DISPOSITIF ANTI-CHUTE, RETRACTABLE
ADAPTABLE SUR CANNES ANGLAISES
La presente invention concerne un dispositif évitant aux cannes anglaises, lorsqu'elles ne sont plus tenues manuellement, de chuter, quel que soit le sol.
RETRACTABLE FALL PROTECTION DEVICE
ADAPTABLE ON ENGLISH RODS
The present invention relates to a device preventing the English rods, when they are no longer held manually, from falling, whatever the ground.

Traditionnellement, hors une canne spécifique dite"tripate" (fixe), il n'existe pas de cannes qui puissent rester seules debout sans chuter.  Traditionally, apart from a specific cane called "tripate" (fixed), there are no canes that can stand alone without falling.

Le dispositif selon l'invention permet de remédier à cet inconvénient.  The device according to the invention overcomes this drawback.

Il comporte en effet, selon une première caractéristique, 2 pieds annexes fixés en vis à vis par une articulation, sur un manchon coulissant entre une bague de butée et la base de la crosse de canne. Ce manchon est muni d'une poignée de commande.  It has in fact, according to a first characteristic, 2 annex feet fixed opposite by an articulation, on a sliding sleeve between a stop ring and the base of the cane butt. This sleeve is provided with a control handle.

Selon une seconde caractéristique, 2 biellettes symétriques entre elles, relient les pieds annexes à un étrier oscillant fixé sur le manchon. La position de ce dernier (basse ou haute), permet l'écartement latéral ou le refermement des pieds annexes.  According to a second characteristic, 2 symmetrical links between them, connect the annex feet to an oscillating stirrup fixed on the sleeve. The position of the latter (low or high) allows the lateral separation or the closing of the annex feet.

Selon une troisième caractéristique, 2 autres biellettes symétriques entre elles relient les pieds annexes au pied de

Figure img00010001

canne, par l'intermédiaire d'une seconde bague bridée sur celuici. According to a third characteristic, 2 other symmetrical links between them connect the annex feet to the foot of
Figure img00010001

cane, via a second ring clamped on it.

Ces biellettes permettent aux pieds annexes de s'écarter vers l'arrière ou de se refermer en parfaite synchronisation avec les biellettes d'écartement latéral, permettant de former avec le pied de canne, lorsque le manchon est baissé, un trépied dont la base forme un triangle sensiblement équilatéral et lorsque le manchon est relevé, un ensemble parfaitement compact et d'un encombrement minimum, formé par l'alignement des pieds annexes le long du pied de canne. These rods allow the auxiliary feet to move backwards or to close in perfect synchronization with the lateral spacing rods, making it possible to form with the cane foot, when the sleeve is lowered, a tripod whose base forms a substantially equilateral triangle and when the sleeve is raised, a perfectly compact and compact assembly, formed by the alignment of the adjoining feet along the cane foot.

La course du manchon, réglable par la bague de butée, permet aux pieds annexes de remonter d'autant, ce qui autorise l'utilisation normale de la canne sans aucune gêne. The race of the sleeve, adjustable by the stop ring, allows the auxiliary feet to go up by the same amount, which allows normal use of the rod without any discomfort.

Selon une quatrième caractéristique, une rainure de clavetage est pratiquée, de préférence à l'intérieur du manchon et de la bague dite de butée. Une clavette suffisamment longue solidaire de cette dernière a pour but de permettre à la poignée de commande, fixée sur le manchon, de rester en alignement permanent avec l'axe de la poignée de canne.  According to a fourth characteristic, a keying groove is made, preferably inside the sleeve and the so-called stop ring. A sufficiently long key integral with the latter is intended to allow the control handle, fixed on the sleeve, to remain in permanent alignment with the axis of the rod handle.

Selon une cinquième caractéristique, la poignée de commande comporte en son extrémité, un système de verrouillage permettant de maintenir refermés les pieds annexes, le déverrouillage se faisant par simple pression du doigt, ou en frappant d'un coup bref le pied de canne sur le sol.  According to a fifth characteristic, the control handle comprises at its end, a locking system making it possible to keep the adjoining feet closed, the unlocking being done by simple pressure of the finger, or by striking the cane foot with a short blow on the ground.

