Abstract

A device for connecting a general traction cable and a bicycle, particularly applicable to ski-lifts, for hauling uphill bicycles or like machines, and in particular bicycles used for cross-country or off-the-highway cycling, outside the winter season. The device includes a towing part which is connected to the traction cable via an individual traction cable or individual traction bar. A towed part is connected to the bicycle and a safety device is provided for coupling the two towing and towed parts, with automatic connection by engagement of one of these two parts in the other. This coupling device includes, taking into account the effect of a tension regulator device, a disconnecting device operating on the towed part and releasing the cycle when the rider so desires and possibly in an automatic safety mode. The coupling device also includes an automatic disconnection device operating on the towing part and releasing the cycle when it deviates from the normal path or when it falls on the ground.

Description

La présente invention concerne un dispositif de liaison entre un câble tracteur et un cycle, applicable notamment aux remonte-pentes pour assurer la remontre, en dehors de la saison hivernale, de cycles ou engins similaires et notamment de cycles utilisés pour la pratique du vélocross et du vélo tout terrain.The present invention relates to a connecting device between a towing cable and a cycle, applicable in particular to ski lifts to ensure the recovery, outside of the winter season, of cycles or similar machines and in particular of cycles used for the practice of velocross and mountain biking.

Actuellement le vélocross et le vélo tout terain sont des sports qui se développent considérablement, et il est particulièrement attractif de les pratiquer dans des régions montaqneuses, du fait des possibilités sportives offertes pour les descentes en vélocross, et de la beauté et de la variété des paysages pour les randonnées. Toutefois la pratique du vélocross sur des terrains pentus exige, après chaque descente, une remontée qui ne peut s'effectuer qu'à pied en poussant le cycle. De même, la pratique du vélo du tout terrain implique de longues montées, exténuantes pour les randonneurs.Velocross and mountain biking are currently sports which are developing considerably, and it is particularly attractive to practice them in mountainous regions, because of the sporting possibilities offered for the descents in velocross, and of the beauty and the variety of landscapes for hiking. However, the practice of velocross on steep terrain requires, after each descent, an ascent which can only be done on foot by pushing the cycle. Similarly, mountain biking involves long climbs, exhausting for hikers.

nr il existe, dans beaucoup d'endroits, des remonte-pentes qui sont en général inutilisés en été. On peut donc envisager de tirer partie de l'existence de ces remonte-pentes, pour assurer la remontée de cycles durant les périodes où il n'y a pas de neige, et permettre ainsi la pratique du vélocross en descente, dans les conditions les plus agréables possibles. Mais la traction des cycles présente deux différences importantes par rapport à celle des autres engins habituellement tractés par les remonte-pentes.nr there are, in many places, ski lifts which are generally unused in summer. We can therefore consider taking advantage of the existence of these ski lifts, to ensure the ascent of cycles during periods when there is no snow, and thus allow the practice of velocross downhill, in the conditions as pleasant as possible. But the traction of the cycles presents two important differences compared to that of the other machines usually towed by the ski lifts.

  • - Le cycliste dispose d'une autonomie totale lui permettant de passer d'un remonte-pente à l'autre au cours de ses randonnées, et dans de nombreux cas il est lui-même propriétaire de son cycle.- The cyclist has total autonomy allowing him to go from one ski lift to another during his hikes, and in many cases he is himself the owner of his cycle.
  • - Le cycliste doit, en cours de traction, piloter son engin en tenant compte des secousses infligées à l'engin par les inégalités de la piste, et des variations brutales des efforts de traction qu'elles induisent.- The cyclist must, during traction, control his machine taking into account the tremors inflicted on the machine by the unevenness of the track, and the brutal variations of the traction forces which they induce.

Le dispositif d'accrochaqe du cycle au câble de traction du remonte-pente doit donc répondre à trois conditions:

  • - Assurer la fiabilité de l'accrochage malgré les secousses et les variations brutales des efforts de traction.
  • - Permettre un décrochage par le jeu de la partie du dispositif fixée au cycle, fonctionnant soit à l'initiative du cycliste, soit 'en sécurité automatique.
  • - Assurer un décrochage de sécurité automatinue nar le jeu de la partie du dispositif rattachée au câble du remonte-pente, qui seule demeure sous un contrôle permanent de l'exploitant du remonte-pente pouvant en qarantir la fiabilité de fonctionnement .
The device for attaching the cycle to the pull cable of the ski lift must therefore meet three conditions:
  • - Ensure the reliability of the attachment despite jolts and sudden variations in tensile forces.
  • - Allow the part of the device fixed to the cycle to drop out by playing, operating either on the initiative of the cyclist, or 'in automatic safety.
  • - Ensure an automatic safety stall in the play of the part of the device attached to the cable to the ski lift, which alone remains under permanent control of the operator of the ski lift, which can guarantee its operational reliability.

