Definitions

  • the present invention relates to a seat with a device for locking the foot ring to the vertical tube, in particular for office, laboratory or community use.
  • Seats are known, particularly chairs or stools, provided with a foot ring which is adjustable in height along the tube of the gas pump or the vertical support tube, to enable a person to sit comfortably for a long period.
  • the foot ring generally consists of a plurality of spokes rigid with a central sleeve which is fixed to the support tube or gas pump tube.
  • the sleeve is fixed by a screw with a knob, the end of which thrusts against the vertical support tube or the gas pump tube.
  • Another locking device uses a frusto-conical sleeve which when the foot ring is loaded grips the entire tube.
  • a drawback of this device is that the sleeve loses its seal with time and a lengthy and laborious operation is required to adjust the position the foot ring relative to the tube.
  • the sleeve is fixed by a knob-attached screw, the end of which engages in one of a plurality of superposed holes provided in the gas pump tube.
  • a drawback of this system is that this device cannot be used in gas pump tubes.
  • the object of the invention is to eliminate these drawbacks by providing a device for connecting the foot ring to the gas pump tube or vertical tube which can be operated easily and comfortably.
  • the device according to the invention is applied to a foot ring 2 provided with four spokes 4 connected to a central sleeve 6 through which the gas pump tube 8 or the vertical support tube for the seat is inserted.
  • one of the spokes 4 is provided with a housing 10 which houses a nylon slide 12, the flanges 14 of which are provided with slotted holes 16 through which a pin 18 is inserted, the ends of which are fixed to the sides of the housing, and on which there is also hinged a lever arm 20 in a hole 22 eccentric to the head 24 of the lever arm.
  • a housing 26 housing a pad 28 of antifriction material.
  • the device according to the invention operates in the following manner.
  • the user rotates the lever arm 20 into the configuration illustrated in Figures 2 and 4 such as to bring the slide 12 into the position most distant from the tube 18, by virtue of the eccentric configuration of the head 24.
  • the sleeve 6 is then made to slide along the tube 8 until the desired position is found.
  • the lever arm 20 is then rotated ( Figures 1 and 3 ) to cause the slide 12 to travel towards the tube 8 with consequent pressing of the pad 28 against the tube to lock it securely against the inner lateral surface of the sleeve 6.
  • the device according to the invention enables the foot ring to be easily and comfortably adjusted relative to the support tube.
