Definitions

  • the present invention relates to a device which is intended to be fitted to an armchair or like article for the purpose of converting the armchair to a swivel armchair.
  • swivel armchairs which are presently available on the market are encumbered with certain drawbacks.
  • the general appearance of such armchairs does not match the appearance of conventional suites of furniture and the chairs also require a large amount of space for transportation and storage purposes.
  • the swivel mechanism of a swivel armchair is an integral part of the chair and must be scrapped together with remaining chair parts when these become worn.
  • the object of the present invention is to eliminate the aforesaid drawbacks and to provide a device which can be fitted to a conventional or standard armchair such as to convert the armchair to a swivel armchair without appreciably changing its original appearance.
  • the device requires only a small transportation and storage space and can be switched to a new armchair when the old armchair is worn out.
  • a steel plate 2 is adhesively bonded concentrically to a larger circular plate 1 made of hardened glass or plastic.
  • a steel shaft 3 is welded to the centre of the steel plate so as to extend vertically therefrom.
  • Mounted for rotation on the shaft 3 are four arms, which comprise two arm-pairs, each in the form of mutually crossing tubular members 4 and 5 and each of which can be rotated horizontally about its respective centre point, at which through-passing holes have been drilled for accommodating the shaft 3.
  • the tubular members are held on the shaft by means of a cotter pin 7.
  • the centre part of the tubular member 5 has been removed and replaced with two flat plates 6 welded to the top and bottom sides of the tubular member, so that the two tubular members will lie in one and the same plane.
  • the length of the piece of tubular member removed is slightly longer than the outer diameters of the tubular members 4 and 5, therewith enabling the angle between the tubular members to be varied from about 60° to about 120°, which is necessary in order for the inventive device to be fitted to different armchairs.
  • rollers such as ball bearings 8 which are mounted such as to roll against the plate 1 when the cruciform tubular members are rotated around the shaft.
  • rollers such as ball bearings 8
  • the telescopic tubes have welded to the outer ends thereof carrier means in the form of angle irons 11 provided with holes 12 to enable the angle irons to be secured to the undersurface of the legs of the armchair, which are therewith fixated at a level of some centimeters above the level of the floor on which the plate 1 rests. Subsequent to having secured the angle irons, stop screws 10 are tightened so as to lock the telescopic tubes and to render the legs of the armchair stable.
  • Figure 3 illustrates an alternative embodiment, in which the plate 1 is replaced by an annular 13 having spokes 14 which accommodate the shaft 3 at their radially inner ends.
