Definitions

  • the invention relates to a fitting for attaching a slat bearing cap to a longitudinal spar of a slatted frame.
  • fittings are also already known in a two-part embodiment, a fitting part carrying the slat bearing cap being displaceable against the force of a spring by way of a guide on a fixed fitting part connected to the longitudinal spar, in order in this way to adjust the total spring travel via the elastic deformation of the Rubber manufactured bearing cap to increase available travel.
  • a corresponding fitting is e.g. described in DE-OS 35 40 040.
  • the present invention is intended to develop a fitting in accordance with the preamble of claim 1 in such a way that an even greater spring travel is achieved with compact overall dimensions of the fitting.
  • the fitting according to the invention can be implemented using flat plastic or sheet metal parts, so it is very short in the longitudinal direction of the slats of the slatted frame.
  • the fitting is mechanically simple and robust and works even after long use without the risk of jamming.
  • a fitting as specified in claim 4, can be attached at selected points of a standard longitudinal spar of a slatted frame directly instead of a non-resilient standard fitting, over which a slatted bearing cap is attached directly to the longitudinal spar in a simpler slatted frame.
  • the angle levers can move with their free, the first lever arms having the support elements over the pivot bearings of the other angle lever. This gives you a large working stroke with a compact overall dimension of the fitting. You can also place the pivot bearings in places that are behind an angle lever when the fitting is not under load. Such a choice of the pivot bearing is advantageous with regard to the setting of the contribution made by the elastically deformable slat bearing cap to the total spring force of the slat bearing.
  • the development of the invention according to claim 8 ensures the above-mentioned coupling of motion with low slip and thus low noise.
  • the spherical projection also promotes different tilting of the angle levers when the two support elements are loaded unevenly.
  • the user can adjust the hardness of the slatted storage himself according to his wishes.
  • a load-bearing stop device is obtained without any noteworthy additional effort, which specifies the fully sprung-in, lowest position of the angle lever.
  • a fitting according to claim 16 is encapsulated upwards and laterally, so that there is no risk of getting caught between the angle levers.
  • a section from the longitudinal spar of a slatted frame is shown at 10.
  • Two angle levers 16, 18 are mounted on the inner surface of the longitudinal spar 10 by means of screws 12, 14.
  • the screws 12, 14 are countersunk screws and clamp the angle levers 16, 18 in the sliding play between them and retaining pins 20 which are corrugated on the outside.
  • the holding pins 20 have a diameter and an outer contour like the usual holding pins of rigid standard bearing cap support fittings. They are pressed into blind bores 22 in the longitudinal spar surface.
  • the angle lever 16 has, in the drawing, a first lever arm 24 with an offset 26, which extends in the horizontal direction.
  • a second lever arm 28, which runs downwards in the drawing, has a short length compared to the first lever arm 24 and is mounted on the screw 12.
  • a spherical projection 30 is provided on the lower edge of the first lever arm 24, in the area lying on the right of the crank 26.
  • the second angle lever 18 has a first lever arm 32 of great length, which extends essentially horizontally in parallel under the first lever arm 24 of the angle lever 16.
  • the lever arm 32 also has a crank 34, which is offset to the projection 30 to the right in the drawing (thus also to the crank 26) and the like
  • the axes of the screws 12, 14 and the axes of the support elements 40, 42 form a flat rectangle if no external forces act on the fitting.
  • a bearing cap 44 In the finished slatted frame, a bearing cap 44, indicated by a broken line in the drawing, with corresponding cap bores is pushed onto the supporting pins 40, 42.
  • the bearing cap 44 is a one-piece molded part made of synthetic or natural rubber and has two receptacles 46, 48 for one slat end each.
  • a bearing sleeve 50 is molded onto the lower end of the lever arm 28.
  • An actuating bushing, designated 52 in total, runs in this. This has a corrugated adjusting wheel 54 and is divided in its right section by slots 56 into individual tongues, so that a bead 58 lying at the socket end can be pushed through the bearing sleeve 50 while elastically compressing the socket end.
  • a threaded bolt 60 runs in the adjusting bushing 52 and is provided on the right-hand end with a receiving bore 62 for one end of a helical spring 64. Its second end engages a retaining bolt 66, which on the second lever arm 36 is formed and is provided with means (not shown in the drawing) for fixing this spring end, for example an annular groove.
  • a stop pin 68 inserted into the inner surface of the longitudinal bar 10 limits the rotational movement of the first angle lever counterclockwise.
  • the bell crank 18 is biased in a clockwise direction and then comes under this biasing force into contact with the projection 30, which thus limits the rotational movement of the bell crank 18 in a clockwise direction. In this way, the rest position of the two angle levers 16, 18 assumed in the absence of external forces, which is shown in the drawing.
  • the individual turns of the coil spring 64 are still spaced apart from one another in the rest position of the fitting, so that the coil spring 64 never comes on block.
