Definitions

  • the invention is in the field of furniture manufacturing and relates to a supporting grate according to the first independent claim for seating or reclining furniture, in particular for beds, and support elements, in particular slats, for such a supporting grate according to the corresponding independent claim.
  • supporting gratings are used as load-bearing elements for beds.
  • the gratings consist, for example, of slats, which are themselves resiliently or stiffly attached to a bed frame or on longitudinal spars of such a frame or are resiliently mounted and span across the bed in a prestressed or relaxed state.
  • a mattress is placed on the slatted frame and the slatted frame and mattress together form the load-bearing and springy support on which a person can sit or lie comfortably, the slatted frame taking on more of the load-bearing function, the mattress more of the elastic, adapting to a body contour .
  • the slatted frame must have a minimal mechanical strength, but should advantageously be resilient to a limited extent at the same time.
  • slatted frames the slats of which are firmly attached to at least two spring bodies running parallel to the longitudinal axis of the bed, for example beam-shaped bodies made of an elastic material such as latex, show very good spring properties.
  • the spring bodies then rest on the longitudinal bars of a bed frame or can also be placed directly on the floor.
  • the spring bodies allow the slats to move in the vertical direction when the grate is loaded, and limited pivoting movements about their longitudinal axis.
  • Slatted frames that are based on this principle are commercially available, for example, under the brand names "Liforma” and "Marmotli” and show very good spring and adjustment properties, so that they can be used comfortably with very thin mattresses.
  • narrower slats provide greater comfort than wider ones, i.e. with a minimum of effort only a comfort that is already high but also limited can also be achieved and that this comfort could still be improved with narrower slats.
  • the invention now has the task of realizing such an improvement to greater comfort, but without the additional expense of the narrower slats (supporting elements), that is to say to create a supporting grate for a piece of seating or reclining furniture, in particular for a bed, while maintaining the same Width of the support elements offers greater comfort, even if the support elements are fastened or stored in a very simple manner.
  • the supporting grate according to the invention consists of a large number of supporting elements, for example made of wood, that is to say of slats.
  • the supporting elements are called slats in the following description, but they can also consist of materials other than wood, for example plastic, bamboo canes, etc.
  • the supporting grate according to the invention is based on the slatted frame already mentioned above, in which the slats are stiff or have little resilience and are attached to at least two spring bodies.
  • the slats of the supporting grate according to the invention do not have a substantially rectangular cross-section, as in the known slatted frames, and are fixedly attached to the spring bodies, but are shaped and attached in such a way that they can move relative to the spring bodies, to a limited extent Pivotal movement about a pivot axis which is substantially parallel to its longitudinal axis.
  • the cross section of the slats of the supporting grate according to the invention shows a swing profile at least in the area of the support of the slats on the spring bodies, i.e. the side of the cross section of the slats facing the spring bodies has a profile in which the middle area (support area) is further away from a straight line connecting the narrow sides is as the outside areas.
  • the swing profile is, for example, an arc, the center of the circle being above the center of the slat.
  • the swing profile is advantageously designed in such a way that the crossbar, when it lies freely on a flat support surface with the swing profile directed downwards, rests in an unstable equilibrium on its central area (support area or support edge) in a position symmetrical to the perpendicular bisection of the cross section of the crossbar.
  • the slat with a swing profile preferably has a thickness in the range from 5 to 20 mm.
  • slats (support elements) with such a rocking profile are now fastened with a movable fastening in the middle regions (support region or support edge) resting on the spring bodies in such a way that they are pivoted about the fastening by the pressure acting asymmetrically to their central perpendicular to the spring bodies .
  • Figures 1 and 2 show an exemplary embodiment of the supporting grate according to the invention in section, namely parallel to the slats ( Figure 1) and cut transversely to the slats in the region of a spring body ( Figure 2).
  • the supporting grate according to the invention consists of a large number of slats (supporting elements) 1 which are not or only very slightly resilient per se and at least two transversely to the slats extending elastic spring bodies 2, for example beams made of latex, the slats being fastened to the spring bodies.
  • the attachments 3 of the slats to the spring bodies are indicated schematically in FIG. 2. As can be seen from FIG.
  • the slats 1 of the embodiment shown have a swing profile in cross section, that is to say their side facing the spring body only lies on the spring body in a central region (contact area or contact edge) and is fastened to it in such a way that the crossbar 1 can be pivoted relative to the spring body 2 to a limited extent about the fastening 3.
  • Figures 3 to 6 show different, exemplary swing profiles for slats (support elements) for the support grid according to the invention.
  • Figure 3 shows the staff of Figures 1 and 2 on a larger scale.
