Definitions

  • the invention relates to a folding armchair specified in the preamble of claim 1.
  • Such folding armchairs are known (G B-A-215 551).
  • a flexible sheet of textile material or the like is provided, which forms both the seat and a backrest and the two ends of which are each fastened to a crossbar.
  • the two crossbars are used in holders at the upper end of the longer rear part or in holders at the upper end of the shorter front part.
  • Both the two struts for connecting the upper ends of one strut cross to the rear part or to the front part and the two struts for connecting the upper ends of the other strut cross to the back part and the front part respectively extend away from the back part and from the front part beyond the articulated upper crossbar end and are articulated in the middle between the two upper crossbar ends to be pressed into a horizontal, stretched position in which they serve as armrests and rest with their free ends on the two upper crossbar ends as well locked together.
  • the flexible web cannot be tensioned. Toggle linkages are not provided.
  • the prior art also includes folding armchairs with a back or a front part and two rods for the articulated connection of the back and the front on one side or on the other side to one another, the seat being formed by a flexible web of textile material or the like , which is stretched between the back part and the front part, a backrest at the height of the two armrests is rotatably mounted on the back part and the two linkages are arranged below the seat.
  • the two linkages are each formed by a horizontal pair of struts and two struts crossing each other, the pair of struts being articulated with the two outer ends on the rear part or on the front part and its two struts being articulated to one another at the adjacent ends, while the other two struts are each hinged at one end to the lower end of the rear part or the front part and at the other end to the strut articulated on the front part or on the strut articulated on the rear part of the horizontal strut pair and run accordingly at an angle.
  • a further pair of horizontal struts is provided, which extends above the linkage on the relevant side, is also articulated with the two outer ends on the back part and on the front part and has a central joint axis, through the latter a vertical additional strut is articulated to the linkage or the lower pair of horizontal struts at its central hinge axis and forms an armrest (DE-C-488 630).
  • the invention has for its object to provide a folding armchair, which has a simple structure of relatively few, simple components and ensures a high level of seating comfort, in particular can also be designed so that an unimpeded penetration of the user's feet under the seat is possible and a soft back support is imparted to the user, and which is simply together can be folded and unfolded, without any risk of pinching and with an audible click in the unfolded position of use, in the folded position only requires a small amount of space and in the unfolded position of use is exceptionally stable, in particular can also be moved without the risk of collapsing .
  • the folding chair shown consists essentially of a back part 1, a front part 2, a seat 3, two armrests 4, two scissor-like movable strut crosses 5, two toggle linkages 6, two pairs of struts 7, 8 and a backrest 9.
  • the back part 1 is designed as a flat frame with two mutually parallel, elongated supports 10 and 11 which are fastened to one another by two mutually parallel cross bars 12 and 13.
  • the shorter front part 2 is also designed as a flat frame with two mutually parallel, elongated supports 14 and 15, which are fastened to one another by a cross bar 16.
  • the two frames each have an H-shaped shape.
  • the seat 3 is formed by a flexible web 17 which, when the folding chair according to FIGS. 1 and 2 is in use, extends transversely and approximately horizontally between the back part 1 which is approximately perpendicular to the floor and the front part 2 which is also approximately perpendicular to the floor, expediently under a slight tension.
  • the two ends of the flexible web 17 are each attached to the lower crossbar 13 of the rear part 1 and to the crossbar 16 of the front part 2.
  • the backrest 9 also consists of a flexible web 18 which is stretched between two resilient legs 19 and 20 of two V-shaped brackets 21 and 22, the two legs 19 and 20 being received in two transverse loops at the two ends of the flexible web 18 can.
  • the two brackets 21 and 22 are each gripped by an inner pin 23 or 24 at the free upper end of the adjacent support 10 or 11 of the back part 1 and fixed with the other leg 25 on the back part 1, so that the two resilient legs 19 and 20 to project obliquely downward from the associated inner pin 23 or 24 and onto the front part 2, as can be seen in FIG. 2, and in the use position of the folding armchair there is a soft back support for the user as a whole.
