Definitions

  • the invention relates to a pivotable arrangement for adjusting and supporting frame upper parts compared to a fixed frame lower part or the like.
  • a pivotable arrangement for adjusting and supporting frame upper parts compared to a fixed frame lower part or the like.
  • With two support points per frame upper part each of which is provided with a locking toothing, torsionally rigid on the lower frame part C or toothed rail or the like.
  • Starting position is in operative connection.
  • This center handle is hardly ever used when a bed is standing on a wall, for example, so that the handle is difficult or impossible to reach, with the result that the locking teeth of both support plates rest unevenly.
  • the supports of the support plates are Y-shaped and are attached at their ends to the cross member of the pivotable frame top part with torsion-resistant fastening pieces (plates).
  • Each bracket is connected to a toothed rail via a swivel bearing, which is pivotably but torsionally rigid on the fixed cross member of the lower frame part.
  • Support levers are articulated to the swiveling areas of both support plates, the other ends of which are articulated to the fixed cross member of the lower frame part.
  • the present invention is based on the object of reducing the susceptibility to twisting of frame upper parts compared to their frame lower parts, especially in the case of light frame constructions.
  • the respective raised frame side takes the opposite side of the upper frame part with it in a torsionally rigid manner, so that the locking teeth on both sides of the upper frame parts are adjusted simultaneously and equally.
  • the so-called Y-actuators ensure the lateral stability of the upper frame part, the intermediate connection ensures the torsional rigidity of the arrangement. Even in the case of lightly constructed upper parts of the frame, the locking teeth on the side that is not raised come into action at the same time as the locking teeth on the raised side.
  • the end faces of at least one torsionally rigid cross member are pivotally attached to the longitudinal bars of the lower frame part and the articulated ends of the C or toothed rails or the support of the support plate are firmly connected to the pivotable, torsionally rigid cross member.
  • Each articulated end is attached to the torsionally stiff, pivotable cross bar either with two screws or rivets or with only one screw or rivet at a time. Fastening with just one screw or rivet is sufficient if the articulation end to be fastened is secured against pivoting by a lowering or an indentation in the pivotable cross member. Without such a lowering or indentation, only one screw or rivet would act as the axis of rotation for the respective articulation end.
  • a bearing screw screwed into the end face of the cross member is used with a threaded part and a bearing part which is fastened in the pivotable, torsionally rigid cross member of the lower frame part.
  • Such pivot connections between the longitudinal spars of the lower frame part and the pivotable cross member are characterized by the simplicity of their individual parts and their easy assembly.
  • Fig. 1 shows a schematic, perspective partial view of a lower frame part 4, to which a frame upper part 1 is pivotally connected in a manner not shown.
  • a cross member 2 is shown from the upper frame part 1, which is firmly connected to the side members 3.
  • the lower frame part 4 has longitudinal bars 12 which are connected to one another by fixed cross bars 5.
  • two support plates 31 are arranged, by means of which a snap-in in any position when raising the upper frame part 1 relative to the lower frame part 4 and a restless return of the upper frame part 1 to its rest position can take place .
  • the support plates 31 shown in FIG. 1 are only shown, for example, although they are preferred exemplary embodiments of support plates. In connection with the invention, other support actuators can also be used which fulfill the same task as the support actuators 31 shown.
  • the swivel joints 36 which have articulated fastening plates 38, are connected to the supports 40, each of which has a latching joint 46, to which a latching strut 47 with teeth 48 is connected in an articulated manner.
  • the toothing 48 interacts with the locking toothing 35 of the C or toothed rail 32 in a manner known per se, which is not explained in detail here.
  • the locking strut 47 and its teeth 48 and the locking teeth 35 are connected to an arrangement for restoring the arrangement to the starting position without rest.
  • each carrier consists of two side struts 41 and 43, which diverge from the latching joint 46 from a Y shape.
  • Each side strut 41, 43 has an articulation end 42, 44.
  • the two articulation ends of a bracket 40 are fastened to the fixed cross member 2 of the upper frame part 1 by means of a fastening plate 45.
  • Both support plates 31 of the first exemplary embodiment are connected to one another by an intermediate connection 50.
  • an intermediate connection consists of a side strut 51 with articulated end 52 and a side strut 53 with articulated end 54.
  • the intermediate connection 50 consists of a flat strut made of steel band, which is shaped into an intermediate connection 55.
  • the side struts 51 and 53 converge obliquely (V-shaped) to the intermediate connection 55.
  • This intermediate connection 55 is articulated by means of a fastening piece 56 on the fixed cross member 5.
  • the fastening piece has articulation angles 57, between which the intermediate connection 55 is pivotably mounted.
  • the so-called Y-actuators take over the lateral stability of the upper frame part 1 compared to the lower frame part 4.
