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 substantially identical bars of different lengths , which form an open angle to the foot end between the horizontal and each itself, as well as an oppositely inclined locking lever with its upper end articulated to the associated longitudinal member and with a lateral locking lug at its lower end in a guide so that the Locking lug can be snapped into any of several locking recesses and can be returned to the starting position beyond the end position.
  • the locking lever is supported directly on the handlebar in question, which causes relatively unfavorable lever ratios and, as a result, large forces in the parts and joints in question, particularly in the particularly frequently set lowest pivoting position of the foot end of the bed frame in question.
  • 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.
  • such springs can easily be the cause of malfunctions or fail after certain periods of use, making the entire adjustment device inoperable.
  • the object of the invention is to provide a bed frame of the type in question, rt in which while maintaining its main advantages, namely a relatively simple design of the overall construction and the independence of A and longitudinal extent of the two-sided support rails on the bed frame, the stability of the adjustment as well as their operational reliability is further improved .
  • this object is achieved according to the invention in that the guide provided with the catch recesses on the support rail extends in the longitudinal direction thereof is fastened and that the latching nose, after passing through the latching recesses when the foot end is lifted, returns in a known manner via a run-up surface and a deflection switch while lowering the foot end into the starting position.
  • 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-PS 533 970.
  • the simplest configuration designated overall by 1, consists of two panel feet 2 which are fastened, preferably screwed, with longitudinal frames 3.
  • Cross frames 4 are fastened by screwing between the ends of the longitudinal frames 3.
  • the actual bed frame designated overall by 5, essentially consists of two frame side members 7 and cross members 6 connecting them to one another and spring strips 8 fastened to the side frame members 7 in the usual manner, each side member 7 at its foot end an angular support rail 9 is assigned 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 (not described in more detail) is also formed, as shown in particular in FIG. 1.
  • a locking lever 12 is articulated on the frame longitudinal member 7, at the lower end of which a locking lug 13 is arranged.
  • a guide 14 is also fastened, which has two locking 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.
  • Above the horizontal leg of the deflection switch 20 is a vertical boundary surface 22 on the head side and an upper horizontal regulator tion surface 23 formed.
  • the detent 13 of the detent lever 12 engages in the guide 14 from the inside and can pass through the positions and guideways indicated by the 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.
