Definitions

  • the invention relates to a folding armchair or deck chair according to the preamble of claim 1.
  • deck chairs have become widely known for use outdoors, in bathing establishments, green areas, and home gardens.
  • the frame or the frame of these deck chairs is formed by straight wooden rods which, as mentioned in the introduction, are articulated to one another.
  • notches are provided, into which the lower ends of the side rails of the backrest engage, whereby the inclination of the backrest is adjustable.
  • a covering or mat made of a textile fabric is provided, with which a concave or trough-like, continuous back support and seat surface (in steeper position of the backrest) or a continuous lying surface, approximately like a hammock, is formed.
  • a folding armchair or deck chair has proven itself as an actual reclining chair, "that is, for resting in an extended, essentially horizontal position - or else with a sloping backrest, for example when reading for easy reading.
  • Such a folding armchair or deck chair is not - or only very temporarily - suitable as a dining chair, for taking a meal at a dining table, for this requires a chair or armchair with an almost vertical backrest and horizontal seat, with sufficient seat height, in the required
  • Such dining chairs or armchairs are usually rigid, ie not foldable, in accordance with the requirements, but folding chairs with an iron frame are also known, in particular from pub gardens (beer gardens), in which the legs are below the seat cross over like scissors, and a rigid seat with its rear end a n the side rails of the backrest.
  • Such a folding chair has only a single position of use, so it is not suitable as a deck chair for use in a horizontal resting position; apart from that, the backrest is not steep enough.
  • the invention has for its object to provide a folding armchair or deck chair which is suitable for both uses, in which the backrest or the entire deck chair extends from a relatively flat position (rest position) over various steeper positions can be adjusted to the almost vertical dining chair position.
  • This furniture should be collapsible to the smallest possible volume with a simple and robust construction.
  • a groove or guide is provided on the rear legs laterally / below, in each of which a pin engages, which projects horizontally from the lower end of one spar of the backrest. Through this guide, the backrest is forcibly guided on the rear legs, so that all positions are safe and stable.
  • the pins can be supported on the front end of the groove (flattest position of the backrest) and on the rear end of the guide groove (folded position). In between, several catches can be provided for gradual adjustment.
  • the guide groove can be straight, but preferably curved upwards, as a result of which the backrest not only gets into a steeper position, but is also lifted - together with the seat part.
  • the guide grooves preferably each have an upward curvature, in the apex of which at least one catch is provided.
  • subclaims 2 to 7 which are described in more detail in the description of an exemplary embodiment - in order to avoid repetition and for better clarity.
  • a relatively rigid seat part is preferably articulated with its front ends on the front legs, on the same hinge pin as the front ends of the rear legs, and with its rear ends on the side rails of the backrest, below the armrest of the folding armchair.
  • the seat In the almost vertical position, the seat has just the height required for dining. If - after having taken a meal - the supine position is adjusted to a flatter or completely flat resting position, then the front legs also follow this flat position, as was the case with previous deckchairs; however, the seat surface and the armrests, particularly in the front area, reach an altitude that is too low. This is very inconvenient, especially for the elderly or disabled. They have difficulty moving to such a low lying or resting position, especially if the armrests on which they want to be supported when lying down and standing up are also too low above the ground or floor.
  • An important embodiment is therefore characterized in that the lower support surfaces of the front legs are arched backwards / downwards or are designed as a curved surface, etc. that the decrease in the steepness of the front legs corresponds to the reduction in the height of the seat part and armrests (at least in part).
  • the known deckchairs usually include a footrest or lower leg support, the horizontal support part of which is supported on the one hand at the front end of the deckchair and on the other hand on a pair of legs;
  • a folding stool with scissor-like pairs of legs is more convenient for this purpose.
  • a roller or roller is provided at a distance below the seat surface corresponding to the thickness of the folded folding stool. On this roller The folding stool can be pushed under the seat on a rolling basis and stowed away when not in use.
  • the upper ends of the front legs can be simply hinged to the armrests by means of a horizontal hinge pin.
  • the armrests get as high as possible with a slight inclination of the front legs (lying position).
  • the armrests would then also be raised accordingly in the eating position, which would be annoying. It would therefore be important to raise the armrests, especially in their front area, only in the lying position, but not in the eating position.
  • the front legs are not articulated directly on the armrests, but with the interposition of a mechanical coupling part, in particular one swivel arm each.
  • the front legs In the rear position of the swivel arm (lying position), the front legs are supported with their front end faces on an extension of the pivot pin with which the swivel arm is articulated on the armrest, thus raising the armrest.
  • the armrests In the forward position of the swivel arm, i.e. when the front legs are steeper (eating position), on the other hand, the armrests reach a lower position, at most by the distance between the two pivot points of the swivel arm, but above all the different inclination of the Forelegs must be taken into account (reference is made in detail to this in FIG. 2).
  • RoU chairs and also movable garden armchairs are already known.
  • At least one hole is provided on the rear legs and / or front legs for preferably detachably attaching / attaching a wheel.
  • the wheel is attached at the front or rear and depending on the diameter of the wheel or wheels, the height or the inclination of the seat / reclining furniture can be varied.
  • two bores can be provided one above the other at the front and / or rear.
  • a steerable wheel ie, one which can be swiveled about a vertical axis
  • bolts can protrude downward from the headrest, which can be inserted into corresponding holes in the upper cross member of the backrest.

