Definitions

  • the invention relates to a folding armchair or deck chair according to the preamble of claim 1.
  • a folding armchair is already known from US-A 2 618 317.
  • the disadvantage is that such a folding armchair is not - or only very temporarily - suitable as a dining chair for taking a meal at a dining table. For this you need a chair or armchair with a steep backrest and horizontal seat, with sufficient seat height, in the required stability.
  • Another disadvantage is that the armrests reach a too low height in the flat, inclined rest position. This is very inconvenient, especially for the elderly or disabled. They have difficulty moving to such a low lying or resting position because the armrests on which they want to rest when lying down and standing up are too low above the ground or floor.
  • the guide grooves each have an upward curvature or are connected to such a curvature. This curvature of the guide groove brings the seat part (connected to the backrest) to a higher position when the backrest (for the dining position) is set steeper.
  • the armrests articulated at the upper end of the front legs reach a correspondingly greater height above the ground in the flat position of the armchair or deck chair (i.e. in the rest position).
  • the user can rest on these raised armrests, which makes it easier for him to get in and out of the deck chair.
  • the aforementioned curvature is expediently connected to the guide groove provided below it via a connecting groove. A relatively large height distance is achieved through this connecting groove.
  • the part of the guide groove located at the rear of the connecting groove, which is passed through by the pivot pins when folded, is offset in height relative to the front part of the guide groove, forming a stop. This stop makes it easier to insert the pins into the connecting groove.
  • the guide groove can indeed be formed in the material of the rear leg itself, but advantageously the guide groove, possibly together with the catches and the connecting groove, is provided on a fitting plate or on a plastic part which is attached to the rear legs.
  • the catches can be connected to a narrow neck.
  • the pins can each have a notch at their base.
  • the notches can be omitted and a screw spindle can be arranged between the backrest and the rear legs.
  • the inclination of the backrest is adjusted by means of the screw position and at the same time the backrest is locked in the respective position.
  • a swivel arm or coupling arm can finally be provided between the upper end of the front legs and the armrests, in addition to or instead of the curved design of the supporting surface of the front legs.
  • this coupling arm extends backwards backwards or forwards upwards, the armrests are raised or lowered further.
  • the front legs are supported in the rear position of the swivel arm on an extension of the pivot pin, while in the front / upper position of the swivel arm, the front ends of the front legs are supported directly under the armrests.
  • 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; the front ends of the rear legs 4, which extend obliquely downwards / backwards to the ground, are also hinged to the same hinge pin 5.
  • 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 stone spars 6.
  • this joint 7 is the rear end the armrests 8 each articulated on the side rail 6 of the backrest 2.
  • the upper ends of the front legs 3 are articulated on the front area of the armrests 8.
  • the armrests consist of a (in plan view) wider horizontal part 8a (for comfortably supporting the arms), on the inside of which a vertical part 8b with the joints 9 is provided.
  • 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.
  • a front leg 3 is connected to the side 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 1, 11, 111, IV see FIG. 6) and also in a dining position, notch V), a further intermediate position (catch VI) is provided here on the upper guide groove.
  • This guide according to the invention is cut in each case on the inside of the rear legs.
  • the (lower) guide groove 12 for the various rest positions is connected to the upper guide groove 13 for the eating position via a connecting groove 14.
  • the pins 11 slide in the rear part of the guide groove 12b.
  • the rear part 12b of the guide groove is offset slightly upwards in relation to the front part 12a; In this way, a stop 15 is formed which indicates to the user the position of the guide pins 11 below the connecting groove 14, so that the user can now raise the backrest 6 in order to get into the upper groove 13 via the connecting groove 14.
  • the guide groove 12, 12a, 12b, 13, 14, with the notches I-VI, can be cut directly into the wood of the rear legs 4.
  • 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 incorporated into the material of the rear legs 4.
  • FIG. 6 also shows a variation in that only a single guide groove 12a, 12b passing through a substantially vertical region 17 into a curvature 18 is provided.
  • the notches of the groove are provided with a narrowed neck 19.
  • a push button action is achieved, i.e. the guide pin 11 can only be lifted out of the corresponding detent against increased resistance.
  • a notch 20 is provided in the bottom of each of these notches.
  • the front legs 3 When steepening the backrest 2, the rear area of the seat part 1 being raised, the front legs 3 also move into a steeper position, so that the front area of the seat part 1 is also raised, in particular to the normal seat height of a dining chair, without that the seat inclines forward / down, which would result in a very uncomfortable seat.
  • the previous deckchairs - 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 can be adjusted from the dining position (high seat, steep backrest) to an approximately horizontal rest position, has - in the embodiment according to the drawing - the particular advantage that the seat part 1 and backrest 2 - and in particular the armrests 8 - in the resting or lying position assume a higher altitude, so that lying down and getting up is easier.
  • the front legs 3 are arched backwards and downwards at the back, 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, which raises the seat part and armrests - or the height loss due to the inclination is in the desired position Extent balanced.
  • a hole 22 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.
  • the front legs 3 are not articulated directly to the armrests 8, but rather via a swivel arm 25 or crank arm. Depending on the angular position of the swivel arm 25, the armrest 8 is raised or lowered.
  • the swivel arm 25 is swiveled forward once (solid line) and swiveled backwards once - dash-dotted - drawn.
  • the front legs 3 are steeper, the armrests 8 and the seat 1 are raised accordingly. So you can rest in a resting position when resting or more comfortably on the higher armrests.
  • an extension of the pivot pin 9 comes into contact with the end face of the front legs 3 in the example case.
  • the front legs 3 are directly under the armrest 8 or 8a, in particular in a recess or recess 26 Armrest supported.
  • a traction means is provided between the lower cross member 40 of the backrest 2 and a rear strut 41 between the rear legs 4.
  • a screw spindle 42 can be provided for this purpose, which is connected via a bendable shaft 43 to a rotary handle 44 at the front under the seat part 1.
  • the guide groove 12 has no notches.
  • the catches can be covered by a pivotable sheet (Fig. 9).