  • the swing profile consists of a circular arc, the center of which is above the staff on the central perpendicular of the staff cross-section.
  • the swing profile need not be an exact circular arc, it can also be another convex arc, which is advantageously symmetrical with respect to the perpendicular perpendicular M of the crossbar.
  • Figure 4 shows as a swing profile part of a polyhedron, also convex and advantageously symmetrical to the perpendicular M of the crossbar.
  • Figure 5 shows a simple swing profile, which consists of two inclined lines that essentially form a support edge in the central area of the crossbar.
  • Figure 6 shows a support element which is not a slat in the narrowest sense of the word. It is a bamboo tube or other tube 13 which is divided lengthwise (for example divided in half) and which is filled with a suitable filling material 14, for example latex.
  • the upper surface of the slats of the supporting grate according to the invention, facing away from the spring body, can be of any shape per se. It is advantageously designed as a flat surface and rounded off against the swing profile. As already mentioned above, it is sufficient if the crossbar only has a swing profile where it rests on the spring bodies. However, since it is simpler in terms of manufacturing technology to create the swing profile over the entire length of the slat, the slat will advantageously have the same cross-sectional profile over its entire length. Once the manufacturing tools have been set up for the production of a swing profile, the production of such slats is no more complex than the production of slats with an essentially rectangular cross section.
  • the fastening of the slats to the spring bodies must be such that the slats can be pivoted with respect to the spring bodies as freely as possible, that is to say by applying the smallest possible forces.
  • Such a pivoting movement of the crossbar is only possible if the fastening and / or the part of the spring body to which it is fixed is sufficiently flexible. Since the spring bodies consist of an elastic material (latex) and are usually surrounded by a fabric cover, this area is sufficiently flexible. For an even greater pivoting option, however, an additional self-flexible slat attachment is recommended.
  • FIGS. 7 to 10 show two exemplary embodiments of slat fastenings, each as a view across a slat (FIGS. 7 and 9) and as a cross section through a slat (FIGS. 8 and 10).
  • the two embodiments of slat fastenings both have two buttons (31, 33) per slat and spring body, which are in buttonholes Insert one tab 41 each, the tabs 41 running along the two edges of the spring bodies 2 facing the slats.
  • the tabs can, as shown, be parts of a tissue envelope 4 completely surrounding a spring body, but they can also be fastened to the corresponding edges of the spring body in another suitable manner. Attachment on both sides of the spring body is advantageous, but not absolutely necessary. As such, one-sided fastening in the same way could also be provided.
  • the button 31 is formed or fastened to a dowel 32 via a neck 31 ', the dowel 32 being embedded and glued into the crossbar.
  • the button 33 is connected to a counter button 34 via a stiff or elastic neck piece 35, the counter button 34 sitting on the top of the crossbar 1 and the neck piece 35 being guided through an opening 11 leading through the crossbar . If the neck piece 35 is stiff, the button 33 or the counter button 34 must be placed on the neck piece 35 during assembly. However, if the neck piece 35 is flexible, the buttons 33 and / or 34 and the opening 11 leading through the crossbar can be provided such that one of the buttons can be guided through the opening 11 at an angle, for example.
  • Simpler variants of the slat fastenings shown in FIGS. 7 to 10 consist in that the slats are fastened directly to the tabs 41 with the aid of at least one nail, one screw, one clamp or one rivet. These variants are readily conceivable for the person skilled in the art and are therefore not illustrated by figures.
  • FIGS. 11, 12 and 13 show a further exemplary embodiment of a slat fastening, which is also based on an interaction of a button (36.1, 36.2) with a buttonhole in a tab 41 on each side of the spring body 2.
  • the two buttons 36.1 and 36.2, with which a slat 1 is fastened to a spring body 2 or to the tabs 41.1 and 41.2 running along the edges of the spring body, are connected to one another with a flexible, elastic or inelastic band 37.
  • the band 37 runs in a slot 12 running on the top of the slat and through two openings 11.1 and 11.2 leading through the slat.
  • buttons 36.1 and 36.2 are, for example, rod-shaped, as shown, so that they can be easily guided through the openings 11.1 and 11.2 for assembly in an angled position. If the band 37 is not elastic, at least one of the buttons 36.1, 36.2 must be attached to it during assembly.
  • slat fastenings are possible as long as they meet the condition of the pivoting of the slat relative to the spring body.
  • the illustrated and described embodiments all have the advantage that they can be easily produced from natural materials such as solid wood, cotton, latex, etc.
  • the slats with the swing profile are also advantageously made from solid wood, so that the supporting grate according to the invention not only fulfills the task in terms of manufacturing economy, but can also meet high ecological demands.
