Definitions

  • the present invention relates to a chair with back adjustable as to height and orientation.
  • Seat and back generally have ergonomic shapes for a comfortable sitting.
  • the possibility to adjust the back as to height is obtained by making the upright element telescopic, while the orientation possibility is obtained by connecting the back to the upright element through pivoting pins.
  • the prior art provides for constructional designs of the kind shown in Figs. 1 to 3 where the upright element generally indicated with numeral 1, comprises a sheath 2 in which a rod 3 supporting at its end the back 4 is telescopically sliding.
  • connection of rod 3 to the back 4 is obtained through a flange 5 which, as shown more particularly in Figs. 2 and 3, is provided with holes 6 for screws 6a connecting to the back 4 and slots 7 pivotally receiving pins 8 provided at the end of rod 3.
  • Coupling of pins 8 in the corresponding slots 7 is a nip free coupling so that the back 4 may be rotated along both directions indicated by arrow 9 around the longitudinal axis X defined by pins 8.
  • a first drawback consists in that to obtain orientation of the back it is necessary to use the flange connecting the upright element to the back and this involves an increase of the manufacturing costs of the chair.
  • Another drawback consists in that application of the flange to fix the back to the upright element is obtained by screws and this also causes an increase of the assembling costs.
  • a further drawback consists in that to obtain also the height adjustment of the back, the upright element comprises an outer shell and a telescopically sliding inner rod with a further increase of the manufacturing cost.
  • the present invention aims at overcoming the above mentioned drawbacks.
  • a first object of the invention is to provide a chair with movable back adjustable as to height and orientation, having a lower number of components in comparison with equivalent chairs of the prior art.
  • Another object of the invention is to provide a chair allowing the height adjustment of the back using an upright element made of a single piece.
  • a further object of the invention is to provide a chair easier to be carried out in comparison with equivalent chairs of the prior art.
  • a last but not least object of the invention is to provide a chair easier to be assembled in comparison with the known chairs.
  • the possibility of orienting the back relative to the upright element is obtained by coupling of pins made in the upright pivotally coupled in corresponding slots made in the back, wherein coupling of the pins in the corresponding slots is obtained by elastic deformation of the back.
  • the back is therefore made of elastically yielding material such as plastic material or flexible metal sheet.
  • Blocking means allow to fix the upright element and consequently the back supported thereby in the desired adjustment position.
  • the chair of the invention is of easier and cheaper construction.
  • Figs. 4 and 5 where it is generally indicated with reference numeral 10.
  • the chair comprises a seat 11 resting on a bearing structure 12 leaning on the ground and a back 13 which is connected to an upright element 14 associated to the seat 11.
  • the upright element 14 may belong to the bearing structure 12 instead of the seat 11.
  • said back 13 and said upright element 14 are mutually connected through joint means generally indicated with numeral 15, that can be removably snap coupled by elastic deformation of the said back 13.
  • Said joint means 15 as shown more particularly in Fig. 5, comprise projecting elements 16 belonging to the upright 14 and slots 17 belonging to the back 13. More particularly as shown in Figs. 6 to 8, the projecting elements 16 comprise a couple of pins 16a, 16b mutually coaxial along a longitudinal axis Y defined thereby and protruding from opposite parts of the upright element 14 of which they are part.
  • Said pins are inserted in the corresponding slots 17 consisting of holes 17a, 17b also mutually coaxial along a longitudinal axis Z and made in corresponding bulges 20, 21 made in the back 13.
  • Said bulges 20, 21 are spaced from each other by a dimension 22 at least equal to the width 23 of the upright element 14 that is housed between the bulges 20, 21 when the pins 16a, 16b are coupled in the corresponding holes 17, 17b.
  • the back 13 is made of yielding material, for instance plastic material or steel sheet, so that coupling to the upright 14 as already stated, occurs by elastic deformation of the back 13 allowing to insert the pins 16a, 16b in the corresponding holes 17a, 17b.
  • Coupling between the back 13 and upright 14 is removable because it is sufficient to apply again forces F1, F2 to the ends of the back 13 to allow separation from the corresponding upright with movements opposite to those above described.
  • pins instead of being made in the upright element, are made in the back and therefore the corresponding holes into which they are inserted are made in the upright element instead of the back.
  • the pins and/or the upright will be made of elastic and yielding material.
  • FIG. 9 Another constructional variation of the chair of the invention generally indicated with numeral 30 is shown in Fig. 9 where one can see that it is different from the previously described embodiment for a different implementation of the joint means generally indicated with numeral 35 of the back 33 to the upright 34.
  • joint means 35 comprise:
  • connection between the back 33 and upright 34 is a snap connection exploiting the elasticity either of the upright 34 in connection with finger 36a or the back 33 in connection with recesses 37a or both.
  • FIG. 10 and 11 Another constructional variation of the chair of the invention is shown in Figs. 10 and 11 wherein the chair generally indicated with numeral 40 is different from the previously described embodiments because the upright element 44 supporting the back 43, is inserted passing through a hole 42 made in the seat 41 where it can be blocked through fastening means 50.
  • Said fastening means 50 comprise a slot 45 made in the upright 44 receiving a screw 46 having an end 46a coupled to a nut screw 47 fixed to the seat 41 and the opposite end 46b provided with a handle 48 accessible by the user to actuate the screw 46 to fix the upright 44 once the back 43 is arranged at the desired height.
  • the upright element may be connected to the bearing structure arranged resting on the ground instead of being connected to the seat.
