Definitions

  • the invention relates to a device for gradually adjusting the distance of a first element held on one chair part from a second element held on another chair part.
  • the invention is based on the object of improving an adjusting device of the generic type in such a way that increased safety and still a small space requirement can be achieved with little design effort.
  • a second latching slide is provided with latching recesses arranged one above the other, that both latching slides are slidably mounted on the first element transversely to the adjustment direction, that the latching recesses in each latching slide are on the other latching slide facing side of each locking slide and are open to this side, the locking recesses of the two locking slides opposite each other in pairs, that between the two locking slides perpendicular to the direction of adjustment and perpendicular to the direction of displacement of the locking slider, connected to the second element is arranged and that the wedge drive is provided with a slide which is displaceable parallel to the direction of adjustment on the first element, the locking recesses of the locking slide arranged in pairs locking the bolt in the locking position reach around from both sides, while in the open position between the locking slides it can be moved parallel to the adjustment direction.
  • the adjustment device consists of a few parts, namely a first element connected to a chair part, two latching slides, a slider connecting them, an elastic force accumulator and a bolt passing between the latching slides, which is connected to the second element.
  • the structure is therefore extremely simple, although the advantageous interaction of these few parts enables a safe and simple grid adjustment.
  • For the adjustment it is sufficient to move the slide, whereby the two locking slides are moved from the locking to the open position. In this position the bolt can be moved between the two locking slides, so the distance between the two elements can be adjusted.
  • the locking slides are moved back into the locking position under the action of the elastic force accumulator, the locking recesses open on one side engaging around the bolt in the desired position from both sides and thus fixing the distance between the two elements.
  • the slide of the wedge drive carries two drivers arranged at a distance in the adjustment direction, the inclined guideways of which rest on the two locking slides; the guideways are preferably formed by the long sides of elongated holes arranged in locking slides through which the drivers pass.
  • the drivers preferably penetrate elongated holes in the first element that run parallel to the adjustment direction, so that guiding the slide on the first element is thereby ensured at the same time.
  • the elastic energy accumulator is a compression spring which is supported on the one hand on the slide and on the other hand on the first element. This compression spring always shifts the slide into the position corresponding to the locking position, whereby by guiding the slide drivers on the guideways of the two locking slides, they are pushed indirectly into the locking position.
  • slots extending perpendicular to the direction of adjustment can be provided therein, through which pins fixed on the first element pass, which preferably also pass through slots in the slide extending parallel to the direction of adjustment. These pins also contribute to guiding the slide on the first element.
  • the first element has the shape of an elongated plate with an elongated elongated hole
  • the two latching elements are also designed as elongated plates, which lie flat on opposite sides of the first element
  • the locking position projections arranged between the latching recesses partially cover the elongated hole in the first element
  • the slide is constructed in a U-shape with two arms formed by elongated plates which lie flat against the latching slides from the outside, which each have an elongated hole aligned with the elongated hole in the first element.
  • This configuration enables a particularly compact structure of the device and also allows a very economical production of the individual parts of the device.
  • the locking slides have elongated holes, one long side of which carries the recesses which are open on one side.
  • the locking slides are preferably constructed identically and built into the device in mirror image.
  • the production of the parts is particularly advantageous if the first element and the locking slides are flat stamped parts.
  • the slide can advantageously also be constructed from stamped parts which form its two arms.
  • the arms are cranked at one end and joined together along the cranked ends.
  • a centering mandrel projecting into the interior can advantageously be used for a compression spring supported on the first element.
  • the first element on its side facing the web, can carry lateral tabs which fix the compression spring supported on the first element transversely to the adjustment direction.
  • the compression spring is fixed in the direction perpendicular to it by the arms of the slide.
  • the slide carries an actuating element.
  • the projections arranged between the latching recesses have at their end a region running perpendicular to the adjustment direction and that the latching slides in the locking position are at such a distance from one another that the opening formed by the two latching recesses extends perpendicular to the adjustment direction Areas is limited.
  • the recesses can have a semicircular cross section, with rectilinear regions extending perpendicular to the adjustment direction adjoining the semicircle to the edge of the locking slide.
  • the assembly consisting of the first element, locking slide and slide is located inside a pipe section and is fixed in this by a fixed connection of the first element to the pipe section, when in the pipe section opposing longitudinal slots for those passing between the locking slides Bolts are provided and if the pipe section is telescopically displaceable in the second element, which is also made of pipe.