  • the angle lever 16 rotates clockwise, the angle lever 18 rotates counterclockwise, and the coil spring 64 is additionally tensioned accordingly. Because of the cranks 26 and 34, the lever arm 24 can move over the screw 14 and the adjacent part of the angle lever 18, while the lever arm 32 can run over the lever arm 28 and the screw 12. If the slat connected to the receptacle 46 is loaded more heavily than the slat connected to the receptacle 48, the angle lever 18 can pivot further down than the angle lever 16, so that an overall inclined position of the lying surface is obtained. Conversely, if the slat sitting in the receptacle 48 is loaded more than the slat lying in the receptacle 46, the angle lever 16 presses the protrusion 30
  • Angle lever 16 with down and both slats are lowered to the same extent. A negative position of the lying surface is therefore excluded. Such behavior is particularly desirable at the transition area to a head part of the slatted frame that is adjustable in its inclination.
  • the distance between the support pins 40, 42 changes, and the lower section of the bearing cap 44 is correspondingly elastically deformed.
  • the rubber material of the bearing cap thus provides an additional restoring force that is added to that of the coil spring 64.
  • the distance between the two support pins 40, 42 initially increases until they have reached the connecting line of the screws 12, 14. If the fitting was deflected even further, the distance between the support pins 40, 42 would then decrease again.
  • the material of the bearing cap 44 which lies between the cap bores which receive the support pins 40, 42, is thereby subjected to tension.
  • angle lever pivot axes and support Pin axes in the rest position of the lining are preferred because of the increasing amount of the restoring force towards the end of the spring travel.
  • crankings 26, 34 of the angle levers 16, 18 were in spaced vertical planes lying perpendicular to the plane of the drawing such that the upper angle lever 16 was not freely pivotable downwards, but rather with its projection 30 on the upper edge of the lever arm 32 of the lower angle lever 18 abutted, so that pivoting downward of the upper angle lever 16 inevitably led to pivoting downwards of the lower angle lever 18. If you do not want such a take-along, the crankings 26, 34 can be moved to the right or left, so that the two lever arms 24, 32 no longer touch when the angle lever 16 is pivoted.
  • the fitting according to FIG. 2 shows this type of arrangement of the cranks 26, 34.
  • the offset 34 is displaced such that it starts from the upper edge of the lever arm 32 in the vicinity of the trunnion 42 and then falls obliquely downward in FIG. 2 at approximately 20 °.
  • the angle lever axes of rotation are laid so that they are aligned with the axes of the support pins 40, 42 in the position of the angle lever 16, 18 assumed in the unloaded state of the fitting. In this way, the upper angle lever 16 in the exemplary embodiment according to FIG. 2 can be pivoted downward from the rest position by an angle of approximately 20 ° without the angle lever 18 being moved.
  • the angle levers 16 and 18 are mounted on a base plate 70 which has an edge wall 72 which surrounds the angle lever arrangement at the top and on the sides and is guided essentially into the plane of the end faces of the lever arms 24, 32.
  • Hollow mounting pins 74 are formed on the back of the base plate 70 and are provided on the outside with a corrugation that is not shown in the drawing.
  • the mounting pins 74 are press-fitted into blind bores 22 which are provided in the longitudinal spar 10 of the slatted frame provided with the fitting.
  • the first lever arms 24, 32 each have the shape of a U with short legs, for which purpose they each have a mirror-image curved end section 76 in addition to the curved end section 38 on the trunnion side.
  • the trunnion axis of one angle lever thus lies above the trunnion axis of the other angle lever when the fitting assumes its rest position shown in FIG. 2.
  • the angle levers 16, 18 carry in their second lever arm 28 or 36 facing the base plate 70 a hollow bearing journal 78 or 80 which fits into the associated assembly journal 74 in sliding play.
  • the end of the journal 78, 80 is each provided with a slot 84 so that a locking bead 86 provided on the journal end can be moved through the assembly journal 74 by elastically compressing the journal end.
  • the distance of the locking bead 86 from the rear end face of the lever arm 32 or 36 is such that there is an axial sliding play between the angle levers and the base plate.
  • a second stop pin 88 is provided on the base plate 70, which cooperates with a stop wing 90 that starts from the lever arm 24.
  • Cylindrical rubber buffers 92 are placed on the stop pins 68, 88, which dampen the movement of the two angle levers 16, 18 into the upper rest position and prevent rattling noises.
  • stop ribs 94, 96 are formed in the lower right or left corner, which cooperate with the lower outer edges of the lever arms 28, 36 and specify the fully sprung position of the angle levers 16, 18.
  • the base plate 70 is a one-piece plastic injection-molded part, as are the angle levers 16, 18.
  • the latter are hollow injection-molded parts which are open to the rear and provided with ribs 100 where necessary, to which the spring seats 62, 66 are only schematic for those in FIG indicated helical spring 64 are formed.
  • the fitting according to FIGS. 2 to 7 thus consists of a total of only six different parts which can be assembled easily and without tools: the base plate 70, the rubber buffers 94 to be placed on the stop pins 68, 90, the angle levers 16, 18 and the coil spring 64 the fitting factory assembled fitting can also be very easily mounted on the longitudinal beam 10 by pressing its mounting pin 74 into the blind holes 22 prepared there.