  • the intermediate connection 50 takes on additional lateral stability over the entire frame complex with a limited torsional rigidity with a stable frame design.
  • the articulation ends 52 and 54 of the side struts 51 and 52 of the intermediate connection 50 can be connected to the swivel joints 36, for example, by means of articulated fastening plates 38. These articulation ends 52 and 54 can also be connected to the articulation ends of the supports 40 or to the articulation ends 33 of the C or toothed rails 32.
  • FIGS. 2 and 3 show details of the first embodiment of the invention on an enlarged scale. It can clearly be seen that the side struts 51 and 53 of the intermediate connection 50 consist of flat iron.
  • the essentially V-shaped intermediate connection 50 is formed into a U-shaped intermediate connection 55 which is mounted and guided between the articulation angles 57 of the fastening piece 46 known per se.
  • the articulation ends 52 and 54 of the side struts 51 and 53 are deformed in such a way that they can be connected, for example according to FIGS. 2 and 3, to the C or toothed rail 32 by means of a rivet which is not specified in detail.
  • the hinge pins of the fastening pieces 39 and of the fastening piece 56 lie on a common pivot axis, not shown in detail.
  • Fig. 4 shows a schematic perspective partial view of the second embodiment of the invention.
  • the previously described support plates 31 are used, the Y-plates of which are articulated in the manner described on the fixed cross member 2 of the upper frame part.
  • the lower frame part 4 is connected to a pivotable and non-rotatable cross member 6.
  • this non-rotatable, pivotable cross member has a square, in particular rectangular, cross section 7.
  • the torsionally stiff and pivotable cross member 6 can also have a square, round or differently profiled cross-section, if this ensures adequate security against rotation.
  • the articulation ends of the C or toothed rail 32 of the support plate 31 are firmly connected to the non-rotatable pivotable cross bar 6. If these articulation ends of the C or toothed rails 32 are secured against rotation on the flat surface, for example a pivotable cross bar 6 with a rectangular cross section, two screws or rivets are required in each case in order to prevent the C or toothed rails 32 from being in find their pivot axis by means of only one screw or rivet Steel can also be welded.
  • depressions 27 are arranged in the spar 6, into which the articulation ends of the C or toothed rails 32 fit tightly. These depressions 27 prevent the C or toothed rails from rotating about their attachment to the spar. For this reason, only one screw or one rivet is required in the type of fastening shown in FIG. 4.
  • Fig. 4 shows a screw head 18 of a bearing screw 16 to be described in detail below, by means of which the pivotable cross member 6 is articulated to a longitudinal spar 12.
  • the bearing screw 16 belonging to the screw head 18 is in each case screwed into the end face 8 of the pivotable non-rotatable bar 6.
  • These end faces 8 each face the inner walls 13 of the longitudinal spars 2.
  • FIGS. 5 to 7 Details of various exemplary embodiments for the pivotable fastening of the non-rotatable and pivotable cross bars 6, 9 to the longitudinal bars 12 are shown in FIGS. 5 to 7.
  • Fig. 5 shows schematically the connection of a cross bar 6 with a rectangular cross section to the longitudinal spar 12.
  • the threaded part 12 of a bearing screw 16 is screwed, which has a bearing part 17 between the threaded part 20 and the screw head 18.
  • This bearing part 17 is pivotally mounted in the longitudinal spar 12.
  • a washer 19 is provided between the screw head 8 and the corresponding area of the longitudinal spar 12.
  • the bearing 15 has a spacer 21.
  • Fig. 5 illustrates that as a result of this depression 27, a rotation of the pivot end 34 of the C or toothed rail 32 relative to the pivotable cross member 6 is not possible and that only one screw or rivet is required to secure it.
  • FIG. 6 shows a pivotable cross member 9 with a tubular cross section 10.
  • An indentation 28 is provided in the tube wall for fastening the articulation end 34 of the C or toothed rail 32, which indentation is shown only schematically in FIG. 6. This indentation 28 also prevents the articulation end 34 from rotating relative to the pivotable cross member 9.
  • the threaded part 20 of the bearing screw 16 is screwed, which - as already described - is pivotally mounted in the cross member 12 by means of its bearing part 17.
  • Fig. 7 shows a modified pivot bearing 15 of a pivotable cross member 9 with a tubular cross-section 10.
  • an incision 29 is provided, which in the assembled state is opposite a depression 26 in the threaded / bearing plug 22.
  • the incision 29 is dimensioned such that the articulation end 34 of the C or toothed rail 32 fits tightly into it and needs to be fastened on the depression 26 by means of only one screw or rivet.
  • the threaded / bearing plug 22 shown in FIG. 7 also has an edge or collar 23 which prevents the threaded / bearing plug 22 from being pressed too much or too deeply into the end face 11 of the pivotable crossbar 9.
  • the cross bar 12 is indicated in FIG. 7 with dash-dotted lines.
