Definitions

  • the invention relates to a device for adjusting a pivotable bed frame part with a locking recess having a lower fitting part, a locking lever cooperating with it and an upper fitting part and a return of the locking lever from an end position to the initial position allowing the slide on the lower fitting part, the lower fitting part and the upper part Fitting part are each U-shaped and the locking recesses in the U-legs of the lower fitting part are recessed and the slide is guided between the U-legs of the lower fitting part.
  • the lower fitting part having the latching recesses is essentially U-shaped, with stiffening of the lower fitting part in the two U-legs and possibly in the connecting base of both U-legs each formed a longitudinal bead is.
  • the longitudinal beads in the U-legs simultaneously serve as guides for the return of the locking lever allowing the slide, whose cross-section is adapted to the cross-section of the U-profile of the lower fitting part that the slide largely rests on all sides on the lower fitting part.
  • a disadvantage of this known device is the relatively complex production.
  • the longitudinal beads must be molded into the lower fitting part and, moreover, the slide must be adapted exactly to the cross section of the lower fitting part, in particular in the bead area, in order to ensure exact guidance.
  • a further disadvantage of this known device is that when the slide is returned from the end position, the upper fitting part with associated bed frame part, if it is not securely held by the user, can easily fall down, which leads to a risk of injury.
  • the object of the invention is to provide a solution with which can be simplified in a generic device while improving the functional reliability.
  • the manufacture of such a device is significantly simplified since the lower fitting part having the recesses only has to be cranked inwards at the free ends of the U-legs, but otherwise no further forming processes are required.
  • the slide does not have to be adapted exactly to the profile shape of the lower fitting part, it is only necessary that the width of the slide is greater than the distance between the inward cranks of the lower fitting part.
  • the slide with respect to the axis of symmetry of the U-profile of the lower fitting part consists of two mirror-symmetrical halves which are connected to one another in the front region at the connecting webs.
  • the slide which is preferably made of plastic, then requires only a small amount of material, which is a corresponding advantage for reasons of cost and weight.
  • the slide only rests on the lower fitting part in the two corner areas of the U-profile and in each case in the area below the inward bends.
  • This configuration is particularly material-saving, for example the slide in the area led into the lower fitting part can be designed in cross-section approximately U-shaped with outwardly protruding corner areas.
  • a device for adjusting a pivotable bed frame part is generally designated 1 in the drawing.
  • the device 1 consists essentially of an upper, U-shaped fitting part 2, a lower, reversely U-shaped fitting part 3, a detent lever 4 cooperating therewith and a slide 5.
  • the U-shaped upper fitting part 2 receives the detent lever 4 by means of a rivet bolt 8 in such a way that the detent lever 4 can be pivoted relative to the upper fitting part 2.
  • a longitudinal slot 18 which serves as a guide for the detent lever 4 in the middle of the U-profile.
  • the likewise U-shaped lower fitting part 3 is cranked inwards in the region of the free ends of its U-legs 3a, these inward crankings are designated by 20.
  • the inward cranks 20 serve as stiffening and at the same time as an upper guide limitation for the slide 5.
  • detents 13 are incorporated for the adjustment of the detent lever 4.
  • an indentation 15 is additionally provided in the lower fitting part 3 in order to prevent the rivet bolt 8 from hitting open.
  • the upper and lower fitting parts 2, 3 are pivotally connected to one another by a further rivet bolt 10, the pivoting being correspondingly limited by the detent lever 4.
  • the slider 5 is preferably made of plastic and serves to raise the detent lever 4 when the head or foot part of the associated bed frame attached to the upper fitting part 2 is lowered. In the lowered state, the locking pin 9 of the locking lever 4 rests on a return surface 14 of the functional opening 17 in the webs of the slide 5.
  • the slide has a cross-section symmetrical to the axis of symmetry of the U-profile of the lower fitting part 3 (FIG. 3) and consists of two halves which are connected to one another in the front area by a connecting web 19.
  • the width of the slider 5 corresponds approximately to that of the legs 3a of the lower fitting part 3, while in the rear area 16 of the slider the slider is made in excess width, so that a displacement of the slider 5 is impeded by friction to avoid a slight adjustment from the end to the start position or to prevent the upper fitting part 2 from falling down.
  • the detent pin 9 of the detent lever 4 leaves the return surface 14 of the slide 5 and can engage in the corresponding detents 13 of the lower fitting part. Pulled over the last catch 21, when the upper fitting part 2 is left behind, the catch bolt 9 runs onto the return surface 14 of the slide 5 and is returned to the starting position without touching the catches 13. The adjustment process can then be carried out again.
  • the invention is not limited to the embodiment shown in the drawing. Further refinements of the invention are possible without leaving the basic idea.
  • the locking recesses 13 can be arranged differently in the lower fitting part, for example the indentations can simply be designed as right-angled bends of the U-legs, in which the locking recesses are then also formed and the like. More.