Aucun des dispositifs existants de traction d'engins par les remonte-pentes ne répond à ces trois conditions:

  • - soit qu'ils n'offrent pas une garantie suffisante contre les secousses infligées à l'engin par les inégalités de la piste et contre les variations brutales des efforts de traction qu'elles induisent, ce qui est le cas des dispositifs décrits dans les brevets DE-A-1913373 et DE-A-2334308 : FR-A-2005456;
  • -soit qu'ils ne permettent pas le décrochage par le jeu de la partie du dispositif fixée à l'engin (Brevets DE-A-2334308, FR-A-2nn5456, US-A-3942452);
  • -soit qu'ils ne permettent pas un décrochage de sécurité automatique par le jeu de la partie du dispositif rattachée au câble du remonte-pente (brevet DE-A-1913373).
None of the existing devices for traction of machines by ski lifts meets these three conditions:
  • - either that they do not offer a sufficient guarantee against the tremors inflicted on the machine by the unevenness of the track and against the sudden variations in the traction forces which they induce, which is the case of the devices described in the patents DE-A-1913373 and DE-A-2334308: FR-A-2005456;
  • -or that they do not allow the part by the device attached to the machine to be detached by play (Patents DE-A-2334308, FR-A-2nn 545 6, US-A-3942452);
  • -or that they do not allow an automatic safety release by the play of the part of the device attached to the cable of the ski lift (patent DE-A-1913373).

Le but de la présente invention est d'assurer l'accrochage des cycles au câble des remonte-pentes en répondant à toutes les conditions précédemment exposées.The purpose of the present invention is to ensure the attachment of the cycles to the cable of the ski lifts by meeting all the conditions previously exposed.

A cet effet ce dispositif de liaison entre un câble tracteur général et un cycle, applicable notamment aux remonte-pentes pour assurer la remontée, en dehors de la saison hivernale, de cycles et engins similaires et notamment de cycles tout terrain utilisés pour la pratique du vélocross et du vélo tout terrain, est caractérisé en ce qu'il comporte une partie tractrice qui est reliée au câble tracteur général par l'intermédiaire d'un régulateur de tension, d'un câble tracteur individuel ou une barre tractrice individuelle, dotés l'un et l'autre d'un dispositif régulateur de tension, une partie tractée reliée au cycle et un dispositif d'accouplement de sécurité entre les deux parties tractrice et tractée, à accrochage automatique par engagement de l'une de ces deux parties dans l'autre, ce dispositif d'accouplement comprenant, compte-tenu de l'effet du dispositif de régulation de tension, des moyens de décrochage opérant sur la partie tractée et libérant le cycle lorsque le conducteur le désire et éventuellement en sécurité automatioue, ainsi que des moyens de décrochage automatique opérant sur la partie tractrice, et libérant le cycle lorsque celui-ci dévie de la trajectoire normale de remontée ou lorsqu'il tombe sur le sol.To this end, this connecting device between a general tractor cable and a cycle, applicable in particular to ski lifts to ensure the ascent, outside the winter season, of cycles and similar machines and in particular of all-terrain cycles used for the practice of velocross and mountain bike, is characterized in that it comprises a tractor part which is connected to the general tractor cable by means of a tension regulator, an individual tractor cable or an individual tractor bar, provided with the both of a device tension regulator, a towed part connected to the cycle and a safety coupling device between the two tractor and towed parts, with automatic coupling by engagement of one of these two parts in the other, this coupling device comprising , taking into account the effect of the tension regulation device, stall means operating on the towed part and releasing the cycle when the driver so desires and possibly in automatic safety, as well as automatic stall means operating on the part tractor, and releasing the cycle when it deviates from the normal ascent trajectory or when it falls on the ground.

Le décrochage automatique du cycle est obtenu en utilisant le fait que, dans les deux cas précités, le plan vertical longitudinal du cycle parvient à faire un angle minimal avec l'axe du câble tracteur individuel ou de la barre tractrice individuelle.The automatic release of the cycle is obtained by using the fact that, in the two aforementioned cases, the longitudinal vertical plane of the cycle manages to make a minimum angle with the axis of the individual tractor cable or of the individual tractor bar.

  • Figure 1 is a schematic elevational view of a connecting device between a general tractor cable and a cycle, according to the invention.
  • Figure 2 is a horizontal sectional view of an embodiment of a safety coupling device between the tractor part and the towed part, in the coupled position.

