Definitions

  • the innovation relates to an extendable and tiltable footrest for seating and reclining furniture, which can be moved and pushed out in different angular positions relative to the seat.
  • the cover located on the front of the armchair below the seat is usually folded down by means of a visible, designer disadvantageous and prone to scissors-like or lever-like mechanism for the footrest so that the padded front visible side serves as a footrest.
  • This in turn has the disadvantages that, for design reasons, this screen can not be padded strong enough and in particular cannot be upholstered to the body; in addition, it gets dirty very easily by placing the shoes on.
  • the invention was therefore based on the object of providing a footrest, the components of which work without problems and without interference and which can be asynchronously adjusted to any function according to the medical ergonomic requirements and which can also be appropriately padded to suit the body and with regard to possible soiling without the design thereby is affected.
  • the actual foot support surface on the swivel part can be narrower than the width of the axis about which ej swivels and than the width of the extension components; the panel opposite the foot support surface on the swivel component can be just as wide or wider than the extension component.
  • this screen can serve as a front chair screen.
  • the swivel part can also be slidably and pivotally mounted on the axis by means of an elongated hole guide, so that in the initial position in an end position of the elongated hole guide it is mainly stored vertically and both inclined and in use is displaceable in length relative to the push-out component and the seat.
  • the seat frame 2 is mounted between the laterally attached base frame 1 so that the frame menrohre 2 can be used as counterbearing tubes for the rollers 6 attached to the push-out components 8.
  • the rollers 5 carry. The roles are in their run Expediently deepened crescent-like, so that they can also perform leadership functions for pipes in addition to the rolling function. Between the rollers 5 run pipes or Kun tstoffstäbe or wooden rods are affixed to the rear end thereof lugs 7, 8 which in turn carry rollers 6.
  • the tubes 8 are supported on the seat frame 2 by means of the rollers 6.
  • the front ends of the tubes 8 are connected by an axis 9.
  • On this axis 9 of the pivot member is pivotally mounted by means of a storage 1o. 13
  • the swing member 13 is composed of the diaphragm 11 and the footrest 12 and storage 1 0th
  • the push-out component 8 has straps 7 at its rear ends which strike the rollers 5 when the footrest is fully extended and prevent them from falling out towards the front.
  • the function of the plastic sliding bushes 15 and 16 to be described later is similar.
  • the swivel part therefore has no swivel or tilt coupling with another component in such a way that it automatically positions itself horizontally, for example, when, for example, the footrest is extended or the backrest 3 is reclined.
  • No drives or stops are required to set the angle and depth function (function position setting). The latter are only provided as end stops on the push-out component 8 to prevent them from being pulled out completely and in the swivel part 13 to prevent them from being turned too far.
  • the rollers 5 and 6 are so difficult to design that the push-out components 8 can only be moved with a sufficiently large force, but not with normal use.
  • This "braking effect" against unintentional displacement of the push-out component 8 can be easily achieved in construction if the rollers 5 and 6 can be replaced by sliding shoes or sliding bushes, as shown in FIG. 3 which follows with the plastic sliding bushes 15 and 16. These can easily be designed same t e nd because - as has been shown - the load de legs creates a sufficient "braking effect” as soon and as long as they are launched.
  • FIG. 2 shows a footrest in the starting position from a bird's eye view.
  • the two push-out components 8 are tubes which are firmly connected to one another by a welded-on axis 9.
  • the pivot part 13 is in the vertical position.
  • the scholarauflageteil 12 is narrower than the axis 9 and the Ausschiebebauteil 8.
  • the aperture 11 is wider than the shaft 9 and the Ausschiebebauteil 8. This has the advantage that this aperture 11 in the starting position the entire mechanism, including, in particular, the training s slide components 8 and the axis 9 covered. In the starting position it forms the front of the armchair; the design is absolutely undisturbed.
  • the footrest surface 12 pointing in the opposite direction is not visible at all in this starting position. So it can be cushioned and strongly padded and also with one Upholstery material is covered, which can be less sensitive to dirt than the possibly very expensive and sensitive outer fabric.
  • FIG 3 a seating and reclining furniture is schematically shown, in which the A usschiebebaumaschine are slidably mounted in sliders 14. 8 These Cleitrohre 14 are rigidly attached to the inside of the frame parts 1. At the front end of the two slide tubes 14, a slide bush 15 is attached, while a slide bush 16 is attached to each of the two push-out components 8 at the rear end.
  • the push-out components 8 slide forward through the sliding bushes 15 until the sliding bushes 16 strike the sliding bushes 15.
  • This stop is considered as an end stop to prevent the push-out components from falling out.
  • the push-out components 8 can thus be extended and retracted as far as desired in the sliding tubes 14 between the end positions.
  • the pivoting part 13 is in the schematic representation in the starting position.
