A gripping handle (5) is rigidly fixed to the arm (1). A grip (6) fixed on the handle is perpendicular to the handle, and rotates the handle to pinch the log before lifting the log. The grip maintains a pinching effort of the log in combination with lifting and pinching actions generated by the handle, during lifting and displacement of the log, where the grip and the handle are maintained by two hands.

Description

-1- DISPOSITIF DE PREHENSION DE BUCHES POUR L'ALIMENTATION D'UN FOYER DE-1- DEVICE FOR PREHENSION OF BUCHES FOR SUPPLYING A FIREPLACE

CHEMINEE DESCRIPTION L'invention concerne un dispositif de préhension de bûches pour l'alimentation d'un foyer de cheminée, du genre comprenant : a) deux bras articulés maintenus, à l'une de leurs extrémités, par un axe d'articulation et pourvus, à l'autre de leurs extrémités, de griffes aptes à saisir, par pincement, une bûche au niveau de ses bords transversaux ; b) un manche de préhension fixé, à l'une de ses extrémités, de manière rigide, à l'un des deux bras et dont l'axe est orthogonal au plan dans lequel lesdits bras se déplacent. La saisie d'une bûche en vue d'alimenter le foyer d'une cheminée, n'est pas chose aisée, d'une part, de par la forme des bûches, leur encombrement et leur poids et, d'autre part, de par la profondeur des foyers qu'ils soient ou non équipés d'inserts. Tout dispositif à pinces consistant à saisir une bûche avec deux bras articulés, n'est pas, par nature, stable et nécessite des pressions importantes pour son maintien en vue de son déplacement, opération d'autant plus difficile que les bras doivent avoir une certaine longueur pour bien positionner la bûche à l'intérieur du foyer sans se brûler. L'invention vise à réaliser un dispositif à bras articulées, simple de mise en oeuvre, stable, auto verrouillant, qui se caractérise essentiellement par l'adjonction d'une poignée de préhension, fixée sur le manche de préhension, perpendiculairement à celui-ci, apte à : a) mettre en rotation, par son soulèvement, ledit manche de manière à pincer la bûche avant son soulèvement ; b) maintenir l'effort de pincement de ladite bûche, pendant son soulèvement et son déplacement, en combinaison avec l'action de soulèvement et de pincement engendré par le manche. Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'au moins un mode de réalisation préféré de celle-ci donné à titre d'exemple non limitatif et représenté aux dessins annexés. Sur ces dessins : - la figure 1 est une vue de dessus du dispositif de préhension selon l'invention, en position griffes en prise avec une bûche ; - la figure 2 est une vue frontale du dispositif selon l'invention prépositionné en vue d'opérer la saisie d'une bûche ; - la figure 3 est une vue frontale du dispositif de la figure 2 en position de soulèvement de la bûche saisie ; - la figure 4 est une vue frontale du dispositif de la figure 3 en position de libération de la bûche saisie. Le dispositif de préhension de bûches pour l'alimentation d'un foyer de cheminée, représenté aux figures, est du genre comprenant : a) deux bras articulés (1) et (2) maintenus, à l'une de leurs extrémités, par un axe d'articulation (3) et pourvus, à l'autre de leurs extrémités, de griffes (11) et (21) aptes à saisir, par pincement, une bûche (4) au niveau de ses bords transversaux (41) et (42) ; b) un manche de préhension (5) fixé, à l'une de ses extrémités, de manière rigide, à l'un (1) des deux bras (1) et (2) et dont l'axe (A) est orthogonal au plan (P) dans lequel lesdits bras (1) et (2) se déplacent. L'invention se caractérise essentiellement par l'adjonction d'une poignée de préhension (6), fixée sur le manche de préhension (5), perpendiculairement à celui-ci, apte à : a) mettre en rotation, par son soulèvement, ledit manche (1) de manière à pincer la bûche (4) avant son soulèvement ; b) maintenir l'effort de pincement de ladite bûche (4), pendant son soulèvement et son déplacement, en combinaison avec l'action de soulèvement et de pincement engendré par le manche (5) ; ledit manche (5) et ladite poignée (6) étant maintenus par chacune des deux mains.  