Definitions

  • the invention relates to a bed frame with two frame side members and cross members connecting them to one another and a mattress support, in particular spring wooden strips arranged between the frame side members, in which at the foot end on the inner sides of the two frame side members a support rail is connected to a frame side member via two essentially rectified links of different lengths , which forms an open angle at the foot end between the horizontal and each itself, and an oppositely inclined locking lever is articulated with its upper end on the associated frame longitudinal member and is so displaceably mounted in a guide with a lateral locking lug at its lower end that the locking lug can be snapped into any one of several locking recesses and can be returned to the starting position beyond the end position.
  • the arrangement of the parts relative to one another in the known construction means that the latching lug of the latching lever must be brought into engagement with the latching recesses on the relevant handlebar and held by a spring.
  • springs can easily be the cause of malfunctions or fail after certain periods of use, making the entire adjusting device inoperable.
  • the object of the invention is to provide a bed frame of the type in which, while maintaining its main advantages, namely a relatively simple design of the overall construction and the independence of the type and longitudinal extension of the support rails on both sides of the bed frame, the stability of the adjustment and its functional reliability is further improved.
  • this object is achieved according to the invention; that the guide provided with the catch recesses is attached to the support rail extending in the longitudinal direction thereof, and that the latching nose, after passing through the catch recesses when the foot end is lifted, returns to the starting position via a run-up surface and a deflection switch while lowering the foot end again.
  • latching in question is assigned to the other parts of the adjusting device or the pivotable bed frame part in a different way.
  • the latching lever articulated on the pivotable bed frame part extends essentially in the same direction as the bed frame part to be pivoted, which in turn causes unfavorable lever and force transmissions resulting therefrom.
  • the deflector is advisable to form from a one-sided articulated, angular, rigid slider, firstly because this increases the stability of the horizontal sliding surface and secondly because the bearing of the deflector becomes particularly stable by contacting the other vertical angled arm on the guide housing .
  • the locking links assigned to the two longitudinal frame members can also be connected to one another by means of a cross strut, which ensures even locking on both sides of the foot end even when the foot end of the bed frame is raised on one side.
  • a cross strut Such locking levers connected by a cross strut are known in a bed frame according to DE-OS 23 15 337 or CH-FS 533 970.
  • a bed frame with the simplest design, generally designated 1, of two panel feet 2 which are fastened with longitudinal frames 3, preferably screwed together.
  • Cross frames 4 are fastened by screwing between the ends of the longitudinal frames 3.
  • the actual bed frame designated overall by 5, consists essentially of two frame side members 7 and cross members 6 connecting them to one another and spring strips 8 fastened to the frame side members 7 in the usual manner, with each frame side member 7 being assigned an angular support rail 9 at its foot end such that the Frame side member 7 rests in the lowered position on the horizontal leg of the support rail 9.
  • a pivotable head part is not formed, as shown in particular in Figure 1.
  • a locking lever 12 is articulated on the frame longitudinal member 7, at the lower end of which a locking nose 13 is arranged.
  • a guide 14 is also fastened, which has two latching recesses 15 and 16, each of which is preceded by a run-up surface 17 and 18, respectively.
  • an angular deflector 20 is articulated on a vertical wall 19 of the guide 14, the free end of which rests on a further contact surface 21 arranged at the head end of the guide 14.
  • a vertical boundary surface 22 on the head side and an upper horizontal boundary surface 23 are formed above the horizontal leg of the deflection switch 20, a vertical boundary surface 22 on the head side and an upper horizontal boundary surface 23 are formed.
  • the catch 13 of the catch lever 12 engages in the guide 14 from the inside and can pass through the positions and guideways indicated by dashed lines in FIG. 3.
  • the support rails 9 on both sides are connected to one another via a cross strut 24, as are the locking levers 12 on both sides by a further cross strut 25.
  • the dimensions of the handlebars 10 and 11 and the locking lever 12 and their articulation points on the support rail 9 and frame side member 7 are selected such that, on the one hand, when the foot end is raised, the articulation points of the handlebars 10 and 11 on the frame side member 7 lie on an alternating inclined straight line and, on the other hand, the locking lug 13 of the locking lever 12 snaps into the corresponding locking recesses 16 of the guide 14.
  • the latches 13 on both sides pass from the starting position 1 shown in dashed lines in FIG. 3 via the ramp 17 into the latch recess 15 (position 11 of the latch 13) and with further lifting via the ramp 18 into the latch recess 16 (position 111 of the locking lug 13), such that the bed frame 5 assumes two possible inclination positions.
  • the foot end of the same is raised further, the latching lugs 13 on both sides passing the deflector 20 via the run-up surface 21 (position IV of the latching lug 13) and then running back over the horizontal leg of the angular deflector 20 when the foot end is lowered (position V of the locking lug 13) and finally fall back into position 1.