  • An elongated hole guide 17 enables the pivoting part 13 to be mounted in the end position 18 of the elongated hole guide on the axis 9, as a result of which the pivoting part 13 can level off approximately vertically to the seating furniture and the panel 11 automatically forms the front side of the furniture. If this footrest is to be brought into operation, this is done in exactly the same way as described in FIG. 1. G advantageous that the soles of the feet on the upper edge of frequentlyaufla is in this hole Lan g construction, can provide e consideration 12 without the pivot member 13 must be pivoted only.
  • FIG. 4 shows a piece of seating furniture whose seat and backrest can be pivoted about an axis 22 mounted in the base frame 1.
  • the axis 22 is mounted in tabs 21 which are attached to the base frame 1.
  • the seat frame 2 is rotatably attached to this axis 22.
  • stabilizing elements for the seat and backrest are omitted; they are generally known and belong to the prior art.
  • the footrest is slidably mounted.
  • the slide tubes 14 are not on the base frame, but on the pivotable about the axis 22 seat frame 2 with attachment means 2ostarr loading fe Stigt.
  • Such fasteners can be screws or straps or clamps; but it can also be a welded construction.
  • the front ends of the push-out components 8 are angled to the axis 9 h in 8 '. This bend allows a Schwen- k ung of the pivoting part 13 from the vertical starting position by more than 9 0 ° relative to the horizontal Ausschiebebau kind 8.
  • the pivoting part can tilt slightly forward 13 below.
  • the slot guide 17 is provided with slight depressions 19, in which the axis 9 is inserted.
  • the depressions 19 are so minimal that they in no way impair the adjustment options by means of the legs.
  • the inner edge 11 'of the diaphragm 11 serves as a stop against rotation of the Swivel part 13.
  • the footrest is in turn attached to the seat frame 2 in such a way that it follows all the movements of this seat frame without losing its own function.
  • the slide tubes 14 are fastened to the seat frame 2 with tabs 26.
  • Push-out components 8, 8 ', 9 and pivoting part 13 and slot guide 17 correspond structurally to the example shown in FIG. 4. Only the adjustment recesses 19 are shown in triplicate here.
  • FIG. 6 shows a schematic illustration of a footrest, in which the push-out component 8 is arranged like scissors.
  • Such scissor designs are generally known and state of the art. Details can be omitted here.
  • FIG. 7 a shows a push-out component 8, 8 'with axis 9 and the pivot part 13 in a side perspective.
  • the non-angled section of the push-out component 8 should be shown in a horizontal position.
  • the lower edge 8 "of this section is to serve as a stop layer for the on-the aperture 11 attachment point 11 ', the diaphragm 11 is -.
  • As shown in Figure 2 - is wider than the shaft 9 and the training sch iebebaumaschinener 8.
  • Due to the axle 9 is a geometrical plane a is laid, while a further geometrical plane b is laid through the lower edge 8 ′′ of the straight section 8 which serves as the stop edge.
  • Both levels run parallel to one another and to the horizontal. Their distance from one another is so large that the pivoting part 13 can be pivoted counterclockwise into a prone angle position.
  • B in Figure 7 is also made of a footrest lateral per- s pektive shown.
  • the geometric plane d runs through the axis 9, while the geometric plane c runs through the stop edge 11 'located on the swivel part. Both planes d and c run parallel to each other and to the horizontal.
  • C between the geometric planes and d is a sufficiently large distance that a pivoting of the level c inellesuhr- ze igersinn beyond the horizontal extent and thus allows a forwardly facing angle adjustment of the pivoting part.
  • FIG. 9 shows a further extension mechanism in tubular construction from a frog's perspective.
  • the holding tubes are welded to angle brackets 30 in this example. These angle brackets 3o have oblong holes 31 running transversely to the seat direction.
  • the angle brackets 3o are screwed onto the frame 2 in their elongated holes with screws 32.
  • the holding tubes 27 are connected to each other with a strut 33.
  • the sliding tubes 14 are connected to each other at their rear end with a strut 34 and screwed to the frame 2 with screws 35.
  • the ejector mechanism is screwed under the seat frame 2 only after it has been covered.
  • the pad springs for example, because they are seated, and because of the padding or other prestresses that may occur, have no effect on the Auschbernechani k, since the differences in tension in the elongated holes 31 are absorbed or compensated for.
  • the distance between the holding tubes 27 To be able to maintain, these are rigidly connected to each other with a strut 33.
  • the slide tubes 14 store j e - but as shown in Figure 8 and described in the holding tubes 27, flexible Only the locks 29 may unfolding le n Practice has shown that it is also possible, and the rear ends of the sliding tubes fourteenth to connect with a strut 34 and screw this strut 34 to the frame 2. As a result, the sliding tubes 14 are stabilized against displacement along their longitudinal axis.
  • the sliding tubes 1 4 then form, together with the strut 34, a fork, in the sliding tubes 14 of which the push-out tubes of the likewise fork-like push-out component 8, 9 slide back and forth. According to the example of the tuning fork, both forks can easily give in and adapt to each other at certain frequencies.