  • a pin which extends through mutually opposite bores in the tube piece and through a bore in the first element can be provided for fastening the first element. It is advantageous if the pipe section on the side facing away from the second element is open, so that the slide can be actuated by the open end.
  • a chair back can be attached directly or indirectly to the first element, while the second element is attached directly or indirectly to a chair.
  • the device then serves to adjust the height of the chair back relative to the seat.
  • FIGS. 2 to 5 A preferred embodiment of the adjusting device according to the invention is described below with reference to FIGS. 2 to 5.
  • This comprises an elongated, plate-shaped first element 1, two likewise elongated, plate-shaped locking slides 2 and 3, which lie flat on opposite sides of the first element 1, and a U-shaped slider 4 with likewise elongated, plate-shaped arms 5 and 6, which lie flat with their inside on the outside of the two locking slides 2 and 3 (Fig. 4).
  • the design of the arms of the U-shaped slide, the locking slide and the first element results from FIGS. 6, 7 and 8 respectively.
  • the first element 1 has an elongated elongated hole 7 in its central region, on both sides of the same each have a bore 8 or 9 and at an even greater distance from the elongated hole 7 on both sides each also a longitudinally extending elongated hole 10 or 11, the elongated holes and bores being arranged symmetrically to the center line of the first element.
  • a bore 12 is also arranged on the center line of the first element.
  • the first element is provided with two upwardly projecting tabs 13 and 14, the distance from which corresponds to the outside diameter of a compression spring described in more detail below.
  • the locking slides 2 and 3 also have an elongated hole 15 which has on one longitudinal edge towards the elongated hole 15 open recesses 16 which are arranged at a distance from one another, while the opposite side of the elongated hole passes straight through.
  • the locking recesses have a substantially semicircular cross section, the center of the locking recesses being a small distance from the elongated hole side.
  • a region 17 running perpendicular to the elongated hole side adjoins the semicircular contour of the recesses 16. There are therefore projections 18 between adjacent latching recesses, the contour of which in the area near the slot extends perpendicular to the expansion of the slot.
  • the length of the elongated hole 15 corresponds to the length of the elongated hole 7 in the first element 1.
  • elongated holes 19 and 20 running transversely to the longitudinal extent of the elongated hole 15, the spacing from one another being the mutual spacing. corresponds to the holes 8 and 9 in the first element 1.
  • parallel, oblique slots 21 and 22 are provided in the two end regions of the locking slide, the meaning of which will be explained in more detail.
  • the two locking slides 2 and 3 are constructed identically, both the first element 1 and the locking slides 2 and 3 are flat stamped parts.
  • the arms 5 and 6 of the slide 4 are stamped parts which are cranked at one end; in this area the laterally offset end areas 23 and 24 lie flat against one another and are welded together, for example. These end areas form the web of the U-shaped slide.
  • the end regions 23 and 24 of the arms are punched out in the middle, so that an opening is created in the web of the slide, through which a centering mandrel 25 is inserted.
  • the centering mandrel is welded to the slide such that a conical end 26 passes through the web into the space between the two arms 5 and 6, while the opposite end 27 of the centering mandrel 25 extends beyond the end regions 23 and 24 of the slide 4 (Fig. 4).
  • Both arms 5 and 6 of the slide have an elongated hole 28 running along their center line, which is formed wider in its central region 29 than in its two end parts 30 and 31.
  • the central region 29 is somewhat longer than the elongated holes 7 and 15 in first element or in the locking slides.
  • the individual parts described in detail above are combined to form a structural unit in the manner shown in FIGS. 2 to 5.
  • the two locking slides of the same design are arranged on the opposite side of the first element, the package made up of the first element and the two locking slides is inserted between the arms of the slide, the spacing of which corresponds exactly to the package thickness.
  • pins 34 and 35 which through the end parts 30 and 31 of the elongated hole 28 of the two arms, through the transverse elongated holes 19 and 20 of the two locking slides and through the bores 8 and 9 of the first Element.
  • These pins can be rivets, for example.
  • a compression spring 36 is inserted, which surrounds the conical end 26 of the centering mandrel 25 on one side and abuts the end face of the first element on the other side. Lateral displacement of the compression spring 36 is avoided on the one hand by the tabs 13 and 14 and on the other hand by the inside of the arms 5 and 6 (cf. FIGS. 2 and 4).