Selon les modes particuliers de réalisation : - Les articulations des pieds annexes et des biellettes d'écar- tement arrière peuvent être réalisées à l'aide de rotules ou de tout autre système permettant un débattement arrière et latéral.  According to the particular embodiments: - The articulations of the auxiliary feet and the rear spacing rods can be produced using ball joints or any other system allowing rear and lateral movement.

Les autres articulations peuvent être réalisées à l'aide de vis, rivets ou clips, de même que pour le réglage de hauteur des pieds annexes.  The other joints can be made using screws, rivets or clips, as well as for adjusting the height of the ancillary feet.

- La fixation des pieds annexes peut être décentrée vers l'arrière sur le manchon afin de réduire l'encombrement lorsqu'ils sont refermés.  - The attachment of the additional feet can be offset backwards on the sleeve in order to reduce the size when they are closed.

- Le coulissement du manchon peut être aidé par un ressort de compression, de traction ou d'écartement.  - The sliding of the sleeve can be helped by a compression, traction or spacing spring.

- Afin de limiter les jeux et l'encombrement, la fixation des biellettes sur les pieds annexes peut être réalisée en les incluants dans des lumières pratiquées dans ceux-ci. - In order to limit the clearances and the bulk, the fixing of the rods on the annex legs can be carried out by including them in lights practiced in them.

- Le manchon et les bagues sont réalisés de préférence en aluminium coulé ou usiné à partir d'un tube d'une épaisseur minimum de 7 mm. D'autres matériaux pourront être utilisés, sous réserve d'avoir des qualités de glissement et de poids au moins égales.  - The sleeve and the rings are preferably made of cast aluminum or machined from a tube with a minimum thickness of 7 mm. Other materials may be used, provided they have at least equal sliding and weight qualities.

- Le verrouillage de la poignée de commande peut être réalisé par pincement, par basculeur autour de la poignée de canne, ou par tout autre moyen permettant le montage du système en kit, sans jamais modifier la canne d'origine. - The control handle can be locked by pinching, by rocking around the cane handle, or by any other means allowing the assembly of the system as a kit, without ever modifying the original cane.

Selon la figure 3 dans le manchon (1) a été creusée une rainure de clavetage (6) ainsi que dans une bague (7) (dite de butée).  According to Figure 3 in the sleeve (1) has been dug a keyway (6) as well as in a ring (7) (called stop).

Dans cette rainure a été insérée une clavette (8) rendue solidaire de la bague (7), afin de guider toujours dans l'axe le manchon (1). In this groove has been inserted a key (8) made integral with the ring (7), in order to always guide the sleeve (1) in the axis.

Selon la figure 2, la poignée de commande (5) comporte à son extrémité un système de verrouillage (9) par pincement (dans l'option choisie).  According to Figure 2, the control handle (5) has at its end a locking system (9) by pinching (in the chosen option).

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

Selon la figure 2 bis, sur l'étrier oscillant (4) sont fixées 2 biellettes (10) (dites d'écartement latéral), reliées aux pieds annexes (3).  According to Figure 2a, on the oscillating stirrup (4) are fixed 2 rods (10) (called lateral spacing), connected to the auxiliary feet (3).

Sur une seconde bague (11) sont fixées 2 autres biellettes (12) (dites d'écartement arrière), reliées aussi aux pieds annexes (3). On a second ring (11) are fixed 2 other rods (12) (called rear spacers), also connected to the adjoining feet (3).

Ces derniers sont ajustables en hauteur par coulissement des tubes (13). The latter are adjustable in height by sliding the tubes (13).

Selon les figures 1 et 1 bis, la poignée de commande (5) détermine la position du manchon (1). Relevée, les pieds annexes sont remontés et alignés le long du pied de canne. Celle-ci est alors utilisable normalement.  According to Figures 1 and 1a, the control handle (5) determines the position of the sleeve (1). Raised, the adjoining feet are raised and aligned along the cane foot. This can then be used normally.

Selon les figures 2 et 2 bis, la poignée de commande (5) est baissée, les pieds annexes (3) sont déployés, la canne tient alors seule debout. According to Figures 2 and 2a, the control handle (5) is lowered, the auxiliary feet (3) are deployed, the rod then stands alone.