  • the two scissor-like movable strut crosses 5 each consist of two struts 26 and 27 of equal length, which are pivotally connected to one another about an axis 28 parallel to the transverse rods 12, 13 and 16.
  • the two struts 26 and 27 are each pivotably pivoted about an axis 29 or 30 parallel to the axis 28 at the lower end of the rear part 1 or the front part 2, specifically with a strut cross 5 on one side of the folding chair and at another strut cross 5 on the other side of the folding chair, that is, on the inside of the lower ends of the two elongated supports 10 and 14 of different lengths or the two elongated supports 11 and 15 of different lengths.
  • each strut cross 5 or the two struts 26 and 27 of the same are through a strut 8 or a strut 7 with the upper end of the front part 2 or with the back part 1 on its upper crossbar 12 on the respective side of the folding chair articulated.
  • Each strut 7 is pivoted about two axes 31 and 32 parallel to the axis 28 on the inside of the adjacent support 10 or 11 of the rear part 1 or on the outside of the upper end of the strut 27 of the associated strut cross 5.
  • Each strut 8 is also pivoted about two axes 33 and 34 parallel to the axis 28 on the inside of the adjacent support 14 or 15 of the front part 2 or on the outside of the upper end of the strut 26 of the associated strut cross 5.
  • the two toggle linkages 6 are each provided between the two upper ends of the one or the other strut cross 5 or the two axes 32 and 34 of the two struts 26 and 27 thereof in order to secure the two strut crosses 5 in the unfolded use position of the folding chair according to FIG. Keep 1 and 2 spread.
  • Each toggle linkage 6 consists of a longer first strut 35 and a shorter second strut 36, each pivotable at one end about the axis 34 or about the axis 32 inside at the upper end of the strut 26 of the associated strut cross 5 or outside at the upper end the strut 27 of the associated strut cross 5 are articulated.
  • the shorter second strut 36 is about an axis 37 parallel to the axis 28 pivoted on the outside of the longer first strut 35, approximately in the middle thereof.
  • the longer first strut 35 supports the armrest 4 on the relevant side of the folding chair.
  • each toggle linkage 6 in the illustrated depressed position of each toggle linkage 6, the common hinge axis 37 of the first strut 35 and the second strut 36 thereof lies below the connecting line of the two hinge axes 34 and 32 between the two upper ends of the associated strut cross 5 and the first or second strut 35 or 36 and the longer first strut 35 rests with its free end 38 on the upper end of the associated strut cross 5 or strut 27 thereof, on which the second strut 36 is pivotable about the axis 32 is articulated.
  • the folding armchair is very easy to operate. To fold it up, it is sufficient to grasp the two armrests 4 and pull them up so that the two middle struts 35 pivot upwards about their two axes 34 and the two toggle linkages 6 fold up, the tension mentioned in the flexible web 17 having to be overcome, which rises until the three hinge axes 32, 34 and 37 of each toggle linkage 6 lie on the same straight line and then falls again. After this extended position of the two toggle linkages 6 has been exceeded, the back part 1 on the one hand and the front part 2 and the armrests 4 on the other hand can be completely folded against one another via the intermediate position according to FIG. 3, as shown in FIG. 4, after the backrest 9 has been removed beforehand. In this folded position, the folding armchair takes up very little space. As can be seen from FIG. 4, the maximum width corresponds approximately to twice the width of the carriers 10, 11, 14 and 15 of the same width.
  • the folding armchair is very comfortable. Based on the described shape of the H-shaped frame-menarti g en front part 2, the user can freely Tekken his feet under the seat. 3
  • the backrest 9 inserted after the folding armchair is folded into the use position in the back part 1 is a very pleasant back support for the user because it is soft and flexible on the whole and the user with his back in contact with no cross strut or crossbar of the back part 1 is coming.
  • the folding armchair is characterized by a very simple structure made up of relatively few, simple components. While the two V-shaped brackets 21 and 22 are preferably made of spring steel and the two flexible tracks 17 and 18 are preferably made of textile material, the other components, apart from the axes mentioned, can be made of wood or plastic, for example.
