Definitions

  • the present .-nvention relates to a traveller car for securing lines or blocks at sheeting of the sail or rig of sailboat t.o essentially T-shaped tracks mounted on the sailboat, said car being provided with opposite sup ⁇ port members adapted to engage beneath the two opposite, protruding side edges of the track, said car and tracks having mutually, coacting guide faces for ensuring a longitudinal displacement of the car and for preventing displacement perpendicular thereto, when said car is mounted on the track.
  • the tra ⁇ veller car ha to be mounted in a predetermined position on another trick arranged at a different position on the sailboat, and the traveller car then has to be guided onto the end of the other track and moved to the prede ⁇ termined position.
  • This work process is particularly difficult and time-consuming on a sailboat at sea.
  • US patent No. 4,719,869 discloses a traveller car of the type stated in the introduction, wherein the block usu ⁇ ally attached to the traveller car comprises a base plate releasably attached to the traveller car per se and being in engagement with a groove therein. The tra ⁇ veller car and the attached base plate may then be moved from one traveller car on a track to another traveller car on another track arranged at a different position on the boat.
  • the system requires the use of as many traveller cars as tracks, thus being expensive in initial costs and not solving the above problem.
  • the traveller car is characterised in that the car comprises at least two separate parts ensuring in a mutually locked position that the car is retained in the mounted position, the mentioned mutually coacting guide faces being in engage ⁇ ment with eac , other, and one of said parts ensuring in a releasing position that the coacting guide faces may be disengaged from each other, whereby the car may be moved to and ** ro the mounted position in a direction es- sentially perpendicular to the track.
  • a traveller car which may be quickly and easily removed from or mounted on a track without displacement of the traveller car in the longi ⁇ tudinal direction of the track to the end of the track and past said end, when the car is to be removed or in the opposite direction when the car is to be mounted.
  • the traveller car may thus be moved from one track to another on the boat during sailing in a particularly easy manner or quickly removed after sailing, for in ⁇ stance in order to avoid theft.
  • a total weight saving in deck equipment of the boat is obtained, as a substantially smaller amount of cars is required than at hitherto known systems.
  • one of the separate parts is a rigid car body and at least one part is a support mem- ber comprising the guide faces at one side of the car, the support member and/or the car body being provided with a locking means being activated externally for re ⁇ taining the support member in the mounted position of the car and the car body may be provided with recesses or openings for guiding the support member, when after the release of the locking means said member is to be removed from the car body or is to be arranged at mount ⁇ ing.
  • the traveller car is thereby particularly simple to manufacture and maintains essentially the same outer di- mensions and strength as the hitherto known types of traveller cars .
  • the support member in its mounted position may be adapted to engage in opposite, grooved-shaped recesses on the car body and/or on the track, and may subsequent to release of the lock ⁇ ing means be disengaged from said recesses by displace ⁇ ment in the longitudinal direction of the track.
  • the support member may comprise a plurality of roller bodies retained in a holder being in locked engagement with the car body, preferably by means of a T—groove connection.
  • the roller bodies may advan ⁇ tageously be formed by balls retained in a holder provi ⁇ ded with a circumferential groove, wherein the balls may circulate.
  • the support member is a sli ⁇ derod, preferably with a circular cross—section, whereby the traveller car is able to resist particularly heavy load and still have a good sliding ability on the track.
  • the support mem— ber may be a sliderod gripping around the protruding side edge of the track and preferably have a U-shaped cross—section, whereby the traveller car is particularly easy and inexpensive to manufacture.
  • one end of the sup— port member may comprise a locking means protruding in the mounted position, preferably a spring—loaded pawl means, which is particularly easy to use.
  • one of the parts may be formed by two mutually hinged support members to form the car body, and the second part may be formed by a locking bolt extending in the locked position through the hinge arrangement essentially in the mentioned lon ⁇ gitudinal direction.
  • the axis of rotation of the hinge arrangement extends in the mentioned longi ⁇ tudinal direction in the mounted state of the traveller car essentially perpendicularly above a side edge of the track, whereby the traveller car is particularly easy to manufacture .
  • the support mem ⁇ ber may for instance comprise other types of slide or roller means :han the ones described herein.

Abstract

Un chariot mobile (20) est conçu pour maintenir les cordes ou les poulies sur un rail (1) en forme de T lors du bordage de la voile ou de la voilure d'un bateau à voiles. Le chariot (20) comprend un corps de chariot (21) avec une tige de glissement fixe (22') et une tige de glissement amovible (22) maintenue au moyen d'un dispositif de blocage (23) à ressort. Après le détachement du dispositif de blocage (23) la tige de glissement amovible (22) peut être enlevée du corps de chariot (21) dans la direction longitudinale du rail (1); après quoi le corps du chariot (21) peut être soulevé vers le haut en dehors du rail (1) sans devoir déplacer le chariot mobile (20) au-delà d'une extrémité du rail (1). Le chariot mobile (20) peut alors être monté à n'importe quelle position sur un rail différent (1) disposé à un autre endroit du bateau.
