Definitions

  • This invention relates to chairs, and more particularly a chair back stand adjustable for height.
  • the main object of this invention is however to supply chairs back with a stand which is not only adjustable for height, but also easy to assemble thanks to the particular shape, disposition and arrangement of its parts.
  • the stand we are proposing presents some construction innovations: the guide elements move axially one relatively to the other, and there is a new way of assembling the mechanism which permits to fix the stand at the possible different heights.
  • the stand is generally indicated by 10 and it supports a chair back 11 - not represented.
  • the stand 10 consists of a fixed element 12 and a movable element 13 which can be moved vertically along the fixed one.
  • the fixed element 12 has a U -shaped section and it is provided with horns 14 in order to be fixed on a chair frame behind the seat.
  • the moving element 13 is guided through the parallel wings 12a of the fixed element and it supports on the upper part at least one strap 15 on which the back 11 is placed.
  • protrusions 16 are provided in the direction of the axis, which match with vertical canal-shaped guides 17 located on the opposite sides of the moving element.
  • the protrusions 16 can be headings obtained in the wings of the fixed element as shown in Figs. 1, 2,and 6.
  • the two elements 12, 13 are combined and reciprocally centered in two directions, which are orthogonal and relatively to the shifting directions of the moving element.
  • the moving element 13 is formed for part of its height by notches 18, which are ordered vertically and interact with a stop lever 19 to fix the equivalent different positions of the moving element 13 along the fixed one 12 of the stand 10.
  • the moving element 13 also has a plate-like portion 20 which extends downwards and it is provided with a vertical fissure 20a closed at the bottom through a bar 20b.
  • the stop lever 19 is assembled on the fixed element 12 in such a way as to oscillate through a supporting block 21 which is to be fixed to said fixed element through pegs and screws 21d. It is remarkable that the supporting block 21 is formed by two parts connected by a joint line 21a - see Figs. 7,8 - in order to form a single complete piece.
  • the joint line 21a permits to open angularly the two parts and to readjust them parallely and to fix the block in the fixed element 12.
  • This block 21 has also a frontal part 21b which inserts in the vertical fissure 20a of the moving element 13 facilitating its guide.
  • the frontal part 21b also constitutes a ledge 21c which interacts with the lower closing crossing bar 20b of this fissure 20a, in order to determine also the maximum vertical shifting of the moving element 13 and to avoid the de-coupling of the two constituting elements.
  • This oscillating axis 22 is formed by two co-axial pivots 22a which protrude from the opposite parts of the lever 19 in a trasversal direction relatively to the lever and the stand 10.
  • the pivots 22a settle in proper seats 21' obtained in the supporting block 21, all this by an angular opening of the two parts of the block -see Fig.8- in order to line up the pivots 22a with the above-mentioned seats 21' and by the reapproaching of the two parts as shown in Fig.7 in order to hold the lever back.
  • the lever 19 is assembled on the block 21 before settling and fixing the block in the fixed element 12.
  • the function of the peg 23 of the stop lever 19 is to occupy the positioning notches 18 of the moving element 13 so to block it at different heights, so that the peg 23 engaging and disengaging the notches according to the oscillating movements of the lever 19 controlled by a pushbutton 24.
  • This control pushbutton 24 consists of a piece -Fig. 5- which has a notched shaft 24a which works through a jerking motion, i.e. by pressure, in a hole created in the bottom part of the lever and elastic sections 24b which lean on the fixed element 12 and act as recovery spring to mantain and re-set the stop lever in the position in which its peg 23 engages the notches.
  • the above-described stand can be partly contained in a protective case.
