientation.
  • the recesses in the case of elastically deformable sections 7a and 9a point to the underside, that is to say to the base body 2, or in FIG. 4 also to the center of the spring element 4, whereas the outer elastically deformable sections 11a are arranged on the outside of the spring struts 6a ,
  • the coupling elements 12b correspond to the coupling elements 12a and engage in eyelets 17 of the base body 2, which correspond to the eyelets 15 of the support plate 3.
  • the struts 6a and 6b in a state in which the elastic support member is compressed, i.e. by applying a force along a central central axis Z to the elastic support member, a V-shaped shape, wherein the "Tip" of each V is formed by the elastically deformable sections 9a, 9b, and the two arms of the V are formed by the dimensionally stable sections 10a, 10b and 8a, 8b, respectively.
  • the coupling sections 12a, 12b are aligned in each state of the assembled elastic support elements parallel to the respective receiving eyes 15 and 17 in the support plate 3 and the base body 2, respectively.
  • the base body 2 is shown in detail in FIGS. 6 to 9. It essentially consists of a preferably round, flat disc which has a central central opening.
  • a support collar 16 is formed around the central opening, which has the shape of a hollow cylinder and extends vertically in a ring shape from the top of the flat disk.
  • the average diameter of the support collar 16 corresponds approximately to the average diameter of the support ring 5 of the spring element 4. It serves to limit the compression of the elastic support element, in particular of the lower spring struts 6a. This prevents the elastically deformable sections of the spring struts 6a from being overstretched.
  • a plurality of receiving eyes 17 for receiving the coupling elements 12a of the spring struts 6a of the spring element 4 are formed in a ring around the support collar 16. These receiving eyes 17 essentially resemble a cuboid-shaped attachment which is cast onto the flat disc, with a central opening which is matched to the size of the coupling elements 12a.
  • the base body 2 which is preferably designed as a circular flat disc, at least two peg-shaped fastening elements 18 are formed, by means of which the elastic support element 1 can be mounted on a support frame.
  • the fastening elements 18 are essentially cylindrical and have ring knobs on their outer circumference.
  • the number of fastening elements 18 is preferably two, so as to enable fastening of the elastic support element on individual lath-shaped struts of a carrier frame. However, it can also be three or more.
  • the number of receiving eyelets 17 corresponds to the number of spring struts 6a of the spring element 4.
  • the support collar 16 is arranged approximately halfway between the outer peripheral surface and the central bore of the base body 2.
  • the fastening elements 18 are arranged below the support collar 16.
  • the support plate 3 is essentially flat upwards. However, seen from above, that is to say in the direction of the Z axis, a central central axis which is perpendicular to the upper plane of the receiving plate 3, the support plate 3 is composed of a plurality of concentric ring-shaped or polygonal ring elements 12 which are spaced apart from one another.
  • the upper support plate 3 can also be designed such that several, preferably three or four further concentric rings 12 extend around a round central disc, which may have a central through opening, around which a further disc-shaped plate 20 is arranged, which is arranged on it
  • the inside is circular and the outside is round or approximately square.
  • an additional stiffening collar 19 can be formed on the underside of its outer edge.
  • the individual sides of this polygon can be slightly curved outwards and the corners themselves can be rounded.
  • the individual ring-shaped or polygonal ring elements 12 are connected to one another and to the inner pane and the disk-shaped plate 20 by means of a plurality, preferably four, radially outwardly extending support elements 13. These are elastically deformable at least in the direction of the Z axis.
  • the support plate 3 By such a design of the support plate 3, not as a solid, contiguous plate element, but according to the embodiment described above, in which several concentric support elements are connected by support struts or radial support elements 13, the support plate 3 itself becomes an elastic support plate. This can flexibly adapt to a point load applied by the mattress, which lies next to the Z axis, by tilting or resiliently lowering its individual elements. This further increases sleeping comfort considerably.
  • the configuration of the support plate 3 by means of individual ring elements 12 spaced apart from one another also ensures the ventilation of the mattress in the area of the support surface.
  • the diameter of the support plate 3 is preferably approximately twice to three times the diameter of the spring element 4 in its relieved position. A different diameter ratio is conceivable at any time.
  • a collar 14 corresponding to the support collar 16 of the base element 2 is arranged on the underside of the receiving plate 3 around the central through opening.
  • This collar 14 also has an average diameter which corresponds to the average diameter of the support ring 5 of the spring element 4. He prevents the elastic support element 1 from being compressed too much and thus prevents the upper spring struts 6b of the spring element 4 from being overstretched.
  • Receiving eyes 15 for the coupling elements 12b of the spring struts 6b of the spring element 4 are formed in a ring around the collar 14. Their number corresponds to the number of struts 6b.
  • all the receiving eyelets 15 are arranged in their own annular approach arranged on the underside of the support plate 3. However, they can also be designed in accordance with the receiving eyes 17.
  • the individual elements of the elastic support element, the base body, the support plate and the spring element are preferably each formed in one piece from highly elastic plastic by means of injection molding.
  • Production is preferably carried out from “hightrel” in order to ensure the desired spring action of the spring element 4 over a long period of time.
  • a connection of the individual components to one another is of course possible at any time by modifying the coupling elements.