Le dispositif suivant l'invention est prévu pour établir une liaison entre un cycle 1 , par exemple du type utilisé pour la pratique du vélocross et du vélo de randonnée, et un câble tracteur général 2 tel que celui d'un remonte-pente déjà installé dans une région montaqneuse, en vue d'assurer la remontée du cycle 1 et de son conducteur, sans que ce dernier ait à produire un effort physique important.The device according to the invention is intended to establish a connection between a cycle 1, for example of the type used for the practice of velocross and touring bike, and a general tractor cable 2 such as that of an already installed ski lift in a mountainous region, in order to ensure the ascent of cycle 1 and its driver, without the latter having to produce significant physical effort.

Le dispositif de liaison comprend un dispositif d'accouplement de sécurité 3 entre une partie tractrice 4 reliée au câble tracteur général 2 et une partie tractée 5 reliée au cycle 1.The connection device comprises a safety coupling device 3 between a tractor part 4 connected to the general tractor cable 2 and a towed part 5 connected to cycle 1.

La partie tractrice 4 est reliée au câble tracteur général 2 par l'intermédiaire d'un régulateur de tension 6, du type articulé à ressort, lequel est accroché à l'extrémité inférieure d'un câble tracteur individuel 7 (ou d'une barre tractrice individuelle) qui est lui-même accroché, à son extrémité supérieure, au câble tracteur général 2, par l'intermédiaire d'un dispositif de fixation 8 de tout type approprié.The tractor part 4 is connected to the general tractor cable 2 by means of a tension regulator 6, of the articulated spring type, which is hooked to the lower end of an individual tractor cable 7 (or of a bar individual tractor) which is itself hooked, at its upper end, to the general tractor cable 2, by means of a fixing device 8 of any suitable type.

Le dispositif d'accouplement de sécurité 3 permet un accrochage automatique des deux parties tractrice 4 et tractée 5, par engagement de l'une de ces parties femelle dans l'autre partie mâle, et également un décrochage soit manuel lorsque le conducteur arrive au sommet de la pente et désire libérer le cycle, soit automatique en cas de chute du cycle ou de déviation entraînant un angle trop important avec l'axe de traction.The safety coupling device 3 allows an automatic hooking of the two tractor 4 and towed 5 parts, by engagement of one of these female parts in the other male part, and also a manual stall when the driver reaches the top of the slope and wishes to release the cycle, either automatic in the event of a fall in the cycle or deviation resulting in an excessive angle with the axis of traction.

Une forme d'exécution non limitative du dispositif d'accouplement de sécurité est représentée sur les figures 2 et 3.A non-limiting embodiment of the safety coupling device is shown in FIGS. 2 and 3.

La partie tractrice 4 est constituée par un corps 9 supportant le mécanisme de traction et de sécurité, ce corps 9 ayant une forme destinée à recevoir dans sa partie postérieure évidée un corps 10 de la partie tractée 5, en vue d'éviter toute rotation relative de ces deux corps 9, 10 en position d'accrochage et de faciliter le déboîtement lorsque l'axe de traction présente un anqle minimal avec l'axe du dispositif.The traction part 4 is constituted by a body 9 supporting the traction and safety mechanism, this body 9 having a shape intended to receive in its hollowed out rear part a body 10 of the towed part 5, in order to avoid any relative rotation of these two bodies 9, 10 in hooking position and to facilitate disengagement when the axis of traction has a minimum angle with the axis of the device.

