Abstract

The shaft (6) of the crossbow bolt is threaded (9) to receive a screw-on socket (1), this latter having a parallel bore passing centrally down it. At the threaded end, this bore is widened to form a shoulder to hold the head of a replaceable point (4). This point has an annular groove below the head locating an O-ring seal (7) which holds the point in place and permits some elasticity when tightening up. The sleeve is removed and replaced by an integral lever, turning on pivots (2) and folding away when not required.

Description

DESCRIPTION
La présente invention concerne les instruments du type "pointe de flèche" permettant de changer de pointe sans pour cela changer de flèche.DESCRIPTION
The present invention relates to instruments of the "arrowhead" type enabling the tip to be changed without changing the arrow.

Dans les dispositifs connus, la flèche est pointue à une extrémité et est très vite inutilisable. On connait aussi d'autres dispositifs dans lesquels un outillage est nécessaire pour dissocier la pointe de la flèche sans pour cela être certain de pouvoir réutiliser la douille porteuse car le filetage est souvent deterioré.  In known devices, the arrow is pointed at one end and is quickly unusable. Other devices are also known in which a tool is necessary to dissociate the tip of the arrow without being certain of being able to reuse the carrying bush because the thread is often deteriorated.

Dans le dispositif suivant l'envention permet d'éviter ces inconvénients. In the device according to the invention avoids these drawbacks.

Dans celui-ci, en effet, il est possible de changer de pointe sans outillage, tout en conservant la flèche et la douille.In this one, in fact, it is possible to change the point without tools, while retaining the arrow and the socket.

Le dispositif, objet de l'invention, comporte une douille porteuse d'un ardillon mobile dont la pointe vient se loger dans ladite douille. La flèche qui se vi à l'autre extrémité de la douille permet d'associer la fleche à la pointe. The device, object of the invention, comprises a socket carrying a movable barb, the tip of which is housed in said socket. The arrow which lives at the other end of the socket allows the arrow to be associated with the tip.

Selon une réalisation de l'invention, les tourillons sont usines dans la masse sur la douille, permettant une fiable mobilité de l'ardillon. According to one embodiment of the invention, the pins are factory in the mass on the sleeve, allowing reliable mobility of the pin.

Selon une autre réalisation de l'invention, la pointe possède une gorge conique qui reçoit une petite bague élastique permettant un léger coincement de ladite pointe dans l'alésage de la douille, ceci afin d'éviter de perdre la pointe au cours des manipulations de vissage et dévissage de la flèche. According to another embodiment of the invention, the point has a conical groove which receives a small elastic ring allowing a slight wedging of said point in the bore of the sleeve, this in order to avoid losing the point during handling of screwing and unscrewing the boom.

Le dessin annexé illustre à titre d'ensemple Un xode dê réalisation du dispositif, conforme à la présente invention
Tel qu'il est représenté, le dispositif comDorte -Fig.l- une douille (1) dont les deux tourillons (2) usinés sur la douille permettent la mobilité de l'ardillon (3).The accompanying drawing illustrates, by way of example, an embodiment of the device, in accordance with the present invention.
As shown, the device comDorte -Fig.l- a bush (1) whose two pins (2) machined on the bush allow the mobility of the barb (3).

Fig.2- une partie de l'alésage de la douille (1) permet la réception de la pointe amovible (4) l'autre partie, filetée (5) permet de visser la flèche (6) et par conséquent, à prendre appui directement sur la tête de la pointe (4) afin d'eviter la détérioration des filets (5) lors des percussions. D'autre part, la pointe amovible (4) dont une partie est représentée en coupe, porte une petite bague elastique (7) logée dans une gorge légèrement conique, afin de permettre un léger coincement de ladite pointe dans l'alésage de la douille (1) permettant par le fait de ne pas perdre la pointe (4) lors des manoeuvres de vissage et dévissage de la fleche (5)
Le dispositif, objet de l'invention, peut être utilisé dans tous les cas où la pointe d'une flèche d'arbalète demande toujours à être en bon etat et aisee à changer, particulièrement dans l'eau puisque le changement d'une pointe ne demande aucun outillage. Fig. 2- part of the bore of the sleeve (1) allows the reception of the removable tip (4) the other part, threaded (5) allows to screw the arrow (6) and therefore to be supported directly on the head of the point (4) in order to avoid deterioration of the threads (5) during percussion. On the other hand, the removable tip (4), part of which is shown in section, carries a small elastic ring (7) housed in a slightly conical groove, in order to allow a slight wedging of said tip in the bore of the sleeve. (1) allowing, by not losing the point (4) during the screwing and unscrewing maneuvers of the arrow (5)
The device, object of the invention, can be used in all cases where the tip of a crossbow arrow always needs to be in good condition and easy to change, particularly in water since the change of a tip requires no tools.
