Definitions
- the present invention relates to a chair-lift chair safety device with a crossbar lock-release control device according to the preamble of Claim 1.
- BACKGROUND ART The Applicant's European Patent EP 0 808 757 describes a safety device, in which the front of the chair seat is barred by locking rotation of a cross member of a bracket, hinged by its arms to the chair frame, when the bracket is in the lowered position. This is done by means of a ratchet mechanism, in which a pawl must be released by a Bowden cable from a ratchet disk.
- the connecting member is a cable, a portion of which is fitted with a piston housed in a cylinder filled with a viscous fluid, e.g. liquid or gas, and extends in fluidtight manner through the ends of the cylinder.
- a viscous fluid e.g. liquid or gas
- the damping action is performed on the catch or detent means of the ratchet disk.
- Control device 1 is fitted to a suspension 2 fixed by a clamp 3 to a cable 4 of a chair-lift (not shown) , and is fitted on its bottom end with a chair 5 having a seat 9.
- a bracket 6, comprising two arms 7 (only one shown) and a footrest 8, is fitted in rotary manner to articulated joints 11 (only one shown), the pin of which is fitted with a ratchet disk 12 with a cog 13 adapted to be engaged by a pawl 14 carried by a two- arm lever 15, and adapted to be released in the release direction 16 of bracket 6, or the cross member, by means of a connecting member, e.g. a Bowden cable 17 fixed at its top end to a lever 18 articulated to suspension 2 at 19.
- lever 18 has a roller 20, which cooperates in known manner (not shown) with a guide at the chair-lift departure and arrival stations to lower or raise the Bowden cable and so release and/or engage ratchet disk 12.
- An additional bar 10 is conveniently provided to lock the crossbar of arms 7 far enough away from the seat to leave enough legroom for large-build passengers.
- a portion, or at least one end, of the connecting member or Bowden cable 17 is defined by a rod 21 supporting a piston (not shown) housed inside a cylinder 22 articulated at 23 to a clamp 24 fixed to suspension 2.
- Cylinder 22 may be filled with a fluid, such as gas or liquid, or may be powered electrically in known manner by sliding contacts at the stations. Further changes and variants may be made to the chair-lift chair safety device with a crossbar lock- release control device in accordance with the invention without, however, departing from the scope of the invention as defined in the accompanying Claims.
- the detent means cooperating with the ratchet disk may be appropriately damped.
