Definitions

  • the present invention relates to a so-called fitter's trolley of the kind which comprises a wheeled chassis on which there is arranged a seat and a back rest which can be swung smoothly and continuously from a horizontal, collapsed position to a vertical or raised position.
  • a fitter's trolley of conventional type according to the pre-characterising portion of Claim 1 is, for example, known from US-A-2 703 717.
  • a fitter's trolley constructed in accordance with the invention has a locking arrangement for locking the back rest in desired positions of adjustment, said locking arrangement including a locking lever which can be readily reached from one side of the chassis, a rotatable or twistable locking rod which has a screw thread at one end thereof and which is secured to the locking lever, and a nut which is attached to a cylindrical locking head and which co-acts with the screw-threaded end of the locking rod, the locking arrangement further including a support rod or bar, which is movably mounted on the back rest and displaceable in the direction of the longitudinal axis of the chassis, is passed through the locking head and is capable of being locked thereto by means of the locking rod when applying the locking lever.
  • the trolley illustrated in Figure 1 includes a wheeled chassis 10 on which there is arranged a seat (seat cushion) 11 and a pivotal back rest 12.
  • a support rod or bar 25 which is displaceable in the longitudinal direction of the chassis, is secured to the rear side of the back rest 12, via a pivotable arm 14, in a manner such that when the back rest is rotated from a horizontal, collapsed position to a raised position the support rod or bar 25 is moved axially in the longitudinal direction of the chassis 10 (from left to right) through two sleeves attached to the chassis 10, one of which sleeves is indicated opposite the rear cross beam of the chassis and is hidden from view by the seat-construction.
  • the back rest is lifted smoothly to selected positions, by means of a spring 13.
  • the back rest 12 can be firmly locked in a selected position by means of a locking arrangement, illustrated more clearly in Figure 2, by applying a locking lever 21.
  • the locking arrangement includes said locking lever 21, a rotatable locking rod 22 which is attached to the locking lever, the left-hand end of said locking lever being provided with a screw thread, and a nut 23 which is attached to a cylindrical locking head 24 and intended for co-action with the screw threaded end of the locking rod 22.
  • the locking head 24 is stationarily arranged relative to the chassis 10, via two steel tubes 20.
  • Located between the locking rod 25 and the screw threaded end of the locking rod 22 is a relatively long locking plate 26 which is placed in the locking head 24 and which is movable in the transverse direction of the chassis. The friction prevailing between the locking plate 26 and the support rod or bar 25 provides effective locking of the back rest in selected positions.
