Abstract
Description
Grappin destiné particulièrement au mouillage de bouée de signalisation de chasse sous-marine ou de petites embarcations. Grapple particularly intended for the anchoring of spearfishing signaling buoys or small boats.
Le mouillage des embarcations se fait avec des grappins à branches pliantes autour d'une hampe fixe, le verrouillage des branches se fait généralement par un anneau. The mooring of boats is done with grabs with folding branches around a fixed pole, the locking of the branches is generally done by a ring.
Ces modèles sont souvent trop lourds et trop encombrants pour être utilisés par un chasseur sous-marin apnéiste dérivant dans le courant. A cet usage de fabrication personnelle, on observe des grappins de petites tailles à branches fixes.These models are often too heavy and too bulky to be used by a freediver hunter drifting in the current. For this personal production use, small grapples with fixed branches are observed.
La présente invention a pour objet un grappin pratique par ses dimensions, son poids et ses possibilités de transformation à l'ancrage. The present invention relates to a practical grapple by its dimensions, its weight and its possibilities of transformation at anchoring.
On comprendra bien l'invention à la lecture de la description qui va suivre et en référence aux dessins annexés dans lesquels
Fig. 1 : position (A) fermé représente le grappin en coupe longitudinale.The invention will be clearly understood on reading the description which follows and with reference to the appended drawings in which
Fig. 1: closed position (A) represents the grapple in longitudinal section.

Fig. 4 : représente le grappin suivant une coupe AA de la Fig. 2. Fig. 4: represents the grapple according to a section AA of FIG. 2.
Fig. 5 : représente le grappin avec un corps en variante de forme
Fermé en position (A), ardillons escamotés, position transport et mouillage sur épaves (moins de risques d 'enraguage). Fig. 5: represents the grappling hook with a variant shape body
Closed in position (A), barbs retracted, transport position and mooring on wrecks (less risk of wrapping).
Ouvert en position (B), ardillons sortis, accrochage du bout à l'épingle (8) ; l'épingle (7) se trouve décalée et favorise le mouillage sur fond d'algues. Open in position (B), barbs out, hooking from tip to pin (8); the pin (7) is offset and promotes wetting on a background of algae.
La manoeuvre des différentes positions (A), (B), (C) est réalisée en faisant coulisser les épingles (7) et (8) dans le corps (1). The operation of the different positions (A), (B), (C) is carried out by sliding the pins (7) and (8) in the body (1).
Un corps (1) de forme cylindrique de préférence, composé d'un lest (2) de plomb par exemple, percé de trous (3) est inséré par moulage par exemple dans une chemise (4) en matière dure, un tube en acier inox par exemple, protection du lest aux chocs. A la base du lest, une alvéole (5) formée ici par la chemise (4) plus longue que le lest (2). A body (1) preferably of cylindrical shape, composed of a ballast (2) of lead for example, pierced with holes (3) is inserted by molding for example in a jacket (4) of hard material, a steel tube stainless steel for example, ballast protection against shocks. At the base of the ballast, a cell (5) formed here by the jacket (4) longer than the ballast (2).
Au moins deux épingles (7) et (8), réalisées en fil plié du rond par exemple, coulissent dans les trous (3). La partie supérieure de l'épingle (7) et (8) est en forme d'anse (9) favorisant l'accrochage d'un bout. La partie médiane forme une hampe (10) et aux extrémités inférieures s'articulent autour d'un axe (11) des branches (12), ici des ardillons communément employés sur dès flèches de fusils sous marins. Elles forment ouvert positions (A) et (B) à 800 une sorte de crochet permettant l'ancrage. Le principal intérêt est d'avoir un échelonnage des épingles (7) et (8) qui sont indépendantes, afin de mieux accrocher les algues.At least two pins (7) and (8), made of wire folded from the round for example, slide in the holes (3). The upper part of the pin (7) and (8) is in the form of a handle (9) favoring the attachment of one end. The middle part forms a shaft (10) and at the lower ends are articulated around an axis (11) of the branches (12), here barbs commonly used on arrows of submarine rifles. They form open positions (A) and (B) at 800 a kind of hook allowing anchoring. The main interest is to have a ladder of pins (7) and (8) which are independent, in order to better hang the algae.
La figure 5 représente une variante du corps, ici en forme ovoide. Figure 5 shows a variant of the body, here in ovoid shape.
