Abstract

1. Splitting wedge for a wood cutter, characterized by the fact that it is asymmetrical and is provided with a flat face, constituting its basis, intended to be in contact with the stock of the bole to be cut, when the wedge is engaged in a slot provided in this bole, and with an active face forming, with the said basis, an angle which is increasing from the front end of the wedge in the direction of its rear end.

Description

La présente invention a pour objet un coin d'abattage pour bûcheron.The present invention relates to a felling corner for a lumberjack.

Les coins d'abattage pour bûcherons utilisés actuellement ont leurs deux faces, convergeant vers l'extrémité antérieure du coin, qui sont planes. Ces faces sont, le plus généralement, munies de nervures longitudinales de guidage.The logging felling corners currently used have their two faces, converging towards the anterior end of the corner, which are flat. These faces are, most generally, provided with longitudinal guide ribs.

L'inconvénient de tels coins réside dans le fait qu'ils sont peu performants, l'angle, constant, que forment les deux faces du coin l'une avec l'autre ne pouvant convenir à la fois à la phase initiale de pénétration du coin dans la taille, c'est-à-dire la fente préalablement ménagée à la tron- conneuse dans le tronc, et à la phase finale de cette pénétration. De plus, ces coins présentent un certain danger en ce sens que, souvent, et spécialement lorsque le travail s'effectue dans l'humidité, par exemple sous la pluie, le coin est éjecté par la pression exercée sur lui par les deux lèvres de la taille, risquant de blesser le bûcheron.The drawback of such corners lies in the fact that they are ineffective, the constant angle formed by the two faces of the corner with each other not being suitable for both the initial phase of penetration of the wedge. wedge in the waist, that is to say the slot previously made in the chainsaw in the trunk, and in the final phase of this penetration. In addition, these corners present a certain danger in the sense that often, and especially when the work is carried out in humidity, for example in the rain, the corner is ejected by the pressure exerted on it by the two lips of pruning, risking injury to the woodcutter.

Le but de la présente invention est de supprimer ces inconvénients.The object of the present invention is to eliminate these drawbacks.

Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1.

Le dessin représente, à titre d'exemple, deux formes d'éxécution de l'objet de l'invention.The drawing represents, by way of example, two forms of execution of the object of the invention.

La fig. 1 est une vue en perspective d'une première forme d'exécution d'un coin d'abattage.Fig. 1 is a perspective view of a first embodiment of a felling corner.

La fig. 2 est une vue en élévation de ce coin d'abattage, etFig. 2 is an elevational view of this felling corner, and

La fig. 3 est une vue en perspective d'une deuxième forme d'exécution de coin d'abattage.Fig. 3 is a perspective view of a second embodiment of a felling corner.

Le coin d'abattage représenté aux figures 1 et 2, désigné par 1, en aluminium ou en matière plastique, présente une face plane 2, formant sa base, et une face 3 constituée par trois pans 3a, 3b et 3c formant chacun un angle différent, désigné par a, P, et y, respectivement, avec la face 2 du coin. L'angle a, situé à l'extrémité antérieure du coin, est le plus faible, et l'angle y le plus grand.The felling wedge shown in Figures 1 and 2, designated by 1, made of aluminum or plastic, has a flat face 2, forming its base, and a face 3 formed by three sides 3a, 3b and 3c each forming an angle different, designated by a, P, and y, respectively, with side 2 of the corner. The angle a, located at the anterior end of the corner, is the smallest, and the angle y the largest.

Grâce à cette disposition, l'efficacité du coin est améliorée et le risque qu'il soit éjecté par la pression du tronc grandement réduit.Thanks to this arrangement, the efficiency of the wedge is improved and the risk of it being ejected by the pressure of the trunk greatly reduced.

La face supérieure 3 du coin présente une nervure longitudinale de guidage 1a s'étendant sensiblement sur toute la longueur du coin, alors que la face inférieure 2 de celui-ci présente une nervure longitudinale 1b, relativement courte, située dans la zone central du coin. La tête du coin, désignée par 1c, est percée d'un trou borgne 4 destiné à recevoir une touche sur laquelle le bûcheron frappe avec une masse. Cette touche pourra être en matière plastique ou en bois, par exemple.The upper face 3 of the corner has a longitudinal guide rib 1a extending substantially over the entire length of the corner, while the lower face 2 of the latter has a relatively short longitudinal rib 1b located in the central area of the corner . The head of the corner, designated by 1c, is pierced with a blind hole 4 intended to receive a touch on which the woodcutter strikes with a mass. This key can be made of plastic or wood, for example.

Dans la forme d'exécution de la figure 3, le coin, désigné par 5, présente une face plane 6 formant sa base et une face 7, concave, munie de deux nervures de guidage 5a. L'angle que forme la face 7 avec la face 6 va en croissant de l'extrémité antérieure du coin, où la face 7 tend asymptoti- quement à rejoindre la face 6, à l'extrémité postérieure du coin.In the embodiment of Figure 3, the corner, designated by 5, has a flat face 6 forming its base and a face 7, concave, provided with two guide ribs 5a. The angle formed by the face 7 with the face 6 increases from the anterior end of the corner, where the face 7 asymptotically tends to join the face 6, at the posterior end of the corner.

Claims (6)

1. Splitting wedge for a wood cutter, characterized by the fact that it is asymmetrical and is provided with a flat face, constituting its basis, intended to be in contact with the stock of the bole to be cut, when the wedge is engaged in a slot provided in this bole, and with an active face forming, with the said basis, an angle which is increasing from the front end of the wedge in the direction of its rear end.
2. Splitting wedge as claimed in claim 1, characterized by the fact that its active face is provided with several surfaces the angles they form with the basis are different.
3. Splitting wedge as claimed in claim 1, characterized by the fact that its active face is concave.
4. Splitting wedge as claimed in claim 3, characterized by the fact that the said concave face is constituted by a surface tending asymptotically to reach the basis of the wedge at its front end.
5. Splitting wedge as claimed in claim 1, characterized by the fact that it is provided with a rear striking face which is perpendicular to its basis.
6. Splitting wedge as claimed in claim 1, characterized by the fact that at least one of its faces--basis and active face-is provided with at least one longitudinal rib serving to the guiding of the wedge.