Le mécanisme de traction et de sécurité de la partie tractrice 4 comporte un ensemble de deux mâchoires 11,12, constituées par des leviers à deux bras, montres resnective- ment à pivotement, sur le corps 9 de la partie tractrice 4, autour d'axes respectifs 13,14, portés par le corps 9. Les extrémités postérieures lla,12a, des bras postérieurs de ces mâchoires 11,12, c'est-à-dire celle qui sont situées du côté de la partie tractée 5, sont normalement maintenues bloquées en position de fermeture; en cas de traction axiale, par des bossages 15,16, d'une came de sécurité 17 montée pivotement, dans la partie antérieure du corps 9, autour d'un axe 18. Les bossages latéraux 15,16 de la came 17 sont prévus dans des positions telles qu'en cas de traction axiale ces deux bossages 15,16 se trouvent respectivement en regard de et en contact avec les extrémités antérieures respectives llb,12b, des bras antérieurs des deux mâchoires 11,12. La came de sécurité 17 est solidaire d'un bras rie traction 19 qui la prolonge vers l'avant, à l'extérieur du corps 9, et qui est relié au câble de traction par le régulateur de tension, et par le câble tracteur individuel ou la barre tractrice individuelle. De ce fait la came 17 pivote constamment, en cas de tractionnon axiale, autour de l'axe 18 afin de suivre exactement les mouvements de l'axe de traction par rapport au plan longitulinal vertical du cycle. En l'absence de tout effort de traction axiale, la came de sécurité 17 est maintenue, par un ressort de rappel 20, en position de repos médiane dans laquelle elle assure le blocage des deux mâchoires 11 en position de fermeture, du fait que ses deux bossaqes 15,16 repoussent respectivement vers l'extérieur les extrémités antérieures llb,12b les deux mâchoires 11,12. Ainsi les extrémités postérieures l1a,12a des deux mâchoires 11,12, sont serrées l'une vers l'autre et elles maintiennent entres elles un ergot 21 solidaire du corps 10 de la partie tractée 5.The traction and safety mechanism of the tractor part 4 comprises a set of two jaws 11, 12, constituted by levers with two arms, watches resnective pivotally, on the body 9 of the tractor part 4, around respective axes 13,14, carried by the body 9. The posterior ends 11a, 12a, of the posterior arms of these jaws 11,12, that is to say those which are situated on the side of the towed part 5, are normally kept locked in the closed position; in the event of axial traction, by bosses 15, 16, of a safety cam 17 pivotally mounted, in the front part of the body 9, around an axis 18. The lateral bosses 15, 16 of the cam 17 are provided in positions such that in the event of axial traction, these two bosses 15, 16 are located respectively opposite and in contact with the respective anterior ends 11b, 12b, of the anterior arms of the two jaws 11, 12. The safety cam 17 is integral with a traction arm 19 which extends it forwards, outside the body 9, and which is connected to the traction cable by the tension regulator, and by the individual tractor cable or the individual drawbar. As a result, the cam 17 pivots constantly, in the case of an axial tractionion, about the axis 18 in order to follow exactly the movements of the traction axis relative to the vertical longitudinal plane of the cycle. In the absence of any axial tensile force, the safety cam 17 is maintained, by a return spring 20, in the middle rest position in which it ensures the locking of the two jaws 11 in the closed position, because its two bosses 15,16 respectively push outward the anterior ends llb, 12b the two jaws 11,12. Thus the rear ends 11a, 12a of the two jaws 11, 12 are clamped towards one another and they hold together a lug 21 integral with the body 10 of the towed part 5.

En cas de déviation de l'axe de traction par rapport au plan vertical longitudinal du cycle,la rotation de la came de sécurité 17, dans un sens ou dans l'autre autour de l'axe 18 (figure 3), provoque l'effacement des bossages de blocage 15,16, si bien que les extrémités antérieures 11b,12b des mâchoires 11,12 ne sont plus immobilisées. De ce fait les machôires 11,12 se trouvent être libérées et l'ernot 21 peut alors échapper de lui-même à l'emprise des extrémités postérieures 11a,12a des deux mâchoires 11,12. Le cycle est alors automatiquement libéré.In the event of deviation of the traction axis from the longitudinal vertical plane of the cycle, the rotation of the safety cam 17, in one direction or the other around the axis 18 (FIG. 3), causes the erasure of the locking bosses 15,16, so that the anterior ends 11b, 12b of the jaws 11,12 are no longer immobilized. As a result, the jaws 11,12 are found to be released and the pin 21 can then escape by itself from the grip of the posterior ends 11a, 12a of the two jaws 11,12. The cycle is then automatically released.

L'ergot 21 est avantageusement ménagé à l'extrémité antérieure d'une platine 22 qui est supportée par un ressort 23 permettant à la fois le pivotement de l'ergot 21 vers le bas, pour libérer volontairement le cycle, et son rappel vers le haut, pour l'encliquetage de la partie tractée 5 dans la partie tractrice 4. L'effacement manuel de l'ergot 21 peut être réalisé par une traction exercée vers le bas sur un câble 24 relié à l'ergot 21.The lug 21 is advantageously provided at the front end of a plate 22 which is supported by a spring 23 allowing both the pivoting of the lug 21 downwards, to deliberately release the cycle, and its return towards the top, for snap-fastening of the towed part 5 into the towing part 4. Manual erasure of the lug 21 can be achieved by pulling downwards on a cable 24 connected to the lug 21.

Dans la variante d'exécution illustrée sur la figure 5 l'ergot 21 est solidaire d'un bras 25 monté à pivotement autour d'un axe horizontal et transversal 26 et repoussé vers le haut par un ressort 27. Là encore un câble de traction 24 accroché à l'ergot 21 permet de faire pivoter celui-ci vers le bas, à l'encontre de la force exercée par le ressort 27, pour libérer la partie tractée 5 de la partie tractrice 4.In the variant illustrated in FIG. 5, the lug 21 is secured to an arm 25 pivotally mounted about a horizontal and transverse axis 26 and pushed upwards by a spring 27. Again a pull cable 24 attached to the lug 21 makes it possible to pivot the latter downwards, against the force exerted by the spring 27, to release the towed part 5 from the towing part 4.