The invention relates to a device for gripping logs for feeding a fireplace, of the type comprising: a) two articulated arms held at one of their ends by a hinge pin and provided with , at the other end of their claws, able to grip, by pinching, a log at its transverse edges; b) a gripping handle fixed at one of its ends, rigidly, to one of the two arms and whose axis is orthogonal to the plane in which said arms move. The seizure of a log to feed the fireplace is not easy, on the one hand, by the shape of logs, their size and weight and on the other hand, by the depth of the hearth whether or not they are equipped with inserts. Any gripper device consisting of grasping a log with two articulated arms, is not, by nature, stable and requires significant pressure for its maintenance in view of its displacement, an operation all the more difficult that the arms must have some length to properly position the log inside the fireplace without getting burned. The invention aims to provide a device articulated arms, simple implementation, stable, self-locking, which is characterized essentially by the addition of a handle, attached to the handle gripper, perpendicular to it , able to: a) rotate, by its lifting, said handle so as to pinch the log before its lifting; b) maintain the clamping force of said log, during its lifting and displacement, in combination with the action of lifting and pinching generated by the handle. The features and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment thereof given by way of non-limiting example and shown in the accompanying drawings. In these drawings: FIG. 1 is a view from above of the gripping device according to the invention, in claw position in engagement with a log; - Figure 2 is a front view of the device according to the invention prepositioned for the purpose of operating the seizure of a log; - Figure 3 is a front view of the device of Figure 2 in the lifting position of the seized log; - Figure 4 is a front view of the device of Figure 3 in the release position of the seized log. The log gripping device for feeding a fireplace, shown in the figures, is of the type comprising: a) two articulated arms (1) and (2) held at one of their ends by a articulation pin (3) and provided, at the other end of their ends, with claws (11) and (21) capable of grasping, by pinching, a log (4) at its transverse edges (41) and ( 42); b) a handle (5) fixed at one of its ends, rigidly, to one (1) of the two arms (1) and (2) and whose axis (A) is orthogonal at the plane (P) in which said arms (1) and (2) move. The invention is characterized essentially by the addition of a gripping handle (6), fixed on the handle (5), perpendicular to it, adapted to: a) rotate, by its lifting, said handle (1) so as to pinch the log (4) before its lifting; b) maintain the clamping force of said log (4), during its lifting and displacement, in combination with the lifting and pinching action generated by the handle (5); said handle (5) and said handle (6) being held by each of the two hands.

Selon d'autres particularités de l'invention : - les griffes (11) et (21) peuvent être obtenues par double pliage des extrémités libres des bras (1) et (2) qui possèdent une forme apte à favoriser leur maintien sur les bords transversaux (41) et (42) de la bûche (4) ; - le manche (5) est fixé au bras (1) de manière excentrée par rapport à l'axe d'articulation (3) des bras articulés (1) et (2) ; - le bras (2), libre en rotation, peut être interchangé par un bras de longueur différente afin de l'adapter à différentes longueurs de bûches ; - le manche (5) peut être réalisé au moyen d'un profilé tubulaire ; - l'axe d'articulation (3) peut être réalisé au moyen d'un boulon ou d'un axe goupillé.  According to other features of the invention: - the claws (11) and (21) can be obtained by double folding of the free ends of the arms (1) and (2) which have a shape adapted to promote their maintenance on the edges transverse (41) and (42) of the log (4); - The handle (5) is fixed to the arm (1) eccentrically relative to the hinge axis (3) of the articulated arms (1) and (2); - The arm (2), free in rotation, can be interchanged by an arm of different length to adapt to different lengths of logs; - The handle (5) can be achieved by means of a tubular profile; - The hinge axis (3) can be achieved by means of a bolt or a pinned pin.