  • the furniture has a seat part 1 and a backrest 2, which are supported by two front legs 3 and two rear legs 4.
  • the seat part 1 is articulated with its front area by means of articulated bolts 5 on the central area of the front legs 3; on the same hinge pin 5 the front ends of the rear legs 4 are articulated, which extend obliquely below / behind to the ground.
  • the lower ends of the side rails 6 are supported on the rear legs 4 (to be carried out).
  • the rear end of the seat part 1 is articulated on the side rails 6.
  • the rear end of the armrests 8 is articulated on the side member 6 of the backrest 2.

  • one side spar 10 of the seat part 1 and one spar 6 of the backrest 2 appear in one plane, both connected to one another by means of joint fitting 7.
  • the armrests 8 (or their vertical part 8a) and the rear legs 4 appear in the same vertical plane. This is followed laterally by a front leg 3 in the next vertical plane.
  • the seating / reclining furniture according to the invention (in the example) is adjustable in four different inclined positions (by snapping in at I, II, II, IV) and also in a "eating" position (FIG. 4, notch V), a further intermediate position (catch VI) is provided here on the upper guide groove.
  • This Fü tion according to the invention is cut in each case on the inside of the rear ne.

  • this guide groove can also be seen in a special fitting plate 16 (FIG. 6), which in turn is attached to the rear legs 4, in which case only the "raw" groove profile needs to be worked into the material of the rear legs 4 .
  • FIG. 6 also shows a variation in that only a single guide groove 12a, 12b, which passes over an essentially vertical region 17 and passes into a vertex 18, is provided in one pass.

  • a notch 20 is provided in the bottom of each of these slots.
  • the backrest 2 When the backrest 2 is set steeply, the rear region of the seat part 1 being raised, the front legs 3 also move into a steeper position, so that the front region of the seat part 1 is also raised, in particular to the normal seat height of a dining chair, and without doing so the seat inclines forwards / downwards, which would result in a very uncomfortable seat.
  • the previous deck chairs - as mentioned at the beginning - have the disadvantage that they are too low above the ground in the flat lying position, so that lying down and getting up is uncomfortable.
  • the seat / reclining furniture according to the invention which is adjustable from the dining position (high seat, steep backrest) into an approximately horizontal rest position, has - in the embodiment according to the drawing - the particular advantage that seat part 1 and backrest
  • the armrests 8 - take up a higher altitude in the resting or lying position, so that lying down and getting up is facilitated.
  • the front legs 3 are arched backwards and downwards to the rear, so that a support surface 21 results as in the case of a crank disk.
  • the support point does not remain unchanged, but the support surface 21 rolls on the ground, as a result of which the seat part and armrests are raised - or. the loss of height due to the inclination is compensated to the desired extent.
  • a hole 21 is provided on the front legs 3 and four holes 22 are provided obliquely one above the other on the rear legs 4.
  • the axis of a wheel 23 can optionally be inserted into each of these holes.
  • the furniture can thus be moved in this way, but in particular the height or inclination can be varied further, depending on which of the holes the wheel axles are inserted into; finally, wheels of different sizes can also be used.
  • swivel arm 25 is once pivoted forward (solid line) and once pivoted backwards - dash-dotted - drawn.
  • the front legs 3 are steeper, the armrests 8 and the seat 1 are raised accordingly. One can therefore rest more comfortably on the higher armrests 8 when resting or raising.

  • the roller 30 together with the sheets 29 is pivoted into the stowed position.
  • a pin 32 on the side of the seat part 1 engages in a circular arc cutout 33 of the sheet 29, so that the pivoting angle of the roller 30 is limited.
