Definitions

  • the invention relates to a slatted frame for beds, consisting of a rectangular frame with parallel to its short sides spaced transverse slats, the respective ends of which are connected to the respective longitudinal member of the frame via a leaf spring.
  • Slatted frames for beds are known in a wide variety of embodiments.
  • the crossbars which are usually made of wood, can be designed to be self-resilient and connected rigidly or resiliently to the frame.
  • Numerous proposals are known for the spring-elastic connection, such as elastic rubber or plastic elements, helical compression springs, straight leaf springs and C-shaped curved leaf springs. The latter can be arranged either parallel to the crossbars or parallel to the side members of the frame.
  • the crossbars of slatted frames are to be fixed in their longitudinal direction so as to be secure against displacement, in the transverse direction, that is to say parallel to the longitudinal beams of the slatted frame, to a certain extent can be rotated and displaced.
  • the resilient connection of the crossbars to the frame is subject to the requirement that it is fatigue-free and overload-proof for a long time.
  • the spring elements that have these properties should also be inexpensive to manufacture and assemble.
  • leaf springs have an essentially linear spring characteristic, so that the slatted frame only has the desired spring hardness symmetrically to its longitudinal center line when it is loaded, but becomes increasingly softer and correspondingly deeper, the further the load compresses towards an edge relocated there.
  • the resulting "inclined plane" in the transverse direction of the slatted frame or the mattress lying thereon is highly undesirable.
  • the invention has for its object to provide a slatted frame of the type specified in the introduction, the crossbars are connected to the longitudinal frame via inexpensive to manufacture and easy to assemble spring elements that ensure a great security against displacement of the crossbars in their longitudinal direction, but at the same time a certain tilt and Allow transverse movement, are durable and have a strongly progressive spring characteristic to compensate for asymmetrical loads.
  • leaf spring is bent approximately SL-shaped, and is connected at its apex to the end of the crossbar and is supported with its two horizontal ends on the longitudinal member of the frame and is connected to it.
  • Such a leaf spring can be produced inexpensively from stainless steel spring sheet metal by bending and, in the simplest case, can be screwed on the one hand to the side member and on the other hand to the crossbar in question, so it can be assembled quickly and without additional parts.
  • the spring hardness can be changed with simple means using both the material thickness and the width.
  • the leaf spring allows only slight displacements of the crossbars in their longitudinal direction, but allows a certain mobility in the transverse direction, which can also be easily increased if the apex of the leaf spring is connected to the crossbar in a manner other than by means of screws.
  • the special shape of the leaf spring ensures a relatively high hardness with low material expenditure and for a strongly progressive spring characteristic which counteracts an undesirably wide deflection with one-sided loading of the mattress.
  • the slatted frame equipped with these springs is therefore inexpensive to manufacture, has the desired suspension properties and has a long service life.
  • the drawing shows a slatted base according to the invention and several embodiments of the leaf spring essential for its properties.
  • the slatted frame shown in Fig. 1 consists in a known manner of a wooden frame, of which only the two parallel longitudinal members 1a and 1b and a cross member 2 are shown here. Between the longitudinal beams 1a and 1b, crossbars 3, which are also made of wood, are usually arranged, which can also be convex if necessary. Each crossbar 3 is connected at its two ends to the relevant longitudinal member via an approximately ⁇ -shaped leaf spring 4.
  • the ⁇ -shaped leaf spring 4 is screwed to the crossbar 3 at its apex. Likewise, the two free ends of the leaf spring 4 are screwed onto a horizontal support surface on the side member 1a.
  • the longitudinal beam 1a has an L-shaped cross section; the vertical leg acts as a travel limit or stop and thus avoids overloading or leaf spring 4, which could lead to their breakage.
  • the leaf spring has 4 are connected by a uniformly convexly curved apex 4a, to which the essentially straight upper legs 4b, 4c, which are angled inwards on both sides in a narrow radius of curvature, run downward, and which are in turn angled outwards in a narrow radius of curvature and which are angled to the lower legs Connect 4d, 4e, which merge into the respective horizontal ends 4f, 4g with a wide radius of curvature.
  • the upper legs 4b, 4c are approximately as long as the lower legs 4d, 4e. It is essential that the leaf spring 4 has only relatively short sections running perpendicular.
  • the respective narrow radii of curvature are approximately one third or two thirds of the height of the unloaded spring.
  • the leaf spring 4 inherently has a high spring hardness taking into account its material thickness and its width (see FIG. 3b).
  • the spring characteristic is strongly progressive, which is at least partly due to the fact that part of the apex 4a on the crossbar 3 and part of the two lower legs 4d, 4e increasingly bears against the longitudinal member la during deflection, so that the for Shorten the effective sections of the leaf spring.
  • This progressivity can accordingly be influenced by changing the radii of curvature on the one hand for the apex and on the other hand for the two lower legs.
  • Figure 4 shows a similar embodiment of the slatted frame as Figures 3a and 3b, but the slatted frame in the case of Figure 4 consists of side members with a rectangular cross section and a hard rubber block 5, which is attached to the apex 4a of the leaf spring 4 at its junction with the crossbar 3 and as an elastic type impact serves to limit the spring travel.
  • Figure 5 shows an embodiment similar to Figure 3a .
  • C-shaped leaf spring elements 6 one of which is in the right part the figure is shown on the one hand in the loaded, on the other hand in the unloaded state.
  • the connection of these C-shaped leaf spring elements to the leaf spring 4 can be designed in a simple manner in such a way that the leaf spring elements can subsequently be inserted or removed by hand and without tools.
  • pins 6a to be riveted, which engage in corresponding holes provided in the leaf spring. 4
  • Other solutions for example in the form of breakthroughs that interact with corresponding notches, are also possible.
