  • the panels forming the front and back of these chairs are extending from a common base line with the disadvantageous that the seat and the backrest will not be connected. That implies the drawback that these known chairs are uncomfortable to use unless costly and labour-intensive special actions are taken. As consequence the known chairs are difficult and time-consuming to fold from their blanks.
  • a first aspect of the present invention providing an foldable chair which easily and quickly can be folded from a blank.
  • a second aspect of the present invention providing an foldable chair where the seat and the backrest automatically cohere when folding the blank.
  • a third aspect of the present invention providing an foldable chair which is comfortable to use.
  • a fourth aspect of the present invention providing a strong and stabile foldable chair which can be folded from a blank without utilizing joining means like e.g. glue, sheet-formed joining means or other means for reinforcing the chair.
  • a fifth aspect of the present invention providing an foldable chair which has a significantly reduced thickness and which occupies a relatively small amount of storage space when unfolded.
  • the novel and unique features of the invention consists in the fact that in the blank for folding the chair are the seat panel and front panel interconnected via a first transverse folding line, the backrest panel and back panel via a second transverse folding line and the seat panel and backrest panel via a third transverse folding line.
  • the chair of the invention is therefore stronger and more comfortable to use than the prior art foldable chairs.
  • the folding up of the blank can moreover take place easily and quickly and without utilizing other joining means like e.g. glue.
  • the blank is preferably cut from a single sheet of cardboard, paper board, plastics or plywood as this will render a flat blank according to the invention which is not only inexpensive to fabricate, but also light and therefore easy to carry.
  • the blank In the unfolded state the blank has a relatively small thickness and the blank will therefore occupy a relatively small amount of storage space when unfolded.
  • the blank can be folded into a very comfortable and strong chair without requiring any additional reinforcement means, such as an additional sheet-part added to a specific section of the blank by e.g. glue in order to provide a reinforced back panel.
  • additional reinforcement means such as an additional sheet-part added to a specific section of the blank by e.g. glue in order to provide a reinforced back panel.
  • the blank 1 shown in fig. 1 is in the steps shown in fig. 2 through 6 folded up to the nearly finished chair 2 of the invention shown in fig. 6 .
  • the blank is at least mainly flat and may be stamped out of a sheet of e.g. cardboards and it comprises a number of folding lines between a number of panels having each their function in the folded chair.
  • the seat panel 3 is connected to the front panel 4 via a first transverse folding line 5, while the backrest panel 6 is connected to the back panel 7 via a second transverse folding line 8.
  • first and second transition panel 9 and 10 which are interconnected via a third transverse folding line 11, whereby the first transition panel 9 is connected to the backrest panel 6 via a fourth transverse folding line 12 and the second transition pane 10 is connected to the seat panel 3 via a fifth transverse folding line 13.
  • the seat panel and backrest panel be directly interconnected via a common transverse folding line, (not shown).
  • the front panel 4 is connected to a first and second side front panel 14 and 15 via a first and second lateral front folding line 16 and 17, while the back panel 7 is connected to a first and second side back panel 18 and 19 via a first and second lateral back folding line 20 and 21.
  • a first front joining panel 22 is connected to the first side front panel 14 via an oblique first front joining folding line 23 and to the seat panel 3 via a lateral first front joining folding line 24, and a second front joining panel 25 is connected to the second side front panel 15 via an oblique second front joining folding line 26 and to the seat panel 3 via a lateral second front joining folding line 27.
  • the first front joining panel 22 consists of two first joining parts 22' and 22" which are interconnected by means of a third front joining folding line 28 while the second front joining panel 25 consists of two second joining parts 25' and 25" which are interconnected by means of fourth joining folding line 29.
  • the joining part 22" is connected to the second transition panel 10 via a foldable front fixing panel 30, which is connected to the second transition panel 10 and to the second joining part 22" via other fixing folding lines 30' and 30".
  • the joining part 25" is connected to the second transition panel 10 via a foldable front fixing panel 31, which is connected to the second transition panel 10 and the second joining part 25" via other fixing folding lines 31' and 3".
  • a first back joining panel 32 is connected to the first side back panel 18 via an oblique first back joining folding line 33 and to the backrest 6 via a lateral first back joining folding line 34
  • a second back joining panel 35 is connected to the second side back panel 19 via an oblique second back joining folding line 36 and to the backrest panel 6 via a lateral second back joining folding line 37.
  • the first back joining panel 32 is foldable about two oblique back joining folding lines 32', while the second back joining panel 35 is foldable about two other oblique back joining folding lines 35'.
  • the folding lines 32' and 35' are limiting each a fixing panel 38 and 39, respectively.
  • the front panels, 4,16,17 are each connected to a front base panel 40 via a transverse front base folding line 41 and the back panels 7, 18, 19 are each connected to a back base panel 42 via a transverse back base folding line 43.
  • a first and second flab 44 and 45 with closing means 46 is connected with the first and second side front panel 14 and 15 via lateral flap folding lines 47 and 48.
  • a third and fourth flab 49 and 50 with closing means 51 is connected with the first and second side back panel 18 and 19 via lateral flap folding lines 52 and 53.
  • the third and fourth flab 49 and 50 are each extending into free tabs 54 which each is connected to the remainder of the respective flab via a tab folding line 55 and is equipped with a closing means 56.
  • the folding up of the blank 1 takes place in the following way.
  • the free tabs 54 of the flabs 49 and 50 of the back have moreover been bent about their tab folding lines 55 and been attached to the flaps 44,46 of the front as the closing means 56 of the free tabs are engaging the closing means 46 on the flabs 44,45 of the front.
  • the back joining panels 32,35 have been bent inwards about their respective oblique back joining folding lines 32', 35', simultaneous with being bent about the lateral back joining folding line 34,37 at the backrest panel 6 and the oblique back joining folding lines 33,36 at the side back panel 18 and 19.
