Definitions

  • the memo" dsclosed relates a new 58 Field of Search 297/162 160 411 161 disposed for Supporting a Working surface along one 297/417; 248/441, 460, 38, 40, 200, 186, We of 3 205; 108/1, 50 2 Claims, 6 Drawing Figures 1 ARM FOR A CHAIR
  • the present invention concerns an arm to be applied to the side of chairs, easy chairs and the like, for supporting a small writing table by means of a pivot joint inclined forwardly, upwardly and outwardly so that, by a single rotation about said pivot, the table executes a double movement passing from the vertical position at the side of the chair to a horizontal position at the front of and above the seat and also rotating through 90 in the plane in which it is contained to permit writing on the table itself.
  • the two limiting positions assumed by the table correspond to the stable positions of the inclined pivot as stated, in the actual seat of the arm, the said rotation of which is sufficient to locate the table in a stable horizontal or vehicle position, both during use and when not in use.
  • the pivot arm inclined according'to the present invention minimizes the disadvantages of conventional writing tables which are usually supported by hinges having a horizontal axis and by pairs of vertical and horizontal hinges which may require means for locking in position or represent a considerable obstacle when in a position of non-use.
  • an arm to be applied to the side of a chair or the like, for supporting a small writing table in which the upper end of the arm has a bore with an axis inclined forwardly, upwardly and outwardly, said bore containing a rotatable pivot connectable to the table, the axis of which assumes the same inclines as the bore so that, by
  • the table passes from the horizontal working position to a substantially vertical position of non-use.
  • FIG. I is a side plan view of a chair with portions removed in which the arm of the present invention is mounted with the table in the horizontal position of use;
  • FIG. 2 is a similar view to that of FIG. 1 illustrating the chair and arm with the table in the position of nonuse;
  • FIG. 3 is a partial side plan view relatively enlarged and showing the arm with the table in horizontal use position;
  • FIG. 4 is a partial rear plan view relatively enlarged and showing the arm with table in horizontal use position
  • FIG. 5 is a partial top plan view relatively enlarged and showing the arm with the table in phantom horizontal use position
  • FIG. 6 is a partial top plan view relatively enlarged and showing the arm with the table in rotated non-use position.
  • FIGS. 1 and 2 show a chair 1 having side means for connections 2 to which the arm 3 is applied, provided at its upper end with a writing table 4 which may be rotated from the position of use, horizontal, as shown in FIG. 1, to the side position of non-use, as shown in FIG. 2.
  • FIG. 3, 4 and 5 show on a magnified scale the arm alone with the table according to the invention and, to a limited extent, the area for connection to the chair, easy chair or the like.
  • This end is provided with a bore 7 the axis XX of which is inclined forwardly, as shown in FIG. 3, upwardly as shown in FIG. 4 and outwardly on the right of the chair, as shown in FIG. 5.
  • Rotatable within this bore is a pivot 8 connected to a plate 9 to which the table 4 is strongly secured.
  • the position of said pivot 8 relatively to the plate 9 is shown in said FIGS., the axis of said pivot still being the axis XX of the bore 7 when considering the plate 9 according to the three views shown in FIG. 3, vertical at the side in FIGS. 4, vertical on the left and in FIG. 5, from above, the pivot 8 is provided with the same inclines of the axis XX relatively to the said three planes.
  • the plate 9 is'preferably arranged so as to be parallel with its own sides at the sides 4a, 4b and 4c of the table 4.
  • the said table 4 has a side 4d inclined relatively to the other three, to permit writing with a sheet of paper at an incline as usual.
  • the connecting plate 9 By locating the connecting plate 9 near the sides 4a, 4b, it is also possible for the side 4a, which becomes the upper side when the table is in the position of non-use, to be at a sufficiently low level not to constitute an obstacle to the arm of the person using the chair.
  • the values of the inclines of the axis XX relatively to the vertical, horizontal and lateral planes may be established on the basis of the total value of the rotation, i.e., through the initial position to the final position, assumed by the table.
  • the axis XX may assume an angle of approximately 32 upwardly, approximately 43 outwardly and approximately 33 forwardly.
  • a chair mountable arm and writing table which comprises in combination, an arm having means for securing to the side of a chair, said arm having a forwardly inclined body member terminating in an end portion, said end portion having a bore the axis of which is inclined forwardly, upwardly and outwardly relative to a horizontal plane, a rotatable cylindrically pivot disposed within the bore, one end of said pivot being connected to a writing table, said writing table being pivotally rotatable backwardly, outwardly and downwardly from a horizontal writing position to a ver- 5 outwardlytical non-use position.