  • the oblique slots 21 and 22 of the locking slide and the slots 10 and 11 of the first element driving pins 37 and 38 are also inserted, which could also be formed by rivets.
  • These driver pins 37 and 38 which are fixed in the bores 32 and 33 of the slide, can be displaced when the slide is moved along the elongated holes 10 and 11 of the first element. In addition, they move along the oblique slots 21 and 22 of the locking slide, which are inevitably displaced perpendicular to their longitudinal extent.
  • the elongated holes 21 and 22 are arranged in the latching slides in such a way that the latching slides are in a so-called locking position when the slider is not displaced, i.e.
  • a holding pin 42 is inserted through two mutually opposite bores 40 and 41 in the pipe section 39 and through the bore 12 in the first element, which fixes the structural unit in the axial section in the pipe section.
  • the pipe section 39 has two mutually opposite longitudinal slots 43 and 44 which are aligned with the longitudinal slot 7 in the first element and have at least the same length.
  • the pipe section 39 slides telescopically in a pipe 45 which carries a bolt 46 held in the two walls and diametrically penetrating the pipe. This protrudes through the longitudinal slots 43 and 44 in the pipe section 39, through the elongated holes 29 in the two arms of the slide, through the elongated holes 15 in the two locking slides and through the elongated hole 7 in the first element.
  • the tube 45 provided with the bolt 46 is also referred to below as the «second element», the distance of which from the «first element 1» can be adjusted by the device described above.
  • the pipe section 39 is open at its end 47 facing away from the pipe 45.
  • the slider 4 can be actuated through this opening.
  • he preferably carries an actuating button 48 pushed onto the projecting end 27 of the centering mandrel 25, which either. protrudes from the pipe section 39 or is arranged in this in such a way that it is arranged in the locking position with its actuating surface a little below the edge of the pipe section.
  • the latter arrangement has the advantage that the slide cannot be operated unintentionally.
  • the pipe section 39 can support the seat back of a chair, while the tube 45 is designed as a seat back support and is connected to the seat surface or the lower part of the chair.
  • the slide 4 is displaced under the influence of the compression spring 36 in such a way that the two locking slides are in the locking position in which two locking recesses of the two locking slides, which are located opposite one another in pairs, grip the bolt from both sides and thus its position relatively fix to the first element.
  • the slide 4 In order to change the mutual distance between the first and the second element, the slide 4 is displaced against the force of the compression spring 36. As a result, the two locking slides are pushed apart by the drive pins 37 and 38 forming a wedge drive and the oblique elongated holes 21 and 22 in the locking slides until the gap between them enables the bolt 46 to be freely moved along the elongated holes 7, 15 and 28. As soon as the desired position of the bolt 46 has been determined, the slide 4 is released, which, under the influence of the compression spring 36, reaches its starting position and in the process also moves the two locking slides towards one another again. Corresponding to the new position of the bolt 46, other locking recesses lying opposite one another in pairs now grip the bolt and fix it in the new position.
  • the bolt 46 will rest on these areas running perpendicular to the adjustment direction. He can therefore not exert a force pushing the two locking slides apart on them, so that these areas which run perpendicular to the direction of adjustment ensure that the distance between the two elements cannot be inadvertently brought about under load.
  • the manufacture of the device according to the invention is extremely simple, as is the assembly.
  • All essential parts can be produced as stamped parts, the slide being easily produced from two stamped parts and the centering mandrel by welding.
  • the unit obtained is then inserted into the pipe section and fixed by inserting the retaining pin 42.
  • the tube piece with the adjusting device arranged therein is then pushed into the outer tube 45 and the entire device is assembled by inserting the bolt 46, which can then be permanently connected to the outer tube 45, for example by riveting.
  • the device described has the advantage that it is completely tele inside the two There is room for scoping tubes, the device is not visible from the outside. This applies in particular when the bolt 46 is riveted to the tube 45, since this can be done flush with the outer surface of the tube.
  • the actuation is extremely easy, it is sufficient to move the slide by pressing the actuation button 48 and to release it after the adjustment.
  • the device also has the necessary security, since an unintentional adjustment of the distance between the two elements is not possible because of the contour of the openings surrounding the bolt 46 which is perpendicular to the adjustment direction.
